The present application claims priority over the Chinese patent application dated September 27, 2023, with application numbers 202311267085.5 and 202322645020.1, all contents of which are incorporated into the present application by reference.

Technical field

The present application relates to the technical field of air conditioning systems, in particular a mounting bracket and an air conditioning system.

State of the art

The current state of the art features a split air conditioning system designed for user-friendly installation. This system utilizes flexible refrigerant lines to connect the internal heat exchanger of an indoor unit to the external heat exchanger of an outdoor unit. Furthermore, the refrigerant is pre-filled into the system before delivery from the factory. When installing the system, the user only needs to mount the indoor and outdoor units separately, without having to install the refrigerant lines or fill the system with refrigerant. This reduces installation complexity and allows for user-friendly installation.

A mounting bracket for installing an outdoor air conditioning unit typically comprises a main bracket and a wall-mounted support bracket. One end of the main bracket is mounted to a window frame, while the other end extends from the window and supports the outdoor air conditioning unit. One end of the wall-mounted support bracket is connected to the main bracket, and the other end rests against an exterior wall surface. However, because the dimensions of existing mounting brackets are not adjustable, they cannot be adapted to window sills of varying widths, leading to user complaints.

The present application provides a mounting bracket used for installing an outdoor air conditioning unit. Specifically, the air conditioning unit of the present application can be a split air conditioning system. This facilitates user installation and uses flexible refrigerant lines to connect the internal heat exchanger of an indoor air conditioning unit and the external heat exchanger of the outdoor air conditioning unit. Furthermore, the refrigerant is pre-filled into the refrigerant circuit before the unit leaves the factory. When the user installs the unit themselves, they only need to mount the indoor and outdoor air conditioning units separately, without having to install the refrigerant lines or fill the refrigerant. This reduces installation difficulties and allows for user-assisted installation. However, the present embodiment is not limited to this. In other embodiments, the air conditioning unit of the present application can also be an ordinary split air conditioning system or a one-piece air conditioning system, such as a one-piece window air conditioner. In this case, the outdoor air conditioning unit refers to the part of the window air conditioner that protrudes outwards from the room.

• einen Hauptträger 101, der eine Montagehalterung für Fensterrahmen 10 und eine damit verbundene Traghalterung 30 umfasst, wobei die Montagehalterung für Fensterrahmen 10 an einem Fensterrahmen 923 montiert werden kann und sich die Traghalterung 30 in einer ersten Richtung zur Außenseite des Fensters 92 erstreckt, und wobei die Klimaanlage-Außeneinheit 91 an einer Oberseite der Traghalterung 30 angeordnet ist; und
• einen Stützträger 201, wobei der Stützträger 201 mit der Traghalterung 30 verbunden ist und in der Lage ist, eine Verbindungsposition in der ersten Richtung so zu verstellen, dass sie an einer Außenwandfläche 922 und/oder einem Fensterbrett 921 anliegt.

It will be on 1 to 4 It should be noted that in one embodiment, the mounting bracket is designed to include:

• a main support 101 comprising a mounting bracket for window frame 10 and an associated support bracket 30, wherein the mounting bracket for window frame 10 can be mounted on a window frame 923 and the support bracket 30 extends in a first direction towards the outside of the window 92, and wherein the air conditioning outdoor unit 91 is arranged on a top of the support bracket 30; and
• a support beam 201, wherein the support beam 201 is connected to the support bracket 30 and is able to adjust a connection position in the first direction so that it rests against an outer wall surface 922 and/or a window sill 921.

Specifically, it is from 2 to 4 It is evident that the first direction refers to a direction parallel or approximately parallel to the central axis of the window 92, and that the width of the window sill 921 refers to the distance of the window frame 923 from the outer wall surface 922 in the first direction, as determined by the distance L in 2 As shown, the width of the window sill 921 can vary from building to building, as this width depends on the thickness of the wall in which the window 92 is located, as well as on the mounting position of the window frame 923 on the window 92. Therefore, the mounting bracket, in its fixed size, cannot be easily adapted to the different widths of the window sill 921.

In one embodiment, the support bracket 201 can be adjusted in the first direction with respect to its mounting position on the main beam 101, such that the position of an adjacent end face of the support bracket 201 relative to the mounting bracket for the window frame 10 is adjustable. That is, the distance between the adjacent end face of the support bracket 201 and the mounting bracket for the window frame 10 is adjustable, allowing the adjustable distance to be adapted to the different widths of the window sill 921. Thus, it is advantageous for the user to be able to adjust the mounting position of the support bracket 201 on the main beam 101 themselves. This ensures that the support bracket 201 fits snugly against the outer wall surface 922 and/or the window sill 921, and the mounting bracket can be easily adjusted to the different widths of the window sill 921.

It will be on 5 and 6 As noted, in one embodiment, the support beam 201 comprises a first support section 40, which is connected to the support bracket 30 and extends downwards, wherein the first support section 40 can abut an outer side surface of the window sill 921. Specifically, the window sill 921 normally extends outwards with a section of the outwardly projecting window sill, the width of which varies from building to building. For example, the width of the window sill in 6 The depicted, outwardly projecting window sill is larger than the width of the one shown. 4 The window sill shown projects outwards. In this case, the support bracket 201 can be mounted and fastened using an outer end face of the first support section 40 (i.e., the outer side face of the window sill 921), which rests against the projecting window sill, as shown in 6 depicted.

It will be on 1 to 4 As noted, in some further embodiments, the support beam 201 comprises, in addition to the first support section 40, a second support section 50, wherein the second support section 50 is connected to the first support section 40 at one end and can rest against the outer wall surface 922 at the other end. Because the second support section 50 rests against the outer wall surface 922, the assembly and fastening of the support beam 201 can now be achieved, as shown in 2 and 4 As shown. Of course, in other embodiments, only the first support section 40 can be provided without the second support section 50. In one embodiment, it is further provided that the first support section 40 extends diagonally downwards in one direction near the mounting bracket for window frames 10 and that its lower end can rest directly against the outer wall surface 922. In this case, it is possible that either the first support section 40 rests with one side surface against the wider outer side surface of the window sill 921 or that the first support section 40 rests with its lower end against the outer wall surface 922.

It will be on 2, 4 to 6 It should be noted that in some further embodiments, the first support section 40 and the second support section 50 are detachably connected. This allows the user to flexibly adapt the design of the support bracket 201 to the specific characteristics of the respective window sill 921. For example, the first support section 40 can optionally rest against the window sill 921, or the second support section 50 can rest against the outer wall surface 922, to achieve improved and simpler adaptation to the various shapes of the window sill 921. Of course, in other embodiments, the first support section 40 and the second support section 50 can also be permanently connected. Alternatively, the first support section 40 and the second support section 50 are formed in one piece, as in the embodiments according to the 11 and 12 depicted.

It will be on 1 , 2 and 5 As noted, in one embodiment, the first support section 40 is provided with a second sliding groove 413 along its length, and the second support section 50 comprises a sliding segment 52 and a support segment 53 that intersect, wherein the sliding segment 52 is provided to slide within the second sliding groove 413 and the support segment 53 serves to abut a facade. That is, the support segment 53 and the sliding segment 52 extend obliquely downwards in the direction near the mounting bracket for window frames 10, except that the angles of inclination of the two are set differently, and the angle of inclination of the sliding segment 52 is set to the same angle of inclination as the angle of inclination of the first support section 40. In this way, the second support section 50 is able to adjust its mounting position on the first support section 40 in an up-down direction, thereby adjusting the relative position of the end face of the second support section 50 facing away from the first support section 40 in relation to the mounting bracket for window frame 10, in order to allow the mounting bracket to be adapted to a wider range of width sizes of the window sill 921.

In one embodiment, it is provided that the first support section 40 has at least two first mounting holes 414, which are located in the The second support section 50 is provided with second mounting holes 51 corresponding to the first mounting holes 414, and the second mounting hole 51 is optionally mounted to one of the at least two first mounting holes 414 by means of a fastening element. In one embodiment, the fastening element can be a screw, a pin 81, or a snap fastener. In this way, it is possible to easily adjust the mounting position of the second support section 50 on the first support section 40 and to increase the strength of the connection between the second support section 50 and the first support section 40. Of course, in other embodiments, the second mounting holes 51 may also be omitted. In this case, the second support section 50 is provided with an elastically deformable positioning bead corresponding to the first mounting hole 414, which can be elastically snapped into the first mounting hole 414. In one embodiment, at least two second mounting holes 51 are provided, wherein the at least two second mounting holes 51 are spaced apart from one another along the longitudinal direction of the second sliding groove 413 and are uniquely aligned with the two first mounting holes 414. If the two second mounting holes 51 uniquely align with the two first mounting holes 414 during assembly, the strength of the connection between the second support section 50 and the first support section 40 can be increased, thereby improving the structural stability of the mounting bracket.

In one embodiment, the opening edge of the second sliding groove 413 is further provided that it is bent inwards to form a guide flange 415, and that the second support section 50 is provided with a second chamber 50a with a lateral opening. Second mounting holes 51 are provided in the two opposite side walls of the second chamber 50a. The outer side surfaces of the two opposite side walls of the second chamber 50a each slide against the two side walls of the second sliding groove 413. In addition, the opening edge of the second chamber 50a slides against the inner side surface of the guide flange 415. In this way, the structural strength of the second support section 50 can be increased, and the smoothness and stability of the second support section 50 when sliding in the second sliding groove 413 can be improved.

It will be on 2 and 12 It should be noted that in some embodiments, the first support section 40 extends obliquely downwards in the direction near the mounting bracket for the window frame 10, and the second support section 50 extends obliquely downwards from the first support section 40 in the direction near the mounting bracket for the window frame 10. This improves the structural strength and stability of the mounting bracket. Of course, in other embodiments, it is also possible for the second support section 50 to extend obliquely upwards in the direction near the mounting bracket for the window frame 10, or to extend along a horizontal direction. Alternatively, it is also possible for the first support section 40 to extend obliquely downwards in a direction away from the mounting bracket for the window frame 10, or to extend along a vertical direction.

It will be on 1 and 11 It should be noted that in some embodiments, the mounting bracket further comprises a non-slip pad 82, wherein the non-slip pad 82 is arranged at an end of the second support section 50 facing away from the first support section 40 and serves to bear against the outer wall surface 922. The material of the non-slip pad 82 can, in particular, consist of rubber, silicone, or similar materials, without this application expressly limiting this. In this way, the non-slip pad 82 can increase the static friction to which the support bracket 201 is subjected when bearing against the outer wall surface 922, thereby increasing the stability of the mounting of the support bracket 201 on the outer wall surface 922 and improving the structural stability of the mounting bracket. Of course, in other embodiments, it is also possible that the non-slip pad 82 is not provided and the end surface of the second support section 50 is matte to increase the static friction to which it is subjected when bearing against the wall surface 922.

In one embodiment, the materials of the support beam 201 and the main beam 101 are designed to consist of metal, for example, carbon steel, an aluminum or magnesium alloy, etc., which improves the strength and stiffness of the structure. Of course, in other embodiments, the materials of the support beam 201 and the main beam 101 can be designed to consist of other materials, for example, plastic.

It is understood that there are various structural forms that allow the support beam 201 to adjust the connection position along the first direction. For example, it is applied to 1 , 2 , 11 and 12 It should be noted that in some embodiments, the support bracket 30 is provided on its underside with a first sliding groove 31, in which an upper end of the support beam 201 is slidably arranged. This allows the mounting position of the support beam 201 on the main beam 101 to be easily adjusted. Furthermore, the side wall of the first sliding groove 31 can act as a displacement limiter for the support beam 201 in a left-right direction. This improves the structural stability of the mounting bracket. It should be noted that the left-right direction refers to the distribution direction of the two opposing window sides in the horizontal direction, and the top-bottom direction refers to the distribution direction of the two opposing window sides in the vertical direction. Of course, in other embodiments it is also possible that the first sliding groove 31 is located at the upper end of the support beam 201 and the main beam 101 is arranged to slide in the first sliding groove 31. Alternatively, a guide rail is provided on the left and/or right side surface of the main beam 101. In this case, the support beam 201 is provided with a guide groove corresponding to the guide rail, and the guide rail slides in this guide groove.

It will be on 5 As noted, in one embodiment, the upper end of the support bracket 201 is bent in the first direction to form a first flange 411. The two opposing flanks of the first flange 411 are then bent further downwards to form a second flange 412. These two second flanges 412 are adapted to and embedded in the first sliding groove 31. That is, the second flange 412 is provided in an interference fit with the first sliding groove 31, so that the static friction generated by the tight fit can achieve the relative fixation of the upper end of the support bracket 201 in the first sliding groove 31. If the mounting position of the support bracket 201 needs to be adjusted along the first direction in the first sliding groove 31, it is sufficient to strike the support bracket 201 with a tool such as a hammer. This simplifies the structure of the mounting bracket. Of course, in other embodiments it is also possible that the side wall of the first sliding groove 31 is provided with several first pin holes spaced apart from one another in the first direction, and that the second flange 412 of the support beam 201 is provided with a second pin hole corresponding to the respective first pin hole. The second pin hole is optionally mounted to one of the several first pin holes by means of a pin 81. It is possible that the second flange 412 does not have to be in an interference fit with the first sliding groove 31.

Naturally, the support bracket 201 can also fit the first sliding groove 31 in other shapes. It will be applied to 11 to 13 As noted, in a further embodiment, for example, the first sliding groove 31 is provided with several positioning holes 311 spaced apart from one another in the first direction, with the support beam 201 being provided with a positioning projection 421 corresponding to the respective positioning hole 311. The positioning projection 421 can optionally be inserted into and mounted in one of the several positioning holes 311. In this way, several positioning holes 311 are used for the selective insertion and mounting of the positioning projection 421 in order to adjust the mounting position of the support beam 201 on the main beam 101. This allows for a simpler structure and an improvement in the mounting stability of the support beam 201 on the main beam 101.

It will be on 13 As noted, in one embodiment, the positioning hole 311 is provided in the base surface of the first sliding groove 31, and an upper end face of the support beam 201 is provided with a clearance recess 40b on a side facing away from the positioning projection 421. The clearance recess 40b has a width that increases in the direction away from the positioning projection 421. In this way, the positioning projection 421 projecting from the upper end face of the support beam 201 can be rotated by providing the clearance recess 40b to move into or out of the positioning hole 311. This facilitates the installation of the positioning projection 421 in or out of the positioning hole 311, and thus also the adjustment of the mounting position of the support beam 201 on the main beam 101. Of course, in other embodiments the positioning hole 311 can also be provided in the side wall of the first sliding groove 31. The positioning projection 421 is, for example, designed as an elastically deformable positioning bead.

It will be on 13 As further noted, in another embodiment, the opening of the first sliding groove 31 is bent inwards on both sides to form a limiting flange 312, and the support beam 201 has two opposing sliding walls 422. The sliding wall 422 rests against an end face of the limiting flange 312 in a sliding manner. The sliding wall 422 is provided with a first lug 424 and a second lug 425, which project outwards. The first lug 424 rests slidably against a groove base surface of the first sliding groove 31, and the second lug 425 rests slidably against an inner side surface of the limiting flange 312. The interaction of the first lug 424 with the second lug 425 thus provides a displacement limit for the support beam 201 in the up-down direction, thereby improving the smooth running and stability of the support beam 201 when sliding in the first sliding groove 31. Of course, in other embodiments, it is also possible for the sliding wall 422 of the support beam 201 to be provided with a limiting rib extending in the up-down direction. The limiting rib rests on the base surface of the first sliding groove 31 at its upper end surface and on the inner side surface of the limiting flange 312 at its lower end surface.

It will be on 13 As noted, in a further embodiment, the support beam 201 also has a connecting wall 423 that connects the two sliding walls 422. The connecting wall 423, together with the two sliding walls 422, defines a first chamber 40a with a lateral opening, wherein the clearance recess 40b communicates with and is located adjacent to the opening of the first chamber 40a. An upper end of the connecting wall 423 is bent outwards, forming a transition flange 426. The transition flange 426 is then bent further upwards, forming the positioning projection 421, and an upper end surface of the transition flange 426 rests against the base surface of the first sliding groove 31. The upper end surface of the first lug 424 and the upper end surface of the transition flange 426 are essentially in the same plane. Since the positioning projection 421 and the clearance recess 40b are located on opposite sides of the first lug 424, the first lug 424 can serve as a pivot point for the support beam 201 when the support beam is rotated in the first sliding groove 31. In particular, when the support beam 201 is rotated about this pivot point and the upper end face of the clearance recess 40b is gradually brought closer to the base face of the first sliding groove 31, the positioning projection 421 can gradually disengage from the positioning hole 311. Likewise, it is provided that the positioning projection 421 can gradually retract into the positioning hole 311 when the support beam 201 is rotated about this pivot point and the upper end face of the clearance recess 40b is gradually moved away from the base face of the first sliding groove 31. This allows the structure of the support beam 201 to be simplified and the strength of the connection between the support beam 201 and the main beam 101 to be improved.

It should be noted that the transition flange 426 can increase the strength of the connection between the positioning projection 421 and the connecting wall 423. Of course, the transition flange 426 may also be omitted in other embodiments, in which case the connecting wall 423 extends directly upwards from the positioning projection 421.

In one embodiment, it is further provided that an upper end of the sliding wall 422 is bent outwards to form the first nose 424. That is, the first nose 424, the transition flange 426, and the positioning projection 421 are designed such that the upper flank of the first support section 40 is bent, thus further simplifying the structure of the first support section 40. In other embodiments, the first nose 424 can, of course, also be a convex column welded to the outer side surface of the sliding wall 422.

In one embodiment, the positioning hole 311 is configured as an elongated hole, with the longitudinal direction of both the positioning hole 311 and the positioning projection 421 running perpendicular to the first direction. This means that both the positioning hole 311 and the positioning projection 421 extend in the left-right direction. This increases the surface area on which the positioning projection 421 and the positioning hole 311 bear against each other. This improves the strength of the connection between these two and increases the structural stability of the mounting bracket. The positioning hole 311 can, of course, also be configured as a square hole in other embodiments.

With reference to 13 The support beam 201 further comprises a pin 81. The sliding wall 422 is provided with a corresponding pin hole. A section of the pin 81 protruding from the pin hole constitutes the second lug 425. It is therefore possible that, in other embodiments, the second lug 425 could also be a convex column welded to the outer side surface of the sliding wall 422. Alternatively, the sliding wall 422 is provided with a U-shaped recess, wherein the section surrounded by the U-shaped recess is bent outwards to form the second lug 425.

It will be on 1 , 2 , 7 , 8 , 14 and 15 It should be noted that in some embodiments, the outdoor air conditioning unit 91 is provided with mounting holes 911 on one side, and the mounting bracket further comprises a mounting plate 60 on the support bracket 30. The mounting plate 60 is provided with a third mounting hole 63 corresponding to the mounting hole 911, and the third mounting hole 63 is attached to the mounting hole 911 by means of a fastener. In this way, the mounting holes 911 of the outdoor air conditioning unit 91 are secured to the mounting plate 60 by means of fasteners during installation, which can improve the mounting stability of the outdoor air conditioning unit 91. The fastener can, in particular, be a screw to facilitate the installation and removal of the outdoor air conditioning unit 91. Of course, in other embodiments, the third mounting hole 63 and the mounting hole 911 can also be realized using a fastener such as a rivet or a snap fastener. Alternatively, the mounting plate 60 can be omitted and the air conditioning outdoor unit 91 can be attached directly to the support bracket 30 using a fastening element during installation.

It will be on 1 , 2 , 11 and 12 It should be noted that in some embodiments, the main support 101 further comprises a limiting bracket 20, wherein the limiting bracket 20 is arranged at an end of the support bracket 30 facing away from the mounting bracket for window frames 10, and wherein the limiting bracket 20 projects at least partially beyond an upper surface of the support bracket 30 and can bear against a side surface of the air conditioning outdoor unit 91 facing away from the mounting bracket for window frames 10. In this way, the air conditioning outdoor unit 91 can be limited by the limiting bracket 20 when it is pressed outwards on the support bracket 30. This prevents the air conditioning outdoor unit 91 from being pressed outwards too far and falling off. Of course, the limiting bracket may not be provided in other embodiments. For example, a screw is attached in a locking manner to the end of the support bracket facing away from the mounting bracket for window frames, with the head section of the screw extending beyond an upper surface of the support bracket 30 and being able to rest against a side surface of the air conditioning outdoor unit 91 facing away from the mounting bracket for window frames 10.

It will be on 1 , 2 , 11 and 12 It should be noted that in some embodiments, the mounting bracket for window frames 10 and the limiting bracket 20 are spaced apart from each other and arranged opposite each other in the first direction. The mounting bracket for window frames 10 and the limiting bracket 20 are connected to each other via the support bracket 30. At least two support beams 201 and support brackets 30 are provided, arranged in a one-to-one correspondence with each other. In this way, the main beam 101, with its frame-like structure, has high inherent strength, and the main beam 101 is supported by the multiple support beams 201, thereby improving the structural strength and stability of the main beam 101. In other embodiments, of course, only one support beam 201 may be provided.

In particular, the mounting bracket for window frames 10, the limit bracket 20, and the support bracket 30 are assembled and fixed together by screws, which not only makes it easier for the user to assemble the main support 101 but also increases the structural stability of the main support 101. Of course, in other embodiments, the mounting bracket for window frames 10, the limit bracket 20, and the support bracket 30 can also be fixed together by welding or gluing.

It will be on 1, 2, 7 to 10 As noted, in one embodiment, the mounting plate 60 allows for adjustment of the mounting position on the support bracket 30 in the first direction. Specifically, a space is created between the mounting plate 60 and the limit bracket 20, in which the outdoor air conditioning unit 91 can be placed. This allows, on the one hand, the mounting position of the outdoor air conditioning unit 91 on the main support 101 to be adjusted by changing the mounting position of the mounting plate 60 on the support bracket 30, thus enabling flexible adaptation to the actual situation at the installation site and improving the flexibility and ease of use of the mounting bracket. On the other hand, the mounting plate 60 can be moved closer to the mounting bracket for the window frame 10 before the outdoor air conditioning unit 91 is mounted. The outdoor air conditioning unit 91 can then be placed in the space provided. After the air conditioning outdoor unit 91 has been positioned, the mounting plate 60 can be moved in one direction near the limit bracket 20 so that the third mounting hole 63 is aligned with the fixing hole 911. It can be understood that during the process of positioning the air conditioning outdoor unit 91 on the main support 101, the width dimension of the The placement space in the first direction increases due to the movement of the mounting plate 60 towards the mounting bracket for the window frame 10, which is advantageous for the placement process of the air conditioning outdoor unit 91 and thus improves the ease of installation of the air conditioning outdoor unit 91. Of course, in other embodiments, it is also possible for the mounting plate 60 to be fixedly connected to the support bracket 30 or for the mounting plate 60 to be rotatably connected to the support bracket 30.

In particular, there are various ways to adjust the mounting position of the mounting plate 60 on the support bracket 30. It is referred to as... 1 , 2 and 7 As noted, in one embodiment, for example, the support bracket 30 has at least two fourth mounting holes 313, spaced apart from each other in the first direction, with the mounting plate 60 optionally mounted on one of the fourth mounting holes 313. In this way, the selective mounting with the multiple fourth mounting holes 313 makes it possible both to facilitate the positional adjustment of the mounting plate 60 and to ensure the strength of the connection between the mounting plate 60 and the support bracket 30. Of course, in other embodiments, it is also possible for the mounting plate 60 to be adjustably mounted on the support bracket 30 by means of a ball screw mechanism.

It will be on 1 , 7 , 9 and 10 As noted, in one embodiment, the support bracket 30 is provided on its underside with a first sliding groove 31, wherein a guide through-hole 314 is provided in a groove base wall of the first sliding groove 31, and the mounting plate 60 comprises a first plate section 61 and a second plate section 62, which are connected to each other. The first plate section 61 is slidably arranged in the first sliding groove 31, and the second plate section 62 penetrates the guide through-hole 314 and is provided with the third mounting hole 63. In this way, the mounting position of the mounting plate 60 on the support bracket 30 can be easily adjusted. Furthermore, the side wall of the first sliding groove 31 can act as a displacement limiter for the first plate section 61 in the left-right direction. Furthermore, the perforated wall of the guide through-hole 314 can provide a guiding effect in the first direction for the second plate section 62, thereby improving the mounting stability and the smoothness of the mounting plate 60 during sliding. In other embodiments, it is of course also possible for the first sliding groove 31 to be located on the underside of the first plate section 61 and for the support bracket 30 to be slidably arranged in the first sliding groove 31.

It will be on 7 , 9 and 10 It should be noted that in one embodiment, the mounting bracket further comprises an elastic locking projection 70, wherein the elastic locking projection 70 is arranged on the mounting plate 60 and can be elastically engaged in the fourth mounting hole 313. This simplifies the assembly, fastening, and position adjustment of the mounting plate 60 by means of the elastic locking projection 70. Of course, in other embodiments, it is also possible for the mounting plate 60 to be provided with a threaded hole or a nut corresponding to the fourth mounting hole 313, and for the fourth mounting hole 313 to be locked to the threaded hole or nut by means of the screw.

In one embodiment, the two opposing flanks of the first plate section 61 are bent downwards to form a third flange 611. The third flange 611 slides against the side wall of the first sliding groove 31, and the fourth mounting hole 313 is provided in the side wall of the first sliding groove 31. The elastic locking projection 70 is arranged on the third flange 611. In other embodiments, the fourth mounting hole 313 can, of course, also be located on the base wall of the first sliding groove 31, in which case the third flange 611 may not be provided.

In particular, the elastic ratchet protrusion exhibits 70 different structural forms. It is based on 7 and 9 As noted, in one embodiment, the elastic detent projection 70 comprises a deformation tab 71 and a convex detent column 72, wherein the deformation tab 71 includes a first tab 711, a second tab 712, and a third tab 713 connected sequentially. The first tab 711 and the third tab 713 are arranged opposite each other, and the convex detent column 72 is located on a side of the third tab 713 facing away from the first tab 711. The first tab 711 rests against the inside of the first third crimp 611, and the third tab 713 rests against the inside of the second third crimp 611. Furthermore, the second third crimp 611 is provided with a sliding hole through which the convex detent column 72 can be guided. In this way, the first plate section 61 can slide in the first sliding groove 31 to adjust its mounting position when the convex detent column 72 is retracted inwards into the fourth mounting hole 313 and the sliding hole, and then The deformation tab 71 is deformed to store energy. When the sliding hole is aligned with the other fourth mounting hole 313, the convex detent column 72 extends from the fourth mounting hole 313 under the elastic action of the deformation tab 71 to complete the relative attachment of the first plate section 61 to the first sliding groove 31. This enables both a simple structure and convenient operation. Of course, in other embodiments, the elastic detent projection 70 can also be designed as an elastically deformable positioning bead projecting from the outer side wall of the first plate section 61.

In relation to 9 It is further provided that a flank of the first plate section 61 facing away from the second third flange 611 is also bent downwards, forming a fourth flange 612. The fourth flange 612 and the first third flange 611 are spaced apart from each other in the first direction. Furthermore, the fourth flange 612 and the first third flange 611 are spaced apart from each other in the left-right direction, thereby forming a limiting channel 614. The first tab 711 is inserted into this limiting channel 614. This improves the assembly reliability of the deformation tab 71 on the first plate section 61. The fourth flange 612 may, of course, be omitted in other embodiments.

It will be on 9 and 10 As noted, in one embodiment, the opening edge of the first sliding groove 31 is bent inwards to form a limiting flange 312, and the second third flange 611 is bent in a direction close to the first third flange 611 to form a fifth flange 613. In this configuration, an outer side surface of the fifth flange 613 and a lower flank of the first third flange 611 slide against the inner side surface of the limiting flange 312. This improves the smooth operation and stability of the mounting plate 60 when sliding in the first sliding groove 31. Of course, the fifth flange 613 may be omitted in other embodiments. In this case, the lower flanks of the two third flanges 611 rest directly against the inner side surface of the limiting flange 312.

It will be on 11 to 15 As noted, in a further embodiment, the mounting plate 60 is rotatably arranged on an upper side surface of the support bracket 30 and has a first position in which a surface of the mounting plate 60 is parallel to the first direction, and a second position in which the surface of the mounting plate 60 is perpendicular to the first direction. In this way, the mounting plate 60 can be rotated into the first position before the installation of the outdoor air conditioning unit 91, thus reducing the interference caused by the mounting plate 60 during the placement process of the outdoor air conditioning unit 91 into the installation space. After the outdoor air conditioning unit 91 has been placed, the mounting plate 60 is again rotated into the second position, and the third mounting hole 63 is aligned with the mounting hole 911. This facilitates the placement process of the outdoor air conditioning unit 91 and improves the ease of installation.

It will be on 11 , 12 and 15 As noted, in a further embodiment, the mounting bracket also includes a hand-tightenable screw 83, which is attached to the main support 101 in a locking manner. The hand-tightenable screw 83 has a threaded stud that can be guided through the third mounting hole 63 and screwed into the fastening hole 911. This allows the third mounting hole 63 to be attached to the fastening hole 911 without the use of tools. In another embodiment, the head section of the hand-tightenable screw 83 is located on the top side of the main support 101 and below the mounting plate 60 in the first position. This makes it easier for the user to reach the hand-tightenable screw 83 and also allows for a more compact design of the mounting bracket. Of course, in other embodiments, it is also possible that the hand-tightenable screw 83 is not provided or that a conventional screw is used.

It will be on 15 It should be noted that in a further embodiment, the third mounting hole 63 is designed as an elongated hole such that, in the first position, it extends in a direction parallel to the first. That is, with the mounting plate 60 in the second position, the third mounting hole 63 extends in the top-bottom direction, which facilitates the alignment of the mounting hole 911 with the third mounting hole 63 in the top-bottom direction, thus improving the ease of mounting the mounting bracket with the outdoor air conditioning unit 91. Of course, in other embodiments, the third mounting hole 63 can also be designed as a round or square hole.

It will be on 1 , 2 , 4 , 6 , 7 , 11 and 12 It should be noted that in some embodiments, the mounting bracket for window frames is designed to be used. The mounting bracket 10 is provided with a clamping slot 11, and the mounting support further comprises a clamping pad 13, which is movably arranged in the clamping slot 11, wherein a clamping chamber 12 is formed between the clamping pad 13 and a slot side wall of the clamping slot 11. The clamping chamber 12 is used to clamp a window frame 923 to the window 92. In this way, it is possible to adjust the width dimension of the clamping chamber 12 by adjusting the mounting position of the clamping pad 13 on the clamping slot 11 so that it can adapt to different structures of the window frame 923. In one embodiment, it is further provided that at least two clamping pads 13 are provided, wherein the at least two clamping pads 13 are arranged at the left and right ends of the clamping slot 11. Of course, the clamping pad 13 and the clamping slot 11 may be omitted in other embodiments. Either a spring clamp is provided on the mounting bracket for window frame 10 for clamping the window frame 923, or the mounting bracket for window frame 10 is fixed to the window frame 923 by gluing or welding.

In particular, the clamping base 13 is mounted to the side wall of the clamping slot 11 by means of a threaded rod 14, and the other end of the threaded rod 14 extends from the clamping slot 11 and is fitted with a hand-tightenable screw cap 15. The user turns the hand-tightenable screw cap 15, causing the threaded rod 14 to rotate. This changes the length of the threaded rod 14 screwed into the clamping slot 11 and thus the position of the clamping base 13 within the clamping slot 11, thereby adjusting the width dimension of the clamping space 12. Of course, in other embodiments, the clamping base 13 can also include several magnetic spacers, which can optionally be inserted into the clamping slot 11.
