Detailed Description

Exemplary embodiments that embody features and advantages of the invention are described in detail below in the specification. It is to be understood that the invention is capable of other embodiments and that various changes in form and details may be made therein without departing from the scope of the invention and the description and drawings are to be regarded as illustrative in nature and not as restrictive.

As shown in fig. 2, the present invention mainly provides a television set. The television comprises a stainless steel frame 1, a display screen 2 and a back plate 3. The stainless steel frame 1 is used for covering a display screen 2 of a television. The display screen 2 may be a liquid crystal display screen or an OLED display screen. The back plate 3 locks and fixes the display screen from the back of the display screen 2.

In a preferred embodiment, the stainless steel frame 1 comprises a U-shaped frame body 11 and a strip-shaped lower frame 12, as shown in fig. 2. The stainless steel frame body 11 is detachably connected with the stainless steel lower frame 12.

The frame 11 is a U-shaped integral structure, and the frame 11 includes three frames 13. The three frames 13 are spliced into a U-shaped structure. Specifically, the housing 11 includes a front frame 132, a side frame 131, and a back frame 133 provided on the front side of the display screen. The front frame 132 and the back frame 133 are respectively connected to both sides of the side frame 131. The side frame 131, the front frame 132 and the back frame 133 form a receiving groove 14 for receiving the display screen. The three sides of the display screen 2 are respectively and correspondingly accommodated in the accommodating grooves 14 of the three frames 13. The lower frame 12 is provided at the U-shaped opening of the frame 11. The two ends of the lower frame 12 are respectively connected with the two free ends of the frame body 11 in a splicing manner, and are spliced with the frame body 11 to form a rectangular frame structure for wrapping the periphery of the display screen 2.

The lower frame 12 includes a front panel 121 positioned at the front side of the display screen. The front plate 121 has insertion pieces 126 at both ends thereof. One side surface of the inserting sheet 126 is an abutting surface 129, the abutting surface 129 is fixedly connected with the inner side surface of the front plate 121, and the inner side surfaces at two free ends of the front frame 132 are abutted with the abutting surfaces 129 of the corresponding inserting sheets 126.

Compared with a television adopting a four-section splicing mode, the television of the embodiment can avoid the problems of offset and flash seams generated at two top corners on the stainless steel frame 1, and the appearance quality of the television can be controlled easily. Further, since the tab 126 has a planar structure, one side surface of the tab 126 serves as an abutment surface 129. The inner side surface of the front plate 121 and the inner side surface of the front frame 132 are both in contact with the contact surface 129, and the contact surface 129 of the male tab 126 serves as a common reference for assembling the front frame 132 of the frame body 11 and the front plate 121 of the lower frame 12, so that the offset generated at the joint between the lower frame 12 and the frame body 11 during assembling is ensured within a control range.

Moreover, the U-shaped frame body 11 structure forms half-surrounding assembly on the display screen 2, and then the lower frame 12 and the frame body 11 are smoothly spliced and assembled, so that the assembly of the television can be completed, and the assembly efficiency is improved.

Moreover, because the stainless steel material has high strength and small deformation, the installation strength can be achieved only by locking the back frame and the back plate 3 by back screws. Other structural parts do not need to be additionally arranged, the front frame of each frame 13 of the frame body 11 does not need to be connected with the display screen 2, the front frame can be narrowed as far as possible, and the effect of the narrow frame 13 is achieved.

Moreover, because the strength and hardness of the stainless steel are much higher than those of the aluminum alloy, the thickness of the material used by the stainless steel frame 1 is smaller than that of the aluminum alloy material when the same strength is ensured, and the ultrathin effect of the television can be realized.

As shown in fig. 3, in the present embodiment, the frame 11 is formed by stamping or rolling a bar-shaped material having an accommodating groove 14 for accommodating the display panel 2. The forming mode of stamping or rolling ensures the forming effect of the frame body 11, and has simple operation and lower cost. Accordingly, each of the frames 13 has a side frame 131, a front frame 132 and a back frame 133 connected to both sides of the side frame 131, respectively. The side frame 131, the front frame 132 and the back frame 133 form a receiving groove 14 for receiving the display screen 2. The three sides of the display screen 2 are respectively and correspondingly accommodated in the accommodating grooves 14 of the three frames 13.

As shown in fig. 2, two bending portions of the front frame 132 and two bending portions of the back frame 133 are both provided with slits 134. The slits 134 allow the elongated stainless steel section to be bent. The slit 134 is a linear slit in the processing, and does not affect the sealing property and the flatness of the frame body 11, and therefore does not affect the appearance quality of the frame body 11. It is understood that the slits 134 may be formed by laser cutting, and the slits 134 may facilitate bending of the stainless steel frame 11, and facilitate stress release of the front frame 132 and the back frame 133 at the bending positions.

The side frame 131 is rounded at two bent portions. Thus. The frame body 11 is of an integrated structure at two bending positions, is not required to be spliced and fixed externally, is not influenced by subsequent assembly and the appearance precision of the display screen 2, and can ensure the appearance quality of the two corners.

As shown in fig. 3, the width of the back frame 133 is smaller than that of the front frame 132. Since the frame body 11 has high strength, the back frame 133 only needs to be connected to the fastening member 4. The back frame 133 has a small width, so that the overall weight of the stainless steel frame 1 can be reduced, and the structure can be simplified.

Specifically, in the present embodiment, a step 31 is provided at the edge of the back plate 3. The step 31 performs a step-down process on the edge of the back plate 3. The step 31 is connected to the back frame 133 of the bezel 13. The step portion 31 is accommodated in the accommodating groove 14 and is overlapped with the back frame 133, so that the fastening member passes through the step portion 31 and the back frame 133 to realize fastening connection. Through the face descending treatment of the step part 31, the height between the surface of the back plate 3 and the surface of the fastening piece 4 can be within 0.2mm, so that the surface of the fastening piece 4 and the back plate 3 can be approximately kept in the same plane, and the flatness of the back face of the television is ensured.

Referring to fig. 3, specifically, the folding angle of the step portion 31 is a rounded angle. There is a gap L1 between the edge of the back frame 133 and the rounded corner of the step part 31 of the back panel 3 and the gap L1 is maintained at 0.3 mm. The abrasion of the backboard 3 mould in the mass production process is avoided, the round angle of the step part 31 is enlarged, and the interference is caused in the assembling process.

A gap L2 is formed between the side frame 131 of each frame 13 and the side surface of the display panel 2. That is, a gap is formed between the bottom of the accommodating groove 14 and the side surface of the display screen 2. Also, the gap L2 is maintained between 0.3 and 0.5 mm. The gap L2 can adapt to the shape error of the display screen 2, and avoids the damage to the display screen 2 due to the larger hardness of the stainless steel frame 1.

The lower frame 12 is provided at the U-shaped opening of the frame 11. The two ends of the lower frame 12 are respectively connected with the two free ends of the frame body 11 in a splicing manner, and are spliced with the frame body 11 to form a rectangular frame structure for wrapping the periphery of the display screen 2. Specifically, two ends of the lower frame 12 are connected with two free ends of the frame 11 by welding.

Referring to fig. 4, the lower frame 12 includes a body 122, a connecting plate 124 and an inserting piece 126. The lower frame 12 uses a stamped sheet metal material. In this embodiment, the lower frame 12 is decomposed into three different parts, which are processed separately, thereby reducing the processing difficulty. Then, the lower frames 12 are combined by welding, and different functions of the lower frames 12 are realized respectively.

Referring to fig. 4 and 5, the main body 122 includes two front plates 121 and two side plates 123 perpendicular to each other. The front plate 121 and the side plates 123 are arranged in an L shape, and the width of the front plate 121 is greater than that of the side plates 123. The body 122 is made of a stainless steel sheet with a thickness of 0.5mm-0.6mm, and the body 122 is formed by a die in a stamping mode.

The front plate 121 is located on the front side of the display screen 2. The front plate 121 is used for abutment of the front surface of the display screen 2 to be fixed from the front side of the display screen 2. It will be appreciated that the front plate 121 is provided with a projection for holding the display screen 2. The projections cooperate with the structure of the display 2 to hold the display 2 firmly against the front plate 121.

Because the lower frame 12 is made of stainless steel material, the rigidity of the stainless steel material is stronger. The front plate 121 of the lower frame 12 has no connection and matching requirement with the display screen 2, and only the display screen 2 needs to be supported on the front plate 121. Therefore, the width of the front panel 121 can be narrowed as much as possible, and a narrow bezel effect is achieved.

As shown in fig. 6, the television set in this embodiment further includes a sealing member 6. The seal 6 is pressed between the front plate 121 and the liquid crystal glass 7 of the display screen 2. And, the sealing member 6 is arranged near the outer edge of the front plate 121 to seal the inner cavity formed by the stainless steel frame 1 and the display screen 2 of the television, so as to prevent dust and impurities from entering the inner cavity and damaging the display screen 2. The seal 6 presses the liquid crystal glass 7 to prevent the liquid crystal glass 7 from moving.

It will be appreciated that the seal 6 may be a rubber gasket or a plastic ring or the like. The sealing member 6 can play a role in sealing a gap between the display screen 2 and the stainless steel frame 1, and plays a role in compressing the liquid crystal glass 7 and reinforcing the display screen 2.

As shown in fig. 6, the side plate 123 is used for fixedly connecting with the rear case 8 of the television. Specifically, the side of the side plate 123 far away from the front plate 121 is provided with a hook structure 125. The rear shell 8 is provided with a clamping groove. The hook structure 125 is connected to the slot. It is understood that the hook structure 125 is formed by welding together two layers of sheet metal. The hook structure 125 and the slot of the rear housing 8 are in interference fit with each other, so as to ensure tight combination. Because the rear shell 8 of the television is fixedly arranged on the back plate 3 of the display screen 2, the side plate 123 is fixedly connected with the rear shell 8, and a pretightening force can be given to the lower frame 12.

As shown in fig. 4 and 5, the connecting plate 124 is provided with a folded edge 127 along the longitudinal direction thereof. The folding edge 127 is fixedly connected with one side surface of the front plate 121 close to the side plate 123, and the connecting plate 124 is used for fixedly connecting with the display screen 2. Specifically, the flange 127 is welded to the side plate 123. The connection plate 124 corresponds to the lower side of the display screen 2 and the connection plate 124 is used to carry the lower side of the display screen 2. Therefore, the frame 11 and the lower frame 12 can fix the four side plates 123 of the display panel 2. The thickness of the stainless steel material of the connection plate 124 is 0.8mm to 1mm depending on the size of the television.

As shown in fig. 7, the connecting plate 124 is provided with a sink 128. The bottom of the sinking groove 128 is provided with a through hole, and the fastener passes through the through hole to be connected with the side surface of the display screen 2. The side of display screen 2 is the installation face of display screen 2, and the bottom of heavy groove 128 is inconsistent with the side of display screen 2, through fastener fastening connection display screen 2 and connecting plate 124. It is understood that a plurality of sinking grooves 128 are formed on the connecting plate 124, and the plurality of sinking grooves 128 can reinforce the display screen 2 and the lower frame 12.

As shown in fig. 5, the inserting pieces 126 are fixedly arranged at two ends of the front plate 121 along the length direction, and are fixedly arranged at one side of the front plate 121 close to the connecting plate 124. Specifically, the tab 126 is stainless steel. Tabs 126 are welded to the inside of front panel 121. And insert 126 is on the other side of web 124 relative to flap 127. As shown in fig. 8, the side of the insert 126 protruding from the front plate 121 is an abutting surface 129. The contact surface 129 is for contact with the front frame 132 of the housing 11.

As shown in fig. 9 and 10, in the present embodiment, the first bevel structures 15 are provided at both ends of the front plate 121. The tab 126 is provided on the inner side of the first angled structure 15. The insert tab 126 is a rectangular tab and one side of the insert tab 126 protrudes from the edge of the front panel 121. Therefore, the free ends of the frame 11 are provided with second bevel structures 16. The inner side surface of the second angled structure 16 can abut against the abutment surface 129.

As shown in fig. 10, a portion of the tab 126 is disposed on the inner side of the first angled structure 15 and another portion is disposed on the inner side of the second angled structure 16. Because the insert 126 is of a planar structure, the insert 126 serves as a common reference for assembling the frame body 11 and the lower frame 12, and the step difference generated when the lower frame 12 and the frame body 11 are assembled is ensured to be within a control range. Moreover, the design thickness of the inserting sheet 126 is 0.3-0.4mm, which does not affect the thickness and installation requirements of the lower frame 12. After the frame body 11 and the lower frame 12 are assembled, the inner side surfaces of the frame body 11 and the lower frame 12 are both attached to the surface of the inserting piece 126, so that the outer side surfaces of the frame body 11 and the lower frame 12 can be ensured to be positioned on the same horizontal plane.

Moreover, when the lower frame 12 is turned by an external force, the insert 126 is driven to turn, and the insert 126 is tightly attached to the inner side wall of the frame body 11 and is pressed by the inner side wall of the U-shaped frame body 11, so that the external force applied to the lower frame 12 is offset, and the problem of offset between the lower frame 12 and the frame body 11 is solved.

Therefore, the first bevel structure 15 and the second bevel structure 16 are matched and spliced with each other, so that the frame body 11 and the lower frame 12 are butted.

And, the width of the first bevel structure 15 at both ends of the front plate 121 is smaller than the width of the front plate 121, the both ends of the front plate 121 form the straight portions 151. Accordingly, at the two free ends of the U-shaped structure of the frame 11, the length of the side frame 131 is greater than that of the front frame 132, and the top end of the side frame 131 protrudes from the front frame 132. When the first bevel structure 15 of the front plate 121 and the second bevel structure 16 of the frame 11 are mated and spliced with each other, the straight portion 151 of the front plate 121 is connected to the top end of the side frame 131 of the frame 11 near the side edge of the front frame 132. The binding ends of the side plates 123 limit the straight portion of the front plate 121, so as to prevent the first bevel structure 130 and the second bevel structure 140 from being dislocated along the inclined plane, thereby improving the stability of the joint between the lower frame 12 and the frame 11.

Referring to fig. 9 and fig. 7, the free ends of the back frames 131 on both sides of the U-shaped frame 11 are respectively provided with the locking protrusions 134, and the two ends of the connecting plate 124 of the lower frame 12 are respectively provided with the locking portions 120. The locking protrusions 134 and the locking portions 120 are engaged with each other, so that the back frame 131 is engaged with the connecting plate 124, thereby enhancing the connection strength between the frame body 11 and the lower frame 12.
