Description

  The present invention relates to a stand device for an in-vehicle electronic device for installing an in-vehicle electronic device having a display unit at a position such as a dashboard of a vehicle.

In a vehicle-mounted electronic device having a display unit, such as a navigation device, a radar detection device, or an ETC, a stand device is installed on an arbitrary position of the vehicle such as a dashboard so that the display unit is disposed at a position that is easy for the user to see. The in-vehicle electronic device is supported in a cantilever shape. Examples of such a stand device for an in-vehicle electronic device are shown in Patent Documents 1 to 3.
In general, a stand device for a vehicle-mounted electronic device includes a stand body and an arm on which the vehicle-mounted electronic device supported in a cantilever shape is mounted on the stand body, and the arm is at an arbitrary elevation angle with respect to the stand body. It has come to be supported. There are a screw adjustment type and a lock type as a means for supporting the arm, but the lock type is a structure in which the arm cannot be removed from the stand body and is bulky in handling. in use. The screw adjustment type is a structure in which the meshing surface on the arm side and the meshing surface on the stand main body side are meshed and fixed by fastening with a fastening member. FIG. 18 is a diagram illustrating an example of a screw-adjustable arm support structure in such a stand device for an in-vehicle electronic device.
The stand device includes a stand main body 101 and an arm 102. The stand main body 101 is formed with a pair of left and right first and second support stays 103 and 104 as a bearing portion on the stand main body side. At the base of the arm 102, a cylindrical rotation bearing 105 is formed as a bearing portion on the arm side. A first meshing surface 106 is formed on the surface of the rotary bearing 105 facing the first support stay 103. A second engagement surface 107 is formed on the inner side surface (the surface hidden in FIG. 18) of the first support stay 103. A state in which the first meshing surface 106 and the second meshing surface 107 are meshed so as to have an arbitrary elevation angle of the arm 102, and the rotation bearing 105 is disposed between the first and second support stays 103, 104 Then, the fixing screw 108 as a bolt member is inserted, the nut 109 as a nut member is rotated together with the knob 110, and both the support stays 103 and 104 are tightened from the outside, so that the both meshing surfaces 106 and 107 are brought into close contact with each other. Therefore, the arm 102 is supported by both the support stays 103 and 104.

However, in the conventional screw-adjustable arm support structure as shown in FIG. 18, the spacing between the support stays 103 and 104 is such that the rotary bearing 105 is interposed between the support stays 103 and 104 and the meshing surfaces 106 and The state where 107 is just meshed is the reference interval. That is, before the meshing surfaces 106 and 107 are meshed with each other, there is such a width relationship that if the rotational bearing 105 is inserted as it is between the support stays 103 and 104, the teeth slightly interfere with each other. Therefore, when the rotation bearing 105 is inserted between the support stays 103 and 104 from the lateral direction, both the support stays 103 and 104 (only one of them may be bent) outward to prevent the members from interfering with each other. There was no need to widen the gap slightly.
Therefore, since it is necessary to give both support stays 103 and 104 sufficient length and thinness to bend, there is a restriction on the shape and strength of both support stays 103 and 104, and both support stays 103 and 104 are made to be It was not possible to make it compact or to give sufficient strength. Moreover, since there is a restriction on the shape, it is also restricted to cooperate with other components. Further, even if the both support stays 103 and 104 are not sufficiently expanded, or even if the expansion is sufficient, the teeth of the both meshing surfaces 106 and 107 are inevitably caused by the urging force when the both support stays 103 and 104 are bent. There is also a problem that the teeth tend to hit strongly and the teeth are easily chipped or crushed. Furthermore, the user is forced to perform the troublesome task of arranging the rotary bearing 105 while expanding both the support stays 103 and 104.
The present invention has been made to solve the above-described problems, and an object of the present invention is to mount an arm on a stand main body without expanding a bearing in a screw-adjustable arm support structure. It is to provide a stand device for electronic equipment.

In order to achieve the above object, according to the first aspect of the present invention, a vehicle-mounted electronic device that is fixed to an arbitrary mounting position by a fixing means and supports a vehicle-mounted electronic device having a display unit in a cantilever shape at an arbitrary elevation angle.

A second working surface is formed on a side surface of the third bearing portion. An arm on which the electronic device is mounted; a bolt member that is inserted in this order through the movable piece member arranged in series, the first bearing portion, the third bearing portion, and the second bearing portion; And a fastening member composed of a nut member screwed near the tip of the bolt member, and the moving piece member has a first working surface that has advanced into the insertion space from the opening. The position and the first working surface are held so as to be able to move forward and backward so that the second position retracted from the insertion space can be taken, and the rotation of one of the bolt part and the nut member is restricted. The nut member is moved relatively in the head direction of the bolt part along the axial direction of the bolt part by rotating one of the other, and the moving piece member is moved by either the nut member or the head. How to advance That so as to abut pressing to the first working surface and the second working surface in the gist thereof.
In such a configuration, the stand main body is fixed to an arbitrary mounting position via the fixing means, and then the third bearing portion of the arm is disposed in the insertion space between the first and second bearing portions of the stand main body. To do. At this time, since the third bearing portion is configured to be thinner than the interval of the insertion space, no member interference occurs. Then, the moving piece member, the first bearing portion, the third bearing portion, and the second bearing portion are inserted through the bolt member in this order, and the nut member is screwed near the tip of the bolt member. Then, either one of the bolt part and the nut member is controlled while the other is rotated. By doing so, the nut member is relatively moved along the axial direction of the bolt portion in the head direction of the bolt portion. The moving piece member is moved from the opening in the insertion space direction (advancing direction) by the action of the fastening member, and the second acting surface of the third bearing portion and the first acting surface of the moving piece member are brought into contact with each other. The third bearing portion is fixed so that the arm has an arbitrary elevation angle.
Because of such a configuration, the third bearing portion can be disposed in the gap without expanding the first and second bearing portions outward, and the mounting operation becomes smooth and Problems such as chipping and crushing of members due to interference are less likely to occur. Moreover, tolerance arises in the shape of the 1st and 2nd bearing part.

According to a second aspect of the present invention, in addition to the configuration of the first aspect of the invention, the operating mechanism forming a part of the fixing means is stored behind the first and second bearing portions of the stand body. The gist.
That is, it is a more specific configuration of the stand body. Since the present invention is not limited to a shape in which the bearing portion bends as in the prior art, the bearing portion can be formed into a rigid shape integrated with the stand body. In that case, if the operation mechanism forming a part of the fixing means is stored in the stand main body, it should be stored in a position that does not interfere with the arrangement of the third bearing portion behind the first and second bearing portions. It becomes. As a result, the operating mechanism is not exposed and is functionally packaged at a position that does not interfere with the bearing portion in the stand body.

According to a third aspect of the present invention, there is provided a stand device for an in-vehicle electronic device that is fixed to an arbitrary mounting position by a fixing unit and supports an electronic device having a display unit in a cantilever shape at an arbitrary elevation angle. An arm having the first and second bearing portions, the arm on which the electronic device in which an insertion space of a predetermined interval is formed between the first and second bearing portions is mounted; and the first adjacent to the insertion space. A moving piece member disposed facing the opening formed in the bearing portion of the first bearing portion and having a first working surface formed on a surface facing the insertion space; and a thickness smaller than a predetermined interval between the insertion spaces. The third bearing portion is arranged in the insertion space, and the second bearing portion is disposed on the side surface of the third bearing portion facing the first bearing portion.

A fastening member composed of a nut member, wherein the moving piece member has a first position where the first working surface has advanced into the insertion space from the opening, and the first working surface has By being held so as to be able to advance and retract so as to be able to take the second position retracted from the insertion space, by restricting the rotation of one of the bolt part and the nut member and rotating the other The nut member is moved relatively in the head direction of the bolt portion along the axial direction of the bolt portion, and the moving piece member is pushed in the advance direction by either the nut member or the head to move the first member. Working surface and the above That the second working surface and so as to abut the gist thereof.
In such a configuration, the stand main body is fixed to an arbitrary mounting position via the fixing means, and then the third bearing portion of the stand main body is disposed in the insertion space between the first and second bearing portions of the arm. To do. At this time, since the third bearing portion is configured to be thinner than the interval of the insertion space, no member interference occurs. Then, the moving piece member, the first bearing portion, the third bearing portion, and the second bearing portion are inserted through the bolt member in this order, and the nut member is screwed near the tip of the bolt member. Then, either one of the bolt part and the nut member is controlled while the other is rotated. By doing so, the nut member is relatively moved along the axial direction of the bolt portion in the head direction of the bolt portion. The moving piece member is moved from the opening in the insertion space direction (advancing direction) by the action of the fastening member, and the second acting surface of the third bearing portion and the first acting surface of the moving piece member are brought into contact with each other. The third bearing portion is fixed so that the arm has an arbitrary elevation angle.
Because of such a configuration, the third bearing portion can be disposed in the gap without expanding the first and second bearing portions outward, and the mounting operation becomes smooth and Problems such as chipping and crushing of members due to interference are less likely to occur. Moreover, tolerance arises in the shape of the 1st and 2nd bearing part.

In the above description, “restricting the rotation of one of the bolt part and the nut member and turning the other one” means that the bolt part is turned to advance the moving piece member in the retracted position in the insertion space direction. It means that any of them can be rotated even if the nut member is rotated or the nut member is rotated. Further, when one side is rotated, the rotation of the fastening member on the side that is not the fastening member that is always rotated is required because the rotation is not performed unless the other rotation is restricted.
The movable piece member has a first working surface, and the first working surface is configured to be able to take a first position where the first working surface is advanced from the through hole into the insertion space and a second position which is retracted from the insertion space. If it does, the shape does not matter.
The first and second working surfaces are not particularly limited as long as they can hold the arm in a cantilever shape by contacting them, that is, if they have a surface shape that does not rotate the third bearing portion. Not. For example, a frictional action or an uneven engagement action may be used, or a combination thereof may be used. It is preferable to use a meshing surface formed from a large number of teeth such as serrations formed on a flat surface, such as a serrated surface that engages with each other and prevents rotation, for example, serrations.

In the invention of claim 4, in addition to the structure of any one of claims 1 to 3, the gist of the invention is that a dropping prevention means for preventing the moving piece member from dropping to the insertion space side is provided. To do.
With such a configuration, when the third bearing portion does not exist in the insertion space, the moving piece member is prevented from dropping out from the through hole in the insertion space direction.

According to a fifth aspect of the invention, in addition to the configuration of the fourth aspect of the invention, the movable piece member is housed in a housing space formed in the first bearing portion, and advances and retreats in the housing space. And
Accordingly, the movable piece member is held without being exposed in the first bearing portion.

Hereinafter, a stand device for an in-vehicle electronic device according to an embodiment of the present invention will be described with reference to the drawings.
Example 1
As shown in FIGS. 1 to 3, for example, a stand device (hereinafter simply referred to as a stand device) 1 for a radar detection device with a navigation function is separable from a stand body 2 and a stand body 2 as an in-vehicle electronic device. The arm 3 is provided as a component. First, the stand body 2 will be described.
As shown in FIGS. 4 to 9, 13, etc., the stand main body 2 is a molded product of hard plastic and hangs at a moderate angle toward the housing portion 4 and the periphery disposed at the lower position of the housing portion 4. And a thin-walled base portion 5. As shown in FIGS. 4A to 4C, the housing portion 4 is a trapezoidal outer shape chamfered at a corner in a side view and a hollow case body having a square outer shape in a front view, A center portion in the viewing direction (viewing direction in FIG. 4C) is hollowed out to form a pair of left and right first and second bearing portions 6 and 7. A wall portion 8 that is curved outwardly is formed in the back of the recessed space between the bearing portions 6 and 7. As shown in FIGS. 2 and 4 (c), the outer side surfaces 4a and 4b of the housing part 4 and the inner side surfaces 6a and 7a of the bearing parts 6 and 7 are configured in a plane parallel to each other. A space defined by the inner side surfaces 6a, 7a of both the bearing portions 6, 7 and the wall portion 8 is defined as an insertion space S.

  As shown in FIGS. 4A, 5, 6, and the like, a through hole 10 having a circular cross-section communicating in the left-right direction is formed in the first bearing portion 6. The through hole 10 includes a first opening 11 that opens to the insertion space S side and a second opening 12 that opens to the outside of the first bearing portion 6. A detent surface 13 having a regular octagonal cross-sectional shape is formed on the inner peripheral surface of the through hole 10 near the first opening 11. A connection surface between the rotation preventing surface 13 and the inner peripheral surface of the through hole 10 is a discontinuous step portion 13a. A small recess 14 cut out in the radial direction is formed on the inner peripheral surface of the through hole 10 near the second opening 12. A substantially rhombic mounting recess 15 is formed on the outer surface 4 a of the housing portion 4 facing the second opening 12 so as to surround the periphery of the second opening 12.

As shown in FIG. 7, an arm stopper 17 as a moving piece member and a hexagonal nut 18 as a nut member are disposed in the through hole 10, and a second lid serving as an entrance to the through hole 10 by an outer lid 19. The opening 12 is blocked. As shown in FIGS. 11A to 11C, the hard plastic arm stopper 17 is a hollow cup-shaped member, and a bolt hole 23 is formed in the front wall 22. The front wall 22 is formed with a first engagement surface 24 made of serrations arranged in a ring shape so as to surround the bolt hole 23. An engagement surface 25 formed in a regular octagonal cross-sectional shape is formed on the outer periphery of the arm stopper 17. A flange 26 having the same diameter is formed at the rear end edge of the arm stopper 17 over the entire circumference. A convex portion 26 a protruding outward is formed on a part of the flange 26.
A nut housing portion 27 having a regular hexagonal cross-sectional shape is formed on the inner peripheral surface of the arm stopper 17. A hexagonal nut 18 shown in FIG. 9 is disposed in the nut accommodating portion 27, and the hexagonal nut 18 is engaged with the nut accommodating portion 27 on the outer peripheral surface thereof. Accordingly, the hexagon nut 18 and the arm stopper 17 are integrally rotated in the circumferential direction.
The arm stopper 17 is positioned in the through hole 10 so that the convex portion 26a corresponds to the small concave portion 14 from the second opening 12 direction, that is, in a state in which the direction (phase) in the circumferential direction when inserting is positioned. Is inserted into the through-hole 10 from the meshing surface 24 side and accommodated. The hexagon nut 18 is accommodated in the through hole 10 together with the arm stopper 17.
The outer lid 19 is attached to the mounting recess 15 formed on the outer surface 4 a of the housing part 4 with the screw 29 in a state where the arm stopper 17 (and the hexagon nut 18) is accommodated in the through hole 10. The substantially rhombus-shaped outer lid 19 corresponding to the mounting recess 15 is formed with a pressing projection 19a on the inner surface, that is, the surface facing the through hole 10 side.

  When the arm stopper 17 is disposed in the through hole 10, the outer peripheral engagement surface 25 is engaged with the anti-rotation surface 13 and the rotation in the circumferential direction is restricted. Therefore, the rotation of the hexagon nut 18 in the circumferential direction is also restricted. The entire width (axial length) of the arm stopper 17 is shorter than the entire length of the through hole 10, and therefore the arm stopper 17 is loosely fitted in the through hole 10 so as to be able to advance and retreat in the front-rear direction (left and right direction in FIG. 7). Become. Furthermore, the axial length of the engagement surface 25 of the arm stopper 17 (the length to the side surface of the flange 26) is greater than the axial length of the anti-rotation surface 13 (the length to reach the step portion 13a). It is structured long. Therefore, when the arm stopper 17 advances in the insertion space S direction, the first meshing surface 24 is exposed in the insertion space S direction, and when the arm stopper 17 moves backward, the first meshing surface 24 enters the through hole 10. Will die. The arm stopper 17 is prevented from advancing further by the flange 26 coming into contact with the stepped portion 13 a in the through hole 10, and can be moved rearward until it interferes with the pressing protrusion 19 a of the outer lid 19.

The head 35 has a disk-like plate shape, and a knob portion 35a is formed at a position along the diameter at the center of the outer surface. The diameter of the head 35 corresponds to the diameter of the housing recess 31 (slightly smaller). As shown in FIG. 7, the head 35 is accommodated in the accommodating recess 31 so as to be freely rotatable in a state where the male screw main body 34 of the angle adjusting screw 33 is inserted into the bolt hole 30.
As shown in FIGS. 1 and 3, a part of the head 35 has a part that is always exposed from the housing recess 31 that is partly cut away, and the exposed part of the head 35 is a corner part of the stand body 2 in a side view. Since it matches the shape of the chamfered shape, the design of the overall shape of the stand body 2 is coordinated in a side view. In addition, the outer surface of the head 35 is substantially the same height as the outer surface 4b of the housing part 4 in the front view (slightly higher than the outer surface 4b). Are coordinated.
As shown in FIG. 6, the male screw body 34 is long enough to reach a position where the tip does not contact the outer lid 19 in the through hole 10 on the second bearing portion 7 side in a state where the head 35 is accommodated in the accommodating recess 3. It is said.

As shown in FIG. 13, the housing part 4 is placed on the base part 5. The base unit 5 includes a plurality of claws 40 (only one is shown in FIG. 13) and a support column 41. The housing part 4 engages the claws 40 with the engaging grooves 42 formed in the interior of the housing part 4 in a scattered manner, and the upper wall 4c of the housing part 4 and the upper part of the column 41 are joined together by screws (not shown). The base portion 5 is fixed by tightening. A drive pin 43 is disposed at the center position of the base portion 5 so as to be movable up and down. The lower end side of the drive pin 43 is connected to a suction cup 44 made of silicone rubber so as to cover the lower surface of the base portion 5. A coil spring 45 is disposed between the base portion 5 and the suction cup 44 so as to surround the drive pin 43.
A lever 47 is rotatably connected to the upper position of the drive pin 43 by a rotation shaft 46. In the lever 47, the cam shaft 47a as the drive transmission portion is located near the rotation shaft 46, and the pressing portion 47b is located near the tip. The lever 47 as a whole is a lever device having the rotation shaft 46 as a fulcrum, the cam 47a as an action point, and the pressing portion 47b as a power point. The pressing portion 47 b is exposed from the exposure port 48 at the rear of the housing portion 4. The portion exposed above the base portion 5 of the drive pin 43 and the cam 47a of the lever 47 are housed inside the housing portion 4 that is located behind the first and second bearing portions 6 and 7 and the insertion space S. .
With this configuration, as shown in FIG. 13, the lever 47 is moved from the position of the upper solid line to move to the position of the virtual line so that the drive pin 43 moves upward.
