Description

Technical Field

[0001] This application relates to a backplate shape correction device. Background Technology

[0002] With the rapid development of automotive electronics technology, automotive displays have gradually become a core component of in-vehicle information interaction. Their functions include not only displaying basic information such as vehicle speed and navigation, but also providing audio-visual entertainment and driver assistance features. As a crucial component of the display screen, the back panel not only needs to support the internal structure but also ensures the required dimensional accuracy to meet installation requirements and ensure precise fit with other components. However, due to factors such as manufacturing processes and transportation vibrations, the sidewalls of the back panel may experience flatness issues, thus affecting the assembly of the back panel. Utility Model Content

[0003] The purpose of this invention is to provide a backplate shape correction device with a simple structure and easy operation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a backplate shape correction device, comprising:

[0005] The substrate has a bottom wall supporting the back plate and two abutting walls extending upward from the bottom wall, the two abutting walls intersecting and perpendicular to each other in the horizontal direction;

[0006] A correction mechanism is placed on the substrate and positioned relative to one of the supporting walls;

[0007] A positioning mechanism is disposed outside the calibration mechanism and abuts against the calibration mechanism;

[0008] The correction mechanism includes a first plate and a second plate disposed opposite to each other, a height-moving member clamped between the first plate and the second plate, and a fastener mounted on the height-moving member. The outer sidewalls of the first plate and the second plate respectively abut against the sidewalls of the positioning mechanism and the back plate. The inner sidewalls of the first plate and the second plate form an inverted trapezoidal groove. The height-moving member is located in the inverted trapezoidal groove. A T-shaped through hole is formed on the height-moving member. A first threaded hole corresponding to the T-shaped through hole is formed on the base plate. The fastener passes through the T-shaped through hole to be threadedly connected to the first threaded hole.

[0009] Furthermore, the height-moving member has an abutting surface that abuts against the inner sidewall of the first plate and the inner sidewall of the second plate, and the abutting surface is a downward-facing slope.

[0010] Furthermore, the first plate and the second plate are respectively recessed inward on the inner sidewall to form a side wing groove, and the height moving member protrudes outward from the abutting surface to form a side wing portion, which is accommodated in the side wing groove.

[0011] Furthermore, the central axis of the side wing intersects with and is perpendicular to the axis of the T-shaped through hole.

[0012] Furthermore, the first plate extends outward from its end to form a folding portion, which abuts against the side wall of the back plate.

[0013] Furthermore, an elastic strip is affixed to the folding section.

[0014] Furthermore, the positioning mechanism includes a positioning block and a bolt. The positioning block has a square through hole, and the substrate has a second threaded hole. The bolt is inserted into the square through hole and threadedly connected to the second threaded hole. The extending direction of the square through hole is the same as the extending direction of the opening of the inverted trapezoidal groove in the horizontal direction.

[0015] Furthermore, a relief groove is formed at the junction of the two supporting walls.

[0016] Furthermore, the bottom wall has a plurality of recesses, and ball bearings are disposed in the recesses, the ball bearings being located below the position for placing the back plate.

[0017] The beneficial effects of this utility model are as follows: This application achieves the shaping of the back plate side by having the two sides of the back plate abut against the two abutting walls respectively, and then adjusting the height moving part of the correction mechanism to move downward so that the first plate can further push against the back plate, so that the side wall of the back plate moves towards the abutting wall opposite to the first plate, thereby achieving the shaping of the back plate side.

[0023] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Please see Figure 1 The backplate shape correction device 10 shown in one embodiment of this application includes a base plate 1, a correction mechanism 2, and a positioning mechanism 3. The base plate 1 has a bottom wall 11 supporting the backplate 20 and two abutment walls 12 extending upward from the bottom wall 11. The two abutment walls 12 intersect and are perpendicular to each other in the horizontal direction. A relief groove 13 is recessed at the intersection of the two abutment walls 12. The relief groove 13 can reduce interference at the intersection of the backplate 20 and the abutment walls 12, and avoid edge deformation or damage to the backplate 20.

[0025] The correction mechanism 2 is placed on the base plate 1 and is positioned opposite one of the supporting walls 12. The positioning mechanism 3 is disposed outside the correction mechanism 2 and abuts against the correction mechanism 2. The correction mechanism 2 includes a first plate 21 and a second plate 22 disposed opposite to each other, a height-moving member 23 clamped between the first plate 21 and the second plate 22, and a fastener 24 mounted on the height-moving member 23. The outer sidewalls of the first plate 21 and the second plate 22 abut against the positioning mechanism 3 and the sidewall (not labeled) of the back plate 20, respectively. The inner sidewalls of the first plate 21 and the second plate 22 form an inverted trapezoidal groove 25. The height-moving member 23 is located within the inverted trapezoidal groove 25. A T-shaped through hole 26 is formed on the height-moving member 23. A first threaded hole (not shown) corresponding to the T-shaped through hole 26 is formed on the base plate 1. The fastener 24 passes through the T-shaped through hole 26 to be threadedly connected to the first threaded hole. The fastener 24 can specifically be a bolt with an internal hexagonal hole at the top.

[0026] In this embodiment, the height-moving component 23 has a contact surface (not labeled) that abuts against the inner sidewall of the first plate 21 and the inner sidewall of the second plate 22. The contact surface is a downward-facing inclined surface that fits against the inner sidewall. By setting it in this way, a more stable and uniform lateral force transmission is achieved, stress concentration is reduced, and the height-moving component 23 moves more smoothly in height.

[0027] By pressing the two sides of the back plate 20 against the two abutting walls 12 respectively, and then adjusting the height moving part 23 of the correction mechanism 2 to move downward so that the first plate 21 can further push against the back plate 20, the side of the back plate 20 moves towards the abutting wall 12 opposite to the first plate 21, thereby shaping the side of the back plate 20.

[0028] The operation of the back panel shape correction device 10 will be described in detail below. For ease of description, the abutment wall 12 parallel to the height moving member 23 is defined as the first abutment wall 121, and the other abutment part is defined as the second abutment wall 122. The specific operation of the back panel shape correction device 10 is as follows:

[0029] Step A: Place the back plate 20 on the bottom wall 11, with the side wall to be shaped facing the first supporting wall 121, and the other side wall abutting against the second supporting wall 122. There is a small distance between the side to be shaped and the first supporting wall 121.

[0030] Step B: Place the correction mechanism 2 on the bottom wall 11, and install the fastener 24 through the T-shaped through hole 26 into the first threaded hole. At this time, the height moving part 23 is not in complete contact with the bottom wall 11, and there is an adjustment distance between it and the bottom wall 11 required for subsequent shaping. The second plate 22 is attached to the side wall of the back plate 20.

[0031] Step C: Install the positioning mechanism 3 on the bottom wall 11. At this time, there is also a certain distance between the positioning mechanism 3 and the first plate 21. This distance is approximately the same as the distance between the side and the first abutting wall 121.

[0032] Step D: Align the screwdriver with the hexagonal socket of the bolt, rotate the screwdriver to drive the height-moving component 23 downward. During this downward movement, the height-moving component 23 pushes the first plate 21 and the second plate 22 towards the positioning mechanism 3 and the side wall of the back plate 20, respectively. Thus, the second plate 22 applies a pushing force to the side wall of the back plate 20, gradually pushing it against the first abutting wall 121. Since there was initially a small gap between the back plate 20 and the first abutting wall 121, as the pushing force increases, the side wall of the back plate 20 gradually moves until it is completely flush with the first abutting wall 121. As the pushing force increases, uneven parts (such as bulges) on the side wall of the back plate 20 will be pushed against the abutting wall 122, thereby achieving the shaping purpose. Simultaneously, since the other side wall of the back plate 20 abuts against the second abutting wall 122...

[0033] Therefore, while the second plate 22 pushes the back plate 20 toward the first supporting wall 121, it can also play a role in moving and shaping the overall frame of the back plate 20.

[0034] In this embodiment, the first plate 21 and the second plate 22 are respectively recessed inward on their inner sidewalls to form side wing grooves 211. The height-moving member 23 protrudes outward from the abutment surface to form a side wing portion 231. The side wing portion 231 is accommodated in the side wing groove 211. The cooperation between the side wing portion 231 and the side wing groove 211 can prevent the height-moving member 23 from misaligning or swaying during its up-and-down movement. The central axis of the side wing portion 231 intersects with and is perpendicular to the axis of the T-shaped through hole 26. This arrangement ensures that the height-moving member 23 is subjected to uniform force, reducing tilting or offset caused by uneven force.

[0035] In an alternative embodiment, the first plate 21 may be further bent outward from its end to form a folding portion (not shown). The folding portion abuts against the side wall of the back plate 20. During the side shaping process of the back plate 20, the folding portion abuts against the side wall that is not abutting against the supporting wall 12, thereby enhancing the clamping force of the correction device on the back plate 20 and preventing the back plate 20 from loosening or shifting during the correction process. In this embodiment, to avoid scratching or damage when the folding portion contacts the back plate 20, an elastic strip is affixed to the folding portion.

[0036] In this embodiment, the positioning mechanism 3 includes a positioning block 31 and a bolt 32. The positioning block 31 has a square through hole 311, and the base plate 1 has a second threaded hole (not shown). The bolt 32 is inserted into the square through hole 311 and threadedly connected to the second threaded hole. The extension direction of the square through hole 311 is the same as the extension direction of the horizontal opening of the inverted trapezoidal groove 25, that is, the same as the extension direction of the second abutment wall 122. Through the cooperation of the square through hole 311 and the bolt 32, the adjustment range of the positioning mechanism 3 is increased, which facilitates the quick adjustment of the overall position of the calibration device and adapts to back plates 20 of different sizes.

[0037] In some embodiments, the bottom wall 11 has a plurality of recesses (not shown) formed inward, and ball bearings (not shown) are disposed in the recesses. The ball bearings are located below the position for placing the back plate 20. By using freely rotating ball bearings, the contact points are adjusted with the movement of the back plate 20 during the calibration process, thereby reducing the friction between the back plate 20 and the surface of the substrate 1, achieving flexible support, and protecting the surface of the back plate 20.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
