[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1 As shown, this utility model provides a testing fixture for automotive electronics, including a base 10. An angle adjustment component 2 is provided on the top of the base 10. A rotating disk 11 is provided on the top of the angle adjustment component 2. Four rectangularly distributed support columns 12 are fixedly connected to the top of the rotating disk 11. A placement plate 13 is fixedly connected to the top of the four support columns 12. Shape adaptive fixing components 3 are provided on the upper and lower sides of the placement plate 13.

[0024] The base 10, as the basic support component of the entire tooling, is made of high-strength aluminum alloy, which has good stability and durability. Its top is equipped with an installation angle adjustment component 2 and a shape self-adaptive fixing component 3, which can provide stable fixing and multi-angle testing conditions for automotive electronic components.

[0025] like Figure 2 As shown, the angle adjustment assembly 2 includes a drive chamber 20. The bottom of the drive chamber 20 is fixedly connected to the top of the base 10. A motor 21 is fixedly connected to the left side of the front side wall of the drive chamber 20. A worm gear 22 is rotatably connected to the left side of the inner walls of the front and rear sides of the drive chamber 20. The output end of the motor 21 passes through the interior of the drive chamber 20 and is fixedly connected to the worm gear 22.

[0026] like Figure 2 As shown, a worm gear 23 is meshed with the right side of the worm 22. A rotating shaft 24 is fixedly connected inside the worm gear 23. The rotating shaft 24 is rotatably connected to the middle of the upper and lower inner walls of the drive chamber 20. The top of the rotating shaft 24 extends through to the top of the drive chamber 20 and is fixedly connected to the rotating disk 11.

[0027] When the angle of the clamped automotive electronic component needs to be adjusted, motor 21 is powered on and started. The output shaft rotates, driving worm 22 to rotate. Worm 22 meshes with worm wheel 23. Due to the large transmission ratio and self-locking characteristics of worm gear transmission, the rotation of worm 22 drives worm wheel 23 to rotate. When worm wheel 23 rotates, it drives rotating shaft 24 and rotating disk 11 to rotate together, thereby realizing the angle adjustment of rotating disk 11 within the range of 0-360°. Through the set angle adjustment component 2, the electronic component placed on the tooling can be easily adjusted to the required angle, ensuring that various tests can be carried out comprehensively and accurately, thereby meeting the needs of different test angles, avoiding defects that cannot be detected at hidden surfaces or specific angles, and improving the reliability of product quality control.

[0028] like Figure 3-6 As shown, the shape adaptive fixing component 3 includes a base plate 30, with ear seats 31 fixedly connected to both the front and rear sides of the base plate 30. Fixing posts 32 are fixedly connected to the top of both the front and rear ear seats 31. The tops of the front and rear fixing posts 32 are fixedly connected to the bottom of the placement plate 13. A second motor 33 is fixedly connected to the middle of the bottom end of the base plate 30. The output end of the second motor 33 extends through to the top of the base plate 30 and is fixedly connected to a gear 34. Racks 35 are meshed with both the front and rear sides of the gear 34.

[0029] like Figure 3-6As shown, the top of the base plate 30 is fixedly connected to two symmetrical slide rails 36. The outer walls of the two slide rails 36 are slidably connected to two symmetrical movable seats 37. The front side wall of the front rack 35 is fixedly connected to the front inner wall of the left movable seat 37, and the rear side wall of the rear rack 35 is fixedly connected to the rear inner wall of the right movable seat 37. The top of the two movable seats 37 is fixedly connected to four rectangularly distributed movable columns 38. The top of the placement plate 13 has two symmetrical straight slot holes 39 that run in a left-right direction.

[0030] like Figure 3-6 As shown, the tops of the four movable columns 38 extend to the top of the placement plate 13 and are fixedly connected to two symmetrical clamping plates 390. The outer wall of the movable column 38 is slidably connected to the inner wall of the straight slot hole 39. Several hollow columns 391 with equal spacing are fixedly connected to the opposite surfaces of the two clamping plates 390. Springs 392 are fixedly connected to the side of the hollow columns 391 closest to the clamping plates 390. Top columns 393 that are slidably connected to the inner wall of the hollow columns 391 are fixedly connected to the end of the springs 392 away from the clamping plates 390.

[0031] When it is necessary to fix automotive electronic components of different sizes and shapes, the motor 33 is started, and its output shaft drives the gear 34 to rotate. The gear 34 meshes with the racks 35 on the front and rear sides. Due to the transmission relationship between the gear and rack, when the gear 34 rotates, it pushes the rack 35 to move linearly. The front rack 35 is fixed to the left movable seat 37, and the rear rack 35 is fixed to the right movable seat 37. The two movable seats 37 are slidably connected to the two slide rails 36 on the top of the base plate 30, so the linear movement of the rack 35 drives the movable seats 37 to move relative to or away from each other along the slide rails 36. The movable post 38 on the top of the movable seat 37 passes through the straight slot hole 39 on the placement plate 13 and is fixed to the clamping plate 390, thereby driving the clamping plate 390. The clamping plate 390 moves closer to or further away from the electronic component on the placement plate 13 to clamp and fix the electronic component. In addition, the hollow column 391 on the opposite side of the clamping plate 390 contains a spring 392 and a top column 393. When the clamping plate 390 comes into contact with an irregularly shaped electronic component, the spring 392 is compressed and deformed elastically, and the top column 393 slides in the hollow column 391 and fits tightly against the surface of the electronic component. Through the set shape adaptive fixing component 3, it can automatically adjust according to the component outline, realize adaptive and stable fixing of electronic components of different shapes and sizes within a certain range of difference, ensure that all kinds of components can be stably fixed, meet diverse testing needs, and at the same time eliminate the need to design multiple fixing fixtures for different components, reducing testing costs.

[0032] The working principle of this automotive electronics testing fixture will be explained in detail below.

[0033] like Figure 1-6As shown, when it is necessary to fix automotive electronic components of different sizes and shapes, the motor 33 is started, and its output shaft drives the gear 34 to rotate. The gear 34 meshes with the racks 35 on the front and rear sides. Due to the transmission relationship of the gear and rack, when the gear 34 rotates, it pushes the rack 35 to move linearly. The front rack 35 is fixed to the left movable seat 37, and the rear rack 35 is fixed to the right movable seat 37. The two movable seats 37 are slidably connected to the two slide rails 36 on the top of the base plate 30, so the linear movement of the rack 35 drives the movable seats 37 to move relative to or away from each other along the slide rails 36. The movable column 38 on the top of the movable seat 37 passes through the straight slot hole 39 on the placement plate 13 and is fixed to the clamping plate 390, thereby driving the clamping plate. The clamping plate 390 moves closer to or further away from the electronic component on the placement plate 13 to clamp and fix the electronic component. In addition, the hollow column 391 on the opposite side of the clamping plate 390 contains a spring 392 and a top column 393. When the clamping plate 390 comes into contact with an irregularly shaped electronic component, the spring 392 is compressed and deformed elastically, and the top column 393 slides in the hollow column 391 and fits tightly against the surface of the electronic component. Through the set shape adaptive fixing component 3, it can automatically adjust according to the component outline, realize adaptive and stable fixing of electronic components of different shapes and sizes within a certain range of difference, ensure that all kinds of components can be stably fixed, meet diverse testing needs, and at the same time eliminate the need to design multiple fixing fixtures for different components, reducing testing costs.

[0034] When the angle of the clamped automotive electronic component needs to be adjusted, motor 21 is powered on and started. The output shaft rotates, driving worm 22 to rotate. Worm 22 meshes with worm wheel 23. Due to the large transmission ratio and self-locking characteristics of worm gear transmission, the rotation of worm 22 drives worm wheel 23 to rotate. When worm wheel 23 rotates, it drives rotating shaft 24 and rotating disk 11 to rotate together, thereby realizing the angle adjustment of rotating disk 11 within the range of 0-360°. Through the set angle adjustment component 2, the electronic component placed on the tooling can be easily adjusted to the required angle, ensuring that various tests can be carried out comprehensively and accurately, thereby meeting the needs of different test angles, avoiding defects that cannot be detected at hidden surfaces or specific angles, and improving the reliability of product quality control.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
