Description

Technical Field

[0001] This invention relates to the field of vehicle body controller testing equipment, and more specifically to a vehicle body controller testing fixture. Background Technology

[0002] The body control unit, also known as the body computer, is an electronic control unit (ECU) used in automotive engineering to control the vehicle's electrical systems and is a crucial component of a car. During the production process, the body control unit requires electrical testing using a testing system and testing fixtures.

[0003] Existing body controller testing fixtures mainly include test probes that are electrically connected to the test system and a carrier plate for placing the body controller. During testing, the test probes are plugged into the test points on the body controller.

[0004] In order to reduce damage during body controller testing, existing technologies typically use elastic probes for testing. However, due to the elasticity of the probes, there is a problem of unstable contact after they are inserted. Summary of the Invention

The first insertion component and the second insertion component are electrically connected. The first side insertion bracket is slidably disposed on the second side insertion bracket. The second side insertion bracket is provided with a feeding cylinder and an elastic probe electrically connected to the testing system. The elastic probe is in contact with the first insertion component. The output end of the feeding cylinder is provided with a first actuating block. The second actuating block is rotatably connected to the second side insertion bracket. The feeding cylinder is used to drive the first actuating block to move and push the second actuating block to rotate, so that the second actuating block pushes the first insertion component and the elastic probe on the first side insertion bracket to press against each other.

[0008] A lifting assembly for lifting a carrier plate and allowing the body controller and connector to be inserted.

[0009] Furthermore, the second side insert is provided with a guide post, and the first side insert is provided with a guide hole, with the guide post passing through the guide hole.

[0011] Furthermore, the carrier plate is also provided with a limiting mechanism, which includes a limiting rod one, a limiting rod two, and a limiting spring. The limiting rod one is provided with an inclined sliding groove, and the limiting rod two is provided with a sliding rod. The sliding rod is slidably disposed in the sliding groove. The limiting rod one is elastically connected to the carrier plate through the limiting spring, and the limiting rod two is pressed against the body controller through the limiting spring. When the body controller is placed, the limiting rod one slides away from the body controller through the sliding groove.

[0012] Furthermore, the first limiting rod is provided with a first limiting groove, and the second limiting rod is slidably disposed within the first limiting groove.

[0013] Furthermore, the second limiting rod is provided with a second limiting groove, which corresponds to the first limiting rod.

[0015] Furthermore, the side insert bracket is provided with a positioning post, and the carrier plate is provided with a positioning hole, with the positioning post and the positioning hole corresponding to each other.

[0016] Furthermore, the side insert bracket is also provided with a positioning post two, and a compression spring is sleeved on the positioning post two. The positioning post two is elastically connected to the side insert bracket two through the compression spring. The carrier plate is provided with a positioning hole two corresponding to the positioning post two. When the upper needle plate and the body controller are inserted, the positioning post two is located in the positioning hole two.

[0017] Furthermore, the turntable is also equipped with corresponding positioning cylinders and barcode scanners. The output end of the positioning cylinder is equipped with a positioning block.

Detailed Implementation

[0031] To make the technical problem to be solved, the technical solution, and the beneficial effects of this invention clearer, the invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the invention, and therefore only shows the components relevant to the invention. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0032] Please refer to Figure 1 This invention provides a vehicle body controller testing fixture, including a turntable 10 and a lifting assembly disposed at the bottom of the turntable 10. The turntable 10 is connected to a drive motor (not shown in the figure), which drives the turntable 10 to rotate. The turntable 10 is provided with a plug-in assembly 20 and a carrier plate 12 for placing a vehicle body controller 200. The carrier plate 12 is provided with a placement slot 121 for placing the vehicle body controller 200. Specifically, in this embodiment, the specific structure of the vehicle body controller 200 is not shown.

[0033] Please refer to Figure 9 and Figure 10 The carrier plate 12 is also provided with a limiting mechanism, which includes a limiting rod 13, a limiting rod 14 and a limiting spring 15. The limiting rod 13 is provided with an inclined sliding groove 131, and the limiting rod 14 is provided with a sliding rod 141. The sliding rod 141 is slidably disposed in the sliding groove 131. The limiting rod 13 is elastically connected to the carrier plate 12 through the limiting spring 15, and the limiting rod 14 is pressed against the body controller 200 through the limiting spring 15. When the body controller 200 is placed, the limiting rod 13 slides away from the body controller 200 through the sliding groove 131.

[0034] Specifically, in this embodiment, the first limiting rod 13 and the second limiting rod 14 slide along the width and length directions of the carrier plate 12, respectively.

[0035] By cooperating with the first limiting rod 13, the second limiting rod 14, the limiting spring 15, and the inclined sliding groove 131, when the body controller 200 is placed in the placement groove 121, the second limiting rod 14 is always pressed against the body controller 200 by the elastic force of the limiting spring 15, thereby limiting the body controller 200 and making it less likely to detach from the carrier plate 12 due to the inertia generated by the rotation when the body controller 200 rotates with the turntable 10.

[0036] To further limit the relative positioning of limit rod 13 and limit rod 14, please refer to... Figure 10 The first limiting rod 13 is provided with a first limiting groove 132, and the second limiting rod 14 is slidably disposed within the first limiting groove 132. The second limiting rod 14 is provided with a second limiting groove 142, which corresponds to the first limiting rod 13.

[0037] Please refer to Figure 3 , Figure 4 and Figure 5 The plug-in assembly 20 includes a first side plug holder 21 and a second side plug holder 22. The first side plug holder 21 is provided with a first plug-in component 23 and an upper needle plate 24. The upper needle plate 24 is provided with a second plug-in component 241. The first plug-in component 23 and the second plug-in component 241 are electrically connected. The first side plug holder 21 is slidably disposed on the second side plug holder 22. Specifically, the first side plug holder is provided with a sliding protrusion 215, and the second side plug holder 22 is provided with a side sliding groove 223. The sliding protrusion 215 is slidably disposed within the side sliding groove 223.

[0038] Please refer to Figure 5 The second side insert 22 is equipped with a material-feeding cylinder 25 and an elastic probe 26 electrically connected to the test system. The elastic probe 26 is in contact with the first insert 23. The output end of the material-feeding cylinder 25 is equipped with a first actuating block 251. The second actuating block 221 is rotatably connected to the second side insert 22. The material-feeding cylinder 25 is used to drive the first actuating block 251 to move and push the second actuating block 221 to rotate, so that the second actuating block 221 pushes the first insert 23 and the elastic probe 26 on the first side insert 21 to press against each other.

[0039] Specifically, in this embodiment, two sets of plug-in assemblies 20 are sequentially arranged along the periphery of the turntable 10, respectively used to test different performance characteristics of the body controller 200. Plug-in 1 23 and plug-in 241 are both adapter plates in the prior art, and plug-in 1 23 and plug-in 241 are electrically connected by a wire (not shown in the figure). When plug-in 241 on the upper needle plate 24 is plugged into the body controller 200, the movement direction of the body controller 200 is along the thickness direction of the turntable 10. When plug-in 1 23 and the elastic probe 26 are pressed together, the movement direction of plug-in 1 23 is along the diameter direction of the turntable 10. The side insert bracket 21 is provided with a plug groove 213 corresponding to the actuating block 221. The actuating block 221 pushes the side insert bracket 21 to slide by pushing the inner wall of the plug groove 213.

[0040] By setting up the material feeding cylinder 25, the first actuating block 251 and the second actuating block 221, after the body controller 200 and the first connector 23 are connected, the material feeding cylinder 25 drives the first actuating block 251 to press the elastic probe 26 and the second connector 241 relatively together, thereby reducing the problem of unstable contact after the elastic probe 26 is connected due to its elasticity.

[0041] Please refer to Figure 5 The second side insert 22 is provided with a guide post 222, and the first side insert 21 is provided with a guide hole 214, with the guide post 222 passing through the guide hole 214. The guide post 222 and the guide hole 214 cooperate to facilitate the relative positioning of the first side insert 21 and the second side insert 22, thereby facilitating the clamping and guiding of the first connector 23 on the first side insert 21 and the elastic probe 26 on the second side insert 22.

[0042] Please refer to Figure 7 and Figure 8 The lifting assembly includes a lifting cylinder 31 mounted on a turntable 10. The output end of the lifting cylinder 31 is equipped with a lifting frame 32. The lifting frame 32 has a positioning post 321. The carrier plate 12 has a positioning hole 322 that matches the positioning post 321. When the lifting cylinder 31 drives the lifting frame 32 to lift the carrier plate 12, the positioning post 321 is positioned within the positioning hole 322. The cooperation between the positioning hole 322 and the positioning post 321 facilitates the positioning of the lifting frame 32 relative to the carrier plate 12, improving the stability of the lifting process.

[0043] Please refer to Figure 4 , Figure 6 and Figure 9The side insert bracket 21 is equipped with a positioning post 211, and the carrier plate 12 is equipped with a positioning hole 123, with the positioning post 211 and the positioning hole 123 corresponding to each other. The positioning post 211 and the positioning hole 123 work together to facilitate relative positioning of the side insert bracket 21 and the carrier plate 12 when the upper needle plate 24 and the body controller 200 are inserted, thereby reducing the possibility of deviation during insertion and improving the accuracy of the insertion.

[0044] Please refer to Figure 4 , Figure 6 and Figure 9 The side insert bracket 21 is also provided with a positioning post 212. A compression spring 2121 is sleeved on the positioning post 212. The positioning post 212 is elastically connected to the side insert bracket 22 through the compression spring 2121. The carrier plate 12 is provided with a positioning hole 2124 corresponding to the positioning post 212. When the upper needle plate 24 and the body controller 200 are inserted, the positioning post 212 is located in the positioning hole 2124.

[0045] By cooperating with positioning pin 212 and positioning hole 124, the side bracket 21 and carrier plate 12 are positioned relative to each other when the upper needle plate 24 and the body controller 200 are inserted, thereby reducing the possibility of deviation when the upper needle plate 24 and the body controller 200 are inserted and improving the accuracy of insertion. At the same time, the compression spring 2121 reduces the pressure exerted by the upper needle plate 24 on the body controller 200 during insertion, thereby reducing the damage to the body controller 200 during insertion.

[0046] Specifically, in this embodiment, positioning hole 123 and positioning hole 124 are both located on the upper end face of the carrier plate 12, and positioning hole 322 is located on the lower end face of the carrier plate 12. Positioning hole 123 and positioning post 211 are compatible with each other, and positioning hole 124 and positioning post 321 are compatible with each other. The diameter of positioning hole 322 is slightly larger than that of positioning post 321, so that when the material feeding cylinder 25 drives the actuating block 251 to push the plug-in part 23 and the elastic probe 26 on the side insert bracket 21 to press together, the carrier plate 12 can drive the body controller 200 to generate a slight displacement relative to the lifting frame 32, so that it moves together with the side insert bracket 21, ensuring the stability of the plug-in part 23 and the body controller 200.

[0047] Please refer to Figure 1 and Figure 2The turntable 10 is also equipped with corresponding positioning cylinders 16 and barcode scanners 17. The output end of the positioning cylinder 16 is equipped with a positioning block 161. The positioning cylinder 16 is used to drive the positioning block 161 to press against the carrier plate 12. The barcode scanner 17 is used to identify the barcode information on the body controller 200. After the body controller 200 is placed on the carrier plate 12, the information is first identified by the barcode scanner 17, and then the turntable 10 is rotated to the insertion assembly 20 for insertion.
