Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a guiding and positioning device for high-voltage testing of electronic control modules. Background Technology

[0002] With increasing global emphasis on environmental protection and sustainable development, the new energy vehicle industry has rapidly emerged. The power source for new energy vehicles is primarily high-capacity, high-voltage power batteries, typically ranging from 800V to 2000V. As a core component of new energy vehicles, the electronic control module is responsible for managing and controlling the power battery system, ensuring safe vehicle operation and performance optimization.

[0003] The high-voltage testing equipment for the electronic control module adopts a pneumatic pressure transmission structure, which presses down the lower pressure plate so that the spring pins on the lower pressure plate can make good contact with the test points on the PCB, thereby realizing automatic testing of the PCB.

[0004] However, existing high-voltage testing equipment for electronic control modules lacks a guiding and positioning mechanism. When testing test points on the PCB, the spring pins are prone to misalignment with the test points on the PCB, making it impossible for the spring pins to test the test points on the PCB and affecting the efficiency of electronic control module testing. Utility Model Content

[0005] The purpose of this invention is to provide a guiding and positioning device for high-voltage testing of electronic control modules, which aims to solve the problem that existing high-voltage testing equipment for electronic control modules lacks a guiding and positioning mechanism, and is prone to misalignment between the spring pin and the test point on the PCB, making it impossible to test the test point on the PCB.

[0006] To achieve the above objectives, this utility model provides a guiding and positioning device for high-voltage detection of an electronic control module, comprising a detection device body and a guiding assembly. The guiding assembly is assembled within the detection device body and includes a guide rail, a sliding block, a connecting rod, a reinforcing rib, and a buffer frame. The guide rail is fixedly connected to the detection device body and located on both sides of the detection device body. The sliding block is slidably connected to the guide rail and located on one side of the guide rail. The connecting rod is fixedly connected to the sliding block and to a cylinder of the detection device body, and located on one side of the sliding block. The reinforcing rib is fixedly connected to the connecting rod and located outside the connecting rod. The buffer frame is assembled on one side of the sliding block.

[0007] The buffer frame includes a mounting link, a damping rod, and a buffer spring. The mounting link is assembled on both sides of the sliding block. The damping rod is fixedly connected to the mounting link and located at the top of the mounting link. The buffer spring is sleeved on the outside of the damping rod.

[0008] The mounting link includes a connector and a crossbar. The connector is detachably connected to the sliding block and is located on both sides of the sliding block. The crossbar is fixedly connected to the connector and is located on the side of the connector away from the sliding block.

[0009] The high-voltage detection guide and positioning device of the electronic control module also includes a tray positioning component, which is disposed on one side of the detection device body.

[0010] The pallet positioning component includes a pad and a positioning post. The pad is fixedly connected to the main body of the testing equipment and is located inside the main body of the testing equipment. The positioning post is fixedly connected to the pad and is located on top of the pad.

[0011] This utility model discloses a guiding and positioning device for high-voltage testing of an electronic control module. The testing device body uses a pneumatic pressure transmission structure to press down a lower pressure plate, causing the spring pins on the lower pressure plate to contact the test points on the PCB, thus achieving automatic testing of the PCB. When the lower pressure plate is pressed down, it drives the connecting rod to move downward together. The downward movement of the connecting rod causes the sliding block to slide within the guide rail, thereby guiding the lower pressure plate. During the sliding process of the sliding block, the pressure of the lower pressure plate is buffered by the buffer frame to prevent the lower pressure plate from moving down too quickly, which could cause excessive impact and deformation of the spring pins when they contact the PCB. The reinforcing ribs enhance the strength of the connecting rod, preventing deformation or breakage and thus ensuring the sliding block can slide within the guide rail. This invention adds a guiding component to the traditional testing equipment, guiding the lower pressure plate downwards and preventing misalignment between the spring pin and the test point on the PCB. This solves the problem of existing high-voltage testing equipment for electronic control modules lacking a guiding and positioning mechanism, which easily leads to misalignment between the spring pin and the test point on the PCB, making it impossible to test the test point on the PCB.

Detailed Implementation

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] Please see Figures 1 to 2 This utility model provides a guiding and positioning device for high-voltage detection of electronic control modules, including a detection device body 1 and a guiding component 2. The guiding component 2 is assembled inside the detection device body 1. The guiding component 2 includes a guide slide rail 3, a sliding block 4, a connecting rod 5, a reinforcing rib 6, and a buffer frame 7. The guide slide rail 3 is fixedly connected to the detection device body 1 and is located on both sides of the detection device body 1. The sliding block 4 is slidably connected to the guide slide rail 3 and is located on one side of the guide slide rail 3. The connecting rod 5 is fixedly connected to the sliding block 4 and is also fixedly connected to the cylinder of the detection device body 1 and is located on one side of the sliding block 4. The reinforcing rib 6 is fixedly connected to the connecting rod 5 and is located outside the connecting rod 5. The buffer frame 7 is assembled on one side of the sliding block 4.

[0018] In this embodiment, the testing device body 1 presses down the lower pressure plate via a pneumatic pressure transmission structure, causing the spring pins on the lower pressure plate to contact the test points on the PCB, thus achieving automatic testing of the PCB. When the lower pressure plate is pressed down, it drives the connecting rod 5 to move downwards together. The downward movement of the connecting rod 5 causes the sliding block 4 to slide within the guide rail 3, thereby guiding the lower pressure plate. During the sliding process of the sliding block 4, the pressure of the lower pressure plate is buffered by the buffer frame 7, preventing the lower pressure plate from moving down too quickly, which could cause excessive impact and deformation of the spring pins when they contact the PCB, thus improving the performance of the testing device body. The reinforcing rib 6 enhances the strength of the connecting rod 5, preventing deformation or breakage and thus preventing the sliding block 4 from sliding within the guide rail 3. This invention adds a guide component 2 to the traditional testing equipment, guiding the lower pressure plate downwards and preventing the spring pin from shifting off from the test point on the PCB. This solves the problem of existing high-voltage testing equipment for electronic control modules lacking a guiding and positioning mechanism, which easily leads to the spring pin shifting off from the test point on the PCB, making it impossible to test the test point on the PCB.

[0019] Furthermore, the buffer frame 7 includes a mounting link 8, a damping rod 9, and a buffer spring 10. The mounting link 8 is assembled on both sides of the sliding block 4. The damping rod 9 is fixedly connected to the mounting link 8 and is located at the top of the mounting link 8. The buffer spring 10 is sleeved on the outside of the damping rod 9.

[0020] In this embodiment, the mounting rod 8 is used to connect the damping rod 9 to the sliding block 4. When the sliding block 4 slides down, the mounting rod 8 stretches the damping rod 9, thereby stretching the buffer spring 10 and the buffer medium inside the damping rod 9, thus achieving buffering of the lower pressure plate. This avoids the lower pressure plate moving down too quickly, which would cause excessive impact and deformation when the spring pin on it contacts the PCB, thereby improving the service life of the testing equipment body 1.

[0021] Furthermore, the mounting link 8 includes a connector 11 and a crossbar 12. The connector 11 is detachably connected to the sliding block 4 and is located on both sides of the sliding block 4. The crossbar 12 is fixedly connected to the connector 11 and is located on the side of the connector 11 away from the sliding block 4.

[0022] In this embodiment, the connector 11 facilitates the connection between the crossbar 12 and the damping rod 9, and the crossbar 12 provides installation conditions for the damping rod 9.

[0023] Furthermore, the high-voltage detection guide and positioning device of the electronic control module also includes a tray positioning component 13, which is disposed on one side of the detection device body 1.

[0024] In this embodiment, the tray positioning component 13 positions the electronic control module fed into the testing equipment body 1, so that the spring pin on the lower pressure plate can accurately contact the test point on the PCB.

[0025] Furthermore, the pallet positioning component 13 includes a pad 14 and a positioning post 15. The pad 14 is fixedly connected to the detection equipment body 1 and is located inside the detection equipment body 1. The positioning post 15 is fixedly connected to the pad 14 and is located on top of the pad 14.

[0026] In this embodiment, the pad 14 is fixed inside the testing equipment body 1 by bolts, and the positioning column 15 is used to position the electronic control module sent into the testing equipment body 1, so that the spring pin on the lower pressure plate can accurately contact the test point on the PCB.

[0027] The above-disclosed embodiments are merely preferred embodiments of a high-voltage detection guide and positioning device for an electronic control module according to this application, and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
