Testing equipment for automotive motor controllers Technical Field
[0001] This utility model relates to a testing device, specifically a testing device for an automotive motor controller. Background Technology
[0002] With the rapid development of the new energy vehicle industry, the accuracy and efficiency of performance testing of motor controllers, as one of the core components, directly affect the safety and reliability of the entire vehicle. Currently, domestic manufacturers typically need to design dedicated controller testing fixtures based on the test types (such as voltage, current, temperature, and signals) of the product under test during motor controller testing. Traditional fixtures lack versatility and adjustability, making them difficult to reuse or quickly adapt to new testing requirements. This leads to problems such as redundant production equipment, complex warehouse management, and extended R&D cycles. Therefore, every time a new controller is developed or testing requirements change, companies need to invest significant resources in designing, processing, and maintaining dedicated fixtures, resulting in a significant increase in testing costs. Summary of the Invention
[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a test device for automotive motor controllers that can select the corresponding test device according to different test types, improve the versatility of test requirements, and reduce tooling manufacturing and maintenance costs.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A testing device for an automotive motor controller includes a test upper bracket and a lifting drive device located below it. The lifting drive device includes a lifting platform and a lifting device located below the lifting platform. The top surface of the lifting platform is used to place the controller to be tested. The top support of the lifting device is fixed to the bottom of the lifting platform and can drive the lifting platform to move up and down. An upper limit device is fixedly connected to the test upper bracket and can limit the contact of the controller to be tested placed on the lifting platform. The lifting device can drive the lifting platform to rise so that the controller to be tested on the lifting platform abuts against the upper limit device. A controller clamping device is fixedly connected to the test upper bracket and can clamp and fix the controller to be tested abutting against the upper limit device. A plurality of test devices are also fixedly connected to the test upper bracket and can perform different functional tests on the controller to be tested. The test devices have test wiring harness interfaces.
[0006] In this invention, the controller under test is placed on the top surface of the lifting platform. Then, the lifting device is activated to move the controller upwards, causing it to abut against the upper limit device. The upper limit device and the lifting platform clamp the controller. Next, the controller clamping device is activated to clamp and secure the controller. Then, according to the required test content and requirements, the corresponding test equipment is selected, and the test equipment is connected to the controller under test via test wiring harnesses. This allows for the selection of appropriate test equipment for different controller models and different test types, improving the versatility of product testing and reducing equipment manufacturing and maintenance costs.
[0007] As an optimization, the top surface of the lifting platform is equipped with a support and positioning device for supporting and positioning the controller under test. The support and positioning device includes multiple support bases fixedly connected to the lifting platform. Each support base has a vertically protruding support column on its top surface that can abut against and support the controller at its bottom support position. Since the controllers are irregularly shaped, they cannot be placed stably on the lifting platform. Therefore, the support and positioning device on the top surface of the lifting platform, with support columns of corresponding lengths for different support positions of the controller, provides better and more stable support and facilitates clamping the controller later.
[0008] As an optimization, the lifting platform includes a lifting base plate and a support plate located above the lifting base plate. The support positioning device is installed on the support plate. Multiple support bosses for supporting the support plate are fixedly connected to the top surface of the lifting base plate. At least two support bosses have vertically protruding positioning posts at their top ends. Positioning holes are provided on the support plate corresponding to the positions of the positioning posts, allowing the positioning posts to be inserted into the corresponding positioning holes and limiting the horizontal movement of the support plate. Support plate limiting seats are fixedly connected to both sides of the support plate on the lifting base plate in the horizontal direction. Support plate limiting holes are recessed on the sides of the support plate corresponding to the positions of the support plate limiting seats in the horizontal direction. Rotary plungers are fixedly connected to the support plate limiting seats, and the pins on the rotary plungers can be inserted into the support plate limiting holes to limit the vertical movement of the support plate. Different controllers require different support positions; therefore, by changing the support plate, support positioning devices for different controllers can be installed on different support plates, facilitating replacement operations.
[0009] As an optimization, the controller clamping device includes two horizontally opposite clamping bases. A guide rail extending along the opposite direction of the two clamping bases is fixedly connected to the clamping bases. A clamping slide block that can slide along the extension direction is slidably connected to the guide rail. The space between the two clamping slide blocks is a clamping space for clamping the controller under test. The opposite ends of the two clamping slide blocks are respectively fixedly connected to clamping protrusions that can be inserted into the sockets on the controller under test. The number of clamping protrusions is at least three. A clamping telescopic driver is fixedly connected to the clamping base. One end of the clamping telescopic driver extends out to a telescopic clamping rod that can extend and retract along the extension direction parallel to the guide rail. The telescopic clamping rod is fixedly connected to the clamping slide block on its corresponding side. The clamping telescopic driver can drive the clamping slide block to clamp and fix the controller under test through the telescopic clamping rod. By controlling the retraction of the telescopic clamping rod, the controller can easily enter the clamping space and abut against the upper limit device. Then, the telescopic clamping rod is extended, and the clamping protrusion on the clamping slide is inserted into the corresponding hole on the controller. Through three-point positioning, stable clamping of the controller is achieved.
[0010] As an optimization, a telescopic limiting device is provided between the clamping base and the clamping slide. The telescopic limiting device includes a fixed limiting seat and a movable limiting seat spaced apart along the extension direction of the guide slide rail. The fixed limiting seat is fixedly connected to the clamping base, and the movable limiting seat is located on the side of the fixed limiting seat facing away from the direction of the clamping space and is fixedly connected to the clamping slide. A travel limiting screw I and a travel limiting screw II are respectively provided on the fixed limiting seat, capable of slidingly engaging with the fixed limiting seat along a direction parallel to the extension direction of the guide slide rail. The end of the travel limiting screw I facing the movable limiting seat protrudes to form a connecting rod and is fixedly connected to the movable limiting seat through the connecting rod. A travel limit nut I is threadedly fitted on the rod body of the fixed limit seat at a position opposite to the movable limit seat. When the travel limit nut I abuts against the fixed limit seat, it can limit the movement of the clamping slide away from the clamping space. A travel limit nut II is threadedly fitted on the rod body of the travel limit screw II at a position opposite to the movable limit seat. The travel limit nut II abuts against the fixed limit seat. When the movable limit seat moves toward the fixed limit seat, the movable limit seat can abut against the end of the travel limit screw II toward the movable limit seat to limit the movement of the clamping slide toward the clamping space. The movement of the clamping slide causes the movement of the movable limit seat. When moving away from the clamping space, this movement drives the travel limit screw I, which then abuts against the fixed limit seat via the travel limit nut I, limiting the minimum travel distance of the entire clamping stroke. Conversely, when moving towards the clamping space, the movable limit seat abuts against the end of the travel limit screw II, which in turn abuts against the fixed limit seat via the travel limit nut II, limiting the maximum travel distance of the entire clamping stroke. Adjusting the positions of the travel limit nuts I and II, and thus the entire stroke, allows for adjustment.
[0011] As an optimization, the upper limit device includes at least two blocks that can abut against different positions on the top of the controller under test. The tops of the blocks are fixedly connected to the test support via a fixed bracket. The irregular shape of the controller cannot be limited by the clamping surface; instead, the restriction at different points allows for better abutment and limitation of the controller after it has been lifted up.
[0012] As an optimization, the stop includes an upper base and a lower protrusion located at the bottom of the upper base. The upper base and the lower protrusion are fixedly connected by bolts. The bottom protrusion of the lower protrusion forms at least two limiting protrusions that can respectively abut against different positions on the top of the controller under test. For different controllers, by replacing the lower protrusion with different specifications, better abutment and limiting of the controller can be achieved.
[0013] Compared with existing technologies, this utility model can meet the testing needs of different test points and different test types, thereby reducing the manufacturing cost of the entire testing device; by lifting and clamping the controller, more product testing positions are provided, and the test selectivity is better.
