Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, specifically a portable vibration testing device for automobile controllers. Background Technology

[0002] The vehicle controller is a core electronic control unit in a vehicle system, commonly known as the vehicle computer. It mainly controls the corresponding actuators to achieve the driver's driving intentions through the driver's operation of the vehicle, such as the gear shift, accelerator pedal and brake pedal.

[0003] Before being tested on a vehicle, the automotive controller needs to be tested individually. Generally, this testing is outsourced to testing agencies. However, because these agencies charge high fees, controller manufacturers often shorten the testing cycle to reduce costs. But products with shortened testing cycles are less likely to have design flaws. Therefore, a convenient vibration testing device for automotive controllers is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a convenient vibration testing device for automotive controllers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a portable automobile controller vibration testing device, comprising a test bench, the top of which is divided into a test area and a speed adjustment area, a first groove is provided in the test area, a vibration table is slidably connected in the first groove, and a swing mechanism that drives the vibration table to move laterally is installed in the test bench;

[0006] The vibration table includes a base plate and a fixing plate. A second groove is formed on the base plate. Two first sliding grooves are symmetrically formed on both sides of the second groove in the base plate. The two sides of the fixing plate pass through the two first sliding grooves respectively. Two springs are symmetrically fixedly connected in the first sliding grooves on both sides of the fixing plate.

[0007] As a further preferred embodiment of this technical solution: the swing mechanism drives the vibration table to reciprocate within the first groove on the test bench, thereby causing the fixed plate 5 on the vibration table to swing back and forth within the second groove 7 on the base plate 4. Whenever the fixed plate swings to the limit position of the second groove, it is ejected by the spring 6. This multi-stage swinging method increases the vibration frequency of the controller on the fixed plate, thereby achieving the test efficiency per unit time.

[0008] As a further preferred embodiment of this technical solution: the swing mechanism includes a motor, a crank arm is mounted on the output end of the motor, a support plate for stabilizing the motor is mounted below the crank arm, a connecting rod is mounted on the end of the crank arm away from the motor, a push block is mounted on the end of the connecting rod away from the crank arm, and the push block is mounted on the bottom of the base plate. The rotation of the motor sequentially drives the crank arm, the connecting rod and the push block, thereby realizing that the crank arm drives the connecting rod mounted thereon, and the connecting rod drives the push block mounted at one end of it to perform push-pull motion.

[0009] As a further preferred embodiment of this technical solution: a second sliding groove is provided on the test area and located in the first groove, and the second sliding groove is connected to the interior of the test bench. The above arrangement ensures the stability of the vibration table driven by the swing mechanism.

[0010] As a further preferred embodiment of this technical solution: two wire harness slots are symmetrically provided on both sides of the first groove in the test area, and the wire harness slots are connected to the interior of the test bench. The wire harness slots can be used to perform load tests on the controller and to test the firmness of the terminals and wire harness connectors.

[0011] As a further preferred embodiment of this technical solution: the fixing plate has multiple fixing holes, through which pairs of controllers can be installed, thereby facilitating the comparison of test results.

[0012] As a further preferred embodiment of this technical solution: two inclined grooves are symmetrically provided on both sides of the substrate, which reduce the wear of the wire harness on the vibration table during the movement of the vibration table.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a swing mechanism to drive the vibration table to reciprocate in the first groove of the test bench, thereby causing the fixed plate on the vibration table to swing back and forth in the second groove on the base plate. Whenever the fixed plate swings to the limit position of the second groove, it will be ejected by the spring. This multi-stage swing method increases the vibration frequency of the controller on the fixed plate, realizes the testing efficiency per unit time, and allows the device to continue testing after the testing mechanism has completed the test, thereby improving the product testing cycle and identifying potential product quality problems.

[0015] 2. In this utility model, the controller can be tested under load through the wire harness groove. During the vibration process, when poor signal contact occurs, it can be detected whether the controller's processing mechanism meets the specified design. At the same time, the firmness of the terminals and wire harness connectors can also be tested. Furthermore, the multiple fixing holes can be used to install pairs of controllers, which facilitates the comparison of test results and effectively improves the accuracy of test data.
