Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing tooling technology, and more specifically to a test bench for testing the torque of a car door mounted on a car window motor. Background Technology
[0002] In the 21st century, the automotive industry has developed rapidly. Cars have evolved from old-fashioned, manually controlled window operation to the use of various window motors for operation. Based on the current technological maturity, virtually all vehicles currently in production use window motors.
[0003] The selection and analysis of automotive window regulator motors are based on individual components, without clarifying the root cause. Furthermore, the existing car doors are too large, making it difficult to disassemble and assemble the window regulator, which in turn makes testing on the car door challenging.
[0004] Meanwhile, current testing methods for motor torque use torque sensors to test individual motors. However, this testing structure is too bulky to be connected to the car door for testing. It can only measure the motor's test torque and cannot confirm the torque output after the motor is installed, resulting in cumbersome and difficult testing, which needs to be improved. Summary of the Invention
[0005] In view of this, the purpose of this application is to provide a test bench for the actual torque of automotive window regulator motors on various types of car doors. The specific solution is as follows:
[0006] A test bench for testing the torque of a car door using a car window motor includes an upper plate, a lower plate, and a central fixture fixed between the upper and lower plates. Multiple upper connecting columns are provided on the side of the upper plate away from the lower plate, and these upper connecting columns are used to connect and fix to the test motor. One end of the central fixture is provided with a transmission connector for connecting to the test motor, and the other end is provided with a connector for connecting to the door panel and transmitting torque. A torque sensor is also provided in the central fixture.
[0007] Preferably, the upper connecting post is threadedly connected to the upper plate, and the upper plate is provided with a plurality of upper threaded holes for matching the upper connecting post.
[0008] Preferably, the multiple upper connecting columns are formed in at least two groups, and each group is used to connect and fix with the corresponding model test motor.
[0009] Preferably, the lower plate is provided with multiple lower connecting posts, which are used to connect and fix to the door panel.
[0010] Preferably, the multiple lower connecting columns are formed in at least two groups, and each group is used to connect and fix to the corresponding style door panel.
[0011] Preferably, the lower connecting post is threadedly connected to the lower plate, and the lower plate is provided with a plurality of threaded holes for matching the lower connecting post.
[0012] As can be seen from the above solutions, this application provides a vehicle door torque testing bench for automotive window motors. This vehicle door torque testing bench for automotive window motors has the following beneficial effects: the detachable structure of the vehicle door torque testing bench for automotive window motors enables positioning and matching with the threaded holes of various types of door panels, and it has the ability to cooperate with the corresponding test motors. Thus, based on the central fixture, the motor is connected to the door panel lifter connector, and the torque sensor detects the real-time output torque of the motor. Attached Figure Description

[0014] Explanation of reference numerals in the attached drawings: 1. Upper plate; 11. Upper connecting post; 2. Central fixture; 21. Transmission connector; 3. Torque sensor; 4. Lower plate; 41. Lower connecting post; 5. Connector; 6. Test motor. Detailed Implementation
[0015] To make the technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0016] like Figure 1 As shown, a vehicle door torque testing bench for an automotive window motor includes an upper plate 1, a lower plate 4, and a central fixture 2 fixed between the upper plate 1 and the lower plate 4. It should be noted that multiple upper connecting posts 11 are provided on the side of the upper plate 1 away from the lower plate 4, and these upper connecting posts 11 are used to connect and fix to the test motor 6. One end of the central fixture 2 is provided with a transmission connector 21 for connecting to the test motor 6, and the other end is provided with a connector 5 for connecting to the door panel and transmitting torque. A torque sensor 3 is also provided on the central fixture 2.
[0017] The torque sensor 3 collects and tests the real-time output torque of the motor 6, and records the output torque value.
[0018] It should be mentioned that in this embodiment, the upper connecting post 11 is threadedly connected to the upper plate 1, and the upper plate 1 is provided with multiple threaded holes for matching the upper connecting post 11. Furthermore, the multiple upper connecting posts 11 form at least two sets, each set being used to connect and fix to the corresponding model test motor 6. Correspondingly, the lower plate 4 is provided with multiple lower connecting posts 41, which are used to connect and fix to the door panel. The multiple lower connecting posts 41 form at least two sets, each set being used to connect and fix to the corresponding model door panel. The lower connecting posts 41 are threadedly connected to the lower plate 4, and the lower plate 4 is provided with multiple threaded holes for matching the lower connecting posts 41.
[0019] In use, the upper connecting column 11 is first connected and fixed to the test motor 6, and the lower connecting column 41 is connected and fixed to the car door panel. After the test motor 6 is started, the test motor 6 drives the central fixture 2 to run. At this time, the torque sensor 3 is started and monitors the output torque value in real time. At the same time, the lifting status of the car window is observed based on the door panel, so that when the lifting of the car window is abnormal, the output torque can be used to determine whether the test motor 6 is in a faulty state.
[0020] In summary, this application provides a vehicle door torque testing bench for automotive window motors. This test bench achieves positioning and matching with the threaded holes of various door panels through its detachable structure, and has a test motor 6 that matches the corresponding model. Thus, based on the central fixture 2, the motor is connected to the door panel lifter connector, and the torque sensor 3 detects the real-time output torque of the motor.
