Description

Technical Field

[0001] This utility model relates to the field of automotive component performance testing technology, and in particular to a durability testing device for automotive combination switches. Background Technology

[0002] A car combination switch is a switch located below the steering wheel used to control functions such as turn signals, high and low beam headlights, and windshield wipers. It is a combination of multiple switches, and its operation involves moving a lever up and down. It is one of the most important components of a vehicle.

[0003] Because automotive combination control switches are related to vehicle operation and driver safety, durability testing is necessary, and the accuracy of the test results is also very important.

[0004] The existing devices still have the following drawbacks in use:

[0005] Automotive combination switches typically have two levers symmetrically arranged on both sides. However, existing devices cannot test both levers, which affects the testing efficiency of automotive combination switches and hinders their widespread use. Utility Model Content

[0006] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. To overcome the aforementioned deficiencies of existing technologies, this utility model provides a durability testing device for automotive combination switches, aiming to solve the problems mentioned in the background.

[0007] To achieve the above objectives, this utility model provides a durability testing device for automotive combination switches, comprising: a base, a test platform disposed on the upper surface of the base, a limiting component disposed on the upper surface of the test platform for fixing and limiting the automotive combination switch, a test component disposed above the base for testing the automotive combination switch, the test component being mounted above the base by a fixing component, and two sets of test components and fixing components being symmetrically arranged about the longitudinal midline of the test platform.

[0008] The base design provides overall stability and support for the device. The upper surface of the test platform is secured to the automotive combination switch under test via limiting components. After the automotive combination switch is secured, it undergoes durability testing via the test components. The fixing components are used to mount the test components on top of the base. The symmetrical design of the fixing components and test components on the left and right sides of the test platform forms two test stations. This allows for simultaneous testing of both sides of the automotive combination switch's levers, improving testing efficiency. Furthermore, different number of tests and pressure settings can be set during the test to compare and contrast the levers on both sides of the automotive combination switch, enhancing test accuracy.

[0009] Preferably, the limiting component includes a limiting rod and a limiting platform;

[0010] The limit rod is vertically set in the middle of the upper surface of the test platform;

[0011] The limiting platform is set on the upper surface of the test platform, located on the left and right sides of the limiting rod, and the installation height of the limiting platform is lower than the installation height of the limiting rod.

[0012] The limiting rod connects to the through hole on the assembly of the automotive combination switch, thereby fixing the entire automotive combination switch onto the limiting platform. The limiting platform has pre-set bolt holes corresponding to those on the automotive combination switch, and bolts are inserted into these holes to ensure the stability of the connection between the automotive combination switch and the limiting platform. The pre-set height difference between the limiting platform and the limiting rod facilitates the operator's handling of the automotive combination switch, demonstrating the practicality of this device.

[0013] Preferably, the limiting rod and the test platform form a detachable structure through a connecting component, which includes a connecting block and a connecting groove;

[0014] The connecting block is located at the bottom of the limiting rod, and the outer surface of the connecting block is pre-threaded;

[0015] The connecting groove is pre-set on the upper surface of the test platform, and the inner wall of the connecting groove is pre-threaded.

[0016] The limit rod forms a threaded, detachable structure through a connecting block and a connecting groove. The threaded structure is designed with a self-locking function, which ensures the stability of the connection between the limit rod and the test platform. At the same time, it does not affect the experimenter's ability to select a limit rod with a corresponding radius according to actual needs, so as to be suitable for different models of automotive combination switches, avoiding limitations for the experimenter during use.

[0017] Preferably, the test assembly includes an electric actuator and a pressure block;

[0018] The electric actuators are vertically positioned on the top and bottom sides of the automotive combination switch;

[0019] The pressure block is installed at the output end of the electric actuator.

[0020] The electric actuator uses a commercially available structure to drive the pressure block to move vertically up and down. A pressure sensor is pre-installed on the pressure block. When the pressure block touches the lever, pressure is generated and applied to the pressure detector. The data from the pressure sensor is transmitted to the display screen on the control box for easy reading by the experimenter. Both the pressure block and the pressure sensor use commercially available structures, such as HSP-HW416MC. Their specific structure, working principle, and circuit diagram are common knowledge to those skilled in the art and will not be described further. When using the test assembly, the electric actuator can be horizontally set at a specified height on the upright to detect the forward and backward movement of the automotive combination switch lever. This method is an equivalent replacement for the method described above, and the working principle is the same as described above, so it will not be described further.

[0021] Preferably, the fixing component includes a column, a support rod, and a positioning sleeve;

[0022] The columns are fixedly installed on the upper surface of the base, located on the left and right sides of the test platform;

[0023] The support rod is installed horizontally on the column, located on the side closest to the test platform, and there are two support rods arranged symmetrically in parallel on the column;

[0024] The positioning sleeve is mounted on the support rod, and the lower end face of the positioning sleeve is connected to the fixed end of the electric actuator.

[0025] The column, support rod, and base are welded together, ensuring a stable connection. The support rod connects to the positioning sleeve. The positioning sleeve connects to the electric actuator.

[0026] Preferably, the positioning sleeve and the support rod are slidably connected, and a fastening bolt is pre-set on the top of the positioning sleeve.

[0027] The positioning sleeve is fitted onto the outer surface of the support rod and can slide left and right on the outer surface of the support rod. This design allows the experimenter to easily adjust the installation position of the pressure block according to actual needs, further demonstrating the practicality of this device. Fastening bolts are used to fix the positioning sleeve and the support rod, thus ensuring the stability of their connection.

[0028] Preferably, it also includes an electrical control box, which is located on one side of the base and is electrically connected to the test component.

[0029] The electrical control box controls the number of times and the power of the electric actuator through an internally preset program. The electrical control box is equipped with a display screen, which is connected to the pressure sensor on the pressure block. This method is a common electrical control method on the market, so it will not be described in detail.

[0030] The beneficial effects of this utility model are:

[0031] In use, the fixing component and the testing component are symmetrically designed on the left and right sides of the testing platform to form two testing stations. This allows for simultaneous testing of the levers on both sides of the automotive combination switch, thereby improving the testing efficiency. During the testing process, different number of tests and forces can be set to compare and contrast the levers on both sides of the automotive combination switch, improving the accuracy of the test and facilitating its widespread use.

The test assembly includes an electric push rod 7 and a pressure block 8. The electric push rod 7 is vertically arranged on the upper and lower sides of the automotive combination switch, and the pressure block 8 is installed on the output end of the electric push rod 7. The fixing assembly includes a column 9, a support rod 10 and a positioning sleeve 11. The column 9 is fixedly installed on the upper end face of the base 1 and located on the left and right sides of the test platform 2. The support rod 10 is horizontally installed on the column 9 and located on the side closer to the test platform 2. There are two support rods 10 arranged parallel and symmetrically on the column 9. The positioning sleeve 11 is set on the support rod 10, and the lower end face of the positioning sleeve 11 is connected to the fixed end of the electric push rod 7. The positioning sleeve 11 and the support rod 10 are slidably connected, and the top of the positioning sleeve 11 is pre-threaded with a fastening bolt. The electrical control box 12 is located on one side of the base 1, and the electrical control box 12 is electrically connected to the test assembly.

[0043] In this embodiment:

[0044] First, move base 1 to the designated position;

[0045] Secondly, the experimenters selected a limiting rod 3 with a corresponding radius according to actual needs, and inserted the connecting block 4 into the connecting groove 5. After insertion, they rotated clockwise to form a threaded connection between the limiting rod 3 and the test platform 2, thereby ensuring the stability of the connection.

[0046] Next, the assembly of the automotive combination switch to be tested is set on the limit rod 3, and the automotive combination switch is fixed and limited by the limit platform 6. During the fixing, bolts can be inserted into the bolt holes corresponding to the limit platform 6 and the automotive combination switch to ensure the stability of the fixed and limited position of the automotive combination switch.

[0047] Then, the experimenters adjusted the position of the positioning sleeve 11 on the support rod 10 according to actual needs, so as to align the position of the test component with the position of the car combination switch lever. After the adjustment was completed, the positioning sleeve 11 and the support rod 10 were fixed together by fastening bolts.

[0048] Finally, the experimenters set the number of times and the force of the electric actuator 7 to operate according to the actual needs through the preset program inside the control box 12. After setting, the electric actuator 7 was started, causing the pressure block 8 to move up and down, thus conducting a durability test on the automotive combination switch lever. During the test, two sets of test components worked simultaneously, testing the levers on both sides of the automotive combination switch at the same time. The specific testing process was as follows: first, the upper pressure block 8 drove the lever downward, then the lower pressure block 8 drove the lever upward, and so on, to test the durability of the lever. When the durability test of the lever's up and down movement was completed, the durability test of the lever's back and forth movement could be conducted through the electric actuator 7 horizontally set on the external column 9. The testing method was the same as described above, so it will not be repeated here. This ensures the comprehensiveness of the lever's movement durability test, thereby ensuring the accuracy of the test results.
