Description

Technical Field

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

[0002] Given that rotary switches are more convenient to operate than traditional lever-type or manual pull-cord-type control switches, they are widely used in automobiles, such as in car air conditioning systems. When designing rotary switches, it is necessary to conduct operational durability tests on the rotary part to ensure that the service life of the rotary switch meets customer requirements.

[0003] Existing rotary switch durability testing devices are complex in structure and have a low degree of automation. Some testing devices even damage the knob structure, affecting the accuracy of switch durability tests and hindering their widespread use. Utility Model Content

[0004] 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 shortcomings of existing technologies, this utility model provides a durability testing device for automotive air conditioning rotary switches, aiming to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides a durability testing device for an automotive air conditioning rotary switch, comprising: a base, a fixing seat for fixing the automotive air conditioning rotary switch is provided on one side of the upper end face of the base, and a limit component is provided on the fixing seat; a testing part for testing the automotive air conditioning rotary switch is provided on the other side of the upper end face of the base; an adjustment component for adjusting the position is provided on one side of the fixing seat and the testing part; and an electrical control box is also included, located on one side of the base, and the electrical control box is electrically connected to the limit component, the testing part, and the adjustment component to form an automated structure.

[0006] The base design provides stable support for the entire device. The fixing base, in conjunction with the limiting components, secures and limits the type of automotive air conditioning rotary switch to be tested. After being fixed and limited, the automotive air conditioning rotary switch undergoes a durability test via the testing section. During use, the fixing base and testing section can be adjusted to the designated positions using the adjustment components. The electrical control box has a pre-set control program; during use, the limiting components, testing section, and adjustment components are integrated and operated through the control program, forming an automated function.

[0007] Preferably, the fixed seat has an "L" shaped cross-section, and the fixed seat and the base are slidably connected.

[0008] The "L"-shaped mounting base is a one-piece molded structure, and a slider and groove are pre-set between the mounting base and the base to form a sliding connection. This design also limits the movement of the mounting base, ensuring that it always moves along a preset path.

[0009] Preferably, the limiting assembly includes a pad, an electric actuator, and a limiting plate;

[0010] The pad is set on the upper end face of the horizontal axis of the "L"-shaped structure fixing seat;

[0011] The electric actuator is mounted on the upper end face of the vertical shaft of the "L"-shaped fixed base via a mounting bracket;

[0012] The limit plate is located at the output end of the electric actuator.

[0013] The pad is fixedly connected to the upper end of the horizontal axis of the "L"-shaped fixing base, and is used to limit the placement of the car air conditioning rotary switch. The mounting base is fixedly connected to the vertical axis of the "L"-shaped fixing base, ensuring the stability of the electric actuator. The electric actuator adopts an existing structure on the market, which drives the limiting plate to move vertically up and down.

[0014] Preferably, protective pads are provided on opposite sides of the pad and the limiting plate, and the protective pads are made of rubber.

[0015] When the pad and limit plate come into contact with the car air conditioning rotary switch, the rubber protective pad design prevents the limit plate from rigidly contacting the car air conditioning rotary switch to be tested, thus avoiding damage to the rotary switch due to compression. This provides a protective function for the car air conditioning rotary switch.

[0016] Preferably, the limiting plate is connected to the output end of the electric actuator via a bushing to form a detachable structure.

[0017] The bushing adopts a structure already available on the market, specifically model HD12B026, and has pre-set fastening bolts. This ensures the stability of the connection between the limit plate and the electric actuator, while also facilitating the disassembly and assembly of the limit plate. This allows for the selection of the appropriate limit plate model according to actual needs, avoiding limitations for experimental personnel during use, and also facilitating the replacement and maintenance of the limit plate in the future.

[0018] Preferably, the testing unit includes a support plate, a motor, and a pneumatic gripper;

[0019] The support plate is located above the base;

[0020] The motor is mounted on the upper surface of the support plate via a support base;

[0021] The pneumatic gripper is installed at the output end of the motor.

[0022] The support plate, together with the support base, provides fixed support for the motor. The motor adopts a commercially available structure and is used to drive the pneumatic gripper to rotate in both directions. The pneumatic gripper also adopts a commercially available structure and is used in conjunction with the motor to repeatedly twist the rotary knob switch of the car's air conditioning system, thereby accurately replicating the practical use of the knob and facilitating precise testing of the knob's durability.

[0023] Preferably, the pneumatic gripper is detachable from the motor output end via a bushing.

[0024] The bushing adopts a structure already available on the market, specifically model CFC65×80-14 / 40, and has pre-set fastening bolts. This ensures the stability of the connection between the pneumatic gripper and the motor output end, while also facilitating the disassembly and assembly of the pneumatic gripper. This allows for the selection of the appropriate model of pneumatic gripper according to actual needs, avoiding limitations for experimental personnel during use, and also facilitating the replacement and maintenance of the pneumatic gripper in the future.

[0025] Preferably, the adjustment assembly includes adjustment rod a and adjustment rod b;

[0026] The adjusting rod a is horizontally mounted on the base, located on the left side of the fixed seat, and its output end is connected to the outer surface of the left side of the fixed seat;

[0027] The adjusting rod b is vertically positioned inside the base, and its output end passes through the base and connects to the lower end face of the support plate.

[0028] Adjusting rods a and b are commercially available electric actuators, used to drive the fixed base to move laterally left and right, and the support plate to move longitudinally up and down, respectively. Both the fixed base and the support plate are equipped with displacement sensors to monitor changes in object displacement in real time, providing precise feedback to the control system and enabling precise control of the motion trajectory and position of the fixed base and support plate. This method is common knowledge in the field, and its specific working principle will not be elaborated further.

[0029] The beneficial effects of this utility model are:

[0030] When in use, this utility model has a simple overall structure, which not only reduces manufacturing costs but also facilitates subsequent maintenance procedures. Furthermore, during use, the limit components, testing section, and adjustment components are integrated and controlled through the control program inside the electrical control box, forming an automated function that improves testing efficiency to a certain extent and is conducive to its widespread use.

[0040] Please see Figures 1 to 4This utility model provides a durability testing device for a rotary car air conditioner switch, comprising: a base 1, a fixing seat 2 for fixing the rotary car air conditioner switch on one side of the upper end face of the base 1, and a limit component on the fixing seat 2; a testing part for testing the rotary car air conditioner switch on the other side of the upper end face of the base 1; an adjustment component for adjusting the position on one side of the fixing seat 2 and the testing part; and an electrical control box 12 located on one side of the base 1, electrically connected to the limit component, the testing part, and the adjustment component to form an automated structure. The fixing seat 2 has an "L"-shaped cross-section and is slidably connected to the base 1. The limit component includes a pad 3, an electric push rod 4, and a limit plate 5. The pad 3 is disposed on the upper end face of the horizontal axis of the "L"-shaped fixing seat 2, and the electric push rod 4 is mounted on the "L"-shaped fixing seat 2 via a mounting base 401. The upper end face of the vertical axis of the ""-shaped fixed base 2 has a limiting plate 5 set at the output end of the electric push rod 4. The pad 3 and the limiting plate 5 are both provided with protective pads 6 on opposite sides, and the protective pads 6 are made of rubber. The limiting plate 5 is connected to the output end of the electric push rod 4 via a bushing to form a detachable structure. The test part includes a support plate 7, a motor 8 and a pneumatic gripper 9. The support plate 7 is located above the base 1. The motor 8 is installed on the upper end face of the support plate 7 via a support seat 801. The pneumatic gripper 9 is installed on the output end of the motor 8. The pneumatic gripper 9 is connected to the output end of the motor 8 via a bushing to form a detachable structure. The adjustment component includes an adjustment rod a10 and an adjustment rod b11. The adjustment rod a10 is horizontally set on the base 1 and located on the left side of the fixed base 2. Its output end is connected to the outer surface of the left side of the fixed base 2. The adjustment rod b11 is vertically set inside the base 1. Its output end passes through the inside of the base 1 and is connected to the lower end face of the support plate 7.

[0041] In this embodiment:

[0042] First, move base 1 to the designated position;

[0043] Secondly, select the corresponding model of limit plate 5 and pneumatic gripper 9 according to actual needs, and install them on the output end of electric push rod 4 and motor 8 through bushings;

[0044] Next, place the car air conditioning rotary switch to be tested on the upper surface of the pad 3. After placement, activate the electric push rod 4 on the top of the mounting base 401, so that the electric push rod 4 drives the limiting plate 5 to move downward until the limiting plate 5 contacts the car air conditioning rotary switch and fixes it in place. When in contact, the design of the rubber protective pad 6 prevents the limiting plate 5 from rigidly abutting against the car air conditioning rotary switch to be tested, which would cause the rotary switch to be tested to be squeezed and damaged, thus providing a protective function for the car air conditioning rotary switch.

[0045] Then, after the car air conditioning knob switch to be tested is fixed and limited, the test unit and adjustment components are integrated and controlled by the control program inside the electrical control box 12. During operation, the adjustment rod a10 is activated first, so that the adjustment rod a10 drives the fixed seat 2 to move laterally along the upper surface of the base 1 to the designated position. Then the adjustment rod b11 is activated, so that the adjustment rod b11 drives the support plate 7 to move upward and adjust it to the designated height, so that the pneumatic gripper 9 is parallel to the car air conditioning knob switch to be tested on the upper surface of the pad 3. After paralleling, the fixed seat 2 is further driven to the right by the above means until the pneumatic gripper 9 can clamp the car air conditioning knob switch to be tested on the upper surface of the pad 3.

[0046] Finally, after the pneumatic gripper 9 clamps the car air conditioning knob switch to be tested, the motor 8 on the support base 801 is started, so that the motor 8, together with the pneumatic gripper 9, repeatedly twists the car air conditioning knob switch, thereby accurately restoring the practical use of the knob and facilitating accurate testing of the knob's durability.

[0047] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
