Description

Technical Field

[0001] The utility model relates to the technical field of automobile button testing, in particular to an automobile button testing device. Background Art

[0002] In the automotive industry, car buttons are an important component of vehicle interiors. They have diverse designs and functions and are found in multiple areas, including the steering wheel, center console, and doors. They control audio, air conditioning, windows, and lights. To ensure durability and reliability, car buttons require a press test during production. This test simulates daily user behavior of tapping car buttons to evaluate the durability of the buttons during long-term use. By simulating long-term and high-intensity use, the life of the buttons is tested to ensure that the buttons remain in good working condition even in harsh environments and under frequent use.

[0003] Traditional testing typically focuses on a single-point press in the middle of a key. This testing method fails to fully simulate the multi-point press conditions that may occur in actual use. Because drivers may apply force to different parts of the key during actual operation, this single-point force testing method may not fully reflect the force state of the key in actual use, thereby affecting the assessment of the key's durability and reliability.

[0004] In order to solve the above problems, this application proposes a car button testing device. Utility Model Content

[0005] Based on the technical problems existing in the background technology, the utility model proposes a car button testing device.

[0007] The support plate is provided with a multi-point switching pressing assembly and a reciprocating driver for driving the multi-point switching pressing assembly to move up and down;

[0008] The multi-point switching pressing assembly includes a fixed cylinder, a pressing column and a rod-type pressing piece. The fixed cylinder is located above the base and is driven by a reciprocating drive to move back and forth up and down. A through insertion channel is opened in the fixed cylinder, and a pressing column is installed in the insertion channel. The bottom end of the pressing column extends out of the insertion channel. Several evenly distributed rod-type pressing pieces are inserted on the pressing column, and the position of the rod-type pressing piece on the pressing column is adjustable.

[0009] Preferably, the rod-type pressing part includes a pressing rod, a sleeve, an elastic part and a bolt, and a plurality of evenly distributed pressing rods are inserted on the pressing column, and the bottom ends of the plurality of pressing rods extend to the bottom of the pressing column, and a plurality of evenly distributed sleeves are installed on the top of the pressing column, and the plurality of sleeves are respectively sleeved on a plurality of pressing rods, and an elastic part connected to the top end of the pressing rod is installed on the sleeve, and a locking part for limiting the pressing rod is installed on the sleeve.

[0010] Preferably, the elastic part includes a spring and an end block, the end block is installed on the top of the pressing rod, the bottom of the end block is installed with a spring sleeved on the pressing rod, and the bottom end of the spring is connected to the top of the sleeve shaft.

[0011] Preferably, the locking member comprises a bolt, and the outer periphery of the sleeve shaft is threadedly connected with the bolt which is pressed against the pressing rod.

[0012] Preferably, the reciprocating drive includes a motor, a turntable, a connecting rod, an assembly plate and a guide rail. The motor is installed on the side of the support plate, and the output end of the motor is connected to the turntable located above the base. The turntable is rotatably connected to an eccentrically set connecting rod, and a guide rail located below the turntable is installed on the support plate. The assembly plate is slidably installed on the guide rail. The bottom end of the connecting rod is rotatably connected to the side of the assembly plate, and the fixing cylinder is installed on the side of the assembly plate.

[0013] The above technical solution of the utility model has the following beneficial technical effects:

[0014] By setting up a multi-point switching pressing assembly and a reciprocating drive, the key to be tested can be placed on the base so that it is placed below the pressing column. First, the rod-type pressing part is pulled upward so that the pressing column can perform a pressing test on the key alone. Then, the fixed cylinder can be driven up and down by the reciprocating drive, and the key can be repeatedly pressed by the pressing column at the bottom of the fixed cylinder. In order to be able to perform multi-point pressing tests on the key, the rod-type pressing part on the pressing column can be adjusted so that the corresponding rod-type pressing part extends to the bottom of the pressing column. Then, the above steps are repeated again. The fixed cylinder is driven up and down by the reciprocating drive, and the key can be subjected to multi-point pressing tests by multiple rod-type pressing parts on the pressing column. This structure can simulate the single-point pressing and multi-point pressing conditions of the key in actual use, and comprehensively reflect the performance of the key under different force states. Compared with the traditional single-point pressing test, it provides data support for key quality testing that is more in line with actual application scenarios, and reduces the risk of product failure caused by key quality problems.
