Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to a device for testing the durability of automotive hatchback interior panels. Background Technology

[0002] A hatchback is a common type of tailgate for automobiles. A hatchback interior panel refers to the interior trim installed on the hatchback door, primarily used to conceal the sheet metal and mounted components, while also providing aesthetics and functionality. The design and manufacture of hatchback interior panels require consideration of various factors, including material selection, processing techniques, and structural optimization.

[0003] During the production and processing of hatchback doors, durability tests are required to see if the plastic parts will detach from the sheet metal or loosen under long-term use.

[0004] Therefore, how to provide a durability testing device for automotive hatchback interior panels has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is how to provide a device for testing the durability of automotive hatchback interior panels.

[0006] To achieve the above objectives, this utility model provides a durability testing device for automotive hatchback interior panels, comprising: a base, on which a hatchback body is disposed, and an electric push rod for durability testing is disposed between the base and the hatchback body. The hatchback body is mounted on the base via a support mechanism, and the support mechanism and the base are detachably connected.

[0007] The base design provides stable support for the entire device. The hatchback body adopts a structure already available in the market, so it will not be described in detail. The electric actuator, also using a commercially available structure, applies a force perpendicular to the hatchback interior panel assembly to the handle box on the interior panel of the hatchback body. Starting from the fully open position and ending 30mm from the door lock position, it simulates the opening and closing of a car hatchback, thereby testing the durability of the interior panel on the hatchback. The detachable design facilitates not only transportation but also subsequent storage and maintenance.

[0008] Preferably, the base is made of stainless steel.

[0009] The stainless steel base has excellent corrosion resistance, thus extending its service life.

[0010] Preferably, the hatchback body is pre-installed with an interior trim panel and a hydraulic rod.

[0011] Interior trim panels and hydraulic struts are auxiliary components on the hatchback body. This is common knowledge in the field, so it will not be described in detail.

[0012] Preferably, the electric push rod is inclinedly mounted on the base, with its fixed part installed at the bottom of the base via a mounting block, and its movable part connected to the interior panel on the hatchback body.

[0013] A pivot is provided between the electric actuator fixing part and the mounting block to form a movable structure, which makes it easy to adjust the angle of the electric actuator according to actual needs.

[0014] Preferably, the support mechanism includes a support frame, a connector, and an auxiliary rod.

[0015] The support mechanism is designed to mount the hatchback door body onto the support frame, and the support frame, connectors, and auxiliary rods adopt existing structures in the field.

[0016] Preferably, the support frame is vertically arranged on the upper surface of the base, and bolt holes are pre-set at the connection between the support frame and the base, and fixing bolts are provided in the bolt holes.

[0017] The design of bolt holes and fixing bolts allows the support frame and base to form a detachable structure, while ensuring the stability of the connection between the support frame and base.

[0018] Preferably, the connector is located on one side of the support frame and is movably connected to the hydraulic rod on the hatch body.

[0019] The design of the movable connection enables the hatchback body to simulate opening and closing functions, thereby testing the durability of the interior panels on the hatchback body.

[0020] Preferably, the auxiliary rod is designed with an inclined shape, with one end connected to the bottom of the base and the other end connected to the support frame. Bolt holes are pre-set at the connection points between the auxiliary rod and the base and the support frame, and fixing bolts are installed in the bolt holes.

[0021] The auxiliary rods provide auxiliary support to the support frame, thus ensuring the stability of the support frame in fixing the hatchback door body.

[0022] Preferably, it also includes an electrical control box, which is located on one side of the base and is electrically connected to the electric actuator.

[0023] The electrical control box adopts the existing structure in the market and the electrical connection design, which makes it easy for users to preset the parameters of the durability of the interior panel on the hatch body. The specific parameters are: the switching frequency is 1-6 times / min, one opening and one closing is counted once, and the number of tests can be set according to actual needs, with a setting range of 0-99999 times.

[0024] The beneficial effects of this utility model are:

[0025] When in use, the durability test of the interior trim panel on the car hatchback is carried out automatically by an electric push rod, demonstrating the automation level of the device. At the same time, the design of the support mechanism when not in use facilitates movement and transportation, as well as subsequent storage and maintenance, thus promoting its widespread use.
