Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat frame bodies, and more specifically to an axial high-frequency test tool for automobile seat frame suspension. Background Art

[0002] The so-called car seat is the seat you sit in when riding in a car. Car seats can be divided into split seats and long seats according to their shape; they can be divided into fixed, detachable and adjustable types according to their function; they can be divided into single, double and multi-person chairs according to the number of passengers. According to the performance of the seats, they have developed from the earliest fixed seats to the multi-functional power-adjustable seats, including air-cushion seats, electric seats, stereo seats, spirit recovery seats, and even electronically adjustable seats.

[0003] At present, the interior of the car seat frame body usually contains many parts, which are used for electrical control, seat heating, seat ventilation and seat adjustment functions. The parts and the car frame are usually assembled in a detachable manner. The car body will vibrate during driving, and the vibration will be transmitted to the driver and passengers through the car seat. Therefore, in order to ensure the stability of the parts installation and the comfort of the car during driving, and avoid abnormal noise of the car seat parts, the car seat frame body usually needs to be placed on a vibration test bench for vibration testing after assembly. However, the traditional vibration test bench usually completely fixes the car seat frame body when in use. At this time, the integrity of the car seat frame body and the vibration test bench increases, that is, the vibration effect acting on the car seat frame body is limited, which is not convenient for simulating the effect of bumps and vibrations encountered by passengers on the car seat during driving in real situations. In view of this, we propose a high-frequency test fixture for axial suspension of car seat frames. Utility Model Content

[0009] The utility model achieves the state of fixing one end of the seat assembly on the supporting platform and tilting the other end by means of the threaded cooperation of the fixing bolt with the fixing hole and the honeycomb hole. When conducting a vibration test, the tilted state of one end is beneficial to the generation of downward pressure at the front end under the action of inertia due to the rearward shift of the center during the vibration process, thereby achieving the real effect of simulating the bumps and vibrations encountered by the seat assembly during driving when a person is driving.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1.

When conducting a vibration test, the tilted state of one end is beneficial for generating downward pressure at the front end under the action of inertia due to the rearward movement of the center during the vibration process, thereby realizing the real effect of simulating the bumps and vibrations encountered by the seat assembly during driving when a person is driving, and solving the problem that the traditional vibration test bench is not convenient for simulating the bumps and vibrations encountered by the drivers and passengers on the car seats during driving under real conditions.
