Description
Technical Field
[0001] The utility model belongs to the field of automotive simulated collision tests, and particularly relates to a collision test fixture for simulating a vehicle body. Background Art
[0002] During the development of automotive seats, in order to test the safety of the seats, it is necessary to simulate the actual collision process to test the safety of the seats. Therefore, the installation of the seats needs to be the same as that in the actual vehicle, and environmental components that may affect the test results need to be installed. When conducting a collision test, the vehicle body needs to be installed on a sled collision test bench, and the actual collision process is simulated through a preset collision waveform to test the safety of the seats. However, due to the very tight vehicle body resources and the high cost of the vehicle body during the development stage, there is an urgent need for a collision test fixture that can replace the vehicle body. Summary of the Utility Model

The collision test fixture can install the front row seats, the center armrest, the rear row footrest, the rear row seats, the trunk and the environmental components according to the positional relationship of the actual vehicle. When conducting a collision test, by installing the installed collision test fixture on a sled collision test bench, the collision process can be reproduced to test the safety of the seats, solving the problem of tight vehicle body resources during the development stage and saving the test cost.
[0004] To achieve the above purpose, the utility model provides a collision test fixture for simulating a vehicle body, including a bottom plate. In the middle of the front end of the bottom plate, a simulated center armrest is installed. On the bottom plate on both opposite sides of the center armrest, there are multiple mounting columns for installing the front row seats. On the bottom plate behind the mounting columns, there are a rear row footrest, a main body frame and a trunk bottom plate. On the main body frame, there are a simulated rear row seat bottom plate for installing the rear row seats, a seat belt lock fixing point for installing the seat belt lock, a lower seat belt fixing point for installing the seat belt, and an upper seat belt fixing point. The seat belt lock fixing point is arranged at the middle position of the rear part of the simulated rear row seat bottom plate, and the position of the simulated rear row seat bottom plate relative to the seat belt lock fixing point has an avoidance opening. On both sides of the rear end of the simulated rear row seat bottom plate, there are lower seat belt fixing points, and at the top of the rear end of the main body frame, there is an upper seat belt fixing point.
[0005] As a further optimization, hooks are arranged in front of the simulated rear row seat bottom plate, a rotation center and a backrest lock hook are arranged on the main body frame on both sides behind the simulated rear row seat bottom plate. The seat cushion of the rear row seat is connected to the simulated rear row seat bottom plate through the hooks, and the backrest of the rear row seat is connected to the main body frame through the rotation center and the backrest lock hook.
[0006] As a further optimization, the main frame includes a base. Above the rear end of the base, there is a cross beam. On the opposite sides of the cross beam, there are vertical beams. At the rear end of the vertical beams, there are mounting brackets. Between the two mounting brackets on both sides, there is a luggage compartment floor board. The simulated rear seat floor board, seat belt lock fixing points, and seat belt lower fixing points are installed on the main frame through the base, and the seat belt upper fixing points are installed on the main frame through the mounting brackets.
[0007] As a further optimization, a plurality of child seat hooks are detachably connected to the main frame.
[0008] As a further optimization, the simulated center armrest, mounting posts, rear row footrest, and luggage compartment floor board are detachably connected to the floor board. The main frame is fixedly connected to the floor board. The simulated rear seat floor board, seat belt lock fixing points, seat belt lower fixing points, and seat belt upper fixing points are detachably connected to the main frame.
[0009] As a further optimization, the rotation center and the backrest hook are detachably connected to the main frame.
