Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1-3, the utility model provides a technical solution: an electric vehicle base with a front shock absorbing device, including two sets of wheel mounts 1 arranged symmetrically and horizontally. The opposite side walls between the seats 1 are symmetrically provided with pin shafts 2, and the movable key board 3 is sleeved on the pin shaft 2, and the top of the movable key board 3 is connected with the buffer spring 4, and the two groups of the buffer springs 4 The top of the top is connected by the mounting plate 5, one end of the two groups of pin shafts 2 is connected to the connecting rod 6, and the two groups of connecting rods 6 are connected through the pressure bearing plate 7, and the top of the pressure bearing plate 7 is buffered by two groups The part 8 is connected with the moving rod 9, and the left and right ends of the moving rod 9 are movably connected with the bottom of the movable key board 3 respectively.

Wherein, the buffer member 8 is formed by stacking multiple groups of arc-shaped steel plates 81 whose lengths are successively reduced, and the arc-shaped steel plates 81 are fixed by locking bolts 82, and the upper and lower side walls of the inner chamber of the moving rod 9 Limiting blocks 91 are symmetrically arranged, and telescopic rods 92 are horizontally arranged between the two groups of limiting blocks 91, and the left end of the telescopic rods 92 runs through the side wall of the moving rod 9 and extends to the outside thereof, and the telescopic rods 92 are located on the moving rod 9. A baffle 93 is connected to one end of the inner cavity, and a flange connected to the bottom of the movable keypad 3 is also connected to the end of the telescopic rod 92 outside the moving rod 9 .

Working principle: The body of the electric vehicle is fixed on the mounting plate 5, and two sets of buffer springs 4 are used to provide shock-absorbing buffer force for the body of the electric vehicle to improve the shock absorption performance of the electric vehicle. When the body of the electric vehicle is heavy, install The plate 5 is stressed and moves to contact with the pressure bearing plate 7, and the buffer space is further provided by two sets of buffer pieces 8 at the bottom of the pressure bearing plate 7.
