AI Technical Summary
Existing vehicle seat shock absorbers can only provide vertical shock absorption, and cannot provide shock absorption support in the vehicle's driving direction and other directions. They do not have shock absorption effects especially when emergency braking or acceleration, resulting in the passengers being unable to adjust in time in an emergency, which poses a major safety hazard.
A seat shock absorber device including a mounting frame, a vertical shock absorber assembly, a circumferential shock absorber assembly, a locking assembly and a buffer assembly are designed. The vertical shock absorbing component realizes vertical shock absorption through the annular frame and slide bar structure, and the circumferential shock absorption component realizes horizontal shock absorption through the bottom plate and damping bar structure. The buffering component automatically starts when the collision is dangerous, and the locking component quickly locks the seat when the collision occurs to prevent secondary collision.
It realizes shock absorption in both vertical and horizontal directions, improving the comfort and safety of passengers. In the event of a collision hazard, the buffer assembly will automatically start to reserve buffer space, and the locking assembly will quickly lock the seat to prevent secondary collisions.

[0001] The invention relates to the technical field of automobile manufacturing, and in particular to a vehicle seat shock absorbing device. Background Art
[0002] When a vehicle is driving, it is inevitable that there will be some bumps due to uneven roads or sudden acceleration and deceleration, which will cause the body to vibrate, and then be transmitted to the human body through the vehicle floor and seat cushions, causing vibration of the whole body.

[0033] The working principle of a vehicle seat shock absorbing device disclosed by the present invention is as follows:
[0034] (1) When the vehicle is in normal driving, as the road rises and falls, the seat 1 presses the conical seat 302 downward, and the conical seat 302 presses the second spring 404 downward. At the same time, the conical seat 302 presses the buffer block 304 in the radial direction of the annular frame 303, so that the first spring 307 is compressed. After compression, the vertical motion potential energy is converted into the elastic potential energy of the second spring 404 and the first spring 307, so as to achieve vertical shock absorption. When the seat 1 shakes forward and backward or left and right, the multiple damping rods 405 located around the annular frame 303 realize the shock absorption effect on the seat 1. At this time, the movable end of the damping rod 405 is fixed by the buffer assembly 6.
[0035] By starting the motor connected to the rotating shaft 311, the rotating shaft 311 is driven to rotate, and the rotating shaft 311 drives the gear 312 to rotate. The gear 312 drives the slide bar 306 to slide through the rack 309, and the slide bar 306 drives the buffer block 304 to slide. At this time, the first spring 307 is compressed, thereby realizing the adjustment of the shock absorption sensitivity. The shorter the first spring 307 is, the better the shock absorption effect is, and the longer the first spring 307 is, the worse the shock absorption effect is.
[0036] (2) When the vehicle radar detects that an object is rapidly approaching the vehicle, putting the vehicle in danger of collision, the vehicle radar controls the motor connected to the cam 612 to start, and the cam 612 rotates. The cam 612 pushes the slide 610 through the push rod 611, and the slide 610 drives the two slide blocks 605 to move toward each other through the inclined plate 613 arranged thereon. The slide block 605 drives the limit rod 602 to disengage from the through hole of the movable end of the damping rod 405 through the sliding frame 604. At this time, the movable end of the damping rod 405 is no longer fixed. During the retraction of the sliding frame 604, the slide column 608 thereon passes through the through hole on the fixed plate 603. Under the action of the spring, the slide column 608 bounces The cam 612 is inserted into the through hole of the fixed plate 603 to fix the position of the sliding frame 604. After contacting the limiting effect of the damping rod 405, the cam 612 continues to rotate, pushing the bottom plate 402 to move away from the position where a collision may occur, leaving more space to ensure the safety of the passengers. After the dangerous contact, the bottom plate 402 slides in the opposite direction. At this time, the movable end of the damping rod 405 pushes the second rotating plate 601 to rotate. The protrusion on the second rotating plate 601 pushes the sliding column 608 out of the through hole of the fixed plate 603. Under the action of the fourth spring 607, the limiting rod 602 extends into the through hole of the movable end of the damping rod 405 again, continues to fix the damping rod 405, and returns to the state of normal driving.
[0037] (3) When the vehicle collides and the pressure head 501 feels squeezed, the pressure head 501 drives the pressure rod 502 to slide, the pressure rod 502 pushes the first rotating plate 503 to rotate, and the first rotating plate 503 drives the locking rod 504 to slide, pulling the positioning column 505 out of the insertion rod 506. The insertion rod 506 is inserted into the bottom plate 402 under the action of the third spring 507, locking the bottom plate 402, and fixing the passengers as soon as possible to prevent collision with the vehicle body and causing secondary injuries.
