Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import by those skilled in the art without departing from the spirit of this application and is therefore not limited to the specific implementations disclosed below.
As shown in fig. 1, 2, the present application provides a vehicle seat suspension including: a first suspension frame assembly 100, a second suspension frame assembly 200, a cross arm 300, and a weight adjustment mechanism assembly 400.
The first suspension frame assembly 100 and the second suspension frame assembly 200 are arranged oppositely, the first suspension frame assembly 100 is used for arranging a seat cushion assembly to facilitate passengers or drivers to sit on the seat cushion, and the second suspension frame assembly 200 opposite to the first suspension frame assembly 100 fixes the seat inside the vehicle body through connection with the vehicle body.
The cross arm 300 is disposed between the first suspension frame assembly 100 and the second suspension frame assembly 200. Specifically, the first suspension assembly 100 and the second suspension assembly 200 are provided with symmetrical fixing members, and the cross arm 300 is fixed to the fixing members. The first suspension frame assembly 100 and the second suspension frame assembly 200 are provided with sliding grooves (not shown) for the cross arm 300 to extend and retract, and the cross arm 300 can slide in the sliding grooves at a bumpy road section of the vehicle, so that the distance between the first suspension frame assembly 100 and the second suspension frame assembly 200 is adjusted, and the buffer between the first suspension frame assembly 100 and the second suspension frame assembly 200 is provided for the vehicle during the driving process at the bumpy road section.
The weight adjustment mechanism assembly 400 is used to adjust the relative distance that the first suspension frame assembly 100 moves toward the second suspension frame assembly 200 when occupants of different weights sit on the seat cushion. Taking the environment when the vehicle is stationary as an example, for example, when occupants having weights of 70kg and 90kg, respectively, are seated on the seat cushion on the first suspension frame assembly 100, the 70kg occupant lowers the first suspension frame assembly 100 by a distance of 3cm, and the 90kg occupant lowers the first suspension frame assembly by a distance of 5 cm. The distance difference of 2cm between the occupants of 70kg and 90kg is adjusted by setting parameters of the weight adjusting mechanism assembly 400 so that the relative distance between the first suspension frame assembly 100 and the second suspension frame assembly 200 due to the weight difference between the occupants is substantially the same when the vehicle is stationary, and thus the degree of jounce is substantially the same for occupants of different weights during the running of the vehicle.
Referring to fig. 3 to 8, the weight adjustment mechanism assembly 400 includes: a prestress adjusting means 410, an elastic member 420, and a guide member 430.

It should be noted that the prestress of the elastic member is the gravity difference between the passengers for adjusting the weight difference, that is, the elastic member generates a prestress against the gravity in the gravity direction of the passengers under the static environment of the vehicle. When the distance between the first suspension frame assembly and the second suspension frame assembly changes, no matter the distance changes caused by vehicle jolt or the distance changes caused by movement of passengers, the elastic part further generates elastic deformation on the basis of prestress at the moment, and the elastic part also can be regarded as the change of the prestress generated by the elastic part, wherein the change of the prestress is the elastic deformation for increasing or releasing the elastic part.
In this embodiment, the elastic member 420 is a torsion bar spring, and the torsion bar spring increases or releases a torsional deformation when a distance between the first suspension frame assembly 100 and the second suspension frame assembly 200 is changed. Fig. 2 shows the structure and arrangement of the prestress adjusting device when the elastic member is a torsion bar spring.
