Problems solved by technology

The driver of the excavator has to bear the severe vibration generated by the body during work. This vibration will cause discomfort to the driver's body, increase the driver's fatigue, and affect the driver's work.
At present, it is generally used to install a mechanical spring under the driver's seat for shock absorption, but due to the fixed stiffness of the mechanical spring, it cannot take into account the shock absorption requirements under various vibration intensities, and only one degree of freedom in the up and down direction can be realized. Shock, can not reduce the inclination of the seat, so the effect is not ideal

Embodiment 1

[0033] Such as figure 1 , figure 2 , image 3 As shown, in the present embodiment, the mechanical spring type electromagnetic damper 10 includes two springs 11, and the bottom 2 of the seat 1 in the cab of the motor vehicle is divided into the first area 21 and the second area 21 with the same area by the first central axis 3. In the second area 22, respective one ends of the two springs 11 are respectively fixed in the first area 21 and in the second area 22, and the other ends of the two springs 11 are respectively fixed on the base plate 6 of the cab of the motor vehicle, and the two springs 11 Magnetic cores 12 are respectively arranged inside, and the two springs 11 are respectively electrically connected to the controller 30, and the controller 30 controls the stiffness of the two springs 11 by controlling the current intensity of the two springs 11 respectively according to the electrical signal of the inclination sensor.

Embodiment 2

[0035] Such as Figure 4 , Figure 5 , Figure 6 As shown, in the present embodiment, the mechanical spring type electromagnetic damper 10 includes four springs 41, 42, 43, 44, and the bottom 2 of the seat 1 of the driver's cab of the motor vehicle is defined by the first central axis 3 and the first central axis. The second central axis 4 perpendicular to the axis 3 is divided into four areas 9 with equal areas, and the respective one ends of the four springs 41, 42, 43, 44 are respectively fixed in the four areas 9, and the four springs 41, 42, 43, The other ends of 44 are respectively fixed on the bottom plate 6 of the cab of the motor vehicle, and the insides of the four springs 41, 42, 43, 44 are respectively provided with magnetic cores 12. The four springs 41, 42, 43, 44 are electrically connected with the controller 30 respectively, and the controller 30 controls the current intensity of the four springs 41, 42, 43, 44 according to the electric signal of the inclinat...

Abstract

The invention provides a seat shock-absorbing device on a motor vehicle, which comprises a controllable damping device, an inclination angle sensor and a controller, wherein the controllable damping device is mounted between the bottom of a seat in a cab of the motor vehicle and a bottom plate of the cab of the motor vehicle; the inclination angle sensor is mounted at the bottom of the seat, and used for converting an inclination angle and an inclination direction of the seat into an electrical signal; and the controller is electrically connected with the damping device and the inclination angle sensor, and is used for receiving the electrical signal of the inclination angle sensor, and controlling the rigidity of the controllable damping device according to the inclination angle and the inclination direction of the seat, so as to reduce the inclination magnitude of the seat. In the seat shock-absorbing device on the motor vehicle, the rigidity of the controllable damping device can be adjusted by the controller, so that shock-absorbing requirements at different shock strength can be met; the seat shock-absorbing device is better in shock-absorbing effect; and the seat shock-absorbing device on the motor vehicle ensures the stability of the seat in a working process of the motor vehicle, and guarantees the safety and normal working of a driver.

Description

technical field [0001] The invention relates to the arrangement of seats on a vehicle, in particular to a seat shock absorbing device on a motor vehicle. Background technique [0002] Excavator is a kind of construction machinery, which is widely used in construction, road, mine, port and other engineering fields. The main function of the excavator is to carry out excavation work. The vast majority of today's excavators are hydraulic excavators. Hydraulic excavators generally include working devices, slewing devices and traveling devices. [0003] As a kind of construction machinery, excavator has a relatively harsh working environment. The driver of the excavator has to bear the severe vibration generated by the body during work. This vibration will cause discomfort to the driver's body, increase the driver's fatigue, and affect the driver's work. At present, it is generally used to install a mechanical spring under the driver's seat for shock absorption, but due to the...
