Embodiment 1

[0031] According to the present invention, when the power supply 20 is turned on and the vehicle motor is in operation, the following conditions are obtained:

[0032] The controller 18 receives the working signal of the vehicle traveling motor 19, and cuts off the power supply of the adjusting motor 6 by the controller 18, thereby avoiding the operation of the adjusting motor 6;

[0033] On the basis that the power supply 20 is turned on, and the motor of the vehicle is stopped, the following conditions are obtained:

[0034] The controller 18 receives the stop working signal of the vehicle traveling motor 19, and the controller 18 starts the adjustment motor 6, and realizes automatic adjustment according to the load condition of the vehicle.

Embodiment 2

[0036] When the power supply 20 was turned off (i.e. the vehicle was at rest), the controller 18 received the stop signal of the vehicle running motor 19. At this moment, the following two situations would occur:

[0037] The first case: when the heavy load of the vehicle increases, the entire vehicle frame 1 is pressed down, and when the upper limit switch 16 on the left side of the limit groove 12 contacts the limit block 13, the upper limit switch 16 transmits a signal to the controller 18 , the controller 18 gives a reverse signal to the adjustment motor 6, and drives the drive screw 8 to reverse. At this time, the drive nut 7 drives the connecting plate 4 and the shock absorber 3 fixed on the connecting plate 4 to drive the screw 8 The end of the motor moves to adjust the inclination angle of the shock absorber 3, thereby improving the hardness of the vehicle shock absorber.

[0038] The second situation: when the load of the vehicle is gradually reduced, the entire vehic...

Embodiment 3

[0040] According to the second embodiment, the present invention can make the following two adjustments in the two situations in the second embodiment.

[0041]The first situation: when the above-mentioned adjustment is made by adjusting the motor 6, in order to make the drive nut 7 move to the top of the drive screw 8, the drive nut 7 will not be "hardly touched" with the vehicle frame 1, so that the drive wire The left end of the rod 8 is provided with a top limit switch 14. When the drive nut 7 touches the top limit switch 14, the top limit switch 14 will give a stop signal to the controller 18, and the controller 18 will control and adjust the motor 6 stop working.

[0042] The second situation: when moving to the end of the transmission screw 8, in order to prevent the connecting plate 4 from "hard hitting" with the vehicle frame 1, an end limit switch 15 is set at the end of the transmission screw 8. When the connecting plate 4. When the end limit switch 15 is touched, ...

Abstract

The invention discloses a vehicle suspension rigidity adjusting device with the automatic reset function. The vehicle suspension rigidity adjusting device comprises a vehicle frame and a seat bucket fixed to the vehicle frame. A rear bottom fork is installed on the vehicle frame. Two rails are arranged on the two inner sides of the vehicle frame respectively. A connecting plate is movably arranged between the two rails. The two ends of the connecting plate are each fixedly provided with a shock absorber. The bottom ends of the two shock absorbers are fixed to the rear bottom fork. A transmission nut is fixed to the connecting plate. A transmission lead screw is arranged on the vehicle frame. One end of the transmission lead screw penetrates through the transmission nut and the connecting plate to be connected with the vehicle frame. The other end of the transmission lead screw is connected with the output end of an adjusting motor. A limiting groove is formed in one side of the vehicle frame. A limiting block is movably arranged in the limiting groove. The bottom end of the limiting block is fixedly connected with the rear bottom fork through a pull rod. A controller is fixed in the seat bucket. According to the vehicle suspension rigidity adjusting device, the structure is simple, automatic adjustment can be achieved according to vehicle load conditions, and the vehicle suspension rigidity is made to be always in the optimum state, so that the service life of the vehicle is greatly prolonged, and the driving comfort is improved.

Description

technical field [0001] The invention relates to a vehicle adjusting device, in particular to a vehicle shock-absorbing hardness adjusting device with automatic reset, which mainly automatically adjusts the shock-absorbing hardness of an electric vehicle. Background technique [0002] The structure of the known vehicle shock-absorbing device is composed of a spring and a damper. The defect of the device is that the hardness of the shock absorber is fixed and cannot be adjusted with the load of the vehicle, resulting in serious bumps of the vehicle under light load, and the shock absorber is compressed to the bottom under heavy load, resulting in failure of the shock absorber and fatigue damage of the shock absorber spring. A few days ago, a kind of adjustment device about the vehicle also appeared on the market, such as figure 1 as shown, figure 1 It is a published patent (patent number: 201220456053.0; patent name: a vehicle shock absorber hardness adjustment device; publ...
