Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments described in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] An embodiment of the present invention provides an electronic brake switch suspension adjustment device, which realizes vehicle parking and height adjustment by setting a serial parking control system.

[0026] like Figures 1 to 7As shown, the electronic brake switch suspension adjustment device includes an electronic brake switch assembly, wherein the electronic brake switch assembly includes a control box 1 and an electronic brake switch 11. The control box 1 is installed on the center console of the car driving control position, and an opening is provided on the top of the control box 1. The electronic brake switch 11 is exposed in the opening. The opening is provided with a reserved space for the electronic brake switch 11 to rotate forward and backward and a space for the electronic brake switch 11 to move left and right. The electronic brake switch 11 can slide and rotate left and right in the opening. The bottom of the electronic brake switch 11 is coaxially connected to a driving gear 12, and the center of the driving gear 12 rotates around a driving wheel shaft 13. The two ends of the driving wheel shaft 13 are respectively provided with spring chambers 14, and the two ends of the driving wheel shaft 13 are connected to the spring chambers 14 through reset springs. The rotation and left and right movement of the electronic brake switch 11 are transmitted to the driving gear 12. The end of the driving wheel shaft 13 is sleeved in the reset spring, and the spring chamber 14 is correspondingly fixed on the inner walls on both sides of the control box 1. A photoelectric sensor 15 is arranged behind the electronic brake switch 11, and the photoelectric sensor 15 is arranged on the inner wall of the bottom of the control box 1. The photoelectric sensor 15 is used to sense the forward and backward rotation state of the electronic brake switch 11. The driving gear 12 can be rotatably engaged with a left composite wheel 21 and a right composite wheel 22 arranged in parallel. The left composite wheel 21 is arranged in the left front of the driving gear 12, and the right composite wheel 22 is arranged in the right front of the driving gear 12 and is rotatably connected to the inner wall of the control box 1 through the composite wheel shaft 2. By toggling the electronic brake switch 11 left and right, the driving gear 12 is adjusted to mesh with the left composite wheel 21 or the right composite wheel 22 for transmission. The left composite wheel 21 and the right composite wheel 22 are provided with meshing teeth on the side facing the driving gear 12, and the meshing teeth enable the driving gear 12 to transmit torque when meshing with the left composite wheel 21 or the right composite wheel 22. The meshing teeth of the left composite wheel 21 are provided with a pressure sensor 23, and the pressure sensor 23 is used to sense the meshing state. The meshing teeth of the right composite wheel 22 are provided with a pressure sensor 23, and the pressure sensor 23 is used to sense the meshing state. An angle encoder 24 is provided at one end of the composite wheel shaft 2, and the angle encoder 24 obtains the rotation angle information of the composite wheel shaft 2 by rotating, and converts the collected analog signal into a digital signal through the control system.

[0027] It also includes a driving unit, which includes a hydraulic driving module, an adjustment module, a hydraulic suspension assembly, and a hydraulic brake assembly. The hydraulic driving module is arranged at the middle and rear part of the automobile chassis, and includes a hydraulic oil tank 3, a pressure regulating oil pump 31, a distribution valve 32, and a driving oil pipe 33. The adjustment module includes an adjustment cylinder 4. The hydraulic oil tank 3 adjusts the hydraulic oil pressure through the pressure regulating oil pump 31, and the distribution valve 32 realizes the braking and height adjustment functions by connecting the corresponding driving oil pipe 33. The driving oil pipe 33 includes a brake oil pipe 7 and a height adjustment oil pipe, and the height adjustment oil pipe is used to adjust the adjustment cylinder 4. It also includes a hydraulic suspension assembly and a hydraulic brake assembly. The hydraulic suspension assembly includes a suspension frame 5, a support rod 6, and a wheel hub frame 61. The suspension frame 5 is used to support the chassis body and the wheel hub frame 61, and the wheel hub frame 61 is fixed below the suspension frame 5 to fix the wheel hub. The suspension frame 5 is divided into a right suspension 51 and a left suspension 52. The height of the suspension frame 5 is adjusted by a support rod 6 and an adjustment cylinder 4. The support rod 6 is an elastic support rod 6. The top end of the support rod 6 is connected to the side wall of the suspension frame 5, and the bottom end of the support rod 6 is connected to the top end of the hub frame 61. The support rod 6 is used to provide support force as a buffer for the suspension frame 5 when the adjustment cylinder 4 is adjusted. The adjustment cylinder 4 is connected to the height adjustment oil pipe through the hub frame 61. The height adjustment oil pipe is connected to the hub frame 61. One end of the height adjustment oil pipe is connected to the distribution valve 32, and the other end is connected to the oil inlet set in the hub frame 61. The brake oil pipe 7 is connected to the distribution valve 32 at one end and to the brake installed on the wheel hub at the other end to provide a flow path for the brake.

[0028] The pressure regulating oil pump 31 in the hydraulic oil tank 3 is a plunger pump, which is driven by an electromagnetic driver to perform pressure feeding. The distribution valve 32 is an electromagnetic multi-channel distribution valve, and the distribution scheme is set by the control system to give the distribution valve 32 driver to control the opening and closing state of the electromagnetic multi-channel distribution valve 32, and adjust the flow pressure in the driving oil pipe 33. A diverter valve is set in the suspension frame 5, and the diverter valve is connected to the two groups of the adjustment oil cylinders 4. The diverter valve transmits the oil pressure introduced through the driving oil pipe 33 to the adjustment oil cylinder 4.

[0029] During the parking process, by turning the electronic brake switch 11 in the control box 1, the photoelectric sensor 15 obtains the parking brake signal and enters the pre-parking state. After turning it twice in a row, it enters the parking mode. The control system adjusts the hydraulic oil tank 3. The parking signal mobilizes the driver of the pressure regulating oil pump 31 to provide pressure. The control system adjusts to the braking state through the driver through the distribution valve 32. The brake oil pipe 7 receives the oil pressure and acts on the brake to perform parking braking. During the parking process, by turning the electronic brake switch 11 in the control box 1 and controlling the electronic brake switch 11 to move left and right, the driving gear 12 is meshed with the left composite wheel 21 or the right composite wheel 22. Taking the meshing of the driving gear 12 with the left composite wheel as an example, the rotation angle of the electronic brake switch 11 and the left composite wheel axle 2 is captured by the angle encoder 24, and the photoelectric sensor 15 captures the rotation effect data of the electronic brake switch 11. The return spring in the spring chamber 14 bounces and resets the drive wheel shaft 13, driving the drive gear 12 to disengage from the left composite wheel 21. After the control system confirms, the control system sends a control signal to the hydraulic oil tank 3 for adjustment, and controls the pressure through the driver of the pressure regulating oil pump 31. At the same time, the control system sends the adjustment signal of the distribution valve 32 to the driver of the distribution valve 32. By adjusting the driving state of the driver of the distribution valve 32, the distribution valve 32 controls the hydraulic oil to quantitatively provide oil pressure for the brake through the brake oil pipe 7 after adjustment by the driver. The quantitative flow of the oil circuit flows through the left driving oil pipe 33 and flows into the wheel hub frame 61. Through the diverter valve set in the wheel hub frame 61, it enters the adjustment cylinder 4 with the oil pressure in the distribution oil circuit respectively. The adjustment cylinder 4 on the left suspension 52 side is lifted to form the chassis slope. The driver of the distribution valve 32 is connected to the right driving oil pipe 33 for adjustment, and the adjustment oil cylinder 4 connected between the right wheel hub frame 61 and the right suspension 51 is pressurized under the action of gravity so that the hydraulic oil in the oil circuit flows back from the adjustment oil cylinder 4 to the hydraulic oil tank 3, completing the suspension adjustment. This makes the vehicle floor tilt and assists people to get on and off the vehicle.

[0030] To reset the roll, by toggling the electronic brake switch 11, the photoelectric sensor 15 captures the toggling operation, and the photoelectric sensor 15 sends a reset signal to the control system, which sends a control signal to the pressure regulating oil pump 31. The pressure regulating oil pump 31 adjusts the pump body, and the control system adjusts the driver of the distribution valve 32, so that the drive oil pipe 33 on the left side keeps the passage to unload the oil pressure, and the distribution valve 32 at the branch end of the brake oil pipe 7 remains closed. The adjustment cylinder 4 under the left suspension frame 5 refluxes, so that the left side height is restored to the initial set height. After reaching the set height, the distribution valve 32 closes the drive oil pipe 33 branch on the left side. At the same time, by adjusting the driver of the distribution valve 32, the drive oil pipe 33 on the right side is opened, and the pressure regulating oil pump 31 is driven to pressurize. After pressurization, the adjustment cylinder 4 under the right suspension 51 is lifted, and the right suspension 51 on the right side is lifted to the initial set height, completing the roll reset.

[0031] To release the parking brake lock, by toggling the electronic brake switch 11, the photoelectric sensor 15 transmits the toggling detection signal to the control system, and the control system opens the branch of the brake oil pipe 7 in the driver of the distribution valve 32, and at the same time, the driver of the pressure regulating oil pump 31 drives the pressure relief. By relieving the pressure on the brake, the brake's restriction on the wheel hub is released, so that the wheel hub can resume its driving ability.
