Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments. In the following description, specific details such as specific configurations and components are provided merely to facilitate a thorough understanding of embodiments of the invention. It will therefore be apparent to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.
Referring to fig. 1, a first embodiment of the present invention provides an automotive hydraulic system, comprising:
an oil tank 1;
a first hydraulic cylinder 2 which is communicated with the oil tank 1 through a first pipeline 3, wherein the first pipeline 3 is provided with a first one-way control valve 31;
the second hydraulic cylinder 4 is communicated with the oil tank 1 through a second pipeline 5, and the second pipeline 5 is provided with a stop valve 51; the first hydraulic cylinder 2 is communicated with the second hydraulic cylinder 4 through a third pipeline 6, the third pipeline 6 is provided with a second one-way control valve 61, and the first one-way control valve 31 and the second one-way control valve 61 are oppositely arranged;
a wheel 7 slidably disposed on the second hydraulic cylinder 4 via a tire support rod 8;
a first driving motor 9 connected with a first piston of the first hydraulic cylinder 2;
and the output shaft of the second driving motor and the wheel 7 coaxially rotate, and the wheel 7 can roll along the preset direction by being driven by the second driving motor.
When the first drive motor 9 rotates in the first direction, the first piston of the first hydraulic cylinder 2 moves in a direction away from the bottom of the first hydraulic cylinder 2, so that the volume of the oil chamber at the lower end of the first piston increases, a partial vacuum is formed, and the first one-way control valve 21 is opened and the second one-way control valve 61 is closed. When the first check valve 21 is opened, the oil in the oil tank 1 is sucked into the first hydraulic cylinder 2 through the first pipe 2.
When the first drive motor 9 rotates in a second direction opposite to the first direction, the first piston in the first hydraulic cylinder 2 moves toward the bottom of the first hydraulic cylinder 2, and the pressure in the oil chamber at the lower end of the first piston increases, so that the first one-way control valve 21 is closed and the second one-way control valve 61 is opened. When the second one-way control valve 61 is opened, the oil in the first hydraulic cylinder 2 flows into the second hydraulic cylinder 4 through the third pipeline 6, and the oil level in the second hydraulic cylinder 4 gradually rises, so that the wheels 7 arranged on the second hydraulic cylinder 4 can rise or fall along with the change of the oil level in the second hydraulic cylinder 4.
As the oil level in the second hydraulic cylinder 4 increases, the wheels 7 gradually approach the ground and contact the ground, and when the oil level in the second hydraulic cylinder 4 increases to a certain level, the automobile is completely jacked up by the automobile hydraulic system and separated from the ground. At this time, the second driving motor drives the wheels 7 to move towards the parking space by controlling the second driving motor, so that the automobile is towed into the parking space. After the vehicle is towed into the parking space, the stop valve 51 in the second pipeline 5 is controlled to be opened, the oil level in the second hydraulic cylinder 4 is lowered, and the vehicle is further restored to a ground contact state.
When the vehicle is driven off the parking space, the first driving motor 9 is controlled to lift the vehicle off the ground, and the operation of this part is the same as the above-described mode, and will not be described here again. When the second drive motor is controlled after the vehicle is lifted, the second drive motor is controlled to rotate in a direction opposite to the rotation direction, and the wheels 7 are driven to roll in a direction away from the parking space.
The shutoff valve 51 in the first embodiment of the invention has a water pump suction effect and can suck the oil in the second hydraulic cylinder 4 into the oil tank 1.
According to the automobile hydraulic system provided by the first embodiment of the invention, the problem that a vehicle cannot normally enter into parking because the length of a reserved parking space is short in the lateral parking process can be solved.

The first tire auxiliary supporting rod 101 and the second tire auxiliary supporting rod are arranged to ensure that the wheels 7 of the automobile hydraulic system run along a straight line completely when rolling, and deflection can not occur in the moving process, so that the automobile can not be parked in a parking space.
Further, in the first embodiment of the present invention, the hydraulic system for an automobile further includes:
a bottom plate 11 fixed on the oil tank 1 and used for rotatably connecting with the chassis of the automobile.
Here, the oil tank 1 is fixed to the bottom plate 11 by welding, and for the first hydraulic cylinder 2 and the second hydraulic cylinder 4, a support member is provided at the opposite positions of the bottom plate 11 to the first hydraulic cylinder 2 and the second hydraulic cylinder 4, respectively, by which the fixation of the first hydraulic cylinder 2 and the second hydraulic cylinder 4 is achieved.
By way of example of the fixation between the first hydraulic cylinder 2 and the base plate 11, the support member provided between the base plate 11 and the first hydraulic cylinder 2 may be connected to the base plate 11 and the second hydraulic cylinder 4 by welding, screwing or the like. Accordingly, the fixation between the second hydraulic cylinder 4 and the bottom plate 11 is the same as the fixation between the first hydraulic cylinder 2 and the bottom plate 11 described above.

When the vehicle is not required to be parked by adopting the automobile hydraulic system, the automobile hydraulic system is attached to the automobile chassis, namely the rotating arm is arranged in parallel with the automobile chassis; when the vehicle needs to be parked by adopting the vehicle hydraulic system, the rotating arm needs to be rotated to the position perpendicular to the chassis of the vehicle, so that the vehicle hydraulic system can be positioned in a workable space position. Here, the rotating arm is connected to a vehicle control unit of the motor vehicle.
The rotating arm is connected with a whole vehicle controller of the automobile, an angle sensor is arranged on the rotating arm and used for detecting the rotating angle of the rotating arm, and the angle sensor is connected with the whole vehicle controller of the automobile; a buzzer connected with the whole vehicle controller is also arranged in the driving process; the keyboard in the cab is also provided with a start button and a close button, the start button is used for sending a signal for controlling the rotating arm to rotate in the direction perpendicular to the chassis of the automobile to the whole automobile controller, and the close button is used for sending a signal for controlling the rotating arm to rotate in the direction parallel to the chassis of the automobile to the whole automobile controller.
When the driver presses the start key, the rotating arm starts to rotate towards the direction perpendicular to the automobile chassis, the whole vehicle controller determines the rotating position of the rotating arm according to the angle value fed back by the angle sensor, and when the whole vehicle controller determines that the rotating angle of the rotating arm reaches 90 degrees, the whole vehicle controller controls the buzzer to send out a first preset sound so as to prompt the driver that the rotating action of the rotating arm is finished; when the driver presses the closing button, the rotating arm moves towards the direction parallel to the automobile chassis, and when the whole automobile controller determines that the rotating angle of the rotating arm is 0 degrees, namely the rotating arm rotates to the position parallel to the automobile chassis, at the moment, the whole automobile controller controls the buzzer to send out a second preset sound so as to prompt the driver to finish rotating, and the driver can drive away.
It should be noted that the vehicle in the second embodiment of the present invention includes the entire contents of the hydraulic system of the vehicle in the first embodiment described above.
Referring to fig. 2, in a third embodiment of the present invention, there is provided a control method of an automotive hydraulic system, including:
and step 1, controlling the automobile hydraulic system to rotate to a position vertical to the automobile chassis.
And 2, controlling the first driving motor 9 to rotate towards a first direction, and acquiring a first oil level in the first hydraulic cylinder 2.
And 3, controlling the first driving motor 9 to rotate towards a second direction when the first oil level reaches a first preset level, and acquiring a second oil level in the second hydraulic cylinder 4.
And 4, when the second oil level reaches a second preset level, controlling the first driving motor 9 to stop rotating, and controlling the wheels 7 to roll towards a preset direction.
Before the steps in the embodiment of the invention are carried out, a driver is required to stop the automobile to a position parallel to the parking place, and the position requiring the automobile to stop can ensure that the automobile can be completely stopped in the parking place after being transversely moved, and no scratch is generated between the automobile and other vehicles.
The control method of the hydraulic system of the automobile according to the third embodiment of the present invention should be used after being mounted on the automobile. In step 1, the rotation of the hydraulic system of the automobile to the position perpendicular to the chassis of the automobile is controlled by the rotating arm arranged on the chassis of the automobile. The rotating arm is controlled to rotate to the position vertical to the chassis of the automobile.
In step 2, the first oil level in the first hydraulic cylinder 2 is obtained by a first displacement sensor provided in the first hydraulic cylinder 2, and the first displacement sensor is connected to the vehicle control unit. When the first oil level reaches a first preset level, the amount of oil sucked into the first hydraulic cylinder 2 is considered to be capable of meeting the oil amount requirement required for jacking up the automobile.
In step 3, the second oil level in the second hydraulic cylinder 4 is acquired by a second displacement sensor provided in the second hydraulic cylinder 4, and the second displacement sensor is connected to the vehicle control unit. When the wheels 7 of the hydraulic system of the car are in contact with the ground, the car has not yet been lifted up, and when the second oil level reaches a second preset level, it can be considered that the car has been lifted up by the hydraulic system of the car.
In order to enable the driver to know that the first oil level in the first hydraulic cylinder 2 reaches a first preset level and the second oil level in the second hydraulic cylinder 4 reaches a second preset level, the whole vehicle controller controls the buzzer to emit different third preset sounds and fourth preset sounds. After hearing the third preset sound, the driver executes the step 3; when the driver hears the fourth preset sound, step 4 is executed.
In step 4, the wheels 7 are controlled to roll in a preset direction, and the wheels 7 are controlled to roll by controlling the rotation of the second driving motor. Since the output shaft of the second drive motor rotates coaxially with the wheel 7, it is possible to realize rolling of the wheel 7 by rotation of the second drive motor.
Further, in a third embodiment of the present invention, the control method of the hydraulic system of an automobile further includes:
when the wheel 7 rolls to a preset position, the stop valve 51 is controlled to open.
Here, it is determined that the road vehicle has been correctly parked inside the parking space at the position where the wheel 7 rolls to the preset position, which is judged by the distance between the wheel 7 and the parking line sensed by the distance sensor provided on the wheel 7. At the same time, the driver can also consider to confirm whether the vehicle is parked in the parking space, and manually send a signal for opening the stop valve 51 to the whole vehicle controller through a button.
In the above steps, when the control stop valve 51 is opened, the vehicle is correctly parked in the parking space, and at this time, the hydraulic system of the vehicle needs to be restored to its original state. Thus, the shut-off valve 51 needs to be opened so that the oil in the second hydraulic cylinder 4 flows back into the oil tank 1, thereby allowing the vehicle to resume contact with the ground.
Further, in a third embodiment of the present invention, the control method of the hydraulic system of the automobile further includes:
the operating time of the opening of the shut-off valve 51 is obtained.
When the operating time reaches a first preset time, the stop valve 51 is controlled to be closed, and the hydraulic system of the automobile is controlled to rotate to a position parallel to the chassis of the automobile.
Since the amount of oil flowing into the second hydraulic cylinder 4 is the same each time, it is tested in advance how long the shutoff valve 51 is open at the time of design to allow the oil in the second hydraulic cylinder 4 to flow back into the oil tank 1. When the time for which the shut-off valve 51 is opened reaches the first preset time, it is considered that the oil in the second hydraulic cylinder 4 has completely flowed back into the oil tank 1, and at this time, the vehicle controller controls the shut-off valve 51 to be closed. And a fifth preset sound is sent out through the buzzer to remind the driver. After hearing the fifth preset sound, the driver presses the closing button, and the whole vehicle controller controls the rotating arm to rotate to a position parallel to the vehicle chassis.
The control method of the automobile hydraulic system provided by the third embodiment of the invention has the same technical effects as the automobile hydraulic system and the automobile. According to the control method of the automobile hydraulic system, the problem that normal parking cannot be performed due to the short parking space length when the automobile is parked laterally can be solved.
While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the present invention.
