[0053] Unless otherwise stated, the term "plurality" means two or more.

[0054] Because existing cab lifts mostly use manual or semi-automatic methods to raise or lower the cab, lacking intelligent and automated functions, the operation of these lifts is difficult and complex. Even the slightest operator negligence can cause safety accidents, resulting in damage to personnel and vehicles. Therefore, existing lifts have some technical problems in terms of efficiency and convenience.

[0055] To solve the above problems, the application provides a lifting device applied to a cab and a vehicle, which comprises a lifting remote controller 100, a lifting driving device 200 and a lifting oil cylinder 300; the lifting remote controller 100 is connected with the lifting driving device 200, the lifting driving device 200 is connected with the lifting oil cylinder 300; the lifting remote controller 100 is used for sending a first trigger signal to the lifting driving device 200 to drive the lifting driving device 200 to drive the lifting oil cylinder to lift, so that the cab is lifted; the lifting remote controller 100 is also used for sending a second trigger signal to the lifting driving device 200 to drive the lifting driving device 200 to drive the lifting oil cylinder to fall back, so that the cab falls back. Through the lifting remote controller 100, the operator can be in a safe position away from the cab of the vehicle, and the lifting height and the falling back operation of the cab can be accurately controlled according to the lifting remote controller 100, so that the safety and the convenience of the operation are improved.

[0056] The technical solutions of the application and how the technical solutions solve the above technical problems will be described in detail in specific embodiments. The specific embodiments below can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the application will be described below with reference to the drawings.

[0057] Figure 1 A structure diagram of a lifting device applied to a cab is provided in the embodiments of the application; as shown in Figure 1 The lifting device applied to the cab provided by the embodiments comprises a lifting remote controller 100, a lifting driving device 2 and a lifting oil cylinder 3; the lifting remote controller 100 is connected with the lifting driving device 200, the lifting driving device 200 is connected with the lifting oil cylinder 300; the lifting remote controller 100 is used for sending a first trigger signal to the lifting driving device 200 to drive the lifting driving device 200 to drive the lifting oil cylinder 300 to lift, so that the cab is lifted; the lifting remote controller 100 is also used for sending a second trigger signal to the lifting driving device 200 to drive the lifting driving device 200 to drive the lifting oil cylinder 300 to fall back, so that the cab falls back.

[0058] Exemplarily, the lifting remote controller 100 is a control device connected with the lifting driving device 200 through the wire harness 400, and different buttons are arranged on the remote controller for generating different trigger signals. The remote controller has two different signal outputs, i.e., a first trigger signal and a second trigger signal, which are respectively used for controlling the lifting and falling operations; the lifting driving device 200 is a device for receiving the signal of the remote controller and converting it into an electric action. When receiving the signal from the remote controller, the driving device analyzes the signal content and drives the connected lifting oil cylinder 300. In the cab lifting system, one end of the lifting oil cylinder is fixed on the vehicle chassis, and the other end is connected to the bottom of the cab. When the oil cylinder is elongated, the cab is pushed up; when the oil cylinder is shortened, the cab is lowered.

[0059] In the embodiment, the first trigger signal is sent to the lifting driving device 200 through the lifting remote controller 100, the lifting driving device 200 receives the signal and drives the lifting oil cylinder 300 to lift, so that the cab is lifted; the piston rod of the lifting oil cylinder 300 is extended to push the cab to gradually rise to a predetermined height or position. This operation is usually used to provide more space when maintaining, cleaning or inspecting the bottom of the vehicle. The second trigger signal is sent to the lifting driving device 200 through the lifting remote controller 100, the lifting driving device 200 receives the signal and drives the lifting oil cylinder 300 to fall, so that the cab is lowered; the piston rod of the lifting oil cylinder 300 is retracted to gradually lower the cab until it returns to its original position. This operation ensures that the cab can be safely and stably reset after completing the task. Thus, the lifting remote controller is used, the operator can be in a safe area away from the cab of the vehicle, and the lifting height of the cab and the falling action can be flexibly adjusted by accurately operating the control instructions on the remote controller. The safety of the operation process is improved, the convenience of the operation is increased, and the whole operation process is more efficient and smooth.

[0060] Please refer to Figures 2 to 6 . Figure 2 Another application of the lifting device for the cab is provided in the embodiment of the application. In Figure 1 the embodiment, the first oil pipe 500 and the second oil pipe 600 are connected between the lifting driving device 200 and the lifting oil cylinder 300; and the third oil pipe 700 is arranged in the lifting oil cylinder.

[0061] In one example, in Figure 2 the embodiment, as Figure 3As shown, the lifting remote control 100 provided in this embodiment is provided with a lift button 101 and a return button 102 on its first side; and a start button 103 on its second side. In response to a user simultaneously triggering the lift button 101 and the start button 103, the lifting remote control 100 generates a first trigger signal; and in response to a user simultaneously triggering the return button 102 and the start button 103, the lifting remote control 100 generates a second trigger signal. By simultaneously triggering specific button combinations on the lifting remote control 100: the lift button and the start button, and the return button and the start button, precise control of the lifting or return action is achieved. This design simplifies the operation process, improves operational efficiency and accuracy, and allows users to conveniently send specific trigger signals via the remote control to control the device's lifting or return action, enhancing operational convenience and safety.

[0062] In one example, the lift remote control is equipped with a warning light 104. The lift remote control 100 is also configured to illuminate the warning light 104 in response to the user individually triggering the lift button 101 or the lower button 102. This design provides users with immediate visual feedback, allowing them to intuitively confirm that their operation has been received and is being executed by the remote control. This instant feedback mechanism not only enhances the user experience, but also improves operational reliability and safety, reducing the risk of misoperation.

[0063] Combine Figure 2 、 Figure 4 、 Figure 5 and Figure 6 The lifting drive device 200 is provided with a controller 201, a first electromagnet 202, a second electromagnet 203, a lifting motor 204, and a lifting oil pump 205; wherein the controller 201 is connected to the lifting motor 204, the first electromagnet 202 and the second electromagnet 203, and the lifting motor 204 is connected to the lifting oil pump 205; the lifting remote control 100 is connected to the controller 201; the lifting drive device 200 is also provided with a solenoid valve 208 and a solenoid valve in-position sensor 209; the solenoid valve in-position sensor 209 is used to generate an in-position signal of the solenoid valve 208; and the lifting cylinder 300 is provided with a hydraulically controlled one-way valve 301.

[0064] In one example, the controller 201 is used to receive the first trigger signal sent by the lifting remote control 100. According to the first trigger signal, the first electromagnet 202 is energized to attract the solenoid valve 208 to move to the left, so that the right position of the solenoid valve 208 is connected. The pressure sensor of the left position of the solenoid valve 208 is pressurized and sends a signal to the controller 201. The controller 201 receives the solenoid valve in place signal and drives the lifting motor 204 to rotate, thereby driving the lifting oil pump 205 to pump oil, so that the piston of the lifting cylinder moves upward and the cab is lifted. The oil circuit when the piston of the lifting cylinder 300 moves upward is as follows: Figure 6The lifting is driven only when the lifting button 101 and the starting button 103 are pressed simultaneously in the lifting remote controller 100, because when only the starting button 103 is pressed, the lifting button 101 is not pressed, the right position of the electromagnetic valve 208 is not turned on, the controller 201 does not get the position signal of the electromagnetic valve 208, and the lifting motor 204 will not be driven to rotate, so as to prevent the pipe from being burst due to the excessive oil pressure in the pipeline; when only the lifting button 101 is pressed, the starting button 103 is not pressed, and the controller 201 does not get the driving signal of the lifting motor 204, so the lifting motor 204 does not rotate. If the lifting is to be stopped, any one or all of the lifting button 101 and the starting button 103 is released, if the lifting button 101 is released, the first electromagnet 202 is powered off, the electromagnetic valve 208 returns to the middle position under the action of the spring, the controller 201 does not detect the position signal of the electromagnetic valve 208, and the lifting motor 204 stops rotating; if the starting button 103 is released, the lifting motor 204 stops rotating.

[0065] In one example, the controller is configured to receive the second trigger signal sent by the lifting remote controller 100, control the second electromagnet 203 to be powered to attract the electromagnetic valve 208 to move to the right to make the left position of the electromagnetic valve be connected, and drive the lifting motor 204 to rotate to drive the lifting oil pump 205 to pump oil, at this time the hydraulic control check valve 301 controls the oil path to be a high-pressure oil path, the hydraulic control check valve 301 is reversely turned on, the piston of the lifting oil cylinder 300 moves downward, and the cab falls back. The oil path when the piston of the lifting oil cylinder 300 moves downward is as shown in FIG. 6. Figure 6The lift can only be driven to fall when both the return button 102 and the start button 103 are pressed simultaneously on the lift remote controller 100. This is because when only the start button 103 is pressed, the return button 102 is not pressed, the solenoid valve 208 is not conducting in the left position, and the controller 201 does not receive the solenoid valve 208 in-position signal, and thus does not drive the lift motor 204 to rotate, thereby preventing excessive oil pressure in the pipeline from causing a pipe burst. When only the return button 102 is pressed, the start button 103 is not pressed, and the controller 201 does not receive the drive signal for the lift motor 204, and the lift motor 204 does not rotate. To stop the fall, release any one or all of the fall button 102 or the start button 103. If the fall button 102 is released, the second electromagnet 203 is de-energized, and the solenoid valve 208 returns to the middle position under the action of the spring. The controller 201 does not detect the solenoid valve 208 arrival signal and thus controls the lifting motor 204 to stop rotating. If the start button 103 is released, the lifting motor 204 stops rotating. The present application confirms whether the lifting motor is allowed to start by detecting the state of the solenoid valve 208. If only the start button 103 is pressed without pressing the lift button 101 or the fall button 102, the solenoid valve 208 is not conductive and the controller will not start the lifting motor 204, thereby avoiding the problem of pipe burst caused by excessive oil pressure in the pipeline. During the lifting or falling process, releasing any button can stop the lifting or falling. This design improves the flexibility of operation and allows users to interrupt the lifting or falling action at any time as needed.

[0066] In one example, the controller 201 includes a processor and a motor driver. The processor is connected to the motor driver, the first electromagnet 202, and the second electromagnet 203. The processor is connected to the lift remote control 100, and the motor driver is connected to the lift motor 204. The processor is configured to receive a first trigger signal from the lift remote control 100 and, based on the first trigger signal, send a first control signal to the first electromagnet 202 and the motor driver. The first control signal is configured to control the first electromagnet 202 to attract the solenoid valve to move leftward and drive the motor driver to rotate the lift motor 204. The processor is also configured to receive a second trigger signal from the lift remote control 100 and, based on the second trigger signal, send a second control signal to the second electromagnet 203 and the motor driver. The second control signal is configured to control the second electromagnet 203 to attract the solenoid valve 208 to move rightward and drive the motor driver to rotate the lift motor 204. The controller 201 in this application integrates a processor and a motor driver, capable of processing signals from the lift remote control 100 and directly controlling the motor driver and electromagnets, simplifying the overall system architecture and improving control integration and efficiency.

[0067] In an example, Figure 5As shown, the lifting drive device 200 also includes a manual reversing handle 206, which is used to control the left and right positions of the solenoid valve when the lifting remote control 100 fails, and the manual lifting knob 207 is used to raise or lower the cab. The manual reversing handle 206 and the manual lifting knob 207 are provided in this application to cope with possible failures of the lifting remote control 100. When the remote control fails to work properly or the signal is interrupted for some reason, the operator can quickly switch to manual mode, use the manual reversing handle 206 to control the left and right positions of the solenoid valve, and use the manual lifting knob 207 to raise or lower the cab. This emergency operation capability ensures the reliability and continuity of the lifting system and avoids operation interruptions or safety hazards caused by remote control failures.

[0068] like Figure 4 The following figure shows a circuit diagram of a lifting device for a cab, provided in this embodiment. A lift remote controller 100 is connected to a control circuit, which is equipped with a first fuse 800 and a lift power switch 900. The first fuse 800 is connected to the lift power switch 900, which in turn is connected to the lift remote controller 100. In the circuit system, the lift remote controller 100 serves as the initiator of control signals and is connected to the entire control circuit. The control circuit is responsible for receiving signals from the lift remote controller 100 and controlling the operating states of subsequent electrical components accordingly. The first fuse 800 is a key safety protection element in the control circuit, primarily preventing overcurrent and protecting other components. It is typically connected in series in the circuit, ensuring that current must pass through the fuse. Furthermore, the first fuse 800 is connected to the lift power switch 900. The lift power switch 900 is a control switch used to manually control the on / off state of the circuit. To initiate a lift or lowering operation, the operator manually turns lift power switch 900 to the "on" position, allowing current to flow through the switch and to subsequent circuit components. Lift power switch 900 is then connected to lift remote control 100. When lift remote control 100 issues a control signal, the signal, while lift power switch 900 is on, transmits a trigger signal to subsequent parts of the control circuit, enabling control of the cab's lift or lowering.

[0069] In one example, a relay 1000 is provided in the control circuit; a first end of relay 1000 is connected to the lift power switch 900 and the lift remote control 100, a second end of relay 1000 is connected to the positive power line of the lift motor 204 of the lift drive device 200, and a third end of relay 1000 is the negative power line of relay 1000. As a key component in electrical control, relay 1000 can control the high current or voltage used by the motor by controlling the low current through the lift power switch 900. When the first end of relay 1000 is energized, the second end of relay 1000 closes, thereby connecting the positive power line of the lift motor, powering the motor and driving it; the third end of relay 1000 is the negative power line of relay 1000.

[0070] In one example, a second fuse 1100 is provided in the control circuit; it is connected to the positive power line of the lift motor 204 of the lift drive device 200. Second fuse 1100 is specifically included in the control circuit to enhance circuit safety and reliability. Second fuse 1100 primarily functions as an overcurrent protection element. When an abnormally high current flows through the circuit, it automatically blows, thereby shutting off the circuit and preventing damage to other components in the circuit, particularly the lift motor 204. Specifically, second fuse 1100 is directly connected to the positive power line of the lift motor 204 of the lift drive device 200. This means that the positive power line must pass through second fuse 1100 before supplying power to the lift motor 204. This design ensures that if the current increases abnormally during motor operation due to any reason, including but not limited to motor stall or excessive load, the second fuse 1100 will respond quickly, shutting off the current and protecting the motor and circuit from damage.

[0071] In this embodiment, the lifting remote control 100 is configured to trigger the first trigger signal to lift the cab only when the lifting button 101 and the start button 103 are pressed at the same time, and the lifting remote control 100 is configured to trigger the second trigger signal to lower the cab only when the return button 102 and the start button 103 are pressed at the same time. This double verification mechanism effectively prevents misoperation and improves the safety of the system; at the same time, the state of the solenoid valve 208 is detected to confirm whether the lifting motor 204 is allowed to start. If only the start button 103 is pressed but the lifting button 101 or the return button 102 is not pressed, the solenoid valve 208 is not connected, and the controller 201 does not receive the solenoid valve in place signal, and will not start the lifting motor to drive the oil pump to work, thereby avoiding the pipe burst problem caused by excessive oil pressure in the pipeline. The lift drive unit 200 also includes a manual reversing handle 206 and a manual lift knob 207. If the remote control fails to operate properly or the signal is interrupted, the operator can quickly switch to manual mode and directly control the raising or lowering of the cab using the manual reversing handle 206 and manual lift knob 207. This configuration ensures the reliability and continuity of the lift system, avoiding operational interruptions or safety hazards caused by remote control failures.

[0072] This embodiment provides a vehicle, on which is provided the lifting device applied to the cab provided in the above embodiment.

[0073] Finally, it should be noted that those skilled in the art will readily conceive of other embodiments of the present invention after considering the specification and practicing the invention disclosed herein. This invention is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein.
