Description

Technical Field

[0001] The present application relates to the field of hydraulic lifting and loading and unloading equipment, and in particular to a novel intelligent hydraulic tailgate. Background Art

[0002] The hydraulic tail lift is a hydraulic lifting and unloading device installed at the rear of a vehicle and powered by an onboard battery. When loading and unloading goods, the staff uses the hydraulic tail lift to operate the hydraulic tail lift to open, lower, lower, raise, lift and close the door.

[0003] In the related art, when a worker controls a hydraulic tailgate to perform an action, the worker first operates the corresponding button to start the hydraulic tailgate to move. Then, the worker continues to press the corresponding button to make the hydraulic tailgate continue to move until it rotates to another state. In this process, the worker needs to press the corresponding button while observing the state of the hydraulic tailgate. When the worker observes that the hydraulic tailgate rotates to another state, he stops pressing the corresponding button, thereby controlling the hydraulic tailgate to stop.

[0004] Since the staff needs to observe the status of the hydraulic tail lift in real time during the operation of the hydraulic tail lift, it is easy to cause a deviation between the status of the hydraulic tail lift and the ideal status. Summary of the invention

[0005] In order to more accurately control the hydraulic tailgate, the present application provides a new type of intelligent hydraulic tailgate.

[0006] The present application provides a novel intelligent hydraulic tailgate adopting the following technical solution:

Then start the lifting oil cylinder, the lifting oil cylinder drives the lifting rod to start rotating with the hinge position of the lifting rod and the connecting plate as the center of the circle, and the load-bearing platform remains horizontal and abuts against the ground, thereby completing the lifting operation of the load-bearing platform, and then pushes the goods onto the load-bearing platform. When the load-bearing platform transports goods, first perform the lifting operation, the lifting oil cylinder drives the load-bearing platform to remain horizontal and move upward until the end of the load-bearing platform close to the vehicle body abuts against the vehicle body, and the load-bearing platform and the bottom of the carriage are at the same horizontal plane.

[0045] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-3 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0046] The embodiment of the present application discloses a novel intelligent hydraulic tailgate, which is arranged at the rear of a vehicle body. Figure 1 and Figure 2The novel intelligent load-bearing platform 1 includes a load-bearing platform 1, a hydraulic device 2, a nine-axis gyroscope 3 and a control module 4. The nine-axis gyroscope 3 detects the posture of the hydraulic device 2, and the control module 4 can control the hydraulic device 2 to drive the load-bearing platform 1 to move more accurately.

[0047] Specifically, the hydraulic device 2 is arranged at one end of the load-bearing platform 1 close to the vehicle body, and is used to drive the load-bearing platform 1 to move. The hydraulic device 2 includes a lifting assembly 21 and a rotating plate assembly 22, and the lifting assembly 21 includes a connecting plate 211 fixedly connected to the rear of the vehicle body. Two lifting rods 212 are hinged near the two ends of the connecting plate 211, and the lifting rod 212 is hinged to the load-bearing platform 1 at one end away from the connecting plate 211. A lifting cylinder 213 is hinged at the connecting plate 211 at a position directly below each lifting rod 212, and the cylinder body of the lifting cylinder 213 is hinged to the side of the connecting plate 211 away from the vehicle body, and the piston rod of the lifting cylinder 213 is arranged in a direction away from the connecting plate 211, and the piston rod of the lifting cylinder 213 is hinged to the lifting rod 212 near the load-bearing platform 1. The turntable assembly 22 includes two turntable cylinders 221 hinged to the connecting plate 211. The cylinder bodies of the turntable cylinders 221 are hinged to the side of the connecting plate 211 away from the vehicle body. The two turntable cylinders 221 are respectively located at positions away from each other of the two lifting cylinders 213. The piston rods of the turntable cylinders 221 are set in a direction away from the connecting plate 211. The piston rods of the turntable cylinders 221 are hinged to the supporting platform 1.

[0048] When the user uses it, when the load-bearing platform 1 is set vertically and the compartment is closed, firstly, by retracting the turn plate oil cylinder 221, the load-bearing platform 1 can be rotated in the direction away from the vehicle body, and the load-bearing platform 1 rotates around the hinge position of the lifting rod 212 and the load-bearing platform 1 as the center of the circle; the load-bearing platform 1 is gradually rotated from the vertical state to the horizontal state, and the rotation operation of the load-bearing platform 1 is completed. Then, by retracting the lifting oil cylinder 213, the lifting rod 212 is driven to rotate around the hinge position of the lifting rod 212 and the connecting plate 211 as the center of the circle, and the load-bearing platform 1 maintains the horizontal state without changing, until the load-bearing platform 1 abuts against the ground, and the lifting operation of the load-bearing platform 1 is completed, and the goods are pushed onto the load-bearing platform 1. When the load-bearing platform 1 is folded, the lifting operation is first performed to make the load-bearing platform 1 move upward, until the end of the load-bearing platform 1 close to the vehicle body abuts against the vehicle body, and then the goods are pushed. After the goods move into the compartment, the rotation operation is performed until the load-bearing platform 1 is in a vertical state and abuts against the vehicle body.

[0049] Reference Figure 1 and Figure 3It can be understood that the hydraulic device 2 is used to receive different control instructions to drive the load-bearing platform 1 to perform opening, lowering, lowering, raising, lifting and closing actions. Specifically, the new intelligent load-bearing platform 1 in the embodiment of the present application includes a control device 5. The control device 5 is connected to the hydraulic device 2 and is used to output different instructions. Among them, the control device 5 includes three types: a remote controller 5, a wire controller 52 and an operating box 53, so that the staff can perform short-range and long-range control of the hydraulic device 2, so that the staff can control the hydraulic device 2.

[0050] Reference Figure 1 and Figure 2 The nine-axis gyroscope 3 is used to detect the acceleration generated when the carrying platform 1 performs a descending action or a lowering action, and output an acceleration signal. It is also used to collect in real time the rotation angle formed between the carrying platform 1 and the hydraulic device 2 when the carrying platform 1 performs an opening action, a raising action, and a lifting action, and output an angle detection signal.

[0051] It is worth noting that when the carrying platform 1 performs the descending action, the head-down action and the door-closing action, the air resistance or other factors may produce a certain reverse acceleration during the rotation of the carrying platform 1. When the reverse acceleration is not zero, it is considered that the carrying platform 1 touches the ground or the car.

[0052] Specifically, the nine-axis gyroscope 3 includes a three-axis accelerometer and a three-axis gyroscope. The three-axis accelerometer is used to detect the acceleration generated by the load-bearing platform 1 when performing a descending action, a head-down action, and a door-closing action, and output an acceleration detection signal. The three-axis gyroscope is used to collect in real time the rotation angle formed between the load-bearing platform 1 and the hydraulic device 2 when the load-bearing platform 1 performs an opening action, a head-up action, and a lifting action, and output an angle detection signal.

[0053] When collecting the rotation angle formed between the carrying platform 1 and the hydraulic device 2, the rotation angle formed between the carrying platform 1 and the hydraulic device 2 can be directly collected, or the rotation angles of both the carrying platform 1 and the hydraulic device 2 can be collected simultaneously. Using the nine-axis gyroscope 3 to collect the angle is a mature technology in the relevant field, so it will not be described in detail here.

[0054] It should be noted that if the method of directly collecting the rotation angle formed between the carrying platform 1 and the hydraulic device 2 is adopted, a collection direction of the rotation angle needs to be specified to avoid the same rotation angle causing the carrying platform 1 to present different postures. In an example, it is assumed that the connection point between the carrying platform 1 and the hydraulic device 2 is used as the origin to establish an xy coordinate system. When the carrying platform 1 completes the opening action, according to the order of the coordinate system quadrants, the rotation angle formed between the carrying platform 1 and the hydraulic device 2 should be 210°, and the obtuse angle formed between the carrying platform 1 and the hydraulic device 2 is 150°. When the carrying platform 1 performs the head-up action, according to the order of the coordinate system quadrants, the rotation angle formed between the carrying platform 1 and the hydraulic device 2 should be 150°. Therefore, when the method of directly collecting the rotation angle formed between the carrying platform 1 and the hydraulic device 2 is adopted, a collection direction of the rotation angle needs to be specified.

[0055] The control module 4 is connected to the nine-axis gyroscope 3, and is used to receive an acceleration detection signal, and to output a first stop signal when the reverse acceleration reflected by the acceleration detection signal is not zero, and is also used to receive an angle detection signal, and to output a second stop signal when the rotation angle reflected by the received angle detection signal is within a corresponding preset angle range.

[0056] The control module 4 includes a data interface 41 , a preset unit 42 , a processing unit 43 , a confirmation unit 44 and a control unit 45 .

[0057] The data interface 41 is connected to the nine-axis gyroscope 3 and is used to receive and transmit acceleration detection signals and angle detection signals.

[0058] The preset unit 42 is used to set and output a time threshold and a preset angle range under different postures.

[0059] The processing unit 43 is connected to the data interface 41, and is used to output a trigger signal when the reverse acceleration reflected by the acceleration detection signal is not zero. Otherwise, no trigger signal is output.

[0060] The confirmation unit 44 is connected to the processing unit 43, and is used to receive a trigger signal, calculate the duration of the trigger signal, and output a time signal.

[0061] On the one hand, the control unit 45 is respectively connected to the preset unit 42 and the confirmation unit 44, and is used to output a first stop signal when the duration reflected by the time signal exceeds the time threshold. It is worth noting that the supporting platform 1 may touch some obstacles when rotating, resulting in a reverse acceleration greater than the reverse acceleration. At this time, the reverse acceleration is not zero and does not mean that the supporting platform 1 has reached the desired state. The supporting platform 1 may touch some obstacles when rotating, resulting in a reverse acceleration. At this time, the reverse acceleration generated does not mean that the supporting platform 1 has reached the desired state. Therefore, by calculating the duration of the reverse acceleration that is not zero and comparing it with the time threshold, the current state of the supporting platform 1 can be confirmed again to avoid the situation where some supporting platforms 1 stop without moving to the target position.

[0062] On the other hand, the control unit 45 is also connected to the data interface 41, and is used to output a second stop signal when the rotation angle reflected by the received angle detection signal is within the corresponding preset angle range.

[0063] Specifically, the control unit 45 can not only control the load-bearing platform 1 to move to the target position, but also detect the change in the rotation angle formed between the load-bearing platform 1 and the hydraulic device 2 through the nine-axis gyroscope 3 when the posture of the load-bearing platform 1 changes after the cargo is placed on the load-bearing platform 1, and adjust and restore the angle change of the load-bearing platform 1 caused by the weight of the cargo to avoid the change in the posture of the load-bearing platform 1 caused by the weight of the cargo.

[0064] In one embodiment, it is assumed that the load-bearing platform 1 is 0° and the hydraulic device 2 is 45° when the door is open; the load-bearing platform 1 is 90° and the hydraulic device 2 is 45° when the door is closed; the load-bearing platform 1 is 0° and the hydraulic device 2 is -45° when the head is raised; the load-bearing platform 1 is -5° and the hydraulic device 2 is -45° when the head is lowered; the hydraulic plate is 0° and the hydraulic device 2 is 45° when the lifting posture is in progress; the load-bearing platform 1 is 0° and the hydraulic device 2 is -45° when the hydraulic plate is in the descending posture. During the rotation of the load-bearing platform 1, the nine-axis gyroscope 3 collects the rotation angles of the load-bearing platform 1 and the hydraulic device 2 in real time, and the control unit 45 determines the current posture of the load-bearing platform 1 according to the current rotation angles of the load-bearing platform 1 and the hydraulic device 2, and compares the current rotation angles of the load-bearing platform 1 and the hydraulic device 2 with the angle value corresponding to the current posture of the load-bearing platform 1, and determines whether the current posture of the load-bearing platform 1 is within the preset angle range. If so, the load-bearing platform 1 is adjusted to the angle corresponding to the current posture.

[0065] The hydraulic device 2 is connected to the control unit 45 and is used to stop driving the carrying platform 1 to move when receiving the first stop signal or the second stop signal.

[0066] Considering that when the load-bearing platform 1 is rotating, if a worker approaches the load-bearing platform 1 , the load-bearing platform 1 may bump into the worker, causing danger. Therefore, the novel intelligent hydraulic tailgate of the embodiment of the present application further includes a proximity detection device 6 and an audible and visual alarm device 7 .

[0067] The proximity detection device 6 is used to detect whether a person approaches the carrying platform 1 , and output a proximity signal when a person approaches the carrying platform 1 .

[0068] The control unit 45 is connected to the proximity detection device 6 and is used to output an alarm signal when receiving a proximity signal.

[0069] The sound and light alarm device 7 is connected to the control unit 45 and is used to sound an alarm when receiving an alarm signal. Preferably, the sound and light alarm device 7 is a buzzer.

[0070] The implementation principle of a new type of intelligent hydraulic tailgate in the embodiment of the present application is as follows: by setting a nine-axis gyroscope 3, it is possible to detect the acceleration generated by the carrying platform 1 when performing a descending action, a lowering action and a closing action, and it is also possible to collect in real time the rotation angle formed between the carrying platform 1 and the hydraulic device 2 when the carrying platform 1 performs an opening action, a raising action and a lifting action, so that the control module 4 can control the hydraulic device 2 to stop driving the carrying platform 1 to move when the reverse acceleration generated by the carrying platform 1 is not zero, and at the same time, it can control the hydraulic device 2 to stop driving the carrying platform 1 to move when the rotation angle formed between the carrying platform 1 and the hydraulic device 2 is within the corresponding angle preset range, so that the carrying platform 1 automatically stops after moving to the target position, so as to achieve more precise control of the carrying platform 1.

[0071] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Any feature disclosed in this specification (including the abstract and drawings), unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
