[0004] The technical scheme needs electromagnet to be continuously powered to realize traction work in the process of traction, energy consumption is higher, and the shape of U-shaped connecting groove leads to that towing device body is easy to collide with U-shaped connecting groove when following vehicle body turns. UTILITY MODEL CONTENTS

[0005] Therefore, the utility model aims at providing a high stability unmanned tractor to solve the technical problems mentioned in the background.

[0006] To achieve the above object, the utility model provides the following technical scheme: a high stability unmanned tractor, including tractor main body, hanging seat and cargo compartment, the inside of hanging seat is connected with limiting plate through torsion spring shaft, the top of limiting plate is equipped with limiting hole, and the inside of limiting hole is provided with bolt, the inside of hanging seat is installed with first electromagnet and second electromagnet on top.

[0007] When the towing vehicle body reverses to displace the hanger seat to the hanger position, the hanger abuts against the limiting plate, the limiting plate rotates into the hanger seat, the hanger is covered by the rotation of the two limiting plates, and the bolt corresponds to the limiting hole, at this time, the bolt falls into the limiting hole under the influence of gravity, thereby avoiding the phenomenon that the hanger is separated from the hanger seat due to the reverse rotation of the limiting plate driven by the torsion spring shaft; when it is needed to end the mounting, the first electromagnet and the second electromagnet are simultaneously started to generate magnetic attraction, the first electromagnet is large at the top and small at the bottom, the magnetism at the top of the first electromagnet is larger than that at the bottom of the first electromagnet, and the magnetism gradually increases, the first electromagnet at the top has the maximum magnetism in cooperation with the second electromagnet, thereby the bolt moves upward and separates from the limiting hole under the influence of magnetism, at this time, the limiting plate is reversely rotated by the torsion spring shaft, thereby the hanger is separated from the hanger seat, and the first electromagnet and the second electromagnet can be closed to make the bolt slide to the top of the limiting plate.

[0008] Further, one side of the limiting plate is in a circular arc shape, and the limiting plate is rotationally connected with the hanger seat through the torsion spring shaft.

[0009] By adopting the above technical scheme, the hanger abuts against the limiting plate, the limiting plate rotates into the hanger seat, and the hanger is covered by the rotation of the two limiting plates.

[0010] Further, the limiting plate is provided with two, and the two limiting plates are mirror image arranged.

[0011] By adopting the above technical scheme, the outer surface and the back of the hanger are covered by the two limiting plates, and the limiting plate is clamped by the bolt, thereby avoiding the phenomenon that the hanger is separated from the hanger seat.

[0012] Further, the bolt is made of iron material, and the width of the bottom of the first electromagnet is smaller than the width of the top of the first electromagnet.

[0013] By adopting the above technical scheme, the first electromagnet is large at the top and small at the bottom, the magnetism at the top of the first electromagnet is larger than that at the bottom of the first electromagnet, and the magnetism gradually increases, the first electromagnet at the top has the maximum magnetism in cooperation with the second electromagnet, thereby the bolt moves upward and separates from the limiting hole under the influence of magnetism.

[0014] Further, the bolt is detachably connected with the limiting hole, and the bolt is slidably connected with the hanger seat.

[0015] By adopting the above technical scheme, the first electromagnet and the second electromagnet are simultaneously started to generate magnetic attraction, thereby the bolt moves upward and separates from the limiting hole under the influence of magnetism.

[0016] Further, the towing vehicle body is provided with a signal transceiving antenna at the top, and is provided with a control panel at one side.

[0017] By adopting the above technical solution, staff can remotely control the movement of the tractor body through the signal transceiver antenna, or achieve unmanned driving through the tractor body's own program. Staff can view various parameters of the tractor body and set programs through the control panel.

[0018] Furthermore, the cargo box is located on the right side of the tractor body, and a hanging device is fixed on the side of the cargo box closest to the tractor body.

[0019] By adopting the above technical solution, when it is necessary to transport goods, the main body of the tractor moves to the side of the cargo box and reverses, so that the trailer moves toward the hanger to complete the loading work.

[0020] Furthermore, the hanging piece abuts against the limiting plate.

[0021] By adopting the above technical solution, the main body of the tractor moves to the side of the cargo box and reverses, causing the trailer to move toward the hanger. Then the hanger abuts against the limiting plate, causing the limiting plate to rotate inward toward the trailer.

[0022] Furthermore, four dampers are installed between the tractor body and the trailer, and each of the four dampers is fitted with a spring.

[0023] By adopting the above technical solution, the kinetic energy generated when the hanger comes into contact with the hanger will cause the damper and spring to contract, thereby absorbing the kinetic energy through the damper to reduce damage. When the hanger is towed on the road, it can also absorb energy through the damper, and the spring drives the damper to reset so that it can absorb energy again next time.

[0024] In summary, the present invention has the following main advantages:

[0025] This invention, through the arrangement of a limiting plate, a limiting hole, a pin, a first electromagnet, and a second electromagnet, ensures that when the tractor body reverses, causing the mount to move towards the hanger, the hanger abuts against the limiting plate, causing the limiting plate to rotate inwards. As the two limiting plates rotate, they enclose the hanger, and the pin aligns with the limiting hole. At this time, the pin falls into the limiting hole under the influence of gravity, thus preventing the hanger from detaching from the mount due to the torsion spring shaft driving the limiting plate to reverse. When it is necessary to disengage the hanger, the first and second electromagnets activate simultaneously to generate magnetic attraction, causing the first electromagnet to move upwards and downwards. The small shape makes the magnetism at the top of the first electromagnet stronger than that at the bottom, and the magnetism gradually increases. Combined with the second electromagnet, this maximizes the magnetism at the top of the first electromagnet, causing the pin to move upwards under magnetic influence and separate from the limiting hole. At this point, the torsion spring shaft drives the limiting plate to reverse, thus separating the hanger from the mounting base. Simultaneously, the first and second electromagnets are closed, allowing the pin to slide down to the top of the limiting plate. The mechanical structure features automatic locking, high connection stability, and low energy consumption as it does not require continuous power. Furthermore, its compact structure does not affect the rotation of the hanger and offers good flexibility. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1:

[0036] A highly stable unmanned tractor, such as Figures 2-6As shown, the vehicle includes a tractor body 1, a mounting bracket 8, and a cargo box 2. A limiting plate 10 is connected to the inside of the mounting bracket 8 via a torsion spring shaft 9. One side of the limiting plate 10 is arc-shaped. The limiting plate 10 is rotatably connected to the mounting bracket 8 via the torsion spring shaft 9. Two limiting plates 10 are provided, mirror-shaped. A limiting hole 11 is formed at the top of each limiting plate 10, and a pin 12 is installed inside the limiting hole 11. The pin 12 is detachably connected to the limiting hole 11 and slidably connected to the mounting bracket 8. When transporting goods, the tractor body 1 moves to the side of the cargo box 2 and reverses, causing the mounting bracket 8 to move towards the hanging member 5. The hanging member 5 then abuts against the limiting plate 10, causing the limiting plate 10 to rotate inwards into the mounting bracket 8. As the two limiting plates 10 rotate, they enclose the hanging member 5, and the pin 12 aligns with the limiting hole 11. At this time, the pin 12 falls into the limiting hole 11 under the influence of gravity, thus preventing the torsion spring shaft 9 from driving the limiting plate 10. The reversal causes the hanging piece 5 to detach from the hanging base 8. A first electromagnet 13 and a second electromagnet 14 are installed inside the upper part of the hanging base 8. The pin 12 is made of iron. The width of the bottom of the first electromagnet 13 is smaller than the width of its top. When the hanging needs to be terminated, the first electromagnet 13 and the second electromagnet 14 are activated simultaneously to generate magnetic attraction. The shape of the first electromagnet 13, which is larger at the top and smaller at the bottom, makes the magnetism at the top of the first electromagnet 13 stronger than that at the bottom, and the magnetism gradually increases. Combined with the second electromagnet 14, this maximizes the magnetism at the top of the first electromagnet 13, causing the pin 12 to move upwards under magnetic influence and separate from the limiting hole 11. At this time, the torsion spring shaft 9 drives the limiting plate 10 to reverse, thus separating the hanging piece 5 from the hanging base 8. Simultaneously, the first electromagnet 13 and the second electromagnet 14 are closed, causing the pin 12 to slide down to the top side of the limiting plate 10.

[0037] See Figure 1 In the above embodiment, a signal transceiver antenna 3 is installed on the top of the tractor body 1, and a control panel 4 is installed on one side of the tractor body 1. The cargo box 2 is located on the right side of the tractor body 1, and a hanger 5 is fixed on the side of the cargo box 2 near the tractor body 1. The hanger 5 abuts against the limiting plate 10. The tractor body 1 can be remotely controlled to move through the signal transceiver antenna 3, or it can be driven unmanned through the tractor body 1's own program. The staff can view various parameters of the tractor body 1 and set programs through the control panel 4. When it is necessary to transport goods, the tractor body 1 moves to the side of the cargo box 2 and reverses, so that the hanger 8 moves toward the hanger 5 to complete the loading.

[0038] Example 2:

[0039] Based on the above embodiment one, the following settings are now implemented to reduce collision damage.

[0040] See Figure 1 and Figure 2In the above embodiment, four dampers 6 are installed between the tractor body 1 and the mount 8. Each of the four dampers 6 is fitted with a spring 7. The kinetic energy generated when the mount 5 contacts the mount 8 will cause the dampers 6 and springs 7 to contract, thereby absorbing the kinetic energy through the dampers 6 to reduce damage. When the vehicle is towing on the road, it can also absorb energy through the dampers 6 and reset through the springs 7 so that it can absorb energy again next time.

[0041] The implementation principle of this utility model is as follows: First, the staff can remotely control the movement of the tractor body 1 through the signal transceiver antenna 3, or achieve unmanned driving through the program of the tractor body 1 itself. The staff can view various parameters of the tractor body 1 and set the program through the control panel 4.

[0042] When goods need to be transported, the tractor body 1 moves to the side of the cargo box 2 and reverses, causing the hanger 8 to move toward the hanger 5. Then the hanger 5 abuts against the limiting plate 10, causing the limiting plate 10 to rotate inward toward the hanger 8. As the two limiting plates 10 rotate, they cover the hanger 5, and the pin 12 corresponds to the limiting hole 11. At this time, the pin 12 falls into the limiting hole 11 under the influence of gravity, thereby preventing the phenomenon of the hanger 5 and the hanger 8 falling off due to the torsion spring shaft 9 driving the limiting plate 10 to reverse.

[0043] At the same time, the kinetic energy generated by the contact between the hanger 5 and the hanger 8 will cause the damper 6 and the spring 7 to contract, thereby absorbing the kinetic energy through the damper 6 to reduce damage. When it is towed on the road afterward, it can also absorb energy through the damper 6, and the spring 7 will drive the damper 6 to reset so that it can absorb energy again next time.

[0044] When the mounting needs to be terminated, the first electromagnet 13 and the second electromagnet 14 are activated simultaneously to generate magnetic attraction. The shape of the first electromagnet 13, which is larger at the top and smaller at the bottom, makes the magnetism at the top of the first electromagnet 13 stronger than that at the bottom, and the magnetism gradually increases. This, together with the second electromagnet 14, makes the magnetism at the top of the first electromagnet 13 the strongest, thereby causing the pin 12 to move upward under the influence of the magnetism and separate from the limiting hole 11. At this time, the limiting plate 10 is driven to reverse through the torsion spring shaft 9, thereby separating the hanger 5 from the hanger 8. At the same time, the first electromagnet 13 and the second electromagnet 14 can be closed, causing the pin 12 to slide down to the top side of the limiting plate 10.
