Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but only represents the selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0023] Please refer to Figure 1 , which is a structural diagram of the trailer group 101 provided by the present invention. The docking mechanism 100 of the trailer group provided by the present invention is applied to the trailer group 101 with a transportation function. The trailer group 101 includes a main vehicle group 102 and a follow-up vehicle group 103. The docking mechanism 100 is used to connect the main vehicle group 102 and the follow-up vehicle group 103.

[0024] Please refer to Figures 2 to 5 , the docking mechanism 100 includes a camera 10, a slideway 20, a control chip 30, a first driving member 40, and an electromagnet member 50. The camera 10 is arranged on one side of the main vehicle group 102 or the follow-up vehicle group 103 close to the docking mechanism 100. The slideway 20 is arranged on the main vehicle pallet 104 of the main vehicle group 102. The slideway 20 includes a pair of side walls 21 arranged at intervals. A plurality of positioning holes 211 are formed in the side walls 21. The control chip 30 and the first driving member 40 are arranged in the slideway 20. The electromagnet member 50 is arranged at one end of the follow-up vehicle pallet 105 of the follow-up vehicle group 103. A plurality of positioning columns 51 are connected to both sides of the electromagnet member 50.

[0025] Specifically, the camera 10 is used to collect image information of the main vehicle group 102 and the accompanying vehicle group 103 when the main vehicle group 102 is docked with the accompanying vehicle group 103; the control chip 30 is used to control the electromagnet member 50 to be docked into the slideway 20 according to the image information; the control chip 30 is further used to obtain the distance information between the positioning posts 51 on both sides of the electromagnet member 50 and the positioning holes 211 in the slideway 20; the control chip 30 is further used to control the first driving member 40 to drive the electromagnet member 50 to slide in the slideway 20 according to the distance information; when the positioning posts 51 on both sides of the electromagnet member 50 are aligned with the positioning holes 211 in the slideway 20, the control chip 30 is further used to control the electromagnet member 50 to push the positioning posts 51 into the positioning holes 211, so as to fix the electromagnet member 50 in the slideway 20, and further realize the docking of the accompanying vehicle group 103 to the main vehicle group 102.

[0026] It can be understood that when the main vehicle group 102 is docked with the accompanying vehicle group 103, the camera 10 can collect image information of the main vehicle group 102 and the accompanying vehicle group 103. The control chip 30 controls the electromagnet member 50 to be docked into the slideway 20 according to the image information, and then obtains the distance information between the positioning post 51 and the positioning hole 211. The distance information can be sensed by a distance sensor, for example. The control chip 30 then controls the first driving member 40 to drive the electromagnet member 50 to slide in the slideway 20 so that the positioning post 51 is aligned with the positioning hole 211. Finally, the control chip 30 controls the electromagnet member 50 to push the positioning post 51 into the positioning hole 211 to fix the electromagnet member 50 in the slideway 20. Specifically, the electromagnet member 50 is an electromagnet system, which can generate an electric field and a magnetic field after being energized, and can drive the positioning post 51 to move back and forth, so as to fix or withdraw the electromagnet member 50 from the slideway 20.

[0027] Therefore, the docking mechanism 100 of the trailer group provided by the present invention can connect the main vehicle group 102 and the accompanying vehicle group 103. The docking mechanism 100 includes a camera 10, a slideway 20, a control chip 30, a first driving member 40 and an electromagnet member 50. The camera 10 is arranged on one side of the main vehicle group 102 or the accompanying vehicle group 103 close to the docking mechanism 100. The slideway 20 is arranged on the main vehicle pallet 104 of the main vehicle group 102. The slideway 20 includes a pair of side walls 21 arranged at intervals, and a plurality of positioning holes 211 are formed in the side walls 21. The control chip 30 and the first driving member 40 are arranged in the slideway 20. The electromagnet member 50 is arranged at one end of the accompanying vehicle pallet 105 of the accompanying vehicle group 103. A plurality of positioning columns 51 are connected to both sides of the electromagnet member 50. When the main vehicle group 102 is docked with the accompanying vehicle group 103, the camera 10 can collect the image information of the main vehicle group 102 and the accompanying vehicle group 103. The control chip 30 controls the electromagnet member 50 to be docked into the slideway 20 according to the image information, then obtains the distance information between the positioning column 51 and the positioning hole 211, and controls the first driving member 40 to drive the electromagnet member 50 to slide in the slideway 20 according to the distance information so that the positioning column 51 is aligned with the positioning hole 211. Finally, the control chip 30 controls the electromagnet member 50 to push the positioning column 51 into the positioning hole 211 to fix the electromagnet member 50 in the slideway 20, realizing the automatic docking of the accompanying vehicle group 103 to the main vehicle group 102. The docking method is easy to implement, the docking structure is simple, and the docking efficiency is improved.

[0028] The main vehicle group 102 includes a vehicle head and a main vehicle pallet 104 located on one side of the vehicle head and connected to the vehicle head. The main vehicle pallet 104 can be used to carry a box body 106 for loading goods. The box body 106 can be installed after the main vehicle group 102 is docked with the accompanying vehicle group 103. A plurality of wheels are arranged below the vehicle head and the main vehicle pallet 104. In this embodiment, a bearing plate 107 is formed by extending the side of the main vehicle pallet 104 away from the vehicle head, and the bearing plate 107 is used to carry the slideway 20.

[0029] In this embodiment, a camera 10 is arranged on one side of the main vehicle group 102 close to the docking mechanism 100, and a camera 10 is also arranged at one end of the accompanying vehicle group 103 close to the docking mechanism 100. The camera 10 is a mutual induction camera. The mutual induction camera is used to collect the image information of the main vehicle group 102 and the accompanying vehicle group 103 when the main vehicle group 102 is docked with the accompanying vehicle group 103. The relative position of the main vehicle group 102 and the accompanying vehicle group 103 can be obtained according to the collected image information, which is convenient for the docking of the main vehicle group 102 and the accompanying vehicle group 103. Specifically, the camera 10 is fixed on the slideway 20 on the main vehicle group 10.

[0030] The bottom surface of the main vehicle pallet 104 is provided with a main vehicle landing gear 11, and the bottom surface of the vehicle-mounted pallet 105 is provided with a vehicle-mounted landing gear 12. The control chip 30 is further configured to control the main vehicle landing gear 11 to adjust the lateral position of the main vehicle pallet 104 and control the vehicle-mounted landing gear 12 to adjust the longitudinal position of the vehicle-mounted pallet 105 according to the image information, so as to realize the docking of the electromagnet member 50 into the slideway 20. It can be understood that the control chip 30 has a control function, such as a micro-control unit, which is a control center for data reception, operation, and output. The main vehicle landing gear 11 and the vehicle-mounted landing gear 12 can be specifically connected to a driving member, capable of receiving a control signal and driving it to move.

[0031] Further, the main vehicle landing gear 11 can adjust the lateral position of the main vehicle group 102. The lateral direction is the length direction of the trailer group 101. The rollers of the main vehicle landing gear 10 can move forward and backward to adjust the lateral position of the main vehicle group 102. The main vehicle landing gear 11 includes a vertical rod fixed to the bottom surface of the bearing plate 107, a support rod sleeved with the vertical rod, and a roller provided at one end of the support rod. Specifically, the number of rollers is two, and the two rollers are connected by the main vehicle roller shaft of the main vehicle landing gear 11. The support rod can perform telescopic movement relative to the vertical rod in the vertical direction to fold the main vehicle landing gear 10 and reduce the occupied space. The main vehicle landing gear 11 further includes a support frame, and both ends of the support frame are respectively fixed to the vertical rod and the support rod. The support frame can be bent or unfolded to support the support rod when the support rod performs telescopic movement. In this embodiment, the vertical rod is further fixed to the edge plate of the bearing plate through a connecting rod to enhance the structural stability.

[0032] The vehicle-mounted landing gear 12 is used to adjust the longitudinal position of the vehicle-mounted group 103. The longitudinal direction is the direction perpendicular to the length direction of the trailer group 101. In this embodiment, the vehicle-mounted landing gear 12 is fixed on the vehicle-mounted pallet 105. The structure of the vehicle-mounted landing gear 12 is substantially the same as that of the main vehicle landing gear 11, and the direction of the vehicle-mounted roller shaft of the vehicle-mounted landing gear 12 is perpendicular to the direction of the main vehicle roller shaft of the main vehicle landing gear 11. The rollers of the vehicle-mounted landing gear 12 can move left and right to adjust the longitudinal position of the vehicle-mounted group 103. In this embodiment, a receiving groove can be opened on the bottom surface of the vehicle-mounted pallet 105 for receiving the vehicle-mounted landing gear 12 to prevent the vehicle-mounted landing gear 12 from occupying space. An auxiliary wheel 13 is provided on the bottom surface of the vehicle-mounted pallet 105. The auxiliary wheel 13 is fixed to the bottom surface of the vehicle-mounted pallet 105 through a vertical frame, and the auxiliary wheel 13 is used to assist in supporting the vehicle-mounted group 103.

[0033] The docking mechanism 100 of the trailer group provided by the present invention further includes a telescopic arm 60. The telescopic arm 60 is located on both sides of the vehicle-mounted pallet 105. One end of the telescopic arm 60 is fixed on the vehicle-mounted pallet 105, and the other end of the telescopic arm 60 is installed on the main vehicle pallet 104. The telescopic arm 60 is connected with a second driving member 61. The control chip 30 is further configured to control the second driving member 61 to drive the telescopic arm 60 to perform telescopic movement when the main vehicle group 102 is docked with the vehicle-following group 103, so as to enable the vehicle-following group to move in a direction close to or away from the main vehicle group. It can be understood that when the main vehicle group 102 is docked with the vehicle-following group 103, the second driving member 61 can drive the telescopic arm 60 to perform telescopic movement, and then drive the electromagnet member 50 to slide in the slideway 20, so as to enable the electromagnet member 50 to slide to the required position according to the actual transportation requirements, and further enable the trailer group 101 to reach the actual required length, and the length of the trailer group 101 can be adjusted according to the actual transportation requirements.

[0034] Specifically, a snap ring 130 is provided on the bottom surface of the main vehicle pallet 104. The snap ring 130 is provided with a limit hole, and a limit pin 14 is received in the limit hole. The snap ring 130 is used to insert the telescopic arm 60, and the limit pin 14 is used to clamp the telescopic arm 60 in the snap ring 130, so as to install the telescopic arm 60 on the main vehicle group 102.

[0035] The telescopic arm 60 includes a plurality of connecting pipes with gradually increasing diameters and sleeved in sequence. The plurality of connecting pipes with gradually increasing diameters and sleeved in sequence can realize the telescopic movement of the telescopic arm 60. In this embodiment, the connecting pipe with the largest diameter is fixed on the vehicle-following group 103 and connected to the second driving member 61, specifically fixed on both sides of the vehicle-mounted pallet 105. The connecting pipe with the smallest diameter is installed on the main vehicle group 102, and a slope is provided at one end of the connecting pipe with the smallest diameter close to the main vehicle group 102 for guiding during installation. One telescopic arm 60 is provided on each of the left and right sides of the vehicle-mounted pallet 105. After the main vehicle group 102 and the vehicle-following group 103 are combined, the two telescopic arms 60 provide a strong rigid support for the entire trailer, improving the structural stability.

[0036] Further, the connecting pipe with the smallest diameter is provided with a groove. The connecting pipe with the smallest diameter passes through the snap ring 130 on the bottom surface of the main vehicle pallet 104, and when the groove is aligned with the limit hole, the limit pin 14 can be clamped in the groove and the limit hole, so as to install the telescopic arm 60 on the main vehicle pallet 103. It can be understood that when the groove of the connecting pipe is not aligned with the limit hole of the snap ring 130, the limit pin 14 is pushed to the upper position of the snap ring 130 by the connecting pipe. When the groove of the connecting pipe is aligned with the limit hole of the snap ring, the limit pin 14 above the snap ring 130 automatically falls into the groove, and the connecting pipe is clamped, realizing the installation of the telescopic arm 60 on the main vehicle pallet 104.

[0037] The docking mechanism 100 of the trailer group provided by the present invention further includes a slider 70. The slider 70 is fixed at one end of the vehicle-mounted pallet 105. The slider 70 is provided with a receiving groove 701, and the electromagnet member 50 is received in the receiving groove 701.

[0038] Further, a strip-shaped groove 212 is provided on the side wall 21 of the slideway 20 close to the electromagnet member 50. The slider 70 includes side plates 71 located on both sides of the receiving groove 701. A rib 72 is provided on the side of the side plate 71 away from the electromagnet member 50. The rib 72 is clamped in the strip-shaped groove 212, and the rib 72 can slide along the strip-shaped groove 212, which has a guiding effect when the slider 70 is docked to the slideway 20. A plurality of through holes 702 are provided in the side plate 71 and the rib 72 and are arranged side by side. The positioning post 51 passes through the through holes 702. It can be understood that the electromagnet member 50 can drive the positioning post 51 to move. After the slider 70 is docked to the required position of the slideway 20, the electromagnet member 50 can receive the control signal of the control chip and drive the positioning post 51 to pass through the through holes 702 and the positioning holes 211, so as to fix the slider 70 in the slideway 50, and the docking of the main vehicle group 10 and the vehicle-mounted group 20 is completed.

[0039] It can be understood that the control chip 30 is a data receiving, computing, and output control center. When the main vehicle and the vehicle-mounted are docked and combined, it receives the information of the mutual inductance camera, and the computed information is then sent to the landing gear. The landing gear of the main vehicle adjusts the height direction, and the landing gear of the vehicle-mounted adjusts the left and right directions. After the main vehicle and the vehicle-mounted are docked and combined, it receives the distance between the drawer slideway hole (i.e., the positioning hole) and the positioning post, and the computed information is sent to the numerically controlled hydraulic cylinder to accurately push and pull the positioning post in the vehicle-mounted group to align with the slideway hole of the main vehicle group. When the drawer slideway hole is aligned with the positioning post, the information is transmitted to the control center, and the control center issues an instruction to the electromagnet system to push the positioning post into the drawer slideway hole to achieve the accurate docking of the main vehicle group and the vehicle-mounted group.

[0040] In this embodiment, a plurality of wire protection rings 22 are fixed on the side of the side wall 21 away from the slider 20. The wire protection rings 22 are used to clamp a plurality of cables 23 for realizing electrical connection between components. One end of the cable 23 is connected with a telescopic mechanism 231. The telescopic mechanism 231 is a tape-type telescopic mechanism, and the cables of the main vehicle group 102 and the vehicle-mounted group 103 can be freely pulled out and retracted, which is convenient for gathering and storing the cables when the length of the trailer group 101 is adjusted.

[0041] The docking mechanism 100 of the trailer group provided by the present invention. When the main vehicle group 102 is docked with the accompanying vehicle group 103, the camera 10 can collect the image information of the main vehicle group 102 and the accompanying vehicle group 103. The control chip 30 controls the main vehicle landing gear 104 to adjust the lateral position of the main vehicle group 102 and controls the accompanying vehicle landing gear 105 to adjust the longitudinal position of the accompanying vehicle group 103 according to the image information, so as to realize the docking of the electromagnet member 50 into the slideway 20. When it is necessary to adjust the length of the trailer group 101, the second driving member 61 drives the telescopic arm 60 to perform telescopic movement. The telescopic arm 60 drives the accompanying vehicle group 103 to move, so that the slider 70 accommodating the electromagnet member 50 is docked to the required position in the slideway 20. After moving to the required position, the control chip 30 obtains the distance information between the positioning columns 51 on both sides of the electromagnet member 50 in the slider 70 and the positioning holes 211 in the slideway 20, and controls the first driving member 40 to drive the slider 70 to slide in the slideway 20 for position fine-tuning according to the distance information. When the positioning columns 51 on both sides of the electromagnet member 50 are aligned with the positioning holes 211 in the slideway 20, the control chip 30 controls the electromagnet member 50 to push the positioning columns 51 into the positioning holes 211, so as to fix the electromagnet member 50 in the slideway 20, and further realize the precise docking of the accompanying vehicle group 103 and the main vehicle group 102. The docking method is easy to implement, the docking structure is simple, the docking efficiency is improved, and moreover, the overall length of the trailer group 101 can be adjusted during the docking process to meet the actual transportation requirements.

[0042] It can be understood that when the length of the trailer group 101 does not need to be adjusted, after the telescopic arm 60 drives the accompanying vehicle group 103 to move so that the slider 70 accommodating the electromagnet member 50 is docked to the default position in the slideway 20, the control chip 30 directly controls the first driving member 40 to drive the slider 70 to slide in the slideway 20 for position fine-tuning according to the distance information between the positioning columns 51 and the positioning holes 211. When the positioning columns 51 on both sides of the electromagnet member 50 are precisely aligned with the positioning holes 211 in the slideway 20, the control chip 30 controls the electromagnet member 50 to push the positioning columns 51 into the positioning holes 211 to complete the docking of the accompanying vehicle group 103 and the main vehicle group 102.

[0043] The first driving member 40 and the second driving member 51 are specifically numerically controlled hydraulic cylinders. The second driving member 61 can receive the control signal of the control chip 30 to drive the telescopic arm 60 to perform telescopic movement, so as to drive the slider 70 to dock to the required position in the slideway 20, meeting the required trailer length of the actual demand. The first driving member 40 is used to drive the slider 70 to slide in the slideway 20 for position fine-tuning, so that the positioning columns 51 on both sides of the electromagnet member 50 are aligned with the positioning holes 211 in the slideway 20.
