[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0036] See also Figures 1-10 In an embodiment of the present invention, a modular special unmanned vehicle with quick docking includes a vehicle body 1, wherein the vehicle body 1 includes a front end and a rear end, wherein a housing 3 and a frame 4 are fixedly provided at the front end and the rear end, respectively, and a connecting shaft 5 is fixedly provided on the frame 4;

[0037] The modular special unmanned vehicle for rapid docking also includes:

[0038] Two arc-shaped members 8 are movably provided at the front end of the vehicle body 1 , and each of the two arc-shaped members 8 is connected to a set of elastic telescopic mechanisms installed in the housing 3 , and the arc-shaped members 8 are adapted to the connecting shaft 5 ;

[0039] Two shaft sleeves 9 are movably provided at the front end of the vehicle body 1 and adapted to the connecting shaft 5. The two shaft sleeves 9 are connected to the two sets of elastic telescopic mechanisms through a movable driving mechanism. When the two adjacent vehicle bodies 1 are close to each other and the arc-shaped member 8 abuts against the connecting shaft 5, the two shaft sleeves 9 are respectively located at the two ends of the connecting shaft 5, and the movable driving mechanism is triggered to drive the shaft sleeves 9 to move along the axial direction of the connecting shaft 5, so that the two shaft sleeves 9 perform the docking action with the connecting shaft 5;

[0040] Two groups of state locking mechanisms are provided inside the housing 3 , and the state locking mechanisms are triggered after the two sleeves 9 and the connecting shaft 5 are connected, so as to maintain the connection state of the two adjacent vehicle bodies 1 .

[0041] Please refer again Figure 1 A set of tracks 2 is provided on both sides of the vehicle body 1. The tracks 2 are arranged in an inverted trapezoidal shape, which is used for allowing the vehicle body 1 to overcome obstacles and promote relative rotation between the shaft sleeve 9 and the connecting shaft 5 in the docking state.

[0042] Furthermore, in specific implementation, the vehicle body 1 can be used alone for operation. Under the special requirements of certain operations, multiple vehicle bodies 1 can be connected in series. The specific operation method is as follows:

[0043] The two vehicle bodies 1 to be connected are arranged one in front and one in back, the front vehicle is stationary, and the rear vehicle moves towards the front vehicle. Therefore, the arc-shaped member 8 of the rear vehicle will abut against the connecting shaft 5 of the front vehicle. At this time, the two shaft sleeves 9 are respectively located at both ends of the connecting shaft 5. As the rear vehicle continues to move, the elastic telescopic mechanism is triggered and causes the movable driving mechanism to move. Then, the movable driving mechanism drives the two shaft sleeves 9 to move closer to each other along the axial direction of the connecting shaft 5. Finally, the two shaft sleeves 9 are docked with the connecting shaft 5. Immediately, the state locking mechanism is triggered to lock the docking state of the two shaft sleeves 9 and the connecting shaft 5. In subsequent operations, when the front vehicle overcomes an obstacle, it will tilt backward. The two shaft sleeves 9 and the connecting shaft 5 enable the front vehicle and the rear vehicle to establish a rotational connection relationship, and the shaft sleeves 9 and the connecting shaft 5 rotate relative to each other. Therefore, through the mutual cooperation between various mechanisms and components, the rapid connection function of the vehicle is realized, without excessive manual operation, which is conducive to the rapid development of work and improves work efficiency.

[0044] Please refer again Figure 6 and Figure 8 The elastic telescopic mechanism includes a guide cylinder 6 fixedly mounted inside the housing 3, a telescopic rod 7 slidingly fitted with the guide cylinder 6, and a first cylindrical spring 18 arranged inside the telescopic rod 7, one end of the first cylindrical spring 18 is connected to the telescopic rod 7, and the other end is connected to the inner wall of the guide cylinder 6, and the arc-shaped member 8 is fixedly mounted on the end of the telescopic rod 7 away from the first cylindrical spring 18.

[0045] Please refer again Figure 5 、 Figure 7 as well as Figure 9 The movable drive mechanism includes two sets of sliding structures respectively connected to the two telescopic rods 7, and a rotating assembly located between the two telescopic rods 7 and connecting the two sets of sliding structures. The rotating assembly is connected to the two guide cylinders 6 via a sliding fit assembly. The sliding structure includes a cross arm 10 fixedly connected to the two telescopic rods 7. The ends of the cross arm 10 respectively pass through the two telescopic rods 7, and two sliders 11 are symmetrically slidably provided on the cross arm 10. The two sliders 11 are connected to the rotating assembly. The two shaft sleeves 9 are respectively fixedly connected to the two sliders 11. The rotating assembly can drive the two sliders 11 to move toward or away from each other along the length direction of the cross arm 10. The rotating assembly includes a disc 12 rotatably mounted on the cross arm 10 and two connecting rods 13 rotatably mounted on the disc 12. The connection between the connecting rod 13 and the disc 12 is located at the eccentric point of the disc 12, and a connecting column 16 is fixed to the bottom of the slider 11. The end of the connecting rod 13 away from the disc 12 is rotatably connected to the connecting column 16, and the rotating axis of the disc 12 is connected to the sliding fit assembly.

[0046] The sliding fit assembly includes a driven shaft 15 rotatably mounted on the cross arm 10 and a sleeve 17 fixedly connected to the two guide cylinders 6. The sleeve 17 slides and fits with the driven shaft 15, which is connected to the rotating shaft of the disc 12 via the bevel gear set 14. A driving post 1701 is fixedly mounted on the sleeve 17. A sliding groove 1501 adapted to fit the driving post 1701 is provided on the outer wall of the driven shaft 15. The sliding groove 1501 is spirally arranged, and the driving post 1701 extends into the sliding groove 1501 and is slidably connected to the driven shaft 15.

[0047] Specifically, the bevel gear set 14 includes a first bevel gear fixedly mounted on the end of the driven shaft 15 away from the vehicle body 1 and a second bevel gear fixedly mounted coaxially with the disc 12 , and the second bevel gear meshes with the first bevel gear.

[0048] When the two car bodies 1 are connected, the front car remains stationary and the rear car moves toward the front car, so the arc-shaped member 8 will eventually abut against the connecting shaft 5. At this time, the two bushings 9 are respectively located at the two ends of the connecting shaft 5 and remain concentric with the connecting shaft 5. Subsequently, the rear car continues to move, and the telescopic rod 7 and the cross arm 10 remain stationary. Accordingly, the guide cylinder 6 slides on the telescopic rod 7, the first column spring 18 is compressed, and the guide cylinder 6 drives the sleeve 17 to slide on the driven shaft 15 along the axial direction of the driven shaft 15 close to the bevel gear set 14, and the driving column 1701 makes a straight Linear movement, and since the slide groove 1501 is spirally arranged, the driving column 1701 can slide and cooperate with the driven shaft 15 through the slide groove 1501 during the movement, causing the driven shaft 15 to rotate, and then the driven shaft 15 drives the disc 12 to rotate through the bevel gear set 14, and the disc 12 pulls the slider 11 on the cross arm 10 toward the telescopic rod 7 through the connecting rod 13, and the two sliders 11 approach each other, that is, the two sleeves 9 slide to the end of the connecting shaft 5, so that a movable connection relationship is established between the front and rear car bodies 1, which is convenient for operation.

[0049] Please refer again Figure 6 、 Figure 8 as well as Figure 10The state locking mechanism includes a limit plate 24 movably disposed within the housing 3. The limit plate 24 is connected to an energy storage assembly installed within the housing 3 and engages with the cross arm 10 via a rolling structure. The rolling structure includes a connecting arm 25 fixed to the cross arm 10 and a roller 26 rotatably mounted on the end of the connecting arm 25 away from the cross arm 10. The roller 26 abuts against the limit plate 24. The limit plate 24 is formed with a long strip portion 2401 and a recessed portion 2402 in sequence along its length.

[0050] The energy storage assembly includes an electric push rod 19 mounted on the housing 3, a connecting seat 20 fixed to the movable end of the electric push rod 19, and two columns 21 fixed to the connecting seat 20 and slidably connected to the limiting plate 24;

[0051] A second cylindrical spring 22 is sleeved on the outer periphery of the column 21 , one end of the second cylindrical spring 22 is connected to the limiting plate 24 , and the other end is connected to a boss 23 fixed to the end of the column 21 away from the connecting seat 20 .

[0052] Attach Figure 10 For example, at this time, the vehicle is in an unconnected state, the roller 26 abuts against the long strip 2401, and the second cylindrical spring 22 is in a compressed state. During the connection process, when the first cylindrical spring 18 is compressed, the long strip 2401 and the recessed portion 2402 will pass through the roller 26 in sequence. When the sleeve 9 completes the docking action with the connecting shaft 5, the recessed portion 2402 reaches the roller 26, so the second cylindrical spring 22 rebounds, causing the limiting plate 24 to slide toward the connecting seat 20 on the two columns 21, and the recessed portion 2402 can limit the roller 26. Therefore, the first cylindrical spring 18 can maintain a compressed state, ensuring that the two sleeves 9 and the connecting shaft 5 maintain a docking state smoothly, thereby ensuring the stability of the connection between the front and rear vehicles.

[0053] When the connection between the front and rear vehicles needs to be released, the staff can remotely control the electric push rod 19 to drive the connecting seat 20 to rise until the roller 26 is pulled out from the recessed portion 2402, so that the locking state of the telescopic rod 7 is released. When the first cylindrical spring 18 rebounds, each component can be reset, and the two sleeves 9 are respectively pulled out from the two ends of the connecting shaft 5.
