[0034] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0036] like Figure 1 and Figure 2As shown, the present invention provides a loading and unloading device for an unmanned vehicle cargo box, including a support frame 3 and a driving device. The support frame 3 includes two oppositely arranged legs. A track 4 is arranged above the support frame 3. The two legs are respectively located at the two ends of the track 4. The track 4 is detachably connected to the two legs. A walking mechanism 5 is arranged on the track 4. The walking mechanism 5 is used to support the cargo box 2, and the walking mechanism 5 can move between the two ends of the track 4. The driving device is used to drive the track 4 to rise and fall.

[0037] Compared with the prior art, the support frame 3 is arranged on the outside of the unmanned vehicle, and the track 4 is detachably connected to the support frame 3 so that the track 4 extends into the vehicle body 1. First, the cargo box 2 is hoisted onto the track 4 outside the vehicle body 1, and the cargo box 2 forms a walking cooperation with the track 4 through the walking mechanism 5. At this time, the cargo box 2 can be conveniently moved to the track 4 inside the vehicle body 1, and then the track 4 is lifted and lowered by the driving device. In this way, the cargo box 2 on the track 4 can be accurately moved to a position that cooperates with the vehicle body 1, so that the installation of the cargo box 2 is realized, and then the track 4 is removed from the vehicle body 1; when disassembling the cargo box 2, the track 4 is lifted and lowered by the driving device, so that the cargo box 2 is separated from the vehicle body 1, and then the cargo box 2 is moved from the track 4 inside the vehicle body 1 to the track 4 outside the vehicle body 1; the above structure can conveniently replace the cargo box 2, avoid excessive manual participation in the operation, and improve the efficiency and accuracy of cargo box installation.

[0038] In some embodiments, Figure 1 and Figure 2 As shown, the legs include an upper leg 31 and a lower leg 32, the track 4 is detachably connected to the upper part of the two upper legs 31, the driving device is arranged between the upper leg 31 and the lower leg 32, and the driving device is used to drive the upper leg 31 to rise and fall relative to the lower leg 32. The legs are arranged on both sides of the vehicle body 1, and the track 4 is detachably connected to the upper legs 31 on both sides of the vehicle body 1 to achieve traversing the vehicle body 1. One side of the two sides of the vehicle body 1 is the replacement position of the cargo box 2, and slightly more legs should be arranged on this side to ensure stable support of the cargo box 2. The driving device drives the upper leg 31 to move up and down relative to the lower leg 32 to achieve driving the track 4 to rise and fall;

[0039] The legs may also be arranged only on the longitudinal rear side of the vehicle body 1. The track 4 and the upper leg 31 may be detachably connected and extend into the vehicle body 1. However, there is no support under the track 4 in the vehicle body 1. When the cargo box 2 moves onto the track 4 in the vehicle body 1, the track 4 may be deformed due to excessive load. This problem can be solved by adopting a track 4 with high structural strength.

[0040] In some embodiments, Figure 1 and Figure 2As shown, an upper crossbeam 33 is provided on the upper leg 31, and a lower crossbeam 34 is provided on the lower leg 32. The driving device adopts a telescopic mechanism 6, which is provided between the upper crossbeam 33 and the lower crossbeam 34. The upper end and the lower end of the telescopic mechanism 6 are connected to the upper crossbeam 33 and the lower crossbeam 34 respectively. As a preferred embodiment, the lower leg 32 can be composed of two lower support rods, and the lower crossbeam 34 is connected between the two lower support rods. The upper leg 31 can be composed of two upper support rods, and the upper crossbeam 33 is connected between the two upper support rods. The corresponding upper support rods and lower support rods are telescopically arranged. Of course, the arrangement of the legs of the present application is not limited to the above description. For example, when one of the two lateral sides of the vehicle body 1 is the replacement position of the cargo box 2, the lower leg 32 can be composed of four lower support rods, and the upper leg 31 can be composed of four upper support rods, so as to increase the structural stability of the legs. Those skilled in the art are capable of using other leg structures according to the above description to realize the arrangement of the upper leg 31 and the lower leg 32.

[0041] In some embodiments, Figure 3 As shown, the arrangement form of the telescopic mechanism 6 is as follows: it includes a first motor 61, a first driving rod 62 and a first rhombus telescopic member 63, the two corner points of the first rhombus telescopic member 63 in the horizontal direction are a first corner point 631 and a second corner point 632, the first motor 61 is used to drive one end of the first driving rod 62 to rotate, and the other end of the first driving rod 62 passes through the first corner point 631 and is threadedly connected with the second corner point 632. The first motor 61 directly drives the first driving rod 62 to rotate, the first motor 61 conflicts with the first corner point 631, and the first driving rod 62 and the second corner point 632 form a threaded rotation fit, thereby generating pressure or tension in the horizontal direction so that the first rhombus telescopic member 63 telescopes in the vertical direction. A fixing seat 633 is provided on the outer side of the first corner point 631, and the first motor 61 is arranged on the fixing seat 633, fixing the first motor 61 to prevent the first motor 61 from moving, and ensuring that the first rhombus telescopic member 63 can be stably telescoped.

[0042] In some embodiments, Figure 4As shown, the second arrangement form of the telescopic mechanism 6 includes a second motor 64, a second drive rod 65 and a second diamond-shaped telescopic member 66. The two corner points of the second diamond-shaped telescopic member 66 in the horizontal direction are the third corner point 661 and the fourth corner point 662. The second motor 64 is telescopically matched with one end of the second drive rod 65. The other end of the second drive rod 65 passes through the third corner point 661 and the fourth corner point 662 in sequence and is provided with a limit block 663. The limit block 633 is limitedly matched with the outer side of the fourth corner point 662. The second motor 64 and the second drive rod 65 constitute an electric telescopic rod structure commonly used in the prior art. The second motor 64 contacts the third corner point 661. The second motor 64 drives the second drive rod 65 to retract. The second drive rod 65 applies pressure to the fourth corner point 662 through the limit block 663 so that the second diamond-shaped telescopic member 66 is extended in the vertical direction. The second motor 64 drives the second drive rod 65 to extend. The second diamond-shaped telescopic member 66 is shortened in the vertical direction under the action of the load.

[0043] The diamond-shaped telescopic member is composed of four connecting plates, and the four connecting corners of the four connecting plates can be hinged by a hinge shaft to achieve the telescopic function. The telescopic mechanism 6 can also use devices with lifting functions such as telescopic cylinders commonly used in the prior art, but the use of the above devices has the following defects: if the track 4 is to be able to telescope with a stroke of L in the vertical direction, then the space height occupied by the telescopic cylinder in the vertical direction is at least 2L, which occupies too much space height, while the telescopic mechanism 6 of the present application adopts the driving principle of converting horizontal displacement into vertical displacement, and the space height occupied in the vertical direction is lower than 2L to achieve telescopic with a stroke of L, and the telescopic mechanism 6 can be arranged between the upper beam 33 and the lower beam 34, which reasonably utilizes the strip space formed between the upper beam 33 and the lower beam 34;

[0044] If the cargo box 2 is loaded with goods that are susceptible to collision or vibration, it is necessary to control the lifting and lowering of the cargo box 2 more smoothly and gently to avoid collision with the vehicle body 1. If the lifting stroke at this time is L, when a telescopic cylinder is used to extend and retract the distance L, a telescopic cylinder with high telescopic accuracy must be used. Otherwise, it is difficult to control the track 4 to be lifted and lowered more smoothly. The telescopic mechanism 6 of the present application adopts the driving principle of converting horizontal displacement into vertical displacement. The preferred shape of the diamond telescopic member is: the two corner points in the vertical direction are both obtuse angles, that is, the diamond telescopic member is in the shape of a flat strip; the diamond telescopic member is extended and retracted by a distance L in this state, and the control stroke of the motor in the horizontal direction is greater than L. At this time, the driving accuracy requirement of the motor is lower than that of the telescopic cylinder, and the lifting and lowering of the track 4 can be controlled more accurately and smoothly; and the use of the diamond telescopic member can further play a shock-absorbing role. When the cargo box 2 collides during loading and unloading, the force is shared and borne by both sides of the diamond telescopic member, thereby ensuring that the support frame 3 stably supports the cargo box 2 to the greatest extent.

[0045] In some embodiments, Figure 5 and Figure 6 As shown, the track 4 is provided with a receiving cavity in the length direction, and the traveling mechanism 5 and the receiving cavity form a sliding fit or a rolling fit in the length direction of the track 4, ensuring that the traveling mechanism 5 can carry the cargo box 2 and move quickly and conveniently along the length direction of the track 4.

[0046] Furthermore, the walking mechanism 5 forms a rolling fit with the accommodating cavity, the track 4 is provided with a T-slot 41 in the length direction, the T-slot 41 constitutes the accommodating cavity, the walking mechanism 5 includes a roller base 52 arranged in the T-slot 41, rollers 51 are arranged on both sides of the roller base 52, a support rod 53 extends from the roller base 52 relative to the notch of the T-slot 41, a support plate 54 is provided at the upper end of the support rod 53, mounting holes are provided at both ends of the T-slot 41, and a limit rod 42 is detachably connected in the mounting hole.

[0047] The roller 51 forms a sliding fit with the T-slot 41. The roller 51 can be detachably connected to the cargo box 2 or be independently arranged in the T-slot 41. The cargo box 2 can be moved along the length direction of the track 4 through the roller 51; the arrangement of the T-slot 41 is more convenient for limiting the walking mechanism 5, and only the support rod 53 extends relative to the T-slot 41 so that the roller base 52 and the roller 51 are embedded in the T-slot 41, preventing the walking mechanism 5 from moving irregularly and affecting the installation position of the cargo box 2; the limiting rod 42 limits the walking mechanism 5 in the length direction of the track 4.

[0048] In some embodiments, Figure 7 and Figure 8 As shown, the track 4 includes an inner track 43 in the vehicle body 1 and an outer track 44 outside the vehicle body 1, and the driving device is arranged in the vehicle body 1 to drive the inner track 43 to rise and fall. The track 4 needs to be disassembled and assembled every time the cargo box 2 is replaced, which will also take a certain amount of time accordingly, so the inner track 43 can be arranged in the vehicle body 1 of the unmanned vehicle, one side of the vehicle body 1 is the replacement position of the cargo box 2, and the support frame 3 is only arranged at the replacement position. The support frame 3 adopts the above-mentioned leg structure, and the outer track 44 is arranged on the leg structure. When the unmanned vehicle wants to replace the cargo box 2, the inner track 43 is flush with the outer track 44, and the cargo box 2 is transferred from the outer track 44 to the inner track 43, and then the driving device drives the track 4 to connect the cargo box 2 with the vehicle body 1.

[0049] Furthermore, the driving device includes a driving member 1 67 and a driving member 2 68. The driving member 1 67 is connected to the lower part of the outer track 44. The driving member 2 68 is provided with a U-shaped groove plate 69 that can be slidably connected to the lower part of the inner track 43. The driving member 2 68 can move to the side position of the vehicle body 1 along the length direction of the track 4. The joint between the inner track 43 and the outer track 44 may be unstable. The driving member 1 67 is fixed to the bottom plate of the vehicle body 1, which can limit the inner track 43 to only move up and down. The lower part of the driving member 2 682 is provided with a slide rail. The driving member 2 68 can move along the slide rail. When the inner track 43 and the outer track 44 are docked, the driving member 2 68 moves to the side position of the vehicle body 1 with the U-shaped groove plate 69. The U-shaped groove plate 69 extends out to connect with the outer track 44, thereby strengthening the connection stability of the joint and ensuring that the cargo box 2 can move stably between the inner track 43 and the outer track 44. In this embodiment, the driving member 1 67 and the driving member 2 68 can adopt the arrangement of the above-mentioned motor, driving rod and diamond-shaped telescopic member, and can also adopt the arrangement of telescopic cylinder.

[0050] like Figure 1 and Figure 2 As shown, an unmanned vehicle cargo box provided by the present invention includes a cargo box 2 body, on which a support portion is provided, and the cargo box 2 body can be set on the loading and unloading equipment of the unmanned vehicle cargo box through the support portion.

[0051] The support part can be an additional support structure provided on the body of the cargo box 2, or it can be a certain part on the body of the cargo box 2, so that the support part is arranged correspondingly on the walking mechanism 5, so that the cargo box 2 can be moved along the length direction of the track 4 through the walking mechanism 5.

[0052] In some embodiments, a hanger 22 is provided on the side of the cargo box 2 to cooperate with the traveling mechanism 5, and the hanger 22 is a support part. There are two tracks 4, which are arranged on both sides of the cargo box 2. Both sides of the cargo box 2 are provided with a hanger 22 to cooperate with the support plate 54. The hanger 22 can be L-shaped and can cooperate with the support plate 54 on the traveling mechanism 5.

[0053] like Figure 1 and Figure 2 As shown, the present invention provides an installation system for an unmanned vehicle cargo box, comprising a vehicle body 1, a cargo box 2 and the aforementioned loading and unloading equipment for the unmanned vehicle cargo box.

[0054] In some embodiments, the vehicle body 1 may be provided with a connector 1, and the cargo box 2 may be provided with a connector 2 corresponding to the connector 1, wherein the connector 1 is a groove / bump arranged on the bottom plate of the vehicle body 1, and the connector 2 is a bump / groove arranged at the bottom of the cargo box 2. When the cargo box 2 moves onto the track 4 in the vehicle body 1, the driving device drives the track 4 to descend, and the cargo box 2 falls, so that the bump / groove at the bottom of the cargo box 2 and the groove / bump on the bottom plate of the vehicle body 1 form a snap fit, thereby achieving accurate and stable installation of the cargo box 2.

[0055] Connector 1 and connector 2 may also be provided in the form of an S-shaped hook, with connector 1 being arranged on the top plate or side wall of vehicle body 1, and connector 2 being arranged on the top plate or side wall of cargo box 2. Cargo box 2 moves along track 4 into vehicle body 1, and the driving device drives track 4 up and down so that connector 1 is hooked with connector 2, thereby achieving a fixed connection between cargo box 2 and vehicle body 1.

[0056] In some embodiments, Figure 2 As shown, a rack 21 is provided on the cargo box 2, and the length direction of the rack 21 is parallel to the length direction of the track 4. A driving gear 11 that cooperates with the rack 21 is provided on the vehicle body 1; the vehicle body 1 is a box-shaped structure, and both sides of the vehicle body 1 are opened. The rack 21 is arranged on the top of the cargo box 2, and the driving gear 11 is arranged on the top plate of the vehicle body 1. A driving motor that provides power for the driving gear 11 is provided on the vehicle body 1. The driving device works to lift the track 4 to a height where the rack 21 and the driving gear 11 cooperate, and the position of the cargo box 2 is adjusted so that the rack 21 cooperates with the driving gear 11. The driving gear 11 cooperates with the rack 21 to move the cargo box 2 into the vehicle body 1. Then the driving device works to lower the track 4 to a set height, and the protrusions / grooves at the bottom of the cargo box 2 and the grooves / protrusions on the bottom plate of the vehicle body 1 form a snap fit, so that the precise and stable installation of the cargo box 2 is achieved.

[0057] The present invention provides a method for installing an unmanned vehicle cargo box, comprising the following steps:

[0058] Step 1: insert the track 4 into the vehicle body 1 and pass through the vehicle body 1;

[0059] Step 2: Install the track 4 onto the support frame 3. The support frame 3 is used to support the track 4, and the height of the support frame 3 is adjustable;

[0060] Step 3, placing the cargo box 2 on the portion of the track 4 located outside the vehicle body 1;

[0061] Step 4: Move the cargo box 2 along the track 4 to the interior of the vehicle body 1;

[0062] Step 5: Adjust the height of the support frame 3 so that the cargo box 2 falls into the vehicle body 1;

[0063] Step six: remove the track 4 from the support frame 3 and move the track 4 out of the vehicle body 1 .
