[0055] ​​Example implementations are now described with reference to the drawings. Example implementations can, however, be implemented in many different forms and should not be construed as limited to the implementations set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the inventive aspects of the example implementations to those skilled in the art. Like reference numerals refer to like elements throughout the views, and thus a detailed description of them will not be repeated.

[0056] It is to be understood that the terminology "including", "having" and "with" used herein, and any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, product or apparatus that comprises a list of steps or units are not necessarily limited to the listed steps or units, but can optionally further include additional steps or units not listed, or optionally further include steps or units inherent to such process, method, system, product or apparatus.

[0057] As shown in Figures 1 to 3 The unmanned delivery vehicle 10 of the embodiment of the present application comprises an unmanned vehicle 100, a support 200, a turnover frame 300 and a driving mechanism 400. The support 200 is installed on the unmanned vehicle 100; the turnover frame 300 is turnably connected to the support 200 between a first position P1 and a second position P2 (as shown in Figure 11 ); the driving mechanism 400 is arranged on the unmanned vehicle 100 and connected to the turnover frame 300, for driving the turnover frame 300 to turn relative to the support 200; wherein the turnover frame 300 has a loading position 301, and when the turnover frame 300 is located at the first position P1, the loading position 301 is used for loading a cage vehicle 20.

[0058] When loading, the turnover frame 300 is located at the first position P1, at this time the cage vehicle 20 can be loaded into the loading position 301 of the turnover frame 300; after the cage vehicle 20 is loaded into the loading position 301, the driving mechanism 400 drives the turnover frame 300 to turn from the first position P1 to the second position P2, and then the unmanned vehicle 100 carrying the cage vehicle 20 moves from the last station to the next station. After arriving at the target station, the driving mechanism 400 drives the turnover frame 300 to turn from the second position P2 to the first position P1, at this time the cage vehicle 20 can be taken off from the turnover frame 300, and the automatic loading and unloading of express delivery is completed.

[0059] As can be seen, the unmanned delivery vehicle 10 of the embodiment of the present application, through the design that the turnover frame 300 is turnably connected to the support 200 between the first position P1 and the second position P2, and the driving mechanism 400 drives the turnover frame 300 to turn relative to the support 200, realizes the automatic loading and unloading of the cage vehicle 20, significantly improves the efficiency of loading and unloading the cage vehicle 20, and reduces the labor cost.

[0060] As shown in Figure 8As shown, in one embodiment, the tilting frame 300 is welded from steel pipe and sheet metal, and includes a first part 310 and a second part 320. One end of the first part 310 is connected to one end of the second part 320, and the first part 310 and the second part 320 are perpendicularly connected to form an L-shape.

[0061] When the tilting frame 300 is tilted from the first position P1 to the second position P2, the tilting frame 300 is tilted at an angle of 90 degrees. Specifically, when the tilting frame 300 is in the first position P1, the first part 310 is horizontally set and the second part 320 is vertically set; when the tilting frame 300 is in the second position P2, the first part 310 is vertically set and the second part 320 is horizontally set.

[0062] In one implementation, such as Figure 3 As shown, the tilting frame 300 and the support member 200 can be connected by a pin. For example, the second part 320 of the tilting frame 300 is provided with a first connecting part 330, and the support member 200 is provided with two second connecting parts 220. The first connecting part 330 has a first connecting hole, and the second connecting part 220 has a second connecting hole. The first connecting part 330 is located between the two second connecting parts 220, and the positions of the first connecting hole and the second connecting hole correspond. The pin passes through the first connecting hole and the second connecting hole.

[0063] Of course, in other embodiments, the flipping frame 300 and the support member 200 can also be connected by a hinge.

[0064] like Figure 7 As shown, the unmanned vehicle 100 includes a vehicle body 110 and a cargo box 120, with the cargo box 120 mounted on the vehicle body 110. The cargo box 120 includes a receiving cavity 122 with an opening 121. A support member 200 is mounted on the vehicle body 110 and located within the receiving cavity 122. In a first position P1, the tilting frame 300 is located outside the cargo box 120; when tilting from the first position P1 to the second position P2, the tilting frame 300 tilts into the receiving cavity 122 through the opening 121.

[0065] In one embodiment, the body 120 has a top plate 123 and a side plate 124, which are connected. The opening 121 has a first opening 121a and a second opening 121b that are in communication with each other. The first opening 121a is located on the top plate 123, and the second opening 121b is located on the side plate 124.

[0066] In this embodiment of the application, not only is the side plate 124 provided with an opening, but the top plate 123 is also provided with an opening. In this way, when the tilting frame 300 is tilted, the tilting frame 300 does not need to be moved to the outside of the compartment 120, but can be tilted inside the compartment 120, and will not interfere with the top plate 123.

[0067] like Figure 3and Figure 13 As shown, the support member 200 is movably connected to the unmanned vehicle 100 between the third position P3 and the fourth position P4. The drive mechanism 400 is connected to the support member 200 and is used to drive the support member 200 to move when the tilting frame 300 is in the second position P2. Specifically, when the support member 200 moves from the third position P3 to the fourth position P4, the support member 200 drives the tilting frame 300 to move into the receiving cavity 122.

[0068] In other words, the drive mechanism 400 can both drive the tilting frame 300 to tilt between the first position P1 and the second position P2, and drive the support member 200 to translate between the third position P3 and the fourth position P4. The tilting of the tilting frame 300 and the translation of the support member 200 can be achieved by a single drive mechanism 400, which reduces the complexity and cost of the mechanism.

[0069] In one embodiment, the tilting axis of the tilting frame 300 is perpendicular to the moving direction of the support member 200. The tilting axis of the tilting frame 300 is parallel to the width direction of the unmanned vehicle 100.

[0070] It should be noted that the support member 200 reciprocates between the third position P3 and the fourth position P4 relative to the unmanned vehicle 100. In this embodiment, the direction of movement of the support member 200 is the forward and backward direction of the unmanned vehicle 100.

[0071] like Figure 3 As shown, the vehicle body 110 has a mounting base 111 located within the receiving cavity 122 of the body 120. The support member 200 is movably connected to the mounting base 111. It is understood that the mounting base 111 may be constructed from welded steel tubing and sheet metal, but is not limited thereto.

[0072] In one embodiment, the support member 200 and the fixed base 111 can be movably connected by a slide rail, but this is not a limitation. For example, in other embodiments, the support member 200 can also be movably connected to the fixed base 111 by a slide groove or rollers.

[0073] like Figure 1 As shown, the unmanned vehicle 100 also has a door 130 for opening or closing the opening 121. After the support member 200 moves the tipping frame 300 together with the cage 20 into the receiving cavity 122, the door 130 is closed, which can ensure the airtightness of the compartment 120 and prevent the express delivery in the cage 20 from accidentally falling off the unmanned vehicle 100 during transportation.

[0074] In one embodiment, the door 130 may be a roller shutter door, but it is not limited thereto. For example, in other embodiments, the door 130 may also be a sliding door, etc.

[0075] like Figures 4 to 6As shown, the drive mechanism 400 includes a connecting rod 410, a slider 420, and a drive assembly 430. The connecting rod 410 has a first connecting end and a second connecting end. The first connecting end is rotatably connected to the tilting frame 300, and the second connecting end is rotatably connected to the slider 420. The first connecting end and the second connecting end are located on opposite sides of the thickness direction of the support member 200. Along the moving direction of the support member 200, the slider 420 is movable relative to the support member 200. The drive assembly 430 is connected to the slider 420 and is used to drive the slider 420 to move along the moving direction of the support member 200, thereby driving the tilting frame 300 to tilt and the support member 200 to move via the slider 420.

[0076] In one embodiment, the slider 420 is movably connected to the support member 200, for example, via a slide rail or a slide groove. In another embodiment, the slider 420 can also be movably connected to the fixed base 111, for example, via a slide rail or a slide groove.

[0077] like Figure 12 As shown, the support member 200 is a flat plate structure and has a first surface 201 and a second surface 202. The first surface 201 and the second surface 202 are arranged opposite to each other along the thickness direction of the support member 200. The support member 200 also has a through hole 203 that penetrates the first surface 201 and the second surface 202. The through hole 203 is elongated and its length direction is parallel to the moving direction of the support member 200. The connecting rod 410 passes through the through hole 203, and the slider 420 is located on the side where the second surface 202 is located.

[0078] In this embodiment of the application, the connecting rod 410 is inserted into the elongated through hole 203. The through hole 203 can limit the connecting rod 410 and prevent the connecting rod 410 from shaking during movement.

[0079] The support member 200 also has a limiting portion 210 protruding from the second surface 202. When the support member 200 moves from the third position P3 to the fourth position P4, the slider 420 abuts against the limiting portion 210. When the flipping frame 300 flips from the first position P1 to the second position P2, the slider 420 moves toward the limiting portion 210.

[0080] Specifically, the slider 420 begins to move from its furthest point from the limiting part 210. As the slider 420 gradually approaches the limiting part 210, it pulls the flipping frame 300 from the first position P1 to the second position P2 via the connecting rod 410. When the flipping frame 300 flips to the second position P2, the slider 420 contacts the limiting part 210 or there is a slight gap between the slider 420 and the limiting part 210. The drive assembly 430 drives the slider 420 to continue moving closer to the limiting part 210. After the slider 420 abuts against the limiting part 210, it cannot move relative to the support member 200, and thus the slider 420 can move the support member 200 together. The distance the slider 420 moves after contacting the limiting part 210 is the distance the support member 200 moves from the third position P3 to the fourth position P4.

[0081] In one embodiment, the slider 420 and the support 200 can be movably connected by a slide rail, but this is not a limitation.

[0082] like Figure 4 and Figure 12 As shown, the slider 420 has a nut portion 421. The drive assembly 430 includes a lead screw 431 and a motor 432. The lead screw 431 is screwed to the nut portion 421; the motor 432 is connected to the lead screw 431 and is used to drive the lead screw 431 to rotate.

[0083] Of course, the drive assembly 430 is not limited to driving the motor 432 and the lead screw 431. For example, in other embodiments, the drive assembly 430 can also be a chain drive, a hydraulic cylinder, an electric cylinder, etc.

[0084] Next, combine Figures 7 to 13 The loading process of cage car 20 is described in detail.

[0085] like Figure 7 As shown, after the unmanned vehicle 100 arrives at the target station, it opens the door 130. At this time, the loading position 301 of the tipping frame 300 is not equipped with the cage car 20, and the tipping frame 300 is located in the second position P2, while the support member 200 is located in the fourth position P4.

[0086] like Figure 8 As shown, motor 432 drives lead screw 431 to rotate, and lead screw 431 drives slider 420 to move, so that slider 420 drives flipping frame 300 and support member 200 to move via connecting rod 410. When support member 200 moves from fourth position P4 to third position P3, slider 420 can no longer drive flipping frame 300 and support member 200 to continue moving. At this time, motor 432 drives lead screw 431 to continue rotating, and slider 420 drives flipping frame 300 from second position P2 to first position P1 via connecting rod 410. When flipping frame 300 is in first position P1, the first part 310 of flipping frame 300 is set horizontally, and the second part 320 is set vertically.

[0087] As shown in Figure 9 , the cage 20 is loaded into the loading position 301 of the turnover frame 300, and the cage 20 is fixed with the turnover frame 300.

[0088] As shown in Figure 10 and Figure 11 , after the cage 20 is fixed with the turnover frame 300, the motor 432 drives the screw rod 431 to rotate reversely to drive the sliding block 420 to move towards the direction close to the limiting part 210. With the movement of the sliding block 420, the sliding block 420 drives the turnover frame 300 to overturn from the first position P1 to the second position P2 through the connecting rod 410. When the turnover frame 300 overturns to the second position P2, the second part 320 of the turnover frame 300 is horizontally arranged, and the first part 310 is vertically arranged. At this time, the cage 20 is also horizontally arranged.

[0089] As shown in Figure 12 and Figure 13 , the motor 432 continues to drive the screw rod 431 to rotate, and after the sliding block 420 contacts with the limiting part 210, the sliding block 420 can push the support 200 to move from the third position P3 to the fourth position P4 until the support 200 moves to the fourth position P4. Finally, the door 130 of the unmanned vehicle 100 closes the opening 121 of the compartment 120.

[0090] It should be noted that, during the switching process of the turnover frame 300 from Figure 7 to Figure 8 , because the sliding block 420 is initially moved when the turnover frame 300 is in the second position P2, the weight of the turnover frame 300 or the weight of the turnover frame 300 and the cage 20 is relatively heavy, so that the driving force required for the sliding block 420 to drive the turnover frame 300 to overturn is relatively large, and the driving force required for the sliding block 420 to drive the support 200 to translate is relatively small. Therefore, when the motor 432 drives the sliding block 420 to move away from the limiting part 210 through the screw rod 431, the sliding block 420 will first drive the support 200 to translate, and then the sliding block 420 drives the turnover frame 300 to overturn when the support 200 moves to the third position P3.

[0091] In summary, the unmanned delivery vehicle 10 of the embodiment has at least the following advantages and beneficial effects:

[0092] The unmanned delivery vehicle 10 of the embodiment is designed that the turnover frame 300 is reversibly connected to the support 200 between the first position P1 and the second position P2, and the driving mechanism 400 drives the turnover frame 300 to overturn relative to the support 200, which realizes the automatic loading and unloading of the cage 20, significantly improves the efficiency of loading and unloading the cage 20, and significantly reduces the labor cost.
