[0054] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0055] It is understood that the terms "including" and "having" and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or components that are inherent to these processes, methods, products, or devices.

[0056] like Figure 1 As shown, the unmanned delivery vehicle of the embodiment of the present application comprises a carriage 1 and a cargo unloading device 2. The carriage 1 has a receiving chamber 1a, and the cargo unloading device 2 is located in the receiving chamber 1a.

[0057] The present application does not particularly limit the shape of the carriage 1. For example, the carriage 1 may be a cube, a cylinder, or other regular or irregular shapes.

[0058] like Figures 2 to 4As shown, the unloading device 2 of the embodiment of the present application includes a frame 10, a conveying mechanism 20 and an unloading mechanism 30. The frame 10 is arranged in the accommodating chamber 1a and is fixedly connected to the carriage 1. The unloading mechanism 30 includes a moving assembly 100, a ramp assembly 200 and a flip assembly 300. The moving assembly 100 is movably connected to the frame 10 between a first position and a second position along the front-to-back direction D1 (the direction indicated by the arrow is the front, and the reverse direction is the rear), the ramp assembly 200 is rotatably connected to the moving assembly 100, and the flip assembly 300 is connected to the ramp assembly 200 and the moving assembly 100, and is used to drive the ramp assembly 200 to rotate relative to the moving assembly 100. The conveying mechanism 20 is installed on the frame 10, and the conveying mechanism 20 has a conveying surface 21 for supporting goods, and the conveying surface 21 is used to convey goods along the front-to-back direction D1, and convey the goods to the ramp assembly along the front-to-back direction D1. When the moving assembly 100 is located at the first position, the ramp assembly 200 is located in the frame 10 ; when the moving assembly 100 is located at the second position, at least a portion of the ramp assembly 200 extends out of the frame 10 .

[0059] In the unmanned delivery vehicle of the embodiment of the present application, the moving component 100 can drive the ramp component 200 and the flip component 300 to move along the front-to-back direction D1. When the moving component 100 is located in the first position, the ramp component 200 is located in the frame 10. At this time, the moving component 100 and the ramp component 200 will not affect the goods stored on the conveying surface 21 of the conveying mechanism 20; when the moving component 100 is located in the second position, at least part of the ramp component 200 extends out of the frame 10, and the flip component 300 drives the ramp component 200 to rotate to a tilted state. At this time, the conveying mechanism 20 conveys the goods along the front-to-back direction D1 and conveys the goods to the ramp component 200. Under the action of the gravity of the goods themselves, the goods slide along the ramp component 200 to achieve automatic unloading.

[0060] Therefore, when the unmanned delivery vehicle of the embodiment of the present application arrives at the unloading point, the conveying mechanism 20, the moving component 100, the ramp component 200 and the flip component 300 can realize the automatic unloading of the goods without waiting for the picker to pick up the goods manually, which significantly improves the delivery efficiency. In addition, when the unmanned delivery vehicle is used in a serial delivery environment, the goods at each delivery station can be unloaded on time, avoiding the problem of delivery timeout at subsequent stations due to delivery timeout at a certain station.

[0061] like Figure 3 As shown, the frame 10 includes a frame body 18, and the frame body 18 is fixedly connected to the carriage 1. The frame body 18 may include a plurality of cross beams and a plurality of longitudinal beams, and the plurality of cross beams and the plurality of longitudinal beams are interconnected to form a cubic frame.

[0062] For example, the frame body 18 includes two first longitudinal beams 18a, two second longitudinal beams 18b, two bottom beams 18c, two first cross beams 18d and one second cross beam 18e. The two bottom beams 18c are arranged at intervals along the left-right direction D3 (the direction indicated by the arrow is left, and the reverse direction is right), and each bottom beam 18c is fixedly connected to the bottom wall of the carriage 1. The two first longitudinal beams 18a are respectively connected to the front ends of the two bottom beams 18c, and each first longitudinal beam 18a extends along the up-down direction D2 (the direction indicated by the arrow is up, and the reverse direction is down). The two second longitudinal beams 18b are respectively connected to the rear ends of the two bottom beams 18c, and each second longitudinal beam 18b extends along the up-down direction D2. The first longitudinal beam 18a and the second longitudinal beam 18b connected to the same bottom beam 18c are arranged at intervals along the front-back direction D1. The two ends of the two first cross beams 18d are respectively connected to the upper end of the first longitudinal beam 18a and the upper end of the second longitudinal beam 18b located on the same side of the frame body 1818. Both ends of the second horizontal beam 18e are connected to the upper ends of the two second longitudinal beams 18b, respectively.

[0063] The two first longitudinal beams 18 a form an exit 13 for goods to slide out; wherein the direction of the exit 13 is the front-rear direction D1 .

[0064] The frame body 18 also includes two first side beams 18f, a second side beam 18g and an intermediate beam 18h. The two first side beams 18f are arranged at intervals along the left-right direction D3, and the two ends of the two first side beams 18f are respectively connected to the non-ends of the first longitudinal beam 18a and the second longitudinal beam 18b located on the same side of the frame body 18. The second side beam 18g extends along the left-right direction D3, and the two ends of the second side beam 18g are respectively connected to the non-ends of the two second longitudinal beams 18b. Among them, the second side beam 18g can be aligned with the two first side beams 18f respectively. The two ends of the intermediate beam 18h are respectively connected to the middle parts of the two first side beams 18f.

[0065] The conveying mechanism 20 is installed on the frame body 18 , and the moving assembly 100 is movably connected to the frame body 18 along the front-rear direction D1 .

[0066] It is understood that the conveying mechanism 20 of the present application includes one or more conveying units 20a, and a plurality refers to more than two. When the conveying mechanism 20 includes a plurality of conveying units 20a, the plurality of conveying units 20a are arranged side by side along the left-right direction D3. Among them, the front-to-back direction D1, the up-down direction D2, and the left-to-right direction D3 are mutually perpendicular. Each conveying unit 20a has a conveying surface 21, and each conveying unit 20a conveys goods along the front-to-back direction D1.

[0067] The present application does not specifically limit the type of the conveying unit 20a, for example, the conveying unit 20a may be a belt conveyor, a roller conveyor, etc. When the conveying mechanism 20 includes a plurality of conveying units 20a, the types of the plurality of conveying units 20a may be the same or different, for example, the plurality of conveying units 20a may all be belt conveyors or roller conveyors, or some of the conveying units 20a may be belt conveyors, and the other portion of the conveying units 20a may be roller conveyors.

[0068] It should be noted that the number of conveying units 20a included in the conveying mechanism 20 can be determined according to the number of serial points that the unmanned delivery vehicle needs to deliver. For example, when the number of serial points of the unmanned delivery vehicle is one, the conveying mechanism 20 includes one conveying unit 20a. When the unmanned delivery vehicle arrives at the delivery point, the conveying unit 20a works and all the goods are unloaded; when the number of serial points of the unmanned delivery vehicle is multiple, the number of conveying units 20a included in the conveying mechanism 20 is the same as the number of serial points, for example, there are two conveying units 20a. When the unmanned delivery vehicle arrives at the first delivery point, one of the conveying units 20a works, and the goods on the conveying unit 20a are unloaded, while the other conveying unit 20a does not work; when the unmanned delivery vehicle arrives at the second delivery point, the other conveying unit 20a works, and the goods on the other conveying unit 20a are unloaded.

[0069] like Figure 3 As shown, optionally, the frame 10 may further include at least one partition 19, which is fixedly connected to the frame body 18. When the conveying mechanism 20 includes a plurality of conveying units 20a, a partition 19 is provided between two adjacent conveying units 20a along the left-right direction D3, and the partition 19 is used to separate the goods on the two adjacent conveying units 20a.

[0070] The frame 10 further includes two side plates 11 and two inclined plates 12. The two side plates 11 are respectively located on both sides of the conveying mechanism 20 along the left-right direction D3. In addition, the two side plates 11 are arranged in parallel and are respectively connected to the first longitudinal beam 18a, the second longitudinal beam 18b and the first transverse beam 18d on the same side of the frame 10. The two inclined plates 12 are respectively connected to one end of the two side plates 11 along the front-back direction D1, and the two inclined plates 12 extend obliquely from the corresponding side plates 11 toward the direction of approaching each other and toward the exit 13.

[0071] In the embodiment of the present application, the frame 10 also has two inclined plates 12 extending obliquely. When the conveying surface 21 of the conveying mechanism 20 conveys goods, the two inclined plates 12 can gather the goods to the middle position of the outlet 13 along the left-right direction D3, thereby preventing the goods from sliding out from the side of the ramp component 200 when sliding along the ramp component 200.

[0072] Please continue reading Figure 3The frame 10 further includes two reinforcing plates 15, one end of each of the two reinforcing plates 15 is connected to one end of the inclined plate 12 away from the side plate 11, and the other end of each of the two reinforcing plates 15 is connected to the frame body 18. By providing the reinforcing plates 15, the stability of the inclined plate 12 can be improved.

[0073] As an example, the corresponding side plates 11, the inclined plates 12 and the reinforcing plates 15 may be formed by bending a flat plate, but the present invention is not limited thereto.

[0074] like Figure 3 and Figure 4 As shown, the ramp assembly 200 has a ramp surface 201 for guiding the goods to slide down. The ramp assembly 200 is rotatably connected to the moving assembly 100 between the third position and the fourth position. In other words, the flip assembly 300 can drive the ramp assembly 200 to rotate between the third position and the fourth position. In the third position, the ramp surface 201 is parallel to the conveying surface 21; in the fourth position, the ramp surface 201 and the conveying surface 21 present a target angle α (such as Figure 8 ).

[0075] Among them, the target angle α can be between 20° and 80°. Preferably, the target angle α can be between 30° and 60°, for example, α is 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc.

[0076] It can be understood that by designing the target angle α between the ramp surface 201 and the conveying surface 21 to be between 30° and 60°, on the one hand, the speed at which the goods slide down the ramp component 200 can be ensured to avoid the speed being too slow or even the goods stopping sliding; on the other hand, it can also avoid the target angle α being too large, resulting in the goods sliding too fast and damaging the goods.

[0077] like Figure 4 As shown, the ramp assembly 200 is rotatably connected to the moving assembly 100 around a rotation axis L, and the rotation axis L is perpendicular to the front-to-back direction D1 and the up-down direction D2, that is, the rotation axis L is parallel to the left-right direction D3.

[0078] Please continue reading Figure 4 The flip assembly 300 of the embodiment of the present application includes a first driving member 310 and a rocker arm 320. The first driving member 310 includes a first fixed portion 311 and a first telescopic portion 312. The first fixed portion 311 is hinged to the moving assembly 100, and the first telescopic portion 312 is telescopically connected to the first fixed portion 311. One end of the rocker arm 320 in the length direction is hinged to the first telescopic portion 312, and the other end of the rocker arm 320 in the length direction is fixedly connected to the ramp assembly 200.

[0079] When the first telescopic portion 312 is telescoped relative to the first fixed portion 311 , the first telescopic portion 312 can drive the rocker arm 320 to rotate around the rotation axis L, thereby driving the ramp assembly 200 to rotate between the third position and the fourth position.

[0080] The number of the flip assembly 300 can be one or two. When the number of the flip assembly 300 is one, the flip assembly 300 is disposed on one side of the moving assembly 100 along the left-right direction D3. When the number of the flip assembly 300 is two, the two flip assemblies 300 are disposed on both sides of the moving assembly 100 along the left-right direction D3.

[0081] As an example, the first driving member 310 may be an electric push rod, the base of the electric push rod is the first fixed portion 311, and the push rod of the electric push rod is the first telescopic portion 312. Of course, in other embodiments, the first driving member 310 may also be a pneumatic push rod, a hydraulic push rod, etc.

[0082] like Figure 3 As shown, the frame 10 also has a rack 14, which is fixedly connected to the frame body 18, and the length direction of the rack 14 is parallel to the front-rear direction D1. Figure 5 As shown, the moving assembly 100 includes a moving frame 110, a motor 120 and a gear 130. The moving frame 110 is movably connected to the frame body 18 of the frame 10 between a first position and a second position along the front-back direction D1. The motor 120 is mounted on the moving frame 110; the gear 130 is drivingly connected to the output shaft of the motor 120, and the gear 130 is meshed with the rack 14.

[0083] When the motor 120 rotates forward, the motor 120 can drive the gear 130 to rotate. Since the rack 14 is fixedly connected to the frame body 18, the movable frame 110, the motor 120 and the gear 130 can move from the first position to the second position; when the motor 120 rotates reversely, the movable frame 110, the motor 120 and the gear 130 can move from the second position to the first position.

[0084] Of course, in other embodiments, the gear 130 and the rack 14 may also be replaced by a non-self-locking worm gear.

[0085] Continue reading Figure 3 and Figure 5The rack 10 includes two racks 14, which are arranged at intervals along the left-right direction D3 and are respectively fixedly connected to the two bottom beams 18c. The moving assembly 100 also includes a transmission shaft 140 and a transmission unit 150. A gear 130 is respectively provided at both axial ends of the transmission shaft 140. The two gears 130 are respectively meshed with the two racks 14. The output shaft of the motor 120 is connected to the transmission shaft 140 through the transmission unit 150. When the motor 120 is working, the transmission shaft 140 drives the two gears 130 to rotate synchronously, thereby realizing the movement of the moving assembly 100 along the front-back direction D1.

[0086] In one embodiment, the transmission unit 150 may be a synchronous belt transmission mechanism, which includes two synchronous wheels and a synchronous belt, wherein one synchronous wheel is connected to the output shaft of the motor 120 , and the other synchronous wheel is connected to the transmission shaft 140 , and the synchronous belt is wound around the outer circumference of the two synchronous wheels.

[0087] In other embodiments, the transmission unit 150 may also be a chain transmission mechanism, a gear transmission mechanism, a worm gear transmission mechanism, etc.

[0088] like Figure 4 and Figure 6 As shown, the ramp assembly 200 includes a first ramp 210, a second ramp 220 and a second driving member 230. The first ramp 210 has a ramp surface 201, and the first ramp 210 is rotatably connected to the moving assembly 100 and connected to the rocker arm 320 of the flip assembly 300. The second ramp 220 is telescopically connected to the first ramp 210. The second driving member 230 includes a second fixed portion 231 and a second telescopic portion 232, the second fixed portion 231 is connected to the first ramp 210, the second telescopic portion 232 is telescopically connected to the second fixed portion 231 along the extension direction of the second ramp 220 relative to the first ramp 210, and the second telescopic portion 232 is connected to the second ramp 220.

[0089] In the embodiment of the present application, the ramp assembly 200 includes a first ramp 210 and a second ramp 220. The second ramp 220 is telescopically connected to the first ramp 210, so that the ramp assembly 200 forms a two-stage type. On the one hand, when the two-stage ramp assembly 200 is in a retracted state, the size of the ramp assembly 200 is narrow, which is convenient for the ramp assembly 200 to be stored in the frame 10; on the other hand, the second ramp 220 is telescopically connected to the first ramp 210, so that the length of the ramp assembly 200 is adjustable, thereby adapting to unloading points of different heights, for example, when the unloading point is located on the ground, on a curb, or on a platform with a certain height; on the other hand, when the ramp assembly 200 is retracted, the second driving member 230 first drives the second ramp 220 to retract, and then the first driving member 310 drives the ramp assembly 200 to rotate to the third position. That is to say, during the retraction of the ramp assembly 200 , the second ramp 220 is first retracted and then flipped, which can avoid directly flipping the ramp assembly 200 and causing some goods to remain on the ramp assembly 200 , affecting the normal retraction of the ramp assembly 200 .

[0090] In one embodiment, the ramp assembly 200 further includes a sensor 240, which is connected to a side of the second ramp 220 away from the first ramp 210, and the sensor 240 is used to generate a stop signal to stop the second telescopic portion 232 from extending. When the second ramp 220 is extended relative to the first ramp 210, and the sensor 240 encounters an obstacle and generates a stop signal, the second telescopic portion 232 will no longer extend further.

[0091] As an example, a controller may be provided in the unmanned delivery vehicle, and the controller is connected to the sensor 240 and the second driving member 230 by signal. The controller can control the second telescopic portion 232 of the second driving member 230 to stop extending according to the stop signal generated by the sensor 240. Of course, in other embodiments, the controller may also be provided on a cloud server.

[0092] In one embodiment, the sensor 240 may be an edge switch, but is not limited thereto.

[0093] As an example, the second driving member 230 may be an electric push rod, the base of the electric push rod is the second fixing portion 231, and the push rod of the electric push rod is the second telescopic portion 232. Of course, in other embodiments, the second driving member 230 may also be a pneumatic push rod, a hydraulic push rod, etc.

[0094] like Figure 6 and Figure 7As shown, the second slope 220 includes a first sub-slope 221, a second sub-slope 222 and a linkage assembly 223. The first sub-slope 221 is telescopically connected to the first slope 210, and the first sub-slope 221 is connected to the second telescopic portion 232; the second sub-slope 222 is telescopically connected to the first sub-slope 221 along the telescopic direction of the first sub-slope 221 relative to the first slope 210; the linkage assembly 223 is respectively connected to the first slope 210, the first sub-slope 221, and the second sub-slope 222, so that the first sub-slope 221 and the second sub-slope 222 are linked.

[0095] In the embodiment of the present application, the first sub-slope 221 of the slope assembly 200 can be telescopic relative to the first slope 210, and the second sub-slope 222 can be telescopic relative to the first sub-slope 221, so that the slope assembly 200 forms a multi-stage telescopic slope structure, which increases the length of the slope assembly 200 when it is in an extended state to a certain extent, thereby expanding the scope of application; in addition, the first sub-slope 221 and the second sub-slope 222 are linked, and when the second telescopic portion 232 is telescopic relative to the second fixed portion 231, the first sub-slope 221 can be telescopic relative to the first slope 210, and the second sub-slope 222 can be telescopic relative to the first sub-slope 221, without the need to additionally set a driving member for the second sub-slope 222, so that the structure of the slope assembly 200 is simple and the cost is low.

[0096] In one embodiment, the second slope 220 includes two linkage components 223 , and the two linkage components 223 are spaced apart along the left-right direction D3 .

[0097] like Figure 6 and Figure 7 As shown, the linkage assembly 223 includes two rollers 2231 and an annular linkage member 2232. The two rollers 2231 are connected to the first sub-slope 221; the two rollers 2231 are arranged at intervals along the extension direction of the first sub-slope 221 relative to the first slope 210; the annular linkage member 2232 is arranged around the outer circumference of the two rollers 2231; the annular linkage member 2232 has two parallel connection sections 2232a, and the two connection sections 2232a are fixedly connected to the first slope 210 and the second sub-slope 222 respectively.

[0098] Figure 6 and Figure 7 The second sub-slope 222 and the first sub-slope 221 are shown in the maximum extension state. When the second telescopic portion 232 retracts, the annular linkage member 2232 rotates counterclockwise, thereby achieving the retraction of the second sub-slope 222 relative to the first sub-slope 221, and the retraction of the first sub-slope 221 relative to the first slope 210. In addition, the retraction speed of the second sub-slope 222 is twice the retraction speed of the first sub-slope 221.

[0099] Similarly, when the second telescopic portion 232 is extended, the annular linkage member 2232 rotates clockwise, thereby achieving the extension of the second sub-slope 222 relative to the first sub-slope 221, and the extension of the first sub-slope 221 relative to the first slope 210. In addition, the extension speed of the second sub-slope 222 is twice that of the first sub-slope 221.

[0100] It is understandable that the roller 2231 can be a fixed pulley, and the annular linkage 2232 is a wire rope. Of course, as an alternative embodiment, the roller 2231 can also be a synchronous wheel, and the annular linkage 2232 is a synchronous belt.

[0101] like Figure 8 As shown, the frame 10 also includes a transition piece 16, which is connected between the two first longitudinal beams 18a of the frame body 18, and the transition piece 16 has an inclined surface 16a; wherein, when the ramp assembly 200 is located at the fourth position, the inclined surface 16a is parallel to the ramp surface 201, and the inclined surface 16a is used to guide the goods to slide from the conveying surface 21 to the ramp surface 201.

[0102] In the embodiment of the present application, by providing the transition piece 16 , the gap between the conveying mechanism 20 and the slope assembly 200 can be covered, thereby allowing the goods to slide more smoothly from the conveying surface 21 to the slope surface 201 .

[0103] like Figure 8 As shown, the frame 10 further includes a stopper 17, which is mounted on the first longitudinal beam 18a. When the ramp assembly 200 is located at the fourth position, the stopper 17 abuts against the rocker arm 320. By setting the stopper 17, the maximum inclination angle of the ramp assembly 200 can be controlled.

[0104] In summary, the unloading device 2 and the unmanned delivery vehicle of the embodiment of the present application have at least the following advantages and beneficial effects:

[0105] The unloading device 2 and the unmanned delivery vehicle of the embodiment of the present application can realize automatic unloading of goods when the unmanned delivery vehicle arrives at the unloading point under the joint action of the conveying mechanism 20, the moving component 100, the ramp component 200 and the flip component 300, without waiting for the picker to manually pick up the goods, which significantly improves the delivery efficiency. In addition, when the unmanned delivery vehicle is used in a serial point delivery environment, the goods at each delivery station can be unloaded on time, avoiding the problem of timeouts at subsequent stations due to timeouts at a certain station.
