Technical Field

[0001] The utility model relates to the technical field of logistics distribution equipment, in particular to a loading and flipping device and a logistics autonomous vehicle. Background Art

[0002] With the development of technology, unmanned devices are applied to various fields. In the logistics industry, in order to make distribution more intelligent, each company is trying the express unmanned distribution service. During the unmanned distribution process: parcels start from the unmanned warehouse, are quickly transported to the sorting center by driverless heavy trucks, and then are loaded onto the last-mile unmanned delivery vehicle and delivered to customers. The unmanned delivery vehicle is a product that appears in response to the current end-distribution market and the development of driverless technology. Its main purpose is to complete the handling of cages, and the cage is a container for express delivery. The cage is transferred or distributed by the unmanned delivery vehicle.

[0003] The existing loading component of the unmanned delivery vehicle can perform autonomous sliding and flipping to complete the loading and unloading of the cage. However, during the sliding process of the loading component relative to the vehicle body, the friction between the loading component and the vehicle frame is large, the energy consumption of the unmanned delivery vehicle is large, resulting in a high use cost of the unmanned delivery vehicle and low distribution efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a loading and flipping device and a logistics autonomous vehicle, which can save energy consumption, reduce the use cost, and improve the distribution efficiency.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0007] A frame, on which two guiding surfaces are arranged at intervals along the Y direction, and along the X direction, both of the two guiding surfaces extend obliquely away from the frame;

[0008] A power mechanism, arranged on the frame;

[0009] A transmission mechanism, including a transmission component and two groups of roller guiding components. The two groups of roller guiding components are arranged at intervals along the Y direction on the transmission component and are both in rolling cooperation with the frame. The transmission component is in transmission connection with the power mechanism;

[0010] A loading mechanism, rotatably connected to a connecting rod in the transmission component;

[0011] The power mechanism can drive the loading mechanism to move along the guiding surface through the transmission component, so that the loading mechanism flips in a direction close to or away from the frame.

[0012] As a further technical solution, the frame includes two support shafts arranged at intervals in the Y direction, and the two roller guiding assemblies are correspondingly arranged on the transmission assembly with the two support shafts;

[0013] Each of the roller guiding assemblies includes a first guiding wheel, and the first guiding wheel is rotatably connected to the transmission assembly and is in rolling cooperation with the upper end surface of the corresponding support shaft.

[0014] As a further technical solution, each of the roller guiding assemblies includes a second guiding wheel and a first guiding groove. The first guiding groove is arranged on the corresponding support shaft and extends in the X direction. The second guiding wheel is rotatably connected to the transmission assembly and is in rolling cooperation with the corresponding first guiding groove.

[0015] As a further technical solution, the roller guiding assembly further includes a third guiding wheel. The third guiding wheel is rotatably connected to the transmission assembly and is in rolling cooperation with the corresponding support shaft. And in the Y direction, the second guiding wheel and the third guiding wheel are respectively arranged on both sides of the corresponding support shaft.

[0016] As a further technical solution, the transmission assembly includes a support plate and a connecting member;

[0017] Two groups of the roller guiding assemblies are arranged on the support plate at intervals in the Y direction. The support plate is connected to the power mechanism through the connecting member, and two ends of the connecting rod are respectively rotatably connected to the support plate and the loading mechanism.

[0018] As a further technical solution, the frame further includes two guiding members and two guiding wheels. The two guiding members are correspondingly arranged on the two support shafts, and a reinforcing member is arranged on the guiding member;

[0019] The upper end surfaces of the two guiding members both serve as the guiding surfaces, and the two guiding wheels are correspondingly arranged on the loading mechanism with the two guiding members and are both in rolling cooperation with the corresponding guiding surfaces.

[0020] As a further technical solution, the loading mechanism includes a bottom bracket and two baffles. The two baffles are arranged on the upper end surface of the bottom bracket at intervals in the X direction, and the connecting rod is rotatably connected to the lower end surface of the bottom bracket.

[0021] As a further technical solution, the power mechanism includes a driving member, a first chain, and a driven shaft;

[0022] The driving member is fixedly arranged on the frame, the driven shaft is rotatably connected to the frame, and along the X direction, the driving member and the driven shaft are arranged at intervals relative to each other. The output shaft of the driving member and the driven shaft are connected by the first chain, and the transmission assembly is connected to the first chain.

[0023] As a further technical solution, the power mechanism includes a reduction shaft and a second chain. The reduction shaft is rotatably connected to the frame and is located between the driving member and the driven shaft.

[0024] The logistics unmanned vehicle includes a vehicle body and a loading and turning device, and the loading and turning device is arranged on the vehicle body.

[0025] Compared with the prior art, the technical advantages of the loading and turning device and the logistics unmanned vehicle provided by the present utility model are as follows:

[0026] 1. Since both sets of roller guiding components are in rolling cooperation with the frame, when the power mechanism operates, the transmission component drives the loading mechanism to move along the guiding surface, causing the loading mechanism to turn towards or away from the frame. During this process, the two sets of roller guiding components not only guide the transmission component to move along the frame, but also, during the movement of the transmission component along the frame, due to the rolling cooperation of both sets of roller guiding components with the frame, the frictional force between the transmission component and the frame becomes rolling friction. Thus, the frictional force between the transmission component and the frame during the movement of the transmission component along the frame can be reduced, and further, the energy consumption when the transmission component drives the loading mechanism to turn towards or away from the frame can be reduced, so as to achieve the purpose of reducing the usage cost.

[0027] 2. Since the loading and turning device can be turned, through the mutual cooperation of the vehicle body and the loading and turning device, automatic loading and unloading can be realized. Specifically, the cage is pushed into the loading mechanism that turns away from the frame. After the placement is completed, the power mechanism drives the loading mechanism to turn towards the frame again and drives the loading mechanism to be located on the vehicle body, thus completing the handling of the cage. Then, it is transferred or distributed through the logistics unmanned vehicle to improve the efficiency of logistics transportation and distribution. In addition, during the movement and turning of the loading mechanism, the loading and turning device can reduce its own energy consumption, thereby reducing the charging frequency of the logistics unmanned vehicle. Relatively, the distribution time of the logistics unmanned vehicle can be increased to further improve the efficiency of its logistics transportation and distribution. Description of the Drawings

[0040] Before explaining in detail any embodiment of the present application, it should be understood that the present application is not limited to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0041] In this application, the terms "comprise", "include", "have" or any other variants thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the presence of additional identical elements in the process, method, article or device comprising such element.

[0042] In this application, the term "and / or" describes the relationship between associated objects and indicates that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this application, the character " / " generally indicates that the associated objects before and after are in an "and / or" relationship.

[0043] In this application, the terms "connect", "combine", "couple", "mount" can be direct connection, combination, coupling or mounting, or can be indirect connection, combination, coupling or mounting. Among them, by way of example, direct connection means that two parts or components are connected together without the need to provide an intermediate member, and indirect connection means that two parts or components are respectively connected to at least one intermediate member, and these two parts or components are connected through the intermediate member. In addition, "connect" and "couple" are not limited to physical or mechanical connection or coupling, and can include electrical connection or coupling.

[0044] In this application, those of ordinary skill in the art will understand that relative terms used in connection with a quantity or condition (such as "about", "approximately", "substantially", etc.) are intended to include the stated value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances resulting from manufacturing, assembly, use in relation to a particular value, etc. Such terms should also be considered to disclose a range defined by the absolute values of two endpoints. Relative terms may refer to a plus or minus a certain percentage (such as 1%, 5%, 10% or more) of the indicated value. A numerical value without the use of a relative term should also be disclosed as a particular value having a tolerance. In addition, when expressing a relative angular positional relationship (such as substantially parallel, substantially perpendicular), "substantially" may refer to a plus or minus a certain number of degrees (such as 1 degree, 5 degrees, 10 degrees or more) based on the indicated angle.

[0045] In this application, those of ordinary skill in the art will understand that the functions performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the functions performed by a part can also be performed by one part, one component, or a combination of multiple parts.

For example, the lower side can include directly below, lower left, lower right, lower front, and lower back, etc.

[0047] Specific combination Figures 1 to 5 As shown specifically, the loading and flipping device provided in this embodiment is installed on an unmanned logistics vehicle and is used for loading a cage box, so as to achieve the technical purposes of saving energy consumption, reducing the use cost, and improving the distribution efficiency. Specifically: The loading and flipping device includes a frame 100, a power mechanism 200, a transmission mechanism, and a loading mechanism 400: Two guiding surfaces 121 are arranged on the frame 100 at intervals in the Y direction, and in the X direction, both guiding surfaces 121 extend obliquely away from the frame 100; The power mechanism 200 is arranged on the frame 100; The transmission mechanism includes a transmission component 310 and two groups of roller guiding components. The two groups of roller guiding components are arranged on the transmission component 310 at intervals in the Y direction and are both in rolling cooperation with the frame 100. The transmission component 310 is in transmission connection with the power mechanism 200; The loading mechanism 400 is rotatably connected to the connecting rod 311 in the transmission component 310; The power mechanism 200 can drive the loading mechanism 400 to move along the guiding surface 121 through the transmission component 310, so that the loading mechanism 400 flips in a direction closer to or away from the frame 100.

[0048] When the box loading mechanism 400 needs to load the cage box, in the X direction, the power mechanism 200 drives the loading mechanism 400 to move along the guiding surface 121. When the loading mechanism 400 moves to the highest point of the guiding surface 121, the loading mechanism 400 no longer moves in the X direction. However, at this time, the power mechanism 200 continues to operate and continuously drives the transmission mechanism to move towards the direction close to the loading mechanism 400. Under the action of the driving force of the power mechanism 200 and the limit of the loading mechanism 400, the support rod rotates continuously, so that the loading mechanism 400 flips in the direction away from the frame 100. At this time, the loading mechanism 400 stands upright to facilitate loading the cage box onto the loading mechanism 400. After the cage box is loaded onto the loading mechanism 400, the power mechanism 200 drives the transmission component 310 to move in the direction away from the X direction until the loading mechanism 400 flips towards the direction close to the frame 100 into the logistics autonomous vehicle. Then the power mechanism 200 continues to operate and drives the loading mechanism 400 to continuously move in the direction away from the X direction on the frame 100 until the loading mechanism 400 is completely located inside the side body 500 of the logistics autonomous vehicle, thus completing the loading of a cage box once.

[0049] Since both groups of roller guiding components are in rolling cooperation with the frame 100, when the power mechanism 200 operates and drives the loading mechanism 400 to move along the guiding surface 121 through the transmission component 310, causing the loading mechanism 400 to flip in the direction close to or away from the frame 100, the two groups of roller guiding components not only guide the transmission component 310 to move along the frame 100, but also during the movement of the transmission component 310 along the frame 100, due to the rolling cooperation of both groups of roller guiding components with the frame 100, the frictional force between the transmission component 310 and the frame 100 becomes rolling frictional force. Thus, the frictional force between the transmission component 310 and the frame 100 during the movement of the transmission component 310 along the frame 100 can be reduced, and further the energy consumption when the transmission component 310 drives the loading mechanism 400 to flip in the direction close to or away from the frame 100 can be reduced, so as to achieve the purpose of reducing the use cost.

[0050] Furthermore, the frame 100 includes two support shafts 110 arranged at intervals in the Y direction, and the two roller guiding components are correspondingly arranged on the transmission component 310 in one-to-one correspondence with the two support shafts 110; each roller guiding component includes a first guiding wheel 321, and the first guiding wheel 321 is rotatably connected to the transmission component 310 and is in rolling cooperation with the upper end surface of the corresponding support shaft 110.

[0051] Specifically, the two support shafts 110 are arranged in parallel at intervals along the Y direction and both extend along the X direction. The first guide wheel 321 is in rolling fit with the upper end surface of the corresponding support shaft 110. When the power mechanism 200 operates, the loading mechanism 400 moves along the X direction through the rolling fit between the first guide wheel 321 and the corresponding support shaft 110. In this process, it is possible to avoid the situation where the transmission assembly 310 slides on the frame 100, resulting in excessive frictional force between the two, thereby reducing the energy consumption during the movement of the transmission assembly 310 along the frame 100.

[0052] Furthermore, each roller guiding assembly includes a second guide wheel 322 and a first guide groove 323. The first guide groove 323 is arranged on the corresponding support shaft 110 and extends along the X direction. The second guide wheel 322 is rotatably connected to the transmission assembly 310 and is in rolling fit with the corresponding first guide groove 323.

[0053] Specifically, in this embodiment, the first guide grooves 323 are provided on the side walls of the two support shafts 110 that are close to each other. When the power mechanism 200 operates, through the rolling fit between the second guide wheel 322 and the corresponding first guide groove 323, on the one hand, it guides the transmission assembly 310 to always move along the established route in the X direction, thereby ensuring the running stability of the power mechanism 200 and the loading mechanism 400; on the other hand, it restricts the relative position of the power mechanism 200 and the frame 100 in the height direction to further improve the running stability of the power mechanism 200 and the loading mechanism 400, and avoid the situation where the first guide wheel 321 slips off the corresponding support shaft 110 in the height direction during the movement of the loading mechanism 400; on the third hand, it can avoid the generation of sliding friction between the second guide wheel 322 and the corresponding first guide groove 323, so as to further reduce the energy consumption during the operation of the whole machine.

[0054] Furthermore, the roller guiding assembly further includes a third guide wheel 324. The third guide wheel 324 is rotatably connected to the transmission assembly 310 and is in rolling fit with the corresponding support shaft 110. Along the Y direction, the second guide wheel 322 and the third guide wheel 324 are respectively arranged on both sides of the corresponding support shaft 110.

[0055] Specifically, in this embodiment, the second guide wheel 322 and the third guide wheel 324 are respectively arranged on both sides of the corresponding support shaft 110 to form a guiding and limiting space. When the power mechanism 200 operates, while guiding the transmission assembly 310 to move along the established route in the X direction, it avoids the situation where the first guide wheel 321 slips off the corresponding support shaft 110 in the Y direction.

[0056] In addition, in this embodiment, in order to further improve the running stability of the power mechanism and the loading mechanism 400, two second guide wheels 322 and two third guide wheels 324 are provided in each set of roller guide assemblies. The two second guide wheels 322 are both arranged inside the corresponding support shaft 110 and are spaced along the X direction. The two third guide wheels 324 are both arranged outside the corresponding support shaft 110 and are spaced along the X direction.

[0057] Preferably, the power mechanism 200 includes a driving member 210, a first chain 220, and a driven shaft 230. The driving member 210 is fixedly arranged on the frame 100. The driven shaft 230 is rotatably connected to the frame 100. Along the X direction, the driving member 210 and the driven shaft 230 are relatively spaced apart. The output shaft of the driving member 210 and the driven shaft 230 are connected by the first chain 220 for transmission, and the transmission assembly 310 is connected to the first chain 220 for transmission.

[0058] Specifically, an output sprocket (not shown in the figure) is fixedly arranged on the output shaft of the driving member 210, and a driven sprocket 231 is fixedly arranged on the driven shaft 230. The output sprocket and the driven sprocket 231 are both connected to the first chain 220 for transmission. When the driving member 210 is started, with the rotation of the output shaft, the output sprocket is driven to rotate, so as to drive the driven shaft 230 to rotate through the first chain 220 and the driven sprocket 231. During this process, since the transmission assembly 310 is connected to the first chain 220 for transmission, when the first chain 220 rotates, the transmission assembly 310 can be driven to move along the X direction through the first chain 220, so as to drive the loading mechanism 400 to move or turn over.

[0059] Further, the power mechanism 200 includes a reduction shaft 240 and a second chain 250. The reduction shaft 240 is rotatably connected to the frame 100 and is located between the driving member 210 and the driven shaft 230. The first chain 220 is connected between the output shaft and the reduction shaft 240 for transmission, and the second chain 250 is connected between the reduction shaft 240 and the driven shaft 230 for transmission.

[0060] Specifically, in order to avoid mechanical damage to the moving assembly, the frame 100, or the loading mechanism 400 when the driving member 210 drives the transmission assembly 310 to move in the X direction due to a relatively high moving speed, in this embodiment, a reduction shaft 240 is provided between the driving member 210 and the driven shaft 230. A first reduction sprocket 241 and a second reduction sprocket 242 are fixedly arranged at intervals along the Y direction on the reduction shaft 240, and the diameter of the second reduction sprocket 242 is larger than the diameter of the output sprocket; the first chain 220 is drivingly connected between the output sprocket and the second reduction sprocket 242, the second chain 250 is drivingly connected between the first reduction sprocket 241 and the driven sprocket 231, and the transmission assembly 310 is drivingly connected to the second chain 250, thereby achieving the technical purpose of reducing the moving speed of the power mechanism 200. In addition, in order to further improve the running stability of the power mechanism 200 and the loading mechanism 400, two first reduction sprockets 241 are arranged at intervals along the Y direction on the reduction shaft 240. Correspondingly, two driven sprockets 231 and two second chains 250 are provided.

[0061] In some other embodiments, the transmission connection between the output shaft, the reduction shaft 240, and the driven shaft 230 can be set as a belt drive in addition to the chain drive. Alternatively, without providing the output shaft, the reduction shaft 240, the first chain 220, and the second chain 250, the driving member 210 can be directly set as a push rod motor, and the push rod of the push rod motor is directly drivingly connected to the transmission assembly 310.

[0062] Preferably, the transmission assembly 310 includes a support plate 312 and a connecting member 313; two sets of roller guiding assemblies are arranged at intervals along the Y direction on the support plate 312. The support plate 312 is drivingly connected to the power mechanism 200 through the connecting member 313, and both ends of the connecting rod 311 are rotatably connected to the support plate 312 and the loading mechanism 400 respectively.

[0063] Specifically, the first guide wheel 321 is disposed on the support plate 312, and an avoidance area is provided on the support plate 312 corresponding to the first guide wheel 321. While ensuring the connection relationship between the support plate 312 and the bracket, the gap between the support plate 312 and the corresponding support shaft 110 is reduced, thereby further improving the running stability of the power mechanism 200. Two connecting members 313 are arranged at intervals along the Y direction on the support plate 312. The support plate 312 is connected to the corresponding second chain 250 through the connecting members 313 to achieve the transmission connection between the support plate 312 and the power mechanism 200. Connecting bearings 314 are provided at both ends of the connecting rod 311. One end of the connecting rod 311 is rotatably connected to the upper end surface of the support plate 312 through the corresponding connecting bearing 314, and the other end of the connecting rod 311 is rotatably connected to the loading mechanism 400 through the corresponding connecting bearing 314. Thus, in cooperation with the power mechanism 200, the loading mechanism 400 is flipped; in order to ensure the stability and safety during the flipping of the loading mechanism 400, two connecting rods 311 are arranged at intervals along the Y direction on the support plate 312.

[0064] Preferably, the frame 100 further includes two guide members 120 and two guide wheels 130. The two guide members 120 are correspondingly arranged on the two support shafts 110, and a reinforcing member 140 is provided on the guide member 120; the upper end surfaces of the two guide members 120 serve as guide surfaces 121, and the two guide wheels 130 and the two guide members 120 are correspondingly arranged on the loading mechanism 400 and are all in rolling cooperation with the corresponding guide surfaces 121. The two guide wheels are in rolling cooperation with the corresponding guide members 120, guiding the loading mechanism 400 to complete the flipping while reducing the friction between the guide member 120 and the loading mechanism 400. At the same time, since a reinforcing member 140 is provided on the guide member 120, the structural strength of the guide member 120 can be improved, thereby further improving the movement stability of the loading mechanism 400. The specific structures of the guide member 120 and the reinforcing member 140 are set according to actual needs and are not limited in this embodiment, as long as the technical effect that the upper end surface of the guide member 120 inclines away from the frame 100 along the X direction to form the guide surface 121 and the reinforcing member 140 can improve the structural strength of the guide member 120 can be achieved.

[0065] Preferably, the loading mechanism 400 includes a bottom bracket 410 and two baffles 420 . The two baffles 420 are spaced apart along the X direction on the upper end surface of the bottom bracket 410 . The connecting rod 311 is rotatably connected to the lower end surface of the bottom bracket 410 . The cross-sectional shape of the loading mechanism 400 along the Y direction is set to be in the shape of a Chinese character "凵". In this state, the body 500 of the unmanned logistics vehicle is set to include a bottom plate (not shown in the figure), a front plate (not shown in the figure) and two side plates (not shown in the figure), wherein the two side plates are relatively spaced apart on the bottom plate along the Y direction, and the two ends of the front plate are respectively connected to the front ends of the two side plates and fixedly connected, that is, in the height direction, the cross-sectional shape of the body 500 is set to be in the shape of a Chinese character "匸"; or the body 500 of the unmanned logistics vehicle is set to include a bottom plate and two side plates, and the two side plates are relatively spaced apart on the bottom plate along the Y direction, that is, in the height direction, the cross-sectional shape of the body 500 is set to be in the shape of a Chinese character "二", that is, at least the body 500 is ensured to have two relatively spaced apart side walls; thus, when the loading mechanism 400 is completely in the body 500 of the unmanned logistics vehicle, it cooperates with the two side walls of the body 500 along the Y direction to form a storage space. In this way, the loading effect of the cage box is guaranteed, and at the same time, the cage box is prevented from falling from the loading mechanism 400 after loading is completed and the logistics unmanned vehicle is driving.

[0066] In addition, limit bearings 232 are provided at both ends of the driven shaft 230, and two second guide grooves 150 are correspondingly provided on the bottom bracket 410. The two limit bearings 232 roll in cooperation with the two second guide grooves 150 in a one-to-one correspondence, guiding the running path of the bottom bracket 410 while limiting the relative position of the bottom bracket 410 to avoid the bottom bracket 410 being completely separated from the frame 100.

[0067] In some other embodiments, the cross-sectional shape of the loading mechanism 400 along the Y direction is set to an "L" shape. In this state, the cross-sectional shape of the vehicle body 500 in the height direction can be set to a "匸" shape. Alternatively, four baffles 420 are provided, two of which are spaced apart along the X direction on the upper end surface of the bottom bracket 410, and the other two baffles 420 are spaced apart along the Y direction on the upper end surface of the bottom bracket 410. In this state, the vehicle body 500 of the unmanned logistics vehicle can be set to a flat plate shape.

[0068] The logistics unmanned vehicle includes a vehicle body 500 and a loading and turning device, and the loading and turning device is arranged on the vehicle body 500.

[0069] Since the loading and flipping device can be flipped, through the cooperation of the vehicle body 500 and the loading and flipping device, automatic loading and unloading can be achieved. Specifically, the cage is pushed into the loading mechanism 400 that flips in the direction away from the frame 100. After the placement is completed, the power mechanism 200 drives the loading mechanism 400 to flip again in the direction close to the frame 100, and drives the loading mechanism 400 to be located on the vehicle body 500, thereby completing the handling of the cage. Then, it is transferred or distributed through the logistics autonomous vehicle to improve the efficiency of logistics transportation and distribution. In addition, during the movement and flipping of the loading mechanism 400, the loading and flipping device can reduce its own energy consumption, thereby reducing the charging frequency of the logistics autonomous vehicle. Relatively, the distribution time of the logistics autonomous vehicle can be increased to further improve the efficiency of its logistics transportation and distribution.
