[0002] With the development of science and technology, unmanned equipment is applied in various fields. In order to make the distribution intelligent and efficient, logistics companies are trying to provide unmanned express delivery services. During the unmanned delivery process, the package departs from the unmanned warehouse, is transported to the corresponding distribution center by an unmanned logistics vehicle, and finally delivered to the customer by an unmanned delivery vehicle. In the existing unmanned logistics vehicles, the transfer box is fixedly installed on the vehicle body. After the unmanned logistics vehicle transports the package to the corresponding distribution center, it will return empty. The transfer box is relatively heavy, so the existing unmanned logistics vehicle will generate a lot of fuel consumption when running empty, resulting in an increase in the transportation cost of package delivery.

[0003] Therefore, there is an urgent need for a flipping mechanism and an unmanned logistics vehicle to solve the above technical problems. Utility Model Content

[0009] The support assembly is arranged at one end of the chassis platform away from the driving assembly, and the support assembly is used to play a supporting role when the transfer box is installed on the chassis platform.

[0010] As a preferred technical solution of the flipping mechanism, the driving assembly includes a driving member, a driving wheel, a first transmission unit, a transmission connecting member, and a second transmission unit. The first transmission unit is in transmission connection with the driving wheel. The second transmission unit is located on one side of the fixed frame along the second direction.

[0013] As a preferred technical solution of the support assembly, the support assembly includes a support base, a connecting shaft, and a guiding wheel. The support base is fixedly connected to the chassis platform. The connecting shaft is fixed to the support base. The guiding wheel is connected to the connecting shaft.

The setting of the flipping mechanism enables the transfer box to be selectively installed onto the chassis platform. Thus, when the unmanned logistics vehicle is transporting without load, the staff can remove the transfer box through the flipping mechanism, reducing the overall weight during the no-load transportation of the unmanned logistics vehicle, lowering the fuel consumption during the no-load transportation of the unmanned logistics vehicle, and thereby reducing the package transportation cost. On the contrary, when the unmanned logistics vehicle needs to transport packages, the staff can also install the transfer box onto the chassis platform through the flipping mechanism to ensure the normal transportation of the packages.

[0021] The unmanned logistics vehicle provided by the present utility model can choose to disassemble the transfer box when it is unloaded and install the transfer box when it needs to transport packages, with high flexibility in use. At the same time, when running without load, the overall weight is relatively light, which can avoid the generation of excessive large amounts of fuel consumption and can effectively reduce the distribution and transportation cost of packages.

[0040] Embodiment 1

[0041] As Figures 1 to 7 shown, this embodiment provides a flipping mechanism, which is arranged on the chassis platform 100 of the unmanned logistics vehicle. The flipping mechanism can selectively install the transfer box 200 on the chassis platform 100. According to different loading situations of the unmanned logistics vehicle, the unmanned logistics vehicle can selectively assemble the transfer box 200. Among them, the first direction is along the X direction parallel to the chassis platform 100, and the second direction is along the Y direction parallel to the chassis platform 100.

[0042] As Figure 1 , Figure 5 and Figure 7 shown, the flipping mechanism includes a driving component 1, a bearing component 2, a fixing frame 3, a connecting rod 4 and a connecting arm 5. Among them, the driving component 1 is connected to the bearing component 2, and the fixing frame 3 is arranged at a distance from the driving component 1. The driving component 1 can drive the bearing component 2 to reciprocate along the first direction between the driving component 1 and the fixing frame 3. One end of the connecting rod 4 is connected to the bearing component 2 and can move together with the bearing component 2. One end of the connecting arm 5 is rotatably connected to the fixing frame 3. A connecting part is provided at one end of the connecting arm 5 close to the connection with the fixing frame 3. The other end of the connecting rod 4 is connected to the connecting part. The connecting arm 5 has a flipping state and an initial state. Since one end of the connecting rod 4 is connected to the bearing component 2 and the other end is connected to the connecting part, and at the same time the connecting arm 5 is rotatably connected to the fixing frame 3, when the driving component 1 operates, the connecting rod 4 moves along the first direction and towards the fixing frame 3 together with the bearing component 2. The connecting arm 5 rotates relative to the fixing frame 3 and the connecting rod 4 at the same time, and the connecting rod 4 rotates relative to the bearing component 2, so that the connecting arm 5 can flip relative to the chassis platform 100, and the flipping angle is an obtuse angle. At this time, the connecting arm 5 is in the flipping state.

[0043] As Figure 1 and Figure 6As shown in the figure, a hook member 6 is provided at the other end of the connecting arm 5. The hook member 6 is configured to be connected to the transfer box 200. A connecting member is provided on the transfer box 200. When the connecting arm 5 rotates relative to the chassis platform 100, the hook member 6 can hook the connecting member. Subsequently, the driving assembly 1 moves in the reverse direction, and the bearing member 2 drives the connecting rod 4 to move towards the driving assembly 1. The connecting arm 5 rotates in the reverse direction and gradually returns to the initial state. Thus, when the bearing member 2 drives the connecting rod 4 to move towards the fixing frame 3, the connecting arm 5 is adjusted from the initial state to the flipped state to hook the connecting member on the transfer box 200. Subsequently, the running direction of the driving assembly 1 is adjusted so that the bearing member 2 drives the connecting rod 4 to move towards the driving assembly 1, and the connecting arm 5 is adjusted from the flipped state to the initial state, and the installation of the transfer box 200 is completed. To ensure that the transfer box 200 can move stably when the connecting arm 5 installs the transfer box 200 onto the chassis platform 100, the flipping mechanism further includes a support assembly 7. The support assembly 7 is provided at one end of the chassis platform 100 away from the driving assembly 1 for supporting the transfer box 200 during the movement of the transfer box 200.

[0044] For the flipping mechanism provided in this embodiment, by controlling the moving direction of the connecting rod 4 through the driving assembly 1, the state of the connecting arm 5 relative to the chassis platform 100 can be adjusted. When the driving assembly 1 drives the connecting rod 4 to move along the first direction and towards the fixing frame 3 through the bearing member 2, the connecting arm 5 rotates relative to the chassis platform 100, and the hook member 6 can hook the transfer box 200. When the driving assembly 1 runs in the reverse direction, causing the bearing member 2 to drive the connecting rod 4 to move towards the driving assembly 1, the connecting arm 5 rotates in the reverse direction and gradually lowers, and the transfer box 200 is installed on the chassis platform 100. The setting of the flipping mechanism can selectively install the transfer box 200 on the chassis platform 100. Thus, when the unmanned logistics vehicle is transporting without load, the staff can remove the transfer box 200 through the flipping mechanism, reducing the overall weight during the no-load transportation of the unmanned logistics vehicle, reducing the fuel consumption of the unmanned logistics vehicle during no-load transportation, and thus reducing the package transportation cost. On the contrary, when the unmanned logistics vehicle needs to transport packages, the staff can also install the transfer box 200 on the chassis platform 100 through the flipping mechanism to ensure the normal transportation of the packages.

[0045] In this embodiment, the connecting member on the transfer box 200 can be a connecting handle. When the flipping mechanism needs to be connected to the transfer box 200, the hook member 6 is connected to the connecting handle. Of course, the connecting member on the transfer box 200 can also be a connecting ring, and the hook member 6 is connected to the connecting ring. The structure of the connecting member is not specifically limited herein.

[0046] In this embodiment, as Figures 1 to 3As shown in the figure, the driving assembly 1 includes a driving member 11, a driving wheel 12, a first transmission unit 14, a transmission connecting member 13 and a second transmission unit. The driving member 11 is drivingly connected to the driving wheel 12 for rotating the driving wheel 12. The driving member 11 can rotate forward and backward to adjust the forward and backward rotation of the driving wheel 12. The first transmission unit 14 is drivingly connected to the driving wheel 12. The second transmission unit is located on one side of the fixing frame 3 along the second direction. The transmission connecting member 13 drivingly connects the first transmission unit 14 and the second transmission unit. The bearing member 2 is connected to the transmission connecting member 13. Specifically, when the driving member 11 rotates the driving wheel 12 forward, the transmission connecting member 13 drives the bearing member 2 to move toward the fixing frame 3 along the first direction, and the connecting arm 5 is adjusted from the initial state to the flipped state. When the driving member 11 rotates the driving wheel 12 backward, the transmission connecting member 13 drives the bearing member 2 to move toward the driving assembly 1 along the first direction, and the connecting arm 5 is adjusted from the flipped state to the initial state.

[0047] In this embodiment, the driving member 11 is a rotating motor, and its output end is connected to the driving wheel 12. The rotating motor can be a synchronous motor, an asynchronous motor, a servo motor, or a permanent magnet motor. The type of the rotating motor is not limited herein.

[0048] Exemplarily, the first transmission unit 14 includes a first base 141, a rotating shaft 142, a main transmission wheel 143, a transmission member 144 and a first runner 145. The first base 141 is fixed to the chassis platform 100. The rotating shaft 142 passes through the first base 141 and is rotatably connected thereto. The main transmission wheel 143 passes through the rotating shaft 142 and is fixedly connected thereto. The first runner 145 is fixedly connected to the rotating shaft 142 and is spaced from the main transmission wheel 143. The transmission member 144 is drivingly connected between the driving wheel 12 and the main transmission wheel 143. Controlling the steering of the driving wheel 12 can control the steering of the main transmission wheel 143, and further control the steering of the first runner 145. The second transmission unit includes a second base 151 and a second runner. The second base 151 is placed on one side of the fixing frame 3 along the second direction and is opposite to the first runner 145. The second runner is rotatably connected to the second base 151. The transmission connecting member 13 is connected between the first runner 145 and the second runner. In this way, when the driving wheel 12 rotates forward, the transmission connecting member 13 drives the connecting rod 4 to move toward the fixing frame 3 through the bearing member 2, and the connecting arm 5 rotates to the flipped state. When the driving wheel 12 rotates backward, the transmission connecting member 13 drives the connecting rod 4 to move toward the driving assembly 1 through the bearing member 2, and the connecting arm 5 rotates back to the initial state. At the same time, by placing the second transmission unit on one side of the fixing frame 3 along the second direction, the bearing member 2 can move between the fixing frame 3 and the driving assembly 1.

[0049] Preferably, two first runners 145, two second bases 151, two second runners and two transmission connectors 13 can be provided. The two first runners 145 are arranged at both ends of the rotating shaft 142. The two second bases 151 are respectively placed on both sides of the fixing frame 3 and are opposite to the two first runners 145 respectively. The two second runners are correspondingly connected to the two second bases 151. The two transmission connectors 13 are respectively connected to two groups of first runners 145 and second runners. The carrier 2 is connected between the two transmission connectors 13, which can improve the stability of the driving assembly 1 driving the carrier 2 to move, and further improve the stability of the turning process of the connecting arm 5.

[0050] Wherein, when the driving wheel 12, the main transmission wheel 143, the first runner 145 and the second runner are gears, the transmission member 144 and the transmission connector 13 are correspondingly chains. When the driving wheel 12, the main transmission wheel 143, the first runner 145 and the second runner are circular wheels, the transmission member 144 and the transmission connector 13 are correspondingly conveyor belts.

[0051] In other embodiments, the driving assembly 1 can also be a telescopic air cylinder, and the carrier 2 is connected to the output end of the telescopic air cylinder; the driving assembly 1 can also be a telescopic rod, and the carrier 2 is connected to the output end of the telescopic rod.

[0052] In this embodiment, as Figure 1 、 Figure 2 and Figure 4 shown, the turning mechanism further includes a guide rail 8. The guide rail 8 is laid along the first direction. A guiding assembly 9 is provided on the carrier 2. The guiding assembly 9 includes a first guiding member 91 and a second guiding member 92. Specifically, the first guiding member 91 and the second guiding member 92 are respectively placed on both sides of the guide rail 8 and are both in contact with the guide rail 8. When the driving assembly 1 drives the carrier 2 to move along the first direction, the guiding assembly 9 can play a certain guiding role and further improve the stability of the carrier 2 during the moving process.

[0053] Exemplarily, the guide rail 8 has a guide groove facing the carrier 2. The first guiding member 91 includes a connecting bracket and a first guide wheel connected together. The second guiding member 92 includes a second guide wheel. The connecting bracket is fixedly connected to the carrier 2. The first guide wheel is placed in the guide groove. The connecting bracket is in contact with the side of the guide groove. The circumferential surface of the second guide wheel is in contact with the bottom surface of the guide groove. In this way, the guiding assembly 9 can not only guide the movement of the carrier 2, but also the first guide wheel and the second guide wheel can rotate when the carrier 2 moves, reducing the friction between the guiding assembly 9 and the guide rail 8 and further improving the smoothness of the carrier 2 during the moving process.

[0054] Exemplarily, as Figure 1As shown in the figure, the support assembly 7 includes a support base 71, a connecting shaft 72, and a guide wheel 73. The support base is fixedly connected to the chassis platform 100. The connecting shaft 72 is fixed to the support base 71, and the guide wheel 73 is connected to the connecting shaft 72. When the connecting arm 5 drives the transfer box 200 to be placed on the chassis platform 100, the circumferential surface of the guide wheel 73 abuts against the transfer box 200. That is, after the connecting arm 5 is connected to the transfer box 200, during the process of the connecting arm 5 being adjusted from the flipped state to the initial state, one side of the transfer box 200 abuts against the guide wheel 73. As the transfer box 200 moves, the guide wheel 73 rotates, improving the smoothness of the transfer process of the transfer box 200. Preferably, two guide wheels 73 are provided on the support assembly 7, and the two guide wheels 73 are respectively arranged at both ends of the connecting shaft 72. In this way, the two guide wheels 73 support two points of the transfer box 200, further improving the stability and smoothness of the transfer process of the transfer box 200.

[0055] In this embodiment, the cross-sectional shape of the connecting arm 5 is L-shaped. Compared with a straight shape, when the L-shaped connecting arm 5 is in the flipped state, the hook member 6 is at a lower height relative to the ground, which is more convenient for the installation of the transfer box 200 and the hook member 6, making the design of the connecting arm 5 more reasonable.

[0056] Exemplarily, as Figure 6 shown in the figure, the hook member 6 includes a fixed seat 61 and a connecting hook 62. The fixed seat 61 is fixedly connected to the connecting arm 5, and the connecting hook 62 is fixed to the fixed seat 61. The connecting hook 62 includes a hook portion 621 and a blocking portion 622. The blocking portion 622 is located beside the hook portion 621. The hook portion 621 is provided to hook the connecting member on the transfer box 200, and the blocking portion 622 is provided to prevent the transfer box 200 from detaching from the hook member 6 during the process of the tipping mechanism transporting the transfer box 200, ensuring the movement range of the connecting member within the connecting hook 62, and further improving the safety of the transfer box 200 during the installation process onto the chassis platform 100. Preferably, for the convenience of processing the hook member 6 and to ensure the strength of the hook member 6, the fixed seat 61 and the connecting hook 62 are an integral structure.

[0057] In this embodiment, the tipping mechanism further includes a support block. The support block is arranged close to the driving assembly 1, and the connecting arm 5 can selectively abut against the support block. When the connecting arm 5 is in the initial state, the connecting arm 5 abuts against the support block, and the support block can support the connecting arm 5, ensuring the stability of the connecting arm 5 in the initial state, and further ensuring the stability of the transfer box 200 placed on the chassis platform 100.

[0058] Embodiment Two

[0059] As Figure 7As shown in , this embodiment provides an unmanned logistics vehicle, including the flipping mechanism in embodiment one, and the unmanned vehicle also includes a transfer box 200. The flipping mechanism is fixedly mounted on a support frame, and the flipping mechanism can selectively place the transfer box 200 on a chassis platform 100.

[0060] The unmanned logistics vehicle provided in this embodiment can choose to remove the transfer box 200 when it is empty, and install the transfer box 200 when it is needed to transport packages. It has high flexibility in use. At the same time, when it is running empty, the overall weight is relatively light, which can avoid the generation of unnecessary fuel consumption and effectively reduce the delivery and transportation costs of packages.

[0061] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
