[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The embodiment of the present invention provides a vehicle that can load and unload containers through a loading and unloading device installed on the vehicle body, thereby solving the problem that existing vehicles can only be used to transport containers but cannot load and unload containers. The above-mentioned vehicle mentioned in the embodiment of the present invention can be an ordinary vehicle such as a car, an electric car, a new energy vehicle, etc. that requires a driver to drive, or a rail vehicle that transports containers, or various unmanned vehicles that transport containers.

[0035] Among them, please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 A vehicle 1 is provided in one embodiment of the present invention, and the vehicle 1 includes a vehicle body 11 for placing containers, and the vehicle 1 also includes a loading and unloading device 12 installed on the vehicle body 11, and a control device 13 for controlling the operation of the loading and unloading device 12; the loading and unloading device 12 is used to unload the container placed on the vehicle body 11 or load the container onto the vehicle body 11 under the control of the control device 13.

[0036] like Figure 1As shown in the structure, the vehicle 1 can be a truck, including a body 11 for carrying containers, a plurality of wheels, a front end with a cab, a loading and unloading device 12 installed at the front and rear ends of the body 11, and a control device 13 for controlling the action of the loading and unloading device 12. The loading and unloading device 12 can include a first loading and unloading unit 121 installed at the front end of the body 11 and a second loading and unloading unit 122 installed at the rear end of the body 11 and opposite to the first loading and unloading unit 121. When the vehicle 1 transports or transships the container, first, the vehicle 1 is parked near the container to be transported, and the control device 13 controls the loading and unloading device 12 to operate after receiving the loading control instruction, and the loading and unloading device 12 loads the container from the ground or the warehouse onto the body 11; secondly, after the container is transported to the designated location by the vehicle 1, the control device 13 controls the loading and unloading device 12 to operate after receiving the unloading control instruction, and the container placed on the body 11 is unloaded through the loading and unloading device 12; thereby completing the container transportation work.

[0037] In some examples, a physical switch or an electronic switch that is in communication connection with the control device 13 may be provided on the vehicle 1, and the driver may send a loading control instruction or an unloading control instruction to the control device 13 by operating the physical switch or the electronic switch. In other examples, a user interaction interface may be provided on the vehicle 1, and the driver may send a loading control instruction and an unloading control instruction to the control device 13 by operating on the user interaction interface. In some other examples, a remote control device that can be used to control the control device 13 is provided, and the driver may send a loading control instruction and an unloading control instruction to the control device 13 by pressing a button on the remote control device.

[0038] Since the vehicle 1 is provided with a loading and unloading device 12 on the vehicle body 11 and a control device 13 for controlling the movement of the loading and unloading device 12 to load and unload containers, when the vehicle 1 is used to transport containers, the transported containers can be loaded and unloaded through the loading and unloading device 12 configured by the vehicle 1, and there is no need to use additional lifting equipment to lift the containers. This not only facilitates loading and unloading, but also reduces the cost of using the lifting equipment, so that the vehicle 1 can not only transport containers, but also load and unload containers, making the vehicle 1 multifunctional.

[0039] Therefore, the above-mentioned vehicle 1 can solve the problem that the existing vehicle 1 can only be used to transport containers but cannot load and unload containers.

[0040] In a specific implementation manner, Figure 1 , Figure 2 as well as Figure 3 As shown in the structure, the loading and unloading device 12 may include a first loading and unloading unit 121 and a second loading and unloading unit 122 which are arranged opposite to each other; Figure 1As shown in the structure,

[0041] The first loading and unloading unit 121 and the second loading and unloading unit 122 are relatively arranged along the length direction of the vehicle body 11. In actual use, the first loading and unloading unit 121 and the second loading and unloading unit 122 can also be relatively arranged along the width direction of the vehicle body 11. Alternatively, in order to improve the stability and lifting quality of the loading and unloading device 12, multiple loading and unloading units can also be relatively arranged.

[0042] like Figure 1 As shown in the structure, the first loading and unloading unit 121 includes a first telescopic arm 1211 installed on the vehicle body 11, a second telescopic arm 1212 installed on the first telescopic arm 1211, and a first container lock 1213 installed on the second telescopic arm 1212; the first telescopic arm 1211 can be telescopic along the width direction of the vehicle body 11, so the container can be displaced in the width direction of the vehicle body 11 by the telescopic movement of the first telescopic arm 1211; the second telescopic arm 1212 can be telescopic along the vertical direction, so the container can be lifted or lowered in the vertical direction by the telescopic movement of the second telescopic arm 1212 to achieve loading and unloading of the container; the first container lock 1213 is used to detachably fix the container. When the container needs to be operated by the first loading and unloading unit 121, the first container lock 1213 can be fixed to the container, so that the container and the first loading and unloading unit 121 form an integrated structure, and then the movement of the container is completed by the telescopic movement of the first telescopic arm 1211 and the second telescopic arm 1212.

[0043] like Figure 1 and Figure 3 As shown in the structure, the second loading and unloading unit 122 includes a third telescopic arm 1221 installed on the vehicle body 11, a fourth telescopic arm 1222 installed on the third telescopic arm 1221, and a second container lock 1223 installed on the fourth telescopic arm 1222; the third telescopic arm 1221 can be telescopic in the width direction of the vehicle body 11, so the container can be moved in the width direction of the vehicle body 11 through the telescopic movement of the first telescopic arm 1211 and the third telescopic arm 1221; the fourth telescopic arm 1222 can be telescopic in the vertical direction, and the container can be moved in the width direction of the vehicle body 11 through the telescopic movement of the first telescopic arm 1211 and the third telescopic arm 1221; The container can be lifted or lowered in the vertical direction by telescoping the second telescopic arm 1212 and the fourth telescopic arm 1222 to realize loading and unloading of the container; the second container lock 1223 is used to detachably fix the container. When the container needs to be loaded and unloaded, the first container lock 1213 and the second container lock 1223 can be used to fix the container, so that the container and the first loading and unloading unit 121 and the second loading and unloading unit 122 form an integrated structure, and then the loading and unloading of the container can be completed by telescoping the telescopic arms.

[0044] The vehicle 1 can move the container in the horizontal direction through the telescopic movement of the first telescopic arm 1211 and the third telescopic arm 1221, and can move the container in the vertical direction through the telescopic movement of the second telescopic arm 1212 and the fourth telescopic arm 1222. At the same time, the container is fixed to the loading and unloading device 12 through the first container lock 1213 and the second container lock 1223, so as to realize the loading and unloading of the container through the loading and unloading device 12; since the container can be moved in the horizontal direction and the vertical direction respectively or simultaneously through each telescopic arm, the container can be translated during the handling process, so the goods in the container can be protected from being squeezed, and then the goods in the container can be protected to prevent economic losses caused by damage to the goods.

[0045] In order to be able to adjust the fixed position of the container lock on the container or to make the loading and unloading device 12 suitable for containers of different sizes, such as Figure 1 and Figure 2 As shown in the structure, the first loading and unloading unit 121 may also include a fifth telescopic arm 1214 installed on a side surface of the second telescopic arm 1212 facing the second loading and unloading unit 122 and capable of being telescopic along the length direction of the vehicle body 11, and the first container lock 1213 is installed on the fifth telescopic arm 1214; the position of the first container lock 1213 can be adjusted by telescoping the fifth telescopic arm 1214 to adjust the locking position of the first container lock 1213 on the container surface, and at the same time, the distance between the first container lock 1213 and the second container lock 1223 can be reduced, so that it can be fixed on the surface of containers of different sizes and containers of different sizes can be loaded and unloaded;

[0046] The second loading and unloading unit 122 may further include a sixth telescopic arm 1224 installed on a side surface of the fourth telescopic arm 1222 facing the first loading and unloading unit 121 and capable of being telescoped along the length direction of the vehicle body 11, and the second container lock 1223 is installed on the sixth telescopic arm 1224; since the sixth telescopic arm 1224 can be telescoped along the length direction of the vehicle body 11, the locking position of the second container lock 1223 on the container surface can be adjusted by the telescopic movement of the sixth telescopic arm 1224, and at the same time, the distance between the first container lock 1213 and the second container lock 1223 can be reduced, so that it can be fixed on the surfaces of containers of different sizes and containers of different sizes can be loaded and unloaded.

[0047] Since the first loading and unloading unit 121 includes the fifth telescopic arm 1214 installed on the second telescopic arm 1212, and the second loading and unloading unit 122 includes the sixth telescopic arm 1224 installed on the fourth telescopic arm 1222, the distance between the first container lock 1213 and the second container lock 1223 can be adjusted by telescoping the fifth telescopic arm 1214 and the sixth telescopic arm 1224, thereby adjusting the locking positions of the first container lock 1213 and the second container lock 1223 on the container surface, that is, the loading and unloading device 12 can be enabled to load and unload containers of different sizes by adjusting the locking positions, thereby expanding the use scope of the vehicle 1 and the loading and unloading device 12.

[0048] Specifically, the above-mentioned vehicle 1 may also include a hydraulic system 14 or a pneumatic system for driving the first telescopic arm 1211, the second telescopic arm 1212, the third telescopic arm 1221, the fourth telescopic arm 1222, the fifth telescopic arm 1214 and the sixth telescopic arm 1224 to extend and retract; the control device 13 is connected to the hydraulic system 14 or the pneumatic system signal, and is used to control the action of the hydraulic system 14 or the pneumatic system.

[0049] The vehicle 1 can drive the telescopic arms in the loading and unloading device 12 through the hydraulic system 14 or the pneumatic system to realize the telescopic movement of each telescopic arm, thereby realizing the loading and unloading of the container by the loading and unloading device 12. When the vehicle 1 itself is provided with a hydraulic system 14 or a pneumatic system, the hydraulic system 14 or the pneumatic system configured by the vehicle 1 itself can be directly used, and in this case, the structure of the vehicle 1 can also be simplified.

[0050] Specifically, the hydraulic system 14 may include a hydraulic pump, a hydraulic cylinder, a hydraulic pipeline connecting the hydraulic pump and the hydraulic cylinder, and a hydraulic valve arranged on the hydraulic pipeline; the control device 13 is signal-connected with the hydraulic pump and the hydraulic valve, so as to control each hydraulic valve through the control device 13, realize on-off control of the corresponding hydraulic pipeline, and further control the on-off of the hydraulic pump and the corresponding hydraulic cylinder.

[0051] In order to achieve precise control of each telescopic arm, the hydraulic cylinders include a first hydraulic cylinder provided at the first telescopic arm 1211, a second hydraulic cylinder provided at the second telescopic arm 1212, a third hydraulic cylinder provided at the third telescopic arm 1221, a fourth hydraulic cylinder provided at the fourth telescopic arm 1222, a fifth hydraulic cylinder provided at the fifth telescopic arm 1214, and a sixth hydraulic cylinder provided at the sixth telescopic arm 1224;

[0052] The hydraulic valves include a first hydraulic valve disposed between the hydraulic pump and the first hydraulic cylinder, a second hydraulic valve disposed between the hydraulic pump and the second hydraulic cylinder, a third hydraulic valve disposed between the hydraulic pump and the third hydraulic cylinder, a fourth hydraulic valve disposed between the hydraulic pump and the fourth hydraulic cylinder, a fifth hydraulic valve disposed between the hydraulic pump and the fifth hydraulic cylinder, and a sixth hydraulic valve disposed between the hydraulic pump and the sixth hydraulic cylinder;

[0053] The control device 13 is signal-connected to the first hydraulic valve, the second hydraulic valve, the third hydraulic valve, the fourth hydraulic valve, the fifth hydraulic valve and the sixth hydraulic valve.

[0054] Since each telescopic arm is provided with a corresponding hydraulic cylinder, and a hydraulic valve for controlling the opening and closing of the hydraulic pipeline is provided on the hydraulic pipeline between each hydraulic cylinder and the hydraulic pump, the telescopic control of each telescopic arm is realized by controlling each hydraulic valve through the control device 13, so as to realize the loading and unloading of the container by the loading and unloading device 12. Since each telescopic arm is provided with a corresponding hydraulic cylinder and hydraulic valve, each telescopic arm can be accurately controlled, and the loading and unloading accuracy and reliability of the loading and unloading device 12 of the vehicle 1 can be improved.

[0055] In order to improve the stability and reliability of the loading and unloading device 12 when loading and unloading containers, Figure 1 and Figure 2 As shown in the structure, the first telescopic arm 1211 is provided with a first support column 1215 at one end where the second telescopic arm 1212 is provided, and the first support column 1215 is used to support the cantilever end of the first telescopic arm 1211 when loading and unloading containers; the third telescopic arm 1221 is provided with a second support column 1225 at one end where the fourth telescopic arm 1222 is provided, and the second support column 1225 is used to support the cantilever end of the third telescopic arm 1221 when loading and unloading containers. Figure 1 and Figure 2 As shown in the structure, the first support column 1215 and the second support column 1225 can both be support columns with adjustable heights, and the first support column 1215 and the second support column 1225 can both be hydraulic rods or pneumatic rods.

[0056] Since a first support column 1215 is provided at one end of the first telescopic arm 1211 and a second support column 1225 is provided at one end of the third telescopic arm 1221, when the loading and unloading device 12 is used to load and unload the container, the cantilever end of the first telescopic arm 1211 can be supported by the first support column 1215 to form a fulcrum, and the cantilever end of the third telescopic arm 1221 can be supported by the second support column 1225 to form a fulcrum, so that both ends of the first telescopic arm 1211 and the third telescopic arm 1221 are supported by the fulcrum, thereby improving the structural strength of the first loading and unloading unit 121 and the second loading and unloading unit 122, thereby improving the stability and reliability of the vehicle 1.

[0057] On the basis of the above-mentioned various embodiments, in order to facilitate the telescopic movement of the first telescopic arm 1211 and the second telescopic arm 1221, a first roller 1216 capable of rolling is provided at the bottom end of the first support column 1215, and a second roller 1226 capable of rolling is provided at the bottom end of the second support column 1225.

[0058] Since a first roller 1216 is provided at the lower end of the first support column 1215 and a second roller 1226 is provided at the bottom end of the second support column 1225, during the telescopic movement of the first telescopic arm 1211 and the second telescopic arm 1221, the first telescopic arm 1211 and the second telescopic arm 1221 can roll with the support of the corresponding support columns, thereby improving the smoothness of the movement of the first telescopic arm 1211 and the second telescopic arm 1221 and the stability of the entire vehicle 1.

[0059] At the same time, the first roller 1216 and the second roller 1226 can also be replaced by a ball or steel ball arranged at the bottom end of the support column. In order to improve working reliability, a braking mechanism can also be configured for the first roller 1216 and the second roller 1226 to further improve the stability of the vehicle 1.

[0060] The working process of the above vehicle 1 when loading and unloading containers is as follows:

[0061] 1. Load the container onto vehicle 1

[0062] After receiving the loading control instruction, the control device 13 controls the loading and unloading device 12 to perform the following actions to load the container onto the vehicle 1:

[0063] First, the first telescopic arm 1211 and the third telescopic arm 1221 are controlled to extend horizontally, so that the first movable arm of the first telescopic arm 1211 extends outward relative to the first fixed arm, and the third movable arm 12212 of the third telescopic arm 1221 extends outward relative to the third fixed arm 12211 .

[0064] Secondly, the second telescopic arm 1212 and the fourth telescopic arm 1222 are controlled to extend upward, so that the second movable arm of the second telescopic arm 1212 extends upward relative to the second fixed arm, and the fourth movable arm 12222 of the fourth telescopic arm 1222 extends upward relative to the fourth fixed arm 12221, in order to make the first container lock 1213 and the second container lock 1223 reach the top of the container.

[0065] Then, the second telescopic arm 1212 and the fourth telescopic arm 1222 are controlled to retract downward, so that the first container lock 1213 and the second container lock 1223 are fixed on the top surface of the container, and the first container lock 1213 and the second container lock 1223 are controlled to be locked, so that the container is fixed together with the loading and unloading device 12. In addition, in order to adjust the position of the first container lock 1213 and the second container lock 1223, the control device 13 controls the fifth telescopic arm 1214 and the sixth telescopic arm 1224 to adjust the position of the first container lock 1213 and the second container lock 1223 along the front and rear of the vehicle body 11. In order to improve stability, the sixth telescopic arm 1224 may include a sixth fixed arm 12241 and a sixth movable arm 12242, and the sixth telescopic arm 1224 may also include a sixth cross arm 12243, and a plurality of second container locks 1223 may be provided through the sixth cross arm 12242 to achieve locking reliability between the loading and unloading device 12 and the container.

[0066] Finally, the control device 13 controls the second telescopic arm 1212 and the fourth telescopic arm 1222 to extend upward so that the bottom surface of the container is higher than the top surface of the vehicle body 11, and then controls the first telescopic arm 1211 and the third telescopic arm 1221 to retract through the control device 13 to make the container translate toward the vehicle body 11. When the container is exactly located on the upper part of the vehicle body 11, the second telescopic arm 1212 and the fourth telescopic arm 1222 are controlled to retract to place the container on the vehicle body 11.

[0067] 2. Unload the container from vehicle 1

[0068] When receiving the unloading instruction, the control device 13 controls the loading and unloading device 12 to operate to unload the container from the vehicle 1:

[0069] First, control the second telescopic arm 1212 and the fourth telescopic arm 1222 to extend upward, so that the second movable arm of the second telescopic arm 1212 extends upward relative to the second fixed arm, and the fourth movable arm 12222 of the fourth telescopic arm 1222 extends upward relative to the fourth fixed arm 12221, so as to move the container upward and detach from the vehicle body 11.

[0070] Then, the first telescopic arm 1211 and the third telescopic arm 1221 are controlled to extend laterally, so that the first movable arm of the first telescopic arm 1211 extends outward relative to the first fixed arm, and the third movable arm 12212 of the third telescopic arm 1221 extends outward relative to the third fixed arm 12211, so as to translate the container toward the outside of the vehicle body 11. When the container reaches the designated unloading position, the second telescopic arm 1212 and the fourth telescopic arm 1222 are controlled to retract downward to place the container at the designated position.

[0071] Finally, the control device 13 controls the first container lock 1213 and the second container lock 1223 to unlock, controls the first telescopic arm 1211, the third telescopic arm 1221, the second telescopic arm 1212 and the fourth telescopic arm 1222 to return to their original positions, and completes the unloading of the container.

[0072] During loading and unloading, the first support column 1215 at one end of the first telescopic arm 1211 and the second support column 1225 at one end of the third telescopic arm 1221 can both play a supporting role, and the first support column 1215 and the second support column 1225 can both be telescoped to adjust the height, such as Figure 3 As shown in the structure, the second support column 1225 may include a second fixed column 12251 and a second movable column 12252 , and may also include a second bracket 12253 for mounting the second roller 1226 .

[0073] The structure of the first container lock 1213 and the second container lock 1223 in the embodiment of the present invention can adopt the structure of the container lock currently available on the market, and the first container lock 1213 and the second container lock 1223 can be manually operated to achieve locking and unlocking; the control device 13 can also use the automatic control method of controlling the container lock in the prior art to control the first container lock 1213 and the second container lock 1223 to lock and unlock, which is not strictly limited in this application.

[0074] In one example, the structures of the first container lock 1213 and the third container lock 1223 in the embodiment of the present invention can be as follows: Figure 5 As shown, the principle of the control device 13 controlling the first container lock 1213 and the third container lock 1223 can be as follows (since the structures of the first container lock 1213 and the third container lock 1223 are the same, the following description is taken as an example of the first container lock 1213):

[0075] The first container lock 1213 includes a housing 12131, a driving device 12132 connected to the control device 13 by signal, a driving rod 12133 connected to the driving device 12132 by transmission, and a locking block 12134 arranged on the top of the driving rod 12133. The driving device 12132 is controlled by the control device 13 to rotate the driving rod 12133 by a set angle, so that the locking block 12134 can be switched between a locked position and an unlocked position; Figure 6 The locking block 12134 shown in the structure is in a locked state, and Figure 7The lock block 12134 shown in the structure is in an unlocked state; in order to cooperate with the locking between the first container lock 1213 and the container or other boxes and other goods, it is necessary to set a lock hole corresponding to the lock block 12134 on the surface of the container so that the lock block 12134 can enter the corresponding lock hole and achieve locking by changing the direction. The first container lock 1213 is not limited to the above mechanical structure, and can also be any other type of locking device such as an electromagnetic lock; when the first container lock 1213 is an electromagnetic lock, the electromagnetic lock is energized to generate electromagnetic force through the signal connection between the control device and the first container lock 1213, and the first container lock 1213 is adsorbed on the container through the electromagnetic force to achieve the locking of the first container lock 1213 and the container.
