[0025] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0026] A body structure of a shuttle vehicle, comprising a body frame 01, a running wheel assembly, a driving assembly, and a transmission assembly; the driving assembly and the transmission assembly are located inside the body frame 01, and the running wheel assembly is located outside the body frame 01;

[0027] The travel wheel assembly comprises a first travel wheel group and a second travel wheel group, the first travel wheel group drives the vehicle body to travel along a first direction, and the second travel wheel group drives the vehicle body to travel along a second direction, and the first direction is perpendicular to the second direction.

[0028] In one embodiment, if Figure 1-6 As shown, the shuttle car provided by the present application includes at least a body frame 01 that is approximately square or approximately rectangular, and two sets of running wheel groups are arranged on the outside of the body frame 01, which are a first running wheel group and a second running wheel group. The first running wheel group drives the body to move along a first direction F1, and the second running wheel group drives the body to move along a second direction F2. The F1 direction is perpendicular to the F2 direction. The shuttle car provided by the present application is a rail trolley used in a three-dimensional warehouse. A cargo space is provided in the three-dimensional warehouse, and a first track for the shuttle car to move is provided under the cargo space. A lane is provided in the three-dimensional warehouse, and a second track for the trolley to move is provided on the lane. The shuttle car switches direction at the intersection of the first track and the second track. The F1 direction corresponds to the first track direction for the shuttle car to enter and exit the cargo space, and the F2 direction corresponds to the second track direction for traveling in the lane of the three-dimensional warehouse.

[0029] The shuttle vehicle is provided with a driving assembly, which includes a first driving motor 1 and a second driving motor 2. The first driving motor 1 is used to drive the walking wheel assembly to drive the vehicle body to walk. The first driving motor 1 has at least two output shafts, and different output shafts are respectively connected to the first walking wheel assembly and the second walking wheel assembly; the second driving motor 2 is used to drive the second walking wheel assembly to rise and fall. A reducer is also provided between the first driving motor 1 and the walking wheel assembly, and the second driving motor 2 is connected to the reducer, and the second walking wheel assembly is driven to rise and fall through the reducer.

[0030] One of the output shafts of the first drive motor 1 is transmission-connected to the first travel wheel set via a first transmission shaft 11 , and the other output shaft of the first drive motor 1 is transmission-connected to the second travel wheel set via a universal joint transmission shaft 12 .

[0031] In one embodiment, the first driving motor 1 is connected to a reducer, and two output shafts are arranged in front of the reducer, one of which drives the shuttle car to move in the first direction through the first transmission shaft 11. Specifically, the first walking wheel group includes at least one group of first driving wheels 1A and at least one group of first driven wheels 2A, each group of first driving wheels 1A includes two driving wheels, and the two groups of first driving wheels 1A are symmetrically arranged on both sides of the vehicle body. The first transmission shaft 11 passes through the vehicle body frame 01, and sprockets are arranged at the two ends of the first transmission shaft 11 extending outside the vehicle body frame 01. The sprockets rotate with the first transmission shaft 11, and the sprockets are connected to the first driving wheels 1A through a chain. It can be understood that if multiple first driving wheels 1A are arranged on the same side of the vehicle body, the multiple first driving wheels 1A are driven by chains, and the chains are arranged outside the vehicle body frame. In one embodiment, two driving wheels are arranged on the same side of the vehicle body, and the sprockets are connected to one of the driving wheels through a chain, and one of the driving wheels is connected to the other driving wheel on the same side through a chain to drive each other. The other output shaft of the first drive motor 1 is connected to the second running wheel set through a universal joint drive shaft 12. Since the shuttle needs to move in two directions, the present application performs reversing by jacking. In fact, during the movement of the shuttle, only the running wheels in one direction are pressed on the track for movement. When the shuttle needs to move in the F1 direction, the second running wheel set in the F2 direction is suspended in the air and does not contact the track. Similarly, when the shuttle needs to move in the F2 direction, the first running wheel set in the F1 direction is suspended in the air and does not contact the track.

[0032] The first running wheel assembly is mounted on the vehicle body frame 01 , and the second running wheel assembly is connected to the second drive motor 2 via a mounting plate 22 ; the second running wheel assembly and the mounting plate 22 are raised and lowered synchronously.

[0033] In one embodiment, the first running wheel group includes eight wheels, including four first driving wheels 1A and four first driven wheels 2A. Two first driving wheels 1A and two first driven wheels 2A are installed on each of the two side panels of the vehicle frame 01 in the first driving direction, and the two first driving wheels 1A on each side are chain-driven. The second running wheel group also includes eight wheels, including four second driving wheels 1B and four second driven wheels 2B. On both sides of the vehicle body in the second driving direction, a mounting plate 22 is provided on each side, and two second driving wheels 1B and two second driven wheels 2B are installed on the mounting plate 22 on each side. The mounting plate 22 is connected to the vehicle frame 01 through a cam lifting mechanism, and the universal joint drive shaft 12 passes through the side panels of the vehicle frame 01 and the mounting plates 22 on both sides and is connected to the second driving wheels 1B on both sides through a sprocket chain, and the two second driving wheels 1B on each side are chain-driven. Since the first drive motor 1 and the second drive wheel 1B are connected to each other through the universal joint transmission shaft 12, when the mounting plate 22 drives the second running wheel set to rise and fall, the first drive motor 1 does not rise and fall accordingly.

[0034] In one embodiment, the first drive motor 1 and the second drive motor 2 are located on one side of the first walking direction of the inner wall of the vehicle body. Installing the drive motor on one side of the first walking direction of the inner wall of the vehicle body can, on the one hand, leave more space for the battery assembly and the control assembly, and on the other hand, it is convenient to set the transmission shaft to drive the driving wheels in the two walking directions without interfering with the lifting device, so that the lifting transmission device can be set on the left and right sides of the first walking direction.

[0035] The transmission assembly includes a lifting transmission assembly, and the lifting transmission assembly includes a transmission box 4 and a second transmission shaft 21. The second transmission shaft 21 is installed on the side close to the drive motor in the first walking direction, and the lifting transmission assembly is located on the left and right sides of the second walking direction. The second transmission shaft 21 is used to connect the lifting transmission assemblies located on the left and right sides of the second walking direction. The transmission box 4 is connected to the mounting plate 22 of the second walking wheel group outside the vehicle body frame 01 through a cam structure or a crank structure.

[0036] In one embodiment, the second transmission shaft 21, the first drive motor 1, the second drive motor 2, and the universal joint transmission shaft 12 are located on the same side of the first walking direction, the first drive motor 1 and the second drive motor 2 are located between the second transmission shaft 21 and the universal joint transmission shaft 12, the output shaft of the first drive motor 1 drives the universal joint transmission shaft 12 through a sprocket chain, the first transmission shaft 11 is vertically arranged to the second transmission shaft 21, and the first transmission shaft 11 divides the space inside the vehicle body frame 01 into a Q1 area and a Q2 area, the Q1 area is used to place the battery assembly, and the Q2 area is used to place the control assembly.

[0037] In one embodiment, the shuttle vehicle includes two transmission boxes 4, which are respectively located on both sides of the inner wall of the vehicle frame 01 in the second travel direction. Each transmission box 4 has at least one transmission shaft output, and the output transmission shaft passes through the inside of the vehicle frame 01 and is connected to the mounting plate 22 of the second travel wheel set through a cam structure or a crank structure. The cam structure or the crank structure rotates to drive the mounting plate 22 to rise and fall. In one embodiment, each transmission box 4 has two transmission output shafts, and the transmission box 4 is internally driven by multiple gears.

[0038] In one embodiment, the shuttle vehicle includes a support plate 33, and the support plate 33 is lifted and lowered following the lifting and lowering of the mounting plate 22. A lifting guide support 8 is provided on the inner wall of the vehicle frame 01, and the support plate 33 is connected to the lifting guide support 8. The support plate 33 is used to lift the goods. The support plate 33 is installed on the mounting plate 22 and is lifted and lowered following the lifting and lowering of the mounting plate 22. When the mounting plate 22 is in the first state, the second running wheel group contacts the track, and the shuttle vehicle travels in the second direction. When the mounting plate 22 is in the second state, the second running wheel group rises and does not contact the track, and the shuttle vehicle travels in the first direction. When the mounting plate 22 is in the third state, the support plate 33 lifts the goods, and the height of the mounting plate 22 increases from the first state to the third state. In this application, the reversing lifting and lifting of the goods are set on the same lifting structure, and different lifting heights are achieved by controlling the stroke of the cam structure or the crank structure. On the one hand, the structure is simplified, and on the other hand, the overall height of the vehicle body is reduced, which is conducive to improving the storage density of the stereoscopic warehouse.

[0039] In one embodiment, the shuttle vehicle further comprises a support block 10, and the support block 10 is connected to the mounting plate 22. The outer side of the running wheel of the shuttle vehicle is also provided with a side plate housing, such as Figure 2 As shown in the figure, the second driving wheel 1B is shown. To facilitate the display of the wheel structure, the side panel shells at other wheels are not shown in the figure. The support block 10 is located between the mounting plate 22 and the side panel shell to bear the load.

[0040] In one embodiment, the travel wheel assembly includes a driven wheel, at least one of which is connected to an encoder wheel 6 through a synchronous transmission member, and an encoder 7 is installed on the encoder wheel 6. The present application sets an encoder wheel 6, and an encoder 7 is installed on the encoder wheel 6 to detect the travel accuracy of the power device and related abnormal alarms. In the present application, a synchronous belt and a synchronous pulley are set on the rotating shaft of the driven wheel, and the synchronous belt is connected to the encoder wheel to drive the encoder wheel 6 to rotate.

[0041] In one embodiment, the shuttle car further includes a sensor, which is installed on the periphery of the car body, and the sensor includes a visual sensor and a photoelectric sensor. The sensors arranged on both sides of the first travel direction of the present application are arranged obliquely, so that when the shuttle car moves from the track in the first direction to the track in the second direction, the sensor can detect whether there is a vehicle on the track in the second direction, and judge whether there will be a collision when the shuttle car moves to the track in the second direction. That is to say, when the shuttle car travels from the track under the cargo space to the track in the lane, it is necessary to judge whether there are other shuttle cars or obstacles at the position of the conversion plate for changing direction.

[0042] In one embodiment, the shuttle vehicle further includes an identification structure reading device 9, which is located at the bottom of the vehicle body. The identification structure reading device 9 is used to obtain the vehicle point information and determine the vehicle is currently located at or passing a certain position. The identification structure reading device 9 is a code reader or a visual device.

[0043] In one embodiment, the shuttle vehicle further includes a traction device 3, which is arranged on the periphery of the vehicle body. The traction device 3 is arranged in the first walking direction and is used to install a traction rope, etc. When the vehicle body fails and cannot move, a traction rope can be installed on the traction device 3 to tow the faulty vehicle away from the track in the first direction.

[0044] In one embodiment, the shuttle vehicle further comprises guide wheels 5, which are arranged on both sides of the vehicle body in the first travel direction. The guide wheels 5 play a guiding role when the vehicle body travels in the first direction, so as to keep the vehicle body running in the center of the first track.
