DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] It should be noted that relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variation thereof are intended to cover non-exclusive inclusion, so 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 an..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.

[0026] The features and performance of the present invention will be further described in detail below with reference to the embodiments.

[0027] Please refer to Figure 1, A multi-layer shuttle vehicle running drive device that uses in-wheel motors to increase space, including a main body 5 and a secondary body 6, which provide a loading platform for electrical components; the main body 5 and the secondary body 6 are connected by a connection component 7, and the connection component 7 carries a cargo position positioning and detection component 10; on the main body 5 and the secondary body 6, there are respectively provided a driving wheel assembly 1 and a driven wheel assembly 3 for the multi-layer shuttle vehicle to move horizontally along the track. The driving wheel assembly 1 includes a bearing bracket and an in-wheel motor, and the in-wheel motor is integrated into the wheel to provide driving force for the multi-layer shuttle vehicle to move horizontally along the track; a guiding wheel assembly 4 is provided at the front end of the side surface of the main body 5; a fork 2 and a cargo position positioning and detection component 10 are provided on the connection component 7.

[0028] Drive mode change: Replace the traditional servo motor or AC motor with an in-wheel motor. The in-wheel motor integrates the motor and the wheel, eliminating the transmission system of the traditional drive device, reducing mechanical components, and improving drive efficiency;

[0029] Improve usable space: Since the in-wheel motor is directly installed in the wheel, the internal structure of the entire device is more compact, thus increasing the internal usable space of the multi-layer shuttle vehicle;

[0030] Reduce maintenance costs: The in-wheel motor reduces mechanical components such as belts and gears, reduces the failure rate, and has relatively low maintenance costs;

[0031] Improve energy efficiency: The in-wheel motor has a high torque density, can provide higher drive performance at lower energy consumption, and improves the overall energy efficiency.

[0032] Under the driving wheel assembly 1, there is a wheel pressure increasing combination 11 and a pressure rod combination 12 to increase the driving wheel pressure. The wheel pressure increasing combination 11 and the pressure rod combination 12 include a pressing wheel, a pressing sleeve, and a spring group. The wheel pressure increasing combination 11 and the pressure rod combination 12 apply pressure to the lower surface of the track, increasing the driving wheel pressure, thereby increasing the maximum acceleration of the shuttle vehicle.

[0033] At the four corners of the main body 5 and the secondary body 6, there are buffer brush supports 9 for cleaning the dust on the track.

[0034] On the connection component 7, there is also a lifting plate assembly 8 that provides support and guidance for the smooth movement of goods onto the multi-layer shuttle vehicle.

[0035] At the front end of the main body 5, there is also an end deceleration photoelectric switch support 13. The end deceleration photoelectric switch support 13 detects the position and speed of the multi-layer shuttle vehicle to determine if it has reached a specific position. The end deceleration photoelectric switch support 13 is installed at the end of the mechanical device to emit a signal when an object approaches the end point, thereby realizing the function of deceleration or stopping.

[0036] The fork 2 includes a hook fork device, a hook fork motor and a detection system. The fork 2 is driven by a fork drive assembly and the left-right translation for picking and placing goods is completed by a toothed belt transmission mechanism. The fork 2 is a double-depth fork, and four hooks are provided on one fork body, so that materials can be placed at four positions on the left and right sides.

[0037] The driven wheel assembly 3 cooperates with the driving wheel assembly 1 to support the multi-layer shuttle car. For the vehicle model using bar code positioning, the driven wheel assembly 3 includes a running wheel, a bearing and a bearing seat.

[0038] The guide wheel assembly 4 includes a guide wheel seat, a guide wheel and a bearing. The guide wheel assembly 4 enables the multi-layer shuttle car to always run along the track without deviating from the track.

[0039] The goods location positioning detection assembly 10 monitors the specific location of the multi-layer shuttle car in the warehouse or storage area in real time to ensure the safe and accurate storage of goods.

[0040] The above-described embodiments only represent the specific implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the protection scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the technical solution of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
