[0042] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0043] To solve the technical problems presented in the background art, the present disclosure provides a shelf system for a rail vehicle. The shelf system includes a shelf, a track assembly, and a charging device. Among them, the shelf is configured to carry goods. The track assembly includes two guide rails, which are arranged parallel to each other at a relative interval on the shelf and are configured for the rail vehicle to travel. The charging device is disposed between the two guide rails and connected to the two guide rails, and is configured to charge the rail vehicle.

[0044] The shelf system of the present disclosure disposes the charging device on the track assembly. When designing the shelf system, only need to select a track assembly adapted to the selected rail vehicle according to the selected rail vehicle, then dispose the charging device matching the rail vehicle on the track assembly, and finally install the assembly of the two on the shelf. In this way, the assembly can be used in cooperation with shelves of any size or structure, and there is no need to adjust the design and deployment of the charging device due to the change of the shelf size of different shelf manufacturers, thereby reducing the customized design amount of the charging device and reducing the manufacturing cost.

[0045] For ease of understanding, hereinafter with reference to Figures 1 to 5, in combination with an embodiment, the specific structure and working principle of the shelf system for rail vehicles of the present disclosure will be described.

[0046] It should be noted that in this embodiment, a four-way shuttle is used as the rail vehicle to illustrate the specific structure and working principle of the shelf system of the present disclosure. Of course, in some embodiments, the rail vehicle of the present disclosure can also be other rail vehicles suitable for traveling on the shelf, such as: a tote shuttle.

[0047] Specifically, referring to Figure 1 , generally, the four-way shuttle 1 includes a vehicle body 10, X-direction wheels 11, Y-direction wheels 12, a charging battery (not shown in the figure), a driving battery (not shown in the figure), etc. Among them, the vehicle body 10 is usually a cuboid structure, which is configured to carry goods and store the charging battery, driving unit, etc. The charging battery is used to provide power for the driving unit, and the driving unit is used to drive the X-direction wheels 11 or Y-direction wheels 12 to rotate, so that the four-way shuttle travels along the X-direction or Y-direction on the shelf. A first positive charging terminal 13 and a first negative charging terminal 14 are also provided on the vehicle body 10 of the four-way shuttle 1. The first positive charging terminal 13 and the first negative charging terminal 14 are electrically connected to the charging battery in the vehicle body 10 to form a charging circuit, and the first positive charging terminal 13 and the first negative charging terminal 14 cooperate with an external charging device to form a charging circuit loop to charge the charging battery in the vehicle body 10.

[0048] In addition, the shelf of the present disclosure is a shelf structure composed of standard steel such as columns, crossbeams and support beams. This structure of the shelf has the characteristics of simple assembly and low cost. Of course, in some embodiments, the shelf of the present disclosure can also be a shelf built with the help of a concrete wall structure in cooperation with steel, etc., which is not limited herein.

[0049] Specifically, referring to Figure 2 , the shelf 2 of the present disclosure includes a plurality of columns arranged in a square array and a plurality of crossbeams fixedly connected to the columns and vertically spaced apart. The crossbeams and columns cooperate to form a plurality of storage positions arranged in sequence in the vertical direction and the horizontal direction to store goods. And, inclined support beams are arranged between adjacent two columns to enhance the overall strength of the shelf.

[0050] Continuing to refer to Figure 1 , in addition to the above shelf, in one embodiment, the shelf system of the present disclosure further includes a track assembly. The track assembly includes two guide rails 3. These two guide rails 3 are arranged parallel to each other at a relative interval on the shelf 2 and are configured for the rail vehicle to travel.

[0051] It should be noted that the track assembly disclosed in the present invention refers to two guide rails 3 for the four-way shuttle to travel in one direction, so as to guide the four-way shuttle to travel along the X direction or the Y direction. Of course, the specific structure of the track assembly depends on the actual type of rail vehicle, and is not limited to the structure in this embodiment. It can also be a track assembly composed of straight segments and arc segments similar to trains and subways.

[0052] In addition, the guide rail 3 can be fixedly connected to the shelf by welding, bonding, etc., and it can also be detachably installed on the shelf by fasteners such as bolts.

[0053] Continue to see Figure 1 The rack system of the present disclosure further includes a charging device 4, which is disposed between and connected to the two guide rails 3 and is configured to charge the rail vehicle.

[0054] For details, see Figure 3 In one embodiment, the charging device 4 of the present invention includes a shell 40 and two charging terminals, one of which is a second positive charging terminal 41 and a second negative charging terminal 42, wherein the shell 40 is constructed to be connected to the two guide rails 3, the second positive charging terminal 41 and the second negative charging terminal 42 are arranged on the shell 40, and are electrically connected to the charging circuit of the shell 40, and the charging circuit is electrically connected to the external mains or to the self-contained battery in the shell 40, and when the corresponding two charging terminals of the rail vehicle are respectively connected to the second positive charging terminal 41 and the second negative charging terminal 42 of the charging device 4, a charging circuit loop is formed to charge the rail vehicle.

[0055] Furthermore, the charging device 4 and the guide rail 3 of the present disclosure are pre-positioned by matching positioning pins and positioning holes, and are fixedly connected by matching fasteners and mounting holes.

[0056] For details, see Figure 4 A positioning hole and a first mounting hole are provided on the guide rail 3. Correspondingly, a positioning pin 43 and a second mounting hole are provided on the housing of the charging device. During assembly, the positioning pin on the housing is first inserted into the positioning hole on the guide rail to complete pre-positioning, and then the relative position of the charging device and the guide rail is fine-tuned until the first mounting hole and the second mounting hole are aligned, and finally, fasteners such as bolts or screws are inserted into the first mounting hole and the second mounting hole to fix the charging device on the guide rail.

[0057] It should be noted that, depending on the type of fastener selected, the first mounting hole and the second mounting hole may be a plain hole or a threaded hole.

[0058] Obviously, the charging device and the guide rail of the present disclosure are pre-positioned through a matching positioning pin and positioning hole, and are fixedly connected through a matching fastener and mounting hole, and the quick disassembly and assembly of the charging device and the guide rail are cleverly realized by a simple structure.

[0059] As described in the above embodiment, the positioning pin is arranged on the housing of the charging device, and the matching positioning hole is arranged on the guide rail. It can be understood that the positioning pin and the positioning hole can also be arranged in reverse, that is, the positioning pin is arranged on the guide rail, and the positioning hole is opened on the housing. That is to say, the disclosed charging device and guide rail are pre-positioned through a matching positioning pin and positioning hole, and one of the positioning pin and the positioning hole is arranged on the guide rail, and the other is arranged on the charging device.

[0060] Furthermore, the first mounting hole on the guide rail is a long strip-shaped fixing hole, and its length extension direction is perpendicular to the extension direction of the guide rail. Such a setting can compensate for the dimensional difference between the first mounting hole and the second mounting hole, reduce the processing precision requirements for the first mounting hole and the second mounting hole, and thus reduce the overall cost of the shelf system.

[0061] Continue to refer to Figure 4 , in an embodiment, the guide rail 3 includes a vertical plate 30 and connecting plates 31 and guide plates 32 formed by bending the upper and lower ends of the vertical plate 30 in opposite directions. The connecting plate 31 is provided with a first mounting hole 310 for cooperating with a fastener, and the guide plate 32 is configured to guide the rail vehicle and is provided with a positioning hole 320. Specifically, the bending angles of the connecting plate 31 and the guide plate 32 with respect to the vertical plate 30 are 90°.

[0062] Correspondingly, in combination with Figure 3 and Figure 4 , a positioning pin 43 is provided at the bottom of the housing 40, and two ear plates 44 extend outward from the left and right ends of the housing 40. The charging device 4 is overlapped on the connecting plates 31 of two relatively arranged guide rails 3 through the two ear plates 44 and is provided with a second mounting hole for cooperating with a fastener.

[0063] During assembly, insert the positioning pin 43 on the housing 40 into the positioning hole 320 on the guide plate 32 of the guide rail 3, and overlap the two ear plates 44 on the housing 40 on the connecting plates 31 of the two guide rails 3. Adjust their relative positions until the first mounting hole 310 and the second mounting hole are aligned. Finally, insert the fastener into the first mounting hole 310 and the second mounting hole to connect the guide rail 3 and the charging device 4.

[0064] Obviously, the present disclosure realizes the quick installation of the guide rail 3 and the charging device 4 by using the structure of the guide rail 3 bent into a Z-shaped structure and the housing 40 with outward extension ear plates 44. The structure is simple and easy to operate.

[0065] In combination with Figure 1and Figure 3 In one embodiment, the vehicle body 10 of the four-way shuttle 1 of the present disclosure has two charging terminals, namely a first positive charging terminal 13 and a first negative charging terminal 14. The first positive charging terminal 13 and the first negative charging terminal 14 are electrically connected to a charging battery disposed within the vehicle body 10 through a charging circuit disposed within the vehicle body 10. When the four-way shuttle 1 travels to a position where the first positive charging terminal 13 and the first negative charging terminal 14 respectively cooperate with a second positive charging terminal 41 and a second negative charging terminal 42 on the charging device 4, a complete charging circuit is formed between the four-way shuttle 1 and the charging device 4, and the charging device 4 charges the four-way shuttle 1.

[0066] Specifically, in one embodiment, the first positive charging terminal 13, the first negative charging terminal 14, the second positive charging terminal 41, and the second negative charging terminal 42 of the present disclosure are all charging brush blocks. When the opposite surfaces of the first positive charging terminal 13 and the second positive charging terminal 41 come into contact, and the opposite surfaces of the first negative charging terminal 14 and the second negative charging terminal 42 come into contact, the docking between the four-way shuttle 1 and the charging device 4 is completed, and the charging mode can be activated.

[0067] Of course, in some embodiments, the present disclosure may also use male-female mating charging ports as the charging terminals on the vehicle body and the charging device. In comparison, the present disclosure uses charging brush blocks as the charging terminals on the vehicle body and the charging device, eliminating the need for alignment, plugging and unplugging, etc., and reducing the difficulty of charging implementation.

[0068] More specifically, referring to Figure 5 , in one embodiment, the second positive charging terminal 41 is disposed on the housing 40 in a movable manner, and an elastic element 46 is disposed between the housing 40 and the second positive charging terminal 41.

[0069] Similarly, the second negative charging terminal 42 is disposed on the housing 40 in a movable manner, and an elastic element is disposed between the housing and the second negative charging terminal.

[0070] With such a setting, when the rail vehicle and the charging device 4 cooperate, the elastic element 46 can play a buffering role, avoiding the problem of damage caused by rigid collision between the two, and ensuring the working safety and reliability of the shelf system.

[0071] Continuing to refer to Figure 5 , the second positive charging terminal 41 includes a charging brush head 410 and a pin 411 disposed on the charging brush head 410. The pin 411 penetrates through the housing and extends into the housing 40. A pressing plate 47 and the housing 40 are connected to enclose an installation cavity. The charging mating surface 4100 of the charging brush head 410 penetrates through the pressing plate 47 and extends outwards. The elastic element 46 is disposed within the installation cavity and is located between the charging brush head 410 and the housing 40.

[0072] Similarly, the second negative charging terminal 42 includes a charging brush head and pins disposed on the charging brush head. The pins penetrate through the housing and extend into the housing. The pressing plate and the housing are connected and enclosed to form an installation cavity. The charging mating surface 4100 of the charging brush head penetrates through the pressing plate and extends outside. The elastic element is disposed in the installation cavity and is between the charging brush head and the housing.

[0073] It should be noted that in one embodiment, the elastic element 46 is a compression spring, which is sleeved on the pin 411 and is located between the charging brush head 410 and the housing 40. Of course, in some other embodiments, the elastic element 46 can also be an elastic sleeve with elastic force, etc., and no further examples will be given here.

[0074] It should be noted that in one embodiment, continue to refer to Figure 3 and Figure 5 , the charging device 4 of the present disclosure further includes a first signal terminal 48 and a second signal terminal 49. Among them, the first signal terminal 48 and the second signal terminal 49 are both disposed on the housing, and are configured such that when the first positive charging terminal 13 and the first negative charging terminal 14 of the rail vehicle are respectively docked with the second positive charging terminal 41 and the second negative charging terminal 42 of the charging device, the first signal terminal 48 and the second signal terminal 49 are respectively also docked with the first positive charging terminal 13 and the first negative charging terminal 14, so that the rail vehicle can send a charging signal to the charging device, trigger the control unit in the charging device 4 to send a charging signal, and turn on the charging working mode.

[0075] It can be understood that this embodiment uses the first signal terminal and the second signal terminal to start the charging mode of the charging device only when the rail vehicle reaches the charging position, thereby avoiding the risk of accidental electric shock caused by accidentally starting the charging mode when the rail vehicle is not in place, and ensuring the working safety and reliability of the shelf system.

[0076] Of course, in another embodiment, after the rail vehicle is in place, the charging mode can also be triggered through a mechanical structure. For example, refer to Figure 5 , the second positive charging terminal 41 is movably disposed on the housing 40, and an elastic element 46 is disposed between the housing 40 and the second positive charging terminal 41. Under the elastic force of the elastic element 46, the second positive charging terminal 41 is disconnected from the charging circuit inside the housing 40. When the rail vehicle moves towards the charging device 4, it pushes the second positive charging terminal 41 to move relative to the housing 40 against the elastic force of the elastic element 46 until it is electrically connected to the charging circuit.

[0077] Similarly, the second negative charging terminal 42 is movably arranged on the housing 40, and an elastic element is arranged between the housing and the second negative charging terminal. Under the elastic force of the elastic element, the second negative charging terminal is disconnected from the charging circuit inside the housing. When the rail vehicle moves closer to the charging device, it pushes the second negative charging terminal to move relative to the housing against the elastic force of the elastic element until it is connected to the charging circuit.

[0078] More specifically, the second positive charging terminal 41 includes a charging brush head 410 and a pin 411 arranged on the charging brush head 410. The pin 411 penetrates the housing and extends into the housing 40. The pressure plate 47 and the housing 40 are connected and enclosed to form an installation cavity. The charging mating surface 4100 of the charging brush head 410 penetrates the pressure plate 47 and extends outside. The elastic element 46 is arranged in the installation cavity and is located between the charging brush head 410 and the housing 40.

[0079] Under the elastic force of the elastic element 46, the pin 411 is disconnected from the charging circuit inside the housing 40. When the rail vehicle moves closer to the charging device 4, it pushes the charging brush head 410 to move relative to the housing 40 against the elastic force of the elastic element 46 until the pin 411 is connected to the charging circuit.

[0080] Similarly, the second negative charging terminal 42 includes a charging brush head and a pin arranged on the charging brush head. The pin penetrates the housing and extends into the housing. The pressure plate and the housing are connected and enclosed to form an installation cavity. The charging mating surface of the charging brush head penetrates the pressure plate and extends outside. The elastic element is arranged in the installation cavity and is between the charging brush head and the housing.

[0081] Under the elastic force of the elastic element, the pin is disconnected from the charging circuit inside the housing. When the rail vehicle moves closer to the charging device, it pushes the charging brush head to move relative to the housing against the elastic force of the elastic element until the pin is connected to the charging circuit.

[0082] Continue to refer to Figure 3 , in one embodiment, a stop element 45 is further arranged on the charging device 4 of the present disclosure. The stop element 45 is configured to prevent the rail vehicle from moving closer to the charging device 4 when the two charging terminals of the rail vehicle are in place in cooperation with the two charging terminals on the charging device.

[0083] With such a setting, when the two charging terminals of the rail vehicle are in place in cooperation with the two charging terminals on the charging device 4, the stop element 45 can prevent the rail from moving forward further, so as to avoid the external force applied by the rail vehicle to the charging terminal exceeding the bearing capacity of the elastic element, resulting in the problem that the elastic element fails and the charging terminal cannot be reset.

[0084] Specifically, the stop element 45 of the present disclosure is an elastic stop element, which can absorb part of the impact force of the rail vehicle to avoid the problem of rigid collision damage between the impact force directly acting on the car body and the two. The elastic stop element can be a rubber block or other elastic block structures.

[0085] More specifically, the charging device of the present disclosure includes two stop elements 45, and these two stop elements 45 are respectively arranged on both sides of the two charging ends to ensure the balanced force of the rail vehicle and avoid the risk of lateral tilt and deviation from the guide rail due to unilateral force.

[0086] The various embodiments of the present disclosure have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
