[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0029] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for the sake of convenience of description, the sizes of the various parts shown in the drawings are not drawn in actual proportional relationship.

[0031] As shown in the figure, the rail walking system includes a vehicle 1 and a first moving rail 3.

[0032] The vehicle 1 includes driving wheels, and the driving wheels include rotatable gears 12; in the logistics system, the vehicle 1 includes a logistics vehicle.

[0033] The first moving rail 3 is for the vehicle 1 to travel on, the first moving rail 3 includes a rack 32, and the first moving rail has a mating area for mating with the driving wheels when the driving wheels start to enter the first moving rail 3.

[0034] When the vehicle 1 switches from another rail to enter the first moving rail 3, the driving wheels need to enter the first moving rail 3 through mating with the mating area of the first moving rail, that is, the mating area is also the entrance area for the vehicle to enter the first moving rail 3.

[0035] The first moving track 3 is also provided with only one guiding tooth 36 in the mating area and a reset device 34 disposed between the guiding tooth 36 and the rack 32. The guiding tooth 36 is disposed on one side of the rack 32 in the width direction and is movably arranged relative to the rack 32.

[0036] The only one guiding tooth 36 means that there is only one guiding tooth 36 in the mating area of the first moving track 3. Only one guiding tooth 36 that is movable relative to the rack 32 is provided outside the rack 32, and no guiding tooth 36 is provided on the rack 32. Setting only one guiding tooth 36 in the mating area can simplify the structure of the mating area, which is beneficial to the processing and production of the mating area.

[0037] The mating area is configured such that during the process of the driving wheel starting to enter the first moving track, when the gear 12 moves along the tooth width direction of the rack and approaches the rack 32, the guiding tooth 36 contacts the teeth of the gear 12 to guide the gear 12 to the circumferential position where it can mesh with the rack 32. After the guiding tooth 36 approaches the rack 32 under the pressure of the gear 12, the reset device 34 resets the guiding tooth 36 in the direction away from the rack 32.

[0038] As Figure 1 and Figure 5 shown, during the movement of the gear 12, when the circumferential position of the gear 12 cannot mesh correctly with the rack 32, the teeth of the gear 12 will contact the guiding tooth 36, and the teeth of the gear 12 will exert pressure on the guiding tooth 36. Under the action of the pressure, the guiding tooth 36 will approach the rack 32, and the distance a between the guiding tooth 36 and the rack 32 will decrease. At the same time, the guiding tooth 36 will exert a reaction force on the teeth, and under the reaction force of the guiding tooth 36, the gear 12 will rotate, so that the circumferential position changes to the position where it can mesh correctly with the rack 32. As Figure 1 shown, the guiding tooth 36 is installed aligned with the teeth of the rack 32. After the gear 12 meshes correctly with the rack 32 and the gear 12 no longer exerts pressure on the guiding tooth 36, the compressed guiding tooth 36 will move away from the rack 32 under the action of the reset device to the initial reset position.

[0039] In the track walking system of this embodiment, by setting only one guiding tooth 36 in the mating area between the first moving track and the driving wheel, and the guiding tooth 36 is movably arranged relative to the rack 32. When the gear 12 of the driving wheel moves along the width direction of the rack 32 and approaches the rack 32, the guiding tooth 36 can effectively guide the gear 12 to the circumferential position where it meshes with the rack 32, enabling the gear 12 to mesh with the rack 32 conveniently and accurately. The structure is simple, convenient and effective, and is convenient for production and manufacturing.

[0040] In some embodiments, such as Figures 1 to 3As shown, in the mating area, the first moving track further includes a mounting member slidably connected to the rack 32, and a guiding tooth 36 is provided on the mounting member. The guiding tooth 36 is slidably connected to the rack 32 through the mounting member, and the movement of the guiding tooth 36 can be more stable when it is compressed.

[0041] In some embodiments, the reset device 34 includes an elastic member provided between the rack 32 and the mounting member. As Figure 1 and Figure 3 shown, the reset device 34 may include an elastic member such as a spring.

[0042] In some embodiments, as Figures 1 to 3 shown, in the mating area, the rack 32 includes a blind hole 323 extending in the tooth width direction. The bottom surface and the orifice of the blind hole 323 are located at opposite ends of the rack 32 along the tooth width direction of the rack 32, and the elastic member is provided in the blind hole 323. The provision of the blind hole 323 can make the installation and action of the elastic member more stable and reliable. The bottom surface and the orifice of the blind hole 323 are located at both ends of the rack respectively, which can increase the depth of the blind hole and improve the installation reliability of the elastic member.

[0043] In some embodiments, as Figures 1 to 3 shown, in the mating area, the rack 32 further includes a through hole 322 extending in the tooth width direction. The mounting member includes a sliding member 351 that is in clearance fit with the through hole 322 and a plate body 352 fixedly connected to the sliding member 351, and the guiding tooth 36 is provided on the plate body 352.

[0044] In some embodiments, the sliding member 351 includes a pin shaft 3511 that is in clearance fit with the through hole 322. A ring plate 3512 is provided at the end of the pin shaft 3511 that is outside the through hole 322 and away from the plate body 352, and the diameter of the ring plate 3512 is greater than the diameter of the through hole 322. The provision of the ring plate can make the axial positioning of the pin shaft 3511 more accurate, limit the further movement of the plate body away from the rack, and at the same time, the spring does not need to be fixedly connected to the bottom surface in the blind hole, which is convenient for the installation of the spring in the blind hole.

[0045] In some embodiments, as Figures 1 to 3 shown, in the mating area, the rack 32 further includes a groove 321 provided at one end along the tooth width direction, and the plate body 352 is located in the groove 321. The provision of the groove 321 can prevent the plate body 352 from further protruding from the rack in the direction away from the rack, make the structure of the first moving track more compact, and reduce the interference with the gear 12.

[0046] In some embodiments, as Figures 1 to 3As shown, along the tooth width direction of the rack 32, the guiding tooth 36 is provided with a first pointed portion, and the tip of the first pointed portion faces away from the rack 32. In some embodiments, the first pointed portion includes two inclined surfaces located on both sides of the tip, and the inclined surfaces are inclined towards the rack 32. In the embodiment shown in the figure, the tip 363 of the first pointed portion is in a straight line shape, and the two inclined surfaces include a first inclined surface 361 and a second inclined surface 362 located on both sides of the tip 363 of the first pointed portion. The inclined surfaces being inclined towards the rack 32 means that as the inclined surfaces extend away from the tip, they gradually approach the rack 32. This setting can more effectively guide the gear 12.

[0047] In some embodiments, as Figures 1 to 3 shown, the tip is inclined towards the rack 32. When the tip 363 of the first pointed portion extends away from the rack 32 along the tooth height direction of the rack 32, it gradually approaches the rack 32. This setting can more effectively guide the gear 12.

[0048] In some embodiments, as Figure 1 、 Figure 2 and Figure 4 shown, on the end face of the tooth of the gear 12 in the direction away from the vehicle, a second pointed portion is provided. When the gear 12 moves axially along the driving wheel towards the rack 32, the tip of the second pointed portion faces the rack 32. As shown in the figure, the tip 121 of the second pointed portion is in a straight line shape and faces the rack 32. This setting can enable the guiding tooth 36 to more effectively guide the gear 12.

[0049] In some embodiments, as Figure 1 shown, the track walking system is configured such that when the driving wheel cooperates with the mating area and the gear 12 moves axially along the driving wheel towards the rack 32, the position of the axis of the gear 12 and the center line of the guiding tooth 36 is different in the extending direction of the rack 32.

[0050] That is, when the vehicle in the track walking system enters the first moving track, the axes of the gear 12 at the entry point and the guiding tooth are misaligned, as shown by the dashed lines x and y in the figure. This setting helps to avoid the phenomenon that the tip of the tip of the second pointed portion of the gear 12 and the tip of the first pointed portion of the guiding tooth exactly align. Even if the tip of the tip of the second pointed portion and the tip of the first pointed portion of the guiding tooth come into contact, the tip of the tip of the second pointed portion and the tip of the first pointed portion of the guiding tooth will cross. As the guiding tooth is compressed and approaches the rack, the tip of the tip of the second pointed portion and the tip of the first pointed portion of the guiding tooth will gradually separate, so that the gear can be correctly guided and the meshing of the gear and the rack can be more reliable and effective.

[0051] In some embodiments, as Figure 5 and Figure 6As shown, the rail walking system further includes a second moving rail 2 for vehicle travel, and the mating area is used for mating with the driving wheels when the vehicle switches from the second moving rail 2 to the first moving rail 3.

[0052] In some embodiments, the first moving rail is for vehicle travel. The first moving rail includes a rack 32 and a guiding portion located on one side of the rack 32 in the tooth width direction. The guiding portion is used for guiding the guiding wheel 13 when the vehicle travels on the first moving rail. The guiding portion is located on the side of the rack 32 close to the vehicle. The guiding portion includes a first guiding bar 311 and a second guiding bar 312 that are oppositely arranged and have the same extending direction as the extending direction of the rack 32. The distance between the first guiding bar 311 and the second guiding bar 312 is greater than the diameter of the guiding wheel 13. The first moving rail is configured such that during the process of the driving wheel moving in the tooth width direction of the rack 32 and mating with the mating area of the first moving rail, the gear 12 passes through the first guiding bar 311 and the second guiding bar 312 and then meshes with the rack 32. When the gear 12 meshes with the rack 32, the guiding wheel 13 is located between the first guiding bar 311 and the second guiding bar 312. The first moving rail 3 is a vertical rail, the second moving rail 2 is a horizontal rail, and the first moving rail 3 includes a U-shaped column 33 that surrounds the outside of the guiding portion and the rack 32 and extends in the vertical direction. The first guiding bar 311 and the second guiding bar 312 are respectively arranged on two opposite inner walls of the U-shaped column 33.

[0053] In some embodiments, as Figure 5 and Figure 6 shown, the driving wheel further includes a walking wheel 11 surrounding the outside of the guiding wheel 13, and the vehicle travels on the second moving rail through the walking wheel 11. The gear 12 and the guiding wheel 13 can axially expand and contract relative to the walking wheel 11. When the vehicle travels on the second moving rail, the gear 12 and the guiding wheel 13 axially retract, and the walking wheel 11 rotates and travels on the second moving rail. When the vehicle switches to the first moving rail, the gear 12 and the guiding wheel 13 axially extend outward relative to the walking wheel 11, the walking wheel 11 does not extend, and the gear 12 and the guiding wheel 13 start to mate with the mating area on the first moving rail.

[0054] In some embodiments, the first moving rail 3 is a vertical rail, and the rail walking system includes a plurality of second moving rails 2 that intersect the first moving rail 3 and are distributed in the vertical direction. The second moving rails 2 are horizontal rails. The second moving rails 2 include a first sub-horizontal rail and a second sub-horizontal rail that extend in the same direction, are spaced apart, and both intersect the first moving rail 3. The distance between the first sub-horizontal rail and the second sub-horizontal rail 22 is less than the distance between the first guiding bar 311 and the second guiding bar 312.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that it is still possible to modify the specific implementation manners of the present invention or perform equivalent replacements on some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
