Description

Technical Field

[0001] This utility model relates to the technical field of shared bicycle placement devices, and in particular to a shared bicycle placement device and a bicycle storage and retrieval device. Background Technology

[0002] Shared bicycles, as an effective tool for solving the "last mile" problem in cities, have alleviated urban traffic pressure to some extent due to their lightweight and flexible features. However, their "park anywhere" model has also led to the widespread phenomenon of haphazard parking, especially in densely populated areas such as bus stops and subway entrances, where a large number of vehicles have seriously encroached on public space and affected the city's appearance and traffic order.

[0003] To restore order at stations and improve vehicle turnover efficiency, shared bicycle operators currently generally use truck transport for manual dispatching. This method is highly labor-intensive, requiring staff to load shared bicycles one by one into the truck bed and arrange them closely based on experience, relying on the frames to lean against each other for initial fixation. This method not only subjects staff to significant labor intensity, but also, due to the lack of independent fixation during transport, the bicycles are prone to tipping over due to road bumps or unstable riding, resulting in scratches, deformation, and other damage, increasing maintenance costs and vehicle depreciation rates. Summary of the Invention

[0004] In view of this, it is necessary to provide a shared bicycle placement device to solve the technical problem of manually dispatching shared bicycles using the existing method of truck transportation. This method requires staff to carry the shared bicycles one by one into the truck and arrange them closely based on experience, relying on the mutual support of the bicycles to achieve initial fixation. This method not only puts the staff under great labor intensity, but also makes the vehicles prone to tipping over due to road bumps or vehicle swaying during transportation, resulting in damage such as scratches and deformation of the bicycle body, which increases the maintenance cost and vehicle depreciation rate.

[0005] It is also necessary to provide a parking and retrieval vehicle.

[0006] On one hand, the present invention provides a shared bicycle placement device, including a storage platform and two circulation guide components. The storage platform is hollow inside, and two U-shaped through slots are symmetrically opened on the upper surface of the storage platform. The horizontal slots of the U-shaped through slots are located at the front end of the storage platform, and the vertical slots of the U-shaped through slots extend to the rear end of the storage platform. The distance between the adjacent vertical slots of the two U-shaped through slots is adapted to the distance between the two wheels of the shared bicycle. The two circulation guide components are correspondingly arranged with the two U-shaped through slots.

[0007] Each of the circulating guide components includes a circulating drive unit and several clamping units. The circulating drive unit is laid in the storage platform along the trajectory of the "U"-shaped through groove. Several clamping units are disposed on the circulating drive unit, and the upper parts of several clamping units extend out of the storage platform through the "U"-shaped through groove. Two clamping units on adjacent longitudinal slots of two "U"-shaped through grooves clamp the two wheels of the shared bicycle. The circulating drive unit drives the clamping units to move forward along the trajectory of the "U"-shaped through groove for storage or to move backward for retrieval.

[0008] Preferably, the cyclic drive unit includes two longitudinal guides, a transverse connector, and two pushers. The two longitudinal guides are laid in the storage platform along the two longitudinal slots of the "U"-shaped through groove. The transverse connector is laid in the storage platform along the transverse slot of the "U"-shaped through groove. The two pushers are both disposed on the storage platform near the transverse slot of the "U"-shaped through groove. The output ends of the two pushers extend into the storage platform, and the output ends of the two pushers push along the two longitudinal slots of the "U"-shaped through groove. A plurality of clamping parts are spaced apart above the longitudinal guides and the transverse connector. The pushers are used to push the clamping parts above the transverse connector into the longitudinal guides, so that the longitudinal guides and the transverse connector jointly drive the clamping parts to move along the trajectory of the "U"-shaped through groove.

[0009] Preferably, the cyclic drive unit further includes two limiting blocks, which are respectively disposed on one end of the two longitudinal guides near the transverse connector. The limiting blocks are used to intercept and position the clamping parts on the longitudinal guides so that the two clamping parts at the front ends of the two longitudinal guides are facing each other.

[0010] Preferably, the storage platform has four through holes at its bottom, which are correspondingly located on the four longitudinal guides near one end of the transverse connector. The limiting block includes a first drive motor, a guide sleeve, and a lifting rack. The first drive motor is installed inside the storage platform and is located on one side of the through hole. The guide sleeve is vertically connected to the bottom of the storage platform, and the opening of the guide sleeve is disposed on the through hole. One end of the lifting rack meshes with the output end of the first drive motor, and the other end of the lifting rack extends through the through hole into the guide sleeve. The first drive motor drives the lifting rack to move up and down within the guide sleeve, so that the top end of the lifting rack rises and intercepts and positions or lowers to release the clamping part on the longitudinal guide.

[0011] Preferably, the cyclic drive unit further includes a first photoelectric switch, a second photoelectric switch, a third photoelectric switch, and a fourth photoelectric switch. The first photoelectric switch is disposed on one side of the adjacent longitudinal slots of the two "U"-shaped through slots, and is located between the limiting block and the transverse connecting member. The first photoelectric switch is used to control the limiting block on the adjacent longitudinal slots of the two "U"-shaped through slots to intercept the clamping part. The second photoelectric switch is disposed on the opposite side of the longitudinal slots of the two "U"-shaped through slots, and is located between the limiting block and the transverse connecting member. The second photoelectric switch is used to control the limiting block on the opposite side of the longitudinal slots of the two "U"-shaped through slots to intercept the clamping part. The third photoelectric switch and the fourth photoelectric switch are respectively disposed on the two pushing members, and are used to control the two pushing members to push the clamping part.

[0012] Preferably, the clamping part includes a movable support base, a second drive motor, and a gripper. The movable support base is located between the cyclic drive unit and the upper plate of the storage platform. The cyclic drive unit drives the movable support base to move along the trajectory of the "U"-shaped through groove. The second drive motor is located inside the movable support base. The gripper is located on both sides of the movable support base. One end of the gripper is rotatably connected to the movable support base, and the other end of the gripper extends out of the storage platform through the "U"-shaped through groove. The output end of the second drive motor is connected to the middle of the gripper. The second drive motor drives the gripper to close or open so that the gripper clamps the wheel of the shared bicycle.

[0013] Preferably, the upper part of the movable support base has a boss, the width of which is adapted to the width of the longitudinal groove of the "U"-shaped through groove, the length of which is adapted to the width of the transverse groove of the "U"-shaped through groove, the boss extends out of the "U"-shaped through groove and abuts against the groove edge of the "U"-shaped through groove, so that the boss guides the movable support base to move along the trajectory of the "U"-shaped through groove.

[0014] Preferably, the gripper includes two rocker arms, a connecting block, and two sets of connecting plates. One rocker arm is located at the front end of the movable support base, and the other rocker arm is located at the rear end of the movable support base. The bottom ends of both rocker arms are hinged to the movable support base. The connecting block is located above the movable support base and between the two rocker arms. One end of each set of connecting plates is hinged to both sides of the connecting block, and the other end of each set of connecting plates is hinged to the middle of the two rocker arms. The output end of the second drive motor is connected to the middle of the connecting block. The second drive motor drives the connecting block to rise or fall. The connecting block drives the two rocker arms to rotate towards each other to clamp and close, or to rotate away from each other to open and release.

[0015] Preferably, wheel contour grooves are formed on the upper opposite surfaces of both rocker arms.

[0016] On the other hand, this utility model also provides a storage and retrieval vehicle, which includes the shared bicycle placement device described in the previous aspect.

[0017] As can be seen from the above technical solution, the present invention provides a shared bicycle placement device and bicycle storage and retrieval device, wherein the shared bicycle placement device includes a storage platform and two circulation guide components. The storage platform is hollow inside, and two "U"-shaped through slots are symmetrically opened on the upper surface of the storage platform. The horizontal slots of the "U"-shaped through slots are located at the front end of the storage platform, and the vertical slots of the "U"-shaped through slots extend to the rear end of the storage platform. The distance between adjacent vertical slots of the two "U"-shaped through slots is adapted to the distance between the two wheels of the shared bicycle. The two circulation guide components are connected to the two "U"-shaped through slots. The circulation guide assembly includes a circulation drive unit and several clamping units. The circulation drive unit is laid along the trajectory of the "U"-shaped groove within the storage platform. The clamping units are all mounted on the circulation drive unit, and the upper parts of each clamping unit extend through the "U"-shaped groove and out of the storage platform. When using this invention to store shared bicycles, staff only need to move the shared bicycle to the front end of the storage platform. The two clamping units located at the front ends of the adjacent longitudinal openings of the two "U"-shaped grooves clamp the two wheels of the shared bicycle. The circulation drive unit drives the two "U"-shaped grooves... The clamping parts on the adjacent longitudinal slots move forward toward the rear of the storage platform to complete the storage process. During this process, unlike traditional truck transport where staff manually load shared bicycles one by one into the truck bed and arrange them tightly for mutual support, this invention uses two clamping parts to independently secure the wheels, effectively preventing tipping and damage caused by collisions or instability during movement. When retrieving shared bicycles, the circulating drive unit drives the clamping parts on the adjacent longitudinal slots of the two "U"-shaped through slots forward toward the front of the storage platform. The end moves in the opposite direction to transport the shared bicycle to a convenient location for retrieval, thus completing the exit. The circulating drive unit can drive the clamping parts on the adjacent longitudinal slots of the two "U"-shaped channels to flow through the transverse slots of the "U"-shaped channels into the adjacent longitudinal slots of the two "U"-shaped channels. The circulating drive unit can also drive the clamping parts on the opposite longitudinal slots of the two "U"-shaped channels to flow through the transverse slots of the "U"-shaped channels into the adjacent longitudinal slots of the two "U"-shaped channels, so that the clamping parts circulate in the "U"-shaped channels, ensuring that staff can more conveniently store and retrieve shared bicycles.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] On the one hand, please refer to Figures 1 to 5The present invention provides a shared bicycle placement device 10, including a storage platform 110 and two circulation guide components 120. The storage platform 110 is hollow inside, and two "U"-shaped through slots 111 are symmetrically opened on the upper surface of the storage platform 110. The horizontal slot of the "U"-shaped through slot 111 is located at the front end of the storage platform 110, and the vertical slot of the "U"-shaped through slot 111 extends to the rear end of the storage platform 110. The distance between the adjacent vertical slots of the two "U"-shaped through slots 111 is adapted to the distance between the two wheels of the shared bicycle. The two circulation guide components 120 are correspondingly arranged with the two "U"-shaped through slots 111.

[0030] Each circulation guide component 120 includes a circulation drive unit 121 and several clamping units 122. Specifically, the number of clamping units 122 depends on the size of the storage platform 110 and the planned storage capacity in actual application. For example, the clamping units 122 can be one, two, three, or four. The circulation drive unit 121 is laid in the storage platform 110 along the trajectory of the "U"-shaped through groove 111. Several clamping units 122 are all set on the circulation drive unit 121, and the upper parts of several clamping units 122 extend out of the storage platform 110 through the "U"-shaped through groove 111. Two clamping units 122 on the adjacent longitudinal slots of the two "U"-shaped through grooves 111 clamp the two wheels of the shared bicycle. The circulation drive unit 121 drives the clamping units 122 to move forward along the trajectory of the "U"-shaped through groove 111 for storage or to move backward for retrieval.

[0031] When using this invention to store shared bicycles, staff only need to move the shared bicycle to the front of the storage platform 110. Two clamping parts 122, located at the front of the adjacent longitudinal openings of the two "U"-shaped channels 111, clamp the two wheels of the shared bicycle. The circulating drive unit 121 drives the clamping parts 122 on the adjacent longitudinal openings of the two "U"-shaped channels 111 to move forward towards the rear of the storage platform 110, thus completing the storage process. During this process, staff do not need to manually move the shared bicycles one by one into the truck and arrange them closely together for mutual support, as is done with traditional truck transport. Furthermore, this invention uses two clamping parts 122 to independently fix the wheels, effectively preventing tipping and damage caused by collisions or instability during movement. When retrieving the shared bicycle, [further details on unrelated steps are needed]. During retrieval, the cyclic drive unit 121 drives the clamping parts 122 on the adjacent longitudinal slots of the two "U"-shaped channels 111 to move in the opposite direction to the front end of the storage platform 110, thereby transporting the shared bicycle to a convenient location for retrieval and completing the retrieval process. The cyclic drive unit 121 can drive the clamping parts 122 on the adjacent longitudinal slots of the two "U"-shaped channels 111 to flow into the opposite longitudinal slots of the two "U"-shaped channels 111 through the transverse slots of the "U"-shaped channels 111, and the cyclic drive unit 121 can also drive the clamping parts 122 on the opposite longitudinal slots of the two "U"-shaped channels 111 to flow into the adjacent longitudinal slots of the two "U"-shaped channels 111 through the transverse slots of the "U"-shaped channels 111, so that the clamping parts 122 circulate within the "U"-shaped channels 111, ensuring that staff can more easily store and retrieve shared bicycles.

[0032] Furthermore, the circulation drive unit 121 includes two longitudinal guides 1211, a transverse connector 1212, and two pushers 1213. The two longitudinal guides 1211 are laid in the storage platform 110 along the two longitudinal slots of the "U"-shaped through groove 111, respectively. The transverse connector 1212 is laid in the storage platform 110 along the transverse slot of the "U"-shaped through groove 111. The two pushers 1213 are both disposed on the storage platform 110 near the transverse slot of the "U"-shaped through groove 111. The output ends of 3 extend into the storage platform 110, and the output ends of the two pushers 1213 push along the two longitudinal slots of the "U"-shaped through groove 111 respectively. Several clamping parts 122 are distributed at intervals above the longitudinal guide 1211 and the transverse connector 1212. The pusher 1213 is used to push the clamping parts 122 above the transverse connector 1212 into the longitudinal guide 1211, so that the longitudinal guide 1211 and the transverse connector 1212 jointly drive the clamping parts 122 to move along the trajectory of the "U"-shaped through groove 111.

[0033] In this invention, the longitudinal guide 1211 and the transverse connecting member 1212 can both be double-speed chains or conveying rollers in the prior art, and the pusher 1213 can be a telescopic cylinder.

[0034] Specifically, when using this invention to store shared bicycles, the flow direction of the clamping part 122 driven by the circulating drive unit 121 on the "U"-shaped through groove 111 is as follows: the longitudinal guide 1211 on the longitudinal slots of the two "U"-shaped through grooves 111 facing away from each other drives the clamping part 122 into the transverse connector 1212. The transverse connector 1212 drives the clamping part 122 to the front end of the longitudinal guide 1211 on the adjacent longitudinal slots of the two "U"-shaped through grooves 111. The pusher 1213 pushes the clamping part 122 on the transverse connector 1212 into the longitudinal guide 1211 on the adjacent longitudinal slots of the two "U"-shaped through grooves 111. The longitudinal guide 1211 on the adjacent longitudinal slots of the two "U"-shaped through grooves 111 drives the clamping part 122 to move forward towards the rear end of the storage platform 110, thus completing the storage. When retrieving shared bicycles from the storage, the longitudinal guide 1211 on the adjacent longitudinal slots of the two "U"-shaped through grooves 111 moves forward towards the rear end of the storage platform 110. The longitudinal guide 1211 on the slot drives the clamping part 122 to move in the opposite direction to the front end of the storage platform 110. After the clamping part 122 transports the shared bicycle to a convenient location and unloads it, the longitudinal guide 1211 on the adjacent longitudinal slots of the two "U"-shaped through slots 111 drives the clamping part 122 to flow into the transverse connector 1212. The transverse connector 1212 drives the clamping part 122 to flow towards the two "U"-shaped through slots 111 in opposite directions. At the front end of the longitudinal guide 1211 on the slot, the pusher 1213 pushes the clamping part 122 on the transverse connector 1212 into the longitudinal guide 1211 on the longitudinal slot with two U-shaped through slots 111 facing away from each other. The longitudinal guide 1211 on the longitudinal slot with two U-shaped through slots 111 facing away from each other drives the clamping part 122 to move towards the rear end of the storage platform 110 for storage, so that the clamping part 122 circulates in the U-shaped through slots 111.

[0035] Furthermore, the cycle drive unit 121 also includes two limiting blocks 1214. The two limiting blocks 1214 are respectively disposed on one end of the two longitudinal guides 1211 near the transverse connector 1212. The limiting blocks 1214 are used to intercept and position the clamping parts 122 on the longitudinal guides 1211 so that the two clamping parts 122 at the front end of the two longitudinal guides 1211 are facing each other. This ensures that there is always one and only one pair of ready clamping parts 122 waiting to work at the front end of the longitudinal guides 1211, while ensuring that the two facing clamping parts 122 clamp a shared bicycle as a group, preventing clamping inconvenience caused by the asynchronous position of the two clamping parts 122.

[0036] Furthermore, four through holes 112 are formed at the bottom of the storage platform 110. The four through holes 112 are correspondingly set on the four longitudinal guides 1211 near one end of the transverse connector 1212. The limiting stop 1214 includes a first drive motor 12141, a guide sleeve 12142, and a lifting rack 12143. The first drive motor 12141 is installed inside the storage platform 110 and is located on one side of the through hole 112. The guide sleeve 12142 is vertically connected to the bottom of the storage platform 110. The guide sleeve 12142 is positioned on the through hole 112. One end of the lifting rack 12143 meshes with the output end of the first drive motor 12141. The other end of the lifting rack 12143 extends into the guide sleeve 12142 through the through hole 112. The first drive motor 12141 drives the lifting rack 12143 to move up and down within the guide sleeve 12142, so that the top end of the lifting rack 12143 rises and intercepts or lowers the clamping part 122 on the longitudinal guide member 1211 to release the interception.

[0037] Furthermore, each cycle drive unit 121 also includes a first photoelectric switch 1215, a second photoelectric switch 1216, a third photoelectric switch 1217, and a fourth photoelectric switch 1218. The first photoelectric switch 1215 is disposed on one side of the adjacent longitudinal slots of the two "U"-shaped through slots, and is located between the limiting stop 1214 and the transverse connecting member 1212. The first photoelectric switch 1215 is used to control the limiting stop 1214 on the adjacent longitudinal slots of the two "U"-shaped through slots 111 to intercept the clamping part 122. The second photoelectric switch 1216 is disposed on the opposite side of the longitudinal slots of the two "U"-shaped through slots 111, and is located on the limiting stop 1214. Between the transverse connecting member 1212, the second photoelectric switch 1216 is used to control the limiting block 1214 of the two U-shaped through slots 111 facing away from each other to intercept the clamping part 122. The third photoelectric switch 1217 and the fourth photoelectric switch 1218 are respectively disposed on the two pushers 1213. The third photoelectric switch 1217 and the fourth photoelectric switch 1218 are used to control the two pushers 1213 to push the clamping part 122. The third photoelectric switch 1217 is disposed on the pusher 1213 at the front end of the adjacent longitudinal slots of the two U-shaped through slots 111, and the fourth photoelectric switch 1218 is disposed on the pusher 1213 at the front end of the longitudinal slots of the two U-shaped through slots 111 facing away from each other.

[0038] Specifically, when using this invention to store shared bicycles, the flow direction of the clamping part 122 on the "U"-shaped through groove 111 is as follows: the clamping part 122 on the longitudinal slots of the two "U"-shaped through grooves 111 facing away from each other flows into the adjacent longitudinal slots of the two "U"-shaped through grooves 111 through the transverse slots of the "U"-shaped through grooves 111. The second photoelectric switch 1216 and the third photoelectric switch 1217 are activated, the first photoelectric switch 1215 and the fourth photoelectric switch 1218 are deactivated, and the second photoelectric switch 1216 detects... When the flow passes through the clamping part 122, the second photoelectric switch 1216 controls the limiting block 1214 at the front end of the two opposing longitudinal slots 111 of the "U"-shaped through-slots to descend and release the clamping part 122, thereby ensuring that the clamping part 122 at the rear end of the two opposing longitudinal slots 111 of the "U"-shaped through-slots 111 can flow sequentially to the front end. When the third photoelectric switch 1217 detects the clamping part 122, the third photoelectric switch 1217 controls the pusher 1213 to push the clamping part 122 into the two opposing longitudinal slots 111. When a shared bicycle is retrieved from the warehouse, the flow direction of the clamping part 122 on the "U"-shaped through-slot 111 is as follows: the clamping parts 122 on the adjacent longitudinal slots of the two "U"-shaped through-slots 111 flow through the transverse slots of the "U"-shaped through-slots 111 into the opposite longitudinal slots of the two "U"-shaped through-slots 111. The first photoelectric switch 1215 and the fourth photoelectric switch 1218 are activated, the second photoelectric switch 1216 and the third photoelectric switch 1217 are deactivated, and the first photoelectric switch 1215 detects the clamping. When the flow passes through part 122, the first photoelectric switch 1215 controls the limiting block 1214 on the adjacent longitudinal slots of the two "U"-shaped through slots 111 to descend and release the intercepting clamping part 122, thereby ensuring that the clamping part 122 at the rear end of the adjacent longitudinal slots of the two "U"-shaped through slots 111 can flow sequentially to the front end. When the fourth photoelectric switch 1218 detects the clamping part 122, the fourth photoelectric switch 1218 controls the pusher 1213 to push the clamping part 122 into the opposite longitudinal slots of the two "U"-shaped through slots 111.

[0039] Furthermore, each clamping part 122 includes a movable support base 1221, a second drive motor 1222, and a gripper 1223. The movable support base 1221 is located between the cyclic drive unit 121 and the upper plate of the storage platform 110. The cyclic drive unit 121 drives the movable support base 1221 to move along the trajectory of the "U"-shaped through groove 111. The second drive motor 1222 is located inside the movable support base 1221. The gripper 1223 is located on both sides of the movable support base 1221. One end of the gripper 1223 is rotatably connected to the movable support base 1221, and the other end of the gripper 1223 extends out of the storage platform 110 through the "U"-shaped through groove 111. The output end of the second drive motor 1222 is connected to the middle of the gripper 1223. The second drive motor 1222 drives the gripper 1223 to close or open, so that the gripper 1223 clamps the wheel of the shared bicycle.

[0040] Furthermore, the upper part of the movable support base 1221 has a boss 12211. The width of the boss 12211 is adapted to the width of the longitudinal groove of the "U"-shaped through groove 111, and the length of the boss 12211 is adapted to the width of the transverse groove of the "U"-shaped through groove 111. The boss 12211 extends out of the "U"-shaped through groove 111 and abuts against the groove edge of the "U"-shaped through groove 111, so that the boss 12211 guides the movable support base 1221 to move along the trajectory of the "U"-shaped through groove 111.

[0041] Furthermore, the gripper 1223 includes two rocker arms 12231, a connecting block 12232, and two sets of connecting plates 12233. One rocker arm 12231 is located at the front end of the movable support base 1221, and the other rocker arm 12231 is located at the rear end of the movable support base 1221. The bottom ends of both rocker arms 12231 are hinged to the movable support base 1221 by pins. The connecting block 12232 is located above the movable support base 1221 and between the two rocker arms 12231. One end of each set of connecting plates 12233 is connected to both sides of the connecting block 12232 via... The two sets of connecting plates 12233 are hinged together by pins. The other ends of the two sets of connecting plates 12233 are respectively hinged to the middle of the two rocker arms 12231 by pins. The two connecting plates 12233 are a set, and the two connecting plates 12233 are respectively located on both sides of the rocker arms 12231. The output end of the second drive motor 1222 is fixedly connected to the middle of the connecting block 12232. The second drive motor 1222 drives the connecting block 12232 to rise or fall. The connecting block 12232 drives the two rocker arms 12231 to rotate towards each other to clamp and close, or to rotate away from each other to open and release.

[0042] Furthermore, wheel contour grooves 122311 are provided on the upper opposite surfaces of the two rocker arms 12231. When the two rocker arms 12231 rotate toward each other to clamp and close, the tire of the shared bicycle can be embedded in the wheel contour grooves 122311, preventing the vehicle from lurching forward or backward or sliding left or right due to shaking, thus eliminating the risk of the shared bicycle tipping over.

[0043] On the other hand, please see Figure 6 The present invention also provides a storage and retrieval vehicle 20, which includes the shared bicycle placement device 10 described in the previous aspect.

[0044] Specifically, the storage vehicle 20 also includes a support frame 210 and a cleaning component 220. The support frame 210 is mounted on the storage platform 110 and has an opening at its front end so that the support frame 210 and the upper surface of the storage platform 110 together form a box-type storage area. The cleaning component 220 is located on the upper part of the support frame 210 and is used to spray cleaning fluid into the box-type storage area formed by the support frame 210 and the upper surface of the storage platform 110 to clean the shared bicycles on the storage platform 110.

[0045] In a preferred embodiment, the cleaning assembly 220 includes a water tank 221 and a plurality of spray heads 222. The water tank 221 is disposed on the top of the support frame 210, and the plurality of spray heads 222 are evenly connected to the bottom of the water tank 221. The water tank 221 stores cleaning fluid, and the plurality of spray heads 222 spray cleaning fluid onto the box-shaped storage area formed by the support frame 210 and the upper surface of the storage platform 110, thereby cleaning the shared bicycles stored on the storage platform 110.

[0046] In a preferred embodiment, the storage vehicle 20 further includes a moving component 230, which is disposed at the bottom of the storage platform 110. The moving component 230 is used to drive the storage platform 110 to move and transfer. The moving component 230 includes an "L"-shaped support plate 231, a third drive motor 232, and Mecanum wheels 233. There are four "L"-shaped support plates 231. The number of third drive motors 232 and Mecanum wheels 233 is the same as the number of "L"-shaped support plates 231. The four "L"-shaped support plates 231 are respectively located at the four corners of the storage platform 110. The four third drive motors 232 are respectively located on the four "L"-shaped support plates 231. The "L"-shaped support plates 231 are detachably connected to the storage platform 110 by bolts. The "L"-shaped support plates 231 are detachably connected to the third drive motors 232 by bolts. The output shaft of the third drive motor 232 is connected to the axis of the Mecanum wheel 233.

[0047] In this invention, the Mecanum wheel 233 is existing technology. The Mecanum wheel 233 has a hub + roller structure, where the hub is the main support, and multiple drum-shaped rollers are obliquely distributed on the rim. The roller axis forms a 45-degree angle with the hub axis, and the generatrix envelope of the roller is a cylindrical surface, ensuring continuous rolling of the wheel while allowing lateral slippage. The motion synthesis mechanism of the Mecanum wheel 233 is that each roller can rotate independently. By adjusting the speed and direction of each wheel, the friction force is decomposed into lateral and longitudinal components, and finally synthesized into a resultant force vector in any direction. A typical four-wheel combination (left-hand and right-hand wheels are mirror-symmetrical) is independently driven by a motor, which can control the vehicle to achieve omnidirectional movement such as translation, diagonal movement, and rotation. It is a special wheel structure that can achieve omnidirectional movement.

[0048] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
