Description

Technical Field

[0001] The utility model belongs to the technical field of parking equipment and relates to a parking garage, in particular to a double-layer parking garage for electric bicycles. Background Art

[0002] With the rapid growth in the number of electric bicycles, their parking management has become a major challenge in the fields of urban transportation and public safety.

[0003] In order to adapt to the development of society, three-dimensional parking garages have appeared in the prior art, which solve the problems of insufficient outdoor parking spaces and random parking by adding parking spaces in a three-dimensional space.

[0004] For example, a Chinese patent with publication number CN106760715B discloses a lifting double-layer parking rack, which includes a column, an upper parking rack, a lifting actuator arranged on the column for lifting the upper parking rack, a transverse guide rail perpendicular to the column, a lower parking rack slidably arranged on the transverse guide rail, and a transverse actuator for driving the lower parking rack to slide along the transverse guide rail; the upper parking rack is provided with an upper horizontal slide groove for supporting a bicycle, the length direction of the upper horizontal slide groove is perpendicular to the transverse guide rail, and the front end of the upper horizontal slide groove is an upper wheel opening for the bicycle wheels to enter; the lower parking rack is provided with a lower horizontal slide groove for supporting a bicycle, the length direction of the lower horizontal slide groove is perpendicular to the transverse guide rail, and the front end of the lower horizontal slide groove is a lower wheel opening for the bicycle wheels to enter.

[0005] Another example is a Chinese patent with publication number CN109356422B that discloses a small double-layer three-dimensional parking device for electric bicycles. The device is divided into several parking units, and each group of parking units is divided into two layers, the lower parking platform can move horizontally, and the upper parking platform can move up and down. When parking or picking up a vehicle on the upper layer, the lower parking platform is moved horizontally to vacate the space directly below the upper parking platform of the vehicle to be parked, and the upper parking platform of the vehicle to be parked is pulled down. After the vehicle is parked or picked up, the upper parking platform is raised and reset. The device has a simple and compact structure, quick and convenient operation, low manufacturing cost, and small space occupation, which is easy to promote and use. The upper and lower parking platforms are also provided with front and rear wheel clamping mechanisms for fixing the front and rear wheels of the electric bicycle, so that the vehicle can be parked more stably and reliably, and is safer to use.

[0006] As can be seen from the above patents, in the prior art, after a bicycle is fixed, its front and rear wheels are both in the same straight line with the vehicle body. However, this parking method is not conducive to the stability of bicycle parking. Since the upper parking rack needs to perform lifting movement during use, in order to ensure the stability of bicycle parking, the patent with the publication number CN106760715B provides a clamping mechanism for fixing the bicycle; the patent with the publication number CN109356422B is a garage design for electric bicycles. Due to the large self-weight and small wheels of electric bicycles, in order to ensure their parking stability, this patent provides a front and rear wheel clamping mechanism for clamping the front and rear wheels of the electric bicycle. However, in either case, the vehicle needs to be parked in place first, and then the clamping mechanism is activated, which not only makes the operation cumbersome, but also makes the structure of the entire garage relatively complex. Moreover, once foreign objects such as stones adhere to the clamping jaws of the clamping mechanism or the tires of the wheels, they will cause damage to the tires of the wheels during the clamping operation, shortening the service life of the tires. Summary of the Invention

[0029] The advantages and positive effects of the present utility model are:

[0030] 1. For this double-deck parking garage for electric bicycles, the design of directly clamping the bicycle parked straight by the existing method is changed to the design of driving the front wheel of the bicycle to deflect through the deflection of the front-wheel fixing groove. When the front wheel deflects, its wheel surface will tilt downward. The left and right sides of the front wheel abut against the inner wall of the front moving and rotating groove. Coupled with the contact point between the front wheel and the bottom of the front moving and rotating groove, these three points form a stable triangular support structure, so that the front wheel is stably limited. At the same time, any two points of the front wheel and the rear wheel form a stable triangular structure, further improving the stability of the overall parking of the electric bicycle.

[0031] This double-deck parking garage for electric bicycles is easy to operate and does not require instructions for the user. The electric bicycle can be directly pushed into the parking space.

[0032] Meanwhile, through this front-wheel deflection parking method, the handlebar can be deflected, reducing the required parking width, that is, the width of the parking space. With the same parking width, this front-wheel deflection parking method can increase the parking quantity by 30% compared to the traditional parking method where the front and rear wheels are in a straight line.

[0033] 2. This double-layer parking garage for electric bicycles can achieve the automatic translation of the lower-layer parking space and the automatic lifting of the upper-layer parking space, greatly reducing the labor intensity of manual operation and facilitating the use of users.

[0034] 3. This double-layer parking garage for electric bicycles, through the setting of the charging mechanism, meets people's needs for charging electric bicycles and achieves the purpose of safe and reliable charging.

[0035] 4. The design of this utility model is scientific and reasonable, with the advantages of convenient operation, simple structure, strong parking stability, and easy implementation. It is a double-layer parking garage for electric bicycles with high innovation. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0052] The following further details the embodiments of the present utility model with reference to the accompanying drawings:

[0053] A double - layer parking garage for electric bicycles, its innovation lies in: including longitudinal guide rail columns 1, transverse translation guide rails 4, longitudinal lifting mechanisms 2 for parking spaces, transverse translation mechanisms 5 for parking spaces, upper - layer parking spaces 3 and lower - layer parking spaces 6. At the rear of the transverse translation guide rails, longitudinally spaced and evenly distributed longitudinal guide rail columns are connected. On each longitudinal guide rail column, an upper - layer parking space is driven and installed by a longitudinal lifting mechanism for the parking space. On each transverse translation guide rail, a lower - layer parking space is driven and installed by a transverse translation mechanism for the parking space. As Figure 1 shown, there are 3 upper - layer parking spaces and 2 lower - layer parking spaces.

[0054] This double - layer parking garage for electric bicycles can realize the double - layer parking of electric bicycles, greatly increasing the parking quantity of electric bicycles and reducing the occupation of ground resources.

[0055] The longitudinal guide rail column includes a column body and longitudinal guide grooves 10. On the front end face of the column body, two longitudinal long holes 9 are symmetrically arranged. On both sides of the column body, longitudinal guide grooves are symmetrically arranged.

[0056] The longitudinal lifting mechanism for the parking space includes a double - output reduction motor 8, sprockets, transmission chains (not shown in the figure), chain connection plates 11, counterweight plates 12 and an upper - layer parking space lifting connection frame. At the top of the longitudinal guide rail column, a double - output reduction motor is installed through a motor fixing plate 7. The output shafts of the double - output reduction motor are rotatably installed on the two side walls of the longitudinal guide rail column through bearings. Sprockets are installed at both ends of the output shafts. Transmission chains are meshed and wound on the sprockets. One end of the transmission chain is connected to the chain connection plate, and the other end is connected to the counterweight plate. On the chain connection plate, two rows of forward - extending connection claws 16 are arranged. The connection claws extend out through the long holes and are connected to the upper - layer parking space lifting connection frame;

[0057] The upper - layer parking space lifting connection frame includes an upper - layer front connection groove 15, an upper - layer rear connection groove 13, a parking space connection plate 18 and a connection claw fixing block 17. At the upper - end back of the upper - layer front connection groove, the upper - layer rear connection groove is welded. Longitudinal guide wheels 14 are installed on the two side plates of the upper - layer rear connection groove. Each longitudinal guide wheel slides in the longitudinal guide groove, enhancing the stability of the lifting of the upper - layer parking space. On the upper - layer rear connection groove, a connection claw fixing block for fixing the connection claws is welded. At the lower front end of the upper - layer front connection groove, a parking space connection plate is horizontally welded. The upper - layer parking space is connected to the parking space connection plate; To ensure the aesthetics and practicality of the product, a decorative plate is installed at the front end of the upper - layer front connection groove. The lower half of the upper - layer front connection groove is longer than the height of the transverse translation guide rail. The distance between the rear end face of the upper - layer parking space and the front end face of the longitudinal guide rail column is greater than the width of the transverse translation guide rail to ensure that the upper - layer parking space can land smoothly when descending.

[0058] A switch 45 connected to the dual-output reduction motor through a signal wire is installed on the front side of the upper parking space. This switch is used to control the up and down movement of the upper parking space.

[0059] The lateral translation guide rail includes a guide rail body 23, an upper guide groove 27, and a lower guide groove 30. The guide rail body is a structure formed by integral bending. It includes a middle vertical part, a first horizontal part, two front vertical parts on both sides, a second horizontal part, and two rear vertical parts on both sides. At both ends of the middle vertical part, a first horizontal part is bent forward horizontally. At the ends of the two first horizontal parts, two front vertical parts on both sides are bent vertically outwards. At the ends of the two front vertical parts on both sides, a second horizontal part is bent backward horizontally. At the ends of the two second horizontal parts, two rear vertical parts on both sides are bent vertically inwards;

[0060] The upper guide groove and the lower guide groove are respectively installed on the second horizontal parts at the upper and lower ends.

[0061] The parking space lateral translation mechanism includes a reduction motor 31, a driving gear 29, a rack 24, and a lower parking space translation connecting frame. A rack is installed on the first horizontal part located below, and a driving gear is meshed and installed on the rack. This driving gear is driven by a reduction motor installed on the lower parking space translation connecting frame;

[0062] The lower parking space translation connecting frame includes a lower front connecting groove 32, a lower rear connecting groove 21, and a parking space connecting plate. The lower rear connecting groove is welded to the back of the lower front connecting groove. Lateral guide wheels 28 are installed on the upper and lower side plates of the lower rear connecting groove. Each lateral guide wheel slides in the upper guide groove and the lower guide groove respectively. A reduction motor is installed on the upper front part of the lower front connecting groove. To ensure the safety of the reduction motor, a protective cover 22 with heat dissipation holes is installed at the front end of the reduction motor. The output shaft of the reduction motor passes through the lower front connecting groove and the lower rear connecting groove and is drivingly connected to the driving gear. A parking space connecting plate is horizontally welded to the lower front part of the lower front connecting groove. A lower parking space is connected to the parking space connecting plate;

[0063] A switch connected to the reduction motor through a signal wire is provided on the front side of the lower parking space. This switch is used to control the lateral translation of the lower parking space. When this switch is pressed, under the action of the reduction motor, the lateral movement of the lower parking space is realized to make way for the upper parking space to descend.

[0064] When the lower parking space is full and it is necessary to park on the upper parking space, first trigger the switch of the lower parking space to move it away, and then trigger the switch of the upper parking space above it to make it descend. After parking the car, trigger the switch on the upper parking space again to make it rise.

[0065] The present utility model also provides another way for the lower parking space to give way when parking in the upper parking space: that is, on the middle vertical part of the movable transverse trough beam, a photoelectric switch is arranged at a position corresponding to the middle part of the longitudinal guide rail column. The photoelectric switch is used to detect whether there is a lower parking space on this parking space and send a signal to the reduction motor.

[0066] During operation, the user triggers the switch of the upper parking space to lower the upper parking space. At the same time, the photoelectric switch detects whether there is a lower parking space on this parking space. If there is a lower parking space at this position, it sends a signal to the reduction motor to automatically move it away. At this time, the upper parking space descends in place. After parking the car, trigger the switch on the upper parking space again to make it rise.

[0067] The two ways of parking in the upper parking space can be set separately or simultaneously. When set simultaneously, it mainly relies on the detection of the photoelectric switch and the automatic way of giving way. When its operation fails or a fault occurs, then use the first manual operation method.

[0068] In order to avoid the problem of collision when the lower parking space moves horizontally, the present utility model also designs a travel switch limit rod 20 and a travel switch 19. On both sides of the front connecting groove of the lower layer, travel switch limit rods extending horizontally outward are symmetrically installed. A limit switch is embedded at the end of one travel switch limit rod, and a rubber pad is installed at the end of the travel switch limit rod on the other side. When the travel switch on the moving lower parking space detects the adjacent lower parking space, the moving lower parking space stops moving.

[0069] Both the upper parking space and the lower parking space include a connecting groove 33 with an opening facing forward, a base, a front wheel sliding assembly, and a rear wheel parking rack 46. The base includes a bottom plate 34, side baffles 36, additional front baffles 55, a chute 52, and a cable pipe 53. Additional front baffles and connecting grooves are respectively installed at the front and rear ends of the bottom plate. The back of the connecting groove is connected to the parking space connecting plate on the longitudinal lifting mechanism and the transverse translation mechanism of the parking space through angle steel. Side baffles are symmetrically installed on both sides of the bottom plate. A chute and a cable pipe are arranged on the bottom plate. The chute includes a front end centered horizontal section, an inclined section, and a rear end side horizontal section. A front end centered horizontal section is arranged at the center of the front end of the bottom plate along its length direction. An inclined section inclined to the side is butted at the rear end of the front end centered horizontal section. A rear end side horizontal section located at the side of the bottom plate is butted at the rear end of the inclined section. A rear wheel parking rack is installed between the two side baffles at the front end of the additional front baffle;

[0070] The described front-wheel sliding assembly includes a horizontal sliding plate 40, a front-wheel fixing groove 39, a front moving and rotating groove 41, a guiding guardrail 44, a sliding plate limiting assembly, side guiding wheels, and a wheel guiding assembly 51. Side guiding wheels are installed at intervals on both sides of the horizontal sliding plate. Each side guiding wheel moves within a transverse guiding groove 37 provided inside the side baffle. A front-wheel fixing groove is rotatably installed at the upper end of the horizontal sliding plate through the wheel guiding assembly. The wheel guiding assembly moves within a sliding groove. A front moving and rotating groove is hinged to the front end of the front-wheel fixing groove through a pin shaft with a torsion spring inserted. Guiding guardrails are symmetrically installed on both sides of the horizontal sliding plate at the front end of the front moving and rotating groove. The two guiding guardrails form a guiding structure with a larger opening at the front end and a smaller opening at the rear end. The wheel guiding assembly includes a bearing 60, a swing rod 58, a rotating shaft 59, and a front-wheel guiding wheel 57. A bearing is installed on the horizontal sliding plate. A rotating shaft is installed inside the bearing. The upper end of the rotating shaft is fixedly installed at the bottom of the front-wheel fixing groove. The lower end of the rotating shaft is fixedly installed with a horizontally arranged swing rod. A front-wheel guiding wheel that moves within the sliding groove is installed on the swing rod through a connecting shaft.

[0071] In the initial state, the notch of the front moving and rotating groove faces forward. As the front wheel of the electric bicycle moves backward along the guiding structure, the front end of the front wheel is placed inside the front-wheel fixing groove, and the front moving and rotating groove flips backward and buckles on the rear end face of the front wheel, completing the front and rear limit of the front wheel.

[0072] Meanwhile, as the wheel guiding assembly moves within the sliding groove, the front-wheel fixing groove connected to the wheel guiding assembly rotates. When the wheel guiding assembly moves to the rear side horizontal section of the sliding groove, that is, after the electric bicycle is parked in place, the front wheel of the electric bicycle is in a deflected state, and while the front wheel is deflected, its wheel surface is in a downward inclined state. The left and right sides of the front wheel abut against the inner wall of the front moving and rotating groove. Coupled with the contact point between the front wheel and the bottom of the front moving and rotating groove, the three points form a stable triangular support structure, enabling the front wheel to be stably limited. At the same time, any two points of the front wheel and the rear wheel form a stable triangular structure, further improving the stability of the overall electric bicycle during parking.

[0073] To facilitate the smooth entry of the front wheel of the electric bicycle into the front wheel fixing groove, it is necessary to fix the horizontal sliding plate. The sliding plate limiting component of the present utility model plays the role of limiting the horizontal sliding plate. The sliding plate limiting component includes a limiting rod 42 and a limiting block 43. The limiting block is installed at a position closer to the front on the upper end surface of the side baffle, and a limiting rod extending horizontally to both sides is installed at the front end of the front moving rotation groove. The limiting rod realizes the limit of the front wheel sliding component by hooking the front end of the limiting block. After the wheel is pressed into the front moving rotation groove, the front moving rotation groove twists under the action of the torsion spring. At this time, the limiting rod installed on it lifts upward, so as to achieve the purpose of unlocking, and then push the electric bicycle backward. With the cooperation of the front wheel sliding component and the sliding groove, the front and rear wheels of the electric bicycle are misaligned, enhancing the stability of the placement.

[0074] The rear wheel parking rack includes an inverted trapezoidal groove and a rear wheel limiting groove. An inverted trapezoidal groove is installed between the two side baffles at the front end of the additional front baffle.

A rear wheel limiting groove is installed at the front end inside the notch 50 of the inverted trapezoidal groove. The rear wheel limiting groove includes a fixed part 48 fixed at the front end of the notch of the inverted trapezoidal groove and a rotating part 49 hinged at the rear end of the fixed part through a pin shaft with a torsion spring installed. The vertical plate of the rotating part is inclined backward.

[0075] When the electric bicycle is pushed backward in place, its rear wheel falls into the rear wheel limiting groove, and the rotating part plays the role of supporting the rear wheel under the action of the torsion spring.

[0076] To avoid the situation of accidental collision when someone is at the bottom during the descent of the upper parking space, an induction bottom plate 35 is installed at the bottom of the upper parking space. A rubber bottom foot 47 is installed at the front end of the bottom of the induction bottom plate. The induction bottom plate is a structure in which pressure sensors 54 are encapsulated at intervals inside a hollow plate body. The pressure sensors in this embodiment are pressure sensors with a specification of 50 kg. When the pressure sensors sense a pressure of 200 - 300 g, they will send signals to the double-output reduction motor, and the upper parking space stops moving.

[0077] Horizontal limiting legs 25 extending horizontally are symmetrically installed on both sides at the front end of the lower parking space. Rubber pads are installed at the ends of the limiting legs, and traveling wheels 26 are installed at the lower part of the limiting legs. It is convenient for the movement of the lower parking space.
