The operating system of the garage is a semi-automatic system, the bicycle is put in storage for manual propulsion, and other actions are electric drive. The garage is mainly applied to greening places and leisure places of the cells, on one hand, considering that the garage frame is round, the height of the garage is only about 1.5m, greening can be carried out on the garage frame and the periphery of the garage frame, the garage frame is similar to a flower bed of the cells, the garage frame can be conveniently arranged near the central leisure area of the cells and the greening belts of the cells, and leisure chairs and the like can be arranged around the garage frame; on the other hand, the actual state of the garage shell can be subjected to process design along with the environment of the district, thereby meeting the requirement of beautiful appearance and even becoming a sign of the district.

The garage comprises a chassis 50 and a garage shell 60 positioned on the chassis 50, wherein the chassis 50 is fixed on a foundation to bear the whole garage; the garage includes a control module 10, a rotary module 20, a garage door module 30, and a stationary module 40. The rotating module 20, the garage door module 30, and the stationary module 40 are electrically connected to the control module 10.

As shown in fig. 2, the rotation module 20 includes a turntable 21, a main shaft 22, a pulley mechanism 23, a rolling bearing 24, a large bevel gear 25, a coupling 26, a small bevel gear 27, an intermediate shaft 28, a vertical bearing housing 29, and a first motor 291. The turntable 21 is arranged above the chassis 50 and is fixedly connected with the chassis through the main shaft 22. The main shaft 22 passes through the chassis 50 and is connected with the chassis 50 through the rolling bearing 24 (located below the chassis 50), the upper end of the main shaft 22 is fixedly connected with the turntable 21, and the lower end of the main shaft passes through the chassis 50 and is sequentially connected with the rolling bearing 24 and the large bevel gear 25. The pulley mechanism 23 is disposed between the turntable 21 and the chassis 50, and is used for supporting the turntable 21 to ensure smooth rotation, and the pulley at the bottom is fixed on the chassis 50, and the pulley at the top rotates along with the turntable 21. The vertical bearing seat 29 is arranged below the chassis 50, one end of the vertical bearing seat 29 is fixed below the chassis 50, the other end of the vertical bearing seat is used for fixing the intermediate shaft 28, one end of the intermediate shaft 28 passes through the vertical bearing seat 29 to rest on the vertical bearing seat 29, the other end of the intermediate shaft is connected with the first motor 291 through the coupling 26, and a small bevel gear 27 meshed with the large bevel gear 25 is arranged in the middle of the intermediate shaft.

The rotating module 20 is disposed below the garage, and the rotation of the first motor 291 is driven to the main shaft 22 by a pair of reduction bevel gears (i.e., the large bevel gear 25 and the small bevel gear 27), so as to drive the turntable 21 to rotate, so as to realize the function of converting parking spaces in the working process of the garage. Considering the transmission part, the rotation of the main shaft 22 requires a power source to provide a large starting moment and power due to the weight of the bicycle itself and the power requirements of mechanical elements, and meanwhile, certain requirements on motion stability are met. Bevel gear transmission, which is used for transmission between intersecting shafts, and the transmission efficiency is generally 0.94-0.98; the bevel gear has stable transmission operation and higher gear bearing capacity. Therefore, in view of the foundation engineering and the motor working environment, the intermediate shaft 28 and the main shaft 22 are preferably arranged to be in crossed shaft transmission, and the requirements of motion stability, safety and the like are added, so that bevel gear transmission is preferred. The selected transmission scheme is as follows: the drive 13-the first motor 291-the coupling 6-the bevel gears 5, 7-the main shaft 2. To increase the efficiency of the work system, after a parking space is selected, the turntable 21 rotates the selected parking space to the garage door 33 on a near basis, i.e., by as small an angle as possible.

As shown in fig. 3, the garage door module 30 includes an arc-shaped sliding rail 31, a first pulley 32, a garage door 33, a second pulley 34, an arc-shaped sliding groove 35, a swing link mechanism 36, a motor shaft 37, and a second motor 38, wherein one end of the swing link mechanism 36 is installed inside the garage door 33, the other end is connected with the motor shaft 37, and the second motor 38 is connected with the motor shaft 37 and provides rotational power for the garage door module 30. The garage door 33 is mounted and positioned by the arcuate slide rail 31 and the first pulley 32 to ensure movement thereof in the arcuate chute 35. The movement and fixing of the garage door 33 is achieved by pulleys (i.e., the first pulley 32 and the second pulley 34), the second pulley 34 is combined with the arc chute 35 at the bottom, and the first pulley 32 is combined with the arc chute 31 at the top, so that the four directions of freedom of the garage door 33 are limited, and the garage door can only move along the arc chute 31 and the arc chute 35, and preferably, the first pulley 32 is a V-shaped groove pulley.

To match the garage profile, the garage door 33 is designed as an arcuate door that conforms to the overall perimeter (e.g., door width 1.2 m). The garage door 33 extends a distance (e.g., 0.3 m) from the top of the garage toward the center, taking into account the viewing angle of the vehicle being accessed. The second motor 38 drives the swing rod mechanism 36 through the motor shaft 37, the sliding block of the swing rod mechanism 36 is fixedly connected to the garage door 33, and the second motor 38 is controlled to rotate to open/close the door. The garage door 33 has a width slightly wider than the width of the reserved tunnel for protection against rain and dust.

The fixing module 40 is arranged on the turntable 21 and comprises a parking space platform fixing device 42 capable of moving on the turntable 21 and a front wheel clamping device 41 arranged on the parking space platform fixing device 42. As shown in fig. 4, the front wheel clamping device 41 includes an attracting electromagnet 411, a link mechanism 412, a clamping plate 413, a first contact switch 414, and a front barrier 415. The adsorption electromagnet 411 and the first contact switch 414 are both located on the front baffle 415, for example, the first contact switch 414 may be disposed on the front side of the front baffle 415, so that the front wheel of the bicycle touches the first contact switch 414 when the bicycle is accessed. Preferably, the number of the clamping plates 413 is two, and the clamping plates are respectively located at two sides of the front baffle 415. The link mechanism 412 is connected with the clamping plate 413, and the adsorption power provided by the adsorption electromagnet 411 drives the clamping plate 413 hinge via the link mechanism 412, so as to realize clamping and fixing of the front wheel of the bicycle.

As shown in fig. 5, the parking space platform fixing device 42 includes an impact electromagnet 421, a bracket 422, a cylindrical pin 423, a platform positioning hole 424, a parking space platform 425, a guide rail 426, and a second contact switch 427. The parking space platform 425 is mounted (e.g., by screws) on the guide rail 426 and moves with the guide rail 426 to achieve mobile warehouse entry/exit; the guide rail 426 is located on the turntable 21 and rotates with the turntable 21. The parking space platform 425 is provided with a plurality of platform positioning holes 424 for the cylindrical pins 423 to pass through to fix the parking space platform 425. The support 422 is used for supporting the impact electromagnet 421, the cylindrical pin 423 is located below the impact electromagnet 421, and the second contact switch 427 is disposed at the impact electromagnet 421 (the second contact switch 427 is not visible in fig. 5).

Since the main motion of the garage is a rotation motion, the bicycle is easily subject to unstable conditions such as sliding and tilting due to the steering force and centrifugal force during the rotation, and the vehicle is damaged, and for this reason, it is necessary to provide the front wheel clamping device 41. Considering the sealing and viewing angle of the garage, if the front wheel clamping device 41 is fixedly connected in front of the parking space, it is difficult to align the front wheel of the bicycle to achieve clamping, so that the front wheel clamping device 41 is mounted on the parking space platform 425, and the front wheel can be clamped at the door of the garage and then put into storage together with the parking space platform 425. The power is provided by the adsorption force of the adsorption electromagnet 411, and when the power is electrified, adsorption power is generated, the clamping plate 413 hinge is driven by the link mechanism 412, so that the front wheel is clamped and fixed, the front wheel clamping device 41 is fixed on the parking space platform 425, and the adsorption electromagnet 411 is arranged on the rear side of the front baffle 415. Considering the problem of resetting the attraction electromagnet 411 after taking the vehicle, the method can be realized by changing the magnetic pole, and the specific implementation method can be as follows: the full-bridge inverter circuit is composed of four thyristors (which can be replaced by relays) to change the current direction, so that the magnetic poles are changed.

The front wheel clamping device 21 and the front wheel are arranged on the parking space platform 425, and then move along with the parking space platform 425 to enter and leave the garage. From the aspect of the movement process, the whole parking space platform 425 needs to be fixed at two positions, firstly, after the bicycle is put in storage, the parking space platform 425 should be limited at the front end of the parking space (namely the azimuth of the front wheel of the bicycle) and not be moved, otherwise, the parking space platform 425 is in an unstable state, and secondly, after the bicycle is put out of storage, the parking space platform 425 should be limited at the tail end of the parking space (namely the azimuth of the rear wheel of the bicycle or the garage gate) and not be moved, so that the parking space can be used next time. Preferably, a parking space platform fixing device 42 is arranged at the head end and the tail end of the parking space. The impact electromagnet 25 is in a point-type operation, one end of the push head (i.e. the cylindrical pin 423) is used for fixing, when the iron core is pushed forward during power-on, the cylindrical pin 423 rises to leave the platform positioning hole 424, and the parking space platform 21 can move for a certain time (for example, 2 seconds) after losing the limit; when the power is off, the cylindrical pin 423 enters the platform positioning hole 424 and limits the movement of the parking space platform 21 by automatically resetting by the spring.

As shown in fig. 5, the control module 10 includes a control chip 11, an operation keyboard 12, a driver 13, an encoder 14, a relay 15, and an alarm 16, where the operation keyboard 12, the driver 13, the encoder 14, the relay 15, the alarm 16, the first contact switch 414, and the second contact switch 427 are all electrically connected to the control chip 11. The operation keypad 12 is fixed to one side of the garage door 33 to facilitate the operation of a parking person (e.g., inputting an operation command for parking or picking up a car); each motor (including the first motor 291 and the second motor 38) is controlled by the driver 13 and the encoder 14, and the driver 13 and the encoder 14 are matched with each motor for use; the relay 15 is used for realizing sequential control and is arranged in a circuit of each contact switch (comprising the first contact switch 414 and the second contact switch 427); the alarm 16 may be provided on top of the garage housing 60 for alerting when an abnormal condition (for example) occurs during operation of the garage; the first contact switch 414 is disposed at the adsorption electromagnet 411 and provides a signal whether the front wheel is in place; the second contact switch 427 is disposed at the impact electromagnet 421 at the head and tail ends of the parking space, and provides a signal whether the parking space platform 425 needs to move. The control module 10 realizes automatic control of system start, rotation of each motor, signal receiving of a contact switch, opening and closing of the impact electromagnet 25, on-off of the adsorption electromagnet 19 and other movements, thereby completing the actions of system start and closing, garage rotation, garage door opening and closing, on-off of a fixing device and the like.
