Description

Technical Field

[0001] The invention relates to the technical field of bicycle parking devices, and in particular to an indoor bicycle parking device and a parking method. Background Art

[0002] With the development of society, people's awareness of environmental protection and health is gradually improving. More and more people are starting to use bicycles as their daily means of transportation. As a result, there is less and less space for individuals to park bicycles, especially inside communities and homes. Without reasonable parking plans, bicycles are placed randomly, hindering traffic flow and increasing safety hazards.

[0003] Traditional bicycle parking methods mostly adopt horizontal placement. Although this method is simple and direct, it occupies a large area and has low space utilization, especially when indoor space is limited, it is difficult to meet the parking needs of a large number of bicycles. In order to solve this problem, some devices for vertically parking bicycles have appeared on the market. For example, the utility model patent with publication number CN219969861U disclosed a bicycle parking device that can be vertically lifted and locked on November 7, 2023. The horizontal sliding device is fixed to the ground; the horizontal sliding device is connected to the rear wheel fixing device for the rear wheel to slide forward and fix the rear wheel; the locking device is installed on the inside of the horizontal sliding device for wheel locking; the vertical sliding device corresponds to the front part of the bicycle and is connected to the front wheel fixing device for the front wheel to slide vertically and fix the front wheel; the horizontal sliding device is then connected to the vertical sliding device by a shaft coupling device, so that the rear wheel is pushed forward while driving the front wheel to slide vertically.

[0004] These devices drive the horizontal sliding rack and gear to move by pushing the bicycle, thereby realizing the vertical parking of the bicycle. However, this design has many shortcomings in practical applications.

[0005] First, due to individual differences in user strength, operating habits, etc., pushing a bicycle to park vertically often requires great strength and skills, which makes some users feel inconvenient when operating. Secondly, traditional devices often use U-shaped fixing structures and round steel pipes to fix bicycle wheels. This design can easily cause the wheels to shift during the lifting process of the bicycle, which in turn causes the bicycle to shake, which not only affects the stability of parking, but may also threaten the stability of the device itself and reduce its service life. Summary of the invention

[0016] A current Hall sensor is arranged in the mounting seat, and the current Hall sensor is electrically connected to the reduction motor and is used for current change, and whether the movement of the synchronous belt is obstructed is judged by the current change.

[0017] A limit block is fixedly provided on the side of the horizontal pulley track, one side of the limit block is connected to a magnet, and the first clamping mechanism is connected to a magnetic attraction plate, and the magnetic attraction plate is magnetically matched with the magnet.

[0019] S1, placing the front and rear wheels of the bicycle above the horizontal pulley track;

[0020] S2, slidingly displacing the first clamping mechanism to the position of the rear wheel of the bicycle, so that the two clamping claws of the first clamping mechanism clamp the inner side of the rear wheel rim of the bicycle;

[0021] The second clamping mechanism is slidably displaced to the front wheel position of the bicycle, so that the two clamping claws of the second clamping mechanism clamp the inner side of the front wheel steel rim of the bicycle;

[0022] S3, making the second clamping mechanism rise along the vertical pulley track, driving the front wheel of the bicycle to rise, so that the bicycle is placed vertically.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The clamping claw with arc-shaped rod structure can fit the shape of bicycle wheel hub and clamp the inner side of tire rim more firmly, which solves the problem of unstable clamping and ensures the reliability of fixing bicycle wheel. At the same time, it also ensures that the tire will not be deformed due to excessive clamping force.

[0025] 2. The front and rear wheels are stably fixed by the coordinated action of the second clamping mechanism and the first clamping mechanism, which prevents the wheels from deflecting and the bicycle from shaking during the lifting process of the bicycle, and enhances the stability and safety of the device; wherein, the rear wheel of the bicycle is clamped by the first clamping mechanism, so that the rear wheel can be fixed and will not swing during the descent of the bicycle, which overcomes the problem in the prior art that the rear wheel only limits the wheel in the direction of movement and deflects and becomes unstable during the descent;

[0026] 4. By combining the lever principle with the push rod motor drive, the output force of the push rod motor is amplified by the lever, making the clamping more firm and reliable. At the same time, the L-shaped lever design makes the movement path of the clamping jaws highly consistent with the opening and closing action, reducing the space occupied by the device during the action; and the push rod motor has a thread self-locking function, which can maintain a stable clamping force; the thread self-locking function of the push rod motor can prevent the clamping jaws from loosening naturally, thereby ensuring the stability and reliability of the clamping state;

[0027] 5. The lifting drive device is integrated, and the reduction motor is used as the power. The second clamping mechanism is driven by the synchronous belt to slide up and down, thereby realizing the automatic vertical placement of the bicycle. The electric drive method can reduce the difficulty of parking, allowing users to easily park the bicycle in the designated location, which improves the convenience of use.

[0028] 6. The current Hall sensor is integrated, which is electrically connected to the reduction motor to monitor the current changes of the motor in real time when it is working. When the synchronous belt is obstructed, such as being stuck by foreign objects or slipping due to excessive tension, the load of the motor will increase, which will cause a significant change in the current. The current Hall sensor can capture this current change and convert it into an electrical signal for transmission, realizing real-time monitoring and judgment of the movement state of the synchronous belt, and can promptly detect abnormal movement of the parking device caused by motor failure or obstruction, thereby effectively protecting the parking device from damage;

[0029] 7. When the first clamping mechanism moves to the preset position along the horizontal pulley track, the magnets on the magnetic plate and the limit block are automatically aligned and generate magnetic attraction, thereby firmly positioning the first clamping mechanism at the preset position. The magnetic attraction design realizes automatic limiting of bicycle parking, and can drive the first clamping mechanism back to the initial position by magnetic attraction, so that the positioning device can automatically return to its original position after the bicycle is removed.

DETAILED DESCRIPTION

[0039] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] The prior art device drives the horizontal sliding rack and gear to move by pushing the bicycle, thereby realizing the vertical parking of the bicycle. However, this design has many shortcomings in practical applications.

[0044] First, due to individual differences in user strength, operating habits, etc., pushing a bicycle to park vertically often requires great strength and skills, which makes some users feel inconvenient when operating. Secondly, traditional devices often use U-shaped fixing structures and round steel pipes to fix bicycle wheels. This design can easily cause the wheels to shift during the lifting process of the bicycle, which in turn causes the bicycle to shake, which not only affects the stability of parking, but may also threaten the stability of the device itself and reduce its service life.

[0045] Regarding the above technical issues, such as Figures 1 to 5 As shown, the first embodiment of the present application provides an indoor bicycle parking device, including: a horizontal pulley track 100, used to carry the front and rear tires of a bicycle; a first clamping mechanism 200, slidably arranged on the horizontal pulley track 100, used to clamp the rear wheel of the bicycle; a vertical pulley track 300, vertically connected to one end of the horizontal pulley track 100, used to limit the front wheel of the bicycle; a second clamping mechanism 400, slidably arranged on the vertical pulley track 300, used to clamp the front wheel of the bicycle; the first clamping mechanism 200 and the second clamping mechanism 400 both include two clamping jaws 1 and a clamping drive device for driving the two clamping jaws 1 to perform a clamping action, and the clamping jaw 1 is an arc rod structure, which is used to fit with the inner side of the tire rim.

[0046] When in use, the front and rear tires of the bicycle are supported by the horizontal pulley track 100 to achieve preliminary positioning; the first clamping mechanism 200 is slidably installed on the horizontal pulley track 100, and the clamping claw 1 of its arc-shaped rod structure is driven by the clamping drive device to tightly fit and clamp the inner side of the rear wheel rim of the bicycle; at the same time, the vertical pulley track 300 is vertically connected to one end of the horizontal pulley track 100 to provide a limit for the front wheel of the bicycle; the second clamping mechanism 400 is also equipped with a clamping claw 1 of an arc-shaped rod structure, which slides on the vertical pulley track 300 and clamps the inner side of the front wheel rim of the bicycle; by controlling the first clamping mechanism 200 to rise along the vertical pulley track 300, the front wheel of the bicycle is lifted smoothly, driving the second clamping mechanism 400 to slide, and realizing vertical parking of the bicycle. Figure 7 shown.

[0047] The arc-shaped rod structure of the clamping jaw 1 can fit the shape of the bicycle wheel hub and clamp the inner side of the tire rim more firmly, thereby improving the clamping stability; when clamping, the arc-shaped rod structure of the clamping jaw 1 can evenly distribute the pressure to prevent the tire from being deformed due to excessive local force.

[0048] During the lifting process of the bicycle, the first clamping mechanism 200 and the second clamping mechanism 400 work together to stably fix the front and rear wheels, thereby preventing wheel deviation and bicycle shaking, and enhancing the stability and safety of the device.

[0049] like Figure 2 and Figure 3 As shown, in some embodiments, the first clamping mechanism 200 and the second clamping mechanism 400 both include a sliding assembly and a clamping assembly, the sliding assembly is used to be slidably connected to the corresponding pulley track; the clamping assembly includes a mounting plate 2, a cushion block 3, a first clamp and a second clamp; the mounting plate 2 is fixedly connected to one side of the sliding assembly, the cushion block 3 is fixedly connected to the mounting plate 2, and the first clamp and the second clamp are symmetrically fixedly connected to the cushion block 3; the first clamp and the second clamp both include a support seat 4, a lever 5 and a push rod motor 6, the support seat 4 is fixedly connected to the cushion block 3, the lever 5 is rotatably connected to the support seat 4 at the fulcrum, one end of the lever 5 is connected to the clamping jaw 1, and the other end is connected to the push rod motor 6, the other end of the push rod motor 6 is rotatably connected to the fixed plate 6a, and is connected to the mounting plate 2 through the fixed plate 6a.

[0050] The two sets of clamps are arranged in a bilaterally symmetrical manner to ensure the stability and reliability of clamping. In each set of clamps, the support seat 4 is firmly mounted on the cushion block 3, becoming the rotation fulcrum of the lever 5. One end of the lever 5 is connected to the clamping claw 1 of the arc rod structure, directly acting on the inner side of the tire rim; the other end is connected to the push rod motor 6, and the other end of the push rod motor 6 is rotatably connected to the mounting plate 2 to form a driving force transmission path. When the push rod motor 6 is working, the clamping claw 1 realizes the opening and closing action through the transmission of the lever 5, completing the clamping or release of the tire.

[0051] By combining the lever principle with the push rod motor 6, the lever 5 amplifies the output force of the push rod motor 6, making the clamping more firm and reliable. The clamping jaw 1 of the arc rod structure can fit the inner side of the tire rim, ensuring that the clamping force is evenly distributed and avoiding damage to the wheel hub.

[0052] The push rod motor 6 has a thread self-locking function, which can maintain a stable clamping force.

[0053] like Figure 2 and Figure 3 As shown, in some embodiments, the sliding assembly includes a first side plate 7 and a second side plate 8, which are respectively arranged on the two side end surfaces of the corresponding pulley track, and a plurality of locking bolts 9 are connected between the first side plate 7 and the second side plate 8; each locking bolt 9 is rotatably connected to a guide wheel 10, and the plurality of guide wheels 10 are divided into two groups, which are respectively rollingly arranged in the guide grooves on the two side edges of the corresponding pulley track.

[0054] The first side plate 7 and the second side plate 8 are tightly connected by a plurality of locking bolts 9 to achieve rigid support for the entire sliding assembly. The guide wheels 10 are divided into two groups and are respectively embedded in the guide grooves on both sides of the corresponding pulley track. When the sliding assembly moves along the pulley track, the guide wheels 10 roll in the guide grooves, reducing the friction resistance during movement and ensuring the stability of the sliding process.

[0055] In some embodiments, the lever 5 is an L-shaped rod, the corner of the L-shaped rod is rotatably connected to the support seat 4 through a pin, and the end of the L-shaped rod away from the cushion block 3 is connected to the clamping jaw 1.

[0056] The design of the L-shaped lever makes the movement path of the clamping jaw 1 highly consistent with the opening and closing action. When the push rod motor 6 is started, the lever 5 rotates around the pin shaft, driving the clamping jaw 1 to open and close along a predetermined trajectory, ensuring the stable transmission of the clamping force and reducing the space occupied by the device during the action. The clamping jaw can be designed as a bicycle brake pad, made of existing materials, and reducing costs while ensuring high reliability.

[0057] like Figure 2 and Figure 3 As shown, in some embodiments, the end surface of the cushion block 3 is provided with a U-shaped groove 11, and the U-shaped groove 11 is provided between the first clamp and the second clamp.

[0058] The design of the U-shaped groove 11 takes into account the shape and size of the tire. When the bicycle tire is pushed between the two sets of clamps, the U-shaped groove 11 first contacts the tire, providing it with an accurate pre-positioning space, ensuring that the tire can be stably placed in the predetermined position before formal clamping, providing a basis for subsequent clamping actions. Subsequently, driven by the push rod motor 6, the clamping jaws 1 of the first clamp and the second clamp perform precise opening and closing actions along the two sides of the U-shaped groove 11 to firmly clamp the tire.

[0059] like Figure 4 and Figure 5 As shown, in some embodiments, the vertical pulley track 300 is connected to a lifting drive device for driving the second clamping mechanism 400 to slide up and down; the lower end of the vertical pulley track 300 is fixedly connected to the horizontal pulley track 100 through the angle seat 12; the lifting drive device includes two synchronous belt drive mechanisms symmetrically arranged on the left and right, and the synchronous belt drive mechanism includes a mounting seat 13, a reduction motor 14, a synchronous belt 15, a driving wheel 16 and a driven wheel 17, the mounting seat 13 is fixedly arranged on the upper end of the vertical pulley track 300, the driving wheel 16 is rotatably connected to the mounting seat 13, the output shaft of the reduction motor 14 is connected to the driving wheel 16, the driven wheel 17 is rotatably connected to the rotating shaft, the rotating shaft is connected to the angle seat 12, and the synchronous belt 15 is wound around the driving wheel 16 and the driven wheel 17; a side branch of the synchronous belt 15 is connected to the second clamping mechanism 400.

[0060] The vertical pulley track 300 in this embodiment realizes the up and down sliding of the second clamping mechanism 400 through the lifting drive device. One side branch of the synchronous belt 15 is connected to the first clamping mechanism 200, so that during the lifting process, the first clamping mechanism 200 can move up and down with the synchronous belt 15, thereby realizing the automatic vertical placement of the bicycle; the use of electric drive can reduce the difficulty of parking, allowing users to easily park the bicycle at a designated location, thereby improving the convenience of use.

[0061] like Figure 6 As shown, the second clamping mechanism 400 and the synchronous belt 15 are fixed in such a manner that a clamping plate 24 is fixed on the inner side of the second side plate 8 by bolts, and the synchronous belt 15 is clamped and fixed therebetween.

[0062] like Figure 4 and Figure 5 As shown, in some embodiments, the synchronous belt drive mechanism includes a tensioning assembly, the tensioning assembly includes two idler wheels 18 and a tensioning wheel 19, the idler wheel 18 is rotatably connected to the mounting seat 13, the tensioning wheel 19 is rotatably connected to the sliding block 20, and the sliding block 20 is slidably connected to the sliding groove of the mounting seat; the mounting seat 13 is provided with a threaded hole connected to the sliding groove, and a disc-shaped threaded push rod 21 is connected through the threaded hole, one end of the disc-shaped threaded push rod 21 abuts against the sliding block 20, and the other end is suspended and connected to a knob; the synchronous belt 15 passes around the two idler wheels 18 and the tensioning wheel 19 in turn, and the idler wheel 18 is used to adjust the direction of the synchronous belt 15 so that the two branches of the synchronous belt 15 are respectively located on the two side end surfaces of the vertical pulley track 300.

[0063] The tensioning wheel 19 is rotatably connected to the sliding block 20, and the sliding block 20 can slide freely along the slide groove of the mounting seat 13. By rotating the knob on the disc-shaped threaded push rod 21, the sliding block 20 can be pushed to move in the slide groove, and then the position of the tensioning wheel 19 can be adjusted to achieve precise adjustment of the tensioning force of the synchronous belt 15, ensuring that the synchronous belt 15 always maintains an appropriate tension during the transmission process, avoiding the reduction of transmission efficiency due to relaxation.

[0064] In some embodiments, a current Hall sensor is provided in the mounting base 13, and the current Hall sensor is electrically connected to the reduction motor 14, and is used to detect current changes. The current changes are used to determine whether the movement of the device is obstructed, thereby playing a role in safety protection.

[0065] In this embodiment, a current Hall sensor is integrated inside the mounting base 13. The sensor is electrically connected to the reduction motor 14, and monitors the current change when the motor is working in real time. It can promptly detect abnormal movement of the parking device caused by motor failure or obstruction, thereby effectively protecting the parking device from damage. Specifically, when the synchronous belt 15 is smoothly transmitted between the driving wheel 16 and the driven wheel 17, the current of the reduction motor 14 will remain within a stable range. When the synchronous belt 15 is obstructed, such as being stuck by foreign objects or slipping due to excessive tension, the load of the motor will increase, thereby causing a significant change in the current. The current Hall sensor can capture this current change and convert it into an electrical signal for transmission, thereby realizing real-time monitoring and judgment of the movement state of the synchronous belt. This design improves the stability and reliability of the device.

[0066] Optionally, a limit switch is set at a predetermined position of the vertical pulley track 300. When the second clamping mechanism 400 reaches the top position, the limit switch is triggered, and the controller sends a signal to stop the reduction motor, thereby achieving automatic stopping of the bicycle after it is raised to a predetermined height.

[0067] like Figure 2 As shown, in some embodiments, a limit block 22 is fixedly provided on the side of the horizontal pulley track 100, a magnet is connected to one side of the limit block 22, and the first clamping mechanism 200 is connected to a magnetic plate 23, which cooperates with the magnet in magnetic attraction.

[0068] When the first clamping mechanism 200 moves to a preset position along the horizontal pulley track 100, the magnetic plate 23 automatically aligns with the magnet on the limit block 22 and generates a magnetic force, thereby firmly positioning the first clamping mechanism 200 at the preset position. The magnetic attraction design realizes the automatic limit of bicycle parking, and the first clamping mechanism 200 can be driven back to the initial position by the magnetic attraction method, so that the positioning device can automatically return to its original position after the bicycle is removed.

[0069] By designing a magnetic plate 23 and a limit block 22 in the first clamping mechanism 200 for magnetic attraction, the first clamping mechanism 200 can automatically return to a fixed position after each bicycle is taken out, so that each time the bicycle is placed, the first clamping mechanism 200 is located at a predetermined position, avoiding errors that may be caused by manual position adjustment.

[0070] A second aspect of the present application provides an indoor bicycle parking method, comprising:

[0071] S1, placing the front and rear wheels of the bicycle on the horizontal pulley track 100;

[0072] S2, sliding the first clamping mechanism 200 to the rear wheel position of the bicycle, so that the two clamping claws 1 of the first clamping mechanism 200 clamp the inner side of the rear wheel rim of the bicycle;

[0073] The second clamping mechanism 400 is slidably displaced to the front wheel position of the bicycle, so that the two clamping claws 1 of the second clamping mechanism 400 clamp the inner side of the front wheel steel rim of the bicycle;

[0074] S3, the second clamping mechanism 400 is raised along the vertical pulley track 300, driving the front wheel of the bicycle to rise, so that the bicycle is placed vertically.

[0075] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
