DETAILED DESCRIPTION

[0045] The following combination Figure 1-12 The utility model is described in detail.

[0046] This embodiment provides a lifting mechanism for vertical parking of a bicycle, comprising a column 10, a lifting module and a driving module. Specifically,

[0047] The bottom end of the column 10 is vertically fixed to the ground;

[0048] The end of the lifting module close to the ground is provided with a mounting module 40 for mounting a bicycle; and

[0049] The driving module is disposed at the top of the column 10 , and one end of the lifting module away from the ground is hinged to the driving module.

[0050] When in use, the driving module is activated to control the retraction or extension of the lifting module, thereby lifting the bicycle to a vertical parking state or down to a horizontal retrieval state, replacing the existing parking method placed on the ground with a vertical suspension in mid-air, reducing the occupation of the crosswalk, while also achieving the effect of neatly placing the bicycle.

[0051] The center line of the front and rear wheels of a vertically placed bicycle is tilted at an angle to the ground, so that the front of the bicycle seat is tilted downward to reduce exposure to the sun and rain. Figure 12 The width of the road occupied by the bicycle is divided on both sides of the pillar 10, that is, the handlebars and pedals are distributed on both sides of the pillar 10. Compared with a bicycle that is completely on one side of the pillar 10, the width of the road occupied is smaller, and the arrangement of the pillars 10 on the sidewalk is more flexible.

[0052] In this embodiment, the drive module includes a cantilever beam 301, a screw rod 302 and a motor 304. The cantilever beam 301 is vertically connected to the top of the column 10, and a rotating bearing 303 is provided at both ends of the cantilever beam 301. The two ends of the screw rod 302 are rotatably connected to the rotating bearing 303, and the external thread of the screw rod 302 is adapted to the slider 305. The motor 304 is fixedly connected to the cantilever beam 301, and its output shaft is connected to the screw rod 302, which drives the slider 305 to move back and forth by rotating the screw rod 302. When in use, the slider 305 can only be driven to reciprocate by rotating the screw rod 302, and the screw rod 302 cannot be driven to rotate by the slider 305, so as to avoid the situation where the bicycle falls off after being mounted, thereby protecting the bicycle and personal safety.

[0053] In this embodiment, the lifting module includes several interconnected scissor-type mechanisms, and the scissor-type mechanisms include a first link 201 and a second link 202. The middle part of the first link 201 is hinged to the middle part of the second link 202, and the two ends of the first link 201 are respectively hinged to the ends of the second link 202 in the scissor-type mechanism located at an adjacent position, and the two ends of the second link 202 are respectively hinged to the ends of the first link 201 in the scissor-type mechanism located at an adjacent position.

[0054] In this embodiment, a first linear bearing 501 is provided at the hinge of at least one first link 201 and second link 202, and the linear bearing is slidably mounted on the column 10. Furthermore, a first linear bearing 501 is provided at the hinge of each first link 201 and second link 202 on the same side, and the first linear bearing 501 is slidably mounted on the column 10 to reduce shaking of the lifting module during extension and retraction.

[0055] In this embodiment, one end of the first link 201 and the second link 202 at the top of the lifting module is fixedly connected to the column 10, and the other end is hinged to the slider 305. At the bottom of the lifting module, one end of the first link 201 and the second link 202 is provided with a second linear bearing 502. The second linear bearing 502 is slidably mounted on the column 10 and is connected to the mounting module 40. Specifically, the end of the first link 201 at the top of the lifting module is fixedly connected to the column 10, and the end of the second link 202 is connected to the slider 305. The end of the second link 202 at the bottom of the lifting module is provided with a second linear bearing 502. In actual application, the first and second linear bearings 501 and 502 can be of the same specifications.

[0056] In this embodiment, Figures 3 to 6 As shown, the mounting module 40 includes a main body 401, the main body 401 has a accommodating space with an opening facing downward, a first return spring 402 is provided on one side of the opening, a slide groove 4011 is provided on the other side of the opening, and a limiting groove 4012 is provided in the slide groove 4011; it also includes a cross bolt 403, one end of the cross bolt 403 is connected to the first return spring 402 and can rotate in a horizontal plane, and the other end of the cross bolt 403 can swing in the slide groove 4011 and can be detachably engaged in the limiting groove 4012.

[0057] In this embodiment, a connecting section 4017 is provided at the top of the body 401 for connecting to the second linear bearing 502. The body 401 is provided with a mounting plate 4013, located on one side of the opening. The mounting plate 4013 is provided with a first mounting hole 4014 and a second mounting hole 4015, arranged sequentially along the direction of gravity. The diameter of the second mounting hole 4015 is smaller than that of the first mounting hole 4014, so that a limiting surface is formed between the first and second mounting holes 4014, and the first and second mounting holes 4015 are coaxially arranged. The mounting plate 4013 is also provided with a positioning hole 4016. The body 4013 further includes a rotating shaft 404, with a radially outwardly extending protrusion 406 formed on the central surface of the rotating shaft 404. The protrusion 406 abuts against the limiting surface, ensuring that the rotating shaft 404 does not fall off the mounting plate 4013.

[0058] In this embodiment, one end of the rotating shaft 404 is provided with an end cap 405, which is surrounded by a plurality of retaining grooves 4051. A cross bolt 403 is hingedly connected to the other end of the rotating shaft 404. The first return spring 402 is a torsion spring, which is sleeved around the rotating shaft 404 and positioned between the end cap 405 and the protrusion 406. The torsion spring has a first fixed end 4021 and a second fixed end 4022 at its ends. During installation, the torsion spring is first sleeved around the rotating shaft 404, the second fixed end 4022 is inserted into the positioning hole 4016, and the first fixed end 4021 is engaged with the retaining groove 4051. The end cap 405 is then fixedly connected to one end of the rotating shaft 404. The connection between the end cap 405 and the rotating shaft 404 can be achieved by welding, bonding, or other methods. During use, the horizontal thrust applied to the cross bolt 403 drives the rotating shaft 404 to rotate. When the horizontal thrust disappears, the elastic force of the first return spring 402 drives the rotating shaft 404 to rotate to the initial position, thereby driving the cross bolt 403 to twist to the initial position.

[0059] In this embodiment, a second return spring is provided between the cross bolt 403 and the rotating shaft 404, one end of the second return spring is connected to the cross bolt 403, and the other end of the second return spring is connected to the rotating shaft 404, so that the cross bolt 403 always remains horizontal or slightly tilted upward in the horizontal direction under the elastic force of the second return spring, making it easy for the cross bolt 403 to enter and exit the slide groove 4011.

[0060] In this embodiment, the cantilever beam 301 is equipped with a first travel switch, which is controllably connected to the motor 304. When the motor 304 drives the lifting module to raise the mounting module 40 to its highest point, the slider 305 moves to the leftmost end of the screw rod 302, triggering the first travel switch and stopping the motor 304. The cantilever also has a second travel switch, which is controllably connected to the motor 304. When the motor 304 drives the lifting module to lower the mounting module 40 to its lowest point, the slider 305 moves to the rightmost end of the screw rod 302, triggering the second travel switch and stopping the motor 304.

[0061] In this embodiment, a third travel switch is installed at the bottom of the column 10, which is controlled by the motor 304. As the bicycle ascends with the lifting module, the rear wheel gradually approaches the column 10. When the rear wheel contacts the third travel switch, the motor 304 stops, and the bicycle stops ascending. At this point, the rear wheel of the bicycle abuts the ground, and the weight of the bicycle is shared by the ground and the lifting module.

[0062] The lifting mechanism for vertical parking of a bicycle proposed in this embodiment is used as follows:

[0063] When the user parks the bicycle, the bicycle is pushed forward so that the front wheel pushes the horizontal bolt 403 away and drives the rotating shaft 404 to rotate. Figure 6As shown, at this time, the first return spring 402 is compressed. When the front wheel completely enters the accommodation space, the cross bolt 403 is disengaged from the front wheel under the action of the first return spring 402 and rotates to the initial position, thereby penetrating the front wheel rim. The motor 304 is started, the screw rod 302 rotates, and the slider 305 moves to drive the lifting module to retract. When the mounting module 40 rises with the lifting module, the weight of the bicycle is loaded on the cross bolt 403. Under the action of gravity, the cross bolt 403 tilts slightly downward and embeds into the limiting groove 4012. Figure 4 As shown, the bicycle will not fall off the mounting module 40 during the lifting process. When the user takes the bicycle, the motor 304 is started to reverse and drive the slider 305 to retract, the lifting module extends, and the bicycle gradually descends until the front wheel of the bicycle touches the ground. The bicycle is pulled back so that the front wheel pushes the horizontal bolt 403 away. Figure 6 As shown, the vehicle is taken out until the cross bolt 403 is separated from the front wheel.

[0064] In this embodiment, a power generation module is also provided at the top of cantilever beam 301. This module includes a bracket 601 connected to cantilever beam 301. Bracket 601 is equipped with a solar panel 602. Solar panel 602 provides power to motor 304 while also providing shade and rain protection for the bicycle below. Solar panel 602 forms an angle α with the horizontal plane, ranging from 30 to 60 degrees, to facilitate the shedding of rainwater and dirt.

[0065] This embodiment further proposes a bicycle parking spot, comprising a lifting mechanism for vertically parking a bicycle as described above, wherein the lifting mechanisms are arranged linearly at intervals or in a circular array.

[0066] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand and implement the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
