[0002] Bicycles are a low-carbon, environmentally friendly, and green mode of transportation, and they also help improve the physical fitness of cyclists. Bicycles are used by a wide range of people for various purposes, such as commuting, going to school, leisure, and fitness.

[0003] The most common way to park bicycles is with bicycle racks installed on roadsides and sidewalks. The bicycle is positioned flat on the rack with both wheels touching the ground. This method takes up a lot of space and wastes a lot of usable space. This drawback is not only reflected on public roads, but also in homes and residential areas.

[0004] Based on this, existing designs disclose bicycle parking devices that can be placed upright, such as patent document CN111086576B, which has a front wheel suspension device for positioning the front wheel of the bicycle and a rear wheel support device for cooperating with the rear wheel of the bicycle, so that the bicycle can be placed upright. However, in this method, the bicycle needs to be manually lifted up so that the front wheel is hooked on the hook of the front wheel suspension device, which is inconvenient to operate. Therefore, the applicant has made further improvements. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a frame that facilitates vertical parking of bicycles. The bicycle only needs to be pushed until the front wheel is above the support. Then, by pressing down on the front wheel or by using the weight of the front wheel itself, the wheel positioning unit is automatically unlocked. After unlocking, the weight of the drive unit lifts the front wheel until the bicycle is in an upright position.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0044] See Figures 1-15 A frame for facilitating vertical parking of bicycles includes a stand 1, a drive unit 2, and a wheel positioning unit 3. The stand 1 can be designed to be upright, including side plates 11, back plates 12, top plates 13, and bottom plates 14 arranged at intervals on the left and right sides, to form a stand that can be placed upright on the ground or leaned against a wall. The front of the stand is open. Of course, to make the stand more secure, it can be fixed to the ground or wall by fasteners or other means.

[0045] In this embodiment, a pulley 15 is installed on the top of the support frame 1. For example, a pulley support frame can be installed on the inner wall of the top plate 13 of the support frame 1, and the pulley 15 is installed on the pulley support frame. A rope 16 is wound on the pulley 15. The rope 16 can be a high-strength rope-like object such as a steel wire rope.

[0046] In this embodiment, a drive unit 2 is slidably arranged inside the frame 1. The upper end of the drive unit 2 is connected to one end of the rope 16. The drive unit 2 is a weight block, and its weight is sufficient to change the bicycle from a flat position to an upright position. Its specific weight can be adaptively adjusted and replaced according to the weight range of the bicycle. For example, it can be designed in multiple models and replaced according to actual needs.

[0047] Furthermore, the side plates 11 arranged on the left and right sides of the support frame 1 can be respectively provided with corresponding first tracks 111. The first track 111 can be formed by the side plate surface defined by the distance between two spaced ribs. Correspondingly, the drive unit 2 is provided with a number of first pulleys 21 that cooperate with the first track 111. For example, a first pulley 21 can be provided at each of the four corners of the drive unit 2 so that the drive unit 2 and the support frame 1 can form a sliding cooperation relationship, and limit the drive unit 2 to go straight up and down along the first track 111, thereby improving the stability of the device during use.

[0048] The wheel positioning unit 3 includes a base 31, a first connector 32, a tension spring 33, and a support 34. The base 31 includes a base plate 311 and a connecting cover 312 mounted on the base plate 311. The base plate 311 is provided with a plurality of second pulleys 3111. Correspondingly, the left and right side plates of the support frame 1 are respectively provided with sliding grooves 17 adapted to the second pulleys 3111, which serve as the track for their lifting and lowering actions. The sliding grooves 17 can also be formed by the side plate surface defined by the distance between two spaced ribs.

[0049] In this embodiment, the other end of the rope 16 is connected to the upper end of the base plate 311 so that it can be driven by the drive unit 2 to go straight up and down along the preset track, thereby lifting the bicycle front wheel placed on the wheel positioning unit 3 until the bicycle is placed upright.

[0050] In this embodiment, a support member 34 for supporting the wheel is installed on the substrate 311. The support member 34 can be designed as shown in the figure, formed by bending a tubular component. One end of the left rod is installed on the bent edge 3112 of the substrate 311, and then bends downward and extends outward to the outside of the substrate 311, and then extends downward. The right rod is the same. Finally, the outer ends of the left rod and the right rod are connected to form a support member 34 with a space in the middle for the bicycle wheel to sink and support the bicycle wheel. Of course, the left rod and the right rod can be designed as an integral molding or welded molding.

[0051] In this embodiment, the substrate 311 has an opening 3113 at the bottom and mounting flanges 3114 formed by bending on the left and right sides of the opening 3113. A first shaft 3115 is mounted on the two mounting flanges 3114. A first connector 32 is rotatably connected to the first shaft 3115. The opening 3113 is configured to provide sufficient space for the first connector 32 to move.

[0052] The upper end of the first connector 32 is connected to one end of the tension spring 33, and the other end of the tension spring 33 is connected to the base plate 311 so that when no external force is applied, the tension spring 33 will cause the first connector 32 to return to its original state.

[0053] In this embodiment, the lower end of the first connector 32 includes a hook portion 321. As one implementation, the first connector 32 can be a metal component, which is formed by bending the left and right ends of a metal plate to form the mating portion 322 of the first connector, and the hook portion 321 is formed at the lower end of the mating portion 322. The upper end of the mating portion 322 is provided with a hole that mates with the first shaft 3115 and a hole that mates with the tension spring 33.

[0054] The first connector 32 is used to cooperate with the second connector 4 installed at the bottom of the stand 1 to lock the wheel positioning unit 3. In the locked state, the wheel positioning unit 3 is located at the bottom of the stand 1, and the drive unit 2 is pulled to the top of the stand 1. At this time, the front wheel of the bicycle is pushed into the support member 34 in a way that can push the bicycle forward, making the operation more convenient.

[0055] Specifically, the bottom of the support frame 1 includes a support plate 18, which can be formed by bending the base plate 14 of the support frame 1. The support plate 18 has a through hole 181, and connecting pieces 182 are formed at the left and right ends of the through hole 181 respectively. A second shaft 183 is installed on the two connecting pieces 182. The second connecting piece 4 is rotatably set on the second shaft 183 and passes through the through hole 181, that is, the through hole 181 can provide sufficient space for the second connecting piece 4 to move.

[0056] In this embodiment, the second connector 4 can also be a metal component, formed by bending the left and right ends of a metal plate to form connecting flanges 41. The two connecting flanges 41 are provided with holes that are compatible with the second shaft 183. At the same time, the upper end of the metal plate is bent to form a number of flanges 42. The position and number of flanges 42 correspond one-to-one with the position and number of hooks 321 on the first connector 32.

[0057] like Figure 12 As shown, the wheel positioning unit 3 is in the locked state, locked in the parking position. At this time, the folded edge 42 abuts against the upper edge of the hook 321, and fastens the first connecting piece 32, thereby limiting the entire wheel positioning unit 3 and preventing it from being pulled up by the drive unit 2.

[0058] In one embodiment, a torsion spring is provided between the second shaft 183 and the second connecting member 4, so that when no external force is applied, the end of the folded edge of the second connecting member 4 abuts against the side wall of the upright plate 18 above the through hole 181. Figure 6 As shown.

[0059] For unlocking wheel alignment unit 3, such as Figure 13As shown, when the wheel positioning unit 3 is pressed down, the hook 321 of the first connector 32 moves down along the side wall of the second connector 4. Since its upper end is rotatable, the first connector 32 swings along the side wall of the second connector 4 to avoid it, until the hook 321 of the first connector 32 leaves the side wall of the second connector 4 and is positioned below the second connector 4, hooking the bottom of the second connector 4. At this point, the force pressing down on the wheel is released (e.g., by the user manually pressing down on the bicycle wheel, and then releasing the user's hand or ceasing to press down on the bicycle wheel). (If the wheel positioning unit is pressed down by the weight of the bicycle itself, it can be done by the user slightly lifting the front of the bicycle). (Balancing force), influenced by the weight of the drive unit 2, it drives the wheel positioning unit 4 upward. During this process, the first connecting member 32 moves upward and its hook 321 drives the second connecting member 4 to rotate until the second connecting member 4 rotates to the limit position (limited by the upper edge of the through hole 181 on the upright plate 18). At this time, the side of the second connecting member 4, which is arranged in an inclined shape, cooperates with the hook 321 of the first connecting member 32 and cannot lock the first connecting member 32. Therefore, as the first connecting member 32 continues to move upward, it can swing and disengage from the second connecting member 4 (because the upper end of the first connecting member 32 can rotate), eventually driving the front wheel of the bicycle to move upward until the bicycle is upright. Figure 15 As shown.

[0060] When the wheel positioning unit 3 drives the bicycle front wheel upward, it is also necessary to position the bicycle front wheel. In this embodiment, a bent tube 5 for passing through the vehicle wheel hub is provided at the upper end of the base 31. The inner end of the bent tube 5 is fixed to the base plate 311 of the base 31, and the other end extends outward from the base 31 and can extend into multiple bent segments. Its outermost end 51 bends to the left and right again. That is, when the bent tube 5 is set at the left end of the base 31, its outermost end bends to the right; when the bent tube 5 is set at the right end of the base 31, its outermost end bends to the left. The bending length must ensure that it can be inserted into the bicycle front wheel hub, such as passing through the gap between two adjacent ribs on the bicycle front wheel hub.

[0061] In this embodiment, a plurality of stop posts 19 are provided on the upright frame 1. As one implementation method, a plurality of stop posts 19 are provided on the left and right sides of the opening surface of the upright frame 1, with two stop posts distributed on the left and right as a group, and multiple groups are provided from bottom to top.

[0062] Corresponding to the stop post 19, in this embodiment, a third shaft 61 is installed on the upper end of the connecting cover 312 of the base 31, and a pressure tongue 62 is rotatably connected to the third shaft 61. Specifically, the left and right extension walls 621 of the pressure tongue 62 are rotatably set on the third shaft 61, and the left and right extension walls 621 can be formed by bending the pressure tongue body.

[0063] Meanwhile, a limiting shaft 63 is provided on the left and right extension walls 621 of the pressure tongue 62. The horizontal height of the limiting shaft 63 is higher than that of the third shaft 61. When the pressure tongue 62 is installed on the connecting cover 312, the limiting shaft 63 is located above the upper edge of the connecting cover 312. When the pressure tongue 62 rotates and retracts, the limiting shaft 63 is moved and displaced from the stop post 19. The displacement means that when the wheel positioning unit 3 moves upward, the limiting shaft 63 will not touch the stop post 19, and the stop post 19 does not have a limiting effect on it. When the pressure tongue 62 is in the unfolded state, the limiting shaft 63 is located directly below the stop post 19. That is, at this time, the stop post 19 is located on the longitudinal movement path of the limiting shaft 63 (the limiting shaft 63 moves upward synchronously with the wheel positioning unit 3). When the pressure tongue 62 retracts, the stop post 19 can limit the wheel positioning unit 3 to avoid accidental operation that could cause the drive unit 2 to fall down, and can improve operational safety.

[0064] Furthermore, the base plate 311 of the base 31 includes a limiting piece 3116. When the tongue 62 is in the unfolded state, the inner end wall 622 of the tongue 62 (specifically, the part between the left and right extension walls 621) abuts against the limiting piece 3116. A torsion spring is disposed between the tongue 62 and the third shaft 61 to keep the tongue 62 in the unfolded state when there is no external force acting on it.

[0065] To further improve the limiting effect of the bicycle front wheel when placed, in this embodiment, a sliding member 71 is slidably arranged on the stand 1. The pulley on the sliding member 71 can share a groove 17 with the second pulley 3111 on the base plate 311. A limiting member 72 for laterally limiting the wheel is provided on the sliding member 71. The limiting member 72 can be formed by bending a metal strip and extends outward from the stand 1. During the process of the bicycle front wheel being driven upward by the wheel positioning unit 3, the wheel positioning unit 3 contacts the sliding member 71 (specifically, the base plate 311 on the base 31 can contact it). The sliding member 71 is then driven upward by the wheel positioning unit 3 until the bicycle is in an upright state.

[0066] When the limiting member 72 is located at the front wheel of the bicycle, its size is sufficient to ensure that it laterally blocks at least the tire portion of the front wheel of the bicycle, and of course it can also extend beyond the tire portion, and in some cases it can further laterally block the rim portion.

[0067] In this embodiment, a set of stop posts 19 on the upright 1 are used to limit the sliding member 71, so that it is held in the middle position of the upright 1 without external force, separated from the bent tube 5 on the wheel positioning unit 3, to facilitate the entry of the bicycle front wheel. Figure 15 As shown, if the limiting member 72 is arranged together with the bent tube 5, it will make it difficult for the bicycle front wheel to enter. The bent outer end of the bent tube 5 restricts the bicycle front wheel from entering in the front-back direction, and the limiting member 72 restricts the bicycle front wheel from entering in the left-right direction.

[0068] The steps for using the bicycle parking device are as follows:

[0069] S1. Push the bicycle front wheel onto the support;

[0070] S2. Press down on the front wheel of the bicycle or use the weight of the front wheel itself to cause the wheel positioning unit to move downward, so that the first connector and the second connector are separated, and the wheel positioning unit is unlocked;

[0071] S3. The drive unit drives the wheel positioning unit and the front wheel of the bicycle to rise up until the bicycle is in an upright position through the rope.

[0072] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
