Technical Field

[0001] The utility model relates to the technical field of bicycle parking, in particular to a connecting rod translational lifting mechanism and a bicycle parking device. Background Technique

[0002] Under the background of adhering to sustainable development, energy conservation and environmental protection have become the theme of the whole people, and its international development will also be the general trend. Under such a premise, bicycles, as a green and low-carbon travel mode, have become more and more popular. Especially with the economic development, shared bicycles have become an indispensable means of transportation. The fast and flexible characteristics of bicycles bring great convenience to people going to school and work. However, while bringing convenience to people, a series of problems have also emerged. The most prominent one is the problem of bicycle parking. Since bicycles do not have high parking conditions like ordinary cars, people usually park bicycles rather casually, without fixed parking points, and do not consider the convenience of subsequent vehicle retrieval when parking, resulting in the vehicles occupying a lot of unnecessary space when parked. Especially when people use shared bicycles, the parking is even more chaotic and disorderly and there is a situation of occupying the sidewalk. When there are too many bicycles parked, the handlebars of adjacent two bicycles will also hinder each other, prone to bumping, tipping over and often showing a domino chain effect, extremely easy to cause damage to bicycles. Content of the Utility Model

[0003] In view of this, the purpose of the utility model is to solve the problems existing in bicycle parking and access in the background technique, and provide a vertical bicycle parking device that can save parking floor area and improve vehicle access efficiency.

[0004] To solve the above technical problems, the utility model provides a connecting rod translational lifting mechanism, including an upper slider and a lower slider slidably sleeved on a vertical rod, and a fixed seat and a middle connecting rod between the sliders. The middle connecting rod is eccentrically pivoted on the fixed seat, one end thereof is rotatably connected to an upper connecting rod, and the other end is rotatably connected to a lower connecting rod. The end of the upper connecting rod far from the middle connecting rod is pivotally connected to the upper slider, and the end of the lower connecting rod far from the middle connecting rod is pivotally connected to the lower slider;

[0035] Embodiment 1

[0036] Reference Figures 1-7, the present utility model provides a connecting rod translational lifting mechanism, which can achieve the overall horizontal lifting effect by controlling the relative movement of the slider sleeved on the vertical rod. Its structural composition includes an upper slider 1 and a lower slider 5 sleeved on the vertical rod 9, and a fixed seat 8 and a middle connecting rod 3 between the sliders. The middle connecting rod 3 is eccentrically pivoted on the fixed seat 8, one end of which is rotatably connected to the upper connecting rod 2, and the other end is rotatably connected to the lower connecting rod 4. The end of the upper connecting rod 2 far from the middle connecting rod 3 is pivoted on the upper slider 1, and the end of the lower connecting rod 4 far from the middle connecting rod 3 is pivoted on the lower slider 5 to jointly form the linkage effect between the rods. In addition, the connecting rod translational lifting mechanism described in this embodiment further includes a translational connecting rod 6 whose end is rotatably connected to the fixed seat 8 and is horizontally arranged at intervals with the middle connecting rod 3. One end of the translational connecting rod 6 far from the fixed seat 8 is connected to the middle connecting rod 3 through a translational member 7. Since the two ends of the middle connecting rod 3 and the translational connecting rod 6 are respectively hinged on the translational member 7 and the fixed seat 8 and are arranged in parallel with each other, when the slider moves relative to the fixed seat 8 along the vertical rod 9, it can be seen vertically that the slider drives the middle connecting rod 3 to start rotating around the pivot point on the fixed seat 8 through the upper connecting rod and the lower connecting rod, and horizontally, it can be seen that the parallelogram structure formed by the pairwise hinged connection of the middle connecting rod 3, the fixed seat 8, the translational connecting rod 6 and the translational member 7 starts to deform under the drive of the middle connecting rod 3. Specifically, when the slider slides away from the fixed seat 8, it can cause the middle connecting rod 3 to rotate clockwise around the pivot point on the fixed seat 8, and the parallel translational connecting rod 6 also rotates clockwise around the pivot point on the fixed seat 8 synchronously, and jointly drives the translational member 7 pivoted at the end position to be lifted horizontally from bottom to top; similarly, when the slider slides towards the fixed seat 8, it can cause the middle connecting rod 3 to rotate counterclockwise around the pivot point on the fixed seat 8, and at the same time the translational connecting rod 6 also rotates counterclockwise around the pivot point on the fixed seat 8, and jointly drives the translational member 7 pivoted at the end position to fall horizontally from top to bottom.

[0037] One of the sliders is the active part, and a driving device is connected inside the active part. The driving device is a cylinder or a motor. And the relatively one slider is the passive part, and a damper is arranged inside the passive part. When the slider slides towards the fixed seat 8, the damper provides a buffering force against the sliding direction of the slider. In addition, in this embodiment, on the path of the sliding stroke of the active part, using the lever principle, by eccentrically pivoting the middle connecting rod 3 on the fixed seat 8, when the lower slider 5 is designed as the active part, the eccentric pivot point of the middle connecting rod 3 is arranged on the side close to the lower connecting rod 4, so as to ensure that when the lower slider 5 slides a short distance, it can drive the translational member 7 to generate a large lifting amplitude.

[0038] Embodiment Two

[0039] Reference Figures 8-12The utility model provides a bicycle parking device, which is equipped with the connecting rod translation lifting mechanism described in the previous embodiment as a functional component for smoothly lifting a bicycle to park it vertically. Specifically, the bicycle parking device also includes a caliper 701 horizontally arranged along the length direction of the translation member 7, and the caliper 701 is U-shaped, one open end of which is rotatably connected to a cross bolt 702 through a torsion spring, and the other end is provided with a groove 7011 in which the cross bolt 702 is embedded. When the connecting rod translation lifting mechanism is in the lower limit position, the position is the bicycle mounting position. Push the front wheel or rear wheel of the bicycle toward the U-shaped interior of the caliper 701, and push the cross bolt 702 on the caliper 701 to rotate accordingly. When the wheel body is pushed to the inner edge of the caliper 701, the cross bolt 702 disengages from the wheel rim and returns to the initial position under the action of the torsion spring. Then, driven by the active member in the connecting rod translation lifting mechanism, the translation member 7 is lifted horizontally upward from bottom to top. At this time, the bicycle is loaded onto the cross bolt 702 with the bicycle's own weight, and the direction is straight downward. Since the bicycle's gravity is directly loaded onto the cross bolt 702 vertically, the free end of the cross bolt 702 is pressed into the groove 7011 of the other arm of the caliper 701 to ensure that the wheel will not be loosened from the caliper 701 during the lifting process. In addition, when the user needs to take the bicycle and lower the caliper 701, the connecting rod translation lifting mechanism returns to the lower limit position. At this time, the bicycle's own weight is no longer applied to the cross bolt 702, but the bicycle's own weight is borne by the ground. At this time, as long as the bicycle is pulled backward, the bicycle wheel can rotate in the horizontal plane with the cross bolt 702 until the bicycle wheel body escapes from the limit of the caliper 701, and the cross bolt 702 also returns to the initial position when the torsion spring is used.

[0040] In addition, it also includes a base 10 for fixing the upright pole 9, Figure 10 As shown, the base 10 includes a base embedded in the ground and installed, and a flange sleeve 103 fixedly connected to the base. The flange sleeve 103 has four first through holes equidistantly surrounding the circumference. The first through holes cooperate with the self-rebounding limit clamping assembly at the end of the upright 9 to fix the upright 9. From the appearance of the base, it includes two reverse orthogonal overlapped channel steels, and the wing ends of the channel steels are arranged upward to form a guide groove, and the extension direction of the guide groove is consistent with the opening direction of the caliper. In other words, the cross-shaped channel steel base includes a lower channel steel 101 that is parallel to the road surface elevation and has an opening facing downward, and an upper channel steel 102 that is perpendicular to the road surface and has an opening facing upward. The upward opening of the upper channel steel 102 is equivalent to a guide rail, which guides the bicycle and allows the bicycle to be pushed in along the channel steel opening. In addition, the channel steel in this direction also plays a supporting and anti-lodging role.

[0041] The flange sleeve 103 is fixedly connected to the upper channel steel by welding, and four first through holes are equidistantly arranged around the flange sleeve 103. The first through holes cooperate with the self-rebounding limit clamping assembly at the end of the vertical pole 9 to fix the vertical pole 9. Figure 9As shown in the figure, the resilient limit clamping component includes a top bead 901 penetrating through the second through-hole at the end of the vertical rod 9, and a compression spring 902 that supports the top bead 901. The apertures of the first through-hole and the second through-hole are the same and their arrangement positions are adapted to each other. The radius of the top bead 901 is not less than the radii of the first through-hole and the second through-hole. When the end of the vertical rod 9 penetrates into the flange sleeve 103 along the opening direction of the flange sleeve 103, the top bead 901 extending out of the second through-hole at its end retracts due to the squeezing force of the flange inner wall, reacting on the compression spring 902 and causing it to retract into the vertical rod 9. As the penetration degree of the vertical rod increases, the top bead 901 reaches the first through-hole of the flange sleeve 103, and the compression spring 902 pushes the top bead 901 out again, thus realizing the positioning of the vertical rod.

[0042] Arrange the assembled parking devices in Figure 11 as shown in Figure 12 the figure. When multiple parking devices are connected in series, an integrated ceiling can be used for connection to enhance the anti-tipping ability, or it can replace the roadside fence, combining parking and the fence into one, further saving the comprehensive setting cost of municipal facilities and having good social benefits. In this embodiment, the bicycles are vertically parked through the connecting rod translational lifting mechanism, which not only reduces the occupied road width, but also, since the seat surface is in the vertical direction, sunlight will not directly shine on it and rainwater is not easily collected, which is beneficial to extending the effective life cycle length of the bicycles. In addition, in this embodiment, by setting a damper in the passive component, it can be ensured that the bicycle slowly descends under the action of gravity when being retrieved, thus greatly improving the safety of the retrieval operation and avoiding injuries to personnel or damage to the bicycle caused by the rapid descent of the bicycle. When mounting the bicycle, the guide groove is used for cooperation, which is convenient for parking and retrieval without changing the current user's cycling habit, providing a better user experience and being easier to promote.

[0043] As described above, it is only the preferred specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, making non-substantive modifications to the present utility model using this concept, shall fall within the scope of infringement of the protection of the present utility model.
