Description

Technical Field

[0001] The utility model relates to a bicycle parking device, in particular to a bicycle clamping and positioning device. Background Art

[0002] At present, with the change of peak hours in urban subway stations, bus stations, community entrances and other places, there is a problem of nowhere to store bicycles, random stacking and difficulty in retrieving bicycles. In order to solve this problem, three-dimensional bicycle parking garages are built near these places to store bicycles, reducing the problem of large area occupied by bicycles and inconvenient storage and retrieval.

[0003] The existing three-dimensional bicycle parking garage is described in the Chinese patent with the authorization announcement number CN208168482U, which discloses a three-dimensional bicycle parking garage, including a round tower-shaped garage, an electric door and multiple parking spaces located on the side wall of the round tower-shaped garage, a lifting and rotating device located at the center of the round tower-shaped garage, a clamp connected to the lifting and rotating device through a linear guide rail, and a controller electrically connected to the lifting and rotating device and the clamp respectively. This system controls the clamp to clamp the bicycle through the controller, and controls the lifting and rotating device to drive the clamp to lift and rotate synchronously, so that the bicycle can be intelligently stored and retrieved at multiple parking spaces on the round tower-shaped garage. The bicycle can be transported, lifted, and rotated synchronously, achieving the technical effect of storing and retrieving bicycles at parking spaces at different angles and heights in the round tower-shaped garage.

[0004] Although this solution improves the efficiency of bicycle storage and retrieval, it requires multiple control coordination of sensors and automatic doors, the movements are cumbersome, and the control system is demanding. It also requires major changes to existing parking garages, which is not conducive to vigorous promotion. In existing parking garages, bicycles are first parked in the garage, and then the bicycles are lifted to the designated position using a clamping structure. When the bicycles are parked in the garage, they are not fixed. Bicycles are parked using kickstands, which are easily accidentally touched by the clamping structure. There is also the problem of unstable placement when they are placed later. Utility Model Content

[0005] Purpose of the utility model: The purpose of the utility model is to provide a clamping and positioning device that can fix and automatically lock a bicycle.

[0006] Technical solution: The utility model provides a bicycle clamping and positioning device, including a guide groove for placing a bicycle, a clamp arm for clamping the bicycle is provided in the guide groove, and a synchronously rotating gas spring is connected to the clamp arm; a pressure plate is provided between the clamp arms; and the gas spring is symmetrically arranged below the pressure plate.

[0007] Furthermore, the guide groove is provided with a positioning groove and a placement groove for placing the wheel.

[0008] Furthermore, the clamp arms are symmetrically installed on both sides of the positioning slot, and the gas springs are also symmetrically installed on both sides of the positioning slot.

[0009] Furthermore, the end of the clamp arm is fixedly connected to a rotating shaft, the positioning groove is rotatably connected to the rotating shaft, and the end of the gas spring is fixedly connected to the rotating shaft.

[0010] Furthermore, the pressing plate is located in the middle of the positioning groove, and the clamp arms are symmetrically installed on both sides of the pressing plate.

[0011] Furthermore, fixing pieces connected to the positioning grooves are provided at both ends of the rotating shaft.

[0012] Furthermore, the gas spring is hinged to the pressure plate.

[0013] Beneficial effects: Compared with the prior art, the utility model has the following advantages: the utility model places the bicycle wheel through the positioning groove and the placement groove, and then during the placement process, the pressure plate in the positioning groove moves downward due to the gravity of the bicycle, causing the gas spring to rotate downward, thereby driving the clamp arm to lock the wheel, ensuring that the bicycle is upright and fixed, and there is no need to unlock it when transferring and picking up the bicycle. The body is lifted, the gravity is reduced, and the clamp arm is opened to complete the unlocking. During the process of picking up and placing the bicycle, the body remains stable and there is no problem of the body tipping over. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0019] like Figure 1-3As shown, a guide groove 2 for placing bicycles is arranged in front of the automatic door 1 at the entrance and exit of the bicycle stereo parking garage, and a clamping and positioning device for bicycle tires is arranged on the guide groove 2. The clamping and positioning device includes a positioning groove 4 and a placement groove 3 for placing the front and rear wheels. The placement groove 3 is close to the automatic door 1, and a pressure plate 5, a clamp arm 6, a gas spring 7 and a rotating shaft 8 are installed in the positioning groove 4; one end of the gas spring 7 is hinged to the pressure plate 5, and the other end is fixedly connected to the rotating shaft 8; the rotating shaft 8 is fixedly connected to the end of the clamp arm 6; the pressure plate 5 is located in the middle of the positioning groove 4, and the clamp arms 6 are symmetrically distributed on both sides of the pressure plate 5. The rotating shaft 8 is connected to the guide groove 2 through a fixing member 9, and the gas spring 7 is symmetrically installed below the pressure plate 5 and between the clamp arms 6 on both sides.

[0020] like Figure 2 As shown, in the initial state, the pressing plate 5 is at the upper limit position, and the clamp arms 6 on both sides are in the open state. The front wheel or the rear wheel of the bicycle is placed in the placement groove 3, and the other wheel is placed in the positioning groove 4, as shown in FIG. Figure 4 As shown, at this time, the pressure plate 5 is pressed down by the weight of the bicycle, and the gas spring 7 starts to rotate from the hinge point A with the pressure plate 5 and compresses and shortens the pull rod of the gas spring 7. The pull rod of the gas spring 7 shortens and drives the rotating shaft 8 to rotate, thereby driving the clamp arms 6 on both sides to rotate toward each other until the clamp arms 6 engage with the bicycle wheel, as shown in FIG. Figure 5 As shown, the bicycle is clamped and fixed.

[0021] After the storage operation is completed, the clamping structure of the bicycle stereo garage extends out of the automatic door 1, lifts up the wheel clamp in the placement slot 3, and the wheel in the positioning slot 4 is subjected to an upward force, the pressure on the pressure plate 5 is reduced, and the gas spring 7 is reset to push the pressure plate 5 upward, and the pressure plate 5 moves up. The gas spring 7 rotates at the hinge A below the pressure plate 5 and resets and extends the gas spring 7 pull rod. The gas spring 7 pull rod is reset and extended and the rotating shaft 8 is rotated at the same time, and the clamp arms 6 on both sides are opened, and the wheel is disengaged from the clamping positioning device in the positioning slot 4. The clamping mechanism pulls the bicycle into the stereo garage to complete the parking operation.
