Description

Technical Field

[0001] The utility model relates to a bicycle parking device, in particular to a bicycle wheel clamp. Background Art

[0002] The clamping devices for bicycles in existing bicycle parking garages all clamp the front wheels of bicycles, and cannot accommodate the rear wheels of bicycles with speed change sprockets and kickstands. As a result, existing bicycles must enter the garage in a prescribed order when parking, which increases the complexity of parking.

[0003] In addition, when the bicycle tire is clamped, if you want to push the bicycle to move, there is sliding friction between the bicycle tire and the contact surface of the guide groove, so the resistance is large, and the force required for pushing is also large, which consumes equipment energy, and the sliding friction also causes serious wear on the bicycle tire. Utility Model Content

[0004] Purpose of the utility model: The purpose of the utility model is to provide a bicycle wheel clamp that can reduce wear and has greater inclusiveness.

[0005] Technical solution: The utility model provides a bicycle wheel clamp, including a fixed seat and a clamping arm symmetrically arranged on the fixed seat, a driving motor for driving the clamping arm to open and close is installed on the fixed seat, a parallel connecting rod is fixedly installed on the end of the clamping arm; and a clamping plate for clamping the wheel is fixedly installed on the other end of the parallel connecting rod.

[0006] Furthermore, the splint is a bow-shaped splint.

[0007] Furthermore, a gas spring is connected between the upper connecting rod of the parallel connecting rod and the clamping plate.

[0008] Furthermore, the driving motor is installed above the fixing seat, and the clamping arm is located below the fixing seat.

[0009] Furthermore, a detection mechanism is installed on the fixed seat, and the detection mechanism is located between the clamping arms and includes a fixed vertical plate, a detection pressure plate and a sensor. The fixed vertical plate is fixedly installed on the fixed seat, the detection pressure plate is installed in front of the fixed vertical plate, the sensor is installed on the fixed vertical plate and connected to the detection pressure plate, and the sensor controls the movement of the drive motor through the controller.

[0010] Furthermore, the output shaft of the driving motor is connected to a driving gear, a transmission gear meshing with the driving gear is rotatably installed below the fixing seat, and the clamping arm is respectively connected to the driving gear and the transmission gear through a connecting shaft.

[0011] Furthermore, rubber pads are provided on the inner sides of the splints.

[0012] Working principle: When the wheel hits the detection pressure plate, the sensor receives the signal and transmits it to the controller to control the drive motor to operate; after the clamping plates of the clamping arm grab the bicycle wheel from both sides, the drive motor continues to operate to further close the clamping arm, but at this time, due to the hinged parallel connecting rod structure between the clamping plates and the clamping arm, the clamping plates no longer close in the horizontal direction, but are lifted in the vertical direction, thereby lifting the bicycle wheel off the ground.

[0013] Beneficial effects: Compared with the prior art, the utility model has the following advantages: in the process of pushing and moving the clamping plate and the parallel connecting rod, it can not only reduce the bearing capacity of the push-pull motor, but also avoid wheel wear and prevent the wheel from slipping due to excessive friction; when the clamp clamps the rear wheel of the bicycle, it can avoid protruding parts such as the foot support and the speed sprocket at the rear wheel; the structural design is scientific and reasonable, which can realize the fast, smooth and safe bicycle clamping action, the support is stable and reliable, and it has an in-place detection function to prevent empty grabbing and improve the operation efficiency of the garage.

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

[0019] like Figure 1-4As shown, a bicycle 1 is placed on a parking space, and its rear wheel is clamped by a bicycle wheel clamp, which includes a fixing seat 2 fixedly mounted on a grabbing device in a garage, a driving motor 3 installed above the fixing seat 2, an output shaft of the driving motor 3 located below the fixing seat 2, and connected to two clamping arms 4 driven by the driving motor 3; a self-lifting clamping structure is relatively arranged on the clamping arms 4, and the self-lifting clamping structure includes a parallel connecting rod 5, a gas spring 6 and a clamping plate 7 for clamping a wheel; one end of the parallel connecting rod 5 is fixedly connected to the clamping arm 4, and the other end It is fixedly connected with the clamping plate 7, which is an arched clamping plate; the gas spring 6 is installed between the upper connecting rod of the parallel connecting rod 5 and the clamping plate 7, so that the connecting rod maintains a certain anti-torsion force; the inner side of the clamping plate 7 is provided with a rubber pad 8; the fixed seat 2 is also provided with a detection mechanism, which is located between the two clamping arms 3, and includes a fixed vertical plate 9, a detection pressure plate 10 and a sensor 11; the fixed vertical plate 9 is fixedly installed on the fixed seat 2, the detection pressure plate 10 is installed in front of the fixed vertical plate 9, and the sensor 11 is installed on the fixed vertical plate 9 and connected to the detection pressure plate 10. The output shaft 14 of the driving motor 3 is connected to the driving gear 12, the left clamping arm is connected to the driving motor 3 connecting shaft, the right clamping arm is also connected to the transmission gear 13 through the connecting shaft, the driving gear 12 and the transmission gear 13 are externally meshed, and the connecting shaft and the corresponding gear can be connected by key connection or friction; the transmission gear 13 is rotatably installed below the fixed seat 2.

[0020] When the driving motor 3 is in working state, the driving motor 3 drives the driving gear 12 to rotate, and then the driving gear 12 drives the transmission gear 13 to rotate, and then drives the connecting shaft to rotate, so that the left and right clamping arms 4 move towards each other or move away from each other, so as to clamp or release the wheel of the bicycle; when the wheel touches the detection pressure plate 10, the sensor 11 receives the signal and transmits it to the controller, controls the action of the driving motor 3, and realizes the grabbing action.

[0021] When the wheel is not pushed into place, the self-lifting clamping structure does not work, thereby preventing the phenomenon of empty grip. After the clamping plate 7 of the clamping arm 4 grabs the wheel of the bicycle 1 from both sides, the driving motor continues to work to make the clamping arm 4 further close. However, at this time, due to the structure of hinged parallel connecting rods between the clamping plate 7 and the clamping arm 4, the clamping plate 7 is no longer closed in the horizontal direction, but is lifted in the vertical direction, thereby lifting the wheel of the bicycle 1 off the ground. During the pushing and moving process of the self-lifting clamping structure, the wheel of the bicycle is lifted and moved by the rolling friction of the rear wheel, which can not only reduce the bearing capacity of the push-pull motor, but also avoid wheel wear and prevent the wheel from slipping due to excessive friction. In addition, the clamping plate 7 is arched, and when the clamping object is the rear wheel of the bicycle, it can avoid protruding parts such as the foot support and the speed change sprocket at the rear wheel.
