Description

Technical Field

[0001] This application relates to the field of bicycles, and more particularly to a rear wheel fixing mechanism for a bicycle. Background Technology

[0002] In various scenarios, when bicycles are not in use, it is difficult to secure the bicycle wheels, making parking inconvenient. Therefore, a bicycle rear wheel securing mechanism is needed to solve these problems.

[0003] Patent document CN206871229U discloses a bicycle fixing mechanism for a bicycle parking device, including a base and a clamping mechanism mounted on the base. The clamping mechanism includes a first clamping plate, a second clamping plate, and a clamping control mechanism. The first and second clamping plates are arranged opposite to each other, with a first spring between the first clamping plate and the base, and a second spring between the second clamping plate and the base. The clamping control mechanism includes a first hinge block, a second hinge block, a locking block, a control lever, and a locking spring. The control lever is connected to the locking block, and the locking block has a locking head that locks the first and second hinge blocks in a flattened state. The locking spring is mounted on the control lever, and its elastic force causes the locking head of the locking block to lock the first and second hinge blocks. This bicycle fixing mechanism reliably fixes bicycles and is easy to operate, making it particularly suitable for use in multi-level bicycle parking devices.

[0004] However, the bicycle fixing mechanism of the above-mentioned bicycle parking device cannot provide multiple fixations for the rear wheel, resulting in unstable rear wheel fixation and the inability to fix rear wheels of different sizes. Therefore, we propose a bicycle rear wheel fixing mechanism to solve the above problems. Utility Model Content

Therefore, this invention proposes a rear wheel fixing mechanism for bicycles.

[0006] The technical solution for a bicycle rear wheel fixing mechanism provided in this application is as follows:

[0007] A rear wheel fixing mechanism for a bicycle includes a first housing, a first motor disposed on the left inner wall of the first housing, a second motor disposed on the rear side of the first housing, and a wheel disposed on the top of the first housing. The first motor is used to clamp the wheel, and the second motor is used to clamp the sides of the wheel. The wheel is used to demonstrate the use of the mechanism. It also includes:

[0009] A first clamping assembly is disposed in the first housing;

[0010] The second clamping assembly is disposed on the first housing.

[0011] Furthermore, the first clamping assembly includes a first motor, which is fixedly connected to the left inner wall of the first housing. The output shaft of the first motor is fixedly connected to a first transmission shaft, and one end of the first transmission shaft is fixedly connected to two worm gears.

[0012] Furthermore, each of the two worm gears is meshed with a worm wheel, and each of the two worm wheels is fixedly connected to a second drive shaft, which is rotatably connected to the inner wall of the first housing.

[0013] Furthermore, one end of each of the two second drive shafts is fixedly connected to a gear, and each of the two gears is meshed with a rack. The front sides of the two racks are slidably connected to the inner front wall of the first housing.

[0014] Furthermore, a connecting rod is fixedly connected to the top of each of the two racks, and a universal joint is fixedly connected to the top of each of the two connecting rods.

[0015] Furthermore, a first clamping plate is fixedly connected to the top of each of the two universal joints, and a rotating shaft is fixedly connected to one end of each of the two first clamping plates. The two rotating shafts are rotatably connected to the top of the fixed block.

[0016] Furthermore, the second clamping assembly includes a second housing, which is fixedly connected to the top of the first housing, and the rear side of the second housing is fixedly connected to the second motor.

[0017] Furthermore, the output shaft of the second motor is fixedly connected to a bidirectional threaded rod, and both ends of the bidirectional threaded rod are threadedly connected to threaded sleeves, with a second clamping plate fixedly connected to the top of each of the two threaded sleeves.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 2. This solution can fix rear wheels of different sizes. The two universal joints drive the two first clamping plates to move respectively. The two first clamping plates clamp the left sides of the wheel. And through the control of the first motor, the clamping of wheels of different sizes can be adjusted. Attached Figure Description

[0029] Two auxiliary ramps 2 are fixedly connected to the left and right sides of the first box 1 respectively, and a fixing block 3 is fixedly connected to the top of the first box 1. A placement groove 4 is provided on the fixing block 3, and a wheel 5 is placed in the placement groove 4.

[0030] The first clamping assembly is disposed in the first housing 1;

[0031] The second clamping component is disposed in the first housing 1.

[0032] Specifically, the first clamping assembly includes a first motor 6, and the first motor 6 is fixedly connected to the left inner wall of the first housing 1. The output shaft of the first motor 6 is fixedly connected to a first transmission shaft 7, and one end of the first transmission shaft 7 is fixedly connected to two worm gears 8.

[0033] Specifically, each of the two worm gears 8 is meshed with a worm wheel 9, and each of the two worm wheels 9 is fixedly connected to a second drive shaft 10. The two second drive shafts 10 are rotatably connected to the inner wall of the first housing 1.

[0034] Specifically, one end of each of the two second drive shafts 10 is fixedly connected to a gear 11, and each of the two gears 11 is meshed with a rack 12. The front sides of the two racks 12 are slidably connected to the inner wall of the front side of the first housing 1.

[0035] Specifically, a connecting rod 13 is fixedly connected to the top of each of the two racks 12, and a universal joint 14 is fixedly connected to the top of each of the two connecting rods 13.

[0036] Specifically, the top of each of the two universal joints 14 is fixedly connected to a first clamping plate 15, and one end of each of the two first clamping plates 15 is fixedly connected to a rotating shaft, and the two rotating shafts are rotatably connected to the top of the fixed block 3.

[0037] Specifically, the second clamping assembly includes a second housing 16, which is fixedly connected to the top of the first housing 1, and the rear side of the second housing 16 is fixedly connected to the second motor 17.

[0038] Specifically, the output shaft of the second motor 17 is fixedly connected to a bidirectional threaded rod 18, and both ends of the bidirectional threaded rod 18 are threadedly connected to threaded sleeves 19, and the tops of the two threaded sleeves 19 are fixedly connected to a second clamping plate 20.

[0039] The implementation principle of a bicycle rear wheel fixing mechanism according to an embodiment of this application is as follows: First, the wheel 5 is moved via the auxiliary ramp 2, so that the wheel 5 can be easily moved onto the fixing block 3. Then, the wheel 5 is moved into the placement groove 4, which can initially limit the wheel 5 and prevent it from moving. Then, the first motor 6 is started, which drives the first drive shaft 7 to rotate. The first drive shaft 7 drives the two worm gears 8 to rotate, and the two worm gears 8 drive the two worm wheels 9 to rotate. The two worm wheels 9 drive the two second drive shafts 10 to rotate, and the two second drive shafts 10 drive the two gears 11 to rotate.

The two universal joints 14 then drive two first clamping plates 15 to move. The two first clamping plates 15 clamp the left sides of the wheel 5. Under the control of the first motor 6, the clamping of wheels of different sizes can be adjusted. Then, the second motor 17 is started, which drives the bidirectional threaded rod 18 to rotate.
