Description

Technical Field

[0001] The utility model belongs to the technical field of spinning bikes, and particularly relates to an emergency braking device for a spinning bike. Background Art

[0002] A spinning bike is a very common indoor fitness equipment. Through a spinning bike, fat burning can be achieved quickly. The spinning bike is equipped with a dedicated braking structure. The pedaling damping of the spinning bike is adjusted through the braking structure, and braking is performed through the braking structure when the vehicle speed is too fast to ensure safe use.

[0003] The braking mechanism of the spinning bike in the prior art cannot maintain the braking state. That is, during the braking process, after the brake handle is released, the brake assembly will automatically unlock, which poses certain safety hazards during use. For example, when it is necessary to keep the brake assembly in the braking state in case of an emergency, the user needs to keep operating the handle all the time. However, in an emergency, the user usually cannot keep operating the handle all the time. Therefore, there are certain safety hazards. In addition, since the brake assembly cannot maintain the braking state, the wheels of the spinning bike are prone to rotate during transportation, which is not convenient for transportation. Summary of the Utility Model

[0004] The utility model provides an emergency braking device for a spinning bike, aiming to solve the problem that the spinning bike in the prior art cannot keep the brake assembly in the braking state.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0006] An emergency braking device for a spinning bike, including a frame, a wheel is rotatably arranged on the frame, and a brake assembly for locking or releasing the wheel is further arranged on the frame. The brake assembly includes a handle rotatably connected to the frame.

[0007] The handle includes a release state for controlling the brake assembly to release the wheel and a locking state for controlling the brake assembly to lock the wheel.

[0008] A locking assembly is arranged on the frame. After the handle is converted from the release state to the locking state, the locking assembly keeps the handle in the locking state.

[0009] A further improved scheme: The locking assembly includes a locking hook arranged on the frame and a locking groove arranged on the handle and cooperating with the locking hook.

[0010] Based on the above technical solution: the locking assembly includes a locking hook arranged on the frame and a locking slot that cooperates with the locking hook and is arranged on the handle. When the handle is in a locked state, the locking hook cooperates with the locking slot, and the locking hook will not automatically disengage from the locking slot, thereby keeping the handle in a locked state.

[0011] A further improved solution: the lock hook is rotatably connected to the frame through a bracket, the frame is provided with a magnet, the lock hook is provided with an adsorption block that is adsorbed by the magnet, the magnet is slidably connected to the frame, and the handle is also provided with a pushing block that pushes the magnet so that the magnet and the adsorption block are offset, and an elastic member is provided between the frame and the magnet to push the magnet and the adsorption block to correspond.

[0012] Based on the above technical solution: the lock hook is rotatably connected to the frame through a bracket, a magnet is provided on the frame, and an adsorption block that is attracted to the magnet is provided on the lock hook. When the handle is in the released state, the magnet attracts the adsorption block on the lock hook, so that the lock hook and the handle are staggered, thereby making the operation more convenient when the handle is switched from the released state to the locked state. There is no need to first dislocate the lock hook and the lock slot. Under the action of the magnet, the lock hook and the handle can be automatically dislocated.

[0013] A further improved solution: a slide groove is provided on the frame, and the magnet is slidably connected in the slide groove.

[0014] Based on the above technical solution: a slide groove is provided on the frame, and the magnet is slidably connected in the slide groove. The slide groove can accommodate the magnet, and the slide groove can also guide the magnet, so the magnet has higher displacement accuracy.

[0015] A further improved solution: the elastic member is a spring, one end of the spring is fixed to the magnet, and the other end of the spring is fixed to the frame.

[0016] Based on the above technical solution: the elastic member is a spring, the spring has a simple structure and is easy to process, which reduces the use cost of the elastic member.

[0017] A further improved solution: the handle is provided with a magnetic block for making the lock hook cooperate with the lock slot, and the lock hook is provided with an adsorption body that adsorbs with the magnetic block.

[0018] Based on the above technical solution: the handle is provided with a magnetic block that enables the lock hook to cooperate with the lock slot, and the lock hook is provided with an adsorption body that adsorbs with the magnetic block. The magnetic block and the adsorption body are adsorbed so that the lock hook will not automatically disengage from the lock slot, thereby allowing the handle to remain stably in a locked state.

[0019] Further improved solution: A groove is provided on the locking hook, the adsorbent is bonded in the groove, and a buffer layer is provided between the adsorbent and the magnetic block.

[0020] Based on the above technical solution: A groove is provided on the locking hook, the adsorbent is bonded in the groove, and a buffer layer is provided between the adsorbent and the magnetic block. The buffer layer can prevent the direct contact between the adsorbent and the magnetic block, so that the magnetic block is not easily damaged.

[0021] Further improved solution: The buffer layer is bonded to the magnetic block, or the buffer layer is bonded to the adsorbent.

[0022] Based on the above technical solution: The buffer layer is bonded to the magnetic block, or the buffer layer is bonded to the adsorbent. The setting position of the buffer layer is flexible, so that the buffer layer is easy to assemble.

[0023] Further improved solution: The magnetic block is located between the handle and the push block.

[0024] Based on the above technical solution: The magnetic block is located between the handle and the push block. The setting positions of the magnetic block and the push block are reasonable. The push block first pushes the magnet away, so that the magnetic block and the adsorbent can be effectively adsorbed, and the handle is kept in the locked state.

[0025] Further improved solution: A connecting plate is provided between the handle and the push block, and the magnetic block is bonded to the connecting plate.

[0026] Based on the above technical solution: A connecting plate is provided between the handle and the push block, and the magnetic block is bonded to the connecting plate. The magnetic block is easy to assemble.

[0027] The beneficial effects of the present utility model are as follows:

[0028] By setting the locking assembly in the present utility model, the handle includes a loose state and a locked state. The locking assembly can keep the handle in the locked state, that is, after the handle is switched from the loose state to the locked state, the locking assembly locks the handle to keep the handle in the locked state. Thus, after the operator operates the handle to the locked state in an emergency and then releases the handle, the handle will automatically remain in the locked state, reducing potential safety hazards. In addition, during transportation, the handle can be kept in the locked state, so that the wheels will not rotate automatically during transportation. Description of the Drawings

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the attached drawings in the embodiments of the present utility model. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0037] Referring to Figures 1 to 4 , an emergency braking device of a spinning bike includes a frame 1, on which wheels 2 are rotatably provided, and a braking component 3 for locking or releasing the wheels 2 is also provided on the frame 1. The braking component 3 includes a handle 4 rotatably connected to the frame 1;

[0038] The handle 4 includes a release state for controlling the braking component 3 to release the wheels 2 and a locking state for controlling the braking component 3 to lock the wheels 2;

[0039] The frame 1 is provided with a locking assembly 5 , and after the handle 4 is converted from the released state to the locked state, the locking assembly 5 keeps the handle 4 in the locked state.

[0040] The wheel 2 can be rotatably connected to the frame 1 in any manner, and a rolling bearing can be provided between the wheel 2 and the frame 1 .

[0041] The frame 1 is also provided with a pedal assembly, which drives the wheel 2 to rotate.

[0042] The locking assembly 5 includes a locking hook 51 provided on the frame 1 and a locking slot 52 provided on the handle 4 and cooperating with the locking hook 51. When the locking hook 51 is elastic, the elastic force of the locking hook 51 can be overcome to enable the locking hook 51 to engage with or disengage from the locking slot 52.

[0043] refer to Figures 1 to 4 Specifically: the locking hook 51 is rotatably connected to the frame 1 through the bracket 53, the frame 1 is provided with a magnet 54, the locking hook 51 is provided with an adsorption block 55 adsorbed by the magnet 54, the magnet 54 is slidably connected to the frame 1, and the handle 4 is further provided with a pushing block 41 for pushing the magnet 54 so that the magnet 54 is staggered from the adsorption block 55, and an elastic member 57 is provided between the frame 1 and the magnet 54 to push the magnet 54 and the adsorption block 55 to correspond.

[0044] The frame 1 is provided with a slide groove, and the magnet 54 is slidably connected in the slide groove.

[0045] The elastic member 57 is a spring, one end of which is fixed to the magnet 54 , and the other end of which is fixed to the frame 1 .

[0046] When the handle 4 is switched from the released state to the locked state, the lock hook 51 should be offset from the handle 4 to prevent interference between the handle 4 and the lock hook 51, which would cause inconvenience in operation. Therefore, by providing a magnet 54 and an adsorption block 55, the magnet 54 can maintain the lock hook 51 and the handle 4 in an offset state through the adsorption block 55, thereby making the handle 4 easier to operate.

[0047] The handle 4 is provided with a magnetic block 58 for matching the locking hook 51 with the locking slot 52 , and the locking hook 51 is provided with an adsorption body 59 for adsorbing the magnetic block 58 .

[0048] refer to Figures 1 to 4 Specifically, a groove is provided on the locking hook 51 , the adsorption body 59 is bonded into the groove, and a buffer layer is provided between the adsorption body 59 and the magnetic block 58 .

[0049] The buffer layer is bonded to the magnetic block 58 , or the buffer layer is bonded to the adsorption body 59 .

[0050] Specifically, the magnetic block 58 is located between the handle 4 and the push block 41 .

[0051] A connecting plate is provided between the handle 4 and the pushing block 41 , and the magnetic block 58 is bonded to the connecting plate.

[0052] The handle 4 and the connecting plate are an integrated structure, and the connecting plate and the pushing block 41 are an integrated structure.

[0053] The handle 4 can be rotatably connected to the frame 1 via a rotating shaft.

[0054] The working principle of this embodiment is as follows:

[0055] When the handle 4 is in the released state, the push block 41 is out of contact with the magnet 54, and the spring pushes the magnet 54 to move, so that the magnet 54 corresponds to the adsorption block 55. After the magnet 54 corresponds to the adsorption block 55, the magnet 54 is adsorbed by the adsorption block 55. At this time, the lock hook 51 rotates, so that the lock hook 51 and the handle 4 are staggered.

[0056] When the handle 4 is converted from the loose state to the locked state, the push block 41 first pushes the magnet 54 to move, so that the magnet 54 is staggered with the adsorption block 55. At this time, the lock hook 51 loses the adsorption force of the magnet 54. Then, the handle 4 continues to rotate. When the handle 4 rotates to the locked state, the magnetic block 58 corresponds to the adsorption body 59. At this time, the magnetic block 58 and the adsorption body 59 are adsorbed, so that the lock hook 51 cooperates with the lock slot 52, and the handle 4 is locked in the locked state.

[0057] When the handle 4 is converted from the locked state to the released state, the adsorption force of the magnetic block 58 is overcome and the handle 4 can be restored to the released state. At the same time, the magnet 54 returns to its original position under the action of the spring, and the lock hook 51 is in a state of being staggered with the handle 4.

[0058] The present invention is not limited to the above optional implementation methods. Under the premise of not conflicting with each other, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the scope of protection of the present invention.
