Description

Technical Field

[0001] This utility model belongs to the field of brake structure technology, and in particular relates to a brake structure for a stationary bicycle. Background Technology

[0002] Spin bikes, also known as exercise bikes, have become an increasingly popular fitness equipment among fitness enthusiasts because they overcome many of the drawbacks of outdoor riding.

[0003] Because it lacks the one-way ratchet mechanism of a regular bicycle, the flywheel of a stationary bike continues to spin for a period of time due to inertia after the rider stops pedaling. Typically, users need to increase the resistance using the stationary bike's resistance adjustment system to slow the flywheel's rotation until it stops. However, due to the slow transmission speed, immediate stopping is not possible, posing a safety risk. Utility Model Content

[0004] The technical problem this invention aims to solve is that the flywheel speed slows down until it stops rotating. Due to the slow transmission speed, it is impossible to stop immediately, which poses a safety risk.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a dynamic bicycle brake structure, including a square box and a brake disc, wherein the bottom of the square box is open, the brake disc is rotatably connected between the inner walls of the square box, and a braking component is also included, wherein the braking component is disposed inside the square box, and the rotation of the brake disc is quickly and effectively stopped by the braking component.

[0006] Furthermore, the braking assembly includes a bidirectional screw, an adjusting block, a connecting frame, a clamping plate, a side frame, and a limiting post, wherein:

[0007] The bidirectional screw is rotatably connected between the inner walls of the square box. The adjusting block passes through the bidirectional screw and is threadedly connected to it, and is symmetrically distributed relative to the brake disc. The connecting frame is fixedly connected to the bottom of the adjusting block. The clamping piece is fixedly connected to the bottom of the connecting frame. The side frame is fixedly connected to the inner wall of the square box and is symmetrically distributed relative to the brake disc. The limiting post is fixedly connected to the outer wall of the clamping piece, and one end of it horizontally passes through the side frame and is slidably connected to it.

[0008] Furthermore, the braking assembly also includes a top frame, an electric push rod, and a pressure plate, wherein:

[0009] The top frame is fixedly connected to the top of the box, the electric push rod is fixedly connected to the bottom of the top frame, the pressure plate is fixedly connected to the free end of the electric push rod, and a servo motor is fixedly installed on the outer wall of the box, with its output end fixedly connected to one end of a bidirectional screw.

[0010] Furthermore, the side frame is C-shaped, and the bottom of the pressure plate is arc-shaped.

[0011] Furthermore, the brake disc is provided with heat dissipation holes, which are evenly distributed.

[0012] With the above structure, the beneficial effects of this utility model are as follows: the rotation of the bidirectional screw can cause the two sets of clamping plates to move relative to each other under the limiting and guiding action of the side frame and the limiting post, clamping both sides of the brake disc, and the downward pressure of the pressure plate can stop the rotation of the brake disc as soon as possible, speeding up the stopping speed and reducing safety hazards.

[0019] like Figure 1-2 As shown, a braking structure for a stationary bike includes a box 1 and a brake disc 2. The bottom of the box 1 is open, and the brake disc 2 is rotatably connected to the inner wall of the box 1. It also includes a braking assembly located inside the box 1.

[0020] like Figure 1-4As shown, in order to quickly and effectively stop the rotation of the brake disc 2, the braking assembly includes a bidirectional screw 3, an adjusting block 4, a connecting frame 5, a clamping plate 6, a side frame 7, a limiting post 8, a top frame 9, an electric push rod 10, and a pressure plate 11. The bidirectional screw 3 is rotatably connected between the inner walls of the square box 1. The adjusting block 4 passes through the bidirectional screw 3 and is threadedly connected to it, and it is symmetrically distributed relative to the brake disc 2. The connecting frame 5 is fixedly connected to the bottom of the adjusting block 4. The clamping plate 6 is fixedly connected to the bottom of the connecting frame 5. The side frame 7 is fixedly connected to the inner wall of the square box 1, and it is symmetrically distributed relative to the brake disc 2. The limiting post 8 is fixedly connected to the outer wall of the clamping plate 6, and one end of it horizontally passes through the side frame 7 and is slidably connected to it. The top frame 9 is fixedly connected to the top of the square box 1. The electric push rod 10 is fixedly connected to the bottom of the top frame 9. The pressure plate 11 is fixedly connected to the free end of the electric push rod 10. A servo motor 12 is fixedly installed on the outer wall of the square box 1, and its output end is fixedly connected to one end of the bidirectional screw 3.

[0021] Among them, the side frame 7 is C-shaped, the bottom of the pressure plate 11 is arc-shaped, and the brake disc 2 is provided with heat dissipation holes 13, which are evenly distributed.

[0022] In practical use, the central axis of the brake disc 2 is coaxial with the central axis of the flywheel on the exercise bike. The servo motor 12 and the electric push rod 10 are controlled by an external controller, which can be installed on the handlebars of the exercise bike. When it is necessary to stop the flywheel, the servo motor 12 runs to rotate the bidirectional screw 3. The two sets of clamping plates 6 move relative to each other under the limiting and guiding action of the side frame 7 and the limiting post 8, clamping the two sides of the brake disc 2. At the same time, the electric push rod 10 is extended. With the pressing of the pressure plate 11, the rotation of the brake disc 2 can be stopped as quickly as possible, the stopping speed can be accelerated, and the safety hazards can be reduced.
