DETAILED DESCRIPTION

[0029] In order to facilitate understanding of the utility model, the utility model will be described more comprehensively and in detail in the following in combination with the drawings of the specification and the preferred embodiments, but the protection scope of the utility model is not limited to the following specific embodiments.

[0030] As Figures 1 to 6As shown, the water droplet wheel electronic brake brake force double adjusting device provided by the embodiment mainly comprises a wire cup assembly 1, a wire wheel seat 2, a cover plate 3, an adjusting operation unit 4 and a magnetic brake assembly 5. The magnetic brake assembly 5 comprises an induction magnet 51 fixed on the wire cup assembly 1, and an induction coil 52 and an electric control board 53 installed inside the wire wheel seat 2. When throwing, the rotating induction magnet 51 generates an induced current in the induction coil 52, and the electric control board 53 realizes electromagnetic braking of the wire cup by controlling the induced current loop.

[0031] The cover plate 3 is fixed on the side of the wire wheel seat 2, and two first circular arc grooves 31 and second circular arc grooves 32 are formed on the cover plate 3. The two first circular arc grooves 31 and second circular arc grooves 32 are through and concentrically arranged, and the radii of the two are different.

[0032] The adjusting operation unit 4 comprises a first operation unit 41 and a second operation unit 42 which independently operate, and are respectively used for gear adjusting and stepless fine adjusting of brake force.

[0033] The structure and working principle of the first operation unit 41 (gear adjusting) are as follows:

[0034] The unit comprises a gear adjusting rotating ring 411, a first operation rod 412 and a push piece 413. The gear adjusting rotating ring 411 is rotatably sleeved on the positioning column 33 integrally formed on the inner wall of the cover plate 3 through the shaft hole in the middle of the gear adjusting rotating ring 411. The first operation rod 412 is fixed on the upper end face of the gear adjusting rotating ring 411 and extends out of the cover plate 3 from the first circular arc groove 31. Pushing the first operation rod 412 can drive the entire gear adjusting rotating ring 411 to rotate around the positioning column 33. The push piece 413 is vertically fixed on the bottom end of the gear adjusting rotating ring 411. The top cover 21 of the wire wheel seat 2 is provided with a give way groove 22 matched with the movement track of the push piece 413. Two push switches 54 (such as touch switches) are linearly arranged on the electric control board 53 opposite the give way groove 22. When the gear adjusting rotating ring 411 is rotated, the push piece 413 swings and triggers different push switches 54 in turn. The electric control board 53 switches to the preset corresponding brake force gear according to the triggered switch.

[0035] The structure and working principle of the second operation unit 42 (fine adjusting) are as follows:

[0036] The unit includes a fine adjustment rotating ring 421, a second operating lever 422 and a signal magnet 423. The fine adjustment rotating ring 421 is accommodated in the space surrounded by the limiting ring wall 35 on the inner side wall of the cover plate 3, and is in concentric nested relationship with the gear adjustment rotating ring 411. The second operating lever 422 is fixed on the upper end face of the fine adjustment rotating ring 421 and extends out of the cover plate 3 from the second circular arc groove 32. Pushing the second operating lever 422 can drive the fine adjustment rotating ring 421 to rotate. The signal magnet 423 (preferably a permanent magnet) is embedded on the lower end face of the fine adjustment rotating ring 421. On the electric control board 53, a magnetic signal sensor 55 (preferably a Hall sensor) is arranged corresponding to the rotating track of the signal magnet 423. When the fine adjustment rotating ring 421 is rotated, the relative distance between the signal magnet 423 and the magnetic signal sensor 55 will change, resulting in a change in the magnetic field strength. The magnetic signal sensor 55 converts this change into an electric signal and transmits it to the electric control board 53, which continuously and steplessly finely adjusts the brake force according to the signal.

[0037] Finally, the electric control board 53 comprehensively processes the gear signal from the toggle switch 54 and the fine adjustment signal from the magnetic signal sensor 55, accurately controls the current of the induction coil 52 through a set of integrated control algorithms, so as to realize the brake force output covering a wide range of gears and fine adjustment.

[0038] To further optimize the structural performance and operation experience, the embodiment also provides the following auxiliary structures:

[0039] To prevent excessive rotation, a first limiting protrusion 414 is arranged on the circumferential wall of the gear adjustment rotating ring 411, and a second limiting protrusion 424 is arranged on the circumferential wall of the fine adjustment rotating ring 421. Correspondingly, a first limiting bar 34 is arranged on the outer circumferential side of the positioning column 33 of the inner side wall of the cover plate 3, and a second limiting bar 36 is arranged on the inner circumferential side of the limiting ring wall 35. The first limiting protrusion 414 cooperates with the first limiting bar 34 to limit the rotation arc of the gear adjustment rotating ring 411; similarly, the second limiting protrusion 424 cooperates with the second limiting bar 36 to limit the rotation arc of the fine adjustment rotating ring 421.

[0040] To make the gear adjustment have a clear jerk feeling, a plurality of positioning recesses 415 (which can be spherical concave pits or radial strip-shaped grooves) are processed on the upper end face of the gear adjustment rotating ring 411 in a circumferential direction. A resilient positioning assembly 6 is installed on the inner side wall of the cover plate 3, and the spring inside the resilient positioning assembly 6 always pushes a positioning head (such as a steel ball) against the upper end face of the gear adjustment rotating ring 411. When rotating, the positioning head will slide out of one positioning recess 415, slide across the ring surface, and then be clamped into the next positioning recess 415, thereby producing obvious gear positioning touch feeling and damping.

[0041] An O-shaped sealing ring 7 is pressed between the upper end surface of the fine adjustment rotating ring 421 and the inner side wall of the cover plate 3. The sealing ring realizes radial dynamic sealing between the fine adjustment rotating ring 421 and the cover plate 3, effectively preventing water and dust, and the friction force generated after the sealing ring is compressed provides uniform and smooth damping for the rotation of the fine adjustment rotating ring 421, improving the hand feeling of the fine adjustment operation.

[0042] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
