detailed description

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

Gravity clutch device: (See Fig. 1 to Fig. 6) The device automatically controls whether to charge the battery according to the condition of the bicycle running. It includes a mounting bracket 11 and a clip 111, a self-locking mechanism 12, a jack 13 and a weight bar 14; the mounting bracket 11 is fixed to the rear frame 71 of the bicycle by a clip 111.

The self-locking mechanism 12 is fixed to the mounting frame 11 (see FIGS. 6 and 7); the self-locking mechanism includes a slider 121, a steel ball 122, and a spring 123. In the illustrated state, the slider 121 can only move to the left. This is because the steel ball 122 presses the slider 121 against the wedge slit 129, so the slider 121 cannot move to the right, thereby forming a self-locking state. However, if one end of the jack 13 pushes the steel ball toward the spring 123, the steel ball 122 no longer presses the slider 121, and the slider 121 can move to the right. The movement of the jack 13 is controlled by the weight bar 14. The weight bar 14 is hinged to the second shaft 19 on the mounting frame 11, and the upper portion of the weight bar 14 is in intermittent contact with the jack 13.

The battery 3 is disposed on the clip 111.

Referring to Figures 1, 3 and 8, the drive unit 2 includes a friction wheel 41, a governor 42, a generator 43, and a bracket 21, and the friction wheel 41 is coupled to the generator 43 via a governor 42; if necessary, the friction wheel 41 In contact with the rear wheel 72 of the bicycle, from The rear wheel 72 of the bicycle drives the friction wheel 41 and the generator 43 to rotate. The electric power generated by the generator 43 is input to the battery 3 through the wire 35 to charge the battery 3.

The upper portion of the bracket 21 of the driving device 2 is hinged with the first support shaft 28 on the mounting frame 11 (see Figs. 1, 2 and 8); a portion of the lower portion of the bracket 21 is fixedly connected to the governor 42, and the other portion of the lower portion of the bracket 21 is The outer casing 44 of the generator 43 is fixed; that is, the components of the drive unit 2 are mounted on the bracket 21, and the bracket 21 is rotated about the first support shaft 28 on the mounting frame 11, and the entire drive unit 2 is also rotated.

The bracket 21 is also coupled to the self-locking mechanism 12; thus, the self-locking mechanism 12 can control the drive unit 2 by controlling the bracket 21. A sliding slot 211 (see FIG. 3) is disposed on the bracket 21, and the slider 121 of the self-locking mechanism 12 is provided with a round pin 1211, and the round pin 1211 is located in the sliding slot 211. When the bracket 21 is rotated, the slider 121 is moved by the round pin 1211. Alternatively, when the slider 121 is fixed, the control bracket 21 does not rotate.

How to use the above device:

Referring to FIG. 4 and FIG. 5, during the uphill running of the bicycle, the driving device 2 and the weight bar 14 are freely perpendicular under the action of gravity, and the angle between the bracket 21 of the driving device and the clip 111 of the mounting bracket is greater than 90°, and the friction thereof is The wheel 41 is in a separated state from the rear wheel 72 of the bicycle.

Referring to FIG. 6 and FIG. 7, during the downhill running of the bicycle, the driving device 2 rotates around the first support shaft 28 under the action of gravity, and the angle between the bracket 21 and the clip 111 of the mounting bracket is less than 90°, and the friction wheel thereof 41 is in contact with the rear wheel 72 of the bicycle and is driven by the rear wheel 72 of the bicycle; when the rear wheel 72 of the bicycle is shaken during running, the friction wheel 41 has a tendency to leave the rear wheel 72. At this time, the self-locking mechanism 12 prevents the friction wheel 41 from being separated from the rear wheel 72, that is, the bracket 21 is moved to the right by the round pin 1211 to slide the slider 121, but since the slider 121 is pressed against the wedge by the steel ball 122 In 129, the lock bracket 21 is thus prevented from rotating, so that the friction wheel 41 continues to be in contact with the rear wheel 72 and is driven by the rear wheel 72. The friction wheel 41 drives the generator 43 to generate electricity through the governor 42, and the generated electricity is input to the battery 3 through the wire 35 to charge the battery 3.

Referring to FIG. 9 and FIG. 10, when the bicycle is traveling on the ground, the weight bar 14 rotates in the opposite direction of the rear wheel 72 about the second support shaft 19 under the action of gravity, and the weight bar 14 is clamped to the clip 111 of the mounting frame. The angle is a right angle, and the upper portion of the weight rod 14 pushes the ram 13 which pushes the steel ball 122 in the self-locking mechanism 12, so that the slider 121 in the self-locking mechanism 12 is no longer pressed, the slider 121 and The brackets 21 are released together, so that the bracket 21 rotates in the opposite direction of the first support shaft 28 toward the rear wheel 72 under the action of gravity, and the angle between the bracket 21 and the clip 111 of the mounting bracket is a right angle, and the friction wheel of the driving device 2 The 41 is separated from the rear wheel 72 such that the generator 43 stops generating electricity.

Another implementation method: for a good physical rider, the battery can also be charged by the present invention when driving on a flat road. The method is to adjust the friction wheel 41 to contact with the rear wheel 72 on the ground (see Fig. 11), and then fix the clip 111 to the rear frame 71. In this way, the bicycle can be charged while the bicycle is driving downhill and on the road. On the uphill, the friction wheel 41 is separated from the rear wheel 72 and no longer consumes the rider's physical strength.
