[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] As described in the background section, traditional bicycle boosters are prone to lateral movement during use, and the force transmission between the training wheel and the bicycle tire is not stable enough, which reduces the rider's riding safety. When installing traditional boosters, they tend to encroach on the position of the mudguard, and when the bicycle is wading through water, mud and water can easily splash onto the rider's clothing through the rear wheel.

[0019] To solve this technical problem, this utility model provides a bicycle booster.

[0020] For details, please refer to Figures 1-4 A bicycle booster specifically includes: a connecting frame 1, a power component mounted on the connecting frame 1, and a connecting component at one end of the connecting frame 1. The power assembly includes a motor 5, a drive shaft 6, bearings 7, a driven shaft 8, and a belt 9. The motor 5 is fixed to the inner side of one side of the connecting frame 1. The drive shaft 6 is fixed to the output end of the motor 5. The drive shaft 6 is rotatably connected to the connecting frame 1. Bearings 7 are fixed to both sides of the inner side of the connecting frame 1 away from the drive shaft 6. A driven shaft 8 is fixed to the inner side of the two bearings 7. The driven shaft 8 is rotatably connected to the connecting frame 1. The drive shaft 6 and the driven shaft 8 are connected by a belt 9.

[0021] This utility model provides a bicycle booster equipped with two driven wheels. The driven wheels clamp the two sides of the bicycle tire, limiting the lateral movement of the booster relative to the bicycle, reducing the risk of lateral movement of the bicycle booster, and making the force transmission between the driven wheels and the bicycle tire more stable, thus ensuring the rider's riding safety.

[0022] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] Reference Figures 1-4 A bicycle power assist device includes a connecting frame 1, a power component mounted on the connecting frame 1, and a connecting component at one end of the connecting frame 1. The power assembly includes a motor 5, a drive shaft 6, bearings 7, a driven shaft 8, and a belt 9. The motor 5 is fixed to the inner side of one side of the connecting frame 1. The motor 5 is a Bosch Active Line motor. The output end of the motor 5 is fixed to the drive shaft 6, which is rotatably connected to the connecting frame 1. Bearings 7 are fixed to both sides of the inner side of the connecting frame 1 away from the drive shaft 6. A driven shaft 8 is fixed to the inner side of the two bearings 7. The driven shaft 8 is rotatably connected to the connecting frame 1. The drive shaft 6 and the driven shaft 8 are connected by a belt 9.

[0025] Both ends of the driven shaft 8 are provided with driven wheels 10. A vertical side edge is added to one side of the driven wheel 10, which clamps the two sides of the bicycle tire, thereby limiting the lateral movement of the power assist relative to the bicycle. At the same time, the side of the driven wheel 10 away from the side edge adopts a concave design. The concave design allows the driven wheel to fit the bicycle tire more closely, resulting in higher transmission efficiency and more significant power assist effect. Both sides of the outer side of the driven shaft 8 are slidably connected with retaining rings 11. The retaining rings 11 are located on one side of the driven wheel 10 and are engaged with the driven wheel 10. Both sides of the driven shaft 8 are threadedly connected with nuts 12.

[0026] The connecting assembly includes a connecting plate 2, rivets 3 and a retaining ring 4. One end of the connecting frame 1 is fixed with the connecting plate 2. Two rivets 3 are fixed on the inner side of one side of the connecting plate 2. The two rivets 3 are distributed vertically. The outer side of the top of the rivet 3 is rotatably connected to the retaining ring 4.

[0027] A rubber sheet 13 is fixed to the inner side of the retaining ring 4; a protective shell 14 is provided on the outer side of the drive shaft 6, driven shaft 8 and belt 9, and the protective shell 14 is fixedly connected to the connecting frame 1; the outer side of the connecting frame 1, connecting plate 2 and retaining ring 4 are all sprayed with anti-rust paint; a power supply matching the motor 5 is provided on the outer side of the bicycle, and the matching power supply is fixed on the bicycle.

[0028] The bicycle booster provided by this utility model is used as follows: the connecting frame 1 is fixedly connected to the connecting plate 2, and the fixing ring 4 is connected to the connecting plate 2 by the rivet 3, so that the connecting plate 2 and the fixing ring 4 can be opened and closed. The booster can be fixed on the frame by connecting the fixing ring 4 and the connecting plate 2 by the knob. The booster is located above the front of the bicycle tire, below the mudguard. When riding in the rain or on muddy or wet roads, the rider's clothes are less likely to get dirty from the mud and water splashed by the wheels, resulting in a better riding experience. The motor 5 provides power to drive the drive shaft 6 to rotate, and the power is transmitted to the driven shaft 8 through the belt 9. The driven shaft 8 is fixed to the driven wheel 10 by the retainer 11 and the nut 12, so that the driven wheel 10 and the driven shaft 8 rotate together. The concave side of the driven wheel 10 can partially wrap around the tire, and can provide power in two lateral directions and in the normal direction of the tire, so as to save the rider's energy and achieve the effect of assisting. Since the driven wheel 10 needs to contact the bicycle tire, the contact surface between the driven wheel and the tire is designed with a concave surface, which makes the contact between the driven wheel 10 and the bicycle tire more secure, thereby obtaining better transmission and assist effects.

[0029] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to specific implementations. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
