Description

Technical Field

[0001] This utility model relates to the field of bicycle handlebar technology, specifically a bicycle folding handlebar. Background Technology

[0002] Bicycle handlebars are an important control component of a bicycle. They are usually installed at both ends of the handlebars at the front of the frame and are arranged laterally. The handlebars are held by the rider, and turning the handlebars changes the direction of the wheels, thus achieving the steering function. The handlebars are made of various materials, such as aluminum alloy and carbon fiber, with different weights, strengths, and feel characteristics to meet the rider's control needs and comfort in different scenarios. Accessories such as brake levers can also be installed on the handlebars to further integrate the operation functions during riding. They are the key hub for communication between the rider and the bicycle.

[0003] Existing bicycle handlebars are typically rigidly connected to the frame by welding. The overall structural design focuses on strength and stability. When carrying a bicycle on public transportation, putting it in a car trunk, or storing it in a small space, the overall size cannot be reduced by folding the handlebars. This is especially true for urban commuters or users who frequently need to move their vehicles, as the inconvenience of carrying the bicycle may reduce its usability. Non-foldable handlebars limit the bicycle's flexible storage and transportation efficiency, making it difficult to meet diverse usage needs. Therefore, we propose a bicycle folding handlebar. Utility Model Content

A pin is slidably inserted into the arc surface of the frame, and a pull ring is fixedly connected to one end of the pin. A circular plate is rotatably connected to the inner wall of the frame. The handle body is fixedly connected to the surface of the circular plate. The arc surface of the circular plate is provided with several circular grooves, and the size of the pin is adapted to the size of the circular grooves.

[0006] The effect achieved by the above components is that by setting up a folding structure, it is easy to fold the handlebar body when carrying the bicycle, thereby reducing the space occupied when carrying the bicycle and making it easier to fold and carry the bicycle.

[0007] Preferably, a spring is fitted onto the arc surface of the pin, and the two ends of the spring are fixedly connected to the pin and the frame, respectively.

[0008] The effect achieved by the above components is that the spring improves the stability of the pin inserted into the groove, thereby preventing the pin from coming out of the groove due to shaking.

[0015] Preferably, a plurality of anti-slip strips are fixedly connected to the arc surface of the handle body, and the anti-slip strips are made of rubber.

[0016] The effect achieved by the above components is that the rubber anti-slip strips on the surface of the handle increase grip friction without affecting the airflow through the round hole, thus combining anti-slip and heat dissipation functions.

[0017] Preferably, the inner wall of the air collection duct is fixedly connected with several filter plates.

[0018] The effect achieved by the above components is that the filter plate on the inner wall of the air collection duct can filter dust and impurities in the air, prevent foreign objects from entering the ventilation slot and clogging the air holes or contaminating the internal structure, and ensure the long-term stable operation of the heat dissipation system.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-2This utility model provides a technical solution: a bicycle folding handlebar, including a handlebar 1 and two handlebar bodies 2. The surface of the handlebar 1 is provided with a folding structure 3. By setting the folding structure 3, it is easy to fold the handlebar bodies 2 on the handlebar 1 when carrying the bicycle, thereby reducing the space occupied when carrying the bicycle and making it easier to fold and carry the bicycle. The surface of the handlebar body 2 is provided with a heat dissipation structure 4. By setting the heat dissipation structure 4, during riding, external air enters the air inlet pipe 43 through the air collection pipe 44, and then flows into the ventilation groove 41 inside the handlebar body 2. After absorbing the heat generated by gripping the handlebar, it is discharged through the round hole 42 on the arc surface of the handlebar, forming an air circulation to reduce the handlebar temperature and improve grip comfort.

[0029] Reference Figure 3 and Figure 4 As shown in this embodiment: the folding structure 3 includes two frames 31, both of which are fixedly connected to both ends of the handlebar 1. A pin 32 is slidably inserted into the arc surface of the frame 31, and a pull ring 33 is fixedly connected to one end of the pin 32. A circular plate 34 is rotatably connected to the inner wall of the frame 31. The handlebar body 2 is fixedly connected to the surface of the circular plate 34. Several circular grooves 35 are formed on the arc surface of the circular plate 34, and the size of the pin 32 matches the size of the circular grooves 35. A spring 36 is fitted onto the arc surface of the pin 32, and both ends of the spring 36 are fixedly connected to the pin 32 and the frame 31 respectively. The spring 36 improves the stability of the pin 32 inserted into the circular groove 35, thereby preventing the pin 32 from dislodging from the groove 35 due to shaking. Several ball bearings 37 are rotatably connected to the inner wall of the frame 31. The ball bearings 37 on the inner wall of the frame 31 reduce the friction when the circular plate 34 rotates, making the adjustment process smoother. Several scale bars 38 are fixedly connected to the surface of the circular plate 34, and a pointer 39 is fixedly connected to the surface of the frame 31. The scale bars 38 on the surface of the circular plate 34 and the pointer 39 on the frame 31 cooperate to accurately position the handle angle.

[0030] Reference Figure 5As shown, specifically, the heat dissipation structure 4 includes a ventilation slot 41, which is located at one end of the handle body 2. The arc surface of the handle body 2 has several circular holes 42, and the ventilation slot 41 communicates with these holes 42. An air inlet pipe 43 is fixedly connected to one end of the handle body 2, and the air inlet pipe 43 communicates with the ventilation slot 41. The end of the air inlet pipe 43 furthest from the handle body 2 is connected to a collecting pipe 44. Several anti-slip strips 45, made of rubber, are fixedly connected to the arc surface of the handle body 2. These rubber anti-slip strips increase grip friction without affecting the airflow from the circular holes 42, thus combining anti-slip and heat dissipation functions. Several filter plates 46 are fixedly connected to the inner wall of the collecting pipe 44. These filter plates 46 filter dust and impurities from the air, preventing foreign objects from entering the ventilation slot 41 and clogging the vents or contaminating the internal structure, ensuring the long-term stable operation of the heat dissipation system.

[0031] Working principle: Under normal use, the pin 32 is inserted into the groove 35 of the circular plate 34 under the elastic force of the spring 36, locking the circular plate 34 to the frame 31 and keeping the handlebar body 2 in the unfolded state to ensure the stability of the handlebar during riding. At this time, the spring 36 is in a compressed state, providing a continuous locking force. When the handlebar needs to be folded, pull the pull ring 33 to move the pin 32 outward, compressing the spring 36 and causing the pin 32 to disengage from the groove 35. At this time, the circular plate 34 can rotate around the inner wall of the frame 31. The ball bearings 37 on the inner wall of the frame 31 can reduce the friction of the circular plate 34 during rotation, making the adjustment process smoother. The handlebar body 2 is then folded to a position close to the handlebar 1, reducing the overall size of the bicycle for easy storage or transportation. The scale strip 38 on the surface of the circular plate 34 cooperates with the pointer 39 on the frame 31 to accurately position the handlebar angle. After adjustment, release the pull ring 33, the spring 36 returns to its original position, and pushes the pin 32 into the new groove 35 to complete the angle locking.

[0032] During riding, external air enters the air intake pipe 43 through the air collection pipe 44, and then flows into the ventilation groove 41 inside the handle body 2. When the air flows in the ventilation groove 41, it is then discharged through the round hole 42 on the arc surface of the handle, forming an air circulation, reducing the handle temperature and improving grip comfort. The filter plate 46 on the inner wall of the air collection pipe 44 can filter dust and impurities in the air, preventing foreign objects from entering the ventilation groove 41 and clogging the air holes or contaminating the internal structure, ensuring the long-term stable operation of the heat dissipation system. The rubber anti-slip strip 45 on the surface of the handle body 2 increases the grip friction without affecting the airflow of the ventilation groove 41 and the round hole 42, achieving a combination of anti-slip and heat dissipation functions.
