Description

Novel bicycle handle with heating function

Technical Field

The invention relates to the technical field of bicycles, in particular to a novel bicycle handle with a heating function.

Background

Nowadays, the living standard and the technological progress are increasingly developed, and people have more and more modes of transportation. Among them, bicycles used as a traditional industry have a history of over 100 years, and with the increasing concern of people on environmental protection, bicycles become popular transportation and fitness tools in all countries of the world again.

When the bicycle is used during riding, a human body is exposed in the surrounding environment and is greatly influenced by the environment, and particularly when the bicycle is used in winter, a large amount of heat can be taken away in a cold environment while the energy of the human body is consumed during riding, so that the human body is easily damaged or even a traffic accident is easily caused. For example, the hands of a human body are frostbitten and numb in a long-term cold environment, and the hands are organs for controlling the direction, and a traffic accident can be caused in a serious condition. Gloves among the prior art can carry out certain protection to human hand, but the gloves for the heating adopt the mode that reduces the heat and give off mostly, can not play the effect of heating, and its protecting effect is general, and the gloves that need carry alone can increase the degree of difficulty when controlling the bicycle direction, increases the dynamics of holding the handle, skids easily in sleet weather, and is very inconvenient.

In addition, can use the brake lever often in the bicycle is ridden, and the brake lever does not often have any protection device, and the handle temperature of holding relatively when receiving cold weather influence is lower, often needs four fingers to stretch out and the incurving pulls the brake lever when using the brake lever, can lead to the finger temperature to reduce at the above-mentioned in-process that the brake lever used, and the expansion of finger leads to the hand temperature to give off fast, influences health mechanism and the safety of riding.

Detailed Description

The construction and principles of the bicycle handlebar described herein will now be explained in detail with reference to specific embodiments thereof, so that one of ordinary skill in the art can fully understand and implement the same.

As shown in fig. 1 and 2, a novel bicycle handle with heating function comprises a heating device and a brake lever; the heating device is a sleeve 5 fixedly sleeved on the surface of the handle, the surface of the sleeve 5 is provided with an accommodating chamber 51, a graphene heating film 52 is fixedly arranged in the accommodating chamber 51, an electrode is arranged on the graphene heating film 52, and the electrode is fixedly connected with an external electric connector 53 through a lead; the brake handle comprises a stand column 3, an operating handle 1, a positioning rod 2 and a rebound device 4 (the rebound device 4 is a compression spring); the upright post 3 is fixedly connected above the inner side of the handle; the operating handle 1 is rotatably connected with the upright post 3 through the middle part, is crossed with the handle on a horizontal plane to form a certain angle, and is divided into a pressing part 11 at the inner side and a connecting part 12 at the outer side through the upright post 3; the pressing part 11 is fixedly connected with the inner side of the handle through a rebound device 4; the positioning rod 2 is L-shaped and consists of a cross rod 21 and a vertical rod 22, the middle part of the vertical rod 22 is fixedly connected with the outer end of the connecting part 12, the top end of the vertical rod 22 is fixedly connected with a bicycle braking steel rope, and the cross rod 21 is supported outside the handle through the end part; the brake steel rope is driven to brake by pressing the pressing part 11.

The heating device of the bicycle handle is used for warming the hands of a human body and is embodied as follows: when riding, a hand is held on the outer surface of the sleeve 5, power is supplied to the graphene heating film 52 through the electric connector 53, and the graphene heating film 52 generates heat and then emits the heat to the palm of the human body, so that a heating effect is achieved; the graphene heating film 52 is very practical when being ridden for a short distance because of its high temperature rise speed. In order to make the graphene heating film 52 more uniformly radiate heat to hands and achieve an ideal heating effect, the surface of the sleeve 5 is covered with a heat conduction adhesive tape 54; preferably, the electric connector 53 is a USB interface, so that the power supply of the graphene heating film 52 is not limited to a conventional power supply, and the portable charger can be used.

In addition, when the brake lever is used, the pressing part 11 is pressed down by a thumb, so that the connecting part 12 moves upwards under the action of the fulcrum of the upright post 3, the positioning rod 2 is driven to move upwards, and the vertical rod 22 pulls the steel rope to realize braking; the pressing part 11 is released, and the original state is restored by the elastic action of the resilient means 4, and the brake is released. From the above, the brake lever of the present invention has several improvements over the prior art: firstly, only the thumb is needed when the brake handle is operated, and compared with the traditional four-finger buckle brake handle, the brake handle greatly saves hand actions and reduces consumption; secondly, the brake handle is arranged on the inner side of the handle through a lever type to replace a traditional front brake handle, so that the handle structure is greatly simplified, and the hand stretching space is expanded; thirdly, on the basis of the second advantage, the brake lever at the inner side of the handle is not easy to scratch when a vehicle collides, and the safety is higher; fourthly, on the basis of the heating function, the thumb in cold weather presses the brake lever and compares the pull of the traditional four-finger buckle, the hand stretching distance is greatly reduced, the palm does not need to be unfolded, the palm heat loss is greatly reduced, and the heating effect of the heating device is more facilitated.

In order to meet the brake operation that the thumb presses the pressing part 11 to the maximum extent, the specific parameters of the brake lever are designed as follows: according to the angle of fingers holding the handle, the operating handle 1 and the outer side of the handle form an angle of 65-75 degrees on a horizontal plane, so that a thumb can press in a proper space; II, enabling the length ratio of the pressing part 11 to the connecting part 12 to be 2: 1-8: 1 so as to reduce the pressing force of a thumb under the lever principle; and III, the end part of the cross rod 21 is arranged into an arc shape matched with the shape of the handle, so that the supporting state of the positioning rod 2 is more stable.

The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any manner. Those skilled in the art can make many possible variations and modifications to the technical solution of the present invention using the methods disclosed above, or modify equivalent embodiments with equivalent variations, without departing from the technical principle and scope of the present invention.
