Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle handrail technology, specifically, it relates to a rear handrail bracket for electric bicycles. Background Technology

[0002] In the use of electric bicycles, the rear handrail bracket is one of the key components to ensure the safety of the rear passenger. With the popularization of electric bicycles, the different riding needs of different groups of people (especially adults and minors) have put forward higher requirements for the functionality and safety of the rear handrail bracket.

[0003] Currently, most electric bicycle rear handlebar supports on the market use a metal rod structure directly fixed to the rear of the electric bicycle. This type of traditional handlebar design has a single function, only providing passengers with basic grip points. When minors are riding on the back seat, because their hand development is not yet mature and their grip strength is relatively small, during the electric bicycle's operation (such as when encountering sudden braking, bumpy roads, etc.), relying solely on the traditional metal rod handlebar can easily lead to minors slipping their hands and losing their balance due to insufficient grip strength, making it difficult to effectively ensure their riding safety.

[0004] Meanwhile, traditional rear armrest supports lack functional adaptability design for different passenger groups, and cannot flexibly adjust the structural form according to the physiological characteristics and gripping needs of passengers (adults and minors), making it difficult to balance the user experience and safety in different scenarios. Therefore, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an electric bicycle rear handlebar bracket that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: an electric bicycle rear handlebar bracket, including a C-shaped bracket, on which multiple fixing ears are fixedly connected. The fixing ears are fixedly connected to the rear side of the electric bicycle seat by fixing bolts. It also includes: a mounting shell, symmetrically fixedly connected to both ends of the C-shaped bracket; a rotating disc, rotatably connected to the mounting shell via a rotating shaft; a handlebar, fixedly connected to the rotating disc; a baffle, fixedly connected to the end of the handlebar away from the rotating disc; grooves, symmetrically opened on both sides of the rotating disc; multiple openings circumferentially spaced on the mounting shell that cooperate with the grooves; a limiting protrusion, slidably connected within the groove; a tension spring, disposed in the groove, with both ends fixedly connected to the limiting protrusion and the inner wall of the groove, respectively; and a pulling component for pulling the limiting protrusion into the groove, installed on the rotating disc, handlebar, and baffle. When the limiting protrusion is not pulled by the pulling component, it extends out of the opening under the elastic force of the tension spring.

[0007] Furthermore, the pulling component includes a T-shaped pull rope. A channel is provided in the rotating disk between the two sets of grooves. The T-shaped pull rope is located in the channel and its end is fixedly connected to the limiting protrusion. A through groove is provided in the handle that communicates with the channel. The end of the T-shaped pull rope away from the limiting protrusion extends into the through groove and extends out from the groove opening on the side of the through groove near the baffle.

[0008] To facilitate the pulling of the T-shaped rope, a rope tube connected to the through groove is further fixedly connected to the baffle. One end of the T-shaped rope extends out of the through groove and into the rope tube, and a pull head is fixedly connected to the other end of the rope tube.

[0009] To facilitate smoother movement of the T-shaped pull rope and extend its service life, the diameter of the channel and groove is larger than the diameter of the T-shaped pull rope, and the connection between the channel and the groove is arc-shaped.

[0010] To further enhance grip comfort and fit, the handle has rounded chamfers on all four sides.

[0011] To further enhance comfort and safety during use, the handle is provided with ergonomically designed grip grooves.

[0012] To further enhance comfort, a sponge pad is fixedly connected to the baffle.

[0013] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention addresses the differences in hand grip strength among different passengers (adults and minors) by flexibly adjusting the grip state. When adults ride, the horizontal grip meets the normal gripping needs. For minors, due to their weak grip strength, the vertical adjustment of the grip and the cooperation of the baffle create a structure that is easier to grip and provides better limit protection, thus solving the problem of insufficient protection for minors by traditional single metal rod handrail supports.

[0014] When minors ride, the vertical handlebars and the baffle form a three-dimensional limiting structure. With arms resting on the baffle and hands gripping the end of the baffle, the contact area between the body and the handlebars and the limiting points are increased. During sudden braking or bumpy road conditions, this can effectively reduce body swaying and prevent falls, significantly improving the safety of minors riding.

[0015] The grip switching is achieved through the combination of a T-shaped pull rope, tension spring, limit protrusion and through-hole. Pulling the pull rope releases / locks the limit, and rotating the grip adjusts the state. It is simple and easy to understand, without the need for professional tools and complicated steps. Users (including guardians of minors) can easily complete the operation, which is convenient for daily use and frequent scene switching (such as different people taking turns riding in a family trip).

[0016] The rotating and limiting structure, consisting of the mounting shell, rotating disk, and rotating shaft, combined with the continuous elastic force provided by the tension spring, ensures that the handlebar remains stable in both horizontal and vertical positions. The limiting protrusion, after passing through the opening, effectively restricts the rotation of the handlebar, ensuring the stability of the handlebar structure during riding and preventing situations where wobbling or displacement affects safety and user experience.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0026] Example 1:

[0027] Reference Figures 1-5 A rear grab handle bracket for an electric bicycle includes a C-shaped bracket 1 with multiple fixing ears 101 fixedly connected to it. The fixing ears 101 are fixedly connected to the rear side of the electric bicycle seat by fixing bolts. The bracket also includes: a mounting shell 2 symmetrically fixedly connected to both ends of the C-shaped bracket 1; a rotating disc 202 rotatably connected to the mounting shell 2 via a rotating shaft 201; a handlebar 3 fixedly connected to the rotating disc 202; a baffle 4 fixedly connected to the end of the handlebar 3 away from the rotating disc 202; and grooves 5 symmetrically formed on the rotating disc 202. On both sides of the mounting shell 2, multiple openings 203 are equidistantly arranged in a circular pattern to cooperate with the groove 5; a limiting protrusion 502 is slidably connected in the groove 5; a tension spring 501 is set in the groove 5, and its two ends are fixedly connected to the limiting protrusion 502 and the inner wall of the groove 5 respectively; a pulling component for pulling the limiting protrusion 502 into the groove 5 is installed on the rotating disk 202, the handle 3 and the baffle 4. When the limiting protrusion 502 is not pulled by the pulling component, it will extend out of the opening 203 under the elastic force of the tension spring 501.

[0028] The pulling assembly includes a T-shaped pull rope 503. A channel is provided in the rotating disk 202 between the two sets of grooves 5. The T-shaped pull rope 503 is located in the channel and its end is fixedly connected to the limiting protrusion 502. A through groove 504 connected to the channel is provided in the handle 3. The end of the T-shaped pull rope 503 away from the limiting protrusion 502 extends into the through groove 504 and extends out from the slot on the side of the through groove 504 near the baffle 4.

[0029] When an adult is riding on the back of the electric bicycle, there is no need to adjust the position of the handlebars 3. The passenger can simply hold the handlebars 3 in the lowered position with their hands to maintain body balance during the ride and ride normally.

[0030] When a minor is riding on an electric bicycle, first place the minor steadily on the rear seat of the electric bicycle, ensuring their sitting posture is stable. Then, pull the T-shaped pull cord 503 located between the handlebar 3 and the baffle 4. After the cord is under tension, it will cause the limiting protrusion 502 in the groove 5 of the rotating disk 202 to overcome the elastic force of the tension spring 501 and move into the groove 5 until the limiting protrusion 502 is completely disengaged from the opening 203 on the mounting shell 2, releasing the limiting lock between the rotating disk 202 and the mounting shell 2, allowing the handlebar 3 to rotate around the pivot 201. Then, rotate the handlebar 3 upwards to lower it from a horizontal position. When the state changes to vertical, during the rotation, pay attention to the alignment of the groove 5 on the rotating disk 202 with the through-hole 203 of the mounting shell 2. When the groove 5 connects with the through-hole 203, the limiting protrusion 502 automatically moves towards the through-hole 203 and passes through the through-hole 203 under the elastic force of the tension spring 501, thus completing the limiting and fixing of the grip 3 in the vertical state. At this time, the grip 3 remains vertical. Subsequently, minors can place their arms on the baffle 4 and hold the end of the baffle 4 with their hands. By utilizing the vertical state of the grip 3 and the structure of the baffle 4, they can obtain more stable support and limitation, ensuring body stability during the riding process.

[0031] Upon reaching the destination, pull the T-shaped rope 503 again to retract the limiting protrusion 502 back into the groove 5, release the vertical limit of the handle 3, and rotate the handle 3 downward to return to the horizontal lowered state, so that minors can easily get off the back seat of the electric bicycle.

[0032] To address the differences in hand grip strength among different riders (adults and minors), the handle 3 can be flexibly adjusted. When adults ride, the horizontal handle 3 meets the normal gripping needs. For minors, who have weaker grip strength, the vertical adjustment of the handle 3, in conjunction with the baffle 4, creates a structure that is easier to grip and provides better limit protection, thus solving the problem of insufficient protection for minors by traditional single metal rod handrail supports.

[0033] When minors ride, the vertical handlebars 3 and the baffle 4 form a three-dimensional limiting structure. With arms resting on the baffle 4 and hands gripping the ends of the baffle 4, the contact area between the body and the handlebars and the limiting points are increased. During sudden braking or bumpy road conditions, this can effectively reduce body swaying and prevent falls, significantly improving the safety of minors riding.

[0034] The grip 3 can be quickly switched by using the pull rope 503, tension spring 501, limit protrusion 502 and through 203. Pulling the pull rope can release / lock the limit, and rotating the grip 3 to adjust the state is simple and easy to understand. No professional tools or complicated steps are required. Users (including guardians of minors) can easily complete the operation, which is convenient for daily use and frequent scene switching (such as different people taking turns riding in family trips).

[0035] The rotating and limiting structure, consisting of the mounting shell 2, rotating disk 202, and rotating shaft 201, along with the continuous elastic force provided by the tension spring 501, ensures that the handlebar 3 can be stably maintained in both horizontal and vertical states. After the limiting protrusion 502 passes through the through-hole 203, it effectively restricts the rotation of the handlebar 3, ensuring the stability of the handlebar structure during riding and preventing any swaying or displacement that could affect safety and user experience.

[0036] Example 2:

[0037] Reference Figures 1-5 An electric bicycle rear handlebar bracket is basically the same as in Embodiment 1, but with a further improvement: a rope tube 505 connected to a through groove 504 is fixedly connected to the baffle 4. One end of the T-shaped pull rope 503 extends out of the through groove 504 and into the rope tube 505, and a pull head 506 is fixedly connected to the other end of the rope tube 505. The rope tube 505 connected to the through groove 504 is provided on the baffle 4, and the extended end of the T-shaped pull rope 503 passes through the rope tube 505 and the pull head 506 is fixed at the end. The rope tube 505 can guide and limit the pull rope, preventing the pull rope from shaking or deviating during use, making the pull rope more regular. The pull head 506 increases the contact area for applying force, making it easier for users to exert force and grip the handle. Whether adults or minors, they can easily and conveniently pull the T-shaped pull rope 503, improving the operational experience and efficiency of adjusting the state of the handlebar 3, and making the limit switching of the handlebar 3 smoother.

[0038] The diameter of the channel and groove 504 is larger than the diameter of the T-shaped pull rope 503. The connection between the channel and the groove 5 is arc-shaped, providing ample space for the pull rope to move and avoiding problems such as jamming or excessive friction due to limited space. This ensures smooth pulling. The arc-shaped connection between the channel and the groove 5 also guides and protects the pull rope, guiding it to change direction smoothly and reducing bending stress. It also prevents sharp edges from wearing down the pull rope, extending its service life and making the pulling operation more stable and reliable, thus ensuring the long-term effective operation of the entire limit adjustment mechanism.

[0039] Example 3:

[0040] Reference Figures 1-5 An electric bicycle rear handlebar bracket is basically the same as in Embodiment 2, but with a further improvement: all four sides of the handlebar 3 are provided with arc-shaped chamfers 301. The arc-shaped chamfers 301 on the four sides of the handlebar 3 can effectively eliminate the sharpness of the corners and prevent the passenger's hand from being injured or scratched by the sharp corners when holding it. At the same time, the arc transition makes the surface of the handlebar 3 more in line with the curvature of the palm, improving the comfort and fit of the grip, allowing the rear passenger to hold the handlebar 3 more firmly during the ride, reducing hand fatigue, and further enhancing the safety and experience of use.

[0041] The handle 3 has an ergonomically designed groove 302 that precisely conforms to the natural curvature and finger distribution of the hand, increasing the contact area between the passenger's hand and the handle 3 and distributing the force more evenly. This effectively disperses the pressure during gripping, reducing hand soreness caused by prolonged gripping. The groove 302 also provides clear guidance for finger placement, improving grip stability and preventing the hand from slipping during bumps or sudden braking, further enhancing comfort and safety.

[0042] A sponge pad 401 is fixedly connected to the baffle 4. The sponge pad 401, which is fixedly connected to the baffle 4, can provide cushioning for minors to place their arms on it through its softness and elasticity, avoiding the pain caused by the arms directly contacting the hard baffle 4, and improving the comfort of riding. At the same time, the sponge pad 401 increases the friction between the hand and the baffle 4, which can reduce the possibility of the hand slipping when the minor holds the end of the baffle 4. Especially in bumpy road conditions, it can further enhance the stability of the grip, making the riding experience safer and more comfortable.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
