Description

Technical Field

[0001] This utility model belongs to the field of electric bicycle technology, specifically relating to a throttle protection structure. Background Technology

[0002] In the field of electric bicycles (electric bicycles, electric motorcycles, electric scooters, etc.), the throttle is a component used to control the speed of the vehicle. It is usually installed on the right end of the handlebars. By rotating the throttle, the user changes the signal output by the controller to the motor, thereby adjusting the speed of the motor and realizing the acceleration or deceleration of the vehicle.

[0003] During the use of electric bicycles, tipping over is inevitable. Because the throttle is located at the outermost end in both left and right directions, it becomes the part directly impacted, causing cosmetic damage. In severe cases, it can even cause the throttle to jam, ultimately leading to accidents such as the vehicle running on its own (due to failure to spring back) or flying off the road. This situation is even more common and severe on shared bicycles.

[0004] To address this, some electric bicycles have added anti-collision components to the handlebars. These components have a certain lateral gap with the handlebars, allowing them to directly absorb impacts (contacting the ground) and preventing the throttle from being directly impacted. Although the throttle is secured to the handlebars with retaining rings and screws, it can still shift relative to the handlebars when the vehicle rolls over, especially with significant impacts and / or multiple occurrences. Furthermore, when the throttle shifts away from the anti-collision component instead of towards it during a rollover, the gap between the throttle and the handlebars increases, affecting aesthetics and user experience. Summary of the Invention

[0005] This invention addresses the shortcomings of existing electric bicycles where the anti-collision throttle gets stuck or the gap increases after a rollover. It provides a throttle protection structure to prevent the throttle from getting stuck and to avoid increasing the gap between the throttle and the anti-collision components.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a throttle protection structure, the throttle protection structure comprising:

[0007] Put the horizontal tube;

[0008] Brake lever assembly, fixed to the handlebar tube;

[0009] The car body, which secures the horizontal tubes;

[0010] The throttle assembly is mounted on the handlebar.

[0011] The anti-collision component is fixed on the handlebar tube, located at the outer end of the throttle assembly, and has a gap between it and the throttle assembly along the axial direction of the handlebar tube.

[0012] The brake lever assembly and / or the vehicle body form a first limiting part, and the vehicle body forms a second limiting part. The first limiting part limits the throttle assembly in a first direction along the handlebar tube axis, and the second limiting part limits the throttle assembly in a second direction along the handlebar tube axis.

[0013] The throttle protection structure of this utility model includes an anti-collision component located at the outer end of the throttle assembly. There is a gap between the anti-collision component and the throttle assembly along the axial direction of the handlebar tube. Thus, when the side of the vehicle where the throttle assembly is located is overturned, the anti-collision component touches the ground and absorbs the impact, while the throttle assembly does not bear the direct impact and will not be damaged. The first limiting part of the brake lever assembly limits the throttle assembly in a first direction (axially inward) along the axial direction of the handlebar tube, and the second limiting part of the vehicle body limits the throttle assembly in a second direction (axially outward) along the axial direction of the handlebar tube. Thus, the position of the throttle assembly on the handlebar tube is basically fixed, the throttle assembly will not displace toward the brake lever assembly, the gap between the throttle assembly and the anti-collision component will not increase, the displacement of the throttle assembly toward the anti-collision component is also limited, the throttle assembly will not abut against the anti-collision component, and the throttle assembly will not get stuck.

[0014] As an improvement, the throttle assembly forms a limiting groove, the limiting groove having a sidewall located between the second limiting portion and the brake lever assembly, the sidewall forming the second limiting portion.

[0015] As an improvement, the throttle assembly includes a retaining ring that is fixed to the handlebar tube by a fastening screw, a throttle seat that is sleeved outside the retaining ring and connected to the retaining ring to prevent rotation, the throttle seat having the limiting groove formed thereon, and the fastening screw fixing the retaining ring and the throttle seat together.

[0016] As an improvement, the throttle assembly also includes a rotating assembly, which includes a hard inner liner, a soft grip, and a limiting member fitted outside the throttle seat. The hard inner liner has a limiting hole, and the limiting member is inserted into the limiting hole. The end of the throttle seat facing the anti-collision assembly forms a third limiting part. The third limiting part limits the limiting member in a second direction along the handlebar tube axis, and the throttle seat limits the hard inner liner in a first direction along the handlebar tube axis.

[0017] As an improvement, the throttle assembly and brake lever assembly are made to contact each other along the handlebar axis.

[0018] As an improvement, an anti-rotation hole is provided in the handlebar, and the brake lever assembly also includes an anti-rotation element that passes through the anti-rotation hole in the handlebar.

[0019] As an improvement, the anti-rotation component is an anti-rotation screw, and the brake lever assembly includes a brake lever seat, with the anti-rotation screw threadedly connected to the brake lever seat; the brake lever seat includes a first clamping seat and a second clamping seat connected by a clamping screw.

[0020] As an improvement, the brake lever assembly forms an anti-rotation groove, and the throttle assembly forms an anti-rotation part, with the anti-rotation part located in the anti-rotation groove.

[0021] As an improvement, the anti-collision assembly includes an anti-collision cover fitted over the handlebar and a tensioning assembly located inside the handlebar, with a gap between the anti-collision cover and the throttle assembly along the axial direction of the handlebar.

[0022] As an improvement, the anti-collision assembly also includes an anti-collision block located between the anti-collision cover and the handlebar cross tube, the anti-collision block abutting against the end wall of the handlebar cross tube;

[0023] The tensioning assembly includes a tensioning block, a nut located at the inner end of the tensioning block and connected to the tensioning block to prevent rotation, and a tensioning screw. The tensioning screw passes through the anti-collision cover and the tensioning block from the outer end and is screwed into the nut. The tensioning block is squeezed by the nut to increase its outer diameter and then presses against the inner wall of the handlebar tube.

[0024] The beneficial effects of the throttle protection structure of this utility model are as follows: when the side of the vehicle where the throttle assembly is located overturns, the anti-collision component is grounded and bears the impact, while the throttle assembly does not bear the direct impact and will not be damaged; the first limiting part of the brake lever assembly limits the throttle assembly in the first direction (axially inward) along the handlebar tube axis, and the second limiting part of the vehicle shell limits the throttle assembly in the second direction (axially outward) along the handlebar tube axis, so that the position of the throttle assembly on the handlebar tube is basically fixed, the throttle assembly will not displace toward the brake lever assembly, the gap between the throttle assembly and the anti-collision component will not increase, the displacement of the throttle assembly toward the anti-collision component is also limited, the throttle assembly will not abut against the anti-collision component, and the throttle assembly will not get stuck.

[0039] G. Gap. Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be explained and described below. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0041] See Figures 1 to 9 The throttle protection structure of this utility model embodiment includes:

[0042] Put the horizontal tube;

[0043] Brake lever assembly, fixed to the handlebar tube;

[0044] The car body, which secures the horizontal tubes;

[0045] The throttle assembly is mounted on the handlebar.

[0046] The anti-collision component is fixed on the handlebar tube, located at the outer end of the throttle assembly, and has a gap between it and the throttle assembly along the axial direction of the handlebar tube.

[0047] The brake lever assembly and / or the vehicle body form a first limiting part, and the vehicle body forms a second limiting part. The first limiting part limits the throttle assembly in a first direction along the handlebar tube axis, and the second limiting part limits the throttle assembly in a second direction along the handlebar tube axis.

[0048] The throttle protection structure of this utility model includes an anti-collision component located at the outer end of the throttle assembly. There is a gap between the anti-collision component and the throttle assembly along the axial direction of the handlebar tube. Thus, when the side of the vehicle where the throttle assembly is located is overturned, the anti-collision component touches the ground and absorbs the impact, while the throttle assembly does not bear the direct impact and will not be damaged. The first limiting part of the brake lever assembly limits the throttle assembly in a first direction (axially inward) along the axial direction of the handlebar tube, and the second limiting part of the vehicle body limits the throttle assembly in a second direction (axially outward) along the axial direction of the handlebar tube. Thus, the position of the throttle assembly on the handlebar tube is basically fixed, the throttle assembly will not displace toward the brake lever assembly, the gap between the throttle assembly and the anti-collision component will not increase, the displacement of the throttle assembly toward the anti-collision component is also limited, the throttle assembly will not abut against the anti-collision component, and the throttle assembly will not get stuck.

[0049] Example 1

[0050] See Figures 1 to 9 The throttle protection structure of Embodiment 1 of this utility model includes:

[0051] Put the horizontal tube 1;

[0052] Brake lever assembly 2 is fixed on handlebar tube 1;

[0053] Car body 3, which fixes the horizontal tube 1 to the opposite side;

[0054] Thrust assembly 4 is installed on handlebar tube 1;

[0055] The anti-collision component 5 is fixed on the handlebar tube 1, located at the outer end of the throttle assembly 4, and has a gap G between it and the throttle assembly 4 along the axial direction of the handlebar tube 1.

[0056] The brake lever assembly 2 forms a first limiting part, and the vehicle body 3 forms a second limiting part 311. The first limiting part limits the throttle assembly 4 in a first direction along the axial direction of the handlebar tube 1, and the second limiting part 311 limits the throttle assembly 4 in a second direction along the axial direction of the handlebar tube 1.

[0057] In this embodiment, the throttle assembly 4 forms a limiting groove 421, the limiting groove 421 has a sidewall located between the second limiting part 311 and the brake lever assembly 2, and the sidewall forms the second limiting part 311.

[0058] In this embodiment, the body shell 3 includes a first shell 31 and a second shell 32, which are fixed together by screws. The second limiting portion 311 is formed on the first shell 31. The size of the limiting groove 421 along the axial direction of the handlebar tube 1 is larger than that of the second limiting portion 311 to accommodate machining and assembly errors. This allows the throttle assembly 4 to experience slight displacement along the axial direction of the handlebar tube 1, but this displacement is very small, at least less than the gap G between the throttle assembly 4 and the anti-collision assembly 5.

[0059] In this embodiment, the throttle assembly 4 includes a fixing ring 41 that is fixed to the handlebar tube 1 by a fastening screw 43, and a throttle seat 42 that is sleeved on the fixing ring 41 and connected to the fixing ring 41 to prevent rotation. The limiting groove 421 is formed on the throttle seat 42, and the fastening screw 43 fixes the fixing ring 41 and the throttle seat 42 together.

[0060] In this embodiment, the throttle assembly 4 further includes a rotating assembly, which includes a hard inner liner 45, a soft grip 46, and a limiting member 44 sleeved outside the throttle seat 42. The hard inner liner 45 has a limiting hole, and the limiting member 44 is inserted into the limiting hole. The end of the throttle seat 42 facing the anti-collision assembly 5 forms a third limiting part. The third limiting part limits the limiting member 44 in the second direction along the axial direction of the handlebar tube 1, and the throttle seat 42 limits the hard inner liner 45 in the first direction along the axial direction of the handlebar tube 1.

[0061] In this embodiment, the throttle seat 42 has multiple deformation grooves at the end facing the anti-collision component 5, allowing the limiting member 44 to be fitted onto the throttle seat 42 and held in place. The limiting member 44 is annular and extends radially to form multiple protrusions, which are inserted into the inner hard rubber liner 45. The limiting member 44, the inner hard rubber liner 45 (on which a magnet is also mounted), and the grip soft rubber 46 rotate relative to the throttle seat 42 as a whole. A Hall element is mounted on the throttle seat 42.

[0062] In this embodiment, the throttle assembly 4 and the brake lever assembly 2 are in contact along the axial direction of the handlebar tube 1. Specifically, the end face of the throttle seat 42 of the throttle assembly 4 is in contact with the end of the brake lever assembly 2.

[0063] In this embodiment, an anti-rotation hole 11 is provided in the cross tube 1, and the brake lever assembly 2 also includes an anti-rotation component that passes through the anti-rotation hole 11 in the cross tube 1, thereby ensuring that the brake lever assembly 2 will not rotate relative to the cross tube 1.

[0064] In this embodiment, the anti-rotation component is an anti-rotation screw, and the brake lever assembly 2 includes a brake lever seat, with the anti-rotation screw threadedly connected to the brake lever seat; the brake lever seat includes a first clamping seat and a second clamping seat connected by a clamping screw.

[0065] In this embodiment, the brake lever assembly 2 forms an anti-rotation groove 21, and the throttle assembly 4 forms an anti-rotation portion 471. The anti-rotation portion 471 is located in the anti-rotation groove 21, thereby ensuring the throttle seat 42. The throttle assembly 4 includes a cover 47, which encloses the Hall element in the mounting cavity of the throttle seat 42, and the anti-rotation portion 471 is formed on the cover 47.

[0066] In this embodiment, the anti-collision component 5 includes an anti-collision cover 51 fitted over the handlebar tube 1 and a tensioning component located in the handlebar tube 1. The anti-collision cover 51 and the throttle assembly 4 have a gap G along the axial direction of the handlebar tube 1.

[0067] In this embodiment, the anti-collision assembly 5 further includes an anti-collision block 52 located between the anti-collision cover 51 and the handlebar tube 1, with the anti-collision block 52 abutting against the end wall of the handlebar tube 1. The anti-collision block 52 is made of metal, and the anti-collision cover 51 is made of hard plastic, making the anti-collision assembly 5 and the throttle assembly 4 have basically the same appearance and texture.

[0068] In this embodiment, the tensioning assembly includes a tensioning block 53, a nut 54 located at the inner end of the tensioning block 53 and connected to it with an anti-rotation connection, and a tensioning screw 55. The tensioning screw 55 passes through the anti-collision cover 51 and the tensioning block 53 from its outer end and is screwed into the nut 54. The tensioning block 53 is compressed by the nut 54, causing its outer diameter to increase and press against the inner wall of the handlebar tube 1. The nut 54 has an anti-rotation protrusion. Before installing the anti-collision assembly 5 onto the handlebar tube 1, the anti-collision assembly 5 is pre-assembled so that the nut 54 compresses the tensioning block 53 to a certain extent (still smaller than the aperture of the handlebar tube 1). Then, the anti-collision assembly 5 is inserted into the handlebar tube 1, the anti-collision cover 51 is held down, and the tensioning screw 55 is turned. Since the nut 54, tensioning block 53, anti-collision block 52, and anti-collision cover 51 cannot rotate, the nut 54 will continue to compress the tensioning block 53, thus tightening the tensioning block 53 and the handlebar tube 1.

[0069] The beneficial effects of the throttle protection structure in Embodiment 1 of this utility model are as follows: when the side of the vehicle where the throttle assembly 4 is located overturns, the anti-collision component 5 is grounded and bears the impact, the throttle assembly 4 does not bear the direct impact, and the throttle assembly 4 will not be damaged; the first limiting part of the brake lever assembly 2 limits the throttle assembly 4 in the first direction (axial inward) along the handlebar tube 1, and the second limiting part 311 of the vehicle body 3 limits the throttle assembly 4 in the second direction (axial outward) along the handlebar tube 1, so that the position of the throttle assembly 4 on the handlebar tube 1 is basically fixed, the throttle assembly 4 will not displace toward the brake lever assembly 2, the gap G between the throttle assembly 4 and the anti-collision component 5 will not increase, the displacement of the throttle assembly 4 toward the anti-collision component 5 is also limited, the throttle assembly 4 will not abut against the anti-collision component 5, and the throttle assembly 4 will not get stuck.

[0070] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the content described in the above specific embodiments. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
