Description

Technical Field

[0001] This utility model relates to electric vehicles, specifically to a handlebar assembly for an electric vehicle. Background Technology

[0002] The handlebar assembly of an electric bicycle is primarily responsible for throttle control. Its core principle involves using Hall effect sensors to detect the handlebar's rotation within a predetermined angle, thereby adjusting the power output. The automatic return function after the handlebar has rotated is provided by a torsion spring. Over time, the torsion spring may gradually lose its elasticity due to metal fatigue, or even become damaged, ultimately causing the entire handlebar assembly to malfunction.

[0003] Referring to Chinese Patent Publication No. CN118289126A, Publication Date 2024-07-05, a handlebar, handlebar assembly, and electric vehicle are disclosed. The handlebar includes a first housing, a second housing, a swivel grip, a torsion spring, and a sensing magnet. The first housing and the second housing are detachably fitted together, forming a clamping mounting hole between them. The swivel grip is rotatably mounted on the clamping mounting hole. The torsion spring is located within the clamping mounting hole, with one end of the torsion spring directly or indirectly abutting against the first housing or the second housing, and the other end directly or indirectly abutting against the swivel grip. The sensing magnet is directly or indirectly disposed on the swivel grip. The handlebar also includes a Hall effect sensor. The first housing has a slot, and the Hall effect sensor is inserted into the slot, which is located outside the clamping mounting hole. The Hall effect sensor is screwed into the first housing. This application also discloses a handlebar assembly using the above-described handlebar and an electric vehicle.

[0004] How to replace the torsion spring as the reset element after the handlebars rotate, in order to extend the service life of the entire handlebar assembly, is a question we look forward to being answered! Utility Model Content

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1-5 As shown, a handlebar assembly for an electric vehicle includes a lower compartment 1 and a handlebar 2. The end of the handlebar 2 is fixedly provided with a rotating part 21 that is rotatably assembled in an annular groove 11 opened in the lower compartment 1. The rotating part 21 has a waist groove 22 on its opposite two end faces, and also includes a first shaft 12 located in the waist groove 22, one end of which is fixed to the inner wall of the ring groove 11, and the other end of which is fixed to the inner wall of the waist groove 22.

[0020] Specifically, the embodiment also includes an upper cabin 5, which is fixedly installed to the lower cabin 1 with screws, i.e. Figure 1 As shown, the internal structures of the upper cabin 5 and the lower cabin 1 are generally the same. The only difference is that a platform 51 is fixedly installed in the annular groove 11 of the upper cabin 5, and this platform is used to lead out the Hall sensor 6.

[0021] Furthermore, the Hall sensor 6 is fixedly installed in the annular groove 11 of the upper cabin 5 and maintains a predetermined distance from the platform 51. When the handle 2 is rotated to the termination angle, which is when the Hall sensor 6 has the maximum output power, the platform 51 will block the rotating part 21 of the handle 2.

[0022] More specifically, the circular rubber column 7 is provided with an arc-shaped strong magnet 8. The circular rubber column 7 is fixed in the circular hole opened on the rotating part 21. The arc-shaped strong magnet 8 is distributed on the inner wall of the recessed groove 23 opened on the side wall of the rotating part 21, and the outer wall of the arc-shaped strong magnet 8 is in contact with the detection end of the Hall sensor 6.

[0023] It should be noted that the aforementioned electronic components and control programs are common technical knowledge to those skilled in the art, and therefore will not be described in detail.

[0024] In the above technology, the elastic metal plate 3 is used to replace the torsion spring. There are no relative friction or hinged parts during use, which avoids the problem of metal fatigue fracture caused by repeated torsion like the torsion spring. The overall life is longer and the performance is more stable.

[0025] As a further embodiment of the present invention, the above-mentioned elastic metal plate 3 includes at least a V-shaped plate 31, the included angle of which changes as the rotating part 21 rotates.

[0026] Specifically, in the embodiment, when the handle 2 is rotated, the arc-shaped strong magnet 8 moves on the Hall sensor 6, thereby gradually increasing the output power of the Hall sensor 6. As the handle 2 rotates, the angle of the V-shaped plate 31 changes as the rotating part 21 rotates.

[0027] As another embodiment of the present invention, the elastic metal plate 3 includes a first arc-shaped portion 32, and an arc-shaped clamp 321 fixedly mounted on the first shaft 12 is provided at the end of the first arc-shaped portion 32.

[0028] Specifically, the first arc-shaped part 32 and the V-shaped plate 31 are manufactured using an integral molding process, ensuring the continuity of the structure and the integrity of the mechanical properties. When the user drives the handle 2 to rotate, the rotating part 21 causes the first arc-shaped part 32 to undergo elastic deformation, which in turn pulls the V-shaped plate 31 through its overall structure, causing the included angle of the V-shaped plate 31 to change accordingly.

[0029] This design not only enables smooth force transmission during rotation, but also significantly improves overall rigidity and fatigue life by reducing assembly nodes, avoiding the loosening and wear problems commonly found in multi-component hinges.

[0030] As a further embodiment of this utility model, the elastic metal plate 3 includes a second arc-shaped portion 33, one end of which is connected to the other end of the first arc-shaped portion 32, and the joint between the two is a U-shaped portion 43. A second shaft 13 located within the U-shaped portion 43 is fixedly disposed in the annular groove 11. The other end of the second arc-shaped portion 33 is integrally connected to the V-shaped plate 31, and the joint between the two is also a U-shaped portion 43.

[0031] Specifically, in this embodiment, the first arc-shaped portion 32 and the V-shaped plate 31 are connected as one unit by the second arc-shaped portion 33. A U-shaped portion 43 is provided at the junction of the second arc-shaped portion 33 and the first arc-shaped portion 32. The U-shaped portion 43 is inserted and engaged with the second shaft 13 to form a rotation fulcrum. When the handle 2 rotates, the first arc-shaped portion 32 is pulled and causes the second arc-shaped portion 33 to move.

[0032] As the second arc-shaped part 33 moves, the position of the U-shaped part 43 at its connection with the first arc-shaped part 32 also changes accordingly. Since the side wall of the end of the second arc-shaped part 33 connected to the V-shaped plate 31 is embedded in the limiting slide plate provided in the annular groove 11, during the rotation of the handle 2, the pulling force of the first arc-shaped part 32 on the second arc-shaped part 33 is converted into a linear traction force on the V-shaped plate 31 under the guidance and constraint of the limiting slide plate, thereby precisely controlling the V-shaped plate 31 to rotate with the rotating part 21 and change its included angle.

[0033] It should be noted that the aforementioned elastic metal plate 3 is a high-strength thin steel component.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
