These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0061] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0062] With the continuous development of science and technology, the types of people's means of transportation have gradually increased. In addition to traditional fuel vehicles, various electric vehicles with simple structures and easy driving have gradually entered people's lives. Electric vehicles are easy for drivers to learn and use. They have the advantages of labor saving, light weight, environmental protection, and low cost, and are deeply favored by the majority of users.

[0063] The handlebar mechanism of the present application can be applied to electric vehicles. For example, the electric vehicle can be an electric bicycle, an electric motorcycle or an electric scooter, which is not limited in the present application.

[0064] An electric vehicle generally includes a power source and a drive motor. The power source can provide electrical energy to the drive motor of the electric vehicle. The motor converts the electrical energy of the power source into mechanical energy to drive the wheels to move. Electric vehicles generally use a handlebar accelerator to control the speed of the vehicle. A handlebar accelerator is provided at the handlebar. The user can turn the handlebar accelerator to drive the handlebar accelerator to adjust the speed of the vehicle.

[0065] In the related art, the handlebar turning mechanism includes a base and a rotating component. When the handlebar turning mechanism is installed on the handlebar, the base and the rotating component need to be sequentially mounted on the handlebar and the base and the rotating component need to be matched and connected. Finally, the handlebar cover is mounted on the outer wall of the handlebar. However, the overall size of the handlebar is large, and it is difficult to sequentially mount and assemble the multiple parts of the base and the rotating component on the handlebar, which easily affects the assembly efficiency.

[0066] Based on the above technical problems, the applicant has improved the structure of the existing handlebar turning mechanism. In the embodiment of the present application, the base and the rotating component can be sleeved on the handlebar core, and the base, the rotating component and the handlebar core can be assembled into an integrated structure and then sleeved on the handlebar. Specifically, the staff can install the handlebar turning mechanism on the handlebar through the locking piece, thereby improving the installation efficiency of the handlebar turning mechanism and the handlebar.

[0067] The handlebar mechanism and the electric vehicle provided by the present application are described below with reference to the accompanying drawings and in combination with specific embodiments.

[0068] See also Figures 1 to 3 As shown, the handlebar mechanism 100 of the embodiment of the present application includes a half handlebar component, a base 120 and a rotating component 130 .

[0069] The half handlebar component includes a handlebar core 110. The handlebar core 110 can be configured to be connected to the handlebar. The handlebar core 110 is provided with a mounting portion 110a. The base 120 can be sleeved on the handlebar core 110 and located at the mounting portion 110a. The rotating component 130 can be sleeved on the handlebar core 110 and located at the mounting portion 110a. Along the axial direction X of the handlebar core 110, the rotating component 130 is arranged side by side with the base 120. The rotating component 130 is rotatably connected to the base 120 and the handlebar core 110.

[0070] The base 120 and the rotating component 130 of the embodiment of the present application can be sleeved on the outside of the handle core 110. The base 120 and the rotating component 130 can be assembled into an integrated structure through the handle core 110, and then assembled on the handlebar, so as to reduce the difficulty of assembling multiple parts in the base 120 and the rotating component 130 sequentially sleeved on the handlebar, which is conducive to improving the assembly efficiency of the staff.

[0071] In some possible implementations, see Figure 4 and Figure 5 As shown, the handlebar turning mechanism 100 of the embodiment of the present application may further include a clamping ring 140. The clamping ring 140 may be sleeved on the outside of the handlebar core 110, and the base 120 may be sleeved on the outside of the clamping ring 140 and connected to the clamping ring 140. The clamping ring 140 clamps the handlebar core 110 to the handlebar.

[0072] In the embodiment of the present application, the clamping ring 140 can provide a radial force for the handle core 110 to connect with the handlebar, so that the handle core 110 and the handlebar are clamped tightly. In addition, the clamping ring 140 and the base 120 are connected to each other, and the base 120 and the handle core 110 are also connected.

[0073] In some possible implementations, see Figure 6 and Figure 7 As shown, the end of the handle core 110 corresponding to the clamping ring 140 of the embodiment of the present application may be provided with a limiting opening 110c. The limiting opening 110c extends along the axial direction X of the handle core 110. Part of the inner wall of the clamping ring 140 is located in the limiting opening 110c, and part of the inner wall of the base 120 may also be located in the limiting opening 110c.

[0074] In some examples, the limiting opening 110c may penetrate the handle core 110 in the radial direction of the handle core 110. The limiting opening 110c may be used to improve the elasticity of the end of the handle core 110, so that when the clamping ring 140 is clamped, the end of the handle core 110 with the limiting opening 110c may be elastically deformed and pressed against the handlebar.

[0075] In some examples, the clamping ring 140 may have an elastic opening. Specifically, the clamping ring 140 has two ends. There is a gap between the two ends. When the clamping ring 140 applies a radial clamping force to the handle core 110, the gap between the two ends is reduced.

[0076] For example, adjustment holes may be provided on the two corresponding ends of the clamping ring 140. The base 120 may also be provided with corresponding adjustment holes. The locking screw 160 may be inserted through the adjustment holes of the base 120 and the adjustment holes on the two ends of the clamping ring 140. The locking screw 160 may have the function of connecting the base 120 and the clamping ring 140, and the distance between the two ends of the clamping ring 140 may also be adjusted by the locking screw 160 so that the clamping ring 140 can clamp the handlebar core 110 to the handlebar.

[0077] For some examples, see Figure 6 and Figure 7 As shown, part of the inner wall of the clamping ring 140 may be located in the limiting opening 110c. For example, the inner wall of the clamping ring 140 may be provided with a first protrusion 141. The first protrusion 141 may interact with the inner wall of the clamping ring 140 to reduce the possibility of relative rotation between the clamping ring 140 and the handle core 110.

[0078] Similarly, in some examples, a portion of the inner wall of the base 120 may also be located within the limiting opening 110c. For example, the inner wall of the base 120 may be provided with a second protrusion 123. The second protrusion 123 may interact with the inner wall of the clamping ring 140 to reduce the possibility of relative rotation between the base 120 and the handle core 110.

[0079] For some examples, see Figure 6 As shown, along the axial direction X of the handle core 110, the first convex portion 141 and the second convex portion 123 are arranged side by side and are located in the limiting opening 110c. The second convex portion 123 can also block the transition movement of the first convex portion 141 toward the direction of the steering handle 132, so as to facilitate the staff to match the adjustment hole on the clamping ring 140 with the adjustment hole on the base 120 during the installation process.

[0080] In some possible implementations, see Figure 6 As shown, the outer wall of the handle core 110 of the embodiment of the present application may be provided with a first buckle 111. The inner wall of the base 120 may be provided with a second buckle 121. Along the axial direction X of the handle core 110, the clamping ring 140 and the second buckle 121 may be located on both sides of the first buckle 111 respectively.

[0081] The locking screw 160 can provide radial locking force for the clamping ring 140 and the handle core 110, and can also provide connecting force for the base 120 and the clamping ring 140. The first buckle 111 and the second buckle 121 can constrain each other so that the handle core 110 and the base 120 are not easily separated from each other, thereby achieving a positioning connection between the base 120 and the handle core 110.

[0082] In some possible implementations, see Figure 7 As shown, the rotating component 130 of the embodiment of the present application may include a finger lever 131 and a steering handle 132. The finger lever 131 may be disposed on the outer wall of the steering handle 132.

[0083] The user can adjust the speed of the electric vehicle by turning the steering handle 132 , or by pressing a button on the finger lever 131 , to meet the needs of people with different habits.

[0084] See also Figure 8 As shown, along the axial direction X of the handle core 110, the steering handle 132 and the base 120 can be connected. The outer wall of the handle core 110 can be provided with a limiting protrusion 112. The limiting protrusion 112 can be located at the mounting portion 110a. The inner wall of the steering handle 132 can be provided with a limiting step 1321. Along the axial direction X of the handle core 110, the limiting protrusion 112 is matched and connected with the limiting step 1321. The limiting protrusion 112 is configured to constrain the steering handle 132 to move in a direction away from the mounting portion 110a.

[0085] In the embodiment of the present application, along the axial direction X of the handle core 110, the base 120 is connected to the steering handle 132. When the base 120, the clamping ring 140 and the handle core 110 are connected, the base 120 can prevent the steering handle 132 from slipping out. When the limiting step 1321 on the inner wall of the steering handle 132 cooperates with the limiting convex part 112 on the outer wall of the handle core 110, the limiting convex part 112 can prevent the steering handle 132 from moving away from the base 120, so that the steering handle 132 and the handle core 110 can be positioned and connected.

[0086] In some examples, the limiting protrusion 112 may extend along the circumference of the handle core 110 to form an annular protrusion structure. The surface of the limiting protrusion 112 facing the base 120 may be constrained by the limiting step 1321 .

[0087] In some possible implementations, see Figures 8 to 10 As shown, along the axial direction X of the handle core 110, the base 120 may have a first accommodating cavity 120a facing the steering handle 132. A first limiting portion 122 is provided in the first accommodating cavity 120a. The steering handle 132 may have a second accommodating cavity 132a facing the base 120. The base 120 and the steering handle 132 are docked, and the first accommodating cavity 120a and the second accommodating cavity 132a may be connected. A second limiting portion 1322 is provided in the second accommodating cavity 132a. Part of the base 120 may be located in the second accommodating cavity 132a. Part of the steering handle 132 may be located in the first accommodating cavity 120a. Along the circumferential direction of the handle core 110, the first limiting portion 122 is configured to constrain the rotation angle of the steering handle 132.

[0088] When the user turns the steering handle 132 to adjust the driving speed, the user needs to turn his wrist. Therefore, the turning angle of the steering handle 132 should not be set too large. When the user turns the steering handle 132, when the first limit portion 122 contacts the second limit portion 1322, the steering handle 132 reaches the maximum turning angle. At this time, the electric vehicle can accelerate to the maximum driving speed. By setting the maximum turning angle of the steering handle 132, the possibility of the user turning his wrist too much during the turning process to affect the operating comfort can be reduced.

[0089] In some examples, the rotation angle range of the steering handle 132 can meet ergonomics. For example, the rotation angle of the steering handle 132 can be less than or equal to 90 degrees.

[0090] In some possible implementations, see Fig. 9 As shown, the first limiting portion 122 may include a first limiting seat 1221 and a second limiting seat 1222. Along the circumference of the handle core 110, a rotation space 122a is defined between the first limiting seat 1221 and the second limiting seat 1222. Part of the second limiting portion 1322 is located in the rotation space 122a.

[0091] In the embodiment of the present application, part of the first limit seat 1221 and part of the second limit seat 1222 can extend out of the first accommodating cavity 120a and be located in the second accommodating cavity 132a. During the rotation of the steering handle 132, the second limit portion 1322 can rotate in the rotation space 122a formed by the first limit seat 1221 and the second limit seat 1222. For example, Fig. 9 The space between the two arrows may refer to the rotation space 122a.

[0092] Specifically, refer to Fig. 9 In the direction shown, the handlebar mechanism 100 in the embodiment of the present application can be applied to the right handle of the electric vehicle. The handlebar mechanism 100 can be inserted into the handlebar through one end close to the base 120. In the initial state of the steering handle 132, the second limit portion 1322 on the steering handle 132 can contact the first limit seat 1221 on the base 120. When the user needs to adjust the driving speed, the steering handle 132 can be turned clockwise. When the second limit portion 1322 on the steering handle 132 contacts the second limit seat 1222 on the base 120, the electric vehicle can have the maximum driving speed.

[0093] In some possible implementations, see Figure 8 and Fig. 9 As shown, the embodiment of the present application may further include a steering reset member 150. The steering reset member 150 may be located in the space formed by the first accommodating cavity 120a and the second accommodating cavity 132a. The steering reset member 150 has a first free end and a second free end. The first free end may be connected to the first limiting portion 122, and the second free end is connected to the turning handle.

[0094] When the user turns the steering handle 132, the user needs to overcome the force of the steering reset member 150, so that the steering handle 132 is not easily accidentally touched and the speed increases. The user needs to apply a certain rotational force to turn the steering handle 132. When the user needs to reduce the driving speed, the force applied to the steering handle 132 can be released. At this time, the steering handle 132 can be quickly reset under the action of the steering reset member 150, and the user does not need to apply the reset force, so as to improve the convenience of reducing the driving speed.

[0095] In some examples, the steering reset member 150 may be a torsion spring. When the user turns the steering handle 132, the user needs to overcome the force of the torsion spring on the steering reset member 150, and the torsion spring generates elastic deformation. When the user releases the steering handle 132, the steering reset member 150 may release elastic potential energy to reset the steering handle 132 to the initial state.

[0096] In some examples, the first position limiting portion 122 may be provided with a mounting hole 122b. For example, the mounting hole 122b may be provided on the second position limiting seat 1222. The first free end of the steering reset member 150 may be provided in the mounting hole 122b, and the second free end may be provided on the steering handle 132.

[0097] In some possible implementations, see Fig. 9 and Fig.10 As shown, the second limiting portion 1322 may include a first limiting wall 13221 and a second limiting wall 13222. The first limiting wall 13221 may be configured to be connected to the first limiting seat 1221. The second limiting wall 13222 may be configured to be connected to the second limiting seat 1222.

[0098] During the rotation of the steering handle 132, part of the second limiting portion 1322 can rotate in the rotation space 122a formed by the first limiting seat 1221 and the second limiting seat 1222. Along the circumference of the handle core 110, the first limiting wall 13221 and the second limiting wall 13222 can be located at two ends of the second limiting portion 1322. When the steering handle 132 is in the initial state, the first limiting wall 13221 can contact the first limiting seat 1221. When the steering handle 132 is rotated to the maximum movement angle, the second limiting wall 13222 can contact the second limiting seat 1222.

[0099] See also Fig.10 As shown, the first limiting wall 13221 and the second limiting wall 13222 can form a containing space 1322a. The turning handle mechanism 100 can also include a sensing component. The sensing component can be arranged in the containing space 1322a. A magnetic member 180 is arranged in the first containing cavity 120a of the base 120.

[0100] In some examples, the sensing component can be a Hall sensor or a rotary encoder, etc., which is not limited in this application. Taking the sensing component as a Hall sensor as an example, the Hall sensor is a magnetic field sensor made according to the Hall effect. When current passes through a conductor in a magnetic field, the magnetic field will exert a force on the electrons in the conductor that is perpendicular to the direction of electron movement, thereby generating a potential difference in two directions perpendicular to the conductor and the magnetic flux lines. The Hall voltage changes with the change of the magnetic field strength. The stronger the magnetic field strength, the higher the voltage, and the weaker the magnetic field strength, the lower the voltage. Therefore, the Hall voltage can reflect the distance between the Hall sensor and the magnet.

[0101] In the embodiment of the present application, the surfaces of the first limiting wall 13221 and the second limiting wall 13222 facing each other can be surrounded to form a receiving space 1322a for receiving the sensing component. The magnetic member 180 can be arranged in the first receiving cavity 120a and corresponds to the sensing component. When the rotating component 130 rotates relative to the base 120, the relative position of the magnet and the sensing component changes, so that the magnetic field strength at the sensing component changes, thereby outputting a corresponding signal to adjust the driving speed of the electric vehicle.

[0102] In some possible implementations, see Figure 2 and Figure 3 As shown, the rotating component 130 may further include a handlebar cover 133. The handlebar cover 133 may be sleeved on the outside of a portion of the steering handle 132. When the user turns the steering handle 132, the base of the palm may contact the handlebar cover 133 to improve the user's comfort. In addition, the handlebar cover 133 may also protect the steering handle 132 to alleviate external impact forces and reduce damage to the steering handle 132 caused by external forces.

[0103] For some examples, see Figure 3 As shown, a plurality of limiting ribs may be provided in the area of ​​the outer wall of the steering handle 132 corresponding to the handle cover 133. The plurality of limiting ribs may be distributed at intervals along the circumference of the handle core 110. The limiting ribs may be used to improve the structural strength of the steering handle 132. On the other hand, the limiting ribs may also increase the friction between the steering handle 132 and the handle cover 133, thereby reducing the possibility of relative rotation between the handle cover 133 and the steering handle 132.

[0104] In some possible implementations, see Figure 7 As shown, the handle core 110 may also be provided with a grip portion 110b. Along the axial direction X of the handle core 110, the grip portion 110b and the mounting portion 110a are arranged side by side. The outer wall of the grip portion 110b may be provided with a handle cover 170. When driving the electric vehicle, the user may hold the grip cover 170 of the grip portion 110b to maintain the balance of the electric vehicle.

[0105] For some examples, see Figure 7 and Figure 8 As shown, the outer wall of the handle core 110 may also be provided with an annular rib 113. Along the axial direction X of the handle core 110, the mounting portion 110a and the gripping portion 110b may be located on both sides of the annular rib 113. There may be a gap between the rotating component 130 and the annular rib 113 to prevent the rotating component 130 from rubbing against the annular rib 113 during rotation, thereby preventing the rotating component 130 from being reset and causing the electric vehicle to be unable to decelerate in time, thereby causing a safety hazard.

[0106] The embodiment of the present application also provides an electric vehicle, which may include a frame. The frame includes two handlebars. The handlebar turning mechanism 100 may be arranged on one of the handlebars. For example, the handlebar turning mechanism 100 may be arranged on the right handlebar.
