Description

Technical Field

[0001] This utility model relates to motorcycle or electric vehicle accessories, specifically motorcycle or electric vehicle speed control levers. Background Technology

[0002] Electric vehicles and motorcycles are commonly used means of transportation in people's lives. They have the advantages of being convenient and lightweight. A throttle typically includes a throttle core, a throttle head, and a grip cover. The throttle core includes a core tube and a head formed at one end of the core tube. The throttle head is fitted onto the head, and the grip cover is fitted onto the throttle core along the tail end of the core tube. The existing assembly method of the throttle head and throttle core is that a connector sleeve extends axially on the throttle head, and the end of the connector sleeve is provided with a hook. A snap-fit ​​groove is provided on the inner wall of the core tube of the throttle core. After the connector sleeve is inserted into the core tube, the hook and the snap-fit ​​groove engage, and the throttle head and throttle core are assembled completely. That is, the assembly point corresponds to the middle position of the core tube of the throttle core, as disclosed in CN220221032U (publication date: 2023-12-22) and CN 220786031 U (announcement date: 2024.04.16). In the existing structure, the outer dimensions of the throttle core are increased, which in turn requires a corresponding increase in the outer diameter of the grip leather. The increased grip leather reduces the comfort of holding the grip. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects of the existing technology and provide a reasonable motorcycle or electric vehicle speed control lever assembly structure. This structure avoids the influence of the assembly structure on the size of the throttle core, allowing for a more flexible size design of the throttle core, meeting the requirements of size reduction design, and thus improving grip comfort.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A motorcycle or electric vehicle throttle control assembly structure includes a throttle inner core and a throttle head. The throttle inner core includes a core tube and a head formed at one end of the core tube. The throttle head has a U-shaped cross-section and has an outer sleeve and an inner sleeve. The head has a seat ring, and the outer sleeve is fitted onto the seat ring. The throttle head is configured to be rotatably fitted onto the head and form an annular assembly cavity. The head further has an inner insert ring, the end of which is formed with uniformly circumferentially shaped... At least two buckles are distributed, with the buckle's snap-fit ​​joint protruding towards the outer periphery of the inner insert ring. The inner ring is configured for the inner insert ring to be inserted and corresponds to the annular assembly cavity. A stepped groove is provided at the axial end wall connection between the inner ring and the throttle head. The stepped groove communicates with the cylinder hole of the inner ring, so that after the inner insert ring is inserted along the cylinder hole of the inner ring, the buckle snaps into the stepped groove. The stepped groove has a guide stroke along the circumference for the buckles to slide relative to each other to accommodate the relative rotation of the throttle core and the throttle head.

[0006] By adopting the above technical solution, an inner insert ring is formed on the inner core of the throttle. The inner insert ring is inserted into the throttle head and fixed with a buckle. That is, the axial dimension of the inner ring on the throttle head is shortened, and the inner ring corresponds to the annular assembly cavity, rather than extending into the core tube of the throttle inner core. In other words, the assembly structure of the throttle head and the throttle inner core corresponds to the head position of the throttle inner core. The core tube of the throttle inner core has a more flexible size design, and the size can be reduced when needed. Similarly, the size of the grip leather fitted on the throttle inner core can also be reduced, thereby improving grip comfort.

[0007] This utility model also discloses a motorcycle or electric vehicle speed control lever, including a throttle inner core, a throttle head, and a grip leather. The throttle inner core includes a core tube and a head formed at one end of the core tube. The throttle head has a U-shaped cross-section and has an outer sleeve and an inner sleeve. The head has a seat ring, and the outer sleeve is fitted onto the seat ring. The throttle head is configured to be rotatably fitted onto the head and form an annular assembly cavity. A return torsion spring is provided in the annular assembly cavity. The grip leather is fitted onto the throttle inner core along the tail end of the core tube. The characteristic feature is that the head also has an inner sleeve. The inner insert ring has at least two snaps evenly distributed circumferentially at its end. The snaps protrude outwards from the outer periphery of the inner insert ring. The inner ring is configured to allow the inner insert ring to be inserted and corresponds to the annular assembly cavity. A stepped groove is provided at the axial end wall connection between the inner ring and the throttle head. The stepped groove communicates with the cylinder hole of the inner ring. Thus, after the inner insert ring is inserted along the cylinder hole of the inner ring, the snaps engage in the stepped groove. The stepped groove has a guide stroke circumferentially for the snaps to slide relative to each other to accommodate the relative rotation of the throttle core and the throttle head.

[0008] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

[0018] Example

[0019] See appendix Figures 1-2This utility model discloses an assembly structure for a motorcycle or electric vehicle speed control lever, including a throttle inner core 1 and a throttle head 2. The throttle inner core 1 has a core tube 11 and a head 12 located at one end of the core tube 11. The throttle head 2 is fitted onto the head 12 and forms an annular assembly cavity 10. The throttle head 2 has a U-shaped cross-section and has an outer sleeve and an inner sleeve 21. The head 12 has a seat ring, and the outer sleeve is fitted onto the seat ring. The throttle head 2 is configured to be rotatably fitted onto the head 12 and forming the annular assembly cavity 10. The throttle inner core 1 is configured to rotate relative to the throttle head 2 within a certain angle. The throttle is usually a speed control lever, and turning the throttle achieves riding speed control. A return torsion spring 5 is provided in the annular assembly cavity 10 to drive the throttle inner core 1 to rotate relative to the throttle head 2 to the initial position. One end of the return torsion spring 5 is hung on the throttle head 2, and the other end of the return torsion spring 5... When the inner core 1 of the throttle is rotated relative to the throttle head 2 and hung on the head 12, the return torsion spring 5 stores energy, and the grip leather is fitted onto the inner core 1 along the tail end of the core tube. The head 12 also has an inner insertion sleeve ring 124, and at least two buckles 1241 are formed at the end of the inner insertion sleeve ring 124, which are evenly distributed circumferentially. The buckle heads of the buckles 1241 protrude towards the outer periphery of the inner insertion sleeve ring 124. The inner sleeve 21 is configured for internal insertion. The inner ring 124 is inserted and corresponds to the annular assembly cavity 10. A stepped groove 22 is provided at the axial end wall connection between the inner ring 21 and the throttle head 2. The stepped groove 22 communicates with the cylinder hole of the inner ring 21. After the inner ring 124 is inserted along the cylinder hole of the inner ring, the buckle 1241 is engaged in the stepped groove 22. The stepped groove 22 has a guide stroke along the circumference for the buckle to slide relative to each other to adapt to the relative rotation of the inner core 1 and the throttle head 2. An inner insert ring is formed on the inner core of the throttle grip. This inner insert ring is inserted into the throttle head and secured with a clip. This means the axial dimension of the inner ring on the throttle head is shortened, and the inner ring aligns with the annular assembly cavity instead of extending into the core tube of the throttle grip. In other words, the assembly structure of the throttle head and the throttle grip core corresponds to the head position of the throttle grip core. The core tube of the throttle grip core has a more flexible size design, allowing for size reduction when needed. Similarly, the grip leather fitted onto the throttle grip core can also be reduced in size, thereby improving grip comfort. This design can be applied to ordinary adjustable throttle grips.

[0020] Example

[0021] The above assembly structure can also be applied to heated throttle grips. When applied to heated throttle grips, it not only improves grip comfort during riding, but also, due to the reduced size of the throttle core, decreases the area required for the heating element, resulting in a cumulative advantage in overall cost control. Furthermore, it allows for a better dimensional difference design between the core tube and the head of the throttle core, providing more space for the power cord hole. The following is a more detailed explanation of motorcycle or electric vehicle shift levers with reference to the accompanying drawings.

[0022] like Figures 3-9As shown, a motorcycle or electric vehicle speed control lever includes a throttle core 1, a throttle head 2, a grip leather 3, and a heating assembly 6. The throttle core 1 has a core tube 11 and a head 12 located at one end of the core tube 11. The throttle head 2 is fitted onto the head 12 and forms an annular assembly cavity 10. The throttle head 2 has a U-shaped cross-section and has an outer sleeve and an inner sleeve 21. The head 12 has a seat ring, and the outer sleeve is fitted onto the seat ring. The throttle head 2 is configured to be rotatably fitted onto the head 12 and forming the annular assembly cavity 10. The head 12 has a magnet support 121 located in the annular assembly cavity 10, and a magnet 4 is mounted on the magnet support 121. The throttle core 1 is configured to be rotatable relative to the throttle head 2 within a certain angle. The throttle is usually a speed control lever, and turning the throttle achieves riding speed control. A return torsion spring 5 is provided in the annular assembly cavity 10 to drive the throttle core 1 to rotate relative to the throttle head 2 to an initial position. One end of the spring 5 is hung on the throttle head 2, and the other end of the return torsion spring 5 is hung on the head 12. When the inner core 1 of the throttle is rotated relative to the throttle head 2, the return torsion spring 5 stores energy, and the grip leather is fitted onto the inner core 1 of the throttle along the tail end of the core tube. The head 12 also has an inner insert ring 124. The end of the inner insert ring 124 is formed with at least two buckles 1241 evenly distributed in the circumferential direction. The buckle heads of the buckles 1241 protrude towards the outer periphery of the inner insert ring 124. 21 is configured to allow the inner insert ring 124 to be inserted and corresponds to the annular assembly cavity 10. A stepped groove 22 is provided at the axial end wall connection between the inner ring 21 and the throttle head 2. The stepped groove 22 communicates with the cylinder hole of the inner ring 21. Thus, after the inner insert ring 124 is inserted along the cylinder hole of the inner ring, the buckle 1241 is engaged in the stepped groove 22. The stepped groove 22 has a guide stroke along the circumference for the buckle to slide relative to each other to accommodate the relative rotation of the throttle inner core 1 and the throttle head 2. The heating assembly 6 includes a heating element 61 and a power connection cable 62 connecting the heating element 61. After the heating element 61 is arranged around the core tube of the throttle inner core 1, the grip leather 3 is fitted on it. The head 12 has a power cable hole 122 along the axial direction for communicating with the outside of the core tube 11 and the annular assembly cavity 10. The power connection cable extends into the annular assembly cavity 10 through the power cable hole 122, and after being wound along the annular assembly cavity 10 to form a retractable coil 621, it passes through the axial end wall of the throttle head 2. Since one end of the power connection cable 62 is connected to the heating element 61, and the heating element 61 is covered and fixed to the throttle inner core 1, and the other end of the power connection cable 62 passes through the axial end wall of the throttle head 2, that is, it is fixed to the throttle head, the power connection cable is pulled when the throttle inner core rotates relative to the throttle head, and the diameter of the retractable coil changes accordingly, thus avoiding damage to the power connection cable.The power cable for the heating element on the throttle is passed through the axial end face of the throttle head. The inner end of the throttle on a motorcycle or electric vehicle usually corresponds to the handlebar switch. Therefore, the power cable passing through the axial direction of the throttle head can directly enter the handlebar switch, thus satisfying the requirement for a concealed arrangement of the power cable. This not only results in a neat and aesthetically pleasing appearance but also does not affect the safe operation of the throttle.

[0023] An isolation ring 7 is provided within the annular assembly cavity 10. The telescopic coil 621 and the return torsion spring 5 are located on opposite axial sides of the isolation ring 7. A clearance interval is provided on the outer periphery of the isolation ring 7 for the power connection cable 62 to pass through and ultimately exit via the axial end wall of the throttle head 2. This isolation ring isolates the telescopic coil and the return torsion spring, preventing the power connection cable from getting stuck in the return torsion spring. The wall 125 on the head 12 corresponding to the clearance interval is tapered. This allows the electrical connection cable to extend more smoothly through the clearance interval and ensures better positioning of the telescopic coil.

[0024] The isolation ring 7 is positioned and fitted onto the inner insert ring 124, and a relief notch 72 corresponding to the position of the buckle 1241 is provided on the inner circumference of the isolation ring 7. The isolation ring 7 is axially abutted and limited on the head by the inner insert ring 124. A ring support portion 211 is provided on the inner ring 21, and the inner edge of the isolation ring 7 is supported on the ring support portion 211. The ring support portion 211 is in the shape of a rib. Of course, the isolation ring 7 can also be fixed in other ways, such as directly snapping it onto the head, or fixing it with fasteners, etc. However, the above structure has the advantages of simple structure and convenient assembly.

[0025] To facilitate the installation and ensure the stability and reliability of the isolation ring 7 after installation, the outer circumferential side of the isolation ring 7 has a positioning protrusion 71, and the head 12 has an axially recessed positioning notch 123 on the outer circumferential wall corresponding to the annular assembly cavity 10. The positioning protrusion 71 is inserted into the positioning notch 123. There are two positioning notches and two positioning protrusions.

[0026] The heating element can be a heating wire wound around the inner core of the throttle, but this has drawbacks such as inconvenient processing and insufficient safety. Therefore, preferably, the heating element 61 is a flexible PCB board. The PCB board is wound and covered around the outer circumference of the core tube 11 of the inner core 1 of the throttle. To ensure reliable fixation of the PCB board, several rows of positioning holes 611 are distributed circumferentially on the PCB board. Each row of positioning holes 611 includes several positioning holes 611 distributed axially along the core tube. The outer circumference of the core tube 11 of the inner core 1 of the throttle has protruding positioning protrusions 111 that correspond one-to-one with the positioning holes 611. On the one hand, the positioning protrusions position and fix the flexible PCB board; on the other hand, the positioning protrusions support the grip leather, avoiding pressure on the flexible PCB board. Figure 3 The dimensions of the center grip leather are expressed in a free state, thus interference exists. However, after actual assembly, as shown in the attached figure... Figure 5The positioning protrusion shown extends out of the positioning hole 611. The grip leather 3 is sleeved on the core tube 11 of the inner core 1 of the throttle and supported by the positioning protrusion 111.
