[0018] Figure 7This is a schematic diagram of the throttle inner core of this utility model. Detailed Implementation

[0019] See appendix Figures 1-7 This utility model discloses a heated throttle for motorcycles or electric vehicles, comprising a throttle inner core 1, a throttle head 2, a grip leather 3, and a heating assembly 6. The throttle head 2 is annular. 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 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 inner core 1 is configured to rotate relative to the throttle head 2 within a certain angle. The throttle is typically speed-adjustable, and turning the throttle controls the riding speed. 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 its initial position. One end of the reset torsion spring 5 is hung on the throttle head 2, and the other end of the reset torsion spring 5 is hung on the head 12. When the inner core 1 of the throttle is turned relative to the throttle head 2, the reset torsion spring 5 stores energy. The heating assembly includes a heating element 61 and a power connection line 62 connecting the heating element 61. After the heating element 61 is arranged on the outer periphery of the core tube of the inner core 1, the grip leather 3 is put on. The head 12 has a power line hole 122 along the axial direction for communicating with the outer side of the core tube 11 and the annular assembly cavity 10. One end of the power connection line is connected to the heating element, and the other end of the power connection line extends into the annular assembly cavity 10 through the power line hole 122. After a retractable coil 621 is formed by winding along the annular assembly cavity 10, 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, which is covered and fixed to the inner core 1 of the throttle, and the other end of the power connection cable 62 passes through the axial end wall of the throttle head 2 (i.e., it is fixed to the throttle head), when the inner core of the throttle rotates relative to the throttle head, the power connection cable is pulled, and the coil diameter of the retractable coil changes accordingly, thus avoiding damage to the power connection cable. The power connection cable of the heating component on the throttle is passed through the axial end face of the throttle head. Since the inner axial end of the throttle on a motorcycle or electric vehicle usually corresponds to the handlebar switch, the power connection 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 connection cable. This not only results in a neat and aesthetically pleasing appearance but also does not affect the safe operation of the throttle.

[0020] 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.

[0021] 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.

[0022] To facilitate the assembly of the throttle head and the head, an inner insert ring 124 extends axially from the head 12. The inner insert ring 124 has a buckle 1241 protruding radially outward at its head end. The isolation ring 7 is positioned and fitted onto the inner insert ring 124, and a clearance recess 72 corresponding to the buckle 1241 is provided on the inner circumference of the isolation ring 7. The throttle head 2 has an inner ring 21 that fits onto the inner insert ring 124. A buckle step 22 is recessed at the junction of the inner ring 21 and the axial end wall of the throttle head. After the inner insert ring 124 is inserted into the inner ring 21, the buckle 1241 engages with the stepped groove 22 and can rotate on the stepped groove. As a conventional technique in the art, a guide groove corresponding to the stepped groove is provided on the wall of the inner ring. When the throttle head is axially fitted onto the head, the buckle engages with the stepped groove for fixation, offering the advantages of simple and convenient assembly. To ensure a simpler and more reliable fixation of the isolation ring, the isolation ring 7 is axially abutted and limited 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 rib-shaped. 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.

[0023] 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 5 The 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.
