[0043] According to some embodiments of the present application, the electric vehicle heated throttle further includes a replaceable Hall seat, which is fixedly connected to the end of the throttle housing 3 that is away from the end cover 2 by screws, and the other end of the magnetic steel seat 4 is located between the throttle housing 3 and the replaceable Hall seat, and the three form a second cavity.

[0044] According to some embodiments of the present application, the heated handlebar of the electric vehicle further includes a magnet 41 and a torsion spring 7, the magnet 41 is arranged on the magnet seat 4, and the magnet 41 is located in the second cavity, the torsion spring 7 is arranged in the second cavity, and one end of the torsion spring 7 is clamped and fixed to the magnet seat 4, and the other end is clamped and fixed to the replaceable Hall seat.

[0045] Specifically, a magnetic steel installation groove and a torsion spring hole are provided on the magnetic steel seat 4. The magnetic steel installation groove is used to install the magnetic steel 41, and the torsion spring hole is used to insert one end of the torsion spring 7 to form a clamping connection, so that the end of the torsion spring 7 can rotate with the magnetic steel seat 4.

[0046] By setting the magnet 41, the magnet 41 rotates synchronously with the magnet seat 4 when the handle is rotated, and cooperates with the Hall sensor to achieve the speed regulation effect of the vehicle; by setting the torsion spring 7, the torsion spring 7 will be twisted synchronously when the handle is rotated, and after the turning force of the handle disappears, the elastic restoring force of the torsion spring 7 can drive the handle to quickly return to the initial state.

[0047] According to some embodiments of the present application, the replaceable Hall seat includes a type A Hall seat 51 and a type B Hall seat 52, the type A Hall seat 51 is provided with a mounting boss 511 adapted to the integrated switch and a slot 512 adapted to the integrated switch Hall sensor, and the type B Hall seat 52 is provided with a locking aluminum ring 521, a locking screw 522 and a Hall sensor 523.

[0048] The A-type Hall seat 51 does not have a Hall sensor. When in use, it is only necessary to insert the existing integrated switch Hall sensor into the card slot 512, and then fix the heating handlebar inside the integrated switch. The B-type Hall seat 52 has a Hall sensor and can be used alone on vehicles without an integrated switch, such as electric tricycles and some electric motorcycles. In this way, the technical defects of the existing heated handlebars on the market, such as occupying a large space and not being able to borrow the original vehicle Hall sensor, are solved, and the technical defects of not being able to match the existing integrated switch are solved, which is economical and beautiful.

[0049] According to some embodiments of the present application, the A-type Hall seat 51 and the B-type Hall seat 52 are both provided with a clip 53 and a bolt hole 54, the clip 53 is used to form a clip connection with the slot 31 on the throttle housing 3, and there are multiple bolt holes 54 for forming a bolt connection with multiple bolt columns 32 on the throttle housing 3.

[0050] Specifically, the buckle 53 on the replaceable Hall seat is arranged on the circumferential edge of the replaceable Hall seat, and the card slot 31 on the throttle housing 3 is correspondingly arranged on the circumferential edge of the throttle housing 3. There are four bolt holes 54 on the replaceable Hall seat and four bolt columns 32 on the throttle housing 3, and the bolt holes 54 and the bolt columns 32 are arranged at corresponding positions on the circumference, so that the replaceable Hall seat and the throttle housing 3 are fixedly connected together by screws.

[0051] According to some embodiments of the present application, the electric vehicle heating handlebar further comprises a handlebar outer skin 8, which is formed on the outside of the winding tube 1 and one side of the end cap 2 by injection molding. The end of the winding tube 1 is provided with four mounting grooves 12 adapted to the side of the end cap 2 and a welding groove 13, wherein the four mounting grooves 12 are provided with screw holes adapted to the hole positions on the end cap 2, so that the end cap 2 is fixed to the end of the winding tube 1 by screws, and the welding groove 13 is provided with two small holes for the end of the heating wire 11 to pass through.

[0052] After the heating wire 11 is wound and fixed on the winding tube 1, the power cord 6 extends into the welding groove 13 through the threading hole 24 on the end cover 2, and the two ends of the heating wire 11 pass through the two small holes and are welded to the positive and negative electrodes of the power cord 6 in the welding groove 13. Since the power cord 6 directly supplies power to the heating wire 11, the power loss of the existing heating handle powered by springs or contact sheets in the market is solved, which is more energy-saving and safer. After the end cover 2 is fixedly connected to the winding tube 1 by four screws, injection molding is performed to form the outer skin 8 of the handle, thereby sealing the heating wire 11 and the connection point with the power cord 6.

[0053] It should be noted that the circular tube section of the magnetic steel seat 4 passes through the throttle housing 3, and the winding tube 1 and the end cover 2 are connected by screws and then sleeved on the magnetic steel seat 4. Since the outer wall of the circular tube section of the magnetic steel seat 4 is snap-fitted with the end cover 2, the magnetic steel seat 4, the end cover 2, the winding tube 1 and the throttle outer skin 8 form a throttle dynamic body.

[0054] According to some embodiments of the present application, a plurality of connecting plates 21 are circumferentially spaced apart on the side of the end cover 2 facing away from the winding tube 1 , and at least some of the plurality of connecting plates 21 are provided with card grooves 211 that are adapted to the plurality of card blocks 42 on the outer wall of the magnetic steel seat 4 .

[0055] Specifically, the connecting piece 21 can be set to be an arc shape, distributed around the central through hole of the end cover 2, and a plurality of clamping blocks 42 are distributed on the circular tube section of the magnetic steel seat 4, which are adapted to the clamping groove 211 on the connecting piece 21. During installation, the circular tube section of the magnetic steel seat 4 is inserted into the central through hole of the end cover 2, and the clamping block 42 will enter the clamping groove 211 to form a clamping fit, so that the magnetic steel seat 4 is fixedly connected to the end cover 2.

[0056] It should be noted that the circumferential spacing area between adjacent connecting pieces 21 can form a limit groove 25, and a plurality of limit blocks 43 are correspondingly provided on the magnetic steel seat 4, and at least part of the limit blocks 43 extend into the winding tube 1 and form a snap fit with the inner wall slot. After the block 42 on the magnetic steel seat 4 enters the slot 211 on the connecting piece 21, the axial displacement between the two is limited, but the magnetic steel seat 4 and the end cover 2 can still rotate slightly in the circumferential direction, so the limit block 43 is provided on the magnetic steel seat 4 to cooperate with the limit groove 25 on the end cover 2 to limit the circumferential rotation between the two.

[0057] According to some embodiments of the present application, at least two baffles 22 are circumferentially spaced apart on the outer sides of the multiple connecting plates 21, a wire clamping groove 23 is formed between the at least two baffles 22 and the multiple connecting plates 21, and a wire threading hole 24 and four screw holes 26 are axially penetrated on the end cover 2.

[0058] Specifically, the blocking piece 22 can be set to be an arc shape and distributed around the central through hole of the end cover 2; the screw hole 26 corresponds to the screw hole on the winding tube 1, and the winding tube 1 and the end cover 2 are connected together with four screws.

[0059] During installation, after one end of the power cord 6 enters the wire threading hole 24, the power cord 6 can be first wrapped and bound in the wire clamping groove 23, and then coiled in the first cavity along the circumferential direction. In this way, when the handlebar moving body rotates, the power cord 6 can be freely retracted and released in an involute manner in the first cavity on the inner side of the handlebar housing 3, which solves the problem of the power cord rotating with the rotation of the handlebar.

[0060] According to some embodiments of the present application, the throttle housing 3 is provided with a power cord groove 33 on the side facing the end cover 2, and the power cord 6 is arranged in the power cord groove 33 through a fixing wire 61, and is fixed to the throttle housing 3 by bolting through a pressure plate 34.

[0061] Specifically, the power cord groove 33 is arranged along the radial direction of the throttle housing 3 and is connected to the first cavity inside the throttle housing 3, and the power cord 6 can extend into the first cavity through the power cord groove 33. After the power cord 6 is placed in the power cord groove 33, the pressure plate 34 is fixed to the side of the power cord groove 33 by screws, thereby fixing the power cord 6.

[0062] According to some embodiments of the present application, a spiral winding groove is provided on the outer wall of the winding tube 1, and the heating wire 11 is wound in the winding groove. Specifically, the winding groove is arranged in a spiral line along the axial direction of the winding tube 1, and the heating wire 11 is wound in the winding groove, so that the heating wire 11 can be better positioned on the outer wall of the winding tube 1.

[0063] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model.
