[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6A new type of heated handlebar for an electric vehicle comprises a support 20 and a rotating tube 4 which can rotate relative to the support 20, an electric heating wire 402 is wound around the rotating tube 4 and a flange portion 405 is formed at one end, a handlebar skin 3 is sleeved on the rotating tube 4 to wrap the electric heating wire 402, a power cord tray 7 fixedly connected to the flange portion 405 is provided between the flange portion 405 and the support 20, a power cord 10 for supplying power to the electric heating wire 402 is coiled with a plurality of turns coaxially with the power cord tray 7 at least on the end surface of the power cord tray 7 facing the support 20, when the rotating tube 4 rotates, the power cord tray 7 is used to make the power cord 10 coiled on the power cord tray 7 freely extend and retract in an arc shape, here, the number of coils of the power cord 10 can be any number of turns within the range of 1 to 2 turns, or can be 2, 3 or more turns, and the handlebar skin 3 is wrapped around the rotating tube 4 by a secondary encapsulation method of an injection molding machine.

[0024] As a preferred embodiment, a threading hole 404 is provided on the power cord tray 7 and the boss 403. One end of the power cord 10 passes through the threading hole 404 and is connected to the electric heating wire 402. The other end of the power cord 10 is connected to the wiring point on the support 20. The threading hole 404 is located in an annular groove 802 area along the displacement trajectory of the rotating tube 4 when it rotates.

[0025] Through the above arrangement, the power cord 10 is spirally coiled on the power cord tray 7, one end of which passes through the threading hole 404 and is connected to the electric heating wire 402, and the other end is connected to the wiring point on the support 20. When the user rotates the rotating tube 4, the power cord tray 7 rotates synchronously therewith. At this time, due to the limitation of the threading hole 404 on one end of the power cord 10 and the limitation of the wiring point on the support 20 on the other end, the power cord 10 coiled on the power cord tray 7 will freely expand and contract in an arc shape, which completely solves the shortcomings of power supply through contacts or springs in the prior art, and has the advantages of stable electrical connection and long service life of the power cord.

[0026] Preferably, the power cord tray 7 is provided with a plurality of limiting members 701 for limiting the displacement amplitude of the power cord 10 wound on the power cord tray 7 in the radial direction of the power cord tray 7; further preferably, the limiting member 701 is a door frame structure, and the power cord 10 is wound in an annular area formed by the door frames of the plurality of limiting members 701. Here, the limiting member 701 can be set as a structure in which the door frame is inverted on the power cord tray 7, or can be set as a structure in which the door frame opens outward. In this embodiment, preferably, three limiting members 701 are arranged evenly distributed on the power cord tray 7 in the circumferential direction and the door frame is inverted on the power cord tray 7. In this way, the power cord 10 passes through the door frames of each limiting member 701 in turn when being wound, so as to avoid the power cord 10 from being scattered and the power cord 10 from being stuck in the rotation gap of each component, thereby further ensuring the service life of the power cord 10 and the stability of the electrical connection.

[0027] Preferably, a boss 403 is formed axially on the flange portion 405, the magnet 5 is snap-mounted in a snap-mounting groove 401 formed on the outer wall of the boss 403, and the Hall mounting seat 8 is installed between the boss 403 and the power cord tray 7 and can be rotatably arranged relative to the power cord tray 7 and fixedly connected to the support 20; a accommodating cavity 801 is formed on the side wall of the Hall mounting seat 8 for installing a Hall sensor 9, and the Hall sensor 9 is installed to detect the circumferential position of the magnet 5. As a preferred embodiment, a partition ring 804 is provided in the axial middle part of the Hall mounting seat 8, and a convex ring 803 is formed axially on the partition ring 804 toward one end of the support 20. An annular groove 802 is also arranged between the outer wall of the convex ring 803 and the inner wall of the Hall mounting seat 8. When the power cord tray 7 is connected to the boss 403 through the fastener 30, the power cord tray 7 and the adjacent end faces of the partition ring 804 are slidably abutted and the fastener 30 is located in the annular groove 802 area. The arc length of the annular groove 802 is adapted to the rotation arc length of the rotating tube 4. Here, the focus is on reference Figure 3 and Figure 4 It can be understood that the Hall mounting seat 8 is a thin-walled cylindrical structure, and the fastener 30 is a self-tapping screw. In this way, the connecting body composed of the rotating tube 4 and the power cord tray 7 can rotate freely relative to the Hall mounting seat 8, and the anti-pull-off ability is enhanced. Here, it can be understood that in this embodiment, when the power cord tray 7 is connected to the boss 403 through the fastener 30, the Hall mounting seat 8 also forms a radial and axial sliding fit with the outer peripheral wall of the boss 403 and the end face of the flange portion 405, respectively, so that it can be ensured that the rotating tube 4 can drive the power cord tray 7 to rotate smoothly without looseness. Of course, the matching position for limiting the radial and axial freedom between the Hall mounting seat 8 and the rotating tube 4 can also be set at other positions, which is also within the protection scope of this technical solution.

[0028] Preferably, the outer wall of the Hall mount 8 facing the flange portion 405 at least covers the boss 403, the outer wall end face of the Hall mount 8 facing the support 20 abuts against the support 20, and the support 20 is fixedly connected to the convex ring 803 by the corresponding fastener 30. Further preferably, the limiting member 701 and the coiled portion of the power cord 10 are located in the space formed by the power cord tray 7, the outer wall of the convex ring 803, the inner wall of the Hall mount 8 and the support 20. Through the above arrangement, the power cord 10 is arranged inside, which has the advantages of good protection and perfect appearance, and enables the connection body composed of the rotating tube 4 and the power cord tray 7 to rotate freely relative to the Hall mount 8.

[0029] Preferably, the inner wall of the boss 403 forms a cavity for accommodating the torsion spring 6. When the external force of twisting the rotating tube 4 disappears, the torsion spring 6 is used to reset the rotating tube 4. In this way, when the vehicle stops running and the driver's hand leaves the handlebar, the rotating tube 4 automatically returns to its position. At this time, the magnet 5 circumferentially leaves the detection area of ​​the Hall sensor 9. At this time, the Hall sensor 9 transmits a signal to the electronic control system to cut off the power supply to the electric heating wire 402, thereby achieving an energy-saving effect. Conversely, when the vehicle is in use, the Hall sensor 9 sends a signal to supply power to the electric heating wire 402 when the handlebar is twisted to make the vehicle move, thereby achieving automatic control. Here, the installation method of the torsion spring 6 can adopt the existing technology.

[0030] Preferably, an open inner cavity 2001 is provided at the outer end of the support 20, and an open locking aluminum ring 1 is installed in the inner cavity 2001. The locking bolt 2 passes through a step hole 2002 provided on the side wall of the support 20 and is screwed into the threaded hole on the locking aluminum ring 1. In this way, the new electric vehicle heating handlebar is conveniently connected to the corresponding parts of the electric vehicle.
