The handle cover body 1 includes a handle core tube 11 and a jacket 12 arranged outside the handle core tube 11; one end of the jacket 12 is provided with a mounting portion 13, and a base 14 is embedded inside the mounting portion 13. The base 14 is a hard material piece, such as plastic, metal, etc. The material of the base 14 is preferably plastic, which has a high cost performance. When the base 14 is made of metal, insulation should be done well in the design to prevent short circuit problems; the base 14 can play a role in the mounting portion 13 The base 14 is fixedly connected to the handle core tube 11, so that the base 14 is reliably fixed. The base 14 and the handle core tube 11 are fixedly connected by at least one of the following methods: snap connection, integral molding, adhesive bonding, welding (such as ultrasonic welding), and screw fixing; the base 14 is provided with a concave cavity 15 opening outward, the control module 2 is fixed in the concave cavity 15, and is electrically connected to the electric heating element. The electric heating element can be an electric heating wire or an electric heating sheet. During operation, the driver can control the working state of the electric heating element through the control module 2. With the structure in this embodiment, when the heating handle cover is assembled, after the control module 2 is assembled, the control module 2 is installed into the concave cavity 15 of the base 14 and fixedly connected to the base 14, so that the control module 2 is fixedly installed reliably; the base 14 and the outer cover 12 can be connected by integral injection molding, tight fitting nesting, glue bonding, etc.

[0034] See also Figure 3 As shown, the control module 2 includes a cover shell 21 with a hollow structure, and a circuit board 22 and a switch button 23 installed in the cover shell 21. The rear end of the cover shell 21 is provided with an opening 24, and the circuit board 22 is installed in the cover shell 21 through the opening 24 and fixed. A switch element 25 is provided on the circuit board 22, and the switch element 25 is preferably a micro switch or a touch switch. The switch button 23 is installed at the front of the cover shell 21 and is opposite to the switch element 25. The cover shell 21 is installed in the concave cavity 15 and the opening 24 faces the bottom of the concave cavity 15. When the control module 2 is controlled, the switch element 25 on the circuit board 22 is triggered by pressing the switch button 23, thereby switching and controlling the working state of the electric heating element. It is preferred that the base 14 and the cover shell 21 are snap-connected (for example, a snap-on platform is provided on the side wall of the cavity, and a snap-on hole that engages with the snap-on platform is provided on the side wall of the cover shell 21) to make assembly convenient and secure. In actual operation, the cover shell 21 can also be strengthened and fixed to the base 14 by means of gluing or screwing.

[0035] In order to enhance the protection performance of the circuit board 22, a soft rubber sheath 26 is coated on the front of the circuit board 22. The protective rubber sheath 26 can play a shielding and protective role, thereby preventing dust, water stains and other impurities that enter the cover 21 through the gap in the front of the control module 2 from contacting the circuit board 22, thereby enhancing the protection effect. The soft rubber sheath 26 can be made of soft rubber materials such as rubber or silicone.

[0036] like Figure 3 As shown, a protruding limit stop 27 is provided on the side of the switch button 23, and the limit stop 27 abuts against the inner side of the cover 21 to limit the switch button 23 and prevent the switch button 23 from falling off; the soft rubber sheath 26 is provided with a supporting protrusion 261 abutting against the limit stop 27, and the support protrusion 261 supports the switch button 23.

The outer sleeve 12 is provided with a through hole at a position corresponding to the threaded through hole. The fastening bolt 3 passes through the through hole and is screwed with the threaded through hole. After the fastening bolt 3 is tightened, its inner end extends into the inner cavity of the handle core tube 11. When the heating handle cover is installed, after the handle core tube 11 is put into place on the handlebar tube, the heating handle cover is locked by screwing the fastening bolt 3 so that its inner end is locked with the handlebar tube.

[0041] In order to enhance the reliability of the installation of the base 14 in the mounting portion 13, a edging 131 is provided on the mounting portion 13 to wrap the periphery of the outer port of the base 14, thereby strengthening the positioning of the base 14 and preventing cracks at the connection between the base 14 and the mounting portion 13; in order to further enhance the bonding force between the base 14 and the outer sleeve 12, a positioning protrusion 142 embedded in the mounting portion 13 is provided on the outside of the base 14, and the positioning protrusion 142 is embedded in the mounting portion 13 of the outer sleeve 12 to enhance the fixing firmness of the base 14.
