Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, specifically a universal connecting heated handlebar sleeve for electric vehicle handlebars. Background Technology

[0002] Electric bikes are an important mode of transportation for short-distance travel. Speed ​​is adjusted by rotating the handlebar grip. The grip mainly consists of a rubber sleeve and an inner core. The grip area and the corresponding part of the inner core are both cylindrical, and the two are directly fitted together. Installation is completed by simply slipping the grip onto the cylindrical handlebar. The friction between the inner core and the handlebar keeps the grip stable. However, this type of grip only works with cylindrical handlebars. With technological advancements, handlebars have gradually evolved into irregular shapes, such as tapered handlebars. It should be noted that tapered handlebars are two-section handlebars that combine a cylindrical section and a tapered section. When using tapered handlebars, the cylindrical grip no longer fits perfectly against the handlebar, especially the tapered section. This makes it impossible to guarantee a stable connection with the handlebars. To achieve a stable connection with the handlebars, it may even be necessary to replace the original Hall effect system. In addition, it should be considered that in low-temperature environments, such as outdoor riding in winter, people wear gloves when riding to avoid cold hands. However, the friction between gloves and handlebar grips is relatively low. The cylindrical handlebar grips are unstable in their connection with the tapered part of the handlebars. The combination of these two factors introduces significant safety risks into the riding process. Based on this situation, how to improve the stability of the connection between the handlebar grips and the tapered handlebars, while ensuring that hands do not get cold even when holding the handlebars without gloves, thereby guaranteeing riding safety, has become an increasingly urgent problem for relevant technicians to solve. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a universal connecting heated handlebar sleeve for electric vehicle handlebars.

[0004] A universal connecting heated handlebar sleeve for electric vehicle handlebars includes a rubber sleeve and an inner core. The rubber sleeve covers the surface of the inner core, with one end open and both ends open. A first cylindrical section is provided inside the inner core near the opening of the rubber sleeve, and a first tapered section is provided inside the inner core away from the opening of the rubber sleeve. The first tapered section connects to the first cylindrical section, and the inner diameter of the first cylindrical section remains consistent. The inner diameter of the first tapered section gradually decreases in the direction away from the first cylindrical section.

[0005] Furthermore, a groove is provided on the outer surface of the inner core, a heater is provided between the inner core and the rubber sleeve, an adhesive is provided on the inner wall surface of the heater, the heater is located inside the groove, and the adhesive is bonded to the groove.

[0006] Furthermore, a wire groove is provided on the inner side of the inner core near the opening of the rubber sleeve, and a wire hole is provided on the inner core near the opening of the rubber sleeve. A solder pad is provided on the end of the heater near the wire groove, and a wire is soldered to the solder pad. The wire is led out through the wire groove and the wire hole.

[0007] Furthermore, the surface of the rubber sleeve is provided with anti-slip texture.

[0008] Furthermore, the sleeve is made of rubber or silicone, and the inner core is made of plastic, silicone, or rubber.

[0009] Furthermore, an adjusting core can be provided inside the inner core. In this case, the outer wall of the adjusting core is in contact with the inner wall of the inner core. The adjusting core has openings at both ends. A second cylindrical section is provided at the end of the adjusting core near the opening of the rubber sleeve, and a second conical section is provided at the end of the adjusting core away from the opening of the rubber sleeve. The second conical section is connected to the second cylindrical section. The outer diameter of the second cylindrical section is consistent. The outer diameter of the second conical section gradually decreases in the direction away from the second cylindrical section. The inner diameter of the adjusting core is consistent.

[0010] Furthermore, a locking block is provided at one end of the adjusting core near the opening of the rubber sleeve, and a locking groove is provided inside the inner core at one end near the opening of the rubber sleeve. When the adjusting core and the inner core are assembled, the locking block engages with the locking groove, and the inner wall surface of the adjusting core is provided with protruding bands in a ring array.

[0011] Furthermore, the adjustment core is made of plastic.

[0012] The beneficial effects of this utility model of a universal connecting heated handlebar sleeve for electric bicycle handlebars are as follows:

[0013] 1. The first cylindrical section can fit snugly against the cylindrical part of the tapered handlebar, and the first tapered section can fit snugly against the tapered part of the tapered handlebar. Even if the taper of the first tapered section and the tapered part of the tapered handlebar are slightly different, the elasticity of the material gives the inner core so that the first tapered section and the tapered part of the tapered handlebar can fit snugly against each other. This effectively ensures the friction between the inner core and the tapered handlebar, and effectively improves the stability of the connection between this grip and the tapered handlebar. This improved connection stability means that this grip does not need to replace the original Hall system in order to achieve a stable connection with the handlebar, as is the case with other existing grips. This avoids damage to the original vehicle and effectively saves installation costs.

[0014] The heater gives this grip a heating function, so your hands won't get cold even if you hold the handlebars without gloves. The adhesive backing and groove bonding, the cable leading out through the cable channel and hole, and the rubber sleeve covering the inner core effectively prevent the heater from shifting irregularly, thereby further improving the stability of the connection between this grip and the tapered handlebars.

[0015] This effectively ensures cycling safety;

[0016] 2. The adjustment core is located inside the inner core, and its outer surface fits snugly against the inner core. The locking block engages with the locking slot, effectively ensuring the stability of its connection with the inner core. The inner diameter of the adjustment core remains consistent, effectively ensuring the stability of its connection with the cylindrical handlebar. The material gives the inner core and adjustment core elasticity, further enhancing the stability of the connection between the adjustment core and the inner core and the cylindrical handlebar. This allows the grips to connect stably even with cylindrical handlebars, effectively improving the applicability of the grips. Attached Figure Description

[0025] Furthermore, a wire groove 6 is provided on the inner side of the inner core 9 near the opening of the rubber sleeve 2, and a wire hole 7 is provided on the inner core 9 near the opening of the rubber sleeve 2. A solder pad 4 is provided on the end of the heater 5 near the wire groove 6. A wire is soldered to the solder pad 4, and the wire is led out through the wire groove 6 and the wire hole 7.

[0026] Furthermore, the surface of the rubber sleeve 2 is provided with anti-slip texture 3.

[0027] Furthermore, the sleeve 2 is made of rubber or silicone, and the inner core 9 is made of plastic, silicone, or rubber. Example

[0028] The following technical features can be added based on Example 1.

[0029] Furthermore, an adjusting core 1 can be provided inside the inner core 9. At this time, the outer wall of the adjusting core 1 is in contact with the inner wall of the inner core 9. The adjusting core 1 has openings at both ends. A second cylindrical section 10 is provided at the end of the adjusting core 1 near the opening of the rubber sleeve 2, and a second conical section 11 is provided at the end of the adjusting core 1 away from the opening of the rubber sleeve 2. The second conical section 11 is connected to the second cylindrical section 10. The outer diameter of the second cylindrical section 10 is consistent, and the outer diameter of the second conical section 11 gradually decreases in the direction away from the second cylindrical section 10. The inner diameter of the adjusting core 1 is consistent.

[0030] Furthermore, a locking block 14 is provided at one end of the adjusting core 1 near the opening of the rubber sleeve 2, and a slot 16 is provided inside the inner core 9 at one end near the opening of the rubber sleeve 2.

[0031] Furthermore, the adjustment core 1 is made of plastic.

[0032] The working principle of this utility model of a universal connecting heated handlebar cover for electric bicycle handlebars is as follows: The handlebar cover is positioned facing a tapered handlebar. In this case, there is no need to select an adjustment core 1. The heater 5 is placed inside the groove 8, and the heater 5 is pressed to bond the adhesive backing to the groove 8. After the wires are soldered and led out, the rubber sleeve 2 is wrapped around the surface of the inner core 9 using an overmolding process. This completes the processing of the handlebar cover. The handlebar cover is then placed on the surface of the tapered handlebar. The fitting method is to place the end of the inner core 9 closest to the opening of the rubber sleeve 2 onto the end of the tapered handlebar. The entire handlebar cover is then pushed towards the other end of the tapered handlebar until the end of the tapered handlebar touches the closed end of the rubber sleeve 2. At this point, the first cylindrical section 13 is in contact with the cylindrical part of the tapered handlebar, and the first tapered section 12 is in contact with the tapered part of the tapered handlebar. Even if the first tapered section 12 and the tapered part... The taper of the tapered part of the handlebar is slightly different. The elasticity of the inner core 9 given by the material allows the first tapered section 12 to fit as closely as possible to the tapered part of the handlebar. This completes the installation of the grip. The friction between the inner core 9 and the tapered handlebar is continuously guaranteed, effectively improving the stability of the connection between the grip and the tapered handlebar. When facing a cylindrical handlebar, insert the adjusting core 1 into the inner core 9 until the locking block 14 engages with the locking slot 16. At this time, the outer wall of the adjusting core 1 fits against the inner wall of the inner core 9, and the adjusting core 1 remains stable inside the inner core 9. Put the grip on the cylindrical handlebar. At this time, the convex strip 15 fits against the cylindrical handlebar. With the elasticity given by the material, the stability of the connection between the adjusting core 1, the inner core 9, and the cylindrical handlebar is further enhanced. This completes the installation of the grip.
