[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0033] The present application aims to provide a heating handlebar with waterproof and anti-electric shock functions, and the heating part is more uniform and safer.

[0034] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be described in further detail below with reference to the drawings and specific embodiments.

[0035] In the exemplary embodiment, the utility model provides a kind of heating handle.The heating handle includes handle core, heating wire and outer rubber cover.The heating handle is used to be installed on the handle tube of handle type vehicle such as electric vehicle or motorcycle and use.

[0036] As Figure 1 And Figure 2 The handle core includes connecting portion 1 and main body portion 2, and is hollow cylindrical as a whole of plastic material, and is prepared by die integrated molding.The main body portion 2 of the handle core is designed as hollow cylindrical as a whole approximately.The connecting portion 1 of the handle core is designed as hollow circular table as a whole approximately.The connecting portion 1 is located at one side of the main body portion 2, for example, vehicle right handle is shown in the figure, then connecting portion 1 is located at the left side of main body portion 2.If it is used for the left handle of vehicle, it should be symmetrically arranged with the right handle.

[0037] As Figures 1 to 3 The main body portion 2 is provided with multiple turns of heating wire embedding entrance 3 on outer surface, for embedding type winding heating wire.The heating wire used in the utility model is wrapped with waterproof insulation layer, for example, can be lacquer layer or glue layer, with waterproof, anti-electric shock function, effectively avoid various defects of using bare heating wire.The diameter of the heating wire is usually 0.3-1.5mm.Therefore, the depth of the heating wire embedding entrance of the utility model is 0.4-1.6mm, which is 0.1mm larger than the diameter of the heating wire, to ensure that the wound heating wire does not protrude from the surface of handle core.

[0038] In practical application, heating wire can be wound along the circumference or axial direction of main body portion 2, so the heating wire embedding entrance 3 can be arranged as spiral along the circumference, or as parallel along the axial direction.For multiple turns of heating wire embedding entrance 3 arranged along the circumference, the distance between adjacent two turns of heating wire embedding entrance 3 is 1-3 times of the diameter of the heating wire.

[0039] As Figures 1 to 3As shown, the outer surface of the main body 2 near the connecting part 1 is also provided with a protector mounting groove 4 for embedding a fireproof protector. The protector mounting groove 4 includes a chip groove 401 and two pin grooves 402 which are in communication with each other, and matches the shape of the fireproof protector. The size of the protector mounting groove 4 is set according to the size of the fireproof protector, and the principle is that the size of the protector mounting groove 4 should be slightly larger than the overall size of the fireproof protector. For example, in a specific embodiment, the fireproof protector adopts a square temperature fuse of X9 model and 136 degrees 3A, and the main body chip part is approximately a cuboid with a size of 6.5mm long x 5.7mm wide x 2.3mm thick. The size of the chip groove 401 is designed to be 6.6mm long x 5.8mm wide x (2.4+(0.4-1.6))mm deep; wherein 0.4-1.6mm is the depth of the heating wire embedding entrance above the chip groove 401. The depth of the two pin grooves 402 is the same as that of the chip groove 401, and the length can be set to 3-5 times the length of the chip groove 401 as needed, and the width needs to be 0.1mm wider than the pin of the fireproof protector.

[0040] In use, first place the fireproof protector in the protector mounting groove 4. Then wrap the heating wire around the outer surface of the main body 2 along the multi-turn heating wire embedding entrance 3. The depth of the protector mounting groove 4 should be greater than the depth of the heating wire embedding entrance 3. That is, the fireproof protector is located below the wound heating wire, so it will not interfere with the wound heating wire. After all the heating wires are wound, cover the outer sleeve on the outer surface of the handle core. In manufacturing, the outer sleeve can be made by integral injection molding process together with the handle core, or the outer sleeve can be made by using external force to cover the handle core.

[0041] In use, the fireproof protector is connected in series with the heating wire and the power supply provided by the vehicle. When the temperature of the heated handle reaches the melting temperature of the fireproof protector, the alloy wire in the fireproof protector melts, thereby cutting off the power supply and avoiding the occurrence of fire accidents. The connection points of the heating wire, the power supply, the wire or other elements can be riveted or welded, and then the connection points are inserted into the heat shrink tube or sealed with glue to prevent corrosion of the connection points when encountering water.

[0042] The electric heating wire of the utility model is wrapped with waterproof insulation layer, even if rainwater enters the handle core, electrolytic water reaction does not occur, the risk of corrosion and breakage of the electric heating wire is avoided, the service life of the electric heating wire is prolonged, and there is no risk of electric shock. The multiple turns of electric heating wire can be more evenly wound on the surface of the handle core along the electric heating wire embedding entrance, there is no heating blind area, the heating position is more uniform, and the embedded winding mode is very convenient to operate. Further, since the protector mounting groove 4 and the electric heating wire embedding entrance 3 are arranged, the installed combustion protector and the wound electric heating wire do not protrude from the surface of the handle core, and the slipping or bulging of the outer rubber sleeve and the handle core is avoided.

[0043] Further, as shown in Figure 2 、 4 , 6, 7, 10, 11, four outwardly protruding ridge portions 5 are uniformly arranged on the outer surface of the main body portion 2 in the circumferential direction, and the protruding thickness of the ridge portion 5 is generally 0.5-5mm. The outer surface of the ridge portion 5 is used to directly contact the inner surface of the outer rubber sleeve, which can effectively prevent the outer rubber sleeve from slipping with the handle core. Through the arrangement of the ridge portion 5, the slipping of the outer rubber sleeve and the handle core can be more effectively prevented, so that the outer rubber sleeve is better combined with the handle core. Since the electric heating wire also needs to be wound at the ridge portion 5, the electric heating wire embedding entrance 3 is also provided thereon.

[0044] Further, as shown in Figures 5 to 11 , a heat insulation ring 6 in the form of inwardly protruding sawtooth is arranged on the inner surface of the main body portion 2 in the circumferential direction. The protruding height of the heat insulation ring 6 is 0.5-3mm. Further, an inwardly protruding fixing strip 7 is also arranged on the inner surface of the main body portion 2 in the axial direction. The fixing strip 7 is connected with the heat insulation ring 6. As described above, the heating handle of the utility model is used for sleeving on the handle pipe of a vehicle such as an electric vehicle or a motorcycle, and the handle pipe of the vehicle such as the electric vehicle or the motorcycle is generally a stainless steel pipe with heat conduction effect. Therefore, the inwardly protruding heat insulation ring 6 and the fixing strip 7 are arranged on the inner surface of the main body portion 2, which can not only play a heat insulation effect between the handle pipe and the handle core, but also ensure the stable connection between the handle pipe and the handle core. As shown in Figures 1 to 11 , the inner and outer surface shapes of the connecting portion 1 need to match the shape of the handle pipe of the vehicle.

[0045] In one specific embodiment, the inner diameter of the circular ring surrounded by the sawtooth protrusion of the heat insulation ring 6 is 22mm; the inner diameter of the cylindrical main body portion 2 without the heat insulation ring 6 is 24.5mm. The outer diameter of the cylindrical main body portion 2 without the ridge portion 5 is 27.5mm; the protruding thickness of the ridge portion 5 is 2.5mm; therefore the outer diameter of the circular ring surrounded by the outer surface of the ridge portion 5 is 30mm.

[0046] In another exemplary embodiment, as shown inFigures 12 to 15 As shown, the outer surface of the main body 2 near one side of the connecting portion 1 is also provided with a sensor mounting groove 8. The sensor mounting groove 8 and the protector mounting groove 4 are located at different positions in the circumferential direction of the main body 2. Preferably, the sensor mounting groove 8 and the protector mounting groove 4 are arranged opposite in the radial direction. The sensor mounting groove 8 is used to embed a temperature sensor. Specifically, the sensor mounting groove 8 includes a sensor groove 801 and two sensor pin grooves 802 which are in communication with each other, and matches the shape of the temperature sensor. The size is set according to the size of the temperature sensor, and the principle of setting is that the size of the sensor mounting groove 8 should be slightly larger than the overall size of the temperature sensor. For example, in one specific embodiment, the temperature sensor adopts MF58-10K glass-sealed precision NTC thermistor, and the main sensor part is a cylinder with a diameter of 1.8 mm and a length of 5.5 mm. The sensor groove 801 should be designed as a cuboid groove with a length of 5.6 mm, a width of 1.9 mm and a depth of (1.9+(0.4-1.6)) mm. The depth of the sensor groove 801 is 0.4-1.6 mm, which is the depth of the heating wire embedding entrance above the sensor groove 801. The depth of the two sensor pin grooves 802 is the same as that of the sensor groove 801, and the length can be set to 3-5 times the length of the sensor groove 801 as needed, and the width needs to be 0.1 mm wider than the pin of the temperature sensor. The temperature sensor is also located below the wound heating wire, so it will not interfere with the wound heating wire. The temperature sensor is used to detect the temperature of the heating handle, and transmit the detected temperature data to the single-chip microcomputer on the vehicle, thereby realizing the temperature regulation function. The temperature regulation function can be realized by using conventional technology, which will not be described here.
