In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0030] The embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0031] Embodiment 1:

[0032] like Figure 1-Figure 9 As shown, an electric heating handle comprises a fixing base 1 for mounting and fixing on a vehicle body, an inner handle 2 rotatably connected to the fixing base 1, a handle cover 3 fixed on the inner handle 2, and an electric heating element. In a specific embodiment of the utility model, it also comprises an annular chamber 4 opened inside the fixing base 1 and two electric wires wrapped around the inner wall of the annular chamber 4, a through hole 5 is opened on the inner handle 2 for the two electric wires to pass through and connect with the electric heating element, the through hole 5 is communicated with the annular chamber 4, and a connecting port 6 is opened on the side wall of the fixing base 1 for the other ends of the two electric wires to pass through.

[0033] The above-mentioned electric heating handle is adopted, and an annular chamber 4 is opened inside the fixing base 1, the wiring is wrapped around the inner wall of the annular chamber 4, and a through hole 5 is opened on the inner handle 2 which is rotatably connected to the fixing base 1, so that when the inner handle 2 is rotated during daily use, the two wires supplying power to the electric heating element will expand outward inside the annular chamber 4, while their two ends remain stationary relative to the through hole 5 and the connecting port 6. The power supply wiring structure of the present application is simple, the production cost is low, the wiring structure is reasonable, no displacement will occur at the two ends, and the service life is long. The two wires are not shown in the figure.

[0034] Embodiment 2:

[0035] The difference from Example 1 is that, in addition to the structural features of the aforementioned embodiments, in the specific embodiment of the present utility model, the two electric wires are wound around the inner wall of the annular chamber 4 at least once.

[0036] The two wires are used to supply power to the electric heating element. In order to facilitate its expansion movement inside the fixing base 1, they are arranged to surround the inner wall of the annular chamber 4 for at least one circle, so as to facilitate the expansion of the wires inside the fixing base 1 while avoiding stretching or twisting, thereby further improving the service life of the wires.

[0037] like Figure 3 As shown, in the specific embodiment of the utility model, in order to provide space for the movement of the wire, an arc hole 7 connected to the annular chamber 4 is opened on the side wall of the fixing seat 1 facing the inner handle 2. The maximum rotatable angle of the inner handle 2 is smaller than the curvature of the arc hole 7, so that when the inner handle 2 rotates, one end of the through hole 5 rotates in the arc hole 7. Generally speaking, the rotation of the handle is to hold the handle sleeve 3 with the right hand. Figure 3In the figure, the handle cover 3 is rotated counterclockwise, while the handle cover 3 and the inner handle 2 are relatively stationary. After the two wires pass through the through hole 5, they are connected to the electric heating element between the handle cover 3 and the inner handle 2, that is, the parts of the two wires passing through the through hole 5 are relatively stationary with the electric heating element, the handle cover 3 and the inner handle 2 while the handle cover 3 is rotated. As for the two wires in the annular chamber 4, since the arc hole 7 is provided, the connecting section of the two wires and the through hole 5 can move along the curvature direction of the arc hole 7, thereby making the two wires expand outward inside the annular chamber 4.

[0038] In a specific embodiment of the utility model, a connecting block 8 is connected to the inner handle 2 and located in the arc-shaped hole 7 , and the through hole 5 is configured to penetrate the connecting block 8 and the inner handle 2 .

[0039] In order to further provide the guiding stability of the connection between the two wires and the through hole 5, a connecting block 8 is connected to the inner handle 2 and located in the arc hole 7. The through hole 5 is arranged to pass through the connecting block 8 and the inner handle 2. The connecting block 8 can lengthen the through hole 5, thereby enhancing the stability. Figure 3 As shown, the height difference between the connecting ends of the two wires and the connecting block 8 and the annular wall of the annular chamber 4 can be greatly reduced, so that when the handle is rotated, the wires inside the annular chamber 4 can be guided to expand outward.

[0040] Embodiment 3:

[0041] The difference from Example 2 is that, in addition to including the structural features of the previous embodiment, such as Figure 3 As shown, in a specific embodiment of the utility model, a clamping assembly for clamping and fixing the electric wire is arranged inside the annular chamber 4 and between the connecting port 6 and the through hole 5, and the clamping assembly includes a first clamping block 9 fixed on the inner wall of the annular chamber 4, and a first clamping groove 10 for the power supply line to pass through is formed between the first clamping block 9 and the outer ring wall of the annular chamber 4.

[0042] Although the expansion movement stroke of the two wires wound at least one circle inside the annular chamber 4 can reach the level of normal use, in order to further avoid relative displacement of the wires at the connecting port 6, a clamping assembly for clamping and fixing the wires is provided inside the annular chamber 4 and between the connecting port 6 and the through hole 5. The clamping assembly includes a first clamping block 9 fixed on the inner wall of the annular chamber 4, and a first clamping groove 10 for the power supply line to pass through is formed between the first clamping block 9 and the outer ring wall of the annular chamber 4. The groove width of the first clamping groove 10 is approximately equal to the width of one wire, and can also be slightly smaller than the width of one wire, and two wires can be clamped in the first clamping groove 10 up and down.

[0043] Embodiment 4:

[0044] The difference from Example 3 is that, in addition to including the structural features of the previous embodiment, Figure 3 As shown, in a specific embodiment of the utility model, the clamping assembly also includes a second clamping block 11 arranged on the inner wall of the annular chamber 4 and located between the first clamping block 9 and the inner wall of the annular chamber 4, and a second clamping groove 12 is formed between the first clamping block 9 and the second clamping block 11.

[0045] A second clamping block 11 is arranged between the first clamping block 9 and the inner wall of the annular chamber 4, and a second clamping groove 12 is formed between the first clamping block 9 and the second clamping block 11. The two wires can be clamped in the first clamping groove 10 and the second clamping groove 12 respectively, which makes it more convenient to shunt the two wires and further improve the stability of their expansion movement.

[0046] Embodiment 5:

[0047] The difference from Example 3 is that, in addition to including the structural features of the previous embodiment, Figure 7-Figure 9 As shown, in a specific embodiment of the utility model, a connecting ring 14 is connected to one end of the fixing seat 1 facing the inner handle 2. The inner handle 2 is in the shape of a circular ring column, and two fixing blocks 15 are arranged on the inner ring wall at one end. Two arc guide grooves 16 are arranged on the connecting ring 14 along the circumferential direction. After the connecting ring 14 is inserted into one end of the inner handle 2, the two fixing blocks 15 slide correspondingly in the two arc guide grooves 16, so that the inner handle 2 is rotatably connected to the fixing seat 1.

[0048] like Figure 8 As shown, an outer ring is also provided on the edge of one end of the fixing seat 1 facing the inner handle 2. Fig. 9 The inner handle 2 in the middle is rotated and contacted with the inner wall of the outer ring during installation, and the connecting ring 14 of the fixing seat 1 is inserted into the circular cylindrical head of the inner handle 2, and the two fixing blocks 15 of the inner handle 2 enter the two arc-shaped guide grooves 16. As the handle rotates, the two fixing blocks 15 slide in the two arc-shaped guide grooves 16, so that the inner handle 2 is rotationally connected to the fixing seat 1.

[0049] In a specific embodiment of the present utility model, Figure 8 and Fig. 9 As shown, an arc-shaped outer groove 21 is provided at one end of the fixing seat 1 facing the inner handle 2 and located on the outside of the connecting ring 14, an arc-shaped plate 22 is connected to the end of the inner handle 2 and located in the arc-shaped outer groove 21, and an arc-shaped spring is provided at one end of the arc-shaped plate 22 and located in the arc-shaped outer groove 21.

[0050] The arc spring is not shown in the figure. In order to facilitate the rotation of the handle, the inner handle 2 is rotated and reset when no power is needed, and to provide a feel when the inner handle 2 is rotated, an arc spring is provided at one end of the arc plate 22 and located in the arc outer groove 21. When the inner handle 2 is rotated, the arc spring is compressed, causing the arc spring to deform in the arc outer groove 21. When the inner handle 2 is released, the inner handle 2 can be rotated and reset under the resetting action of the arc spring.

[0051] Embodiment 6:

[0052] The difference from Example 5 is that, in addition to including the structural features of the previous embodiments, Figure 1-Figure 9 As shown, in a specific embodiment of the utility model, an outer cover 13 for opening and closing the annular chamber 4 is provided at one end of the fixing seat 1 away from the inner handle 2, and an open box structure 23 is formed between the connecting port 6 and the annular chamber 4, and the outer cover 13 is divided into an annular cover 131 for covering the annular chamber 4 and a box cover 132 for covering the opening of the box structure 23, at least two mounting screw holes are provided in the annular chamber 4, and the annular cover 131 is installed in the mounting screw holes by studs to close the annular chamber 4, and at least one mounting hole is provided in the box structure 23, and the box cover 132 is installed in the mounting hole by studs to cover the opening of the box structure 23.

[0053] The outer cover 13 is divided into an annular cover 131 for covering the annular chamber 4 and a box cover 132 for covering the opening of the box body structure 23, so that they can be installed in sequence. During installation, the annular cover 131 is first covered on the annular chamber 4, and then it is installed and fixed with studs. The annular cover 131 is installed first, and the box cover 132 is installed later. The wires can also be arranged before installing the box cover 132. At the same time, the structure of the box body structure 23 further extends the distance from the first clamping block 9 to the connecting port 6, ensuring that the wires will not be displaced due to the rotation of the handle after passing through the connecting port 6, further improving its stability and service life.

[0054] In a specific embodiment of the present utility model, Figure 6 As shown, the annular cover 131 is connected to an L-shaped pressing clamping block 133. When the annular cover 131 is installed on the fixing seat 1, a pressing hole for pressing two wires is formed between the pressing clamping block 133 and the side wall and bottom of the box structure 23.

[0055] You can see Figure 5 , Figure 6 and Figure 3After the two wires are clamped from the first clamping groove 10 and the second clamping groove 12, the annular cover 131 is installed on the fixing seat 1, so that the wires passing through the first clamping groove 10 and the second clamping groove 12 pass through the clamping hole formed by the downward clamping block 133 and the side wall and the bottom of the box structure 23. The clamping hole can cooperate with the first clamping block 9 and the second clamping block 11 to fully clamp and fix the two wires, so that the wires will not be displaced due to the rotation of the handle after passing through the connecting port 6, further improving its stability and service life.
