[0024] 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.

[0025] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0026] See also Figure 1-Figure 5 As shown, a heating structure for an exterior rearview mirror of a motor vehicle comprises a lens 1, a shell 3 and a heating wire 4. A heating component 2 is arranged on one side of the lens 1. The heating component 2 is used to control the path and position of the heating wire 4. The heating component 2 comprises a plurality of fixed disks 201 which are slidably connected to the outer wall of the lens 1. The heating wire 4 is located between the plurality of fixed disks 201. The heating wire 4 is wound around the fixed disks 201. A fixing rod 202 is arranged on one side of the fixed disk 201. A connecting block 203 is arranged on one end of the fixing rod 202 away from the fixing disk 201. A fixing ring 204 is arranged on one side of the connecting block 203. The plurality of connecting blocks 203 are rotatably connected to the outer wall of the fixing ring 204. A cylinder 205 is fixedly installed on the inner wall of the shell 3. The telescopic end of the cylinder 205 corresponds to the fixing ring 204.

[0027] The heating wire 4 does not directly contact the surface of the lens 1, so as to avoid the high-temperature heating wire 4 directly contacting the lens 1 and causing damage or deformation of the lens 1. The cylinder 205 drives the fixing ring 204 to move, and the fixing ring 204 drives the connecting block 203 and the fixing rod 202 to move together when moving. The multiple fixing plates 201 spread the heating wire 4, so the fixing plates 201 move with the fixing rod 202 and drive the heating wire 4 to shrink inward or expand outward.

[0028] When the fixing ring 204 moves toward the inner wall of the outer shell 3, it will pull the multiple fixing plates 201 to gather toward the middle of the lens 1, and then make the heating wire 4 move toward the middle of the lens 1. When the fixing ring 204 moves toward the direction of the lens 1, it will push the multiple fixing plates 201 to expand outwards, and then make the heating wire 4 expand outwards, thereby increasing the heating area of ​​the heating wire 4 and making the lens 1 heated more evenly.

[0029] See also Figure 3-Figure 4The connecting block 203 is provided with a square groove 7, and a rotating rod 8 is fixedly installed on the inner wall of the square groove 7. One end of the fixing rod 202 is located inside the square groove 7 and is rotatably connected to the outer wall of the rotating rod 8.

[0030] The square groove 7 provides a rotation space for one end of the fixing rod 202. The connecting block 203 is connected to the fixing rod 202 through the rotating rod 8, so that the fixing rod 202 can rotate along the outer wall of the rotating rod 8. Since the distance between each corner of the lens 1 and the fixing ring 204 is different, the degree of tortuosity between each connecting block 203 and the fixing rod 202 is different. The rotating rod 8 allows the fixing rod 202 and the connecting block 203 to bend.

[0031] See also Figure 5 Two mounting blocks 16 are fixedly mounted on the outer wall of the fixed plate 201 , a mounting rod 17 is fixedly connected between the two mounting blocks 16 , and the fixed rod 202 is rotatably connected to the outer wall of the mounting rod 17 .

[0032] The mounting block 16 fixes the mounting rod 17 on one side of the fixing plate 201, and one side of the fixing rod 202 can rotate along the outer wall of the mounting rod 17. Since the fixing rod 202 will tilt when bending occurs between the fixing rod 202 and the connecting block 203, in order to make the fixing plate 201 always fit with the lens 1, the mounting rod 17 can ensure that the fixing rod 202 will not affect the fixing plate 201 even if it tilts.

[0033] See also Figure 5 The fixed disk 201 is provided with a circular groove 5, a part of the heating wire 4 is located inside the circular groove 5, the outer wall of the heating wire 4 abuts against the inner wall of the fixed disk 201, and the material of the fixed disk 201 is a high temperature alloy.

[0034] The heating wire 4 is wound in the circular groove 5 so that the heating wire 4 will not fall off the fixing plate 201 easily. The fixing plate 201 is made of high temperature alloy to prevent the fixing plate 201 in direct contact with the heating wire 4 from being damaged due to the high temperature of the heating wire 4 .

[0035] See also Figure 4 The connecting block 203 is provided with through grooves 15 , and the fixing ring 204 is located between the plurality of through grooves 15 , and the through grooves 15 are slidably connected to the outer wall of the fixing ring 204 .

[0036] The through groove 15 provides space for the connecting block 203 to be sleeved on the outer wall of the fixing ring 204, so that the connecting block 203 can rotate along the outer wall of the fixing ring 204. Since the distance between each corner of the lens 1 and the fixing ring 204 is different, the angle of each connecting block 203 along the outer wall of the fixing ring 204 is also different. The rotatable connection between the connecting block 203 and the fixing ring 204 allows the connecting block 203 to adjust its own angle, which is convenient for adapting to the adjustment of the heating wire 4 by the fixing rod 202 and the fixing disk 201.

[0037] See also Figure 3-Figure 4 A fixing block 9 is fixedly installed on the inner wall of the fixing ring 204 , a connecting rod 6 is fixedly installed on the outer wall of the fixing block 9 , and the telescopic end of the cylinder 205 is connected to an end of the connecting rod 6 away from the fixing block 9 .

[0038] The cylinder 205 drives the connecting rod 6 to drive the fixing ring 204 to move through the fixing block 9. The connection between the fixing block 9 and the fixing ring 204 prevents the fixing block 9 from affecting the rotation of the connecting block 203.

[0039] See also Figure 3 A plurality of supporting rods 13 are installed on the outer wall of the connecting rod 6, a connecting rope 12 is wrapped around the outer wall of the supporting rod 13, one end of the connecting rope 12 is connected to the outer wall of the connecting block 203, and a limiting plate 14 is installed on one end of the supporting rod 13.

[0040] Pull the connecting rope 12 to wrap around the outer wall of the support rod 13. As the connecting rope 12 is gradually pulled, the distance between the connecting block 203 and the connecting rod 6 can be adjusted. Pulling the connecting block 203 can drive the fixing rod 202 to move together, so that the fixing rod 202 drives the fixing plate 201 to move toward the direction of the connecting rod 6. This can achieve the ability to separately adjust the distance between the fixing plate 201 and the middle of the lens 1 according to the different lengths of each corner of the lens 1, which is suitable for some lenses 1 with irregular shapes.

[0041] See also Figure 3-Figure 4 A circular fixing plate 10 is fixedly mounted on the outer wall of the fixing block 9 , and a spring 11 is connected between the outer wall of the circular fixing plate 10 and the outer wall of the connecting block 203 .

[0042] The circular fixing plate 10 is connected to the connecting block 203 by a spring 11. After the connecting rope 12 is pulled to move the connecting block 203 upward, if it is necessary to move the connecting block 203 downward toward the circular fixing plate 10, just loosen the connecting spring 11 between the connecting rope 12 and the support rod 13 to automatically pull the connecting block 203 backward without manually pressing the connecting block 203.

[0043] Working principle:

[0044] The heating wire 4 does not directly contact the surface of the lens 1, so as to avoid the high-temperature heating wire 4 directly contacting the lens 1 and causing damage or deformation of the lens 1. The cylinder 205 drives the fixing ring 204 to move, and the fixing ring 204 drives the connecting block 203 and the fixing rod 202 to move together when moving. The multiple fixing plates 201 spread the heating wire 4, so the fixing plates 201 move with the fixing rod 202 and drive the heating wire 4 to shrink inward or expand outward.

[0045] When the fixing ring 204 moves toward the inner wall of the outer shell 3, it will pull the multiple fixing plates 201 to gather toward the middle of the lens 1, and then make the heating wire 4 move toward the middle of the lens 1. When the fixing ring 204 moves toward the direction of the lens 1, it will push the multiple fixing plates 201 to expand outwards, and then make the heating wire 4 expand outwards, thereby increasing the heating area of ​​the heating wire 4 and making the lens 1 heated more evenly.

[0046] Pull the connecting rope 12 to wrap around the outer wall of the support rod 13. As the connecting rope 12 is gradually pulled, the distance between the connecting block 203 and the connecting rod 6 can be adjusted. Pulling the connecting block 203 can drive the fixing rod 202 to move together, so that the fixing rod 202 drives the fixing plate 201 to move toward the direction of the connecting rod 6. This can achieve the ability to separately adjust the distance between the fixing plate 201 and the middle of the lens 1 according to the different lengths of each corner of the lens 1, which is suitable for some lenses 1 with irregular shapes.
