In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In the related technology, when an automobile manufacturer needs to switch suppliers (such as switching from a supplier at point A to a supplier at point B), complex fixed structure changes are often required due to the differences in shape and fixed structure between the old and new sensors. This not only increases the design and production difficulty of the automobile manufacturer and prolongs the change cycle, but also requires additional funds to be invested in fixed structure changes and adaptations, thereby increasing production costs. Figure 1-Figure 3 Three different types of rain sensors in the related art are presented.

[0042] Reference below Figure 4-Figure 10 A rain sensor fixing structure 2 according to an embodiment of the present utility model is described.

[0043] like Figure 4-Figure 10 As shown, according to the utility model, the rain sensor fixing structure 2 is used for a vehicle, and the rain sensor fixing structure 2 includes a main frame 21, a first clamping portion 22 and a second clamping portion 23. The main frame 21 is formed with a receiving groove for accommodating the rain sensor 1, and the main frame 21 has a symmetry axis and a symmetry center; the first clamping portion 22 is symmetrically arranged on the periphery of the main frame 21 about the symmetry axis; the second clamping portion 23 is symmetrically arranged on the periphery of the main frame 21 about the symmetry center; wherein the angle between the first clamping portion 22 and the second clamping portion 23 and the line connecting the symmetry center is α and satisfies: 0°<α≤50°.

[0044] According to the rain sensor fixing structure 2 of the utility model, the receiving groove of the main frame 21 is used to accommodate the rain sensor 1, so that the main body 11 of the rain sensor 1 can be embedded in the receiving groove to achieve stable fixing and installation of the rain sensor 1 on the vehicle. The main frame 21 has a symmetry axis and a symmetry center, which ensures the mechanical balance of the rain sensor fixing structure 2 and enhances the overall stability. Moreover, due to the symmetric structure, it is easy to find the correct installation position, which reduces the possibility of installation errors and improves the installation efficiency. By providing a first clamping portion 22, the first clamping portion 22 is symmetrically arranged on the outer periphery of the main frame 21 about the symmetry axis, so that the first clamping portion 22 can be connected with the main frame 21 as shown in FIG. Figure 1 The first type of rain sensor 1 in the related art shown in the figure is fixed by snapping. By setting the second snap-fitting portion 23, the second snap-fitting portion 23 is symmetrically arranged on the outer periphery of the main frame 21 about the symmetry center, so that the second snap-fitting portion 23 can be fixed with the second snap-fitting portion 23 as shown in the figure. Figure 2 The second type of rain sensor 1 in the related art shown is fixed by snap-fitting.

[0045] Specifically, the first clamping portion 22 and the second clamping portion 23 are suitable for clamping and fixing with different types of rain sensors 1, respectively, so that the main body 11 of the rain sensor 1 is stably embedded in the receiving groove. Figure 8 The relative position relationship between the first clamping portion 22 and the second clamping portion 23 is shown. Fig. 9 and Fig.10The cross-sectional views of the rain sensor fixing structure 2 at the positions of the first clamping portion 22 and the second clamping portion 23 are respectively shown. The angle α is the angle between two connecting lines, one of which is from the symmetry center to the first first clamping portion 22 (or the second clamping portion 23), and the other is from the symmetry center to the second first clamping portion 22 (or the second clamping portion 23), and the first first clamping portion 22 (or the second clamping portion 23) is adjacent to the second first clamping portion 22 (or the second clamping portion 23). The range of angle α is 0° to 50°, but does not include 0° (that is, α must be greater than 0°). The range of angle α is determined based on the needs in practical applications to ensure that the rain sensor fixing structure 2 is compatible with rain sensors 1 of different shapes and is easy to install and disassemble.

[0046] Therefore, according to the rain sensor fixing structure 2 of the present invention, different types of rain sensors 1 can be adapted, while ensuring the stability and convenience of installation.

[0047] It should be noted that if Figure 1 The first type of rain sensor 1 shown is similar to Figure 3 Compared with the third type of rain sensor 1 shown, Figure 1 The first type of rain sensor 1 shown is suitable for engaging with the first engaging portion 22. Figure 3 The third type of rain sensor 1 shown is suitable for being engaged with the second engaging portion 23, so the rain sensor fixing structure 2 according to the utility model can simultaneously meet the installation requirements of the first type of rain sensor 1 and the third type of rain sensor 1, such as Figure 5 and Figure 7 shown.

[0048] According to some embodiments of the present invention, Figure 4As shown, the main frame 21 includes a first arc segment 211 and a second arc segment 212, the first arc segment 211 and the second arc segment 212 are symmetrically arranged about the symmetry axis, the first clamping portion 22 and the second clamping portion 23 are respectively arranged on the first arc segment 211 and the second arc segment 212, and a receiving groove is formed between the first arc segment 211 and the second arc segment 212. The first arc segment 211 and the second arc segment 212 are used to match the arc edge of the main body 11 of the rain sensor 1, and can achieve a close fit with the rain sensor 1 to provide support and fixing. The first arc segment 211 and the second arc segment 212 are symmetrically arranged about the symmetry axis, which not only improves the stability of the structure, but also makes the installation process simpler and more intuitive, reducing the difficulty of installation. When the main body 11 of the rain sensor 1 is engaged with the first clamping portion 22 or the second clamping portion 23 respectively provided on the first arc segment 211 and the second arc segment 212, the main body 11 of the rain sensor 1 will be embedded in the receiving groove between the first arc segment 211 and the second arc segment 212, thereby achieving a stable fixing effect.

[0049] According to some embodiments of the present invention, Figure 4 As shown, at least one of the first arc segment 211 and the second arc segment 212 is formed with an avoidance groove 21a, and the avoidance groove 21a is arranged on the end surface of the first arc segment 211 and the second arc segment 212 in the thickness direction and is adjacent to the receiving groove. The avoidance groove 21a is formed on one of the first arc segment 211 and the second arc segment 212, or the avoidance groove 21a is formed on both the first arc segment 211 and the second arc segment 212. The avoidance groove 21a is arranged on the end surface of the first arc segment 211 and the second arc segment 212 in the thickness direction and is adjacent to the receiving groove, so that the avoidance groove 21a can avoid the protrusion formed on the edge of the main body 11 of the rain sensor 1, so as to realize that the rain sensor fixing structure 2 can be compatible with more types of rain sensors 1, thereby improving versatility.

[0050] Specifically, in Figure 3 In the third type of rain sensor 1 in the related art shown, a protrusion is formed on the edge of the main body 11. When the rain sensor 1 is installed, the protrusion on the edge of the main body 11 can be smoothly embedded in the avoidance groove 21a, thereby avoiding interference with the fixing structure and facilitating the installation positioning and limiting of the rain sensor 1, so that the rain sensor fixing structure 2 can effectively communicate with, for example, Figure 3 The third type of rain sensor 1 in the related art is fixed in cooperation.

[0051] It should be noted that if Figure 1 The first type of rain sensor 1 shown is similar to Figure 2 Compared with the second type of rain sensor 1 shown, Figure 1The first type of rain sensor 1 shown is similar to Figure 2 The second type of rain sensors 1 shown are all suitable for engaging with the first engaging portion 22. Figure 2 The second type of rain sensor 1 shown has a protruding portion formed on the edge of the main body 11. Therefore, by providing the avoidance groove 21a, the rain sensor fixing structure 2 can simultaneously meet the installation requirements of the first type of rain sensor 1 and the second type of rain sensor 1. Figure 5 and Figure 6 shown.

[0052] According to some embodiments of the present invention, Figure 4 As shown, the avoidance grooves 21a are constructed to be spaced apart in the circumferential direction of the first arc segment 211 and the second arc segment 212 and are symmetrically arranged about the symmetry center. The first arc segment 211 and the second arc segment 212 are both formed with avoidance grooves 21a, and there are multiple avoidance grooves 21a, and there are intervals between the multiple avoidance grooves 21a in the circumferential direction to meet specific installation requirements. The avoidance grooves 21a are symmetrically arranged about the symmetry center. If starting from a symmetry center, the avoidance grooves 21a are symmetrically distributed on both sides, which helps to balance the force, enhance the structural stability and facilitate installation.

[0053] According to some embodiments of the present invention, Figure 4 As shown, the main frame 21 also includes a connecting frame 213, which is connected to the first arc segment 211 and the second arc segment 212 respectively and extends in the extension direction of the symmetry axis, so that the connecting frame 213 can be fixed with the first extension portion of the rain sensor 1 on one side of the extension direction of the symmetry axis in the related art. A receiving groove connected to the receiving groove is formed on the connecting frame 213. After the main body 11 of the rain sensor 1 is fixed with the first clamping portion 22 or the second clamping portion 23, the first extension portion of the rain sensor 1 will be embedded in the receiving groove, thereby further enhancing the stability and firmness of the rain sensor 1 on the main frame 21.

[0054] According to some embodiments of the present invention, for example Figure 4 As shown, the main frame 21 also includes an extension frame 214, which is respectively connected to the first arc segment 211 and the second arc segment 212 and extends along the direction of the symmetry axis in a direction away from the connecting frame 213, so that the extension frame 214 can be fixedly matched with the second extension portion of the rain sensor 1 on the other side of the extension direction of the symmetry axis in the related art, thereby providing support and fixation for the other side of the rain sensor 1 on the main frame 21.

[0055] According to some embodiments of the present invention, Figure 4As shown, a connecting plate 215 is connected between the first arc segment 211 and the second arc segment 212, and a through groove is formed between the connecting plate 215 and the first arc segment 211 and the second arc segment 212. The connecting plate 215 is used to support the first extension portion 12 or the second extension portion 13 of the rain sensor 1, so as to achieve stable installation of the rain sensor 1 on the main frame 21. After the main body 11 of the rain sensor 1 is fixed with the first clamping portion 22 or the second clamping portion 23 by clamping, the first extension portion or the second extension portion will be supported on the connecting plate 215 and at least partially embedded in the through groove to pass through the connecting plate 215, thereby further enhancing the stability and fixing effect of the rain sensor 1 on the main frame 21.

[0056] According to some embodiments of the present invention, Figure 4 As shown, the rain sensor fixing structure 2 also includes a protective ring 24, which is arranged on the main frame 21 and defines a protective space between the protective ring 24 and the main frame 21, and the first clamping portion 22 and the second clamping portion 23 are respectively located in the protective space. By providing the protective ring 24, the protective ring 24 is arranged on the main frame 21 to protect the portion in the protective space between the protective ring 24 and the main frame 21. Specifically, the first clamping portion 22 and the second clamping portion 23 are respectively located in the protective space, and the protective ring 24 can prevent external impact from acting on the first clamping portion 22 and the second clamping portion 23, thereby enhancing the stability and durability of the first clamping portion 22 and the second clamping portion 23, and realizing the safe fixation of the rain sensor 1 on the main frame 21.
