[0028] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely exemplary of specific ways to implement and use the present invention, and are not intended to limit the scope of the present invention. When describing the structural positions of the various components, such as up, down, top, bottom, etc., the expressions of directions are not absolute, but relative. When the various components are arranged as shown in the figure, these directional expressions are appropriate, but when the positions of the various components in the figure change, these directional expressions also change accordingly.

[0029] In this document, unless otherwise clearly specified and limited, the terms "installation", "assembly", "connection", "fixation" and the like 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 an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in this document can be understood according to the specific circumstances.

[0030] Since the sunlight sensor senses the sunlight intensity through an optical element, the optical element usually needs to be installed in front of the vehicle and facing the outside of the vehicle, otherwise the sunlight intensity sensed by the sunlight sensor will be lower than the actual value, resulting in sunlight signal collection errors. Therefore, the sunlight sensor needs to be fixed during the assembly process. The inventor found that the fixing structure of the sunlight sensor of the current vehicle is relatively complex, which makes the installation and removal of the sunlight sensor take a long time.

[0031] Reference Figures 1 to 4 , Figure 1 A schematic diagram showing a dashboard according to an embodiment of the present invention is shown. Figure 2 Shows Figure 1 A partial enlarged view of a dashboard of FIG. 1 and showing a first fixing member of a fixing device for a vehicle-mounted sensor according to an embodiment of the present invention, Figure 3 A rear view showing a second fixing member of a fixing device for a vehicle-mounted sensor according to an embodiment of the present invention, and Figure 4 Shows Figure 3 A side view of a second fixing member.

[0032] The vehicle component according to the present invention is provided with a fixing device 130 for the vehicle-mounted sensor 120, and the fixing device 130 is used to fix the vehicle-mounted sensor 120 to the vehicle. In this embodiment, the vehicle-mounted sensor 120 may be a sunlight sensor, and the vehicle component may be Figure 1 In the dashboard 100 shown in FIG. 1 , the fixing device 130 is disposed between two air conditioning outlets 110 of the dashboard 100. Figure 1 As shown in , the air conditioning outlet 110 may be an outlet facing upwards and adjacent to the front windshield. The fixing device 130 includes a first fixing member 133 and a second fixing member 131. In this embodiment, the first fixing member 133 is disposed on the instrument panel 100, and the second fixing member 131 is shown as Figure 3 The first fixing member 133 has a mounting opening 140 for mounting the vehicle-mounted sensor 120, and the circumferential edge of the second fixing member 131 matches the circumferential edge of the first fixing member 133 and the second fixing member 131 can cover the mounting opening 140 of the first fixing member 133. The second fixing member 131 is provided with a through hole 132, and the size of the through hole 132 matches the circumferential size of the vehicle-mounted sensor 120, that is, the vehicle-mounted sensor 120 can pass through the through hole 132 of the second fixing member 131 to fix the vehicle-mounted sensor 120 as a whole. In addition, the first fixing member 133 is provided with a clamping portion 134, which is suitable for clamping the wiring harness 121 of the vehicle-mounted sensor 120 to pre-fix the vehicle-mounted sensor 120.

[0033] In this way, the vehicle-mounted sensor 120 is prevented from falling into the dashboard 100 when the dashboard 100 is rotated 180°, thereby preventing subsequent installation difficulties. The first fixing member 133 and the second fixing member 131 of the fixing device 130 cooperate with each other and are integrated into the dashboard 100 of the vehicle, making the design of the fixing device 130 and the dashboard 100 more compact. Even when the space on the dashboard 100 is very limited, the vehicle-mounted sensor 120 can be fixed and pre-fixed.

[0034] like Figure 2As shown, the first fixing member 133 may be provided with a sink 136. In some embodiments, the sink 136 and the second fixing member 131 may be arched, so that the space between the air-conditioning outlet 110 of the instrument panel 100 can be fully utilized. It is understandable that the sink 136 can also be designed into other shapes according to needs, such as round, square, etc. The sink 136 can extend toward the installation opening 140, that is, the sink 136 forms the side wall of the installation opening 140 and a part of the bottom of the sink 136 is through, so that the vehicle-mounted sensor 120 passes through. The clamping portion 134 is arranged at the bottom of the sink 136, specifically, the clamping portion 134 is arranged on the side wall of the installation opening 140. In this way, the second fixing member 131 can abut against the sinker 136, and after the second fixing member 131 abuts against the sinker 136, the space occupied by the dashboard 100 is not increased, so that the design of the dashboard 100 is more compact, and the pre-fixing and fixing functions of the vehicle-mounted sensor 120 are integrated on the sinker 136 of the dashboard 100.

[0035] Continue to refer to Figure 2 The clamping portion 134 can be configured as an opening that communicates with the mounting opening 140 via the clamping opening 135, that is, the clamping portion 134 can communicate with the mounting opening 140 via the clamping opening 135. In this way, the space occupied by the first fixing member 133 on the instrument panel 100 is further reduced, making the design of the fixing device 130 and the instrument panel 100 more compact.

[0036] In some embodiments, the size of the clamping opening 135 may be smaller than the outer diameter of the harness 121 of the vehicle-mounted sensor 120. For example, the size of the clamping opening 135 may be 1 mm smaller than the outer diameter of the harness 121 of the vehicle-mounted sensor 120. In this case, when the outer diameter of the harness 121 of the vehicle-mounted sensor 120 is 3.8 mm, the size of the clamping opening 135 may be 2.8 mm to pre-fix the vehicle-mounted sensor 120.

[0037] In some embodiments, the second fixing member 131 may be provided with a plurality of buckles 137 adjacent to its periphery. Figure 3 As shown in FIG. 1 , three buckles 137 are shown. Figure 3 In the position shown, one of the three buckles 137 is arranged at the top of the arched second fixing member 131, and the other two buckles are arranged at the bottom of the second fixing member 131. Figure 4 As shown, the buckle 137 extends from the inner surface of the second fixing member 131 along the Figure 4 The “inner surface” here refers to the surface facing the inside of the instrument panel 100. Figure 2The sinking platform 136 is provided with a joint portion 138 that matches with the buckle 137, and the joint portion 138 is provided on the side wall of the installation opening 140. In this way, the second fixing member 131 can be snapped to the sinking platform 136, which increases the fixing strength between the second fixing member 131 and the sinking platform 136, and through the snap connection, the second fixing member 131 is easy to be disassembled from the sinking platform 136.

[0038] In some embodiments, the clamping portion 134 can be arranged adjacent to one of the plurality of engaging portions 138. Figure 2 In the illustrated position, the clamping portion 134 is disposed below the joint portion located at the top of the sinking platform 136 among the three joint portions 138, and the clamping opening 135 of the clamping portion 134 is communicated with the joint portion 138. In this way, the structure of the clamping portion 134 and the sinking platform 136 disposed on the instrument panel 100 can be made more compact, the space occupied by the clamping portion 134 is reduced, the complexity of the structure of the instrument panel 100 is further reduced, the disassembly and assembly of the vehicle-mounted sensor 120 is facilitated, and the manufacturing cost is reduced.

[0039] Reference Figure 5 to Figure 6 , Figure 5 A schematic diagram showing a wiring harness of a vehicle-mounted sensor fixed to a dashboard according to an embodiment of the present invention, and Figure 6 A schematic diagram showing a vehicle-mounted sensor fixed to a dashboard by a fixing device according to an embodiment of the present invention is shown.

[0040] When the vehicle-mounted sensor 120 is installed on the dashboard 100 along with the air-conditioning box, the wiring harness 121 of the vehicle-mounted sensor 120 can be first clamped to the clamping portion 134 of the first fixing member 133 provided on the dashboard 100, and the vehicle-mounted sensor 120 can be pre-fixed to prevent the vehicle-mounted sensor 120 from falling into the dashboard 100 when the dashboard 100 is rotated 180°, thereby causing difficulties in subsequent installation. Then, according to the assembly process of the dashboard 100, after the dashboard 100 is rotated 180°, the pre-fixed vehicle-mounted sensor 120 and its wiring harness 121 are taken out from the clamping portion 134 through the clamping port 135. Then, the upper cover 122 of the vehicle-mounted sensor 120 is moved from the rear of the second fixing member 131 (the "rear" here refers to the rear with respect to the second fixing member 131). Figure 6 The second fixing member 131 shown on the opposite side of the surface) passes through the through hole 132, and the flange 124 ( Figure 8 ) is fixed to the recess 139 (shown in FIG. Figure 3 Finally, the second fixing member 131 is abutted against the first fixing member 133 and the buckle 137 of the second fixing member 131 is clamped to the joint portion 138 of the sink 136, so as to fix the vehicle-mounted sensor 120 to the instrument panel 100.

[0041] Reference Figure 7, Figure 7 Shown along Figure 6 Cross-section diagram along line AA.

[0042] In some embodiments, the size of the engagement portion 138 (eg Figure 2 The dimension d1 shown in FIG. 1 may be larger than the dimension of the buckle 137 (eg Figure 3 d2) and is smaller than the circumferential dimension of the onboard sensor 120 (e.g. Figure 7 The outer diameter d3 shown in FIG. Figure 2 , Figure 3 and Figure 7 When the size d1 of the buckle 137 is 4 mm and the outer diameter d3 of the vehicle-mounted sensor 120 is 12 mm, the size d1 of the coupling portion 138 matching the buckle 137 can be 5 mm to ensure the clamping connection between the buckle 137 and the coupling portion 138 and the pre-fixation of the vehicle-mounted sensor 120.

In some embodiments, the upper cover 122 may be provided with a snap-on recess or flange ( Figure 8 In addition, the second fixing member 131 of the fixing device 130 may be provided with a snap-fitting protrusion or recess ( Figure 3 The recess 139 is shown in the figure to further increase the fixing strength between the vehicle-mounted sensor 120 and the second fixing member 131.
