[0032] The following will describe the implementation methods of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.
[0033] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.
[0034] See also Figures 1 to 3 An embodiment of the present application provides a protection component for a radar, wherein the radar 10 has a window, and the protection component includes a first protection member 100 made of a soft material and a second protection member 200 made of a hard material, wherein the first protection member 100 is arranged on at least two surfaces of an edge of the window 12, and the second protection member 200 is arranged on the outside of the first protection member 100; wherein the first protection member 100 is arranged at least on the edge of the front side of the window 12.
[0035] In this embodiment, a soft first protective member 100 is provided on at least two surfaces of the window 12 to wrap the periphery of the window 12 and enhance the buffering performance of the window 12; at the same time, a hard second protective member 200 is provided on the outer side of the first protective member 100 to enhance the hardness of the periphery of the window 12 through the second protective member 200. When foreign objects from the outside hit the periphery of the window 12, the second protective member 200 can improve the impact resistance of the window 12 against foreign objects from the outside, and at the same time, the first protective member 100 can improve the buffering of the periphery of the window 12 against the impact force from the outside, thereby avoiding the problem that the window 12 is damaged or broken due to the impact of foreign objects such as gravel, resulting in the failure of the radar 10, thereby extending the service life of the radar 10 and improving the performance of the radar 10.
[0036] In addition, the protection component provided in this embodiment can be applied to the window 12 of the embedded radar device at the front end of the vehicle, and can also be applied to various other devices involving edge protection of the window 12, such as cameras, display devices, etc.
[0037] Specifically, the protection component is configured as a combined component including at least a first protection member 100 and a second protection member 200. The first protection member 100 may be a square structure member with a first window. The first window may be a rectangular window or a avoidance window of other shapes to expose the window 12. The second protection member 200 may be a square structure member with a second window. The size of the second window may be comparable to that of the first window or slightly larger than that of the first window to expose the window 12 and avoid blocking the field of view of the radar 10. For example, when the window 12 is square, the protection component may cover and wrap around the front edge, the peripheral side and / or the rear edge of the window 12 to protect the periphery of the window 12. At the same time, four positive corners may be formed at the four corners of the window 12 to enhance the rigidity and strength of the four corners of the window 12 and protect the four corners of the window 12. It is understandable that the width of the first protective member 100 and the second protective member 200 on the front edge of the window 12 needs to be adjusted according to the size of the black border of the radar window 12, and the width limit value cannot block the field of view of the radar 10. For example, but not limited to, the field of view of the radar 10 can be 120°.
[0038] In one example, the second protective member 200 may be made of stainless steel, and in this case, the first protective member 100 may be an adhesive layer filled between the second protective member 200 and the window 12. In this way, the hard second protective member 200 can improve the hardness and rigidity at the edge of the window 12, at least improve the impact resistance at the edge of the window 12; the first protective member 100 can also realize the connection and fastening between the second protective member 200 and the window 12, and at the same time, the first protective member 100 can also improve the buffering performance at the edge of the window 12 and improve the buffering force at the edge of the window 12. In addition, the soft first protective member 100 can also prevent the hard second protective member 200 from directly contacting the window 12, causing friction, scratches, damage, etc. to the window 12, and further enhance the protective performance of the protective component to the window 12.
[0039] Of course, in other embodiments, the first protective member 100 may also be any one of rubber, silicone, silicone rubber or high temperature foam, which requires an independent mold to be separately formed. The second protective member 200 may also be any one of other metal parts, plastic parts or sheet metal parts, which requires another mold to be separately formed. The first protective member 100 and the second protective member 200 may be connected and fastened by adhesive or the like, and the first protective member 100 and the window 12 may be connected and fastened by adhesive.
[0040] In a possible implementation, the wall thickness of the second protective member 200 is greater than or equal to the wall thickness of the first protective member 100. In this way, the overall hardness and rigidity of the protective component can be improved by the thicker second protective member 200, thereby increasing the thickness of the protective component wrapping the periphery of the window 12 and enhancing the impact resistance of the periphery of the window 12. For example, but not limited to, the wall thickness of the second protective member 200 is greater than the wall thickness of the first protective member 100.
[0041] See also Figure 2 In a possible embodiment, the first protective member 100 includes a first protective portion 110 and a second protective portion 120 that are connected to each other, the first protective portion 110 extends along the plane where the window 12 is located, and the second protective portion 120 extends along the thickness direction Z of the window 12. The first protective portion 110 is arranged on the edge of the front side of the window 12, and the second protective portion 120 is arranged on the outer periphery of the window 12.
[0042] In this embodiment, the first protection member 100 is configured as a combined component including at least a first protection portion 110 and a second protection portion 120. The first protection portion 110 may be an annular plate-shaped member with a first window, which is arranged on the front edge of the window 12; the second protection portion 120 may be an annular plate-shaped folded edge vertically arranged on the outer periphery of the first protection portion 110, which is arranged on the outer side of the peripheral side wall of the window 12. That is to say, in the thickness direction Z of the window 12, the cross-sectional shape of the first protection member 100 may be an inverted L-shaped structure. In this way, the window 12 is protected at least on the front edge and the peripheral side wall of the window 12, thereby improving the buffering property of the window 12 at least on its front side and the peripheral side wall; at the same time, the processing of the first protection member 100 can be facilitated, and the production cost can be reduced.
[0043] At the same time, the second protection member 200 is configured as a composite member including at least a fourth protection portion 210 and a fifth protection portion 220. The fourth protection portion 210 may be an annular plate-shaped member with a second window, which is arranged on the front side of the first protection portion 110; the fifth protection portion 220 may be an annular plate-shaped folded edge vertically arranged on the outer periphery of the second protection portion 120, which is arranged on the outer side of the peripheral side wall of the first protection member 100. That is to say, in the thickness direction Z of the window 12, the cross-sectional shape of the second protection member 200 may be an inverted L-shaped structure. In this way, the overall hardness and rigidity of the protection assembly are improved at least on the front side edge and the peripheral side wall of the first protection member 100, thereby improving the impact resistance of the window 12 at least on the front side and the peripheral side wall of the first protection member 100; at the same time, the processing of the second protection member 200 can be facilitated, and the production cost can be reduced.
[0044] See also Figure 1In a possible embodiment, the first protective member 100 also includes a third protective portion 130, which is connected to a side of the second protective portion 120 away from the first protective portion 110 and extends in the same direction as the first protective portion 110, and the third protective portion 130 is arranged on the edge of the rear side of the window 12.
[0045] In this embodiment, the first protection member 100 is configured as a composite member including at least a first protection portion 110, a second protection portion 120 and a third protection portion 130. The third protection portion 130 may be an annular plate-shaped member with a first window, which is configured on the rear edge of the window 12. That is to say, in the thickness direction Z of the window 12, the cross-sectional shape of the first protection member 100 may be a C-shaped structure. In this way, the window 12 is protected at least on the front edge, peripheral side wall and rear edge of the window 12, and the edge of the window 12 is fully wrapped, thereby improving the buffering property of the window 12 at least on its front side, peripheral side wall and rear side, and improving the buffering performance of the protection component.
[0046] At the same time, the second protection member 200 is configured as a composite member including at least a fourth protection portion 210, a fifth protection portion 220 and a sixth protection portion 230. The sixth protection portion 230 may be an annular plate-shaped member with a second window, which is configured on the rear side of the third protection portion 130. That is to say, in the thickness direction Z of the window 12, the cross-sectional shape of the second protection member 200 may be a C-shaped structure. In this way, the overall hardness and rigidity of the protection component are improved at least on the front edge, peripheral side wall and rear edge of the first protection member 100, thereby improving the impact resistance of the window 12 at least on the front side, peripheral side wall and rear side of the first protection member 100, improving the hardness and rigidity of the protection component, and improving the impact resistance of the edge of the window 12.
[0047] In a possible implementation, the length of the third protection portion 130 is less than or equal to the length of the first protection portion 110. In this way, at least raw materials for the third protection portion 130 can be saved, and the production cost of the first protection member 100 can be reduced. Of course, in other embodiments, the length of the third protection portion 130 can be equal to the length of the first protection portion 110 to facilitate processing and ensure that the force on the front and rear sides of the window 12 is balanced.
[0048] In one example, the length of the sixth protection portion 230 is less than or equal to the length of the fourth protection portion 210. In this way, at least the raw materials on the sixth protection portion 230 are saved, and the production cost of the second protection member 200 is reduced. Of course, in other embodiments, the length of the sixth protection portion 230 can be equal to the length of the fourth protection portion 210 to facilitate processing and ensure that the forces on the front and rear sides of the first protection member 100 and the window 12 are balanced. It can be understood that the length of the fourth protection portion 210 can be equivalent to the length of the first protection portion 110 to facilitate processing; or the length of the fourth protection portion 210 is slightly smaller than the length of the first protection portion 110 to avoid blocking the field of view of the radar 10. The length of the sixth protection portion 230 can be equivalent to the length of the third protection portion 130 to facilitate processing; or the length of the sixth protection portion 230 is slightly smaller than the length of the third protection portion 130 to avoid blocking the field of view of the radar 10.
[0049] See also Figure 3 In a possible embodiment, the first protective member 100 includes a first protective portion 110 and a third protective portion 130 that are arranged in parallel and at intervals. The first protective portion 110 and the third protective portion 130 both extend along the plane where the window 12 is located. The first protective portion 110 is arranged on the edge of the front side of the window 12, and the third protective portion 130 is arranged on the edge of the rear side of the window 12.
[0050] In this embodiment, the first protection member 100 is configured as a composite member including at least a first protection portion 110 and a third protection portion 130. The first protection portion 110 may be an annular plate-shaped member with a first window, which is arranged on the front edge of the window 12; the third protection portion 130 may be an annular plate-shaped member with a first window, which is arranged on the rear edge of the window 12. That is to say, in the thickness direction Z of the window 12, the cross-sectional shape of the first protection member 100 may be a two-shaped structure. In this way, the window 12 is protected at least on the front edge and the rear edge of the window 12, thereby improving the buffering property of the window 12 at least on its front and rear sides; at the same time, the first protection portion 110 and the third protection portion 130 can be prepared using the same mold to reduce production costs.
[0051] At this time, the second protective member 200 can be configured as a combined component including at least a fourth protective portion 210 and a sixth protective portion 230, which is a two-shaped structure in the thickness direction Z of the window 12, so as to at least wrap the first protective member 100, thereby improving the overall hardness and rigidity of the protective component at least on the front and rear edges of the first protective member 100, and further improving the impact resistance of the window 12 at least on the front and rear sides of the first protective member 100, improving the hardness and rigidity of the protective component, and improving the impact resistance of the edge of the window 12.
[0052] Alternatively, the second protective member 200 can also be configured as a composite component including at least a fourth protective portion 210, a fifth protective portion 220 and a sixth protective portion 230, which is a C-shaped structure in the thickness direction Z of the window 12. In this way, the overall hardness and rigidity of the protective component are improved at least on the front edge, peripheral side wall and rear edge of the first protective member 100, thereby improving the impact resistance of the window 12 at least on the front side, peripheral side wall and rear side of the first protective member 100, improving the hardness and rigidity of the protective component, and improving the impact resistance of the edge of the window 12.
[0053] See also Figure 3 In a possible implementation, the first protection portion 110 is provided with a first inclined surface 111, the first inclined surface 111 is located inside the first protection portion 110, and the first inclined surface 111 gradually expands in the direction from the rear side to the front side of the window 12; and / or, the third protection portion 130 is provided with a second inclined surface 131, the second inclined surface 131 is located inside the third protection portion 130, and the second inclined surface 131 gradually expands in the direction from the front side to the rear side of the window 12. In this way, inclined surfaces are provided on the first protection portion 110 and the third protection portion 130 to prevent the first protection member 100 from blocking the field of view angle used for detection by the radar 10, thereby ensuring the operational sensitivity and reliability of the radar 10.
[0054] In one example, the fourth protection part 210 is provided with a third slope 211, the third slope 211 is located inside the fourth protection part 210, and the third slope 211 gradually expands in the direction from the rear side to the front side of the window 12; and / or, the sixth protection part 230 is provided with a fourth slope 231, the fourth slope 231 is located inside the sixth protection part 230, and the fourth slope 231 gradually expands in the direction from the front side to the rear side of the window 12.

[0055] In a possible implementation, the wall thickness of the first protection portion 110 decreases from the outside to the inside of the first protection portion 110; and / or the wall thickness of the third protection portion 130 decreases from the outside to the inside of the third protection portion 130. The thickness of the first protection portion 110 and / or the thickness of the third protection portion 130 is configured non-uniformly, so that the outer edge is thick and the middle is thin, so that the impact resistance of the edge of the window 12 can be improved, and the field of view of the radar 10 can be prevented from being blocked.
[0056] In one example, the wall thickness of the fourth protection portion 210 decreases from the outside to the inside of the fourth protection portion 210; and / or the wall thickness of the sixth protection portion 230 decreases from the outside to the inside of the sixth protection portion 230. The thickness of the fourth protection portion 210 and / or the thickness of the sixth protection portion 230 is configured non-uniformly, so that the outer edge is thick and the middle is thin, so that the impact resistance of the edge of the window 12 can be improved, and the field of view of the radar 10 can be prevented from being blocked.
[0057] In one example, the thickness of the window 12 can also be configured unevenly, so that it is thin at the edges and thick in the middle.
