Description

Technical Field

[0001] This utility model relates to a protective structure, and more particularly to a protective structure for a radar device. Background Technology

[0002] In recent years, efforts to provide access to sustainable transportation systems that also take into account vulnerable groups such as the elderly, disabled, and children among transportation participants have become increasingly active. To achieve this goal, research and development efforts are focused on further improving the safety and convenience of transportation through developments related to enhancing safety. However, in developments related to improving safety, the rigidity and waterproofing of the mounting structure for devices such as radar units remain challenges.

[0003] In existing technology, a radar device can be installed on the inner side of the front bumper panel of a vehicle. The radar device emits radio waves outwards (e.g., towards the front) to detect environmental parameters and even long-range targets, providing a basis for autonomous driving. However, if the radar device is exposed to water, its dielectric constant changes, making it unable to detect targets in rainy weather. Therefore, as a current waterproofing measure, a waterproof membrane can be placed in the gap between the radar housing and the cover sealing the housing. However, to avoid interfering with the radar device's detection performance, a dedicated waterproof membrane is required, increasing manufacturing costs. Therefore, it is necessary to improve the radar device's protective structure to balance low cost and high waterproof performance, thereby preventing damage to the radar device and improving safety.

[0004] This invention aims to improve safety by addressing the aforementioned problems. Furthermore, it further enhances traffic safety and contributes to the development of sustainable transportation systems. Utility Model Content

[0005] This invention provides a protective structure for radar devices that balances low cost and high waterproof performance, thereby preventing damage to the radar devices and improving safety.

[0006] This utility model provides a radar device protection structure, including: a bumper panel with a through bumper opening; a reinforcing member disposed on the inner side of the bumper panel and having a radar receiving hole facing the bumper opening; a radar device disposed in the radar receiving hole; a camera device disposed on the reinforcing member; and a cover plate disposed on the outer side of the reinforcing member to close the radar receiving hole. The reinforcing member has a first fastening boss and a second fastening boss protruding inwards. The radar device is fastened to the reinforcing member via the first fastening boss, and the camera device is fastened to the reinforcing member via the second fastening boss. The first fastening boss and the second fastening boss are at the same horizontal height and extend towards each other in the horizontal direction. The extended portions of each of the first and second fastening bosses extend towards a position closer to the inner side than the radar device.

[0007] In an embodiment of this utility model, the radar device is fastened to the reinforcing member from the inside by the first fastening boss, and the camera device is fastened to the reinforcing member from the outside by the second fastening boss.

[0008] In an embodiment of this utility model, the reinforcing member further includes an eave-shaped portion that protrudes inward and connects the first fastening boss and the second fastening boss in the horizontal direction.

[0009] In an embodiment of this utility model, the eave-shaped portion extends towards the inner side relative to the radar device.

[0010] In an embodiment of the present invention, the reinforcing member is further provided with a mounting portion located at the upper edge of the radar receiving hole. The mounting portion has a top extending inward and a bent portion bending downward from the top. The first fastening boss and the second fastening boss are disposed in the bent portion, and the top gradually extends downward from the outside to the inside.

[0011] Based on the above, in the radar device protection structure of this utility model, the reinforcing member inside the bumper panel is provided with a first fastening boss and a second fastening boss protruding inward. The radar device is fastened to the reinforcing member via the first fastening boss, and the camera device is fastened to the reinforcing member via the second fastening boss. The first and second fastening bosses are located at the same horizontal height and extend horizontally, thus improving the rigidity of the mounting structure for the radar device and the camera device. Furthermore, the extended portions of the first and second fastening bosses extend further inward than the radar device, so even in wet environments such as rainy days, water can slide inward from the extended portions (e.g., to the rear) without intruding into the radar device. Therefore, the radar device protection structure of this utility model can balance low cost and high waterproof performance, thereby preventing damage to the radar device and improving safety.

Figure 7 yes Figure 5 The diagram shows a partial cross-sectional view of the radar device protection structure around the first fastening boss. The following is a related illustration. Figures 1 to 7 The present invention describes the specific structure of the radar device protection structure 100 in the embodiments of the present invention, but the present invention is not limited thereto and can be adjusted according to requirements.

[0044] Please refer to Figures 1 to 4 In this embodiment, the radar device protection structure 100 includes a bumper panel 110, a reinforcing member 120, a radar device 130, a camera device 140, and a cover plate 150. The bumper panel 110 has a through bumper opening 112. The reinforcing member 120 is disposed on the inner side (e.g., the rear side) of the bumper panel 110 and has a radar receiving hole 122 facing the bumper opening 112. The radar device 130 is disposed within the radar receiving hole 122. The camera device 140 is disposed on the reinforcing member 120. The cover plate 150 is disposed on the outer side (e.g., the front side) of the reinforcing member 120 to close the radar receiving hole 122. Furthermore, please refer to... Figures 5 to 7 The reinforcing member 120 is provided with a first fastening boss 124 and a second fastening boss 126 protruding inward (e.g., rearward). The radar device 130 is fastened to the reinforcing member 120 via the first fastening boss 124 (which is paired with the first fastening member 160). The camera device 140 is fastened to the reinforcing member 120 via the second fastening boss 126 (which is paired with the second fastening member 170). The first fastening boss 124 and the second fastening boss 126 are located at the same horizontal height and extend towards each other in the horizontal direction (i.e., they have extensions configured as ribs). Furthermore, the extensions 124a and 126a of the first fastening boss 124 and the second fastening boss 126 respectively extend towards a position further inward (e.g., rearward) than the radar device 130.

[0045] Specifically, in this embodiment, as Figures 1 to 4As shown, the bumper panel 110 is, for example, an outer plate component located on the outer side (corresponding to the front side) of a bumper beam (not shown) at the front of the vehicle, extending in the left-right direction and having an elongated bumper opening 112. The reinforcement 120 is, for example, a frame component joined to the inner side (e.g., the rear side) of the bumper panel 110 to increase rigidity (reinforcement), extending in the left-right direction and having a radar receiving hole 122 whose shape substantially corresponds to that of the radar device 130. The radar device 130 is, for example, disposed within the radar receiving hole 122 and facing the bumper opening 112. The camera device 140 is, for example, disposed on the reinforcement 120 at a location adjacent to the radar device 130. The cover plate 150 is, for example, a cover structure disposed between the bumper panel 110 and the reinforcement 120. It has a cover portion 152 whose shape generally corresponds to the radar device 130 and covers the radar receiving hole 122 from the outside (e.g., the front side). Thus, the radar device 130 disposed within the radar receiving hole 122 is also covered by the cover portion 152 of the cover plate 150. Furthermore, the radar device protection structure 100 may also include a guide plate 180 disposed on the inner side (e.g., the rear side) of the reinforcement 120. The guide plate 180 is, for example, a cover structure joined to the inner side (e.g., the rear side) of the reinforcement 120. It has a support portion 182 whose shape generally corresponds to the radar device 130 and supports the radar receiving hole 122 from the inside (e.g., the rear side). Thus, the radar device 130 disposed within the radar receiving hole 122 is also covered by the support portion 182 of the guide plate 180. However, this utility model does not limit the specific structure of the bumper panel 110, the reinforcing member 120, the radar device 130, the camera device 140, the cover plate 150, and the guide plate 180, or whether the guide plate 180 is provided or not, etc., which can be adjusted according to needs.

[0046] Therefore, in this embodiment, as Figures 5 to 7As shown, the first fastening boss 124 and the second fastening boss 126 are, for example, boss structures respectively provided on the inner side (e.g., the rear side) of the reinforcing member 120 and protruding inward (e.g., the rear side), and are located in the reinforcing member 120 at a position higher than the upper edge of the radar receiving hole 122. Furthermore, the first fastening boss 124 and the second fastening boss 126 each have fastening through holes 124b and 126b communicating with the outer side (front side) and the inner side (rear side). In this way, at least the upper bracket 132 of the radar device 130 can be fastened to the reinforcing member 120 by the first fastening boss 124 and the first fastening component 160 (e.g., a fastening bolt), and at least the upper bracket 142 of the camera device 140 can be fastened to the reinforcing member 120 by the second fastening boss 126 and the second fastening component 170 (e.g., a fastening bolt). Furthermore, the first fastening boss 124 and the second fastening boss 126 each have an extension portion 124a and an extension portion 126a extending in the horizontal direction (e.g., the left-right direction) (i.e., configured as a rib shape). The first fastening boss 124, the second fastening boss 126, and their respective extension portions 124a and 126a are all located at the same horizontal height (e.g., ...). Figure 6 As shown by the dashed line), and formed extending from the inner side (rear side) of the reinforcement 120 towards a position further inward (e.g., rear side) than the radar device 130 (as shown by the dashed line). Figure 7 The guiding structure shown in the figure.

[0047] As an example, in this embodiment, the first fastening component 160 (e.g. Figure 3 As shown, the bracket through-hole of the upper bracket 132 of the radar device 130 and the fastening through-hole 124b of the first fastening boss 124 extend from the inside (rear side) to the outside (front side), thereby... Figures 5 to 7 As shown, the radar device 130 can be fastened to the reinforcement 120 from the inside (rear side) of the reinforcement 120 via the first fastening boss 124 (which mates with the first fastening member 160). Subsequently, the body of the radar device 130 (i.e., the portion lower than the upper bracket 132) is received in the radar receiving hole 122, which is lower than the first fastening boss 124. In contrast, the second fastening member 170 (as shown in the image)... Figure 4As shown, the camera device 140 extends from the outside (front) to the inside (rear) and is inserted into the bracket through hole of the upper bracket 142 and the fastening through hole 126b of the second fastening boss 126. Thus, the camera device 140 can be fastened to the reinforcing member 120 from the outside (front) of the reinforcing member 120 through the second fastening boss 126 (in conjunction with the second fastening member 170). Subsequently, the body of the camera device 140 (i.e. the part that is lower than the upper bracket 142) is positioned adjacent to the radar device 130. Although both the first fastening boss 124 and the second fastening boss 126 protrude from the inner side (i.e., the rear side) of the reinforcing member 120 toward the inner side, the second fastening member 170 can be inserted into the second fastening boss 126 from the outside (i.e., the front side) to fasten the upper bracket 142 of the camera device 140 because the second fastening boss 126 is provided with a fastening through hole 126b connecting the outer side and the inner side.

[0048] However, in other embodiments not shown, the camera device 140 and the radar device 130 may also be disposed on the same side of the reinforcing member 120, for example, by means of a first fastening boss 124 (with a first fastening member 160) and a second fastening boss 126 (with a second fastening member 170) fastening the reinforcing member 120 from the inside (rear side). Alternatively, the second fastening boss 126 and its extension 126a may further extend from the outer side (front side) of the reinforcing member 120 outward (front side). As long as the radar device 130 and the camera device 140 are fastened by the first fastening boss 124 and the second fastening boss 126 respectively aligned in the horizontal direction, this invention is not limited thereto and can be adjusted according to requirements.

[0049] With the above configuration, in the radar device protection structure 100 of this embodiment, the reinforcing member 120 inside the bumper panel 110 is provided with a first fastening boss 124 and a second fastening boss 126 protruding inward (e.g., rearward). The radar device 130 is fastened to the reinforcing member 120 via the first fastening boss 124, and the camera device 140 is fastened to the reinforcing member 120 via the second fastening boss 126. The first fastening boss 124 and the second fastening boss 126 are located at the same horizontal height and extend horizontally, thus improving the rigidity of the mounting structure of the radar device 130 and the camera device 140. Furthermore, the extensions 124a and 126a of the first fastening boss 124 and the second fastening boss 126 extend further inward (e.g., to the rear) than the radar device 130. Therefore, even in wet environments such as rainy days, water can slide inward (e.g., to the rear) from the extensions 124a and 126a without intruding into the radar device 130. Accordingly, the radar device protection structure 100 can balance low cost and high waterproof performance, thereby preventing damage to the radar device 130 and improving safety.

[0050] Furthermore, in this embodiment, as Figures 5 to 7 As shown, the reinforcing member 120 also has an eave-like portion 128 that protrudes inward (e.g., rearward) and connects the first fastening boss 124 and the second fastening boss 126 in the horizontal direction (equivalent to the left-right direction). Preferably, the eave-like portion 128 extends further inward (e.g., rearward) than the radar device 130. That is, the extensions 124a and 126a of the first fastening boss 124 and the second fastening boss 126 can extend horizontally until they connect with each other, and the connected portion constitutes the eave-like portion 128. The extensions 124a of the first fastening boss 124, the extensions 126a of the second fastening boss 126, and the eave-like portion 128 constitute a rib structure that extends continuously in the horizontal direction. Furthermore, the eaves-like portion 128, like the extensions 124a of the first fastening boss 124 and 126a of the second fastening boss 126, further forms a guide structure extending from the inner side (rear side) of the reinforcement 120 towards a position further inward (e.g., rear side) than the radar device 130. This allows for a waterproof effect that spans horizontally across the first fastening boss 124 and the second fastening boss 126. However, in other embodiments not shown, the eaves-like portion 128 may be omitted (i.e., the extensions 124a and 126a are separate from each other). This invention does not limit the specific structure of the eaves-like portion 128, nor its presence or absence, and it can be adjusted as needed.

[0051] Additionally, in this embodiment, as Figures 5 to 7 As shown, the reinforcing member 120 also has a mounting portion 129 located at the upper edge of the radar receiving hole 122. The mounting portion 129 has a top 129a extending inward (e.g., rearward) and a bent portion 129b bending downward from the top 129a, that is, it is configured as a plate structure with an L-shaped cross-section. Wherein, as Figure 6 and Figure 7As shown, the first fastening boss 124 and the second fastening boss 126 are provided in the bending portion 129b, and the top 129a gradually slopes downward from the outside (e.g., the front side) to the inside (e.g., the rear side). Thus, on the inner (rear) side of the reinforcing member 120, the top 129a, the bent portion 129b, and the first fastening boss 124 and the second fastening boss 126 (including their respective extension portions 124a, 126a, and eaves-like portions 128 provided as required) of the mounting portion 129 are configured as a guide structure that extends inward (rear) and gradually downward. The ends of the guide structure, namely the ends of the first fastening boss 124 and the second fastening boss 126 (including extension portions 124a, 126a, and eaves-like portions 128), extend further inward (rear) than the radar device 130. That is, the inward-facing end of the radar device 130 does not exceed the inward-facing end of the guide structure. In this way, water is less likely to accumulate around the reinforcing member 120, but can be further guided inward by the inclined mounting portion 129, and the guiding structures such as the first fastening boss 124 and the second fastening boss 126 (including the extension portion 124a, the extension portion 126a, and the eaves-like portion 128), thereby providing a waterproof effect. However, this utility model is not limited thereto, and can be adjusted according to needs.

[0052] While the waterproofing mechanism provided herein is based on a guide structure consisting of a mounting portion 129 (including a top 129a and a bent portion 129b) and a first fastening boss 124 and a second fastening boss 126 (including an extension portion 124a, an extension portion 126a, and an eaves-like portion 128) on the inner side (e.g., the rear side) of the reinforcement 120, a similar guide structure can also be provided on the outer side (e.g., the front side) of the reinforcement 120 to provide a waterproofing mechanism in other embodiments not shown. For example, an outer eaves-like portion similar to the eaves-like portion 128 can be provided on the outer side (e.g., the front side) of the reinforcement 120, and the upper edge of the cover plate 150 is further positioned above the outer eaves-like portion, forming a labyrinth structure with front-to-back interfering interference between the upper edge of the cover plate 150 and the outer eaves-like portion, thereby achieving a liquid-tight seal. This further prevents water intrusion from the outside, providing a waterproofing effect. However, this invention is not limited thereto and can be adjusted as needed.

[0053] In summary, in the radar device protection structure of this utility model, the reinforcing member within the bumper panel is provided with a first fastening boss and a second fastening boss protruding inwards. The radar device is fastened to the reinforcing member via the first fastening boss, and the camera device is fastened to the reinforcing member via the second fastening boss. The first and second fastening bosses are located at the same horizontal height and extend horizontally, thus improving the rigidity of the mounting structure for the radar device and the camera device. Furthermore, the extended portions of the first and second fastening bosses extend further inwards than the radar device, so even in wet environments such as rainy days, water can slide inwards (e.g., to the rear) from the extended portions without intruding into the radar device. Preferably, the reinforcing member also has an eave-like portion protruding inwards and connecting the first and second fastening bosses in the horizontal direction, thereby providing a waterproof effect across the first and second fastening bosses in the horizontal direction. Therefore, the radar device protection structure of this utility model can balance low cost and high waterproof performance, thereby avoiding damage to the radar device and improving safety.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
