[0034] In the description of the embodiments of the present application, the technical terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the embodiments of the present application.
[0035] In view of the technical problems existing in the prior art such as insufficient structural strength of the laser radar decorative cover, the lack of an integrated automatic cleaning device, and high wind noise, the present invention provides a laser radar decorative cover for decorating a laser radar of a vehicle, such as Figure 1 As shown, including:
[0036] The front decorative cover 1 and the upper decorative cover 2 are connected to each other; Figure 2 As shown, a self-cleaning nozzle 3 is integrated on the front decorative cover 1 and is arranged between the laser radar 4 and the upper decorative cover 2. The liquid outlet of the self-cleaning nozzle 3 faces the optical window of the laser radar 4 and is used to clean the optical window of the laser radar 4.
[0037] Specifically, the laser radar decorative cover in this embodiment integrates a self-cleaning nozzle 3, which can be connected to a washing system. When dust and other debris block the laser radar's optical window, washing liquid is sprayed on the laser radar's optical window to automatically clean the laser radar's optical window to avoid affecting the normal operation of the laser radar. In addition, the front decorative cover 1 and the upper decorative cover 2 are connected to each other to form a space for accommodating the laser radar 4, which shields the laser radar 4, can play a decorative and protective role, and enhance the beauty of the entire vehicle.
[0038] As an optional implementation, Figure 3 and Figure 4 As shown, the front decorative cover 1 includes:
[0039] The outer panel 101 and the frame 102 are connected by welding; the frame 102 is fixed to the roof metal bracket 5 of the vehicle by screws or a first metal clip 103 .
[0040] Specifically, Figure 5 Schematic diagram of the structure in which the front decorative cover and the roof metal bracket 5 are installed by screws 104. The outer panel 101 and the frame 102 are connected to each other. The frame 102 is provided with screw mounting holes. The screws 104 pass through the through holes on the roof metal bracket 5 and enter the screw mounting holes to fix the frame 102 and the roof metal bracket 5 together, thereby fixing the front decorative cover to the roof. Figure 6It is a structural schematic diagram of the front decorative cover and the roof metal bracket 5 installed through the first metal clip 103. The outer panel 101 and the frame 102 are connected to each other. The frame 102 is provided with a protrusion, which passes through the through hole on the roof metal bracket 5 and is fixed by the first metal clip 103, fixing the frame 102 and the roof metal bracket 5 together, thereby fixing the front decorative cover to the roof.
[0041] As an optional implementation, Figure 3 As shown, the outer plate 101 is provided with a first positioning pin 1011 and a first welding rib 1012, and a plurality of first reinforcing ribs are provided on both sides of each first welding rib 1012; the frame 102 is provided with a second welding rib, a welding hole, a second positioning pin, a second reinforcing rib, a screw mounting seat, a clamping mounting hole or a screw mounting hole. In this embodiment, the outer plate 101 and the frame 102 are fixed by welding, and reinforcing ribs are used to enhance the structural strength of the laser radar decorative cover.
[0042] As an optional implementation, Figure 7 As shown, the front decorative cover 1 also includes a sealing strip 105, such as Figure 5 and 6 As shown, a portion of the sealing strip 105 is fixed to the bottom of the outer panel 101 , and another portion is used to fill the gap between the outer panel 101 and the frame 102 .
[0043] Specifically, the sealing strip 105 in this embodiment has its own adhesive backing and can be pasted to the bottom of the outer panel 101. After the outer panel 101 and the frame 102 are welded, part of the structure of the sealing strip 105 is filled in between the outer panel 101 and the frame 102 as an interlayer. The main function of the sealing strip is to enhance the aesthetics of the laser radar decorative cover, and it can well shield the gap between the laser radar decorative cover and the front windshield 6 of the vehicle, while facilitating disassembly and maintenance.
[0044] As an optional implementation, Figure 4 As shown, a plurality of first sponge strips 106 are provided on one side of the frame 102 facing the laser radar 4, which can reduce wind noise. Figure 3 As shown, the outer panel 101 and the laser radar 4 have a plurality of protrusions 1013 in the matching area, which play the function of maintaining the good appearance of the laser radar decorative cover and the laser radar.
[0045] As an optional implementation, Figure 7 As shown, strip grilles 107 are provided on both sides of the window of the outer panel 101, which serve as air inlets of the front decorative cover 1. On the one hand, they help to dissipate heat of the laser radar. On the other hand, since the strip grilles 107 enhance the ventilation function, after the self-cleaning nozzle 3 sprays detergent on the laser radar's light window to clean it, the evaporation of water droplets remaining on the laser radar's light window is accelerated, thereby keeping the surface of the laser radar's light window dry.
[0046] As an optional implementation, Figure 8 and 9 As shown, the upper decorative cover 2 includes an upper decorative cover body 201, sound-absorbing cotton 202, a second sponge strip 203 and a plurality of second metal clips 204; wherein the sound-absorbing cotton 202 is arranged at a position of the upper decorative cover body 201 corresponding to the laser radar 4, and the second sponge strips 203 are respectively arranged on both sides of the upper decorative cover body 201.
[0047] Specifically, in this embodiment, the sound-absorbing cotton 202 has its own adhesive backing and can be attached to the upper decorative cover body 201 to absorb sound and reduce noise. Fig. 9 As shown, the second sponge strip 203 can be attached to the circumference of the upper decorative cover 2 to reduce wind noise.
[0048] As an optional implementation, Figure 8 As shown, square grilles 205 are provided on both sides of the upper decorative cover 2 to provide air inlets for the laser radar self-cleaning system, accelerate the evaporation of water droplets remaining on the laser radar window, and keep the surface of the laser radar window dry.
[0049] As an optional implementation, Fig.10 As shown, the self-cleaning nozzle 3 can be fixed above the window of the front decorative cover 1 by means of a limiting structure and screws, forming a certain angle with the optical window of the laser radar, so as to facilitate spraying cleaning liquid onto the optical window of the laser radar.
[0050] The present disclosure also provides a vehicle, including a laser radar 4, and the vehicle also includes a laser radar decorative cover as described in any one of the above embodiments.
[0051] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps recorded in this disclosure can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of this disclosure can be achieved, and this document is not limited here.
[0052] The above specific implementations do not constitute a limitation on the protection scope of the present disclosure. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
