In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance.

[0043] As described in the background, the current laser radar installed on the vehicle lamp is easy to transfer the high heat of the laser radar to the lampshade, causing the lampshade to deform due to heat, and the lampshade is also easy to vibrate and rub with the laser radar during driving, which can reduce the installation precision of the laser radar and the matching precision with the lampshade.

[0044] In view of this, the embodiments of the present application provide a laser radar mounting structure for a vehicle lamp, which can precisely position the laser radar on the vehicle lamp and reduce the influence of heat transfer and vibration friction between the laser radar and the lampshade, thereby ensuring the precision of the laser radar.

[0045] It should be noted that the mounting structure provided by the embodiment of the utility model is used for mounting the laser radar on the vehicle lamp, so the mounting structure of the utility model needs to be described in combination with part of the structure of the vehicle lamp and the laser radar, therefore, the part of the vehicle lamp and the laser radar related to the mounting structure will be described first.

[0046] The vehicle lamp can be a front vehicle lamp, a rear vehicle lamp and a high brake lamp of a vehicle, and the vehicle lamp will be described as the high brake lamp as an example.

[0047] For example, referring to Figure 1 , the high brake lamp comprises a lamp shell 500 and a lamp cover 100.

[0048] The lamp shell 500 is a main part of the high brake lamp, is fixed on the vehicle body structure through a fastener and usually has relatively high structural strength.

[0049] The lamp cover 100 is a cover body detachably arranged on the lamp shell 500, plays a role of light control and decoration, is usually made of PMMA (acrylic) material and is easily affected by vibration friction and high temperature deformation.

[0050] Referring to Figure 2 and Figure 4 , the lamp cover 100 is provided with a mounting hole 110, the mounting hole 110 is used for the transceiving end 220 of the laser radar 200 to extend into, so as to facilitate signal emission and signal reception of the laser radar 200 on the high brake lamp.

[0051] For example, referring to Figure 1 and Figure 7 , the laser radar 200 comprises a radar main body 210 and a transceiving end 220 extending outwards from the front end of the radar main body 210, and the area of the front end of the radar main body 210 is greater than that of the transceiving end 220, so that the transceiving end 220 forms a stepped structure at the front end of the radar main body 210.

[0052] Referring to Figure 1 , the laser radar mounting structure provided by the embodiment of the utility model comprises:

[0053] The mounting bracket 300 is fixedly connected to the vehicle lamp and is used for fixing the laser radar 200;

[0054] The limiting assembly 400 is used for limiting the laser radar 200 in the lamp cover 100, so that the transceiving end 220 is positioned in the mounting hole 110, and the limiting assembly 400 comprises:

[0055] The limiting structure 410 is arranged on the lamp cover 100;

[0056] A limiting interval pad 420 is arranged between the laser radar 200 and the limiting structure 410, so that the laser radar 200 is spaced from the lampshade 100 and forms a non-contact positioning.

[0057] According to the laser radar mounting structure, the laser radar 200 is fixed by the mounting bracket 300, and the laser radar 200 is limited by the limiting assembly 400, so that the laser radar 200 is mounted and positioned on the vehicle lamp, the transceiver end 220 of the laser radar 200 extends into the mounting hole 110 on the lampshade 100, and signal transmission and reception of the laser radar 200 is ensured.

[0058] In addition, the laser radar mounting structure is arranged between the laser radar 200 and the limiting structure 410, so that the laser radar 200 can be spaced from the lampshade 100 by the limiting interval pad 420 under the premise that the positioning and mounting precision of the laser radar 200 is ensured by the limiting structure 410, a non-contact positioning is formed, vibration and friction between the laser radar 200 and the lampshade 100 are avoided, direct heat transfer between the laser radar 200 and the lampshade 100 is avoided, the lampshade 100 is prevented from being deformed due to high temperature, the lampshade 100 is protected, and the service life of the lampshade 100 is prolonged.

[0059] The laser radar mounting structure for a vehicle lamp provided by the embodiment of the utility model will be described in detail below with reference to the drawings.

[0060] According to Figure 1 The laser radar mounting structure for a vehicle lamp provided by the embodiment of the utility model will be described in detail below with reference to the drawings.

[0061] The mounting bracket 300 is arranged to fix and mount the laser radar 200 on the vehicle lamp, so as to ensure the mounting stability of the laser radar 200.

[0062] For example, referring to Figure 1 and Figure 7 In the embodiment, the mounting bracket 300 comprises a rear cover plate, and one end of the laser radar 200 away from the transceiver end 220 is fixedly connected with the rear cover plate by a screw or other fastener, so that the laser radar 200 and the rear cover plate form an integrated structure, and when the mounting bracket 300 is mounted, the rear cover plate is fixedly connected with the vehicle lamp structure, so that the laser radar 200 is fixedly mounted on the vehicle lamp.

[0063] Further, referring to Figure 1In the embodiment, the mounting bracket 300 is fixedly connected to the lamp shell 500 of the vehicle lamp, that is, the laser radar 200 is fixedly connected to the lamp shell 500 through the mounting bracket 300. In this way, the weight of the laser radar 200 is mainly borne by the lamp shell 500. Since the lamp shell 500 has good connection stability and large structural strength with the vehicle body structure, the mounting stability of the laser radar 200 can be better ensured compared with the case that the laser radar 200 is borne by the lamp cover 100, the load borne by the lamp cover 100 is reduced, the risk of fragmentation of the lamp cover 100 is reduced, and the service life of the lamp cover 100 is ensured.

[0064] Further, referring to Figure 1 and Figure 7 , the mounting bracket 300 and the lamp shell 500 are fixedly connected in a hole-to-hole screw connection mode. For example, the rear cover plate and the lamp shell 500 are provided with a plurality of sets of opposite threaded holes. During installation, the threaded holes on the rear cover plate are aligned with the threaded holes on the lamp shell 500, and then the threaded holes are fastened with screws to realize the fixation of the mounting bracket 300 on the lamp shell 500. In this way, compared with welding which is prone to errors and causes the mounting angle of the laser radar 200 to deviate, the hole-to-hole positioning mode can ensure the accurate positioning of the mounting bracket 300, thereby ensuring the positioning accuracy of the laser radar 200.

[0065] In the embodiment, the limiting assembly 400 is used to limit the laser radar 200 in the lamp cover 100, so that the transceiver end 220 is accurately positioned in the mounting hole 110, thereby providing a basis for the high sensing accuracy of the laser radar 200.

[0066] Specifically, referring to Figure 1 , in the embodiment, the limiting assembly 400 includes a limiting structure 410 arranged on the lamp cover 100 and a limiting spacing pad 420 used to limit the laser radar 200 at intervals on the limiting structure 410. In this way, the limiting structure 410 and the limiting spacing pad 420 can realize the accurate positioning of the laser radar 200 and the isolation between the laser radar 200 and the lamp cover 100, thereby avoiding the vibration friction and high temperature transmission between the laser radar 200 and the lamp cover 100.

[0067] Among them, referring to Figure 5 , the limiting structure 410 includes an axial limiting structure 412 and a radial limiting structure 411.

[0068] The axial limiting structure 412 is used in combination with the limiting and spacing pad 420 to limit the laser radar 200 in the axial direction, so as to achieve a desired effect of matching the appearance between the transceiving end 220 of the laser radar 200 and the outer side surface of the lampshade 100 in the axial direction, and ensure the overall aesthetic appearance. It should be noted that in the description of the present application, the axial direction of the laser radar 200 can be understood as the front-rear direction of the laser radar 200.

[0069] For example, referring to Figure 2 , after the laser radar 200 is axially limited on the lampshade 100 by the axial limiting structure 412 and the limiting and spacing pad 420, the difference between the outer end surface of the laser radar 200 and the outer side surface of the lampshade 100 is less than 0.5 mm, so that the transceiving end 220 of the laser radar 200 and the outer side surface of the lampshade 100 are substantially flush in appearance.

[0070] Specifically, referring to Figure 1 and Figure 5 , in the embodiment, the axial limiting structure 412 includes a limiting surface 4121 arranged on the inner side surface of the lampshade 100. The limiting surface 4121 can be a part of the inner side surface of the lampshade 100, or a concave or convex surface machined on the inner side surface of the lampshade 100, which is not limited here. In this way, by defining the limiting surface 4121 on the inner side surface of the lampshade 100, the front end of the radar main body 210 can be limited on the inner side surface of the lampshade 100, thereby providing a basis for axial limiting of the laser radar 200.

[0071] Correspondingly, the limiting and spacing pad 420 is arranged at least partially between the front end of the radar main body 210 and the limiting surface 4121, so as to space the front end of the radar main body 210 and the limiting surface 4121, thereby avoiding direct contact between the front end of the radar main body 210 and the lampshade 100 while ensuring the axial positioning of the laser radar 200.

[0072] Further, the profile of the limiting surface 4121 matches the profile of the front end surface of the radar main body 210. For example, referring to Figure 5 and Figure 7 , the profile of the front end surface of the radar main body 210 is annular, and the limiting surface 4121 can also be arranged in an annular shape around the peripheral side of the mounting hole 110, so that the front end of the radar main body 210 can be better limited on the limiting surface 4121, thereby ensuring the installation and positioning accuracy of the laser radar 200.

[0073] For example, referring to Figure 1 and Figure 5 , the inner side surface of the lampshade 100 is provided with an annular mounting groove, and the bottom wall of the mounting groove is the limiting surface 4121. The mounting groove facilitates limiting and spacing the limiting and spacing pad 420 in the axial and radial directions.

[0074] Based on the above designed axial limiting structure 412, during installation, the laser radar 200 is pushed forward from inside to outside by the installation support 300 until the front end of the radar main body 210 is limited on the limiting surface 4121 on the inner side of the lampshade 100 by the limiting spacing pad 420. Thus, the laser radar 200 can be axially limited between the installation support 300 and the lampshade 100, and accurate positioning of the laser radar 200 in the axial direction is achieved.

[0075] In the present embodiment, the radial limiting structure 411 is used to limit the laser radar 200 in the radial direction in combination with the limiting spacing pad 420, so that the transceiver end 220 of the laser radar 200 is accurately positioned in the mounting hole 110, and the appearance matching between the transceiver end 220 of the laser radar 200 and the outer side of the lampshade 100 in the radial direction achieves a desired effect, ensuring the overall aesthetic appearance. It should be noted that in the description of the context of the present application, the radial direction of the laser radar 200 can be understood as the direction perpendicular to the front-rear direction of the laser radar 200.

[0076] For example, referring to Figure 1 and Figure 2 , after the laser radar 200 is radially limited on the lampshade 100 by the radial limiting structure 411 and the limiting spacing pad 420, the transceiver end 220 of the laser radar 200 is positioned in the mounting hole 110, and there is a gap between the outer circumferential side of the transceiver end 220 and the hole wall of the mounting hole 110. The transceiver end 220 of the laser radar 200 is in clearance fit with the mounting hole 110, so that the transceiver end 220 does not directly contact the lampshade 100, avoiding vibration friction and high heat transfer of the laser radar 200 to the lampshade 100.

[0077] Further, the gap between the transceiver end 220 and the hole wall of the mounting hole 110 is small enough, for example, less than 0.5mm, so that the transceiver end 220 and the lampshade 100 have a good appearance matching effect, improving the overall aesthetic appearance.

[0078] Specifically, referring to Figure 5 , in the present embodiment, the radial limiting structure 411 includes first limiting members 4111 distributed on both sides of the mounting hole 110 in a first direction and second limiting members 4112 distributed on both sides of the mounting hole 110 in a second direction, wherein the first direction and the second direction are two radial directions of the laser radar 200. For example, in the orientation shown in Figure 5 , the first direction is the left-right direction of the mounting hole 110, and the second direction is the up-down direction of the mounting hole 110. Based on this, the left-right limiting of the laser radar 200 on both sides of the mounting hole 110 is achieved by the first limiting members 4111, and the up-down limiting of the laser radar 200 on both sides of the mounting hole 110 is achieved by the second limiting members 4112, so that the overall radial limiting of the laser radar 200 is achieved.

[0079] Referring to Figure 5 In a specific example, the first limiting member 4111 and the second limiting member 4112 can be rib plates protruding on the inner side surface of the lampshade 100, and the length extension direction of each rib plate is in the radial direction of the lidar 200. In this way, the structural strength of the rib plate in the limiting direction can be improved, thereby ensuring the stability of the limiting of the lidar 200.

[0080] Further, in the present embodiment, each side of the mounting hole 110 has at least two limiting members, and each limiting member is distributed, for example, Figure 5 The example shows an implementation in which the left and right sides of the mounting hole 110 each have two first limiting members 4111, and the upper and lower sides each have two second limiting members 4112. In this way, more and more dispersed limiting points can be provided on the peripheral side of the mounting hole 110 for the lidar 200, thereby improving the stability of the limiting of the lidar 200.

[0081] Correspondingly, referring to Figure 1 , and Figure 6 The limiting interval pad 420 is at least partially arranged between the outer peripheral side of the lidar 200 and each limiting member to space the lidar 200 and each limiting member apart, thereby ensuring the radial positioning of the lidar 200 while avoiding direct contact between the outer peripheral side of the lidar 200 and the lampshade 100.

[0082] Based on the above, in the present embodiment, each position on the lidar 200 corresponding to the limiting structure 410 is spaced apart by the limiting interval pad 420, which can ensure the isolation of the lidar 200 and the lampshade 100, avoid the vibration and friction of the lidar 200 on the lampshade 100, reduce the heat transfer between the lidar 200 and the lampshade 100, and improve the service life of the lampshade 100.

[0083] In the present embodiment, the limiting interval pad 420 is specifically an annular pad, and in the axial direction, the side of the limiting interval pad 420 close to the mounting hole 110 is used for limiting abutment with the limiting surface 4121, and the side away from the mounting hole 110 is used for limiting abutment with the lidar 200; in the radial direction, the inner hole of the limiting interval pad 420 is used for sleeving on the transceiver end 220, and the outer peripheral side is used for limiting abutment with the first limiting member 4111 and the second limiting member 4112.

[0084] For example, referring to Figure 1 and Figure 6, the limiting and spacing pad 420 is an oval ring, and the inner hole profile thereof matches the outer peripheral profile of the transceiving end 220, so that the limiting and spacing pad 420 can be sleeved on the transceiving end 220 of the laser radar 200 and located at the front end of the radar main body 210, facilitating the axial spacing of the limiting and spacing pad 420 between the inner side of the lampshade 100 and the radar main body 210 during installation. Meanwhile, the outer peripheral profile of the limiting and spacing pad 420 matches the limiting profile surrounded by each limiting piece, so that the limiting and spacing pad 420 can be just embedded between each limiting piece, realizing radial limiting.

[0085] Based on the limiting and spacing pad 420 designed in the above structure, during installation, the limiting and spacing pad 420 is sleeved on the transceiving end 220 of the laser radar 200 in advance, so that the limiting and spacing pad 420 can be abutted and limited by the limiting face 4121 and each limiting piece during the installation of the laser radar 200, so as to ensure the accurate installation and positioning of the laser radar 200, and also ensure the isolation of the laser radar 200 and the lampshade 100, avoiding the vibration friction and high heat transfer of the laser radar 200 to the lampshade 100.

[0086] Of course, in other embodiments, the limiting and spacing pad 420 can also be of a split structure, for example, the limiting and spacing pad 420 can include a first pad body arranged between the laser radar 200 and the limiting face 4121 and a second pad body arranged between the laser radar 200 and each limiting piece, and correspondingly, each first pad body and second pad body of the split structure can be arranged at the corresponding positions in the inner side of the lampshade 100 or on the corresponding positions of the laser radar 200 in a mutually independent manner in advance, which can also ensure the isolation of the laser radar 200 and the lampshade 100 after the laser radar 200 is installed in place.

[0087] Further, in the present embodiment, the limiting and spacing pad 420 is made of a heat-insulating and / or wear-resistant material, for example, the limiting and spacing pad 420 can be made of rubber material, so that the heat transfer between the laser radar 200 and the lampshade 100 can be further reduced, the problem of deformation of the lampshade 100 due to high temperature can be avoided, and the vibration between the laser radar 200 and the lampshade 100 can be buffered, thereby improving the protection effect on the lampshade 100.

[0088] Referring to Figure 1 In the present embodiment, the limiting and spacing pad 420 is further provided with an extension 421 on the side facing the mounting hole 110, and the extension 421 is embedded into at least part of the gap between the transceiving end 220 and the hole wall of the mounting hole 110, so that the limiting and spacing of the limiting and spacing pad 420 in the gap between the transceiving end 220 and the hole wall of the mounting hole 110 can ensure the stability of the gap, avoid the contact between the transceiving end 220 and the lampshade 100, and improve the isolation effect between the laser radar 200 and the lampshade 100.

[0089] Specifically, referring to Figure 1 In the through direction of the mounting hole 110, the mounting hole 110 is shaped like a cone with a large inner diameter and a small outer diameter, so that the inner end hole wall of the mounting hole 110 and the outer circumferential side of the transceiver end 220 have a larger gap, so as to facilitate the embedding of the extension part 421 of the limiting spacing pad 420. In order to improve the adaptability, the outer contour of the extension part 421 can be set to be conical to match the inner end part of the mounting hole 110.

[0090] The technical features of the above embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered as the scope of the description.

[0091] The above embodiments only express several implementation manners of the application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the application, a number of modifications and improvements can be made, which all belong to the protection scope of the application. Therefore, the protection scope of the patent of the application should be subject to the appended claims.
