Description

Technical Field

[0001] This invention belongs to the field of lidar cover technology and relates to an improved assembly structure of lidar cover and lidar cover panel. Background Technology

[0002] With the development of intelligent driving technology, LiDAR, as an important environmental perception sensor, is increasingly being installed on the front of car roofs. LiDAR is typically protected by a radome, and to improve the overall appearance, exterior decorative panels are often added to both sides of the radome. Currently, the connection between the exterior decorative panels and the radome body mainly uses a Y-axis (vehicle front-to-rear) snap-fit ​​method supplemented by double-sided adhesive tape. This solution has significant drawbacks: because the snaps of the exterior decorative panels are usually cantilever structures arranged along the Y-axis, their stress points are far from the fixed ends of the snaps, forming a long cantilever beam. During radome assembly or when subjected to external loads (such as car washing or high-speed wind resistance), this long cantilever structure is prone to deformation, placing extremely high demands on the snaps themselves. This often leads to snaps breaking during assembly or loosening due to plastic deformation and fatigue during use, causing the exterior decorative panels to detach and affecting the vehicle's appearance and functionality. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an improved assembly structure for a laser radar dome and radar dome decorative panel that is structurally stable, reliably assembled, and can effectively resist multi-directional forces, in view of the current state of the prior art. This overcomes the defects of the existing radar dome outer decorative panel connection structure, such as long cantilever, easy deformation, and easy detachment.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: an improved assembly structure of a laser radar dome and a radar dome decorative panel, characterized in that it includes: The radar dome body is assembled from an inner radar dome panel and an outer radar dome panel, with a lidar mounting slot formed in the middle. At least one outer decorative panel is disposed on the side of the outer panel of the radome. The outer decorative panel includes an external appearance surface facing outward and a mounting surface facing the outer panel of the radome. Three buckles are provided on the mounting surface. The outer panel of the radome has a matching groove that cooperates with the buckles. The three buckles are installed into the matching groove and are arranged in a triangle to prevent them from falling off.

[0005] As a further optimization, in the above-mentioned improved assembly structure of the lidar cover and lidar cover panel, the three buckles include a first buckle, a second buckle and a third buckle, and the corresponding matching slots include a first matching slot, a second matching slot and a third matching slot. The matching slots corresponding to the second buckle and the third buckle extend in a direction that is basically perpendicular to the assembly direction, so that the second buckle and the third buckle can be rotated and snapped into place.

[0006] As a further optimization, in the above-mentioned improved assembly structure of the lidar cover and lidar cover panel, the first buckle has an anti-detachment rib, and the first buckle has an interference fit when the first buckle is pre-installed in the first clip slot.

[0007] As a further optimization, in the above-mentioned improved assembly structure of the lidar cover and lidar cover panel, an elastic groove is provided next to the first card slot.

[0008] As a further optimization, in the above-mentioned improved assembly structure of the lidar cover and lidar cover panel, the first locking groove extends along the Z direction, the second locking groove and the third locking groove extend along the X direction or the combined direction of the X and Z directions, and the assembly direction of the outer decorative panel relative to the outer panel of the lidar cover is the Y direction.

[0009] As a further optimization, in the above-mentioned improved assembly structure of the lidar cover and lidar cover panel, both the second buckle and the third buckle are provided with anti-detachment ribs. The anti-detachment ribs are used to limit the second buckle and the third buckle in the Y direction after they are engaged in the corresponding matching slots.

[0010] As a further optimization, in the above-mentioned improved assembly structure of the lidar cover and lidar cover panel, a pre-positioning component is also provided on the mounting surface of the outer decorative panel, and a pre-positioning groove is correspondingly provided on the outer panel of the lidar cover, for pre-positioning the outer decorative panel before the first buckle slides into the first matching groove.

[0011] As a further optimization, in the above-mentioned improved assembly structure of the lidar cover and lidar cover panel, double-sided tape is also provided between the mounting surface of the outer decorative panel and the outer panel of the lidar cover. The double-sided tape and the buckle together form a secondary protection structure and prevent the outer decorative panel from detaching when the buckle fails.

[0012] As a further optimization, in the above-mentioned improved structure of the lidar cover and lidar cover panel assembly, the lidar cover body is provided with symmetrical outer decorative panels on both sides.

[0013] As a further optimization, in the above-mentioned improved assembly structure of the lidar cover and lidar cover panel, the outer decorative panel is provided with local positioning ribs around its perimeter.

[0014] Compared with existing technologies, the advantages of this invention are that the triangularly distributed buckles and corresponding matching slots form effective limiting in multiple directions (X, Y, Z), significantly shortening the force arm of a single buckle and transforming the long cantilever structure into a short and stable support. This fundamentally solves the problems of buckle deformation and breakage. When assembling the outer decorative panel, a rotating oblique insertion installation is used. After repeated simulations and verifications of assembly feasibility, it does not increase assembly difficulty or time. The addition of X-direction limiting at the end shortens the force arm of the product and increases the connection strength of the decorative panel. The structure is compact, does not add much extra space or weight, and is easy to integrate into existing radome designs, exhibiting good versatility and promotional value.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] In the diagram: Radar radome body 100; outer decorative panel 200; exterior surface 201; mounting surface 202; inner radar radome panel 300; outer radar radome panel 400; fastener 500; sealing foam strip 600; first fastener 700; second fastener 800; third fastener 900; first locking groove 1000; second locking groove 1001; third locking groove 1002; anti-detachment rib 1003; elastic groove 1004; pre-positioning component 1005; pre-positioning groove 1006; double-sided adhesive tape 1007; local positioning rib 1008; lidar mounting groove 1009.

[0019] like Figure 1 As shown, this improved structure of the lidar cover and lidar cover panel assembly includes a lidar body 100 and an outer decorative panel 200. The lidar body 100 is assembled from an inner lidar panel 300 and an outer lidar panel 400. The inner lidar panel 300 and the outer lidar panel 400 are connected to each other by means of fasteners 500, adhesives, etc. For sealing, sealing foam strips 600 are arranged around the perimeter. A lidar mounting groove 1009 is formed in the middle of the lidar body 100. The outer decorative panels 200 are symmetrically arranged on both sides of the lidar body 100. In this way, the lidar cover can be installed between the two outer decorative panels 200 to form an integral fixed structure, which is secure and stable.

[0020] like Figure 2 as well as Figure 3 As shown, specifically, the outer decorative panel 200 is disposed on the side of the radome outer panel 400. The outer decorative panel 200 includes an external appearance surface 201 facing outward and a mounting surface 202 facing the radome outer panel 400. Three clips are provided on the mounting surface 202. The radome outer panel 400 has a matching groove that mates with the clips. The three clips are installed into the matching groove and arranged in a triangular pattern to prevent detachment. Here, the triangular arrangement of the clips in this patent provides stable three-point support, preventing the outer decorative panel 200 from rotating or warping under force. It effectively limits movement in multiple directions (X, Y, Z), evenly distributing external force, reducing the load on individual clips, and significantly shortening the lever arm of a single clip, effectively solving the problem of detachment caused by excessively long cantilever arms in traditional designs.

[0021] The three clips include a first clip 700, a second clip 800, and a third clip 900, with corresponding locking slots including a first locking slot 1000, a second locking slot 1001, and a third locking slot 1002. The locking slots for the second clip 800 and the third clip 900 extend in a direction substantially perpendicular to the assembly direction, allowing the second clip 800 and the third clip 900 to rotate and engage. The first clip 700 has an anti-detachment rib 1003. The first clip 700 has an interference fit when pre-installed with the first locking slot 1000. The first buckle 700 is provided with an anti-detachment rib 1003, which forms an interference fit during pre-assembly to provide initial fixing force. An elastic groove 1004 is provided next to the first locking groove 1000. Here, the first buckle 700 is used as the installation starting point in this patent. The elastic groove 1004 enables the wall panel where the first locking groove 1000 is located to have elastic deformation capability, providing clearance space for the first buckle 700 to slide in, reducing the insertion force when the first buckle 700 slides in, avoiding cracking of the buckle or locking groove, improving pre-assembly stability, and allowing a certain assembly tolerance.

[0022] Both the second buckle 800 and the third buckle 900 are provided with anti-detachment ribs 1003. The anti-detachment ribs 1003 are used to limit the movement of the second buckle 800 and the third buckle 900 in the Y direction after they are engaged in the corresponding locking slots. The anti-detachment ribs 1003 on the second buckle 800 and the third buckle 900 are specifically designed to limit the displacement in the Y direction (i.e., the direction in which the outer decorative panel 200 is disengaged) and to act as the main support structure to prevent detachment. The first locking slot 1000 extends in the Z direction, and the second locking slot 1001 and the third locking slot 1002 extend in the X direction or the combined direction of the X and Z directions. The assembly direction of the outer decorative panel 200 relative to the radar dome outer panel 400 is in the Y direction. The second locking slot 1001 and the third locking slot 1002 make the movement trajectory of the buckle perpendicular to the Y direction when it is rotated and engaged, thereby forming a mechanical self-locking in the Y direction, which greatly improves the resistance to detachment in the Y direction.

[0023] The mounting surface 202 of the outer decorative panel 200 is also provided with a pre-positioning component 1005, and the outer panel 400 of the radar cover is provided with a corresponding pre-positioning groove 1006. This is used to pre-position the outer decorative panel 200 before the first buckle 700 slides into the first matching groove 1000. Here, the cooperation between the pre-positioning component 1005 and the pre-positioning groove 1006 temporarily fixes the outer decorative panel 200 in the correct position, improving assembly efficiency and yield. This patent uses the first buckle 700 to pre-install and interfere with the first matching groove 1000, and then rotates and snaps in the structure so that the Y-direction tension borne by the second buckle 800 and the third buckle 900 in the final locked state is converted into positive pressure on the side wall of the matching groove, which has strong anti-detachment force. After final installation, it forms effective limit in multiple directions of X, Y, and Z, realizing that the strong anti-detachment ribs at the near end serve as the main support structure to prevent detachment, and the buckles at the far end provide secondary protection to prevent the outer decorative panel 200 from detaching.

[0024] To further enhance the anti-detachment effect, double-sided adhesive tape 1007 is also provided between the mounting surface 202 of the outer decorative panel 200 and the outer radome panel 400. The double-sided adhesive tape 1007, together with the clips, forms a secondary protection structure to prevent the outer decorative panel 200 from detaching in case of clip failure. This secondary protection using double-sided adhesive tape 1007 solves the detachment problem. In addition, local positioning ribs 1008 are provided around the perimeter of the outer decorative panel 200. These local positioning ribs 1008 ensure a uniform gap between the outer decorative panel 200 and the outer radome panel 400, preventing warping or localized dents, improving the overall rigidity after assembly, and reducing relative displacement during vibration.
