Figure 9 for Figure 8 A partial enlarged view of Figure 10 This is a structural diagram of the sensor mounting bracket and the decorative bracket. Figure 11This is a structural diagram of the sensor mounting bracket installed on the bracket mounting sink, as shown in Figure 1-11 As shown: The automobile fender assembly of this embodiment includes a fender 1 and a sensor mounting bracket 2 mounted on the fender 1, wherein the sensor mounting bracket 2 is clamped to the fender 1; when in use, a sensor 3 is mounted on the sensor mounting bracket 2 and mounted on the fender 1 through the sensor mounting bracket 2. The sensor 3 may be a lidar sensor, and the sensor mounting bracket 2 may be mounted with a lidar sensor and a camera, etc.;

[0032] The fender 1 is provided with a bracket mounting sink, and the sensor mounting bracket 2 is provided with an elastic claw 201. After the sensor mounting bracket 2 is installed on the bracket mounting sink, the elastic claw 201 passes through the bracket mounting sink and clamps the sensor mounting bracket 2 on the fender 1; a bracket mounting sink is provided on the fender 1, that is, the upper part of the fender (upper and lower parts are relative to the upper and lower directions of the car, and upper part is relative to the upper part of the bottom) has a bracket mounting sink formed by being recessed toward the inside (the inside is relative to the inside and outside direction of the car) (that is, the bracket mounting sink is open at both ends in the left and right directions of the car, forming a The structure is similar to a countersunk hole, and the aperture of the outer opening of the bracket mounting sink is larger than the aperture of the inner opening). The sensor mounting bracket 2 is clamped to the bracket mounting sink during installation (that is, it covers at least most of the bracket mounting sink). There can be multiple elastic claws 201, which are distributed at intervals along the edge of the sensor mounting bracket 2. The elastic claws 201 are subjected to external force during the installation process and are deformed, so that the elastic claws 201 can pass through the bracket mounting sink and be clamped on the fender 1, thereby realizing multi-directional fixation of the fender 1 mounting bracket, thereby improving the stability of the fender 1 mounting bracket.

[0033] In the existing technology, DTOF (laser radar sensor) is generally installed on the fender at the front of the car through a bracket, but as the accuracy of DTOF continues to improve, its weight is also increasing, which also brings challenges to the installation, road test, fatigue test and subsequent normal use of DTOF. During the road test, fatigue test and other processes, there are sheet metal deformation and sheet metal fatigue cracking, etc., which will have a great risk of deformation and loosening in the subsequent normal use of users, affecting the appearance evaluation and user experience; in the automobile fender assembly and automobile of the present invention, the sensor mounting bracket 2 is directly clipped to the fender 1 during installation, which is convenient for assembly and improves production efficiency, and through the clip-on method, multi-directional limitation of the sensor mounting bracket 2 can be achieved, which can effectively improve the installation strength, avoid the risk of deformation and loosening of the sensor mounting bracket 2 in subsequent use, and improve user experience.

[0034] In this embodiment, the bracket mounting sink includes a bracket mounting hole 103, and a plurality of abutting surfaces Ⅰ101 are distributed on the edge of the bracket mounting hole 103. The sensor mounting bracket 2 is provided with a plurality of abutting surfaces Ⅱ that cooperate with the abutting surfaces Ⅰ101. After the sensor mounting bracket 2 is installed in the bracket mounting hole 103, the abutting surfaces Ⅰ101 abut against the abutting surfaces Ⅱ; a plurality of abutting surfaces Ⅰ101 are distributed at intervals along the edge of the bracket mounting hole 103, and a plurality of abutting surfaces Ⅱ are distributed at intervals along the sensor mounting bracket 2 and correspond to the positions of the abutting surfaces Ⅰ101. At the same time, the positions of the abutting surfaces Ⅰ101 and the abutting surfaces Ⅱ avoid the positions of the elastic claws 201, so that the elastic claws 201, the abutting surfaces Ⅰ101 and the abutting surfaces Ⅱ do not interfere with each other. After the sensor mounting bracket 2 is installed in the bracket mounting hole 103, the abutting surfaces Ⅰ101 abut against the abutting surfaces Ⅱ, thereby further improving the installation strength of the sensor mounting bracket 2 and reducing the risk of the sensor mounting bracket 2 loosening under certain extreme working conditions.

[0035] In this embodiment, the edge of the bracket mounting hole 103 extends inward to form a sunken platform flange 102, and the edge of the sunken platform flange 102 extends radially to form a sunken platform bottom surface 104. The edge of the sunken platform bottom surface 104 is distributed with multiple abutment surfaces I101. The sensor mounting bracket 2 is provided with multiple abutment portions 202, and the abutment portions 202 are L-shaped structures. The abutment surface II is formed on the vertical surface of the L-shaped structure; inward refers to the inside and outside direction relative to the car, and the sunken platform flange 10 2 extends radially to form the bottom surface 104 of the sinking platform, and a plurality of abutting surfaces Ⅰ101 are distributed on the edge of the bottom surface 104 of the sinking platform (that is, the abutting surface Ⅰ101 is formed by the edge of the bottom surface 104 of the sinking platform extending radially and bending inward), and the abutting portion 202 is an L-shaped structure. During installation, the abutting portion 202 can abut against the abutting surface Ⅰ101, thereby forming a multi-directional limit for the sensor mounting bracket 2, preventing a certain elastic claw 201 from loosening and affecting the installation stability of the sensor mounting bracket 2.

A gap is formed between the elastic limiting portion 2011 and the two side edges of the door-shaped structure. The elastic limiting portion 2011 can swing, so that after the sensor mounting bracket 2 is installed in the bracket mounting hole 103, the bottom of the elastic limiting portion 2011 can be engaged with the bottom surface 104 of the sink; one end of the elastic limiting portion 2011 is connected to the top edge of the door-shaped structure, and the other end extends downward and is located on both sides of the door-shaped structure. The edges are spaced apart and a certain distance is maintained with the two side edges. When the sensor mounting bracket 2 is installed in the bracket mounting hole 103, the elastic limiting portion 2011 is subjected to external force and may swing (i.e., the elastic limiting portion 2011 arranged on the upper part of the sensor mounting bracket 2 swings downward, and the elastic limiting portion 2011 arranged on the lower part of the sensor mounting bracket 2 swings upward, and the up and down directions are relative to the up and down directions of the car), so that the elastic limiting portion 2011 can be extended into the bracket mounting hole 103, and after extending into the bracket mounting hole 103, the elastic limiting portion 2011 returns to its initial position and engages with the bottom surface 104 of the sinking platform, thereby realizing the stable installation of the sensor mounting bracket 2.

Of course, the elastic limiting portion 2011 can also be other shapes. At the same time, after the installation is completed, the bottom edge of the triangular structure is engaged with the bottom surface 104 of the sinking platform, thereby clamping and fixing the sensor mounting bracket 2.

The limiting hole 403 is opened on the flat plate structure. During installation, the flat plate structure is inserted into the limiting slot 203 (the cross-section of the limiting slot 203 is a convex shape), and the limiting ear 2031 is engaged with the limiting hole 403 (the limiting ear 2031 is a structure similar to the elastic limiting part 2011 and can swing), so that the decorative part bracket 4 is firmly installed on the sensor mounting bracket 2.
