Description

Technical Field

[0001] The utility model relates to the field of automobile technology, and in particular to a radar module mounting bracket. Meanwhile, the utility model also relates to a vehicle provided with the radar module mounting bracket. Background Art

[0002] Automotive radar, as the name implies, is a radar used in cars or other ground motor vehicles. Therefore, it includes radars based on different technologies, with different functions (such as obstacle detection, collision prediction, adaptive cruise control), and using different working principles (such as pulse radar, FMCW radar, microwave impact radar). Radar plays an important role in the safe driving of automobiles, and many modern motor vehicles are equipped with radar systems for detecting objects and the position of these objects relative to the motor vehicle. These radar systems can be used to provide parking assistance, adaptive cruise control, and pre-collision braking features, etc.

[0003] In many cases, the radar module and the bracket for fixing the radar module are located on the bumper structure of the motor vehicle. In the prior art, the installation structure of the radar generally adopts an all-inclusive protection method, that is, the radar is set in a closed box, and then installed on the bumper structure of the vehicle. When the vehicle is driving on a bumpy road or is subjected to similar excitations such as a collision, it is easy to generate vibrations. When these vibrations are transmitted to the radar module and the bracket for fixing the radar module, the collision force generated will exert pressure on the radar module or the radar support bracket, and even the bracket for fixing the radar module will be affected by external forces, resulting in damage or deviation of the radar module.

[0051] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0052] Embodiment 1

[0053] The present embodiment relates to a radar module mounting bracket, which is used to mount a radar module 2 on a bumper 3 of a vehicle. The radar module mounting bracket includes: a bracket body 1, which is fixedly connected to the bumper 3; the bracket body 1 is constructed into a plate shape extending along the bumper 3; a hollow portion 101 is formed on the bracket body 1; a connecting piece is arranged on the bracket body 1; the connecting piece constitutes the installation of the radar module 2 on the bracket body 1, and keeps the radar module 2 within the area encircled by the hollow portion 101; and a spacing is set between the radar module 2 and the bumper 3.

[0054] Based on the above overall introduction, an exemplary structure of the radar module mounting bracket described in this embodiment is as follows: Figure 1 , 2 and Figure 5 The radar module mounting bracket can fix the radar module 2 to the bumper 3. The radar module 2 transmits and receives feedback signal waves, which are transmitted to the computer control module (electronic control unit, referred to as ECU or driving computer) through the wiring harness 6. The computer control module calculates the received wave signals to complete the detection and identification of obstacles around the bumper 3.

[0055] The main appearance shape of the radar module mounting bracket of this embodiment can be constructed as a plate-like shape extending along the bumper 3, so that the fixing position fits the bumper 3, and the bracket body 1 is more firmly and stably matched with the bumper 3 when installed. In order to install and place the radar module 2, this embodiment opens a hollow part 101 on the bracket body 1, which can not only keep the radar module 2 in the area enclosed by the hollow part 101, but also save the material of the bracket body 1. The shape around the hollow part 101 can be constructed to support the radar module 2. When the radar module 2 is installed on the bracket body 1 through the connecting piece, a certain distance is provided between the radar module 2 and the bumper 3. In this way, when the vehicle is violently bumped, the radar module 2 can be effectively prevented from colliding with the bumper 3, so as to protect the radar module 2. The above-mentioned connecting piece can be connected by a threaded structure for easy fixing and installation. Of course, it can also be riveted or clamped. The connection method can be flexibly selected according to the structure of the fixed part of the radar module 2.

[0056] like Figure 8 As shown, as a feasible implementation, the fixing part of the radar module 2 is the ear plates 201 protruding from the two opposite sides of the radar module 2 body, and the number of the ear plates 201 can be set to be multiple. In order to adapt to the fixing part of the radar module 2, on the bracket body 1 on the two opposite sides of the radar module 2, Figure 1A protruding support rib 103 is formed at the edge of the hollow portion 101, and the ear plate 201 of the radar module 2 is fixedly placed on the support rib 103. The arrangement of the support rib 103 allows the radar module 2 to be fixedly mounted in the hollow portion 101 through the ear plate 201, thereby maintaining a certain distance between the radar module 2 and the bumper 3. Such a structure can further buffer the vibration caused by the bumping of the vehicle, effectively preventing the radar module 2 from colliding with the bumper 3; in addition, it can also strengthen the strength of the radar module mounting bracket.

[0057] In order to make the connection between the radar module 2 and the bracket body 1 more stable and firm, Figure 3 As shown, preferably, the ear plates 201 of this embodiment are distributed in a triangular shape on two opposite sides of the radar module 2. The triangle has stability and can be connected to form a triangle with the fixed positions of the radar module 2 as vertices. Such a fixed position distribution can make the radar module 2 more stable and secure to install. In addition, the ear plate 201 of the radar module 2 can also have a positioning function. In order to adapt to the shape of the ear plate 201, the connection between the bracket body 1 and the ear plate 201 can be constructed as a limiting groove 102 that can accommodate the ear plate 201. The ear plate 201 and the limiting groove 102 can be gap-matched, and the preferred gap is 0.1mm-0.2mm, so that the radar module 2 has both the effect of convenient installation and firm fixation.

[0058] In order to fix the bracket body 1 more firmly when it is installed on the bumper 3, on the bracket body 1 around the hollow part 101, as shown in FIG. Figure 3 and Figure 4 As shown, a plurality of welding areas are provided for welding the bracket body 1 to the bumper 3. In this embodiment, there are 5 welding areas, which are circumferentially surrounded by the hollow area, so that the force of the bracket body 1 on the bumper 3 can be more uniform, which is beneficial to improve the durability of the fixed structure. Of course, the number of welding sites 104 can also be adjusted according to the actual shape of the bracket, so that the bracket can be firmly connected to the bumper 3. The welding method can be flexibly selected according to the material to be welded. In this embodiment, puncture welding is preferably used. The puncture welding process has the advantages of saving materials, short processing time, and high safety.

[0059] In addition, in order to facilitate the implementation of the welding process, a preferred method of this embodiment is that an adhesive portion 105 for bonding the bracket body 1 to the bumper 3 before welding the bracket body 1 to the bumper 3 is provided on the bracket body 1 adjacent to the edge of the bracket body 1. In this embodiment, 3M double-sided tape can be used to pre-bond the adhesive portion 105 on the bracket body 1, and then the bracket body 1 is bonded to the bumper 3, and after bonding, the bracket body 1 can be further welded and fixed. The adhesive portion 105 of this embodiment is set at two places to make the bracket body 1 more stable during bonding.

[0060] In order to make the installation position of the bracket body 1 on the bumper 3 more accurate, a positioning mechanism for positioning the installation position of the bracket body 1 is provided between the bumper 3 and the bracket body 1, such as Figure 4-6 As shown. The positioning mechanism is used to position the installation position of the bracket body 1 on the bumper 3, which can effectively prevent positioning deviations caused by mistakes. Furthermore, the positioning mechanism includes a transparent positioning slit 106 formed on the bracket body 1, and a positioning piece 301 fixed to the preset position of the bumper 3. The width of the positioning slit 106 is adapted to the thickness of the positioning piece 301, so that the positioning piece 301 can pass through the positioning slit 106, and the positioning slit 106 and the positioning piece 301 can be clearance-matched, and the preferred clearance is 0.1mm. The coordination of the positioning slit 106 and the positioning piece 301 can make the positioning structure have fewer degrees of freedom and more accurate positioning. In this embodiment, two groups of matching positioning slits 106 and positioning pieces 301 are arranged so that each group of positioning mechanisms shares the force and improves the durability of the mounting structure.

[0061] In addition, in order to improve the strength and rigidity of the positioning structure, a pair of reinforcing ribs 107 extending upward are respectively provided on the bracket body 1 on the opposite side of the positioning slit 106; when the positioning piece 301 is inserted into the positioning slit 106, the two reinforcing ribs 107 are clamped on both sides of the positioning piece 301 in the thickness direction. The gap between each pair of reinforcing ribs 107 can be consistent with the width of the positioning slit 106, or it can be gradually reduced in the direction of extending upward to form a tighter holding force on the positioning piece 301. The reinforcing ribs 107 on the opposite side of the positioning slit 106 can clamp the positioning piece 301 to prevent the positioning piece 301 from being bent and damaged.

[0062] In order to further protect the radar module 2 and prevent the radar alarm from malfunctioning due to mud and sand blocking, a protective cover 4 is provided on the bracket body 1 and is connected to the bracket body 1 to accommodate the radar module 2. A preferred embodiment, as Fig. 9 As shown, the shield body of the protective cover 4 of this embodiment is configured to have a recessed space to accommodate the radar module 2. When the vehicle bumps, the radar module 2 is effectively prevented from contacting the shield body. The protective cover 4 is preferably snap-fitted with the bracket body 1 for easy installation and fixation. Therefore, the protective cover 4 is provided with a snap hole 402, and the bracket body 1 is provided with a snap hook 109 to cooperate with it. Figure 2 As shown. The protective cover 4 is provided with a positioning hole 401, and the bracket body 1 is provided with a positioning pin 108 adapted to the positioning hole 401. The bracket body 1 may also be provided with a limiting portion 110, which forms a limiting support for the protective cover 4, so that the fixing of the protective cover 4 and the bracket body 1 is more secure. The limiting portion 110 of this embodiment includes an annular boss and a convex rib provided around the positioning pin 108. The convex rib can be used to limit the support of the protective cover 4 and also to improve the strength of the positioning pin 108. Figure 2 and Fig.10 shown.

[0063] In order to improve the heat dissipation of the radar module 2, Fig.11 and Fig.12 As shown, a heat dissipation gap (7) is formed between the bottom edge of the protective cover 4 and the bracket body 1. The heat generated by the radar module 2 can be dissipated to extend the service life of the radar module 2, and the condensed dew can be discharged to make the radar module 2 more durable. In addition, in order to facilitate mechanical automation production, the bracket body 1 is provided with a gripping structure 111 for a robot arm to grip the bracket. In the assembly process, the robot arm can transfer the bracket body 1 through the gripping structure 111.

[0064] When assembling the radar module mounting bracket of this embodiment, the radar module 2 can be first fixed on the bracket body 1, such as Figure 3 As shown, the bracket body 1 is then aligned with the installation position on the bumper 3 through the positioning mechanism, the main body of the mounting bracket is pre-fixed by the adhesive portion 105, and the bracket body 1 is further firmly fixed on the bumper 3 by welding, as shown in FIG. Figure 7 As shown, the protective cover 4 is then buckled and connected to the bracket body 1 to complete the assembly. Figure 5 shown.
