Technical Field
[0001] This utility model belongs to the technical field of automotive front bumper structure, and in particular relates to an installation mechanism for automotive millimeter-wave radar. Background Technology
[0002] Millimeter-wave radar is a radar system that operates in the millimeter-wave band (typically referring to the 30–300 GHz frequency range, with wavelengths of 1–10 mm). Millimeter-wave radar transmits electromagnetic waves through an antenna; these waves are reflected back when they encounter a target. The radar receives these reflected waves and uses signal processing techniques to calculate information such as the object's distance, velocity, angle, and azimuth. In this process, the Doppler effect is used to detect the speed of moving objects.
[0003] Millimeter-wave radar is widely used in advanced driver assistance systems (ADAS) and autonomous driving in automobiles due to its advantages such as high resolution, all-weather and all-time operation, strong anti-interference ability, small size and light weight. Moreover, it is a non-contact sensor that can perform measurements without contacting the target. It provides drivers with multiple intelligent driving assistance functions and improves driving safety and comfort.
[0004] Current technology mounts millimeter-wave radar on the inside of the front bumper. This necessitates disassembling the entire front bumper when replacing it, requiring the removal of numerous parts around the bumper, resulting in poor maintainability. Furthermore, in automotive assembly processes, the installation steps for millimeter-wave radar are limited to first installing it on the front bumper, and then installing the bumper onto the vehicle. This restricts the flexibility of process design and increases the difficulty of accurately detecting the installation position of the millimeter-wave radar. Utility Model Content
[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an installation mechanism for automotive millimeter-wave radar, which solves the problems of poor maintainability of millimeter-wave radar, limited flexibility in automotive installation process design, and increased difficulty in detecting the accuracy of millimeter-wave radar installation position in the prior art, where millimeter-wave radar is installed on the inside of the front bumper.
[0006] To achieve the above and other related objectives, this utility model provides an installation mechanism for an automotive millimeter-wave radar, comprising: a front bumper, wherein a mounting groove is formed on the front side of the front bumper, and three positioning posts are fixedly installed on the inner edge of the mounting groove, the three positioning posts being not in a straight line; a millimeter-wave radar, wherein three positioning plates are fixedly connected to the edge of the millimeter-wave radar, and each of the three positioning plates is fixedly connected to one of the positioning posts; a cover plate, wherein a slot is formed on the front side of the front bumper, the slots being distributed on the outer side of the mounting groove, and an insert plate is fixedly installed on the bottom of the cover plate, the insert plate being fitted with a buckle; the insert plate is inserted into the slot, and the buckle engages the slot.
[0007] Optionally, both the positioning post and the positioning plate are provided with threaded holes, and the positioning post and the positioning plate are fixedly connected by screws screwed into the threaded holes.
[0008] Optionally, two positioning posts are disposed at the upper ends inside the mounting groove, and each of the two positioning posts is provided with an upper positioning rib, which abuts against the upper side of the corresponding positioning plate; one positioning post is disposed in the lower middle part inside the mounting groove, and is provided with a lower positioning rib at its lower part, which abuts against the lower side of the corresponding positioning plate.
[0009] Optionally, a left positioning rib is provided on the positioning post at the upper left end inside the mounting groove, and the left positioning rib abuts against the left side of the corresponding positioning plate; a right positioning rib is provided on the positioning post at the upper right end inside the mounting groove, and the right positioning rib abuts against the right side of the corresponding positioning plate.
[0010] Optionally, a limiting block is fixedly installed on the outside of the slot, the insert plate is inserted into the slot, and the bottom of the cover plate abuts against the limiting block.
[0011] As described above, the mounting mechanism for automotive millimeter-wave radar of this utility model has at least the following beneficial effects:
[0012] 1. The mounting mechanism of this automotive millimeter-wave radar features a mounting slot on the front side of the front bumper. Compared to existing technologies that mount the millimeter-wave radar inside the front bumper, this design not only facilitates the disassembly and maintenance of the millimeter-wave radar but also increases the flexibility of automotive assembly process design. Furthermore, three positioning posts are fixedly mounted along the inner edge of this mounting slot. These three positioning posts are not aligned, and positioning plates corresponding to these three positioning posts are fixedly connected to the millimeter-wave radar. The positioning posts and positioning plates are fixedly connected, and the cover plate, through an insert plate, seals the mounting slot. This design ensures that even when mounted on the front side of the front bumper, the millimeter-wave radar remains stable and adequately protected, preventing it from easily detaching from the front bumper or being damaged by a collision.
[0013] 2. The mounting mechanism of this automotive millimeter-wave radar, through the design of the upper and lower positioning ribs, combined with the positioning function of the positioning column and positioning plate, increases the constraint of the millimeter-wave radar installed in the mounting groove and enhances the installation stability of the millimeter-wave radar.

Detailed Implementation
[0019] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.
[0020] Please see Figures 1 to 3 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.
[0021] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.
[0022] Please see Figure 1 and Figure 2 This utility model provides an installation mechanism for a car millimeter-wave radar. Like the prior art, the main body of this installation mechanism also mounts the millimeter-wave radar 2 on the front bumper 1. The difference from the prior art is that the front bumper 1 has a mounting groove 11 on its front side. The millimeter-wave radar 2 is installed in the mounting groove 11, and then the opening of the mounting groove 11 is closed by a cover plate 3. Compared with the prior art design of mounting the millimeter-wave radar 2 on the inside of the front bumper 1, this not only facilitates the disassembly and maintenance of the millimeter-wave radar 2 in the future, but also increases the flexibility of the car assembly process design. That is, it solves the problems of the prior art where the millimeter-wave radar 2 is mounted on the inside of the front bumper 1, resulting in poor maintainability of the millimeter-wave radar 2, limiting the flexibility of the car assembly process design, and increasing the difficulty of detecting the accuracy of the installation position of the millimeter-wave radar 2.
[0023] like Figure 2 and Figure 3 As shown, three positioning posts 12 are fixedly installed on the inner edge of the mounting groove 11, and the three positioning posts 12 are not in a straight line; three positioning plates 21 are fixedly connected to the edge of the millimeter-wave radar 2, and each of the three positioning plates 21 is fixedly connected to one of the positioning posts 12; a slot 13 is also provided on the front side of the front bumper 1, and the slot 13 is distributed on the outer side of the mounting groove 11; an insert plate 31 is fixedly installed on the bottom of the cover plate 3, and a buckle 32 is installed on the insert plate 31; the insert plate 31 is inserted into the slot 13, and the buckle 32 locks the slot 13; thus ensuring that the millimeter-wave radar 2 can remain stable and be adequately protected even when installed on the front side of the front bumper 1, and will not easily fall off the front bumper 1 or be damaged by collision.
[0024] In another implementation, please refer to Figure 2 Both the positioning post 12 and the positioning plate 21 are provided with threaded holes 4. The positioning post 12 and the positioning plate 21 are fixedly connected by screws 5 screwed into the threaded holes 4. When installing the millimeter-wave radar 2, the operator aligns the threaded holes 4 on each positioning plate 21 with the threaded holes 4 on the corresponding positioning post 12, then inserts the screws 5 and screws them into the mounting gun. By screwing the screws 5 in, the millimeter-wave radar 2 can be quickly, conveniently and securely installed into the mounting slot 11.
[0025] In another implementation, please refer to Figure 2Two positioning posts 12 are located at the upper ends inside the mounting groove 11, and each of the two positioning posts 12 has an upper positioning rib 121, which abuts against the upper side of the corresponding positioning plate 21. One positioning post 12 is located in the lower middle part inside the mounting groove 11, and its lower part has a lower positioning rib 122, which abuts against the lower side of the corresponding positioning plate 21. With the help of the threaded hole 4 and the screw 5, the positioning plate 21 and the positioning post 12 increase the constraint of the millimeter-wave radar 2 installed in the mounting groove 11 and strengthen the installation stability of the millimeter-wave radar 2.
[0026] In another implementation, please refer to Figure 2 A left positioning rib 123 is provided on the positioning post 12 at the upper left end inside the mounting groove 11, and the left positioning rib 123 abuts against the left side of the corresponding positioning plate 21; a right positioning rib 124 is provided on the positioning post 12 at the upper right end inside the mounting groove 11, and the right positioning rib 124 abuts against the right side of the corresponding positioning plate 21; based on the previous embodiment, the constraint of the millimeter-wave radar 2 installed in the mounting groove 11 is further increased, and the installation stability of the millimeter-wave radar 2 is strengthened.
[0027] In other implementation methods, such as Figure 2 and Figure 3 As shown, a limiting block 14 is fixedly installed on the outside of the slot 13. The insert plate 31 is inserted into the slot 13, and the bottom of the cover plate 3 abuts against the limiting block 14. The contact surface between the limiting block 14 and the bottom of the cover plate 3 is arc-shaped. The limiting block 14 not only prevents the cover plate 3 from being installed improperly, but also provides a certain buffering effect for the cover plate 3 when the vehicle is driving on a bumpy road, because of the arc-shaped design of the contact surface. That is, it also plays a protective role for the millimeter-wave radar 2.
[0028] In summary, this utility model, with its mounting groove 11 on the front side of the front bumper 1, compared to the prior art's design of mounting the millimeter-wave radar 2 inside the front bumper 1, not only facilitates the later disassembly and maintenance of the millimeter-wave radar 2, but also increases the flexibility of automotive assembly process design. Furthermore, three positioning posts 12 are fixedly mounted on the inner edge of the mounting groove 11. These three positioning posts 12 are not in a straight line, and positioning plates 21 corresponding to these three positioning posts 12 are fixedly connected to the millimeter-wave radar 2. The positioning posts 12 and positioning plates 21 are fixedly connected, and the cover plate 3 closes the mounting groove 11 by inserting a plate 31 into the slot 13. This design ensures that the millimeter-wave radar 2 remains stable and adequately protected even when mounted on the front side of the front bumper 1, preventing it from easily detaching from the front bumper 1 or being damaged by collisions. Therefore, this utility model effectively overcomes the shortcomings of the prior art and has high industrial application value.
[0029] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
