[0002] With the development of intelligent driving technology, the application of radar in vehicles is becoming more and more common. For example, lidar can greatly improve the reliability of the autonomous driving system and enhance driving safety through the effective deployment of radar.

[0003] Radar installation typically requires a wide field of view, and is therefore typically installed overhead. Installing the radar in this area requires meeting the vehicle's exterior quality requirements. In the current structure, the perimeter of the vehicle's front window has an interference fit with the exterior trim. Radar vibrations are transmitted to the exterior trim, causing vibrations and affecting the installation accuracy, which in turn affects the exterior quality. Approximately 30% of noise, vibration, and harshness (NVH) energy is also transmitted to the vehicle body, impacting the user experience.

[0004] Therefore, it is urgent to solve the problem that the installation of radar on the top of the car causes large vibrations and affects the appearance quality. Utility Model Content

[0054] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0055] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, unless otherwise specified, "multiple" means two or more.

[0056] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to changes in the orientation of the components in the drawings.

[0057] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integrated connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0058] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0059] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0060] When the lidar is working, it uses the antenna to emit electromagnetic waves, continuously detects the echoes reflected by obstacles in front or behind, and performs comprehensive analysis through the radar signal processor to calculate the relative speed and distance to the obstacles in front or behind, and generates warning information to transmit to the vehicle control circuit. The vehicle control circuit controls the vehicle's transmission and brakes to take corresponding actions to avoid collisions.

[0061] During the operation of the LiDAR, its internal motor will generate continuous vibration. In the existing technology, the installation of the LiDAR is usually interference fit with the exterior trim around the front window. The vibration generated during the operation of the radar will be transmitted to the exterior trim, thereby driving the exterior trim to vibrate, resulting in about 30% of the noise, vibration and harshness (NVH) energy being transmitted into the vehicle and ultimately transmitted to the human ear. This transmission of vibration and noise will lead to a decline in the vehicle's noise, vibration and harshness (NVH) performance, and have a negative impact on the comfort of the driver and passengers.

[0062] Furthermore, the radar is softly screwed onto the bracket via a vibration isolator. The compression of the isolator's rubber sleeve varies with the torque of the bolts and the physical properties of the rubber sleeve, which makes it difficult to match the front window with the exterior trim. Although some mass-produced models already meet the required tolerances around the front window, when adjusting the compression and physical properties of the isolator's rubber sleeve during actual vehicle calibration, it is necessary to find a balance point to achieve a fixed distance after compression so that the tolerances around the front window meet the requirements. However, this method requires finding a balance point during actual vehicle calibration, which is a complex and difficult to control process. In addition, the existing technology places high demands on the position of the fixing holes on the vehicle body beam to ensure installation accuracy.

[0063] In this application, the radar is rigidly connected to the bracket, the bracket is connected to the outside of the vibration isolator, and the vibration isolator is fixed to the vehicle body crossbeam through the flexible parts in the vibration isolator and the connecting parts are screwed together. The vibration noise of the vehicle body crossbeam only needs to be decoupled from the compression of the vibration isolator by adjusting the physical properties of the vibration isolator rubber sleeve. The tolerance around the front window and the exterior trim only needs to lock the longitudinal position direction of the bracket and the rubber sleeve in the vibration isolator.

[0064] The radar installation structure, radar assembly, and vehicle provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings:

[0065] refer to Figure 1 and Figure 2 As shown, in the first aspect, an embodiment of the present application provides a radar mounting structure, including: a bracket 10, a vibration isolator 30 and a flexible member 40, the bracket 10 is used to rigidly connect the radar 20; the vibration isolator 30 has a connecting hole 31 inside, and the bracket 10 is connected to the outside of the vibration isolator 30; the flexible member 40 is formed in the connecting hole 31; the vibration isolator 30 is connected to the vehicle body cross beam 80 through a connecting member 50 that passes through the vehicle body cross beam 80 and the inside of the flexible member 40.

[0066] The present invention provides a radar mounting structure, which helps to absorb and isolate vibrations through the vibration isolator 30, and can prevent the excitation vibration of the radar 20 itself from being transmitted to the vehicle body cross beam 80. The flexible part 40 is formed in the connecting hole 31. The flexible part 40 can play a role in buffering and absorbing vibrations, and can also effectively prevent the excitation vibration of the radar 20 itself from being transmitted to the vehicle body cross beam 80, thereby preventing the vibration from being transmitted to the passenger compartment, thereby improving the comfort of the ride.

[0067] In addition, since the bracket 10 is used to rigidly connect the radar 20, for example, the bracket 10 and the radar 20 can be connected by screws or bolts, so that the stability of the fixation of the radar 20 relative to the bracket 10 is better. After the exterior trim 70 is fixed to the radar 20, the accuracy of the fixed position of the exterior trim 70 is improved, which is conducive to reducing the difficulty of matching the position of the exterior trim 70 with the front window of the vehicle body. The appearance matching of the exterior trim 70 and the radar 20 can be achieved through their own accuracy. Figure 3 and Figure 4 As shown, the accuracy of at least three positions, namely, the flushness boundary 101 between the exterior trim and the front baffle, the flushness boundary 102 between the radar and the exterior trim, and the flushness boundary 103 between the exterior trim and the skylight glass, is improved, thereby ensuring the quality of the exterior appearance.

[0068] Compared with the structure in which the bracket 10 is softly connected to the radar 20, the radar mounting structure provided in the present application will not be affected by the vibration buffering effect occurring at the connection position between the bracket 10 and the radar 20, thereby improving the accuracy of fixing the exterior trim 70, thereby solving the problems of step differences and gaps that are prone to occur between the exterior trim 70 and the front window of the vehicle body.

[0069] The vehicle body cross beam 80 is a solid part of the vehicle structure, capable of bearing the weight of the mounting structure and external forces, and provides basic support for the radar mounting structure provided in this application.

[0073] The connecting part 50 and the flexible part 40 are sealed and screwed together to connect the vibration isolator 30 to the vehicle body cross beam 80, and waterproof glue is applied to the threaded contact surface between the flexible part 40 and the connecting part 50 to ensure the water-insertion isolation effect between the vibration isolator 30 and the waterproof pad 60, achieving the effect of vibration isolation, waterproofing and dustproofing, and ensuring the reliability of use and the appearance quality.

[0074] In addition, the waterproof pad 60 can also absorb some vibration and impact, reducing the transmission of vibration energy. The material of the waterproof pad 60 should have excellent waterproofness, durability and anti-aging properties.

The connecting shaft 51 is passed through the fixing hole and the connecting hole 31 inside the vibration isolator 30, and the head 52 abuts against the vehicle body cross beam 80, thereby connecting the vibration isolator 30 to the vehicle body cross beam 80 through the connecting piece 50.

[0079] In some embodiments of the present application, the embedded portion 41 may be cylindrical.

[0080] In some embodiments of the present application, the flexible member 40 further includes a flange portion 42 , which is connected to one end of the embedded portion 41 and covers at least a portion of a surface of the vibration isolator 30 facing the vehicle body cross beam 80 .

[0082] In some embodiments of the present application, the radar mounting structure further includes a waterproof pad 60, which is disposed between the vibration isolator 30 and the vehicle cross member 80. The waterproof pad 60 has a mounting hole formed therein, through which the connecting shaft 51 is inserted. This structure not only facilitates the installation of the waterproof pad 60 but also enhances the waterproofing effect of the waterproof pad 60, preventing water from seeping downward into the vehicle body through the fixing holes provided in the vehicle cross member 80.

[0083] In some embodiments of the present application, the mounting hole may be a circular through hole, and the mounting hole may be located at the center of the waterproof pad 60 .

[0084] In the present application, the waterproof pad 60 and the vibration isolator 30 may not be arranged on the lower side of the radar, for example, they may be arranged around the radar, so that the embodiment of the present application provides a radar installation structure with small vertical space requirements, compact shape, and optimized design of radar exterior parts to reduce wind noise.
