Description

[0001] Technical Field: This utility model discloses a millimeter-wave radar mounting structure for automotive trim panels and a vehicle having the same structure, belonging to the technical field of vehicle millimeter-wave radar. Background Technology

[0002] During vehicle operation, the environment is extremely complex and challenging, and vibration and impact are unavoidable. When a car is driving on the road, the unevenness of the road surface varies greatly, from gravel roads to bumpy sections full of potholes and speed bumps, all of which will cause the vehicle to vibrate to varying degrees.

[0003] For millimeter-wave foot-activated radar installed on vehicle trim panels, it acts like a smart "gatekeeper." By accurately capturing and authenticating the driver's approach, the millimeter-wave radar can quickly recognize preset actions, reacting rapidly to everything from a light step to a simple kick, thus automatically opening and closing the doors and greatly enhancing the user experience. However, because vehicles are subjected to repeated vibrations and impacts during continuous driving, without effective limiting measures, the millimeter-wave foot-activated radar is like a fragile object, easily displaced by these external forces. Once displaced, the radar's sensing accuracy is greatly reduced, potentially failing to accurately recognize the driver's actions, causing the doors to malfunction and preventing proper opening or closing. This not only causes significant inconvenience to the driver but may also pose a safety hazard in emergency situations. Utility Model Content

[0004] The purpose of this invention is to solve the problem of poor stability of existing millimeter-wave radar mounting structures, and to propose a millimeter-wave radar mounting structure for automotive trim panels and a vehicle having the same structure.

[0005] The problem to be solved by this utility model is achieved by the following technical solution: A millimeter-wave radar mounting structure for an automotive trim panel includes: an automotive trim panel having a mounting portion located at the center of the inner side of the trim panel; a millimeter-wave radar assembly having one side embedded in the mounting portion; and bolts for connecting the millimeter-wave radar assembly to the mounting portion.

[0006] Furthermore, the installation unit includes: an installation platform, which is located in the middle of the inner side of the automotive trim panel; two positioning screw holes, which are spaced apart about the installation platform; two bolts, which are threadedly engaged with the two bolts; and two cross-shaped positioning posts, which are spaced apart about the installation platform, with the cross-shaped positioning post on either side of the installation platform adjacent to the positioning screw holes.

[0007] Furthermore, the millimeter-wave radar assembly includes: a millimeter-wave radar housing with a mounting cavity, the millimeter-wave radar housing being embedded in two cross-shaped positioning posts; a PCB assembly disposed within the mounting cavity; and double-sided adhesive tape disposed between the millimeter-wave radar housing and the mounting platform, the double-sided adhesive tape being used to connect the millimeter-wave radar housing and the mounting platform.

[0008] Furthermore, the millimeter-wave radar housing includes: a lower housing of the millimeter-wave radar, which has a mounting cavity and a first positioning hole and a second positioning hole on each side; and an upper housing of the millimeter-wave radar, which is fastened to the top opening of the upper housing of the millimeter-wave radar; wherein, the bolt passes through the first positioning hole and engages with the positioning screw hole, and the second positioning hole is fitted onto the cross positioning post.

[0009] Furthermore, the PCB assembly includes: a PCB board and multiple PCB bolts. Multiple limiting holes are provided on the PCB board near the edge.

Detailed Implementation

[0020] The following is based on the appendix Figure 1-6 Further explanation of this utility model: The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1 As shown, the first embodiment of this utility model provides a car trim panel millimeter-wave radar mounting structure based on the prior art, including: a car trim panel 1, a millimeter-wave radar component 2 and bolts 3. The car trim panel 1 is provided with a mounting part, which is arranged in the middle of the inner side of the car trim panel 1. One side of the millimeter-wave radar component 2 is embedded in the mounting part, and the bolts 3 are used to connect the millimeter-wave radar component 2 to the mounting part.

[0024] By placing the mounting part in the middle of the inner side of the automotive trim panel 1 in this embodiment, the uneven distribution of force can minimize the excessive local stress caused by uneven force distribution, thereby reducing the risk of the millimeter-wave radar loosening or being damaged due to uneven force. The embedded design can provide precise positioning for the millimeter-wave radar component 2, making it fit tightly with the mounting part. The bolt 3 firmly connects the millimeter-wave radar component and the mounting part together through the preload generated by tightening. In the vibration environment of long-term vehicle operation, it can effectively prevent the bolt from gradually loosening due to vibration, ensuring the reliability and stability of the connection.

[0025] like Figure 2 As shown, the mounting part includes: a mounting platform 12, two positioning screw holes 11 and two cross positioning posts 13. The mounting platform 12 is located in the middle of the inner side of the car trim panel 1. The two positioning screw holes 11 are spaced apart about the mounting platform 12. There are two bolts 3. The two positioning screw holes 11 are threadedly engaged with the two bolts 3. The two cross positioning posts 13 are spaced apart about the mounting platform 12. The cross positioning posts 13 on any side of the mounting platform 12 are arranged adjacent to the positioning screw holes 11.

[0026] The two cross-shaped locating posts 13, spaced apart from the mounting platform 12, provide an accurate positioning reference for the millimeter-wave radar assembly 2. During installation, the radar assembly, in conjunction with the cross-shaped locating posts, can quickly and accurately determine its position on the mounting platform, ensuring installation accuracy and consistency. This facilitates accurate environmental perception by the millimeter-wave radar and avoids detection errors caused by installation position deviations. The locating screw holes 11 and bolts 3 are threaded together, a simple connection method that facilitates installation and disassembly. During installation, simply pass the bolt through the corresponding hole on the millimeter-wave radar assembly and screw it into the locating screw hole to complete the fixation; during disassembly, unscrewing the bolt allows for easy removal of the radar assembly, improving installation and maintenance efficiency. The arrangement of the two locating screw holes 11 and two bolts 3, along with the adjacent arrangement of the cross-shaped locating posts 13 and locating screw holes 11, makes the millimeter-wave radar assembly more securely fixed on the mounting platform. Multiple fixing points can evenly distribute various forces, such as vibration and impact, experienced by the radar assembly during vehicle operation, reducing the possibility of loosening or displacement of the radar assembly and ensuring long-term stable operation of the radar.

[0027] like Figure 3-6 As shown, the millimeter-wave radar assembly 2 includes: a millimeter-wave radar housing, a PCB assembly 24, and double-sided adhesive tape 23. The millimeter-wave radar housing is provided with a mounting cavity and is embedded in two cross-shaped positioning posts 13. The PCB assembly 24 is disposed in the mounting cavity. The double-sided adhesive tape 23 is disposed between the millimeter-wave radar housing and the mounting platform 12 and is used to connect the millimeter-wave radar housing and the mounting platform 12.

[0028] Double-sided adhesive tape 23 connects the millimeter-wave radar housing to the mounting platform 12. In addition to the bolts 3, this extra connection provides double fixation, making the connection between the millimeter-wave radar housing and the mounting platform tighter and more stable, effectively preventing the radar from loosening due to vibration during vehicle operation. The double-sided adhesive tape 23 has a certain degree of elasticity and flexibility, acting as a buffer and shock absorber between the millimeter-wave radar housing and the mounting platform. It can absorb some of the vibration energy generated during vehicle operation, reducing the impact of vibration on precision components such as the internal PCB assembly 24 of the millimeter-wave radar, thus helping to protect the radar's performance and extend its service life.

[0029] Furthermore, the millimeter-wave radar housing includes: a lower housing 21 and an upper housing 22. The lower housing 21 has a mounting cavity. A first positioning hole 211 and a second positioning hole 212 are respectively provided on both sides of the lower housing 21. The upper housing 22 is fastened to the top opening of the upper housing 22. The bolt 3 passes through the first positioning hole 211 and is threaded into the positioning screw hole 11. The second positioning hole 212 is fitted onto the cross positioning post 13.

[0030] The lower housing 21 and upper housing 22 of the millimeter-wave radar are connected by a snap-fit ​​mechanism. During installation, simply snap the upper housing onto the opening at the top of the lower housing, and then secure the lower housing to the mounting section with bolts. This simple operation improves assembly efficiency and reduces assembly difficulty. The lower housing of the millimeter-wave radar has a mounting cavity to accommodate internal components such as PCB assemblies. The upper housing 22 snaps onto the lower housing 21, forming a closed space that provides excellent protection for the internal components, preventing dust, moisture, and debris from entering. This avoids interference and damage to the internal components from external factors, helping to extend the service life of the millimeter-wave radar.

[0031] The PCB assembly 24 includes a PCB board 241 and multiple PCB bolts 243. Multiple limiting holes 2411 are provided on the PCB board 241 near its edge. Circuit board positioning screw holes 213 are provided inside the millimeter-wave radar lower housing 21. The multiple PCB bolts 243 pass through the limiting holes 2411 and are threaded into the circuit board positioning screw holes 213. By engaging the limiting holes 2411 on the PCB board 241 with the circuit board positioning screw holes inside the millimeter-wave radar lower housing 21, the position of the PCB board 241 within the millimeter-wave radar lower housing 21 can be accurately defined, ensuring its installation accuracy. This maintains the accurate relative positions of the various electronic components on the PCB board 241 with other components, which is beneficial for the signal transmission and processing of the millimeter-wave radar and improves the performance stability of the radar.

[0032] Furthermore, the PCB assembly 24 also includes a PCB cover 242, which is attached to the side of the PCB board 241 away from the upper housing 22 of the millimeter-wave radar. The PCB cover 242 provides electromagnetic shielding, reducing the impact of external electromagnetic interference on the electronic components on the PCB board 241. It also prevents electromagnetic waves generated by the electronic components on the PCB board 241 from interfering with other external devices, improving the electromagnetic compatibility of the millimeter-wave radar and ensuring its performance stability and reliability. The PCB cover 242, in conjunction with the PCB board 241, increases the overall structural strength and stability of the PCB assembly. During vehicle operation, when the millimeter-wave radar is subjected to vibration or impact, the PCB cover 242 helps to disperse stress, reducing the possibility of deformation or damage to the PCB board 241, allowing the PCB assembly to better adapt to complex working environments.

[0033] In one exemplary embodiment, a reinforcing rib 213 is provided on the inner side of the lower housing 21 of the millimeter-wave radar. The reinforcing rib 213 can increase the thickness and rigidity of the lower housing 21 of the millimeter-wave radar, making it less prone to deformation or damage when subjected to external impact or vibration, thereby protecting the internal precision components such as PCB assemblies and ensuring that the millimeter-wave radar can work stably during vehicle operation.

[0034] The second embodiment of this utility model provides a vehicle based on the first embodiment, including a millimeter-wave radar mounting structure for automotive trim panels, wherein the millimeter-wave radar mounting structure for automotive trim panels is the aforementioned millimeter-wave radar mounting structure for automotive trim panels.
