[0039] The terms “including,” “comprising,” or any other variations thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0040] The terms "an embodiment," "as an example," or "in an example," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which may be included in at least one embodiment or example of this application. These illustrative expressions do not necessarily refer to the same embodiment, nor are they independent or alternative embodiments mutually exclusive with other embodiments. Where there is no conflict, the embodiments and features described in these embodiments can be combined in a suitable manner.

[0041] Please see Figure 1 This utility model provides a car, including a roof beam 3 and an on-board radar, with the on-board radar fixed to the roof beam 3.

[0042] Please see Figure 2 The vehicle-mounted radar of this utility model includes a radar decorative cover assembly and a mounting component 31, with the radar decorative cover assembly and the mounting component 31 fixedly connected. Specifically, the radar decorative cover assembly includes a radar body 1 and a decorative cover 2. The radar body 1 is disposed between the decorative cover 2 and the mounting component 31. The radar body 1 is fixedly connected to the decorative cover 2 by at least one connection method selected from fastener connection, snap-fit, and adhesive bonding. The decorative cover 2 is fixedly connected to the mounting component 31 by fastener connection or snap-fit, etc. Optionally, in this embodiment, a portion of the top cover crossbeam 3 forms the mounting component 31.

[0043] During installation, the radar body 1 is first fixedly connected to the decorative cover 2, and then the decorative cover 2 is fixed to the mounting component 31. Compared with fixing the radar body 1 to the mounting component 31 via a bracket, this method is more lightweight, easier to install, and lowers costs. Furthermore, it reduces the number of parts, resulting in a more compact structure and saving space. In addition, when the radar body 1 is fixedly connected to the mounting component 31 via a bracket, mounting holes need to be made on the mounting component 31 for fasteners or hooks to pass through, leading to poor sealing. Fixing the radar body 1 to the mounting component 31 via the decorative cover 2 reduces the number of mounting holes on the mounting component 31, improving the waterproof performance of the vehicle radar.

[0044] Please see Figure 3 and Figure 4 Optionally, a portion of the mounting member 31 is recessed relative to another portion of it in a direction away from the decorative cover 2 to form a receiving cavity 311. The decorative cover 2 covers the area of ​​the corresponding mounting cavity of the mounting member 31. The radar body 1 is located between the decorative cover 2 and the mounting member 31, and is at least partially located within the receiving cavity 311.

[0045] Please see Figure 5In some embodiments, the radar body 1 and the decorative cover 2 are respectively provided with a first fixing part 11 and a second fixing part 21. The first fixing part 11 is fixedly connected to the second fixing part 21 by at least one connection method, namely fastener connection and snap-fit, to fix the radar body 1 to the decorative cover 2. Furthermore, the radar body 1 is fixedly connected to the mounting member 31 through the decorative cover 2. Optionally, the radar body 1 has a first fixing part 11 protruding from its outer surface. The first fixing part 11 is generally plate-shaped and has a through hole for fasteners to pass through. Optionally, there are at least two first fixing parts 11, located on opposite sides of the radar body 1. In one embodiment, there are three first fixing parts 11, and the line connecting the three first fixing parts 11 forms a triangle to improve the stability of the connection.

[0046] Example 1

[0047] In one embodiment, the second fixing part is generally columnar, and the second fixing part has a connecting hole (not shown) along its axial direction. The connecting hole of the second fixing part corresponds to the through hole of the first fixing part 11. The fastener passes through the through hole and the connecting hole in sequence. The inner surface of the connecting hole is provided with an internal thread for threaded connection with the fastener. The first fixing part 11 is fixedly connected to the second fixing part by the fastener, and the radar body 1 is fixed to the decorative cover 2.

[0048] Example 2

[0049] In another embodiment, the second fixing part is generally rectangular, or it can be a U-shaped or L-shaped plate. The second fixing part has a connecting hole. In this example, the fastener is a bolt. The connecting hole of the second fixing part corresponds to the through hole of the first fixing part 11. The bolt passes through the first fixing part 11 and the second fixing part in sequence, and the first fixing part 11 is fixed to the second fixing part by a nut, thereby fixing the radar body 1 to the decorative cover 2.

[0050] Example 3

[0051] Please see Figure 6 In another embodiment, the vehicle-mounted radar of this utility model further includes a fixing member 4, which is snapped into the second fixing part 21 and fixedly connected to the first fixing part 11 by fasteners. Optionally, the projection of the fixing member 4 along the direction parallel to the fixing plate 211 is approximately "I" shaped. Specifically, the fixing member 4 includes a connecting post 43, and the upper and lower parts of the outer periphery of the connecting post 43 are respectively provided with a first mounting plate 41 and a second mounting plate 42 extending radially outward along the connecting post 43, with a gap between the first mounting plate 41 and the second mounting plate 42.

[0052] Please combine Figure 7 and Figure 8Furthermore, the second fixing part 21 is generally rectangular or trapezoidal shell-shaped. Specifically, the portion of the decorative cover 2 corresponding to the first fixing part 11 protrudes relative to its other portion to form the second fixing part 21. The second fixing part 21 includes a placement cavity formed by the side plate 212 and the fixing plate 211, for accommodating the second mounting plate 42. The side plate 212 has an opening 21a for the second mounting plate 42 to pass through the placement cavity. The fixing plate 211 has a mounting groove 21b communicating with the placement cavity and communicating with the opening 21a. The connecting post in the space is inserted into the mounting groove 21b. When the fixing member 4 is installed in the second fixing part 21, the first mounting plate 41 and the second mounting plate 42 are located outside and inside the fixing plate 211, respectively. Optionally, the width of at least part of the mounting groove 21b gradually decreases in the direction away from the opening 21a, which is beneficial for guiding the fixing member 4 to slide into the mounting groove 21b.

[0053] Optionally, the connecting post 43 has a through connecting hole 44 along its axial direction for fasteners to pass through. The fasteners can be bolts. The inner surface of the connecting hole 44 has internal threads. The bolt passes through the through hole of the first fixing part 11 and the connecting hole 44 of the second fixing part 21 in sequence, and is threadedly connected to the fixing member 4 to improve the connection stability.

[0054] Optionally, the second fixing part 21 protrudes from the surface of the fixing plate 211 toward the first fixing part 11 to form an abutment edge 211a. The first fixing part 11 abuts against the abutment edge 211a and is fixedly connected to the second fixing part 21 by the fixing member 4, thereby limiting the relative position of the fixing member 4 and the second fixing part 21 along the height direction of the vehicle and further improving the connection stability. Optionally, a first reinforcing rib 215 is provided between the second fixing part 21 and the inner surface of the decorative cover 2 to improve the connection strength and connection reliability.

[0055] In one embodiment, the second fixing part 21 is further provided with a limiting strip 213, which is made of an elastic material such as plastic or metal. Specifically, the second fixing part 21 protrudes from the surface of the opening 21a toward the mounting groove 21b to form the limiting strip 213. Further, the protrusion of the limiting strip 213 near the surface of the first fixing part 11 forms a limiting protrusion 214, which is used to limit the relative position of the fixing member 4 and the second fixing member 4, thereby improving the stability of the connection.

[0056] During installation, the fastener 4 passes through the opening 21a of the second fixing part 21 and can press the limiting protrusion 214, causing the limiting strip 213 to deform and accumulate elastic potential energy. The fastener 4 continues to pass through the mounting groove 21b of the second fixing part 21. The limiting strip 213 returns to its initial position due to the elastic force, and the limiting protrusion 214 is located on one side of the fastener 4, which is used to limit the relative position of the fastener 4 and the second fixing part 21 along the length direction of the limiting strip 213.

[0057] Please continue reading. Figure 6 and Figure 7 In some embodiments, one of the radar body 1 and the decorative cover 2 is provided with a hook 221, and the other is provided with a snap-fit ​​plate 12. The hook 221 snaps into the snap-fit ​​plate 12 to define the relative position of the radar body 1 and the decorative cover 2 along the height direction of the vehicle. In one embodiment, the snap-fit ​​plate 12 is provided on the side of the radar body 1, and the hook 221 is provided on the decorative cover 2. Optionally, the decorative cover 2 is also provided with a mounting base 22, the hook 221 is provided on the surface of the mounting base 22, and a second reinforcing rib 223 is provided between the hook 221 and the mounting base 22 to improve the connection strength and reliability.

[0058] In one embodiment, one of the radar body 1 and the decorative cover 2 is provided with a limiting plate 222, and the other is provided with a limiting block 13. The limiting plate 222 and the limiting block 13 abut against each other to limit the relative position of the radar body 1 and the decorative cover 2 along the width direction of the vehicle. Optionally, the snap-fit ​​plate 12 protrudes from its surface away from the radar body 1 to form the limiting block 13, and the limiting block 13 is provided on the surface of the mounting base 22. Optionally, there are two limiting plates 222 and two limiting blocks 13. The two limiting plates 222 are spaced apart on the inner surface of the decorative cover 2, that is, the surface of the decorative cover 2 near the radar body 1. The two limiting blocks 13 cooperate with the two limiting plates 222 respectively to improve the installation accuracy.

[0059] Please see Figure 2 In some embodiments, the mounting member 31 has a mounting hole 312 for the connector to pass through. The connector is pre-fixed to the decorative cover 2 by means of snap-fit ​​or threaded connection. The decorative cover 2 is fixedly connected to the mounting member 31 by the connector.

[0060] Please see Figure 5 Optionally, the inner surface of the decorative cover 2 is provided with a number of positioning posts 23, and the mounting part 31 is provided with positioning holes 313 for the positioning posts 23 to pass through. During installation, the positioning posts 23 are inserted into the positioning holes 313 for easy installation.

[0061] Please continue reading. Figure 5 In some embodiments, at least one of the decorative cover 2 and the mounting member 31 is provided with a waterproof rib 14, which is located between the decorative cover 2 and the mounting member 31 to prevent liquid from seeping into the receiving cavity 311. Optionally, the waterproof rib 14 is provided at the edge of the decorative cover 2. Specifically, the waterproof rib 14 protrudes from the inner surface of the decorative cover 2, or a part of the decorative cover 2 protrudes relative to another part to form the waterproof rib 14. The waterproof rib 14 can also be provided in the corresponding portion of the receiving cavity 311 of the mounting member 31. When driving in the rain or washing the vehicle, the waterproof rib 14 can prevent liquid from flowing into the receiving cavity 311, thereby improving the waterproof performance of the vehicle radar.

[0062] Please combine Figure 9 In one embodiment, the vehicle-mounted radar further includes a waterproof component 5, which is made of materials such as foam, rubber, or sealant. The waterproof component 5 is sandwiched between the decorative cover 2 and the mounting member 31. Optionally, the waterproof component 5 is fitted into the area of ​​the corresponding receiving cavity 311 of at least one of the decorative cover 2 and the mounting member 31. Optionally, the waterproof component 5 is attached to the decorative cover 2 by means of adhesive bonding, fastener connection, etc., for easy installation. Specifically, the thickness of the waterproof component 5 is greater than the height of the waterproof rib 14, so that the waterproof component 5 can be sandwiched between the decorative cover 2 and the mounting member 31. The opposite sides of the waterproof component 5 abut against the decorative cover 2 and the mounting member 31 respectively, improving the sealing between the decorative cover 2 and the mounting member 31, preventing liquid from entering the interior of the decorative cover 2, and further improving the waterproof performance of the vehicle-mounted radar.

[0063] Please combine Figure 4 The top cover beam 3 extends along the width of the vehicle and tilts downward in the direction of the front of the vehicle. The mounting part 31 is tilted downward in the direction of the front of the vehicle. When liquid seeps into the receiving cavity 311, the downward tilt of the mounting part 31 in the direction of the front of the vehicle can guide the direction of liquid flow, thereby draining the liquid in the receiving cavity 311.

[0064] Please continue reading. Figure 9 In one embodiment, the waterproof component 5 includes a first waterproof strip 51 and two second waterproof strips 52. The first waterproof strip 51 and the two second waterproof strips 52 are sequentially and spaced apart around the receiving cavity 311 of the mounting member 31, and the first waterproof strip 51 and the second waterproof strip 52 are respectively located on opposite sides of the receiving cavity 311 along the front-rear direction of the vehicle. Specifically, the projection of the first waterproof strip 51 along its thickness direction is approximately an inverted "U" shape. There is a gap between the ends of the two second waterproof strips 52 that are close to each other, which forms a first drain outlet 5a. The ends of the two second waterproof strips 52 that are away from each other are respectively disposed corresponding to the ends of the first waterproof strip 51, and there is a gap between the second waterproof strip 52 and the first waterproof strip 51, which forms a second drain outlet 5b. A small amount of liquid that seeps into the receiving cavity 311 can flow from the surface of the mounting member 31 to the first drain outlet 5a and the second drain outlet 5b and be discharged, preventing liquid from accumulating inside the receiving cavity 311 and improving the drainage effect.

[0065] Optionally, the waterproof component 5 further includes a third waterproof strip 53. The portion of the mounting member 31 near the first drain outlet 5a protrudes relative to its other portion in the direction close to the waterproof component 5, forming a waterproof boss 315. The third waterproof strip 53 is disposed on the waterproof boss 315. The third waterproof strip 53 extends approximately in the left-right direction of the vehicle, and its length is greater than the width of the first drain outlet 5a; that is, the projection of the third waterproof strip 53 along its width direction coincides with the ends of both second waterproof strips 52. Further, there is a gap between the third waterproof strip 53 and the two second waterproof strips 52, forming a flow channel 5c. This flow channel communicates with the first drain outlet 5a, forming a "T"-shaped drainage channel. The waterproof boss 315 and the "T"-shaped drainage channel facilitate the discharge of liquid that has seeped into the receiving cavity 311, and prevent liquid from flowing into the receiving cavity 311 from the first drain outlet 5a. In scenarios such as driving in the rain or washing the vehicle, the waterproof component 5 can prevent most liquid from entering the receiving cavity 311 from the contact position between the decorative cover 2 and the mounting part 31. When a small amount of water seeps into the receiving cavity 311, the mounting part 31 is tilted downwards in the direction of the front of the car, and cooperates with the first drain port 5a and the second drain port 5b to guide the liquid that has seeped into the receiving cavity 311 to be discharged along the surface of the mounting part 31 through the first drain port 5a and the second drain port 5b.

[0066] Please see Figure 2 In some embodiments, the vehicle-mounted radar of this invention further includes a wiring harness 6 and a wiring harness sheath 61. The mounting member 31 has a wiring harness through-hole 314 for the wiring harness 6 to pass through. A portion of the wiring harness 6 passes through the wiring harness sheath 61 and is fixed to the wiring harness through-hole 314 by the wiring harness sheath 61, improving the sealing at the wiring harness through-hole 314, thereby preventing liquid from seeping into the vehicle body and further improving waterproof performance. In addition, the vehicle-mounted radar of this invention also includes a sealing gasket, which is provided corresponding to the mounting hole 312 and sandwiched between the connector and the mounting member 31, thereby preventing liquid from entering the vehicle body and improving the waterproof performance of the vehicle-mounted radar.
