[0034] Please refer to Figure 1 The present embodiment provides a radar device 100, including a housing 110 and an antenna assembly 120 located in the housing 110, wherein the antenna assembly 120 includes a transmitting antenna 121 and a receiving antenna 122, and the transmitting antenna 121 and the receiving antenna 122 are spaced apart and distributed on opposite sides of the housing 110.

[0035] Specifically, Figure 1 As shown, the present application provides a radar device 100, which includes an antenna assembly 120 and a housing 110. Preferably, in order to reduce the weight of the radar device 100, the housing 110 is made of plastic material; compared with the existing radar antenna exposed to the outside, the radar device 100 provided by the present application places the antenna assembly 120 in the housing 110, and the housing 110 can provide a certain protection effect for the antenna assembly 120, preventing rain from falling on the antenna assembly 120 when it rains and causing a short circuit of the radar device 100.

[0036] The antenna assembly 120 includes a transmitting antenna 121 and a receiving antenna 122 , and the transmitting antenna 121 and the receiving antenna 122 are spaced apart and distributed on opposite sides of the housing 110 , so as to improve the space utilization of the housing 110 , thereby realizing the miniaturization and lightweight of the radar device 100 .

[0037] The present application provides a radar device 100, including a housing 110 and an antenna assembly 120 located in the housing 110, wherein the antenna assembly 120 includes a transmitting antenna 121 and a receiving antenna 122, and the transmitting antenna 121 and the receiving antenna 122 are spaced apart and distributed on opposite sides of the housing 110. The radar device 100 can realize the miniaturization of the device, reduce the overall weight, and provide protection for the radar, thereby extending the service life of the radar device 100.

[0038] In one possible implementation manner of the present application, the antenna assembly 120 further includes a processing unit 123 , and the transmitting antenna 121 and the receiving antenna 122 are electrically connected to the processing unit 123 , respectively.

[0039] Specifically, the transmitting antenna 121 and the receiving antenna 122 are electrically connected to the processing unit 123 respectively, and the processing unit 123 can process the received signals to achieve target detection and identification; the shell 110 can provide a certain protection effect for the transmitting antenna 121, the receiving antenna 122 and the processing unit 123, further improving the reliability and service life of the radar device.

[0040] For example, the processing unit 123 is located between the transmitting antenna 121 and the receiving antenna 122, so that the transmitting antenna 121 and the receiving antenna 122 can be electrically connected to the processing unit 123 respectively, making the layout of the components in the housing 110 more reasonable.

[0041] Optionally, the processing unit 123 is located at the center line connecting the transmitting antenna 121 and the receiving antenna 122, so that the antenna assembly 120 has an I-shaped structure. Such a setting can further reduce the volume of the antenna assembly 120 and realize the miniaturization of the radar device 100.

[0042] In one possible implementation of this application, please refer to Figure 1 and Figure 4 The shell 110 includes a front shell 111 and a rear shell 112, and the antenna assembly 120 is fixed to the inner wall of the rear shell 112; the inner wall of the rear shell 112 is provided with a plurality of reinforcing ribs 113, and the plurality of reinforcing ribs 113 are staggered.

[0043] Specifically, please refer to Figure 1 and Figure 4The housing 110 includes a front housing 111 and a rear housing 112 that are screwed together, and the antenna assembly 120 is fixed to the inner wall of the rear housing 112 by bolts to improve the connection stability of the radar device 100. The inner wall of the rear housing 112 is provided with a plurality of reinforcing ribs 113, and the plurality of reinforcing ribs 113 are staggered to increase the overall strength of the housing 110, further improving the reliability and stability of the radar device 100.

[0044] It should be noted that if Figure 1 As shown, first, the reinforcing ribs 113 are staggered to form a plurality of rectangular frames, and the height of the reinforcing ribs 113 in the area of ​​the rear shell 112 where the antenna assembly 120 is arranged is lower than the height of the reinforcing ribs 113 in the remaining areas, so as to play a role in positioning the installation of the antenna assembly 120; the reinforcing ribs 113 around the edge of the antenna assembly 120 are higher, which can better clamp the antenna assembly 120, play a good limiting and fixing effect, prevent the antenna assembly 120 from moving, and further improve the reliability and stability of the radar device 100.

[0045] Second, in order to further improve the strength of the radar device 100 , preferably, the inner wall of the front shell 111 is also provided with reinforcing ribs 113 , and a plurality of reinforcing ribs 113 are staggered.

[0046] For example, Figure 5 As shown, the radar device 100 further includes a metal reinforcing plate 130 , which is disposed on a side of the rear housing 112 facing away from the front housing 111 .

[0047] Specifically, since the radar device 100 is set outdoors all year round, the shell 110 made of plastic material is prone to deformation, and the deformation easily leads to reduced data accuracy of the radar antenna. Therefore, in order to reduce the deformation of the shell 110, the radar device 100 also includes a metal reinforcement plate 130. The metal reinforcement plate 130 is arranged on the side of the rear shell 112 away from the front shell 111. The setting of the metal reinforcement plate 130 can increase the strength of the shell 110, while ensuring the flatness of the shell 110, reducing the deformation of the shell 110, and realizing the auxiliary heat dissipation function of the radar device 100.

[0048] It should be noted that, first, in order to increase the strength of the housing 110 as much as possible, Figure 5 As shown, the metal reinforcing plate 130 is in an I-shaped structure to match the structure of the antenna assembly 120 and can also provide good auxiliary heat dissipation function.

[0049] Second, the metal reinforcing plate 130 is an aluminum alloy plate, which not only has reliable strength, but is also a lightweight metal with good portability, which ensures the strength of the housing 110 while taking into account the miniaturization and lightness of the radar device 100. Of course, in addition to aluminum alloy, the metal reinforcing plate 130 can also be made of other materials that take into account both strength and portability, and this application does not impose any limitation on the specific materials.

[0050] In one possible implementation of the present application, Figure 3 As shown, the front shell 111 is provided with a first wave-transmitting area 1111 and a second wave-transmitting area 1112 , and the orthographic projection of the transmitting antenna 121 on the front shell 111 coincides with the first wave-transmitting area 1111 ; the orthographic projection of the receiving antenna 122 on the front shell 111 coincides with the second wave-transmitting area 1112 .

[0051] Specifically, in order to minimize the signal loss of the plastic material to the antenna assembly 120, as Figure 3 As shown, the front shell 111 is provided with a first wave-transmitting area 1111 and a second wave-transmitting area 1112, and the orthographic projection of the transmitting antenna 121 on the front shell 111 coincides with the first wave-transmitting area 1111, so that the signal transmitted by the transmitting antenna 121 can pass through the first wave-transmitting area 1111 without loss; the orthographic projection of the receiving antenna 122 on the front shell 111 coincides with the second wave-transmitting area 1112, so that the signal received by the receiving antenna 122 can pass through the second wave-transmitting area 1112 without loss.

[0052] By providing the first wave-transmitting area 1111 and the second wave-transmitting area 1112 , the reliability and efficiency of the radar device 100 in receiving and sending signals are improved, and the signal loss is reduced.

[0053] For example, the first wave-transmitting area 1111 is provided with a first opening, the orthographic projection of the transmitting antenna 121 on the front shell 111 coincides with the first opening, and the first opening is covered with a wave-transmitting material; the second wave-transmitting area 1112 is provided with a second opening, the orthographic projection of the receiving antenna 122 on the front shell 111 coincides with the second opening, and the second opening is covered with a wave-transmitting material.

[0054] Specifically, the first wave-transmitting area 1111 is provided with a first opening, the orthographic projection of the transmitting antenna 121 on the front shell 111 coincides with the first opening, and the first opening is covered with a wave-transmitting material, so that the signal transmitted by the transmitting antenna 121 can pass through the wave-transmitting material on the first opening without loss; the second wave-transmitting area 1112 is provided with a second opening, the orthographic projection of the receiving antenna 122 on the front shell 111 coincides with the second opening, and the second opening is covered with a wave-transmitting material, so that the signal received by the receiving antenna 122 can pass through the wave-transmitting material on the second opening without loss. The wave-transmitting material can ensure that the radio frequency electromagnetic wave has little loss and distortion after passing through, further improves the reliability and efficiency of the radar device 100 in receiving and sending signals, reduces the loss of signals, and can also play a certain protective role for the transmitting antenna 121 and the receiving antenna 122.

[0056] Specifically, please refer to Figure 2 and Figure 5 The rear shell 112 is also provided with a mounting hole 1121, and the mounting hole 1121 is used to pass the signal transmission line 140 to achieve the connection between the radar device 100 and the external device. One end of the signal transmission line 140 is connected to the processing unit 123 of the antenna assembly 120, and the other end is connected to the external device to achieve signal transmission.

[0057] In order to improve the reliability of the signal transmission line 140 , a portion of the signal transmission line 140 disposed outside the housing 110 is covered with a waterproof cover to prevent the signal transmission line 140 from short-circuiting when it encounters water.

[0058] For example, Figure 2 and Figure 3 As shown in FIG. 1 , at least one through hole 114 is provided on the housing 110, and the through hole 114 is used to set a camera assembly. The camera assembly can collect image information of the environment, thereby improving the monitoring effect of the radar device 100.
