[0030] In some embodiments, the air-permeable film 103 is configured as a waterproof air-permeable film, thereby preventing rainwater from entering the installation cavity 101 to damage the electrical elements of the radar device 500. Specifically, the casing 10 is provided with at least one through hole 104 communicating the installation cavity 101 and the outside air. The air-permeable film 103 covers all the through holes 104.

The number of air-permeable films 103 and the number of through holes 104 can be set according to the specifications of the radar device 500 and other factors, and the present embodiment of the utility model is not specifically limited.

[0031] In some embodiments, the radar device 500 further comprises a gasket 13. The gasket 13 covers the heat dissipation hole 102, thereby avoiding the outside dust or other impurities from entering the installation cavity 101 to affect the detection accuracy of the transceiver component 20. The gasket 13 can be configured as an air-permeable film 103. In some embodiments, the gasket 13 can be configured as a waterproof air-permeable film, thereby preventing rainwater from entering the installation cavity 101 to damage the electrical elements of the radar device 500.

[0032] Exemplarily, in the present embodiment, the transceiver component 20 comprises a mounting bracket 21, a transmitter 22 and a receiver 23. The transmitter 22 and the receiver 23 are mounted on the mounting bracket 21. The airflow generating component 30 is rotatably arranged relative to the casing 10 and fixedly connected with the mounting bracket 21. Thus, the transceiver component 20 can rotate with the airflow generating component 30 through the mounting bracket 21, thereby improving the heat exchange rate of the transceiver component 20 and the airflow generated by the airflow generating component 30, promoting the rapid diffusion of the heat generated by the transceiver component 20 in operation, and thereby improving the heat dissipation effect of the radar device 500 and prolonging the service life of the radar device 500.

[0033] Of course, in some embodiments, the mounting rack 21 and the airflow generating component 30 are arranged independently. In other words, the transceiving component 20 is fixedly arranged relative to the casing 10, and the airflow generating component 30 is rotatably arranged relative to the casing 10. The airflow generating component 30 comprises a base plate 31 and a plurality of blades 32 arranged on the base plate 31. In some embodiments, the base plate 31 is fixedly connected to the casing 10, the plurality of blades 32 are rotatably arranged on the base plate 31, and the mounting rack 21 is fixedly connected to the base plate 31 and / or the casing 10. In other embodiments, the plurality of blades 32 are fixedly arranged on the base plate 31, the mounting rack 21 is fixedly arranged on the base plate 31, and the base plate 31 is rotatable relative to the casing 10.

[0034] In some embodiments, the mounting rack 21 comprises a mounting portion 211 and a supporting portion 212. The mounting portion 211 is arranged at an acute angle relative to the extending direction of the supporting portion 212, the transceiving component 20 is arranged on the mounting portion 211, and the two ends of the supporting portion 212 are respectively connected to the mounting portion 211 and the airflow generating component 30, and the supporting portion 212 is used for supporting the mounting portion 211. In this way, the supporting portion 212 is connected to the mounting portion 211 and the airflow generating component 30 to form a triangular structure, thereby improving the stability of the center of gravity of the transceiving component 20, and improving the reliability and accuracy of the detection work of the transmitter 22 and the receiver 23. Specifically, the mounting portion 211 is arranged at an acute angle relative to the base plate 31 of the airflow generating component 30, thereby improving the emission range or the receiving range of the emitted light and the reflected light of the transceiving component 20, and improving the space utilization of the transmitter 22 and the receiver 23 in the mounting cavity 101, and the structure is compact and simple. The supporting portion 212 is arranged in two, and the two supporting portions 212 are connected to the two sides of the mounting portion 211, thereby improving the stability and reliability of the supporting portion 212 supporting the mounting portion 211, and providing installation space for other structures between the two supporting portions 212. Of course, in some embodiments, the supporting portion 212 can be arranged in one, and the supporting portion 212 can be connected to the middle or other positions of the mounting portion 211; or, the supporting portion 212 is arranged in more than two, and the embodiments of the present application are not limited in this regard.

[0035] The supporting portion 212, the mounting portion 211 and the base plate 31 can be connected to each other to form an integral structure, thereby improving the reliability and stability of the connection of the supporting portion 212, the mounting portion 211 and the base plate 31. In other words, the supporting portion 212, the mounting portion 211 and the base plate 31 can be integrally formed. Of course, in some embodiments, at least two of the supporting portion 212, the mounting portion 211 and the base plate 31 are arranged independently, thereby reducing the processing difficulty of the supporting portion 212, the mounting portion 211 and the base plate 31, and facilitating maintenance. Of course, in other embodiments, the supporting portion 212 can be omitted, that is, the mounting rack 21 only comprises the mounting portion 211.

[0036] In some embodiments, the radar device 500 further comprises a partition 24 disposed in the mounting cavity 101. The partition 24 is located on the side of the mounting frame 21 facing the signal transmission / reception of the transceiver component 20, and is located between the transmitter 22 and the receiver 23. The partition 24 is used to avoid interference of the signals of the transmitter 22 and the receiver 23, so as to improve the working stability of the transmitter 22 and the receiver 23, and improve the positioning accuracy of the radar device 500.

[0037] In some embodiments, the transceiver component 20 further comprises a first circuit board 25 and a second circuit board 26. The first circuit board 25 is connected with the transmitter 22 and is disposed on different sides of the mounting frame 21. The receiver 23 is connected with the second circuit board 26 and is disposed on different sides of the mounting frame 21. The receiver 23 is disposed on the same side of the mounting frame 21 as the transmitter 22. In this way, based on the first circuit board 25 and the second circuit board 26 being respectively disposed apart from the transmitter 22 and the receiver 23 through the mounting frame 21, on the one hand, the first circuit board 25 and the second circuit board 26 are prevented from respectively shielding the transmitted light and the reflected light, so as to improve the transmission efficiency of the transmitted light by the transmitter 22 and the reception efficiency of the reflected light by the receiver 23; on the other hand, the transmitted light and the reflected light are reduced to cause damage to the photosensitive elements or other functional elements on the first circuit board 25 and the second circuit board 26; and on the other hand, the stability of the center of gravity of the transceiver component 20 is improved, and the risk of shaking of the transmitter 22 and the receiver 23 of the transceiver component 20 is reduced. Specifically, the first circuit board 25 can be used to control the parameters of the transmitted light of the transmitter 22, and the second circuit board 26 can be used to process the reflected light received by the receiver 23. Of course, in some embodiments, the transceiver component 20 can omit at least one of the first circuit board 25 and the second circuit board 26, and the embodiments of the present application are not limited in this regard.

[0038] In some embodiments, the mounting frame 21 is provided with two mounting holes 210, and the transmitter 22 and the receiver 23 are respectively fixed in the two mounting holes 210. The mounting frame 21 can be provided with a fixing column 213. The fixing column 213 is located on the side of the mounting portion 211 away from the transmitter 22 and the receiver 23, i.e., on the side of the mounting portion 211 close to the first circuit board 25 and the second circuit board 26. The fixing column 213 is provided in plurality, and the plurality of fixing columns 213 are located on the circumferential side of the two mounting holes 210. The first circuit board 25 and the second circuit board 26 are respectively fixed to one end of the fixing column 213 away from the mounting portion 211.

[0039] In some embodiments, the transceiving component 20 further comprises a first heat dissipation structure 27. The first heat dissipation structure 27 is arranged on the side of the first circuit board 25 facing away from the mounting frame 21. The receiver 23 further comprises a second heat dissipation structure 28. The second heat dissipation structure 28 is arranged on the side of the second circuit board 26 facing away from the mounting frame 21. In this way, on the one hand, the arrangement of the first heat dissipation structure 27 and the second heat dissipation structure 28 can promptly dissipate the heat generated by the first circuit board 25 and the second circuit board 26, reducing the influence of the high-temperature environment on the detection effect of the transceiving component 20; on the other hand, the arrangement of the first heat dissipation structure 27 and the second heat dissipation structure 28 can also increase the heat exchange area with the airflow generated by the airflow generating component 30, promoting the rapid diffusion of the heat generated by the transceiving component 20 during operation, thereby improving the heat dissipation effect of the radar device 500 and prolonging the service life of the radar device 500.

[0040] Specifically, the first heat dissipation structure 27 and the second heat dissipation structure 28 each comprise a plurality of fin bodies 29, which are arranged at intervals in the arrangement direction of the transceiving component 20 and the airflow generating component 30, and adjacent two fin bodies 29 form a heat dissipation channel 2901. The extension direction of the heat dissipation channel 2901 forms an included angle a with the plane perpendicular to the rotation axis of the airflow generating component 30, and the included angle a is less than or equal to 45°. Understandably, when the included angle a is too large, the airflow generated by the airflow generating component 30 is prone to separation on the surface of the fin body 29 and forms a vortex, thereby causing high-frequency noise to be generated; when the included angle a is too small, the heat contact area between the airflow generated by the airflow generating component 30 and the fin body 29 is reduced, thereby reducing the heat exchange efficiency. Thus, when the radar device 500 is working, the fin bodies 29 rotate with the transceiving component 20 following the rotation of the airflow generating component 30, and the internal gas of the mounting cavity 101 flows in the heat dissipation channel 2901 formed by adjacent two fin bodies 29, on the one hand, the heat exchange area between the gas and the fin body 29 is increased, thereby improving the heat dissipation efficiency and heat dissipation effect; on the other hand, the present embodiment sets an appropriate included angle a, so that the airflow generated by the airflow generating component 30 can more smoothly adhere to the surface of the fin body 29, reducing turbulence and vortex, thereby the transceiving component 20 can reduce the noise generated by the fin body 29 when following the rotation of the airflow generating component 30, and the heat contact area between the fin body 29 and the airflow generated by the airflow generating component 30 is large, thereby improving the heat dissipation effect of the radar device 500. The included angle a is, for example, but not limited to, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40° or 45°, etc. Exemplarily, in the present embodiment, the included angle a is 15°.

[0041] The air flow generating component 30 is configured as a flat plate structure, so that the structure of the air flow generating component 30 is simple, space is saved, and vibration noise is reduced. In this embodiment, for example, a plurality of blades 32 are arranged on the base plate 31 and extend in the radial direction of the base plate 31. The driving component 50 is configured to drive the plurality of blades 32 to rotate. The base plate 31 is fixedly connected to the mounting frame 21 and rotationally connected or fixedly connected to the plurality of blades 32. Thus, when the blades 32 of the air flow generating component 30 rotate, the blades 32 apply pressure to the air in the mounting cavity 101, causing the air to flow in and out of the casing 10 and forming a relatively stable circulating air flow, thereby improving the heat dissipation effect and efficiency of the radar device 500. For example, the driving component 50 can be configured as a direct current motor or an alternating current motor. The direct current motor can be a brush direct current motor or a brushless direct current motor. When the driving component 50 is configured as a brush direct current motor, the driving component 50 changes the direction of the current through the brush and the commutator to drive the air flow generating component to rotate. When the driving component 50 is configured as a brushless direct current motor, the driving component 50 drives the air flow generating component to rotate through electronic commutation. When the driving component 50 is configured as an alternating current motor, the driving component 50 drives the air flow generating component to rotate by generating a rotating magnetic field through alternating current.

[0042] In some embodiments, the transceiving component 20 is connected to the air flow generating component 30 to form a rotational connection structure 40. The center of gravity of the rotational connection structure 40 coincides with or is spaced apart from the central axis of the output shaft of the driving component 50 by a predetermined distance. Thus, by setting the perpendicular distance between the center of gravity of the rotational connection structure 40 and the central axis of the output shaft of the driving component 50, the present application avoids the problem of the transceiving component 20 in the radar device 500 shaking when following the air flow generating component 30 rotating relative to the casing 10, prolongs the service life of the transceiving component 20, and improves the reliability and accuracy of the detection work of the transceiving component 20.

[0043] It should be noted that the predetermined distance refers to the maximum perpendicular distance between the center of gravity of the rotational connection structure 40 and the central axis of the output shaft of the driving component 50 when the shaking parameter of the transceiving component 20 is less than the predetermined shaking parameter during the process of the transceiving component 20 following the air flow generating component 30 rotating relative to the casing 10. It can be understood that the predetermined distance can be configured according to the weight, shape, etc. of the rotational connection structure 40 or the transceiving component 20, or by adjusting the first heat dissipation structure 27 and the second heat dissipation structure 28 to reduce the center of gravity offset of the rotational connection structure 40, thereby reducing the shaking of the transmitter 22 and the receiver 23 in the transceiving component 20 and improving the service life of the radar device 500.

[0044] Exemplarily, in the embodiment, the casing 10 comprises a mounting base 11 and a protective cover 12. The protective cover 12 is detachably connected with the mounting base 11 to form a mounting cavity 101. The protective cover 12 is located above the mounting base 11. The bottom of the mounting base 11 is provided with a heat dissipation hole 102, and the top of the protective cover 12 is provided with a breathable film 103. In this way, on the one hand, based on the detachable connection between the protective cover 12 and the mounting base 11, the disassembly, replacement and maintenance of the internal elements of the radar device 500 are facilitated, and the use flexibility is improved. On the other hand, the heat dissipation hole 102 is arranged at the bottom of the mounting base 11, and the breathable film 103 is arranged at the top of the protective cover 12, so as to avoid the entry of external impurities into the mounting cavity 101 and affect the detection accuracy of the transceiver component 20, prevent rainwater from entering the mounting cavity 101 and damaging the electrical elements of the radar device 500, and the cooling airflow generated by the airflow generating component 30 can first pass through the transceiver component 20 to quickly take away the heat generated by the transceiver component 20, thereby improving the detection accuracy of the transceiver component 20.
