[0028] The technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application.

[0029] In this document, reference to“an embodiment” or“the embodiments” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are the various embodiments mutually exclusive or mutually inclusive of other embodiments. It is expressly understood that the embodiments described herein are merely examples from a multitude of possible embodiments, which represent the application.

[0030] It should be noted that the terms“first”,“second” and the like in the description and in the claims of the present application and above-described drawings are used only for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. The terms“and / or” in the present application refers to any combination of associated listed terms and all possible combinations, including one or more of the associated listed terms.

[0031] Please refer toFigure 1 , Figure 1 This is a schematic diagram of the radar device 500 provided in this embodiment of the present invention. The radar device 500 includes a housing 10, a transceiver component 20, an airflow generating component 30, and a drive component 50. The housing 10 is provided with a mounting cavity 101. A first heat dissipation fin 111 is provided on the inner sidewall of the housing. The transceiver component 20, the airflow generating component 30, and the drive component 50 are respectively disposed in the mounting cavity 101. The drive component 50 is used to drive the airflow generating component 30 to rotate. When the airflow generating component 30 rotates, it drives the gas to flow in the mounting cavity 101 and pass through the first heat dissipation fin 111. Thus, when the driving component 50 drives the airflow generating component 30 to rotate, the airflow generating component 30 drives the gas to flow within the mounting cavity 101, forming a circulating airflow. As the gas passes through the transceiver component 20, it carries away the heat from the transceiver component 20. Furthermore, when the gas passes through the first heat dissipation fins 111, the increased heat dissipation area of ​​the inner wall of the housing 10 improves the heat exchange efficiency between the housing 10 and the air in the mounting cavity 101, thereby enhancing the heat dissipation efficiency of the housing 10. This ensures that the heat generated by the transceiver component 20 during operation can be dissipated to the outside of the housing 10 in a timely manner, preventing overheating of the radar device 500 and improving its service life and operational reliability. In addition, the airflow generated by the airflow generating component 30 can also improve the heat distribution uniformity within the mounting cavity 101, preventing localized overheating and thus preventing overheating of the transceiver component 20.

[0032] It should be noted that, Figure 1 The purpose is merely to schematically describe the arrangement of the housing 10, transceiver 20, airflow generating component 30 and drive component 50, and is not to specifically limit the connection position, connection relationship and specific structure of each component. Figure 1 The diagram only illustrates the structure of the radar device 500 in this embodiment and does not constitute a specific limitation on the radar device 500. In other embodiments of this application, the radar device 500 may include components such as... Figure 1 The radar device 500 may include, but is not limited to, more or fewer components, combinations of certain components, or different components, such as a temperature sensor and a prompting structure. The temperature sensor is used to detect the temperature within the mounting cavity 101. The driving component 50 and the transceiver component 20 may not operate simultaneously. For example, when the temperature detected by the temperature sensor is higher than a preset temperature, the driving component 50 is controlled to drive the airflow generating component 30 to operate. Of course, in some embodiments, the driving component 50 and the transceiver component 20 may operate simultaneously. The radar device 500 can also adjust the operating parameters of the airflow generating component 30 according to the temperature detected by the temperature sensor. The prompting structure is used to characterize the operating status of the radar device 500.

[0033] In the embodiment, the first heat dissipation fins 111 are arranged in a plurality of numbers. The first heat dissipation fins 111 are arranged at intervals. The air flow channels 104 are formed between two adjacent first heat dissipation fins 111. The air flow channels 104 are in communication with the installation cavity 101. The air flow generated by the rotation of the air flow generating component 30 can flow into the air flow channels 104, so that the heat in the air is conducted to the casing 10 through the side walls of the first heat dissipation fins 111, and then the heat is dissipated to the outside of the installation cavity 101 through the casing 10, thereby reducing the internal temperature of the installation cavity 101.

[0034] In the embodiment, the first heat dissipation fins 111 can be arranged as protruding structures protruding on the inner side wall of the casing 10. The extension direction of the first heat dissipation fins 111 is arranged at an angle with the plane perpendicular to the rotation axis of the air flow generating component 30, and the extension direction of the air flow channel 104 is arranged at an angle with the plane perpendicular to the rotation axis of the air flow generating component 30, so as to reduce the blocking effect of the first heat dissipation fins 111 on the air flow generated by the air flow generating component 30, so that the air flow can flow along the extension direction of the air flow channel 104, and the air flow is prevented from accumulating at the local position of the first heat dissipation fins 111, so that each position of the first heat dissipation fins 111 can be in contact with the air flow, effective heat exchange is achieved, and the flow rate of the air flow in the air flow channel 104 is improved, thereby improving the heat dissipation capacity of the first heat dissipation fins 111.

[0035] In the embodiment, the first heat dissipation fins 111 can be arranged in a spiral shape and extend spirally along the rotation axis direction of the air flow generating component 30. The plurality of first heat dissipation fins 111 are arranged at intervals along the rotation direction of the air flow generating component 30.

[0036] In some embodiments, the plurality of first heat dissipation fins 111 can be arranged in sequence along the spiral direction, the plurality of first heat dissipation fins 111 can be arranged at intervals along the spiral direction, or the plurality of first heat dissipation fins 111 can be connected end to end along the spiral direction to form an integral whole, and the air flow channel 104 is formed at intervals between two first heat dissipation fins 111 adjacent along the rotation axis direction of the air flow generating component 30. In some embodiments, the first heat dissipation fins 111 can also extend along the direction parallel to the rotation axis of the air flow generating component 30.

[0037] In some embodiments, the inner side wall of the casing 10 is provided with a groove structure, and the air flow channel 104 is formed in the groove structure. In the embodiment, the casing 10 can form a protruding structure between two adjacent groove structures to space the two adjacent groove structures.

[0038] The air flow passage 104 has an opening 1041 on the side close to the air flow generating component 30. In a projection plane perpendicular to the rotation axis of the air flow generating component 30, the orthographic projection of the air flow generating component 30 at least partially coincides with the orthographic projection of the opening 1041, so as to facilitate the air flow generated by the air flow generating component 30 to flow into the air flow passage 104 through the opening 1041 and flow to various positions of the first heat dissipation fins 111, thereby improving the heat dissipation efficiency of the radar device 500.

[0039] Exemplarily, in the present embodiment, the housing 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. In this way, 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 can be facilitated, and the use flexibility is improved.

[0040] The first heat dissipation fins 111 are arranged on the inner side wall of the mounting base 11. The transceiver component 20 is arranged in the protective cover 12. In this way, the first heat dissipation fins 111 can avoid the transceiver component 20, so as to avoid the interference of the first heat dissipation fins 111 with the signal transmission and reception of the transceiver component 20. In some embodiments, the first heat dissipation fins 111 can be arranged on the inner side wall of the protective cover 12. The first heat dissipation fins 111 are arranged to avoid the sweep area of the transceiver component 20 on the protective cover 12, so as to avoid the interference of the first heat dissipation fins 111 with the signal transmission and reception of the transceiver component 20. In some embodiments, the first heat dissipation fins 111 can be arranged on the inner side wall of the protective cover 12 and the inner side wall of the mounting base 11.

[0041] Specifically, in the present embodiment, the inner side wall of the mounting base 11 is provided with a plurality of first heat dissipation fins 111. The plurality of first heat dissipation fins 111 are arranged on the inner side wall of the mounting base 11 in the rotation direction of the air flow generating component 30. The plurality of first heat dissipation fins 111 are arranged in a spiral shape. In this way, the heat exchange area between the mounting base 11 and the air flow generated by the air flow generating component 30 is increased, and the heat dissipation effect and efficiency of the radar device 500 are improved. Of course, in some embodiments, the first heat dissipation fins 111 can be arranged in multiple turns on the inner side wall of the mounting base 11 in the rotation direction of the air flow generating component 30.

[0042] In some embodiments, the mounting base 11 is configured as a heat dissipation structure. In this way, the mounting base 11 can directly export part of the heat to the outside air or the body 100 of the walking device 1000, thereby improving the heat dissipation effect of the radar device 500. The material of the heat dissipation structure includes, but is not limited to, at least one of metal, alloy, inorganic glass, plastic, etc. Of course, in some embodiments, both the mounting base 11 and the protective cover 12 can be configured as heat dissipation structures, and the embodiments of the present application are not limited specifically.

[0043] Specifically, the mounting base 11 is provided with a first cavity 1011. The protective cover 12 is provided with a second cavity 1012. The first cavity 1011 and the second cavity 1012 form a mounting cavity 101. The driving component 50 is arranged in the first cavity 1011. The transceiving component 20 is arranged in the second cavity 1012. The airflow generating component 30 is arranged between the first cavity 1011 and the second cavity 1012. In this way, on the one hand, the airflow generating component 30 is arranged between the driving component 50 and the transceiving component 20, which can avoid the driving component 50 and the transceiving component 20 from being concentrated in one of the cavities of the mounting cavity 101, thereby avoiding the heat from being concentrated in one of the cavities of the mounting cavity 101, so that the heat generated by the driving component 50 and the transceiving component 20 when working can be dissipated in time to the outside of the mounting cavity 101 through the mounting base 11 and the protective cover 12, thereby avoiding the problem of local overheating in the mounting cavity 101. On the other hand, multiple functional elements are arranged in a limited mounting space, and the structure layout is compact and reasonable.

[0044] In some embodiments, the outer side wall of the mounting base 11 is provided with at least one second heat dissipation fin 112. In this way, the heat exchange area between the mounting base 11 and the outside air is increased, and the heat dissipation effect and efficiency of the radar device 500 are improved. It should be noted that the inner side wall of the mounting base 11 refers to the inner side wall of the first cavity 1011, and the outer side wall of the mounting base 11 refers to the outer side wall of the first cavity 1011.

[0045] It should be noted that the second heat dissipation fin 112 can be configured as a protruding structure protruding outward or a groove structure recessed inward of the outer side wall of the mounting base 11. The structure and arrangement mode of the first heat dissipation fin 111 are applicable to the structure and arrangement mode of the second heat dissipation fin 112, which will not be described here. The structure and arrangement mode of the first heat dissipation fin 111 and the second heat dissipation fin 112 can be set according to the actual situation, and the embodiments of the present application are not limited specifically.

[0046] Exemplarily, in the embodiment, the transceiving component 20 comprises a mounting frame 21, a transmitter 22 and a receiver 23. The transmitter 22 and the receiver 23 are mounted on the mounting frame 21. The airflow generating component 30 is rotatably arranged relative to the casing 10 and fixedly connected with the mounting frame 21. In this way, the transceiving component 20 can rotate with the mounting frame 21 following the airflow generating component 30, so as to improve the heat exchange rate between the transceiving component 20 and the airflow generated by the airflow generating component 30, promote the rapid diffusion of the heat generated by the transceiving component 20 in operation, and further improve the heat dissipation effect of the radar device 500 and prolong the service life of the radar device 500.

[0047] Of course, in some embodiments, the mounting frame 21 and the airflow generating component 30 are independently arranged. The transceiving component 20 can be fixedly arranged relative to the casing 10, and the airflow generating component 30 is rotatably arranged relative to the casing 10. In some embodiments, the mounting frame 21 and the airflow generating component 30 are independently arranged, and the transceiving component 20 and the airflow generating component 30 are rotatably arranged relative to the casing 10.

[0049] In some embodiments, the mounting rack 21 comprises a mounting portion 211 and a supporting portion 212. The extending direction of the mounting portion 211 is arranged at an acute angle with the extending direction of the supporting portion 212. The mounting portion 211 is mounted with the transceiving component 20, and the two ends of the supporting portion 212 are respectively connected with the mounting portion 211 and the airflow generating component 30, and are used for supporting the mounting portion 211. In this way, the supporting portion 212 is connected with 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 angle with respect to the substrate 31 of the airflow generating component 30, thereby improving the emission range or reception range of the emitted light and 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 provided in two, and the two supporting portions 212 are connected to the two side portions of the mounting portion 211, thereby improving the stability and reliability of the supporting portion 212 supporting the mounting portion 211, and providing mounting space for other structures between the two supporting portions 212. Of course, in some embodiments, the supporting portion 212 can be provided in one, and the supporting portion 212 can be connected to the middle portion or other positions of the mounting portion 211; or the supporting portion 212 is provided in more than two, and the embodiments of the present application are not limited specifically.

[0050] The supporting portion 212, the mounting portion 211 and the substrate 31 can be connected with 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 substrate 31. In other words, the supporting portion 212, the mounting portion 211 and the substrate 31 can be integrally formed. Of course, in some embodiments, at least two of the supporting portion 212, the mounting portion 211 and the substrate 31 are independently arranged with each other, thereby reducing the processing difficulty of the supporting portion 212, the mounting portion 211 and the substrate 31, and facilitating maintenance. Of course, in some other embodiments, the supporting portion 212 can be omitted, that is, the mounting rack 21 only comprises the mounting portion 211.

[0051] In some embodiments, the radar device 500 further comprises a partition 24 arranged in the mounting cavity 101. The partition 24 is located on the side of the mounting rack 21 facing the signal transmission / reception of the transceiving 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.

[0052] Exemplarily, in the embodiment, the overall structure of the protective cover 12 is configured as a light-transmissive structure. In this way, the emission efficiency of the emitter 22 for emitting light and the reception efficiency of the receiver 23 for receiving reflected light are improved. Of course, in some embodiments, part of the structure of the protective cover 12 is configured as a light-transmissive structure, for example, the area of the protective cover 12 corresponding to the emitter 22 and the receiver 23 is configured as a light-transmissive structure; or the protective cover 12 is provided with a light-transmissive hole corresponding to the emitter 22 and the receiver 23.

[0053] In some embodiments, the transceiving component 20 further comprises a first circuit board 25 and a second circuit board 26.

The receiver 23 is connected with the second circuit board 26 and is arranged on different sides of the mounting bracket 21, and the receiver 23 is arranged on the same side of the mounting bracket 21 as the emitter 22. In this way, based on the first circuit board 25 and the second circuit board 26 being arranged separately from the emitter 22 and the receiver 23 by the mounting bracket 21, on the one hand, the first circuit board 25 and the second circuit board 26 are prevented from respectively shielding the emitted light and the reflected light, thereby improving the emission efficiency of the emitter 22 for emitting light and the reception efficiency of the receiver 23 for receiving reflected light; on the other hand, the emitted light and the reflected light are reduced in causing damage to 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 transceiving component 20 is improved, and the risk of the emitter 22 and the receiver 23 of the transceiving component 20 shaking is reduced. Specifically, the first circuit board 25 can be used to control the parameters of the emitted light of the emitter 22, and the second circuit board 26 can be used to process the reflected light received by the receiver 23.

The receiver 23 further comprises a second heat dissipation structure 28. The second heat dissipation structure 28 is disposed on a side of the second circuit board 26 facing away from the mounting frame 21. In this way, on the one hand, the first heat dissipation structure 27 and the second heat dissipation structure 28 can dissipate the heat generated by the first circuit board 25 and the second circuit board 26 in time, reducing the influence of the high-temperature environment on the detection effect of the transceiving component 20; on the other hand, 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.

[0056] Specifically, the first heat dissipation structure 27 and the second heat dissipation structure 28 each comprise a plurality of fin bodies 29, and the plurality of fin bodies 29 are disposed in a direction in which the transceiving component 20 and the airflow generating component 30 are arranged, and adjacent two fin bodies 29 form a heat dissipation channel 2901. The fin bodies 29 on the first heat dissipation structure 27 extend towards the first circuit board 25 away from the mounting frame 21. The fin bodies 29 on the second heat dissipation structure 28 extend towards the second circuit board 26 away from the mounting frame 21.

[0057] The extension direction of the heat dissipation channel 2901 and the plane perpendicular to the rotation axis of the airflow generating component 30 form an included angle a, 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 easy to separate on the surface of the fin body 29 and form 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 airflow generating component 30, and the gas in 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 the heat dissipation effect; on the other hand, the present application embodiment sets the included angle a to be appropriate, 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 airflow generating component 30 to rotate, 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°.

[0058] 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, the air flow generating component 30 includes a base plate 31 and a plurality of blades 32. The 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 used to drive the blades 32 to rotate.

[0059] In this embodiment, the base plate 31 is connected with the driving component 50 and is fixedly connected with the mounting frame 21. 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, so that the air flows in the casing 10 and forms 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 through the rotating magnetic field generated by the alternating current.

[0060] In some embodiments, the base plate 31 is provided with a gas guide hole 301. The gas guide hole 301 communicates the first cavity 1011 and the second cavity 1012. When the air flow generating component 30 rotates, the blades 32 push the air flow to form a pressure difference between the first cavity 1011 and the second cavity 1012, which hinders the flow of gas. The gas guide hole 301 can reduce the pressure difference between the first cavity 1011 and the second cavity 1012, so that the gas can flow smoothly between the first cavity 1011 and the second cavity 1012, forming a circulating air flow, thereby facilitating heat dissipation of the transceiver component 20.

[0061] The plurality of blades 32 are arranged on the circumferential wall of the substrate 31 and / or the hole wall of the air guiding hole 301. In some embodiments, the substrate 31 has a circular ring structure, and the outer wall of the substrate 31 is arranged opposite to the hole wall of the air guiding hole 301. In some embodiments, the plurality of blades 32 are arranged on the circumferential wall of the substrate 31 to increase the linear speed of the substrate 31 when the substrate 31 drives the blades 32 to rotate, thereby increasing the pushing force of the blades 32 on the air, the flow rate and the flow strength of the generated air flow, and the heat dissipation effect of the radar device 500. In some embodiments, the plurality of blades 32 are arranged on the hole wall of the air guiding hole 301 to reduce the radius of the air flow generating component 30 and the structural size of the radar device 500, which is conducive to the miniaturization design of the radar device 500. In some embodiments, the plurality of blades 32 are arranged on the circumferential wall of the substrate 31 and the hole wall of the air guiding hole 301 respectively. When the substrate 31 rotates, the flow direction of the air pushed by the blades 32 arranged on the circumferential wall of the substrate 31 is opposite to the flow direction of the air pushed by the blades 32 arranged on the hole wall of the air guiding hole 301, thereby increasing the pushing ability of the air flow generating component 30 on the air, the strength and the flow rate of the generated air flow, and the heat dissipation effect of the radar device 500.

[0062] In some embodiments, the transceiver component 20 and the air flow generating component 30 are connected to form a rotating connection structure 40. The center of gravity of the rotating connection structure 40 coincides with or is spaced apart from the central axis of the output shaft of the driving component 50 by a preset distance. Thus, the vertical distance between the center of gravity of the rotating connection structure 40 and the central axis of the output shaft of the driving component 50 is set, thereby avoiding the problem that the transceiver component 20 in the radar device 500 easily shakes when following the air flow generating component 30 to rotate relative to the shell 10, prolonging the service life of the transceiver component 20 and improving the reliability and accuracy of the detection work of the transceiver component 20.

[0063] It should be noted that the preset distance refers to the maximum vertical distance between the center of gravity of the rotating connection structure 40 and the central axis of the output shaft of the driving component 50 when the shaking parameter of the transceiver component 20 is less than the preset shaking parameter during the process that the transceiver component 20 follows the air flow generating component 30 to rotate relative to the shell 10. It can be understood that the preset distance can be configured according to the weight, shape, etc. of the rotating connection structure 40 or the transceiver component 20; or by arranging the first heat dissipation structure 27 and the second heat dissipation structure 28 to reduce the center of gravity offset of the rotating connection structure 40, thereby reducing the shaking of the transmitter 22 and the receiver 23 in the transceiver component 20 and improving the service life of the radar device 500.

The communication connection between the first communication module 72 and the second communication module 74 can be realized through optical signals or electromagnetic wave signals. In this way, on the one hand, the transceiver signal of the transceiver component 20 is transmitted in a wireless manner, thereby simplifying the connection circuit, and the structure is simple and compact, and the signal transmission effect and transmission efficiency are improved. In some embodiments, the communication connection between the first communication module 72 and the second communication module 74 can also be realized through a wired manner.
