[0034] As attached Figure 1 To Attachment Figure 5 As shown, a radar device comprises: a support base 40 and a radar 60.

[0035] The support seat 40 has a receiving cavity 20, the inner wall surface of the receiving cavity 20 is a spherical surface, including a spherical concave surface 21, and has a spherical center 50. The support seat 40 also has a first opening 42 and a second opening 43. The first opening 42 and the second opening 43 are arranged on opposite sides of the support seat 40 and are respectively connected to the receiving cavity 20, and the apertures of the first opening 42 and the second opening 43 are both smaller than the cavity diameter of the receiving cavity 20.

[0036] The shape and size of the radar 60 match the accommodating cavity 20, and the radar 60 is swingably embedded in the accommodating cavity 20 around the spherical center 50. A portion of the radar 60 is located outside the accommodating cavity 20 through the first opening 42 and is used to emit electromagnetic waves. Another portion of the radar 60 is located outside the accommodating cavity 20 through the second opening 43 and is used to exchange heat with the outside.

[0037] In the radar device of this solution, a rotating cavity with a concave spherical surface is formed by opening a receiving cavity 20 on the support base 40, and the radar 60 is movably embedded in the receiving cavity 20, so that the radar 60 and the support base 40 can swing around the spherical center 50 in the receiving cavity 20, that is, the pitch angle and the left and right yaw angle of the radar 60 can be adjusted. This structure can make the radar have a wider adjustable angle range.

[0038] As attached Figure 3 and attached Figure 4 As shown, in some embodiments, the support base 40 includes a fixing base 1 and a card base 2. The card base 2 is detachably connected to the fixing base 1, and the card base 2 and the fixing base 1 are connected to form the accommodating cavity 20, the first opening 42 and the second opening 43. A pair of connecting surfaces of the card base 2 and the fixing base 1 are planes and pass through the spherical center 50, or are respectively located on opposite sides of the spherical center 50, and it is necessary to ensure that the apertures of the openings of the fixing base and the card base are both less than or equal to the spherical diameter to facilitate the installation of the radar.

[0039] The fixing seat 1 and the card seat 2 are both provided with hemispherical grooves 3, and the fixing seat 1 and the card seat 2 are spliced ​​so that the two groups of hemispherical grooves 3 are combined to form the accommodating cavity 20, the first opening 42 and the second opening 43. The inner spheres of the two hemispherical grooves 3 are combined to form a spherical concave surface 21. The fixing seat 1 and the card seat 2 are detachable, which can facilitate the installation and disassembly operations of the spherical outer shell 4 and the support seat 40, and is more convenient for the subsequent disassembly and maintenance of the radar.

[0040] It is understandable that the spherical concave surface 21 can be a complete and continuous annular surface, or a disconnected annular surface, which is determined according to the spacing between the fixing seat 1 and the card seat 2. Preferably, a complete and continuous annular surface is used in this embodiment, that is, the facing surfaces of the fixing seat 1 and the card seat 2 are in a mutually fitting form. The spherical concave surface 21 in the form of a complete and continuous annular surface can make the relative rotation of the spherical shell 4 and the support seat 40 smoother.

[0041] A connecting hole 22 is provided through the base 2, and an axial extension line of the connecting hole 22 is located outside the accommodating cavity 20. More specifically, the connecting hole 22 is perpendicular to the joint surface of the base 2 and the fixed base 1. When the fixed base 1 and the base 2 are joined, an internal threaded mounting hole is provided on a side wall of the fixed base 1 facing the joint surface, corresponding to the connecting hole. A connecting screw 23 is movably provided in the connecting hole 22, and the base 2 is locked to the fixed base 1 by the connecting screw 23. The structure is simple and easy to disassemble and assemble.

[0042] In some embodiments, the holder 2 may also be coupled with the fixing seat 1 by means of buckles, clamps, magnets, welding, etc., so that both the fixing seat 1 and the holder 2 remain fixed.

[0043] The radar 60 includes a spherical outer shell 4 and a radar body 7 arranged in the inner cavity of the spherical outer shell 4. The outer wall of the spherical outer shell 4 includes an outer spherical surface 41 matching the spherical concave surface 21. The spherical outer shell 4 is axially fixed and circumferentially rotatable on the support seat 40 corresponding to the accommodating cavity 20. The circumferential rotation includes: the spherical outer shell 4 can rotate around the axis of the hole of the accommodating cavity 20, and the spherical outer shell 4 can be rotated inward or outward relative to the hole edge of the accommodating cavity 20 with the center of the spherical concave surface 21 as the rotation center.

[0044] The spherical shell 4 is a spherical structure with an inner cavity structure, and an opening 5 for the radar body 7 to transmit and receive electromagnetic waves is provided on the spherical shell 4 corresponding to the first opening 42, and a front cover 6 is detachably provided corresponding to the opening 5, and the front cover 6 is fixed to the spherical shell 4 by a connection structure such as screws or buckles, and blocks the opening 5. The front cover 6 is a transparent plastic cover body, which reduces the attenuation of radar waves and can also protect the installation cavity inside the spherical shell 4.

[0045] A heat dissipation module 10 is provided on the spherical housing 4 corresponding to the second opening 43. The heat dissipation module 10 is arranged in close contact with the spherical housing 4 to discharge the heat generated by the spherical housing 4 and the radar body 7 inside the spherical housing 4 to the outside, thereby reducing the high temperature effect inside the spherical housing 4 and ensuring the normal operation of the radar body 7.

[0046] In one embodiment, the outer contour of the spherical shell 4 is a truncated cone structure, one truncated cone surface is the front cover 6, and the other truncated cone surface is used to install the heat dissipation module 10. Installing the heat dissipation module 10 in this way is not only convenient for installation, but also can have a larger heat conduction surface with the spherical shell 4, thereby improving the heat dissipation efficiency.

[0047] It is understandable that the heat dissipation module 10 can be directly set on the frustum of the spherical shell 4 by means of fixing structures such as screws, or holes can be opened on the frustum so that the heat absorption end of the heat dissipation module can directly extend into the inner cavity of the spherical shell, thereby further improving the heat dissipation efficiency.

[0048] In this embodiment, the heat dissipation module is arranged on the outside of the truncated table surface. The heat dissipation module 10 includes a plurality of heat dissipation fins arranged at intervals. The heat dissipation fins may be made of plastic or aluminum sheets.

[0049] As attached Figure 3-5 As shown, the spherical surface of the accommodating cavity 20 is a spherical concave surface 21, and the radar 60 includes an outer spherical surface 41 adapted to the spherical surface. A damping member is provided on the spherical concave surface 21 of the accommodating cavity 20. The damping member is a flexible member, and the damping member is in elastic contact with the outer spherical surface 41. The damping member damps the rotation adjustment of the spherical shell 4 relative to the support seat 40. When the radar 60 is adjusted in angle, the damping member can increase the friction between the radar 60 and the spherical concave surface 21 to prevent the radar 60 from slipping in the accommodating cavity 20 when no external force is applied, so that the radar 60 can remain fixed at any position within the angle adjustment range, thereby improving the stability of the angle adjustment.

[0050] The damping member is a rubber ring 9 , and at least one rubber ring 9 is coaxially arranged on the inner side surface of the accommodating cavity 20 . The damping force can be increased by one or more rubber rings 9 .

[0051] More specifically, at least one rubber ring 9 is respectively provided at the edge of the first opening 42 and the second opening 43 of the accommodating cavity 20. Through two groups of rubber rings 9 corresponding to the edges of the openings, the rubber rings 9 seal the gap between the spherical housing 4 and the edge of the accommodating cavity 20, and can prevent water and dust from the gap space, thereby ensuring that the spherical housing 4 and the accommodating cavity 20 always rotate smoothly relative to each other.

[0052] An arc-shaped groove 8 for embedding the rubber ring 9 is concavely formed on the inner peripheral wall of the accommodating cavity 20 so as to fix and install the rubber ring 9 in the axial direction.

[0053] It can be understood that the clamping mechanism in the present solution can be a manually adjustable clamping mechanism, or an electric or pneumatic clamping mechanism. The more preferred one is a manually adjustable clamping mechanism, which has lower cost and lower failure rate.

[0054] As attached Figure 1 To Attachment Figure 5 As shown, it also includes a clamping mechanism 30, which is arranged on the support seat 40. Specifically, the clamping mechanism 30 is arranged on the fixed seat 1, and the support seat 40 is detachably clamped or separated from the carrier by the clamping mechanism 30, so as to facilitate the installation and fixation of the overall mechanism, as well as disassembly and maintenance, and the use of the clamping mechanism 30 has a wider range of applications.

[0055] The clamping mechanism 30 includes a fixed clamping plate 11, a movable clamping plate 12 and a clamping adjustment component. The fixed clamping plate 11 is relatively fixedly arranged on the support seat 40. The fixed clamping plate 11 can be a part of the fixed seat 1 itself, or it can be an independent structure fixed on the fixed seat 1. The movable clamping plate 12 is movable and guided on the support seat 40, and the movable clamping plate 12 is adjusted relative to the fixed clamping plate 11 by the clamping adjustment component. The position of the movable clamping plate 12 is adjusted by the clamping adjustment component, so as to adjust the distance between the fixed clamping plate 11 and the movable clamping plate, so that it is suitable for different carriers. The carrier can be any object that can be used for clamping and fixing, such as a rod body, a plate body, etc. The fixed clamping plate 11 and the movable clamping plate 12 are clamped loosely or tightly on the carrier. The loose and tight clamping is performed by the relative displacement of a fixed component and a movable component, which can be more convenient during installation and disassembly, and has stronger versatility.

[0056] Among them, a guide rod 13 is arranged on the side wall of the movable clamping plate 12 facing the fixed clamping plate 11. In this embodiment, two groups of guide rods 13 are arranged at intervals. A guide hole 14 is opened on the fixed clamping plate 11 or the fixed seat 1 corresponding to the guide rod 13. The guide rod 13 is inserted into the guide hole 14 for movable guidance. When the movable clamping plate 12 is adjusted for far and near displacement relative to the fixed clamping plate 11, it can be guided by the guide rod 13 and the guide hole 14. The cross-sectional profile of the guide rod 13 and the guide hole 14 is the same, such as circular, semicircular, triangular, square, polygonal, etc.

[0057] The clamping adjustment assembly includes an adjusting screw 17 and a connecting sleeve 16. The connecting sleeve 16 is located between the two groups of guide rods 13. One end of the adjusting screw 17 includes a blocking portion 18. The blocking portion 18 is used to prevent the adjusting screw 17 from passing through the fixed clamp 11 completely. At the same time, the blocking portion 18 can also be used as a hand-tightening portion to screw the adjusting screw 17. The fixed clamp 11 is provided with a through hole 15 for the other end of the adjusting screw 17 to pass through. The movable clamp 12 is coaxially provided with a connecting sleeve 16 with the adjusting screw 17. The connecting sleeve 16 includes an internal thread section for connecting the adjusting screw 17. The adjusting screw 17 is adjusted relative to the connecting sleeve 16 to adjust the spacing of the movable clamp 12 relative to the fixed clamp 11.

[0058] During the clamping operation, the operation process is as follows: the adjusting screw 17 is driven to rotate by screwing the blocking portion 18, and the adjusting screw 17 will drive the connecting sleeve 16 to slide in the through hole 15 in the direction away from the fixed splint 11, so that the connecting sleeve 16 will drive the movable splint 12 fixedly connected thereto away from the fixed splint 11, and a distance will be generated between the movable splint 12 and the fixed splint 11. At this time, the fixed splint 11 is clamped on the cross bar, and then the blocking portion 18 is reversed, and the adjusting screw 17 will drive the connecting sleeve 16 to move in the opposite direction and reset, thereby driving the movable splint 12 close to the cross bar, and at this time the fixed splint 11 and the movable splint 12 clamp the cross bar from both sides.

[0059] The clamping surface of the fixed clamping plate 11 and / or the movable clamping plate 12 is a concave surface. When both the fixed clamping plate 11 and the movable clamping plate 12 are provided with concave surfaces, the two groups of concave surfaces are symmetrical about the clamping surface. The concave surface can be, for example, a V-shaped groove or an arc groove structure, and the extension direction of the concave surface can also be set according to actual needs.

[0060] The clamping surface of the fixed clamping plate 11 and / or the movable clamping plate 12 is provided with an anti-skid pad 19 , which is a rubber pad. The anti-skid pad 19 can increase the clamping friction and improve the clamping stability.

[0061] The introduction provided in the above steps is only used to help understand the method, structure and core idea of ​​the present application. For ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
