Description

Technical Field

[0001] The present invention relates to the technical field of detection cameras, and in particular, to a camera lens and a detection camera. Background Art

[0002] In the current urban environment, with the sharp increase in the number of vehicles, the parking space detection technology in parking lots has become a key factor in improving parking efficiency and optimizing the user experience. Most of the existing parking space detection cameras adopt a hemispherical design. The detection lenses of these cameras are fixed inside the main housing assembly. When the lens angle needs to be adjusted, the entire detection lens must be disassembled, which is not only cumbersome but also time-consuming, greatly increasing the installation and maintenance costs.

[0003] In view of the above problems, adjustment mechanisms are provided in the prior art to achieve the adjustment of the orientation of the lens end. However, these adjustment mechanisms are often hidden inside the camera lens or the main housing assembly, resulting in the need for debugging in the open cover state, with complex operation and long time consumption. Moreover, since the lens is generally retracted inside the housing, it not only limits the field of view angle of the lens, reducing the number of parking spaces that can be monitored, but also makes it difficult to adjust the lens due to the narrow operating space. Summary of the Invention

[0004] The present invention provides a camera lens and a detection camera to solve the problem that it is inconvenient to adjust the lens angle of the camera lens of the detection camera in the prior art.

[0005] To achieve the above object, according to one aspect of the present invention, a camera lens is provided. The camera lens includes a cover plate assembly, a housing assembly, and a lens assembly fixedly arranged inside the housing assembly. The cover plate assembly includes a front cover plate and a rear cover plate that are buckled with each other. The front cover plate and the rear cover plate are buckled to form a spherical cavity. At least part of the housing assembly is arranged inside the spherical cavity and is in limit fit with the inner wall of the spherical cavity. The fastening degree between the front cover plate and the rear cover plate is adjustable to clamp or loosen the housing assembly. The lens assembly has a lens end, and the lens end protrudes from the housing assembly and the front cover plate. When the front cover plate and the rear cover plate loosen the housing assembly, the housing assembly can rotate to adjust the orientation of the lens end.

[0006] Furthermore, a first limiting structure is arranged between the inner side of the spherical cavity and the outer periphery of the housing assembly, and the first limiting structure is used to limit the rotation path of the housing assembly inside the spherical cavity.

[0007] Further, the first limiting structure includes a limiting groove provided on the outer periphery of the housing assembly and a limiting protrusion provided on the inner side of the front cover plate. The limiting protrusion extends into the limiting groove and is in limiting cooperation with a part of the inner wall of the limiting groove. At least part of the housing assembly is a spherical housing whose shape is adapted to the spherical cavity. The extending direction of the limiting protrusion coincides with a central axis of the housing assembly. When the front cover plate and the rear cover plate loosen the housing assembly, the position of the limiting protrusion in the limiting groove is adjustable and the limiting protrusion can rotate in the limiting groove to rotate the housing assembly in different directions and adjust the orientation of the lens end.

[0008] Further, the camera lens has a first direction, a second direction, and a third direction that are perpendicular to each other in pairs. The fastening direction of the front cover plate and the rear cover plate is the first direction. The radial cross-section of the housing assembly where the second direction and the third direction are located is the first cross-section. The limiting groove extends along the first direction and passes through the first cross-section. The radial cross-section of the spherical cavity where the second direction and the third direction are located is the second cross-section. The limiting protrusion extends along the second direction and its axis is located on the second cross-section. When the front cover plate and the rear cover plate clamp the housing assembly, the first cross-section and the second cross-section coincide. When the front cover plate and the rear cover plate loosen the housing assembly, the first cross-section and the second cross-section coincide or are spaced apart. The limiting protrusion is rotatably arranged in the limiting groove to rotate and adjust the orientation of the lens end around the second direction, and the limiting protrusion is movably arranged along the extending direction of the limiting groove to adjust the orientation of the lens end around the third direction.

[0009] Further, there are two sets of the first limiting structures, and the two sets of first limiting structures are symmetrically distributed at the center between the outer periphery of the housing assembly and the inner side of the spherical cavity.

[0010] Further, the front cover plate is rotatably arranged relative to the rear cover plate. An adjusting structure for adjusting the fastening degree between the two is provided between the front cover plate and the rear cover plate. When the front cover plate rotates counterclockwise relative to the rear cover plate, the front cover plate and the rear cover plate approach each other and clamp the housing assembly under the action of the adjusting structure. When the front cover plate rotates clockwise relative to the rear cover plate, the front cover plate and the rear cover plate move away from each other and loosen the housing assembly under the action of the adjusting structure.

[0011] Further, the adjusting structure includes a second limiting structure and an abutting structure. The second limiting structure is used to limit the relative position and relative rotation path of the front cover plate and the rear cover plate; the abutting structure has an abutting end and an abutting surface located on the side of the rear cover plate facing away from the front cover plate. The abutting surface and the abutting end are fixed relative to the rear cover plate and the front cover plate respectively. The abutting surface extends along the circumferential direction of the cover plate assembly. The distance between the abutting surface and the radial plane of the cover plate assembly gradually increases in the counterclockwise rotation direction of the front cover plate relative to the rear cover plate. The abutting end abuts against the abutting surface and the abutting position of the abutting end on the abutting surface is adjustable in the extending direction of the abutting surface.

[0012] Further, the second limiting structure includes a limiting waist-shaped hole and a transfer shaft. The limiting waist-shaped hole is provided on the rear cover plate and extends along the circumferential direction of the rear cover plate. The transfer shaft is correspondingly arranged on the side of the front cover plate facing the rear cover plate corresponding to the limiting waist-shaped hole. The transfer shaft passes through the limiting waist-shaped hole and its position within the limiting waist-shaped hole is adjustable; the abutting structure includes an abutting protrusion and an abutting block. The abutting protrusion is located on the side of the rear cover plate facing away from the front cover plate and on the inner side in the direction of the axis of the rear cover plate near the limiting waist-shaped hole. An abutting surface is formed on the side of the abutting protrusion facing away from the rear cover plate. The abutting block is arranged at one end of the transfer shaft facing away from the front cover plate. The abutting block extends radially in the direction of the axis of the front cover plate. The plane on the side of the abutting block facing the front cover plate forms an abutting end. When the abutting end abuts against the abutting surface, the abutting protrusion is located between the rear cover plate and the abutting block.

[0013] Further, a first toothed structure is arranged along the extending direction of the abutting surface, and a second toothed structure adapted to mesh with the first toothed structure is provided on the abutting end. The first toothed structure or the second toothed structure is an elastic structure.

[0014] Further, there are multiple sets of adjusting structures, and the multiple sets of adjusting structures are distributed at intervals along the circumferential direction of the cover plate assembly between the front cover plate and the rear cover plate.

[0015] Further, the camera lens further includes a damping structure. The damping structure includes a front damping silica gel part and a rear damping silica gel part. The front damping silica gel part is arranged inside the front cover plate, and the rear damping silica gel part is arranged inside the rear cover plate. The cover plate assembly clamps or relaxes the housing assembly through the damping structure.

[0016] Further, a wrench structure is arranged on the surface of the front cover plate facing away from the rear cover plate.

[0017] According to another aspect of the present invention, a detection camera is provided. The detection camera includes an upper cover assembly, a control board assembly, a main housing assembly, a supplementary light component, a lamp shade assembly, and the above-mentioned camera lens. The upper cover assembly and the main housing assembly form a receiving cavity for placing the control board assembly and the camera lens. The main housing assembly has a plurality of mounting holes in the circumferential direction. A camera lens is fixedly installed at any one of the mounting holes. The supplementary light component is arranged inside the lamp shade assembly, and the lamp shade assembly is arranged at the bottom of the main housing assembly.

[0018] Further, a plurality of mounting supports are arranged on the inner side of the main housing assembly corresponding to any one of the mounting holes. A plurality of mounting brackets are correspondingly arranged on the rear cover plate of the camera lens. The plurality of mounting brackets are connected to the plurality of mounting supports one by one through fasteners to fixedly install the rear cover plate of the camera lens at the corresponding mounting hole.

[0019] Further, the detection camera further includes a sealing ring. A corresponding sealing groove is provided on the outer periphery of the front cover plate of the camera lens. The sealing ring is arranged in the sealing groove and is in sealing cooperation with the inner wall of the corresponding mounting hole.

[0020] Applying the technical solution of the present invention, a camera lens is provided. The camera lens includes a cover plate assembly, a housing assembly, and a lens assembly fixedly disposed within the housing assembly. The cover plate assembly includes a front cover plate and a rear cover plate that are snap-fitted to each other. The front cover plate and the rear cover plate form a spherical cavity when snap-fitted. At least a part of the housing assembly is disposed within the spherical cavity and is in limit fit with the inner wall of the spherical cavity. The fastening degree between the front cover plate and the rear cover plate is adjustable to clamp or loosen the housing assembly. The lens assembly has a lens end that protrudes from the housing assembly and the front cover plate. When the front cover plate and the rear cover plate loosen the housing assembly, the housing assembly can rotate to adjust the orientation of the lens end.

[0021] With this solution, when it is necessary to adjust the orientation of the lens end, the user only needs to loosen the front cover plate and the rear cover plate to loosen the housing assembly, and then can rotate the lens end protruding from the housing assembly and the front cover plate to realize the rotational adjustment of the lens assembly and the housing assembly, thereby realizing the adjustment of the orientation of the lens end. By setting in this way, using the adjustable fastening degree between the cover plate assembly and the housing assembly, and the limit fit between the housing assembly and the lens assembly, the lens assembly can rotate freely within the spherical cavity, thus realizing the rapid adjustment of the lens end orientation, avoiding the situation in the prior art where external auxiliary tools are required and / or the cover plate assembly needs to be removed to adjust the orientation of the lens end, simplifying the adjustment process and the time consumed for adjustment, saving the debugging time and labor costs. On the other hand, the lens end protrudes from the housing assembly and the front cover plate, avoiding the situation in the prior art where the lens is generally retracted inside the housing, restricting the field of view angle of the lens and making it difficult to adjust the lens due to the narrow operating space.

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation on the present invention and its application or use. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0052] As Figures 1 to 9 shown, an embodiment of the present invention provides a camera lens 10, which includes a cover plate assembly 11, a housing assembly 12, and a lens assembly 13 fixedly arranged in the housing assembly 12. The cover plate assembly 11 includes a front cover plate 111 and a rear cover plate 112 that are buckled with each other. The front cover plate 111 and the rear cover plate 112 are buckled to form a spherical cavity. The housing assembly 12 is at least partially arranged in the spherical cavity and is in limit fit with the inner wall of the spherical cavity. The fastening degree between the front cover plate 111 and the rear cover plate 112 is adjustable to clamp or loosen the housing assembly 12. The lens assembly 13 has a lens end that protrudes from the housing assembly 12 and the front cover plate 111. When the front cover plate 111 and the rear cover plate 112 loosen the housing assembly 12, the housing assembly 12 can rotate to adjust the orientation of the lens end.

[0053] When the camera lens 10 provided in this embodiment needs to adjust the orientation of the lens end, the user only needs to loosen the front cover plate 111 and the rear cover plate 112 to relax the two with respect to the housing assembly 12. After that, the rotation adjustment of the lens assembly 13 and the housing assembly 12 can be achieved by rotating the lens end protruding from the housing assembly 12 and the front cover plate 111, thereby realizing the adjustment of the orientation of the lens end. With such a setting, by utilizing the adjustable fastening degree between the cover plate assembly 11 and the housing assembly 12, and the limiting cooperation between the housing assembly 12 and the lens assembly 13, the lens assembly 13 can rotate freely within the spherical cavity, thus realizing the rapid adjustment of the orientation of the lens end. This avoids the situation in the prior art where external auxiliary tools are required and / or the cover plate assembly 11 needs to be removed to adjust the orientation of the lens end, simplifies the adjustment process and the time consumed for adjustment, and saves the debugging time and labor costs. On the other hand, the lens end protruding from the housing assembly and the front cover plate 111 are provided, avoiding the situation in the prior art where the lens is generally retracted inside the housing, which limits the field of view angle of the lens and makes it difficult to adjust the lens due to the narrow operating space.

[0054] Among them, the housing assembly 12 includes a front housing 121 and a rear housing 122. The front housing 121 and the rear housing 122 are buckled and fixedly connected through fasteners such as screws. The lens assembly 13 includes a lens module 131, a transparent window 132, and a lens cap 133. One end of the lens module 131 is fixedly arranged inside the housing assembly 12, and the end of the lens module 131 with the lens protrudes from the front housing 121 of the housing assembly 12. The transparent window 132 is installed at the end of the lens module 131 protruding from the housing assembly 12 through the lens cap 133 to form the lens end, and the lens module 131 is threadedly connected to the front housing 121.

[0055] In this embodiment, a first limiting structure 14 is provided between the inner side of the spherical cavity and the outer periphery of the housing assembly 12. The first limiting structure 14 is used to limit the rotation path of the housing assembly 12 within the spherical cavity. With such a setting, the rotation range of the housing assembly 12 can be restricted through the first limiting structure 14, ensuring that the orientation adjustment of the lens assembly 13 is within a preset range, avoiding lens damage or function failure caused by excessive rotation, improving the stability and safety of the lens assembly 13, and at the same time facilitating ensuring the accuracy of the orientation adjustment of the lens end.

[0056] Such as Figure 2 and Figure 9As shown in the figure, the first limiting structure 14 includes a limiting groove 141 provided on the outer periphery of the housing assembly 12 and a limiting protrusion 142 provided on the inner side of the front cover plate 111. The limiting protrusion 142 extends into the limiting groove 141 and is in limiting cooperation with a part of the inner wall of the limiting groove 141. At least part of the housing assembly 12 is a spherical housing whose shape is adapted to the spherical cavity. The extending direction of the limiting protrusion 142 coincides with a central axis of the housing assembly 12. When the front cover plate 111 and the rear cover plate 112 loosen the housing assembly 12, the position of the limiting protrusion 142 in the limiting groove 141 is adjustable and the limiting protrusion 142 can rotate in the limiting groove 141 to rotate the housing assembly 12 in different directions and adjust the orientation of the lens end.

[0057] In this embodiment, at least part of the housing assembly 12 is adapted to and in limiting cooperation with the spherical cavity to ensure the reliability and stability of the installation of the housing assembly 12 in the spherical cavity and avoid the situation of unstable installation such as the housing assembly 12 moving around in the spherical cavity. On the other hand, by restricting the extending direction of the limiting protrusion 142, it is ensured that the housing assembly 12 can rotate around the axis of the limiting protrusion 142 on the basis of its limiting cooperation with the inner wall of the spherical cavity. When the extending direction of the limiting protrusion 142 does not coincide with the central axis of the housing assembly 12, the rotation of the housing assembly 12 around the limiting protrusion 142 is an eccentric rotation, and the situation where the housing assembly 12 is affected by its limiting cooperation with the spherical cavity and cannot rotate around the axis of the limiting protrusion 142 is avoided, ensuring the adjustable range of the orientation of the lens end. Further, by adjusting the position of the limiting protrusion 142 in the limiting groove 141, the rotation adjustment of the lens end in another direction different from the rotation direction of the housing assembly 12 around the axis of the limiting protrusion 142 can be realized, further ensuring the adjustable range of the orientation of the lens end.

[0058] Specifically, the camera lens 10 has a first direction 101, a second direction 102 and a third direction 103 that are perpendicular to each other. The fastening direction of the front cover plate 111 and the rear cover plate 112 is the first direction 101. The radial cross-section of the housing assembly 12 where the second direction 102 and the third direction 103 are located is the first cross-section. The limiting groove 141 extends along the first direction 101 and passes through the first cross-section. The radial cross-section of the spherical cavity where the second direction 102 and the third direction 103 are located is the second cross-section. The limiting protrusion 142 extends along the second direction 102 and its axis is located on the second cross-section. When the front cover plate 111 and the rear cover plate 112 clamp the housing assembly 12, the first cross-section and the second cross-section coincide. When the front cover plate 111 and the rear cover plate 112 loosen the housing assembly 12, the first cross-section and the second cross-section coincide or are spaced apart. The limiting protrusion 142 is rotatably arranged in the limiting groove 141 to rotate and adjust the orientation of the lens end around the second direction 102, and the limiting protrusion 142 is movably arranged along the extending direction of the limiting groove 141 to adjust the orientation of the lens end around the third direction 103.

[0059] With such a setting, the lens assembly 13 and the housing assembly 12 can achieve "nodding" rotation and "shaking" rotation around the second direction 102 and the third direction 103, realizing the free rotation and precise adjustment of the lens assembly 13 in multiple directions, ensuring the flexibility and accuracy of the lens end orientation adjustment, and improving the multi-directional adjustment ability of the lens assembly 13.

[0060] It should be noted that in this embodiment, even when the front cover plate 111 and the rear cover plate 112 relax the housing assembly 12, the first cross-section and the second cross-section remain coincident or are only spaced apart by a distance that does not affect the movement and rotation of the limiting protrusion 142, so as to ensure the restriction of the limiting groove 141 on the limiting protrusion 142.

[0061] As Figure 9 shown, there are two sets of the first limiting structures 14, and the two sets of the first limiting structures 14 are symmetrically distributed about the center between the outer periphery of the housing assembly 12 and the inner side of the spherical cavity. With such a setting, the rotational stability and symmetry of the housing assembly 12 in the spherical cavity are further improved, ensuring the balance of the lens assembly 13 orientation adjustment, improving the rotational stability of the lens assembly 13, and making the orientation adjustment of the lens end smoother.

[0062] In this embodiment, the front cover plate 111 is rotatably arranged relative to the rear cover plate 112, and an adjusting structure 15 for adjusting the fastening degree between the two is arranged between the front cover plate 111 and the rear cover plate 112. When the front cover plate 111 rotates counterclockwise relative to the rear cover plate 112, the front cover plate 111 and the rear cover plate 112 approach each other and clamp the housing assembly 12 under the action of the adjusting structure 15. When the front cover plate 111 rotates clockwise relative to the rear cover plate 112, the front cover plate 111 and the rear cover plate 112 move away from each other and relax the housing assembly 12 under the action of the adjusting structure 15. With such a setting, by rotating the adjusting structure 15 counterclockwise and clockwise, the clamping and relaxation of the housing assembly 12 by the front cover plate 111 and the rear cover plate 112 are realized, thereby controlling the rotation and fixation of the lens assembly 13, providing a simple and effective lens assembly 13 rotation control mechanism, and making the adjustment of the lens end orientation convenient and safe.

[0063] As Figures 2 to 8As shown, the adjustment structure 15 includes a second limiting structure 151 and an abutting structure 152, the second limiting structure 151 is used to limit the relative position and relative rotation path of the front cover plate 111 and the rear cover plate 112; the abutting structure 152 has an abutting end and an abutting surface located on the side of the rear cover plate 112 away from the front cover plate 111, the abutting surface and the abutting end are respectively fixed relative to the rear cover plate 112 and the front cover plate 111, the abutting surface extends along the circumference of the cover plate assembly 11, and the distance between the abutting surface and the radial plane of the cover plate assembly 11 gradually increases in the counterclockwise rotation direction of the front cover plate 111 relative to the rear cover plate 112, the abutting end abuts against the abutting surface and the abutting position of the abutting end with the abutting surface in the extension direction of the abutting surface is adjustable.

[0064] In this embodiment, the user can rotate the front cover plate 111 to drive one of the abutting surfaces or the abutting ends to rotate relative to the rear cover plate 112 and the other of the abutting surface and the abutting end. Due to the abutment between the abutting surface and the abutting end and the inclined setting of the abutting surface, the relative distance between the front cover plate 111 and the rear cover plate 112 will change during the relative rotation process, thereby clamping or loosening the housing assembly 12. In this way, through the cooperation of the second limiting structure 151 and the abutting structure 152, the precise relative position control between the front cover plate 111 and the rear cover plate 112 is achieved, the stability of the housing assembly 12 during rotation is ensured, and the rotation accuracy and stability of the lens assembly 13 are improved.

[0065] It can be understood that the selection of the adjustment structure 15 can be adaptively selected according to actual conditions. Similarly, the corresponding relationship between counterclockwise rotation, clockwise rotation and clamping and loosening can also be adaptively adjusted.

[0066] Specifically, the second limiting structure 151 includes a limiting waist-shaped hole 1511 and a transfer shaft 1512. The limiting waist-shaped hole 1511 is arranged on the rear cover plate 112 and extends along the circumference of the rear cover plate 112. The transfer shaft 1512 is arranged on the side of the front cover plate 111 facing the rear cover plate 112 corresponding to the limiting waist-shaped hole 1511. The transfer shaft 1512 passes through the limiting waist-shaped hole 1511 and its position in the limiting waist-shaped hole 1511 is adjustable; the abutment structure 152 includes an abutment protrusion 1521 and an abutment block 1522. The abutment protrusion 1521 is located away from the rear cover plate 112 On one side of the front cover plate 111 and located on the inner side of the limiting waist-shaped hole 1511 close to the axial direction of the rear cover plate 112, the abutment surface is formed on the side of the abutment protrusion 1521 away from the rear cover plate 112, and the abutment block 1522 is arranged at the end of the transfer shaft 1512 away from the front cover plate 111, and the abutment block 1522 extends radially toward the axial direction of the front cover plate 111. The abutment end is formed on the plane of the abutment block 1522 toward the side of the front cover plate 111. When the abutment end abuts with the abutment surface, the abutment protrusion 1521 is located between the rear cover plate 112 and the abutment block 1522.

[0067] Such a configuration facilitates the forming of the abutting surface and the abutting end, and through the cooperation of the limiting waist-shaped hole 1511 and the adapter shaft 1512, as well as the abutting action of the abutting protrusion 1521 and the abutting block 1522, precise relative position control between the front cover plate 111 and the rear cover plate 112 is achieved, thereby ensuring the stability and accuracy of the shell assembly 12 during rotation, and improving the rotation accuracy and stability of the lens assembly 13.

[0068] It should be noted that the limiting waist-shaped hole 1511 includes a through hole section for passing the transfer shaft 1512 and the abutment block 1522 and a limiting hole section for limiting cooperation with the transfer shaft 1512. The through hole section and the limiting hole section are connected, and the extension direction of the abutment protrusion 1521 is parallel to the limiting hole section and is located on the inner side of the limiting hole section and one side of the through hole section. By setting the through hole section, it is convenient to disassemble and assemble the front cover plate 111 and the rear cover plate 112, and the convenience of disassembly and assembly is improved. It can be understood that when adjusting the fastening degree of the front cover plate 111 and the rear cover plate 112, the user can control the rotation range by himself to ensure that the abutment block 1522 is not directly opposite to the through hole section, which will cause the front cover plate 111 and the rear cover plate 112 to separate.

[0069] It is understandable that when the user rotates the front cover plate 111 , due to the extension of the limiting groove 141 , the front cover plate 111 will drive the housing assembly 12 to rotate together during the rotation process.

[0070] Furthermore, the abutting surface is provided with a first tooth structure along its extension direction, and the abutting end is provided with a second tooth structure 161 adapted to mesh with the first tooth structure, and the first tooth structure or the second tooth structure 161 is an elastic structure. Figure 4 , Figure 6 and Figure 8 As shown, in this embodiment, the second tooth structure 161 is an elastic structure. Through the elastic engagement of the first tooth structure and the second tooth structure 161, the self-locking function of the front cover plate 111 and the rear cover plate 112 during the adjustment process is realized, thereby preventing the lens assembly 13 from rotating accidentally during use. At the same time, it avoids the situation where the abutting end and the abutting surface are in hard abutment and the rotation is easy to cause damage to the structures of the two, thereby improving the stability of the lens assembly 13, and is suitable for occasions where it is necessary to prevent the lens from rotating accidentally during use.

[0071] There are multiple groups of adjustment structures 15, and the multiple groups of adjustment structures 15 are spaced and distributed between the front cover plate 111 and the rear cover plate 112 along the circumference of the cover plate assembly 11. There are three groups of adjustment structures 15 in this embodiment, and the three groups of adjustment structures are equally spaced and distributed along the circumference of the camera lens 10. In this way, through the arrangement of multiple groups of adjustment structures 15, the connection strength and stability between the front cover plate 111 and the rear cover plate 112 are enhanced, ensuring uniform force on the housing assembly 12 during rotation, and improving the rotation stability and service life of the lens assembly 13.

[0072] As Figure 2 , Figure 8 and Figure 9 shown, the camera lens 10 further includes a damping structure 17. The damping structure 17 includes a front damping silica gel member 171 and a rear damping silica gel member 172. The front damping silica gel member 171 is disposed within the front cover plate 111, and the rear damping silica gel member 172 is disposed within the rear cover plate 112. The cover plate assembly 11 clamps or relaxes the housing assembly 12 through the damping structure 17.

[0073] In this embodiment, the front damping silica gel member 171 can be snap-fitted within the front cover plate 111, and the rear damping silica gel member 172 can be snap-fitted within the rear cover plate 112 to ensure the fixation of the front damping silica gel member 171 relative to the front cover plate 111 and the fixation of the rear damping silica gel member 172 relative to the rear cover plate 112. Both the front damping silica gel member 171 and the rear damping silica gel member 172 are annular structures, and their shapes are adapted to the outer periphery of the housing assembly 12 and the inner wall of the spherical cavity. Through the elastic damping action of the front damping silica gel member 171 and the rear damping silica gel member 172, the clamping degree of the cover plate assembly 11 on the housing assembly 12 can be increased, further ensuring that the housing assembly 12 in the clamped state will not rotate by itself, which is beneficial to improving the reliability and stability of the clamping of the cover plate assembly 11 on the housing assembly 12. At the same time, the damping structure 17 can also provide sealing between the housing assembly 12 and the cover plate assembly 11, which is beneficial to improving the waterproof performance of the camera lens 10.

[0074] As Figure 1 , Figure 2 and Figure 5 shown, a wrench structure 181 is provided on the surface of the front cover plate 111 facing away from the rear cover plate 112, and two wrench structures 181 are symmetrically arranged along the circumferential direction of the front cover plate 111. Such an arrangement facilitates the rotation operation of the front cover plate 111 by the user, enabling the user to easily rotate the front cover plate 111 clockwise or counterclockwise, thereby controlling the rotation and fixation of the lens assembly 13 and improving the adjustment convenience of the lens assembly 13.

[0075] As Figures 10 to 12 shown, another embodiment of the present invention provides a detection camera. The detection camera includes an upper cover assembly 20, a control board assembly 30, a main housing assembly 40, a fill light assembly 50, a lamp housing assembly 60, and the above-mentioned camera lens 10. The upper cover assembly 20 and the main housing assembly 40 form a receiving cavity for placing the control board assembly 30 and the camera lens 10. The main housing assembly 40 has a plurality of mounting holes 401 in the circumferential direction, and a camera lens 10 is fixedly installed at any one of the mounting holes 401. The fill light assembly 50 is disposed within the lamp housing assembly 60, and the lamp housing assembly 60 is disposed at the bottom of the main housing assembly 40.

[0076] In this embodiment, the fill light assembly can emit a variety of lights, which can not only fill light for the lens, but also provide color guidance when the lens recognizes a parking space. Four mounting holes 401 are circumferentially and spacedly distributed on the main housing assembly 40, and a camera lens 10 is mounted at each mounting hole 401. The control board assembly 30 is electrically connected to all four camera lenses 10. By forming a receiving cavity through the upper cover assembly 20 and the main housing assembly 40, and by providing a plurality of mounting holes 401 on the main housing assembly 40, the integrated installation of the control board assembly 30 and the camera lens 10 is achieved. At the same time, through the settings of the fill light assembly 50 and the lamp shade assembly 60, a good fill light effect and waterproof performance are provided. Further, by utilizing the adjustable fastening degree between the cover plate assembly 11 and the housing assembly 12, and the limiting cooperation between the housing assembly 12 and the lens assembly 13, the lens assembly 13 can freely rotate in the spherical cavity, thereby realizing the rapid adjustment of the lens end orientation, avoiding the situation in the prior art where external auxiliary tools are needed and / or the cover plate assembly 11 needs to be removed from the main housing assembly 40 to adjust the orientation of the lens end, simplifying the adjustment process and the time consumed for adjustment, and saving the debugging time and labor costs.

[0077] Specifically, a plurality of mounting supports 41 are provided on the inner side of the main housing assembly 40 corresponding to any one of the mounting holes 401. A plurality of mounting brackets 182 are correspondingly provided on the rear cover plate 112 of the camera lens 10. The plurality of mounting brackets 182 are connected to the plurality of mounting supports 41 one by one through fasteners to fixedly mount the rear cover plate 112 of the camera lens 10 at the corresponding mounting hole 401. With such a setting, through the cooperation of the mounting support 41 and the mounting bracket 182, and the connection function of the fasteners, the stable installation of the rear cover plate 112 of the camera lens 10 on the main housing assembly 40 is achieved, ensuring the stability of the installation of the camera lens 10 when the lens assembly 13 is adjusted. Among them, the fasteners are fixing bolts or fixing screws, etc.

[0078] Preferably, a flanging structure 42 is provided on the inner side of the main housing assembly 40 corresponding to any one of the mounting holes 401. The flanging structure 42 is annular, and its inner wall is in limiting cooperation with the outer periphery of the cover plate assembly 11. With such a setting, the contact area between the camera lens 10 and the main housing assembly 40 is increased, improving the installation stability.

[0079] Further, the detection camera further includes a sealing ring 70. A corresponding sealing groove is provided on the outer periphery of the front cover plate 111 of the camera lens 10. The sealing ring 70 is arranged in the sealing groove and is in sealing cooperation with the inner wall of the corresponding mounting hole 401. With such a setting, the waterproof seal between the camera lens 10 and the main housing assembly 40 is further improved through the sealing ring 70, making the detection camera more applicable, not only for indoor use, but also for outdoor environments, ensuring the stable operation of the detection camera in outdoor environments.

[0080] In summary, the present invention provides a camera lens 10 and a detection camera, which can be used for parking space detection in a parking lot. When it is necessary to adjust the orientation of the lens end of the camera lens 10, the user can easily rotate the front cover plate 111 of the camera lens 10 clockwise through the wrench structure 181. Combining the second limiting structure 151 and the abutting structure 152 causes the damping structure 17 to loosen the housing assembly 12. Then, the user adjusts the lens assembly 13 to make it rotate in a "nodding" or "shaking" manner to adjust the orientation of its lens end. After the adjustment is completed, the user rotates the front cover plate 111 counterclockwise through the wrench structure 181. Combining the second limiting structure 151 and the abutting structure 152 causes the damping structure 17 to clamp the housing assembly 12 again to prevent the housing assembly 12 and the lens assembly 13 from rotating by themselves. With such a setting, through the unique cooperation design of the cover plate assembly 11 and the housing assembly 12, as well as the setting of the first limiting structure 14 and the adjusting structure 15, the function of quickly adjusting the orientation of the lens end without disassembling and using auxiliary tools is realized. When installing and debugging the lens end, there is no need to rely on tools and disassemble the camera lens 10. Directly rotating the front cover plate 111 and the lens assembly 13 can achieve loosening, adjusting, and fastening of the lens assembly 13, greatly saving time and labor costs and improving the efficiency of on-site debugging. Moreover, during the adjustment process, the cooperation of the second limiting structure 151 and the abutting structure 152 ensures precise relative position control between the front cover plate 111 and the rear cover plate 112, while the setting of the damping structure 17 provides a stable elastic damping force, making the rotation of the lens assembly 13 both precise and stable, and at the same time capable of providing a certain degree of waterproof ability for the camera lens 10. After the adjustment is completed, the elastic meshing effect of the first toothed structure and the second toothed structure 161 realizes the self-locking function of the lens assembly 13, preventing accidental rotation of the lens end during use and ensuring the accuracy and stability of parking space detection. On the other hand, by providing a plurality of mounting holes 401 on the main housing assembly 40, the detection camera can be compatible with different numbers of camera lenses 10, meeting the monitoring requirements in different scenarios and improving the flexibility and versatility of the detection camera. When used in an outdoor environment, the setting of the sealing ring 70 further improves the waterproof performance of the detection camera, enabling it to work stably under harsh weather conditions such as rain and snow, and improving the reliability and stability of the parking space detection system.
