Description

Technical Field

[0001] This utility model relates to the field of camera technology, and specifically to a camera with a universal mounting structure. Background Technology

[0002] A camera typically consists of two main parts: a housing and a lens module. After assembly, the lens module is fixed inside the housing using a support structure. Therefore, the housing and lens module are generally designed with a dedicated mating structure, resulting in poor housing versatility, a large number of housing molds, and high production costs. This application is based on this issue. Utility Model Content

[0003] The purpose of this utility model is to provide a camera with a reasonable structure, reliable use, and universal installation structure, which improves the versatility of the housing, makes it convenient and flexible to assemble with the lens module, and has a wide range of applications.

[0004] The technical solution of this utility model is:

[0005] A camera with a universal mounting structure includes a housing, a lens module, and a positioning assembly. The front face of the housing has a lens window. The key technical features are: four radial ridges are evenly distributed on the outer surface of the lens barrel of the lens module, extending axially from one end of the lens barrel to the other. Each radial ridge has an axial through hole, the cross-section of which extends radially along the lens barrel. The inner side of the front face of the housing has multiple axial struts evenly arranged around the center line of the lens window. The number of axial struts is equal to the number of radial ridges and corresponds one-to-one. The positioning assembly includes multiple positioning bolt assemblies disposed on the outer peripheral wall of the housing and corresponding to the axial struts. The width of the axial through hole is equal to the diameter of the axial strut.

[0006] The aforementioned camera with a universal mounting structure has a thickened boss on the outer peripheral wall of the housing corresponding to the positioning bolt assembly. The thickened boss has a radial threaded hole communicating with the inside of the housing. The positioning bolt assembly consists of a positioning bolt connected to the radial threaded hole and a locking nut on the positioning bolt.

[0007] The aforementioned camera with a universal mounting structure has eight positioning bolt assemblies, arranged in pairs. The two positioning bolt assemblies in the same group are spaced apart along the axial direction of the housing, and the four groups of positioning bolt assemblies are evenly arranged around the center line of the lens window.

[0008] The aforementioned camera with a universal mounting structure has a reference scale line at the outer edge of the radial convex ridge at the axial through hole, which facilitates the operator's observation of the position of the axial support rod in the axial through hole.

[0009] The camera with the universal mounting structure described above has a housing consisting of a main housing that houses the lens module, a top cover located at the front end of the main housing, and a tail cover located at the rear end of the main housing. The lens window is located at the center of the top cover, and the center of the tail cover has an external connector that connects to the output end of the lens module. The inner side of the tail cover also has a buffer assembly facing the top cover.

[0010] The aforementioned camera with a universal mounting structure comprises a fixed ring arranged concentrically with the external connector, an axial buffer spring connected to the fixed ring, and a push ring located at the free end of the axial buffer spring.

[0011] The camera with the universal mounting structure described above has two support bases spaced apart at the bottom of the housing.

[0012] The beneficial effects of this utility model are:

[0013] During assembly, first align the radial protrusions on the outer periphery of the lens barrel with the axial struts inside the housing, so that the axial through holes on the radial protrusions fit onto the corresponding axial struts. Then, push the lens to the front end of the housing to achieve pre-positioning. With the lens barrel at the center of the housing and aligned with the lens window, finally use the various positioning bolt assemblies to lock and position it. The assembly method of the lens barrel and housing of this utility model improves the versatility of the housing. The assembly of the housing and lens module is convenient and flexible, suitable for lens modules of different diameters and lengths, and has a wide range of applications.

[0018] The present invention will be described in detail with reference to the accompanying drawings.

[0019] like Figures 1-3 As shown, the camera with a universal mounting structure includes a housing 1, a lens module (lens assembly omitted in the figure) and a positioning assembly. The front end of the housing 1 is provided with a lens window 12.

[0020] The lens module's lens barrel 2 has four radial ridges 3 evenly distributed on its outer surface. The phase angle between two adjacent radial ridges 3 is 90 degrees. The radial ridges 3 extend axially from one end of the lens barrel 2 to the other. Each radial ridge 3 has an axial through hole 7, the cross-section of which extends radially along the lens barrel 2. The inner side of the front end face of the housing 1 has multiple axial struts 8 evenly arranged around the center line of the lens window 12. The number of axial struts 8 is equal to the number of radial ridges 3 and corresponds one-to-one. The width of the axial through hole 7 is equal to the diameter of the axial strut 8. In this embodiment, the radial ridges 3 have reference scale lines 9 at the outer edge of the axial through hole 7 to facilitate observation of the position of the axial strut 8 within the axial through hole 7. The end faces of the axial struts 8 are colored for easy observation.

[0021] The positioning assembly includes multiple positioning bolt assemblies disposed on the outer peripheral wall of the housing 1 and corresponding to the axial strut 8. In this embodiment, the outer peripheral wall of the housing 1 is provided with a thickened boss 6 corresponding to the positioning bolt assembly. The thickened boss 6 is provided with a radial threaded hole communicating with the interior of the housing 1. The positioning bolt assembly consists of a positioning bolt 5 connected to the radial threaded hole and a locking nut 4 disposed on the positioning bolt 5. There are eight positioning bolt assemblies, arranged in pairs. The two positioning bolt assemblies in the same pair are arranged at intervals along the axial direction of the housing 1, and the four pairs of positioning bolt assemblies are evenly arranged around the center line of the lens window 12.

[0022] The housing 1 comprises a main housing accommodating the lens module, a top cover 11 located at the front end of the main housing, and a tail cover 13 located at the rear end of the main housing. The lens window 12 is located at the center of the top cover 11. The tail cover 13 has an external connector 14 at its center that connects to the output end of the lens module. The inner side of the tail cover 13 also has a buffer assembly facing the top cover 11. In this embodiment, the buffer assembly consists of a fixing ring 15 arranged concentrically with the external connector 14, an axial buffer spring 16 connected to the fixing ring 15, and a push ring 17 located at the free end of the axial buffer spring 16. Two support seats 10 are spaced apart at the bottom of the housing 1.

[0023] Working principle:

[0024] First, align the radial protrusions 3 on the outer periphery of the lens barrel 2 with the axial struts 8 inside the housing 1, so that the axial through holes 7 on the four radial protrusions 3 fit onto the corresponding axial struts 8, and push the lens module to the front end of the housing 1. The four axial struts 8 together constrain the XY position of the lens barrel 2, so that the lens barrel 2 is located at the center of the housing 1, aligned with the lens window 12, and pre-positioning is achieved. Connect the external connector 14 to the output end of the lens module, then fasten the tail cap 13, and place the buffer assembly against the rear end of the lens module. Finally, use the various positioning bolt assemblies to achieve locking and positioning.

[0025] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this utility model.
