Description

Technical Field

[0001] This invention relates to the field of camera technology, and in particular to a waterproof and dustproof camera. Background Technology

[0002] Currently, there are two main types of cameras used for parking lot monitoring and management on the market. One type has its lens housed in a protective casing, with light passing through the casing at the corresponding position of the lens. These cameras offer good waterproof and dustproof performance, but the protective casing is difficult to disassemble and install, making lens angle adjustment inconvenient.

[0003] Another type of camera has its lens exposed outside the protective housing. After the camera is mounted in a fixed position, the lens can be squeezed by hand to apply force, which actuates the passive angle adjustment mechanism inside the housing, changing its orientation and ultimately aligning the lens with the shooting area. While this type of camera offers relatively convenient lens angle adjustment, the operator needs to manually manipulate the lens to change the passive angle adjustment mechanism, which can easily contaminate the lens and affect the camera's image quality. Furthermore, since the lens of this type of camera is exposed outside the housing, it is susceptible to dust and moisture contamination, affecting both image quality and lens lifespan.

[0004] Therefore, neither of the above two types of cameras can adequately balance waterproof and dustproof performance with the convenience of lens angle adjustment. Summary of the Invention

[0005] The purpose of this invention is to provide a waterproof and dustproof camera that better balances waterproof and dustproof performance with the convenience of lens angle adjustment.

[0006] Specifically, the technical solution of the present invention is:

[0007] A waterproof and dustproof camera includes a protective housing, a lens, and a passive angle adjustment mechanism. The lens is located inside the protective housing and mounted on the passive angle adjustment mechanism. The protective housing has a detachable end cap, which is sealed to the protective housing. The passive angle adjustment mechanism has an operating component, at least a portion of which protrudes from the protective housing as an operable part into the space between the protective housing and the end cap.

[0008] Furthermore, the passive angle adjustment mechanism is located inside the protective housing, and the protective housing has mounting holes at the positions corresponding to the passive angle adjustment mechanism. The operating component is connected to the passive angle adjustment mechanism through the mounting holes.

[0009] Furthermore, the passive angle adjustment mechanism is a two-axis rotating passive angle adjustment mechanism, including a first mounting base with a first rotating shaft and a second mounting base with a second rotating shaft. The first mounting base can rotate relative to the protective shell around the first rotating shaft. The second mounting base is rotatably connected to the first mounting base to rotate relative to the first mounting base around the second rotating shaft. The lens is fixed on the second mounting base. The first rotating shaft and the second rotating shaft are arranged intersectingly. The operating component further includes a first transmission component and a second transmission component, wherein the first transmission component is tractively connected to the first mounting base, and the second transmission component is tractively connected to the second mounting base, so as to drive the lens to rotate around the first rotating shaft and the second rotating shaft respectively through the first transmission component and the second transmission component.

[0010] Furthermore, the first transmission component includes a first operating part and a guide part. The first operating part is connected to the first mounting base through the guide part. The first operating part is located between the protective shell and the end cover. The mounting hole includes a guide hole with an arc-shaped structure. The guide part passes through the guide hole. The guide hole guides the guide part, causing the first transmission component to drive the first mounting base to rotate around the first rotating shaft.

[0011] Furthermore, the first operating part is a turntable, the guide part is integrally connected to the first operating part, and the first transmission component includes at least two guide parts, which are elastically engaged with the first mounting base.

[0012] Furthermore, the second transmission component includes a second operating part and two shafts, with the two shafts respectively disposed on both sides of the second operating part. A portion of the second operating part protrudes from the protective shell into the space between the protective shell and the end cap. A first mounting base is provided with a first clearance hole corresponding to the second operating part, and the mounting hole also includes a second clearance hole. The second operating part is sequentially connected to the second mounting base through the second clearance hole and the first clearance hole. A bearing is provided on the protective shell corresponding to the shaft, and the bearing is used to limit the shaft so that the second operating part and the second mounting base remain in contact.

[0013] Furthermore, the first operating part is provided with a third clearance hole corresponding to the second operating part, and the second operating part is connected to the second mounting base in sequence through the third clearance hole, the second clearance hole and the first clearance hole, and a part of the second operating part protrudes from the first operating part to the space between the first operating part and the end cover.

[0014] Furthermore, the second operating part is a roller, and the second operating part is connected to the second mounting base by friction drive.

[0015] Furthermore, the protective shell has a light-transmitting part corresponding to the lens, and the light-transmitting part is integrally and sealed with the protective shell.

[0016] Furthermore, the waterproof and dustproof camera includes two lenses and two passive angle adjustment mechanisms. The two lenses are arranged back to back and are respectively mounted on different passive angle adjustment mechanisms.

[0017] Beneficial technical effects of the present invention:

[0018] The lens of the waterproof and dustproof camera provided by this invention is housed within a protective housing. After removing the end cap located outside the housing, the operating mechanism is exposed. The operator manipulates this mechanism to change the posture of the passive angle adjustment mechanism, thereby altering the lens angle. Operation is convenient. During lens angle adjustment, the operator does not need to directly contact the lens. The lens is protected by the housing during both lens angle adjustment and normal camera operation, preventing exposure to the external environment and thus reducing the risk of contamination. Therefore, the waterproof and dustproof camera provided by this invention effectively balances waterproof and dustproof performance with convenient lens angle adjustment. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] In one embodiment, such as Figures 1 to 7As shown, the waterproof and dustproof camera provided by the present invention includes a protective housing 1, a lens 2, and a passive angle adjustment mechanism. The lens 2 is located inside the protective housing 1 and is mounted on the passive angle adjustment mechanism. A detachable end cap 3 is provided on the protective housing 1, and the end cap 3 is sealed to the protective housing 1. Specifically, the seal can be achieved by providing a waterproof sealing ring or similar device between the end cap 3 and the protective housing 1. The passive angle adjustment mechanism is provided with an operating component. At least a portion of the operating component protrudes from the protective housing 1 into the space between the protective housing 1 and the end cap 3, allowing the passive angle adjustment mechanism to be operated by removing the end cap 3 after removing the end cap 3. This changes the orientation of the passive angle adjustment mechanism, thereby adjusting the shooting angle of the lens 2.

[0028] In this embodiment, the passive angle adjustment mechanism is located inside the protective housing 1. The protective housing 1 has mounting holes (specifically, guide holes D and second clearance holes B) at the position corresponding to the passive angle adjustment mechanism. The operating component is connected to the passive angle adjustment mechanism through the mounting holes. By transmitting power to the passive angle adjustment mechanism through the operating component, the posture of the passive angle adjustment mechanism is changed, thereby changing the shooting angle of the lens 2. In other embodiments, the operating component may also be an extended operating lever integrally connected to the passive angle adjustment mechanism, rather than necessarily being a separate functional component connected to the passive angle adjustment mechanism.

[0029] In this embodiment, the passive angle adjustment mechanism is a two-axis rotating passive angle adjustment mechanism, including a first mounting base 41 with a first rotating shaft i and a second mounting base 42 with a second rotating shaft j, as shown below. Figure 4 As shown, the first mounting base 41 can rotate relative to the protective shell 1 about the first rotating axis i; the second mounting base 42 is rotatably connected to the first mounting base 41 to rotate relative to the first mounting base 41 about the second rotating axis j; the lens 2 is fixed on the second mounting base 42; the first rotating axis i and the second rotating axis j are arranged intersectingly; the operating components include a first transmission component 43 and a second transmission component 44, wherein the first transmission component 43 is drivenly connected to the first mounting base 41, and the second transmission component 44 is drivenly connected to the second mounting base 42, so that the lens 2 can be driven to rotate about the first rotating axis i and the second rotating axis j respectively through the first transmission component 43 and the second transmission component 44. In this embodiment, the lens 2 has two degrees of freedom, which can meet most shooting requirements. In other embodiments, the passive angle adjustment mechanism and the operating components can also have other structures. For example, when the lens 2 has fewer degrees of freedom (the lens 2 can only rotate about one axis) or more (the lens 2 can rotate about three axes), the structure of the passive angle adjustment mechanism and the operating components can be simpler or more complex.

[0030] In this embodiment, as Figure 3 and 7As shown, the first transmission member 43 includes a first operating part 431 and a guide part 432. The first operating part 431 is connected to the first mounting base 41 through the guide part 432. The first operating part 431 is located between the protective shell 1 and the end cover 3. The protective shell 1 is provided with a guide hole D corresponding to the guide part 432. The guide hole D has an arc-shaped structure, and the guide part 432 passes through the guide hole D. The guide part 432 is guided by the guide hole D, so that the first transmission member 43 drives the first mounting base 41 to rotate around the first rotating shaft i.

[0031] In this embodiment, the first operating part 431 is a turntable, and the guide part 432 is integrally connected to the first operating part 431. The first transmission member 43 includes at least two guide parts 432. The first mounting base 41 is provided with snap-fit ​​holes E corresponding to the guide parts 432. The guide parts 432 are elastically snapped into the first mounting base 41 for easy assembly. The operator can rotate the first transmission member 43 by turning the first operating part 431 with a single finger (rotation direction as shown). Figure 7 (As indicated by the double arrows), it drives the first mounting base 41 to rotate around the first rotating shaft i. In other embodiments, the first transmission member 43 can also be other structures, such as an operating lever fixed on the first mounting base 41, which can drive the first mounting base 41 to rotate around the first rotating shaft i by operating the first transmission member 43.

[0032] In this embodiment, the guide portion 432 specifically includes two pins integrally connected to the first operating portion 431. The two pins are elastic, and the free ends of the pins are provided with hooks for hooking the first mounting base 41. In other embodiments, the first operating portion 431 may also achieve a fixed connection with the first mounting base 41 through only one guide portion 432.

[0033] In this embodiment, as Figure 5 As shown, the second transmission component 44 includes a second operating part 441 and two shaft parts 442. The two shaft parts 442 are respectively located on both sides of the second operating part 441. A portion of the second operating part 441 protrudes from the protective shell 1 into the space between the protective shell 1 and the end cover 3. The first mounting base 41 is provided with a first clearance hole A corresponding to the second operating part 441, and the protective shell 1 is provided with a second clearance hole B corresponding to the second operating part 441. The second operating part 441 is connected to the second mounting base 42 in sequence through the second clearance hole B and the first clearance hole A. The protective shell 1 is provided with a bearing seat 12 corresponding to the shaft part 442. The bearing seat 12 is used to limit the shaft part 442, so that the second operating part 441 and the second mounting base 42 are in contact. The operator can turn the second operating part 441 with one finger to rotate the second transmission component 44 (rotation direction as shown). Figure 6(As indicated by the double-headed arrow). In other embodiments, the second transmission member 44 may also be of other structures, such as an operating lever fixedly connected to the second mounting base 42, which can drive the second mounting base 42 to rotate around the second rotating shaft j by operating the second transmission member 44.

[0034] In this embodiment, the second operating part 441 is a roller, and the second operating part 441 is connected to the second mounting base 42 by friction transmission. When the operating force is applied to the second operating part 441 to rotate the second transmission member 44, the second operating part 441 drives the second mounting base 42 to rotate around the second rotating shaft j through friction. A silicone layer can be provided on the surface of the roller 441 to increase the friction between the roller 441 and the second mounting base 42. In other embodiments, the second operating part 441 can also be a gear, driving the second mounting base 42 to rotate through gear transmission. However, since a rack needs to be provided on the second mounting base 42, the structure is more complex than this embodiment.

[0035] In this embodiment, the first operating part 431 is provided with a third clearance hole C corresponding to the second operating part 441. The second operating part 441 is sequentially connected to the second mounting base 42 through the third clearance hole C, the second clearance hole B, and the first clearance hole A. A portion of the second operating part 441 protrudes from the first operating part 431 between the first operating part 431 and the end cover 3. The second transmission member 44 is nested within the first transmission member 43, resulting in a compact structure. In other embodiments, the second transmission member 44 and the first transmission member 43 may also be provided separately.

[0036] In this embodiment, a light-transmitting part 13 is provided on the protective shell 1 corresponding to the lens 2. The light-transmitting part 13 is integrally and sealed with the protective shell 1. Specifically, the light-transmitting part 13 is an arc-shaped light-transmitting plastic plate. The light-transmitting plastic plate is integrally embedded on the protective shell 1 by injection molding, so that the light-transmitting plastic plate and the protective shell 1 are integrally and sealed to ensure good waterproof and dustproof effect.

[0037] In this embodiment, the waterproof and dustproof camera includes two lenses 2 and two passive angle adjustment mechanisms. The two lenses 2 are arranged back to back and are respectively mounted on different passive angle adjustment mechanisms, which can meet most shooting needs. In other embodiments, the number of lenses 2 may be fewer or more.

[0038] In this embodiment, a mounting base 5 is installed on the protective shell 1, and the waterproof and dustproof camera is fixed in the required position by the mounting base 5.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. It should be noted that any modifications, equivalent substitutions, or improvements made by those skilled in the art within the spirit and principles of the present invention after reading this specification should be included within the scope of protection of the present invention.
