Description

Technical Field

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

[0002] With the increasing awareness of security and the development of intelligent technologies, cameras have been widely used in various scenarios, becoming core equipment for security monitoring and scene surveillance. Among them, outdoor cameras are becoming increasingly common due to their adaptability to monitoring needs in various outdoor scenarios such as home courtyards, shop perimeters, parks, construction sites, and orchards. Currently, most outdoor cameras on the market have features such as IP65 or higher dust and water resistance ratings, high-definition imaging, night vision, wireless transmission or 4G networking, and some are also equipped with solar power supply and intelligent detection functions to adapt to complex outdoor environments and diverse monitoring needs.

[0003] Because the outdoor environment is much harsher than the indoor environment, outdoor cameras are constantly exposed to the air and are highly susceptible to environmental factors such as wind, sand, dust, and floating dust. Dust will continuously accumulate on the lens surface, and even with basic dustproof designs, it is difficult to completely prevent dust accumulation. This accumulated dust will obstruct the lens, hinder light transmission, and damage the lens's optical imaging effect, resulting in problems such as blurry images, loss of detail, reduced contrast, and color distortion. This makes it impossible to clearly capture key information such as people and objects in the monitored area, greatly affecting the monitoring effectiveness of outdoor cameras. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a dustproof camera that solves the problem that dust easily accumulates on the surface of outdoor camera lenses, affecting optical imaging and causing blurry images.

[0005] According to an embodiment of the present invention, a dustproof camera includes a mounting housing and a second motor. The mounting housing accommodates a camera module. One end of the mounting housing is detachably provided with an end cap. The end cap has a through hole and a protective lens is provided at the through hole. A rotating ring is rotatably provided on the end face of the end cap away from the mounting housing. A mounting groove is provided on the circumferential inner wall of the rotating ring. A first motor is fixedly provided on the inner wall of the mounting groove. A scraper is fixedly provided on the output end of the first motor. The scraper is arc-shaped. A cleaning element is provided on the side of the scraper facing the protective lens. A second motor is embedded on the side of the end cap facing the rotating ring. A gear is provided on the output end of the second motor. An annular groove is provided on the side of the rotating ring facing the end cap. A gear ring is fixedly sleeved in the annular groove and meshes with the gear.

[0006] Compared with existing technologies, the present invention has the following advantages: by using an end cap and a mounting shell to form a receiving cavity for the camera module, a rotating ring is rotatably set on the end cap, and a scraper is fixedly set in the mounting groove of the rotating ring by a first motor. The rotation of the first motor controls the scraper to be in two states: storage and use. When cleaning, a second motor drives a gear ring to rotate through a gear, causing the rotating ring to rotate, thereby allowing the cleaning component on the scraper to sweep back and forth across the surface of the protective lens, thereby cleaning the dust accumulated on the protective lens. The dual protection of the protective lens and the cleaning component enables the camera module to obtain a clear image and ensures the reliability of monitoring.

[0007] Furthermore, the inner wall of the mounting groove is provided with a receiving groove for accommodating cleaning parts.

[0008] Furthermore, the bottom of the rotating ring on the side away from the end cap has a notch that communicates with the mounting groove.

[0009] Furthermore, the first motor is positioned in the middle of the inner wall of the mounting groove, and the scraper extends towards the top of the rotating ring.

[0010] Furthermore, the end cap has a groove on the side facing the mounting shell, and the inner wall of the groove has an internal thread. The mounting shell has a protrusion on the side facing the end cap that matches the groove, and the outer wall of the protrusion has an external thread that matches the internal thread.

[0011] Furthermore, the sidewalls of the groove and the opposite sides of the protrusion are provided with arc-shaped grooves, and a sealing ring is fitted between the two arc-shaped grooves.

[0012] Furthermore, at least one sliding groove is provided on the end face of the end cap facing the mounting shell, and a pin is slidably provided in each sliding groove. A clearance groove communicating with the sliding groove is provided on the circumferential side wall of the end cap, and a push block is slidably provided in the clearance groove. The push block is fixedly connected to the pin. An insertion hole for the pin to be inserted is provided on the end face of the mounting shell facing the end cap.

[0013] Furthermore, it also includes a spring, one end of which is fixedly connected to the inner wall of the groove, and the other end of which is fixedly connected to a pin.

[0014] Furthermore, a wire hole communicating with the interior is provided at the end of the mounting shell away from the end cap, and a corrugated tube is fixedly inserted through the wire hole. Attached Figure Description

[0022] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 5 As shown, this embodiment of the invention proposes a dustproof camera, including a mounting shell 1 and a second motor 9. The mounting shell 1 is used to accommodate the camera module 2. One end of the mounting shell 1 is detachably provided with an end cap 3. The end cap 3 has a through hole, and a protective lens 4 is provided at the through hole. A rotating ring 5 is rotatably provided on the end face of the end cap 3 away from the mounting shell 1. A mounting groove is provided on the circumferential inner wall of the rotating ring 5. A first motor 6 is fixedly provided on the inner wall of the mounting groove. A scraper 7 is fixedly provided on the output end of the first motor 6. The scraper 7 is arc-shaped. A cleaning component 8 is provided on the side of the scraper 7 facing the protective lens 4. The second motor 9 is embedded on the side of the end cap 3 facing the rotating ring 5. A gear 10 is provided on the output end of the second motor 9. An annular groove is provided on the side of the rotating ring 5 facing the end cap 3. A gear ring 11 is fixedly sleeved in the annular groove, and the gear ring 11 meshes with the gear 10.

[0024] In this embodiment, the mounting shell 1 and the end cap 3 are connected to form a chamber for accommodating the camera module 2. The inner wall of the mounting shell 1 is adapted to the shape of the camera module 2. The lens of the camera module 2 faces the protective lens 4, and the protective lens 4 is fixed on the end cap 3 and protrudes towards the rotating ring 5, and is basically at the same horizontal plane as the scraper 7, so that the cleaning component 8 can glide across its surface. The camera is fixed to a predetermined outdoor position by a bracket. When no cleaning operation is being performed, the scraper 7 is stored in the mounting groove. The scraper 7 is arc-shaped and can be well stored in the mounting groove so that it does not obstruct the view of the camera module 2. Both the first motor 6 and the second motor 9 can be controlled by existing control methods such as PLCs and microcontrollers to rotate forward and backward, adjust their rotation angle, and start and stop. Their power supply can be a battery or other existing power source. The first motor 6 is a self-locking motor. When cleaning the protective lens 4, the first motor 6 is started, rotating the scraper 7 by a certain angle, causing it to slide out of the mounting slot. The straight-line length of the scraper 7 should be greater than the radius of the protective lens 4. The second motor 9 is started, driving the gear 10 to rotate, which in turn drives the meshing gear ring 11 to rotate, causing the rotating ring 5 to rotate on the end face of the end cover 3. This allows the cleaning element 8 on the scraper 7 to scrape away dust from the protective lens 4. The cleaning element 8 can be selected from existing materials, such as sponge or fiber cloth, preferably materials with good deformation capabilities. After cleaning, the second motor 9 stops rotating, and the first motor 6 restarts, driving the scraper 7 to rotate back into the mounting slot for storage. Through the cooperation of the first motor 6, the second motor 9, and the rotating ring 5 with the mounting slot, the outdoor camera can be cleaned in a timely, remote and convenient manner, keeping the lens of the camera module 2 clean and enabling the camera module 2 to capture clear images, thereby ensuring the reliability of monitoring.

[0025] like Figure 6 As shown, furthermore, a receiving groove 12 is provided on the inner wall of the mounting groove for accommodating the cleaning component 8. The cleaning component 8 is preferably a cleaning material with a certain deformation capability. The receiving groove 12 is provided on the inner wall of the mounting groove facing it. When the scraper 7 is stored in the mounting groove of the rotating ring 5, the cleaning component 8 is stored in the receiving groove 12. This protects the cleaning component 8 when it is not in use, preventing it from being corroded by outdoor wind and sand, thereby extending the service life of the cleaning component 8 and reducing the replacement cycle of the cleaning component 8.

[0026] like Figures 1 to 4As shown, furthermore, the bottom of the rotating ring 5 on the side away from the end cap 3 is provided with a notch 13 communicating with the mounting groove. In this embodiment, when the protective lens 4 is not being cleaned, the rotating ring 5 returns to the zero position. At this time, the notch 13 on the rotating ring 5 is located at the bottom. The notch 13 allows cleaning dust and dust that has drifted onto the protective lens 4 from outdoors to be discharged through the notch 13 of the rotating ring 5 under the action of gravity. The semi-enclosed structure formed by the rotating ring 5 with the notch 13 can also provide a certain dustproof effect for the protective lens 4.

[0027] like Figure 4 As shown, the first motor 6 is further positioned in the middle of the inner wall of the mounting groove, and the scraper 7 extends towards the top of the rotating ring 5. Specifically, when the camera module 2 is in use and the scraper 7 is in the zero position, the scraper 7 is located in the top area of ​​the rotating ring 5. With this arrangement, when external sand and dust pass through the rotating ring 5, only a very small amount of sand and dust will fly over the area where the scraper 7 is located, thereby reducing the contamination of the cleaning components 8 on the scraper 7 by sand and dust.

[0028] like Figure 2 and Figure 6 As shown, the end cap 3 has a groove on the side facing the mounting housing 1, and the inner wall of the groove has an internal thread. The mounting housing 1 has a protrusion 14 on the side facing the end cap 3 that matches the groove, and the outer wall of the protrusion 14 has an external thread that matches the internal thread. In this embodiment, the end cap 3 is threadedly connected to the mounting housing 1. After installation, the protrusion 14 will extend into the groove, extending the path for external dust to enter the mounting housing 1, further preventing external wind and sand from corroding the camera module 2.

[0029] like Figure 2 and Figure 6 As shown, furthermore, arc-shaped grooves are provided on the opposite sides of the groove sidewall and the protrusion 14, and a sealing ring 15 is fitted between the two arc-shaped grooves. The sealing ring 15 blocks the channel for external access into the mounting housing 1, ensuring that the core camera module 2 inside the camera will not be corroded by wind and sand during long-term outdoor operation.

[0030] like Figure 6As shown, further, at least one sliding groove is provided on the end face of the end cap 3 facing the mounting shell 1, and a pin 16 is slidably provided in each sliding groove. A clearance groove communicating with the sliding groove is provided on the circumferential side wall of the end cap 3, and a push block 17 is slidably provided in the clearance groove. The push block 17 is fixedly connected to the pin 16. An insertion hole for the pin 16 to be inserted is provided on the end face of the mounting shell 1 facing the end cap 3. In this embodiment, two sliding grooves are symmetrically provided on the end face of the end cap 3, and a pin 16 is slidably provided in each sliding groove through the push block 17. Correspondingly, an insertion hole for the pin 16 to be inserted is also symmetrically provided on the end face of the mounting shell 1. By pushing the pin 16 from the outside, the operator can insert the pin 16 into the insertion hole, restricting the relative rotation between the end cap 3 and the mounting shell 1, effectively preventing the relative rotation between the end cap 3 and the mounting shell 1 under the interference of external factors, thereby making the first motor 6, the second motor 9 and the entire camera device more stable during operation. In this embodiment, the pin 16 will not come out of the socket due to static friction.

[0031] like Figure 6 As shown, it further includes a spring 18, one end of which is fixedly connected to the inner wall of the slide groove, and the other end of which is fixedly connected to the pin 16. By providing the spring 18 in the slide groove, the spring 18 pushes the pin 16 to be continuously inserted into the insertion hole of the mounting housing 1. Preferably, the push block 17 extends away from the mounting housing 1, thereby shielding the entire slide groove and protecting the spring 18 located in the slide groove.

[0032] like Figure 1 As shown, furthermore, the end of the mounting housing 1 furthest from the end cap 3 has a wire hole communicating with its interior, and a corrugated tube 19 is fixedly inserted through the wire hole. The wire hole facilitates the power cord to pass through, and the setting of the corrugated tube 19 changes the position of the channel opening communicating with the interior of the mounting housing 1 from the outside. The operator can place the end of the corrugated tube 19 furthest from the mounting housing 1 in an area less susceptible to wind and dust erosion, thereby preventing external wind and sand from entering the mounting housing 1.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
