Abstract
Description
Technical Field
[0001] This utility model relates to the field of photography, and in particular to a self-cleaning camera cover. Background Technology
[0002] Currently, cameras are widely used in both indoor and outdoor scenarios to assist in target monitoring and other functions. However, regardless of whether they are indoors or outdoors, cameras are easily contaminated by dust and other dirt, affecting the clarity of the images captured. Therefore, current cameras are usually sealed in protective housings, with the camera lens capturing images of external targets through a lens mounted on the housing. However, dust and other dirt still adhere to the outer surface of the lens, affecting the clarity of the camera's images, necessitating regular cleaning. However, these cameras are usually installed in high positions, requiring personnel to climb and work at height, making cleaning difficult and posing a safety risk. Products on the market now use wipers or similar brushing mechanisms to clean the outer surface of the lens. However, to ensure effective cleaning, these products require frequent reciprocating motion of the brushing mechanism to repeatedly scrub away dirt. This can obstruct the lens during cleaning, potentially causing the camera to miss images due to obstructed view, resulting in significant inconvenience. Utility Model Content
[0003] Therefore, the purpose of this utility model is to provide a self-cleaning camera cover, which has the advantages of being self-cleaning and unobstructed.
[0004] A self-cleaning camera cover includes a housing, a cover assembly, and a drive assembly. The housing is used to house a camera. The cover assembly covers the opening of the housing. The cover assembly includes a cover body, a sliding seat, a lens, and a scraper. The cover body has a through hole corresponding to the camera lens. The sliding seat is covered at the through hole. The drive assembly is disposed on the housing and drives the sliding seat to move along its length. The sliding seat has a mounting hole. The lens is disposed in the mounting hole. The length of the lens is greater than twice the maximum length of the through hole. Two sets of scrapers are respectively disposed on both sides of the through hole along the moving direction of the sliding seat. The scrapers are used to clean the lens.
[0005] This invention discloses a self-cleaning camera cover that eliminates the need for manual cleaning, saving significant manpower and material costs. Simultaneously, the movement of the lens allows the scraper to clean dirty areas without obstructing the camera lens, ensuring that the camera lens can still capture and inspect external targets through the lens and through-hole during the cleaning process.
[0006] Furthermore, the drive assembly comprises two sets symmetrically arranged on both sides of the sliding seat, each including a motor and a drive wheel. The drive wheel is mounted on the output shaft of the motor, and the sliding seat frictionally abuts against the drive wheel. This structure allows the sliding seat to slide autonomously, achieving automatic cleaning.
[0007] Furthermore, the drive assembly comprises two sets symmetrically arranged on both sides of the sliding seat, each including a motor and a gear. The gear is mounted on the output shaft of the motor, and the sliding seat has a rack that meshes with the gear. This structure improves drive stability and allows control of the sliding stroke of the sliding seat by the number of motor revolutions.
[0008] Furthermore, the sliding seat includes a seat body and a guide slide plate disposed on the seat body. The guide slide plate extends along the length direction. The cover body is provided with a guide rail that cooperates with the guide slide plate. The seat body is provided with a clearance cavity communicating with the mounting hole. The scraper extends into the clearance cavity to abut against the lens. This structure can guide and limit the sliding seat.
[0009] Furthermore, a sealing ring is provided between the sliding seat and the cover. This structure achieves waterproofing.
[0010] Furthermore, the bottom of the clearance cavity is a sloping surface that rises from the outside to the inside. This structure facilitates the drainage of excess water.
[0011] Furthermore, the cover assembly also includes a spray head and a water pipe. The spray head passes through the side of the sliding seat and faces the scraper. The connection between the spray head and the sliding seat is sealed. One end of the water pipe is connected to the spray head, and the other end is connected to the liquid storage tank. This structure can remove stubborn stains.
[0012] Furthermore, the lens and through-hole are rectangular. This structure is compatible with various types of cameras.
[0013] Furthermore, the cover is fixedly connected to the housing by screws. This structure allows for a detachable connection between the cover and the housing.
[0014] Furthermore, a drying box is provided inside the housing. This structure can keep the inside of the housing dry.
[0015] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example 1
[0026] Please see Figure 1-6 , Figure 1 An exploded view of the entire camera housing; Figure 2 This is a front view of the housing; Figure 3 For the housing along Figure 2 A cross-sectional view along direction AA as shown; Figure 4 This is a front view of the sliding seat; Figure 5 For the sliding seat edge Figure 4 A cross-sectional view along the BB direction shown; Figure 6 This is a schematic diagram showing the cooperation between the sliding seat and the drive assembly.
[0027] This utility model discloses a self-cleaning camera cover, including a housing 1, a cover assembly, and a drive assembly 3. The inner cavity of the housing 1 is used to house a camera 4, thereby preventing the camera 4 from being damaged by external forces in the field. The inner cavity has an opening at the end near the lens of the camera 4, and the cover assembly is placed over the opening end of the housing 1, thereby sealing the camera 4 inside the housing 1. The lens of the camera 4 corresponds to the cover assembly, thereby allowing monitoring and filming of the outside world through the cover assembly.
[0028] The cover assembly includes a cover body 21, a sliding seat 22, a viewing lens 23, and a scraper 24. The cover body 21 is fixedly connected to the housing 1 by screws. A through hole 211 corresponding to the camera lens is provided on the cover body 21, through which the camera lens monitors and captures images of the outside world. The size of the through hole 211 can be determined according to the parameters of the camera 4. In this embodiment, the through hole 211 is rectangular, but it can also be designed in other shapes. A sliding seat 22 is provided covering the through hole 211. The sliding seat 22 is located inside the cover body 21, i.e., closer to the camera 4, and can reciprocate relative to the through hole 211. In this embodiment, the sliding seat 22 moves laterally (i.e., left and right), but in practice, the sliding seat 22 can also move vertically up and down.
[0029] To guide and limit the sliding direction of the sliding seat 22, the sliding seat 22 includes a seat body 221 and guide slide plates 222 disposed on the upper and lower sides of the seat body 221. The guide slide plates 222 extend along the length direction (i.e., the left-right direction in this embodiment). The cover body 21 is provided with a guide rail 212 that cooperates with the guide slide plate 222. The guide rail 212 is L-shaped, and a groove 213 is formed between the L-shaped structure and the cover body 21. The guide slide plate 222 is slidably inserted into the groove 213, so that the sliding seat 22 can only slide along the guide rail 212. The sliding seat 22 is provided with an assembly hole 223, which is rectangular. The viewing mirror 23 is disposed in the assembly hole 223 and has a rectangular structure that is interference-fitted with the assembly hole 223.
[0030] The length of the perspective lens 23 along the moving direction needs to be greater than twice the maximum length of the through hole 211 along that moving direction. Therefore, when there is dirt in the area to the left of the perspective lens 23, the perspective lens 23 moves to the left, causing that area to rub against the scraper 24, thereby removing the dirt. At this time, the camera 4 can then capture images of the external environment through the area to the right of the perspective lens 23. Similarly, please refer to... Figure 7 , Figure 7 This is a schematic diagram showing the sliding seat 22 sliding to the right when there is dirt on the right side of the iris 23. When there is dirt on the right side of the iris 23, it can be cleaned by driving the iris 23 to move to the right.
[0031] To ensure cleaning effectiveness, when the area containing dirt comes into contact with the scraper 24, the drive assembly 3 can cause the lens 23 to move back and forth within a small range, allowing the scraper 24 to repeatedly scrub the dirt and improve the cleaning effect. This ensures that all parts of the lens 23 are cleaned while maintaining unobstructed access between the camera 4 and the external environment, allowing the camera 4 lens to perform continuous monitoring.
[0032] The driving assembly 3 is mounted on the housing 1 and drives the sliding seat 22 to move along its length. Two sets of the driving assembly 3 are symmetrically arranged on the upper and lower sides of the sliding seat 22. Each set includes a motor 31 and a driving wheel 32, with the driving wheel 32 mounted on the output shaft of the motor 31. In this embodiment, the upper and lower sides of the seat 221 rub against the driving wheel 32. The driving wheel 32 can be made of a material with a high coefficient of friction (such as rubber). Therefore, when the driving wheel 32 rotates, the sliding seat 22 moves to the left or right under the action of friction.
[0033] The seat 221 has a recessed cavity 224 communicating with the mounting hole 223. The mounting hole 223 is located at the bottom of the recessed cavity 224, thus forming an inwardly recessed structure to reduce the adhesion of external moisture or dust to the lens 23. Two sets of scrapers 24 are respectively arranged on both sides of the through hole 211 along the moving direction of the sliding seat 22. The scrapers 24 extend into the recessed cavity 224 to abut against the lens 23 for cleaning the lens 23.
[0034] The cover assembly also includes a spray head 25 and a water pipe. The spray head 25 passes through the side of the sliding seat 22 and faces the scraper 24. The connection between the spray head 25 and the sliding seat 22 is sealed to prevent water leakage. One end of the water pipe is connected to the spray head 25, and the other end is connected to a liquid storage tank. The liquid storage tank can be installed in the housing 1 or outside the cover.
[0035] To prevent cleaning fluid from flowing into the housing 1 and to maintain the humidity of the operating environment of the camera 4, a sealing ring 5 is provided between the sliding seat 22 and the cover 21, and the bottom of the clearance cavity 224 is an inclined surface that rises from the outside to the inside, so that water flows out through the through hole 211 along the inclined surface.
[0036] A drying box is also provided inside the housing 1 to ensure the dryness of the interior of the housing 1.
[0037] The housing 1 also houses a control module. This module determines the cleanliness of the lens 23 based on the image captured by the camera. When dirt on the lens 23 affects the shooting effect, the motor 31 is activated, causing the sliding base 22 to slide. This moves the lens 23 to the area containing the dirt, which is then brushed by the scraper 24. When the dirt is difficult to remove, the spray head 25 is activated to spray cleaning fluid, thereby improving cleaning efficiency.
[0038] Example 2
[0039] Please see Figure 8 , Figure 8This is a schematic diagram illustrating the interaction between the sliding seat and the drive assembly in Embodiment 2. This embodiment is essentially the same as Embodiment 1, except that: there are two sets of drive assemblies 3 symmetrically arranged on both sides of the sliding seat 22. Each drive assembly includes a motor 31 and a gear 33. The gear 33 is mounted on the output shaft of the motor 31, and a rack 225 meshing with the gear 33 is provided on the seat body 221. This structure improves the stability of the sliding seat 22 driven by the motor 31, facilitates control of the sliding stroke of the sliding seat 22 by controlling the number of rotations of the motor 31, reduces the use of sensors, and lowers costs.
[0040] This invention discloses a self-cleaning camera cover that eliminates the need for manual cleaning, saving significant manpower and material costs. Simultaneously, the movement of the lens allows the scraper to clean dirty areas without obstructing the camera lens, ensuring that the camera lens can still capture and inspect external targets through the lens and through-hole during the cleaning process.
