Description
Technical Field
[0001] This application relates to the field of camera technology, and in particular to a dustproof structure for cameras. Background Technology
[0002] Existing outdoor surveillance cameras are typically designed with high waterproof ratings, capable of withstanding rain and functioning normally even in stormy weather. Although some cameras are designed to prevent dust ingress and withstand water impact, dust or impurities can still accumulate on the lens of the camera body over time, affecting the clarity of the captured images.
[0003] Existing technologies also include methods or structures for cleaning cameras to ensure that the images captured by the camera maintain sufficient clarity. For example, a self-cleaning structure can be used to clean the lens of the camera body.

However, the airflow cannot stably and effectively clean the dust or impurities attached to the lens surface, resulting in poor cleaning results.
[0004] Therefore, this application proposes a dustproof structure for a camera to solve the above problems. Utility Model Content

[0020] This application provides a dustproof structure for a camera, comprising: a mounting bracket and a camera body; the camera body is disposed on a connecting component below the mounting bracket and is controlled to rotate by a first motor on the connecting component; a cleaning component adapted to the lens of the camera body is disposed inside the mounting bracket, and the cleaning component is controlled by a second motor inside the mounting bracket; the first motor is used to control the rotation of the camera body so that the lens of the camera body contacts the cleaning component, and the second motor is used to control the cleaning component to rub against the lens of the camera body;

[0029] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0030] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0031] Existing technologies also include methods or structures for cleaning cameras to ensure that the images captured by the camera maintain sufficient clarity. For example, a self-cleaning structure can be used to clean the lens of the camera body. This self-cleaning structure mainly involves setting multiple dust-blowing structures on the camera housing to blow away dust or impurities from the lens surface. However, the airflow cannot stably and effectively clean the dust or impurities attached to the lens surface, resulting in poor cleaning results.
[0032] Multiple dust-blowing mechanisms are incorporated into the camera housing. An air pump inside the housing provides airflow to these mechanisms, causing them to periodically blow air onto the camera body. This dislodges dust adhering to the camera's surface, keeping the lens clean and eliminating the need for manual cleaning. However, some dust may adhere to the lens, and if the airflow is not stable and effective, it may result in poor cleaning.
[0033] Therefore, this application proposes a dustproof structure for a camera to solve the above problems.
[0034] The following describes in detail, with reference to the accompanying drawings and specific embodiments, the implementation of a camera dustproof structure proposed in this application.
[0035] Figure 1 The left view of a camera dustproof structure provided in this application embodiment Figure 1 . Figure 2 This is a front view of a camera dustproof structure provided in an embodiment of this application. Figure 1 and Figure 2 As shown, the dustproof structure of the camera includes: a mounting bracket 1 and a camera body 2;
[0036] The camera body 2 is mounted on the connecting component 3 below the mounting frame 1, and its rotation is controlled by the first motor 4 on the connecting component 3; the mounting frame 1 is provided with a cleaning component 5 that is adapted to the lens of the camera body 2, and the cleaning component 5 is controlled by the second motor 6 inside the mounting frame 1.
[0037] During cleaning, the first motor 4 is used to control the rotation of the camera body 2 so that the lens of the camera body 2 contacts the cleaning component 5, and the second motor 6 is used to control the cleaning component 5 to rub the lens of the camera body 2.
[0038] A water collection tank 7 is provided above the mounting frame 1, and a water pump 8 is provided inside the water collection tank 7; the water outlet of the water pump 8 extends into the interior of the mounting frame 1, and a nozzle 9 is provided at the water outlet.
[0039] During cleaning, the water collection tank 7, the water pump 8, and the nozzle 9 work together to spray water onto the lens of the camera body 2.
[0040] Mounting bracket 1 can be a shell structure with internal storage space. Such a shell structure can provide a fixed and stable installation environment for the internal components, preventing external environmental factors such as dust and rain from affecting the internal components and playing a protective role. Moreover, compared with a solid structure, the shell structure can make the mounting bracket 1 lighter while ensuring structural strength, which can save production materials and is also easy to carry and install.
[0041] The camera body 2 can be positioned below the mounting bracket 1, allowing the mounting bracket 1 to provide some degree of shielding over the camera body 2. This protects the camera body 2 by reducing the accumulation of debris and excessive rainwater runoff, thus reducing the risk of wear and damage caused by debris and rainwater, potentially extending its lifespan. If the mounting bracket 1 is damaged by debris and excessive rainwater runoff before the camera body 2, the mounting bracket 1 and its related structures can be replaced. Replacing the mounting bracket 1 and its related structures is less costly than replacing the camera body 2.
[0042] The camera body 2 is connected to the mounting frame 1 below the mounting frame 1 via a connecting component 3, and the connection point between the connecting component 3 and the camera body 2 is also located below the mounting frame 1; a first motor 4 is provided at the connection point between the camera body 2 and the connecting component 3.
[0043] The mounting bracket 1 contains a cleaning component 5, which is protected by the mounting bracket 1 as a component inside the mounting bracket 1. At the same time, the cleaning component 5, as a component inside the mounting bracket 1, is also located above the camera body 2.
[0044] When the camera body 2 is in storage, it can generally be in a horizontal and parallel state with the mounting bracket 1; however, cameras used for monitoring are generally set up at a high position to monitor the environment at a lower level; when the camera body 2 is monitoring, the mounting bracket 1 may be in a horizontal state; the camera body 2 is divided into two ends, one end is the lens and the other end is the tail; the tail of the camera body 2 may be relatively close to the mounting bracket 1, and the lens of the camera body 2 may be relatively far away from the mounting bracket 1 and in an inclined state;
[0045] The camera body 2 is located below the mounting bracket 1, and the lens of the camera body 2 is also located below the mounting bracket 1. The lens of the camera body 2 needs to be cleaned and needs to be close to the cleaning component 5. Therefore, when the lens needs to be cleaned, the first motor 4 controls the camera body 2 to rotate so that the tail of the camera body 2 moves away from the mounting bracket 1, so that the lens of the camera body 2 moves closer to the mounting bracket 1, and so that the lens of the camera body 2 gradually moves closer to and contacts the cleaning component 5.
[0046] Simply contacting the cleaning component 5 is insufficient for effective cleaning; adequate friction is also required. The cleaning component 5 is controlled by a second motor 6 installed inside the mounting bracket 1, causing friction between the cleaning component 5 and the lens of the camera body 2 to achieve sufficient cleaning force and a good cleaning effect. The cleaning component 5 can be fixedly connected to the second motor 6. Over time, the lens may become dirty due to dust, rain, or other contaminants, affecting the camera's imaging performance. The automated cleaning component can clean the lens periodically or as needed, reducing the need for manual maintenance.
[0047] The second motor 6 drives the cleaning component 5 to clean the lens of the camera body 2, which can effectively improve the cleaning effect on the lens of the camera body 2. Moreover, the structure is simple and can operate stably for a long time.
[0048] Dry brushing of the lens of the camera body 2 using the cleaning component 5 also has a good cleaning effect, but wet brushing is still better than wet brushing. Wet brushing can also increase the lubrication and smoothness of friction between the cleaning component 5 and the lens of the camera body 2, which can also reduce damage to the lens of the camera body 2. Therefore, when the cleaning component 5 cleans the lens of the camera body 2, water can also be sprayed onto the lens of the camera body 2.
[0049] The structure related to water spraying includes a water collection tank 7, a water pump 8, and a nozzle 9. The water collection tank 7 is located above the mounting bracket 1, and the water pump 8 is located inside the water collection tank 7. The water outlet of the water pump 8 extends into the mounting bracket 1, and a nozzle 9 is provided at the water outlet. The nozzle 9 is located at a position where water can be sprayed onto the lens when cleaning the lens. The water collection tank 7 is used to provide a water source. The water pump 8 can be located at the bottom inside the water tank 7 to effectively utilize the water in the water collection tank 7 and spray the water out through the nozzle 9, allowing the cleaning component 5 and water to clean the lens of the camera body 2 simultaneously, thereby achieving a better cleaning effect. As its name suggests, the water collection tank 7 has a water collection function to provide a sufficient water source without relying on an external water source, enhancing the independence and reliability of the structure related to water spraying.
[0050] The camera body 2 is positioned below the mounting bracket 1, allowing the mounting bracket 1 to partially block dust above the camera. The mounting bracket 1 and the camera are connected by a connecting component 3 located below the mounting bracket 1. The connecting component 3 is equipped with a first motor 4, which controls the rotation of the camera body 2 so that the lens of the camera body 2 can contact the cleaning component 5. The mounting bracket 1 contains the cleaning component 5, which is controlled by a second motor 6 to clean the lens of the camera body 2. This flexible structure ensures effective cleaning of the lens.
[0051] To improve the cleaning effect, water is collected in the water collection tank 7, pumped from the water collection tank 7 by the water pump 8, and sprayed onto the lens through the nozzle 9 at the outlet of the water pump 8. The combination of cleaning component 5 and water can enhance the cleaning power. The water collection tank 7 can enhance the independence and reliability of the cleaning structure. The above structure for cleaning the lens of the camera body 2 does not require manual intervention and can be automated, which can improve cleaning efficiency and reduce maintenance costs.
[0052] The water collection tank 7, which has a water collection function, collects water through a related structure:
[0053] For example, the top of the water collection tank 7 is provided with an opening for collecting rainwater.
[0054] Since surveillance cameras are generally exposed to the natural environment, the water collection tank 7 will also be subject to rainwater erosion. In order to effectively utilize natural rainwater resources, an opening is provided on the top of the water collection tank 7 to facilitate the collection and utilization of rainwater resources. The opening of the water collection tank 7 can be set as a strip opening, a hole opening, or other shapes. If the top of the water collection tank 7 has a certain thickness, the opening of the water collection tank 7 can also be set such that the outer opening of the top of the water collection tank 7 is larger than the inner opening of the top of the water collection tank 7, so as to better collect rainwater.
[0055] When the opening of the water collection tank 7 is set to a small hole shape, it can effectively prevent impurities from entering the water collection tank 7. In addition, better blocking can be set:
[0056] For example, a filter screen 10 is provided at the opening at the top of the water collection tank 7, and the filter screen 10 is arranged at an angle.
[0057] The filter screen 10 is generally a fine mesh structure, which has good flowability and good impurity blocking effect. Therefore, the filter screen 10 can be installed at the inner or outer position of the top of the water collection tank 7. The filter screen 10 can be designed to be detachable to facilitate cleaning or replacement of the filter screen 10 with poor filtration effect or damage. Alternatively, the top of the water collection tank 7 has a sandwich structure, and the filter screen 10 can be installed between the sandwich layers.
[0058] To achieve better filtration, the top of the water collection tank 7 is tilted, and the filter screen 10, which is attached to the top of the water collection tank 7, is also tilted. By setting the filter screen 10, external impurities can be prevented from entering the water collection tank 7. At the same time, setting the filter screen 10 at a tilt can prevent external impurities from being trapped on the filter screen 10 and affecting the collection of rainwater. In other words, the tilted design of the filter screen 10 can effectively extend the effective function of the filter screen 10 and minimize the need for cleaning or replacement of the filter screen 10.
[0059] The lens of the camera body 2 needs to be rotated to the position of contact cleaning component 5 for cleaning. The specific position of the lens of the camera body 2 is determined by the sensing module, which includes an infrared sensor 11 and an infrared sensing block 12.
[0060] For example, an infrared sensing block 12 is provided on one side of the camera body 2, and an infrared sensor 11 is provided on one side of the mounting bracket 1.
[0061] When the infrared sensor 11 detects the infrared sensor block 12, it indicates that the camera body 2 has rotated to the correct position and the camera body 2 stops rotating; after the camera body 2 has rotated to the correct position, the second motor 6 is started.
[0062] The infrared sensor 11 is located on one side inside the mounting bracket 1. Therefore, as a component inside the mounting bracket 1, the infrared sensor 11 is protected by the mounting bracket 1. As a component inside the mounting bracket 1, the infrared sensor 11 is also located above the camera body 2.
[0063] Infrared sensor block 12 is located on one side of the camera body 2. Infrared sensor block 12 is opposite to infrared sensor 11. In a suitable position, infrared sensor block 12 can be detected by infrared sensor 11. The camera body 2 is rotated by the first motor 4. As the lens of the camera body 2 gradually approaches the cleaning component 5, infrared sensor block 12 moves with the camera body 2 to a position that can be detected by infrared sensor 11. It is detected by infrared sensor 11 when there is no obstruction.
[0064] When the infrared sensor 11 detects the infrared sensing block 12, it indicates that the camera body 2 has rotated to the correct position. At this time, the second motor 6 is started. This can prevent the cleaning component 5 from obstructing the rotation of the camera body 2 if the camera body 2 has not rotated to the correct position, thus avoiding any impact on the camera body 2.
[0065] Mounting bracket 1 can itself cover the camera body 2:
[0066] For example, the horizontal length of the mounting bracket 1 is greater than the horizontal length of the camera body 2, which is used to form a shield above the camera body 2.
[0067] The camera body 2 is positioned below the mounting bracket 1. The mounting bracket 1 forms a certain degree of obstruction above the camera body 2. Making the horizontal length of the mounting bracket 1 greater than the horizontal length of the camera body 2 can increase the obstruction area. Making the horizontal width of the mounting bracket 1 greater than the horizontal width of the camera body 2 can also increase the obstruction area.
[0068] Cleaning component 5 is designed according to the lens shape:
[0069] For example, the surface of the cleaning component 5 is completely in contact with the lens surface of the camera body 2, and the cleaning component 5 completely covers the lens of the camera body 2 when rubbed.
[0070] The lens surface of the camera body 2 is generally a spherical curved surface, so the cleaning component 5 can be set as a strip structure with a certain width, and the long side of the strip structure of the cleaning component 5 is completely attached to the lens surface to facilitate cleaning. During cleaning, the central axis of the lens surface of the camera body 2 can be directly aligned with the rotating shaft of the second motor 6 corresponding to the cleaning component 5. The long side of the strip structure of the cleaning component 5 exceeds the curvature radius of the lens surface, and the cleaning component 5 can completely cover the lens of the camera body 2 during rotation.
[0071] The cleaning component 5, which has a strip-shaped structure, is fixed on the rotating shaft of the second motor 6. The two sides of the rotating shaft are of unequal length. The longer side covers the radius of curvature of the lens surface, and the shorter side will not prevent the camera body 2 from hitting the cleaning component 5 when it is lifted.
[0072] For example, the cleaning component 5 is a nylon brush.
[0073] The cleaning component 5 can be a cleaning brush; to ensure the cleaning effect, the cleaning brush is made of nylon bristles. By setting the cleaning brush to be made of nylon bristles, the cleaning brush has the advantages of being soft and elastic, thus avoiding scratching the lens of the camera body 2.
[0074] Spray nozzle 9 is set to spray water onto the lens:
[0075] For example, the nozzle 9 is positioned close to the cleaning component 5.
[0076] The nozzle 9 is positioned close to the cleaning component 5, and can spray water onto the lens during cleaning to increase the cleaning power.
[0077] Specific details of the housing structure of mounting bracket 1:
[0078] For example, the mounting bracket 1 has openings at the bottom and top, and the opening at the bottom of the mounting bracket 1 is only large enough for the camera body 2 to be inserted, and the opening at the top of the mounting bracket 1 is only large enough for the water outlet of the water pump 8 to pass through; the mounting bracket 1 is closed on all four sides.
[0079] A water collection tank 7 is installed on the top of the mounting frame 1. The outlet of the water pump 8 in the water collection tank 7 extends into the interior of the mounting frame 1. The entire outlet can be a pipe of a certain length and the outlet of the pipe is equipped with a nozzle 9. Therefore, the top of the mounting frame 1 has only one hole for the pipe to pass through, and this hole can be sealed to the outer diameter of the pipe. Similarly, the bottom of the water collection tank 7 has a hole for the pipe to pass through, and the sealed connection prevents water leakage.
[0080] The mounting bracket 1 has a closed surface on all four sides, which serves to shield and protect the internal components of the mounting bracket 1; the bottom of the mounting bracket 1 has an opening for the camera body 2 to be inserted; the opening at the bottom of the mounting bracket 1 can be slightly larger than the position occupied by the camera body 2 during insertion, or the bottom of the mounting bracket 1 can be a completely hollow structure to prevent water accumulation inside the mounting bracket 1.
[0081] The dustproof structure of this camera ensures sufficient monitoring range while being cleaned.
[0082] For example, the connecting component 3 extends into the mounting bracket 1 and is controlled to rotate by a third motor 13 inside the mounting bracket 1; the third motor 13 is used to control the connecting component 3 to drive the camera body 2 to rotate laterally, and the first motor 4 is used to control the camera body 2 to rotate longitudinally.
[0083] The first motor 4 controls the vertical rotation of the camera body 2; the connecting component 3 extends into the mounting bracket 1 and is fixed to the third motor 13 inside the mounting bracket 1; the third motor 13 controls the rotation of the connecting component 3, which in turn drives the camera body 2 to rotate horizontally; the camera body 2 can rotate flexibly in both horizontal and vertical directions, thereby expanding the monitoring range and improving the flexibility and practicality of the camera. This is especially important for scenarios requiring large-scale monitoring.
[0084] Figure 3 The left view of a camera dustproof structure provided in this application embodiment Figure 2 .like Figure 3 As shown, the camera body 2 rotates to the position of the cleaning component 5 and fits into the cleaning component 5;
[0085] The preferred embodiment of the camera dustproof structure is as follows:
[0086] The lower part of the mounting bracket 1 is equipped with a rotatable rotating bracket (connecting part 3), the camera body 2 is mounted on the rotating bracket, and a first motor 4 that can control the rotation of the camera body 2 is mounted on one side of the rotating bracket.
[0087] The mounting bracket 1 houses a second motor 6. The power output end of the second motor 6 is equipped with a cleaning brush (cleaning component 5) that is compatible with the lens of the camera body 2. By setting the first motor 4 to rotate the camera body 2 to the position to be cleaned, the lens of the camera body 2 comes into contact with the cleaning brush. The second motor 6 drives the cleaning brush to rotate and clean the lens of the camera body 2, which can effectively improve the cleaning effect on the lens of the camera body 2. At the same time, the structure is simple and can operate stably for a long time.
[0088] A third motor 13 is installed at the lower part of the mounting bracket 1. The power output end of the third motor 13 is connected to the rotating bracket. The third motor 13 drives the camera body 2 to rotate and adjust the horizontal shooting angle through the rotating bracket. The first motor 4 drives the camera body 2 to rotate and adjust the vertical shooting angle.
[0089] The third motor 13 drives the camera body 2 to rotate via the rotating frame to adjust the horizontal shooting angle, while the first motor 4 drives the camera body 2 to rotate to adjust the vertical shooting angle, which can effectively expand the shooting angle of the camera body 2.
[0090] A water collection tank 7 is installed on the upper part of the mounting frame 1. The upper part of the water collection tank 7 is open. A water pump 8 is installed at the bottom of the water collection tank 7. The water outlet of the water pump 8 extends into the mounting frame and is equipped with a nozzle 9 corresponding to the cleaning brush. By setting the water pump 8 and the nozzle 9 to work together, water can be sprayed onto the cleaning brush, thereby improving the cleaning effect of the cleaning brush on the lens of the camera body 2. At the same time, the water collection tank 7 is open to collect and utilize rainwater.
[0091] A filter screen 10 is installed at the opening of the water collection tank 7, and the filter screen 10 is set at an angle. By setting the filter screen 10, external impurities can be prevented from entering the water collection tank 7. At the same time, setting the filter screen 10 at an angle can prevent external impurities from being stuck on the filter screen 10 and affecting the collection of rainwater by the filter screen 10.
[0092] An infrared sensor block 12 is installed on one side of the camera body 2, and an infrared sensor 11 corresponding to the infrared sensor block 12 is installed on one side of the mounting bracket. The infrared sensor 11 determines whether the camera body 2 has rotated into position by detecting the position of the infrared sensor block 12.
[0093] By setting the infrared sensor 11, the position of the infrared sensing block 12 on the camera body 2 can be detected to determine whether the camera body 2 has rotated into place. This avoids the second motor 6 driving the cleaning brush to rotate and causing damage to the lens of the camera body 2 if it does not rotate into place, thus effectively protecting the camera body 2 and making the equipment operate more stably.
[0094] The cleaning brush is made of nylon bristles, which gives it the advantages of being soft and elastic, thus preventing the cleaning brush from scratching the camera body and lens.
