Description

Technical Field

[0001] The present application relates to the technical field of cameras, and in particular to an anti-fogging outdoor camera. Background Art

[0002] The structure of an outdoor camera generally includes a body, camera, microphone, battery, motherboard, bracket, etc. At present, outdoor cameras need to have good waterproof performance, flexible installation methods, and be able to be installed in different ways such as front mounting, hanging mounting or side mounting. When working in a high temperature environment, heat dissipation needs to be considered.

[0003] Common outdoor cameras on the market generally have the problem of lens fogging, which causes image abnormalities for a short period of time. A camera that does not fog at all needs to have a very good waterproof rating or use an integrated waterproof lens, but both methods have high manufacturing costs.

[0004] To this end, the present application provides an anti-fogging outdoor camera. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the present application provides an anti-fogging outdoor camera, which constructs an independent and closed space by cleverly arranging a waterproof silicone ring between the lens and the lens as a pressing structure, thereby effectively blocking the entry of air into the device cavity, and solving the technical problem that the outdoor camera lens is prone to fogging under specific environmental conditions (such as high humidity and large temperature difference), resulting in image abnormalities in a short period of time.

[0006] The technical solution adopted by this application to solve its technical problem is:

[0007] An anti-fogging outdoor camera comprises a front shell and a rear shell snapped together;

[0008] The front shell is provided with a plurality of lenses and mirrors, the outer periphery of the lens is provided with a groove, and a pressing structure is provided in the groove;

[0009] The lens covers a plurality of lenses and a pressed structure, and a cavity is formed between the lens, the plurality of lenses and the pressed structure.

[0010] As a preferred solution, the pressing structure includes a waterproof pressing structure.

[0011] As a preferred solution, the pressing structure is attached to the inner wall of the groove and the outer wall of the lens, and the height of the pressing structure is not higher than the outer edge of the groove.

[0012] As a preferred solution, the pressing structure includes a silicone ring.

[0013] As a preferred solution, the lens group includes a non-waterproof lens.

[0014] As a preferred solution, the lens is a waterproof lens.

[0015] As a preferred solution, a working indicator light, a charging indicator light and a microphone are provided on the front shell.

[0016] As a preferred solution, the rear shell is arranged on a rotating assembly, and the rotating assembly is arranged on a bracket.

[0017] As a preferred solution, a PIR sensor is arranged on the lower part of the rear shell.

[0018] As a preferred solution, a photosensor is arranged above the lens.

[0019] The beneficial effects of this application are:

[0020] 1. The outdoor camera described in this application has a waterproof silicone ring as a pressing structure in the groove of the lens. The front end of the silicone ring is tightly pressed against the inner surface of the lens to ensure sealing. The silicone ring can maintain the sealing effect for a long time due to its excellent waterproofness, elasticity and aging resistance, and is not affected by the external environment. Moreover, the lens is a waterproof lens, which not only covers the lens and the pressing structure, but also forms a cavity between them. The cavity is independent and isolated from the air inside the device cavity, thereby avoiding the entry and condensation of water vapor.

[0021] 2. The outdoor camera described in the present application is composed of a front shell and a rear shell that are snapped together. This structure is convenient for assembly and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will clearly and completely describe the concept, specific structure and technical effects of the present application in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of them. Based on the embodiments of the present application, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present application. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features created in this application can be combined interactively without conflicting with each other.

[0029] The reasons for lens fogging are: high air humidity and large temperature difference between the inside and outside of the device. In order to solve the problem of abnormal images in a short period of time caused by lens fogging, a completely fog-free camera needs to have a good waterproof rating or use an integrated waterproof lens, but both methods have a high manufacturing cost. Figure 1-4 The anti-fogging outdoor camera shown comprises a front shell 1 and a rear shell 2 which are snap-connected together;

[0030] The front shell 1 is provided with a plurality of lenses 3 and lenses 4, the outer periphery of the lens 3 is provided with a groove 5, and a pressing structure 6 is provided in the groove 5;

[0031] The lens 4 covers the plurality of lenses 3 and the pressed structure 6 , and a cavity is formed between the lens 4 , the plurality of lenses 3 and the pressed structure 6 .

[0032] Specifically, the front shell and the rear shell are tightly connected by a snap-fitting method to form the main structure of the camera. This snap-fitting design not only simplifies the assembly process and improves production efficiency, but also ensures the sealing and stability of the camera housing.

[0033] Specifically, the lens is mounted on the front shell, and the lens covers the lens and the periphery of the pressed structure to form a closed cavity. This design forms a relatively independent and sealed environment between the lens and the lens.

[0034] Because the main reason for lens fogging is the condensation of water vapor caused by the large difference in air humidity and temperature inside and outside the device, by placing the lens in a space isolated from the air inside the device (inside the cavity), even if the external environment has high humidity and a large temperature difference, the lens surface will not directly contact the water vapor that may condense, thereby avoiding the occurrence of fogging; the above technical solution only needs to add a pressing structure around the lens to achieve a waterproof and anti-fog effect, and the assembly process is simple and quick; at the same time, because the pressing structure is installed inside the device, it is not easily affected by the external environment, and therefore has better anti-aging performance.

[0035] More specifically, the cavity is designed to be cylindrical, with a diameter slightly larger than the groove diameter and a height of 2mm to ensure that there is enough space around the lens to avoid condensation. In addition, dry nitrogen can be filled into the cavity to reduce relative humidity, and tiny air holes are set at the edge of the lens. These air holes are covered with a waterproof and breathable membrane to prevent external moisture from entering, while allowing internal gas to exchange with the outside world to maintain the air pressure balance in the cavity.

[0036] like Figure 4 As shown, in one embodiment, the pressing structure 6 comprises a waterproof pressing structure 6.

[0037] Specifically, a groove is provided around the outside of the lens, and a press-fit structure is installed in the groove. The press-fit structure fits tightly on the inner wall of the groove and the outer wall of the lens, ensuring the stability and sealing of the structure. The waterproof press-fit structure (such as a silicone ring) is a key component of waterproof sealing. By fitting tightly on the groove and the outer wall of the lens, it effectively prevents the infiltration of moisture and dust, thereby improving the waterproof performance of the camera.

[0038] In one embodiment, the pressing structure 6 is attached to the inner wall of the groove 5 and the outer wall of the lens 3 , and the height of the pressing structure 6 is not higher than the outer edge of the groove 5 .

[0039] Therefore, the pressed structure also plays the role of fixing the position of the lens, preventing the lens from loosening or shifting during long-term use, and ensuring the stability and accuracy of shooting.

[0040] In one embodiment, the compression structure 6 includes a silicone ring.

[0041] In the present application, the silicone ring not only has a waterproof function, but also silicone is made of soft material and has a certain buffering and shock-absorbing effect, which can absorb part of the external impact and vibration and protect the lens from damage.

[0042] More specifically, the silicone ring has a circular cross-section with an outer diameter of 5mm, an inner diameter of 3mm, and a thickness of 1mm, ensuring that it can fit tightly in the lens groove while maintaining sufficient elasticity to absorb external impact. The Shore hardness of the silicone ring is 60A, which is both hard enough to maintain a stable shape and flexible enough to adapt to expansion and contraction at different temperatures. When installing, first place the silicone ring in the lens groove, then gently press the lens in so that the silicone ring fits tightly against the lens and the inner wall of the groove.

[0043] In one embodiment, the lens group 3 includes a non-waterproof lens 3. In the present application, from the perspective of cost, a non-waterproof lens is usually cheaper than a waterproof lens, and the use of a non-waterproof lens can reduce the overall cost. In addition, a non-waterproof lens may have higher flexibility in design and manufacturing, allowing designers to adjust the lens structure according to specific needs to achieve the best optical effect or meet specific space layout requirements.

[0044] In one embodiment, the lens 4 is a waterproof lens 4 .

[0045] In this application, the main function of waterproof lenses is to prevent water, moisture or other liquids from entering the interior of the lens, thereby protecting the delicate optical components and electronic components inside the lens from damage. At the same time, in a humid or rainy environment, waterproof lenses can extend the service life of the lens and reduce performance degradation or malfunctions caused by moisture.

[0046] In addition, waterproof lenses are indispensable in certain specific application scenarios, such as outdoor photography, underwater photography, etc. These scenarios have strict requirements on the waterproof performance of the lens, and only lenses with waterproof function can meet the requirements.

[0047] In one embodiment, a working indicator light 7 , a charging indicator light 8 and a microphone 9 are provided on the front shell 1 .

[0048] Specifically, the working indicator light is installed on the front shell, and the specific position may be adjusted according to design requirements, so that users can observe and identify the working status of the camera. The working indicator light flashes or stays on in different colors to indicate the current working status of the camera to the user, such as power on, recording, charging, etc., which improves the convenience and intuitiveness of use.

[0049] The charging indicator light is usually located on the front shell of the device. The specific location may be adjusted according to design requirements, but it is generally selected in a location that is easy for users to observe. In terms of electrical connection, the charging indicator light is connected to the power management module through the wires on the circuit board. When the device is in charging state, the power management module will control the indicator light to light up to indicate the charging status.

[0050] The microphone is usually installed on the front shell of the device, close to the lens, to ensure that the surrounding sound can be clearly captured. In terms of electrical connection, the microphone is connected to the audio processing module inside the device through an audio cable, which converts the collected sound signals into electrical signals for processing and transmission.

[0051] In one embodiment, the rear housing 2 is disposed on a rotating assembly 10 , and the rotating assembly 10 is disposed on a bracket 11 .

[0052] Specifically, the rotation assembly is a key component connecting the camera body and the bracket, which allows the camera to rotate horizontally and / or vertically within a certain range. The rotation assembly can be selected from common rotation assemblies according to actual needs. For example, the rotation assembly includes a horizontal rotation axis and a vertical rotation axis, both of which are connected to the bracket through bearings to ensure that the camera can rotate freely in the horizontal and vertical directions. The horizontal rotation range is 360 degrees, and the vertical rotation range is -90 degrees to +90 degrees.

[0053] The bracket is responsible for fixing the camera to a specific location, such as a wall, ceiling, etc. In terms of connection, the rotating assembly is fixed to the bracket by fasteners (such as screws), and the camera body is connected to the rotating assembly by a connector (such as a bearing or a buckle).

[0054] In one embodiment, a PIR sensor 12 is disposed on the lower portion of the rear housing 2 .

[0055] Specifically, the PIR sensor is usually installed at the bottom or side of the rear shell of the camera to detect changes in infrared radiation in the surrounding environment. In terms of electrical connection, the PIR sensor is connected to the microprocessor inside the device through a signal line, and the detected infrared signal is converted into an electrical signal for processing and analysis. For example, a PIR sensor model XYZ-123 is used.

[0056] In one embodiment, a photosensor 13 is disposed above the lens 3 .

[0057] Specifically, the photosensor is usually installed above or near the lens to accurately sense the light intensity of the surrounding environment. In terms of electrical connection, the photosensor is connected to the image processing module inside the device through a signal line, and the detected light intensity information is converted into an electrical signal for processing and adjustment. For example, a photosensor model ABC-456 is used.

[0058] like Figure 3 As shown, the specific assembly process of the outdoor camera described in this application is as follows:

[0059] Prepare all parts, including the front shell, back shell, lens, lens, silicone ring, rotating assembly and bracket, etc.

[0060] Place the silicone ring into the lens groove, making sure it is positioned correctly and fits snugly.

[0061] Gently press the lens onto the lens so that it covers the lens and the groove and the edge of the lens fits snugly against the front shell.

[0062] Align the front and back covers and secure with snap-fit.

[0063] Install the rotating assembly on the bracket, and then fix the rear shell on the rotating assembly.

[0064] Connect all electrical components, including PIR sensor, light sensor, working indicator light, charging indicator light, microphone, etc.

[0065] Carry out final debugging and testing to ensure that all functions of the camera are normal.
