Description

Technical Field

[0001] The utility model relates to the technical field of monitoring equipment, in particular to an infrared camera with a protective cover. Background Art

[0002] With the improvement of people's living standards, security systems will be installed in buildings in residential areas or villa areas. Among them, the integrated face recognition system is mainly used to perform image recognition on people entering and leaving the building. By comparing the collected face images with pre-recorded face images, timely identification of outsiders can be achieved to ensure the personal safety of people in the building.

[0003] Existing infrared cameras are generally exposed to the outside and are easily scratched and stained, resulting in poor image quality. The infrared lamp does not move synchronously with the lens. In the night vision state, the imaging effect will be different at different positions. Therefore, higher-power infrared lamps are generally used. Infrared rays themselves can cause harm to humans, especially for infants and young children, where the harm will be more significant. At the same time, high-intensity infrared light will cause the lens to produce a "halo" phenomenon, reducing the viewing effect. Utility Model Content

[0004] The purpose of the present utility model is to solve the following shortcomings in the prior art: the existing infrared cameras are generally exposed to the outside and are easily scratched and stained, which causes the quality of the captured images to deteriorate; the infrared lamp does not move synchronously with the lens. In the night vision state, the imaging effect at different positions will be different. Therefore, a higher-power infrared lamp is generally used. However, infrared rays themselves can cause harm to people, especially to infants and young children, where the harm will be more significant. At the same time, high-intensity infrared lights can cause the lens to produce a "halo" phenomenon, reducing the viewing effect. Therefore, an infrared camera with a protective cover is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An infrared camera with a protective cover comprises a base and a mounting plate, wherein the mounting plate is fixedly connected to the inner side wall of the base;

[0007] A protection component is provided on the base, and the protection component includes a protective cover, an inner ball head, and a retaining ring. The protective cover is slidably connected to the upper end surface of the base, the inner side wall of the protective cover is fixedly connected to the first motor, the inner ball head is fixedly connected to the output end of the first motor, a through opening is opened on the side wall of the inner ball head, the retaining ring is fixedly connected to the side wall of the through opening, the side wall of the inner ball head is fixedly connected to a lens body, the side wall of the lens body close to one end of the retaining ring is fixedly connected to a light board, the end of the inner ball head close to the retaining ring is fixedly connected to an infrared lens, and both ends of the inner ball head are fixedly connected to decorative pieces.

[0008] Preferably, the protection assembly further comprises an air cylinder and a piston plate, wherein the air cylinder is fixedly connected to the side wall of the mounting plate, and the piston plate is slidably connected to the inner side wall of the air cylinder.

[0009] Preferably, a push rod is fixedly connected to the side wall of the piston plate, the push rod is slidably connected to one side wall of the air cylinder, and one end of the push rod away from the piston plate is fixedly connected to the push plate.

[0010] Preferably, a second motor is fixedly connected to the inner wall of the base, the output end of the second motor is fixedly connected to a rotating shaft, the end of the rotating shaft away from the second motor is fixedly connected to the protective cover, the outer surface of the rotating shaft is fixedly connected to a cam, and the cam is slidably connected to the push plate.

[0011] Preferably, an air inlet pipe is fixedly connected between the air cylinder and the protective cover, an air outlet pipe is fixedly connected to the side wall of the air cylinder, and a one-way valve is provided in each of the air inlet pipe and the air outlet pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. By using the combination of a protective cover and an inner ball head, the lens is protected to prevent the lens from being scratched and causing a deterioration in viewing effect. The inner ball head is driven by a motor to rotate, so that the infrared lamp fixed on the inner ball head rotates synchronously with the lens, thereby improving the efficiency of the infrared lamp and allowing the use of a smaller infrared lamp to reduce harm to the human body.

[0016] 2. While the motor drives the lens to adjust its position, it also drives the cam to continuously push the push plate to move the push rod and the piston plate, thereby continuously extracting the gas in the protective cover and the inner ball head to maintain a vacuum inside, preventing dust from entering and contaminating the lens, and improving the monitoring effect.

[0017] 3. By keeping the inside of the protective cover close to vacuum, dust is reduced and the reflection of infrared light by dust is avoided. The matte black treatment of the retaining ring and the ball head further reduces the infrared light reflected into the lens, avoiding the "halo" phenomenon caused by high-intensity infrared light and improving the viewing effect.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0025] Reference Figures 1-4 An infrared camera with a protective cover includes a base 1 and a mounting plate 2. The mounting plate 2 is fixedly connected to the inner wall of the base 1, and the base 1 is conical.

[0026] A protective assembly is provided on the base 1, and the protective assembly includes a protective cover 3, an inner ball head 5, and a retaining ring 6. The protective cover 3 is slidably connected to the upper end surface of the base 1. The protective cover 3 is composed of two identical hemispherical shells, which are divided into a front shell and a rear shell. In order to ensure the imaging effect, the front shell of the protective cover 3 is made into a high lens surface effect. The first motor 4 is fixedly connected to the inner side wall of the protective cover 3, and the inner ball head 5 is fixedly connected to the output end of the first motor 4. The inner ball head 5 is also composed of two identical front shells and a rear shell. The inner ball head 5 is matte black to reduce the reflection of infrared light. A through hole is opened on the side wall of the inner ball head 5, and the retaining ring 6 is fixedly connected On the side wall of the opening, the lens body 14 is fixedly connected to the side wall of the inner ball head 5, and the retaining ring 6 compensates for the gap between the lens on the lens body 14 and the front shell of the protective cover 3, reducing the infrared light entering the lens and reducing the occurrence of the "halo" phenomenon. A light board 15 is fixedly connected to the side wall of the lens body 14 near the retaining ring 6. When the inner ball head 5 rotates, the relative position of the lens body 14 and the light board 15 remains unchanged. An infrared lens 16 is fixedly connected to the end of the inner ball head 5 near the retaining ring 6, and decorative pieces 20 are respectively fixedly connected at both ends of the inner ball head 5. The decorative piece 20 is divided into two pieces on the left and right, making the lens more beautiful.

[0027] The protection assembly also includes an air cylinder 7 and a piston plate 8. The air cylinder 7 is fixedly connected to the side wall of the mounting plate 2. The piston plate 8 is sealingly and slidingly connected to the inner wall of the air cylinder 7. An air inlet pipe 17 is fixedly connected between the air cylinder 7 and the protective cover 3. An air outlet pipe 18 is fixedly connected to the side wall of the air cylinder 7. A one-way valve is provided in the air inlet pipe 17 and the air outlet pipe 18. The flow direction of the one-way valve in the air inlet pipe 17 is from the protective cover 3 to the air cylinder 7, and the flow direction of the one-way valve in the air outlet pipe 18 is from the air cylinder 7 to the outside world.

[0028] A push rod 9 is fixedly connected to the side wall of the piston plate 8, and the push rod 9 is slidingly connected to one of the side walls of the air cylinder 7. The push rod 9 is slidingly connected to one of the side walls of the air cylinder 7. The push rod 9 and the air cylinder 7 are not sealed. The push rod 9 is fixedly connected to the push plate 10 at one end away from the piston plate 8, and a return spring 19 is fixedly connected between the push plate 10 and the air cylinder 7. A second motor 11 is fixedly connected to the inner wall of the base 1, and a rotating shaft 12 is fixedly connected to the output end of the second motor 11. A rotating groove is provided on the upper end surface of the base 1, and the rotating shaft 12 passes through the rotating groove. The end of the rotating shaft 12 away from the second motor 11 is fixedly connected to the protective cover 3, and a cam 13 is fixedly connected to the outer surface of the rotating shaft 12, which is slidingly connected to the push plate 10.

[0029] When the second motor 11 rotates, the cam 13 is driven to rotate. When the cam 13 approaches the push plate 10, the push plate 10 is squeezed and the return spring 19 is compressed. The push plate 10 drives the piston plate 8 to move toward the mounting plate 2 through the push rod 9. The space between the piston plate 8 and the air cylinder 7 is reduced to form a positive pressure. Under the action of the pressure, the one-way valve in the air inlet pipe 17 is closed, and the one-way valve in the air outlet pipe 18 is opened. The gas in the air cylinder 7 is discharged to the outside along the air outlet pipe 18. When the cam 13 is away from the push plate 10, the squeezing force on the push plate 10 disappears. Under the elastic force of the return spring 19 Under the action, the push plate 10 drives the piston plate 8 to reset through the push rod 9, and the space between the piston plate 8 and the air cylinder 7 increases and forms a negative pressure. Under the action of pressure, the one-way valve in the air inlet pipe 17 opens, and the one-way valve in the air outlet pipe 18 closes. The gas in the protective cover 3 enters the air cylinder 7 along the air inlet pipe 17. When the lens body 14 is continuously rotated to adjust the viewing angle, the gas in the protective cover 3 is also continuously pumped to the outside. When the protective cover 3 is close to a vacuum, the piston plate 8 is sucked under negative pressure, and the reset spring 19 no longer rebounds until the gas slowly leaks into the protective cover 3. While adjusting the viewing angle, the gas is continuously pumped out to keep the vacuum in the protective cover 3, preventing dust from entering and contaminating the lens, thereby improving the monitoring effect.

[0030] When vertical adjustment is required, it is only necessary to start the first motor 4. The rotation of the first motor 4 drives the inner ball head 5 to rotate, and the light board 15 rotates together with the lens body 14, thereby avoiding differences in imaging effects. A lower-power infrared lamp can be selected, reducing harm to infants and young children. At the same time, reducing the power of the infrared lamp also reduces the intensity of the infrared rays entering the lens. The matte-finished inner ball head 5 has a strong absorption capacity for infrared rays, which reduces the reflection of infrared rays. The protective cover 3 is evacuated to a near vacuum, which also reduces dust and the dust's ability to reflect infrared rays, greatly reducing the intensity of infrared rays entering the lens, reducing the "halo" phenomenon, and improving the viewing effect of the lens.

[0031] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
