Description

Technical Field

[0001] The present invention belongs to the technical field of camera devices, and particularly relates to a camera that can prevent damage in a strong earthquake environment. Background Art

[0002] A camera converts optical image signals into electrical signals for storage or transmission. When we photograph an object, the light reflected from the object is collected by the camera lens and focused on the light-receiving surface of the imaging device. Then, the light is converted into electrical energy by the imaging device to obtain a video signal. The optoelectronic signal is very weak and needs to be amplified by a preamplifier circuit, and then processed and adjusted by various circuits. Finally, the obtained standard signal can be sent to a recording medium such as a video recorder for recording, or transmitted through a transmission system or displayed on a monitor.

[0003] In a Chinese patent with the authorization announcement number CN112422800B, a camera with dust and shock prevention functions is disclosed, including an explosion-proof housing, an inner housing, a camera, a mounting bracket, and a signal transfer box. A first partition is horizontally installed inside the explosion-proof housing, a first motor is installed in the middle of the bottom of the explosion-proof housing, a microprocessor is provided on the left side of the backup power supply, a second motor is installed inside the inner housing, a connecting rod is provided at the bottom left of the mounting bracket, a second partition is provided inside the signal transfer box, a signal transmission module is provided above the second partition, and a storage battery is provided at the bottom of the signal transfer box. This camera with dust and shock prevention functions is provided with a first shock-absorbing spring and a second shock-absorbing spring. The first shock-absorbing spring is located between the explosion-proof housing and [not clear in the original], and the second shock-absorbing spring is located between the explosion-proof housing and the shock-absorbing disc. When the explosion-proof housing or the mounting bracket is impacted, the first shock-absorbing spring and the second shock-absorbing spring slow down the impact to protect the precision parts inside the device.

[0004] Although the above technical solution can shock-absorb the camera and prevent damage to precision parts, however, in a strong earthquake environment, there will inevitably be some falling objects above the camera. When the falling object hits the camera, the strong impact force is likely to cause damage to the camera lens or the camera housing. Therefore, the above technical solution can only shock-absorb the camera and prevent damage to the precision parts inside the device camera, but cannot protect the camera from external bumps.

The device can effectively protect the camera and prevent the camera from being damaged by falling objects.

[0021] 2. This camera is designed to prevent damage in a strong earthquake environment. When encountering a micro-earthquake, the vibration sensor senses that the vibration is not strong, and the vacuum device is activated to evacuate the air inside the airbag. When the air inside the airbag is evacuated, the airbag will shrink and stick to the camera component, increasing the friction between the airbag and the camera, thereby reducing the shaking of the camera caused by vibration. At the same time, the airbag is made of transparent material, so that the airbag will not affect the normal shooting of the camera. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figure 1-2 , the present invention provides the following technical solutions: A camera that is damage-proof in a strong earthquake environment, including: a base 1, and a camera assembly 2 disposed on the base 1. The base 1 can be installed on a wall surface, and the camera assembly 2 is disposed on the base 1, so that the camera assembly 2 can be installed on the wall surface through the base 1; a vibration sensor 13, disposed on the base 1, the vibration sensor 13 can be purchased on the market and is installed on the base 1 for sensing the vibration on the base 1; a protection component 3, disposed on the base 1, the protection component 3 is foldable and can be folded on one side of the base 1. When encountering a strong earthquake, the protection component 3 expands around the camera assembly 2 to protect the camera assembly 2.

[0036] In a specific embodiment of the present invention, when the vibration sensor 13 senses vibration, the protection component 3 operates to expand the protection component 3 and cover the camera assembly 2 inside the protection component 3, so as to avoid damage to the camera caused by an object falling above the camera due to vibration. At the same time, when the vibration sensor 13 does not sense vibration, the protection component 3 is folded on one side of the camera assembly 2, enabling the camera to be used normally. This device can effectively protect the camera and avoid the collision damage of falling objects to the camera.

[0037] Specifically, please refer to Figure 4 、 Figure 7 、and Figure 9, the protective component 3 includes a fixed section 31 fixed on the base 1 and a movable section 32 that can overlap with the fixed section 31 by rotation. The fixed section 31 is fixed on the base 1, and the movable section 3 moves on the base 1. The cross-sections of both the fixed section 31 and the movable section 32 are arc-shaped and both ends are arranged on the base 1. The rotation axes of multiple movable sections 3 are coaxial. The movable section 32 rotates relatively at the connection between the fixed section 31 and the base 1. A first driving device 33 for driving the movable section 32 at the end far from the fixed section 31 to rotate is arranged on the base 1. The first driving device 33 is a motor. A limiting groove 34 is formed on each movable section 32, and a limiting block 35 adapted to the limiting groove 34 on the adjacent movable section 32 is arranged on the movable section 32 and the fixed section 31. By the operation of the first driving device 33, one of the movable sections 3 can be driven to rotate. Through the rotation of one movable section 3, the limiting block 35 can be driven to slide inside the limiting groove 34. Through the cooperation between the limiting block 35 and the limiting groove 34, the movable section 3 can drive the adjacent movable section 3 to rotate, and thus multiple movable sections 3 can be unfolded.

[0038] Further, please refer to Figure 2 , Figure 3 , and Figure 9 , an airbag 4 covering the camera component 2 is arranged on the base 1. The airbag 4 is hemispherical in the inflated state. The airbag 4 is detachably installed on the base 1 through a fixing ring 5. By setting the airbag 4 to be detachable, the airbag 4 can be replaced when it is punctured. An air extraction device 6 for extracting the air in the airbag 4 is arranged on the base 1. The air in the airbag 4 can be extracted through the air extraction device 6. The airbag 4 is made of a transparent material, and the material of the airbag 4 can be nylon. When a micro-vibration occurs and the vibration sensor 13 senses that the vibration is not strong, the air extraction device 6 is started to evacuate the air inside the airbag 4. When the air inside the airbag 4 is evacuated, the airbag 4 will shrink and tightly adhere to the camera component 2, increasing the friction between the airbag 4 and the camera 2, thereby reducing the shaking of the camera caused by vibration. At the same time, the airbag 4 is made of a transparent material, so that the airbag 4 does not affect the normal shooting of the camera.

[0039] Specifically, please refer to Figure 6, the air extraction device 6 includes an air chamber 61 provided on the base 1. Inside the air chamber 61, there is a piston 62. The piston 62 is tightly connected to the inner wall of the air chamber 61 and can slide inside the air chamber 61. One end of the piston 62 is provided with a pushing device 63. Through the pushing device 63, the piston 62 can be pushed to slide inside the air chamber 61. At the end of the air chamber 61 away from the pushing device 63, there is a perforation 64 communicating with the inside of the airbag 4. By providing the perforation 64, the air inside the air chamber 61 can circulate with the air inside the airbag 4. The air extraction device 6 can refer to a syringe. When the pushing device 63 moves, the air inside the airbag 4 can be extracted through the perforation 64.

[0040] Specifically, please refer to Figure 6 , the pushing device 63 includes a pushing rod 631 provided at one end of the piston 62. The pushing rod 631 is provided with helical teeth 632. On the base 1, there is a second driving device 633. The output end of the second driving device 633 is provided with a first gear 634 adapted to the helical teeth 632. The second driving device 633 is a motor. When the motor rotates, it can drive the first gear 634 to rotate. The rotation of the first gear 634 and the cooperation with the gear 632 can make the pushing rod 631 move. By the movement of the pushing rod 631, the piston 62 can be pushed to move.

[0041] Furthermore, please refer to Figure 10 , on the base 1, there is a wire passing hole 7. By providing the wire passing hole 7, the camera wiring can be enabled. Inside the wire passing hole 7, there is a sealing plate 8. The sealing plate 8 can seal the serial hole 7. Inside the sealing plate 8, there is a through hole 10 for the wire 9 to pass through. Between the through hole 10 and the wire 9, there is a sealing component 11 for improving airtightness. The sealing component 11 can be a rubber part or a latex part, which fills the gap between the wire 9 and the through hole 10. By passing the wire 9 through the through hole 10 and setting the sealing component 10 between the wire 9 and the through hole 10, the sealing performance of the wiring can be improved, preventing air leakage at the wiring of the camera.

[0042] Specifically, please refer to Figure 5 and Figure 8, the camera assembly 2 includes a mounting shell 21 which is disposed on the base 1. The mounting shell 21 is rotatably connected to the base 1, enabling the camera to rotate in the horizontal direction. A recess 22 is provided at the edge of the mounting shell 21. The perforation 64 is designed above the recess 22. At least two ribs 23 are provided at the edge of the recess 22, and there is a gap between adjacent ribs 23. When the perforation 64 evacuates the air inside the airbag 4, the ribs 23 can prevent the airbag 4 from closing the perforation 64, thus affecting the air extraction effect of the air extraction device 6 on the inside of the airbag 4. A glass cover 24 is rotatably connected to the mounting shell 21. The camera body 25 is fixed inside the glass cover 24. A toothed disk 26 is provided on one side of the glass cover 24, and a second gear 27 is engaged with the toothed disk 26. A third driving device 28 for driving the second gear 27 to rotate is provided on the mounting shell 21. The third driving device 28 is a motor. When the third driving device 28 rotates, it can drive the second gear 27 to rotate. The rotation of the second gear 27 can drive the toothed disk 26 to rotate, causing the toothed disk 26 to drive the glass cover 24 to rotate, so that the glass cover 24 can drive the camera body 25 to adjust the angle. By providing the glass cover, it can prevent the airbag 4 from directly contacting the camera and prevent the airbag 4 from contaminating the lens of the camera.

[0043] Preferably, both the fixed section 31 and the movable section 32 are made of rigid materials. The movable section 32 can be made of rigid plastic or metal material, as long as it can prevent the camera from being knocked and damaged.

[0044] Specifically, the fixing ring 5 is threadedly connected to the base 1. The airbag 4 is provided with an opening, and the fixing ring 5 is provided with a pressing rib 51 for fixing the edge of the opening to the base 1. By rotating the fixing ring 5, the fixing ring 5 can drive the pressing rib 51 to move, pressing the edge of the opening of the airbag 4 onto the base 1, thereby fixing the airbag 4 to the base 1. When the airbag is damaged, the airbag 4 can be disassembled and replaced by rotating the fixing ring 5 in the reverse direction.

[0045] Furthermore, mounting ears 12 that can be fixed to the wall are provided on the base 1. By providing the mounting ears 12, the device can be fixed to the wall.
