Description

Technical Field

[0001] The present invention relates to the technical field of camera equipment, and in particular to a camera heating and defogging device. Background Art

[0002] A camera is a video input device with basic functions such as video photography, transmission and static image capture. In the era of intelligent data development, cameras can be seen everywhere in our daily lives. Some cameras installed outdoors will face greater temperature differences during use, which will cause the light-transmitting glass on the front side of the camera to fog up, thereby affecting image acquisition. Existing processing methods mostly use heating to achieve defog effects.

[0003] However, the existing cameras lack sealing detection during use, and the sealing effect is poor. When the sealing of the camera is damaged, the damage to the internal components will be aggravated. The existing camera heating and defogger device will continue to work without ensuring the sealing of the camera. When the sealing is damaged, the water vapor will not only fog up on the outside of the light-transmitting glass, but also enter the camera and fog up on the inside of the light-transmitting glass. After the heating and defogger is turned on, the volatilization of the water vapor accumulated on the light-transmitting glass will be accelerated, and then the contact between the internal water vapor and the internal components of the camera will be accelerated, thereby aggravating the damage to the internal components. At the same time, the water vapor will leave water marks on the light-transmitting glass after evaporation. The water marks on the outside can be cleaned regularly by wiping, but the water marks left on the inside of the light-transmitting glass due to heating after the sealing is damaged cannot be cleaned. After a long period of accumulation, the image will be blurred, and it cannot be repaired independently and can only be disassembled. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the above-mentioned traditional cameras lack sealing detection. When the sealing of the camera is destroyed, the damage to the internal components will be aggravated. After the sealing is destroyed, continuing to heat and defog will accelerate the contact between the internal water vapor and the internal components of the camera, and at the same time, water marks will accumulate on the inside of the light-transmitting glass, resulting in blurred imaging. The present invention provides a camera heating and defogger device.

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

[0006] A camera heating and defogging device comprises a shell and a mounting frame, wherein the mounting frame is hinged at the bottom of the shell, the front side of the shell is fixedly connected to a sealing ring, a push rod is slidably connected to the outer side of the sealing ring inside the front side of the shell, a spring is fixedly connected between the rear end of the push rod and the inner wall of the shell, there are four groups of push rods and springs, which are evenly distributed up and down and left and right inside the front side of the shell, an electric shock clip is fixedly installed above the sealing ring on the front side of the shell, and the electric shock clip is connected to the power supply unit inside the shell, a sealing heating component is provided on the front side of the shell, the sealing heating component is used to achieve the sealing of the shell and can heat itself, and a vacuum suction component is provided at the bottom of the front side of the shell, the vacuum suction component is used to form a vacuum environment inside the shell.

[0007] Furthermore, the front side portion of the push rod is made of rubber material to avoid scratching the connecting ring when contacting the connecting ring.

[0008] Furthermore, the sealed heating assembly includes a cover body, which is sleeved on the front side of the shell and fixed by bolts. The front side of the cover body is fixedly connected to the sealing ring 2 by a limit position. The cover body is slidably connected to a connecting ring by a limit position. The connecting ring is fixedly connected to a light-transmitting glass by a limit position. The light-transmitting glass adopts high-transmittance glass, which is conducive to the conduction of heat and light. The outer periphery of the light-transmitting glass inside the connecting ring is connected with a PI heating film for targeted heating of the light-transmitting glass. A plug is provided at the top of the rear side of the connecting ring. The plug is recessed inside the connecting ring. The plug is electrically connected to the PI heating film and aligned with the electric contact clip, so that the plug can be plugged into the electric contact clip to energize the PI heating film. Ring grooves are provided on the front and back sides of the connecting ring.

[0009] Furthermore, the annular grooves on the front and rear sides are aligned with the sealing ring 2 and the sealing ring 1 respectively, and are adapted to the sealing ring 2 and the sealing ring 1, so that when the connecting ring is in contact with the shell and the cover body, sealing can be achieved through the action of the annular grooves and the sealing rings 1 and 2.

[0010] Furthermore, the vacuum suction assembly includes a suction pipe, a suction pipe is fixedly installed at the bottom of the shell, the suction pipe is connected to the inside of the shell and can suck the air inside the shell, a cross pipe is fixedly connected to the middle part of the suction pipe, the empty pipe part on the left side of the cross pipe is connected to the suction pipe, and a plunger is slidably connected to the inside of the cross pipe cavity, the diameter of the plunger is larger than the diameter of the internal cavity of the suction pipe, so when the plunger moves to the connection between the suction pipe and the cross pipe, the suction pipe can also be blocked, the bottom of the suction pipe and the rear side of the cross pipe are both sleeved with sealing covers, and a connecting block is fixedly installed on the front side of the suction pipe at the bottom of the shell, and the bottom of the connecting block The lower part and the top part are respectively limited and slidably connected with the lower rack rod and the upper rack rod, and the lower rack rod and the upper rack rod are adjacent to each other. A gear is rotatably connected between the lower rack rod and the upper rack rod inside the connecting block, and the upper and lower sides of the gear are meshed with the racks adjacent to the lower rack rod and the upper rack rod. Therefore, when any one of the lower rack rod and the upper rack rod moves, the other can be moved in the opposite direction through the action of the gear. The moving stroke of the lower rack rod and the upper rack rod drives the gear to rotate half a circle, and a pointer is rotatably connected to the front side of the connecting block, and the rotating shaft of the pointer is transmission-connected to the axis of the gear, so that the rotation of the gear can drive the pointer to rotate.

[0011] Furthermore, the rear side of the lower rack rod is cylindrical, and is extended and limitedly slidably connected to the central interior of the cross tube. The front side of the upper rack rod is bent upward and fixedly connected to the push rod located below the shell, and a groove is provided at the bottom of the shell for the front side bend of the upper rack rod to slide back and forth, so that the movement of the push rod can drive the upper rack rod to move, and the movement of the lower rack rod can push the plunger inside the cross tube.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The present invention, through the design of a sealed heating component, cooperates with the push rod and the electric contact clip in the shell, and can achieve a sealed environment inside the camera. At the same time, the high-transmittance glass in the connecting ring and the PI heating film can be used to quickly heat and defog the translucent glass to ensure the normal use of the camera. When the sealing is damaged, the connecting ring will move to the front side after losing the effect of atmospheric pressure, and while ensuring basic sealing, it will disconnect the heating of the PI heating film, thereby avoiding the situation that after water vapor enters the interior of the camera, reheating will accelerate the contact between the internal water vapor and the internal components of the camera, thereby aggravating the damage of the internal components. At the same time, water vapor will accumulate water marks on the inside of the translucent glass, which cannot be effectively cleaned, thereby causing blurred imaging.

[0014] 2. The present invention, through the design of the vacuum suction component, cooperates with the push rod in the shell, can evacuate the shell and effectively seal it, thereby avoiding damage to the internal components of the camera and ensuring the normal operation of the camera. In the process of evacuating the inside of the shell, by utilizing the atmospheric pressure, it is only necessary to use the peripheral air suction equipment at the bottom of the suction pipe. After completion, it is automatically sealed, which is easy to operate. It can also issue an alarm after the sealing is damaged, facilitating timely maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] A camera heating and defogging device according to a preferred embodiment of the present invention will be described in detail below. Figure 1-12 As shown, a camera heating and defogging device comprises a shell 1 and a mounting frame 2, wherein the mounting frame 2 is limited and hinged at the bottom of the shell 1, a sealing ring 101 is fixedly connected to the front side of the shell 1, a push rod 102 is slidably connected to the outer side of the sealing ring 101 inside the front side of the shell 1, the front side part of the push rod 102 is made of rubber material to avoid scratching the connecting ring 33 when contacting with the connecting ring 33, a spring 103 is fixedly connected between the rear end of the push rod 102 and the inner wall of the shell 1, and there are four groups of push rods 102 and springs 103, which are evenly distributed up and down and left and right inside the front side of the shell 1, an electric shock clip 104 is fixedly installed above the sealing ring 101 on the front side of the shell 1, and the electric shock clip 104 is connected to the power supply unit inside the shell 1, a sealing heating component 3 is arranged on the front side of the shell 1, and the sealing heating component 3 is used to achieve the sealing of the shell 1 and can heat itself, and a vacuum suction component 4 is arranged at the bottom of the front side of the shell 1, and the vacuum suction component 4 is used to form a vacuum environment inside the shell 1.

[0030] The sealed heating assembly 3 includes a cover body 31, which is sleeved on the front side of the shell 1 and fixed by bolts. The front side of the cover body 31 is fixedly connected to a sealing ring 32, and the cover body 31 is internally limited and slidably connected to a connecting ring 33. The connecting ring 33 is internally limited and fixedly connected to a light-transmitting glass 34. The light-transmitting glass 34 is made of high-transmittance glass, which is conducive to the conduction of heat and light. The outer periphery of the light-transmitting glass 34 inside the connecting ring 33 is surrounded by a PI heating film 35 for targeted heating of the light-transmitting glass 34. A plug 36 is provided on the top of the rear side of the connecting ring 33, and the plug 36 is concave. The connecting ring 33 is shaped and arranged inside the connecting ring 33. The plug 36 is electrically connected to the PI heating film 35 and is aligned with the electric contact clip 104, so that the plug 36 can be plugged into the electric contact clip 104, and then the PI heating film 35 is energized. The connecting ring 33 is provided with annular grooves 37 on the front and rear sides. The annular grooves 37 on the front and rear sides are respectively aligned with the sealing ring 2 32 and the sealing ring 1 101, and are adapted to the sealing ring 2 32 and the sealing ring 1 101, so that when the connecting ring 33 is in contact with the shell 1 and the cover body 31, sealing can be achieved through the action of the annular grooves 37, the sealing ring 1 101 and the sealing ring 2 32.

[0031] The vacuum suction assembly 4 includes a suction pipe 41. The suction pipe 41 is fixedly installed at the bottom of the shell 1. The suction pipe 41 is connected to the inside of the shell 1 and can suck the air inside the shell 1. A cross pipe 42 is fixedly connected to the middle of the suction pipe 41. The empty pipe part on the left side of the cross pipe 42 is connected to the suction pipe 41. A plunger 43 is connected to the inner limit sliding connection of the cavity of the cross pipe 42. The diameter of the plunger 43 is larger than the diameter of the inner cavity of the suction pipe 41. Therefore, when the plunger 43 moves to the connection between the suction pipe 41 and the cross pipe 42, the suction pipe 41 can also be blocked. The bottom of the suction pipe 41 and the rear side of the cross pipe 42 are both sleeved with a sealing cover 44. A connecting block 45 is fixedly installed on the front side of the suction pipe 41 at the bottom of the shell 1. The bottom and top of the connecting block 45 are respectively The lower rack rod 46 and the upper rack rod 47 are connected with limited sliding, and a rack is arranged adjacent to the lower rack rod 46 and the upper rack rod 47. A gear 48 is rotatably connected between the lower rack rod 46 and the upper rack rod 47 inside the connecting block 45. The upper and lower sides of the gear 48 are meshed with the racks adjacent to the lower rack rod 46 and the upper rack rod 47. Therefore, when any one of the lower rack rod 46 and the upper rack rod 47 moves, the other can be moved in the opposite direction through the action of the gear 48. The moving stroke of the lower rack rod 46 and the upper rack rod 47 drives the gear 48 to rotate half a circle. The front side of the connecting block 45 is rotatably connected with a pointer 49, and the rotating shaft of the pointer 49 is transmission-connected to the axis of the gear 48, so that the rotation of the gear 48 can drive the pointer 49 to rotate.

[0032] The rear side of the lower rack rod 46 is cylindrical, and is extended and limitedly slidably connected to the central interior of the cross tube 42. The front side of the upper rack rod 47 is bent upward and fixedly connected to the push rod 102 located below the shell 1, and a groove is provided at the bottom of the shell 1 for the upper rack rod 47 to slide back and forth at the bent front side, so that the movement of the push rod 102 can drive the upper rack rod 47 to move, and the movement of the lower rack rod 46 can push the plunger 43 inside the cross tube 42.

[0033] The working principle of the present invention is:

[0034] Under normal working conditions, the interior of the shell 1 is a vacuum environment. Under the action of atmospheric pressure, the connecting ring 33 inside the cover body 31 will compress the push rod 102 backwards and attach it to the front side of the shell 1. The ring groove 37 on the rear side of the connecting ring 33 cooperates with the sealing ring 101 on the front side of the shell 1 to seal the joint between the connecting ring 33 and the shell 1. At the same time, the plug 36 on the connecting ring 33 will also be plugged into the electric contact clip 104 to realize the power supply to the PI heating film 35. At the same time, the lower rack rod 46 in the vacuum suction assembly 4 will be on the right side, and the plunger 43 will block the suction pipe 41 to ensure the vacuum environment inside the shell 1. When water mist appears on the light-transmitting glass 34, the PI heating film 35 will heat the light-transmitting glass 34 through the control of the electronic control unit. Combined with the high transmittance design of the light-transmitting glass 34, the light-transmitting glass 34 can be quickly defogged.

[0035] When the vacuum environment inside the shell 1 is destroyed, there will be no pressure difference between the front and rear sides of the connecting ring 33, and the push rod 102 will move forward under the action of the restoring force of the spring 103, thereby moving the connecting ring 33 forward and attaching it to the front edge of the cover body 31. The cooperation between the ring groove 37 on the front side of the connecting ring 33 and the sealing ring 32 on the front side of the cover body 31 ensures the sealing of the connecting ring 33 and the cover body 31 to prevent the entry of excess water vapor. At this time, the plug 36 on the connecting ring 33 will also be separated from the electric shock clamp 104, so that the PI heating film 35 will no longer heat when the sealing is destroyed. The forward movement of the push rod 102 at the bottom will drive the upper rack rod 47 to move forward through the fixed connection with the upper rack rod 47, and the meshing connection of the gear 48 between the upper rack rod 47 and the lower rack rod 46 can be used. It drives the lower rack rod 46 to move backward, and then pushes the plunger 43 in the cross tube 42 backward, unblocking the suction tube 41, which is beneficial to the next vacuum suction. Under the action of the sealing cover 44, excess water vapor cannot enter from the suction tube 41 and the cross tube 42. After the upper rack rod 47 and the lower rack rod 46 complete the misaligned movement, they will also drive the gear 48 to rotate half a circle, and then drive the pointer 49 to point in the opposite direction, indicating that the camera sealing is damaged. After the camera sealing is damaged, it can ensure that no excess water vapor enters, so that the camera can still be used. At the same time, the heating device is turned off to avoid aggravating the damage to internal components after heating the internal water vapor, and accumulating water marks on the inside of the light-transmitting glass 34 that cannot be cleaned. At the same time, maintenance personnel will be able to perform sealing inspection in time in advance.

[0036] After the inspection is completed, when it is necessary to re-create the vacuum environment inside the shell 1, first open the two sealing covers 44, and then connect an external exhaust device to the bottom of the suction pipe 41 to extract the air inside the shell 1. As the air inside the shell 1 decreases, the connecting ring 33 will move backward under the action of atmospheric pressure until it is reattached to the front side wall of the shell 1, and the PI heating film 35 will be powered on again. The backward movement of the connecting ring 33 will also push the push rod 102 to compress the spring 103 and move backward, and the push rod 102 at the bottom will also drive the upper rack rod 4 7 moves backward, and under the action of the gear 48, drives the lower rack rod 46 to move forward, so that the lower rack rod 46 releases the limit on the plunger 43, and the pointer 49 will also return to its position. In the process of forming the vacuum environment inside the shell 1, the plunger 43 will also move forward under the action of the atmospheric pressure, and only after the connecting ring 33 is completely fitted with the shell 1 and the lower rack rod 46 is completely moved forward, the plunger 43 can move again to block the suction pipe 41 to ensure the formation of the vacuum environment inside the shell 1. After the operation is completed, the sealing cover 44 can be covered again.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
