DETAILED DESCRIPTION
[0027] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.
[0028] Example 1
[0029] This embodiment 1 provides an optical camera with a built-in miniature automatic nitrogen filling structure, such as Figure 1-3 As shown, it includes a camera body 1, wherein a placement cavity 11 is provided inside the camera body 1, and an inflatable component, wherein the inflatable component includes a high-pressure gas cylinder 2 that can be placed in the placement cavity 11, a steering gear 3, and an electric control component 4;
[0030] The high-pressure gas cylinder 2 has a charging port at one end and a deflation port at the other end; a pressing deflation portion 21 is connected to the end of the high-pressure gas cylinder 2 close to the deflation port;
[0031] The steering gear 3 includes a telescopic portion that abuts against the pressing and releasing portion 21;
[0032] The electric control unit 4 is installed at the bottom of the steering gear 3 and is used to control the extension and retraction of the telescopic part.
[0033] In the prior art, as time passes, internal nitrogen and external air slowly penetrate, causing internal nitrogen concentration and pressure to decrease, thereby losing the protective effect on the surface of the optical mirror, thereby shortening the service life of the optical mirror.
[0034] In order to solve the above problems, the present application provides an inflatable component, which detects the closed internal pressure of the optical chamber through the electrical control component 4. When the pressure drops to a critical point, the telescopic part of the servo 3 drives the high-pressure gas cylinder 2 to press the deflation part 21 to deflate to replenish nitrogen, thereby greatly extending the service life of the optical camera product.
[0035] Specifically, the working process of this embodiment is as follows:
[0036] A camera module and an optical lens are arranged on one side of the camera body 1. The camera module collects normal data and takes photos of the outside world through the optical lens;
[0037] like Figure 3 As shown, when in use, the high-pressure gas cylinder 2 is installed on the steering gear 3 and the deflation part 21 is pressed against the telescopic part of the steering gear 3; the electric control component 4 is installed at the bottom of the steering gear 3, and the installed inflatable component is placed in the placement cavity 11.
[0038] like Figure 2 As shown, the high-pressure gas cylinder 2 is a miniature gas cylinder, which stores compressed liquefied gas for filling. One end of the high-pressure gas cylinder 2 is provided with a gas filling port for filling the high-pressure gas cylinder 2. Specifically, in order to facilitate the filling and sealing of the high-pressure gas cylinder 2, the high-pressure gas cylinder 2 is connected with a gas filling nozzle 22 at one end close to the gas filling port, and a sealing cap 23 is connected between the gas filling nozzle 22 and the high-pressure gas cylinder 2. Before starting to use, the staff can fill and store the high-pressure gas cylinder 2 through the gas filling nozzle 22, and the sealing cap 23 ensures the sealing of the high-pressure gas cylinder 2.
[0039] The other end is provided with a deflation port and a press-deflation part 21 for inflating the placement chamber 11. The telescopic part of the servo 3 abuts against the press-deflation part 21 of the high-pressure gas cylinder 2 to control the deflation or closing of the high-pressure gas cylinder 2, and the electric control part 4 controls the telescopic part to be extended or retracted; specifically, when the telescopic part is extended, the telescopic part drives the press-deflation part 21 to move and communicate with the inside of the high-pressure gas cylinder 2 to deflate, and when the telescopic part is retracted, the press-deflation part 21 is reset and isolated from the inside of the high-pressure gas cylinder 2 to stop deflation.
[0040] Specifically, in order to ensure the durability of the high-pressure gas cylinder 2, it is configured as follows: the high-pressure gas cylinder 2 is made of stainless steel, so that the compressed liquefied gas can be better stored.
[0041] Furthermore, to ensure the initial nitrogen filling process of the optical camera, e.g. Figure 2 As shown, the configuration is as follows: an inflation screw 7 and an exhaust screw 8 communicating with the placement cavity 11 are installed on the camera body 1 .
[0042] Specifically, the working process is as follows: in the initial state, the optical camera is inflated with nitrogen by the inflating screw 7 on the side wall of the optical camera, and the exhaust screw 8 is opened while inflating the nitrogen to exhaust the initial air inside the placement cavity 11. After the process of replacing the internal air with the inflated nitrogen is completed, the exhaust screw 8 is closed, and the nitrogen is continued to be inflated until the internal pressure reaches the value to be set and then the nitrogen is stopped.
[0043] Furthermore, in order to ensure the airtightness of the placement cavity 11, it is configured as follows: an upper cover plate 5 is installed on the top of the camera body 1, and a sealing ring 6 is connected between the upper cover plate 5 and the placement cavity 11. The sealing ring 6 is provided to ensure that the upper cover plate 5 is tightly connected to the bottom of the placement cavity 11, so as to improve the airtightness of the placement cavity 11 and slow down the loss rate of nitrogen.
[0044] Further, if Figure 4 As shown, the press-to-release portion 21 includes a sliding stopper 211 and a fixed sleeve 212, one end of the sliding stopper 211 is abutted against the telescopic portion, and the other end is connected to a baffle 214 for cooperating with the release port; a side of the sliding stopper 211 close to the baffle 214 is also provided with a release channel 215 connected to the inside of the high-pressure gas cylinder 2; the sliding stopper 211 is slidably connected to the fixed sleeve 212, and an elastic member is connected between the sliding stopper 211 and the fixed sleeve 212 to enable the baffle 214 to open or close the release port.
[0045] The working process of this embodiment is as follows: in the initial state, one end of the sliding block 211 is against the telescopic part of the steering gear 3, and the telescopic part is telescopically pressed against the sliding block 211, and the sliding block 211 moves toward the side of the high-pressure gas cylinder 2. At this time, the elastic member is compressed, and the baffle 214 is separated from the venting port, so that the venting channel 215 is connected to the inside of the high-pressure gas cylinder 2, and nitrogen is discharged from the venting channel 215.
[0046] The telescopic part is retracted, and the compressed spring 213 drives the sliding block 211 to return to its original position. At this time, the baffle 214 just fits in with the venting port to seal it so that the nitrogen gas no longer flows.
[0047] Furthermore, the elastic member is a spring 213. In this embodiment, the spring 213 plays a role in resetting the sliding stopper 211.
[0048] Furthermore, the telescopic portion includes a telescopic stopper 31, which abuts against the sliding stopper 211 and is provided with a plurality of deflation holes 311 connected to the deflation channel 215. In order to ensure that the nitrogen in the high-pressure gas cylinder 2 can be quickly released, in this embodiment, the nitrogen is released from the deflation channel 215 and then flows out from the plurality of deflation holes 311 and released into the placement cavity 11.
[0049] Further optimization, such as Figure 3 As shown, the electric control component 4 includes a control base plate 41 connected to the bottom of the servo 3, and a controller 42, an air pressure sensor 43 and a rechargeable battery 44 are arranged on the control base plate 41. The controller 42 is simultaneously connected to the air pressure sensor 43 and the servo 3 for communication, and the rechargeable battery 44 is connected to the controller 42 and the air pressure sensor 43.
[0050] Specifically, the rechargeable battery 44 supplies power to the controller 42 and the air pressure sensor 43. The air pressure value inside the placement cavity 11 is monitored by the air pressure sensor 43, and then compared with the set value. When the detected air pressure value is lower than the set value, the controller 42 controls the telescopic block 31 of the servo 3 to work, and the telescopic block 31 presses the sliding block 211 to open the venting port of the high-pressure gas cylinder 2 to fill the optical camera cavity with nitrogen. When the air pressure value reaches the set value, the controller 42 controls the telescopic block 31 of the servo 3 to retract, and the sliding block 211 automatically resets and stops filling nitrogen under the action of the spring 213. In addition, the air pressure sensor 43 performs cyclic detection of the internal air pressure value at a fixed time interval. The model of the controller in this embodiment is STM32, the model of the air pressure sensor is XGZP040, and the model of the servo is MG90S. All three are existing devices and will not be repeated here.
[0051] Further, if Figure 3 As shown, the control base plate 41 is connected to the bottom of the steering gear 3 through a bolt assembly. In this embodiment, the bolt assembly includes four bolts, which are respectively distributed on four sides of the control base plate 41 and connected to the bottom of the steering gear 3.
[0052] The specific working process of the utility model is:
[0053] A camera module and an optical lens are arranged on one side of the camera body 1. The camera module collects normal data and takes photos of the outside world through the optical lens;
[0054] When in use, the high-pressure gas cylinder 2 is installed on the steering gear 3 and the sliding block 211 is abutted against the telescopic block 31 of the steering gear 3; the electric control component 4 is installed at the bottom of the steering gear 3, and the installed inflatable component is placed in the placement cavity 11.
[0055] In the initial state, the optical camera is inflated with nitrogen by the inflating screw 7 on the side wall of the optical camera, and the exhaust screw 8 is opened while inflating the nitrogen to exhaust the initial air inside the placement cavity 11. After the process of replacing the internal air with nitrogen is completed, the exhaust screw 8 is closed and the nitrogen is continued to be inflated until the internal pressure reaches the value to be set and then the nitrogen is stopped.
[0056] Afterwards, the air pressure value inside the placement cavity 11 is monitored by the air pressure sensor 43, and then compared with the set value. When the detected air pressure value is lower than the set value, the controller 42 controls the telescopic block 31 of the servo 3 to work, and the telescopic block 31 presses the sliding block 211 and drives the sliding block 211 to move, and the baffle 214 is separated from the venting port, so that the venting channel 215 is connected to the inside of the high-pressure gas cylinder 2, and nitrogen is discharged from the venting channel 215 to fill the inside of the optical camera cavity with nitrogen. When the air pressure value reaches the set value, the controller 42 controls the telescopic block 31 of the servo 3 to retract, and the sliding block 211 automatically resets under the action of the spring 213 and stops filling with nitrogen. In addition, the air pressure sensor 43 performs cyclic detection of the internal air pressure value at fixed time intervals.
[0057] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
