Description

Technical Field

[0001] This invention relates to the field of infrared equipment technology, and in particular to an infrared device equipped with a rotational eccentricity compensation device. Background Technology

[0002] Since infrared night vision devices are generally used outdoors, it is not easy to find the operation buttons in dark environments; therefore, the more operation buttons there are, the less convenient it is to operate.

[0003] There are already infrared devices that use roller structures to achieve electronic display magnification.

[0004] However, existing infrared devices, which use both scroll wheel and button buttons on a single device, remain very inconvenient to operate. The existing scroll wheel design only implements the zoom function of the button buttons, lacking the functionality of short press for taking a photo and long press for recording video.

[0005] Therefore, there is a need to provide a new infrared device that integrates button functions on a scroll wheel to simplify operation and improve ease of use. Summary of the Invention

[0006] Based on the above analysis, the present invention aims to provide an infrared device equipped with a rotational eccentricity compensation device to solve the problem of inconvenient operation caused by the separate setting of press buttons and rotation buttons in existing infrared devices.

[0007] The objective of this invention is mainly achieved through the following technical solutions:

[0008] An infrared device equipped with a rotational eccentricity compensation device includes: a lens assembly, an encoder, an eccentricity compensation device, a drive device, a circuit board, and an infrared module; the eccentricity compensation device can output linear displacement and rotational angular displacement; the circuit board acts as a controller for the infrared module and the drive device; the encoder is used to monitor the magnitude of the rotational angular displacement output by the eccentricity compensation device; the encoder is connected to the circuit board, thereby enabling the circuit board to control the drive device; the drive device is used to adjust the lens spacing of the lens assembly; when the eccentricity compensation device outputs linear displacement, it can trigger a button on the circuit board.

[0009] Furthermore, the eccentricity compensation device includes: a rotating shaft, an eccentricity compensation component, and a pressing bracket; the eccentricity compensation component is installed on the housing of the infrared device; the rotating shaft is rotatably mounted on the eccentricity compensation component and is connected to the encoder; the rotating shaft achieves eccentric displacement through the elastic deformation of the eccentricity compensation component; the pressing bracket is provided with a rotating shaft mounting hole, and the rotating shaft and the rotating shaft mounting hole are clearance-fitted; the pressing bracket and the rotating shaft are synchronously displaced and can trigger the button on the main circuit board.

[0010] Furthermore, the eccentricity compensation device also includes: a roller; the roller is sleeved on the outside of the rotating shaft; when the roller rotates, it can drive the rotating shaft to rotate synchronously, and when the roller presses down, it can drive the rotating shaft and the pressing bracket to move down.

[0011] Furthermore, the eccentricity compensation component includes: a first compensation wheel and a second compensation wheel; both the first compensation wheel and the second compensation wheel are sleeved on the outside of the rotating shaft and are respectively disposed on both sides of the roller; the first compensation wheel and the second compensation wheel are rotatably mounted on the outer shell and are both elastic structures.

[0012] Furthermore, a first extension and a second extension are provided on the inner side of the outer casing; the first extension is provided with a first mounting hole for rotatably mounting the first compensation wheel, and the second extension is provided with a second mounting hole for rotatably mounting the second compensation wheel; when the rotating shaft is displaced, the first compensation wheel and the second compensation wheel undergo elastic deformation.

[0013] Furthermore, the eccentricity compensation assembly also includes: a first guide frame and a second guide frame; both the first guide frame and the second guide frame are fixedly installed inside the housing; a pressing bracket is slidably installed on the first guide frame; and an encoder is slidably installed on the second guide frame.

[0014] Furthermore, the first guide frame and the second guide frame have the same structure.

[0015] Furthermore, the second guide frame has a C-shaped structure, including: a guide main plate, a first side plate, and a second side plate; the first side plate and the second side plate are respectively disposed at both ends of the guide main plate and are perpendicular to the guide main plate; the first side plate and the second side plate are provided with two guide grooves in opposite positions.

[0016] Furthermore, the encoder bracket is slidably installed in the guide groove; the encoder is fixedly installed on the encoder bracket.

[0017] A method for controlling an infrared device, employing the aforementioned infrared device equipped with a rotational eccentricity compensation device; the control method includes the following steps:

[0018] Step S1: After the infrared device is started, the display screen of the infrared device can be adjusted by pressing the scroll wheel or rotating the scroll wheel;

[0019] Step S2: When it is necessary to take a photo or record a video, press down the roller, and the rotating shaft moves down synchronously and can drive the pressing bracket to move down; the pressing bracket triggers the button on the main board of the circuit to realize the photo or video recording operation;

[0020] Step S3: When the image needs to be zoomed, the roller is turned to rotate it; the roller drives the rotating shaft to rotate, and then the encoder and the main circuit board control the drive device to adjust the lens spacing of the lens assembly, thereby realizing the zooming of the output image of the infrared device.

[0021] The technical solution of this invention can achieve at least one of the following effects:

[0022] 1. When the rollers are rotated or pressed, the first and second compensation rollers always have interference fits around the mating surfaces of the rotating shaft. After rotation or pressing, the springs of the compensation rollers will push the rotating shaft and rollers back to their original positions, thus achieving accurate reset.

[0023] 2. The present invention employs a rotational eccentricity compensation structure, which enables the roller of the infrared device to simultaneously perform rolling and button functions and be waterproof, allowing each rotation to be close to the central axis of the device, thereby improving the lifespan of the device.

[0024] 3. This invention solves the problem of cumbersome zooming operations in infrared devices. Existing infrared devices zoom in and out via buttons; for example, a single button press zooms in or out by 0.1x, requiring 20 presses to zoom in or out by 2x, which is not a quick way to obtain the desired image. This invention uses a rotating roller to control a motor, which in turn moves the lens via gears to achieve electronic zooming. Rotating the roller clockwise zooms out, and rotating it counterclockwise zooms in, enabling continuous zooming.

[0025] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained from what is particularly pointed out in the description and drawings. Attached Figure Description

[0049] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0050] Example 1

[0051] A specific embodiment of the present invention discloses an infrared device equipped with a rotational eccentricity compensation device, such as... Figure 1 As shown, the system includes: a lens assembly 1, an encoder 2, an eccentricity compensation device 3, a drive device, a circuit board 4, and an infrared module 6; the eccentricity compensation device 3 can output linear displacement and rotational angular displacement; the circuit board 4 acts as the controller for the infrared module 6 and the drive device; the encoder 2 is used to monitor the magnitude of the rotational angular displacement output by the eccentricity compensation device 3; the encoder 2 is connected to the circuit board 4, and thus can control the drive device through the circuit board 4; the drive device is used to adjust the lens spacing of the lens assembly 1; when the eccentricity compensation device 3 outputs linear displacement, it can trigger a button on the circuit board 4.

[0052] The infrared device of the present invention outputs linear displacement and rotation angle through the eccentric compensation device 3, thereby realizing the adjustment of the infrared device display image; specifically, when the eccentric compensation device 3 outputs linear displacement, it can trigger the button of the circuit main board 4, thereby activating the infrared device screen to take a picture or record video by long press; when the eccentric compensation device 3 outputs rotational angular displacement, it can collect the magnitude of the angular displacement through the encoder 2, and then control the drive device through the circuit main board 4 to adjust the lens spacing of the lens assembly 1, thereby realizing the magnification and reduction functions of the infrared device display image.

[0053] It is worth noting that the infrared device of this invention refers to an infrared night vision device; the circuit board 4, infrared module 6, and other components of this invention are all existing components of infrared devices and can be matched using existing infrared device technologies. They will not be described in detail in this invention and will not affect the implementation of the technical solution of this invention.

[0054] like Figure 2 As shown, the eccentricity compensation device 3 includes: a rotating shaft 31, an eccentricity compensation component, and a pressing bracket 37; the eccentricity compensation component is installed on the housing 8 of the infrared device; the rotating shaft 31 is rotatably mounted on the eccentricity compensation component, and the rotating shaft 31 is connected to the encoder 2; the rotating shaft 31 achieves eccentric displacement through the elastic deformation of the eccentricity compensation component; the pressing bracket 37 is provided with a rotating shaft mounting hole 372, and the rotating shaft 31 is clearance-fitted with the rotating shaft mounting hole 372; the pressing bracket 37 and the rotating shaft 31 move synchronously, and can trigger the button on the circuit board 4.

[0055] Furthermore, such as Figure 2 As shown, the eccentricity compensation device 3 further includes: a roller 33; the roller 33 is sleeved on the outside of the rotating shaft 31; when the roller 33 rotates, it can drive the rotating shaft 31 to rotate synchronously; when the roller 33 presses down, it can drive the rotating shaft 31 and the pressing bracket 37 to move down.

[0056] In one specific embodiment of the present invention, the eccentricity compensation assembly includes: a first compensation wheel 32 and a second compensation wheel 34; both the first compensation wheel 32 and the second compensation wheel 34 are sleeved on the outside of the rotating shaft 31 and are respectively disposed on both sides of the roller 33; the first compensation wheel 32 and the second compensation wheel 34 are rotatably mounted on the outer casing 8 and are both elastic structures. The two compensation wheels function as bearings, enabling the rotation of the rotating shaft, while the first compensation wheel 32 and the second compensation wheel 34 are elastic structures, allowing the rotating shaft 31 to move vertically through elastic deformation.

[0057] In one specific embodiment of the present invention, a first extension and a second extension are provided on the inner side of the outer casing 8; the first extension is provided with a first mounting hole for rotatably mounting the first compensation wheel 32, and the second extension is provided with a second mounting hole for rotatably mounting the second compensation wheel 34; when the rotating shaft 31 is displaced, the first compensation wheel 32 and the second compensation wheel 34 undergo elastic deformation.

[0058] Specifically, such as Figure 2 As shown, both the first compensation wheel 32 and the second compensation wheel 34 are interference-fitted with the rotating shaft 31. When the roller 33 rotates, it can drive the first compensation wheel 32 and the second compensation wheel 34 to rotate synchronously. When the first compensation wheel 32 and the second compensation wheel 34 rotate, they rotate relative to the outer casing 8 respectively. At this time, the first compensation wheel 32 and the second compensation wheel 34 rotate rubbing in the first mounting hole and the second mounting hole respectively.

[0059] Furthermore, such as Figure 5 As shown, the rotation axis 31 is a multi-segment stepped axis; specifically, the rotation axis 31 includes a first axis segment 311, a second axis segment 312, a third axis segment 313, and a fourth axis segment 314 with decreasing diameters.

[0060] Specifically, the end of the first shaft segment 311 is provided with a shaft hole 315, and the encoder 2 is engaged with the shaft hole 315 of the rotating shaft 31; when the rotating shaft 31 rotates, the encoder 2 can record the rotation direction and rotation angle of the rotating shaft 31.

[0061] Specifically, such as Figure 2As shown, the first compensation wheel 32 is fitted onto the second shaft section 312 with an interference fit; one side of the first compensation wheel 32 is in contact with the shoulder end face between the first shaft section 311 and the second shaft section 312; the other side of the first compensation wheel 32 is in contact with the first extension of the outer casing 8; the eccentric compensation device 3 of the present invention achieves a sealed installation of the first compensation wheel 32 by setting the two sides of the first compensation wheel 32 to be in contact with the first shaft section 311 of the rotating shaft 31 and the first extension of the outer casing 8. When the first compensation wheel 32 rotates synchronously with the rotating shaft 31, it slides against the outer casing 8, maintaining the sealing effect on the first mounting hole.

[0062] Specifically, such as Figure 7 As shown, a U-shaped hole 331 is provided in the middle of the roller 33, and the roller 33 is installed on the third shaft section 313 of the rotating shaft; correspondingly, the third shaft section 313 is a U-shaped shaft; the third shaft section 313 of the rotating shaft 31 cooperates with the U-shaped hole 331 of the roller 33 so that the two can rotate and move synchronously. When the roller 33 is pressed down or rotated, the rotating shaft 31 is also pressed down or rotated synchronously.

[0063] Specifically, such as Figure 2 As shown, the second compensating wheel 34 is fitted onto the fourth shaft segment 314 of the rotating shaft 31 with an interference fit. One side of the second compensating wheel 34 makes sealing contact with the shoulder between the third shaft segment 313 and the fourth shaft segment 314, and the other side of the second compensating wheel 34 makes sealing contact with the sealing element 35, ensuring that the second compensating wheel 34 can always seal the second mounting hole when it rotates and deforms. When the second compensating wheel 34 rotates synchronously with the rotating shaft 31, the second compensating wheel 34 maintains sliding friction with the sealing element 35, thus achieving a seal on the second mounting hole.

[0064] Preferably, such as Figure 2 As shown, both the first mounting hole and the second mounting hole are stepped holes, so that the cylindrical side of the first compensating wheel 32 or the second compensating wheel 34 can mate with the large hole section of the first mounting hole or the second mounting hole, and one end face of the first compensating wheel 32 or the second compensating wheel 34 can fit against the stepped end face of the first mounting hole or the second mounting hole.

[0065] Specifically, the seal 35 is fixedly connected to the second extension of the housing 8 by welding or bonding; the seal 35 has a through hole in the middle, through which the fourth shaft segment 314 of the rotating shaft 31 passes and connects to the pressing bracket 37. Further, the diameter of the through hole is larger than the diameter of the fourth shaft segment 314 of the rotating shaft 31, reserving space to allow the rotating shaft 31 to move downwards, such as... Figure 2 As shown.

[0066] Since infrared night vision devices are generally used outdoors, they require high waterproofing capabilities. Not only must the device be waterproof when stationary, but it must also be waterproof during user operation. The infrared device of this invention, through the sealed installation of the first compensation wheel 32 and the second compensation wheel 34, maintains a constant seal on the infrared device during pressing or rotating operations of the roller 33, thus providing excellent waterproofing.

[0067] Specifically, the first compensation wheel 32 and the second compensation wheel 34 have the same structural composition.

[0068] In one specific embodiment of the present invention, such as Figure 6 As shown, the first compensation wheel 32 includes a rubber wheel body 321 and a spring 323. The rubber wheel body 321 is sleeved on the outside of the rotating shaft 31 with an interference fit. A circular groove 322 is provided on the side of the rubber wheel body 321, and a spring 323 is installed between the two sides of the groove 322. Specifically, multiple springs 323 are circumferentially arranged in the groove 322, and the axial direction of the springs 323 coincides with the radial direction of the rubber wheel body 321. When the roller 33 presses down, the rotating shaft 31 moves downward synchronously with the roller 33. The first compensation wheel 32 and the second compensation wheel 34 deform. The spring 323 located below the rotating shaft 31 is compressed, and the spring 323 located above the rotating shaft 31 is stretched. The eccentric deformation of the first compensation wheel 32 and the second compensation wheel 34 adapts to the displacement of the rotating shaft 31 while maintaining a sealing effect on the inner cavity of the equipment. Preferably, the rubber wheel body 321 is made of SR5570LB self-lubricating rubber.

[0069] When the rotating shaft 31 is pressed down, the compensating wheel should be able to deform smoothly, while avoiding deformation of the compensating wheel when the rotating roller 33 is rotated; therefore, it is necessary to avoid the roller 33 being difficult to press down or being accidentally pressed down. Preferably, the depth of the annular groove 322 is 1 / 2 to 2 / 3 of the thickness of the rubber wheel body 321.

[0070] In this invention, when the roller 33 rotates, the rotating shaft 31, the first compensation wheel 32, and the second compensation wheel 34 all rotate synchronously. The encoder 2 can collect the rotation angle and direction of the rotating shaft 31, and then control the lens assembly 1 to adjust the lens spacing through the circuit board 4, ultimately achieving a certain degree of magnification or reduction of the infrared display image. When the roller 33 is pressed down, the rotating shaft 31 moves downward synchronously with the roller 33, thereby driving the pressing bracket 37 to move and trigger the button on the circuit board 4, realizing short press to take a photo and long press to record a video.

[0071] Furthermore, in order to ensure the accuracy of the displacement direction of the rotating shaft 31, and thus the accuracy of the pressing position of the pressing bracket 37, a guide structure is also provided in this invention.

[0072] Specifically, such as Figure 2 As shown, the eccentricity compensation assembly further includes: a first guide frame 36 and a second guide frame 38. Both the first guide frame 36 and the second guide frame 38 are fixedly installed inside the housing 8; the pressing bracket 37 is slidably installed on the first guide frame 36; and the encoder 2 is slidably installed on the second guide frame 38.

[0073] Furthermore, such as Figure 8 , Figure 9 As shown, the second guide frame 38 has a C-shaped structure, including: a guide main plate, a first side plate and a second side plate; the first side plate and the second side plate are respectively disposed at both ends of the guide main plate and are perpendicular to the guide main plate; the first side plate and the second side plate are provided with two guide grooves 381 that are positioned opposite each other.

[0074] Furthermore, the encoder bracket 21 is slidably installed in the guide groove 381; the encoder 2 is fixedly installed on the encoder bracket 21.

[0075] Specifically, such as Figure 10 As shown, the encoder bracket 21 includes a first sliding plate 212 and an encoder mounting hole 211 disposed on the first sliding plate 212; specifically, the encoder mounting hole 211 is a threaded hole. The first sliding plate 212 has sliding portions at both ends that slide in cooperation with the guide groove 381. The first sliding plate 212 is slidably mounted in the guide groove 381, thereby slidably mounting the encoder bracket 21 on the second guide frame 38.

[0076] Furthermore, such as Figure 11 As shown, encoder 2 includes: encoder body 201, mounting threaded portion 202, and rotary switch 203; wherein, the mounting threaded portion 202 of encoder 2 is threadedly connected to the encoder mounting hole 211 of encoder bracket 21, so that encoder 2 is fixedly connected to encoder bracket 21; the rotary switch 203 of encoder 2 cooperates with the shaft hole 315 of rotating shaft 31 to realize the connection between encoder 2 and rotating shaft 31, so that encoder 2 can record the rotation direction and rotation angle of rotating shaft 31. When rotating shaft 31 moves down, encoder 2 and encoder bracket 21 move down synchronously, and encoder bracket 21 slides along guide groove 381 of second guide frame 38.

[0077] Furthermore, the first guide frame 36 and the second guide frame 38 have the same structure.

[0078] Specifically, such as Figure 12As shown, the pressing bracket 37 includes an integrally formed second sliding plate 371, a rotating shaft mounting hole 372, and a pressing part 373. The second sliding plate 371 is slidably mounted on the first guide frame 36, and the sliding direction of the second sliding plate 371 is perpendicular to the rotation axis of the rotating shaft 31. The rotating shaft mounting hole 372 is located in the middle of the second sliding plate 371, and the rotating shaft 31 is rotatably mounted in the rotating shaft mounting hole 372 with a clearance fit, allowing the rotating shaft 31 to rotate relative to the pressing bracket 37, and causing the pressing bracket 37 to move downwards synchronously when the rotating shaft 31 moves downwards.

[0079] Furthermore, a lower pressure plate is provided on the second sliding plate 371, the lower pressure plate is perpendicular to the second sliding plate 371 and has a protruding lower pressure part 373. In the infrared device of the present invention, when the lower pressure roller 33 causes the rotating shaft 31 to move downward, the pressing bracket 37 synchronously rotates the shaft 31 downward, and can trigger the button of the circuit main board 4 through the lower pressure part 373. That is, when the rotating shaft 31 moves downward, the lower pressure part 373 can press the button of the circuit main board 4, thereby realizing the functions of pressing to take pictures and long pressing to record videos of the infrared device.

[0080] In one specific embodiment of the present invention, such as Figure 3 , Figure 4 As shown, the lens assembly 1 includes: a lens positioning tube 11, an outer sleeve 12, a connecting pin 13, a first lens 14, a lens mounting base 15, and a second lens 16.

[0081] The first lens 14 is fixedly installed inside the lens positioning cylinder 11, and the second lens 16 is slidably installed inside the lens positioning cylinder 11 via the lens mounting base 15. Specifically, the lens mounting base 15 is slidably installed inside the lens positioning cylinder 11 and can slide along the axial direction of the lens positioning cylinder 11. The second lens 16 is fixedly installed on the lens mounting base 15 and can slide with the lens mounting base 15. When the lens mounting base 15 and the second lens 16 slide relative to the lens positioning cylinder 11, the distance between the first lens 14 and the second lens 16 can be changed, thereby enabling the display image of the infrared device to be magnified and reduced.

[0082] Specifically, an outer sleeve 12 is coaxially fitted around the lens positioning cylinder 11, and the outer sleeve 12 can rotate relative to the lens positioning cylinder 11 along its own axis. The outer sleeve 12 has a spiral groove 122, and a connecting pin 13 is disposed in the spiral groove 122 and passes through it to be fixedly connected to the lens mounting base 15. When the outer sleeve 12 rotates relative to the lens positioning cylinder 11, the connecting pin 13 slides relative to it in the spiral groove 122, and the connecting pin 13 and the lens mounting base 15 can move up and down under the pushing action of the spiral groove 122. During the up-and-down movement of the lens mounting base 15, the position of the second lens 16 can be adjusted, changing the distance between the first lens 14 and the second lens 16.

[0083] In one specific embodiment of the present invention, the driving device is a motor 5; a gear 7 is fixedly connected to the output shaft end of the motor 5; the gear 7 meshes with a toothed plate 121 integrally formed on the outside of the outer sleeve 12; when the motor 5 drives the gear 7 to rotate, the gear 7 meshes with the toothed plate 121 to drive the outer sleeve 12 to rotate; that is, the motor 5 can drive the outer sleeve 12 to rotate through the gear 7, and then push the connecting pin 13 and the lens mounting base 15 to move through the outer sleeve 12, thereby adjusting the distance between the first lens 14 and the second lens 16 and realizing the scaling of the display screen.

[0084] It is worth noting that: this invention is an improvement design of existing infrared devices; this invention does not describe the components and principles related to signal reception, processing and display of infrared devices, the above content belongs to the prior art of infrared devices, and will not be repeated in this invention, and will not affect the implementation of the technical solution of this invention.

[0085] Example 2

[0086] In one specific embodiment of the present invention, an improvement is made based on embodiment 1; a compensation wheel with a different structure is used to replace the compensation wheel in embodiment 1, but its installation method and setting position are the same as those of the compensation wheel in embodiment 1.

[0087] In this embodiment, the first compensation wheel 32 and the second compensation wheel 34 have the same structure, but different dimensions.

[0088] like Figure 13 As shown, the second compensation wheel 34 is coaxially arranged with an inner wheel body 341, an arc-shaped elastic ring 342, and a rubber ring 343 from the inside to the outside.

[0089] Specifically, the inner wheel body 341 and the rotating shaft 31 are fitted with an interference fit. Preferably, the inner wheel body 341 is made of rubber or soft metal.

[0090] Specifically, two symmetrically arranged arc-shaped elastic rings 342 are welded to the outside of the inner wheel body 341; the two arc-shaped elastic rings 342 are circular ring structures and can undergo elastic deformation. Preferably, the arc-shaped elastic rings 342 are made of rubber, silicone, or thin-walled metal.

[0091] Specifically, a rubber ring 343 is fixedly connected to the outside of the arc-shaped elastic ring 342, and the edge of the rubber ring 343 is fixedly connected to the outer edge of the arc-shaped elastic ring 342. Multiple circumferentially distributed elastic elements 344 are arranged in the annular cavity formed by the inner wheel body 341, the two symmetrically arranged arc-shaped elastic rings 342 and the rubber ring 343. When the rotating shaft 31 moves downward, the inner wheel body 341 moves synchronously, and the arc-shaped elastic ring 342 and the elastic elements 344 undergo elastic deformation to adapt to the eccentric displacement of the inner wheel body 341. The rubber ring 343 remains stationary or undergoes slight deformation. After the roller 33 is released, the rotating shaft 31 is reset under the elastic force of the elastic elements 344.

[0092] Preferably, the elastic element 344 is a second spring.

[0093] In this embodiment, the inner wheel body 341 is configured to be interference-fitted with the rotating shaft 31, and the eccentric deformation of the compensation wheel is mainly achieved by the deformation of the arc-shaped elastic ring 342 and the elastic element 344 set in the middle layer. During the deformation process, the inner wheel body 341 and the rubber ring 343 deform less, and no gap is generated between the inner wheel body 341 and the rotating shaft 31. The outer rubber ring 343 will also not generate a gap with the outer shell 8, ensuring that the compensation wheel has good sealing and waterproof performance.

[0094] Furthermore, the side of the inner wheel body 341 is in contact with the shoulder of the rotating shaft 31.

[0095] Furthermore, the rubber ring 343 makes sealing contact with the seal 35 and can slide relative to it through friction; or, the rubber ring 343 of the first compensating wheel 32 contacts the first extension of the outer casing 8 and can slide relative to it through friction. This embodiment achieves a good sealing effect and better waterproofing by placing the elastic element 344 within the cavity formed by the two arc-shaped elastic rings 342, and by having the inner wheel 341 and the rubber ring 343 contact the rotating shaft 31 or the outer casing 8 respectively.

[0096] Preferably, to ensure smooth rotation of the compensating wheel in the mounting hole, multiple metal balls (not shown in the figure) can be nested on the outer surfaces of the first compensating wheel 32 and the second compensating wheel 34. The metal balls on the first compensating wheel 32 or the second compensating wheel 34 contact the inner wall surface of the first mounting hole or the second mounting hole. When the first compensating wheel 32 and the second compensating wheel 34 rotate, the metal balls roll and displace along the inner wall surface of the first mounting hole or the second mounting hole. Preferably, the multiple metal balls are evenly distributed on the outer cylindrical surface of the first compensating wheel 32 or the second compensating wheel 34.

[0097] Example 3

[0098] A specific embodiment of the present invention provides a method for controlling an infrared device, employing an infrared device equipped with a rotational eccentricity compensation device; the control method includes the following steps:

[0099] Step S1: After the infrared device is started, the display screen of the infrared device can be adjusted by pressing the scroll wheel 33 and rotating the scroll wheel 33.

[0100] Step S2: When it is necessary to take a photo or record a video, press down the roller 33, and the rotating shaft 31 moves down synchronously and can drive the pressing bracket 37 to move down; the pressing bracket 37 triggers the button on the main board 4 of the circuit to realize the photo or video recording operation;

[0101] Step S3: When the image needs to be zoomed, the roller 33 is turned to rotate it; the roller 33 drives the rotating shaft 31 to rotate, and then the encoder 2 and the circuit board 4 control the drive device to adjust the lens spacing of the lens assembly 1, thereby realizing the zooming of the output image of the infrared device.

[0102] In step S2, when the roller 33 is pressed, due to the very small clearance between the pressing bracket 37 and the rotating shaft 31, the roller 33 drives the rotating shaft 31 to move downward, thereby causing the pressing bracket 37 to slide downward relative to the first guide frame 36. This presses the lower part 373 of the pressing bracket 37, triggering the switch on the main circuit board 4, thus realizing the button function. At this time, the encoder switch 2 is not triggered and slides downward along the guide groove 381 of the second guide frame 38 together with the encoder bracket 21. After pressing, the rebound force of the first compensation wheel 32 and the second compensation wheel 34 pushes the rotating shaft 31, encoder 2, encoder bracket 21, pressing bracket 37 and roller 33 back to their original positions.

[0103] In step S2, the spring 323, combined with the rebound force of the rubber itself, ensures that the internal components of the device will spring back into place after rotation or pressing. The SR5570LB self-lubricating rubber will release oil during rotation to reduce the frictional resistance of the compensation wheel, thereby improving the life of the compensation wheel and making the roller 33 feel better when rotating.

[0104] In step S3, when the roller 33 is rolled, the roller 33 drives the rotating shaft 31 to rotate together, thereby driving the encoder switch 203 to rotate. The encoder switch 203 converts the rotation amplitude and rotation direction into electrical signals, which are transmitted to the circuit main board 4 through the signal line. The circuit main board 4 controls the motor 5 to rotate and controls the lens spacing of the lens assembly 1 through the control line.

[0105] Specifically, in step S3, the lens spacing is adjusted as follows:

[0106] Step S31: Motor 5 drives gear 7 to rotate, and through the meshing of gear 7 and gear plate 121, drives outer sleeve 12 to rotate;

[0107] Step S32: During the rotation of the outer sleeve 12, the connecting pin 13 slides along the spiral groove 122, thereby pushing the connecting pin 13 and the lens mounting base 15 to move through the spiral groove 122 of the outer sleeve 12;

[0108] Step S33: When the lens mount 15 moves, it drives the second lens 16 to move, adjusting the distance between the first lens 14 and the second lens 16, thereby realizing the corresponding magnification or reduction command of the image.

[0109] In step S3, when the roller 33 is rotated, the pressing bracket 37 does not rotate because of the clearance fit with the rotating shaft 31, does not participate in the movement, and cannot trigger the switch on the circuit board 4.

[0110] Compared with the prior art, the technical solution provided by the present invention has at least one of the following beneficial effects:

[0111] The infrared device of the present invention uses a compensation wheel to realize the rotation and pressing action of the rotating shaft 31, integrating the functions of the pressing button and the scroll wheel button, reducing the number of operation buttons, and making it more convenient to operate without having to search for buttons when working at night; at the same time, the compensation wheel has a waterproof function, and after the movement is completed, the rebound force of the compensation wheel itself can return all the moved parts in the device to their original positions.

[0112] The infrared device of the present invention uses SR5570LB self-lubricating rubber at the joint between the compensation wheel and the rotating shaft. It has a self-lubricating function, which improves the fatigue life of the rubber parts and makes the roller 33 feel better.

[0113] The infrared device of the present invention restricts the five degrees of freedom of the pressing bracket 37 and the encoder bracket 21 in terms of front-back, left-right and rotation through the guide groove. After the pressing bracket 37 and the encoder bracket 21 are installed in the guide groove 381, they can only slide up and down, which ensures the accuracy of the displacement direction of the pressing bracket 37, and thus ensures that the buttons on the circuit board 4 can be pressed accurately.

[0114] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
