Description

Technical Field

[0001] This application relates to the field of electric control technology, and in particular to control systems and optical devices. Background Technology

[0002] Some optical devices include adjustable optical elements. For example, zoom lenses include zoom lenses that need to be moved along the optical axis.

[0003] To control such adjustable optical elements, an adjustment system is required. Traditional mechanical adjustment systems have a large range of motion, often requiring the fingers to move a wide angle to achieve the desired adjustment distance, which is time-consuming and laborious.

[0004] Furthermore, mechanical adjustment systems are often designed for specific optical devices. For optical devices requiring multiple different optical parameters, the different sizes of optical components prevent the use of the same structural components, thus increasing material complexity and raising the overall technical and manufacturing difficulty. Utility Model Content

[0005] Therefore, it is necessary to provide adjustment systems and optical devices to address at least one of the above-mentioned problems.

[0006] In a first aspect, this application provides an adjustment system for adjusting an adjustable component. The adjustment system includes: a housing; a roller assembly rotatably connected to the housing, including a roller and a code disk, the roller being driven to the code disk, the roller at least partially protruding from the housing, the code disk being located within the housing; an encoder for identifying the code disk; a motor disposed in the housing and electrically connected to the encoder, the motor including an output terminal; and a transmission coupling member driven to the output terminal of the motor for controlled movement relative to the housing and for driving the adjustable component.

[0007] By setting up a housing and roller assembly, manual two-way operation can be achieved, realizing complex functions with a relatively integrated structure; furthermore, by using an encoder and motor, it is possible to customize the distance that the motor drives for each roller rotation, and to customize and adapt to the adjustment needs of different scenarios; the encoder and motor can be connected using components such as wires whose design structure can be easily modified, making the transmission components easy to modify and adapt to different adjustable components, reducing the difficulty of technical implementation.

[0008] In some embodiments, the housing includes a roller chamber recessed from the outside in, the roller chamber including a first sidewall and a second sidewall disposed opposite to each other; the roller is at least partially disposed in the roller chamber; the roller assembly further includes a roller and a sealing ring, the roller passing through the first sidewall and rotatably connected to the second sidewall; the sealing ring is sleeved on the roller and disposed at the first sidewall; the roller and the code disk are respectively sleeved on the roller and driven by the roller.

[0009] With this configuration, the housing can be sealed, and the movement of the inner transmission components can be achieved by manipulating the rollers on the outside. The overall structure of the roller assembly is relatively simple and the force transmission is stable.

[0010] In some embodiments, the adjustment system further includes a button disposed within the housing, and a roller is used to trigger the button; the roller is connected to a ball joint on the second side wall, and the sealing ring is elastically deformable along the radial direction of the roller.

[0011] This setup allows for the integration of more functions; the overall structure of the adjustment system remains relatively compact and occupies little space.

[0012] In some implementations, the control system further includes a communication module for transmitting signals, which is electrically connected to the encoder.

[0013] This setting allows the encoder to be edited and adjusted externally.

[0014] In some embodiments, the output end is a screw, and the transmission fitting includes a slider threaded to the screw and a ball head structure fixed to the slider; or, the motor is a linear motor, and the transmission fitting includes a slider fixed to the output end and a ball head structure fixed to the slider.

[0015] This configuration enables linear motion of the transmission components.

[0016] In some embodiments, the transmission coupling is configured to slide relative to the housing in a first direction, and the motor body and roller assembly are sequentially arranged on one side of the transmission coupling along the first direction.

[0017] This configuration results in a smaller radial dimension of the transmission mechanism, making it suitable for slender installation spaces.

[0018] Secondly, this application provides an optical device, including: an optical module including adjustable components; and the aforementioned adjustment system, wherein the optical module is disposed in a housing.

[0019] By setting up an adjustment system, the optical module can be adjusted; optical devices with different optical parameters can be designed, with low material complexity and low technical difficulty.

[0020] In some embodiments, the optical module includes an optical lens and a detector assembly, one of which includes an adjustable component; the optical module has an optical axis, and the detector of the detector assembly is disposed along the optical axis on the image side of the optical lens; the adjustment system is disposed along the optical axis on the image side of the optical lens.

[0021] This design allows for the creation of slender structures, enabling the production of smaller diameter optical devices to meet the needs of handheld devices, resulting in a better grip experience.

[0022] In some embodiments, the optical module includes an optical lens and a detector assembly, wherein the detector of the detector assembly is disposed on the image side of the optical lens along the optical axis of the optical module; the detector assembly is an adjustable component.

[0023] This setup allows for the manipulation of the rollers to adjust the optical module, including the optical focal length, to achieve the desired detection effect.

[0024] In some embodiments, the optical module includes an optical lens and a detector assembly, wherein the detector of the detector assembly is disposed on the image side of the optical lens along the optical axis; the optical lens includes an adjustable lens group that is adjustable along the optical axis, and the adjustable lens group is an adjustable component.

[0025] This setup allows for simultaneous adjustment of optical focal length and optical magnification by manipulating the scroll wheel. Attached Figure Description

[0038] refer to Figure 1 , Figure 1 An optical device according to an embodiment of this application is shown. For ease of description, a spatial rectangular coordinate system XYZ is established, where the X-axis direction can be parallel to a first direction.

[0039] Optical device 2000 may include optical module 2100 and adjustment system 1000. Optical module 2100 includes adjustable components, and adjustment system 1000 is used to adjust the adjustable components. Optical module 2100 may also include fixed components; or it may include a second adjustable component, which may be referred to as the first adjustable component.

[0040] Combination Figure 2 As shown, Figure 2 An adjustment system 1000 is shown in an embodiment of this application. In some embodiments, the adjustment system 1000 includes a housing 1, a roller assembly 2, an encoder 3, a motor 4, and a transmission coupling component 5.

[0041] The housing 1 may include multiple detachable parts. The housing 1 of the adjustment system 1000 may also refer to part of the overall housing of the optical device 2000.

[0042] The roller assembly 2 is rotatably connected to the housing 1, with a portion located outside the housing 1 and a portion located inside the housing 1. The roller assembly 2 includes a roller 21 and a code disk 22. The roller 21 is drive-connected to the code disk 22. Exemplarily, the roller 21 and the code disk 22 are coaxially arranged to achieve synchronous movement. The roller 21 at least partially protrudes from the housing 1, allowing the user to control the roller 21 from the outside of the housing 1. The code disk 22 is located inside the housing 1, protecting the code disk 22 and ensuring its safe and precise operation.

[0043] The encoder 3 is used to identify the code disk 22. The adjustment system 1000 may include a circuit board on which the encoder 3 may be mounted. The circuit board may also contain other electronic components.

[0044] The housing 1 and roller assembly 2 enable manual bidirectional operation, eliminating the need for a complex and error-prone two-button solution and achieving complex functions with a more integrated structure. The encoder 3 can recognize the forward and reverse rotation of the code disk 22, enabling control in both directions.

[0045] For example, the adjustment system 1000 also includes a communication module for transmitting signals. This communication module can be a wireless communication module or a communication interface. The communication module is electrically connected to the encoder 3. An external computer can connect to the encoder 3 through the communication module and edit and adjust the encoder 3 from the outside. The encoder 3 can generate control signals after recognizing the code disk 22. The drive distance of the motor 4 corresponding to one tooth of the code disk 22 can be customized.

[0046] Motor 4 is mounted on housing 1. Encoder 3 and motor 4 can be connected via wires or other components. This design allows for easy modification of the structure in different types of optical equipment 2000, reducing material complexity and technical implementation difficulty, and enabling customization to meet the adjustment needs of different scenarios. Motor 4 includes an output end 41. The fixed end of motor 4 can be fixed to housing 1. Output end 41 can output power.

[0047] The transmission component 5 is connected to the output end 41 of the motor 4.

[0048] In some embodiments, the output terminal 41 is a screw, and the axis of the screw may be parallel to the X-axis. The body 40 of the motor 4 can drive the screw to rotate. (Reference) Figure 1 The transmission mating component 5 may include a slider 51 threadedly connected to the screw and a ball head structure 52 fixed to the slider 51. The slider 51 may also be constrained by a track, or the ball head structure 52 may be constrained by the installed transmission mating component, enabling the transmission mating component 5 to move linearly.

[0049] In other embodiments, motor 4 may be a linear motor, with output terminal 41 outputting linear motion. The transmission coupling component 5 includes a slider 51 fixed to the output terminal and a ball-end structure 52 fixed to the slider 51, enabling linear motion of the transmission coupling component 5.

[0050] The ball head structure 52 can absorb a certain amount of error; for example, a slight rotational deviation along the YZ plane will not affect the linear motion along the X-axis.

[0051] The transmission coupling component 5 is used for controlled movement relative to the housing 1 and for driving adjustable components. The motor 4 and the transmission coupling component 5 can be flexibly adjusted to achieve electric control, making the transmission coupling component 5 easy to modify and adapt to different adjustable components.

[0052] refer to Figure 2The housing 1 includes a roller chamber 11 recessed from the outside in, and the roller chamber 11 includes a first sidewall 111 and a second sidewall 112 disposed opposite to each other. The first sidewall 111 and the second sidewall 112 may be disposed opposite to each other along the X-axis direction. The space defined within the roller chamber 11 can be regarded as the external space of the housing 1. The roller 21 may be partially disposed within the roller chamber 11 and partially protrude from the housing 1.

[0053] The roller assembly 2 also includes a roller 23, which passes through the first sidewall 111. The section of the roller 23 extending outside the housing 1 can pass through the roller 21, and the section extending inside the housing 1 can pass through the encoder 22. The roller 21 and encoder 22 are respectively fitted onto the roller 23 and driven by the roller. The overall structure of the roller assembly 2 is relatively simple, and the force transmission is stable. In other embodiments, the roller 23 can be segmented, for example, each segment can be a single piece.

[0054] The roller 23 is rotatably connected to the second sidewall 112, which may have a sealed, complete wall panel and may be provided with a rotation groove. In some embodiments, the end of the roller 23 extending out of the housing 1 may, for example, be suspended in the air. The second sidewall 112 may increase the support for the roller 23 and improve the accuracy of its movement.

[0055] The material of roller 21 can have a better tactile feel. Roller 21 is detachable from roller 23, which facilitates the assembly and disassembly of adjustment system 1000.

[0056] The roller assembly 2 also includes a sealing ring 24. The sealing ring 24 is sleeved on the roller 23 and is located at the first side wall 111. The housing 1 can achieve a seal. By operating the roller 21 on the outside, the movement of the inner transmission mating part 5 can be realized.

[0057] The adjustment system 1000 may also include a button 6, which is disposed within the housing 1, for example, on a circuit board. The button 6 may be radially disposed on one side of the roller 23, and the roller assembly 2 may be used to trigger the button 6, or the roller 23 may be used to trigger the button 6.

[0058] To enable the roller 23 to move slightly in the radial direction, the roller 23 can be connected to the ball joint of the second sidewall 112. One end of the roller 23 can be a ball joint or a ball groove, and the second sidewall 112 can be provided with a ball groove or have a protruding ball joint. The ball groove can be a hemispherical groove. The sealing ring 24 can elastically deform in the radial direction of the roller 23. The roller 23 can swing based on the center of the ball joint. Along the Y-axis, the button 6 can be located on the side of the roller 23 facing away from the housing 1. Pressing the roller 21 can trigger the button 6. The adjustment system 1000 can integrate more functions; the overall structure is still relatively compact and occupies little space.

[0059] The roller assembly 2 may also include a push sleeve, which is rotatably connected to the roller 23. The push sleeve can then abut against the button 6, helping to prevent the roller 23 from rotating and rubbing against the surface of the button 6, thus improving its lifespan.

[0060] refer to Figure 1 The adjustable components of the adjustment system 1000 are movable along the X-axis. The transmission coupling 5 is configured to slide relative to the housing 1 along a first direction. The motor body 40 and the roller assembly 2 are sequentially arranged on one side of the transmission coupling 5 along the first direction. The radial dimension of the transmission mechanism on the output side of the motor 4 is small, making it suitable for slender installation spaces. The adjustment system 1000 occupies a small overall installation space.

[0061] The optical device 2000 provided in this application embodiment can be a handheld device. The optical device 2000 includes an optical module 2100 and the aforementioned adjustment system 1000. The operator can quickly and conveniently realize optical zoom or magnification of the handheld imaging device by operating only a single roller 21 in the integrated roller assembly 2. The embedded waterproof roller 21, in conjunction with the encoder 3, drives the motor 4, enhancing protection and extending its lifespan. The custom encoder 3 enables a custom optical adjustment rate to adapt to the optical adjustment needs in different scenarios. The roller 21, in conjunction with the encoder 3, can identify the positive and negative rotation directions of the roller 21, corresponding to the positive and negative optical adjustment directions.

[0062] refer to Figure 1 The optical module 2100 includes an optical lens 2110 and a detector assembly 2120. The optical module 2100 includes an adjustable component, which may be one of the optical lens 2110 and the detector assembly 2120. (Reference) Figure 1 and Figure 3 The detector assembly 2120 may be an adjustable assembly. For example, refer to... Figure 4 The optical lens 2110 may include adjustable components.

[0063] The optical lens 2110 of the optical module 2100 has an optical axis, which may be parallel to the X-axis. The optical lens 2110 may include a lens barrel and a lens disposed on the lens barrel. The detector assembly 2120 may include a detector 2121 and a bracket 2122, and the detector 2121 may be fixed to the bracket 2122. The detector 2121 is disposed on the image side of the optical lens 2110 along the optical axis.

[0064] The adjustment system 1000 is positioned along the optical axis on the image side of the optical lens 2110. Compared to embedding the motor 4 within the optical lens 2110 or radially positioning it around the outer periphery of the optical lens 2110, the optical device 2000 of this embodiment externally fixes the motor 4 to the tail end of the optical lens 2110, and it can be positioned close to the detector 2121, for example, closely attached to the mechanism component that directly fixes the detector 2121. The motor 4 is located between the optical lens 2110 and the roller assembly 2. This arrangement minimizes the diameter of the optical lens 2110. Since the optical lens 2110 is the most significant and direct factor affecting the radial dimension of the optical device 2000, minimizing the radial dimension of the optical device 2000 results in a better grip for handheld devices. Simultaneously, this arrangement facilitates the sharing of a single housing structure for optical lenses 2110 with different optical parameters, increasing versatility and adaptability.

[0065] refer to Figure 3 The optical lens 2110 can be a fixed-focus lens. The detector assembly 2120 is an adjustable component that can slide along the optical axis to the optical lens 2110, ensuring that the detector 2121 always detects along the optical axis corresponding to the optical lens 2110, and can operate the roller 21 to adjust the optical focal length.

[0066] The ball head structure 52 can be embedded in the groove on the side of the bracket 2122. The tail of the optical lens 2110 can be cylindrical, and the bracket 2122 can include a cylindrical part sleeved on the optical lens 2110 to ensure that the detector 2121 always coincides with the optical axis.

[0067] Detector 2121 can be an infrared detector, and optical device 2000 can be a thermal imager.

[0068] For example, the slider 51 may have two fins 53, and the adjustment system 1000 may also include two interruptors 7. The interruptor 7 is used to limit the stroke of the transmission coupling 5, and the interruptor 7 may be a non-contact optical interruptor. When the fin 53 moves to the corresponding interruptor 7, the motor 4 stops outputting, and the transmission coupling 5 and the adjustable component stop at the specified position.

[0069] refer to Figure 4The optical lens 2110 can be a zoom lens and may include an adjustable lens group 2112 for zooming. The optical lens 2110 may include a fixing component 2111, which may include a lens barrel and a fixed lens group. A detector assembly 2120 may be fixed to the lens barrel. The detector 2121 is positioned along the optical axis on the image side of the optical lens 2110. The adjustable lens group 2112 is adjustable along the optical axis and may be connected to a connecting rod. As an adjustable component, the ball joint structure 52 of the transmission coupling 5 can be connected to the connecting rod to indirectly control the sliding position of the adjustable lens group 2112. The operator can manipulate the roller 21 to simultaneously adjust the optical focal length and optical magnification.

[0070] The technical features of the above-disclosed embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The embodiments disclosed above merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of patent protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of patent protection claimed by this application. Therefore, the scope of patent protection of this application should be determined by the appended claims.
