[0002] With the development of industry, cameras have become widely used in various fields, including industrial machinery and equipment, medical equipment, vehicles, and outdoor life. Making fixed-focus cameras adjustable in focus allows for quick focus and image clarity after replacing the object being measured. Currently, there are two main methods for adjusting focus on cameras on the market: the first involves adjusting the camera's front flange position, and the second involves adjusting the lens' focal length. The first method requires the use of external tools and requires removing the lens and other front accessories to adjust the flange's front-to-back position. This method also provides no real-time feedback on image clarity, requiring repeated adjustments to achieve a clear image. The second method requires an external adjustable lens, requiring additional space on the camera's front to accommodate the lens, and manual rotation of the lens barrel to achieve focus.

[0003] Therefore, in the prior art, focusing requires the use of external conditions other than the camera, which makes the operation more complicated. Utility Model Content

[0045] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0046] An embodiment of the present application discloses a camera that can be focused through its own control system without the need for external conditions, making operation more convenient.

[0047] The camera includes a housing 10, a display screen, operating buttons, a controller, a lens and a focusing module 20. The lens is mainly responsible for collecting light and focusing it onto the imaging component 23 of the focusing module 20, so that the imaging component 23 can convert the received light signal into an electrical signal. In this way, the controller can receive the electrical signal transmitted by the imaging component 23 and send it to the display screen. The display screen can convert the electrical signal into a visual image for the user to view the real-time picture. The operating buttons include various function buttons such as the shutter button, mode dial, power switch and menu button, so that the focusing module 20 can be controlled by the controller to achieve focusing operations or other operations such as shooting.

[0048] refer to Figures 1 to 3 , the focusing module 20 is installed inside the housing 10 .

[0049] The housing 10 has an optical window 130 ; a lens is mounted on the optical window 130 .

[0050] The focusing module 20 includes a driving component 22 and an imaging component 23 connected to each other;

[0051] The imaging component 23 is opposite to the optical window 130 , and the optical axis of the lens coincides with the optical axis of the imaging component 23 .

[0052] The driving assembly 22 is used to drive the imaging assembly 23 to move relative to the housing 10 to change the distance between the imaging assembly 23 and the optical window 130 .

[0053] In this way, by setting a focusing module 20 in the housing 10, the driving component 22 in the focusing module 20 is connected to the imaging component 23. Since the imaging component 23 is opposite to the optical window 130 of the housing 10, the distance between the imaging component 23 and the optical window 130 can be adjusted by controlling the driving component 22, that is, the distance between the imaging component 23 and the lens can be changed, so that the focusing function can be conveniently realized without relying on conditions other than the camera itself, eliminating the need for disassembly and assembly operations.

[0054] Optionally, in this embodiment, the focusing module 20 also includes a carrying component, the carrying component is fixedly connected to the outer shell 10, the inner shell 21 is fixed to the outer shell 10, and the driving component 220 is fixed to the carrying component. In this way, when assembling the camera, the driving component 22, the imaging component 23 and the carrying component can be assembled into an integral focusing module 20 first, and then the entire focusing module 20 can be assembled into the outer shell 10 through the connection between the carrying component and the outer shell 10, thereby realizing modular assembly, which is more convenient and quick.

[0055] Among them, the carrying component includes an inner shell 21, the inner cavity of the inner shell 21 is connected to the optical window 130, and the driving component 22 is connected to the inner shell 21. At least part of the driving component 22 and / or at least part of the imaging component 23 are located inside the inner shell 21. In this way, when assembling the camera, the entire focusing module 20 can be assembled and then installed in the outer shell 10, and the entire focusing module 20 is protected by the outer shell 10.

[0056] In detail, the outer shell 10 and the inner shell 21 are both roughly cylindrical. The outer shell 10 includes a first outer shell 11, a middle shell 12, and a second outer shell 13 connected in sequence. The second outer shell 13 is provided with an optical window 130. The inner shell 21 includes a second inner shell 211 and a first inner shell 210 that are fixedly connected. The second inner shell 211 is fixedly connected to the second outer shell 13 of the outer shell 10, and the inner cavity of the second inner shell 211 is connected to the optical window 130. For example, a transition window 2110 with a diameter equal to or slightly larger than the diameter of the optical window 130 can be provided at the end of the second inner shell 211 away from the first inner shell 210. This can prevent the second inner shell 211 from blocking light and affecting imaging. The drive assembly 22 is fixedly connected to the first inner shell 210. In this way, after the focusing module 20 is assembled, it is fixed to the second outer shell 13, and then the middle shell 12 is fixed to the second outer shell 13. Finally, the first outer shell 11 is fixed to complete the assembly.

[0057] The connection method between any two adjacent members of the first outer shell 11, the middle shell 12, and the second outer shell 13 is not specifically limited, and may be connected by fasteners such as screws and rivets, or by a snap-fit ​​connection. The connection method between the second inner shell 211 and the first inner shell 210 is not specifically limited, and may be connected by first fasteners 30 (such as screws, rivets, etc.), or by a snap-fit ​​connection.

[0058] Combine Figures 2 to 5 The driving component 22 includes a driving member 220 and a guide shaft 221; the guide shaft 221 is passed through the imaging component 23; the driving member 220 is connected to the imaging component 23, and the driving member 220 is used to drive the imaging component 23 to slide along the length direction of the guide shaft 221, thereby achieving focusing, wherein the guide shaft 221 plays a guiding role in limiting the moving direction of the imaging component 23, ensuring that the optical axis of the imaging component 23 coincides with the optical axis of the lens, and ensuring clear imaging.

[0059] The supporting component has a first limiting groove and a second limiting groove that are relatively arranged, that is, there are relative first limiting grooves and second limiting grooves on the inner wall of the inner shell 21. Specifically, the first limiting groove and the second limiting groove are respectively arranged on the inner end walls of the first inner shell 210 and the second inner shell 211 at one end away from each other. The line between the center of the first limiting groove and the center of the second limiting groove is parallel to the optical axis of the optical window 130. The two ends of the guide shaft 221 are respectively inserted into the first limiting groove and the second limiting groove, thereby realizing the position fixation of the guide shaft 221 and ensuring the accuracy of the linear movement of the imaging component 23.

[0060] Among them, there is no specific restriction on the number of guide shafts 221, as long as the number of the first limiting groove, the second limiting groove and the guide shaft 221 can be ensured to be the same, the first limiting groove, the second limiting groove and the guide shaft 221 correspond one to one to ensure the linear movement accuracy of the imaging component 23. For example, in this embodiment, there are two, and the corresponding first limiting grooves and second limiting grooves are also two. The two ends of each guide shaft 221 are respectively inserted into a first limiting groove and a second limiting groove. In this way, by passing through the imaging component 23 with more than two guide shafts 221, the imaging component 23 can only move linearly along the length direction of the guide shaft 221, thereby avoiding the swing of the imaging component 23 and improving the positioning accuracy.

[0061] The driving member 220 includes a motor module, which is selected from one of a screw motor module, a hydraulic motor module, a rack and pinion motor module, and a motor synchronous belt module.

[0062] Taking the screw motor module as an example, the driving part 220 includes a screw motor module, and the screw motor module includes a fixing frame 2200, a motor 2201 and a screw 2202; the fixing frame 2200 is fixed to the inner shell 21, specifically, a connecting beam 2101 is formed inside the first inner shell 210 of the inner shell 21, and a second fastener 31 such as a screw or rivet passes through the fixing frame 2200 and is locked into the connecting beam 2101 formed inside the first inner shell 210. The number of the connecting beams 2101 can be two, so that the fixing frame 2200 is fixed to the connecting beam 2101.

[0063] The screw rod 2202 can be rotatably arranged on the fixing frame 2200; the motor 2201 is fixed to the fixing frame 2200 and connected to the screw rod 2202, so that the motor 2201 and the screw rod 2202 are installed to the first inner shell 210 of the inner shell 21 through the fixing frame 2200, and the motor 2201 is used to drive the screw rod 2202 to rotate; the imaging component 23 is threadedly connected to the screw rod 2202.

[0064] In this way, the rotation of the lead screw 2202 generates a spiral transmission to convert the torque of the motor 2201 into a linear driving force and transmit it to the imaging component 23, thereby realizing the linear movement of the imaging component 23, and the linear movement direction of the imaging component 23 is achieved by changing the rotation direction of the motor 2201. For example, when the motor 2201 is controlled to rotate forward by the operation button, the imaging component 23 gradually moves away from the optical window 130 and the lens. When the motor 2201 is controlled to rotate backward by the operation button, the imaging component 23 gradually approaches the optical window 130 and the lens, thereby realizing the focusing function.

[0065] Optionally, the first inner shell 210 of the inner shell 21 has an avoidance gap 2102, and both the driving component 22 and the bracket 230 of the imaging component 23 can partially extend out of the inner shell 21 through the avoidance gap 2102, that is, the driving component 22 and the imaging component 23 are partially located inside the inner shell 21. This can reduce the length of the entire focusing module 20, and then reduce the length of the entire camera, reduce the space occupied in the camera, improve the compactness of the structure, and also facilitate the second fastener 31 to be driven from the side to connect the fixing frame 2200 and the connecting beam 2101.

[0066] The connecting beam 2101 also partially extends out of the avoidance gap 2102 to ensure that there are sufficient connection points between the fixing frame 2200 and the connecting beam 2101, thereby ensuring connection reliability.

[0067] Since the first inner shell 210 is provided with an avoidance gap 2102, the strength of the first inner shell 210 will be insufficient. Therefore, in this embodiment, the focusing module 20 also includes an annular fixing part 40, which is fixed to the part of the first inner shell 210 of the inner shell 21 where the avoidance gap 2102 is formed by a fourth fastener 33 such as screws and rivets. Parts of the driving component 22 and the imaging component 23 can pass through the fixing part 40. In this way, the strength of the first inner shell 210 can be improved by the annular fixing part 40, thereby ensuring the service life of the camera.

[0068] In order to realize the spiral transmission between the screw rod 2202 and the imaging assembly 23, the imaging assembly 23 is connected with a claw 50. Figure 6 The claw 50 has an internal threaded portion 51, which is threadedly matched with the screw rod 2202. In this way, the claw 50 is connected to the driving member 220, and the driving member 220 can drive the bracket 230 to move linearly by driving the claw 50. That is, when the motor 2201 drives the screw rod 2202 to rotate, the claw 50 is restricted by the imaging component 23 and cannot rotate. Therefore, the internal threaded portion 51 can generate a spiral motion with the screw rod 2202, and the claw 50 moves linearly accordingly.

[0069] The imaging assembly 23 includes a bracket 230 and a chip module 231 and a filter holder 232 fixed to the bracket 230 near the optical window 130. The chip module 231 is farther away from the optical window 130 than the filter holder 232. A third fastener 32 such as a screw or rivet passes through the chip module 231 and the filter holder 232 in sequence and is locked into the bracket 230 to realize the assembly of the imaging assembly 23. The chip module 231 receives light in a wavelength range selectively passed through the filter holder 232 to convert the optical signal into an electrical signal to ensure the color accuracy and consistency of the final generated image.

[0070] The guide shaft 221 passes through the bracket 230, the chip module 231 and the filter holder 232. The part of the bracket 230 away from the chip module 231 is connected to the claw 50, so that the driving member 220 can drive the bracket 230 to move linearly by driving the claw 50.

[0071] In detail, the number of guide shafts 221 is more than two as shown in the figure, which includes a first shaft 2210 and a second shaft 2211. The bracket 230 is provided with a through hole 2303 and a matching groove 2304. The length directions of the through hole 2303 and the matching groove 2304 are both in the same direction as the optical axis of the lens. The first shaft 2210 is passed through the through hole 2303, and the second shaft 2211 is slidably matched with the matching groove 2304. In this way, it is only necessary to pass the first shaft 2210 into the through hole 2303, and the second shaft 2211 is installed into the matching groove 2304 from the side, which is convenient for assembly.

[0072] The bracket 230 has a slot 2300, which passes through the side wall of the bracket 230 facing the screw rod 2202, and the slot 2300 is respectively provided with sockets 2301 on the two side walls opposite to each other in the length direction of the guide shaft 221; the claw 50 has an insertion rod 52, and the two ends of the insertion rod 52 are respectively inserted into the two sockets 2301, so that the insertion rod 52 cannot move relative to the bracket 230, and because the internal threaded portion 51 of the claw 50 is threadedly connected to the screw rod 2202, the claw 50 is also restricted in rotational freedom by the bracket 230 and the screw rod 2202 to ensure that the claw 50 and the screw rod 2202 produce spiral motion when the screw rod 2202 rotates.

[0073] Among them, one of the two opposite side walls of the slot 2300 is provided with a slide groove 2302 connected to the socket 2301, and the slide groove 2302 is used to guide one end of the insertion rod 52 to slide into a socket 2301, so that the claw 50 can be easily installed on the bracket 230.

[0074] Of course, in some embodiments, the imaging assembly 23 may not be provided with the filter holder 232. For example, the motor module is a rack and pinion motor module, with the rack fixed to the bracket 230. The motor 2201 converts torque into a linear driving force by driving the gear meshing with the rack. In this way, the torque provided by the motor 2201 can be converted into a linear driving force capable of driving the imaging assembly 23 to move linearly. The driving member 220 can also be an electric push rod, a linear motor 2201, or other mechanism capable of providing a linear driving force, as long as it can drive the imaging assembly 23 to move linearly.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
