[0027] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0028] like Figure 1-7 As shown, a camera comprises a housing 1, wherein the housing 1 comprises a front housing 101 and a rear housing 102, wherein the front housing 101 and the rear housing 102 are fixedly connected by screws, and a cavity is formed inside the front housing 101 and the rear housing 102, so as to facilitate installation of other components. The housing 1 is arranged such that the front housing 101 and the rear housing 102 are detachable, which is convenient for both assembly and disassembly and maintenance. A lanyard hole 103 is provided on one side of the housing 1, and a lanyard can be inserted into the lanyard hole 103, so as to facilitate carrying the camera outside.

[0029] A control board 2 and a lens 3 are installed in the cavity in the housing 1. The lens 3 is electrically connected to the control board 2. One end of the lens 3 extends out of the front end surface of the housing 1. A contact switch 4 is provided on the control board 2. A dial mechanism 5 is provided in the housing 1. One end of the dial mechanism 5 extends out of the upper end surface of the housing 1. The dial mechanism 5 can be connected to the contact switch 4. When taking pictures, the user can operate the dial mechanism 5 to connect it with the contact switch 4, so that the contact switch 4 is turned on; at this time, the control board 2 will control the lens 3 to shoot and realize taking pictures. The imaging principle of the camera can adopt the imaging principle of existing digital cameras. Its specific structure and imaging principle will not be described in detail in this article.

[0030] Specifically, the dial mechanism 5 includes a dial bracket 51, which is fixedly mounted in the housing 1. The dial bracket 51 is fixedly mounted in the housing 1. A dial wheel 52, a shutter button 53 and a linkage 54 are provided on the dial bracket 51. The dial wheel 52 is rotatably connected to the dial bracket 51. One side of the dial wheel 52 extends out of the rear end surface of the housing 1. The shutter button 53 is movably limitedly connected to the dial bracket 51, and one end of the shutter button 53 extends out of the upper end surface of the housing 1. The linkage 54 is movably limitedly connected to the dial bracket 51. When taking a photo, the user can drive the linkage 54 by pressing the shutter button 53, so that the linkage 54 descends and connects with the contact switch 4, thereby triggering the contact switch 4; the contact switch 4 will feedback a signal to the control board 2, and the control board 2 controls the lens 3 to shoot after receiving the trigger signal, thereby completing the photo-taking action.

[0031] In order to improve the operating feel of a retro film camera, in this embodiment, a limit platform 521 is provided on the lower end surface of the toggle wheel 52, a limit notch 522 is provided on the limit platform 521, and a limit block 541 is provided on the linkage member 54. The limit block 541 is slidably matched with the limit platform 521, and the limit block 541 can be engaged with the limit notch 522. An elastic limit member 55 is provided on the dial wheel bracket 51, and a limit tooth 523 is provided on the outer wall of the toggle wheel 52. One end of the elastic limit member 55 is slidably engaged with the limit tooth 523. When the toggle wheel 52 is rotated, the elastic limit member 55 slides on the limit tooth 523, and the limit block 541 slides on the limit platform 521.

[0032] In the initial state, the limit block 541 is in contact with the limit platform 521; the user can rotate the toggle wheel 52 to make the elastic limit member 55 slide on the limit tooth 523, and the elastic limit member 55 is elastically deformed and engages with each limit tooth 523 in turn, making a "click" sound; when the toggle wheel 52 is rotated until the limit notch 522 is aligned with the limit block 541, the limit block 541 enters the limit notch 522 and engages with it, making a mechanical collision sound. The toggle wheel 52 can no longer be rotated; the user can then press the shutter button 53 to drive the linkage member 54 to move downward, so that the limit block 541 disengages from the limit notch 522 and re-engages with the limit platform 521; the toggle wheel 52 can continue to be rotated only after the limit block 541 disengages from the limit notch 522; at the same time, the linkage member 54 will connect with the contact switch 4 during the downward movement, thereby triggering a photo signal, and the control board 2 controls the lens 3 to take a photo, thereby completing a round of photo taking.

[0033] The camera adopts the imaging principle of a digital camera, so that the user can obtain high-definition photos. At the same time, through the cooperation of the toggle wheel 52, the linkage member 54 and the elastic limit member 55, it has the operating feel of a film camera. The user can hear a "click" sound by turning the toggle wheel 52, and the toggle wheel 52 can only be turned again after pressing the shutter button 53, which can satisfy the user's nostalgic feelings and enhance the user's usage experience.

[0034] In this embodiment, the limit platform 521 is a spiral ring structure, and a limit groove 524 is provided in the limit platform 521. A guide column 543 is provided at one end of the limit shift block 541. The guide column 543 extends into the limit groove 524 and slides with the inner wall of the limit groove 524. In the process of rotating the toggle wheel 52, the guide column 543 will slide on the inner wall of the limit groove 524. Through the cooperation between the guide column 543 and the limit groove 524, on the one hand, the linkage part 54 can be prevented from being separated from the toggle wheel 52, thereby improving the stability of the structure; on the other hand, the guide column 543 slides along the inner wall of the limit groove 524, and can also provide torque to the linkage part 54, so that the linkage part 54 can rotate.

[0035] In order to reset the linkage member 54, a torsion spring 56 is sleeved on the linkage member 54, and a rotation limit block 542 is provided on the linkage member 54. One end of the torsion spring 56 abuts against the rotation limit block 542, and the other end is connected to the dial bracket 51. The rotation limit block 542 can abut against the side wall of the dial bracket 51, and the torsion spring 56 can drive the linkage member 54 to move up and down and rotate. When the dial wheel 52 is rotated, the limit block 541 slides on the limit platform 521, and the guide column 543 slides along the inner wall of the limit groove 524 and drives the linkage member 54 to rotate, while squeezing the torsion spring 56; when the dial wheel 52 rotates to the limit position, the limit block 541 is inserted into the limit notch 522, and the user can take pictures by pressing the shutter button 53. When the user presses the shutter button 53, the shutter button 53 pushes the linkage member 54 downward, compressing the torsion spring 56; when the linkage member 54 drives the limit block 541 to disengage from the limit notch 522, the elastic force of the torsion spring 56 drives the linkage member 54 to rotate until the rotation limit block 542 abuts against the dial wheel bracket 51 and collides with it, making a "snap" sound, and the limit block 541 passes over the limit platform 521. When the user releases the shutter button 53, the elastic force of the torsion spring 56 pushes the linkage member 54 upward until the limit block 541 abuts against the limit platform 521, and then the user can continue to rotate the dial wheel 52 to make the limit block 541 slide on the limit platform 521. The torsion spring 56 can provide the linkage member 54 with driving force in both the rotation and ascending directions, so that the linkage member 54 can jump out of the limit notch 522 and abut against the limit platform 521.

[0036] The height of the limit platform 521 gradually increases along the rotation direction of the toggle wheel 52. When the user presses the shutter button 53, the limit block 541 is separated from the limit notch 522, and the linkage member 54 is driven to rotate under the elastic force of the torsion spring 56. After the linkage member 54 passes over the limit notch 522, the limit block 541 will abut against the lowest end of the limit platform 521; as the toggle wheel 52 rotates, the limit platform 521 abutting against the limit block 541 gradually rises, which will appropriately squeeze the limit block 541, thereby compressing the torsion spring 56, so that the force of the user to rotate the toggle wheel 52 also needs to be appropriately increased, so as to improve the user's hand feeling of rotating the toggle wheel 52.

[0037] In order to reset the shutter button 53, a reset spring 57 is provided on the shutter mounting frame, one end of the reset spring 57 is connected to the shutter button 53, and the other end is connected to the dial bracket 51, and the reset spring 57 is used to drive the shutter button 53 to move upward. In order to limit the shutter button 53, a limit buckle 531 is provided on the shutter button 53, and the limit buckle 531 passes through the dial bracket 51, and the limit buckle 531 can abut against the lower end surface of the dial bracket 51. When the user presses the shutter button 53, the shutter button 53 compresses the reset spring 57, and the limit buckle 531 extends back from the lower end surface of the dial bracket 51; when the user releases the shutter button 53, the shutter button 53 is pushed upward by the elastic force of the reset spring 57; the shutter button 53 drives the limit buckle 531 to move together until the limit buckle 531 abuts against the lower end surface of the dial bracket 51.

[0038] In this embodiment, the contact switch 4 includes a contact electrode 41 and an elastic electrode 42, and the contact electrode 41 and the elastic electrode 42 are respectively welded on the control board 2, and a gap is reserved between the elastic electrode 42 and the contact electrode 41. One end of the linkage member 54 extends out of the dial bracket 51 and can be connected with the elastic electrode 42, and the linkage member 54 can push the elastic electrode 42 to deform in the direction close to the contact electrode 41. Under normal circumstances, the contact electrode 41 and the elastic electrode 42 are separated from each other, and the two are not conductive. When the user presses the shutter button 53, the shutter button 53 pushes the linkage member 54 to descend, and the other end of the linkage member 54 extends out of the dial bracket 51 and connects with the elastic electrode 42. As the linkage member 54 continues to descend, the linkage member 54 will push the elastic electrode 42 to undergo elastic deformation until the elastic electrode 42 is connected with the contact electrode 41, and the two are conductive; feedback signals are sent to the control board 2, and after the control board 2 receives the conductive signal, the lens 3 is controlled to shoot, and the photo is completed. After the user releases the shutter button 53, the linkage member 54 is reset upward under the action of the torsion spring 56; at this time, the elastic pole piece 42 will also automatically reset under the action of its own elastic force, thereby separating from the contact pole piece 41 and resetting to the initial position.

[0039] A battery compartment 104 is provided in the housing 1. The battery compartment 104 is electrically connected to the control board 2. The battery compartment 104 is used to place batteries so as to power the control board 2 and realize the camera function. A battery cover 105 is installed on the battery compartment 104. The battery cover 105 is detachably connected to the housing 1. The battery compartment 104 can be exposed by opening the battery cover 105 so as to load and unload the batteries in the battery compartment 104. The battery cover 105 facilitates battery replacement and improves practicality.

[0040] In order to facilitate taking photos in dark places, a flashlight 6 is installed in the housing 1, and one end of the flashlight 6 extends out of the front face of the housing 1. The flashlight 6 is used to fill in the light when the user takes photos. Since the flashlight 6 requires a large voltage and current, it is necessary to store electricity before using the flashlight 6; in this embodiment, a flash charging switch 61 and a charging indicator light 62 are provided in the housing 1, and a circuit structure for charging the flashlight 6 is provided on the control board 2. The flashlight 6, the flash charging switch 61 and the charging indicator light 62 are electrically connected to the control board 2 respectively. When the flashlight 6 needs to be used, the user needs to press the flash charging switch 61 first, and then the battery will charge the flashlight 6 through the charging circuit, and the charging indicator light 62 will light up; when the charging indicator light 62 goes out, it means that the charging is completed at this time. After that, when the user presses the shutter button 53, the control board 2 controls the lens 3 to take photos while also controlling the flashlight 6 to work, and the flashlight 6 lights up to fill in the light for taking photos.

[0041] When the ambient light is sufficient, the flash charging switch 61 may not be pressed, and the flash 6 will not work when the user takes a photo. Such a design can effectively save battery power, thereby extending the battery life.

[0042] A slide switch 7 and a host indicator light 8 are installed in the housing 1. One end of the slide switch 7 and the host indicator light 8 extend out of the housing 1 respectively.
