[0025] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0026] The purpose of the utility model is achieved by the following methods:
[0027] (refer to Figure 2 , Figure 3 ) The lens assembly 7 includes a module bracket 71, a camera unit 72 and a lens cover 73. The lens cover 73 is fixedly mounted on the upper side of the right housing 22 by means of screws. The function of the lens cover 73 is to provide an installation base for the camera unit 72 and the module bracket 71. The lens cover 73 also includes a structural positioning column 731 and a snap-fit hole 732. The positioning column 731 is arranged on the four corners of the circumscribed circle on the bottom surface of the lens cover 73. Its function is to provide an installation direction for the lens cover 73 to be detachably mounted on the upper side of the right housing 22.
[0028] (refer to Figure 6 The technical feature of the present application is that the module bracket 71 is designed to be detachably mounted on the lens cover 73, so as to achieve the purpose of conveniently disassembling the camera unit 72, and facilitate maintenance and replacement. The snap-fit hole 732 is set at the midpoint of the front, back, left, and right directions of the lens cover 73, and its function is to cooperate with the snap-fit paddle 713 of the module bracket 71 for installation and fixing. (Refer to Figure 4) The module bracket 71 is snap-fitted and installed on the lens cover 73, and its function is to facilitate the disassembly of the camera unit 72. The module bracket 71 also includes a receiving groove 711, a snap-fit cover 712 and a snap-fit paddle 713. The receiving groove 711 is arranged at the center of the module bracket 71 and has a cubic groove structure. The receiving groove 711 is used to accommodate and install the camera unit 72. The snap-fit cover 712 covers the receiving groove 711, and it and the receiving groove 711 form an accommodating cavity for accommodating and installing the camera unit 72. The snap-fit paddle 713 is arranged at the end position of the module bracket 71 in the front, back, left and right directions. (Refer to Figure 7 , Figure 8 ) The engaging paddle 713 corresponds to the engaging hole 732 on the lens cover 73, and its function is to help the module bracket 71 to be engaged and installed on the lens cover 73. A chamfer 74 is provided at the edge where the engaging paddle 713 and the engaging hole 732 engage with each other, so as to facilitate the separation between the module bracket 71 and the lens cover 73. When the module bracket 71 is subjected to a pulling force to the right, the engaging paddle 713 is deformed under the action of the chamfer 74, thereby achieving the purpose of separation. Then, the entire module bracket 71 and the entire lens cover can be separated, so as to facilitate the removal of the camera unit 72. In addition to the design of the chamfer 74, this structure can also adopt an arc design for both. It can play the same role.
[0029] (refer to Figure 5 , Figure 6 ) The camera unit 72 is fixedly installed in the receiving groove 711. The function of the camera unit 72 is to convert the light signal captured by the camera device into an electrical signal and record it in the electronic component. The camera unit 72 structure also includes a photosensitive chip 721 and a small circuit board 722. The photosensitive chip 721 is welded on the small circuit board 722, which is a CMOS chip used to convert the light signal captured by the camera device into an electrical signal and upload it to the capacitor. The small circuit board 722 is fixedly installed in the receiving groove 711. Its function is to store the electrical signal converted by the photosensitive chip 721 in the capacitor, and after the printing step starts, the electrical signal in the capacitor is transmitted to the electronic control component 5 through a wire.
[0030] Example, (reference Figure 4 , Figure 6) The snap-fit cover 712 covers the accommodating groove 711, and there is a square notch on the rear side of the cubic structure formed by the two. The function of the square notch is to provide a channel for the wire to enter and exit. The left and right directions of the accommodating groove 711 are provided with right-angled trapezoidal structures in the front and back directions. The function of the snap-fit cover 712 is to cooperate with the square through holes on the snap-fit cover 712 so that the snap-fit cover 712 is snap-fitted and installed on the accommodating groove 711. The snap-fit cover 712 is provided with square through holes in the left and right directions and the front and back directions. The function of the snap-fit cover 712 is to cooperate with the right-angled trapezoidal structure on the accommodating groove 711 for fixed installation. The bottom of the accommodating groove 711 is also provided with a circular through hole, which is used to provide a channel for the camera unit 72 to capture light signals.
[0031] In order to facilitate understanding of the purpose and function of this embodiment, (refer to Figure 1 ) Now, the method of applying it to a camera is introduced. The camera includes a frame 1, a casing 2, a cover 3, a side cover 4, an electronic control component 5, a printing component 6 and a lens component 7. The function of the frame 1 is to provide a mounting base for various components of the camera device. The casing 2 is composed of a left casing 21 and a right casing 22. The left casing 21 is fixedly installed on the left side of the frame 1. The left casing 21 is used to install part of the electronic control component 5. The right casing 22 is fixedly installed on the right side of the frame 1. The function of the right casing 22 is to provide a mounting base for the lens component 7 and to protect the internal parts of the camera. The cover 3 is composed of an upper cover 31 and a lower cover 32. The upper cover 31 is fixedly installed on the upper end of the frame 1, and the upper cover 31 covers the frame 1 to form a accommodating space for accommodating part of the electronic control component 5. Its function is to protect the camera device Internal parts, the lower cover 32 is fixedly mounted on the lower end of the frame 1, and the function of the lower cover 32 is to encapsulate the lower end of the frame 1 to protect the printing component 6 inside the camera device. The side cover 4 is fixedly mounted on the front side of the frame 1, and is also provided with a knife edge, which is used to facilitate the user to tear off the imaged photos. The electronic control component 5 is used to control the movement of the components of each link of the entire camera device, and at the same time plays an interactive role in connecting the user and the camera device (since it is a common technology in the camera field, it will not be described in detail here). The printing component 6 is fixedly mounted inside the frame 1, and the printing component 6 is used to complete camera imaging. The lens component 7 is fixedly mounted at the center of the right housing 22, and its function is to convert the light signal captured by the camera lens into an electrical signal and transmit it to the printing component 6 for imaging.
[0032] When the user presses the shutter button, the internal electronic control component 5 drives the camera unit 72 to capture the light signal, and the photosensitive chip 721 converts the light signal into an electric signal and stores it in the small circuit board 722. After the storage is completed, the electronic control component 5 controls the small circuit board 722 to transmit the electric signal in the capacitor back to the electronic control component 5 through the wire. The analog / digital converter in the electronic control component 5 converts the electric signal into a digital signal, and the digital signal is compressed by the microprocessor in the electronic control component 5 and converted into a specific image file format and output to the printing component 6. The printing component 6 presents the image on the photo paper, and finally rolls it out from the knife edge of the side cover 4 and is torn off by the user.
