[0049] Reference Figures 1 to 5 A camera device includes a rotating roller 1, a camera 2, a flexible circuit board 3, and a housing 4. The rotating roller 1 is disposed in the housing 4. The flexible circuit board 3 is elongated. The first end of the flexible circuit board 3 is connected to the camera 2, and the second end of the flexible circuit board 3 is connected to the rotating roller 1. The flexible circuit board 3 is arranged around the rotating roller 1 so that the camera 2 can be flexibly extended through the flexible circuit board 3.

[0050] With the above structural design, during use, pulling the camera or flexible circuit board causes the rotating roller to rotate in the extension direction, allowing the camera to flexibly extend along the flexible circuit board. During shooting, the housing can be placed in the desired position, making it more flexible and convenient to use. Furthermore, the flexible extension of the camera can be applied to a wider range of usage scenarios, especially for covert shooting in special situations. For example, the housing can be placed in a backpack, allowing the camera to extend to the backpack opening for easy shooting; alternatively, the housing can be placed in a clothing pocket, allowing the camera to extend to the pocket opening for easy shooting. Of course, users can place the camera according to their needs, and various usage scenarios will not be listed here.

[0051] After use, the flexible circuit board is repositioned around the rotating roller for easy storage. Even with the flexible circuit board wrapped around the roller, the camera can still take pictures; users can adjust the setup according to their needs.

[0052] The rotating roller 1 is capable of elastic rotation, allowing the flexible circuit board 3 to retract elastically around it. After use, the rotating roller can elastically rotate in the retraction direction of the flexible circuit board, causing it to automatically retract around the roller for storage.

[0053] Specifically, the rotating roller 1 includes a central shaft 11, a mounting base 12, and an elastic element 13. The mounting base 12 is fixed inside the housing 4, and the elastic element 13 allows the central shaft 11 to be rotatably mounted on the mounting base 12. The second end of the flexible circuit board 3 is connected to the central shaft 11.

[0054] Furthermore, the elastic element 13 is a spring-loaded spring, so a receiving cavity 111 is provided at the center of the central shaft 11. The spring-loaded spring is disposed within the receiving cavity 111, with its first end connected to the side wall of the receiving cavity 111 and its second end connected to the mounting base 12. When the user pulls the camera or flexible circuit board to extend the camera, the central shaft rotates in the extension direction, thereby causing the first end of the spring-loaded spring to rotate and elastically compress the spring. After use, the spring-loaded spring elastically returns to its original position, and the central shaft elastically rotates in the retraction direction to achieve the storage of the flexible circuit board.

[0055] Furthermore, the mounting base 12 is provided with an insertion rod 121, which is inserted into the receiving cavity 111 and connected to the second end of the spring. The insertion rod has a clamping groove 122 at its end, into which the second end of the spring is inserted to achieve connection.

[0056] The camera device also includes a locking device 5. When the flexible circuit board 3 is extended into place, the locking device 5 is used to lock the rotating roller 1 in the elastic retraction direction. When the locking device 5 is released, the rotating roller 1 drives the flexible circuit board 3 to retract elastically. It is convenient to use and has a reasonable design.

[0057] Reference Figures 6 to 12 In the first structure of the locking device, a first mounting bracket 41 is provided inside the housing 4. The locking device 5 includes a ratchet 51 disposed on the rotating roller 1 and a check pawl 52 disposed on the first mounting bracket 41. When the check pawl 52 is inserted into the ratchet tooth 53 of the ratchet 51, the check pawl 52 locks the rotating roller 1 in the elastic retraction direction. When the check pawl 52 disengages from the ratchet tooth 53, the lock is released, and the rotating roller 1 can drive the flexible circuit board 3 to retract elastically. The ratchet can be connected to the central shaft of the rotating roller, and the mounting base of the rotating roller can be fixed on the first mounting bracket.

[0058] Specifically, the locking device 5 further includes a push rod 54 and a torsion spring 55. The push rod 54 is mounted on the first mounting bracket 41 and connected to the anti-return pawl 52. The first mounting bracket 41 is provided with a mounting shaft 42 and a column 43. The torsion spring 55 is sleeved on the mounting shaft 42, with its first end connected to the push rod 54 and its second end connected to the column 43. When the user pulls the camera or flexible circuit board, the presence of the ratchet will not affect the extension of the flexible circuit board. After the flexible circuit board has extended, under the action of the torsion spring, the anti-return pawl on the push rod will insert into the ratchet teeth of the ratchet to lock the rotating roller and prevent the flexible circuit board from elastically retracting. Furthermore, when the flexible circuit board needs to elastically retract, the user can operate the push rod to push the anti-return pawl out of the ratchet teeth to release the lock, allowing the rotating roller to drive the flexible circuit board to elastically retract. The operation is simple and convenient.

[0059] Reference Figures 13 to 20In a second configuration of the locking device, a second mounting bracket 44 is provided within the housing 4. The locking device 5 includes a mounting plate 56 disposed on the rotating roller 1 and a swing arm 57 disposed on the second mounting bracket 44. A locking guide rail 58 is provided on the mounting plate 56, and a locking block 571 is provided on the swing arm 57. The locking block 571 is inserted into the locking guide rail 58 so that the locking block 571 can lock the rotating roller 1 in the elastic retraction direction. The mounting plate can be connected to the central shaft of the rotating roller, and the mounting seat of the rotating roller can be fixed on the second mounting bracket.

[0060] Specifically, the locking guide rail 58 includes an outer extending guide rail 581 and an inner retractable guide rail 582. The locking block 571 is placed inside the retractable guide rail 582. A communication port 583 is provided between the extending guide rail 581 and the retractable guide rail 582. A guide block 584 is provided in the communication port 583. A first guide portion 585 is provided at the front end of the guide block. The first guide portion 585 is used to guide the locking block 571 in the retractable guide rail 582 into the extending guide rail 581. A locking groove 586 is provided at the rear end of the guide block 584. The locking groove 586 has a second guide portion 587 and a third guide portion 588. The second guide portion 587 is used to guide the locking block 571 in the extending guide rail 581 into the locking groove 586. The third guide portion 588 is used to guide the locking block 571 in the locking groove 586 into the retractable guide rail 582.

[0061] When in use, refer to the following when the user pulls the camera or flexible circuit board: Figure 16 The rotating roller (mounting plate) rotates in the extending direction, causing relative movement between the retractable guide rail and the locking block. When the locking block is positioned at the connection opening, because the rotating roller is rotating and the locking block is oscillating, the locking block falls into the extending guide rail under the action of the first guide. Furthermore, as the flexible circuit board continues to extend, the extending guide rail moves relative to the locking block accordingly. (Refer to...) Figure 17 When the user stops pulling, the rotating roller can elastically rotate in the retraction direction. At this time, the rotating roller will rotate slightly in the retraction direction, causing the flexible circuit board to partially retract elastically. This positions the locking block at the connection opening in the retraction direction, and under the action of the second guide, guides the locking block in the extension guide rail into the locking groove, thereby locking the rotating roller. (Refer to...) Figure 18 When the flexible circuit board needs to retract, the user stretches it slightly, causing the rotating roller to rotate slightly in the extension direction. Under the action of the third guide, the locking block in the locking groove is guided into the retraction guide rail, disengaging the locking block from the locking groove and thus releasing the lock. (See reference...) Figure 19As the rotating roller elastically rotates in the retraction direction, the flexible circuit board continues to retract, and the retraction guide rail moves relative to the locking block accordingly. (Refer to...) Figure 20 After retraction is complete, the locking block remains within the retraction guide rail.

[0062] Furthermore, the second mounting bracket 44 is provided with a limiting groove 45, and the swing arm 57 is disposed in the limiting groove 45 to limit the swing stroke of the swing arm 57. The locking block 571 protrudes from the limiting groove 45. The structure is simple and easy to assemble.

[0063] In the camera device, the camera 2 is mounted outside the housing 4. The flexible circuit board 3 includes an upper flexible circuit board 31 and a lower flexible circuit board 32 stacked together. The first end of the upper flexible circuit board 31 forms a data connection terminal 23, and the second end of the upper flexible circuit board 31 is connected to the second end of the lower flexible circuit board 32. The first end of the lower flexible circuit board 32 extends through the housing 4 and connects to the camera 2. In use, as the rotating roller rotates in the extension direction, the lower flexible circuit board extends outward along with the camera, while the upper flexible circuit board remains inside the housing to serve as the data connection terminal. When the rotating roller rotates in the retraction direction, the upper and lower flexible circuit boards retract synchronously. The upper and lower flexible circuit boards are stacked one on top of the other around the rotating roller, a reasonable and ingenious design.

[0064] The second end of the upper flexible circuit board 31 is integrally formed with the second end of the lower flexible circuit board 32.

[0065] Furthermore, the rotating roller 1 is provided with a connecting rod 14, and the bend 24 of the second end of the upper flexible circuit board 31 and the second end of the lower flexible circuit board 32 is sleeved on the connecting rod 14. The bend may have a sleeve hole through which the connecting rod is sleeved.

[0066] The housing 4 is provided with an opening 43, through which the first end of the lower flexible circuit board 32 passes through the opening 43 and exits the housing 4.

[0067] Furthermore, a slot 46 is provided on the outer side of the housing 4 corresponding to the opening 43, and the camera 2 is fitted into the slot 46.

[0068] Furthermore, the lens of the camera 2 is positioned facing the housing 4, requiring the camera to be flipped out of its slot for shooting. Alternatively, the lens of the camera 2 is positioned with its back to the housing 4, allowing for direct shooting.

[0069] The housing 4 houses a main circuit board 5, and the data connection terminal 23 of the upper flexible circuit board 31 is connected to the main circuit board 6. A battery 7 is also housed within the housing for power supply. The main circuit board has a charging interface 61 for charging the battery and a memory card slot 62 for holding a memory card. Operation buttons 8 are also provided on the housing.

[0070] The above descriptions provide one or more embodiments in conjunction with specific details, but do not imply that the specific implementation of this utility model is limited to these descriptions. Any methods or structures that are similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
