[0029] 1 to 5, the imaging device includes a rotating roller 1, a camera 2, a flexible circuit board 3, and a case 4, the rotating roller 1 is installed in the case 4, the flexible circuit board 3 is installed in an elongated shape, a first end of the flexible circuit board 3 is connected to the camera 2, a second end of the flexible circuit board 3 is connected to the rotating roller 1, and the flexible circuit board 3 is installed around the rotating roller 1, so that the camera 2 can be flexibly extended by the flexible circuit board 3.

[0030] With the above-described structure, when in use, the camera or the flexible circuit board is pulled, causing the rotating roller to rotate in the extension direction, and the camera is flexibly extended by the flexible circuit board. When taking a picture, the case can be left in the desired position, making it more flexible and easy to use. The flexible extension of the camera makes it applicable to a wider range of usage scenarios, particularly for covert photography in special scenes. For example, the case can be left in a mobile phone bag, and the flexible extension of the flexible circuit board allows the camera to extend to the opening of the bag, making it easier to take pictures. The case can also be left in a clothes pocket, and the flexible extension of the flexible circuit board allows the camera to extend to the opening of the pocket, making it easier to take pictures. Of course, users can leave it as needed for the desired usage scenario, and we will not list the various usage scenarios one by one here.

[0031] After use, the flexible circuit board rotates around the rotating roller again, allowing the flexible circuit board to be stored and easily used. Of course, the camera can also take pictures while the flexible circuit board is rotating around the rotating roller, so users can adjust it according to the required usage scenario.

[0032] Here, the rotating roller 1 is an elastically rotatable rotating roller, so that the flexible circuit board 3 can elastically contract around the rotating roller 1. After use, the rotating roller can elastically rotate in the contraction direction of the flexible circuit board, and the flexible circuit board automatically rotates around the rotating roller to store the flexible circuit board.

[0033] Specifically, the rotating roller 1 includes a central shaft 11, a mounting base 12, and an elastic member 13, the mounting base 12 is fixed within the case 4, the central shaft 11 is elastically rotatably mounted on the mounting base 12 by the elastic member 13, and the second end of the flexible circuit board 3 is connected to the central shaft 11.

[0034] Furthermore, since the elastic member 13 is a spiral spring, an accommodating cavity 111 is installed at the center of the central shaft 11, the spiral spring is installed in the accommodating cavity 111, a first end of the spiral spring is connected to the side wall of the accommodating cavity 111, and a second end of the spiral spring is connected to the mounting base 12. When a user pulls the camera or the flexible circuit board to extend the camera, the central shaft rotates in the extension direction, thereby rotating the first end of the spiral spring and elastically compressing the spiral spring. After use, the spiral spring elastically returns to its original position, and the central shaft elastically rotates in the contraction direction to accommodate the flexible circuit board.

[0035] Furthermore, an insertion rod 121 is installed on the mounting base 12, and the insertion rod 121 is inserted into the receiving cavity 111 and connected to the second end of the spiral spring. Here, a clamping groove 122 is opened at the end of the insertion rod, and the second end of the spiral spring is placed in the clamping groove to achieve connection.

[0036] The imaging device further includes a locking device 5, which is used to lock the rotating roller 1 in an elastic contraction direction when the flexible circuit board 3 is extended to a predetermined position, and when the locking device 5 is released, the rotating roller 1 moves the flexible circuit board 3 to elastically contract, making it easy to use and rational in design.

[0037] 6 to 12, in a first type of locking device structure, a first mounting frame 41 is installed in the case 4, and the locking device 5 includes a ratchet 51 installed on the rotating roller 1 and a pawl 52 installed on the first mounting frame 41. When the pawl 52 is inserted into the ratchet teeth 53 of the ratchet 51, the pawl 52 locks the rotating roller 1 in an elastic contraction direction. When the pawl 52 is released from the ratchet teeth 53, that is, the lock is released, and the rotating roller 1 can move the flexible circuit board 3 to elastically contract. Here, the ratchet may be connected to the central axis 11 of the rotating roller 1, and the mounting base 12 of the rotating roller 1 may be fixed on the first mounting frame 41.

[0038] Specifically, the locking device 5 further includes a push rod 54 and a torsion spring 55. The push rod 54 is installed on the first mounting frame 41 and connected to the locking claw 52. A mounting shaft 42 and a pillar 43 are installed on the first mounting frame 41. The torsion spring 55 is fitted onto the mounting shaft 42, with a first end of the torsion spring 55 connected to the push rod 54 and a second end of the torsion spring 55 connected to the pillar 43. When a user pulls the camera or the flexible circuit board, the presence of the ratchet does not affect the extension of the flexible circuit board. After the flexible circuit board has finished extending, the torsion spring acts to insert the locking claw of the push rod into the ratchet teeth of the ratchet, locking it against the rotating roller and preventing the flexible circuit board from elastically contracting. When the flexible circuit board needs to be elastically contracted, the user can operate the push rod to push the locking pawl so that it is detached from the ratchet teeth, thereby releasing the lock, and the rotating roller moves the flexible circuit board so that it elastically contracts, making the operation simple and easy to use.

[0039] 13 to 20, in a second structure of the locking device, a second mounting frame 44 is installed in the case 4, and the locking device 5 includes a mounting plate 56 installed on the rotating roller 1 and a swing arm 57 installed on the second mounting frame 44. A lock guide rail 58 is installed on the mounting plate 56, and a lock block 571 is installed on the swing arm 57, and the lock block 571 is located within the lock guide rail 58, so that the lock block 571 can lock the rotating roller 1 in the elastic contraction direction. Here, the mounting plate may be connected to the central axis of the rotating roller, and the mounting base of the rotating roller may be fixed on the second mounting frame.

[0040] Specifically, the lock guide rail 58 includes an outer ring extending guide rail 581 and an inner ring retracting guide rail 582, the lock block 571 is placed in the retracting guide rail 582, a communication port 583 is provided between the extending guide rail 581 and the retracting 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, and the first guide portion 585 is connected to the lock block 57 in the retracting guide rail 582. 1 into the extending guide rail 581, and a locking groove 586 is provided at the rear end of the guide block 584, and 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, and the third guide portion 588 is used to guide the locking block 571 in the locking groove 586 to the retracting guide rail 582.

[0041] When the user pulls the camera or flexible circuit board, as shown in FIG. 16, the rotating roller (mounting plate) rotates in the extension direction, and the retracting guide rail moves relative to the locking block. When the locking block is positioned at the corresponding opening, the rotating roller rotates and the locking block swings, causing the locking block to fall into the extension guide rail under the action of the first guide portion. As the flexible circuit board continues to extend, the extension guide rail moves relative to the locking block accordingly. As shown in FIG. 17, when the user finishes pulling, the rotating roller can elastically rotate in the retracting direction, causing the rotating roller to rotate slightly in the retracting direction, i.e., to move the flexible circuit board to partially retract elastically. The locking block is positioned at the corresponding opening in the retracting direction, and the second guide portion guides the locking block on the extension guide rail into the locking groove to lock the rotating roller.

[0004] Referring to Fig. 18, when the flexible circuit board needs to be shrunk, the user pulls the flexible circuit board slightly, i.e., the rotating roller rotates slightly in the extension direction, and the third guide part guides the locking block in the locking groove into the shrinking guide rail, and the locking block disengages from the locking groove, thereby unlocking. Referring to Fig. 19, the flexible circuit board elastically rotates in the shrinking direction along with the rotating roller, and the shrinking guide rail moves relative to the locking block accordingly. Referring to Fig. 20, after the flexible circuit board has shrunk, the locking block remains positioned within the shrinking guide rail.

[0042] Furthermore, a stopper groove 45 is installed on the second mounting frame 44, the swing arm 57 is installed in the stopper groove 45 and is used to limit the swing stroke of the swing arm 57, and the lock block 571 is installed protruding from the stopper groove 45, which has a simple structure and is easy to assemble.

[0043] In the imaging device, the camera 2 is installed outside the case 4, and the flexible circuit board 3 includes an upper flexible circuit board 21 and a lower flexible circuit board 22 stacked one on top of the other.

When in use, the camera rotates in the extension direction along with the rotating roller, and the lower flexible circuit board extends outward along with the camera. The upper flexible circuit board remains within the case throughout and serves as the data connection end. When the rotating roller rotates in the contraction direction, the upper and lower flexible circuit boards contract synchronously, and the upper and lower flexible circuit boards wrap around the rotating roller in a stacked manner, resulting in a rational and ingenious design.

[0044] Here, the second end of the upper flexible circuit board 21 is integrally formed with the second end of the lower flexible circuit board 22 .

[0045] Furthermore, a connecting rod 14 is installed on the rotating roller 1, and the bent portions 24 of the second ends of the upper flexible circuit board 21 and the lower flexible circuit board 22 are fitted onto the connecting rod 14. Here, fitting holes may be formed in the bent portions, and the connecting rods are fitted onto the bent portions through the fitting holes.

[0046] Here, an opening 43' is formed in the case 4, and a first end of the lower flexible circuit board 22 passes through the case 4 through the opening 43'.

[0047] Furthermore, a locking groove 46 is provided on the outside of the case 4 at a position corresponding to the opening 43', and the camera 2 is installed by being locked in the locking groove 46.

[0048] Furthermore, the lens of the camera 2 is installed facing the case 4, and the camera needs to be removed from the locking groove when taking a picture, or the lens of the camera 2 is installed facing away from the case 4, and the camera can be taken directly when taking a picture.

[0049] Here, a main circuit board 6 is installed in the case 4, and the data connection end 23 of the upper flexible circuit board 21 is connected to the main circuit board 6. A battery 7 for supplying power is also installed in the case.
