For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] First see Figures 1 to 3 The utility model provides a camera 10 with a telescopic lens barrel, wherein the lens barrel of the camera 10 can be spirally telescoped, such as Figure 1 to Figure 2 , making the camera 10 look more advanced when shooting, meeting people's psychological needs. Specifically, the camera 10 includes a main body 100, a lens barrel assembly 200 and a driving assembly 300. The main body 100 includes a shell 110, a circuit board 120 and a lens 130. The interior of the shell 110 is enclosed to form an installation cavity 111. The circuit board 120 is fixed in the installation cavity 111. The lens 130 is electrically connected to the circuit board 120. The lens barrel assembly 200 includes a fixed cylinder 210 and a telescopic cylinder 220. The fixed cylinder 210 is fixed relative to the shell 110. The telescopic cylinder 220 is movably arranged inside the fixed cylinder 210. The inner side wall of the fixed cylinder 210 is provided with a circumferentially spirally extending slide rail 211. The telescopic cylinder 220 is correspondingly provided with a slider 221. The slider 221 is movably arranged in the slide rail 211. The driving assembly 300 includes a driving motor 310 and The photoelectric sensor 330 and the drive motor 310 are fixed in the installation cavity 111 and electrically connected to the circuit board 120. The drive motor 310 drives the telescopic cylinder 220 to rotate around its axis, so that the slider 221 slides along the slide rail 211, so that the telescopic cylinder 220 can be spirally rotated and telescoped relative to the fixed cylinder 210. The photoelectric sensor 330 is electrically connected to the circuit board 120. The photoelectric sensors 330 are respectively arranged at both ends of the slide rail 211. When the slider 221 slides to the end of the slide rail 211 and abuts against the photoelectric sensor 330, the photoelectric sensor 330 is triggered to control the drive motor 310 to stop rotating, thereby avoiding the drive motor 310 and the telescopic cylinder 220 from continuing to rotate when the telescopic cylinder 220 reaches the extension limit, thereby preventing the drive motor 310 and the telescopic cylinder 220 from being damaged.

[0035] refer to Figure 3 The main body 100 also includes a battery 140 and a flexible conductive member 150. The battery 140 is fixed inside the installation cavity 111. The battery 140 is electrically connected to the circuit board 120. The battery 140 can supply power to the drive motor 310. The lens 130 is fixed to the end of the telescopic tube 220 away from the shell 110 and moves with the telescopic tube 220. One end of the flexible conductive member 150 is connected to the circuit board 120, and the other end is connected to the lens 130. The shooting data of the lens 130 is transmitted to the circuit board 120 through the flexible conductive member 150. When the lens 130 is extended and retracted with the telescopic tube 220, the flexible conductive member 150 can be folded or stretched.

[0036] Continue to refer Figure 3The driving assembly 300 also includes a driving gear 320. The inner wall of the fixed cylinder 210 is recessed to form a driving groove 212.

When the driving motor 310 is turned on, the driving motor 310 can drive the driving gear 320 to rotate. The outer peripheral wall of the telescopic cylinder 220 is provided with a plurality of tooth grooves 222 extending circumferentially. The driving gear 320 can be inserted into the tooth grooves 222. When the driving gear 320 rotates, the driving gear 320 can be inserted into different tooth grooves 222 along the circumferential direction, thereby driving the telescopic cylinder 220 to rotate circumferentially.

[0037] The driving gear 320 has a cylindrical structure, and the axis of the driving gear 320 is parallel to the axis of the fixed cylinder 210. The driving motor 310 drives the driving gear 320 to rotate around its axis. The driving gear 320 extends from one end of the fixed cylinder 210 to the other end along the axis direction of the fixed cylinder 210. When the telescopic cylinder 220 spirally rotates and telescopes and causes the tooth groove 222 to move up and down synchronously, the driving gear 320 can always be stuck in the tooth groove 222. It can be understood that in other embodiments, the driving gear 320 can also be set to a sheet-like structure. At this time, the tooth groove 222 extends from one end to the other end along the outer wall of the telescopic cylinder 220 relative to each other, so that the driving gear 320 is always stuck in the tooth groove 222.

[0038] refer to Figures 4 to 6 The lens barrel assembly 200 also includes a protective tube 230, which is sleeved on the outside of the fixed tube 210 to protect the fixed tube 210 and the telescopic tube 220 from being damaged. The telescopic tube 220 includes a first telescopic tube 223, a second telescopic tube 224 and a third telescopic tube 225 which are arranged in sequence from the outside to the inside. The first telescopic tube 223 is sleeved on the outside of the second telescopic tube 224, and the second telescopic tube 224 is sleeved on the outside of the third telescopic tube 225. The tooth groove 222 is arranged on the outer peripheral wall of the first telescopic tube 223. The driving motor 310 drives the driving gear 320 to rotate, and the driving gear 320 drives the first telescopic tube 223 to rotate circumferentially. The first telescopic tube 223 spirally rotates and telescopes relative to the fixed tube 210 and can be decomposed into a vertical direction along the axial direction. The first telescopic cylinder 223 and the second telescopic cylinder 224 are limited in the axial direction of the first telescopic cylinder 223, that is, when the first telescopic cylinder 223 is spirally telescoped, the second telescopic cylinder 224 moves vertically with the first telescopic cylinder 223, and the second telescopic cylinder 224 and the first telescopic cylinder 223 can move relative to each other in the circumferential rotation direction; the third telescopic cylinder 225 and the second telescopic cylinder 224 are limited in the circumferential rotation direction, that is, the third telescopic cylinder 225 and the second telescopic cylinder 224 cannot move relative to each other in the circumferential rotation direction, and the third telescopic cylinder 225 and the second telescopic cylinder 224 can move relative to each other in the axial direction; the first telescopic cylinder 223 and the third telescopic cylinder 225 are relatively movable in both the vertical and circumferential directions.

[0039] The first telescopic cylinder 223 and the second telescopic cylinder 224 are limited in the axial direction, the outer peripheral wall of the second telescopic cylinder 224 is provided with a circumferentially surrounding card slot 2241, the inner side wall of the first telescopic cylinder 223 is provided with a corresponding card block 2231, the card block 2231 is accommodated in the card slot 2241, and when the first telescopic cylinder 223 rotates, the card block 2231 slides along the card slot 2241, so that the second telescopic cylinder 224 and the first telescopic cylinder 223 move relative to each other in the circumferential rotation direction, and the groove walls on the upper and lower sides of the card slot 2241 block the card block 2231. The block 2231 moves up and down to limit the second telescopic cylinder 224 and the first telescopic cylinder 223 in the axial direction. A plurality of blocks 2231 are arranged at intervals along the inner wall of the first telescopic cylinder 223, and the plurality of blocks 2231 are all inserted into the slot 2241. It should be noted that the block 2231 can also be arranged on the outer wall of the second telescopic cylinder 224, and the slot 2241 can also be correspondingly arranged on the inner wall of the first telescopic cylinder 223, as long as the first telescopic cylinder 223 and the second telescopic cylinder 224 are limited in the axial direction.

[0040] The slide rail 211 includes a first rail 2111 and a second rail 2112. The first rail 2111 spirally extends from one end to the other end along the inner wall of the fixed cylinder 210. The second rail 2112 is also arranged on the inner wall of the fixed cylinder 210 and extends along the axial direction. The slider 221 includes a first protrusion 2211 and a second protrusion 2212. The first protrusion 2211 is arranged on the outer wall of the first telescopic cylinder 223. The second protrusion 2212 is arranged on the outer wall of the second telescopic cylinder 224 close to one end of the housing 110, and the second protrusion 2212 can extend from the first telescopic cylinder 223. The first protrusion 2211 is located in the first rail 2111 and can slide along the first rail 2111. The second protrusion 2212 12 is located on the second track 2112 and can slide along the second track 2112. When the driving motor 310 drives the driving gear 320 to rotate to drive the first telescopic cylinder 223 to rotate, the first protrusion 2211 slides along the first track 2111 synchronously. Since the first track 2111 extends in a spiral shape, the first telescopic cylinder 223 rotates circumferentially and moves along the axial direction at the same time. The first telescopic cylinder 223 drives the second telescopic cylinder 224 to move along the axial direction, and the second protrusion 2212 slides along the second track 2112. The groove walls on both sides of the second track 2112 can prevent the second telescopic cylinder 224 from rotating circumferentially, so that the second telescopic cylinder 224 can only move along the axial direction relative to the fixed cylinder 210.

[0041] The second telescopic cylinder 224 is also provided with a sliding hole 2242, which extends from one end to the other end along the axial direction of the second telescopic cylinder 224. The inner wall of the first telescopic cylinder 223 is also provided with a third track 2232 extending in a circumferential spiral direction. The outer side wall of the third telescopic cylinder 225 is correspondingly provided with a third protrusion 2251, which passes through the sliding hole 2242 and is stuck in the third track 2232. When the first telescopic cylinder 223 rotates, the side wall of the third track 2232 pushes the third protrusion 2251 to rotate. 251 moves so that the third protrusion 2251 slides along the third track 2232, and at the same time, the hole wall of the sliding hole 2242 blocks the third protrusion 2251 from moving in the circumferential direction, so that the third protrusion 2251 can only move in the vertical direction, and the third telescopic cylinder 225 is telescopic relative to the first telescopic cylinder 223 along the axial direction; when the driving motor 310 drives the first telescopic cylinder 223 to rotate, the first protrusion 2211 slides along the first track 2111, so that the first telescopic cylinder 223 is spirally extended relative to the fixed cylinder 210, and the third telescopic cylinder 225 is telescopic relative to the first telescopic cylinder 223. The first telescopic cylinder 223 simultaneously drives the second telescopic cylinder 224 to extend relative to the fixed cylinder 210 along the axial direction, and the second protrusion 2212 slides along the second track 2112. At the same time, the side wall of the third track 2232 provided on the first telescopic cylinder 223 pushes the third protrusion 2251 to slide relatively, and the third protrusion 2251 also slides along the sliding hole 2242, so that the third telescopic cylinder 225 extends relative to the first telescopic cylinder 223 along the axial direction. When the first protrusion 2211 slides to the end of the first track 2111, the third protrusion 2251 is moved relative to the first telescopic cylinder 223. The first telescopic tube 223, the second telescopic tube 224 and the third telescopic tube 225 all reach the extension limit, the first protrusion 2211 abuts against the photoelectric sensor 330, and the photoelectric sensor 330 controls the drive motor 310 to stop rotating. Similarly, when the first telescopic tube 223, the second telescopic tube 224 and the third telescopic tube 225 all reach the retraction limit, the second protrusion 2212 slides to the end of the second track 2112 and abuts against the photoelectric sensor 330, and the photoelectric sensor 330 controls the drive motor 310 to stop rotating.

[0042] The first track 2111 extends circumferentially at a portion of the end of the fixed tube 210 facing away from the shell 110, so that the first telescopic tube 223 can continue to rotate circumferentially when reaching the limit of the extension direction. The third track 2232 extends circumferentially and undulates at a portion of the end of the first telescopic tube 223 facing away from the shell 110. When the first telescopic tube 223 reaches the limit of extension, the first protrusion 2211 continues to rotate circumferentially along the first track 2111, and the first telescopic tube 223 continues to rotate circumferentially relative to the fixed tube 210. At the same time, the side wall of the third track 2232 pushes the third protrusion 2251 to move back and forth in the vertical direction, so that the third telescopic tube 225 can be extended and retracted back and forth along the axial direction relative to the first telescopic tube 223, so that the camera 10 gives a high-level zoom feeling when in use.

[0043] A plurality of first rails 2111, a plurality of second rails 2112 and a plurality of third rails 2232 are respectively provided, and a plurality of first rails 2111 are arranged at intervals along the circumferential direction of the inner wall of the fixed cylinder 210, a plurality of second rails 2112 are arranged at intervals along the circumferential direction of the inner wall of the fixed cylinder 210, a plurality of third rails 2232 are arranged at intervals along the circumferential direction of the inner wall of the first telescopic cylinder 223, and a plurality of first protrusions 2211, a second protrusion 2212 and a third protrusion 2251 are also respectively provided, and the first protrusion 2211, the second protrusion 2212 and the third protrusion 2251 slide along the first rail 2111, the second rail 2112 and the third rail 2232 respectively, so that the first telescopic cylinder 223, the second telescopic cylinder 224 and the third telescopic cylinder 225 are more stable when telescoping.

[0044] The photoelectric sensor 330 includes a conductive sheet 331, a first contact block 332 and a second contact block 333. The first contact block 332 is disposed at the end of the first track 2111, and the second contact block 333 is disposed at the end of the second track 2112. The first contact block 332 and the second contact block 333 are respectively located at two ends of the fixed cylinder 210. The first contact block 332 and the second contact block 333 are respectively electrically connected to the conductive sheet 331. The other end of the conductive sheet 331 is electrically connected to the circuit board 120. When the first telescopic cylinder 223 is extended, the first protrusion 2211 first spirally slides along the first track 2111. When the first protrusion 2211 reaches the end of the fixed cylinder 210, the first The protrusion 2211 continues to slide circumferentially along the first track 2111 until the first protrusion 2211 slides to the end of the first track 2111 and abuts against the first contact block 332, the drive motor 310 stops rotating, and the first telescopic cylinder 223 stops rotating. When retracted, the second protrusion 2212 slides along the second track 2112 and slides to the end of the second track 2112, the second protrusion 2212 abuts against the second contact block 333, the drive motor 310 stops rotating, and the first telescopic cylinder 223 stops rotating.
