The embodiment of the utility model provides a lens assembly, which can be applied to image pickup equipment. The lens component can be deformed in a telescopic way, can be stretched when in use, and can be contracted when in storage, so that the occupation of space is reduced.

Referring to fig. 1, the lens assembly includes a fixing module 10 and a lens module 20.

The fixing module 10 includes a fixing base 11 and a bump 12, the fixing base 11 is formed with a mounting hole 101, and the bump 12 protrudes from an inner wall of the mounting hole 101. The cross section of the mounting hole 101 is circular, and the axis of the mounting hole 101 may be the central axis of the fixing seat 11.

The lens module 20 includes a lens barrel 21 movably sleeved in the mounting hole 101, and a sidewall of the lens barrel 21 is attached to an inner wall of the mounting hole 101. The lens barrel 21 is slidable in the mounting hole 101 along the axis of the mounting hole 101 with respect to the fixed base 11, and is rotatable in the mounting hole 101 about the axis thereof with respect to the fixed base 11. The side wall of the lens barrel 21 is provided with a telescopic groove 201 and a rotating groove 202, the telescopic groove 201 extends along the axial direction of the lens barrel 21, the rotating groove 202 extends along the circumferential direction of the lens barrel 21 and is communicated with the telescopic groove 201, and the telescopic groove 201 and the rotating groove 202 jointly form an L shape, a T shape or a cross shape.

Referring to fig. 2 and 3, the projection 12 can extend into the expansion slot 201 and also into the rotation slot 202. When the bump 12 extends into the telescopic slot 201, the lens barrel 21 can slide between the shooting position and the storage position, at this time, the bump 12 slides in the telescopic slot 201 along the extending direction of the telescopic slot 201, and when the lens barrel 21 slides to the shooting position, the bump 12 is located in the extending direction of the rotating slot 202, at this time, the lens barrel 21 can rotate, so that the bump 12 slides into the rotating slot 202. The protrusions 12 may abut against the bottom of the telescopic groove 201 or the bottom of the rotating groove 202, may be spaced apart, and the protrusions 12 may be attached to the side walls of the telescopic groove 201 and the side walls of the rotating groove 202, or may be spaced apart.

When the bump 12 is located in the telescopic slot 201, the user can operate the lens barrel 21 to extend and retract. When the user pulls out the lens barrel 21 to the position where the projection 12 is located in the telescopic slot 201 and is opposite to the rotating slot 202, the user can operate the lens barrel 21 to rotate, and the slot wall of the rotating slot 202 can limit the axial movement of the projection 12, so that the fixing module 10 limits the axial movement of the lens barrel 21 through the projection 12, and the user can operate the lens assembly normally. When the user rotates the lens barrel 21 to the projection 12 from the rotation groove 202 to the telescopic groove 201, the user can press the lens barrel 21 to retract the lens barrel 21 toward the fixing base 11, so as to reduce the occupied space of the lens assembly and facilitate the storage of the lens assembly.

Specifically, referring to fig. 1 to 3, the lens barrel 21 is cylindrical and extends along the axial direction of the mounting hole 101, the lens barrel 21 has a photographing end and a connecting end in the extending direction thereof, the connecting end is located in the mounting hole 101, the photographing end is located outside the mounting hole 101, the extending direction of the telescopic slot 201 is in the same direction as the extending direction of the lens barrel 21, the telescopic slot 201 has a first position and a second position in the extending direction thereof, the first position is close to the photographing end of the lens barrel 21, the second position is close to the connecting end of the lens barrel 21, and the second position is located in the extending direction of the rotating slot 202, i.e. the second position is located at the intersection of the rotating slot 202 and the telescopic slot 201. The bump 12 can extend into the telescopic slot 201, and at this time, the bump 12 can move between the first position and the second position, and accordingly, the lens barrel 21 slides between the shooting position and the storage position. When the bump 12 moves in the telescopic slot 201, the two side slot walls of the telescopic slot 201 can limit the bump 12 to move around the circumference of the lens barrel 21, and accordingly, the fixed module 10 limits the rotation of the lens module 20 through the bump 12. When the bump 12 is located at the first position, the lens barrel 21 moves to the storage position, and the lens assembly is shortened at this time, so that the lens assembly is stored. When the bump 12 is at the second position, the lens barrel 21 is at the shooting position, the lens assembly is elongated, the bump 12 faces the rotating groove 202, the lens barrel 21 is rotated, the bump 12 can be rotated into the rotating groove 202, the two side groove walls of the rotating groove 202 can limit the bump 12 to axially move, and correspondingly, the fixed module 10 also limits the axial movement of the lens module 20 through the bump, so that a user can normally operate the lens assembly.

In one embodiment, referring to fig. 1, the bump 12 can be slidably connected to the telescopic slot 201 and the rotating slot 202, so as to improve the stability of the lens barrel 21 during sliding and limit the lens barrel 21 from shaking during the telescopic process. Wherein, the length of the bump 12 in the axial direction of the lens barrel 21 is adapted to the width of the rotation groove 202 to slide in the rotation groove 202 along the extending direction of the rotation groove 202, and the width of the bump 12 in the circumferential direction of the lens barrel 21 is adapted to the width of the telescopic groove 201 to slide in the telescopic groove 201 along the extending direction of the telescopic groove 201. The width of the rotation groove 202 is the width of the rotation groove 202 perpendicular to the extending direction thereof, and the width of the expansion groove 201 is the width of the expansion groove 201 perpendicular to the extending direction thereof.

In one embodiment, the fixing module 10 further includes a first limiting structure disposed on the inner wall of the mounting hole 101, and the lens module 20 further includes a second limiting structure disposed on the side wall of the lens barrel 21, and when the lens barrel 21 moves to the shooting position, the first limiting structure limits the second limiting structure to move along the axial direction of the lens barrel 21. It can be appreciated that when the user pulls out the lens barrel 21 to the photographing position, the lens barrel 21 stops moving due to the limiting action of the first limiting structure on the second limiting structure, so that the lens barrel 21 stays at the photographing position to avoid the lens barrel 21 from being separated from the mounting hole 101. At this time, the bump 12 is located at the second position, i.e. the bump 12 faces the rotating groove 202, so that the user can rotate the lens barrel 21.

In one embodiment, referring to fig. 1 and 4, the second limiting structure includes a limiting edge 221 protruding from at least a side wall of the lens barrel 21, the limiting edge 221 extends around a circumference of the lens module 20, the first limiting structure includes a chute 131 disposed on an inner wall of the mounting hole 101, the chute 131 extends around the circumference of the lens module 20, a notch 132 is formed in a side wall of the chute 131, and the notch 132 can avoid the limiting edge 221 in an axial direction of the lens barrel 21. When the lens barrel 21 slides to the shooting position, the limiting edge 221 enters the chute 131 through the notch 132 and is slidably connected with the chute 131. When the lens barrel 21 slides to the shooting position, the limiting edge 221 abuts against the groove wall of the chute 131, which is opposite to the notch 132, and at this time, the groove wall limits the limiting edge 221 to move axially continuously, and when the user rotates the lens barrel 21, the limiting edge 221 can enter the chute 131 under the guidance of the groove wall of the chute 131 to be connected with the chute 131 in a sliding manner, and at this time, the protrusion slides into the rotating groove 202. Thus, the two side groove walls of the chute 131 can limit the axial movement of the limiting edge 221, so as to limit the axial movement of the lens barrel 21 in the rotating process.

The width of the chute 131 may be reduced along the extending direction thereof, so that the limiting edge 221 is gradually clamped by both side walls of the chute 131 during rotation, thereby limiting the rotation of the lens barrel 21 and preventing the lens barrel 21 from loosening.

Optionally, referring to fig. 4, the fixing module 10 may further include a third limiting structure 16, where the third limiting structure 16 can limit the limiting edge 221 to slide in the chute 131. When the lens barrel 21 is located at the shooting position and the user rotates the lens barrel 21, the limiting edge 221 may abut against or be connected to the third limiting structure 16, so that the lens barrel 21 is fixed at the fixed position. The third limiting structure 16 may be a protrusion or a clamping block protruding into the chute 131.

In one embodiment, referring to fig. 1, a plurality of limiting edges 221 are provided, and the plurality of limiting edges 221 are equally spaced around the circumference of the lens barrel 21. Correspondingly, the groove walls of the sliding grooves 131 are provided with a plurality of openings 132, and the number of the openings 132 is equal to that of the limiting edges 221 and the positions of the openings are opposite to each other so as to avoid the limiting edges 221. In the illustrated embodiment, the number of notches 132 and stop edges 221 is three.

In the illustrated embodiment, the extension ends of the telescopic slot 201 may be both closed, and the telescopic slot 201 and the rotating slot 202 together form a T-shape.

In one embodiment, referring to fig. 4, the fixing module 10 further includes an elastic member 14 connecting the bump 12 and the fixing base 11, and the elastic member 14 can apply an elastic force to the bump 12 toward the lens barrel 21, so that the bump 12 abuts against the lens barrel 21. The protrusion 12 can elastically abut against the groove bottom of the telescopic groove 201 or the groove bottom of the rotating groove 202 by the elastic force of the elastic member 14 to clamp the lens barrel 21 together with the wall of the mounting hole 101, thereby restricting the shake of the lens barrel 21 in the mounting hole 101. The elastic member 14 may be a spring, a rubber pad, an elastic cord, or the like.

In the illustrated embodiment, the elastic member 14 is a spring, and is located on a side of the bump 12 facing away from the lens barrel 21, the bump 12 may be sleeved on an end of the spring, and the spring is always in a compressed state to apply an elastic force to the bump 12 toward the lens barrel 21.

Alternatively, referring to fig. 4, the inner wall of the mounting hole 101 is provided with a mounting groove 102, the elastic member 14 is at least partially received in the mounting groove 102, and the protrusion 12 is partially received in the mounting groove 102 and is capable of sliding along the opening direction of the mounting groove 102. The mounting groove 102 has a positioning function on the elastic element 14 and the protruding block 12, so that the mounting is convenient, and meanwhile, the groove wall of the mounting groove 102 also limits the elastic element 14 from twisting in the elastic deformation process.

Optionally, referring to fig. 4, the fixing module 10 further includes a connecting seat 15, the fixing seat 11 includes an inner fixing portion 111 and an outer fixing portion 112 movably connected to each other, the inner fixing portion 111 is provided with the mounting hole 101, the outer fixing portion 112 is movably sleeved outside the inner moving portion, a mounting cavity is formed between the inner fixing portion 111 and the outer fixing portion 112, and the connecting seat 15 is accommodated in the mounting cavity. The mounting groove 102 is a through groove, the connecting seat 15 is provided with a connecting hole, the connecting hole is opposite to the mounting groove 102, and the elastic member 14 is partially accommodated in the connecting hole and partially accommodated in the mounting groove 102. The connecting seat 15, the elastic member 14 and the bump 12 can together form an independent structural member for easy production and installation.

In one embodiment, referring to fig. 4, one end of the bottom surface of the rotation groove 202 is connected to the bottom surface of the telescopic groove 201, and the other end is connected to the side wall surface of the lens barrel 21. That is, the depth of the rotation groove 202 gradually decreases along the direction facing away from the telescopic groove 201, so that when the lens barrel 21 rotates from the photographing position, the bump 12 can slide from the second position in the telescopic groove 201 to the rotation groove 202 and then slide out of the rotation groove 202 to the outer peripheral sidewall of the lens barrel 21, and at this time, the bump 12 presses the elastic member 14 under the pressing of the outer peripheral sidewall of the lens barrel 21, so as to increase the elastic force of the elastic member 14, thereby enhancing the clamping force of the bump 12 on the lens barrel 21, and further improving the stability of the lens barrel 21.
