As shown in FIGS. 1 to 5 , an embodiment of the present application provides a smart glasses, wherein the smart glasses include: a lens 61, a frame 62, and a zoom lens 1 disposed on the frame 62, wherein the lens 61 is disposed on the frame 62, and the lens 61 and the frame 62 form a glasses body 6. The zoom lens 1 is used for imaging, and is used for a user to adjust the focal length of the zoom lens 1.

The zoom lens 1 comprises a liquid lens 11, a zoom assembly 12 and a focusing module 2. The liquid lens 11 has a flexible curved surface 111 protruding along its axial direction. The liquid lens 11 is mounted on the zoom assembly 12, and a part of the zoom assembly 12 is in contact with the flexible curved surface 111. The focusing module 2 is in transmission connection with the zoom assembly 12. The focusing module 2 can drive the zoom assembly 12 to drive the liquid lens 11 to reciprocate along its axial direction, and the focusing module 2 can drive the zoom assembly 12 to squeeze the flexible curved surface 111, so that the flexible curved surface 111 is deformed along the axial direction of the liquid lens 11.

Optionally, as shown in FIG. 1 , the zoom lens 1 can be detachably hung on any side of the lens frame 62 .

Optionally, as shown in FIG. 2 , the zoom lens 1 is detachably embedded in a lens frame 62 and is located between two lenses 61 .

The smart glasses, zoom camera and electronic device of the embodiments of the present application adopt a liquid lens. The flexible surface of the liquid lens is squeezed by the zoom component to deform the flexible surface, which can change the curvature of the flexible surface. At the same time, the zoom component is set to drive the liquid lens to move back and forth along its radial direction to change the position of the liquid lens, thereby effectively realizing the zoom of the liquid lens, improving the effect of taking pictures and videos, and enhancing the user experience.

As shown in Figures 4 and 5, an embodiment of the present application also provides a zoom camera, which includes a liquid lens 11 and a zoom assembly 12. The liquid lens 11 has a flexible curved surface 111 protruding along its axial direction; the liquid lens 11 is installed in the zoom assembly 12, and a part of the zoom assembly 12 is in contact with the flexible curved surface 111; the zoom assembly 12 can drive the liquid lens 11 to reciprocate along its axial direction, and the zoom assembly 12 can squeeze the flexible curved surface 111 to cause the flexible curved surface 111 to deform along the axial direction of the liquid lens 11.

Optionally, the zoom camera further includes a focus module 2 , which is in transmission connection with the zoom assembly 12 , and the focus module 2 is used for allowing a user to adjust the zoom assembly 12 so as to adjust the focal length of the liquid lens 11 .

The liquid lens 11 is composed of a soft transparent film and a filling liquid, and is used to replace the lens of a traditional camera. When squeezed by an external force, the liquid lens 11 will undergo adaptive deformation, and the focal length will be changed by changing its surface curvature. Specifically, the liquid lens 11 has a flexible curved surface 111 convex along its axial direction. In order to ensure the controllability of the deformation of the liquid lens 11, during the imaging process, other parts of the liquid lens 11 keep their original shapes unchanged, and the focal length is adjusted only by the deformation of its flexible curved surface 111.

A through cavity is formed in the zoom assembly 12, and the liquid lens 11 is installed in the through cavity of the zoom assembly 12, and a part of the zoom assembly 12 is in contact with the flexible curved surface 111. By adjusting the zoom assembly 12, the force applied to the flexible curved surface 111 when the zoom assembly 12 is in contact with the flexible curved surface 111 can be changed to adjust the deformation degree of the flexible curved surface 111, thereby changing the curvature of the flexible curved surface 111;

The focus module 2 is connected to the zoom assembly 12 in a transmission manner. By operating the focus module 2, the focus module 2 can drive the zoom assembly 12 to adjust the focal length of the liquid lens 11.

Specifically, on the one hand, the focusing module 2 can drive the zoom assembly 12 to drive the liquid lens 11 to reciprocate along its axial direction. On the other hand, the focusing module 2 can drive the zoom assembly 12 to extrude the flexible curved surface 111, so that the flexible curved surface 111 is deformed along the axial direction of the liquid lens 11. The focal length of the liquid lens 11 is adjusted through the displacement and/or deformation of the liquid lens 11.

In the embodiment of the present application, a liquid lens 11 is adopted, and the flexible curved surface 111 of the liquid lens 11 is squeezed by the zoom component 12, so that the flexible curved surface 111 is deformed, and the curvature of the flexible curved surface 111 can be changed. At the same time, the zoom component 12 is provided to drive the liquid lens 11 to reciprocate along its radial direction, and the position of the liquid lens 11 is changed, so that the zoom of the liquid lens 11 can be effectively realized; and by providing a focus module 2 connected to the zoom component 12, the user can manually operate the focus module 2 to achieve fast zooming, improve photo and video effects, and enhance user experience.

As shown in FIG. 5 and FIG. 7 to FIG. 10 , in the embodiment of the present application, the zoom assembly 12 includes a pressing piece 123, a moving sleeve 122 and a zoom sleeve 121 which are connected and coaxially arranged in sequence:

The zoom sleeve 121 is in driving connection with the focus module 2, and the focus module 2 can drive the zoom sleeve 121 to rotate;

The zoom sleeve 121 is configured to be able to rotate only in the circumferential direction, and the movable sleeve 122 is configured to be able to move only in the axial direction. The movable sleeve 122 is coaxially sleeved with the zoom sleeve 121 and is in transmission connection with each other. When the focusing module 2 drives the zoom sleeve 121 to rotate, the zoom sleeve 121 can drive the movable sleeve 122 to make the movable sleeve 122 reciprocate along its axial direction, wherein the barrel wall of the movable sleeve 122 is in sliding contact with the barrel wall of the zoom sleeve 121 so that the two will not have radial relative displacement, so as to ensure that the pressing piece 123, the movable sleeve 122 and the zoom sleeve 121 always maintain a coaxial state, and avoid the situation where the movable sleeve 122 or the zoom sleeve 121 is radially offset and causes shielding of the imaging path of the liquid lens 11; and

The pressing sheet 123 has an annular sheet structure, and a through hole 1231 is formed in the center thereof. The pressing sheet 123 is arranged at the first end of the movable sleeve 122. Specifically, a plurality of overlapping sheets 1232 are arranged at intervals on the outer periphery of the pressing sheet 123, and each overlapping sheet 1232 is provided with an embedding hole 12321. A plurality of overlapping grooves 1221 are recessed at intervals on the first end surface of the movable sleeve 122, and each overlapping groove 1221 is provided with a convex column 1221. When the pressing sheet 123 is connected to the movable sleeve 122, each overlapping sheet 1232 is embedded in each overlapping groove 1221, and the convex column 12211 in each overlapping groove 1221 is inserted into the embedding hole 12321 of the corresponding overlapping sheet 1232, so as to position the pressing sheet 123 and the movable sleeve 122 circumferentially, and prevent the pressing sheet 123 from rotating relative to the movable sleeve 122 and causing wear to the liquid lens 11 when it abuts against the liquid lens 11.

The liquid lens 11 is at least partially disposed on the inner side of the movable sleeve 122 or the zoom sleeve 121. Specifically, when the movable sleeve 122 is sleeved on the outer side of the zoom sleeve 121, the liquid lens 11 is disposed on the inner side of the zoom sleeve 121, and when the movable sleeve 122 is disposed on the inner side of the zoom sleeve 121, the liquid lens 11 is disposed on the inner side of the movable sleeve 122. The pressing plate 123 abuts against the flexible curved surface 111, and a part of the flexible curved surface 111 passes through the through hole 1231. When the force applied by the pressing plate 123 to the flexible curved surface 111 changes, the radial size and curvature of the part of the flexible curved surface 111 that passes through the through hole 1231 and protrudes from the pressing plate 123 change, which is equivalent to forming a lens with different curvature radii, thereby achieving zooming.

As shown in FIGS. 7 to 11 , in the embodiment of the present application, a first guide structure 124 is provided between the zoom sleeve 121 and the movable sleeve 122. The first guide structure 124 includes a first guide rail 1241 and a first guide rod 1242. The first guide rail 1241 is provided on the wall of the zoom sleeve 121. The first guide rod 1242 is connected to the movable sleeve 122. When the movable sleeve 122 is sleeved with the zoom sleeve 121, the first guide rod 1242 is inserted into the first guide rail 1241. During the rotation of the zoom sleeve 121, the first guide rod 1242 moves along the first guide rail 1241. The first guide rod 1242 can generate a certain stroke in the axial direction of the zoom sleeve 121, thereby causing the movable sleeve 122 to move along its axial direction.

Specifically, as shown in Figures 7 to 10, the first guide rail 1241 extends along the circumference of the zoom sleeve 121, and the first guide rail 1241 extends from a position close to one end of the zoom sleeve 121 to a direction close to the other end of the zoom sleeve 121, that is, the first guide rail 1241 extends a certain distance in the circumferential and axial directions of the zoom sleeve 121. During the movement of the first guide rod 1242 along the first guide rail 1241, the zoom sleeve 121 and the movable sleeve 122 simultaneously undergo circumferential relative movement and axial relative movement, thereby driving the liquid lens 11 to move along its axial direction to achieve zooming.

As shown in Figures 9 and 10, in the embodiment of the present application, the zoom assembly 12 also includes a support seat 125, and a groove is formed on one side of the support seat 125. A portion of the liquid lens 11 is disposed in the groove, and the flexible curved surface 111 protrudes from the notch of the groove. By providing the support seat 125, the surface of the liquid lens 11 other than the flexible curved surface 111 can be supported to prevent the liquid lens 11 from being subjected to unnecessary deformation at positions other than the flexible curved surface 111 when the zoom assembly 12 presses the liquid lens 11, thereby affecting the deformation degree of the flexible curved surface 111 and thus affecting the zoom effect.

The support seat 125 is configured to be able to move only along its axial direction. The support seat 125 is connected to the zoom sleeve 121 in transmission. The zoom sleeve 121 can drive the support seat 125 to reciprocate along the axial direction of the liquid lens 11. The transmission method between the zoom sleeve 121 and the support seat 125 is similar to the transmission method between the zoom sleeve 121 and the movable sleeve 122. The movable sleeve 122 is driven to move along its axial direction by rotating the zoom sleeve 121.

As shown in Figures 9 and 10, in the embodiment of the present application, a second guide structure 126 is provided between the support seat 125 and the zoom sleeve 121, and the second guide structure 126 includes a second guide rail 1261 and a second guide rod 1262. The second guide rail 1261 is provided on the cylinder wall of the zoom sleeve 121, the second guide rod 1262 is connected to the support seat 125, and the second guide rod 1262 is inserted into the second guide rail 1261. During the rotation of the zoom sleeve 121, the second guide rod 1262 moves along the second guide rail 1261, and the second guide rod 1262 can produce a certain stroke in the axial direction of the zoom sleeve 121, thereby causing the support seat 125 to move along its axial direction.

As shown in FIGS. 9 to 11 , in the embodiment of the present application, the first guide rail 1241 and the second guide rail 1261 both extend along the circumference of the zoom sleeve 121 , the first guide rail 1241 includes a first section 12411 and a second section 12412 that are connected, and the second guide rail 1261 includes a third section 12611 and a fourth section 12612 that are connected;

The first section 12411 and the third section 12611 both extend from a position close to one end of the zoom sleeve 121 toward a direction close to the other end of the zoom sleeve 121, a first angle is formed between the first section 12411 and the second section 12412, and a second angle is formed between the third section 12611 and the fourth section 12612, and the first angle and the second angle are different in size.

It can be understood that the first guide rail 1241 and the second guide rail 1261 are both in a broken line shape, wherein the extension lengths of the first section 12411 and the third section 12611 and the extension angles relative to the axial and circumferential directions of the zoom sleeve 121 are the same. In the first stage of the rotation of the zoom sleeve 121, the first guide rod 1242 moves synchronously in the first section 12411 and the second guide rod 1262 moves synchronously in the third section 12611. During this process, the movable sleeve 122 and the support seat 125 move synchronously along the axial direction of the zoom sleeve 121, and the distance between the two remains unchanged. Zooming is achieved by adjusting the axial position of the liquid lens 11.

In the second stage of rotation of the zoom sleeve 121, the first guide rod 1242 enters into the second section 12412, and the second guide rod 1262 enters into the fourth section 12612. The second section 12412 and the fourth section 12612 have different extension angles relative to the axial and circumferential directions of the zoom sleeve 121. At this time, the direction and/or stroke of the axial movement of the support seat 125 and the movable sleeve 122 along the zoom sleeve 121 changes, so that the position between the pressing plate 123 provided at the first end of the movable sleeve 122 and the support seat 125 changes, so as to realize the change of the pressing force of the pressing plate 123 on the flexible curved surface 111, thereby adjusting the degree of deformation of the flexible curved surface 111, and realizing zooming by adjusting the curvature of the liquid lens 11.

Optionally, the range of deformation of the flexible surface 111 can be determined based on the required curvature range of the liquid lens 11, and the axial travel range of the pressing plate 123 and the support seat 125 can be further determined, thereby determining the extension length of the second section 12412 and the fourth section 12612 and the axial and circumferential extension angles relative to the zoom sleeve 121.

As shown in Figures 6, 12 and 13, in the embodiment of the present application, the focusing module 2 includes an adjusting member 21 and a transmission assembly 22. The transmission assembly 22 is respectively connected to the adjusting member 21 and the zoom sleeve 121 for transmission. By operating the adjusting member 21, the adjusting member 21 drives the transmission assembly 22 to drive the zoom sleeve 121 to rotate.

Optionally, as shown in FIG. 3 , FIG. 6 and FIG. 12 , the adjusting member 21 is an adjusting gear, and the adjusting gear is meshed with the transmission assembly 22 for transmission, and zooming is achieved by rotating the adjusting gear.

Optionally, as shown in Figures 13 and 14, the adjustment component 21 includes a rocker 211, a transmission wheel 212 and a toggle member 213. The rocker 211 and the transmission wheel 212 are both rotatably connected to the same rotating shaft. The toggle member 213 is respectively connected to the rocker 211 and the transmission wheel 212. The rocker 211 can swing around the rotating shaft and drive the toggle member 213 to toggle the transmission wheel 212 to rotate. The transmission wheel 212 drives the zoom sleeve 121 to rotate through the transmission assembly 22 to achieve zooming.

Optionally, as shown in FIG. 13 and FIG. 14 , the rocker 211 has an initial position, and elastic elements 214 are respectively provided on both sides of the rocker 211 , and the elastic elements 214 are used to reset the rocker 211 deviating from the initial position to the initial position;

There are swing limit positions on both sides of the initial position. When the rocker 211 swings from the initial position to one of the swing limit positions, the toggle member 213 toggles the transmission wheel 212 to rotate by a predetermined angle, and when the rocker 211 is reset from the swing limit position to the initial position, the transmission wheel 212 remains stationary; each time the rocker 211 is swung from the initial position to one of the swing limit positions, the transmission wheel 212 rotates by a predetermined angle, thereby achieving adjustment of the predetermined focal length of the zoom lens 1 and the zoom camera;

specifically:

A swing seat 2111 is fixedly provided on the rocker 211, and two ends of the rocker 211 protrude from two ends of the swing seat 2111;

The transmission wheel 212 is a bidirectional ratchet wheel, and a plurality of ratchet teeth 2121 are arranged at intervals on the outer circumference of the bidirectional ratchet wheel. Each ratchet tooth 2121 forms abutment surfaces on both sides of the circumference of the bidirectional ratchet wheel. One end of the rocker 211 is rotatably connected to the rotating shaft of the bidirectional ratchet wheel.

The toggle member 213 is a pawl, and the pawl includes a first pawl 2131 and a second pawl 2132. The first pawl 2131 and the second pawl 2132 respectively have a connecting end and an abutting end. The connecting end of the first pawl 2131 and the connecting end of the second pawl 2132 are respectively rotatably connected to a transfer rod 2133, and the transfer rod 2133 is fixedly connected to the swing seat 2111. The abutting end of the first pawl 2131 and the abutting end of the second pawl 2132 extend between two ratchet teeth 2121 of the bidirectional ratchet, and the abutting end of the first pawl 2131 and the abutting end of the second pawl 2132 are respectively abutted against an abutting surface of two adjacent ratchet teeth 2121. During the swinging process of the rocker 211, the bidirectional ratchet can be driven to rotate by the first pawl 2131 or the second pawl 2132 pushing against the ratchet teeth 2121;

Two elastic elements 214, the two elastic elements 214 are respectively located on both sides of the swing direction of the rocker 211 and connected to the swing seat 2111, specifically, the elastic elements 214 are springs, one end of the spring is respectively fixed by a fixing seat, and the other end of the spring is connected to the swing seat 2111;

A baffle plate 215 is provided at a position corresponding to the initial position of the rocker 211 on the circumference of the bidirectional ratchet. When the rocker 211 is at the initial position, the baffle plate 215 is located between the first claw 2131 and the second claw 2132. When the rocker 211 is swinging, the abutting end of the first claw 2131 or the abutting end of the second claw 2132 can be placed on the baffle plate 215.

Take the swing of the rocker 211 in the extending direction of the first claw 2131 as an example:

During the rotation process, the abutting end of the first pawl 2131 pushes against the Nth ratchet 2121, causing the bidirectional ratchet to rotate, and the abutting end of the second pawl 2132 is placed on the baffle 215, one elastic element 214 is compressed, and the other elastic element 214 is stretched, and when the rocker 211 swings to the swing limit position, the N+1th ratchet 2121 rotates to the position before the Nth ratchet 2121 rotates, and the N+2th ratchet 2121 rotates to the position before the N+1th ratchet 2121 rotates, the force applied to the rocker 211 is removed, and the rocker 211 is between the two elastic elements. Component 214 is reset to its initial position under the action of the elastic restoring force, the abutting end of the first claw 2131 moves to abut against the N+1th ratchet 2121, and the abutting end of the second claw slides on the baffle 215 to abut against the N+2 ratchet 2121, thus completing one swing of the rocker 211. During this process, the rotation angle of the two-way ratchet is the angle formed by the center of two adjacent ratchet teeth 2121 and the line connecting the rotation center of the two-way ratchet.
