The first lens assembly 220 can rotate and expand and contract with the outer cover 230 , so as to be dislocated or opposite to the module body 210 , thereby realizing the switching of the telescopic state of the optical module 200 .

At the same time, the outer cover 230 is provided with a light-transmitting area 231 opposite to the first lens assembly 220 , and the ambient light can be introduced into the optical module 200 through the light-transmitting area 231 and irradiated to the first lens assembly 220 and the main body of the module. 210, so as to provide illumination conditions required by the optical module 200 for imaging. Furthermore, the cover 230 and the first through hole 110 are blocked and matched to prevent external dust and stains from entering the optical module 200 and causing pollution.

Furthermore, the cover 230 is a light-shielding cover, which can prevent light from entering the optical module 200 from areas other than the light-transmitting area 231 , so as to avoid abnormal conditions such as astigmatism that affect the shooting.

In some embodiments, as shown in FIG. 14 , there are multiple first lens assemblies 220 , the multiple first lens assemblies 220 are arranged at intervals, there are multiple light-transmitting regions 231 , and each light-transmitting region 231 is associated with one first lens The components 220 are disposed opposite to each other, the plurality of first lens components 220 can be rotated with the cover 230 to a position opposite to the module body 210 , and the optical parameters of the plurality of first lens components 220 are not all the same.

When the first lens assembly 220 is rotated, the first lens assembly 220 can be attached to the guide surface. and slide into the top of the second lens assembly 211 along the inclined direction of the guide surface, so as to form an opposite arrangement with the second lens assembly 211, so as to realize the extension of the optical module 200; the first lens assembly 220 can also be attached to the guide and slide into the avoidance space 213 along the inclined direction of the guide surface, so as to form a dislocation arrangement with the second lens assembly 211 , so as to realize the retraction of the optical module 200 . It can be seen that the extension and retraction of the optical module 200 can be more easily achieved through the sliding fit of the guide portion 214 to the first lens assembly 220 .

In some embodiments, as shown in FIG. 5 and FIG. 6 , the inner side wall of the outer cover 230 is provided with a matching protrusion 240 , the module body 210 is provided with a guide rail 232 , and the guide rail 232 includes a spiral guide section 2321 . As shown in FIGS. 9 to 12 , the matching protrusions 240 are slidably engaged with the guide rails 232 , and the outer cover 230 can be rotatably retracted into the equipment housing 100 through the sliding cooperation between the matching protrusions 240 and the screw guide segments 2321 . Or at least partially protrude out of the device housing 100 through the first through hole 110 . That is, the outer cover 230 can be spirally ascended or spirally descended relative to the module body 210 .

At the same time, it should be pointed out that the spiral upward or spiral downward of the outer cover 230 can be realized by manual operation, or can be realized by installing a driving device. Referring to FIG. 9 and FIG. 10 , the embodiment of the present application realizes the spiral up or spiral down of the housing 230 by installing the driving mechanism 250 on the electronic device. The driving mechanism 250 includes a driving main body 251 and a transmission mechanism 253 . The driving main body 251 is connected with the outer cover 230 through the transmission mechanism 253 and can drive the outer cover 230 to rotate. Here, the driving body 251 is an energy source that provides driving force, such as a motor, a motor, etc., and the transmission mechanism 253 is used to transmit the energy generated by the driving body 251 to the outer cover 230, so that the outer cover 230 can be rotated and stretched. For example, the transmission mechanism 253 is a Multi-stage gear transmission pair, the driving main body 251 is a motor, and a driven gear is arranged on the outer cover 230, and the multi-stage gear transmission pair is driven by the motor to rotate and expand the outer cover 230. For example, the driving main body 251 is a motor, and the output of the driving main body 251 is realized. The end is connected with the inner gear ring. The peripheral wall of the outer cover 230 can be provided with an outer gear ring. The inner gear ring is sleeved and meshed with the outer gear ring to form a transmission mechanism 253. The drive body 251 can also be driven by the meshing of the inner and outer gear rings on the transmission mechanism 253. The cover 230 rotates and expands. This way of realizing the lifting and lowering in a rotational manner can improve the adjustment efficiency, and is also beneficial to simplify the structure of the driving device.

Referring to FIG. 13, in a further embodiment, the transmission mechanism 253 may specifically include a worm 2531, a gear 2532 and a plurality of meshing teeth 2533, the driving body 251 is connected to the worm 2531, the worm 2531 is meshed with the gear 2532, and the plurality of meshing teeth 2533 are fixed The gears 2532 are arranged on the outer cover 230 and arranged along the circumferential direction of the outer cover 230 . In this way, the transmission mechanism 253 transmits in the following order: the driving main body 251 drives the worm 2531 to rotate, the worm 2531 drives the gear 2532 to follow the rotation, and the gear 2532 drives the plurality of meshing teeth 2533 to rotate. Through the rotation of the plurality of meshing teeth 2533 and the sliding fit between the helical guide section 2321 and the mating protrusion 240, the outer cover 230 is finally rotated and stretched, that is, the outer cover 230 spirally ascends or the bolts descend. Since the transmission mechanism 253 is driven by meshing, it is beneficial to improve the transmission accuracy.

The transmission mechanism 253 can adopt the combined form of a worm gear pair and a gear pair to achieve smooth transmission and can realize reversing transmission, so that the layout of the relevant components in the transmission mechanism 253 can make full use of the accommodation space in the equipment housing 100, Improve the space utilization rate, which is more conducive to the realization of light and thin electronic equipment; at the same time, the worm gear and worm pair have a self-locking function, that is, the transmission direction can only be that the worm 2531 drives the gear 2532 to rotate, and the gear 2532 will be locked when it wants to drive the worm 2531 to rotate. In the extended state, the outer cover 230 can be prevented from being twisted by an external force to cause abnormal retraction.

At the same time, it should be pointed out that since the outer cover 230 is retractable, it should be ensured that the tooth thickness of the gear 2532 is greater than the tooth thickness of the meshing teeth 2533, so that when the gear 2532 drives the meshing teeth 2533 to rotate, there is no space between the meshing teeth 2533 and the gear 2532. They can be slid with each other along the through direction of the first through hole 110 to prevent the engagement failure caused by the separation of the two.

An optional structure of the gear 2532 can be a composite gear structure formed by a combination of a gear part and a worm gear part, the gear part and the worm gear part are coaxially arranged, wherein the worm gear part and the worm 2531 form a worm gear and worm pair, and the gear part is connected with a plurality of gear parts. The meshing teeth 2533 form a gear transmission pair, so that the worm 2531 drives the gear 2532 to rotate through the worm gear part, and then the driving gear 2532 drives the plurality of meshing teeth 2533 to rotate through the gear part, thereby realizing the rotation and expansion of the housing 230. The gear part can use spur gears to use the linear tooth direction of the gear part to form a guiding effect on the meshing teeth 2533, and the gear part can also use helical gears to achieve smooth transmission.

Another optional structure of the gear 2532 can be a helical gear. The helical gear forms a worm gear pair with the worm 2531, and a gear transmission pair with the meshing teeth 2533, which can also realize the rotation and expansion of the cover 230, simplifying the gear 2532. At the same time of manufacturing difficulty, it achieves the effect of smooth transmission. Of course, in this case, a slight gap needs to be left between the outer cover 230 and the hole wall of the first through hole 100 to accommodate the slight lateral movement of the outer cover 230 .

Furthermore, the plurality of meshing teeth 2533 and the housing 230 are integrally formed, which can reduce the difficulty of manufacture, simplify the manufacturing process, and facilitate installation. Of course, the plurality of meshing teeth 2533 and the housing 230 may also be combined, for example, a plurality of meshing teeth 2533 constitute a single gear ring that is clamped on the periphery of the housing 230, which will not be described in detail here.

In some embodiments, as shown in FIGS. 6 , 11 and 12 , the guide track 232 further includes a leveling section 2322 . The first end of the helical guide section 2321 is adjacent to the outer port of the first through hole 110 . The horizontal adjustment section 2322 is connected to the first end of the helical guide section 2321 and is parallel to the surface where the outer port of the first through hole 110 is located.

Such an arrangement enables the matching protrusion 240 to slide into the horizontal adjustment section 2322 from the screw guide section 2321 when the outer cover 230 is extended, and the first lens assembly 220 can both slide through the sliding of the matching protrusion 240 in the horizontal adjustment section 2322. Keep the axial position of the first through hole 110 fixed, and can also rotate around the hole axis of the first through hole 110 to calibrate the position of the first lens assembly 220, so that it can accurately achieve the alignment with the second lens assembly 211. relative position. As shown in FIG. 14 , what is more important is that when there are multiple first lens assemblies 220 , different first lens assemblies 220 can be selected to rotate as to the second lens by sliding the sliding protrusions 240 in the horizontal adjustment section 2322 . The components 211 are set relative to each other to form different cameras, and during this selection process, the distance between the first lens component 220 and the second lens component 211 is always kept constant, so as to more conveniently and effectively meet the diverse needs of users.

At the same time, it should be noted that, as shown in FIG. 5 and FIG. 6 , the guide rails 232 can be arranged in multiple groups in the circumferential direction of the module body 210 , and the matching protrusions 240 are also arranged in multiple groups on the inner wall of the outer cover 230 in a ring shape, and the matching protrusions 240 are also arranged in multiple groups in a ring shape. The number and position of the protrusions 240 correspond to the guide rails 232 , and such a multi-group arrangement is more conducive to the expansion and contraction of the optical module 200 , so as to ensure a stable force during the transmission process.

The electronic devices disclosed in the embodiments of the present application may be mobile phones, tablet computers, e-book readers, wearable devices, game consoles, and other devices, and of course other types of devices. The embodiments of the present application do not limit the specific types of electronic devices.

The above embodiments of this application mainly describe the differences between the various embodiments. As long as the different optimization features of the various embodiments are not contradictory, they can be combined to form better embodiments. No longer.
