The specific meaning of the above terms in the present invention can be understood as appropriate to those of ordinary skill in the art.

For better understanding of the present invention, the image pickup apparatus 10 and the mobile terminal according to the embodiment of the present invention will be described in detail with reference to fig. 1 to 13.

Fig. 1 and 2 schematically show the structure of an image pickup apparatus 10 according to an embodiment of the present invention. Referring to fig. 1 and 2, an image pickup apparatus 10 according to an embodiment of the present invention is provided. The imaging apparatus 10 of the present embodiment includes a guide rail 20, an imaging module 30, a locking member 40, and an elastic member 50. The camera device 10 can be applied to a mobile terminal, such as a mobile phone, a video camera, a tablet computer, or the like. The embodiment does not limit the specific type of the mobile terminal.

The guide rail 20 of this embodiment is used for guiding the camera module 30 to make a straight reciprocating motion along a predetermined track, so as to ensure the stability of the camera module 30 in the moving process and the accuracy of the moving position, and reduce the possibility of shaking or vibration in the moving process of the camera module 30. In the embodiment of the present invention, the guide rail 20 may be made of a material having wear resistance, a small friction coefficient, and a good self-lubricating property. For example, the guide rail 20 may be manufactured by processing a material such as plastic or resin, but the specific material used for manufacturing the guide rail is not limited in the present embodiment.

The imaging module 30 of the present embodiment includes a pressing member 31 and an imaging unit 32 provided to the pressing member 31. The pressing member 31 is movably connected to the guide rail 20. By applying a pressing force F to the pressing member 31 along the extending direction X of the guide rail 20, the pressing member 31 is linearly reciprocated along the guide rail 20 to switch the image pickup unit 32 between an extended position and a retracted position, in which the image pickup unit 32 in fig. 1 is in the retracted position and the image pickup unit 32 in fig. 2 is in the extended position. The pressing force F may be a stress applied to the pressing member 31 by a user through a limb (e.g., a finger), or may be a stress applied to the pressing member 31 using an external related device. When the camera unit 32 is in the extended position, the camera unit 32 is used to photograph the object. When the image pickup unit 32 is in the retracted position, the image pickup unit 32 is in a standby state and is not used to photograph an object.

The locking member 40 of the present embodiment is connected to the pressing member 31 to lock or release the pressing member 31. The locking member 40 locks the pressing member 31 when the image pickup unit 32 is in the extended position or the retracted position. When the image pickup unit 32 is in the extended position or the retracted position, and the pressing member 31 is subjected to the pressing force F, the locking member 40 releases the pressing member 31. When the pressing member 31 is locked by the locking member 40, the pressing member 31 keeps the current position, so that the imaging unit 32 is stably kept at the extended position or the retracted position, and the possibility that the imaging unit 32 cannot be kept at the extended position or the retracted position due to the position change of the pressing member 31 is reduced. The locking member 40 of the present embodiment is interlocked with the pressing member 31, and when the pressing member 31 receives the pressing force F, the locking member 40 is triggered to release the pressing member 31.

The elastic member 50 of the present embodiment is connected to the pressing member 31. While the locking member 40 releases the pressing member 31, the elastic member 50 provides the driving force in the extending direction X of the guide rail 20 to the pressing member 31 to switch the image pickup unit 32 from the retracted position to the extended position.

Referring to fig. 1, the image pickup unit 32 provided on the pressing member 31 is in the retracted position, and the locking member 40 locks the pressing member 31. After the pressing force F is applied to the pressing member 31 and removed, the locking member 40 releases the pressing member 31, so that the elastic member 50 pushes the pressing member 31 to move along the guide rail 20 until the image pickup unit 32 reaches the extended position. As shown in fig. 2, after the image pickup unit 32 reaches the extended position, the locking member 40 locks the pressing member 31 again so that the image pickup unit 32 is held at the extended position. Similarly, when the pressing force F is applied to the pressing member 31 in the extended state in fig. 2, the locking member 40 releases the pressing member 31 again. The pressing force F is continuously applied, and the pressing member 31 moves along the guide rail 20 until the imaging unit 32 provided on the pressing member 31 reaches the retracted position. Referring to fig. 1, after the image pickup unit 32 reaches the retracted position, the locking member 40 locks the pressing member 31 again so that the image pickup unit 32 is held in the retracted position. By pressing the pressing member 31 by the above operation, the one-time extending and retracting operation of the image pickup unit 32 can be completed.

The image pickup device 10 according to the embodiment of the present invention applies an external pressing force F to the image pickup assembly 30, and the image pickup unit 32 is extended or retracted under the cooperation of the guide rail 20, the locking member 40, and the elastic member 50, so that the image pickup device 10 according to the embodiment of the present invention does not need to be additionally provided with a driving mechanism (e.g., a motor and a transmission mechanism), and has a simple and compact overall structure and occupies a small installation space. When the camera device 10 of the embodiment is applied to the mobile terminal, the camera device can be used as a front camera, so that interference with the display screen is avoided, the size and the screen ratio of the display screen are improved, a full-screen is realized, and the visual experience of the mobile terminal is improved. Meanwhile, the camera device 10 of the embodiment has a simple and compact structure and low occupancy rate to the internal space of the mobile terminal, thereby saving the installation space inside the mobile terminal and optimizing the layout design of the internal parts of the mobile terminal.

Referring to fig. 1 and 3, the guide rail 20 of the present embodiment has a first guide portion 21, and the sliding seat 33 is slidably engaged with the first guide portion 21. The pressing member 31 of the present embodiment includes a sliding seat 33 and a support member 34 connected to the sliding seat 33. The camera unit 32 is disposed on the support 34. The surface of the bearing 34 facing away from the sliding seat 33 bears the pressing force F. After the image pickup unit 32 is separately mounted and fixed on the support member 34, the support member 34 and the sliding seat 33 are assembled to form the pressing member 31, so that the image pickup unit 32 is conveniently mounted and fixed, and the difficulty in processing and manufacturing the pressing member 31 is low. In one embodiment, the first guiding portion 21 of the guiding rail 20 is a straight groove, and the sliding seat 33 is provided with a convex strip matching with the shape of the straight groove, so that the sliding seat 33 is slidably engaged with the straight groove through the convex strip. In another embodiment, the first guiding portion 21 of the guiding rail 20 is a rib extending along a straight line, and the sliding seat 33 is provided with a straight groove matching with the shape of the rib, so that the sliding seat 33 is slidably engaged with the rib through the straight groove. Alternatively, the straight groove may be a U-shaped groove having a U-shaped section or a dovetail groove having a dovetail-shaped section. The sliding seat 33 of the present embodiment is in sliding fit with the first guide portion 21, which is beneficial to reduce the friction resistance between the pressing member 31 and the guide rail 20, and is also beneficial to improve the moving accuracy and the moving stability of the pressing member 31.

The guide rail 20 of this embodiment also has a second guide portion 22, and the support member 34 is slidably engaged with the second guide portion 22. In one embodiment, the second guide portion 22 of the guide rail 20 is a straight groove, and the support member 34 is provided with a rib matching the shape of the straight groove, so that the support member 34 is slidably engaged with the straight groove via the rib. In another embodiment, the second guiding portion 22 of the guiding rail 20 is a rib extending along a straight line, and the supporting member 34 is provided with a straight groove matching with the shape of the rib, so that the supporting member 34 is slidably engaged with the rib through the straight groove. Alternatively, the straight groove may be a U-shaped groove having a U-shaped section or a dovetail groove having a dovetail-shaped section. In this way, the sliding seat 33 and the support 34 included in the pressing member 31 are respectively and independently in sliding fit with the first guide portion 21 and the second guide portion 22 of the guide rail 20, so that the guide rail 20 forms a double limit for the pressing member 31, the movement accuracy and the movement stability of the entire pressing member 31 are further improved, and the positional stability of the imaging unit 32 is ensured.

Referring to fig. 4 and 5, the support member 34 of the present embodiment includes a receiving portion 340 having a receiving cavity 340a and two legs 341 extending from the same side of the receiving portion 340. The two legs 341 are spaced apart from each other in a direction perpendicular to the extending direction X of the rail 20. The surface of the accommodating portion 340 facing away from the slide base 33 bears the pressing force F. The structural design of the support member 34 of the present embodiment, on the one hand, makes the structure thereof more lightweight on the premise that the structural strength thereof satisfies the requirement; on the other hand, the space between the two legs 341 may form a yield to reduce the space occupancy. The number of the legs 341 of the present embodiment is not limited to two, and may be at least three. At least three legs 341 are provided at intervals in a direction perpendicular to the extending direction X of the rail 20. In one embodiment, the sliding seat 33 has a projection 330 that projects toward the rail 20. The leg 341 extends at least partially between the sliding seat 33 and the rail 20 and has a catch 341a that engages with the protrusion 330. The legs 341 are snap-connected to the protrusions 330 via the snap grooves 341 a. The supporting member 34 is connected with the sliding seat 33 in a clamping manner through the supporting leg 341, so that when the supporting member 34 is connected with the sliding seat 33, no additional fastener is needed, and the supporting member 34 and the sliding seat 33 are compact in structure and quick and convenient to connect. The camera unit 32 is accommodated in the accommodating cavity 340a, so that the space occupancy rate of the camera unit 32 is reduced, the overall compactness of the camera device 10 is further improved, and meanwhile, the accommodating part 340 protects the camera unit 32 and reduces the possibility that the camera unit 32 scrapes or collides with external objects in the moving process or in the extending position and the retracting position. In this embodiment, the support 34 is slidably engaged with the second guide portion 22 of the guide rail 20 via the leg 341.

The support 34 of this embodiment also includes a stop flange 342. A position-limiting flange 342 is provided on the outer surface of the receiving portion 340 in the region near the leg 341. The extending direction of the position-restricting flange 342 intersects the extending direction of the leg 341. The stop flange 342 of the present embodiment is capable of abutting other external structural members to limit continued movement of the support 34 so that the camera unit 32 is stably maintained in the extended position. In one embodiment, the receiving portion 340 has a flat cylindrical structure, the receiving cavity 340a has a rectangular structure, and the limiting flange 342 protrudes from the outer circumferential surface of the receiving portion 340.

In one embodiment, referring to fig. 3, the rail 20 has a relief notch 23. When the imaging unit 32 is in the retracted position, the accommodating portion 340 provided with the imaging unit 32 is accommodated in the escape notch 23. Thus, on the one hand, the guide rail 20 is more lightweight in structure; on the other hand, since the accommodating portion 340 is accommodated inside the guide rail 20, the space occupied by the accommodating portion 340 in the extending direction X of the guide rail 20 is reduced, the overall compactness of the imaging apparatus 10 is effectively improved, and the overall space occupancy rate of the imaging apparatus 10 is reduced.

Referring to fig. 6, the sliding seat 33 of the present embodiment has a first positioning portion 331, and the guide rail 20 has a second positioning portion 24. The first positioning portion 331 and the second positioning portion 24 are both provided to correspond to each other in the extending direction X of the guide rail 20. The elastic member 50 of the present embodiment is provided between the first positioning portion 331 and the second positioning portion 24. The elastic component 50 applies acting force along the extending direction X of the guide rail 20 to the sliding seat 33, effectively reduces the component force of the sliding seat 33 along the direction intersecting the extending direction X of the guide rail 20, thereby reducing the offset of the sliding seat 33 in the direction intersecting the extending direction X of the guide rail 20 and further ensuring that the whole moving process of the pressing component 31 is more stable. In one embodiment, the first positioning portion 331 and the second positioning portion 24 are both columnar structures. The elastic member 50 is a coil spring. The axial direction of the coil spring is the same as the extending direction X of the guide rail 20, so that the elastic force in the extending direction X of the guide rail 20 is provided to the slide holder 33, and the coil spring has a simple structure and satisfies the requirement of light weight. In the embodiment, one end of the elastic member 50 is sleeved on the first positioning portion 331, and the other end is sleeved on the second positioning portion 24, so that no additional fastening member or connecting member is required in the connection process of the three, and the assembly process is fast and convenient.

In one embodiment, the surface of the sliding seat 33 facing the rail 20 has a receiving groove 332. The receiving groove 332 extends in the extending direction X of the rail 20. The first positioning portion 331 and the second positioning portion 24 are both provided corresponding to the accommodation groove 332. The elastic member 50 is at least partially received in the receiving groove 332. In this way, the elastic member 50 is at least partially covered by the sliding seat 33, so that on one hand, the elastic member 50 is restricted by the sliding seat 33 and is not easily bent and deformed; on the other hand, the sliding seat 33, the elastic component 50 and the guide rail 20 are more compact, so that the overall compactness of the camera device 10 is improved, and the space occupancy rate of the camera device 10 is effectively reduced.

The sliding seat 33 of the present embodiment includes a main body 33a and two suspension arms 33b connected to the main body 33 a. The two cantilevers 33b are spaced apart in a direction perpendicular to the extending direction X of the guide rail 20 to form a gap therebetween, thereby making the structure of the sliding seat 33 itself more lightweight. In embodiments where the support 34 includes a receptacle 340 and legs 341, the gap is positioned to correspond to the gap formed between each leg 341. The cantilever 33b extends in a direction close to the camera unit 32, and the support 34 is connected to the main body 33 a.

Referring to fig. 7, the surface of the sliding seat 33 facing away from the guide rail 20 of the present embodiment is provided with a track limiting groove 333. The track limiting groove 333 has a retraction lock position 333a and an extension lock position 333 b. The locking member 40 includes a link. The connecting rod has two opposite end portions and a middle portion. One end of the connecting rod is rotatably connected to the guide rail 20, and the other end thereof extends into the trajectory limiting groove 333. One end of the link rod, which protrudes into the trajectory limiting groove 333, moves between the retraction locking position 333a and the protrusion locking position 333b to lock the pressing member 31, thereby locking the image pickup unit 32 at the retracted position or the protruded position. In this embodiment, the locking and releasing of the pressing member 31 are realized by the joint cooperation of the connecting rod and the trajectory limiting groove 333. One end of the connecting rod is limited and restricted by the track limiting groove 333, and the motion track is not changed accurately, so that the connecting rod is ensured to be positioned at the retraction locking position 333a or the extension locking position 333b accurately when the camera unit 32 reaches the retraction position or the extension position. In one embodiment, the guide rail 20 is provided with a coupling hole, and an end of the link is directly inserted into the coupling hole to be rotatably coupled with the guide rail 20. In the extending direction X of the guide rail 20, the retraction locking position 333a and the extension locking position 333b are aligned with each other, and the coupling hole is offset from the retraction locking position 333a and located outside the retraction locking position 333 a.

In one embodiment, referring to fig. 7 and 8, the trajectory limiting groove 333 includes a heart-shaped non-return groove section 334 and a straight groove section 335. Referring to fig. 10, one end of the link rotatably connected to the guide rail 20 is a long arm section 40a, and the long arm section 40a is perpendicular to the middle portion. One end of the connecting rod extending into the track limiting groove 333 is a short arm section 40b, and the short arm section 40b is perpendicular to the middle part. The heart-shaped non-return groove section 334 has a first tip portion 334a and a second tip portion 334b spaced along the extension direction X of the rail 20. The retraction lock bit 333a is disposed at the first tip portion 334 a. The straight groove section 335 communicates with the second tip portion 334b and extends in the extending direction X of the guide rail 20. The extended locking stop 333b is disposed on the straight slot section 335 at a region distal from the second tip 334 b. The short arm segment 40b on the connecting rod is only capable of unidirectional movement (e.g., clockwise or counterclockwise as shown) along the heart-shaped non-return slot segment 334. The intermediate portion of the link is comprised of an intersection with the straight slot segment 335. When the camera unit 32 is in the retracted position, the pressing force F is applied to the pressing member 31 and removed in time, and at this time, the track limiting groove 333 on the pressing member 31 moves, so that the short arm section 40b on the link rod leaves the retraction locking position 333a to release the pressing member 31. The short arm segment 40b on the link moves in the direction of movement shown in phantom in fig. 1. The short arm segment 40b on the link enters the straight slot segment 335 after moving out of the heart-shaped anti-slot segment 334 and finally reaches the extended locking position 333b, while the camera unit 32 is just in the extended position and stops moving. Similarly, when the camera unit 32 is in the extended position, the pressing member 31 is continuously pressed by the pressing force F, and at this time, the track-limiting groove 333 on the pressing member 31 moves, so that the short arm section 40b on the link moves away from the extension-locking position 333b to release the pressing member 31. The short arm segment 40b on the link moves in the direction of movement shown by the dashed line in fig. 2. The short arm segment 40b on the link, after moving out of the straight slot segment 335, re-enters the no-return-from-heart slot segment 334 and finally reaches the retracted locking position 333a, while the camera unit 32 is just in the retracted position and stops moving. When the short arm section 40b of the link moves in the track limiting groove 333, the long arm section 40a of the link rotates in the connecting hole of the guide rail 20.

In one embodiment, referring to FIG. 9, the bottom surface of the heart shaped check channel segment 334 includes at least two step surfaces 3341 and a check surface 3342 connecting two adjacent step surfaces 3341. At least two stepped surfaces 3341 are arranged along the extension direction of the heart-shaped check groove section 334, wherein one of the check surfaces 3342 forms a retraction locking position 333a at the first tip portion 334 a. When the end of the link is in the retracted locking position 333a, the short arm segment 40b on the link abuts against the check surface 3342 and is stably in the locked state.
