The camera mechanism 100 may include a first housing 10, a second housing 20, a seal 30, a drive assembly 40, and an imaging assembly 50. Specifically, the first housing 10 may have a top plate 11 and a housing chamber 101, and the top plate 11 is provided with a telescopic hole 111 communicating with the housing chamber 101. The second housing 20 includes a main body 21 and a first fixing plate 22 fixed to the main body 21, wherein the main body 21 is at least partially received in the receiving cavity 101 and one end of the main body is inserted into the telescopic hole 111. The first fixing plate 22 is disposed at a distance from the top plate 11, and one end of the sealing member 30 is connected to the first fixing plate 22, and the other end is connected to the top plate 11, so as to prevent external dust, moisture, etc. from entering the camera mechanism 100 from the gap between the body 21 and the telescopic hole 111.

It should be noted that the terms "first," "second," and "third" are used herein for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implying a number of technical features being indicated. Thus, a feature defining "a first", "a second", and "a third" may explicitly or implicitly include at least one such feature. In the description of the present application, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.

The driving assembly 40 is accommodated and fixed in the accommodating cavity 101 to be fixed with the first housing 10; the driving assembly 40 is connected to the second housing 20, so that the second housing 20 moves relative to the first housing 10, and is used for driving the second housing 20 to extend or retract into the accommodating cavity 101. The imaging assembly 50 is accommodated in the second housing 20, and can extend or retract into the accommodating cavity 101 along with the second housing 20, so as to adjust the focal length of the imaging assembly 50, thereby improving the imaging performance of the camera mechanism 100.

Alternatively, the first housing 10 may include a top plate 11, a bottom plate 12, and a connecting plate 13 connecting the top plate 11 and the bottom plate 12, which are disposed opposite to each other at intervals, and the top plate 11, the bottom plate 12, and the connecting plate 13 enclose a housing cavity 101 for housing the second housing 20, the sealing member 30, and the driving assembly 40. Wherein, one end of the driving assembly 40 may be fixed to the base plate 12, so that the driving assembly 40 is connected with the first housing 10.

The second housing 20 includes a main body 21 and a first fixing plate 22 fixed to the main body 21. The main body 21 is cylindrical, and specifically, the main body 21 includes a circular top wall 211 and a side wall 212 extending from the top wall 211, and the top wall 211 and the side wall 212 enclose a receiving chamber 210. The image forming assembly 50 is accommodated in the accommodating chamber 210 and is movable with the second housing 20. Wherein, the shape of the top wall 211 corresponds to the shape of the telescopic hole 111, in other words, the telescopic hole 111 is circular, so that the top wall 211 is matched with the top plate 11.

Specifically, when the second housing 20 protrudes from the accommodating chamber 101, the top wall 211 protrudes from the top plate 11; when the second housing 20 accommodates the cavity 101, the top wall 211 is flush with the top plate 11 to improve the uniformity and expressiveness of the appearance of the camera mechanism 100.

Optionally, the body portion 21 may further include a light-transmitting plate 213. The top wall 211 may be provided with a lens 51 hole 2110, the light-transmitting plate 213 may be mounted in the lens 51 hole 2110, and external light may enter the imaging assembly 50 through the lens 51 hole 2110. In other embodiments, the light-transmitting plate 213 is integrally formed with the top plate 11, in other words, the top wall 211 is made of a light-transmitting material, so that the top wall 211 can directly transmit light.

The first fixing plate 22 is annular, and the first fixing plate 22 is sleeved on the side wall 212 and the inner annular surface of the first fixing plate is fixed with the side wall 212. The two ends of the sealing member 30 are respectively connected to the first fixing plate 22 and the top plate 11, and when the main body portion 21 extends out from the telescopic hole 111, the first fixing plate 22 can be close to the top plate 11, so that the sealing member 30 is correspondingly compressed. In this embodiment, the first fixing plates 22 are disposed in parallel with the top plate 11 at intervals, so that the sealing member 30 is uniformly stressed in the compression process, and the sealing member 30 can be deformed according to a preset shape. In other embodiments, the first fixing plate 22 may be disposed at an angle with respect to the top plate 11, which is not particularly limited herein.

The second housing 20 may further include a second fixing plate 23 fixed on the main body 21, where the second fixing plate 23 is connected to the driving assembly 40, and can enable the second housing 20 to extend or retract into the accommodating cavity 101 under the driving of the driving assembly 40. It will be appreciated that the second fixing plate 23 is disposed on the side of the main body 21 close to the bottom plate 12, and the first fixing plate 22 is disposed on the side of the main body 21 close to the top plate 11, so as to avoid that the second fixing plate 23 affects the normal operation of the sealing member 30.

The driving assembly 40 may include a driving motor, a screw and a screw nut, wherein a rotation shaft of the driving motor is fixed to the screw and coaxially disposed, such that the driving motor can drive the screw to rotate, wherein the screw is disposed along a movement direction of the second housing 20. The lead screw nut is screw-coupled with the lead screw and fixed with the second fixing plate 23 so that the driving motor can drive the second housing 20 to extend or retract from the telescopic hole 111.

The imaging assembly 50 may include a lens 51, an elastic member 52, a photosensitive module 53, and a focusing member 54, wherein the elastic member 52 is located between the lens 51 and the photosensitive module 53 for elastically connecting the lens 51 and the photosensitive module 53. The focusing element 54 is disposed around the lens 51 for automatically focusing the lens 51.

Specifically, an end of the lens 51 away from the elastic member 52 abuts against the top wall 211, and a side of the photosensitive module 53 away from the elastic member 52 abuts against the bottom plate 12. When the second housing 20 is retracted from the telescopic hole 111 into the accommodating chamber 101, the top wall 211 of the second housing 20 is close to the bottom plate 12, and the lens 51 moves along with the top wall 211 and presses the elastic member 52, so that the elastic member 52 is in a compressed state; when the second housing 20 extends out of the accommodating cavity 101 from the telescopic hole 111, the top wall 211 of the second housing 20 is far away from the bottom plate 12, and the elastic member 52 provides an elastic restoring force so that the lens 51 can move along with the top wall 211.

The photosensitive module 53 may include a filter 531, an image sensor 532, and a supporting portion 533, wherein the filter 531 and the image sensor 532 are disposed at intervals along the optical axis direction of the lens 51, and the supporting portion 533 is located between the filter 531 and the image sensor 532 for connecting the filter 531 and the image sensor 532.

Specifically, the filter 531 may be disposed between the lens 51 and the image sensor 532, and the filter 531 is mainly used to filter infrared light to increase the imaging effect of the camera mechanism 100. The image sensor 532 may be primarily configured to receive light from the lens 51 and convert the light signal into an electrical signal to facilitate the imaging requirements of the camera mechanism 100. That is, the image sensor 532 may be configured to convert an optical signal collected by the lens 51 into an electrical signal. The external light may sequentially pass through the lens 51 and the optical filter 531 to act on the image sensor 532. The image sensor 532 may be disposed opposite the lens 51 in the optical axis direction of the lens 51.

Theoretically, the close fitting of the seal member 30 to the pop-up portion of the main body portion 21 is advantageous in improving the sealing performance of the seal member 30, but is difficult to achieve in practice. Specifically, in the related art, the main body portion 21 of the second housing 20 generally has a directional profile, and when the seal member 30 is abutted against the pop-up portion of the main body portion 21, the design of the seal member 30 at the square corner position of the main body portion 21 becomes difficult. Specifically, when the interference of the seal member 30 at the square corner position of the main body portion 21 is too small, that is, the seal member 30 is disposed in a gap with the main body portion 21, the seal member 30 cannot be sufficiently attached to the main body portion 21, and the sealing effect is poor; when the interference of the sealing element 30 at the square corner position of the main body portion 21 is too large, that is, the sealing element 30 is attached to the main body portion 21, the interference of the sealing element 30 at the corner position is stacked, the friction is increased, and the reliability of the use of the sealing element 30 is affected.

To solve the above problems, in another related art, the sealing member 30 is generally cylindrical to reduce interference and friction at the square corner of the main body 21, but the cylindrical sealing member 30 increases additional space for use, contrary to the original purpose of miniaturization of the module. In addition, the sealing member 30 is repeatedly folded during temperature change or reciprocating movement along with the second housing 20, so that the problems of flanging, stacking randomness, abrasion and the like are easy to occur, and the reliability and the service life of the sealing member 30 are affected. In view of this, it is necessary to provide a new seal 30.

Referring to fig. 4, fig. 4 is a schematic perspective view of a sealing member in the camera mechanism shown in fig. 3. The sealing member 30 may include a sealing film 31 and two fixing rings 32 connected to both ends of the sealing film 31. Specifically, the sealing film 31 is in a hollow cylindrical structure, the fixing ring 32 may be in a ring shape, and the inner ring is connected with the sealing film 31, so that the sealing film 31 and the fixing ring 32 can be sleeved on the main body of the second housing 20 at the same time. One fixing ring 32 may be fixed to the top plate 11 by using an adhesive material such as glue, and the other fixing ring 32 may be fixed to the first fixing plate 22 by using glue, so as to realize the fixed connection between the sealing member 30 and the first and second shells 10 and 20.

In one embodiment, the fixing ring 32 may be made of a hard material, and the sealing film 31 may be connected to the fixing ring 32 by injection molding. It will be appreciated that the fixing ring 32 may be attached to the top plate 11 and the first fixing plate 22, and the sealing member 30 may be connected to the first housing 10 and the second housing 20 by using other adhesive materials such as glue.

In yet another embodiment, the material of the fixing ring 32 may be the same as that of the sealing film 31 and integrally formed, so that on one hand, the reliability of the sealing clip may be improved, and on the other hand, the production process of the sealing member 30 may be simplified, and the production efficiency of the sealing member 30 may be improved.

Referring to fig. 5 to 6, fig. 5 is a schematic perspective view of a sealing film in the sealing member shown in fig. 4; fig. 6 is a schematic front view of the sealing film shown in fig. 5. The sealing film 31 may include at least two sealing rings 311 (such as a first sealing ring 311a and a second sealing ring 311 b) that are stacked and connected in sequence, wherein the first sealing ring 311a and the second sealing ring 311b are stacked and integrally formed.

Referring to fig. 7 to 9, fig. 7 is a schematic cross-sectional view of the sealing film shown in fig. 6 along the cross-section A-A; FIG. 8 is a schematic cross-sectional view of the seal ring in the seal membrane shown in FIG. 7 in the B-B direction;

fig. 9 is a schematic cross-sectional view of the seal ring in the sealing film shown in fig. 7 in the direction C-C. Specifically, the sealing ring 311 may include at least two first connectors 3111 and at least two second connectors 3112, where the first connectors 3111 and the second connectors 3112 are alternately disposed in sequence and end to end. Each first connector 3111 is symmetrically disposed about a predetermined plane Q (i.e., a plane perpendicular to the axis of the seal ring 311) and has a first opening 3010, and the opening direction of the first opening 3010 is toward the inside of the seal ring 311; each second connector 3112 is symmetrically disposed about the predetermined plane Q and has a second opening 3020, the opening direction of the second opening 3020 facing away from the inside of the sealing ring 311.

In one embodiment, each first connector 3111 includes two first connection pieces 301 symmetrically disposed about a predetermined plane Q (i.e., a plane perpendicular to an axis of the seal ring 311), the two first connection pieces 301 are disposed at a first included angle α, and an opening direction of the first opening 3010 of the first included angle α faces an inside of the seal ring 311; the second connector 3112 includes two second connecting pieces 302 symmetrically disposed about the preset plane Q, the two second connecting pieces 302 are disposed at a second included angle β, and an opening direction of a second opening 3020 of the second included angle β faces away from the inside of the sealing ring 311.

Referring to fig. 10 to 12, fig. 10 is a schematic cross-sectional view of another embodiment of the sealing film shown in fig. 6 along the cross-section A-A; FIG. 11 is a schematic cross-sectional view of the seal ring of the sealing membrane of FIG. 10 taken along the direction D-D; FIG. 12 is a schematic cross-sectional view of the seal ring in the sealing film shown in FIG. 10 in the E-E direction. In yet another embodiment, each first connector 3111 includes two circular arc-shaped first connection pieces 301 symmetrically disposed about the preset plane Q, and the two first connection pieces 301 enclose a first opening 3010 formed in a circular arc-shaped cross section; each second connector 3112 includes two circular arc-shaped second connection pieces 302 symmetrically disposed about the preset plane Q, and the two second connection pieces 302 enclose a second opening 3020 formed in a circular arc-shaped cross section.

One end of the two first connection pieces 301 of each first connector 3111 corresponds to and is connected with one end of the two second connection pieces 302 of one second connector 3112, so that the first connectors 3111 and the second connectors 3112 are alternately arranged in sequence and are connected end to end.

Referring to fig. 6 to fig. 9, in one embodiment, taking an example that when the two first connection plates 301 are disposed at the first angle α and the two second connection plates 302 are disposed at the second angle β, when the sealing ring 311 is in the extreme compression state, the two first connection plates 301 of the first connection member 3111 may be disposed at the same angle, that is, the first angle α is disposed at 0 °, and similarly, the two second connection plates 302 of the second connection member 3112 are disposed at the same angle, that is, the second angle β is disposed at 0 °. When the seal ring 311 is in the ultimate tensile state, the two first connection pieces 301 of the second connection piece 3112 may be in the same plane, that is, the first included angle α is set at 180 °, and similarly, the two second connection pieces 302 of the second connection piece 3112 are in the same plane, and the second included angle β is set at 180 °.

As can be appreciated, when the sealing ring 311 is compressed or stretched, since the opening direction of the first included angle α of the first connecting piece 301 faces the inside of the sealing ring 311, the opening direction of the second included angle β of the second connecting piece 302 faces away from the inside of the sealing ring 311, and the first connecting pieces 3011 and the second connecting pieces 3012 are alternately arranged in sequence, so that the first connecting piece 301 more easily drives the adjacent second connecting pieces 302 to synchronously move, and further, the first connecting piece 301 and the second connecting pieces 302 (i.e. the parts of the sealing ring 311) can bear extrusion acting force relatively uniformly, so that the first connecting piece 301 and the second connecting pieces 302 of the sealing ring 311 are prevented from being randomly deformed, and the sealing films 31 are randomly stacked.

In one embodiment, the sealing ring 311 includes two first connectors 3111 and two second connectors 3112, where the two first connectors 3111 are disposed at intervals, and the two second connectors 3112 are disposed at intervals, that is, the connection between the first connectors 3111 and the second connectors 3112 has an angle. In other embodiments, the seal ring 311 may further include three first connectors 3111 and three second connectors 3112, which are listed herein.

Alternatively, the two first connectors 3111 may be disposed at a parallel interval, and the two second connectors 3112 may be disposed at a parallel interval and perpendicular to the first connectors 3111, respectively, that is, the projected shape of the seal ring 311 on the predetermined plane Q is substantially rectangular. Of course, the two second connectors 3112 may also be disposed parallel to the interval and disposed at an included angle with respect to the first connector 3111, that is, the projection shape of the seal ring 311 on the predetermined plane Q is substantially parallelogram.

In other embodiments, the projection shape of the sealing ring 311 on the preset plane Q may be trapezoid, square or other quadrangles, which is not limited herein. That is, the projection shape of the seal ring 311 on the preset plane Q may be set according to the axial cross-sectional shape of the main body 21.

Further, the first connection piece 301 may include a first long side 3011 and a first short side 3012 disposed at a parallel interval, and two first connection sides 3013 connecting the first long side 3011 and the first short side 3012, wherein the first short side 3012 is located on the preset plane Q, that is, the two first connection pieces 301 of the first connector 3111 are symmetrical about the first connection side 3013.

It can be appreciated that when the sealing ring 311 is compressed or stretched, the first connecting piece 301 can drive the second connecting piece 302 to move synchronously, so that the first connecting piece 301 and the second connecting piece 302 can bear the extrusion force relatively uniformly, and the connection position of the first connecting piece 301 and the second connecting piece 302 of the sealing ring 311 is prevented from being randomly deformed, so that the sealing films 31 are randomly stacked.

In this embodiment, the first connecting piece 301 may be in an isosceles trapezoid shape, wherein the first short side 3012 is an upper bottom side of the trapezoid in the first connecting piece 301, the first long side 3011 is a lower bottom side of the trapezoid in the first connecting piece 301, and the first connecting side 3013 is a waist side of the trapezoid in the first connecting piece 301.

And one end of each of the two second connecting pieces 302 is clamped between the two first connecting pieces 301, and the second connecting pieces 302 are connected with the corresponding first connecting pieces 301, so that the first connecting pieces 3111 and the second connecting pieces 3112 in the sealing ring 311 are alternately arranged in sequence and connected end to end.

With continued reference to fig. 10 to 12, it can be understood that the two first connection pieces 301 of the first connector 3111 are disposed at a first angle α, and the two second connection pieces 302 of the second connector 3112 are disposed at a second angle β, so that each sealing ring 311 forms a first fold M1 corresponding to the preset plane Q; and two adjacent sealing rings 311 are connected through two adjacent first connecting sheets 301 and two second connecting sheets 302, so that a second fold line M2 is formed between the two adjacent sealing rings 311. When the sealing film 31 is compressed or stretched, the first and second folds M1 and M2 can play a role in guiding deformation, that is, even if the sealing film 31 can deform according to a preset shape, so that the deformation process of the sealing film 31 is controllable.

In this embodiment, the first connecting piece 301 is in the shape of an isosceles trapezoid, the second connecting piece 302 is in the shape of an isosceles trapezoid, that is, the first connecting edge 3013 is in a straight line shape, and the second connecting edge 3023 is in a straight line shape. In other embodiments, the first connecting edge 3013 may also be curved, and correspondingly, the second connecting edge 3023 is curved.

Referring to fig. 5 and fig. 7, it can be understood that when the first connecting edge 3013 is a straight line and the second connecting edge 3023 is a straight line, the projection of the connection position of the first connecting element 3111 and the second connecting element 3112 on the preset plane Q can be turned off, that is, the first long edge 3011 and the second short edge 3022 can be connected to the corresponding second connecting edge 3023 by the first connecting edge 3013, and the internal stress at the connection position of the first connecting element 3111 and the second connecting element 3112 can be split to the two ends of the first connecting edge 3013 (specifically, the edge L1 and the edge L2 as shown in fig. 7), so that the connection stress is concentrated due to the perpendicular intersection of the first connecting edge 3013 and the second connecting edge 3023, and the connection position of the first connecting edge 3013 and the second connecting edge 3023 is easy to break.

Referring to fig. 10 to 12, in other embodiments, the first connecting edge 3013 may be arc-shaped, the second connecting edge 3023 may be arc-shaped, and the projection of the connecting position of the first connecting element 3111 and the second connecting element 3112 on the preset plane Q may be rounded, that is, the first long edge 3011 and the second short edge 3022 may be connected to the corresponding second connecting edge 3023 by the first connecting edge 3013, and the internal stress at the connecting position of the first connecting element 3111 and the second connecting element 3112 may be split to two ends of the first connecting edge 3013 (specifically, the edge L3 and the edge L4 as shown in fig. 10), so as to avoid the connection stress from being concentrated due to the perpendicular intersection of the first connecting edge 3013 and the second connecting edge 3023, so that the connecting position of the first connecting edge 3013 and the second connecting edge 3023 is easy to break.

In one embodiment, when the first connecting piece 301 is perpendicular to the preset plane Q, the angle between the first connecting edge 3013 and the preset plane Q may be 45 degrees. Correspondingly, when the second connecting piece 302 is perpendicular to the preset plane Q, the angle between the second connecting edge 3023 and the preset plane Q may be 45 °. By the arrangement, the first connecting edge 3013 and the second connecting edge 3023 can be connected, and the first included angle alpha can be changed between 0 degrees and 180 degrees, so that the sealing ring 311 stretches and contracts.

It will be appreciated that when the first connecting piece 301 is perpendicular to the preset plane Q, the angle between the first connecting edge 3013 and the preset plane Q determines the telescopic range of the first angle α, specifically, when the angle between the first connecting edge 3013 and the preset plane Q may be 45 °, the range of the first angle α is the largest, specifically, 0 ° -180 °. When the included angle between the first connecting edge 3013 and the preset plane Q is greater than 45 ° such as 60 °, the range of the first included angle α is smaller than 180 °; still alternatively, when the angle between the first connecting edge 3013 and the preset plane Q is smaller than 45 °, for example 30 °, the range of the first angle α is larger than 0 °, that is, when the first connecting piece 301 is perpendicular to the preset plane Q, the angle between the first connecting edge 3013 and the preset plane Q is larger than 45 ° or smaller than 45 °, the range of the first angle α is smaller than 180 °.

Optionally, the sealing film 31 is made of one of silica gel, polydimethylsiloxane, cyclomethicone, aminosiloxane, polymethylphenylsiloxane and polyether polysiloxane copolymer, so that the sealing film 31 has better elasticity, on one hand, the first included angle α has a larger range, and on the other hand, the sealing ring 311 can be attached to the main body 21, and the sealing performance of the sealing ring 311 is improved.

In addition, the first opening 3010 and the second opening 3020 form a first crease M1 in the seal ring 311; through laminating the setting and meet in proper order two sealing washer 311 for form second fold M2 between two adjacent sealing membrane 31, wherein first fold M1 and second fold M2 can make sealing membrane 31 can take place deformation according to predetermineeing the shape, and the process that makes sealing membrane 31 take place deformation is controllable.
