The first fixing plate 22 is spaced apart from the top plate 11, and one end of the sealing element 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, water vapor, and the like from entering the camera mechanism 100 through the gap between the main body portion 21 and the retractable hole 111.

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

The driving assembly 40 is received and fixed in the receiving 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 out of or retract into the accommodating cavity 101. The imaging assembly 50 is accommodated in the second housing 20 and can extend out of or retract into the accommodating cavity 101 along with the second housing 20 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 oppositely disposed at intervals, and the top plate 11, the bottom plate 12 and the connecting plate 13 enclose a receiving cavity 101 for receiving the second housing 20, the sealing member 30 and the driving assembly 40. Wherein, one end of the driving assembly 40 can be fixed on the bottom plate 12 to connect the driving assembly 40 with the first casing 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 to form a receiving cavity 210. The imaging assembly 50 is received in the receiving cavity 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 receiving cavity 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 consistency and the representation of the appearance of the camera mechanism 100.

Optionally, the body portion 21 may further include a light-transmissive plate 213. The top wall 211 may be provided with a lens 51 hole 2110, the transparent plate 213 may be installed 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 sidewall 212 and the inner annular surface of the first fixing plate 22 is fixed to the sidewall 212. The sealing member 30 is connected to the first fixing plate 22 and the top plate 11 at two ends, respectively, and when the main body 21 extends out of the telescopic hole 111, the first fixing plate 22 can be close to the top plate 11, so that the sealing member 30 is compressed correspondingly. In this embodiment, the first fixing plate 22 is parallel to and spaced apart from the top plate 11, so that the sealing element 30 is uniformly stressed during the compression process, and further the sealing element 30 can be deformed according to the preset shape. In other embodiments, the first fixing plate 22 may be disposed at an angle to the top plate 11, and is not limited herein.

The second housing 20 may further include a second fixing plate 23 fixed on the main body 21, and the second fixing plate 23 is connected to the driving assembly 40 and is capable of extending or retracting the second housing 20 into or out of the receiving cavity 101 under the driving of the driving assembly 40. It is understood that the second fixing plate 23 is disposed on a side of the main body 21 close to the bottom plate 12, and the first fixing plate 22 is disposed on a side of the main body 21 close to the top plate 11, so as to prevent the second fixing plate 23 from affecting the normal operation of the sealing member 30.

The driving assembly 40 may include a driving motor, a lead screw and a lead screw nut, wherein a rotating shaft of the driving motor is fixed and coaxially disposed with the lead screw, so that the driving motor can drive the lead screw to rotate, wherein the lead screw is disposed along a moving direction of the second housing 20. The screw nut is connected with the screw thread and fixed with the second fixing plate 23, so that the driving motor can drive the second shell 20 to extend out of or retract into 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 member 54 is disposed around the lens 51 for automatically focusing the lens 51.

Specifically, one end of the lens 51 away from the elastic element 52 abuts against the top wall 211, and one side of the photosensitive module 53 away from the elastic element 52 abuts against the bottom plate 12. When the second housing 20 retracts into the accommodating cavity 101 from the telescopic hole 111, the top wall 211 of the second housing 20 approaches the bottom plate 12, the lens 51 moves along with the top wall 211 and presses the elastic element 52, so that the elastic element 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 away from the bottom plate 12, and the elastic member 52 provides elastic restoring force so that the lens 51 can move along with the top wall 211.

The photosensitive module 53 may include an optical filter 531, an image sensor 532, and a supporting portion 533, wherein the optical filter 531 and the image sensor 532 are spaced apart from each other along an optical axis of the lens 51, and the supporting portion 533 is located between the optical filter 531 and the image sensor 532 for connecting the optical 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 for filtering infrared light to increase the imaging effect of the camera mechanism 100. The image sensor 532 may be mainly used for receiving light from the lens 51 and converting an optical signal into an electrical signal, so as to meet the imaging requirement 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. Wherein, external light can act on the image sensor 532 through the lens 51 and the filter 531 in sequence. The image sensor 532 may be disposed opposite to the lens 51 in the optical axis direction of the lens 51.

Theoretically, the sealing member 30 clings to the ejection portion of the body portion 21, which is advantageous for improving the sealing performance of the sealing 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 sealing member 30 is tightly attached to the ejection portion of the main body portion 21, the design of the sealing member 30 at the square corner position of the main body portion 21 becomes difficult. Specifically, when the interference of the sealing element 30 at the square corner of the main body 21 is too small, that is, the sealing element 30 is disposed in a gap with the main body 21, the sealing element 30 cannot be sufficiently attached to the main body 21, and the sealing effect is poor; when the interference of the sealing member 30 at the square corner of the main body 21 is too large, that is, the sealing member 30 is disposed in close contact with the main body 21, the interference of the sealing member 30 at the corner is stacked and the friction force is increased, which affects the reliability of the sealing member 30.

In order to solve the above problem, in another related art, the seal member 30 is formed in a substantially cylindrical shape to reduce the interference and friction at the square corner of the body portion 21, but the cylindrical seal member 30 increases the space for use, contrary to the intended miniaturization of the module. Moreover, the sealing element 30 is repeatedly folded in the process of temperature change or reciprocating motion along with the second housing 20, which is prone to problems of flanging, random stacking, abrasion and the like, and affects the reliability and service life of the sealing element 30. In view of this, it is desirable 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 membrane 31 is a hollow cylindrical structure, and the fixing ring 32 can be annular and the inner ring is connected to the sealing membrane 31, so that the sealing membrane 31 and the fixing ring 32 can be sleeved on the main body of the second housing 20 at the same time. One of the fixing rings 32 can be fixed to the top plate 11 by an adhesive material such as glue, and the other fixing ring 32 can be fixed to the first fixing plate 22 by glue, so as to fixedly connect the sealing member 30 to the first casing 10 and the second casing 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 is understood that the fixing ring 32 can be attached to the top plate 11 and the first fixing plate 22 and the sealing member 30 can be connected to the first casing 10 and the second casing 20 by glue or other adhesive materials.

In another embodiment, the material of the fixing ring 32 can be the same as that of the sealing film 31 and can be integrally formed, so that the reliability of the sealing clip can be improved, the production process of the sealing element 30 can be simplified, and the production efficiency of the sealing element 30 can be improved.

Referring to fig. 5 to 6, fig. 5 is a perspective view of a sealing film in the sealing member shown in fig. 4; FIG. 6 is a schematic front view of the sealing membrane 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 311b) 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 sectional view of the sealing film shown in fig. 6 along the direction of section a-a; FIG. 8 is a schematic cross-sectional view of the sealing ring of FIG. 7 taken along the line B-B;

FIG. 9 is a schematic cross-sectional view of the sealing ring of FIG. 7 taken along the direction C-C. Specifically, the sealing ring 311 may include at least two first connecting parts 3111 and at least two second connecting parts 3112, and the first connecting parts 3111 and the second connecting parts 3112 are alternately arranged in sequence and connected end to end. Each first connector 3111 is arranged symmetrically about a predetermined plane Q (i.e. a plane perpendicular to the axis of the sealing ring 311) and has a first opening 3010, and the opening direction of the first opening 3010 faces the inside of the sealing ring 311; each of the second connectors 3112 is disposed symmetrically about the preset plane Q and has a second opening 3020, and the opening direction of the second opening 3020 faces away from the inside of the sealing ring 311.

In one embodiment, each first connector 3111 comprises two first connection plates 301 symmetrically arranged about a predetermined plane Q (i.e. a plane perpendicular to the axis of the sealing ring 311), the two first connection plates 301 are arranged at a first angle α and the opening direction of the first opening 3010 of the first angle α faces the inside of the sealing ring 311; the second connector 3112 includes two second connection pieces 302 symmetrically disposed about the predetermined plane Q, the two second connection pieces 302 are disposed at a second included angle β, and an opening direction of the second opening 3020 of the second included angle β is 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 direction of the cross-section a-a; FIG. 11 is a schematic cross-sectional view of the sealing ring of FIG. 10 taken along the direction D-D; FIG. 12 is a schematic cross-sectional view of the sealing ring in FIG. 10 taken along the direction E-E. In yet another embodiment, each first connector 3111 includes first connection pieces 301 symmetrically disposed about the preset plane Q and having two circular arc shapes, the two first connection pieces 301 enclosing a first opening 3010 having a circular arc shape in cross section; each of the second connector 3112 includes second connection pieces 302 symmetrically disposed about the predetermined plane Q and having two circular arc shapes, and the two second connection pieces 302 surround a second opening 3020 having a circular arc shape in cross section.

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

Referring to fig. 6 to 9, in an embodiment, for example, when the two first connection pieces 301 are disposed at a first included angle α and the two second connection pieces 302 are disposed at a second included angle β, when the sealing ring 311 is in the extreme compression state, the two first connection pieces 301 of the first connection piece 3111 may be disposed in a superposition manner, that is, the first included angle α is disposed at 0 °, and similarly, the two second connection pieces 302 of the second connection piece 3112 are disposed in a superposition manner, and the second included angle β is disposed at 0 °. When the sealing ring 311 is in the extreme tension state, the two first connecting pieces 301 of the second connecting piece 3112 may be in the same plane, i.e. the first angle α is set to 180 °, and similarly, the two second connecting pieces 302 of the second connecting piece 3112 are in the same plane and the second angle β is set to 180 °.

It can be understood that, when the sealing ring 311 is compressed or stretched, because 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 piece 3011 and the second connecting piece 3012 are sequentially and alternately arranged, the first connecting piece 301 can more easily drive the adjacent second connecting piece 302 to move synchronously, so that the first connecting piece 301 and the second connecting piece 302 (i.e. each part of the sealing ring 311) can relatively uniformly bear the squeezing action force, the first connecting piece 301 and the second connecting piece 302 of the sealing ring 311 are prevented from being randomly deformed, and the sealing film 31 is randomly stacked.

In one embodiment, the sealing ring 311 includes two first connecting parts 3111 and two second connecting parts 3112, wherein the two first connecting parts 3111 are spaced apart from each other, and the two second connecting parts 3112 are spaced apart from each other, that is, the connecting portion between the first connecting part 3111 and the second connecting part 3112 has an edge angle. In other embodiments, the sealing ring 311 may further include three first connection members 3111 and three second connection members 3112, to name a few.

Alternatively, the two first connecting pieces 3111 may be disposed in parallel at intervals, and the two second connecting pieces 3112 may be disposed in parallel at intervals and perpendicular to the first connecting pieces 3111, respectively, that is, the projection shape of the sealing ring 311 on the predetermined plane Q is substantially rectangular. Of course, the two second connecting members 3112 may also be disposed in parallel with each other and at an angle to the first connecting member 3111, that is, the projection shape of the sealing ring 311 on the predetermined plane Q is substantially a parallelogram.

In other embodiments, the projection shape of the sealing ring 311 on the predetermined plane Q may also be other quadrangles such as a trapezoid, a square, and the like, and is not limited herein.

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 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 connecting position of the first connecting piece 3111 and the second connecting piece 3112 on the predetermined plane Q may be an inverted angle, that is, the first long edge 3011 and the second short edge 3022 may be connected to the corresponding second connecting edge 3023 through the first connecting edge 3013, and the internal stress at the connecting position of the first connecting piece 3111 and the second connecting piece 3112 can be divided into two ends of the first connecting edge 3013 (specifically, as shown in fig. 7, edge L1 and edge L2), so as to avoid the perpendicular intersection between the first connecting edge 3013 and the second connecting edge 3023 to concentrate the connecting stress, and make the connecting position of the first connecting edge 3013 and the second connecting edge 3023 easy to be damaged.

Referring to fig. 10 to fig. 12, in other embodiments, the first connecting edge 3013 may be an arc, the second connecting edge 3023 may be an arc, and the projection of the connecting position of the first connecting piece 3111 and the second connecting piece 3112 on the predetermined 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 through the first connecting edge 3013, and the internal stress at the connecting position of the first connecting piece 3111 and the second connecting piece 3112 can be distributed to two ends of the first connecting edge 3013 (specifically, as shown in fig. 10, edge L3 and edge L4), so as to avoid the vertical intersection between the first connecting edge 3013 and the second connecting edge 3023 to concentrate the connecting stress, and make the connecting position of the first connecting edge 3013 and the second connecting edge 3023 easy to be damaged.

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

It will be appreciated that the angle between the first connecting edge 3013 and the predetermined plane Q determines the extension and retraction range of the first included angle α when the first connecting piece 301 is perpendicular to the predetermined plane Q, in particular, when the angle between the first connecting edge 3013 and the predetermined plane Q may be 45 °, the range of the first included angle α is maximum, in particular, 0 ° -180 °. When the angle between the first connecting edge 3013 and the predetermined plane Q is greater than 45 °, for example, 60 °, the range of the first angle α is smaller than 180 °; or, when the angle between the first connecting edge 3013 and the predetermined plane Q is smaller than 45 °, for example, 30 °, the range of the first angle α is greater than 0 °, that is, when the first connecting piece 301 is perpendicular to the predetermined plane Q, and the angle between the first connecting edge 3013 and the predetermined plane Q is greater 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 silicone rubber, polydimethylsiloxane, cyclomethicone, aminosiloxane, polymethylphenylsiloxane, and polyether polysiloxane copolymer, so that the sealing film 31 has good elasticity, on one hand, the first included angle α is in a larger range, on the other hand, the sealing ring 311 can be attached to the main body portion 21, and the sealing performance of the sealing ring 311 is improved.
