The embodiment of the present application provides a camera mechanism 100, and the camera mechanism 100 may include a housing 10, a lens 20, at least one set of positioning components 30, and a driving component 40.

The housing 10 may include a top plate 11 and a bottom plate 12 spaced apart in parallel in a thickness direction thereof, and the top plate 11 may be provided with a through-hole 110. The lens 20 includes a main body 21 and a positioning plate 22 connected to an end of the main body 21, wherein the positioning plate 22 is located between the top plate 11 and the bottom plate 12. One end of the main body 21, which is away from the positioning plate 22, is inserted into the through hole 110 and can move in the through hole 110, so that the lens 20 can be ejected from the housing 10 (as shown in fig. 2 and 3) or retracted (as shown in fig. 8 and 9), and further the positioning plate 22 is driven to reciprocate between the top plate 11 and the bottom plate 12. The driving assembly 40 is used for driving the lens 20 to move towards the top plate 11 or the bottom plate 12. The positioning assembly 30 is used to abut the positioning plate 22 against the top plate 11 or the bottom plate 12 to achieve high-precision positioning of the lens 20.

In the related art, the positioning assembly 30 typically employs a resilient structure (not shown), such as a spring, connected to the housing 10 (e.g., the base plate 12) at one end and to the positioning plate 22 at the other end. When the lens 20 is accommodated in the housing 10, the elastic structure is in a compressed state; when lens 20 popped out from casing 10, locating plate 22 is under the elastic action of elastic construction for locating plate 22 can tightly support and lean on roof 11, realizes the high accuracy location of lens 20, guarantees that the optical system of camera has good formation of image effect all the time.

However, the use of spring assisted positioning has the following disadvantages: firstly, the elastic force of the elastic element changes along with the change of the stroke, and is sensitive to the change of the stroke. Specifically, as above, the elastic member is always in a compressed state, and when the lens 20 is accommodated in the housing 10, the elastic force of the elastic member is the largest; when the lens 20 is ejected from the housing 10, the elastic force of the elastic member is minimized. The variation of the spring force has high requirements on the driving assembly 40 for driving the lens 20 to move, and greatly increases the design difficulty of the driving assembly 40. Accordingly, to meet the driving requirements of the elastic member, the size of the driving assembly 40 is not only difficult to be reduced, but also has an increased possibility. Secondly, the elastic member must be used in cooperation with the guiding structure to prevent the elastic member from generating uncontrollable deformation, which occupies more space of the housing 10 and is not favorable for miniaturization of the camera mechanism 100. In addition, the service life of the elastic part is limited, the deformation of the elastic part is usually large, and the repeated use is difficult to avoid reducing the service life of the elastic part again.

Referring to fig. 5 and 11, in the present embodiment, each positioning assembly 30 includes a magnet 31 and a magnetic member 32, one of the magnet 31 or the magnetic member 32 is fixed on the top plate 11 and the bottom plate 12, and the other is fixed on the positioning plate 22, and the magnet 31 and the magnetic member 32 interact (attract or repel each other), in the present embodiment, the magnet 31 and the magnetic member 32 attract each other to make the positioning plate 22 attract to the top plate 11 or attract to the bottom plate 12, so as to achieve high-precision positioning of the lens 20, and ensure that the optical system of the camera mechanism 100 has a good imaging effect all the time. It is understood that in one set of positioning assembly 30, when the magnet 31 is located on the positioning plate 22, the number of the magnetic members 32 is two and located on the top plate 11 and the bottom plate 12, respectively, i.e. the magnet 31 is located between the two sets of the magnetic members 32; when the magnetic members 32 are located on the positioning plate 22, the number of the magnets 31 is two and located on the top plate 11 and the bottom plate 12, respectively, i.e. the magnetic members 32 are located between the two sets of magnets 31.

In other words, the positioning plate 22 is located between the top plate 11 and the bottom plate 12, and due to the positioning assembly 30, the positioning plate 22 can always receive three forces during the movement: a first force F1 towards the top plate 11, a second force F2 towards the bottom plate 12, and a third force F3 provided by the driving assembly 40, wherein the sum of the first force F1, the second force F2, and the third force F3 is zero, i.e., F1+ F2+ F3 is equal to 0. Normally, when the positioning plate 22 is located at a certain position of the top plate 11 and the bottom plate 12, the first force F1 is equal to the second force F2; when the positioning plate 22 is close to the top plate 11, since the distance from the positioning plate 22 to the top plate 11 is less than the distance from the positioning plate 22 to the bottom plate 12, the first acting force F1 is greater than the second acting force F2, and the third acting force F3 is arranged in the same direction as the second acting force F2; when the positioning plate 22 is close to the bottom plate 12, since the distance from the positioning plate 22 to the bottom plate 12 is smaller than the distance from the positioning plate 22 to the bottom plate 12, the first acting force F1 is smaller than the second acting force F2, and the third acting force F3 is arranged in the same direction as the first acting force F1. That is, the driving assembly 40 only needs to apply a small force to drive the lens 20 assembly close to the top plate 11 or the bottom plate 12 no matter where the positioning plate 22 is located between the top plate 11 and the bottom plate 12.

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.

When the positioning plate 22 reaches the top plate 11, the driving assembly 40 stops driving, that is, the third acting force F3 is zero, and at this time, the first acting force F1 is much greater than the second acting force F2, so that the positioning plate 22 abuts against and is adsorbed on the top plate 11, thereby realizing high-precision positioning of the lens 20 and ensuring that the optical system of the camera has a good imaging effect all the time. When the positioning plate 22 reaches the bottom plate 12, the driving assembly 40 stops driving, and the second force F2 is much greater than the first force F1, so that the positioning plate 22 abuts against and adheres to the bottom plate 12, thereby improving the accuracy of the lens 20 reset and the reliability of the lens 20 matching with the housing 10.

In addition, the magnet 31 is usually a permanent magnet, and the magnetism of the magnet 31 hardly changes, so that the service life of the magnet 31 can be ensured. Of course, in other embodiments, the magnet 31 may also be a coil, and the magnetism of the coil increases with the increase of the coil current, and there is no problem of lifetime degradation. In this embodiment, the magnet 31 is a permanent magnet 31, which is small in size and convenient to install, and reduces electrical connection, so that the camera mechanism 100 has a simple structure and good reliability. The magnetic member 32 may be a permanent magnet, a permanent magnet such as a magnet, or a ferromagnetic material such as metallic iron, and is not limited in particular.

Referring to fig. 3 to 5, 10 to 11, and 13 to 15 together, fig. 13 is a schematic perspective view of the top plate and the side plate of the camera mechanism shown in fig. 3, fig. 14 is a schematic perspective view of the top plate and the side plate of fig. 13 at another angle, and fig. 15 is a schematic perspective view of the bottom plate of the camera mechanism shown in fig. 3. Specifically, the housing 10 includes a top plate 11 and a bottom plate 12 arranged in parallel along a thickness direction thereof at an interval, and a side plate 13 connecting the top plate 11 and the bottom plate 12, the top plate 11, the bottom plate 12, and the side plate 13 enclosing to form an accommodating cavity 101, wherein the through hole 110 communicates with the accommodating cavity 101. One end of the main body 21 connected to the positioning plate 22 is received in the receiving cavity 101, and the positioning plate 22 is located between the top plate 11 and the bottom plate 12. The size of the positioning plate 22 is much larger than that of the through hole 110, so that the positioning plate 22 can restrain the main body 21 from being separated from the accommodating cavity 101.

In this embodiment, the top plate 11 and the side plate 13 are integrally formed, and the bottom plate 12 and the side plate 13 are connected by snap-fitting. Specifically, the edge of the bottom plate 12 is provided with a first buckling structure 121, the outer surface of the side plate 13 is provided with a second buckling structure 131, and the first buckling structure 121 and the second buckling structure 131 are in one-to-one correspondence and are buckled and connected, so that the bottom plate 12 and the side plate 13 are fixed.

As shown in fig. 4 or fig. 10, optionally, the first engaging structure 121 is one of the frame and the latch, and the second engaging structure 131 is the other of the frame and the latch, and the frame and the latch can be engaged and connected, so that the bottom plate 12 and the side plate 13 are engaged. In this embodiment, the first engaging structure 121 is a fastening frame extending from the edge of the bottom plate 12, and the second engaging structure 131 is a fastening block located on the outer surface of the side plate 13, so that the bottom plate 12 is engaged with the side plate 13.

In other embodiments, the bottom plate 12 may be integrally formed with the side plate 13, and the top plate 11 is snap-fit connected to the side plate 13, which will not be described in detail herein.

Referring to fig. 4, 5, 14 and 15, the housing 10 further includes a guide post 14 connecting the top plate 11 and the bottom plate 12, and the guide post 14 is received in the receiving cavity 101 and inserted into the positioning plate 22, so that the positioning plate 22 can reciprocate along the guide post 14. Specifically, a first mounting hole 111 is formed in the top plate 11, a second mounting hole 120 is formed in the bottom plate 12, one end of the guide post 14 is received and fixed in the first mounting hole 111, and the other end of the guide post 14 is received and fixed in the second mounting hole 120, so that the guide post 14 is fixed to the top plate 11 and the bottom plate 12.

Alternatively, the bottom plate 12, the top plate 11 and the side plate 13 may be made of a non-magnetic material, such as non-magnetic stainless steel, plastic, wood, ceramic, etc., for reducing the influence of the magnet 31 in the positioning assembly 30 on the optical anti-shake structure and the auto-focusing structure, and improving the reliability of the camera mechanism 100.

Referring to fig. 2, fig. 3, fig. 8, fig. 9 and fig. 16, fig. 16 is a schematic perspective view of a positioning plate in the camera mechanism shown in fig. 3. The lens 20 includes a main body 21 and a positioning plate 22 connected to one end of the main body 21. The cross-sectional dimension of the main body 21 corresponds to the dimension of the through hole 110, so that the main body 21 can reciprocate in the through hole 110, the main body 21 can be ejected from the accommodating cavity 101, and the sealing performance between the main body 21 and the housing 10 can be ensured.

The positioning plate 22 is provided with a guide hole 220, and the guide post 14 penetrates through the guide hole 220, so that the positioning plate 22 reciprocates along the direction of the guide post 14 to restrain the lens 20 from popping or shrinking along a preset direction, and the reliability of popping the lens 20 is improved. The positioning plate 22 is further connected with the driving assembly 40, so that the positioning plate 22 and the main body portion 21 connected to the positioning plate 22 can reciprocate along the direction of the guide post 14 under the driving of the driving assembly 40.

Referring to fig. 5 to 7, the number of the positioning elements 30 is at least one. Magnetic attraction is generated between the magnet 31 and the magnetic piece 32 in each group of positioning assemblies 30, because the magnet 31 or the magnetic piece 32 in each group of positioning assemblies 30 is fixed on the positioning plate 22 at the same time, the relative position between the magnet 31 and the corresponding magnetic piece 32 can be automatically adjusted by each group of positioning assemblies 30, and further the position of the lens 20 relative to the top plate 11 or the bottom plate 12 can be automatically adjusted by the positioning assemblies 30, so that the reliability of abutting connection between the positioning plate 22 and the top plate 11 or the bottom plate 12 can be improved, the magnet 31 and the magnetic piece 32 in each group of positioning assemblies 30 can be accurately aligned, the lens 20 can accurately reach a preset position, and the movement of the lens 20 has higher repetition precision.

Referring to fig. 13 to 16, in the present embodiment, the number of the positioning assemblies 30 is three, and the three positioning assemblies 30 are distributed in a triangle. Wherein, three locating component 30 of group are symmetrical about the optical axis central symmetry of camera lens 20, and that is three locating component 30 of group are roughly equilateral triangle-shaped to be distributed promptly, can reduce the interference between the adjacent locating component 30, ensure the adsorbed reliability of magnet 31 and magnetic part 32 in every locating component 30 of group to because triangle-shaped has stability, can effectively improve locating plate 22 and roof 11 or bottom plate 12 and lean on the reliability of being connected.

In other embodiments, the number of positioning assemblies 30 may also be one, two, four, or more.

In one embodiment, each positioning assembly 30 may include a magnet 31 and two magnetic members 32, wherein the two magnetic members 32 are a first magnetic member 32a and a second magnetic member 32b (shown in fig. 6). The magnet 31 is embedded in the positioning plate 22, the first magnetic member 32a is located on the top plate 11, and the second magnetic member 32b is located on the bottom plate 12. That is, the magnet 31 is located between the first magnetic member 32a and the second magnetic member 32b, since the positioning plate 22 can move back and forth between the top plate 11 and the top plate 11, the magnet 31 can move between the first magnetic member 32a and the second magnetic member 32b, and thus the magnet 31 can be attracted to the first magnetic member 32a or the second magnetic member 32 b.

Alternatively, the line connecting the magnet 31 and the magnetic member 32 in each set of the positioning assembly 30 is parallel to the optical axis of the lens 20. Specifically, in each positioning assembly 30, a line connecting the first magnetic member 32a, the magnet 31 and the second magnetic member 32b is a straight line, and the line connecting the first magnetic member 32a, the magnet 31 and the second magnetic member 32b is parallel to the optical axis of the lens 20. In other words, the magnet 31 may completely overlap with the first magnetic member 32a or the second magnetic member 32b along the optical axis of the lens 20, so as to maximize the attraction force between the magnet 31 and the first magnetic member 32a or the second magnetic member 32b, thereby improving the reliability of the attraction connection between the magnet 31 and the first magnetic member 32a or the second magnetic member 32 b.
