Referring to fig. 3, the camera module 100 in the embodiment of the present application includes a bracket 10, a first camera 30, and a second camera 50. The support 10 is provided with a first installation space 11 and a second installation space 13, the first camera 30 is installed in the first installation space 11, the second camera 50 is installed in the second installation space 13, and the support 10 provides an installation basis for the first camera 30 and the second camera 50.

In the embodiment of the present application, the camera module 100 further includes an elastic frame 40, the elastic frame 40 is at least partially located in the first installation space 11, and the elastic frame 40 can be connected to the bracket 10 or the first camera 30. In the present embodiment, the case that the elastic frame 40 is connected to the bracket 10 is discussed, referring to fig. 4 and 5, the elastic frame 40 is connected to the bracket 10 and elastically supports the first camera 30 in the first installation space 11, and under the action of the elastic frame 40, one side of the first camera 30 departing from the elastic frame 40 supports the bracket 10 against the inner wall surface of the first installation space 11. This elastic frame 40 can be with the firm support of first camera 30 in support 10 to guarantee that the relative position of first camera 30 and support 10 keeps unchangeable, the optical axis of first camera 30 and the contained angle of support 10 are at reasonable within range, make the shooting effect of first camera 30 stable.

The elastic force of the elastic frame 40 can not only ensure that the first camera 30 and the support 10 keep a reasonable relative position in the XY plane, but also prevent the first camera 30 from shaking on the Z axis relative to the support 10 to a certain extent. The XY plane is defined here as: a surface of the electronic device extending in a length direction and a width direction. Further, the XY plane refers to a surface of the mobile terminal extending in a length direction and a width direction. The Z axis is defined here as: the direction perpendicular to the XY plane may be specifically a thickness direction of the mobile terminal.

It can be understood that, when the elastic frame 40 is connected to the first camera 30, the elastic frame 40 elastically supports the inner wall surface of the first installation space 11 of the bracket 10 in the first installation space 11, and under the action of the elastic frame 40, the side of the first camera 30 departing from the elastic frame 40 can also support the inner wall surface of the first installation space 11 of the bracket 10. The action effect is the same as that in the above embodiments, and is not described in detail herein.

A first longitudinal direction and a second longitudinal direction intersecting each other in a plane of view of the first camera 30 are defined. When the lens holder 33 is square, the first length direction is one of the length direction and the width direction of the lens holder 33; the second longitudinal direction is the other of the longitudinal direction and the width direction of the lens holder 33. Specifically, when the outer contour of the mirror base 33 is rectangular, the sizes of the mirror base 33 in the first length direction and the second length direction are not uniform; when the outer contour of the mirror base 33 is square, the mirror base 33 has the same size in the first length direction and the second length direction. The first length direction referred to herein may also be either one of the length direction and the width direction of the mobile terminal in the above-described embodiment; the second longitudinal direction may be the other of the longitudinal direction and the width direction of the mobile terminal in the above-described embodiment.

Within the adjustable range, the included angle between the optical axis of the first camera 30 and the bracket 10 is kept within a reasonable range.

Referring to fig. 6 and 7, a gap formed between the first camera 30 and the first installation space 11 in the second length direction is D1, and a value of D1 may be in the following range: d1 is more than 0mm and less than or equal to 0.08mm, and further D1 can take the value of 0.03mm and less than or equal to D1 and less than or equal to 0.05 mm. Specifically, D1 may be 0.03mm, 0.04mm, or 0.05mm, and D1 may also be a value within any two of the above numerical intervals. If the value of D1 is too small, the fit clearance between the first camera 30 and the first installation space 11 may be too small, and the first camera 30 may be tilted or clamped during the installation of the first camera 30 in the first installation space 11; if the value of D1 is greater than 0.08mm, the fit clearance between the first camera 30 and the first installation space 11 may be too large, and in the process of installing the first camera 30 in the first installation space 11, the first camera 30 shakes in a large range, which may cause the installation position of the first camera 30 to be inaccurate.

The elastic frame 40 is directly clamped on the support 10 through the connecting part 41, so that the installation mode of the elastic frame 40 is simple, and the whole assembly of the camera module 100 is easy to operate.

With reference to fig. 8, 9 and 10, in the above embodiment, the specific structure of the connecting portion 41 may include a first clamping plate 411 and a second clamping plate 413 which are oppositely disposed, and further include an intermediate plate 415 which connects the first clamping plate 411 and the second clamping plate 413, the first clamping plate 411 is located outside the first installation space 11, the second clamping plate 413 is located in the first installation space 11, the abutting portion 43 is connected to a side edge of the intermediate plate 415 which is away from the first clamping plate 411, and the first clamping plate 411 and the second clamping plate 413 jointly clamp the installation wall 12, so that the elastic frame 40 can be not only reliably connected to the installation wall 12, but also be conveniently detached or installed from the installation wall 12.

In the above embodiment, the specific structure of the abutting portion 43 may include two elastic arms 431, the two elastic arms 431 are located in the first installation space 11 and located at two sides of the second clamping plate 413 respectively, one end of each of the two elastic arms 431 is connected to the middle plate 415, and the other end abuts against the first camera 30. The two elastic arms 431 jointly support the first camera 30, and the elastic frame 40 has a stable supporting effect on the first camera 30. It is to be understood that, in the embodiment of the present application, the number of the elastic arms 431 is not limited to two, and may be more or less. The elastic arm 431 is not limited to both sides of the second plate 413, and a structure in which the second plate 413 and the plurality of elastic arms 431 are provided and the second plate 413 and the elastic arms 431 are spaced apart from each other may be used.

With reference to fig. 11 and 12, in the above embodiment, the first clamping plate 411 and the second clamping plate 413 may be further modified, a first locking hole 4111 is formed in the first clamping plate 411, a first protrusion 14 is formed at a corresponding position of the mounting wall 12, and after the elastic frame 40 is mounted on the mounting wall 12, the first protrusion 14 is cooperatively locked in the first locking hole 4111, so that the connection effect between the elastic frame 40 and the mounting wall 12 is more stable and is not easy to loosen. It is understood that the positions of the first protrusion 14 and the first hole 4111 can be interchanged, and the first hole 4111 can be disposed on the first clamping plate 411, and the corresponding first protrusion 14 can be disposed on the mounting wall 12, so as to achieve the technical effects consistent with the above-mentioned embodiments.

The second clamping hole 4131 may also be disposed on the second clamping plate 413, the second protrusion 16 is disposed at a corresponding position of the mounting wall 12, and after the elastic frame 40 is mounted on the mounting wall 12, the second protrusion 16 is engaged with the second clamping hole 4131, so that the connection effect between the elastic frame 40 and the mounting wall 12 is better and more stable. Similarly, the positions of the second protrusion 16 and the second hole 4131 may be interchanged.

The first clip hole 4111 is formed in the first clip 411, and the second clip hole 4131 is also formed in the second clip 413, so that the connection effect between the connection portion 41 of the resilient frame 40 and the mounting wall 12 can be ensured in both directions. So that the elastic frame 40 is firmly connected with the mounting wall 12 and is not easy to loosen.

In the above embodiment, the elastic frame 40 may also be another structure, that is, the abutting portion 43 of the elastic frame 40 is fixed to the mounting wall 12 by a connecting member, which may be a screw, so that the connection between the elastic frame 40 and the bracket 10 is firmer and more reliable. One side of the abutting portion 43 is connected to the connecting portion 41, and the other side elastically abuts against the first camera 30 in the first mounting space 11. The connecting portion 41 and the abutting portion 43 can be both plate-shaped structures, so that the elastic frame 40 is simple to form and easy to connect.

The elastic frame 40 is made of metal materials, so that the abutting force applied to the first camera 30 by the elastic frame 40 is reliable, the first camera 30 can be firmly abutted to the inner wall surface of the first installation space 11 of the support 10, the first camera 30 is ensured not to shake, and the elastic frame 40 has good deformation and rebound effects and long service life.

As can be seen in fig. 2 and 3, the camera module 100 according to the embodiment of the present invention further includes an elastic pad 70, the elastic pad 70 covers a portion of the first camera 30 and a portion of the bracket 10 at an edge of the first installation space 11, and the elastic pad 70 can elastically abut against the first camera 30 and the bracket 10. After first camera 30 wears to locate first installation space 11 on support 10, elastic pad 70 covers a part of first camera 30 and partial support 10, elastic pad 70 can produce elastic deformation under the exogenic action, compress tightly first camera 30 and support 10, can guarantee that first camera 30 and support 10 keep fixed in the Z axle direction, the relative position who makes first camera 30 and support 10 keeps fixed, the contained angle that the optical axis of first camera 30 and support 10 formed keeps fixed, guarantee that the shooting effect of first camera 30 is stable. In the installation process of the camera module 100, the elastic pad 70 is only required to be arranged on the first camera 30 and the support 10, other complex structures are not required, the installation of the first camera 30 and the support 10 can be completed, the structure is simple, the cost is low, and the installation and the operation are convenient.

It can be understood that, when the camera module 100 is applied to an electronic device, the bracket 10 is mounted on the first casing 200 or the second casing 300. When the bracket 10 is mounted on the first housing 200, the second housing 300 is a force applying member for applying an external force to the elastic pad 70; when the stand 10 is mounted on the second housing 300, the first housing 200 is a force applying member for applying an external force to the elastic pad 70. After the first housing 200 is connected to the second housing 300, the camera module 100 can be ensured to be clamped between the first housing 200 and the second housing 300, and the relative position of the first camera 30 and the bracket 10 is ensured to be within a reasonable range.

The elastic pad 70 may be continuously provided in the circumferential direction of the first installation space 11. The elastic pad 70 has a circular ring shape or a square ring shape, which is determined by the shape of the first installation space 11, and is not limited herein. The elastic cushion 70 that sets up in succession along circumference can guarantee that the elastic cushion 70 compresses tightly first camera 30 and support 10 along circumference under the exogenic action for first camera 30 atress is even, promotes the stability that first camera 30 and support 10 are connected, and elastic cushion 70 can directly overlap and locate first camera 30, and the installation is convenient. The continuously arranged elastic pad 70 also has a sealing function on the first camera 30, and can prevent dust from entering the joint of the first camera 30 and the bracket 10.

It should be understood that the elastic pad 70 in the above embodiments may also have a multi-section structure, specifically: the elastic pad 70 includes a plurality of spacers disposed at intervals along the circumference of the first mounting space 11, each spacer covering a part of the first camera 30 and a part of the bracket 10, and the spacers can elastically abut against the first camera 30 and the bracket 10. The shape of the gasket is not strictly required, any shape can be cut, and as long as each gasket can cover and connect the first camera 30 and the support 10 at the position of the gasket, the manufacturing cost of the elastic pad 70 can be saved.

With reference to fig. 13, 14 and 15, the thickness of the elastic pad 70 is defined as H, which may be in the following range: h is more than or equal to 0.25mm and less than or equal to 0.3 mm. Specifically, H may be 0.25mm, 0.26mm, 0.27mm, 0.28mm, 0.29mm, or 0.3 mm. H can also be a value in any two value intervals. If the value of H is less than 0.25mm, the thickness of the elastic pad 70 may be too small, the force applied to the elastic pad 70 by the external force is directly transmitted to the support 10, and the deformation amount of the elastic pad 70 is small, so that the first camera 30 and the support 10 cannot be sufficiently compressed. If the value of H is greater than 0.3mm, the thickness of the elastic pad 70 may be too large, the acting force applied to the elastic pad 70 by the external force cannot be sufficiently transmitted to the first camera 30 and the stand 10, and the pressing force to the first camera 30 is small. When the thickness of the elastic pad 70 is within the range of 0.25mm or more and H or 0.3mm or less, the elastic pad 70 can be sufficiently extruded and deformed by external force, so that the elastic pad 70 sufficiently compresses the first camera 30 and the bracket 10.

The elastic pad 70 in the above embodiment may be further provided with an adhesive layer, and the elastic pad 70 is adhered to the first camera 30 and the stand 10 by the adhesive layer. This adhesive linkage sets up on the surface of cushion 70 towards first camera 30 and support 10, can paste with first camera 30 and support 10 in the installation to can fix a position cushion 70's position, make the in-process cushion 70 that external force pressed and held cushion 70 be difficult for removing, guarantee that the relative position of first camera 30 and support 10 does not change.

A position on the bracket 10 for disposing the elastic pad 70 is defined as a first overlap table 15, the first overlap table 15 being located at a periphery of the first installation space 11; a position on the first camera 30 for disposing the elastic pad 70 is defined as a second landing stage 331, and the second landing stage 331 is located at a periphery of the first camera 30. The first camera 30 is inserted into the first installation space 11 of the bracket 10 such that the first and

second stages

15 and 331 are adjacent to each other. The elastic pad 70 covers at least a part of the first joining table 15 and at least a part of the second joining table 331, and when the elastic pad 70 is abutted by an external force, the elastic pad 70 can be elastically deformed and pressed against the first joining table 15 and the second joining table 331.

Referring back to the embodiment shown in fig. 3, it can be seen that the second engaging platform 331 is disposed on the outer edge of the lens base 33, the lens base 33 is further provided with a second retaining wall 333 protruding from the second engaging platform 331, the second retaining wall 333 is disposed in a ring shape, and the second engaging platform 331 is circumferentially disposed around the outside of the second retaining wall 333. During the installation process, the first camera 30 passes through the first installation space 11 through the lens base 33, and the elastic pad 70 is sleeved outside the second retaining wall 333 to cover at least a portion of the second bridging table 331 and extends outward to cover at least a portion of the first bridging table 15. The second retaining wall 333 plays a role in limiting and fool-proofing for the installation of the elastic pad 70, and improves the installation efficiency of the camera module 100.

As shown in fig. 11, the second engaging platform 331 may be disposed to protrude from the first engaging platform 15, when the elastic pad 70 is subjected to a uniform external force, the pressing force applied to the first engaging platform 15 can ensure the fixed position of the bracket 10, and the pressing force applied to the second engaging platform 331 is greater than the pressing force applied to the first engaging platform 15, so as to further ensure the fixed position of the first camera 30 and the fixed relative position of the first camera 30 and the bracket 10.

In the above embodiment, the height of the second overlapping platform 331 protruding from the first overlapping platform 15 is defined as D2, and the value of D2 may be in the following range: d2 is not less than 0.1mm and not more than 0.15 mm. Specifically, D2 may be 0.1mm, 0.12mm, 0.13mm, 0.14mm, or 0.15 mm. D2 can also be any value within any two of the above numerical ranges. If the value of D2 is less than 0.1mm, the deformation of the elastic pad 70 at the second overlapping table 331 is small under the action of the external force, and the pressure applied to the second overlapping table 331 by the external force through the elastic pad 70 is small, so that it is difficult to ensure that the position of the first camera 30 relative to the bracket 10 does not move during the use. If the value of D2 is greater than 0.15mm, the deformation amount of the elastic pad 70 at the second overlapping table 331 under the action of external force is large, but the deformation amount of the elastic pad 70 is limited, the fall between the first overlapping table 15 and the second overlapping table 331 is large, the pressure transmitted from the elastic pad 70 to the first overlapping table 15 is small, and the support 10 having the first overlapping table 15 may be installed unstably. The value range of D2 is selected to be not less than 0.1mm and not more than 0.15mm of D2, and when the elastic cushion 70 can be pressed and held by external force, the pressure transmitted to the first lapping table 15 and the second lapping table 331 is in a reasonable range, so that when the external force can compress the support 10, the position between the first camera 30 and the support 10 is not changed, and the analytic force of the first camera 30 is ensured.

The thickness of cushion 70 combines second overlap joint platform 331 to bulge in the height of first overlap joint platform 15 for camera module 100 is after the installation is accomplished, and cushion 70 guarantees that first camera 30 and support 10 keep the state of compressing tightly in the reasonable compression range in the exogenic action direction, and relative position does not take place unchangeably.

Because the foam has a series of characteristics of elasticity, light weight, quick pressure-sensitive fixation, convenient use, free bending, ultrathin volume, reliable performance and the like, the elastic pad 70 can be selected as the foam, and the elastic pad 70 can more fully compress the first lapping table 15 and the second lapping table 331 under the action of external force, so that the relative positions of the first camera 30 and the support 10 are further ensured.

It will be appreciated that further modifications may be made to the structure of the bracket 10 to provide a stop for the mounting of the resilient pad 70 by the bracket 10. The first overlap table 15 may be provided as a sunken table, i.e., the first overlap table 15 is recessed in the surface of the bracket 10. The first joining platform 15 is located at the periphery of the first installation space 11, the bracket 10 forms a first retaining wall 17 at one side of the first joining platform 15 away from the first installation space 11, the first retaining wall 17 surrounds the first joining platform 15, and the elastic pad 70 installed behind can be stopped by the first retaining wall 17, so that the elastic pad 70 is prevented from sliding and falling off in the process of applying external force to the elastic pad 70.

The second joining table 15 in the above embodiment may be provided continuously in the circumferential direction of the first camera 30. The second overlapping table 15 which is continuously arranged can be circumferentially compressed by the elastic pad 70, so that the first camera 30 can be ensured to be stressed uniformly along the circumferential direction, and the installation and alignment are more accurate.

Returning again to the embodiment shown in FIG. 3, it can be seen that the second landing stage 331 can also be a multi-stage structure spaced along the periphery of the first camera 30.

The first housing 200 is connected to the second housing 300 to clamp the bracket 10 and the first camera 30 between the first housing 200 and the second housing 300, and the first housing 200 and the second housing 300 may be connected by a snap connection, a screw connection, or other known connection structures, which is not limited herein. The bracket 10 is not required to be fixed with the first housing 200, and is directly fixed by the clamping force between the first housing 200 and the second housing 300, so that the structure is simple, and the installation is convenient. The first housing 200 may further be provided with a structure for limiting the position of the bracket 10, so as to position the mounting of the bracket 10, and further simplify the mounting process.

In the above embodiment, the second housing 300 abuts against a side of the elastic pad 70 opposite to the bracket 10. The second housing 300 abuts against the support 10 through the elastic pad 70, and indirectly transmits the pressure to the second overlapping table 331 of the first camera 30 through the elastic pad 70, so that the second housing 300 can compress the first camera 30, and at the same time, it is ensured that the first camera 30 is not damaged by rigid pressure, and the service life of the first camera 30 is ensured.

The portion of the second housing 300 for abutting against the elastic pad 70 may be an abutting portion 301 protruding from the inner side of the second housing 300, the abutting portion 301 may be a cylindrical protrusion or an arc protrusion matching with the shape of the elastic pad 70, and the abutting portion 301 abuts against the first overlapping table 15 through the elastic pad 70, so as to ensure that the support 10 can be stably installed in the housing.

Specifically, the bracket 10 has a first mounting surface and a second mounting surface that are oppositely disposed, the first mounting space 11 penetrates through the first mounting surface and the second mounting surface, and the second mounting space 13 also penetrates through the first mounting surface and the second mounting surface, so that the first mounting space 11 and the second mounting space 13 are disposed in parallel. The first mounting surface of the bracket 10 abuts against the first housing 200, the first overlapping table 15 is disposed on the second mounting surface, the first camera 30 abuts against the first housing 200 in the region surrounded by the first mounting space 11, the second overlapping table 331 is disposed on the side of the first camera 30 away from the first housing 200, the distance from the second overlapping table 331 to the first housing 200 is greater than the distance from the first overlapping table 15 to the first housing 200, and the elastic pad 70 is abutted by the second housing 300. The elastic pad 70 has a circular inner hole, and since the lens 31 has a circular shape, the elastic pad 70 needs to be sleeved outside the lens 31, so that the elastic pad 70 is provided with a circular inner hole, so that the elastic pad 70 is tightly matched with the first camera 30, the first installation space 11 has a substantially square outline, and the elastic pad 70 has a square outline. The specific shape of the elastic pad 70 is not limited, and is designed to match the shapes of the lens 31, the lens holder 33, and the holder 10.

When the value range of D3 is 0.1mm or more and D3 or more and 0.15mm or less, it is ensured that the pressure applied to the elastic pad 70 by the second housing 300 can stably hold the support 10 and the first camera 30 against the first housing 200. The direction of the height referred to herein is the Z-axis direction defined in the above-described embodiment.
