Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

As shown in fig. 1, the embodiment of the present application provides an elastic member 100, which is installed in a camera module and can solve the problem of shake of the camera module during shooting. Elastic member 100 can take place elastic deformation, as shown in fig. 1 and fig. 2, elastic member 100 includes elastic main body 110 and two elastic arms 120, elastic main body 110 is used for being connected with the movable mounting portion 220 that the photosensitive element was installed to the module of making a video recording, two elastic arms 120 are connected with the fixed mounting portion 210 that the module of making a video recording is used for installing camera lens 230, when movable mounting portion 220 moves about relative fixed mounting portion 210, movable mounting portion 220 acts on elastic main body 110, elastic main body 110 and elastic arms 120 can take place deformation, in order to cooperate the activity demand of movable mounting portion 220.

Specifically, as shown in fig. 1 and fig. 2, the elastic body 110 has a central axis a disposed in a direction parallel to an optical axis H of the lens 230 of the camera module, the elastic body 110 includes a first end 111 and a second end 112 disposed oppositely in a direction of the central axis a, the two elastic arms 120 may be both connected to the elastic body 110, the two elastic arms 120 are disposed symmetrically with the central axis a of the elastic body 110 as a symmetry axis, the elastic arms 120 include a plurality of bending units 121 sequentially arranged, and the bending units 121 are at least partially disposed between the first end 111 and the second end 112 of the elastic body 110 in the direction of the central axis a of the elastic body 110.

The elastic arms 120 can be connected to the second end 112 of the elastic body 110, wherein the ends of the two elastic arms 120 far away from the elastic body 110 are both used for being connected to the fixed mounting portion 210 of the camera module, the first end 111 of the elastic body 110 is used for being connected to the movable mounting portion 220 of the camera module, and can drive the photosensitive element mounted on the movable mounting portion 220 to move relative to the lens 230, so that the photosensitive element is deformed to generate an acting force applied to the movable mounting portion 220, and further the photosensitive surface of the photosensitive element is perpendicular to the optical axis H of the lens 230. It can be understood that the photosensitive surface of the photosensitive element needs to be perpendicular to the optical axis H of the lens 230 to satisfy the imaging requirement, and the elastic member 100 can be elastically deformed under the condition that the photosensitive surface of the photosensitive element is maintained to be perpendicular to the optical axis H of the lens 230, so that the photosensitive element can be translated along the direction perpendicular to the optical axis H of the lens 230 or rotated with the optical axis H of the lens 230 as a central axis.

Based on the elastic element 100 provided in the embodiment of the present application, the first end 111 of the elastic body 110 of the elastic element 100 is connected to the movable mounting portion 220, the second end 112 of the elastic body 110 is connected to the two elastic arms 120, and both the two elastic arms 120 are connected to the fixed mounting portion 210, so that a triangular connection structure is formed when the elastic element 100 is connected to the fixed mounting portion 210 and the movable mounting portion 220. The two elastic arms 120 of the elastic element 100 are symmetrically disposed on two sides of the central axis a of the elastic body 110, so that when the movable mounting portion 220 moves relative to the fixed mounting portion 210, the pulling force of the movable mounting portion 220 on the elastic element 100 approaches the central axis a of the elastic body 110, so that the elastic body 110 is not easily turned over around the second end 112 thereof, and the central axis of the elastic body 110 is parallel to the optical axis H of the lens 230, so as to maintain the photosensitive surface of the photosensitive element mounted on the movable mounting portion 220 to be perpendicular to the optical axis H of the lens 230. The parts of the two elastic arms 120 that are not connected to the fixed mounting portion 210 can be deformed, so as to satisfy the requirement that the movable mounting portion 220 can move in the direction perpendicular to the optical axis H of the lens 230 or can rotate with the optical axis H of the lens 230 as the central axis.

In some exemplary embodiments, as shown in fig. 3, the two elastic arms 120 are symmetrically disposed about the central axis a of the elastic body 110, so that the elastic member 100, the movable mounting portion 220 and the fixed mounting portion 210 form an isosceles triangle connection structure, and when the movable mounting portion 220 moves relative to the fixed mounting portion 210, the pulling force of the movable mounting portion 220 on the elastic member 100 coincides with the central axis a of the elastic body 110, so as to further reduce the occurrence of the elastic body 110 flipping about the second end 112 thereof. Further, the two elastic arms 120 are symmetrically arranged, and can be synchronously deformed when being subjected to the driving force transmitted to the elastic body 110 by the movable mounting portion 220, and react on the movable mounting portion 220, so that the movement of the movable mounting portion 220 is more stable.

The elastic arms 120 are of a bending structure that are bent in multiple sections sequentially from the second end 112 of the elastic body 110, and the elastic arms 120 extend in a direction perpendicular to the central axis a of the elastic body 110 to be connected to the fixed mounting portion 210, so that the connection line between the two elastic arms 120 respectively mounted on the fixed mounting portion 210 is perpendicular to the central axis a of the elastic body 110, further the two elastic arms 120 can be deformed synchronously, the pulling force of the movable mounting portion 220 on the elastic member 100 is fully ensured to coincide with the central axis a of the elastic body 110, and the deformation stability of the elastic member 100 is improved.

The multiple bending sections of the elastic arm 120 are arranged to extend the length of the elastic arm 120 in a limited installation space, so as to adjust the flexibility of the elastic arm 120 and meet various deformation requirements. And the two elastic arms 120 are symmetrically arranged, and then the elastic arms 120 are bent, so that when the elastic body 110 moves in a direction perpendicular to the central axis a thereof or deforms and twists around the central axis a thereof, the bent portions of the elastic arms 120 can equally divide the acting force of the elastic body 110 on the elastic arms 120, so that the elastic arms 120 flexibly cooperate with the movement of the elastic body 110.

Specifically, as shown in fig. 3 and 4, the bending unit 121 includes a bending section 1212 and two strip-shaped support sections 1211 connected to both ends of the bending section 1212; the elastic arm 120 further includes a plurality of transition sections 122 arranged in sequence and arranged alternately with the plurality of bending units 121, the transition section 122 located in the middle connects one end of the strip-shaped support section 1211 located between two adjacent bending units 121 and away from the bending section 1212, one of the two transition sections 122 located at two ends of the elastic arm 120 is connected to the second end 112 of the elastic main body 110, and the other is used for being connected to the fixed mounting portion 210; the transition section 122 and the bending section 1212 are both bent with respect to the strip 1211. The length of the elastic arm 120 can be adjusted by adjusting the length of the strip-shaped support section 1211 and/or adjusting the distance between two adjacent strip-shaped support sections 1211 to adjust the length of the transition section 122 and the bending section 1212. The transition section 122 may be configured as a bar shape or a semicircular ring shape with a central angle of 180 degrees, and the bending section 1212 may also be configured as a bar shape or a semicircular ring shape with a central angle of 180 degrees, and the like.

The elastic member 100 may be a flat plate parallel to the optical axis H of the lens, so as to improve the deformation stability of the elastic member 100 when the elastic member deforms. Specifically, when the movable mounting portion 220 moves in a direction perpendicular to the plate surface of the flat plate-shaped elastic member 100, the two elastic arms 120 can be deformed synchronously; when the movable mounting portion 220 moves in a direction parallel to the plate surface of the flat plate-shaped elastic member 100, one of the two elastic arms 120 can deform and contract in the moving direction of the movable mounting portion 220, and the other can deform and expand in the moving direction of the movable mounting portion 220; when the movable mount 220 rotates around the optical axis H of the lens, the two elastic arms 120 are twisted and deformed around the central axis a of the elastic body 110.

The elastic body 110 is in a bar shape, and the length direction of the bar-shaped elastic body 110 is parallel to the optical axis H of the lens, so that the installation space is saved while ensuring that the elastic body 110 can provide the bearing force for the movable installation part 220 in the direction parallel to the optical axis H of the lens. Meanwhile, the elastic main body 110 is arranged in a strip shape, so that the situation that the rigidity is reduced when the elastic main body 110 has structures such as bending and the like can be avoided.

As shown in fig. 4, the strip-shaped support section 1211 may be disposed at an angle to the strip-shaped elastic body 110. Preferably, as shown in fig. 3, two adjacent strip-shaped support sections 1211 are parallel to each other and are disposed parallel to the strip-shaped elastic body 110, so that the strip-shaped support sections 1211 and the strip-shaped elastic body 110 can both provide a bearing force in a direction parallel to the optical axis of the lens, thereby ensuring the deformation stability of the elastic arm 120.

In the direction of the central axis a of the elastic body 110, the bending unit 121 is located between the first end 111 and the second end 112 of the elastic body 110, so as to fully and reasonably plan the structure of the elastic member 100 and reduce the installation space occupied by the elastic member 100. Meanwhile, the ends of the two strip-shaped support sections 1211 adjacent to the elastic body 110, which are far away from the transition section 122, are disposed adjacent to the second end 112 of the elastic body 110, so as to prevent the deformation stability of the elastic member 100 from being affected by an excessively large deformation stroke of the elastic member 100 in a direction parallel to the optical axis H of the lens.

The distance between two adjacent strip-shaped support sections 1211 along a direction perpendicular to the central axis a of the elastic body 110 is denoted as m, and the length of the strip-shaped support section 1211 along a direction parallel to the central axis a of the elastic body 110 is denoted as n, where two parameters of m and n satisfy the following conditional expression: n/m is greater than or equal to 3 and less than or equal to 20, so as to fully expand the length of the elastic arms 120 and save the installation space, and simultaneously, the two elastic arms 120 can bear more acting force in the direction parallel to the optical axis H of the lens, and the rigidity of the elastic member 100 in the direction parallel to the optical axis H of the lens and the flexibility of the elastic member 100 in the direction perpendicular to the optical axis H of the lens can be balanced.

The cross-section of the strip-shaped support section 1211, the cross-section of the bending section 1212, the cross-section of the transition section 122 and the cross-section of the elastic body 110 may all be equal. As shown in fig. 3, in some exemplary embodiments, the cross section of the strip-shaped support section 1211, the cross section of the bending section 1212, and the cross section of the transition section 122 are equal and smaller than the cross section of the elastic body 110, so that the elastic body 110 has sufficient rigidity to be not easily turned over, and the elastic arm 120 obtains the required flexibility, so that the elastic body 110 and the elastic arm 120 can better match the movement of the movable mounting portion 220.

The ends of the two elastic arms 120 far away from the elastic body 110 are spaced apart, so that the ends of the two elastic arms 120 far away from the elastic body 110 are respectively connected to the fixed mounting parts 210. Further, as shown in fig. 3 to 5, the elastic element 100 further includes a first connection portion 130 connected to the first end 111 of the elastic body 110, the first end 111 of the elastic body 110 is connected to the movable mounting portion 220 through the first connection portion 130, the elastic element 100 further includes a second connection portion 140 connected to an end of one of the elastic arms 120 and a third connection portion 150 connected to an end of the other elastic arm 120, and the two elastic arms 120 are connected to the fixed mounting portion 210 through the second connection portion 140 and the third connection portion 150, respectively. It can be understood that, in order to satisfy the deformation requirement, the outer diameter of the elastic arm 120 and the outer diameter of the elastic body 110 are designed to be smaller, which is not favorable for the installation stability of the elastic member 100 when the elastic body 110 is directly connected to the movable installation part 220 and the elastic arm 120 is directly connected to the fixed installation part 210. The first connecting portion 130 and the movable mounting portion 220 of the elastic member 100 are connected, the second connecting portion 140 and the third connecting portion 150 are connected with the fixed mounting portion 210, and the shapes of the first connecting portion 130, the second connecting portion 140 and the third connecting portion 150 are adjusted to increase the connecting area among the structures, so that the mounting stability of the elastic member 100 is effectively improved.

The elastic member 100 is required to be deformable to meet the activity requirement of the movable mounting portion 220, and meanwhile, the elastic member 100 is required to have sufficient structural strength as a connecting member for connecting the fixed mounting portion 210 and the movable mounting portion 220, and based on the above requirement, the elastic member 100 may be a metal elastic member.
