Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Along with intelligent terminal's popularization, the user has also proposed higher requirement to performances such as focusing, anti-shake of the camera module on the terminal equipment. In the related art, a camera on a terminal device is often an Auto-Focusing (AF) camera, and the AF camera in turn often needs to drive a lens to move through a Voice Coil Motor (VCM).

However, the volume of whole camera module can be increased to voice coil motor itself, influences the spatial layout that piles up of complete machine, and along with the continuous development of image, voice coil motor passes through the mode that magnetism generates electricity, has restricted voice coil motor's load capacity, and the heavier camera lens ability of voice coil motor drive is obstructed, and the position that voice coil motor set up in addition needs to increase X, Y, Z three directions's space, and is very unfavorable to terminal equipment's frivolous design and whole molding.

To solve the above technical problem, the embodiment of the present disclosure provides a driver 100 applied to a camera module of a terminal device. As shown in fig. 1 to 6, the actuator 100 includes a housing 10, a carrier 20, an elastic body 30, and a supporting body 40.

The shell 10 is provided with a through hole, the through hole comprises a light inlet, the lens is arranged in the through hole of the shell 10, the lighting mirror surface of the lens is arranged at a position corresponding to the light inlet, the axial direction of the through hole is parallel to the light inlet direction of the lens, and the light inlet direction is the Z direction in the figure.

The carrier 20 is disposed inside the housing 10, and the carrier 20 is also provided with a through hole penetrating through the carrier 20, and the carrier 20 is used for fixing a lens of the camera module. By fixing the lens on the carrier 20, when the carrier 20 moves along the light inlet direction relative to the housing 10, the carrier 20 drives the lens to move along the light inlet direction relative to the through hole, thereby implementing the auto-focusing function or the anti-shake function of the camera module.

The carrier 20 comprises a first end face 21 and a second end face 22; the first end surface 21 and the second end surface 22 are opposite, and the first end surface 21 and the second end surface 22 are perpendicular to the light entering direction.

The elastic body 30 is provided on the first end surface 21 of the carrier 20, and the elastic body 30 abuts against the inner wall of the housing 10. Specifically, both ends of the elastic body 30 abut against the first end surface 21 of the carrier 20 and the inner wall of the housing 10 near the light entrance, respectively. The supporting body 40 is disposed on the second end surface 22 of the carrier 20, and the carrier 20 is driven to move toward the elastic body 30 by the deformation of the supporting body 40.

Specifically, the direction of the force of the elastic body 30 acting on the carrier 20 is opposite to the direction of the force of the support body 40 acting on the carrier 20, and the elastic body 30 is always in a compressed state.

When the carrier 20 moves towards the light inlet of the through hole along the light inlet direction, the support 40 deforms and drives the carrier 20 to move in the light inlet direction, at this time, the carrier 20 further compresses the elastic body 30, the force of the support 40 acting on the carrier 20 is greater than the force of the elastic body 30 acting on the carrier 20, and therefore, the support 40 pushes the carrier 20 to move towards the light inlet direction, thereby driving the lens to move relative to the housing 10.

When the carrier 20 moves away from the light entrance along the light entrance direction, the shape of the support 40 is restored, the force exerted by the elastic body 30 on the carrier 20 is greater than the force exerted by the support 40 on the carrier 20, and therefore, the elastic body 30 pushes the carrier 20 to move away from the light entrance.

In some embodiments, the elastic body 30 is a compression spring or a leaf spring. In the present embodiment, the elastic body 30 is a spring. The elastic sheet is an elastic sheet in the camera module understood by those skilled in the art, and is not described herein again.

From the above structure, the carrier 20 is driven to move in the light entering direction by the combined action of the deformation of the supporting body 40 and the elastic force of the elastic body 30, so that a voice coil motor structure for driving a lens in the related art is omitted, the space occupied by the voice coil motor is reduced, and the terminal device is favorably designed to be light and thin.

In one embodiment, as shown in fig. 7 and 8, the support 40 includes a deformable membrane layer 41 and a filling medium 42. Wherein, the deformation film layer 41 forms an elastically telescopic sealed cavity; the filling medium 42 is filled in the sealed cavity and changes with the change of the deformation film layer 41. The carrier 20 is driven to move in the light incoming direction relative to the housing 10 by the change of the deformation film layer 41.

Specifically, in some embodiments, the deformable membrane layer 41 is a flexible resin layer or a rubber material layer. The deformable film 41 has sufficient toughness and ductility, and the deformable film 41 can generate a volume change by deformation, so that the movement of the carrier 20 relative to the housing 10 can be driven in the light incoming direction.

In some embodiments, the filling medium 42 is a liquid and the support 40 is provided with a heater 43. The liquid filling medium 42 is selected from sensitive materials that change volume when heated or changed temperature. For example, in some embodiments, the fill medium 42 may be one or more of water, oil, and resin polymer.

The heater 43 is turned on, the filling medium 42 expands when heated, the carrier 20 is driven to move towards the elastic body 30, and the elastic body 30 is compressed; the heater 43 is turned off, the filling medium 42 is shrunk by cooling, and the carrier 20 is moved toward the supporting body 40 by the elasticity of the elastic body 30.

Specifically, the filling medium 42 in the deformable film 41 is heated, so that the liquid filling medium 42 is thermally expanded and has an increased volume, and the increased volume filling medium 42 presses the deformable film 41, so as to expand and deform the deformable film 41. Since the support 40 is disposed in the housing 10 and is circumferentially compressed by the inner wall of the housing 10, the deformable film 41 moves in the light-feeding direction under the action of the thermally expanded filling medium 42, thereby pushing the carrier 20 to move relative to the housing 10.

The heater 43 is turned off, and after the filling medium 42 is cooled or is cooled, the shrinkage volume of the liquid filling medium 42 is reduced, at this time, the deformation film layer 41 starts to shrink, and no thrust is generated on the carrier 20, at this time, under the action of the elastic body 30, the carrier 20 moves in the direction away from the light inlet, so as to drive the lens to move.

Therefore, it is not necessary to provide a voice coil motor, the manufacturing cost of the entire actuator 100 and even the camera module can be reduced, and the focusing range (the moving distance in the light entering direction) is large and the focusing response speed is fast.

In some embodiments, as shown in fig. 4 to 6, the heater 43 is disposed outside the deformable film 41 and on the end surface of the deformable film 41 away from the elastic body 30. The heater 43 is disposed at an end of the support body 40 away from the carrier 20 along the light entering direction, so that the heater 43 does not occupy the space in the XY direction (as shown in fig. 1), thereby reducing the occupied space of the entire camera module.

In another embodiment, the filling medium 42 may be a liquid, and the support body 40 is provided with a hydraulic pump 44; under the action of the hydraulic pump 44, the filling medium 42 is filled into the deformable film 41 or the filling medium 42 is withdrawn from the deformable film 41, so that the deformable film 41 is deformed. In another embodiment, the filling medium 42 is a gas, and the support 40 is provided with an inflator 45; under the action of the inflator 45, the filling medium 42 is filled into the deformation film 41 or the filling medium 42 is withdrawn from the deformation film 41, so that the deformation film 41 is deformed.

Specifically, as shown in fig. 8, the hydraulic pump 44 or the inflator pump 45 is configured to fill the gaseous or liquid filling medium 42 into the sealed cavity of the deformation film layer 41, so that the volume of the deformation film layer 41 changes, and further the deformation film layer 41 expands to increase in volume, and the deformation film layer 41 with the increased volume drives the carrier 20 to move along the light entering direction.

The hydraulic pump 44 or the inflator pump 45 withdraws the gaseous or liquid filling medium 42 in the sealed cavity of the deformation film layer 41, the volume of the deformation film layer 41 changes, the shrinkage volume of the deformation film layer 41 decreases, the deformation film layer 41 with the decreased volume no longer generates a driving force for the carrier 20, and the carrier 20 moves in a direction away from the light inlet under the action of the elastic body 30.

Therefore, the driver 100 of the embodiment of the disclosure has the advantages of low cost, wide focusing range, high control precision and fast focusing response speed through the process of filling or withdrawing the filling medium 42 in the deformation film layer 41 by the hydraulic pump 44 and the inflator pump 45.

In some embodiments, as shown in fig. 1-6, the carrier 20 is ring-shaped. In other embodiments, the supporting body 40 may be provided in plurality and spaced apart along the circumference of the carrier 20; and/or the elastic bodies 30 are provided in plural and spaced apart along the circumference of the carrier 20.

The plurality of support members 40 arranged at intervals may be controlled simultaneously or independently. During synchronous control, the carrier 20 drives the lens to move in a direction parallel to the light entering direction, so that the camera module can be quickly focused. When independently controlled, the temperature of the heater 43 on each support 40 is controlled, the expansion coefficient of the support 40 is controlled, or the amount of water filled or withdrawn by the hydraulic pump 44 is controlled, or the amount of gas filled or withdrawn by the inflator 45 is controlled, so as to control the amount of expansion or contraction of the deformable film 41 of each support 40, so that the carrier 20 or the lens can be shifted relative to the light-entering direction, thereby realizing the optical anti-shake function.

Based on the same concept, the embodiment of the present disclosure provides a camera module, which includes the above-mentioned driver 100 and a lens, where the lens is fixed in the through hole of the carrier 20, and the driver 100 drives the lens to move relative to the housing 10 along the light entering direction. The automatic focusing function of the camera module is realized. The detailed structural features of the lens are within the understanding of those skilled in the art, and are not described herein.

Based on the same conception, the embodiment of the disclosure provides a terminal device, which comprises the camera module. The terminal device can be a mobile phone, a computer, a game console, a tablet device, a medical device, a fitness device, a watch, a bracelet and other wearable devices.
