In fact, they are used to reflect the relative position and/or direction between various portions of the object.
The driving device of the present embodiment is disposed in the camera device and is used for driving the lens to move along the optical axis, thereby playing a role of focusing.
The base 2 has a square shape when viewed from the axial direction, and the square shape of the housing 1 corresponds to the square shape of the base 2. Side walls 125 protruded forward are respectively provided on the front side surface of the base 2 at positions corresponding to the locking grooves 114. Locking members 124 are provided so as to protrude on the surface facing the outside of the side walls 125 corresponding to the shape of the locking grooves 114. That is, the locking members 124 are provided by three on each side and all extend from the front end of the side wall 125 toward the rear side in the axial direction. In addition, the base 2 has a surrounding structure 22 provided substantially all around the periphery thereof.
In the process of assembling the driving device, the housing 1 is combined to the base 2 from the front side. At this time, since the locking grooves 114 and the locking members 124 extend in the same axial direction, the housing 1 can be smoothly combined with the base 2. Usually, the inner side surface of the outer peripheral side wall 16 and the surrounding structure 22 are adhered and fixed, and the locking grooves 114 and the locking members 124 are further adhered and fixed. In the assembled state of the driving device, the locking members 124 are locked in the locking grooves 114, thereby further improving the firmness of the assembled housing 1 and the base 2.
Thus, in the assembled state, the locking members 124 are locked in the locking grooves 114, so that the housing 1 and the base 2 are fixed by the locking of the locking members 124 and the locking grooves 114, thereby improving the firmness between the housing 1 and the base 2 during fixing.
Although one Example of the present embodiment is as described above, in other Examples of the present embodiment, the housing 1 of the driving device may have more details in many aspects compared with the above-mentioned Example, and at least a part of these details may have various variations. At least a part of these details and variations will be described below with some Examples.
The coil 7 is provided by being wound with the axial direction of the housing 1 as a winding axis so as to surround the outer peripheral side of the lens support 5 and generates a magnetic circuit on the outer circumferential surface of the lens support 5 after being energized. The magnet 6 is disposed on the inner peripheral side of the housing 1. As shown in
In the present embodiment, the rear side end surface of the outer peripheral side wall 16 of the housing 1 is preferably adhered to a front side surface adjacent to the outer peripheral surface of the surrounding structure 22 on the base 2, thereby further improving the firmness of the adhesion between the housing 1 and the base 2.
In the present embodiment, when assembling, it is preferable that an adhesive may also be applied on the contact surfaces of the locking members 124 and the locking grooves 114, so as to adhere the locking members 124 and the locking grooves 114 to further enhance the assembly firmness.
In the present embodiment, it is preferable that the side wall 125 is a part of the surrounding structure 22 of the base 2, so that the base 2 can form the surrounding structure 22 and the side wall 125 by integral molding.
As shown in
In the present embodiment, the housing 1 has a rectangular shape, and the magnets 6 are provided at the four corner portions 10 of the housing 1, so that the size of the housing can be reduced while ensuring the internal space of the housing 1. In some other embodiments different from that shown in the figure, the housing 1 may also have other suitable polygonal shapes.
In the present embodiment, each of the corner portions 10 of the housing 1 includes a step portion 11 recessed downward in the thickness direction of the housing 1 and formed in a stepped shape. The step portion 11 includes a step horizontal surface 110 extending in a direction intersecting with the axial direction of the housing 1. Correspondingly, the base 2 is provided with protruding tables 21 protruding from four corners of the base 2 toward the front side thereof. In the assembled state, the housing 1 is abutted to the base 2. At this time, the table surface 210 of the protruding table 21 is adhered to the rear side surface of the step horizontal surface 110 (that is, the surface opposite to the table surface), thereby further improving the firmness of the connection of the housing 1 and the base 2.
In the present embodiment, the protruding tables 21 are a part of the surrounding structure 22 of the base 2, so that the base 2 can be manufactured by integral molding.
Further, as shown in
In one embodiment of the driving device, the driving device is disposed in the camera device and the lens 8 is the lens of the camera device.
In an embodiment of the camera device, the aforementioned camera device is disposed in an electronic device such as a notebook computer or a mobile phone.
