[0034] It should be noted that, when used, the terms up, down, left, right, front, back, top, bottom, positive, negative, clockwise and counterclockwise in the following description are used only for convenience and do not imply any specific fixed direction. In fact, they are used to reflect the relative position and / or direction between various parts of an object.

[0035] The driving device is arranged in the photographing device and is used to drive the lens to move along the optical axis, thereby achieving a zooming effect. Figure 1 A schematic diagram of an exploded view of an embodiment of a driving device is shown, wherein the driving device comprises a shell 1 and a base 2 arranged at the rear side of the shell 1 for supporting the shell 1, and a front spring piece 3, a rear spring piece 4, a lens carrier 5, a magnet 6 and a coil 7 are respectively arranged in the shell 1.

[0036] Figure 2 is a schematic diagram of the base 2 in the driving device, Figure 31 is a three-dimensional schematic diagram of the housing 1 in the driving device. The housing 1 includes an outer peripheral side wall 16 and a top wall 17 connected to the front side of the outer peripheral side wall 16. An opening 18 is provided on the top wall 17 to allow light to pass through the camera device. A card slot 114 is provided on the inner side of the outer peripheral side wall 16 of the housing 1. Correspondingly, side walls 125 are protrudingly provided on the front side of the base 2 at positions corresponding to the card slot 114. A snap key 124 is provided on the side wall 125 in a shape corresponding to the card slot 114. When the driving device is assembled, the snap key 124 is snapped into the card slot 114, thereby further enhancing the firmness of the housing 1 and the base 2 after assembly.

[0037] In the assembled state, the snap key 124 is snapped into the snap slot 114 , so that the shell 1 and the base 2 are fixed by the snap action of the snap key 124 and the snap slot 114 , thereby increasing the firmness between the shell 1 and the base 2 when fixed.

[0038] Although one embodiment of the drive device is described above, in other embodiments of the drive device, the housing 1 of the drive device may have more details in many aspects relative to the above embodiment, and at least a part of these details may have various changes. At least a part of these details and changes will be described below with some embodiments.

[0039] Figure 4 For a cross-sectional view of the drive unit, see Figure 4 , other components of the driving device are described below. The lens carrier 5 is arranged in the housing 1, and is used to support the lens 8. The front spring piece 3 is arranged between the lens carrier 5 and the housing 1, and the rear spring piece 4 is arranged between the lens carrier 5 and the base 2. The front spring piece 3 and the rear spring piece 4 elastically hold the lens carrier 5 in the housing 1, and allow the lens carrier 5 to move along the optical axis direction (i.e., the axial direction of the housing 1) when subjected to external force. Among them, in an embodiment different from the figure, the front spring piece 3 and the rear spring piece 4 are arranged on at least one side of the front side and the rear side of the lens carrier 5, and can also play the role of elastically holding the lens carrier 5.

[0040] The coil 7 is disposed around the outer circumference of the lens carrier 5, and generates a circuit on the outer circumference of the lens carrier 5 after power is supplied. The magnet 6 is disposed on the inner circumference of the housing 1. Figure 3 as well as Figure 4 As shown, the magnet 6 is adsorbed on the housing 1 through the side surface 60 of the magnet 6, and is separated from the coil 7 by a distance. When current is passed through the coil, the energized coil 7 is acted upon by the external magnetic field generated by the magnet 6 to generate an Ampere force, thereby driving the lens carrier and the lens to move along the optical axis direction (i.e., the axial direction of the housing 1).

[0041] Figure 5This is a three-dimensional schematic diagram of the drive device in the assembled state. Please continue to refer to Figure 1 and Figure 5 , a winding post 51 is provided on the outer peripheral side of the lens carrier 5, and the winding post extends in the radial direction of the lens carrier, and is used for wiring in the drive device. On the top surface of the base 2, there is a surrounding structure 22 protruding upward from the bottom surface and arranged around the base 2. The surrounding structure 22 can be a convex rib arranged around the base 2. The surrounding structure 22 has a disconnected section to form an avoidance gap 20 on the base 2. Correspondingly, an avoidance opening 160 is provided at the position of the shell 1 corresponding to the avoidance gap 20. When the shell 1 and the base 2 are assembled, the avoidance opening 160 is connected and communicated with the avoidance gap 20 to form an avoidance channel 100 on the shell 1. Combined Figures 1 to 5 It can be seen that in the assembled state, the housing 1 is connected to the base 2, and the lens carrier 5 is accommodated in the housing 1. At this time, the avoidance channel 100 provides an accommodation space for the winding post 51 in the lens carrier 5 on the housing 1. Since the winding post 51 in the lens carrier 5 is directly placed in the avoidance channel 100 of the housing 1 in the assembled state, there is no need to reserve space inside the housing for placing the winding post 51, thereby reducing the size of the housing.

[0042] In one embodiment of the driving device, the rear end surface of the outer peripheral side wall 16 of the shell 1 is bonded to the front side surface adjacent to the outer peripheral surface of the surrounding structure 22 on the base 2, thereby further improving the bonding strength between the shell 1 and the base 2.

[0043] In one embodiment of the driving device, during assembly, adhesive may be applied to the interface between the snap key 124 and the slot 114 to glue the snap key 124 and the slot 114 together to further enhance assembly firmness.

[0044] In one embodiment of the driving device, 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 in an integrally formed manner.

[0045] Please see Figure 3 In one embodiment of the driving device, the shell 1 is made of a magnetic conductive material, and the magnet 6 is adsorbed on the inner circumference of the shell 1. The shell 1 also includes an inner circumferential side wall 14, which extends from a top opening 18 on the inner circumferential side of the top wall 17 toward the rear side, and the inner circumferential side wall 14 is configured to correspond to each second step wall 131 and be opposite to each other in a direction orthogonal to the axis of the shell 1. Specifically, the inner circumferential side wall 14 is arranged on the outer side of each magnet 6 during assembly, and the area where the inner circumferential side wall 14 is located becomes an effective magnetic field area through the magnetic conductive effect of the magnet 6. Figure 5It can be seen that the coil 7 is arranged between the magnet 6 and the inner side wall 14, and a magnetic circuit is formed between the inner side wall 14 and the side of the magnet 6 opposite to the coil. When current is passed through the coil 7, the magnetic circuit can generate Ampere force on the energized coil, thereby driving the coil 7 to move.

[0046] In one embodiment of the driving device, the shell 1 is a rectangular body, and the magnets 6 are arranged at the four corners 10 of the shell 1, so that the size of the shell can be reduced while ensuring the internal space of the shell. In some other embodiments different from those shown in the figure, the shell 1 can also be other suitable polygonal shapes.

[0047] In one embodiment of the driving device, each corner 10 of the housing 1 includes a step portion 11 that is recessed downward along the thickness direction of the housing 1 and forms a step shape. The step portion 11 includes a step plane 110 extending along the intersecting direction of the axis direction of the housing 1. Correspondingly, the base 2 has a boss 21 that protrudes from the base 2 to the front side thereof. In the assembled state, the housing 1 is connected to the base 2, and at this time, the table 210 of the boss 21 is bonded to the rear side surface of the step plane 110 (i.e., the side opposite to the table surface), thereby further enhancing the connection firmness between the housing 1 and the base 2.

[0048] In one embodiment, the boss 21 is a part of the surrounding structure 22 of the base 2, so that the base 2 can be manufactured in an integrally formed manner.

[0049] Please continue to see Figure 1 In one embodiment of the driving device, a coil slot 50 is provided in the middle of the outer peripheral side of the lens carrier 5, and the coil 7 is surrounded and arranged in the coil slot 50 so as to be fixed on the lens carrier 5. The winding post 51 is arranged below the coil slot 50 to correspond to the position of the avoidance channel 100 in the shell 1.

[0050] In one embodiment of the driving device, the driving device is arranged in a photographing device, and the lens 8 is the lens of the photographing device.

[0051] In one embodiment of the camera device, the camera device is disposed in an electronic device such as a notebook computer, a mobile phone, etc.
