[0033] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0034] like Figures 1 to 7 As shown, the anti-shake motor 100 of the embodiment of the present disclosure includes a housing 1, a circuit board 2 and an anti-shake component 3, the housing 1 includes a base 11 and a cover 12, the cover 12 is connected to the base 11 and surrounds a mounting cavity 13. The circuit board 2 is connected to the base 11. The circuit board 2 includes a board body 21 and a connecting portion 22, and the board body 21 is arranged in the mounting cavity 13. The connecting portion 22 is arranged outside the mounting cavity 13, and the connecting portion 22 is provided with a first exposed copper area 221. Anti-shake component 3 The anti-shake component 3 is arranged in the mounting cavity 13 and is electrically connected to the board body 21.

[0035] The anti-shake motor 100 of the disclosed embodiment is configured such that the circuit board 2 includes a board body 21 and a connection portion 22, the board body 21 and the anti-shake component 3 are disposed in the mounting cavity 13, and the anti-shake component 3 is electrically connected to the board body 21, so as to realize the electrical connection between the anti-shake component 3 and the circuit board 2; the connection portion 22 is disposed outside the mounting cavity 13, and a first copper-exposed area 221 is disposed on the connection portion 22, and the electrical connection between the anti-shake motor 100 and the power supply can be realized by using the first copper-exposed area 221. Thus, the connection portion 22 of the circuit board 2 realizes the pin function of the anti-shake motor 100, that is, the pins of the anti-shake motor 100 are integrated on the circuit board 2, so that the structure of the anti-shake motor 100 can be simplified, the manufacturing process of the anti-shake motor 100 can be simplified, and the manufacturing cost of the anti-shake motor 100 can be reduced.

[0036] Therefore, the anti-shake motor 100 according to the embodiment of the present disclosure has the advantages of low manufacturing cost and the like.

[0037] The first copper exposed area 221 and the power source may be electrically connected via a PCB (Printed Circuit Board), that is, the first copper exposed area 221 and the PCB are electrically connected, and the PCB and the power source are electrically connected.

[0038] Optionally, the circuit board 2 is a FPC (Flexible Printed Circuit).

[0039] By using the circuit board 2 as a flexible circuit board, the thickness of the circuit board 2 can be reduced, and the volume of the anti-shake motor 100 can be reduced.

[0040] Optionally, the circuit board 2 is bonded to the base 11 .

[0041] For example, the plate body 21 and the surface of the base 11 are bonded by colloid.

[0042] By bonding the circuit board 2 to the base 11 , the connection between the circuit board 2 and the base 11 is facilitated, which is beneficial to further reduce the manufacturing cost of the anti-shake motor 100 .

[0043] In some embodiments, Figure 2 , Figure 6 and Figure 7 As shown, the connecting portion 22 is in a sheet shape, intersecting with the plate body 21 , and disposed on a side of the plate body 21 facing away from the cover body 12 .

[0044] For example, the connection portion 22 is disposed perpendicular to the plate body 21 .

[0045] By arranging the connection portion 22 and the plate body 21 to intersect, compared with arranging the connection portion 22 and the plate body 21 in the same plane, it is beneficial to improve the structural compactness of the circuit board 2 and reduce the volume of the anti-shake motor 100.

[0046] Alternatively, if Figure 2 As shown, the base 11 includes a top surface 111 and a side surface 112. The top surface 111 is disposed toward the cover body 12, and the side surface 112 intersects with the top surface 111. The plate body 21 is in contact with the top surface 111, and the connecting portion 22 is in contact with the side surface 112.

[0047] For example, the side surface 112 is disposed perpendicular to the top surface 111 , the connection portion 22 is disposed perpendicular to the plate body 21 , the plate body 21 is parallel to and in contact with the top surface 111 , and the connection portion 22 is parallel to and in contact with the side surface 112 .

[0048] By fitting and connecting the plate body 21 to the top surface 111 and the connecting portion 22 to the side surface 112, on the one hand, the connection area between the circuit board 2 and the base 11 can be increased, and the connection reliability between the circuit board 2 and the base 11 can be improved; on the other hand, when the circuit board 2 is a flexible circuit board, the base 11 can be used to support the plate body 21 and the connecting portion 22 at the same time, avoiding bending and deformation of the circuit board 2, thereby facilitating the installation and fixation of the anti-shake motor 100.

[0049] Alternatively, if Figure 2 , Figure 6 and Figure 7 As shown, there are multiple first copper exposed areas 221 , and the multiple first copper exposed areas 221 are arranged at intervals.

[0050] By providing a plurality of first copper exposed areas 221 , it is beneficial to increase the connection area of ​​the connection portion 22 , thereby improving the electrical connection reliability of the anti-shake motor 100 .

[0051] In some embodiments, Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, the anti-shake component 3 includes an anti-shake coil 31, the board 21 is provided with a second copper-exposed area 211, and the anti-shake coil 31 is provided on the board 21 and electrically connected to the second copper-exposed area 211. The anti-shake coil 31 refers to: a coil of the anti-shake motor 100 for realizing the anti-shake function.

[0052] For example, the anti-shake coil 31 is welded to the second copper exposed area 211 to achieve mechanical connection between the anti-shake coil 31 and the board body 21 as well as electrical connection between the anti-shake coil 31 and the board body 21 .

[0053] By electrically connecting the anti-shake coil 31 to the second copper exposed area 211, the electrical connection between the anti-shake coil 31 and the circuit board 2 is achieved. By setting the anti-shake coil 31 on the board body 21, the anti-shake coil 31 is integrated on the circuit board 2. Therefore, when manufacturing the anti-shake motor 100, the anti-shake coil 31 can be connected to the circuit board 2 first, so that the anti-shake coil 31 and the circuit board 2 form a circuit board assembly, and then the circuit board assembly is connected to the base 11, thereby improving the production efficiency of the anti-shake motor 100 and further reducing the manufacturing cost of the anti-shake motor 100.

[0054] Alternatively, if Figure 4 , Figure 6 and Figure 7 As shown, the anti-shake assembly 3 further includes a focus coil 32, which is disposed on the side of the plate body 21 facing away from the base 11. The anti-shake motor 100 further includes a suspension wire 4, and the plate body 21 is provided with a third copper-exposed area 212, and the suspension wire 4 is electrically connected to the focus coil 32 and the third copper-exposed area 212. The focus coil 32 refers to: a coil of the anti-shake motor 100 for realizing the focus function.

[0055] For example, Figure 5 As shown, the suspension wire 4 is welded to the third copper exposed area 212 via a first welding point 51 , and the suspension wire 4 is welded to the focusing coil 32 via a second welding point 52 .

[0056] By electrically connecting the suspension wire 4 to the focus coil 32 and the third copper exposed area 212 , the electrical connection between the focus coil 32 and the circuit board 2 is facilitated, which is beneficial to further improve the assembly efficiency of the anti-shake motor 100 and reduce the manufacturing cost of the anti-shake motor 100 .

[0057] It is understandable that the suspension wire 4 not only serves to electrically connect the focus coil 32 and the circuit board 2 , but also serves to support the anti-shake assembly 3 , and the connection stability of the suspension wire 4 needs to be ensured.

[0058] Alternatively, if Figure 6 As shown, the circuit board 2 is provided with a first through hole 23 , the base 11 is provided with a second through hole 113 , and the suspension wire 4 passes through the first through hole 23 and the second through hole 113 and is connected to the base 11 .

[0059] For example, Figure 5 As shown, the suspension wire 4 and the base 11 are heat-riveted via the heat-riveting points 53 .

[0060] By connecting the suspension wire 4 to the base 11 , the suspension wire 4 and the circuit board 2 can be prevented from being separated when subjected to a large force, thereby improving the connection stability between the suspension wire 4 and the circuit board 2 and thus improving the reliability of the anti-shake motor 100 .

[0061] Optionally, the anti-shake component 3 includes a Hall element 33, the board 21 is provided with a fourth copper-exposed area 213, and the Hall element 33 is provided on the board 21 and electrically connected to the fourth copper-exposed area 213. The Hall element 33 may be a Hall sensor.

[0062] For example, the Hall element 33 is welded to the fourth copper exposed area 213 to achieve mechanical and electrical connection between the Hall element 33 and the circuit board 2 .

[0063] By electrically connecting the Hall element 33 to the fourth copper exposed area 213, the Hall element 33 is electrically connected to the circuit board 2. By arranging the Hall element 33 on the board body 21, the Hall element 33 is integrated on the circuit board 2. Therefore, when manufacturing the anti-shake motor 100, the Hall element 33 can be first connected to the circuit board 2, so that the Hall element 33 and the circuit board 2 form a circuit board assembly, and then the circuit board assembly is connected to the base 11, thereby improving the production efficiency of the anti-shake motor 100 and further reducing the manufacturing cost of the anti-shake motor 100.

[0064] The anti-shake motor 100 of the disclosed embodiment integrates the pins, the anti-shake coil 31 and the Hall element 33 directly with the circuit board 2 as a whole, which not only avoids embedding a steel sheet in the base 11, but also greatly simplifies the assembly process of the anti-shake motor 100, thereby reducing the manufacturing cost of the anti-shake motor 100. In addition, the base 11 of the anti-shake motor 100 is separated from the circuit, so that when the base 11 has a problem and needs to be replaced, only the base 11 can be replaced, and the circuit board 2 can be reused, thereby reducing the maintenance cost of the anti-shake motor 100. When the anti-shake motor 100 is electrically connected to the power supply, the first copper-exposed area 221 of the connecting portion 22 is welded to the PCB.

[0065] The camera module of the embodiment of the present disclosure includes an anti-shake motor 100 and a lens, wherein the anti-shake motor 100 is the anti-shake motor 100 described in any of the above embodiments, and the lens is connected to the anti-shake motor 100. The anti-shake function of the lens can be realized by using the anti-shake motor 100.

[0066] Since the manufacturing cost of the anti-shake motor 100 of the embodiment of the present disclosure is low, the camera module of the embodiment of the present disclosure has the advantages of low cost, etc.

[0067] The terminal device of the embodiment of the present disclosure includes the camera module described in any of the above embodiments, wherein the terminal device can be a mobile phone, a tablet computer, a laptop computer, etc.
