The VCM primarily consists of a bracket, magnet, upper and lower springs, base, coil, and housing, and its performance plays a crucial role in determining camera quality. Currently, the base is embedded within the bracket, connected to the frame via barbed posts and secured with glue.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to diagrams and specific embodiments.
[0025] Example 1: Figures 1 to 7 As shown, the present invention proposes an anti-falling structure for an embedded motor housing, which includes a coil 1, a magnet 2, a housing 3, an upper spring piece 4 and a lower spring piece 5; the magnet 2 is sleeved on the outside of the coil 1, the magnet 2 and the coil 1 are arranged inside the housing 3, and the upper spring piece 4 and the lower spring piece 5 are respectively arranged on both side ends of the housing 3; an integrated base 6 is also provided on the outside of the lower spring piece 5, and a frame 7 is also provided on the outside of the upper spring piece 4, and the inner extension end of the frame 7 is embedded in the inner extension end of the integrated base 6.
[0026] The inner end surfaces of the integrated base 6 and the frame 7 are provided with a plurality of mounting grooves for mounting the housing 3 and the coil 1 .
[0027] By adopting the above technical solution, by making the bracket and base in the prior art into an integrated base, the present invention can omit the installation of the bracket during the installation process, thereby reducing the assembly process steps and improving the stability of the motor performance; by adopting the above technical solution, by using an embedded installation between the integrated base and the frame instead of the original hook-type installation, the installation of the integrated base and the frame is more convenient and the strength after assembly is improved.
[0028] The present invention is further configured as follows: the inner end of the integrated base 6 has four groups of first limiting structures, and the four groups of first limiting structures are respectively located at the four corners of the integrated base 6, and the inner extension end of the frame 7 is engaged with the first limiting structure at the inner end of the integrated base 6.
[0029] The present invention is further configured as follows: the inner end of the frame 7 has four groups of second limiting structures, and the four groups of second limiting structures are respectively located at the four corners of the frame 7, and the second limiting structures on the inner side of the frame 7 are embedded with the first limiting structures on the inner end of the integrated base 6.
[0030] The first limiting structure and the integrated base are an integrated structure, and the second limiting structure and the frame are an integrated structure.
[0031] By adopting the above technical solution, by forming a first limiting structure on the integrated base and a second limiting structure on the frame, and then embedding the first limiting structure and the second limiting structure, the motor can be easily installed.
[0032] The present invention is further configured as follows: the first limiting structure includes a first limiting block 61, on which a first card slot 611 and a second card slot 612 are provided; the second limiting structure includes a second limiting block 71, on the inner side of which a third card slot 711 and a fourth card slot 712 are provided; the first limiting block 61 is adapted to the third card slot 711 and the fourth card slot 712, and the second limiting block 71 is adapted to the first card slot 611 and the second card slot 612.
[0033] The first limiting block 61 is divided into a first mounting block and a second mounting block by the second slot 612. The first slot is opened on the upper side of the first mounting block. The first mounting block is adapted to the third slot, and the second mounting block is adapted to the fourth slot. The four groups of first mounting structures are centrally symmetrical structures, and the four groups of second mounting structures are also centrally symmetrical structures.
[0034] A third slot is provided on the second mounting block in one of the groups of first limiting structures. The third slot is used to identify the installation direction between the integrated base and the frame. The provision of the third slot also facilitates the assembler to identify the installation direction of the coil, magnet and shell, thereby enabling easier assembly.
[0035] The inner end surface of the integrated base has a plurality of protrusions, and the plurality of protrusions are used to position and install the lower spring piece; the upper spring piece is clamped between the four groups of second limit blocks.
[0036] By adopting the above technical solution, the first limit block 61 is clamped with the third card slot 711 and the fourth card slot 712, and the second limit block 71 is clamped with the first card slot 611 and the second card slot 612, so that the assembly structure between the integrated base and the frame is tighter and more reliable.
[0037] The present invention is further configured as follows: the inner sides of the first limiting block 61 and the second limiting block 71 are arc-shaped surfaces, and the arc-shaped surfaces are in contact with the outer wall of the housing 3 .
[0038] By adopting the above technical solution and setting the arc-shaped surface, the first limiting structure and the second limiting structure will not affect the installation of the shell, and can limit the shell.
[0039] The present invention is further configured as follows: the pins on the outer side of the lower elastic piece 5 are clamped in the first clamping slot 611 .
[0040] By adopting the above technical solution, due to the setting of the first limiting mechanism on the integrated base, the installation of the lower spring piece is not very quick; the first card slot can not only be connected with the second limiting block, but the first card slot can also be used to place the pins of the lower spring piece, making it easier to install the lower spring piece, and then position it through the protrusions.
[0041] The present invention further provides a voice coil motor, comprising the above-mentioned interlocking motor housing anti-falling structure.
[0042] The present invention also provides an electronic device, comprising the voice coil motor as described above.
[0043] The difference between the second embodiment and the first embodiment is that the original bracket is removed and the original base is made into the shape of the base in the first embodiment.
[0044] The third embodiment differs from the first embodiment in that the original base is removed and the original bracket is made into the shape of the base in the first embodiment.
[0045] The above embodiments are only for illustrating the technical concept and features of the present invention. Its purpose is to enable technicians in this field to understand the content of the present invention and implement it. It cannot be used to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
