For example, each first glue groove 3 can be provided with one, two, three or more second groove bodies 32. Thus, by providing the first glue groove 3, the mounting base a can prevent the glue from overflowing into the accommodation space 1, and at the same time can increase the surface area of glue adhesion, which helps to avoid product defects.

[0044] Figure 2 is a partial enlarged schematic view of the first glue groove provided by an embodiment of the present invention, as Figure 2 shown, in one embodiment, the first groove body 31 includes a first groove bottom 311 and first groove walls 312 located on both sides of the first groove bottom 311, and the first groove bottom 311 extends along the first direction X. Further, the second groove body 32 includes a second groove bottom 321 and second groove walls 322 located on both sides of the second groove bottom 321, and the second groove bottom 321 extends along the second direction Y. Further still, the first groove bottom 311 is connected to the second groove bottom 321, and a partial area of one of the first groove walls 312 is disconnected to be connected to the second groove wall 322. In this embodiment, the first groove bottom 311 and the first groove walls 312 form a U-shaped groove structure, and the second groove bottom 321 and the second groove walls 322 form a U-shaped groove structure. It should be noted that the first glue groove 3 in this embodiment is set as a U-shaped groove structure, which is convenient for processing and forming and helps to prevent glue overflow. Optionally, the first glue groove 3 can also be set as a V-shaped groove structure or other structures.

[0045] as Figure 2 shown, in one embodiment, the first groove bottom 311 and the first groove walls 312 are respectively set as plane structures, and the second groove bottom 321 and the second groove walls 322 are respectively set as plane structures.

Optionally, the first groove bottom 311 and / or the first groove walls 312 can also be set as curved surface structures, and the second groove bottom 321 and / or the second groove walls 322 can also be set as curved surface structures.

[0046] Figure 3 is a schematic structural view of another perspective of the mounting base provided by an embodiment of the present invention, as Figure 3As shown, in one embodiment, the outer wall 2 further includes a second outer wall 22. Further, a second glue groove 4 extending continuously along the first direction X is provided on the second outer wall 22. It should be noted that the continuously extending second glue groove 4 helps to guide the glue to flow in the groove and can accommodate more glue. At the same time, it also helps to estimate the required amount of glue to prevent overcoating. Thus, by providing the second glue groove 4, the mounting base a can prevent the glue from overflowing into the accommodation space 1, and at the same time, it can also increase the surface area of glue adhesion, which helps to avoid product defects.

[0047] Figure 4 is a partial enlarged schematic view of the second glue groove provided by an embodiment of the present invention. As Figure 4 shown, in one embodiment, the second glue groove 4 includes a third groove bottom 41 extending continuously along the first direction X and third groove walls 42 located on both sides of the third groove bottom 41. Further, the third groove bottom 41 and the third groove walls 42 form a U-shaped groove structure. It should be noted that the second glue groove 4 in this embodiment is set as a U-shaped groove structure, which is convenient for processing and forming and helps to prevent glue overflow. Optionally, the second glue groove 4 can also be set as a V-shaped groove structure or other structures.

[0048] As Figure 4 shown, in one embodiment, the third groove bottom 41 and the third groove walls 42 are respectively set as planar structures. It should be noted that the cross-section of the second glue groove 4 in this embodiment is set as a rectangle, which is convenient for processing and forming and helps to prevent glue overflow. Optionally, the third groove bottom 41 and / or the third groove walls 42 can also be set as curved surface structures.

[0049] Combined with Figure 1 and Figure 3 shown, in one embodiment, the first outer wall 21 and the second outer wall 22 are arranged opposite to each other. Thus, the positions of the first glue groove 3 and the second glue groove 4 can be selected to adapt to the outer shape structure of the mounting base a, so that they can cooperate with each other to prevent the glue from overflowing into the accommodation space 1, and further prevent product defects.

[0050] Combined with Figure 1 and Figure 3As shown, in one embodiment, the outer wall 2 further includes a third outer wall 23 and a fourth outer wall 24. Further, a third glue groove 5 is formed by the upper edge of the third outer wall 23 and / or the fourth outer wall 24 being recessed. That is to say, the third glue groove 5 is arranged as a stepped structure. It should be noted that the third glue groove 5 arranged at the edge can cooperate with other glue grooves to prevent glue overflow. The specific process is that the glue flows to the third glue groove 5 after passing through other glue grooves. Therefore, the third glue groove 5 can be selectively arranged at the position where the glue overflow problem is serious. Optionally, the third glue groove 5 can also be arranged on the first outer wall 21 and / or the second outer wall 22 to cooperate with the first glue groove 3 and / or the second glue groove 4 to prevent glue overflow.

[0051] Figure 5 is a partial enlarged schematic view of the third glue groove provided by an embodiment of the present invention, as Figure 5 As shown, in one embodiment, the third glue groove 5 includes a first fourth groove bottom 51 and a fourth groove wall 52. Further, the fourth groove bottom 51 and the fourth groove wall 52 form an L-shaped groove structure. It should be noted that the third glue groove 5 in this embodiment is arranged as an L-shaped groove structure, which is convenient for processing and forming and helps to prevent glue overflow. Optionally, the third glue groove 5 can also be arranged as a V-shaped groove structure or other structures.

[0052] As Figure 5 shown, in one embodiment, the fourth groove bottom 51 is arranged as a planar structure, and the fourth groove wall 52 is arranged as a curved surface structure. It should be noted that the specific structure of the third glue groove 5 can be matched with the outer shape structure of the mounting base a, while considering the processing efficiency and the glue overflow prevention effect. Optionally, the fourth groove bottom 51 can also be arranged as a curved surface structure, and the fourth groove wall 52 can also be arranged as a planar structure.

[0053] Combined with Figure 1 and Figure 3 shown, in one embodiment, the third outer wall 23 and the fourth outer wall 24 are arranged opposite to each other. It should be noted that the positions of the first glue groove 3, the second glue groove 4 and the third glue groove 5 can be selected according to the specific structure of the mounting base a and the actual glue overflow situation, so as to be reasonably distributed on the first outer wall 21, the second outer wall 22, the third outer wall 23 and the fourth outer wall 24.

[0054] Combined with Figure 1 and Figure 3 shown, in one embodiment, at least one notch 6 is formed by the side of the mounting base a facing upward being recessed, and the third glue groove 5 is arranged at the notch 6. It is easy to understand that the problem of glue overflow is likely to occur at the position of the notch 6, and arranging the third glue groove 5 at the notch 6 is to protect the weak position.

[0055] Combined with Figure 1 andFigure 3 As shown, in one embodiment, the lower edge of the outer wall 2 bulges outward to form a protruding portion 25. It should be noted that the protruding portion 25 can play a certain limiting role during the assembly of the mounting base a. In addition, the protruding portion 25 can also prevent the glue from overflowing downward.

[0056] Combined with Figure 1 and Figure 3 As shown, in one embodiment, the side of the protruding portion 25 facing upward is provided with a serrated structure. It is easy to understand that the serrated structure helps to guide the flow direction of the excess glue, while the protruding structure can prevent the glue from flowing downward continuously. Thus, the protruding portion 25 can improve the glue overflow prevention ability of the mounting base a on the basis of different glue grooves.

[0057] Combined with Figure 1 and Figure 3 As shown, in one embodiment, the mounting base a has a plurality of chamfers 7. It should be noted that the chamfers 7 can improve the assembly performance of the mounting base a, and at the same time can provide more space to accommodate the glue when the mounting base a is assembled with the housing, so as to prevent glue overflow and improve the bonding effect of the glue, which helps to improve the product yield.

[0058] Combined with Figure 1 and Figure 3 As shown, in one embodiment, the chamfer 7 includes a first part 71, a second part 72 and a third part 73. Further, the first part 71 is provided with a first groove 711, the second part 72 is provided with a second groove 721, and the third part 73 is provided with a third groove 731.

Further, the bottom size of the first groove 711 is greater than the bottom size of the third groove 731, and the bottom size of the third groove 731 is greater than the bottom size of the second groove 721. Optionally, the bottoms of the first groove 711, the second groove 721 and the third groove 731 can be set to a flat structure or a curved surface structure, the groove walls of the first groove 711, the second groove 721 and the third groove 731 can be set to a flat structure or a curved surface structure, and the groove walls of the first groove 711, the second groove 721 and the third groove 731 can be inclined at a certain angle relative to the groove bottom. It should be noted that by setting the structural dimensions of the first groove 711, the second groove 721 and the third groove 731, the glue overflow prevention effect of the chamfer 7 can be improved.

[0060] Combined with Figure 1 and Figure 3 As shown, in one embodiment, a fourth glue groove 8 is provided on the outer wall 2. Further, the fourth glue groove 8 includes a third groove body 81 arranged along the first direction X, a fourth groove body 82 bent relative to the third groove body 81, and at least one fifth groove body 83 arranged along the second direction Y. Among them, the fourth groove body 82 communicates with the third groove body 81, and the fifth groove body 83 communicates with the third groove body 81. It should be noted that by providing the bent fourth groove body 82, the fourth glue groove 8 can conveniently adapt to the outer shape structure of the outer wall 2. By providing the fifth groove body 83 with a different direction on the basis of the third groove body 81, the ability to prevent glue overflow can be improved. At the same time, the bending angle and the number of bends of the fourth groove body 82 can be set according to the outer shape structure of the outer wall 2 and the actual glue overflow situation. Optionally, the fourth groove body 82 can be provided on the first outer wall 21, the second outer wall 22, the third outer wall 23, and / or the fourth outer wall 24 as needed. It should be further noted that the sizes of the third groove body 81, the fourth groove body 82, and the fifth groove body 83 can be adjusted according to the outer shape structure of the outer wall 2 and the actual glue overflow situation. On the other hand, the number of the fifth groove bodies 83 can be set according to the outer shape structure of the outer wall 2 and the actual glue overflow situation. For example, each fourth glue groove 8 can be provided with one, two, three or more fifth groove bodies 83. Thus, by providing the fourth glue groove 8, the mounting base a can prevent glue from overflowing into the accommodation space 1, and at the same time, it can also increase the surface area of glue adhesion, which helps to avoid product defects.

[0061] Combined with Figure 1 and Figure 3 As shown, in one embodiment, the fourth glue groove 8 further includes a sixth groove body 84. Specifically, the sixth groove body 84 communicates with the third groove body 81, and the width of the sixth groove body 84 is greater than the width of the third groove body 81. Further, a contact portion 9 is formed by protruding on the outer wall 2, and the contact portion 9 extends into the sixth groove body 84. It should be noted that the contact portion 9 is used to contact the outer shell to ensure the firm assembly of the mounting base a. On this basis, by providing the sixth groove body 84 at the position of the contact portion 9, the fourth glue groove 8 can cooperate with the contact portion 9 to further prevent glue overflow.

[0062] Combined with Figure 1 and Figure 3 As shown, in one embodiment, the fourth glue groove 8 further includes a seventh groove body 85. Specifically, the seventh groove body 85 communicates with the third groove body 81, and the seventh groove body 85 is bent relative to the third groove body 81. It should be noted that the seventh groove body 85 is located at the end of the fourth glue groove 8 and bends downward, which helps to improve the glue overflow prevention ability of the fourth glue groove 8.

[0063] In one embodiment, the vertical cross-sections of the third groove 81, the fourth groove 82, the fifth groove 83, the sixth groove 84, and the seventh groove 85 are rectangular to form a U-shaped groove structure, which is convenient for processing and forming and helps prevent glue overflow. Optionally, each part of the fourth glue groove 8 can also be set as a V-shaped groove structure or other structures.

[0064] Combined with Figure 1 and Figure 3 As shown, in one embodiment, a leakage groove 26 is provided at the lower edge of the outer side wall 2. Specifically, the leakage groove 26 is located below the fifth groove 83 and communicates with the fifth groove 83. It is easy to understand that the fifth groove 83 cooperating with the leakage groove 26 can improve the anti-glue-overflow ability of the fourth glue groove 8.

[0065] The embodiment of the present invention also provides a voice coil motor. Figure 6 is a schematic structural diagram of the voice coil motor provided by the embodiment of the present invention. Figure 7 is an exploded schematic diagram of the voice coil motor provided by the embodiment of the present invention. Combined with Figure 6 and Figure 7 As shown, the voice coil motor H includes a mounting base a. It should be noted that the specific structure of the mounting base a is as described above and will not be elaborated here. Thus, the voice coil motor H can prevent glue from overflowing into the accommodation space 1 through the mounting base a provided with a glue groove, and at the same time, it can also increase the surface area of glue adhesion, which helps to avoid product defects.

[0066] Combined with Figure 6 and Figure 7 As shown, in one embodiment, the voice coil motor H further includes a housing b and a colloid c. Specifically, the housing b is sleeved on the outer side wall 2 of the mounting base a, and the lower edge of the housing b is provided with a serrated structure. Further, the colloid c is located between the housing b and the mounting base a. It is easy to understand that a part of the colloid c is located in the first glue groove 3, the second glue groove 4, the third glue groove 5, and the fourth glue groove 8. It should be noted that the lower edge of the housing b matches the convex portion 25, and the convex portion 25 protrudes outward from the housing b by a certain distance, so as to ensure that the colloid c will not be coated downward.

[0067] As Figure 7As shown, in one embodiment, the voice coil motor H further includes a carrier d, a magnet e, an upper elastic sheet f, and a lower elastic sheet g. Specifically, a coil is sleeved on the periphery of the carrier d, and a lens is installed at the center of the carrier d.
