[0041] Figure 1 is a schematic structural diagram of the mounting base provided by the embodiment of the present invention, as Figure 1As shown in the figure, the mounting base a has a plurality of outer sidewalls 2, and the middle area of the mounting base a is hollowed out to form a receiving space 1. It should be noted that the mounting base a is used in the voice coil motor of the camera device, and the lens of the camera device is arranged in the receiving space 1. Further, the outer sidewall 2 includes a first outer sidewall 21, and a plurality of first glue grooves 3 are provided on the first outer sidewall 21. The plurality of first glue grooves 3 are arranged at intervals along the first direction X. Further still, the first glue groove 3 includes a first groove body 31 and at least one second groove body 32. The first groove body 31 is arranged along the first direction X, and the second groove body 32 is arranged along the second direction Y. The second groove body 32 communicates with the first groove body 31. It should be noted that the first direction X and the second direction Y are two different directions on the first outer sidewall 21. Optionally, the direction in which the outer sidewall 2 extends in the horizontal direction is the first direction X, that is, the first direction X is the horizontal direction, and the second direction Y is the vertical direction.

[0042] It should be noted that the segmented first glue groove 3 can conveniently adapt to the outer shape structure of the first outer sidewall 21, and at the same time helps to selectively arrange the first glue groove 3 at the position where the glue overflow problem is serious. Further, by providing the second groove body 32 with a different direction on the basis of the first groove body 31, the first glue groove 3 helps to improve the ability to prevent glue overflow. It should be further noted that the sizes of the first groove body 31 and the second groove body 32 can be adjusted according to the outer shape structure of the first outer sidewall 21 and the actual glue overflow situation. Further still, the end of the first glue groove 3 is set to be arc-shaped to improve the ability to prevent glue overflow. On the other hand, the number of the second groove bodies 32 can be set according to the outer shape structure of the first outer sidewall 21 and the actual glue overflow situation. 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 receiving space 1, and at the same time can increase the surface area of glue adhesion, which helps to avoid product defects.

[0043] Figure 2 is a partial enlarged schematic view of the first glue groove provided by the embodiment of the present invention, as Figure 2As shown, in one embodiment, the first groove 31 includes a first groove bottom 311 and first groove walls 312 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 32 includes a second groove bottom 321 and second groove walls 322 on both sides of the second groove bottom 321, and the second groove bottom 321 extends along the second direction Y. Still further, 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.

[0044] As Figure 2 shown, in one embodiment, the first groove bottom 311 and the first groove walls 312 are respectively set as planar structures, and the second groove bottom 321 and the second groove walls 322 are respectively set as planar structures. It should be noted that the cross-sections of the first groove 31 and the second groove 32 in this embodiment are both rectangular, which is convenient for processing and forming and helps to prevent glue overflow. 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.

[0045] Figure 3 is a schematic structural diagram of another perspective of the mounting base provided by the embodiment of the present invention. As Figure 3 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 excessive coating. Thus, by providing the second glue groove 4, the mounting base a can prevent the glue from overflowing into the accommodating space 1, and at the same time, it can also increase the surface area of glue adhesion, which helps to avoid product defects.

[0046] Figure 4 is a partial enlarged schematic diagram of the second glue groove provided by the embodiment of the present invention. As Figure 4As shown, in one embodiment, the second glue tank 4 includes a third tank bottom 41 continuously extending along the first direction X and third tank walls 42 located on both sides of the third tank bottom 41. Further, the third tank bottom 41 and the third tank walls 42 form a U-shaped tank structure. It should be noted that the second glue tank 4 in this embodiment is set as a U-shaped tank structure, which is not only convenient for processing and forming, but also helps to prevent glue overflow. Optionally, the second glue tank 4 can also be set as a V-shaped tank structure or other structures.

[0047] As Figure 4 shown, in one embodiment, the third tank bottom 41 and the third tank walls 42 are respectively set as planar structures. It should be noted that the cross-section of the second glue tank 4 in this embodiment is set as a rectangle, which is not only convenient for processing and forming, but also helps to prevent glue overflow. Optionally, the third tank bottom 41 and / or the third tank walls 42 can also be set as curved surface structures.

[0048] Combined with Figure 1 and Figure 3 shown, in one embodiment, the first outer wall 21 and the second outer wall 22 are oppositely arranged. Thus, the position selection of the first glue tank 3 and the second glue tank 4 can be adapted 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, thereby preventing product defects.

[0049] Combined with Figure 1 and Figure 3 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 tank 5 is formed by the upper edges of the third outer wall 23 and / or the fourth outer wall 24 being recessed. That is to say, the third glue tank 5 is set as a stepped structure. It should be noted that the third glue tank 5 is arranged at the edge to cooperate with other glue tanks to prevent glue overflow. The specific process is that the glue flows to the third glue tank 5 after passing through other glue tanks. Therefore, the third glue tank 5 can be selectively arranged at the position where the glue overflow problem is serious. Optionally, the third glue tank 5 can also be arranged on the first outer wall 21 and / or the second outer wall 22 to cooperate with the first glue tank 3 and / or the second glue tank 4 to prevent glue overflow.

[0050] Figure 5 is a partial enlarged schematic diagram of the third glue tank provided by the embodiment of the present invention. As Figure 5 shown, in one embodiment, the third glue tank 5 includes a first and fourth tank bottom 51 and a fourth tank wall 52. Further, the fourth tank bottom 51 and the fourth tank wall 52 form an L-shaped tank structure. It should be noted that the third glue tank 5 in this embodiment is set as an L-shaped tank structure, which is not only convenient for processing and forming, but also helps to prevent glue overflow. Optionally, the third glue tank 5 can also be set as a V-shaped tank structure or other structures.

[0051] As Figure 5As shown, in one embodiment, the bottom of the fourth groove 51 is arranged as a planar structure, and the wall of the fourth groove 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 bottom of the fourth groove 51 can also be arranged as a curved surface structure, and the wall of the fourth groove 52 can also be arranged as a planar structure.

[0052] Combined with Figure 1 and Figure 3 As 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.

[0053] Combined with Figure 1 and Figure 3 As shown, in one embodiment, at least one notch 6 is formed by the depression on the upward-facing side of the mounting base a, 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.

[0054] Combined with Figure 1 and Figure 3 As shown, in one embodiment, the lower edge of the outer wall 2 bulges outward to form a convex portion 25. It should be noted that the convex portion 25 can play a certain limiting role during the assembly of the mounting base a. In addition, the convex portion 25 can also play a role in preventing the glue from overflowing downward.

[0055] Combined with Figure 1 and Figure 3 As shown, in one embodiment, the upward-facing side of the convex portion 25 is arranged as a serrated structure. It is easy to understand that the serrated structure helps to guide the flow direction of the excess glue, while the convex structure can prevent the glue from flowing downward continuously. Thus, the convex portion 25 can improve the glue overflow prevention ability of the mounting base a on the basis of different glue grooves.

[0056] 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 outer shell, so as to prevent glue overflow and improve the bonding effect of the glue, which helps to improve the product yield.

[0057] Combined with Figure 1 and Figure 3As shown, in one embodiment, the chamfer 7 includes a first portion 71, a second portion 72, and a third portion 73. Further, the first portion 71 is provided with a first groove 711, the second portion 72 is provided with a second groove 721, and the third portion 73 is provided with a third groove 731. It should be noted that the first groove 711, the second groove 721, and the third groove 731 can improve the anti-glue overflow effect of the chamfer 7.

[0058] Combined with Figure 1 and Figure 3 As shown, in one embodiment, the depth of the first groove 711 is greater than that of the third groove 731, and the depth of the third groove 731 is greater than that of the second groove 721. 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 planar 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 planar 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 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 anti-glue overflow effect of the chamfer 7 can be improved.

[0059] Combined with Figure 1 and Figure 3As shown, in one embodiment, a fourth glue groove 8 is provided on the outer sidewall 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 the fourth glue groove 8 can conveniently adapt to the outer shape structure of the outer sidewall 2 by providing the bent fourth groove body 82, and the ability to prevent glue overflow can be improved by providing the fifth groove body 83 with different directions on the basis of the third groove body 81. 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 sidewall 2 and the actual glue overflow situation. Optionally, the fourth groove body 82 can be provided on the first outer sidewall 21, the second outer sidewall 22, the third outer sidewall 23, and / or the fourth outer sidewall 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 sidewall 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 sidewall 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.

[0060] 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 butting portion 9 is formed in a protruding manner on the outer sidewall 2, and the butting portion 9 extends into the sixth groove body 84. It should be noted that the butting portion 9 is used to butt against the outer shell to ensure the firm assembly of the mounting base a. On this basis, the fourth glue groove 8 is provided with the sixth groove body 84 at the position of the butting portion 9, which can cooperate with the butting portion 9 to further prevent glue overflow.

[0061] 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.

[0062] 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.

[0063] 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 sidewall 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.

[0064] 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 glue grooves, and at the same time, it can also increase the surface area of glue adhesion, which helps to avoid product defects.

[0065] 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 sidewall 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 protrusion 25, and the protrusion 25 protrudes outward from the housing b by a certain distance, so as to ensure that the colloid c will not be coated downward.

[0066] As Figure 7As shown, in one embodiment, a voice coil motor H further comprises a carrier d, a magnet e, an upper spring f, and a lower spring g. Specifically, a coil is sheathed around the carrier d, with the center of the carrier d being used to mount a lens. Four magnets e are located at the four corners of the carrier d. The upper spring f is positioned above the carrier d and magnet e and connected to the housing b. The lower spring g is positioned below the carrier d and magnet e and rests on the mounting base a. It is easy to understand that when the coil in the voice coil motor H is energized, the electromagnetic force generated drives the coil 11 axially, thereby moving the carrier d, which holds the lens, and thus enabling the lens to focus. The upper spring f and lower spring g enable the carrier d to reset when the coil is de-energized.

[0067] An embodiment of the present invention further provides a camera device, Figure 8 : is a structural diagram of a camera device provided by an embodiment of the present invention, such as Figure 8 As shown, the camera device includes a voice coil motor H and a lens I. The specific structure of the voice coil motor H is described above and will not be repeated here. Furthermore, the lens I is mounted on the voice coil motor H, enabling focusing under the action of the voice coil motor H. The mounting base a, with its glue groove, prevents glue from overflowing into the receiving space 1 and increases the surface area for glue adhesion, thereby improving the quality of the camera device.

[0068] An embodiment of the present invention provides a voice coil motor and a camera device. The voice coil motor includes a mounting base, a housing, and a colloid. The mounting base has a hollowed-out central area to form a receiving space. The mounting base has multiple outer walls, the lower edges of which protrude outward to form a raised portion. The housing is fitted over the outer walls of the mounting base, with the lower edge of the housing mating with the raised portion. The colloid is located between the housing and the mounting base. This prevents glue from overflowing into the receiving space through the mounting base and increases the surface area available for glue, helping to prevent product defects.

[0069] The foregoing is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application are intended to be within the scope of protection of the present application.
