Further, the second outer side wall 22 is provided with a second adhesive groove 4 that extends continuously along the first direction X. It should be noted that the continuously extending second adhesive groove 4 helps guide the flow of adhesive within the groove and can hold more adhesive, while also helping to estimate the required amount of adhesive to prevent over-application. Thus, by providing the second adhesive groove 4, the base a can prevent adhesive overflow into the receiving space 1, and can also increase the surface area for adhesive adhesion, helping to avoid product defects.

[0047] Figure 4 This is a partially enlarged schematic diagram of the second adhesive groove provided in an embodiment of the present invention, as shown below. Figure 4As shown, in one embodiment, the second glue tank 4 includes a third tank bottom 41 extending continuously along a 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.

Optionally, the second glue tank 4 can also be configured as a V-shaped tank structure or other structures.

[0048] like Figure 4 As shown, in one embodiment, the third tank bottom 41 and the third tank wall 42 are respectively configured as planar structures. It should be noted that the cross-section of the second glue tank 4 in this embodiment is rectangular, which facilitates processing and helps prevent glue overflow. Optionally, the third tank bottom 41 and / or the third tank wall 42 can also be configured as curved structures.

[0049] Combination Figure 1 and Figure 3 As shown, in one embodiment, the first outer side wall 21 and the second outer side wall 22 are arranged opposite to each other. Therefore, the positions of the first glue groove 3 and the second glue groove 4 can be adapted to the shape and structure of the base a, so that they can cooperate to prevent glue from overflowing into the receiving space 1, thereby preventing product defects.

[0050] Combination Figure 1 and Figure 3 As shown, in one embodiment, the outer side wall 2 further includes a third outer side wall 23 and a fourth outer side wall 24. Further, a third adhesive groove 5 is formed by a recess at the upper edge of the third outer side wall 23 and / or the fourth outer side wall 24. That is, the third adhesive groove 5 is configured as a stepped structure. It should be noted that the third adhesive groove 5 is located at the edge to cooperate with other adhesive grooves to prevent adhesive overflow. Specifically, the adhesive flows to the third adhesive groove 5 after passing through other adhesive grooves. Therefore, the third adhesive groove 5 can be selectively located at locations where adhesive overflow is severe. Optionally, the third adhesive groove 5 can also be located on the first outer side wall 21 and / or the second outer side wall 22 to cooperate with the first adhesive groove 3 and / or the second adhesive groove 4 to prevent adhesive overflow.

[0053] Combination Figure 1 and Figure 3 As shown, in one embodiment, the third outer side wall 23 and the fourth outer side 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 base a and the actual glue overflow situation, so as to be reasonably distributed on the first outer side wall 21, the second outer side wall 22, the third outer side wall 23, and the fourth outer side wall 24.

[0054] Combination Figure 1 and Figure 3 As shown, in one embodiment, the base a has at least one notch 6 recessed on its upward-facing side, and a third adhesive groove 5 is provided at the notch 6. It is easy to understand that adhesive overflow is prone to occur at the location of the notch 6, and the third adhesive groove 5 is provided at the notch 6 to protect the vulnerable area.

[0055] Combination Figure 1 and Figure 3 As shown, in one embodiment, the lower edge of the outer wall 2 protrudes outward to form a protrusion structure 25. It should be noted that the protrusion structure 25 can provide a certain degree of restraint during the assembly of the base a. Furthermore, the protrusion structure 25 can also prevent adhesive from overflowing downwards.

[0056] Combination Figure 1 and Figure 3 As shown, in one embodiment, the upward-facing side of the raised structure 25 is configured with a serrated structure. It is readily understood that the serrated structure helps guide the flow of excess adhesive, while the raised structure prevents the adhesive from flowing further downwards. Thus, the raised structure 25 can improve the adhesive spillage prevention capability of the base a based on different adhesive channels.

[0057] Combination Figure 1 and Figure 3 As shown, in one embodiment, the base a has multiple chamfers 7. It should be noted that the chamfers 7 can improve the assembly performance of the base a, and at the same time, provide more space to accommodate glue when assembling the base a with the housing, thereby preventing glue overflow and improving the adhesive effect, which helps to improve product yield.

[0058] Combination 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 has a first groove 711, the second portion 72 has a second groove 721, and the third portion 73 has 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-overflow adhesive effect of the chamfer 7.

[0059] Combination 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.

The 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-overflow adhesive effect of the chamfer 7 can be improved.

[0060] Combination Figure 1 and Figure 3As shown, in one embodiment, a fourth adhesive groove 8 is provided on the outer side wall 2. Further, the fourth adhesive groove 8 includes a third groove 81 disposed along a first direction X, a fourth groove 82 bent relative to the third groove 81, and at least one fifth groove 83 disposed along a second direction Y. The fourth groove 82 connects to the third groove 81, and the fifth groove 83 connects to the third groove 81. It should be noted that the fourth adhesive groove 8, by providing the bent fourth groove 82, can easily adapt to the shape and structure of the outer side wall 2, and by providing a fifth groove 83 with a different direction based on the third groove 81, the ability to prevent adhesive overflow can be improved. Simultaneously, the bending angle and the number of bends of the fourth groove 82 can be set according to the shape and structure of the outer side wall 2 and the actual adhesive overflow situation. Optionally, the fourth groove 82 can be disposed on the first outer side wall 21, the second outer side wall 22, the third outer side wall 23, and / or the fourth outer side wall 24 as needed. It should be further explained that the dimensions of the third groove 81, the fourth groove 82, and the fifth groove 83 can be adjusted according to the external shape of the outer wall 2 and the actual glue overflow situation. On the other hand, the number of fifth grooves 83 can be set according to the external shape of the outer wall 2 and the actual glue overflow situation; for example, each fourth glue groove 8 can have one, two, three, or more fifth grooves 83. Therefore, by providing the fourth glue grooves 8, the base a can prevent glue from overflowing into the receiving space 1, and at the same time increase the surface area for glue adhesion, helping to avoid product defects.

[0061] Combination Figure 1 and Figure 3 As shown, in one embodiment, the fourth glue tank 8 further includes a sixth tank body 84. Specifically, the sixth tank body 84 connects to the third tank body 81, and the width of the sixth tank body 84 is greater than the width of the third tank body 81. Further, an abutment portion 9 is formed on the outer side wall 2, and the abutment portion 9 extends into the sixth tank body 84. It should be noted that the abutment portion 9 is used to abut against the housing to ensure that the base a is securely assembled. Based on this, the sixth tank body 84 provided at the position of the abutment portion 9 in the fourth glue tank 8 can further prevent glue overflow in conjunction with the abutment portion 9.

[0062] Combination Figure 1 and Figure 3 As shown, in one embodiment, the fourth glue tank 8 further includes a seventh tank body 85. Specifically, the seventh tank body 85 is connected to the third tank body 81, and the seventh tank body 85 is curved relative to the third tank body 81. It should be noted that the seventh tank body 85 is located at the end of the fourth glue tank 8 and is curved downward, which helps to improve the glue spillage prevention capability of the fourth glue tank 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 facilitates processing and helps prevent glue overflow. Optionally, each part of the fourth glue groove 8 can also be configured as a V-shaped groove structure or other structures.

[0064] Combination Figure 1 and Figure 3 As shown, in one embodiment, a groove 26 is provided at the lower edge of the outer wall 2. Specifically, the groove 26 is located below and communicates with the fifth groove 83. It is readily understood that the fifth groove 83, in conjunction with the groove 26, can improve the anti-overflow adhesive capability of the fourth adhesive groove 8.

[0065] This utility model embodiment also provides a voice coil motor. Figure 6 This is a structural schematic diagram of the voice coil motor provided in an embodiment of the present invention.

[0066] Combination 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 fitted onto the outer wall 2 of the base a, and the lower edge of the housing b is configured with a serrated structure. Further, the colloid c is located between the housing b and the base a. It is readily understood that a portion of the colloid c is located within the first colloid groove 3, the second colloid groove 4, the third colloid groove 5, and the fourth colloid groove 8. It should be noted that the lower edge of the housing b matches the protruding structure 25, and the protruding structure 25 protrudes outward relative to the housing b by a distance, thereby ensuring that the colloid c is not applied downwards.

[0067] like Figure 7As shown, in one embodiment, the voice coil motor H further includes a carrier d, magnets e, an upper spring f, and a lower spring g. Specifically, a coil is sleeved around the periphery of the carrier d, a lens is mounted at the center of the carrier d, four magnets e are located at the four corners of the carrier d, the upper spring f is located above the carrier d and magnets e and connected to the housing b, and the lower spring g is located below the carrier d and magnets e and is situated on the base a. It is easy to understand that when the coil in the voice coil motor H is energized, the generated electromagnetic force drives the coil 11 to move axially, thereby moving the carrier d with the lens, thus enabling the lens to focus. The upper spring f and the lower spring g allow the carrier d to reset after the coil is de-energized.
