Further, the second outer side wall 22 is provided with a second adhesive-receiving groove 4 that extends continuously along the first direction X. It should be noted that the continuously extending second adhesive-receiving 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-receiving groove 4, the motor base a can prevent adhesive overflow into the reserved space 1, and can also increase the surface area for adhesive adhesion, helping to avoid product defects.

[0043] Figure 4 This is a partially enlarged schematic diagram of the second adhesive container provided in an embodiment of the present invention, as shown below. Figure 4As shown, in one embodiment, the second adhesive container 4 includes a third bottom 41 extending continuously along a first direction X and third walls 42 located on both sides of the third bottom 41. Further, the third bottom 41 and the third walls 42 form a U-shaped groove structure. It should be noted that the second adhesive container 4 in this embodiment is configured as a U-shaped groove structure, which facilitates processing and helps prevent adhesive overflow. Optionally, the second adhesive container 4 can also be configured as a V-shaped groove structure or other structures.

[0044] 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 adhesive receiving tank 4 in this embodiment is rectangular, which facilitates processing and helps prevent adhesive overflow. Optionally, the third tank bottom 41 and / or the third tank wall 42 can also be configured as curved structures.

[0045] 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 adhesive reservoir 3 and the second adhesive reservoir 4 can be adapted to the external structure of the motor base a, thereby cooperating to prevent adhesive overflow into the reserved space 1 and thus preventing product defects.

[0046] 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 with 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.

Optionally, the fourth groove bottom 51 can also be configured as a curved structure, and the fourth groove wall 52 can also be configured as a planar structure.

[0049] 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 adhesive reservoir 3, the second adhesive reservoir 4, and the third adhesive reservoir 5 can be selected according to the specific structure of the motor base a and the actual adhesive 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.

[0050] Combination Figure 1 and Figure 3 As shown, in one embodiment, the motor base a has at least one notch 6 recessed on its upward-facing side, and a third adhesive reservoir 5 is disposed 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 reservoir 5 is provided at the notch 6 to protect the vulnerable area.

[0051] Combination Figure 1 and Figure 3 As shown, in one embodiment, the lower edge of the outer side wall 2 protrudes outward to form a protrusion 25. It should be noted that the protrusion 25 can provide a certain degree of restraint during the assembly of the motor base a. Furthermore, the protrusion 25 can also prevent adhesive from overflowing downwards.

[0052] Combination Figure 1 and Figure 3 As shown, in one embodiment, the upward-facing side of the protrusion 25 is configured with a serrated structure. It is readily understood that the serrated structure helps guide the flow direction of excess adhesive, while the protruding structure prevents the adhesive from continuing to flow downwards. Thus, the protrusion 25 can improve the anti-overflow adhesive capability of the motor base a based on different adhesive reservoirs.

[0053] Combination Figure 1 and Figure 3 As shown, in one embodiment, the motor base a has multiple chamfers 7. It should be noted that the chamfers 7 improve the assembly performance of the motor base a, and also provide more space to accommodate adhesive during assembly of the motor base a and the housing, thereby preventing adhesive overflow and improving the bonding effect of the adhesive, which helps to improve product yield.

[0054] Combination Figure 1 and Figure 3 As 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.

[0055] 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.

[0056] Combination Figure 1 and Figure 3As shown, in one embodiment, a fourth adhesive reservoir 8 is provided on the outer side wall 2. Further, the fourth adhesive reservoir 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 communicates with the third groove 81, and the fifth groove 83 communicates with the third groove 81. It should be noted that the fourth adhesive reservoir 8, by providing the bent fourth groove 82, can easily adapt to the external shape 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 number of bends of the fourth groove 82 can be set according to the external shape 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-receiving groove 8 can have one, two, three, or more fifth grooves 83. Therefore, by providing the fourth glue-receiving grooves 8, the motor base a can prevent glue from overflowing into the reserved space 1, and at the same time increase the surface area for glue adhesion, helping to avoid product defects.

[0057] Combination Figure 1 and Figure 3 As shown, in one embodiment, the fourth adhesive reservoir 8 further includes a sixth groove 84. Specifically, the sixth groove 84 connects to the third groove 81, and the width of the sixth groove 84 is greater than the width of the third groove 81. Further, a protruding abutment 9 is formed on the outer wall 2, and the abutment 9 extends into the sixth groove 84. It should be noted that the abutment 9 is used to abut against the housing to ensure that the motor base a is securely assembled. Based on this, the sixth groove 84 provided at the position of the abutment 9 in the fourth adhesive reservoir 8 can further prevent adhesive overflow in conjunction with the abutment 9.

[0058] Combination Figure 1 and Figure 3 As shown, in one embodiment, the fourth adhesive reservoir 8 further includes a seventh groove 85. Specifically, the seventh groove 85 communicates with the third groove 81, and the seventh groove 85 is curved relative to the third groove 81. It should be noted that the seventh groove 85 is located at the end of the fourth adhesive reservoir 8 and is curved downward, which helps to improve the adhesive spillage prevention capability of the fourth adhesive reservoir 8.

[0059] 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-containing groove 8 can also be configured as a V-shaped groove structure or other structures.

[0060] Combination Figure 1 and Figure 3 As shown, in one embodiment, a drainage groove 26 is provided at the lower edge of the outer wall 2. Specifically, the drainage 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 drainage groove 26, can improve the anti-overflow adhesive capability of the fourth adhesive reservoir 8.

[0061] This utility model embodiment also provides a voice coil motor. Figure 6 This is a schematic diagram of the structure of the voice coil motor provided in this embodiment of the utility model. Figure 7 This is an exploded view of the voice coil motor provided in this embodiment of the utility model, combined with... Figure 6 and Figure 7 As shown, the voice coil motor H includes a motor base a. It should be noted that the specific structure of the motor base a is as described above and will not be repeated here. Therefore, the motor base a, which has an adhesive reservoir, prevents adhesive from overflowing into the reserved space 1, and also increases the surface area for adhesive adhesion, helping to avoid product defects.

[0062] 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 motor 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 motor base a. It is readily understood that a portion of the colloid c is located within the first colloid reservoir 3, the second colloid reservoir 4, the third colloid reservoir 5, and the fourth colloid reservoir 8. It should be noted that the lower edge of the housing b matches the protrusion 25, and the protrusion 25 protrudes outwards relative to the housing b by a certain distance, thereby ensuring that the colloid c is not applied downwards.

[0063] like Figure 7As shown, in one embodiment, the voice coil motor H further includes a carrier d, a magnet 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 the magnets e and connected to the housing b, and the lower spring g is located below the carrier d and the magnets e and is situated on the motor 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 return to its original position after the coil is de-energized.

[0064] This utility model embodiment also provides a camera device. Figure 8 This is a schematic diagram of the camera device provided in an embodiment of the present invention, as shown below.
