It should be noted that, the receiving groove 20 has an opening, and at this time, the receiving groove 20 can be disposed through the opening, and the bottom wall 20a of the receiving groove 20 can be understood as a wall surface of a side of the receiving groove 20 away from the opening; the peripheral wall 20b of the housing groove 20 can be understood as a wall surface provided around the bottom wall 20a of the housing groove 20.

According to the gasket 1 of the lens driving device 100 of the embodiment of the utility model, by arranging the extension part 12 and enabling the extension part 12 to be suitable for being clamped between the peripheral wall 20b of the accommodating groove 20 and the magnet 3, the matching strength between the magnet 3 and the shell 2 can be improved, the magnet 3 is ensured to be reliably installed, the installation precision of the magnet 3 is conveniently ensured, and the use reliability of the lens driving device 100 is improved.

Thus, the at least one of the body portion 11 and the extension portion 12 can enhance the magnetic field generated by the magnet 3, so that the magnet 3 can better cooperate with the coil on the carrier, and the focusing effect of the lens driving device 100 can be ensured.

It is understood that when the main body 11 and the extension 12 are both made of magnetic conductive material, the material of the main body 11 and the material of the extension 12 may be the same or different.

In some embodiments, as shown in fig. 1 and 2, the extending portion 12 is of an equal-thickness sheet structure, and the thickness of any position on the extending portion 12 is equal to the thickness of the rest positions, so that the extending portion 12 has a simple structure and is convenient to process, and meanwhile, the extending portion 12 is convenient to provide flat surfaces for the housing 2 and the magnet 3, which is beneficial to further ensure reliable installation of the magnet 2.

In some alternative embodiments, as shown in fig. 1 and fig. 2, the thickness of the extension portion 12 is smaller than or equal to the thickness of the housing 2, so that the extension portion 12 occupies a suitable space of the accommodating groove 20, the problem that the extension portion 12 occupies too much space to facilitate the layout of other components of the lens driving apparatus 100 can be avoided, and the problem that the magnet 3 cannot be reliably mounted due to too little space occupied by the extension portion 12 can be avoided.

In some embodiments, as shown in fig. 1, the length of the extension portion 12 is greater than or equal to the length of the magnet 3, so that the extension portion 12 is disposed between the entire magnet 3 and the peripheral wall 20b of the accommodating groove 20, which is convenient for ensuring the connection strength between the entire magnet 3 and the housing 2.

It can be understood that the length of the extension portion 12 and the length of the magnet 3 are both smaller than the length of the corresponding edge of the housing 1 to ensure that the extension portion 12 and the magnet 3 are both accommodated in the accommodating groove 20.

In some embodiments, as shown in fig. 1, two opposite sides of the main body 11 are respectively provided with the extending portions 12, each extending portion 12 is adapted to correspond to one magnet 3, and two opposite sides of the housing 2 are respectively provided with the magnets 3, so that the magnets 3 can apply a relatively balanced acting force to the coil, which is convenient for ensuring the motion consistency of the whole carrier.

In some embodiments, as shown in fig. 2, the main body 11 and the extension 12 are a single piece, which can save the assembly process between the main body 11 and the extension 12 and ensure that the main body 11 and the extension 12 are connected reliably.

It will be understood that the body portion 11 and the extension portion 12 may be formed by one-time machining, or the extension portion 12 may be machined after the body portion 11 is formed by machining, in which case the body portion 11 and the extension portion 12 may be formed after two machining processes. Regardless of the specific processing sequence of the integrated molding of the body portion 11 and the extension portion 12, it is sufficient that the body portion 11 and the extension portion 12 are integrated after the gasket 1 is integrally processed.

In addition, when the main body 11 and the extension 12 are a single piece, the material of the main body 11 and the material of the extension 12 may be the same or different. For example, the body portion 11 and the extension portion 12 are a single piece, and the body portion 11 and the extension portion 12 may be both magnetic conductive material pieces, in which case the whole gasket 1 may be a magnetic conductive material piece.

Of course, the present application is not so limited; in other embodiments, there is no connection between the body portion 11 and the extension portion 12, and the body portion 11 and the extension portion 12 may be formed as a split structure, so as to facilitate flexible arrangement of the body portion 11 and the extension portion 12, so that the gasket 1 may better adapt to actual differentiation requirements.

It is understood that when there is no connection between the body portion 11 and the extension portion 12, the material of the body portion 11 and the material of the extension portion 12 may be the same or different.
