Problems solved by technology

[0003] Traditional micro drive motors generally include an upper cover, an upper gasket, an upper spring piece, a lens carrier, a magnet assembly, a coil assembly, a lower gasket, a lower spring assembly, and a base; when traditional products install the upper cover on the base, It is necessary to apply glue on the outer wall of the positioning boss of the base. After the glue penetrates the gap between the positioning boss and the inner wall of the shell, if it is redundant, it will also overflow from the adjacent surface of the upper cover and the base, that is, the joint line. And accumulate to form glue clots protruding from the outer wall of the shell, resulting in poor appearance

Embodiment approach

[0018] figure 1 and figure 2 A first embodiment of the invention is shown in which, figure 1 It is a schematic diagram of a three-dimensional structure of the first structure of the present invention; figure 2 Yes figure 1 An exploded view of the housing assembly shown.

[0019] This embodiment is a housing assembly for a micro drive motor, see figure 1 and figure 2 As shown, it includes an upper cover 1 and a base 2; the upper cover 1 includes a top wall 11 and a side wall 12 adjacent to the peripheral edge of the top wall 11, and a light-transmitting hole 13 is provided at the center of the top wall 11; The bottom end of the side wall 12 of the cover 1 or the outer wall of the base 2 are provided with a plurality of accommodating grooves 3 for accommodating glue, and each accommodating groove 3 is located on the adjacent surface of the two.

[0020] In this embodiment, the basic shapes of the upper cover 1 and the base 2 are square, and the four corners of the base ...

Embodiment 2

[0023] This embodiment is basically the same as the embodiment 1, except that each accommodating groove 3 is located on the side wall 12 of the upper cover 1 outside each positioning post 21 .

[0024] In the above embodiment 1 and embodiment 2, the bottom end of the side wall 12 of the upper cover 1 or the outer wall of the base 2 are provided with a plurality of accommodating grooves 3 for accommodating glue, and each accommodating groove 3 is located between the two. adjacent face. With this storage tank, although the excess glue overflows, it will accumulate in the storage tank due to the limited margin, and will not protrude and accumulate on the outer wall of the casing, so it effectively prevents defects caused by excessive glue. .

Abstract

The invention discloses a shell assembly for a micro-driving motor. The shell assembly comprises an upper cover and a base, wherein the upper cover comprises a top wall and a side wall adjacent to the periphery of the top wall; the center of the top wall is provided with a light hole; the bottom of the side wall of the upper cover or the outer wall of the base is provided with a plurality of accommodating grooves for accommodating glue water; and each accommodating groove is positioned on adjacent surfaces of the upper cover and the base. By the accommodating grooves, excessive glue water can be accumulated in the accommodating grooves, and cannot stand out the outer wall of the shell, so adverse effects caused by excessive glue water are effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of micro-motor structure design, and in particular relates to a shell assembly for a micro-drive motor. Background technique [0002] Micro camera devices have been widely used in mobile phones and notebook computers, and the micro drive motors (also called lens drive motors) therein are getting smaller and smaller. [0003] Traditional micro drive motors generally include an upper cover, an upper gasket, an upper spring piece, a lens carrier, a magnet assembly, a coil assembly, a lower gasket, a lower spring assembly, and a base; when traditional products install the upper cover on the base, It is necessary to apply glue on the outer wall of the positioning boss of the base. After the glue penetrates the gap between the positioning boss and the inner wall of the shell, if it is redundant, it will also overflow from the adjacent surface of the upper cover and the base, that is, the joint line. And accumulat...
