Problems solved by technology

[0003] When the carrier is driven to move through the magnet and coil structure, it is easy to cause the carrier to vibrate relative to the base. In order to prevent the carrier from shaking, some lens driving devices are equipped with damping glue to play a damping role, thereby preventing the carrier from shaking. When damping glue, the uncured damping glue flows so that it is not easy to fix the position of the damping glue, and the damping glue is easy to be thrown off, and there is also the problem of inaccurate location of the damping glue point

Embodiment 1

[0034] Embodiment 1: as Figure 1 to Figure 6 As shown, a damping glue installation structure proposed by the present invention includes a base 1 and a carrier 2. The edge of the base 1 is integrally formed with a bracket 3. There are four brackets 3 and they are respectively located at the corners of the base 1. The brackets 3 is a plane toward the center of the carrier 2 . There is a gap between the side wall of the carrier 2 and the bracket 3, and the bracket 3 is provided with a gap 4 for storing glue toward the side wall of the carrier 2, and the gap 4 extends to the side of the bracket 3 away from the base 1. At one end, damping glue is provided at the position of the notch 4 . When dispensing damping glue, the damping glue is set at the position of the gap 4, and the damping glue is in contact with the carrier 2 on the opposite side, so that the damping glue can play a corresponding damping effect between the carrier 2 and the bracket 3; because the bracket 3 A notch ...

Embodiment 2

[0038] Embodiment 2, compared with embodiment 1, differs in that: as Figure 7 As shown, the notch 4 is in the shape of a groove, and the sides of the notch 4 do not extend to the edge of the bracket 3 . In this structure, the damping glue can be restricted from being thrown out by the sides on both sides of the notch 4 , and the damping glue can be ensured to be located at the notch 4 .

Embodiment 3

[0039] Embodiment 3: a kind of lens driving device, such as Figure 8 to Figure 10 As shown, it has the damping glue installation structure described in Embodiment 1, and a glue dispensing groove 7 for fixing the coil 6 is opened on the side wall of the carrier 2, that is, the glue dispensing groove 7 is located between the carrier 2 and the coil 6, and the glue dispensing groove 7 extends to the end of the carrier 2 away from the base 1 . When the coil 6 is installed on the carrier 2, glue is dispensed at the position of the dispensing tank 7, and the glue remains in the dispensing tank 7 and contacts the coil 6, so as to realize the dispensing and fixing of the coil 6, and prevent the glue from flowing out, and play a role of storage Glue effect.

[0040] An inclined surface 8 is provided between the glue dispensing groove 7 and an edge of the carrier 2 facing away from the base 1 to facilitate the flow of glue into the glue dispensing groove 7 . The glue dispensing inlet ...

Abstract

The invention discloses a damping glue installation structure, a lens driving device, a photographic device, and an electronic product. The key points of the technical solution are: a damping glue installation structure, including a base and a carrier, the edge of the base is integrally formed with a bracket, and the side of the carrier is There is a gap between the wall and the bracket, and the bracket is provided with a gap for storing glue facing the side wall of the carrier, and damping glue is provided at the position of the gap. The invention effectively fixes the position of the damping glue, prevents the damping glue from falling off, and effectively increases the storage capacity of the damping glue.

Description

technical field [0001] The invention relates to the field of imaging equipment, in particular to a damping glue installation structure, a lens driving device, a photographing device and electronic products. Background technique [0002] The existing lens driving device mainly includes a housing, a base, a carrier, an upper spring, a lower spring, a magnet, a coil, etc., and is used to drive the installed lens to move and realize the focusing function. [0003] When the carrier is driven to move through the magnet and coil structure, it is easy to cause the carrier to vibrate relative to the base. In order to prevent the carrier from shaking, some lens driving devices are equipped with damping glue to play a damping role, thereby preventing the carrier from shaking. When damping glue, the uncured damping glue flows so that it is not easy to fix the position of the damping glue, and the damping glue is easy to be thrown off, and there is also the problem of inaccurate damping ...
