Detailed Description

In order to make the technical means, the original characteristics, the achieved purposes and the effects of the invention easy to understand, the invention is further described with reference to the figures and the specific embodiments.

Example 1: as shown in fig. 1 to 6, the damping adhesive mounting structure provided by the invention comprises a base 1 and a carrier 2, wherein four brackets 3 are integrally formed at the edge of the base 1, the four brackets 3 are respectively located at the corners of the base 1, and the bracket 3 is a plane facing the center of the carrier 2. Leave the clearance between 2 lateral walls of carrier and the support 3, support 3 orientation 2 lateral wall one side of carrier is offered and is used for storing up the breach 4 of receiving glue, and breach 4 extends to support 3 deviates from the one end of

base

1, 4 positions in breach set up the damping and glue. When the damping glue is arranged in a point mode, the damping glue is arranged in the position of the notch 4 and is in contact with the carrier 2 on the opposite side, and therefore the damping glue achieves a corresponding damping effect between the carrier 2 and the support 3; the support 3 is provided with the notch 4, so that the storage amount of the damping glue is increased, in addition, the damping glue is arranged at the position of the notch 4, and the damping glue is limited by the lower side wall of the notch 4 to sink towards the base 1, so that the effect of positioning the damping glue is achieved; because the support 3 is located the corner position of base 1, damping glue is located the corner of carrier 2 promptly, when the damping glue was thrown away, the damping glue was difficult to contact carrier 2 lateral wall or 1 side relevant position of base to furthest reduces the influence to carrier 2 motion after the damping glue was thrown away.

In this embodiment, two sides of the notch 4 extend to the whole plane of the support 3 facing the center direction of the carrier 2, that is, a step structure is formed between the notch 4 and the support 3, and the storage amount of the damping glue is increased to the maximum extent by the step structure. In addition, the edge of one surface of the bracket 3 facing the center of the carrier 2 is provided with a chamfer 5. Make things convenient for the damping to glue and fill to 4 positions of breach through chamfer 5, realize the convenience that the point was established the damping and is glued.

In this embodiment, the carrier 2 is fixed with the coil 6, and the coil 6 is disposed around the carrier 2, that is, a groove for the coil 6 to surround is formed on the side wall of the carrier 2. Coil 6 is close to and is located same high position with the lateral wall that breach 4 is close to base 1 near base 1 one end, just coil 6 keeps away from base 1 one end and is less than support 3 and deviates from base 1 one end, and coil 6 is used for the height that breach 4 lateral wall position was flushed towards base 1 one end promptly, and the 6 other ends of coil are less than support 3 in addition. When the damping glue is arranged in a point mode, the damping glue is located between the notch 4 and the coil 6, and the damping effect on movement is still achieved; in addition, the other end of the coil 6 is lower than the height of the support 3, so that the influence on the carrier 2 and the spring is avoided after one end of the coil 6, which is far away from the base 1, is contacted with damping glue.

The part of the carrier 2, which is positioned on the coil 6 and faces the base 1, protrudes out of the outer side wall of the coil 6, and the gap between the part of the carrier 2, which is positioned on the coil 6 and faces the base 1, and the bracket 3 is smaller than the gap between the coil 6 and the notch 4. That is, the gap formed between the part of the carrier 2 close to the base 1 and the bracket 3 is far smaller than the gap formed between the coil 6 and the notch 4, so as to ensure that the damping glue cannot flow toward the carrier 2 along the gap formed between the part of the carrier 2 close to the base 1 and the bracket 3.

Example 2 differs from example 1 in that: as shown in fig. 7, the notch 4 is groove-shaped, and the two side edges of the notch 4 do not extend to the edge position of the bracket 3. In the structure, the damping glue can be limited from being thrown out through the two side edges of the notch 4, and the damping glue is ensured to be positioned at the notch 4.

Example 3: a lens driving device, as shown in fig. 8 to 10, has the damping adhesive mounting structure described in embodiment 1, and a dispensing slot 7 for fixing a coil 6 is opened on a side wall of a carrier 2, that is, the dispensing slot 7 is located between the carrier 2 and the coil 6, and the dispensing slot 7 extends to an end of the carrier 2 away from a base 1. When installing coil 6 in carrier 2, point 7 positions of gluing the groove and glue, glue persists in point 7 and contacts with coil 6 of gluing the groove to it is fixed to realize the point of coil 6, and avoids glue outflow, plays and stores up the glue effect.

An inclined surface 8 which is convenient for glue to flow into the glue dispensing groove 7 is arranged between the glue dispensing groove 7 and the edge of one end of the carrier 2 which deviates from the base 1. Glue dispensing inlets are added through the inclined surface 8, glue can conveniently flow into the glue dispensing groove 7, and glue dispensing is convenient.

Example 4: a camera device, as shown in fig. 11, has the lens driving device described in embodiment 3, in the embodiment, the driving structure in the lens driving device drives the corresponding lens to move, so as to implement focusing, and after focusing, light enters the photoelectric sensor in the camera device through the lens and is converted into an electrical signal, so as to implement image conversion of a captured picture into electronic data, thereby implementing a camera function. The lens driving device and the spring structure in the camera device of this embodiment are fully described in the foregoing, and are not described herein again.

Example 5: an electronic product, as shown in fig. 12, has the camera device described in embodiment 4. The electronic device in this embodiment may be a mobile phone, a tablet computer, a telephone watch, a security camera, a vehicle-mounted camera, or the like, that is, the camera device in embodiment 4 is correspondingly installed in the electronic device, so as to achieve the function of taking a picture or recording a video.
