The technical scheme of the utility model is that:
the utility model provides a voice coil motor strenghthened type damping structure, includes motor housing, carrier and base, motor housing's top surface center is equipped with the hole of dodging that corresponds and wait to assemble the camera lens, and its technical essential is: the inner wall of the avoidance hole is provided with a plurality of inner flanges extending into the motor shell, the side of the carrier facing the top surface of the motor shell is provided with an upper groove corresponding to the inner flanges, and the inner flanges are inserted into the upper groove and form glue dispensing spaces with the inner side walls of the upper groove; the surface of the carrier, which faces the base, is provided with a plurality of lower grooves, damping glue is pre-filled in the lower grooves, damping terminals are vertically arranged at positions of the base, which correspond to the lower grooves, and the top ends of the damping terminals are inserted into the damping glue in the lower grooves.
In the voice coil motor reinforced damping structure, the number of the upper grooves and the number of the lower grooves are four respectively.
According to the voice coil motor reinforced damping structure, the inner flanging is parallel to the central line of the carrier, and the inner side wall, close to the central line of the carrier, of the upper groove is provided with the glue dispensing surface parallel to the inner flanging and used for bearing damping glue.
In the voice coil motor reinforced damping structure, the shape of the avoiding hole at the inner flanging is U-shaped, and the inner flanging is connected with the U-shaped bottom section so as to avoid interference in assembling the lens.
Foretell voice coil motor strenghthened type damping structure, the position both sides that the inside flanging inserted in the upper groove are equipped with the extension face respectively, and the extension face end draws in to dodging hole center side, the extension face of inside flanging and both sides forms the concave surface that bears the weight of the damping and glue, and the setting of this concave surface does benefit to the magnetic field intensity that strengthens voice coil motor simultaneously.
Foretell voice coil motor strenghthened type damping structure, the damping terminal is the metal terminal, is L shape, and its horizontal segment inlays in the base.
The utility model has the advantages that:
1. because motor housing has set up the inside flanging, and the carrier has set up the upper groove that corresponds with the inside flanging, and the inside flanging inserts in the upper groove and is connected with usable damping glue between the recess inside wall for voice coil motor coil carrier shock attenuation is used, makes the cell-phone can the rapid stabilization get off at the in-process of shooing, realizes the purpose of focusing fast. Compared with the prior art, the adhesive dispensing position is external, and the adhesive dispensing position is replaced between the inner flanging and the inner side wall of the groove. The glue dispensing space reserved inside the voice coil motor product is saved, the problem that the occupied space of the existing glue dispensing type damping structure inside the motor is large is solved, the limitation of the design space is broken through, the structure is simple and compact, and the application cost is low.
2. Because the glue dispensing position formed by the inner flanging and the upper groove is external, the glue dispensing process can be carried out after the voice coil motor is formed, the production process is easy to realize, and the equipment debugging is convenient. Because the point is glued the position and is externally arranged, the equipment is accomplished the back, washs whole product earlier, glues at last between inside flanging and the last recess point, and greatly reduced damping is glued because of the inefficacy risk that the washing leads to, makes damping stable in structure, excellent in use effect, long service life reduces the product loss rate, reduces man-hour, improves the productivity.
3. Adopt damping terminal and low groove and fill damping glue in advance to form the shock-absorbing structure to the base side, strengthened the damping function, further strengthened the cushioning effect. Meanwhile, the prefilled damping rubber is positioned in the lower groove, and is washed downwards from the side of the shell ceiling during washing, washing water only slightly enters the shell, the probability of back-flowing the washing water is extremely low due to the structural design of the lower groove, the difficulty that the washing water enters the gap between the damping rubber and the lower groove in a reverse flow mode is high, and the failure risk of the damping rubber caused by washing is greatly reduced.
