Abstract
The utility model discloses a novel voice coil motor limit structure, including spacing connecting block and stopper, spacing connecting block is bent and is connected on the voice coil motor shell, the stopper sets up the intermediate position in spacing connecting block bottom, and the even circumference of voice coil motor limit structure distributes on the voice coil motor shell, sets up 4 novel voice coil motor limit structure on each voice coil motor shell, the utility model discloses reduce the area of contact of stopper, guarantee the plane degree requirement of spacing face when effectively reducing the mould required precision to promote off -the -shelf yield, reduce cost.
Description
Technical field
The utility model relates to field of motors, especially a kind of novel voice coil motor position limiting structure.
Background technology
Existing voice coil motor great majority adopt shell spacing, four, its shell is to the Structure composing motor stroke limit structure of the similar claw of downward-extension, if there is larger error in the height of four claws, when motor movement is to position limiting structure position, its basic parameter particularly optical axis is more big changes, and optical axis is as the most important parameters of voice coil motor, if exceed permissible value, just become defective products.Existing claw structure adopts " mouth " font mostly, and its confined planes is comparatively large and due to the characteristic of drawing die, an independent confined planes is difficult to ensure flatness, and the flatness of four confined planes is difficult to ensure.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of novel voice coil motor position limiting structure, reduces the area of confined planes, effectively reduces the planarity requirements ensureing confined planes while mould and die accuracy requires, thus promotes the yield of finished product, reduce costs.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of novel voice coil motor position limiting structure, comprise spacing contiguous block and guide vane end stop, described spacing contiguous block bending is connected in voice coil motor case, and described guide vane end stop is arranged on the centre position bottom spacing contiguous block, and voice coil motor position limiting structure uniform circular is distributed in voice coil motor case.
Preferably, each voice coil motor case is arranged 4 novel voice coil motor position limiting structures.
Preferably, the ratio of described guide vane end stop length and spacing contiguous block length is 0.3 ~ 0.5.
Further, described spacing contiguous block two ends are provided with projection.
The beneficial effects of the utility model are:
The utility model connects spacing contiguous block by bending in voice coil motor case, spacing contiguous block lower end arranges guide vane end stop, contacted with motor finished product by guide vane end stop, compared to existing claw hollow structure, contact area reduces greatly, ensure that the planarity requirements of guide vane end stop and motor finished product contact-making surface while effectively reducing mould and die accuracy requirement, thus improve the yield of finished product, reduce cost.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is a kind of novel voice coil motor position limiting structure schematic diagram of the utility model.
Fig. 2 is a kind of novel voice coil motor position limiting structure cutaway view of the utility model.
In figure: 1, voice coil motor case, 2, spacing contiguous block, 3, projection, 4, guide vane end stop.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As depicted in figs. 1 and 2, the utility model discloses a kind of novel voice coil motor position limiting structure, comprise spacing contiguous block 2, guide vane end stop 4 and projection 3, the bending of described spacing contiguous block 2 is connected in voice coil motor case 1, described guide vane end stop 4 is arranged on the centre position bottom spacing contiguous block 2, the ratio of described spacing 4 length and spacing contiguous block 2 length is 0.3 ~ 0.5, in the present embodiment, ratio is 0.5, voice coil motor position limiting structure uniform circular is distributed in voice coil motor case 1, each voice coil motor case 1 is arranged 4 novel voice coil motor position limiting structures, described projection 3 is arranged on spacing contiguous block 2 two ends, projection 3 is for convenience of bending and molding.
The utility model compared with prior art, by replacing the hollow structure of claw with less guide vane end stop, reduce contact area, the required precision of effective reduction component, promote component and produce yield, ensure that motor finished product moves to qualifying bit postpone, its basic parameter can not be undergone mutation, thus promotes finished product yield.
Above-described the utility model execution mode, does not form the restriction to the utility model protection range.Any do within spirit of the present utility model and principle amendment, equivalent to replace and improvement etc., all should be included within claims of the present utility model.
Claims (4)
1. a novel voice coil motor position limiting structure, it is characterized in that, comprise spacing contiguous block and guide vane end stop, described spacing contiguous block bending is connected in voice coil motor case, described guide vane end stop is arranged on the centre position bottom spacing contiguous block, and voice coil motor position limiting structure uniform circular is distributed in voice coil motor case.
