Specific embodiment
The utility model is more fully retouched below with reference to relevant drawings for the ease of understanding the utility model,
It states.The better embodiment of the utility model is given in attached drawing.But the utility model can come in many different forms
It realizes, however it is not limited to embodiments described herein.On the contrary, the purpose of providing these embodiments is that making practical new to this
The disclosure of type understands more thorough and comprehensive.
It should be noted that it can directly on the other element when element is referred to as " being fixed on " another element
Or there may also be elements placed in the middle.When an element is considered as " connection " another element, it, which can be, is directly connected to
To another element or it may be simultaneously present centering elements.Term as used herein " vertical ", " horizontal ", " left side ",
" right side " and similar statement for illustrative purposes only, are not meant to be the only embodiment.
Unless otherwise defined, all technical and scientific terms used herein are led with the technology for belonging to the utility model
The normally understood meaning of the technical staff in domain is identical.Terminology used in the description of the utility model herein only be
The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term " and or " used herein packet
Include any and all combinations of one or more related listed items.
As shown in Figure 1, Figure 2 and Figure 3, a kind of carrier structure 10 applied to VCM with dust reduction capability, including carrier body
100。
Carrier body 100 surround and is formed the square hollow cavity structure of both ends open, 110 face of side wall by side wall 110
There is the slot 120 that is screwed to the inner face of hollow cavity.In the present embodiment, hollow cavity is cylindrical shape, opens up and is screwed
Slot 120, for loading camera lens, camera lens is threadably secured slot 120 and realizes that rotation is fixed.
Referring to Figure 4 together, side wall 110 has the end face 130 with the central axis of hollow cavity, is located at end face 130
Edge offer the dust-proof groove 140 of " u "-shaped closed at one end open at one end.
Since carrier body 100 and other components cooperate small gap easy to form, extraneous dust is easy to pass through
This small gap and enter inside motor, the entrance of dust influences whether the smoothness of motor operations, reduces making for product
Use the service life.In order to more preferably solve this technical problem, carrier body 100 by offering dust-proof groove 140 on end face 130,
Extraneous dust can be effectively prevented to enter inside motor by gap, extraneous dust is needed by curved, complicated
Path get to inside motor, this increases dust to a certain extent and enters internal difficulty, in addition, dust-proof groove
140 also have the function of collecting dust, and dust is fallen in dust-proof groove 140, further improves dust-proof effect.
In the present embodiment, the quantity of dust-proof groove 140 is two, and two dust-proof grooves 140 are located at 130 phase of end face
Pair two edges.
In the second embodiment, the quantity of dust-proof groove 140 is two, and two dust-proof grooves 140 are located at end face
130 two adjacent edges.
In third embodiment, the quantity of dust-proof groove 140 is three, and three dust-proof grooves 140 are located at end face
130 wherein three edges.
In the 4th embodiment, the quantity of dust-proof groove 140 is four, and four dust-proof grooves 140 are located at end face
130 four edges.
The number of dust-proof groove 140 is correspondingly arranged according to specific product type, as long as can reach dust-proof effect.
Further, there is the barricade 150 for the port setting for being surrounded on hollow cavity, barricade 150 protrudes from end face 130
End face 130, barricade 150 are arranged close to hollow cavity side, and dust-proof groove 140 is arranged far from hollow cavity side.Due to barricade
150 protrude from end face 130, and extraneous dust gets to dust-proof groove 140 firstly the need of crossing barricade 150, and dust-proof groove
140 form curved path, and dust-proof groove 140 has dust collecting function, such structure design, so that extraneous dust
It will be difficult to enter inside motor, and greatly improve the dust-proof effect of carrier.
The carrier structure 10 for being applied to VCM and having dust reduction capability of the utility model, passes through the structure to carrier body 100
It optimizes, dust-proof groove 140 is especially offered on end face 130, reduce the gap that extraneous dust passes through carrier
A possibility that entering inside motor, improves dust-proof effect, improves the smoothness of motor operations, and that improves product uses the longevity
Life.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
