Fig. 1 is the schematic diagram that a kind of driving structure 100 is shown according to an exemplary embodiment.As shown in Figure 1, the driving knot
Structure 100 can be used for that target object is driven to be moved.For example, which may include being located in electronic equipment
Deck, the deck, by the cooperation of driving structure 100 and deck, can drive deck to set relative to electronics for assembling SIM card
Standby shell is stretched out or is retracted；Or as shown in Fig. 2, the driving structure 100 can be configured to camera module 200,
The camera module 200 may include CCD camera assembly 201, which can cooperate with driving structure 100, such as
Shown in Fig. 3, to drive shell of the CCD camera assembly 201 relative to electronic equipment belonging to camera module 200 by driving structure 100
Opposite sliding, specifically can be CCD camera assembly 201 and matches with driving structure 100, so that driving structure 100 between body 301
The power of output can be passed to CCD camera assembly 201, and the CCD camera assembly 201 is driven to be slided relative to shell 301.
For example, under the driving of driving structure 100, can by between CCD camera assembly 201 and shell 301 from shown in Fig. 3
State switches to state shown in Fig. 4；Alternatively, by Fig. 3 is switched to from state shown in Fig. 4 between CCD camera assembly 201 and shell 301
Shown state.Wherein, under state shown in Fig. 3, camera module 200 is located at the inside of shell 301, is in receiving state；Fig. 4 institute
Show under state, camera module 200 stretches out in shell 301, is in stretching state, can get external image information.
Specifically, as shown in Figs 1-4, driving structure 100 may include driving main body 1 and lead screw assembly 2, driving master
Body 1 may include power output shaft (not shown), lead screw assembly 2 and the directly cooperation of driving main body 1 (i.e. driving main body 1 and
There is direct connection relationship) between power output shaft.Wherein, the target object driven using driving structure 100 is camera group
For part 201, one end of lead screw assembly 2 can be connect with power output axis connection, the other end and CCD camera assembly 201.With this,
When power output shaft rotation, lead screw assembly 2 is translated, and further CCD camera assembly 201 is pushed to slide relative to shell 301, cut
Change the relative positional relationship between CCD camera assembly 201 and shell 301.
Certainly, in another embodiment, can also cooperate indirectly between power output shaft and lead screw assembly 2, for example, as schemed
Shown in 5, camera module 200 can also include drive mechanism 3, the drive mechanism 3 be located at lead screw assembly 2 and power output shaft it
Between, to be transferred to lead screw assembly 2 by the output power power of axis output of drive mechanism 3, so that lead screw assembly 2 is mobile.With
This, carries out movement transmitting by drive mechanism 3, can reduce to the layout requirements between lead screw assembly 2 and driving main body 1, rich
The topology layout mode of rich camera module 200 is conducive to optimize the inner space of electronic equipment.
As can be seen from the above embodiments, in disclosed technique scheme, pass through target object, lead screw assembly 2 and driving main body 1
Cooperation, the location of switching target object that can be multi-faceted promote the technology sense of electronic equipment；Moreover, in the disclosure
It can be cooperated using indirect or direct mode between lead screw assembly 2 and driving main body 1, can reduce to lead screw assembly
Layout requirements between 2 and driving main body 1, enrich the topology layout mode of camera module 200, are conducive to electronic equipment
Inner space optimizes.
For the mode cooperated indirectly between the lead screw assembly 2 proposed in above-described embodiment and driving main body 1, still with target
Object be CCD camera assembly 201 for illustrate.
It as shown in Figure 5, Figure 6, can be with laid out in parallel, i.e., as shown in Figure 6, lead screw between lead screw assembly 2 and driving main body 1
The direction shown in the arrow A is arranged between component 2 and driving main body 1, and one end of drive mechanism 3 and power output shaft connect
It connects, the connection of the other end and lead screw assembly 2, and the movement direction of transfer of drive mechanism 3 is perpendicular to driving main body 1 and lead screw assembly 2
Direction side by side, i.e. the movement direction of transfer of drive mechanism 3 realizes driving main body 1 arranged side by side perpendicular to direction shown in arrow A
Movement transmitting between lead screw assembly 2.
In the present embodiment, lead screw assembly 2 and driving 1 laid out in parallel of main body, are realized using drive mechanism 3 in direction side by side
On movement transmitting, enrich the structural arrangement mode of camera module 200, be conducive to the compact-sized of camera module 200
Change, especially after being assembled to electronic equipment, increases the layout pattern between camera module 200 and other electronic components, have
The limited arrangement space of electronic equipment internal is utilized conducive to reasonable.
For example, still with shown in Fig. 5, Fig. 6, drive mechanism 3 can be located at the identical of driving main body 1 and lead screw assembly 2

The left side of lead screw main body 21 or as shown in Figure 4, the second guide post 4 can also be located at the right side of lead screw main body 21, specifically can be with
It is designed as needed with layout requirements, the disclosure is limited not to this.
It can be slidably connected between second guide post 4 and stroke push rod 22.For example, as shown in fig. 6, the both ends of stroke push rod 22
Matching hole can be respectively set.Wherein, spiral shell can be set in the one end fits hole connecting on stroke push rod 22 with lead screw main body 21
Line or assembly inner nut, so that lead screw main body 21 and stroke push rod 22 are rotatablely connected, by the rotary motion of lead screw main body 21
It is converted into the translational motion of stroke push rod 22；Connect on stroke push rod 22 with the second guide post 4 one end fits hole and the second guide post 4 it
Between can be transition fit, avoid occurring the case where stuck or Caton between stroke push rod 22 and the second guide post 4, guarantee stroke
Push rod 22 can be translated along the setting direction of the second guide post 4.
Wherein, the second guide post 4 may include diversified forms relative to the fixation of shell 301, in one embodiment, can be
Two guide posts 4 are secured directly on shell 301.Alternatively, in another embodiment, the second guide post 4 is also possible to indirectly opposite
It is fixed in shell 301.For example, as shown in Figure 5, Figure 6, driving structure 100 can also include the fixation bracket for being fixed on shell 301
5, it is fixedly connected between the second guide post 4 and fixed bracket 5.Certainly, it in some other embodiment, also can be set and shell
301 other brackets being fixedly connected, the second guide post 4 are fixedly connected with the bracket.About the second guide post 4, no doubt there is likely to be it
His fixed form, this is no longer going to repeat them.
It in further embodiments, can also translation in such a way that sliding slot and sliding rail are cooperated to stroke push rod 22
It is limited.For example, in one embodiment, stroke push rod 22 may include being located on stroke push rod 22 towards shell 301
The sliding slot of side the sliding rail with sliding slot cooperation can be set on shell 301, by the cooperation between sliding rail and sliding slot, to stroke
Push rod 22 is limited relative to the movement of shell 301.Alternatively, in another embodiment, being also possible to the shape on fixed bracket 5
At the sliding rail matched with sliding slot, the limit mobile to stroke push rod 22 is realized.Certainly, herein only with the shape on stroke push rod 22
At being illustrated for sliding slot, naturally it is also possible to sliding rail is formed on stroke push rod 22, on shell 301 or fixed bracket 5
Sliding slot is formed, the disclosure is limited not to this.
In the technical solution of the disclosure, driving main body 1 may include motor 11, and power output shaft can be set in the electricity
On machine 11；Alternatively, increasing active force of the driving main body 1 to lead screw assembly 2, this public affairs to improve the output torque of driving main body 1
