Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are clearly and completely described with reference to the drawings in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the present embodiment provides a stable lifting device for a camera, which can effectively improve the lifting stability of the camera through an X-link assembly 14, and prevent the camera from shaking.

Specifically, this steady elevating gear includes lift rail 11 and X link assembly 14, and sliding connection has camera module 10 on lift rail 11. The X link assembly 14 includes an X link, a fixing base 142, and a lifting base 141 connected to the camera module 10. The fixing base 142 is stationary relative to the lifting rail 11, and the lifting base 141 can slide on the lifting rail 11 along with the camera module 10.

The X-link includes a first connecting rod 145 and a second connecting rod 146 which are arranged in a crossed manner, one end of the first connecting rod 145 is slidably connected with the lifting seat 141 through a first slider 143, and the other end is hinged to the fixing seat 142 to realize fixing. One end of the second connecting rod 146 is slidably connected to the fixing base 142 through the second sliding block 144, and the other end is hinged to the lifting base 141 to be fixed.

Thus, the operating principle of the X-link assembly 14 is: when the lifting seat 141 is lifted, the fixed seat 142 maintains the same position, so that the distance between the lifting seat 141 and the fixed seat 142 is changed, and at this time, one end of the first connecting rod 145 horizontally slides on the lifting seat 141 through the first slider 143, and one end of the second connecting rod 146 horizontally slides on the fixed seat 142 through the second slider 144. Practice proves that the lifting stability of the camera can be effectively improved and the camera is prevented from shaking by utilizing the X connecting rod assembly 14.

The X connecting rod is ultra-thin, the whole X connecting rod is only 7.5mm thick, and the X connecting rod has the advantages of small occupied space and light weight.

The lifting seat 141 is provided with a first sliding slot 1411 for the sliding connection of the first sliding block 143. This lift seat 141 is sheet metal component integrated into one piece, can realize ultra-thin and low cost's effect.

Similarly, the fixing base 142 is provided with a second sliding slot 1421 for the second sliding block 144 to slidably connect. This fixing base 142 is sheet metal component integrated into one piece, can realize ultra-thin and low cost's effect.

Since the first connecting rod 145 is a metal member, in order to prevent the metal member from directly rubbing against the first sliding groove 1411 to cause abrasion, the first sliding block 143 includes a first metal plate member 1431 and a first plastic member 1432. First plastic part 1432 is equipped with first parcel groove 14321, wraps up the both sides of first sheet metal component 1431 through two first parcel grooves 14321 to set up first plastic part 1432 and first spout 1411 into sliding connection. The first connecting rod 145 is hinged to the first sheet metal part 1431, and the first plastic part 1432 is slidably connected to the first sliding groove 1432, so that the first sliding block 143 of the structure has the advantage of low cost.

Similarly, in order to avoid the metal part from directly rubbing and wearing the second sliding groove 1421, the second sliding block 144 has the same structure as the first sliding block 143, and includes a metal plate and a plastic part. The second sliding block 144 is also slidably connected to the second sliding groove 1421 through a plastic member, so that the second sliding block 144 with this structure has an advantage of low cost.

As an optional manner of this embodiment, the lifting base 141 is provided with a first limiting member for limiting the maximum sliding stroke of the first slider 143. The two first limiting members are respectively located at two sides of the first sliding block 143. Similarly, a second limiting member for limiting the maximum sliding stroke of the second slider 144 is disposed on the fixing base 142. The two second limiting members are respectively located at two sides of the second sliding block 144.

The steady elevating gear of camera that this embodiment provided still includes electric drive module 15, can drive camera module 10 through electric drive module 15 and slide on lift rail 11.

Specifically, the electric drive module 15 includes a drive motor 153, the drive motor 153 is connected with a transmission gear 152 in a driving manner, the transmission gear 152 is meshed with a rack 151, the rack 151 is connected with the camera module 10, and the rack 151 is arranged along the sliding direction of the camera module 10. Therefore, when the driving motor 153 works, the driving gear 152 is driven to rotate forward and backward to drive the rack 151 to ascend and descend, so that the ascending and descending of the camera module 10 are realized.

As an optional manner of this embodiment, the camera module 10 may also be lifted and lowered by means of ejection. Specifically, the stable lifting device further comprises a locking hook 13, the locking hook 13 is connected with the camera module 10 and provided with a stop 131 for compressing the first elastic element 12, the stop 131 and the first elastic element 12 are sleeved on the guide shaft 16, and finally the locking hook 13 is limited to be lifted through the lifting unlocking module 20. The first elastic element 12 may alternatively be a spring.

Specifically, when the camera module 10 is ejected, the camera module 10 is pressed to descend, and the stopper 131 compresses the first elastic element 12 until the latch hook 13 is latched by the lift-latch release module 20. When the camera needs to be opened, the lifting unlocking module 20 is operated to release the locking hook 13, and the locking hook 13 is ejected and lifted under the action of the first elastic element 12, so that the camera module 10 is ejected and lifted quickly, the waiting time of a user is reduced, and the lifting stability of the camera module 10 can be ensured through the X-shaped connecting rod assembly 14 in the ejection process.

In another embodiment of the present application, there is also provided an electronic device including the stable lifting device for a camera provided in the above embodiment. The electronic equipment can be a mobile terminal with a camera, such as a mobile phone, and the camera module 10 is lifted through the stable lifting device, so that the lifting stability is better.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
