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 3, in the embodiment, a ratchet mechanism 18 is used to separate a driving member 19 from a transmission mechanism 15, so as to avoid rigid connection between the driving member 19 and the transmission mechanism 15, so that the camera module 10 can bear large external impact, the service life of the lifting device is prolonged, and a foundation is provided for rapidly closing the camera module 10.

Specifically, the lifting device comprises a lifting guide rail 11, and the lifting guide rail 11 is connected with a camera module 10 in a sliding manner.

The driving member 19 (which may be a motor) is connected to a ratchet mechanism 18, the ratchet mechanism 18 is connected to a transmission mechanism 15, and the transmission mechanism 15 is used for driving the camera module 10 to descend.

Ratchet mechanism 18 includes a pawl 181 and a ratchet 182, ratchet 182 coupled to pawl 181 and driver 19 coupled to pawl 181.

The transmission mechanism 15 includes a driving wheel 151, and the driving wheel 151 is mounted on the ratchet 182 to be fixed. The driving wheel 151 is connected with the first driving wheel 152 in a meshing manner, the first driving wheel 152 is provided with a first meshing tooth 1521 and a second meshing tooth 1522, and the first meshing tooth 1521 is meshed with the driving wheel 151. The second meshing tooth 1522 is in meshing connection with the second transmission wheel 153, and the second transmission wheel 153 is meshed with the second meshing tooth 1522. The second transmission wheel 153 is also engaged with a rack 154, and the rack 154 is connected with the camera module 10.

Therefore, the elevating gear of camera that this embodiment provided, its theory of operation is:

when the camera is closed, the driving piece 19 drives the pawl 181 to rotate anticlockwise, and the ratchet wheel 182 rotates along with the pawl; the driving wheel 151 rotates counterclockwise and drives the first driving wheel 152 to rotate clockwise through the first engaging tooth 1521, and then drives the second driving wheel 153 to rotate counterclockwise through the second engaging tooth 1522, so as to drive the rack 154 to move downward, thereby achieving the descending of the camera module 10.

Because the ratchet mechanism 18 is a unidirectional motion mechanism, when the camera module 10 descends, even if the camera module 10 is subjected to external impact (such as pressing the camera module 10), the transmission mechanism 15 is not damaged, the service life of the lifting device is prolonged, and a foundation is provided for realizing quick closing of the camera module 10.

Referring to fig. 4 to 8, in another embodiment of the present application, a lifting device for a camera is provided, which can achieve rapid lifting of the camera by means of ejection, and the lifting device is not easily damaged.

The lifting device further comprises a locking hook 13, the locking hook 13 being provided with a stop 131 for compressing the first elastic element 12.

When the camera module 10 is retracted into the electronic device, the first elastic element 12 is compressed by the stopper 131, and the movement of the latch hook 13 needs to be limited; when the camera needs to be opened, the movement of the locking hook 13 needs to be unlocked, so that the locking hook 13 can move upwards, and the camera module 10 can be quickly ejected out under the elastic action of the first elastic element 12.

In order to achieve the restriction and the release of the movement of the restriction latch 13, the lifting apparatus further includes a lifting unlocking module 20. This lift unblock module 20 includes PMKD 21 and apron 22, and it is connected with unlock switch 23 to rotate on PMKD 21, and the bottom of camera module 10 and the left side end of unlock switch 23 are connected respectively to the both ends of latch hook 13. The fixed bottom plate 21 is further provided with a toggle switch 25, and the toggle switch 25 is rotatably connected with the fixed bottom plate 21 and used for limiting and releasing the rotation of the limiting and unlocking switch 23.

when the camera is started, the rotation of the unlocking switch 23 is released by operating the toggle switch 25, at this time, the first elastic element 12 releases the elastic force, the lock hook 13 is ejected and ascended rapidly under the action of the elastic force, and meanwhile, the unlocking switch 23 rotates, so that the camera module 10 is driven to ascend rapidly along the lifting guide rail 11. In order to prevent the ratchet mechanism 18 from affecting the opening of the camera, the cam can be opened, and the pawl 181 is driven by the driving member 19 to rotate clockwise, so that the camera can be ejected smoothly.

The lifting device of camera that this embodiment provided can pop out camera module 10 through first elastic element 12 fast, reduces user waiting time, improves user experience and feels to can bear great external impact, make lifting device not fragile.

In order to enable the unlocking switch 23 to be reset smoothly, the lifting device of the camera further comprises a second elastic element 24, wherein the fixed end of the second elastic element 24 is connected with the fixed bottom plate 21, and the free end of the second elastic element is connected with the right side end of the unlocking switch 23.

After unlocking, the electromagnet 26 is de-energized and the toggle switch 25 is reset under the action of the third elastic element 28
