The following describes a lifting process of the camera device 200 with the initial position of the camera device 200 in the retracted state.

Illustratively, as shown in fig. 8, as the rotary cylinder 230 rotates about the lifting cylinder 240 in a first direction (i.e., the direction from the first plane 2331 to the second plane 2332), the distance between the guide rail 233 and the base 212 becomes gradually greater, and since the first buffer 261 is compressively restrained between the lifting cylinder 240 and the base 212, the restoring force of the first buffer 261 drives the lifting cylinder 240 to rise in the Z direction, and as the rotary cylinder 230 rotates from the second plane 2332 to the first plane 2331, the bump 241 also rises from the second plane 2332 to the first plane 2331 along the guide rail 233, thereby bringing the lifting cylinder 240 from the retracted state to the extended state (see fig. 9).

As shown in fig. 8, when the rotary cylinder 230 rotates around the lifting cylinder 240 in the second direction (the direction from the second plane 2332 to the first plane 2331), the distance between the guide rail 233 and the base 212 becomes gradually smaller, and since the guide rail 233 of the rotary cylinder 230 contacts the top end of the projection 241, the guide rail 233 drives the projection 241 to descend in the Z direction, thereby driving the lifting cylinder 240 to descend in the Z direction, and when the rotary cylinder 230 rotates from the first plane 2331 to the second plane 2332, the projection 241 also descends from the first plane 2331 to the second plane 2332 along the guide rail 233, thereby causing the lifting cylinder 240 to reach the retracted state from the extended state. The first direction may be a clockwise direction, and the second direction may be a counterclockwise direction.

The whole driving process of the camera device 200 is that the driving component 280 drives the rotating cylinder 230 to rotate, and the rotating cylinder 230 drives the lifting cylinder 240 to reciprocate along the Z direction, and the lifting cylinder 240 can drive the camera module 220 to reciprocate along the Z direction because the camera module 220 is arranged on the lifting cylinder 240.

It should be noted that, the connection manner between the camera module 220 and the lifting cylinder 240 does not limit the protection scope of the technical solution of the present application, as long as the camera module 220 can move along with the lifting cylinder 240. Illustratively, the connection between the camera module 220 and the lifting cylinder 240 may be adhesive or the like.

The buffering function of the camera device 200 is specifically described below.

In this embodiment, due to the arrangement of the first buffer member 261, the external force impact suffered by the camera device 200 can be effectively alleviated, so that the problem of lifting jam or jamming of the camera module 220 can be avoided, the stability and reliability of the lifting camera device 200 are improved, the service life of the camera device 200 is prolonged, and the service life of the electronic device 100 is further prolonged.

As shown in fig. 9 and 10, the first buffer member 261 is sleeved on the guide rod 251, the lifting cylinder 240 is also sleeved on the guide rod 251, wherein a mounting groove 243 for accommodating the guide assembly 250 is arranged on the cylinder wall of the lifting cylinder 240, the mounting groove 243 extends downwards from one end of the lifting cylinder far away from the carrier 210, a through hole 2432 for the guide rod 251 to pass through is arranged on the groove bottom wall 2431 of the mounting groove 243, and a accommodating cavity 2433 for accommodating the first buffer member 261 is arranged at one end of the groove bottom wall 2431 near the carrier 210; illustratively, the number of the mounting slots 243 may be plural, and the plurality of mounting slots 243 are provided on the lift cylinder 240 at intervals. Wherein the number of the mounting slots 243 may be three, four, five or more, and the number of the mounting slots 243 is not limited. The distribution of the mounting slot 243 and the first buffer 261 can be set to be axisymmetric, centrosymmetric, asymmetric, etc. according to the actual space.

In the present embodiment, three mounting slots 243 are disposed on the lifting cylinder 240, the three mounting slots 243 are disposed on the lifting cylinder 240 at intervals, and the three mounting slots 243 are uniformly disposed on the lifting cylinder 240. And only one through hole 2432 is provided in one mounting groove 243, one guide rod 251 is provided in each through hole 2432, wherein at least one first buffer member 261 may be provided on each guide rod 251, and illustratively, one, two, three or more first buffer members 261 may be provided on each guide rod 251.

It should be noted that, in other embodiments, two, three or more through holes 2432 may be disposed on one mounting slot 243, and one guide rod 251 may be disposed in each through hole 2432, that is, the number of through holes 2432 is the same as the number of guide rods 251, and the number of through holes 2432 and the number of guide assemblies 250 on the mounting slot 243 are not particularly limited in the embodiments of the present application.

In this embodiment, the bottom end of the first buffer member 261 is in contact with the base 212, the top end of the first buffer member 261 is in contact with the bottom wall 2431 of the mounting groove on the lifting cylinder 240, and the first buffer member 261 is in a compressed state when the camera device is in the extended state and the retracted state, that is, the first buffer member 261 is always in a compressed state, so that the first buffer member 261 always has an outward restoring force.

It should be noted that, by setting the state of the first buffer member 261 to be always in the compressed state, the first buffer member 261 always has an upward pushing force (i.e. a restoring force of the spring) on the lifting cylinder 240, so that when the constraint of the lifting cylinder 240 along the Z direction (i.e. the constraint of the guide rail 233 of the rotating cylinder 230 on the bump 241) disappears, the lifting cylinder 240 can drive the camera module 220 to move upward along the guide rod 251 under the pushing force, and also will not move downward along the guide rod 251 due to self gravity or external force impact when the camera device 200 is in the extended state.

It can be understood that when the camera device 200 is impacted by the external force F, the light transmitting member 293 is firstly acted on the protective cover 292, and the light transmitting member 293 is disposed on the protective cover 292 and is fixedly connected with the lifting cylinder 240, so that the external force impact on the camera device 200 acts on the protective cover 292 through the light transmitting member 293 and then acts on the lifting cylinder 240 through the protective cover 292, and the first buffer member 261 is compressed due to the first buffer member 261 being disposed at the bottom end of the lifting cylinder 240, so as to buffer the external force impact on the camera device 200. The external impact is not applied to the camera module 220 all the time during the whole buffering process, and the impact is not applied to the lifting cylinder 240 and the rotating cylinder 230, so the first buffer 261 can protect the camera device 200.

In addition, when the camera device 200 is in the retracted state, at the moment when the rotary cylinder 230 is started, the limitation of the guide rail 233 on the rotary cylinder 230 on the bump 241 of the lifting cylinder 240 disappears, and the lifting cylinder 240 moves upward along with the guide rail 233 under the restoring force of the first buffer 261. In the above process, the lifting cylinder 240 is not directly subjected to the acting force of the rotating cylinder 230, but the restoring force of the first buffer member 261 generates an upward pushing force on the lifting cylinder 240, and the bump 241 and the guide rail 233 are always in contact state due to the restoring force, so that the instant starting of the rotating cylinder 230 will not cause instant impact on the lifting cylinder 240, and further the camera device 200 is protected.

Therefore, as long as the camera module 220 is to be extended, is being extended or has been extended out of the electronic device 100, whether the camera module 220 is extended out or retracted in, or in a normal working state, the first buffer member 261 can play a role in buffering, and the first buffer member 261 can realize the whole-course buffering of the movement process and the working process of the camera module 220, so that the protection effect on the camera module 220 is better.

In this embodiment, the guide rod 251 of the guide assembly 250 is used to mount the first buffer member 261, and can also guide the lifting cylinder 240, so as to effectively prevent the lifting cylinder 240 from rotating relative to the base 212.

The connection between the guide bar cap 252 and the guide bar 251 is not limited in the embodiment of the present application, as long as the guide bar cap 252 and the guide bar 251 can be fixedly connected. Illustratively, the guide bar cap 252 and the guide bar 251 may be fixedly connected by welding, riveting, or screwing, etc., and may be specifically set according to the specific situation, and is not specifically limited in this embodiment.

The three guide assemblies 250 are arranged along the circumferential direction of the base 212 at intervals, and the corresponding included angles between two adjacent guide assemblies 250 are the same, namely, the three guide assemblies 250 are uniformly arranged on the circumferential direction of the base 212, that is, the first buffer parts 261 are uniformly arranged on the circumferential direction of the base 212, so that the stress of the lifting cylinder 240 is uniform, the lifting cylinder 240 can not deviate in the lifting or descending process, and the problem of jamming in the lifting process is reduced. Of course, in some embodiments, the number of guide assemblies 250 may also be one, two, four, five, six, or more, and the number of guide assemblies 250 is not limited.

Of course, in some embodiments, the plurality of first cushioning members 261 may be axially symmetrically distributed, or may be asymmetrically distributed, and the distribution of the first cushioning members 261 is not specifically limited in this embodiment. Of course, it is understood that the distribution of the guide assemblies 250 may be the same as the distribution of the first buffers 261.
