The top end surface of the bump 241 is in contact with the end surface of the guide rail 233, and when the bump 241 is located on the first plane 2331 , the lifting tube 240 is in an extended state, that is, the camera device 200 is in an extended state. When the bump 241 is located on the second plane 2332, the lifting tube 240 is in a retracted state, that is, the camera device 200 is in a retracted state.

For example, the cross section of the bump 241 in the axial direction of the rotating cylinder 230 can be a parallelogram shape with four rounded corners. This can make the top end surface of the bump 241 have a planar structure, and the two ends of the plane can be Curved surface, this can make the bump 241 and the guide rail 233 cooperate smoothly, avoid the wear and scratching of the bump 241 on the guide rail 233, thereby prevent lifting jamming, and extend the service life of the bump 241 and the guide rail 233. Of course, the bumps 241 can also have other shapes, such as a cylinder with a flat top end surface, a rectangular parallelepiped with rounded corners, etc. The shape of the bumps 241 is not specifically limited in the embodiment of the present application.

It should be noted that the end surface of the guide rail 233 can be perpendicular to the side wall of the rotating cylinder 230, or inclined toward the end close to the base 212, so that when the bump 241 slides along the guide rail 233, the bump 241 can be prevented from sliding off the guide rail 233. out. In addition, an end of the guide rail 233 close to the center of the rotating drum 230 can also be provided with a rib (not shown in the figure) extending close to the base 212, which can further ensure that the bump 241 will not slide out of the guide rail 233. Of course, the guide rail 233 can also be configured in other shapes, which are not specifically limited in the embodiment of the present application.

As shown in FIG. 8 , the distance between the first plane 2331 and the second plane 2332 in the axial direction of the rotating cylinder 230 is the first distance L _{1 , and the first distance L 1} _is the distance at which the lifting tube 240 can rise or fall along the Z direction. Distance; the distance between the end of the first plane 2331 away from the second plane 2332 and the end of the second plane 2332 away from the first plane 2331 in the circumferential direction of the rotating drum 230 is the second distance L ₂ , and the rotating drum 230 rotates through a second distance L _2. The lifting tube 240 can be raised or lowered by a first distance L ₁ along the Z direction. In addition, a rack 231 is provided on the outside of the rotating cylinder 230, and the rack 231 is provided at one end of the rotating cylinder 230 close to the base 212 to facilitate the meshing connection of the driving assembly 280; the length of the rack 231 in the circumferential direction of the rotating cylinder 230 is L ₃ is greater than or equal to the second distance L ₂ . The end of the first plane 2331 away from the second plane 2332 and the end of the second plane 2332 away from the first plane 2331 are both provided with blocking walls 2333; the blocking walls 2333 extend in a direction away from the guide rail, and the blocking walls 2333 are used to limit the movement of the bumps on the guide rails. Inside.

It should be noted that the rack 231 in the embodiment of the present application means that the outer circumference of the rotating drum 230 is provided with teeth that can be meshed with the gear, but the portion of the outer circumference of the rotating drum 230 that is provided with teeth is less than one circle.

By arranging the first plane 2331 and the second plane 2332, the bump 241 can be engaged at the first plane 2331 or the second plane 2332, so that the lifting tube 240 is in a stable state when it is extended or retracted. , this can prevent the lifting tube 240 from sliding along the guide rail 233, thereby preventing the camera device 200 from shaking, so as to ensure the shooting effect of the camera device 200.

It should be noted that the length of the first plane 2331 and the second plane 2332 only needs to be greater than or equal to the length of the top end surface of the bump 241. The specific lengths of the first plane 2331 and the second plane 2332 can be set according to specific circumstances. There is no specific limitation in this embodiment.

In some embodiments, the number of grooves 232 may be multiple, that is, the number of guide rails 233 may be multiple; multiple guide rails 233 are arranged at intervals inside the rotating drum 230, and the multiple guide rails 233 may be evenly distributed on the inside of the rotating drum 230. The inside of 230 can be specifically set according to the distribution of the bumps 241. In addition, the number of guide rails 233 is the same as the number of bumps 241, and the distances from the plurality of bumps 241 to the base 212 are all the same, so that the lifting tube 240 can receive a uniform force and can rise or fall stably. Of course, the number of guide rails 233 and bumps 241 does not limit the scope of protection of the technical solution of the present application. One guide rail 233 can correspond to one bump 241, or one guide rail 233 can correspond to one bump 241. A bump 241 can be set according to the actual situation.

The lifting process of the camera device 200 will be described below with the initial position of the camera device 200 being the retracted state.

For example, as shown in FIG. 8 , when the rotating cylinder 230 rotates around the lifting cylinder 240 along the first direction (ie, the direction from the first plane 2331 to the second plane 2332 ), the distance between the guide rail 233 and the base 212 gradually increases. becomes larger, since the compression of the first buffer member 261 is limited between the lifting tube 240 and the base 212, the restoring force of the first buffer member 261 will drive the lifting tube 240 to rise along the Z direction. When the rotating tube 230 moves from the second plane 2332 When rotating 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 causing the lifting tube 240 to move from the retracted state to the extended state (see Figure 9).

As shown in FIG. 8 , when the rotating drum 230 rotates around the lifting tube 240 along 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 gradually becomes smaller. The guide rail 233 of 230 is in contact with the top of the bump 241, so the guide rail 233 will drive the bump 241 to descend along the Z direction, and then drive the lifting tube 240 to descend along the Z direction. When the rotating tube 230 rotates from the first plane 2331 to the second When reaching the plane 2332, the bump 241 also descends from the first plane 2331 to the second plane 2332 along the guide rail 233, thereby causing the lifting tube 240 to move from the extended state to the retracted state. The first direction may be clockwise, and the second direction may be counterclockwise.

The entire driving process of the camera device 200 is that the driving assembly 280 drives the rotating drum 230 to rotate, and the rotating drum 230 drives the lifting tube 240 to reciprocate in the Z direction. Since the camera module 220 is arranged on the lifting tube 240, the lifting tube 240 can be driven. The camera module 220 reciprocates along the Z direction.

It should be noted that the connection method between the camera module 220 and the lifting tube 240 does not limit the scope of protection of the technical solution of this application, as long as the camera module 220 can move together with the lifting tube 240 . For example, the connection method between the camera module 220 and the lifting tube 240 may be bonding or the like.

The buffering function of the camera device 200 will be introduced in detail below.

In this embodiment, due to the arrangement of the first buffer 261, the impact of external forces on the camera device 200 can be effectively alleviated, thereby avoiding the problem of the camera module 220 being stuck or stuck in lifting and lowering, and improving the stability of the lifting and lowering of the camera device 200. performance and reliability, extending the service life of the camera device 200, and thereby extending the service life of the electronic device 100.

As shown in FIGS. 9 and 10 , the first buffer member 261 is sleeved on the guide rod 251 , and the lifting tube 240 is also sleeved on the guide rod 251 . The cylinder wall of the lifting cylinder 240 is provided with a hole for accommodating the guide assembly 250 . The installation slot 243 extends downward from the end of the lifting tube away from the bearing member 210. The bottom wall 2431 of the installation slot 243 is provided with a through hole 2432 for the guide rod 251 to pass through. An accommodating cavity 2433 for accommodating the first buffer member 261 is provided at one end of 2431 close to the bearing member 210; for example, the number of installation slots 243 may be multiple, and the multiple installation slots 243 are spaced apart on the lifting tube 240. The number of installation slots 243 may be three, four, five or more, and the number of installation slots 243 is not limited. Among them, the distribution of the installation slots 243 and the first buffer member 261 can be set to various types such as axial symmetry, center symmetry, asymmetry, etc. according to the actual space.

In this embodiment, a total of three installation slots 243 are provided on the lifting tube 240 . The three installation slots 243 are arranged on the lifting tube 240 at intervals, and the three installation slots 243 are evenly arranged on the lifting tube 240 . And there is only one through hole 2432 provided in one installation slot 243, and a guide rod 251 is provided in each through hole 2432, wherein at least one first buffer member 261 can be provided on each guide rod 251. For example, each One, two, three or more first buffer members 261 may be provided on the guide rod 251.

It should be noted that in other embodiments, one installation slot 243 can also be provided with two, three or or more through holes 2432, and each through hole 2432 can be provided with a guide rod 251. That is to say, the number of through holes 2432 is the same as the number of guide rods 251. In the embodiment of the present application, the installation slot 243 The number of through holes 2432 and the number of guide assemblies 250 are not specifically limited.

In this embodiment, the bottom end of the first buffer member 261 is in contact with the base 212, and the top end of the first buffer member 261 is in contact with the bottom wall 2431 of the installation slot on the lifting tube 240, and the first buffer member 261 is in contact with the camera. The device is in a compressed state when it is in an extended state and a retracted state, that is to say, 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 always be in a compressed state, the first buffer member 261 can always have an upward thrust (ie, the restoring force of the spring) on the lifting tube 240, so that during the lifting When the restraint of the barrel 240 along the Z direction (that is, the restriction of the bump 241 by the guide rail 233 of the rotating barrel 230) disappears, the lifting barrel 240 can drive the camera module 220 to move upward along the guide rod 251 under the action of the thrust force. When the camera device 200 is in the extended state, it will not move downward along the guide rod 251 due to its own gravity or external impact.

It can be understood that when the camera device 200 is impacted by the external force F, it will first act on the light-transmitting member 293, and the light-transmitting member 293 is provided on the protective cover 292, and the protective cover 292 is fixedly connected to the lifting tube 240, so in 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 tube 240 through the protective cover 292. Since the bottom end of the lifting tube 240 is provided with a first buffer member 261, the first buffer member 261 is provided at the bottom end of the lifting tube 240. The member 261 is compressed, thereby buffering the camera device 200 from external force impact. During the entire buffering process, external impact will never act on the camera module 220, and will not cause impact on the lifting tube 240 and the rotating tube 230. Therefore, the first buffering member 261 can protect the camera device 200.

In addition, when the camera device 200 is in the retracted state, the moment the rotating tube 230 is started, the restriction of the convex block 241 of the lifting tube 240 by the guide rail 233 on the rotating tube 230 disappears, and the lifting tube 240 is affected by the restoring force of the first buffer member 261. It moves upward along with the guide rail 233. During the above process, the lifting cylinder 240 does not directly receive the force of the rotating cylinder 230, but the restoring force of the first buffer member 261 generates an upward thrust on the lifting cylinder 240. Since the restoring force always exists, the bumps 241 and The guide rail 233 is always in contact, so the instantaneous start of the rotating cylinder 230 will not cause an instantaneous impact on the lifting cylinder 240, thereby protecting the camera device 200.

Therefore, as long as the camera module 220 is about to extend, is extending, or has extended out of the electronic device 100, whether it is the process of the camera module 220 extending outwards, the process of retracting inward, or the normal working state, the first The buffering members 261 can all play a buffering role. The first buffering member 261 can buffer the entire movement process and working process of the camera module 220, and has a better protection effect on the camera module 220.

As shown in FIG. 10 , the guide rod cap 252 is fixedly arranged on the top of the guide rod 251 , and the lifting cylinder can reciprocate along the guide rod 251 between the guide rod cap 252 and the base in the Z direction. The guide rod cap 252 is used to limit the lifting tube 240 when the lifting tube 240 is in an extended state, thereby preventing the lifting tube 240 from sliding out from the top of the guide rod 251 .

In this embodiment, the guide rod 251 in the guide assembly 250 is used to install the first buffer member 261 on the one hand, and on the other hand, it can also guide the lifting tube 240, which can effectively prevent the lifting tube 240 from moving relative to the base 212. Rotate.

It should be noted that the connection method between the guide rod cap 252 and the guide rod 251 is not limited in the embodiment of the present application, as long as the guide rod cap 252 and the guide rod 251 can be fixedly connected. For example, the fixed connection between the guide rod cap 252 and the guide rod 251 can be achieved by welding, riveting or threaded connection. The details can be set according to the specific situation, and are not specifically limited in this embodiment.

In addition, in this embodiment, three guide assemblies 250 are spaced apart on the base 212, and each guide assembly 250 Each guide assembly 250 is provided with a first buffer member 261 . Of course, one guide assembly 250 can also be provided with two, three, four or more first buffer members 261 . The first buffer members 261 on each guide assembly 250 are Quantity is not limited. The three guide assemblies 250 are arranged at intervals along the circumferential direction of the base 212, and the corresponding angles between two adjacent guide assemblies 250 are the same, that is, the three guide assemblies 250 are evenly arranged in the circumferential direction of the base 212, that is, That is to say, the first buffer member 261 is evenly arranged in the circumferential direction of the base 212, so that the lifting tube 240 can be evenly stressed, so that the lifting tube 240 will not be deflected during the rising or falling process, thereby reducing the risk of the lifting process. stuck problem. 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.

As shown in FIG. 11 , the number of the first buffer members 261 may also be six, wherein the six first buffer members 261 may be symmetrically distributed around the circumferential center of the lifting tube 240 , so that each first buffer member 261 The force is relatively uniform, and the buffering effect of the first buffer member 261 is relatively balanced. Of course, in some embodiments, the plurality of first buffer members 261 may also be distributed axially symmetrically, or may be distributed asymmetrically. The distribution of the first buffer members 261 is not specifically limited in this embodiment. Of course, it can be understood that the distribution of the guide components 250 can be the same as the distribution of the first buffer members 261 .
