Description

Cell-phone safety lift camera

Technical Field

The invention belongs to the field of mobile phones, and particularly relates to a mobile phone safety lifting camera.

Background

Currently, along with the evolution of the aesthetic value and design of the mobile phone, a mobile phone capable of lifting a camera is already available in the market; the camera of the mobile phone is normally retracted in the body, and is extended out of the screen to take a picture when in use; in the prior art, the lifting mode of the camera usually adopts a screw and nut transmission mode to drive the camera to stretch.

When the existing mobile phone with the function of lifting the camera is used for taking a picture, if the mobile phone is dropped carelessly, the camera which extends out of the inside of the mobile phone body is easy to be impacted and damaged. And for solving the problem of camera impact damage among the prior art, mainly adopt three kinds of schemes:

firstly, the falling action of the mobile phone is sensed by the sensor in the mobile phone to control the motor to reversely rotate the nut, so that the camera is retracted into the mobile phone body in the falling process of the mobile phone. The adoption of the mode has more defects, for example, the sensor controls the motor to rotate reversely through the sensing signal, so that the camera cannot be completely retracted before the mobile phone falls off the ground, and the camera is damaged by impact; for another example, once the sensor fails to sense the falling action of the mobile phone, the unretracted camera head may be damaged by impact.

The second is that the camera is arranged in the fan-shaped structure which can swing in the machine body and outside the machine body, the fan-shaped structure is swung out of the machine body when a user takes a picture, and when the mobile phone falls and the fan-shaped structure is impacted, the fan-shaped structure can be pressed back into the machine body by impact force. However, the mobile phone adopting the structure scheme has a large installation space, and the anti-collision effect cannot completely protect the camera, so that only a small number of mobile phones in the market adopt the scheme.

The third kind, through the powerful impact force that cushions the camera with the camera ejection organism external boosting spring, but the reaction force that the camera was provided to the boosting spring, the powerful impact force that combines the camera to receive again for the camera is damaged by the centre gripping of reaction force and impact force more easily.

Therefore, in order to solve the problem of the collision damage of the camera, a new device for protecting the lifting camera needs to be designed.

In addition, when the camera extends out of the body and is used for self-shooting, the angle of a user holding the mobile phone generally cannot enable the screen of the mobile phone to be basically parallel to the face of the user, and the user can generally cut the face at a certain angle to use the mobile phone more comfortably; however, the camera of the mobile phone inclined to the face cannot be substantially parallel to the face after extending out of the body, so that the user needs to adjust the mobile phone to a direction substantially parallel to the face to perform a better self-photographing. In order to enable a camera extending out of the machine body to be basically parallel to the face when a mobile phone of a user is inclined to the face, a novel device for adjusting the angle of the lifting camera needs to be designed.

The invention designs a safe lifting camera of a mobile phone to solve the problems.

Because the compression amount generated by the boosting spring when the camera is impacted is small, and the boosting spring in the traditional lifting camera does not have the maximum compression amount to buffer the impact of the camera, when the boosting spring is used for buffering the impact of the camera, the reaction force provided by the boosting spring to the camera is small, and the possibility that the camera is clamped by the small reaction force and the impact force and damaged is greatly reduced by combining the external impact force received by the camera. Simultaneously, through the action of drawing the camera back in the organism in the twinkling of an eye again, can weaken greatly to the impact that the camera received more, reach the purpose of protection camera.

The A cylinder 7 can provide a containing space for resetting the tension spring 27 in the invention. The arc piece 26 with elasticity in the present invention can be made of rubber material or elastic plastic.

In the invention, the elastic coefficient of the boosting spring 25 is larger than that of the compression spring 29, so that when the boosting spring 25 is slightly compressed, the boosting spring 25 can push the sliding disk 28 to continuously compress the compression spring 29.

The base 1 of the present invention may be an inner wall of the machine body, or may be a mounting base mounted in the machine body.

The specific working process is as follows: the camera 20 is in an initial state when not extending out of the machine body for self-timer shooting, as shown in fig. 1 and 5, the bottom of the cylinder a 7 in the initial state is positioned on the support a 15, the lower surface of the sliding plate 12 is attached to the upper surface of the fixed plate 13, and the nut 5 is positioned at the lower end of the screw rod 4; as shown in fig. 5 and 7, the tension spring 27 is in a stretched state, the end of the arc surface 37 of the swing plate 33 completely abuts against the end of the arc surface 37 of the corresponding accommodating groove 34, and the inclined upper plate surface of the swing plate 33 abuts against the end surface of the corresponding limit plate 36, so that the limit plate 36 limits the upward swing of the swing plate 33, thereby maintaining the tension spring 27 in the stretched state by limiting the swing plate 33 in the corresponding accommodating groove 34 and maintaining the relative rest of the a-cylinder 7 and the bottom of the sleeve 9; as shown in fig. 5, 6 and 8, the upper disk surface of the sliding disk 28 is in contact with the inward protruding end 35 provided at the tip end of the B cylinder 10, and the compression spring 29 is set in a preloaded state.

When the camera 20 needs to be extended out of the machine body for self-shooting, the control system controls the motor 2 to rotate positively, the motor 2 drives the screw rod 4 to rotate positively through the speed reducer 3, and the screw rod 4 rotating positively enables the nut 5 to drive the A cylinder 7 to move upwards through the Z-shaped plate 6 through the thread matching with the nut 5. Because the cambered surface 37 end of the swinging plate 33 is completely attached to the cambered surface 37 end of the corresponding accommodating groove 34, the limiting plate 36 limits the swinging of the swinging plate 33, so that the relative rest of the A cylinder 7 and the bottom of the sleeve 9 can be maintained, and the A cylinder 7 can drive the sleeve 9 to move upwards through the swinging plate 33 and the limiting plate 36; the upward moving sleeve 9 pushes the A sliding block 14 to move upwards on the vertical section of the A square rod 8 through the B cylinder 10, the pressure spring 29, the sliding disc 28 and the boosting spring 25, the sliding plate 12 synchronously moving along with the A sliding block 14 is gradually far away from the fixed plate 13, and the corresponding arc piece 26 in the A sliding block 14 is in sliding fit with the A square rod 8; the A slide block 14 drives the camera 20 to extend out of the machine body through the base 19. When the A sliding block 14 is connected with the connecting part of the vertical section and the bending section 24 of the A square rod 8, the control system controls the motor 2 to stop rotating, the nut 5 does not reach the top end of the screw rod 4 at the moment, and the A sliding block 14 stops at the connecting part of the vertical section and the bending section 24 of the A square rod 8; the camera 20 in this state is parallel to the body, and the camera 20 can perform self-timer shooting.

When the face of the user inclines to the mobile phone screen and the user does not want to adjust the comfortable angle between the mobile phone screen and the face, the user can click an image button of the self-timer camera 20 angle adjusting function on the mobile phone screen, so that the control system controls the motor 2 to continuously rotate forwards; after the motor 2 rotates forwards through a series of transmission, the upward moving sleeve 9 pushes the a sliding block 14 to move upwards continuously on the a square rod 8 through the B cylinder 10, the pressure spring 29, the sliding disc 28 and the boosting spring 25, and when the a sliding block 14 moves in an arc shape along the bending section 24 on the a square rod 8, the arc piece 26 in the a sliding block 14 automatically deforms to enable the a sliding block 14 to slide smoothly on the bending section 24 on the a square rod 8; the A slider 14 that the arc moved up drives camera 20 through base 19 and is the arc motion outside the organism for camera 20 is no longer parallel with the organism, and the camera 20 of doing the arc motion like this can make camera 20 be parallel basically with user's face when moving certain angle, thereby guarantees to carry out good auto heterodyne by camera 20. Of course, when the angle of the camera 20 inclined to the machine body reaches the set maximum angle, the control system does not control the motor 2 to continue to rotate forward any more, and at this time, the nut 5 is close to the top end of the screw rod 4, so as to ensure that the camera 20 inclined to the maximum angle of the machine body can be smoothly retracted into the machine body.

The process of retracting the camera 20 extending out of the body into the body: the control system controls the motor 2 to rotate reversely, the motor 2 drives the screw rod 4 to rotate reversely through the speed reducer 3, and the nut 5 drives the A cylinder 7 to move downwards through the Z-shaped plate 6 by the reversely rotating screw rod 4 through the thread matching with the nut 5. At this time, because the tension spring 27 is in a stretching state, the cambered surface 37 end of the swing plate 33 in the sleeve 9 can be maintained to be tightly attached to the cambered surface 37 end of the corresponding accommodating groove 34, and the limit plate 36 is combined to limit the upward swing of the swing plate 33, so that the relative rest of the A cylinder 7 and the bottom of the sleeve 9 can still be maintained, and the A cylinder 7 can enable the sleeve 9 to synchronously move downwards along with the A cylinder 7 under the action of large stretching force of the tension spring 27; the downward moving sleeve 9 drives the sliding disc 28 to move downward through the inward convex end 35 of the B cylinder 10, the sliding disc 28 pulls the A sliding block 14 to move downward on the bending section 24 and the vertical section of the A square rod 8 through the boosting spring 25, the sliding plate 12 synchronously moving along with the A sliding block 14 is gradually close to the fixed plate 13, and the corresponding arc piece 26 in the A sliding block 14 is in sliding fit with the A square rod 8 through automatic deformation; the A slide block 14 drives the camera 20 to gradually retract into the machine body through the base 19. When the nut 5 moves downwards to the initial position, the motor 2 stops rotating reversely, the bottom of the A cylinder 7 is positioned on the A support 15, and the lower surface of the sliding plate 12 is attached to the upper surface of the fixed plate 13.

In the self-timer process with the camera 20, the mobile phone is inadvertently dropped. If the sensor controls the motor 2 to rotate reversely through the sensing signal, the camera 20 cannot be completely retracted before the mobile phone falls on the ground, or the sensor fails to sense the falling action of the mobile phone, so that the camera 20 outside the mobile phone is impacted and retracts into the mobile phone instantly. Firstly, when the camera 20 is impacted, the camera 20 drives the a slide block 14 to retract instantly through the base 19, the boosting spring 25 in the invention can instantly compress the impact of the camera 20 to buffer, but after the boosting spring 25 is compressed a little instantly, the elastic force of the boosting spring 25 is larger than that of the compression spring 29, the boosting spring 25 pushes the sliding disk 28 to move downwards instantly towards the bottom of the B cylinder 10, and the compression spring 29 is continuously compressed instantly. The sliding disk 28 drives the rack 30 to move downwards instantly to enable the rack 30 to drive the gear 32 to rotate a certain angle instantly, the gear 32 drives the swing plate 33 to swing towards the installation groove 31 instantly, then the arc surface 37 on the swing plate 33 is not attached to the arc surface 37 in the accommodating groove 34 instantly, so that the relatively static state between the A cylinder 7 and the sleeve 9 is removed instantly, the tension spring 27 pulls the B cylinder 10 and the sleeve 9 to move downwards instantly under the large reset force of the tension spring 27, the B cylinder 10 pulls the A slide block 14 to move downwards instantly through the pressure spring 29, the sliding disk 28 and the boosting spring 25, and the A slide block 14 pulls the camera 20 into the machine body instantly through the base 19, so that the possibility that the camera 20 is damaged by impact is greatly reduced.

When the sliding plate 12 of the B-tube 10 which is momentarily moved down is engaged with the fixed plate 13, the B-tube 10 will not move down any more. If the A slide 14 moves downwards from the top of the bending section 24 on the A square rod 8 instantly, when the slide plate 12 on the B cylinder 10 moving downwards instantly is jointed with the fixed plate 13, the distance between the B cylinder 10 and the A cylinder 7 is minimum, and the tension spring 27 returns to the natural state. If the a slide 14 moves down instantaneously from the top of the vertical section on the a square rod 8, when the slide plate 12 on the B cylinder 10 moving down instantaneously is attached to the fixed plate 13, the distance between the B cylinder 10 and the a cylinder 7 is not minimum, and the tension spring 27 is still in a certain tension state. After the camera 20 is retracted into the body, under the reset action of the pressure spring 29, the sliding disk 28 is attached to the inward convex end 35 of the B cylinder 10 again, the sliding disk 28 drives the rack 30 to move upward for reset, and the upward rack 30 drives the swing plate 33 to swing out of the mounting groove 31 again through the gear 32.

When the camera 20 is retracted into the machine body and the barrel A7 and the sleeve 9 need to be restored to the original state again, the motor 2 is controlled to rotate reversely, the motor 2 drives the screw rod 4 to rotate reversely through the speed reducer 3, and the nut 5 drives the barrel A7 to move downwards through the Z-shaped plate 6 by the aid of the reverse screw rod 4 in threaded fit with the nut 5. When the lower surface of the A cylinder 7 which moves downwards extrudes the swing plate 33 which swings out of the installation groove 31, the swing plate 33 is extruded into the installation groove 31 again, the swing plate 33 drives the rack 30 to move downwards through the gear 32, and the rack 30 drives the sliding disk 28 to move downwards to further compress the compression spring 29. Then, the cylinder A7 moving downwards continuously enables one end of the upper cambered surface 37 of the swinging plate 33 to be in sliding fit with the inner wall of the circular hole arranged at the cylinder bottom of the cylinder A7. When the bottom of the A cylinder 7 is attached to the A support 15, the motor 2 is controlled to stop; at this moment, the swing plate 33 is opposite to the corresponding accommodating groove 34, the circle center of the arc surface 37 in the corresponding accommodating groove 34 is located on the central axis of the gear 32, the sliding disc 28 moves upwards to reset under the resetting action of the pressure spring 29, the sliding disc 28 drives the swing plate 33 to swing out of the mounting groove 31 again through the rack 30 and the gear 32, the arc surface 37 on the swing plate 33 after swinging out is attached to the arc surface 37 on the corresponding accommodating groove 34 again, and the inclined upper plate surface of the swing plate 33 is attached to the end surface of the corresponding limiting plate 36.

In the invention, the sliding action of the B slide block 18 on the B square rod 17 is identical to the sliding action of the A slide block 14 on the A square rod 8, and the sliding action of the B slide block 18 can refer to the sliding action of the A slide block 14.

The A cylinder 7 and the sleeve 9 are kept relatively still in a mode that the upper cambered surface 37 of the swinging plate 33 is attached to the upper cambered surface 37 of the accommodating groove 34, the tension spring 27 is stretched, and the swinging plate 33 is limited by the limit plate 36 to swing upwards; the last cambered surface 37 of pendulum plate 33 and the last cambered surface 37 of holding tank 34 the mode carries out final spacing, and the benefit of adopting this kind of method is: the stress is good, and the unlocking is easy. In this way, the locking or unlocking can be realized by referring to the design principle of the trigger structure of the pistol.

While the present invention has been described in conjunction with the above embodiments, the present invention is not limited to the above embodiments but is limited only by the appended claims, and those skilled in the art can easily make modifications and variations thereto without departing from the true spirit and scope of the present invention.
