DETAILED DESCRIPTION
[0062] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0063] See also Figures 1 to 3 As shown, this embodiment provides a lifting device for a camera, which utilizes a ratchet mechanism 18 to separate the driving member 19 and the transmission mechanism 15, thereby avoiding a rigid connection between the driving member 19 and the transmission mechanism 15, so that the camera 10 can withstand greater external impacts, extending the service life of the lifting device, and providing a basis for quickly closing the camera 10.
[0064] Specifically, the lifting device includes a lifting rail 11 , and the lifting rail 11 is slidably connected with a camera 10 .
[0065] The driving member 19 is connected to the ratchet mechanism 18, the ratchet mechanism 18 is connected to the transmission mechanism 15, and the transmission mechanism 15 is connected to the camera 10 to drive the camera 10 to descend. Optionally, the driving member 19 is a motor.
[0066] The ratchet mechanism 18 includes a pawl 181 and a ratchet wheel 182 . The ratchet wheel 182 is connected to the pawl 181 , and the driving member 19 is connected to the pawl 181 .
[0067] The transmission mechanism 15 includes a driving wheel 151, which is sleeved and mounted on the ratchet 182 to be fixed. The driving wheel 151 is meshedly connected with a first transmission wheel 152, and the first transmission wheel 152 is provided with a first meshing tooth 1521 and a second meshing tooth 1522, and the first meshing tooth 1521 meshes with the driving wheel 151. The second meshing tooth 1522 is meshedly connected with a second transmission wheel 153, and the second transmission wheel 153 meshes with the second meshing tooth 1522. The second transmission wheel 153 is also meshedly connected with a rack 154, and the rack 154 is connected to the camera 10.
[0068] Therefore, the working principle of the camera lifting device provided in this embodiment is as follows:
[0069] When the camera 10 is closed, the driving member 19 drives the pawl 181 to rotate counterclockwise, and the ratchet 182 follows the rotation; the driving wheel 151 rotates counterclockwise and drives the first transmission wheel 152 to rotate clockwise through the first meshing tooth 1521, and then drives the second transmission wheel 153 to rotate counterclockwise through the second meshing tooth 1522, thereby driving the rack 154 to move downward, thereby realizing the descent of the camera 10.
[0070] Since the ratchet mechanism 18 is a unidirectional motion mechanism, when the camera 10 descends, even if the camera 10 is subjected to external impact (such as pressing the camera 10), it will not cause damage to the transmission mechanism 15, thereby extending the service life of the lifting device and providing a basis for quickly closing the camera 10.
[0071] See also Figures 4 to 8 As shown, in another embodiment of the present application, a lifting device for a camera is provided, which can realize rapid lifting and lowering of the camera 10 through an ejection assembly 30, and the lifting device is not easily damaged.
[0072] The ejection assembly 30 includes a first elastic element 12, a lock hook 13 and a lifting and unlocking module 20. Specifically, the first elastic element 12 is connected to one side of the bottom of the camera 10, and the first elastic element 12 is arranged along the sliding direction of the camera 10, and the lock hook 13 is provided with a stopper 131 for compressing the first elastic element 12.
[0073] When the camera 10 is retracted in the electronic device, the first elastic element 12 is compressed by the block 131 and the movement of the lock hook 13 needs to be restricted; when the camera 10 needs to be opened, the movement of the lock hook 13 needs to be unlocked so that the lock hook 13 can move upward, and under the elastic force of the first elastic element 12, the camera 10 is quickly popped out.
[0074] The lifting and unlocking module 20 is used to limit and release the movement of the locking hook 13. The lifting and unlocking module 20 includes a fixed bottom plate 21 and a cover plate 22. An unlocking switch 23 is rotatably connected to the fixed bottom plate 21. The two ends of the locking hook 13 are respectively connected to the bottom of the camera 10 and the left side of the unlocking switch 23. A toggle switch 25 is also provided on the fixed bottom plate 21. The toggle switch 25 is rotatably connected to the fixed bottom plate 21 and is used to limit and release the rotation of the unlocking switch 23.
[0075] The working principle of the camera lifting device provided in this embodiment is as follows:
[0076] When closing the camera 10, the camera 10 can be pressed manually, and the camera 10 descends along the lifting guide rail 11. At this time, the lock hook 13 descends and compresses the first elastic element 12 through the stopper 131, and the unlocking switch 23 rotates and rotates until it is restricted by the toggle switch 25. Of course, the camera 10 can also be electrically closed by the driving member 19, that is, the driving member 19 drives the transmission mechanism 15 through the ratchet mechanism 18 to drive the camera 10 to descend.
[0077] When the camera 10 is turned on, the rotation restriction 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, and the lock hook 13 is quickly ejected and raised under the action of the elastic force. At the same time, the unlocking switch 23 rotates, thereby driving the camera 10 to quickly rise along the lifting guide rail 11. It should be noted that in order to prevent the ratchet mechanism 18 from affecting the opening of the camera 10, the ratchet 181 can be driven to rotate clockwise by the driving member 19 while the camera 10 is turned on, so that the camera 10 can be ejected smoothly.
[0078] The lifting device for a camera provided in this embodiment can quickly pop out the camera 10 through the first elastic element 12, thereby reducing the user's waiting time and improving the user experience. In addition, the lifting device can withstand large external impacts and is not easily damaged.
[0079] In order to smoothly reset the unlocking switch 23, the lifting device of the camera further includes a second elastic element 24, the fixed end of the second elastic element 24 is connected to the fixed bottom plate 21, and the free end is connected to the right end of the unlocking switch 23. Therefore, when the camera 10 is turned on, the toggle switch 25 is operated, and the unlocking switch 23 rotates rapidly clockwise under the action of the second elastic element 24.
[0080] The lifting device of the camera also includes a guide shaft 16, and the first elastic element 12 and the stopper 131 are respectively mounted on the guide shaft 16 to guide the compression and release of the first elastic element 12 and the sliding of the stopper 131, thereby improving the stability of the ejection of the camera 10.
[0081] Since the first elastic element 12 is relatively long, the deformation of various parts of the element is likely to be inconsistent when it is compressed. Therefore, in order to further improve the stability of the ejection and compression of the first elastic element 12, the lock hook 13 is provided with at least two blocks 131, and the at least two blocks 131 are spaced apart and sleeved on the first elastic element 12.
[0082] For electronic devices, when the camera 10 is raised or lowered, that is, when the camera 10 is turned on or off, corresponding feedback is required to sense the position of the camera 10. Therefore, a first position sensor 17 for sensing the position of the stopper is provided on one side of the first elastic element 12, and a second position sensor 29 for sensing the position of the unlocking switch is provided on the fixed bottom plate 21.
[0083] In another embodiment of the present application, the bottom of the lock hook 13 is further provided with a connection hole 132, and the left end of the unlocking switch 23 is provided with a U-shaped groove 231, and the lock hook 13 and the unlocking switch 23 are connected by a side wall of the connection hole 132 being inserted into the U-shaped groove 231. Therefore, during the lifting and lowering process of the camera 10, the lock hook 13 pushes the side wall of the U-shaped groove 231 through the side wall of the connection hole 132, thereby driving the unlocking switch 23 to rotate clockwise and counterclockwise.
[0084] In another embodiment of the present application, the lifting device of the camera further includes:
[0085] The electromagnet 26 is connected to a pull rod 27 through electromagnetic magnetic force, and the pull rod 27 is connected to the toggle switch 25;
[0086] The third elastic element 28 is sleeved on the pull rod 27 .
[0087] Therefore, when the camera 10 needs to be turned on, the control signal can be sent out by operating the touch command or button of the electronic device to energize the electromagnet 26. After the electromagnet 26 is energized, the pull rod 27 is attracted by the electromagnetic magnetic force, so that the pull rod 27 moves to the left, and the toggle switch 25 is pulled by the pull rod 27 to unlock 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.
[0088] In order to facilitate limiting and releasing the limit of the rotation of the unlocking switch 23 , a stepped groove 251 for supporting the unlocking switch 23 is provided at one end of the toggle switch 25 away from the pull rod 27 .
[0089] In the above embodiment, the first elastic element 12 , the second elastic element 24 and the third elastic element 28 are all springs.
[0090] In another embodiment of the present application, in order to make the lifting of the camera 10 more stable and prevent the camera 10 from shaking, the lifting device further includes an X-link assembly 14, and the camera 10 is connected to the X-link assembly 14. Therefore, when the camera 10 is lifted or lowered, the X-link assembly 14 is unfolded and folded accordingly, so that the camera 10 is lifted or lowered stably.
[0091] Specifically, the X-link assembly 14 includes an X-link, a fixed seat 142 and a lifting seat 141 connected to the camera 10. The fixed seat 142 is stationary relative to the lifting rail 11, and the lifting seat 141 can slide on the lifting rail 11 following the camera 10.
[0092] The X-link includes a first connecting rod 145 and a second connecting rod 146 arranged crosswise, one end of the first connecting rod 145 is slidably connected to the lifting seat 141 through the first slider 143, and the other end is hinged to the fixed seat 142 for fixation. One end of the second connecting rod 146 is slidably connected to the fixed seat 142 through the second slider 144, and the other end is hinged to the lifting seat 141 for fixation.
[0093] Therefore, the working principle of the X-link assembly 14 is:
[0094] When the lifting seat 141 is lifted or lowered, the fixed seat 142 remains in the same position, thereby changing the distance between the lifting seat 141 and the fixed seat 142. At this time, one end of the first connecting rod 145 slides horizontally on the lifting seat 141 through the first slider 143, and one end of the second connecting rod 146 slides horizontally on the fixed seat 142 through the second slider 144. Practice has proved that the use of the X-link assembly 14 can effectively improve the lifting stability of the camera 10 and prevent the camera 10 from shaking.
[0095] The X-link is ultra-thin, with an overall thickness of only 7.5 mm, and has the advantages of occupying a small space and being light in weight.
[0096] The lifting seat 141 is provided with a first sliding groove 1411 for sliding connection with the first sliding block 143. The lifting seat 141 is formed as a sheet metal part in one piece, which can achieve an ultra-thin and low-cost effect.
[0097] Similarly, the fixing seat 142 is provided with a second sliding groove 1421 for sliding connection of the second slider 144. The fixing seat 142 is an integrally formed sheet metal part, which can achieve an ultra-thin and low-cost effect.
[0098] Since the first connecting rod 145 is a metal part, in order to avoid direct friction between the metal part and the first slide groove 1411 and wear, the first slider 143 includes a first sheet metal part 1431 and a first plastic part 1432. The first plastic part 1432 is provided with a first wrapping groove 14321, and the two sides of the first sheet metal part 1431 are wrapped by the two first wrapping grooves 14321, and the first plastic part 1432 is set to be slidably connected with the first slide groove 1411. 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 slide groove 1432, so that the first slider 143 of this structure has the advantage of low cost.
[0099] Similarly, in order to avoid wear caused by direct friction between the metal part and the second slide groove 1421, the structure of the second slider 144 is the same as that of the first slider 143, and also includes a sheet metal part and a plastic part. The second slider 144 is also slidably connected to the second slide groove 1421 through a plastic part, so that the second slider 144 of this structure has the advantage of low cost.
[0100] As an optional mode of this embodiment, a first limiter for limiting the maximum sliding stroke of the first slider 143 is provided on the lifting seat 141. There are two first limiters, which are respectively located on both sides of the first slider 143. Similarly, a second limiter for limiting the maximum sliding stroke of the second slider 144 is provided on the fixing seat 142. There are two second limiters, which are respectively located on both sides of the second slider 144.
[0101] In another embodiment of the present application, an electronic device is provided, including a lifting device for a camera as provided in any of the above embodiments. The electronic device may be a mobile terminal such as a mobile phone with a camera 10. The lifting device can quickly pop up the camera 10, thereby reducing the user waiting time and improving the user experience. The lifting device can withstand a large external impact and is not easily damaged. When the camera 10 is quickly lifted or lowered, the X-link assembly 14 can also be used to effectively improve the lifting stability of the camera 10 and prevent the camera 10 from shaking.
[0102] In another embodiment of the present application, a camera lifting method is provided, which can be applied to the above lifting device and electronic device, and specifically includes the following steps:
[0103] Acquire a control signal of the camera 10 in real time; optionally, the control signal comes from a touch command of the electronic device, a shortcut key button or a device program command;
[0104] When the control signal is to turn on the camera 10, the elastic component 30 is released to eject the camera 10 upward; specifically, the electromagnet 26 is energized, and the pull rod 27 is controlled by magnetic force to apply a pulling force to the toggle switch 25, and the toggle switch 25 rotates to release the restriction on the unlocking switch 23. At this time, the first elastic element 12 ejects the camera 10, and the camera 10 slides upward on the lifting guide rail 11;
[0105] If the control signal is to turn off the camera 10, the ratchet mechanism 18 is driven, and the camera 10 is driven to descend through the transmission mechanism 15 connected to the ratchet mechanism 18; specifically, the driving member 19 drives the ratchet mechanism 18, thereby making the transmission mechanism 15 work, and driving the rack 154 to descend, thereby driving the camera 10 to descend.
[0106] When the camera 10 is lifted and slid on the lifting guide rail 11 , the X-link assembly 14 is used to achieve smooth lifting.
[0107] The camera lifting device, lifting method and electronic equipment provided by the above embodiments can realize the smooth and rapid lifting and lowering of the camera 10, and the lifting device is not easily damaged.
[0108] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents.
