[0087] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as being limited to the examples set forth herein; on the contrary, these embodiments are provided so that the present disclosure will be more comprehensive and complete, and the concepts of the example embodiments are fully conveyed to those skilled in the art.

In other cases, known technical solutions are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0088] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and thus their repeated descriptions will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. The terms "one", "an", "the" and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to indicate an open-ended inclusion and mean that in addition to the listed elements / components / etc., additional elements / components / etc. may exist; the terms "first", "second", etc. are used only as labels and are not quantitative restrictions on their objects.

[0089] The present disclosure provides a lifting mechanism, such as Figure 1-Figure 4 As shown, the lifting mechanism includes: a shell 30, a lifting module 10 and a driving component, the lifting module 10 includes a lifting seat 110 and a microphone 120 and a camera 130 arranged on the lifting seat 110; the driving component is arranged on the shell 30 and connected to the lifting module 10, and the driving component is configured to drive the lifting module 10 to switch between a retracted state and an extended state; wherein, when the lifting module 10 is in the retracted state, the shell 30 blocks the microphone 120 and the camera 130; when the lifting module 10 is in the extended state, the microphone 120 and / or the camera 130 are exposed from the shell 30.

[0090] The lifting mechanism provided by the present invention is that the lifting module 10 can switch between a retracted state and an extended state under the drive of the driving component to realize the lifting function. When the lifting module 10 is in the retracted state, the shell 30 blocks the microphone 120 and the camera 130, and can form a physical shielding for the microphone 120 and the camera 130. Especially in confidential business meetings and government meetings, the presence of the camera 130 and the microphone 120 can avoid the hidden risks of secret recording and eavesdropping, thereby improving the security of the equipment.

[0091] like Figure 2 and Figure 3 As shown, the extended state includes a first extended state and a second extended state. When the lifting module 10 is in the first extended state, the microphone 120 or the camera 130 is exposed from the shell 30; when the lifting module 10 is in the second extended state, the microphone 120 and the camera 130 are both exposed from the shell 30.

[0092] Specifically, Figure 1-Figure 3 As shown, the lifting base 110 of the lifting module 10 is box-shaped, and the lifting base 110 is provided with a sound inlet 1110 for the microphone 120 to input sound, a picture taking hole 1120 for the camera 130 to take pictures, and a light outlet hole 1130 for the flash to emit light. Figure 1 As shown, there are four microphones 120, which are arranged on the same base, and the lifting seat 110 is correspondingly provided with four sound inlet holes 1110. The microphone 120 is arranged in the boxed lifting seat 110, and obtains external sounds through the sound inlet holes 1110. The camera 130 and the flash are arranged on the same base, and the camera 130 is arranged in the boxed lifting seat 110, and takes pictures through the image taking hole 1120, and fills the flash with light through the light outlet hole 1130. Of course, the microphone 120 can also be provided with one, two, three, five or more, and the present disclosure does not limit this.

[0093] like Figure 1 and Figure 2 As shown, the microphone 120 is located on the side where the camera 130 moves toward the extended state. When the lifting module 10 is in the first extended state, the microphone 120 is exposed from the housing 30; when the lifting module 10 is in the second extended state, the microphone 120 and the camera 130 are both exposed from the housing 30. Of course, the camera 130 can also be located on the side where the microphone 120 moves toward the extended state, that is, when the lifting module 10 is in the first extended state, the microphone 120 is exposed from the housing 30; when the lifting module 10 is in the second extended state, the microphone 120 and the camera 130 are both exposed from the housing 30, and the present disclosure does not limit this.

[0094] like Figure 1-Figure 3 As shown, the housing 30 includes a housing cavity with an open end, and the lifting module 10 can extend or retract into the housing cavity through the open end. When the lifting module 10 is in the first extended state, the lifting module 10 and the driving assembly are both located in the housing space of the housing 30. When the camera 130 and the microphone 120 are not in use, the camera 130 and the microphone 120 are hidden, and the camera 130 and the microphone 120 are also protected, thereby improving the reliability of the lifting mechanism.

[0095] For example, Figure 1 and Figure 2As shown, the housing 30 is a rectangular box with an opening for the lifting module 10 to extend or retract into the accommodating cavity. Of course, the housing 30 can also be formed into other shapes, such as cylindrical, polygonal rhombus, elliptical or other irregular shapes, etc., and the present disclosure does not limit this.

[0096] For example, the shell 30 can be formed of a metal material or a non-metal material. The metal material can be, for example, iron, copper, aluminum, zinc, titanium or their alloys, and the non-metal material can be, for example, polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and acrylonitrile-butadiene-styrene copolymer (ABS). Those skilled in the art can also use other materials. All changes involving materials are within the scope of protection of the present disclosure.

[0097] For example, the microphone 120 and the camera 130 may be fixedly connected to the lifting base 110 by bonding, welding, clamping, riveting, etc., and the present disclosure does not limit this.

[0098] like Figure 4 and Figure 5 As shown, the lifting mechanism further includes: a sealing strip 40. The sealing strip 40 is arranged on the housing 30. When the lifting module 10 is in the retracted state, the sealing strip 40 blocks the sound inlet 1110 of the microphone 120. By setting the sealing strip 40, the sealing strip 40 is in contact with the sound inlet 1110, so that the sound inlet 1110 of the microphone 120 can be blocked, further realizing physical blocking of the microphone 120, further avoiding the hidden risks of stealth recording, eavesdropping, etc. caused by the microphone 120, and improving the safety of the device.

[0099] For example, the length and width of the sealing strip 40 can be set according to the sound inlet holes 1110 of the microphone 120 to ensure that each sound inlet hole 1110 can be blocked. All sound inlet holes 1110 can be blocked at the same time by one sealing strip 40, and multiple sound inlet holes 1110 can be blocked separately by multiple sealing strips 40, which is not limited in the present disclosure.

[0100] For example, the material of the sealing strip 40 may be a soft material such as rubber to improve the blocking and noise reduction effect on the microphone 120. In addition, the sealing strip 40 may also be made of a sound-absorbing material, such as sound-absorbing cotton, to further improve the effect of avoiding hidden risks such as secret recording and eavesdropping. Those skilled in the art may also use other materials, and any changes in materials are within the scope of protection of the present disclosure.

[0101] For example, the sealing strip 40 may be fixedly connected to the housing 30 by bonding, welding, clamping, riveting, etc., and the present disclosure does not limit this.

[0102] Next, the driving assembly provided by the present disclosure will be described in detail.

[0103] Embodiment 1

[0104] like Figure 4-Figure 10 As shown, the driving assembly 21 includes: a fixed seat 213 and a lifting motor 211. The fixed seat 213 is fixedly connected to one of the housing 30 and the lifting seat 110; the lifting motor 211 includes a stator and a rotor, the stator is fixedly connected to the other of the housing 30 and the lifting seat 110, and the rotor is connected to the fixed seat 213. The lifting motor 211 can adjust the distance between the fixed seat 213 by rotating the rotor to drive the lifting module 10 to switch between the retracted state and the extended state, that is, to switch between the retracted state, the first extended state and the second extended state.

[0105] For example, Figure 4 As shown, the fixed seat 213 is fixedly connected to the shell 30, and the fixed seat 213 can be fixedly connected to the shell 30 by bonding, welding, clamping, riveting, etc.; the stator of the lifting motor 211 is fixedly connected to the lifting seat 110, and the lifting motor 211 can be fixedly connected to the lifting seat 110 by bonding, welding, clamping, riveting, etc. The lifting motor 211 can be a driving device such as a motor, and the present disclosure does not limit this.

[0106] For example, Figure 4 As shown, the driving assembly 21 further includes: a threaded rod 212. One end of the threaded rod 212 is fixedly connected to the rotor, and the other end is threadedly connected to the fixing seat 213. The lifting motor 211 can drive the threaded rod 212 to rotate through the rotor. Since the threaded rod 212 is threadedly connected to the fixing seat 213, when the threaded rod 212 rotates driven by the rotor, the position of the fixing seat 213 on the threaded rod 212 will change, thereby adjusting the distance between the lifting motor 211 and the fixing seat 213, thereby realizing the switching of the lifting module 10 between the extended state and the retracted state relative to the housing 30.

[0107] For example, Figure 4 As shown, a threaded hole 214 is provided on the fixing seat 213, so as to realize the threaded connection between the threaded rod 212 and the fixing seat 213. In addition, a threaded hole can be directly provided on the fixing seat 213 by tapping, so as to realize the threaded connection between the threaded rod 212 and the fixing seat 213, and the present disclosure does not limit this. It should be noted that by providing the threaded hole 214, the contact area of ​​the threaded connection between the threaded rod 212 and the fixing seat 213 can be increased, thereby improving stability.

[0108] like Figure 4-Figure 12As shown, the driving assembly 21 further includes: a grating shielding plate 215, a grating transmitter 216 and a grating receiver 217. One end of the grating shielding plate 215 is fixedly connected to the lifting seat 110, and the other end is a free end. The grating shielding plate 215 includes a plurality of grating holes arranged at intervals; the grating transmitter 216 is arranged on one side of the grating shielding plate 215; the grating receiver 217 is arranged on the side of the grating shielding plate 215 away from the grating transmitter 216, and the grating receiver 217 can receive the signal emitted by the grating transmitter 216 through the grating hole; when the grating receiver 217 receives the signal emitted by the grating transmitter 216 through the grating hole, the lifting motor 211 stops driving, so that the lifting module 10 is in a retracted state or an extended state.

[0109] For example, Figure 1 , Fig.11 and Fig.12 As shown, the grating shielding plate 215 is fixedly connected to the lifting seat 110, that is, the grating shielding plate 215 moves synchronously with the lifting module 10. Three grating holes are provided on the grating shielding plate 215 for the light emitted by the grating transmitter 216 to pass through. When other parts of the grating shielding plate 215 move between the grating transmitter 216 and the grating receiver 217, the light emitted by the grating transmitter 216 is blocked, and the grating receiver 217 cannot receive the light emitted by the grating transmitter 216; when the grating holes on the grating shielding plate 215 move between the grating transmitter 216 and the grating receiver 217, the light emitted by the grating transmitter 216 can be received by the grating receiver 217. When the grating receiver 217 receives the light, it can be determined that the lifting module 10 has been lifted to the target position, forming a positioning, and the lifting module 10 can stop lifting, thereby improving the positioning accuracy of the lifting module 10. By setting up three grating holes, the lifting module 10 can be positioned in three different positions, which can be a retracted state, a first extended state and a second extended state respectively. If you want to position it in more states, you can set more grating holes. By adjusting the position of the grating holes, you can adjust the lifting position of the lifting module 10 relative to the shell 30.

[0110] like Figure 5 and Figure 6 As shown, the lifting module 10 is in the retracted state, and the grating hole near the top is located between the grating transmitter 216 and the grating receiver 217, so that the lifting module 10 is positioned in the retracted state.

[0111] like Figure 7 and Figure 8 As shown, the lifting module 10 is in the first extended state, and the middle grating hole is located between the grating transmitter 216 and the grating receiver 217, so that the lifting module 10 is positioned in the first extended state.

[0112] like Fig. 9and Fig.10 As shown, the lifting module 10 is in the second extended state, and the grating hole near the bottom is located between the grating transmitter 216 and the grating receiver 217, so that the lifting module 10 is positioned in the second extended state.

[0113] For example, when the grating hole is located between the grating transmitter 216 and the grating receiver 217, the grating receiver 217 can send a positioning information, and the controller is used to control the driving device to operate according to the positioning information to achieve the switching of the lifting module 10 between different positions relative to the shell 30.

[0114] like Figure 4 As shown, the lifting module 10 further includes: a shading plate 140. The shading plate 140 is connected to the lifting seat 110 to form a relatively closed accommodation space with the lifting seat 110, and the microphone 120 and the camera 130 are sealed in the accommodation space to prevent the light generated by the flash from entering the accommodation space of the housing 30, thereby avoiding interference with the grating receiver 217, and improving the reliability of the lifting mechanism. The grating is connected to the shading plate 140 to achieve synchronous movement with the lifting module 10.

[0115] For example, Figure 4 As shown, the size and shape of the shading plate 140 match the size and shape of the open end of the lifting seat 110. The shading plate 140 can be fixedly connected to the lifting seat 110 by bonding, welding, clamping, riveting, etc. The grating baffle plate 215 can be fixedly connected to the shading plate 140 by bonding, welding, clamping, riveting, etc., and the present disclosure does not impose any restrictions on this.

[0116] Embodiment 2

[0117] like Figure 13-Figure 19 As shown, the driving assembly 22 includes: a transmission rack 221 and a driving motor 222, wherein the transmission rack 221 is connected to one of the housing 30 and the lifting seat 110; the driving motor 222 is connected to the other of the housing 30 and the lifting seat 110; the output end of the driving motor 222 is meshed with the transmission rack 221, and the output end of the driving motor 222 can rotate to enable the transmission rack 221 to move relative to the driving motor 222 in the lifting direction of the lifting module 10, so as to drive the lifting module 10 to switch between the retracted state and the extended state. Among them, the driving motor 222 can be a stepping motor, which has high stepping accuracy and does not accumulate stepping errors, so that the lifting module 10 can be driven to the target position more accurately.

[0118] For example, Fig.13As shown, one end of the transmission rack 221 is connected to the lifting seat 110, the driving motor 222 is arranged on the housing 30, and a gear 223 is arranged on the output shaft of the driving motor 222. The other end of the transmission rack 221 is matched and meshed with the gear 223. The driving motor 222 drives the gear 223 to rotate, thereby driving the transmission rack 221 to move up and down, so as to drive the lifting module 10 to move in the manner shown in FIG. Fig.14 , Fig.16 and Fig.18 Switch between the retracted state, the first extended state and the second extended state shown.

[0119] For example, Fig.15 As shown, the transmission rack 221 can be a double-sided rack, one side of which is meshed with the driving gear of the drive motor 222, and the other side is meshed with a fixed driven gear, and the driven gear mainly cooperates with the driving gear to clamp the double-sided rack, so that the double-sided rack is more closely meshed with the driving gear, avoiding separation from the driving gear, and improving the stability and controllability of the up and down movement of the transmission rack 221. In addition, both sides of the double-sided rack can be meshed with the driving gear, and the driving gears on both sides are arranged on the output end of the drive motor 222, which can be respectively on two drive motors 222, or on one drive motor 222 through a gear set transmission, so as to further improve the stability and reliability of driving the transmission rack 221 to move.

[0120] For example, Fig.14 As shown, the driving assembly 22 is provided with two sets of transmission racks 221 and driving motors 222, and the two sets of transmission racks 221 and driving motors 222 are arranged at intervals on both sides of the lifting mechanism to improve the reliability of driving the lifting module 10 to switch between the retracted state and the extended state. Of course, the driving assembly 22 can also be provided with three, four or more sets of transmission racks 221 and driving motors 222, and the structures of each set of transmission racks 221 and driving motors 222 can be completely the same or different, and the present disclosure does not limit this.

[0121] Specifically, the driving assembly 22 further includes: a distance sensor module, the distance sensor module includes a first distance sensor and a second distance sensor, one of the first distance sensor and the second distance sensor is arranged on the lifting module 10, and the other is arranged on the housing 30; the first distance sensor and the second distance sensor can be used to determine the moving distance of the lifting module 10 relative to the housing 30, so as to make the lifting module 10 in a retracted state or an extended state. The first distance sensor and the second distance sensor can be respectively arranged on the lifting module 10 and the housing 30 by bonding, clamping, threaded connection, etc.

[0122] For example, Figure 14-Figure 19As shown, the first distance sensor 224 is provided on the lifting module 10, and the second distance sensor 225 is provided on the housing 30. When the distance between the first distance sensor 224 and the second distance sensor 225 changes, the change in the distance between the two can be determined through the reaction information between the two, thereby determining the position of the lifting module 10 relative to the housing 30, and further determining whether the lifting module 10 is in the retracted state, the first extended state, or the second extended state. When it is desired to locate the retracted state, the first extended state, or the second extended state, the position of the lifting module 10 is determined through the first distance sensor 224 and the second distance sensor 225, thereby controlling the drive motor 222 to work.

[0123] For example, the first distance sensor 224 may be a first Hall sensor, and the second distance sensor 225 may be a second Hall sensor. The first Hall sensor and the second Hall sensor can obtain the distance change information between the two through mutual induction, so as to determine the position of the lifting module 10 relative to the shell 30. Among them, when the lifting module 10 is in the retracted state, the positions of the first Hall sensor and the second Hall sensor are relatively overlapped, that is, in the lifting direction of the lifting module 10, the heights of the first Hall sensor and the second Hall sensor are consistent, and the distance between the two is zero, which is convenient for judging that the lifting module 10 is in the retracted state. Of course, when the lifting module 10 is in the retracted state, the positions of the first Hall sensor and the second Hall sensor can also be relatively staggered, and the present disclosure does not limit this.

[0124] Of course, the distance sensor module in this embodiment can also be replaced by the grating, grating transmitter 216 and grating receiver 217 in the first embodiment to determine whether the lifting module 10 is in the retracted state, the first extended state or the second extended state.

[0125] For example, Fig.13 As shown, the lifting module 10 further includes a shading plate 140, which is connected to the lifting seat 110 to form a relatively closed accommodation space with the lifting seat 110, and seals the microphone 120 and the camera 130 in the accommodation space. The first distance sensor 224 is disposed on a side of the shading plate 140 close to the second distance sensor 225, and the second distance sensor 225 is disposed on the side wall of the housing 30; of course, the second distance sensor 225 can also be disposed on the shading plate 140, and the first distance sensor 224 can be disposed on the side wall of the housing 30, and the present disclosure does not limit this.

[0128] For example, Fig.21 and Fig. 22 As shown, one end of the positioning pin 231 is connected to the lifting seat 110, and the conveyor belt module is arranged on the housing 30. The conveyor belt module includes a group of rollers (a first roller 232 and a second roller 233) and a conveyor belt 234 arranged on the rollers. Driven by the rollers, the conveyor belt 234 can roll in the height direction. The other end of the positioning pin 231 is connected to the conveyor belt 234 of the conveyor belt module. Through the rolling of the conveyor belt 234, the positioning pin 231 can move relative to the conveyor belt module in the lifting direction of the lifting module 10 to drive the lifting module 10 to switch between the retracted state and the extended state. Among them, one of the first roller 232 and the second roller 233 can be a driving wheel, and the other can be a driven wheel; of course, both the first roller 232 and the second roller 233 can be driving wheels, and drive the conveyor belt 234 to roll at the same time.

[0129] For example, Fig. 22 As shown, one end of the locating pin 231 connected to the conveyor belt module is provided with a hook 238, and a snap-in hole 235 is provided on the conveyor belt 234. The hook 238 extends into the snap-in hole 235 to form a snap connection between the locating pin 231 and the conveyor belt 234; of course, one end of the locating pin 231 and the conveyor belt 234 can also be connected together by bonding, riveting, etc., and the present disclosure does not limit this.

The reflector 236 is disposed on one of the housing 30 and the lifting seat 110, and the laser distance measuring transmitting end 237 is disposed on the other of the housing 30 and the lifting seat 110. The laser distance measuring transmitting end 237 can determine the distance between the reflector 236 and the lifting seat 110, thereby determining the distance of the lifting module 10 relative to the housing 30, and further determining whether the lifting module 10 is in the retracted state or the extended state.

[0131] For example, Fig.24As shown, the reflector 236 is disposed on the lifting seat 110, and the laser ranging transmitting end 237 is disposed on the housing 30, and the reflector 236 and the laser ranging transmitting end 237 are disposed opposite to each other. When the lifting module 10 moves up and down, the reflector 236 is driven to move synchronously, and the laser emitted by the laser ranging transmitting end 237 is reflected by the reflector 236 and then returns to the laser ranging transmitting end 237. The laser ranging transmitting end can determine the relative distance to the reflector 236 by determining the time when the emitted laser is reflected back, thereby determining the moving position of the lifting module 10, and further determining whether the lifting module 10 is in the retracted state, the first extended state, or the second extended state.

[0132] For example, Fig. 20 As shown, the lifting module 10 further includes a shading plate 140 , which is connected to the lifting base 110 to form a relatively closed accommodation space with the lifting base 110 , and seals the microphone 120 and the camera 130 in the accommodation space.

One of the first magnet 2411 and the second magnet 2422 is disposed at one end of the first limit member 2411 close to the second limit member 2412, and the other is disposed at one end of the first limit member 2411 close to the second limit member 2412. It is arranged at one end of the second limit member 2412 away from the first limit member 2411, and the polarity of the first magnet 2421 is opposite to that of the second magnet 241; the second magnet module includes electromagnets respectively arranged on the shell 30 and the lifting seat 110, and the lifting module 10 is driven to be in the extended state by controlling the electromagnets arranged on the shell 30 and the lifting seat 110 to repel each other; the lifting module 10 is driven to be in the retracted state by controlling the electromagnets arranged on the shell 30 and the lifting seat 110 to attract each other or have no interaction force.

[0137] For example, the first magnet 2421 and the second magnet 2422 are permanent magnets, and the polarities of the first magnet 2421 and the second magnet 2422 are opposite, and a continuous attraction can be provided between the first magnet 2421 and the second magnet 2422 to keep the lifting module 10 in the position as shown in FIG. Fig.28 and Fig.29 The retracted state shown, that is, when the lifting module 10 is not in use, does not require power control, which improves the stability in the retracted state. Of course, the first magnet 2421 and the second magnet 2422 can also be electromagnets, and the two can be attracted, repelled or have no interaction force by powering on or off.

[0138] For example, Fig.28 , Fig.30 and Fig.32 As shown, the second magnet module includes: a first sub-magnet module and a second sub-magnet module, the first sub-magnet module includes a first electromagnet 2431 and a second electromagnet 2432, one of the first electromagnet 2431 and the second electromagnet 2432 is arranged on the lifting seat 110, and the other is arranged on the shell 30; the second sub-magnet module includes a third electromagnet 2441 and a fourth electromagnet 2442, one of the third electromagnet 2441 and the fourth electromagnet 2442 is arranged on the lifting seat 110, and the other is arranged on the shell 30; wherein, by making one group of electromagnets in the first sub-magnet module and the second sub-magnet module repel each other, and the other group of electromagnets repel each other without interaction force, so that the lifting module 10 is in the following Fig.30 and Fig.31 by making the first sub-magnet module and the second sub-magnet module in the electromagnets are repelled, so that the lifting module 10 is in such a Fig.32 and Fig.33 The second extended state is shown. Wherein, each magnet in the second magnet module can be an electromagnet.

[0139] For example, Fig.30 As shown, the first sub-magnet module also includes a support column 2433, and the second electromagnet 2432 is arranged on the support column 2433 to reduce the distance between the first electromagnet 2431 and the second electromagnet 2432, so that the first electromagnet 2431 and the second electromagnet 2432 can provide a greater repulsive force to drive the lifting module to rise. Of course, the second sub-magnet module can also be provided with a support column for setting the fourth electromagnet 2442, and the present disclosure does not limit this.

The two groups of first sub-magnet modules and the two groups of second sub-magnet modules are symmetrically distributed on both sides of the first magnet module to improve the stability of driving the lifting module 10.

When the lifting module 10 switches between the retracted state, the first extended state, and the second extended state, the second limiter 2412 is inserted into the first limiter 2411 to limit the moving direction of the lifting module 10, thereby improving the lifting stability of the lifting module 10. Of course, the first limiter 2411 and the second limiter 2412 are also sliding rails connected in a sliding manner, thereby limiting the moving direction of the lifting module 10. The present disclosure does not limit this, and any technical solution that can achieve the same technical effect belongs to the protection scope of the present disclosure.
