In the embodiment of the present application, the apparatus main body includes an apparatus housing 100, and the apparatus housing 100 provides a mounting base for a part of the functional components of the electronic apparatus. In the present embodiment, the device housing 100 has an inner cavity and a first opening communicating with the inner cavity.

The device housing 100 has a bezel and the components of the device housing 100 of different configurations that form the bezel are different. For example, the device case 100 may include a front case, a rear cover, and a middle frame disposed therebetween. The rim may be formed on the middle frame. In which case the border acts as part of the middle frame. For another example, the device housing 100 includes a front cover and a back cover, and the bezel may be formed on the back cover or the front cover. In general, the frame defines a first opening, which is communicated with the inner cavity, and the first opening is used for the functional module 200 to pass through and enter the device housing 100. Of course, the function module 200 can enter and exit the device housing 100 through other passages, and is not limited to the first opening formed on the frame.

The function module 200 is movably disposed in the inner cavity, such that the function module 200 can enter and exit the equipment housing 100 through the first opening.

The driving mechanism 300 is partially disposed in the device housing 100, the driving mechanism 300 includes an operation knob 310, a worm 320, a transmission wheel 330, a rocker assembly 340 and a rack 350, the operation knob 310 is disposed in the device housing 100, and the operation knob 310 is rotatable relative to the device housing 100. The device housing 100 also defines a second opening. A portion of the operation knob 310 is exposed to the outer surface of the device housing 100 through the second opening, so as to facilitate the operation of the user, and another portion of the operation knob 310 extends into the inner cavity through the second opening, so as to be matched with other components of the driving mechanism 300.

The worm 320, the transmission wheel 330, the rocker assembly 340 and the rack 350 are all located in the inner cavity, the rocker assembly 340 comprises a rocker 341 and a first gear 342, one end of the rocker 341 is fixedly connected with the first gear 342, and specifically, the rocker 341 and the first gear 342 are an integral structural member. The rocking bar 341 is hinged with the apparatus casing 100, and thus the first gear 342 rotates along with the rocking bar 341 when the rocking bar 341 rotates.

The operation knob 310 is connected to the transmission wheel 330 through the worm 320, the transmission wheel 330 is provided with a connection shaft 331, the rocking bar 341 is provided with a sliding groove 3411, the extending direction of the sliding groove 3411 is the same as the extending direction of the rocking bar 341, the connection shaft 331 is in sliding fit with the sliding groove 3411 in the extending direction of the rocking bar 341, and the connection shaft 331 is in rotating fit with the sliding groove 3411.

When the transmission wheel 330 rotates, the connection shaft 331 can rotate around the rotation center of the transmission wheel 330, and the connection shaft 331 can also slide in the sliding groove 3411. When the connecting shaft 331 slides in the sliding groove 3411, the rocking bar 341 can be driven to rotate, so that the rocking bar 341 can drive the first gear 342 to rotate.

It should be noted that the connecting shaft 331 is eccentrically disposed on the transmission wheel 330, so that the rotation of the rocking bar 341 can be realized. The first gear 342 meshes with a rack 350, and the rack 350 is connected to the function module 200. The operation knob 310 drives the transmission wheel 330 to rotate through the worm 320, the transmission wheel 330 drives the rocker 341 to rotate, the rocker 341 drives the first gear 342 to rotate, and the first gear 342 drives the function module 200 to move through the rack 350.

In a specific operation process, when the function module 200 needs to be switched to an operating state, a user rotates the operation knob 310, the operation knob 310 drives the worm 320 to rotate, the worm 320 drives the transmission wheel 330 to rotate, one end of the rocker 341 is fixedly connected with the first gear 342, at this time, the transmission wheel 330 rotates, the connecting shaft 331 rotates around the rotation center of the transmission wheel 330, and the connecting shaft 331 can slide in a sliding manner, because the rocker 341 is hinged to the device housing 100, the transmission wheel 330 drives the rocker 341 to rotate around the hinge shaft of the rocker 341 and the device housing 100, the rocker 341 drives the first gear 342 to rotate, the first gear 342 drives the rack 350 to move towards the first opening, so that the rack 350 drives the function module 200 to move, and at least a part of the function module 200 extends out of the device housing 100 through the first opening.

When the function module 200 is finished, the user rotates the operation knob 310 again, the operation knob 310 drives the worm 320 to rotate, the worm 320 drives the transmission wheel 330 to rotate, at this time, the transmission wheel 330 drives the rocker 341 to rotate around the hinge shaft of the rocker 341 and the device housing 100, the rocker 341 drives the first gear 342 to rotate, the first gear 342 drives the rack 350 to move in the direction away from the first opening, so that the rack 350 drives the function module 200 to move, and the function module 200 retracts into the device housing 100 through the first opening.

The first gear 342 and the rocker 341 may be integrally formed, or the first gear 342 and the rocker 341 may be connected by bonding, welding, or the like, of course, other methods may also be used, and the specific structure of the rocker assembly 340 is not limited herein.

The operation knob 310 is capable of rotating in a first direction and a second direction, and in the case where the operation knob 310 rotates in the first direction, at least a part of the function module 200 protrudes out of the apparatus case 100 through the first opening; when the operation knob 310 is rotated toward the second direction, the function module 200 is retracted into the apparatus housing 100 through the first opening. The first direction and the second direction may be opposite or the same. For example, the first direction and the second direction may be both clockwise or both counterclockwise, and of course one of the first direction and the second direction may be counterclockwise and the other may be clockwise.

Specifically, the functional module 200 may include at least one of a camera module, a fingerprint identification module, a telephone receiver, a light supplement lamp, a card holder, a speaker, a microphone, and a sensor, and may also include other components that can enter and exit the device housing 100.

In the embodiment disclosed in the present application, the functional module 200 is disposed in the inner cavity of the device housing 100, when the functional module 200 works, the driving mechanism 300 drives the functional module 200 to extend out of the device housing 100, when the functional module 200 does not work, the driving mechanism 300 drives the functional module 200 to retract into the device housing 100, so that the functional module 200 is hidden in the inner cavity of the device housing 100, and thus the functional module 200 does not occupy the display area of the electronic device, and further the screen occupation ratio of the electronic device is large.

In addition, the process of the functional module 200 entering or exiting the device housing 100 can be completed only by applying an external force by a user, so that the problem of power consumption does not exist, and the energy consumption of the electronic device can be reduced. The electronic equipment does not need a driving motor and other parts with higher price, so that the production cost can be reduced. Meanwhile, the driving of the movement of the functional module 200 is realized manually by the user, so that the mechanical operation experience of the user can be improved undoubtedly.

Further, the transmission wheel 330 can provide a supporting force to the function module 200 without rotating, so that the function module 200 can be held at the position, and thus the function module 200 can be held at the position when being extended out of the apparatus case 100.

In the above embodiment, the connecting shaft 331 can slide in the sliding groove 3411 and rotate in the sliding groove 3411, so that the connecting shaft 331 and the sliding groove 3411 are not easily jammed, and further the rocking bar 341 rotates more smoothly, and the function module 200 can extend out or retract into the device housing 100 more easily, thereby improving the reliability of the electronic device.

Alternatively, the connecting shaft 331 and the driving wheel 330 may be integrally formed, or the connecting shaft 331 and the driving wheel 330 may be connected by bonding or welding, and of course, the connecting shaft 331 and the driving wheel 330 may also be connected by other connecting methods, which is not limited herein.

Specifically, since the rocker 341 drives the first gear 342 to swing within a certain range, the first gear 342 may be a sector gear, so that the structure of the driving mechanism 300 is more compact. It should be noted that the rotation range of the first gear 342 should ensure that the function module 200 can be extended out of the apparatus casing 100 or the function module 200 can be retracted into the apparatus casing 100.

In another alternative embodiment, the driving mechanism 300 may further comprise a gear mechanism 360, the gear mechanism 360 may comprise a second gear 361 and a third gear 362, the third gear 362 is engaged with the worm 320, the second gear 361 is engaged with the third gear 362, the second gear 361 is fixedly connected with the transmission wheel 330, the second gear 361 is coaxially arranged with the transmission wheel 330, and the second gear 361 and the transmission wheel 330 rotate at the same speed.

In a specific operation process, the worm 320 drives the third gear 362 to rotate, the third gear 362 drives the second gear 361 to rotate, and the second gear 361 is fixedly connected with the transmission wheel 330, so the transmission wheel 330 can drive the transmission wheel 330 to rotate, and the transmission wheel 330 can drive the rocker 341 to rotate.

In this scheme, the driving wheel 330 and the worm 320 are connected through the gear mechanism 360, and the driving mechanism 300 has more parts, so that the mounting positions of the driving wheel 330 and the worm 320 are more flexible.

Further, the diameter of the third gear 362 may be larger than the diameter of the second gear 361. In this embodiment, the rotation speed of the second gear 361 is greater than that of the third gear 362, so that the rotation speed of the transmission wheel 330 can be increased, and the moving speed of the functional module 200 can be increased.

Of course, the transmission wheel 330 and the worm 320 may also adopt other transmission manners, for example, the transmission wheel 330 may be a gear, and the transmission wheel 330 and the worm 320 may be engaged, so that the worm 320 may directly drive the transmission wheel 330 to rotate. The specific transmission manner of the transmission wheel 330 and the worm 320 is not limited herein.

Alternatively, the transmission wheel 330 and the second gear 361 may be integrally formed, or the second gear 361 and the transmission wheel 330 may be connected by bonding or welding.

Further, the diameter of the transmission wheel 330 may be larger than the diameter of the second gear 361. In this embodiment, the rotation speeds of the second gear 361 and the transmission wheel 330 are the same, but the diameter of the transmission wheel 330 is larger than the diameter of the second gear 361, so the linear velocity of the transmission wheel 330 is larger, and the moving path of the rack 350 is longer, thereby further increasing the speed of the function module 200 entering or exiting the device housing 100.

In the above embodiment, the rocker 341 and the second gear 361 may be located on the same side of the transmission wheel 330, and this arrangement is easy to make the rocker 341 possibly interfere with the second gear 361 during the rotation process. Based on this, in another alternative embodiment, the rocking bar 341 and the second gear 361 may be respectively located at two sides of the transmission wheel 330, in this scheme, the rocking bar 341 and the second gear 361 are far away, so that the rocking bar 341 does not easily interfere with the second gear 361 during the rotation process.

In order to prevent the functional module 200 from deflecting during movement, in an alternative embodiment, the driving mechanism 300 may further include a guide rod 370, the guide rod 370 may be disposed in the inner cavity, and the guide rod 370 may be slidably connected with the functional module 200 in the movement direction of the functional module 200. In this embodiment, the guide bar 370 can assist in limiting the moving direction of the functional module 200, so as to prevent the functional module 200 from deviating during the moving process, and promote higher moving precision of the functional module 200, thereby improving the reliability of the electronic device.

In the above embodiment, when the guide bar 370 and the rack 350 are both disposed on the same side of the function module 200, the guide bar 370 is closer to other components of the driving mechanism, so that the guide bar 370 and other components of the driving mechanism 300 may interfere easily, for example, the guide bar 370 and the rocking bar 341, the transmission wheel 330, and the like. To this end, in another alternative embodiment, the rack 350 and the guide bar 370 may be respectively located at both sides of the function module 200, and the function module 200 may be located between the rack 350 and the guide bar 370. The components such as the guide bar 370 and the transmission wheel 330 are distributed on two sides of the function module 200, so that the distance between the guide bar 370 and the components such as the transmission wheel 330 is relatively long, and the guide bar 370 and other components of the driving mechanism 300 are not easily interfered. In addition, the guide bar 370 and the rack 350 are located on two sides of the functional module 200, so that the forces on the two sides of the functional module 200 are balanced, and the possibility that the functional module 200 is stuck to the device housing 100 is reduced.

In the above embodiment, when the function module 200 is retracted into the device housing 100, the function module 200 is easily separated from the guide bar 370, and the function module 200 and the guide bar 370 are failed to cooperate, which results in damage to the electronic device. For this purpose, in an alternative embodiment, the guide rod 370 may be provided with a first position-limiting portion 381, the first position-limiting portion 381 may be located at an end of the guide rod 370 facing away from the first opening, and the first position-limiting portion 381 and the function module 200 are in position-limiting fit in the retraction direction of the function module 200. In this scheme, when the functional module 200 retracts to the preset position, the first limit portion 381 can block the functional module 200 from moving, so that the first limit portion 381 can prevent the functional module 200 from separating from the guide rod 370, and further can effectively prevent the possible matching failure of the functional module 200 and the guide rod 370, and further improve the reliability and safety of the electronic device, and meanwhile, the excessive retraction of the functional module 200 can be avoided, and the collision with other components of the electronic device is caused. Alternatively, the first position-limiting portion 381 may be a first position-limiting protrusion, and the first position-limiting protrusion is in position-limiting engagement with the surface of the function module 200 in the retraction direction of the function module 200.

Of course, the problem of the guide bar 370 failing to fit with the function module 200 may also occur when the function module 200 is being extended out of the device housing 100. Therefore, the guide bar 370 may also be provided with a second limiting portion 382, the second limiting portion 382 may be located at an end of the guide bar 370 close to the first opening, and the second limiting portion 382 is in limiting fit with the function module 200 in the extending direction of the function module 200. In this scheme, when the functional module 200 stretches out to the assigned position, the second limiting portion 382 can hinder the functional module 200 from moving, so that the possible cooperation failure of the functional module 200 and the guide rod 370 can be effectively prevented, the safety and the reliability of the electronic device are improved, and the excessive stretching out of the functional module 200 can be avoided. Alternatively, the second limiting portion 382 may be a second limiting protrusion, and the second limiting protrusion is in limiting fit with the surface of the function module 200 in the extending direction of the function module 200.

In order to improve the usability of the function module 200, in an alternative embodiment, the function module 200 may include a module main body 210 and a bracket 220, the module main body 210 is detachably connected to the bracket 220, a rack 350 is connected to the bracket 220, and the rack 350 drives the bracket 220 to move, so as to drive the module main body 210 to move. The function module 200 may have a first state in which the module main body 210 is coupled to the cradle 220 and a second state in which the function module 200 is in the first state, and the module main body 210 is separated from the cradle 220 and is separated from the equipment enclosure 100. In this scheme, when the module main body 210 is separated from the device case 100, the module main body 210 can work independently, so that the function module 200 is not limited by orientation and angle when in use, and therefore, the function module 200 has a high degree of freedom in operation, so that the function module 200 can work while being separated from the device case 100. Herein, the independent operation means that the module main body 210 can be operated in a state of being separated from the bracket 220.

Optionally, the module main body 210 may be provided with a first clamping portion, and the bracket 220 may be provided with a second clamping portion, the first clamping portion being in clamping fit with the second clamping portion. The scheme has simple structure and convenient disassembly. The first clamping portion can be a clamping hook, the second clamping portion can be a clamping groove, the clamping hook is matched with the clamping groove in a clamping mode, or the first clamping portion and the second clamping portion are both clamping hooks, and specific structural texts of the first clamping portion and the second clamping portion are not limited.

In the above embodiment, the first clamping portion and the second clamping portion are easily damaged in a long-time and high-frequency disassembling process, so that the reliability of the electronic device is reduced. For this reason, in another alternative embodiment, one of the module body 210 and the bracket 220 may be provided with a magnetic member, and the other may be provided with a magnetic member, and the magnetic member are magnetically engaged. In this scheme, magnetism spare and magnetism are inhaled the piece and are difficult to damage, and then can improve electronic equipment's reliability. Optionally, the magnetic member may be a permanent magnet, and the magnetic member may be a metal member magnetically attracted to the magnetic member, or of course, the magnetic member may also be a permanent magnet.

It should be noted that, herein, the magnetic member refers to a structural member with magnetism, and the magnetic member is a structural member capable of being magnetically attracted by the magnetic member, such as an iron member.

In the above embodiment, when the projection profile of the operation knob 310 in the axial direction of the second opening is smaller than the projection profile of the second opening, the operation knob 310 is easily pushed into the inner cavity, so that it is difficult for the user to rotate the operation knob 310, and further the function module 200 is difficult to drive, which undoubtedly brings inconvenience to the user. Based on this, in another alternative embodiment, the operation knob 310 may include a connection portion 311 and an operation portion 312, the connection portion 311 is connected to the operation portion 312, a portion of the connection portion 311 may extend into the inner cavity through the second opening, the connection portion 311 is connected to the worm 320, at least a portion of the operation portion 312 is located outside the device housing 100, and the operation portion 312 is in limit fit with the outer surface of the device housing 100 in the axial direction of the second opening. In this scheme, the operation portion 312 is in limit fit with the outer surface of the device housing 100, and the projection profile of the second opening in the axial direction is located within the projection profile of the operation portion 312, at this time, the device housing 100 can block the operation portion 312 from entering the inner cavity, so that the operation portion 312 can be prevented from being pushed into the inner cavity, and further the operation knob 310 can be rotated easily by a user, thereby facilitating the driving of the function module 200.

In the above embodiment, the first opening and the second opening may be located on the same side of the device housing 100, where the side is an outer surface of the device housing 100, and at this time, the functional module 200 and the driving mechanism 300 are likely to interfere with each other, and at the same time, the local strength of the device housing 100 is too low. For this reason, in another alternative embodiment, the first opening and the second opening may be respectively disposed on two opposite sides of the device housing 100, and an axis of the first opening and an axis of the second opening may be disposed in a staggered manner. In this scheme, first opening and second opening can be located two different sides to make functional module 200 and actuating mechanism 300 be difficult to take place to interfere when the installation, also make things convenient for waterproof, dustproof design simultaneously.

The electronic device disclosed in the embodiment of the present application may further include a connection band 400, where the connection band 400 is connected to the device housing 100, and the connection band 400 is used for enabling the electronic device to be worn on a human body. For example, in the case where the electronic device is a wristwatch, the connection band 400 may be a watch band, and the device body may be a dial. In the embodiment of the present application, the type of the connection band 400 may be various, for example, the connection band 400 may be a leather band, a metal band, or the like, and the embodiment of the present invention does not limit the specific type of the connection band 400.

In the above-described embodiment, when the first opening is located close to the connection strap 400, the functional module 200 easily interferes with the connection strap 400 when protruding out of the apparatus case 100, thereby easily causing damage to the functional module 200. In an alternative embodiment, an avoiding groove may be formed at one end of the connection belt 400 connected to the equipment enclosure 100, and at least a part of the function module 200 may be located in the avoiding groove under the condition that at least a part of the function module 200 extends out of the equipment enclosure 100.
