[0001] Cross-reference to related applications

[0002] The present application claims priority from a Chinese patent application No. 202010241344.7 filed on March 30, 2020, and entitled "Electronic device", the content of which is incorporated herein in its entirety. TECHNICAL FIELD

[0003] The present application relates to the field of communication technology, and in particular to an electronic device. BACKGROUND

[0004] With the increasing functions of electronic devices (such as mobile phones, tablets), the functional devices configured on the electronic devices are also increasing, which brings great challenges to the assembly of the electronic devices. With the increasing demand of users for the appearance of electronic devices, users are increasingly favoring electronic devices with a large screen ratio.

[0005] Taking a camera as an example, in order to increase the screen ratio of the electronic device, the camera of the current electronic device is a lifting camera, which is driven by a driving mechanism arranged inside the shell of the electronic device, and then enters or exits the shell. When the user needs to take a picture, the driving mechanism is controlled to drive the lifting camera to extend out of the shell, and then take a picture. After the shooting is completed, the driving mechanism is controlled to drive the lifting camera to retract into the shell, achieving the purpose of hiding the camera. This electronic device can avoid the occupation of the camera to the plate space, thereby increasing the screen ratio of the electronic device.

[0006] In the current electronic device, the functional components that need to make telescopic motion in the electronic device need to be driven by a driving mechanism. The driving mechanism includes a motor, which needs to be configured with a relatively complex transmission mechanism, which usually includes a screw nut guide rod, a spring guide rod and the like, which are used to guide the movement of the functional components during the driving process, so as to limit the running direction of the functional components inside the electronic device. However, these devices all need to occupy the space inside the electronic device, thus resulting in the occupation of a large internal space in the electronic device by the driving components.

[0007] SUMMARY

[0008] The present application discloses an electronic device to solve the problem of large space occupied by the driving mechanism of the electronic device.

[0009] In order to solve the above problems, the present application adopts the following technical solutions:

[0010] An electronic device comprises a housing provided with an opening, a functional module capable of being retracted into the housing or extended out of the housing through the opening, and a driving mechanism arranged in the housing, the driving mechanism comprising a driving source, a lead screw, a nut sleeve set and a caliper, the driving source being in driving connection with the lead screw, the nut sleeve set comprising a matching part in threaded connection with the lead screw, the first end of the caliper being in position-limiting connection with the matching part, and the second end of the caliper being fixedly connected with the functional module, wherein the matching part has a polygonal cross section.

[0011] The technical scheme adopted by the present application can achieve the following beneficial effects:

[0012] In the electronic device disclosed by the present application, the driving mechanism comprises a driving source, a lead screw, a nut sleeve set and a caliper, the first end of the caliper is in position-limiting connection with the matching part, and the matching part has a polygonal cross section, so that the rotation of the matching part is limited by the caliper, thereby enabling the matching part to drive the caliper to move along the lead screw only and unable to rotate together with the lead screw, and thus the structure can realize the transmission of driving force and the limitation of rotation of the matching part simultaneously through the cooperation between the caliper and the matching part, and the electronic device can save the additional structure for guiding, so that the space occupied by the driving mechanism is smaller.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0022] As shown in FIGS. 1-5, the electronic device includes a housing 100, a functional module 200, and a driving mechanism.

[0023] The housing 100 can serve as a main structure of the electronic device, and can provide a mounting basis for other components of the electronic device. The housing 100 is provided with an opening 110 through which the functional module 200 can enter or exit the housing 100. Optionally, the housing 100 can include a bezel, and the opening 110 can be disposed on the bezel.

[0024] The functional module 200 can be retracted into the housing 100 or extended out of the housing 100 through the opening 110. Optionally, the functional module 200 can include a bracket 210 and functional devices disposed on the bracket 210. When the functional module 200 is retracted into the housing 100 through the opening, the functional module 200 can be in a non-working state, and at this time, the functional module 200 is hidden in the housing 100. When the functional module 200 is extended out of the housing 100 through the opening 110, the functional module 200 can be in a working state, and when the functional module 200 finishes working, it can be retracted into the housing 100 through the opening. Such a functional module 200 can not occupy the display area of the electronic device, and thus the screen-to-body ratio of the electronic device can be improved. At the same time, the housing 100 does not need to be provided with mounting holes or other structures corresponding to the functional module 200, so that the appearance consistency of the electronic device is better, and the user experience is better. Optionally, the functional module 200 can include at least one of a camera, a sensor, a fingerprint recognition module, a receiver, and a fill light. Of course, the functional module 200 can also include other devices, and the embodiments of the present application do not limit this.

[0025] The driving mechanism is arranged in the shell 100, and the driving mechanism comprises a driving source 310, a lead screw 320, a nut sleeve set and a caliper 370. The driving source 310 is in driving connection with the lead screw 320. The nut sleeve set comprises a matching part 330, which is in threaded cooperation with the lead screw 320. The first end of the caliper 370 is in limiting cooperation with the matching part 330, and the second end of the caliper 370 is fixedly connected with the functional module 200. The cross-sectional shape of the matching part 330 is polygonal, and correspondingly, the cross-sectional shape of the first end of the caliper 370 can also be polygonal, and the shapes of the two are matched. At this time, the caliper 370 can limit the rotation of the matching part 330, so that the first end of the caliper 370 and the matching part 330 are more reliably limited and cooperated. The caliper 370 can be matched with the matching part 330 in a clamping manner, so as to realize the transmission of the force. The caliper 370 and the bracket 210 of the functional module 200 are separately arranged, or the two can be integrally formed. Relatively speaking, when the caliper 370 and the bracket 210 of the functional module 200 are integrally formed, the force can be more efficiently transmitted.

[0026] Optionally, the driving source 310 can adopt a driving motor, or can adopt a piezoelectric element or other structure capable of outputting a driving force. As long as the driving source 310 can output a driving force to drive the lead screw 320 to rotate, the specific form of the driving source 310 is not limited in the embodiment of the present application. The driving source 310 can be arranged between the opening 110 and the matching part 330, so that the structure of the driving mechanism is more compact. In addition, the cross-sectional shape of the matching part 330 can be triangular, rectangular, pentagonal, hexagonal, octagonal, etc. Correspondingly, the cross-sectional shape of the first end of the caliper 370 can be triangular, rectangular, pentagonal, hexagonal, octagonal, etc. Those skilled in the art can understand that the shape of the caliper can match the shape of the matching part 330, that is, the shape of the matching part 330 is quadrangular, and the shape of the caliper 370 is also quadrangular. In other embodiments, the shape of the caliper 370 can also be different from that of the matching part 330, but it should be ensured that at the position where the matching part 330 has an edge, the edge can be matched with the corresponding edge of the caliper 370, and the friction between the two edges needs to be increased to prevent the two from being separated. The cross-sectional shape of the matching part 330 and the cross-sectional shape of the first end of the caliper 370 are not limited in the embodiment of the present application. It should be noted that the cross section is parallel to the thickness direction of the electronic device and perpendicular to the movement direction of the functional module 200.

[0027] When the above scheme is adopted, the driving source 310 can drive the screw rod 320 to rotate. Since the screw rod 320 is threadedly engaged with the matching part 330, and the clamp 370 can limit the rotation of the matching part 330, the matching part 330 can be moved along the screw rod 320 under the driving of the screw rod 320. The matching part 330 can transmit the force to the functional module 200 through the clamp 370, so that the functional module 200 can be moved relative to the shell 100 under the action of the driving mechanism, and then switched between different states.

[0028] In the embodiment of the application, the cross-sectional shape of the matching part 330 is polygonal, so that the rotation of the matching part 330 is limited by the clamp 370, so that the matching part 330 can drive the clamp 370 to move only along the extension direction of the screw rod 320, and cannot rotate together with the screw rod 320. Therefore, the structure can simultaneously achieve the purposes of transmitting the driving force and limiting the rotation of the matching part 330 through the cooperation between the clamp 370 and the matching part 330. The electronic device can omit the special device for guiding, so that the space occupied by the driving mechanism is smaller. At the same time, the weight of the driving mechanism is reduced, so that the weight of the electronic device is reduced, and the thin and light design of the electronic device is more beneficial.

[0029] In a further embodiment, the above screw nut set further comprises an elastic member 350 and a movable baffle 360. The movable baffle 360 is connected to the matching part 330 through the elastic member 350, and is located on the side of the matching part 330 away from the opening 110. The clamp 370 can slide relative to the matching part 330, and moves along the screw rod 320. When the clamp 370 is at least partially separated from the matching part 330, the elastic member 350 drives the movable baffle 360 to make the clamp 370 contact the matching part 330. First, the clamp 370 can slide relative to the matching part 330 while limiting the rotation of the matching part 330, so that a certain movement allowance can be generated at the cooperation position of the two. When the functional module 200 needs to be extended out of the shell 100, the screw rod 320 drives the matching part 330 to move, the matching part 330 drives the movable baffle 360 to move, and when the clamp 370 contacts the movable baffle 360, the movable baffle 360 can drive the clamp 370 to move, thereby driving the functional module 200 to move. Secondly, if the functional module 200 is subjected to an external force, the external force will be transmitted to the movable baffle 360 through the clamp 370, and the movable baffle 360 moves relative to the matching part 330. At this time, the elastic member 350 can be deformed, thereby reducing the movement amount of the matching part 330, or even making the matching part 330 not move, thereby preventing the external force acting on the functional module 200 from damaging the driving mechanism.

[0030] Optionally, the elastic member 350 can be a spring or other elastic component.

[0031] When the functional module 200 is subjected to external force, the caliper 370 will be in contact with the movable baffle 360 and drive the movable baffle 360 to move. If the functional module 200 is subjected to greater external force, the moving range of the caliper 370 is greater, which leads to the caliper 370 being easily separated from the matching part 330, and the force transmission path between the caliper 370 and the matching part 330 is cut off. Therefore, in order to prevent this situation, in an alternative embodiment, the electronic device can further include a detection member and a control member. The detection member is arranged in the shell 100, and in the case that the caliper 370 is at least partially separated from the matching part 330, the detection member is triggered and used to detect the relative distance between the caliper and the matching part. The relative distance can be the distance between the center of gravity of the caliper and the center of gravity of the matching part, or the distance between the first surface of the caliper and the second surface of the matching part, wherein the first surface of the caliper and the second surface of the matching part are coplanar when the caliper and the matching part are not separated. The control member is arranged in the shell 100, and the control member is electrically connected with the detection member and the driving source 310 respectively. In the case that the detection member is triggered, the control member controls the driving source 310 according to the detection result of the detection member, so that the driving source 310 is in the working state. In this embodiment, once the caliper 370 is at least partially separated from the matching part 330, the detection member can be triggered to send a related signal, and the control member can control the driving source 310 to be in the working state according to the signal, so that the matching part 330 moves, thereby making the matching part 330 reliably cooperate with the caliper 370. Further, after the control member controls the driving source 310 to be in the working state, the driving source 310 can retract the functional module 200 into the shell 100 through the caliper 370, thereby preventing the functional module 200 from being continuously subjected to external force, so as to achieve the purpose of protecting the functional module 200.

[0032] The above-mentioned detection member can be installed in the shell 100, and the detection member is close to the matching part 330 and the caliper 370, so as to accurately know the cooperation state of the matching part 330 and the caliper 370. In other embodiments, the detection member can also be installed in the matching part 330, so that the distance between the detection member and the matching part 330 and the caliper 370 is smaller, thereby more accurately knowing the cooperation state of the matching part 330 and the caliper 370, and more quickly responding to the situation that the functional module 200 is subjected to external force.

[0033] It should be noted that the above-mentioned detection member can adopt a position sensor, a proximity switch and the like, and the control member can be a controller and the like, and the embodiments of the present application do not limit the specific types of the detection member and the control member.

[0034] The movable baffle 360 can be arranged above the screw rod 320 as a whole, or the movable baffle 360 is provided with an avoiding hole, one end of the screw rod 320 passes through the avoiding hole, at this time, the size of the movable baffle 360 is larger, which can increase the contact area between the movable baffle 360 and the clamp 370, and is beneficial to the reliable transmission of the acting force between the two, at the same time, the movable baffle 360 will not affect the rotation of the screw rod 320. Alternatively, the shape of the avoiding hole can be matched with the structure of the screw rod 320, for example, the avoiding hole can be a circular hole, the hole diameter of the circular hole can be larger than the outer diameter of the screw rod 320, so that a certain gap can be formed between the two. Of course, the shape can also be rectangular, triangular, etc.

[0035] In order to more reliably play the role of the elastic member 350, the number of the elastic member 350 can be set to be multiple, which includes the first elastic member 351 and the second elastic member 352, one end of the first elastic member 351 and one end of the second elastic member 352 are connected with the movable baffle 360, and the first elastic member 351 and the second elastic member 352 are respectively located on both sides of the screw rod 320. With the increase of the number of the elastic member 350, the connecting points between the movable baffle 360 and the matching part 330 will increase, so that the reliability of the connection between the two is higher, and the structure is more stable. In addition, when the functional module 200 is subjected to external force, the multiple elastic members 350 can absorb more external force, preventing the functional module 200 and the driving mechanism from being damaged.

[0036] The elastic member 350 can be directly connected with the end of the matching part 330 close to the opening 110, when this structure is adopted, because the size of the end of the matching part 330 close to the opening 110 is relatively small, it is not convenient for the connection between the elastic member 350 and the matching part 330. Based on this, in the optional embodiment, the screw nut sleeve group further includes a connecting plate 340, the connecting plate 340 is connected to the end of the matching part 330 close to the opening 110, one end of the first elastic member 351 and one end of the second elastic member 352 are connected with the matching part 330 through the connecting plate 340. When the functional module 200 needs to be retracted into the shell 100 through the opening 110, the driving source 310 drives the matching part 330 to move through the screw rod 320, the connecting plate 340 moves and drives the clamp 370 to move in the direction away from the opening 110, thereby driving the functional module 200 to move into the shell 100.

[0037] The size of the connecting plate 340 is appropriately increased, which can more reliably connect with the elastic member 350 and the clamp 370, and at the same time, it is more convenient to make the extension direction of the elastic member 350 parallel to the moving direction of the functional module 200, so that the elastic member 350 more efficiently transmits the driving force, and better absorbs the external force received by the functional module 200.

[0038] Optionally, the connecting plate 340 and the matching part 330 can be provided separately, that is, the two can be formed separately and then assembled together, or the connecting plate 340 and the matching part 330 are integrally formed, thereby improving the structural strength of the structure formed by the two.

[0039] The elastic member 350 and the caliper 370 are arranged in a relatively concentrated manner, and thus interference between the two is prone to occur. Therefore, in an optional embodiment, the caliper 370 has a recess 372 in which at least a part of the elastic member 350 is located. When the recess 372 is provided, the caliper 370 and the elastic member 350 are less likely to interfere with each other, and thus the two can be arranged more concentratedly, so that the structure formed by the functional module 200 and the driving mechanism is more compact, and the two occupy less space, which is beneficial to the stacking of components in the electronic device.

[0040] When the caliper 370 is limited and matched with the matching part 330, in an optional solution, the caliper 370 can be provided with a matching hole, and the matching part 330 can be matched with the matching hole. In another optional solution, the caliper 370 has a linkage recess 371 that is limited and matched with the matching part 330. The linkage recess 371 can first extend through the caliper 370 in the moving direction of the functional module 200, and can also extend to the surface of the caliper 370 in a direction perpendicular to the moving direction. The structure of the linkage recess 371 is similar to a groove, and the linkage recess 371 is less limited in the assembly direction of the caliper 370, and thus the assembly of the caliper 370 and the driving mechanism is facilitated, and the assembly efficiency of the electronic device is higher.

[0041] The electronic device disclosed in the embodiments of the present application can be a smart phone, a tablet computer, an electronic book reader, a wearable device (for example, a smart watch), an electronic game machine, or the like, and the embodiments of the present application do not limit the specific type of the electronic device.

[0042] In the above embodiments of the present application, the differences between the various embodiments are mainly described, and the optimization features that are different between the various embodiments can be combined to form a more optimal embodiment as long as they are not contradictory. In view of the brevity of the writing, the above will not be described here.

[0043] The above only describes the embodiments of the present application and is not used to limit the present application. The present application can have various changes and modifications for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the scope of the claims of the present application.
