Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 17, an embodiment of the invention discloses an electronic device, which includes a housing 100, a motion module 200, a first elastic driving element 300, a rack 500, and a rotating element 600.

The housing 100 is a base member of the electronic apparatus, and the housing 100 provides a mounting base for other components of the electronic apparatus. In the embodiment of the present invention, the motion module 200, the rack gear 500, and the rotation member 600 are directly or indirectly mounted to the housing 100. The housing 100 of the embodiment of the invention has the opening 111, and the opening 111 is communicated with the inner cavity 120 of the housing 100, so that the position of the motion module 200 can be conveniently switched between the inner cavity 120 and the outside of the housing 100 through the opening 111. In a normal case, the casing 100 has a center frame 110, and the opening 111 is opened in the center frame 110. Of course, the opening 111 may be opened at other positions of the housing 100, and the specific position of the opening 111 is not limited in the embodiments of the present invention.

The motion module 200 is disposed on the housing 100, and in the embodiment of the present invention, the motion module 200 needs to extend out of the housing 100 for operation. The motion module 200 is capable of moving relative to the housing 100, and the motion module 200 can be retracted into the internal cavity 120 or at least partially extended out of the housing 100 through the opening 111, thereby moving between the extended position and the retracted position. When the motion module 200 is in the extended position, the motion module 200 is at least partially outside the housing 100; when the motion module 200 is in the retracted position, the motion module 200 is located inside the housing 100, thereby achieving concealment inside the housing 100.

In the embodiment of the present invention, the motion module 200 is a semi-automatic structure, i.e. the user can manually operate the motion module 200 to at least partially extend from the housing 100, and can manually operate the motion module 200 to retract into the housing 100. In a specific operation process, the user manually presses the one-time motion module 200, the motion module 200 retracts into the housing 100, the user manually presses the one-time motion module 200 again, and the motion module 200 at least partially extends out of the housing 100, so that the operation can be repeated. The structure for implementing the motion of the motion module 200 can be various, for example, the motion module 200 can adopt a pop-up structure similar to a semi-automatic pen, which is a known technology and will not be described herein.

Specifically, the first elastic driving element 300 is disposed in the housing 100, and the first elastic driving element 300 can drive at least a portion of the motion module 200 to extend out of the housing 100 through the opening 111. Specifically, the first elastic driving element 300 can be extended and moved by pulling the movement module 200, and certainly, the first elastic driving element 300 can also be retracted and moved by pushing the movement module 200.

In the embodiment of the present invention, the motion module 200 may include at least one of a camera, a flash, a fingerprint recognition module, and a microphone. Of course, the motion module 200 may also include other kinds of functional devices, and the embodiment of the invention does not limit the specific kind of the motion module 200.

One of the housing 100 and the motion module 200 is provided with a rack 500, and the rack 500 extends in a moving direction of the motion module 200. The other one of the housing 100 and the motion module 200 is rotatably provided with a rotation member 600, and the rotation member 600 has gear teeth engaged with the rack gear 500. During the movement of the motion module 200, the motion module 200 can move relative to the rotation member 600. Specifically, the rotation member 600 may be a gear. Specifically, the rotating member 600 may be mounted on the housing 100 or the moving module 200 through a bearing or a direct shaft hole, so as to rotatably mount the rotating member 600.

In the electronic device disclosed in the embodiment of the present invention, one of the housing 100 and the motion module 200 is provided with the rack 500, the other is rotatably provided with the rotating member 600, and the rotating member 600 is engaged with the rack 500 through the gear teeth, so that the engagement between the rotating member 600 and the rack 500 plays a role in resistance increase in the moving process of the motion module 200, so that the motion module 200 can move relatively stably, the problem of large inertia caused by an excessively high motion speed of the motion module 200 is avoided, and further, the impact generated between the motion module 200 and the housing 100 in the ejection process can be alleviated.

In a more preferable embodiment, the rotation member 600 may be disposed on the motion module 200 so as to be rotatable on the motion module 200. Accordingly, the rack 500 may be provided on the housing 100. Specifically, the rack 500 may be fixed in the housing 100 by screws. Since the rack 500 is bulky and heavy, the rack 500 disposed on the motion module 200 may cause the motion module 200 to be too heavy and have poor moving performance. The installation position of the housing 100 is easy to design and is suitable for assembling the rack 500. In this preferred embodiment, the rotation member 600 is disposed on the motion module 200, and the rack 500 is mounted in the housing 100, which not only has less influence on the motion module 200, but also facilitates the assembly of the rack 500.

In order to further improve the stability of the movement of the motion module 200, in a preferable embodiment, a second guide rail 700 may be disposed in the housing 100, the second guide rail 700 may extend along the movement direction of the motion module 200, the motion module 200 is slidably engaged with the second guide rail 700, and the motion module 200 has higher movement precision under the guidance of the second guide rail 700.

Under the premise that the rotation member 600 is disposed at the motion module 200 and the rack 500 is installed in the housing 100, in a more preferable scheme, the rack 500 and the second guide rail 700 may be respectively disposed at both sides of the motion module 200, a guide space may be formed between the rack 500 and the second guide rail 700, and the motion module 200 is slidably disposed in the guide space, thereby facilitating the motion module 200 to perform more stable and accurate motion.

As described above, the structure of the manual operation and control motion module 200 may be various, referring to fig. 8 to 10 again, the motion module 200 may include the first guide rail 210, and the first guide rail 210 may include the first limiting section 211, the extending section 212, the second limiting section 213 and the retracting section 214, which are sequentially connected to form a ring shape. The protruding section 212 and the retracting section 214 each function to connect the first stopper section 211 and the second stopper section 213. Specifically, the opposite ends of the first position-limiting section 211 and the second position-limiting section 213 are connected by the extending section 212, and the other ends of the first position-limiting section 211 and the second position-limiting section 213 are connected by the retracting section 214.

On the premise that the motion module 200 has the first guide rail 210 with the above structure, the electronic device disclosed in the embodiment of the present invention may further include a limiting mechanism 400.

As mentioned above, the first elastic driving member 300 is disposed in the housing 100, and the first elastic driving member 300 can drive at least a portion of the motion module 200 to extend out of the housing 100 through the opening 111, so as to be located at the extended position. That is, the direction of the elastic force applied by the first elastic driving member 300 is consistent with the extending direction of the motion module 200. Specifically, the first elastic driving element 300 may be a helical expansion spring, or may be an elastic rubber element, and the embodiment of the invention does not limit the specific kind of the first elastic driving element 300.

The limiting mechanism 400 may include a limiting portion 410, the limiting portion 410 is rotatably disposed in the housing 100, and the limiting portion 410 is slidably engaged with the first guide rail 210, so as to be capable of sliding to various portions of the first guide rail 210 during the movement of the motion module 200. Specifically, the limiting portion 410 can be in adaptive sliding fit with the first limiting section 211, the extending section 212, the second limiting section 213 and the retracting section 214 through rotation, and the motion module 200 can be maintained at the set position, i.e., the extending position and the retracting position, through the fit of the limiting portion 410 and the first limiting section 211 and the fit of the limiting portion 410 and the second limiting section 213.

It should be noted that, herein, the first limiting section 211, the extending section 212, the second limiting section 213 and the retracting section 214 are sequentially connected to form a ring shape, which means that, when the motion module 200 is continuously pressed by a user, the limiting portion 410 can slide relative to the first guide rail 210, can enter the extending section 212 from the first limiting section 211, can enter the second limiting section 213 from the extending section 212, and can enter the retracting section 214 from the second limiting section 213 and enter the first limiting section 211 from the retracting section 214, and sequentially circulates along with the pressing. The extending section 212 and the retracting section 214 play a guiding role, so that the limiting part 410 can be switched and matched between the first limiting section 211 and the second limiting section 213.

As described above, the motion module 200 is movable to change positions between the extended position and the retracted position. When the motion module 200 is in the extended position, at least a portion of the motion module 200 is located outside the housing 100, the limiting portion 410 is engaged with the first limiting section 211 to limit the motion module 200 from moving toward the opening 111, and the engagement of the limiting portion 410 and the first limiting section 211 can maintain the motion module 200 in the extended position. With the motion module 200 in the retracted position, the motion module 200 is located inside the housing 100, and the limiting portion 410 cooperates with the second limiting section 213 to limit the motion module 200 from moving toward the opening 111. The acting force of the limiting portion 410 on the motion module 200 is opposite to the direction of the elastic force exerted by the first elastic driving member 300, so that the motion module 200 can be maintained at the corresponding position.

In the using process, after the motion module 200 is completed, the user can manually press the motion module 200, so as to overcome the elastic force of the first elastic driving member 300, the limiting portion 410 can slide from the first limiting section 211 to the position matched with the second limiting section 213 through the retracting section 214, and at the same time, the motion module 200 can retract into the housing 100 through the opening 111, and the motion module 200 can be kept at the retracting position under the elastic force action of the first elastic driving member 300 and the action matched with the second limiting section 213; when the motion module 200 needs to work, the user can manually press the motion module 200 again, so as to overcome the elastic force of the first elastic driving member 300, the limiting portion 410 can slide from the second limiting section 213 to the position matched with the first limiting section 211 through the extending section 212, at least part of the motion module 200 can extend out of the housing 100 through the opening 111, and under the elastic force action of the first elastic driving member 300 and the action of the first limiting section 211, the motion module 200 can be kept at the extending position, so that the motion module 200 can work.

Through the above working process, the motion module 200 is switched between the extended position and the retracted position by the first elastic driving member 300 and the limiting mechanism 400, no matter at least part of the motion module 200 is controlled to extend out of the housing 100 or retract into the housing 100 through the motion module 200, only the user needs to press the motion module 200, and the whole operation process has no power consumption problem, so that the energy consumption of the electronic device can be reduced.

As described above, the position limiting portion 410 can maintain the position of the motion module 200, and the structure of the position limiting portion 410 may be various. Specifically, the position-limiting portion 410 may be a hook, which is hooked to the first position-limiting section 211 and the second position-limiting section 213 respectively, so as to realize the position-limiting cooperation with the first position-limiting section 211 and the second position-limiting section 213 respectively. The first position-limiting section 211 and the second position-limiting section 213 can be engaged with the hook, for example, the first position-limiting section 211 and the second position-limiting section 213 can be engaging recesses.

Referring to fig. 6, 7, 11, 12, and 13 to 16 again, in the case that the limiting portion 410 is a hook, the limiting mechanism 400 disclosed in the embodiment of the present invention may further include a mounting bracket 420 and a hook bracket 430, the mounting bracket 420 is mounted in the housing 100, the hook is connected to the hook bracket 430, and the hook bracket 430 is rotatably connected to the mounting bracket 420, so that the hook bracket 430 drives the hook to rotate relative to the mounting bracket 420, and thus the first guide rail 210 can be better adapted to.

Specifically, the hook bracket 430 may be hinged to the mounting bracket 420 via a second hinge shaft 460. The mounting bracket 420 may be secured in the interior cavity 120 of the housing 100 by screws. Specifically, the second hinge shaft 460 may be a second screw, specifically, the second screw may be fixed on the housing 100, and the hook bracket 430 may be rotatably connected to the second screw.

In the process of the movement module 200, the position-limiting portion 410 may be separated from the first guide rail 210, and in order to realize a more stable sliding fit, in an optimal scheme, the position-limiting mechanism 400 may further include a second elastic driving member 440, the draw hook may be hinged to the draw hook bracket 430, the second elastic driving member 440 is connected to the draw hook, and the second elastic driving member 440 drives the draw hook to cling to the first guide rail 210, so as to improve the stability of the sliding fit.

Specifically, the retractor can be hinged to the retractor bracket 430 through the first hinge shaft 450, and the second elastic driving member 440 can be various types of elastic bodies. The second elastic driving member 440 can be a second torsion spring, the second torsion spring can be disposed on the first hinge shaft 450 in a penetrating manner, one end of the second torsion spring is positioned on the hook support 430, the other end of the second torsion spring is connected with the hook, and the hook is driven to attach to the first guide rail 210. In this case, in the case where the second elastic driving member 440 is the second torsion spring, it is possible to certainly achieve a more compact assembly. Specifically, the first hinge shaft 450 may be a first screw. Specifically, the threaded section of the first screw may be fixed to the hook bracket 430, and the polished rod section of the first screw may be hinged to the hook, as shown in fig. 1.

In a more preferable embodiment, the hook bracket 430 may include two connecting arms 431 disposed side by side, the hook may be disposed between the two connecting arms 431, the first hinge shaft 450 may pass through the hook and the two connecting arms 431, and in this case, the hook bracket 430 is connected between the two connecting arms 431, which can certainly improve the connection stability of the hook bracket 430.

In the embodiment of the present invention, the draw hook may be at least partially located in the space covered by the mounting bracket 420, and the draw hook may be in limit fit with the mounting bracket 420, so that under the action of the mounting bracket 420, the separation between the draw hook and the first rail 210 can be further avoided.

Referring to fig. 1 to 17 again, in a preferred embodiment, the first elastic driving member 300 may be a first torsion spring, a first elastic end of the first torsion spring may be positioned on the housing 100, and a second elastic end of the first torsion spring may be connected to the moving module 200. Under normal conditions, the second elastic end of the first torsion spring contacts the motion module 200 to drive the motion module 200. Due to the special structure of the torsion spring, the first elastic end of the first torsion spring and the second elastic end of the first torsion spring can be designed to be longer structures, so that the elastic matching between the first elastic end of the first torsion spring and the shell 100 and between the second elastic end of the first torsion spring and the motion module 200 can be easily realized, and meanwhile, the arrangement of the first torsion spring in the inner cavity 120 can be more freely realized.

In an actual assembling process, the first elastic end of the first torsion spring may contact the housing, and the second elastic end of the first torsion spring may contact the motion module 200. Of course, in order to improve the assembling performance, in a more preferable scheme, the housing 100 may be provided with a positioning column 130, and the first torsion spring may be sleeved on the positioning column 130.

To avoid the falling of the first torsion spring, one end of the positioning column 130 may be fixed on the housing 100, and the other end of the positioning column 130 may be provided with a threaded hole. The first torsion spring is sleeved on the positioning column 130 from the other end of the positioning column 130, the first torsion spring can be installed on the positioning column 130 through the screw 140 in threaded fit with the threaded hole, and the nut of the screw 140 can play a role in limiting the first torsion spring, so that the first torsion spring is prevented from falling off from the positioning column 130.

As described above, the second elastic end of the first torsion spring may contact the motion module 200, and in order to apply the elastic force more easily, the motion module 200 may have a stopper 215, and the second elastic end of the first torsion spring may elastically contact the stopper 215, thereby applying the driving force to the motion module 200 through the stopper 215.

As mentioned above, the position-limiting portion 410 may be a hook, and the acting force applied by the hook to the motion module 200 is a pulling force. Of course, the limiting portion 410 may also be an abutting portion that can abut against the first limiting section 211 and the second limiting section 213 for limiting, in this case, the acting force applied by the abutting portion to the motion module 200 may be a pushing force, and similarly, the first limiting section 211 and the second limiting section 213 may be recessed, so as to facilitate the abutting against the abutting portion for limiting. Of course, the first position-limiting section 211 and the second position-limiting section 213 may have other structures as long as they can be in position-limiting fit with the abutting portion, and further keep the motion module 200 in the extended position or the retracted position under the limitation of the abutting portion. In one embodiment, the abutting portion may be a structural member with one end rotatably connected to the housing 100 and the other end slidably engaged with the first guide rail 210.

In the electronic device disclosed in the embodiment of the present invention, the first guide rail 210 may have a plurality of structures, and in a specific implementation manner, the first guide rail 210 may be a guide groove, that is, the first limiting section 211, the extending section 212, the second limiting section 213, and the retracting section 214 may be each groove section of the guide groove, that is, the first limiting section 211 is communicated with the extending section 212, the extending section 212 is communicated with the second limiting section 213, the second limiting section 213 is communicated with the retracting section 214, and the retracting section 214 is communicated with the first limiting section 211. In this case, the position-limiting portion 410 can slide in the guide groove, which certainly improves the stability of the sliding fit, and certainly facilitates the movement module 200 to be maintained at the extended position or the retracted position.

Specifically, the first limiting section 211, the extending section 212, the second limiting section 213 and the retracting section 214 may be groove sections with various structures, please refer to fig. 8 to 10 again, the extending section 212 may be a linear groove section, so as to achieve the extending of the motion module 200 more quickly. In a more preferred aspect, the retraction section 214 can include an arcuate slot section. Because the user needs to press for a longer time in the retraction process of the motion module 200, the arc-shaped groove section has a certain curvature, so that the position of the limiting part 410 can be better guided to the position matched with the first limiting section 211.

In order to better realize the limit fit, the first limit section 211 may be a groove section bent toward the extending direction away from the motion module 200, for example, the through axis of the first limit section 211 is a V-shaped broken line; similarly, the second position-limiting section 213 may also be a groove section that bends toward the extending direction away from the motion module 200, for example, the through axis of the second position-limiting section 213 is a V-shaped broken line; in this case, the first position-limiting section 211 and the second position-limiting section 213 can be more stably engaged with the position-limiting portion 410.

Of course, the first rail 210 may have other configurations, and is not limited to a channel-like configuration. Referring to fig. 17, in a specific embodiment, the first guide rail 210 may be a convex guiding portion, the first limiting section 211, the extending section 212, the second limiting section 213 and the retracting section 214 are convex sections, the sliding stroke of the limiting portion 410 may be as shown in fig. 17, and the sliding direction of the limiting portion 410 relative to the first guide rail 210 is schematically shown by a dotted arrow in fig. 13.

Similarly, the first limiting section 211 may be a strip-shaped protrusion bent toward the direction away from the moving direction of the moving module 200; the second position-limiting segment 213 may be another strip-shaped protrusion bent toward the direction away from the moving direction of the moving module 200.

The electronic equipment disclosed by the embodiment of the invention can be equipment such as a smart phone, a tablet computer, an electronic book reader, wearable equipment and the like, and the specific type of the electronic equipment is not limited by the embodiment of the invention.

In the above embodiments of the present invention, the difference between the embodiments is mainly described, and different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory, and further description is omitted here in view of brevity of the text.

While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
