Electronic device

Technical Field

The invention relates to the technical field of communication equipment, in particular to electronic equipment.

Background

With the increase of user demands, the requirements of users on the screen occupation ratio of electronic equipment are higher and higher. The larger screen occupation ratio can not only improve the appearance performance of the electronic equipment, but also improve the display performance of the electronic equipment. In order to achieve the above purpose, more and more electronic devices employ a motion module capable of being lifted, such as a lift-type camera. When the electronic equipment needs to work, the motion module extends out of the shell of the electronic equipment under the driving of the driving mechanism. When the work is finished, the motion module is driven by the driving mechanism to retract into the shell of the electronic equipment, and then the motion module can be hidden. The motion module of this kind of structure can avoid the occupation to electronic equipment's face space, and then can make the area of display screen bigger, reaches the purpose that the increase screen accounts for.

In the actual working process, the motion module needs the drive of the driving mechanism to realize the motion. The driving mechanism generally comprises a motor, a speed reducer, a screw mechanism and other components, and the motor, the speed reducer and the screw mechanism are sequentially in transmission connection, so that the motion module is driven. However, the driving mechanism requires power consumption, which increases power consumption of the electronic device.

In order to solve the problem of large energy consumption, the conventional electronic equipment is generally configured with a mechanism capable of realizing the lifting of the motion module through manual operation. However, in the actual using process, when the electronic device falls down to the ground, the motion module continues to move towards the inside of the housing of the electronic device due to inertia, so that a phenomenon similar to manual pressing by a user is generated, and finally the motion module is mistakenly ejected, which is obviously inconvenient for the user to use.

Disclosure of Invention

The invention discloses electronic equipment, which aims to solve the problem that a manually controlled motion module in the conventional electronic equipment is easy to pop up by mistake when the electronic equipment falls off.

In order to solve the problems, the invention adopts the following technical scheme:

an electronic device, comprising:

a housing provided with an opening;

the movement module is positioned outside the shell when the movement module is at the first position; when the motion module is at the second position, the motion module is positioned in the shell;

the balance lever is rotationally arranged in the shell, and one end of the balance lever is opposite to the motion module;

the balance assembly is arranged between the shell and the other end of the balance lever, and the balance assembly and the motion module are arranged on the same side of the balance lever.

The technical scheme adopted by the invention can achieve the following beneficial effects:

in the electronic device disclosed in the embodiment of the present invention, the balance lever and the balance assembly are additionally provided in the housing, the balance lever can rotate, and one end of the balance lever is opposite to the motion module, in this case, when the electronic equipment falls, the motion module can continuously move into the shell due to inertia, and because one end of the balance lever is opposite to the motion module, therefore, the motion module will interfere with one end of the balance lever in the process of moving into the shell, so that the balance lever has the tendency of rotating, because the balance component is arranged between the shell and the other end of the balance lever, the balance component can prevent the balance lever from rotating, thereby ensuring that the balance lever can prevent the motion module from continuously moving into the shell, thereby avoiding the situation similar to the situation that a user manually presses the motion module, and also avoiding the error ejection of the motion module.

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 16, an embodiment of the present invention discloses an electronic device, which includes a housing 100, a motion module 200, a balance lever 500, and a balance assembly.

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 balance lever 500 and the balance assembly are all mounted on 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 movable relative to the housing 100, the motion module 200 being movable between an extended position (i.e., a first position) and a retracted position (i.e., a second position). When the motion module 200 is at the first position, the motion module 200 is located outside the housing 100; when the motion module 200 is in the second position, the motion module 200 is located inside the housing 100.

In the embodiment of the present invention, the motion module 200 is a semi-automatic structure, and a user can manually operate the motion module 200 to extend from the housing 100 or 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 extends out of the housing 100. The structure for implementing the motion of the motion module 200 may be various, for example, the motion module 200 may adopt a pop-up structure similar to a semi-automatic pen.

In the embodiment of the present invention, the motion module 200 may be a camera, a flash, a fingerprint recognition module, a receiver, or other functional devices, and the embodiment of the present invention does not limit the specific type of the motion module 200.

The balance lever 500 is rotatably disposed within the housing 100, and one end of the balance lever 500 is opposite to the motion module 200. Specifically, one end of the balance lever 500 may contact the motion module 200, or may have a certain distance therebetween.

The balancing assembly is disposed between the housing 100 and the other end of the balancing lever 500. The balance assembly and the motion module 200 are disposed on the same side of the balance lever 500.

In the electronic device disclosed in the embodiment of the present invention, the balance lever 500 can rotate by additionally arranging the balance lever 500 and the balance component in the housing 100, and one end of the balance lever 500 is opposite to the motion module 200, in this case, when the electronic device falls, the motion module 200 will continue to move into the housing 100 due to inertia, and since one end of the balance lever 500 is opposite to the motion module 200, interference will occur with one end of the balance lever 500 in the process that the motion module 200 moves into the housing 100, so that the balance lever 500 has a tendency of rotation, since the balance component is arranged between the housing 100 and the other end of the balance lever 500, the balance component will prevent the balance lever 500 from rotating, thereby ensuring that the balance lever 500 can prevent the motion module 200 from continuing to move into the housing 100, and further avoiding the situation similar to that a user manually presses the motion module 200, the mis-eject of the motion module 200 can be avoided.

The balance member may be of various types, as long as it can perform a balancing function to prevent the balance lever 500 from rotating when interfering with the motion module 200. In a specific embodiment, the balancing assembly may include an elastic tensioning member 700, and the elastic tensioning member 700 is elastically positioned between the housing 100 and the balancing lever 500. The elastic tension member 700 can serve as an elastic support such that an end of the balance lever 500 opposite to the moving module 200 is elastically contacted to the moving module 200, thereby being capable of maintaining interference with the moving module 200.

When the electronic device falls, the inertia of the motion module 200 is large, in order to achieve better balance, in a more preferable scheme, the balance assembly may further include a balance weight 600, the balance weight 600 is connected to the other end of the balance lever 500, and specifically, the balance weight 600 may abut against the other end of the balance lever 500. The elastic tension member 700 is elastically positioned between the housing 100 and the weight 600, thereby achieving the disposition between the housing 100 and the other end of the balance lever 500.

Of course, the balance assembly may include only the balance weight 600, when the electronic device falls, the balance weight 600 and the motion module 200 both have inertia, the inertia of the motion module 200 acts on one end of the balance lever 500, the inertia of the balance weight 600 acts on the other end of the balance lever 500, and the balance weight 600 can also play a role in balancing.

As described above, the structure of the manual operation motion module 200 may be various, and referring to fig. 1 to 16 again, the motion module 200 may include a guide rail 210, and the guide rail 210 may include a first limiting section 211, an extending section 212, a second limiting section 213 and a retracting section 214 connected in sequence in a ring shape. The extending section 212 and the retracting section 214 both play a role of connecting the first limiting section 211 and the second limiting section 213, specifically, one end of the first limiting section 211 opposite to the second limiting section 213 is connected through the extending section 212, and the other end of the first limiting section 211 is connected through the retracting section 214.

On the premise that the motion module 200 has the guide rail 210 with the above structure, the electronic device disclosed in the embodiment of the present invention may further include a first elastic driving element 300 and a limiting mechanism 400.

The first elastic driving member 300 is disposed in the housing 100, and the first elastic driving member 300 drives the motion module 200 to extend out of the housing 100 through the opening 111, so that the motion module is located at the extended position. That is, the direction of the elastic force applied by the first elastic driving member 300 is consistent toward 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 includes 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 guide rail 210, so as to be able to slide to each portion of the guide rail 210 in the moving process 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 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, 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. In the extended position, at least a portion of the limiting portion 410 is located outside the housing 100, the limiting portion 410 cooperates with the first limiting section 211 to limit the movement of the motion module 200 toward the opening 111, and the cooperation between the limiting portion 410 and the first limiting section 211 can maintain the motion module 200 in the extended position. 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 as to maintain the motion module 200 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 waiting shell 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 to the position matched with the first limiting section 211 from the second limiting section 213 through the extending section 212, and at the same time, 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.

As can be seen from the above working process, in the electronic device disclosed in the embodiment of the present invention, the movement module 200 is switched between the extended position and the retracted position by the first elastic driving element 300 and the limiting mechanism 400, and no matter the movement module 200 is controlled to extend out of the housing 100 or retract into the housing 100 through the movement module 200, a user only needs to press the movement module 200, so that the power consumption problem does not exist in the whole operation process, and thus, 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.

On the premise that the limiting portion 410 is a draw hook, the limiting mechanism 400 disclosed in the embodiment of the present invention may further include a mounting bracket 420 and a draw hook bracket 430, the mounting bracket 420 is mounted in the housing 100, the draw hook is connected to the draw hook bracket 430, and the draw hook bracket 430 is rotatably connected to the mounting bracket 420, so that the draw hook is driven by the draw hook bracket 430 to rotate relative to the mounting bracket 420, and the draw hook can better adapt to the guide rail 210.

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 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 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 cling to the 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, at least a portion of the hook may be located in the space covered by the mounting bracket 420, and the hook may be in limit fit with the mounting bracket 420, so that the sliding separation between the hook and the rail 210 can be further avoided under the action of the mounting bracket 420.

Referring to fig. 1 to 12 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 positioned on the moving module 200. In general, 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 is more free.

In an actual assembling process, the first elastic end of the first torsion spring and the second elastic end of the first torsion spring may be in contact with the housing 100 and the motion module 200, respectively. 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 guide rail 210.

In the electronic device disclosed in the embodiment of the present invention, the structure of the guide rail 210 may be various, and in a specific implementation manner, the 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. 4 to 6 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 in the process that the motion module 200 retracts, the user needs to press for a longer time, and because the arc-shaped groove section has a certain curvature, 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 guide rail 210 may have other configurations, and is not limited to a groove-like configuration. Referring to fig. 16, in a specific embodiment, the guide rail 210 may be a convex guide portion, the first position-limiting section 211, the extending section 212, the second position-limiting section 213, and the retracting section 214 are all a plurality of convex sections, the sliding formation of the position-limiting portion 410 may be as shown in fig. 16, and the sliding direction of the position-limiting portion 410 relative to the guide rail 210 is schematically shown by a dotted arrow in fig. 16.

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 section 213 may be a strip-shaped protrusion bent toward the direction away from the motion direction of the motion 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.

The above description is only an example of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art.
