Technical Field

The present invention relates to a terminal device.

Background

As functions of terminal devices (such as mobile phones and tablet computers) are increased, functional devices configured on the terminal devices are increased, and as demands of users on appearance of the terminal devices are increased, users prefer terminal devices with large screen occupation ratio.

In order to increase the screen occupation ratio of the terminal equipment, the terminal equipment in the related art adopts a motor to drive the telescopic module to move, so that the telescopic module can extend and retract relative to the shell of the terminal equipment. The telescopic module occupies less display area, so that the screen occupation ratio of the terminal equipment is higher.

However, the motor may cause the cost of the terminal device to be high, and the motor drive needs to be configured with a relatively complex transmission mechanism to realize the drive of the telescopic module, which undoubtedly may cause the structure of the terminal device to be relatively complex.

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.

As shown in fig. 1 to 7, an embodiment of the present invention discloses a terminal device, which includes a housing 300, a telescopic module 100, an elastic driving element 201, and a limiting assembly.

The housing 300 is provided with an opening 310, and specifically, the housing 300 has a frame, and the opening 310 may be provided at the top of the frame. The opening 310 allows the expansion module 100 to move in and out of the housing 300, thereby extending and retracting the expansion module 100.

The expansion module 100 is movably disposed in the housing 300, and further enters and exits the housing 300 through the opening 310. When the telescopic module 100 is extended out relative to the housing 300, the corresponding function can be realized; when the retractable module 100 is retracted with respect to the housing 300, it is accommodated in the housing 300. The telescopic module 100 does not occupy the display area of the terminal device, so the screen occupation ratio of the terminal device is large. The retractable module 100 is provided with a guide rail 110, and the guide rail 110 has a first position-limiting portion 111. In an embodiment of the present invention, the retractable module 100 may include at least one of a camera, a sensor, a fingerprint identification module, a receiver, and a fill-in light.

The elastic actuator 201 is elastic and is disposed in the housing 300. This elastic driving member 201 can lean on or link together with flexible module 100, and when flexible module 100 pressurized and when retracting in casing 300, flexible module 100 pressed or tensile elastic driving member 201 for elastic driving member 201 takes place to warp, and elastic driving member 201 can exert the reaction force to flexible module 100, and the pop-up force promptly, under the effect of this pop-up force, elastic driving member 201 can drive flexible module 100 and stretch out casing 300. In order to provide a more stable ejection force, the elastic driving member 201 may be configured as a second spring, and the terminal device may further include a guide rod 250 connected to the telescopic module 100, wherein the elastic driving member 201 is sleeved outside the guide rod 250, and one end of the elastic driving member is connected to or abutted against the guide rod 250, and the other end of the elastic driving member is connected to or abutted against the telescopic module 100.

The position limiting assembly is disposed in the housing 300, and may include a position limiting member 202 and a position limiting driving member 203. The stop 202 is slidable along the rail 110 between a stop position and a release position. The limit driver 203 can drive the limit stop 202. When the telescopic module 100 needs to be kept in the retracted state, the position limiting member 202 is located at the position limiting position, and at this time, the position limiting member 202 is matched with the first position limiting portion 111 on the telescopic module 100, so that an acting force can be applied to the telescopic module 100 to overcome the ejection force applied to the telescopic module 100 by the elastic driving member 201, and the purpose of limiting the movement of the telescopic module 100 is achieved, so that the telescopic module 100 cannot be ejected. When the telescopic module 100 needs to extend out of the housing 300, the limiting member 202 is in the release position, and at this time, the limiting member 202 can be separated from the first limiting portion 111 on the telescopic module 100, so as to release the cooperation between the limiting member 202 and the first limiting portion 111, so as to remove the limiting effect of the limiting member 202 on the telescopic module 100, thereby releasing the telescopic module 100 to allow the telescopic module 100 to move, and allowing the telescopic module 100 to pop up.

Alternatively, the position-limiting driving member 203 may include a magnetic driving portion 230, and the magnetic driving portion 230 may be specifically an electromagnetic structure, and the magnetic state of the magnetic driving portion is different when the magnetic driving portion is powered on and powered off, so that the position-limiting member 202 may be driven to move by magnetic action. Specifically, the magnetic driving portion 230 may only drive the limiting member 202 to move from the limiting position to the releasing position, may only drive the limiting member 202 to move from the releasing position to the limiting position, and may also simultaneously realize that the limiting member 202 moves from the limiting position to the releasing position and from the releasing position to the limiting position. In contrast, when the magnetic driving part 230 simultaneously realizes that the limiting member 202 moves from the limiting position to the releasing position and from the releasing position to the limiting position, the energy consumption of the terminal device is high, and therefore, in the embodiment of the present invention, the limiting driving member 203 includes the magnetic driving part 230 and the elastic driving part 240. Wherein: the elastic driving portion 240 drives the limiting member 202 to move from the releasing position to the limiting position, and the magnetic driving portion 230 drives the limiting member 202 to move from the limiting position to the releasing position; alternatively, the elastic driving portion 240 drives the limiting member 202 to move from the limiting position to the releasing position, and the magnetic driving portion 230 drives the limiting member 202 to move from the releasing position to the limiting position. The magnetic driving unit 230 may be connected to the stopper 202, or may be kept at a predetermined distance as long as it can apply a magnetic force to the stopper 202.

As can be seen from the above, when the telescopic module 100 is in the retracted state, the limiting member 202 is in the limiting position, and at this time, the limiting member 202 is in limiting fit with the first limiting portion 111 of the telescopic module 100, and the elastic driving member 201 applies the ejection force to the telescopic module 100 due to the deformation, but the ejection force does not work due to the limitation of the limiting member 202, and the telescopic module 100 cannot move. If the telescopic module 100 needs to work, the limit driving member 203 applies a driving force to the limit member 202, so that the limit member 202 slides along the guide rail 110 to be separated from the first limit portion 111 of the telescopic module 100, and finally reaches the release position. At this time, the limit of the limiting member 202 on the expansion module 100 is removed, and the ejecting force applied by the elastic driving member 201 to the expansion module 100 will act, so that the expansion module 100 moves out of the housing 300.

After the telescopic module 100 is used, the user can press the telescopic module 100, the telescopic module 100 is moved into the housing 300 by the pressing force applied by the user, the position-limiting member 202 can slide from the releasing position to the position-limiting position under the action of the position-limiting driving member 203, and at this time, the telescopic module 100 returns to the retracted state described above. So reciprocal, just can move and make flexible module 100 switch between operating condition and unoperated state through flexible module 100, flexible module 100 does not occupy the area in display area, and then improves terminal equipment's screen and accounts for the ratio.

In the embodiment of the present invention, the telescopic movement of the telescopic module 100 does not require a motor and a transmission mechanism with a complicated structure, so the terminal device disclosed in the embodiment of the present invention can solve the problems of high cost and complicated structure existing in the prior art that the motor is adopted to drive the telescopic module 100 to extend and retract.

In order to make the position-limiting driving member 203 reliably apply a force to the position-limiting member 202, the position-limiting member 202 in the embodiment of the present invention may include a second position-limiting portion 210 and a connecting portion 220. The second position-limiting portion 210 is engaged with the guide rail 110 to slide along the guide rail 110, one end of the connecting portion 220 is connected to the second position-limiting portion 210, and the connecting portion 220 is respectively connected to the magnetic driving portion 230 and the elastic driving portion 240. With such a structure, the magnetic driving portion 230 and the elastic driving portion 240 can drive the second position-limiting portion 210 to slide along the guide rail 110 through the connecting portion 220, which is not only convenient for the magnetic driving portion 230 to reliably apply an acting force to the position-limiting member 202, but also convenient for the arrangement of components in the terminal device.

In a further embodiment, in order to facilitate the magnetic driving part 230 and the elastic driving part 240 to drive the second position-limiting part 210 to move through the connecting part 220, the connecting part 220 may include a connecting rod 221 and a first end rod 222 and a second end rod 223 connected to both ends of the connecting rod 221. Alternatively, the first end bar 222 and the second end bar 223 may be connected to the same side of the connecting rod 221 to facilitate the arrangement of the spacing assembly. The first end rod 222 is connected to the magnetic driving part 230, the second end rod 223 is connected to the second stopper 210, and the connecting rod 221 is connected to the elastic driving part 240.

There are various options for the connection between the second position-limiting part 210 and the second end rod 223, for example, the second position-limiting part 210 can be directly fixed on the surface of the second end rod 223 facing the guide rail 110. However, since the height of the second position-limiting portion 210 may vary during the sliding process of the second position-limiting portion 210 along the guide rail 110, in order to adapt to the height variation, the second end rod 223 may be directly configured as a rod having elasticity, but this weakens the structural strength of the second end rod 223, and affects the effective transmission of the acting force. Based on this, the embodiment of the present invention movably connects the second position-limiting part 210 to the second end rod 223, so as to allow the height of the second position-limiting part 210 to change when moving along the guide rail 110. Meanwhile, the second end rod 223 is provided with a positioning hole 223a, and the second position-limiting portion 210 may be a position-limiting column, and one end of the position-limiting column is fitted in the positioning hole 223 a.

Further, the second end rod 223 may be provided with an elastic member 224, and one end of the elastic member 224 may be pressed against the stopper post. Because the elastic member 224 has elasticity, when the restraining column slides along the guide rail 110, the elastic member 224 can prevent the restraining column from being disengaged from the second end rod 223, thereby driving the restraining column to be engaged with the guide rail 110. Alternatively, the elastic member 224 may be a spring sheet, so that the elastic member 224 has better elasticity.

A side of the second end rod 223 facing away from the first stopper portion 111 may be flush with a surface of the connecting rod 221, but in order to improve the connection strength of the stopper post with the second end rod 223, a protruding surface 223b may be provided on a side of the second end rod 223 facing away from the first stopper portion 111, the protruding surface 223b protrudes in a direction away from the first stopper portion 111 with respect to the connecting rod 221, and is opposite to the elastic member 224, and a portion of the elastic member 224 may be pressed against at least a portion of the protruding surface 223 b. With the convex surface 223b, the dimension of the second end bar 223 in the thickness direction of the terminal device is larger, and the structural strength of the second end bar 223 is increased, thereby achieving the aforementioned object.

In an alternative embodiment, the elastic member 224 may include a first planar section 224a, a transition section 224b and a second planar section 224c connected in series. The first plane section 224a is fixed to the connection rod 221, so that a large contact area can be formed therebetween, so that the connection strength of the elastic member 224 and the connection rod 221 is increased. The second plane section 224c is pressed on the limiting column, and the second plane section 224c protrudes relative to the first plane section 224a in the direction away from the first limiting portion 111, and at this time, the structure of the whole elastic member 224 and the structure of the protruding surface 223b of the second end rod 223 have consistency, so that the elastic member 224 is prevented from being excessively deformed after being mounted on the connecting rod 221, and the friction force between the limiting column and the guide rail 110 can be prevented from being excessively large, so that the relative movement between the limiting column and the guide rail 110 is smoother.

In order to more reliably drive the connection part 220, the elastic driving part 240 may be provided as a first spring having one end connected to the housing 300 and the other end connected to the connection rod 221. Specifically, the connection rod 221 may be provided with a hook portion 225, and one end of the elastic driving portion 240 is hung on the hook portion 225.

In the embodiment of the present invention, the guide rail 110 plays a role of guiding. The guide rail 110 may be a protrusion protruding from the surface of the expansion module 100, or may be a guide groove. In order to improve the stability of sliding, the guide rail 110 is preferably a guide groove. Further, the guide groove may include a stopper groove section 112, an extension guide groove section 113, and a retraction guide groove section 114. Wherein, spacing groove section 112 extends along the direction of movement of perpendicular to flexible module 100, stretches out the one end intercommunication of guide way section 113 and spacing groove section 112, and withdrawal guide way section 114 communicates with the other end of spacing groove section 112, and stretches out guide way section 113 and withdrawal guide way section 114 intercommunication. With this structure, the first position-limiting portion 111 can be a position-limiting boss formed on the position-limiting groove section 112. In the process of retracting the telescopic module 100 into the housing 300, the position-limiting member 202 slides into the position-limiting groove section 112 from the retracting guide groove section 114 and is engaged with the first position-limiting portion 111; when the telescopic module 100 extends out of the housing 300, the limiting member 202 is separated from the first limiting portion 111 and slides into the extending guide groove section 113 from the limiting groove section 112.

Considering that the first position-limiting portion 111 is lower than other portions of the guide groove, the guide groove is formed in an uneven structure as a whole in order to make the position-limiting member 202 slide more smoothly in the guide groove. Specifically, the limiting boss is smoothly connected to the retracting guide groove section 114, the limiting boss is connected to the limiting groove section 112 through a limiting plane 115, the limiting plane 115 is perpendicular to the moving direction of the telescopic module 100, and at the limiting position, the limiting plane 115 is in limiting fit with the limiting member 202. With this structure, the acting force between the limiting plane 115 and the limiting member 202 can maximally form the acting force for limiting the telescopic module 100, so that the telescopic module 100 is more reliably maintained in the retracted state.

The terminal device disclosed by the embodiment of the invention can be a smart phone, a notebook computer, a tablet computer, an e-book reader or a wearable device. Of course, the terminal device may also be other devices, and the embodiment of the present invention is not limited thereto.

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.
