Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, 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 corresponding drawings. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The technical solutions disclosed by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIGS. 1-3 , an embodiment of the present invention discloses a terminal device, which includes a first casing 110 , a second casing 120 , a sliding mechanism, a display screen 140 and an interface 200 . The first casing 110 is slidably connected with the second casing 120 through a sliding mechanism, so the first casing 110 and the second casing 120 can move relative to each other. The display screen 140 is disposed on the first casing 110 , and the interface 200 is disposed on the second casing 120 . Specifically, the interface 200 may include at least one of a charging interface and an earphone interface, and of course, may also include other interfaces. In addition, at least one of a sensor 510 , a receiver 520 , and a camera 530 may also be disposed on the second housing 120 .

As mentioned above, the first housing 110 and the second housing 120 can move relative to each other, and the second housing 120 can be in a sliding-in position and a sliding-out position relative to the first housing 110 when the two are relatively moving. As shown in FIG. 1 , when the second casing 120 is in the sliding position relative to the first casing 110 , the interface 200 is blocked by the first casing 110 . At this time, the interface 200 does not need to play its role, and the first casing 110 shields it. The interface 200 will not affect the normal use of the terminal device, and can also isolate the interface 200 from the external environment. As shown in FIG. 3 , when the second casing 120 is in the sliding-out position relative to the first casing 110 , the interface 200 is exposed to the external environment, and the first casing 110 no longer blocks the interface 200 , so the interface 200 can play its role. When the interface 200 includes a charging interface or an earphone interface, the axis of the insertion opening of the charging interface or the insertion opening of the earphone interface can be parallel to the thickness direction of the mobile terminal, and the charging cable or the earphone cable can be directly inserted into the corresponding interface 200 when the interface 200 is exposed. charging port or headphone jack.

It can be seen that when the interface 200 does not need to work, the interface 200 can be protected by the first housing 110 to prevent the interface 200 from contacting with air, moisture, dust and other media in the external environment for a long time, and at the same time, the interface 200 can be prevented from entering water, so the interface 200 is not easy to be corroded or damaged, the reliability of terminal equipment is improved, and short-circuit problems are not easy to occur, which reduces the safety hazard of terminal equipment. At the same time, the interface 200 is only exposed on the appearance surface of the terminal device during operation, and the interface 200 cannot be seen in other states, so that the appearance and texture of the terminal device are improved, and the user experience is better.

In an optional embodiment, as shown in FIGS. 4-8 , the second casing 120 is provided with a slot 121 , and the interface 200 is movably arranged in the slot 121 . When the second casing 120 is in the sliding-in position relative to the first casing 110 , the interface 200 is retracted into the slot 121 , and when the second casing 120 is in the sliding-out position relative to the first casing 110 , the interface 200 extends beyond slot 121. That is, when the interface 200 moves relative to the second housing 120, it can switch between different states. When the interface 200 extends out of the slot 121 , it is in a working state. Since the interface 200 protrudes relative to the second housing 120 , the interface 200 can be used more conveniently. For example, when the interface 200 is a charging interface, the interface 200 extends out of the slot 121, so that the axis of the insertion port of the charging interface is parallel to the length or width direction of the terminal device, which is more convenient for users to operate.

Further, in order to facilitate the movement of the interface 200 relative to the second casing 120 , the terminal device further includes a driving mechanism connected to the interface 200 , the driving mechanism is arranged in the second casing 120 , and the driving mechanism can apply a force to the interface 200 , and then drive the interface 200 to move relative to the second housing 120 . Under the action of the driving mechanism, the interface 200 is retracted into the slot 121 , so that the second housing 120 can move relative to the first housing 110 and is in the sliding position, when the second housing 120 is relative to the first housing 110 When moving and in the slide-out position, the driving mechanism can drive the interface 200 to extend out of the slot 121, so that the interface 200 is in a working state. The driving mechanism here may include a driving motor, a transmission component, and the like.

In another optional embodiment, the interface 200 is provided with a guide groove 210 , the guide groove 210 has a first limit portion 211 , and the terminal device may further include an elastic member 310 and a limit hook 320 . The elastic member 310 is respectively connected with the interface 200 and the second housing 120 , and can then apply a pop-up force to the interface 200 so that the interface 200 can extend out of the slot 121 . The elastic member 310 can be specifically configured as a spring. One end of the limiting hook 320 is connected to the second housing 120 , and the other end is a free end, which can be matched with the guide groove 210 of the interface 200 .

When the second housing 120 is in the sliding position relative to the first housing 110 , the free end cooperates with the first limiting portion 211 , and the elastic member 310 is elastically deformed at this time. 211 is matched, so the limiting hook 320 can limit the movement of the interface 200 so that it will not pop out of the slot 121 even if it is acted by the elastic member 310 , and the interface 200 is limited in the slot 121 at this time. When the second housing 120 is in the sliding out position relative to the first housing 110, the free end is separated from the first limiting portion 211, so the limiting effect of the limiting hook 320 on the interface 200 disappears, and the interface 200 can be The slot 121 extends out under the action of the elastic member 310 . Such a structure can reliably realize the movement of the interface 200 relative to the second housing 120 , and the interface 200 can be reliably maintained in the retracted state of the slot 121 and the state of the extended slot 121 . In addition, after adopting the elastic member 310 and the limit hook 320, there is no need to set up a complex structure such as a driving motor to realize the driving of the interface 200, but the user can manually press the interface 200. At this time, the elastic member 310 and the limit hook 320 occupy The space is smaller, and the structure of the two is simpler.

The above-mentioned guide groove 210 can be configured as an annular groove, the annular groove has a second limiting portion 212 in addition to the aforementioned first limiting portion 211 . near the bottom of the slot 121 . During the process of retracting the interface 200 into the slot 121 , the free end slides into the first limiting portion 211 from the second limiting portion 212 , so that the second housing 120 can be in a sliding position relative to the first housing 110 . When the second housing 120 is in the sliding-out position relative to the first housing 110 , when the interface 200 extends out of the slot 121 , the free end slides from the first limiting portion 211 into the second limiting portion 212 . At this time, the user can directly manually press the interface 200 to switch between different states, and there is no need to provide additional power elements to control the cooperation state between the limit hook 320 and the interface 200, so that the structure of the terminal device is more Simple. At the same time, the first limiting portion 211 and the second limiting portion 212 can limit the position of the interface 200 relative to the slot 121 , so that the interface 200 is more reliably maintained in the target state.

The solution in which the interface 200 can move relative to the second casing 120 is described above. Of course, the interface 200 can also be immobile relative to the second casing 120, but other structures are used to achieve isolation between the interface 200 and the external environment and The interface 200 is exposed for the purpose of the external environment. Specifically, as shown in FIGS. 9 and 10 , the terminal device may further include a shielding cover 150 , and the shielding cover 150 may cover the surface of the interface 200 . The shielding cover 150 is movably connected with the second casing 120 . Optionally, the shielding cover 150 is movably disposed on the second casing 120 , or the shielding cover 150 is rotatably disposed on the second casing 120 . Of course, the connection form of the shielding cover 150 and the second housing 120 is not limited to this.

After the above connection method is adopted, when the shielding cover 150 covers the surface of the slot 121 , the shielding cover 150 can isolate the interface 200 from the external environment. After the shielding cover 150 moves relative to the second housing 120 , the shielding cover 150 no longer covers the surface of the slot 121 , the slot 121 is exposed to the external environment, and the interface 200 disposed in the slot 121 is naturally exposed to the external environment. . In such an embodiment, the interface 200 does not need to move relative to the second casing 120 , and the movement of the shielding cover 150 relative to the second casing 120 is relatively easy to achieve, so the structure of the terminal device will be simpler, and the life of the interface 200 will be reduced. It will also be longer.

In an optional embodiment, as shown in FIG. 10 , the shielding cover 150 is hinged to the second casing 120 , so that the shielding cover 150 is not substantially worn when moving relative to the second casing 120 , thereby extending the shielding cover 150 The life of the shielding cover 150 is improved at the same time. As shown in FIG. 11 , in an embodiment, in order to drive the shielding cover 150 to move more conveniently, the terminal device may further include a driving source 410, a transmission part connected to the driving source 410, and a rotating shaft 440 connected to the transmission part. The cover 150 is connected with a rotating shaft 440 , and the rotating shaft 440 can drive the shielding cover 150 to rotate. The driving source 410 may be a motor or other structure capable of outputting power, which transmits power to the rotating shaft 440 through the transmission part, thereby making the rotating shaft 440 rotate.

Further, the above-mentioned transmission part may include a first gear 420 and a second gear 430 , the first gear 420 is connected with the output shaft of the driving source 410 , the second gear 430 is meshed with the first gear 420 , and the rotating shaft 440 is connected with the second gear 430 connect. This gear transmission mode has the advantages of accurate transmission, high transmission efficiency, compact structure, reliable operation and long service life.

As shown in FIG. 12 and FIG. 13 , the shielding cover 150 can also slide relative to the second housing 120 . In this case, the terminal device may further include a sliding slot 180 through which the shielding cover 150 can cover the surface of the interface 200 . When the shielding cover 150 slides relative to the sliding slot 180 to the first position, the shielding cover 150 covers the surface of the interface 200 ; when the shielding cover 150 slides relative to the sliding slot 180 to the second position, the shielding cover 150 no longer covers the interface 200 surface, and the interface 200 is exposed to the external environment at this time. When the shielding cover 150 adopts the motion form of sliding, its movement space is smaller, so it is not easy to interfere with other structures.

As shown in FIG. 13 , optionally, the shielding cover 150 is provided with a connecting portion 151 , and the shielding cover 150 is slidably connected to the second housing 120 through the connecting portion 151 , the connecting portion 151 is located in the chute 180 , and the connecting portion 151 The connecting portion 151 can be held in the sliding groove 180 and slide in the sliding groove 180 by cooperating with the sliding groove 180 in a limited position. In order to enable the shielding cover 150 to slide more smoothly relative to the second housing 120 , a linear bearing 160 and a guide bar 170 may be provided in the chute 180 . The linear bearing 160 is located on one side of the connecting portion 151 , and the guide bar 170 is located on the connecting portion. The other side of the 151. Specifically, the linear bearing 160 here may include an inner sleeve and an outer sleeve, balls are provided between the inner sleeve and the outer sleeve, the shielding cover 150 may cooperate with the outer sleeve, and the outer sleeve may be relative to the inner sleeve through the balls The sleeve moves, which in turn reduces friction. The frictional force generated between the linear bearing 160 and the connecting portion 151 , the guide bar 170 and the connecting portion 151 is relatively small, so the user can directly apply a pushing force to the shielding cover 150 to make the shielding cover 150 slide relative to the second housing 120 .

It should be noted that when the interface 200 does not move relative to the second housing 120 , the structure of the interface 200 needs to ensure that the user can make the interface 200 play its role without changing the position of the interface 200 . For example, when the interface 200 is a charging interface, the direction of the axis of the insertion port may be parallel to the thickness direction of the terminal device, so that the user can directly insert the port of the charging cable into the insertion port.

Further, a first guide surface 151 a may be provided on the connecting portion 151 , and a second guide surface 171 may be provided on the guide bar 170 , and the first guide surface 151 a and the second guide surface 171 are abutted. This arrangement can increase the contact area between the connecting portion 151 and the guide bar 170 , so that the wear between the two is less, and thus the service life of the shielding cover 150 and the second housing 120 is prolonged. In addition, the guide bar 170 can be made of a material with a lower friction coefficient, so that the sliding of the shielding cover 150 is smoother. For example, the guide bar 170 can be a plastic bar.

The above-mentioned connecting parts 151 and sliding grooves 180 can be provided in one, two or even more. When there are multiple connecting parts 151 and sliding grooves 180, there are more connection positions between the shielding cover 150 and the second housing 120. The distribution is more uniform, and the shielding cover 150 can be held at the target position more stably.

In an optional embodiment, in order to simplify the operation of the terminal device, when the second casing 120 is in a sliding position relative to the first casing 110, the first casing 110 and the second casing 120 are overlapped. , the interface 200 is shielded by the first casing 110 and further separated from the external environment. When the second casing 120 is in the sliding-out position relative to the first casing 110 , the first casing 110 is displaced relative to the second casing 120 , so that the interface 200 is exposed to the external environment. Optionally, the first housing 110 may be slid and displaced relative to the second housing 120 along the length direction of the terminal device.

A plurality of interfaces 200 may be further arranged, wherein, the plurality of interfaces 200 are all arranged on the second housing 120 . At this time, after the first casing 110 and the second casing 120 slide along the first direction and are misaligned, a part of the interface 200 can be exposed to the external environment; the first casing 110 and the second casing 120 are moved along the second direction ( After sliding and dislocation in a direction opposite to the first direction), another part of the interface 200 can be exposed to the external environment. Of course, in other embodiments, after the first casing 110 and the second casing 120 slide in the same direction and are misaligned, all the interfaces 200 can be exposed to the external environment, which requires the distribution positions of the interfaces 200 to be more compact .

Of course, a part of the interfaces 200 among the above-mentioned multiple interfaces 200 may also be disposed in the first casing 110 , and another part of the interfaces 200 may be disposed in the second casing 120 . When the first housing 110 and the second housing 120 slide in the same direction and are misaligned, the interface 200 provided on the first housing 110 is not blocked by the second housing 120 and is simultaneously provided on the second housing 120 The interface 200 is not blocked by the first housing 110 . In this way, the user can expose all the interfaces 200 in a single operation, so the operation of the terminal device can be simplified in this way.

The terminal device disclosed in the embodiment of the present invention may be a smart phone, a tablet computer, an e-book reader, or a wearable device. Certainly, the terminal device may also be other devices, which are not limited in this embodiment of the present invention.

The above embodiments of the present invention mainly describe the differences between the various embodiments. As long as the different optimization features of the various embodiments are not contradictory, they can be combined to form better embodiments. No longer.
