An electronic device according to an embodiment of the present application is described below with reference to fig. 1 to 6.

As shown in fig. 1, an electronic device 10 according to some embodiments of the present application includes a first housing 100, a second housing 102, a flexible screen 130, and a damping mechanism 140.

Specifically, the second housing 102 is slidably connected with the first housing 100. The flexible screen 130 is connected to the second housing 102. The flexible screen 130 is rolled or expanded as the second housing 102 slides. The damping mechanism 140 includes a cylinder 142 and a piston 144, the piston 144 being movably disposed within the cylinder 142. The cylinder 142 and the piston 144 enclose a damping chamber 152, and the damping chamber 152 is used for accommodating damping medium. The cylinder 142 is connected to the first housing 100, and the piston 144 is connected to the second housing 102.

According to the electronic device 10 of the embodiment of the application, by providing the damping mechanism 140, the cylinder 142 and the piston 144 of the damping mechanism 140 are respectively connected with the first casing 100 and the second casing 102, so that when the electronic device 10 is impacted, the impact on the first casing 100 and the second casing 102 can be reduced by the vibration reduction function of the damping mechanism 140, and further the impact on the flexible screen 130 is reduced, so as to form protection on the flexible screen 130. When the driving mechanism is arranged, the driving mechanism can be protected.

Specifically, the cylinder 142 of the damping mechanism 140 is connected to the first housing 100, the piston 144 of the damping mechanism 140 is connected to the second housing 102, and the second housing 102 and the first housing 100 of the electronic device 10 have a larger outer contour than the flexible screen 130, that is, when the electronic device 10 is impacted, the second housing 102 or the first housing 100 is often impacted first, and then the impact is transmitted to the flexible screen 130 from the second housing 102 or the first housing 100. By providing the damping mechanism 140, no matter the second housing 102 is impacted first or the first housing 100 is impacted first, at least a part of the impact force can be absorbed by the damping mechanism 140 through vibration reduction, so that the impact force is reduced or blocked from further transmitting to the flexible screen 130, and the flexible screen 130 is protected.

The flexible screen 130 is coupled to the second housing 102 such that the flexible screen 130 moves with the second housing 102 as the second housing 102 slides relative to the first housing 100. Thus, when the second housing 102 and the first housing 100 are moved away from each other, the flexible screen 130 may be unfolded to improve the user's visibility. When the second housing 102 and the first housing 100 are close to each other, the flexible screen 130 can be rolled to be folded, so that the space occupied by the flexible screen 130 is reduced.

The damping mechanism 140 includes a cylinder 142 and a piston 144, and the cylinder 142 and the piston 144 enclose a damping chamber 152, and the damping chamber 152 is used for accommodating a damping medium. That is, the damping mechanism 140 may perform a damping function, such as an air damper, by the cooperation of the damping medium with the cylinder 142 and the piston 144. As shown in fig. 6, the damping mechanism 140 will be described below by taking an air damper as an example.

The air damper type damping mechanism 140 includes a cylinder 142 and a piston 144. The cylinder 142 is coupled to the first housing 100. The piston 144 is connected to the second housing 102. The piston 144 is movably disposed in the cylinder 142, and the piston 144 and the cylinder 142 enclose a damping chamber 152. The bottom of the cylinder 142 is provided with an air hole 150 communicating with a damper chamber 152.

As shown in fig. 5, when the piston 144 moves toward the bottom of the cylinder 142, air in the damping chamber 152 is compressed and moves outward through the air hole 150, and since the area of the air hole 150 relative to the cylinder 142 is much smaller, the air cannot be rapidly discharged outward, so that an opposite resistance is generated to the piston 144 to delay the movement of the piston 144. Meanwhile, as the air is discharged through the air hole 150, the air in the damping chamber 152 does not completely block the movement of the piston 144, and thus, as the air is discharged, the kinetic energy of the piston 144 is gradually absorbed, thereby achieving the purpose of vibration reduction. When the electronic apparatus 10 is subjected to a sudden impact, for example, a drop occurs, an impact force generated by the impact of the electronic apparatus 10 with the ground or an object first acts on the second housing 102 or the first housing 100, and is transferred to the damping mechanism 140. The impact force pushes the piston 144 to move, and is transferred to the air in the damping chamber 152, and is absorbed by the gradually discharged air, so as to achieve the effect of vibration reduction, and play a role of buffering for the flexible screen 130, so that the impact force can not act on the flexible screen 130 any more.

An air damper is used as the damping mechanism 140, which is simple in structure and easy to install. In addition, as the damping mechanism 140 provided in the electronic device 10, the damping medium of the air damper is air, which is light in weight and easy for a user to take and place. More importantly, air is used as a damping medium, and therefore, the fluid is cleaner than other fluids, and even if leakage occurs, the electronic device 10 is not polluted. In addition, since air is used as a medium, a special flow path does not need to be provided, the structure is very simple, the number of components can be reduced, and the weight of the electronic device 10 can be further reduced. In addition, air is used as a damping medium, the requirement on the sealing performance of the damping cavity 152 is low, the problem of medium leakage does not need to be considered, the structure is simplified, and the processing precision is reduced.

The air hole 150 is formed at the bottom of the cylinder 142, so that the air hole 150 can be always communicated with the damping chamber 152 during the movement of the piston 144, thereby ensuring the smooth exhaust.

It is understood that the number of the air holes 150 may be one or more. By setting the number of the air holes 150, the exhaust speed can be flexibly set, so that the movement speed of the piston 144 can be set, and different damping effects or vibration reduction effects can be set according to factors such as the specific size and weight of the electronic device 10.

It will be appreciated that the air holes 150 are not limited to being disposed in the bottom of the cylinder 142. In some embodiments, the air vent 150 is disposed on the piston 144.

In other embodiments, the number of the air holes 150 is plural, for example, one air hole 150 is provided at each of the bottom of the cylinder 142 and the piston 144.

In still other embodiments, the air holes 150 are disposed on the sidewall of the cylinder 142.

In addition to the air holes 150, a gap may be provided between the piston 144 and the cylinder 142. For example, neither the cylinder 142 nor the piston 144 is provided with the air hole 150. The diameter of the piston 144 is smaller than the inner diameter of the cylinder 142, so that the piston 144 has a certain clearance with the sidewall of the cylinder 142 after entering the cylinder 142. As the piston 144 moves toward the bottom of the cylinder 142, air within the damper chamber 152 is expelled from the gap therebetween. The piston 144 moves away from the bottom of the cylinder 142 and air enters the damper chamber 152 from the gap between the two. The gap may be uniformly or non-uniformly arranged.

The piston 144 is not necessarily provided in a circular shape. The piston 144 may be provided in an elliptical shape. The elliptical shape of the piston 144 has a major axis that is equal to the inner diameter of the cylinder 142, such that a gap is formed between the cylinder 142 and the major axis of the piston 144, thereby allowing air to pass into and out of the damper chamber 152.

According to other embodiments of the present application, there is provided an electronic device 10 wherein the damping mechanism 140 further comprises an adjustment device. The adjusting device is disposed at the air hole 150, and the adjusting device is used for adjusting the size of the air hole 150.

By setting the adjusting device to adjust the size of the air hole 150, the moving speed of the piston 144 can be flexibly adjusted, thereby changing the vibration damping effect of the damping mechanism 140.

The adjusting device can be a rotatable or slidable sheet, and the adjusting device can cover different areas of the air hole 150 by rotating different angles or sliding different distances, so that the ventilation area of the air hole 150 is correspondingly changed, the size of the air hole 150 is adjusted, and the vibration damping effect of the damping mechanism 140 is changed.

Or the number of the air holes 150 is plural. The adjusting device covers different numbers of air holes 150 by rotating or sliding, thereby realizing the purpose of adjusting the ventilation area of the air holes 150 and further changing the damping effect of the damping mechanism 140.

In any of the above embodiments, damping mechanism 140 further comprises a piston rod 146. The piston rod 146 is connected to the piston 144, and the piston 144 is connected to the second housing 102 via the piston rod 146. The cylinder 142 is coupled to the first housing 100. In contrast, the cylinder 142 has a larger volume and a heavier weight than the piston rod 146, so that the cylinder 142 is connected to the first housing 100, and the piston rod 146 is connected to the second housing 102, which is beneficial to improving the stability of the installation and fixation of the cylinder 142 and reducing the stress on the second housing 102.

It will be appreciated that in other embodiments, the piston rod 146 may be coupled to the first housing 100 and the cylinder 142 disposed on the second housing 102, as the case may be.

In the above embodiment, the damping mechanism 140 further includes a cover plate 148. Cover plate 148 fits over piston rod 146. As the piston rod 146 moves, the cover plate 148 is correspondingly moved toward or away from the cylinder 142, so that when approaching the cylinder 142, the cylinder 142 can be closed to prevent the entry of foreign substances. Or when the cylinder 142 is far away, the cylinder 142 is opened, so that the inside of the cylinder 142 can be cleaned and tidied conveniently.

In electronic device 10 according to other embodiments of the present application, damping mechanism 140 is present in plurality. The plurality of damper mechanisms 140 are provided at intervals.

By arranging the plurality of damping mechanisms 140 and arranging the plurality of damping mechanisms 140 at intervals, the protection strength of the damping mechanisms 140 on the electronic device 10 and the flexible screen 130 is improved. Specifically, the plurality of damping mechanisms 140 are provided at intervals, so that the damping mechanisms 140 are provided at different positions of the electronic apparatus 10. When the electronic device 10 is subjected to external impact, the damping mechanisms 140 are distributed at different positions, so that the damping mechanisms 140 can bear the impact earlier, and the damping mechanisms 140 absorb the impact energy, thereby reducing the transmission of the impact force on the electronic device 10 and improving the vibration reduction effect of the damping mechanisms 140.

Alternatively, the damping mechanisms 140 are provided in two. The electronic device 10 is provided with a damping mechanism 140 at each end. Since the electronic device 10 often has a greater influence on the components when an impact is applied to the end portion, the damping mechanism 140 is disposed at the end portion, which is beneficial to improving the vibration damping effect.

In any of the above embodiments, the electronic device 10 further comprises a drive mechanism. The driving mechanism is connected to the first casing 100 and the second casing 102, and the driving mechanism is used for driving the second casing 102 and the first casing 100 to move relatively.

By providing a driving mechanism, automation of the relative sliding of the second housing 102 and the first housing 100 is facilitated, and the relative movement of the two is not required to be manually pushed by a user. Therefore, the stability and the reliability of the sliding between the two can be ensured, and the burden of a user is lightened. In addition, the damping mechanism 140 is provided, so that the driving mechanism is protected.

Specifically, the drive mechanism includes: motor 112, screw 116, first nut 118, and second nut 120. The first nut 118 is bolted to the threaded rod 116, and the second nut 120 is fixedly connected to the threaded rod 116 in the axial direction. The first nut 118 is coupled to the first housing 100 and the second nut 120 is coupled to the second housing 102. The screw 116 is also connected to the motor 112, and the motor 112 is used to drive the screw 116 to rotate.

The screw 116 is rotated relative to the first nut 118 by the motor 112. Since the screw 116 is bolted to the first nut 118, and the first nut 118 is coupled to the first housing 100, the first nut 118 is not rotated easily, so that the screw 116 moves in its axial direction and brings the second nut 120 fixedly coupled thereto in its axial direction together, so that the second nut 120 comes close to or away from the first nut 118. Further, the first nut 118 is coupled to the first housing 100, and the second nut 120 is coupled to the second housing 102, so that as the first nut 118 and the second nut 120 approach or move away from each other, the second housing 102 and the first housing 100 correspondingly approach or move away from each other, thereby achieving the rolling or unfolding of the flexible screen 130.

The driving mechanism adopts a structure of a screw rod 116 and a nut, namely a screw rod structure, and has the advantages of small number of parts, simple structure and easy assembly. The screw structure can convert the rotation motion into a linear motion, so as to push the relative sliding between the second housing 102 and the first housing 100, thereby achieving the purpose of expanding the flexible screen 130. In addition, the screw rod structure is adopted, the process of converting rotation into linear motion is stable, and the stability of the expansion of the flexible screen 130 is favorably improved, so that the protection effect on the flexible screen 130 is improved, and the damage caused by severe shaking of the flexible screen 130 during expansion or curling is favorably avoided.

It will be appreciated that rotation of the motor 112 in one direction causes the first nut 118 and the second nut 120 to move toward one another, while rotation of the motor 112 in the opposite direction causes the first nut 118 and the second nut 120 to move away from one another.

In other embodiments, the first nut 118 and the threaded rod 116 are fixedly coupled in the axial direction, while the second nut 120 is bolted to the threaded rod 116. When the motor 112 drives the screw 116, the screw 116 rotates relative to the second nut 120, and drives the first nut 118 to move away from or close to the second nut 120.

Further, the drive mechanism also includes a speed reduction structure 114. One end of the speed reducing structure 114 is connected to the screw 116, and the other end of the speed reducing structure 114 is connected to the motor 112. The torque of the motor 112 is transmitted to the screw 116 through the speed reducing structure 114, which is beneficial to reduce the rotation speed of the screw 116, increase the torque, and thus increase the smoothness of the rotation of the screw 116, and increase the traction force on the first casing 100 or the second casing 102.

Specifically, the reduction structure 114 includes a case and a reduction gear assembly. The reduction gear assembly is arranged in the box body. The reduction structure 114 comprises a reduction gear assembly, which is simple in construction, technically mature, and easy to assemble and produce. The reduction gear assembly is arranged in the box body, so that the reduction gear assembly is conveniently separated from external impurities through the box body, and therefore the impurities are prevented from entering the reduction gear assembly to influence the operation of the reduction gear assembly. The reduction gear assembly can be prevented from being touched by a user to cause injury through the box body.

According to other embodiments of the present application, the driving mechanism of the electronic device 10 is not limited to the screw structure of the screw 116+ the nut, and may include at least one of the following or a combination thereof: gear structure, belt structure, sprocket structure.

It is understood that the electronic device 10 provided according to the embodiment of the present application may be any one of a mobile phone, a tablet computer, a game machine, and an electronic book.

The electronic device 10 according to an embodiment of the present application is illustrated by taking a mobile phone as an example. The sliding mechanism of the scroll screen and the flexible screen 130 are protected by buffering through an air chamber on the mobile phone, namely, a structural scheme that an air damper is used as a damping mechanism 140.

The piston rod 146 with the piston 144 at the head is connected to the second housing 102 of the electronic device 10, when the second housing 102 moves, the piston rod 146 drives the piston 144 to move in the cylinder 142 of the damping mechanism 140, and the cylinder 142 is connected to the first housing 100 of the mobile phone. Meanwhile, a small air hole 150 is reserved at the bottom of the cylinder 142, when the second shell 102 of the mobile phone is impacted, air in the cylinder 142 cannot be exhausted quickly due to sudden stress because the air hole 150 is small, and air damping is formed in the cylinder 142 to prevent a driving mechanism of a scroll screen or the flexible screen 130 from being damaged.

As shown in fig. 3, the motor 112 drives the screw 116 through the reduction gear assembly, the second housing 102 is provided with a second nut 120, and the first housing 100 of the mobile phone is provided with a first nut 118. The screw 116 is connected to one of the first nut 118 and the second nut 120 by a screw drive to slide the second housing 102, thereby rolling and expanding the flexible screen 130. The structure of the set is a main realization mechanism for realizing the extension and expansion of the screen by the scroll screen.

As shown in fig. 2, when the flexible screen 130 is in the expanded state, the second housing 102 is in the open state, and the flexible screen 130 is kept in the open state by using the screw 116 as a support, at this time, if the mobile phone falls down carelessly and is hit, the acting force acts directly on the screw 116 and the casing of the deceleration structure 114 through the second housing 102, which may easily cause damage to the entire driving mechanism.

As shown in fig. 3, in order to prevent the driving mechanism or the flexible screen from impacting the scroll screen in the falling process, the same air dampers are respectively assembled at the upper end and the lower end of the mobile phone in the present embodiment, and when the mobile phone falls and is impacted, the air dampers at the two ends bear the impact.

Specifically, as shown in fig. 4 and 5, the cylinder 142, the piston 144, the piston rod 146, and the cover plate 148 constitute a set of air dampers as the damping mechanism 140. The piston rod 146 is connected to the second housing 102 and the cylinder 142 is connected to the first housing 100 of the handpiece. The piston 144 is assembled to the head of the piston rod 146, and during the extension and contraction process of the mobile phone, the piston 144 moves slowly in the inner space of the cylinder 142 along with the piston rod 146, and the piston 144 and the inner part of the cylinder 142 are in a sealed state, so that a relatively closed damping chamber 152 is formed. The piston 144 forces air in the damper chamber 152 to flow out through the air hole 150 so as not to interfere with the movement of the second housing 102. When the mobile phone falls, the mobile phone is impacted, and the gas cannot flow out quickly through the air hole 150 in a short time, so that a certain pressure is formed in the damping cavity 152 to achieve a buffering effect.

The air damper mechanism of operation is described with reference to figure 5. The air outlet speed is adjusted by controlling the size of the open pore of the air hole 150, thereby achieving the effect of adjusting the buffer.

The beneficial effects of this embodiment are: electronic device 10 fall protection can be provided.

Other configurations of the electronic device 10, such as the housing, the structure of the flexible screen 130, the type of motor 112, etc., and the operation thereof, according to embodiments of the present application are known to those of ordinary skill in the art and will not be described in detail herein.
