Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, specifically to an electronic device. Background Technology

[0002] With the development of technology, electronic devices are becoming increasingly widely used. They can be used to capture images and watch videos. Typically, an electronic device includes a first housing, a second housing, a flexible screen, and a motor. The flexible screen is connected to both the first and second housings, and the motor is located within either the first or second housing. The motor moves the first and second housings closer together or further apart, causing the flexible screen to unfold or retract. However, the motor is easily damaged when the electronic device is dropped. Summary of the Invention

[0003] This application provides an electronic device to address the problem in related technologies where the motor is easily damaged when the electronic device is dropped.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] This application provides an electronic device, which includes: a first housing, a second housing, a flexible screen, a rotating component, and a first elastic component;

[0006] The first housing and the second housing are slidably connected, the rotating member is rotatably connected in the first housing, the flexible screen is wrapped around the rotating member, and the first end of the flexible screen is fixedly connected to the second housing, the second end of the flexible screen is connected to the first end of the first elastic member, and the second end of the first elastic member is fixedly connected to the second housing.

[0007] The first housing is provided with a limiting structure, the limiting structure including limiting teeth, and the second housing is provided with a locking structure;

[0008] When the electronic device is in the first state, the locking structure engages with the limiting tooth to limit the position, and the locking structure locks the limiting structure.

[0009] When the electronic device is in the second state, the locking structure separates from the limiting tooth, and the locking structure releases its locking of the limiting structure.

[0010] In this embodiment, by slidably connecting the first and second housings, rotating the member rotatably within the first housing, and arranging the flexible screen around the rotating member, with the first end of the flexible screen fixedly connected to the second housing and the second end of the flexible screen connected to the first end of the first elastic member, which in turn is fixedly connected to the second housing, force can be applied to either the first or second housing to unfold the flexible screen. After unfolding, the electronic device maintains its current state; that is, when the electronic device is in the first state, the locking structure locks the limiting structure. When the electronic device falls, i.e., when the electronic device is in the second state, the locking structure releases the locking of the limiting structure, allowing the first elastic member to quickly retract the flexible screen. The flexible screen, through the rotating member, then quickly moves the second housing closer to the first housing. In this process, a motor is not required to achieve the flexible screen retraction upon a fall, thus avoiding damage to the motor. Furthermore, the rapid retraction of the flexible screen by the first elastic member minimizes the impact on the flexible screen. Attached Figure Description

Figures 1 to 9As shown, the electronic device includes: a first housing 10, a second housing 20, a flexible screen 30, a rotating component 40, and a first elastic component 50.

[0025] The first housing 10 and the second housing 20 are slidably connected. A rotating member 40 is rotatably connected within the first housing 10. A flexible screen 30 is wound around the rotating member 40, with its first end fixedly connected to the second housing 20 and its second end connected to the first end of a first elastic member 50. The second end of the first elastic member 50 is also fixedly connected to the second housing 20. A limiting structure 60 is provided in the first housing 10, including limiting teeth 611. A locking structure 70 is provided in the second housing 20. When the electronic device is in a first state, the locking structure 70 engages with the limiting teeth 611 to limit movement, thus locking the limiting structure. When the electronic device is in a second state, the locking structure separates from the limiting teeth, releasing the locking of the limiting structure.

[0026] In this embodiment of the application, since the first housing 10 and the second housing 20 are slidably connected, the first housing 10 and the second housing 20 can slide relative to each other, so that the first housing 10 and the second housing 20 can move closer to each other or further away from each other. Since the rotating member 40 is rotatably connected to the first housing 10, and the flexible screen 30 is wrapped around the rotating member 40, with the first end of the flexible screen 30 fixedly connected to the second housing 20 and the second end of the flexible screen 30 connected to the first end of the first elastic member 50, and the second end of the first elastic member 50 fixedly connected to the second housing 20, when the first housing 10 and the second housing 20 move away from each other, the first housing 10 drives the rotating member 40 away from the second housing 20, while the second housing 20 drives the first end of the flexible screen 30, so that the flexible screen 30 can move around the rotating member 40, and the second end of the flexible screen 30 applies force to the first elastic member 50, which will stretch the first elastic member 50, thus causing the flexible screen 30 to unfold as the first housing 10 and the second housing 20 move away from each other; when the first housing 10 and the second housing 20 approach each other, the first elastic member 50 contracts, applying force to the second end of the flexible screen 30, and the flexible screen 30 will move around the rotating member 40 and retract. Specifically, when the first housing 10 and the second housing 20 are far apart, the first rotating member 40 drives the flexible screen 30 to move around the rotating member 40, and the first elastic member 50 is stretched by the flexible screen 30 to make the flexible screen 30 unfold, so that the flexible screen 30 is in the unfolded state and the first elastic member 50 is in the stretched state; when the first housing 10 and the second housing 20 are close to each other, the first elastic member 50 drives the flexible screen 30 to move around the rotating member 40, and the first elastic member 50 contracts to make the flexible screen 30 close, so that the flexible screen 30 is in the closed state and the first elastic member 50 returns to its initial state.

[0027] That is, in this embodiment of the application, by making the first housing 10 and the second housing 20 slidably connected, a rotating member 40 is provided in the first housing 10, the flexible screen 30 is wrapped around the rotating member 40, and the first end of the flexible screen 30 is fixedly connected to the second housing 20, the second end of the flexible screen 30 is connected to the first end of the first elastic member 50, and the second end of the first elastic member 50 is fixedly connected to the second housing 20, so that the user can apply force to the first housing 10 and the second housing 20, so that the first housing 10 and the second housing 20 move away from each other, so that the flexible screen 30 unfolds. After the user stops applying force, the first elastic member 50 drives the flexible screen 30 to wrap around the rotating member 40, so that the flexible screen 30 retracts. This avoids the use of components such as the motor 733 to drive the flexible screen 30 to unfold or retract in the electronic device, which can save the power of the electronic device and make the electronic device last longer after charging.

[0028] Additionally, a limiting structure 60, including limiting teeth 611, can be provided in the first housing 10. The second housing 20 is provided with a locking structure 70. Therefore, the locking structure 70 cooperates with the limiting teeth 611, locking the limiting teeth 611, i.e., locking the limiting structure 60; or the locking structure 70 separates from the limiting teeth 611, releasing the locking of the limiting structure 60. Specifically, when the electronic device is in the first state, the locking structure 70 locks the limiting structure 60; when the electronic device is in the second state, the locking structure 70 separates from the limiting teeth 611, releasing the locking of the limiting structure 60.

[0029] The first state can be a state where the first housing and the second housing are relatively stationary, meaning the electronic device maintains its current state. The second state can be a state where the electronic device is in a falling state. When the electronic device maintains its current state, the locking structure 70 locks the limiting structure 60, thus keeping the first housing 10 and the second housing 20 relatively stationary. When the electronic device falls, the locking structure 70 releases the limiting structure 60, allowing the first elastic element 50 to quickly retract the flexible screen 30. The flexible screen 30 then, through the rotating element 40, causes the second housing 20 to quickly approach the first housing 10, bringing them closer together. In this process, the flexible screen 30 can retract when the electronic device falls without the need for a motor, thus avoiding damage to the motor. Simultaneously, the rapid retraction of the flexible screen 30 by the first elastic element 50 also minimizes the impact on the flexible screen 30.

[0030] As described above, in this embodiment, by making the first housing 10 and the second housing 20 slidably connected, the rotating member 40 is rotatably connected to the first housing 10, and the flexible screen 30 is wrapped around the rotating member 40, with the first end of the flexible screen 30 fixedly connected to the second housing 20 and the second end of the flexible screen 30 connected to the first end of the first elastic member 50, and the second end of the first elastic member 50 fixedly connected to the second housing 20, force can be applied to the first housing 10 or the second housing 20 to unfold the flexible screen 30. After the flexible screen 30 unfolds, the electronic device remains in its current state, i.e., when the electronic device is in the first state, the locking structure 70 locks the limiting structure 60. When the electronic device falls, i.e., when the electronic device is in the second state, the locking structure 70 releases the locking of the limiting structure 60, so that the first elastic member 50 can drive the flexible screen 30 to retract quickly. Then, the flexible screen 30, through the rotating member 40, drives the second housing 20 to quickly approach the first housing 10, making the second housing 20 and the first housing 10 close together. In this process, the flexible screen 30 can retract when the electronic device is dropped without the need for a motor, thus avoiding damage to the motor. At the same time, the first elastic element 50 can quickly drive the flexible screen 30 to retract, which also reduces the impact on the flexible screen 30.

[0031] In addition, in this embodiment, the electronic device may also have a third state. When the electronic device is in the third state, the locking structure 70 releases its lock on the limiting structure 60, the first housing 10 and the second housing 20 move relative to each other, causing the locking structure 70 to move relative to the limiting structure 60, so that the locking structure 70 contacts the different limiting teeth 611 on the limiting structure 60. The third state can be a state where the electronic device's state changes, i.e., the first housing 10 and the second housing 20 are closer to each other or further apart.

[0032] When a limiting structure 60 is provided in the first housing 10, and the limiting structure 60 includes limiting teeth 611, and a locking structure 70 is provided in the second housing 20, then by applying force to the first housing 10 and the second housing 20, the first housing 10 and the second housing 20 can be moved away from each other. The first housing 10 can drive the limiting structure 60 to move, so that the limiting structure 60 moves relative to the locking structure 70, so that the locking structure 70 contacts the different limiting teeth 611 on the limiting structure 60. The rotating member 40 in the first housing 10 drives the flexible screen 30 to move as the first housing 10 moves, so that the flexible screen 30 moves around the rotating member 40 and the flexible screen 30 gradually unfolds. Additionally, forces can be applied to the first housing 10 and the second housing 20, causing them to move closer together. This causes the first housing 10 to move the limiting structure 60, which in turn moves relative to the locking structure 70. The locking structure 70 then contacts the different limiting teeth 611 on the limiting structure 60. Simultaneously, the first elastic member 50 applies force to the flexible screen 30, causing it to move around the rotating member 40 and begin to retract. In other words, in the third state, the locking structure 70 contacts the different limiting teeth 611 on the limiting structure 60.

[0033] Furthermore, during the process of applying force to the first housing 10 and the second housing 20 to separate them, if the force is stopped, the first housing 10 and the second housing 20 will stop moving away from each other, and thus the first housing 10 and the second housing 20 will remain relatively stationary. The electronic device will then be in the first state. With the cooperation of the limiting structure 60 and the locking structure 70, the positions of the first housing 10 and the second housing 20 will remain relatively fixed due to the limiting structure 60 and the locking structure 70, thereby maintaining the unfolded state of the flexible screen 30. When force is applied to the first housing 10 and the second housing 20 to bring them closer together, if the force is stopped, the first housing 10 and the second housing 20 will stop approaching each other and remain relatively stationary. The electronic device will then be in the first state. The limiting structure 60 and the locking structure 70 will cooperate to keep the positions of the first housing 10 and the second housing 20 relatively fixed. As a result, the flexible screen 30 will stop moving. That is, the elastic force of the first elastic member 50 is insufficient to drive the flexible screen 30 to move the first housing 10 through the rotating member 40, thereby ensuring that the flexible screen 30 stops moving.

[0034] By setting the limiting structure 60 and the locking structure 70, when force is applied to the first housing 10 and the second housing 20, causing the first housing 10 and the second housing 20 to move away from each other, it is equivalent to the force applied to the first housing 10 and the second housing 20 when the flexible screen 30 is unfolded. This force can overcome the cooperation force of the limiting structure 60 and the locking structure 70. As a result, the first housing 10 can drive the limiting structure 60 to move relative to the locking structure 70, so that the locking structure 70 and the limiting structure 60 cooperate at different positions. That is, the locking structure 70 contacts different limiting teeth 611 on the limiting structure 60. The rotating member 40 in the first housing 10 moves with the movement of the first housing 10. As a result, the rotating member 40 drives the flexible screen 30 to move around the rotating member 40, so that the flexible screen 30 drives the first elastic member 50 to stretch, and the flexible screen 30 is unfolded. When the force applied to the first housing 10 and the second housing 20 is stopped, the limiting structure 60 and the locking structure 70 cooperate to keep the first housing 10 and the second housing 20 relatively stationary, thereby keeping the flexible screen 30 unfolded. Furthermore, during this process, the degree of unfolding of the flexible screen 30 can be determined according to actual needs; that is, after the flexible screen 30 is partially unfolded, the force applied to the first housing 10 and the second housing 20 is stopped, and the flexible screen 30 will stop unfolding.

[0035] Subsequently, when force is applied to the first housing 10 and the second housing 20, causing them to move closer together, which is equivalent to the flexible screen 30 retracting, the force applied to the first housing 10 and the second housing 20 can overcome the cooperating force of the limiting structure 60 and the locking structure 70. Thus, the first housing 10 can drive the limiting structure 60 to move relative to the locking structure 70, allowing the locking structure 70 and the limiting structure 60 to engage at different positions. When the force applied to the first housing 10 and the second housing 20 stops, the limiting structure 60 and the locking structure 70 engage, keeping the first housing 10 and the second housing 20 relatively stationary. During this process, the first elastic member 50 continuously applies force to the flexible screen 30, causing the flexible screen 30 to move around the rotating member 40 and begin to retract. During this process, as needed, after the flexible screen 30 is retracted to a certain extent, the force applied to the first housing 10 and the second housing 20 can be stopped. The first housing 10 and the second housing 20 will then remain relatively stationary due to the cooperation of the limiting structure 60 and the locking structure 70, thus keeping the flexible screen 30 in its current state. In other words, during the use of the electronic device, the user can apply different forces to the first housing 10 and the second housing 20 as needed to unfold the flexible screen 30. During the unfolding process, the user can stop applying force to the first housing 10 and the second housing 20 at any time, thus keeping the flexible screen 30 in its current state. That is, the flexible screen 30 can be suspended at any time. Of course, the user can also apply force to the first housing 10 and the second housing 20 to switch the flexible screen 30 from unfolded to retracted. During this process, the user can also stop applying force to the first housing 10 and the second housing 20 at any time, thus keeping the flexible screen 30 in its current state, thereby improving the user experience of using the electronic device.

[0036] In addition, in this embodiment of the application, the first housing 10 and the second housing 20 can be slidably connected by: a groove is provided on the second housing 20, and a portion of the first housing 10 is embedded in the groove, so that the first housing 10 and the second housing 20 are slidably connected. When the first housing 10 and the second housing 20 slide relative to each other, the first housing 10 slides along the groove, so that the first housing 10 and the second housing 20 can move away from each other or move closer to each other.

[0037] Of course, the sliding connection between the first housing 10 and the second housing 20 can also be achieved in other ways. For example, a sliding track can be provided on the second housing 20, and a sliding platform can be provided on the first housing 10, with the sliding platform embedded in the sliding track, thereby enabling the first housing 10 and the second housing 20 to be slidably connected. The specific method of sliding connection between the first housing 10 and the second housing 20 is not limited in this embodiment.

[0038] In addition, in the embodiments of this application, the first elastic element 50 can be a spring. Of course, the first elastic element 50 can also be other elastic devices, such as a spring sheet. The specific type of the first elastic element 50 is not limited in the embodiments of this application.

[0039] In some embodiments, the limiting structure 60 may include a first sliding member 61, on which a plurality of limiting teeth 611 are provided. The plurality of limiting teeth 611 are distributed along the sliding direction of the first housing 10. The locking structure 70 includes a locking tooth 71. When the electronic device is in a first state, the locking tooth 71 engages with the limiting tooth 611, and the locking tooth 71 locks the limiting tooth 611. When the electronic device is in a second state, the locking tooth 71 disengages from the limiting tooth 611, and the locking tooth 71 releases its lock on the limiting tooth 611.

[0040] Since the first sliding member 61 is provided with multiple limiting teeth 611, and the multiple limiting teeth 611 are distributed along the sliding direction of the first housing 10, and the locking structure 70 includes locking teeth 71, when force is applied to the first housing 10 and the second housing 20, causing the first housing 10 and the second housing 20 to move away from each other and the flexible screen 30 to unfold, i.e. when the electronic device is in the third state, the first housing 10 will drive the first sliding member 61 to move. As a result, the multiple limiting teeth 611 on the first sliding member 61 move with the movement of the first sliding member 61, and the multiple limiting teeth 611 will move relative to the locking teeth 71, so that the locking teeth 71 move from the gap between two adjacent limiting teeth 611 to another gap, i.e., the locking teeth 71 are located between different limiting teeth 611, and thus contact different limiting teeth 611. When force is stopped applied to the first housing 10 and the second housing 20, the first housing 10 and the second housing 20 remain relatively stationary. That is, when the electronic device is in the first state, the locking tooth 71 is located between two adjacent limiting teeth 611, so the locking tooth 71 blocks the limiting tooth 611, making the limiting tooth 611 stationary relative to the locking tooth 71. Thus, the first housing 10 and the second housing 20 remain relatively stationary, allowing the flexible screen 30 to maintain its current unfolded state. Furthermore, force can be applied to the first housing 10 and the second housing 20 as needed. After the flexible screen 30 unfolds to a certain extent, the force is stopped, and the flexible screen 30 remains stationary due to the action of the locking tooth 71 and the limiting tooth 611, thus maintaining the current state of the electronic device. When the electronic device falls, that is, when the electronic device is in the second state, the locking tooth 71 separates from the limiting tooth 611, and the locking tooth 71 releases its lock on the limiting tooth 611. As a result, the first elastic element 50 drives the flexible screen 30 to retract, providing protection for the flexible screen 30.

[0041] Similarly, when force is applied to the first housing 10 and the second housing 20, causing the first housing 10 and the second housing 20 to move closer to each other and the flexible screen 30 to retract, i.e. when the electronic device is in the third state, the first housing 10 will drive the first sliding member 61 to move. As a result, the multiple limiting teeth 611 on the first sliding member 61 will move with the movement of the first sliding member 61. The multiple limiting teeth 611 will then move relative to the locking teeth 71, causing the locking teeth 71 to move from the gap between two adjacent limiting teeth 611 to another gap. That is, the locking teeth 71 are located between different limiting teeth 611, thus contacting different limiting teeth 611. When force is stopped applied to the first housing 10 and the second housing 20, the first housing 10 and the second housing 20 remain relatively stationary. That is, when the electronic device is in the first state, the locking tooth 71 is located between two adjacent limiting teeth 611, so the locking tooth 71 blocks the limiting tooth 611, making the limiting tooth 611 stationary relative to the locking tooth 71. Thus, the first housing 10 and the second housing 20 remain relatively stationary, allowing the electronic device 30 to maintain its current state. Furthermore, force can be applied to the first housing 10 and the second housing 20 as needed. After the flexible screen 30 retracts to a certain extent, the force is stopped, and the flexible screen 30 remains stationary due to the action of the locking tooth 71 and the limiting tooth 611, thus maintaining its current state. When the electronic device falls, that is, when the electronic device is in the second state, the locking tooth 71 separates from the limiting tooth 611, and the locking tooth 71 releases its lock on the limiting tooth 611. As a result, the first elastic element 50 drives the flexible screen 30 to retract, providing protection for the flexible screen 30.

[0042] In addition, when the user applies force to the first housing 10 and the second housing 20 to make the first housing 10 move away from each other or move closer to each other, the force applied by the user needs to overcome the movement of the locking tooth 71 from the gap between adjacent limiting teeth 611 to another gap. The movement of the locking tooth 71 from the gap between adjacent limiting teeth 611 to another gap will make the electronic device damped, so that the user will have a damping sensation, which can improve the user experience.

[0043] It should be noted that, in this embodiment, the limiting tooth 611 may have a first inclined surface, and the locking tooth 71 may have a second inclined surface. When the locking tooth 71 is located between two adjacent limiting teeth 611, the first inclined surface may contact the second inclined surface, thereby facilitating the locking tooth 71 to disengage from between two adjacent limiting teeth 611 and enter another gap when force is applied to the first housing 10 and the second housing 20. Furthermore, the tips of both the limiting tooth 611 and the locking tooth 71 may be arc-shaped, thereby facilitating the locking tooth 71 to disengage from between two adjacent limiting teeth 611 and enter another gap.

[0044] It should also be noted that, in the embodiments of this application, multiple limiting teeth 611 can be directly chiseled on the first sliding member 61, that is, multiple limiting teeth 611 are opened on the first sliding member 61, so that the first sliding member 61 has multiple limiting teeth 611.

[0045] It is understood that in some embodiments, when the electronic device is in the second state, the first housing and the second housing may also be in a state of relative movement, either unfolded or retracted, and the locking structure and the limiting tooth remain separated at all times. During the unfolding or retracting of the electronic device in the second state, the user cannot experience any damping sensation when opening or closing the electronic device.

[0046] In addition, in some embodiments, a slide rail 21 may be fixedly connected to the second housing 20. The extension direction of the slide rail 21 is the same as the sliding direction of the first housing 10. A sliding boss is provided on the first sliding member 61, and the sliding boss is embedded in the slide rail 21.

[0047] When a slide rail 21 is fixedly connected to the second housing 20, and a sliding boss is provided on the first sliding member 61, with the sliding boss embedded in the slide rail 21, when force is applied to the first housing 10 and the second housing 20, causing the first housing 10 to move closer to or further away from the second housing 20, the first housing 10 drives the first sliding member 61 to move, and the sliding boss slides in the slide rail 21. Thus, the slide rail 21 can guide the sliding boss, meaning the sliding boss can only slide along the slide rail 21, thereby preventing the first sliding member 61 from wobbling during movement. In other words, by fixing the slide rail 21 to the second housing 20 and embedding the sliding boss on the first sliding member 61 in the slide rail 21, the problem of the first sliding member 61 wobbling during the movement of the first housing 10 can be prevented.

[0048] In some embodiments, the limiting structure 60 may include a second sliding member 62, on which a rack 621 is connected. The rack 621 has a plurality of limiting teeth 611 and extends along the sliding direction of the first housing 10. The locking structure 70 includes a locking tooth 71. When the electronic device is in a first state, the locking tooth 71 engages with the limiting tooth 611, locking the limiting tooth 611. When the electronic device is in a second state, the locking tooth 71 disengages from the limiting tooth 611, releasing the locking of the limiting tooth 611.

[0049] Since the second sliding member 62 is connected to a rack 621, which has multiple limiting teeth 611 and extends along the sliding direction of the first housing 10, and the locking structure 70 includes locking teeth 71, when force is applied to the first housing 10 and the second housing 20, causing the first housing 10 and the second housing 20 to move away from each other and the flexible screen 30 to unfold, i.e., when the electronic device is in the third state, the first housing 10 will drive the second sliding member 62 to move. As a result, the rack 621 on the second sliding member 62 moves with the movement of the second sliding member 62, and the rack 621 will move relative to the locking teeth 71, so that the locking teeth 71 mesh with different positions of the rack 621, i.e., the locking teeth 71 contact different limiting teeth 611 on the rack 621. When force is stopped applied to the first housing 10 and the second housing 20, the first housing 10 and the second housing 20 remain relatively stationary. That is, when the electronic device is in the first state, the locking tooth 71 is located between two adjacent limiting teeth 611 on the rack 621. Therefore, the locking tooth 71 blocks the rack 621, keeping the rack 621 stationary relative to the locking tooth 71. This keeps the first housing 10 and the second housing 20 relatively stationary, allowing the electronic device to maintain its current unfolded state. Furthermore, force can be applied to the first housing 10 and the second housing 20 as needed. After the flexible screen 30 unfolds to a certain extent, the force is stopped, and the flexible screen 30 remains stationary due to the action of the locking tooth 71 and the rack 621, thus maintaining its current state. When the electronic device falls, that is, when the electronic device is in the second state, the locking tooth 71 separates from the limiting tooth 611, releasing the locking tooth 71 from the limiting tooth 611. This allows the first elastic element 50 to cause the flexible screen 30 to retract, providing protection for the flexible screen 30.

[0050] Similarly, when force is applied to the first housing 10 and the second housing 20, causing them to move closer together and the flexible screen 30 to retract (i.e., when the electronic device is in the third state), the first housing 10 will drive the second sliding member 62 to move. Consequently, the rack 621 on the second sliding member 62 moves along with the second sliding member 62, and the rack 621 moves relative to the locking tooth 71. This causes the locking tooth 71 to engage with different positions on the rack 621, i.e., the locking tooth 71 contacts different limiting teeth 611 on the rack 621. When force is stopped applied to the first housing 10 and the second housing 20, the first housing 10 and the second housing 20 remain relatively stationary. That is, when the electronic device is in the first state, the locking tooth 71 is located between two adjacent limiting teeth 611 on the rack 621. Therefore, the locking tooth 71 blocks the rack 621, keeping the rack 621 stationary relative to the locking tooth 71. Thus, the first housing 10 and the second housing 20 remain relatively stationary, allowing the electronic device to maintain its current state. Furthermore, force can be applied to the first housing 10 and the second housing 20 as needed. After the flexible screen 30 retracts to a certain extent, the force is stopped, and the flexible screen 30 remains stationary due to the action of the locking tooth 71 and the limiting tooth 611, thus maintaining its current state. When the electronic device falls, i.e., when the electronic device is in the second state, the locking tooth 71 separates from the limiting tooth 611, and the locking tooth 71 releases its lock on the limiting tooth 611. As a result, the first elastic element 50 drives the flexible screen 30 to retract, thus protecting the flexible screen 30.

[0051] In addition, when the user applies force to the first housing 10 and the second housing 20 to make the first housing 10 move away from each other or move closer to each other, the force applied by the user needs to overcome the meshing force between the locking tooth 71 and the rack 621. This meshing force will make the electronic device damped, so that the user will have a damping feeling, which can improve the user experience.

[0052] It should be noted that the rack 621 can be bonded to the second sliding member 62 by adhesive bonding, or welded to the second sliding member 62 by welding. Of course, the rack 621 can also be fixed to the second sliding member 62 by fasteners, such as bolts or pins. This embodiment of the application does not limit the specific method used.

[0053] Alternatively, a sliding boss can be provided on the second sliding member 62, and a slide rail 21 is fixedly connected in the second housing 20, with the sliding boss embedded in the slide rail 21.

[0054] In some embodiments, the locking structure 70 may further include a telescopic structure connected to the second housing 20, with the locking tooth 71 connected to the telescopic structure. When the electronic device is in a first state, the telescopic structure drives the locking tooth 71 to move along a first direction, causing the locking tooth 71 to engage with the limiting tooth 611, thus locking the limiting tooth 611. When the electronic device is in a second state, the telescopic structure drives the locking tooth 71 to move along a second direction, causing the locking tooth 71 to separate from the limiting tooth 611, thus releasing the locking tooth 71 from locking the limiting tooth 611. The first direction and the second direction are opposite.

[0055] Since the telescopic structure is connected to the second housing 20, and the locking tooth 71 is connected to the telescopic structure, the telescopic structure can drive the locking tooth 71 to move, allowing the electronic device to lock or release the locking tooth 611 in different states. Specifically, when the electronic device is in the first state, the telescopic structure drives the locking tooth 71 to move in the first direction, so that the locking tooth 71 engages with the limiting tooth 611, locking the limiting tooth 611; when the electronic device is in the second state, the telescopic structure drives the locking tooth 71 to move in the second direction, so that the locking tooth 71 separates from the limiting tooth 611, releasing the locking tooth 71 from the limiting tooth 611. In other words, by providing the telescopic structure, it is convenient for the locking tooth 71 to lock or release the limiting tooth 611.

[0056] In some embodiments, the locking structure 70 may also include a fixing member 72, which is fixed in the second housing 20. The fixing member 72 is provided with a mounting hole 721 and a receiving cavity 722. The telescopic structure is at least partially located in the receiving cavity 722. The locking tooth 71 is installed in the mounting hole 721, and the telescopic structure drives the locking tooth 71 to move along the axial direction of the mounting hole 721.

[0057] Since the fixing member 72 is fixed in the second housing 20, and the fixing member 72 is provided with a mounting hole 721 and a receiving cavity 722, the telescopic structure is at least partially located in the receiving cavity 722. The locking tooth 71 is installed in the mounting hole 721 and is movable along the axial direction of the mounting hole 721. Therefore, when the locking tooth 71 is located between two adjacent limiting teeth 611, if the first housing 10 and the second housing 20 are far apart or close to each other, i.e., the electronic device is in the third state, the first housing 10 drives the first sliding member 61 to move, so that the multiple limiting teeth 611 can move with the movement of the first sliding member 61. The locking tooth 71 is then subjected to the force of the limiting tooth 611, causing the telescopic structure to move the locking tooth 71 along the second direction. The locking tooth 71 disengages from the gap between two adjacent limiting teeth 611, allowing the limiting tooth 611 to move. When the first housing 10 and the second housing 20 stop moving, i.e., when they remain relatively stationary and the electronic device is in the first state, the telescopic structure moves the locking tooth 71 along the first direction, causing it to enter the gap between two adjacent limiting teeth 611. The locking tooth 71 acts as a barrier against the limiting tooth 611, allowing the first housing 10 and the second housing 20 to remain relatively stationary. When the electronic device is in a drop state, i.e., in the second state, the telescopic structure moves the locking tooth 71 along the second direction, releasing the locking tooth 71 from the limiting tooth 611. In addition, since the locking tooth 71 is installed in the mounting hole 721, the mounting hole 721 can also guide the locking tooth 71 during its movement, making it less likely to wobble when the locking tooth 71 moves.

[0058] In addition, in this embodiment, the locking tooth 71 can also be directly fixed in the second housing 20. In this case, the locking tooth 71 can be elastic, so that when the rack 621 or the limiting tooth 611 moves, the locking tooth 71 can deform, so that the locking tooth 71 meshes with different positions of the rack 621, or the locking tooth 71 meshes with different limiting teeth 611.

[0059] Additionally, in some embodiments, the telescopic structure includes a drive member 73, which is at least partially located in the receiving cavity. The drive member 73 is connected to a locking tooth 71, and the drive member 73 drives the locking tooth 71 to move in a first direction or in a second direction.

[0060] Since the driving member 73 is connected to the locking tooth 71, the driving member 73 can drive the locking tooth 71 to move along the axial direction of the mounting hole 721. Specifically, when the first housing 10 and the second housing 20 are moving away from or close to each other, i.e., when the electronic device is in the third state, the first housing 10 drives the first sliding member 61 to move, so that multiple limiting teeth 611 can move with the movement of the first sliding member 61. Thus, the locking tooth 71 will be subjected to the force of the limiting teeth 611, so that the locking tooth 71 can move along the second direction. At the same time, the driving member 73 drives the locking tooth 71 to move along the second direction, and the locking tooth 71 disengages from the gap between two adjacent limiting teeth 611, so that the limiting tooth 611 can move. When the first housing 10 and the second housing 20 stop moving, the first housing 10 and the second housing 20 remain relatively stationary, i.e., when the electronic device is in the first state, the driving member 73 can drive the locking tooth 71 to move along the first direction, so that the locking tooth 71 enters the gap between two adjacent limiting teeth 611. The locking tooth 71 can block the limiting teeth 611, so that the first housing 10 and the second housing 20 can remain relatively stationary. That is, by setting the driving component 73, the locking tooth 71 can move along the axial direction of the mounting hole 721. When the electronic device is in a drop state, that is, when the electronic device is in the second state, the telescopic structure drives the locking tooth 71 to move along the second direction, thereby releasing the locking tooth 71 from locking the limiting tooth 611.

[0061] In some embodiments, the locking tooth 71 can be a metal tooth, and the driving member 73 includes an electromagnetic member 731 and a second elastic member 732. The electromagnetic member 731 is fixed in the receiving cavity 722, one end of the second elastic member 732 is connected to the electromagnetic member 731, and the other end of the second elastic member 732 is connected to the locking tooth 71. When the electromagnetic member 731 is energized, the locking tooth 71 moves along the second direction, compresses the second elastic member 732, and moves closer to the electromagnetic member 731. When the electromagnetic member 731 is de-energized, the second elastic member 732 drives the locking tooth 71 to move along the first direction, so that the locking tooth 71 is reset.

[0062] Since the locking tooth 71 is a metal tooth, the electromagnetic component 731 is fixed in the receiving cavity 722, one end of the second elastic component 732 is connected to the electromagnetic component 731, and the other end of the second elastic component 732 is connected to the locking tooth 71. Therefore, when the first housing 10 and the second housing 20 are moving away from or close to each other, that is, when the electronic device is in the third state, the first housing 10 drives the first sliding component 61 to move, and the first sliding component 61 drives multiple limiting teeth 611 to move. As a result, the limiting teeth 611 exert force on the locking tooth 71, and the locking tooth 71 moves along the first... The two-way movement causes the locking tooth 71 to compress the second elastic element 732, causing the locking tooth 71 to disengage from the gap between the two adjacent limiting teeth 611. During the movement of the limiting teeth 611, the limiting teeth 611 continue to contact the locking tooth 71 and exert force on the locking tooth 71. However, when the limiting teeth 611 move and the locking tooth 71 realigns with the gap between the two adjacent limiting teeth 611, the second elastic element 732 exerts force on the locking tooth 71, causing the locking tooth 71 to re-enter the gap between the adjacent limiting teeth 611. That is, when the first housing 10 and the second housing 20 move away from each other or move closer to each other, the limiting tooth 611 applies force to the locking tooth 71, the locking tooth 71 applies force to the second elastic member 732, and the second elastic member 732 applies force to the locking tooth 71. In other words, the force applied by the user to the first housing 10 and the second housing 20 needs to overcome the force of the second elastic member 732 and also needs to overcome the force of the locking tooth 71 and the force of the locking tooth 71 moving relative to the limiting tooth 611 when there is a gap between different limiting teeth 611, so that the user generates a damping feeling and improves the user experience.

[0063] Furthermore, when the first housing 10 and the second housing 20 are moving away from or close to each other, during the movement of the first housing 10, the electromagnetic component 731 can be energized intermittently. That is, when the first housing 10 moves to a preset distance, which can be the width of a limiting tooth 611, the electromagnetic component 731 can be energized, thereby generating a magnetic force. The electromagnetic component 731 can then attract the metal locking component, causing the locking tooth 71 to move along the second direction. The locking tooth 71 compresses the second elastic component 732, thereby disengaging the locking tooth 71 from the gap between two adjacent limiting teeth 611. Afterwards, the power supply to the battery component can be stopped, that is, the electromagnetic component 731 is de-energized. The locking tooth 71 will then be reset under the action of the second elastic component 732, that is, the second elastic component 732 drives the locking tooth 71 to move along the first direction. The locking tooth 71 re-enters the gap between another two adjacent limiting teeth 611, blocking the limiting tooth 611.

[0064] In addition, in this embodiment, the second elastic element 732 can be a spring. Of course, the second elastic element 732 can also be other elastic devices, such as a spring sheet. The specific type of the second elastic element 732 is not limited in this embodiment. Furthermore, in this embodiment, the electromagnetic element 731 can be an electromagnet.

[0065] In some embodiments, the locking tooth 71 can be connected to the limiting boss 711, and the wall of the mounting hole 721 is provided with a limiting groove 7211. The limiting boss 711 is embedded in the limiting groove 7211. The limiting groove 7211 extends along the axial direction of the mounting hole 721, and the size of the limiting groove 7211 is larger than the size of the limiting boss 711, so that the limiting boss 711 can move in the limiting groove 7211.

[0066] Since the limiting boss 711 connected to the locking tooth 71 is embedded in the limiting groove 7211 on the wall of the mounting hole 721, and the size of the limiting groove 7211 is larger than the size of the limiting boss 711, the limiting boss 711 can move in the limiting groove 7211. Thus, when the locking tooth 71 moves along the axial direction of the mounting hole 721, the locking tooth 71 drives the limiting boss 711 to move, so the locking tooth 71 has a certain amount of room to move. At the same time, the limiting groove 7211 also plays a limiting role for the limiting boss 711. That is, when the limiting boss 711 abuts against the groove wall of the limiting groove 7211, the limiting groove 7211 limits the limiting boss 711. Thus, the groove wall of the limiting groove 7211 can block the limiting boss 711, thereby limiting the locking tooth 71 and preventing the limiting tooth 711 from disengaging from the mounting hole 721 under the action of the second elastic member 732. That is, by connecting the limiting boss 711 to the locking tooth 71 and setting the limiting groove 7211 on the hole wall of the mounting hole 721, the limiting boss 711 is embedded in the limiting groove 7211, which can prevent the locking tooth 71 from disengaging from the mounting hole 721 under the action of the second elastic member 732.

[0067] In some embodiments, the driving component 73 can be a motor 733. The output shaft of the motor 733 is connected to a lead screw 734. A slider 735 is provided on the lead screw 734. The slider 735 is connected to the locking tooth 71. The motor 733 is used to drive the lead screw 734 to rotate so that the slider moves along the lead screw 734, thereby driving the locking tooth 71 to move in a first direction or a second direction.

[0068] Since the output shaft of the motor 733 is connected to the lead screw 734, and the lead screw 734 is equipped with a slider 735, which is connected to the locking tooth 71, when the motor 733 is running, the output shaft of the motor 733 drives the lead screw 734 to rotate, and the slider 735 moves along the axial direction of the lead screw 734, that is, the rotational motion of the lead screw 734 is converted into the linear motion of the slider 735. After the slider 735 moves, it can drive the locking tooth 71 to move, so that the locking tooth 71 moves along the axial direction of the mounting hole 721. When the limiting structure 60 includes a first sliding member 61, and the first sliding member 61 is equipped with multiple limiting teeth 611, when the locking tooth 71 moves along the first direction, the locking tooth 71 can be located between two adjacent limiting teeth 611, thereby blocking the limiting teeth 611. The locking tooth 71 can also disengage from between two adjacent limiting teeth 611, thereby releasing the obstruction of the limiting teeth 611. Similarly, when the limiting structure 60 includes a second sliding member 62 and the second sliding member 62 is connected to a rack 621, when the locking tooth 71 moves in the first direction, the locking tooth 71 can be located between two adjacent teeth on the rack 621, that is, the locking tooth 71 engages with the rack 621, so that the locking tooth 71 can block the movement of the rack 621. The locking tooth 71 can also disengage between two adjacent teeth on the rack 621, that is, the locking tooth 71 no longer engages with the rack 621, thereby releasing the obstruction of the rack 621.

[0069] Furthermore, when the user applies force to the first housing 10 and the second housing 20, causing the flexible screen 30 to unfold or retract, the motor 733 can drive the slider 735 to move along the second direction, causing the slider 735 to drive the locking tooth 71 to move along the second direction, so that the locking tooth 71 no longer obstructs the limiting tooth 611 or the rack 621. When the flexible screen 30 unfolds to a certain extent, the motor 733 can drive the slider 735 to move along the first direction, causing the slider 735 to drive the locking tooth 71 to move along the first direction, so that the locking tooth 71 moves between two adjacent limiting teeth 611, or engages with the rack 621, blocking the limiting tooth 611 or the rack 621. Control buttons can be provided on the first housing 10 or the second housing 20. The control buttons are electrically connected to the motor 733. When the user applies force to the first housing 10 and the second housing 20 to make the flexible screen 30 unfold or retract, the user can press the control button to send a command to the motor 733, so that the motor 733 drives the slider 735 to move, and the slider 735 drives the locking tooth 71 to move.

[0070] In addition, in this embodiment, the slider 735 and the locking tooth 71 can be connected by a connecting rod 736, that is, one end of the connecting rod 736 is connected to the slider 735, and the other end of the connecting rod 736 is connected to the locking tooth 71.

[0071] It should be noted that, in the embodiments of this application, the motor 733 can be a servo motor or a stepper motor. The specific type of motor 733 is not limited in this embodiment.

[0072] In some embodiments, a sensor 80 may be provided in the first housing 10 and / or the second housing 20, and a controller may be provided in the first housing 10 and / or the second housing 20. The sensor 80 is electrically connected to the controller, and the controller is electrically connected to the drive unit 73. The sensor 80 is used to detect the acceleration information of the electronic device when it falls, and sends the acceleration information to the controller. The controller is used to control the drive unit 73 to move the locking tooth 71 according to the acceleration information, so that the locking tooth 71 moves along the second direction, the locking tooth 71 separates from the limiting tooth 611, the locking tooth 71 releases the limiting of the flexible screen 30, and the flexible screen 30 retracts.

[0073] Since sensor 80 is electrically connected to controller, and controller is electrically connected to drive component 73, and sensor 80 detects the acceleration information of electronic device during drop, sensor 80 can send the detected acceleration information to controller. Controller can then control drive component 73 based on the acceleration information, causing drive component 73 to move locking tooth 71. This causes locking tooth 71 to move along the second direction and disengage from the gap between two adjacent limiting teeth 611, i.e., locking tooth 71 separates from limiting teeth 611. Thus, locking tooth 71 releases its lock on limiting teeth 611, and first elastic element 50 can then move the second end of flexible screen 30. That is, first elastic element 50 applies force to flexible screen 30, and flexible screen 30 applies force to rotating component 40, causing rotating component 40 to move first housing 10, bringing first housing 10 and second housing 20 closer together. Flexible screen 30 retracts, preventing significant damage to flexible screen 30 when electronic device is unfolded and dropped. That is, by setting up a sensor 80 and a controller, the sensor 80 detects the acceleration information when the electronic device falls, and the controller controls the drive component 73 according to the acceleration information, so that the drive component 73 drives the locking tooth 71 to move in the second direction. The locking tooth 71 releases the obstruction of the limiting tooth 611, which is equivalent to releasing the limitation on the flexible screen 30. Thus, the flexible screen 30 can quickly close under the action of the first elastic component 50, avoiding the problem of the electronic device falling and causing great damage to the flexible screen 30 when the electronic device is unfolded.

[0074] It should be noted that the sensor 80 can be disposed in the first housing 10, the second housing 20, or both the first housing 10 and the second housing 20. This embodiment of the application does not limit the specific embodiment to this method. Furthermore, in this embodiment, the sensor 80 can be an acceleration sensor.

[0075] In some embodiments, the locking tooth 71 can be a metal tooth. The driving member 73 includes an electromagnetic member 731 and a second elastic member 732. The electromagnetic member 731 is fixed in the receiving cavity 722. One end of the second elastic member 732 is connected to the electromagnetic member 731, and the other end of the second elastic member 732 is connected to the locking tooth 71. The controller is electrically connected to the electromagnetic member 731. The controller is used to control the electromagnetic member 731 to be energized according to the acceleration information, so that the electromagnetic member 731 drives the locking tooth 71 to move along the second direction. The locking tooth 71 separates from the limiting tooth 611, and the locking tooth 71 releases its limitation on the flexible screen 30, causing the flexible screen 30 to retract.

[0076] Since the locking tooth 71 is a metal tooth, the driving component 73 includes an electromagnetic component 731 and a second elastic component 732. The electromagnetic component 731 is fixed in the receiving cavity 722. One end of the second elastic component 732 is connected to the electromagnetic component 731, and the other end of the second elastic component 732 is connected to the locking tooth 71. The controller is electrically connected to the electromagnetic component 731. Therefore, during the fall of the electronic device, the sensor 80 can send the detected acceleration information to the controller. The controller controls the electromagnetic component 731 to be energized according to the acceleration information. After being energized, the electromagnetic component 731 generates magnetic force, which can attract the metal locking tooth 71, causing the locking tooth 71 to move along the second direction. The locking tooth 71 will then disengage from the gap between two adjacent limiting teeth 611, that is, the locking tooth 71 separates from the limiting teeth 611. The locking tooth 71 then releases its obstruction of the limiting teeth 611, so that the first elastic component 50 can drive the flexible screen 30 to quickly retract.

[0077] In addition, in this embodiment, when the driving component 73 is a motor 733, the controller can be electrically connected to the motor 733. During the fall of the electronic device, the sensor 80 can send the detected acceleration information to the controller. The controller controls the driving component 73 according to the acceleration information, so that the driving component 73 drives the lead screw 734 to rotate, thereby the slider 735 moves along the second direction. The slider 735 drives the locking tooth 71 to move along the second direction. The locking tooth 71 disengages from the gap between two adjacent limiting teeth 611, and the locking tooth 71 releases its obstruction to the limiting tooth 611. The first elastic member 50 can then drive the flexible screen 30 to quickly retract.

[0078] In addition, in this embodiment of the application, the controller can be a control chip, which can be integrated on a circuit board.

[0079] It should be noted that, in the embodiments of this application, electronic devices include, but are not limited to, mobile phones, tablets, laptops, handheld computers, vehicle terminals, wearable devices, and pedometers.

[0080] In this embodiment, by slidingly connecting the first housing 10 and the second housing 20, rotating member 40 is rotatably connected within the first housing 10, and flexible screen 30 is wound around rotating member 40. The first end of flexible screen 30 is fixedly connected to the second housing 20, and the second end of flexible screen 30 is connected to the first end of first elastic member 50, which is also fixedly connected to the second housing 20. This allows force to be applied to either the first housing 10 or the second housing 20, causing flexible screen 30 to unfold. After unfolding, the electronic device maintains its current state; that is, when the electronic device is in the first state, locking structure 70 locks limiting structure 60. When the electronic device falls, i.e., when the electronic device is in the second state, locking structure 70 releases the locking of limiting structure 60, allowing first elastic member 50 to quickly retract flexible screen 30. Subsequently, flexible screen 30, through rotating member 40, causes second housing 20 to quickly approach first housing 10, bringing them closer together. In this process, the flexible screen 30 can retract when the electronic device is dropped without the need for a motor, thus avoiding damage to the motor. At the same time, the first elastic element 50 can quickly drive the flexible screen 30 to retract, which also reduces the impact on the flexible screen 30.

[0081] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
