Description

Technical Field

[0001] This invention relates to the field of computer technology, and more specifically to an electronic device. Background Technology

[0002] Laptops, compared to tablets, have more powerful processors and more memory, making them suitable for running complex software and games. Current laptops typically consist of a first unit and a second unit that rotate and connect. The first unit is the main unit, usually including the keyboard, touchpad, and most of the laptop's internal hardware, such as the processor, memory, and hard drive. The second unit is the display, which houses the screen. Currently, the first and second units of a laptop can only rotate relative to each other to a folded or open state, which cannot meet the needs of more diverse usage scenarios. Based on these issues, a new type of electronic device is needed to provide a new way for laptops to open and close, making them suitable for a wider range of applications. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention provides an electronic device to provide a new mode of opening and closing a laptop computer.

[0004] To achieve the above and other related objectives, the present invention provides an electronic device comprising: a first unit and a second unit. The first unit has a receiving cavity; the second unit is slidably inserted into the receiving cavity and electrically or wirelessly connected to the first unit. One of the second unit and the first unit is provided with a display screen, and the other with a keyboard input device. When the second unit slides to a first position away from the receiving cavity, the second unit is rotatably connected to the first unit, and the display screen and the keyboard input device can rotate towards each other to an angle. When the second unit rotates to the first position, the rotatable connection between the second unit and the first unit can be released, and the second unit can be slidably inserted into the receiving cavity.

[0005] In one embodiment of the present invention, the first unit or the second unit provided with the keyboard input device includes a touch screen, and the keyboard input device is a touch keyboard displayed on the touch screen.

[0006] In one embodiment of the present invention, when the keyboard input device is disposed in the first unit and the second unit is inserted into the receiving cavity, the electronic device can switch to a tablet mode for operation and display via the touch screen; when the first unit and the second unit are in the angled state, the touch keyboard is turned on, and the electronic device can switch to a laptop mode for operation via the touch screen and display via the display screen.

[0007] In one embodiment of the present invention, the keyboard input device is disposed in the second unit, the display screen is disposed in the first unit, the display screen is a touch screen, and when the second unit is inserted into the receiving cavity, the electronic device can switch to a tablet mode for operation and display via the touch screen.

[0008] In one embodiment of the present invention, an ejection device is provided between the first unit and the second unit for ejecting the second unit from the receiving cavity to expose at least part of it.

[0009] In one embodiment of the present invention, the ejection device includes a trigger, a compression mechanism, and at least one elastic element. The receiving cavity includes a cavity wall opposite to the insertion direction of the second unit. One end of the elastic element is mounted on the cavity wall, and the other end of the elastic element points towards the second unit. The compression mechanism is installed in the receiving cavity and compresses the other end of the elastic element to keep the elastic element in a compressed state. The trigger is movably mounted on the first unit and is configured to trigger the compression mechanism to release the other end of the elastic element, so that the elastic element pushes the second unit at least partially exposed from the receiving cavity during the recovery deformation process.

[0010] In one embodiment of the present invention, the compression mechanism includes a first connecting rod, a second connecting rod, and a first hook portion. The first connecting rod is rotatably mounted in the receiving cavity. The first hook portion is connected to the side of the first connecting rod near the second unit, and the second connecting rod is connected to the side of the first connecting rod away from the first hook portion. The triggering element includes a trigger body and a resetting element. The trigger body is located on the side of the second connecting rod away from the first connecting rod and slides through the wall of the receiving cavity. One end of the trigger body extending into the receiving cavity is fixedly connected to the second connecting rod to trigger the first hook portion to release the elastic element. The resetting element is disposed in the receiving cavity to reset the trigger body after triggering.

[0011] In one embodiment of the present invention, a second hook portion is fixedly connected to one end of the elastic member near the second unit. When the second unit squeezes the second hook portion to a set position, the first hook portion connects to the second hook portion and locks the elastic member in a compressed state. When the triggering member triggers the second connecting rod, the second hook portion disengages from the first hook portion, the elastic member recovers its deformation, and pushes the second unit away.

[0012] In one embodiment of the present invention, the second unit is provided with a second hook portion. When the second unit slides to the second position, the second hook portion is connected to the first hook portion, and the second unit compresses the elastic element. When the trigger body triggers the second connecting rod, the second hook portion disengages from the first hook portion, the elastic element recovers its deformation, and pushes the second unit away.

[0013] In one embodiment of the present invention, the ejection device includes two elastic elements, and the compression mechanism further includes a connecting rod fixing seat. The connecting rod fixing seat is fixedly installed in the receiving cavity. The two elastic elements are arranged side by side between the second unit and the cavity wall, and are respectively located on both sides of the connecting rod fixing seat. The first connecting rod is rotatably installed on the connecting rod fixing seat, and the first hook portion is connected to the position corresponding to the two elastic elements respectively.

[0014] In one embodiment of the present invention, the reset member includes a reset spring, which is located on the side of the second link away from the trigger body and the compression direction is consistent with the sliding direction of the trigger body. One end of the reset spring is fixed to the wall of the receiving cavity, and the other end of the reset spring is fixed to the second link or the trigger body.

[0015] In one embodiment of the present invention, the electronic device further includes an elastic cord disposed in the receiving cavity, one end of the elastic cord being connected to the wall of the receiving cavity, and the other end of the elastic cord being connected to the second unit.

[0016] In one embodiment of the present invention, the first unit is provided with a rotating shaft assembly, the rotating shaft assembly is provided with a first locking part, and the second unit is provided with a second locking part. When the second unit slides to a first position away from the receiving cavity, the first locking part and the second locking part lock together. When the second unit slides from the first position toward the receiving cavity, the first locking part and the second locking part disengage.

[0017] In one embodiment of the present invention, the rotating shaft assembly includes a shaft body and two bushings. The first unit is provided with a mounting groove, and coaxial mounting holes are provided on both sides of the mounting groove. The two bushings are respectively interference-fitted into the mounting holes on both sides. The two ends of the shaft body are respectively inserted into the inner holes of the two bushings. A circumferential stop structure is provided between the shaft body and the bushings.

[0018] In one embodiment of the present invention, the circumferential stop structure includes a plurality of arc teeth, which are evenly distributed along the outer periphery of the shaft body.

[0019] The electronic device of the present invention has an insertion state in which a second unit can be inserted into the first unit, and has a display screen and a keyboard input device that rotate towards each other to an angle. At the same time, through the connection of sliding and rotating, it provides a new opening and closing scheme for laptops, which can adapt to more application scenarios. In addition, the insertion of the second unit into the first unit of the electronic device of the present invention can make better use of the internal space of the first unit, and can have a thinner thickness compared to foldable laptops.

[0047] Please see Figures 1 to 18 The present invention provides an electronic device that offers a new opening and closing solution for laptops, which can adapt to more application scenarios.

[0048] Please see Figures 1 to 7 The electronic device includes: a first unit 100 and a second unit 200.

[0049] Please see Figures 3 to 6The shape of the first unit 100 can refer to the structure and shape of the main body of an existing laptop computer, and typically includes a box with an approximately flat rectangular shape. The box contains a mounting cavity (not shown), which typically houses conventional essential components such as a processor (CPU), memory (RAM), hard disk (or solid-state drive), motherboard, graphics card, and battery. In this invention, the box of the first unit 100 also includes a receiving cavity 102 for the second unit 200 to slide into. One side of the receiving cavity 102 has an opening for the second unit 200 to be inserted into and withdrawn from the receiving cavity 102. The structure and location of the receiving cavity 102 are not limited. The receiving cavity 102 can be part of the mounting cavity or independent of the mounting cavity, and can be arranged in layers along the height direction with the mounting cavity. The depth of the receiving cavity 102 along the sliding direction of the second unit 200 is such that it can at least partially accommodate the second unit 200. Preferably, in this invention, when the second unit 200 is inserted into the receiving cavity 102, along the direction perpendicular to the sliding plane, the projection of the first unit 100 covers the projection of the second unit 200, thereby achieving relative concealment of the second unit 200. The shape of the opening on the receiving cavity 102 is not limited in this invention, as long as it allows the second unit 200 to pass through smoothly. Preferably, in this embodiment, the shape of the opening matches the shape of the second unit 200 to obtain a more aesthetically pleasing effect and a more compact volume.

[0050] In this embodiment, the shape and structure of the second unit 200 can be derived from the display structure of an existing laptop computer, and typically includes a display housing and a display screen 201 mounted on the display housing. The second unit 200 is slidably inserted into the receiving cavity 102 from the opening and is electrically or wirelessly connected to the first unit 100. The sliding insertion method is not limited. Specifically, in this embodiment, the sliding of the second unit 200 within the receiving cavity 102 is achieved through a sliding engagement between the second unit 200 and the wall of the receiving cavity 102. In other embodiments, a sliding rail and a sliding groove can also be used. For example, a sliding groove (or a sliding rail) extending linearly along the sliding direction is provided on the inner wall of the receiving cavity 102, and a sliding rail (or a sliding groove that matches the sliding groove) is provided at a corresponding position on the display housing.

[0051] Please see Figures 3 to 5 On the side of the second unit 200 away from the receiving cavity 102 (i.e. Figure 4When the second unit 200 slides to the first position (in the X direction), it is rotatably connected to the first unit 100. At this time, the first unit 100 and the second unit 200 can rotate relative to each other, and can drive the display screen 201 and the keyboard input device 101 to rotate towards each other to an angle of α, where the angle α is greater than or equal to 0° and less than 180°. The first position can be selected according to design needs, so that the second unit 200 can slide out of the receiving cavity 102, and the sliding connection can be released without interfering with the relative rotation of the second unit 200 and the first unit 100. When the second unit 200 rotates back to the first position, the second unit 200 can slide along the direction of insertion into the receiving cavity 102, and release the rotatable connection with the first unit 100, and slide into the receiving cavity 102. The electronic device of the present invention has an insertion state in which the second unit 200 can be inserted into the first unit 100, and has a state in which the display screen 201 and the keyboard input device 101 rotate toward each other to an angle greater than or equal to 0° and less than 180°. At the same time, through the connection of sliding and rotation, it provides a new opening and closing scheme for laptops, which can adapt to more application scenarios. In addition, when the second unit 200 is inserted into the first unit 100, the internal space of the first unit 100 can be better utilized, and it can have a thinner thickness compared to foldable laptops.

[0052] In this embodiment, the second unit 200 is typically electrically connected to the first unit 100. A ribbon cable (not shown) is located near the rotatable connection point of the second unit 200. One end of the ribbon cable connects to the display screen 201, and the other end connects to an interface on the motherboard to obtain power support and communication signals. In some embodiments, to prevent tangling, an automatic cable release device may be provided within the first unit 100 or the second unit 200. During the sliding of the second unit 200, the ribbon cable extends or winds itself as the second unit 200 moves. Additionally, in other embodiments, both the second unit 200 and the first unit 100 are equipped with batteries. The first unit 100 and the second unit 200 are connected wirelessly. The wireless communication connection method can refer to existing wireless projection technologies, including but not limited to Wi-Fi Display technology (Miracast), AirPlay, and wireless projection devices.

[0053] It should be noted that in this embodiment, the second unit 200 is provided with a display screen 201, and the first unit 100 is provided with a keyboard input device 101. However, in some other embodiments, unlike this embodiment, the first unit 100 is a monitor with the display screen 201 installed, and the second unit 200 is a host computer with the keyboard input device 101 installed. The receiving cavity 102 is disposed inside the monitor, and when the second unit 200 is inserted into the receiving cavity 102, the host computer is inserted into the monitor. It should also be noted that conventional essential components such as the processor (CPU), memory (RAM), hard disk (or solid-state drive), motherboard, graphics card, and battery can also be installed in the second unit 200, or simultaneously distributed in the first unit 100 and the second unit 200. This invention does not impose any limitations on this.

[0054] The type of keyboard input device 101 in this invention is not limited; for example, it can be a mechanical keyboard, a touch keyboard, or a touch-sensitive keyboard. Preferably, in this embodiment, the first unit 100 or the second unit 200 equipped with the keyboard input device 101 includes a touch screen, and the keyboard input device 101 is a touch keyboard displayed on the touch screen. The touch keyboard can be customized according to user preferences, such as adjusting the keyboard layout, size, and color, to provide a more personalized user experience. At the same time, the touch keyboard can save physical space and improve the portability of electronic devices. Furthermore, the touch screen can be used as both a display and input device, reducing the need for additional hardware and making the device more concise.

[0055] In one embodiment, when the keyboard input device 101 is disposed in the first unit 100 and the second unit 200 is inserted into the receiving cavity 102, the display screen 201 is also inserted into the receiving cavity 102. At this time, turning off the touch keyboard allows the electronic device to switch to tablet mode, where operation and display can be performed simultaneously via the touch screen. When the first unit 100 and the second unit 200 are at an angle, the touch keyboard is turned on, and the electronic device switches to laptop mode. In laptop mode, operation is performed via the touch keyboard on the touch screen, and display is performed via the display screen 201. By placing the keyboard input device 101 in the first unit 100 and allowing the second unit 200 to be inserted into the receiving cavity 102, the electronic device can switch between tablet mode and laptop mode according to the user's needs. This design provides more usage scenarios and operating methods, increasing the device's versatility.

[0056] In another embodiment, with Figures 1 to 6Unlike the previous solution, the keyboard input device 101 is located in the second unit 200, and the display screen 201 is located in the first unit 100. The display screen 201 is a touch screen. When the second unit 200 is inserted into the receiving cavity 102, the electronic device switches to a tablet mode where it is operated and displayed via the touch screen. In this mode, the configuration of the keyboard input device 101 is not required, and the touch screen does not need to be installed on the second unit 200. When switching to tablet mode, touch screen operation can be performed directly through the touch screen on the first unit 100. It should be noted that in this embodiment, compared to Figure 5 In the proposed solution, the second unit 200 should be placed on the desktop in laptop mode so that the first unit 100 can be displayed upwards.

[0057] Please refer to 8. Considering that it is difficult to remove the second unit 200 from the receiving cavity 102 when it is fully inserted, in order to provide a better user experience, in one embodiment, an ejection device 400 is provided between the first unit 100 and the second unit 200 for ejecting the second unit 200 from the receiving cavity 102 to at least partially expose it. The structure of the ejection device 400 is not limited, and can be found in existing optical drive ejection devices, SIM card ejection devices, automatic drawer ejection devices, etc., but is not limited thereto. The ejection device 400 allows the second unit 200 to be partially exposed outside the receiver, reducing the difficulty of removing the second unit 200 from the receiving cavity 102 and improving the user experience when removing the second unit 200.

[0058] Please see Figures 8 to 9In one embodiment, the ejection device 400 includes a trigger 420, a compression mechanism 410, and at least one elastic element 401. The receiving cavity 102 includes a cavity wall 103 opposite to the insertion direction of the second unit 200. The compression mechanism 410 and the elastic element 401 are both disposed in the receiving cavity 102 and located on the side near the cavity wall 103. The elastic element 401 can be any suitable component capable of storing energy during deformation and releasing energy during restorative deformation, including but not limited to cylindrical springs, bent leaf springs, etc. Specifically, in this embodiment, the elastic element 401 is a cylindrical spring. The compression direction of the elastic element 401 is parallel to the sliding direction of the second unit 200. One end of the elastic element 401 along the compression direction is mounted on the cavity wall 103, and the other end of the elastic element 401 along the compression direction points towards the second unit 200. The compression mechanism 410 compresses the other end of the elastic element 401, thereby keeping the elastic element 401 in a compressed state. As long as compression of the elastic element 401 can be achieved, the compression mechanism 410 can take many forms, such as a cam compression mechanism that can compress and release the elastic element 401 via a cam, or a crank-slider mechanism that uses a slider to reciprocate linearly to compress and release the elastic element 401, but is not limited to these. The compression mechanism 410 can compress the elastic element 401 by directly compressing the other end of the elastic element 401, or it can indirectly compress the other end of the elastic element 401 by other components. The trigger 420 is movably mounted on the first unit 100 and is configured to trigger the compression mechanism 410 to release the other end of the elastic element 401, so that the elastic element 401 pushes the second unit 200 at least partially exposed from the opening of the receiving cavity 102 during the recovery deformation process. The structure of the trigger 420 corresponds to that of the compression mechanism 410. For example, when the compression mechanism 410 is a cam compression mechanism 410, the trigger 420 can be the cam shaft 307. When the compression mechanism 410 is a crank-slider mechanism, the trigger 420 can be a component that drives the crank to rotate.

[0059] Please see Figure 10 In one embodiment, the compression mechanism 410 includes a first connecting rod 411, a second connecting rod 412, and a first hook portion 414. The first connecting rod 411 is rotatably mounted within the receiving cavity 102. The first hook portion 414 is fixedly connected to the side of the first connecting rod 411 near the second unit 200, and the second connecting rod 412 is fixedly connected to the side of the first connecting rod 411 away from the first hook portion 414. The rotatable mounting method of the first connecting rod 411 is not limited; it can be provided with one support, multiple supports, or directly rotatably mounted on the walls on both sides of the receiving cavity 102, as long as a lever structure is formed between the first hook portion 414 and the second connecting rod 412 during the rotation of the first connecting rod 411.

[0060] Please see Figure 14The trigger 420 includes a trigger body 423 and a reset member 422. The trigger body 423 is located on the side of the second connecting rod 412 opposite to the first connecting rod 411 and slides through the bottom wall of the receiving cavity 102. One end of the trigger body 423 extending into the receiving cavity 102 is fixedly connected to the second connecting rod 412 to trigger the first hook portion 414 to release the elastic member 401. The reset member 422 is disposed in the receiving cavity 102 to reset the trigger body 423 after triggering, thereby resetting the first hook portion 414 to its original position. Specifically, in this embodiment, during the rotation of the second connecting rod 412, the first hook portion 414 has a normal position and a triggered position. The normal position refers to the position where the first hook portion 414 is normally located under the action of the reset member 422 when it is not triggered. The triggered position refers to the position where the first hook portion 414 is located when the trigger body 423 overcomes the action of the reset member 422 and reaches the top. The first hook portion 414 rotates between the normal position and the triggered position. In the normal position, the first hook part 414 compresses the elastic body, keeping the elastic body in a compressed state. In the triggered position, the first hook part 414 disengages from the second hook part 402.

[0061] Please see Figures 10 to 12 In one embodiment, a second hook portion 402 is fixedly connected to one end of the elastic member 401 near the second unit 200. The connection method includes, but is not limited to, welding, bonding, and detachable connection. When the second unit 200 continues to slide towards the receiving cavity 102 after contacting the second hook portion 402, the bottom of the second hook portion 402 presses down on the first hook portion 414 and causes the first hook portion 414 to rotate downward to avoid the second hook portion 402, so that the second hook portion 402 passes through the normal position of the first hook portion 414. After the second hook 402 passes the normal position, the downward pressure applied to the first hook 414 is released. The first hook 414 is reset to the normal position under the action of the reset member 422 and hooks with the second hook 402, thereby keeping the elastic member 401 locked in the compressed state. When the trigger body 423 moves upward to trigger the second link 412, the end of the second link 412 away from the first link 411 moves upward, while the first hook 414 located on the other side of the first link 411 moves downward to the trigger position. The second hook 402 disengages from the first hook 414, the elastic member 401 restores its deformation and pushes the second unit 200 away.

[0062] In one embodiment, with Figures 10 to 12Unlike other designs, the second unit 200 is provided with a second hook part 402. A clearance notch (not shown) is provided between the second hook part 402 and the second unit 200 for the first hook part 414 to hook onto. When the second hook part 402 is connected to the first hook part 414, the position of the second unit 200 is marked as the second position. When the second unit 200 slides from the first position to the second position, the second hook part 402 on the second unit 200 first contacts the first hook part 414. Since the first hook part 414 is in a floating state, during the sliding of the second unit 200, the first hook part 414 rotates downward to avoid the second hook part 402 so that it can pass smoothly. After the second hook part 402 passes, the first hook part 414 rotates upward from the clearance notch to return to its normal position under the action of the reset member 422. At this time, the second hook part 402 is connected to the first hook part 414. When the trigger 423 triggers the second link 412, the first hook 414 moves downward to the trigger position, the second hook 402 disengages from the first hook 414, the elastic element 401 recovers its deformation, and pushes the second unit 200 away. In this embodiment, the position of the second hook 402 corresponds to the position of the elastic element 401. Therefore, during the sliding insertion of the second unit 200, the second hook 402 directly compresses the elastic element 401. However, it should be noted that this does not necessarily mean that the second hook 402 compresses the elastic element 401. The position of the second hook 402 may not correspond to the position of the elastic element 401. Instead, after the first hook 414 and the second hook 402 are connected and the second unit 200 is locked in the receiving cavity 102, the elastic element 401 is directly compressed through the side wall of the second unit 200, thereby keeping the elastic element 401 in a compressed state. Compared to Figures 10 to 12 The second hook 402 is disposed on the elastic member 401. In this embodiment, the solution can not only enable the second unit 200 to pop out quickly, but also enable the second unit 200 to be locked in the receiving cavity 102, which can make the electronic device more stable in the storage state.

[0063] The number of elastic elements 401 in the electronic device of this invention can be only one, but can also be two or more. For considerations regarding force balance and cost, please refer to [link / reference needed]. Figure 9 and Figure 10In one embodiment, the ejection device 400 includes two elastic elements 401, and the compression mechanism 410 further includes a connecting rod fixing seat 413. The connecting rod fixing seat 413 is fixedly installed in the receiving cavity 102, and the fixing method is not limited. In this embodiment, the connecting rod is fixed to the bottom wall 104 of the receiving cavity 102. The two elastic elements 401 are arranged side by side between the second unit 200 and the cavity wall 103, and are respectively located on both sides of the connecting rod fixing seat 413. The compression direction of the two elastic elements 401 is parallel to the sliding direction of the second unit 200. One end of the two elastic elements 401 along the compression direction is installed on the cavity wall 103, and the other end of the two elastic elements 401 along the compression direction points to the second unit 200. A second hook portion 402 is fixedly connected to the end of the elastic element 401 near the second unit 200. The first connecting rod 411 is rotatably installed on the connecting rod fixing seat 413, and a first hook portion 414 is connected to the corresponding position of the two elastic elements 401. As the second unit 200 continues to slide toward the receiving cavity 102 after contacting the two second hooks 402, the bottoms of the two second hooks 402 press down on the corresponding first hook 414, causing the floating first hook 414 to rotate downwards to avoid the second hooks 402, so that the second hooks 402 pass through the normal position of the first hook 414. After the second hook 402 passes its normal position, the downward pressure applied to the first hook 414 is released. Both first hooks 414 return to their normal positions under the action of the same reset member 422 and hook onto their corresponding second hooks 402, thus keeping both elastic members 401 locked in a compressed state. When the trigger body 423 moves upward to trigger the second link 412, the end of the second link 412 away from the first link 411 moves upward, while the two first hooks 414 on the other side of the first link 411 move downward to the trigger position. Simultaneously, the two second hooks 402 disengage from the two first hooks 414, and the two elastic members 401 recover their deformation and simultaneously push the second unit 200 away. Compared to a solution with only one elastic member 401, this embodiment achieves a larger ejection force and makes the ejection force on the second unit 200 more balanced during ejection.

[0064] Please see Figures 12 to 14In this invention, the reset component 422 can be any suitable component capable of resetting the trigger body 423 after the external force is removed, including but not limited to cylindrical springs, bent spring sheets, etc. Specifically, in this embodiment, the reset component 422 includes a reset spring. The reset spring is located on the side of the second connecting rod 412 away from the trigger body 423, and the compression direction is consistent with the sliding direction of the trigger body 423. A fixing plate 421 is provided on the wall of the receiving cavity 102. One end of the reset spring is fixed to the fixing plate 421, and the other end of the reset spring is fixed to the second connecting rod 412. However, those skilled in the art will understand that the other end of the reset spring can also be fixed to the trigger body 423.

[0065] Please see Figure 10 In one embodiment, the electronic device further includes an elastic cord 430 disposed in the receiving cavity 102. One end of the elastic cord 430 is connected to the wall of the receiving cavity 102, and the connection method is not limited. In this embodiment, there are two elastic cords 430, one end of which is connected to the connecting rod fixing seat 413. The other end of one elastic cord 430 is connected to one side of the second unit 200, and the other end of the other elastic cord 430 is connected to the other side of the second unit 200. This arrangement not only allows the elastic cord 430 to pull the second unit 200 when it is ejected by the elastic member 401, preventing the second unit 200 from ejecting too quickly, but also helps to retrieve the second unit.

[0066] In this invention, the rotational connection between the second unit 200 and the first unit 100 in the first position can be varied, for example, please refer to [reference needed]. Figure 15 In some embodiments, a rotating shaft 307 is provided on one of the first unit 100 and the second unit 200, and a slot 306 that can engage with the rotating shaft 307 is provided on the other. The shape of the slot 306 is adapted to the shape of the rotating shaft 307, but a spring-loaded opening is provided on the side facing the rotating shaft 307 for the rotating shaft 307 to engage. When the rotating shaft 307 is engaged in the slot 306, the friction between the rotating shaft 307 and the slot 306 achieves damped rotation between the second unit 200 and the first unit 100, so that the second unit 200 and the first unit 100 are kept at an angle. It should be noted that in this structure, attention should be paid to avoiding interference between the slot 306 and the rotating shaft 307. For example, the slot 306 can be provided only at both ends of the rotating shaft 307 to avoid interference between the connection part of the rotating shaft 307 and the second unit 200 and the slot 306. Alternatively, a mounting slot 110 can be provided on the first unit 100 to provide sufficient space for the rotation of the second unit 200.

[0067] Please see Figures 16 to 18In another embodiment, a rotating shaft assembly 300 is provided on the first unit 100, and a first engaging portion 304 is provided on the rotating shaft assembly 300. A second engaging portion 202 is provided on the second unit 200. When the second unit 200 slides to a first position away from the receiving cavity 102, the first engaging portion 304 engages with the second engaging portion 202. When the second unit 200 slides from the first position toward the receiving cavity 102, the first engaging portion 304 disengages from the second engaging portion 202. Specifically, a support plate 303 is provided on the rotating shaft assembly 300, and a first snap-fit ​​part 304 is provided on the upper side of the support plate 303. The first snap-fit ​​part 304 is an elastic spring structure. The first snap-fit ​​part 304 and the support plate 303 form a snap-fit ​​cavity. The snap-fit ​​cavity has an open slot on the side facing the receiving cavity 102. A second snap-fit ​​part 202 is provided on the second unit 200. The second snap-fit ​​part 202 has a shape that can be inserted into the snap-fit ​​cavity from the slot. When the second snap-fit ​​part 202 is inserted into the first snap-fit ​​part 304, the first snap-fit ​​part 304 presses the second snap-fit ​​part 202, thereby realizing the snap-fit ​​between the first snap-fit ​​part 304 and the second snap-fit ​​part 202. After the snap-fit, the second unit 200 can rotate relative to the first unit 100. When the second unit 200 slides from the first position toward the receiving cavity 102, the second locking part 202 disengages from the locking slot, thereby disengaging from the second locking part 202. After disengagement, the rotational connection between the second unit 200 and the first unit 100 is released, and the second unit 200 can slide relative to the first unit 100.

[0068] Please see Figures 16 to 18 In one embodiment, the rotating shaft assembly 300 includes a shaft body 301 and two bushings 305. A mounting groove 110 is provided on the first unit 100, and coaxial mounting holes are provided on both side walls of the mounting groove 110. The two bushings 305 are respectively interference-fitted into the mounting holes on both sides, so that the bushings 305 rotate with damping relative to the mounting holes. Both ends of the shaft body 301 are respectively inserted into the inner holes of the two bushings 305. A circumferential stop structure 302 is provided between the shaft body 301 and the bushings 305, which can maintain the synchronous rotation between the shaft body 301 and the bushings 305. The circumferential stop structure 302 is not limited to a specific structure, and includes, but is not limited to, a flat key connection structure, a spline connection structure, etc. In one embodiment, the circumferential stop structure 302 includes a plurality of arc teeth 308 disposed at both ends of the shaft body 301. The plurality of arc teeth 308 are evenly distributed along the outer periphery of the shaft body 301. This arrangement can make the force transmission between the shaft body 301 and the bushing 305 more uniform.

[0069] In summary, the electronic device of the present invention has an insertion state in which the second unit can be inserted into the first unit, and has a display screen and keyboard input device that rotate towards each other to an angle. Furthermore, through the connection of sliding and rotation, it provides a new opening and closing scheme for laptops, adaptable to more application scenarios. In addition, the insertion of the second unit into the first unit allows for better utilization of the internal space of the first unit, resulting in a thinner profile compared to foldable laptops. Therefore, the present invention effectively overcomes some practical problems in the prior art, thus having high utilization value and practical significance.
