Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more particularly to an electronic device and its operating method. Background Technology

[0002] In related technologies, the two relatively rotating parts of an electronic device, such as the display screen and the keyboard, cannot be rotated relative to each other to a certain angle and locked. This can easily cause the display screen to accidentally flip while the user is touching it, making operation inconvenient. Summary of the Invention

[0003] This application provides an electronic device and its operating method to improve the ease of operation of the electronic device.

[0004] In a first aspect, embodiments of this application provide an electronic device comprising a first body, a second body, a base, and a mating component. The second body is rotatably connected to the first body; the base is fixed relative to the first body, and a first track is formed on the base, with a first stop portion disposed on the first track; during rotation of the second body, the second body can drive the mating component to slide along the first track; when the second body rotates to a first preset angle, the mating component abuts against the first stop portion in the direction of rotation of the second body to restrict the rotation of the second body.

[0005] In some embodiments of this application, the first track includes a first arc segment and an extension segment. The first arc segment and the extension segment have a first height difference along a first direction. A first stop is disposed on the side of the extension segment away from the first arc segment. The first direction is parallel to the axis of rotation of the second body. When the mating part slides along the first track, the mating part can abut against the first track along the first direction.

[0006] In some embodiments of this application, a second stop is formed on the side of the extension segment that is close to the first arc segment. When the second body rotates from the first preset angle to the first angle, the mating member abuts against the second stop to disengage the mating member from the extension segment and enter the second track.

[0007] In some embodiments of this application, a second track is formed on the base. The second track includes an initial segment and a second arc segment. The initial segment and the extension segment have a second height difference in a first direction. The second body can drive the mating member to slide along the second track to a second angle by means of the second height difference mating member to disengage from the extension segment and enter the second track.

[0008] In some embodiments of this application, a third arc segment is formed on the side of the initial segment away from the extension segment on the second track. The initial segment and the third arc segment have a third height difference in a first direction. The third arc segment is connected to the second arc segment. The second arc segment and the third arc segment form part of the third track. The second body can drive the mating member to slide along the third track to fit with the first body.

[0009] In some embodiments of this application, the portion connecting the initial segment and the second arc segment has a fourth height difference in a first direction. When the second body is opened relative to the first body, the mating member can enter the second arc segment from the initial segment. When the second body is fitted relative to the first body, the fourth height difference restricts the mating member from returning to the initial segment from the second arc segment.

[0010] In some embodiments of this application, the extension segment, the initial segment, and the third arc segment are arranged radially in sequence along the rotation axis of the second body.

[0011] In some embodiments of this application, the electronic device further includes a mounting member and an elastic member. The mounting member is fixed relative to the second body and has a guide through hole formed thereon. The guide through hole penetrates the mounting member along a first direction. A mating member passes through the guide through hole so as to be able to slide relative to the second body. The second body, the mounting member, and the base are arranged along the first direction. The mounting base is located between the second body and the base. The electronic device further includes an elastic member that is supported between the second body and the mating member along the first direction so as to apply a force toward the base to the mating member.

[0012] In some embodiments of this application, one of the first body and the other of the second body is an input device and the other is a display device, and the display device and the input device are arranged opposite to each other.

[0013] Secondly, this application provides an operation method applied to the electronic device provided in the first aspect of this application. The operation method includes: during the unfolding of the second body relative to the first body, the second body can drive the mating member to slide along the first track. When the second body rotates to a first preset angle, the mating member abuts against the first stop portion along the direction of rotation of the second body to restrict the rotation of the second body.

[0014] The electronic device provided in this application embodiment allows the mating component to slide along the first track to abut against the first stop when the second body rotates to a first preset angle, thus hindering the rotation of the second body. In this way, the second body can rotate relative to the first body to a certain angle and then lock, preventing accidental flipping even if the user applies significant force when touching the second body, thereby improving the ease of operation of the electronic device.

[0031] This application provides an electronic device. The electronic device in this application can take many forms; for example, it can refer to a laptop computer, a mobile phone, or a smart wearable device, etc.

[0032] Please refer to Figures 1-4The electronic device provided in this application includes a first body 1, a second body 2, a base 3, and a mating component 4. The second body 2 is rotatably connected to the first body 1. The base 3 is fixed relative to the first body 1, and a first track 31 is formed on the base 3. A first stop 311 is provided on the first track 31. During the rotation of the second body 2, the second body 2 can drive the mating component 4 to slide along the first track 31. When the second body 2 rotates to a first preset angle, the mating component 4 abuts against the first stop 311 in the direction of rotation of the second body 2, thereby restricting the rotation of the second body 2. With this structure, when the second body 2 rotates to the first preset angle, the mating component 4 can slide along the first track 31 to abut against the first stop 311, thus hindering the rotation of the second body 2. In this way, the second body 2 can lock after rotating relative to the first body 1 to a certain angle. Even if the user applies significant force when touching the second body 2, the second body 2 is less likely to accidentally flip over, which improves the ease of operation of the electronic device.

[0033] Please refer to Figures 1-4 It should be noted that, in the embodiments of this application, the rotation of the second body 2 refers to the rotation of the second body 2 relative to the first body 1.

[0034] Please refer to Figures 1-4 In some embodiments of this application, one of the first body 1 and the second body 2 is an input device, and the other is a display device, with the display device and input device disposed opposite to each other. The display device and input device can have various implementations. In some embodiments of this application, the electronic device is a laptop computer, the display device is the laptop computer's screen, and the input device is the laptop computer's keyboard. In some embodiments of this application, the electronic device can also be a flip phone, the display device is the flip phone's screen, and the input device is the flip phone's keyboard. In some embodiments of this application, the electronic device can also be a foldable phone, the display device is one fold of the foldable phone screen, and the input device is the other fold of the foldable phone screen.

[0035] Please refer to Figures 1-4In this application embodiment, the base 3 can be fixed relative to the first body 1 in various ways. Exemplarily, the base 3 can be fixed to the first body 1 by means of snap-fit, adhesive bonding, thermoforming, welding, fastener connection, or integral molding. In some embodiments of this application, the electronic device further includes a rotating shaft 5, with the first body 1 and the second body 2 rotatably connected via the rotating shaft 5. The axis of relative rotation between the first body 1 and the second body 2 is the axis of the rotating shaft 5. The rotating shaft 5 is fixed together with the first body 1. The base 3 has an insertion hole, and the rotating shaft 5 is inserted into the insertion hole along its axial direction. The radial cross-section of the insertion hole is different from a circle to restrict the relative rotation between the rotating shaft 5 and the insertion hole, thereby fixing the rotating shaft 5 relative to the base 3, and consequently fixing the base 3 relative to the first body 1.

[0036] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments of this application, the first track 31 includes a first arc segment 313 and an extension segment 312. The first arc segment 313 and the extension segment 312 have a first height difference along a first direction a. A first stop 311 is disposed on the side of the extension segment 312 away from the first arc segment 313. The first direction a is parallel to the axis of rotation of the second body 2. When the mating member 4 slides along the first track 31, the mating member 4 can abut against the first track 31 along the first direction a. With this structure, during the rotation of the first body 1, the mating member 4 can slide from the first arc segment 313 into the extension segment 312, and then abut against the first stop 311 located at the end of the extension segment 312 away from the first arc segment 313, thereby restricting the rotation of the second body 2. It can be understood that, along the rotation direction of the second body 2, the first stop 311 is located at one end of the extension segment 312, and the first arc segment 313 is located at the other end of the extension segment 312.

[0037] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments of this application, a second stop 314 is formed on the side of the extension segment 312 that is close to the first arc segment 313. When the second body 2 rotates from the first preset angle to the second stop 314, the mating member 4 abuts against the second stop 314, causing the mating member 4 to disengage from the extension segment 312 and enter the second track 32. With this structure, the abutment between the mating member 4 and the second stop 314 allows the mating member 4 to disengage from the extension segment 312, thereby causing the mating member 4 and the first stop 311 to be offset along the rotation direction of the second body 2. Thus, the first stop 311 will not obstruct the rotation of the second body 2, allowing the second body 2 to continue rotating. This allows the second body 2 to both rotate to the first preset angle and lock, and then rotate back a certain angle and continue rotating beyond the first preset angle, resulting in a large rotation range for the second body 2.

[0038] The first preset angle here can be in the range of 110 degrees to 130 degrees, which allows users to comfortably use the monitor. Of course, this preset angle can be determined based on common user habits.

[0039] Please refer to Figure 4 , Figure 5 and Figure 6 It is understood that in this embodiment, the first arc segment 313 and the extension segment 312 have a first height difference along the first direction a. During the sliding process of the mating member 4 from the first arc segment 313 to the extension segment 312, it will move along the first direction a to be lower than the first arc segment 313. Thus, when the second body 2 rotates from the first preset angle to the first angle, the mating member 4 will abut against the second stop portion 314 to disengage from the extension segment 312 and enter the second track 32. In some embodiments of this application, the first track 31 and the second track 32 are arranged radially along the rotation axis 5 of the second body 2. In some embodiments of this application, the second track 32 is located on the side of the first track 31 closest to the rotation axis 5 of the second body 2.

[0040] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments of this application, the mating member 4 and the second body 2 are capable of relative sliding. The relative sliding direction between the mating member 4 and the second body 2 is different from the rotation direction of the second body 2, so that when the second stop portion 314 of the mating member 4 abuts, the mating member 4 can slide along the second stop portion 314 to disengage from the extension section 312 and enter the second track 32. With this structural form, the disengagement of the mating member 4 from the extension section 312 can be achieved relatively easily, and the processing cost is low.

[0041] Please refer to Figures 1-4 In some embodiments of this application, the electronic device further includes a mounting member 6 and an elastic member 7. The mounting member 6 is fixed relative to the second body 2. A guide hole 61 is formed on the mounting member 6, which penetrates the mounting member 6 along a first direction a. The mating member 4 passes through the guide hole 61 to slide relative to the second body 2. The second body 2, the mounting member 6, and the base 3 are arranged along the first direction a, with the mounting base located between the second body 2 and the base 3. The electronic device also includes an elastic member 7, which is supported between the second body 2 and the mating member 4 along the first direction a to apply a force toward the base 3 to the mating member 4. With this structure, the installation of the mating member 4 on the second body 2 is more convenient. The elastic member 7 applies a stationary force along the first direction a to the mating member 4, allowing the mating member 4 to enter the extension section 312 from the first arc segment 313 through the first height difference during sliding along the first track 31.

[0042] Please refer to Figures 1-4In some embodiments of this application, the electronic device further includes a spring mounting member 8, one end of which abuts against the second body 2 along the first direction a, and the other end of which is inserted into the mating member 4 along the first direction a. The elastic member 7 is a compression spring that extends along the first direction a and is sleeved on the spring mounting member 8 along the first direction a, with both ends abutting against the spring mounting member 8 and the mating member 4, respectively. With this structural configuration, the installation of the elastic member 7 is more stable and reliable.

[0043] Please refer to Figures 1-4 In some embodiments of this application, the mounting member 6 has a mounting hole 62, and the rotating shaft 5 passes through the mounting hole 62 axially to be rotatably connected to the mounting member 6. This structural form is beneficial to improving the compactness of the structure.

[0044] Please refer to Figure 7 and Figure 8 In some embodiments of this application, along the direction of rotation of the second body 2, one end of the second track 32 extends to the end of the first arc segment 313 away from the extension segment 312, so that during the rotation of the second body 2, the second body 2 can drive the mating member 4 to slide along the second track 32 to the first arc segment 313. With this structure, when the mating member 4 is located within the second track 32, the rotation of the second body 2 can cause the mating member 4 to slide along the second track 32 to the first arc segment 313, thereby allowing the mating member 4 to slide again along the first track 31. In this way, the mating member 4 can perform cyclical movement between the first track 31 and the second track 32.

[0045] Please refer to Figure 7 and Figure 8In some embodiments of this application, a second track 32 is formed on the base 3. The second track 32 includes an initial segment 321 and a second arc segment 322. The initial segment 321 and the extension segment 312 have a second height difference in the first direction a. A fitting member 4, utilizing the second height difference, disengages from the extension segment 312 and enters the second track 32. The second body 2 can drive the fitting member 4 to slide along the second track 32 to a second angle. With this structure, the fitting member 4 can disengage from the extension segment 312 and enter the second track 32 using the second height difference. Moreover, due to the existence of the second height difference, the fitting member 4 is less likely to return from the second track 32 to the first track 31 during the rotation of the second body 2, which facilitates smoother rotation of the second body 2. It is understood that the fitting member 4 disengages from the extension segment 312 and enters the second track 32 using the second height difference fitting member 4, meaning that the fitting member 4 is influenced by a stationary force and has a tendency to move along the first direction a, thus enabling it to disengage from the extension segment 312 and enter the second track 32. The stationary force can be gravity or the elastic force of a spring, etc. In some embodiments of this application, the second angle can be implemented in various ways. For example, the second angle can be greater than 180 degrees; exemplarily, the second angle is 360 degrees. In this way, the rotation range of the second body 2 is relatively large.

[0046] Please refer to Figure 7 and Figure 8 In some embodiments of this application, the initial segment 321 is provided with a second extension segment (not shown) along the rotation direction of the second body 2. The second extension segment has a groove structure similar to the extension segment 312 on the first track, and its two ends form a third stop and a fourth stop (not shown). When the second body 2 enters the second track 32 from the first track 31, and the second body 2 continues to move away from the first body in the rotation direction, the mating member 4 slides along the initial segment 321 under the drive of the second body 2. The third stop can abut against the mating member 4 when the second body 2 unfolds to a second predetermined angle to restrict the movement of the second body 2. The second predetermined angle is greater than the first predetermined angle. The fourth stop is used to abut against the mating member 4 during the rotation of the second body 2 so that the mating member 4 disengages from the initial segment 321 and enters the third track. With this structure, the third stop can restrict the rotation of the second body 2 when the second body 2 unfolds to the second predetermined angle, so that during the rotation of the second body 2, the third stop and the first stop 311 can achieve multi-level locking of the unfolding angle of the second body 2. The fourth stop is used to abut against the mating part 4 during the rotation of the second body 2, so that the mating part 4 is disengaged from the initial section 321, thereby causing the mating part 4 to be misaligned with the third stop, so that the second body 2 can pass over the third stop during the rotation and achieve further rotation.

[0047] In this embodiment, setting multiple locking levels can meet the user's needs for different unfolding angles and improve the user experience. For example, sometimes some users are used to using electronic devices at 120 degrees, and sometimes some users are used to using electronic devices at 140 degrees.

[0048] Please refer to Figure 7 , Figure 8 and Figure 9 In some embodiments of this application, a third arc segment 323 is formed on the side of the initial segment 321 on the second track 32 away from the extension segment 312. The initial segment 321 and the third arc segment 323 have a third height difference in the first direction a. The third arc segment 323 is connected to the second arc segment 322, wherein the second arc segment 322 and the third arc segment 323 form part of the third track. The second body 2 can drive the mating part 4 to slide along the third track to fit against the first body 1. With this structure, during the rotation of the second body 2, the second body 2 can enter the third arc segment 323 from the initial segment 321 through the third height difference. Moreover, due to the existence of the third height difference, during the rotation of the second body 2, the mating part 4 is not easy to return from the third arc segment 323 to the initial segment 321, which is beneficial to make the rotation of the second body 2 smoother. In some embodiments of this application, the extension segment 312, the initial segment 321, and the third arc segment 323 are arranged radially in sequence along the rotation axis of the second body 2. With this structural form, during the rotation of the second body 2, the mating part 4 can sequentially enter the initial section 321 from the extension section 312 and the third arc section 323 under the action of the second height difference and the third height difference.

[0049] Please refer to Figure 7 , Figure 8 and Figure 9 In some embodiments of this application, the portion connecting the initial segment 321 and the second arc segment 322 has a fourth height difference in the first direction a. When the second body 2 opens relative to the first body 1, the mating member 4 can enter the second arc segment 322 from the initial segment 321. When the second body 2 is in contact with the first body 1, the fourth height difference restricts the mating member 4 from returning from the second arc segment 322 to the initial segment 321. With this structure, during the rotation of the second body 2, the mating member 4 can enter the second arc segment 322 from the initial segment 321 under the action of the fourth height difference, and the fourth height difference can restrict the mating member 4 from returning from the second arc segment 322 to the initial segment 321, which is beneficial to the smooth rotation of the second body 2.

[0050] Please refer to Figure 7 , Figure 8 and Figure 9In some embodiments of this application, along the rotation direction of the second body 2, one end of the third arc segment 323 extends to the end of the first arc segment 313 away from the extension segment 312, so that during the rotation of the second body 2, the second body 2 can drive the mating member 4 to slide along the third arc segment 323 to the first arc segment 313. With this structure, when the mating member 4 is located within the third arc segment 323, the rotation of the second body 2 can cause the mating member 4 to slide along the third arc segment 323 to the first arc segment 313, thereby allowing the mating member 4 to slide again along the first track 31. In this way, the mating member 4 can perform cyclical movement within the first track 31, the second track 32, and the third track.

[0051] Please refer to Figures 1-4 This application also provides an operation method for the electronic device provided in this application. The operation method includes the following steps: During the unfolding of the second body 2 relative to the first body 1, the second body 2 can drive the mating member 4 to slide along the first track 31. When the second body 2 rotates to a first preset angle, the mating member 4 abuts against the first stop portion 311 in the direction of rotation of the second body 2 to restrict the rotation of the second body 2. In this way, the second body 2 can lock after rotating to a certain angle relative to the first body 1. Even if the user applies significant force when touching the second body 2, the second body 2 is less likely to accidentally flip over, which improves the ease of operation of the electronic device.

[0052] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
