Description

Technical Field

[0001] The present application relates to the technical field of electronic products, and in particular to a rotating device and an electronic device. Background Art

[0002] Laptop computers are popular due to their small footprint, light weight and convenience. Generally speaking, a laptop computer includes a host part and a display part. The host part and the display part are mechanically connected by a hinge assembly so that they can rotate relative to each other; the host part and the display part are also electrically connected by a signal line so that signals can be transmitted between them.

[0003] The signal line extends from the inside of the host part to the inside of the display part via the hinge assembly. In order to prevent the signal line at the hinge assembly from being exposed outside the laptop, a hinge cover is usually installed outside the hinge. The hinge cover is snap-fitted to the shell of the display part through a buckle, and together with the hinge assembly, it forms a receiving cavity for receiving the signal line. However, this solution of installing the hinge cover through a buckle takes up a large space and cannot meet the requirements of aesthetics and refinement. Utility Model Content

[0004] Some embodiments of the present application provide a rotating device and an electronic device. The present application is introduced from multiple aspects below, and the embodiments and beneficial effects of the following aspects can be referenced to each other.

[0005] In a first aspect, an embodiment of the present application provides a rotating device, which includes a shaft assembly and a shaft cover. The shaft assembly is capable of rotating around a first axis. The shaft cover is mounted on the shaft assembly and together with the shaft assembly, forms a receiving cavity. The receiving cavity is used to receive a signal line of an electronic device in which the rotating device is located. Along the extension direction of the first axis, one end of the shaft assembly is provided with a first arc-shaped wall, and one end of the shaft cover is provided with a second arc-shaped wall. The first arc-shaped wall and the second arc-shaped wall are arranged relative to each other and fixedly connected along the extension direction of the first axis.

[0006] In the above-mentioned rotating device, the shaft assembly and the shaft cover are installed and matched by a fixed connection between the first arc-shaped wall and the second arc-shaped wall, which makes full use of the axial space and does not occupy a large radial space. The rotating device as a whole looks more slender and beautiful, with a more beautiful and refined appearance, and can effectively save space, which is conducive to a lightweight and miniaturized design.

[0007] In some embodiments, one of the first arc-shaped wall and the second arc-shaped wall is provided with a mounting groove, and the other is provided with a mounting buckle, wherein the mounting groove cooperates with the mounting buckle, so that the first arc-shaped wall and the second arc-shaped wall can be fixedly connected.

[0008] In some embodiments, the mounting groove includes a fixing groove, and the mounting buckle includes a fixing buckle, wherein the fixing groove cooperates with the fixing buckle, and the fixing groove provides the fixing buckle with a limit position along the circumference of the rotating shaft assembly.

[0009] In this way, it can be ensured that the shaft cover will not rotate significantly along the circumference of the shaft assembly and fall off the shaft assembly when installed on the shaft assembly, thereby effectively ensuring the installation reliability of the shaft cover.

[0010] In some embodiments, one of the fixing groove and the fixing buckle is disposed at an end of the first arc-shaped wall along its circumference, and the other is disposed at an end of the second arc-shaped wall along its circumference. In this way, the shaft cover can be prevented from interfering with other components during installation.

[0011] In some embodiments, the end of the first arc-shaped wall and the end of the second arc-shaped wall respectively include elastic arms extending along the circumference of the shaft assembly, and one of the fixing groove and the fixing buckle is arranged on the elastic arm of the first arc-shaped wall, and the other is arranged on the elastic arm of the second arc-shaped wall.

[0012] In this way, in the process of buckling the fixing buckle into the fixing groove, the elastic arm can more easily produce elastic deformation, so that the fixing buckle can be buckled into the fixing groove more smoothly, effectively reducing the difficulty of buckling between the fixing buckle and the fixing groove, and further improving the assembly efficiency.

[0013] In some embodiments, the second arc-shaped wall includes a reinforcement portion, which is connected to the elastic arm of the second arc-shaped wall, and the wall thickness of the reinforcement portion is greater than the wall thickness of the elastic arm of the second arc-shaped wall.

[0014] By providing the reinforcement part, the thickness of the second arc-shaped wall can be partially increased, thereby further improving the strength of the second arc-shaped wall, thereby ensuring the installation reliability of the shaft cover. At the same time, it will not affect the elastic deformation ability of the elastic arm, ensuring that the fixing buckle can be smoothly buckled into the fixing groove.

[0015] In some embodiments, the first arc-shaped wall and the second arc-shaped wall are provided with a first guide surface on the arc-shaped wall provided with the fixing groove, and the fixing buckle is provided with a second guide surface, which cooperates with the first guide surface to guide the fixing buckle to buckle into the fixing groove.

[0016] By providing the first guide surface and the second guide surface, the fixing buckle can be buckled into the fixing groove more smoothly. Therefore, the first guide surface and the second guide surface can effectively reduce the buckling difficulty between the fixing buckle and the fixing groove, further improving the assembly efficiency.

[0017] In some embodiments, the mounting groove includes a sliding groove, and the mounting buckle includes a sliding buckle. The sliding groove cooperates with the sliding buckle, and the sliding buckle is slidably disposed in the sliding groove, the sliding groove extends along the circumference of the rotating shaft assembly, and provides a radial limit for the sliding buckle along the rotating shaft assembly, which is radially perpendicular to the extension direction of the first axis.

[0018] In this way, it can be ensured that when the shaft cover is installed on the shaft assembly, it will not be displaced significantly in the radial direction of the shaft assembly and fall off from the shaft assembly, thereby effectively ensuring the installation reliability of the shaft cover.

[0019] In some embodiments, a notch is formed on the wall of the sliding groove, and the notch connects the inside of the sliding groove with the outside of the sliding groove. In this way, the sliding buckle can slide into the sliding groove through the notch, thereby further improving the convenience of assembly between the rotating shaft assembly and the rotating shaft cover.

[0020] In some embodiments, a first stop surface is provided on the rotating shaft assembly, and a second stop surface is provided on the rotating shaft cover, and the first stop surface cooperates with the second stop surface to provide the rotating shaft cover with a limit along the circumference of the rotating shaft assembly.

[0021] That is, in an embodiment of the present application, when the shaft cover is installed on the shaft assembly, the first stop surface can cooperate with the second stop surface, so as to provide the shaft cover with a circumferential limit along the shaft assembly, ensuring that the shaft cover will not continue to rotate along the circumference of the shaft assembly, so that the shaft cover can remain in the correct position.

[0022] In some embodiments, the first arc-shaped wall and the second arc-shaped wall are pressed against each other along the extension direction of the first axis, or the first arc-shaped wall and the second arc-shaped wall are pressed against each other along the radial direction of the shaft assembly, which is perpendicular to the extension direction of the first axis. In this way, the first arc-shaped wall and the second arc-shaped wall can be fixedly connected.

[0023] In some embodiments, the shaft assembly includes a third arc-shaped wall, and the shaft cover includes a fourth arc-shaped wall. Along the extension direction of the first axis, the third arc-shaped wall and the first arc-shaped wall are respectively located at opposite ends of the shaft assembly, the fourth arc-shaped wall and the second arc-shaped wall are respectively located at opposite ends of the shaft cover, and the third arc-shaped wall and the fourth arc-shaped wall are relatively arranged and fixedly connected.

[0024] That is, in the embodiment of the present application, along the extension direction of the first axis, the arc-shaped walls located at the opposite ends of the shaft assembly respectively cooperate with the arc-shaped walls located at the opposite ends of the shaft cover, thereby realizing a fixed connection between the shaft assembly and the shaft cover, which can effectively improve the installation reliability between the shaft assembly and the shaft cover.

[0025] In some embodiments, one of the third arc-shaped wall and the fourth arc-shaped wall is provided with a mounting groove, and the other is provided with a mounting buckle, and the mounting groove cooperates with the mounting buckle, so that the third arc-shaped wall and the fourth arc-shaped wall can be fixedly connected.

[0026] In some embodiments, the third arc-shaped wall and the fourth arc-shaped wall are pressed against each other along the extension direction of the first axis, or the third arc-shaped wall and the fourth arc-shaped wall are pressed against each other along the radial direction of the shaft assembly, which is perpendicular to the extension direction of the first axis. In this way, the third arc-shaped wall and the fourth arc-shaped wall can be fixedly connected.

[0027] In some embodiments, the material of the shaft cover is metal or plastic. In this way, there are more types of materials to choose from for the shaft cover, and it is easier to obtain various appearance effects, thereby meeting various appearance design requirements and further improving the appearance refinement and beauty.

[0028] In a second aspect, an embodiment of the present application provides an electronic device. The electronic device includes a first body, a second body, a signal line, and a rotating device provided by any embodiment of the first aspect of the present application.

[0046] The specific implementation of the present application will be described in detail below with reference to the accompanying drawings.

[0047] The present application provides a rotating device, which can be applied to electronic devices. Specifically, the electronic devices include but are not limited to notebook computers, laptop computers, tablet personal computers, e-book readers, personal digital assistants (PDAs), personal computers, headphones, glasses (e.g., augmented reality (AR) glasses, virtual reality (VR) glasses, mixed reality (MR) glasses), and other electronic devices that need to be opened and closed synchronously.

[0048] For the convenience of description, the following describes the technical solution of the present application by taking the electronic device as a laptop computer as an example. In addition, for the convenience of description, the state of the laptop computer after being closed is defined as the closed state, the state of the laptop computer after being opened is defined as the unfolded state, and the state of the laptop computer between the closed state and the unfolded state is defined as the intermediate state, or the hovering state.

[0049] Figure 1A and Figure 1B The structure diagram of the notebook computer 1 in the embodiment of the present application is shown, wherein: Figure 1A is a schematic diagram of the unfolded state of the notebook computer 1, Figure 1B Schematic diagram of the notebook computer 1 in a closed state.

[0050] refer to Figure 1A and Figure 1B The laptop computer 1 includes a main body 01, a display part 02 and a rotating device 03. The main body 01 and the display part 02 are rotatably connected by the rotating device 03, so that the display part 02 can rotate relative to the main body 01 around the rotation axis L1, thereby enabling the laptop computer 1 to be in the unfolded state (for example Figure 1A shown) and closed state (e.g. Figure 1B Switch between them at will.

[0051] When the notebook computer 1 is in a closed state, the angle between the main body part 01 and the display part 02 may approach 0°, that is, the main body part 01 and the display part 02 are stacked.

[0052] When the notebook computer 1 is in the unfolded state, the angle between the main unit 01 and the display unit 02 can be 90° to 150°, that is, the main unit 01 and the display unit 02 are away from each other, so that the operation area of ​​the main unit 01 (for example, Figure 1A The area shown with the keyboard 12 and the touch pad 13) and the display area of ​​the display portion 02 (for example, the area where the screen 22 is located) can be facing the user at the same time for the user to use.

[0053] In order to facilitate the subsequent description, before introducing the specific structure of each component in the notebook computer 1, this application first combines Figure 1AThe X-axis direction, the Y-axis direction, and the Z-axis direction are defined. The X-axis direction is the length direction of the laptop computer 1. For example, the X-axis direction is parallel to the extension direction of the rotation axis L1, and the positive direction of the X-axis can be the direction from left to right when the laptop computer 1 is in normal use; the Y-axis direction is the width direction of the laptop computer 1. For example, the Y-axis direction is perpendicular to the extension direction of the rotation axis of the display part 02, and the positive direction of the Y-axis can be the direction from back to front when the laptop computer 1 is in normal use; the Z-axis direction is the thickness direction of the laptop computer 1. For example, the positive direction of the Z-axis can be the direction from bottom to top when the laptop computer 1 is in normal use.

[0054] It can be understood that, in the process of switching the laptop computer 1 from the closed state to the unfolded state, the dimensions of the laptop computer 1 in the width direction and the thickness direction are gradually increased.

[0055] It can be understood that the mutual parallelism in the present application is not absolute parallelism, and the approximate parallelism caused by processing errors and assembly errors (for example, the angle between the two structural features is 0.1°) is also within the scope of the mutual parallelism in the present application. The mutual perpendicularity in the present application is not absolute perpendicularity, and the approximate perpendicularity caused by processing errors and assembly errors (for example, the angle between the two structural features is 89.9°) is also within the scope of the mutual perpendicularity in the present application. The limitations of mutual parallelism and mutual perpendicularity will not be repeated in the following text.

[0056] In addition, it should be noted that the directional terms such as "up", "down", "left", "right", "front", "back", "top" and "bottom" in this document refer to the orientation of the laptop computer 1 in normal use (for example, in normal use, the main unit 01 is located at the bottom of the laptop computer 1), and do not indicate or imply that the referred component must have a specific orientation, which may change accordingly according to actual use and should not be understood as a limitation on this application.

[0057] Continue reading Figure 1A and Figure 1B The host part 01 includes a host body 11, a keyboard 12, and a touchpad 13. A receiving cavity (not shown) is formed inside the host body 11. The receiving cavity is used to receive various electronic components, such as a processor or a memory, to process and store information. The keyboard 12 and the touchpad 13 are respectively arranged on the host body 11. The keyboard 12 is used to input characters and control commands, and the touchpad 13 is used to control the movement and click of the cursor.

[0058] The display part 02 includes a housing 21 and a screen 22. The housing 21 is covered on the edge of the screen 22 and the back of the screen 22 to protect the screen 22. The screen 22 is used to display information such as images and videos, and can also integrate a touch function. The screen 22 can be a flexible display screen or a rigid display screen. It can be understood that the screen 22 here can be a liquid crystal display (LCD), an organic light emitting diode (OLED) display screen or a quantum dot light emitting diode (QLED) display screen, etc.

[0059] The housing 21 and the screen 22 may together form a receiving cavity (not shown). The receiving cavity is used to receive various electronic components, such as a backlight module, a driving board (or display control board), and other components.

[0060] In order to transmit signals between the main body 01 and the display part 02, a signal line 04 is also provided inside the laptop computer 1. The signal line 04 extends from the inside of the main body 01 to the inside of the display part 02 via the inside of the rotating device 03, thereby realizing electrical connection between the electronic components inside the main body 01 and the electronic components inside the display part 02. For example, the main board in the main body 01 can be electrically connected to the driving board inside the display part 02 through the signal line 04, so as to transmit video signals and power. In some embodiments, the signal line 04 can be a cable or a flexible printed circuit (FPC).

[0061] In order to prevent the signal line 04 from being exposed outside the notebook computer 1, the rotating device 03 generally includes a rotating shaft assembly and a rotating shaft cover, wherein the rotating shaft assembly is used to realize the relative rotation between the main body 01 and the display part 02. The rotating shaft cover is arranged on the outer peripheral surface of the rotating shaft assembly, and together with the rotating shaft assembly, forms a receiving cavity, and the receiving cavity is used to receive the signal line 04. The rotating shaft cover can protect and conceal the signal line 04.

[0062] In some technical solutions, the hinge cover is fixed to the housing 21 of the display part 02 by a snap-fit ​​structure. It is worth noting that the snap-fit ​​structure occupies a relatively large space, and the housing 21 of the display part 02 needs to reserve a large space to install the snap-fit ​​structure. Therefore, the housing 21 of the display part 02 cannot achieve a narrow edge design, resulting in a low appearance and refinement of the notebook computer 1. Secondly, the display part 02 needs to reserve a certain space for the elastic deformation of the snap-fit, which will occupy a large space inside the display part 02.

[0063] In order to solve the above problems, an embodiment of the present application provides a rotating device. Compared with the above-mentioned hinge cover that is fixed to the shell of the display part through a snap-fit ​​structure, the hinge cover in the rotating device provided by the present application is installed on the hinge assembly instead of on the shell of the display part, which can effectively save space and make the overall size of the rotating device smaller. It will not occupy the space inside the display part and affect the appearance of the display part, thereby effectively improving the appearance and sophistication of the laptop computer.

[0064] The technical solution of the present application is described in detail below with reference to the accompanying drawings.

[0065] Figure 2A and Figure 2B The exemplary configuration of the rotating device 03 in the notebook computer 1 in the embodiment of the present application is shown, wherein: Figure 2A is a three-dimensional diagram of a part of the structure of the notebook computer 1, Figure 2B FIG. 1 is an exploded view of a part of the structure of the notebook computer 1, wherein the dotted arrows schematically show the assembly relationship of the various components in the notebook computer 1. For easy distinction, Figure 2A and Figure 2B The structural features of the host part 01 are shown by dot-dashed lines. Figure 3A and Figure 3B The exemplary structure of the rotating device 03 in the embodiment of the present application is shown, wherein: Figure 3A is a three-dimensional diagram of the rotating device 03, Figure 3B FIG. 1 is an exploded view of the rotating device 03, wherein the dotted arrows schematically illustrate the assembly relationship of the various components in the rotating device 03. Figure 3A and Figure 3B Combined with Figure 2A and Figure 2B The rotating device 03 includes a rotating shaft assembly 10 and a rotating shaft cover 20.

[0066] The hinge assembly 10 can rotate around a rotation axis L1 (as an example of a first axis). The hinge assembly 10 is used to connect between a host part 01 (as an example of a first body, not shown) and a display part 02 (as an example of a second body) so that the host part 01 and the display part 02 can rotate relative to each other.

[0067] In some implementations, the hinge assembly 10 may include a first mounting end 101 and a second mounting end 102 connected to each other, wherein the first mounting end 101 is used to connect to the host part 01 , and the second mounting end 102 is used to connect to the display part 02 .

[0068] For example, the first mounting end 101 may be a rotating shaft, which may be rotatably connected to the main unit 01, and its rotation axis may be, for example, the axis L1. The second mounting end 102 may also be referred to as a rotating bearing bracket. The left connecting portion 1021 of the second mounting end 102 is similar to a plate, extending into the interior of the display unit 01, and is used to connect the display unit 02; the right connecting portion 1022 is similar to an arc shape, and is used to support and mount the first mounting end 101. For example Figure 2B As shown, when the notebook computer 1 is in a flattened state, the right connecting portion 1022 is at least partially located between the host portion 01 and the display portion 02 .

[0069] Along the X-axis direction, one end of the shaft assembly 10 is provided with a first arc-shaped wall 100. For example, the first arc-shaped wall 100 can be provided at one end of the right connecting portion 1022 of the second mounting end 102 along the X-axis direction. The first arc-shaped wall 100 can extend along the circumference of the shaft assembly 10, wherein the circumference of the shaft assembly 10 can be, for example, Figure 3A and Figure 3B It can be understood that the circumference of the first arc-shaped wall 100 can be the same as the circumference of the shaft assembly 10. For example, the circumference of the first arc-shaped wall 100 can also be Figure 3A and Figure 3B The N direction in .

[0070] Along the X-axis direction, one end of the rotating shaft cover 20 is provided with a second arc-shaped wall 200. The second arc-shaped wall 200 can extend along the N direction. It can be understood that the circumference of the second arc-shaped wall 200 can be the N direction. The second arc-shaped wall 200 and the first arc-shaped wall 100 are two walls arranged opposite to each other along the X-axis direction. Among them, in the present application, component A and component B are arranged opposite to each other along a certain direction, which means that component A and component B are arranged face to face in this direction, and the projections of component A and component B along this direction at least partially overlap. On this basis, component A and component B can be arranged at intervals in this direction, or they can be fitted to each other, which will not be repeated below.

[0071] The hinge cover 20 is mounted on the hinge assembly 10. Specifically, the hinge cover 20 can be covered on the right connecting portion 1022 of the second mounting end 102 of the hinge assembly 10, and the second arc-shaped wall 200 of the hinge cover 20 is fixedly connected to the first arc-shaped wall 100 of the hinge assembly 10. The hinge assembly 10 and the hinge cover 20 together form a receiving cavity (not shown). The receiving cavity is used to receive the signal line 04. In this way, the signal line 04 can extend from the inside of the host part 01 to the inside of the display part 02 via the receiving cavity to achieve signal transmission between the host part 01 and the display part 02.

[0072] In the above-mentioned rotating device 03, firstly, the rotating shaft cover 20 is installed on the rotating shaft assembly 10, rather than on the housing 21 of the display part 02. Therefore, the housing 21 of the display part 02 does not need to reserve installation space, which is conducive to realizing the narrow edge design of the display part 02, improving the beauty and refinement of the notebook computer 1, and at the same time, it will not occupy the internal space of the display part 02. In addition, the rotating shaft assembly 10 and the rotating shaft cover 20 are installed and matched by the fixed connection between the first arc-shaped wall 100 and the second arc-shaped wall 200, which makes full use of the axial space and does not occupy a large radial space. Therefore, the rotating device 03 can be made to look slimmer and more beautiful as a whole, which can also effectively improve the beauty and refinement of the notebook computer 1, and is also more conducive to the thin and light design of the notebook computer 1. Among them, the axial direction in the present application can be, for example, the X-axis direction, and the radial direction can be, for example, the direction perpendicular to the X-axis direction, which will not be repeated below.

[0073] An exemplary fixing method between the rotating shaft assembly 10 and the rotating shaft cover 20 will be further described below with reference to the accompanying drawings.

[0074] In some feasible solutions, the rotating shaft assembly 10 and the rotating shaft cover 20 can be fixedly connected by mutually matching mounting grooves and mounting buckles.

[0075] Figure 4A A three-dimensional diagram of a portion of the structure of the shaft assembly 10 in an embodiment of the present application is shown. Figure 4B A three-dimensional view of the rotating shaft cover 20 in the embodiment of the present application is shown. Figure 4C FIG. 1 is a schematic diagram showing the cooperation between the shaft assembly 10 and the shaft cover 20 in the embodiment of the present application. For the convenience of observation, Figure 4C The dotted lines show some structural features of the display portion 02, and the dotted lines show the structural features that are blocked in the hinge assembly 10 and the hinge cover 20. FIG. 4A to FIG. 4C The first arc-shaped wall 100 is provided with a mounting groove 110. The interior of the mounting groove 110 may be Figure 4A and Figure 4C The second arc-shaped wall 200 is provided with a mounting buckle 210. The mounting buckle 210 is matched with the mounting groove 110 to achieve a fixed connection between the shaft assembly 10 and the shaft cover 20.

[0076] Continue reading FIG. 4A to FIG. 4C In some embodiments of the present application, the mounting groove 110 may include a fixed groove 111 and a sliding groove 112. The fixed groove 111 and the sliding groove 112 are arranged at intervals along the N direction. The mounting buckle 210 may include a fixed buckle 211 and a sliding buckle 212. The fixed buckle 211 and the sliding buckle 212 are arranged at intervals along the N direction.

[0077] The fixing groove 111 and the fixing buckle 211 cooperate with each other. Specifically, the fixing groove 111 can provide the fixing buckle 211 with a limit in the N direction. That is, when the fixing buckle 211 is buckled into the fixing groove 111, the fixing buckle 211 cannot slide in the fixing groove 111 in the N direction.

[0078] The sliding groove 112 cooperates with the sliding buckle 212. Specifically, the sliding groove 112 extends along the N direction and can provide radial limitation for the sliding buckle 212. The sliding buckle 212 is slidably disposed in the sliding groove 112. That is, when the sliding buckle 212 is buckled into the sliding groove 112, the sliding buckle 212 can slide in the N direction in the sliding groove 112, and the sliding buckle 212 cannot slide in the radial direction in the sliding groove 112.

[0079] In some embodiments of the present application, the fixing groove 111 may be provided at an end of the first arc-shaped wall 100 along the N direction, for example, the end 1001. In the N direction, the end 1001 of the first arc-shaped wall 100 is further away from the left connecting portion 1021 than the end 1002. That is, along the N direction, the end 1001 of the first arc-shaped wall 100 is further away from the display portion 02 than the end 1002.

[0080] Accordingly, the fixing buckle 211 can be provided at one end of the second arc-shaped wall 200 along the N direction, for example, the end 2001. In the N direction, the end 2001 of the second arc-shaped wall 200 is further away from the left connecting portion 1021 than the end 2002. That is, along the N direction, the end 2001 of the second arc-shaped wall 200 is further away from the display portion (not shown) than the end 2002.

[0081] In this way, the hinge cover 20 can be prevented from interfering with other components (for example, the display portion 02) during the installation process. The specific installation process will be described later. For details, please refer to Fig.9A and Fig. 9B With reference to the related description, the exemplary arrangement of the fixing groove 111 and the fixing buckle 211 , the sliding groove 112 and the sliding buckle 212 will be further introduced below.

[0082] Continue to refer Figure 4A In some embodiments of the present application, the end 1001 of the first arc-shaped wall 100 may include an elastic arm 113 . The fixing groove 111 is disposed on the elastic arm 113 . Figure 5 FIG. 1 shows a three-dimensional view of the elastic arm 113 in another perspective in the embodiment of the present application. Figure 4A and Figure 5, the elastic arm 113 extends along the N direction. Along the N direction, the elastic arm 113 protrudes relative to the peripheral side wall 120 of the shaft assembly 10. At this time, the central angle corresponding to the first arc-shaped wall 100 is greater than the central angle corresponding to the peripheral side wall 120 of the shaft assembly 10.

[0083] In this way, in the process of buckling the fixing buckle 211 into the fixing groove 111, the elastic arm 113 can more easily produce elastic deformation, so that the fixing buckle 211 can be buckled into the fixing groove 111 more smoothly, effectively reducing the difficulty of buckling between the fixing buckle 211 and the fixing groove 111, and further improving the assembly efficiency.

[0084] In order to further reduce the difficulty of buckling between the fixing buckle 211 and the fixing groove 111, in some embodiments of the present application, a first guide surface is provided on the first arc-shaped wall 100. A second guide surface is provided on the fixing buckle 211. The first guide surface and the second guide surface cooperate to guide the fixing buckle 211 to buckle into the fixing groove 111.

[0085] Specifically, Figure 6 The exemplary structure of the first guide surface 114 and the second guide surface 2111 in the embodiment of the present application is shown. Figure 6 The shaft assembly 10 and the shaft cover 20 are part of the structure along Figure 3A Section view of the AA section. Figure 6 , the first guide surface 114 may be an inclined surface that is inclined away from the second arc-shaped wall 200 relative to the Z-axis direction. The first guide surface 114 is connected to the inner surface of the groove wall of the fixing groove 111, wherein the inner surface of the groove wall of the fixing groove 111 refers to the surface of the groove wall facing the inside of the fixing groove 111. The inclination direction of the second guide surface 2111 is parallel to the inclination direction of the first guide surface 114. Alternatively, it can be said that the plane where the first guide surface 114 is located is parallel to the plane where the second guide surface 2111 is located.

[0086] Continue reading Figure 6 Combined with FIG. 4A to FIG. 4C In the process of buckling the fixing buckle 211 into the fixing groove 111, the first guide surface 114 and the second guide surface 2111 can be first fitted together, and then the shaft cover 20 can be rotated along the N direction so that the second guide surface 2111 slides relative to the first guide surface 114 until the fixing buckle 211 slides into the interior of the fixing groove 111.

[0087] By providing the first guide surface 114 and the second guide surface 2111, the fixing buckle 211 can be more smoothly buckled into the fixing groove 111. Therefore, the first guide surface 114 and the second guide surface 2111 can effectively reduce the buckling difficulty between the fixing buckle 211 and the fixing groove 111, further improving the assembly efficiency.

[0088] Continue to refer Figure 4B In some embodiments of the present application, the end 2001 of the second arc-shaped wall 200 may include an elastic arm 213, and the fixing buckle 211 is disposed on the elastic arm 213. The specific structure of the elastic arm 213 is substantially the same as that of the elastic arm 113, and reference may be made to the above description of the elastic arm 113, which will not be repeated here.

[0089] In this way, in the process of buckling the fixing buckle 211 into the fixing groove 111, the elastic arm 213 can also produce elastic deformation more easily, so that the fixing buckle 211 can be buckled into the fixing groove 111 more smoothly, effectively reducing the difficulty of buckling between the fixing buckle 211 and the fixing groove 111, and further improving the assembly efficiency.

[0090] In order to further improve the strength of the shaft cover 20 , in some embodiments of the present application, the second arc-shaped wall 200 may further include a reinforcement portion. Fig. 7A and Figure 7B FIG. 2 shows an exemplary structure of the reinforcement portion 214 in the second arc-shaped wall 200 in an embodiment of the present application, wherein: Figure 7B For the shaft cover 20 along Fig. 7A Section view of the BB section. Fig. 7A and Figure 7B , the reinforcing portion 214 is similar to an arc shape and extends along the N direction. The reinforcing portion 214 is connected between the peripheral side wall 220 of the rotating shaft cover 20 and the elastic arm 213. In addition, the wall thickness D1 of the reinforcing portion 214 is greater than the wall thickness D2 of the elastic arm 213. The wall thickness D1 of the reinforcing portion 214 can be, for example, the dimension of the reinforcing portion 214 along the X-axis direction, and the wall thickness D2 of the elastic arm 213 can be, for example, the dimension of the elastic arm 213 along the X-axis direction.

[0091] By providing the reinforcing portion 214, the wall thickness of the second arc-shaped wall 200 can be partially increased, thereby further improving the strength of the second arc-shaped wall 200, thereby ensuring the installation reliability of the shaft cover 20. At the same time, the elastic deformation capability of the elastic arm 213 will not be affected, ensuring that the fixing buckle 211 can be smoothly buckled into the fixing groove 111.

[0092] It is understandable that the above Fig. 7A and Figure 7BThe structure of the reinforcing portion 214 is only schematically shown. In some other embodiments, the reinforcing portion 214 may have other structural forms. For example, in some embodiments, the reinforcing portion 214 may also be a plurality of protrusions spaced apart along the N direction, wherein the shape of the protrusions may be a regular shape such as a cylinder, a cuboid, or an irregular shape. For another example, the reinforcing portion 214 may also be two arc-shaped narrow strips spaced apart along the radial direction, and the arc-shaped narrow strips extend along the N direction. The present application does not impose any specific restrictions on this, and any reinforcing portion 214 that can enhance the strength of the second arc-shaped wall 200 is within the protection scope of the present application.

[0093] Figure 8 FIG. 1 shows an exemplary structure of the sliding groove 112 in an embodiment of the present application. Figure 8 The sliding groove 112 includes an upper groove wall 1121 and a lower groove wall 1122 which are arranged opposite to each other in the radial direction. In the radial direction, the upper groove wall 1121 is farther away from the axis L1 than the lower groove wall 1122.

[0094] refer to Figure 8 Combined with FIG. 4A to FIG. 4C In some embodiments of the present application, a notch 1123 is provided on the upper groove wall 1121 of the sliding groove 112. The notch 1123 connects the inside and the outside of the sliding groove 112. The notch 1123 can divide the upper groove wall 1121 into multiple parts that are not connected to each other, such as Figure 8 The first part 1121a and the second part 1121b in the example shown. The sliding buckle 212 can slide into the sliding groove 112 through the notch 1123, thereby further improving the convenience of assembly between the rotating shaft assembly 10 and the rotating shaft cover 20.

[0095] In other embodiments, the notch 1123 may also be provided in the lower groove wall 1122 , and the present application does not impose any specific limitation on this, as long as the engagement between the sliding buckle 212 and the sliding groove 112 can be achieved.

[0096] In some embodiments of the present application, the number of the sliding buckles 212 can be multiple, for example, two, three, four, etc., to further improve the reliability of the connection between the hinge assembly 10 and the hinge cover 20.

[0097] In some implementations, when the number of the sliding buckles 212 is three or more, the plurality of sliding buckles 212 may be arranged at equal intervals along the N direction. In this way, it is possible to ensure that the force between the rotating shaft assembly 10 and the rotating shaft cover 20 is uniform, thereby further improving the reliability of the connection between the rotating shaft assembly 10 and the rotating shaft cover 20.

[0098] In some implementations, multiple sliding buckles 212 can share a sliding slot 112. For example FIG. 4A to FIG. 4CIn the example shown, there are two sliding buckles 212, which are spaced apart in the N direction and share a sliding groove 112. Both sliding buckles 212 can slide in the N direction in the sliding groove 112.

[0099] In some other implementations, there may be multiple sliding slots 112 . The multiple sliding slots 112 correspond to the multiple sliding buckles 212 one by one, and each sliding buckle 212 is slidably disposed in the corresponding sliding slot 112 .

[0100] In some implementations, there may be multiple notches 114 . The multiple notches 114 correspond to the multiple sliding buckles 212 one by one, and each sliding buckle 212 can slide into the sliding slot 112 through the corresponding notch 214 .

[0101] In some embodiments of the present application, the mounting groove 110 and the corresponding mounting buckle 210 can be matched with a small gap. That is, there can be a small gap (for example, a gap of less than 0.1 mm) between each mating surface of the mounting groove 110 and the corresponding mounting buckle 210. For example, there can be a small gap (for example, a gap of less than 0.1 mm) between each mating surface of the fixed groove 111 and the fixed buckle 211, and / or, there can be a small gap (for example, a gap of less than 0.1 mm) between each mating surface of the sliding groove 112 and the sliding buckle 212. Based on this, the mounting buckle 210 can be smoothly buckled into the interior of the corresponding mounting groove 110, and at the same time, it can also prevent the mounting buckle 210 from floating significantly relative to the mounting groove 110 in the N direction and radial direction, thereby ensuring the reliability and stability of the installation of the shaft cover 20.

[0102] Continue reading FIG. 4A to FIG. 4C In some embodiments of the present application, the rotating shaft assembly 10 may be provided with a first stop surface 130. For example, the first stop surface 130 may be a surface of the left connecting portion 1021 facing the rotating shaft cover 20 along the Z-axis direction. The rotating shaft cover 20 may be provided with a second stop surface 230. For example, the second stop surface 230 may be a surface of the rotating shaft cover 20 facing the left connecting portion 1021 along the Z-axis direction. When the rotating shaft cover 20 is installed on the rotating shaft assembly 10, the first stop surface 130 may cooperate with the second stop surface 230, so as to provide the rotating shaft cover 20 with a limit in the N direction, ensuring that the rotating shaft cover 20 will not continue to rotate in the N direction, so that the rotating shaft cover 20 can be kept in the correct position.

[0103] Continue to refer Figure 4A , Figure 4B and Figure 6In some embodiments of the present application, the shaft assembly 10 may further include a third arc-shaped wall 300. Along the X-axis direction, the third arc-shaped wall 300 and the first arc-shaped wall 100 are respectively located at opposite ends of the shaft assembly 10, and are connected through the peripheral side wall 120 of the shaft assembly 10. The shaft cover 20 may further include a fourth arc-shaped wall 400. Along the X-axis direction, the fourth arc-shaped wall 400 and the second arc-shaped wall 200 are respectively located at opposite ends of the shaft cover 20, and are connected through the peripheral side wall 220 of the shaft cover 20.

[0104] The third arc-shaped wall 300 and the fourth arc-shaped wall 400 are arranged opposite to each other along the X-axis direction, and are matched with the fourth arc-shaped wall 400 through the mounting groove and the mounting buckle. That is to say, along the X-axis direction, the arc-shaped walls at the opposite ends of the rotating shaft assembly 10 are matched with the arc-shaped walls at the opposite ends of the rotating shaft cover 20, respectively, so as to realize the fixed connection between the rotating shaft assembly 10 and the rotating shaft cover 20. In this way, the installation reliability between the rotating shaft assembly 10 and the rotating shaft cover 20 can be effectively improved. Among them, the matching mode between the third arc-shaped wall 300 and the fourth arc-shaped wall 400 can be specifically referred to the matching mode between the first arc-shaped wall 100 and the second arc-shaped wall 200, and will not be repeated here.

[0105] The following continues to describe the installation process of the rotating shaft cover 20 in conjunction with the accompanying drawings. It should be noted that the process of the first arc-shaped wall 100 and the second arc-shaped wall 200 being installed in coordination with each other in this embodiment is substantially the same as the process of the third arc-shaped wall 300 and the fourth arc-shaped wall 400 being installed in coordination with each other. To make the description concise, the following mainly describes the installation process of the rotating shaft cover 20 with the first arc-shaped wall 100 and the second arc-shaped wall 200.

[0106] Fig.9A and Fig. 9B FIG. 2 shows an exemplary installation process of the shaft cover 20 in the embodiment of the present application. For the convenience of observation, Fig.9A and Fig. 9B Part of the structural features of the display portion 02 are shown with dotted lines, and the structural features that are blocked in the hinge assembly 10 and the hinge cover 20 are shown with dotted lines.

[0107] refer to Fig.9A First, place the shaft cover 20 close to the shaft assembly 10 so that the fixing groove 111 and the fixing buckle 211 are close to each other. Then move the shaft cover 20 to Fig. 9B As shown in the position, so that the sliding buckle 212 can pass through the gap (for example, the above Figure 8 The notch 1123 in the example shown slides smoothly into the sliding groove 112. Then, the shaft cover 20 is rotated in the direction N1 until the shaft cover 20 is located Figure 4CIn this process, the sliding buckle 212 can slide in the sliding groove 112, and the elastic arm of the rotating shaft assembly 10 (for example, the above Figure 4A The elastic arm 113 in the example shown) and the elastic arm of the shaft cover 20 (for example, the above Figure 4B The elastic arm 213 in the example shown will be elastically deformed until the fixing buckle 111 is buckled into the fixing groove 111, and the first stop surface 130 and the second stop surface 230 are in contact. At this time, the sliding groove 112 provides radial limitation for the sliding buckle 212, thereby preventing the shaft cover 20 from being radially disengaged from the shaft assembly 10; the fixing groove 111 can provide limitation for the fixing buckle 211 in the N direction, and the cooperation between the first stop surface 130 and the second stop surface 230 can also provide limitation for the shaft cover 20 in the N direction, thereby effectively preventing the shaft cover 20 from being disengaged from the shaft assembly 10 in the N direction, and finally completing the installation of the shaft cover 20, as shown in the following figure. Figure 4C The rotating device 03 in the example shown.

[0108] In the above-mentioned rotating device 03, since the rotating shaft cover 20 and the rotating shaft assembly 10 are connected by rotating and buckling, when the rotating shaft cover 20 is assembled to the rotating shaft assembly 10, there is no need to generate relative movement between the rotating shaft cover 20 and the rotating shaft assembly 10 other than the rotation direction (for example, along the Z-axis direction), so it can effectively avoid the rotating shaft cover 20 from interfering with other components during the installation process. For example, in some technical solutions, the display part 02 and the rotating shaft assembly 10 are assembled first, and then the rotating shaft cover 20 is installed. In the process of translating the rotating shaft cover 20 along the Z-axis direction to realize the installation of the rotating shaft cover 20, the rotating shaft cover 20 will interfere with the display part 02, thereby causing the rotating shaft cover 20 to be unable to be installed normally. In the present application, the rotating shaft cover 20 is installed by rotating with the rotating shaft assembly 10 along the N1 direction, so it can effectively avoid the display part 02 from interfering with the installation of the rotating shaft cover 20. This installation method is simple and practical, low cost, and has a wide range of applications.

[0109] It can be understood that in the above embodiment, the fixing groove 111 is provided at the end 1001 of the first arc-shaped wall 100, and the fixing buckle 211 is provided at the end 2001 of the second arc-shaped wall 200, but the present application is not limited thereto. For example, in some alternative implementations, the fixing groove 111 can also be provided at other positions of the first arc-shaped wall 100, for example, the fixing groove 111 can also be provided at the end 1002 of the first arc-shaped wall 100, or the fixing groove 111 can also be provided at the middle part between the end 1001 and the end 1002. Accordingly, the position of the fixing buckle 211 can also be adaptively adjusted as the position of the fixing groove 111 changes, which will not be described in detail here.

[0110] In addition, it can be understood that the above is only an exemplary description of the installation method of the shaft cover 20, and does not constitute a limitation of the present application. In other feasible schemes, the shaft cover 20 can also be installed on the shaft assembly 10 in other ways, and the present application does not make specific restrictions on this, as long as the installation of the shaft cover 20 can be achieved.

[0111] For example, in some other feasible solutions, the first arc-shaped wall 100 may be provided with mounting buckles 210, such as a fixed buckle 211 and a sliding buckle 212. The second arc-shaped wall 200 may be provided with mounting grooves 110, such as a fixed groove 111 and a sliding groove 112. The fixed buckle 211 cooperates with the fixed groove 111, and the sliding buckle 212 cooperates with the sliding groove 112, so as to realize the fixed connection between the rotating shaft assembly 10 and the rotating shaft cover 20.

[0112] For another example, in some other feasible solutions, the mounting groove 110 may include a plurality of fixed grooves 111, but does not include a sliding groove 112. Accordingly, the mounting buckle 210 may include a plurality of fixed buckles 211, but does not include a sliding buckle 212. The plurality of fixed buckles 211 correspond one-to-one to the plurality of fixed grooves 111, and can be buckled into the plurality of fixed grooves 111. Moreover, in addition to being able to provide the corresponding fixed buckle 211 with a limit in the N direction, at least some of the fixed grooves 111 can also provide the corresponding fixed buckle 211 with a limit in the radial direction. In this way, the fixed connection between the shaft assembly 10 and the shaft cover 20 can also be achieved.

[0113] For example, in some other feasible solutions, the first arc-shaped wall 100 and the second arc-shaped wall 200 may be pressed against each other along the X-axis direction; the third arc-shaped wall 300 and the fourth arc-shaped wall 400 may be pressed against each other along the X-axis direction. It can also be understood that the end face of the first arc-shaped wall 100 and the end face of the second arc-shaped wall 200 are interference fit, and the end face of the third arc-shaped wall 300 and the end face of the fourth arc-shaped wall 400 are interference fit. The end face of each arc-shaped wall refers to the surface of each arc-shaped wall that is perpendicular to the X-axis direction. In this way, the shaft assembly 10 and the shaft cover 20 can be pressed against each other along the Z-axis direction, thereby realizing the fixed connection between the shaft assembly 10 and the shaft cover 20.

[0114] For example, in some other feasible schemes, the first arc-shaped wall 100 and the second arc-shaped wall 200 may be pressed against each other in the radial direction. For example, the second arc-shaped wall 200 may be similar to an arc-shaped groove structure, including two groove walls spaced apart in the radial direction, the first arc-shaped wall 100 is located inside the arc-shaped groove structure, and the radial dimension of the arc-shaped groove structure is smaller than the radial dimension of the first arc-shaped wall 100, that is, the circumferential side surface of the first arc-shaped wall 100 and the circumferential side surface of the second arc-shaped wall 200 are interference fit, so that the first arc-shaped wall 100 and the second arc-shaped wall 200 are pressed against each other in the radial direction. Correspondingly, the third arc-shaped wall 300 and the fourth arc-shaped wall 400 may also be pressed against each other in the radial direction, and the specific implementation method thereof may refer to the implementation method of the first arc-shaped wall 100 and the second arc-shaped wall 200 being pressed against each other in the radial direction. In this way, the rotating shaft assembly 10 and the rotating shaft cover 20 can be pressed against each other in the radial direction, thereby achieving a fixed connection between the rotating shaft assembly 10 and the rotating shaft cover 20 .

[0115] In some embodiments of the present application, the material of the shaft cover 20 can be metal or plastic.

[0116] In some implementations, the material of the hinge cover 20 is metal, such as aluminum alloy, stainless steel, titanium alloy, etc. In this way, various appearance effects can be more easily obtained, thereby meeting the appearance design requirements of the notebook computer 1.

[0117] Compared with the above-mentioned hinge cover that is fixed to the shell of the display part by a snap-fit ​​structure, the material of the hinge cover 20 in the rotating device provided by the present application has more choices, so that more different appearance effects can be achieved to meet the appearance design requirements of the laptop computer 1. Specifically, during the installation process of the above-mentioned hinge cover, its snap-fit ​​structure needs to produce a large elastic deformation to be snapped into the shell of the display part. Therefore, the material of the hinge cover needs to be a material that is easy to produce elastic deformation, such as plastic, which will cause the appearance effect of the hinge cover to be relatively simple and have a small scope of application. In the present application, the hinge cover 20 does not need to produce a large elastic deformation during the installation process. Therefore, there are more materials to choose from for the hinge cover 20. For example, in addition to plastic, the material of the hinge cover 20 can also be various metals. In this way, it is easier to obtain various appearance effects, thereby meeting the appearance design requirements of the laptop computer 1.

[0118] In some embodiments of the present application, the rotating shaft cover 20 may be subjected to surface treatment to obtain a desired color effect, so that the appearance of the rotating shaft cover 20 obtained is more refined and beautiful. The surface treatment may include but is not limited to at least one of optical coating, ink spraying, anodizing, and physical vapor deposition (PVD), which is not specifically limited in the present application.

[0119] In some embodiments of the present application, the forming method of the shaft cover 20 may include but is not limited to at least one of stamping, forging, computer numerical control (CNC) machining, metal injection molding (MIM), and injection molding, and the present application does not make specific limitations here.

[0120] The above is an explanation of the implementation mode of the present application by specific specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification.
