Description

Technical Field

[0001] This application relates to the technical field of electronic devices, and particularly to a notebook computer. Background Art

[0002] The connecting device of a notebook computer is a key component connecting the display screen end and the host computer end of the notebook computer. Specifically, the connecting device includes a shaft core and a sleeve. The sleeve is sleeved outside the shaft core, and the sleeve and the shaft core are assembled in an embedded manner. The display screen of the notebook computer is fixedly connected to the sleeve, and the shaft core of the lower cover of the host computer of the notebook computer is fixedly connected, so as to realize the rotational connection between the display screen of the notebook computer and the lower cover of the host computer of the notebook computer.

[0003] However, since the shaft core in the prior art is formed by sleeving multiple components, in order to achieve sufficient structural strength, the diameter of the rotating shaft needs to be relatively large, so that when the screen of the notebook computer is opened, the rotation diameter of the display screen of the notebook computer is relatively large, that is, the display screen of the notebook computer needs to occupy a larger space during the rotation process, resulting in an increase in the overall thickness of the notebook computer; moreover, since the diameter of the rotating shaft is relatively large, when the display screen of the notebook computer is opened and the display screen is flipped by a certain angle, the distance between the display screen and the user becomes farther, resulting in a poor visual experience for the user. Utility Model Content

[0004] This application provides a notebook computer, and proposes a connecting device. The screen rear cover and the host upper cover of the notebook computer are rotationally connected through the connecting device. The connecting device includes a shaft core and at least two brackets. The at least two brackets are respectively rotationally connected to both ends of the shaft core. By making the shaft core an integral structure, while meeting the strength requirements of the shaft core, the diameter of the shaft core can be reduced, so that when the display screen of the notebook computer is in the open state, the position of the screen rear cover is closer to the user, improving the visual experience of the user.

[0005] In a first aspect, the present application provides a laptop computer, including a connecting device, a rear screen cover, and a top cover of the main body. The connecting device includes a shaft core and at least two brackets. The at least two brackets are respectively connected to two ends of the shaft core, and each bracket has a shaft hole. The shaft core includes a first shaft core portion, a first connecting portion, and a second shaft core portion. The first shaft core portion, the first connecting portion, and the second shaft core portion are arranged in sequence and are of an integral structure. The first shaft core portion and the second shaft core portion are respectively rotatably connected to the shaft holes of the at least two brackets. The at least two brackets are fixedly connected to the top cover of the main body, and the first connecting portion is fixedly connected to the rear screen cover. By making the first shaft core portion, the first connecting portion, and the second shaft core portion of an integral structure, while meeting the strength requirements of the shaft core, the diameter of the shaft core can be reduced, so that the distance between the axis of the shaft core and the upper wall surface of the top cover of the main body in the Z direction is smaller. When the display screen of the laptop computer is in the open state, the position of the display screen is closer to the user, improving the user's visual experience.

[0006] In a possible implementation manner, the bracket has a second connecting portion, and the shaft hole is provided on the second connecting portion. The inner wall surface of the top cover of the main body includes an upper wall surface. The direction in which the second connecting portion faces the upper wall surface is the first direction. The second connecting portion has a first outer wall surface in the first direction. The first outer wall surface is a plane, and an opening is provided on the first outer wall surface. The opening is communicated with the shaft hole. The partial height of the second connecting portion in the Z direction is reduced, so that the distance between the axis of the shaft core and the upper wall surface of the top cover of the main body in the Z direction is smaller. When the display screen of the laptop computer is in the open state, the position of the display screen is closer to the user, improving the user's visual experience.

[0007] In a possible implementation manner, the bracket has a second connecting portion, and the shaft hole is provided on the second connecting portion. The inner wall surface of the top cover of the main body includes an upper wall surface. The direction in which the second connecting portion faces the upper wall surface is the first direction. The second connecting portion has a first outer wall surface in the first direction. The first outer wall surface is a plane. The second direction is perpendicular to both the first direction and the axial direction of the shaft hole. The distance between the first outer wall surface and the inner wall of the shaft hole is less than the wall thickness of the shaft hole in the second direction. The partial height of the second connecting portion in the Z direction is reduced, so that the distance between the axis of the shaft core and the upper wall surface of the top cover of the main body along the Z direction is smaller. When the display screen of the laptop computer is in the open state, the position of the display screen is closer to the user, improving the user's visual experience.

[0008] In a possible implementation, the spacing distance between the first outer wall surface and the upper wall surface is in the range of 0.85 mm to 1.1 mm, thereby reducing the distance between the axis of the shaft core in the Z direction and the upper wall surface of the main body upper cover, so that when the display screen of the notebook computer is in the open state, the position of the display screen is closer to the user, improving the user's visual experience.

[0009] In a possible implementation, the perpendicular distance between the axis of the shaft hole and the first outer wall surface is in the range of 0.85 mm to 1.1 mm, thereby reducing the distance between the axis of the shaft core in the Z direction and the upper wall surface of the main body upper cover, so that when the display screen of the notebook computer is in the open state, the position of the display screen is closer to the user, improving the user's visual experience.

[0010] In a possible implementation, the bracket includes a base portion, the base portion is fixedly connected to or integrally formed with the base portion, a first assembly structure is provided on the base portion, and the first assembly structure is used for fixedly connecting with the main body upper cover to realize the fixed connection between the bracket and the main body upper cover.

[0011] In a possible implementation, the second connecting portion has a circumferential enclosing area and a stop area arranged along the axial direction of the shaft hole. The inner wall of the shaft hole in the circumferential enclosing area contacts the outer wall of the shaft core, and there is a first gap between the inner wall of the shaft hole in the stop area and the outer wall of the shaft core. This avoids the shaft core from shaking in the shaft hole, thereby improving the stability when the display screen of the notebook computer switches between the closed state and the open state; at the same time, it avoids a strong collision between the display screen and the main body upper cover, improving the service life of the notebook computer. In addition, the stop area and the shaft core do not directly contact. When the shaft core rotates in the shaft hole of the circumferential enclosing area, the torque of the shaft core will not be transmitted to the stop area, improving the service life of the stop area.

[0012] In a possible implementation, there is a second gap between the circumferential enclosing area and the stop area. The circumferential enclosing area is fixedly connected to or integrally formed with the base portion, and the stop area is fixedly connected to or integrally formed with the base portion. The stop area and the shaft core do not directly contact, so that when a collision occurs between the stop area and the shaft core, the impact force received by the stop area will not be transmitted to the circumferential enclosing area, improving the service life of the circumferential enclosing area; moreover, there is no need to provide an additional connecting structure between the circumferential enclosing area, the stop area and the base portion, reducing the number of parts of the connecting device and simplifying the assembly process of the connecting device, which is beneficial to cost reduction.

[0013] In a possible implementation, one side of the stop area has a reinforcing portion. The reinforcing portion is connected to or integrally formed with the base portion, and the reinforcing portion has a stop surface. The connecting device includes a connecting member, the connecting member is fixedly connected to the first connecting portion, and the connecting member is fixedly connected to the screen rear cover. The connecting member has an abutting surface. When the screen rear cover and the main body upper cover are rotated to a certain angle, the abutting surface abuts against the stop surface. The reinforcing portion enhances the strength of the stop area, enabling the stop area to withstand the impact force when the axis core collides with the stop area during the opening and closing process of the display screen of the notebook computer, improving the structural stability of the bracket, and further improving the structural stability of the connecting device. Moreover, when the abutting surface abuts against the stop surface, the display screen of the notebook computer is opened to the maximum angle. At this time, the display screen of the notebook computer cannot continue to rotate away from the main body upper cover, enhancing the stability of the torsion during the opening and closing process of the display screen of the notebook computer.

[0014] In a possible implementation, the diameters of the first axis core portion and the second axis core portion are both less than or equal to 1.8 millimeters. The first connecting portion includes a third axis core portion and a connecting plate. The first axis core portion, the third axis core portion, and the second axis core portion are arranged in sequence. The connecting plate is located on one side of the third axis core portion, and the diameter of the third axis core portion is within the range of less than or equal to 2.4 millimeters. That is, the overall diameter of the axis core is relatively small, such that when the notebook computer changes from the closed state to the open state, the distance between the display screen and the user is relatively close, which is beneficial to improving the user's visual experience.

[0015] In a possible implementation, the connecting device includes a connecting member. The connecting member is fixedly connected to the connecting portion, and the connecting member has a connecting surface with a fixing adhesive layer thereon, which is used to fixedly connect to the screen rear cover. Compared with connecting the screen rear cover and the connecting member using bolts, the distance between the connecting surface and the surface of the screen rear cover on one side in the Y direction is relatively small. When the thickness of the screen rear cover in the Y direction is constant, it can avoid interference between the display screen and the connecting member, thereby increasing the area of the display screen and improving the user's visual experience.

[0016] In a possible implementation, the maximum thickness of the screen rear cover is less than or equal to 1.5 millimeters. That is, the thickness of the screen rear cover is relatively small, making the overall thickness of the screen rear cover and the display screen relatively small, which is beneficial to reducing the thickness of the notebook computer.

[0017] In a possible implementation manner, the connecting device includes a connecting member, the connecting member includes a rotating shaft portion and a fixing portion, the rotating shaft portion and the fixing portion are fixedly connected, the rotating shaft portion has a shaft cavity, and the shaft core is located in the shaft cavity and fixedly connected to the fixing portion; the cross-section of the rotating shaft portion along the direction perpendicular to the axial direction of the shaft core is in a fan-shaped ring shape, the axis of the rotating shaft portion coincides with the axis of the shaft core, and the outer diameter of the rotating shaft portion is less than or equal to 15 millimeters. This avoids friction between the rotating shaft portion and the shaft core during the rotation of the shaft core, improving the smoothness of the shaft core during rotation; reducing the outer diameter of the rotating shaft portion can increase the length of the screen back cover in the Y direction, thereby increasing the area of the display screen.

[0055] The present application provides a notebook computer 10. Refer to Figure 1 As shown, the notebook computer 10 includes a connecting device 100, a screen rear cover 200, a main body upper cover 300, a display screen 400, and a main body lower cover 500. The connecting device 100 rotatably connects the screen rear cover 200 and the main body upper cover 300 of the notebook computer 10. The screen rear cover 200 and the display screen 400 are fixedly connected, and the screen rear cover 200 is connected to the back of the display screen 400 of the notebook computer 10. The main body upper cover 300 and the main body lower cover 500 are fixedly connected, and the keyboard of the notebook computer 10 is installed on the main body upper cover 300. When the notebook computer 10 is placed on a desktop for use, the main body lower cover 500 is located at the bottom of the notebook computer 10 to support the notebook computer 10. The screen rear cover 200 and the main body upper cover 300 of the notebook computer 10 are rotatably connected through the connecting device 100, that is, the display screen 400 and the main body upper cover 300 of the notebook computer 10 are rotatably connected through the connecting device 100. Refer to Figure 2 and Figure 3 As shown, the display screen 400 of the notebook computer 10 has a closed state and an open state relative to the main body upper cover 300. When the display screen 400 of the notebook computer 10 changes from the closed state to the open state, the screen rear cover 200 rotates in a direction away from the main body upper cover 300, that is, the screen rear cover 200 moves counterclockwise; when the display screen 400 of the notebook computer 10 changes from the open state to the closed state, the screen rear cover 200 rotates in a direction close to the main body upper cover 300, that is, the screen rear cover 200 moves clockwise.

[0056] The laptop computer 10 provided by this application includes a connecting device 100, a screen rear cover 200, and a main machine upper cover 300. The connecting device 100 rotatably connects the screen rear cover 200 and the main machine upper cover 300 of the laptop computer 10.

[0057] This application provides a specific implementation of the connecting device 100 applied to the above laptop computer 10. Refer to Figure 4 and Figure 5 As shown, the connecting device 100 includes a shaft core 110 and at least two brackets 120. The shaft core 110 extends along the X direction, and the at least two brackets 120 are respectively connected to both ends of the shaft core 110 in the X direction. The bracket 120 has a shaft hole 120a, and the shaft core 110 passes through the shaft hole 120a and is rotatably connected to the shaft hole 120a of the bracket 120, so that the shaft core 110 can rotate within the shaft hole 120a.

[0058] In one embodiment, the connecting device 100 includes a shaft core 110 and three brackets 120, where one bracket 120 and the other two brackets 120 are respectively connected to both ends of the shaft core 110 in the X direction.

[0059] Refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, in the embodiment of this application, taking two brackets 120 as an example, the two brackets 120 and the shaft core 110 are accommodated in the main machine upper cover 300. The at least two brackets 120 are fixedly connected to the main machine upper cover 300, and the shaft core 110 is fixedly connected to the screen rear cover 200, so that the screen rear cover 200 and the main machine upper cover 300 are connected through the connecting device 100, and the screen rear cover 200 can rotate relative to the main machine upper cover 300 to open or close the display screen 400 of the laptop computer 10. Specifically, refer to Figure 4 and Figure 5 As shown, the shaft core 110 includes a first shaft core part 111, a first connecting part 112, and a second shaft core part 113. The first shaft core part 111, the first connecting part 112, and the second shaft core part 113 are arranged in sequence and are of an integral structure, that is, the first shaft core part 111 and the second shaft core part 113 are respectively located on both sides of the first connecting part 112, and the first shaft core part 111, the first connecting part 112, and the second shaft core part 113 are arranged in sequence along the X direction. The bracket 120 has a shaft hole 120a. The first shaft core part 111 and the second shaft core part 113 are respectively rotatably connected to the shaft holes 120a of the at least two brackets 120, and the first connecting part 112 is fixedly connected to the screen rear cover 200, so that while the shaft core 110 is rotatably connected to the shaft holes 120a of the at least two brackets 120, it is fixedly connected to the screen rear cover 200, so that when the screen rear cover 200 rotates relative to the main machine upper cover 300, the shaft core 110 rotates within the shaft hole 120a.

[0060] Among them, the integrated structure described in the present application may refer to being formed through a single manufacturing process, that is, the shaft core 110 can be prepared by techniques such as stamping, injection molding, die casting, or hot pressing, or can be manufactured by cutting a casting, rather than being connected by preparing multiple components through screws or snap connections.

[0061] There is no need to provide an additional connection structure between the first shaft core part 111, the first connection part 112, and the second shaft core part 113, which can reduce the diameter of the shaft core 110. At the same time, the shaft core 110 can have a certain strength to ensure the reliability of the shaft core 110 during rotation. Moreover, since the diameter of the shaft core 110 is small, the distance between the axis of the shaft core 110 and the upper wall surface 310 of the main machine upper cover 300 in the Z direction is small, the rotation radius of the screen rear cover 200 is reduced, and the moving distance of the screen rear cover 200 during rotation is small. When the display screen 400 of the notebook computer 10 changes from the closed state to the open state, the position of the display screen 400 is closer to the user, improving the user's visual experience. In addition, by making the first shaft core part 111, the first connection part 112, and the second shaft core part 113 in an integrated structure, compared with the shaft core of the existing non-integrated structure, the number of parts of the connection device 100 is reduced, the assembly process of the connection device 100 is simplified, which is beneficial to cost reduction.

[0062] Taking the display screen 400 of the notebook computer 10 being opened by 120° as an example, refer to Figure 6 and Figure 7 as shown, Figure 6 is a schematic cross-sectional structure diagram of the notebook computer 10 when the diameter of the shaft core 110 is large. At this time, the distance between the axis of the shaft core 110 and the upper wall surface 310 of the main machine upper cover 300 in the Z direction is far. When the display screen 400 of the notebook computer 10 changes from the closed state to the open state, the straight-line distance between the display screen 400 and the surface of the main machine upper cover 300 close to the user is d4; Figure 7 is a schematic cross-sectional structure diagram of the notebook computer 10 when the diameter of the shaft core 110 is small. At this time, the distance between the axis of the shaft core 110 and the upper wall surface 310 of the main machine upper cover 300 in the Z direction is close. When the display screen 400 of the notebook computer 10 changes from the closed state to the open state, the straight-line distance between the display screen 400 and the surface of the main machine upper cover 300 close to the user is d5. In Figure 6 and Figure 7 , the distance between the axis of the shaft core 110 and the side wall of the main machine upper cover 300 on one side in the Y direction is the same.

[0063] It can be clearly observed that when the display screen 400 of the notebook computer 10 changes from the closed state to the open state, d4 is significantly greater than d5, Figure 7 the position of the screen rear cover 200 inFigure 6 The position of the middle screen rear cover 200 is closer to the user, providing a better visual experience for the user. Therefore, in order to enhance the user's visual experience, it is necessary to reduce the diameter of the shaft core 110 and / or reduce the distance between the axis of the shaft core 110 and the upper wall surface 310 of the main body upper cover 300 in the Z direction.

[0064] In one embodiment, the material of the shaft core 110 can be high-strength steel, such as carbon manganese steel, including dual-phase steel, transformation-induced plasticity steel, or 42CrMo forgings, etc.

[0065] In one embodiment, referring to Figure 8 As shown, the laptop 10 includes two connecting devices 100, and the two connecting devices 100 are arranged along the X direction to ensure the connection stability between the screen rear cover 200 and the main body upper cover 300.

[0066] The laptop 10 provided in this application includes a connecting device 100, a screen rear cover 200, and a main body upper cover 300. The connecting device 100 rotatably connects the screen rear cover 200 and the main body upper cover 300 of the laptop 10. The connecting device 100 includes a shaft core 110 and at least two brackets 120. At least two brackets 120 are respectively rotatably connected to both ends of the shaft core 110. The shaft core 110 includes a first shaft core portion 111, a first connecting portion 112, and a second shaft core portion 113 arranged in sequence. By making the first shaft core portion 111, the first connecting portion 112, and the second shaft core portion 113 into an integral structure, while meeting the strength requirements of the shaft core 110, the diameter of the shaft core 110 can be reduced, so that the distance between the axis of the shaft core 110 and the upper wall surface 310 of the main body upper cover 300 in the Z direction is smaller. When the display screen 400 of the laptop 10 changes from the closed state to the open state, the position of the display screen 400 is closer to the user, enhancing the user's visual experience. In addition, compared with the shaft core 110 formed by sleeving multiple components, the number of parts of the connecting device 100 is reduced, the assembly process of the connecting device 100 is simplified, which is beneficial to reducing costs.

[0067] In one possible implementation, referring to Figure 4 and Figure 5 As shown, the bracket 120 has a second connecting portion 121, and the second connecting portion 121 is connected to the shaft core 110. A shaft hole 120a is provided on the second connecting portion 121, so that the shaft core 110 is inserted into the shaft hole 120a to realize the connection between the second connecting portion 121 and the shaft core 110.

[0068] Referring to Figure 2 、 Figure 4 and Figure 5 As shown, the inner wall surface of the main body upper cover 300 includes an upper wall surface 310. The direction in which the second connecting portion 121 faces the upper wall surface 310 is the first direction, and the first direction is Figure 2In the Z direction. The second connecting portion 121 has a first outer wall surface 121a in the first direction. The first outer wall surface 121a is a plane, and an opening 121b is provided on the first outer wall surface 121a. The opening 121b communicates with the shaft hole 120a, so that a part of the height of the second connecting portion 121 in the Z direction is reduced, and thus the distance in the Z direction between the axis of the shaft core 110 and the upper wall surface 310 of the main body upper cover 300 is smaller. When the display screen 400 of the notebook computer 10 is in the open state, the position of the display screen 400 is closer to the user, improving the user's visual experience.

[0069] The second connecting portion 121 is in a sleeve shape, and the cross-section perpendicular to the axial direction is an annular shape. In this embodiment, a part of the second connecting portion 121 facing the upper wall surface 310 can be removed by a turning process, so that a first outer wall surface is formed on one side of the second connecting portion 121 in the Z direction, and the first outer wall surface is a plane. In one embodiment, the removed part of the second connecting portion 121 forms an opening 121b that penetrates the shaft hole 120a on one side of the second connecting portion 121 in the Z direction.

[0070] In one embodiment, referring to Figure 4 and Figure 5 As shown, the first outer wall surface 121a can be parallel to the XY plane, that is, in the Z direction, the first outer wall surface 121a is lower than or equal to the highest point of the shaft core 110.

[0071] It can be understood that the first outer wall surface 121a can be a plane or approximately a plane. Among them, when the first outer wall surface 121a is uneven, it is regarded as the first outer wall surface 121a being approximately a plane.

[0072] In one embodiment, due to the problem of machining process accuracy, the prepared first outer wall surface 121a may not be parallel to the XY plane, that is, in the Z direction, the heights of the first outer wall surface 121a are different. In the Z direction, the first outer wall surface 121a can be lower than or equal to the highest point of the shaft core 110, or a part of the first outer wall surface 121a can be higher than the highest point of the shaft core 110.

[0073] In one possible implementation, referring to Figure 2 and Figure 9 As shown, the bracket 120 has a second connecting portion 121, and the second connecting portion 121 is used to connect with the shaft core 110. A shaft hole 120a is provided on the second connecting portion 121, so that the shaft core 110 is inserted into the shaft hole 120a to realize the connection between the second connecting portion 121 and the shaft core 110. The inner wall surface of the main body upper cover 300 includes an upper wall surface 310. The direction of the second connecting portion 121 facing the upper wall surface 310 is the first direction, and the first direction is Figure 2 the Z direction in

[0074] The second connecting portion 121 has a first outer wall surface 121a in the first direction. The first outer wall surface 121a is a plane. The second direction is perpendicular to both the first direction and the axial direction of the shaft hole 120a. The distance between the first outer wall surface 121a and the inner wall of the shaft hole 120a is less than the wall thickness of the shaft hole 120a in the second direction, so that a partial height of the second connecting portion 121 in the Z direction is reduced. Thus, the distance between the axis of the shaft core 110 and the upper wall surface 310 of the main body upper cover 300 in the Z direction is smaller. When the display screen 400 of the notebook computer 10 is in the open state, the position of the display screen 400 is closer to the user, improving the user's visual experience.

[0075] The second connecting portion 121 is in the shape of a sleeve, and the cross-section perpendicular to the axial direction is an annular shape. In this embodiment, a part of the second connecting portion 121 facing the upper wall surface 310 can be removed by a turning process, so that a first outer wall surface is formed on one side of the second connecting portion 121 in the Z direction, and the first outer wall surface is a plane. In one embodiment, after a part of the second connecting portion 121 is removed, the second connecting portion 121 is still in the shape of a sleeve, and the second connecting portion 121 surrounds the outside of the shaft core 110.

[0076] It can be understood that the first outer wall surface 121a can be a plane or approximately a plane. Among them, when the first outer wall surface 121a is uneven, it is regarded as the first outer wall surface 121a being approximately a plane.

[0077] In one embodiment, the spacing distance between the first outer wall surface 121a and the upper wall surface 310 is in the range of 0.85 mm to 1.1 mm, that is, in the Z direction, the distance between the first outer wall surface 121a and the upper wall surface 310 is in the range of 0.85 mm to 1.1 mm. Refer to Figure 2 As shown, the distance between the first outer wall surface 121a and the upper wall surface 310 is d1, and d1 is in the range of 0.85 mm to 1.1 mm, so that the distance between the axis of the shaft core 110 and the upper wall surface 310 of the main body upper cover 300 in the Z direction is smaller. Thus, when the display screen 400 of the notebook computer 10 is in the open state, the position of the display screen 400 is closer to the user, improving the user's visual experience.

[0078] In one embodiment, the perpendicular distance between the axis of the shaft hole 120a and the first outer wall surface 121a is in the range of 0.85 mm to 1.1 mm, that is, in the Z direction, the distance between the axis of the shaft hole 120a and the first outer wall surface 121a is in the range of 0.85 mm to 1.1 mm. Refer to Figure 14As shown, the distance between the axis of the shaft hole 120a and the first outer wall surface 121a is d2, and d2 ranges from 0.85 mm to 1.1 mm, such that the distance between the axis of the shaft core 110 and the upper wall surface 310 of the main body upper cover 300 in the Z direction can be smaller. Thus, when the display screen 400 of the laptop 10 is in the open state, the position of the display screen 400 is closer to the user, improving the user's visual experience.

[0079] In a possible implementation, refer to Figure 4 and Figure 5 As shown, the bracket 120 includes a base portion 122, and the base portion 122 is fixedly connected to the second connecting portion 121 or is an integral structure. A first assembling structure 122a is provided on the base portion 122, and the first assembling structure 122a is used for fixedly connecting to the main body upper cover 300, thereby realizing the fixed connection between the bracket 120 and the main body upper cover 300.

[0080] In one embodiment, refer to Figure 4 and Figure 5 As shown, the first assembling structure 122a is located on one side of the second connecting portion 121 in the opposite direction of the Z axis. A connecting column is provided on the base portion 122, and the connecting column extends in the opposite direction of the Z axis. The first assembling structure 122a is provided on the connecting column, and the first assembling structure 122a can be a threaded hole. A threaded column corresponding to the first assembling structure 122a is provided on the main body upper cover 300, such that the first assembling structure 122a and the threaded column are threadedly connected.

[0081] In one embodiment, refer to Figure 4 and Figure 5 As shown, a connecting plate extending in the Y direction and in the opposite direction of the X axis is provided on the base portion 122, and connecting holes penetrating the connecting plate in the Z direction are provided on the connecting plate extending in the Y direction and in the opposite direction of the X axis. Correspondingly, a connecting column matching the connecting hole is provided on the main body upper cover 300, or connecting holes are also provided on the main body upper cover 300. The main body upper cover 300 and the connecting plate are connected by rivets or bolts to further ensure the connection stability between the bracket 120 and the main body upper cover 300.

[0082] In a possible implementation, refer to Figure 4 、 Figure 5 、 Figure 13 and Figure 14As shown, the second connecting portion 121 has a circumferential region 1211 and a stop region 1212 arranged along the axial direction of the shaft hole 120a. The inner wall of the shaft hole 120a in the circumferential region 1211 contacts the outer wall of the shaft core 110, preventing the shaft core 110 from wobbling within the shaft hole 120a, thereby enhancing the stability of the display screen 400 of the notebook computer 10 when switching between the closed state and the open state. At the same time, a frictional force can be generated between the inner wall of the shaft hole 120a in the circumferential region 1211 and the outer wall of the shaft core 110. When the display screen 400 of the notebook computer 10 changes from the closed state to the open state, after the external force is removed, the frictional force between the inner wall of the shaft hole 120a in the circumferential region 1211 and the outer wall of the shaft core 110 can overcome the gravity of the display screen 400 of the notebook computer 10, avoiding a strong collision between the display screen 400 and the upper cover 300 of the main body, and improving the service life of the notebook computer 10.

[0083] Refer to Figure 13 and Figure 15 As shown, there is a first gap 130a between the inner wall of the shaft hole 120a in the stop region 1212 and the outer wall of the shaft core 110, such that the stop region 1212 and the shaft core 110 do not come into direct contact. When the shaft core 110 rotates within the shaft hole 120a in the circumferential region 1211, the torque of the shaft core 110 is not transmitted to the stop region 1212, improving the service life of the stop region 1212.

[0084] In a possible implementation, refer to Figure 9 and Figure 10 As shown, there is a second gap 130b between the circumferential region 1211 and the stop region 1212, such that the stop region 1212 and the shaft core 110 do not come into direct contact. When a collision occurs between the stop region 1212 and the shaft core 110, the impact force received by the stop region 1212 is not transmitted to the circumferential region 1211, improving the service life of the circumferential region 1211.

[0085] The circumferential region 1211 and the base portion 122 are fixedly connected or integrally formed, and the stop region 1212 and the base portion 122 are fixedly connected or integrally formed, such that no additional connecting structure needs to be provided between the circumferential region 1211, the stop region 1212, and the base portion 122, reducing the number of parts of the connecting device 100, simplifying the assembly process of the connecting device 100, and being conducive to cost reduction.

[0086] It can be understood that the circumferential region 1211, the stop region 1212, and the base portion 122 are integrally formed and can be prepared by techniques such as stamping, injection molding, die casting, and hot pressing, or can be manufactured by cutting a casting, or can be formed by welding the circumferential region 1211, the stop region 1212, and the base portion 122.

[0087] In a possible implementation, refer to Figure 5 , Figure 10 , Figure 11 and Figure 12 As shown, one side of the stop area 1212 has a reinforcing portion 1213. The reinforcing portion 1213 is connected to or integrally formed with the base portion 122. The reinforcing portion 1213 enhances the strength of the stop area 1212, enabling the stop area 1212 to withstand the impact force when the axis core 110 collides with the stop area 1212 during the opening and closing process of the display screen 400 of the notebook computer 10, improving the structural stability of the bracket 120, and further improving the structural stability of the connecting device 100.

[0088] Refer to Figure 16 , Figure 17 and Figure 18 As shown, the connecting device 100 includes a connecting member 140. The connecting member 140 is fixedly connected to the first connecting portion 112 and fixedly connected to the screen rear cover 200. The connecting member 140 has an abutting surface 141, and the reinforcing portion 1213 has a stop surface 1213a. When the screen rear cover 200 and the main machine upper cover 300 are rotated to a certain angle, the abutting surface 141 abuts against the stop surface 1213a. Among them, when the abutting surface 141 abuts against the stop surface 1213a, the rotation angle of the screen rear cover 200 and the main machine upper cover 300 can be 90°, 100°, 120°, 130°, etc.

[0089] Specifically, when the abutting surface 141 abuts against the stop surface 1213a, the display screen 400 of the notebook computer 10 is opened to the maximum angle. At this time, the display screen 400 of the notebook computer 10 cannot continue to rotate away from the main machine upper cover 300, enhancing the torsional stability during the opening and closing process of the display screen 400 of the notebook computer 10.

[0090] In a possible implementation, refer to Figure 5 As shown, the first connecting portion 112 includes a third axis core portion 112a and a connecting plate 112b. The first axis core portion 111, the third axis core portion 112a, and the second axis core portion 113 are arranged in sequence. The connecting plate 112b is located on one side of the third axis core portion 112a. The first axis core portion 111, the third axis core portion 112a, the second axis core portion 113, and the connecting plate 112b are integrally formed.

[0091] The diameters of both the first shaft core part 111 and the second shaft core part 113 are less than or equal to 1.8 mm, and the diameter of the third shaft core part 112a is less than or equal to 2.4 mm. That is, the overall diameter of the shaft core 110 is relatively small, such that the distance between the axis of the shaft core 110 and the upper wall surface 310 of the main machine upper cover 300 in the Z direction is small, and the moving distance of the screen rear cover 200 during rotation is small. When the notebook computer 10 changes from the closed state to the open state, the straight-line distance between the display screen 400 and the surface of the main machine upper cover 300 close to the user is small, that is, the distance between the display screen 400 and the user in the Y direction is close, which is beneficial to improving the user's visual experience.

[0092] In a possible implementation, referring to Figure 19 and Figure 20 as shown, the connecting device 100 includes a connecting member 140. The connecting member 140 is fixedly connected to the first connecting part 112. The connecting member 140 has a connecting surface 142, and a fixing adhesive layer 143 is provided on the connecting surface 142. The fixing adhesive layer 143 is used for fixedly connecting with the screen rear cover 200, such that the distance between the connecting surface 142 and the surface on one side of the screen rear cover 200 in the Y direction is small. When the thickness of the screen rear cover 200 in the Y direction is constant, it can avoid interference between the display screen 400 and the connecting member 140, thereby increasing the area of the display screen 400 and improving the user's visual experience.

[0093] Referring to Figure 19 and Figure 20 as shown, compared with connecting the screen rear cover 200 and the connecting member 140 by bolts, when the screen rear cover 200 and the connecting member 140 are connected by bolts, the distance between the display screen 400 and the connecting member 140 is small, and interference occurs between the display screen 400 and the connecting member 140, resulting in a small area of the display screen 400; when the screen rear cover 200 and the connecting member 140 are connected by the fixing adhesive layer 143, the distance between the display screen 400 and the connecting member 140 is large, and no interference occurs between the display screen 400 and the connecting member 140, resulting in a large area of the display screen 400.

[0094] In a possible implementation, referring to Figure 20 as shown, the maximum thickness of the screen rear cover 200 is less than or equal to 1.5 mm. The maximum thickness of the screen rear cover 200 is d3, and d3 is less than or equal to 1.5 mm. That is, the thickness of the screen rear cover 200 is small, such that the overall thickness of the screen rear cover 200 and the display screen 400 is small, which is beneficial to reducing the thickness of the notebook computer 10.

[0095] In a possible implementation, referring to Figure 16 、 Figure 17 and Figure 18As shown, the connecting device 100 includes a connecting member 140. The connecting member 140 includes a rotating shaft portion 144 and a fixing portion 145. The rotating shaft portion 144 and the fixing portion 145 are fixedly connected. The rotating shaft portion 144 has a shaft cavity 144a. The shaft core 110 is located within the shaft cavity 144a and is fixedly connected to the fixing portion 145, such that there is a spaced distance between the rotating shaft portion 144 and the shaft core 110. Thus, during the rotation of the shaft core 110, friction between the rotating shaft portion 144 and the shaft core 110 is avoided, improving the smoothness during the rotation of the shaft core 110. Refer to Figure 4 and Figure 17 As shown, the rotating shaft portion 144 and the shaft core 110 are connected by a fastener 146. The fastener 146 can be a screw.

[0096] The cross-section of the rotating shaft portion 144 along a direction perpendicular to the axial direction of the shaft core 110 is in a sector ring shape. The axis of the rotating shaft portion 144 coincides with the axis of the shaft core 110, such that the rotation center of the rotating shaft portion 144 coincides with that of the shaft core 110. During the rotation of the rotating shaft portion 144, the distance between the rotating shaft portion 144 and the shaft core 110 does not change, which is beneficial to ensuring the stability of the connecting device 100 during the opening and closing of the display screen 400 of the notebook computer 10. The outer diameter of the rotating shaft portion 144 is less than or equal to 15 mm, making the volume of the rotating shaft portion 144 smaller. Moreover, reducing the outer diameter of the rotating shaft portion 144 can increase the length of the screen rear cover 200 in the Y direction, thereby increasing the area of the display screen 400.

[0097] In one embodiment, the rotating shaft portion 144 includes a rotating shaft shell 144b and a rotating shaft body 144c. The cross-sections of the rotating shaft shell 144b and the rotating shaft body 144c along a direction perpendicular to the axial direction of the shaft core 110 are both in a sector ring shape. The rotating shaft shell 144b is sleeved outside the rotating shaft body 144c. The rotating shaft shell 144b and the rotating shaft body 144c are detachably connected. The rotating shaft body 144c and the fixing portion 145 are of an integral structure.

[0098] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included within the protection scope of the present application.
