Description

Technical Field

[0001] This invention relates to the field of electronic equipment technology, and more particularly to a rotating hub and an electronic device. Background Technology

[0002] A rotating pivot, also known as a damped hinge or damped shaft, is a connecting element that provides mutual rotation. It is mainly used between rotating parts and the base. Currently, it is widely used in various digital products and electronic devices, such as laptops. The mutual rotation function of the rotating pivot can realize the opening and closing function between the base of the laptop and the display screen to adjust the angle of the laptop relative to the human body.

[0003] Taking laptops as an example, the rotating hinge is usually mounted on the edge of the base and the top cover. However, with the development of laptops becoming thinner and more full-screen, some laptops have a thinner base, which means that when the laptop is placed on a table, the distance between the top cover and the table is relatively close. After the top cover is opened to a certain angle, its edge may touch the table, affecting the smoothness of opening and potentially causing wear and tear on the top cover. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to address the issue that when the substrate of an electronic device is thin, the edge of the top cover may abut against the table after being opened at a certain angle, affecting the smoothness of opening and potentially causing wear and damage to the top cover.

[0005] Therefore, according to a first aspect, the present invention provides a rotating hub, comprising: a hub frame; a first shaft and a second shaft, arranged parallel to each other and rotatably supported by the hub frame; the first shaft and the second shaft are linked by a gear structure, the second shaft having a helical groove; a lifting mechanism, comprising a lifting seat and a guide rod, the lifting seat having a guide groove, the guide rod being disposed in the guide groove and sliding within the guide groove, and the sliding direction of the guide rod within the guide groove having an acute angle with the axial direction of the second shaft; a sleeve being provided at the end of the guide rod extending outside the lifting seat and sleeved on the second shaft, and a guide block corresponding to the helical groove being provided inside the sleeve.

[0006] Furthermore, the guide groove includes a first end near the bottom surface of the lifting seat and a second end away from the bottom surface of the lifting seat; the first end of the guide groove is an inclined portion, the second end of the guide groove is a horizontal portion, the sliding direction of the guide rod in the inclined portion is at an acute angle with the axial direction of the second shaft, and the sliding direction in the horizontal portion is the same as the axial direction of the second shaft.

[0007] Furthermore, there are two guide rods and two guide slots.

[0008] Furthermore, the lifting mechanism also includes a fixing member, which is located at the end of the guide rod away from the second shaft to fix the two guide rods together.

[0009] Furthermore, the lifting seat is provided with a first clearance groove corresponding to the fixing component.

[0010] Furthermore, the first shaft and the second shaft rotate in opposite directions, and the gear structure includes a first gear disposed on the first shaft and a second gear disposed on the second shaft, wherein the number of teeth of the second gear is greater than the number of teeth of the first gear.

[0011] Furthermore, the pivot frame is provided with a second clearance groove corresponding to the second gear.

[0012] Furthermore, it also includes at least one connector, with both the first shaft and the second shaft passing through the connector and rotatable within the connector.

[0013] According to a second aspect, the present invention provides an electronic device comprising: two rotating hubs as described in the first aspect above; a top cover connected to a first shaft in the rotating hub; a base connected to a hub frame in the rotating hub; and a lifting groove corresponding to a lifting seat provided on the base, the bottom surface of the lifting seat protruding from the bottom surface of the base through the lifting groove; when the top cover and the base are closed, the lifting seat protrudes from the bottom surface of the base by a first height, and when the top cover is opened, the height of the lifting seat protruding from the bottom surface of the base gradually increases until it reaches a second height.

[0014] The technical solution provided by this invention has the following advantages:

[0015] The rotary pivot provided by this invention, by setting a first shaft and a second shaft linked together, causes the second shaft to rotate simultaneously via a gear structure when the first shaft rotates. Furthermore, by providing a helical groove on the second shaft and a guide rod with a sleeve at its end and a guide block corresponding to the helical groove inside the sleeve, the rotation of the second shaft is converted into movement of the guide rod (along the axial direction of the second shaft) via the helical groove and the guide block. Finally, by providing a lifting seat with a guide groove, the guide rod can slide within the guide groove, and the sliding direction of the guide rod within the guide groove forms an acute angle with the axial direction of the second shaft, thereby allowing the guide rod to move along the axial direction of the second shaft via... The trajectory of the guide groove causes the movement of the lifting seat (vertical to the second axis); that is, when the electronic device equipped with the rotating hub is opening and closing its top cover, the lifting seat in the rotating hub moves up and down, so that the lifting seat can act as a height-adjustable foot pad for the electronic device, and when the electronic device is opened, it lowers and protrudes from the bottom surface of the electronic device to prevent the top cover from hitting the table, thus preventing the smoothness of opening the top cover and preventing wear and damage to the top cover; at the same time, when the electronic device is closed, the lifting seat rises, and its protrusion relative to the bottom surface of the electronic device is reduced, so it will not affect the thinness of the electronic device.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] Please refer to Figures 1-7 This application discloses an electronic device comprising: two rotating hubs 3, a base 2, and a top cover 1, the top cover 1 being rotatable relative to the base 2 via the two rotating hubs 3. The two rotating hubs 3 are symmetrically arranged on both sides of the electronic device, but their structures are identical; therefore, only one rotating hub 3 will be described below.

[0043] For details, please refer to Figures 3-7 The aforementioned rotating hub 3 includes: a hub frame 31, a first shaft 32, a second shaft 33, a gear structure 34, and a lifting mechanism 35. The upper cover 1 of the electronic device is connected to the first shaft 32, and the base 2 is connected to the hub frame 31. Based on the following, the lifting seat 351 has an upward or downward movement, and its main function is to serve as a foot pad for the electronic device. Therefore, the base 2 of the electronic device has a lifting groove corresponding to the lifting seat 351. The bottom surface of the lifting seat 351 protrudes from the bottom surface of the base 2 through the lifting groove. When the upper cover 1 and the base 2 are closed, the lifting seat 351 protrudes from the bottom surface of the base 2 by a first height. When the upper cover 1 is open, the height of the lifting seat 351 protruding from the bottom surface of the base 2 gradually increases until it reaches a second height.

[0044] Specifically, such as Figures 3-5 As shown, the first shaft 32 and the second shaft 33 are arranged parallel to each other and rotatably supported by the pivot frame 31, and the first shaft 32 and the second shaft 33 are linked by a gear structure 34. Specifically, the first shaft 32 and the second shaft 33 can rotate in opposite directions through the gear structure 34, that is, the first shaft 32 and the second shaft 33 are linked by an even number of gears, such as... Figures 3-5 In this configuration, the first shaft 32 and the second shaft 33 are linked by two gears; alternatively, the first shaft 32 and the second shaft 33 can also rotate in the same direction via a gear structure 34, in which case the first shaft 32 and the second shaft 33 are linked by an odd number of gears. Furthermore, the first shaft 32 and the second shaft 33 can rotate synchronously or asynchronously (the second shaft 33 may accelerate or decelerate relative to the first shaft 32), as shown below. Figures 3-5 In this example, the second shaft 33 is shown rotating at reduced speed relative to the first shaft 32. Figures 3-5 As shown, the gear structure 34 includes a first gear 341 disposed on a first shaft 32 and a second gear 342 disposed on a second shaft 33, wherein the number of teeth of the second gear 342 is greater than the number of teeth of the first gear 341.

[0045] Please refer to Figure 3 and Figure 4 The second shaft 33 also has spiral grooves 331. Specifically, the number of spiral grooves 331 corresponds to the number of guide rods 352 described below. When the guide rods 352 are... Figures 3-5 When there are two as shown, there are also two spiral grooves 331.

[0046] Please refer to Figures 3-7The lifting mechanism 35 includes a lifting seat 351 and a guide rod 352. The lifting seat 351 is provided with a guide groove 3511. The guide rod 352 is disposed in the guide groove 3511 and can slide in the guide groove 3511. The sliding direction of the guide rod 352 in the guide groove 3511 has an acute angle with the axial direction of the second shaft 33. The end of the guide rod 352 extending outside the lifting seat 351 is provided with a sleeve 3522 and sleeved on the outside of the second shaft 33. The sleeve 3521 is provided with a guide block 3521 corresponding to the spiral groove 331.

[0047] In this application, in order to improve the stability of the entire rotating hub 3 when the first shaft 32 rotates to its maximum angle, especially the stability of the descent height of the lifting seat 351, that is, to improve the support stability of the lifting seat 351 as a foot pad when the upper cover 1 in the electronic device is opened to its maximum angle, such as Figures 4-6 As shown, if the end of the guide groove 3511 near the bottom surface of the lifting seat 351 is taken as the first end, and the end away from the bottom surface of the lifting seat 351 is taken as the second end, then the first end of the guide groove 3511 can be set as an inclined portion 3511a, and the second end as a horizontal portion 3511b. The angle between the sliding direction of the guide rod 352 in the inclined portion 3511a and the axial direction of the second shaft 33 is an acute angle, and the sliding direction in the horizontal portion 3511b is the same as the axial direction of the second shaft 33. Thus, when the first shaft 32 rotates to its maximum angle, the guide rod 352 slides to the horizontal portion 3511b of the guide groove 3511 to reach a stable state (e.g., Figure 5 (As shown).

[0048] In this application, when the guide rod 352 is Figures 3-5 In the two cases shown (where there are two guide grooves 3511 and two spiral grooves 331), a fixing member 353 can be provided at the end of the guide rod 352 away from the second shaft 33 to fix the two guide rods 352. Meanwhile, to prevent the fixing member 353 from affecting the height of the entire rotating hub 3, as shown... Figure 4 and Figure 6 As shown, a first clearance groove 3512 corresponding to the fixing member 353 can also be provided on the lifting seat 351. Similarly, when the second gear 342 provided on the second shaft 33 is large, a second clearance groove 311 corresponding to the second gear 342 can be provided on the pivot frame 31.

[0049] In this application, in order to further improve the stability of the entire rotating hub 3, in addition to the hub frame 31 supporting the first shaft 32 and the second shaft 33, at least one connector 36 can be provided between the first shaft 32 and the second shaft 33. The first shaft 32 and the second shaft 33 are both inserted into the connector 36 and can rotate within the connector 36.

[0050] In this application, in order for the upper cover 1 connected to the first shaft 32 to be able to stop freely during rotation, such as Figure 3 As shown, a torque unit 37 can also be provided on the first shaft 32 and the second shaft 33.

[0051] The rotating hub 3 in this application is configured with a first shaft 32 and a second shaft 33 linked together, so that when the first shaft 32 rotates, the second shaft 33 is also rotated via a gear structure 34. Furthermore, the second shaft 33 has a helical groove 331 and a guide rod 352 with a sleeve 3522 at its end and a guide block 3521 corresponding to the helical groove 331 inside the sleeve 3522. This allows the rotation of the second shaft 33 to be converted into movement of the guide rod 352 (along the axial direction of the second shaft 33) via the helical groove 331 and the guide block 3521. Finally, a lifting seat 351 has a guide groove 3511 inside, allowing the guide rod 352 to slide within the guide groove 3511. The sliding direction of the guide rod 352 within the guide groove 3511 forms an acute angle with the axial direction of the second shaft 33. The angle causes the guide rod 352 to move along the axial direction of the second shaft 33, which in turn causes the lifting seat 351 (perpendicular to the axial direction of the second shaft 33) to move via the trajectory of the guide groove 3511. This means that during the opening and closing of the electronic device equipped with the rotating hub 3, the lifting seat 351 in the rotating hub 3 moves up and down, allowing the lifting seat 351 to act as a height-adjustable footpad for the electronic device. When the electronic device is opened, it lowers and protrudes from the bottom surface of the electronic device, preventing the top cover 1 from easily contacting the tabletop, thus preventing any impact on the smoothness of opening the top cover 1 and preventing wear damage to the top cover 1. Simultaneously, when the electronic device is closed, the lifting seat 351 rises, reducing its protrusion relative to the bottom surface of the electronic device, thus not affecting the thinness and lightness of the electronic device.

[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
