TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic equipment, and in particular to a lifting hinge and an electronic device. BACKGROUND

[0002] The hinge device is also called a rotary hinge, a damping hinge or a damping shaft core, and is a connecting element capable of providing a mutual rotation function. The hinge device is mainly applied between a rotating part and a base, and is currently widely applied in various digital products and electronic devices, such as a notebook computer. The mutual rotation function of the hinge device can be used to realize the opening and closing function between the base and the display screen of the notebook computer, so as to adjust the angle required by the notebook computer relative to the human body.

[0003] Taking the notebook computer as an example, the hinge device is usually assembled at the edge position of the base and the upper cover. However, with the development of thinness and full-screen of the notebook computer, the base of some notebook computers is relatively thin, that is, the distance between the upper cover and the desktop is relatively close when the notebook computer is placed on the desktop. After the upper cover is opened to a certain angle, the edge of the upper cover may be in contact with the desktop, which affects the opening fluency and may cause damage to the upper cover. SUMMARY

[0004] Therefore, the technical problem to be solved by the present application is to solve the problem that when the base of the electronic device is relatively thin, the edge of the upper cover may be in contact with the desktop after the upper cover is opened to a certain angle, which affects the opening fluency and may cause damage to the upper cover.

[0005] To this end, according to a first aspect, the present application provides a lifting hinge, comprising:

[0006] A first driving wheel is arranged on the bearing and rotates synchronously with the bearing.

[0007] A second driving wheel is engaged with the first driving wheel, and a connecting rod is fixedly arranged on the second driving wheel.

[0008] A lifting assembly comprises a fixed part and a lifting part rotationally connected with the fixed part. The lifting part has a sliding rail corresponding to the connecting rod. Under the driving of the bearing, the end of the connecting rod away from the second driving wheel can slide in the sliding rail, and the lifting part is driven to rotate and lift relative to the fixed part.

[0009] Further, the second driving wheel has a gear portion and a circumferential portion, and the connecting rod is formed by extending the circumferential portion outward.

[0010] Further, one end of the fixed part is sleeved outside the bearing, and the bearing can rotate in the fixed part; and the other end of the fixed part is rotationally connected with the lifting part.

[0011] Further, the second driving wheel is rotationally connected to the fixed part.

[0012] Further, the lifting rotating shaft further comprises:

[0013] The torsion adjusting assembly is sleeved outside the bearing, and comprises a first concave-convex wheel and a second concave-convex wheel.

[0014] Further, the bearing is provided with a first limiting piece, and the fixed part is provided with a second limiting piece corresponding to the first limiting piece.

[0015] Further, when the bearing rotates to the preset angle, the connecting rod slides to the top end of the slide rail, and the lifting part reaches the maximum lifting height.

[0016] Further, the fixed part has two, and the first driving wheel, the second driving wheel and the lifting part are arranged between the two fixed parts.

[0017] According to the second aspect, the application provides an electronic device comprising:

[0018] Two lifting rotating shafts according to the first aspect;

[0019] The upper cover is connected with the bearing in the lifting rotating shaft.

[0020] The base body is connected with the fixed part in the lifting rotating shaft, and the base body is provided with a lifting groove corresponding to the lifting part.

[0021] The technical scheme provided by the application has the following advantages:

[0022] 1. The lifting rotating shaft provided by the present application, by setting the first driving wheel and the second driving wheel in engagement, and the connecting rod fixedly connected to the second driving wheel, the rotation of the bearing can be converted into the rotation of the connecting rod, and then through the sliding connection of the connecting rod and the lifting piece, and the rotating connection of the lifting piece and the fixed piece, the rotating drive of the bearing is finally converted into the lifting of the lifting piece; that is, the electronic device equipped with the lifting rotating shaft can lift the lifting piece during the opening and closing of the upper cover, so that the lifting piece can serve as a liftable foot pad of the electronic device, and can protrude from the bottom surface of the electronic device when the electronic device is opened, avoiding the influence of the edge of the upper cover on the smoothness of the opening of the upper cover, and preventing damage to the upper cover; at the same time, the lifting piece descends when the electronic device is closed, and the protrusion amount of the lifting piece relative to the bottom surface of the electronic device is reduced, so that the thinness of the electronic device is not affected.

[0023] 2. The lifting rotating shaft provided by the present application, by setting the first concave-convex cam in the torsion adjusting assembly in direct fixed connection with the fixed piece, instead of setting a fixed piece for the first concave-convex cam, the compactness of the structure of the lifting rotating shaft can be improved, the volume thereof can be reduced, and the portability thereof can be improved; by setting the torsion adjusting assembly to include the first concave-convex cam and the second concave-convex cam in cooperation, and setting the torsion assembly abutting against the second concave-convex cam, the torsion assembly can provide a larger second torsion when the convex part of the second concave-convex cam abuts against the convex part of the first concave-convex cam, meeting the torsion requirement when the rotating shaft bearing rotates.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0044] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "linking" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal connection of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0046] The present application discloses an electronic device, such as Figure 1 As shown in the figure, it comprises two lifting shafts 3, a base body 2 and an upper cover 1, the upper cover 1 can be rotated relative to the base body 2 through the two lifting shafts 3. The two lifting shafts 3 are symmetrically arranged on the two sides of the electronic device, but their structures are the same, therefore, only one lifting shaft 3 will be specifically described below.

[0047] Specifically, please refer to Figures 3-6 The lifting shaft 3 comprises a bearing 31, a first driving wheel 32, a second driving wheel 33 and a lifting assembly. Among them, the upper cover 1 in the electronic device is connected with the bearing 31, the base body 2 is connected with a fixing piece 351, and based on the following content, the lifting piece 352 has an active state of lifting (here, lifting refers to the increase of the protruding height of the lifting piece 352 relative to the bottom surface of the base body 2) or descending (here, descending refers to the decrease of the protruding height of the lifting piece 352 relative to the bottom surface of the base body 2), and its function is mainly as a foot pad of the electronic device, therefore the base body 2 of the electronic device has a lifting groove corresponding to the lifting piece 352, and the bottom surface of the lifting piece 352 protrudes from the bottom surface of the base body 2 through the lifting groove; when the upper cover 1 is closed, the lifting piece 352 protrudes from the bottom surface of the base body 2 by a first height, and when the upper cover 1 is opened, the height of the lifting piece 352 protruding from the bottom surface of the base body 2 gradually increases until it reaches a second height.

[0048] Specifically, as shown in the figure, Figures 2-6 The first driving wheel 32 is arranged on the bearing 31 and rotates synchronously with the bearing 31, and the second driving wheel 33 is engaged with the first driving wheel 32. In the present application, the second driving wheel 33 can be arranged on the fixing piece 351 as shown in the figure, of course, it can also be arranged on an independent fixed gear seat. Figure 3

[0049] Specifically, as shown in the figure, Figures 2-6 ​As shown, the second driving wheel 33 is fixedly provided with a connecting rod 34. In the present application, the connecting rod 34 can be arranged at the end of the second driving wheel 33 and synchronously rotate with the second driving wheel 33, or be fixed to the side of the second driving wheel 33. Specifically, based on the maximum rotation angle of the bearing 31 being less than 180 degrees (for example, 135 degrees as shown in Figure 4 and Figure 6 ), thus the side of the second driving wheel 33 can not be entirely provided with the toothed portion, but can include the toothed portion and a circumferential portion, and the connecting rod 34 can be formed by extending outward from the circumferential portion.

[0050] Specifically, as shown in Figure 2 and Figure 3 , the lifting assembly includes a fixed part 351 and a lifting part 352 rotationally connected to the fixed part 351, and the lifting part 352 is provided with a sliding rail 3521 corresponding to the connecting rod 34. Under the driving of the bearing 31, the end of the connecting rod 34 away from the second driving wheel 33 can slide in the sliding rail 3521, and drive the lifting part 352 to rotate and lift relative to the fixed part 351. In the present application, as shown in Figure 3 and Figure 4 , the end of the connecting rod 34 away from the second driving wheel 33 is provided with a sliding block, and the sliding block slides in the sliding rail 3521 when the connecting rod 34 rotates.

[0051] In the present application, in order to improve the smoothness of the end of the connecting rod 34 sliding in the sliding rail 3521, that is, to improve the lifting smoothness of the lifting part 352, as shown in Figure 3 and Figure 4 , the sliding rail 3521 can be arranged as an arc-shaped track. Of course, based on the need to convert the rotation of the connecting rod 34 into the rotation of the lifting part 352 in the present application, the track of the arc-shaped track is different from the rotation track of the connecting rod 34.

[0052] In the present application, in order to improve the structural compactness of the entire lifting shaft 3, as shown in Figure 2 and Figure 4 , one end of the fixed part 351 can be arranged to be sleeved outside the bearing 31, and the bearing 31 can rotate in the fixed part 351. At this time, the lifting part 352 is rotationally connected to the other end of the fixed part 351, and the second driving wheel 33 can also be arranged on the fixed part 351. In addition, in order to improve the connection stability of the lifting part 352 and the fixed part 351, as shown in Figures 2-4 , the fixed part 351 can also be provided as two, and the first driving wheel 32, the second driving wheel 33 and the lifting part 352 are arranged between the two fixed parts 351.

[0053] In the application, when the bearing 31 rotates, the second driving wheel 33 is always in engagement with the first driving wheel 32, that is, when the bearing 31 rotates to the maximum rotation angle (that is, the preset angle), the connecting rod 34 slides to the top end of the slide rail 3521, and the lifting piece 352 reaches the maximum lifting height. The maximum rotation angle of the bearing 31 can be limited by setting the track length of the slide rail 3521, as shown in Figure 5 When the bearing 31 is in the initial non-rotating state, the end of the connecting rod 34 away from the second driving wheel 33 (specifically, the sliding block on the connecting rod 34) is located at the first end of the slide rail 3521, as shown in Figure 6 When the bearing 31 rotates to the maximum rotation angle (that is, the preset angle), the sliding block is located at the second end of the slide rail 3521.

[0054] In the application, when the bearing 31 rotates, the second driving wheel 33 is always in engagement with the first driving wheel 32, that is, when the bearing 31 rotates to the maximum rotation angle (that is, the preset angle), the connecting rod 34 slides to the top end of the slide rail 3521, and the lifting piece 352 reaches the maximum lifting height. The maximum rotation angle of the bearing 31 can be limited by setting the track length of the slide rail 3521, as shown in Figure 3 and Figure 4 When the bearing 31 rotates, the first driving wheel 32 and the second driving wheel 33 are in engagement or idling, a first limiting piece 311 can be arranged on the bearing 31, and a second limiting piece 3511 corresponding to the first limiting piece 311 can be arranged on the fixed piece 351, so that when the bearing 31 rotates to the preset angle, the first limiting piece 311 abuts against the second limiting piece 3511 to limit the continuous rotation of the bearing 31.

[0055] In the application, in order to meet the variable torque requirement of the lifting rotating shaft 3 in a specific application scenario, as shown in Figures 2-4 The lifting rotating shaft 3 further comprises a torque adjusting assembly arranged on the bearing 31. Specifically, the torque adjusting assembly comprises a first concave-convex wheel 361 and a second concave-convex wheel 362. The first concave-convex wheel 361 is fixedly connected with the fixed piece 351, and the second concave-convex wheel 362 rotates synchronously with the bearing 31 and abuts against the torque assembly 37. The torque assembly 37 has a first torque generated when the convex part of the second concave-convex wheel 362 abuts against the concave part of the first concave-convex wheel 361, and a second torque generated when the convex part of the second concave-convex wheel 362 abuts against the convex part of the first concave-convex wheel 361. In the application, the first concave-convex wheel 361 in the torque adjusting assembly is directly fixedly connected with the fixed piece 351, instead of arranging a separate fixed piece 351 for the first concave-convex wheel 361, which can improve the compactness of the structure of the lifting rotating shaft 3, reduce the volume, and improve the portability.

[0056] The lifting rotating shaft 3 in the application, through setting the first driving wheel 32 and the second driving wheel 33 engaged with each other and the connecting rod 34 fixedly connected to the second driving wheel 33, can make the rotation of the bearing 31 be converted into the rotation of the connecting rod 34, and then through the sliding connection between the connecting rod 34 and the lifting piece 352 and the rotating connection between the lifting piece 352 and the fixed piece 351, make the rotation of the bearing 31 be finally converted into the lifting of the lifting piece 352; that is, the electronic device equipped with the lifting rotating shaft 3 can make the lifting piece 352 lift and descend during the opening and closing of the upper cover 1, so that the lifting piece 352 can be used as the liftable foot pad of the electronic device, and make it lift and protrude from the bottom surface of the electronic device when the electronic device is opened, so as to avoid the edge of the upper cover 1 abutting against the desktop and affecting the opening fluency of the upper cover 1, and prevent the abrasion damage to the upper cover 1; at the same time, the lifting piece 352 can descend when the electronic device is closed, and the protruding amount of the lifting piece 352 relative to the bottom surface of the electronic device is reduced, so as not to affect the thinness of the electronic device.

[0057] Obviously, the above embodiments are merely exemplary and are not intended to limit the implementation. Based on the above description, those skilled in the art can make other different forms of changes or modifications. Here, it is not necessary and impossible to enumerate all the implementations. The obvious changes or modifications derived therefrom are still within the protection scope of the application.
