Technical Field
[0001] The present invention relates to the technical field of electronic equipment, and in particular to a hinge structure and an electronic equipment. Background Art
[0002] Generally, foldable dual-screen electronic devices, such as notebook computers, tablet computers or mobile phones, are mainly connected to the first plate body, the second plate body and the auxiliary screen of the electronic device through hinges. Among them, the first plate body can be the upper cover for installing the display screen, and the second plate body can be the base for installing components, batteries and keyboards. The auxiliary screen is generally installed above the second plate body and parallel to the second plate body. In the prior art, electronic devices with auxiliary screens are covered by the first plate body when folded, and the related functions of the auxiliary screen can only be used in the unfolded state. In the unfolded state, the angle is parallel to the second body, which is inconvenient for users to view and use, and it is impossible to adjust the angle of the auxiliary screen as the whole machine is folded or unfolded, so that the auxiliary screen can be conveniently used in both states. Summary of the invention
[0003] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the hinge structure in the prior art cannot adjust the angle of the auxiliary screen, resulting in the auxiliary screen being unable to be conveniently used in both the folded or unfolded state, and to provide a hinge structure and an electronic device.

[0005] Furthermore, the sliding rod is arranged on the sliding limiter, and the sliding groove is arranged on the rotating part.
[0006] Furthermore, the other end of the sliding rod is connected to the hinge bracket; there can be one or more sliding rods.
[0007] Furthermore, a stopper is provided on the rotating shaft, and a stopper block is correspondingly provided on the hinge bracket, and the stopper cooperates with the stopper block to limit the rotation angle of the rotating shaft.
[0008] Furthermore, one end of the axis of the second gear is connected to the sliding limiter, and the other end passes through the rotating part and is connected to the hinge bracket. The second gear is rotatably supported by the sliding limiter and the hinge bracket.
[0009] Furthermore, a torque portion is provided at one end of the rotating shaft.
[0010] Furthermore, the torque part includes a nut, a gasket and a spring sheet; the nut is arranged at one end of the rotating shaft, a gasket is arranged between the nut and the spring sheet, and a gasket is arranged between the sliding limiter and the spring sheet.

[0039] In addition, 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.
[0040] Please refer to Figure 1-Figure 7The present application discloses an electronic device, which includes a first body 6, a second body 7, a third body 8 and a hinge structure, wherein the first body 6 is detachably connected to the mounting portion 21 in the hinge structure, the second body 7 is connected to the hinge bracket 1 in the hinge structure, and the third body 8 is connected to the rotating portion 31 of the hinge structure. When the electronic device is unfolded or folded, the first body 6 drives the third body 8 to rotate in the opposite direction through the hinge structure. The angle of the third body 8 is adjustable, and it will not be covered by the first body 6 when the electronic device is folded. In the unfolded state, it is at a certain angle with the second body 7, which is convenient for users to view, so that the third body 8 can be conveniently used in both the unfolded and folded states of the electronic device.
[0041] Please refer to Figure 1-Figure 5 , is the hinge structure disclosed in this application, and the hinge structure device includes: a hinge bracket 1, a rotating shaft 2, a rotating component 3, a sliding limiter 4 and a torque part 5.
[0042] Please refer to Figure 2-Figure 5 The rotating shaft 2 passes through the through hole on the hinge bracket 1 and is rotatably supported by the hinge bracket 1. A stop portion 23 is provided on the rotating shaft 2, and a stop block 11 is correspondingly provided on the hinge bracket 1. The stop portion 23 includes a first stop surface and a second stop surface. The two side surfaces of the stop block 11 respectively cooperate with the first stop surface and the second stop surface. When the electronic device is in a folded state, the first stop surface contacts one side surface of the stop block 11. When the electronic device is unfolded, the second stop surface cooperates with the other side surface of the stop block 11 to limit the rotation angle of the rotating shaft 2.
[0043] The rotating shaft 2 passes through the hinge bracket 1 and is provided with a rotating assembly 3 on one side. The rotating assembly 3 includes a rotating part 31 and a second gear 32. The rotating shaft 2 passes through the through hole on the rotating part 31. The first gear 22 on the rotating shaft 2 meshes with the second gear 32 to rotate. The second gear 32 is rotatably supported by the hinge bracket 1. A cavity that can accommodate the first gear 22 and the second gear 32 is formed in the rotating part 31. The cavity wall part in the rotating part 31 is provided with an inner tooth 311 meshed with the second gear 32. When the first gear 22 rotates, the second gear 32 is driven to rotate in the opposite direction. The second gear 32 drives the rotating part 31 to rotate in the same direction as the second gear 32, that is, the rotating part 31 rotates in the opposite direction with the first gear 22, so that when the electronic device is unfolded or folded, the first body 6 and the third body 8 rotate in the opposite direction, so that the third body 8 will not be covered by the first body 6 when the electronic device is folded. When the electronic device is unfolded, the third body 8 and the second body 7 are at a certain angle, which is convenient for users to check, so that the electronic device can use the third body 8 in both unfolded and folded states.
[0044] Please refer to Figure 1-Figure 5The sliding stopper 4 is arranged on the rotating shaft 2. The sliding stopper 4 and the rotating part 31 are provided with a sliding rod 41 and a sliding groove 312 that cooperate with each other. One end of the axis of the second gear 32 in the rotating assembly 3 passes through the through hole on the sliding stopper 4, and the other end passes through the sliding groove 312 on the rotating part 31, and is connected to the hole groove on the hinge bracket 1. The second gear 32 is rotatably supported by the sliding stopper 4 and the hinge bracket 1. The sliding rod 41 is arranged on the sliding stopper 4, parallel to the rotating shaft 2, and can be one or more. The sliding groove 312 is arranged on the rotating part 31, and the sliding groove 312 is an arc groove. The sliding rod 41 on the sliding stopper 4 slides in the sliding groove 312 to limit the rotation angle of the rotating part 31, thereby limiting the unfolding angle of the electronic device. By setting the slide groove 312 as an arc groove, the axis of the second gear 32 and the slide rod 41 can slide in the slide groove 312, thereby reducing the straight length of the slide groove 312 and reducing the width of the rotating part 31, thereby reducing the overall size of the hinge structure, so that the hinge structure can be applied to electronic products with high requirements for lightness and thinness, so that the electronic equipment has the advantages of fewer installation processes and time and smaller thickness.
[0045] Please refer to Figure 1-Figure 3 The other end of the rotating shaft 2 is sleeved with a torsion part 5, which is arranged on the side of the sliding stopper 4 away from the sliding rod 41, and includes a nut 51, a gasket 52 and a spring 53. Gaskets 52 are respectively arranged between the sliding stopper 4 and the spring 53, and between the spring 53 and the nut 51. The nut 51 is fixed to one end of the rotating shaft 2, and the spring 53 is compressed to form damping when the rotating shaft rotates. The torsion part 5 can make the rotating shaft 2 and the second body 7 connected thereto, the rotating part 31 driven by the rotating shaft 2 to rotate, and the third body 8 linked thereto stop freely when rotating.
[0046] Please refer to Figure 1-Figure 2 A mounting portion 21 is provided at one end of the rotating shaft 2. The mounting portion 21 protrudes along the radial direction of the rotating shaft 2 to form a mounting plate 211. The first body can be detachably mounted on the mounting plate 211, and the installation is simple.
[0047] Please refer to Figure 1-Figure 7 In the process of using the electronic device, when the first body 6 is rotated, the mounting portion 21 on which the first body 6 is mounted rotates accordingly, driving the first gear 22 on the rotating shaft 2 to rotate in the same direction. When the first gear 22 rotates, it drives the second gear 32 to rotate in the opposite direction. The second gear 32 drives the rotating portion 31 to rotate in the same direction as the second gear 32, that is, the rotating portion 31 rotates in the opposite direction to the first gear 22, so that when the electronic device is unfolded or folded, the first body 6 and the third body 8 rotate in the opposite direction, so that in the process of unfolding or folding the electronic device, Figure 6 In the folded state shown, the third body 8 will not be covered by the first body 6. Figure 7In the unfolded state shown, the third body 8 is at a certain angle to the second body 7, which is convenient for users to view, so that the third body 8 can be conveniently used in both the unfolded and folded states of the electronic device.
[0048] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
