Fig. 1A to 1B schematically show application scenarios of a connection device according to an embodiment of the present disclosure. Fig. 1A schematically illustrates a schematic diagram of an electronic device in a closed state according to an embodiment of the present disclosure. Fig. 1B schematically shows a schematic view of an electronic device in an open state according to an embodiment of the disclosure.

As shown in fig. 1A and 1B, the connection device 300 may be used in an electronic device 10, such as a notebook computer, a tablet computer with an external device, and the like.

The electronic device 10 comprises a first part 100, a second part 200 and a connecting means 300. The connection device 300 is capable of connecting the first part 100 and the second part 200 of the electronic device 10 and enabling the first part 100 to rotate relative to the second part 200.

For example, when the electronic device 10 is a notebook computer, the first portion 100 may be a system side of the notebook computer, and the second portion 200 may be a display side of the notebook computer. Specifically, the first portion 100 may be provided with a keyboard, a fingerprint acquisition device, a touch pad, and the like, and how to set the first portion specifically is not limited in the embodiment of the present application. The second portion 200 may be provided with a display screen, where the display screen may be a display screen with a touch function, or may also be a display screen without touch, and herein, the embodiment of the present application is not limited.

When the electronic device 10 is a notebook computer, the connecting device 300 connects the first portion 100 and the second portion 200, and enables the first portion 100 to rotate relative to the second portion 200, so that the opening and closing of the electronic device, such as the notebook computer, can be realized.

Specifically, as shown in fig. 1A, the connection device 300 is disposed on the outer side of the electronic device 10 when the first part 100 and the second part 200 of the electronic device 10 are in the closed state, that is, the connection device 300 is disposed on one side of the first part 100 and the second part 200 when the electronic device 10 is in the closed state. For example, in the embodiment of the disclosure, when the electronic device 10 is in the closed state and the connection device 300 is disposed outside the electronic device 10, the portions of the first part 100 and the second part 200 near the connection portion can contact each other, so that the influence of the connection device 300 on the size of the electronic device can be reduced, and the electronic device can be designed to be more light and thin. As shown in fig. 1B, when the first portion 100 and the second portion 200 of the electronic device 10 are in an open state, for example, open 180 degrees, the connection device 300 may be disposed between the first portion 100 and the second portion 200 such that the first portion 100 and the second portion 200 have a first distance therebetween.

The structure of the connection device according to the exemplary embodiment of the present disclosure is described below with reference to fig. 2 to 5C in conjunction with the application scenarios of fig. 1A to 1B. It should be noted that the above application scenarios are merely illustrated for the convenience of understanding the spirit and principles of the present invention, and the embodiments of the present invention are not limited in this respect. Rather, embodiments of the present invention may be applied to any scenario where applicable.

Fig. 2 schematically shows a structural schematic view of an electronic device and a connecting arrangement according to an embodiment of the disclosure; FIG. 3 schematically illustrates a structural schematic of a connection device according to an embodiment of the disclosure; and fig. 4 schematically illustrates an exploded view of a connection device according to an embodiment of the disclosure.

As shown in fig. 2, 3 and 4, the connecting device 300 includes a rotating shaft 310, a first bracket 321, a second bracket 331, a first connecting member 340, a second connecting member 350 and an elastic device 360.

Specifically, the rotation shaft 310 is connected to one of the first and

second parts

100 and 200. In the disclosed embodiment, the shaft 310 may be coupled to the first portion 100.

According to the embodiment of the present disclosure, the rotation shaft 310 may have a cylindrical structure that is symmetrical along the axial direction, for example, a portion of the rotation shaft 310 may have a cylindrical shape so that the partial structure can rotate with respect to the rotation shaft, or a portion of the rotation shaft 310 may have a prismatic shape so that the partial structure is fixed so that the partial structure cannot rotate with respect to the rotation shaft 310. It is to be understood that the present disclosure is not limited to the shape of the shaft 310, as long as it is ensured that each fitting connected to the shaft 310 can perform its function.

The first bracket 321 is sleeved on the rotating shaft 310 and connected with the other of the first part 100 and the second part 200. Wherein the first support 321 can rotate relative to the rotating shaft 310.

According to an embodiment of the present disclosure, the connection device 300 includes at least one first bracket. For example, as shown in fig. 4, a first bracket 321 and a first bracket 322 may be included. It is to be understood that fig. 4 is merely an exemplary illustration and the present disclosure does not limit the number of first brackets. In the disclosed embodiments, the plurality of first brackets may have the same or similar structure.

In the embodiment of the present disclosure, the

first brackets

321 and 322 may be connected with the second portion 200, for example, may be fixed on the second portion 200 (for example, may be implemented by a process such as integral molding). Specifically, the

first brackets

321 and 322 may be disposed outside the second portion 200, so that the hinge 310 may be disposed outside the electronic device 10 when the first portion 100 and the second portion 200 are in the closed state. When the electronic device is a notebook computer, the outer side of the second portion 200 may be, for example, a side of the display end, such as a side between the a-cover and the B-cover. It is understood that the disclosed embodiments do not limit the connection manner of the first bracket 100 and the second portion 200, as long as the

first brackets

321 and 322 can be fixed to the second portion 200.

Specifically, as shown in fig. 4, the first bracket 322 has a first portion and a second portion, wherein an included angle of less than 180 degrees is formed between the first portion and the second portion, for example, the first bracket may have an L-shaped structure, wherein one end of the L-shape is fixed to the second portion 200, and the other end is sleeved on the rotating shaft 310.

In the embodiment of the present disclosure, the first bracket 322 further includes a first hole 3221 and a second hole 3222, wherein the first hole 3221 is a circular hole, and the first bracket 322 may be sleeved on the rotating shaft 310 through the first hole 3221. Accordingly, the rotation shaft 310 is cylindrical at a position contacting the first bracket so that the first bracket can rotate with respect to the rotation shaft 310. It is understood that the first bracket 321 may have the same or similar structure as the first bracket 322. The second hole 3222 of the first support may be a through hole with a polygonal cross section, for example, and the first support 321 is connected to the first connecting member 340 through the second hole.

The second bracket 331 is coupled to one of the first and

second parts

100 and 200 to fix the rotation shaft 310.

According to an embodiment of the present disclosure, the connection device 300 includes at least one second bracket. For example, as shown in fig. 4, a second bracket 331 and a second bracket 332 may be included. It is to be understood that fig. 4 is merely an exemplary illustration and the present disclosure does not limit the number of second brackets. In the disclosed embodiment, the plurality of second brackets may have the same or similar structure.

In the embodiment of the present disclosure, the

second brackets

331 and 332 may be connected to the first portion 100, for example, may be fixed on the first portion 100 (for example, may be implemented by a process such as integral molding). Specifically, the

second brackets

331 and 332 may be disposed outside the first portion, so that the hinge 310 may be disposed outside the electronic device 10 when the first portion 100 and the second portion 200 are in the closed state. When the electronic device is a notebook computer, the outer side of the first portion may be, for example, a side of the system side, such as a side between the C-cover and the D-cover. It can be understood that the embodiment of the present disclosure does not limit the connection manner of the second bracket and the first portion as long as the second bracket can be fixed to the first portion.

Specifically, as shown in fig. 4, one end of the second bracket 331 is fixed to the first portion 100, and the other end is sleeved on the rotating shaft 310.

In the embodiment of the present disclosure, the second bracket 331 may fix the rotation shaft 310 by being engaged with the rotation shaft 310. For example, the second holder 331 further includes a third hole 3311, wherein the third hole 3311 may be a prism-shaped hole (e.g., a hole having a rectangular cross-section), and the second holder 331 may be sleeved on the rotation shaft 310 through the third hole 3311. Accordingly, the rotation shaft 310 has a corresponding prism shape (e.g., a cylindrical structure having a rectangular cross-section) at a position contacting the second holder 331, so that the second holder 331 can fix the rotation shaft 310 such that the rotation shaft 310 cannot rotate with respect to the first part 100. The present disclosure does not limit the connection manner of the rotating shaft 310 and the second bracket 331 (for example, the rotating shaft 310 and the second bracket 331 can also be connected by fixing or gluing), and the structural shape of the second bracket 331, as long as the rotating shaft 310 and the first portion 100 can not rotate relatively.

It is understood that the second holder 332 may have the same or similar structure as the second holder 331.

The first connecting member 340 is sleeved on the rotating shaft 310. According to the embodiment of the present disclosure, the first connecting member 340 is sleeved on the rotating shaft 310 and can rotate relative to the rotating shaft 310. The first connector 340 is connected to the first bracket 321, such that the connector 340 is fixed by the first bracket 321, such that the connector 340 cannot rotate with respect to the first bracket 321, nor with respect to the second portion 200.

Specifically, as shown in fig. 4, the first connector 340 includes at least one first groove 341 and a connection protrusion 342. The first connector 340 may have a circular through hole, for example, and is sleeved on the rotating shaft 310 through the circular through hole. Accordingly, the rotation shaft 310 may be a corresponding cylinder type at a portion position contacting the first connector 340, so that the first connector 340 may rotate with respect to the rotation shaft 310.

The first connecting member 340 may be connected to the first bracket 321 through a connecting protrusion 342, for example, the connecting protrusion 342 may be engaged with the second hole of the first bracket 321 to connect to the first bracket. In the disclosed embodiment, the connection protrusion 342 may be a protrusion having a polygonal (e.g., rectangular) cross-section, and accordingly, the second hole of the first bracket 321 is a corresponding polygonal (e.g., rectangular) through-hole, so that the first connector 340 can be connected to the first bracket 321 and cannot rotate with respect to the first bracket 321.

The second connector 350 is sleeved on the rotating shaft 310 and can move axially relative to the rotating shaft 310. According to the embodiment of the present disclosure, the second connector 350 is provided with a first protrusion 351 corresponding to the first groove 341. The second connector 350 may be in contact with the first connector 340, for example. In the embodiment of the present disclosure, the second connector 350 may be disposed on the rotating shaft 310 through a non-circular through hole, for example, so that the second connector 350 can move axially relative to the rotating shaft 310, but cannot rotate relative to the rotating shaft 310.

The elastic device 360 is sleeved in the rotating shaft 310 and contacts with the second connecting member 350. The elastic means may be, for example, a spring or a leaf spring. In the disclosed embodiment, the elastic device 360 may move axially along the rotating shaft 310, for example, may be stretched or compressed along the axial direction of the rotating shaft 310.

For example, as shown in fig. 4, one end of the elastic device 360 is in contact with the second bracket 332 through a gasket 372, and in the embodiment of the present disclosure, the second bracket 332 is fixed to the first portion 100, so that the end of the elastic device 360 in contact with the second bracket 332 cannot move axially. The other end of the elastic device 360 is in contact with the second connecting member 350, and the second connecting member 350 can move axially, so that the elastic device 360 can be elastically deformed.

According to the embodiment of the present disclosure, the

first brackets

321 and 322 are fixed to the second portion 200, and the rotation shaft 310 is connected to the first portion 100 through the

second brackets

331 and 332. Therefore, during the opening or closing process of the electronic device, the first bracket rotates relative to the rotating shaft, and the first connecting member 340 is connected to the first bracket, so that the first bracket drives the first connecting member 340 to rotate relative to the rotating shaft. When the first connector 340 rotates relative to the rotating shaft, the second connector 350 cannot rotate but only moves axially, so that the second connector 350 can move axially relative to the rotating shaft 310 under the cooperation of the first groove 341 and the first protrusion 351, and the elastic device 360 is elastically deformed.

Specifically, reference is made to fig. 5A-5C for a schematic illustration of the relative positions of the first connector 340 and the second connector 350 according to an embodiment of the disclosure. Fig. 5A to 5C are views of fig. 1A taken along direction a.

As shown in fig. 5A, when the first part 100 and the second part 200 are in the closed state, the first protrusion 351 of the second connector 350 may be in full contact with the first groove 341 of the first connector 340, and the elastic device 360 may be in a relaxed state.

During the opening of the first and

second portions

100 and 200, for example, from 0 degrees to 60 degrees, the relative positions of the first and

second connection members

340 and 350 may be changed, for example, from the position shown in fig. 5A to the position shown in fig. 5B, and then from the position shown in fig. 5B to the position shown in fig. 5C.

As shown in fig. 5A to 5C, when the first connector 340 and the second connector 350 rotate relatively, the first protrusion 351 of the second connector 350 rotates from a state of being completely contacted with the first groove 341 of the first connector 340 to a state of being partially contacted with the first groove 341, and finally the first protrusion 351 rotates out of the first groove 341 to be contacted with the edge of the first connector 340. In the above process, the second connector 350 is moved away from the first connector 340 along the axial direction of the rotation shaft, so as to press the elastic means 360, and to press the elastic means 360, thereby providing torsion force for the opening process of the first and

second parts

100 and 200 with respect to each other. It will be appreciated that the magnitude of the torsional force is related to the relative position between the first connector 340 and the second connector 350. For example, when the relative position between the first connector 340 and the second connector 350 is as shown in fig. 5A, the torsion is the smallest, and the elastic device 360 is more and more stressed and thus provides more and more torsion during the process of changing the relative position between the first connector 340 and the second connector 350 from the position shown in fig. 5A to the position shown in fig. 5C.

For example, when the electronic device 10 is opened to 60 degrees, the first protrusion 351 is rotated to a position contacting with the edge of the first connector 340, and when the electronic device 10 is opened from 60 degrees to, for example, 120 degrees, the first protrusion 351 is contacted with the edge of the first connector 340 and relatively rotated along the edge, the second connector 350 no longer axially moves relative to the first connector 340, so that the elastic deformation of the elastic device 360 is unchanged, and the torque provided is unchanged.

It is understood that the above angles are only for the understanding, and specifically, in which angle ranges the torsion needs to be provided, and in which angle ranges the torsion is kept constant, and those skilled in the art can design the shape of the groove, the size of the edge, and the like according to actual situations.

Similarly, during the closing process of the first and

second portions

100 and 200, for example, from 150 degrees to 60 degrees, the first protrusion 351 rotates along the edge of the first connection element 340, and the second connection element 350 does not move axially relative to the first connection element 340, so that the elastic deformation of the elastic device 360 is unchanged, and the torque provided is unchanged.

During the process of closing the electronic device 10 from 60 degrees to 0 degrees, the relative positions of the first piece of connection 340 and the second piece of connection 350 may change from the position shown in fig. 5C to the position shown in fig. 5B, and then from the position shown in fig. 5B to the position shown in fig. 5A, for example.

As shown in fig. 5A to 5C, when the first connecting element 340 and the second connecting element 350 rotate relatively, the first protrusion 351 of the second connecting element 350 enters the first groove from the edge of the first connecting element, and due to the thrust of the elastic device 360 and the cooperation between the first groove 341 and the first protrusion 351, the second connecting element 350 can move close to the first connecting element 340, so as to reduce the pressure on the elastic device 360, and provide a relatively reduced torque.

It is to be understood that the above examples regarding the positions and movement processes of the first and

second connectors

340 and 350 are only for the sake of understanding.

First, the shape of the first groove is not limited in the present disclosure, the first groove may be a trapezoid, or may also be an arc, and a person skilled in the art may design the shape of the first groove according to actual needs. Similarly, the shape of the first protrusion is not limited in the present disclosure, as long as the first protrusion can move in cooperation with the first groove.

Furthermore, the number of the first grooves is not limited in the present disclosure, the above example only shows the case of having one first groove, and the present disclosure can design a plurality of grooves according to the actual needs. For example, two symmetrical recesses may be provided, which provides more variable torque during opening and closing of the electronic device.

Moreover, the slope of the first groove and the size of the opening are not limited in the present disclosure, the above examples are only exemplary embodiments, and those skilled in the art can design the slope of the first groove and the size of the opening according to the matching relationship between the angle and the torsion force required in actual situations, for example, the size of the opening of the groove and the size of the parallel edge may be 1: 2, or 1: 3, etc.

According to an embodiment of the present disclosure, the connection device 300 may further include a nut 380 for fixing the rotation shaft 310. For example, as shown in fig. 4, the rotation shaft 310 may be fixed to the outside of the first part 100 by the

second brackets

331 and 332 and the nut 380.

In the embodiment of the disclosure, gaskets are arranged among the components to avoid the problems of loss and the like caused by friction. For example, as shown in fig. 4, a gasket 3711 may be included between the second bracket 331 and the first bracket 321, a gasket 3712 may be included between the second bracket 332 and the first bracket 322, a gasket 372 may be included between the elastic device 360 and the second bracket 332, and a gasket 373 may be included between the first bracket 322 and the nut 380.

The connecting device 300 according to the embodiment of the present disclosure fixes the rotating shaft to the outside of the electronic device 10 through the at least one first bracket and the at least one second bracket, so as to reduce the influence of the rotating shaft on the size of the electronic device, and enable the electronic device to be designed to be thinner and lighter. And, the pivot structure is arranged in the outside of electronic equipment makes this electronic equipment have more novel outward appearance to provide good visual experience for the user.

The connecting device 300 provided by the embodiment of the present disclosure can provide gradually changed torque force through the cooperation of the first connection 340, the second connection 350 and the elastic device 360, for example, when the electronic device is opened, the torque force can be changed from small to large, and when the electronic device is closed, the torque force can be changed from large to small, so that the electronic device can be conveniently used by a user, and the user experience is improved.

The present disclosure also provides an electronic device 10 comprising a first portion 100, a second portion 200, and at least one of the above-described connecting means 300.

The first part 100 and the second part 200 may be connected by a connecting means 300, for example, by one connecting means 300, which may be placed at a middle position on one side of the electronic device, or may be connected by two connecting means 300, for example, two connecting means may be placed at symmetrical positions on one side of the electronic device. It is understood that the present disclosure does not limit the number of the connection devices 300, and those skilled in the art can arrange them according to actual situations.

In the embodiment of the present disclosure, the electronic device may be a notebook computer, or a tablet computer with an external device.

The connecting device 300 may include a rotating shaft, a first bracket, a second bracket, a first connecting member, a second connecting member, and an elastic device. Specifically, the connecting device described above with reference to fig. 2 to 5C may be used, and will not be described herein again.
