Detailed Description

The embodiment of the invention provides a connecting device and electronic equipment, which are used for solving the technical problem of inconvenience in use caused by constant torsion between a first assembly and a second assembly in the prior art.

In order to solve the above technical problems, the technical solution in the embodiments of the present invention has the following general idea:

there is provided a coupling device for rotatably coupling a first component with a second component, the coupling device comprising: one end of the shaft connecting piece is used for connecting the first assembly, and the other end opposite to the one end of the shaft connecting piece is connected with a fixing piece; the sleeve connecting piece is used for connecting the second assembly, is sleeved on the shaft connecting piece and enables the second assembly to rotate around the shaft connecting piece relative to the first assembly; the tightening piece is sleeved on the shaft connecting piece and positioned between the sleeve connecting piece and the fixing piece, and the tightening piece correspondingly adjusts the extrusion force between the tightening piece and the sleeve connecting piece along with the change of the rotation angle of the first component relative to the second component.

In the technical scheme of the invention, the first assembly and the second assembly are rotatably connected through the three connecting pieces, and when the first assembly and the second assembly are at different angles, the torsion force between the first assembly and the second assembly is different.

In order to better understand the technical scheme, the technical scheme of the invention is described in detail through the drawings and specific embodiments.

In a first aspect, the present invention provides a coupling device for rotatably coupling a first component and a second component.

In an embodiment of the present invention, the first component and the second component may be two different devices, for example, the first component is a flat computer, and the second component is a supporting board or a docking station.

For example, in the prior art, the electronic device combining the tablet computer and the notebook computer can be used as the tablet computer when the tablet computer part is separated from the host computer part, and can be used as the common notebook computer when the tablet computer part is combined with the host computer part.

In addition, the first component and the second component in the embodiment of the present invention may also be the same device, for example, a conventional notebook computer is provided with a display and a host, and corresponding to the technical solution of the present invention, the first component may be the display, and the second component may be the host, and the display and the host are rotatably connected through the connecting device.

Such as a folding chair or a folding bicycle. The connecting device is arranged inside the folding chair or the folding bicycle, and two parts connected by the connecting device are equivalent to a first component and a second component in the invention. In the specific implementation process, a person skilled in the art to which the present invention pertains may set the first component and the second component according to actual situations, and the present invention is not particularly limited.

Fig. 1 is a structural diagram of a connecting device according to an embodiment of the present invention. The connecting device includes: shaft connecting piece 1, tightening piece 2 and sleeve connecting piece 3. One end of the shaft connecting piece 1 is used for connecting the first component, and the other end of the shaft connecting piece is connected with a fixing piece 4.

And the sleeve connecting piece 3 is used for connecting the second assembly, and the sleeve connecting piece 3 is sleeved on the shaft connecting piece 1 and enables the second assembly to rotate around the shaft connecting piece 1 relative to the first assembly. The axial direction of the shaft coupling 1 is, for example, the direction of a straight line (dashed line) in fig. 1 along the first shaft coupling 1, and the rotational direction is, for example, the direction of an arc (dashed line) in fig. 1.

The tightening piece 2 is sleeved on the shaft connecting piece 1 and is positioned between the sleeve connecting piece 3 and the fixing piece 4, and the tightening piece 2 correspondingly adjusts the extrusion force between the tightening piece 2 and the sleeve connecting piece 3 along with the change of the rotation angle of the first component relative to the second component.

The three connectors described above are described below: the functional principle among the shaft connecting piece 1, the tightening piece 2 and the sleeve connecting piece 3.

When the rotation angle of the first assembly relative to the second assembly along the shaft connecting piece 1 is in a first angle range, the state between the sleeve connecting piece 3 and the tightening piece 2 is a first state, and the torsion provided by the connecting device is a first torsion;

when the angle of the first component rotating along the shaft connector 1 relative to the second component is in a second angle range, the state between the sleeve connector 3 and the tightening component 2 is changed from the first state to a second state, and the torque force provided by the connecting device is a second torque force; wherein the second torsion force and the first torsion force are different.

For example, if the first component is a display body of a notebook computer and the second component is a keyboard body of the notebook computer, the display body and the keyboard body are connected through the connecting device. When the included angle between the display body and the keyboard body is in a first angle range, for example, 20 degrees to 95 degrees, the torque force provided by the connecting device is the first torque force, that is, when the user rotates the display body or the keyboard body to move the display body and the keyboard body in the range of 20 degrees to 90 degrees, the user needs to provide a force greater than or equal to the first torque force.

For another example, when the angle between the display body and the keyboard body is in a second angle range, for example, 95 to 140 degrees, the state between the sleeve-connecting member 3 and the tightening member 2 is changed from the first state to the second state, and the torque force provided by the connecting means is a second torque force different from the first torque force. That is, when the user rotates the display body or the keyboard body so that the display body and the keyboard body move within a range of 95 degrees to 140 degrees, the user needs to provide a force greater than or equal to the second torque force.

Optionally, the first state includes: the sleeve connection 3 produces a first axial displacement on the shaft connection 1, compressing the compression element 2 to a first compressed state, so that the friction between the sleeve connection 3 and the compression element 2 is a first friction, by means of which the connection device provides the first torque.

For example, when the display body rotates to 20 degrees along the axis relative to the keyboard body from 0 degree, the sleeve connector 3 axially displaces on the axis connector 1, moves outward, compresses the tightening member 2 to a first compression state, and further increases the friction force between the sleeve connector 3 and the tightening member 2 to a first friction force, so that the torque force between the display body and the keyboard body gradually increases to a first torque force, that is, a certain torque force required by a user in the process of opening the notebook computer to enable the display body to face the user.

Optionally, the second state includes: the sleeve connection 3 produces a second axial displacement on the shaft connection 1, compressing the compression element 2 to a second compressed state, so that the friction between the sleeve connection 3 and the compression element 2 is a second friction, by means of which the connection device provides the second torque.

For example, when the display body rotates to 140 degrees along the axis relative to the keyboard body, the sleeve connector 3 continues to displace in the axial direction and move outward, and continues to compress the compression member 2 to a second compression state, which is greater than the first compression state, so that the friction force between the sleeve connector 3 and the compression member 2 is increased to a second friction force, and the torque force between the display body and the keyboard body is increased from the first torque force to a second torque force. When the user is working with note notebook computer, the contained angle that shows between body and the keyboard body is usually between 95 degrees to 140 degrees, to the touchable notebook computer of display screen, can increase extra effort to showing the body when the user clicks the touch-sensitive screen, but owing to show the torsion increase to the second torsion between body and the keyboard body in 95 degrees to 140 degrees within ranges, the extra power that increases when the second torsion can be used for balancing the touchable display screen of user's touch, consequently show the body and can not appear rocking.

Alternatively, the first state and the second state may be other states as long as the other states are satisfied such that the torque provided by the connecting means is different.

The following describes possible configurations of the shaft connection 1, the sleeve connection 3 and the constriction 2.

Alternatively, the shaft connector 1 may be cylindrical, rectangular parallelepiped or handle-shaped, that is, the diameters of the two ends are larger than the diameter of the middle portion, as shown in fig. 2, which is a structural diagram of the shaft connector 1. If the different sections on the shaft connection are of different diameters, as shown in fig. 2, the smaller diameter section can be used as the shaft connection 1 of the present application, and the components required by the user can be connected for the larger diameter section. Fig. 2 is only one possible configuration for providing the shaft connecting element 1 and is not limited to the configuration of fig. 2 in the actual operation.

Alternatively, the tightening member 2 may be a compressible elastic plate or a spring, and the fixing member 4 may be a nut and fixed to the rear end of the shaft connecting member 1.

Optionally, the sleeve connection member 3 is sleeved on the shaft connection member 1 and connected to the second assembly, and the second assembly can rotate around the shaft connection member relative to the first assembly.

Alternatively, the sleeve-connecting member 3 may be connected to the second assembly by connecting the second assembly via the rotary member 5. Referring to fig. 3, fig. 3 is a schematic structural view of the rotating member 5 fixedly connected to the second assembly.

Optionally, one end of the rotating member 5 is fixedly connected to the second assembly, and the other end opposite to the one end is sleeved on the shaft connecting member 1. The other end of the rotary member 5 may be provided with a first through hole 51 having a diameter larger than that of the shaft connector 1, so that the shaft connector 1 passes through the first through hole 51, so that the rotary member 5 is fitted over the shaft connector 1, and the second assembly is rotatable about the shaft connector with respect to the first assembly.

Optionally, the sleeve connection member 3 further includes: a first set of connecting sub-elements 31, secured to the shaft connecting element 1 adjacent to the rotary element 5. A second set of connector elements 32 adjacent to the first set of connector elements 31. One end of the second set of connecting sub-members 32 is movably sleeved on the shaft connecting member 1, and the other end is connected with the rotating member 5. A third set of connecting members 33 is movably mounted on the shaft connecting member 1 adjacent to the second set of connecting members 32 and the compression member 2.

Alternatively, the other end of the second set of connecting sub-members 32 may be connected to the rotating member 5 in a manner that: the rotating part 5 fixedly connected with the second component is provided with an accommodating area, the other end of the second set of connecting sub-part 32 is placed in the accommodating area, and when the second component rotates along the shaft connecting part 1 relative to the first component under the action of external force, the other end drives the second set of connecting sub-part 32 to rotate along the shaft connecting part 1. For example, referring to fig. 3, a second through hole 52 may be provided on the rotating member 5. The other end of the second set of connector members 32 is provided with a torsion bar which passes through the second through holes 52. Of course, the receiving area may also be a slot, a slit or a blind hole, and the torsion bar may be inserted into the slot, the slit or the blind hole, as long as the other end of the second set of connecting sub-members 32 is always connected to the rotating member 5 during the relative rotation of the first component and the second component, so that the rotation of the rotating member 5 can drive the rotation of the second set of connecting sub-members 32.

The structure of the sleeve connection 3 will now be described in detail, with continued reference to fig. 1.

The relationship between the first set of connection sub-members 31, the second set of connection sub-members 32 and the third set of connection sub-members 33 in the sleeve connection 3 is: the first set of connector members 31 has first snap-fit elements on a first face adjacent the second set of connector members 32. The second set of connector pieces 32 has second snap elements on a second face adjacent to the first set of connector pieces 31 that mate with the first snap elements. The second set of connector sub-members 32 has a third engagement element on a third face adjacent to the third set of connector sub-members 33. The fourth surface of the third set of connection sub-parts 33 adjacent to the second set of connection sub-parts 32 has a fourth snap-fit element matching said third snap-fit element. During the rotation of the first assembly relative to the second assembly along the shaft connection 1, the second set of connection sub-elements 32 can be in a state of engagement or disengagement with the first set of connection sub-elements 31 and the third set of connection sub-elements 33, respectively.

One possible structure of the sleeve connection member 3 will be described below by way of example, but is not limited to this structure in practical use.

For example, referring to fig. 4, a cross-sectional view of a first face of a first set of connecting sub-members 31 is shown adjacent to a second set of connecting sub-members 32. First snap elements, which may be first recessed regions 311 and second recessed regions 312, may be provided on a first face of the first set of connection sub-members 31 adjacent to the second set of connection sub-members 32. In this embodiment, a slope 310 is disposed at one end of the first recessed area 311, and the structure of the slope 310 is shown in fig. 4, which is a schematic diagram of a possible slope. A ramp 313 is also provided at one end of the second recessed area 312. The surface of the slope may be smooth or rough, and the angle of the slope may be determined according to the actual situation, and the present invention is not particularly limited.

The size and the position of the first recessed area 311 and the second recessed area 312 may be determined according to actual situations, for example, the first recessed area 311 and the second recessed area 312 may be close to the center of a circle or far from the center of a circle. The first and second recessed

regions

311 and 312 may be curved, and the length thereof may be determined according to actual conditions.

For example, a possible structure of the second set of connecting members 32 corresponding to the first set of connecting members 31 is shown in fig. 5, which is a cross-sectional view of a second surface of the second set of connecting members 32 adjacent to the first set of connecting members 31. Adjacent to the first set of connecting sub-members 31, one end of the second set of connecting sub-members 32 is movably sleeved on the shaft connecting member 1 along the axial direction, and the other end is a torsion bar 321, and the structure of the torsion bar 321 is shown in fig. 5, which is a cross-sectional view of a possible torsion bar. The torsion bar 321 is inserted into the receiving area of the rotary member 5 so that the second set of connection sub-members 32 is connected with the second device.

The second set of connector parts 32 has second snap elements on a second face adjacent to the first set of connector parts 31 that mate with the first snap elements. Thus, a first raised area 3201 mating with the first recessed area 311 on the first side of the first set of connecting sub-members 31 and a second raised area 3202 mating with the second recessed area 312 may be provided on a second side of the second set of connecting sub-members 32 adjacent to the first set of connecting sub-members 31.

Optionally, the size of the first protruding area 3201 is smaller than that of the first recessed area 311, and the size of the second protruding area 3202 is smaller than that of the second recessed area 312, so as to ensure that the first protruding area 3201 can be engaged in the first recessed area 311 and can move in the first recessed area 311, and the second protruding area 3202 can be engaged in the second recessed area 312 and can move in the second recessed area 312.

Similarly, one end of the first protrusion area 3201 is also provided with the slope 320. One end of the second protruding area 3202 is provided with a slope 322, and the structures of the slope 320 and the slope 322 are shown in fig. 5, which is a schematic structural diagram of a possible slope. The slope 320 mentioned here is the same as the slope angle of the slope 310 of the first and second recessed

regions

311 and 312 described above. Meanwhile, the slope 322 has the same inclination angle as the slope 313 of the second recess region 312 described above. So that the first and second

protruding regions

3201 and 3202 can be completely engaged in the first and second recessed

regions

311 and 312.

Third snap elements, which may be third and fourth recessed

regions

3211 and 3212, are provided on a third side of the second set of connection sub-pieces 32 adjacent to the third set of connection sub-pieces 33. Referring to fig. 6, a cross-sectional view of a third side of the second set of connecting sub-members 32 adjacent to the third set of connecting sub-members 33 is shown. Similarly, the size and the position of the third recessed area 3211 and the fourth recessed area 3212 may be determined according to actual conditions, for example, the third recessed area 3211 and the fourth recessed area 3212 may be close to the center of a circle or far from the center of a circle. One end of the third recessed region 3211 is provided with a slope 323, and the structure of the slope 323 is shown in fig. 6, which is a schematic diagram of a possible slope. Also, slopes 324 are respectively provided at both ends of the fourth concave region 3212.

For example, referring to fig. 7, a structure of the third set of connecting sub-members 33 corresponding to the second set of connecting sub-members 32 is shown as a cross-sectional view of a fourth surface of the third set of connecting sub-members 33 adjacent to the second set of connecting sub-members 32. The fourth surface of the third set of connecting sub-members 33 adjacent to the second set of connecting sub-members 32 has a fourth engaging element matching the third engaging element. Corresponding to the second set of connecting sub-members 32 described above, the fourth snap elements may be third and fourth raised

areas

331, 332 corresponding to the third and fourth recessed

areas

3211, 3212 on the second set of connecting sub-members 32. The third set of connecting sub-members 33 is movably sleeved on the shaft connecting member 1 along the axial direction, and is adjacent to the tightening member 2.

Optionally, the size of the third protruding area 331 is slightly smaller than that of the third recessed area 3211, and the size of the fourth protruding area 332 is slightly smaller than that of the fourth recessed area 3212, so as to ensure that the third protruding area 331 can be engaged with the third recessed area 3211, and the fourth protruding area 332 can be engaged with the fourth recessed area 3212.

Similarly, a slope 330 is provided in the third projection region 331, and a slope 333 is also provided in the fourth projection region 332. The structures of the ramp 330 and the ramp 333 are shown in fig. 7, which is a schematic structural diagram of a possible ramp. The slope 330 mentioned here has the same inclination angle as the slope 323 of the third recessed region 3211 described above. Meanwhile, the slope 333 has the same inclination angle as the slope 324 of the fourth recessed region 3212 described above. It should be noted that the size of the top surface of the third protruding area 331 is equal to the size of the bottom surface of the third recessed area 3211. The dimensions of the top surface of the fourth protruding region 332 are equal to the dimensions of the bottom surface of the fourth recessed region 3212. That is, the third protruded area 331 may fill the third recessed area 3211, and the fourth protruded area 332 may fill the fourth recessed area 3212.

The movement of the sleeve connection 3 during a change of the angle between the first and second components is described below.

During the process of increasing the included angle from the first angle to the second angle, the first set of connecting members 31 and the second set of connecting members 32 are in the engaged state, the third set of connecting members 33 moves along the axial direction towards the tightening member 2, so that the second set of connecting members 32 are gradually in the disengaged state from the engaged state, the third set of connecting members 33 compress the tightening member 2 to the first compressed state, and the torsion between the first component and the second component is the first torsion.

In the process that the included angle is increased from the third angle to the fourth angle, the second set of connecting sub-member 32 moves towards the third set of connecting sub-member 33 along the axial direction, so that the first set of connecting sub-member 31 is gradually in the separated state from the clamped state, the third set of connecting sub-member 33 is in the separated state, the tightening member 2 is compressed to the second compressed state, the torsion between the first component and the second component is the second torsion, and the second torsion is larger than the first torsion.

The above process is illustrated below by way of example.

When the first assembly and the second assembly are overlapped, that is, the included angle between them is 0 degree, the first set of connecting sub-member 31, the second set of connecting sub-member 32 and the third set of connecting sub-member 33 are in the engagement state, that is, the first protruding area 3201 on the second set of connecting sub-member 32 is caught on the first recessed area 311 on the first set of connecting sub-member 31, and the second protruding area 3202 is caught on the second recessed area 312 on the first set of connecting sub-member 31. Meanwhile, the third protruding areas 331 on the third set of connection sub-member 33 are caught in the third recessed areas 3211 on the second set of connection sub-member 32, and the fourth protruding areas 332 are caught in the fourth recessed areas 3212 on the second set of connection sub-member 32.

At 0 to 20 degrees, i.e. during a 20 degree rotation of the first assembly with respect to the second assembly, the third set of connection sub-elements 33 and the second set of connection sub-elements 32 start to climb, i.e. the third protruding areas 331 on the third set of connection sub-elements 33 start to move up the ramps 323 of the third recessed areas 3211 on the second set of connection sub-elements 32. At the same time, the fourth protruding region 332 begins to move up the ramp 324 of the fourth recessed region 3212 on the second set of connecting sub-members 32. Fig. 8 shows the process of the convex region climbing along the concave region. In the process, the third set of connecting elements 33 moves outwards and compresses the compression element 2 continuously, bringing it to a compressed state. Since the compression of the constriction 2 increases, which leads to an increase in friction, the torque between the first and the second component increases during the course of 0 to 20 degrees until the first torque is reached.

At 20 degrees, the third set of connecting sub-members 33 and the second set of connecting sub-members 32 complete the climbing, i.e., the third protruding areas 331 on the third set of connecting sub-members 33 move completely out of the third recessed areas 3211 along the slope of the third recessed areas 3211 on the second set of connecting sub-members 32. At the same time, the fourth protruding region 332 on the third set of connecting sub-member 33 moves completely out of the fourth recessed region 3212 along the slope on the fourth recessed region 3212 on the second set of connecting sub-member 32. The third set of connection members 33 and the second set of connection members 32 are now in a disengaged state, while the first set of connection members 31 and the second set of connection members 32 are in an engaged state. While the constriction 2 is compressed to the first compression state.

It should be noted that during the process of 0 degrees to 20 degrees, the first protruding area 3201 on the second set of connecting sub-members 32 moves in the first recessed area 311 of the first set of connecting sub-members 31, and has not yet moved to the slope 310 of the first recessed area 311. While the second protruding area 3202 on the second set of connecting sub-members 32 moves within the second recessed area 312 of the first set of connecting sub-members 31 and does not move to the slope 313 of the second recessed area 312.

In the course of 20 to 95 degrees, the third set of connecting sub-members 33 and the second set of connecting sub-members 32 have completed climbing, i.e., the third convex regions 331 and the fourth convex regions 332 on the third set of connecting sub-members 33 are tangent to and move along the other non-recessed flat portions of the second set of connecting sub-members 32 except for the third recessed regions 3211 and the fourth recessed regions 3212. In the process, the third set of connecting elements 33 is not moved outwards, so that the compression of the compression element 2 is not changed, i.e. the torque is not changed, so that the torque of the first and second elements is still the first torque.

As will be explained herein, during the 20 to 95 degree process, the first protruding areas 3201 on the second set of connecting sub-members 32 still move within the first recessed areas 311 of the first set of connecting sub-members 31, while the second protruding areas 3202 on the second set of connecting sub-members 32 also still move within the second recessed areas 312 of the first set of connecting sub-members 31. The reason for this is that the central angle subtended by the radians of the first recessed area 311 and the second recessed area 312 is equal to 95 degrees. Of course, in practical applications, the radian of the first concave region 311 and the second concave region 312 may be determined according to specific situations, and is not necessarily 95 degrees.

During the course of 95 degrees to 140 degrees, the first set of connecting sub-members 31 and the second set of connecting sub-members 32 begin to climb, i.e., the first protruding regions 3201 of the second set of connecting sub-members 32 move to the slopes 310 of the first recessed regions 311 and begin to move up the slopes 310 of the first recessed regions 311 of the first set of connecting sub-members 31. At the same time, the second protruding regions 3202 of the second set of connecting sub-members 32 move to the ramps 313 of the second recessed regions 312 and begin to move up the ramps 313 of the second recessed regions 312 of the first set of connecting sub-members 31. During the movement, the second set of connecting members 32 starts to move outwards and gradually compresses the compression member 2, making it more compressed, while the friction gradually increases, so that the generated torsion force continuously increases and when 145 degrees is reached, the first protruding area 3201 moves completely out of the first recessed area 311, and the second protruding area 3202 moves completely out of the second recessed area 312, while the third set of connecting members 33 and the second set of connecting members 32 are in a separated state, while the first set of connecting members 31 and the second set of connecting members 32 are also in a separated state. While the constriction 2 is in a second compressed state. The second compression state is greater than the first compression state. The torque between the first and second assemblies is increased to a second torque, which is greater than the first torque.

In the course of 140 degrees to 160 degrees, the first set of connecting sub-members 31 and the second set of connecting sub-members 32 have completed climbing, i.e., the first protruding areas 3201 and the second protruding areas 3202 on the second set of connecting sub-members 32 begin to move tangentially along other non-recessed flat portions of the first set of connecting sub-members 31 except for the first recessed areas 311 and the fourth recessed areas 3212. In the process, the second set of connecting elements 32 is not moved outwards, so that the compression of the compression element 2 is not changed, i.e. the torque is not changed.

In the course of 160 to 180 degrees, the first set of connecting sub-members 31 and the second set of connecting sub-members 32 start to descend a slope, the so-called downhill process: that is, the first protruding region 3201 of the second set of connecting sub-members 32 has rotated to the second recessed region 312 of the first set of connecting sub-members 31 and begins to move down the other ramp 314 of the second recessed region 312 of the first set of connecting sub-members 31 relative to the ramp 313, eventually moving down inside the second recessed region 312. At the same time, the second protruding region 3202 of the second set of connecting sub-members 32 has rotated into the first recessed region 311 of the first set of connecting sub-members 31 and begins to move down the other ramp 315 of the first recessed region 311 of the first set of connecting sub-members 31 relative to the ramp 310 into the interior of the first recessed region 311. At this point the second set of connecting members 32 begins to move closer to the first set of connecting members 31 and the compression member 2 begins to recover, at which point the amount of compression is gradually reduced and the resulting torque force is reduced.

The case after 180 degrees is similar to the case from 0 degrees described above, and is not described here for the sake of brevity of the description.
