Detailed Description
The invention discloses a rotary connecting structure, which aims to reduce the limitation of designing the rotary connecting structure. The invention also provides electronic equipment and a rotation method of the electronic equipment.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 13, an embodiment of the present invention provides a rotary connection structure, which includes a first connection portion 1, a second connection portion 9, a connecting rod assembly, and a damping member 8. The connecting rod assembly drives the first connecting part 1 and the second connecting part 9 to switch between a first relative position and a second relative position; the first connecting part 1 and the second connecting part 9 are in a first relative position, and the first connecting part 1 and the second connecting part 9 are folded oppositely; the first connecting part 1 and the second connecting part 9 are in a second relative position, and the first connecting part 1 and the second connecting part 9 are relatively unfolded; the damping part 8 is axially arranged on the second connecting part 9 and is used for connecting the connecting rod assembly and the second connecting part 9; based on the axial movement of the damping part, the damping force is provided for the first connecting part 1 and the second connecting part 9 at the first relative position, the second relative position and any position switched between the first relative position and the second relative position.
According to the rotary connection structure provided by the embodiment of the invention, the first connection part 1 and the second connection part 9 are switched between the first relative position and the second relative position through the connecting rod assembly, and the damping part 8 is connected with the connecting rod assembly and the second connection part 9, wherein the damping part 8 is axially arranged on the second connection part 9, and based on the axial movement of the damping part 8, damping force is provided for the first connection part 1 and the second connection part 9 in the processes of the first relative position, the second relative position and any position switched between the first relative position and the second relative position. Because damping part 8 is axially installed in second connecting portion 9, the relative position relation between link assembly and second connecting portion 9 is changed through the relative position switching of first connecting portion 1 and second connecting portion 9, realize that link assembly drives damping part 8 axial motion, and, realize providing of damping part 8's damping force based on damping part 8 axial motion, avoided setting up the part that provides damping force such as friction disc at link assembly's articulated position, reduced the structural constraint to link assembly's articulated shaft (such as the diameter size of articulated shaft and the intensity of articulated shaft etc.), also need not to consider to reserve the installation space that provides the part such as damping holding power such as friction disc on the articulated shaft etc. effectively reduced the structural constraint to link assembly, and then reduced the restriction of design rotation connection structure.
It will be appreciated that the damping member 8 is mounted axially to the second connection portion 9, i.e. the axial direction of the damping member 8 is parallel to the plane in which the damping member 8 is mounted to the second connection portion 9.
It should be noted that there are various ways of providing the damping force based on the axial movement of the damping member 8. If the body 81 of the damping member 8 is fixed relative to the second connecting portion 9, the damping connecting end 82 of the damping member 8 extends or contracts relative to the body 81, and the driving force required for the extension or contraction of the damping connecting end 82 relative to the body 81 provides the damping force for the damping member 8. Alternatively, the body 81 of the damping member 8 moves relative to the second connecting portion 9, and the frictional force between the body 81 of the damping member 8 and the second connecting portion 9 is the damping force provided by the damping member 8.
The connecting rod assembly comprises a rotating connecting rod set and a damping connecting rod set.
It is understood that the rotation link group provides the first connection portion 1 and the second connection portion 9 with a rotation supporting force so as to enable the first connection portion 1 and the second connection portion 9 to achieve and switch between the first relative position and the second relative position. Since the first connecting portion 1 and the second connecting portion 9 have relative thicknesses, when the first connecting portion 1 and the second connecting portion 9 are folded relatively, a certain distance between the first connecting portion 1 and the second connecting portion 9 may be inevitably required, and the movement of the damping linkage may not be affected. Therefore, in the rotary connection structure provided by the embodiment of the present invention, the rotary linkage includes at least two mutually hinged rotary connecting rods, one end of the rotary linkage is hinged to the first connecting portion 1, and the other end of the rotary linkage is hinged to the second connecting portion 9. Wherein, the two mutually hinged rotating connecting rods rotate relatively; one end of the rotating connecting rod group is hinged with the first connecting part 1, namely, the end part of the rotating connecting rod positioned at one side of the rotating connecting rod group in at least two mutually hinged rotating connecting rods is hinged with the first connecting part 1; the other end of the rotation linkage is hinged to the second connection part 9, i.e. the end of the rotation connecting rod on the other side of the rotation linkage of the at least two mutually hinged rotation connecting rods is hinged to the second connection part 9. Make first connecting portion 1, at least two mutual articulated rotation connecting rod and second connecting portion 9 connect gradually, and the connected mode is articulated, make first connecting portion 1, the connection structure that rotation linkage and second connecting portion 9 formed have three articulated department at least, so that when adjusting first connecting portion 1 and second connecting portion 9 and being in first relative position according to the demand, first connecting portion 1 and the relative folding interval of second connecting portion 9 and the relative folding gross thickness of first connecting portion 1 and second connecting portion 9.
Wherein the angle between the two mutually hinged swivel connection levers is related to the angle formed between the first connection portion 1 and the second connection portion 9. That is, as the first connecting portion 1 and the second connecting portion 9 are switched between the first relative position and the second relative position, the included angle between the two mutually hinged pivotal connecting rods is also changed.
And, the damping link group provides damping force to the first connecting portion 1 and the second connecting portion 9, so that the first connecting portion 1 and the second connecting portion 9 can realize a positioning effect at the first relative position, the second relative position and any position switched between the first relative position and the second relative position. Because the damping linkage includes two at least articulated damping connecting rods each other, the one end of damping linkage is articulated with first connecting portion 1, the other end of damping linkage can slide and be connected with damping part 8 for second connecting portion 9, consequently, with the in-process that first connecting portion 1 and second connecting portion 9 switch between first relative position and second relative position, first connecting portion 1 moves for second connecting portion 9, the motion of first connecting portion 1 is converted into through the damping linkage and is slided for second connecting portion 9, damping part 8 has been realized for the slip of second connecting portion 9, and then damping part 8 has been realized providing damping force. Wherein, the two damping connecting rods hinged with each other rotate relatively; one end of the damping connecting rod group is hinged with the first connecting part 1, namely, the end part of the damping connecting rod positioned at one side of the damping connecting rod group in at least two mutually hinged damping connecting rods is hinged with the first connecting part 1; the other end of the damping linkage is slidable relative to the second connection portion 9 and connected to the damping member 8, i.e. the end of the damping connecting rod on the other side of the damping linkage of the at least two mutually hinged damping connecting rods is slidable relative to the second connection portion 9 and is connected to the damping member 8. The first connecting portion 1, the at least two mutually hinged damping connecting rods and the second connecting portion 9 are sequentially connected, and the connection mode of two adjacent components in the first connecting portion 1 and the at least two mutually hinged damping connecting rods is hinged, so that the connection structure of the first connecting portion 1 and the damping connecting rod group at least has two hinged parts, and the damping connecting rod group and the second connecting portion 9 have one hinged part and one sliding connection part, so that when the first connecting portion 1 and the second connecting portion 9 are switched between the first relative position and the second relative position according to requirements, the first connecting portion 1 moves relative to the second connecting portion 9, the movement of the first connecting portion 1 is converted into sliding relative to the second connecting portion 9 through the damping connecting rod group, the sliding of the damping part 8 relative to the second connecting portion 9 is realized, and the damping part 8 provides damping force, and the connection structure of the first connecting portion 1 and the damping connecting rod group at least has two hinged parts, so that the rotation connecting rod group cannot be limited to provide rotation support for the first connecting portion 1 and the second connecting portion 9.
Likewise, the angle between two mutually hinged damping connecting rods is related to the angle formed between the first connecting portion 1 and the second connecting portion 9. That is, as the first connecting portion 1 and the second connecting portion 9 are switched between the first relative position and the second relative position, the included angle between the two damping connecting rods hinged to each other is also changed.
Preferably, in this embodiment, the damping member 8 is an axial displacement damper.
Of course, it is also possible to provide only a damping linkage, with the first connection 1 and the second connection 9 being directly articulated. Alternatively, the rotation linkage has only one connecting rod that hingedly connects the first connecting portion 1 and the second connecting portion 9.
In this embodiment, the damping linkage includes a first middle link 4, a second outer link 5 and a displacement link. One end of the first middle connecting rod 4 is hinged with the first connecting part 1; the other end of the first middle connecting rod 4 is hinged with the first position of the second outer connecting rod 5, and the second position of the second outer connecting rod 5 is hinged with the second connecting part 9. When the first connecting portion 1 and the second connecting portion 9 are switched between the first relative position and the second relative position, because the first position, the second position and the third position are located at different positions of the second outer connecting rod 5, the first middle connecting rod 4 is driven by the first connecting portion 1, and then the second outer connecting rod 5 is driven to rotate relative to the second connecting portion 9 along the second position thereof, and one end of the displacement connecting rod is hinged to the third position of the second outer connecting rod 5, and the other end of the displacement connecting rod is connected to the damping member 8, so that the rotational motion of the second outer connecting rod 5 is converted into the linear motion (sliding) of the displacement connecting rod, and then the damping member 8 can slide relative to the second connecting portion 9 under the driving of the displacement connecting rod, and the operation that the damping member 8 provides the damping force is realized.
Preferably, the angle between the first middle link 4 and the second outer link 5 is proportional to the angle between the first connecting portion 1 and the second connecting portion 9. That is, in the process of switching the first connecting portion 1 and the second connecting portion 9 between the first relative position and the second relative position, as the included angle between the first connecting portion 1 and the second connecting portion 9 is enlarged, the included angle between the first middle connecting rod 4 and the second outer connecting rod 5 is enlarged; the included angle between the first connecting part 1 and the second connecting part 9 is reduced, and the included angle between the first middle connecting rod 4 and the second outer connecting rod 5 is reduced. The included angle between the first connecting portion 1 and the second connecting portion 9 is an included angle formed by two oppositely arranged surfaces in a state that the two are located at the first relative position. An included angle between the first middle connecting rod 4 and the second outer connecting rod 5 is an included angle formed by two surfaces, close to each other, of the first middle connecting rod 4 and the second outer connecting rod 5 in a state that the first connecting part 1 and the second connecting part 9 are in the first relative position. In order to improve the rotational stability and ensure an effective provision of the damping force, the fourth position of the second outer link 5 is articulated with one of the rotational links of the rotational linkage; the fourth position is located at a different position of the second outer link 5 from the first position, the second position, and the third position. That is, the fourth position of the second outer link 5 is hinged to one of the pivotal links of the pivotal linkage, so that the second outer link 5 is also driven to pivot when the pivotal link is displaced. During the initial operation of switching the first connecting part 1 and the second connecting part 9 from the first relative position to the second relative position or switching the first connecting part 1 and the second connecting part 9 from the second relative position to the first relative position, the overall position of the rotating linkage is moved relative to the first connecting part 1 and the second connecting part 9, so that during the initial operation of switching, the hinge joint with one rotating connecting rod of the rotating linkage drives the second outer connecting rod 5 to rotate relative to the second connecting part 9 along the second position thereof by the hinge joint with the fourth position of the second outer connecting rod 5; and after the first middle connecting rod 4 rotates to a certain position relative to the first position of the second outer connecting rod 5, the second outer connecting rod 5 is continuously driven to rotate relative to the second connecting part 9 along the second position. That is, the second connecting portion 9 can be driven to rotate by both the first middle connecting rod 4 and one rotating connecting rod of the rotating linkage, so that the second outer connecting rod 5 can rotate relative to the second connecting portion 9 along the second position thereof in any process of switching the first connecting portion 1 and the second connecting portion 9 between the first relative position and the second relative position, so as to ensure that the damping member 8 provides effective damping force.
As shown in fig. 9, the second outer link 5 has a first position, a second position, a third position, and a fourth position, which are all hinged with other components. In the present embodiment, in order to avoid interference of components, the second outer link 5 has a rectangular parallelepiped structure, and the first position, the second position, the third position, and the fourth position are provided at four corners of one rectangular parallelepiped surface of the second outer link 5, respectively.

As shown in fig. 2 and 7, the first outer connecting rod 2 is an L-shaped connecting rod, and includes a first connecting rod portion 21 and a second connecting rod portion 22 connected to each other, wherein an end of the first connecting rod portion 21 away from the second connecting rod portion 22 is hinged to the first connecting portion 1, the first connecting rod portion 21 is hinged to the fourth position of the second outer connecting rod 5, and the second connecting rod portion 22 is hinged to the second inner connecting rod 3. Preferably, the hinge position of the second link portion 22 and the second inner link 3 is far away from the opposite surfaces of the first connecting portion 1 and the second connecting portion 9, and the opposite surfaces of the first connecting portion 1 and the second connecting portion 9 are surfaces on which the first connecting portion 1 and the second connecting portion 9 approach each other in the first relative position.
For the sake of stability, the number of the second outer links 5 is two, the second inner link 3 is located between the two second outer links 5, and the first middle link 4 is hinged to the first positions of the two second outer links 5. One end of the second inner link 3 is hinged to the second connecting portion 9, and the other end of the second inner link 3 passes through the hinged end of the first middle link 4 and the second outer link 5 (the first position of the second outer link 5) and is connected to the first outer link 2. In order to avoid the interference between the hinged ends of the first middle link 4 and the second outer link 5 and the second inner link 3, one surface of the second inner link 3 facing the hinged ends of the first middle link 4 and the second outer link 5 is a concave surface. Combining the first outer connecting rod 2 as an L-shaped connecting rod, the hinge position of the second connecting rod part 22 and the second inner connecting rod 3 is far away from the opposite surfaces of the first connecting part 1 and the second connecting part 9, so that the surface of the second inner connecting rod 3 facing the hinge end of the first middle connecting rod 4 and the second outer connecting rod 5 is far away from the hinge position of the first middle connecting rod 4 and the second outer connecting rod 5 as much as possible.
Furthermore, the number of the first outer connecting rods 2 is two, and the first outer connecting rods 2 are located at the outer sides of the two second outer connecting rods 5, wherein one first outer connecting rod 2 is hinged with one second outer connecting rod 5, and the other first outer connecting rod 2 is hinged with the other second outer connecting rod 5.

Wherein, be provided with the first articulated shaft of being connected with first well connecting rod 4 and the second articulated shaft of being connected with first outer connecting rod 2 between two first linking arms. Namely, the first hinge shaft and the second hinge shaft connected are supported by the two first connecting arms, ensuring stability in the process of hinge rotation.
As shown in fig. 1, 4 and 6, the connecting section of the second connecting portion 9 has two second connecting arms disposed opposite to each other, and the second inner link 3 is disposed between the two second connecting arms. The number of the second outer connecting rods 5 is two and the two outer connecting rods are respectively arranged on one side of the two second connecting arms which are relatively far away. Wherein, a third articulated shaft connected with the second inner connecting rod 3 and a fourth articulated shaft connected with the second outer connecting rod 5 are arranged between the two second connecting arms. Namely, the third hinge shaft and the fourth hinge shaft are supported by the two first connecting arms, so that the stability in the process of hinge rotation is ensured.
As shown in fig. 6, the second connecting portion 9 further has an embedded groove 91, and the body 81 of the damping member 8 is embedded in the embedded groove 91, which effectively improves the structural compactness.
For convenience of arrangement, the displacement connecting rod comprises a transmission connecting rod 6 and a driving connecting rod 7 which are hinged to each other, the transmission connecting rod 6 is hinged to a third position, and the driving connecting rod 7 is connected with a damping part 8. Through the arrangement, on the basis of converting the rotation of the second outer connecting rod 5 into the linear motion of the damping part 8, the connection between the driving connecting rod 7 and the damping part 8 is facilitated. The drive link 7 and the damping member 8 may be fixedly connected. Of course, in order to facilitate adjustment of the damping force, in this embodiment, the connection portion between the driving link 7 and the damping component 8 may be in threaded connection, so as to adjust the total length of the driving link 7 connected with the damping component 8, and further achieve the effect of adjusting the damping force.

Preferably, the bottom connecting arm has a threaded hole and the dampening coupling end 82 is a coupling screw mated therewith.
Of course, it is also possible to provide only the transmission link 6 and to connect the damping member 8 to the transmission link 6 in a hinged manner, i.e., it is necessary to provide a member such as a hinge hole or a hinge shaft at the connection between the damping member 8 and the transmission link 6.
