Detailed Description

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 some, not all, embodiments of the present invention. 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.

Referring to fig. 1 to 8, fig. 1 is a schematic perspective view of a connection assembly according to an embodiment of the present invention, and as shown in fig. 1, the connection assembly includes:

a base 10, wherein the base 10 includes a base body 11, a first connecting rod 12 and a second connecting rod 13, the first connecting rod 12 has a linear connection portion 121, the second connecting rod 13 has a first connection portion 131, and the linear connection portion 121 of the first connecting rod 12 is opposite to and perpendicular to the first connection portion 131 of the second connecting rod 13;

the bevel gear 20 is arranged on the linear connecting part 121 of the first connecting rod 12 in a penetrating way;

a spur gear 30, wherein the spur gear 30 is arranged on the first connecting portion 131 of the second connecting rod 13 in a penetrating manner, the helical gear 20 is engaged with the spur gear 30, and the helical gear 20 is positioned between the spur gear 30 and the base body 11;

and a rocker 40, wherein the rocker 40 is arranged on the spur gear 30 and rotates along with the rotation of the spur gear 30.

It should be noted that the connection assembly in the embodiment of the present application may be applied to an electronic device.

The working principle of the embodiment can be referred to as the following expression:

because the helical gear 20 is meshed with the spur gear 30, the helical gear 20 can drive the spur gear 30 to rotate, and further drive the rocker 40 to rotate, and the rocker 40 can be connected with a driven component (such as a screen or other components) so as to realize the rotation of the rocker 40 and further realize the driving of the driven component.

Meanwhile, due to the structural particularity of the helical gear 20 and the spur gear 30, when the helical gear 20 drives the spur gear 30 to move, the spur gear 30 can have displacement in the Y-axis direction as shown in fig. 1 or fig. 4, and further can drive the rocker 40 to rotate along the Y-axis direction, so that the rotation range of the rocker 40 is enlarged, and the rotation effect of the rocker 40 is enhanced. When the connecting assembly is applied to the electronic equipment, the folding amplitude or the bending amplitude of the electronic equipment can be larger, namely the folding or bending effect is better.

It should be noted that, because the helical gear 20 is engaged with the spur gear 30, after the helical gear 20 drives the spur gear 30 to move to a certain position along the first direction, the helical gear 20 can have a locking function for the spur gear 30, so as to prevent the spur gear 30 from rotating in a direction opposite to the first direction.

For example: after the helical gear 20 drives the spur gear 30 to rotate clockwise and the helical gear 20 drives the spur gear 30 to rotate to the first position, the spur gear 30 needs to be kept at the first position, even if the spur gear 30 (or the rocker 40) is subjected to an acting force which enables the spur gear 30 to rotate counterclockwise, the helical gear 20 has a limiting effect on the spur gear 30, and at this time, the spur gear 30 can be always located at the first position.

Referring to fig. 1, the first connecting rod 12 may include two first supporting portions 122, the two first supporting portions 122 may be respectively fixed to opposite ends of the base body 11, and two ends of the linear connecting portion 121 may be respectively connected to the two first supporting portions 122, so that the linear connecting portion 121 may be supported.

Similarly, referring to fig. 1, the second connecting rod 13 may include two second supporting portions 132, the two second supporting portions 132 may be respectively fixed to two opposite ends of the base body 11, and two ends of the first connecting portion 131 may be respectively connected to the two second supporting portions 132, so that the first connecting portion 131 may be supported. It should be noted that a first line between the two first supporting portions 122 and a second line between the two second supporting portions 132 may be perpendicular.

In addition, the linear connection portion 121 is closer to the base body 11 than the first connection portion 131, that is, the distance between the linear connection portion 121 and the base body 11 is smaller than the distance between the first connection portion 131 and the base body 11, and it can also be understood that the height of the first connection portion 131 is higher than the height of the linear connection portion 121.

In addition, it should be noted that a power module may also be disposed in the base 10, and the power module is used for supplying power to each component in the connection assembly. And the spur gear 30 may be provided with a through hole, a connector 31 may be provided in the through hole, and the power module may be electrically connected to the connector 31 for supplying power to the connector 31. The connector 31 may be a bipolar ball connector. When a plurality of connecting assemblies are connected in sequence, two adjacent connecting assemblies can be electrically connected through the bipolar ball connector, and the corresponding position of the bipolar ball connector can also be called as a cascade bipolar interface.

It should be noted that the helical gear 20 may be rotated by driving the helical gear 20 to rotate under the action of an external force applied by a user. Of course, the rotation can also be performed by the driving action of the driving member.

For example, as an alternative embodiment, the connecting assembly further comprises a motor, the motor is connected with the bevel gear 20, and the motor drives the bevel gear 20 to rotate around the linear connection part 121 of the first connecting rod 12. Thus, the bevel gear 20 can be driven to rotate by the motor, so that the accuracy of the driving position of the bevel gear 20 is improved, and the driving effect of the bevel gear 20 is enhanced.

The motor may be disposed on the first supporting portion 122, or certainly, may be disposed in a cavity inside the base body 11, and then electrically connected to the helical gear 20 through an electrical connection line to drive the helical gear 20 to rotate. The electrical connection circuit can be embedded in the wiring channel inside the first supporting portion 122, so that the electrical connection circuit can be protected.

Optionally, the helical gear 20, the spur gear 30 and the rocker 40 are disposed on a first side of the base 10, referring to fig. 2 to 8, a first connecting structure 41 is disposed on the rocker 40, a second connecting structure 42 is disposed on a second side of the base 10, and the first connecting structure 41 is adapted to the second connecting structure 42.

For example: after cascading through a plurality of coupling assembling, can form chain structure, this chain structure can be programme-controlled, deflects various angles, realizes the deformation of 2D state, for example: the maximum angle of rotation of the connection assembly is 20 degrees. When the connecting assemblies are applied to electronic equipment (such as a mobile phone), the whole mobile phone can be calculated according to 130 mm, 46 connecting assemblies can be connected in a cascade mode, and the theoretical rotation angle 46 multiplied by 20 is 920 degrees and can rotate for about two and a half cycles; in addition, the maximum rotation angle of the rocker 40 in the connecting assembly and the length of the connecting assembly can be optimized, and a larger rotation angle of the cascaded chain structure is realized.
