Detailed Description
The technical scheme of the present application is further elaborated below with reference to the drawings and specific embodiments. The shape, size, etc. of each structure in the drawings are merely illustrative of the embodiments of the present application, and are not limiting on the structure.
For a better understanding of the embodiments of the present application, a description will be first given of a connection structure commonly used in the related art.
The traditional gears, especially the pinion gear used for transmission in the middle, are stressed on one side at the gear teeth side, and the strength is challenged because the gears of light and thin machine types are smaller and smaller. Fig. 1 is a schematic diagram of the composition of gears for transmission in the related art, and as shown in fig. 1, the transmission in the related art is generally divided into a spindle gear 11 and an MIM (Metal Injection Molding, metal injection molded) gear 12. The rotating shaft gear 11 or the MIM gear 12 has only one meshing surface, and the gear teeth on the gears are stressed unidirectionally in the process of transmitting the rotation force, for example, when the rotating shaft gear 11 or the MIM gear 12 is meshed with other gears to operate, the single gear teeth are subjected to force F in a single direction. Also, when the MIM gear 12 is used as a transmission gear, both single teeth at both radial ends thereof receive forces in a single direction, respectively. Therefore, when the gear ruler is used, the single face of the gear ruler is stressed, and the risk of tooth breakage is high.
The embodiment of the application provides a connection structure, which can be applied to electronic equipment, wherein the electronic equipment comprises a first body, a second body and the connection structure. For example, fig. 2A is a schematic diagram of a position of the connection structure in the electronic device according to the embodiment of the present application, in an implementation process, as shown in fig. 2A, the electronic device may be a notebook computer, correspondingly, the first body 21 may be a portion where a display screen on the notebook computer is located, and the second body 22 may be a portion of a body with a keyboard on the notebook computer, where the display screen and the body with the keyboard on the notebook computer are connected into a whole through the connection structure 23.
Fig. 2B is a schematic diagram of the composition structure of the connection structure according to the embodiment of the present application, as shown in fig. 2B, where the connection structure includes:
the first rotating means 21 comprises a first gear 211 at a first end thereof;
here, the first rotating device 21 further includes a first rotating shaft 212, and the first gear 211 rotates in a direction of a rotating surface of the first rotating shaft 212. The first rotating device 21 further includes a first fixing member 213, where the first fixing member 213 includes a fixing frame and a fixing piece, the fixing frame is provided with more than one first through hole, and the fixing piece fixes the fixing frame at the first end of the first rotating shaft 212 through the first through hole; the fixing frame is also provided with more than one second through hole, and the fixing piece fixes the fixing frame on the first body of the electronic equipment through the second through hole.

The transmission device 23 is simultaneously meshed with the first gear 211 and the second gear 221, so that the rotation of the first rotation device 21 can be transmitted to the second rotation device 22.
In this embodiment, when the first rotating device 21 starts to rotate, the rotating force can be transmitted to the transmission device 23 through the engagement with the transmission device 23. The transmission device 23 starts to rotate along the direction of the rotation surface of the transmission shaft, and is meshed with the second rotation device 22 to drive the second rotation device 22 to rotate, so that continuous meshing transmission of motion and power is realized.
The connection structure provided in the embodiment of the application includes: a first rotating device including a first gear at a first end thereof; a second rotating device including a second gear at a first end thereof; the transmission device is meshed with the first gear and the second gear simultaneously, so that the rotation of the first rotation device can be transmitted to the second rotation device; in this way, compared with the two teeth at the two radial ends of the transmission device (such as the MIM gear 12 in fig. 1) in the related art, the force applied to the transmission device can be reduced, thereby reducing the requirement on the material of the connection structure, reducing the manufacturing difficulty and prolonging the service life of the connection structure.
Based on the foregoing embodiments, the present embodiment further provides a connection structure, and fig. 2C is a schematic diagram of a composition structure of the connection structure according to the embodiment of the present application, as shown in fig. 2C, where the connection structure includes:

a second rotating means 22 comprising a second gear at a first end thereof;
and a transmission device 23 which is meshed with the first gear and the second gear simultaneously, so that the rotation of the first rotation device can be transmitted to the second rotation device.

In this way, the force F in the first direction and the force N in the second direction are forces acting on the first transmission structure that meet the relative condition, so that the resultant force to which the first transmission structure is subjected is smaller than both the force F in the first direction and the force N in the second direction.
In some embodiments, when the transmission device is operated to a certain extent, the force F in the first direction and the force N in the second direction may be the same, so that the force resultant force of the first transmission structure is 0, and only a small strength is theoretically required to meet the design requirement.
