Description

Technical Field

[0001] The utility model relates to the field of transmission structures, in particular to a transmission component in which a guide rail and a gear cooperate. Background Art

[0002] In the field of mechanical structure, the connecting rod mainly plays the role of power transmission, and the end of the connecting rod will be connected to the force-bearing parts. In order to facilitate the conversion of the rotational power of the motor or handle into the horizontal reciprocating thrust of the connecting rod, a crank-connecting rod structure will be installed between the motor or handle and the connecting rod. The crank-connecting rod structure mainly plays the role of torque transmission. The current crank-connecting rod structure mainly includes gears, pins installed on the side of the gears, cranks hinged to the pins, and connecting rods hinged at the ends of the cranks. When the motor or handle drives the gears to rotate, the crank drives the connecting rod to perform telescopic operation. In actual use, it is found that when the current crank-connecting rod structure drives the connecting rod to perform telescopic swinging operation, the overall strength of the crank structure is weak, and the crank-connecting rod structure is prone to shaking during operation. Utility Model Content

[0003] The purpose of the utility model is to solve the defects of the prior art and provide a transmission assembly in which a guide rail and a gear cooperate.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A transmission assembly in which a guide rail and a gear cooperate, comprises a mounting frame, a gear driving assembly arranged on one side of the mounting frame, a guide rail assembly cooperating with the gear driving assembly, and a transmission plate mounted on one side of the guide rail assembly. The gear driving assembly comprises a driving motor mounted on one side of the mounting frame, a driving gear connected to the driving motor, and a driven gear meshing with the driving gear. The driving gear and the driven gear are rotatably mounted on the mounting frame. The middle part of the driven gear is connected to a rocker arm, a slide groove is provided on the rocker arm, a connecting arm is slidably mounted in the slide groove, a guide roller is provided at the end of the connecting arm, a guide groove is provided on the back side of the mounting frame, and the guide roller is installed in the guide groove.

[0006] Furthermore, the guide rail assembly includes a longitudinal guide rail connected to the end of the connecting arm, a longitudinal slider slidably mounted on the longitudinal guide rail, a transverse slider fixedly mounted on the longitudinal slider, and a transverse guide rail slidably matched with the transverse slider.

[0007] Furthermore, the transmission plate is mounted on an end of the longitudinal guide rail away from the connecting arm, and the transverse guide rail is mounted on the mounting frame through a supporting frame.

[0008] Furthermore, the installation directions of the transverse guide rail and the longitudinal guide rail are perpendicular.

[0009] Furthermore, the slide groove extends in the length direction of the rocker arm.

[0010] Furthermore, the guide groove is in an "n" shape.

[0011] The beneficial effects of the utility model are as follows: when the transmission assembly is in use, the driving motor drives the driving gear to rotate, the driving gear drives the driven gear to rotate, and the driven gear drives the rocker arm to rotate. During the rotation of the rocker arm, the rocker arm drives the guide roller to move in the guide groove. During the movement of the guide roller, the connecting arm moves along the trajectory of the guide groove. During the movement of the connecting arm, its longitudinal movement trajectory is guided by the movement of the longitudinal guide rail on the longitudinal slider, and the lateral movement trajectory of the connecting arm is guided by the movement of the lateral slider on the lateral guide rail, thereby ensuring that the connecting arm moves stably along the trajectory of the guide groove. When the connecting arm moves, it also drives the transmission plate to move with it, and the movement trajectory of the transmission plate is consistent with the trajectory of the guide groove. This structure guides the movement of the transmission plate smoothly through the guide rail assembly, and the movement trajectory of the transmission plate can be flexibly changed through the direction of the guide groove. The transmission plate is convenient to adjust the running trajectory and runs smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] When the transmission assembly is in use, the driving motor 3 drives the driving gear 4 to rotate, the driving gear 4 drives the driven gear 5 to rotate, and the driven gear 5 drives the rocking arm 6 to rotate. During the rotation of the rocking arm 6, the rocking arm 6 drives the guide roller 9 to move in the guide groove 10. During the movement of the guide roller 9, the connecting arm 8 moves along the trajectory of the guide groove 10. During the movement of the connecting arm 8, the trajectory of its longitudinal movement is guided by the movement of the longitudinal guide rail 11 on the longitudinal slider 12, and the trajectory of the lateral movement of the connecting arm 8 is guided by the movement of the lateral slider 13 on the lateral guide rail 14, thereby ensuring that the connecting arm 8 moves stably along the trajectory of the guide groove 10.
