Example 2
As shown in fig. 1-8, the one-to-two gear clutch includes an output shaft 101, a driving gear 102, a driven gear 103 and a clutch structure.
The output shaft 101 is used to output the output torque of the power structure. The driving gear 102 is mounted on the output shaft 101, and the output shaft 101 rotates to drive the driving gear 102 to rotate. The driven gear 103 is used to connect the moving structure to transmit the output torque of the power structure. The clutch structure comprises a clutch gear 104 and a driving structure for driving the clutch gear 104 to generate displacement, when the clutch gear 104 is in a first position, the clutch gear 104 is simultaneously meshed with the driving gear 102 and the driven gear 103, and when the clutch gear 104 is in a second position, the clutch gear 104 is simultaneously separated from the driving gear 102 and the driven gear 103, and at the moment, the driving gear 102 is separated from the driven gear 103.
Specifically, the driving gear 102, the driven gear 103, and the clutch gear 104 are all cylindrical gears. The clutch gear 104 is mounted on a pinion shaft 105 and the clutch gear 104 consists of at least one cylindrical gear. When the clutch gear 104 is a cylindrical gear, one cylindrical gear corresponds to both the driving gear 102 and the driven gear 103, and when the clutch gear 104 is two or more cylindrical gears, at least one of the cylindrical gears corresponds to one of the driving gear 102 or the driven gear 103, and the other cylindrical gears correspond to two of the driving gear 102 or the driven gear 103.
The driving gear 102 and the driven gear 103 may be arranged in various ways, in this example, they are arranged in parallel, and the thickness of the clutch gear 104 is consistent with the total thickness of the driving gear 102 and the driven gear 103, so that the clutch gear 104 has a large meshing area with the driving gear 102 and the driven gear 103.
As an example, the driving structure includes: a gear carriage 106 and a displacement mechanism. Wherein the pinion shaft 105 is mounted on the gear sliding frame 106, and the clutch gear 104 is driven to move and provide support by the gear sliding frame 106. The displacement structure is connected to the gear carriage 106 to displace the clutch gear 104. Advantageously, the gear carriage 106 is connected to a first elastic member 107, the first elastic member 107 applying an elastic force or a tensile force to the gear carriage 106 away from the driving gear 102 and the driven gear 103. Specifically, the displacement structure includes a displacement member 108, a pressing member 109, a first fixing member 1012, and a second elastic member 1010. A sliding groove 1081 is formed in the displacement member 108, one end of the pressing member 109 is located in the sliding groove 1081, and the other end protrudes out of the sliding groove 1081. The first fixing member 1012 has a pressing surface 10121 and a stopping surface 10122, when the pressing member 109 slides to the pressing surface 10121, the pressing surface 10121 presses the pressing member 109 and the displacement member 108, so as to drive the clutch gear 104 to be located at the first position, when the pressing member 109 slides to the stopping surface 10122, the gear carriage 106 drives the displacement member 108 and the pressing member 109 to move upwards under the action of the first elastic member 107, so as to drive the clutch gear 104 to be located at the second position, and the stopping surface 10122 stops the pressing member 109 from moving towards the pressing surface 10121. The second elastic member 1010 applies an elastic force or a tensile force to the pressing member 109 sliding in the sliding groove 1081 to the pressing surface 10121 or the stopping surface 10122.
Specifically, the second elastic member 1010 is a spring and is disposed in the slide groove 1081. As shown, one end of the spring abuts against the sliding groove 1081, and the other end of the spring abuts against the pushing and pulling member 1011. The first elastic member 107 is a tension spring, which provides an upward tension to the gear sliding rack 106, and as shown in the figure, the lower end of the tension spring is connected to the gear sliding rack 106, and the upper end is connected to the gear fixing bracket 1013.
As an example, the displacement member 108 has a hinge end 1082 at one end for connecting a hinge point and a pressing end 1083 at the other end for rotating the displacement member 108 around the hinge point, and when the pressing end 1083 is pressed, the pressing member 109 can be slid to the pressing surface 10121.

As a preferred example, a push-pull member 1011 is further disposed in the sliding groove 1081, and the push-pull member 1011 is connected to the pressing member 109. The push-pull member 1011 is convenient to operate, and the using process is as follows: (1) when transmission is required, the pressing end 1083 of the displacement member 108 is pressed downward, and the displacement member 108 rotates downward around the hinge point, so as to drive the gear sliding frame 106 and the clutch gear 104 to move downward to the first position. Meanwhile, the pressing piece 109 moves downwards until the lower end of the first fixing piece 1012 (the upper transverse plate of the gear fixing bracket 1013), the pressing piece 109 slides the lower end of the pressing surface 10121 under the action of the second elastic piece 1010, and the clutch gear 104 protects the first position under the action of the pressing surface 10121, so that transmission is realized; (2) when the separation is needed, the pressing piece 109 is pushed outwards (when the pushing and pulling piece 1011 is pushed), so that the pressing piece 109 overcomes the elastic force of the second elastic piece 1010 and slides outwards along the sliding groove 1081 until the pressing piece 109 leaves the pressing surface 10121, the pressing effect of the pressing surface 10121 is lost, the gear sliding frame 106 moves upwards under the effect of the first elastic piece 107, the displacement piece 108 is driven to rotate upwards around the hinge point, the pressing piece 109 moves upwards, the stopping surface 10122 prevents the pressing piece 109 from moving towards the pressing surface 10121 until the clutch gear 104 is located at the second position, the second position is kept under the effect of the first elastic piece 107, the transmission is interrupted, and the separation is realized.
As a specific example, the gear fixing bracket 1013 is further included, and the gear fixing bracket 1013 is provided with an elongated sliding hole 10131, and the small toothed shaft 105 extends into the elongated sliding hole 10131. When the gear carriage 106 moves, the pinion shaft 105 moves along the elongated slide hole 10131.
As an application example, the side surface of the driven gear 103 is connected to the driving sprocket 21 through a plurality of shaft pads 1014, so that the sprocket chain transmission can be realized.
The application method of the one-drag two-gear clutch comprises the following steps:
when the driving structure drives the clutch gear 104 to be at the first position, the clutch gear 104 is simultaneously meshed with the driving gear 102 and the driven gear 103, and the driving gear 102 rotates to drive the moving structure to move; when the driving structure drives the clutch gear 104 to be in the second position, the clutch gear 104 is simultaneously separated from the driving gear 102 and the driven gear 103, at this time, the driving gear 102 is separated from the driven gear 103, and the driving gear 102 cannot drive the moving structure to move due to rotation.
