Detailed Description

The invention is further described below with reference to the accompanying drawings.

The double-drive switch of the present invention, as shown in fig. 1 to 3, comprises a switch module 2, as shown in fig. 6 to 8, the switch module 2 is provided with a movable contact seesaw 21 and a swing block 27 for driving the movable contact seesaw 21, specifically, the switch module 2 further comprises a wiring device 25, the wiring device 25 is connected with the corresponding stationary contact 23 or common contact 24, for example, the switch module 2 shown in fig. 8 is provided with three wiring devices 25, as shown in fig. 6, two wiring devices 25 are respectively connected with the corresponding stationary contact 23, the other wiring device 25 is connected with the common contact 24, the common contact 24 is used as a swing fulcrum of the movable contact seesaw 21, more specifically, as shown in fig. 9, the swing block 27 is formed with a cover cavity 273, one end of the cover cavity 273 is closed, as shown in fig. 6, a pull tongue 22 is slidably connected in the cover cavity 273, a spring 26 is arranged between the shifting tongue 22 and the bottom of the cover cavity 273; as shown in fig. 6, then when the swing block 27 swings, the shifting tongue 22 swings following the swing block 27, the tip of the shifting tongue 22 is kept pressed on the movable contact seesaw 21 by the elastic force of the spring 26, in the process that the tip of the shifting tongue 22 swings from the upper side of the common contact 24 to the lower side of the common contact 24 in the visual direction of fig. 6, the shifting tongue 22 retracts first, and the spring 26 is further elastically compressed and deformed, after the tip of the shifting tongue 22 slides over the position opposite to the common contact 24, the elastic force of the spring 26 pushes out the shifting tongue 22, so that the shifting tongue 22 can push the movable contact seesaw 21 to swing clockwise to be switched to be contacted with the fixed contact 23 at the lower position, and the movable contact seesaw 21 is kept pressed on the corresponding fixed contact 23 by the elastic force of the spring 26, thereby ensuring that the movable contact seesaw 21 is well contacted with the corresponding fixed contact 23; the foregoing description is of the prior art and is not material to the present invention, and therefore, will not be described in detail.

As shown in fig. 1 to 6, the switch of the present invention further includes a switch plate 4 that swings coaxially with the swing block 27, as shown in fig. 9 and 10, the swing block 27 is formed with wing plates 271 distributed on both sides of the swing axis of the swing block 27, the axis of the first protruding pin 272 shown in fig. 10 is the swing axis of the swing block 27, as shown in fig. 6, the wing plates 271 are in abutting connection with the back of the switch plate 4, as shown in fig. 9, 11 and 12, the swing block 27 is formed with a connection hole 274, as shown in fig. 15, the back of the switch plate 4 is formed with a driving lever 41, and as shown in fig. 5 and 6, the driving lever 41 is in fitting connection with the connection hole 274. As shown in fig. 6, in the case that the relative installation position of the swing block 27 and the switch board 4 is accurate, since the wing plate 271 is in abutting connection with the back of the switch board 4, the swinging block 27 can be driven to swing by pressing the switch board 4 with fingers, thereby realizing the switch operation, and, assuming that, when a large error occurs in the relative mounting position of the swing block 27 and the switch plate 4, the switch plate 4 is caused to move away from the wing plate 271, however, since the driver 41 is fittingly coupled to the coupling hole 274, the driver 41 and the switch plate 4 are swung together in synchronization, so that the driver 41 can still pull the swing block 27, therefore, the switch operation is realized, the double driving of the switch is realized by arranging two structures of the driving deflector rod 41 and the part of the switch plate 4 which can be contacted with the wing plate 271 and driving the swinging block 27, so that the switch has good adaptability to the installation environment and stable working performance.

Further, as shown in fig. 12 and 13, an inner notch 2741 is formed in the connecting hole 274, specifically, in the visual direction of fig. 13, an upper bell mouth portion 2742 and a lower bell mouth portion 2743 are formed on the inner wall of the connecting hole 274, and an inner notch 2741 is formed at the connection point of the upper bell mouth portion 2742 and the lower bell mouth portion 2743, as shown in fig. 14, the rear end portion of the driver rod 41 is in fit and contact with the inner notch 2741 (the "rear end portion" is for a user standing right in front of the switch), as can be seen from fig. 14, by providing the inner notch 2741, the contact area between the driver rod 41 and the swing block 27 is greatly reduced, and when there is a large mounting position error between the driver rod 41 and the swing block 27, the mounting position error can be compensated by elastic deformation of the driver rod 41, in other words, the upper bell mouth portion 2742 and the lower bell mouth portion 2743 provide a space for relative displacement of the driver rod 41, the driver 41 and the swing block 27 are relatively moved during the swing due to the above-mentioned mounting position error, but since the contact area between the driver 41 and the swing block 27 is small, the friction force between the driver 41 and the swing block 27 is also reduced, which is advantageous for the flexible operation of the transmission mechanism from the switch board 4 to the movable contact rocker 21.

Further, as shown in fig. 15, a support plate 411 is formed at the front end of the driver rod 41, the front end of the support plate 411 is connected to the back surface of the switch plate 4, and the support plate 411, the driver rod 41, and the switch plate 4 are integrally provided, thereby facilitating the enhancement of the bending resistance of the driver rod 41 and preventing the driver rod 41 from being easily broken.

Further, as shown in fig. 15, a rib plate 42 is formed at the back of the switch board 4, and the rib plate 42 is beneficial to enhancing the strength of the switch board 4, so as to prevent the switch board 4 from being easily bent and deformed or from being broken in the use process, as shown in fig. 6 and 14, the rib plate 42 is connected with the corresponding wing plate 271 in an abutting manner, and because the strength of the rib plate 42 is high, even if the rib plate 42 is impacted by the wing plate 271 for many times, the switch board 4 is not broken and damaged in the long-term use process of the switch.
