Detailed Implementation

[0033] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0035] like Figures 1 to 10 As shown, this application embodiment provides a dual-control switch, including: a base 1, the base 1 being an integral injection-molded structure, which is beneficial to improving the structural strength of the base 1;

[0036] Two sets of rocker assemblies are arranged side by side on the base 1, and are used to control the forward and reverse rotation of the motor respectively. Each rocker assembly includes a first rocker 2 and a first actuating element 7. The first rocker 2 is swayably connected to the base 1. The first actuating element 7 is located below the first rocker 2 and can swing with the first rocker 2 when the first rocker 2 swings. The first actuating element 7 is provided with a first moving contact 71. The base 1 is provided with a first stationary contact 8 at the corresponding position. When the first moving contact 71 contacts the first stationary contact 8, the motor runs.

[0037] The associated rocker plate 4 is arranged on the base 1 and can swing. The two ends of the associated rocker plate 4 are arranged corresponding to the first ends 201 of the two first rocker plates 2. The two ends of the first rocker plate 2 are the first end 201 and the second end 202. When the first end 201 of the first rocker plate 2 is pressed, the first movable contact 71 is in contact with the first fixed contact 8 to control the forward rotation or reverse rotation of the motor. When the second end 202 of the first rocker plate 2 is pressed, the first movable contact 71 is separated from the first fixed contact 8, and the motor stops.

[0038] The end of the associated rocker plate 4 is located below the first rocker plate 2. When the first end 201 of one of the first rocker plates 2 is pressed, the corresponding first movable contact 7 swings synchronously, so that the first movable contact 71 is in contact with the first fixed contact 8 to control the forward rotation or reverse rotation of the motor. At this time, the end of the associated rocker plate 4 below the first rocker plate 2 is pressed, and the other end of the associated rocker plate 4 is raised to synchronously raise the first end 201 of the other first rocker plate 2. The first movable contact 71 corresponding to the other first rocker plate 2 is separated from the first fixed contact 8, avoiding the simultaneous control of the two groups of associated rocker plates 4, and further avoiding the simultaneous forward rotation and reverse rotation of the motor, thereby preventing the motor from being damaged.

[0039] The base 1 is further sleeved with the shell 6, which protects and shields the internal structure of the base 1, avoiding the exposure of the electrical connection structure.

[0040] In some embodiments of the present application, the associated rocker plate 4 is arranged vertically with the first rocker plate 2. The two ends of the associated rocker plate 4 are arranged corresponding to the first ends 201 of the two first rocker plates 2. When the first end 201 of one of the first rocker plates 2 is pressed, the first end 201 of the other first rocker plate 2 is raised.

[0041] In some embodiments of the present application, the associated rocker plate 4 is made of metal material to prolong the service life of the associated rocker plate 4.

[0042] In some embodiments of the present application, the base 1 is provided with two first mounting grooves 11, and the rocker plate assembly is arranged one-to-one in the first mounting groove 11. The side wall of the first mounting groove 11 is provided with a first rotating part 101. The two side faces of the first rocker plate 2 corresponding to the side wall of the first mounting groove 11 are provided with a second rotating part 24. The second rotating part 24 is in rotating cooperation with the first rotating part 101.

[0043] Specifically, the base 1 is a frame structure. The first mounting groove 11 is surrounded by the frame. The number of the first mounting groove 11 is two. The rocker plate assembly is arranged one-to-one with the first mounting groove 11. The first rocker plate 2 and the side wall of the first mounting groove 11 are connected in rotation through the first rotating part 101 and the second rotating part 24 to enable the first rocker plate 2 to swing within a limited angle range.

[0044] In some embodiments of the present application, the first rotating part 101 comprises one of a first matching hole and a first matching protrusion, and the second rotating part 24 comprises the other of the first matching hole and the first matching protrusion.

[0045] For example, in some embodiments of the present application, the first rotating part 101 is a first matching hole formed on the side wall of the mounting groove, and the second rotating part 24 is a first matching protrusion formed on the side wall of the first flap 2. The upper surface of the base 1 is upwardly protruding to form a lug corresponding to the side wall of the first mounting groove 11, the first matching hole is formed on the lug, the first flap 2 is arranged corresponding to the first mounting groove 11, the first matching protrusion on the first flap 2 is inserted into the first matching hole and can rotate within the first matching hole by a certain angle, thereby realizing the swing of the first flap 2.

[0046] Of course, those skilled in the art can understand that in some embodiments, the first rotating part 101 is a first matching protrusion formed on the side wall of the mounting groove, and the second rotating part 24 is a first matching hole formed on the side wall of the first flap 2.

[0047] In some embodiments of the present application, the middle part of the first flap 2 is upwardly arched to form a first connecting section 21 and a first flap section 22 located at both ends of the first connecting section 21, and the lower part of the first connecting section 21 is provided with a first touch part 25, the side wall of the first mounting groove 11 is provided with a first limiting groove (not shown in the figure), and the side surface of the first touch part 7 is provided with a first limiting protrusion (not shown in the figure) matched with the first limiting groove, the first limiting protrusion is rotatably arranged in the first limiting groove, when the first end 201 of the first flap 2 is pressed down, the touch part 25 moves downward to press the first touch part 7, and the first moving contact 71 on the first touch part 7 is lifted to be separated from the first stationary contact 8.

[0048] Specifically, in combination with Figure 7As shown, in some embodiments of the present application, the lower surface of the first connecting section 21 is provided with a first mounting cylinder 23, which is open at one end away from the first connecting section 21, the actuating part 25 is a nylon contact, one end of which is movably inserted into the first mounting cylinder 23 and connected with the first mounting cylinder 23 through a spring, and the other end of the nylon contact extends out of the first mounting cylinder 23. When the first end 201 of the first flap 2 is pressed, the nylon contact moves downward synchronously with the first flap 2. The middle part of the first actuating part 7 is bent downward relative to the two ends of the first actuating part 7, and one end of the first actuating part 7 away from the first end 201 of the first flap 2 is provided with a movable contact. When the nylon contact moves downward, the end of the first actuating part 7 provided with the first movable contact 71 moves downward to contact the static contact, thereby achieving the effect of quickly connecting the current for the operation of the motor. When the second end 202 of the first flap 2 is pressed, the nylon contact moves upward, and the end of the first actuating part 7 provided with the movable contact is raised upward to move away from the static contact, thereby quickly disconnecting the current for the operation of the motor, and the motor is in a closed state.

[0049] The first limiting groove is located directly below the first matching hole. In some embodiments of the present application, the first limiting groove is a rectangular groove, and the first limiting protrusion is a rectangular block. The first limiting protrusion is located in the first limiting groove, so that the first actuating part 7 can only swing within a certain angle and cannot move, thereby improving the stability of the assembly structure.

[0050] In some embodiments of the present application, in combination with Figures 8 to 10 As shown, the associated flap 4 includes a second connecting section 41 with a middle part arched upward and second flap sections 42 located at both ends of the second connecting section 41. The base 1 is provided with an upper convex arc surface 103 at a position corresponding to the second connecting section 41. The lower surface of the second connecting section 41 is in contact with the arc surface 103, and the arc surface 103 forms a rotation fulcrum of the second connecting section 41.

[0051] Specifically, the second connecting section 41 is arranged on the arc surface 103 to form a flap structure, so as to realize the swinging of the associated flap 4. For example, in some embodiments of the present application, a triangular protruding structure is formed on the base 1, the upper end of the protruding structure is provided as the arc surface 103, and the second connecting section 41 is arranged on the arc surface 103, so that the associated flap 4 can swing left and right.

[0052] In some embodiments of the present application, a second limiting protrusion 411 is formed on the outer side wall of the second connecting section 41 in the width direction, and a second limiting groove 121 is formed on the corresponding position of the base 1. The second limiting protrusion 411 is rotatably arranged in the second limiting groove 121. Through the cooperation of the second limiting protrusion 411 and the second limiting groove 121, the associated flap 4 can be limited and swung within a certain angle.

[0053] Specifically, the base 1 is provided with a second mounting groove 12, the associated flap 4 is located in the second mounting groove 12, and a second limiting groove 121 is formed on the side wall of the second mounting groove 12. For example, in some embodiments of the present application, the second limiting groove 121 is a rectangular groove, the second limiting protrusion 411 is a rectangular block, the associated flap 4 is located in the second mounting groove 12, and the second limiting protrusion is inserted into the second limiting groove 121, so that the associated flap 4 can swing in the second mounting groove 12.

[0054] In some embodiments of the present application, the flap assembly further comprises a second flap 3, and each group of flap assemblies comprises two second flaps 3, which are respectively arranged at both ends of the first flap 2, that is, at the first end 201 and the second end 202 of the first flap 2. One end of the second flap 3 is rotationally connected to the base 1, and the other end is pressed against the end of the first flap 2. When the second flap 3 is pressed, the first end 201 of the first flap 2 is pressed down, and the first moving contact 71 and the first stationary contact 8 are brought into contact, thereby achieving the effect of quickly connecting the current for running the motor, and the motor rotates forward or reversely.

[0055] In some embodiments of the present application, in combination Figure 1 As shown, the double-control switch further comprises two switch buttons 5, which are respectively arranged above the two groups of flap assemblies. When one end of one switch button 5 is pressed, the second flap 3 is pressed down to press the first flap 2. The switch button 5 is used for operation to control the forward rotation, reverse rotation or stop of the motor.

[0056] Specifically, when one end of the switch button 5 on one side is pressed, the second flap 3 is swung, and the first flap 2 is swung to make the first moving contact 71 and the first stationary contact 8 come into contact with each other, thereby achieving the effect of quickly connecting the current for running the motor, and the motor rotates forward. At this time, the associated flap 4 swings, and the first end 201 of the switch button 5 on the other side is raised, avoiding simultaneous control of the forward rotation and reverse rotation of the motor. When it is needed to disconnect the current for running the motor, the other end of the switch button 5 on the same side is pressed to swing the corresponding second flap 3, and the first flap 2 is swung to the other side, so that the first moving contact 71 and the first stationary contact 8 are separated from each other, thereby achieving the effect of quickly disconnecting the current for running the motor, and the motor stops.

[0057] Similarly, pressing one end of the switch button 5 on the other side causes the second rocker 3 to swing, which in turn causes the first rocker 2 to swing, so that the first moving contact 71 and the first stationary contact 8 come into contact with each other, thereby quickly connecting the current for motor operation and causing the motor to reverse. At this time, the associated rocker 4 swings, and the first end 201 of the switch button 5 on the opposite side is lifted, preventing simultaneous control of the motor's forward and reverse rotation. When it is necessary to disconnect the motor's operating current, pressing the other end of the switch button 5 on the same side causes the corresponding second rocker 3 to swing, which in turn causes the first rocker 2 to swing to the other side, so that the first moving contact 71 and the first stationary contact 8 disengage, thereby quickly disconnecting the motor's operating current and stopping the motor.

[0058] Taking a two-way switch for controlling the opening and closing of curtains as an example, combined with... Figures 2 to 5 As shown, during use, the curtain motor is already rotated forward or reversed via the button assembly on one side. At this time, the pressing side of the associated rocker arm 4 is close to the base 1 (left lower, right higher). When the user directly presses the switch button 5 on the other side, the plastic second rocker arm 3 on the same side swings, and the moving contact of the first rocker arm 2 on the same side abuts against the corresponding stationary contact. Simultaneously, due to the downward movement of the moving contact of the first rocker arm 2 on the same side abutting against the corresponding stationary contact, the associated rocker arm 4 swings. The pressing side of the associated rocker arm 4 on this side is close to the base 1210 (left higher, right lower). The first rocker arm 2 on the other side swings due to the rocker movement of the associated rocker arm 4, so that the moving contact of the first rocker arm 2 moves away from the corresponding stationary contact, thereby quickly disconnecting the current for the motor and achieving a stop state. In other words, when one switch button 5 controls the motor to rotate forward or reverse, the control circuit of the other switch button 5 is disconnected, avoiding simultaneous control of the curtain motor to rotate forward and reverse.

[0059] By applying this two-way switch to curtains, the direction of curtain movement can be controlled through a single two-way switch, thus enabling the curtains to be opened and closed.
