[0024] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0025] like Figures 1 to 6 As shown, the present invention provides a manual and electric switching double terminal conversion switch, which includes a base 1, a left paddle 2 slidably arranged on the base 1, a right paddle 3 slidably arranged on the base 1, and a driving mechanism for driving the left paddle 2 and the right paddle 3 to move, wherein the driving mechanism includes a rotating driver 41 installed on the base 1, a cam plate 42 rotatably arranged on the base 1, a left driving component 43 installed on the cam plate 42 and used to drive the left paddle 2 to move, a right driving component installed on the cam plate 42 and used to drive the right paddle 3 to move, a control unit 45 installed on the base 1 and electrically connected to the rotating driver 41, and an output shaft 46 lifted and arranged on the rotating driver 41 and used to open and close the control unit. The control unit 45 includes a starting member 47 and an output shaft 46 installed on the rotation driver 41 and used to drive the starting member 47 to rise and fall. The control unit 45 is used to control the opening and closing of the rotation driver 41. The output shaft 46 of the rotation driver 41 is used to drive the control component to rotate synchronously with the cam plate 42. Specifically, the base 1 is equipped with a left power supply 5 and a right power supply 51, and the left power supply 5 and the right power supply 51 are respectively provided with a left switch and a right switch. The end of the left paddle 2 away from the right paddle 3 is connected to the left switch, and the end of the right paddle 3 away from the left paddle 2 is connected to the right switch. The control unit 45 is electrically connected to an external device. Preferably, the rotation driver 41 is a motor.

[0026] In actual application, the present invention is installed in a dual power supply device, and the left power supply 5 and the right power supply 51 are both used to supply power to the dual power supply device, assuming that the left power supply 5 is a common power supply and the right power supply 51 is a backup power supply. When the control assembly drives the starter 47 to rise, the rising starter 47 starts the control unit 45, and the started control unit 45 powers on the rotation driver 41, so that the present invention is in an electric state. When the left power supply 5 needs to be used to supply power to the dual power supply device, the output shaft 46 of the rotary driver 41 rotates, and the rotating output shaft 46 drives the cam plate 42 and the control assembly to rotate counterclockwise synchronously. The counterclockwise rotating cam plate 42 drives the left drive assembly 43 and the right drive assembly to rotate counterclockwise synchronously around the central axis of the cam plate 42, and the counterclockwise rotating left drive assembly 43 resists the left paddle 2 to move forward, and the forward moving left paddle 2 drives the left switch of the left power supply 5 to swing forward, so that the left switch is in the starting state, so that the left power supply 5 is in the starting state, and the left power supply 5 supplies power to the dual power supply device; at the same time, the counterclockwise rotating right drive assembly resists the right paddle 3 to move backward, and the backward moving right paddle 3 drives the right switch of the right power supply 51 to swing backward, so that the right switch is in the off state, so that the right power supply 51 is in the off state, and the right power supply 51 stops supplying power to the dual power supply device; in the reverse operation, the left power supply 5 is in the off state, and the right power supply 51 is in the starting state. When the manipulation assembly drives the starter 47 to descend, the descending starter 47 turns off the control unit 45, and the turned-off control unit 45 cuts off the power to the rotary drive 41, thereby putting the present invention in a manual state. When the left power supply 5 needs to be used to supply power to the dual power supply device, the control component is manually rotated counterclockwise, and the counterclockwise rotating control component drives the output shaft 46 of the rotating driver 41 to rotate counterclockwise, and the counterclockwise rotating output shaft 46 of the rotating driver 41 drives the cam plate 42 to rotate counterclockwise, and the counterclockwise rotating cam plate 42 drives the left driving component 43 and the right driving component to rotate counterclockwise around the central axis of the cam plate 42 synchronously, and the counterclockwise rotating left driving component 43 resists the left paddle 2 to move forward, and the forward moving left paddle 2 drives the left switch of the left power supply 5 to swing forward, so that the left switch is in the starting state, so that the left power supply 5 is in the starting state, and the left power supply 5 supplies power to the dual power supply device; at the same time, the counterclockwise rotating right driving component resists the right paddle 3 to move backward, and the backward moving right paddle 3 drives the right switch of the right power supply 51 to swing backward, so that the right switch is in the off state, so that the right power supply 51 is in the off state, and the right power supply 51 stops supplying power to the dual power supply device; in the reverse operation, the left power supply 5 is in the off state, and the right power supply 51 is in the starting state.

[0027] Compared with the existing conversion switches, which require additional buttons and components to achieve manual and electric switching, and also require the storage of additional components, are cumbersome to operate, have a complex structure, and are large in size, the structure of the present invention is simple and compact, not only can it perform conversion control on the opening and closing of dual power supplies or dual terminals, but also integrate manual control and electric control together, so that manual control or electric control can be selected according to actual needs. The switching between manual and electric is convenient and fast, and no additional buttons and components need to be added, which simplifies the operation process and improves the operation efficiency. The manual state and the electric state are interlocked with each other, which avoids the risk of operation and improves the safety performance of operation.

[0028] In this embodiment, the left drive assembly 43 includes a first left drive block 431 and a second left drive block 432, and the right drive assembly includes a first right drive block 441 and a second right drive block 442. The first left drive block 431 and the second left drive block 432 are respectively located on both sides of the left paddle 2, and the first right drive block 441 and the second right drive block 442 are respectively located on both sides of the right paddle 3.

[0029] In actual application, when the left power source 5 needs to be started, the counterclockwise rotating cam disc 42 drives the left driving assembly 43 and the right driving assembly to rotate counterclockwise around the central axis of the cam disc 42 synchronously, so that the second left driving block 432 rotates away from the left paddle 2, and the first left driving block 431 contacts one side of the left paddle 2 and drives the left paddle 2 to move forward, until the forward-moving left paddle 2 swings the left switch of the left power source 5 forward, so that the left power source 5 is started; at the same time, the first right driving block 441 rotates away from the right paddle 3, and the second right driving block 442 contacts one side of the right paddle 3 and drives the right paddle 3 to move backward, until the backward-moving right paddle 3 swings the right switch of the right power source 51 backward, so that the right power source 51 is turned off. The reverse operation can start the right power source 51.

[0030] In this embodiment, the cam plate 42 includes an arc portion 421, an elliptical portion 422 and two transition portions 423, one end of the arc portion 421 is connected to one end of the elliptical portion 422 via a transition portion 423, the other end of the arc portion 421 is connected to the other end of the elliptical portion 422 via another transition portion 423, the first left driving block 431 and the first right driving block 441 are arranged on the arc portion 421 and are symmetrically arranged about the horizontal center line a of the arc portion 421, the second left driving block 432 and the second right driving block 442 are arranged on the elliptical portion 422 and are symmetrically arranged about the horizontal center line b of the elliptical portion 422; specifically, the horizontal center line a and the horizontal center line b are arranged in a colinear manner, and the cam plate 42 is a left-right symmetrical structure. The cam plate 42 with this structural design makes the left driving component 43 and the right driving component drive the left paddle 2 and the right paddle 3 to move synchronously, respectively, and can accurately switch the left power supply 5 and the right power supply 51.

[0031] In this embodiment, the end of the left paddle 2 close to the right paddle 3 is provided with a left slide groove 21 for accommodating the first left drive block 431 and a left contact surface 22 for contacting the second left drive block 432; the end of the right paddle 3 close to the left paddle 2 is provided with a right slide groove 31 for accommodating the first right drive block 441 and a right contact surface 32 for contacting the second right drive block 442.

[0032] In actual application, when the left power source 5 needs to be started, the counterclockwise rotating cam disc 42 drives the left driving assembly 43 and the right driving assembly to rotate counterclockwise around the central axis of the cam disc 42 synchronously, so that the second left driving block 432 rotates away from the left contact surface 22, and the first left driving block 431 rotates into the left slide groove 21 and contacts the inner wall of the left slide groove 21, thereby pushing the left paddle 2 forward until the forward-moving left paddle 2 swings the left switch of the left power source 5 forward, so that the left power source 5 is started; at the same time, the first right driving block 441 rotates away from the right slide groove 31, and the second right driving block 442 contacts the right contact surface 32 of the right paddle 3 and pushes the right paddle 3 to move backward until the backward-moving right paddle 3 swings the right switch of the right power source 51 backward, so that the right power source 51 is turned off. The right power source 51 can be started by reverse operation. On the contrary, the first left driving block 431 rotates away from the left slide groove 21, the second left driving block 432 contacts the left contact surface 22 and pushes the left paddle 2 to move backward, the first right driving block 441 rotates into the right slide groove 31 and contacts the inner wall of the right slide groove 31, thereby pushing the right paddle 3 to move forward, and the second right driving block 442 rotates away from the right contact surface 32. By adding the left slide groove 21, the left contact surface 22, the right slide groove 31 and the right contact surface 32, the stability of the left driving assembly 43 driving the left paddle 2 to move and the right driving assembly driving the right paddle 3 to move is improved.

[0033] Specifically, the first left driving block 431, the second left driving block 432, the first right driving block 441 and the second right driving block 442 are all cylindrical, and a side wall of the left slide groove 21 close to the first left driving block 431 is provided with a left guide inclined surface 23, and the left guide inclined surface 23 is communicated with the left slide groove 21. When the first left driving block 431 rotates counterclockwise, the first left driving block 431 enters the left slide groove 21 along the left guide inclined surface 23, so that the first left driving block 431 drives the left paddle 2 to move; a side wall of the right slide groove 31 close to the first right driving block 441 is provided with a right guide inclined surface 33, and the right guide inclined surface 33 is communicated with the right slide groove 31. When the first right driving block 441 rotates clockwise, the first right driving block 441 enters the right slide groove 31 along the right guide inclined surface 33, so that the first right driving block 441 drives the right paddle 3 to move.

[0034] In this embodiment, the control assembly includes an elastic member 481 disposed between the cam plate 42 and the starter 47 and a handle 482 rotatably disposed on the output shaft 46 of the rotary driver 41 , and the handle 482 is used to drive the starter 47 to rise and fall.

[0035] When the handle 482 is in a horizontal state, the elastic force of the elastic member 481 makes the starter 47 in the highest position, the starter 47 triggers the control unit 45 to start, so that the rotary drive 41 is powered on, and the present invention is in an electric state; when the present invention needs to be switched to a manual state, the handle 482 only needs to be rotated so that the handle 482 is in a vertical state, and the bottom end of the handle 482 presses down the starter 47, so that the starter 47 compresses the elastic member 481 and descends, until the starter 47 is in the lowest position, the starter 47 triggers the control unit 45 to close, so that the rotary drive 41 is powered off, and the present invention is in a manual state. When the present invention needs to be switched back to an electric state, the handle 482 only needs to be rotated in the opposite direction so that the handle 482 is in a horizontal state, and the bottom end of the handle 482 releases the downward pressure on the starter 47, and the starter 47 rises under the action of the rebound force of the elastic member 481 until the starter 47 is in the highest position, and the starter 47 triggers the control unit 45 to work, so that the rotary drive 41 is powered on, and the present invention is in an electric state. The control component of this structural design makes the switching between the manual state and the electric state convenient and quick.

[0036] Specifically, the elastic member 481 is a spring, which has a simple structure, is easy to disassemble and maintain, has low cost, good elasticity and a long service life; the spring is sleeved outside the output shaft 46 of the rotary driver 41, and the output shaft 46 guides and limits the spring to prevent the spring from bending or tilting under pressure, thereby ensuring that the spring can work normally; a fixing hole is provided at the bottom of the starting member 47, one end of the spring is inserted into the fixing hole, and the other end of the spring contacts the cam plate 42, and the fixing hole positions the spring, which facilitates the assembly of the spring and improves the stability of the spring.

[0037] In this embodiment, the handle 482 includes a rotating plate 483 rotatably arranged on the output shaft 46 of the rotating driver 41 and a pressing member 484 connected to the rotating plate 483, and the rotating plate 483 and the pressing member 484 are arranged in the same plane; when the rotating plate 483 is in a vertical state, the pressing member 484 resists the starter 47 to move downward, so that the present invention is in a manual state; when the rotating plate 483 is in a horizontal state, the pressing member 484 releases the downward pressure on the starter 47, and the elastic member 481 drives the starter 47 to move upward, so that the present invention is in an electric state. The operator can switch between the manual state and the electric state by rotating the rotating plate 483, and the switching is convenient, fast, and efficient.

[0038] In this embodiment, the output shaft 46 of the rotary driver 41 is equipped with a cylindrical end cover 6, and the end cover 6 can rotate synchronously with the output shaft 46 of the rotary driver 41. The rotating plate 483 is rotatably connected to the top of the end cover 6, and the bottom of the end cover 6 is provided with an escape cavity 61 for rotating the down-pressing member 484 and accommodating the down-pressing member 484. The escape cavity 61 provides space for the rotation of the down-pressing member 484. When the down-pressing member 484 is in a horizontal state, the down-pressing member 484 is accommodated in the escape cavity 61, so that the down-pressing member 484 can rotate. The structure of the component 484 and the end cover 6 is compact, which reduces the volume of the present invention; the top of the end cover 6 is provided with a receiving cavity 62 for accommodating the rotating plate 483, the avoidance cavity 61 is communicated with the receiving cavity 62, the receiving cavity 62 and the rotating plate 483 are both semicircular, and when the rotating plate 483 is in a horizontal state, the rotating plate 483 is accommodated in the receiving cavity 62, and the rotating plate 483 is flush with the top surface of the end cover 6, so that the structure of the rotating plate 483 and the end cover 6 is compact, which reduces the volume of the present invention and makes the appearance of the present invention beautiful.

[0039] Specifically, the end cover 6, the starter 47 and the cam plate 42 are coaxially arranged to facilitate the synchronous rotation of the end cover 6, the cam plate 42 and the output shaft 46 of the rotary driver 41. The side wall of the accommodating cavity 62 is recessed with an avoidance groove 65 connected to the accommodating cavity 62. By adding the avoidance groove 65, the avoidance groove 65 provides more space for the operator's fingers, making it easier for the operator to rotate the horizontal rotating plate 483 to a vertical state.

[0040] Specifically, there are two pressing members 484, which are parallel and spaced apart. An opening groove 485 is recessed in the middle of the rotating plate 483, and the opening groove 485 is arc-shaped. The two pressing members 484 extend outward from the two side walls of the opening groove 485 respectively, and the opening groove 485 and the two pressing members 484 are arranged to form a U-shaped groove. A center cylinder 63 is protruded upward from the bottom wall of the accommodating cavity 62, and the center cylinder 63 is located at the center of the end cover 6. The rotating plate 483 is rotatably connected to the center cylinder 63 via a rotating shaft, and the center axis of the rotating shaft is perpendicular to the center axis of the center cylinder 63. The center cylinder 63 is located in the U-shaped groove, and the U-shaped groove provides a rotation space for the rotating plate 483 and the two pressing members 484. This structural design not only makes the structure between the handle 482 and the end cover 6 compact, but also facilitates the disassembly and maintenance of the handle 482 and the end cover 6, facilitates the handle 482 to drive the starter 47 to rise and fall, and facilitates the operator to switch between the manual state and the electric state, but also through the two pressing parts 484 respectively resisting different parts of the starter 47, the force on the starter 47 is evenly distributed, thereby improving the stability of the handle 482 driving the starter 47 to move downward.

[0041] Specifically, the output shaft 46 of the rotary driver 41 is a non-circular shaft, and the central cylinder 63 is provided with a first non-circular hole 64 that matches the non-circular shaft. After the non-circular shaft is inserted into the first non-circular hole 64, the end cover 6 is locked on the non-circular shaft by means of the bolt 7. The first non-circular hole 64 matches the non-circular shaft, thereby ensuring that the output shaft 46 of the rotary driver 41 and the end cover 6 rotate synchronously, thereby preventing the output shaft 46 of the rotary driver 41 and the end cover 6 from rotating relative to each other. Then, the end cover 6 is locked on the non-circular shaft by means of the bolt 7, thereby ensuring that the connection between the end cover 6 and the output shaft 46 of the rotary driver 41 is stable, thereby preventing the end cover 6 from being separated from the output shaft 46 of the rotary driver 41 during the rotation process.

[0042] Specifically, a second non-circular hole 424 cooperating with the non-circular shaft is provided in the middle of the cam disc 42, and the non-circular shaft passes through the second non-circular hole 424; the second non-circular hole 424 cooperates with the non-circular shaft to avoid relative rotation between the cam disc 42 and the output shaft 46 of the rotating driver 41, thereby ensuring that the cam disc 42 and the output shaft 46 of the rotating driver 41 rotate synchronously, thereby ensuring that the end cover 6, the cam disc 42 and the output shaft 46 of the rotating driver 41 can rotate synchronously.

[0043] Specifically, the starter 47 is provided with a through hole 471 for the output shaft 46 of the rotary driver 41 to pass through. The aperture of the through hole 471 is larger than the diameter of the output shaft 46 of the rotary driver 41 , so that the starter 47 will not rotate with the output shaft 46 of the rotary driver 41 .
