[0032] This embodiment provides a circuit system for an aerial work platform vehicle, as shown in Figure 1. It includes a control circuit 100, a power supply 200, and a switch 300 connected in series. The power supply 200 supplies power to the control circuit 100, and the switch 300 turns the control circuit 100 on and off. The control circuit 100 includes multiple control branches connected in parallel, each branch controlling different components of the aerial work platform vehicle to achieve the function of carrying personnel at height. Specifically, the control circuit 100 includes:

[0033] The first control branch 110 includes a first rotary switch 111, a second rotary switch 112, a first solenoid valve 113, and a second solenoid valve 114.

The first rotary switch 111 is connected to both the first solenoid valve 113 and the second solenoid valve 114, and the second rotary switch 112 is connected to both the first solenoid valve 113 and the second solenoid valve 114. For example, the first rotary switch 111 has three positions: left-hand, center, and right-hand. The left-hand position is connected to the first solenoid valve 113 and is used to control the raising of the boom of the aerial work platform's robotic arm. The right-hand position is connected to the second solenoid valve 114 and is used to control the lowering of the boom. The center position is not connected to the circuit system and serves to disconnect the circuit. All the rotary switches described below adopt the same structure and connection method as the first rotary switch 111. The second rotary switch 121, when turned counterclockwise, connects to the first solenoid valve 113 to control the raising of the boom in the aerial work platform's robotic arm; when turned clockwise, it connects to the second solenoid valve 114 to control the lowering of the boom. The first rotary switch 111 and the second rotary switch 112 can independently control the opening and closing of the first solenoid valve 113 and the second solenoid valve 114, thereby controlling the raising and lowering of the boom in the aerial work platform's robotic arm via the hydraulic system. This allows for control of the boom from two different positions, increasing the convenience of aerial work platform control.

[0034] The second control branch 120 includes a third rotary switch 121, a fourth rotary switch 122, a third solenoid valve 123, and a fourth solenoid valve 124.

The third rotary switch 121 is connected to both the third solenoid valve 123 and the fourth solenoid valve 124, and the fourth rotary switch 122 is also connected to both the third solenoid valve 123 and the fourth solenoid valve 124. The third rotary switch 121, when turned counter-clockwise, connects to the third solenoid valve 123 to control the raising of the two arms of the aerial work platform's robotic arm; when turned clockwise, it connects to the fourth solenoid valve 124 to control the lowering of the two arms. Similarly, the fourth rotary switch 122, when turned counter-clockwise, connects to the third solenoid valve 123 to control the raising of the two arms of the aerial work platform's robotic arm; when turned clockwise, it connects to the fourth solenoid valve 124 to control the lowering of the two arms. The third rotary switch 121 and the fourth rotary switch 122 can independently control the opening and closing of the third solenoid valve 123 and the fourth solenoid valve 124, and then control the lifting and lowering of the two arms in the aerial work platform's robotic arm through the hydraulic system, thereby realizing the control of the two arms in two different positions and increasing the convenience of aerial work platform control.

[0035] The third control branch 130 includes a fifth rotary switch 131, a sixth rotary switch 132, a fifth solenoid valve 133, and a sixth solenoid valve 134. The fifth rotary switch 131 and the sixth rotary switch 132 are connected in parallel. The fifth rotary switch 131 is connected to both the fifth solenoid valve 133 and the sixth solenoid valve 134, and the sixth rotary switch 132 is also connected to both the fifth solenoid valve 133 and the sixth solenoid valve 134. The fifth rotary switch 131, when turned counter-clockwise, connects to the fifth solenoid valve 133 to control the raising of the boom of the aerial work platform. When turned clockwise, it connects to the sixth solenoid valve 134 to control the lowering of the boom. Similarly, the sixth rotary switch 132, when turned counter-clockwise, connects to the fifth solenoid valve 133 to control the raising of the boom. When turned clockwise, it connects to the sixth solenoid valve 134 to control the lowering of the boom. The fifth rotary switch 131 and the sixth rotary switch 132 can independently control the opening and closing of the fifth solenoid valve 133 and the sixth solenoid valve 134, respectively, and then control the lifting and lowering of the boom in the aerial work platform's robotic arm through the hydraulic system, thereby realizing the control of the boom in two different positions and increasing the convenience of aerial work platform control.

[0036] The fourth control branch 140 includes a seventh rotary switch 141, an eighth rotary switch 142, a seventh solenoid valve 143, and an eighth solenoid valve 144. The seventh rotary switch 141 and the eighth rotary switch 142 are connected in parallel. The seventh rotary switch 141 is connected to both the seventh solenoid valve 143 and the eighth solenoid valve 144, and the eighth rotary switch 142 is connected to both the seventh solenoid valve 143 and the eighth solenoid valve 144. The seventh rotary switch 141, when turned left, connects to the seventh solenoid valve 143 to control the turntable of the aerial work platform to rotate to the left, and when turned right, connects to the eighth solenoid valve 144 to control the turntable of the aerial work platform to rotate to the right. Similarly, the eighth rotary switch 142, when turned left, connects to the seventh solenoid valve 143 to control the turntable of the aerial work platform to rotate to the left, and when turned right, connects to the eighth solenoid valve 144 to control the turntable of the aerial work platform to rotate to the right. The seventh rotary switch 141 and the eighth rotary switch 142 can independently control the opening and closing of the seventh solenoid valve 143 and the eighth solenoid valve 144, respectively, and then control the turntable of the aerial work platform to rotate left and right through the hydraulic system, thereby realizing the control of the turntable in two different positions and increasing the convenience of controlling the aerial work platform.

[0037] In practical applications, adjusting the first rotary switch 111 and the second rotary switch 112 controls the lifting and lowering of the main arm of the robotic arm; adjusting the third rotary switch 121 and the fourth rotary switch 122 controls the lifting and lowering of the second arm of the robotic arm; adjusting the fifth rotary switch 131 and the sixth rotary switch 132 controls the lifting and lowering of the forearm of the robotic arm; and adjusting the seventh rotary switch 141 and the eighth rotary switch 142 controls the rotation of the turntable. Through the overall coordination of the main arm, second arm, forearm, and turntable, the work bucket and the worker are transported to the designated position to complete the high-altitude operation.

[0038] Optionally, the control circuit 100 further includes a fifth control branch 150, which includes a ninth rotary switch 151 and a lighting device 152, connected in series. The left-hand or right-hand position of the ninth rotary switch 151 connects to the lighting device 152, while the middle position does not connect to the circuit system, effectively disconnecting it. When the ninth rotary switch 151 is turned left or right according to the connection method, the lighting device 152 illuminates, providing illumination for the workers.

[0039] Optionally, the control circuit 100 further includes a sixth control branch 160, which includes a tenth rotary switch 161, a ninth solenoid valve 162, and a tenth solenoid valve 163. The tenth rotary switch 161 is connected to the ninth solenoid valve 162 and the tenth solenoid valve 163 respectively. The left-hand position of the tenth rotary switch 161 is connected to the ninth solenoid valve 163 to control the lifting of the aerial work platform's hook, and the right-hand position is connected to the tenth solenoid valve 164 to control the lowering of the aerial work platform's hook. The left-hand and right-hand rotations of the tenth rotary switch 161 control the lifting and lowering of the hook respectively to lift large items required for the operation.

[0040] Preferably, the first solenoid valve 113, the second solenoid valve 114, the third solenoid valve 123, the fourth solenoid valve 124, the fifth solenoid valve 133, the sixth solenoid valve 134, the seventh solenoid valve 143, the eighth solenoid valve 144, the ninth solenoid valve 163, and the tenth solenoid valve 164 are all connected in parallel to a set of series-connected resistors 500 and diodes 600. Since the solenoid valves contain coils, the coils will generate back electromotive force when de-energized, which may damage the connecting components. The series-connected diodes 600 can provide a circuit, allowing the energy stored in the coils to be released, thus playing a freewheeling role and protecting other components in the circuit. Since the diodes 600 have unidirectional conductivity, when the reverse voltage exceeds their rated value, the diodes 600 will break down, causing component damage. The series-connected resistors 500 can limit the current and protect the diodes 600 from damage.

[0041] Specifically, switch 300 includes an emergency stop switch 310 and an ignition switch 320. The emergency stop switch 310 and the ignition switch 320 are connected in series. The emergency stop switch 310 is a normally closed switch, and the ignition switch 320 is a normally open switch. The emergency stop switch 320 is used to disconnect the control circuit 100 and the power supply 200 in case of an emergency. The ignition switch 320 is used to start and stop the aerial work, and to connect and disconnect the control circuit 100 and the power supply 200. By setting the emergency stop switch 310 and the ignition switch 320, the start, stop and emergency stop of the aerial work vehicle control circuit 100 can be realized.

[0042] Furthermore, the emergency stop switch 310 includes a first emergency stop switch 311 and a second emergency stop switch 312, which are connected in series. Both the first emergency stop switch 311 and the second emergency stop switch 312 can disconnect the control circuit 100 from the power supply 200, thereby enabling emergency stopping of the control circuit 100 at two different locations, increasing the convenience and safety of controlling the aerial work platform.

[0043] Furthermore, the ignition switch 320 includes a first ignition switch 321 and a second ignition switch 322, which are connected in parallel. Both the first ignition switch 321 and the second ignition switch 322 can independently turn on and off the connection between the control circuit 100 and the power supply 200, thereby enabling the start and stop of the control circuit 100 in two different positions, increasing the convenience of controlling the aerial work platform.

[0044] Optionally, the power supply 200 is a DC power supply. Aerial work vehicles using DC power supplies have a relatively simple structure, require less maintenance, and are conducive to reducing operating costs and improving work efficiency. At the same time, DC power supplies generate less noise during operation and are more adaptable to complex environments.

[0045] This embodiment also provides a dual-position control panel for an aerial work platform. The dual-position control panel 400 includes a first control panel 410 and a first control lever 411. The first control panel 410 and the first control lever 411 are mounted on the work platform of the aerial work platform. The first control panel 410 is equipped with a first rotary switch 111, a third rotary switch 123, a fifth rotary switch 131, a seventh rotary switch 141, a ninth rotary switch 151, a first ignition switch 321, and a first emergency stop switch 311. The first control panel 410 and corresponding switches on the work platform can control the lifting and lowering of the boom, second arm, and forearm of the aerial work platform, the rotation of the turntable, the switching of lighting devices, the start / stop of control circuits, and emergency stop. When controlling the corresponding knobs for lifting and lowering the boom, second arm, and forearm, and rotating the turntable, the first control lever 411 must be pulled simultaneously to complete the corresponding control. This design avoids accidental activation and reduces operational safety risks.

[0046] Furthermore, the dual-position control panel 400 also includes a second control panel 420 and a second control lever 421. The second control panel 420 and the second control lever 421 are mounted on the turntable of the aerial work platform. The second control panel 420 is equipped with a second rotary switch 112, a fourth rotary switch 122, a sixth rotary switch 132, an eighth rotary switch 142, a tenth rotary switch 161, a second ignition switch 322, and a second emergency stop switch 312. The second control panel 420 and corresponding switches on the turntable allow control of the lifting and lowering of the boom, jib, and forearm of the aerial work platform, the rotation of the turntable, the lifting and lowering of the hook, the start / stop of the control circuit, and the emergency stop. When controlling the corresponding knobs for lifting and lowering the boom, jib, and forearm, rotating the turntable, and lifting and lowering the hook, the second control lever 411 must be pulled simultaneously to complete the corresponding control. This design avoids accidental activation and reduces operational safety risks.

[0047] In practical applications, dual-position control of the aerial work platform control circuit 100 is achieved through the first control panel 410 set on the work bucket and the second control panel 420 set on the turntable. Workers can flexibly choose which control panel to use according to the actual working needs of the aerial work platform, making it more convenient and faster to complete aerial work.
