For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] See also Figures 1 to 4As shown, this embodiment provides an aerial work vehicle with an anti-collision system, including a chassis 105, a control box 107, an electronic control unit 109 and an operating handle 108; a front end distance measuring probe is provided at the front end of the chassis 105, and a rear end distance measuring probe is provided at the rear end of the chassis 105; the front end distance measuring probe and the rear end distance measuring probe are both connected to the control box 107, and the control box 107 is used to obtain the distance information detected by the front end distance measuring probe and the rear end distance measuring probe, wherein the distance information detected by the front end distance measuring probe is X1, and the distance information detected by the rear end distance measuring probe is X2; the electronic control unit 109 is connected to the control box 107, and is used to compare the distance information obtained by the control box 107 with the set distance information, and to control the walking of the chassis 105. The speed is controlled; the set distance information includes a safety distance S1 and a warning distance S2, when X1>S1, the chassis 105 moves forward normally, when S1≥X1>S2 or S1≥X2>S2, the chassis 105 moves slowly, when X1≤S2, the chassis 105 stops moving or moves backward; when X2>S1, the chassis 105 moves backward normally, when X2≤S2, the chassis 105 stops moving or moves forward; the operating handle 108 is connected to the electronic control unit 109, for issuing a moving, stopping or turning instruction of the chassis 105 to the electronic control unit 109, and the operating handle 108 can force the chassis 105 to move forward when X1≤S2, and force the chassis 105 to move backward when X2≤S2.

[0030] Based on this structure, the aerial work vehicle with an anti-collision system provided in this embodiment has a more complete anti-collision system, which can control the body chassis 105 to run normally, automatically slow down or stop according to the comparison result of the detected distance information and the set distance information, and can use the operating handle 108 to force the body chassis 105 to move forward or backward according to the actual situation, thereby reducing the possibility of misjudgment as stopping. When the aerial work vehicle moves forward, the control box 107 is used to obtain the distance information X1 detected by the front-end ranging probe. The electronic control unit 109 is connected to the control box 107, and is used to compare the distance information X1 obtained by the control box 107 with the safety distance S1 and the warning distance S2, and control the walking speed of the vehicle chassis 105. When X1>S1, the vehicle chassis 105 moves forward normally, when S1≥X1>S2, the vehicle chassis 105 moves forward slowly, and when X1≤S2, the vehicle chassis 105 stops moving or moves backward; the operating handle 108 is connected to the electronic control unit 109, and when the actual situation is that it does not need to stop, the operating handle 108 forces the vehicle chassis 105 to move forward. When the aerial work vehicle moves backward, the control box 107 is used to obtain the distance information X2 detected by the rear end ranging probe, and the electronic control unit 109 is used to compare the distance information X2 obtained by the control box 107 with the safety distance S1 and the warning distance S2, and control the walking speed of the vehicle chassis 105 and the buzzer 110 respectively. When X2>S1, the vehicle chassis 105 moves backward normally, when S1≥X2>S2, the vehicle chassis 105 moves backward slowly, and when X2≤S2, the vehicle chassis 105 stops moving or moves forward; when the actual situation is that there is no need to stop, the operating handle 108 forces the vehicle chassis 105 to move backward.

[0031] Preferably, the priority of the signal sent by the operating handle 108 is greater than the signal sent by the control box 107. This can further reduce the possibility of misjudging the stop.

[0032] Further, in certain optional embodiments, the aerial work vehicle with an anti-collision system also includes a buzzer 110. When X1>S1, the chassis 105 moves forward normally, and at this time, the buzzer 110 does not sound. When S1≥X1>S2, the chassis 105 moves forward slowly, and when S1≥X2>S2, the chassis 105 moves backward slowly, the buzzer 110 sounds to serve as a reminder. When X1≤S2, the chassis 105 stops moving or moves backward, the buzzer 110 continues to sound. At this time, the buzzer 110 may be different from the previous frequency, and emit a higher frequency or louder sound to prompt the operator to use the operating handle 108 to force the chassis 105 to move forward, reducing the possibility of misjudging it as a stop. When X2≤S2, the vehicle chassis 105 stops moving or moves forward, and the buzzer 110 continues to sound. At this time, the buzzer 110 may emit a higher frequency or a louder sound, which is different from the previous frequency, to prompt the operator to use the operating handle 108 to force the vehicle chassis 105 to retreat, thereby reducing the possibility of misjudging it as a stop.

[0033] Further, in some optional embodiments, the buzzer 110 includes a chassis buzzer and a PCU buzzer, the chassis buzzer is arranged on the vehicle body chassis 105 , and the PCU buzzer is arranged on the operating handle 108 .

[0034] When the lifting platform 106 of the aerial work vehicle is raised, the operator on the lifting platform 106 is far away from the vehicle chassis 105. If only the chassis buzzer is set on the vehicle chassis 105, the operator may not hear the alarm sound. Since the operating handle 108 is in the hands of the operator, or the operating handle 108 is raised and lowered with the operator on the lifting platform 106, the PCU buzzer is set on the operating handle 108 to ensure that the operator can clearly hear the alarm sound so as to quickly take corresponding defensive measures.

[0035] Furthermore, in some optional embodiments, the operating handle 108 is provided with a control panel for inputting set distance parameters.

[0036] The control panel is provided with operation buttons, operating levers, alarms, and displays. The operator can operate the aerial work vehicle on the operating handle 108. The operating handle 108 is connected to the ECU by a wiring harness for data transmission and data exchange. The working state of the aerial work vehicle can be transmitted to the operating handle 108 by the electronic control unit 109, and displayed on the display of the operating handle 108 and the response of the alarm can be realized.

[0037] In this embodiment, the operating handle 108 is a PCU handle.

[0038] Among them, PCU can be a process control unit.

[0039] Further, in certain optional embodiments, the front-end ranging probe includes a first ranging probe 101 and a second ranging probe 102, the first ranging probe 101 is located at the left side of the front end of the vehicle body chassis 105, and the second ranging probe 102 is located at the right side of the front end of the vehicle body chassis 105; the rear-end ranging probe includes a third ranging probe 103 and a fourth ranging probe 104, the third ranging probe 103 is located at the left side of the rear end of the vehicle body chassis 105, and the fourth ranging probe 104 is located at the right side of the rear end of the vehicle body chassis 105.

[0040] In this embodiment, the detection ranges of the first ranging probe 101 and the second ranging probe 102 can be superimposed to increase the detection range of a single ranging probe and enhance the detection sensitivity. The detection ranges of the third ranging probe 103 and the fourth ranging probe 104 can also be superimposed to increase the detection range of a single ranging probe and enhance the detection sensitivity.

[0041] Optionally, the overall detection range of the front-end ranging probe and the overall detection angle range α of the rear-end ranging probe may both reach or even exceed 64°.

[0042] Further, in some optional implementation schemes, the first ranging probe 101, the second ranging probe 102, the third ranging probe 103 and the fourth ranging probe 104 are all detection radars.

[0043] It should be noted that the detection radar is a prior art and its structure will not be described in detail.

[0044] Further, in certain optional implementation schemes, a fifth ranging probe and a sixth ranging probe are provided on the left side of the vehicle body chassis 105, and a seventh ranging probe and an eighth ranging probe are provided on the right side of the vehicle body chassis 105. The fifth ranging probe, the sixth ranging probe, the seventh ranging probe and the eighth ranging probe are all connected to the control box 107, and the control box 107 is used to obtain the distance information detected by the fifth ranging probe, the sixth ranging probe, the seventh ranging probe and the eighth ranging probe.

[0045] In this embodiment, the fifth ranging probe, the sixth ranging probe, the seventh ranging probe and the eighth ranging probe are all detection radars.

[0046] Since the four detection radars are arranged on the left and right sides of the front and rear ends, there are detection blind spots. When turning at a large angle, the blind spots cannot be detected, which is prone to collision. Therefore, two detection radars are arranged on the left and right sides of the vehicle chassis 105, respectively, to achieve obstacle detection and collision warning when turning at a large angle.

[0047] Further, in some optional embodiments, the fifth ranging probe and the sixth ranging probe are respectively located at two ends of the left side of the vehicle body chassis 105 , and the seventh ranging probe and the eighth ranging probe are respectively located at two ends of the right side of the vehicle body chassis 105 .

[0048] The detection ranges of the fifth and sixth ranging probes can also be superimposed to increase the detection range of a single ranging probe and enhance the detection sensitivity. Similarly, the detection ranges of the seventh and eighth ranging probes can also be superimposed to increase the detection range of a single ranging probe and enhance the detection sensitivity.

[0049] Furthermore, in certain optional embodiments, the aerial work vehicle with an anti-collision system further includes a warning light (not shown), which is connected to the electronic control unit 109 .

[0050] Further, in certain optional implementation schemes, when S1 ≥ X > S2, when X1 ≤ S2, and when X2 ≤ S2, the warning light, the chassis buzzer, and the PCU buzzer are all activated.

[0051] Furthermore, in certain optional embodiments, the aerial work vehicle with the anti-collision system further includes a main valve 113 and a motor controller 111 , and both the main valve 113 and the motor controller 111 are connected to the electronic control unit 109 .

[0052] The main valve 113 and the motor controller 111 are directly controlled by the electronic control unit 109. The aerial work vehicle with an anti-collision system provided in this embodiment also includes a motor and a motor pump 112. The main valve 113 is used to switch or adjust the hydraulic circuit 114. The motor controller 111 is used to control the speed of the motor. The motor pump 112 is connected to the motor in a transmission manner, and the flow of the motor pump 112 is affected and adjusted by the motor speed. The flow of the motor pump 112 can be controlled by controlling the motor speed. The walking mode of the aerial work vehicle is driven by a hydraulic motor, and the walking speed is controlled by the speed of the hydraulic motor. The speed of the hydraulic motor is controlled by the flow of the motor pump 112.

[0053] In this embodiment, the electronic control unit is an ECU. The control box 107 may be an existing MCU (micro control unit).

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
