[0026] Example 1.

[0027] Preferably, the automatic lifting electric control platform vehicle 100 comprises:

[0028] The enabling switch 110 includes an ascending enabling switch 111 and a descending enabling switch 112. The ascending enabling switch 111 and the descending enabling switch 112 are electrically connected to the pump motor 130 through a wiring harness, respectively. The pump motor 130 is electrically connected to the electric control circuit 160.

[0029] The sensor 120 includes a high-position sensor 121 and a low-position sensor 122, and the high-position sensor 121 and the low-position sensor 122 are electrically connected to the electric control circuit 160 through a wiring harness;

[0030] The solenoid valve group 140 includes a plurality of solenoid valves, and the solenoid valve group 140 is electrically connected to the electric control circuit 160 through a wiring harness; wherein:

[0031] The electric control circuit 160 includes a current limiting resistor R1, the rising enabling switch 111 includes a switch body K1, and the falling enabling switch 112 includes a switch body K2. The switch bodies K1 and K2 are respectively connected to a power supply (not shown in the figure) through the current limiting resistor R1;

[0032] The electronic control circuit 160 also includes a current limiting resistor R2 and a microprocessor U1, the high-level sensor 121 includes a switch body K3, and the low-level sensor 122 includes a switch body K6. The switch body K3 and the switch body K6 are respectively connected to the microprocessor U1 through the current limiting resistor R2, each solenoid valve is respectively connected to the microprocessor U1, and the pump motor 130 is connected to the microprocessor U1; the sensor 120 and the enable switch 110 are used as input objects of the microprocessor U1, and the solenoid valve group 140 is used as an output object of the microprocessor U1, so as to realize the rising cycle and the falling cycle.

[0033] Among them, the rising enable switch 111 also includes a contact X1 and a contact X2, which are connected in parallel to each other and connected to the switch body K1 at the same time, so that when any contact of the rising enable switch 111 is activated (triggered), the switch body K1 can be turned on, thereby making the rising enable switch 111 effective, avoiding failure of the rising enable switch 111 due to poor contact.

[0034] Among them, the descent enable switch 112 also includes a contact X3 and a contact X4, which are connected in parallel to each other and connected to the switch body K2 at the same time, so that when any contact of the descent enable switch 112 is activated (triggered), the switch body K2 can be turned on, thereby making the descent enable switch 112 effective, avoiding failure of the descent enable switch 112 due to poor contact.

[0035] Among them, the high-level sensor 121 also includes relay K4 and relay K5, which are connected in parallel to each other and connected to the switch body K3 at the same time, so that when at least one relay of the high-level sensor 121 is working, the switch body K3 can be turned on, thereby allowing the high-level sensor 121 to output a high-level analog signal.

[0036] Among them, the low-level sensor 122 also includes relay K7 and relay K8, which are connected in parallel to each other and are simultaneously connected to the switch body K6, so that when at least one relay of the low-level sensor 122 is working, the switch body K6 can be turned on, thereby allowing the low-level sensor 122 to output a low-level analog signal.

[0037] Preferably, the solenoid valve group 140 includes a first solenoid valve 141, a second solenoid valve 142, a third solenoid valve 143 and a fourth solenoid valve 144, and each solenoid valve works simultaneously. If an individual solenoid valve fails, the solenoid valve group 140 as a whole can still effectively realize the ascent or descent of the platform.

[0038] The beneficial effects of the automatic lifting electric-controlled platform vehicle of this embodiment are described below.

[0039] During the production process, the automatic lifting electric control platform vehicle can be placed next to the assembly line or workbench to facilitate operators to take goods up and down, which helps to improve the work fatigue caused by frequent bending over to take goods.

[0040] The working principle of the automatic lifting electric-controlled platform vehicle of this embodiment is described below.

[0041] When the ascending enable switch 111 is activated and the uppermost cargo is removed, the high position sensor 121 detects no cargo, the low position sensor 122 detects the presence of cargo, the pump motor 130 starts working, and the platform rises. When it rises to the uppermost position, the high position sensor 121 detects the cargo again, and the pump motor 130 stops working. When the cargo is removed again, the pump motor 130 is started again, and the cycle continues. When the cargo at the bottom is also removed and the low position sensor 122 detects that there is no cargo, the limit structure 150 (upper position) is also activated, and the entire ascending cycle ends.

[0042] When the descending enable switch 112 is activated and the first layer of goods is placed, the high position sensor 121 detects the goods, the solenoid valve group 140 starts working, and the platform descends. When it descends to the low position, the low position sensor 122 detects the goods, and the solenoid valve group 140 stops working. When the goods are stacked again, the solenoid valve group 140 starts working again, and the cycle is repeated. When the last layer of goods is placed, the limit structure 150 (low position) is also activated at the same time, and the whole descending cycle ends.

[0043] Example 2.

[0044] Based on Example 1, Example 2 further includes the following technical solutions.

[0045] Optionally, the automatic lifting electric control platform vehicle 100 also includes a limit structure 150, which includes a limiter 151. The limiter 151 serves as an input object of the microprocessor U1. The limiter 151 is electrically connected to the microprocessor U1 to prevent the platform from lifting too high or too low, so that the platform can be lifted within a reasonable range.

[0046] It is worth mentioning that the technical features such as the specific selection of the microprocessor U1 involved in this utility model patent application should be regarded as the prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated.

[0047] For those skilled in the art, it is still possible to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
