[0026] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0027] See Figure 1 , Figure 1 The controller 100 is mainly a device that can automatically ignite and start the engine on agricultural machinery and equipment such as diesel engines or tractors. It effectively reduces the labor intensity increased by manually starting the engine by hand, and is more convenient, which is deeply loved by consumers. However, in the past, the controller 100 needed to draw power from the battery, and the battery had to be connected to the power supply terminal of the relay on the starter through two or more power supply lines. In this way, it is bound to increase the wiring connection work for people.
[0028] As Figures 1-3 shown, the power supply terminal of the controller 100 in the prior art is connected to the power supply terminal of the starter on the diesel engine or engine through the first power supply line A11 and the second power supply line B12. The starter is, for example, a relay on the diesel engine or engine. One end of the relay is connected to the first power supply line A11 and the second power supply line B12, and the other end is connected to the ignition motor. The ignition motor is controlled by the relay. The power supply terminal of the controller 100 is also connected to the power supply through another third power supply line A14 and a fourth power supply line B15. That is, at least four power supply lines are required in the prior art, resulting in a large number of connected wires, cumbersome connection and inconvenience in use.
[0029] To solve the above problems, the first embodiment of the present application discloses a controller 100 for starting a machine device. Please refer to Figure 4 , the controller 100 includes a controller body and a power supply terminal installed on the controller body, a power supply line C, a power supply line D connected to the power supply terminal, and a control line 13 connected to the controller body. The power supply terminal includes a first power supply interface and a second power supply interface. The controller 100 is electrically connected to the relay on the starter through the control line 13. The first power supply interface and the second power supply interface of the controller 100 are respectively electrically connected to the first power supply line A11 and the second power supply line B12 through the power supply line C16 and the power supply line D17. Specifically, one ends of the power supply line C16 and the power supply line D17 that are not connected to the power supply terminal of the controller 100 are both provided with wire docking heads A.
[0030] See Figures 2-4, the controller body further includes: a housing 10, a control chip 20, a circuit board 30, a first relay 40 located inside the housing 10, and a switch button 50 and an indicator light 60 installed on the surface of the housing 10. The circuit board 30 and the first relay 40 are both electrically connected to the control chip 20. The first power supply interface, the second power supply interface, the switch button 50, and the indicator light 60 are all connected to the circuit board 30.
[0031] It should be noted that the power supply lines C16 and D17 are components of the controller. One end of each of the power supply lines C16 and D17 is fixed to the power supply end of the power supply device, that is, they are respectively connected to the first power supply interface and the second power supply interface. Since the lengths of the power supply lines C16 and D17 are much shorter than those of the first power supply line A11 and the second power supply line B12, and the other ends of the power supply lines C16 and D17 have wire docking connectors A, through which they can be directly electrically connected to the first power supply line A11 and the second power supply line B12. Among them, one end of the first power supply line A11 and the second power supply line B12 are respectively connected to the positive and negative power interfaces of the power supply, and the other ends of the first power supply line A11 and the second power supply line B12 are electrically connected to the power supply end of the relay on the starter. The controller is directly electrically connected to the first power supply line A11 and the second power supply line B12 through the power supply lines C16 and D17, so that the power supply end of the controller 100 and the power supply end of the relay on the starter share the first power supply line A11 and the second power supply line B12, reducing the number of power supply wires required for connecting the power supply end of the controller 100 to the power supply and the power supply end of the relay on the starter in the prior art.
[0032] In addition, in order to be adapted to the power supply lines C16 and D17, another wire docking connector B adapted to the wire docking connector A is configured on the first power supply line A11 and the second power supply line B12. By docking the wire docking connector A with the wire docking connector B, the power supply line C16 is electrically connected to the first power supply line A11 and the power supply line D17 is electrically connected to the second power supply line B12. For convenient use, the installation position of the wire docking connector B can be selected as needed.
[0033] In this embodiment, after the power supply lines C16, D17, first power supply line A11, and second power supply line B12 are docked and connected, they are connected to the power supply end (first power supply interface, second power supply interface) of the controller 100 as a whole. Alternatively, after the power supply lines C16 and D17 are fixedly connected to the power supply end of the controller 100, they are connected to the first power supply line A11 and the second power supply line B12 as a whole and then electrically connected correspondingly.
[0034] By directly connecting the power cord of the controller to the first wire A and the second wire B, and the first wire A and the second wire B extend towards both ends, one end is directly plugged into the plug interface of the starting power supply or battery through a plug connector, and the other end is connected to the power supply terminal on the relay of the engine or diesel engine, effectively reducing the complexity of the controller installation.
[0035] The working principle of the circuit of this application: Press the switch button, the control chip 20 supplies power to the first relay 40, causing the first relay to close, and the start indicator light 60 lights up. The main control chip provides the closing time of the first relay 40 according to the set mode. When the set time arrives, the relay disconnects, and the power supply can stop supplying power.
[0036] Refer to Figures 5-6 , the second embodiment of this application discloses a controller 100 for starting a machine device. The difference between the second embodiment and the first embodiment is that the controller 100 has a first power supply line A11, a control line 13, a third power supply line A14, and a fourth power supply line B15. The first power supply line A11 is connected to the first power supply interface of the controller 100. The first power supply interface is a positive interface, and the second power supply interface is a negative interface. The housing 10 of the controller 100 is made of a metal material, the housing 10 is grounded, and the housing 10 forms a power-on circuit with the positive interface of the controller 100. Compared with the prior art, one second power supply wire B is saved, further reducing the complexity of wiring.
[0037] In this embodiment, both sides of the housing 10 have fixing ears 70, and bolts pass through the fixing ears 70 and are fixed on the machine device.
[0038] The power supply of this application is an emergency power supply, such as a battery, a stored power supply, etc., and the starter is the starter of the machine device that needs to be started.
[0039] In this embodiment, one end of the third power supply line A14 and the fourth power supply line B15 is plugged into the positive and negative interfaces of the power supply, and one end of the third power supply line A14 and the fourth power supply line B15 is made into a plug 90 and connected to the power supply.
