Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of camping vehicles, and particularly to a power control device and method for a camping vehicle expansion mechanism. Background Art

[0002] A camping vehicle is a special vehicle for roads, which is not only a transportation and passenger equipment, but also can be used as a mobile barracks for sleeping and resting. Therefore, a camping bus needs to be configured and designed with cabins that can be widened on both sides of the vehicle, and the technical route of the electric control expansion mechanism is a good solution for camping buses. Since camping requires long-term power consumption, and the camping site may be far from the charging pile and inconvenient to charge, it is necessary to reserve sufficient remaining power. Therefore, it is particularly important to provide an energy-saving solution to relieve the user's power consumption anxiety during camping.

[0003] However, most of the energy-saving solutions proposed in the related art are for energy saving when the vehicle is in a driving state or a parking state. When the camping vehicle is in a camping mode, the power supply for the expansion mechanism is often always on, which is power-consuming and prone to abnormal out-of-control conditions. Summary of the Invention

[0004] In view of the above problems, the embodiments of the present invention provide a power control device and method for a camping vehicle expansion mechanism, which overcome or at least partially solve the above problems.

[0005] According to one aspect of the embodiments of the present invention, there is provided a power control device for a camping vehicle expansion mechanism, including: a power supply module, a main power contactor connected to the power supply module, an expansion mechanism control box connected to the main power contactor, and a controller, the controller being communicatively connected to the expansion mechanism control box and the main power contactor; the controller outputs a power-on control signal to control the main power contactor to close; and after receiving a feedback signal that the main power contactor is closed, outputs a startup control signal to the expansion mechanism control box to control the expansion mechanism control box to start working.

[0006] Optionally, the main power contactor includes a detection feedback terminal unit, a coil, and a high-power contactor.

The negative terminal of the coil of the main power contactor is grounded together with the negative terminal of the expansion mechanism control box. The positive terminal of the coil of the main power contactor is connected to the controller for receiving the power-on control signal output by the controller. When the coil is energized, electromagnetic suction is generated to connect the input contact and the output contact of the main power contactor, and power is supplied to the expansion mechanism control box. The detection terminal of the main power contactor is connected to the controller for detecting whether the power-on control signal of the main power contactor is valid and whether the contactor contacts are closed.

[0014] Optionally, the power supply control method further includes: when the status feedback signal of the main power contactor is detected to be abnormal, the controller stops outputting the power-on control signal to the expansion mechanism control box to pause the operation of the expansion mechanism control box; when it is detected that the main power contactor abnormally disconnects the power output, a fault code is fed back to the instrument to prompt the fault information.

[0016] The above description is only an overview of the technical solution of the embodiment of the present invention. In order to be able to understand the technical means of the embodiment of the present invention more clearly, it can be implemented according to the content of the specification. And in order to make the above and other purposes, features and advantages of the embodiment of the present invention more obvious and understandable, the following specifically describes the embodiments of the present invention.

The drawings are only for the purpose of showing the preferred embodiments and are not considered to be a limitation of the present invention. And throughout the drawings, the same reference numerals are used to represent the same components. In the drawings:

[0020] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be fully conveyed to those skilled in the art.

[0021] Figure 1 The structural schematic diagram of the power control device of the camping vehicle expansion mechanism provided by the embodiment of the present invention is shown. As Figure 1 shown, the power control device of the camping vehicle expansion mechanism includes: a power supply module 1, a main power contactor 2 connected to the power supply module 1, an expansion mechanism control box 3 connected to the main power contactor 2, and a controller 4, and the controller 4 is communicatively connected to the expansion mechanism control box 3 and the main power contactor 2; the controller 4 outputs a power-on control signal to control the main power contactor 2 to close; and after receiving the feedback signal that the main power contactor 2 is closed, it outputs a startup control signal to the expansion mechanism control box 3 to control the expansion mechanism control box 3 to start working.

[0022] In the embodiment of the present invention, the main power contactor 2 includes a detection feedback terminal unit, a coil, and a high-power contactor K1. The contact input end of the main power contactor 2 is connected to the power supply module, and the contact output end of the main power contactor 2 is connected to the power supply end of the expansion mechanism control box. The contact input end of the main power contactor 2 is the contact input end of the high-power contactor K1, and the contact output end of the main power contactor 2 is the contact output end of the high-power contactor K1. The negative terminal of the coil of the main power contactor 2 is grounded GND together with the negative terminal of the expansion mechanism control box 3, and the positive terminal of the coil of the main power contactor 2 is connected to the controller 4 for receiving the power-on control signal C1 output by the controller 4. When the coil is energized, electromagnetic suction is generated to connect the input contact and the output contact of the main power contactor 2 to power on the expansion mechanism control box 3; the detection end of the main power contactor 2 is connected to the controller 4 for detecting whether the power-on control signal of the main power contactor 2 is valid and whether the contactor contacts are closed.

[0023] The main power contactor 2 further includes a diode D. The cathode of the diode D is connected to the positive terminal of the coil of the main power contactor 2, and the anode of the diode D is connected to the negative terminal of the coil of the main power contactor 2 to achieve the function of freewheeling and peak elimination.

[0024] The power control device further includes a circuit breaker F. One end of the circuit breaker F is connected to the power supply module 1, and the other end is connected to the contact input end of the main power contactor 2.

[0025] The power control device further includes an emergency power switch K2. The input end of the emergency power switch K2 is connected to the circuit breaker F, and the output end is connected to the power supply end of the expansion mechanism control box 3. The emergency power switch is a manual switch. Press the operating handle of the emergency power switch K2 to disconnect (when the operating panel of the expansion mechanism control box is not repaired and opened, the emergency power switch is physically locked in the off state). Open the operating panel of the expansion mechanism control box 3, and then rotate the lifting operating handle clockwise to connect. In this way, if it is detected that the main power contactor abnormally disconnects the power output, the expansion mechanism control box can be manually powered by the emergency power switch K2 to meet the requirements of maintenance or emergency situations.

[0026] The power supply module 1 includes a battery unit 10 and a power distribution box 11 connected in series with the battery unit 11. The power distribution box 11 is used to distribute the power provided by the battery unit 10.

[0027] The controller 4 is a remote controller and is wirelessly communicatively connected to the main power contactor and the expansion mechanism control box. That is, the controller 4 can wirelessly communicate with the main power contactor and the expansion mechanism control box, and can also be directly connected to the main power contactor and the expansion mechanism control box to transmit information therebetween.

[0028] In the embodiment of the present invention, when the camping vehicle is in the camping mode, the controller 4 sends a power-on control signal to the main power contactor 2. After receiving the power-on control signal, the main power contactor 2 closes the main power contactor 2 and feeds back the power state of the main power contactor 2 to the controller 4. The controller 4 outputs a power-on control signal to the expansion mechanism control box 3 according to the received feedback signal. After receiving the power-on control signal, the expansion mechanism control box can perform the retraction or extension operation on the expansion mechanism. If the controller 4 does not receive the feedback signal of the main power contactor, it stops sending the power-on control signal to the expansion mechanism control box, and then stops sending the power-on control signal to the main power contactor. In this way, the power on and off of the expansion mechanism can be controlled more reasonably, effectively preventing abnormal out-of-control situations.

[0029] Based on the same concept, the embodiment of the present invention further provides a power control method for the expansion mechanism of a camping vehicle, which is applied to the power control device for the expansion mechanism of the camping vehicle described above. As Figure 2 shown, the power control method for the expansion mechanism of the camping vehicle includes:

[0030] Step S11: The controller outputs a power-on control signal to the main power contactor.

[0031] When the camping vehicle is in the camping mode, the controller outputs a power-on control signal to the main power contactor. Otherwise, the controller stops outputting the power-on control signal to the main power contactor. The power-on control signal is valid at high level.

[0032] Step S12: The main power contactor performs a closing operation according to the received power-on control signal, detects the controlled working condition of the main power contactor, and feeds back a status signal indicating that the main contacts are normally closed.

[0033] The main power contactor performs a closing operation according to the received power-on control signal, detects the controlled working condition of the main power contactor, and feeds back a status signal indicating that the main contacts are normally closed. This status signal is active high and is used to indicate the controlled status fed back after the main power contactor is normally powered. If the controller does not receive the status signal indicating that the main contacts of the main power contactor are normally closed, it stops outputting the power-on control signal to the main power contactor, thereby controlling the main power contactor to stop supplying power to the expansion mechanism control box, so as to save electricity and avoid abnormal out-of-control situations caused by incorrect power supply, etc.

[0034] Step S13: The controller outputs a startup control signal to the expansion mechanism control box according to the feedback signal to control the expansion mechanism control box to start working.

[0035] If the status signal indicates that the main power contactor is normally closed, the controller outputs a startup control signal to the expansion mechanism control box. After receiving the startup control signal, the expansion mechanism control box can control the expansion mechanism to extend or retract as needed.

[0036] In the embodiment of the present invention, if it is detected that the status feedback signal of the main power contactor is abnormal, the controller stops outputting the startup control signal to the expansion mechanism control box to pause the operation of the expansion mechanism control box. If it is detected that the main power contactor abnormally disconnects the power output, a fault code is fed back to the instrument to prompt the fault information. At this time, if it is confirmed that manual control of the expansion mechanism is required, the operation panel of the expansion mechanism control box needs to be opened, and the emergency power switch handle is closed to provide emergency power supply requirements for the expansion mechanism control box.
