Description

Technical Field

[0001] The present application relates to a central control box for a motorhome, and belongs to the technical field of lock accessories. Background Art

[0002] With the improvement of living needs, RVs are gradually promoted and enter people's daily lives. Based on different needs, RVs usually include multiple areas, such as the driving area, RV area, etc. Correspondingly, RVs are also equipped with locks for multiple parts such as the cab, hatch locks, and RV doors. The configuration of these locks improves the different functional needs of RVs, but due to the independence of various parts of RVs, there are many types of locks on RVs. Different types of locks are opened and locked separately, and it is impossible to achieve linkage one-button start, which seriously affects the convenience and controllability of operation. Utility Model Content

[0003] In view of this, the present application provides a central control box for an RV, which realizes the linkage of multiple locks of the RV to enable one-button start, greatly facilitating operation.

[0004] Specifically, the present application is implemented through the following scheme:

[0005] The RV central control box is matched with a remote control key. The central control box includes a shell and a circuit board. The circuit board is located inside the shell. The circuit board is provided with a central control pulse voltage 2P socket, a vehicle power input 2P socket, a 6V fixed power output 2P socket, a 12V alternating power output 2P socket, a remote control pairing key and a door lock pairing key.

[0006] In the above device, the central control pulse voltage 2P socket is mainly used to power the cab, the vehicle power input 2P socket is usually fixed 12V, which powers the central control box; the 6V fixed power output 2P socket is mainly used for wired power supply for the hatch lock, and the 12V alternating power output 2P socket is used to realize opening and closing through positive and negative exchange, and the remote control key matched with the central control box is paired with the remote control pairing key and the door lock pairing key. With the help of different pairings, the device can realize multi-level control and complete full coverage control for only a certain component or all components.

[0007] The central control box is also equipped with a battery to replace the vehicle power input 2P socket, that is, the power supply of the central control box can be powered by the vehicle power input 2P socket or by the battery. More preferably, the battery is installed in the shell through the positive electrode connecting piece, the negative electrode connecting piece and the positive and negative electrode connecting pieces, and the shell is equipped with a box cover, and the battery is installed between the box cover and the shell. At least one set of gaskets is arranged between the box cover and the battery.

[0008] The circuit board is fixed on the housing through a bottom cover.

[0009] The circuit board is provided with an indicator light. When the power is turned on, the buzzer sounds once and the indicator light flashes once; when the opening command is given, the buzzer sounds twice and the indicator light flashes twice; when the closing command is given, the buzzer sounds three times and the indicator light flashes three times; in the low power state (battery voltage is lower than 5V), 6 seconds after the opening command or closing command is completed, the red indicator light flashes 12 times and then goes out, and the buzzer sounds 12 times.

[0010] The central control box includes three levels of control: the first level control is controlled by the central control in the cab, and controls the opening and closing of the cab door lock, the RV main door lock and the hatch door lock, and the 12V power box cabinet lock at the same time; the second level control is controlled by the RV door lock remote control, and controls the opening and closing of the RV main door lock and the hatch door lock, and the 12V power box cabinet lock at the same time; the third level control is independent remote control, which only controls the opening and closing of the hatch door lock or the 12V power box cabinet lock. More preferably, the first-level control controls the RV door lock switch by outputting a 12V alternating voltage signal through a wired connection to the 12V alternating power output 2P socket to control the PCB board to emit a radio frequency signal, and at the same time, the PCB board controls the hatch lock and the opening or closing of the 12V power box cabinet lock by turning the power on and off, that is, the car central control device simultaneously controls the opening or closing of the RV lock, cab door lock, hatch door lock and 12V power box cabinet lock; the second-level control and the third-level control are realized through the group keys of the RV main door lock remote control, and the RV door lock remote control is used to simultaneously control the opening or closing of the RV main door lock, hatch door lock and 12V power box cabinet lock.

[0011] The control logic of the above levels is as follows:

[0012] Primary control logic: The cab central control sends pulse electricity to the PCB control board and the cab door lock, and the cab door lock is opened or closed (open or closed is controlled by positive or negative voltage). At the same time, the PCB sends out an open or closed radio frequency signal, and the RV main door lock receives the open or closed signal to open or close the lock. At the same time, the PCB controls the power supply to power on or off the hatch lock or the 12V power cabinet lock. The hatch lock and cabinet lock are switched on and off by turning the power on and off.

[0013] Secondary control logic: The RV main door lock remotely controls the PCB controller. The PCB sends out an open or closed radio frequency signal. The RV main door lock receives the open or closed signal and performs an unlocking or locking action. At the same time, the PCB controls the power supply to power on or off the hatch lock and the 12V power box cabinet lock. The hatch lock and the 12V power box cabinet lock are turned on and off by turning the power on and off.

[0014] Three-level control logic: The RV main door lock remote control PCB controller only controls the hatch lock or 12V power box cabinet lock switch.

[0015] In the above scheme,

[0016] Control priority: cab central control > RV lock remote control (if there is a cab central control, there is no need for an additional remote control, use the remote control or central control switch that comes with the cab central control).

[0017] Control connection door locks: cab door lock - RV main door lock - hatch door lock - 12V power box cabinet lock;

[0018] The connection mode between the lock and the controller: central door lock (cab door lock) wired connection - RV main door lock wireless (radio frequency signal) connection - hatch lock wired (fixed power on / off) connection / 12V cabinet lock wired (switching power on / off) connection;

[0019] The coding includes three levels:

[0020] Primary control PCB board code matching: PCB board and RV main door lock code matching;

[0021] Secondary control PCB board pairing: After the RV lock remote control is paired with the PCB board, use the switch group of the same RV lock remote control that has been paired with the PCB board to pair with the RV main door lock;

[0022] Three-level control PCB board pairing: RV lock remote control pairing with PCB board.

[0023] Power docking control logic:

[0024] a. When powered by built-in power supply, only the 6V output interface outputs power, and the 12V switch power output interface is disabled; when powered by the vehicle power supply of 12V, the 6V output interface and the 12V switch output interface output power at the same time;

[0025] b. Definition of power output interface: 6V output interface, outputs positive and negative fixed power, and powers off after a delay of 6S; 12V switching power interface, outputs positive and negative switching power (controls the switch of the lock by switching the positive and negative poles), and powers off after a delay of 0.5S;

[0026] c. If the vehicle power supply is selected, the built-in power supply does not have a battery installed.

[0027] Press the remote control pairing button and the door lock pairing button at the same time to restore the original settings and complete the reset. BRIEF DESCRIPTION OF THE DRAWINGS

The battery 2 is installed between the positive electrode connecting piece 21, the negative electrode connecting piece 22 and the positive and negative electrode connecting piece 23 according to the positive and negative poles. Either the battery 2 or the vehicle power input 2P socket 32 ​​can be configured, that is, the power supply of the central control box can be supplied by the vehicle power input 2P socket 32 ​​or by the battery 2.

[0044] Two sets of gaskets 6 are arranged between the box cover 5 and the battery 2 .

[0045] The above central control box can achieve three levels of control, specifically:

[0046] The first-level control is controlled by the central control in the cab, which controls the opening and closing of the cab door lock, the RV main door lock and the hatch door lock, and the 12V power box cabinet lock at the same time. During this process, the 12V alternating power output 2P socket 34 outputs a 12V alternating voltage signal to control the PCB board to send out a radio frequency signal to control the RV door lock switch. At the same time, the PCB board controls the opening or closing of the hatch door lock and the 12V power box cabinet lock by turning the power on and off, that is, the car central control device simultaneously controls the opening or closing of the RV lock, the cab door lock, the hatch door lock and the 12V power box cabinet lock.

[0047] Primary control logic: The cab central control sends pulse electricity to the PCB control board and the cab door lock, and the cab door lock is opened or closed (open or closed is controlled by positive or negative voltage). At the same time, the PCB sends out an open or closed radio frequency signal, and the RV main door lock receives the open or closed signal to open or close the lock. At the same time, the PCB controls the power supply to power on or off the hatch lock or the 12V power cabinet lock. The hatch lock and cabinet lock are switched on and off by turning the power on and off.

[0048] The secondary control is controlled by the RV door lock remote control, which simultaneously controls the opening and closing of the RV main door lock, hatch door lock, and 12V power box cabinet lock.

[0049] Secondary control logic: The RV main door lock remotely controls the PCB controller. The PCB sends out an open or closed radio frequency signal. The RV main door lock receives the open or closed signal and performs an unlocking or locking action. At the same time, the PCB controls the power supply to power on or off the hatch lock and the 12V power box cabinet lock. The hatch lock and the 12V power box cabinet lock are turned on and off by turning the power on and off.

[0050] The third-level control is an independent remote control, which only controls the opening and closing of the hatch lock or the 12V power box cabinet lock.

[0051] Three-level control logic: The RV main door lock remote control PCB controller only controls the hatch lock or 12V power box cabinet lock switch.

[0052] Secondary control and tertiary control are realized through the group keys of the RV main door lock remote control. The RV door lock remote control is used to simultaneously control the opening or closing of the RV main door lock, hatch door lock, and 12V power box cabinet lock.

[0053] The coding includes three levels:

[0054] Primary control PCB board code matching: PCB board and RV main door lock code matching;

[0055] Secondary control PCB board pairing: After the RV lock remote control is paired with the PCB board, use the switch group of the same RV lock remote control that has been paired with the PCB board to pair with the RV main door lock;

[0056] Three-level control PCB board pairing: RV lock remote control pairing with PCB board.

[0057] Power docking control logic:

[0058] a. When powered by built-in power supply, only the 6V output interface outputs power, and the 12V switch power output interface is disabled; when powered by the vehicle power supply of 12V, the 6V output interface and the 12V switch output interface output power at the same time;

[0059] b. Definition of power output interface: 6V output interface, outputs positive and negative fixed power, and powers off after a delay of 6S; 12V switching power interface, outputs positive and negative switching power (controls the switch of the lock by switching the positive and negative poles), and powers off after a delay of 0.5S;

[0060] c. If the vehicle power supply is selected, the built-in power supply does not have a battery installed. The 12V alternating power supply output 2P socket 34 outputs a positive and negative pole switching power supply, controls the switch of the lock by the positive and negative pole switching, and powers off after a delay of 0.5s; the 6V fixed power supply output 2P socket 33 outputs a positive and negative pole fixed power supply, and powers off after a delay of 6s;

[0061] In the above scheme,

[0062] Control priority: cab central control > RV lock remote control (if there is a cab central control, there is no need for an additional remote control, use the remote control or central control switch that comes with the cab central control).

[0063] Control connection door locks: cab door lock - RV main door lock - hatch door lock - 12V power box cabinet lock;

[0064] The connection mode between the lock and the controller: central door lock (cab door lock) wired connection - RV main door lock wireless (radio frequency signal) connection - hatch lock wired (fixed power on / off) connection / 12V cabinet lock wired (switching power on / off) connection;

[0065] Press the remote control pairing button and the door lock pairing button at the same time to restore the original settings and complete the reset.

[0066] The above-mentioned embodiments only express several feasible implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention, and the embodiments are not used to limit the scope of protection in the claims of the present invention.
