[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] Reference below Figure 1-Figure 2 A control device 1 for a vehicle battery according to an embodiment of the present invention is described, and the control device 1 includes a first contact terminal 11, a second contact terminal 12, a movable component 13, and a drive assembly 14. The first contact terminal 11 and the second contact terminal 12 are spaced apart to form a contact channel, at least a portion of the movable component 13 can move into the contact channel and is suitable for connecting the first contact terminal 11 with the second contact terminal 12 when at least a portion of the movable component 13 moves into the moving channel, and the drive assembly 14 is suitable for controlling the movable component 13 to move after a preset condition is reached to control at least a portion of the movable component 13 to connect or disconnect the first contact terminal 11 with the second contact terminal 12.

[0030] In the related art, when a vehicle is left idle for a long time, if the battery is not disconnected, the battery will consume electricity along with the electrical system equipment on the vehicle, resulting in a battery power shortage problem. Currently, the battery is usually disconnected manually to address the above problem. When manually disconnecting, a wrench is required to loosen the negative electrode nut to further disconnect the negative electrode connection line from the battery. Since the on-board tools do not provide a wrench for loosening the negative electrode nut, the difficulty and complexity of the battery disconnection operation are increased.

[0031] Specifically, combined Figure 1 and Figure 2 As shown, the first contact terminal 11 and the second contact terminal 12 are arranged at intervals in the moving direction of the driving component, and the first contact terminal 11 and the second contact terminal 12 are spaced apart to form a contact channel. At least a portion of the movable component 13 is suitable for moving in the contact channel. An energized conductor is formed inside the movable component 13, one end of the energized conductor can be electrically connected to the first contact terminal 11, and the other end of the energized conductor can be electrically connected to the second contact terminal 12. When the movable component 13 is in a specific position, the energized conductor can be electrically connected to the first contact terminal 11 and the second contact terminal 12, so as to be suitable for conducting the first contact terminal 11 and the second contact terminal 12.

[0032] Among them, the first contact terminal 11 and the second contact terminal 12 can be fixed on the battery protection cover and spaced apart to form a contact channel, but not limited to this, the first contact terminal 11 and the second contact terminal 12 can also be on the mounting surface outside the battery, such as the sheet metal of the vehicle body, the internal bracket and other structures. Further, the drive component 14 can control the movement of the movable part 13 after the preset conditions are met, and the drive component 14 controls the movement of the movable part 13 to control the connection or disconnection between at least part of the movable part 13 and the first contact terminal 11 and the second contact terminal 12, thereby switching the control device 1 between the on state and the off state. In the on state, the first contact terminal 11 and the second contact terminal 12 are connected, and the wiring harness between the battery and the load is connected, thereby allowing the vehicle load to work normally.

[0033] In the disconnected state, the first contact terminal 11 is disconnected from the second contact terminal 12, and the wiring harness between the battery and the load is disconnected, thereby ensuring that the battery power is protected when the vehicle is not working, increasing the service life of the battery and reducing unnecessary energy consumption.

[0034] In short, according to the control device 1 for a vehicle battery of the present invention, the drive component 14 of the control device 1 can control the movement of the movable part 13 to ensure that at least a portion of the movable part 13 is suitable for moving in the contact channel, and by controlling the movement of the movable part 13, the conduction or disconnection between the first contact terminal 11 and the second contact terminal 12 is achieved. The control device 1 can achieve the conduction or disconnection of the battery. When the vehicle is left idle for a long time, the control device 1 can protect the power of the vehicle's battery by disconnecting the battery, thereby increasing the service life of the battery.

[0035] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown, the driving component 14 includes a driving element 141 and a movable sleeve 142. The movable sleeve 142 is dynamically connected to the driving element 141. The driving element 141 can drive the movable sleeve 142 to move, wherein the moving direction of the movable sleeve 142 intersects with the moving direction of the movable component 13. A connecting channel 1421 is provided on the movable sleeve 142. The connecting channel 1421 can accommodate the movable component 13. The movement of the movable sleeve 142 is controlled by the driving element 141, and the movable component 13 is moved in the connecting channel 1421, so that at least a part of the movable component 13 is connected or disconnected with the first contact end 11 and the second contact end 12.

[0036] According to one embodiment of the present invention, Figure 1 and Figure 2As shown, the connection channel 1421 passes through the movable sleeve 142, so that the movable component 13 can move more easily in the connection channel 1421. When the contact channel is directly opposite to the connection channel 1421, the movable component 13 can be separated from the contact channel under the action of external force, and the separated movable component 13 passes through the connection channel 1421 and protrudes from the surface of the movable sleeve 142. When the movable component 13 is separated from the contact channel, the control device 1 is in a disconnected state, the wiring harness between the battery and the load is disconnected, and the battery no longer consumes electricity.

[0037] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown, the control device 1 further includes a first reset member 15, wherein the first reset member 15 can be constructed as a spring or other elastic element. One end of the first reset member 15 is arranged on the bottom wall of the contact channel, and the other end of the first reset member 15 is connected to the movable component 13. When the control device 1 is in the conducting state, at least part of the movable component 13 is connected to the first contact end 11 and the second contact end 12, and the first reset member 15 is in a compressed state. When the control device 1 is in the disconnecting state, the contact channel is directly opposite to the connecting channel 1421, and the first reset member 15 can provide a thrust to the movable component 13, thereby driving the movable component 13 to disengage from the contact channel and protrude from the surface of the moving sleeve 142.

[0038] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown, the control device 1 also includes a second reset member 16, wherein the second reset member 16 can be constructed as a spring or other elastic element. One end of the second reset member 16 is arranged on the vehicle body, and the other end of the second reset member 16 abuts against the movable sleeve 142. When the control device 1 is in the disconnected state, the driving element 141 controls the movable sleeve 142 to move in the direction of the second reset member 16, at which time the second reset member 16 is in a compressed state, and the movable component 13 is disengaged from the contact channel and protrudes from the surface of the movable sleeve 142. When the control device 1 is in the conducting state, the second reset member 16 provides a thrust to the movable sleeve 142, so that the movable component 13 is in the contact channel, and the first contact end 11 and the second contact end 12 are conducting.

[0039] According to one embodiment of the present invention, the movable sleeve 142 is configured as a hollow sleeve, which can further reduce the cost of the movable sleeve 142, and the movable sleeve 142 can be configured as a hollow sleeve to reduce the weight of the movable sleeve 142. The space inside the hollow sleeve can be used to accommodate the movable component 13, thereby improving the compactness of the control device 1. In addition, a positioning hole is formed on the side of the movable sleeve 142, the connecting channel 1421 is connected to the positioning hole, and at least part of the movable component 13 is located in the movable sleeve 142. When the control device 1 is in the disconnected state, the movable component 13 can pass through the positioning hole to protrude from the surface of the movable sleeve 142. At this time, the user can press the movable component 13 protruding from the surface of the movable sleeve 142 to make the movable component 13 re-enter the interior of the movable sleeve 142, thereby making the control device 1 enter the conducting state.

[0040] Specifically, the movable sleeve 142 has a guide notch on one side facing the first contact end 11 and the second contact end 12, and the extension direction of the guide notch is the same as the moving direction of the movable sleeve 142. When the movable sleeve 142 moves to the connection channel 1421 and faces the movable component 13, the movable component 13 enters the connection channel 1421 and disengages from the contact channel to disconnect the first contact end 11 from the second contact end 12, thereby putting the control device 1 in a disconnected state. According to one embodiment of the present invention, in combination with Figure 1 and Figure 2 As shown, the driving element 141 includes a driving motor 1411 and a tray 1412. One end of the tray 1412 is connected to the driving end of the driving motor 1411, and the other end of the tray 1412 is in contact with the moving sleeve 142. The driving motor 1411 can drive the tray 1412 to move, and the tray 1412 provides thrust to the moving sleeve 142 to push the moving sleeve 142 to move until the connecting channel 1421 is aligned with the contact channel, so that the control device 1 is switched from the on state to the off state, and the driving element 141 can provide power for the movement of the moving sleeve 142.

[0041] According to one embodiment of the present invention, the control device 1 also includes a controller, which is electrically connected to the drive motor 1411. The controller can obtain an engine shutdown signal and an engine start signal. When the vehicle is shut down for a preset time, the controller can control the drive motor 1411 to drive the tray 1412 to move, so that the movable component 13 disconnects the first contact end 11 from the second contact end 12.

[0042] In a specific implementation of the present invention, when the controller starts to calculate the vehicle's shutdown time, if the shutdown time does not reach the specified time, the engine is started again. At this time, a signal is transmitted to the controller, and the controller's timing is reset to zero until the controller receives the engine's shutdown signal again and starts to recalculate. The timing time of the controller can be adjusted according to different vehicle models.

[0043] According to one embodiment of the present invention, the first contact terminal 11 is connected to the negative pole of the battery, and the second contact terminal 12 is connected to the load. When the battery is disconnected, the negative pole of the battery needs to be disconnected first, and when the battery is connected, the negative pole of the battery needs to be connected last. Therefore, the first contact terminal 11 is connected to the negative pole of the battery, and the second contact terminal 12 is connected to the load, which meets the technical requirements for disconnecting or connecting the battery, wherein the load can be other electrical components of the vehicle.

[0044] The control method according to the present invention is briefly described below.

[0045] According to the control method of the control device of the above embodiment of the present invention, the control method comprises the following steps:

[0046] S1, start timing after the engine is turned off. Specifically, the control system of the vehicle starts timing after the engine is turned off, and compares the time of the engine turning off with a preset time.

[0047] S2, if the timing reaches the preset time and the engine has not started, the driving assembly 14 controls the movable component 13 to move to disconnect the first contact end 11 from the second contact end 12.

[0048] S3, if the timing does not reach the preset time, the engine starts, and the timing is reset to zero. If the vehicle control system starts timing but does not reach the specified time, the engine starts again. At this time, the vehicle control system receives a signal, and the timing of the vehicle control system is reset to zero.

[0049] The preset time can be 10-20 days. Engineers can adjust the preset time according to different vehicle models. This control method can avoid the problem of battery power loss caused by long-term parking, thereby saving the battery power of the vehicle, avoiding unnecessary energy consumption, and increasing the service life of the vehicle battery.
