[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0036] The embodiments of the present invention provide a vehicle-mounted charger protection device and system, which can solve the technical problems that the existing automatic power-off protection system is relatively complex, prone to misoperation, and has high manufacturing and use costs.

[0037] Figure 1 An embodiment of the present invention provides an on-board charger protection device for protecting an on-board charger 2 located in a recess 3 in a vehicle luggage compartment. The device comprises a lifting device 1 and a vehicle controller. The lifting device 1 is located in the recess 3 in the vehicle luggage compartment and is used to support the on-board charger 2. The vehicle controller is connected to the lifting device 1 and is used to obtain a vehicle collision signal and control the lifting device 1 to lift the on-board charger 2 beyond the top of the recess 3 in the vehicle luggage compartment when the collision signal exceeds a preset value.

[0038] An on-board charger protection device according to an embodiment of the present invention includes a lifting device and a vehicle controller. The lifting device is located in the vehicle's luggage compartment recess and is used to support the on-board charger. The vehicle controller is connected to the lifting device and is used to obtain a vehicle collision signal and control the lifting device to lift the on-board charger above the top of the vehicle's luggage compartment recess when the collision signal exceeds a preset value. The on-board charger protection device is used to protect the on-board charger located in the vehicle's luggage compartment recess. When a collision occurs in the vehicle's luggage compartment, the on-board charger may be squeezed and leaked within the vehicle's luggage compartment recess due to vehicle body deformation. The vehicle controller obtains the vehicle collision signal and controls the lifting device to lift the on-board charger above the top of the vehicle's luggage compartment recess when the collision signal exceeds a preset value, causing the on-board charger to move toward the top of the vehicle's luggage compartment recess. This changes the movement path of the on-board charger and prevents the on-board charger from being squeezed within the vehicle's luggage compartment recess. This eliminates the need for an automatic power-off protection system, avoids misoperation, and reduces manufacturing and use costs.

[0039] As an optional implementation, in one embodiment of the invention, see Figure 1As shown, the on-board charger protection device also includes: a collision sensor, which is connected to the vehicle controller and is arranged at the rear end of the vehicle, for collecting the collision signal of the rear end of the vehicle and sending it to the vehicle controller. The collision sensor is a collision intensity sensor, which is used to detect the degree of collision of the car. It is installed at the rear end of the vehicle as a rear collision intensity sensor. The collision sensor senses the force or speed changes generated when the rear end of the vehicle collides and converts these changes into electrical signals and transmits them to the vehicle controller. The vehicle controller compares the collision signal transmitted by the collision sensor with the preset value of 20km / h. When the collision signal exceeds the preset value of 20km / h, the vehicle controller controls the lifting device to lift the on-board charger. The collision sensor has higher sensitivity, larger detection range and higher reliability, and can be integrated with other sensors, controllers, actuators and other equipment to achieve more intelligent and automated applications.

[0040] As an optional implementation, in one embodiment of the invention, see Figure 1 and Figure 2 As shown, the lifting device 1 includes a plurality of lifting units 11, two of the lifting units 11 are spaced apart on one side of the on-board charger 2, and a lifting unit 11 is correspondingly provided at a top corner of one side of the on-board charger 2. When the collision signal exceeds a preset value of 20 km / h, the vehicle controller controls the lifting unit 11 to rise and thereby lift the on-board charger 2, so that the on-board charger 2 exceeds the top of the vehicle luggage compartment groove 3; in addition, a lifting unit 11 can be correspondingly provided on one side of the on-board charger 2, and a lifting unit 11 corresponding to the on-board charger 2 can be provided above each lifting unit 11. A fixing plate of the same length as the charger 2, both ends of the fixing plate are respectively connected to the on-board charger 2, the middle part of the fixing plate is located above the lifting unit 11, when the collision signal exceeds the preset value of 20km / h, the vehicle controller controls the lifting unit 11 to rise, and the fixing plate rises with the lifting unit 11 and then lifts the on-board charger 2 so that it exceeds the top of the vehicle luggage compartment groove 3. By setting the fixing plate, the number of the lifting units 11 can be reduced. Only two lifting units 11 are provided at the bottom of the on-board charger 2 to lift the on-board charger 2, thereby reducing the cost of use.

The middle of the fixed bracket 113 is connected to the support platform 112, and the two ends of the fixed bracket 113 are respectively connected to the bottom plate of the vehicle luggage compartment groove 3. The lifting motor 111 is connected to the vehicle controller, and the vehicle controller controls the action of the lifting motor 111 to further control the telescopic shaft 1111 to rise. The telescopic shaft 1111 extends to the outside of the support platform 112 and the fixed bracket 113 and is connected to the on-board charger 2. The telescopic shaft 1111 rises and lifts the on-board charger 2. The support platform 112 is provided above the lifting motor 111, and is used to form a plane at the top of the lifting motor 111 and be connected to the fixed bracket 113. The middle part of the fixed bracket 113 is connected to the support platform 112, and the two ends of the fixed bracket 113 are respectively fixedly connected to the bottom plate of the vehicle luggage compartment groove 3. The lifting motor 111 is fixed in the vehicle luggage compartment groove 3 through the support platform 112, so that the lifting motor 111 will not shake or displace during vehicle driving, and the lifting motor 111 is supported under the on-board charger 2.

The middle part of the support block 114 is a hollow structure, and the size of the through hole in the middle of the support block 114 matches the size of the telescopic shaft 1111, and is used to be sleeved on the outside of the telescopic shaft 1111. Since the fixed bracket 113 is fixedly connected to the bottom plate of the vehicle luggage compartment groove 3, the support block 114 is arranged above the fixed bracket 113, so that when the telescopic shaft 1111 rises, the support block 114 can be driven to rise.

When the telescopic shaft 1111 rises, it drives the support block 114 to rise, and the rise of the support block 114 further drives the support foot 4 to rise. The rise of the support foot 4 further lifts the on-board charger 2, so that the on-board charger 2 is located at the top of the vehicle luggage compartment groove 3 after the vehicle collision and moves at the top of the vehicle luggage compartment groove 3, changing the movement path of the on-board charger 2, preventing the on-board charger 2 from being squeezed inside the vehicle luggage compartment groove 3 and leaking electricity, thereby protecting the on-board charger 2.
