[0061] An embodiment of the present application provides a vehicle, the vehicle comprising: a vehicle body and a battery protection device disposed at the bottom of the vehicle body;

[0062] See also Figures 1 to 3 The battery protection device comprises: a battery body 1, a first frame 2 and a second frame 3; wherein the battery body 1, the first frame 2 and the second frame 3 are arranged in sequence from bottom to top;

[0063] A plurality of cutting plates 4 are disposed in the inner cavity of the first frame 2, and the cutting plates 4 extend to one side outside the first frame 2 and are connected to a push block 5;

[0064] A connecting groove 6 is provided on the surface of the cutting plate 4, and inclined blocks 7 are provided on both sides of the inner cavity of the connecting groove 6, and the inclined blocks 7 are connected to the cutting blade 8;

[0065] The surface of the battery body 1 is provided with a first connection block 9, a second connection block 10 and a connection rod 11 in sequence from bottom to top;

[0066] The second connecting block 10 passes through the communicating groove 6 and extends to the inner cavity of the first frame 2;

[0067] The top of the connecting rod 11 extends to the inner cavity of the second frame 3 and is connected to the top of the inner cavity of the second frame 3;

[0068] The pushing block 5 is used to push the cutting board 4 to move when it is hit by external force;

[0069] The cutting plate 4 is used to drive the cutting knife 8 to cut the second connecting block 10 under the push of the pushing block 5; when the second connecting block 10 is cut off, the battery body 1 is disconnected from the first frame 2.

[0070] The embodiment of the present application provides a vehicle, when the vehicle body is hit by an external force, the push block 5 in the battery protection device pushes the cutting plate 4 to move, and the cutting plate 4 drives the cutting knife 8 to cut the second connecting block 10, and when the second connecting block 10 is cut off, the battery body 1 is disconnected from the first frame 2. It can be seen that when the vehicle is hit by an external force, the battery body 1 is disconnected from the first frame 2, so that safety accidents such as leakage and fire of the battery body 1 due to being squeezed can be avoided, thereby improving safety.

[0071] In the embodiment of the present application, the battery body 1 is fixedly connected to the first frame 2, and the first frame 2 is fixedly connected to the second frame 3. The fixed connection method in the embodiment of the present application can be set and changed as needed, for example, the fixed connection method is welding or other connection methods, which are not specifically limited.

[0072] Introduction to the first frame 2: continue to see Figure 1 A plurality of cutting boards 4 are arranged around the inner cavity of the first frame 2, and each cutting board 4 extends to one side outside the first frame 2 and is fixedly connected to a pushing block 5, so that when impacted in any direction, the pushing block 5 in that direction will push the cutting board 4 connected thereto to move.

[0073] For each cutting board 4, a connecting groove 6 is arranged on the surface of the cutting board 4, and inclined blocks 7 are arranged on both sides of the inner cavity of the connecting groove 6. The opposite sides of the two inclined blocks 7 are fixedly connected to the cutting blade 8. Figure 3 .

[0074] The size of the connecting groove 6 can be set and changed as needed, which is not specifically limited. The inclination angle of the tilting block 7 can be set and changed as needed, for example, 30°, 45° or 50°, which is not specifically limited. The material of the cutting knife 8 can be set and changed as needed, for example, the material of the cutting knife 8 is stainless steel or hard alloy, which is not specifically limited. The material of the cutting board 4 can also be set and changed as needed, which is not specifically limited.

[0075] Introduction of the battery body 1: In a possible implementation, a first connecting block 9, a second connecting block 10 and a connecting rod 11 are sequentially arranged on the surface of the battery body 1 from bottom to top.

[0076] In this implementation, the surface of the battery body 1 is fixedly connected to the first connection block 9, the top of the first connection block 9 is fixedly connected to the second connection block 10, and the top of the second connection block 10 is fixedly connected to the connection rod 11. The second connection block 10 passes through the connecting groove 6 and extends to the inner cavity of the first frame 2, and the top of the connection rod 11 extends to the inner cavity of the second frame 3 and is connected to the top of the inner cavity of the second frame 3.

[0077] In this implementation, the connecting rod 11 may be a rod with threads, and the connecting rod 11 is threadedly connected to the top of the inner cavity of the second frame 3 through the threads thereon.

[0078] In the embodiment of the present application, since the connecting groove 6 is arranged on the cutting plate 4, when the cutting plate 4 moves, the connecting groove 6 will move with the movement of the cutting plate 4. During the movement of the connecting groove 6, the cutting knife 8 will cut the second connecting block 10. When the second connecting block 10 is cut off, the battery body 1 is disconnected from the first frame 2.

[0079] One thing that needs to be explained is that the above is explained by taking the cutting knife 8 cutting the second connecting block 10 as an example. In the embodiment of the present application, the cutting knife 8 can also cut the first connecting block 9. If the cutting knife 8 cuts the first connecting block 9, the first connecting block 9 passes through the connecting groove 6 and extends to the inner cavity of the first frame 2; the top of the connecting rod 11 extends to the inner cavity of the second frame 3 and is connected to the top of the inner cavity of the second frame 3. In this implementation, during the movement of the connecting groove 6, the cutting knife 8 will cut the first connecting block 9. When the first connecting block 9 is cut off, the battery body 1 is disconnected from the first frame 2. It can be seen that the cutting knife 8 cutting the first connecting block 9 can also achieve the effect of separating the battery body 1 from the first frame 2.

[0080] Introduction to the second framework 3: In one possible implementation, see Figure 4 , the bottom surface of the second frame 3 and the surface of the cutting plate 4 are both provided with movable grooves 12;

[0081] The bottom of the inner cavity of the second frame 3 is connected to the push rod 13, and the bottom of the push rod 13 passes through the movable groove 12 and the bottom of the first frame 2, and contacts the surface of the battery body 1;

[0082] A connecting plate 14 and a spring 15 are sequentially arranged on the top of the push rod 13 from bottom to top, and the top of the spring 15 is connected to the top of the inner cavity of the second frame 3;

[0083] The spring 15 is used to reset the battery body 1 after it is disconnected from the first frame 2, and push the connecting plate 14 during the reset process;

[0084] The connecting plate 14 is used to push the battery body 1 through the pushing rod 13 under the push of the spring 15 to accelerate the separation from the first frame 2.

[0085] In this implementation, the push rod 13 passes through the movable groove 12 on the bottom surface of the second frame 3, the movable groove 12 on the surface of the cutting plate 4 and the bottom of the first frame 2, and contacts the surface of the battery body 1. In addition, the bottom of the inner cavity of the second frame 3 is movably connected to the push rod 13, the top of the push rod 13 is fixedly connected to the connecting plate 14, the top of the connecting plate 14 is fixedly connected to the spring 15, the top of the spring 15 is fixedly connected to the top of the inner cavity of the second frame 3, and the spring 15 is in a compressed state.

[0086] The materials of the connecting plate 14 and the pushing rod 13 can be set and changed as needed, and no specific limitation is made thereto.

[0087] In the embodiment of the present application, when the battery body 1 is disconnected from the first frame 2, the battery body 1 moves downward under the action of gravity, and the return elastic force of the spring 15 pushes the connecting plate 14. The lower end of the connecting plate 14 pushes the battery body 1 through the pushing rod 13, thereby accelerating the separation of the battery body 1 from the first frame 2.

[0088] In a possible implementation, a support rod 16 is provided at the bottom of the inner cavity of the second frame 3, and the top of the support rod 16 is connected to the top of the inner cavity of the second frame 3;

[0089] The support rod 16 is used to increase the support strength of the inner cavity of the second frame 3 .

[0090] In this implementation, the bottom of the inner cavity of the second frame 3 is fixedly connected to the support rod 16. By providing the support rod 16, the support capacity of the inner cavity of the second frame 3 can be increased, and the possibility of deformation of the second frame 3 due to force can be reduced.

[0091] In the embodiment of the present application, when the vehicle body is impacted by external force, the push block 5 is also impacted by external force. When the push block 5 is impacted by external force, it pushes the cutting plate 4 to move. Under the push of the push block 5, the cutting plate 4 drives the cutting knife 8 to cut the second connecting block 10 or the first connecting block 9. When the first connecting block 9 or the second connecting block 10 is cut off, the battery body 1 is disconnected from the first frame 2.

[0092] When the battery body 1 is disconnected from the first frame 2, the battery body 1 moves downward under the action of gravity, and the return elastic force of the spring 15 pushes the connecting plate 14. The lower end of the connecting plate 14 pushes the battery body 1, thereby accelerating the separation speed of the battery body 1 and the first frame 2. In this way, when the vehicle is hit, the battery body 1 and the first frame 2 are quickly disconnected and limited, avoiding safety accidents such as leakage and fire due to collision with external force, thereby improving safety.

[0093] Introduction of the third frame 17: In one possible implementation, continue to refer to Figure 1, the battery protection device further includes: a third frame 17;

[0094] One side of the battery body 1 is connected to the third frame 17, and a liquid level sensor 18 is arranged on the surface of the third frame 17;

[0095] The third frame 17 is used to contain a coolant for cooling the battery body 1;

[0096] The liquid level sensor 18 is used to monitor the liquid level of the coolant.

[0097] In this implementation, one side of the battery body 1 is fixedly connected to the third frame 17, and a liquid level sensor 18 is provided on the surface of the third frame 17. The liquid level sensor 18 monitors the liquid level of the coolant in the third frame 17 to prevent the liquid level from being too low and affecting the cooling function of the battery body 1.

[0098] It should be noted that the above description is based on the example that the liquid level sensor 18 is disposed on the surface of the third frame 17. In actual application, the liquid level sensor 18 may also be disposed on one side of the third frame 17, and this is not specifically limited.

[0099] In a possible implementation, one side of the third frame 17 is connected to the conduit 19, through which the coolant can be introduced into the third frame 17 or discharged from the third frame 17, thereby preventing the coolant level in the third frame 17 from being too high or too low.

[0100] Introduction of the temperature sensor 20, the infrared sensor 21 and the current sensor 22: In a possible implementation, continue to refer to Figure 2 The surface of the battery body 1 is also provided with a temperature sensor 20, an infrared sensor 21 and a current sensor 22;

[0101] A temperature sensor 20, used to monitor the temperature of the battery body 1;

[0102] The infrared sensor 21 is used to monitor the contact between the battery body 1 and the first frame 2;

[0103] The current sensor 22 is used to monitor the current on the surface of the battery body 1 .

[0104] In this implementation, the temperature of the surface of the battery body 1 can be monitored by the temperature sensor 20, whether the battery body 1 is in contact with the first frame 2 can be monitored by the infrared sensor 21, and whether there is current on the surface of the battery body 1 can be monitored by the current sensor 22, thereby achieving the function of monitoring and protecting the battery body 1.

[0105] In the embodiment of the present application, when the data monitored by the liquid level sensor 18, the temperature sensor 20, the infrared sensor 21 and the current sensor 22 are abnormal, an alarm may be issued. Figure 5 , the vehicle further comprises: a processor 23 and an alarm device 24;

[0106] The temperature sensor 20, the infrared sensor 21 and the current sensor 22 are all electrically connected to one end of the processor 23, and the other end of the processor 23 is electrically connected to the alarm device 24;

[0107] The processor 23 is used to receive the monitoring data sent by the temperature sensor 20, the infrared sensor 21 and the current sensor 22, and send an alarm message to the alarm device 24 if the monitoring value of any monitoring data is greater than the corresponding preset threshold value;

[0108] The alarm device 24 is used to generate an alarm based on the alarm message sent by the processor 23.

[0109] In this implementation, the temperature sensor 20, the infrared sensor 21 and the current sensor 22 can send their respective monitoring data to the processor 23. The processor 23 determines whether the monitoring value of any monitoring data is greater than its corresponding preset threshold. If it is greater than the preset threshold, the processor 23 sends an alarm message to the alarm device 24, thereby causing the alarm device 24 to sound an alarm.

[0110] For example, the processor 23 determines whether the temperature sent by the temperature sensor 20 is greater than a first preset threshold value. If so, the processor 23 sends an alarm message to the alarm device 24. The processor 23 determines whether the current sent by the current sensor 22 is greater than a second preset threshold value. If so, the processor 23 sends an alarm message to the alarm device 24. The processor 23 determines whether the distance between the battery body 1 and the first frame 2 sent by the infrared sensor 21 is greater than a third preset threshold value. If so, it indicates that the battery body 1 and the first frame 2 have been separated, and the processor 23 sends an alarm message to the alarm device 24.

[0111] In the embodiment of the present application, one end of the processor 23 is also electrically connected to the liquid level sensor 18, and the liquid level sensor 18 sends the liquid level it monitors to the processor 23. If the liquid level is less than the fourth preset threshold, the processor 23 sends an alarm message to the alarm device 24. The alarm device 24 issues an alarm based on the alarm message.

[0112] The temperature sensor 20, the liquid level sensor 18, the infrared sensor 21, the current sensor 22 and the alarm device 24 can be set and changed as needed. For example, the model of the temperature sensor 20 is JASUN-PDii-535, the model of the liquid level sensor 1824 is HM22, the model of the current and voltage sensor 25 is WBI413N25, the model of the infrared sensor 27 is CKF, and the alarm device 24 includes at least one of a buzzer and an alarm light. The buzzer is used to give an alarm through the sound it emits, and the alarm light is used to give an alarm through the flashing of the light.

[0113] It should be noted that the electrical connection in the embodiments of the present application may be a circuit connection or a wireless connection, wherein the wireless connection includes an infrared connection, a wireless local area network and a WiFi (Wireless Fidelity) network connection, which is not specifically limited.

[0114] In a possible implementation, the processor 23 may also send the received monitoring data to the remote terminal. Accordingly, the processor 23 is also used to be electrically connected to the terminal and send the received monitoring data to the terminal.

[0115] In this implementation, the target application is installed on the terminal, and the processor 23 sends monitoring data to the server of the target application. In response to the terminal logging into the target application, the server forwards the monitoring data to the terminal, so that the terminal displays the monitoring data. In this way, the user can remotely view the monitoring data of the battery body 1 by the temperature sensor 20, the liquid level sensor 18, the current sensor 22 and the infrared sensor 21, thereby improving the user experience.

[0116] In the embodiment of the present application, the battery body 1 is monitored and protected by a temperature sensor 20, a liquid level sensor 18, an infrared sensor 21 and a current sensor 22. Once the monitoring data exceeds a preset threshold or is less than a preset threshold, the alarm device 24 will sound an alarm, thereby facilitating the user to maintain the battery body 1 in a timely manner.

[0117] The present application embodiment provides a vehicle battery protection method, see Figure 6 , the method comprising:

[0118] Step 601: When the pushing block is hit by an external force, the cutting plate is pushed to move.

[0119] Step 602: The cutting plate is pushed by the pushing block to drive the cutting knife to cut the second connecting block.

[0120] Step 603: When the second connecting block is cut off, the battery body is disconnected from the first frame.

[0121] In a possible implementation, the method further includes:

[0122] After the battery body is disconnected from the first frame, the spring is reset, and during the reset process, the connecting plate is pushed;

[0123] The connecting plate, pushed by the spring, pushes the battery body through the pushing rod to accelerate the separation of the battery body from the first frame.

[0124] In another possible implementation, the method further includes:

[0125] The temperature sensor, infrared sensor and current sensor send their respective monitored data to the processor;

[0126] If any monitoring data is greater than the corresponding preset threshold, the processor sends an alarm message to the alarm device;

[0127] The alarm device issues an alarm based on the alarm message.

[0128] In another possible implementation, the method further includes:

[0129] The liquid level sensor sends the liquid level it monitors to the processor;

[0130] If the liquid level is less than a fourth preset threshold, the processor sends an alarm message to the alarm device;

[0131] The alarm device issues an alarm based on the alarm message.

[0132] The embodiment of the present application provides a vehicle battery protection method, in which when the push block is hit by an external force, the cutting plate is pushed to move, and the cutting plate drives the cutting knife to cut the second connection block. When the second connection block is cut off, the battery body is disconnected from the first frame. It can be seen that when the vehicle is hit by an external force, the battery body is disconnected from the first frame. Therefore, this method can avoid safety accidents such as leakage and fire of the battery body due to squeezing, thereby improving safety.
