[0018] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of this application.

[0019] Example: This application provides a new energy storage battery with a protective function. By optimizing the overall structure of the battery and the design of each component, the battery's impact resistance is improved, the battery core is effectively protected, and good heat dissipation and combustion protection performance are achieved. The safety and stability of the battery are improved and the battery life is extended. For details, please refer to Figures 1-16 , including a battery assembly 5 and a shell 1 for covering the battery assembly 5. See also Figure 2-Figure 6 A battery rack 4 is fixed in the shell 1. The battery rack 4 includes a central axis mounting base 42 fixed in the shell 1. Two sets of mounting frames 41 are symmetrically connected to the two sides of the central axis mounting base 42. The two sets of mounting frames 41 are tilted downward on the sides away from each other, and two sets of symmetrically arranged buffer slides 412 are provided on the top of the sides away from each other. An electromagnetic buffer system 6 that cooperates with the buffer slides 412 is provided in the shell 1.

[0020] Please refer to 13- Figure 14Through the cooperation between the electromagnetic buffer system 6 and the buffer slide 412, when the battery is impacted, the electromagnetic buffer system 6 can control the movement of the buffer slide 412 to achieve buffering and shock absorption of the mounting frame 41, effectively reducing the impact of the impact on the battery assembly 5. It should be noted that the electromagnetic buffer system 6 of the present application works based on the electromagnetic principle, and its structure is the automobile electromagnetic buffer structure in the prior art. It realizes the buffering function by controlling the current and magnetic field. The electromagnetic buffer system 6 is linked through a communication protocol, such as the CAN bus protocol, to realize data interaction and sharing with the automobile central control system. During the driving process of the automobile, the electromagnetic buffer system 6 is coordinated and managed by the central control system, and the central control system uniformly controls and dispatches the electromagnetic buffer system 6 according to the overall operating status and needs of the automobile.

[0021] In addition, the electromagnetic buffer system 6 of the present application is equipped with attitude sensors, such as acceleration sensors, collision sensors, etc., which can obtain various dynamic data of the car during driving, such as vehicle speed, acceleration, and collision intensity in real time, and transmit these data to the electromagnetic buffer system 6 of the present application in real time. It can adjust its own buffering parameters in advance according to the driving status of the car and potential impact risks, thereby improving the protection effect of the battery assembly 5.

[0022] Specifically, when the vehicle is bumpy during operation, the mounting frame 41 will tend to vibrate. At this time, the attitude sensor detects the sensor data, and the buffer slide 412 slides relative to the buffer slide groove 112 under the impact. The electromagnetic induction device in the electromagnetic buffer system 6 monitors the position and movement state of the buffer slide 412 in real time, and transmits the signal to the central control system. The central control system analyzes the signal to determine parameters such as the direction, intensity and duration of the vibration impact, and then adjusts the output current and magnetic field strength of the electromagnetic buffer system 6 according to the preset program and algorithm. By changing the magnitude and direction of the electromagnetic force, a reverse force is applied to the buffer slide 412, thereby slowing down the displacement speed and amplitude of the mounting frame 41, thereby achieving buffer protection for the battery assembly 5.

[0023] In another application scenario, when the vehicle tilts left or right while moving forward, such as in an off-road state, the battery assembly 5 on one side will be closer to the ground. In order to avoid an increased risk of collision between the battery assembly 5 on this side and ground obstacles, the electromagnetic buffer system 6 on this side can lift the mounting frame 41 on the corresponding side, so that the height of the mounting frame 41 is increased, thereby reducing the risk of collision of the battery assembly 5 due to the tilted posture of the vehicle.

[0024] See also Figure 5-Figure 11The two groups of battery assemblies 5 are symmetrically fixed in the corresponding mounting frames 41, and the inclination angle of the battery cells 54 on the horizontal plane is 30°. The mounting frame 41 has an inclination angle on the vertical plane. The optimized design angle can better achieve the dispersion of inertial force and support of the battery assembly 5. Specifically, the battery assembly 5 is assembled from a number of equidistant and inclined battery cells 54, and the battery cells 54 are inclined in the opposite direction of the vehicle's forward movement. Such an arrangement can utilize the inclination angle of the battery cells 54 to effectively disperse the frontal impact force of the vehicle on the battery cells 54 due to collision during the vehicle's driving. At the same time, during the rapid acceleration and deceleration of the vehicle, the electromagnetic buffer system 6 can be used to reduce and then increase the buffering resistance of the mounting frame 41. At this time, the inertial force generated during the rapid speed change of the vehicle will push the two groups of mounting frames 41 to move up the deflection design angle, converting the potential energy into the deflection kinetic energy of the mounting frame 41, thereby effectively reducing the mutual squeezing force between the battery cells 54 during the rapid speed change of the car.

[0025] Both ends of the battery cell 54 are provided with end seats 52, and a connecting seat 53 is fixed on one side of the end seat 52. Two groups of symmetrically arranged positioning holes 531 are provided on the side of the connecting seat 53 away from the end seat 52. The end of the battery cell 54 is provided with a positioning pin 541 that cooperates with the positioning hole 531. Through the cooperation between the positioning pin 541 and the positioning hole 531, the battery cell 54 can be quickly assembled and installed between the two groups of end seats 52.

[0026] The end seat 52 is rotatably connected to the side away from the battery cell 54 with a ball 521. Both sides of the inner wall of the mounting frame 41 are provided with assembly grooves 411 that cooperate with the ball 521. The ball 521 rolls in the assembly grooves 411, making the installation of the battery assembly 5 in the mounting frame 41 more convenient and flexible, and can further buffer external impacts. See also Figure 7-10 A protective plate 51 is provided between adjacent battery cells 54. Bolt holes 511 are provided at both ends of the protective plate 51. The protective plate 51 is fixed to the two sets of connecting seats 53 through the bolt holes 511. One side of the protective plate 51 is provided with a C-shaped groove 515 for loading the battery cells 54, and the other side is provided with a heat exchange capsule 512. The C-shaped groove 515 can fix and protect the battery cells 54 and prevent the battery cells 54 from shifting within the battery assembly 5. The heat exchange bladder 512 effectively absorbs and transfers the heat generated by the battery cells 54 during operation. Two sets of symmetrically positioned hooks 513 are located at the upper and lower ends of one side of the protective plate 51, while two sets of symmetrically positioned hook slots 514 are located at the upper and lower ends of the other side. The hook slots 514 of adjacent protective plates 51 interlock with the hooks 513, creating a tighter and more stable connection between the protective plates 51, further enhancing the protection provided to the battery cells 54. The heat exchange bladder 512 is filled with coolant, which is perfluorohexanone coolant with good fire extinguishing performance and electrical insulation performance. The heat exchange bladder 512 has built-in pressure sensor and temperature sensor. The input and output ends of the heat exchange bladder 512 are equipped with electromagnetic valves. The pressure sensor, temperature sensor and electromagnetic valve are all electrically connected to the vehicle's central control system.

[0027] In a normal application scenario, after multiple groups of battery cells 54 are installed in the mounting frame 41, the electromagnetic valve is used to increase the pressure in each heat exchange capsule 512 to a fixed design value, thereby displacing adjacent battery cells 54 and fixing the relative position of the end seat 52 and the assembly slide 411. On the one hand, the assembly and positioning action of the multiple groups of battery cells 54 is completed, and on the other hand, the expanded heat exchange capsule 512 is used to form a buffer space between adjacent battery cells 54. In the heat dissipation scenario, the pressure sensor and temperature sensor monitor the pressure and temperature of the coolant in the protective plate 51 in real time. When the temperature rises, the electromagnetic valve opens, and the coolant circulates to remove the heat generated by the battery cells 54, thereby achieving efficient heat dissipation. Please refer to the Figure 15-16 In a vehicle collision scenario, when a local battery cell 54 is hit, the pressure sensor in the heat exchange bladder 512 at the impact site detects a sudden change in the pressure value of the heat exchange bladder 512. Combined with the vehicle's own acceleration sensor and collision sensor, the central control system determines that a battery collision accident has occurred. At this time, the heat exchange bladder 512 outside the collision site reduces pressure through the electromagnetic valve, shrinks the gap between adjacent battery cells 54, and makes room for both sides of the battery cell 54 at the collision site. The cooling hydraulic pressure is concentrated in the heat exchange bladder 512 that has been hit, and the over-expanded heat exchange bladder 512 is used to separate the battery cell that has been hit from the battery cell that has not been hit. At the same time, the battery cells on both sides of the collision bladder 512 are The end seat 52 is in a free state, and subsequent impacts will cause the battery cell 54 to deflect, which on the one hand cushions the impact force, and on the other hand makes the impact port face downward to prevent the impact port from burning and causing personal injury. When the battery cell 54 is hit and catches fire, the heat will burn the adjacent and expanded heat exchange sac 512. At this time, the perfluorohexanone coolant in the heat exchange sac 512 leaks and is released. The perfluorohexanone coolant can evaporate quickly, absorb a large amount of heat, and reduce the battery temperature. At the same time, its steam can isolate the air and inhibit the combustion reaction, thereby effectively extinguishing the battery fire. At the same time, perfluorohexanone is environmentally friendly and will not cause damage to equipment and personnel, thereby achieving a fire extinguishing and protection effect after a battery collision.

[0028] See also Figure 2 and Figure 11-12The shell 1 includes an upper box body 11 and a lower cover plate 12. Side anti-collision beams 111 are fixed on both sides of the upper box body 11. The top of the upper box body 11 is also provided with an electronic control unit 2. A buffer slide groove 112 is provided in the upper box body 11 to cooperate with the buffer slide column 412. The side anti-collision beam 111 can enhance the shell 1's ability to resist lateral impact and protect the internal structure of the battery; the buffer slide groove 112 cooperates with the buffer slide column 412 to further improve the buffering effect.

[0029] The lower sealing plate 12 is encapsulated at the bottom of the upper box body 11. The thickness of the middle part of the lower sealing plate 12 is greater than the thickness of the two sides. The bottom of the lower sealing plate 12 is also provided with a V-shaped reinforcement part 121. This structural design can effectively enhance the strength and stability of the bottom of the shell 1. When the bottom is hit, the V-shaped reinforcement part 121 will transfer the impact point of the obstacle to the two sides of the lower sealing plate 12, thereby enabling the upward deflection action of the mounting frame 41 to more effectively protect the battery. Please refer to the Figure 6 A plurality of rivet holes 421 are provided on the central axis mounting seat 42, and the central axis mounting seat 42 is fixed to the inner side of the upper box body 11 through the rivet holes 421. A connecting shaft 422 is fixed to the top of the central axis mounting seat 42, and the two groups of mounting frames 41 are rotatably connected on the connecting shaft 422. A central axis buffer pad 44 is also clamped between the opposite sides of the two groups of mounting frames 41. The central axis buffer pad 44 has an elastic force that drives the two groups of mounting frames 41 away from each other. When subjected to a lateral impact, the central axis buffer pad 44 can further buffer the interaction force between the mounting frames 41. Please refer to the Figure 4-Figure 5 The mounting frame 41 has a diamond-shaped frame structure, and the four diamond-shaped corners of the mounting frame 41 are rotatably connected. An X-shaped tie bar 43 is also provided on the top of the mounting frame 41. The four ends of the X-shaped tie bar 43 are rotatably connected to the four diamond-shaped corners of the mounting frame 41 respectively. The structural strength of the X-shaped tie bar 43 is less than the structural strength of the mounting frame 41. This structural design enables the mounting frame 41 to have a certain elastic deformation ability while ensuring strength. Combined with the inclined placement of the battery assembly 5, it can better absorb impact energy. A protective layer 3 is also provided on the inner top of the upper box body 11, and the protective layer 3 is arranged between the upper box body 11 and the battery assembly 5. The protective layer 3 includes two groups of symmetrically arranged middle protective pads 32, and the two ends of the two groups of middle protective pads 32 are respectively fixed with a head protective block 31 and a tail protective block 33. An assembly gap 301 is provided between the two groups of middle protective pads 32 to facilitate the installation of the middle axis mounting seat 42 and the upper box body 11. The cross-section of the middle protective pad 32 is a triangular structure. The middle protective pad 32 has an elastic force that drives the battery assembly 5 away from the upper box body 11 to buffer the impact force of the upward deflection of the mounting frame 41. The head protective block 31 is arranged in the direction of the vehicle's advancement and has a slope that guides the impact force to be distributed to both sides of the vehicle. The tail protective block 33 is arranged in the opposite direction of the vehicle's advancement. A buffer layer is provided in the head protective block 31 and the tail protective block 33. The protective layer 3 can effectively prevent the battery assembly 5 from being impacted and squeezed from the front and rear directions and above of the vehicle.

[0030] The present invention comprises a battery rack 4 with a buffering function through a central axis mounting seat 42, a mounting frame 41, a buffer slide 412 and an electromagnetic buffer system 6, which can effectively buffer and reduce shock when the battery is subjected to external impact or vibration, thereby protecting the battery assembly 5 and improving the battery's impact resistance. At the same time, the inclined setting of the battery cells 54 and the design of the protective plate 51 between the battery cells 54 can not only disperse the inertial force and reduce the extrusion between the battery cells, but also achieve efficient heat dissipation through the coolant and heat exchange sac in the protective plate, ensuring that the battery cells operate at an appropriate temperature, extending the battery life, and can autonomously separate abnormal battery cells 54 in an impact scenario, and actively perform fire extinguishing operations when a fire occurs, further improving the battery's impact resistance. The above is only the best implementation method adopted by this application in combination with current actual needs, but the scope of protection of this application is not limited to this.
