DETAILED DESCRIPTION

[0039] The embodiments will be described in conjunction with the drawings in the specification, and all other embodiments obtained by those skilled in the art based on the embodiments in the application without creative labor shall fall within the scope of protection of the application.

[0040] Embodiment:

[0041] The application provides a new energy storage battery with a protection function. By optimizing the overall structure of the battery and the design of each component, the impact resistance of the battery is improved, the battery cell is effectively protected, good heat dissipation effect and combustion protection performance are realized, the safety and stability of the battery are improved, and the service life of the battery is prolonged. For details, please refer to Figures 1-16 , which comprises a battery assembly 5 and a shell 1 for covering the battery assembly 5.​

[0042] Please refer to Figures 2-6 The battery holder 4 is fixed in the shell 1, and the battery holder 4 comprises a middle shaft mounting seat 42 fixed in the shell 1, and two groups of mounting frames 41 are symmetrically and rotatably connected to the two sides of the middle shaft mounting seat 42, the sides away from each other of the two groups of mounting frames 41 are both downwardly inclined, and the top of the side away from each other of the two groups of mounting frames 41 is provided with two groups of symmetrically arranged buffer slide columns 412, and the shell 1 is provided with an electromagnetic buffer system 6 matched with the buffer slide columns 412.

[0043] Please refer to 13- Figure 14 Through the cooperation of the electromagnetic buffer system 6 and the buffer slide column 412, when the battery is impacted, the electromagnetic buffer system 6 can control the movement of the buffer slide column 412, realize the buffering and shock absorption of the mounting frame 41, and effectively reduce the impact on the battery assembly 5.

[0044] It should be noted that the electromagnetic buffer system 6 of the present application works on the principle of electromagnetism, and the structure is the existing automobile electromagnetic buffer structure. The buffering function is realized by controlling the current and magnetic field. The electromagnetic buffer system 6 is linked through a communication protocol, such as CAN bus protocol, to realize data interaction and sharing with the central control system of the automobile. In the process of driving the automobile, the electromagnetic buffer system 6 is coordinated and managed by the central control system. The central control system controls and schedules the electromagnetic buffer system 6 according to the overall operation state and demand of the automobile.

[0045] In addition, the electromagnetic buffer system 6 of the present application is equipped with attitude sensors such as acceleration sensors and collision sensors, which can obtain various dynamic data such as vehicle speed, acceleration and collision strength in the process of driving the automobile, and transmit these data to the electromagnetic buffer system 6 of the present application in real time. According to the driving state and potential impact risk of the automobile, the buffering parameters of the electromagnetic buffer system 6 can be adjusted in advance to improve the protection effect of the battery assembly 5.

[0046] Specifically, when the vehicle runs and bumps, the mounting frame 41 will have a vibration trend. At this time, the sensor data is detected by the attitude sensor, the buffer slide column 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 column 412 in real time, and transmits the signal to the central control system. The central control system analyzes the signal to determine the direction, intensity and duration of the vibration impact and other parameters, 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 size and direction of electromagnetic force, a reverse force is applied to the buffer slide column 412, so as to slow down the displacement speed and amplitude of the mounting frame 41, and realize the buffering protection of the battery assembly 5.

[0047] In another application scenario, when the vehicle tilts left and right in posture during forward movement, such as in off-road conditions, the battery assembly 5 on one side is closer to the ground, to avoid the increased risk of collision between the battery assembly 5 on that side and ground obstacles, the mounting frame 41 on the corresponding side can be lifted by the electromagnetic buffer system 6 on that side, so that the height of the mounting frame 41 is increased, thereby reducing the risk of collision of the battery assembly 5 under the tilted posture of the vehicle.

[0048] Please refer to Figures 5-11 , two groups of battery assemblies 5 are symmetrically fixed in the corresponding mounting frames 41, and the inclination angle of the battery cell 54 in the horizontal plane is 30°. The mounting frame 41 has an inclination angle in the vertical plane, which is optimized to better disperse the inertial force and support the battery assembly 5. Specifically, the battery assembly 5 is assembled by a plurality of equidistant and inclined battery cells 54, which are arranged in the opposite direction of the vehicle's forward movement. This arrangement can effectively disperse the frontal impact force of the battery cell 54 caused by the vehicle collision during vehicle operation by utilizing the inclination angle of the battery cell 54. At the same time, during the process of rapid acceleration and deceleration of the vehicle, the buffer resistance of the electromagnetic buffer system 6 on the mounting frame 41 can be reduced and then increased. 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 upward and deflect by the designed angle, converting the potential energy into the deflection kinetic energy of the mounting frame 41, thereby effectively reducing the mutual extrusion force between the battery cells 54 during the rapid speed change of the vehicle.

[0049] Both ends of the battery cell 54 are provided with end seats 52, one side of the end seat 52 is fixed with a connecting seat 53, the side away from the end seat 52 of the connecting seat 53 is provided with two groups of symmetrically arranged positioning holes 531, the end of the battery cell 54 is provided with a positioning pin 541 matched with the positioning hole 531, and the battery cell 54 is quickly assembled and installed between the two groups of end seats 52 through the cooperation of the positioning pin 541 and the positioning hole 531.

[0050] The side away from the battery cell 54 of the end seat 52 is rotatably connected with a ball 521, and the inner wall of the mounting frame 41 is provided with an assembly sliding groove 411 matched with the ball 521. The ball 521 rolls in the assembly sliding groove 411, making the installation of the battery assembly 5 in the mounting frame 41 more convenient and flexible, and further buffering external impact.

[0051] Please refer to Figures 7-10 , the adjacent battery cells 54 are also provided with a protective plate 51, the two ends of the protective plate 51 are provided with bolt holes 511, the protective plate 51 is fixed on the two groups 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 cell 54, and the other side is provided with a heat exchange capsule 512. The C-shaped groove 515 can fix and protect the battery cell 54, preventing displacement of the battery cell 54 in the battery assembly 5;

[0052] The heat exchange capsule 512 can effectively absorb and transfer the heat generated by the battery cell 54 during operation. The protective plate 51 is symmetrically provided with two sets of engaging hooks 513 on the upper and lower ends of one side, and two sets of engaging hook grooves 514 on the upper and lower ends of the other side. The engaging hook grooves 514 and the engaging hooks 513 of adjacent protective plates 51 are buckled, which makes the connection between the protective plates 51 more compact and stable, further enhancing the protection effect of the battery cell 54.

[0053] The heat exchange capsule 512 is filled with cooling liquid, which is perfluorohexanone cooling liquid with good fire extinguishing performance and electrical insulation performance. The heat exchange capsule 512 is provided with a pressure sensor and a temperature sensor inside. The input end and the output end of the heat exchange capsule 512 are provided with electromagnetic valves. The pressure sensor, the temperature sensor and the electromagnetic valves are electrically connected with the central control system of the vehicle.

[0054] Under normal application scenarios, after the multiple battery cells 54 are installed in the mounting frame 41, the pressure in each heat exchange capsule 512 is increased to a fixed design value through the electromagnetic valves, thereby expelling the adjacent battery cells 54 and fixing the relative position of the end seat 52 and the assembly sliding groove 411. On the one hand, the assembly positioning action of the multiple battery cells 54 is completed, and on the other hand, the expanded heat exchange capsule 512 forms a buffer space between the adjacent battery cells 54. In the heat dissipation scenario, the pressure sensor and the temperature sensor monitor the pressure and temperature of the cooling liquid in the protective plate 51 in real time. When the temperature rises, the electromagnetic valves open, the cooling liquid circulates and carries away the heat generated by the battery cell 54, achieving efficient heat dissipation.

[0055] Please refer to Figures 15-16In the vehicle collision scene, when the local battery cell 54 is hit, the pressure sensor in the heat exchange capsule 512 detects the sudden change of the pressure value of the heat exchange capsule 512, combined with the acceleration sensor and the collision sensor of the vehicle, the central control system determines the occurrence of the battery collision accident, at this time the heat exchange capsule 512 outside the collision place reduces the pressure through the electromagnetic valve, and the gap of the adjacent battery cell 54 is retracted, the space on both sides of the battery cell 54 is cleared, and the cooling liquid pressure is concentrated in the heat exchange capsule 512, the heat exchange capsule 512 is separated from the battery cell 54, and the end seat 52 on both sides of the battery cell 54 is in a free state, the subsequent impact will make the battery cell 54 deflect, on the one hand, the impact force is buffered, on the other hand, the impact port is downward, preventing the impact port from burning and causing personnel injury, when the battery cell 54 is hit and on fire, the heat will burn the adjacent and expanded heat exchange capsule 512, at this time the perfluorohexone cooling liquid in the heat exchange capsule 512 leaks and releases, the perfluorohexone cooling liquid can evaporate quickly, absorb a large amount of heat, and reduce the battery temperature, and its steam can isolate air and inhibit the combustion reaction, thereby effectively extinguishing the battery fire, and the perfluorohexone is environmentally friendly and will not cause harm to equipment and personnel, achieving the effect of fire extinguishing and protection after battery collision.

[0056] Please refer to Figure 2 and Figures 11-12 , the shell 1 includes an upper box body 11 and a lower sealing plate 12, both sides of the upper box body 11 are fixed with side anti-collision beams 111, and the top of the upper box body 11 is also provided with an electronic control unit 2; the upper box body 11 is provided with a buffer sliding groove 112 matched with a buffer sliding column 412; the side anti-collision beams 111 can enhance the lateral impact resistance of the shell 1 and protect the internal structure of the battery; the buffer sliding groove 112 is matched with the buffer sliding column 412 to further improve the buffering effect.

[0057] The lower sealing plate 12 is packaged at the bottom of the upper box body 11, the thickness of the middle part of the lower sealing plate 12 is greater than that of the two sides, and the bottom of the lower sealing plate 12 is also provided with a V-shaped reinforcing part 121; this structure design can effectively enhance the strength and stability of the bottom of the shell 1; when the bottom is hit, the V-shaped reinforcing part 121 will transfer the impact point of the obstacle to the two sides of the lower sealing plate 12, so that the upward deflection of the mounting frame 41 can more effectively protect the battery.

[0058] Please refer to Figure 6The middle shaft mounting seat 42 is provided with a plurality of riveting holes 421, and the middle shaft mounting seat 42 is fixed to the inner side of the upper box body 11 through the riveting holes 421. The top of the middle shaft mounting seat 42 is fixed with a connecting shaft 422, and the two groups of mounting frames 41 are rotatably connected to the connecting shaft 422. The two groups of mounting frames 41 are further clamped with a middle shaft buffer pad 44 on the opposite side. The middle shaft buffer pad 44 has an elastic force for driving the two groups of mounting frames 41 to move away from each other. When subjected to a lateral impact, the middle shaft buffer pad 44 can further buffer the interaction force between the mounting frames 41.

[0059] Please refer to Figures 4-5 The mounting frame 41 has a rhombic frame structure, and the four corners of the rhombic frame structure are rotatably connected. The top of the mounting frame 41 is further provided with an X-shaped rib 43. The four ends of the X-shaped rib 43 are rotatably connected to the four corners of the rhombic frame structure of the mounting frame 41. The structural strength of the X-shaped rib 43 is less than that of the mounting frame 41. This structural design enables the mounting frame 41 to have a certain elastic deformation capacity while ensuring the strength. In combination with the inclined placement mode of the battery assembly 5, the mounting frame 41 can better absorb impact energy.

[0060] The inner top of the upper box body 11 is further provided with a protective layer 3. 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. 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. A fitting gap 301 is arranged between the two groups of middle protective pads 32, which facilitates the installation of the middle shaft mounting seat 42 and the upper box body 11. The cross section of the middle protective pad 32 has a triangular structure. The middle protective pad 32 has an elastic force for driving the battery assembly 5 to move away from the upper box body 11, so as 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 vehicle advancement and has a slope for guiding the impact force to be distributed to both sides of the vehicle. The tail protective block 33 is arranged in the opposite direction of vehicle advancement. The head protective block 31 and the tail protective block 33 are both provided with a buffer layer. The protective layer 3 can effectively prevent the battery assembly 5 from being impacted and extruded from the front and rear directions and the upper direction of the vehicle.

[0061] The battery rack 4 with the buffering function is composed of the middle shaft mounting seat 42, the mounting frame 41, the buffer slide column 412 and the electromagnetic buffer system 6. When the storage battery is subjected to external impact or vibration, the battery rack 4 can effectively buffer and dampen, protect the battery assembly 5 and improve the impact resistance of the battery.

[0062] At the same time, the inclined arrangement of the battery cells 54 and the design of the protection plates 51 between the battery cells 54 can not only disperse the inertial force and reduce the extrusion between the battery cells, but also realize efficient heat dissipation through the cooling liquid in the protection plates and the heat exchange capsules, so as to ensure that the battery cells work at an appropriate temperature, prolong the service life of the battery, autonomously separate abnormal battery cells 54 in the impact scene, and actively perform fire extinguishing operation when the fire occurs, thereby further improving the impact resistance of the battery.

[0063] The above describes only the best mode of the present application in combination with the current actual demand, but the protection scope of the present application is not limited thereto.
