Description

Technical Field

[0001] The present invention relates to the technical field of battery boxes, and in particular to a high-strength shock-resistant new energy lithium battery box. Background Art

[0002] Electric vehicles are new energy vehicles that use electricity as a power source. Batteries are an indispensable part of electric vehicles. Batteries need to be installed on new energy vehicles through battery boxes. However, existing battery boxes will produce violent vibrations when new energy vehicles are driving on bumpy roads. This will reduce the service life of the batteries over a long period of time.

[0003] In the prior art, springs are used as buffer structures, and damping rods are used to absorb energy. The installation method is generally to install springs around the lithium battery. The springs are directly and vertically connected to the box body, and the springs are used for buffering. The buffering distance is the length of the spring. In order to obtain better buffering, the spring needs to be lengthened, which makes the box body much larger than the lithium battery pack to accommodate the longer spring. In addition, the damping structure can only be used for energy absorption and has a single function. Summary of the invention

[0007] In the above-mentioned high-strength shock-resistant new energy lithium battery box, each of the ratchet gears will only drive the ratchet gear to rotate as a whole when the spring is reset, and the ratchet inside the ratchet gear is engaged with the pawl, and the ratchet rotates under the push of the pawl.

[0008] In the above-mentioned high-strength shock-resistant new energy lithium battery box, the second connecting rod is fixedly connected to a movable shaft at one end away from the first connecting rod, and the second connecting rod is rotatably connected to the limit slider through the set movable shaft. The outer walls on both sides of the limit slider are fixedly connected to the limit block, and the inner walls on both sides of the limit slide groove are provided with side grooves, and the inner walls of the side grooves are slidably connected to the outer walls of the movable shaft and the limit block.

[0009] In the above-mentioned high-strength, shock-resistant new energy lithium battery box, the inner wall of the transmission structure is rotatably connected with a large gear and a small gear, the outer wall of the large gear is meshed with the outer wall of the small gear, and the small gear, small gear, ratchet gear, and counterweight rotor are all fixedly connected with pulleys at the center. A first belt and a second belt are also arranged inside the transmission structure. The large gear is rotatably connected with the ratchet gear through the set pulley and the first belt, and the small gear is transmission-connected with the counterweight rotor through the set pulley and the second belt.

[0010] In the above-mentioned high-strength shock-resistant new energy lithium battery box, a first bracket is fixedly connected to the bottom of the transmission structure, and the transmission structure is fixedly connected to the mouth-shaped fixed frame through the first bracket.

[0013] In the above-mentioned high-strength shock-resistant new energy lithium battery box, the lower anti-collision pad is located directly below the lithium battery module, and the upper anti-collision pad is located directly above the lithium battery module.

[0014] Compared with the existing technology, the advantages of this high-strength earthquake-resistant new energy lithium battery box are:

[0015] 1. The buffer structure is set up, and when the present invention vibrates up and down, the buffer structure will be compressed. The positions of the fixed shaft and the mouth-shaped fixed frame are fixed, and the base plate is close to the lithium battery module. The first connecting rod will rotate outward along the fixed shaft under the limit of the limit plate, and the second connecting rod will rotate along the end of the first connecting rod, so that the other end of the first connecting rod pushes the limit slider, and the spring is compressed by the limit slider. Due to the use of the connecting rod structure of the first connecting rod and the second connecting rod, when the buffer structure is compressed, the second connecting rod can push the limit slider to slide a longer distance along the limit sliding groove, and the spring is arranged on the side of the lithium battery module, not directly installed on the top or bottom of the lithium battery module. There is enough space on the side to install a longer spring, so that the buffer effect can be improved, and the overall device is small and compact, and the size difference with the lithium battery module is not large;

[0016] 2. When the energy-absorbing structure limit slider is used to compress the spring, the rack outside the limit slider will push the outer ring of the ratchet gear to rotate, and the ratchet inside the ratchet gear will not engage with the ratchet. When the spring is reset, the rack outside the limit slider will drive the ratchet gear to rotate as a whole. Under the transmission of the transmission structure, the heavier counterweight rotor will rotate, and the kinetic energy of the spring reset will be absorbed by the rotation of the counterweight rotor, slowing down the reset speed, so that the lithium battery module is more stable during oscillation. At the same time, the counterweight rotor will drive the fan to rotate when it rotates, and the fan will promote the circulation of air inside the high-strength box to promote the heat dissipation of the high-strength box. In addition, there is inertia after the counterweight rotor rotates. After the spring is completely reset, the counterweight rotor will rotate under its inertia. With the setting of the ratchet gear, the inner ring of the ratchet gear continues to rotate, and the ratchet will not engage with the ratchet, so that the counterweight rotor can still continue to rotate without restriction, that is, the fan can rotate for a longer time to achieve a better heat dissipation effect. The wind resistance when the fan rotates can also increase the resistance when the spring is reset, so that the high-strength box is more stable during oscillation.

[0017] 3. Through the fans set up, when the bottom mouth-shaped fixed frame is reset, the two fans in front of the lithium battery module will blow air out of the high-strength box, and when the top mouth-shaped fixed frame is reset, the two fans behind the lithium battery module will suck air into the high-strength box, which can promote the circulation of air inside the high-strength box and promote the heat dissipation of the lithium battery module;

[0018] 4. By setting the rubber strip, upper anti-collision pad and lower anti-collision pad, during severe vibration, the rubber strip with smaller deformation can be compressed by the limit slider to further buffer the spring and prevent it from being damaged due to excessive compression. The upper anti-collision pad and the lower anti-collision pad can prevent the lithium battery module from directly colliding with the high-strength box. BRIEF DESCRIPTION OF THE DRAWINGS

The front energy absorbing structure 7 is connected to the bottom mouth-shaped fixing frame 3, and the rear energy absorbing structure 7 is connected to the top mouth-shaped fixing frame 3. When the present invention is in use, through the buffer structure 5, when the present invention vibrates up and down, the lithium battery module 2 will squeeze the buffer structure 5, and the two springs 14 are compressed by the expansion of the buffer structure 5. The spring 14 plays a buffering role, and the energy absorbing structure 7 absorbs energy when the spring 14 is reset;As a preferred technical solution of the present invention, the buffer structure 5 includes a fixed shaft 9 and a base plate 8, the fixed shaft 9 is fixedly connected to the outer wall of the lithium battery module 2, both ends of the fixed shaft 9 are rotatably connected to the first connecting rod 10, and each end of the first connecting rod 10 away from the fixed shaft 9 is rotatably connected to the second connecting rod 12 through a rotating shaft, and the top of the base plate 8 is fixedly connected to two limit plates 11, and a horizontally arranged waist-shaped hole is opened on the limit plate 11. The inner wall of the waist-shaped hole is slidably connected to the rotating shaft at the end of the second connecting rod 12, and the end of the second connecting rod 12 away from the first connecting rod 10 is rotatably connected to the limit plate 11. Slider 13, the outer wall of the limit slider 13 is slidably connected to the inner wall of the limit slide groove 4, one side of the limit slider 13 is fixedly connected to the end of the spring 14, the top of the limit slider 13 is fixedly connected with a rack 15, and the interior of the mouth-shaped fixed frame 3 is also provided with a movable groove 16 for the rack 15 to move, that is, when the lithium battery module 2 moves upward or downward during vibration, it will compress the buffer structure 5, the fixed shaft 9 and the mouth-shaped fixed frame 3 are fixed, the base plate 8 is close to the lithium battery module 2, and the first connecting rod 10 will rotate outward along the fixed shaft 9 under the limit of the limit plate 11. The second connecting rod 12 will rotate along the end of the first connecting rod 10, so that the other end of the first connecting rod 10 pushes the limit slider 13, and the limit slider 13 compresses the spring 14. Due to the connecting rod structure of the first connecting rod 10 and the second connecting rod 12, when the buffer structure 5 is compressed, the second connecting rod 12 can push the limit slider 13 to slide a longer distance along the limit slide groove 4, and the spring 14 is arranged on the side of the lithium battery module 2, not directly installed on the top or bottom of the lithium battery module 2. There is enough space on the side to install a longer spring 14 to improve the buffer. The effect is achieved, and when the buffer structure 5 is compressed as a whole and the limit slider 13 compresses the spring 14, the rack 15 outside the limit slider 13 will push the outer ring of the ratchet gear 17 to rotate, and the ratchet pawl inside the ratchet gear 17 will not be engaged with the ratchet. When the spring 14 is reset, the rack 15 outside the limit slider 13 will drive the ratchet gear 17 to rotate as a whole, and through the transmission of the transmission structure 18, the energy absorption structure 7 is driven to operate. The kinetic energy of the spring 14 when it is reset is absorbed by the operation of the energy absorption structure 7, and the speed of reset is slowed down, so that the lithium battery module 2 is more stable during oscillation;As a preferred technical solution of the present invention, the energy absorption structure 7 includes a ratchet gear 17, a transmission structure 18, a counterweight rotor 19 and a fan 20. The ratchet gear 17, the transmission structure 18 and the counterweight rotor 19 are all installed on the outside of the mouth-shaped fixed frame 3. The ratchet gear 17 is meshed with the rack 15. The ratchet gear 17 is connected to the counterweight rotor 19 through the transmission structure 18. The central axis of the counterweight rotor 19 is fixedly connected to the center of the fan 20. The front and rear ends of the high-strength box 1 are respectively provided with an exhaust port 21 and an air inlet 22. Each The ratchet gear 17 is driven to rotate as a whole only when the spring 14 is reset, and the rack 15 on the spring 14 engages with the ratchet pawl inside the ratchet gear 17, and the ratchet rotates under the push of the pawl. At the same time, the fan blades on the fan 20 make adaptive adjustments. Overall, when the bottom mouth-shaped fixing frame 3 is reset, the two fans 20 in front of the lithium battery module 2 will blow air out of the high-strength box 1, and when the top mouth-shaped fixing frame 3 is reset, the two fans 20 behind the lithium battery module 2 will suck air into the high-strength box 1, In terms of the structure, the transmission structure 18 plays a transmission role. When the spring 14 is reset, it will push the rack 15 to drive the ratchet gear 17 to rotate as a whole. Under the transmission of the transmission structure 18, the heavier counterweight rotor 19 is rotated. The rotation of the counterweight rotor 19 absorbs the kinetic energy of the spring 14 when it is reset, slowing down the reset speed, so that the lithium battery module 2 is more stable during the oscillation. At the same time, when the counterweight rotor 19 rotates, it will drive the fan 20 to rotate. The fan 20 will promote the circulation of air inside the high-strength box 1 to promote the high-strength The heat dissipation of the box body 1, and the counterweight rotor 19 has inertia after rotation. After the spring 14 is completely reset, the counterweight rotor 19 will rotate under its inertia, and the setting of the ratchet gear 17, the inner ring of the ratchet gear 17 continues to rotate, and the ratchet will not engage with the pawl, so that the counterweight rotor 19 can still continue to rotate without restriction, that is, the fan 20 can rotate for a longer time to achieve a better heat dissipation effect. The wind resistance of the fan 20 during rotation can also increase the resistance of the spring 14 during reset, making the high-strength box body 1 more stable during oscillation. ;

[0033] In order to limit the limit slider 13 and allow the limit slider 13 to only move linearly along the limit slide groove 4, the present invention adopts the following technical means: the end of the second connecting rod 12 away from the first connecting rod 10 is fixedly connected with a movable shaft 23, and the second connecting rod 12 is rotatably connected to the limit slider 13 through the set movable shaft 23. The outer walls on both sides of the limit slider 13 are fixedly connected with the limit blocks 24, and the inner walls on both sides of the limit slide groove 4 are provided with side grooves 25. The inner walls of the side grooves 25 are slidably connected to the outer walls of the movable shaft 23 and the limit blocks 24.

[0034] In order to increase the damping when the spring 14 is reset and allow the counterweight rotor 19 to rotate more circles or rotate faster when reset, the present invention adopts the following technical solution: the inner wall of the transmission structure 18 is rotatably connected with a large gear 26 and a small gear 27, the outer wall of the large gear 26 is meshed with the outer wall of the small gear 27, and the center of the small gear 27, the small gear 27, the ratchet gear 17, and the counterweight rotor 19 are all fixedly connected with a pulley 28. A first belt 29 and a second belt 30 are also provided inside the transmission structure 18. The large gear 26 is rotatably connected to the ratchet gear 17 through the provided pulley 28 and the first belt 29, and the small gear 27 is transmission-connected to the counterweight rotor 19 through the provided pulley 28 and the second belt 30. The ratchet gear 17 drives the large gear 26 to rotate, and the large gear 26 drives the small gear 27 meshing therewith to rotate more circles, and the counterweight rotor 19 is driven by the small gear 27 to rotate.

[0035] Among them, the bottom of the transmission structure 18 is fixedly connected with a first bracket 31, and the transmission structure 18 is fixedly connected to the mouth-shaped fixed frame 3 through the set first bracket 31. The counterweight rotor 19 is rotatably connected with a second bracket 32 ​​at the rotating shaft, and the counterweight rotor 19 is fixedly connected to the mouth-shaped fixed frame 3 through the set second bracket 32.

[0036] In order to prevent the limit slider 13 from colliding with the mouth-shaped fixed frame 3 during severe vibration, a rubber strip 36 is installed on the inner wall of the limit slide groove 4 away from the spring 14, and a mounting hole for installing the rubber strip 36 is opened on the inner wall of the limit slide groove 4 close to the spring 14. One end of the rubber strip 36 extends to the inside of the spring 14. The setting of the rubber strip 36 plays a role in protecting the spring 14. During severe vibration, the rubber strip 36 with a smaller deformation amount is compressed by the limit slider 13, which has a further buffering effect and prevents the spring 14 from being damaged due to excessive compression.

[0037] In order to prevent the lithium battery module 2 from directly colliding with the high-strength box body 1, two pressure blocks 33 cooperating with the base plate 8 are fixedly connected inside the box cover 6, and an upper anti-collision pad 34 is fixedly connected to the bottom of the pressure block 33, and a lower anti-collision pad 35 is fixedly connected to the bottom of the inner wall of the high-strength box body 1, thereby protecting the high-strength box body 1, wherein the lower anti-collision pad 35 is located directly below the lithium battery module 2, and the upper anti-collision pad 34 is located directly above the lithium battery module 2.

[0038] The working principle of the present invention is explained clearly and completely as follows: when in use, the lithium battery module 2 is placed inside the high-strength box 1, and then the box cover 6 is closed. The pressing block 33 on the box cover 6 will be connected to the substrate 8. The lithium battery module 2 is located in the middle of the high-strength box 1 under the support of the buffer structure 5. When the present invention vibrates up and down, the buffer structure 5 will be pressed. The position of the fixed shaft 9 and the mouth-shaped fixed frame 3 is fixed. The substrate 8 is close to the lithium battery module 2. The first connecting rod 10 will rotate outward along the fixed shaft 9 under the limitation of the limiting plate 11, and the second connecting rod 12 will rotate along the end of the first connecting rod 10, so that the other end of the first connecting rod 10 pushes the limiting slider 13, and the spring 14 is compressed by the limiting slider 13. The connecting rod structure of the second connecting rod 12 can push the limiting slider 13 to slide a longer distance along the limiting slide groove 4 when the buffer structure 5 is under pressure, and the spring 14 is arranged on the side of the lithium battery module 2, and is not directly installed on the top or bottom of the lithium battery module 2. There is enough space on the side to install a longer spring 14 to improve the buffering effect. Moreover, when the buffer structure 5 is compressed as a whole and the limiting slider 13 compresses the spring 14, the rack 15 outside the limiting slider 13 will push the outer ring of the ratchet gear 17 to rotate, and the ratchet pawl inside the ratchet gear 17 will not be engaged with the ratchet wheel. When the spring 14 is reset, the rack 15 outside the limiting slider 13 will drive the ratchet gear 17 to rotate as a whole. Under the transmission of the transmission structure 18, the longer The heavy counterweight rotor 19 rotates, and the rotation of the counterweight rotor 19 absorbs the kinetic energy of the spring 14 when it is reset, slowing down the reset speed, so that the lithium battery module 2 is more stable during the oscillation. At the same time, the counterweight rotor 19 will drive the fan 20 to rotate when it rotates, and the fan 20 will promote the circulation of air inside the high-strength box 1 to promote the heat dissipation of the high-strength box 1. Moreover, there is inertia after the counterweight rotor 19 rotates. After the spring 14 is completely reset, the counterweight rotor 19 will rotate under its inertia. The setting of the ratchet gear 17, the inner ring of the ratchet gear 17 continues to rotate, and the ratchet will not engage with the pawl, so that the counterweight rotor 19 can still continue to rotate without restriction, that is, the fan 20 can rotate for a longer time to achieve better heat dissipation. The wind resistance when the fan 20 rotates can also increase the resistance when the spring 14 is reset, so that the high-strength box 1 is more stable during the oscillation, and when the bottom mouth-shaped fixing frame 3 is reset, the two fans 20 in front of the lithium battery module 2 will blow air out of the high-strength box 1, and when the top mouth-shaped fixing frame 3 is reset, the two fans 20 behind the lithium battery module 2 will suck air into the high-strength box 1, which can promote the circulation of air inside the high-strength box 1 and promote the heat dissipation of the lithium battery module 2. The device is provided with a rubber strip 36, an upper anti-collision pad 34 and a lower anti-collision pad 35. During severe oscillation, the rubber strip 36 with a smaller deformation amount is compressed by the limit slider 13, which has a further buffering effect to prevent the spring 14 from being damaged due to excessive compression.The upper anti-collision pad 34 and the lower anti-collision pad 35 can prevent the lithium battery module 2 from directly colliding with the high-strength box 1.

[0039] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
