Technical Field

[0001] The present invention relates to the technical field of automobile batteries, and in particular to a new energy automobile battery anti-collision device. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies and new structures. New energy vehicles include four major types: hybrid electric vehicles (HEV), pure electric vehicles (BEV, including solar vehicles), fuel cell electric vehicles (FCEV), and other new energy vehicles (such as supercapacitors, flywheels and other high-efficiency energy storage devices).

[0003] However, when the existing new energy vehicle batteries are in use, they are easily deformed due to external impacts, which may cause leakage of the battery electrolyte, thereby causing the remaining batteries to short-circuit and then burn the vehicle. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the present invention provides a new energy vehicle battery anti-collision device, which solves the problems raised in the above background technology.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a new energy vehicle battery anti-collision device, comprising a base, an installation frame for installing the battery arranged on the top of the base, an anti-collision mechanism is arranged on the outer side of the installation frame, the anti-collision mechanism comprises a first splicing block, a second splicing block, and two fixed frames, grooves are opened on both sides of the first splicing block, and protrusions matching the grooves are fixedly connected at both ends of the second splicing block. The two fixed frames are symmetrically arranged on both sides of the installation frame and fixedly connected to the base, and protrusions matching the grooves are fixedly connected at both ends of the fixed frames. A plurality of staggered first splicing blocks and second splicing blocks are spliced ​​between the two fixed frames, so that the two fixed frames, the first splicing block and the second splicing block form an anti-collision frame surrounding the installation frame, and the anti-collision frame deforms after being subjected to the impact force to absorb the impact force.

[0008] Preferably, a fixed block is arranged between the two fixed frames, the bottom of the fixed block is fixedly connected to the base, and protrusions matching the grooves are fixedly connected to both sides of the fixed block, and the first splicing block and the second splicing block are staggered between the fixed block and the fixed frame.

[0009] Preferably, fixing components for fixation are provided on both the first splicing block and the second splicing block. The fixing component includes a vertical rod, a screw rod, a knob, and a rotating ring. Through holes penetrating the upper and lower surfaces are formed on the first splicing block and the second splicing block. The vertical rod is rotatably fitted in the through hole. A rotating ring is fixedly connected to the vertical rod. A screw rod is fixedly connected to the bottom end of the vertical rod. A knob is fixedly connected to the top end of the vertical rod. A threaded hole matching the screw rod is formed on the base.

[0010] Preferably, the first splicing block and the second splicing block have the same length, and the length of the first splicing block is greater than the length of the fixing block.

[0011] Preferably, the base includes a top mounting plate, a bottom mounting plate, and a housing. The top mounting plate is arranged above the bottom mounting plate, and the threaded hole is formed on the top mounting plate. The outer sides of the top mounting plate and the bottom mounting plate are fixedly connected to the housing. A direct impact prevention mechanism for preventing the first splicing block and the second splicing block that may be broken by impact from directly hitting the mounting frame is arranged between the top mounting plate and the bottom mounting plate.

[0012] Preferably, the direct impact prevention mechanism includes a compressed gas tank, a connecting air pipe, an air delivery channel, a ventilation hole, and a storage air chamber. The cross-section of the air delivery channel is arranged in a U shape, and the air delivery channel completely covers the bottom of all the threaded holes. A storage air chamber is formed inside the straight rod. A ventilation hole is formed in the screw rod, and the storage air chamber is communicated with the inside of the air delivery channel through the ventilation hole. The outlet of the compressed gas tank is fixedly connected to the connecting air pipe. The end of the connecting air pipe far from the compressed gas tank is fixedly connected to the air delivery channel, so that the compressed gas tank is communicated with the inside of the air delivery channel. The compressed gas tank inputs compressed gas into all the storage air chambers through the connecting air pipe and the air delivery channel. When the vertical rod of the splicing block breaks, the compressed gas in the storage air chamber sprays downward, and at the same time, the gas in the air delivery channel sprays upward through the broken opening, so that the splicing block receives an upward force and the splicing block flies upward and will not directly hit the mounting frame.

[0013] Preferably, a top cover is fixedly connected to the top of the mounting frame. The outer side surface of the top cover is arranged as an inclined surface inclined inward. When the flying-up splicing block flies upward, it will collide with the outer inclined surface of the top cover and then move along the inclined surface to above the top cover.

[0016] Preferably, the gas delivery channel is arranged in an H shape, and the compressed gas tank is arranged in an inner recess of the gas delivery channel.

[0017] (III) Beneficial effects

[0018] The present invention provides a new energy vehicle battery anti-collision device, which has the following beneficial effects:

[0019] 1. The new energy vehicle battery anti-collision device forms an anti-collision frame that surrounds the installation frame through a fixed frame, a first splicing block and a second splicing block. The anti-collision frame deforms after being hit to absorb the impact force, so that the anti-collision mechanism protects the battery and reduces the probability of battery fire. Moreover, through the setting of the fixed component, during installation, it is only necessary to plug the splicing block through the groove and the plug-in block, and then screw the screw into the screw hole. The installation and replacement are very convenient and quick, and it is easy to repair and install.

[0020] 2. The battery anti-collision device for new energy vehicles is provided with an anti-direct collision mechanism. When a heavy collision causes the vertical rod inside the splicing block to break under the impact, causing the entire splicing block to fly out to the inside, at this time, the vertical rod of the splicing block breaks, and the compressed gas in the storage gas chamber is ejected downward, and at the same time, the gas in the gas transmission channel is ejected upward through the broken opening, so that the splicing block is subjected to an upward force, and the splicing block flies upward and will not directly hit the installation frame. At the same time, it cooperates with the top cover. When the splicing block flying upward flies upward, it will collide with the outer inclined surface of the top cover and then move along the inclined surface to the top of the top cover, thereby preventing the splicing block from directly impacting the installation frame to the greatest extent, thereby ensuring the safety of the battery inside the installation frame.

[0021] 3. The new energy vehicle battery anti-collision device can reduce the weight of the splicing blocks without reducing the overall strength through the hollow splicing blocks and the reinforcement ribs. When impacted, it can produce deformation to absorb the impact force well, and can also ensure that it can fly upward under the impact of compressed gas. The gas transmission channel is set in an H shape, and the compressed gas tank is set in the inner concave part of the gas transmission channel. The outer shell can be removed to directly install or replace the compressed gas tank from the side, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0035] The embodiment of the present invention provides a new energy vehicle battery anti-collision device, such as Figure 1-11 As shown, it includes a base 1, an installation frame 2 for installing a battery arranged on the top of the base 1, an anti-collision mechanism is arranged on the outer side of the installation frame 2, and the anti-collision mechanism includes a first splicing block 6, a second splicing block 7, and two fixed frames 4. Grooves are opened on both sides of the first splicing block 6, and both ends of the second splicing block 7 are fixedly connected with protrusions matching the grooves. The two fixed frames 4 are symmetrically arranged on both sides of the installation frame 2 and fixedly connected to the base 1. Both ends of the fixed frames 4 are fixedly connected with protrusions matching the grooves. A plurality of staggered first splicing blocks 6 and second splicing blocks 7 are spliced ​​between the two fixed frames 4, so that the two fixed frames 4, the first splicing block 6 and the second splicing block 7 form an anti-collision frame surrounding the installation frame 2, and the anti-collision frame is deformed after being subjected to the impact force to absorb the impact force.

[0036] A fixed block 5 is arranged between the two fixed frames 4, the bottom of the fixed block 5 is fixedly connected to the base 1, and protrusions matching the grooves are fixedly connected to both sides of the fixed block 5, and the first splicing block 6 and the second splicing block 7 are staggered between the fixed block 5 and the fixed frame 4.

[0037] The first splicing block 6 and the second splicing block 7 are both provided with a fixing assembly for fixing, and the fixing assembly includes a vertical rod 19, a screw rod 18, a knob 17, and a rotating ring 16. The first splicing block 6 and the second splicing block 7 are provided with a through hole penetrating the upper and lower surfaces, and the vertical rod 19 is rotatably fitted in the through hole. The vertical rod 19 is fixedly connected to the rotating ring 16, the bottom end of the vertical rod 19 is fixedly connected to the screw rod 18, the top end of the vertical rod 19 is fixedly connected to the knob 17, and the base 1 is provided with a screw hole 10 matching the screw rod 18.

[0038] The first splicing block 6 and the second splicing block 7 have the same length, and the length of the first splicing block 6 is greater than the length of the fixing block 5 .

[0039] An anti-collision frame surrounding the installation frame 2 is formed by fixing the frame 4, the first splicing block 6 and the second splicing block 7. The anti-collision frame is deformed after being hit to absorb the impact force, so that the anti-collision mechanism protects the battery and reduces the probability of battery fire. In addition, through the setting of the fixed component, during installation, it is only necessary to plug the splicing block through the groove and the plug-in block, and then screw the screw 18 into the screw hole 10. The installation and replacement is very convenient and quick, and it is easy to carry out maintenance and installation.

[0040] The base 1 includes a top mounting plate 9, a bottom mounting plate 12, and an outer shell 8. The top mounting plate 9 is arranged above the bottom mounting plate 12, and a screw hole 10 is opened on the top mounting plate 9. The outer sides of the top mounting plate 9 and the bottom mounting plate 12 are fixedly connected to the outer shell 8. An anti-direct impact mechanism is arranged between the top mounting plate 9 and the bottom mounting plate 12 to prevent the first splicing block 6 and the second splicing block 7 that will be broken by impact from directly colliding with the mounting frame 2.

[0041] The direct impact prevention mechanism includes a compressed gas tank 14, a connecting air pipe 13, an air delivery channel 11, a ventilation hole 20, and a storage gas chamber 21. The cross-section of the air delivery channel 11 is set in a U shape, and the air delivery channel 11 completely covers the bottom of all the screw holes 10. A storage gas chamber 21 is provided inside the straight rod. A ventilation hole 20 is provided inside the screw 18, and the storage gas chamber 21 is communicated with the inside of the air delivery channel 11 through the ventilation hole 20. A connecting air pipe 13 is fixedly connected to the air outlet of the compressed gas tank 14, and one end of the connecting air pipe 13 away from the compressed gas tank 14 is fixedly connected to the air delivery channel 11, so that the compressed gas tank 14 is communicated with the inside of the air delivery channel 11. The compressed gas tank 14 inputs compressed gas into all the storage gas chambers 21 through the connecting air pipe 13 and the air delivery channel 11. When the vertical rod 19 of the splicing block breaks, the compressed gas in the storage gas chamber 21 sprays downward, and at the same time, the gas in the air delivery channel 11 sprays upward through the broken opening, so that the splicing block receives an upward force and the splicing block flies upward without directly hitting the mounting frame 2.

[0042] Through the setting of the direct impact prevention mechanism, when a relatively heavy impact causes the vertical rod 19 inside the splicing block to break under the impact and the whole splicing block flies inward, at this time, the vertical rod 19 of the splicing block breaks, the compressed gas in the storage gas chamber 21 sprays downward, and at the same time, the gas in the air delivery channel 11 sprays upward through the broken opening, so that the splicing block receives an upward force and the splicing block flies upward without directly hitting the mounting frame 2. At the same time, it cooperates with the top cover 3. When the upward flying splicing block flies upward, it will collide with the outer inclined surface of the top cover 3 and move along the inclined surface to the upper part of the top cover 3, so as to maximize the situation that the splicing block does not directly impact on the mounting frame 2 and ensure the safety of the battery inside the mounting frame 2.

[0043] A top cover 3 is fixedly connected to the top of the mounting frame 2, and the outer side surface of the top cover 3 is set as an inclined surface inclined inward. When the upward flying splicing block flies upward, it will collide with the outer inclined surface of the top cover 3 and move along the inclined surface to the upper part of the top cover 3.

[0044] Both the first splicing block 6 and the second splicing block 7 are hollow, and reinforcing ribs 15 are fixedly connected inside the first splicing block 6 and the second splicing block 7.

[0045] The air delivery channel 11 is set in a rectangle, and the compressed gas tank 14 is arranged inside the rectangle.

[0046] By setting the hollow splicing blocks and reinforcing ribs 15, the weight of the splicing blocks can be reduced without reducing the overall strength. When impacted, the blocks can be deformed to absorb the impact force well, and can also fly upward under the impact of compressed gas. The gas transmission channel 11 is set to an H shape, and the compressed gas tank 14 is set in the inner recess of the gas transmission channel 11. The outer shell 8 can be removed and the compressed gas tank 14 can be directly installed or replaced from the side, which is more convenient to use.

[0047] The gas delivery channel 11 is configured to be H-shaped, and the compressed gas tank 14 is disposed in a recessed portion of the gas delivery channel 11 .

[0048] Working principle: An anti-collision frame surrounding the installation frame 2 is formed by fixing the frame 4, the first splicing block 6 and the second splicing block 7. The anti-collision frame deforms after being hit to absorb the impact force, so that the anti-collision mechanism protects the battery and reduces the probability of battery fire. In addition, through the setting of the fixed component, during installation, it is only necessary to plug the splicing block through the groove and the plug-in block, and then screw the screw 18 into the screw hole 10. The installation and replacement is very convenient and quick, and it is easy to carry out maintenance and installation.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
