[0015] The present invention has the following advantages: The present invention provides a battery support and fixing device for automobile parts through improvement, which has the following improvements compared with similar devices: The battery support and fixing device for automobile parts described in the present invention combines temperature and smoke sensors with a GSM module to provide real-time monitoring and remote alarms, ensuring timely response to abnormal situations. The impact triggers the gas generator to release high-pressure gas → the drive bolt rotates in the opposite direction to release the box fixation → the ceramic cutter cuts the high-voltage cable, achieving rapid physical separation of the box and the vehicle body. After separation, the drive wheel driven by the torsion spring cooperates with the hot melt mechanism of the fuse to automatically move the box out of the dangerous area of the chassis.

[0016] The battery support and fixing device for automobile parts disclosed in the present invention is designed such that when the battery box is separated from the chassis and the temperature of the battery box rises, the fuse breaks due to the heat, releasing the drive wheel. The torsion spring drives the contact wheel to rotate, pushing the battery box away from the vehicle chassis, thereby preventing the fire from spreading to the entire vehicle. The fire blanket automatically deploys: When the box is separated from the chassis, the drive wheel pulls the fire blanket through the steel wire to slide and deploy in the groove. The permanent magnet and the adsorption magnet are magnetically closed, driving the fire blanket to wrap the front and rear ends and the top of the box, forming a high-temperature resistant isolation layer to prevent flames from leaking out and reduce the contact time with external oxygen.

[0017] The nitrogen in the gas storage tank expands due to heat, pushing the rubber membrane to squeeze the fire blanket, strengthening its sealing with the groove and further isolating it from external oxygen.

[0018] The present invention discloses a battery support and fixing device for automotive parts. When the vehicle is driving, the airflow under the chassis contacts the heat-conducting frame through the guide cavity of the guide frame, and the air flow removes heat. The heat-absorbing medium in the heat-conducting frame absorbs the heat of the battery, thereby improving the heat dissipation efficiency. When the vehicle is bumpy or the chassis is hit, the spring damper of the receiving assembly drives the heat-conducting frame to move up and down, promoting air circulation in the box, forming an active heat dissipation airflow, avoiding the extraction of external air into the box for heat exchange, and reducing the intrusion of external impurities. When the chassis is hit, the contact plate absorbs the impact force through the second spring damper, while pushing the thermal frame to compress air for heat exchange, taking into account both mechanical protection and heat dissipation needs.

[0019] The present invention provides a battery support and fixing device for automotive parts. An external water pipe conveys high-pressure water into a threaded pipe, which is then conveyed to an upper conveying trough through the threaded pipe, and then sprayed to the surrounding areas of the box body 1 through a transmission nozzle in the upper conveying trough. Since the cooling effect of the battery increases with the increase in water consumption, consuming 20.8 g·W–1·h–1 of water can prevent the spread of thermal runaway. The more nozzles there are, the greater the spray flow rate and the better the fire extinguishing effect, thereby improving the fire extinguishing effect on the battery.

[0025] See also Figures 1 to 12The present invention provides a battery support and fixing device for automotive parts, including a box body 1, which is used to be installed in the battery installation area at the bottom of a new energy vehicle, and the battery pack for storing electricity in the new energy vehicle can be installed in the box body 1; a box cover 2 is provided on the top of the box body 1, and a threaded hole that matches the bolt 37 is provided on the top of the box cover 2. A driving component 3 is provided in the box body 1, and a receiving component 4 is fixedly connected to the bottom of the box body 1. The receiving component 4 can generate power to drive the drainage frame 47 in the receiving component 4 to move when the vehicle body shakes up and down due to the bumps of the vehicle driving on the road and the vehicle chassis is hit, and the air in the box body 1 is drawn into the upper end of the receiving frame 41 for heat exchange, and then transported to the box body 1 through the second one-way valve 43, completing an air backflow, avoiding cooling by drawing external air into the box body 1.

[0026] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 The inner wall of the box body 1 is equidistantly provided with multiple groups of temperature sensors 11, and the temperature inside the box body 1 is detected by the temperature sensor 11. The inner wall of the box body 1 is fixedly connected with a smoke sensor 12, and a groove 13 is embedded in the top of the box body 1; The top of the box body 1 is fixedly connected to an adsorption magnet 14, and a bottom rod 15 is slidably connected in the groove 13. A plurality of groups of balls are movably provided in the bottom area of the bottom rod 15, and the bottom rod 15 is slidably inserted into the outer cylinder 16. A return spring 17 is fixedly connected in the outer cylinder 16, and the other end of the return spring 17 is fixedly connected to the bottom of the bottom rod 15. The two groups of outer cylinders 16 are connected and fixed as a whole through a permanent magnet 18. The side wall of the groove 13 is fixedly connected to one end of the fire blanket 19, and the other end of the fire blanket 19 is fixedly connected to the outer cylinder 16 and the side wall of the permanent magnet 18; when the top of the outer cylinder 16 is not squeezed by external force, that is, when the box body 1 is separated from the bottom area of the new energy vehicle chassis, the height of the top of the outer cylinder 16 and the permanent magnet 18 is higher than the top of the box body 1 and the box cover 2, which makes it convenient for the outer cylinder 16 to pull the fire blanket 19 to slide in the upper end area of the box cover 2 and wrap the top of the box 1 and the box cover 2 inside; A main control board and a battery are provided in the box 1, and the main control board is connected to the GSM module, the smoke sensor 12, and the temperature sensor 11; when the smoke sensor 12 detects smoke and the temperature sensor 11 detects that the temperature is too high, the GSM module calls the user and sends a reminder message.

[0027] Reference Figure 3A threaded pipe 1a is embedded in the side wall of the housing 1, and a one-way valve is installed in the area connecting the threaded pipe 1a to the upper conveying trough 33. The one-way valve is used to connect the threaded pipe 1a to the upper conveying trough 33. In some cases, an external water pipe is connected to the threaded pipe 1a, and the external water pipe also delivers high-pressure water into the threaded pipe 1a. The water is then transported to the upper conveying trough 33 through the threaded pipe 1a, and then sprayed to the surrounding area of the housing 1 through the transmission nozzle 333 in the upper conveying trough 33. Since the cooling effect of the battery increases with the increase in water consumption, consuming 20.8g·W–1·h–1 of water can prevent the spread of thermal runaway. The more nozzles there are, the greater the spray flow rate or the earlier the spray start time, which improves the fire extinguishing effect on the battery.

[0028] Reference Figures 3 to 8 The bottom side wall of the bottom rod 15 is fixedly connected with a steel wire 110, one end of the steel wire 110 is wound on the driving wheel 112, and an embedding groove 111 is embedded in the box body 1. The driving wheel 112 is rotatably connected in the embedding groove 111 through a torsion spring. The center of the driving wheel 112 is fixedly connected to the contact wheel 113, and the contact wheel 113 is rotatably connected to the embedding groove 111. The bottom area of the contact wheel 113 is lower than the bottom of the box body 1, and the front and rear ends of the other end of the box body 1 are rotatably connected with another two groups of contact wheels 113, which is convenient for supporting the four corners of the box body 1. Multiple groups of fuses 114 are fixedly connected to the side wall of the driving wheel 112, and the other end of the fuse 114 is fixedly connected to the side wall of the embedding groove 111; when the fuse 114 is heated, the fuse 114 will break and lose the restriction on the driving wheel 112.

[0029] When the box body 1 is separated from the vehicle chassis area, the fuse 114 is affected by the temperature and breaks, and the fuse 114 loses its restriction on the driving wheel 112. The driving wheel 112 drives the contact wheel 113 to rotate through the torsion spring, and the contact wheel 113 can drive the box body 1 to move outward and away from the vehicle chassis area; The driving wheel 112 reels the steel wire 110, causing the steel wire 110 to pull the bottom rod 15 to move. The bottom rod 15 drives the fire blanket 19 to move above the adsorption magnet 14. Then, the permanent magnet 18 on the outer cylinder 16 and the adsorption magnet 14 are magnetically attracted to each other, causing the outer cylinder 16 to move downward and compress the return spring 17. The permanent magnet 18 and the adsorption magnet 14 are magnetically attracted to each other, causing one end of the fire blanket 19 to be in a closed state. When the temperature of the box body 1 rises, the temperature inside the air storage tank 131 rises. After the nitrogen expands due to the heat, the nitrogen pushes the rubber membrane 132 to expand. Multiple groups of rubber membranes 132 are squeezed against the fire blanket 19 inside the groove 13, so that the surface of the fire blanket 19 is squeezed close to the inner wall of the groove 13.

[0030] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 11 、 Figure 12 The driving component 3 includes a conveying hole 31. The inner wall of the box body 1 is provided with a conveying nozzle 333 connected to the upper conveying trough 33. The inner wall of the box body 1 is hollowed out to form a conveying hole 31. The conveying hole 31 is connected to the lower conveying trough 32. The box body 1 is hollowed out to form a mouth-shaped lower conveying trough 32. The box body 1 is hollowed out to form a mouth-shaped upper conveying trough 33. The lower conveying trough 32 is connected to the upper conveying trough 33. A guide wheel 34 is rotatably connected to the lower conveying trough 32. The center of the bottom circle of the guide wheel 34 is fixedly connected to the driving rod 35. The driving rod 35 is connected to the box body. The bottom of the housing 1 is rotatably connected, and a cross groove is provided in the bottom area of the driving rod 35 to facilitate the rotation of the driving rod 35 by twisting with an external tool. The upper end of the guide wheel 34 is fixedly connected to the insertion rod 36, which is located in the groove in the top area of the housing 1. The upper end of the insertion rod 36 is slidably inserted into the bolt 37, and the protrusion on the side wall of the insertion rod 36 is slidably connected to the limiting groove 38 in the bolt 37; a gas generator is fixed inside the delivery hole 31; the gas generator uses the same generator as the airbag, which can generate a large amount of high-pressure nitrogen at the moment of reaction; The guide wheel 34, drive rod 35, insertion rod 36, and bolt 37 are rotatably arranged on the box body 1. During the installation and disassembly process, the guide wheel 34, drive rod 35, insertion rod 36, and bolt 37 do not break away from the connection with the box body 1, thereby improving the speed of connecting the four corners of the box body 1.

[0031] The battery pack is installed in the box body 1, and then the box cover 2 is placed on the box body 1, and the driving rod 35 is twisted to rotate. The driving rod 35 drives the insertion rod 36 and the bolt 37 to rotate, and the bolt 37 is screwed into the box cover 2. The box body 1 is moved and installed to the installation area of the automobile chassis area by a carrying device, and then the driving rod 35 is continued to be twisted. The driving rod 35 drives the bolt 37 to rotate, and the bolt 37 is connected to the automobile chassis, so that the box body 1 is fixed to the bottom of the car; when the vehicle collides with the outside world, the battery pack in the box body 1 burns, and the gas generator in the delivery hole 31 quickly produces a large amount of nitrogen. At this time, the high-pressure ammonia enters the lower delivery trough 32 through the delivery hole 31, and then drives the guide wheel 34 in the lower delivery trough 32 to rotate, and then enters the upper delivery trough 33, and is delivered to the four corners of the box body 1 through the transmission nozzle 333 connected to the upper delivery trough 33, so that the box body 1 can be evenly filled with nitrogen, avoiding the nitrogen being concentrated in a single area for delivery; When the guide wheel 34 rotates, it also drives the insertion rod 36 to rotate. The insertion rod 36 twists the bolt 37 in the opposite direction, so that the bolt 37 and the box body 1 are separated from the vehicle chassis area. The electric push rod 52 pushes the cutter 53 to shear the high-voltage cable, so that the cable is cut off.

[0032] Reference Figure 4The side wall of the groove 13 is recessed inward to form an air storage groove 131. A rubber membrane 132 is fixedly connected to the outer end surface of the air storage groove 131. The rubber membrane 132 wraps the air storage groove 131 into a closed space, and the closed space is filled with nitrogen. There are multiple groups of rubber membranes 132 and air storage grooves 131, which are arranged on the side walls of the groove 13 from top to bottom respectively. The rubber membrane 132 is made of fluororubber.

[0033] Reference Figure 1 、 Figure 2 、 Figure 5 、 Figure 9 、 Figure 10 The receiving assembly 4 includes a receiving frame 41, which is fixedly connected to the bottom of the box body 1. A plurality of first one-way valves 42 and second one-way valves 43 are equidistantly provided on the top of the receiving frame 41 from left to right. The upper end connection ports of the first one-way valves 42 and the second one-way valves 43 are connected to the inside of the box body 1, and the lower ends of the first one-way valves 42 and the second one-way valves 43 are connected to the inside of the receiving frame 41; it is convenient to extract or transport the air at the front and rear ends of the box body 1, so that the air can flow more evenly in the box body 1; A first spring damper 44 is fixedly connected to the top of the accommodating frame 41, and the bottom of the first spring damper 44 is fixedly connected to the heat conducting frame 45. The heat conducting frame 45 is hollowed out to form a accommodating cavity 46, and the accommodating cavity 46 is filled with a heat absorbing medium. A drainage frame 47 is fixedly connected to the bottom of the heat conducting frame 45, and the drainage frame 47 is hollowed out to form a diversion cavity 48. A second spring damper 49 is fixedly connected to the bottom of the drainage frame 47, and a contact plate 410 is fixedly connected to the bottom of the second spring damper 49. A pressure sensor is fixedly connected to the bottom of the drainage frame 47; when the contact plate 410 is hit by an object, the contact plate 410 is forced to apply pressure to the pressure sensor, so that the pressure sensor senses the impact force; the air buffer is triggered by the compression stroke of the second spring damper 49 and the first spring damper 44 and the displacement of the heat conducting frame 45 to form a multi-stage buffering effect.

[0034] The vehicle's running airflow is used to pass through the guide cavity 48 to achieve forced convection heat dissipation, and the heat absorbing medium in the heat conduction frame 45 is used to reduce the operating temperature of the battery pack.

[0035] When a car is driving on the road, the front of the car divides the air in front into two parts. One part of the airflow flows along the roof and sides of the car body (upper airflow), and the other part passes under the chassis (lower airflow). The airflow passes through the guide cavity 48 in the guide frame 47, causing the air to flow from left to right in the guide frame 47 to exchange heat with the guide frame 47. The guide frame 47 contacts the heat conduction frame 45. The heat conduction frame 45 can dissipate heat and cool down with the help of the guide frame 47 and the airflow generated by the air division when the car moves forward. When the vehicle chassis is hit, the external object first hits the contact plate 410, causing the contact plate 410 to transmit pressure to the pressure sensor and compress and push the second spring damper 49. The second spring damper 49 pushes the drainage frame 47 to move, and the drainage frame 47 drives the heat transfer frame 45 to move. The heat transfer frame 45 pushes the air above the receiving frame 41 into the box body 1 through the first one-way valve 42. Then, when the heat transfer frame 45 returns to its downward position, the air in the box body 1 is drawn through the second one-way valve 43 into the space above the receiving frame 41 for heat exchange and to prepare for the next heat exchange. When the car encounters an uneven road surface, the chassis of the vehicle will shake up and down during driving, and the shaking of the chassis will drive the heat conduction frame 45 to shake up and down, so that the heat conduction frame 45 pushes the air in the receiving frame 41 back and forth to exchange heat with the box body 1.

[0036] Reference Figure 6 The shearing assembly 5 includes a shearing groove 51, which is hollowed out in the box body 1 to form a shearing groove 51. An electric push rod 52 is fixedly connected to the shearing groove 51. The telescopic end of the electric push rod 52 is fixedly connected to the cutter 53. The cutter 53 is made of a ceramic blade. A through hole 54 is formed through the side wall of the box body 1. The high-voltage cable is connected to the battery pack in the box body 1 through the through hole 54. When the box body 1 is installed in the chassis area of the vehicle body, the high-voltage cable is connected to the vehicle and energized; By controlling the electric push rod 52 to drive the cutter 53 to move, the cutter 53 moves and cuts the high-voltage cable, so that the high-voltage cable on the box 1 is separated from the vehicle, making it convenient for the box 1 to fall downward without any other connection area with the vehicle, and making it convenient for the box 1 to automatically move out of the area under the vehicle chassis.
