Description

Technical Field

[0001] This invention relates to the field of battery protection technology, specifically to a new energy battery protection device. Background Technology

[0002] Batteries are a core component of hybrid electric vehicles (HEVs) and pure electric vehicles in the new energy vehicle sector. They directly affect the vehicle's performance and driving range, and are a key factor in the industrialization of HEVs and pure electric vehicles. Ensuring the reliable and safe operation of new energy vehicles hinges on the reliability and safety of their power batteries, which requires not only optimizing battery structure but also improving heat dissipation performance.

[0003] A search revealed a new energy vehicle battery heat dissipation and protection device disclosed in publication number "CN109546032A". This device includes a housing and a cover. The bottom of the housing has two symmetrically arranged slide rails, each with two sliding blocks slidably connected to it. A flexible block for supporting the battery is bonded to the upper end of each sliding block. Pressure plates are fitted onto the two upper corners of the battery, with compression springs connected to the outer sides of the pressure plates. The compression springs have limiting sleeves connected to adjusting screws. A U-shaped partition is inserted through the center of the cover, with a tension spring connecting the inner side of the partition to the upper side of the cover. The partition divides the upper cavity of the housing into two parts. An intake fan is provided on one side of the partition, and an exhaust fan is provided on the other side. Cold air from the outside enters the internal cavity of the battery through the intake fan, circles the battery almost once, and is then discharged through the exhaust fan. This application uses intake and exhaust fans to cool the battery. However, the intake and exhaust fans themselves require power from the battery, which undoubtedly increases the workload of the battery, affects the battery's lifespan and the vehicle's range. In addition, adding intake and exhaust fans will occupy extra space, which would require reducing the size of the battery or changing the interior space of the vehicle to solve this problem. Based on this, the applicant has provided a new energy battery protection device. Summary of the Invention

[0004] This application proposes a new energy battery protection device to solve the problems mentioned in the background art, which use intake and exhaust fans for heat dissipation, increasing the workload of the battery, affecting the battery life and the vehicle's range, and also occupying extra space, requiring a reduction in battery size or changes to the vehicle's interior space.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] This invention discloses a new energy battery protection device, comprising a battery mounting base and a battery body located above the battery mounting base. A mounting ring is fixed to the outside of the battery body and is bolted to the upper surface of the battery mounting base. The battery mounting base has a rectangular cavity structure. A movable plate is movably disposed on one side of the bottom wall of the battery mounting base, and multiple heat dissipation holes are opened on the other side of the bottom wall. Connecting columns are symmetrically fixed to the lower surface of the movable plate. A movable plate is fixed to the bottom ends of two connecting columns. Multiple air inlets are fixed between the movable plate and the movable plate. A dustproof net is provided at one end of each air inlet, and an air inlet pipe is connected to the other end of the air inlet, with one end of the air inlet pipe extending into the battery mounting base. Baffles are symmetrically fixed to the upper surface of the movable plate. Multiple heat-conducting plates are installed on the top wall of the battery mounting base, and heat dissipation strips are fixed to the bottom wall of the heat-conducting plates.

[0007] As a preferred embodiment of the present invention, multiple mounting ears are fixed on both sides of the battery mounting base, and mounting holes are provided on the mounting ears.

[0008] As a preferred embodiment of the present invention, the number of heat dissipation strips is the same as the number of air inlet pipes. The bottom end of the heat dissipation strip is fixed to the bottom wall of the battery mounting base. Ventilation holes are provided on the heat dissipation strip along its length. One end of the air inlet pipe that extends into the battery mounting base is fixed in the ventilation hole.

[0009] As a preferred embodiment of the present invention, a ventilation box is fixed on the bottom wall of the battery mounting base. Multiple air inlets are evenly opened on the side wall of the ventilation box near the heat sink, and the multiple air inlets correspond to multiple ventilation holes respectively. Multiple air outlets are opened on the bottom wall of the ventilation box, and the multiple air outlets correspond to multiple heat sink holes respectively.

[0010] As a preferred embodiment of the present invention, electric push rods are symmetrically installed on the inner surface of the top wall of the battery mounting base. Pull ropes are connected to the output shaft ends of the electric push rods. Fixing rings are symmetrically installed on the inner surface of the top wall of the battery mounting base. One end of each of the two pull ropes passes through the two fixing rings, and the ends of the two pull ropes passing through the fixing rings are connected to the movable plate.

[0011] As a preferred embodiment of the present invention, a temperature sensor is installed on the inner surface of the bottom wall of the battery mounting base, and a controller is installed on one inner wall of the battery mounting base. The temperature sensor is electrically connected to the controller, and the controller is electrically connected to the electric push rod.

[0012] The beneficial effects of this invention are:

[0013] 1. By setting up structures such as movable plate one, movable plate two, air inlet duct, dustproof net, air inlet pipe, heat conduction plate and heat dissipation strip, when the vehicle is in motion, the cold air from the outside enters the interior of the battery mounting base through the air inlet duct and air inlet pipe. The heat conduction plate contacts the bottom of the battery body and absorbs the heat generated by the battery body when it is working. The heat dissipation strip absorbs the heat from the heat conduction plate. The airflow of cold air carries away the heat from the heat dissipation strip and discharges it through the heat dissipation holes. This effectively dissipates and protects the battery body. Moreover, the structure is set inside the battery mounting base, which does not take up extra space and does not require additional energy consumption, thus ensuring the service life of the battery body.

[0014] 2. By setting ventilation holes on the heat sink and fixing one end of the air inlet pipe inside the ventilation holes, the airflow path is fixed and the airflow fully contacts the heat sink, which not only improves the heat dissipation effect, but also improves the heat absorption effect of the heat conduction plate by utilizing the radiation of the heat sink.

[0015] 3. By setting up a ventilation box, the heat carried away by the airflow can be quickly discharged to the outside of the battery mounting base, which can effectively reduce the temperature inside the battery mounting base and further improve the heat dissipation effect.

[0016] 4. By setting up electric push rods, pull ropes, and fixing rings, when the car is stopped or the temperature is low in winter and the battery body does not need to dissipate heat, movable plate one and movable plate two can be stored inside the battery mounting base, so that the equipment is not exposed to the outside all the time, which also extends the service life of the equipment. At the same time, movable plate two can also keep the battery mounting base flat. Attached Figure Description

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0027] Please see Figure 1-5 As shown, a new energy battery protection device includes a battery mounting base 1 and a battery body 2 located above the battery mounting base 1. A mounting ring 3 is fixed to the outside of the battery body 2, and the mounting ring 3 is fixed to the upper surface of the battery mounting base 1 by bolts. The battery mounting base 1 has a rectangular cavity structure. A movable plate 5 is movably arranged on one side of the bottom wall of the battery mounting base 1, and multiple heat dissipation holes 11 are opened on the other side of the bottom wall of the battery mounting base 1. Connecting columns 6 are symmetrically fixed on the lower surface of the movable plate 5. The bottom ends of the two connecting columns 6 are jointly fixed to a movable plate 7. Multiple air inlets 8 are fixed between the movable plate 5 and the movable plate 7. A dustproof net 9 is provided at one end of the air inlet 8, and an air inlet pipe 10 is connected to the other end of the air inlet 8. One end of the air inlet pipe 10 extends into the battery mounting base 1. A baffle 12 is symmetrically fixed on the upper surface of the movable plate 5. Multiple heat-conducting plates 13 are installed on the top wall of the battery mounting base 1, and heat dissipation strips 14 are fixed on the bottom wall of the heat-conducting plates 13.

[0028] Working process: The battery body 2 is installed on the battery mounting base 1, with the bottom of the battery body 2 contacting the heat-conducting plate 13. Then, the equipment is lifted to the chassis of the new energy vehicle using a lift for installation. Multiple air inlets 8 are set between the movable plate 1 5 and the movable plate 2 7. The baffle 12 can prevent the movable plate 1 5 from falling off the battery mounting base 1. When the car is moving, the cold air from the outside enters the interior of the battery mounting base 1 through the air inlets 8 and the air inlet pipe 10. The dustproof net 9 on the air inlets 8 can prevent dust from entering the battery mounting base 1. The heat-conducting plate 13 absorbs the heat generated by the battery body 2 during operation. The heat dissipation strip 14 absorbs the heat from the heat-conducting plate 13. The airflow of cold air carries away the heat from the heat dissipation strip 14 and discharges it through the heat dissipation hole 11, effectively dissipating and protecting the battery body 2. Moreover, the structure is set inside the battery mounting base 1, which does not occupy extra space and does not require additional energy consumption, thus ensuring the service life of the battery body 2.

[0029] Please see Figure 1-2 As shown, multiple mounting ears 4 are fixed on both sides of the battery mounting base 1, and mounting holes are provided on the mounting ears 4; the battery mounting base 1 can be easily fixed to the chassis of the car through the mounting ears 4.

[0030] Please see Figure 5 As shown, the number of heat dissipation strips 14 is the same as the number of air inlet pipes 10. The bottom end of the heat dissipation strip 14 is fixed to the bottom wall of the battery mounting base 1. Ventilation holes 15 are provided on the heat dissipation strip 14 along its length. One end of the air inlet pipe 10 that extends into the battery mounting base 1 is fixed in the ventilation hole 15. By fixing one end of the air inlet pipe 10 in the ventilation hole 15, the airflow path is fixed, and the airflow fully contacts the heat dissipation strip 14, which not only improves the heat dissipation effect, but also improves the heat absorption effect of the heat conduction plate 13 by utilizing the radiation of the heat dissipation strip 14.

[0031] Please see Figure 5-6 As shown, a ventilation box 16 is fixed on the bottom wall of the battery mounting base 1. Multiple air inlets 17 are evenly opened on the side wall of the ventilation box 16 near the heat sink 14, and the multiple air inlets 17 correspond to multiple ventilation holes 15 respectively. Multiple air outlets 18 are opened on the bottom wall of the ventilation box 16, and the multiple air outlets 18 correspond to multiple heat dissipation holes 11 respectively. The airflow enters the ventilation box 16 directly through the ventilation holes 15 and the air inlets 17, and then is discharged to the outside of the battery mounting base 1 through the air outlets 18 and the heat dissipation holes 11. The airflow path is fixed, so that heat can be quickly discharged, further improving the heat dissipation effect.

[0032] Please see Figure 7As shown, electric push rods 19 are symmetrically installed on the inner surface of the top wall of the battery mounting base 1. The output shaft of the electric push rod 19 is connected to a pull rope 20. Fixing rings 21 are symmetrically installed on the inner surface of the top wall of the battery mounting base 1. One end of each of the two pull ropes 20 passes through the two fixing rings 21, and the ends of the two pull ropes 20 passing through the fixing rings 21 are connected to the movable plate 5. When the car is stopped or the temperature is low in winter and the battery body 2 does not need to dissipate heat, the movable plate 5 and the movable plate 7 can be stored inside the battery mounting base 1, so that the equipment is not exposed to the outside all the time, which also extends the service life of the equipment. At the same time, the movable plate 7 is flush with the bottom of the battery mounting base 1, which keeps the battery mounting base 1 flat.

[0033] Please see Figure 7 As shown, a temperature sensor 22 is installed on the inner surface of the bottom wall of the battery mounting base 1, and a controller 23 is installed on one inner wall of the battery mounting base 1. The temperature sensor 22 is electrically connected to the controller 23, and the controller 23 is electrically connected to the electric push rod 19. The temperature sensor 22 monitors the temperature inside the battery mounting base 1 in real time. When the temperature detected by the temperature sensor 22 is low, the air inlet duct 8 is stored inside the battery mounting base 1. When the temperature detected by the temperature sensor 22 is high, the signal is transmitted to the controller 23. The controller 23 controls the electric push rod 19 to start, lowering the movable plate 7 to the outside of the battery mounting base 1. To ensure a smooth lowering process, the vehicle speed can be reduced or the vehicle can be temporarily stopped on the side of the road. The vehicle can be driven normally again after the movable plate 7 has completely descended, to avoid excessive airflow during the lowering process that would prevent the movable plate 7 from being lowered smoothly.

[0034] Working principle: In use, the battery body 2 is bolted onto the battery mounting bracket 1. Then, a lift is used to raise the battery mounting bracket 1 to below the vehicle chassis. The mounting ears 4 of the battery mounting bracket 1 are aligned with the mounting bracket on the vehicle chassis, and then installation is performed. The temperature sensor 22 monitors the temperature inside the battery mounting bracket 1 in real time. When the temperature detected by the temperature sensor 22 is low, the air intake duct 8 is retracted inside the battery mounting bracket 1. When the temperature detected by the temperature sensor 22 is high, the signal is transmitted to the controller 23, and the controller 23 controls... When the electric push rod 19 is activated, its output shaft moves to the left, causing the pull rope 20 to move to the left, lowering the movable plate 2 7 to the outside of the battery mounting base 1. To ensure stability during the lowering process, the vehicle speed can be reduced or the vehicle can be temporarily stopped on the side of the road. The vehicle can be driven normally again after the movable plate 2 7 has completely descended. This is to prevent excessive airflow during the lowering process from causing the movable plate 2 7 to be unable to descend smoothly. The movable plate 1 5 is equipped with a stop bar 12 to prevent the movable plate 1 5 from detaching from the battery mounting base 1. The movable plate 1 5 and the stop bar 12 are locked on the bottom wall of the battery mounting base 1, ensuring good stability.

[0035] During vehicle operation, cold air from the outside enters the battery mounting bracket 1 through the air intake duct 8 and air intake pipe 10. The dustproof net 9 on the air intake duct 8 prevents dust from entering the battery mounting bracket 1. The heat conduction plate 13 absorbs the heat generated by the battery body 2 during operation, and the heat dissipation strip 14 absorbs the heat from the heat conduction plate 13. One end of the air intake pipe 10 is fixed in the ventilation hole 15, fixing the airflow path and ensuring full contact between the airflow and the heat dissipation strip 14. The cold airflow carries away the heat from the heat dissipation strip 14. The airflow enters the ventilation box 16 directly through the ventilation hole 15 and air intake hole 17, and then is discharged to the outside of the battery mounting bracket 1 through the air outlet 18 and heat dissipation hole 11. The fixed airflow path allows heat to be quickly discharged, effectively dissipating heat and protecting the battery body 2. The overall structure is set inside and below the battery mounting bracket 1, without occupying extra space or requiring additional energy consumption. Only the electric push rod 19 consumes some power during operation, ensuring the service life of the battery body 2.
