Description

Technical Field

[0001] This invention relates to the field of new energy vehicle battery technology, specifically an explosion-proof housing structure for new energy vehicle batteries. Background Technology

[0002] The battery casing of a new energy vehicle is a key structural component that encloses and protects the battery pack. Its main functions are to isolate it from external environmental influences such as collisions, vibrations, water, and dust, while providing a stable installation space for the battery pack and assisting in heat conduction (in conjunction with the cooling system). The material used is largely chosen based on the vehicle's positioning and requirements. Mainstream options include aluminum alloy casings (lightweight and corrosion-resistant, suitable for most family and mid-to-high-end vehicles) and steel casings (low cost, high strength, commonly used in commercial vehicles or entry-level models). Some high-end models also utilize carbon fiber composite casings for further weight reduction. Furthermore, the battery casing needs to be designed in conjunction with the battery management system (BMS) and seals to meet stringent waterproof and dustproof standards (typically IP67 / IP68 levels) and to buffer impact forces through structural deformation in extreme situations, ensuring the safety of the battery pack.

[0003] Chinese patent CN119297505B discloses a shape memory alloy-driven self-detaching easy-to-install new energy vehicle battery pack, including a bottom shell and a cover plate forming a receiving cavity. The receiving cavity contains a frame, an inner shell, and a battery assembly. The frame is connected to both the bottom shell and the inner shell, and the inner shell is connected to the battery assembly. The frame includes a bottom frame with several telescopic rods connected to it. Each telescopic rod has an automatic detachment device at its telescopic end. The automatic detachment device includes a first slider with a groove, a first spring connected within the groove, a folding lever connected to the free end of the first spring, and a second slider connected to the free end of the folding lever. The side wall of the bottom shell has several first through holes. The folding lever is made of a folding shape memory alloy. This invention solves the problem of battery packs spontaneously combusting when heated, which could cause injury or death to occupants and vehicle fire.

[0004] As shown in the aforementioned patent, in the field of new energy vehicle safety protection technology, regarding the technical problem of vehicle combustion caused by battery pack thermal runaway, existing technologies propose a solution: setting an automatic separation device between the vehicle body and the battery pack. The initial design intention is that when the battery pack spontaneously combusts, this automatic separation device drives the battery pack to disconnect from the vehicle body, thus cutting off the transmission path of the combustion source to the vehicle body and preventing vehicle combustion damage. However, this technical solution has significant technical defects in practical application: when a new energy vehicle is in driving condition, the battery pack, after being separated by the automatic separation device, will fall directly onto the road surface, forming a road obstacle. This fallen battery pack may remain in a burning or high-temperature state, and is prone to collision with other vehicles traveling on the same road, potentially triggering a chain of road traffic accidents, causing significant property damage, and posing a serious threat to the personal safety of road users, making it difficult to meet the comprehensive safety requirements of actual road driving scenarios.

[0005] Therefore, it is necessary to provide an explosion-proof housing structure for new energy vehicle batteries to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide an explosion-proof housing structure for new energy vehicle batteries, which effectively solves the technical problem that existing automatic separation devices cause the battery pack to fall directly onto the road surface after separation under vehicle driving conditions, creating a safety hazard.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an explosion-proof housing structure for a new energy vehicle battery, comprising a protective frame, an elastic connecting component, a sliding connecting component, a battery housing disposed inside the protective frame, and two parallel guide rails disposed above the protective housing. Each of the two guide rails has a sliding seat slidably installed in it. The sliding seat is disposed on the side near the front of the vehicle. The sliding seat is connected to the protective frame through the elastic connecting component and the sliding connecting component. The guide rails are provided with locking components for locking the protective frame.

[0008] A further configuration of the present invention is as follows: the elastic connection assembly includes a telescopic rod, a connecting seat, and a spring; the top ends of the spring and the telescopic rod are fixedly connected to a slide seat; the bottom ends of the spring and the telescopic rod are fixedly connected to the connecting seat; and the connecting seat is connected to the protective frame via a sliding connection assembly.

[0009] A further configuration of the present invention is as follows: the sliding connection assembly includes a support rod and a sliding sleeve, two sliding connection assemblies are provided, and the two sliding connection assemblies are respectively provided on both sides of the protective frame. The sliding sleeve is fixedly connected to the side wall of the protective frame. One end of the support rod is fixedly connected to the connecting seat, and a limit block is fixedly installed on the other end of the support rod. The support rod passes through the sliding sleeve, and the support rod and the sliding sleeve are slidably engaged.

[0010] A further provision of the present invention is that: a mounting bracket is fixedly installed on the side wall of the guide rail, a guide post is fixedly installed on the bottom wall of the mounting bracket, a limiting seat is fixedly installed on the side wall of the protective frame, the guide post passes through the limiting seat, and the guide post and the limiting seat are slidably engaged.

[0011] A further configuration of the present invention is as follows: the locking assembly includes a protective shell, an electric push rod fixedly disposed within the protective shell, and a locking block fixedly connected to the output end of the electric push rod; the limiting seat has a locking groove, and the locking block is inserted into the locking groove.

[0012] A further provision of the present invention is that: an mounting cylinder is fixedly installed on the side of the guide rail away from the front of the vehicle, an elastic pull rope is provided on the inner side of the guide rail, one end of the elastic pull rope extends into the mounting cylinder and is fixedly connected to the inner wall of the mounting cylinder, and the other end of the elastic pull rope is fixedly connected to the slide block, and the elastic pull rope is in a stretched state.

[0013] A further feature of the present invention is that a bottom guard plate is fixedly installed on the bottom wall of the protective frame, and a plurality of rollers are embedded in the bottom of the bottom guard plate.

[0014] A further feature of the present invention is that a locking block is provided on the inner wall of the guide rail near the mounting cylinder, and a locking groove is provided on the side of the slide near the mounting cylinder, wherein the locking block and the locking groove are adapted to each other.

[0015] A further feature of the present invention is that: a locking hole is provided on the side of the support rod near the limiting seat; an mounting base is fixedly installed on the sliding sleeve; a second locking block is slidably installed inside the mounting base; the second locking block is elastically connected to the inner side wall of the mounting base; and the second locking block is adapted to the locking hole.

[0016] A further feature of the present invention is that: a plurality of temperature sensors are provided on the upper surface of the battery casing, and a connector is provided on one side of the top of the protective frame, the connector being electrically connected to the battery pack inside the battery casing.

[0017] In summary, the present invention has the following beneficial effects: By configuring a protective frame, elastic connecting components, sliding connecting components, and locking components, the present invention constructs a three-level protection mechanism of "first downward detachment, then directional sliding, and finally stable locking," effectively solving the technical problem of existing automatic separation devices where the battery pack directly falls to the road surface after separation under vehicle driving conditions, creating a safety hazard. After the locking component is released, the elastic connecting component drives the protective frame and battery casing to smoothly detach along the guide post, preventing direct fall. The elastic pull rope pulls the sliding block along the guide rail, cooperating with the sliding guide of the sliding sleeve and support rod to achieve directional sliding of the battery pack towards the rear of the vehicle. The locking cooperation between the first locking block and the first locking slot, and the second locking block and the locking hole, fixes the battery pack 0.5-1 meters behind the rear of the vehicle, achieving the effect of preventing the battery pack from falling to the road surface and avoiding it becoming a road obstacle, thus eliminating the risk of a chain of traffic accidents caused by the battery pack falling. By setting up temperature sensors, comprehensive and accurate monitoring of the battery pack temperature and operating status is achieved. After the temperature sensors transmit abnormal signals to the control system, the control system can promptly activate the early warning mechanism and adjust the battery operating status to delay the thermal runaway process. At the same time, the locking components are triggered to unlock the battery pack to achieve battery pack separation, achieving the effect of early warning and proactive prevention. By setting up the bottom guard plate and rollers, with the roller axis direction parallel to the vehicle width direction, the friction between the protective frame and the ground is reduced when the protective frame moves, achieving the effect of smooth movement of the battery pack.

[0020] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] Please see Figures 1-9 In this embodiment of the invention, an explosion-proof housing structure for a new energy vehicle battery includes a protective frame 1, an elastic connecting component, a sliding connecting component, a battery housing 2 disposed inside the protective frame 1, and two parallel guide rails 4 disposed above the protective housing 16. The protective frame 1 and the battery housing 2 are made of explosion-proof material. A slide block 401 is slidably installed in each of the two guide rails 4, and the slide block 401 is located on the side near the front of the vehicle. The slide block 401 is connected to the protective frame 1 through the elastic connecting component and the sliding connecting component. A locking component for locking the protective frame 1 is provided on the guide rail 4. The guide rail 4 is fixedly connected to the vehicle frame. Compared to the risk of the battery pack falling directly to the road after separation in the prior art, the present invention... The explosion-proof housing structure provides enveloping protection for the battery housing 2 through the protective frame 1. Combined with the buffer support provided by the elastic connection component and the directional guidance of the sliding connection component, the battery pack remains under control during the separation process. This prevents it from directly impacting the road surface and causing structural damage or sparks due to loss of support. Furthermore, the cooperation between the guide rail 4 and the slide block 401, along with the auxiliary traction of the elastic pull rope 20, ensures that the battery pack moves smoothly along a preset trajectory to a safe distance behind the vehicle. At the same time, the roller 23 design of the bottom guard plate 22 further reduces the frictional resistance with the road surface during movement, avoiding additional safety hazards caused by friction. This fundamentally eliminates the possibility of the separated battery pack becoming an obstacle on the road, providing more comprehensive protection for road traffic safety.

[0022] In this embodiment, preferably, the elastic connection assembly includes a telescopic rod 5, a connecting seat 6, and a spring 7. The top ends of the spring 7 and the telescopic rod 5 are fixedly connected to the slide seat 401, and the bottom ends of the spring 7 and the telescopic rod 5 are fixedly connected to the connecting seat 6. Two elastic connection assemblies are provided to improve the stability of the support for the protective frame 1. Each set of elastic connection assemblies includes multiple telescopic rods 5 to improve the support stability. The connecting seat 6 is connected to the protective frame 1 through a sliding connection assembly. The sliding connection assembly includes a support rod 8 and a sliding sleeve 9. Two sliding connection assemblies are provided, and the two sliding connection assemblies are respectively located on both sides of the protective frame 1. The sliding sleeve 9 is fixedly connected to the side wall of the protective frame 1. One end of the support rod 8 is fixedly connected to the connecting seat 6, and the other end of the support rod 8 is fixedly installed with a limit block 10. The support rod 8 passes through the sliding sleeve 9, and the support rod 8 and the sliding sleeve 9 are in sliding cooperation. When the vehicle detects that the battery pack inside the battery casing 2 has an abnormal temperature such as overheating or smoke, the locking assembly releases the lock on the protective frame 1, allowing the protective frame 1 to move under the elastic action of the spring 7. The downward movement causes the protective frame 1 and the inner battery casing 2 to move downwards, separating them from the vehicle's interior. Subsequently, under the wind resistance of the vehicle's movement, the slide block 401 moves on the guide rail 4, causing the protective frame 1 to slide away from the front of the vehicle. Simultaneously, the sliding sleeves 9 on both sides of the protective frame 1 slide on the support rod 8, causing the sliding sleeves 9 and the protective frame 1 to move together away from the connecting seat 6. Ultimately, the protective frame 1 and the battery casing 2 move completely out from under the vehicle, maintaining a distance of 0.5 to 1 meter from it. This ensures that if the battery burns or explodes, it will not directly impact the vehicle, guaranteeing vehicle safety and preventing spontaneous combustion or explosion. Furthermore, even if the battery pack is separated, it will not be directly thrown onto the road but will move with the vehicle, maintaining a greater distance from following vehicles, thus preventing other vehicles from colliding with the battery pack and causing a chain reaction accident, significantly improving safety. Moreover, by restricting the movement direction of the protective frame 1 through the slide block 401 and the support rod 8, it effectively prevents the protective frame 1 from contacting the wheels when separating from the vehicle, thus avoiding secondary accidents.

[0023] In this embodiment, preferably, a mounting bracket 13 is fixedly installed on the side wall of the guide rail 4, a guide post 15 is fixedly installed on the bottom wall of the mounting bracket 13, and a limiting seat 14 is fixedly installed on the side wall of the protective frame 1. The guide post 15 passes through the limiting seat 14, and the guide post 15 and the limiting seat 14 are slidably engaged. Through the limiting effect of the guide post 15 and the limiting seat 14, the protective frame 1 and the battery housing 2 will not deviate when moving downward under the elastic action of the elastic connection assembly, ensuring that the battery pack can move downward smoothly to detach from the vehicle. When the protective frame 1 moves downward to its limit position, the limiting seat 14 separates from the guide post 15, without affecting the horizontal movement of the protective frame 1 relative to the vehicle; the locking group The component includes a protective shell 16, an electric push rod 17 fixedly disposed within the protective shell 16, and a locking block 18 fixedly connected to the output end of the electric push rod 17. The limiting seat 14 has a locking groove 1401, and the locking block 18 is inserted into the locking groove 1401. When the locking block 18 is inserted into the locking groove 1401, the limiting seat 14 is locked, preventing the protective frame 1 from moving downward. When the battery pack temperature is abnormal and spontaneous combustion occurs, the output end of the electric push rod 17 is controlled to retract, thereby driving the locking block 18 to move, causing the locking block 18 to move out of the locking groove 1401, thereby releasing the lock on the limiting seat 14, and allowing the protective frame 1 to move downward under the elastic action of the elastic connecting component.

[0024] In this embodiment, preferably, an mounting cylinder 19 is fixedly installed on the side of the guide rail 4 away from the front of the vehicle. An elastic pull rope 20 is provided on the inner side of the guide rail 4. One end of the elastic pull rope 20 extends into the mounting cylinder 19 and is fixedly connected to the inner wall of the mounting cylinder 19. The other end of the elastic pull rope 20 is fixedly connected to the slide block 401. The elastic pull rope 20 is in a stretched state. When the protective frame 1 moves downward until the limit seat 14 separates from the guide post 15, the slide block 401 moves towards the mounting cylinder 19 under the tension of the elastic pull rope 20, thereby driving the protective frame 1 and the battery casing 2 to move away from the front of the vehicle. This increases the moving speed of the battery pack in case of abnormality, allowing the battery pack to quickly move away from the vehicle and further improve safety.

[0025] In this embodiment, preferably, a bottom guard plate 22 is fixedly installed on the bottom wall of the protective frame 1, and a plurality of rollers 23 are embedded in the bottom of the bottom guard plate 22. The axial direction of the rollers 23 is parallel to the width direction of the vehicle. When the protective frame 1 moves, the rollers 23 will roll along the vehicle's driving direction. Because the axial direction of the rollers 23 is parallel to the width direction of the vehicle, this design effectively reduces the friction between the protective frame 1 and the ground.

[0026] In this embodiment, preferably, multiple temperature sensors 24 are provided on the upper surface of the battery casing 2. These temperature sensors 24 are evenly distributed on the upper surface, enabling comprehensive and accurate monitoring of temperature changes inside the battery casing 2. The temperature sensors 24 are connected to the vehicle's control system. Once an abnormal rise in battery temperature is detected, a signal is quickly transmitted to the control system. Upon receiving the signal, the control system immediately activates an early warning mechanism to alert the driver that there may be a safety hazard with the battery. Simultaneously, the control system automatically adjusts the battery's operating state based on the degree and rate of temperature increase, such as reducing the charging or discharging power, to prevent the battery temperature from rising further and avoid dangerous situations such as battery explosion due to high temperature. In addition, the temperature sensors 24 also have a data recording function, which records the battery's temperature data under different operating conditions in real time. This data can provide important basis for subsequent battery performance analysis and fault diagnosis, facilitating technicians to assess and maintain the battery's health status. Furthermore, when the battery pack temperature is too high and spontaneous combustion or explosion occurs, the control system can control the locking component to release the lock on the protective frame 1 and the battery casing 2, allowing for timely separation of the battery pack from the vehicle. Smoke sensors can also be installed at the battery pack's installation location to monitor whether the battery pack is malfunctioning, enabling monitoring from multiple perspectives.

[0027] In this embodiment, preferably, a connector 3 is provided on one side of the top of the protective frame 1. The connector 3 is electrically connected to the battery pack inside the battery housing 2. A connector adapted to the connector 3 is provided inside the vehicle body. When the connector is inserted into the connector 3, the battery pack can supply power to the vehicle body. A backup battery is provided inside the vehicle so that when the battery pack inside the battery housing 2 fails, the backup battery can temporarily provide power so that the vehicle can drive to the side of the road and park.

[0028] Please see Figures 7-10 In this embodiment of the invention, the inner wall of the guide rail 4 near the mounting cylinder 19 is provided with a locking block 21, and the slide block 401 near the mounting cylinder 19 is provided with a locking groove (not shown in the figure). The locking block 21 is adapted to the locking groove. When the locking block 21 is inserted into the locking groove, the slide block 401 is locked on the side near the mounting cylinder 19, so that after the vehicle stops driving, the battery housing 2 and the protective frame 1 will not move back to directly under the vehicle under the action of inertia.

[0029] In this embodiment, preferably, a locking hole 801 is provided on the side of the support rod 8 near the limiting seat 14, and an mounting seat 11 is fixedly installed on the sliding sleeve 9. A second locking block 12 is slidably installed inside the mounting seat 11. The second locking block 12 is elastically connected to the inner side wall of the mounting seat 11, specifically through a spring 7. The second locking block 12 is adapted to the locking hole 801. When the protective frame 1 moves the sliding sleeve 9 on the support rod 8 to the locking hole 801, the second locking block 12 is inserted into the locking hole 801 under elastic action to lock the sliding sleeve 9, so that the sliding sleeve 9 can no longer slide on the support rod 8, thereby locking the protective frame 1 and the battery housing 2. After the vehicle stops driving, the battery housing 2 and the protective frame 1 are completely locked, and the battery pack is locked at a position 0.5 meters to 1 meter behind the rear of the vehicle.

[0030] Working principle: The core of this solution revolves around the "safe separation and directional control" principle when the battery pack is abnormal. The temperature sensor 24 monitors the internal state of the battery casing 2 in real time. When abnormalities such as excessive temperature or smoke are detected, the sensor transmits the signal to the vehicle control system. The control system first activates the warning and adjusts the battery working state, and then triggers the locking component to unlock. That is, it controls the electric push rod 17 to retract, so that the locking block 18 disengages from the locking groove 1401 of the limit seat 14, releasing the vertical constraint on the protective frame 1. At this time, the compressed spring 7 in the elastic connection component releases potential energy, which drives the protective frame 1 and the battery casing 2 to move smoothly down along the guide post 15 until the limit seat 14 separates from the guide post 15, realizing the initial detachment of the battery pack from the bottom of the vehicle. After the battery pack is removed, the solution achieves directional movement and stable locking through a dual-guide structure: on the one hand, the elastic rope 20 on the inner side of the guide rail 4, which is in a stretched state, pulls the slide block 401 to slide along the guide rail 4 towards the rear of the vehicle, simultaneously driving the protective frame 1 to move; on the other hand, the sliding sleeves 9 on both sides of the protective frame 1 slide along the support rod 8, limiting the movement trajectory, while the rollers 23 of the bottom guard plate 22 reduce friction with the ground during movement because their axis is parallel to the width direction of the vehicle; when the slide block 401 moves to the end of the guide rail 4, the first locking block 21 inserts into the first locking slot to achieve horizontal locking, and when the sliding sleeve 9 moves to the locking hole 801 of the support rod 8, the second locking block 12 inserts into the locking hole 801 under the elastic action to complete the locking of the sliding sleeve 9, finally fixing the protective frame 1 and the battery housing 2 0.5-1 meters behind the rear of the vehicle, realizing the safe separation of the battery pack from the vehicle and avoiding it becoming a road obstacle.
