Hydrogen energy automobile energy storage battery mounting structure

Abstract

The application provides a hydrogen energy automobile energy storage battery mounting structure and relates to the technical field of electric car energy storage. The hydrogen energy automobile energy storage battery mounting structure comprises a mounting mechanism and a protection mechanism. The protection mechanism is connected with the movable rod through the linkage structure of the lifting plate, and an efficient impact buffering mechanism is constructed. When the vehicle is subjected to collision in any direction (front, back, left and right), the lifting plate pushes the top block on the movable rod through the butt joint rod under the action of the impact force, the top block slides along the conical shaft body, and then the whole mounting mechanism is lifted up, so that the storage system slides and collapses along the stress direction. The design avoids the risk that the battery module directly bears the impact force in the traditional bolt rigid fixing mode, absorbs and disperses the impact energy through the active displacement of the structure, solves the safety hidden danger of the hydrogen energy battery fixing mode, and solves the problem of the safety risk of the battery structure damage and hydrogen leakage caused by the impact force directly acting on the battery body when the vehicle is subjected to collision in the traditional technology which generally adopts the bolt rigid fixing on the vehicle frame.

Description

Technical Field

[0001] This invention relates to the field of electric vehicle energy storage technology, and in particular to an installation structure for a hydrogen fuel cell battery for electric vehicles. Background Technology

[0002] Under the global trend of decarbonization and clean energy transformation and the development of the new energy vehicle industry, hydrogen energy has become an important development direction for new energy vehicles due to its advantages such as zero carbon emissions, high energy density, and fast refueling. The energy supply system of hydrogen fuel cell vehicles consists of fuel cell stacks, hydrogen storage systems, and energy storage modules. Among them, energy storage modules mostly use power battery packs, and some are equipped with supercapacitors. They undertake the key functions of energy recovery, instantaneous high power output, and assisting the stable operation of fuel cells. However, under actual complex operating conditions, the safety and stability of energy storage modules face challenges. In order to ensure that energy storage modules can operate safely and reliably under various operating conditions, they need to be firmly fixed to the vehicle frame with a special installation structure, thereby building a safe and reliable storage environment and providing a solid guarantee for the stable operation of the entire vehicle.

[0003] For example, application number CN202121771207.0 relates to a fuel cell stack packaging structure, a fuel cell module, and a fuel cell vehicle. The packaging structure includes an upper cover plate, a lower cover plate, a left side plate, a right side plate, a front end plate of the fuel cell stack, and a rear end plate of the fuel cell stack. The upper cover plate, lower cover plate, left side plate, and right side plate are all connected to the front end plate and the rear end plate of the fuel cell stack to form a whole. This utility model reduces the volume and weight of the fuel cell module and lowers the processing cost by incorporating the front end plate and the rear end plate of the fuel cell stack as part of the packaging structure and connecting the upper cover plate, lower cover plate, left side plate, and right side plate of the packaging structure to the front end plate and the rear end plate of the fuel cell stack to form a whole.

[0004] However, there are some shortcomings in the current design of automotive hydrogen energy storage systems:

[0005] First, the impact resistance of the storage structure lacks a static adjustment mechanism. Its factory-preset impact resistance coefficient cannot adapt to various scenarios in the actual use of the vehicle. In other words, it cannot flexibly adjust its impact resistance coefficient according to some usage scenarios of the vehicle, making it difficult for the storage structure to provide the best protection for hydrogen fuel cells under extreme conditions.

[0006] Secondly, the way hydrogen fuel cell batteries are fixed poses safety risks. Traditional technology generally uses bolts to rigidly fix them to the vehicle frame. When the vehicle is involved in a collision, the impact force will directly act on the battery body, which can easily cause safety risks such as damage to the battery structure and hydrogen leakage, thereby threatening the safety of passengers and public safety. The above-mentioned technical bottlenecks seriously restrict the improvement of the safety performance of hydrogen fuel cell vehicles and the industrialization process. Summary of the Invention

[0014] Preferably, the protection mechanism includes: a fixed base and an overlapping platform; the fixed base is a rectangular structure and has a rectangular groove inside; the overlapping platform is located at the four corners of the fixed base.

[0018] This invention provides a hydrogen fuel cell battery mounting structure for hydrogen fuel cell vehicles, which has the following advantages:

[0019] 1. In this invention, by setting a detachable stiffening plate and a multi-level cylindrical insertion structure inside the cover, the impact resistance coefficient of the storage system can be flexibly adjusted. When applied to ordinary civilian vehicles, the number of stiffening plates can be installed as needed. In special scenarios such as racing vehicles that are prone to collisions, the rigid support strength of the cover can be significantly improved by increasing the number of inserted stiffening plates, so that the impact resistance performance of the storage structure is precisely matched with the actual working conditions. This effectively overcomes the defects of the existing technology, which has fixed impact resistance performance and cannot adapt to complex usage scenarios, and provides good protection for hydrogen energy batteries.

[0020] 2. In this invention, the protection mechanism constructs an efficient impact buffer mechanism through the linkage structure of the lifting plate and the movable rod. When the vehicle suffers a collision in any direction (front, rear, left, or right), the lifting plate, under the impact force, pushes the top block on the movable rod through the connecting rod. The top block slides along the conical shaft, thereby lifting the entire mounting mechanism, causing the storage system to slide and collapse along the direction of the force. This design avoids the risk of the battery module directly bearing the impact force under the traditional bolt rigid fixing method. By absorbing and dispersing the impact energy through the active displacement of the structure, it significantly reduces safety hazards such as battery structure damage and hydrogen leakage, greatly improving the safety and reliability of hydrogen fuel cell vehicles under collision conditions.

[0039] As a third embodiment of the present invention, based on the first embodiment, such as Figure 3 and Figure 8As shown, the protection mechanism 2 includes: a fixed base 201 and an overlapping platform 2011; the fixed base 201 has a rectangular structure and a rectangular groove is provided inside the fixed base 201; the overlapping platform 2011 is located at the four corners of the fixed base 201; baffles 202 and telescopic blocks 2021; there are four sets of baffles 202, and the baffles 202 are located at the upper ends of the fixed base 201, and a rectangular groove is opened at the middle of the upper end of each set of baffles 202; the telescopic blocks 2021 are slidably installed in the rectangular grooves at the upper ends of each set of baffles 202 through elastic elements, and the telescopic blocks 2021 extend into the inner end of the fixed base 201; a lifting plate 203, a connecting rod 2031, and a shaft 2032; the lifting plate 203 is located inside the fixed base 201, and the lifting plate 2031... The four corners of the lifting plate 203 are placed on the overlapping platform 2011. The outer side of the lifting plate 203 contacts the baffle 202, and the lifting plate 203 can slide up and down along the baffle 202 inside the fixed seat 201. The connecting rods 2031 are vertically symmetrically arranged on both sides of the upper end of the lifting plate 203. The connecting rods 2031 will break when subjected to transverse shear force. The shaft 2032 is fixedly set at the middle position of the bottom of the lifting plate 203, and the shaft 2032 has a conical structure. The moving rod 204, the force plate 2041, and the top block 2042 are also present. The moving rod 204 is slidably installed around the fixed seat 201, and a rectangular block is set in the middle position of the moving rod 204, which abuts against the inner wall of the fixed seat 201. The force plate 2041 is fixedly set at the middle position of the lifting plate 203. The movable rod 204 is located outside the fixed seat 201, and a spring is provided between the force plate 2041 and the outer wall of the fixed seat 201; the top block 2042 is fixedly installed on the movable rod 204 inside the fixed seat 201, and the top block 2042 is adjacent to the shaft 2032. The top block 2042 has a wedge-shaped structure, and the top blocks 2042 on the four sets of movable rods 204 all face the shaft 2032; the fixed seat 201 is provided so that the mounting mechanism 1 can be installed on the car through the fixed seat 201; the overlapping platform 2011 is provided to provide support for the lifting plate 203; the baffle 202 is provided to limit the mounting mechanism 1 in the fixed seat 201 and allow the lifting plate 203 to move up and down in the fixed seat 201 along the baffle 202; A telescopic block 2021 is provided to support the lifting plate 203 when it is pushed to the upper end of the baffle 202, preventing it from falling back or tilting. A connecting rod 2031 is provided, which, by engaging with the insertion hole 103, allows the installation mechanism 1 to be inserted into the lifting plate 203. A shaft 2032 is provided, which, by pushing the shaft 2032 with the top block 2042, can lift the lifting plate 203 upward. A movable rod 204 is provided, with a force-bearing plate 2041 and a top block 2042 respectively at both ends of the movable rod 204. When the force-bearing plate 2041 is subjected to external force, the movable rod 204 pushes the top block 2042, causing the top block 2042 to move against the shaft 2032, thereby lifting the lifting plate 203.

[0040] This application provides a lifting plate 203 inside the fixed base 201, allowing the cover 101 containing the battery module 106 to be mounted on the lifting plate 203. The lifting plate 203 is then placed on the mounting platform 2011. Inside the fixed base 201, four sets of movable rods 204 with force plates 2041 are provided, with the wedge-shaped top blocks 2042 on the movable rods 204 facing the shaft 2032 at the lower end of the lifting plate 203. During normal use, the baffle 202 limits the installation mechanism 1, preventing the installation mechanism 1 from moving within the fixed base 201 due to vehicle movement. When the location where the battery module 106 is mounted on the vehicle is impacted, the lifting plate 203 pushes the top blocks 2042 to move via the connecting rods 2031. The top blocks 2042 then lift the lifting plate 203 and the installation mechanism 1 together via the shaft 2032. This allows the installation mechanism 1 to slide and collapse along the direction of force when impacted, thus avoiding direct impact.

[0041] The specific usage and function of this embodiment are as follows:

[0042] In this invention, such as Figures 1 to 9As shown, two sets of covers 101 are symmetrically spliced ​​together, with ear plates 104 fitting together. A rod 1071 at the bottom of the side plate 107 passes through the ear plates 104 on the same side of both sets of covers 101, thus limiting and fixing the two sets of covers 101. Inside each set of covers 101, multi-stage cylinders 1021 are used to insert stiffening plates 1022, allowing the stiffening plates 1022 to be installed in both horizontal and vertical directions. Rubber rings at the contact points between the stiffening plates 1022 and the multi-stage cylinders 1021 provide a fixing function. A carrier plate 105 is placed inside the lower cover 101, with its left and right sides aligned with the stiffening plates 1021. With 22 phases in contact, the battery module 106 is installed on the upper end of the carrier plate 105. A limiting rod 1051 passes through the connecting holes 1061 on both sides of the carrier plate 105 and the battery module 106 to fix the battery module 106 to the carrier plate 105. Then, the cover plate 1011 is fastened to both ends of the cover 101 to seal both sides of the assembled cover 101. After the mounting mechanism 1 is assembled, it is placed on the fixing seat 201 to be fixed inside the car, so that the insertion hole 103 below the lower end of the cover 101 engages with the connecting rod 2031 on the lifting plate 203 inside the fixing seat 201, lifting... The four corners of the lifting plate 203 rest on the overlapping platforms 2011 at the four corners of the fixed base 201, and the outer side contacts the baffle 202. During normal use, the baffle 202 limits the installation mechanism 1 to prevent it from moving within the fixed base 201. When the position where the car battery module 106 is installed is impacted, the impact force acts on the force plate 2041 and pushes the top block 2042 to move through the movable rod 204. Since the top block 2042 is a wedge-shaped structure, it slides along the conical shaft 2032 at the bottom of the lifting plate 203, lifting the lifting plate 203 and the installation mechanism 1 as a whole, so that the installation mechanism 1 is subjected to... Upon impact, the docking rod 2031 will break under lateral shear force, causing the mounting mechanism 1 to slide and collapse in the direction of force, thus avoiding direct impact. At the same time, when the lifting plate 203 is pushed to the upper end of the baffle 202, the telescopic block 2021 inside the baffle 202 supports the lifting plate 203 to prevent it from falling back or tilting. When the car is impacted, the vehicle will automatically cut off the power output of the hydrogen fuel cell and close all valve ports on the battery module 106. It will also cooperate with the cover 101 to detach from the fixed seat 201 to avoid the impact and prevent hydrogen leakage.
