Description

Technical Field

[0001] This application relates to the field of batteries, and more particularly to a battery housing, a battery, and a vehicle. Background Technology

[0002] Battery packs provide the energy needed to drive vehicles and hold a special place in new energy electric vehicles. They typically consist of modules made up of multiple battery cells, which are then arranged within a battery casing to form the entire battery pack. The energy density, safety, and lifespan of the battery pack are key factors determining the performance of an electric vehicle.

[0003] Structural adhesives are commonly used in battery pack assembly to enhance the connection strength and sealing between components. However, the flowability of the structural adhesive before curing on both sides of the module can lead to uneven distribution, affecting not only the connection effect but also potentially weakening the overall structural strength of the battery pack. Especially in large battery packs, improper use of structural adhesives can pose serious safety hazards. Therefore, designing a device that can effectively limit the flow of structural adhesive on both sides of the battery pack module and improve the overall structural strength of the battery pack is of great significance. Utility Model Content

[0004] The purpose of this application is to provide a battery housing, a battery, and a vehicle.

[0005] According to a first aspect of the embodiments of this application, a battery housing is provided, the battery housing comprising:

[0006] The main housing includes an installation space for mounting battery cells.

[0007] The blocking part is spaced apart from the installation space, and the blocking part includes a first blocking unit and a second blocking unit. The first blocking unit is connected to the main housing. The end of the first blocking unit away from the main housing is rotatably connected to the second blocking unit, and the second blocking unit can be rotatably disposed towards the installation space.

[0008] A traction unit is connected to the side of the second blocking unit near the mounting space, and is used to turn the second blocking unit toward the mounting space.

[0009] It should be noted that the traction part here can be driven by the weight of the battery cell during installation, pulling the second blocking unit from the inside to the installation space and thus abutting against the side of the battery cell. Alternatively, it can be manually pulled by the user to abut against the side of the battery cell. As long as the second blocking unit is pulled from the inside to the installation space, it is within the scope of protection of this application. The blocking part can be a baffle, cover, etc., and its material can be metal or plastic. The first blocking unit and the second blocking unit are rotatably connected, either by a pivot or a hinge. Of course, the first blocking unit 210 and the second blocking unit can also have other connection methods, as long as they are rotatably connected, they are within the scope of protection of this application.

[0010] Based on the above configuration, when the battery cell is installed into the installation space, the traction unit pulls the second blocking unit, causing it to adhere to the outside of the battery cell, thus forming a sealed space between the blocking unit and the battery cell. The structural adhesive located between the battery cell and the battery casing is squeezed out from the side during battery cell installation. At this time, the first blocking unit of the blocking unit first blocks the structural adhesive, preventing it from flowing out from the side and restricting its flow to a vertical direction. When the structural adhesive flows to the top, the second blocking unit blocks its overflow from above. That is, the structural adhesive is confined within this sealed space. This prevents the structural adhesive from flowing to other locations, thus maintaining the cleanliness of the casing interior. Furthermore, due to the blocking unit's obstruction, the adhesive slowly flows back, resulting in a more even distribution of the structural adhesive at the bottom of the casing, thereby enhancing the connection strength and sealing of each component. After the structural adhesive solidifies, it allows the first and second blocking units of the blocking unit to be directly and integrally fixed to the battery cell, thus surrounding the battery cell and providing lateral protection.

[0011] In some embodiments, the traction section includes a traction unit located in the installation space;

[0012] The battery cell can be driven by the traction unit to rotate the second blocking unit toward the installation space so as to abut against the battery cell.

[0013] Based on the above configuration, during the descent of the battery cell, it can press down on or hook onto the traction unit, thereby causing the second blocking unit to rotate towards the installation space. Finally, the second blocking unit abuts against the side of the battery cell. This configuration utilizes the descent of the battery cell to complete the rotation of the second blocking unit, reducing installation steps and thus improving installation efficiency.

[0014] In some embodiments, the number of blocking portions is multiple, and at least two of the second blocking units of the blocking portions are connected by the traction portion, and the traction portion is at least partially located within the installation space;

[0015] The battery cell can be driven by the traction unit to rotate the second blocking unit toward the installation space so as to abut against the battery cell.

[0016] That is, when the traction unit connects to multiple second blocking units, it passes through the installation space. When the battery cell descends, it can press down on the traction unit located in the installation space, thereby causing the traction unit and the second blocking units located outside the installation space to rotate into the installation space and come into contact with the battery cell. This process is simple and convenient, and multiple second blocking units can be flipped at once, thus greatly improving assembly efficiency. In addition, when the traction unit connects to multiple second blocking units, it can maintain a certain angle for the second blocking units from the beginning, making the second blocking units easier to flip.

[0017] In some embodiments, a receiving space is included between the first blocking unit and the mounting space, the battery housing includes a guide portion connected to the first blocking unit and disposed in the receiving space, the guide portion being used to guide the battery cell to move and be disposed in the mounting space.

[0018] Based on the above settings, the battery cell can be guided into the predetermined position by the guide part, so that the battery cell can better fit with the battery box, and the volume reserved for structural adhesive on both sides is nearly the same, thus enhancing the airtightness.

[0019] In some embodiments, the height of the guide portion gradually decreases from the first blocking unit toward the installation space, and the height of the guide portion at the end near the installation space is greater than 0 cm.

[0020] Specifically, the height of the guide section at the end closest to the installation space can be 1cm, 2cm, 5cm, 10cm, 15cm, 20cm, or 30cm.

[0021] Based on the above setup, a step is formed at one end of the installation space. When the battery cell slides down to the bottom of the step, it will be limited by the steps on both sides, thereby further preventing the battery cell from shifting away from the installation space.

[0022] In some embodiments, the first blocking unit and the second blocking unit are connected by a rotating shaft, and the second blocking unit can be rotated along the rotating shaft.

[0023] The second blocking unit can be dragged and rotated by the traction unit via the rotating shaft, and since the rotating shaft connects the first blocking unit and the second blocking unit respectively, the connection between the first blocking unit and the second blocking unit can be further guaranteed.

[0024] In some embodiments, the height of the blocking part in the vertical direction is greater than or equal to 1 cm and less than or equal to 50 cm.

[0025] This design prevents material waste in the blocking section and ensures that the second blocking unit is completely fixed to the battery cell. For example, the vertical height of the blocking section can be set to 1cm, 2cm, 3cm, 4cm, 5cm, 6cm, 7cm, 8cm, 9cm, 10cm, 15cm, 20cm, 30cm, 40cm, or 50cm.

[0026] In some embodiments, the blocking portion further includes a shielding unit disposed at the connection between the first blocking unit and the second blocking unit, so as to close the connection.

[0027] Based on the above configuration, the shielding unit seals the connection between the first blocking unit and the second blocking unit, thereby preventing structural adhesive from overflowing from the connection between the first blocking unit and the second blocking unit, further ensuring the airtightness of the structure and keeping the box clean.

[0028] In some embodiments, the blocking unit can be compressed, wherein the blocking unit is compressed when the second blocking unit is located at one end away from the mounting space, and stretched when the second blocking unit is located at one end close to the mounting space.

[0029] Based on the above settings, damage to the blocking unit can be avoided, which in turn allows for a better fit to the connection structure of the first and second blocking units, making it more durable and thus increasing the overall lifespan and durability of the battery box.

[0030] According to a second aspect of the embodiments of this application, a battery is provided, the battery including the battery housing described in any of the above embodiments.

[0031] According to a third aspect of the embodiments of this application, a vehicle is provided, the vehicle including the battery described in the above embodiments.

[0032] The beneficial technical effects of the technical solutions provided in this application are:

[0033] The system comprises a main housing, a blocking section, and a traction section. The main housing includes an installation space. The blocking section includes a first blocking unit and a second blocking unit. The first blocking unit is connected to the main housing. The end of the first blocking unit facing away from the main housing is rotatably connected to the second blocking unit, and the second blocking unit is rotatably positioned towards the installation space. The traction section is connected to the side of the second blocking unit closest to the installation space and is used to turn the second blocking unit towards the installation space.

[0034] Based on the above configuration, when the battery cell is installed into the installation space, the traction unit pulls the second blocking unit, causing it to adhere to the outside of the battery cell, thus forming a sealed space between the blocking unit and the battery cell. The structural adhesive located between the battery cell and the battery casing is squeezed out from the side during battery cell installation. At this time, the first blocking unit of the blocking unit first blocks the structural adhesive, preventing it from flowing out from the side and restricting its flow to a vertical direction. When the structural adhesive flows to the top, the second blocking unit blocks its overflow from above. That is, the structural adhesive is confined within this sealed space. This prevents the structural adhesive from flowing to other locations, thus maintaining the cleanliness of the casing interior. Furthermore, due to the blocking unit's obstruction, the adhesive slowly flows back, resulting in a more even distribution of the structural adhesive at the bottom of the casing, thereby enhancing the connection strength and sealing of each component.

[0053] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0055] New energy vehicles are mainly composed of components such as battery packs, electric motors, power electronic controllers, on-board chargers, thermal management systems, and intelligent control systems.

[0056] The battery pack provides the energy needed to drive the vehicle. It typically consists of modules of multiple battery cells arranged within a battery casing to form the entire battery pack. The energy density, safety, and lifespan of the battery pack are key factors determining the performance of an electric vehicle. The electric motor converts the electrical energy from the battery into mechanical energy to drive the wheels. Depending on the design, it can be an AC asynchronous motor or a permanent magnet synchronous motor. The choice of electric motor affects the vehicle's acceleration and top speed. The power electronics controller, including components such as inverters and converters, regulates the current and voltage output from the battery to meet the needs of the electric motor. It also manages the regenerative energy recovery process during braking, converting some kinetic energy back into electrical energy to charge the battery. The on-board charger converts external power (such as AC power from a household outlet or public charging station) into DC power to charge the battery. Its efficiency and power level directly affect the charging speed. The thermal management system ensures that the battery, electric motor, and power electronics components operate within suitable temperature ranges, preventing overheating that could lead to efficiency degradation or damage. This typically involves a coolant circulation system or an air cooling system. The intelligent control system integrates multiple sensors and software algorithms to monitor and adjust the status of these systems in real time, ensuring the safe, stable, and efficient operation of the vehicle. For example, it optimizes charging strategies by monitoring the battery status or dynamically adjusts the output power of the electric motor based on driving conditions.

[0057] All of these components are closely interconnected. The battery pack supplies power to the electric motor and other electrical systems. The electric motor directly drives the vehicle forward and works with the power electronic controller to achieve precise speed control and energy recovery. The on-board charger allows the vehicle to obtain energy from the grid to replenish the battery. The thermal management system protects critical components from extreme temperatures and ensures the normal operation of the overall system. The intelligent control system coordinates the work of all components, improving the user experience while ensuring driving safety.

[0058] The aforementioned battery pack is the heart of an electric vehicle and holds a special position in new energy electric vehicles. During the battery pack assembly process, specifically when arranging the cells within the battery box, structural adhesives are often used to enhance the connection strength and sealing between components. However, the flowability of the structural adhesive before curing on both sides of the module can lead to uneven distribution, affecting not only the connection effect but also potentially weakening the overall structural strength of the battery pack. Especially in large battery packs, improper use of structural adhesive can lead to serious safety hazards, thereby putting the entire vehicle at risk. Therefore, designing a device that can effectively limit the flow of structural adhesive on both sides of the battery pack module and improve the overall structural strength of the battery pack is of great significance.

[0059] This application provides a battery comprising a battery cell 20 and a battery housing 10, wherein the battery cell 20 is disposed within an installation space 110 of the battery housing 10. This battery is used in a vehicle and provides energy to the vehicle to drive its movement.

[0060] refer to Figure 1 , Figure 2 as well as Figure 3 As shown, where Figure 1 This represents the state in which the battery housing 10 and the battery cell 20 are in contact. Figure 2 and Figure 3 This represents the state where the battery housing 10 is not engaged with the battery cell 20. The battery housing 10 includes a main housing 100, a blocking portion 200, and a traction portion 300. The main housing 100 includes a mounting space 110 for mounting the battery cell 20. The blocking portion 200 is spaced apart from the mounting space 110 and includes a first blocking unit 210 and a second blocking unit 220. The first blocking unit 210 is connected to the main housing 100, and the end of the first blocking unit 210 facing away from the main housing 100 is rotatably connected to the second blocking unit 220, which is rotatably positioned towards the mounting space 110. The traction portion 300 is connected to the side of the second blocking unit 220 near the mounting space 110 and is used to turn the second blocking unit 220 towards the mounting space 110. (Reference) Figure 2 As shown, the second blocking unit 220 faces outward and is pulled by the traction unit 300. (Reference) Figure 1 As shown, the second blocking unit 220 is tractioned by the traction unit 300 and rotates to the mounting space 110 and fits against the outside of the battery cell 20.

[0061] It should be noted that the traction part 300 here can be driven by the weight of the battery cell 20 during installation, pulling the second blocking unit 220 from the inside to the installation space 110, and then abutting against the side of the battery cell 20. Alternatively, it can be manually pulled by the user to abut the second blocking unit 220 against the side of the battery cell 20. As long as the second blocking unit 220 is pulled from the inside to the installation space 110, it is within the scope of protection of this application. The blocking part 200 can be a baffle, cover, etc., and its material can be metal or plastic. The first blocking unit 210 and the second blocking unit 220 are rotatably connected, which can be a shaft connection or a hinge connection. Of course, the first blocking unit 210 and the second blocking unit 220 can also have other connection methods, as long as they are rotatably connected, they are within the scope of protection of this application.

[0062] Based on the above configuration, when the battery cell 20 is installed into the installation space 110, the traction unit 300 pulls the second blocking unit 220, causing the second blocking unit 220 to adhere to the outside of the battery cell 20, thereby forming a sealed space between the blocking unit 200 and the battery cell 20. The structural adhesive located between the battery cell 20 and the battery casing 10 is squeezed and overflows from the side during battery cell 20 installation. At this time, the first blocking unit 210 of the blocking unit 200 first blocks the structural adhesive, preventing it from flowing out from the side and restricting its flow to a vertical direction. When the structural adhesive flows to the top, the second blocking unit 220 blocks the overflow of the structural adhesive from above. That is, the structural adhesive is confined within this sealed space. This prevents the structural adhesive from flowing to other locations, thus maintaining the cleanliness of the casing interior. Furthermore, due to the blocking effect of the blocking unit 200, the adhesive slowly flows back, resulting in a more even distribution of the structural adhesive at the bottom of the casing, thereby enhancing the connection strength and sealing of each component. Furthermore, after the structural adhesive solidifies, it can directly fix the first blocking unit 210 and the second blocking unit 220 of the blocking part 200 and the battery cell 20 together, thereby making the blocking part 200 surround the battery cell 20 and form lateral protection for the battery cell 20.

[0063] In one embodiment, reference Figure 2 , Figure 3 as well as Figure 4 As shown, the traction unit 300 includes a traction unit 310 located in the mounting space 110; the battery cell 20 can be driven by the traction unit 310 to rotate the second blocking unit 220 toward the mounting space 110 so as to abut against the battery cell 20. That is, part of the structure of the traction unit 300 is arranged at the position where the battery cell 20 is arranged.

[0064] Based on the above configuration, during the descent of the battery cell 20, it can press down on or hook onto the traction unit 310, thereby causing the second blocking unit 220 to rotate toward the installation space 110. Finally, the second blocking unit 220 abuts against the side of the battery cell 20. This configuration, where the second blocking unit 220 is flipped simply by the descent of the battery cell 20, reduces installation steps and improves installation efficiency.

[0065] In one embodiment, reference Figure 1 , Figure 2 as well as Figure 3As shown, there are multiple blocking parts 200, and at least two blocking parts 200 have second blocking units 220 connected by a traction part 300. The traction part 300 is at least partially located within the mounting space 110. The battery cell 20 can be driven by the traction unit 310 to rotate the second blocking unit 220 towards the mounting space 110 so that it abuts against the battery cell 20. It should be noted that the number of blocking parts 200 can be two, three, four, etc., as long as the traction part 300 connecting the blocking parts 200 is at least partially located within the mounting space 110, it is within the protection scope of this application.

[0066] That is, when the traction unit 300 connects multiple second blocking units 220, it passes through the mounting space 110. When the battery cell 20 descends, it can press down on the traction unit 310 located in the mounting space 110, thereby causing the traction unit 300 and the second blocking units 220 located outside the mounting space 110 to rotate towards the mounting space 110 and abut against the battery cell 20. This process is simple and convenient, and multiple second blocking units 220 can be flipped at once, thus greatly improving assembly efficiency. Furthermore, refer to... Figure 2 and Figure 3 As shown, when the traction unit 300 is connected to multiple second blocking units 220, the second blocking units 220 can maintain a certain angle from the beginning, making the second blocking units 220 easier to flip.

[0067] Because the battery cell 20 will have a slight deviation when it falls, the battery cell 20 cannot fall completely into the installation space 110, which in turn causes the volume of the structural adhesive on both sides of the battery cell 20 to be different, further affecting the sealing of the package and the force on both sides of the battery cell 20.

[0068] refer to Figure 2 and Figure 6 As shown, a receiving space 120 is included between the first blocking unit 210 and the installation space 110. The battery box 10 is provided with a guide part (not shown in the figure), which is connected to the first blocking unit 210 and is disposed in the receiving space 120. The guide part is used to guide the battery cell 20 to move and be disposed in the installation space 110.

[0069] Based on the above settings, the battery cell 20 can be guided into the predetermined position by the guide part, so that the battery cell 20 can better match the battery box 10, and the volume reserved for structural adhesive on both sides is nearly the same, thereby enhancing the airtightness.

[0070] In one embodiment, the height of the guide portion gradually decreases from the first blocking unit 210 toward the mounting space 110, and the height of the guide portion near the mounting space 110 is greater than 0 cm. Specifically, the height of the guide portion near the mounting space 110 can be 1 cm, 2 cm, 5 cm, 10 cm, 15 cm, 20 cm, or 30 cm.

[0071] Based on the above configuration, a step is formed at one end of the installation space 110. When the battery cell 20 slides to the bottom of the step, it will be limited by the steps on both sides, thereby further preventing the battery cell 20 from shifting away from the installation space 110.

[0072] In one embodiment, reference Figure 4 and Figure 5 As shown, the first blocking unit 210 and the second blocking unit 220 are connected by a rotating shaft, and the second blocking unit 220 can be rotated along the rotating shaft.

[0073] The second blocking unit 220 can be dragged and rotated by the traction unit 300 via the rotating shaft. Since the rotating shaft connects the first blocking unit 210 and the second blocking unit 220 respectively, the connection between the first blocking unit 210 and the second blocking unit 220 can be further guaranteed.

[0074] The inventors discovered that when the height of the blocking part 200 is too low, the structural adhesive easily flows outward across the blocking part 200, thus failing to achieve its blocking function. At the same time, when the height of the blocking part 200 is too high, it will cause material waste in the blocking part 200 and prevent the second blocking unit 220 from contacting the structural adhesive, resulting in the second blocking unit 220 and the battery cell 20 not being completely fixed together.

[0075] In this application, the vertical height of the blocking portion 200 is set to be greater than or equal to 1 cm and less than or equal to 50 cm. This setting prevents material waste in the blocking portion 200 and ensures that the second blocking unit 220 and the battery cell 20 are completely fixed together. For example, the vertical height of the blocking portion 200 can be set to 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, 15 cm, 20 cm, 30 cm, 40 cm, or 50 cm.

[0076] Because the first blocking unit 210 and the second blocking unit 220 are connected by a rotating shaft, there will be a gap between them, and structural adhesive will overflow from this gap. Especially when the second blocking unit 220 rotates, the structural adhesive will overflow from this gap more easily.

[0077] In one embodiment, the blocking part 200 further includes a shielding unit (not shown in the figure), which is disposed at the connection between the first blocking unit 210 and the second blocking unit 220 to make the connection closed. It should be noted that the shielding unit here can be made of elastic plastic, rubber, etc., as long as it can rotate with the second blocking unit 220 and form a sealed space so that the structural adhesive does not overflow, it is within the scope of protection claimed in this application.

[0078] Based on the above configuration, the shielding unit seals the connection between the first blocking unit 210 and the second blocking unit 220, thereby preventing structural adhesive from overflowing from the connection between the first blocking unit 210 and the second blocking unit 220, further ensuring the airtightness of the structure and the cleanliness of the enclosure.

[0079] Furthermore, in one embodiment, the blocking unit can be compressed. When the second blocking unit 220 is located at the end opposite to the mounting space 110, the blocking unit is compressed; when the second blocking unit 220 is located at the end close to the mounting space 110, the blocking unit is stretched.

[0080] Based on the above settings, damage to the blocking unit can be avoided, and the connection structure of the first blocking unit 210 and the second blocking unit 220 can be better adapted, making it more durable, thereby increasing the overall lifespan and durability of the battery box 10.

[0081] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
