Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-2 Describes a vehicle 100 according to an embodiment of the present utility model.

[0026] like Figure 1 As shown, a vehicle 100 according to a first aspect embodiment of the present invention includes a vehicle body 1 and at least one battery pack 2.

[0027] Specifically, at least one opening 11 is formed on the vehicle body 1. The battery pack 2 is disposed at the opening 11, and the battery pack 2 is connected to the vehicle body 1, and the battery pack 2 and the vehicle body 1 are integrated as one unit. The above-mentioned "at least one" means that there is at least one battery pack 2, and there can be two or more.

[0028] For example, refer to Figure 1 Two openings 11 are formed on the vehicle body 1, meaning that the vehicle body 1 has a hollowed-out structure, which provides an installation position for the battery pack 2, so as to fix the battery pack 2 to the vehicle body 1. Moreover, the hollowed-out body connects the battery pack 2 to the vehicle body 1, and the bottom of the battery pack 2 acts as the roof, so that the battery pack 2 is fixed to the vehicle body on all sides. The battery pack 2 and the vehicle body 1 form an integrated structure, which effectively improves the stability of the battery pack 2 installation structure.

[0029] This design allows the battery pack 2 to be directly integrated with the vehicle body 1, eliminating the need for a bracket structure. This results in a high degree of integration and significant weight reduction for the vehicle 100, which is beneficial for its lightweight and integrated development. Furthermore, the battery pack 2 and vehicle body 1 form an integral structure, effectively improving the torsional stiffness of the vehicle 100, reducing the probability of deformation under stress, enhancing the safety and durability of the battery system, and extending the battery pack 2's lifespan. Simultaneously, the opening 11 in the vehicle body 1 effectively reduces the weight of the vehicle 100 itself, lowering energy consumption during operation and extending its driving range. Additionally, the battery pack 2 is easy to install and remove, with a simple manufacturing process, reducing installation difficulty and improving production efficiency. It also lowers the overall height of the vehicle 100, making it suitable for operation on roads with varying conditions (such as height restrictions).

[0030] According to the present invention, in the vehicle 100, the battery pack 2 is directly integrated with the vehicle body 1, eliminating the need for a bracket structure. This results in a high degree of integration and significant weight reduction in the vehicle 100, which is beneficial for the lightweight and integrated development of the vehicle 100. Furthermore, the battery pack 2 forms an integral structure with the vehicle body 1, effectively improving the torsional stiffness of the vehicle 100, reducing the probability of deformation under stress, enhancing the safety and durability of the battery system, and extending the service life of the battery pack 2. Simultaneously, the opening 11 in the vehicle body 1 effectively reduces the weight of the vehicle 100 itself, reducing power consumption during operation and extending the driving range. Additionally, the battery pack 2 is easy to install and remove, with a simple manufacturing process, reducing installation difficulty and improving the production efficiency of the vehicle 100.

[0031] According to some embodiments of this utility model, refer to Figure 4 The battery pack 2 is connected to the vehicle body 1 through a connecting structure 3, which is arranged around the circumference of the battery pack 2.

[0032] For example, in Figure 4In the example, multiple connecting structures 3 are formed along the circumference of the battery pack 2, at its bottom, and on the vehicle body 1 for connecting the battery pack 2 to the vehicle body 1. When the vehicle 100 is a bus, due to the large weight of the bus itself and the battery pack 2, to avoid deformation caused by local overload of the vehicle body 1, the connecting structures 3 on the battery pack 2 and the vehicle body 1 achieve multi-point fixation. This allows the weight of the battery pack 2 to be evenly distributed to the load-bearing structures such as the roof crossbeams and longitudinal beams, preventing excessive stress at a single point from causing sheet metal dents or frame deformation of the vehicle body 1. Furthermore, it also prevents the battery pack 2 from cracking due to localized stress concentration, thereby extending the service life of the battery pack 2 and the structural stability of the vehicle body 1, reducing the maintenance cost of the vehicle 100. In addition, the above connection method makes the battery pack 2 easy to install and remove, reducing the difficulty of disassembling and installing the battery pack 2, thus reducing the operation and maintenance cost of the battery pack 2.

[0033] According to some embodiments of this utility model, refer to Figure 4 There are multiple connecting structures 3, which are arranged at intervals along the circumference of the battery pack 2. In the description of this utility model, "multiple" means two or more.

[0034] exist Figure 4 In the example, along the length of the battery pack 2, eight connecting structures 3 are formed on the upper and lower sides of the battery pack 2, and along the width of the battery pack 2, five connecting structures 3 are formed on the left and right sides of the battery pack 2, with the multiple connecting structures 3 arranged at intervals. For example, when the battery pack 2 is used in a bus, due to the large weight and passenger capacity of the bus, the amplitude of vibration and bumps during driving is also large. The battery pack 2 needs to withstand continuous longitudinal and lateral impact forces. Multiple connecting structures 3 allow the battery pack 2 to be fixed to the vehicle body 1 at multiple points, thereby evenly distributing the weight and dynamic load of the battery pack 2 onto the vehicle body 1. This avoids excessive force at a single point, which could cause deformation of the connecting structure 3 or even detachment of the battery pack 2, ensuring the stability of the connection between the battery pack 2 and the vehicle body 1. This improves the safety and stability of the vehicle 100 during driving and reduces the maintenance cost of the vehicle 100. In addition, it can also improve the adaptability of the battery pack 2, so that it can be flexibly applied to buses of different models or layouts, expanding the application scenarios. It should be noted that the number of connecting structures 3 can be set according to the actual situation, and no specific limitation is made here.

[0035] According to some embodiments of this utility model, refer to Figure 2 and Figure 4 The connection structure 3 includes a vehicle body connection structure 31 and a battery pack connection structure 32. Specifically, the vehicle body connection structure 31 is disposed on the vehicle body 1. The battery pack connection structure 32 is disposed on the battery pack 2, and the battery pack connection structure 32 cooperates with the vehicle body connection structure 31 to realize the connection between the battery pack 2 and the vehicle body 1.

[0036] For example, refer to Figure 2 and Figure 4 The connection structure 3 includes a vehicle body connection structure 31 and a battery pack connection structure 32. Furthermore, the positions and shapes of the vehicle body connection structure 31 and the battery pack connection structure 32 are correspondingly arranged, enabling a stable connection between the battery pack 2 and the vehicle body 1. This arrangement effectively improves the connection stability between the battery pack 2 and the vehicle body 1, thereby preventing deformation caused by localized overload of the vehicle body 1 and preventing shell cracking of the battery pack 2 due to localized stress concentration. This extends the service life of the battery pack 2 and enhances the structural stability of the vehicle body 1, reducing vehicle maintenance costs. In addition, it reduces the difficulty of connecting the battery pack to the vehicle body 1, improves installation efficiency, and lowers installation and maintenance costs.

[0037] According to some embodiments of this utility model, refer to Figures 1-4 The vehicle body connection structure 31 is a vehicle body connection hole 311 formed on the vehicle body 1, and the battery pack connection structure 32 is a battery pack connection hole 321 formed on the battery pack 2. The connection structure 3 further includes a fastener (not shown in the figure), which cooperates with the vehicle body connection hole 311 and the battery pack connection hole 321 to realize the connection between the battery pack 2 and the vehicle body 1.

[0038] For example, refer to Figure 2 The vehicle body connection structure 31 is a vehicle body connection hole 311 formed on the vehicle body 1, and the battery pack connection structure 32 is a battery pack connection hole 321 formed on the battery pack 2. The vehicle body connection hole 311 and the battery pack connection hole 321 can be used to connect the battery pack 2 to the vehicle body 1 using fasteners (such as bolts). This design effectively reduces the difficulty of connecting the battery pack 2 to the vehicle body 1 and improves the installation efficiency of the battery pack 2. In addition, the high operating intensity of buses requires regular maintenance of the battery pack 2, and the above connection method effectively improves the operating efficiency of maintenance personnel and shortens downtime.

[0039] Optionally, the vehicle body connection hole 311 and the battery pack connection hole 321 can be connected to the vehicle body 1 from top to bottom, i.e., the fastener first passes through the battery pack connection hole 321 and then through the vehicle body connection hole 311. Alternatively, a top-to-bottom fixing method can be achieved by back-welding a nut. It should be noted that the vehicle body connection hole 311 and the battery pack connection hole 321 can be configured according to actual conditions.

[0040] According to some embodiments of this utility model, refer to Figure 2 and Figure 4 The battery pack 2 and the vehicle body 1 are positioned by the positioning structure 4.

[0041] For example, refer to Figure 2 and Figure 4Multiple positioning structures 4 are formed on both the battery pack 2 and the vehicle body 1, and the shapes and positions of the positioning structures 4 on the battery pack 2 and the vehicle body 1 correspond accordingly. This enables precise installation of the battery pack 2, reduces installation difficulty, improves installation accuracy and efficiency, and thus increases the production yield of the vehicle 100. Furthermore, the positioning structures 4 provide positioning points for the maintenance or replacement of the battery pack 2, shortening maintenance time. In addition, the positioning structures 4 and the connecting structures 3 work together to form a rigid connection structure 3, which can evenly transfer the weight and impact load of the battery pack 2 to the vehicle body 1, avoiding cracks in the battery pack 2 caused by localized stress concentration and extending the service life of the vehicle 100. Furthermore, it can limit the displacement of the battery pack 2, protect the integrity of the battery pack 2 and the connecting structures 3, ensure the driving stability of the vehicle 100, and reduce the failure rate of the vehicle 100.

[0042] According to some embodiments of this utility model, refer to Figure 2 and Figure 4 The positioning structure 4 includes a vehicle body positioning structure 41 and a battery pack positioning structure 42. Specifically, the vehicle body positioning structure 41 is located on the vehicle body 1. The battery pack positioning structure 42 is located on the battery pack 2, and the battery pack positioning structure 42 cooperates with the vehicle body positioning structure 41 to achieve positioning of the battery pack 2 and the vehicle body 1.

[0043] For example, refer to Figure 2 and Figure 4 The positioning structure 4 includes a vehicle body positioning structure 41 mounted on the vehicle body 1 and a battery pack positioning structure 42 mounted on the battery pack 2. Through the cooperation of the vehicle body positioning structure 41 and the battery pack positioning structure 42, the battery pack 2 is positioned relative to the vehicle body 1. This configuration effectively improves the installation efficiency of the battery pack 2 and shortens the installation time. Furthermore, it enables precise positioning of the battery pack 2, forming a rigid connection structure 3 between the battery pack 2 and the vehicle body 1. This improves the torsional stiffness of the entire vehicle, reduces the stress deformation of the battery pack 2, enhances the safety and durability of the battery system, and ensures the vehicle's 100% driving stability.

[0044] According to some embodiments of this utility model, refer to Figure 2 and Figure 4 One of the vehicle body positioning structure 41 and the battery pack positioning structure 42 is formed as a positioning hole 411, and the other of the vehicle body positioning structure 41 and the battery pack positioning structure 42 is a positioning element 421. The positioning element 421 cooperates with the positioning hole 411 to realize the positioning of the battery pack 2 and the vehicle body 1.

[0045] For example, in Figure 2 and Figure 4In the example, the vehicle body positioning structure 41 is formed as a positioning hole 411, and the battery pack positioning structure 42 is formed as a positioning element 421. The number, shape, and position of the positioning holes 411 and the positioning elements 421 are matched, enabling the battery pack 2 to be precisely positioned with the vehicle body 1. This effectively improves the installation efficiency of the battery pack 2, shortens the installation time, and improves the overall vehicle assembly efficiency, thereby reducing the production cost of the vehicle 100. In addition, it can also improve the torsional stiffness of the entire vehicle, thereby reducing the stress deformation of the battery pack 2, improving the safety and durability of the battery system, and ensuring the driving stability of the vehicle 100.

[0046] Optionally, the vehicle body positioning structure 41 can be formed as a positioning element 421, and the battery pack positioning structure 42 can be formed as a positioning hole 411. The positioning element 421 and the positioning hole 411 can be set according to the actual situation.

[0047] According to some embodiments of this utility model, refer to Figure 2 and Figure 4 There are multiple positioning structures 4, which are located at the four corners of the battery pack 2.

[0048] For example, refer to Figure 2 and Figure 4 Four positioning structures 4 are located at the four corners of the battery pack 2. This arrangement forms a rectangular fixing structure at the four corners of the battery pack 2, which counteracts the torsional tendency of the vehicle body 1. By balancing the torsional torque through diagonal tension / thrust, it improves the overall torsional stiffness of the vehicle 100, reduces the torsional deformation of the battery pack 2's outer shell, thereby extending the service life of the battery pack 2 and the stability of the vehicle body 1, and reducing the maintenance cost of the vehicle 100. Furthermore, the positioning structures 4 at the four corners of the battery pack 2, through symmetrically distributed fixing points, form a stable support frame, offsetting the torque caused by inertial forces during cornering or sudden braking of the vehicle 100. This ensures uniform force distribution at the connection between the battery pack 2 and the vehicle body, reduces the load on individual fasteners, extends the service life of fasteners, ensures the long-term stability of the connection structure 31 between the battery pack 2 and the vehicle body, and improves the driving safety of the vehicle 100.

[0049] According to some embodiments of this utility model, refer to Figure 4 The battery pack 2 has a connector 22 located on one side of the battery pack 2 adjacent to the center of the vehicle body 1; and / or, the battery pack 2 and the vehicle body 1 are sealed together; and / or, the edge of the opening 11 is provided with a vehicle body beam 7.

[0050] For example, refer to Figure 4Two connectors 22 are located on the bottom of the battery pack 2, near the center of the vehicle body 1: a high-voltage connector 222 and a low-voltage connector 221. When the battery pack 2 is used in a bus, the core components of the bus, such as the vehicle control unit (VCU), motor controller, and charger, are mostly concentrated in the central area of ​​the vehicle body 1. When the connector 22 is near the center of the vehicle body 1, the high-voltage wiring harness and low-voltage signal lines between the battery pack 2 and the aforementioned core components can be significantly shortened, thereby reducing energy loss and signal transmission delay caused by line resistance, and improving energy utilization efficiency and control response speed. In addition, the battery pack 2 is a heavy-load component of the bus. Placing the connector 22 at the center of the vehicle body 1 allows the weight of the relevant wiring harness to be closer to the center of gravity of the vehicle 100, reducing the driving load caused by weight shift, which helps to improve the stability of the vehicle 100 and thus improve the driving safety of the vehicle 100. Moreover, the vibration amplitude at both ends of the bus body 1 is usually greater than that in the center area when the bus is in motion. The insertion interface 22 is located at the center of the bus body 1, which can reduce the wear and tear on the mechanical structure and electrical contact of the interface caused by long-term high-frequency vibration, reduce the probability of interface loosening and poor contact, ensure the stability of the performance of the battery pack 2, and thus extend the service life of the battery pack 2.

[0051] According to some embodiments of the present invention, the battery pack 2 and the vehicle body 1 are sealed together.

[0052] This configuration ensures a sealed connection between the battery pack 2 and the vehicle body 1, creating a physical barrier that effectively isolates external contaminants (such as moisture, dust, or corrosive substances). This guarantees the insulation and structural integrity of the internal circuitry of the battery pack 2, extends its lifespan, ensures the stability of the vehicle's power supply system, and improves driving safety and stability. Furthermore, it reduces the failure rate of the battery pack 2, thereby decreasing the frequency of cleaning and maintenance, and lowering maintenance costs. Additionally, it ensures the stability of the battery pack 2's performance, reduces the aging rate of the battery cells 23, and lowers the vehicle's maintenance costs.

[0053] According to some embodiments of this utility model, refer to Figure 1 and Figure 2 The edge of the opening 11 is provided with a body beam 7.

[0054] For example, refer to Figure 2 The body beam 7 is located at the edge of the opening 11, and includes a body crossbeam 71 and a body longitudinal beam 72. This enables a fixed connection between the battery pack 2 and the vehicle body 1, effectively improving the strength of the connection structure 3 and ensuring the stability of the battery pack 2 connection. Furthermore, the body beam 7 integrates the battery pack 2 with the vehicle body 1, making the battery pack 2 a part of the vehicle 100. This effectively improves the torsional stiffness of the vehicle 100, reduces the probability of deformation of the battery pack 2 under stress, enhances the safety and durability of the battery system, and extends the service life of the battery pack 2.

[0055] Optionally, the body beam 7 can be configured as a square tube beam structure, that is, the body beam 7 is a hollow profile with a square or rectangular cross section. This can reduce the weight of the body beam 7 while ensuring that the body beam 7 resists bending and torsional stress, thereby helping to reduce the weight of the body 1, which is conducive to the lightweight development of the vehicle 100, reducing the energy consumption of the vehicle 100, extending the driving range, and improving market competitiveness.

[0056] Optionally, the body beam 7 can also be configured as a sliding groove structure, that is, a sliding groove is provided on the body crossbeam 71 or the body longitudinal beam 72, and the battery pack 2 is inserted into the sliding groove by a slider, and locked with high-strength bolts after sliding into place. When the body beam 7 is configured as a sliding groove structure, it helps to reduce the installation difficulty of the battery pack 2 and the body 1 and improves the installation efficiency. At the same time, when the vehicle 100 collides, the slight displacement generated by the sliding groove can buffer the impact force on the battery pack 2, thereby protecting the safety of the battery pack 2 and improving the driving safety of the vehicle 100.

[0057] Specifically, the high-voltage connector 222 can transmit the high-voltage DC power stored in the battery pack 2 to high-voltage components such as the high-voltage power distribution unit (PDU) and drive motor (not shown in the figure), and then convert it into AC power through the motor controller (not shown in the figure) to drive the vehicle 100. The low-voltage connector 221 connects to modules such as the battery communication converter (BCC) and battery management controller (BMC) (not shown in the figure), and monitors the status of the battery pack 2 in real time by collecting data such as the voltage, temperature, and SOC (state of charge) of the battery pack 2, ensuring the stable operation of the vehicle 100.

[0058] According to some embodiments of this utility model, refer to Figure 4 A first seal 5 is provided between the battery pack 2 and the vehicle body 1, and the first seal 5 surrounds the connector 22. And / or, the vehicle body 1 is provided with a vehicle body 1 ventilation system (not shown), which includes a vehicle body 1 ventilation duct (not shown), and the wiring harness of the connector 22 is hidden within the vehicle body 1 ventilation duct. And / or, a second seal is provided between the battery pack 2 and the vehicle body 1, and the second seal surrounds the opening 11.

[0059] For example, in Figure 4In this example, a first seal 5 is provided at the connection point between the bottom of the battery pack 2 and the vehicle body 1 to ensure a seal between the battery pack 2 and the connector 22 of the vehicle body 1. This design effectively prevents water, dust, and foreign objects from clogging the connector 22, ensuring the stability of the electrical connection at the connector 22, maintaining battery range and safety, reducing the failure rate, and ensuring the stability of the vehicle 100 during operation. Furthermore, the first seal 5 can compensate for assembly gaps at the connector 22, thereby ensuring the stability of the electrical connection of the battery pack 2. In addition, it can buffer mechanical impacts, preventing physical damage to the connector 22 and extending the service life of the battery pack 2.

[0060] Meanwhile, the first seal 5 is arranged around the connector 22, forming a closed-loop sealing structure along the edge of the battery pack 2. This arrangement creates a closed-loop protection between the battery pack 2 and the vehicle body 1, effectively preventing external dust, moisture, and foreign objects from clogging the connector 22, ensuring the stability of the electrical connection at the connector 22, and extending the service life of the battery pack 2. Furthermore, the surrounding first seal 5, while sealing, also enhances the stability of the electrical connection at the connector 22 through elastic support, preventing minor relative displacement between the plug and the housing caused by vibrations and bumps during vehicle operation, thus reducing wear. Moreover, it prevents loosening of the sealing structure due to displacement, maintaining a long-term sealing effect, ensuring the stability of the battery pack 2's performance, reducing the battery pack 2's failure rate, and improving market competitiveness.

[0061] According to some embodiments of the present invention, a vehicle body 1 air duct system (not shown in the figure) is provided on the vehicle body 1. The vehicle body 1 air duct system includes a vehicle body 1 air duct (not shown in the figure), and the wiring harness of the plug interface 22 is hidden inside the vehicle body 1 air duct.

[0062] For example, the vehicle body 1 is equipped with a vehicle body 1 air duct system. In this application, the battery pack 2 is installed on the top of the vehicle body 1, and the connector faces downward (i.e., towards the lower side in the height direction of the vehicle body 1), so that the wiring harness of the connector 22 can be hidden inside the vehicle body 1 air duct system. With this configuration, the vehicle body 1 air duct system can maintain ventilation, heat dissipation, or temperature balance inside the vehicle body 1 while also hiding the wiring harness of the connector 22 inside the vehicle body 1 air duct, thereby improving the space utilization of the vehicle body 1 and facilitating the integrated development of the vehicle 100.

[0063] According to some embodiments of this utility model, refer to Figure 4 A second seal (not shown) is provided between the battery pack 2 and the vehicle body 1, and the second seal is arranged around the opening 11.

[0064] For example, refer to Figure 4A second sealing groove 6 is provided around the circumference of the battery pack 2, allowing the second seal to be placed within the groove 6, thus achieving a sealed connection between the battery pack 2 and the vehicle body 1. Furthermore, the second sealing groove 6 and the second seal are arranged around the opening 11. This arrangement effectively prevents external contaminants from entering the battery pack 2 through the opening 11, ensuring the insulation and structural integrity of the internal circuitry of the battery pack 2, extending its service life, ensuring the stability of the vehicle 100's power supply system, and improving driving safety and stability. In addition, the second seal eliminates assembly gaps, buffers the impact force between the battery pack 2 and the vehicle body 1, reduces the probability of fatigue damage to battery pack 2 components (such as the base plate 24 and battery cells 23), extends the battery pack 2's service life, and reduces maintenance costs. Moreover, the cooperation between the second seal and the connecting structure 3 effectively improves the connection stability between the battery pack 2 and the vehicle body 1, thereby increasing the torsional stiffness of the vehicle 100, preventing cracks in the battery pack 2, ensuring the stability of the vehicle 100's power supply system, and ensuring the vehicle 100's driving stability. It should be noted that the second sealing groove 6 on the battery pack 2 can be one or multiple, and the number and structure of the second sealing groove 6 can be adjusted according to specific circumstances. No specific limitation is made here.

[0065] According to some embodiments of this utility model, refer to Figure 1 An opening 11 is formed on the top of the vehicle body 1.

[0066] For example, refer to Figure 1 An opening 11 is formed on the top of the vehicle body 1 (the upper side in the height direction of the vehicle 100) to facilitate the installation of the body beam 7 and achieve a stable connection with the battery pack 2. This design, with the opening 11 on the top of the vehicle body 1, helps reduce the weight of the vehicle body 1, achieving lightweight development of the vehicle 100, reducing power consumption during vehicle 100 operation, and extending the vehicle 100's driving range. Furthermore, it allows for stable installation of the battery pack 2 without the need for a battery pack 2 bracket, improving the integration and space utilization of the vehicle 100. In addition, the opening 11 allows the battery pack 2 to form an integrated structure with the vehicle body 1, effectively improving the stability of the battery pack 2 installation structure, increasing the torsional stiffness of the vehicle 100, reducing the probability of deformation of the battery pack 2 under stress, enhancing the safety and durability of the battery system, and extending the service life of the battery pack 2.

[0067] The battery pack 2 according to the second aspect of the present invention is applicable to the vehicle 100 according to the first aspect of the present invention.

[0068] The battery pack 2 according to this embodiment of the present invention is suitable for the aforementioned vehicle 100. It can be directly integrated with the entire vehicle, has a high degree of integration, and is also conducive to improving the lightweight effect of the vehicle 100, thereby reducing the energy consumption of electric vehicles and extending the driving range. Moreover, it can also improve the handling of the vehicle 100, thereby improving the driving safety and driver comfort of the vehicle 100 and enhancing its market competitiveness.

[0069] According to some embodiments of this utility model, refer to Figure 5 The battery pack 2 includes a battery cell 23, a base plate 24, a cover plate 25, a side beam 26, and a heat exchange device 27. Specifically, the base plate 24 is located at the bottom of the battery cell 23. The cover plate 25 is located at the top of the battery cell 23. The side beam 26 surrounds the outer periphery of the battery cell 23 and is connected to the base plate 24 and the cover plate 25. The heat exchange device 27 is located between at least one of the base plate 24 and the cover plate 25 and the battery cell 23.

[0070] For example, the battery pack 2 includes a battery cell 23. The battery cell 23 is the core unit for energy storage, conversion, and output, and directly determines the vehicle 100's range, power performance, charging speed, and safety reliability. The battery cell 23 has a base plate 24 at its bottom, a cover plate 25 at its top, and a side beam 26 on its outer periphery. The side beam 26 is connected to the base plate 24 and the cover plate 25. That is, the base plate 24, the cover plate 25, and the side beam 26 together constitute the "three-dimensional protective frame" of the battery cell 23.

[0071] Specifically, the base plate 24 is located at the bottom of the battery cell 23 (i.e., Figure 5 The lower side (indicated by arrow B) enables the weight-bearing capacity and bottom sealing of the battery cell 23, thereby preventing displacement, tilting, or even collision of the battery cell 23 during vehicle 100 operation (such as bumps, rapid acceleration / deceleration) or vibration. This avoids faults such as electrode breakage and wiring harness detachment caused by misalignment of the battery cell 23, ensuring the stability of the battery cell 23's performance and thus guaranteeing the stability of the vehicle 100's power supply system. The cover plate 25 is located on the top of the battery cell 23, that is, on the side of the bottom plate 24 furthest from the center of the vehicle body 1 (i.e., Figure 5 (The upper side indicated by arrow B) The cover plate 25 can prevent the top of the cell 23 from shifting laterally during vibration or impact, ensuring the stability of the cell 23 structure.

[0072] For example, refer to Figure 5Side beam 26 is located at the outer corner of the battery cell 23 and protrudes from the upper side of the vehicle body 1. The side beam 26 resists lateral vibrations, collisions, or lateral forces generated by the expansion of the battery cell 23 during vehicle operation, preventing the battery cell 23 from tipping over or deforming under lateral forces. Furthermore, the side beam 26 connects to the base plate 24 and the cover plate 25, forming a rigid frame that provides three-dimensional protection and isolation for the battery cell 23, ensuring the stability of its performance and thus guaranteeing the overall stability of the battery pack 2, extending its service life. In addition, the side beam 26 effectively improves the structural strength of the battery pack 2. When the battery pack 2 is a roof-mounted battery pack for a bus, it effectively improves the battery pack 2's resistance to impacts (such as foreign object impacts), thereby extending its service life.

[0073] In addition, the battery pack 2 also includes a heat exchange device 27, such as a cold plate, which is in direct contact with the battery cell 23. It uses a flowing liquid or other medium to control the temperature of the battery cell 23, improving heat dissipation efficiency, reducing the temperature difference between the battery cell 23 and the cell, preventing thermal failure, and ensuring the stability of the battery pack 2's performance. For example, the heat exchange device 27 can be placed only between the cover plate 25 and the battery cell 23, or it can be placed between the battery cell 23 and both the cover plate 25 and the base plate 24. The placement method needs to be selected based on the actual situation.

[0074] For example, refer to Figure 4 The battery pack 2 is also equipped with cooling pipes, and a cooling interface 29 is provided at the bottom of the battery pack 2. One end of the cooling pipe is connected to the cooling interface 29. The cooling pipe can be laid inside the bottom plate 24 of the battery pack 2, so that it can work together with the heat exchange device 27 to improve heat dissipation efficiency, reduce the temperature difference of the cells 23, prevent thermal failure, and ensure the stability of the performance of the battery pack 2.

[0075] Furthermore, the rigid frame formed by the base plate 24, cover plate 25, and side beams 26 can effectively resist external impact forces, while the heat exchange device 27 can achieve precise temperature control of the battery cell 23, ensuring the stability of the battery cell 23's performance. Through the synergistic effect of the base plate 24, cover plate 25, side beams 26, and heat exchange device 27, the cycle life and overall service life of the battery pack 2 are effectively extended, reducing the maintenance costs of the vehicle 100 and enhancing the vehicle 100's market competitiveness.

[0076] According to some embodiments of this utility model, refer to Figure 5 At least a portion of the side surface of the side beam 26 away from the bottom plate 24 is formed as a guide surface 261.

[0077] For example, refer to Figure 5The portion of the side beam 26 protruding from the top of the vehicle body 1 forms a guide surface 261. This design effectively guides the flow of liquids (such as rainwater), reducing the risk of corrosion or short circuits in the battery cells 23 caused by liquid accumulation, thereby ensuring the stability of the vehicle 100's electrical circuits, ensuring the vehicle 100's operational stability, and reducing maintenance costs. Furthermore, the guide surface 261 can also disperse impact loads. When the battery pack 2 is subjected to significant external forces (such as impacts from foreign objects), the guide surface 261 can evenly distribute the impact force throughout the entire side beam 26 structure, preventing stress concentration in localized areas (such as right-angle corners) that could lead to breakage, thus extending the battery pack 2's lifespan. Additionally, the guide surface 261 reduces airflow disturbance, lowers driving noise, and improves driver and passenger comfort.

[0078] Optionally, the airflow guide surface 261 can be arc-shaped, right-angled, curved, or other structures integrated with the vehicle body. The shape of the airflow guide surface 261 can be set according to the actual situation.

[0079] According to some embodiments of this utility model, refer to Figure 5 The guide surface 261 is an arc-shaped guide surface 261.

[0080] This design allows the arc-shaped guide surface 261 to facilitate rainwater drainage, enabling rainwater to accumulate on the top of the vehicle 100. This ensures that the battery cells 23 are not corroded by moisture, extending the service life of the battery pack 2, improving the stability of the vehicle 100's electrical system, and reducing maintenance costs. Furthermore, the arc-shaped side beam 26 can buffer external impacts, distributing external forces evenly across the entire battery pack 2. This reduces the direct transmission of external forces to core components such as the battery cells 23 inside the battery pack 2, lowering the risk of cell damage and short circuits, and extending the service life of the battery pack 2.

[0081] According to some embodiments of this utility model, refer to Figure 3 and Figure 5 The cover plate 25 is provided with a heat insulation component 251.

[0082] For example, refer to Figure 3 and Figure 5 The upper side of cover plate 25 (i.e. Figure 5 An insulation component 251 is located on the upper side (indicated by arrow B). This design eliminates the need for an additional outer cover for the battery pack 2, reducing its weight and consequently the overall weight of the vehicle 100, thus improving its maneuverability. Furthermore, the insulation component 251 reduces heat loss from the battery pack 2, ensuring uniform temperature distribution of the battery cells 23. This improves the balance of charging and discharging, extends the battery pack 2's lifespan, and guarantees the stability of the vehicle 100's electrical system.

[0083] According to some embodiments of this utility model, refer to Figure 3 and Figure 5 The insulation element 251 is provided on the surface of the cover plate 25 away from the battery cell 23. And / or, the insulation element 251 is provided on the surface of the cover plate 25 adjacent to the battery cell 23. And / or, the insulation element 251 is insulation cotton or insulation coating.

[0084] For example, the insulation component 251 is located on the upper side of the cover plate 25 (i.e. Figure 5 (The upper side indicated by the middle arrow B). This design effectively reduces the impact of ambient temperature fluctuations on the battery cell 23, maintaining a stable operating temperature and improving the stability of the battery pack 2's performance. Furthermore, the insulation component 251 reduces heat loss from the battery pack 2, resulting in more uniform cell temperature, thus improving the balance of charging and discharging and extending the battery pack 2's lifespan. Simultaneously, the insulation component 251 eliminates the need for an additional outer cover for the battery pack 2, reducing its overall weight and consequently the overall weight of the vehicle 100, improving its maneuverability.

[0085] Optionally, the insulation component 251 can be located on the underside of the cover plate 25, i.e., the side closer to the battery cell 23. This arrangement reduces the heat exchange rate at the connection between the battery cell 23 and the cover plate 25, minimizes the temperature difference between the battery cell 23, avoids uneven charging and discharging due to inconsistent temperatures, and extends the lifespan of the battery cell 23. Furthermore, it prevents external temperature changes from affecting the battery cell 23, avoiding sudden temperature rises and falls and ensuring the stability of the battery cell 23's performance. Additionally, the insulation component 251 can buffer mechanical impacts, protect the structure of the battery cell 23, ensure the stability of the battery pack 2's performance, and extend the battery pack 2's lifespan. It should be noted that the location of the insulation component 251 can be set according to actual conditions.

[0086] According to some embodiments of this utility model, refer to Figure 3 Insulation component 251 is insulation cotton or insulation coating.

[0087] For example, the insulation component 251 can be insulation cotton or insulation coating, and its thickness, shape, and color can be changed according to actual needs. This design improves the versatility of the battery pack 2 and expands its application scenarios. In addition, by selecting the material, thickness, and shape of the insulation component 251, it is beneficial to the lightweight development of the battery pack 2, thereby reducing the overall weight of the vehicle 100 and improving the vehicle 100's maneuverability.

[0088] According to some embodiments of this utility model, refer to Figure 5 The side beam 26 is equipped with reinforcing ribs 262.

[0089] This configuration, with the reinforcing ribs 262 on the side beam 26, strengthens the surrounding structure of the battery pack 2, significantly improving its structural strength and rigidity, reducing the risk of deformation, and extending its service life. Furthermore, by optimizing the arrangement of the reinforcing ribs 262, the structural strength of the battery pack 2 can be significantly improved, facilitating its lightweight development and thus reducing the overall weight of the vehicle 100, achieving lightweight vehicle development, improving vehicle handling, and reducing driving energy consumption. It should be noted that the structural shape of the reinforcing ribs 262 can be varied and should be set according to the actual situation.

[0090] According to some embodiments of this utility model, refer to Figure 3 The battery pack 2 has multiple lifting ports 28, which are arranged at intervals along the circumference of the battery pack 2.

[0091] For example, in Figure 3 In the example, the battery pack 2 has four lifting ports 28, which are evenly spaced along the outer periphery of the battery pack 2. This arrangement of multiple lifting ports 28 on the battery pack 2 allows for connection to lifting equipment such as cranes and forklifts, enabling the battery pack 2 to be smoothly lifted from the ground and installed on top of the vehicle 100. This improves the installation accuracy of the battery pack 2, reduces installation difficulty, and increases installation efficiency. Furthermore, it reduces damage to the vehicle body 1 structure during installation or maintenance, extending the service life of the vehicle 100.

[0092] According to some embodiments of this utility model, refer to Figure 3 Multiple lifting ports 28 are located along the length of the battery pack 2 (i.e., Figure 3 The two ends (in the direction indicated by the middle arrow C).

[0093] For example, refer to Figure 3 Four lifting ports 28 are symmetrically arranged at both ends of the battery pack 2 along its length. This symmetrical arrangement ensures that the lifting hooks of the hoisting equipment receive even force through the two lifting ports 28 during hoisting, preventing the battery pack 2 from tilting or swaying during the process, ensuring stability, and preventing damage to the battery pack 2. Furthermore, it reduces the difficulty of installation, inspection, and maintenance.
