Description

TECHNICAL FIELD

[0001] The present application relates to the field of new energy vehicles, in particular to a multi-module detachable battery box. BACKGROUND

[0002] The existing battery box technology generally adopts an integrated design, that is, multiple battery packs are integrated in the entire battery box. This design has a long design life and high design mileage, which can meet most application requirements. However, as the battery is used, especially in the industry such as online car-hailing, the battery pack will cause performance degradation due to attenuation. Although the overall design life of the battery box is long, the battery will be severely attenuated after about three years of use, resulting in the need for repair or replacement. In this case, the structural design of the traditional battery box has significant limitations.

[0003] The main defect of the traditional integrated battery box is its non-detachable structure. This structure makes it necessary to replace the entire battery box when repair or replacement is needed, regardless of the degree of attenuation of the battery packs in the battery box. Due to the high cost of replacing the battery box, unnecessary resources are wasted and economic burden is incurred. In fact, in most cases, the attenuation speed of each battery pack in the battery box is not the same, and usually only part of the battery pack needs to be replaced, while the other battery packs can still be used. However, since the battery box is designed in an integrated manner, it cannot be replaced or repaired locally, which leads to the replacement of the entire battery box, increasing the operating cost, especially in the online car-hailing industry that requires high frequency of battery replacement, the problem is particularly prominent.

[0004] In addition, due to the inconsistent attenuation speed of the battery packs, different battery packs in the battery box may be in different attenuation stages. The existing integrated battery box design fails to take this into account, so it cannot achieve rapid repair and local replacement, resulting in low repair efficiency. More seriously, due to the complicated and time-consuming replacement process of the entire battery box, the vehicle downtime is too long, affecting the operating efficiency.

[0005] Therefore, it is particularly important to develop a multi-module detachable battery box technology. CONTENT OF THE INVENTION

[0006] The purpose of the present application is to at least overcome at least one deficiency of the prior art, provide a multi-module detachable battery box, which uses a modular structure and can replace different battery packs according to their attenuation conditions, reducing the need for overall replacement, thereby effectively saving costs, improving repair efficiency, shortening downtime, and improving the economic benefits of operation.

[0007] To achieve the above object, the application discloses a multi-module detachable battery box, which comprises a body and a battery module, wherein the bottom surface of the body is concavely provided with a plurality of mounting slots for mounting and fixing the battery module, the battery module is detachably locked in the mounting slot and seals the mounting slot, meeting the needs of overall sealing use of the battery box; the mounting slot is provided with a ventilation interface and a power transmission interface, and the body is provided with a ventilation flow channel or a ventilation pipeline connected with each ventilation interface; the battery module comprises a shell and a battery pack composed of a plurality of batteries in the shell, and the shell is provided with an extended ventilation connector and an electrical connector, wherein the ventilation connector is connected with the ventilation interface and the power transmission interface is connected with the electrical connector in the battery module inserted into the mounting slot.

[0008] In some embodiments, the battery box has a detachable outer bottom plate covering and protecting the bottom end of the battery module and the bottom surface of the body.

[0009] In some embodiments, the shell of the battery module is provided with a ring-shaped sealing strip for sealing cooperation with the mounting slot.

[0010] In some embodiments, the rigid side surface of the shell of the battery module is provided with a rubber layer for tightly cooperating the battery module with the mounting slot and absorbing the vibration impact on the battery module during driving to ensure the stable connection and cooperation of the battery module with the mounting slot.

[0011] In some embodiments, the top surface of the body is provided with a fire-retardant and heat-insulating layer.

[0012] Compared with the prior art, the application has at least one of the following beneficial effects:

[0013] 1. Reducing replacement cost: Since the battery box adopts modular design, partial replacement can be performed according to the attenuation of different battery packs, and the entire battery box does not need to be replaced, thereby significantly reducing maintenance and replacement cost and reducing unnecessary resource waste.

[0014] 2. Improving maintenance efficiency: The modular design makes the disassembly and replacement of the battery module more convenient, thereby improving the maintenance efficiency. For the case of uneven battery attenuation, only the attenuated part can be replaced, avoiding the complex process of overall replacement and reducing the maintenance time.

[0015] 3. Shortening downtime: The technology optimizes the disassembly and installation process of the battery module, making the replacement work more efficient and shortening the downtime of the vehicle, which helps to improve the operation efficiency, especially suitable for the industry such as online car-hailing which needs high-frequency battery replacement.

[0016] 4. The structure stability is enhanced: the battery module and the body are tightly matched through the ring-shaped sealing strip and the rubber layer, which ensures the stable installation of the module, absorbs the vibration impact, improves the stability and safety of the battery box during driving, and prolongs the service life of the battery box.

[0017] The above-listed benefits are not exhaustive of all advantages. Other potential benefits and detailed technical implementations will be further disclosed in the embodiments or other description sections of the present application. BRIEF DESCRIPTION OF DRAWINGS

[0025] Referring to the drawings Figure 1 And 2 In order to more fully demonstrate the specific embodiments of the utility model, the following describes an embodiment of a multi-module detachable battery box in combination with the structure, design principle, working principle and mutual cooperation relationship of each component.

[0026] The body 1 is the main structure of the battery box, and a plurality of mounting slots 3 are concavely arranged on the bottom surface of the body 1. The mounting slots 3 are evenly distributed on the bottom of the body 1, ensuring that the battery modules 2 can be evenly installed and distributed to bear loads. A ventilation interface 4 and a power transmission interface 5 are pre-set in each mounting slot 3, so that the battery modules 2 can be effectively ventilated and connected to power when installed. The design of the mounting slot 3 takes into account the need for modular replacement, and the inside of the slot is made of high-strength material to ensure that it still has good structural strength and sealing performance during multiple disassembly and assembly processes.

[0027] The battery module 2 is composed of a solid shell, and a plurality of battery units are built into the shell. The battery units are arranged in a specific arrangement to optimize space utilization and heat dissipation effect. The shell 2 is provided with an extended ventilation connector 4 and an electrical connector 5. The ventilation connector 4 is connected to the ventilation interface 4 of the body 1 to realize air circulation inside the battery module, preventing the battery from overheating. The electrical connector 5 is connected to the power transmission interface 5 of the body 1 to ensure that the battery module can stably output power. The material of the shell 2 is a high-strength lightweight alloy, which not only ensures the mechanical strength of the battery module, but also effectively reduces the weight of the overall battery box.

[0028] At the connection between the battery module 2 and the body 1, a ring-shaped sealing strip 7 is installed on the sealing surface of the shell 2. Through the sealing cooperation between the ring-shaped sealing strip 7 and the mounting slot 3, the sealing performance of the entire battery box is ensured, preventing the influence of the external environment on the battery pack. At the same time, the side surface of the shell 2 is covered with a rubber layer 8. This design not only tightly matches the battery module 2 with the mounting slot 3 to prevent loosening, but also absorbs the shock impact generated during vehicle driving through the rubber layer 8, ensuring the stability and safety of the battery module 2 under dynamic conditions.

[0029] The outer bottom plate 6 is made of wear-resistant and anti-skid material and serves as a bottom protection device for the battery box 1. It can effectively cover and protect the bottom end of the battery module 2 and the bottom surface of the body 1. The outer bottom plate 6 is designed to be detachable, which facilitates quick removal of the outer bottom plate 6 when maintenance or replacement of the battery module 2 is required, reduces operation time, and improves maintenance efficiency.

[0030] The top surface of the body 1 is covered with a fire-retardant and heat-insulating layer 9 made of high-efficiency fire-retardant material. It can provide excellent heat-insulating effect in high-temperature environment and protect the battery module 2 from external temperature fluctuations. At the same time, the fire-retardant and heat-insulating layer 9 can effectively prevent the spread of flames in the event of a fire or other accidents, thereby improving the safety performance of the entire battery box 1.

[0031] In actual application, for example, in the online car-hailing industry, the battery box 1 of the vehicle needs to frequently replace part of the battery module 2 to cope with the problem of uneven battery degradation. When the performance of a certain battery module 2 decreases, the technician only needs to disassemble the outer bottom plate 6, remove the battery module 2 that needs to be replaced, and then install the new battery module 2 into the corresponding mounting groove 3. Due to the design of the ventilation joint 4 and the power connection joint 5, the new module 2 can quickly connect with the ventilation interface 4 and the power transmission interface 5 of the body 1, and the entire replacement process is efficient and simple. This not only significantly reduces the maintenance and replacement cost, but also greatly shortens the downtime of the vehicle and improves the operation efficiency.

[0032] In addition, the multi-module detachable design makes the battery box 1 have greater flexibility when facing different types or specifications of battery modules 2. The operator can choose appropriate battery modules 2 for replacement or upgrade according to actual needs without replacing the entire battery box 1. This design not only prolongs the service life of the battery box 1, but also provides convenience for the upgrade and iteration of future battery technology.

[0033] In summary, through the specific description of the embodiment, it can be seen that the multi-module detachable battery box 1 is optimized in terms of structural design, material selection, and working principle. It not only solves many deficiencies in the prior art, but also exhibits significant economic benefits and operational convenience in actual application, especially suitable for industry scenarios that require high-frequency battery replacement.

[0034] Although exemplary embodiments of the present disclosure have been described, it will be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the protection scope of the present disclosure defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
