Detailed Embodiments

[0031] The following further describes the implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0032] As Figures 1 to 5 shown, the present utility model provides a battery box, including:

[0033] A box body 100, the box body 100 includes an outer plate 102 and an inner plate 104, and the outer plate 102 and the inner plate 104 enclose an installation space for installing a battery pack, and at least one of the outer plate 102 and the inner plate 104 is made of a transparent material;

[0034] An installation part 106, installed on the outer plate 102, and the installation part 106 is adapted to be connected to a target position to install the box body 100 at the target position.

[0035] According to the battery box provided by the embodiment of the present utility model, through the application of the transparent material, maintenance personnel can directly observe the state of the battery pack, timely discover and handle potential problems, thereby avoiding safety accidents caused by battery failures. At the same time, this design also simplifies the daily maintenance process and improves work efficiency. The modular structure design enables the battery box to be customized according to actual needs, meeting the usage requirements in different scenarios. In addition, the convenient design of the installation part 106 also improves the installation efficiency and usage flexibility of the battery box. In summary, the overall design of the battery box enables maintenance personnel to easily master the state information of the battery pack through the application of the transparent material; the modular design and convenient installation method make maintenance personnel more handy during use.

[0036] Please continue to refer to Figures 1 to 5 , the box body 100 is composed of an outer plate 102 and an inner plate 104, and at least one of the plates is made of a transparent material. The innovation point of this design is that it allows maintenance personnel to directly observe the state of the internal battery pack without opening the box body 100, such as the power indication, whether there are signs of abnormal heating or damage, etc. The selection of the transparent material not only improves the visualization degree of the product, but also facilitates daily maintenance and fault troubleshooting, improving safety and convenience. The box body 100 forms an installation space through the enclosure of the outer plate 102 and the inner plate 104. This modular design makes the structure of the box body 100 more flexible, facilitating the adjustment of the size and shape according to actual needs. At the same time, the modular design is also convenient for subsequent upgrades and maintenance, such as replacing damaged plate parts or adjusting the internal layout, etc.

[0037] The installation part 106 is directly installed on the outer side plate 102 and is designed with a connection structure adapted to different target positions. This design makes the installation process of the battery box more simple and fast. Without complex installation tools or steps, it can be easily fixed at the required position. In addition, the universal design of the installation part 106 also improves the applicable range of the battery box and can be widely applied to various occasions requiring battery power supply.

[0038] Thus, for the battery box provided by the embodiment of the present utility model, the application of the transparent material makes the internal state of the battery box clear at a glance, reducing potential safety hazards and unnecessary maintenance workload caused by the inability to directly observe. At the same time, quickly identifying the problem area also speeds up the fault handling speed and improves the stability and reliability of the overall system.

[0039] According to an embodiment of the present utility model, the outer side plate 102 includes:

[0040] An outer vertical plate 108;

[0041] A first mounting plate 110, installed on the inner side of the outer vertical plate 108. A first flanging 112 is formed at the edge of the first mounting plate 110 facing away from the outer vertical plate 108.

[0042] A second mounting plate 114, along the height direction of the outer vertical plate 108, the second mounting plate 114 is located below the first mounting plate 110 and the second mounting plate 114 is installed on the inner side of the outer vertical plate 108. A second flanging 116 is formed at the edge of the second mounting plate 114 facing away from the outer vertical plate 108.

[0043] As Figure 1 shown, in an embodiment of the present utility model, the structure of the outer side plate 102 is further refined and optimized to enhance its overall strength and installation flexibility.

[0044] The outer vertical plate 108 serves as the main support structure of the outer side plate 102. The outer vertical plate 108 provides the basic outline and support framework for the entire box body 100.

[0045] The first mounting plate 110 is designed and installed on the inner side of the outer vertical plate 108, that is, on the side facing the battery pack. This layout not only increases the strength of the outer side plate 102 but also provides a stable foundation for the battery. In particular, a first flanging 112 is formed at the edge of the first mounting plate 110 facing away from the outer vertical plate 108. This design not only enhances the structural strength of the first mounting plate 110 but also prevents the battery from falling off the first mounting plate 110.

[0046] Along the height direction of the outer vertical plate 108, the second mounting plate 114 is arranged below the first mounting plate 110 and is also mounted on the inner side of the outer vertical plate 108. This layered design makes the outer plate 102 have stronger structural layering and load-bearing capacity. Similar to the first mounting plate 110, the edge of the second mounting plate 114 facing away from the outer vertical plate 108 also forms a second flanging 116. This design also helps to enhance the structural stability of the second mounting plate 114 and can also prevent the battery from falling off the second mounting plate 114.

[0047] Through the above design, the outer plate 102 in this embodiment not only has sufficient strength and stiffness to support and protect the battery pack, but also improves the structural connection strength through the design of the first flanging 112 of the first mounting plate 110 and the second flanging 116 of the second mounting plate 114, and also avoids the falling off of the battery.

[0048] In the embodiment of the present utility model, the layered mounting plate design with flanging significantly enhances the overall strength and stiffness of each mounting plate, enabling the box body 100 to better resist external impacts and vibrations and protecting the safety of the internal battery pack. The design of the first flanging 112 and the second flanging 116 helps to prevent the battery from falling off. Moreover, the structure of the layered mounting plates can provide more flexible possibilities for adjusting the mounting space for different sizes and types of battery packs, and also facilitates subsequent maintenance and upgrade work.

[0049] According to an embodiment of the present utility model, a third flanging 118 is formed at the top of the outer plate 102, and the mounting portion 106 is mounted at the lower end of the third flanging 118.

[0050] As Figure 1 and Figure 2 shown, in an embodiment of the present utility model, a third flanging 118 is provided at the top of the outer plate 102. The setting of the third flanging 118 not only enhances the strength of the top edge of the outer plate 102, but also provides a more stable and convenient position for the installation of the mounting portion 106.

[0051] Specifically, the third flanging 118 is the length of the downward extension of the top edge of the outer plate 102, and its shape and size are determined according to actual needs, but the main purpose is to increase the structural strength of the top edge and provide an additional mounting surface.

[0052] The mounting portion 106, as a key component connecting the battery box to the target position, is mounted at the lower end of the third flanging 118. This mounting method ensures a firm connection between the mounting portion 106 and the outer plate 102, and also improves the stability and reliability of the overall structure.

[0053] Through the design of the third flanging 118, the installation part 106 can fit more closely on the outer plate 102, reducing the risk of loosening or falling off caused by improper installation. In addition, the third flanging 118 can also play a role in waterproofing and dustproofing to a certain extent, further protecting the safety of the installation part 106 and the internal components of the battery box.

[0054] The design of the third flanging 118 enables the installation part 106 to be installed more firmly on the outer plate 102, improving the stability and safety of the entire battery box. The third flanging 118 also provides a clear installation position and a stable installation foundation for the installation part 106, simplifying the installation process and improving the installation efficiency.

[0055] According to an embodiment of the present utility model, a rolling member 120 is provided between the installation part 106 and the third flanging 118.

[0056] As Figure 4 and Figure 5 shown, in an embodiment of the present utility model, in order to further improve the connection flexibility and installation convenience between the installation part 106 and the outer plate 102 (especially the third flanging 118), the rolling member 120 is specifically provided.

[0057] The rolling member 120 is arranged between the installation part 106 and the third flanging 118, and its specific form can be a ball, a roller, a rolling column, etc., and a suitable type and specification are selected according to the actual application scenario and load requirements. The function of the rolling member 120 is to provide rolling friction instead of sliding friction when the installation part 106 moves or adjusts its position relative to the third flanging 118, thereby greatly reducing the resistance and wear generated during the installation process.

[0058] By introducing the rolling member 120, the installation part 106 can be installed more easily and accurately to the target position, and it is also convenient for subsequent adjustment and disassembly work. In addition, the rolling member 120 helps to absorb and disperse the vibration and impact generated during the installation process, protecting the overall structure of the installation part 106 and the battery box from damage.

[0059] The design of the rolling member 120 significantly reduces the frictional resistance between the installation part 106 and the third flanging 118, making the installation process smoother and more efficient. The rolling member 120 enables the installation part 106 to flexibly adjust its position and direction within a certain range to adapt to different installation requirements and environmental changes. By providing rolling friction instead of sliding friction, the rolling member 120 effectively reduces the wear and stress concentration phenomenon generated during the installation process, extending the service life of the battery box. The rolling member 120 also helps to absorb and disperse the vibration and impact generated during the installation process, improving the overall stability and reliability of the battery box.

[0060] According to an embodiment of the present utility model, a chute is formed at the lower end of the third flanging 118, an installation groove is formed on the installation part 106, and the rolling member 120 is installed between the installation groove and the chute.

[0061] In an embodiment of the present utility model, the lower end of the third flanging 118 is designed to have a structure with a chute, and a corresponding installation groove is formed on the installation part 106. The designs of these two grooves match each other, jointly providing precise positioning and stable support for the installation of the rolling member 120.

[0062] Specifically, the chute is located at the lower edge of the third flanging 118, and its shape and size are customized according to the specifications and installation requirements of the rolling member 120. The main function of the chute is to guide the rolling member 120 to move along a predetermined trajectory, and at the same time ensure that the rolling member 120 will not fall off or deviate from the direction during the installation process.

[0063] On the other hand, the installation groove on the installation part 106 is designed to accommodate the rolling member 120. The shape and depth of the installation groove match the rolling member 120 to ensure that the rolling member 120 can be stably installed in the installation groove and can roll freely in the chute.

[0064] When the installation part 106 is connected to the third flanging 118, the rolling member 120 is placed between the installation groove and the chute. As the installation part 106 moves or adjusts its position, the rolling member 120 rolls in the chute, thereby realizing a flexible connection between the installation part 106 and the third flanging 118. This design not only simplifies the installation process but also improves the stability and reliability of the connection.

[0065] The designs of the chute and the installation groove provide precise positioning for the rolling member 120, ensuring an accurate connection between the installation part 106 and the third flanging 118. The rolling member 120 is stably installed between the installation groove and the chute and can withstand a certain load and impact force, providing stable support for the installation part 106.

[0066] According to an embodiment of the present utility model, the installation part 106 includes:

[0067] A first lapping part 122 and a second lapping part 124, the first lapping part 122 and the second lapping part 124 abut against the lower end of the third flanging 118;

[0068] A first lifting lug 126 and a second lifting lug 128, the first lifting lug 126 is connected to both ends of the first lapping part 122, the second lifting lug 128 is connected to both ends of the second lapping part 124, and the first lifting lug 126 and the second lifting lug 128 are connected to the target position.

[0069] Such asFigure 2 As shown, in an embodiment of the present utility model, the structural design of the mounting portion 106 has been further refined and optimized. The mounting portion 106 mainly includes key components such as a first lapping portion 122, a second lapping portion 124, a first lifting lug 126, and a second lifting lug 128. These components work together to ensure that the battery box can be stably and conveniently mounted at the target position.

[0070] Specifically, the first lapping portion 122 and the second lapping portion 124 are the main parts of the mounting portion 106. The first lapping portion 122 and the second lapping portion 124 can closely abut against the lower end of the third flanging 118. This abutting method not only enhances the connection strength between the mounting portion 106 and the outer plate 102 but also ensures the stability of the battery box during the installation process. The shapes and sizes of the first lapping portion 122 and the second lapping portion 124 are customized according to the specific structure of the third flanging 118 to ensure that they can perfectly match and closely fit.

[0071] To further fix the mounting portion 106, the first lifting lug 126 and the second lifting lug 128 are respectively connected to both ends of the first lapping portion 122 and the second lapping portion 124. The first lifting lug 126 and the second lifting lug 128, as connecting members, are used to firmly connect the mounting portion 106 to the target position. The specific forms and quantities of the first lifting lug 126 and the second lifting lug 128 can be adjusted according to the actual installation requirements to ensure the firmness and reliability of the connection. In practical applications, these lifting lugs may be connected to the corresponding components at the target position through bolts, screws, or other fasteners.

[0072] Through this design, the first lapping portion 122 and the second lapping portion 124 can not only achieve a tight connection with the outer plate 102 but also be firmly fixed to the target position through the first lifting lug 126 and the second lifting lug 128.

[0073] Through the close abutment of the first lapping portion 122 and the second lapping portion 124 with the third flanging 118 and the firm connection of the first lifting lug 126 and the second lifting lug 128 with the target position, the installation strength and stability of the battery box are jointly enhanced. By designing a reasonable mounting portion 106 and lifting lug structure, the installation process is simplified, the installation difficulty is reduced, and the installation efficiency is improved.

[0074] According to an embodiment of the present utility model, the ends of the first lifting lug 126 and the ends of the second lifting lug 128 are away from each other, and mounting holes 132 are provided at the ends of the first lifting lug 126 and the ends of the second lifting lug 128.

[0075] As Figure 1 and Figure 2As shown, in an embodiment of the present utility model, the ends of the first lifting lug 126 and the ends of the second lifting lug 128 are designed to be away from each other. This layout helps to disperse the stress points during installation, enabling the installation part 106 to more evenly disperse stress when subjected to external forces, thereby enhancing the stability of the overall structure.

[0076] In addition, for ease of installation and fixation, mounting holes 132 are provided at the ends of the first lifting lug 126 and the ends of the second lifting lug 128. The mounting holes 132 can be customized according to the connecting parts (such as bolts, screws, etc.) at the target position to ensure a perfect match between the mounting holes 132 and the connecting parts. During installation, by passing these connecting parts through the mounting holes 132 and tightening them, a firm connection between the installation part 106 and the target position can be achieved.

[0077] The design of the ends of the first lifting lug 126 and the second lifting lug 128 being away from each other, together with the setting of the mounting holes 132, improves the connection stability between the installation part 106 and the target position. This design enables the installation part 106 to more effectively resist deformation and displacement when subjected to external forces. The setting of the mounting holes 132 simplifies the installation process, allowing installers to complete the installation work faster and improving the installation efficiency.

[0078] According to an embodiment of the present utility model, the box body 100 includes a first sub-box and a second sub-box, and a mounting flange is formed on the docking surface of the first sub-box and the second sub-box.

[0079] In an embodiment of the present utility model, the box body 100 is divided into two parts, namely a first sub-box and a second sub-box. This split design not only facilitates manufacturing, transportation, and installation, but also improves the flexibility and maintainability of the battery box.

[0080] More importantly, on the docking surface of the first sub-box and the second sub-box, a mounting flange is designed. The mounting flange is designed to closely fit the sub-box docking surface and is fixed by bolts, screws, or other fasteners to ensure a firm connection between the first sub-box and the second sub-box.

[0081] The design of the mounting flange not only enhances the connection strength between the sub-boxes, but also provides reliable sealing performance, preventing the battery pack or other sensitive components inside the battery box from being interfered with or damaged by the external environment. In addition, the mounting flange also facilitates subsequent maintenance and repair work. When it is necessary to open or disassemble the battery box, the first sub-box and the second sub-box can be easily separated by loosening the fasteners.

[0082] The design of the mounting flange enhances the connection strength between the first sub - box and the second sub - box, making the structure of the entire battery box more stable and reliable. The tight fit between the mounting flange and the butt joint surface of the sub - box, along with the fixing effect of the fasteners, jointly provide reliable sealing performance and protect the safety of the internal components of the battery box. The split - type design makes the battery box more flexible and convenient during transportation and installation, reducing transportation costs and installation difficulties.

[0083] According to an embodiment of the present invention, it further includes a cover plate 130, and the cover plate 130 is detachably connected to the top of the box body 100.

[0084] As Figure 1 and Figure 2 shown, in an embodiment of the present invention, in order to further enhance the practicability and convenience of the battery box, a detachable cover plate 130 is added to the top of the box body 100.

[0085] When installing, maintaining, or overhauling the internal components of the battery box, maintenance personnel can easily remove or install the cover plate 130 without performing complex disassembly operations on the entire battery box. This design not only improves work efficiency but also reduces the operation difficulty, enabling non - professional personnel to perform simple maintenance work when necessary.

[0086] To ensure the sealing between the cover plate 130 and the box body 100, a sealing strip can be set on the contact surface between the cover plate 130 and the box body 100 or other sealing measures can be adopted. In this way, even under harsh environmental conditions, it can effectively prevent external moisture, dust, or other impurities from entering the interior of the battery box, thereby protecting the internal components from damage.

[0087] The detachable cover plate 130 design makes the installation, maintenance, and overhaul of the internal components of the battery box more convenient and fast. By taking sealing measures, it ensures a tight connection between the cover plate 130 and the box body 100, effectively preventing interference and damage from the external environment.

[0088] According to an embodiment of the present invention, the battery pack includes a plurality of batteries, and the plurality of batteries are electrically connected to each other.

[0089] As Figure 2 shown, in an embodiment of the present invention, the battery pack is composed of a plurality of batteries, and these batteries are electrically connected to each other to form an integrated power supply unit.

[0090] First of all, by increasing the number of batteries, the total capacity and power supply ability of the battery pack can be significantly improved, thus meeting the requirements of higher power and longer battery life;

[0091] Secondly, the parallel or series connection of multiple storage batteries can achieve flexible adjustment of voltage and current to meet the requirements of different loads and application scenarios.

[0092] In addition, the redundant design of multiple storage batteries can also improve the reliability and fault tolerance of the system. Even if some storage batteries fail, other storage batteries can still continue to work to ensure the stable operation of the system.

[0093] In terms of electrical connection, various methods such as conductive sheets, wires, and connectors can be used to connect the storage batteries. These connection methods need to have good electrical conductivity and stability to ensure the smooth transmission of current between the storage batteries and reduce energy loss and safety hazards.

[0094] The parallel or series connection of multiple storage batteries significantly increases the total capacity and power supply ability of the battery pack, meeting the requirements of higher power and longer battery life. By adjusting the connection method between the storage batteries, the voltage and current output of the battery pack can be flexibly adjusted to meet the requirements of different loads and application scenarios.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. However, such modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
