Figure 2 This is a schematic diagram of the structure of the protective cover 20 provided in this embodiment of the utility model.

[0020] This embodiment provides a battery box structure, including a box body 10, a protective cover 20, and an antenna plate 30. Specifically, the box body 10 has an assembly opening 101 to facilitate the assembly of subsequent components. The protective cover 20 is made of plastic and is reliably connected to the edge of the assembly opening 101 in the box body 10 via a snap-fit ​​structure, ensuring both assembly firmness and ease of disassembly and maintenance. The antenna plate 30 is mounted on the protective cover 20 through an appropriate connection method. The protective cover 20 covers and closes the assembly opening 101, effectively protecting the internal components of the box body 10. Because the protective cover 20 is made of plastic, it will not cause electromagnetic interference to the signal reception of the antenna plate 30, ensuring that the antenna plate 30 can operate stably and normally. This structural design simplifies the composition of the battery box and is conducive to achieving integration and lightweight goals.

[0021] This technical solution, through the aforementioned innovative structural design, effectively addresses the technical problems in existing battery box structures, such as the antenna plate 30's susceptibility to interference from metal components, decreased signal reception performance, and the difficulty in balancing structural sealing and ease of maintenance. Firstly, the protective cover 20, made of plastic, avoids the shielding and interference of metal on the antenna plate 30's signal, improving the system's signal quality and communication stability. Secondly, the protective cover 20 is snap-fitted to the box body 10, significantly improving the sealing of the assembly port 101 and effectively preventing external factors such as dust and moisture from entering the box body 10, thereby enhancing the safety and lifespan of the internal components of the battery box. Furthermore, the snap-fit ​​connection facilitates the assembly and disassembly of the protective cover 20 and the antenna plate 30, greatly simplifying subsequent maintenance, repair, and antenna plate 30 replacement, thus improving product maintainability. Finally, the integrated installation of the antenna plate 30 and the protective cover 20 simplifies the structure, improves assembly efficiency, and contributes to the integration and lightweighting of the battery box structure. In summary, this technical solution, through reasonable structural design and material selection, achieves stable signal reception of the antenna board 30, reliable sealing of the enclosure 10, and ease of maintenance, significantly improving the overall performance of the battery box.

[0022] This embodiment provides a battery box structure, characterized in that the structure includes screws 40, which pass through an antenna plate 30 and are threadedly connected to a protective cover 20. Specifically, during the assembly of the battery box, the antenna plate 30 is first positioned at a predetermined installation position on the protective cover 20, aligning the mounting holes on the antenna plate 30 with the threaded holes on the protective cover 20. Subsequently, the screws 40 are passed through the mounting holes on the antenna plate 30 and screwed into the threaded holes on the protective cover 20, thereby securely mounting the antenna plate 30 onto the protective cover 20. The tightening of the screws 40 not only ensures a tight connection between the antenna plate 30 and the protective cover 20 but also facilitates subsequent disassembly and maintenance.

[0023] This technical solution, through a screw 40 threadedly connecting the antenna plate 30 to the protective cover 20, effectively solves the technical problems of poor installation stability, easy loosening, and inconvenient maintenance of the antenna plate 30 in existing battery box structures. Firstly, the screw 40 connection ensures reliable fixation between the antenna plate 30 and the protective cover 20, preventing displacement or loosening of the antenna plate 30 due to vibration or long-term use, thus guaranteeing the signal reception performance of the antenna plate 30 and the overall stability of the system. Secondly, the use of screws 40 for assembly simplifies the disassembly and replacement of the antenna plate 30, facilitating daily maintenance and future repairs, and improving the maintainability of the battery box structure. In summary, this technical solution, through the screw 40 threadedly connecting the antenna plate 30 to the protective cover 20, achieves a stable connection between the antenna plate 30 and the protective cover 20, improving assembly firmness and maintenance convenience, and significantly enhancing the overall performance and reliability of the battery box structure.

[0024] This embodiment provides a protective cover 20 structure for a battery box. The protective cover 20 includes a main body 21, a skirt 22, and a fastener 23, wherein the skirt 22 is disposed around the periphery of the main body 21. To facilitate assembly and disassembly, a notch 24 is provided on the skirt 22, and the fastener 23 is disposed at the notch 24 and connected to the skirt 22. Specifically, a certain gap is maintained between the fastener 23 and the side wall of the notch 24 to avoid structural interference. In use, the protective cover 20 is snapped together with the edge of the battery box 10 having an assembly opening 101 through the fastener 23. During assembly, the operator can align the fastener 23 of the protective cover 20 with the edge of the assembly opening 101 of the box 10 and press in a specific direction to achieve quick and secure assembly; if disassembly is required, the protective cover 20 can also be easily removed through the gap between the fastener 23 and the notch 24 of the skirt 22.

[0025] This technical solution addresses the problems of inconvenient assembly, poor sealing, and difficult maintenance associated with traditional protective covers 20. By setting a notch 24 in the skirt 22 and a latch 23 spaced apart from the skirt 22 at the notch 24, the assemblability and maintainability of the structure are significantly improved. First, the spacing design between the latch 23 and the side wall of the notch 24 in the skirt 22 makes it easier for the operator to manipulate the latch 23, enabling quick assembly and disassembly of the protective cover 20 and improving maintenance efficiency. Second, the snap-fit ​​connection between the latch 23 and the edge of the assembly port 101 of the housing 10 ensures a tight fit between the protective cover 20 and the housing 10, enhancing sealing performance and effectively preventing dust, moisture, and other external substances from entering the battery box, thus improving the safety and reliability of the battery box. In addition, this structure simplifies the overall manufacturing process of the protective cover 20, reduces assembly difficulty, and facilitates mass production. In summary, this technical solution, through reasonable structural innovation, solves the technical problems of difficult assembly, insufficient sealing, and inconvenient maintenance of the protective cover 20, achieving the technical effects of a robust structure, easy assembly, and efficient maintenance.

[0026] This embodiment provides an improved protective cover 20 structure. The protective cover 20 includes a main body 21, a stop 25, etc. The stop 25 is an annular structure, surrounding and fixedly disposed on the outer peripheral edge of the main body 21. During assembly, the stop 25 can overlap with the surface of the housing 10, so that an effective contact interface is formed between the protective cover 20 and the housing 10. Specifically, when installing the protective cover 20, the main body 21 of the protective cover 20 is aligned with the opening of the housing 10, and the stop 25 naturally covers and overlaps the surface of the housing 10, thereby forming a continuous contact band.

[0027] This technical solution effectively solves the problems of traditional protective covers 20 in terms of sealing and protection by setting a baffle 25 around the main body 21 on the outer periphery of the protective cover 20 and having it overlap the surface of the housing 10. First, the overlapping of the baffle 25 enhances the sealing between the protective cover 20 and the housing 10, effectively preventing external impurities such as dust and moisture from entering the housing 10, thus improving the protective performance and service life of the battery box. Second, the baffle 25 acts as a buffer and shock absorber on the surface of the housing 10, reducing damage to the protective cover 20 and the housing 10 caused by external impacts, and improving the safety and reliability of the structure. Furthermore, the overlapping structure of the baffle 25 optimizes the assembly tolerances between the protective cover 20 and the housing 10, ensuring a tight fit during installation and reducing assembly difficulty. In summary, this technical solution, by setting a baffle 25 around the main body 21 and overlapping the surface of the housing 10, achieves improved sealing, enhanced protection, and simplified assembly, significantly improving the structural performance of traditional protective covers 20.

[0028] This embodiment provides an assembly structure for a protective cover 20 with a limiting function. The protective cover 20 includes a main body 21 and a stop 25 surrounding the main body 21. A limiting groove 102 corresponding to the stop 25 is formed on the surface of the housing 10. When the protective cover 20 is installed, the stop 25 can be accurately embedded in the limiting groove 102, achieving effective positioning and limiting of the protective cover 20, so that the protective cover 20 is firmly attached to the housing 10. Specifically, the operator aligns the protective cover 20 with the housing 10, aligns the stop 25 with the limiting groove 102, and then gently presses the protective cover 20. The stop 25 is then smoothly accommodated in the limiting groove 102, ensuring that the protective cover 20 is installed in place and is not easily displaced.

[0029] This technical solution addresses the problems of misalignment, poor sealing, or detachment of traditional protective covers 20 during assembly. By setting a limiting groove 102 on the surface of the housing 10 and further housing the stop 25 within the limiting groove 102, the positioning accuracy and assembly stability of the protective cover 20 are effectively improved. On one hand, the cooperation between the stop 25 and the limiting groove 102 not only enables the protective cover 20 to be positioned quickly and accurately, preventing lateral or longitudinal sliding and enhancing the firmness of the connection between the protective cover 20 and the housing 10, but also improves the sealing performance of the structure by embedding the stop 25 within the limiting groove 102, further preventing external impurities such as dust and moisture from entering the housing 10 and ensuring the safety and cleanliness of the internal environment of the housing 10. In addition, this structural design simplifies the assembly operation, reduces the assembly difficulty and the probability of errors, and is conducive to mass production and maintenance. In summary, the structure of the limiting groove 102 and the stop 25 effectively solves the problems of inaccurate positioning, poor sealing and easy detachment of the traditional protective cover 20, and achieves the technical effects of accurate assembly positioning, strong sealing and stable structure of the protective cover 20.

[0030] Please see Figure 3 As shown, Figure 3 This is a side view of the protective cover 20 provided in this embodiment of the utility model.

[0031] This embodiment provides a structurally improved protective cover 20, which includes a main body, a skirt 22, and a fastener 23. The skirt 22 extends downward from the main body of the protective cover 20 and is used to fit against the outer wall of the housing 10 to enhance the sealing and protective effect. A notch 24 with a depth of H1 is provided at the lower part of the skirt 22. The fastener 23 is provided in the notch 24 and is connected to the skirt 22 to achieve a reliable fastening with the mating parts on the housing 10. The overall height of the skirt 22 is H2, and the depth H1 of the notch 24 and the height H2 of the skirt 22 satisfy the relationship 0.2H2≤H1≤0.5H2. Specifically, the fastener 23 is provided inside the notch 24, occupying the position of the notch 24 and forming an integral structure with the skirt 22, so that the fastener 23 has sufficient size and strength to achieve a firm connection between the protective cover 20 and the housing 10. Through the above structural design, during the actual assembly process, the skirt 22 of the protective cover 20 can provide a good fit and seal between the protective cover 20 and the box 10, while the buckle 23 at the notch 24 facilitates the quick and stable fastening of the protective cover 20 and the slots and other structures on the box 10, thereby improving the assembly efficiency and reliability of the protective cover 20.

[0032] This technical solution effectively solves the problems of inconvenience and weak fastening in the assembly process of traditional protective cover 20 structures by limiting the depth H1 of the notch 24 and the height H2 of the skirt 22 to 0.2H2≤H1≤0.5H2 and setting a fastening part 23 in the notch 24. Specifically, this size ratio ensures that the notch 24 has adequate space, allowing the fastening part 23 to be designed to be thick and stable enough, thus providing reliable connection force when the protective cover 20 is fastened to the box 10. At the same time, the height of the remaining part of the skirt 22 is guaranteed, avoiding the problem of reduced structural strength and weakened sealing performance of the skirt 22 due to the notch 24 being too deep. By setting the fastening part 23 in the notch 24, the fastening part 23 can make full use of the space of the notch 24 to achieve precise fastening with the box 10, preventing the protective cover 20 from loosening or falling off. In addition, the continuity and height of the skirt 22 further improve the covering and sealing effect of the protective cover 20 on the box 10, preventing external dust and moisture from entering the interior of the box 10. In summary, this technical solution, by rationally designing the ratio of the depth of the notch 24 to the height of the skirt 22, and cleverly integrating the buckle 23 into the notch 24, takes into account the ease of assembly, the firmness of connection, and the sealing performance, thereby achieving the overall optimization of the structure of the protective cover 20 and significantly improving the product's performance and reliability.

[0033] This embodiment discloses an improved protective cover 20 structure, including a main body, a skirt 22, and a fastener 23. The skirt 22 extends downward from the main body and is used to fit against the outer wall of the housing 10 to achieve sealing and protection. A notch 24 is provided at the lower part of the skirt 22, and the fastener 23 is disposed in the notch 24 for fastening with the mating structure on the housing 10. Specifically, the width between the fastener 23 and the side wall of the notch 24 is D1, and the width of the fastener 23 itself is D2, and these two satisfy the relationship 0.1D2≤D1≤0.3D2. That is, the gap between the side wall of the notch 24 and the fastener 23 is strictly limited to 10% to 30% of the width of the fastener 23. In actual assembly, the fastener 23 is firmly engaged inside the notch 24, and the side walls on both sides of the notch 24 maintain an appropriate distance from the fastener 23, which facilitates the assembly and positioning of the fastener 23 and ensures the overall stability and durability of the structure.

[0034] This technical solution effectively improves upon existing protective cover 20 assembly issues such as inaccurate positioning of the buckle 23, assembly wobbling, and structural damage by limiting the width D1 between the buckle 23 and the side wall of the notch 24 to 0.1 to 0.3 times the width D2 of the buckle 23. Specifically, if D1 is too small (below 0.1D2), the gap between the buckle 23 and the side wall of the notch 24 will be too narrow, potentially making it difficult to insert or remove the buckle 23 during assembly, reducing assembly efficiency and easily causing jamming and damage. If D1 is too large (above 0.3D2), the gap will be too wide, causing the buckle 23 to wobble after assembly, affecting the stability of the fastening and sealing performance, and even causing loosening or detachment during use. By adopting the gap range defined in this solution, it ensures that the buckle 23 has adequate operating space during assembly, facilitating quick and smooth installation, and also improves structural stability after assembly through the support of the side wall, preventing wobbling and loosening. Meanwhile, the reasonable gap can effectively buffer the impact of external forces on the buckle 23, extending the overall service life of the protective cover 20. In summary, this technical solution effectively solves the problems of inconvenient assembly, unstable positioning, and easy structural damage in the prior art by precisely defining the relationship between the buckle 23 and the side wall width of the notch 24, achieving the technical effects of convenient assembly, reliable fastening, good sealing and durability.

[0035] This embodiment provides a battery box structure with excellent sealing performance, including a box body 10, a protective cover 20, and waterproof adhesive. The protective cover 20 is fastened to the box body 10 via a fastener 23, resulting in a stable and reliable overall structure. Waterproof adhesive is provided at the joint area between the protective cover 20 and the box body 10. Specifically, the waterproof adhesive is placed between the inner edge of the protective cover 20 and the corresponding contact surface of the box body 10. During assembly, the waterproof adhesive can be applied continuously along the joint between the protective cover 20 and the box body 10 in the form of a ring-shaped sealing strip or a sealing gasket. When the protective cover 20 and the box body 10 are fastened together, the waterproof adhesive is moderately compressed, filling and sealing the gap between them, effectively preventing moisture, dust, or other external impurities from seeping into the interior of the box body 10. The waterproof adhesive can also be injected in liquid form and allowed to solidify.

[0036] This technical solution addresses the problem of existing battery box structures being prone to water and dust ingress in humid or rainy environments, leading to damage or failure of internal components, by adding waterproof adhesive between the protective cover 20 and the box body 10. The waterproof adhesive, acting as a sealing medium, is continuously distributed throughout the circumference of the joint between the protective cover 20 and the box body 10, effectively filling any gaps and minor unevenness, forming a robust sealing barrier. This effectively prevents moisture, humidity, and dust from seeping into the box body 10, even when the battery box is exposed to outdoor or harsh environments for extended periods, ensuring the safe and stable operation of the battery and related electronic components. Furthermore, the flexible nature of the waterproof adhesive buffers the assembly stress between the protective cover 20 and the box body 10, preventing seal failure due to mechanical vibration or thermal expansion and contraction, thus extending the battery box's lifespan. In summary, this technical solution, by incorporating waterproof adhesive, achieves efficient sealing of the battery box structure, reliably meeting the practical needs for waterproofing and dustproofing, and significantly improving the product's safety and durability.

[0037] This embodiment provides an improved battery box structure, including a box body 10, a protective cover 20, waterproof adhesive, and a stop plate 12. The box body 10 has an assembly port 101 for installation and removal, and the stop plate 12 is arranged around the assembly port 101. A groove is formed between the stop plate 12 and the wall of the box body 10, creating an adhesive groove 103 for receiving the waterproof adhesive. During assembly, the protective cover 20 is first fastened onto the assembly port 101, and then the waterproof adhesive is evenly placed in the adhesive groove 103. The waterproof adhesive is confined within the adhesive groove 103, filling the gap between the protective cover 20 and the box body 10, and achieving a sealing effect after solidification.

[0038] This technical solution addresses the technical problems of waterproof adhesive displacement, unstable sealing, leakage, and inconvenient assembly in existing assembly structures by setting a stop plate 12 around the assembly port 101 of the housing 10 to form a dedicated adhesive groove 103, and placing the waterproof adhesive within the adhesive groove 103. The stop plate 12 securely limits the waterproof adhesive during installation and use, preventing it from falling off or shifting due to pressure, vibration, or thermal expansion and contraction, thus ensuring the waterproof adhesive remains in an ideal sealing position. Furthermore, the adhesive groove 103 can accommodate and define the volume and shape of the waterproof adhesive, ensuring its even distribution around the assembly port 101, greatly improving the continuity and reliability of the seal. This structure effectively prevents external impurities such as moisture and dust from seeping into the housing 10 through the assembly port 101, fundamentally solving the problems of poor sealing and adhesive leakage in traditional structures, achieving convenient assembly, stable sealing, and simple maintenance. In summary, this technical solution, through the design of forming a glue groove 103 by the stop plate 12 and confining the waterproof glue in the glue groove 103, significantly improves the protection performance and durability of the battery box, and ensures the safety and long-term stable operation of the internal components of the box 10.
