DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0022] like Figures 1 to 4As shown, the 12V small car-specific starting power supply described in this embodiment includes a shell 10 and a battery module 20. The battery module 20 includes a plurality of battery cells 21 overlapping each other, and each of the battery cells 21 is a flat structure; the shell 10 is enclosed by side panels 11 that are attached to the six sides of the battery module 20, and both ends of the shell 10 in the length direction are provided with a base 30, and the sides of the two bases 30 facing away from each other are provided with fixing feet 40; the tops of the two bases 30 are provided with at least two riveted studs 50 along the width direction of the shell 10, and each of the riveted studs 50 is detachably connected to a main control board 60 connected to the battery module 20 by screws, and the main control board 60 is separated from the shell 10 to form a heat dissipation gap 70, and the main control board 60 is electrically connected to a positive electrode post 61, a negative electrode post 62 and a charging port 63.

[0023] In practice, the housing 10 is made of ABS plastic, which offers excellent insulation and impact resistance. It consists of six independent side panels 11 connected by a snap-fit ​​structure (e.g., a mortise and tenon joint) for ease of assembly and maintenance. The battery module 20 is comprised of a plurality of flat battery cells 21, which are positioned horizontally within the housing 10 to maximize space utilization and increase energy density. In this embodiment, a first insulating plate 22 is provided between each of the battery cells 21 to enhance the safety of the battery pack.

[0024] Two bases 30 are mounted on either end of the housing 10 along its length. Mounting feet 40 are provided on the bases 30 for securing the starting power supply to various containers or devices, such as sheet metal boxes and plastic boxes, enabling a high degree of flexibility and customization. The combination of the bases 30 and mounting feet 40 securely fastens the housing 10 and battery module 20, eliminating the need for additional fasteners on the side panels 11. This simplifies the structure and improves reliability.

[0025] The main control board 60 is mounted on top of the base 30 and connected to the base 30 via self-clinching studs 50. This design facilitates installation and removal of the main control board 60 and enhances the stability of the connection. A heat dissipation gap 70 is provided between the main control board 60 and the housing 10 to ensure effective heat dissipation during operation, thereby improving its reliability and service life. In this embodiment, the main control board 60 integrates a positive electrode post 61, a negative electrode post 62, and a charging port 63, facilitating connection to a car battery and charger.

[0026] This design securely encloses the battery module 20 within the housing 10, while the side panels 11 effectively protect the battery module 20 from external environmental influences. Furthermore, through the base 30 and mounting feet 40, users can flexibly integrate the starting power supply into various toolboxes to meet the personalized needs of different users. This solution balances performance with product safety, reliability, flexibility, and ease of use.

[0027] In some embodiments, as Figure 1 As shown, the fixing foot 40 is provided with at least two screw holes. These screw holes allow for fastening with bolts or screws, providing more flexible installation options. Users can choose different sizes and types of bolts / screws, as well as different installation methods, such as direct attachment to a flat surface, using a bracket, or using other fasteners. Furthermore, compared to other fastening methods such as snap-fit ​​or adhesive attachment, bolts / screws provide a stronger hold, making the starting power supply more stable and less likely to loosen or fall off. This effectively prevents displacement or damage to the starting power supply, especially in vibrating environments such as those experienced by a moving vehicle.

[0028] In some embodiments, the fixing legs 40 are integrally formed with the base 30. This integrally formed structure is generally more durable than an assembled structure because it eliminates weak links at the joints. This effectively prevents breakage or deformation of the fixing legs 40, which must withstand certain stresses. Furthermore, this integrally formed structure eliminates additional assembly steps such as welding, bonding, or screwing, thereby simplifying the production process, improving production efficiency, and reducing manufacturing costs.

[0029] In some embodiments, the side panels 11, the base 30 and the fixing legs 40 are all made of insulating flame-retardant materials. In this embodiment, the insulating material can prevent the occurrence of leakage and electric shock accidents, while the use of flame-retardant materials can minimize the risk of fire.

[0030] In some embodiments, as Figure 1 As shown, the side of the base 30 is further provided with a plurality of notches 31. On the one hand, the design of the notches 31 enhances heat dissipation to enhance the reliability and service life of the product, and on the other hand, it can also reduce the overall weight of the product while ensuring strength.

[0031] In some embodiments, as Figure 2 、 Figure 4As shown, the side panels 11 include a top panel 111 and a bottom panel 112, as well as four sub-panels 113 supported between the top and bottom panels. Since the battery cells 21 are flat and relatively weak in their resistance to deformation in the thickness direction, the support design of multiple sub-panels 113 effectively enhances the strength of the side panels 11 in the thickness direction of the battery cells 21, enabling them to better resist deformation and bending caused by external impact or pressure, thereby protecting the integrity and safety of the battery module 20.

[0032] In some embodiments, as Figure 2 、 Figure 4 As shown, second insulating plates 114 are disposed on the opposing surfaces of the top plate 111 and the bottom plate 112. Positioning grooves 115 are formed on the circumferential edges of the second insulating plates 114, spaced from the circumferential edges of the top and bottom plates 111, 112. The second insulating plates 114 further enhance insulation performance and provide dual protection. Furthermore, the second insulating plates 114 are secured to the opposing surfaces of the top and bottom plates 111, 112, and the positioning grooves 115 formed therein provide clear assembly guides when assembling the four sub-plates 113, enabling them to be quickly and accurately installed between the top and bottom plates, thereby improving assembly precision and efficiency and reducing assembly errors.

[0033] In some embodiments, the overlapped length of the base 30 and the housing 10 is 1 / 4 of the length of the housing 10. In this embodiment, the base 30 is primarily used to support and secure the housing 10. Two bases 30 are symmetrically located at both ends of the housing 10, collectively providing support equivalent to half the length of the housing 10. This ensures the stability of the starting power supply during placement or installation, effectively distributing the weight of the battery module 20, and preventing deformation of the bottom plate 112.

[0034] In some embodiments, as Figure 1 、 Figure 2 As shown, four self-clinching studs 50 are provided, and the four self-clinching studs 50 are respectively located at the four corners of the top end of the housing 10. The four-corner arrangement can more evenly distribute the stress on the main control board 60 on the housing 10, avoiding stress concentration, thereby improving the stability of the overall structure, especially when subjected to external impact or vibration, and can better protect the main control board 60 and the electronic components thereon.

[0035] The 12V small car-specific starting power supply provided in this embodiment achieves a high degree of flexibility and customization through modular design and simple fixing methods. Users can easily integrate the battery module into various types of containers or equipment, such as sheet metal boxes, according to their own needs, thereby obtaining a more convenient and personalized user experience, expanding the product's application scenarios, and enhancing market competitiveness.
