Specific embodiments
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model. Embodiment
[0024] Please refer to Figures 1 to 6, the present utility model provides a technical solution: a battery pack with a card slot structure, which includes a main housing 1. A plug 3 is connected to the outside through the upper surface on one side of the main housing 1. A plurality of batteries 2 are fixedly connected inside the main housing 1. The electrode plates of the batteries 2 are fixedly connected to the lower end of the plug 3. A plug fixing plate 4 is fixedly connected to the upper surface of the main housing 1, and the plug 3 penetrates and is connected to the outside of the upper end of the plug fixing plate 4. The upper surface of the main housing 1 is symmetrically snap-connected with a first half convex shell 5 and a second half convex shell 6. A set of symmetric outer card frames 9 are connected inside both the first half convex shell 5 and the second half convex shell 6, and the plug fixing plate 4 is slidably inserted inside the outer card frames 9. A pressing plate 12 is slidably connected inside the obliquely upward upper surface on the other side of the main housing 1. A sliding plug plate 13 is fixedly connected to the side of the pressing plate 12 away from the plug 3. An inner sliding groove 14 for the sliding plug plate 13 to be inserted and slide is opened inside the main housing 1. An inner cylinder 11 is fixedly connected inside the main housing 1. A pressing frame 15 and a clamping plate 16 are fixedly connected to the side of the pressing plate 12 close to the plug 3. A sliding column 20 slidably arranged inside the inner cylinder 11 is fixedly connected to the lower surface of the pressing frame 15. A spring 21 for pressing is welded between the lower surface of the pressing frame 15 and the bottom wall of the inner cylinder 11. A clamping platform 17 is fixedly connected inside the main housing 1 and above the inner cylinder 11. A clamping hook platform 18 is fixedly connected to the front ends of the first half convex shell 5 and the second half convex shell 6. The clamping hook platform 18 is clamped and abuts against the upper surface of the clamping platform 17. A card slot 19 for the clamping plate 16 to be clamped is opened on one side of the first half convex shell 5 and the second half convex shell 6 where the clamping hook platform 18 is located.
[0025] More specifically, in this embodiment, first, by using the first half convex shell 5 and the second half convex shell 6 symmetrically clamped on the main housing 1, it effectively provides a peripheral wrapping protection effect for the plug 3 of the battery pack, so that the upper electric tool can be inserted into the notch formed by the first half convex shell 5 and the second half convex shell 6, ensuring the protection of the battery pack.
[0026] When the operator installs, first press the pressing plate 12. The pressing plate 12 drives the sliding plug plate 13 to slide in the inner sliding groove 14 by using the elastic restriction of the spring 21 and the sliding column 20 sliding in the inner cylinder 11. At the same time, it also drives the pressing frame 15, the clamping plate 16 and the sliding column 20 to slide downward. Then, slide and snap the outer card frames 9 of the first half convex shell 5 and the second half convex shell 6 onto the two sides outside the plug fixing plate 4 in sequence, and then loosen the pressing plate 12. When loosening, the spring 21 drives the pressing frame 15 and the clamping plate 16 to move upward, and the clamping plate 16 is snapped into the card slot 19 formed by the clamping platform 17 and the first half convex shell 5 and the second half convex shell 6. In this way, it not only ensures the convenient snap-in of the first half convex shell 5 and the second half convex shell 6, but also improves the stability of the first half convex shell 5 and the second half convex shell 6 installed on the main housing.
[0027] Furthermore, the outer surfaces of the first semi-convex shell 5 and the second semi-convex shell 6 are polished with concave-shaped sunken sliding platforms 8, and an outwardly convex ring plate 7 is fixedly connected to the upper outer surfaces of the first semi-convex shell 5 and the second semi-convex shell 6.
[0028] It should be noted that the sunken sliding platforms 8 of the first semi-convex shell 5 and the second semi-convex shell 6 are convenient for the operator to pinch when the fingers are sunken, and the sunken sliding platforms 8 will not scratch the operator's hand, having a protective effect. In addition, when disassembling and assembling the first semi-convex shell 5 and the second semi-convex shell 6, or when plugging in the upper-end power tool, the outwardly convex ring plate 7 can prevent the operator from having a hand-sliding phenomenon upwards due to the smoothness of the sunken sliding platforms 8.
[0029] Embodiment 2, on the basis of the above embodiment:
[0030] Further, special-shaped card slots 22 are provided on the connecting surfaces on both sides of the first semi-convex shell 5, special-shaped card strips 23 are clamped inside the special-shaped card slots 22, and the special-shaped card strips 23 are fixedly connected to the connecting surfaces on both sides of the second semi-convex shell 6. Convex rods 24 are fixedly connected to both sides of the upper surface of the plugging plate 4. Concave openings 25 for the convex rods 24 to abut against are provided inside the first semi-convex shell 5 and the second semi-convex shell 6. Reinforcing ribs 10 are fixedly connected inside the first semi-convex shell 5 and the second semi-convex shell 6. The card plate 16 is specifically designed in an anti-fooling shape of an inserted foot convex character, and four diagonal reinforcing ribs 161 are equidistantly connected between the card plates 16.
[0031] More specifically, in this embodiment, when the first semi-convex shell 5 and the second semi-convex shell 6 are slidably inserted, the special-shaped card strips 23 will slide into the special-shaped card slots 22, and the convex rods 24 will also abut against the concave openings 25 for limiting. In addition, the reinforcing ribs 10 ensure the reliable strength of the whole of the first semi-convex shell 5 and the second semi-convex shell 6.
[0032] The card plate 16 designed in an anti-fooling shape of an inserted foot convex character also ensures the stability of the insertion, and the diagonal reinforcing ribs 161 can strengthen the anti-disconnection buckle purpose.
[0033] Further, four insertion openings 41 for inserting the plug 3 are provided on the upper surface of the plugging plate 4. The insertion openings 41 are respectively the negative electrode, ID, C, and positive electrode from left to right. An anti-fooling groove 26 is provided on the surface of the main housing 1 close to the insertion openings 41.
[0034] Specifically, the operator can perform power-on insertion according to the corresponding positions of the four insertion openings 41 of the negative electrode, ID, C, and positive electrode. During the insertion process, the anti-fooling groove 26 can prevent the wrong insertion of different chargers.
[0035] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
