Preferred embodiments of the present invention are described below with reference to the accompanying drawings:

as shown in fig. 1 and fig. 2, in the present embodiment, the fastening structure for fixing the battery includes two cover plates 20, namely a first cover plate 21 and a second cover plate 22, which are oppositely disposed, and a plurality of brackets 40 detachably connected to the first cover plate 21 and the second cover plate 22, respectively, the first cover plate 21 and the second cover plate 22 are detachably connected to the brackets 40 through the fastening structure, and an accommodating cavity 100 for fixing the battery is formed after the assembly. Clamping elbow 30 among the buckle structure sets up on the opposite face of first apron 21 and second apron 22, and preferably, first apron 21 and second apron 22 are rectangle, and clamping elbow 30 is square block, and a plurality of clamping elbows 30 set up on the edge all around of two rectangle apron 20 opposite faces, and optionally, in this embodiment, be provided with 4 clamping elbows 30 on four angles of first apron 21 and second apron 22 opposite faces respectively. Of course, the first cover plate 21 and the second cover plate 22 may be designed in other shapes, and the snap bend 30 may be designed in other shapes according to the actual assembly requirements of batteries with different shapes, which is not limited herein.

As shown in fig. 1 to fig. 3, the end of the clamping elbow 30 is provided with a convex rib 31, a clamping groove 41 in the clamping structure is disposed on the bracket 40, preferably, the clamping groove 41 is hollowed out at the end of the bracket 40, the clamping groove 41 is square and adapted to the clamping elbow 30, and the first cover plate 21 and the second cover plate 22 are connected to the bracket 40 by the clamping elbow 30 and the clamping groove 41. Preferably, a plurality of supports 40 all are rectangular shaped plate, and a plurality of rectangular shaped support 40 passes through the buckle with two rectangle apron and is connected the combination, and optionally, in this embodiment, 4 rectangle support's tip respectively with first apron 21 and second apron 22 four on four angles 4 joint elbow 30 buckle connection, form the chamber 100 that holds that is the cuboid. Of course, the bracket 40 may be designed to be other shapes with the first cover plate 21 and the second cover plate 22, and the snap groove 41 may be designed to be other shapes with the snap elbow 30 according to the actual assembly requirements of batteries with different shapes, which is not limited herein. The buckle structure of the fixed battery in the embodiment can effectively prevent the clamping elbow 30 from loosening and deviating from the clamping groove 41 by arranging the convex ribs 31 at the end part of the clamping elbow 30, and the service life of the battery pack is prolonged.

As shown in fig. 1 to fig. 3, in the present embodiment, an assembling groove 42 intersecting with the clamping groove 41 is hollowed at the end of the bracket 40, preferably, the assembling groove 42 is in a long strip shape, and a slotted hole of the long strip-shaped assembling groove 42 is designed to be U-shaped. When the battery is assembled through external force, the assembling groove 42 expands under the action of the external force to drive the clamping groove 41 to expand and enlarge, so that the clamping structure can be clamped easily and quickly, after the external force is removed, the assembling groove 42 automatically contracts and returns to the original position, and the clamping structure is clamped with the clamping groove 41 through the clamping elbow 30 and the convex edge 31 at the end part of the clamping elbow 30 to realize firm connection; when dismantling, changing the battery through external force, assembly groove 42 receives the exogenic action with the inflation grow, drives joint groove 41 inflation grow to make joint elbow 30 can easily, deviate from joint groove 41 fast, after unloading external force, assembly groove 42 and joint groove 41 automatic contraction return the normal position size. The buckle structure of the fixed battery in the embodiment can realize the detachable connection of the buckle by arranging the assembling groove 42 crossed with the buckle groove 41, so that the battery pack is convenient to detach and replace, and the buckle structure can be used repeatedly and is not easy to damage.

In the present embodiment, as shown in fig. 2 and 4, the inside of the snap groove 41 is provided with a step 43 adapted to the rib 31 at the end of the snap elbow 30.

When dismantling the battery through external force, when changing, assembly groove 42 receives the exogenic action and will expand the grow, drive joint groove 41 inflation grow, the bead 31 of joint elbow 30 tip this moment unclamps each other with the inside step 43 in joint groove 41 and detains, the bead 31 of joint elbow 30 tip after loosening each other and detaining crosses step 43, loosen and take off in joint groove 41, external force is lacked, assembly groove 42 and the automatic shrink of joint groove 41, the normal position size of returning, the dismantlement of buckle structure has been realized.

Of course, the snap-fit elbow 30 and the snap-fit groove 41 may be snap-fit connected by other methods, for example, the step 43 may not be disposed inside the snap-fit groove 41, the rib 31 at the end of the snap-fit elbow 30 may directly pass through the snap-fit groove 41 to buckle the notch at the other end of the snap-fit groove 41, and the step 43 disposed inside the snap-fit groove 41 is taken as an example for description, and is not limited only.

In the embodiment, as shown in fig. 3, preferably, the end of the snap-in elbow 30 is provided with a rib 31 all around, optionally, the rib 31 may be continuously provided around the end of the snap-in elbow 30, or the ribs 31 may be provided at intervals, which is not limited herein; as shown in fig. 4, correspondingly, steps 43 adapted to the ribs 31 are disposed around the inside of the locking groove 41, and the dimensions of the ribs 31 and the steps 43 can be designed according to actual requirements.

As shown in fig. 1 and 2, the assembling groove 42 is preferably vertically crossed with the clamping groove 41, and the width of the assembling groove 42 is smaller than that of the clamping groove 41. The assembling groove 42 and the clamping groove 41 are both hollowed-out, the clamping groove 41 is mainly connected with the clamping elbow 30 in a clamping mode, and the slender assembling groove 42 can be matched with a clamping structure through expansion and contraction deformation characteristics to complete installation and disassembly. Alternatively, the assembling groove 42 and the fastening groove 41 may form a cross, and the length of the groove gap at the end of the assembling groove 42 close to the cover plate 20 after the cross is slightly shorter, and the length of the groove gap at the end of the assembling groove 42 far from the cover plate 20 is slightly longer, so as to ensure that the fastening groove 41 and the assembling groove 42 can be kept intact without damage under the condition of repeatedly replacing the battery. Of course, the assembling groove 42 and the clamping groove 41 can be crossed at other angles less than 180 °, which is not limited herein.

In the present embodiment, as shown in fig. 2 and 3, it is preferable that the rib 31 at the end of the snap elbow 30 is provided with a first chamfer 32 for facilitating the snap connection between the snap elbow 30 and the snap groove 41. When the battery is fixed, the clamping elbow 30 slides into the clamping groove 41 along the angle of the first chamfer 32 on the end convex edge 31 under the action of external force, so that the quick assembly of the clamping structure is realized. Preferably, a second chamfer 44 is provided at the edge of the notch where the snap groove 41 initially contacts the snap elbow 30 to facilitate the snap engagement of the snap elbow 30 with the snap groove 41. The second chamfer 44 at the notch cooperates with the first chamfer 32 on the rib 31 at the end of the snap elbow 30 to further facilitate the quick assembly of the snap structure.

As shown in fig. 2, in the present embodiment, the end of the clamping elbow 30 is disposed toward the outside of the accommodating cavity 100, so that the internal space of the accommodating cavity 100 can be increased, and the space utilization rate is improved.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
