[0030] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0031] As shown in the figure, a kidney-shaped steel ring 1 that is convenient for fixing includes: a connecting ring 10 and an inner ring 11 disposed inside the connecting ring 10;

[0032] The connecting ring 10 is integrally rectangularly arranged, and an installation hole is provided in the middle position of the connecting ring 10, and the shape of the installation hole is the same as the outer side of the inner ring 11;

[0033] The inner ring 11 is integrally kidney-shaped, and a kidney-shaped fixing hole 12 is provided in the middle part of the inner ring 11.

[0034] In a preferred embodiment of the present utility model, the inner ring 11 is made of a metal material, and the connecting ring 10 and the inner ring 11 are in interference fit.

[0035] It should be noted that the steel ring 1 is integrally rectangularly arranged, that is, the connecting ring 10. The kidney shape specifically refers to that the installation hole provided on the connecting ring 10 is kidney-shaped. Specifically, the middle part of the installation hole is rectangularly arranged, and the right-angled sides on the opposite sides of the rectangle are changed to semi-circular arc sides. That is, the kidney shape is specifically composed of a rectangle and two semi-circles. The two semi-circles are arranged on the opposite two sides of the rectangle to form a kidney-shaped structure. The above-mentioned installation hole, inner ring 11, and fixing hole 12 are all arranged in a kidney-shaped structure. The inner ring 11 and the installation hole inside the connecting ring 10 are connected by an interference fit method. One side of the outside of the connecting ring 10 is fixedly connected to the battery box, and a plurality of connecting rings 10 are provided on the battery box. When using bolts to fix the battery box, there is no need for precise calibration, so that the reserved position for placing the battery must be completely aligned with the fixing hole 12 before it can be fixed by bolts. Just directly place the battery box at the reserved position for placing the battery and then fix it with bolts. Finally, use fillers to fill and fix the outside of the battery box.

[0036] A battery box includes the kidney-shaped steel ring 1, and the battery box further includes a box body 2 and a fixing frame 3 fixed to the bottom of the box body 2. The steel ring 1 is disposed on the fixing frame 3;

[0037] It should be noted that the box body 2 is integrally arranged in a groove shape without a top seal, and is provided with a split cover plate. The cover plate can be snap-connected to the top of the box body 2. The battery is placed inside the box body 2. After the entire battery box is installed, the cover plate is snap-connected to the top of the box body 2, thereby fixing the battery inside the battery box. The fixing frame 3 is arranged at the bottom of the box body 2 for fixing the box body 2, and thus fixing the entire battery box. The fixing of the battery box is realized through the steel ring 1. The steel ring 1 is fixedly connected to the fixing frame 3. By using bolts to fixedly connect the steel ring 1 to an electric vehicle, a motor vehicle or the outdoor ground, the fixing of the battery box is realized. And when fixing, there is no need for precise calibration of the bolt holes. As long as the reserved circular bolt holes are aligned with any position inside the fixing holes 12 on the steel ring 1, the fixing can be carried out, avoiding repeated observation to note whether other bolt holes are aligned. At the same time, the inner ring 11 inside is made of technical materials, providing the required strength for the fixed connection of the bolts.

[0038] The box body 2 includes a plurality of rotating plates 21 and a plurality of straight plates 20. The rotating plates 21 can be folded. The box body 2 is integrally arranged without a top seal. The rotating plates 21 are placed in a U shape, and the rotating plates 21 are only rotatably connected to the straight plates 20.

[0039] In a preferred embodiment of the present invention, three rotating plates 21 are provided, which are respectively arranged at the bottom and both sides of the U shape, and the rotating plates 21 are not connected to each other.

[0040] In a preferred embodiment of the present invention, two straight plates 20 are provided, which are respectively arranged on the front and back sides of the U shape, and the straight plates 20 are rotatably connected to the rotating plates 21.

[0041] The box body 2 is generally a U-shaped box body 20, and the three rotating plates 21 are not connected to each other. Each rotating plate 21 can be folded symmetrically, and the axes of folding of the three rotating plates 21 are located in the same horizontal plane. The two straight plates 20 are respectively arranged on the front and rear sides of the box body 2, and the three rotating plates 21 are rotatably connected to the straight plates 20. The rotational connection between the rotating plates 21 and the straight plates 20 is realized by a hinge. The two sides of the hinge are fixedly connected to the rotating plates 21 and the straight plates 20 respectively. There is a gap between the rotating plates 21 and the straight plates 20, and the spacing of the gap is greater than or equal to the sum of the thicknesses of the rotating plates 21 and the straight plates 20, so as to avoid squeezing between the straight plates 20 and the rotating plates 21 during folding to the other side of the hinge direction. The folding means that the two hinges of the hinge can rotate 360° during the rotation process. Before the box body 2 needs to be stored, the angle of the hinge is 90° or 270°. When storing, storing at an angle gradually decreasing from the 90° direction is called storing toward the inside of the hinge, and vice versa. The spacing of the gap is greater than or equal to the sum of the thicknesses of the rotating plate 21 and the straight plate 20, so that the rotating plate 21 and the straight plate 20 can also be folded during the storage process toward the outside. At the same time, the rotating plate 21 itself can also be folded, so that when the box body 2 is not needed, it is only necessary to fold the box body 2 along the folding axis of the three rotating plates 21, the rotating plate 21 at the bottom is folded toward the inside of the box body 2, and the rotating plates 21 on both sides are folded toward the outside of the box body 2. During the folding process, the rotating plate 21 and the straight plate 20 rotate along the hinge and fold as well, so that the entire box body 2 is folded and gathered into a flat shape, which is convenient for storage, avoids occupying unnecessary space, and improves space utilization.

[0042] The fixing frame 3 includes two fixing rods 30 and a connecting rod 31 slidably connected to the fixing rods 30 ; the fixing rods 30 are fixedly connected to the bottom of the box body 2 ; the two fixing rods 30 are arranged opposite to each other, and the connecting rod 31 is used to connect the two fixing rods 30 .

[0043] In a preferred embodiment of the present invention, a sliding groove 37 is formed on one side opposite to the two fixing rods 30 , and the connecting rod 31 is slidably connected in the sliding groove 37 .

[0044] In a preferred embodiment of the present invention, a plurality of insertion holes 38 are evenly arranged in the slide groove 37, and fixing pieces are arranged at both ends of the connecting rod 31. The fixing pieces can be inserted into the insertion holes 38 to connect the fixing rod 30 and the connecting rod 31 into a whole.

[0045] It should be noted that the two fixing rods 30 are respectively fixedly connected to the bottoms of the two straight plates 20. The two straight plates 20 are arranged oppositely, so that the fixing rods 30 are also arranged oppositely. At this time, the adjacent sides of the two fixing rods 30 are the sides where the inner sides are located, and the side opposite to this side is the side of the outer side. The chute 37 is opened on the inner side surface of the fixing rod 30. At this time, a number of jacks 38 are opened on the two opposite side surfaces inside the chute 37, and the jacks 38 on the two opposite side surfaces are symmetrically arranged. Two side-by-side chutes 37 are opened on each fixing rod 30, and are divided into an upper row chute 37 and a lower row chute 37. The same jacks 38 are opened on each chute 37, and both ends of a number of connecting rods 31 are slidably connected to the chutes 37 of the two fixing rods 30. The same number of connecting rods 31 are arranged in the two rows of chutes 37. The connecting rods 31 play a role in connecting and fixing the entire fixing frame 3 and enhancing the integrity. Among them, two connecting rods 31 are a group, and a total of three groups are arranged. One group of connecting rods 31 is composed of a connecting rod 31 located in the upper row chute 37 and a connecting rod 31 located in the lower row chute 37, and the two connecting rods 31 in a group are arranged in a cross shape, so as to form a number of triangles, so as to connect the originally independent two fixing rods 30 together, thereby enhancing the overall structural strength and stability of the entire battery box, and at the same time improving the anti-twisting performance and the ability to resist external force impact, and playing a certain protective role for the battery.

[0046] In a preferred embodiment of the present invention, the fixing member includes: a rotating member 32, a moving rod 33 threadedly connected to the rotating member 32, and a top ball 34; through holes are respectively opened at both ends of the connecting rod 31, and the rotating member 32 is rotatably connected to the through holes; a moving groove is opened at the through holes, the moving rod 33 is slidably connected to the moving groove, a top groove is further opened at the top of the moving groove, the top ball 34 is arranged in the top groove, and clamping grooves are opened on both sides of the top groove.

[0047] In a preferred embodiment of the present invention, the centers of the moving groove, the moving rod 33, the top ball 34 and the rotating member 32 are located on the same axis, and the moving direction of the top ball 34 in the top groove and the moving direction of the moving rod 33 are located on the same axis.

[0048] In a preferred embodiment of the present invention, the clamping groove communicates the top groove with the outside of the connecting rod 31, a top shaft 36 is slidably connected in the clamping groove, and a spring 35 is sleeved on the circumference of the top shaft 36.

[0049] It should be noted that the fixation between the connecting rod 31 and the fixed rod 30 is specifically achieved through a fixing member. The fixing member is arranged inside both ends of the connecting rod 31. A through hole is opened at each position near both ends of the connecting rod 31. A rotating member 32 is rotatably connected at the through hole. At the same time, a moving groove is opened inside the connecting rod 31 near both ends. The moving groove is integrally cylindrical. The half part thereof near the rotating member 32 is provided with threads and is threadedly connected to the rotating member 32, so that rotating the rotating member 32 can control the forward and backward movement of the rotating member 32 in the moving groove. A top groove is opened at one end of the moving groove near the jack 38. The top ball 34 is arranged in the top groove. The moving groove and the top groove are communicated. The top ball 34 can move forward and backward in the top groove. In this way, during the forward and backward movement of the moving rod 33, the top ball 34 can be pushed to move. A clamping groove is also opened on the connecting rod 31. The clamping groove can be aligned with the jack 38. A top shaft 36 is slidably connected in the clamping groove. A spring 35 is sleeved on the circumference of the top shaft 36. Both ends of the spring 35 are fixedly connected to the clamping groove and the top shaft 36 respectively. When the spring 35 is in the initial state, the top shaft 36 is located inside the connecting rod 31, and the length of the top shaft 36 extends into the top groove. When the top ball 34 is pushed forward, the top ball 34 moves towards the jack 38 in the top groove. The top ball 34 gradually contacts the top shaft 36 and pushes the top shaft 36 out, so that the top shaft 36 is inserted into the jack 38. As the top shafts 36 at both ends of the connecting rod 31 are inserted into the jack 38, the fixation between the connecting rod 31 and the fixed rod 30 is completed. When storing, rotate the rotating member 32 again, and the moving rod 33 moves in the reverse direction. The thrust of the moving rod 33 on the top ball 34 disappears. The restoring deformation of the spring 35 drives the force exerted on the top ball 34 by the top shaft 36, thereby pushing the top ball 34 back to its original position. In this way, as the box body 2 is folded up, the angle of the cross-placed connecting rod 31 becomes larger, thus completing the same storage.
