[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] In the present utility model, the descriptions involving "first", "second", "upper", "lower", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", "upper", "lower" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the technical solutions between the embodiments can be combined, they are all within the protection scope required by the present utility model.

[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0032] like Figures 1 to 3 As shown, a quick-install rack for batteries of energy storage equipment includes: a cell 100 and a battery base. A plurality of cells 100 are connected in the horizontal and vertical directions to form the rack, and each of the cells 100 includes a carrier plate 110 and a top plate connected by four columns 120, and the cell 100 has a relative insertion port and an electrical connection port. The two columns 120 near the electrical connection port are connected by a crimping mechanism 200, and the crimping mechanism 200 includes a rotating shaft 220, and the rotating shaft 220 is rotatably connected to the column 120. A baffle 230 opposite to the battery is provided on the rotating shaft 220, and the middle part of the baffle 230 is connected to the rotating shaft 220, and the two ends of the baffle 230 extend toward the carrier plate 110 and the top plate to form an abutment portion 231 and a crimping portion 232, respectively. The battery body is fixed on the battery base, and protrudes from the battery body at one end of the battery base close to the electrical connection port. The protruding portion corresponds to the abutment portion 231 of the baffle 230. The battery body is inserted from the insertion port and pushed toward the electrical connection port. The abutment portion 231 is pushed by the protruding portion, driving the rotating shaft 220 to rotate until the crimping portion 232 is crimped onto the upper surface of the battery base.

[0033] After the battery module is inserted from the insertion port, it is pushed into the electrical connection port. When the battery base near the electrical connection port touches the abutment portion 231, it continues to be pushed, the rotation shaft 220 rotates, and the baffle 230 rotates accordingly until the crimping portion 232 presses on the upper surface of the battery base. The battery base is clamped by the crimping portion 232 and the carrier plate 110, thereby realizing the rapid fixation of the battery module. The above structure of this embodiment is simple, does not require a lot of manpower operation, shortens the installation time, and improves the installation efficiency.

[0034] Furthermore, the abutting portion 231 is in a plate shape, and the pressing portion 232 is in an arc shape protruding away from the rotating shaft 220 .

[0035] The crimping portion 232 is formed in an arc shape, which facilitates the crimping portion 232 to rotate on the surface of the battery base until the battery base is pressed tightly, while preventing the baffle 230 from scratching the battery base.

[0036] Furthermore, the rotating shaft 220 is connected to the column 120 via a torsion spring, and in a state without being subjected to force, the abutting portion 231 extends toward the direction of the supporting plate 110 .

[0037] After the rotating shaft 220 is pushed and rotated to a certain angle by the battery base, when the battery is removed, the baffle 230 cannot return to its original state, which is not conducive to the installation of the battery next time. After the torsion spring is set, before the battery is installed, the abutment portion 231 of the baffle 230 is vertically downward, and the battery seat pushes the abutment portion 231, driving the rotating shaft 220 to rotate, the torsion spring is deformed, and a restoring force is generated. When the battery is removed, the rotating shaft 220 rotates in the opposite direction under the action of the restoring force, the torsion spring returns to a free state, and the abutment portion 231 returns to a vertical downward position.

[0038] It should be noted that, in order to facilitate the rotation of the rotating shaft 220 and to play a locking role, preferably, the hole on the column 120 that matches the rotating shaft 220 is a square hole 210, and the four corner fillet radii are determined according to the actual design and cannot be too large, as long as the stress can be eliminated and scratches on the rotating shaft 220 and the operator can be avoided. For example, the fillet radius r can be designed to be less than 1mm, preferably, r<0.5mm. Correspondingly, the part of the rotating shaft 220 that matches the square hole 210 is basically square, and the four corners are filleted, and the fillet radius R>r, which is convenient for the rotation of the rotating shaft 220, and the four side lengths are guaranteed to be able to lock the rotating shaft 220 with the four side lengths of the square hole 210.

[0039] Furthermore, at least one pin hole is respectively provided on the two side walls of the battery body near the electrical connection port. A first pin 300 corresponding to the pin hole is respectively provided on the column 120 near the electrical connection port, and the first pin 300 is retractable.

[0040] Preferably, two first pins 300 are disposed in the up-down direction on each column 120 . A spring is disposed inside the column 120 to abut against the first pins 300 .

[0041] Furthermore, at least one second pin 400 is provided on the carrying plate 110 near the insertion port, and the second pin 400 is retractable.

[0042] Preferably, at least two second pins 400 are arranged side by side on one side of the insertion port. Similarly, a spring is arranged inside the bearing plate 110 to abut against the second pins 400 .

[0043] Furthermore, the portion of the first pin 300 protruding from the surface of the column 120 is in a hemispherical shape. The portion of the second pin 400 protruding from the surface of the supporting plate 110 is in a hemispherical shape.

[0044] The first pin 300 and the second pin 400 are both cylindrical, and the ends are hemispherical. In a free state, the length l of the cylindrical portion of the first pin 300 outside the column 120 needs to be less than half the thickness of the battery housing wall plate, so that the battery housing wall plate can press the first pin 300 into the interior of the column 120. The cylindrical portions of the first pin 300 and the second pin 400 are provided with steps inside the column 120 to prevent the column 120 from being ejected under the restoring force of the spring.

[0045] Furthermore, at least one guide member 500 extending from the insertion port to the electrical connection port is provided on the carrier plate 110. At least one slide groove cooperating with the guide member 500 is provided at the bottom of the battery base.

[0046] When the battery module is inserted, the cooperation between the guide member 500 and the slide groove ensures that the battery module does not deflect.

[0047] Furthermore, the battery base is the bottom plate of the battery body.

[0048] The battery base can be the bottom plate of the battery housing, the bottom plate is in an N shape, two side walls are arranged at both ends of the insertion direction, and opposite openings are arranged on the side walls to form a slide groove. Preferably, in order to prevent the bottom plate from scratching the carrier plate 110 and reduce friction, a roller is arranged at the bottom of the bottom plate.

[0049] Furthermore, the battery base is connected to the battery body by bolts.

[0050] The battery base can be arranged in a separate form from the battery body, and the structure is the same as the above-mentioned battery base.

[0051] Furthermore, each of the units 100 is connected by plugging.

[0052] Each unit cell 100 of the rack can be formed by connecting a plurality of columns 120 and a plurality of beams to each other. In order to improve the assembly efficiency, the rack is preferably modular, and each unit cell 100 is formed by connecting a column 120 at each of the four corners of the bearing plate 110. The top plate is the bearing plate 110 of the upper unit cell 100, and the top plate of the uppermost layer is separately provided with a top plate buckled on each column 120. Each column 120 is respectively inserted into the four corners of the upper bearing plate 110. Laterally, protrusions are provided at both ends of one side of the bearing plate 110, and pits cooperating with the protrusions are provided at both ends of the other side, and adjacent units 100 are laterally connected by inserting the protrusions into the pits. In order to increase stability, each plug-in combination is fixed by screws, or elastic pins and pin holes are provided.

[0053] Although the utility model is disclosed as above, the utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the scope defined by the claims.
