Description

Technical Field

[0001] The utility model relates to the technical field of power exchange cabinets, and in particular to a waterproof battery compartment. Background Art

[0002] At present, battery swap cabinets, as an efficient energy supply solution for electric vehicles, are gradually becoming an important part of urban green travel infrastructure. This technology mainly provides electric vehicles with fast and convenient energy replenishment services through centralized storage and automatic battery replacement. The battery swap cabinet system usually includes key components such as intelligent management system, battery storage space (i.e. battery swap warehouse), battery handling robot arm, and necessary electrical connections and safety protection devices.

[0003] The battery body is set inside the battery swap compartment. If water enters, the battery body is easily damaged. In order to facilitate the placement of the battery body, the battery swap compartment is divided into two parts: the compartment body and the compartment cover. However, due to processing accuracy issues, gaps are prone to occur, resulting in inadequate sealing, which in turn causes water vapor to enter and corrode or cause a short circuit in the battery body.

DETAILED DESCRIPTION

[0024] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1

[0026] like Figure 1 The waterproof battery compartment shown includes a compartment body 100 and a compartment cover 200 , wherein an opening 101 is provided at one end of the compartment body 100 for installing the battery body placed inside, and the compartment cover 200 is sealed and fixed at the opening 101 of the compartment body 100 for sealing the compartment body 100 .

[0027] like Figure 2 As shown, the bin body 100 is provided with an outward step 110 near the opening 101, and the top of the outward step 110 is provided with an inclined edge 111. The outer edge of the bin cover 200 is provided with a convex edge 210, and the side of the convex edge 210 close to the bin cover 200 is set as an inclined surface 211, and the inclined surface 211 is tightly attached to the inclined edge 111. A sealing strip 201 is provided between the inclined surface 211 and the inclined edge 111 to play a sealing role. A fixing structure 300 is provided on the side of the convex edge 210 away from the bin cover 200 to fix it to the bin body 100 and provide a pressing force for the sealing strip 201.

[0028] like Figure 2 As shown, the fixing structure 300 is arranged at the convex step 110, and the convex step 110 is used to accommodate the fixing structure 300. A U-shaped structure 120 is provided on the top of the inclined edge 111, and the side of the U-shaped structure 120 is flush with the inner surface of the warehouse body 100; the U-shaped structure 120 cooperates with the convex step 110 to accommodate the fixing structure 300, which is convenient for the battery body to be installed.

[0029] like Figure 2 As shown, an oblong hole 212 is provided on the convex edge 210 , a round hole 102 is provided on the bin body 100 , and the fixing structure 300 is a bolt structure; the bolt structure passes through the oblong hole 212 and the round hole 102 to fix the bin cover 200 on the bin body 100 .

[0030] like Figure 2 As shown, the cross section of the sealing strip 201 is circular, and the circular sealing strip 201 can better withstand the pressing force from the inclined surface 211 and the inclined edge 111 .

[0031] like Figure 3 As shown, the warehouse body 100 includes a bottom plate 130 and side plates 140 fixed on the four sides of the bottom plate 130. One side of the side plate 140 is an integrally formed convex step 110, an inclined edge 111 and a U-shaped structure 120. The bottom plate 130 and the side plates 140 are welded and fixed to each other, and the side plates 140 are welded and fixed to each other in turn. Such a design ensures as few welding points as possible to avoid water ingress due to leakage points in welding. The bottom plate 130 and the side plates 140 are welded and fixed to each other mainly because the side plates 140 are relatively long and the cost of direct integral molding is too high.

[0032] like Figure 4 As shown, the bin cover 200 includes an integrally formed top plate 220 and side plates 230 arranged on the four sides of the top plate 220. One side of the side plate 230 is an integrally formed convex edge 210. The top plate 220 and all the side plates 230 are integrally formed, and the side plates 230 are welded and fixed in sequence. This design is also to ensure as few welding points as possible to avoid water ingress due to leakage points in welding.

[0033] Example 2

[0034] like Figure 5 As shown, the difference between this embodiment and embodiment 1 is that the fixing structure 300 includes a trapezoidal block 310, a bolt 320, a washer 330 and a nut 340, wherein the washer 330 is arranged between the flange 210 and the bin body 100, and the bin body 100, the flange 210, and the washer 330 are provided with the same rectangular hole 331, the trapezoidal block 310 is inverted and inserted into the rectangular hole 331, and a hypotenuse of the inverted trapezoidal structure is located on the side away from the bin cover 200, the nut 340 is fixed on the inner side of the rectangular hole 331 corresponding to the outer convex step 110, and the bolt 320 penetrates the trapezoidal block 310, the bin body 100, the flange 210 and the washer 330 from the bottom edge of the trapezoidal block 310 and is fixed on the nut 340.

[0035] When in use, it is only necessary to rotate the bolt 320 to drive the trapezoidal block 310 to move downward, so that the inclined edge of the trapezoidal block 310 presses the rectangular hole 331 on the convex edge 210 to move away from the hatch cover, so that the inclined surface 211 and the inclined edge 111 always remain in close contact.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
