[0043] Figure 1 and Figure 2 The schematic diagram of the structure of the battery box 1a in some embodiments of the utility model is shown. The battery box 1a includes a storage device 10, which is used to store and install other components. The storage device 10 includes a storage component 1, a cover component 2 and a connection component 3. It can be understood that the storage component 1 plays a role of storage. The cover component 2 plays a role of covering and sealing the storage component 1. The connection component 3 plays a role of connecting the cover component 2 and the storage component 1.

[0044] like Figures 2 to 5 As shown, the storage assembly 1 includes a storage box 11 , which is provided with an opening 111 and a storage cavity 112 , the opening 111 is communicated with the storage cavity 112 , and each edge of the opening 111 is bent inwardly to form a sealed inner fold 113 .

[0045] It can be understood that the storage box 11 serves to store other parts. Specifically, the parts can be assembled in the storage cavity 112 or on the side wall of the storage box 11. The storage cavity 112 can be opened through the opening 111 for assembly production or maintenance. The sealed inner fold 113 is a continuous ring as a whole. The sealed inner fold 113 can be configured to be made by bending. The bending process can be processed by common sheet metal processing equipment in the prior art.

[0046] Each position of the opening 111 is subjected to a bending process, and the bent portion is bent inwardly to form a sealed inner fold 113, so that the bent portion can be prevented from being exposed outside the storage box 11, thereby improving the overall consistency of the product appearance.

[0047] It should be noted that the storage box 11 can be configured to be formed by connecting a plurality of plate-like structures, and the specific connection methods include welding, screwing, clamping or bonding, etc., which are common connection structures in the prior art. The storage box 11 can also be configured to be formed by bending the same plate-like structure. Of course, the storage box 11 can also be provided with reinforcing ribs or related structures with functions similar to reinforcing ribs to improve the strength and durability of the storage box 11.

[0048] like Figure 2 , Figure 5 and Figure 6 As shown, the covering assembly 2 includes a cover plate 21 and a sealing member 22 . Each edge of the cover plate 21 is provided with a sealing edge 211 . Each sealing edge 211 is provided on the cover plate 21 to form a avoiding groove 212 . The sealing member 22 is arranged in the avoiding groove 212 .

[0049] It can be understood that the cover plate 21 is in the shape of a plate as a whole, and serves to detachably shield the opening 111. The seal 22 is used to seal the mating position of the opening 111 and the cover plate 21. The sealing edge 211 is formed by bending various parts of the edge of the cover plate 21. The avoidance groove 212 serves to accommodate the seal 22. Of course, the seal 22 can also be configured to be set on the sealing inner fold 113.

[0050] like Figure 2 As shown, the connection assembly 3 includes a plurality of connection members 31, each connection member 31 is respectively passed through the cover plate 21 and the sealing edge 211, each connection member 31 is respectively connected to the storage box 11, each sealing edge 211 is supported on the sealing inner folding edge 113, and the sealing member 22 is clamped between the cover plate 21 and the sealing inner folding edge 113.

[0051] It can be understood that the connector 31 is used to pass through the cover plate 21 and connect to the storage box 11 , thereby fixing the cover plate 21 on the storage box 11 .

[0052] Furthermore, the position of the connector 31 on the cover plate 21 can be arranged to correspond to the position of the seal 22 , so that the pressing force of the connector 31 can be directly transmitted to the seal 22 , thereby ensuring the sealing strength.

[0053] Preferably, the sealing inner fold edge 113 is preferably configured to be formed by the side wall at the opening 111 after a 90° bending process. The sealing inner fold edge 113 arranged at 90° at the opening 111 can be supported on the sealing member 22 as parallel to the sealing member 22 as possible, so that the force between the sealing inner fold edge 113 and the sealing member 22 is more even, thereby further improving the sealing performance.

[0054] Preferably, the sealing edge 211 is configured as a dead edge structure, which can effectively eliminate the gap between the surface of the cover plate 21 and the sealing edge 211, so that the sealing edge 211 can be directly supported by the cover plate 21, so that the holding force transmitted to the cover plate 21 due to the fixation of the connecting piece 31 can be directly transmitted to the sealing edge 211, so that the seal 22 can be fully held, thereby further improving the sealing of the product.

[0055] like Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments of the storage device 10 , the outer edge of the sealing member 22 is in contact with or against the inner edge of each sealing inner fold edge 113 .

[0056] It can be understood that the outer contour and size of the seal 22 are compatible with the outer contour and size of each sealing inner fold 113. Specifically, after the seal 22 is correspondingly assembled in the avoidance groove 212, the outer edge of the seal 22 will be correspondingly supported on each groove wall of the avoidance groove 212, that is, the groove wall of the avoidance groove 212 is in contact with the outer edge of the seal 22 at all locations, that is, the outer edge of the seal 22 will be closely attached to the outer edge of each sealing inner fold 113. In this way, the tightness of the seal 22 and each sealing inner fold 113 can be effectively improved, and the sealing performance can be improved.

[0057] like Figure 5 As shown, in some embodiments of the storage device 10 , the sum of the width W1 of the sealing member 22 and the width W2 of the sealing edge 211 is greater than or equal to the width W3 of the sealing inner fold 113 .

[0058] It can be understood that W1+W2≥W3; in this way, it can be ensured that the sealing pressure edge 211 can completely seal the gap between the cover plate 21 and the sealing inner fold edge 113. Specifically, the sealing between the sealing cover plate 21 and the sealing inner fold edge 113 depends on the surface support of the sealing pressure edge 211 and the sealing inner fold edge 113, while the part of the sealing inner fold edge 113 that is not supported by the sealing inner fold edge 113 will be fully supported and sealed by the sealing member 22, thereby increasing the contact area between the sealing member 22 and the sealing inner fold edge 113 as much as possible, thereby achieving sufficient sealing.

[0059] During actual use, when a large amount of dust or liquid impacts the matching position of the storage box 11 and the cover 21, the foreign matter will be primarily isolated by the sealing edge 211 and the sealing inner fold 113 that support each other. Even if some foreign matter further penetrates through the matching position of the sealing edge 211 and the sealing inner fold 113, it will be blocked by the seal 22; in this way, the protection level of the product is effectively improved.

[0060] Preferably, the outer edge of the seal 22 contacts or presses against the inner edge of each sealing inner fold 113 , and the width of the seal 22 and the width of the sealing edge 211 are greater than or equal to the width of the sealing inner fold 113 .

[0061] It can be understood that the content and related beneficial effects of this embodiment can refer to the content of the aforementioned embodiments, and will not be repeated here. The content of this embodiment can further improve the protection level of the product.

[0062] like Figure 2 and Figure 5 As shown, in some embodiments of the storage device 10 , the outer edge of the sealing inner fold edge 113 is aligned with the outer edge of the sealing press edge 211 .

[0063] It can be understood that by aligning the outer edge of the sealing inner fold 113 with the outer edge of the sealing edge 211, the outer wall of the storage box 11 can be aligned with the peripheral edge of the sealing edge 221, so that after the storage box 11 and the cover plate 21 are assembled, a high degree of flatness can be maintained on the surface, that is, the formation of steps or step-like structures after the storage box 11 and the cover plate 21 are assembled is avoided, thereby improving the surface consistency of the product.

[0064] like Figure 2 As shown, in some embodiments of the storage device 10, each connecting member 31 includes a bolt, a plurality of connecting holes 213 are opened on the cover plate 21, each connecting hole 213 is penetrated by a sealing edge 211, each bolt is penetrated by each connecting hole 213 one by one, and each bolt is screwed to the storage box 11.

[0065] It can be understood that bolts include various components or structures connected by threads in the prior art. It should be noted that the position of the connection holes 213 on the cover plate 21 can be flexibly set, and it is preferred that the connection holes 213 are configured to be symmetrically arranged on the cover plate 21, so as to avoid insufficient sealing of the cover plate 21 due to the lack of bolts in some parts, thereby improving the sealing of the product.

[0066] like Figure 2 As shown, in some embodiments of the storage device 10 , each connection assembly 3 further includes a closed-hole nut 32 , each closed-hole nut 32 is disposed on the sealing inner fold 113 , and each bolt is threadedly connected to each closed-hole nut 32 one by one.

[0067] It can be understood that a threaded hole is formed on the closed-hole nut 32, but the threaded hole is a blind hole, which can prevent pollutants from entering the receiving cavity 112 through the threaded hole. The number of closed-hole nuts 32 is equal to the number of bolts.

[0068] like Figure 2As shown, in some embodiments of the storage device 10 , a plurality of countersunk holes 214 are formed on the cover plate 21 , and each connection hole 213 is located at the bottom of each countersunk hole 214 in a one-to-one correspondence.

[0069] It can be understood that the setting of the countersunk hole 214 can prevent the connector 31 from protruding out of the countersunk hole 214 after being assembled in the connecting hole 213, thereby improving the surface consistency of the product after assembly, and also plays a role in protecting the connector 31.

[0070] like Figure 6 As shown, in some embodiments of the storage device 10, a plurality of avoidance notches 221 are provided on the outer edge of the sealing member 22, and each of the avoidance notches 221 corresponds to each other for each bolt to pass through.

[0071] It can be understood that the avoidance notch 221 is used for the connector 31 to pass through. In this way, the opening of the avoidance notch 221 allows the assembly position of the connector 31 to be closer to the seal 22, thereby improving the clamping force of the cover plate 21 and the sealing inner fold 113 on the seal 22, thereby improving the sealing. Secondly, since the avoidance notch 221 is only located at the outer edge of the seal 22, that is, it is avoided to open a hole on the seal 22 for the connector 31 to pass through, the structural strength of the seal 22 is guaranteed. In addition, the connection part 31 is located between the sealing edge 211 and the seal 22, so that the fastening force of the connector 31 can also effectively act on the sealing inner fold 113 and the sealing edge 211, thereby improving the matching sealing of the sealing inner fold 113 and the sealing edge 211.

[0072] like Figure 1 and Figure 2 As shown, in some embodiments of the storage device 10, the storage device 10 also includes a lifting assembly 4, the lifting assembly 4 includes a fixed seat 41, a waterproof ring and a handle 43, the fixed seat 41 is inserted into the storage box 11, the waterproof ring is sleeved on the fixed seat 41, the waterproof ring is clamped on the fixed seat 41 and the storage box 11, and the handle 43 is rotatably set on the fixed seat 41.

[0073] It can be understood that the lifting assembly 4 is used for users to carry the battery box 1a. The fixing seat 41 is used to fix the handle 43, and the two can be connected by a rotating connection mechanism, such as a latch, a rotating bearing or other rotating connection structures in the prior art. The waterproof ring is used to prevent pollutants from penetrating through the matching gap between the fixing seat 41 and the storage box 11, thereby ensuring the sealing. The handle 43 is used for users to carry it. It should be noted that the number of the lifting assemblies 4 can be configured as two or more.

[0074] like Figure 3 and Figure 4As shown, in some embodiments of the storage device 10, the sealing member 22 includes a foamed silicone pad. It can be understood that the foamed silicone pad is a prior art, has a certain sealing property, and can fill the fitting gap by deforming under force to achieve sealing.

[0075] like Figure 5 As shown, in some embodiments of the storage device 10 , the thickness H1 of the sealing member 22 is greater than the depth of the avoidance groove 212 .

[0076] It can be understood that the thickness of the seal 22 referred to in this embodiment refers to the thickness of the seal 22 when it is not pressed. The thickness of the seal 22 is greater than the depth of the avoidance groove 212, so that the seal 22 always has a certain surplus relative to the depth of the avoidance groove 212, that is, it is ensured that the thickness of the seal 22 is greater than the height of the sealing pressure edge 211, thereby further ensuring that the seal 22 can maintain sufficient compression between the cover plate 21 and the sealing inner fold edge 113, thereby ensuring sufficient sealing.

[0077] like Figures 1 to 4 As shown, in some embodiments, the battery box 1a further includes a battery module 20 and a circuit board 30 . The battery module 20 and the circuit board 30 are respectively disposed in the storage box 11 , and the battery module 20 is electrically connected to the circuit board 30 .

[0078] It is understandable that the battery box 1a can be used alone, or multiple battery boxes 1a can be used in combination. The storage device 10 is used to install the battery module 20 and the circuit board 30. The battery module 20 is configured to be connected by multiple single cells, and the battery module 20 is a prior art. The number of single cells contained in the battery module 20 and the arrangement of each single cell can be flexibly set. The circuit board 30 is used to control the operation of the corresponding electrical components and is also used to receive the current transmitted from the battery module 20.

[0079] like Figure 3 and Figure 4 As shown, in some embodiments of the storage device 10, the battery box 1a further includes a display device 40, and the display device 40 includes a display circuit board 50, a display light and a light-transmitting lens 60;

[0080] A reinforcing plate 114 is provided on the inner wall surface of the storage cavity 112, a mounting groove 115 is provided on the storage box 11, at least one light-transmitting hole 116 is provided at the bottom of the mounting groove 115, the light-transmitting hole 116 passes through the reinforcing plate 114, the display circuit board 50 is provided on the reinforcing plate 114, the display light is provided on the display circuit board, the display light is aligned with the light-transmitting hole 116, and the light-transmitting lens 60 is provided in the mounting groove 115.

[0081] It can be understood that the display device 40 is used to feed back corresponding information to the user or staff. The display circuit board 50 is used to control the operation of the corresponding display light, and the display light is used to emit light during the operation process. The light-transmitting lens 60 is used to allow the light emitted by the display light to pass through, so as to achieve the purpose of prompting the user or staff.
