DETAILED DESCRIPTION

[0056] In order to enable the above-mentioned purpose, features and advantages of the present application to be more clearly understood, the present application will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0057] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be practiced in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0058] The following description will be made with reference to the drawings. Figures 1 to 16The energy storage box and the energy storage device according to some embodiments of the present application are described.

[0059] According to one embodiment of the first aspect of the present application, as shown in Figures 1 to 16 The first aspect of the present application proposes an energy storage box 10, which comprises a box body 100 and a box cover 101, the box body 100 comprises a containing cavity 1002 with an opening. The box cover 101 is installed on the box body 100 and can slide between an unlocking position and a locking position. A buckle structure 102 is arranged on the box cover 101, and a clamping hole 103 is arranged on the box body 100. When the box cover 101 is in the locking position, the buckle structure 102 cooperates with the clamping hole 103, and is used for sealing the containing cavity 1002.

[0060] The energy storage box 10 provided by the present application comprises a box body 100 and a box cover 101, as shown in Figure 11 The box body 100 comprises a containing cavity 1002 with an opening, the box cover 101 is installed on the box body 100, and can slide relative to the box body 100 between an unlocking position and a locking position (as shown in Figure 1 、 Figure 2 and Figure 3 When the box cover is in the unlocking position, as shown in Figure 4 、 Figure 5 and Figure 6As shown, the lid is in the locked position, thus sealing the receiving cavity 1002. Specifically, a snap-fit ​​structure 102 can be provided on the lid 101, and a snap-fit ​​hole 103 can be provided on the body 100. The snap-fit ​​structure 102 cooperates with the snap-fit ​​hole 103 to seal the receiving cavity 1002. It can be understood that when the lid 101 is in the unlocked position, the snap-fit ​​structure 102 does not cooperate with the snap-fit ​​hole 103, so the lid 101 can be removed or opened. When the lid 101 is in the locked position, the snap-fit ​​structure 102 cooperates with the snap-fit ​​hole 103, so that the lid 101 can be fixed on the body 100 to seal the receiving cavity 1002. In this field, energy storage boxes 10 typically contain precision electronic components, requiring high levels of insulation and waterproofing. Therefore, related technologies typically use multiple bolts to fix the cover 101 to the box body 100, ensuring a tight seal between the cover 101 and the box body 100. However, the need for multiple bolts increases the overall assembly time and reduces production efficiency. This application, however, only requires installing the cover 101 onto the box body 100, allowing the snap-fit ​​structure 102 to pass through the snap-fit ​​hole 103, and then sliding the cover 101 to the locked position. This allows the snap-fit ​​structure 102 to snap onto the box body 100, thus securing the cover 101. Therefore, compared to related technologies, this improves assembly efficiency and increases production efficiency. Furthermore, by using the snap-fit ​​hole 103 to engage with the snap-fit ​​structure 102, the snap-fit ​​structure 102 remains in place, improving the installation efficiency and stability of the energy storage box 10.

[0061] In some embodiments, optionally, the length of the latching structure 102 passing through the latching hole 103 when the lid 101 is in the unlocked position is less than the length of the latching structure 102 passing through the latching hole 103 when the lid 101 is in the locked position.

[0062] In these embodiments, since the snap-fit ​​structure 102 is installed on the lid 101 and the length of the snap-fit ​​structure 102 protruding from the lid 101 is fixed, the longer the snap-fit ​​structure 102 passes through the snap-fit ​​hole 103, the tighter the fit between the lid 101 and the box body 100, and the smaller the gap between the lid 101 and the box body 100. Therefore, by limiting the length of the snap-fit ​​structure 102 passing through the snap-fit ​​hole 103 when the lid 101 is in the unlocked position to be less than the length of the snap-fit ​​structure 102 passing through the snap-fit ​​hole 103 when the lid 101 is in the locked position, the lid 101 and the box body 100 can fit more tightly when the lid 101 is in the locked position, thereby improving the sealing effect.

[0063] Among them, such as Figure 3 and Figure 6 As shown, Figure 3L1 represents the length of the buckle structure 102 passing through the clamping hole 103 when the box cover 101 is in the unlocking position. Figure 6 L2 represents the length of the buckle structure 102 passing through the clamping hole 103 when the box cover 101 is in the locking position, and L1 is less than L2.

[0064] In some embodiments, the width of the clamping hole 103 gradually decreases in the direction from the unlocking position to the locking position.

[0065] In some embodiments, the clamping hole 103 can be arranged such that the width of the clamping hole 103 gradually decreases in the direction from the unlocking position to the locking position, as indicated by the direction P. Figure 12 In some embodiments, the width of the clamping hole 103 gradually decreases in the direction from the unlocking position to the locking position, as indicated by the direction P.

[0066] In some embodiments, the cross section of the clamping hole 103 can be trapezoidal, as shown in FIGS. 7 and 8. Figure 12 and Figure 13 In some embodiments, the cross section of the clamping hole 103 can be trapezoidal, as shown in FIGS. 7 and 8.

[0067] In some embodiments, the cross section of the clamping hole 103 can be trapezoidal, as shown in FIGS. 7 and 8.

[0068] In some embodiments, the cross section of the clamping hole 103 can be cam-shaped.

[0069] In some embodiments, the energy storage box 10 further comprises a guiding structure 104 arranged on the buckle structure 102, for guiding the box cover 101 when sliding from the unlocking position to the locking position.

[0070] In the embodiments, in order to facilitate the sliding of the box cover 101, a guide structure 104 can be arranged on the buckle structure 102 to guide the sliding of the box cover 101 from the unlocking position to the locking position, thereby improving the installation efficiency and assembly convenience of the energy storage box 10.

[0071] In some embodiments, optionally, the guide structure 104 comprises a guide surface 1042, which is arranged in a direction from the unlocking position to the locking position and is inclined along the depth direction of the clamping hole 103.

[0072] In the embodiments, the guide surface 1042 can be arranged to guide the sliding of the box cover 101 from the unlocking position to the locking position. Specifically, the guide surface 1042 is arranged in a direction from the unlocking position to the locking position and is inclined along the depth direction of the clamping hole 103 (i.e., the direction indicated by the arrow M), that is, the guide surface 1042 is a slope surface. Thus, when the box cover 101 is slid from the unlocking position to the locking position, the slope guide surface 1042 can be used to guide the sliding of the box cover 101, so that the box cover 101 is more easily slid to the locking position. Figure 6

[0073] In some embodiments, optionally, as shown in Figure 8 and Figure 10 , the buckle structure 102 is riveted to the box cover 101.

[0074] In the embodiments, the buckle structure 102 can be riveted to the box cover 101, which can greatly improve the assembly efficiency of the energy storage box 10, thereby improving the production efficiency.

[0075] In some embodiments, optionally, as shown in Figure 10 , Figure 14 and Figure 15 , the box cover 101 is provided with a mounting groove 1012, and the buckle structure 102 comprises a riveting portion 1022 riveted to the mounting groove 1012 and a riveting groove 1024 arranged on the riveting portion 1022 along the circumferential direction of the mounting groove 1012 and used to accommodate part of the structure of the box cover 101 when the riveting portion 1022 is riveted to the mounting groove 1012.

[0076] In the embodiments, the mounting groove 1012 can be arranged on the box cover 101, and the riveting portion 1022 can be arranged on the buckle structure 102, so that the riveting portion 1022 and the mounting groove 1012 can be riveted. In order to improve the stability of the riveting, the riveting groove 1024 can also be arranged on the riveting portion 1022, so that the riveting groove 1024 is arranged along the circumferential direction of the mounting groove 1012. Thus, when the riveting portion 1022 is riveted to the mounting groove 1012, the material around the mounting groove 1012 can be extruded into the riveting groove 1024, thereby improving the stability of the riveting.

[0077] ​In some embodiments, the snap-fit ​​structure 102 is optionally welded to the lid 101.

[0078] In these embodiments, the snap-fit ​​structure 102 can also be welded to the cover 101. The welding is more stable and helps to improve the service life of the energy storage box 10.

[0079] In some embodiments, the snap-fit ​​structure 102 is optionally attached to the lid 101.

[0080] In these embodiments, the snap-fit ​​structure 102 can also be glued to the box cover 101, which is faster and can also improve production efficiency.

[0081] In some embodiments, the energy storage box 10 may optionally include a sealing member 105 disposed on the box body 100 and located between the box body 100 and the box cover 101, wherein when the box cover 101 is in the locked position, the box cover 101 presses against the sealing member 105.

[0082] In these embodiments, to further ensure sealing, a sealing element 105 can be provided on the housing 100, such that the sealing element 105 is located between the housing 100 and the lid 101, so that when the lid 101 slides to the locked position, the sealing element 105 is squeezed to achieve a seal between the housing 100 and the lid 101.

[0083] In some embodiments, the seal 105 may optionally be a sealing ring.

[0084] In some embodiments, the seal 105 may optionally be a sealing strip.

[0085] In some embodiments, optionally, such as Figure 7 , Figure 9 and Figure 16 As shown, the energy storage box 10 also includes: a through hole 1014, which is provided on the box cover 101; and a threaded hole 1016, which is provided on the box body 100 and is provided opposite to the through hole 1014.

[0086] In these embodiments, a through hole 1014 can be provided on the cover 101, and a threaded hole 1016 can be provided on the body 100. This allows the fixing bolts to engage with the threaded holes 1016, thus securing the body 100 and the cover 101 and preventing the snap-fit ​​structure 102 on the cover 101 from disengaging from the body 100, thereby improving the stability of the engagement. Specifically, the fixing bolts are passed through the through hole 1014 on the cover 101 and screwed into the threaded hole 1016 for fixation.

[0087] In some embodiments, the energy storage box 10 may optionally include at least one fixing bolt, which is used to engage with the threaded hole 1016 through the through hole 1014 when the box cover 101 is in the locked position.

[0088] In the embodiments, at least one fixing bolt can be arranged to further fix the box body 100 and the box cover 101. Specifically, when the box cover 101 is in the locking position, the fixing bolt is arranged on the box body 100 and the box cover 101, so as to fix the box body 100 and the box cover 101, prevent the buckle structure 102 on the box cover 101 from being disengaged from the box body 100, and improve the stability of the cooperation. The box cover 101 of the application adopts the buckle structure 102 plus the fixing bolt, and 80% of the bolts are saved.

[0089] In some embodiments, the fixing bolt is arranged in three.

[0090] In some embodiments, the arrangement direction of the fixing bolt can be arranged according to actual needs, as long as the box cover 101 and the box body 100 can be connected.
