[0002] Currently, most home energy storage products adopt a modular stacked structure, consisting of multiple battery boxes and other enclosures such as high-voltage boxes stacked on top of each other. Due to the weight of the enclosures, they need to be secured to prevent collapse and safety issues. However, the securing structure between the enclosures typically relies on screws and brackets, making the installation and subsequent disassembly / repair of home energy storage products cumbersome and inefficient. Furthermore, screws are easily lost during installation, causing inconvenience in assembly and disassembly. Additionally, the numerous screw holes on the enclosure surface lead to poor enclosure consistency. Summary of the Invention

[0032] To make the technical solutions and beneficial effects of this application more apparent and understandable, the technical solutions in the embodiments of this application are clearly and completely described below by listing specific examples. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0034] It should be noted that the terms "first," "second," etc., used in this application may be used to describe various elements, but these elements are not limited by these terms. These terms are used only to distinguish one element from another, and not to describe a specific order or sequence. The terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, not excluding the presence or addition of one or more other features.

[0035] This application provides a housing locking mechanism, as shown in the following embodiments. Figures 1-10 This includes button 13, fixing block 12, spring 14, and latch 11. For example... Figure 4 As shown, button 13 includes a pressing part 131, a moving part 137, a limiting part 136, and a locking part 139. Optionally, the pressing part 131 is flat, and the locking part 139 is formed on the side wall of the pressing part 131. A chamfer 1311 is provided on the pressing part 131. The moving part 137 is columnar and is formed on the back of the pressing part 131, extending along the first direction X. A spring receiving cavity 135 is formed inside the moving part 137.

[0036] Figure 2 This is a top view of a fixed block. Figure 3 for Figure 2A cross-sectional view at position CC. A button receiving cavity 128 and a fixing hole 124 are formed in the fixing block 12. The button receiving cavity 128 accommodates the moving part 137 and allows the moving part 137 to move linearly along the first direction X. The fixing hole 124 is used to fix the fixing block 12 to the housing. The housing can be an energy storage device housing. The energy storage device can be a residential energy storage device, a balcony energy storage device, a portable energy storage device, etc. The locking part 139 is used to restrict the movement of the housing along a second direction Z perpendicular to the first direction X. The first direction X is the direction of movement of the button 13 in the button receiving cavity 128 or the width direction of the fixing block 12. The second direction Z is the height direction of the housing or the thickness direction of the fixing block 12. The third direction Y is the length direction of the fixing block 12. Optionally, the opening direction of the fixing hole 124 is along the Z direction, in which case the fixing block 12 is fixed to the top surface of the housing through the fixing hole 124; or the opening direction of the fixing hole 124 is along the X direction (not shown in the figure), in which case the fixing block 12 is fixed to the side surface 103 of the housing through the fixing hole 124. The fixing hole 124 includes a bolt through hole 125 and a bolt countersunk hole 126.

[0037] One end of the spring 14 is housed in the spring receiving cavity 135, and the other end is connected to the inner wall of the button receiving cavity 128. The inner wall of the button receiving cavity 128, perpendicular to the first direction X, is provided with a spring fixing post 123 for fitting the spring 14. One end of the hook 11 is connected to the fixing block 12, and the other end is movably connected to the limiting part 136. Optionally, the hook 11 is a U-shaped rod, and the fixing block 12 is provided with a mounting groove 122. The mounting groove 122 is provided with a hook fixing hole 121 for fixing the hook 11. One end of the hook 11 extends into the hook fixing hole 121 and can rotate within it. The hook 11 can also adopt other shapes, such as L-shaped, with one end fixed to the fixing block 12 by a pin or screw, and the other end movably connected to the limiting part 136. Using the mounting groove 122 prevents the hook 11 from protruding from the upper surface of the fixing block 12, facilitating the installation of the fixing block 12.

[0038] refer to Figures 4-5 The limiting part 136 includes a compression locking position 132, an ejection locking position 133, and a slide groove 134. The slide groove 134 connects the compression locking position 132 and the ejection locking position 133. The moving part 137 moves along the first direction X in the button receiving cavity 135 as the spring 14 extends and retracts. The other end of the hook 11 moves along the slide groove 14 as the moving part 137 moves and switches between the compression locking position 132 and the ejection locking position 133, thereby realizing the retraction and ejection of the button, and thus realizing the unlocking and locking of the housing.

[0039] The limiting part 136 includes a movable cavity surrounded by a peripheral wall and a guide block 61 located in the movable cavity. The movable cavity is surrounded by a bottom wall 1362, two side walls 1365, and a top wall 1362. A sliding groove 134 surrounds the guide block 61. The top wall 1362 of the movable cavity forms a first V-shaped guide surface 1364, a pop-out locking position 133 is formed at the bottom end of the bottom wall 1362 of the movable cavity, and the bottom of the guide block forms a second V-shaped guide surface 1361. The top wall 1366 of the guide block 61 opens towards the first V-shaped guide surface, and a compression locking position 132 is formed at the bottom end of the top wall 1366 of the guide block 61. The compression locking position 132 and the bottom end of the first V-shaped guide surface are not collinear in the first direction X, and the pop-out locking position 133 and the bottom end of the second V-shaped guide surface are not collinear in the first direction X. This facilitates guiding the hook 11 to slide in a predetermined direction and prevents the hook 11 from getting stuck.

[0040] The two inclined surfaces of the first V-shaped guide surface have unequal angles of inclination relative to the first direction. Similarly, the two inclined surfaces of the second V-shaped guide surface 1361 have unequal angles of inclination relative to the first direction. This guides the other end of the hook 11 to slide more quickly in the groove 134, making its movement easier.

[0041] Back Figure 3 and Figure 4 A first rotation limiting portion 127 extending along the first direction X is formed in the button receiving cavity 128, and a second rotation limiting portion 138 extending along the first direction X is formed in the button 13. The first rotation limiting portion 127 and the second rotation limiting portion 138 are planar. The second rotation limiting portion 138 is received in the first rotation limiting portion 127 and fits against the first rotation limiting portion 127. The second rotation limiting portion is formed on the outer wall of the limiting portion 136. Optionally, the second rotation limiting portion 138 can also be a groove or protrusion formed on the surface of the moving portion 137 extending along the first direction X. Correspondingly, the first rotation limiting portion 127 is a protrusion or groove extending along the first direction X formed on the inner wall of the button receiving cavity 128. The groove accommodates the protrusion and guides the button 13 to move along the X direction in the button receiving cavity 128, preventing it from rotating in the button receiving cavity 128.

[0042] The switching process between the other end of the latch 11 and the compression latch 132 and the ejection latch 133 is as follows: Assuming the other end of the latch is initially located in the ejection latch 133, pressing the pressing part 131 causes the moving part 137 to move into the button receiving cavity 128. Correspondingly, the other end of the latch abuts against the second V-shaped guide surface 1361 of the guide block 134. Since the two inclined surfaces of the second V-shaped guide surface 1361 have unequal angles relative to the first direction X, the other end of the latch will move along the lower inclined surface of the second V-shaped guide surface 1361 to the top wall 1363. Then, releasing the pressing part 131 causes the spring to eject the moving part 137 outwards, and the other end of the latch moves down to the top surface of the guide block 134, reaching the compression latch 132. At this time, the button switches from the ejection state to the compression state.

[0043] When the button needs to be ejected, press the pressing part 131 again. The moving part 137 moves into the button receiving cavity 128. Correspondingly, the other end of the latch abuts against the first V-shaped guide surface 1364. Since the two inclined surfaces of the first V-shaped guide surface 1364 have unequal angles of inclination relative to the first direction X, the other end of the latch will move along the upper inclined surface of the first V-shaped guide surface 1364 to the top wall 1363. Then release the pressing part 131. The spring will eject the moving part 137 outward, and the other end of the latch will move down to the ejection position 133. At this time, the button switches from the compressed state to the ejected state.

[0044] The housing locking mechanism in this embodiment is used to lock the two stacked housings together to prevent them from detaching from each other. Figure 6 The possible installation method of the housing locking mechanism is shown, which is installed inside the top wall of the housing 20. A first locking hole 102 is opened on the top side wall of the housing 20 at the position corresponding to the button 13, so as to facilitate the pop-out and retraction of the button. Each housing has a bottom plate at the bottom, which forms a stacking clearance space 201 with the lower edge of the housing side wall. The stacking clearance space 201 is used to fit with the housing below. The housing locking mechanism is installed on both side walls in the first direction X of the housing. The installation method of the housing locking mechanism is as follows: one end of the spring 14 is fitted onto the spring fixing post 123 of the fixing block 12, and the other end of the spring 14 extends into the spring receiving cavity 125 of the button 13. The moving part 137 of the button is inserted into the button receiving cavity 128 of the fixing block 12, and the second rotation limiting part 138 of the button 13 is positioned between the first rotation limiting parts 127 of the fixing block 12. Press the button pressing part 131 to slide the button 13 into the button receiving cavity 128. Then, insert one end of the hook 11 into the guide rod fixing hole 121 of the fixing block 12, and place the other end of the hook 11 in the compression locking position 132 or the slide groove 134 of the limiting part 136. Release the pressing part 131, and the hook 11 hooks the button 13.

[0045] Figure 7 for Figure 6 A partial enlarged view of section C. Align the fixing hole 124 of the fixing block 12 with the positioning pin 101 on the top wall 10 of the housing. The positioning pin 101 has internal threads. Align the button 13 with the first locking hole 102. Use the bolt 15 to fix the fixing block 12 to the top wall of the housing through the bolt through hole 125, and tighten the bolt 15 so that the head of the bolt 15 sinks into the bolt countersunk hole 126 on the fixing block.

[0046] Optionally, the housing locking mechanism can also be fixed to the housing sidewall 103.

[0047] When using, first press button 13 to put the latch 11 into the compression position 132, such as... Figure 1As shown, button 13 is in the retracted state at this time, and button locking part 139 does not protrude from the side wall 103 of housing 20. The upper housing 30 is stacked on top of the lower housing 20, with the top of the lower housing 20 fitting over the bottom of the upper housing 30. A second locking hole 202 is provided at the part of the bottom of the side wall of the upper housing 30 that fits over the top of the lower housing 20. The second locking hole 202 corresponds to button 13. After the two housings are stacked, the button pressing part 131 is pressed again, and the button moving part 137 moves inward in the X direction within the button receiving cavity 128, causing the other end of the hook 11 to slide out from the compression locking position 132. Next, release button 13. As button 13 pops out, the other end of hook 11 slides along the slide groove 134 of button limiting part 136 to pop-out locking position 133. At this time, the locking part 139 of button 13 passes through the first locking hole 102 and is located in the second locking hole 202. Button 13 engages with the second locking hole 202 of the upper housing, thereby locking the upper and lower housings.

[0048] To disassemble, press the pressing part 131 of the button again. The button 13 moves inward in the X direction within the button receiving cavity 128, causing the other end of the hook 11 to slide out of the locking position 133. Then release the button 13. As the button 13 pops outward, the other end of the hook 11 slides along the sliding groove 134 of the button limiting part 136 to the compression locking position 132. At this time, the locking part 139 of the button 13 retracts into the first locking hole 102 of the lower housing, and the button 13 does not protrude from the side wall of the lower housing 20. Lifting the upper housing 30 will separate the two parts.

[0049] By incorporating a limiter in the button, it can switch between pop-up and compressed states without the need for tools. By installing a housing locking mechanism within the housing, pressing the button locks and unlocks the housing, significantly reducing the number of screws required for installation and simplifying assembly and disassembly without the need for tools. Furthermore, the button can undergo the same surface treatment as the housing, improving surface consistency.

[0050] This application also provides a housing, such as... Figure 6 , Figure 11 As shown, the housing locking mechanism, as described in the above embodiment, is installed on the top or side surface inside the housing. The housing can be the housing of an energy storage device. The energy storage device can be a residential energy storage device, a balcony energy storage device, a portable energy storage device, etc.

[0051] This application also provides a stacked housing, such as Figure 12As shown, the housing comprises two or more housings of the above embodiments stacked vertically. The bottom of the upper housing 30 is fitted onto the top of the lower housing 20. A locking hole 202 is formed in the side wall of the upper housing, and the locking part 139 of the housing locking mechanism extends and retracts within the locking hole. When the button is extended (popped out), the button locking part 139 is located in the upper housing locking hole 202, locking the stacked housings. When the button is retracted (collapsed), the button locking part 139 is located inside the lower housing, and the stacked housings are separated. By changing the button's pop-out and retracted states, the housing can be locked and unlocked, greatly reducing the number of screws required for installation, eliminating the need for disassembly tools, simplifying the disassembly and assembly of the housing, and enabling rapid disassembly and assembly. Furthermore, the button can undergo the same surface treatment process as the housing, improving the surface consistency of the housing.

[0052] Optionally, the aforementioned stacked housing is used for energy storage devices, and the housing contains electronic components such as batteries and inverters. The energy storage devices can be residential energy storage devices, balcony energy storage devices, portable energy storage devices, etc.

[0053] The relevant content of each unit in this embodiment can be referred to the relevant content of the units with the same reference numerals in any of the foregoing embodiments, and will not be repeated here.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
