Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and in particular to a wall-mounted energy storage cabinet. Background Technology

[0002] With the popularization of new energy applications, wall-mounted energy storage cabinets are widely used in industrial, commercial, and residential settings due to their space-saving and flexible installation features. Traditional solutions often use integrated wall-mounting brackets to fix the cabinet to the wall. However, in actual production, structural cutting is required to reduce the weight of the bracket, resulting in low material utilization and significant waste of scrap materials, thus increasing production costs. Furthermore, the integrated structure is bulky, making transportation and storage extremely inconvenient. To address this, some existing wall-mounting brackets adopt a split design, connecting two independent brackets with fasteners. While this design improves the convenience of transportation and storage, it requires on-site assembly of the brackets using fasteners during installation, increasing on-site assembly steps and reducing installation efficiency. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a wall-mounted energy storage cabinet that is easy to install, has low production cost and high stability.

[0004] The technical solution adopted by this utility model to solve its technical problem is to provide a wall-mounted energy storage cabinet, comprising:

[0005] The cabinet is provided with at least two snap-fit ​​structures;

[0006] The wall-mounted assembly includes a first bracket and a second bracket. The first bracket has at least one first limiting structure that engages with the snap-fit ​​structure, and the second bracket has at least one second limiting structure that engages with the other snap-fit ​​structure. The first bracket and the second bracket are snap-fitted together. When the cabinet is mounted on the wall-mounted assembly, the bearing pressure of the first bracket is greater than that of the second bracket.

[0007] In the aforementioned wall-mounted energy storage cabinet, the length of the first limiting structure in the vertical direction is greater than the length of the second limiting structure; when the cabinet is mounted on the wall-mounted assembly, the first limiting structure abuts against at least one of the latching structures in the vertical direction, and a longitudinal gap is formed between the second limiting structure and another latching structure.

[0008] In the aforementioned wall-mounted energy storage cabinet, the first limiting structure is located on the side of the first bracket facing the cabinet body and has a first limiting part that bends upward from bottom to top. The first limiting part cooperates with the first bracket to form a first limiting groove with an upward opening. The snap-fit ​​structure includes a first snap-fit ​​structure that is detachably connected to the cabinet body. The first snap-fit ​​structure has a first snap-fit ​​part that bends downward from top to bottom. The first snap-fit ​​part and the first limiting groove form a snap-fit ​​engagement.

[0009] In the aforementioned wall-mounted energy storage cabinet, the second limiting structure is located on the side of the second bracket facing the cabinet body and has a second limiting part that bends upward from bottom to top. The second limiting part cooperates with the second bracket to form a second limiting groove with an upward opening. The snap-fit ​​structure includes a second snap-fit ​​structure that is detachably connected to the cabinet body. The second snap-fit ​​structure has a second snap-fit ​​part that bends downward from top to bottom. The second snap-fit ​​part and the second limiting groove form a snap-fit ​​engagement.

[0010] In the aforementioned wall-mounted energy storage cabinet, the first limiting portion includes a first extending edge and a first limiting edge. One end of the first extending edge is connected to the first bracket, and the other end extends upward in a vertical direction. One end of the first limiting edge is connected to the extension end of the first extending edge, and the other end abuts against the first bracket. The first limiting edge has a first opening communicating with the first limiting groove, and the first opening does not penetrate the lateral edge of the first limiting edge. The second limiting portion includes a second extending edge and a second limiting edge. One end of the second extending edge is connected to the second bracket, and the other end extends upward in a vertical direction. One end of the second limiting edge is connected to the extension end of the second extending edge, and the other end abuts against the second bracket. The second limiting edge has a second opening communicating with the second limiting groove, and the second opening does not penetrate the lateral edge of the second limiting edge. When the cabinet body is engaged on the wall-mounted assembly, the first engaging portion engages into the first limiting groove and abuts against the first limiting edge, the second engaging portion engages into the second limiting groove, and the longitudinal gap is located between the second engaging portion and the second limiting edge.

[0011] In the aforementioned wall-mounted energy storage cabinet, the first snap-fit ​​structure includes a first fixing part, the middle of which protrudes away from the cabinet body, both ends of which are attached to the surface of the cabinet body and are detachably connected to the cabinet body by fasteners, and the first snap-fit ​​part is connected to the top side of the middle of the first fixing part; the second snap-fit ​​structure includes a second fixing part, the middle of which protrudes away from the cabinet body, both ends of which are attached to the surface of the cabinet body and are detachably connected to the cabinet body by fasteners, and the second snap-fit ​​part is connected to the top side of the middle of the second fixing part.

[0012] In the aforementioned wall-mounted energy storage cabinet, the first bracket has a horizontally arranged snap-fit ​​edge on the side near the second bracket, and the snap-fit ​​edge has a snap-fit ​​groove. The snap-fit ​​groove is recessed in the horizontal direction towards the first bracket. The second bracket has a third snap-fit ​​part on the side near the first bracket that snaps into the snap-fit ​​groove. The width of the third snap-fit ​​part at one end near the first bracket is greater than the width of the snap-fit ​​groove, and the width at the other end is less than the width of the snap-fit ​​groove.

[0013] In the aforementioned wall-mounted energy storage cabinet, the first bracket is provided with at least one first mounting hole that penetrates through itself in a horizontal direction, and fasteners can pass through the first mounting hole to fix the first bracket to the load-bearing wall. The second bracket is provided with at least one second mounting hole that penetrates through itself in a horizontal direction, and fasteners can pass through the second mounting hole to fix the second bracket to the load-bearing wall.

[0014] In the aforementioned wall-mounted energy storage cabinet, the first bracket and the second bracket are each provided with at least one through hole, and the area of ​​the through hole on the first bracket is smaller than the area of ​​the through hole on the second bracket.

[0015] In the aforementioned wall-mounted energy storage cabinet, a limiting member is detachably disposed on the side wall of the cabinet body. The limiting member is provided with a first waist hole and a second waist hole. The first waist hole is aligned with the side wall of the cabinet body and is detachably connected to the cabinet body by fasteners. The second waist hole is aligned with the side wall of the first bracket and is detachably connected to the first bracket by fasteners.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] 1. In this utility model, the cabinet is provided with at least two snap-fit ​​structures. The wall-mounted assembly includes a first bracket and a second bracket. The first bracket has at least one first limiting structure that forms a snap-fit ​​engagement with the snap-fit ​​structure, and the second bracket has at least one second limiting structure that forms a snap-fit ​​engagement with another snap-fit ​​structure. The first bracket and the second bracket are snap-fitted together. When the cabinet is snapped onto the wall-mounted assembly, the bearing pressure of the first bracket is greater than that of the second bracket. This design achieves rapid assembly of the wall-mounted assembly through the snap-fit ​​connection of the first and second brackets, reducing installation steps and improving installation efficiency. At the same time, through the differential load distribution between the main and auxiliary brackets, the first bracket bears the main load, while the second bracket plays an auxiliary positioning role. Thus, without the need for fastener reinforcement, a stable connection between the brackets can be achieved simply through snap-fit, eliminating the bolt connection required in traditional structures.

[0018] 2. In this utility model, the length of the first limiting structure in the vertical direction is greater than the length of the second limiting structure. When the cabinet is mounted on the wall-mounted assembly, the first limiting structure abuts against at least one locking structure in the vertical direction, and a longitudinal gap is formed between the second limiting structure and another locking structure. This design, through the setting of the dimensional difference, ensures that the first bracket bears the main vertical load of the cabinet, realizing the main load-bearing function; the second bracket does not directly bear the vertical pressure, mainly playing a role in lateral positioning and anti-swaying, thus forming a force division of "main load-bearing, auxiliary positioning", optimizing the load distribution of the overall structure, and improving the installation reliability and structural stability.

[0019] 3. In this utility model, the limiting component is provided with a first waist hole and a second waist hole. The first waist hole is aligned with the side wall of the cabinet and is detachably connected to the cabinet by fasteners. The second waist hole is aligned with the side wall of the first bracket and is detachably connected to the first bracket by fasteners. This design not only enhances the connection rigidity between the cabinet and the wall-mounted assembly, effectively suppressing the shaking of the cabinet during operation and improving overall stability; at the same time, the waist hole structure also allows for fine-tuning during installation, compensating for positional errors caused by processing or installation.

[0031] like Figures 1 to 4 As shown, in this embodiment, a wall-mounted energy storage cabinet includes:

[0032] The cabinet 100 has at least two snap-fit ​​structures on it;

[0033] The wall-mounted assembly includes a first bracket 400 and a second bracket 500. The first bracket 400 has at least one first limiting structure 410 that engages with a snap-fit ​​structure, and the second bracket 500 has at least one second limiting structure 510 that engages with another snap-fit ​​structure. The first bracket 400 and the second bracket 500 are snap-fitted together. When the cabinet 100 is snapped onto the wall-mounted assembly, the bearing pressure of the first bracket 400 is greater than that of the second bracket 500. This design achieves rapid assembly of the wall-mounted assembly through the snap-fit ​​connection of the first bracket 400 and the second bracket 500, reducing installation steps and improving installation efficiency. At the same time, through the differentiated load distribution between the main and auxiliary brackets, the first bracket 400 bears the main load, while the second bracket 500 plays an auxiliary positioning role. Thus, a stable connection between the brackets can be achieved simply through snap-fit ​​without the need for fastener reinforcement, eliminating the bolt connection required in traditional structures.

[0034] Specifically, such as Figures 1 to 4 As shown, in this embodiment, the wall-mounted energy storage cabinet mainly consists of a cabinet 100 and a wall-mounting assembly. The cabinet 100 is used to house the energy storage unit, control module, and other electrical components, and is the main structure of the energy storage cabinet. The cabinet 100 is rectangular and includes a base 110 and a cover 120. The cover 120 is detachably mounted on the base 110 to facilitate the maintenance and repair of the internal components.

[0035] Furthermore, the base 110 has at least two snap-fit ​​structures on the side opposite to the cover 120. These snap-fit ​​structures are spaced apart along the height direction of the cabinet 100 and are used to form a snap-fit ​​engagement with the wall-mounting assembly, so that the cabinet 100 can be easily hung on or removed from the load-bearing wall.

[0036] Furthermore, the snap-fit ​​structure includes a first snap-fit ​​structure 200 and a second snap-fit ​​structure 300, both of which are detachably mounted on the base 110 of the cabinet 100. The first snap-fit ​​structure 200 is located in the upper region of the base 110 and is used to form a snap-fit ​​engagement with the first bracket 400 in the wall-mounting assembly; the second snap-fit ​​structure 300 is located in the lower region of the base 110 and is used to form a snap-fit ​​engagement with the second bracket 500. Through the vertically distributed snap-fit ​​structures, multi-point positioning of the cabinet 100 is achieved, effectively distributing the hanging load and improving the force balance and overall installation stability during the hanging process.

[0037] Preferably, the first snap-fit ​​structure 200 has two sets, arranged symmetrically on the left and right sides, and located on the same horizontal line. This symmetrical layout allows the load to be evenly distributed to the connection points on both sides when the first support 400 bears the main weight of the cabinet 100, avoiding local stress concentration and significantly improving the structural reliability of the main load-bearing connection.

[0038] Preferably, the second snap-fit ​​structure 300 is located on the central axis of symmetry of the two first snap-fit ​​structures 200, that is, on the perpendicular bisector of the line connecting the two, thus forming a stable triangular support relationship in spatial layout. This geometric arrangement not only enhances the torsional resistance of the cabinet 100 after it is installed, but also improves the rigidity and anti-sway performance of the overall structure.

[0039] In this embodiment, the first snap-fit ​​structure 200 and the second snap-fit ​​structure 300 adopt the same structural design, and both form a detachable connection with the base 110 of the cabinet 100. This connection method can be achieved by fasteners (such as screws, bolts or expansion bolts) or by using a snap-fit ​​connection structure to meet the assembly requirements under different installation scenarios.

[0040] Furthermore, the first snap-fit ​​structure 200 includes a first fixing part 220 and a first snap-fit ​​part 210. The first fixing part 220 has a U-shaped structure, with its central portion protruding horizontally away from the cabinet 100, forming a cantilever section. This design ensures that the first snap-fit ​​part 210, connected to the central portion, maintains a certain distance from the base 110, thereby preventing interference between the fasteners on both sides of the first fixing part 220 and the surface of the first bracket 400 or the load-bearing wall after the first snap-fit ​​structure 200 is engaged with the first support 400, thus ensuring the smooth installation of the cabinet 100.

[0041] Furthermore, the two ends of the first fixing part 220 are attached to the surface of the base 110 of the cabinet 100, and a first fixing hole is provided on it. A fastener passes through the first fixing hole and cooperates with the corresponding second fixing hole on the base 110 to achieve a reliable and detachable mechanical connection.

[0042] Furthermore, the first snap-fit ​​portion 210 is located above the first fixing portion 220 and is fixedly connected to the top side of the middle part of the first fixing portion 220. Preferably, the first snap-fit ​​portion 210 and the first fixing portion 220 are integrally formed structures, which are integrally processed from metal sheets through stamping and bending processes. This design not only improves the structural strength and rigidity and reduces assembly steps, but also avoids loosening or failure problems that may be caused by the connection of multiple parts, thus enhancing the reliability of the connection.

[0043] Furthermore, the end of the first latching part 210 furthest from the first fixing part 220 is bent downwards to form a downward-facing hook-shaped structure. This hook is used to align and insert into the first limiting groove 412 on the first bracket 400 during the installation of the cabinet 100, thereby achieving lateral positioning and anti-detachment functions. When the cabinet 100 is fully installed, the first latching part 210 and the first limiting groove 412 form an abutting engagement, achieving vertical limiting load-bearing and ensuring that the main vertical load can be effectively transferred to the first bracket 400.

[0044] Furthermore, the second snap-fit ​​structure 300 includes a second fixing part 320 and a second snap-fit ​​part 310. The second fixing part 320 also has a U-shaped structure, with its central portion protruding horizontally away from the cabinet 100. This creates a certain distance between the second snap-fit ​​part 310 connected to the central portion and the base 110, thereby preventing interference between the fasteners on both sides of the second fixing part 320 and the surface of the second bracket 500 or the load-bearing wall after the second snap-fit ​​structure 300 is engaged with the second bracket 500, ensuring the smooth installation of the cabinet 100.

[0045] Furthermore, the two ends of the second fixing part 320 are attached to the surface of the base 110 of the cabinet 100, and a third fixing hole is provided on it. A fastener passes through the third fixing hole and engages with the corresponding fourth fixing hole on the base 110 to achieve a reliable and detachable mechanical connection. This design not only facilitates on-site assembly and subsequent maintenance, but also supports the replacement of the snap-fit ​​structure or the upgrade and adaptation of the cabinet 100.

[0046] Furthermore, the second snap-fit ​​portion 310 is located above the second fixing portion 320 and is fixedly connected to the top side of the middle part of the second fixing portion 320. Preferably, the second snap-fit ​​portion 310 and the second fixing portion 320 are integrally formed structures, which are integrally processed from metal sheets through stamping and bending processes. This design not only improves the structural strength and rigidity and reduces assembly steps, but also avoids loosening or failure problems that may be caused by the connection of multiple parts, thus enhancing the reliability of the connection.

[0047] Furthermore, the end of the second latching part 310 furthest from the second fixing part 320 is bent downwards to form a downward-facing hook-shaped structure. This hook is used to align and insert into the second limiting groove 512 on the second bracket 500 during the installation of the cabinet 100, achieving lateral positioning and anti-detachment functions. After the cabinet 100 is fully installed, a longitudinal gap 600 is maintained between the second latching part 310 and the second limiting groove 512 to prevent it from bearing the main vertical load of the cabinet 100. At this time, the second latching structure 300 mainly bears the lateral constraint function, preventing the cabinet 100 from swaying back and forth, shifting laterally, or torsional vibrating during operation, thus playing a role in auxiliary positioning and structural stability.

[0048] In this embodiment, the wall-mounting assembly is used to detachably install the cabinet 100 onto a load-bearing wall, achieving stable suspension of the cabinet 100. It includes a first bracket 400 and a second bracket 500, both independently fixed to preset installation positions on the load-bearing wall by fasteners, forming a split-type installation structure. This design not only facilitates transportation and storage but also reduces mold complexity and material usage, which is beneficial for mass production, thereby reducing manufacturing costs.

[0049] Furthermore, the first bracket 400 is provided with at least one circular first mounting hole 430 extending horizontally through itself, for fixing the first bracket 400 to the load-bearing wall. During installation, fasteners can pass through the first mounting hole 430 to fix the first bracket 400 to the load-bearing wall. Since the first bracket 400 is the main load-bearing component, multiple first mounting holes 430 can be provided on it according to the load-bearing requirements, and they can be arranged at intervals along the length of the first bracket 400 to distribute stress and improve connection reliability.

[0050] Accordingly, the second bracket 500 is provided with at least one circular second mounting hole 530 extending horizontally through itself, through which fasteners can pass to fix the second bracket 500 to the load-bearing wall. Preferably, there are two second mounting holes 530, located at the end of the second bracket 500 away from the first bracket 400, and symmetrically arranged along the width direction of the second bracket 500. This design provides a stable support span mechanically, effectively improving the bending resistance and torsional stiffness of the second bracket 500 during the mounting and operation of the cabinet 100.

[0051] Furthermore, both the first bracket 400 and the second bracket 500 are strip-shaped plate structures. The first bracket 400, as the main load-bearing component, is horizontally arranged to bear most of the vertical load of the cabinet 100; the second bracket 500, as an auxiliary positioning component, is vertically arranged, mainly used for guiding and lateral limiting during the installation of the cabinet 100. The two are vertically connected by a mechanical snap-fit ​​mechanism, forming a spatially orthogonal connection structure that together constitutes a stable and reliable support frame. This allows for the adaptation to multiple snap-fit ​​structures on the back of the cabinet 100, enabling multi-point installation and overall fixation of the cabinet 100.

[0052] It is worth noting that the first bracket 400 and the second bracket 500 are mechanically connected by a snap-fit ​​mechanism, eliminating the need for additional screws, bolts, or other fasteners during assembly. This design not only simplifies the on-site assembly process and reduces reliance on installation tools, but also improves installation efficiency and ease of operation.

[0053] Furthermore, the first support 400 and the second support 500 are arranged in a T-shape or an inverted T-shape. Preferably, they are arranged in a T-shape. That is, the first support 400 spans the outer top of the second support 500, forming a structural form that combines a horizontal main beam and a vertical column. This layout is not only structurally stable and has reasonable stress distribution, but also facilitates the installation process by first independently fixing the first support 400 to the wall, and then installing the second support 500.

[0054] Furthermore, the first bracket 400 has a horizontally arranged strip-shaped snap-fit ​​edge 420 on the side near the second bracket 500, and this snap-fit ​​edge 420 has a U-shaped snap-fit ​​groove 421. The snap-fit ​​groove 421 is recessed horizontally towards the first bracket 400. The second bracket 500 has a third snap-fit ​​portion 520 on the side near the first bracket 400 that snaps into the snap-fit ​​groove 421. The third snap-fit ​​portion 520 is T-shaped, with its width at the end near the first bracket 400 greater than the width of the snap-fit ​​groove 421, and its width at the other end less than the width of the snap-fit ​​groove 421. During assembly, the third snap-fit ​​portion 520 of the second bracket 500 is aligned with the U-shaped snap-fit ​​groove 421 and pushed in horizontally.

[0055] In this embodiment, the first bracket 400 has at least one first limiting structure 410 on the side facing the cabinet 100, which is used to form a snap-fit ​​engagement with the first snap-fit ​​structure 200 in the upper region of the cabinet 100; the second bracket 500 has at least one second limiting structure 510 on the side facing the cabinet 100, which is used to form a snap-fit ​​engagement with the second snap-fit ​​structure 300 in the lower region of the cabinet 100. During the installation of the cabinet 100, the user lifts the cabinet 100 and aligns it with the limiting structure, and then presses it down vertically to achieve quick installation.

[0056] Furthermore, the vertical length of the first limiting structure 410 is greater than the length of the second limiting structure 510. When the cabinet 100 is mounted on the wall-mounted assembly and pressed into place, the first snap-fit ​​structure 200 and the first limiting structure 410 are fully abutted in the vertical direction, forming a stable load-bearing fit and realizing the transmission of the main vertical load. However, since the second limiting structure 510 is shorter, a certain longitudinal gap 600 is maintained between it and the corresponding second snap-fit ​​structure 300. The two do not make substantial contact and cannot transmit significant vertical force, thus making the load-bearing pressure of the first bracket 400 greater than that of the second bracket 500. This design, through the setting of the dimensional difference, ensures that the first bracket 400 bears the main vertical load of the cabinet 100 and realizes the main load-bearing function; the second bracket 500 does not directly bear the vertical pressure and mainly plays the role of lateral positioning and anti-swaying, thus forming a force division of "main load-bearing and auxiliary positioning", optimizing the load distribution of the overall structure and improving the installation reliability and structural stability.

[0057] Furthermore, the first limiting structure 410 has a first limiting part 411 that bends upward from bottom to top. The first limiting part 411 cooperates with the first bracket 400 to form a first limiting groove 412 with an upward opening, which is used to form a snap-fit ​​with the first snap-fit ​​part 210 on the cabinet 100 to realize the rapid positioning and stable suspension of the cabinet 100.

[0058] Furthermore, the first limiting part 411 includes a first extending edge 411a and a first limiting edge 411b. One end of the first extending edge 411a is fixedly connected to the first bracket 400, and the other end extends upward in a vertical direction to form a vertical section for support. One end of the first limiting edge 411b is connected to the extending end of the first extending edge 411a and extends horizontally or obliquely toward the first bracket 400, while the other end abuts against the first bracket 400, thereby forming a first limiting groove 412 with the first bracket 400 and the first limiting groove 412 with the first limiting groove 412 closed at the top. The first limiting groove 412 has good limiting performance in the vertical direction, and can accommodate the first snap-fit ​​part 210 on the cabinet 100 and achieve a stable snap-fit ​​engagement.

[0059] Preferably, the first extending edge 411a and the first bracket 400 are integrally formed by stamping and bending, which not only has high structural strength and good manufacturability, but also eliminates the need for additional assembly processes, thus helping to reduce production costs. The first limiting edge 411b extends horizontally toward the first bracket 400, forming a horizontal surface that abuts against the first snap-fit ​​portion 210, ensuring the stability of the support.

[0060] To ensure that the first latching part 210 can smoothly engage with the first limiting groove 412, a rectangular first opening 411c communicating with the first limiting groove 412 is provided on the first limiting edge 411b. During the installation of the cabinet 100, the user lifts the cabinet 100 and aligns it with the position of the first limiting groove 412, and then presses it down vertically. The first latching part 210 slides into the first limiting groove 412 through the first opening 411c. When the cabinet 100 is fully installed, the bent section of the first latching part 210 abuts against the top surface of the first limiting edge 411b, bearing the main vertical load of the cabinet 100 and preventing the cabinet 100 from falling.

[0061] Furthermore, the first opening 411c does not penetrate the lateral edge of the first limiting edge 411b, so that a stop structure is formed on both sides of the first opening 411c to restrict the lateral disengagement of the first latching part 210. This design effectively restricts the first latching part 210 inside the first limiting groove 412, preventing it from disengaging laterally from both sides. Thus, even if the equipment is subjected to vibration, impact, or external force disturbance during operation, it can effectively prevent the cabinet 100 from laterally sliding or accidentally falling off, significantly improving the safety and reliability of the connection.

[0062] Preferably, two sets of the first limiting structure 410 are provided, arranged at intervals along the length of the first bracket 400, and each corresponds one-to-one with the two first snap-fit ​​structures 200 on the cabinet 100. This design achieves a synergistic improvement in load-bearing capacity, torsional resistance, installation accuracy, and safety redundancy, and is especially suitable for hanging scenarios of cabinets 100 that are heavy or tall.

[0063] In this embodiment, the second limiting structure 510 is basically the same as the first limiting structure 410, except that the length of the second extending side 511a is less than the length of the first extending side 411a. Specifically, the second limiting structure 510 has a second limiting part 511 that bends upward from bottom to top. The second limiting part 511 cooperates with the second bracket 500 to form a second limiting groove 512 with an upward opening, which is used to form a snap-fit ​​engagement with the second snap-fit ​​part 310 on the cabinet 100 to achieve rapid positioning and stable suspension of the cabinet 100.

[0064] Furthermore, the second limiting part 511 includes a second extending edge 511a and a second limiting edge 511b. One end of the second extending edge 511a is fixedly connected to the second bracket 500, and the other end extends upward in the vertical direction to form a vertical section for support. One end of the second limiting edge 511b is connected to the extending end of the second extending edge 511a and extends horizontally or obliquely toward the second bracket 500, and the other end abuts against the second bracket 500, thereby forming a second limiting groove 512 with the second bracket 500 and the second limiting part 511 closed at the top.

[0065] To ensure that the second latching part 310 can smoothly engage with the second limiting groove 512, a rectangular second opening 511c communicating with the second limiting groove 512 is provided on the second limiting edge 511b. During the installation of the cabinet 100, the user lifts the cabinet 100 and aligns it with the position of the second limiting groove 512, and then presses it down vertically. The second latching part 310 slides into the second limiting groove 512 through the second opening 511c. When the cabinet 100 is fully installed, the bent section of the second latching part 310 maintains a longitudinal gap 600 with the top surface of the second limiting edge 511b, and there is no direct contact, thereby avoiding the transmission of vertical load and only providing a lateral limiting function.

[0066] Furthermore, the second opening 511c does not penetrate the lateral edge of the second limiting edge 511b, so as to form a stop structure on both sides of the second opening 511c for restricting the lateral disengagement of the second latching portion 310.

[0067] In this embodiment, the first support 400 and the second support 500 are each provided with at least one rectangular through hole 700 that extends horizontally through themselves. Specifically, the first support 400 is provided with two through holes 700 arranged symmetrically from left to right, and the second support 500 is provided with one through hole 700 arranged along its own length, in order to reduce the weight of the first support 400 and the second support 500.

[0068] Furthermore, the area of ​​the through hole 700 on the first support 400 is smaller than the area of ​​the through hole 700 on the second support 500. This design reduces the weight of the first support 400 and the second support 500 while ensuring that the first support 400 retains higher structural rigidity and load-bearing capacity.

[0069] Furthermore, the top of the through hole 700 of the second bracket 500 is also provided with a guide edge 540 that bends downwards, which is used to guide the second snap-fit ​​part 310 to smoothly snap into the second limiting groove 512, thereby effectively preventing the second snap-fit ​​part 310 from accidentally entering the through hole 700 on the second bracket 500, and preventing misalignment or jamming during installation.

[0070] To further improve the reliability of the connection between the wall-mounted assembly and the cabinet 100, this embodiment also includes a detachable limiting member 800 disposed on the side wall of the cabinet 100. The limiting member 800 is rectangular and has a first waist hole 810 and a second waist hole 820. The first waist hole 810 is aligned with the side wall of the cabinet 100 and is detachably connected to the cabinet 100 via fasteners. The second waist hole 820 is aligned with the side wall of the first bracket 400 and is detachably connected to the first bracket 400 via fasteners. This design not only enhances the connection strength between the cabinet 100 and the wall-mounted assembly, effectively suppressing the shaking of the cabinet 100 during operation and improving overall stability, but also allows for fine-tuning during installation to compensate for positional errors caused by processing or installation.

[0071] Furthermore, the first waist hole 810 is an elongated oval or elliptical hole extending vertically, allowing the cabinet 100 to be finely adjusted in the vertical direction relative to the limiting member 800 during installation; the second waist hole 820 is an elongated oval or elliptical hole extending horizontally, allowing adjustment of the connection position in the front-back direction. Two sets of the second waist holes 820 are provided, arranged vertically aligned to form a dual-point vertical adjustment structure, further improving the connection rigidity with the first bracket 400.

[0072] Preferably, the limiting components 800 are provided in two sets, symmetrically arranged on the left and right sides of the cabinet 100. This design further enhances the symmetry and torsional resistance of the connection, preventing the cabinet 100 from tilting or twisting due to uneven force on one side, and ensuring the long-term stability of the overall suspension system.
