Description

Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to a support device and energy storage equipment. Background Technology

[0002] With the rapid development of energy storage technology and the popularization of distributed photovoltaic systems, household energy storage batteries, as important devices for achieving energy self-generation and self-consumption, peak shaving and valley filling, and emergency backup power, have been widely used in homes, small commercial spaces, and off-grid systems. Users have placed higher demands on the installation flexibility, spatial adaptability, and ease of use of energy storage devices.

[0003] Currently, most mainstream home energy storage batteries on the market adopt wall-mounted installation to save floor space and improve overall aesthetics. However, traditional wall-mounted structures typically only support a single fixed installation direction (such as vertical wall mounting), and their installation interfaces and mechanical structure designs lack directional adaptability, failing to meet various installation needs such as horizontal, inverted, or lateral mounting. This design limitation leads to significant space adaptation challenges in practical applications, making it difficult to find wall locations that meet traditional installation requirements, severely restricting the deployment flexibility of the equipment. Utility Model Content

[0004] This application aims to provide a support device and energy storage equipment for energy storage devices, with the goal of improving the flexibility and space adaptability of energy storage equipment installation.

[0005] In a first aspect, this application proposes a support device, including a support frame and a hanger. Along a first direction, the support frame includes a first support member and a third support member disposed opposite to each other. The first support member has a first engagement portion on the side facing the third support member, and the first engagement portion includes a first engagement space. The third support member has a third limiting opening, which is disposed opposite to the first engagement space. Along a second direction, the support frame includes a second support member and a fourth support member disposed opposite to each other. The second support member has a second engagement portion on the side facing the fourth support member, and the second engagement portion includes a second engagement space. The fourth support member has a fourth limiting opening, which is disposed opposite to the second engagement space. The first and second directions are perpendicular to each other. The hanger includes a frame plate, a hanging arm, and a snap-fit ​​component. The hanging arm and the snap-fit ​​component are disposed opposite to each other on the frame plate. The hanging arm is configured to snap-fit ​​with the first engagement portion within the first engagement space, and the snap-fit ​​component snap-fits with the third limiting opening. Alternatively, the hanger arm is configured to engage with the second engagement part within the second engagement space, and the engaging member engages with the fourth limiting port.

[0006] In the above scheme, the mounting bracket is fixedly connected to the wall, and the support frame is connected to the energy storage device and mounted on the mounting bracket. The mounting bracket provides stable support for the support frame and the energy storage device. The first engagement part and the third limiting port of the support frame can cooperate with the hanging arm and the snap-fit ​​of the mounting bracket to engage, allowing the energy storage device to be stably mounted on the wall. The second engagement part and the fourth limiting port of the support frame can also cooperate with the hanging arm and the snap-fit ​​of the mounting bracket to engage, allowing the energy storage device to be mounted on the wall in different orientations. With the mounting bracket as a reference frame, the direction in which the hanging arm extends towards the snap-fit ​​is the third direction, and the direction perpendicular to the third direction is the fourth direction. It can be understood that the third direction may be parallel to and in the same direction as the first direction, or it may be parallel to and in the opposite direction to the first direction. The fourth direction may be parallel to and in the same direction as the second direction, or it may be parallel to and in the opposite direction to the second direction. For example, the connection port of the energy storage device may face the third direction or the opposite direction of the third direction, or it may face the fourth direction or the opposite direction of the fourth direction. The above-mentioned structural design of the support components allows for more flexible installation of energy storage devices, better adaptability to different installation spaces, and improved flexibility, convenience, and spatial adaptability of energy storage device installation.

[0007] In some embodiments, a third mounting portion is provided on the side of the third support member facing the first support member, and the third mounting portion includes a third mounting space. The first support member has a first limiting opening, which is disposed opposite to the third mounting space. A fourth support member has a fourth mounting portion on the side of the fourth support member facing the second support member, and the fourth mounting portion includes a fourth mounting space. The second support member has a second limiting opening, which is disposed opposite to the fourth mounting space. By providing the third and fourth mounting portions on the third and fourth support members, and by providing the first and second limiting openings on the first and second support members, the energy storage device can have more options in terms of installation direction through the cooperation of the bracket with the first and second limiting openings and the third and fourth mounting portions. Depending on the installation environment, the connection port of the energy storage device can be oriented towards a third direction, the opposite direction of the third direction, a fourth direction, or the opposite direction of the fourth direction. This improves the flexibility of installing the energy storage device.

[0008] In some embodiments, the support frame further includes a first connecting plate and a second connecting plate, which are disposed opposite to each other. The first connecting plate is connected to a first support member and extends in a direction away from the second connecting plate. The second connecting plate is connected to a third support member and extends in a direction away from the first connecting plate. The first and second connecting plates are configured to fit snugly against the energy storage device. By providing the first and second connecting plates, they can fit snugly against the energy storage device, making the connection between the energy storage device and the support frame more stable and improving the stability of the connection structure.

[0009] In some embodiments, a first engaging portion is connected between a second engaging portion and a fourth engaging portion, and a third engaging portion is connected between the second engaging portion and the fourth engaging portion. A first chamfer is provided at the connection between the first engaging portion and the second engaging portion, and a second chamfer is provided at the connection between the second engaging portion and the third engaging portion. And / or, a third chamfer is provided at the connection between the third engaging portion and the fourth engaging portion, and a fourth chamfer is provided at the connection between the fourth engaging portion and the first engaging portion. By providing chamfers at the connections of the first engaging portion, the second engaging portion, the third engaging portion, and the fourth engaging portion, the chamfers can guide the hanging bracket when the support frame and the hanging bracket are engaged, allowing for quick engagement. Furthermore, the chamfers can provide better limiting effect, improving the stability of the engagement between the support frame and the hanging bracket.

[0010] In some embodiments, the mounting plate of the bracket is provided with reinforcing ribs, the length direction of which is parallel to the direction from the hanging arm to the snap-fit. After the energy storage device is installed, the mounting plate needs to bear the weight of the energy storage device. Providing reinforcing ribs on the mounting plate can enhance its strength, increase the force that the mounting plate can withstand, and enhance the stability of the support.

[0011] In some embodiments, the hanging arm includes a first plate, a second plate, and a first reinforcing plate. The first plate abuts against the energy storage device, the second plate is connected to the frame plate, and the first plate and the second plate are connected. The first reinforcing plate is connected to the first plate and serves to support the first plate between the first plate and the first mounting portion. Providing the first reinforcing plate between the first plate and the second plate enhances the strength of the hanging arm and reduces the risk of damage due to the weight of the energy storage device, thus preventing instability during the installation of the energy storage device.

[0012] In some embodiments, the shelf plate has a plurality of mounting holes. Some mounting holes are located near the hanging arm, while others are located near the snap-fit ​​connector. Having a plurality of mounting holes on the shelf plate and installing it with fasteners improves installation convenience and structural stability. Distributing the mounting holes also disperses the fastening force, reducing the likelihood of excessive stress on the shelf plate.

[0013] In some embodiments, the mounting hole is a strip-shaped hole. Setting the mounting hole as a strip-shaped hole, with a lengthwise clearance, can reduce the impact of heat generated during energy storage device operation and thermal expansion and contraction on fasteners, thus improving installation stability.

[0014] Secondly, this application proposes an energy storage device, including an energy storage unit and a support device as described in any embodiment of the first aspect.

[0015] In some embodiments, the support device further includes a fixing plate, which comprises a third plate and a fourth plate connected together. The third plate is used to connect to the wall, and the fourth plate is used to connect to the energy storage device. By providing a fixing plate, with the third plate mounted on the wall and the fourth plate connected to the energy storage device, tensile force can be provided to the energy storage device. Combined with the support frame and hanger, this improves the stability of the energy storage device.

[0016] Additional aspects and advantages of the embodiments of this application will be described, shown, or illustrated in part by way of implementation of the embodiments of this application in the following description. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0021] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0022] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0023] The technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0024] Firstly, this application proposes a support device, please refer to... Figure 1 The bracket includes a support frame 1 and a hanger 2.

[0025] The support frame 1 can be connected to the energy storage device 10 and can be attached to the hanger 2. The support frame 1 itself has a certain strength, and its material can be a material with high tensile strength such as aluminum alloy. In addition, aluminum alloy has strong corrosion resistance, which is beneficial for adapting to relatively humid working environments. The lightweight nature of aluminum alloy can also reduce the weight borne by the hanger 2.

[0026] After the energy storage device 10 and the support frame 1 are attached to the aforementioned bracket 2, the bracket 2 can bear part of the weight of the energy storage device 10. The bracket 2 can also be made of materials with high strength and rigidity, such as stainless steel or carbon steel. These materials can reduce the deformation of the bracket 2 during long-term use, thereby providing stable and reliable support for the energy storage device 10 and reducing the risk of the energy storage device 10 tilting or even falling off due to deformation.

[0027] Please refer to Figures 3 to 5 Along the first direction X, the support frame 1 includes a first support member 11 and a third support member 13 disposed opposite to each other. The first support member 11 has a first engaging portion 111 on the side facing the third support member 13, and the first engaging portion 111 includes a first engaging space 1111. The third support member 13 has a third limiting opening 132, which is disposed opposite to the first engaging space 1111. Along the second direction Y, the support frame 1 includes a second support member 12 and a fourth support member 14 disposed opposite to each other. The second support member 12 has a second engaging portion 121 on the side facing the fourth support member 14, and the second engaging portion 121 includes a second engaging space 1211. The fourth support member 14 has a fourth limiting opening 142, which is disposed opposite to the second engaging space 1211. The first direction X and the second direction Y are perpendicular to each other. The hanger 2 includes a frame plate 21, a hanging arm 22, and a locking member 23, with the hanging arm 22 and the locking member 23 disposed opposite to each other on the frame plate 21. The hanging arm 22 is configured to engage with the first engaging part 111 within the first engaging space 1111, and the locking member 23 engages with the third limiting port 132. Alternatively, the hanging arm 22 is configured to engage with the second engaging part 121 within the second engaging space 1211, and the locking member 23 engages with the fourth limiting port 142.

[0028] In the above scheme, the bracket 2 can be fixedly connected to the wall, and the support frame 1 is connected to the energy storage device 10 and mounted on the bracket 2. The bracket 2 provides stable support for the support frame 1 and the energy storage device 10. The first engagement part 111 and the third limiting port 132 of the support frame 1 can cooperate with the hanging arm 22 and the snap-fit ​​part 23 of the bracket 2 to engage, so that the energy storage device 10 can be stably mounted on the wall. The second engagement part 121 and the fourth limiting port 142 of the support frame 1 can also cooperate with the hanging arm 22 and the snap-fit ​​part 23 of the bracket 2 to engage, so that the energy storage device 10 can be mounted on the wall in different orientations. Taking the bracket 2 as a reference frame, the direction in which the hanging arm 22 extends toward the snap-fit ​​part 23 is the third direction Z, and the direction perpendicular to the third direction Z is the fourth direction W. It can be understood that the third direction Z may be parallel to and in the same direction as the first direction X, or it may be parallel to and in the opposite direction to the first direction X. The fourth direction W may be parallel to and in the same direction as the second direction Y, or it may be parallel to the second direction Y but in the opposite direction. For example, please refer to... Figures 10 to 13 This allows the connection port P of the energy storage device 10 to face the same direction as the third direction Z or the fourth direction W, or the opposite direction of the third direction Z or the opposite direction of the fourth direction W. Through the above structural design of the support components, energy storage devices can be installed more flexibly, better adapting to different installation spaces, and improving the flexibility, convenience, and spatial adaptability of energy storage device installation.

[0029] In some embodiments, please refer to Figure 2 and Figure 3 The third support member 13 has a third engaging portion 131 on the side facing the first support member 11, and the third engaging portion 131 includes a third engaging space 1311. The first support member 11 has a first limiting opening 112, which is opposite to the third engaging space 1311. The fourth support member 14 has a fourth engaging portion 141 on the side facing the second support member 12, and the fourth engaging portion 141 includes a fourth engaging space 1411. The second support member 12 has a second limiting opening 122, which is opposite to the fourth engaging space 1411. A third mounting portion 131 and a fourth mounting portion 141 are provided on the third support member 13 and the fourth support member 14, respectively. A first limiting port 112 and a second limiting port 122 are provided on the first support member 11 and the second support member 12. Through the cooperation of the bracket 2 with the first limiting port 112 and the second limiting port 122, as well as the third mounting portion 131 and the fourth mounting portion 141, the energy storage device 10 can have more options in terms of installation direction. For example, the connection port of the energy storage device 10 can be oriented towards the third direction Z, the fourth direction W, the opposite direction of the third direction Z, or the opposite direction of the fourth direction W. This improves the flexibility of installing the energy storage device 10.

[0030] In some embodiments, please refer to Figure 2 and Figure 3 The support frame 1 also includes a first connecting plate 15 and a second connecting plate 16, which are disposed opposite to each other. The first connecting plate 15 is connected to the first support member 11 and extends in a direction away from the second connecting plate 16. The second connecting plate 16 is connected to the third support member 13 and extends in a direction away from the first connecting plate 15. The first connecting plate 15 and the second connecting plate 16 are configured to fit snugly against the energy storage device 10. By providing the first connecting plate 15 and the second connecting plate 16, they can fit snugly against the energy storage device 10, making the connection between the energy storage device 10 and the support frame 1 more stable and improving the stability of the connection structure.

[0031] In some embodiments, please refer to Figure 2 and Figure 3 The first engagement part 111 connects to the second engagement part 121 and the fourth engagement part 141, and the third engagement part 131 connects to the second engagement part 121 and the fourth engagement part 141. A first chamfer 171 is provided at the connection between the first engagement part 111 and the second engagement part 121, and a second chamfer 172 is provided at the connection between the second engagement part 121 and the third engagement part 131. And / or, a third chamfer 173 is provided at the connection between the third engagement part 131 and the fourth engagement part 141, and a fourth chamfer 174 is provided at the connection between the fourth engagement part 141 and the first engagement part 111. With chamfers at the connections of the first engagement part 111, the second engagement part 121, the third engagement part 131, and the fourth engagement part 141, the chamfers can guide the hanger 2 when the support frame 1 and the hanger 2 are engaged, allowing for quick engagement of the support frame 1 and the hanger 2. Furthermore, the chamfer can provide better limiting effect and improve the stability of the engagement of the support frame 1 and the hanger 2.

[0032] In some embodiments, please refer to Figure 4 and Figure 5 The bracket 2 has reinforcing ribs 211 on its frame plate 21, with the length of the reinforcing ribs 211 parallel to the direction from the hanging arm 22 to the snap-fit ​​member 23. It is understood that two reinforcing ribs 211 can be provided, and placing two reinforcing ribs 211 opposite each other on the frame plate 21 can better improve the strength of the frame plate 21. After the energy storage device 10 is installed, the frame plate 21 needs to bear the weight of the energy storage device 10. Providing reinforcing ribs 211 on the frame plate 21 can enhance its strength, increase the force that the frame plate 21 can withstand, and enhance the stability of the support.

[0033] In some embodiments, please refer to Figure 4 and Figure 5The hanging arm 22 includes a first plate 221, a second plate 222, and a first reinforcing plate 223. The first plate 221 abuts against the energy storage device 10, the second plate 222 connects to the frame plate 21, and the first reinforcing plate 223 connects to the first plate 221, serving as support between the first plate 221 and the first mounting portion 111. The first reinforcing plate 223, positioned between the first plate 221 and the second plate 222, enhances the strength of the hanging arm 22, reducing the risk of damage due to the weight of the energy storage device 10 and ensuring stable installation of the device. It is understood that to further improve the strength of the hanging arm 22, a second reinforcing plate 224 can be provided, with the first reinforcing plate 223 and the second reinforcing plate 224 positioned opposite each other at both ends of the first plate 221. These two reinforcing plates can further enhance the strength of the hanging arm 22.

[0034] In some embodiments, please refer to Figure 4 and Figure 5 The frame plate 21 has several mounting holes 212. Some mounting holes 212 are located near the hanging arm 22, and others are located near the snap-fit ​​connector 23. For example, three mounting holes 212 are located near the hanging arm 22, and one mounting hole 212 is located near the snap-fit ​​connector 23. By providing several mounting holes 212 on the frame plate 21 and installing the frame plate 21 with fasteners, the ease of installation and structural stability are improved. Distributing the mounting holes 212 also disperses the fastening force, reducing the possibility of excessive force on any part of the frame plate 21.

[0035] In some embodiments, please refer to Figure 4 and Figure 5 Mounting hole 212 is a strip-shaped hole. By designing mounting hole 212 as a strip-shaped hole, a sufficient clearance is provided along its length. This reduces the impact of heat generated during the operation of the energy storage device 10 and thermal expansion and contraction on the fasteners, thus improving installation stability.

[0036] In this application, the bracket 2 is fixedly installed on the wall, and the support frame 1 is connected to the energy storage device 10. Please refer to... Figures 7 to 9 After the first support member 11 and the third limiting port 132 of the support frame 1 are engaged with the hanging arm 22 and the snap-fit ​​member 23 of the hanging bracket 2, the energy storage device 10 can be mounted on the wall. At this time, please refer to... Figure 10 The orientation of connection port 101 is opposite to the Z-axis. If you need to change the installation orientation, please refer to [the relevant documentation / reference]. Figures 11 to 13To change the orientation of the connection port 101 to the fourth direction W, simply connect the second support member 12 and the fourth limiting port 142 of the support frame 1 to the hanging arm 22 and the snap-fit ​​member 23 of the hanger 2. This completes the orientation setting of the connection port 101 quickly and easily. Similarly, for other orientations, such as changing the connection port to the opposite direction of the third direction Z or the fourth direction W, simply connect the third support member 13 and the first limiting port 112 to the hanging arm 22 and the snap-fit ​​member 23 of the hanger 2, or connect the fourth support member 14 and the second limiting port 122 to the hanging arm 22 and the snap-fit ​​member 23 of the hanger 2. Through these settings, the bracket can adapt to installation environments with multiple orientations, improving the flexibility and convenience of installing the energy storage device 10.

[0037] Secondly, this application proposes an energy storage device, including an energy storage device 10 and a support device as described in any embodiment of the first aspect.

[0038] In some embodiments, please refer to Figure 6 The support device also includes a fixing plate 3, which comprises a third plate 31 and a fourth plate 32. The third plate 31 and the fourth plate 32 are connected. The third plate 31 is used to connect to the wall, and the fourth plate 32 is used to connect to the energy storage device 10. By setting the fixing plate 3, with the third plate 31 set in the wall and the fourth plate 32 connected to the energy storage device 10, the device can provide tension to the energy storage device 10. Together with the support frame 1 and the hanging bracket 2, the stability of the energy storage device 10 is improved.
