Technical Field

[0001] This application relates to the field of new energy technology, and in particular to a stationary device and an energy storage device including the stationary device. Background Technology

[0002] With the shift in global energy structure and environmental awareness, renewable energy power generation has become an important development direction for the new energy industry. Energy storage devices can serve as storage carriers for the electrical energy converted from renewable energy. Energy storage devices can provide backup power for household loads, thereby improving the reliability of household power supply in the event of a grid outage. In a home, energy storage devices should occupy as little space as possible, typically using wall mounting. However, traditional fixed installations require numerous mounting brackets, resulting in significant horizontal space consumption after wall mounting. Summary of the Invention

The first end face of the second abutment is connected to the hanging part, and the second end face of the second abutment is connected to the connecting rod. The first end face and the second end face are opposite to each other. In a direction perpendicular to the first installation direction, the cross-sectional dimension of the second abutment is larger than the cross-sectional dimension of the connecting rod. The connecting rod is connected to the carrier and the battery module, and the second abutment abuts against the carrier.

[0014] In one embodiment, the first end face of the second abutment is provided with a groove surrounding the connecting rod, and a sealing part is provided in the groove, the thickness of the sealing part being greater than the depth of the groove.

[0016] In one embodiment, the end plate has a threaded hole, and the connecting part mates with the threaded hole.

[0017] In one embodiment, the threaded hole is provided on both the surface of the end plate facing the carrier and the surface facing away from the carrier.

[0018] In one embodiment, the carrier has mounting positions for mounting battery modules, the number of which corresponds to the number of battery modules.

[0019] In one embodiment, the bearing position is provided with a second type of through hole, and the connecting part passes through the second type of through hole. The position and number of the second type of through hole correspond to the number of battery cells that the bearing position can accommodate.

[0020] In one embodiment, a plug is also included to seal any vacant second-type through-hole on the bearing position.

[0021] In one embodiment, a fixing member is also included, which is spaced apart from the mounting member and passes through the carrier member and is fixedly connected to the battery module.

[0022] In one embodiment, the fastener includes a fixing rod and a third abutment connected sequentially along the first installation direction.

Because the structure of the hanging component is simple, it also eliminates the need for numerous and complex mounting brackets, thus reducing the horizontal space occupied by the entire fixing device. Simultaneously, it can shorten the force transmission path of the entire fixing device, reduce the structural strength requirements of the hanging component, thereby simplifying the structure of the fixing device, reducing its size and weight, and improving the ease of installation.

Detailed Implementation

[0041] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0042] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0043] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0044] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0046] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0047] See Figure 1 The energy storage device 20 can provide energy for household loads and can be activated to supply power during grid outages, thereby improving power supply reliability. The energy storage device 20 includes a mounting bracket 10, which allows it to be mounted on a wall for wall-mounted installation. However, existing mounting brackets require numerous supports, resulting in the device occupying a significant amount of horizontal space.

[0048] See Figure 2 An embodiment of this application provides an energy storage device 20, including a fixing device 10. The fixing device 10 includes a mounting member 100, an energy storage mechanism 200, and a hanging member 300. The mounting member 100 is used to fix it to a support such as a wall. The energy storage mechanism 200 includes a carrier member 210 and a battery module 220, with the battery module 220 disposed on the carrier member 210. The hanging member 300 includes a connecting portion 320 and a hanging portion 310, which are sequentially connected along a first installation direction, the first direction being the X-axis direction, which can also be understood as the axial direction of the hanging member 300. The connecting portion 320 connects the carrier member 210 and the battery module 220, and the hanging portion 310 is adapted to be hung on the mounting member 100.

[0049] See Figure 3 Therefore, the entire energy storage device 20 is directly mounted on the mounting component 100 via the mounting bracket 300. The mounting bracket 300 has a simple structure and eliminates the need for numerous and complex mounting brackets. This eliminates the space occupied by mounting brackets in the horizontal direction (i.e., the X-axis direction), thereby reducing the horizontal space occupied by the entire fixing device 10. In simpler terms, it reduces the thickness of the fixing device 10. On the other hand, it shortens the force transmission path of the entire device, reduces the structural strength requirements of the mounting bracket 300, and simplifies the structure of the fixing device 10 and the entire energy storage device 20, reducing their volume and weight, and improving the ease of installation of the energy storage device 20.

[0050] See Figure 4 In some embodiments, the mounting member 100 is provided with a first type of through hole 121, and the hanging part 310 is adapted to pass through the first type of through hole 121, thereby hanging the hanging part 310 on the mounting member 100. For example, the mounting member 100 includes a mounting part 110 and a protrusion 120. The protrusion 120 protrudes from the mounting part 110 and is used to fix it to the support body. The protrusion 120 is spaced apart from the support body, so that there is a clearance space 130 between the protrusion 120 and the support body.

[0051] See Figure 5 The protrusion 120 is provided with a first type of through hole 121, which penetrates the protrusion 120 along the thickness direction, so that the first type of through hole 121 is connected to the clearance space 130.

[0052] See Figure 5The first type of through hole 121 includes a first through hole 1211 and a second through hole 1212. The diameter of the first through hole 1211 is larger than the diameter of the second through hole 1212, and the first through hole 1211 and the second through hole 1212 are interconnected. The first through hole 1211 and the second through hole 1212 are arranged along a second mounting direction, which can be perpendicular to the first mounting direction. The second mounting direction is actually... Figure 2 The Z-axis direction in the diagram. In other embodiments, the first type of through hole 121 may exclude the first through hole 1211 and include only the second through hole 1212.

[0053] See Figure 8 In some embodiments, the battery module 220 includes an end plate 221 and at least one battery cell 222. The end plate 221 is disposed at both ends of the at least one battery cell 222, and the connecting portion 320 is connected to the end plate 221.

[0054] See Figure 9 The end plate 221 has a threaded hole 2211, which includes a first threaded hole 2211a. The connecting part 320 mates with the first threaded hole 2211a to achieve a threaded connection between the connecting part 320 and the end. The end plate 221 has the first threaded hole 2211a on both the surface facing the support member 210 and the surface facing away from the support member 210. This allows both opposite surfaces of the end plate 221 to contact the support member 210 and connect with the connecting part during the installation of the battery module 220. This enables the battery module 220 to be installed in both directions, facilitating the series connection of two modules. In addition, the two end plates 221 can share a single mold, thereby reducing the design and manufacturing costs of the mold and ultimately reducing the manufacturing cost of the entire fixing device 10.

[0055] See Figure 7 In some embodiments, the carrier 210 is provided with carrier positions 211, and the battery module 220 is mounted on the carrier position 211. The number of carrier positions 211 corresponds to the number of battery modules 220. For example, the number of carrier positions 211 and the number of battery modules 220 are equal, forming a one-to-one correspondence. The carrier is provided with a second type of through hole 212, which penetrates the entire carrier 210 along the thickness direction. The connecting part 320 passes through the second type of through hole 212.

[0056] See Figure 9In some embodiments, the hanging part 310 includes a hanging rod 311 and a first abutment 312. The hanging rod 311 and the first abutment 312 are connected sequentially along a first installation direction. The first end of the hanging rod 311 is connected to the first abutment 312, and the second end of the hanging rod 311 is connected to the connecting part 320. In a direction perpendicular to the first installation direction, the cross-sectional dimension of the first abutment 312 is larger than the cross-sectional dimension of the hanging rod 311. The cross-sectional dimension of the first abutment 312 may also be larger than the diameter of the second through hole 1212. During the installation of the fixing device 10, the mounting part 110 of the mounting member 100 can be fixed to a support such as a wall first; then the first abutment 312 enters the clearance space 130 through the first through hole 1211 along the first installation direction, and the hanging rod 311 will pass through the first through hole 1211; then the hanging member 300 is moved along the second installation direction, so that the hanging rod 311 enters the second through hole 1212, that is, the hanging rod 311 passes through the second through hole 1212. At this time, the first abutment 312 and the connecting part 320 are located on opposite sides in the thickness direction of the mounting member 100, and the first abutment 312 abuts against the mounting member 100. In this way, the hanging rod 311 can be hung on the mounting member 100, thereby realizing the installation of the entire energy storage device 20.

[0057] See Figure 9 When it is necessary to unload the energy storage device 20, the mounting member 300 can be moved along the second installation direction first, so that the mounting rod 311 enters the first through hole 1211 from the second through hole 1212; then the mounting member 300 can be moved along the first installation direction, so that the first abutment 312 enters the first through hole 1211 from the clearance space 130; then the first abutment 312 can be completely detached from the first through hole 1211, that is, the entire mounting member 300 can be detached from the mounting member 100; finally, the mounting member 100 can be unloaded from the wall or other support.

[0058] See Figure 10In some embodiments, the connecting portion 320 includes a connecting rod 321 and a second abutment 322, which are sequentially connected along a first mounting direction. The connecting rod 321 may be coaxially arranged with the hanging rod 311. The second abutment 322 has a first end face and a second end face located in the thickness direction, obviously, the first end face and the second end face are arranged opposite to each other. The first end face of the second abutment 322 is connected to the hanging portion 310, and the second end face of the second abutment 322 is connected to the connecting rod 321. Along a direction perpendicular to the first mounting direction, the cross-sectional dimension of the second abutment 322 is larger than the cross-sectional dimension of the connecting rod 321. The connecting rod 321 passes through the carrier 210 and the battery module 220 and is connected, and the second abutment 322 abuts against the carrier 210. For example, the connecting rod 321 can pass through the second type of through hole 212 of the carrier 210, and the connecting rod 321 mates with the first threaded hole 2211a on the end plate 221 of the battery module 220, so that the connecting rod 321 is threadedly connected to the end plate 221, thereby fixing the battery module 220 to the carrier 210. Obviously, the carrier 210 can be sandwiched between the second abutment 322 and the battery module 220, that is, the hanger 300 connects the battery module 220 and the carrier 210 to form a whole.

[0059] See Figure 10 In some embodiments, a groove 3221 is provided on the first end face of the second abutment 322. The groove 3221 can be a circular groove, making the groove 3221 a closed loop surrounding the connecting rod 321. A sealing part 330 is provided in the groove 3221. By providing the groove 3221, the installation of the sealing part 330 can be effectively limited, improving the installation efficiency and accuracy of the sealing part 330. In a natural state without pressure, the thickness of the sealing part 330 is greater than the depth of the groove 3221, causing the sealing part 330 to protrude relative to the first end face of the second abutment 322. During the installation of the hanger 300, the sealing part 330 will abut between the second abutment 322 and the carrier 210. This allows the sealing part 330 to effectively seal the second type through hole 212 and also facilitates the adjustment of the abutment pressure between the second abutment 322 and the carrier 210. For example, the sealing part 330 can be an O-ring or the like.

[0060] See Figure 11In some embodiments, the fixing device 10 may further include a fixing member 400, which is spaced apart from the hanging member 300. For example, the fixing member 400 and the hanging member 300 may be spaced apart along a second installation direction. The fixing member 400 passes through the carrier member 210 and is fixedly connected to the battery module 220. By providing the fixing member 400, the connection strength between the battery module 220 and the carrier member 210 can be further improved. The fixing member 400 includes a fixing rod 410 and a third abutment 420. The fixing rod 410 and the third abutment 420 are connected sequentially along a first installation direction. In a direction perpendicular to the first installation direction, the cross-sectional dimension of the third abutment 420 is larger than that of the fixing rod 410. The fixing rod 410 passes through the carrier 210 and the battery module 220 and is connected. The third abutment 420 abuts against the carrier 210. For example, the fixing rod 410 is inserted into the second type through hole 212 of the carrier 210. The threaded hole 2211 also includes a second threaded hole 2211b. The fixing rod 410 can be threadedly connected to the second threaded hole 2211b on the end plate 221 of the battery module 220, thereby realizing the threaded connection relationship between the entire fixing member 400 and the battery module 220.

[0061] See Figure 9 In some embodiments, a recess 421 is provided on the third abutment 420. The recess 421 is disposed on the end face of the third abutment 420 for connecting the fixing rod 410. The recess 421 can be a circular groove, making the recess 421 a closed loop and surrounding the fixing rod 410. A sealing strip 430, such as an O-ring, is disposed in the recess 421. By providing the recess 421, the installation of the sealing strip 430 can be effectively limited, improving the installation efficiency and accuracy of the sealing strip 430. In its natural state without pressure, the thickness of the sealing strip 430 is greater than the depth of the groove 421, causing the sealing strip 430 to protrude relative to the end face of the third abutment 420. During the installation of the hanger 300, the sealing strip 430 will abut between the third abutment 420 and the carrier 210. This allows the sealing strip 430 to provide a good seal for the second type through hole 212 and also facilitates the adjustment of the abutment pressure between the third abutment 420 and the carrier 210.

[0062] See Figure 7In some embodiments, the position and number of the second type of through holes 212 correspond to the number of battery cells 222 that can be accommodated by the support position 211. For example, when there are two support positions 211 and two battery modules 220, the two support positions 211 can be referred to as the first support position 2111 and the second support position 2112, respectively, and the two battery modules 220 can be referred to as the first battery module 2201 and the second battery module 2202, respectively. The first battery module 2201 is located at the first support position 2111, and the second battery module 2202 is located at the second support position 2112. The first battery module 2201 can include two or four battery cells 222, while the second battery module 2202 can include four battery cells 222. Two mounting pieces 300 can be connected to the same battery module 220, that is, one mounting piece 300 is connected to each of the two end plates 221 of the battery module 220. Without the fastener 400, the second type of through hole 212 may include a third through hole 2123. There are two third through holes 2123 on the second bearing position 2112, while there can be four third through holes 2123 on the first bearing position 2111. The four third through holes 2123 on the first bearing position 2111 can be spaced apart along the arrangement direction of the battery cells 222 in the battery module 220.

[0063] See Figure 6 When the first battery module 2201 includes two battery cells 222, the distance between the two end plates 221 is relatively small, so that the two mounting pieces 300 can be threaded through the two closely spaced third through holes 2123; when the first battery module 2201 includes four battery cells 222, the distance between the two end plates 221 is relatively large, so that the two mounting pieces 300 can be threaded through the two widely spaced third through holes 2123. Therefore, by increasing the number of third through holes 2123 on the first bearing position 2111 to be greater than the number of hanging members 300—for example, by increasing the number of third through holes 2123 on the first bearing position 2111 to twice or more the number of hanging members 300—the hanging members 300 can be fixedly connected to the end plate 221 by passing through specific third through holes 2123 on the first bearing position 2111 when the number of battery cells 222 included in the first battery module 2201 changes. Since the number of battery cells 222 in the second battery module 2202 can remain unchanged, the number of third through holes 2123 on the second bearing position 2112 can be equal to the number of hanging members 300.

[0064] See Figure 7When a fixing member 400 is provided, the second type of through hole 212 may also include a fourth through hole 2124, which is spaced apart from the third through hole 2123, and the fixing member 400 passes through the fourth through hole 2124. Two fixing members 400 can be connected to the same battery module 220. Since the fixing member 400 passes through the fourth through hole 2124, the first battery module 2201 can include two or four battery cells 222, while the second battery module 2202 can include four battery cells 222. Similar to the above-mentioned mounting member 300 and third through hole 2123, the second bearing position 2112 has two fourth through holes 2124, while the first bearing position 2111 has four fourth through holes 2124. Therefore, when both the hanging member 300 and the fixing member 400 are provided, the number of second-type through holes 212 formed by the third through hole 2123 and the fourth through hole 2124 on the first bearing position 2111 can be eight, and the number of second-type through holes 2122 formed by the third through hole 2123 and the fourth through hole 2124 on the second bearing position 2112 can be four.

[0065] See Figure 7 In some embodiments, the fixing device 10 further includes a plug 500, which blocks the empty second-type through hole 212 on the bearing position 211. For example, for the aforementioned first bearing position 2111, since some of the third through holes 2123 do not have a hanging member 300 inserted, and some of the fourth through holes 2124 do not have a fixing member 400 inserted, in order to improve the sealing performance of the fixing device 10 and the energy storage device 20, the plug 500 can be inserted into the empty third through holes 2123 and fourth through holes 2124, so that the plug 500 blocks the third through holes 2123 and fourth through holes 2124.

[0066] In some embodiments, when there are three or more battery modules 220, all battery modules 220 are arranged in a straight line, that is, in a straight line extending along the Z-axis. Along the arrangement direction of the battery modules 220, the two battery modules 220 located at the very end are referred to as end battery modules, and the battery module 220 located between the two end battery modules is referred to as the middle battery module. The end battery modules have a hanging member 300 at the corner away from the middle battery module, and a fixing member 400 is provided at the corner of the end battery modules near the middle battery module. The middle battery module has fixing members 400 at all corners; that is, the middle battery module does not have hanging members 300, but only fixing members 400. The end battery modules have both hanging members 300 and fixing members 400. For example, when the battery module's plan view is roughly rectangular, the end battery module has mounting brackets 300 at the two right angles furthest from the middle battery module, while the end battery module has fixing brackets 400 at the two right angles closest to the middle battery module. Therefore, the number of mounting brackets 300 and fixing brackets 400 on the end battery module is equal. The middle battery module has fixing brackets 400 at all four right angles.

[0067] See Figure 7 In some embodiments, the energy storage mechanism 200 further includes a first reinforcing rib 231, which protrudes from the support member 210. The battery module 220 can abut against the support member 210, allowing the connecting rod 321 of the mounting member 300 to pass sequentially through the support member 210 and the reinforcing rib along a first installation direction, thereby fixing the connecting rod 321 to the battery module 220. By providing the first reinforcing rib 231, the structural strength of the support member 210 can be improved, preventing deformation of the support member 210 under external forces.

[0068] See Figure 3 In some embodiments, the energy storage mechanism 200 further includes a second reinforcing rib 232, which connects between two adjacent battery modules 220. The second reinforcing rib 232 has a bent portion 2321, which corresponds to the docking point of the two adjacent battery modules 220, so that the bent portion 2321 can cover the docking point of the two adjacent battery modules 220. There is a receiving space 2322 between the bent portion 2321 and the docking point, in which flexible circuit boards or wires can pass through, thereby facilitating the arrangement of flexible circuit boards or wires. At the same time, the setting of the second reinforcing rib 232 also helps to improve the structural strength of the entire energy storage mechanism 200.

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.

[0070] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. 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. Therefore, the protection scope of this patent application should be determined by the appended claims.
