[0041] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0042] In a first aspect, as Figure 1 and Figure 2 shown, an energy storage device 100 is provided in an embodiment of the present application. The energy storage device 100 includes an energy storage main body 1, a wall-mounted component 2, a connection component 3, a cover body 4, and a holding member 5. The energy storage main body 1 is used for storing electric energy; the wall-mounted component 2 is used for connecting with an external device 200. The connection component 3 is disposed on the energy storage main body 1 and is detachably connected to the wall-mounted component 2 to mount the energy storage component on the external device 200; the cover body 4 is used for covering the energy storage main body 1 to protect the energy storage main body 1; the holding member 5 is disposed on the energy storage main body 1 to facilitate the handling of the energy storage main body 1. The external device 200 can be a wall, a housing of a machine, or a machine frame, etc., as long as it can be fixedly connected to the wall-mounted component 2.
[0043] For the above-mentioned energy storage main body 1, as Figure 2 and Figure 3 shown, the energy storage main body 1 can be generally rectangular parallelepiped-shaped. The energy storage main body 1 can include a primary battery or a secondary battery, for example, it can include one or more of a lithium-ion battery, a lithium-ion polymer battery, a lithium iron phosphate battery, a lead-acid battery, and a nickel-cadmium battery.
[0044] For the above-mentioned wall-mounted component 2, as Figure 4As shown, the wall-mounted component 2 includes a wall-mounted part 21 and a connecting rod 22. The number of wall-mounted parts 21 is multiple, and multiple wall-mounted parts 21 are simultaneously connected to the connecting component 3, which can enhance the connection stability between the connecting component 3 and the wall-mounted component 2. The connecting rod 22 is connected to multiple wall-mounted parts 21, enabling multiple wall-mounted parts 21 to form an integral whole, facilitating the installation of multiple wall-mounted parts 21, and fixing the relative positions between multiple wall-mounted parts 21, improving the problem that the connecting component 3 cannot be normally connected to the wall-mounted component 2 due to errors in the relative positions between multiple wall-mounted parts 21. The wall-mounted part 21 can be rod-shaped, and the frame structure formed by connecting the connecting rod 22 and multiple wall-mounted parts 21 can not only achieve multi-point connection between the connecting component 3 and the wall-mounted component 2, but also reduce the material usage of the wall-mounted component 2 and lower the production cost of the wall-mounted component 2 compared with a plate-shaped wall-mounted component 2. In some other embodiments, the number of wall-mounted parts 21 is one, that is, the wall-mounted component 2 includes one wall-mounted part 21 and does not include a connecting rod 22. Optionally, the number of wall-mounted parts 21 is two.
[0045] The wall-mounted part 21 can be made of a metal material, such as aluminum, stainless steel, aluminum alloy, etc., to enhance the bearing capacity of the wall-mounted part 21; the connecting rod 22 can be made of a metal material or a plastic material. When both the connecting rod 22 and the wall-mounted part 21 are made of a metal material, the connecting rod 22 can be welded to the wall-mounted part 21.
[0046] For the above-mentioned wall-mounted part 21, in some embodiments, as Figure 4 shown, the wall-mounted part 21 extends along the first direction X as a whole. The wall-mounted part 21 includes a first wall 211, a second wall 212, a third wall 213, a fourth wall 214, a fifth wall 215, and a guiding wall 216, and the first wall 211, the second wall 212, the third wall 213, the fourth wall 214, the fifth wall 215, and the guiding wall 216 are directly or indirectly connected. In some embodiments, the first wall 211, the second wall 212, the third wall 213, the fourth wall 214, the fifth wall 215, and the guiding wall 216 are formed by punching and stamping a metal plate, which is beneficial to reducing the manufacturing cost of the wall-mounted part 21 and has a strong bearing capacity.
[0047] In some embodiments, as Figure 4 shown, the first wall 211 extends along the first direction X, and the first wall 211 can be in the shape of a rectangular thin sheet. The first wall 211 is detachably connected to the connecting component 3. Specifically, as Figure 2 and Figure 5 shown, the connecting component 3 includes a recess 3111 opened along the second direction Y, the second direction Y is perpendicular to the first direction X, the second direction Y is opposite to the direction of gravity, the first direction X is the horizontal direction, and a part of the first wall 211 is disposed in the recess 3111, so that the connecting component 3 is hung on the first wall 211.
[0048] It can be understood that this connection between the connecting component 3 and the wall-mounted component 2 is a weak connection. When the connecting component 3 is subjected to a thrust force along the first direction X and the connecting component 3 moves relative to the wall-mounted component 2 along the first direction X, the first wall 211 will leave the recess 3111, resulting in the disconnection of the connection between the connecting component 3 and the wall-mounted component 2, and further causing the energy storage main body 1 to fall and be damaged. In extreme natural environments, such as during an earthquake, the up-and-down vibration of the wall will also cause the energy storage main body 1 to fall and be damaged.
[0049] To improve the above problems, in some embodiments, as Figure 4 and Figure 5 shown, the wall-mounted component 2 further includes a first hole 2151, and the first hole 2151 is specifically provided on the fifth wall 215; the connecting component 3 further includes a second hole 3121, and the included angle between the extending direction of the first hole 2151 and the second hole 3121 and the second direction Y is greater than 0 degrees and less than 180 degrees, and the central axes of the first hole 2151 and the second hole 3121 coincide. Among them, the first hole 2151 and the second hole 3121 can be used for a first fastener to pass through. The first fastener can be a screw, a bolt, etc. When the first fastener passes through the first hole 2151 and the second hole 3121, it can prevent the connecting component 3 from moving relative to the wall-mounted component 2 along the first direction X, that is, prevent the first wall 211 from disengaging from the recess 3111, reduce the probability of disconnection between the connecting component 3 and the wall-mounted component 2, and improve the problem of the energy storage device 100 falling and being damaged. Among them, the included angle between the extending direction of the first hole 2151 and the second hole 3121 and the second direction Y is preferably 90 degrees.
[0050] It can be understood that, as Figure 4 shown, when the number of the wall-mounted parts 21 is multiple, the number of the first walls 211 is multiple. The multiple wall-mounted parts 21 can be arranged at intervals along the second direction Y, that is, the multiple first walls 211 are arranged at intervals along the second direction Y. Correspondingly, as Figure 5 shown, the number of the recesses 3111 can also be set to be multiple, and the multiple recesses 3111 are arranged at intervals along the second direction Y. Among them, as Figure 2 shown, each first wall 211 is partially arranged in at least one recess 3111, so along the second direction Y, the connecting component 3 and the wall-mounted component 2 are connected at multiple points, enhancing the anti-torsion performance of the connecting component 3 relative to the wall-mounted component 2 rotating around the first direction X, and improving the connection stability between the connecting component 3 and the wall-mounted component 2.
[0051] In some embodiments, the third wall 213 is used to connect with the external device 200. The third wall 213 can be connected to the external device 200 by welding, snap connection or screw connection. For screw connection, exemplarily, as Figure 4As shown, the third wall 213 is provided with a third hole 2131 for the second fastener to pass through. The second fastener can be a screw, a bolt, an expansion screw, etc. When the second fastener passes through the third hole 2131, it can be connected to the external device 200, thereby mounting the wall-mounted part 21 on the external device 200. It can be understood that the external device 200 is pre-provided with a blind hole, a through hole or a threaded hole for connection with the second fastener. Optionally, the number of the third holes 2131 is three to enhance the connection strength between the wall-mounted part 21 and the external device 200.
[0052] In some embodiments, as Figure 4 shown, the second wall 212 connects the first wall 211 and the third wall 213; along the third direction Z, the first wall 211 and the third wall 213 are spaced apart. The third direction Z is perpendicular to the first direction X and the second direction Y. It can be understood that the third direction Z is the direction in which the energy storage body 1 and the external device 200 are arranged. The first wall 211 is spaced from the external device 200, so that the first wall 211 can be disposed in the recess 3111, improving the problem that the external device 200 hinders the first wall 211 from being disposed in the recess 3111.
[0053] In some embodiments, as Figure 4 shown, the fourth wall 214 connects the third wall 213 and the fifth wall 215; along the third direction Z, the third wall 213 and the fifth wall 215 are spaced apart. It can be understood that along the third direction Z, the fifth wall 215 and the first wall 211 are on the same side of the third wall 213. The fifth wall 215 is spaced from the external device 200, so that the first fastener can pass through the first hole 2151 and can extend out of the first hole 2151 along the third direction Z, facilitating the first fastener to pass through the first hole 2151 and the second hole 3121. It can also shorten the distance between the fifth wall 215 and the connection assembly 3, improving the connection stability between the fifth wall 215 and the connection assembly 3. Further, the fifth wall 215 abuts against the connection assembly 3, the first hole 2151 communicates with the second hole 3121, and the first fastener can tightly press the fifth wall 215 against the connection assembly 3, improving the connection stability between the fifth wall 215 and the connection assembly 3.
[0054] In some embodiments, as Figure 4As shown, the guiding wall 216 is arranged on one side of the first wall 211 facing the second direction Y; the guiding wall 216 includes a first guiding surface 2161, and along the second direction Y, the first guiding surface 2161 is arranged in a form that gradually moves away from the recess 3111. When installing the connecting component 3 on the wall-mounted component 2, by making the first guiding surface 2161 contact the recess 3111, the connecting component 3 can be guided along the second direction Y, facilitating the alignment of the first hole 2151 and the second hole 3121, reducing the difficulty of installing the connecting component 3 on the wall-mounted component 2, and improving the installation efficiency. Optionally, the number of guiding walls 216 is two, and the two guiding walls 216 are arranged at intervals along the first direction X and are mirror-symmetrical along the first direction X, so that the connecting component 3 can be guided along the first direction X or the opposite direction of the first direction X, further reducing the difficulty of installing the connecting component 3 on the wall-mounted component 2 and improving the installation efficiency.
[0055] For the above-mentioned connecting component 3, as Figure 5 shown, the connecting component 3 includes a connecting piece 31. The number of connecting pieces 31 can be multiple. When multiple connecting pieces 31 are connected to the wall-mounted component 2 at the same time, the connection stability between the connecting component 3 and the wall-mounted component 2 can be enhanced; when multiple connecting pieces 31 are connected to the energy storage main body 1 at the same time, the connection stability between the connecting component 3 and the energy storage main body 1 can be enhanced. The connecting piece 31 can be rod-shaped, and the connecting rods 22 are arranged at intervals, which can not only achieve multi-point connection between the wall-mounted component 2 and the connecting component 3, but also reduce the material consumption of the connecting component 3 compared with the plate-shaped connecting component 3, and reduce the production cost of the connecting component 3. Optionally, the number of connecting pieces 31 is two.
[0056] For the above-mentioned connecting piece 31, in some embodiments, as Figure 5 shown, the connecting piece 31 extends integrally along the second direction Y. The connecting piece 31 includes a sixth wall 311, a seventh wall 312 and an eighth wall 313, and the sixth wall 311, the seventh wall 312 and the eighth wall 313 are directly or indirectly connected. In some embodiments, the sixth wall 311, the seventh wall 312 and the eighth wall 313 are formed by punching and stamping a metal plate, which is beneficial to reducing the manufacturing cost of the wall-mounted part 21 and has strong bearing capacity.
[0057] In some embodiments, as Figure 5 shown, the sixth wall 311 can be in the shape of a rectangular thin sheet, and the sixth wall 311 is perpendicular to the first direction X. The sixth wall 311 includes a recess 3111, that is, the connecting piece 31 is detachably connected to the first wall 211 through the sixth wall 311. Among them, the number of the sixth walls 311 is multiple, and the multiple sixth walls 311 can be arranged at intervals along the second direction Y to realize the arrangement of the above-mentioned multiple recesses 3111 at intervals along the second direction Y.
[0058] In some embodiments, as Figure 5As shown, a plurality of sixth walls 311 may also be arranged at intervals along the first direction X, that is, a plurality of recesses 3111 are arranged at intervals along the first direction X. Wherein, a part of the first wall 211 is arranged in the plurality of recesses 3111, then the first wall 211 is connected to the plurality of recesses 3111. Along the first direction X, the connecting component 3 is connected to the wall-mounted component 2 at multiple points, enhancing the anti-torsion performance of the connecting component 3 relative to the wall-mounted component 2 rotating around the second direction Y, and improving the stability of the connection between the connecting component 3 and the wall-mounted component 2.
[0059] Similarly, in some embodiments, such as Figure 5 As shown, a plurality of connecting members 31 are arranged at intervals along the first direction X, and the connecting member 31 includes a recess 3111, that is, a plurality of recesses 3111 are arranged at intervals along the first direction X. Wherein, a part of the first wall 211 is arranged in the plurality of recesses 3111, then the first wall 211 is connected to the plurality of recesses 3111. Along the first direction X, the connecting component 3 is connected to the wall-mounted component 2 at multiple points, enhancing the anti-torsion performance of the connecting component 3 relative to the wall-mounted component 2 rotating around the second direction Y, and improving the stability of the connection between the connecting component 3 and the wall-mounted component 2.
[0060] In some embodiments, such as Figure 5 As shown, the sixth wall 311 includes a second guiding surface 3112, and the second guiding surface 3112 is connected to the inner surface of the recess 3111; along the second direction Y, the second guiding surface 3112 is arranged in a form of gradually approaching the first wall 211. When installing the connecting component 3 on the wall-mounted component 2, by making the second guiding surface 3112 contact the first wall 211, the connecting component 3 can be guided along the third direction Z, facilitating the movement of the first wall 211 into the recess 3111, reducing the difficulty of installing the connecting component 3 on the wall-mounted component 2, and improving the installation efficiency. Optionally, the number of the second guiding surfaces 3112 is two, and along the third direction Z, the two second guiding surfaces 3112 are respectively located on opposite sides of the recess 3111, so that the first wall 211 can be guided along the third direction Z or the opposite direction of the third direction Z, further reducing the difficulty of installing the connecting component 3 on the wall-mounted component 2, and improving the installation efficiency.
[0061] In some embodiments, such as Figure 5 As shown, the eighth wall 313 is used to connect to the energy storage body 1. The eighth wall 313 can be connected to the energy storage body 1 by welding, snap connection or screw connection. For screw connection, exemplarily, such as Figure 3 and Figure 5As shown, the eighth wall 313 is provided with a fourth hole 3131, and the energy storage main body 1 is provided with a fifth hole 11. The fourth hole 3131 and the fifth hole 11 are for a third fastener to pass through. When the third fastener passes through the fourth hole 3131 and the fifth hole 11, the eighth wall 313 can be connected to the energy storage main body 1, so as to install the connecting member 31 on the energy storage main body 1. It can be understood that the fifth hole 11 can be a blind hole, a through hole or a threaded hole. Optionally, the number of the fourth holes 3131 is three, which enhances the connection strength between the connecting member 31 and the energy storage main body 1.
[0062] In some embodiments, as Figure 2 and Figure 5 shown, the second hole 3121 is specifically provided in the seventh wall 312. Along the direction parallel to the first direction X, the part of the seventh wall 312 where the second hole 3121 is provided extends beyond the energy storage main body 1, that is, the second hole 3121 is located on one side of the energy storage main body 1 along the first direction X; correspondingly, the first hole 2151 is also located on one side of the energy storage main body 1 along the first direction X, which is convenient for installing the first fastener.
[0063] In some embodiments, as Figure 2 and Figure 5 shown, along the direction parallel to the first direction X, the eighth wall 313 extends beyond the energy storage main body 1, and when observed along the first direction X, the projection of the eighth wall 313 at least partially coincides with the projection of the energy storage main body 1. The fourth hole 3131 can be provided in this overlapping part of the eighth wall 313. Correspondingly, the fifth hole 11 is provided on one side of the energy storage main body 1 along the first direction X, so that the eighth wall 313 is connected to one side of the energy storage main body 1 along the first direction X, such that the third fastener does not occupy the space between the energy storage main body 1 and the external device 200, which is beneficial to shortening the distance between the energy storage main body 1 and the external device 200. And since the third fastener is connected to one side of the energy storage main body 1 along the first direction X, it is convenient to adjust the third fastener without disassembling the energy storage main body 1, which is beneficial to improving the maintenance efficiency. In some embodiments, the distance between the energy storage main body 1 and the external device 200 is 25 mm.
[0064] In some embodiments, as Figure 5 shown, the seventh wall 312 is connected to the eighth wall 313, and the seventh wall 312 is connected to the sixth wall 311 between the energy storage main body 1 and the external device 200. Therefore, the sixth wall 311 can be hidden between the energy storage main body 1 and the external device 200, and the wall-mounted assembly 2 can also be correspondingly reduced and hidden between the energy storage main body 1 and the external device 200, which improves the problem that the wall-mounted assembly 2 and the connection assembly 3 are exposed and may cause scratches to the user, and at the same time increases the aesthetic degree.
[0065] For the above-mentioned cover 4, as Figure 6As shown, the cover 4 can be generally in the shape of a cuboid shell. The cover 4 is detachably arranged on the energy storage main body 1, which can protect the surface of the energy storage main body 1, and can also protect the exposed electrical interfaces and electrical components, thereby prolonging the service life of the energy storage device 100.
[0066] In some embodiments, as Figure 2 and Figure 5 shown, the number of the covers 4 is two. Along the first direction X, the two covers 4 are respectively detachably arranged on the opposite sides of the energy storage main body 1; when observed along the first direction X, the projection of the eighth wall 313 coincides with the projection of the cover 4. Thus, the cover 4 can block the exposed eighth wall 313, improving the problem of user scratching caused by the exposure of the eighth wall 313, and at the same time increasing the aesthetic appearance.
[0067] In some embodiments, as Figure 6 shown, the cover 4 is provided with a card slot 41, and the card slot 41 can be snap-connected with a fourth fastener. The fourth fastener can be a screw or a bolt installed on the energy storage main body 1 to detachably install the cover 4 on the energy storage main body 1. Optionally, the card slot 41 can be a partial structure of a gourd hole.
[0068] For the above-mentioned holding member 5, as Figure 2 and Figure 3 shown, the holding member 5 is arranged on one side of the energy storage main body 1 in the first direction X. When the cover 4 is installed on the energy storage main body 1, the cover 4 covers the holding member 5, that is, the holding member 5 is located between the cover 4 and the energy storage main body 1. Thus, the cover 4 can block the holding member 5, making the appearance of the energy storage device 100 more flat and unified, and increasing the aesthetic appearance. The number of the holding members 5 can be two, and the two holding members 5 are respectively arranged on the opposite sides of the energy storage main body 1 along the first direction X, which is convenient for carrying. Optionally, the holding member 5 is a handle.
[0069] In the energy storage device 100 according to the embodiment of the present application, the connection assembly 3 is movably connected to the first wall 211 of the wall-mounted assembly 2 through the concave portion 3111. The first hole 2151 of the wall-mounted assembly 2 and the second hole 3121 of the connection assembly 3 can be penetrated by a first fastener, thereby preventing the first wall 211 from detaching from the concave portion 3111, reducing the probability of the disconnection between the connection assembly 3 and the wall-mounted assembly 2, and improving the problem of the energy storage device 100 being damaged by falling. The wall-mounted assembly 2 and the connection assembly 3 are both assembled by a plurality of rod-shaped components, which is beneficial to reducing the production cost. The wall-mounted assembly 2 and the connection assembly 3 are connected at multiple points along the first direction X and the second direction Y, improving the connection stability between the connection assembly 3 and the wall-mounted assembly 2. The first guiding surface 2161 and the second guiding surface 3112 can reduce the difficulty of installing the connection assembly 3 on the wall-mounted assembly 2 and improve the installation efficiency. The wall-mounted assembly 2 and a part of the connection assembly 3 can be hidden between the energy storage main body 1 and the external device 200, and the cover 4 can block the holding member 5 and a part of the connection assembly 3, improving the problem of user scratching, and at the same time increasing the aesthetic appearance.
