Description

Technical Field

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

[0002] Against the backdrop of the rapid development of the new energy industry, energy storage batteries, as the core component of energy storage and supply, are widely used in electric vehicles, energy storage power stations, portable devices and other fields.

[0003] In related technologies, most energy storage batteries use solid plates as the load-bearing foundation. However, solid plates have relatively weak strength and bending resistance, and are prone to structural deformation due to excessive local stress during long-term use or transportation. To improve the strength and bending resistance of solid plates, the common approach is to increase their thickness, but this increases their weight. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a battery storage device with better load-bearing capacity and deformation resistance.

[0005] A battery storage device according to some embodiments of this application includes: a support assembly, the support assembly including a carrier plate and a honeycomb plate, the upper side of the carrier plate having a carrier groove, the honeycomb plate being disposed in the carrier groove and fixedly connected to the carrier plate; and a protective frame disposed on the support assembly, the protective frame forming a receiving cavity, the receiving cavity being located above the honeycomb plate, the honeycomb plate being used to support a battery placed in the receiving cavity.

[0006] The battery storage device according to the embodiments of this application has at least the following beneficial effects: In the battery storage device of this application, after the battery is placed in the receiving cavity of the protective frame, the battery is supported by a honeycomb panel. The protective frame serves to protect the battery and reduce the risk of battery damage. By using the honeycomb panel to support the battery placed within the protective frame, the weight of the battery can be evenly distributed to the supporting plate, significantly improving the load-bearing capacity and deformation resistance of the support component. The honeycomb panel is a biomimetic (simulating honeycomb structure) material, whose core feature is achieving "high strength performance" through a "lightweight structure." When the honeycomb panel bears the pressure of the battery, the pressure is transmitted to each hexagonal cell of the honeycomb panel. Each side of the regular hexagon is a "supporting edge," which can evenly distribute the pressure of the battery to multiple surrounding cells, reducing the risk of breakage due to excessive stress at a single point. This is equivalent to "using multiple small support points to jointly bear a large weight." Furthermore, the "hollow cells" of the honeycomb panel replace the "fully filled structure" of traditional solid panels, significantly reducing material usage while ensuring support strength (for example, the weight of a honeycomb panel of the same thickness is only a fraction of that of a solid panel), thus reducing both cost and overall load. Furthermore, the greater the thickness of the honeycomb panel, the higher its "moment of inertia" (a mechanical property; the greater the moment of inertia, the stronger the bending resistance). For example, a honeycomb panel with a thickness of mm has a much higher bending resistance than a solid panel of the same thickness. This is because the "hollow areas" of the honeycomb panel effectively lengthen the "force arm," making the panel more difficult to bend or break.

[0007] According to some embodiments of this application, the bearing groove penetrates the upper and lower side walls of the bearing plate, and the honeycomb holes on the honeycomb plate penetrate the upper and lower side walls of the honeycomb plate.

[0008] According to some embodiments of this application, the protective frame includes a frame body and a flange connected to the bottom of the frame body, the frame body enclosing the receiving cavity, and the flange overlapping and connected to the upper side of the support component.

[0009] According to some embodiments of this application, the flange extends outward from the frame body, the flange is provided with a first mounting hole, the support component is provided with a second mounting hole corresponding to the first mounting hole, and the protective frame further includes a first fastener passing through the first mounting hole and the second mounting hole.

[0010] According to some embodiments of this application, the protective frame is provided with heat dissipation holes communicating with the receiving cavity.

[0011] According to some embodiments of this application, the protective frame has an opening on its side; The battery storage device further includes a ventilation and heat dissipation assembly installed at the opening, the ventilation and heat dissipation assembly including an inner ventilation mesh covering the opening and an outer ventilation mesh disposed on the side of the inner ventilation mesh away from the receiving cavity.

[0012] According to some embodiments of this application, the aperture of the inner ventilation mesh is smaller than the aperture of the outer ventilation mesh.

[0013] According to some embodiments of this application, the ventilation and heat dissipation assembly further includes a fan disposed between the inner ventilation mesh and the outer ventilation mesh.

[0014] According to some embodiments of this application, the support assembly further includes a bracket that supports the load-bearing plate; The support plate has a downward-curved edge around its perimeter, the top of the bracket is in contact with the bottom surface of the support plate, and the side of the bracket is in contact with the inner surface of the downward-curved edge.

[0015] According to some embodiments of this application, the support assembly further includes a second fastener, the bearing plate is provided with a third mounting hole, the top of the bracket is provided with a fourth mounting hole corresponding to the third mounting hole, and the second fastener passes through the third mounting hole and the fourth mounting hole.

[0016] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] like Figure 1 As shown, a battery storage device provided in one embodiment of this application includes a support component 100 and a protective frame 200. The support component 100 is used to support the battery, and the protective frame 200 is used to surround the battery to protect it.

[0023] Combination Figure 2 and Figure 3The support assembly 100 includes a support plate 110 and a honeycomb plate 120. The upper side of the support plate 110 is provided with a support groove 111, and the honeycomb plate 120 is disposed in the support groove 111 and fixedly connected to the support plate 110.

[0024] Specifically, the support plate 110 is basically horizontally positioned, and its thickness direction is basically perpendicular to the horizontal plane. The support groove 111 is formed on the upper side of the support plate 110, meaning that the support groove 111 at least penetrates the upper side of the support plate 110. The honeycomb panel 120 is a plate-like structure with multiple honeycomb holes. The honeycomb holes of the honeycomb panel 120 penetrate both the upper and lower sides of the honeycomb panel 120, and the cross-section of the honeycomb holes is a regular hexagonal structure. The honeycomb panel 120 is disposed within the support groove 111 and fixedly connected to the support plate 110. The honeycomb panel 120 is basically horizontally positioned, and its thickness direction is basically perpendicular to the horizontal plane.

[0025] In some embodiments, the periphery of the honeycomb panel 120 is welded to the sidewall of the support groove 111; in other embodiments, the support groove 111 is provided with a support portion that supports the support plate 110, and the support portion and the support plate 110 can be fixed by welding or by means of bolts.

[0026] like Figure 2 As shown, the protective frame 200 is disposed on the support assembly 100, and the protective frame 200 surrounds to form a receiving cavity 201. The receiving cavity 201 is located above the honeycomb panel 120, and the honeycomb panel 120 is used to support the battery placed in the receiving cavity 201.

[0027] Specifically, the protective frame 200 has an opening at its bottom, and the side plates surrounding the protective frame 200 form a receiving cavity 201. The protective frame 200 is mounted on the support assembly 100, with its bottom opening facing the honeycomb panel 120. When the battery is placed in the receiving cavity 201, the battery is supported by the honeycomb panel 120. The protective frame 200 serves to protect the battery and reduce the risk of battery damage.

[0028] like Figure 2 As shown, the top of the protective frame 200 is provided with a pick-up and drop-out port 204, through which relevant personnel can place the battery into the receiving cavity 201, or remove the battery from the receiving cavity 201 through the pick-up and drop-out port 204.

[0029] The battery storage device also includes a cover 230, which is detachably positioned over the access port 204. Furthermore, the protective frame 200 has positioning grooves 205 at the edge of the access port 204, and the cover 230 is positioned within these grooves 205, facilitating its installation. Additionally, the cover 230 can be secured to the protective frame 200 using bolts or clips.

[0030] Understandably, the honeycomb panel 120 is a biomimetic (simulating honeycomb structure) material. Its core feature is achieving high strength performance through a lightweight structure. When the honeycomb panel 120 bears the pressure of a battery, the pressure is transmitted to each hexagonal cell of the honeycomb panel 120. Each side of the regular hexagon is a "supporting edge," which can evenly distribute the pressure of the battery to multiple surrounding cells, reducing the risk of breakage due to excessive stress at a single point. It is equivalent to "using multiple small support points to jointly bear a large weight." In addition, the "hollow cells" of the honeycomb panel 120 replace the "fully filled structure" of traditional solid panels. While ensuring support strength, it significantly reduces material usage (for example, the weight of the honeycomb panel 120 of the same thickness is only 1 / 3 to 1 / 5 of that of a solid panel), reducing both cost and overall load. Furthermore, the greater the thickness of the honeycomb panel 120, the higher the "moment of inertia" of the panel (a mechanical indicator; the greater the moment of inertia, the stronger the bending resistance). For example, a 20mm thick honeycomb panel 120 has a much higher bending resistance than a solid panel of the same thickness. This is because the "hollow area" of the honeycomb panel 120 is equivalent to lengthening the "force arm", making the panel more difficult to be bent or broken.

[0031] In the battery storage device of this application, the battery placed in the protective frame 200 is supported by the honeycomb plate 120, which can evenly distribute the weight of the battery to the support plate 110, and greatly improve the load-bearing capacity and deformation resistance of the support component 100.

[0032] Combination Figure 2 and Figure 4 In some embodiments, the support groove 111 penetrates the upper and lower side walls of the support plate 110, and the honeycomb holes on the honeycomb plate 120 penetrate the upper and lower side walls of the honeycomb plate 120.

[0033] It is understood that the support groove 111 is a through groove, with its upper end penetrating the upper surface of the support plate 110 and being positioned opposite the receiving cavity 201, and its lower end penetrating the lower surface of the support plate 110. The honeycomb plate 120 is disposed within the support groove 111, with the upper ends of the honeycomb holes of the honeycomb plate 120 penetrating the upper surface of the honeycomb plate 120 and communicating with the receiving cavity 201, and the lower ends of the honeycomb holes of the honeycomb plate 120 penetrating the lower surface of the honeycomb plate 120 and communicating with the external environment. In this way, the honeycomb holes can connect the receiving cavity 201 with the external environment, playing a role in heat dissipation and ventilation. The heat generated by the battery operation can be discharged to the external environment through the honeycomb holes, which helps the battery dissipate heat.

[0034] It should be noted that the honeycomb panel 120 has multiple honeycomb holes. Some of the honeycomb holes can connect the receiving cavity 201 to the external environment, or all of the honeycomb holes can connect the receiving cavity 201 to the external environment.

[0035] Combination Figure 2 and Figure 3 In some embodiments, the protective frame 200 includes a frame body 210 and a flange 220 connected to the bottom of the frame body 210. The frame body 210 surrounds a receiving cavity 201, and the flange 220 is stacked and connected to the upper side of the support assembly 100.

[0036] It is understood that the side plates around the frame body 210 form a receiving cavity 201, and the flange 220 is connected to the bottom of the frame body 210. The flange 220 extends basically in the horizontal direction. The flange 220 can be stacked with the upper side wall of the bearing plate 110 or the honeycomb plate 120 to increase the contact area between the protective frame 200 and the support component 100, improve the strength of the connection between the protective frame 200 and the support component 100, and thus ensure reliability.

[0037] Specifically, the flange 220 is provided with a first mounting hole, the support component 100 is provided with a second mounting hole 112 corresponding to the first mounting hole, and the protective frame 200 also includes a first fastener 240 passing through the first mounting hole and the second mounting hole 112.

[0038] In some embodiments, the first fastener 240 may be a bolt, and one of the first mounting hole and the second mounting hole 112 is a through hole and the other is a threaded hole; in other embodiments, both the first mounting hole and the second mounting hole 112 are through holes, and the first fastener 240 includes a bolt and a nut adapted to the bolt; in still other embodiments, the first mounting hole and the second mounting hole 112 are pin holes, and the first fastener 240 is a pin.

[0039] Combination Figure 2 and Figure 3In some embodiments, the flange 220 extends outward toward the frame body 210 and protrudes from the receiving cavity 201, thus facilitating the connection operation between the flange 220 and the support assembly 100 by personnel. In other embodiments, the flange 220 may also extend inward toward the frame body 210.

[0040] like Figure 2 As shown, in some embodiments, the protective frame 200 is provided with heat dissipation holes 202 communicating with the receiving cavity 201. The heat dissipation holes 202 can connect the receiving cavity 201 with the external environment, playing a role in heat dissipation and ventilation. The heat generated by the battery operation can be discharged to the external environment through the heat dissipation holes 202, which helps the battery dissipate heat.

[0041] It is understood that at least one side plate of the protective frame 200 is provided with heat dissipation holes 202, and there are multiple heat dissipation holes 202. The shape of the heat dissipation holes 202 may be, but is not limited to, round holes, waist-shaped holes, polygonal holes, etc.

[0042] Combination Figure 2 and Figure 4 In some embodiments, the protective frame 200 has an opening 203 on its side; the battery storage device also includes a ventilation and heat dissipation assembly 300 installed at the opening 203, the ventilation and heat dissipation assembly 300 including an inner ventilation mesh 310 covering the opening 203 and an outer ventilation mesh 320 disposed on the side of the inner ventilation mesh 310 away from the receiving cavity 201.

[0043] Understandably, the inner ventilation mesh 310 and the outer ventilation mesh 320 provide ventilation to dissipate heat from the battery within the housing cavity 201. Simultaneously, they also serve a dustproof function, preventing external dust and debris from entering the housing cavity 201 and reducing the risk of battery contamination or damage. Furthermore, this application employs a double-layer ventilation mesh design with inner and outer ventilation mesh 310, which offers better dustproofing compared to a single-layer design.

[0044] Furthermore, the mesh size of the inner ventilation mesh 310 is smaller than that of the outer ventilation mesh 320. It is understandable that while the outer ventilation mesh 320 provides initial dust prevention, the inner ventilation mesh 310 can further enhance dust prevention by making its mesh size smaller than that of the outer ventilation mesh 320, thus blocking smaller dust particles outside the receiving cavity 201, resulting in a better dust prevention effect.

[0045] It should be noted that the ventilation and heat dissipation assembly 300 also includes a connecting outer frame 330. The inner ventilation mesh 310 and the outer ventilation mesh 320 are respectively disposed on both sides of the outer frame 330. The outer frame 330 is disposed on the protective frame 200 and located outside the opening 203. The outer frame 330 is used to provide installation positions for the inner ventilation mesh 310 and the outer ventilation mesh 320.

[0046] In some embodiments, the ventilation and heat dissipation assembly 300 further includes a fan (not shown) disposed between the inner ventilation mesh 310 and the outer ventilation mesh 320. The fan can extract heat from the receiving cavity 201, thereby further improving the heat dissipation effect. The heat dissipation hole 202 can be used as an air inlet. When the fan is started, ambient air can enter the receiving cavity 201 through the inlet air and then be discharged through the inner ventilation mesh 310 and the outer ventilation mesh 320.

[0047] Specifically, the fan is installed inside the outer frame 330 and located between the inner ventilation net 310 and the outer ventilation net 320.

[0048] Combination Figure 1 and Figure 5 In some embodiments, the support assembly 100 further includes a bracket 130, which is supported on the carrier plate 110. The bracket 130 is detachably connected to the carrier plate 110, so that the bracket 130 can be disassembled or its specifications replaced according to the specific usage scenario to adapt to the placement requirements in different scenarios.

[0049] Combination Figure 5 and Figure 6 Furthermore, the support plate 110 has downward-curved edges 113 around its perimeter. Specifically, the support plate 110 is bent downwards around its perimeter to form downward-curved edges 113. The top of the bracket 130 is in contact with the bottom surface of the support plate 110, and the side of the bracket 130 is in contact with the inner surface of the downward-curved edges 113. In this way, the bracket 130 can be positioned by means of the bottom surface of the support plate 110 and the inner surface of the downward-curved edges 113, which facilitates the assembly of the bracket 130 and improves the positioning accuracy of the bracket 130.

[0050] Furthermore, the support assembly 100 also includes a second fastener 131, the carrier plate 110 is provided with a third mounting hole 114, the top of the bracket 130 is provided with a fourth mounting hole corresponding to the third mounting hole 114, and the second fastener 131 passes through the third mounting hole 114 and the fourth mounting hole.

[0051] In some embodiments, the second fastener 131 may be a bolt, and one of the third mounting hole 114 and the fourth mounting hole is a through hole and the other is a threaded hole; in other embodiments, both the third mounting hole 114 and the fourth mounting hole are through holes, and the second fastener 131 includes a bolt and a nut adapted to the bolt; in still other embodiments, the third mounting hole 114 and the fourth mounting hole are pin holes, and the second fastener 131 is a pin.

[0052] In the battery storage device of this application, after the battery is placed in the receiving cavity 201 of the protective frame 200, the battery is supported by the honeycomb panel 120. The protective frame 200 serves to protect the battery and reduce the risk of battery damage. By using the honeycomb panel 120 to support the battery placed in the protective frame 200, the weight of the battery can be evenly distributed to the support plate 110, significantly improving the load-bearing capacity and deformation resistance of the support assembly 100. In addition, the honeycomb holes of the honeycomb panel 120 can connect the receiving cavity 201 with the external environment, playing a role in heat dissipation and ventilation. The heat generated by the battery operation can be discharged to the external environment through the honeycomb holes, which helps the battery dissipate heat. In addition, the heat dissipation holes 202, the inner ventilation mesh 310, and the outer ventilation mesh 320 can provide ventilation to dissipate heat from the battery in the receiving cavity 201. At the same time, the inner ventilation mesh 310 and the outer ventilation mesh 320 can also play a role in dust prevention, blocking external dust and debris from entering the receiving cavity 201 and reducing the risk of battery contamination or damage.
