[0001] The present application relates to the field of energy storage technology, and in particular to a module bracket, an energy storage device and an electrical equipment. Background Art

[0002] The module bracket can be used to position the battery cell. The module bracket can connect multiple battery cells into a whole, thereby improving the connection stability of the multiple battery cells.

[0003] At present, the adaptability of the module bracket and the connection between multiple battery cells is poor, and the stability of the module bracket connecting multiple battery cells is poor. Utility Model Content

[0004] The technical problem to be solved by the embodiments of the present application is to provide a module bracket, an energy storage device and an electrical equipment, aiming to solve the problem of poor connection stability between the module bracket and the battery cell.

[0005] In a first aspect, the present application provides a module bracket, the module bracket comprising a first surface and a second surface disposed opposite to each other, the module bracket being provided with a plurality of through holes penetrating the first surface and the second surface, the through holes being used to accommodate battery cells;

[0006] A glue injection port is provided on the first surface, the glue injection port is located between two adjacent through holes, and the glue injection port is communicated with the two adjacent through holes;

[0007] The inner wall of the through hole has a flow channel communicated with the glue injection port.

[0008] In the present embodiment, a through hole is used to extend the battery cell, and a glue injection port connected to the through hole is provided on the first surface. The setting of the glue injection port can facilitate the pouring of glue. The glue injection port can guide the glue to the flow channel on the inner wall of the through hole. The glue can bond the inner wall of the through hole and the outer wall of the battery cell, thereby improving the connection stability between the module bracket and the battery cell.

[0009] In combination with the first aspect, in a feasible implementation, the flow channel surrounds the through hole, and the glue can be distributed along the flow channel to the inner wall of the through hole in a relatively uniform manner, thereby improving the stability of the glue bonding the battery cell and the module bracket.

[0010] In combination with the first aspect, in a feasible implementation, the flow channel is spiral-shaped, and the flow channel can evenly distribute the glue to the inner wall of the through hole when draining the glue, thereby improving the stability of the module bracket and the battery cell.

[0011] In combination with the first aspect, in a feasible implementation, the inner wall of the through hole is recessed to form the flow channel. The recessed inner wall of the through hole forms the flow channel, which can facilitate the molding of the flow channel. The flow channel on the inner wall of the through hole can be directly molded by injection molding. The recessed inner wall of the through hole forms the flow channel, which is also conducive to the installation of the module bracket and the battery cell. When the battery cell is installed in the through hole, the flow channel will not interfere with the battery cell.

[0012] In combination with the first aspect, in a feasible implementation, at least two elastic members are protruding from the inner wall of the through hole, the elastic members are in a spiral structure, and adjacent elastic members are arranged at intervals to form the flow channel. At least two elastic members are protruding from the inner wall of the through hole, the elastic members can contact the outer wall of the battery cell, and the elastic members can play a buffering role to improve the safety performance of the battery cell.

[0013] In combination with the first aspect, in a feasible implementation, the cross-sectional shape of the elastic member is semicircular, the dimension of the elastic member protruding from the inner wall of the through hole is 0.5 mm-2.5 mm, and the spacing between two adjacent elastic members is 6 mm-20 mm. The cross-sectional shape of the elastic member is semicircular, which can facilitate the overflow of the glue flowing into the flow channel, and is conducive to the connection between the glue and the outer wall of the battery cell.

[0014] In combination with the first aspect, in a feasible implementation, a protrusion is provided on the first surface, and the protrusion forms the glue injection port. Since the protrusion protrudes from the first surface and the protrusion forms the glue injection port, when pouring glue into the pouring port, the glue is not easy to spill onto the first surface.

[0015] In combination with the first aspect, in a feasible implementation, the protrusion includes a first section, a second section, a third section and a fourth section, the first section, the second section, the third section and the fourth section surround the injection port, the first section and the third section are arranged at intervals, and the second section is connected between the first section and the third section. The fourth section is connected between the first section and the third section, and the second section and the fourth section are arranged at intervals. The second section is arc-shaped, and the second section is adapted to the arc shape of the inner wall of the through hole. The fourth section is arc-shaped, and the fourth section is adapted to the arc shape of the inner wall of the through hole. The first section, the second section, the third section and the fourth section surround the pouring port, and the structure of the protrusion is simple, which is conducive to the molding of the protrusion. The second section is adapted to the arc shape of the inner wall of the through hole, which facilitates the glue to flow from the injection port to the flow channel of the through hole. The fourth section is adapted to the arc shape of the inner wall of the through hole, which facilitates the glue to flow from the injection port to the flow channel of the through hole.

[0016] In combination with the first aspect, in a feasible implementation, there are multiple through holes, and the multiple through holes include a first receiving hole and a second receiving hole that are adjacently arranged, the protrusion surrounds the area between the first receiving hole and the second receiving hole, the second section is located on one side of the first receiving hole along the axial direction, and the second section is spaced from the inner wall of the first receiving hole on one side close to the second receiving hole, and the fourth section is located on one side of the second receiving hole along the axial direction, and the fourth section is spaced from the inner wall of the second receiving hole on one side close to the first receiving hole. The side of the second section facing the fourth section is spaced from the inner wall of the first receiving hole, and the side of the fourth section facing the second section is spaced from the inner wall of the second receiving hole, so that the glue injection port is connected to the through hole, and the second direction is perpendicular to the first direction.

[0017] In combination with the first aspect, in a feasible implementation, the area between the first receiving hole and the second receiving hole in the first surface is recessed toward the direction of the second surface to form a gap, and the gap is surrounded by the protrusion. The area between the first receiving hole and the second receiving hole in the first surface is recessed toward the direction of the second surface, which is more conducive to the glue flowing from the glue injection port to the through hole, and prevents the glue from overflowing the first surface.

[0018] In combination with the first aspect, in a feasible implementation, the flow channel is connected to the notch, which is conducive to the glue flowing directly from the glue injection port to the flow channel.

[0019] In combination with the first aspect, in a feasible implementation, a plurality of the through holes are arranged in an array.

[0020] The module bracket can fix multiple battery cells, connect the multiple battery cells into a whole, and improve the connection stability between the multiple battery cells and the module bracket.

[0021] In combination with the first aspect, in a feasible implementation, the module bracket is further provided with a plurality of hollow holes penetrating the first surface and the second surface and located outside the through hole, and adjacent hollow holes are separated by reinforcing ribs. The module bracket is provided with hollow holes, which can reduce the weight of the module bracket, and the reinforcing ribs can improve the structural strength of the module bracket.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] Since the energy people need is highly temporal and spatial, in order to rationally utilize energy and improve energy utilization, it is necessary to use a medium or device to store one form of energy in the same form or convert it into another form of energy, and then release it in a specific form of energy based on future application needs. At present, the main way to generate green electricity is to develop green energy such as photovoltaics and wind power to replace fossil energy. At present, the generation of green electricity generally relies on photovoltaics, wind power, water potential, etc., while wind energy and solar energy generally have strong intermittent and volatile problems, which will cause instability of the power grid, insufficient electricity during peak hours, too much electricity during low hours, and unstable voltage will also cause damage to electricity. Therefore, it may cause "wind and light abandonment" problems due to insufficient electricity demand or insufficient grid acceptance capacity. To solve these problems, energy storage must be relied on. That is, electrical energy is converted into other forms of energy by physical or chemical means and stored, and energy is converted into electrical energy and released when needed. In simple terms, energy storage is similar to a large "power bank". When photovoltaic and wind energy are sufficient, electrical energy is stored and the stored electricity is released when needed.

[0036] Taking electrochemical energy storage as an example, this solution provides an energy storage device, which is equipped with a chemical battery. The chemical elements in the chemical battery are mainly used as energy storage media. The charging and discharging process is accompanied by chemical reactions or changes in the energy storage medium. Simply put, the electricity generated by wind and solar energy is stored in the chemical battery. When the use of external electricity reaches its peak, the stored electricity is released for use, or transferred to places where electricity is scarce for use.

[0037] At present, energy storage (i.e. energy storage) has a wide range of application scenarios, including power generation side energy storage, grid side energy storage, renewable energy grid-connected energy storage and user side energy storage. The corresponding types of energy storage devices include:

[0038] (1) Large energy storage containers used in grid-side energy storage scenarios can serve as high-quality active and reactive power regulation power sources in the grid, achieve load matching of electric energy in time and space, enhance the ability to absorb renewable energy, and are of great significance in grid system backup, relieving peak load power supply pressure, and peak and frequency regulation;

[0039] (2) The main operating mode of small and medium-sized energy storage cabinets used in industrial and commercial energy storage scenarios (banks, shopping malls, etc.) on the user side and small household energy storage boxes used in home energy storage scenarios on the user side is "peak shaving and valley filling". Since there is a large price difference in electricity charges at peak and valley locations according to electricity demand, after users have energy storage equipment, in order to reduce costs, they usually charge the energy storage cabinets / boxes during the low electricity price period; during the peak electricity price period, the electricity in the energy storage equipment is discharged for use to achieve the purpose of saving electricity bills. In addition, in remote areas and areas prone to natural disasters such as earthquakes and hurricanes, the existence of household energy storage devices is equivalent to users providing themselves and the power grid with backup power, eliminating the inconvenience caused by frequent power outages due to disasters or other reasons.

[0040] The energy storage device has a battery cell. For a cylindrical battery cell, a module bracket is generally used for fixing. However, the current module bracket has poor fixing stability for the cylindrical battery cell.

[0041] The present application discloses an electric device, which includes an energy storage device. The electric device may be a power-consuming device such as a vehicle that has a power supply.

[0042] See also Figure 1 and Figure 2 , the present application discloses an energy storage device 1000. For ease of understanding, the first direction is defined as the Z-axis direction, the second direction is defined as the X-axis direction, and the third direction is defined as the Y-axis direction.

[0043] The energy storage device 1000 includes a module bracket 200 and a plurality of battery cells 100. The module bracket 200 includes a first surface 210 and a second surface 220 that are arranged opposite to each other. The module bracket 200 is provided with a plurality of through holes 230 that penetrate the first surface 210 and the second surface 220. The plurality of through holes 230 correspond one-to-one to the plurality of battery cells 100. Each battery cell 100 extends into the corresponding through hole 230. The outer wall of the battery cell 100 is connected to the inner wall of the through hole 230 by glue.

[0044] In the module bracket provided in the present application, the battery cell 100 is cylindrical, and the through hole 230 is substantially a cylindrical through hole 230 adapted to the shape of the battery cell 100 .

[0045] There may be two module supports 200, the through holes 230 of the two module supports 200 correspond one to one, the multiple battery cells 100 correspond one to one to the through holes 230 of one of the two module supports 200, and the multiple battery cells 100 also correspond one to one to the through holes 230 of the other of the two module supports 200. When installing the battery cells 100, one end of each battery cell 100 extends into a corresponding through hole 230 of one of the two module supports 200, and the other end of each battery cell 100 extends into another corresponding through hole 230 of the other of the two module supports 200.

[0046] A glue injection port 240 is provided on the first surface 210, and the glue injection port 240 is connected to the through hole 230. The glue injection port 240 is used to facilitate the injection of glue. The glue can flow from the glue injection port 240 to the inner wall of the through hole 230. The glue injection port is located between two adjacent through holes. The glue bonds the battery cell 100 and the module bracket 200 to improve the connection stability between the battery cell 100 and the module bracket 200.

[0047] In the examples provided in this application, see Figure 3 and Figure 4 The inner wall of the through hole 230 has a flow channel 231 connected to the glue injection port 240. The glue flows from the glue injection port 240 into the flow channel 231, and the glue in the flow channel 231 can be connected to the outer wall of the battery cell 100, thereby improving the connection stability between the module support 200 and the battery cell 100. The glue in the flow channel 231 can overflow from the flow channel 231 and then be distributed to the inner wall of the through hole 230, and the glue can bond the inner wall of the through hole 230 and the outer wall of the battery cell 100, thereby improving the connection stability between the module support 200 and the battery cell 100.

[0048] In the embodiment provided in the present application, the flow channel 231 surrounds the through hole 230 , and when the glue flows into the flow channel 231 , it can be distributed relatively evenly on the inner wall of the through hole 230 , thereby improving the stability of the glue bonding the battery cell 100 and the module bracket 200 .

[0049] The flow channel 231 is spiral-shaped and can guide the glue from a position close to the first surface 210 to a position close to the second surface 220 , so as to more evenly distribute the glue to the inner wall of the through hole 230 , thereby improving the stability of the module bracket 200 and the battery cell 100 .

[0050] In some embodiments, the inner wall of the through hole 230 is recessed to form the flow channel 231. The inner wall of the through hole 230 is recessed to form the flow channel 231, which can facilitate the molding of the flow channel 231. The flow channel 231 on the inner wall of the through hole 230 can be directly molded by injection molding. The inner wall of the through hole 230 is recessed to form the flow channel 231, which is also conducive to the installation of the module bracket 200 and the battery cell 100. When the battery cell 100 is installed in the through hole 230, the flow channel 231 will not interfere with the battery cell 100.

[0051] In some embodiments, at least two elastic members are protruding from the inner wall of the through hole 230, and adjacent elastic members are arranged at intervals to form the flow channel 231. Each elastic member is distributed on the inner wall of the through hole 230 in a spiral shape. The flow channel 231 formed by two adjacent elastic members can drain the glue and distribute the glue more evenly to the inner wall of the through hole 230. When the battery cell 100 is installed in the through hole 230, the elastic member can contact the outer wall of the battery cell 100, and the elastic member can play a buffering role, thereby improving the safety performance of the battery cell 100.

[0052] The cross-section of the elastic member is semicircular, the dimension of the elastic member protruding from the inner wall of the through hole 230 is 0.5mm-2.5mm, and the spacing between two adjacent elastic members is 6mm-20mm. The cross-section of the elastic member can be semicircular, which can facilitate the overflow of the glue flowing into the flow channel 231 and facilitate the connection between the glue and the outer wall of the battery cell.

[0053] In the module support 200 provided in the present application, a protrusion 250 is provided on the first surface 210, and the protrusion 250 surrounds the glue injection port 240. Since the protrusion 250 protrudes from the first surface 210 and the protrusion 250 surrounds the glue injection port 240, when glue is poured into the pouring port, the glue is not easy to spill onto the first surface 210.

[0054] Among them, see Figure 3 The enlarged view of the part A in the middle mold bracket, the protrusion 250 includes a first section 251, a second section 252, a third section 253 and a fourth section 254, the first section 251, the second section 252, the third section 253 and the fourth section 254 surround the injection port 240, the first section 251 and the third section 253 are arranged at intervals, the second section 252 is connected between the first section 251 and the third section 253, the second section 252 is arched toward the direction where the fourth section 254 is located, and the fourth section 254 is arched toward the direction where the second section 252 is located. The fourth section 254 is connected between the first section 251 and the third section 253, and the second section 252 and the fourth section 254 are arranged at intervals. The first section 251, the second section 252, the third section 253 and the fourth section 254 surround the pouring port, and the structure of the protrusion 250 is simple, which is conducive to the molding of the protrusion 250.

[0055] The first section 251 and the third section 253 are convexly disposed on the first surface 210, and one of the second section 252 and the fourth section 254 crosses the through hole 230. If the second section 252 crosses the through hole 230, the second section 252 is spaced apart from the inner wall of the through hole 230. When glue is injected into the glue injection port 240, the glue can flow into the flow channel 231 of the through hole 230 from the gap between the second section 252 and the inner wall of the through hole 230. If the fourth section 254 crosses the through hole 230, the fourth section 254 is spaced apart from the inner wall of the through hole 230. When glue is injected into the glue injection port 240, the glue can flow into the flow channel 231 of the through hole 230 from the gap between the fourth section 254 and the inner wall of the through hole 230.

[0056] In some embodiments, the plurality of through holes 230 include a first receiving hole 230a and a second receiving hole 230b that are adjacently arranged, the protrusion 250 surrounds the area between the first receiving hole 230a and the second receiving hole 230b, the projection of the second section 252 along the first direction is within the first receiving hole 230a, the projection of the fourth section 254 along the first direction is within the second receiving hole 230b, and the side of the second section 252 facing the fourth section 254 is spaced from the inner wall of the first receiving hole 230a, and the side of the fourth section 254 facing the second section 252 is spaced from the inner wall of the second receiving hole 230b, and the first receiving hole 230a and the second receiving hole 230b are spaced apart along the second direction, and the second direction is perpendicular to the first direction.

[0057] In the embodiment provided in the present application, the second section 252 is located on one side of the first receiving hole 230a along the axial direction, and the second section 252 is spaced apart from the inner wall of the first receiving hole 230a on one side close to the second receiving hole 230b. The fourth section 254 is located on one side of the second receiving hole 230b along the axial direction, and the fourth section 254 is spaced apart from the inner wall of the second receiving hole 230b on one side close to the first receiving hole 230a.

[0058] The second section 252 is spaced from the inner wall of the first receiving hole 230a close to the second receiving hole 230b, so as to achieve communication between the first receiving hole 230a and the injection port 240. The fourth section 254 is spaced from the inner wall of the second receiving hole 230b close to the first receiving hole 230a, so as to achieve communication between the first receiving hole 230a and the injection port 240.

[0059] Specifically, the second section 252 crosses the first receiving hole 230a, the fourth section 254 crosses the second receiving hole 230b, the side of the second section 252 facing the fourth section 254 is spaced from the inner wall of the first receiving hole 230a, and the side of the fourth section 254 facing the second section 252 is spaced from the inner wall of the second receiving hole 230b, so that the glue injection port 240 can be connected with the through hole 230. When glue is injected into the glue injection port 240, the glue can flow to the flow channel 231 of the first receiving hole 230a and also to the flow channel 231 of the second receiving hole 230b.

[0060] The second section 252 is arc-shaped and matches the arc shape of the inner wall of the first receiving hole 230 a . The fourth section 254 is arc-shaped and matches the arc shape of the inner wall of the second receiving hole 230 b .

[0061] The center position of the projection of the second section 252 in the first direction and the center position of the projection of the first receiving hole 230a in the first direction are both located on the side of the second section 252 away from the fourth section 254. The side of the second section 252 facing the fourth section 254 plays a guiding role, guiding the glue to flow into the channel of the first receiving hole 230a. The center position of the projection of the fourth section 254 in the first direction and the center position of the projection of the second receiving hole 230b in the first direction are both located on the side of the fourth section 254 away from the second section 252. The side of the fourth section 254 facing the second section 252 plays a guiding role, guiding the glue to flow into the channel of the first receiving hole 230a.

[0062] The second section 252 is adapted to the arc shape of the inner wall of the first receiving hole 230a, so that the glue can flow from the injection port 240 to the flow channel of the first receiving hole 230a. The fourth section 254 is adapted to the arc shape of the inner wall of the second receiving hole 230b, so that the glue can flow from the injection port 240 to the flow channel 231 of the second receiving hole 230b.

[0063] In some embodiments, see Figure 4 and Figure 5 , Figure 4 A top view of a module bracket provided in an embodiment of the present application. Figure 5 for Figure 4 In the cross-sectional view along line BB, the area between the first receiving hole 230a and the second receiving hole 230b in the first surface 210 is recessed toward the direction of the second surface 220 to form a notch 211. The first receiving hole 230a and the second receiving hole 230b may be connected through the notch 211.

[0064] The area between the first receiving hole 230a and the second receiving hole 230b in the first surface 210 is recessed toward the direction of the second surface 220 to form a notch 211, and the notch 211 is surrounded by the protrusion 250, which is more conducive to the glue flowing from the glue injection port 240 to the through hole 230, preventing the glue from overflowing from the first surface 210.

[0065] The flow channel 231 is connected to the notch 211 , which is conducive to the glue flowing directly from the glue injection port 240 to the flow channel 231 .

[0066] The plurality of through holes 230 are arranged in an array. The module support 200 can fix the plurality of battery cells 100 so that the plurality of battery cells 100 are connected as a whole, thereby improving the connection stability between the plurality of battery cells 100 and the module support 200 .

[0067] See also Figure 6 and Figure 7 The module support 200 is also provided with a plurality of hollow holes 260 penetrating the first surface 210 and the second surface 220 and located at the periphery of the through hole 230, and reinforcing ribs 270 are formed between adjacent hollow holes 260. The module support 200 is provided with the hollow holes 260, which can reduce the weight of the module support 200, and the reinforcing ribs 270 can improve the structural strength of the module support 200.

[0068] In the module bracket 200 provided in the present application, each through hole 230 is surrounded by a barrel-shaped structure, the inner wall of the barrel-shaped structure is also the inner wall of the through hole 230, and the inner wall of the hollow hole 260 located outside the through hole 230 can serve as the outer wall of the barrel-shaped structure.

[0069] In the module bracket 200 provided in the present application, a plurality of through holes 230 are arranged in an array. Specifically, the plurality of through holes 230 include a plurality of rows of through holes 230 arranged along the third direction, and each row of through holes 230 includes a plurality of through holes 230 arranged along the second direction. It can be understood that each through hole 230 is surrounded by a barrel-shaped structure. Taking the array formed by four barrel-shaped structures as an example, the four barrel-shaped structures are respectively a first barrel-shaped structure 200a, a second barrel-shaped structure 200b, a third barrel-shaped structure 200c and a fourth barrel-shaped structure 200d.
