Technical Field

[0001] This invention relates to the field of outdoor energy storage technology, and in particular to a power supply module and an outdoor energy storage device. Background Technology

[0002] With the development of energy storage technology, outdoor energy storage devices have emerged. These devices can power high-power appliances, providing a stable power supply for people outdoors and in emergencies, thus attracting widespread attention and favor. However, traditional outdoor energy storage devices have complex structures, low safety factors, and limited functions. To meet people's needs, new outdoor energy storage devices offer diverse functions, including communication and audio playback, while maintaining a simple structure for easy storage. However, this functional diversification necessitates that outdoor energy storage devices store sufficient electrical energy and provide suitable voltage, and they also require frequent movement during use, necessitating protection and securing of the battery modules. In traditional technologies, the battery module casing is generally matched to the size of the battery module, requiring high processing and assembly precision, and the installation process is complex, resulting in limited battery module selection and inconvenience for installers. Summary of the Invention

[0003] Therefore, it is necessary to provide a power supply module and an outdoor energy storage device.

[0004] A power supply module, comprising:

[0005] The first protective shell includes a vertically spliced ​​first width side plate and a bottom plate;

[0006] The second protective shell includes a top plate, a second width side plate, a first length side plate, and a second length side plate. The top plate and the second width side plate are perpendicularly joined, and the first length side plate and the second length side plate are perpendicularly joined on both sides of the top plate along its length. The top plate and the bottom plate are positioned opposite each other, and the second width side plate and the first width side plate are positioned opposite each other. The length of the bottom plate is greater than the length of the top plate, so that the first and second protective shells can be joined to form an adjustable-length accommodating space.

[0007] A battery module, wherein the battery module is installed within the accommodating space.

[0008] With this configuration, the first and second protective shells can be combined to form an adjustable-length accommodating space, which can accommodate and fix battery modules of different models and capacities, improving the practicality of outdoor energy storage devices. At the same time, the assembly of the first and second protective shells is simple and easy for assemblers to install.

[0009] In one embodiment, the first protective shell further includes a first connecting plate, which is connected to the side of the first width side plate that is relatively far from the bottom plate, and the extending direction of the first connecting plate is the same as the extending direction of the first width side plate.

[0010] The second protective shell also includes a second connecting plate, which is connected to the top plate on the side relatively away from the second width side plate. The second connecting plate extends in the direction away from the bottom plate and is perpendicular to the top plate.

[0011] Both the first connecting plate and the second connecting plate have connecting holes, which are used to connect the first connecting plate and the second connecting plate.

[0012] With this configuration, the first connecting plate is on the first protective shell, and the second connecting plate is on the second protective shell. The first connecting plate and the second connecting plate are provided with connecting holes for connection, which facilitates the connection of the first protective shell and the second protective shell, and makes it easy to adjust the accommodating space when the first protective shell and the second protective shell are connected.

[0013] In one embodiment, the first connecting plate is integrally formed with the first width side plate.

[0014] With this configuration, the first connecting plate and the first width side plate are integrally formed, which simplifies the production process, increases the connection strength, reduces production costs, and improves production efficiency.

[0015] In one embodiment, the second connecting plate is integrally formed with the top plate.

[0016] With this configuration, the second connecting plate and the top plate are integrally formed, which simplifies the production process, increases the connection strength, reduces production costs, and improves production efficiency.

[0017] In one embodiment, the bottom plate is provided with a guide tooth of a preset length on the side of the first width side plate, and the second width side plate is provided with a guide hole on the side of the top plate. The guide tooth can be inserted into the guide hole and can move in the guide hole.

[0018] With this design, the guide teeth of the preset length can cooperate with the guide holes, allowing the guide teeth to be inserted into the guide holes and move within them for installation guidance. This facilitates the installation of the first and second protective shells and also allows for adjustment of the accommodating space to accommodate battery modules of various sizes, thus improving the usability of the outdoor energy storage device.

[0019] In one embodiment, the first length side plate and / or the second length side plate are further provided with a clearance groove, which is used to make way for the socket circuit board.

[0020] This design, with its clearance groove, is intended to make way for the socket circuit board, making the circuit board easy to install and facilitating circuit connection.

[0021] In one embodiment, the bottom plate is further provided with stop portions on both sides along its length, and the protrusion direction of the stop portions is towards the top plate.

[0022] With this configuration, stop sections are also provided on both sides of the base plate along its length, with the protrusions of the stop sections facing the top plate. This prevents the second protective shell from moving and detaching along the width of the base plate during movement, thereby preventing the battery module from leaving the housing space, enhancing installation stability, and improving the safety of the power supply module.

[0023] In one embodiment, the base plate and the first width side plate are integrally formed.

[0024] This design allows the base plate and the first width side plate to be integrally formed, simplifying the production process, increasing connection strength, reducing production costs, and improving production efficiency. At the same time, it simplifies the installation process and saves manpower and resources.

[0025] In one embodiment, the top plate, the second width side plate, the first length side plate, and the second length side plate are integrally formed.

[0026] This design allows the top plate, the second width side plate, the first length side plate, and the second length side plate to be integrally formed, simplifying the production process, increasing connection strength, reducing production costs, and improving production efficiency. At the same time, it simplifies the installation process and saves manpower and resources.

[0027] In one embodiment, the two opposite sides of the second width side plate have a first gap and a second gap with the first length side plate and the second length side plate, respectively. One of the first gap and the second gap is used to expose the total negative electrode of the battery module, and the other is used to expose the total positive electrode of the battery module.

[0028] With this configuration, the first and second gaps are used to expose the total negative and total positive terminals of the battery module, which facilitates the installation of the battery module and also facilitates the connection between the battery module and the control board.

[0029] In one embodiment, the battery module further includes an insulating component and a power supply unit, wherein the insulating component is disposed between the power supply unit and the first protective shell and the second protective shell.

[0030] With this configuration, the insulating component is placed between the power supply unit and the first and second protective shells, thus insulating the battery module from the first and second protective shells and increasing the safety of the power supply module.

[0031] In one embodiment, the insulating element has multiple heat dissipation holes.

[0032] With this design, the insulation components have multiple heat dissipation holes. Since the battery temperature rises during the use of the power supply module, which can easily cause safety issues, the heat dissipation holes allow the heat generated by the battery to dissipate in a timely manner, thus improving the safety of the power supply module.

[0033] The present invention also provides an outdoor energy storage device, which includes the power supply module described above.

[0034] This design allows the outdoor energy storage device to accommodate battery modules of different sizes, and the power supply module is easy to install and securely installed, which is conducive to storing sufficient electricity, making the device more versatile and improving its safety and practicality.

[0058] Based on this, see Figure 1 , Figure 1 The diagram shows an overall structural schematic of an outdoor energy storage device 100 according to an embodiment of the present invention. This outdoor energy storage device 100 is commonly used in the field of outdoor family travel, and can also be applied to many other fields such as offices, enterprises, film crews, photography, fire fighting, medical care, disaster relief, RVs, yachts, communications, exploration, and construction.

[0059] The outdoor energy storage device 100 includes a lower shell 20, a panel frame 30, and a cover 40. The panel frame 30, the lower shell 20, and the cover 40 enclose an energy storage space for storing battery modules and other modules. The device is safe and reliable under impact, thus protecting the internal modules.

[0060] It is understandable that the panel frame 30, the lower shell 20 and the cover 40 can be integral or separate parts, as long as they can achieve the purpose of storing and protecting the internal modules of the outdoor energy storage device 100, and no limitation is made here.

In other embodiments, the panel frame 30, the lower shell 20 and the cover 40 can be enclosed to form other shapes, as long as they can achieve the purpose of storing and protecting the internal modules of the outdoor energy storage device 100, and are not limited here.

[0062] It is understood that the panel frame 30, the lower shell 20 and the cover 40 can be made of metal, plastic or other materials, as long as they can achieve the purpose of storing and protecting the internal modules of the outdoor energy storage device 100, and there are no restrictions here.

[0063] With the development of energy storage technology, outdoor energy storage devices 100 have emerged. These devices can drive high-power electrical appliances, providing a stable power supply for people outdoors and in emergencies, thus attracting widespread attention and favor. However, traditional outdoor energy storage devices 100 have complex structures, low safety factors, and limited functionality. To meet people's needs, new outdoor energy storage devices 100 offer diverse functions, including communication and audio playback, while maintaining a simple and easy-to-store structure. However, this functional diversification necessitates that the outdoor energy storage device 100 store sufficient electrical energy and provide suitable voltage, and it also requires frequent movement during use. Therefore, the battery module 13 needs protection and fixation. In traditional technology, the casing of the battery module 13 is generally matched to the size of the battery module 13, requiring high processing and assembly precision, and the installation steps are complex, resulting in limited battery module selection and inconvenience for installers.

[0064] Based on this, please refer to Figures 2 to 5 The power supply module 10 includes a first protective shell 11, which includes a first width side plate 111 and a bottom plate 112 that are vertically spliced ​​together.

[0065] The second protective shell 12 includes a top plate 121, a second width side plate 122, a first length side plate 123, and a second length side plate 124. The top plate 121 and the second width side plate 122 are perpendicularly joined, and the first length side plate 123 and the second length side plate 124 are perpendicularly joined on both sides of the top plate 121 along its length. The top plate 121 is opposite to the bottom plate 112, and the second width side plate 122 is opposite to the first width side plate 111. The length of the bottom plate 112 is greater than the length of the top plate 121, so that the first protective shell 11 and the second protective shell 12 can be joined to form an adjustable length accommodating space.

[0067] With this configuration, the first protective shell 11 and the second protective shell 12 can be combined to form an adjustable length accommodating space, which can accommodate and fix battery modules 13 of different models and capacities, improving the practicality of the outdoor energy storage device 100. At the same time, the assembly operation of the first protective shell 11 and the second protective shell 12 is simple and convenient for assemblers to install.

[0068] It is understandable that the accommodating space formed by the combination of the first protective shell 11 and the second protective shell 12 is adapted to the internal space of the energy storage device.

[0069] Please refer to it again. Figure 2 , Figure 4 and Figure 5In one embodiment, the first protective shell 11 further includes a first connecting plate 113, which is connected to the side of the first width side plate 111 that is relatively away from the bottom plate 112, and the extending direction of the first connecting plate 113 is the same as the extending direction of the first width side plate 111.

Both the first connecting plate 113 and the second connecting plate 125 are provided with connecting holes 14, as long as the effect of connecting and fixing the first protective shell 11 and the second protective shell 12 can be achieved.

[0075] With this configuration, the first connecting plate 113 and the first width side plate 111 are integrally formed, which simplifies the production process, increases the connection strength, reduces production costs, and improves production efficiency.

[0076] It is understood that in other embodiments, the forming method of the first connecting plate 113 and the first width side plate 111 is not limited, as long as the purpose of connection and fixation can be achieved.

[0077] In one embodiment, the second connecting plate 125 is integrally formed with the top plate 121.

[0078] With this configuration, the second connecting plate 125 and the top plate 121 are integrally formed, which simplifies the production process, increases the connection strength, reduces production costs, and improves production efficiency.

[0079] It is understood that in other embodiments, the forming method of the second connecting plate 125 and the top plate 121 is not limited, as long as the purpose of connection and fixation can be achieved.

[0080] Please refer to it again. Figure 2 , Figure 4 and Figure 5 In one embodiment, the bottom plate 112 is provided with a guide tooth 1121 of a preset length on the side of the first width side plate 111 that is far away from the first width side plate 111, and the second width side plate 122 is provided with a guide hole 1221 on the side of the top plate 121 that is far away from the top plate 121. The guide tooth 1121 can be inserted into the guide hole 1221 and can move in the guide hole 1221.

[0081] With this configuration, the guide teeth 1121 of the preset length can cooperate with the guide holes 1221, allowing the guide teeth 1121 to be inserted into the guide holes 1221 and to move within the guide holes 1221 for installation guidance. This facilitates the installation of the first protective shell 11 and the second protective shell 12, while also allowing for adjustment of the size of the accommodating space to accommodate various battery modules of different volumes, thus improving the usability of the outdoor energy storage device 100.

[0082] It is understood that the shape of the guide tooth 1121 can be square, round or other shapes, as long as it can achieve the purpose of installation guidance, and there is no limitation here.

[0086] This design of the clearance groove 15 is intended to make way for the socket circuit board 50, making the socket circuit board 50 easy to install and convenient for circuit connection.

[0087] Understandably, the position and shape of the clearance groove 15 are adapted to the socket circuit board 50 to facilitate the installation of the socket circuit board 50.

[0088] It can be further understood that the clearance groove 15 can be a through hole or a recess, as long as it can provide clearance space for the installation of the socket circuit board 50.

[0089] Please refer to it again. Figure 2 and Figure 4 In one embodiment, the bottom plate 112 is provided with stop portions 1122 protruding on both sides along its length, and the protruding direction of the stop portions 1122 is towards the top plate 121.

[0090] With this configuration, stop portions 1122 are also provided on both sides of the base plate 112 along its length. The protruding direction of the stop portions 1122 is towards the top plate 121, which prevents the second protective shell 12 from moving along the width direction of the base plate 112 during movement, thereby preventing the battery module 13 from leaving the accommodating space, enhancing the installation stability, and improving the safety of the power supply module 10.

[0091] It is understood that the stop part 1122 can be a single structure or composed of multiple structures, as long as it can achieve the purpose of stopping the second protective shell 12 to detach in the width direction, and there is no limitation here.

[0092] It is understood that the shape of the stop part 1122 can be rectangular, triangular or other shapes, as long as it can achieve the purpose of stopping the second protective shell 12 to separate in the width direction, and there is no limitation here.

[0094] In one embodiment, the base plate 112 and the first width side plate 111 are integrally formed.

[0095] With this configuration, the base plate 112 and the first width side plate 111 are integrally formed, which simplifies the production process, increases the connection strength, reduces production costs, improves production efficiency, simplifies the installation process, and saves manpower and resources.

[0096] It is understood that in other embodiments, the forming method of the base plate 112 and the first width side plate 111 is not limited, as long as the purpose of connection and fixation can be achieved.

[0097] In one embodiment, the top plate 121, the second width side plate 122, the first length side plate 123, and the second length side plate 124 are integrally formed.

[0098] With this configuration, the top plate 121, the second width side plate 122, the first length side plate 123, and the second length side plate 124 are integrally formed, which simplifies the production process, increases the connection strength, reduces production costs, and improves production efficiency. At the same time, it simplifies the installation process and saves manpower and resources.

[0099] It is understood that in other embodiments, the forming methods of the top plate 121, the second width side plate 122, the first length side plate 123 and the second length side plate 124 are not limited, as long as the purpose of connection and fixation can be achieved.

[0100] Please refer to it again. Figure 2 and Figure 5 In one embodiment, the two opposite sides of the second width side plate 122 have a first gap 1222 and a second gap 1223 with the first length side plate 123 and the second length side plate 124, respectively. One of the first gap 1222 and the second gap 1223 is used to expose the total negative electrode of the battery module 13, and the other is used to expose the total positive electrode of the battery module 13.

[0101] With this configuration, the first gap 1222 and the second gap 1223 are used to expose the total negative terminal and the total positive terminal of the battery module 13, which facilitates the installation of the battery module 13 and also facilitates the connection between the battery module 13 and the electronic control board.

[0102] It is understandable that the first gap 1222 and the second gap 1223 can be the same or different, as long as they can expose the total negative and total positive terminals of the battery module 13 for easy connection with the electronic control board. No limitation is made here.

[0103] It is understandable that the shape and size of the first gap 1222 and the second gap 1223 are not limited as long as they can expose the total negative and total positive terminals of the battery module 13 for easy connection with the electronic control board.

[0104] It is understood that in other embodiments, the first gap 1222 and the second gap 1223 may be located at other positions on the second width side plate 122, as long as they can expose the total negative and total positive terminals of the battery module 13 for easy connection with the electronic control board, and are not limited here.

[0106] With this configuration, the insulating component 134 is placed between the battery module 13 and the first protective shell 11 and the second protective shell 12, thereby insulating the battery module 13 from the first protective shell 11 and the second protective shell 12 and increasing the safety of the power supply module 10.

[0145] Please see Figure 15 In one embodiment, the conductive sheet has a plurality of soldering positions 1331, each soldering position 1331 corresponding to a positive electrode 131111 or a negative electrode 131112 of a battery cell 13111. The soldering position 1331 is provided with an H-shaped soldering hole 13311, which enables the conductive sheet to form two relatively bendable contact pieces 13312 at each soldering position 1331.

[0146] With this configuration, the welding position 1331 has an H-shaped welding hole 13311, so that the conductive sheet forms two relatively bendable contact pieces 13312 at each welding position 1331. During welding, the contact pieces 13312 can be bent, which is beneficial for the contact pieces 13312 to fully contact the positive electrode 131111 or negative electrode 131112 of the battery core 13111. This increases the contact area between the conductive sheet and the positive and negative electrodes 131112 of the battery core 13111, ensuring the conduction of electrode charge.

[0160] It is understandable that, in order to make the connection between the first frame 1321 and the second frame 1322 more secure, threaded fasteners 137 can also be added for connection and fixation.

[0161] Please refer to it again. Figure 11 and Figure 14 In one embodiment, the first frame 1321 and the second frame 1322 are not provided with a first connecting part 13212 and a first mating part 13222, but are connected and fixed by threaded fasteners 137 passing through the gap between two adjacent battery cells 13111.

[0162] Please refer to it again. Figure 12 and Figure 13In one embodiment, the first hole seat 13211 includes a first receiving portion 132111 and a first limiting portion 132112.

The second receiving portion 132211 is a second through hole opened in the second frame 1322. The second limiting portion 132212 is a second locking piece disposed on the side of the second frame 1322 opposite to the first frame 1321. The second locking piece partially covers the second through hole.

[0164] With this configuration, the first receiving portion 132111 and the second receiving portion 132211 are formed in the first through hole and the second through hole of the first frame 1321 and the second frame 1322, respectively. When they are engaged, they are used to receive and lock the opposite ends of a battery cell 13111. The first and second locking plates, which are set opposite to each other, can prevent the battery cell 13111 from sliding out of the first through hole or the second through hole. The battery cell 13111 is not easy to move within the hole seat, which ensures the installation stability of the battery cell 13111 and improves the safety of the battery cell 13111 during use.

The detection chip 171 is connected to the conductive element 133 and is used to measure the voltage of each battery assembly 1311. One end of the data feedback connector is connected to the detection chip 171, and the other end is communicatively connected to the electronic control board 16, for feeding back the voltage data measured by the detection chip 171 to the electronic control board 16.

[0172] With this configuration, the detection chip 171 of the voltage monitor 17 is connected to the conductive component 133, and one end of the data feedback connector is connected to the detection chip 171, while the other end is connected to the control board 16.

The control board 16 can then adjust the battery module 1311 based on the voltage data, facilitating performance testing of the battery module 1311 and improving the safety of the power supply module 10.

[0173] It is understandable that the number of voltage detectors corresponds to the number of battery modules 1311. When the voltage of a certain battery module 1311 has a problem, the electronic control board 16 can discard that battery module 1311 and allow other battery modules 1311 to be used normally.

The temperature sensing end is attached to the battery cell 13111, and the signal output end is communicatively connected to the electronic control board 16.

[0176] With this configuration, the temperature sensor 18 is attached to the cell 13111 at the temperature sensing end, and the signal output end is connected to the control board 16 for communication. Since the battery temperature will rise during use, excessively high temperature will have a huge impact on the battery performance and lifespan, and may even cause safety problems such as thermal runaway. The temperature sensor 18 is convenient for detecting the battery temperature, and the control board 16 can control the battery to stop using after receiving a high temperature signal. This facilitates the performance testing of the battery pack 1311 and improves the safety of the power supply module 10.
