[0040] Please refer to Figures 1 to 6 , a storage bag 100 provided by an embodiment of the present utility model includes a bag body 101 and an electric heating component 103. The bag body 101 is provided with a receiving cavity 102 for receiving the energy storage power supply 200. The electric heating component 103 is detachably disposed in the receiving cavity 102. The electric heating component 103 includes an electric heating element 108 and a power supply line 105 connected to each other. The power supply line 105 is used for electrically connecting to the power supply interface 106 of the energy storage power supply 200 to enable the energy storage power supply 200 to supply power to the electric heating element 108.

[0041] Specifically, the storage bag 100 is used for accommodating and protecting the energy storage power supply 200. It is internally provided with a receiving cavity 102, and the energy storage power supply 200 is placed in the receiving cavity 102. The energy storage power supply 200 may include a battery module, an inverter and a housing. The inverter and the battery module are disposed in the housing. The inverter can convert the direct current output by the battery module into alternating current and output it externally. The battery module may include a battery, and the battery can be a lithium iron phosphate battery, a lithium battery, a lead-acid battery, a nickel-metal hydride battery or other rechargeable batteries, which have the ability to provide electric energy. The energy storage power supply 200 can supply power to the electric heating element 108. Through the heating function of the electric heating element 108, the temperature in the receiving cavity 102 can be maintained within a suitable range, especially in a low-temperature environment, to ensure that the energy storage power supply 200 can be used normally.

[0042] Optionally, the electric heating element 108 can be a heating wire made of a high-resistance material, such as nickel-chromium alloy, which converts electrical energy into heat energy to provide heat inside the receiving cavity 102, thereby heating the energy storage power supply 200 to ensure its normal operation in a low-temperature environment.

[0043] The power supply line 105 is used to transmit the electric energy of the energy storage power supply 200 to the electric heating element 108. It is usually made of copper wire or other conductive materials and has an insulating coating on its surface, capable of withstanding the voltage and current requirements of the energy storage power supply 200. One end of the power supply line 105 is connected to the electric heating element 108, and the other end is connected to the power supply interface 106 of the energy storage power supply 200. Among them, the power supply interface 106 is an output interface provided on the energy storage power supply 200 for connecting to the power supply line 105. The power supply interface 106 can be a common USB interface, a DC socket, or other special interfaces, depending on the design of the energy storage power supply 200. The power supply interface 106 ensures that the electric energy can be effectively transmitted to the electric heating component 103, causing the electric heating element 108 to generate heat.

[0044] In the embodiment of the present utility model, the electric heating component 103 is detachably disposed in the accommodation cavity 102, so that the user can replace or maintain the electric heating component 103 according to needs, and at the same time provides higher flexibility to meet different heating requirements.

[0045] In the above-mentioned storage bag 100, the energy storage power supply 200 powers the electric heating element 108, causing the electric heating element 108 to generate heat, thereby heating the energy storage power supply 200 located in the accommodation cavity 102. Even when the storage bag 100 is in a low-temperature environment, the temperature in the accommodation cavity 102 can still be maintained within the range where the energy storage power supply 200 can be used normally, thus ensuring that the energy storage power supply 200 can be used normally in a low-temperature environment.

[0046] Further, please refer to Figure 2 and Figure 3 , in some embodiments, the electric heating component 103 includes a heat conduction layer 107 and a heat insulation layer 109, and the electric heating element 108 is clamped between the heat conduction layer 107 and the heat insulation layer 109.

[0047] Specifically, the electric heating element 108 can be connected to the energy storage power supply 200 through the power supply line 105 to convert the electric energy of the energy storage power supply 200 into heat energy. The electric heating element 108 is clamped between the heat conduction layer 107 and the heat insulation layer 109, so that the heat conduction layer 107 and the heat insulation layer 109 can protect the electric heating element 108. The heat conduction layer 107 is a material layer for heat conduction, aiming to transfer heat to the accommodation cavity 102. The heat insulation layer 109 is a material layer for isolating and blocking heat, aiming to prevent heat from being conducted to areas that do not need to be heated. In the electric heating component 103, the heat conduction layer 107 is usually made of materials with good heat conduction performance, such as PEVA (polyethylene vinyl acetate), PVC (polyvinyl chloride), heat-conducting silica gel, or plastics containing heat-conducting fillers, etc. These materials can effectively conduct the heat generated by the electric heating element 108 from the electric heating element 108 to the accommodation cavity 102. The heat insulation layer 109 is usually made of materials with a low heat conduction coefficient, such as foam plastics, ceramic fibers, aluminosilicate fibers, etc. These materials can effectively isolate heat and prevent heat energy from escaping.

[0048] In the above embodiments, the first heat-conducting layer 107 is disposed on one side of the electrothermal element 108, and the heat-insulating layer 109 is disposed on the other side of the electrothermal element 108, ensuring that the heat generated by the electrothermal element 108 can be evenly conducted to the accommodation cavity 102, while preventing the heat energy from escaping in the direction away from the accommodation cavity 102. The power supply line 105 is electrically connected to the power supply interface 106 of the energy storage power supply 200 and the electrothermal element 108 respectively, so as to ensure that the electric energy can be quickly and effectively converted into heat energy to maintain the efficient operation of the electrothermal assembly 103.

[0049] Optionally, in one embodiment, the heat-conducting layer 107 is disposed on the side of the electrothermal element 108 facing the accommodation cavity 102, and the heat-insulating layer 109 is disposed on the side of the electrothermal element 108 facing away from the accommodation cavity 102. A buffer filler is provided between the heat-insulating layer 109 and the electrothermal element 108 for absorbing and reducing the vibration or mechanical shock generated during the operation of the electrothermal assembly 103, thereby protecting the electrothermal assembly 103 from damage and extending the service life of the electrothermal assembly 103.

[0050] Optionally, in one embodiment, the heat-conducting layer 107 is disposed on the side of the electrothermal element 108 facing the accommodation cavity 102, and the heat-insulating layer 109 is disposed on the side of the electrothermal element 108 facing away from the accommodation cavity 102. After the power supply line 105 is connected to the electrothermal element 108 through the connection port, the power supply line 105 passes through and is connected to the temperature control component 111 at the corner edge position of the heat-conducting layer 107. Specifically, at the position where the power supply line 105 passes through, the power supply line 105 is connected to the heat-conducting layer 107 through a soft glue 130 (such as 16SR soft glue) to ensure the stability of the connection between the power supply line 105 and the electrothermal element 108.

[0051] Furthermore, please refer to Figure 2 and Figure 3 , in some embodiments, the electrothermal assembly 103 includes a border member 110, and the border member 110 covers the peripheries of the heat-conducting layer 107, the electrothermal element 108, and the heat-insulating layer 109.

[0052] Specifically, the border member 110 is a protective and connecting member disposed at the edge portion of the electrothermal assembly 103 around the core components (such as the electrothermal element 108, the heat-conducting layer 107, and the heat-insulating layer 109). The edge portions of the electrothermal element 108, the heat-conducting layer 107, and the heat-insulating layer 109 are connected together by the border member 110. Exemplarily, the border member 110 can be fixedly connected to the peripheries of the heat-conducting layer 107, the electrothermal element 108, and the heat-insulating layer 109 by means of adhesion, stitching, heat sealing, etc. The border member 110 can be made of a waterproof or dustproof material. In one example, the density of the material can be 300D (Denier), that is, the fiber weight per 9000 meters is 300 grams.

[0053] In the above-described embodiments, the edge wrapping member 110 connects to the peripheries of the heat conducting layer 107, the electrothermal member 108, and the heat insulating layer 109, which can maintain the relative positions among the layers and to a certain extent prevent the interlayer displacement or separation caused by external forces or vibrations during use, thereby ensuring the overall stability of the electrothermal assembly 103.

[0054] Further, please refer to Figure 2 and Figure 3 In some embodiments, a temperature control component 111 is provided on the power supply line 105, and the temperature control component 111 is used to control the switch of the electrothermal member 108 and the temperature of the electrothermal member 108.

[0055] Specifically, the temperature control component 111 is an electronic component used to monitor and adjust the temperature of the electrothermal member 108. The temperature control component 111 includes a temperature sensor, a control circuit, an electronic switch, etc. After the power supply line 105 is connected to the power supply interface 106 of the energy storage power supply 200, the electric energy provided by the energy storage power supply 200 can flow into the temperature control component 111 and the electrothermal member 108. The temperature sensor can monitor the temperature inside the accommodation cavity 102 in real time and transmit the measurement result to the control circuit to control the conduction and disconnection of the electronic switch. Exemplarily, when it is monitored that the temperature inside the accommodation cavity 102 is less than 35 degrees Celsius, the control circuit controls the electronic switch to conduct, allowing the electric energy to be transmitted from the energy storage power supply 200 to the electrothermal member so that the electrothermal member starts to work and converts the electric energy into heat energy. When it is monitored that the temperature inside the accommodation cavity 102 is greater than or equal to 35 degrees Celsius, the control circuit controls the electronic switch to disconnect, causing the electrothermal member to stop heating, thereby saving electric energy.

[0056] In the above-described embodiments, a temperature control component 111 is provided on the power supply line 105, which can monitor the temperature inside the accommodation cavity 102 in real time, thereby ensuring that the working state of the electrothermal member 108 can be adjusted in a timely manner.

[0057] Optionally, in one embodiment, the temperature control component 111 includes a first indicator light and a second indicator light. The first indicator light is used to display the working state of the electrothermal member, and the second indicator light is used to display the connection state of the energy storage power supply 200. For example, when the electrothermal member 108 is heating, the first indicator light is on; when the heating is completed, the first indicator light is off. When the energy storage power supply 200 is in a connected state with the power supply line 105, the second indicator light is on; when the energy storage power supply 200 is in a disconnected state from the power supply line 105, the second indicator light is off.

[0058] Further, please refer to Figure 7 and Figure 8 In some embodiments, the package body 101 includes a plurality of enclosures 112, and the plurality of enclosures 112 together enclose the accommodation cavity 102. The enclosure 112 includes a fabric layer 113 and a heat preservation layer 128, and the heat preservation layer 128 and the fabric layer 113 are arranged in sequence along the direction away from the accommodation cavity 102.

[0059] Specifically, in the embodiment of the present utility model, the package body 101 includes six enclosures 112 on the front, back, left, right, top and bottom. The six enclosures 112 together enclose a receiving cavity 102 that can accommodate the energy storage power supply 200. Each enclosure 112 includes a fabric layer 113 and a heat insulation layer 128. The heat insulation layer 128 and the fabric layer 113 are arranged in sequence along the direction away from the receiving cavity 102. The heat insulation layer 128 can, to a certain extent, prevent the heat in the receiving cavity 102 from dissipating to the outside of the receiving cavity 102.

[0060] Exemplarily, the fabric layer 113 can be made of wear-resistant and waterproof materials. For example, PU leather film material, and the fiber density can be 900D.

[0061] In the above embodiment, the enclosures 112 can enclose and define the space of the receiving cavity 102, providing a closed environment to accommodate and protect the energy storage power supply 200.

[0062] Exemplarily, the heat insulation layer 128 can be made of materials with good heat insulation performance such as pearl cotton, polyurethane foam (PU foam), polystyrene foam (EPS and XPS), etc.

[0063] Further, please refer to Figure 7 and Figure 11 , in some embodiments, the package body 101 includes a plurality of enclosures 112. The plurality of enclosures 112 together enclose the receiving cavity 102. The enclosure 112 includes a first enclosure 131. The first enclosure 131 is provided with a limiting device 132. The electric heating component 103 is limited to the side wall of the receiving cavity 102 through the limiting device 132.

[0064] Specifically, in the embodiment of the present utility model, the package body 101 includes six enclosures 112. The six enclosures 112 together enclose a receiving cavity 102 that can accommodate the energy storage power supply 200. The limiting device 132 refers to a device provided on the first enclosure 131 for fixing the electric heating component 103 to the side wall of the receiving cavity 102.

[0065] In the above embodiment, the first enclosure 131 is provided with a limiting device 132, which can, to a certain extent, prevent the electric heating component 103 from moving or shaking inside the package body 101, thereby ensuring that the electric heating component 103 can work stably.

[0066] Optionally, in one embodiment, the limiting device 132 can be a cloth bag structure. A cloth bag is attached or sewn on the first enclosure 131 of the bag body 101, and the electric heating component 103 can be inserted into the cloth bag, which fixes the electric heating component 103 on the side wall of the accommodating cavity 102. In one embodiment, the limiting device 132 can be a magic tape. One part of the magic tape is arranged on the inner side of the first enclosure 131, and the other part is fixed on the electric heating component 103. When the electric heating component 103 approaches the first enclosure 131, the two parts of the magic tape are adhered to each other, firmly fixing the electric heating component 103 on the side wall of the accommodating cavity 102. In one embodiment, the limiting device 132 can adopt a snap structure, for example, an elastic snap or a claw arranged on the first enclosure 131. The electric heating component 103 can be fixed in the snap by pressing, which is convenient for installation and disassembly, and can ensure the tightness and stability of the electric heating component 103. In one embodiment, the limiting device 132 can be one or more guide rails or chutes arranged along the inner surface of the first enclosure 131. The electric heating component 103 can be inserted and fixed in the guide rail by sliding, and this structure can effectively prevent the electric heating component 103 from moving in multiple directions. In one embodiment, the limiting device 132 can also adopt a fixed clamping member, such as an elastic clip or a fixture. The electric heating component 103 is fixed on the side wall of the accommodating cavity 102 by the clamping member, and by using the elastic characteristic of the clamping member, the vibration and impact force can be effectively absorbed to prevent the loosening of the electric heating component 103. In one embodiment, the limiting device 132 can be a magnetic adsorption structure, and magnetic materials or magnets are respectively arranged on the first enclosure 131 and the electric heating component 103, and the electric heating component 103 is fixed on the side wall by magnetic force.

[0067] Further, please refer to Figure 11 , in some embodiments, the limiting device 132 is an elastic band or a limiting pocket arranged on the enclosure 112.

[0068] Specifically, the limiting device 132 can be an elastic band arranged on the enclosure 112. The elastic band is made of an elastic material and has good elasticity and toughness. The two ends of the elastic band are respectively fixed at the two ends of the inner side of the enclosure 112. By tightening the elastic band to make it closely adhere to the inner side of the enclosure 112, the electric heating component 103 can pass through between the elastic band and the side wall of the enclosure 112 and closely adhere to the side wall of the accommodating cavity 102 under the elastic action of the elastic band, preventing it from moving or shaking inside the bag body 101. The elastic characteristic of the elastic band allows it to be adjusted according to the size and shape of the electric heating component 103 to adapt to different specifications of the electric heating component 103.

[0069] Specifically, the limiting device 132 can be a limiting pocket provided on the enclosure 112. The limiting pocket can be made of a heat-resistant and corrosion-resistant mesh material (such as high-strength nylon), and has good air permeability and flexibility. The opening part of the limiting pocket is fixed to the edge of the enclosure 112 to form a bag-like structure capable of accommodating the electric heating component 103. After the electric heating component 103 is placed in the limiting pocket, the elastic band of the limiting pocket can firmly fix it to the side wall of the accommodating cavity 102.

[0070] In the above embodiments, the telescopic band or the limiting pocket can prevent the electric heating component 103 from moving or shaking inside the package 101 to a certain extent, so as to ensure the stable operation of the electric heating component 103.

[0071] Furthermore, please refer to Figure 9 and Figure 10 , in some embodiments, the enclosure 112 further includes a second enclosure 133. The second enclosure 133 is disposed opposite to the first enclosure 131. A panel hole 120 is provided on the second enclosure 133. The package 101 includes a movable second cover plate 121.

In the fourth position, the second cover plate 121 opens the panel hole 120.

[0072] Specifically, in the embodiment of the present utility model, as Figure 7 shown, the package 101 includes 6 enclosures 112. The 6 enclosures 112 together form an accommodating cavity 102 that can accommodate the energy storage power supply 200. The panel hole 120 refers to a through hole provided on the second enclosure 133. When the second cover plate 121 opens the panel hole 120, it allows the panel of the energy storage power supply 200 to be exposed to the outside for the user to operate, inspect or maintain. Among them, the panel is the main area for the user to interact with the energy storage power supply 200, and provides functions such as monitoring, power input, power output, and operating equipment.

The limiting device 132 is used to limit the electric heating component 103 to the side wall of the accommodating cavity 102.

[0074] The second cover plate 121 is used to close or open the panel hole 120 as needed to meet the protection and operation requirements of the device. In the third position, the second cover plate 121 covers the panel hole 120, which is applicable to situations where a closed environment is required, such as when the energy storage power supply 200 does not need to dissipate heat or to protect the power supply from external factors during transportation. In the fourth position, the second cover plate 121 opens the panel hole 120 to facilitate user operation and maintenance.

[0075] In the above embodiment, the second cover plate 121 can flexibly switch between the third position and the fourth position, providing convenient access to the panel of the energy storage power supply 200 and supporting operation and maintenance requirements.

[0076] Optionally, in combination with Figure 9 and Figure 10 , the second direction is the front-back direction.
