Description

Technical field:

[0001] The utility model relates to the technical field of energy storage power supplies, in particular to an energy storage power supply with separable packaging. Background technology:

[0002] Due to the limited coverage area of the public power grid, energy storage power supplies play the role of supplying power to electricity terminals in areas not covered by the public power grid. When a disaster occurs, the power transmission of the public power grid is interrupted, and energy storage power supplies become one of the limited options for power supply. Especially when people engage in outdoor activities, outdoor energy storage power supplies can become the only source of power for electricity terminals.

[0003] Energy storage power supplies are safe, portable, stable, and environmentally friendly small-scale energy storage systems that utilize built-in high-energy-density lithium-ion batteries to provide stable AC and DC power output. They can be considered "large-scale outdoor power banks," typically carrying 0.2KWh to 2KWh of power, with a higher output power range of 100W to 2200W. Equipped with multiple interfaces such as AC, DC, Type-C, USB, and PD, they are compatible with mainstream electronic devices and are widely used in scenarios such as emergency preparedness and outdoor travel.

[0004] Currently, there is an energy storage power supply on the market. For example, Chinese invention patent publication number CN117791763A discloses an energy storage power supply comprising: a housing, a built-in battery, an inverter, and an electronic component. The housing defines a cavity and is provided with an air outlet. A fan is provided inside the air outlet. The built-in battery is mounted at the bottom of the cavity. The inverter is mounted above the built-in battery and is connected to the built-in battery circuit. The electronic component controls the operation of the energy storage power supply. The inverter comprises an inverter PCB and an inverter device. The inverter PCB is arranged horizontally in the cavity, near the top of the housing. The inverter device extends downward from the inverter PCB, such that the inverter is installed in an inverted position. A heat dissipation channel is formed between the inverter PCB and the built-in battery. The air outlets are located at both ends of the heat dissipation channel to form upper air outlets and communicate with the heat dissipation channel for heat dissipation.

[0005] However, this existing energy storage power supply still has the following shortcomings:

[0006] In this technical solution, heat dissipation is achieved by providing an air vent on the housing, a fan inside the air vent, and a heat dissipation channel between the inverter PCB board and the built-in battery. However, this will undoubtedly increase the overall volume of the energy storage power supply and increase the difficulty of carrying and transporting it. In addition, the inverter is upside down in the cavity, but the inverter cannot be stored in the housing after the built-in battery is removed, and it cannot be transported in separate parts. During transportation, it can only be transported as a whole, which takes up a lot of space, increases transportation costs, and is inconvenient for transportation management.

[0007] In view of this, the inventors propose the following technical solutions. Utility model content:

[0008] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a separable packaged energy storage power supply.

[0010] an inverter, which is detachably mounted on the housing and is provided with a plurality of interfaces;

[0011] a battery module, which is disposed in the cavity and is used to power the inverter;

[0012] The width and length of the inverter are both smaller than the width and length of the cavity, and the width of the inverter is smaller than the height of the cavity, so that the controller can be accommodated in the cavity after the battery module is removed.

[0013] Furthermore, in the above technical solution, a first load-bearing flange and a second load-bearing flange for supporting the inverter are provided in the cavity, and the distance between the first load-bearing flange and the second load-bearing flange is smaller than the width of the inverter, so that the inverter can be placed horizontally on the first load-bearing flange and the second load-bearing flange.

[0014] Furthermore, in the above technical solution, a first screw hole and a second screw hole are respectively provided on both sides of the inverter, and correspondingly, a first through-hole and a second through-hole are respectively provided on both sides of the shell, and a first screw passes through the first through-hole and is screwedly installed in the first screw hole, and a second screw passes through the second through-hole and is screwedly installed in the second screw hole, so that the inverter can be detachably fixed to the shell.

[0015] Furthermore, in the above technical solution, a first handle portion and a second handle portion for facilitating pulling the energy storage power supply are respectively provided on both sides of the shell.

[0016] Furthermore, in the above technical solution, a control interface is provided on the inverter, and the interface on the inverter includes a first interface and a second interface for external power supply.

[0017] Furthermore, in the above technical solution, the first interface is a DC interface, which includes at least two of a USB interface, a PD interface and a Type-C interface, and the second interface is an AC electrical interface.

[0018] Furthermore, in the above technical solution, a plurality of brake wheel structures for moving the energy storage power supply are detachably provided at the bottom of the shell.

[0019] Furthermore, in the above technical solution, the inverter is provided with a power connection line, and the inverter is also provided with a plurality of knobs for controlling the inverter beside the power connection line.

[0021] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: in the present invention, by designing the inverter to be smaller than the cavity opening, and the width of the inverter is also designed to be smaller than the height of the cavity, after the battery module is disassembled, the inverter can be stored in the cavity, effectively realizing the separate transportation of the battery module and the inverter, greatly reducing the transportation space occupied, facilitating subpackaging and packaging, saving transportation costs, and facilitating transportation management.

[0028] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0029] See Figures 1 to 6 As shown, a detachably packaged energy storage power supply comprises: a shell 1, in which a cavity 10 is formed; an inverter 2, which is detachably mounted on the shell 1 and provided with a plurality of interfaces 21; a battery module 3, which is disposed in the cavity 10 and is used to supply power to the inverter 2; the width and length of the inverter 2 are both smaller than the width and length of the cavity 10, and the width of the inverter 2 is smaller than the height of the cavity 10, so that the inverter 2 can be accommodated in the cavity 10 after the battery module 3 is removed.

[0030] In the present invention, by designing the inverter 2 to be smaller than the opening of the cavity 10, and the width of the inverter 2 is also designed to be smaller than the height of the cavity 10, after the battery module 3 is disassembled, the inverter 2 can be vertically stored in the cavity 10, effectively realizing the separate transportation of the battery module 3 and the inverter 2, greatly reducing the space occupied by transportation, saving transportation costs, and facilitating transportation management.

[0031] Combine Figure 5 As shown, the cavity 10 is provided with a first load-bearing flange 101 and a second load-bearing flange 102 for supporting the inverter 2. The distance between the first load-bearing flange 101 and the second load-bearing flange 102 is smaller than the width of the inverter 2, so that the inverter 2 can be placed horizontally on the first load-bearing flange 101 and the second load-bearing flange 102. Here, since it is necessary to store the inverter 2 in the cavity 10, in this technical solution, the size of the inverter 2 is designed to be smaller than the size of the cavity 10. In this way, the inverter 2 will slide into the cavity 10 during installation and it will be difficult to be arranged horizontally on the shell 1. Therefore, the inverter 2 needs to be supported by the first load-bearing flange 101 and the second load-bearing flange 102 so that the inverter 2 can be arranged horizontally on the shell 1 without sliding into the cavity 10. It should be noted that in order not to affect the vertical storage of the inverter 2 in the cavity 10, the first load-bearing flange 101 and the second load-bearing flange 102 are both distributed on the long side of the shell 1. When the inverter 2 is stored vertically, they will not form an obstruction to the inverter 2.

[0032] The inverter 2 has first screw holes 23 and second screw holes 22 on both sides, respectively. Correspondingly, the housing 1 has first through-holes 110 and second through-holes 120 on both sides, respectively. A first screw 81 passes through the first through-hole 110 and is screwed into the first screw hole 23, while a second screw 91 passes through the second through-hole 120 and is screwed into the second screw hole 22, allowing the inverter 2 to be removably fixed to the housing 1. In this embodiment, there are two first screws 81, and accordingly, there are two first through-holes 110 and two first screw holes 23; there are two second screws 91, and accordingly, there are two second through-holes 120 and two second screw holes 22.

[0033] The housing 1 is provided with a first handle 11 and a second handle 12 on either side for facilitating the lifting of the energy storage power supply. The bottom of the housing 1 is detachably provided with a plurality of brake wheel structures 50 for moving the energy storage power supply. The brake wheel structures 50 are capable of moving 360° in all directions and can quickly move to a designated position and stop when in use, providing fast and stable operation. Furthermore, the first handle 11 and the second handle 12 are provided for the human hand to pull the energy storage power supply, further facilitating operation by the operator.

[0034] The inverter 2 is provided with a control interface 4. The interface 21 on the inverter 2 includes a first interface 211 and a second interface 212 for external power supply. The first interface 211 includes multiple interfaces such as a USB interface, a PD interface, and a Type-C interface, while the second interface 212 is an AC interface. Here, the most basic function of the energy storage power supply is still to provide stable external power supply. In this embodiment, the inverter 2 converts the DC energy of the battery module 3 into AC energy, and then supplies power to the outside through the interface 21.

[0035] The inverter 2 is equipped with a power connection cable 60. Next to the power connection cable are several knobs 61 for controlling the inverter 2. These knobs 61 include a start knob 611 and a mode selector knob 612. The start knob 611 is used to start and stop the inverter, while the mode selector knob 612 allows the user to switch between different operating modes, such as grid-connected mode, disconnect mode, and fault shutdown mode. By rotating these knobs, the operator can achieve precise control over the operation of the inverter 2.

[0036] The housing 1 is rectangular in shape; the inverter 2 is also rectangular in shape, with first and second heat dissipation holes 71 and 72 respectively provided on both sides of the inverter 2 for heat dissipation. The first and second heat dissipation holes 72 on both sides of the inverter 2 effectively create air convection, dissipating the high heat generated by the inverter 2.

[0037] To sum up, in the present invention, by designing the inverter 2 to be smaller than the opening of the cavity 10, and the width of the inverter 2 is also designed to be smaller than the height of the cavity 10, after the battery module 3 is disassembled, the inverter 2 can be stored in the cavity 10, effectively realizing the separate transportation of the battery module 3 and the inverter 2, greatly reducing the transportation space, facilitating subpackaging and packaging, saving transportation costs, and facilitating transportation management.

[0038] The storage method of the utility model is as follows: first, remove the first screw 81 and the second screw 91, remove the inverter 2, further, take out the battery module 3 from the cavity 10, and pack the battery module 3, further, place the inverter 2 vertically in the cavity 10, further, remove the brake wheel structure 50 on the housing 1 and store it in the cavity 10, further, combine Figure 6 As shown, buffer blocks 100 for buffering are placed in the cavity 10 and at the corners of the shell 1. The buffer blocks 100 include at least one of a sponge block and a foam block. Furthermore, the shell 1 is placed in a packing box 200 for packing. After storage, the space occupied by the shell is greatly reduced, which is convenient for transportation and management.

[0039] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made based on the structure, features and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
