DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0018] Please refer to Figure 1-Figure 2 As shown, the present application proposes a battery charging box 1, and the user can select a suitable charging interface 211 to connect to an external power source according to actual needs to improve the user's convenience.

[0019] The battery charging box 1 includes a feeding module 10, a charging module 20 and a discharging module 30. The feeding module 10 is used to store batteries to be charged; the charging module 20 is used to charge the batteries to be charged, and the charging module 20 includes a charging compartment 21 and an energy storage unit, the inlet of the charging compartment 21 is connected to the outlet of the feeding module 10, and the charging compartment 21 has a plurality of charging interfaces 211 for connecting to an external power source, and the energy storage unit is arranged in the charging compartment 21 and is electrically connected to the plurality of charging interfaces 211; the discharging module 30 is used to store fully charged batteries, and the inlet of the discharging module 30 is connected to the outlet of the charging compartment 21.

[0020] The following combination Figure 1-Figure 2 The specific structure of the battery charging box 1 is introduced in detail.

[0021] like Figure 1-Figure 2 As shown, the battery charging box 1 includes a feeding module 10 , a charging module 20 and a discharging module 30 .

[0022] The feed module 10 is used to store batteries to be charged. The feed module 10 includes a feed bin 11 (as the shell of the feed module 10). The batteries to be charged can flow into the chamber of the feed bin 11 from the entrance of the feed bin 11. The specific shape of the feed bin 11 is not limited here, and the designer can reasonably design it according to actual needs. For example, the outer contour shape of the feed bin 11 can be, but not limited to, a rectangular parallelepiped or a cylindrical shape; the specific preparation material of the feed bin 11 is not limited here, and the designer can reasonably choose it according to actual needs. For example, the preparation material of the feed bin 11 can be, but not limited to, PC (polycarbonate).

[0023] The charging module 20 is used to charge the battery to be charged, and the charging module 20 includes a charging compartment 21 and an energy storage unit (not shown in the figure).

[0024] The charging compartment 21 is the shell of the charging module 20. The specific shape of the charging compartment 21 is not limited here. Designers can make reasonable designs according to actual needs. For example, the outer contour shape of the charging compartment 21 can be, but not limited to, a quasi-rectangular or quasi-cylindrical shape. The specific preparation material of the charging compartment 21 is not limited here. Designers can make reasonable choices according to actual needs. For example, the preparation material of the charging compartment 21 is plastic or one of plastics. By designing the preparation material of the charging compartment 21 to be plastic or plastic, the cost of the battery charging box 1 can be effectively reduced.

[0025] The inlet of the charging bin 21 is connected to the outlet of the feeding bin 11 , so that the batteries to be charged can flow out of the chamber of the feeding bin 11 from the outlet of the feeding bin 11 and flow into the chamber of the charging bin 21 from the inlet of the charging bin 21 .

[0026] like Figure 1-Figure 2 As shown, the energy storage unit serves as the energy collection station of the charging module 20, and the energy storage unit is arranged in the charging compartment 21; the specific connection method between the energy storage unit and the charging compartment 21 is not limited here, and the designer can make a reasonable design according to actual needs; for example, when the energy storage unit and the charging compartment 21 are non-detachably connected, the energy storage unit can be, but not limited to, fixedly connected to the charging compartment 21 by gluing; for another example, when the energy storage unit and the charging compartment 21 are detachably connected, the energy storage unit can be, but not limited to, fixedly connected to the charging compartment 21 by at least one of screw connection, card connection or plug connection. Among them, the energy storage unit can include, but is not limited to, a battery.

[0027] The charging compartment 21 has multiple (more than two) charging interfaces 211, and the charging interface 211 is used to connect an external power supply. The energy storage unit is electrically connected to the multiple charging interfaces 211, so that when the charging interface 211 is connected to the external power supply, the external power supply can supply power to the energy storage unit through the charging interface 211. It should be noted that although there are multiple charging interfaces 211, the external power supply can only be connected to one charging interface 211 at a time to supply power to the energy storage unit. Of course, the charging compartment 21 can also have a direct charging interface (not shown in the figure), which is not electrically connected to the above-mentioned energy storage unit. When the direct charging interface is connected to the external power supply through a charging cable, the electric energy provided by the external power supply can directly charge the battery to be charged.

[0028] The discharge module 30 is used to store fully charged batteries, and the discharge module 30 includes a discharge bin 31 (as the shell of the discharge module 30); there is no limitation on the specific shape of the discharge bin 31, and designers can make reasonable designs according to actual needs. For example, the outer contour shape of the discharge bin 31 can be but is not limited to a rectangular or cylindrical shape; there is no limitation on the specific preparation material of the discharge bin 31, and designers can make reasonable choices according to actual needs. For example, the preparation material of the discharge bin 31 can be but is not limited to PC (polycarbonate).

[0029] The inlet of the discharge bin 31 is connected to the outlet of the charging bin 21 , so that fully charged batteries can flow out of the chamber of the charging bin 21 from the outlet of the charging bin 21 and flow into the chamber of the discharge bin 31 from the inlet of the discharge bin 31 .

[0030] Based on the battery charging box 1 in the embodiment of the present application, by designing multiple charging interfaces 211, compared with designing only one charging interface 211, other charging interfaces 211 can be used as backup interfaces. When some of the charging interfaces 211 are damaged, users can still choose to connect the remaining charging interfaces 211 to an external power source so that the external power source charges the energy storage unit, thereby improving the convenience of using the charging battery box; by designing multiple charging interfaces 211 to be electrically connected to the energy storage unit, the user can select one of the charging interfaces 211 to connect to the external power source each time according to actual needs so that the external power source charges the energy storage unit. At this time, the battery charging box 1 is equivalent to a mobile power source, which can improve the convenience of using the battery charging box 1.

[0031] Furthermore, if Figure 1 As shown, multiple charging interfaces 211 are provided on the back 215 of the charging compartment 21. It should be noted that the arrangement of the multiple charging interfaces 211 on the back 215 of the charging compartment 21 can be arbitrary; for example, the multiple charging interfaces 211 can be arranged at intervals on the back 215 of the charging compartment 21 along the length direction of the charging compartment 21; for another example, the multiple charging interfaces 211 can also be arranged at intervals on the back 215 of the charging compartment 21 along the width direction of the charging compartment 21. By providing multiple charging interfaces 211 on the back 215 of the charging compartment 21, it is convenient for users to connect the charging cable to an external power source so that the external power source supplies power to the energy storage unit.

[0032] Furthermore, if Figure 1As shown, the multiple charging interfaces 211 include a first interface 212 and a second interface 213. The first interface 212 and the second interface 213 are both electrically connected to the energy storage unit. The type of the first interface 212 is a type-C interface, and the type of the second interface 213 is a USB interface. By designing the first interface 212 as a type-C interface and the second interface 213 as a USB interface, it is convenient for users to use different types of charging cables to connect an external power source to the type-C interface or the USB interface, so that the external power source supplies power to the energy storage unit, thereby improving the convenience of the external power source supplying power to the battery charging box 1.

[0033] Furthermore, the energy storage unit includes a main battery (not shown in the figure) and a secondary battery (not shown in the figure), the main battery is arranged in the charging compartment 21 and is electrically connected to the first interface 212 and the second interface 213, and the secondary battery is arranged in the charging compartment 21 and is electrically connected to the first interface 212 and the second interface 213.

[0034] Among them, the main battery is used as one of the energy collection stations of the energy storage unit. The main battery is electrically connected to the first interface 212 and the second interface 213, so that the external power source charges the main battery through one of the first interface 212 and the second interface 213. The specific connection method between the main battery and the charging compartment 21 is not limited here, and the designer can make a reasonable design according to actual needs; for example, when the main battery and the charging compartment 21 are connected in a non-detachable manner, the main battery can be, but not limited to, fixedly connected to the charging compartment 21 by gluing; for another example, when the main battery and the charging compartment 21 are connected in a detachable manner, the main battery can be, but not limited to, fixedly connected to the charging compartment 21 by at least one of screw connection, card connection or plug connection.

[0035] The secondary battery serves as another energy collection station of the energy storage unit. The secondary battery is electrically connected to the first interface 212 and the second interface 213, so that the external power source can charge the secondary battery through one of the first interface 212 and the second interface 213. The specific connection method between the secondary battery and the charging compartment 21 is not limited here, and designers can make reasonable designs according to actual needs; for example, when the secondary battery and the charging compartment 21 are non-detachable, the secondary battery can be, but not limited to, fixedly connected to the charging compartment 21 by gluing; for another example, when the secondary battery and the charging compartment 21 are detachably connected, the secondary battery can be, but not limited to, fixedly connected to the charging compartment 21 by at least one of screw connection, snap connection or plug connection. It should be noted that the secondary battery and the main battery may be the same or different in parameters such as rated voltage, rated current, and rated capacity.

[0036] By designing the main battery and the auxiliary battery, the main battery and the auxiliary battery cooperate with each other to charge the battery to be charged, so that the overall battery capacity of the battery charging box 1 is larger, which can effectively improve the battery life of the battery charging box 1 and can be suitable for more application scenarios.

[0037] The charging module 20 also includes a control unit (not shown in the figure). On the one hand, the control unit serves as a structural component in the charging module 20 for controlling the main battery or the auxiliary battery to supply power to the battery to be charged. The control unit is arranged in the charging compartment 21 and is electrically connected to the main battery and the auxiliary battery. The specific structure of the control unit is not limited. Designers can make reasonable designs according to actual needs. For example, the control unit can include but is not limited to an MCU (Microcontroller Unit).

[0038] The control unit can monitor the current power of the secondary battery in real time, and the control unit can compare the current power of the secondary battery with its preset threshold power. It should be noted that the specific meaning of "threshold power" is not limited here, and the designer can set it in advance according to actual needs; for example, "threshold power" can be understood as the minimum power of the secondary battery that can normally supply power to the battery to be charged, such as 5% of the total power of the secondary battery, or 10% of the total power of the secondary battery.

[0039] When the current power of the secondary battery is greater than the threshold power, the battery charging box 1 is in the first power supply mode, in which the control unit controls the secondary battery to charge the battery to be charged alone; when the current power of the secondary battery is less than or equal to the threshold power, the battery charging box 1 is in the second power supply mode, in which the control unit controls the main battery to charge the battery to be charged alone. In other words, as long as the current power of the secondary battery is greater than the preset threshold power, the control unit will control the secondary battery to charge the battery to be charged in priority to the main battery, until the current power of the secondary battery is less than or equal to the above-mentioned preset threshold power, the control unit will control the secondary battery to stop charging the battery to be charged, and as long as the battery to be charged still has power demand, the control unit will continue to control the main battery to charge the battery to be charged alone.

[0040] The control unit is designed to compare the current power of the secondary battery with a preset threshold power, and when the current power of the secondary battery is greater than the preset threshold power, the control unit controls the secondary battery to charge the battery to be charged alone, so that the battery charging box 1 is in the first power supply mode in which the secondary battery charges the battery to be charged alone in preference to the main battery, and until the current power of the secondary battery is less than or equal to the corresponding preset threshold power, the control unit will control the main battery to charge the battery to be charged alone, so that the battery charging box 1 is in the second power supply mode, so that the battery charging box 1 can uninterruptedly charge the battery to be charged by switching between the secondary battery and the main battery.

[0041] On the other hand, the control unit serves as a structural component in the charging module 20 for controlling the main battery or the auxiliary battery to receive electrical energy provided by the external power supply. The battery charging box 1 also has a charging mode. In the charging mode, one of the first interface 212 and the second interface 213 is used to connect to the external power supply, and the control unit controls the external power supply to preferentially supply power to the main battery through one of the first interface 212 and the second interface 213 until the current power of the main battery is equal to its rated power, and the external power supply then supplies power to the auxiliary battery through one of the first interface 212 and the second interface 213. In other words, when the battery charging box 1 is in the charging mode, as long as the current power of the main battery has not reached its rated power, the control unit will control the external power supply to preferentially supply power to the main battery until the current power of the main battery reaches its rated power, and the control unit will then control the external power supply to supply power to the auxiliary battery.

[0042] Furthermore, if Figure 1-Figure 2 As shown, the charging bin 21 is located between the feed bin 11 and the discharge bin 31, and the outlet of the feed bin 11 is connected to the inlet of the charging bin 21, and the outlet of the charging bin 21 is connected to the inlet of the discharge bin 31. By arranging the charging bin 21 between the feed bin 11 and the discharge bin 31, the feed bin 11, the charging bin 21 and the discharge bin 31 are stacked in sequence, so that the battery to be charged flows from the inlet of the feed bin 11 into the chamber of the feed bin 11, flows out of the chamber of the feed bin 11 through the outlet of the feed bin 11 and flows into the chamber of the charging bin 21 from the inlet of the charging bin 21, so that the energy storage unit charges the battery to be charged, until the battery to be charged is fully charged, and the fully charged battery flows out of the chamber of the charging bin 21 from the outlet of the charging bin 21 and flows into the chamber of the discharge bin 31 from the inlet of the discharge bin 31, thereby realizing the charging process of the entire battery to be charged.

[0043] Furthermore, if Figure 1-Figure 2As shown, a heat dissipation structure 40 is provided on at least one of the front 214 of the charging compartment 21 and the back 215 of the charging compartment 21. By designing the heat dissipation structure 40 on the front 214 of the charging compartment 21 and / or the back 215 of the charging compartment 21, the heat dissipation structure 40 can timely discharge the heat generated by the energy storage unit in the process of charging the battery to be charged to the outside of the charging compartment 21, avoid heat accumulation in the charging compartment 21, and effectively improve the safety of the battery charging box 1.

[0044] Among them, the heat dissipation structure 40 can be a physical structure arranged on the front side 214 of the charging compartment 21 and / or the back side 215 of the charging compartment 21, and the heat dissipation structure 40 can also be a virtual structure arranged on the front side 214 of the charging compartment 21 and / or the back side 215 of the charging compartment 21; for example, when the heat dissipation structure 40 is a physical structure arranged on the front side 214 of the charging compartment 21 and / or the back side 215 of the charging compartment 21, the heat dissipation structure 40 can be a heat dissipation fin, and the heat dissipation fin can be integrally formed on the front side 214 of the charging compartment 21 and / or the back side 215 of the charging compartment 21 by injection molding or 3D printing; for another example, when the heat dissipation structure 40 is a virtual structure arranged on the front side 214 of the charging compartment 21 and / or the back side 215 of the charging compartment 21, the heat dissipation structure 40 can be a heat dissipation channel, and the heat dissipation channel is formed on the front side 214 of the charging compartment 21 and / or the back side 215 of the charging compartment 21.

[0045] In the embodiment of the present application, the heat dissipation structure 40 includes a plurality of heat dissipation holes 41 formed on the front 214 of the charging compartment 21 and the back 215 of the charging compartment 21. By designing the heat dissipation holes 41, the heat dissipation holes 41 can discharge the heat generated by the energy storage unit in the process of charging the battery to be charged from the charging compartment 21 in a timely manner, avoid heat accumulation in the charging compartment 21, and effectively improve the safety of the battery charging box 1. Specifically, the plurality of heat dissipation holes 41 located on the front 214 of the charging compartment 21 are arranged in a rectangular array, and the plurality of heat dissipation holes 41 located on the back 215 of the charging compartment 21 are also arranged in a rectangular array, and the plurality of heat dissipation holes 41 located on the front 214 of the charging compartment 21 and the plurality of heat dissipation holes 41 located on the back 215 of the charging compartment 21 are staggered in the height direction of the charging compartment 21.
