Description

Technical Field

[0001] The present invention relates to the field of power tools, and particularly to a charging system and a multi-functional cabinet for rechargeable power tools. Background Art

[0002] Since the single battery equipped with a rechargeable power tool has a short battery life and is much less than the charging time, and there are a large number and various types of batteries, the management is cumbersome, and the battery life of a single battery far cannot meet the needs of the construction site. At present, the methods to improve the battery life of rechargeable power tools mainly include purchasing a large number of batteries and charging the batteries at the construction site. Purchasing a large number of batteries not only increases the construction cost and the difficulty of battery management, but also goes against the concept of green environmental protection construction; in recent years, the State Grid Corporation has made many clear regulations on the temporary power supply system at the construction site, such as "cable lines should be laid underground or overhead, not laid openly along the ground, and mechanical damage and medium corrosion should be avoided", "one machine, one switch, and one protection", etc., resulting in a complicated layout and long time-consuming for the safety measures of the temporary power supply system at the construction site. Therefore, charging the battery at the construction site not only takes up construction time but also increases safety risks. Therefore, it is proposed to develop a multi-functional cabinet for rechargeable power tools to integrate the functions of storage and charging, improve the battery life of rechargeable power tools, and improve the installation and construction efficiency of electrical equipment at the power construction site. Summary of the Invention

The power supply module includes a mains power supply and a mobile power supply. A switch is respectively connected in series to the first ends of the mains power supply and the mobile power supply. The second ends of the mains power supply and the mobile power supply are connected to one end of the charging module and the heat dissipation module. The charging module is connected in parallel with the heat dissipation module. The charging module includes a plurality of air switches and sockets. The heat dissipation module is a fan. The output ends of the charging module and the heat dissipation module are connected to one end of the switch. Each module is connected by wires.

[0005] Further, it further includes a leakage protector. One end of the leakage protector is connected to the power supply module, and the second end of the leakage protector is connected to the charging module and the heat dissipation module.

[0006] Further, a plurality of sockets in the charging module are connected in parallel with each other, and each socket is respectively connected in series with an air switch.

[0007] Further, the socket is an overcharging socket, and an intelligent chip is installed inside for detecting the charging power of the device.

[0008] Furthermore, the mobile power supply is a lithium iron phosphate battery, and the wire is a single-strand copper core wire with PVC insulation.

[0009] The present utility model also provides a multi-functional cabinet for rechargeable power tools, including a cabinet body and a cabinet door. The cabinet body is divided into multiple functional areas, and the functional areas sequentially form a charging functional area and a storage functional area from top to bottom. The charging functional area is provided with the charging system as described in any one of the above items. The sockets are respectively arranged on the back panel of the cabinet body in the charging functional area. The fan includes at least two, which are respectively arranged on both sides of the cabinet body in the charging functional area. The storage functional area is divided into a placement area and a drawer area from top to bottom. The cabinet door is arranged outside the placement area and the charging functional area.

[0010] Furthermore, the two fans have the same direction, one is used to blow in external air, and the other is used to blow out internal hot air.

[0011] Furthermore, the material of the cabinet body is painted cold-rolled steel plate.

[0012] Furthermore, a movable baffle is arranged in the placement area, and the placement area is divided into multiple spaces by the movable baffle.

[0013] Furthermore, it is characterized in that movable casters are installed at the bottom of the cabinet body. For the two movable casters on the side close to the cabinet door in the front, universal wheels are used, and for the two movable casters on the side close to the back panel of the cabinet body, single-direction wheels are used.

[0014] The multi-functional cabinet for rechargeable power tools integrating charging and storage provided by the present application is convenient and practical.

[0018] The present utility model will be further described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. Terms such as "upper", "lower", "left", "right", etc. cited in this specification are only for the convenience of description and are not used to limit the scope of implementation of the present utility model. Changes or adjustments to their relative relationships, without substantial changes in the technical content, should also be regarded as within the scope of implementation of the present utility model.

[0019] This embodiment aims to provide a charging system, as Figure 1 shown, the charging system includes a power supply module, a charging module and a heat dissipation module. The power supply module includes a mains power supply and a mobile power supply connected in parallel. The first ends of the mains power supply and the mobile power supply are respectively connected in series with the second ends of a switch. A lithium iron phosphate battery with a capacity of 22.4 Ah is used as the mobile power supply. The second ends of the mains power supply and the mobile power supply are connected to the first end of a leakage protector. The leakage protector uses a type C leakage protector. The second end of the type C leakage protector is connected to the charging module and the heat dissipation module. In this embodiment, there are five air switches and sockets in the charging module. The five sockets are connected in parallel. The socket is an anti-overcharging socket, which has functions of automatic power-off when fully charged, intelligent floating charge, and overload protection. It is internally equipped with an intelligent chip to detect the charging power of the device. Each anti-overcharging socket is respectively connected in series with an air switch. The heat dissipation module includes a fan, and the fan is connected in parallel with the charging module. One ends of the charging module and the heat dissipation module are respectively connected to the first end of the switch connected in series with the mains power supply and the mobile power supply. The modules are connected by polyvinyl chloride (PVC) insulated single-strand copper core wires.

[0020] In this embodiment, the charging power of the device is detected by the anti-overcharging socket. When the storage battery is close to being fully charged, it can automatically switch to the intelligent floating charge mode, and the power supply is automatically cut off after the current is saturated. When the load borne by the socket exceeds the rated power, the power supply will be automatically cut off, and pressing the switch button again can continue charging. This is beneficial to maintaining the storage battery, extending the service life of the storage battery, and is green and environmentally friendly. Moreover, the power supply system of this embodiment adopts a dual-power free-switching dual-power supply mode. The mobile power supply charging mode is applicable to power construction sites and power emergency repairs. When five sockets are charging simultaneously, the lithium iron phosphate battery with a capacity of 22.4 Ah can provide a battery life of 10 hours. The mains power supply charging mode is applicable outside the construction time, and the storage battery is charged through a power cord connected to other power sources such as domestic electricity.
