Description

Technical Field

[0001] The present technical solution relates to the technical field of light string control boxes, and in particular to a control box. Background Art

[0002] A light string control box is an electronic device used to control and manage holiday lights (such as LED light strings, neon lights, etc.). It has preset multiple lighting modes and sets the on and off times of the lights. Some control boxes support remote control operation, allowing users to adjust the lighting effects remotely.

[0003] For example, a solar LED light string in China with patent publication number CN211551241U includes a power supply component and a light string storage box. The power supply component is electrically connected to the light string storage box through a power supply line. The power supply component includes a solar panel, a transformer, a controller and a battery connected in sequence. The light string storage box includes a pulley retractor and an LED light string inserted into the pulley retractor. The pulley retractor includes a bracket, a pulley block and a driver. The pulley block is arranged side by side in the bracket. The output end of the driver is connected to the pulley block. The input end of the LED light string and the input end of the driver are connected to the battery through the controller.

[0004] The above-mentioned solar LED light string has an existing controller connected to a battery and powered by the battery. In order to make power supply easier, some battery boxes are powered by solar energy. However, in actual use, the number of days that solar energy can be used continuously after being fully charged is relatively short, and using dry cell power alone can only last for about 15 days. The service life is relatively short and needs to be improved. Summary of the Invention

[0005] In order to improve the problem of short service life caused by solar energy or battery power supply, this technical solution provides a control box.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A control box includes a box base and a box cover arranged on the box base, the box cover is hinged to the box base, and the box cover is flipped to cover the box base, the box base is provided with a mounting groove, a solar panel is installed in the mounting groove, the box base is also provided with a rechargeable battery, a circuit board is connected between the rechargeable battery and the solar panel, the rechargeable battery is used to power a light string, the box base is also provided with a battery mounting box, the battery mounting box is used for installing the battery, when the battery is installed in the battery mounting box, the battery is connected to the circuit board to power the light string.

[0008] Through the above technical solution, when the control box is in normal use, the solar panel is installed in the installation groove of the box seat. The solar panel can receive solar energy as energy and convert it into electrical energy. The box cover is flipped along the hinge axis to open the inside of the box seat. A rechargeable battery and a battery mounting box are installed inside the box seat. The rechargeable battery can store and receive electrical energy from the solar panel, and cooperate with the battery in the battery mounting box to provide power. The priority of the rechargeable battery power supply is set higher than the battery power supply. The power supply mode can be manually switched through the control button to improve operability.

[0009] Under the condition of sufficient solar energy, the rechargeable battery supplies power to the light string through the circuit board. The energy released by the rechargeable battery after a single full charge can support the use of lights for a whole day. In order to cope with the situation where the rechargeable battery has insufficient storage capacity due to insufficient solar energy or no light at night, it will automatically switch to the battery to take over the power supply, ensuring the continuous lighting of the light string, extending the continuous lighting time of the light string, and thus extending the service life.

[0010] Preferably, a battery cavity is formed in the box seat, and the rechargeable battery is embedded in the battery cavity for installation. The rechargeable battery is provided with an isolation plate, and the isolation plate is fixed to the battery cavity opening for sealing the rechargeable battery.

[0011] Through the above technical solution, the shape and size of the battery cavity are adapted to the rechargeable battery. The positive and negative poles of the rechargeable battery are aligned with the internal circuit and then embedded in the battery cavity to achieve electrical connection. The rechargeable battery has the ability to repeatedly store and discharge electricity. The isolation plate is adapted to the opening of the battery cavity. Since the rechargeable battery does not need to be replaced frequently, the isolation plate is fixed after covering the opening of the battery cavity to seal the rechargeable battery, preventing external impurities from invading the battery cavity, thereby ensuring the efficiency of the rechargeable battery and extending its service life.

[0012] Preferably, the solar panel is provided with a transparent protective layer, which is fixed to the box seat for fixing the solar panel, and the transparent protective layer is located on the side of the solar panel away from the bottom of the installation groove.

[0013] Through the above technical solution, after the solar panel is embedded in the installation groove, the transparent protective layer is fixed on the box seat. The transparent protective layer is crystalline and has a certain transparency, which facilitates the penetration of sunlight. The transparent protective layer is tightly combined with the solar panel to limit the solar panel from detaching from the installation groove, while preventing erosion from the external environment, thereby extending the service life of the solar panel and improving protection.

[0014] Preferably, a hinge portion and a positioning assembly are provided between the box cover and the box base, respectively. The hinge portion includes an extension portion provided on the box cover and a hinge column.

The positioning part 1 and the positioning part 2 cooperate to clamp the hinge column to realize the hinge of the box cover.

[0016] Through the above technical solution, when the box cover and the box base are close to each other, the hinge part contacts the positioning assembly, and the extension part in the hinge part extends toward the position of the positioning assembly. The positioning part one and the positioning part two are located on opposite sides along the hinge axis of the box cover, and the hinge column is embedded between the positioning part one and the positioning part two so that the hinge column provides a hinge axis.

[0017] Preferably, a fixing structure is provided between the box base and the box cover, and the fixing structure includes a buckle portion and a clamping protrusion, and the buckle portion and the clamping protrusion are respectively provided on the box base and the box cover in a one-to-one correspondence;

[0018] The buckle portion includes an elastic connection portion arranged on a corresponding component and a dial portion arranged on the elastic connection portion. The elastic connection portion is provided with a button hole. The elastic connection portion extends toward another component, and the snap-fit ​​protrusions are embedded in the button holes in a one-to-one correspondence.

[0019] Through the above technical solution, the buckle part is set on one of the components of the box base or the box cover, and the clamping protrusion is set on the other component. When the box cover and the box base are close to each other, the paddle part contacts the clamping protrusion so that the elastic connection part is deformed through the clamping protrusion. Based on the adaptation of the buckle hole of the elastic connection part and the clamping protrusion, the buckle hole moves its position to align with the clamping protrusion, and the clamping protrusion is embedded in the buckle hole to realize the relative fixation of the box base and the box cover, thereby further improving the installation stability of the grounding seat.

[0020] Preferably, the engaging protrusion has a guide surface, and the guide surface is inclined toward a side close to the buckling portion. When the buckling portion is engaged with the engaging protrusion, the end surface of the shift plate portion close to the guide surface is connected with the guide surface for guidance.

[0021] Through the above technical solution, when the buckle part is mated with the snap-fitting protrusion, the side of the snap-fitting protrusion with the guide surface faces the dial plate part, and the end face of the dial plate part close to the guide surface is adapted to the inclined direction of the guide surface. After the two end faces contact each other, the dial plate part passes along the guide surface and guides the mating of the snap-fitting protrusion, so that the buckle part and the snap-fitting protrusion are mated more quickly and accurately, thereby improving smoothness and thus improving efficiency.

[0022] Preferably, the box cover is provided with a mounting portion, the mounting portion is provided with a hanging hole, the inner wall of the hanging hole is provided with a positioning groove, and when the bolt passes through the hanging hole, the positioning groove and the bolt body are opposite to each other for embedding and positioning.

[0024] Preferably, the box cover is provided with a plug-in portion, the plug-in portion is provided with a slot, and the slot is used for plug-in installation.

[0025] Through the above technical solution, a plug-in component that is compatible with the slot is installed at the installation position. The slot opening is aligned with the plug-in component so that after the plug-in board is inserted along the slot, the end of the plug-in portion away from the box cover is bent and extended into the slot, so that the plug-in portion plays a limiting role on the plug-in component, thereby improving the stability of the installation.

[0026] Preferably, the box seat is provided with a sealing ring, which surrounds the upper end of the box seat and is tightly pressed between the box cover and the box seat.

[0027] Through the above technical solution, the sealing ring surrounds the upper end of the box seat and is fixed on the box seat. When the box cover is closed, it rests on the box seat. When the fixing structure is locked, the sealing ring is pressed tightly between the box cover and the box seat, reducing the gap between the box cover and the box seat, improving the airtightness of the box seat, and preventing rainwater from intruding into the box seat when the control box is installed outdoors, thereby improving safety in use.

[0028] Compared with the existing technology, this technical solution has the following outstanding and beneficial technical effects:
