The base unit 1 has a first battery module 101 and a photovoltaic module 102. The photovoltaic module 102 is electrically connected to the first battery module 101 and charges the first battery module 101 with solar energy. The lamp head unit 2 is detachably mounted on the base unit 1 and has a second battery module 201 and a light-emitting element 202. The light-emitting element 202 is electrically connected to the second battery module 201 and is powered by the first battery module 101.

[0036] In some embodiments of the present application, Figure 2 , 3 As shown in Figure 4, the bottom of the base unit 1 is the lower seat 103. The photovoltaic module is installed on the lower seat 103, which lifts the photovoltaic module off the ground. The upper end of the lower seat 103 is bolted to a vertically arranged positioning plate 104. There are four positioning plates 104, each corresponding to one side of the base unit 1. Adjacent positioning plates 104 are also connected by insert strips for positioning, thus connecting the positioning plates 104 into a whole in the height direction, improving the stability of the overall structure. The photovoltaic module is a prior art product. The photovoltaic panel in the photovoltaic module uses a flexible photovoltaic panel with shingled technology. The photovoltaic panel has two sides... Do not insert into the corresponding slot of the positioning plate 104. The positioning plate 104 has a vertically arranged support in the middle position. The support is used to support the middle of the photovoltaic panel, thereby further improving the deformation resistance of the panel structure. The positioning plate 104 is connected to the first partition 105, the second partition 106, and the upper seat 107 in sequence by bolts. The first battery module 101 is an existing product. The first battery module 101 is installed in the area formed by the first partition 105 and the upper seat 107. The controller of the photovoltaic module 102 is connected to the surface of the first battery module 101, and the photovoltaic module 102 charges the first battery module 101.

[0037] In some embodiments of the present application, Figure 2As shown, the base unit 1 also includes a wireless charging module 108. The wireless charging module 108 is an existing product and is located at the top of the base unit 1. The charging plate of the wireless charging module 108 is located in the middle of the upper surface of the upper body 107. The wireless charging module 108 is electrically connected to the first battery module 101 and is used to charge the second battery module 201.

The lower end of the lamp base 203 has a cavity for installing a second battery module 201. The second battery module 201 is an existing product. The power of the second battery module 201 is less than that of the first battery module 101, thereby reducing the size of the second battery module 201 and reducing the weight of the lamp holder unit 2. The lamp base 203 is equipped with a first drain outlet 205, and a light-emitting element 202 is provided in the middle of the lamp base 203. The light-emitting element 202 adopts... The LED light strip has a light-emitting element 202 in the center of the lamp holder 203. An outer frame 206 is arranged around the upper part of the lamp holder 203, with large through holes on its four sides to allow light emitted from the light-emitting element 202 to pass through. A first drain outlet 205 is located around the lower part of the outer frame 206. A lamp cover 204 is fixedly connected to the upper center of the base via a double-ended screw. The lamp cover 204 is positioned above the light-emitting element 202 and has a second drain outlet 207. The first and second drain outlets 205 and 207 facilitate the drainage of rainwater from the lamp cover 204 and the lamp holder 203.

[0040] In some embodiments of the present application, Figure 7 As shown, the lamp head unit 2 also includes a lamp cap 208, which covers the upper part of the light source 202 and is fitted around the lamp cover 204. The lamp cap 208 expands the rain-blocking range and further reduces the probability of rainwater entering the lamp holder 203.

[0041] In some embodiments of the present application, Figure 7 As shown, the lamp holder unit 2 also includes a lamp cover 209, which is transparent and covers the outer periphery of the light-emitting body 202. The lamp cover 209 is disposed between the base and the lamp cover 204. The lamp cover 209 improves the protection of the light-emitting body 202, thereby extending the service life of the product.

[0042] In some embodiments of the present application, Figure 7 As shown, the lamp head unit 2 also includes a handle 210, which is disposed at the upper end of the lamp head unit 2 and is rotatably connected to a groove disposed at the upper end of the lamp cover 204. By configuring the handle 210, it is convenient for the user to carry the lamp head unit 2 or to hang and fix the lamp head unit 2.

[0043] In some embodiments of the present application, Figure 7 As shown, the lamp holder unit 2 also includes a switch 211, which connects the light-emitting element 202 to the second battery module 201. The switch 211 controls the light-emitting element 202 to be turned on or off.

[0044] In some embodiments of the present application, Figure 2 , 8 As shown, the upper end of the base unit 1 is provided with four first positioning grooves 110, which are located at the four corners of the upper body 107. The lower end of the base unit 1 is provided with four first positioning protrusions 212, which are located at the four corners of the lower end of the lamp holder 203 and correspond one-to-one with the first positioning grooves 110. The first positioning protrusions 212 are inserted into the first positioning grooves 110 for positioning. The insertion positioning relationship enables the rapid positioning of the base unit 1 and the lamp holder unit 2. This application embodiment also provides another technical solution for the positioning structure of the base unit 1 and the lamp holder unit 2: the upper end of the base unit 1 is provided with a second positioning protrusion, and the lower end of the base unit 1 is provided with a second positioning groove. The second positioning protrusion is inserted into the second positioning groove for positioning.

[0045] In some embodiments of the present application, Figure 8As shown, a first magnetic block 213 is assembled in the first positioning protrusion 212. The first magnetic block 213 is used to magnetically position the base unit 1 and the lamp head unit 2, thereby improving the stability of the connection between the two units. Alternatively, the first magnetic block 213 can also be configured in the first positioning groove 110. When using a second positioning protrusion and a second positioning groove for insertion and positioning, a second magnetic block can also be configured in the second positioning protrusion or the second positioning groove. The second magnetic block is used to magnetically position the base unit 1 and the lamp head unit 2.

[0046] When in use, this portable outdoor lamp utilizes solar energy through the photovoltaic module 102 to continuously charge the first battery module 101, which in turn charges the second battery module 201, thus solving the problem of the lamp's battery life. Simultaneously, the base unit 1 and the lamp head unit 2 are designed as detachable, separate structures using plug-in and magnetic positioning, allowing them to be used separately. When the lamp head unit 2 is placed on the base unit 1, the base unit 1 not only charges the lamp head unit 2 but also serves as a height-enhancing structure, raising its position. When the base unit 1 and lamp head unit 2 are separated, the base unit 1 can wirelessly charge the user's device. Users can place the lamp head unit 2 in any location, greatly improving the ease of use of this outdoor lamp.
