[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Figure 1-7 As shown, the split-type quick-connect rechargeable desk lamp includes a base 1 and a lamp body 2. The lamp body 2 is detachably and fixedly connected to the base 1. The base 1 is provided with a slot 101 and a conductive pin 102. The slot 101 is open upward for the lower end of the lamp body 2 to be inserted. The conductive pin 102 is located at the bottom of the slot 101. The lamp body 2 is provided with a circuit board 201, a light source 202 and a battery 203. The battery 203 is electrically connected to the circuit board 201 and the light source 202 respectively. The circuit board 201 is electrically connected to the light source 202. The circuit board 201 is a bare copper PCB without a solder mask layer. The conductive pin 102 is made of copper. At least part of the circuit board 201 is exposed at the end of the lamp body 2 that is inserted into the slot 101. When the lamp body 2 is inserted into the slot 101, the conductive pin 102 abuts against the circuit board 201 and conducts electricity. The base 1 is provided with a power cord 103 that is electrically connected to the conductive pin 102. The power cord 103 is used to connect to the mains power. When the lamp body 2 is inserted into the slot 101 and the conductive pin 102 abuts against the circuit board 201, if the power cord 103 is connected to the mains power, the mains power charges the storage battery 203 and supplies power to the light source 202. If the power cord 103 is disconnected from the mains power, the light source 202 is powered by the storage battery 203.

[0027] This utility model provides a detachable, quick-connect rechargeable desk lamp to solve the problem of existing desk lamps that rely on a power cord to connect to the mains power supply to power the light source, thus limiting the lamp's placement. The main improvement is achieved by detachably connecting the base 1 and the lamp body 2. The base 1 has a slot 101 and conductive pins 102, while the lamp body 2 has a circuit board 201 and a battery 203. The lamp body 2 is inserted into the slot 101, allowing the conductive pins 102 to contact the circuit board 201 for conductivity. When the power cord 103 is connected to the mains power supply, the mains power charges the battery 203 and powers the light source 202. When the power cord 103 is disconnected from the mains power supply, the battery 203 powers the light source 202. This allows the lamp body 2 to be used detached from the base 1, enabling flexible placement. Furthermore, by configuring the circuit board 201 as a bare copper PCB without solder mask, the conductive pins 102 immediately contact the circuit board 201 when the lamp body 2 is inserted into the slot 101, allowing for flexible contact and quick operation.

[0028] In this embodiment of the invention, a positioning block 104 protrudes from the bottom of the slot 101, and a conductive pin 102 is disposed on the positioning block 104. A positioning groove 204 is recessed at one end of the lamp body 2 that is inserted into the slot 101. The circuit board 201 is disposed on the bottom of the positioning groove 204. The positioning block 104 is inserted into the positioning groove 204 when the lamp body 2 is inserted into the slot 101, and the conductive pin 102 abuts against the circuit board 201 when the positioning block 104 is inserted into the positioning groove 204. This arrangement, by configuring the positioning block 104 at the bottom of the slot 101 and the positioning groove 204 at the lower end of the lamp body 2, ensures stable assembly of the base 1 and the lamp body 2, stable assembly of the circuit board 201 with the lamp body 2, and good contact between the circuit board 201 and the conductive pin 102.

[0029] In this embodiment of the invention, the positioning block 104 and the slot sidewall of the slot 101 are spaced apart to form a limiting gap for the insertion of the lamp body 2 (not shown in the figure), and the limiting gap extends circumferentially around the positioning block 104. This arrangement, by configuring the positioning block 104 to form a limiting gap with the slot sidewall of the slot 101 to form a limiting gap for the insertion of the lamp body 2, ensures stable assembly of the base 1 and the lamp body 2.

[0030] In this embodiment of the invention, the base 1 has a receiving cavity 105, and the conductive needle 102 is partially housed within the receiving cavity 105 and partially protrudes from the bottom of the slot 101. The conductive needle 102 can move up and down relative to the base 1 and abuts against the circuit board 201 when the lamp body 2 is inserted into the slot 101. This configuration, by arranging the conductive needle 102 to move up and down relative to the base 1 and abut against the circuit board 201 when the lamp body 2 is inserted into the slot 101, ensures good contact and excellent conductivity between the conductive needle 102 and the circuit board 201 when the lamp body 2 is inserted into the slot 101.

[0031] In this embodiment of the invention, an elastic element 106 is provided in the accommodating cavity 105, and the conductive needle 102 is driven to move upward by the elastic element 106. This arrangement, by configuring the elastic element 106 within the accommodating cavity 105 to drive the conductive needle 102 to move upward, ensures good contact between the conductive needle 102 and the circuit board 201 and excellent conductivity when the lamp body 2 is inserted into the slot 101.

[0032] In this embodiment of the invention, a limiting plate 107 is provided inside the receiving cavity 105. The limiting plate 107 restricts the conductive needle 102 from completely entering the receiving cavity 105 when it moves in. This arrangement, by configuring the limiting plate 107 inside the receiving cavity 105 to restrict the conductive needle 102 from completely entering the receiving cavity 105, prevents the conductive needle 102 from being unable to move upwards and reset after being completely inserted into the receiving cavity 105.

[0033] In this embodiment of the invention, the conductive needle 102 has an abutment portion 108 and a limiting portion 109. The abutment portion 108 is disposed on the upper side of the limiting portion 109 and cooperates with the limiting portion 109 to form a limiting shoulder (not shown in the figure). The limiting plate 107 is provided with a limiting hole 110 for the limiting portion 109 to be inserted. The elastic member 106 passes through the limiting portion 109 and abuts against the abutment portion 108 and the limiting plate 107 respectively. By configuring the conductive needle 102 with the abutment portion 108 and the limiting portion 109 forming the limiting shoulder on the upper and lower sides, the elastic member 106 is disposed on the limiting portion 109 and abuts against the abutment portion 108 and the limiting plate 107 respectively, and the limiting plate 107 is provided with a limiting hole 110 for the limiting portion 109 to be inserted, the conductive needle 102 is stably assembled with the base 1 and moves smoothly.

[0034] In this embodiment of the invention, the lamp body 2 is provided with an assembly cavity 205 for accommodating the battery 203, and the bottom of the positioning groove 204 is provided with a lead hole 206 communicating with the assembly cavity 205. The circuit board 201 is attached to the bottom of the positioning groove 204 and partially extends into the assembly cavity 205 through the lead hole 206. This arrangement, by configuring the assembly cavity 205 for accommodating the battery 203 on the lamp body 2, and providing the lead hole 206 communicating with the assembly cavity 205 at the bottom of the positioning groove 204, and by having the circuit board 201 attached to the bottom of the positioning groove 204 and partially extending into the assembly cavity 205 through the lead hole 206, ensures stable assembly of the circuit board 201 and facilitates the connection of the circuit board 201 with the battery 203 leads.
