Description

Technology sector

[0001] The present invention relates to the technical field of charging devices, in particular a charging base. Technical background

[0002] As time has progressed, electrical energy has been used in various fields, such as in portable electronic devices and other rechargeable electronic devices like smartphones, tablets, and aroma lamps, which have become indispensable tools in people's daily lives and work. These devices are typically powered by built-in batteries and therefore require frequent recharging. To meet the need to charge multiple devices simultaneously, various charging bases are available on the market.

[0003] Currently, most charging bases use a single charging plug or wireless charging pad design, meaning only one electronic device can be charged at a time. If a user owns multiple electronic devices, they often have to search for different chargers or charge the devices one after the other. This not only occupies multiple power outlets and creates a tangle of cables on the desk, but it also results in low charging efficiency and wastes the user's time.

[0004] Therefore, a charging base is being designed to solve the aforementioned technical problems. Content of the utility model

[0005] The technical problem solved by this utility model is to overcome the disadvantages of the prior art. A loading base is provided.

[0007] The planned improvement is that the power supply unit is a printed circuit board assembly (PCBA), each of the charging plugs is soldered onto the PCB assembly, and one end of the cable harness is soldered to the PCB assembly.

[0008] The planned improvement is that the power supply unit is a conductor wire, each of the charging plugs is soldered to the conductor wire, and one end of the wiring harness is soldered to the conductor wire.

[0014] In the following, a loading base according to the invention (utility model) is explained in more detail with reference to the accompanying drawings.

[0015] With reference to the Fig.1-10 comprises a charging base, a power supply unit, a housing 2, a mains plug 3, and a charging plug 4. The power supply unit is located in the housing 2. Several charging plugs 4 are provided at the upper end of the housing 2. The upper part of the charging plugs 4 protrudes from the housing 2 to connect directly to the electronic devices to be charged. The lower part of the charging plugs 4 extends into the housing 2. Each charging plug 4 is soldered to the power supply unit. A cable harness 5 is soldered to the rear end of the mains plug 3. The other end of the cable harness 5 extends from one end of the housing 2 into the housing 2, and the end of the cable harness 5 protruding into the housing 2 is soldered to the power supply unit.In this way, the current can flow from the mains plug 3 via the cable harness 5 and then via the power supply unit to the individual charging plugs 4, in order to realize the energy transfer from the external power source to the charging plugs 4.

[0016] In detail: The power plug 3 can be a USB plug, a two-pin plug, a three-pin plug, etc.

[0017] If the power connector 3 is designed as a USB connector, the USB connector can be connected to the power supply unit via the cable harness 5; alternatively, the USB connector can be installed directly in the cable entry 8 on the upper housing 6, with the USB connector soldered directly to the power supply unit. In this way, the cable harness 5 can be eliminated, and the charging base can be plugged directly into a USB power source via the USB connector.

[0018] The charging plugs can be designed as Type-C plugs, Micro-B plugs, etc. This allows the charging base to be used for a wider range of electronic devices.

[0019] Example 1: The power supply unit is a printed circuit board assembly (PCBA) 1. Each of the charging connectors 4 is soldered to the PCBA 1, and one end of the cable harness 5 is soldered to the PCBA 1. The voltage conversion and distribution of current and voltage to the individual charging connectors 4 is carried out via the PCBA 1.

[0020] When using a PCBA 1, the mains connector 3 can be designed as a USB connector, a two-pin connector, a three-pin connector, etc.

[0021] Example 2: The power supply unit is a conductor wire 13. Each of the charging plugs 4 is soldered to the conductor wire 13, and one end of the cable harness 5 is soldered to the conductor wire 13.

[0022] When using a conductor wire 13, the mains plug 3 is designed as a USB plug, so that the supply voltage passed through the USB plug is relatively low, which is sufficient to directly charge other electronic devices such as wax melting lamps without causing damage to the electronic devices due to excessive voltage.

[0023] The housing 2 comprises an upper housing 6 and a lower housing 7 connected to the upper housing 6. To facilitate the insertion of the cable harness 5, a cable gland 8 is provided at one end of the upper housing 6. One end of the cable harness 5 is inserted from the cable gland 8 into the upper housing 6.

[0024] Several grooves 9 are provided at the upper end of the upper housing 6. The charging plugs 4 extend from the upper housing 6 through the corresponding grooves 9.

[0025] The number of slots (9) corresponds to the 4 charging plugs, ensuring that each charging plug fits precisely through, thus facilitating the insertion and removal of electronic devices. The number of slots (9) and charging plugs (4) can be 4, 6, 8, etc.

[0026] A partition 10 is provided on each side of the grooves 9 at the top end of the upper housing 6, so that several devices can be charged simultaneously without interfering with each other, which increases the stability and safety of the application.

[0027] Several internally threaded tubes 11 are provided on the inner upper wall of the upper housing 6. Several round tubes 12 are provided on the lower housing 7, with the inner bores of the round tubes 12 connected to the outer surface of the lower housing 7. Screws are arranged in the round tubes 12. After connecting the upper housing 6 to the lower housing 7, the screws are connected to the internally threaded tubes 11 to fasten the upper housing 6 and the lower housing 7.

[0028] Regarding the specific implementation of the present utility model: Example 1: If the power supply unit is a PCBA 1: When using this charging base, the user simply plugs the power adapter 3 into a wall outlet or USB port to power the base. The user can then connect multiple electronic devices (e.g., Bluetooth headphones, smartwatches, game controllers, aroma lamps, etc.) directly to the corresponding charging adapters 4 and charge them simultaneously, without having to find a separate charger and outlet for each device. This significantly simplifies the charging process, saves charging time, and increases charging efficiency. Example 2: If the power supply unit is a conductor wire 13, wherein the mains plug 3 is designed as a USB plug: When using this charging base, the user simply plugs the USB power adapter 3 into a USB port to power the base. The user can then connect multiple electronic devices (e.g., Bluetooth headphones, smartwatches, game controllers, aroma lamps, etc.) directly to the corresponding charging adapters 4 and charge them simultaneously, without having to find a separate charger and power outlet for each device. This significantly simplifies the charging process, saves charging time, and increases charging efficiency. In the specific implementation of the present invention:
