Description

Technical Field

[0001] This utility model relates to the field of household appliances, and more specifically, to a base with a retractable charging cable and a table lamp with the base. Background Technology

[0002] Currently, most mainstream desk lamps on the market adopt a three-section structural design consisting of a power supply base, a support rod, and a lighting module. In terms of power supply, traditional desk lamps typically rely on an external AC power adapter to achieve a single lighting function. Existing products only focus on basic lighting needs and do not fully consider the multi-scenario power needs of users. For example, when users need to charge smart devices (such as laptops, mobile phones, and tablets) simultaneously, they must rely on additional power supply equipment. The need to charge multiple devices means users must occupy multiple charging ports simultaneously, which can easily lead to cable tangles, power strip clutter, and other safety hazards in confined spaces such as office desks, significantly reducing space utilization efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a base with a retractable charging cable, which can charge external smart terminals without the need for an external power strip, and can keep the cable neat.

[0004] A base with a retractable charging cable includes a base housing. Inside the base housing are a main circuit board, an output data cable, and a mounting base. The main circuit board is electrically connected to an input power source. The mounting base includes a winding reel for the output data cable to be wound. The winding reel is circumferentially rotatable and axially fixed inside the base housing. An elastic reset structure is provided between the winding reel and the output data cable. The base housing has an output hole. One end of the output data cable is electrically connected to the main circuit board, and the other end passes through the output hole.

[0005] By adopting the above technical solution, the input power supply powers the main circuit board, which in turn powers the output data line, which then powers the external smart terminal. The winding reel allows the output data line to be pulled out by the user, and when needed, it can be retracted into the base housing using the elastic reset structure and the winding reel.

[0006] Preferably, the mounting base includes a detachably fixed upper housing and a lower housing, with a receiving cavity formed between the upper housing and the lower housing, and the winding reel is disposed in the receiving cavity and is circumferentially rotatably and axially fixedly connected to the upper housing and / or the lower housing.

[0007] Preferably, the upper or lower housing is connected to a secondary circuit board, which is located within the receiving cavity. The secondary circuit board is electrically connected to the main circuit board, and the output data line is electrically connected to the secondary circuit board.

[0008] By adopting the above technical solution, the output data line is constrained within the receiving cavity. The output data line can extend out of the output hole or retract into the receiving cavity without causing the output data line to become tangled inside the base housing or detach from the winding disc, thus ensuring that the extension or retraction of the output data line is stable and reliable.

[0009] Preferably, the winding coil includes a planar portion, an open support portion, and a planar, incense-shaped elastic portion. The elastic portion is placed inside the open portion of the support portion, and the outer free end of the elastic portion is provided with an elastic structure. When the output data line is wound on the support portion, it abuts against the elastic structure.

[0010] Preferably, the support portion includes a first arc segment and a second arc segment, with a first gap and a second gap formed between the first arc segment and the second arc segment. The outer free end of the elastic portion extends out of the first gap and folds back through the first arc segment and the second gap into the opening of the support portion. The outer free end of the elastic portion is arranged in a protruding shape near the first gap and facing the output data line to form an elastic reset structure. The elastic reset structure is in contact with the output data line.

[0011] By adopting the above technical solution, the elastic part is stably and reliably placed in the opening of the support part, and will not be displaced when the output data line is extended or retracted. At the same time, the elastic reset structure enables the output data line to be quickly and stably retracted into the mounting base.

[0012] Preferably, the planar portion is provided with a through hole, and the second arc segment is provided with a third arc segment on the side opposite to the elastic portion. The second arc segment and the third arc segment are located on both sides of the through hole, and one end of the output data line is placed between the second arc segment and the third arc segment, and passes through the through hole to be electrically connected to the sub-circuit board.

[0013] By adopting the above technical solution, when the output data line is almost completely pulled out of the output hole, if the end of the output data line located inside the base housing is not constrained, the output data line may become misaligned or messy when it is retracted. The setting of the second arc segment and the third arc segment can constrain the end of the output data line located inside the base housing, ensuring that the output data line can remain neat and orderly when it is retracted into the base housing.

[0014] Preferably, at least two mounting bases are provided, and each mounting base is provided with an output data line, with the number of output holes, mounting bases, and output data lines corresponding to each other.

[0015] By adopting the above technical solutions, different output data cables can have different connectors, such as USB connectors, Type-C connectors, and Lightning connectors, to facilitate charging of smart terminals with different interfaces and improve the practicality of the dock.

[0016] Preferably, the surface of the base housing is provided with a snap-fit ​​portion for embedding one end of the output data cable that extends out of the output hole.

[0017] By adopting the above technical solution, when the output data cable is not needed, the end of the output data cable exposed outside the base housing can be embedded in the snap-fit ​​part, which can protect the output data cable on the one hand and reduce the space occupied by the base on the other hand.

[0018] Preferably, the base housing is further provided with a wireless charging module for wirelessly charging an external smart terminal. The base housing has a housing through hole, and the wireless charging module is located between the base housing and the mounting base. The wireless charging module includes a wireless charging housing and a wireless charging circuit unit located inside the wireless charging housing. The wireless charging housing is embedded in the housing through hole.

[0019] By adopting the above technical solution, a wireless charging module is added to the base shell, which can wirelessly charge smart terminals such as mobile phones, smartwatches, and smart rings. One base can have multiple charging methods and can charge different terminals at the same time, further improving the practicality of the base.

[0020] The purpose of this utility model is to provide a desk lamp with any of the above-mentioned bases with retractable charging cables, which can charge external smart terminals without the need for external power strips, and can keep the cables neat, thus improving the practicality of the desk lamp.

[0021] A table lamp includes a lamp head, a connecting rod, and a base, wherein the base is as described above.

[0022] By adopting the above technical solution, the practicality of the desk lamp is greatly improved, and it can also provide power to other smart terminals while the desk lamp is in use. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-12 The present invention will be further described below.

[0037] Example 1

[0038] like Figure 1-8As shown, a base with a retractable charging cable includes a base housing 1, which includes an upper base housing and a lower base housing. The upper and lower base housings form a base cavity, and a main circuit board 2, an output data cable 3, and a mounting base 4 are disposed inside the base cavity.

[0039] Mounting base 4 includes an upper housing 41, a lower housing 42, and a winding reel 43. The upper housing 41 and the lower housing 42 are detachably and fixedly connected (here, detachable and fixed connection refers to a connection in which the upper housing 41 and the lower housing 42 are fixed in the connected state, but can be detached and separated, such as by bolt connection, snap connection, or plug-in connection).

[0040] A receiving cavity is formed between the upper housing 41 and the lower housing 42. The winding reel 43 is disposed within the receiving cavity. A secondary circuit board 44 is also provided between the winding reel 43 and the upper housing 41, or between the winding reel 43 and the lower housing 42. The main circuit board 2 is electrically connected to the input power supply, the secondary circuit board 44 is electrically connected to the main circuit board 2, and the output data line 3 is electrically connected to the secondary circuit board 44. It should be noted that the main circuit board 2 and the secondary circuit board 44 can actually be a single circuit board, or the output data line 3 can be directly electrically connected to the main circuit board 2. However, if the two circuit boards are separate, the secondary circuit board 44 can be built into the mounting base 4, facilitating the electrical connection between the output data line 3 and the secondary circuit board 44. Furthermore, if multiple mounting bases 4 are provided, a problem in the circuit of one mounting base 4 will not affect the electrical connection between other mounting bases 4 and other data lines.

[0041] It should be noted that the input power source here can be an external power source, or a battery 45 electrically connected to the main circuit board 2 and installed inside the base housing 1. The battery 45 obtains power from the outside and then provides power to the main circuit board 2 and / or the sub-circuit board 44. Preferably, the base is provided with a power input line electrically connected to the external power source. At the same time, the battery 45 is also installed inside the base housing 1, so that the base can be used to power external smart terminals even when there is an external power outage. The base housing 1 is provided with a charging port 11 electrically connected to the battery 45. The charging port 11 can be an input interface for the battery 45, an output interface for the battery 45 to charge external terminals, or both.

[0042] The winding reel 43 includes a flat portion 431, an open support portion 432, and a flat, incense-shaped elastic portion 433. The flat portion 431 provides bottom support for the output data cable 3 after it is wound into coils, the support portion 432 provides central support for the output data cable 3 during winding, and the elastic portion 433 mainly provides a restoring force to the output data cable 3 when it is retracted into the mounting base 4.

[0043] The winding reel 43 is disposed within the receiving cavity and is circumferentially rotatably and axially fixedly connected to the upper housing 41 and / or the lower housing 42. Specifically, a connecting shaft 46 can be provided between the winding reel 43 and the upper housing 41 and / or the lower housing 42. The winding reel 43 is fitted onto the connecting shaft 46 with a clearance fit or an overfit, and the connecting shaft 46 is fixedly connected to the upper housing 41 and the lower housing 42. It should be noted that a connecting bearing can also be circumferentially rotatably and axially fixedly fitted onto the surface of the connecting shaft 46, and the connecting shaft 46 is fixedly connected between the upper housing 41 and / or the lower housing 42. The bearing is fixedly connected to the winding reel 43. To save costs, the bearing can also be omitted.

[0044] The support portion 432 includes a first arc-shaped segment 4321 and a second arc-shaped segment 4322. A first gap 4323 and a second gap 4324 are formed between the first arc-shaped segment 4321 and the second arc-shaped segment 4322. The outer free end of the elastic portion 433 extends out of the first gap 4323 and is folded back into the opening of the support portion 432 via the first arc-shaped segment 4321 and the second gap 4324. The elastic portion 433 is placed in the opening of the support portion 432, and the outer free end of the elastic portion 433 is provided with an elastic structure. When the output data line 3 is wound around the support portion 432, it is in contact with the elastic structure. Preferably, the portion of the elastic part 433 folded back into the opening of the support part 432 is preferably fitted against the inner wall of the first arc-shaped segment 4321. This ensures that even with frequent and prolonged pulling of the output data line 3, the elastic part 433 remains stably and reliably within the support part 432 without displacement. The outer free end of the elastic part 433 protrudes near the first gap 4323 and towards the output data line 3, forming an elastic reset structure 4331. The elastic reset structure 4331 is in contact with the output data line 3. It should be noted that the elastic reset structure 4331 can be the entire outer free end of the elastic part 433. To balance the installation stability of the elastic part 433 and its reliable reset function for the output data line 3, it is preferable that a portion of the outer free end of the elastic part 433 is fitted against the first arc-shaped segment 4321, and a portion forms the elastic reset structure 4331.

[0045] The base housing 1 is equipped with a charging port 12. One end of the output data cable 3 is electrically connected to the main circuit board 2 via a secondary circuit board 44. The cable is wound around the open support part 432 and partially contacts the elastic reset structure 4331 of the elastic part 433. The other end extends out of the charging port 12 for the user to pull out and for charging the smart terminal. That is, the input power supplies the main circuit board 2, which in turn supplies power to the output data cable 3, which then supplies power to the external smart terminal. The winding reel 43 allows the output data cable 3 to be pulled out by the user and retracted into the base housing 1 when needed using the elastic reset structure 4331 and the winding reel 43.

[0046] The base housing 1 has a snap-fit ​​part 13 on its surface for embedding one end of the output data line 3 that extends out of the charging port 12. When the output data line 3 is not needed, the end of the output data line 3 exposed outside the base housing 1 can be embedded in the snap-fit ​​part 13, which can protect the output data line 3 and reduce the space occupied by the base.

[0047] The planar portion 431 is provided with a through hole 4311. The second arc-shaped segment 4322 is provided with a third arc-shaped segment 4325 on the side opposite to the elastic portion 433. The second arc-shaped segment 4322 and the third arc-shaped segment 4325 are located on both sides of the through hole 4311. One end of the output data line 3 is placed between the second arc-shaped segment 4322 and the third arc-shaped segment 4325, and passes through the through hole 4311 to be electrically connected to the sub-circuit board 44. Preferably, the second arc-shaped segment 4322 and the third arc-shaped segment 4325 are fixedly connected at one end of the through hole 4311, and a gap is formed between the other end for the output data line 3 to be installed. When the output data cable 3 is almost completely pulled out of the charging port 12, if the end of the output data cable 3 located inside the base housing 1 is not constrained, the output data cable 3 may become misaligned or disordered when it is retracted. The setting of the second arc segment 4322 and the third arc segment 4325 can constrain the end of the output data cable 3 located inside the base housing 1, ensuring that the output data cable 3 can remain neat and orderly when it is retracted into the base housing 1.

[0048] Example 2

[0049] Unlike Embodiment 1, there are at least two mounting bases 4, each with an output data cable 3. The number of charging ports 12, mounting bases 4, and output data cables 3 are all in one correspondence. Different output data cables 3 can have different connectors, such as USB connectors, Type-C connectors, and Lightning connectors, to facilitate charging of smart terminals with different interfaces and improve the practicality of the base.

[0050] Example 3

[0051] like Figure 9-10 Unlike Embodiment 1, the base housing has a housing through hole, and a wireless charging module for wirelessly charging external smart terminals (such as mobile phones, smartwatches, smart rings and other electronic products) is embedded in the housing through hole. The wireless charging module includes a wireless charging housing and a wireless charging circuit unit located in the wireless charging housing. The wireless charging housing is embedded in the housing through hole, and the wireless charging housing can be flush with, lower than or higher than the surface of the base housing.

[0052] It should be noted that wireless charging is a relatively mature technology. The wireless charging module can be implemented using existing wireless charging structures and circuits on the market. The core point of this invention is to integrate the wireless charging module into the base, rather than to innovate the wireless charging module itself. Therefore, the specific structure and circuit of the wireless charging module will not be described in detail here. Mature wireless charging structures and corresponding wireless charging circuits on the market can be used.

[0053] Example 4

[0054] As shown in Figures 11-12, a table lamp includes a lamp head 5, a connecting rod 6, and a base, wherein the base is the base described in Embodiment 1, Embodiment 2, or Embodiment 3.

[0055] By adopting the above technical solutions, the practicality of the desk lamp is greatly improved, allowing it to provide power to other smart devices while in use. A base with any of the aforementioned retractable charging cables can charge external smart devices without the need for an external power strip, while also keeping cables neat and tidy, further enhancing the desk lamp's usability.

[0056] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model.
