Description

Technical Field

[0001] This utility model relates to the field of charging technology, and in particular to a charging structure for charging electronic products that can be used in smart home devices, and a smart home device using the charging structure. Background Technology

[0002] With the development of technology, people are carrying more and more personal electronic products, such as smartphones, game consoles, and personal digital assistants (PADs). Due to usage habits, when using smart toilets, massage chairs, mahjong tables, or other smart home devices, people often use electronic products to read news, listen to music, watch videos, play games, chat, etc. However, electronic products are prone to running out of power during use.

[0003] Based on this, some structures with built-in charging functions have emerged, such as the "Electronic Toilet Seat with USB Interface" disclosed in Chinese Patent 201620926283.7 and the "Smart Toilet Seat with USB Charging Interface" disclosed in 201821617883.0, both of which require a USB charging cable for connection and charging. However, while meeting charging needs, these charging structures bring new problems during use: on the one hand, people often forget to carry the charging cable, rendering the device unusable; even if they remember, storing it is inconvenient. On the other hand, water leaked during use of the smart toilet or showering can easily enter the USB socket, affecting the use of electronic products. Another common way to conveniently charge electronic products anytime is to connect a short USB charging cable to a power bank, the structure of which can be seen in [reference needed]. Figure 1 The USB charging cable 1' can be folded away on the surface of the casing 2' when not in use. It is then unfolded to charge the electronic product 3' when needed. This type of product can be found in TWD Patent No. 151460. Although the charging cable is connected to the power bank, this method uses a very short USB charging cable, which is almost flush against the side of the electronic product during charging. This makes it difficult for the user to operate the product properly, causing significant inconvenience. Furthermore, the power bank is inconvenient to carry and may be forgotten. Summary of the Invention

[0004] The first technical problem to be solved by this utility model is to provide a charging structure that is compatible with smart home devices, so that consumers can conveniently charge electronic products without having to carry a separate charging cable or power bank when using smart home devices, without affecting the use of electronic products, making it comfortable and convenient to use.

[0005] The technical solution adopted by this utility model to solve the first technical problem is as follows: the charging structure that can be used for smart home devices includes a housing, characterized in that: it also includes a pull-out charging cable disposed inside the housing, the inner end of the charging cable is connected to a control circuit board, and the outer end of the charging cable is connected to a charging plug.

[0006] To accommodate the charging cable and charging socket, the housing preferably has a first chamber for accommodating the charging cable and a second chamber for accommodating the charging plug, which can be opened. With the second chamber open, the user can pull out the charging plug to perform a charging operation. The first and second chambers can be separated by a partition, thus having a clear boundary. Alternatively, they can be without a clear boundary, for example, separated by only a few posts or protrusions. The first and second chambers can also be interconnected without a boundary. Here, the distinction is made only in the area within the housing where the charging cable and charging plug are located, to illustrate that there are two distinct areas within the housing for accommodating the charging cable and charging plug respectively.

[0007] To allow the second chamber to be opened or closed, a movable baffle is preferably included. This baffle can close or open the second chamber to enclose the charging plug within or pull it out from the second chamber. When the baffle closes the second chamber, it blocks the flow of gas or liquid between the second chamber and the external space, making the second chamber an independent space isolated from the outside. Therefore, the charging plug enclosed within the second chamber is protected from the effects of a humid environment.

[0008] To enable the baffle to open or close the second chamber, preferably, a pull-out plate that can slide within the second chamber is also included. The baffle is located at the outer end of the pull-out plate, and the charging plug is constrained on the pull-out plate. This design allows the baffle to open or close the second chamber by sliding along with the pull-out plate, and the charging plug can be constrained on the pull-out plate and pulled out of the second chamber together, thus facilitating the user to remove the charging plug and charge the product.

[0009] To facilitate the opening and closing of the second chamber, the second chamber is preferably equipped with a self-locking switch for locking or unlocking the pull-out plate when it is pressed. When the baffle is in the closed position, the pull-out plate is locked by the self-locking switch, which is configured to release the lock by pressing the pull-out plate. When the pull-out plate is unlocked, the second chamber can be opened by sliding along with the baffle. When the baffle slides back to the closed position, the pull-out plate is locked again by the self-locking switch.

[0010] To facilitate user access to the charging plug, preferably, the pull-out panel has edges on both sides extending along its sliding direction and protruding upwards, with at least one edge having a notch. Having two edges primarily serves the following functions: first, the edges on both sides facilitate sliding; second, the two edges also strengthen the structural connection between the baffle and the pull-out panel; third, the two edges facilitate user gripping and sliding the pull-out panel. However, a simple edge structure would make it inconvenient for the user to access the charging plug, while the notch allows the user's fingers to pass through and access the charging plug, eliminating the negative impact of the edge.

[0011] To enable the pull-out panel to slide within the second chamber, preferably, a guide rail protrudes from the bottom of the pull-out panel, and a guide portion is provided on the bottom wall corresponding to the second chamber to allow the guide rail to slide. A limiting member is also provided on the bottom wall to limit the outward sliding of the pull-out panel. The guide rail and guide portion cooperate with each other and with the aforementioned edge, ensuring that the pull-out panel can only slide along the guide portion. This allows the baffle to accurately open or close the second chamber, while the limiting member prevents the pull-out panel from detaching from the second chamber during outward sliding.

[0012] To facilitate the sliding of the pull-out panel, preferably, an elastic element is provided in the second chamber, with one end of the elastic element abutting against the second chamber and the other end abutting against the pull-out panel. This elastic element can be a spring, sheet, airbag, push rod, or other elastic component, allowing the pull-out panel to slide a certain distance outward when the self-locking switch is released, making it easier for the user to access the charging plug.

[0013] In order to achieve the function of opening or closing the second chamber with a relatively simple structure, the baffle may be a sliding plate or a flip-up cover that is disposed on the top of the second chamber and can slide horizontally.

[0014] To enable the charging cable to be pulled out and stored, preferably, a cable winder is provided in the first chamber. The cable winder includes a storage shell and a cable reel located inside the storage shell. The charging cable is wound around the cable reel, and the periphery of the storage shell has openings for the inner and outer ends of the charging cable to extend out. The cable reel can rotate clockwise or counterclockwise within the storage shell, allowing the charging cable to be pulled out for use or wound back into the storage shell. Therefore, by providing a cable winder, the limitation on the length of the charging cable can be alleviated to a certain extent, allowing the charging structure to be equipped with a charging cable of at least 1m in length, thereby improving the comfort and convenience for users when using the charging structure.

[0015] To restrict the movement of the charging plug, preferably, the second chamber is provided with a limiting seat that can limit the movement of the charging plug. When the second chamber is open, the user can pull the charging plug out from the limiting seat to perform the charging operation. The limiting seat serves to keep the charging plug in a preset position for easy access by the user. Furthermore, if the limiting seat is provided on the aforementioned pull-out plate, it also allows the charging plug to slide outward along with the pull-out plate to the outside of the second chamber when the pull-out plate and baffle slide outward, thus giving the pull-out plate a "dual-purpose" function.

[0016] To prevent jamming when pulling out the charging plug, preferably, the charging cable includes a first section wound on the reel and a second section exposed outside the reel, with a stop portion at the end of the second section that abuts against the corresponding opening of the reel; when the second chamber is closed, a preset chamber for accommodating the second section is provided between the limiting seat of the second chamber and the reel. This preset chamber accommodates the second section, allowing the previously reserved second section to move with the pull-out plate as it slides outwards, preventing the pull-out plate from being blocked by the reel; the stop portion prevents the second section from being wound into the reel as well.

[0017] To protect the control circuit board, preferably, the housing has a third chamber inside to house the control circuit board and electronic components. This third chamber can be clearly separated from the first and second chambers by a partition; however, there may be no clear boundary, for example, separated only by a few baffles or protrusions. The third chamber and the first and second chambers may be interconnected without a boundary. Here, the division is based solely on the area within the housing where the control circuit board is located, to illustrate that there is an area inside the housing that houses the control circuit board.

[0018] The second technical problem solved by this utility model is to provide a smart home device equipped with the aforementioned charging structure, addressing the current state of the technology. The smart home device provided by this utility model includes a main body and a power supply circuit. Its characteristic is that the main body is provided with the charging structure as defined above, and the charging structure is electrically coupled to the power supply circuit. Smart home devices require the circuit structure to be connected to a power source such as a socket in the room to function. Therefore, the circuit structure used for power supply allows the charging structure to charge electronic products. Furthermore, placing the charging structure within the main body of the smart home device protects the charging structure, further preventing issues such as humidity affecting usability.

[0019] Compared with the prior art, the advantages of this utility model are:

[0020] 1. This charging structure is compatible with smart home devices, allowing consumers to conveniently charge electronic products without having to carry additional charging cables or power banks, without affecting the use of electronic products; it is comfortable and convenient to use.

[0021] 2. The casing protects the charging plug, eliminating the need to carry a separate charging cable, and is also moisture-proof, waterproof, and easy to store after charging. Attached Figure Description

[0044] The present invention will be further described in detail below with reference to specific embodiments.

[0045] Example 1

[0046] like Figures 2-7 The image shown is a preferred embodiment of this utility model. (As shown...) Figures 2-4As shown, the charging structure in this embodiment includes a housing 1, which is divided into at least two chambers by a partition 10: a first chamber 11 and a second chamber 12. The partition 10 has at least one cable guide 101. The first chamber 11 is used to house a retractable charging cable 2. When in use, the charging cable 2 can be pulled out; when not in use, it can be retracted and wound inside the housing. The inner end 21 of the charging cable 2 is electrically coupled to a control circuit board 3, and the outer end 22 of the charging cable 2 passes through the cable guide 101 into the second chamber 12 and is connected to a charging plug 23 that can be connected to an electronic device. When the second chamber 12 is open, the user can pull out the charging plug 23 to perform a charging operation. The charging cable 2 is disposed in the first chamber 11 and is electrically coupled to the control circuit board 3. The housing 1 has a third chamber 31 inside which the control circuit board 3 and electronic components are housed. The control circuit board 3 can connect to smart home devices via a power supply cable such as an 8P cable, and converts a DC input of 12V to 36V into an output of 5V to 12V and 1.5A to 2.4A. However, the power supply cable is not limited to 8P, and similarly, the output range is not limited to 5V to 12V and 1.5A to 2.4A. Therefore, users do not need to carry a separate charging cable 2 to charge electronic products, which is more convenient. The second chamber 12 can only be opened by the user to pull out the charging plug 23 to perform the charging operation. That is, when the second chamber 12 is closed, it is isolated from the external environment, thus protecting the charging plug 23. In addition to eliminating the need to carry a separate charging cable 2, it can also prevent the use from being affected by the humidity of the environment. This makes the charging structure suitable not only for smart home devices located in dry environments, such as smart bedside tables, smart desks, and automatic mahjong tables, but also for smart home devices located in humid environments, such as smart toilets. In addition, it should be noted that the charging plug 23 in this embodiment has two interfaces, one of which is a Type-C interface and the other is a Lightning interface. The two interfaces can be selected to prevent overload. In addition, the charging plug 23 can also be configured with other numbers or types of interfaces according to actual needs.

[0047] Considering factors such as comfort and convenience during use, a cable reel 18 is also provided in the first chamber 11. (See attached image) Figure 5The cable reel 18 includes a housing 181, a cable reel 182 located inside the housing 181, and a charging cable 2 wound on the cable reel 182. The housing 181 has openings 183 on its periphery for the inner end 21 and the outer end 22 of the charging cable 2 to extend out. The cable reel 182 can rotate clockwise or counterclockwise within the housing 181, allowing the charging cable 2 to be pulled out for use or wound back into the housing 181. The principle of how the cable reel 182 winds up the charging cable 2 is not detailed internally, as it is a conventional structure, similar to a cable reel for a mouse. Therefore, by including the cable reel 18, the limitation on the length of the charging cable 2 can be alleviated to some extent, allowing the charging structure to accommodate a charging cable 2 at least 1 meter in length, thereby improving the user's comfort and convenience when using the charging structure.

[0048] Regarding the structure for opening and closing the second chamber 12, such as Figures 3-4 As shown, the second chamber 12 includes an opening 13 opposite to the partition 10 and a baffle 14 that can cover the opening 13. When the baffle 14 is closed, the charging plug 23 can be sealed inside the second chamber 12. When the baffle 14 covers the opening 13, it blocks the flow of gas or liquid between the second chamber 12 and the external space, making the second chamber 12 an independent space isolated from the external space. Therefore, the charging plug 23 sealed inside the second chamber 12 can be protected from the effects of a humid environment. Furthermore, opening or closing the second chamber 12 by using the baffle 14 also takes into account that the structure meets the usage requirements while being extremely simple in terms of processing, use, and maintenance. In this embodiment, the baffle 14 is cylindrical and has an exposed area 141. The baffle 14 can rotate on the housing 1. When the exposed area 141 rotates to the position corresponding to the opening 13, the second chamber 12 enters the open state.

[0049] Finally, a limiting seat 124 is also required in the second chamber 12 to limit the charging plug 23. When the second chamber 12 is open, the user can pull the charging plug 23 out of the limiting seat 124 to perform the charging operation. The limiting seat 124 serves to keep the charging plug 23 in a preset position for easy access by the user. (See also...) Figure 4 The limiting seat 124 is equipped with a magnetic element M, which allows the charging plug 23 to be attracted to the limiting seat 124. And as... Figure 5As shown, the charging cable 2 includes a first segment 24 wound on a reel 182 and a second segment 25 exposed outside the reel 182. The end of the second segment 25 has a stop portion 26 that can engage with the corresponding opening 183 of the reel 182. Correspondingly, a preset chamber 125 for accommodating the second segment 25 is provided between the limiting seat 124 of the second chamber 12 and the partition 10. The preset chamber 125 communicates with the cable passage portion 101 of the partition 10 and the limiting seat 124. The provision of this preset chamber 125 to accommodate the second segment 25 prevents the charging cable 2 from being obstructed by the reel 182.

[0050] The specific usage process of the charging structure in this embodiment is as follows:

[0051] like Figures 6-7 As shown, the charging structure in this embodiment is applied to a smart home device, which is a smart toilet and includes a main body and a circuit structure for power supply. The main body also has a built-in charging structure as described above, which is electrically coupled to the circuit structure. Smart home devices require the circuit structure to be connected to a power source such as a socket in the room to function. Therefore, the circuit structure for power supply allows the charging structure to charge electronic products. Furthermore, embedding the charging structure within the main body of the smart home device protects the charging structure, further preventing issues such as humidity affecting its use. Figure 6 As shown, at this time, the opening 13 is closed by the baffle 14, and the charging plug 23 is isolated in the second chamber 12. As the baffle 14 rotates on the housing 1, when the exposed area 141 rotates to the position corresponding to the opening 13, as... Figure 7 As shown, the second chamber 12 is in the open state, at which time the user can remove the charging plug 23 for charging. Since the second chamber 12 in this embodiment is located outside the smart home, it is suitable for smart homes with small size or space, and because the second chamber 12 is located outside the smart home, it is more convenient for users to access and use the charging structure.

[0052] Example 2

[0053] like Figures 8-9 As shown, the structure is basically the same as that of Embodiment 1, except that the baffle 14 in this embodiment is semi-cylindrical, and the baffle 14 is hinged to the housing 1 via shaft Z. Again, taking a smart toilet as an example, the situation where the second chamber 12 is in the closed state will not be described further. Figure 9 As shown, as the baffle 14 rotates around the axis Z, the baffle 14 no longer blocks the second chamber 12, causing the second chamber 12 to enter the open state. Compared with the charging structure in Embodiment 1, the charging structure in this embodiment is faster in switching.

[0054] Example 3

[0055] like Figures 10-18 As shown, the structure is basically the same as that of Embodiment 1, except that the structure of the second chamber 12 in this embodiment is different. Specifically, see [link to embodiment 1]. Figures 10-12 The baffle 14 is confined to the outer end of the pull-out plate 15. When pressed, the pull-out plate 15 can slide to open or close the opening 13. The pull-out plate 15 has two sides with upwardly protruding edges extending along its sliding direction; these two edges can be named the first edge 151 and the second edge 152, respectively. Both the first edge 151 and the second edge 152 have notches 153 for easy access by the user to remove the charging plug 23. Figures 13-14 As shown, a guide rail 155 protrudes from the bottom 154 of the pull-out plate 15. The second chamber 12 has a guide portion 122 on the corresponding bottom wall 121, allowing the guide rail 155 to slide. A limiting member 123 is also provided on the bottom wall 121, thereby limiting the pull-out plate 15 when it moves outward. The guide rail 155 and the guide portion 122 cooperate with each other and with the first edge 151 and the second edge 152, so that the pull-out plate 15 can only slide along the guide portion 122. This allows the baffle 14 to accurately open or close the opening 13. The limiting member 123 prevents the pull-out plate 15 from disengaging from the second chamber 12 during outward sliding. In this embodiment, a self-locking switch 16 is also provided in the second chamber 12 to switch the corresponding state of the pull-out plate 15. When the baffle 14 is in the closed state, blocking the opening 13, the pull-out plate 15 is locked by the self-locking switch 16. This self-locking switch 16 is configured so that pressing the pull-out plate 15 releases the lock. When the pull-out plate 15 is unlocked, it can slide open the opening 13 along with the baffle 14. When the baffle 14 slides back to the position blocking the opening 13, the pull-out plate 15 is locked again by the self-locking switch 16. Figure 13 As shown, a lock seat 156 adapted to the self-locking switch 16 is provided on the bottom 154 of the pull-out plate 15. Furthermore, an elastic element 17 is provided on the partition 10 inside the second chamber 12 to assist the pull-out plate 15 in moving outward when pressed. This elastic element 17 is a spring component that ensures the pull-out plate 15 always has a tendency to slide outward, allowing it to slide a certain distance outward when the self-locking switch 16 is released, facilitating the user's access to the charging plug 23.

[0056] Finally, see Figure 12In this embodiment, the limiting seat 124 is disposed on the pull-out plate 15. A preset chamber 125 capable of accommodating the second segment 25 is provided between the limiting seat 124 of the second chamber 12 and the partition 10, and the preset chamber 125 is connected to the wire-passing portion 101 of the partition 10 and the limiting seat 124. The preset chamber 125 is provided to accommodate the second segment 25, so that the previously reserved second segment 25 can move with the pull-out plate 15 when it slides outward, thereby avoiding the situation where the pull-out plate 15 is blocked by the winding reel 182.

[0057] The specific usage process of the charging structure in this embodiment is as follows:

[0058] like Figure 15 As shown, at this time, the opening 13 is closed by the baffle 14, the lock seat 156 on the bottom 154 of the pull-out plate 15 is locked by the self-locking switch 16, and the elastic element 17 is pressed by the end of the guide rail 155 and the partition 10. At this time, the spring makes the pull-out plate 15 always have a tendency to slide outward; as Figure 16 As shown, when the user presses the baffle 14, the lock seat 156 is released from the self-locking switch 16. Under the action of the elastic member 17, the guide rail 155 slides outward along the guide portion 122, causing the opening 13 to open. The end of the guide rail 155 is blocked by the limiting member 123 to prevent the pull-out plate 15 from disengaging from the second chamber 12. Compared to Embodiment 1, this embodiment is suitable for smart homes with sufficient space, allowing the second chamber 12 to be built into the smart home, further improving the isolation of the second chamber 12. Therefore, taking a smart massage chair as an example... Figure 17 As shown, the second chamber 12 is in the closed state at this time, as... Figure 18 As shown, the second chamber 12 is in the open state.

[0059] Example 4

[0060] like Figure 19 As shown, the structure is basically the same as that of Embodiment 3. The difference is that in this embodiment, the limiting seat 124 is set on the bottom 154 of the pull-out plate 15. Correspondingly, a magnetic element M is provided on the limiting seat 124 so that the charging plug 23 is attracted to the limiting seat 124. The charging structure in this embodiment is also applicable to the above-mentioned smart toilet, smart massage chair and other smart home devices.

[0061] Example 5

[0062] like Figures 20-22 As shown, the structure is basically the same as that of Embodiment 3, except that in this embodiment, the partition 10 is located above the cable reel 18, and the limiting seat 124 is disposed on the partition 10. A sliding plate 14' is provided above the partition 10, which together with the partition 10 forms the second chamber 12. This charging structure opens or closes the second chamber 12 by the user operating the sliding plate 14'. Taking a smart mahjong table as an example... Figure 21 The diagram shows the charging structure installed on a smart mahjong table. As the sliding plate 14' moves, see... Figure 22 The second chamber 12 is opened to allow access to the charging plug 23. This embodiment is also applicable to the aforementioned smart toilets, smart massage chairs, and other smart home devices.

[0063] Example 6

[0064] The structure is basically the same as that of Embodiment 3, except that the baffle 14 is directly connected to the periphery of the opening 13 of the second chamber 12 by means of hinge or snap-fit.
