[0036] Please refer to Figures 1 to 8 , an embodiment of the present utility model discloses a concealed charger, which includes: a charging head 1 and a charging cable 2. The charging head 1 is internally provided with a charging circuit. A wire body accommodating groove 11 is provided on the charging head 1. A connection hole 13 is opened at one end of the wire body accommodating groove 11, and a plug accommodating groove 12 is opened at the other end; the charging cable 2 includes a wire body 21 and a plug 22. The plug 22 is connected to one end of the wire body 21. The wire body 21 is located in the wire body accommodating groove 11. The plug 22 is detachably connected to the plug accommodating groove 12. The other end of the wire body 21 passes through the connection hole 13 and is electrically connected to the charging circuit. When a user needs to use the charger for charging, the charging cable 2 can be pulled out from the wire body accommodating groove 11, and the plug 22 is inserted into the device to be charged. At this time, the charging circuit starts to work, and transmits electric energy to the device through the wire body 21; when the charging is completed, the user can pull out the plug 22 from the device, squeeze the wire body 21 into the wire body accommodating groove 11, and put the plug 22 into the plug accommodating groove 12 to realize the storage of the charging cable 2. By designing the charging head 1 and the charging cable 2 as an integrated whole, the charger is more convenient to carry, reduces the risk of forgetting to carry the charging cable 2. The charging cable 2 can be neatly stored in the wire body accommodating groove 11, avoiding the winding problem after long-term carrying and use. The plug 22 can be stored in the plug accommodating groove 12, avoiding the risk of being polluted or damaged when exposed to the external environment when not in use.

[0037] Furthermore, the wire accommodating groove 11 is formed along the outer circumference of the charger head 1, making full use of the outer contour space of the charger head 1 and reducing the need for additional storage space.

[0038] Furthermore, a first connecting member 121 is provided in the plug accommodating groove 12, and a second connecting member is provided on the plug 22. The first connecting member 121 and the second connecting member are magnetically connected. In this embodiment, the magnetic connection principle is adopted. When the plug 22 is received in the plug accommodating groove 12, the first connecting member 121 and the second connecting member are attracted to each other by magnetic force, realizing the stable connection and fixation of the plug 22. After charging is completed, the user pulls the plug 22 out of the charging device and brings the plug 22 close to the plug accommodating groove 12. Due to the magnetic attraction between the first connecting member 121 and the second connecting member, the plug 22 will be automatically adsorbed into the plug accommodating groove 12. After the plug 22 is completely received in the plug accommodating groove 12, the magnetic force between the first connecting member 121 and the second connecting member ensures that the plug 22 is stably fixed in the groove and is not easily detached or shaken. When the user needs to use the charger again, simply pull the plug 22 gently to overcome the magnetic attraction, and the plug 22 can be taken out of the plug accommodating groove 12.

[0039] Specifically, both the first connecting member 121 and the second connecting member are magnets; or one of the first connecting member 121 and the second connecting member is a magnet, and the other is an iron sheet. It can be understood that a magnet has the property of attracting magnetic materials such as iron, nickel, and cobalt. When two magnets or a magnet and an iron sheet are close to each other, an attractive force will be generated between them. Using the combination of a magnet or a magnet and an iron sheet can ensure a more stable and reliable connection between the plug 22 and the plug accommodating groove 12, avoiding shaking or detachment during carrying or storage.

[0040] Specifically, there are two second connecting members, which are respectively arranged on both sides of the end of the plug 22 facing the plug 22 accommodating hole. The first connecting member 121 and the second connecting members are arranged in one-to-one correspondence. When the plug 22 is received in the plug accommodating groove 12, the two groups of first connecting members 121 and the second connecting members are attracted to each other by magnetic force, forming multi-point fixation, thereby improving the stability of the plug 22 during storage. The stable storage state makes the charger more convenient and reliable during carrying and storage, reduces the trouble caused by the detachment or shaking of the plug 22, and enhances the user experience.

[0041] Specifically, the first connecting member 121 is arranged at the bottom of the plug accommodating groove 12 in the insertion direction of the plug 22.

[0042] In one embodiment, an elastic switch 122 is provided at the bottom of the plug receiving groove 12 in the insertion direction of the plug 22. The elastic switch 122 has a first state and a second state. When the plug 22 abuts against and presses the elastic switch 122, the elastic switch 122 switches from the first state to the second state, or from the second state to the first state; when the elastic switch 122 is in the first state, the second connecting member approaches the first connecting member 121 so that the first connecting member 121 and the second connecting member are magnetically attracted and connected; when the elastic switch 122 is in the second state, the second connecting member moves away from the first connecting member 121 so that the portion of the plug 22 close to the wire body 21 passes through the plug receiving groove 12 and is exposed. It can be understood that in this embodiment, the mechanical movement of the elastic switch 122 is combined with the magnetic attraction connection between the first connecting member 121 and the second connecting member. When the plug 22 is inserted, it will first abut against and press the elastic switch 122, causing it to switch from one state to another. In different states of the elastic switch 122, the telescopic length of the elastic switch 122 in the direction of the plug 22 is different, resulting in a change in the relative position between the second connecting member (located on the plug 22) and the first connecting member 121 (located inside the charger), thereby controlling the magnetic attraction connection or disconnection between them. Specifically, when the plug 22 is received in the plug receiving groove 12, the elastic switch 122 is in the first state. At this time, the second connecting member approaches the first connecting member 121, and the plug 22 is firmly fixed in the plug receiving groove 12 by magnetic attraction connection; when the user needs to take out the plug 22, the plug 22 can be pressed towards the plug receiving groove 12. At this time, the bottom of the plug 22 will press the elastic switch 122. As the plug 22 presses and continues to insert the elastic switch 122, the elastic switch 122 switches from the first state to the second state, so that the telescopic length of the elastic switch 122 in the direction of the plug 22 becomes longer, and the relative position between the second connecting member and the first connecting member 121 changes, causing the magnetic attraction connection between them to be disconnected, and the portion of the plug 22 close to the wire body 21 passes through the plug receiving groove 12 and is exposed. The user can grasp the exposed portion and pull out the plug 22 from the plug receiving groove 12. It should be explained that the elastic switch 122 belongs to the prior art and can be referred to but not limited to the elastic pressing portion on a ballpoint pen, which will not be elaborated here.

[0043] Further, the hidden charger of this solution further includes a power connection metal sheet 3. A metal sheet accommodating groove 14 is provided on the charger head 1. One end of the power connection metal sheet 3 is rotatably connected to one end of the metal sheet accommodating groove 14 and is electrically connected to the charging circuit. The power connection metal sheet 3 can be rotatably accommodated in the metal sheet accommodating groove 14. It can be understood that one end of the power connection metal sheet 3 is connected to one end of the metal sheet accommodating groove 14 through a rotational connection (such as a hinge, a rotating shaft, etc.) and maintains an electrical connection with the charging circuit. When the charger is working, the other end of the power connection metal sheet 3 can be rotated out of the metal sheet accommodating groove 14 and exposed to the outside to make it contact with the power source; when not in use, the power connection metal sheet 3 can be rotated back into the metal sheet accommodating groove 14 to achieve accommodation.

[0044] Further, a data cable socket 15 is also provided on the charger head 1. The data cable socket 15 is electrically connected to the charging circuit and is used to dock with an external data cable. It should be explained that the data cable socket 15 is designed according to internationally common interface standards (such as USB-A, USB-C, Micro-USB, etc.) to ensure compatibility with most external data cables on the market. Conductive contacts are provided inside the data cable socket 15, and the conductive contacts are electrically connected to the charging circuit. When an external data cable is inserted, a stable electrical connection can be formed, thereby realizing the transmission of electric power. By providing the data cable socket 15, users can use an external data cable for charging, avoiding the situation where the charger cannot be used after the built-in charging cable 2 is damaged.

[0045] Specifically, the metal sheet accommodating groove 14 is provided on the upper side or the lower side of the charger head 1, and the wire body accommodating groove 11, the connection hole 13, and the plug accommodating groove 12 are provided on the horizontal outer periphery of the charger head 1.

[0046] Compared with the prior art, the hidden charger of the present utility model integrates the charger head and the charging cable, improving portability. Through the design of the wire body accommodating groove and the plug accommodating groove, the accommodation of the charging cable and the plug is realized, avoiding the problems of entanglement and exposure.

[0047] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
