[0041] See also Figure 1-12 As shown, this embodiment discloses a wall-embedded charging station, which includes:

[0042] A shell 1, one side of which is open, and the shell 1 is embedded in the wall;

[0043] A panel 2, the panel 2 covers the opening side of the housing 1, and together with the housing 1 forms a receiving cavity 11;

[0044] A charging cable 3, which extends from the accommodating cavity 11 to the outside of the panel 2;

[0045] A power module 4 is disposed in the accommodating cavity 11; the power module 4 is connected to an external power supply circuit, and the charging line 3 is electrically connected to the power module 4;

[0046] The wire winding device 5 is arranged in the accommodating chamber 11, and the charging wire 3 is wound around the wire winding device 5; the wire winding device 5 comprises: an installation box 51, a wire reel 52, a rotating shaft 53 and a coil spring (not shown in the figure); the installation box 51 is connected to the housing 1 and is arranged in the accommodating chamber 11, the rotating shaft 53 is rotatably connected in the installation box 51, and the wire reel 52 is fixedly connected to the rotating shaft 53; the charging wire 3 is wound around the rotating shaft 53, and one end is connected to the rotating shaft 53; one end of the coil spring is fixedly connected to the rotating shaft 53 or the wire reel 52, and the other end is fixedly connected to the installation box 51, and the coil spring is spirally distributed with the rotating shaft 53 as the center.

[0047] The installation process of the wall-embedded charging station in this embodiment is as follows: the shell 1 is embedded in the groove reserved on the wall, and can be connected to the wall by screwing, snapping or other means; the power module 4 is connected to the neutral wire and the live wire of the external power supply circuit, and the voltage is converted to transmit electrical energy to the charging cable 3; ensure that the power module 4 and the winding device 5 are installed in place, and ensure that the charging cable 3 passes through the panel 2 and then covers the panel 2, and the panel 2 is connected to the shell 1 by screwing, snapping or other means.

[0048] The principle of retracting and pulling the charging cable 3 of this embodiment is as follows: the rotating shaft 53 is rotatably connected to the installation box 51, one end of the charging cable 3 is connected to the rotating shaft 53, and the other end is wrapped around the rotating shaft 53 and extends to the outside of the accommodating chamber 11. The end of the charging cable 3 is pulled away from the rotating shaft 53, which drives the rotating shaft 53 to rotate, so that the charging cable 3 rotates relative to the installation box 51. Under the action of external tension, the charging cable 3 continuously moves outward, thereby achieving the pulling out of the charging cable 3; one end of the coil spring is fixed, and the other end rotates with the rotating shaft 53 or the winding drum 52. In the process of pulling out the charging cable 3, one end of the coil spring rotates, causing the coil spring to stretch or twist, generating elastic force. When the charging cable 3 is loosened, the coil spring releases the elastic force to restore the natural state, pushing the rotating shaft 53 and the winding drum 52 to rotate. The rotation of the rotating shaft 53 or the winding drum 52 drives the charging cable 3 to rewind, thereby achieving the retraction of the charging cable 3.

[0049] The wall-embedded charging seat of the present embodiment is provided with a charging cable 3 with one end exposed outside the accommodating cavity 11, and a winding device 5 is provided to wind the charging cable 3, so that the charging cable 3 is rotated in the installation box 51, so that the user can pull out the charging cable 3 of an appropriate length as needed, and insert it into the charging port of the electronic product for charging, thereby avoiding the problem of forgetting to carry the charging cable 3 and being unable to charge, and improving the convenience of using the wall-embedded charging seat; by arranging a winding spring in the winding device 5, the rotation of the rotating shaft 53 or the winding drum 52 is realized to drive the charging cable 3 to rewind, so that the winding device 5 automatically stores the charging cable 3 when charging is finished, and the user does not need to store and carry it, thereby preventing the charging cable 3 from being lost and providing a good user experience; the charging cable 3 is automatically rewound by the winding device 5, thereby avoiding a large area of ​​the charging cable 3 being exposed to contact with other objects to cause entanglement and wear, thereby ensuring the service life of the charging cable 3 and the wall-embedded charging seat; the wall-embedded charging seat of the present embodiment is small in size and suitable for many application scenarios, such as hotels, shopping malls, stations, airports and other places.

[0050] In one embodiment, the end of the charging cable 3 extending outside the panel 2 is an output end, and the output end type of the charging cable 3 is Lighting, Micro-USB, Type-C or other types. The end of the charging cable 3 away from the rotating shaft 53 is used to connect electronic products, and can be used to charge various electronic products such as mobile phones, tablet computers, e-books, digital cameras, etc. The charging cable 3 can be adapted to set any type of output end for electronic products, and can also be set with multiple output ends of different types, so that the charging cable 3 is an all-in-one charging cable 3, and the compatibility of the charging cable 3 is improved. The charging cable 3 is set with multiple output ends, which is a prior art and will not be described in detail here.

[0051] In one embodiment, the cable reel 52 is provided with a mounting groove 521, and the mounting groove 521 is distributed in an arc shape with the rotating shaft 53 as the center; a coil spring is arranged in the mounting groove 521, one end of the coil spring is fixedly connected to the groove wall of the mounting groove 521, and the other end is fixedly connected to the mounting box 51. The mounting groove 521 limits the stretching or twisting of the coil spring in a limited area, one end of the coil spring connected to the mounting box 51 is a fixed end, and one end of the coil spring connected to the groove wall of the mounting groove 521 is a movable end. The cable reel 52 rotates or stops with the rotating shaft 53, and the movable end of the coil spring rotates or stops with the cable reel 52. When the cable reel 52 rotates, the coil spring is in a twisted state and gradually stores energy. When the cable reel 52 stops rotating, the coil spring releases energy and rotates in the direction of restoring the natural state, driving the cable reel 52 to rotate in the opposite direction of the extension direction of the charging cable 3.

[0052] In one embodiment, a mounting post 511 is protruded from one side of the mounting box 51 near the mounting groove 521. The mounting post 511 extends from the mounting box 51 toward the cable reel 52, and the mounting post 511 is coaxially arranged with the rotating shaft 53; the coil spring is fixedly connected to the mounting post 511. The mounting post 511 is close to the cable reel 52, so that the fixed end and the movable end of the coil spring are in the same plane, so as to prevent the coil spring from being deflected during the twisting and releasing process and affecting the elasticity of the coil spring; there is a gap between the mounting post 511 and the cable reel 52, so as to prevent the mounting post 511 from rotating with the cable reel 52, and ensure the stability of the fixed end of the coil spring.

[0053] In one embodiment, a limiting groove 522 is provided in the direction in which the mounting groove 521 extends toward the rotating shaft 53, and the limiting groove 522 is coaxially arranged with the rotating shaft 53, and one end of the mounting post 511 close to the rotating shaft 53 is inserted into the limiting groove 522. The limiting groove 522 ensures that the mounting post 511 is coaxial with the rotating shaft 53, limits the movement of the mounting post 511, improves the structural stability of the winding device 5, and prevents the mounting post 511 from bending due to the tension of the coil spring, thereby causing the coil spring to deflect.

[0054] In one embodiment, the cable winding device 5 further includes: a self-locking component 54; the self-locking component 54 is connected to the installation box 51 and the cable winding reel 52, and is used to lock or unlock the cable winding reel 52. After the user pulls out the charging cable 3 to a specified length, the pulling of the charging cable 3 is stopped, and the self-locking component 54 drives the cable winding reel 52 to lock to stop rotating; after the user unplugs the charging cable 3 from the electronic product and releases the charging cable 3, the self-locking component 54 drives the cable winding reel 52 to unlock and rotate under the drive of the winding spring.

[0055] In one embodiment, the self-locking assembly 54 includes: a ratchet 541, a pawl 542, an elastic member and a limit block 544; the ratchet 541 is fixedly connected to the cable reel 52, and the pawl 542 is rotatably connected to the mounting box 51; the limit block 544 is fixedly connected to the mounting box 51; the elastic member is connected to the mounting box 51, disposed between the limit block 544 and the pawl 542, and abuts against the pawl 542, and the elastic member is used to drive the pawl 542 to abut against or away from the ratchet 541. The pawl 542 abuts against the ratchet 541 in the direction of pulling the charging cable 3 outward, so that the ratchet 541 cannot rotate in the direction of rewinding the charging cable 3, thereby preventing the ratchet 541 and the cable reel 52 from reversing; the pawl 542 leaves the ratchet 541, and the ratchet 541 is not subjected to the abutting force of the pawl 542. Under the action of the winding spring, the ratchet 541 rotates with the cable reel 52.

[0056] In one embodiment, the ratchet 541 includes: a plurality of ratchet teeth 5411; the plurality of ratchet teeth 5411 are distributed in a circular array with the rotating shaft 53 as the center, and there is a spacing between adjacent ratchet teeth 5411; the end of the ratchet teeth 5411 away from the center of the circle and opposite to the pulling direction of the charging cable 3 is stepped, and the height of the ratchet teeth 5411 increases from the side close to the center of the circle to the side away from the center of the circle. The stepped end faces away from the pulling direction of the charging cable 3, and the pawl 542 abuts against the stepped end to block the rotation of the ratchet 541, thereby locking the ratchet 541 and the pawl 542; the pawl 542 rotates until the pawl 542 is disengaged from the ratchet teeth 5411 and the pawl 542 is located between adjacent ratchet teeth 5411, and then the locking between the pawl 542 and the ratchet 541 is released. In this case, when the charging cable 3 is released, the ratchet 541 rotates, and the ratchet teeth 5411 push the pawl 542 away from the pulling direction of the charging cable 3, so that the pawl 542 cannot abut against the ratchet teeth 5411, thereby unlocking the ratchet 541 and the pawl 542. The rotation of the pawl 542 can be driven by an electric drive, a mechanical button, or controlled by an elastic member.

[0057] In one embodiment, the elastic member is a U-shaped spring piece 543, the installation box 51 is provided with two columns 512, and the U-shaped spring piece 543 is sleeved outside the two columns 512; the opening side of the U-shaped spring piece 543 is provided corresponding to the ratchet 541, the pawl 542 is provided in the U-shaped spring piece 543, and extends toward the ratchet 541 through the opening side of the U-shaped spring piece 543; the pawl 542, the U-shaped spring piece 543 and the limit block 544 are located at the top of the ratchet 541. The limit block 544 is provided outside the U-shaped spring piece 543, and is used to resist the U-shaped spring piece 543. The pawl 542 rotates in the U-shaped spring piece 543, and driven by the ratchet 541, it presses against the inner wall of the U-shaped spring piece 543, and the pawl 542 reaches the maximum rotation angle and stops rotating. The U-shaped spring piece 543 limits the rotation angle of the pawl 542, and the U-shaped spring piece 543 has elastic force, which facilitates the pawl 542 to return to the initial rotation angle.

[0058] In one embodiment, the installation box 51 is provided with a connecting column 513, the connecting column 513 is arranged in the U-shaped spring sheet 543, and the pawl 542 is sleeved on the connecting column 513. The pawl 542 is sleeved on the connecting column 513 to achieve a rotational connection with the installation box 51.

[0059] In one embodiment, there are two limit blocks 544, which are arranged on the side of the column 512 close to the ratchet 541 and distributed on both sides of the U-shaped spring piece 543; the distance between the two limit blocks 544 is greater than the distance between the two columns 512. The two limit blocks 544 limit the U-shaped spring piece 543 on both sides of the U-shaped spring piece 543, thereby limiting the rotation angle of the pawl 542; at the same time, the two limit blocks 544 and the two columns 512 clamp the U-shaped spring piece 543, preventing the spring piece from detaching from the column 512, thereby ensuring the structural stability and reliability of the self-locking assembly 54.

[0060] In one embodiment, the pawl 542 is provided with a protruding tip 5421, and a limiting portion 5431 is provided inwardly on a side of the U-shaped spring sheet 543 away from the panel 2, and the tip 5421 moves between the limiting portion 5431 and the column 512 away from the limiting portion 5431. The limiting portion 5431 and the column 512 block the tip 5421 of the pawl 542, so that the tip 5421 of the pawl 542 can only move between the limiting portion 5431 and the column 512, so as to limit the movement range of the end of the pawl 542 close to the ratchet wheel 541.

[0061] In one embodiment, a slope 5422 is provided at the end of the ratchet 542 away from the pulling-out direction of the charging cable 3, and a guide surface 5423 is provided at the end close to the pulling-out direction of the charging cable 3, and the guide surface 5423 and the slope 5422 are arranged in a "V" shape; the ratchet tooth 5411 includes: a first step 54111 and a second step 54112, and the second step 54112 is arranged on the side of the first step 54111 close to the center of the ratchet 541; the first step 54111 and the second step 54112 form a height difference with the end opposite to the pulling-out direction of the charging cable 3, and the other end is flush. The side of the ratchet tooth 5411 with a height difference provides abutment space for the ratchet 541; the end of the first step 54111 that is flush with the second step 54112 pushes the inclined surface 5422 when the ratchet tooth 5411 rotates in the pulling direction following the charging cable 3, and the inclined surface 5422 has a guiding function to prevent the pawl 542 from blocking the forward rotation of the ratchet 541 and affecting the pulling out of the charging cable 3; when the charging cable 3 is retracted, the first step 54111 abuts against and pushes the guide surface 5423, and the guide surface 5423 has a guiding function to prevent the pawl 542 from blocking the reverse rotation of the ratchet 541 and affecting the retraction of the charging cable 3.

[0062] See also Fig. 9 , Fig. 9Schematic diagram of the initial state of the self-locking assembly 54. In this state, the charging cable 3 is not subjected to the pulling force, the cable reel 52 and the rotating shaft 53 are in a stationary state, and the self-locking assembly 54 locks the cable reel 52. The tip 5421 of the pawl 542 abuts against the limiting portion of the U-shaped spring sheet 543, the side of the pawl 542 away from the inclined surface 5422 abuts against the side of the U-shaped spring sheet 543 opposite to the limiting portion, and the end of the pawl 542 close to the ratchet 541 abuts between the first step 54111 and the second step 54112 of the ratchet tooth 5411.

[0063] See also Fig.10 , Fig.10 Schematic diagram of the state of the self-locking component 54 during the pulling out process of the charging cable 3 in this embodiment. When the charging cable 3 is pulled out, the cable reel 52 is driven to rotate in the counterclockwise direction, and the ratchet tooth 5411 rotates counterclockwise along with the cable reel 52. The end of the ratchet tooth 5411 that is flush with the first step 54111 and the second step 54112 abuts against the inclined surface 5422 of the pawl 542, and slides relative to the inclined surface 5422 of the pawl 542, causing the inclined surface 5422 to abut against the limiting portion of the U-shaped spring sheet 543, and the side of the pawl 542 away from the inclined surface 5422 abuts against the side of the U-shaped spring sheet 543 opposite to the limiting portion. After the charging cable 3 stops being pulled out, the state of the self-locking component 54 is the same as Fig. 9 The state of the self-locking assembly 54 shown in FIG.

[0064] See also Fig.11 , Fig.11 Schematic diagram of the first state of the self-locking assembly 54 during the retraction process of the charging cable 3 in this embodiment. After the charging cable 3 is used, it is pulled out a short distance, and the ratchet teeth 5411 rotate counterclockwise along with the charging cable 3 by a certain angle, so that the pawl 542 gradually slides from the second step 54112 to between the two ratchet teeth 5411, and there is a gap between the two sides of the pawl 542 and the U-shaped spring sheet 543. The pawl 542 droops due to its own gravity, and the end close to the ratchet 541 naturally points to the center of the ratchet 541.

[0065] See also Fig.12 , Fig.12Schematic diagram of the second state of the self-locking assembly 54 during the retraction process of the charging cable 3 in this embodiment.
