[0002] With the development of knob technology, more and more household appliances are controlled by knobs. Users can operate and control household appliances by rotating knobs and buttons. In order to improve user experience, the knob can be fixed on the household appliance or taken down and used as a remote control. However, in either case, the battery power in the knob will be gradually consumed during use. When the battery power is exhausted, the battery needs to be replaced or charged before the knob can resume function. In order to facilitate charging the battery of the above-mentioned knob, a charging structure is provided on the panel of the household appliance, and in order to facilitate the knob to be taken down and used as a remote control, the charging structure is a wireless charging mode.

Thus, wireless charging of the detachable control device is achieved while maintaining the metal appearance of the appliance body as much as possible.

[0004] In the prior art, in order to achieve the detachability of the control device, a corresponding magnet is set in the panel or the operating surface, and the control device is firmly adsorbed on the electrical appliance body through the adsorption effect of the magnet. With the intelligence of electrical appliances, more and more control devices on the panel not only control the electrical appliances, but also serve as display components to display functional information of the electrical appliance operation, so that the installation orientation of the control device needs to ensure that the displayed information is not inverted or tilted. In the prior art, when no less than one magnet is installed, since the installation orientations of multiple magnets are not unique, when the magnet deviates from the predetermined positive installation orientation, the control device will deflect with the position of the magnet after the control device is adsorbed, so that the information displayed by the control device is inverted or tilted, affecting the user experience.

Under the adsorption effect of the magnetic suction component and the fixed position of the magnetic suction component, the orientation of the component to be charged after adsorption is unique, and when the component to be charged is used as a display component to display functional information, the displayed information is prevented from being inverted or tilted to affect the user's usage experience.

[0053] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0054] First embodiment:

[0055] like Figure 1 As shown, the present invention provides a wireless charging structure, including a fixing base 1 and a charger 2, wherein the fixing base 1 is used to be fixedly connected to a panel 3 to be installed. Figure 2 As shown, the charger 2 includes a charging head 21 exposed outside the fixing base 1 and a charging base 22 hidden inside the fixing base 1. The charging head 21 is embedded in the fixing base 1 and electrically connected to the charging base 22. The fixing base 1 can be fixed to the inner side of the panel 3 by welding; or it can be detachably fixed to the inner side of the panel 3 by screws.

[0056] like Figure 3As shown, a magnetic suction member 4 is installed in the charging seat 22. In this embodiment, a plurality of magnetic suction members 4 are installed in the charging seat 22. The magnetic suction members 4 absorb the component to be charged to fix the component to be charged. At this time, the distribution orientation of the plurality of magnetic suction members 4 is a predetermined installation orientation. If the magnetic suction member 4 rotates a certain angle with the charging seat 22, causing the plurality of magnetic suction members 4 to deviate from the predetermined installation orientation, when the component to be charged is adsorbed on the panel 3, it will deviate from the predetermined installation orientation along with the deviated magnetic suction member 4. When the component to be charged is used as an information display component, it is usually necessary to avoid the displayed information from being inverted or tilted to facilitate the user to view the displayed information. Therefore, in order to avoid the component to be charged from being inverted or tilted, the charging seat 22 is connected to the fixed seat 1 and needs to be restricted from rotating during the installation process, so that the distribution orientation of the plurality of magnetic suction members 4 remains fixed during the installation process, and the position after installation is in the predetermined installation orientation, thereby avoiding the component to be charged from deviating from the pre-installed orientation when the magnetic suction member 4 absorbs the component to be charged, so that the displayed information is inverted or tilted.

[0057] Specifically, Figure 3 and Figure 4 As shown, a first anti-rotation structure is provided on the inner side of the fixed base 1, and the first anti-rotation structure is an anti-rotation column 11, which extends from front to rear. A second anti-rotation structure is provided on the side of the charging base 22 facing the fixed base 1, and the second anti-rotation structure is a positioning hole 2211. When the charging base 22 is connected to the fixed base 1, the anti-rotation column 11 is inserted into the positioning hole 2211 and cooperates with the positioning hole 2211 to limit the rotation of the charging base 22 during the installation process, thereby fixing the magnetic suction component 4 in a predetermined installation position during the installation process of the charging base 22 to prevent the magnetic suction component 4 from deviating from the predetermined installation position.

[0058] In order to improve the effect of limiting the rotation of the charging base 22, a plurality of anti-rotation posts 11 are distributed circumferentially, and a plurality of positioning holes 2211 are distributed circumferentially. In the present embodiment, there are three anti-rotation posts 11 and three positioning holes 2211. When installing the charging base 22, a plurality of positioning holes 2211 are plugged into a plurality of anti-rotation posts 11 in a one-to-one correspondence so that the magnetic attraction component 4 is distributed in a predetermined position so that the magnetic attraction component 4 is in a predetermined installation orientation, thereby preventing the charging base 22 from rotating relative to the fixed base 1 during the installation process; after the anti-rotation posts 11 are plugged into the positioning holes 2211, in order to prevent the charging base 22 from axially separating from the fixed base 1 during the installation process, the anti-rotation posts 11 are provided with a first screw hole 111, and a first screw is provided between the charging base 22 and the anti-rotation posts 11. The first screw passes through the charging base 22 from back to front and cooperates with the first screw hole 111 on the anti-rotation posts 11, thereby fixing the charging base 22 to the fixed base 1, thereby preventing the charging base 22 from axially separating from the fixed base 1. In the present embodiment, Figure 5As shown, the first anti-rotation structure can also be on the side of the charging base 22 facing the fixed base 1, and the first anti-rotation structure is the anti-rotation column 11. At this time, the anti-rotation column 11 extends from the rear to the front, and the inner side of the fixed base 1 is provided with a second anti-rotation structure. The second anti-rotation structure is a positioning hole 2211. When the charging base 22 is connected to the inner side of the fixed base 1, the anti-rotation column 11 is inserted into the positioning hole 2211 to limit the rotation of the charging base 22.

[0059] In this embodiment, if Figure 6 As shown, the fixing base 1 is provided with a positioning boss 13 on one side facing the charging base 22, and the outer side of the fixing base 1 is provided with a placement groove 14 for accommodating the charging head 21. The fixing base 1 is also provided with a non-circular plug hole 131, which is located on the positioning boss 13 and communicates with the placement groove 14. Figure 4 As shown, the side of the charging seat 22 facing the fixed seat 1 is provided with a plug-in slot 2213 and a first receiving slot 2214. The first receiving slot 2214 is on the side of the charging seat 22 facing the fixed seat 1. A contact surface 2215 is formed between the first receiving slot 2214 and the plug-in slot 2213. After the charging seat 22 is sleeved on the positioning boss 13, the positioning boss 13 contacts the contact surface 2215. Figure 7 As shown, the charging head 21 includes a first base 211 and a second base 212 that protrudes relative to the first base 211 toward the charging base 22. The cross-section of the outer peripheral wall of the second base 212 is non-circular. In this embodiment, as shown in FIG. Figure 6 and Figure 7 As shown, the non-circular cross-sections of the plug hole 131 and the outer peripheral wall of the second seat body 212 are D-shaped that are adapted to each other. When the charging head 21 is connected to the charging base 22, the first seat body 211 abuts against the bottom wall of the placement groove 14, and the second seat body 212 passes through the plug hole 131 and is plugged into the plug groove 2213. The non-circular shape of the second seat body 212 cooperates with the non-circular shape of the plug hole 131 and the groove wall of the plug groove 2213 to limit the rotation of the charging base 22, thereby preventing the charging base 22 from rotating during the installation process so that the magnetic suction component 4 deviates from the predetermined installation orientation.

[0060] In order to improve the stability of the connection between the charging base 22, the fixing base 1 and the charging head 21, as shown in FIG.

The base 221 is connected to the fixed base 1, and the rear shell 223 is covered on the rear side of the base 221. The magnetic member 4 is clamped and fixed by the base 221 and the rear shell 223. The rear shell 223 is provided with a first fastener, which passes through the rear shell 223 and the base 221 in sequence to connect and fix with the fixed base 1, thereby improving the stability of the base 221 after being connected with the fixed base 1. The rear shell 223 is also provided with a second fastener, which passes through the rear shell 223, the control circuit board 222, and the base 221 in sequence and is connected and fixed with the charging head 21 to avoid the possibility of the control circuit board 222 and the charging head 21 being disengaged. The control circuit board 222 is provided with an avoidance notch 2223 for avoiding the magnetic member 4. While avoiding the magnetic member 4, the magnetic member 4 is fixed in position to block the rotation of the control circuit board 222, thereby preventing the control circuit board 222 from rotating.

[0061] In this embodiment, if Figure 2 and Figure 8 As shown, a receiving cavity 224 for receiving components on the control circuit board 222 is provided on one side of the rear shell 223 facing the base 221, and the rear shell 223 abuts the control circuit board 222 on the side of the base 221 facing the rear shell 223 to stabilize the control circuit board 222 in the axial direction.

[0062] In order to facilitate the electrical connection between the control circuit board 222 and the charging head 21, as shown in FIG.

When the charging seat 22 is connected to the charging head 21, the socket 215 is plugged into the plug-in connection hole 217 and guided by the guide surface of the guide ring 216 to prevent the socket 215 from deviating from the center of the plug-in connection hole 217 and affecting the connection between the charging head 21 and the charging seat 22.

[0063] like Figure 8 and Fig. 9 As shown, the pin 2221 is formed by a plurality of elastic strips 2222 distributed circumferentially. When the pin 2221 is inserted into the plug-in connection hole 217 , the plurality of elastic strips 2222 are appropriately deformed and abut against the hole wall of the plug-in connection hole 217 to improve the stability of the plug-in connection between the pin 2221 and the socket 215 .

[0076] In order to improve the stability of the connection between the charging base 22, the fixing base 1 and the charging head 21, as shown in FIG. Figure 8As shown, the charging base 22 includes a base 221, a rear shell 223, and a control circuit board 222 sandwiched between the two.

[0077] In order to facilitate the electrical connection between the control circuit board 222 and the charging head 21, as shown in FIG. Figure 7 As shown, the charging head 21 is provided with a socket 215 and a primary induction coil 214 for inductively charging the component to be charged, the socket 215 is electrically connected to the primary induction coil 214, and the control circuit board 222 is provided with a pin 2221, and the pin 2221 is electrically connected to the socket 215 to realize the electrical connection between the control circuit board 222 and the primary induction coil 214.

[0078] Seventh embodiment:

[0079] like Figure 1 As shown, the present invention provides a wireless charging structure, including a fixing base 1 and a charger 2, wherein the fixing base 1 is used to be fixedly connected to a panel 3 to be installed. Figure 2 As shown, the charger 2 includes a charging head 21 exposed outside the fixing base 1 and a charging base 22 hidden inside the fixing base 1 . The charging head 21 is embedded in the fixing base 1 and electrically connected to the charging base 22 .

[0080] To prevent the charging stand 22 from deviating from the installation position during installation, Figure 4 and Figure 5 As shown, a cavity 12 is provided on the inner side of the fixing seat 1, and an anti-slip pad 121 is provided in the cavity 12.

During the installation of the charging seat 22, the anti-slip pad 121 is accommodated in the groove 2212 to prevent the charging seat 22 from moving relative to the fixing seat 1.

[0081] like Figure 3As shown, a magnetic attraction component 4 for adsorbing the component to be charged is provided in the charging seat 22. The charging seat 22 is connected to the fixing seat 1 and is restricted from rotating during the installation process, so that the position of the magnetic attraction component 4 remains fixed during the installation process.

[0082] In order to limit the rotation of the charging seat 22, multiple anti-skid pads 121 and grooves 2212 are arranged along the circumference of the charging seat 22. The multiple grooves 2212 are plugged into the anti-skid pads 121 to limit the rotation of the charging seat 22 relative to the fixed seat 1, thereby preventing the position of the magnetic element 4 from changing during the installation process. The anti-skid pads 121 also reduce the impact between the charging seat 22 and the fixed seat 1 due to vibration, thereby preventing damage to the charging seat 22.

[0083] Eighth embodiment:

[0084] The difference between this embodiment and the first embodiment is only in the installation method of the fixing base 1. Figure 2 As shown, in the present embodiment, in order to facilitate the disassembly of the fixing base 1, the fixing base 1 is adhered to the inner side surface of the panel 3 by an adhesive, wherein the adhesive may be a double-sided tape, an adhesive tape or glue, etc., and the corresponding adhesive may be selected according to the disassembly frequency of the fixing base 1, so as to facilitate the disassembly efficiency of the fixing base 1 when it is necessary to disassemble the fixing base 1, and facilitate the repair or replacement of the wireless charging structure.

[0085] In order to facilitate the wireless charging structure to charge the charging component, such as Figure 2 and Figure 3 As shown, the panel 3 is provided with a mounting hole 31, and the mounting hole 31 connects the inner and outer sides of the panel 3. The charging head 21 includes a charging head body and a cover body. The charging head body is embedded in the mounting hole 31 and is recessed inwardly relative to the outer side of the panel 3. The cover body is located at the front end of the charging head body. The cover body is assembled in the mounting hole 31 and fits circumferentially with the hole wall of the mounting hole 31 to block the mounting hole 31. The "fit" in this embodiment is not limited to the situation where the two are completely close. Considering the influencing factors such as processing accuracy and assembly accuracy, there may be a small gap between the outer peripheral side wall of the cover body and the hole wall of the mounting hole 31. Of course, these gaps are still visually difficult to see with the naked eye. When the outer peripheral side wall of the cover body and the hole wall of the mounting hole 31 are interference fit, the outer peripheral side wall of the cover body and the hole wall of the mounting hole 31 can basically be completely close, which can not only weaken the assembly traces of the mounting hole 31 and the charging head 21, but also have a certain waterproof effect.

[0086] Ninth embodiment:

[0088] In this embodiment, the controller 5 communicates with the electrical appliance body through the wireless charging structure. Specifically, the wireless charging structure is communicatively connected with the electrical appliance body. After the controller 5 is adsorbed on the panel 3 by the magnetic suction component 4, the controller 5 is communicatively connected with the wireless charging structure, thereby realizing the communication connection between the controller 5 and the electrical appliance body. The wireless charging structure can realize wireless charging and can also be used as a communication component, thereby increasing the function of the wireless charging structure and simplifying the overall structure of the appliance.

[0089] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes.
