[0002] With the development of knob technology, more and more household appliances are using knob controls. Users can operate and control household appliances by rotating knobs and buttons. To improve user experience, knobs can be fixed to the household appliance or removed and used as remote controls. However, in either case, the battery in the knob will gradually consume power during use. When the battery is exhausted, the battery needs to be replaced or recharged before the knob can resume function. To facilitate charging the battery of the knob, a charging mechanism is provided on the panel of the household appliance. To facilitate the removal of the knob for use as a remote control, the charging mechanism uses a wireless charging mode.

This enables wireless charging of the detachable control device 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 operating surface, and the control device is firmly adsorbed on the main body of the electrical appliance through the adsorption effect of the magnet.

[0005] The purpose of the present invention is to provide a wireless charging structure to solve the problem of the magnet deviating from the predetermined installation orientation during installation, so that the position of the magnetic attraction component remains fixed during installation.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a wireless charging structure, including a fixing base and a charger, the fixing base is used to be fixedly connected to the panel to be installed, the charger includes a charging head exposed on the outside of the fixing base and a charging base hidden on the inside of the fixing base, the charging head is embedded in the fixing base and electrically connected to the charging base, and a magnetic suction component is provided in the charging base for absorbing the component to be charged. The charging base is connected to the fixing base and is restricted from rotating during the installation process, so that the position of the magnetic suction component remains unchanged during the installation process.

[0007] After adopting the above technical solution, the utility model has the following advantages: when the wireless charging structure is installed, the charging base carrying the magnetic component is hidden and installed on the inner side of the fixed base, and the charging head is embedded in the outer side of the fixed base, so that the charging head is stably installed, and the rotation of the charging base is limited by the connection between the charging base and the fixed base, and then the fixed base is fixedly installed on the panel, so that the position of the magnetic component on the charging base relative to the panel does not change. When the component to be charged needs to be charged, the component to be charged is close to the panel and the component to be charged is adsorbed on the panel by the magnetic component. Under the adsorption effect of the magnetic component and the fixed position of the magnetic component, the orientation of the component to be charged after adsorption is unique. 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, which affects the user's experience.

[0008] Furthermore, one of the inner side of the fixing seat and the side of the charging seat facing the fixing seat is provided with a first anti-rotation structure, and the other is provided with a second anti-rotation structure. The first anti-rotation structure cooperates with the second anti-rotation structure to limit the rotation of the charging seat.

[0009] By adopting the above-mentioned technical solution, when the charging base is connected to the fixed base, the first anti-rotation structure cooperates with the second anti-rotation structure to prevent the charging base from rotating relative to the fixed base during the installation process, so that the magnetic suction component is fixed in the position of the charging base relative to the panel, and the magnetic suction component is prevented from rotating and inverting with the charging base, and the component to be charged is adsorbed on the panel and then inverted or deflected and tilted under the action of the magnetic force.

[0010] Furthermore, the first anti-rotation structure is an anti-rotation column, which extends in the front-to-back direction. The second anti-rotation structure is a positioning hole, and the anti-rotation column is inserted into the positioning hole to cooperate in limiting the rotation of the charging stand.

[0011] By adopting the above-mentioned technical solution, when the first anti-rotation structure is connected to the second anti-rotation structure, the anti-rotation column is inserted into the positioning hole, thereby preventing the charging base from rotating on the fixed base, and thereby preventing the charging base from driving the magnetic suction part to deviate from the preset installation orientation and causing the component to be charged to be inverted or deflected.

[0012] Furthermore, the anti-rotation column is provided with a first screw hole, and the first screw is connected with the first screw hole of the anti-rotation column along the front-to-back direction to fix the charging base and the fixing base.

[0013] By adopting the above-mentioned technical solution, after the anti-rotation column is inserted into the positioning hole, the first screw passes through the charging base to position the charging base axially on the anti-rotation column, or the first screw passes through the fixing base to position the fixing base and the charging base axially, while stopping the charging base from rotating circumferentially, the charging base is positioned axially to avoid the possibility of the charging base detaching from the anti-rotation column in the axial direction.

[0014] Furthermore, the first anti-rotation structure is an anti-rotation rib, and the second anti-rotation structure is an anti-rotation groove. The anti-rotation rib and the anti-rotation groove cooperate to limit the rotation of the charging stand.

[0015] By adopting the above-mentioned technical solution, when the charging base is connected to the fixed base, the anti-rotation rib is inserted into the anti-rotation groove. The anti-rotation effect of the anti-rotation rib and the anti-rotation groove prevents the charging base from driving the magnetic suction component to rotate relative to the fixed base, causing the magnetic suction component to deviate from the installation orientation.

[0016] Furthermore, the anti-rotation rib is a anti-return buckle, which extends from the back to the front. The two side edges of the anti-return buckle in the extension direction are fitted with the inner wall of the anti-rotation groove to limit the rotation of the charging stand.

[0017] By adopting the above-mentioned technical solution, the non-return buckle moves to the position of the non-rotation groove as the charging base is connected to the charging head, and the non-return buckle fits with the inner wall of the non-rotation groove in the radial direction of the charging base, thereby limiting the rotation of the charging base, so that the position of the magnetic suction part remains fixed so that the position of the component to be charged does not deflect when the component to be charged is magnetically attracted.

[0018] Furthermore, a positioning boss is provided on the inner side of the fixing seat, and a first receiving groove that cooperates with the positioning boss is provided on the side of the charging seat facing the fixing seat. One of the outer peripheral side surface of the positioning boss and the inner side surface of the first receiving groove is provided with a first anti-rotation structure, and the other is provided with a second anti-rotation structure.

[0019] By adopting the above-mentioned technical solution, when the charging base is connected to the fixed base, the first receiving groove on the charging base is sleeved on the positioning boss on the inner side of the fixed base to preliminarily position the charging base, and then the charging base is stopped from rotating by the cooperation of the first anti-rotation structure and the second anti-rotation structure to prevent the magnetic suction component from rotating with the charging base and affecting the adsorption and fixation of the magnetic suction component on the component to be charged.

[0020] Furthermore, the fixing seat is provided with a non-circular plug hole, and the charging seat is provided with a plug slot on the side facing the fixing seat. The charging head passes through the plug hole and cooperates with the plug slot. The charging head is adapted to the plug hole and the plug slot cross-section to limit the rotation of the charging seat.

[0021] Using the above-mentioned technical solution, when the charging head is connected to the fixed base, the charging head passes through the plug hole and extends into the plug slot of the charging base. The plug hole is set to be non-circular, and the connecting part of the charging head fits with the hole wall of the plug hole and the slot wall of the plug slot to prevent the charging base from rotating relative to the charging head, thereby ensuring that the magnetic suction part is fixed in position during the installation process.

[0022] Furthermore, the charging head includes a first base body and a second base body protruding toward the charging base relative to the first base body. The cross-section of the outer wall of the second base body is non-circular, and the second base body cooperates with the plug-in slot after passing through the plug-in hole.

[0023] By adopting the above-mentioned technical solution, when the charging head is connected to the charging base, the second base body passes through the plug-in hole and is connected to the plug-in slot. The outer peripheral side wall of the second base body cooperates with the hole wall of the plug-in hole and the slot wall of the plug-in slot, so that the charging base and the charging head are fixed in the circumferential direction, thereby preventing the charging base from rotating relative to the charging head and causing the component to be charged to move and affecting the orientation of the component to be charged.

[0024] Furthermore, a second screw hole is provided on the rear end face of the charging head. The second screw passes through the charging base and cooperates with the second screw hole to fix the charging head to the charging base and clamp the fixing base.

[0025] By adopting the above-mentioned technical solution, after the charging head, the fixing seat and the charging seat are circumferentially connected, the second screw passes through the charging seat and the fixing seat and is connected to the second screw hole on the charging head, thereby connecting the charging head and the charging seat in the axial direction, and the fixing seat is clamped between the charging head and the charging seat to fasten the charging head and the charging seat to the fixing seat, thereby avoiding the possibility of the charging head and the charging seat being detached, and ensuring that the position of the magnetic suction component is fixed.

[0026] Furthermore, the charging stand includes a base and a back shell, and a control circuit board sandwiched between the two. The base is connected to the fixed base, the back shell cover is arranged on the rear side of the base, the magnetic part is clamped and fixed by the base and the back shell, the first fastener passes through the back shell, the base and the fixed base in sequence, and the second fastener passes through the back shell, the control circuit board, the base and the charging head in sequence.

The second fastener passes through the rear shell, the control circuit board, and the base in sequence and is connected and fixed to the charging head, thereby fixing the charging base and the charging head to avoid the possibility of disengagement between the charging base and the charging head, and between the charging base and the fixed base, thereby improving the stability of the charging base and the magnetic suction component.

[0028] Furthermore, the charging head is provided with a primary induction coil for inductively charging the component to be charged, the charging head is electrically connected to the primary induction coil, one of the control circuit board and the charging head is provided with a socket, and the other is provided with a pin, and the pin is electrically connected to the socket.

[0029] By adopting the above-mentioned technical solution, when the charging base is connected to the charging head, the pins on the control circuit board are connected to the sockets on the charging head to realize the electrical connection between the primary induction coil and the control circuit board, so as to facilitate the primary induction coil to inductively charge the component to be charged.

[0030] Furthermore, a cavity is provided on the rear side of the fixing seat, and an anti-slip pad is provided in the cavity. A groove for accommodating the anti-slip pad is provided on the side of the charging seat facing the anti-slip pad. The charging seat rotation stop is provided behind the fixing seat and clamps the anti-slip pad with the fixing seat.

[0031] Using the above-mentioned technical solution, when the charging base is installed on the fixed base, the anti-slip pad in the concave cavity on the rear side of the fixed base extends into the groove of the charging base to initially position the charging base on the fixed base in the circumferential direction of the charging base to prevent the charging base from rotating during the installation process. The fixed base and the charging base clamp the anti-slip pad, and the anti-slip pad reduces the impact between the charging base and the fixed base during vibration to avoid damage to the wireless charging structure.

[0032] Furthermore, the fixing seat is adhered to the inner side of the panel by adhesive; or the fixing seat is welded to the inner side of the panel.

[0033] With the above technical solution, when installing the fixing base, the fixing base is adhered to the panel with adhesive, which facilitates the fixing and removal of the fixing base so as to facilitate the replacement of the wireless charging structure.

[0034] Furthermore, the charging head includes a charging head body and a cover body. The panel is provided with a mounting hole. The front end of the charging head body is embedded in the mounting hole and is recessed inward relative to the outer surface of the panel.

[0053] The following specific embodiments are used to describe the technical solution of the present invention in detail. 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 utility model 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 2As shown, the charger 2 includes a charging head 21 exposed on the outside of 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 removably fixed to the inner side of the panel 3 by screws.

[0056] like Figure 3 As shown, a magnetic member 4 is installed in the charging base 22. In this embodiment, a plurality of magnetic members 4 are installed in the charging base 22. The magnetic members 4 attract the component to be charged to fix the component to be charged. At this time, the distribution orientation of the plurality of magnetic members 4 is a predetermined installation orientation. If the magnetic members 4 rotate a certain angle with the charging base 22, causing the plurality of magnetic 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 members 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 base 22 is connected to the fixing base 1 and needs to be restricted from rotating during the installation process, so that the distribution orientation of the plurality of magnetic members 4 remains unchanged 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 member 4 attracts the component to be charged, causing the displayed information to be inverted or tilted.

[0057] Specifically, such as Figure 3 and Figure 4 As shown, a first anti-rotation structure is provided on the inner side of the fixing base 1. The first anti-rotation structure is an anti-rotation column 11. The anti-rotation column 11 extends from front to rear. A second anti-rotation structure is provided on the side of the charging base 22 facing the fixing base 1. The second anti-rotation structure is a positioning hole 2211. When the charging base 22 is connected to the fixing 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 the 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 this 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 component 4 is distributed in a predetermined position so that the magnetic 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 post 11 is provided with a first screw hole 111, and a first screw is provided between the charging base 22 and the anti-rotation post 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 post 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 this embodiment, as Figure 5 As shown, the first anti-rotation structure can also be on the side of the charging base 22 facing the fixed base 1. The first anti-rotation structure is the anti-rotation column 11. At this time, the anti-rotation column 11 extends from the back to the front. 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 the 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 base 22 facing the fixed base 1 is provided with an insertion groove 2213 and a first receiving groove 2214. The first receiving groove 2214 is on the side of the charging base 22 facing the fixed base 1. A contact surface 2215 is formed between the first receiving groove 2214 and the insertion groove 2213. After the charging base 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 7As 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 inserted 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. Figure 8 As shown, the charging stand 22 includes a base 221, a rear shell 223, and a control circuit board 222 sandwiched between the two. 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 element 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, the base 221, and the fixed base 1 in sequence to connect and fix, thereby improving the stability of the base 221 after being connected to 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 to connect and fix, thereby preventing the control circuit board 222 from being disconnected from the charging head 21. The control circuit board 222 is provided with an avoidance notch 2223 to avoid the magnetic element 4. While avoiding the magnetic element 4, the magnetic element 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 the 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. Figure 8 and Figure 9 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. The control circuit board 222 is provided with a pin 2221, which is electrically connected to the socket 215 to realize the electrical connection between the control circuit board 222 and the primary induction coil 214. Specifically, as Figure 7 and Figure 9As shown, the socket 215 is provided with a plug-in connection hole 217 on the side facing the plug pin 2221, and the plug pin 2221 is plugged into the plug-in connection hole 217 to realize the electrical connection between the primary induction coil 214 and the control circuit board 222; in order to facilitate the plugging of the plug pin 2221 into the plug-in connection hole 217, the socket 215 is provided with a guide ring 216 on the side facing the plug pin 2221, and the inner arc surface of the guide ring 216 is a guide surface and is connected to the inner side wall of the plug-in connection hole 217. The pin 2221 is guided by the guide surface and accurately plugged into the plug-in connection hole 217. 17; in another embodiment, a plug-in connection hole 217 is provided on the side of the pin 2221 facing the socket 215, and a guide ring 216 is provided on the side of the pin 2221 facing the socket 215. The inner ring surface of the guide ring 216 is a guide surface and is connected to the inner side of the plug-in connection hole 217. 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 is 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 Figure 9 As shown, the pin 2221 is formed by multiple elastic strips 2222 distributed circumferentially. When the pin 2221 is inserted into the plug-in connection hole 21, the multiple 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 connection between the pin 2221 and the socket 215.

[0064] In this embodiment, if 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. A groove 2212 for accommodating the anti-slip pad 121 is provided on the side of the charging seat 22 facing the anti-slip pad 121. The charging seat 22 is arranged on the fixing seat 1 and clamps the anti-slip pad 121 with the fixing seat 1, wherein multiple anti-slip pads 121 and grooves 2212 are distributed circumferentially. The rotation of the charging seat 22 is restricted by the insertion of multiple anti-slip pads 121 into the grooves 2212. At the same time, the anti-slip pad 121 also reduces the impact between the charging seat 22 and the fixing seat 1 due to vibration, thereby avoiding damage to the charging seat 22.

[0078] Seventh embodiment:

[0079] like Figure 1 As shown, the utility model 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 station 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 base 1, and an anti-slip pad 121 is provided in the cavity 12.

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

[0082] To limit the rotation of the charging base 22, multiple anti-slip blocks 121 and grooves 2212 are provided along the circumference of the charging base 22.

The anti-slip blocks 121 also mitigate vibration-induced impacts between the charging base 22 and the fixed base 1, preventing damage to the charging base 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, such as Figure 2 As shown, in this embodiment, in order to facilitate the disassembly of the fixing base 1, the fixing base 1 is adhered to the inner surface of the panel 3 by an adhesive, wherein the adhesive can be a double-sided tape, adhesive tape or glue, etc. The corresponding adhesive can 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 maintenance or replacement of the wireless charging structure.

[0085] In order to facilitate the wireless charging structure to charge the charging components, such as Figure 2 and Figure 3 As shown, the panel 3 is provided with a mounting hole 31, which 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 surface 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 seal the mounting hole 31. The "fit" in this embodiment is not limited to the situation where the two are completely close together. Considering 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 can basically be completely close to the hole wall of the mounting hole 31, 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:

[0087] like Figure 10As shown, the present invention also provides an electrical appliance, including an electrical appliance main body and a controller 5, the controller 5 and the electrical appliance main body are communicatively connected with each other, the electrical appliance main body has a panel 3, and the panel 3 has a wireless charging structure as in the above embodiment, the controller 5 is adsorbed on the panel 3 through a magnetic suction part 4, and the controller 5 is matched with the wireless charging structure to obtain wireless charging, so that the controller 5 is charged on the electrical appliance, avoiding the controller 5 from being lost after being disassembled and charged.

[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 to the electrical appliance body. After the controller 5 is adsorbed on the panel 3 by the magnetic component 4, the controller 5 is communicatively connected to the wireless charging structure, thereby realizing the communication connection between the controller 5 and the electrical appliance body.
