Technical Field
[0001] The utility model relates to the technical field of household appliances, in particular to an appliance. Background Art
[0002] With the advancement of technology, more and more electrical appliances are being used in homes. As people continue to use appliances, the demand for smarter, more intelligent appliances is growing, particularly for wireless control. Consequently, more and more knobs are being used as removable remote controls. During use, the batteries in these knobs gradually deplete. When the batteries are depleted, they must be replaced or recharged before the knobs can function again. To facilitate battery charging in knobs, wireless charging mechanisms are now being incorporated into the front panels of household appliances.
[0003] Prior art CN217935588U discloses a household appliance comprising an appliance body, the appliance body comprising a metal panel and a detachable control device, the detachable control device wirelessly communicating with the appliance body, wherein a key is embedded in the panel, the key having an operating surface supported by a non-conductive material, a primary induction coil integrated on the back side of the operating surface, and a secondary induction coil integrated in the detachable control device, so that the detachable control device can be charged by electromagnetic induction when the detachable control device covers the key. 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 install the wireless charging structure and facilitate inductive charging of the wireless charging structure, a corresponding mounting hole is opened on the panel, and then a button is embedded in the mounting hole to cover the mounting hole to prevent the opened mounting hole from affecting the appearance of the metal panel. When the control device is charging or adsorbed on the panel, the control device covers the mounting hole, but when the control device is detached from the panel, there is still a gap between the button and the hole wall of the mounting hole, affecting the appearance of the metal panel. Utility Model Content
[0005] The purpose of the present invention is to provide an electrical appliance that solves the problem of a gap between the mounting hole and the button on the panel, and visually weakens the assembly traces between the mounting hole and the charging head.
[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an electrical appliance, including an electrical appliance main body and a controller, the controller and the electrical appliance main body communicate with each other, the electrical appliance main body has a panel, the panel is provided with a mounting hole and a wireless charging device installed at the mounting hole, the wireless charging device includes a charging head and a charging base, the charging head is provided with a primary induction coil for induction charging, the charging base is provided with a control circuit board, the primary induction coil is electrically connected to the control circuit board, the charging head is embedded in the mounting hole from the outside of the panel and then connected to the charging base, or the charging head is embedded in the mounting hole from the inside of the panel after being connected to the charging base, and the outer peripheral side wall of the charging head is fitted with the hole wall of the mounting hole to seal the mounting hole.
[0007] After adopting the above technical solution, the present invention has the following advantages: to facilitate the removal and charging of the controller, a mounting hole is opened on the panel, and the wireless charging device is installed on the inner side of the panel and located at the mounting hole, thereby reducing the impact of the panel on the charging efficiency of the wireless charging device. The opening is blocked by the charging head, thereby reducing the impact of the opening on the appearance of the panel. When installing the wireless charging device, one method is to first install the charging base on the back of the panel, and then embed the charging head in the mounting hole and connect it to the charging base; the other method is to connect the charging head to the charging base and then embed the wireless charging device in the mounting hole. However, in either of the above two installation methods, the outer peripheral side wall of the charging head needs to be aligned with the hole wall of the mounting hole to block the mounting hole on the panel. Among them, the charging head is embedded in the mounting hole of the panel. To ensure the stability of the electrical connection between the charging head and the charging base, the charging head is generally fixed after installation. There is no need to reserve a reserved space between the mounting hole and the button when operating the button as in the prior art. The outer peripheral surface of the charging head is as close to the hole wall of the mounting hole as possible, thereby visually weakening the assembly traces of the mounting hole and the charging head. The "fit" here 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 side wall of the charging head and the wall of the mounting hole. Of course, these gaps are still not as visually obvious as the gaps in the existing technology. When the outer side wall of the charging head and the wall of the mounting hole are interference fit, the outer side wall of the charging head and the wall of the mounting hole can basically be completely close together, which can not only weaken the assembly traces of the mounting hole and the charging head, but also have a certain waterproof effect.
[0008] Furthermore, the charging head includes a charging head body and a cover body, the rear end of the charging head body is connected to the charging seat and is recessed inward relative to the outer side of the panel, the cover body is located at the front end of the charging head body, the cover body is assembled in the mounting hole and is circumferentially fitted with the hole wall of the mounting hole to seal the mounting hole, and the edge of the outer side surface of the cover body is flush with the outer side surface of the panel; or, the charging head includes a charging head body, the rear end of the charging head body is connected to the charging seat, the front end of the charging head body is circumferentially fitted with the hole wall of the mounting hole to seal the mounting hole, and the edge of the front end surface of the charging head body is flush with the outer side surface of the panel.
[0009] With the aforementioned technical solution, when the outer peripheral side wall of the charging head fits against the wall of the mounting hole, the outer peripheral side wall of the cover fits against the wall of the mounting hole, and the outer side surface of the cover is flush with the outer side surface of the panel, thereby weakening the installation traces of the mounting hole and the charging head. When there is an interference fit between the mounting hole and the charging head, the outer peripheral side wall of the charging head will deform to a certain extent after the charging head is installed. The cover fits with the mounting hole to prevent the primary induction coil from being affected by the deformation of the charging head body. Alternatively, the rear end of the charging head body is connected to the charging base, and the front end of the charging head body fits circumferentially against the wall of the mounting hole to block the mounting hole, thereby visually weakening the assembly traces of the charging head and the mounting hole. The edge of the front end surface of the charging head body is flush with the outer side surface of the panel, further weakening the installation traces of the mounting hole and the charging head.
[0010] Furthermore, the rear end of the charging head is fixed to the charging base, and the charging base is installed from back to front and fixed to the inner side of the panel; or, the charging head is installed from front to back and connected and fixed to the charging base located on the inner side of the panel.
[0011] Using the above-mentioned technical solution, when the charging base and the charging head are installed, the charging base is fixed to the rear end of the charging head, and then the charging base is fixed to the inner side of the panel, and then the charging head and the charging base are fixed on the panel to avoid the possibility of the charging head and the charging base being disengaged, and at the same time avoid the possibility of the charging head and the charging base being separated from the panel; or the charging base is fixed to the inner side of the panel, and the charging head is fixed to the charging base from front to back and clamps the panel with the charging base to improve the stability of the charging base and the charging head after installation.
[0012] Furthermore, a fixing seat is sandwiched between the charging head and the charging base, and the fixing seat is fixed to the inner side of the panel. The fixing seat is provided with a limiting hole with a non-circular cross-section, and the rear end of the charging head cooperates with the limiting hole to achieve anti-rotation.
[0013] Using the above-mentioned technical solution, when installing the charging head and the charging base, the charging base is installed on the inside of the fixed base, and the charging head is installed on the outside of the fixed base. The fixed connection between the fixed base and the inner side of the panel facilitates the stable installation of the charging head and the charging base. The non-circular limiting holes on the charging head and the fixed base cooperate to prevent the charging head from rotating relative to the fixed base so that the charging head cannot be well connected to the charging base, thereby preventing the connection between the charging head and the charging base from affecting the electrical connection between the primary induction coil and the control circuit board.
[0014] Furthermore, the limiting hole is a through hole that passes through the fixing seat, the charging head is electrically connected to the primary induction coil, one of the charging head and the control circuit board is provided with a first socket and a second socket, and the other is provided with a first pin and a second pin, and the first socket and the second socket are respectively connected with the first pin and the second pin using the limiting hole.
[0015] By adopting the above-mentioned technical solution, the connection between the control circuit board and the primary induction coil is realized through the first socket and the second socket and the first pin and the second pin to realize electrical connection, which facilitates the primary induction coil and the control circuit board to be energized to realize inductive charging. The first pin and the second pin are connected to the second socket and the second socket respectively through the limiting hole to avoid the first pin, the second pin, the second socket and the second socket from abutting against the physical structure and affecting the electrical connection, thereby facilitating the connection between the control circuit board and the primary induction coil.
[0016] Furthermore, the first socket and the second socket are provided with plug holes, and the first plug pin and the second plug pin are correspondingly inserted into the plug holes to cooperate and realize electrical connection.
[0017] By adopting the above technical solution, when the first pin is connected to the first socket and the second pin is connected to the second socket, they are inserted into the plug hole, which improves the stability of the connection between the pin and the socket and avoids the possibility of the pin being detached from the socket and affecting the electrical connection.
[0018] Furthermore, the charging seat is provided with a pin base and a first placement hole that cooperates with the outer wall of the pin base on the side facing the charging head, and the first pin and the second pin are supported by passing through the pin base.
[0019] Using the above-mentioned technical solution, the first pin and the second pin extend on the control circuit board toward the charging head, and pass through the pin base to obtain support during the extension process, thereby avoiding the possibility of the first pin and the second pin being bent or broken due to vibration.
[0020] Furthermore, the side of the charging head facing the charging seat is provided with a socket base and a second placement hole that matches the outer peripheral wall of the socket base, and the first socket and the second socket are supported by the socket base.
[0021] Using the above technical solution, the socket base is placed in conjunction with the second placement hole, and the socket is plugged into the socket base to support the socket, thereby preventing the socket from bending or breaking during the vibration of the appliance, and facilitating the plug-in connection between the pin and the socket.
[0022] Furthermore, a fool-proof plug-in slot is provided on the side of the charging base facing the charging head, and the charging head is plugged into the plug-in slot to achieve fool-proof installation of the charging head relative to the charging base.
[0023] By adopting the above-mentioned technical solution, the charging head is plugged into the anti-mistaken plug-in slot on the side facing the charging base, so that the charging head and the charging base can be installed in an anti-mistaken manner, thereby preventing the charging head from being deflected from the installation orientation and connected to the charging base, and further avoiding the first pin and the first socket, and the second pin and the second socket from being misaligned when plugged in, thereby affecting the charging function of wireless charging.
[0024] Furthermore, a fixed base is sandwiched between the charging head and the charging base, and the fixed base is fixed to the inner side of the panel. The charging head includes a first base body and a second base body located at the rear end of the first base body. A receiving groove is provided on the side of the fixed base facing the charging head. The first base body cooperates with the receiving groove, and the second base body passes through the fixed base and cooperates with the plug-in slot.
[0025] By adopting the above-mentioned technical solution, the charging head is set into a first seat body and a second seat body. When the charging head is installed, the first seat body is embedded in the accommodating groove, and the second seat body extends into the plug-in groove after passing through the fixed seat. The groove wall of the anti-fouling plug-in groove cooperates with the outer peripheral wall of the second seat body to prevent the corresponding positions of the first pin and the second pin from being deflected when plugging into the first socket and the second socket respectively during the installation process of the charging seat and the charging head.
[0026] Furthermore, the charging seat is provided with a mounting groove connected to the plug-in groove on one side of the fixing seat, and abutment surface is formed at the connection between the mounting groove and the plug-in groove. The rear side surface of the fixing seat is provided with a connecting boss protruding backward, and the accommodating groove is located in the connecting boss. After the connecting boss is inserted into the mounting groove, it abuts against the abutment surface, and the outer peripheral wall of the connecting boss is in contact with the wall of the mounting groove.
[0027] With the aforementioned technical solution, when the charging base is installed on the inner side of the fixed base, the connecting boss is inserted into the mounting groove, and the connecting boss abuts against the abutting surface on the side facing the charging base, thereby preventing the connecting boss from being fully inserted into the mounting groove and causing the charging base to axially disengage from the connecting boss, thereby improving the stability of the charging base. When the charging head is installed, the charging head passes through the connecting boss in the accommodating groove, so that the charging head is embedded in the connecting boss, reducing the length of the charging head protruding from the outer side of the fixed base, making it easier for the fixed base to be fixed on the inner side of the panel.
[0028] Furthermore, a positioning column is provided on a side of the fixing seat facing the charging seat, and a positioning hole is provided on a side of the charging seat facing the fixing seat, and the positioning column cooperates with the positioning hole.
[0029] Using the above-mentioned technical solution, when the charging base is installed on the inner side of the fixed base, the positioning column on the fixed base is inserted into the positioning hole on the charging base to position the charging base in the circumferential direction, thereby preventing the charging base from rotating relative to the fixed base, causing the charging head to be unable to be properly inserted into the socket, thereby affecting the fool-proof installation between the charging head and the charging base.
[0030] Furthermore, the primary induction coil is arranged on the induction circuit board, the induction circuit board is fixed to the charging head, the charging base includes a base and a back cover, the control circuit board is clamped by the base and the back cover, the first fastener passes through the back cover, the control circuit board, the base and the charging head in sequence and is fastened to the induction circuit board, and the second fastener passes through the back cover and the base in sequence and is fastened to the fixed base to clamp the control circuit board and the base.
[0031] Using the above-mentioned technical solution, the control circuit board is placed between the base and the back cover and is fastened together by a first fastener. The base, the back cover and the control circuit board are then fastened together on the inner side of the fixing base by a second fastener to prevent the base, the back cover or the control circuit board from moving relative to the fixing base and affecting the inductive charging. When the charging head is charging, it is connected to the control circuit board through the inductive circuit board, which facilitates inductive charging after the primary inductive coil is energized.
[0032] Furthermore, a placement groove is provided on the side of the charging head facing away from the charging base, and a positioning groove and a positioning protrusion are provided on the bottom wall of the placement groove. The sensing circuit board is arranged in the positioning groove and plugged into the positioning protrusion to position the circuit board.
[0033] With the aforementioned technical solution, when the induction circuit board is installed on the charging head, the induction circuit board is accommodated in the placement groove and positioned by the positioning groove and the positioning protrusion, thereby preventing the induction circuit board from detaching from the charging head housing and affecting the normal use of the induction circuit board.
[0034] Furthermore, the charging head is provided with a heat conducting plate located between the induction circuit board and the primary induction coil, and the heat conducting plate is in contact with the charging head housing to conduct heat.
[0035] With the aforementioned technical solution, the induction circuit board and the primary induction coil generate heat when energized. By installing a heat conducting plate between the induction circuit board and the primary induction coil, the heat generated by the induction circuit board and the primary induction coil is transferred outward through the heat conducting plate to the back of the charging head housing, thereby preventing the induction circuit board and the primary induction coil from being overheated and affecting induction charging.
[0036] Furthermore, the side of the back cover facing the base is provided with a accommodating cavity for accommodating the control circuit board, the inner side wall of the accommodating cavity is provided with abutting ribs, the abutting ribs abut the control circuit board to cooperate with the base to clamp the control circuit board, and an accommodating space for accommodating components on the control circuit board is formed between the side of the control circuit board facing away from the base and the inner wall of the accommodating cavity.
[0037] By adopting the above-mentioned technical solution, the control circuit board is clamped by the base and the back cover, and a receiving cavity is provided on the side of the back cover facing the base, so that the components on the control circuit board are accommodated in the receiving cavity, and then abutted against the control circuit board through the abutting ribs. While stably installing the control circuit board, the back cover is prevented from abutting against the components on the control circuit board, thereby preventing damage to the components.

[0051] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

Even if "second" is used before a technical feature to distinguish it, it does not necessarily imply the presence of "first." It should be understood that in this utility model, "including," "having," and any variations thereof are intended to cover non-exclusive inclusions. It should be understood that in this utility model, "plurality" refers to two or more. "And / or" is merely a description of an association between related objects, indicating that three relationships can exist.

"Including X, Y, and / or Z" means that any one, any two, or any three of X, Y, and Z are included.
[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] like Figure 1 As shown, the utility model provides an electrical appliance, including an electrical appliance body 4 and a controller 5. The controller 5 and the electrical appliance body 4 are communicatively connected with each other. The electrical appliance body 4 has a panel 1. The panel 1 is provided with a mounting hole 11 and a wireless charging device 3 located at the mounting hole 11. The wireless charging device 3 installed on the panel 1 facilitates charging of the controller 5. The mounting hole 11 reduces the impact of the panel 1 on the charging efficiency of the controller 5.
[0055] like Figures 2 to 5 As shown, the wireless charging device 3 includes a charging head 31 and a charging base 32. The charging head 31 is provided with a primary induction coil 312 for inductive charging, and the charging base 32 is provided with a control circuit board 321. The primary induction coil 312 is electrically connected to the control circuit board 321. The charging head 31 is embedded in the mounting hole 11, and the charging base 32 is installed on the inner side of the panel 1 and connected to the charging head 31. The outer peripheral side wall of the charging head 31 is fitted with the hole wall of the mounting hole 11 to block the mounting hole 11, thereby reducing the impact of the mounting hole 11 on the appearance of the panel 1.
[0056] In the prior art, the metal appearance of the electrical appliance body is maintained by installing buttons. However, when using the buttons, the buttons need to have appropriate space reserved for pressing the buttons. Therefore, a certain space needs to be reserved between the buttons and the panel 1, resulting in obvious assembly marks between the buttons and the hole wall in terms of visual effects.
[0057] In this embodiment, if Figure 5 As shown, the charging head 31 includes a charging head body. When the charging head 31 is installed, the charging head body is inserted into the mounting hole 11 from the outside of the panel 1. The rear end of the charging head body is connected to the charging base 32. The front end of the charging head body is circumferentially aligned with the wall of the mounting hole 11 to block the mounting hole 11. The edge of the front end of the charging head body is flush with the outer side surface of the panel 1, thereby visually reducing the assembly traces between the mounting hole 11 and the charging head 31 and maintaining the appearance of the panel 1. In addition, the "alignment" mentioned in the present invention is not limited to a complete fit between the mounting hole 11 and the charging head 31. Taking into account factors such as processing accuracy and assembly accuracy, a small gap between the outer peripheral side wall of the charging head body and the wall of the mounting hole 11 is allowed. Of course, this gap is still less visually obvious than the gap in the prior art. Moreover, when the outer peripheral side wall of the charging head body and the wall of the mounting hole 11 form an interference fit, the outer peripheral side wall of the charging head 31 can basically be in close contact with the wall of the mounting hole 11, which not only reduces the assembly traces between the mounting hole 11 and the charging head 31, but also provides a certain waterproof effect. In addition, the charging head body and the mounting hole 11 are affected by the processing accuracy, and the cross-section of the outer peripheral side wall of the charging head 31 and the hole wall of the mounting hole 11 may not be a very standard circle. Therefore, the fit between the outer peripheral side wall of the charging head body in this embodiment and the hole wall of the mounting hole 11 may also be that a smaller part in the circumferential direction of the mounting hole 11 is not completely fitted while the rest of the larger part is completely fitted.
[0058] In another embodiment, in order to further cover the mounting hole 11, as shown in FIG. Figure 4 and Figure 5 As shown, the charging head 31 includes a charging head body and a cover body 311. The rear end of the charging head body is connected to the charging seat 32 and is recessed inward relative to the outer side of the panel 1. The cover body 311 is located at the front end of the charging head body 31. The cover body 311 is assembled in the mounting hole 11 and is circumferentially fitted with the hole wall of the mounting hole 11 to seal the mounting hole 11. The edge of the outer side surface of the cover body 311 is flush with the outer side surface of the panel 1. The charging head body is in the mounting hole 11 and recessed in the outer side surface of the panel 1, so that the edge of the outer side surface of the cover body 311 is flush with the outer side surface of the panel 1, weakening the installation traces of the mounting hole 11 and the charging head 31; when the mounting hole 11 and the charging head 31 are interference fit, the outer peripheral side wall of the charging head 31 will be deformed to a certain extent after the charging head 31 is installed. The cover body 311 cooperates with the mounting hole 11 to avoid a certain deformation of the charging head body 31 and deformation of the primary induction coil 312.
[0059] When installing the charging head 31 and the charging base 32, Figure 2 As shown, first assemble the charging head 31 and the charging base 32 together, then integrate the charging head 31 and the charging base 32 and install them on the inner side of the panel 1 from back to front. Figure 4 and Figure 5 As shown, the front end surface of the charging seat 32 abuts against the inner side of the panel 1 , and the charging head 31 is embedded in the mounting hole 11 so that the charging head 31 blocks the mounting hole 11 .
[0060] In another embodiment, the charging base 32 is fixed first, and then when the charging head 31 is installed from front to back, in order to ensure the stable connection between the charging base 32 and the charging head 31 and the stability after installation, Figure 4 and Figure 5 As shown, a fixing seat 2 is detachably provided on the inner side of the panel 1, and the fixing seat 2 can be detachably fixed by bolts or by gluing; the fixing seat 2 can also be fixed to the inner side of the panel 1 by welding; when installing the charging head 31 and the charging seat 32, first install the charging seat 32 on the inner side of the fixing seat 2 to prevent rotation, and then install the charging head 31 on the front side of the fixing seat 2 and clamp the fixing seat 2 with the charging seat 32. After the charging seat 32 is stopped, it is convenient for the charging head 31 to be stably connected to the charging seat 32, avoiding deflection and misalignment of the charging head 31 and the charging seat 32.
[0061] In another embodiment, if Figure 5 and Figure 6 As shown, the charging head 31 is provided with a first socket 3121 and a second socket 3122 connected to the primary induction coil 312. The control circuit board 321 is provided with a first pin 3211 and a second pin 3212. The first socket 3121 and the second socket 3122 are respectively the positive and negative electrodes of the primary induction coil 312, and the first pin 3211 and the second pin 3212 are respectively the positive and negative electrodes of the control circuit board 321. The first socket 3121 is electrically connected to the first pin 3211, and the second socket 3122 is electrically connected to the second pin 3212 to achieve inductive charging. In this embodiment, the first socket 3121 and the second socket 3122 can also be transmission pins for two different signals. The first pin 3211 and the second pin 3212 are transmission pins for two signals corresponding to the first socket 3121 and the second socket 3122. The first socket 3121 is electrically connected to the first pin 3211, and the second socket 3122 is electrically connected to the second pin 3212 to achieve signal transmission.
[0062] To facilitate the corresponding connection between the first socket 3121 and the first pin 3211, and the corresponding connection between the second socket 3122 and the second pin 3212, as shown in FIG. Figure 5As shown, a mounting through hole 21 is provided on the fixing base 2, and the cross-section of the mounting through hole 21 is non-circular. The charging head 31 is provided on the outside of the fixing base 2 and the inner side of the charging head 31 is embedded in the mounting through hole 21 and adapted to the hole wall of the mounting through hole 21, so that the first pin 3211 corresponds to the first socket 3121, and the second pin 3212 corresponds to the second socket 3122, thereby avoiding the possibility of misalignment between the first pin 3211 and the first socket 3121, and the second pin 3212 and the second socket 3122.
[0063] In this embodiment, if Figure 6 and Figure 7 As shown, the first socket 3121 and the second socket 3122 are provided with a plug hole 3125 on the side facing the charging base 32, and the first pin 3211 and the second pin 3212 respectively correspond to the plug holes 3125 of the first socket 3121 and the second socket 3122 to realize the electrical connection between the first pin 3211 and the first socket 3121; the first socket 3121 and the second socket 3122 are provided with a guide ring 3126 on the side facing the charging base 32, and the inner ring surface of the guide ring 3126 is a guide surface 3127. The first pin 3211 and the second pin 3212 are guided by the guide surface 3127 when they are plugged in, which facilitates the plugging and matching of the first pin 3211 and the second pin 3212 with the plug hole 3125 and avoids deviation from the plug hole 3125 during plugging.
[0064] To avoid the possibility of bending or breaking of the first pin 3211, the second pin 3212, the first socket 3121 and the second socket 3122, as shown in FIG. Figure 8 As shown, a socket base 3123 and a second placement hole 3124 adapted to the outer wall of the socket base 3123 are provided on the side of the charging head 31 facing the charging seat 32. The first socket 3121 and the second socket 3122 are plugged into the socket base 3123 to obtain support, thereby improving the stability of the first socket 3121 and the second socket 3122 and preventing the first socket 3121 and the second socket 3122 from bending or breaking; a pin base 3213 is provided on the side of the control circuit board 321 facing the charging head 31, and the charging seat 32 is provided with a first placement hole 3214 adapted to the outer wall of the pin base 3213. When the first pin 3211 and the second pin 3212 extend toward the charging head 31, they are plugged into the pin base 3213 to obtain support, thereby preventing the first pin 3211 and the second pin 3212 from bending or breaking.
[0065] In another embodiment, a first socket 3121 and a second socket 3122 may be provided on the control circuit board 321, and the charging head 31 may be provided with a first pin 3211 and a second pin 3212 connected to the primary induction coil 312, and the first socket 3121 and the second socket 3122 are plugged and connected to the first pin 3211 and the second pin 3212 respectively.
[0066] In another embodiment, if Figure 8 and Figure 9 As shown, the charging head 31 includes a first base body 313 and a second base body 314 that protrudes toward the charging base 32 relative to the first base body 313. The cross-section of the outer peripheral wall of the second base body 314 is non-circular. The side of the fixing base 2 facing the charging head 31 is provided with a receiving groove 221. The rear side surface of the fixing base 2 is provided with a connecting boss 22 that protrudes backward. The receiving groove 221 is located on the connecting boss 22, and the receiving groove 221 is coaxial with the connecting boss 22. The fixing base 2 is also provided with a mounting through hole 22 that connects the inside and outside of the fixing base 2. 1. The hole wall of the mounting through hole 21 is non-circular. The mounting through hole 21 is located on the connecting boss 22 and is connected to the receiving groove 221. When installing the charging head 31, the second base body 314 moves from the outside to the inside of the fixing base 2, so that the second base body 314 extends into the receiving groove 221 and then passes through the mounting through hole 21, so that the first base body 313 is embedded in the receiving groove 221. The non-circular cross-sections of the second base body 314 and the mounting through hole 21 are mutually adapted D-shaped, thereby preventing the charging head 31 from being fooled and installed on the fixing base 2.
[0067] like Figure 8 、 Figure 9 and Figure 10 As shown, the charging base 32 is provided with a foolproof insertion groove 3222 and a mounting groove 3223 on the side facing the fixed base 2. The mounting groove 3223 is located on the side of the charging base 32 near the fixed base 2, and the connection between the mounting groove 3223 and the insertion groove 3222 forms an abutment surface 3224. When installing the charging base 32, the charging base 32 is sleeved on the connecting boss 22 and slid axially until the connecting boss 22 abuts against the abutment surface 3224, thereby stably installing the charging base 32 in the axial direction. The outer peripheral sidewall of the connecting boss 22 abuts against the groove wall of the mounting groove 3223, thereby stabilizing the charging base 32 in the radial direction. When the connecting boss 22 abuts against the abutment surface 3224, the second base body 314 extends into the insertion groove 3222, and the outer peripheral sidewall of the second base body 314 abuts against the groove wall of the insertion groove 3222, thereby achieving foolproof installation of the charging base 32 and the charging head 31.
[0068] To facilitate the connection between the second base 314 and the plug-in slot 3222, Figure 9 and Figure 10As shown, a positioning post 23 is provided on the side of the fixing base 2 facing the charging base 32, and a positioning hole 3221 is provided on the side of the charging base 32 facing the fixing base 2. As the charging base 32 is connected to the connecting boss 22, the positioning post 23 is inserted into the positioning hole 3221 to limit the rotation of the charging base 32, thereby facilitating the insertion and mating of the second base body 314 with the insertion groove 3222, and the outer peripheral side wall of the second base body 314 is in contact with the groove wall of the insertion groove 3222. To improve the anti-rotation effect, multiple positioning posts 23 and positioning holes 3221 are distributed circumferentially, and multiple positioning posts 23 are inserted into multiple positioning holes 3221 in a one-to-one correspondence, thereby improving the anti-rotation effect of the charging base 32.
[0069] like Figure 9 and Figure 10 As shown, a concave cavity 24 is provided on the side of the fixing seat 2 facing the charging seat 32, and a non-slip pad 241 is provided on the bottom wall of the concave cavity 24. A groove 3225 is provided on the side of the charging seat 32 facing the fixing seat 2. After the charging seat 32 is sleeved on the connecting boss 22, the non-slip pad 241 is inserted into the groove 3225. The non-slip pad 241 reduces the possibility of sliding of the charging seat 32 during installation. There are multiple non-slip pads 241 and grooves 3225 distributed along the circumference of the charging seat 32, and multiple grooves 3225 are correspondingly plugged into multiple non-slip pads 241 to improve the anti-slip effect; the non-slip pad 241 reduces the impact force between the fixing seat 2 and the charging seat 32 during vibration, thereby avoiding damage to the charging seat 32 and the fixing seat 2 due to vibration.
[0070] In another embodiment, Figure 4 and Figure 5 As shown, the charging stand 32 includes a base 322 and a back cover 323. The back cover 323 is provided with a housing cavity 3231 for accommodating the control circuit board 321 on the side facing the base 322. The inner wall of the housing cavity 3231 is provided with abutting ribs 3232. The control circuit board 321 is clamped by the base 322 and the back cover 323, and the abutting ribs 3232 abut against the control circuit board 321 to cooperate with the base 322 to clamp the control circuit board 321. A housing space for accommodating components on the control circuit board 321 is formed between the side of the control circuit board 321 opposite to the base 322 and the inner wall of the housing cavity 3231, thereby preventing the components on the control circuit board 321 from being squeezed and damaged. Figure 5 and Figure 11As shown, an induction circuit board 3134 is provided in the charging head 31, and the primary induction coil 312 is provided on the induction circuit board 3134. A first fastener 324 and a second fastener 325 are provided on the back cover 323. The first fastener 324 passes through the back cover 323, the control circuit board 321, the base 322 and the charging head 31 in sequence and is fastened to the induction circuit board 3134 to prevent the charging base 32 from being detached from the charging head 31. The second fastener 325 passes through the back cover 323 and the base 322 in sequence and is tightly connected to the fixing base 2 to clamp the control circuit board 321 and the base 322 to prevent the charging base 32 from being detached from the fixing base 2.
[0071] In order to stably install the sensing circuit board 3134 on the charging head 31, as shown in FIG. Figure 5 and Figure 11 As shown, a placement groove 3131 is provided on the side of the charging head 31 facing away from the charging base 32, and a positioning groove 3132 and a positioning protrusion 3133 are provided on the bottom wall of the placement groove 3131. A positioning hole 3135 corresponding to the positioning protrusion 3133 is provided on the sensing circuit board 3134. The sensing circuit board 3134 is placed in the placement groove 3131, and the outer peripheral side wall of the sensing circuit board 3134 is fitted with the groove wall of the positioning groove 3132 and the positioning protrusion 3133 extends into the positioning hole 3135, thereby positioning the sensing circuit board 3134, so as to facilitate the fastening connection between the first fastener 324 and the sensing circuit board 3134.
[0072] like Figure 12 As shown, in order to prevent the primary induction coil 312 and the induction circuit board 3134 from being damaged due to overheating, a heat conducting plate 315 is provided between the induction circuit board 3134 and the primary induction coil 312. The outer shell of the charging head 31 is made of a heat conducting material. The outer peripheral side wall of the heat conducting plate 315 contacts the inner wall of the outer shell for heat conduction, thereby preventing the primary induction coil 312 and the induction circuit board 3134 from being damaged due to overheating.
[0073] In addition to the above-mentioned preferred embodiments, the present invention has other implementation methods. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
