DETAILED DESCRIPTION

[0035] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0036] The embodiments described in some embodiments of the present disclosure below do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0037] The embodiment of the present disclosure provides a wireless charging device, which can be used to wirelessly charge electronic devices. It is a magnetic wireless charging device, that is, the electronic device can be magnetically attracted to it for charging. This magnetic charging method requires sufficient magnetic attraction strength, especially in the application of vehicle-mounted wireless charging devices. To this end, the present disclosure provides a wireless charging device with a small size and good magnetic attraction effect.

[0038] Reference Figures 1 to 3 , Figure 5The wireless charging device includes a shell 10 and a mainboard module 31, a magnetic component 20 and a charging unit 30 arranged in the shell 10. The shell 10 encloses a accommodating cavity, and the mainboard module 31, the magnetic component 20 and the charging unit 30 can be arranged in the accommodating cavity. The mainboard module 31 can be installed on the shell 10, and the magnetic component 20 and the charging unit 30 can both be arranged on the magnetic component 20 and be located on the same side of the magnetic component 20. The electronic device can be placed on the shell 10, and the magnetic component 20 can magnetically attract the electronic device placed on the shell 10, so that the electronic device remains thereon. The charging unit 30 can charge the electronic device. The mainboard module 31 can be arranged in the axial direction of the magnetic component 20 ( Figure 5 The outer shell 10 includes a circumferential wall 11 surrounding the outer shell 10, and a radially inwardly extending fastening structure 111 and a snap-on structure 112 are provided on the circumferential wall 11 for fixing the mainboard module 31, that is, the mainboard module 31 is firmly installed on the outer shell 10 by the fastening structure 111 and the snap-on structure 112. It should be noted that the fastening structure 111 here refers to the mainboard module 31 that can be axially penetrated so as to be axially fastened by the fastening structure 111. This structure requires the intervention of external fastening operations (such as operator fastening operations), so when fastening the mainboard module 31, the space of the magnetic suction component 20 will be occupied. The snap-on structure 112 refers to the structure that can stop the mainboard module 31 (including but not limited to pressing on one side of the mainboard module 31). This structure does not require the intervention of external actions, and can be snap-on, thereby eliminating the space required for operation.

[0039] Through the above technical solution, the fixing of the mainboard module 31 in the wireless charging device is achieved through the fastening structure 111 and the clamping structure 112, wherein the fastening structure 111 with a better fastening effect is combined with the clamping structure 112 that occupies space and does not affect the magnetic attraction part 20, the fastening structure 111 can prevent the magnetic attraction between the wireless charging device and the electronic device from causing the clamping structure 112 to be separated, and the clamping structure 112 can avoid affecting the size of the magnetic attraction part 20. The wireless charging device in the embodiment of the present disclosure not only ensures a stable magnetic attraction effect on the electronic device, but also avoids making the overall outer contour of the wireless charging device too large and inconvenient to arrange in order to install the mainboard module 31, and can effectively solve the contradiction between the miniaturization of the wireless charging device and sufficient magnetic attraction strength.

[0040] In the present disclosure, refer to Figure 2 The fastening structure 111 and the clamping structure 112 can be located on two radially opposite sides of the circumferential wall 11, so that the mainboard module 31 can be subjected to force on two symmetrical sides, thereby ensuring its installation effect and preventing it from falling off.

[0041] The magnetic attraction member 20 may be configured in a ring shape to provide uniform magnetic attraction force in the circumferential direction.

[0042] The magnetic member 20 may be provided with a notch 21 for avoiding the fastening structure 111. That is, in order to realize the setting of the fastening structure 111 to fix the mainboard module 31, the fastening structure 111 will extend to the position of the magnetic member 20 and occupy the annular area of ​​the magnetic member 20. Therefore, a notch 21 is provided in the annular area for avoiding, so as to provide sufficient layout space and operation space during fastening. The notch 21 may be Figure 2 The disconnection form shown can also be Figure 3 Subtractive form shown.

[0043] The snap-fit ​​structure 112 can be located in the radial spacing area between the circumferential wall 11 and the magnetic member 20, which will not occupy the area of ​​the magnetic member 20 and will not affect the magnetic attraction effect. When there is the above-mentioned notch 21, the presence of the notch 21 will cause the magnetic attraction of the magnetic member 20 to weaken, affecting the magnetic attraction effect on the electronic device. In the embodiment of the present disclosure, the mainboard module 31 is further installed in combination with the snap-fit ​​structure 112 that does not occupy the space of the magnetic member 20, which not only ensures the installation effect, but also reduces the impact on the magnetic attraction performance.

[0044] According to an embodiment of the present disclosure, a fastening structure 111 that occupies a larger space can be provided at one location, and a snap-on structure 112 can be provided at one or more locations. The fastening structure 111 can prevent the mainboard module 31 from being separated from the snap-on structure 112 under the magnetic attraction of the electronic device, and the snap-on structure 112 can further enhance the fastening effect of the fastening structure 111. The combination of the two can ensure installation stability.

[0045] Combination Figures 5 to 7 , the mainboard module 31 includes a mainboard body 311 and a rigid support member 312 connected between the mainboard body 311 and the magnetic attraction member 20. The charging unit 30 may include a coil 32, and the mainboard body 311 may be used to be electrically connected to the coil 32, so as to charge the electronic device through the coil 32. Among them, the fastening structure 111 and the clamping structure 112 may respectively fix the mainboard module 31 to the housing 10 through the rigid support member 312. The rigid support member 312 is more rigid than the mainboard body 311, so fixing it through the rigid support member 312 can ensure the fixing stability of the mainboard body 311 and avoid damage to the mainboard body 311.

[0046] Reference Figure 1The mainboard module 31 may also include a shielding member 313. The shielding member 313 and the rigid support member 312 may sandwich the mainboard body 311 between the two, which may not only shield the mainboard body 311 from the magnetic field, but also protect the mainboard body 311 and provide sufficient rigidity for the installation of the mainboard body 311 to ensure the installation effect. A boss may be formed inside the housing 10, and the shielding member 313 may be placed on the boss. The fastening structure 111 and the clamping structure 112 may abut the mainboard module 31 against the boss, thereby achieving connection and installation with the housing 10.

[0047] To ensure the integrity of the components in the housing 10, the magnetic member 20 and the charging unit 30 can be connected together, for example, by bonding. When the rigid support member 312 and the main board body 311 are provided, the rigid support member 312 can be bonded to the main board body 311 and the magnetic member 20 respectively, so that the components are tightly connected, so that the components in the housing 10 can be fixed by the fastening structure 111 and the clamping structure 112.

[0048] According to an embodiment of the present disclosure, the fastening structure 111 may be formed with a mounting hole for the fastener 1111 to pass through, and the fastener 1111 can be locked to the housing 10 on the side of the mainboard module 31 facing away from the magnetic attraction member 20 after passing through the fastening structure 111 and the mainboard module 31 in sequence. The fastening structure 111 can be used to fix multiple components in the axial direction, thereby overcoming the magnetic attraction between the electronic device and the magnetic attraction member 20.

[0049] According to one embodiment of the present disclosure, referring to Figure 4 , Figure 7 and Fig. 9 The clamping structure 112 may include a first clamping protrusion 1121 extending radially inward from the circumferential wall 11, and the first clamping protrusion 1121 is used to press the mainboard module 31 to the housing 10 on the side of the mainboard module 31 facing the magnetic attraction member 20. Figure 7 In the direction shown in the figure, the first protrusion 1121 is used to press the mainboard module 31 downward onto the housing 10. Figure 6 In the embodiment, the fastener 1111 fixes the mainboard module 31 downward to the housing 10 on one side, and combines Figure 7 The first protrusion 1121 in the housing presses the mainboard module 31 downward on the other side, so that the mainboard module 31 is fixed to the housing 10 under the force of two places, preventing the mainboard module 31 from being separated from the housing 10. The number of the first protrusion 1121 can be one or more, and the present disclosure does not limit this.

[0050] Reference Figure 4 and Fig. 9The clamping structure 112 may include a second clamping protrusion 1122 extending radially inward from the circumferential wall 11, and a clamping groove 3121 is formed on the mainboard module 31 for plugging and matching with the second clamping protrusion 1122. Through the cooperation of the clamping groove 3121 and the second clamping protrusion 1122, the circumferential positioning of the mainboard module 31 can be achieved to prevent the mainboard module 31 from rotating circumferentially. Through the above-mentioned axial positioning and the circumferential positioning of the second clamping protrusion 1122, the mainboard module 31 can be fixed in all directions, thereby ensuring the stability of the internal structure of the wireless charging module, so as to obtain a wireless charging module with higher reliability, so that it can be applied to unstable scenes, such as bumpy vehicles. In one embodiment, the second clamping protrusion 1122 can be set on both sides of the first clamping protrusion 1121 to ensure the circumferential positioning effect of the axially positioned first clamping protrusion 1121, so as to avoid the rotation and shaking of the mainboard module 31, to ensure the axial positioning effect of the first clamping protrusion 1121, and avoid the failure of the clamping.

[0051] In the present disclosure, refer to Figure 2 and Figure 8 The mainboard module 31 may be provided with a light emitting element 40, such as an LED lamp bead. A light emitting area 51 may be provided on one side of the housing 10 for placing the electronic device (see Figure 6 and Figure 7 ), a light guide channel can be formed between the light emitting element 40 and the light emitting area 51. When the light emitting element 40 emits light, the light will be emitted to the light emitting area 51 along the light guide channel, so that the light emitting area 51 emits light. By setting the light emitting area 51 on the side where the electronic device is placed, the technological sense of the wireless charging device can be enhanced. In addition, the light emitting element 40 can be electrically connected to the mainboard module 31, and it can be arranged that when charging the electronic device, the mainboard module 31 controls the light emitting element 40 to emit light, thereby distinguishing the charging state and the idle state of the wireless charging device.

[0052] In the disclosed embodiment, the mainboard module 31 can be used to control the light emitting element 40 to achieve a breathing light effect, so as to further enhance the sense of technology.

[0053] Reference Figure 1 , Figures 5 to 8 , the wireless charging device may include a light guide shell 50, the light guide shell 50 includes a flat plate 52 and a cover body 53 formed on the flat plate 52, the cover body 53 is used to cover the light-emitting element 40, the light-guiding channel is configured from the cover body 53 to the flat plate 52, and the light-emitting area 51 is configured on the flat plate 52. In short, when the light-emitting element 40 emits light, the light will be emitted into the cover body 53 covered on the light-emitting element 40, and further diverge from the cover body 53 to the flat plate 52, and then emitted from the light-emitting area 51. The cover body 53 may be a cylindrical cover, and a plurality of light-emitting elements 40 may be provided, and may be circumferentially arranged in the space covered by the cover body 53. Among them, when the above-mentioned rigid support member 312 and other structures are included, such as Figure 1As shown, a hole can be dug in the middle position so that there is no light shielding object between the light emitting element 40 and the cover body 53 to block the light source. In other embodiments, the light emitting channel can also be formed by the gap between the housing 10 and the light emitting element 40.

[0054] Reference Figure 1 As shown, the housing 10 may include a cover plate 12 for covering the middle area of ​​the flat plate 52, and the light-emitting area 51 is configured to circumferentially surround the cover plate 12. The circumferential arrangement of the light-emitting area 51 can facilitate observation. The light-guiding shell 50 can be made of a semi-transparent polycarbonate material, and the cover plate 12 can be made of a black rubber material, which can ensure the shading effect and provide a certain friction for the electronic device.

[0055] The wireless charging device in the embodiment of the present disclosure can be applied to various scenarios, and when it is applied to a vehicle with bumps, it can better demonstrate its excellent effect of stabilizing electronic devices. In one embodiment, when the wireless charging device is applied to a vehicle, the wireless charging device may include a connecting arm 60, wherein the connecting arm 60 is connected to the vehicle. Fig.10 The connecting arm 60 is used to electrically connect the charging unit 30 and the central control 70 of the vehicle. For example, the connecting arm 60 can be electrically connected to the copper sheet of the central control 70 through a pin point, and then electrically connected to the charging unit 30 through a harness in the connecting arm 60. Among them, the connecting arm 60 can be mechanically connected to the housing 10, and can be mechanically connected to the central control 70 through a fastener. By setting the connecting arm 60, charging can be achieved through the central control 70, and a support effect can be provided. Compared with the charging cable connection method, the situation where the charging cable head is disconnected during the vehicle driving and causes charging failure is avoided.

[0056] The connecting arm 60 is used to be arranged at the rear side of the central control 70 so as not to affect the use of the front side of the central control 70. The front side here refers to the side facing the user, and the rear side refers to the side away from the user. The connecting arm 60 may include a first section 61 and a second section 62 connected to each other. The first section 61 is used to be electrically plugged into the rear side of the central control 70. The second section 62 is configured to be bent from the first section 61 to extend toward the periphery of the central control 70. Through the bending setting of the second section 62, the wireless charging device can be led out from the rear side of the central control 70, which is convenient for the user to perform charging operations. In addition, the bending setting can increase the length of the connecting arm 60 to ensure that the components inside it can have sufficient layout space.

[0057] According to a second aspect of an embodiment of the present disclosure, a vehicle central control system is provided, including a central control 70 and the above-mentioned wireless charging device, and having all the beneficial effects of the above-mentioned wireless charging device, which will not be repeated here.

[0058] According to a third aspect of an embodiment of the present disclosure, a vehicle is provided, comprising the above-mentioned wireless charging device, which can be connected to a central control, and the connection method is not limited to the above-mentioned connecting arm form, and can also be a wire harness connection, etc. The wireless charging device can also be connected to other positions of the vehicle, which is not limited by the present disclosure.

[0059] The vehicle may be a hybrid vehicle, a non-hybrid vehicle, an electric vehicle, a fuel cell vehicle, or another type of vehicle. The vehicle may be an autonomous vehicle, a semi-autonomous vehicle, or a non-autonomous vehicle.

For example, if the device in the drawings is turned over, the element described as being "above" or "upper" relative to another element will be "below" or "lower" relative to the other element. Therefore, depending on the spatial orientation of the device, the term "above" includes both upper and lower orientations. The device may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatially relative terms used herein should be interpreted accordingly.
