DETAILED DESCRIPTION

[0037] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0038] Figure 1 A schematic diagram of the three-dimensional structure of a first embodiment of a wireless charging device according to the present invention is shown; Figure 2 FIG2 shows a schematic diagram of the three-dimensional structure of the second embodiment of the wireless charging device of the present invention. Figure 1As shown, the wireless charging device includes a housing mechanism 1 and a wireless charging mechanism 2. The housing mechanism 1 includes a connector 11, a first clamping assembly 12, and a second clamping assembly 13. The connector 11 is used to connect to a certain area inside the vehicle. The first and second clamping assemblies 12, 13 are arranged parallel to and connected above the connector 11. The first and / or second clamping assemblies 12, 13 are used to limit the position of the mobile terminal. The wireless charging mechanism 2 is located in the first and / or second clamping assemblies 12, 13 and is electrically connected to the vehicle system.

[0039] The mobile terminal can be implemented as any device that supports wireless charging, such as a smartphone, iPad, laptop, power bank, smartwatch, etc. The mobile terminal is connected to the vehicle system via Bluetooth, the in-vehicle local area network, or other short-range communication methods. In the following, this application uses a mobile phone as an example to illustrate the wireless charging device solution, but the solution is still applicable to other terminal devices that support in-vehicle wireless charging.

[0040] It should be noted that the first clamping assembly 12 and the second clamping assembly 13 can adopt a structure of any shape, as long as they can play the role of clamping the mobile phone. Therefore, in this application, the first clamping assembly 12 and the second clamping assembly 13 can adopt the same structure or different structures. In addition, the first clamping assembly 12 and the second clamping assembly 13 can not only limit the mobile phone individually, but also cooperate with each other to limit the mobile phone. In order to make the mobile phone more difficult to move during the charging process, the mobile phone can be placed between the first clamping assembly 12 and the second clamping assembly 13. At this time, the connecting member 11 supports the mobile phone, and the first clamping assembly 12 and the second clamping assembly 13 together stabilize the mobile phone, and the wireless charging mechanism 2 can charge the mobile phone. Since the specific wireless charging process is controlled by the internal chip of the wireless charging assembly, it belongs to the existing technology, and this application will not elaborate on how to achieve charging.

[0041] In some possible implementations, such as Figure 1 As shown, the wireless charging mechanism 2 is a charging coil module, which is located in the second clamping assembly 13 and is electrically connected to the vehicle system. Figure 2 The wireless charging mechanism 2 includes a first coil module 21 and a second coil module 22. The first coil module 21 and the second coil module 22 are both electrically connected to the vehicle system. The first coil module 21 is located in the first clamping component 12 and is electrically connected to the vehicle system. The second coil module 22 is located in the second clamping component 13 and is electrically connected to the vehicle system. The axis of the first coil module 21 and the axis of the second coil module 22 are coaxial with the axis of the wireless charging coil module of the mobile phone.

[0042] When the wireless charging mechanism 2 is located only in the first clamping assembly 12 or the second clamping assembly 13, to ensure a good charging effect, the user needs to pay attention to which side of the phone the charging coil is located when placing the phone, and place that side close to the wireless charging mechanism 2. However, when the wireless charging mechanism 2 is located in the first clamping assembly 12 and the second clamping assembly 13, and the corresponding charging program is configured, since the wireless charging mechanisms 2 in the first clamping assembly 12 and the second clamping assembly 13 can operate independently, the user no longer needs to consider the placement of the phone when placing the phone, greatly facilitating the applicability of the entire wireless charging device. In addition, when the phone's wireless charging coil is located in a straight line with the first coil module 21 and the second coil module 22, the closer the distance, the greater the charging current and the higher the efficiency.

[0043] In some possible implementations, such as Figure 2 As shown, in order to further charge the mobile phone, the accommodating mechanism 1 also includes at least two baffles 14, which are connected to the first clamping assembly 12 and the second clamping assembly 13 and enclose an area for accommodating the mobile terminal together with the first clamping assembly 12 and the second clamping assembly 13.

[0044] During use of the wireless charging device in the present application, the first clamping component 12, the second clamping component 13 and the baffle plate 14 cooperate to limit the mobile phone, making it difficult for the mobile phone to move during the entire charging process, thereby helping to ensure that the mobile phone can be charged smoothly, even in bumpy road conditions, it will not affect the normal charging of the mobile phone; by arranging the wireless charging mechanism 2 in the first clamping component 12 and / or the second clamping component 13, the charging method of the entire wireless charging device is enriched, especially when the wireless charging mechanism 2 is arranged in the first clamping component 12 and the second clamping component 13, the process of users placing the mobile phone can be greatly facilitated.

[0045] Figure 3 shows an exploded view of a second embodiment of a wireless charging device of the present invention, Figure 4 FIG4 shows a cross-sectional view of a fourth embodiment of a wireless charging device according to the present invention. Figure 3 and Figure 4 As shown, in order to simplify the structure of the entire wireless charging device and reduce the design cost, the first clamping component 12 and the second clamping component 13 can be set to a symmetrical structure, that is:

[0046] The first clamping assembly 12 and the second clamping assembly 13 are both vertically connected to the connecting member 11. The first clamping assembly 12 and the second clamping assembly 13 each include a rear housing 121, a front housing 122, and an elastic assembly 123. The rear housing 121 and the front housing 122 are detachably connected, and when the rear housing 121 and the front housing 122 are covered, they form a hollow box. The front housing 122 in the first clamping assembly 12 and the second clamping assembly 13 is close to the mobile phone 6, and the wireless charging mechanism 2 is connected to the hollow box formed by the rear housing 121 and the front housing 122. The elastic assembly 123 is arranged between the rear housing 121 and the front housing 122. The elastic assembly 123 extends and contracts perpendicular to the plane of the front housing 122 and is used to drive the front housing 122 to move toward or away from the rear housing 121.

[0047] It should be noted that the elastic component 123 is any structure that can achieve the reciprocating movement of the front shell 122. For the convenience of obtaining materials, the elastic component 123 can be a spring. In some possible embodiments, such as Figure 3 The number of elastic components 123 can be four and distributed at the four corners of the first clamping component 12 and the second clamping component 13 .

[0048] like Figure 4 As shown, the rear shell 121 and the front shell 122 are provided with a first guide member 31 and a second guide member 32 that cooperate with each other. The first guide member 31 is a sleeve, which is integrally connected to the front shell 122. The second guide member 32 is a connecting tube, which is integrally connected to the rear shell 121. The inner diameter of the sleeve is equal to the outer diameter of the connecting tube, and the sleeve is sleeved on the outer wall of the connecting tube and is horizontally slidably connected to the connecting tube. One end of the elastic component 123 is located in the connecting tube and is bonded to the rear shell 121. The other end of the elastic component 123 is located in the sleeve and is bonded and fixed to the front shell 122.

[0049] In some possible embodiments, Figure 3 As shown, to further prevent the mobile phone 6 from moving, the enclosure plates 14 are provided as two parallel pieces, both bolted to the rear housing 121. A clamping member is provided on the enclosure plates 14, which is a second elastic member 5. The second elastic member 5 is in an expanded state and retracts toward the enclosure plates 14. The second elastic member 5 abuts against the side wall of the mobile phone 6 and serves to limit the mobile phone's position. For ease of material acquisition, the second elastic member 5 is a spring sheet. Two spring sheets are provided, one on each side of the mobile phone 6. The bent ends of the spring sheet are bolted to one of the enclosure plates 14.

[0050] During use, the wireless charging device of this application comprises an elastic component 123, a first guide member 31, and a second guide member 32. The elastic component 123 is capable of adjusting the distance between the first clamping component 12 and the second clamping component 13. When a mobile phone 6 is placed, the mobile phone 6 presses the front housing 122 toward the rear housing 121, compressing the elastic component 123 and allowing the connecting tube to enter the sleeve. After the mobile phone 6 is placed, the front housing 122 returns to its original position under the elastic force of the elastic component 123, allowing the front housing 122 to fit snugly with the mobile phone 6. This not only helps shorten the distance between the wireless charging mechanism 2 and the charging coil of the mobile phone 6, improving the charging efficiency of the wireless charging device for the mobile phone 6, but also further reduces the possibility of movement of the mobile phone 6 during charging, facilitating smooth charging of the mobile phone 6. The second elastic member 5 further secures the mobile phone 6 in place, preventing it from shaking and promoting a more effective charging effect of the wireless charging device for the mobile phone 6. In addition, because the elastic component 123 expands and contracts linearly under the guidance of the first guide member 31 and the second guide member 32, the front housing 122 can only move horizontally, which helps to prevent the front housing 122 from moving with the mobile phone 6. Moreover, by providing the limiter 4, the limiter 4 can limit the front housing 122, helping to ensure that the elastic component 123 can function for a long time.

[0051] In some optional ways, combined with Figure 3 and Figure 4 As shown, the rear housing 121 is configured as a frame without side panels, with the hollow chamber of the rear housing 121 facing the front housing 122. The front housing 122 can be configured as a flat plate. A stopper 4 is provided at the connection between the front and rear housings 122, 121. The stopper 4 includes flexible stoppers 41. The stoppers 41 can be provided in four pieces, two of which are fixedly connected to the top wall of the front housing 122, and the other two are fixedly connected to the bottom wall of the front housing 122. Sliding slots 1211 are defined in both the top and bottom walls of the rear housing 121. The length of the sliding slots 1211 is aligned with the direction of expansion and contraction of the elastic assembly 123. The stoppers 41 are located in the sliding slots 1211 and slide along them.

[0052] It should be noted that in order to prevent the mobile phone from being scratched, the side wall of the front shell 121 close to the mobile phone can be made of flexible materials such as silicone. At this time, even if the front shell 121 fits the surface of the mobile phone, it is not easy to damage the outer surface of the mobile phone, especially the glass surface of the mobile phone can be well protected.

[0053] In some optional ways, such as Figure 4As shown, the limiting member 4 further includes a flexible connecting strip 42 , one end of which is integrally connected to the outer wall of the front shell 122 , and the top wall of the other end is integrally connected to the limiting block 41 . When installing the front shell 122, press the limit block 41 and push the front shell 122 in the direction of the rear shell 121 at the same time. At this time, the limit block 41 and the connecting strip 42 can be pressed into the rear shell 121. Continue to push the front shell 122, and the limit block 41 can enter the sliding groove 1211. Without applying force to the limit block 41, the limit block 41 is not easy to move out of the sliding groove 1211. Therefore, the front shell 122 is not easy to separate from the rear shell 121, and the elastic component 123 can play a lasting role. When the mobile phone 6 is placed between the two front shells 122, the limit block 41 slides in the sliding groove 1211 and does not affect the movement and reset of the front shell 122. When the front shell 122 needs to be disassembled, it is only necessary to press the limit block 41 and move the front shell 122 in the direction away from the rear shell 121. It is simple and convenient.

[0054] During use of the wireless charging device in the present application, by providing the limiter 4, the front shell 122 and the rear shell 121 can be easily installed and disassembled, and the front shell 122 and the rear shell 121 are not easily separated during use of the entire wireless charging device, thereby enabling the first clamping component 12 and the second clamping component 13 to function for a long time under the action of the elastic component 123.

[0055] In some optional ways, such as Figure 4 As shown, since the heat generated by the mobile phone 6 during the charging process and the heat generated by the coil in the wireless charging plate are not easy to dissipate, the service life of the mobile phone 6 motherboard and the charging coil will be shortened. Therefore, the connecting member 11 can be set as a flat plate, and the connecting member 11 is connected to the auxiliary instrument panel of the car by bolts. The front shell 122 and the rear shell 121 are evenly provided with multiple heat dissipation holes 1222, and one of the rear shells 121 is facing the air duct 7 of the cold air system of the inner panel of the auxiliary instrument panel.

[0056] In some embodiments, combined Figure 3 and Figure 4 As shown, the top of the connector 11 can be connected to a protrusion 111 that abuts against the bottom wall of the mobile phone 6. The top of the protrusion 111 is provided with a groove, and the two ends of the groove are open. There can be multiple protrusions 111, as long as they can play the role of limiting the position of the mobile phone 6.

[0057] During use of the wireless charging device in the present application, by placing the air duct 7 directly against the rear shell 121, when the mobile phone 6 is charging, the internal chip of the wireless charging assembly can detect whether there is a risk of overheating during the charging process. If there is a risk of overheating, the cold air system is controlled to open, and the entire wireless charging device is cooled through the air duct 7; at this time, in addition to limiting the mobile phone 6 from the bottom, the protrusion 111 also increases the blowing area to a certain extent, thereby promoting rapid heat dissipation of the mobile phone 6 during the charging process; in addition, by connecting the wireless charging device to the auxiliary instrument panel of the car, the cold air of the air-conditioning system flows on the inner plate of the auxiliary instrument panel. Even if the mobile phone 6 is charging in winter, the cold air is not easy to blow on the user's activity or operation area, thereby improving the user's comfort.

[0058] Figure 5 The flowchart of the first embodiment of the wireless charging device charging method of the present invention is shown, which is applicable to the case where the wireless charging mechanism 2 is located in the first clamping component 12 or the second clamping component 13. For the convenience of description, the wireless charging mechanism 2 is located in the first clamping component 12 as an example. In this case, the wireless charging mechanism 2 includes a charging coil module, which is located in the first clamping component 12 and is electrically connected to the vehicle system. Figure 5 As shown, the charging method includes the following steps:

[0059] Step 110: Place the mobile phone 6 between the first clamping assembly 12 and the second clamping assembly 13, with the wireless charging coil of the mobile phone 6 close to the first clamping assembly 12;

[0060] The first clamping assembly 12 and the second clamping assembly 13 can clamp the mobile phone 6 .

[0061] Step 120: The charging coil module is turned on to charge the mobile phone 6.

[0062] Figure 6 The flowchart of the second embodiment of the wireless charging device charging method of the present invention is shown, which is applicable to the case where the wireless charging mechanism 2 is located in the first clamping component 12 and the second clamping component 13. At this time, the wireless charging mechanism 2 includes a first coil module 21 and a second coil module 22. The first coil module 21 is located in the first clamping component 12 and is electrically connected to the vehicle system. The second coil module 22 is located in the second clamping component 13 and is electrically connected to the vehicle system. Figure 6 As shown, the charging method includes the following steps:

[0063] Step 110: Place the mobile phone 6 between the first clamping assembly 12 and the second clamping assembly 13;

[0064] The first clamping assembly 12 and the second clamping assembly 13 can clamp the mobile phone 6 .

[0065] Step 120 : Determine whether the wireless charging coil of the mobile phone 6 is close to the first coil module 21 . If so, the first coil module 21 is turned on to charge the mobile phone 6 . If not, the second coil module 22 is turned on to charge the mobile phone 6 .

[0066] The charging current of the first coil module 21 is set to a1, and the charging current of the second coil module 22 is set to a2. The wireless charging assembly contains a chip that records the charging current, allowing comparison of the charging currents. If the wireless charging coil of the mobile phone 6 is close to the first coil module 21, the charging current is a1>a2, the second coil module 22 is turned off, and the first coil module 21 is turned on and charges the mobile phone 6, at this time the charging current is a1. If the wireless charging coil of the mobile phone 6 is close to the second coil module 22, the charging current is a1<a2, the first coil module 21 is turned off, and the second coil module 22 is turned on and charges the mobile phone 6, at this time the charging current is a2.

[0067] It should be noted that, since the wireless charging coils in the mobile terminal are all located on a side of the mobile terminal away from the screen, the situation where a1=a2 does not exist.

[0068] By applying the above technical solution of the present invention, by setting the first coil module 21 and the second coil module 22, and being able to switch between the two modes of charging the mobile phone 6 with the first coil module 21 or charging the mobile phone 6 with the second coil module 22 based on the distance between the wireless charging coil of the mobile phone 6 and the first coil module 21 and the second coil module 22, it can be ensured that the mobile phone 6 is not burned by the large current, and it can also ensure that the user can quickly charge the mobile phone 6 no matter where the mobile phone 6 is placed.

[0069] The present invention also provides a car, including the aforementioned wireless charging device, which is connected to a suitable area within the car via a connector 11. Installing the aforementioned wireless charging device in a car facilitates wireless charging of a user's mobile device while driving, and the charging effect of the mobile device is not affected by the road conditions.
