Description

Technical Field

[0001] This invention relates to the technical field of wireless charging, and more specifically, to a wireless charging device and vehicle for charging mobile phones in vehicles. Background Technology

[0002] With the development of automotive technology, users have increasingly demanded more functional features in vehicle interiors, and wireless charging technology for mobile phones and other smart devices has gradually become widespread in vehicles. Currently, in cars equipped with this function, the wireless charging device is generally integrated into the center console near the central control screen or the armrest. Wireless charging technology provides power to the device through electromagnetic induction, magnetic resonance, and other methods. Current passing through the coil of the wireless charger generates a magnetic field, and the coil in the receiving device induces the magnetic field and generates current, thereby charging the device's battery. In this electromagnetic conversion process, the energy conversion is not 100%; some electrical energy is converted into heat energy, causing the device's temperature to rise. Therefore, a certain amount of heat generated by the device during wireless charging is an inevitable result of the technology's principle. Especially under high power or prolonged charging conditions, the device will generate heat. As heat accumulates, it can affect the normal operation of the charging device, and prolonged excessive heat may also affect the device's performance and lifespan.

[0003] The demands on wireless charging functionality in vehicles are now higher, requiring not only effective ventilation and heat dissipation but also aesthetic appeal to the vehicle's interior. In high-end vehicles, interior components such as seats, headliners, sun visors, and the A, B, C, and D pillars are often covered with suede, which offers superior visual appeal, comfort, and quality details. During wireless charging, the coil on the device (usually a mobile phone) is the area with the most concentrated heat, typically the center of the back of the phone. Therefore, directly creating ventilation holes in this area within the phone holder of the wireless charging device is the most effective way to dissipate heat. Existing vehicle wireless charging phone holders typically use single-layer rubber, which is easy to process, but its appearance doesn't meet the high standards of interior design. Using a double-layer material for the phone holder offers greater versatility in surface material selection, such as suede, to suit more interior design needs. However, the hole-making process for double-layer phone holders becomes more complex, requiring additional laser processing equipment, increasing production difficulty and cost. Summary of the Invention

[0004] The purpose of this invention is to provide a wireless charging device for charging mobile phones. The mobile phone holder of the wireless charging device is set as a double-layer structure consisting of a cover and a supporting frame. Under the condition of facilitating heat dissipation, the choice of appearance material of the mobile phone holder is more diversified than that of the prior art, which can adapt to the requirements of various interior styles. At the same time, no additional laser drilling device is required during the processing, which simplifies the processing and controls the production cost.

[0005] To this end, a first aspect of the present invention provides a wireless charging device, comprising: a wireless charging module, the wireless charging module including a housing and a coil assembly disposed in the housing; a support frame disposed above the wireless charging module, the support frame being flat to support a device to be charged, and the support frame being provided with a plurality of first through holes arranged in a first array; and a cover member covering the support frame, the cover member being provided with a plurality of second through holes arranged in a second array, wherein the overlapping areas of the plurality of second through holes and the plurality of first through holes form ventilation holes.

[0006] Based on the above-described technical concept, the present invention may further include any one or more of the following optional forms.

[0007] In some alternative configurations, the plurality of second through holes are uniformly provided throughout the entire covering.

[0008] In some alternative forms, the plurality of first through holes are arranged in a first array above the center of the coil assembly.

[0009] In some alternative forms, the total area of ​​the overlapping region is not less than 280 square millimeters.

[0010] In some alternative forms, each of the second through holes is a circular hole with a diameter between 1 mm and 2 mm, and the size of each of the first through holes is larger than the size of each of the second through holes.

[0011] In some alternative forms, the support frame is provided with a plurality of protruding structures arranged around the overlapping area and protruding toward the cover to support the device to be charged.

[0012] In some alternative forms, the upper surface of the housing is provided with at least one air guide groove, one end of which communicates with the overlapping area, and the other end of which is provided with a fan to guide air from the overlapping area to the fan via the air guide groove when the fan is running.

[0013] In some alternative forms, the covering material is suede; and / or the supporting frame material is plastic.

[0014] In some alternative forms, the covering is bonded to the support frame by adhesive.

[0015] A second aspect of the invention provides a vehicle that includes a wireless charging device according to a first aspect of the invention.

[0016] Compared with the prior art, the wireless charging device according to the present invention has several beneficial technical effects, especially: the mobile phone holder of the wireless charging device is configured as a double-layer structure including a support frame and a cover, wherein the support frame is provided with a plurality of first through holes, and the cover is provided with a plurality of second through holes, and the overlapping area between the plurality of first through holes and the plurality of second through holes forms a ventilation hole, which can be used to guide airflow and dissipate heat from the mobile phone; by adopting the above-mentioned double-layer structure, the mobile phone holder can not only meet the heat dissipation requirements of the wireless charging device, but also the selection of the appearance material of the mobile phone holder can be diversified to adapt to the needs of various interior styles, and at the same time, no additional laser drilling device is required during the processing, making the processing simple and the production cost low.

It should be understood that these drawings are not only for explaining and illustrating the invention, but also, where necessary, for defining the invention. Detailed Implementation

[0026] The implementation and use of specific embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of particular ways of implementing and using the invention, and are not intended to limit the scope of the invention. The directional term "above" in this invention refers to the direction in which the wireless charging device is close to the device to be charged.

[0027] The terms "first," "second," etc., used in this invention are used to describe various elements without intending to limit the positional, temporal, or importance relationships of these elements; such terms are merely used to distinguish one element from another. It should be understood that in some embodiments, the numerical parameters used in the specification and claims are approximate values, which may be changed according to the specific characteristics required by individual embodiments.

[0028] As mentioned above, the present invention aims to provide an improvement to a wireless charging device, which improves the phone holder of the wireless charging device into a double-layer structure consisting of a cover and a supporting frame. This double-layer structure not only meets the heat dissipation requirements of wireless charging, but also allows for a variety of material choices for the cover to adapt to various interior design styles, thus improving the user experience. At the same time, no additional laser drilling device is required during the processing, which facilitates production and reduces manufacturing costs.

[0029] Reference Figure 1 The diagram illustrates the arrangement of a wireless charging device 10 according to one embodiment of the present invention. The wireless charging device 10 is installed on the passenger side dashboard of a vehicle. This arrangement facilitates wireless charging of mobile phones for front-seat users and is highly practical. The wireless charging device 10 is not limited to installation on the passenger side dashboard; it can also be installed on the rear center armrest, door panel, or seat back, etc., depending on actual needs, all achieving the same function.

[0030] Figure 2 This is an exploded view of the wireless charging device 10, as shown below. Figure 2 As shown, the wireless charging device 10 includes a wireless charging module 100, a support frame 200, and a cover 300. The support frame 200 is disposed above the wireless charging module 100 to form a phone holder for placing a device to be charged (usually a mobile phone). The cover 300 covers the support frame 200. (Refer to reference...) Figure 3 and Figure 4The support frame 200 is flat and has multiple first through holes 210 arranged in a first array. More specifically, the support frame 200 is a rigid support frame for a mobile phone holder, and its flat shape allows it to support the mobile phone. The support frame 200 has multiple first through holes 210 without affecting its support strength, and these first through holes 210 can be arranged in a circular or rectangular array. The covering 300 has multiple second through holes 310 arranged in a second array, and the multiple second through holes 310 and the multiple first through holes 210 partially overlap to form effective ventilation holes. The covering 300 is the outer layer of the mobile phone holder, and the mobile phone is placed directly on the covering 300. The multiple second through holes 310 can be arranged in a circular or rectangular array, and the array patterns of the first and second arrays can be the same or different.

[0031] It is understandable that the support frame 200 and the cover 300 are an overlay structure. Only the overlapping area between the first through hole 210 and the second through hole 310 can serve as an effective ventilation hole. The ventilation hole facilitates airflow and heat dissipation for the phone. By setting the phone holder as a double-layer structure including the support frame 200 and the cover 300, ventilation holes are formed by the overlapping areas between the multiple first through holes 210 on the support frame 200 and the multiple second through holes 310 on the cover 300. These ventilation holes can be used to guide airflow and dissipate heat for the phone. By adopting the above-mentioned double-layer structure, the phone holder can not only meet the heat dissipation requirements of the wireless charging device 10, but also diversify the choice of the phone holder's exterior materials to adapt to various interior design styles. At the same time, no additional laser drilling device is required during processing, making the processing method simple and the production cost low.

[0032] In optional embodiments, the material of the cover 300 can be selected from various covering fabrics according to the interior style of the corresponding vehicle, especially suede; and / or the material of the support frame 200 is plastic. Multiple first through holes 210 on the support frame 200 can be created during the injection molding process of the plastic part, and multiple second through holes 310 on the cover 300 can be created during the processing of the covering fabric. The perforated cover 300 is then bonded to the plastic support frame 200 by adhesive bonding or low-pressure injection molding. This processing method is simple, does not require additional laser perforation equipment, and allows for a variety of covering fabric options for the phone holder of the wireless charging device 10. Suede, in particular, offers good performance in terms of visual effect, comfort, and quality details, and can meet the interior requirements of some high-end vehicles.

[0033] According to some embodiments of the present invention, reference continues. Figure 3Multiple second through holes 310 are evenly provided on the entire covering part 300. This means that the holes are evenly opened on the entire covering part 300, so that the hole positions on the covering part 300 do not need to be considered when the covering part 300 is covering the support frame 200, which improves processing efficiency, reduces the hole positioning steps, reduces waste, and improves the utilization rate of raw materials of the covering part 300.

[0034] According to some embodiments of the present invention, reference continues. Figures 4 to 7 The wireless charging module 100 includes a coil assembly 110 and a housing 120. The coil assembly 110 is disposed inside the housing 120 and is used to induct with the coil in the mobile phone to charge the phone. The coil of the coil assembly 110 is typically configured with a symmetrical structure and has a center. The center of the coil assembly 110 corresponds to the area on the mobile phone where heat is most concentrated. Correspondingly, the multiple first through holes 210 of the support frame 200 are also arranged in a first array above the center of the coil assembly 110. Thus, when ventilating and conducting heat for the charging mobile phone, the overlapping area (ventilation holes) can correspond to the area where heat is most concentrated on the mobile phone, resulting in better heat dissipation efficiency. Furthermore, the total area of ​​the overlapping area is not less than 280 square millimeters. In particular, the center of this overlapping area should be located above the coil assembly 110, especially above the center of the coil assembly 110, to provide sufficient ventilation holes for heat dissipation and prevent overheating during charging.

[0035] In an optional embodiment, for aesthetic purposes, each second through hole 310 is set as a circular hole with a diameter of 1-2 mm, preferably around 1 mm. In practical applications, each second through hole 310 on the covering 300 is small enough that, after the covering 300 covers the support frame 200, the structure behind the covering 300 (support frame 200 and charging module 100) is essentially invisible to the user, avoiding the problem of users seeing the back structure of the interior and experiencing a poor user experience. The opening form of the support frame 200 only needs to meet the requirement of the total area of ​​the effective ventilation holes and ensure the structural strength of the support frame 200, allowing for very flexible settings. For example, the size of each first through hole 210 is larger than the size of each second through hole 310, and multiple first through holes 210 can be combined into a single structure. Figure 4 The circular array shown; or each first through hole 210 can be set as a square hole, arranged in a square array.

[0036] According to some embodiments of the present invention, reference continues. Figure 4The support frame 200 is also provided with a raised structure 220, which consists of four overlapping ribs that slightly protrude towards the cover 300. Preferably, the raised structure 220 protrudes upward by 0.8 to 1 mm. After the cover 300 covers the support frame 200, the cover 300 will also protrude accordingly at the positions corresponding to the raised structure 220. When charging, the phone can be slightly raised to support it, leaving a certain gap between the phone and the cover 300 to facilitate air circulation and further improve the heat dissipation effect.

[0037] In an optional implementation, refer to Figure 5 and Figure 6 The upper surface of the housing 120 of the wireless charging module 100 is also provided with at least one air guide slot 121, such as multiple air guide slots 121 arranged in parallel as shown. One end of each air guide slot 121 is connected to the overlapping area, and the other end is provided with a fan 130. This forms an air guiding channel between the fan 130 and the overlapping area. When the fan 130 is running, it can guide air from the overlapping area through the air guide slot 122 to the fan 130, thereby accelerating the guidance of the heat generated during mobile phone charging to the internal structure of the vehicle and improving the efficiency of air guiding and heat dissipation.

[0038] In some embodiments, the present invention also proposes a vehicle including the wireless charging device 10 described above. The number of wireless charging devices 10 can be multiple and arranged in the interior of the vehicle as needed.

[0039] The technical content and features of the present invention have been disclosed above. However, it is understood that under the creative concept of the present invention, those skilled in the art can make various flexible changes and improvements to the above-disclosed concept, but all of them fall within the protection scope of the present invention.
