DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] The embodiments of the present application provide a vehicle-mounted wireless charging ventilation pad and a wireless charger to solve the problem in the related art that the ventilation area of ​​the soft pad is easily changed and aged during use, thereby affecting heat dissipation and ventilation because the soft pad is made of all soft rubber material.

[0044] See also Figure 1-Figure 5 A vehicle-mounted wireless charging ventilation pad comprises a ventilation pad body 1, a flexible supporting protrusion 3 and a hard ventilation plate body 2; wherein the ventilation pad body 1 is provided with a ventilation opening, the hard ventilation plate body 2 is sealed in the ventilation opening, and a plurality of ventilation holes 4 are pierced thereon;

[0045] Multiple flexible support protrusions 3 are distributed in an array on the upper surface of the ventilation pad body 1, and two adjacent rows of flexible support protrusions 3 form a first flow channel; in each row of flexible support protrusions 3, a second flow channel is formed between two adjacent flexible support protrusions 3; the second flow channel is connected to the first flow channel.

[0046] The ventilation pad body 1 is made of TPE material, which has good environmental protection and odor resistance. The hard ventilation plate body 2 is made of ABS material, which has good appearance and decorativeness. The two are molded by integral injection molding. The materials of the ventilation pad body 1 and the hard ventilation plate body 2 have good odor resistance and will not produce odor during the heat dissipation process.

[0047] The upper surface of the ventilation pad body 1 and the edge of the vent are provided with an annular groove, the size of which can be 1mm×0.5mm, to distinguish between soft and hard areas, which can ensure good product consistency, and can be used as a masking spray tooling groove during later spraying; in addition, the annular groove also makes it difficult to produce burrs during the production process, thereby ensuring product quality.

[0048] Due to the above settings, when in use, the flexible support protrusion 3 on the vehicle-mounted wireless charging ventilation pad contacts the back of the mobile phone, so that there is a certain distance between the back of the mobile phone and the vent, which is convenient for the wind entering from the vent to contact the mobile phone for heat dissipation, and the flexible support protrusion 3 will not scratch the mobile phone; at the same time, the hard ventilation plate 2 will not be deformed due to external pressure, nor will it be deformed due to aging, so that it can form an effective support for the mobile phone and the ventilation pad body 1, ensuring the ventilation area and heat dissipation efficiency. Due to the combined use of soft and hard materials, while ensuring heat dissipation, it also takes into account the placement and scratching of the mobile phone.

[0049] On the other hand, since the multiple flexible support protrusions 3 are distributed in an array, two adjacent columns of flexible support protrusions 3 form a first flow channel; in each column of flexible support protrusions 3, a second flow channel is formed between two adjacent flexible support protrusions 3; the second flow channel is connected to the first flow channel, thereby enhancing the flow capacity of the airflow entering from the ventilation hole to the ventilation pad body 1, so that the airflow evenly covers the bottom surface of the mobile phone to enhance heat dissipation, adapt to the use environment of high-power wireless charging, and can greatly improve the charging efficiency and reduce the charging time compared with ordinary wireless charging modules.

[0050] In some preferred embodiments, the distribution of the plurality of flexible supporting protrusions 3 has the following specific configurations:

[0051] The first one, such as Figure 4 As shown, multiple flexible support protrusions 3 are distributed in a rectangular array, and all columns are spaced apart along the length direction of the ventilation pad body 1. The lengths of the flexible support protrusions 3 in each column in the width direction of the ventilation pad body 1 are not equal; or they can be equal; thereby forming a divergence from the hard ventilation plate body 2, and the first flow channel and the second flow channel are connected to form multiple airflow paths (criss-cross airflow).

[0052] The second type is that a plurality of flexible support protrusions 3 are distributed in a circular array, and all columns are spaced apart along the width direction of the ventilation pad body 1, and the flexible support protrusions 3 in each column are of equal size; the first flow channel and the second flow channel can also be connected to form a plurality of airflow paths (central divergence, multiple circular airflows connected), so that the airflow evenly covers the back of the mobile phone, thereby achieving the purpose of cooling the mobile phone.

[0053] In some preferred embodiments, reference Figure 3 and Figure 5 A plurality of first air outlet slots 6 are provided on one side edge of the rigid ventilation plate 2 and are spaced apart from each other; a second air outlet slot 7 is provided on one side edge of the vent and is connected to the first air outlet slot 6; the introduced air first enters from the second air outlet slot 7, then enters the first air outlet slot 6, and then enters the first flow channel and the second flow channel from the ventilation hole 4. This arrangement allows the air to flow from one side of the rigid ventilation plate 2 to the other side, and can take into account most of the ventilation holes 4.

[0054] Furthermore, a plurality of charging module contact blocks 5 are provided at the bottom of the rigid ventilation plate body 2, and the distribution direction of the plurality of charging module contact blocks 5 is parallel to the distribution direction of the plurality of first air outlet slots 6; the extension direction of the charging module contact blocks 5 is perpendicular to the distribution direction of the plurality of first air outlet slots 6 to form a plurality of flow channels (see Figure 5 The ventilation hole 4 is connected with the branch channel.

[0055] The charging module contact block 5 divides the air discharged from the first air outlet slot 6 into a plurality of branch channels in the process of passing from one side of the hard ventilation plate body 2 to the other side, thereby ensuring that each ventilation hole 4 discharges air and ensures the uniformity of the air flow. The charging module contact block 5 is also used to contact the charging module 10 and play a certain supporting role.

[0056] Furthermore, an air volume compensation distance T is provided between the end of the charging module contact block 5 close to the first air outlet slot 6 and the first air outlet slot 6, see Figure 5 As shown in the figure, the function of this setting is to prevent different sizes of mobile phones, different diversion channels can compensate each other, so that the air volume distribution is uniform and reasonable, and the air volume compensation distance T can be 4mm.

[0059] The wind generated by the air supply component 12 of the wireless charger enters from the third air inlet slot 11, the third air inlet slot 11 enters the second air outlet slot 7, then enters the first air outlet slot 6, and then enters the first flow channel and the second flow channel from the ventilation hole 4, thereby having the characteristics of large effective ventilation area and high heat dissipation efficiency. Compared with ordinary wireless charging modules, it can greatly improve the charging efficiency and reduce the charging time.

[0060] In addition, since the ventilation pad body 1 is made of TPE material and is injection molded, the material and process have good environmental protection and odor resistance. The hard ventilation plate body 2 is made of ABS material and is injection molded, so that the wireless charger has good odor resistance, is environmentally friendly, and has excellent product appearance.

[0061] In some preferred embodiments, the air supply assembly 12 includes an air flow duct and an air supply fan. One end of the air flow duct is connected to the third air inlet slot 11, and the other end is provided with an opening; the air supply fan is installed in the opening.

[0062] In some preferred embodiments, the main body shell 8 is a slot structure, and the bottom of the slot includes a horizontal surface and an inclined surface connected to each other; the mounting slot 9 is arranged on the inclined surface;

[0063] The ventilation pad body 1 includes an inclined portion and a horizontal portion corresponding to the horizontal plane and the inclined plane, and the vent is arranged on the inclined portion; through such an arrangement, the mobile phone is placed in the main body shell 8 to prevent the mobile phone from falling out therefrom.
