Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging, and more specifically, to a wireless charging rubber pad. Background Art

[0002] With the continuous improvement of the requirements of electrical equipment for power supply quality, safety, reliability, convenience, instantaneity, special occasions, special geographical environments, etc., the contact power transmission method can no longer meet the actual needs.

[0003] A wireless charger is a device that uses the principle of electromagnetic induction for charging. Its principle is similar to that of a transformer. By arranging a coil at each of the transmitting and receiving ends, the transmitting-end coil emits an electromagnetic signal to the outside under the action of electricity, and the receiving-end coil receives the electromagnetic signal and converts the electromagnetic signal into current, so as to achieve the purpose of wireless charging. Wireless charging technology is a special power supply method. It does not require a power cord, relies on the propagation of electromagnetic waves, and then converts the electromagnetic wave energy into electrical energy to finally achieve wireless charging. Compared with traditional wired charging, wireless charging does not require a wired connection to the device, and only needs to be placed at the charging place to charge, greatly improving the convenience of charging.

[0004] With the development of technology, wireless charging technology has also been popularized in automobiles. The driver only needs to place the mobile phone or a device supporting wireless charging on the charging stand to automatically charge, reducing the operations required by the driver when charging the mobile phone and avoiding the distraction of the driver's attention, greatly improving the driving safety. In order to prevent the electronic device for wireless charging from slipping off the charging place during the driving of the automobile, a wireless charging rubber pad is often provided at the charging place. During wireless charging, the device generates heat, causing the rubber pad to deform, and when the automobile is exposed to the sun outdoors, the rubber pad will also absorb a large amount of heat. Under the condition of long-term heating, the rubber pad will deform and curl, affecting the fitting of the rubber pad with the wireless charging device. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a wireless charging rubber pad, which is provided with a weakened lip, which is beneficial to reducing the deformation amount after heating and improving the fitting degree of the rubber pad.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0007] Provide a wireless charging rubber pad, the bottom of the rubber pad is provided with a connecting part for connection, and a weakened lip with a thickness smaller than that of the middle part of the rubber pad is provided on the periphery of the rubber pad.

[0008] With this setting method, the rubber pad can be inserted into the installation part on the vehicle through the connecting part, and the weakening lip with a thickness less than the center of the rubber pad is prone to deformation. The weakening lip can absorb the dimensional fluctuations of the part itself and the thermal expansion of the rubber pad after exposure to high temperatures in the sun, ensuring that the edge of the rubber pad fits tightly with the wireless charging device and preventing the rubber pad from curling.

[0009] Preferably, the weakening lip includes an eaves part and a groove part. The groove part is arranged at the bottom of the eaves part, and the groove part is used to accommodate the expansion generated by the heating of the rubber pad.

[0010] With this setting method, when the rubber pad expands due to heat, the groove part provides a space for the expanded volume, avoiding the overall size of the rubber pad from becoming larger after expansion and not matching the installation location, resulting in bulging or warping.

[0011] Preferably, the groove part is an arc structure.

[0012] With this setting method, the arc-shaped groove part has a gentle transition, avoiding the reduction of the structural strength of the rubber pad at the edge due to the sharp change in thickness.

[0013] Preferably, a plurality of first reinforcing ribs are equidistantly arranged beside the groove part.

[0014] With this setting method, although the thickness of the groove part of the rubber pad is thinner, its structural strength can still be ensured. Moreover, the setting of the first reinforcing ribs has a certain anti-tensile effect, which can further reduce the deformation amount at the edge of the rubber pad when heated and improve the service life of the rubber pad.

[0015] Preferably, the connecting part is a cylindrical structure and is made of an elastic material. A round table for limiting is arranged at the bottom of the connecting part, and the maximum diameter of the round table is larger than the diameter of the middle part of the connecting part.

[0016] With this setting method, when the rubber pad is connected to the installation part on the vehicle through the connecting part, the round table can be compressed first to pass the connecting part through the hole for insertion. When the round table passes through the hole for insertion, the larger diameter part of the round table will abut against the end of the hole, thus playing a limiting role from the other side and preventing the connecting part from slipping out of the hole, thereby ensuring that the rubber pad will not fall off from the installation location even when it deforms due to heat.

[0017] Preferably, a limiting rib is also arranged in the middle of the upper side of the rubber pad.

[0018] With this setting method, the limiting rib can limit the electronic device for wireless charging in the charging area, avoiding the electronic device from sliding out of the charging position during wireless charging; and when it is necessary to remove the rubber pad for cleaning, the limiting rib can also play a role in providing a force point.

[0019] Preferably, a plurality of convex ribs are also arranged on the upper side of the rubber pad.

[0020] With this setting method, the rubber pad can be more beautiful, and the gaps between the convex channels can also provide channels for air circulation, thereby improving the heat dissipation performance of the rubber pad and reducing the deformation caused by heat; furthermore, the convex channels can also increase the friction force on the items placed on the rubber pad, preventing the items from sliding off the rubber pad when the vehicle is moving.

[0021] Preferably, a plurality of heat dissipation bosses are further provided on the rubber pad.

[0022] With this setting method, when wirelessly charging electronic devices such as mobile phones, the heat dissipation bosses can lift the mobile phone, making the bottom back panel of the mobile phone suspended. Without affecting wireless charging, the contact area between the mobile phone and the rubber pad is reduced, thereby improving the heat dissipation efficiency of the mobile phone and the rubber pad.

[0023] Preferably, an installation box for accommodating a wireless charging module is further provided under the rubber pad, and the installation box is fixedly connected to the rubber pad.

[0024] With this setting method, the wireless charging module can be placed in the installation box at the bottom of the rubber pad, thereby reducing the distance between the wireless charging module and the electronic device above the rubber pad and improving the efficiency of wireless charging.

[0025] Preferably, a ventilation part is further provided on the rubber pad, and the ventilation part is located directly above the installation box.

[0026] With this setting method, heat exchange can be carried out through the ventilation part at the contact part between the top of the installation box and the rubber pad, thereby preventing heat generated by the wireless charging component from accumulating between the installation box and the rubber pad.

[0027] Preferably, a protruding mounting plate is provided at the bottom of the installation box, and a plurality of mounting holes are provided on the mounting plate.

[0028] With this setting method, the installation box can be fixedly connected to the peripheral parts through the mounting holes on the mounting plate.

[0029] Preferably, a plurality of second reinforcing ribs are further provided between the mounting plate and the side wall of the installation box.

[0030] With this setting method, the structural strength between the mounting plate and the installation box can be enhanced, thereby preventing stress concentration at the mounting plate and resulting in fracture.

[0031] Preferably, the rubber pad above the installation box is recessed. With this setting method, the rubber pad area above the installation box is the charging position. When an electronic device is placed in the charging position, the recessed rubber pad can play a role in limiting the electronic device, reducing the probability of the electronic device sliding out and shifting from the charging position when the vehicle is moving, and improving the stability of wireless charging.

[0032] During installation, the wireless charging rubber pad is generally installed on the upper trim panel of the vehicle's passenger instrument panel. The wireless charging rubber pad is snap-fitted to the upper trim panel of the passenger instrument panel through a connecting part, and the weakened lip on the periphery of the wireless charging rubber pad also cooperates with the upper trim panel of the passenger instrument panel. The wireless charging device can be installed in the installation box at the bottom of the rubber pad, and the installation box is connected to the passenger instrument panel through an installation plate, thus ensuring the stable installation of the overall structure of the rubber pad. When wireless charging is carried out, the electronic device can be placed on the heat dissipation bosses of the rubber pad. Gas flow channels are formed between the bosses to accelerate the heat exchange efficiency, and the electronic device is limited by the limiting ribs and is not prone to deviation, thus ensuring stable charging.

[0033] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0034] (1) The wireless charging rubber pad is provided with a weakened lip to ensure full fit between the periphery of the rubber pad and the wireless charging device, and the weakened lip can absorb the deformation generated by the rubber pad when heated, avoiding the warping of the periphery of the rubber pad and improving the assembly quality of the rubber pad and the charging device.

[0035] (2) Through the limitation of the round platform on the connecting part, it is ensured that the rubber pad is firmly connected to the device, avoiding the slippage of the rubber pad and improving the connection stability between the rubber pad and the wireless charging device.

[0036] (3) A ventilation part is provided at the rubber pad above the wireless charging module, which is conducive to the heat dissipation when the wireless charging module works; heat dissipation bosses are provided on the upper side of the rubber pad, which is beneficial to the heat dissipation of the electronic device during wireless charging, and multiple bosses are also provided on the rubber pad, which is conducive to reducing the contact area between the bottom of the electronic device and the rubber pad to increase the heat dissipation efficiency.

[0047] Through this setting method, the rubber pad 1 can be inserted into the installation part on the vehicle through the connecting part 2, and the weakened lip 3 is easy to deform, which can absorb the dimensional fluctuations of the part itself and the thermal expansion of the rubber pad 1 after exposure to high temperature in the sun, ensure that the edge of the rubber pad 1 fits tightly with the wireless charging device, and prevent the rubber pad 1 from curling.

[0048] As an implementation mode of the present utility model, the weakened lip 3 includes an eave part 31 and a groove part 32. The groove part 32 is arranged at the bottom of the eave part 31, and the groove part 32 is used to accommodate the expansion generated by the rubber pad 1 when heated.

[0049] Through this setting method, when the rubber pad 1 expands due to heat, the groove part 32 provides a space for accommodating the expanded volume, avoiding the overall size of the rubber pad 1 becoming larger after expansion and not matching the installation place, resulting in bulging or warping.

[0050] As an embodiment of the present utility model, the groove portion 32 has an arc-shaped structure.

[0051] With this setting method, the groove portion 32 with an arc-shaped structure has a smooth transition, avoiding the reduction of the structural strength of the rubber pad 1 at the edge due to the sharp change in thickness.

[0052] As an embodiment of the present utility model, a plurality of first reinforcing ribs 33 are equidistantly arranged beside the groove portion 32.

[0053] With this setting method, although the groove portion 33 of the rubber pad 1 has a thinner thickness, its structural strength can still be ensured. Moreover, the setting of the first reinforcing ribs 33 has a certain anti-tensile effect, which can further reduce the deformation amount at the edge of the rubber pad 31 when heated, and improve the service life of the rubber pad 1.

[0055] With this setting method, when the rubber pad 1 is connected to the installation part on the vehicle through the connecting portion 2, the frustum 21 can be compressed first to pass the connecting portion 2 through the hole for insertion. When the frustum 21 passes through the hole for insertion, the larger diameter part of the frustum 21 will abut against the end of the hole, thereby playing a limiting role from the other side to prevent the connecting portion 2 from slipping out of the hole, so as to ensure that the rubber pad 1 will not fall off from the installation when deformed by heat.

[0060] As an embodiment of the present utility model, a plurality of convex ribs 5 are further provided on the upper side of the rubber pad 1.

[0061] With this setting method, the rubber pad 1 can be more aesthetically pleasing, and the gaps between the convex channels 5 can also provide a passage for air circulation, thereby improving the heat dissipation performance of the rubber pad 1 and reducing the amount of deformation caused by heat; furthermore, the convex channels 5 can also increase the friction force on the items placed on the rubber pad 1, preventing the items from sliding off the rubber pad 1 when the vehicle is moving.

[0062] As an embodiment of the present utility model, a plurality of heat dissipation bosses 6 are further provided on the rubber pad 1.
