[0002] With the rapid development and popularization of wireless charging for mobile phones, wireless charging for mobile phones in cars has become an urgent need for car owners. Wireless charging for mobile phones in cars usually uses the principle of electromagnetic induction. A transmitting coil is arranged under the wireless charger panel. The changing current passing through the transmitting coil will generate a changing magnetic field. The receiving coil of the mobile phone will generate a coupled electromotive force, thereby generating current in the receiving coil and transmitting energy. The coil is usually wound with copper wire. The copper wire itself has resistance and will generate heat when current passes through it. Generally speaking, the greater the wireless charging power, the greater the heat generated by the coil.

[0047] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0048] It should be noted that the directions or positional relationships indicated by "front", "rear", "inside", "outside", "up" and "down" in this embodiment are based on the direction of the vehicle itself, where the head of the vehicle represents "front", the rear of the vehicle represents "rear", the top of the vehicle represents "up", and the bottom of the vehicle represents "down", the "inside" side refers to the side facing inside the cab, and the "outside" side refers to the side facing outside the cab.

[0049] In addition, in the embodiments of the present utility model, the front-back direction of the vehicle body is defined as the front-back direction in the forward direction during the driving of the vehicle, the left-right direction of the vehicle body is defined as the left-right direction in the forward direction during the driving of the vehicle, and the up-down direction of the vehicle body is defined as the up-down direction in the forward direction during the driving of the vehicle.

[0050] Please refer to Figures 1 to 6 together, and now a vehicle-mounted wireless charging and heat dissipation structure provided by the present utility model will be described. The vehicle-mounted wireless charging and heat dissipation structure includes a mounting base 1, a charging structure 2, a heat dissipation air duct 3, and a rotating blocking structure 4. A relief opening 11 is formed in the mounting base 1; the charging structure 2 is located inside the mounting base 1, and the upper end thereof surrounds the relief opening 11; a heat dissipation hole 231 is provided on the upper surface of the charging structure 2; the heat dissipation air duct 3 is located inside the mounting base 1, the lower end extends into the interior of the air-conditioning air duct 7, and the upper end is connected to the charging structure 2 and communicates with the heat dissipation hole 231; air inlet holes and air outlet holes are provided on the side wall of the lower end of the heat dissipation air duct 3, and the aperture of the air inlet holes is smaller than that of the air outlet holes; the rotating blocking structure 4 is rotatably provided inside the lower end of the heat dissipation air duct 3.

[0051] Among them, when the air-conditioning air duct 7 outputs cold air, the rotating blocking structure 4 blocks the air outlet holes, and the heat dissipation air duct 3 communicates with the air-conditioning air duct 7 through the air inlet holes; when the air-conditioning air duct 7 outputs hot air, the air inlet holes and the air outlet holes communicate with the air-conditioning air duct 7.

[0052] The mounting base 1 can be a sub-instrument panel or an interior trim panel of the vehicle. Both the charging structure 2 and the heat dissipation air duct 3 are located inside the mounting base 1 and are blocked by the mounting base 1, being in a non-exposed state. The air-conditioning air duct 7 can extend into the mounting base 1 or be located outside the mounting base 1, and the heat dissipation air duct 3 is extended to enable the heat dissipation air duct 3 to communicate with the air-conditioning air duct 7. Preferably, in order to facilitate the use of the vehicle-mounted wireless charging and heat dissipation structure by vehicle occupants and optimize the structures of the air-conditioning air duct 7 and the heat dissipation air duct 3, the mounting base 1 is a sub-instrument panel.

[0053] The charging structure 2 adopts the principle of electromagnetic induction. The charging structure 2 has a transmitting coil. When current flows through the transmitting coil, the transmitting coil converts electrical energy into magnetic energy to generate an alternating magnetic field. When an electronic device approaches the charging structure 2, it is cut by the alternating magnetic field generated by the transmitting coil, and an alternating current is generated in the receiving coil of the electronic device. When the alternating current is transmitted to the electronic device and then rectified by a capacitor, the alternating current is converted into direct current to charge the electronic device.

[0054] In the prior art, the charging structure 2 itself has a heat dissipation structure, or the charging structure 2 itself can withstand a relatively high temperature, and passive heat dissipation can be used. However, electronic devices such as mobile phones are provided with an over-temperature protection strategy. When the temperature exceeds the limit value, the charging power will be actively reduced or even the charging will be stopped, resulting in the inability to achieve fast charging.

[0055] To solve the above problems, the embodiment of the present application adds a heat dissipation air duct 3, and heat dissipation holes 231 are provided on the upper surface of the charging structure 2. The heat dissipation air duct 3 is communicated with the heat dissipation holes 231 on the upper surface of the charging structure 2 and the air conditioning air duct 7. When charging, the electronic device is placed on the upper surface of the charging structure 2.

[0056] The lower end of the heat dissipation air duct 3 extends into the air conditioning air duct 7, and the extending part at the lower end is provided with an air inlet hole and an air outlet hole. The rotating blocking structure 4 has two working states, corresponding to the air conditioning delivering cold air and the air conditioning outputting hot air respectively.

[0057] Specifically, when the air conditioning outputs cold air, the rotating blocking structure 4 blocks the air outlet hole, and the air inlet hole communicates the air conditioning air duct 7 and the heat dissipation air duct 3. Therefore, part of the cold air enters the heat dissipation air duct 3 through the air inlet hole and blows towards the heat dissipation holes 231 to dissipate heat by delivering cold air to the electronic device.

[0058] When the air conditioning air duct 7 outputs hot air, the rotating blocking structure 4 rotates and no longer blocks the air outlet hole. At this time, the air inlet hole and the air outlet hole are respectively communicated with the air conditioning air duct 7, and the hot air passes through the air inlet hole and the air outlet hole in sequence. Since the air inlet hole is located upstream of the air outlet hole and the aperture of the air inlet hole is smaller than that of the air outlet hole, a negative pressure is generated in the extending part at the lower end of the heat dissipation air duct 3, and the inner cavity of the charging structure 2 begins to absorb the ambient air in the installation base 1, so that the ambient air flows between the charging structure 2 and the electronic device, thereby bringing the heat generated by the electronic device into the heat dissipation air duct 3 to dissipate heat and cool down the electronic device.

[0059] It should be noted that the rotating blocking structure 4 is an electric control structure, which is electrically connected to the vehicle-mounted control system. When the passenger starts the air conditioning to output cold air, the rotating blocking structure 4 receives the instruction at the same time and rotates to block the air outlet hole; when the passenger starts the air conditioning to output hot air, the rotating blocking structure 4 receives the instruction at the same time and rotates to no longer block the air outlet hole.

[0060] The vehicle-mounted wireless charging heat dissipation structure of the present utility model, compared with the prior art, the upper surface of the charging structure 2 is used to place electronic devices such as mobile phones and tablet computers, the heat dissipation air duct 3 is used to communicate the air conditioning air duct 7 with the heat dissipation holes 231 of the charging structure 2; the rotating blocking structure 4 is used to block the air outlet hole of the heat dissipation air duct 3 when outputting cold air, so that when the air conditioning air duct 7 outputs cold air, the cold air is used to dissipate heat to the electronic device, and when the air conditioning air duct 7 outputs hot air, the ambient air in the installation base 1 is used to dissipate heat to the electronic device, thereby achieving the purpose of ventilating and dissipating heat of the electronic device, ensuring that the electronic device is within the normal temperature range, and realizing fast charging.

[0061] In some embodiments, the above air inlet hole and air outlet hole can adopt the structures as Figure 3 and Figure 4 shown, see Figure 3 andFigure 4 , the air inlet holes include a first ventilation hole 331 and a third ventilation hole 333; the air outlet holes include a second ventilation hole 332; the first ventilation hole 331 is located upstream of the second ventilation hole 332, and the aperture of the first ventilation hole 331 is smaller than that of the second ventilation hole 332.

[0062] Among them, when the air-conditioning duct 7 outputs cold air, the rotating blocking structure 4 blocks the first ventilation hole 331 and the second ventilation hole 332, and the heat dissipation duct 3 communicates with the air-conditioning duct 7 through the third ventilation hole 333; when the air-conditioning duct 7 outputs hot air, the rotating blocking structure 4 blocks the third ventilation hole 333, and the first ventilation hole 331 and the second ventilation hole 332 communicate with the air-conditioning duct 7.

[0063] Specifically, when the air conditioner outputs cold air, the rotating blocking structure 4 blocks the first ventilation hole 331 and the second ventilation hole 332. Only the third ventilation hole 333 communicates the air-conditioning duct 7 and the heat dissipation duct 3. Therefore, part of the cold air enters the heat dissipation duct 3 through the third ventilation hole 333 and blows towards the heat dissipation holes 231 to dissipate cold air for the electronic device.

[0064] When the air-conditioning duct 7 outputs hot air, the rotating blocking structure 4 blocks the third ventilation hole 333. At this time, the first ventilation hole 331 and the second ventilation hole 332 are respectively communicated with the air-conditioning duct 7. The hot air passes through the first ventilation hole 331 and the second ventilation hole 332 in sequence. Since the first ventilation hole 331 is located upstream of the second ventilation hole 332 and the aperture of the first ventilation hole 331 is smaller than that of the second ventilation hole 332, a negative pressure is generated in the lower extending part of the heat dissipation duct 3, and the inner cavity of the charging structure 2 begins to absorb the ambient air in the mounting base 1, so that the ambient air flows between the charging structure 2 and the electronic device, thereby bringing the heat generated by the electronic device into the heat dissipation duct 3 to dissipate heat and cool down the electronic device.

[0065] In some embodiments, the above vehicle-mounted wireless charging heat dissipation structure may also adopt a structure such as Figure 2 and Figure 6 shown in, see Figure 2 and Figure 6 , the vehicle-mounted wireless charging heat dissipation structure further includes a wind collecting duct 5. The wind collecting duct 5 is arranged inside the air-conditioning duct 7 and communicates with the air-conditioning duct 7; the inner cavity diameter of the wind collecting duct 5 is smaller than that of the air-conditioning duct 7; the lower end of the heat dissipation duct 3 extends into the wind collecting duct 5.

[0066] The heat dissipation air duct 3 is communicated with the air conditioner air duct 7 through the air collecting air duct 5. The air collecting air duct 5 is arranged inside the air conditioner air duct 7, and the inner diameter of the air inlet of the air collecting air duct 5 is smaller than that of the air conditioner air duct 7. The air collecting air duct 5 functions to accumulate air volume and accelerate the air speed. Especially when the air conditioner outputs hot air, the hot air will accelerate after passing through the air collecting air duct 5 with a smaller cross-section, and will accelerate again after passing through the first ventilation hole 331. The flow rate of the hot air with a high speed will increase after passing through the second ventilation hole 332, thereby further increasing the negative pressure in this area.

[0067] In addition, the air collecting air duct 5 also functions to protect the heat dissipation air duct 3 and guide the air. The air collecting air duct 5 itself can also have a filtering function.

[0068] Please refer to Figure 6 , in some embodiments, a partition 51 is provided in the inner cavity of the air collecting air duct 5. The partition 51 divides the inner cavity of the air collecting air duct 5 into a first sub-chamber and a second sub-chamber. The first sub-chamber is communicated with the first ventilation hole 331, and the second sub-chamber is communicated with the third ventilation hole 333. The outlet end of the first ventilation hole 331 faces the first sub-chamber, and the outlet end of the third ventilation hole 333 faces the second sub-chamber.

[0069] The partition 51 functions to isolate the first ventilation hole 331 from the third ventilation hole 333, preventing cold / hot air from accumulating around the first ventilation hole 331 or the third ventilation hole 333 and impacting the heat dissipation air duct 3, causing the heat dissipation air duct 3 to vibrate and generate noise.

[0070] Specifically, when the air conditioner outputs cold air, part of the cold air passes through the first sub-chamber, and part of the cold air passes through the second sub-chamber. The cold air in the first sub-chamber re-enters the air conditioner air duct 7 through the outlet end of the air collecting air duct 5; the cold air in the second sub-chamber enters the heat dissipation air duct 3 through the third ventilation hole 333.

[0071] When the air conditioner outputs hot air, part of the hot air passes through the first sub-chamber, and part of the hot air passes through the second sub-chamber. The hot air in the second sub-chamber re-enters the air conditioner air duct 7 through the outlet end of the air collecting air duct 5; the hot air in the first sub-chamber sequentially passes through the first ventilation hole 331 and the second ventilation hole 332 to generate negative pressure.

[0072] In some embodiments, the above-mentioned first ventilation hole 331 and third ventilation hole 333 can adopt the structure as Figure 3 shown, see Figure 3 , both the first ventilation hole 331 and the second ventilation hole 333 are located on the air inlet side at the lower end of the heat dissipation air duct 3, and the second air outlet hole 332 is located on the air outlet side of the heat dissipation air duct 3.

[0073] The first ventilation hole 331 and the third ventilation hole 333 are arranged vertically at intervals and facing each other, and the first ventilation hole 331, the second ventilation hole 332, and the third ventilation hole 333 all face the flowing direction of the air flow to ensure the output volume of the cold air into the heat dissipation air duct 3 and the flow rate of the hot air through the first ventilation hole 331 and the second ventilation hole 332.

[0074] In some embodiments, the above-mentioned first ventilation hole 331 can also adopt a structure as shown in Figure 2 See Figure 2 , a guide plate 6 is provided on the outer wall of the lower end of the heat dissipation air duct 3 around the first ventilation hole 331. The air outlet end of the guide plate 6 is connected to the heat dissipation air duct 3, and the air inlet end extends obliquely outward upstream of the first ventilation hole 331.

[0075] Specifically, there are two guide plates 6, which are respectively located on both sides of the first ventilation hole 331, and the two groups of guide plates 6 are distributed in a V-shaped pattern. The two groups of guide plates 6 are both located in the air collecting air duct 5. The two groups of guide plates 6 and the air collecting air duct 5 form a diversion space, and the caliber of the air inlet of the diversion space is larger than that of the air outlet.

[0076] The guide plate 6 plays a role in guiding the hot air to gather at the first ventilation hole 331, so as to further increase the flow velocity and flow rate of the hot air, increase the negative pressure in this area, and ensure that the ambient air in the installation base 1 smoothly passes between the charging structure 2 and the electronic device.

[0077] In some embodiments, the above-mentioned heat dissipation air duct 3 can adopt a structure as shown in Figure 3 See Figure 3 , the heat dissipation air duct 3 includes a strip-shaped part 31, a flat-shaped reduced-diameter part 32 and a straight cylinder part 33 connected in sequence from top to bottom; the top of the strip-shaped part 31 is connected to the charging structure 2 and is communicated with the heat dissipation hole 231; the first ventilation hole 331, the second ventilation hole 332 and the third ventilation hole 333 are provided on the straight cylinder part 33.

[0078] The strip-shaped part 31 is of a long strip structure, and its top has a long strip hole, which is communicated with the inner cavity of the charging structure 2 and the heat dissipation hole 231. The straight cylinder part 33 is of a cylindrical structure, and the straight cylinder part 33 extends into the interior of the air-conditioning air duct 7.

[0079] The flat-shaped reduced-diameter part 32 plays a role in connecting the strip-shaped part 31 and the straight cylinder part 33 in a transitional manner. Preferably, the heat dissipation air duct 3 is an integrally formed structure, the upper end of the flat-shaped reduced-diameter part 32 is adapted to the lower end of the strip-shaped part 31, and the lower end of the flat-shaped reduced-diameter part 32 is adapted to the upper end of the straight cylinder part 33.

[0080] The inner cavity of the straight-tube portion 33 is circular, and the inner cavity of the strip portion 31 is elongated. When the air-conditioning duct 7 outputs cold air, the straight-tube portion 33 is equivalent to the air inlet end, and the strip portion 31 is equivalent to the air outlet end. The structures of the air inlet end and the air outlet end are different, and the elongated air outlet end can increase the wind speed, so that the cold air can quickly flow through the charging structure 2 and the electronic device to improve the heat dissipation efficiency.

[0081] In some embodiments, the charging structure 2 may be configured as follows: Figure 2 , Figure 4 and Figure 5 The structure shown, see Figure 2 , Figure 4 and Figure 5 The charging structure 2 includes a support sink 21, a charging module 22 and a placement plate 23. The support sink 21 is arranged at the opening 11; the charging module 22 is arranged below the support sink 21; the placement plate 23 is arranged above the support sink 21 and is provided with a heat dissipation hole 231; wherein a flow gap is formed between the placement plate 23 and the support sink 21, and the upper end of the heat dissipation duct 3 is connected to the support sink 21 and communicated with the flow gap.

[0082] The charging module 22 mainly plays the role of wireless charging, adopts the principle of electromagnetic induction, and has a transmitting coil. The placement board 23 is used to support the electronic equipment.

[0083] The support sink 21 serves to fix the charging module 22, the heat dissipation duct 3, and to block the opening 11. The support sink 21 is set to sink to form a placement cavity for setting a placement plate 23, so that the placement plate 23 also sinks, so that the electronic device can also partially sink into the placement cavity.

[0084] Preferably, the heat dissipation duct 3 is an integrated structure with the support sink 21. The cold air output by the heat dissipation duct 3 flows into the flow gap and blows toward the electronic device through the heat dissipation holes 231 to ventilate and dissipate heat for the electronic device.

[0085] In some embodiments, the support sink 21 may be Figure 4 The structure shown, see Figure 4 The support sink 21 is provided with an air hole 211. The air hole 211 serves to introduce ambient air into the flow gap.

[0086] When the air-conditioning duct 7 outputs hot air, the rotating blocking structure 4 rotates to block the third ventilation hole 333. At this time, the first ventilation hole 331 and the second ventilation hole 332 are respectively communicated with the air-conditioning duct 7. The hot air passes through the first ventilation hole 331 and the second ventilation hole 332 in sequence. Since the first ventilation hole 331 is located upstream of the second ventilation hole 332 and the aperture of the first ventilation hole 331 is smaller than that of the second ventilation hole 332, a negative pressure is generated in the lower extended part of the heat dissipation duct 3, and the air passing hole 211 starts to absorb the ambient air in the installation base 1, causing the ambient air to flow in the flow-through gap, thereby bringing the heat generated by the electronic device into the heat dissipation duct 3 to dissipate heat and cool down the electronic device.

[0087] In some embodiments, the above-mentioned rotating blocking structure 4 includes a driving motor and a rotating module. The driving motor is electrically connected to the vehicle-mounted control system; the rotating module is connected to the output shaft of the driving motor and is located inside the lower end of the heat dissipation duct 3.

[0088] Preferably, the driving motor is located in the air collecting duct 5. The driving motor is electrically connected to the vehicle-mounted control system. When the passenger starts the air conditioner to output cold air, the driving motor receives an instruction at the same time and drives the rotating module to rotate to block the first ventilation hole 331 and the second ventilation hole 332; when the passenger starts the air conditioner to output hot air, the driving motor receives an instruction at the same time and drives the rotating module to rotate to block the third ventilation hole 333.

[0089] The rotating module can be a cylindrical structure, inserted into the straight tube part 33 and fitted with the inner wall of the straight tube part 33. The rotating module has three through holes, two of which respectively correspond to the first ventilation hole 331 and the second ventilation hole 332, and the other through hole corresponds to the third ventilation hole 333. When the air-conditioning duct 7 outputs hot air, the rotating module rotates to make two of the through holes communicate with the first ventilation hole 331 and the second ventilation hole 332 respectively, and the other through hole is not communicated with the third ventilation hole 333; when the air conditioner outputs cold air, the rotating module rotates to make two of the through holes not communicate with the first ventilation hole 331 and the second ventilation hole 332, and the other through hole communicates with the third ventilation hole 333.

[0090] The rotating module can also adopt a three-template structure. The three templates respectively correspond to the first ventilation hole 331, the second ventilation hole 332 and the third ventilation hole 333. When the air-conditioning duct 7 outputs hot air, the rotating module rotates to make two of the templates move away from the first ventilation hole 331 and the second ventilation hole 332 respectively, and the other template blocks the third ventilation hole; when the air conditioner outputs cold air, the rotating module rotates to make two of the templates block the first ventilation hole 331 and the second ventilation hole 332 respectively, and the other template moves away from the third ventilation hole 333.

[0091] Based on the same inventive concept, the embodiment of the present application also provides a vehicle, including the above-mentioned vehicle-mounted wireless charging heat dissipation structure.

[0092] The vehicle provided by the present utility model, due to adopting the above-mentioned in-vehicle wireless charging and heat dissipation structure, can achieve the effect of ventilating and dissipating heat for electronic devices and realize fast charging of electronic devices regardless of the temperature environment of the vehicle.

[0093] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
