Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wireless charging, and particularly relates to a wireless charging base. BACKGROUND

[0002] In the prior art, the connection between the wireless charger of a mobile phone and the mobile phone mainly relies on magnetic attraction. A mobile phone back coil and a wireless charger coil are both provided with a ring of magnets. When the two are attracted to each other, wireless charging can be performed. However, the magnets affect the operation of the wireless charging coil, causing the charging coil to generate a large amount of heat, which in turn causes the temperature of the electronic device to be too high during charging, affecting the performance of the electronic device. SUMMARY

[0003] The application aims to provide a wireless charging base, which at least solves the problem of the electronic device being too hot due to the large amount of heat generated by the charging coil.

[0004] To solve the above technical problem, the application is implemented as follows:

[0005] In a first aspect, the application provides a wireless charging base, which comprises:

[0006] a body, the body having a cooling channel and an adsorption channel, the first end of the adsorption channel being in communication with the cooling channel;

[0007] an adsorption component, the adsorption component being connected to the body, the second end of the adsorption channel extending to the adsorption component;

[0008] a driving component, the driving component being capable of driving the medium in the cooling channel to flow and driving the medium in the adsorption channel to flow into the cooling channel, so that the adsorption component can adsorb the electronic device;

[0009] a charging coil, the charging coil being arranged in the adsorption component and capable of charging the electronic device adsorbed on the adsorption component.

[0010] In the embodiments of the present application, the wireless charging base comprises a body, an adsorption component, a driving component and a charging coil. The body has a cooling channel and an adsorption channel, the first end of the adsorption channel communicates with the cooling channel; the adsorption component is connected with the body, and the second end of the adsorption channel extends to the adsorption component to realize the mounting of the adsorption component on the body. The driving component can drive the medium in the cooling channel to flow, and can drive the medium in the adsorption channel to flow into the cooling channel. Since the driving component generates strong positive pressure airflow when working, the medium in the adsorption channel is driven to flow to one side of the cooling channel, so that negative pressure is generated in the adsorption channel, and the adsorption component can adsorb the electronic device under the action of the negative pressure, so that the electronic device and the body can be fixed together, and the medium flowing in the cooling channel can cool the electronic device and the wireless charging base. The charging coil is arranged in the adsorption component to realize the mounting and fixation of the charging coil, so that when the adsorption component and the electronic component are adsorbed together, the charging coil can charge the electronic device, thereby realizing wireless charging of the electronic device. Therefore, by using the driving component to drive the medium in the cooling channel to flow and drive the medium in the adsorption channel to flow into the cooling channel, the adsorption component adsorbs the electronic device, and the charging coil is arranged in the adsorption component, so that the wireless charging and cooling of the wireless charging base and the electronic device can be realized at the same time, thereby avoiding the temperature of the electronic device being too high during charging, and improving the charging efficiency of the electronic device.

[0028] The wireless charging base 100 according to some embodiments of the present application will be described below. Figures 1-9 The wireless charging base 100 according to some embodiments of the present application will be described below.

[0029] As shown in Figure 1 and Figure 2 The wireless charging base 100 according to some embodiments of the present application includes a body 110, an adsorption component 120, a driving component 130 and a charging coil 140. The body 110 has a cooling channel 112 and an adsorption channel 114, the first end of the adsorption channel 114 communicates with the cooling channel 112; the adsorption component 120 is connected with the body 110, the second end of the adsorption channel 114 extends to the adsorption component 120; the driving component 130 can drive the medium in the cooling channel 112 to flow, and can drive the medium in the adsorption channel 114 to flow into the cooling channel 112, so that the adsorption component 120 can adsorb the electronic device 200; the charging coil 140 is arranged in the adsorption component 120, and can charge the electronic device 200 adsorbed on the adsorption component 120.

[0030] In the embodiment of the present application, the wireless charging base 100 comprises a body 110, an adsorption component 120, a driving component 130 and a charging coil 140. The body 110 has a cooling channel 112 and an adsorption channel 114, the first end of the adsorption channel 114 communicates with the cooling channel 112; the adsorption component 120 is connected with the body 110, and the second end of the adsorption channel 114 extends to the adsorption component 120 to realize the installation of the adsorption component 120 on the body 110. The driving component 130 can drive the medium in the cooling channel 112 to flow, and can drive the medium in the adsorption channel 114 to flow into the cooling channel 112. Since the driving component 130 generates strong positive pressure airflow when working, the medium in the adsorption channel 114 is driven to flow to one side of the cooling channel 112, so that negative pressure is generated in the adsorption channel 114, and the adsorption component 120 can adsorb the electronic device 200 under the action of the negative pressure, so that the electronic device 200 and the body 110 can be fixed together, and the medium flowing in the cooling channel 112 can cool the electronic device 200 and the wireless charging base 100. The charging coil 140 is arranged in the adsorption component 120 to realize the installation and fixation of the charging coil 140, so that when the adsorption component 120 is adsorbed with the electronic component, the charging coil 140 can charge the electronic device 200, thereby realizing the wireless charging of the electronic device 200.

[0031] According to the wireless charging base 100 of the embodiment of the present application, the medium in the cooling channel 112 is driven to flow by the driving component 130, the medium in the adsorption channel 114 is driven to flow into the cooling channel 112, the adsorption component 120 adsorbs the electronic device 200, and the charging coil 140 is arranged in the adsorption component 120, so that the wireless charging can be performed while the wireless charging base 100 and the electronic device 200 are cooled, thereby improving the charging efficiency of the electronic device 200.

[0032] Optionally, the adsorption base can be a suction disc made of silica gel, and the charging coil 140 is fixed in the suction disc. When the adsorption channel 114 is under negative pressure, the suction disc is adsorbed and fixed on the surface of the electronic device 200.

[0033] Optionally, the electronic device 200 is a mobile phone, a tablet computer, a display or a vehicle-mounted display screen, so that the above-mentioned devices can be wirelessly charged and cooled at the same time.

[0034] Optionally, when wireless charging of the electronic device 200 is required, the driving component 130 rotates at high speed after being powered on (or the switch is turned on), generating strong positive air flow, and air flows rapidly along one side of the cooling channel 112 and then is discharged from the other side of the cooling channel 112. In this process, due to the principle of the vacuum generator, negative pressure is generated in the adsorption channel 114, and the adsorption component 120 can adsorb the electronic device 200 under the action of the negative pressure, so that the electronic device 200 can be fixed with the body 110 (this process is relatively short and can be completed in less than 1 second). During the operation of the driving assembly, air flows rapidly on the side of the electronic device 200 close to the driving component 130 and the cooling channel 112, thereby dissipating the heat of the motor 134 and the wireless charging base 100, achieving the purposes of fixing the wireless charging base 100 and dissipating heat. When wireless charging is not required, the driving component 130 can be stopped by turning off the power or the switch, so that the normal air pressure in the adsorption channel 114 is restored, and the wireless charging base 100 or the electronic device 200 can be easily removed.

[0035] Optionally, the present application can dissipate heat from the mobile phone and the wireless charging base 100 when the mobile phone or the tablet and other vehicle-mounted electronic devices 200 are wirelessly charged, avoiding the repeated use of heat dissipation back clamps and the energy loss and heating problems of the magnet wireless charging base. The user can easily remove the wireless charging base through the switch, thereby improving the user experience.

[0036] Optionally, the wireless charging base 100 of the present application can be modularly increased in number to achieve the effect of actual heat dissipation and the like.

[0037] Optionally, as shown in Figure 3 and Figure 4 , the present application uses the principle of the vacuum generator. The vacuum generator is generally suitable for the suction of objects with a weight of 30 kg or less. The main principle is that, according to the continuity equation of incompressible air gas (the gas can be approximately considered as incompressible air at low speed), A1×v1=A2×v2.

[0038] A1×v1=A2×v2

[0039] In the formula, A1 is the cross-sectional area of the cooling channel 112, A2 is the cross-sectional area of the adsorption channel 114, and the units of A1 and A2 are m 2 ;

[0040] v1 is the air flow velocity of the cooling channel 112, and v2 is the air flow velocity of the adsorption channel 114. The units of v1 and v2 are m / s.

[0041] As can be seen from the above formula, the cross-sectional area increases and the flow velocity decreases; the cross-sectional area decreases and the flow velocity increases.

[0042] For the horizontal pipe, according to the Bernoulli ideal energy equation of incompressible air:

[0043] P1+(1 / 2)×ρ×v1 2 =P2+(1 / 2)×ρ×v2 2

[0044] wherein P1 is the corresponding pressure of the cross section A1, P2 is the corresponding pressure at the cross section A2, the units of P1 and P2 are Pa;

[0045] v1 is the flow velocity of the cooling channel 112, v2 is the flow velocity of the adsorption channel 114, the units of v1 and v2 are m / s;

[0046] ρ is the density of air, the unit of ρ is kg / m 3 ;

[0047] According to the above formula, the flow velocity increases and the pressure decreases, when v2>v1, P1>P2. When v2 increases to a certain value, P2 will be less than one atmosphere, that is, negative pressure is generated. Therefore, the flow velocity can be increased to obtain negative pressure and generate suction force.

[0048] According to some embodiments of the present application, the cooling channel 112 includes a first sub-channel 1122, a second sub-channel 1124 and a third sub-channel 1126; the second sub-channel 1124 is located between the first sub-channel 1122 and the third sub-channel 1126; the cross-sectional areas of the first sub-channel 1122 and the third sub-channel 1126 are both greater than the cross-sectional area of the second sub-channel 1124; the adsorption channel 114 communicates with the cooling channel 112 through the second sub-channel 1124.

[0049] In the embodiments of the present application, the cooling channel 112 comprises a first sub-channel 1122, a second sub-channel 1124 and a third sub-channel 1126. The second sub-channel 1124 is located between the first sub-channel 1122 and the third sub-channel 1126; the adsorption channel 114 communicates with the cooling channel 112 through the second sub-channel 1124, i.e. the first end of the second sub-channel 1124 is connected with the first sub-channel 1122, and the adsorption channel 114 is connected with the second sub-channel 1124; the third sub-channel 1126 is connected with the second end of the second sub-channel 1124, so that the adsorption channel 114 communicates with the first sub-channel 1122, the second sub-channel 1124 and the third sub-channel 1126. The cross-sectional area of the first sub-channel 1122 and the third sub-channel 1126 is greater than that of the second sub-channel 1124, so that the cross-sectional area of the second sub-channel 1124 is small, and thus the flow rate of the medium in the second sub-channel 1124 increases and the pressure decreases to generate a negative pressure, so that the medium in the adsorption channel 114 flows into the cooling channel 112, thereby enabling the adsorption component 120 to adsorb the electronic device 200.

[0050] Optionally, the electronic device 200 is a mainboard area, a battery area and a tail plate area, and the wireless charging seat 100 is fixed in the battery area of the mobile phone, the first sub-channel 1122 faces the mainboard area of the electronic device 200, and the third sub-channel 1126 faces the tail plate area of the electronic device 200.

[0056] According to some embodiments of the present application, the driving component 130 is arranged outside the cooling channel 112, and the driving component 130 is in communication with the cooling channel 112 through the connecting pipe 150.

[0057] In the embodiments of the present application, the driving component 130 is arranged outside the cooling channel 112, and the driving component 130 is in communication with the cooling channel 112 through the connecting pipe 150. By arranging the connecting pipe 150, the positive pressure air flow generated by the high-speed rotation of the driving component 130 can be transmitted to the cooling channel 112 through the connecting pipe 150 for cooling, so that the driving component 130 can be located away from the electronic device 200, thereby reducing the volume and weight of the wireless charging base 100. Moreover, the driving component 130 can be located away from the electronic device 200, so that the user can operate the electronic device 200 more conveniently, and the noise generated by the operation of the driving component 130 can not be produced near the electronic device 200, thereby improving the user experience.

The first end of the adsorption component 120 is connected to the adsorption channel 114, and the second end of the adsorption component 120 is used to contact the electronic device 200. When the driving component 130 operates, a strong positive pressure airflow is generated, causing air to flow into the cooling channel 112. The airflow within the funnel shape flows from the first end of the adsorption component 120 into the adsorption channel 114 and is discharged from the cooling channel 112. During this process, due to the principle of a vacuum generator, the medium flows rapidly within the cooling channel 112, thereby generating a negative pressure within the adsorption channel 114. Since the second end of the adsorption component 120 is in contact with the electronic device 200, under the action of the negative pressure, the adsorption component 120 can be fixedly adsorbed onto the electronic device 200. Furthermore, the diameter of the first end is smaller than the diameter of the second end, increasing the adsorption area of ​​the adsorption component 120 on the electronic device 200 and enhancing its adsorption capacity.

The air inlet end of the cooling channel 112 faces the side where the mainboard of the electronic device 200 is located, so that when the driving component 130 works, the air flow on the side where the mainboard of the electronic device 200 is located can continuously flow into the air inlet end of the cooling channel 112, thereby taking away the heat generated by the mainboard of the electronic device 200, so as to achieve the purpose of heat dissipation of the electronic device 200.
