Description

Technical Field

[0001] The invention relates to a vehicle-mounted wireless charging component, in particular to a novel air outlet component for a wireless dual-charging module. Background Art

[0002] At present, with the increasing requirements of users for charging convenience, car wireless chargers have gradually become standard equipment in cars. Car wireless chargers can reduce the use of traditional charging cables and avoid the problem of mismatch between different charging interfaces. When the car is running, users only need to place the mobile phone on the induction area of ​​the car wireless charger to charge the mobile phone, which improves the convenience of mobile phone charging and enhances the user's driving experience.

[0003] During the use of the car wireless charger, due to the high charging power and fast charging speed, the coil parts of the charger and the mobile phone will generate heat. When the heat accumulates and the temperature rises, the charging efficiency will decrease, and the aging and even damage of the electronic components in the car wireless charger and the mobile phone will be accelerated. Therefore, a heat dissipation device is usually provided in the car wireless charger.

[0004] There is a high-power dual-charge wireless charging module, which consists of a shell, a wireless charging component and a fan. Figure 1 As shown, the upper surface of the shell is the charging area for placing mobile phones. The wireless charging component is located in the shell below the charging area. The fan is located below the wireless charging component. An airflow channel connecting the fan and the charging area is provided in the shell. The upper side cover of the airflow channel is provided with a shielding member, which can constrain the airflow to flow to both sides, so that the airflow can blow to the charging areas on both sides to dissipate heat for the mobile phones in the charging areas and the shell. However, the air outlet of this product is in a normally open state. Although a shielding member is installed to make the air outlet have a certain hiding effect, it still cannot prevent the entry of foreign matter and dust; and there is no gear selection for blowing. When the customer only uses one side for charging, the airflow generated by the fan will still blow to both sides, causing the air volume to be dispersed and the air volume utilization rate to be low. Summary of the invention

[0005] The present invention provides a novel air outlet component for a wireless dual-charging module, which solves the problem in the prior art that the air outlet of the dual-charging wireless charging module is always open and the blowing direction cannot be controlled.

[0006] The above technical problems of the present invention are mainly solved by the following technical solutions: A new type of air outlet assembly for a wireless dual-charging module, comprising an upper shell, a lower shell and a fan module located at the lower side of the lower shell, wherein the upper shell and the lower shell cover each other and define a receiving cavity for installing the wireless dual-charging module, wherein an air duct running through the upper shell and the lower shell is provided in the receiving cavity, and the air duct is separated from the receiving cavity;

[0007] The upper shell is provided with an air duct baffle covering the upper opening of the air duct, and the air duct baffle is formed with air outlets opening to both sides, and the upper shells on both sides of the air duct baffle correspond to charging areas;

[0008] The air outlet end of the fan module is connected to the lower opening of the air duct; a lifting seat is movably provided on the upper side of the air duct, and the outer contour of the lifting seat is adapted to the inner contour of the air duct, and a left branch channel and a right branch channel separated from each other are formed in the lifting seat, so that the airflow at the lower side of the lifting seat can only reach the upper side through the two branch channels; a rotating body is provided in the air duct and below the lifting seat for horizontal rotation, and a stepping motor for driving the rotating body to rotate is provided in the accommodating cavity, and a horizontal wind grid plate is eccentrically provided on the rotating body, and the bottom outer contour of the lifting seat is adapted to the rotation path of the wind grid plate, and the lifting seat has no support in the air duct, and only the wind grid plate on the rotating body can play a supporting and limiting role;

[0009] The present invention is provided with four gears, each gear corresponds to a different rotation position of the rotating body, and corresponds to a plurality of different blowing modes, which are as follows:

[0010] The fan module does not work in the closed position, and the stepper motor drives the wind grid plate to rotate to a low position, so the lifting seat is also in a low position, and the upper openings of the left and right branch channels are both in a blocked state. At this time, the upper opening of the air duct is completely blocked by the lifting seat. Preferably, the top surface of the lifting seat at this time can be designed to be not lower than the upper surface of the upper shell through size design. Therefore, when the present invention is in this gear, the upper opening of the air duct is in a closed state, and dust and impurities from the outside are not easy to fall into the air duct;

[0011] Dual-channel gear, in which the stepper motor drives the wind grid plate to rotate to the middle position. During the process of the wind grid plate rotating from the low position to the middle position, the height of the wind grid plate will gradually rise, thereby pushing the lifting seat to gradually rise until the lifting seat is pushed to the high position by the wind grid plate. At this time, the upper openings of the left and right diversion channels are completely exposed, and the wind duct is connected to the two air outlets. Therefore, when the present invention is in this gear, the two charging areas can be cooled at the same time;

[0012] Right single-channel gear position, in which the stepper motor drives the wind grid plate to rotate until the lower end opening of the left branch channel is completely blocked. At the same time, because the lifting seat at this stage abuts against the outer structure of the wind grid plate, and the rotation path of the outer structure of the wind grid plate is consistent with the bottom outer contour of the lifting seat, the height of the lifting seat no longer changes, and the lifting seat is still in a high position. When the present invention is in this gear position, only the right branch channel connects the air duct with the corresponding air outlet, realizing the right single-channel air outlet;

[0013] The left single-channel gear is similar to the right single-channel gear. When the stepper motor drives the wind grid plate to rotate to completely block the lower end opening of the right diversion channel, the lifting seat is still in a high position, and only the left diversion channel connects the air duct with the corresponding air outlet to realize the left single-channel air outlet.

[0014] Furthermore, a plurality of springs are connected between the top of the lifting seat and the air duct baffle. The spring rebound effect will give the lifting seat a certain pre-pressure, and will not jump up and down due to external vibration. At the same time, when the gear position of the present invention is switched, the lifting seat can be reliably lifted up and down without getting stuck.

[0015] Therefore, compared with the prior art, the present invention has the following characteristics: 1. A lifting seat that can move up and down is provided in the air duct. When the present invention is in the closed position, the lifting seat is in a low position, and the upper openings of the left branch channel and the right branch channel are in a blocked state. The upper opening of the air duct is completely blocked by the lifting seat, and external dust and impurities are not easy to fall into the air duct; 2. The present invention can switch gears according to the number and position of the customer's mobile phones, and can realize left-side single-channel ventilation, right-side single-channel ventilation and dual-channel ventilation. Especially in single-channel ventilation, compared with the prior art, the air volume and air volume utilization rate can be significantly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example 1: See Figure 2 , Figure 3 and Figure 5 A novel air outlet assembly for a wireless dual-charging module comprises an upper shell 100, a lower shell 200 and a fan module 300 located at the lower side of the lower shell. The upper shell and the lower shell cover each other and define a receiving cavity 400 for installing the wireless dual-charging module. The receiving cavity is provided with an air duct 500 that runs through the upper shell and the lower shell, and the air duct is separated from the receiving cavity. The cross section of the air duct is a long strip.

[0029] See Figure 4 The upper shell is provided with an air duct baffle 600 covering the upper opening of the air duct, and an air outlet 610 opening to both sides is formed on the air duct baffle. The air duct baffle divides the upper surface of the upper shell into a left charging area 110 and a right charging area 120. The upper surface of the upper shell can be provided with a concave air guide groove to guide the airflow blown out from the air outlet, so that the airflow can take away the heat of the mobile phone and the surface of the upper shell at the same time. The air guide groove is a prior art, so it is not repeated in this embodiment;

[0030] See Figure 6The air outlet end of the fan module is connected to the lower opening of the air duct; a lifting seat 700 is movably provided on the upper side of the air duct, and the outer contour of the lifting seat is adapted to the inner contour of the air duct. A left branch channel 710 and a right branch channel 720 separated from each other are formed in the lifting seat, so that the airflow under the lifting seat can only pass through the two branch channels to the upper side; a rotating body 800 is provided in the air duct and below the lifting seat for horizontal rotation, and a stepping motor 900 for driving the rotating body to rotate is provided in the accommodating cavity, and a horizontal eccentrically provided on the rotating body The wind grid plate 810 is provided on the rotating body, and a plurality of semicircular grid plates 820 which are concentric with the rotating shaft are provided on the rotating body. The wind grid plate and the semicircular grid plate are provided on the same side relative to the axis of the rotating body, and the outer contour of the wind grid plate is consistent with the contour of the semicircular grid plate. The lifting seat is provided with abutment grid plates 730 which are directly opposite to the semicircular grid plates above and below, and the bottom outer contour of the abutment grid plates is consistent with the arc contour of the semicircular grid plates. The lifting seat has no support in the air duct, and only the wind grid plates and the semicircular grid plates on the rotating body can play the role of support and limit.

[0031] This embodiment has four gears, each gear corresponds to a different rotation position of the rotating body, and corresponds to a variety of different blowing modes, as follows:

[0032] See Figure 6 , the closed gear, the fan module does not work in this gear, the stepper motor drives the wind grid plate to rotate to the low position, so the lifting seat is also in the low position, the upper openings of the left and right shunt channels are in a blocked state, and the upper opening of the air duct is completely blocked by the lifting seat. Preferably, the top surface of the lifting seat at this time can be designed to be not lower than the upper surface of the upper shell through size design, so when the present embodiment is in this gear, the upper opening of the air duct is in a closed state, and dust and impurities from the outside are not easy to fall into the air duct;

[0033] See Figure 7 , dual-channel gear, in which the stepper motor drives the wind grid plate to rotate to the middle position. During the process of the wind grid plate rotating from the low position to the middle position, the height of the wind grid plate will gradually rise, thereby pushing the lifting seat to gradually rise until the lifting seat is pushed to the high position by the wind grid plate. At this time, the upper openings of the left and right diversion channels are completely exposed, and the air ducts are connected to the two air outlets. Therefore, when this embodiment is in this gear, the two charging areas can be cooled at the same time;

[0034] See Figure 8 , right single-channel gear, in which the stepper motor drives the wind grid plate to rotate to completely block the lower end opening of the left branch channel. At the same time, because the lifting seat at this stage is in contact with the outer structure of the wind grid plate and the semicircular grid plate, and the outer sides of the wind grid plate and the semicircular grid plate are arcs, which are consistent with the bottom shape of the lifting seat, the height of the lifting seat no longer changes, and the lifting seat is still in a high position. When this embodiment is in this gear, only the right branch channel connects the air duct with the corresponding air outlet to achieve single-channel air outlet on the right side;

[0035] See Fig. 9 , the left single-channel gear is similar to the right single-channel gear. When the stepper motor drives the wind grid plate to rotate to completely block the lower end opening of the right diversion channel, the lifting seat is still in the high position, and only the left diversion channel connects the air duct with the corresponding air outlet to realize the left single-channel air outlet.

[0036] See Figure 6 A plurality of springs 620 are connected between the top of the lifting seat and the air duct baffle. The spring rebound effect will give the lifting seat a certain pre-pressure, and it will not jump up and down due to external vibration. At the same time, when the gear is switched in this embodiment, the lifting seat can be reliably lifted up and down without getting stuck.

[0037] See Fig.10 A plug-in slot 210 is provided on the lower shell and located at the lower opening of the air duct, and a clamping slot 220 is provided on both side walls of the plug-in slot. A plug-in portion 310 matching the plug-in slot is provided at the air outlet end of the fan module, and elastic wedge-shaped clamping blocks 320 that can be engaged with the clamping slot are provided on both sides of the plug-in portion. In this way, the fan module can be quickly disassembled and assembled with the plug-in slot.

[0038] See Figure 3 The rotating body is also provided with a core rod 830 coaxial with its rotating shaft, and the core rod can enhance the bending and torsional strength of the rotating body.

[0039] The present invention can be modified in various ways which are obvious to those skilled in the art, and such modifications are not considered to depart from the scope of the present invention. All such modifications which are obvious to those skilled in the art are intended to be included within the scope of the present claims.
