Description

Technical Field

[0001] The invention relates to a storage box type wireless charging system and method, and belongs to the field of vehicle-mounted wireless charging equipment for engineering machinery. Background Art

[0002] In construction machinery such as excavators, there are usually USB charging ports, but the charging cables are easily bent and dusty in the cab, which often affects the effectiveness of charging. Wireless charging devices do not require charging cables, so charging is more convenient and quick.

[0003] There are two main types of existing wireless charging devices. One is a car charging box, which places the wireless charging module in the storage box of the original car to save space and facilitate the placement of mobile phones. The other is a bracket-type wireless charging, which allows the mobile phone interface to be seen during charging, but its installation requires space and sometimes affects the driver's line of sight.

[0004] The disadvantage of the current car charging box is that the mobile phone cannot be charged after the key switch of the vehicle is turned off; to prevent other electrical appliances from over-consuming the power of the starting battery after the key switch is turned off, other electrical appliances are also recommended to be used less. After the whole car is powered off, there is no emergency lighting. There are certain limitations in user experience and functionality. Summary of the invention

When the vehicle stops or the whole vehicle is powered off, the mobile phone can be wirelessly charged; the controller is installed at a suitable position in the cab, the controller is electrically connected to the wireless charging device, and CAN communication is performed to realize data transmission and control; the relay is electrically connected to the controller and the interior light on the whole vehicle, respectively, and the interior light is also electrically connected to the wireless charging device through the wiring harness assembly. When the vehicle stops or the whole vehicle is powered off, the controller outputs a signal to make the relay work, and when the interior light switch is turned on, the interior light is illuminated.

[0025] The specific structure of the wireless charging device is further described below.

[0026] like Figure 2 As shown, the wireless charging device is installed in the cab, for example, on the right hand side of the operator, for charging mobile phones and powering interior lights. The wireless charging device includes a PCB control board 1, a storage box body 2, a mobile phone silicone protective sheet 3, a cover 4, a limit silicone cover 5, a power indicator component 7, a protective cover 8, a wireless charging module 10, an energy storage module 11, and a wiring harness component 12.

[0027] The top surface of the storage box body 2 is open for holding the mobile phone 6 when charging, and a small hole is opened at the bottom of the storage box body 2 to facilitate timely outflow when water enters. The upper part of the storage box body 2 has a buckle structure, which can be firmly stuck on the interior panel of the vehicle cab to prevent the storage box body 2 from shaking up and down when the vehicle vibrates during operation.

[0028] The wireless charging module 10 is installed at a window opened in the upper area of ​​the side of the storage box body 2 , and is an electromagnetic coil used for wirelessly charging the mobile phone 6 .

[0029] The energy storage module 11 is installed in the lower area of ​​the side of the storage box body 2, and is used to store the electrical energy generated by the generator. When the vehicle is out of power, it provides power to the mobile phone 6 and the interior lights; the energy storage module 11 is a lithium battery or other energy-storing storage element, and is wrapped with explosion-proof material.

[0030] The PCB control board 1 integrates electronic components and is used for detection, control and protection functions of the wireless charging device.

[0031] The power indicator component 7 is used to display the remaining power of the wireless charging device and the fault alarm; in normal state, the remaining power value of the charging device is displayed, and when there is a fault, the value disappears and the indicator light flashes.

[0032] The protective cover 8 is usually made of stainless steel and is fixed to the side of the storage box body 2 by a plurality of screws 9 to protect the PCB control board 1, the energy storage module 11 and the wireless charging module 10. The stainless steel cover is integrally formed, has a large heat conduction area, and is conducive to heat dissipation.

[0033] The mobile phone silicone protective sheet 3 is arranged at the window on the side of the storage box body 2, and is made of silicone to protect the mobile phone 6 and the wireless charging module 10 during charging.

[0034] The cover 4 and the limiting silicone cover 5 are integrated and installed at the top opening of the storage box body 2; a slender rectangular hole is opened above the limiting silicone 5 to facilitate the insertion and removal of the mobile phone 6 and to stabilize the mobile phone on the top. The limiting silicone cover 5 can be turned 90 degrees to facilitate opening and cleaning of debris.

[0035] The wiring harness assembly 12 is composed of wires and connectors and is the transmission interface of the wireless charging device.

[0036] It should be noted that the interior lights are generally installed on the top of the cab or on the pillars of the cab for working lighting or emergency lighting at night. The relay consists of a coil and a normally open contact. The coil is electrically connected to the controller. The normally open contact is connected in series in the line connecting the wireless charging device and the interior lights on the vehicle. When the vehicle stops or the vehicle is powered off, the controller outputs a signal to close the normally open contact.

[0037] The specific control logic is as follows: When the vehicle is operating normally, the generator on the vehicle supplies power to all electrical components of the vehicle and also charges the wireless charging device. When the power level displays 100, the controller disconnects the charging of the energy storage module to prevent overcharging of the energy storage module. At this time, the mobile phone can be charged normally in the wireless charging device.

[0038] When the vehicle is shut down or the entire vehicle is powered off, the wireless charging device has residual power and can charge the mobile phone; at the same time, the power for the interior lights also comes from the wireless charging device, and the controller outputs a signal to make the relay work. When the interior light switch is turned on, the lighting can be normal.

[0039] In summary, the present invention provides a storage box type wireless charging system and method, which achieves the following functions and effects: (1) The buckle design of the storage box of the wireless charging device and the silicone design of the cover make it easy to put the phone in and out and prevent the phone from shaking up and down when the vehicle vibrates. The limited silicone cover can be flipped 90 degrees, which is convenient for opening and cleaning.

[0040] (2) The energy storage module of the wireless charging device is wrapped with explosion-proof material and can be used safely in the car.

[0041] (3) When the excavator stops or the entire vehicle is powered off, the wireless charging device can still charge the mobile phone if there is residual power.

[0042] (4) When the excavator stops or the entire vehicle is powered off, if there is any remaining power in the wireless charging device, it can be used to power the interior lights for emergency lighting, which is convenient and quick to use.
