Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging, and in particular to a wireless charging platform. Background Art

[0002] Wireless charging technology has been increasingly used in mobile phones. As wireless charging has become a trend, eliminating wired charging has become a trend. However, the problem of low charging efficiency has seriously affected its development. The wireless charging standard currently used in the industry is Qi, and its maximum charging power is 15W, which is similar to Qualcomm's QC2.0 fast charging specification. However, Qualcomm's wired fast charging technology has developed to QC4+, with a maximum power of 60W. The reason is that wireless charging uses inductive charging technology, which generates a certain current in the secondary coil through electromagnetic induction, thereby transferring energy from the transmission end to the mobile phone. Therefore, users must place the device on a special charging pad. If the induction coil inside the device and the coil on the charging pad are not aligned, it will lead to low efficiency. Therefore, we designed a wireless charging pad that can automatically align.

[0003] In order to solve the above technical problems, the existing Chinese patent publication number is CN211481009U, which is an automatically aligned wireless charger, comprising a device body, the device body is disc-shaped and the side wall of the device body is provided with a charging connection terminal, the inside of the device body is provided with a track disk corresponding to the charging induction disk, the track disk is provided with criss-cross coil moving guide rails, the coil moving guide rails are also provided with a charging cable reel, and the bottom of the charging cable reel is also provided with a general controller, a positioning platform, a steering wheel assembly and a steering wheel assembly, the general controller is electrically connected to the power connection terminal, the two ends of the positioning platform are symmetrically provided with drive motors, and the output shafts of the drive motors are provided with drive wheel assemblies. The utility model determines the position of the mobile phone receiving coil through the sensor on the charging induction disk, thereby determining the best charging position according to the output power, and directs the drive motor to drive the charging coil to move to the place with the highest charging efficiency through the single-chip microcomputer to achieve the best charging effect.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0034] Reference Figure 1-7 A wireless charging platform includes a shell component 3, a power supply mechanism is installed in the shell component 3, a charging trolley component 2 is installed in the shell component 3, the charging trolley component 2 and the power supply mechanism are connected, and the power supply mechanism can provide power to the charging trolley component 2, so that the charging trolley component 2 can automatically find the components to be charged to realize the charging operation.

[0035] Reference Figure 1 , 3 The power supply mechanism includes an AC-DC power supply component 1 installed in a housing component 3. A conductive plate component 4 is installed in the housing component 3. The conductive plate component 4 is composed of metal electrodes with positive and negative intervals in each direction. The positive and negative electrodes are arranged at intervals, so that the conductive wheel 23 has a high probability of contacting the positive and negative electrodes to achieve the transmission of electrical energy. The conductive plate component 4 conflicts with the conductive wheel 23 and the universal wheel component 24.

[0036] Reference Figure 1-7 The charging trolley assembly 2 is composed of a movable trolley housing 21, a wireless charging coil assembly 25, a PCB board assembly 27, a battery assembly 28, a plurality of universal wheel assemblies 24, a plurality of motor assemblies 22 and a plurality of conductive wheels 23, and the plurality of conductive wheels 23 are connected to the power supply mechanism. The PCB board assembly 27, the battery assembly 28, a plurality of universal wheel assemblies 24, a plurality of motor assemblies 22 and a plurality of conductive wheels 23 are all arranged in the movable trolley housing 21, and the wireless charging coil assembly 25 is arranged at the upper end of the movable trolley housing 21. The detection sensor assembly 26 can detect whether the charging trolley assembly 2 has moved to the limit position to save time to judge whether the charging trolley assembly 2 is to move in the opposite direction. The battery assembly 28 can also use a supercapacitor. If the charging trolley assembly 2 is just in a position where the conductive plate assembly 4 is not in contact, it can also move a certain distance in the state of the battery assembly 28 to achieve the purpose of re-contacting the conductive plate assembly 4. The motor assembly 22 can use a stepper motor or a DC motor with an encoder, which can more accurately walk and find the position of the mobile phone to be charged.

[0037] Reference Figure 4-7, multiple conductive wheels 23 are respectively installed on the output shafts of multiple motor assemblies 22, and multiple conductive wheels 23 are evenly divided into two groups. The motor assembly 22 can drive the conductive wheels 23 to rotate. The evenly divided conductive wheels 23 can fully ensure that the movable trolley shell 21 can move smoothly. The two groups of conductive wheels 23 are respectively arranged on opposite sides of the movable trolley shell 21. One end of the universal wheel assembly 24 penetrates the movable trolley shell 21 and extends into the shell assembly 3. Multiple detection sensor assemblies 26 are installed in the movable trolley shell 21; a battery assembly 28 is installed in the movable trolley shell 21, and the battery assembly 28 is connected to the corresponding components in the movable trolley shell 21 to provide electrical energy as needed. The battery assembly 28 can store a certain amount of electrical energy. When the conductive plate assembly 4 cannot be energized, the battery assembly 28 can intermittently function, so that the charging trolley assembly 2 can move and find the conductive plate assembly 4 to achieve electrical energy connection.

[0038] In the utility model, during actual production and preparation, the conductive wheel 23 and the universal wheel assembly 24 in the charging trolley assembly 2 are in contact with the conductive plate assembly 4 below. The conductive plate assembly 4 is a PCB board with alternating positive and negative poles. When any one (or both) of the conductive wheel 23 and the universal wheel assembly 24 is in contact with the conductive plate assembly 4, electrical energy can be obtained from the conductive plate assembly 4.

[0039] When working, the charging cart assembly 2 can scan the entire plane of the shell assembly 3. During the scanning process, the wireless charging coil assembly 25 communicates with the mobile phone. If it reaches a certain position and communicates with the mobile phone, charging can be carried out. It can be moved slightly to the side and the position can be adjusted to achieve maximum charging efficiency. By detecting the charging current, it can be known which position has the highest charging efficiency.

[0040] During operation, when the charging cart assembly 2 is in a state where the conductive wheel 23 and the universal wheel assembly 24 cannot contact any pair of positive and negative electrodes in the conductive plate assembly 4, the charging cart assembly 2 is powered by the built-in battery assembly 28 and can move. If it does not contact, it will try again after a while, and no continuous retry will be performed. Because there is a possibility that the entire shell assembly 3 is not connected to the power supply, if so, the power in the battery assembly 28 will be exhausted quickly, and it can only be retried once after a period of time to save the stored power. If the entire shell assembly 3 has not been connected to the power supply during storage, and the power stored in the battery assembly 28 in the charging cart assembly 2 is completely exhausted, when the power is turned on, the user can tip the shell assembly 3, and the charging cart assembly 2 will move under the action of gravity. As long as it moves, it will re-contact the positive and negative electrodes of the conductive plate assembly 4, so that the charging cart assembly 2 can regain power. The conductive wheel 23 of the charging cart assembly 2 is also a driving wheel, which can drive the charging cart assembly 2 to perform a full scan in the X and Y directions within the entire housing assembly 3, so the mobile phone can be placed on the housing assembly 3 at will to complete charging.

[0041] After a mobile phone is charged, the charging cart assembly 2 will continue to move to scan the next mobile phone, so there can be multiple mobile phones on the shell assembly 3, and multiple mobile phones can be charged overnight. During use, of course, the total charging time of each mobile phone cannot exceed the length of one night.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
