Description

Modularized wireless charging device and device with wireless charging expansion function

Technical Field

The utility model relates to a wireless charging technology field especially relates to a wireless charging device of modularization and have wireless extended function's of filling device.

Background

Currently, with the increasing development of 5G, internet of things, cloud computing and artificial intelligence, the human society is accelerating to enter the era of mobile internet of things. And each scene of human life will be intelligentized day by day, and the interconnection of everything will lead to many objects (terminals) that do not need electric energy supply originally, produce information exchange and energy supply. As the number of interconnection terminals is increased, the number of energy supply methods is also increased. Most mobile terminals are inevitably non-ported due to product design, safety and other considerations, so that wireless charging becomes an important implementation mode of energy supply in the era of mobile internet of things.

The wireless charging device mainly comprises a control circuit board and a transmitting coil. The existing wireless charging device mainly has two solutions, wherein the first design scheme is that a control circuit board and a transmitting or receiving coil are arranged in the same shell, and the control circuit board and the transmitting coil are welded together; the second design scheme is that the control circuit board and the transmitting or receiving coil are respectively arranged in two independent shells and fixedly connected through a connecting wire, namely two ends of the connecting wire are respectively welded on the control circuit board and the transmitting coil.

These two kinds of solutions, all be with the subassembly fixed connection of wireless charging scheme together, all have the shortcoming in concrete application, embody specifically:

1) because the main control board and the coil of the wireless charging are combined together in a fixed connection mode, when a terminal with a wireless charging function is designed, sufficient space must be reserved for the wireless charging device in advance, safety problems such as heat dissipation, electricity leading insulation and the like need to be considered, and the difficulty and the cost of the design are improved; in the manufacturing process, the whole wireless charging device is preset, so that the manufacturing cost required by presetting the wireless charging function is increased. Most importantly, under the condition that the prospect of whether the wireless charging function is needed in a terminal and an application scene is not clear, the preset of the wireless charging function can be ignored by most product designers and manufacturers, and therefore the application and popularization of the future wireless charging scene and function are influenced. Due to the increasing popularization of wireless charging function terminals and application scenarios, the expansion and upgrading of the wireless charging function of related products will certainly require the whole upgrading of the terminal or the scenario, thereby causing the waste of a large amount of social resources and bringing unnecessary resistance and cost to the popularization of various application scenarios and terminals. If the wireless charging function or component can be preset at low cost and the expansion of the wireless charging function can be flexibly and rapidly realized, huge economic benefits and social benefits are brought to the development of the whole society.

2) In the product developed by the first design scheme and the second design scheme, because the control circuit board cannot be replaced independently, the receiving end (such as a mobile phone, a mobile phone accessory, a tablet, a notebook computer and the like) and the transmitting end (such as a wireless charger) cannot be compatible or cannot work in cooperation with the maximum charging power of the receiving end due to the upgrade of the power of the load or the wireless charging technology and protocol. Products which are produced by a manufacturer and purchased by a user cannot meet the updating and updating requirements of the latest receiving terminal products, so that the user experience is quickly reduced and great social resources are wasted; due to the fact that the iteration of the product of a manufacturer involves the change of a control circuit board, the whole product is required to be subjected to mold opening, debugging and production again, the development period is long, the development cost is high, and the risk of new product development is high. Therefore, how to flexibly expand and rapidly, safely and inexpensively upgrade the wireless charging function is also a main factor limiting the development of the wireless charging industry.

3) The first solution sets up control circuit board and transmitting coil in same casing, because control circuit board and transmitting coil's calorific capacity is great, and the restriction of casing volume less or structure, it is not good to lead to wireless charging device's radiating effect, consequently, wireless charging device's charge efficiency has been reduced, lead to wireless charging device to produce the slow problem of charging, especially when powerful quick wireless charging, change and produce the bad condition of serious heat dissipation, the burning can take place even, the explosion, increase the potential safety hazard.
