Description

Portable equipment support

Technical Field

The application relates to the field of energy storage devices, in particular to a portable device support.

Background

With the rapid development of science and technology culture, in the daily life of people, various portable devices (such as mobile phones, tablet computers, game machines and the like) are more and more widely applied, and the influence is more and more important. Supporting frame devices have also been developed, which are usually provided with retractable arms, and which are used to attach or detach a portable device by extending or retracting the arms.

Portable device holders currently on the market typically employ batteries as the power source. Unfortunately, the battery is easy to burn and even explode, so that a plurality of potential safety hazards are added to the vehicle-mounted mobile phone support; in addition, the battery needs to be subjected to safety test certification and can be applied to the portable equipment support, so that the production cost is increased.

Disclosure of Invention

The inventor researches the reason of potential safety hazard of the portable equipment bracket, and finds that: the internal space and structure of the existing portable equipment support are very compact, too many devices can not be arranged in the portable equipment support to protect the battery due to the limitation of space, when the internal battery is excessively extruded due to collision, impact or other conditions in the ordinary portable equipment support used by a user, the battery has very small probability of causing short circuit, once the battery is short-circuited, the battery can generate a large amount of heat in a short time in the charging and discharging process, and because the battery is arranged in a narrow space, the generated heat can not be timely diffused, so that the temperature of the battery is rapidly increased, meanwhile, electrolyte components (propylene carbonate, ethylene carbonate and dimethyl carbonate) in the battery are extremely combustible substances, so that the battery is very easy to combust and even explode in the short circuit, and the portable equipment support shell is also made of combustible organic high polymer materials, the battery burn may cause the portable device holder to burn entirely. Therefore, the potential safety hazard of the portable equipment support is caused by the potential safety hazard of the battery.

Secondly, just because the battery itself has a combustion hidden trouble, each country stipulates that the product with the battery needs to perform various safety test certifications on the battery before entering the market of the country, and the safety test items include but are not limited to: high simulation, high and low temperature cycle, vibration test, impact test, overcharge test, forced discharge and the like. The portable equipment support is just a product with a battery, so that the portable equipment support is required to meet local regulations when international trade is carried out, and particularly, the battery in the portable equipment support is required to pass local safety certification, so that the portable equipment support can be allowed to enter a local market. Such as CE certification in the european union region, FCC certification in the united states, PSE certification in japan, KC certification in korea, etc., it is required that the portable device cradle should be subjected to one security certification before entering the market of each country, which increases the cost of the battery, which results in an increase in the cost of the portable device cradle. Although there are some international common certification systems, such as CB certification, which is a global mutual certification system for electronic products operated by IECEE, and the member countries in the CB certification system mutually approve the test results, not all countries in the world approve CB certification, and only 47 countries presently approve CB certification, when the portable device cradle wants to enter the market of countries outside the CB certification system, there is also a problem of high cost of the portable device cradle.

In summary, the present application aims to provide a portable device holder to solve the aforementioned problems, and more particularly, the problems to be solved by the present application are: how to eliminate the potential safety hazard of portable equipment support, reduce the cost of portable equipment support simultaneously.

Specifically, the method is realized by replacing a battery with a super capacitor as a power source of the portable equipment support. Furthermore, the application is realized by the following technical scheme:

a super capacitor for use as a power source for the portable device holder.

Compared with a battery, when in short circuit, the discharge current of the super capacitor is changed exponentially, the discharge current is very high at the moment of short circuit, and then the discharge current is rapidly reduced, so that the super capacitor cannot generate a large amount of heat in a short time when in short circuit, the hidden danger of burning of the super capacitor is eliminated, and the potential safety hazard of the portable equipment support is eliminated. Meanwhile, the super capacitor does not need safety certification, and the cost is reduced.

In some embodiments, the portable device holder further comprises:

and the solar panel is used for charging the super capacitor.

In some aspects, the super capacitor is disposed inside the portable device holder.

In some embodiments, the portable device holder further comprises:

a circuit board; and

the motor is electrically connected with the circuit board and used for driving the portable equipment support to implement power transmission work;

wherein the super capacitor is electrically connected with the circuit board.

The super capacitor, also called electrochemical capacitor, electric double layer capacitor, gold capacitor, farad capacitor is an electrochemical element that has been developed in the seventh and eighties of the last century and stores energy by means of a polarized electrolyte. It is different from traditional chemical power source, and is a power source with special performance between traditional capacitor and battery, and mainly depends on electric double layer and redox pseudo-capacitance charge to store electric energy. But no chemical reaction occurs in the process of energy storage, and the energy storage process is reversible, and the super capacitor can be repeatedly charged and discharged for tens of thousands of times.
