Problems solved by technology

Since traditional battery chargers and power converters need to be connected to batteries, a space must be left to accommodate the batteries when not in use. Even if the charging circuit and conversion circuit can be made smaller, the size of the charger is limited due to the above reasons. Miniaturization creates difficulties

Embodiment 1

[0035] Example one: such as Figure 5 Shown in is an example of a charger that uses an elastic band to fix a standard battery. This example corresponds to a charger that uses AC power to charge a standard battery. 21 is a power plug. The main body 22 and the bottom cover 27 are provided with a connecting groove 26. The elastic band 24 can connect the main body 22 and the bottom cover 27 together through the connecting groove. 20 is a circuit board in the main body, including electrodes and charging circuits. The battery 25 can be fixed between the main body 22 and the bottom case 27 by virtue of the elastic force of the elastic band 24 after the elastic band 24 is pulled. And make the battery electrode and the main body and the electrode on the bottom cover correspond. The main body 22 can be inlaid with a magnet 23, and the bottom cover 27 can be made of magnetic material. The main body and the bottom cover can be attracted together by magnetism when the charger is not in use, fo...

Embodiment 2

[0037] Embodiment two: such as Picture 9 Shown in is a schematic diagram of a multifunctional charger that uses AC power and USB to charge a rechargeable digital device battery with a power conversion function using elastic bands and a bottom cover. The charger main body 30 is connected to the bottom cover 36 by an elastic band 37. The internal structure design and electrode arrangement 39 of the main body and the bottom cover correspond to the digital device battery 35 that needs to be charged, and the digital battery 35 is placed in the main body 30 and Between the bottom cover 36, the battery and the charger are combined by the elastic force generated by stretching the elastic band 37. The foldable AC power plug 31 can be stacked in the reserved slot 32 when not in use. After being connected to the AC power source through the power plug 31, the internal circuit of the charger can output a suitable charging voltage to charge the digital battery 35. It is also possible to use th...

Embodiment 3

[0039] Example three, such as Figure 13 In order for the charger to directly use the elastic belt to connect the battery without using the bottom cover, the original connection groove on the main body 30 is changed from the two sides of the main body to the side object middle position 322. The elastic belt 321 does not need to be connected to the bottom cover 36 and directly connects the battery 35 and The main body 30 is fixed together. Such as Figure 14 A variation of this embodiment, 330 is an example of a charger with a magnetic bracket 332 on the elastic band 331 instead of the bottom cover 36. The bracket 332 is attached to the elastic band 331, and the width of the metal bracket 332 is the same as the thickness of the battery. Correspondingly, it can be more conducive to the combination of the battery and the main body. Figure 15 An example diagram of a charger with a bracket 332 instead of the bottom cover 35 that uses a retractable USB interface and uses USB power to cha...

Abstract

The invention relates to a novel battery charger and power converter structure using an elastic belt to fix the battery. The novel structure is composed of a charger and power converter main body, a separable charger and power converter bottom frame, and one or more elastic belts made of an elastic material and capable of generating elastic force through tensile deformation, wherein the charger and power converter main body is connected with the bottom frame through the elastic belts. Batteries can be arranged between the main body and the bottom frame after the elastic belts are stretched, and the batteries can be bonded with the main body by the elastic force generated by the stretched elastic belts so as to ensure the contact between the battery electrodes and the electrode points on the main body. Alternatively, the batteries can be directly bonded with the main body through the main body and the elastic belts without the need of a bottom cover. The novel structure can on longer keep the battery accommodating space when the charger or power converter is not in use, thereby greatly reducing the space of the charger and the power converter, and facilitating use for customers.

Description

Technical field [0001] The present invention belongs to the related technical field of battery chargers and power converters, in particular to a battery charger and power converter using elastic bands to fix the battery. The battery is fixed on the main body of the charger and the power converter through the elastic band, which is convenient for reducing The carrying volume of a small charger. Background technique [0002] With the increasingly widespread travel and company business trips, people often need to carry a lot of digital devices, and the battery chargers of these devices also need to take up a lot of volume, which brings inconvenience to travel. When you are outside, you often encounter situations where the equipment you carry is out of power and strikes due to forgetting to charge or overuse. People also need to carry some small power converters to convert the easily purchased standard battery power to these digital devices. These converters will take up a lot of spa...
