Description

A multifunctional suitcase

technical field

The invention belongs to the field of travel devices, in particular to a suitcase with multiple functions.

Background technique

With the rapid development of society and technology, transportation is more convenient, and the popularity of outbound travel is getting higher and higher. In 2014, the market size of my country's suitcase industry reached 14 billion yuan. In 2015, the market size of my country's suitcase industry is expected to exceed 15 billion yuan. . It can be seen that suitcases have become an indispensable must-have for travelers. However, for most travelers, luggage is not easy to carry, and they always move forward with a heavy burden, which not only delays time, but also destroys the good mood of travel.

The suitcases currently on the market have almost no other functions except for loading clothes and other supplies, and their functions are too single to meet the needs of consumers. In the era of advanced electronic products, ordinary suitcases cannot meet people's requirements for charging electronic products. During long-distance travel, because of the dragging process of the suitcase, it will lead to loss of interest in travel, because the electronic equipment runs out of power, and the beautiful scenery will be missed. As well as precious memories, it is becoming more and more important to give suitcases more practical functions.

Contents of the invention

In order to overcome the shortcoming that the function of suitcases in the market is too single, the present invention provides a multifunctional suitcase. The technical solution adopted by the present invention to solve its technical problems is:

A multifunctional suitcase, comprising a box body, a skateboard device arranged at the rear and lower part of the box body, a brake pedal device arranged on the skateboard device, a telescopic pull rod arranged at the rear of the box body and a Solar panel installation directly above the cabinet.

The skateboard device includes a skateboard connected to the box through a hinge, a front pulley hub shaft of the skateboard arranged under the skateboard close to the box body, a front pulley hub of the skateboard sleeved on the front pulley hub shaft of the skateboard, and a skateboard arranged at the rear end of the bottom of the skateboard. Rear pulley hub shaft, the skateboard rear pulley hub that is sleeved on the skateboard rear pulley hub shaft, the brake pedal that is installed on the top of the skateboard rear pulley hub and connected to the skateboard, the spring support frame that is connected to the skateboard through a hinge, and the support The support plate pull bar that links to each other and the spring that links to each other with support plate.

The telescopic pull rod is connected with the box body;

The telescopic pull rod is arranged at the rear of the box body, which can realize the functions of lifting the box body and sliding support.

When the skateboard is put down, the skateboard and the pull rod are at an angle of 90 degrees, and the skateboard device can be retracted by pulling the support plate pull rod. When the skateboard is put away, the skateboard and the pull rod are in a 0-degree parallel state.

The brake pedal is installed above the rear pulley hub of the skateboard and connected with the skateboard through a hinge. Its shape is arched, and its surface is covered with raised anti-skid lines that increase friction. When using it, you only need to step on the brake pedal with your feet.

The solar panel device includes a foldable support frame connected to the box through a hinge, a solar panel connected to the foldable support frame through a hinge, a cover plate connected to the box body through a hinge, and a lock connected to the cover plate through a hinge. The cover, the lock connected with the box body, the battery charging board connected with the solar panel through the wire, the battery connected with the battery charging board through the wire, and the USB interface arranged on the box body are connected with the battery through the wire.

The working process of the solar panel device is:

The solar panel converts the received sunlight into electrical energy, and transmits it to the battery charging board through the wires. After being processed by the battery charging board, the electrical energy is stored in the battery through the wires through the battery protection board. The battery protection board is used for charging. , to protect the battery from voltage and current damage.

When the electronic equipment needs power, the electronic equipment can be connected with the USB interface on the cabinet through the USB cable. The electric energy is output to the USB interface through the battery protection board, the battery booster board, and the rectifier module through the wire, and then reaches the electronic equipment.

The power indicator board of the battery is connected to the rear end of the battery protection board through wires, and is connected in parallel with the power output circuit. There are 3-12 LED lights on the power indicator board, which are used to display the storage capacity of the battery, according to the number of lights on. How much power is stored in the battery.

The beneficial effects of the present invention are: the function of the skateboard reduces the load of the traveler, and the skateboard can be stepped on to slide, which also increases the fun of the journey. At the same time, the traveler can also place other items in the middle of the skateboard; the brake device can make the suitcase Efficient and safe stop; solar panels can charge electronic products and store the electricity converted from solar energy in the battery, which can also supply power when there is no light. The whole device is green and environmentally friendly, with rich functions and strong practicability.
