Description

Technical Field

[0001] This invention relates to the field of schoolbag technology, and more particularly to a solar-powered, audio-visual learning schoolbag. Background Technology

[0002] People still largely maintain dialect-based communication habits in their daily lives, resulting in a lack of language context for primary school students' extracurricular language learning. With the development of technology, the use of televisions, smartphones, and other internet-connected devices also has a significant advantage in extracurricular language learning for primary and secondary school students. However, the network environment is complex and can easily lead students to be misled by unfavorable factors when using such devices. These devices all require direct connection to a power source or pre-stored power, which can limit their long-term use due to insufficient power. In addition, tablet computers are relatively expensive. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the ease with which users can be misled by adverse factors when learning languages ​​using tablets or mobile phones, and the limitation of insufficient power preventing the devices from being used for extended periods. This invention proposes a solar-powered rechargeable listening and reading learning backpack.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: Design a solar-powered, audio-visual learning backpack, including a backpack body, a cover at the top of the backpack body, a shoulder strap on one side of the backpack body, a fixing frame on the side of the backpack body away from the shoulder strap, a solar charging panel for converting solar energy into electrical energy on the fixing frame, a battery block for storing electrical energy on the backpack body above the fixing frame, a micro controller on the backpack body above the fixing frame, and a player for playing knowledge content on the backpack body.

[0005] Preferably, the shoulder strap is provided with a plurality of heat dissipation holes for heat dissipation.

[0006] Preferably, an elastic pad is provided on one side of the backpack body. The elastic pad is a sponge pad, and the elastic pad is located on the same side as the shoulder strap.

[0007] Preferably, the backpack body has mesh pockets on both sides for holding items, and the mesh pockets are made of elastic fibers.

[0008] Preferably, two parallel rainproof cloths are fixedly connected to one side of the backpack body, and the solar charging panel is located between the two rainproof cloths. Each rainproof cloth has a positive Velcro fastener on one side and a negative Velcro fastener on the other side.

[0009] Preferably, a baffle is fixedly connected to one side of the backpack body, and the baffle is located above the rainproof cloth.

[0010] Preferably, the backpack body has a hard board inside, and the hard board and the fixing frame are located on the same side.

[0011] Preferably, the rigid plate is a polyethylene plate.

[0012] The solar-powered audio-visual learning backpack proposed in this invention has the following advantages: 1. Solar energy is converted into electrical energy through a solar charging panel. The converted electrical energy is regulated by a voltage converter and then transmitted to the battery pack for storage. After the micro controller is turned on, the audio files of Chinese and English knowledge stored on the built-in knowledge storage card are played through the player. It is not affected by adverse factors and is not limited by power. The cost of the backpack is low.

[0013] 2. The upper part of the solar charging panel, battery block and microcontroller is shielded by a baffle. The baffle and two rainproof cloths protect the solar charging panel, battery block and microcontroller and prevent rainwater from falling on the solar charging panel, battery block and microcontroller.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] Example 1 Reference Figure 1-3A solar-powered audio-visual learning backpack includes a backpack body 1, a cover 4 at the top of the backpack body 1, a shoulder strap 2 on one side of the backpack body 1 with several ventilation holes 3 for heat dissipation, a sponge elastic pad 5 on one side of the backpack body 1, the sponge elastic pad 5 being on the same side as the shoulder strap 2, mesh pockets 6 on both sides of the backpack body 1 for holding items, the mesh pockets 6 being elastic fiber pockets, a fixing frame 7 on the side of the backpack body 1 away from the shoulder strap 2, a solar charging panel 8 for converting solar energy into electrical energy on the fixing frame 7, a battery block 9 for storing electrical energy on the backpack body 1 above the fixing frame 7, a micro controller 10 on the backpack body 1 above the fixing frame 7, the micro controller 10 having an on / off switch and a toggle button, a player 11 for playing knowledge on the backpack body 1, the battery block 9 being connected to the micro controller 10 and the player 11 via wires, and a polyethylene hard board 16 inside the backpack body 1, the hard board 16 being on the same side as the fixing frame 7.

[0018] Work process: When students carry their backpacks on the shoulder straps 2, the ventilation holes 3 promote air circulation, dissipate heat and moisture from the shoulders in a timely manner, and improve wearing comfort. The sponge elastic pad 5 fits against the student's back, effectively cushioning the pressure of the backpack's weight on the spine. On the way to and from school with a schoolbag on its back, sunlight shines on the solar charging panel 8, which converts solar energy into electrical energy. The converted electrical energy is regulated by a voltage converter and then transmitted to the battery pack 9 for storage. When the micro controller 10 is turned on, it plays Chinese and English knowledge audio files stored on the built-in knowledge storage card through the player 11. The power switch and the switching button can control the language audio files played by the micro controller 10, and can switch between different modes such as listening and reading aloud. It is not affected by adverse factors and is not limited by power. The schoolbag has a low cost.

[0019] Example 2 Reference Figure 3-4 As another preferred embodiment of the present invention, the difference from embodiment 1 is that two parallel rainproof cloths 12 are fixedly connected to one side of the backpack body 1, the solar charging panel 8 is located between the two rainproof cloths 12, each rainproof cloth 12 has a positive Velcro 13 on one side and a negative Velcro 14 on the other side, and a baffle 15 is fixedly connected to one side of the backpack body 1, the baffle 15 is located above the rainproof cloths 12. In rainy weather, the positive Velcro 13 on one rainproof cloth 12 is attached to the negative Velcro 14 on another rainproof cloth 12. After the two rainproof cloths 12 are attached, they are unfolded to cover the solar charging panel 8, battery block 9, and microcontroller 10. The baffle 15 covers the upper part of the solar charging panel 8, battery block 9, and microcontroller 10. The baffle 15 and the two rainproof cloths 12 protect the solar charging panel 8, battery block 9, and microcontroller 10 from rain. When the weather is sunny, the two rainproof cloths 12 are rolled up, and the negative Velcro 14 on the rainproof cloth 12 is attached to its own positive Velcro 13. Rolling up the rainproof cloth 12 will not cover the solar charging panel 8.

[0020] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
