Abstract
The utility model discloses a solar charging leisure packsack which comprises a packsack main body, and a left shoulder belt and a right shoulder belt which are connected with the front side surface of the packsack main body; the leisure packsack further comprises a loudspeaker box, a control circuit board, a solar cell panel and an electrical storage device which are all arranged on the leisure packsack, wherein the electrical storage device is electrically connected with the solar cell panel and the control circuit board; the control circuit board is provided with a USB (Universal Serial Bus) interface and a loudspeaker box interface; and the USB interface is exposed to the outer side surface of the leisure packsack. The leisure packsack can charge a digital device through the USB interface and also can play music externally during the traveling through the loudspeaker box. Through the music appreciation externally, the bad influence on ears caused by wearing a pair of earphones for a long time can be effectively avoided.
Description
Technical field
The utility model relates to a kind of leisure knapsack, is meant a kind of solar energy and can be to the knapsack of digital equipment power supply of absorbing, utilize especially.
Background technology
Nowadays work rhythm fast makes many people be busy with hurrying back and forth, thereby free life is more hankered after outdoor activities as mountain-climbing, travelling etc., running into digital equipments such as mobile phone, MP3 in the travelling way, not have electricity be the part trouble, the one, can not find power supply, the 2nd, charging needs certain time of staying on the road, delays hourage.
In addition, people go out outing except having a breath of fresh air and appreciating the landscape of the Nature, also can wish music appreciating simultaneously, eliminating the intense strain of bringing because of moiling, thereby usually also need to carry the device of broadcast music.At present common have portable CD, a MP3 etc., and the volume of these players is less, carries easily.
But above-mentioned player has following shortcoming: it is bad 1, not have outer function or playback of putting, and the user generally can only pass through the earplug music appreciating separately, and can not be with appreciating with the visitor.2 if with exchange with the visitor, need take off earplug, comparatively inconvenience.3, wearing earplug for a long time can make people's ear not feel well.This shows the limitation that music players such as portable CD, MP3 have it to be difficult to overcome.
Summary of the invention
The utility model provides a kind of leisure knapsack, and its purpose is to overcome the above-mentioned defective that prior art exists.
The technical solution of the utility model is as follows:
A kind of solar recharging leisure knapsack, comprise knapsack main body and the left and right shoulder belt that is connected with knapsack main body leading flank, described leisure knapsack also comprises audio amplifier, control circuit board, solar panel and the electrical storage device that is installed on the leisure knapsack, described electrical storage device is electrically connected on solar panel and control circuit board respectively, described control circuit board is provided with USB interface and speaker interface, and described USB interface exposes to the lateral surface of leisure knapsack.
As improvement of the present utility model, described solar panel is embedded at the lateral surface of left and right shoulder belt respectively.
As another kind of improvement the of the present utility model, described solar panel is embedded at the lateral surface of left shoulder belt or right shoulder belt.
As further improvement of the utility model, be sewed with the audio amplifier bag respectively on the described left and right shoulder belt, described audio amplifier is positioned over respectively in the audio amplifier bag.
Further improve as of the present utility model, in order to reduce the barriering effect of audio amplifier bag to music, described audio amplifier bag is provided with the mesh distributed area.
Further, described electrical storage device is battery or lithium battery.
By above-mentioned to description of the present utility model as can be known, advantage of the present utility model is:
1, solar panel can be with the power storage that transforms in electrical storage device, electrical storage device can be to power supplies such as the mobile phone that is connected with USB interface, MP3 by control circuit board, it can be the audio amplifier power supply by speaker interface also simultaneously, therefore leisure knapsack of the present utility model can charge for digital equipment, can in travelling way, discharge outer sound again for traveller's appreciation, thereby avoid the discomfort that produces owing to the long periods of wear earphone.
2, people only need audio output line with MP3 or CD be connected just with the COBBAIF of audio amplifier in use and can appreciate beautiful music, and its use is comparatively convenient.
Description of drawings
Fig. 1 is the perspective view of embodiment one.
Fig. 2 is the perspective view of embodiment two.
The specific embodiment
The specific embodiment of the present utility model is described with reference to the accompanying drawings.
With reference to Fig. 1, a kind of solar recharging leisure knapsack comprises knapsack main body 1 and the left and right shoulder belt 21,22 that is connected with knapsack main body 1 leading flank.Be equiped with control circuit board (not drawing among the figure) and electrical storage device (not drawing among the figure) in the right shoulder belt 22, electrical storage device is generally lithium battery or battery, described control circuit board is provided with USB interface 3 and speaker interface (not drawing among the figure), and USB interface 3 exposes to the lateral surface of right shoulder belt 22.As can be seen from Figure, be sewed with audio amplifier bag 41,42 respectively on the left and right shoulder belt 21,22, be placed with small-sized audio amplifier 51,52 in the audio amplifier bag 41,42 respectively,, be equipped with mesh distributed area 7 on the described audio amplifier bag 41,42 in order to reduce the barriering effect of 41,42 pairs of music of audio amplifier bag.In addition, the top of left and right shoulder belt 21,22 also respectively is embedded with solar panel 61,62; Connect by lead (not drawing among the figure) between above-mentioned each electric elements, lead is embedded at the leisure inside backpacks.
Continuation is with reference to Fig. 1, electrical storage device is electrically connected on solar panel 61,62 and control circuit board respectively, solar panel 61,62 can be with the power storage that transforms in electrical storage device, electrical storage device can be to power supplies such as the mobile phone that is connected with USB interface 3, MP3 by control circuit board, it can be audio amplifier 51,52 power supplies by speaker interface also simultaneously, therefore leisure knapsack of the present utility model can charge for digital equipment, and sound is appreciated for the traveller outside discharging in the travelling way again.
