[0031] Please refer to Figures 1 to 6 The present application provides a backpack with charging function, which comprises a backpack body 10, a solar assembly 30 and a wire winder 50. The front surface of the backpack body 10 is provided with a clamping shell 20, and the clamping shell 20 and the front surface of the backpack body 10 form a sealed cavity. The solar assembly 30 comprises a battery 32 and a solar panel 31. The battery 32 is accommodated in the cavity, and the solar panel 31 is arranged on the outer surface of the clamping shell 20 and electrically connected with the battery 32. The wire winder 50 is built-in in the cavity and rotatably connected with the inner wall of the clamping shell 20. The wire winder 50 is provided with a charging wire 53 wound therein. One end of the charging wire 53 is connected with the battery 32, and the bottom of the clamping shell 20 is provided with an outlet. The other end of the charging wire 53 extends out of the cavity through the outlet and is connected with an electronic device.

[0032] Exemplarily, the solar panel 31 can convert the absorbed solar energy into electrical energy and store it in the battery 32, which can meet the power supply and also meet the environmental protection requirements. The battery 32 can be charged by the battery 32 or other power supply, which can reduce the limitations of the battery 32 and reduce the situation that the battery 32 cannot be charged due to insufficient power.

[0033] The backpack with charging function based on the technical features above, by setting the clamping shell 20 on the front of the backpack body 10, so that a cavity is formed between the front of the backpack body 10 and the clamping shell 20, and the battery 32 is stored in the cavity, and the solar panel 31 electrically connected with the battery 32 is arranged on the outer surface of the clamping shell 20, so as to convert the solar energy absorbed by the solar panel 31 into electric energy and store it in the battery 32, and then electrically connect one end of the charging line 53 with the battery 32, and the other end of the charging line 53 extends into the cavity and is connected with the electronic device to be charged, so that the electronic device can be charged anytime and anywhere without additional configuration of the power bank and the charging line 53. At the same time, the line winder 50 is arranged in the cavity, so that the charging line 53 pulled out of the cavity can be automatically wound back into the cavity without manual winding, which is simple in structure and convenient in winding.

[0034] In a possible implementation, the line winder 50 includes a housing 51, a rotating disc 55, a coil spring 54, and a locking piece 52. The housing 51 is fixed to the inner wall of the clamping shell 20 and defines an installation cavity with the inner wall of the clamping shell 20. The rotating disc 55 is rotatably arranged in the installation cavity. The coil spring 54 is fixed in the installation cavity, and one end of the coil spring 54 is connected with the rotating disc 55. The locking piece 52 is embedded in the front of the clamping shell 20, and part of the locking piece 52 extends into the installation cavity to lock the rotating disc 55. The charging line 53 is wound on the rotating disc 55, and both ends of the charging line 53 extend out of the opposite ends of the housing 51 and are connected with the battery 32 and the electronic device respectively.

[0035] Exemplarily, the rotating disc 55 is rotatably arranged in the installation cavity defined between the housing 51 and the clamping shell 20. The charging line 53 is wound on the rotating disc 55, and both ends of the charging line 53 extend out of the opposite sides of the housing 51. When charging the electronic device to be charged, one end of the charging line 53 in the cavity is pulled outwards to rotate the rotating disc 55, so that the charging line 53 wound on the rotating disc 55 is lengthened, thereby meeting the demand for different lengths of the charging line 53. After the charging line 53 is lengthened to the required length, the locking piece 52 is used to lock the rotating disc 55, so that the rotating disc 55 does not rotate, thereby ensuring that the charging line 53 maintains a fixed length during charging. After the charging is completed, the locking piece 52 is pressed to release the locking of the rotating disc 55, so that the charging line 53 is automatically wound.

[0036] In a possible implementation, the surface of the housing 51 towards the clamping shell 20 is provided with a placement position 51c, the middle part of the placement position 51c is provided with a rotating shaft extending towards the clamping shell 20, the rotating disc 55 is arranged in the placement position 51c and can rotate around the rotating shaft, the rotating disc 55 is provided with a fixed shaft at the periphery, and the coil spring 54 is wound on the fixed shaft.

[0037] In a possible implementation, the rotating disc 55 is provided with a protrusion 52a on the surface facing the clamping shell 20, the protrusion 52a is provided with a through hole for the rotating shaft to pass through, and the protrusion 52a is provided with a card hole for clamping one end of the coil spring 54. In this way, the rotating disc 55 can be rotatably arranged in the inner part of the shell 51, and one end of the coil spring 54 is clamped into the card hole. When the charging wire 53 is disconnected from the electronic device, the coil spring 54 pulls the rotating disc 55 to rotate in the opposite direction due to its own elastic force, so as to rewind the charging wire 53 pulled out from the rotating disc 55 onto the coil, thereby realizing automatic winding of the charging wire 53.

[0038] In a possible implementation, the shell 51 is provided with a first cavity 51a and a second cavity 51b facing each other and communicating with the placing position 51c, and the two ends of the charging wire 53 respectively extend from the first cavity 51a and the second cavity 51b. In this way, by arranging the first cavity 51a and the second cavity 51b on the shell 51 and communicating with the placing position 51c, the two ends of the charging wire 53 wound on the rotating disc 55 can respectively pass out of the two sides of the shell 51 along the first cavity 51a and the second cavity 51b, which can play a guiding role and avoid the problem that the charging wire 53 is tangled and stuck, resulting in that the charging wire 53 cannot be normally pulled out.

[0039] In a possible implementation, the shell 51 is provided with a first mounting column 56 on the surface facing the clamping shell 20, and the inner wall of the clamping shell 20 is provided with a second mounting column for inserting the first mounting column 56. In this way, the second mounting column is arranged on the surface of the clamping shell 20, and the first mounting column 56 is arranged on the surface of the shell 51 facing the clamping shell 20, so that the shell 51 is fixed on the inner wall of the clamping shell 20 by inserting the first mounting column 56 into the second mounting column. The structure is simple, easy to disassemble and assemble, and convenient for subsequent disassembly of the winding device 50.

[0040] In a possible implementation, at least one shoulder strap 40 is arranged on the back of the backpack body 10, one end of the shoulder strap 40 is connected to the upper part of the back of the backpack body 10, and the other end of the shoulder strap 40 is connected to the lower part of the back of the backpack body 10. For example, in order to make the backpack body 10 more balanced when worn on the back, two shoulder straps 40 are arranged on the back of the backpack body 10, and the two shoulder straps 40 are arranged on the shoulders of the human body to achieve better balance.

[0041] In a possible implementation, the back of the backpack body 10 is provided with a wear-resistant soft pad. When the backpack is worn and walked, the back of the backpack body 10 repeatedly rubs against the back of the human body, which is easy to cause wear on the back of the backpack body.

[0042] It can be understood that the above embodiment only expresses the preferred embodiment of the utility model, the description is more specific and detailed, but it can not be understood as the limitation of the utility model patent scope; it should be pointed out that for ordinary skilled person in the art, the above technical features can be freely combined without departing from the concept of the utility model, and a number of deformations and improvements can be made, which belong to the protection scope of the utility model; therefore, any equivalent transformation and modification within the scope of the utility model patent claim should belong to the scope of the utility model patent claim.
