[0055] According to the belt body of the embodiment of the utility model, through the detachable connection between the power module 1 and the flexible belt body, the power module 1 can be removed from the flexible belt body when charging, which is convenient for users to charge. Moreover, when the power module 1 is connected to the flexible belt body, the electrical connection between the power module 1 and the functional module can be realized, which can reduce the installation steps of the power module 1 and make it more convenient for users to use. After the installation is completed, the auxiliary fixing component can further fix the power module 1, which can prevent the power module 1 from shaking or even falling off due to vibration during use, affecting the operation of the belt body, thereby ensuring the user's use experience.

[0056] In some embodiments, the belt body further includes a control module for controlling the functional module;

[0057] The control module includes a control box, in which a control circuit is arranged. The power module 1 is detachably arranged on the outer wall surface of the control box, and the control circuit is powered by the control box.

[0069] Specifically, each belt body can be adapted to two or more power modules 1. When one power module 1 is being charged, another power module 1 can be installed on the flexible belt body without affecting the user's continued use of the belt body.

[0070] In some embodiments, the auxiliary fixing component is provided on the flexible belt body. When the power module 1 is in a state separated from the flexible belt body, the auxiliary fixing component is separated from the power module 1. When the power module 1 is in a state connected to the flexible belt body, the auxiliary fixing component is against the side of the power module 1.

[0071] Specifically, the auxiliary fixing component is arranged on the flexible belt body. When the power module 1 is removed from the flexible belt body, the auxiliary fixing component is separated from the power module 1, and does not affect the disassembly function of the power module 1. When the power module 1 is installed on the flexible belt body, the auxiliary fixing component abuts against the power module 1 to strengthen the fixation of the power module 1, thereby preventing the power module 1 from shaking or loosening and falling due to accidental touch or vibration when the user uses the belt body, thereby affecting the control and power supply effect of the power module 1, affecting the user's normal use of the belt body, and affecting the user's usage experience.

[0072] In some embodiments, the flexible belt is provided with a charging base 2, the charging base 2 is provided with a first contact electrical connection module 4, the power module 1 is provided with a connecting block 3, the connecting block 3 is provided with a second contact electrical connection module 5, the connecting block 3 is detachably connected to the charging base 2, and when the connecting block 3 is connected to the charging base 2, the first contact electrical connection module 4 is in contact with and electrically connected to the second contact electrical connection module 5.

[0073] Specifically, the flexible belt body and the power module 1 are connected and fixed through the charging base 2 and the connecting block 3, and while being physically connected and fixed, the electrical connection can be completed through the mutual cooperation of the first contact electrical connection module 4 and the second contact electrical connection module 5. There is no need to plug and unplug the wiring harness, which can facilitate user disassembly and assembly, thereby improving the user experience.

[0074] In some embodiments, the charging base 2 is provided with a positioning column 6 , and the connecting block 3 has a positioning groove 7 that is adapted in shape to the positioning column 6 and has a corresponding position.

[0075] Specifically, the positioning column 6 and the positioning groove 7 can cooperate with each other to provide positioning for the connecting block 3, thereby preventing the connecting block 3 from tilting when connected to the charging base 2, affecting the fixing strength, and affecting the contact and cooperation between the first contact electrical connection module 4 and the second contact electrical connection module 5.

[0076] In some embodiments, the auxiliary fixing assembly includes a telescopic member, which can gradually stretch or expand until it abuts against the side of the power module 1 during the process of the power module 1 being installed and connected to the flexible belt.

When the power module 1 is installed on the flexible belt body, the telescopic part can stretch or expand and abut against the side of the power module 1. The power module 1 is fixed by the friction force generated by the telescopic part and the side of the power module 1, thereby improving the connection strength between the flexible belt body and the power module 1 and preventing the power module 1 from shaking or falling off.

[0078] In some embodiments, the auxiliary fixing assembly includes: a gas rod 8, a piston 9, a gas cylinder 10 and a gas tube 11;

[0079] One end of the gas rod 8 is connected to the piston 9, the piston 9 is cooperatively connected to the gas cylinder 10, the air pipe 11 connects the gas cylinder 10 and the telescopic part. During the installation and connection of the power module 1 to the flexible belt body, the gas rod 8 drives the piston 9 to compress the gas in the gas cylinder 10, so that the gas enters the telescopic part from the air pipe 11, driving the telescopic part to extend or expand.

[0080] Specifically, the telescopic part is driven by the cooperation of the gas rod 8, the piston 9, the gas cylinder 10 and the air pipe 11. The gas rod 8 drives the movable piston 9 to move in the gas cylinder 10, and discharges the gas in the gas cylinder 10 from the air pipe 11 into the telescopic part, so that the telescopic part expands or stretches, and the power module 1 is fixed. The gas rod 8 moves in the opposite direction, and the air can be extracted from the telescopic part to shrink the telescopic part without affecting the disassembly of the power module 1.

[0081] During the process of installing and connecting the power module 1 to the flexible belt body, the gas rod 8 can be pressed to make the gas rod 8 drive the piston 9 to inflate the telescopic part. That is, during the process of the user installing the power module 1, the telescopic part can automatically expand or extend to fix the power module 1 without the need for additional action, which can be more convenient for users to use. When the user disassembles the power module 1, the telescopic part is in a relaxed state and does not affect the user's disassembly of the power module 1.

[0082] In some embodiments, the gas rod 8 and the gas cylinder 10 form a positioning column 6 , and when the power module 1 is installed and connected to the flexible belt, the positioning groove 7 presses against the gas rod 8 .

[0083] Specifically, the positioning column 6 is a gas rod 8 and a gas cylinder 10.

[0084] In some embodiments, a positioning cap 12 is provided on the top of the gas rod 8 , and the shape of the positioning cap 12 is adapted to the positioning groove 7 .

[0085] Specifically, the positioning cap 12 is adapted to the positioning groove 7 , so that the positioning effect of the positioning groove 7 and the positioning column 6 is more accurate, and the top of the positioning cap 12 can be designed with an outer circle fillet to facilitate the matching of the positioning groove 7 and the positioning cap 12 .

[0086] In some embodiments, the telescopic member is an airbag 13 , and the airbag 13 is arranged around the side of the power module 1 .

[0087] Specifically, the telescopic part can be an airbag 13, which is a strip-shaped annular airbag 13, and is arranged on the charging base 2 around the side of the power module 1. The airbag 13 can be inflated by an air cylinder 10. The inner circle of the inflated airbag 13 abuts against the side of the power module 1, and the power module 1 can be fixed by friction.
