[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 5 As shown, a detachable load-carrying device for an electric bicycle includes a main body 1 and a mounting assembly 2; the mounting assembly 2 is mounted on a mounting plate 21, a fixing seat 22 is fixedly mounted on the top of the mounting plate 21, a bevel gear 23 is movably mounted on the top of the fixing seat 22, a rotating handle 24 is fixedly mounted on one side of the bevel gear 23, a gear plate 25 is transmission-connected to the top side of the rotating handle 24, and the gear plate 25 is movably mounted on the fixing seat 22 around its periphery;

[0024] During operation, a person rotates the handle 24 to transmit the rotational power of the bevel gear 23 to the toothed disc 25 through the cooperation between the bevel gear 23 and the toothed disc 25 , so that the toothed disc 25 rotates in the inner cavity of the mounting plate 21 .

[0025] Furthermore, the main body 1 is equipped with a carrying box 11, a connecting plate 12 is fixedly installed at the bottom of the carrying box 11, a connecting groove 13 is opened at the bottom of the connecting plate 12, and a plurality of racks 26 are movably installed through the connecting groove 13;

[0026] During operation, the connecting plate 12 opens the connecting groove 13 , and when the rack 26 moves, the connecting groove 13 completes the clamping connection with the connecting plate 12 , thereby achieving the fixation of the carrying box 11 .

[0027] Furthermore, a threaded ring is formed on the top of the toothed disc 25, and a plurality of racks 26 are threadedly engaged with the threaded ring. A connecting seat 27 is movably mounted on the top of the toothed disc 25, and a mounting plate 21 is fixedly mounted on the bottom of the connecting seat 27.

[0028] During operation, the mounting plate 21 is connected to the connecting seat 27 to provide sufficient sealing inside and protect the internal components accordingly. When the toothed disc 25 rotates, the threaded ring drives the rack 26, causing the rack 26 to move relative to the toothed disc 25.

[0029] Furthermore, the connecting seat 27 is provided with a plurality of limiting grooves, and racks 26 are movably mounted through the limiting grooves.

[0030] During operation, when the toothed disc 25 transmits the rack 26 with the threaded ring, the connecting seat 27 opens the limiting groove, so that the rack 26 is limited in its movement, thereby converting the linear movement of the toothed disc 25 into the linear movement of the rack 26 in the limiting groove, which is conducive to the active clamping and fixing of the rack 26 in the inner cavity of the connecting groove 13.

[0031] Furthermore, a fixing frame 28 is fixedly mounted on the bottom of the mounting plate 21, a handle 29 is hinged to one side of the fixing frame 28, and a linkage rod 31 is hinged to one side of the handle 29;

[0032] During operation, the fixing frame 28 is fixed by the mounting plate 21 , and when a person moves the handle 29 , the handle 29 moves in a circle with the hinge of the fixing frame 28 as an axis.

[0033] Furthermore, the other end of the linkage rod 31 is hinged with a movable arm 32, which is hinged to one side of the fixing frame 28, and one end of the movable arm 32 is movable with a limit head 33;

[0034] During operation, when the handle 29 moves, the linkage rod 31 links the movable arm 32, so that the movable arm 32 moves in a circle with the hinge of the fixed frame 28 as the axis, so that the limit head 33 installed at the other end of the movable arm 32 moves up and down accordingly, so that the limit head 33 contacts the bottom of the carrying box 11, generates an interaction force on the bottom of the carrying box 11, and limits the bottom of the carrying box 11 to prevent movement.

[0035] Working principle: During installation, the connecting groove 13 opened on the connecting plate 12 is docked with the top of the connecting seat 27. At this time, the personnel rotates the turning handle 24, so that the turning handle 24 drives the toothed disc 25 to rotate counterclockwise through the bevel gear 23 fixed at the bottom. At the same time, the threaded ring on the other side of the toothed disc 25 and the latching teeth opened on the rack 26 are transmitted in a threaded manner. The rack 26 is limited by the sliding groove opened on the connecting seat 27 when it is active. Therefore, when the toothed disc 25 rotates, the rotating motion of the toothed disc 25 is converted into linear motion of the rack 26 inside the sliding groove through cooperation. The rack 26 expands outward and completes the engagement and limitation with the connecting groove 13 opened on the connecting plate 12 to achieve overall fixation. Similarly, when disassembly is required, the rack 26 is retracted in the connecting seat 27 to cancel the mutual engagement, so that the entirety can be quickly disassembled without being engaged and limited.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
