A handle is installed on the headstock, and a front wheel is installed on the front fork. A seat and a footrest are installed in the middle of the frame, and a rear wheel is installed at the rear of the frame. It is characterized in that: the bottom end of the headstock is coaxially fixed with the top end of the front fork and is inserted into the frame. The headstock and the front fork are both rotatably connected to the frame around the vertical direction, and the rotation angle is 360°.

[0004] Most of the existing performance bicycles will directly remove the fender above the rear wheel, and some will retain the fender. However, the existing fenders are mostly made of hard materials and can only play the role of mudguard. The rear seat of the performance bicycle is a low-back seat cushion. When the rider makes some actions with the center of gravity tilted backward, especially when beginners are riding, there is a possibility that the buttocks will come into direct contact with the rear wheel, posing a potential risk of injury. Therefore, it is urgent to propose a corresponding extended performance seat to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an extended performance seat in order to solve the above problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An extended performance seat includes a seat cushion and a bottom rod fixedly connected. An outer frame is fixedly connected to the outer wall of the bottom rod through a fastening sleeve. A clamping sleeve is arranged outside the bottom rod. A rear extension flap is detachably connected to the inner wall of the clamping sleeve, and the rear extension flap is made of a highly elastic material. An elevating component for adjusting the vertical position of the rear extension flap is arranged between the clamping sleeve and the outer frame.

[0008] Preferably, the elevating component includes a sliding strip and a fixed sleeve that are slidably matched. The sliding strip and the fixed sleeve are respectively fixedly connected to the outer frame and the clamping sleeve, and a positioning part for positioning the sliding strip is arranged on the outer wall of the fixed sleeve.

[0009] Preferably, the positioning part includes a positioning rod which passes through the fixed sleeve through a perforation. The positioning rod is fixedly connected to the sliding strip through a screw hole. A plurality of groups of screw holes are provided, and the plurality of groups of screw holes are linearly distributed along the extending direction of the sliding strip.

[0010] Preferably, the fastening sleeve includes two half sleeves that are rotationally engaged with each other. Lugs are fixedly connected to the outer surfaces of the two half sleeves, and the two lugs are fixedly connected through a fastening rod.

[0011] Preferably, the outer frame and the sliding strip, and the fixed sleeve and the clamping sleeve are integrally formed, and the outer frame is fixedly connected to the outer surface of the half sleeve through a fixing rod.

[0012] Preferably, the end of the rear extension flap is inserted into the inner wall of the clamping sleeve, and the rear extension flap is fixedly connected to the clamping sleeve through a locking rod.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] 1. In this application, the effective riding position at the rear part of the seat cushion is extended by 50%, and the riding length of the seat cushion is lengthened. When the rider performs a performance action that requires the center of gravity to lean backward, after the rider's buttocks contact the rear extension flap, the rear extension flap will be deflected, so that it neither affects the display of the action nor allows the rider's buttocks to directly contact the follow-up. Moreover, the rear extension flap is first inserted into the inside of the clamping sleeve and then positioned through the locking rod, ensuring the stable position of the rear extension flap while not affecting the deflection amplitude of the rear extension flap. And when the rear extension flap is damaged later, only the rear extension flap needs to be replaced, without synchronously replacing the support components such as the fastening sleeve.

[0015] 2. In this application, rotate the positioning rod to disengage it from the screw hole in the initial position, move the fixed sleeve upward as a whole so that the screw hole in the appropriate position corresponds to the positioning rod, and use the locking rod to combine with the screw hole in this position to realize the repositioning of the fixed sleeve and the sliding strip, so that the position of the rear extension flap can be synchronously adjusted following the adjustment of the seat cushion height, ensuring that the rear extension flap can always maintain a constant distance from the rear wheel.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0024] An extended performance seat includes a seat cushion 1 and a bottom rod 2 fixedly connected. The outer wall of the bottom rod 2 is fixedly connected with an outer frame 4 through a fastening sleeve 3. A clamping sleeve 7 is arranged outside the bottom rod 2. The inner wall of the clamping sleeve 7 is detachably connected with a rear extension flap 9, and the rear extension flap 9 is made of a high-elastic material. An elevating component for adjusting the vertical position of the rear extension flap 9 is arranged between the clamping sleeve 7 and the outer frame 4;

[0025] The effective riding position at the rear of the seat cushion 1 is extended by 50%, and the riding length of the seat cushion 1 is elongated. When the rider performs a performance action that requires the center of gravity to lean backward, after the rider's buttocks touch the rear extension flap 9, the rear extension flap 9 will be deflected, so that it neither affects the display of the action nor allows the rider's buttocks to directly contact the rear wheel. Moreover, the rear extension flap 9 is first inserted into the clamping sleeve 7 and then positioned by the locking rod 8, which ensures the stable position of the rear extension flap 9 while not affecting the deflection amplitude of the rear extension flap 9. And after the rear extension flap 9 is damaged later, only the rear extension flap 9 needs to be replaced, without synchronously replacing the support components such as the fastening sleeve 3.

[0026] Specifically, as Figure 2 and Figure 4As shown in the figure, the lifting assembly includes a slide bar 5 and a fixed sleeve 6 that are slidably mated. The slide bar 5 and the fixed sleeve 6 are respectively fixedly connected to the outer frame 4 and the clamping sleeve 7. And a positioning portion for positioning the slide bar 5 is provided on the outer surface wall of the fixed sleeve 6. The positioning portion includes a positioning rod 10. The positioning rod 10 passes through the fixed sleeve 6 through a perforation. The positioning rod 10 is fixedly connected to the slide bar 5 through a screw hole 13. There are multiple groups of screw holes 13, and the multiple groups of screw holes 13 are linearly distributed along the extending direction of the slide bar 5. Rotate the positioning rod 10 to disengage it from the screw hole 13 in the initial position. Move the fixed sleeve 6 upward as a whole so that the screw hole 13 in a suitable position corresponds to the positioning rod 10. By combining the positioning rod 10 with the screw hole 13 in this position, the re-positioning of the fixed sleeve 6 and the slide bar 5 is achieved. In this way, the position of the rear extension flap 9 can be synchronously adjusted following the adjustment of the height of the seat cushion 1, so that the rear extension flap 9 can always maintain a constant distance from the rear wheel.

[0027] Specifically, as Figure 2 shown in Figure 3 the figure, the fastening sleeve 3 includes two half sleeves that are rotatably mated. Lugs 11 are fixedly connected to the outer surface walls of the two half sleeves, and the two lugs 11 are fixedly connected by a fastening rod, so as to ensure the convenience of disassembling the fastening sleeve 3 and the bottom rod 2. The outer frame 4 and the slide bar 5, as well as the fixed sleeve 6 and the clamping sleeve 7, are integrally formed, so as to ensure the structural strength between the components. And the outer frame 4 is fixedly connected to the outer surface wall of the half sleeve through a fixing rod 12, so as to ensure the convenience of disassembling the outer frame 4 and the fastening sleeve 3. The end of the rear extension flap 9 is inserted into the inner surface wall of the clamping sleeve 7, and the rear extension flap 9 is fixedly connected to the clamping sleeve 7 through a locking rod 8. The rear extension flap 9 is first inserted into the clamping sleeve 7 and then positioned through the locking rod 8. While ensuring the stable position of the rear extension flap 9, it does not affect the deflection amplitude of the rear extension flap 9. And after the rear extension flap 9 is damaged subsequently, only the rear extension flap 9 needs to be replaced, without synchronously replacing the support components such as the fastening sleeve 3.

[0028] Working principle: The effective riding position at the rear of the saddle 1 is extended by 50%, and the riding length of the saddle 1 is elongated. When the rider performs a performance action that requires the center of gravity to lean backward, after the rider's buttocks come into contact with the rear extension flap 9, the rear extension flap 9 will be deflected. In this way, it not only does not affect the display of the action, but also can prevent the rider's buttocks from directly contacting the rear wheel. Moreover, the rear extension flap 9 is first inserted into the inner part of the ferrule 7 and then positioned by the locking rod 8, which ensures the stable position of the rear extension flap 9 while not affecting the deflection amplitude of the rear extension flap 9. And after the rear extension flap 9 is damaged subsequently, only the rear extension flap 9 needs to be replaced, without the need to synchronously replace the support components such as the fastening sleeve 3. Rotate the positioning rod 10 to disengage it from the screw hole 13 in the initial position, and move the fixing sleeve 6 upward as a whole so that the screw hole 13 at a suitable position corresponds to the positioning rod 10. Through the positioning rod 10 combined with the screw hole 13 at this position, the repositioning of the fixing sleeve 6 and the slide bar 5 is realized, so that the position of the rear extension flap 9 can be synchronously adjusted following the adjustment of the height of the saddle 1, ensuring that the rear extension flap 9 can always maintain a constant distance from the rear wheel.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather should be accorded the widest scope consistent with the principles and novel features disclosed herein.
