[0038] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0039] According to some embodiments of this utility model, refer to Figures 1 to 7The detachable seat includes a base 100, a rear seat 200, a spring 110, and a backrest 300. The rear seat 200 is located behind the base 100 and is rotatably connected to the base 100. A positioning block 210 is provided on the front side of the rear seat 200. The two ends of the spring 110 are connected to the base 100 and the rear seat 200, respectively. A first positioning groove 310 is provided on the rear side of the backrest 300 with the groove opening facing downwards. The positioning block 210 can be inserted upwards into the first positioning groove 310 to position and assemble the rear seat 200 and the backrest 300. When the detachable seat is needed, the backrest 300 is brought close to the rear seat 200 from top to bottom, so that the first positioning groove 310 aligns with the positioning block 210. The positioning block 210 is then inserted into the first positioning groove 310, completing the assembly of the backrest 300 and the rear seat 200. The positioning block 210 abuts against the front and rear walls of the first positioning groove 310, thereby restricting the backrest 300 from moving relative to the rear seat 200 in the front-back direction. The upper end of the positioning block 210 abuts against the upper wall of the first positioning groove 310, thereby restricting the backrest 300 from moving further downward. This assembly is simple and convenient for users.

[0040] Understandably, when the detachable seat needs to be transported, the backrest 300 and the rear seat 200 can be disassembled and the backrest 300 can be placed flat on the base 100, which can reduce the space occupied by the detachable seat and improve transportation efficiency.

[0041] It is also understandable that when a person leans back on the backrest 300, the backrest 300 causes the rear seat 200 to rotate backward relative to the base 100, and the spring 110 is deformed under pressure. When the person leaves the backrest 300, under the action of the spring 110, the backrest 300 and the rear seat 200 rotate forward to return to their initial state. Because the installation of the spring 110 is complex, the rear seat 200 and the base 100 are not convenient for users to assemble themselves. This embodiment reduces the difficulty of user assembly while minimizing the volume occupied during transportation, thereby improving transportation efficiency.

[0042] According to some embodiments of this utility model, refer to Figures 3 to 5 The rear wall of the first positioning groove 310 is provided with a notch 320, which extends downward and connects to the lower opening of the first positioning groove 310. The notch 320 facilitates the insertion of the positioning block 210 into the first positioning groove 310, and part of the positioning block 210 is located within the notch 320.

[0043] According to some embodiments of this utility model, refer to Figure 3 and Figure 4The front side of the positioning block 210 is provided with a first elastic block 220, and the front groove wall of the first positioning groove 310 is provided with a first limiting hole 330. When the first elastic block 220 is partially located in the first limiting hole 330, the first elastic block 220 restricts the backrest 300 from moving in the up and down direction. Understandably, during the assembly of the backrest 300 and the rear seat 200, the positioning block 210 is inserted upward into the first positioning groove 310. The groove wall of the first positioning groove 310 presses against the first elastic block 220, causing the first elastic block 220 to move backward. At this time, the first elastic block 220 has a biasing force to return to its initial state. When the first elastic block 220 continues to move upward with the positioning block 210 to align with the first limiting hole 330, the first elastic block 220 moves forward under the action of the biasing force to insert into the first limiting hole 330. With the cooperation of the first elastic block 220 and the first limiting hole 330, the backrest 300 is restricted from moving in the vertical direction relative to the rear seat 200, thereby completing the assembly of the backrest 300 and the rear seat 200.

[0044] Preferred, refer to Figure 3 The front side of the first elastic block 220 includes a vertical surface 231 and an inclined surface 232. The vertical surface 231 is located above the inclined surface 232, and the lower side of the vertical surface 231 is connected to the upper side of the inclined surface 232. The inclined surface 232 is inclined forward from top to bottom. The inclined surface 232 and the lower side of the first elastic block 220 form a tip 240, which can be inserted into the first limiting hole 330. It can be understood that during the process of the first elastic block 220 moving upward with the positioning block 210, the vertical surface 231 is in contact with the front groove wall of the first positioning groove 310. Then, the inclined surface 232 is in contact with the front groove wall of the first positioning groove 310 and guides the first elastic block 220 to move backward. When the tip 240 is aligned with the first limiting hole 330, the tip 240 is inserted into the first limiting hole 330.

[0045] According to some embodiments of this utility model, refer to Figure 3 The front side of the positioning block 210 is provided with a second positioning groove 250. One side of the spring piece 110 is located in the second positioning groove 250 and fits against the groove wall of the second positioning groove 250.
