The support base 120 is movably inserted into the fixed base 100 of the frame 10, and the seat body 126 is positioned on the support base 120. Thus, the support base 120 can be moved relative to the fixed base 100 of the frame 10 to adjust the height of the seat body 126.

[0011] As shown in Figures 1 to 3, the seat body 126 may include a backrest 1260, a calf rest 1262, a handrail 1264, and a canopy 1266. The backrest 1260 and handrail 1264 are pivotally connected to a pivot 1202 of a support base 120, the calf rest 1262 is pivotally connected to the lower end of the backrest 1260, and the canopy 1266 is rotatably connected to the central portion of the backrest 1260, with the pivot 1202 positioned between the canopy 1266 and the calf rest 1262. Thus, the calf rest 1262, handrail 1264, and canopy 1266 can rotate relative to the backrest 1260 to fold or unfold. In practical applications, the backrest 1260 and calf rest 1262 may be covered with fabric to form a seat area for seating. In another embodiment, the seat body 126 may further comprise other support or reinforcement structures (e.g., seat plates) depending on the actual application. It should be noted that the present invention is not limited to the illustrated embodiments, as the structure of the seat body 126 can be determined according to the actual application.

[0012] As shown in Figure 4, the front casing 120a of the support base 120 has a plurality of through holes 1200, which are spaced apart along the longitudinal direction of the support base 120. Note that the number of through holes 1200 may be at least one, depending on the actual application. The unlocking member 122 is movably positioned on the support base 120. In this embodiment, the unlocking member 122 is movably positioned between the front casing 120a (as shown in Figure 4) and the rear casing 120b (as shown in Figure 5) of the support base 120.

[0013] As shown in Figures 4 and 5, the unlocking member 122 has an operating section 1220, a longitudinal groove 1222, a plurality of first drive sections 1224, and a plurality of restraining recesses 1226, forming a dwelling space 1230 between the unlocking member 122 and the rear casing 120b of the support base. Note that the number of first drive sections 1224 and restraining recesses 1226 may be at least one, depending on the actual application. The operating section 1220 is located at the end of the longitudinal groove 1222 and extends from the support base 120 along the longitudinal direction of the longitudinal groove 1222. The first drive sections 1224 are located within the dwelling space 1230 and are positioned along the longitudinal direction of the longitudinal groove 1222 on at least one side of the longitudinal groove 1222. In some embodiments, the first drive sections 1224 are positioned on both sides of the longitudinal groove 1222. Furthermore, the restraining recess 1226 is located on the side of the unlocking member 122 facing the front casing 120a of the support base 120 and is positioned on at least one side of the longitudinal groove 1222. The locking member 124 is movably positioned on the unlocking member 122. In this embodiment, the locking member 124 is movably positioned within the housing space 1230 of the unlocking member 122, and the direction of movement of the unlocking member 122 is substantially perpendicular to the direction of movement of the locking member 124, but the present invention is not limited thereto.

[0014] As shown in Figures 4 and 5, the locking member 124 has a plurality of locking parts 1240 and a plurality of second drive parts 1242, the second drive parts 1242 being positioned on the sides of the locking parts 1240. The locking parts 1240 and the second drive parts 1242 are spaced apart along the longitudinal direction of the locking member 124 and protrude from the longitudinal groove 1222. It should be noted that the number of locking parts 1240 and second drive parts 1242 may be at least one, depending on the actual application. As shown in Figure 5, the return members 128 are positioned within the housing space 1230, with the opposite ends of each return member 128 in contact with the locking member 124 and the support base 120. In some embodiments, the position of the return members 128 corresponds to the position of the locking parts 1240 (as shown in Figure 4). The return members 128 may, but are not limited to, springs.

[0015] As shown in Figures 3 and 4, after assembling the support base 120, the unlocking member 122, and the locking member 124, the operating portion 1220 of the unlocking member 122 is exposed from the support base 120, the locking portion 1240 of the locking member 124 is positioned in the through hole 1200 of the support base 120, and the second drive portion 1242 of the locking member 124 is restrained in the restraining recess 1226 of the unlocking member 122. At this time, the locking portion 1240 protrudes from the surface of the support base 120 through the through hole 1200. Furthermore, as shown in Figure 5, the second drive portion 1242 of the locking member 124 abuts against the first drive portion 1224 of the unlocking member 122. In this embodiment, the first drive portion 1224 and the second drive portion 1242 have inclined surfaces that abut each other.

[0016] As shown in Figure 5, the pivot 1202 comprises a first pivot 1202a and a second pivot 1202b. The first pivot 1202a is pivotably connected to the backrest 1260, and the second pivot 1202b is pivotably connected to the handrail 1264. The unlocking member 122 further has a slot 1228, and the second pivot 1202b has an insertion portion 1268. The insertion portion 1268 passes through the slot 1228 of the unlocking member 122, and the first pivot 1202a is pivotably connected to the insertion portion 1268 such that the first pivot 1202a and the second pivot portion 1202b rotate relative to each other. When the unlocking member 122 moves up and down relative to the support base 120, the slot 1228 functions as an avoidance space for the insertion portion 1268, preventing the unlocking member 122 from interfering with the insertion portion 1268.

[0017] As shown in Figure 3, the fixed base 100 of the frame 10 has an engagement hole 1000. The seat 12 is fixed to the frame 10 when one of the locking portions 1240 of the locking member 124 engages with the engagement hole 1000. At this time, the seat 12 may be kept at a constant height. If the user wants to adjust the height of the seat 12, the user can press the operating portion 1220 of the unlocking member 122. As shown in Figures 3 to 5, when the operating portion 1220 of the unlocking member 122 is pressed in the first direction A1, the unlocking member 122 is forced to move in the first direction A1, and as a result, the locking member 124 is forced to move in the first direction A1. When the locking member 124 is pushed in the first direction A1, the locking portion 1240 retracts into the support base 120 in a second direction A2 different from the first direction A1.

[0018] To further explain, when the unlocking member 122 is pushed and moves in the first direction A1, the first drive unit 1224 of the unlocking member 122 pushes the second drive unit 1242 of the locking member 124, driving the locking member 124 to move in the second direction A2. At this time, the locking member 124 is forced to move along the first drive unit 1224 via the second drive unit 1242 and retracts into the support base 120, as a result, one of the locking parts 1240 disengages from the engagement hole 1000 of the fixed base 100. At this time, the user can move the seat 12 up and down to adjust the height of the seat 12. When the operating unit 1220 of the unlocking member 122 is pushed in the first direction A1, the locking member 124 moves in the second direction A2 and compresses the return member 128. Therefore, after adjusting the height of the seat 12, the user simply releases the unlocking member 124, and the return member 128 pushes the locking member 124 in a third direction A3, causing one of the locking portions 1240 of the locking member 124 to re-engage with the engagement hole 1000 of the fixed base 100 of the frame 10. When the return member 128 pushes the locking member 124 in a third direction A3, the second drive portion 1242 of the locking member 124 pushes the first drive portion 1224 of the unlocking member 122, driving the unlocking member 122 to move in a fourth direction so that the unlocking member 122 returns.

[0019] Furthermore, the user can also remove the seat 12 from the frame 10 by pressing the operating part 1220 of the unlocking member 122 to disengage one of the locking parts 1240 from the engagement hole 1000 of the fixed base 100. In other words, the user can adjust the height of the seat 12 or remove the seat 12 from the frame 10 simply by pressing the operating part 1220 of the unlocking member 122. This operation is extremely convenient.

[0020] In this embodiment, the number of through holes 1200, first drive units 1224, restraint recesses 1226, locking units 1240, second drive units 1242, and return members 128 are each set to three, allowing the height of the sheet 12 to be adjusted in three stages. Thus, the present invention allows for increasing or decreasing the number of stages for adjusting the height of the sheet 12 by increasing or decreasing the number of through holes 1200, first drive units 1224, restraint recesses 1226, locking units 1240, and second drive units 1226, but the present invention is not limited to the illustrated embodiment.

[0021] As described above, by simply pressing the operating part of the unlocking member, the locking portion of the locking member is retracted into the support base and disengaged from the engagement hole in the frame's fixed base. At this time, the user can adjust the seat height by moving the seat up and down. After adjusting the seat height, the user simply releases the unlocking member, and the locking portion of the locking member re-engages with the engagement hole in the frame's fixed base. The present invention allows a seat height adjustment mechanism to be formed by the support base, unlocking member, and locking member, which is not only simple in structure but also convenient to operate, thereby further reducing the manufacturing costs of the seat and stroller. Furthermore, in some embodiments, the support base may have one single through hole, and the locking member may have one single locking portion. In this case, according to the present invention, the cooperation of one through hole and one locking portion allows the user to easily remove the seat.
