Description

This invention relates to a seat and a stroller, and more particularly to a seat that is easy to operate and has a simple structure, and a stroller equipped with the same. Strollers are tools used by parents to take their babies or children shopping. Currently, some strollers have height adjustment mechanisms that allow users to adjust the seat height to suit their baby or child, making them more comfortable. However, conventional seat height adjustment mechanisms are not only cumbersome to operate but also complex. Therefore, they are inconvenient to operate and maintain, and increase the manufacturing cost of strollers. Figure 1 is a side view showing a stroller according to one embodiment of the present invention.Figure 2 is a side view of the sheet shown in Figure 1, adjusted to a different height.Figure 3 is a perspective view showing the stroller shown in Figure 2.Figure 4 is an exploded view of the support base and the lock release member.Figure 5 is an exploded view of the support base and unlocking member shown in Figure 4, from a different angle. Referring to Figures 1 to 5, Figure 1 is a side view of a stroller 1 according to one embodiment of the present invention, Figure 2 is a side view of the seat shown in Figure 1 adjusted to a different height, Figure 3 is a perspective view of the stroller 1 shown in Figure 2, Figure 4 is an exploded view of the support base 120 and the lock release member 122, and Figure 5 is an exploded view of the support base 120 and the lock release member 122 shown in Figure 4 from a different angle. As shown in Figures 1 and 2, a stroller 1 according to one embodiment of the present invention comprises a frame 10 and a seat 12. The stroller 1 may be a baby stroller or another type of vehicle. The seat 12 is positioned on the frame 10. The seat 12 of the stroller 1 has a height adjustment mechanism that allows the user to adjust the height of the seat 12 to suit the baby or child, making the baby or child more comfortable. Note that the structure of the stroller 1 and seat 12 in one embodiment is substantially symmetrical, and in the following description, the technical features of the height adjustment mechanism in one embodiment will be explained using the structure of one side. As shown in Figure 3, the frame 10 includes a fixed base 100. As shown in Figures 3 to 5, the seat 12 comprises a support base 120, an unlocking member 122, a locking member 124, a seat body 126, and a plurality of return members 128. Note that the number of return members 128 may be at least one, depending on the actual application. 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. Therefore, 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. 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. 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. 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 lon
