Description

Technical Field

[0001] The utility model relates to the technical field of baby carriages, in particular to a baby carriage base. Background Art

[0002] A baby carriage refers to a stroller or a child cart, which is a device used to propel infants or young children when traveling. A baby carriage usually consists of one or more seats, a base, and multiple running wheels, and is sometimes also equipped with a recliner or sleeping basket to accommodate infants and young children of different ages.

[0003] At present, the existing baby stroller bases on the market do not have a shock-absorbing function. When a child shakes on it, the stroller body will swing up and down or horizontally at the same time, which will affect the stability of the baby stroller structure. Therefore, it is necessary to design a baby stroller base. Utility Model Content

[0007] Preferably, the shock absorbing mechanism comprises a suspension rod, a connecting rod 1 and a connecting rod 2, wherein the suspension rod is fixedly mounted on both sides of the inner top of the upper base, and a pair of connecting rods 1 and 2 are movably mounted at both ends of the two suspension rods, and the other ends of the connecting rods 1 and 2 are cross-arranged;

[0008] Preferably, sliding grooves are symmetrically arranged on both sides of the top of the lower base, and the bottom ends of the connecting rod 1 and the connecting rod 2 are slidably connected to the sliding grooves;

[0009] Preferably, the shock absorbing mechanism further comprises a strip groove and a spring damper, wherein the strip groove is opened on both sides of the inner wall of the sliding groove, the spring damper is fixedly installed at both ends of the sliding groove, and rollers slidably connected to the strip groove are arranged on both sides of the ends of the connecting rod 1 and the connecting rod 2 away from the suspension rod, and a rubber block is arranged on the end of the spring damper close to the roller;

[0010] Preferably, the guide mechanism comprises side blocks, the side blocks are fixedly mounted on the inner walls of both sides of the upper base, and side grooves slidably connected to the side blocks are formed on both sides of the lower base;

[0011] Preferably, the guide mechanism further comprises guide grooves, which are arranged on two sides of the upper base away from the side blocks, and guide blocks slidably connected to the guide grooves are arranged on top of both sides of the lower base.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. This baby carriage base is used in conjunction with a lower base, an upper base, a connecting rod 1, a connecting rod 2, a roller and a spring damper. During daily use, the vibration generated by the vehicle body is transmitted to the upper base, and the upper base drives the connecting rod 1 and the connecting rod 2 on both sides to cross and press down. During the downward pressing process, the connecting rod 1 and the connecting rod 2 drive the roller to slide in the strip groove, and the vibration is reduced by the spring damper, which can achieve the purpose of shock absorption, making the base more stable and having a longer service life.

[0014] 2. A baby carriage base, which is used in conjunction with side blocks, side grooves, guide grooves, guide blocks, a lower base and an upper base. When the upper base is pressed down along the upper end of the lower base, the side blocks on both sides of the inner wall of the upper base will slide up and down in the side grooves at the corresponding positions on both sides of the lower base, which can serve the purpose of guidance. When the upper base is pressed down, the guide blocks on the other two sides of the lower base will slide up and down in the guide grooves on both sides of the inner wall of the upper base. Since the guide grooves are opened inwardly, the guide blocks can not only guide, but also serve the purpose of limiting, thereby preventing the upper base from falling off from the upper end of the lower base.

[0023] A baby carriage base, comprising a lower base 1, an upper base 2 is movably mounted on the top of the lower base 1, a shock absorbing mechanism is arranged between the upper base 2 and the interior of the lower base 1, the shock absorbing mechanism comprises a suspension rod 3, a connecting rod 1 4 and a connecting rod 2 5, the suspension rod 3 is fixedly mounted on both sides of the inner top of the upper base 2, a pair of connecting rods 1 4 and 2 5 are movably mounted at both ends of the two suspension rods 3, the other ends of the connecting rods 1 4 and 2 5 are cross-arranged, sliding grooves 6 are symmetrically arranged on both sides of the top of the lower base 1, the bottom ends of the connecting rods 1 4 and 2 5 are slidably connected to the sliding grooves 6, the shock absorbing mechanism also comprises a strip groove 7 and a spring damper 8, the strip groove 7 is opened on both sides of the inner wall of the sliding groove 6, the spring damper 8 is fixedly mounted on both ends of the inner part of the sliding groove 6, and rollers 9 slidably connected to the strip groove 7 are arranged on both sides of the ends of the connecting rods 1 4 and 2 5 away from the suspension rod 3;

[0024] In this embodiment, the upper base 2 of the device is used to install the body of the baby carriage with a seat, and the lower base 1 is used to install the wheels. During daily use, the vibration generated by the body is transmitted to the upper base 2, and the upper base 2 drives the connecting rods 1 4 and 2 5 on both sides to cross and press down. During the pressing process, the connecting rods 1 4 and 2 5 drive the rollers 9 to slide in the strip grooves 7, and the vibrations are reduced by the spring dampers 8, which can achieve the purpose of shock absorption, making the base more stable and having a longer service life.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a guide mechanism is provided between both sides of the lower base 1 and the upper base 2, and the guide mechanism includes side blocks 11, which are fixedly mounted on the inner walls of both sides of the upper base 2, and side grooves 12 slidably connected to the side blocks 11 are provided on both sides of the lower base 1; the guide mechanism also includes guide grooves 13, which are provided on both sides of the upper base 2 away from the side blocks 11, and guide blocks 14 slidably connected to the guide grooves 13 are provided on the tops of both sides of the lower base 1;

[0026] In this embodiment, when the upper base 2 is pressed down along the upper end of the lower base 1, the side blocks 11 on both sides of the inner wall of the upper base 2 will slide up and down along the side grooves 12 at the corresponding positions on both sides of the lower base 1, which can serve the purpose of guidance. At the same time as the upper base 2 is pressed down, the guide blocks 14 on the other two sides of the lower base 1 will slide up and down along the guide grooves 13 on both sides of the inner wall of the upper base 2. Since the guide grooves 13 are opened inwardly, the guide blocks 14 can not only guide, but also serve the purpose of limiting, thereby preventing the upper base 2 from falling off from the upper end of the lower base 1.
