technical field

The invention relates to the technical field of children's products, in particular to a baby carriage.

Background technique

A children's car is a kind of children's entertainment toy. At present, some children's vehicles on the market are not provided with a canopy. When this type of children's vehicle is used outdoors, it cannot achieve sunshade or rain protection, thereby affecting the comfort of the children's vehicle when it is used. Some children's vehicles are provided with a canopy. For example, a children's electric vehicle with an awning is disclosed in patent CN2016202713239, but the awning on the children's electric vehicle is detachably connected to the car body. The awning is connected on the vehicle body, and when the awning is not needed, the awning is disassembled from the vehicle body, which is inconvenient to operate. Moreover, after the awning is disassembled from the car body in the children's electric vehicle, the awning is separated from the car body, which is inconvenient for the awning to be used at any time.

Detailed ways

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

Example 1

As shown in FIGS. 1 to 12 , the children's carriage of the present invention includes a car body 1 and a canopy assembly 2 movably arranged on the car body 1 .

A seat portion 3 is arranged inside the vehicle body 1 , and doors 6 may be arranged on the left and right sides of the vehicle body 1 . The canopy assembly 2 has a use state and a folded state. When the canopy assembly 2 is in use, the canopy assembly 2 stands above the seat portion 3 to shield children sitting in the seat portion 3 from the sun or rain, as shown in FIGS. 1-3 . When the canopy assembly 2 is in the folded state, the canopy assembly 2 deviates from the top of the seat portion 3 and moves closer to the vehicle body 1, as shown in FIGS. 9-11 .

In this embodiment, when the canopy assembly 2 is in the retracted state, the canopy assembly 2 is accommodated at the upper rear of the vehicle body 1 and forms the rear engine cover of the vehicle body 1 , as shown in FIGS. 9-11 .

The children's vehicle also includes a link mechanism, the link mechanism is arranged between the car body 1 and the canopy assembly 2, the link mechanism is used to support the canopy assembly 2, and by moving the link mechanism relative to the car body 1, the canopy assembly 2 can Toggles between the active state and the collapsed state.

The link mechanism includes a first link 41 and a second link 42 . One end of the first link 41 is pivotally connected to the awning assembly 2 via a first shaft 51 , and the other end of the first link 41 is pivotally connected to the vehicle body 1 via a second shaft 52 . One end of the second link 42 is pivotally connected to the awning assembly 2 via a third shaft 53 , and the other end of the second link 52 is pivotally connected to the vehicle body 1 via a fourth shaft 54 .

In this way, a four-bar linkage mechanism is formed among the awning assembly 2 , the first link 41 , the vehicle body 1 and the second link 42 . In this embodiment, the first axis 51 , the second axis 52 , the third axis 53 and the fourth axis 54 are parallel and all extend along the left-right direction. The first connecting rod 41 is rotated backward around the second shaft 52, and the second connecting rod 42 is rotated backward around the fourth shaft 54, so that the canopy assembly 2 can be converted from the use state to the folded state. Conversely, the first connecting rod 41 is rotated forward around the second shaft 52 and the second connecting rod 42 is rotated forward around the fourth shaft 54, so that the canopy assembly 2 can be converted from the folded state to the use state.

When the awning assembly 2 is in use, the plane where the awning assembly 2 is located extends slightly downward from the front to the rear, and the first connecting rod 41 and the second connecting rod 42 are located at the rear and lower part of the awning assembly 2. The first connecting rod 41 and the second connecting rod The two connecting rods 42 both extend in the up and down direction, and the two are arranged at intervals in the front and rear directions, as shown in FIGS. 1-3 .

When the awning assembly 2 is in the folded state, the plane where the awning assembly 2 is located extends slightly downward from the front to the rear, and the first connecting rod 41 and the second connecting rod 42 both extend along the front-rear direction, and the two are arranged at intervals along the up-down direction. Both the first connecting rod 41 and the second connecting rod 42 are accommodated under the awning assembly 2 , as shown in FIGS. 9 to 11 .

In this embodiment, the link mechanisms are respectively arranged on the left and right sides, and the left and right sides of the rear part of the awning assembly 2 are respectively fixed with the first connecting piece 21, and the first connecting rod 41 and the second connecting rod 42 on both sides Both ends are fixedly provided with second connecting pieces 411 / 421 , and the second connecting pieces 411 / 421 on both sides are respectively pivotally connected to the first connecting piece 21 on the corresponding side.

The children's vehicle also includes a first locking structure for locking the canopy assembly 2 in the use state, and the first locking structure can be arranged on the structure formed by the canopy assembly 2, the first connecting rod 41, the vehicle body 1 and the second connecting rod 42. Between two parts of any pivotal connection in a four-bar linkage mechanism.

Specifically, the first locking structure includes a protrusion 211 arranged on one of the two parts pivotally connected in the above-mentioned four-bar linkage mechanism and a groove 411a arranged on the other part, and the protrusion 211 and the recess Groove 411a matches.

When the canopy assembly 2 is in use, the first locking structure is in the locked state, and the convex portion 211 is located in the groove 411a, so that the two parts that set the convex portion 211 and the groove 411a are relatively fixed, and the entire four-bar linkage mechanism is in In the locked state, the parts constituting the four-bar linkage mechanism cannot rotate relative to each other, and the canopy assembly 2 is fixed in the use state, as shown in Fig. 3 and Fig. 4 .

When the first locking structure is in the unlocked state, the convex part 211 escapes from the groove 411a, the first connecting rod 41 and the second connecting rod 42 can rotate relative to the vehicle body 1, so that the canopy assembly 2 is converted to the folded state, and at the same time , The canopy assembly 2 can also be converted to the use state when it is in the folded state, as shown in FIGS. 7 , 8 , 11 and 12 .

In this embodiment, the protrusion 211 is disposed on the first connecting member 21 , the groove 411 a is disposed on the second connecting member 411 , and at least one of the protrusion 211 and the second connecting member 411 is elastic. When the first locking structure is in the locked state and applies force to the awning assembly 2 so that the first link 41 and the second link 42 rotate relative to the vehicle body 1, the convex part 211 and/or the second connecting member 411 will be subjected to force. The elastic deformation makes the protrusion 211 disengage from the groove 411a, thereby unlocking the first locking structure. When the first locking structure is in the unlocked state, the first connecting rod 41 and the second connecting rod 42 are rotated relative to the vehicle body 1 until the position of the convex part 211 corresponds to the position of the groove 411a, the convex part 211 and/or the second connecting part 411 returns to elastic deformation, so that the protrusion 211 can be snapped into the groove 411a again, so that the first locking structure is locked.

Preferably, both the protrusion 211 and the second connecting piece 411 have elasticity.
