Abstract

An automatic falling mechanism for a front tray of a baby stroller, the front leg (1) is rotatably connected to the front tray (2) through the front tray shaft (4), and the upper end of the front leg (1) is fixedly connected to a connection part (3), the upper end of the rear leg (7) is rotatably connected to the connecting part (3); it is characterized in that: the front tray (2) and the connecting part (3) are provided There is a locking mechanism; when the pushcart is converted from an open state to a folded state, the locking mechanism is transformed from a locked state to an unlocked state. When the stroller is folded, the locking mechanism is automatically unlocked, and the front tray automatically falls to the folded state by virtue of gravity, so that the total volume of the folded stroller is reduced.

Description

Front tray automatic drop mechanism for baby stroller

The utility model relates to a baby stroller, in particular to a front tray of the baby stroller.

In the prior art, the front legs of a baby stroller are rotatably connected to the front tray through the front tray rotating shaft, the upper ends of the front legs are fixedly connected with connecting pieces, and the upper ends of the rear legs are connected with the connecting pieces. Rotatable connection; when the stroller is in an open state, the use surface of the front tray is roughly in a horizontal position, as shown in Figure 1, when the stroller is folded, the front tray cannot change its angle with the front legs, so The front tray needs to be removed to reduce the folded bulk of the stroller, but installing or removing the front tray is a hassle.

The purpose of the utility model is to provide a front tray automatic falling mechanism of the baby stroller in which the front tray can be as close as possible to the front legs when the stroller is folded.

The technical scheme of the utility model is: a front tray automatic falling mechanism of a baby stroller, the front legs are rotatably connected to the front tray through the front tray shaft, the upper ends of the front legs are fixedly connected with connecting parts, and the rear legs The upper end of the upper end is rotatably connected to the connecting piece; a locking mechanism is provided between the front tray and the connecting piece; when the trolley is in an open state and the locking mechanism is in a locked state, the The working surface of the front tray is roughly in a horizontal position; the cart is in the folded state and the locking mechanism is in the unlocked state, the front end of the front tray drops to a position as close as possible to the front legs; the cart is opened by When the state is converted to the folded state, the locking mechanism is transformed from the locked state to the unlocked state.

Compared with the prior art, the utility model has the following advantages:

When the cart is in an open state, the front tray can be substantially in a horizontal position and locked by the locking mechanism so that the front tray is in a stable state. When the cart is folded, the locking mechanism is automatically unlocked, and the front tray automatically falls to the folded state by gravity, so that the total volume of the cart after folding is reduced.

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Accompanying drawing 1 is the structure front view that front tray of the present utility model is in roughly horizontal working position, and cart is in open state;

Accompanying drawing 2 is the structural front view of the front tray of the utility model in the folded working position and the cart in the folded state;

Accompanying drawing 3 is the A direction view of accompanying drawing 1;

Accompanying drawing 4 is the B direction view of accompanying drawing 2;

Accompanying drawing 5 is the K-K direction view of accompanying drawing 2; Wherein:

[1], front leg; [2], front tray; [3], connecting piece; [4], front tray shaft; [5], lock column; [6], guiding slope; [7], rear leg; [8], the pivot of the front leg and the rear leg; [9], the button; [10], the spring;

Embodiment: Referring to accompanying drawings 1 to 5, a front tray automatic drop mechanism of a baby stroller, a front tray [2] is rotatably connected to the front leg [1] through the front tray shaft [4]. The upper end of the front leg [1] is fixedly connected to the connecting piece [3], and the upper end of the rear leg [7] is rotatably connected to the connecting piece [3]; the front tray [2] is connected to the A locking mechanism is provided between the connecting pieces [3]. Referring to accompanying drawing 1 and accompanying drawing 3, the trolley is in an open state and the locking mechanism is in a locked state, and the working surface of the front tray [2] is roughly in a horizontal position. Referring to accompanying drawings 2 and 4, when the cart is in the folded state and the locking mechanism is in the unlocked state, the front end of the front tray [2] drops to a position as close as possible to the front leg [1] .

Referring to accompanying drawings 3 and 4, when the cart is converted from an open state to a folded state, the locking mechanism is transformed from a locked state to an unlocked state. The locking mechanism is that the upper end of the rear leg [7] is provided with a guide slope [6], and the guide slope [6] is in contact with a lock column [5], and the lock column [5] is connected to the The connector [3] is slidingly connected. When the front leg [1] and the rear leg [7] rotate relatively around the pivot [8] of the front leg and the rear leg, the guide slope [6] pushes the lock column [5] to slide, because the A spring [10] is provided between the lock column [5] and the connector [3]. After the lock column [5] overcomes the elastic force of the spring [10], the lock column [5] axially The movement makes the locking mechanism unlock or lock; when the locking mechanism is in the locked state, one end of the lock column [5] is inserted into the front tray [2] (see accompanying drawing 3).

Claims (2)

1. An automatic falling mechanism for the front tray of a baby stroller, the front leg [1] is rotatably connected to the front tray [2] through the front tray shaft [4], and the upper end of the front leg [1] is fixedly connected There is a connecting piece [3], and the upper end of the rear leg [7] is rotatably connected to the connecting piece [3]; the feature is that: the front tray [2] and the connecting piece [3] There is a locking mechanism between them; when the trolley is in the open state and the locking mechanism is in the locked state, the working surface of the front tray [2] is roughly in the horizontal position; the cart is in the folded state and the locking mechanism is in the In the unlocked state, the front end of the front tray [2] drops to a position as close as possible to the front leg [1]; when the cart is transformed from the open state to the folded state, the locking mechanism is transformed from the locked state is unlocked. 2. The automatic falling mechanism of the front tray of the baby stroller according to claim 1, characterized in that: the locking mechanism is that the upper end of the rear leg [7] is provided with a guide slope [6], and the guide The inclined surface [6] is in contact with the lock column [5], the lock column [5] is slidingly connected with the connector [3], and the lock column [5] and the connector [3] A spring [10] is arranged between them; when the locking mechanism is in a locked state, one end of the lock column [5] is inserted into the front tray [2].
