Description

Children's dual-use safety vehicle

The present invention provides a dual-purpose vehicle that can be used as a safety seat or a trolley. More specifically, it has a push button that can keep the key lock at any time, and must be unlocked by a push button to make the button perform. The safety seat or trolley is switched to operate with a double-preserving synergy.

According to the "Road Traffic Management Punishment Regulations", a one-to-four-year-old child should use a safety seat in the back seat of a small car. However, the existing safety seat cannot be converted into a trolley (pram), which requires parents to prepare on the vehicle. Another trolley, in order to provide young children with the use of the car, in addition to the considerable space on the car, and there will be additional consumer spending, so the inventors developed the Chinese new application No. 200420104959 to solve the The problem can be folded into a seat, or it can be deployed into a trolley application according to actual needs. However, in the commercialization process, the patent case has found the following deficiencies and needs to be improved:

1. When it is used as a trolley, the button may be loosened due to accidental contact or running vibration, causing the entire structure to collapse in an instant, and the light will scare the young child in the ride, and there will be injuries.

Second, when it is used as a seat, it cannot effectively provide the seat belt fixing, so that it can only be used as a general seat, and the function is limited.

In view of this, the inventor has been engaged in the manufacturing development and design of related products for many years. Experience, after detailed design and careful evaluation of the above objectives, will eventually improve the above-mentioned invention.

The present invention provides a child dual-purpose safety carrier that can be used as a safety seat or a trolley, which at least includes: a seat having armrests on the left and right sides, and a cover mounted on the bottom, the cover is defined in the cover a storage space, and the back of the seat is further provided with an upper positioning portion and a lower positioning portion; a supporting arrangement having a riser fixed in parallel to the back of the seat, and having a grip for the trolley; a lever, The utility model spans two vertical pipes and can move relative to the upper positioning portion or the lower positioning portion along the relative movement of the two vertical pipes. The control rod is further recessed with a guiding groove and a chamber connecting the guiding grooves; a safety switch The button is provided with a sliding fit with the diverticulum, and the button is pushed by the first spring, and the extended buckle is located on the positioning portion or the lower positioning portion; the safety switch is further provided with a push button on the guide slot, and the push button is Pressed by the second spring to lock the button, but when the push button presses the second spring and moves to the fixed point, the button can be unlocked, so that the button can be disengaged from the positioning portion or the lower positioning portion; the wheel frame is coupled Connected between the seat and the lever, when the lever moves up When the button is buckled on the positioning portion, the wheel frame can be retracted into the storage space and the back of the seat to form a safety seat; however, when the control lever is moved down and the button is buckled to the positioning portion, the wheel carrier is Can be unfolded to form a trolley; and a binding structure, which is provided with a first pendant on each of the two armrests, and on the back of the seat The second surface is further provided with a second hanging piece, and the first and second hanging pieces each have a hook groove for the seat belt to be restrained.

Therefore, the present invention has at least the following advancement:

1. The button of the present invention further utilizes a push button to lock the button, so that the button cannot unlock the state of the positioning portion or the lower positioning portion of the buckle, and if the buckle is to be unlocked, the button must be actuated first to a fixed point. The button can be smoothly driven to release the upper positioning portion or the lower positioning portion. This double-preservation configuration can improve the risk of accidental touch or running vibration of the aforementioned patent.

2. The present invention can be additionally installed through a bundling structure and can be used as a safety seat to improve the functional deficiencies of the aforementioned patents.
