Description

   Baby and toddler double seat cart assembly structure   

The invention relates to an assembly structure for a baby two-seater stroller, in particular to an assembly structure for a two-seater baby stroller with good space utilization efficiency.

An infant stroller is a common infant carrier that can easily take children to play when traveling with families, reducing the burden on many parents, and increasing the willingness of families to travel, and closer parent-child relationships. In recent years, many manufacturers have introduced lighter, easier to store, or more design-friendly stroller styles. Considering that some families have two infants and young children, there are also two-seater strollers on the market.

Conventional two-seater strollers, such as the Taiwan Patent No. M453624 patent case, allow children to ride side by side. Both can enjoy the scenery along the way. It is relatively inconvenient, and the two children may have a significant weight difference depending on their age. It is easy to shift the center of gravity in the operation, which makes it difficult to operate. It also looks clumsy and dull in appearance.

In view of the shortcomings of the left and right seat strollers, the industry has introduced another front and rear seat baby stroller. This type of stroller depends on the seating arrangement, and its impact will be reflected in the length of the vehicle body. As shown in US Patent No. US8955869B2, as shown in Figure 3 of this patent, it uses two links to connect the front and rear wheels respectively, and installs a seat cushion at a high distance from the ground at the joint of the two links, and adds an additional Install another set of frames and seats. This arrangement makes the distance between the front and back of the two seats longer, so the children in the front seat are farther away from their parents, and it is easier to locate in the dead corner of sight and not easy to look after. In addition, as in U.S. Publication No. USD616338, one of the seats is cushioned and two seats are arranged in a high and low manner. In addition to increasing the overall height of the stroller, it is difficult to place infants and toddlers due to the small space between the seats. Placed on the seat. Therefore, how to improve the shortcomings caused by poor space utilization efficiency of conventional front and rear seat type double strollers is a problem that the industry is desperate to overcome.

The purpose of the present invention is to solve the problem of poor seat space utilization efficiency in the prior art.

In order to achieve the above object, the present invention provides a baby stroller assembly structure including a first assembly portion, a second assembly portion, and a third assembly portion. The first assembly portion includes a first seat, two first frames connected to both sides of the first seat, a handle connected to each of the first frames, and a space between each of the first frames. A first accommodation area for the first seat is provided. The second assembly portion includes a second seat, two second frames connected to both sides of the second seat, a plurality of wheels connected to a side of the second frame away from the second seat, and one between each of the two A second accommodating area for the second seat is provided between the second frames. The third assembly portion includes a first connecting member connected to an end of each first frame away from the handle, a second connecting member connected to an end of each second frame away from the second seat, and each One of the first frames is inclined relative to each of the second frames to form an L-shaped arrangement.

Further, the third assembling portion includes two reinforcing rods spanned on a side adjacent to each of the first frame and each of the second frame, and two ends of each reinforcing rod are respectively connected to one of them. The first frame and one of the second frames.

Further, the third assembly portion includes a compression plate disposed between each of the reinforcing rods.

Further, the second assembly portion includes two brackets respectively connected to two sides of the second seat, and two positioning members provided on the second frame and corresponding to each of the brackets, and the second seat Each bracket is fixed to each second frame through each bracket and each positioning member.

Further, each bracket includes a longitudinal link extending from the center of the second seat toward one of the second frames, a buckle connected to one side of the longitudinal link, and a longitudinal link. And a lateral link extending away from the buckle, and a pulley connected to the end of the transverse link, each of the positioning members includes a slot provided in one of the second frames and corresponding to the buckle, and A slide rail away from the slot and accessible to the pulley for rotation.

Further, each of the positioning members includes a locking lever extending from the card slot toward another of the positioning members, each of the brackets includes a paddle, and a locking hole opened on the paddle and corresponding to the locking lever. .

Further, the first seat is pivoted on each of the first frames, and the first seat is pivotable in the first accommodation area.

Further, the second seat is pivoted on each of the second frames, and the second seat is pivotable in the second accommodation area.

Further, an inclination angle of each of the first frames with respect to each of the second frames is 55 degrees to 65 degrees.

Therefore, the present invention has the following beneficial effects over the prior art: 1. The present invention provides a two-seat stroller with a light body, a stable structure and good safety. The first frame and the second frame of the present invention are L-shaped connection method, this space configuration method can find a balance between increasing the length and height of the cart, and effectively use the periphery of the wheel, which can reduce the usage and improve the lack of poor space utilization efficiency of the conventional two-seater cart, which can improve the overall The sense of design is the pioneer of the industry.
