Description

stroller

technical field

The invention relates to a stroller for children.

Background technique

The stroller includes a stroller frame with an unfolded position and a folded position, a front wheel assembly, a left rear wheel assembly, a right rear wheel assembly, a locking mechanism for locking the stroller frame in the unfolded position, The seat arranged on the frame of the stroller, the footboard provided on the frame of the stroller for children to rest their feet, the footboard is located at the front and lower side of the seat, the pusher The vehicle frame includes a front wheel bracket located in the middle of the left and right direction, a left rear wheel bracket and a right rear wheel bracket located on the left and right sides of the front wheel bracket, and the front wheel assembly is arranged on the front wheel The lower part of the bracket, the left rear wheel assembly is arranged on the lower part of the left rear wheel bracket, and the right rear wheel assembly is arranged on the lower part of the right rear wheel bracket.

People always think that when children are sitting on the seat, the pedals for stepping on should be fixed and stable. Therefore, in the prior art, the pedals are usually fixed on the front wheel bracket. In the process of use, the child may climb into the seat of the stroller by stepping on the footboard, and in the process of climbing in, the stroller supported by the three sets of wheel assemblies may not be able to Support the weight of the child, thereby dumping to one side, there are potential safety hazards.

Correspondingly, foreign countries also have test standards. For example, if an object weighing about 20 kg is placed on one side of the pedal, the pedal of some strollers will be deformed, and some strollers with lighter weight will fall over. Foreign testing standards obviously fail.

Detailed ways

As shown in accompanying drawing 1 and accompanying drawing 5, accompanying drawing 1 and accompanying drawing 5 are the children's strollers that provide two kinds of stroller frames with different folding principles, that is, provide two embodiments of stroller frames. The two strollers of accompanying drawing 1 and accompanying drawing 5 have something in common: they include a stroller frame 1 with an unfolded position and a folded position, a front wheel assembly 2, a left rear wheel assembly 3, a right rear wheel assembly 4, The locking mechanism for locking the stroller frame 1 in the unfolded position, the seat 5 provided on the stroller frame 1, the footboard 6 provided on the stroller frame 1 for children to rest their feet, the footboard 6 Located under the front of the seat 5, the stroller frame 1 includes a front wheel support 7 positioned in the center of the left and right direction, a left rear wheel support 8 and a right rear wheel support 9 positioned on the left and right sides of the front wheel support 7, and the front wheel assembly 2 is arranged on the bottom of the front wheel bracket 7, the left rear wheel assembly 3 is arranged on the bottom of the left rear wheel bracket 8, and the right rear wheel assembly 4 is arranged on the bottom of the right rear wheel bracket 9. However, the connection relationship between the unfolded and folded rods of the cart frame 1 shown in accompanying drawing 1 and accompanying drawing 5 is different, and the folding principle of the cart frame 1 is not the main point of this case, and will not be repeated here. .

As shown in the drawings, the footboard 6 is pivotally connected to the front wheel bracket 7 through the first rotating shaft 10, and the axis line of the first rotating shaft 10 extends along the front-rear direction. There is an included angle a between the first rotating shaft 10 and the horizontal plane, and the angle range of the included angle a is from plus 80° to minus 80°, for example, the included angle a is 45°, 0° and so on.

The footboard 6 is symmetrical on the right, and the axis line of the first rotating shaft 10 is located on the symmetrical plane of the footboard 6 . Regarding the shape of the tread plate 6, as shown in accompanying drawings 1 to 3, the tread plate 6 includes a tread plate body 11, a tread plate connection formed by extending from the middle part of the tread plate body 11 to one side of the tread plate body 11. part 12, the pedal connecting part 12 is pivotally connected to the front wheel bracket 7 through the first rotating shaft 10. Not shown in the figure, it is also possible to only have the pedal body 11 without the pedal connecting portion 12 , and the pedal body 11 is pivotally connected to the front wheel bracket 7 through the first rotating shaft 10 .
