Detailed Description
As shown in fig. 1 to 8, the stroller of the present invention includes a frame that can be converted between an unfolded state and a folded state, and the frame 100 includes a handle 1, a front leg 2, a rear leg 3, a first connecting member 4, a first sliding seat 5, a second sliding seat 6, a second connecting member 7, and a third connecting member 8; the lower side of the driver 1, the rear side of the front foot 2 and the front side of the rear foot 3 are pivoted, or two of the three are pivoted, and the other is pivoted with one of the two; the first sliding seat 5 is connected with the driver 1 and can move up and down relative to the driver 1, the second sliding seat 6 is connected with the second connecting piece 7 and can move back and forth relative to the second connecting piece 7, the first connecting piece 4 is pivoted with the rear leg 3 in a crossed manner, the upper side of the first connecting piece 4 is pivoted with the first sliding seat 5, and the lower side of the first connecting piece 4 is pivoted with the second sliding seat 6; the rear side of the second connecting piece 7 is pivoted on the rear foot 3, the front side is pivoted on the rear side of the third connecting piece 8, and the front side of the third connecting piece 8 is pivoted on the front foot 2.
When the frame 100 is in the unfolded state, the position 41 where the first connecting member 4 is pivoted to the rear leg 3 is located on the upper side of the position 71 where the rear side of the second connecting member 7 is pivoted to the rear leg 3.
When the frame 100 is in the unfolded state, the position 20 where the rear side of the front foot 2 is pivoted with the lower side of the rider 1 or/and the front side of the rear foot 3 is located on the upper side of the pivoting position 81 where the front side of the third connecting piece 8 is pivoted with the front foot 2.
The frame 100 further includes a connecting seat 31, any one of the lower side of the rider 1, the rear side of the front leg 2 and the front side of the rear leg 3 is fixedly connected with the connecting seat 31, and the other two are pivoted with the connecting seat 31, so as to achieve the purpose of connecting the three. In this embodiment, the lower side of the rider 1 and the rear side of the front leg 2 are pivotally connected to the connecting seat 31, and the front side of the rear leg 3 is fixedly connected to the connecting seat 31.
When the frame 100 is folded, the rider 1 can rotate backwards and downwards to drive the upper side of the first connecting piece 4 to rotate and move backwards and downwards, so that the first sliding seat 5 is pushed to move towards the original upper side of the rider 1, the first sliding seat 5 drives the upper side of the first connecting piece 4 to move along the rider 1, the upper side of the first connecting piece 4 simultaneously rotates relative to the first sliding seat 5, and the upper side of the first connecting piece 4 and the sliding seats simultaneously continue to rotate backwards and downwards along with the gradual rotation and movement backwards and downwards of the upper side of the rider 1; because first connecting piece 4 is the crossing pin joint with back foot 3, thereby when first connecting piece 4 upside down swivelling movement, first connecting piece 4 downside can be relatively up-moved, thereby promote second slide 6 and move toward the direction of second connecting piece 7 front side, drive second connecting piece 7 front side up swivelling movement simultaneously, and the up swivelling movement of second connecting piece 7 front side can drive third connecting piece 8 rear side also up swivelling movement, thereby third connecting piece 8 front side pull front foot 2 also back swivelling movement (as shown in fig. 6), until handlebar 1 can no longer swivelling movement, frame 100 receives and closes completely. That is, when the frame 100 is folded, only the handle 1 needs to be rotated backward and downward, and other components of the frame 100 can be linked naturally and smoothly until the frame 100 is completely folded, so that the frame 100 can be folded easily and easily. When the frame 100 is completely folded, the rider 1 and the rear leg 3 are relatively close to each other, the front leg 2 and the rear leg 3 are relatively close to each other, the included angle between the first connecting piece 4 and the rear leg 3 is reduced, and the included angle between the second connecting piece 7 and the third connecting piece 8 is reduced and relatively close to each other (as shown in fig. 7 and 8), so that the folded frame 100 is small in size and convenient to carry and store.
Preferably, a torsion spring 42 (shown in conjunction with fig. 3 and 4) is disposed between the first connecting member 4 and the rear leg 3, so that when the frame 100 is in the unfolded state, the torsion spring 42 can assist the first connecting member 4 and the front leg 2 to maintain the relatively unfolded state, thereby making the frame 100 more stable in the unfolded state; when the folded frame 100 is to be unfolded, the rider 1 is rotated upward, and the torsion spring 42 assists the first connecting member 4 to rotate and return, so that the unfolding operation of the frame 100 is easier and more convenient.
In this embodiment, the first connecting member 4, the torsion spring 42 and the rear leg 3 are passed through a pivot member, one end of the torsion spring 42 is connected to the first connecting member 4, and the other end is connected to the rear leg 3, so that the assembly is simpler and more convenient on the basis of realizing the function of the torsion spring 42.
The baby carriage further comprises a seat support 9 and a fourth connecting piece 10, wherein the front side of the seat support 9 is pivoted with the front foot 2, the rear side of the fourth connecting piece 10 is pivoted with the rear foot 3 or/and the connecting seat 31, the front side of the fourth connecting piece is pivoted with the seat support 9, and the pivoting position 90 of the seat support 9 and the front foot 2 is positioned on the front side of the pivoting position 101 of the seat support 9 and the fourth connecting piece 10. Since the front side of the rear leg 3 is fixedly connected to the connecting seat 31, the rear leg 3 and the connecting seat 31 can be regarded as a single component, and the rear side of the fourth connecting member 10 is pivoted with the rear leg 3 or pivoted with the connecting seat 31 substantially the same.
With such an arrangement, in the folding process of the frame 100, along with the backward rotation movement of the front leg 2, the front side of the seat support 9 also moves backward, so as to link the fourth connecting member 10, so that the rear side of the seat support 9 rotates downward, and the front side of the fourth connecting member 10 also rotates downward. Therefore, the folding of the frame 100 can also drive the seat support 9 to fold together, and when the frame 100 is completely folded, the included angle between the seat support 9 and the front leg 2 is greatly reduced, and the fourth connecting frame and the seat support 9 do not influence the mutual approach between the front leg 2 and the rear leg 3, and the linkage of other components of the frame 100 when the frame 100 is folded, so that the folding of the frame 100 is not influenced by the arrangement of the seat support 9 and the fourth connecting member 10, and the volume of the frame 100 after being folded is not influenced.
The pivot point 90 of the seat support 9 and the front leg 2 is located above the front side of the third link 8 and the front leg pivot point 81.
The seat 200 may be assembled on the seat support 9, the seat support 9 may be a part of the seat 200, and the seat support 9 may be provided in a tubular shape, a plate shape, or another suitable shape. Because the seat support 9 and the frame 100 are arranged as described above, the seat 200 rotates together regardless of the arrangement of the seat 200, i.e., corresponding to the folding of the frame 100. Since the seat 200 can be mounted on the seat support 9 or the seat support 9 itself can be implemented as a part of the seat 200 by using a known and feasible structure, which is not the point of the utility model, the detailed description is omitted here.
In this embodiment, it is preferable that the first connecting member 4 is provided with a supporting portion 43 at a side facing the seat supporting member 9, when the stroller is in the unfolded state, the rear side of the seat supporting member 9 abuts against the supporting portion 43 (refer to fig. 3, 4 and 5), and when the stroller frame 100 is folded, the seat supporting member 9 can be separated from the supporting portion 43. The arrangement is such that when the frame 100 is in the unfolded state, the first connecting member 4 at the rear side of the supporting frame of the seat 200 provides an upward supporting force, and when the front side of the seat support 9 is connected with the front leg 2, the front leg 2 at the front side of the seat support 9 provides an upward supporting force, so that when the frame 100 is in the unfolded state, the seat support 9 is stably supported at the front and the rear. That is, when the seat 200 is mounted on the seat support 9 or the seat support 9 itself is a part of the seat 200, the child can be stably supported and the personal safety can be secured when the child is seated in the seat 200 in the unfolded state of the stroller. Since the seat supporting member 9 can be separated from the supporting portion 43 during the folding process of the frame 100, the folding of the frame 100 and the folding of the seat supporting member 9 will not interfere with each other.
The support portion 43 is located between the pivotal connection 41 of the first link 4 and the rear leg 3 and the first slide 5 so that the seat support 9 can be located at a relatively high position relative to the frame 100 when the frame 100 is in the deployed condition, and so that a child can be located at a relatively high position when seated on the stroller of the present invention.
The seat support 9 is provided with a support portion 91 protruding from the rear side toward the first link 4, and the support portion 43 is supported by the support portion 91. In this embodiment, a supporting member 44 is fixedly connected to the first connecting member 4, and the supporting portion 43 is disposed on the supporting member 44. An abutting piece 92 is fixedly connected to the rear side of the seat support 9, and the abutting portion 91 is arranged on the abutting piece 92. This arrangement facilitates the abutment of the seat support 9 and the support portion 43 against each other and, if damaged, the replacement of the support member 44 and the abutment member 92.
In this embodiment, it is preferable that the frame further includes a push handle 11, the lower side of the push handle 11 is pivoted to the upper side of the handle 1, and when the frame is in the unfolded state, the push handle 11 and the handle 1 are unfolded relatively, so that the overall height of the frame is at a proper height, which is suitable for a parent to push the baby carriage. To further reduce the folded volume of the frame, the handle bar 11 can be rotated to approach the handle bar 1 when the frame is folded (as shown in fig. 8). And the operation of rotating the push handle 11 can be performed simultaneously when the vehicle frame is folded. In other embodiments, the pushing handle 11 may also be arranged such that the lower end thereof can be connected to the upper side of the rider 1 in a relatively vertically movable manner, and the pushing handle 11 is moved downward relative to the rider 1 until the pushing handle is immovable, that is, the height of the folded frame is reduced, thereby reducing the overall volume of the frame.
As shown in fig. 9 to 14, the stroller of the present invention further includes a seat 200 connected to the seat support 9, the seat 200 includes a seat 201, a backrest 202 whose lower side is pivoted to the seat 201, an armrest 203 whose lower side is pivoted to the seat 201, and a side rail 204 whose front side is pivoted to the armrest 203, and the rear side of the side rail 204 is pivoted to the backrest 202. The side supports 204 are provided to prevent a child seated in the seat 200 from sliding off the sides of the seat 200, thereby providing safety.
When the seat 200 is to be folded, the backrest 202 can be rotated forward, so that the rear sides of the side supporting members 204 are driven to move forward, the armrest 203 is pushed by the side supporting members 204 to move forward and downward in a rotating manner until the backrest 202 can not rotate forward and downward, and the seat 200 is completely folded, at this time, the backrest 202 is relatively close to the sitting portion 201, and the armrest 203 is also relatively close to the sitting portion 201. The side supports 204 are also relatively close to the backrest 202 and the seat 201, and the entire folded seat 200 tends to be flat and therefore small.
The seat 200 further includes a lower leg rest 205 having an upper side pivotally connected to a front side of the seating portion 201. When the seat 200 is folded, the crus rest 205 can be rotated upward to be parallel to the seat portion 201 and the backrest 202, thereby reducing the thickness of the seat 200 and further not affecting the folded volume of the entire stroller.
The seating portion 201 of the seat 200 is connected to the seat support 9.
In this embodiment, the seat 200 is arranged to be capable of being reversed back and forth relative to the frame 100, specifically, a support 1001 is fixedly connected to the seat support 9, a matching portion 2011 is arranged at the lower end of the seat portion 201 of the seat, the matching portion 2011 is connected to the support 1001 in a manner of being reversed back and forth, and the specific structure of the seat 200 reversed back and forth relative to the frame 100 can be any known and feasible structure, and is not the utility model of the present invention, and therefore, the detailed description thereof is omitted.
In order to make the folded stroller smaller in size, the seat 200 can be shifted to a position set backward relative to the frame, so that after the stroller is folded, the backrest 202 and the lower leg clip 205 are both extended in the same direction as the rear leg 3, i.e., no longer part of the whole seat extends out of the frame 100, thereby reducing the overall height of the folded stroller, i.e., reducing the volume of the folded stroller.
The stroller of the present invention further includes a front wheel 300 coupled to a front lower portion of the front leg 2 and a rear wheel 400 coupled to a rear lower portion of the rear leg 3. Preferably, the front wheel 300 is provided as a universal wheel, and the stroller can be rotated to a proper angle when folded, so that the front leg 2 and the rear leg 3 of the stroller can be reliably closer to each other, and the size of the stroller can be smaller.
In the above description of the relative orientation, the front wheel 300 is located at the front, the rear wheel 400 is located at the rear, the front wheel 300 and the rear wheel 400 are located at the lower, and the driver 1 is located at the upper. It will be appreciated that as the viewing angle changes, the relative orientations correspondingly change.
