[0035] It should be noted that the features in the embodiments of the utility model can be combined with each other without conflict.

[0036] The trolley can be used for temporary carrying of articles, and the size of the table surface of the conventional trolley for placing articles is also fixed after being manufactured. When the number of articles cannot be carried by using one trolley, multiple trolleys need to be used for carrying or multiple times of carrying back and forth, which consumes more time or is inconvenient to use. At present, some trolleys additionally increase the carrying capacity of the trolley by setting a skip, but the supporting force of the skip is small, the loading capacity is also small, and the skip cannot be detached from the trolley body, which is poor in stability during use and cannot be flexibly detached and used.

[0037] Therefore, in the embodiments of the utility model, a trolley tail carrier and a trolley are provided, which can solve the above problems, and will be described in detail as follows.

[0038] Please refer to Figures 1 to 3 The trolley tail carrier comprises a frame body 1, a roller assembly 2 and a quick release connector 3. The roller assembly 2 is connected to the frame body 1, the roller assembly 2 bears the frame body 1 and drives the frame body 1 and articles on the frame body 1 to move together, and the quick release connector 3 is arranged on the frame body 1. The quick release connector 3 can be detachably connected with the trolley body. When the articles to be carried cannot be loaded by the original trolley, the quick release connector 3 can be connected with the trolley body, so as to increase the carrying capacity of the trolley, reduce the carrying frequency or reduce the number of trolleys used. When the trolley tail carrier is not needed, the quick release connector 3 can be directly separated from the trolley body, which is flexible and convenient to use. In addition, the trolley tail carrier has the advantages of strong supporting force and large loading capacity compared with the skip arranged on the trolley body.

[0039] The frame body 1 can be a fixed structure or a foldable structure. When the frame body 1 is a foldable structure, the overall space occupation of the stroller can be reduced, and the stroller is convenient to store. In the embodiment, the frame body 1 is a foldable structure.

[0040] Specifically, the frame body 1 includes two vertical pipes 10 and two inner support rods 11. The two vertical pipes 10 are parallel and spaced apart. The two inner support rods 11 are arranged between the two vertical pipes 10. A rod sleeve 12 is arranged between the two inner support rods 11. The two inner support rods 11 are rotatably connected to the rod sleeve 12 at one end. The other end of the two inner support rods 11 is rotatably connected to the corresponding vertical pipe 10 through a connecting seat 103. The connecting seat 103 is fixed on the vertical pipe 10. The connecting seat 103 has a plurality of hinge positions. The end of the two inner support rods 11 is hingedly connected to the corresponding connecting seat 103, so as to realize the rotatable connection. When the two inner support rods 11 are close to each other, the frame body 1 is folded. When the two inner support rods 11 are rotated and separated, the frame body 1 is unfolded.

[0041] The rod sleeve 12 is a tubular structure. One end of the rod sleeve 12 is fixed to the end of one of the two inner support rods 11 by welding or screwing. A through slot is formed in the side wall of the other end of the rod sleeve 12 along the axial direction of the rod sleeve 12. One end of the through slot penetrates the end of the rod sleeve 12. Two protruding lugs are formed on the slot wall of the through slot. A through hole is formed in the lug. A pin is rotatably arranged in the through hole. The other one of the two inner support rods 11 is inserted into the rod sleeve 12 and can rotate along the through slot. The end of the inner support rod 11 is rotatably connected to the pin. The rod sleeve 12 not only realizes the rotatable connection between the two inner support rods 11, but also limits the rotation amplitude of the two inner support rods 11, so as to ensure the stability of the stroller when it is unfolded, and prevent the stroller from suddenly shrinking when it is used. Of course, the inner support rod 11 also plays a supporting role, and is used to support and bear the objects on the stroller.

[0042] A connecting rod mechanism is arranged between the vertical pipe 10, the inner support rod 11 and the roller assembly 2. The vertical pipe 10, the inner support rod 11 and the roller assembly 2 realize synchronous movement through the connecting rod mechanism to complete folding or unfolding.

[0043] The connecting rod mechanism includes an outer support rod 5 and a sliding seat 102. The sliding seat 102 is slidably arranged in the vertical pipe 10. The two ends of the outer support rod 5 are rotatably connected to the sliding seat 102 and the roller assembly 2, respectively. The sliding seat 102 can drive the outer support rod 5 to move to drive the roller assembly 2 to fold or unfold. The outer support rod 5 is a bent pipe, which can avoid interference when the roller assembly 2 is folded.

[0044] The linkage mechanism further comprises a folding pipe assembly 4, which is arranged between the two vertical pipes 10, and the vertical pipes 10 are provided with hinged seats 101 fixed at the ends of the vertical pipes 10. The folding pipe assembly 4 comprises at least two connecting pipes 40, which are arranged in cross and rotatably connected at the cross to form an X-shaped scissor unit, and the number of the scissor units can be one or multiple, and the multiple scissor units are connected in parallel. The same side ends of the two connecting pipes 40 of the scissor unit are rotatably connected to the hinged seats 101 and sliding seats 102 respectively, so as to provide assistance when folding the frame body 1, and the sliding seats 102 slide along the vertical pipes 10 to drive the connecting pipes 40 connected thereto to move, thereby driving the entire folding pipe assembly 4 to fold or expand, so as to fold or expand the two vertical pipes 10.

[0045] The sliding seat 102 is provided with a lock catch 6 for locking or unlocking the sliding seat 102 to / from the vertical pipe 10. When the frame body 1 is folded or expanded, the lock catch 6 locks the sliding seat 102 on the vertical pipe 10, and when it is necessary to move the sliding seat 102, the lock catch 6 unlocks the sliding seat 102. The form of the lock catch 6 includes various forms, which are not limited in the embodiment, for example, the lock catch 6 can be a screw rod, and the sliding seat 102 is provided with a screw hole, and the end of the screw hole is communicated with the surface of the vertical pipe 10, and when the screw rod is arranged in the screw hole and is tightened, the sliding seat 102 is pressed on the vertical pipe 10, so as to achieve locking.

[0046] Continuing to refer to Figure 1 With Figure 2 , the roller assembly 2 is rotatably connected to the connecting seat 103 to achieve the purpose of folding the roller assembly 2.

[0047] The roller assembly 2 comprises a roller 20 and a wheel support 21, the roller 20 is mounted on the wheel support 21 and can rotate around the wheel support 21, and the end of the wheel support 21 away from the roller 20 is hinged to the hinge position of the connecting seat 103.

[0048] The wheel support 21 and the outer support rod 5 are rotatably connected by a bolt. When the sliding seat 102 moves along the vertical pipe 10, the sliding seat 102 drags the outer support rod 5 to move, and the outer support rod 5 drives the wheel support 21 and the roller 20 to rotate around the connecting seat 103, so as to complete folding or expansion.

[0049] In the embodiment, the wheel support 21 is connected to both of the connecting seats 103, so the number of the rollers 20 is at least two, and when the quick release connector 3 is connected to the body of the trolley, the trolley tail has multiple force supporting points, which is strong in support, large in carrying capacity, and high in stability, and the objects loaded on the frame body 1 are not easy to slide off.

[0050] The quick release joint 3 is arranged on the vertical pipe 10 away from the hinged seat 101, and one quick release joint 3 is arranged on each of the two vertical pipes 10, and the quick release joint 3 and the vertical pipe 10 can be fixedly connected or movably connected.

[0051] The quick release joint 3 is rotatably connected with the vehicle body of the stroller, so that the turning radius is reduced when turning, and the stroller and the stroller tail carrier are facilitated to turn.

[0052] Specifically, the quick release joint 3 has a sleeve part 30 and a rotating part 31, the sleeve part 30 is sleeved on the vertical pipe 10, and the rotating part 31 is rotatably connected to the sleeve part 30, the rotating range of the rotating part 31 is the plane where the two vertical pipes 10 are located, that is, the rotating part 31 can rotate around the sleeve part 30 within the plane range of the two vertical pipes 10, so as to be connected with strollers of different width sizes, and the rotating part 31 is further provided with a clamping piece, and the clamping piece is connected with the vehicle body of the stroller.

[0053] Of course, the structure of the quick release joint 3 can also be other forms, and the description of the quick release joint 3 is only used as an example, and the description of the quick release joint 3 will not be repeated here, and a suitable connecting joint on the market can be selected.

[0054] Reference Figure 2 When the stroller tail carrier is folded, the sliding seat 102 slides on the vertical pipe 10 in the B direction, the rod sleeve 12 and the connecting pipe 40 connected with the rod sleeve 12 move in the A direction, the two vertical pipes 10 are close to each other in the C direction, and the outer supporting rod 5 pulls the roller assembly 2 to rotate in the D direction around the connecting seat 103. Figure 3 It is a schematic view of the stroller tail carrier of the utility model embodiment when the stroller tail carrier is folded.

[0055] The stroller tail carrier of the utility model embodiment can increase the carrying capacity of the stroller, reduce the number of round trips or reduce the number of strollers used, and can be flexibly and conveniently selected in a detachable manner, and compared with the flip bucket arranged on the stroller, the stroller tail carrier of the embodiment has larger loading capacity, stronger supporting force, higher stability and better use experience.

[0056] The embodiment of the utility model further provides a stroller, which comprises the stroller tail carrier and has all the functions of the stroller tail carrier.

[0057] The above is only a specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
