[0032] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments, so that the advantages and features of this utility model can be more easily understood by those skilled in the art. Obviously, the embodiments described in this application are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0033] See Figure 1 , Figure 9 The illustrated carrier has an unfolded state and a folded state. The carrier includes a base support 1, a push rod frame 2, and a linkage frame 3. The base support 1 includes a first base frame 11 and a second base frame 12 extending along a first direction. The first base frame 11 and the second base frame 12 are slidably connected along the first direction. The first base frame 11 includes a first end and a second end located at opposite ends along its length, with the first end located away from the second base frame 12. The second base frame 12 includes a third end and a fourth end located at opposite ends along its length, with the third end always located between the first end and the second end. One end of the push rod frame 2 is rotatably connected to the second end, and one end of the linkage frame 3 is rotatably connected to the third end. The other end of the linkage frame 3 is rotatably connected to the push rod frame 2. In the unfolded state, the first base frame 11 and the second base frame 12 unfold relative to each other along the first direction, and the first end and the fourth end have a first length along the first direction; that is, in this state, the base support 1 has a first length. When the vehicle is in a folded state, the push rod frame 2 is folded relative to the base support 1, and the first base frame 11 and the second base frame 12 slide and fold along the first direction. Along the first direction, the base support 1 has a second length that is less than the first length.

[0034] The carrier of the embodiment comprises a first base frame 11 and a second base frame 12 which are capable of relative sliding. When the carrier is folded, the first base frame 11 and the second base frame 12 are capable of sliding in the length direction to be folded, so that the size of the base frame 1 is reduced, thereby reducing the volume of the carrier after being folded. The carrier is provided with a linkage frame 3 between the base frame 1 and the push rod frame 2. When the push rod frame 2 is folded relative to the base frame 1, the linkage frame 3 is capable of relative folding of the first base frame 11 and the second base frame 12, thereby simplifying the folding operation.

[0035] In order to more clearly describe the relative position relationship of each component on the carrier, the up, down, left, right, front, back, inner and outer directions are defined in the direction observed by a person pushing the carrier when the carrier is in an unfolded state. In the embodiment, the first direction is the front-back direction, the first end is the front end of the first base frame 11, the second end is the rear end of the first base frame 11, the third end is the front end of the second base frame 12, and the fourth end is the rear end of the second base frame 14.

[0036] Referring to Figures 1 to 5 , the carrier is in an unfolded state, the base frame 1 extends in the front-back direction, the push rod frame 2 extends obliquely forward from top to bottom, the lower part of the push rod frame 2 is rotatably connected to the rear end of the first base frame 11 about a first rotation center line X1 which extends in the left-right direction. In the front-back direction, the front end of the second base frame 12 is always located between the front and rear ends of the first base frame 11. When the carrier is in an unfolded state, the linkage frame 3 is located on the front side of the push rod frame 2 and extends obliquely upward from front to back, the front part of the linkage frame 3 is rotatably connected to the front end of the second base frame 12, and the rear part of the linkage frame 3 is rotatably connected to the lower part of the push rod frame 2. When the carrier is folded, the push rod frame 2 is flipped forward to be folded downward relative to the base frame 1, and the second base frame 12 is slid forward and folded relative to the first base frame 11.

[0037] In the embodiment, the first base frame 11 comprises two first support rods 111 which are arranged in parallel in the second direction, and the second base frame 12 comprises two second support rods 121 which are arranged in parallel in the second direction. The second direction is perpendicular to the first direction, specifically, the second direction is the left-right direction. Referring to Figure 3 , Figure 4As shown, the first support rod 111 and the second support rod 121 both extend along the front-rear direction, the first support rod 111 has a hollow rod cavity extending along the axial direction, and the second support rod 121 is slidingly fitted in the hollow rod cavity. The linkage frame 3 is provided with a driving member for driving the second support rod 121 to slide in the hollow rod cavity, the driving member is rotatably connected to the front portion of the second support rod 121, and the driving member can slide along the first support rod 111. During the folding of the push rod frame 2 relative to the bottom support frame 1, the linkage frame 3 drives the driving member to slide forward, and the driving member drives the second support rod 121 to slide forward relative to the first support rod 111, so that the first support rod 111 and the second support rod 121 are slidably contracted together along the length direction, thereby completing the linkage folding of the bottom support frame 1.

[0038] In this embodiment, the first support rod 111 is provided with a sliding groove 113 extending along the front-rear direction and communicating with the hollow rod cavity.

In other embodiments, the first support rod 111 and the second support rod 121 are slidingly connected by using other sliding structures in the prior art, such as a sliding member and a sliding rail or a sliding member and a sliding groove.

[0040] In this embodiment, referring to Figure 2 As shown, the rear portion of the sliding groove 113 and the rear end of the first support rod 111 have a spacing, so that part of the second support rod 121 is always located in the hollow rod cavity of the first support rod 111. This not only improves the stability of the bottom support frame 1, but also facilitates the arrangement of the linkage frame 3 and facilitates the linkage of the linkage frame 3.

[0041] In this embodiment, in the left-right direction, the sliding groove 113 is arranged on the inner side of the first support frame 11, and the linkage frame 3 is located between the two first support rods 111. In this way, the size of the carrier in the left-right direction can be reduced, and after the carrier is folded, the linkage frame 3 can also be folded between the two first support rods 111, thereby reducing the size of the space occupied by the folded carrier.

[0042] In this embodiment, a first connector 114 is provided at the rear of the first base frame 11.

The rear wheel assembly 6 also includes two sets located on the left and right sides of the vehicle. Each rear wheel assembly 6 includes a rear wheel body 61 rotatably connected to the rear of the second support rod 121 about a left-right extending rear wheel axle.

[0045] In this embodiment, see Figures 5 to 7 As shown, the base support 1 extends downwards at an angle from front to back. In the projection of the vertical plane, the push rod frame 2 and the base support 1 form an obtuse angle. The center of gravity of the object being carried is located at the front of the base support 1 and on the front side of the push rod frame 2. This makes the load distribution of the vehicle more reasonable, more stable during travel, and easier for the user to push. To maintain the stability of the base support 1, in this embodiment, a horizontal support rod 112 extending in the left-right direction is also fixed between the front ends of the two first support rods 111.

[0046] In the embodiment, the carrier further comprises a support frame 4, which is located between the push rod frame 2 and the first base frame 11 in the unfolded state.

During the process, the linkage frame 3 moves forward, the driving shaft 32 slides forward in the sliding groove 113, the driving shaft 32 drives the second chassis 12 to slide forward, and the linkage frame 3 drives the sliding member 42 to slide forward relative to the support rod 41, and the sliding member 42 drives the support frame 4 to turn downward. When converting the carrier into the folded state, the push rod frame 2 can also be turned first, and after the bottom support 1, the support frame 4 and the like are folded, the push rod frame 2 itself is required to be slid and folded.

[0053] When the carrier is in the folded state, referring to Figure 9 、 Figure 10 As shown in the figure, the driving shaft 32 slides to the front part of the sliding groove 113, the push rod frame 2 and the support frame 4 are converted to extend along the front-rear direction, the push rod frame 2, the support frame 4, the linkage frame 3 and the bottom support 1 are stacked together along the up-down direction, and along the left-right direction, the support frame 4 is folded between the two first support rods 111, and the size of the carrier along the up-down direction is greatly reduced. After being folded, the first chassis 11 and the second chassis 12 of the carrier are folded together along the front-rear direction, along the front-rear direction, the push rod frame 2 and the support frame 4 are both folded between the front end part of the first chassis 11 and the rear end part of the second chassis 12, that is, the push rod frame 2 and the support frame 4 are both folded in the bottom support 1, and the size of the carrier along the front-rear direction is also reduced, and the folded carrier occupies a small space, and is convenient to store and arrange.
