[0032] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0033] like Figures 1-8 As shown, a portable outdoor cart is provided, including a frame structure 1, which has a switchable state and can switch between a folded state and an unfolded state.

[0034] Linkage structure 2 is installed on the frame structure 1 and is used to adjust the state transition of the frame structure 1;

[0035] Elastic structure 3 is provided on the frame structure 1 and can provide force during the folding or unfolding of the frame structure 1 to cause the state of the frame structure to change.

[0036] Control component 4 is installed on the frame structure 1 and is used to drive the action of the linkage structure 2 to realize the automatic folding or unfolding of the frame structure 1.

[0037] When the user operates the control component 4, the control component 4 drives the linkage structure 2 and the elastic structure 3 to work together to realize the automatic folding or unfolding of the frame structure 1.

[0038] Further, the control member 4 is connected with the linkage structure 2, and the frame structure 1 is automatically folded or unfolded under the cooperation and linkage of the linkage structure 2 and the elastic structure 3; wherein the frame structure 1 is composed of a bottom frame 101 and a handrail linkage assembly 102 through multiple sets of hinged pivot points to form a foldable skeleton, and forms a whole through a support frame 104 and a push hand 103; after the user triggers the control member 4, the sliding sleeve 201 vertically slides on the support frame 104, drives the bottom frame 101 and the handrail linkage assembly 102 to be folded synchronously, and automatically completes folding under the power assistance of the elastic structure 3; when the sliding sleeve 201 moves to the folding limit position, the gravity center projection of the bottom frame 101 and the handrail linkage assembly 102 is located between the two sets of support frames 104, so that the folded frame structure 1 can be kept in an upright state without additional support.

[0039] Specifically, the linkage structure 2 refers to a transmission device that transmits mechanical action, which can be realized by a connecting rod mechanism or a gear and rack assembly, and the linear motion of the control member 4 is converted into the rotation or sliding of each part of the frame. The elastic structure 3 refers to an element that stores mechanical energy and provides force, and its pre-compressed state releases energy to assist the action during folding. The control member 4 refers to a trigger device directly operated by the user, which can be realized by a button, a lever or a knob, and is connected with the linkage structure 2 through a steel wire or a connecting rod to form a mechanical transmission path of operation instructions.

[0040] When the user presses the control member 4, the steel wire pulls the sliding sleeve 201 of the linkage structure 2 to slide. The movement of the sliding sleeve 201 drives the linkage structure 2 to change the angle, so that the handrail linkage assembly 102 and the bottom frame 101 on both sides of the frame structure 1 are folded; in the unfolded state, the elastic structure 3 is kept in a stretched state, and the pre-tension maintains the stability of the frame shape, and during the whole process, the user only needs to operate the control member 4 once to trigger the continuous folding action without step-by-step adjustment of the joint position.

[0041] Compared with the prior art, the traditional stroller needs to be manually unlocked at multiple hinged points and folded step by step, while the present scheme converts multi-joint movement into single linear driving through linkage structure.

[0042] Through the above technical scheme, the present application realizes fast automatic folding under single-handed operation, solves the technical problem of complicated multi-step operation, and through the synergistic effect of mechanical linkage and elastic assistance, the folding process is more labor-saving and efficient, the compact folding form of the frame structure significantly reduces the storage space, and meets the demand for portability of outdoor equipment.

[0043] Further, as shown in Figure 1 and Figure 2 , the frame structure 1 includes a bottom frame 101 and a handrail linkage assembly 102, and the linkage structure 2 is hingedly connected with the bottom frame 101 and the handrail linkage assembly 102.

[0044] Specifically, when the user applies a folding operation, the force acting on the handrail linkage assembly 102 is synchronously transmitted to the chassis 101 through the hinge point of the linkage structure 2, and the linkage structure 2 forms a rigid connection between the chassis 101 and the handrail linkage assembly 102, so that the relative motion trajectories of the two are kept synchronous. The chassis 101 produces an inward rotational displacement under the constraint of the hinge point, while the handrail linkage assembly 102 is folded and contracted downward under the action of the same hinge point, and the force transmission path forms a linkage folding mechanism between the chassis 101 and the handrail linkage assembly 102, so that the folding actions of the two are realized in cooperation without additional operations.

[0045] Further, as shown in Figure 1 and Figure 2 , the control member 4 is arranged on the handrail linkage assembly 102, and the control member 4 drives the linkage structure 2, so that the handrail linkage assembly 102 and the chassis 101 realize mutual folding through the elastic structure 3 and the linkage structure 2.

[0046] Specifically, the control member 4 refers to an execution mechanism for triggering the folding action, which can be realized by a button or a lever, and is installed on the surface of the handrail linkage assembly 102 in a position convenient for one-handed operation. When the user presses the control member 4 on the handrail linkage assembly 102, the control member 4 triggers the motion transmission of the linkage structure 2 through mechanical linkage, and the linkage structure 2 converts the operation force into the relative displacement between the chassis 101 and the handrail linkage assembly 102. At this time, the elastic structure 3 is compressed or stretched in the folding process.

[0047] Through the above technical solution, the present application realizes the folding of the stroller by one-handed operation, and eliminates the complexity of multi-step operation. The cooperative driving mechanism of the linkage structure 2 and the elastic structure 3 effectively reduces the manual intervention required in the folding process and avoids operation errors caused by multi-joint synchronous adjustment. The rigid constraint motion path of the chassis and the handrail linkage assembly minimizes the overall volume after folding while ensuring the reliability of folding.

[0048] Further, as shown in Figure 1 and Figure 2 , the frame structure 1 further comprises a push handle 103, which is arranged on the frame structure 1 and can be turned up and down.

[0049] Specifically, the push handle 103 is a component for user holding operation, and the push handle can be adjusted in an angle range of 0-180 degrees in a vertical plane around a hinge shaft, so that the push handle 103 maintains a fixed angle when unfolded and can apply an external force to change the posture when folded.

[0050] The push handle 103 is connected with the support frame of the frame structure 1 through a rotating shaft, and in the unfolded state, the push handle is in the vertical direction to provide a holding support. When the folding action is triggered, the push handle 103 is driven to flip around the rotating shaft to the frame structure 1 direction along with the linkage structure 2, until it is flat with the frame structure 1. In this process, the flipping track of the push handle 103 is synchronized with the folding action of the bottom frame 101, and the rotating movement of the push handle is converted into the linear sliding of the sliding sleeve 201 on the support frame 104 through the fourth connecting rod 202, thereby driving the handrail linkage assembly 102 and the bottom frame 101 to fold; since the push handle 103 is directly arranged on the frame rotating node, it can be fully folded without additional disassembly steps.

[0051] Further, as shown in Figure 1 and Figure 4 , the linkage structure 2 includes a sliding sleeve 201 and a fourth connecting rod 202, and the frame structure 1 further includes a support frame 104, the sliding sleeve 201 is slidably arranged on the support frame 104, one end of the fourth connecting rod 202 is connected with the sliding sleeve 201, and the other end of the fourth connecting rod 202 is connected with the push handle 103, the fourth connecting rod 202 is flipped up and down to rotate through the push handle 103, so that the sliding sleeve 201 slides up and down on the frame structure 1, thereby driving the linkage cooperation of the linkage structure 2 and the elastic structure 3, to realize the automatic folding or unfolding of the frame structure 1;

[0052] Alternatively, the control member 4 is arranged on the push handle 103, the control member 4 is connected with the sliding sleeve 201, and the sliding sleeve 201 slides up and down on the support frame 104 through the control member 4, so as to change the state of the frame structure 1;

[0053] Alternatively, the control member 4 is arranged on the sliding sleeve 201, and the sliding sleeve 201 slides up and down on the support frame 104 through the control member 4, so as to change the state of the frame structure 1.

[0054] Specifically, when the user flips the push handle 103, no special control member 4 is arranged, and a rotating pair is directly formed by the push handle 103 and the fourth connecting rod 202, the fourth connecting rod 202 drives the sliding sleeve 201 to produce vertical displacement along the support frame 104. When the sliding sleeve 201 slides, it drives other connecting rod assemblies in the linkage structure 2 to move through the connecting point, while compressing or stretching the elastic structure 3 to store mechanical energy. When the sliding sleeve 201 moves to the preset position, the elastic structure 3 releases energy to push the bottom frame 101 and the handrail linkage assembly 102 to produce relative displacement, thereby completing automatic folding or unfolding.

[0055] In another embodiment, the control member 4 can be arranged on the push handle 103, that is, the user can press the control member 4 on the push handle 103 with one hand to release the locked state of the sliding sleeve 201, at this time the push handle 103 flips and the sliding sleeve 201 slides synchronously.

[0056] In other another embodiment, the control member 4 can be arranged on the sliding sleeve 201, and the user can adjust the position by pushing or pulling the sliding sleeve 201 itself.

[0057] Further, as shown in Figure 1 and Figure 4 , the linkage structure 2 further comprises a linkage assembly 203 hinged with the chassis 101 and a third linkage 204 hinged with the handrail linkage assembly 102, and the chassis 101 and the handrail linkage assembly 102 are folded towards each other through the linkage assembly 203 and the elastic structure 3 and the third linkage 204.

[0058] Specifically, the linkage assembly 203 refers to a mechanism capable of transmitting motion formed by connecting multiple linkage members through hinge points, and specifically, two linkage members with equal lengths can be used, and the two ends of each linkage member are hinged with the chassis 101 and the sliding sleeve 201 respectively, so as to realize the directional displacement of the chassis 101 when it is folded. The third linkage 204 functions to realize the synchronous motion transmission path.

[0059] When the user triggers the control member 4, the third linkage 204 transmits motion to the sliding sleeve 201, so that the sliding sleeve 201 generates sliding displacement on the support frame 104, and at the same time, the linkage assembly 203 drives the chassis 101 to rotate around the hinge point under the displacement action of the sliding sleeve 201. In this process, the elastic structure 3 is compressed or stretched, and the accumulated elastic potential energy is released at the folding critical point, so as to promote the chassis 101 and the handrail linkage assembly 102 to move towards the center of the support frame 104 at a synchronous angular velocity.

[0060] Further, as shown in Figure 1 and Figure 4 , the linkage assembly 203 comprises a first linkage 2031 and a second linkage 2032 hinged with each other, the first linkage 2031 is connected with the chassis 101, and the second linkage 2032 is connected with the sliding sleeve 201.

[0062] Specifically, the two independent chassis 101 are connected to form a foldable structure through a rotating pair, which can be realized by a metal hinge or a rotating shaft, so that the chassis 101 rotates relatively around the hinge point during folding, forming a linkage folding effect.

[0063] When the user triggers the folding operation, one of the chassis 101 starts to rotate under the external force, driving the other chassis 101 to rotate synchronously through the hinge point, and the elastic structure 3 is stretched or compressed in this process, storing energy to provide auxiliary power for subsequent folding action. During unfolding, the restoring force of the elastic structure 3 drives the two chassis 101 to rotate in the opposite direction until it is completely unfolded,

[0064] Further, as shown in Figure 1 and Figure 2 , the elastic structure 3 is provided with a plurality of, a plurality of elastic structure 3 in two chassis 101 staggered interval arrangement.

[0065] Specifically, staggered interval arrangement refers to the plurality of elastic structure 3 in two chassis 101 is arranged in an asymmetric or staggered manner, so as to balance the stress of each part in the folding process, different directions of elastic structure 3 are arranged between different hinge points of the chassis 101 to achieve, avoiding the plurality of elastic structure 3 in space overlap or interfere with each other.

[0066] Further, the elastic structure 3 includes a tension spring, a torsion spring, or a compression spring.

[0068] Specifically, when the support frame 104 is converted from the unfolded state to the folded state, the two groups of support frame 104 rotate around the hinge shaft, the positioning member 1041 is in contact with the chassis 101 during the folding process of the support frame 104 Displacement of the surface, forming a staggered structure with height difference. At this time, the inner side wall of the two groups of support frame 104 forms a parallel constraint surface through the limiting action of the positioning member 1041, the chassis 101 is embedded between the two groups of support frame 104 under the action of the elastic structure 3 tension, the handrail linkage assembly 102 is folded under the traction of the third connecting rod 204, the elastic structure 3 is displaced and shrunk to the gap between the support frame 104 with the chassis 101, so that the folded stroller parts remain compact arrangement.
