Description

Technical Field

[0001] The present invention relates to the technical field of trolleys, and in particular to an outdoor vehicle that is convenient to fold. Background Art

[0002] With the continuous improvement of people's quality of life, during rest days after work, many people choose outdoor camping, picnicking or enjoying sunbathing on the beach. People usually transport various required tools and items (such as cooking utensils, sunshades, food, tents, drinking water, etc.) to the vicinity of the destination by car (because the destination is generally a densely populated or pristine place, so it is impossible to drive directly in), and then carry various required tools and items to the destination. To facilitate the handling of tools and items, when the car reaches the vicinity of the destination, a hand trolley / outdoor vehicle is generally used to transport the tools and items to the destination.

[0003] The styles of existing outdoor vehicles are diverse and their structures are different. Among existing patents, the Chinese patent document with the application number 202322812191.9 discloses a foldable outdoor vehicle, including a main frame and wheels. The main frame includes a front wheel frame and a rear wheel frame that are hinged to each other, and a support arm connected between the front wheel frame and the rear wheel frame; a support lock rod assembly that can control the folding and unfolding of the trolley is rotatably provided between the main frames; the front wheel frame includes a front wheel arm and a front main rod that can be folded with each other, and the rear wheel frame includes a rear wheel arm and a rear main rod that can be folded with each other; more than two U-shaped tubes are rotatably provided on the main frame. Although the outdoor vehicle in this patent document can be folded and is convenient for storage, since the support lock rod assembly is located on both sides of the outdoor vehicle and the bottom of the outdoor vehicle is completely hollow, the overall structure of the outdoor vehicle is not stable enough, the strength of the overall structure of the vehicle body is low, and the support lock rod assembly is prone to folding inadvertently, making the unfolded use of the outdoor vehicle unstable. Moreover, a storage rack that only plays a load-bearing role and does not participate in the folding process needs to be provided to support the items, making the structure complex. Therefore, the defects are very obvious and a solution is urgently needed. Summary of the Invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide an outdoor vehicle that is convenient to fold.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An outdoor vehicle that is convenient for folding, which includes a bottom frame, front wheels, two side rods, two U-shaped top frames, two rear wheels, two rear wheel support rods and four linkage rods. The bottom frame can be folded and flattened. The bottom frame includes a front U-shaped bottom frame and a rear U-shaped bottom frame. The two free ends of the front U-shaped bottom frame are respectively rotatably arranged with the two free ends of the rear U-shaped bottom frame; the front wheels are installed at the closed end of the front U-shaped bottom frame; the two U-shaped top frames can be the front U-shaped top frame and the rear U-shaped top frame respectively. The bottom ends of the two side rods are respectively rotatably connected to the outer sides of the two arms of the front U-shaped bottom frame, and the top ends of the two side rods are respectively rotatably connected to the two free ends of a U-shaped top frame (rear U-shaped top frame); the two rear wheels are respectively installed at the bottom ends of the two rear wheel support rods, and the top ends of the two rear wheel support rods are respectively rotatably connected to the two free ends of the other U-shaped top frame (front U-shaped top frame); the middle upper parts of the two side rods are respectively cross-rotatably connected to the middle upper parts of the two rear wheel support rods; between the two arms of a U-shaped top frame (rear U-shaped top frame) and the middle parts of the two rear wheel support rods, and between the two arms of the other U-shaped top frame (front U-shaped top frame) and the middle parts of the two side rods are all rotatably connected via linkage rods; the middle lower parts of the two rear wheel support rods are respectively rotatably connected to the outer sides of the two arms of the rear U-shaped bottom frame.

[0007] Further, the bottom frame further includes two adapter joints. The two adapter joints are respectively installed at the two free ends of the front U-shaped bottom frame. The two free ends of the rear U-shaped bottom frame are respectively rotatably connected to the two adapter joints. At least one adapter joint is provided with a locking mechanism, and the locking mechanism is used to lock or unlock the rear U-shaped bottom frame.

[0008] Further, the bottom surfaces of both ends of the adapter joint are concavely provided with an insertion slot and a rotation slot upwards. One free end of the front U-shaped bottom frame is inserted into the insertion slot, and one free end of the rear U-shaped bottom frame extends into the rotation slot and can rotate in the rotation slot; when the top wall of the rotation slot abuts against the free end of the rear U-shaped bottom frame, the front U-shaped bottom frame and the rear U-shaped bottom frame are unfolded and coplanar.

[0009] Further, the locking mechanism includes a base provided on the side wall of the adapter joint and a locking pin movably arranged on the base. A guide hole communicating with the rotation slot is opened on the side wall of the adapter joint. A locking hole for corresponding communication with the guide hole is opened on one arm of the rear U-shaped bottom frame. The locking pin is slidably connected to the guide hole; when the guide hole communicates with the locking hole, the locking pin can be inserted into the locking hole.

[0010] Further, the base is located on the inner side wall of the adapter joint.

[0011] Further, reinforcing rods are provided between the two arms of the front U-shaped bottom frame and between the two arms of the rear U-shaped bottom frame.

[0012] Further, the outdoor vehicle that is convenient for folding further includes a push-pull rod. The push-pull rod is installed at the middle part of the closed end of the front U-shaped bottom frame via an adapter seat. The push-pull rod can rotate relative to the adapter seat and stay at any angle.

[0013] Furthermore, there are two front wheels, and the distance between the two front wheels is smaller than the distance between the two rear wheels; the push-pull rod is located between the two front wheels.

[0014] Furthermore, the wheel diameter of the front wheel is smaller than that of the rear wheel; the front wheel adopts a universal wheel, and the rear wheel adopts a fixed wheel.

[0015] Furthermore, at least one U-shaped top frame is equipped with a foldable awning.

[0016] The beneficial effects of the present invention are as follows: in actual application, when the outdoor vehicle is in the unfolded state, the bottom frame is flattened, the front U-shaped bottom frame and the rear U-shaped bottom frame are flattened and coplanar, a side rod and a rear wheel support rod form a cross-expanded side bracket, and as the side brackets are cross-expanded, the linkage rods on the side rods support one U-shaped top frame, and the side rods on the rear wheel support rods support the other U-shaped top frame, and the two U-shaped top frames are flattened and coplanar, and the two U-shaped top frames are supported by four linkage rods, thereby ensuring the stability of the flattening of the two U-shaped top frames, and the locking mechanism locks the rear U-shaped bottom frame on the transfer joint, so that the bottom frame and the entire outdoor vehicle are in a stable and flattened state. When the outdoor vehicle needs to be folded, the locking mechanism releases the lock on the rear U-shaped chassis, applies an upward pulling force to the transfer joint, so that the transfer joint and the rear U-shaped chassis rotate relative to each other, so that the rear U-shaped chassis and the front U-shaped chassis gradually move closer and fold. As the rear U-shaped chassis and the front U-shaped chassis move closer and fold, the side bracket composed of the side rod and the rear wheel support rod will also gradually fold together, and drive the front wheel and the rear wheel to move closer to each other to fold together. As the side bracket folds, the linkage rod will swing adaptively and pull the corresponding U-shaped top frame to fold, so that one U-shaped top frame is folded together close to the side rod, and the other U-shaped top frame is folded together close to the rear wheel support rod, and the push-pull rod and the corresponding U-shaped top frame are folded together, so that the entire outdoor vehicle is completely folded. When the outdoor vehicle needs to be unfolded for use again, it is only necessary to apply a downward force to the transfer joint to gradually unfold the outdoor vehicle. When the outdoor vehicle is fully unfolded, the locking mechanism locks the rear U-shaped chassis and the transfer joint together, so that the outdoor vehicle is firmly unfolded. The bottom frame of this structural design is not only convenient for folding or unfolding of the outdoor cart, but also can directly support the items carried by the outdoor cart, has strong carrying capacity, simplifies the structure of the outdoor cart, makes the outdoor cart unfold stably, and has high strength of the overall structure; when the outdoor cart is unfolded and used, the bottom frame carries the items, because the adapter joint of the bottom frame (the folding and rotating position of the bottom frame) is located in the middle of the bottom frame, and the items will be pressed on the adapter joint, and the rotating joint is not easy to be pulled upward, so within the carrying capacity of the bottom frame, the heavier the weight of the items, the more stable the flattening of the bottom frame, thereby making the outdoor cart more firmly unfolded, and the outdoor cart is not easy to be deformed or folded accidentally.

[0023] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0024] like Figures 1 to 4As shown in the figure, an outdoor vehicle that is easy to fold provided by the present invention includes a bottom frame 1, a push rod 2, two side rods 3, two U-shaped top frames 4, two front wheels 5, two rear wheels 6, two rear wheel support rods 7, and four linkage rods 8. The two U-shaped top frames 4 can be respectively referred to as the front U-shaped top frame and the rear U-shaped top frame. The bottom frame 1 can be folded and flattened. The bottom frame 1 includes a front U-shaped bottom frame 9, a rear U-shaped bottom frame 10, and two transfer joints 11. The two transfer joints 11 are respectively installed at the two free ends of the front U-shaped bottom frame 9. The two free ends of the rear U-shaped bottom frame 10 are respectively rotatably connected to the two transfer joints 11. At least one transfer joint 11 is provided with a locking mechanism 12, and the locking mechanism 12 is used to lock or unlock the rear U-shaped bottom frame 10; the bottom end of the push rod 2 and the two front wheels 5 are installed at the closed end of the front U-shaped bottom frame 9, and the push rod 2 is located between the two front wheels 5; the bottom ends of the two side rods 3 are respectively rotatably connected to the outer sides of the two arms of the front U-shaped bottom frame 9, and the top ends of the two side rods 3 are respectively rotatably connected to the two free ends of a U-shaped top frame 4 (rear U-shaped top frame); the two rear wheels 6 are respectively installed at the bottom ends of the two rear wheel support rods 7, and the top ends of the two rear wheel support rods 7 are respectively rotatably connected to the two free ends of the other U-shaped top frame 4 (front U-shaped top frame); the middle upper parts of the two side rods 3 are respectively cross-rotatably connected to the middle upper parts of the two rear wheel support rods 7; between the two arms of a U-shaped top frame 4 (rear U-shaped top frame) and the middle parts of the two rear wheel support rods 7, and between the two arms of the other U-shaped top frame 4 (front U-shaped top frame) and the middle parts of the two side rods 3 are all rotatably connected via the linkage rods 8; the middle lower parts of the two rear wheel support rods 7 are respectively rotatably connected to the outer sides of the two arms of the rear U-shaped bottom frame 10.

[0025] In actual application, when the outdoor vehicle is in the unfolded state, the bottom frame 1 is flattened, the front U-shaped bottom frame 9 and the rear U-shaped bottom frame 10 are flattened and coplanar, a side rod 3 and a rear wheel support rod 7 form a cross-expanded side bracket, and as the side brackets are cross-expanded, the linkage rod 8 on the side rod 3 supports a U-shaped top frame 4, and the side rod 3 on the rear wheel support rod 7 supports another U-shaped top frame 4. The two U-shaped top frames 4 are flattened and coplanar, and the two U-shaped top frames 4 are supported by four linkage rods 8, thereby ensuring the stability of the two U-shaped top frames 4 when flattened. The locking mechanism 12 locks the rear U-shaped bottom frame 10 on the transfer joint 11, so that the bottom frame 1 and the entire outdoor vehicle are in a stable and flattened state. When the outdoor vehicle needs to be folded, the locking mechanism 12 releases the lock on the rear U-shaped chassis 10 and applies an upward pulling force to the transfer joint 11, so that the transfer joint 11 and the rear U-shaped chassis 10 rotate relative to each other, so that the rear U-shaped chassis 10 and the front U-shaped chassis 9 gradually move closer together and fold. As the rear U-shaped chassis 10 and the front U-shaped chassis 9 move closer together and fold, the side bracket composed of the side rod 3 and the rear wheel support rod 7 will also gradually fold together, and drive the front wheel 5 and the rear wheel 6 to move closer together to fold together, and as the side bracket is folded, the linkage rod 8 will make an adaptive swing and pull the corresponding U-shaped top frame 4 to fold, so that one U-shaped top frame 4 is folded together close to the side rod 3, and the other U-shaped top frame 4 is folded together close to the rear wheel support rod 7, and the push-pull rod 2 is folded together with the corresponding U-shaped top frame 4, so that the entire outdoor vehicle is completely folded. When the outdoor vehicle needs to be unfolded again, it is only necessary to apply a downward force to the transfer joint 11 to gradually unfold the outdoor vehicle. When the outdoor vehicle is fully unfolded, the locking mechanism 12 locks the rear U-shaped chassis 10 and the transfer joint 11 together, so that the outdoor vehicle can be unfolded stably. The bottom frame 1 of the structural design is not only convenient for the folding or unfolding of the outdoor vehicle, but also can directly support the items carried by the outdoor vehicle, has a strong carrying capacity, simplifies the structure of the outdoor vehicle, and makes the outdoor vehicle unfold stably, and has a high strength of the overall structure; when the outdoor vehicle is unfolded and used, the bottom frame 1 carries the items, because the transfer joint 11 of the bottom frame 1 (the folding and rotating position of the bottom frame 1) is located in the middle of the bottom frame 1, and the items will be pressed on the transfer joint 11, and the rotating joint is not easy to be pulled upward, so within the bearing capacity range of the bottom frame 1, the heavier the weight of the items, the more stable the flattening of the bottom frame 1, so that the outdoor vehicle is unfolded more firmly, and the outdoor vehicle is not easy to deform or fold accidentally.

[0026] Specifically, the push-pull rod 2 is a telescopic rod with adjustable length, which facilitates the adjustment of the length of the push-pull rod 2 to meet the needs of users of different heights.

[0027] In this embodiment, the bottom surfaces at both ends of the adapter joint 11 are recessed upward to form a mounting groove 13 and a rotating groove 14 communicating with the mounting groove 13. A free end of the front U-shaped chassis 9 is inserted into the mounting groove 13, and a free end of the rear U-shaped chassis 10 extends into the rotating groove 14 and can rotate within the rotating groove 14. When the top wall of the rotating groove 14 abuts against the free end of the rear U-shaped chassis 10, the front U-shaped chassis 9 and the rear U-shaped chassis 10 are unfolded and coplanar.

[0028] When the front U-shaped chassis 9 and the rear U-shaped chassis 10 are folded, the rotating groove 14 provides a rotating space for the rotation of the rear U-shaped chassis 10, which is beneficial to the compact folding of the front U-shaped chassis 9 and the rear U-shaped chassis 10 together, reducing the volume of the folded outdoor vehicle. When the front U-shaped chassis 9 and the rear U-shaped chassis 10 are flattened, the top wall of the rotating groove 14 abuts against the free end of the rear U-shaped chassis 10 to block and limit the rear U-shaped chassis 10, ensuring the stability of the bottom frame 1 after flattening. Moreover, as the weight of the items carried by the bottom frame 1 increases, the items press the adapter joint 11 downward, making the flattening of the bottom frame 1 more stable.

[0029] In this embodiment, the locking mechanism 12 includes a base 15 provided on the side wall of the adapter joint 11 and a locking pin 16 movably arranged on the base 15. A guide hole 17 communicating with the rotating groove 14 is formed in the side wall of the adapter joint 11. A locking hole 18 for corresponding communication with the guide hole 17 is formed in an arm of the rear U-shaped chassis 10. The locking pin 16 is slidably connected to the guide hole 17. When the guide hole 17 communicates with the locking hole 18, the locking pin 16 can be inserted into the locking hole 18. Specifically, the locking pin 16 can be an elastic pin, and the base 15 is U-shaped or ∪-shaped.

[0030] In practical applications, when the outdoor vehicle is unfolded, the bottom frame 1 is flattened, the front U-shaped chassis 9 and the rear U-shaped chassis 10 are unfolded and coplanar, and the guide hole 17 communicates with the locking hole 18. At this time, the locking pin 16 is inserted into the locking hole 18 to lock the adapter joint 11 and the rear U-shaped chassis 10 together, making the bottom frame 1 firmly in the flattened state. When it is necessary to fold the outdoor vehicle, the locking pin 16 is pulled out of the locking hole 18, and an upward lifting force is applied to the adapter joint 11, so that the rear U-shaped chassis 10 can rotate relative to the adapter joint 11, thereby enabling the front U-shaped chassis 9 and the rear U-shaped chassis 10 to be folded in half, and the front wheels 5 and the rear wheels 6 are also folded together.

[0031] In this embodiment, the base 15 is located on the inner side wall of the adapter joint 11, so that the locking mechanism 12 is located inside the bottom frame 1, making the structure compact. This not only prevents the locking mechanism 12 from being exposed outside and occupying space or colliding with external structures, but also prevents the accidental operation of the locking mechanism 12 from causing the folding of the outdoor vehicle.

[0032] In this embodiment, reinforcing rods 19 are provided between the two arms of the front U-shaped chassis 9 and between the two arms of the rear U-shaped chassis 10. The arrangement of the reinforcing rods 19 not only strengthens the strength of the front U-shaped chassis 9 and the rear U-shaped chassis 10, with a long service life, but also increases the weight (load-bearing capacity) of the items that the outdoor vehicle can carry.

[0033] In this embodiment, the push-pull rod 2 is installed at the middle of the closed end of the front U-shaped chassis 9 via the adapter seat 20, and the push-pull rod 2 can rotate relative to the adapter seat 20 and stay at any angle. This structural design can arbitrarily adjust the angle of the push-pull rod 2, facilitating the user to push and pull the outdoor vehicle through the push-pull rod 2.

[0034] In this embodiment, the distance between the two front wheels 5 is smaller than the distance between the two rear wheels 6. When folding, the front wheels 5 are received between the two rear wheels 6, making the structure of the folded outdoor vehicle compact and conducive to reducing the occupied space.

[0035] In this embodiment, the wheel diameter of the front wheels 5 is smaller than that of the rear wheels 6, making the structure of the folded outdoor vehicle compact and conducive to reducing the occupied space. Moreover, the front wheels 5 are universal wheels and the rear wheels 6 are directional wheels, facilitating the turning of the outdoor vehicle and enhancing its passing ability under various road conditions.

[0036] In this embodiment, at least one U-shaped top frame 4 is equipped with a foldable sunshade 21. When the sunshade 21 is unfolded, it can shade and protect the items carried by the outdoor vehicle from wind and rain; when the sunshade 21 is folded, it not only facilitates the taking and placing of the items carried by the outdoor vehicle, but also facilitates the storage of the outdoor vehicle.

[0037] Specifically, the outdoor vehicle that is easy to fold further includes a foldable vehicle body fabric, which is arranged around the edges of the bottom frame and the two U-shaped top frames.

[0038] All the technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are the preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
