[0042] The present invention provides the following description with reference to the accompanying drawings to assist in a comprehensive understanding of various embodiments of the present invention as defined by the claims and their equivalents. The description includes various specific details to assist in understanding, but these details should be considered as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present invention.
[0043] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0044] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.
[0045] An embodiment of the present invention provides a highly foldable outdoor stroller, such as Figure 1-4 As shown, the vehicle comprises a vehicle body and a handle 400. The handle 400 is mounted on the vehicle body and is retractable. When the handle 400 is needed, the handle 400 is extended to increase the length of the handle 400 for easy gripping by the user. When the handle 400 is not needed, the handle 400 is retracted.
[0046] The vehicle body includes two brackets 110, a folding structure 200, a locking structure 300 and a plurality of foldable bag bodies 120. Casters 130 are provided at the bottom of the two brackets 110. The casters 130 can reduce the friction force received by the entire outdoor cart during movement, so as to facilitate the pushing of the entire outdoor cart. The casters 130 can be universal casters or directional casters. The bag body 120 is provided between the two brackets 110. The bag body 120 is connected to the brackets 110 and / or the folding structure 200. The bag body 120 is used to place items. Since it is foldable, when the entire outdoor cart is folded and stored, the bag body 120 can also be folded and stored. The bag body 120 can specifically be a cloth bag, a paper bag or other foldable bags.
[0047] The folding structure 200 is disposed between the two brackets 110 and connected to both brackets 110. The folding structure 200 has a switchable unfolded state and a folded state. Figure 1 As shown, when the folding structure 200 is in the unfolded state, the two brackets 110 are away from each other, the entire outdoor cart is unfolded, and the user can use the outdoor cart normally. Figure 3As shown, when the folding structure 200 is in the folded state, the two brackets 110 are brought close to each other, so that the entire vehicle body is folded up.
[0048] The locking structure 300 is connected to the folding structure 200 and is used to lock the folding structure 200 in the unfolded state or to release the lock on the folding structure 200. When the locking structure 300 locks the folding structure 200 in the unfolded state, the folding structure 200 will not fold itself, ensuring that the user can use the outdoor stroller normally. After the locking structure 300 releases the lock on the folding structure 200, the folding structure 200 can be switched to the folded state, and the two brackets 110 are brought close to each other, so that the entire vehicle body can be folded up.
[0049] Therefore, when the user does not need to use the outdoor cart of this embodiment, the handle 400 is retracted, and the two brackets 110 of the body are folded together through the folding structure 200, so as to greatly reduce the volume of the entire outdoor cart, reduce space occupation, and facilitate storage and carrying.
[0050] In some embodiments, Figure 2 , Figure 5 and Figure 6 As shown, the folding structure 200 includes two connecting rod assemblies 210, which are respectively arranged at the front and rear sides of the bracket 110. The connecting rod assembly 210 includes two support rods 211 and two connecting rods 212, and the two support rods 211 are staggered to form an "X"-shaped structure. The lower ends of the two support rods 211 are respectively rotatably connected to the two brackets 110, and the middle parts of the two support rods 211 are rotatably connected to each other, and the two ends of one of the connecting rods 212 are respectively rotatably connected to one of the brackets 110 and one of the supporting rods 211, and the two ends of the other connecting rod 212 are respectively rotatably connected to the other bracket 110 and the other supporting rod 211.
[0051] When the two support rods 211 of the same connecting rod assembly 210 rotate in a direction toward each other, the angle between the two support rods 211 decreases, and the support rod 211 rotates relative to the bracket 110, driving the connecting rod 212 to rotate relative to the bracket 110. When the angle between the two support rods 211 decreases to the minimum angle that can be achieved, the folding structure 200 is in a folded state, and the two brackets 110 are close to each other; conversely, when the two support rods 211 of the same connecting rod assembly 210 rotate in a direction away from each other, the angle between the two support rods 211 increases, and the support rod 211 rotates relative to the bracket 110, driving the connecting rod 212 to rotate relative to the bracket 110. When the angle between the two support rods 211 increases to the maximum angle that can be achieved, the folding structure 200 is in an unfolded state, and the two brackets 110 are away from each other.
[0052] Further, the folding structure 200 further includes two synchronizing rods 220. Since there are two sets of link assemblies 210, the two support rods 211 rotatably connected to the same bracket 110 belong to different link assemblies 210.
[0053] The upper ends of the support rods 211 included in the two link assemblies 210 rotatably connected to one of the brackets 110 are both connected to one of the synchronizing rods 220, and the upper ends of the support rods 211 included in the two link assemblies 210 rotatably connected to the other bracket 110 are both connected to the other synchronizing rod 220. The synchronizing rod 220 and the two support rods 211 connected thereto form a structure similar to a "凵" shape.
[0054] When the two support rods 211 of one of the link assemblies 210 rotate relative to each other, due to the presence of the synchronizing rod 220, the two support rods 211 of the other link assembly 210 are correspondingly driven to rotate relative to each other. The two link assemblies 210 can act synchronously, so that the front and rear sides of the two brackets 110 can approach or move away synchronously, so as to more smoothly unfold or fold the entire outdoor cart.
[0055] Based on the above embodiments, this embodiment provides an embodiment of a locking structure, as Figure 4 、 Figure 5 and Figure 7 shown. The locking structure 300 includes a top plate 310. One end of the top plate 310 is rotatably connected to one of the synchronizing rods 220, and the other end of the top plate 310 is detachably connected to the other synchronizing rod 220. When the other end of the top plate 310 is connected to the other synchronizing rod 220, the top plate 310 and the two support rods 211 form a triangular layout, which can limit the relative rotation of the two support rods 211 of the link assembly 210, so that the folding structure 200 is kept in the unfolded state and is difficult to fold itself. When the other end of the top plate 310 is separated from the other synchronizing rod 220, the restriction between the two support rods 211 of the link assembly 210 is released, and the two support rods 211 can rotate relative to each other, and the folding structure 200 can be switched to the folded state.
[0056] Further, the top plate 310 is provided with a card slot 311 adapted to the synchronizing rod 220. The synchronizing rod 220 detachably connected to the top plate 310 is snap-fitted and fixed in the card slot 311. The detachable connection between the top plate 310 and the synchronizing rod 220 is realized by snap-fitting and fixing, which is easy to operate and more convenient for installation and disassembly.
[0057] In some embodiments, the two synchronization rods 220 are located above the two brackets 110, and the top plate 310 is also located above the two brackets 110. The top surface of the top plate 310 may not be blocked by the brackets 110. When the top plate 310 is connected to the synchronization rods 220, the user can sit on the top plate 310 or place items on the top plate 310 to increase the functionality of the outdoor cart.
[0058] Based on the above embodiment, this embodiment provides another embodiment of the locking structure, such as Figure 2 and Figure 8 As shown, the locking structure 300 includes a locking hook 320, a hanging rod 330 and an elastic mechanism 340, wherein the locking hook 320 and the hanging rod 330 are respectively arranged on the support rod 211 and the connecting rod 212 which are rotatably connected to each other, and the locking hook 320 is rotatably connected to the support rod 211. After the locking hook 320 rotates relative to the support rod 211, the locking hook 320 can be hooked on the hanging rod 330, or can be separated from the hanging rod 330. When the locking hook 320 is hooked on the hanging rod 330, the locking hook 320 restricts the support rod 211 and the connecting rod 212 from rotating relative to each other, thereby making the support rod 211 unable to rotate, and the folding structure 200 can be maintained in the unfolded state. When the locking hook 320 is separated from the hanging rod 330, the restriction on the relative rotation of the support rod 211 and the connecting rod 212 is released, thereby making the support rod 211 able to rotate, and the folding structure 200 can be switched to the folded state. At the same time, the elastic mechanism 340 is used to apply a force to the locking hook 320 so that the locking hook 320 remains hooked on the hanging rod 330, and the folding structure 200 can remain in the unfolded state and will not fold easily.
[0059] In this embodiment, the elastic mechanism 340 may be a torsion spring, which is sleeved on the rotation axes of the locking hook 320 and the support rod 211 , and two rotation arms of the torsion spring abut against the locking hook 320 and the support rod 211 respectively.
[0060] Two embodiments of the locking structure are provided above. The locking structures of the two embodiments can be used alone or in combination, or the locking structures of the two embodiments can be used simultaneously, which has a better locking effect on the folding structure 200 .
[0061] In some embodiments, Figure 1 and Figure 2 As shown, the two sides of the bag body 120 are respectively connected to the two brackets 110. When the folding structure 200 is in the unfolded state, the two brackets 110 are away from each other, and the two brackets 110 can open the bag body 120, so that the user can use the bag body 120 to load items. When the folding structure 200 is in the folded state, the two brackets 110 are close to each other, and the bag body 120 is folded accordingly, not occupying space.
[0062] In other embodiments, the front side and the rear side of the bag body are respectively connected to two connecting rod assemblies. When the folding structure is in the unfolded state, the bag body can be loaded with articles normally. When the folding structure is in the folded state, the two brackets press the bag body against each other, and the bag body can be folded.
[0063] In some embodiments, a support leg 140 is further disposed at the bottom of the bracket 110 , and the support leg 140 can provide support for the entire outdoor cart to prevent the outdoor cart from tipping over.
[0064] In some embodiments, Figure 2 and Fig. 9 As shown, the highly foldable outdoor cart of this embodiment further includes a first sleeve 510 and two rotating rods 530. The handle 400 is arranged vertically, and the user can hold the upper end of the handle 400. The first sleeve 510 is sleeved on the outside of the handle 400 and can slide vertically. The first sleeve 510 is rotatably connected to the folding structure 200. One end of the two rotating rods 530 is respectively connected to the two brackets 110, and the other end of the two rotating rods 530 is rotatably connected to the handle 400.
[0065] In this embodiment, the handle 400 is installed by two rotating rods 530 and the first sleeve 510. The first sleeve 510 plays an auxiliary supporting role to prevent the handle 400 from falling. The handle 400 can be kept in a vertical state by cooperating with the two rotating rods 540, and the handle 400 will not fall out of the first sleeve 510. When the folding structure 200 is folded, the connection position of the first sleeve 510 and the folding structure 200 will change in height due to the folding. Since the first sleeve 510 is sleeved on the outside of the handle 400 and can slide vertically, the first sleeve 510 can slide relative to the handle 400 without affecting the folding of the folding structure 200, and the first sleeve 510 can also be kept sleeved on the outside of the handle 400. At the same time, the two rotating rods 530 will also rotate towards each other when the folding structure 200 is folded, and the angle formed by the two rotating rods 530 becomes smaller. The two rotating rods 530 can also be folded along with the folding structure 200 without affecting the operation of the folding structure 200.
[0066] Furthermore, when the folding structure 200 adopts a structural design of two connecting rod assemblies 210, the two support rods 211 of one group of connecting rod assemblies 210 are both rotatably connected to the first sleeve 510, and the rotation axes of the two support rods 211 and the first sleeve 510 can be coaxially arranged with the rotation axes of the two support rods 211 rotating with each other. Specifically, the same rotation axis can be used to rotatably connect the two support rods 211 with the first sleeve 510 to simplify the rotation connection structure.
[0067] Furthermore, a second sleeve 520 is sleeved and fixed on the outer side of the handle 400, and the other ends of the two rotating rods 530 are rotatably connected to the second sleeve 520. The second sleeve 520 can provide more installation space to facilitate the rotatable connection between the rotating rod 530 and the second sleeve 520.
[0068] Hereinafter, the telescopic structure of the handle will be described in detail.
[0069] In some embodiments, Figure 10-14 As shown, the handle includes a hollow outer rod 410, a hollow inner rod 420, a movable member 440 and a stop assembly 450. The outer rod 410 is sleeved on the outer side of the lower end of the inner rod 420 and can slide along the length direction of the inner rod 420. The length of the entire telescopic handle is mainly determined by the outer rod 410 and the inner rod 420. Therefore, when the outer rod 410 and the inner rod 420 slide relative to each other, the length of the entire telescopic handle changes. When the two slide in a direction away from each other, as shown in FIG. Fig.10 As shown, the outer rod 410 and the inner rod 420 are unfolded, and the entire retractable handle is relatively long and can be used normally by the user. When the two slide toward each other, as shown in FIG. Fig.11 As shown, the outer rod 410 and the inner rod 420 are relatively retracted, and the length of the entire retractable handle is shorter, which can reduce space occupation and facilitate storage and carrying.
[0070] The upper end of the inner rod 420 is connected with a gripping member 430 for the user to hold. The user can grasp the gripping member 430 to pull or push the entire handle. The movable member 440 and the limit assembly 450 are both arranged inside the inner rod 420. The movable member 440 includes a toggle member 441 located at its upper end and a transmission member 442 located at its lower end. A portion of the toggle member 441 extends out of the outer side of the inner rod 420 and can move along the length direction of the inner rod 420. The inner rod 420 naturally needs to be provided with a corresponding slot for the toggle member 441 to extend out. Since the toggle member 441 extends out of the inner rod 420, it is convenient for the user to operate the toggle member 441 from the outside.
[0071] The limiting assembly 450 includes a limiting member 451 and an elastic device 452. The side of the inner rod 420 is provided with a through hole 401 adapted to the limiting member 451. The side of the outer rod 410 is provided with a plurality of limiting holes 411 distributed along the length direction of the inner rod 420 and adapted to the limiting member 451. There are a plurality of limiting holes 411, which is equivalent to forming a plurality of gears, so that the limiting member 451 can be extended and retracted in the through hole 401, that is, the limiting member 451 can extend out of the through hole 401 to extend to the outside of the inner rod 420, or can be retracted into the through hole 401 and not protrude from the inner rod 420. The elastic device 452 abuts against the limiting member 451 and applies an elastic force to the limiting member 451, and this force keeps the limiting member 451 in a locked state extending out of the through hole 401. When the limiting hole 411 is aligned with the through hole 401, the limiting member 451 extending out of the through hole 401 can be inserted into the limiting hole 411 to limit the inner rod 420 from sliding relative to the outer rod 410, thereby locking the inner rod 420 and the outer rod 410 together. When the toggle member 441 moves along the length direction of the inner rod 420, the transmission member 442 can drive the limiting member 451 to overcome the force of the elastic device 452 and move to an unlocked state of retracting the limiting hole 451, and the limiting member 451 will not protrude from the inner rod 420, and will not limit the inner rod 420 from sliding relative to the outer rod 410.
[0072] When using the handle of this embodiment, the user can manually move the toggle member 441, thereby driving the transmission member 442 to move, and the transmission member 442 then drives the limiting member 451 to retract the limiting hole 451, and the inner rod 420 can slide relative to the outer rod 410. The user can expand or contract the entire handle according to their own needs. When the inner rod 420 and the outer rod 410 have been adjusted to a suitable position, the limiting hole 411 is connected to the through hole 401, and then the toggle member 441 is released. Under the action of the elastic device 452, the limiting member 451 extends outward and is inserted into the limiting hole 411, and the inner rod 420 and the outer rod 410 can maintain the adjusted position and are difficult to slide easily, thereby ensuring that the user can use the handle normally.
[0073] In some embodiments, Figure 13-15 As shown, the transmission member 442 is provided with a first inclined surface 443, and the stopper 451 is provided with a second inclined surface 453 adapted to the first inclined surface 443. In the direction in which the stopper 451 extends out of the through hole 401, the heights of the first inclined surface 443 and the second inclined surface 453 gradually increase. The first inclined surface 443 is located below the second inclined surface 453 and abuts against the second inclined surface 453.
[0074] When the entire movable member 440 moves upward, the first inclined surface 443 slides along the second inclined surface 453 , which generates a lateral thrust, which enables the limiting member 451 to overcome the force of the elastic device 452 and shrink inward, so that the limiting member 451 can be retracted into the through hole 401 .
[0075] Furthermore, the transmission member 442 is provided with a transmission groove 444, both side walls of the transmission groove 444 have a first protrusion 445, and the first inclined surface 443 is provided at the top of the first protrusion 445. The limiting member 451 is inserted into the transmission groove 444, and both sides of the limiting member 451 are provided with a second protrusion 454, and the second inclined surface 453 is provided at the bottom of the second protrusion 454.
[0076] Since the limiting member 451 is inserted into the transmission groove 444, the side wall of the transmission groove 444 can play a role of lateral limiting for the limiting member 451. During the movement, the limiting member 451 will not fall to the left or right sides, ensuring its extension and contraction along the through hole 401. At the same time, two first inclined surfaces 443 and two second inclined surfaces 453 are provided. When the entire movable member 440 moves upward, lateral thrust can be generated from both sides of the limiting member 451 at the same time, so that the limiting member 451 can maintain balance and further prevent it from falling.
[0077] In some embodiments, Figure 13-15 As shown, the transmission member 442 is provided with a limiting groove 446 extending along the length direction of the inner rod 420, and the limiting assembly 450 further includes a limiting plate 455, which is inserted into the limiting groove 446 and can move along the limiting groove 446. When the transmission member 442 moves along the length direction of the inner rod 420, if the limiting plate 455 abuts against the lower end or upper end of the limiting groove 446, the limiting plate 455 will limit the transmission member 442 from continuing to move, which limits the travel of the transmission member 442 along the length direction of the inner rod 420, and prevents the transmission member 442 from moving too far upward or downward and disengaging from the limiting assembly 450, thereby ensuring that the entire mechanism can work stably and for a long time.
[0078] Furthermore, the limiting assembly 450 also includes a rear baffle 456 connected to the limiting plate 455. In the direction in which the limiting member 451 extends out of the through hole 401, the rear baffle 456 is located on the rear side of the limiting member 451. The two ends of the elastic device 452 respectively abut the rear baffle 456 and the limiting member 451 to provide an elastic force on the limiting member 451.
[0079] The limiting plate 455 and the rear baffle plate 456 can be integrally formed and can be substantially in an "L"-shaped structure. The elastic device 452 can be a spring, a spring sheet or other elastic device.
[0080] In some embodiments, Figure 13-15 As shown, the limiting assembly 450 includes a mounting seat 457, and the mounting seat 457 is fixed in the inner rod 420. The mounting seat 457 is provided with a mounting groove, the limiting member 451 and the elastic member 452 are both arranged in the mounting groove, and the transmission member 442 extends into the mounting groove.
[0081] The mounting seat 457 provides necessary installation space for the stopper 451 and the elastic device 452, so that the stopper 451, the elastic device 452 and the transmission member 442 can be assembled together organically, not in a discrete state. At the same time, the stopper 451 and the elastic device 452 can be installed in the installation groove first, the transmission member 442 can be inserted into the installation groove, and then the mounting seat 457 can be fixed to the inner rod 420, so as to facilitate the overall assembly.
[0082] The mounting seat 457 can be fixed in the inner rod 420 by various detachable methods such as snap connection, screw fixation, etc., to facilitate later maintenance.
[0083] Furthermore, the limiting plate 455 and the rear baffle plate 456 of the above embodiment are also installed in the installation groove.
[0084] In some embodiments, Fig.12 , Fig.13 and Fig.16 As shown, the inner rod 420 includes an inner rod body 421 and a sleeve joint 422, the sleeve joint 422 is sleeved and fixed on the upper end of the inner rod body 421, the outer rod 410 is sleeved on the outer side of the lower end of the inner rod body 421 and can slide along the length direction of the inner rod body 421, and the movable member 440 and the limit assembly 450 are both arranged inside the inner rod body 421. The sides of the inner rod body 421 and the sleeve joint 422 are both provided with slots 423 that are butted against each other, the toggle member 441 passes through the slots 423 of the inner rod body 421 and the sleeve joint 422 and extends to the outer side of the sleeve joint 422, and the user can operate the toggle member 441 from the outer side. The sleeve joint 422 can block the upper end opening of the inner rod body 421 to prevent the movable member 440 from being exposed, and protect the movable member 440. At the same time, the sleeve joint 422 provides space for installing the gripping member 430.
[0085] In some embodiments, the sleeve joint 422 has a clamping hole 424, and the gripping member 430 is a gripping rod clamped in the clamping hole 424. The gripping rod can extend in the lateral direction to facilitate the user's grip.
