[0002] To facilitate portability and reduce space occupation when not in use, vehicles such as strollers, tow carts, and children's playpens are typically designed with a foldable structure. Existing vehicle structures vary widely, and correspondingly, the folding principles and folded forms differ. Continuous efforts by those skilled in the art aim to simplify the structure of vehicles while maintaining good load-bearing capacity, making folding operations easier, and reducing the space occupied by the folded vehicle. Summary of the Invention

[0003] The purpose of this invention is to provide a new vehicle that makes folding operations more convenient.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a carrier having an unfolded state and a folded state, the carrier including a carrier support and a push rod frame, the carrier support including two sets of support assemblies arranged opposite to each other and movably connected, and a locking assembly disposed between the two sets of support assemblies, the locking assembly including at least a locking member movable between a locked position and an unlocked position, the two sets of support assemblies being locked together when the locking member is in the locked position; the two sets of support assemblies being movable relative to each other when the locking member is in the unlocked position; the push rod frame being movably connected to the carrier support, the push rod frame being foldable along the length direction, and the push rod frame being configured such that when folded along the length direction, the locking member moves from the locked position to the unlocked position.

[0005] Preferably, the push rod holder is provided with a driving member, which moves on the push rod holder between a first position and a second position. The driving member and the locking member are configured to cooperate with each other so that when the driving member moves from the first position to the second position, it drives the locking member to move from the locked position to the unlocked position. When the push rod holder extends along the length direction, the driving member is in the first position; when the push rod holder is folded along the length direction, the driving member is in the second position.

[0006] In some embodiments, the push rod frame includes a first push rod movably connected to the vehicle support, the drive member is disposed on the first push rod, and the push rod frame further includes a push member movable relative to the first push rod. When the push rod frame is folded along its length, the push member cooperates with the drive member to move the drive member from the first position to the second position.

[0007] In some embodiments, the driving member is movably disposed on the first push rod along a length direction perpendicular to the first push rod. The driving member has a driving end located in the rod cavity of the first push rod, and the driving end is provided with a first inclined surface. The pushing member has a pushing end, and the pushing end is provided with a second inclined surface. When the push rod frame is folded along the length direction, the pushing member moves relative to the first push rod, and the second inclined surface abuts against the first inclined surface to drive the driving member to move.

[0008] In some embodiments, the push rod holder further includes a second push rod, which is slidably disposed along the length direction of the first push rod. The pusher is disposed on the second push rod. When the first push rod and the second push rod slide and shorten relative to each other, the pusher cooperates with the drive member to move the drive member from the first position to the second position.

[0009] In some embodiments, the support assembly includes at least a lower frame, with one end of two lower frames rotatably connected, a locking assembly disposed between the two lower frames, and a push rod bracket rotatably connected to one of the lower frames, or the push rod bracket and the two lower frames are rotatably connected about the same rotation center line.

When the vehicle is in an unfolded state, the support frames extend in the vertical direction, and the two lower frames extend in the front-rear direction and are supported between the two support frames. When the vehicle is in a folded state, the two lower frames are switched to extend in the vertical direction and are folded between the two support frames.

[0013] In some embodiments, the vehicle is in a folded state, the push rod frame is folded to one side of the support frame, and the push rod frame is detached from the support frame.

[0014] In some embodiments, the connecting seat is disposed on the support frame, the connecting member is provided with a hook groove, the connecting seat has a protrusion, the protrusion is slidably inserted into the hook groove, wherein the hook groove has a downwardly facing opening, so that during the process of the lower frame and the support frame rotating and closing relative to each other, the protrusion can exit from the hook groove through the opening.

[0015] In some embodiments, the support assembly further includes an upper frame, one end of which is rotatably connected to the upper part of the support frame. When the vehicle is in the unfolded state, the two upper frames cooperate with each other to form a circumferentially closed frame-shaped space.

[0043] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0044] In this article, the terms "up," "down," "front," and "rear," etc., indicate directions based on the orientation observed by the user when pushing the vehicle with the push rod in its deployed state. See details. Figure 5 The illustrative representations are for the purpose of facilitating and simplifying the description of this application, and are not intended to 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 construed as limiting the application.

[0045] Figures 1 to 18 The diagrams are drawn to scale. To keep the instructions concise, the proportions of each component are not listed individually. However, the proportions and positions of each component should be considered part of the contents of this instruction manual.

[0046] See Figures 1 to 18The vehicle shown has an unfolded state and a folded state. Specifically, the vehicle is a multi-purpose vehicle, comprising a vehicle support frame. The vehicle support frame includes two sets of support assemblies 10 that are oppositely arranged and movably connected, and a locking assembly 5 disposed between the two sets of support assemblies 10. The locking assembly 5 includes at least a locking member 51, which is movable to a locked position and an unlocked position. When the locking member 51 is in the locked position, as... Figure 14 As shown, when the locking component 5 is in the locked state, the two sets of bracket assemblies 10 are locked together, thereby allowing the vehicle bracket to be locked in the deployed state; when the locking component 51 is in the unlocked position, as shown... Figure 16 As shown, the locking component 5 is in the unlocked state at this time, and the two sets of bracket components 10 can move relative to each other, so that the vehicle bracket can switch between the unfolded state and the folded state.

[0047] The vehicle also includes a push rod holder 4, which is movably connected to the vehicle support so that it can be opened and used relative to the vehicle support or retracted relative to the vehicle support. The push rod holder 4 is foldable along its length and is configured such that when folded along its length, it causes the locking member 51 to move from a locked position to an unlocked position.

[0048] In this way, when the vehicle is in the unfolded state, the two sets of support components 10 of the vehicle support are unfolded relative to each other and locked by the locking component 5. The push rod 4 extends along the length direction and is held by the operator to drive the vehicle. When it is necessary to fold the vehicle, the push rod 4 is driven to fold along the length direction. During the folding process, the push rod 4 can drive the locking component 51 to move from the locked position to the unlocked position, that is, to unlock the locking component 5. Then, the two sets of support components 10 can be driven to move relative to each other to fold the vehicle. This simplifies the folding operation of the entire vehicle and brings convenience to the user's daily use.

[0049] Specifically, in this embodiment, the support assembly 10 includes at least a lower frame. Two lower frames are rotatably connected at one end. A locking assembly 5 is disposed between the two lower frames. The push rod bracket 4 is rotatably connected to one of the lower frames or rotatably connected to both lower frames around the same rotation center line. Here, referring to the accompanying drawings, the lower frames on the two sets of support assemblies 10 are a front lower frame 11 and a rear lower frame 12, respectively. The rear part of the front lower frame 11 is rotatably connected to the front part of the rear lower frame 12. The locking assembly 5 is disposed between the front lower frame 11 and the rear lower frame 12. The lower part of the push rod bracket 4 is rotatably connected to the rear part of the front lower frame 11 and the front part of the rear lower frame 12 around the same rotation center line, which extends in the left-right direction.

[0050] A drive member 45 is provided on the push rod holder 4. The drive member 45 moves between a first position and a second position on the push rod holder 4. When the push rod holder 4 extends along its length, the drive member 45 is in the first position; when the push rod holder 4 retracts along its length, the drive member 45 moves to the second position. The drive member 45 is configured to cooperate with the locking member 51 so that when the drive member 45 moves from the first position to the second position, it drives the locking member 51 to move from the locked position to the unlocked position. That is, when the push rod holder 4 retracts along its length, it drives the drive member 45 to move from the first position to the second position. During the above movement, the drive member 45 drives the locking member 51 to move from the locked position to the unlocked position, thereby unlocking the locking component 5.

[0051] In this embodiment, the push rod frame 4 includes a first push rod 41 and a second push rod 42 slidably disposed along its length. The first push rod 41 is connected to the carrier bracket, specifically, the lower part of the first push rod 41 is rotatably connected to the aforementioned front lower frame 11 and rear lower frame 12. The lower part of the second push rod 42 is slidably inserted into the rod cavity of the first push rod 41, thereby allowing it to slide upwards and extend relative to the first push rod 41, or slide downwards relative to the first push rod 41. A driving member 45 is disposed on the first push rod 41. The push rod frame 4 also includes a pushing member 44 disposed on the second push rod 42. When the first push rod 41 and the second push rod 42 slide downwards relative to each other, the pushing member 44 and the driving member 45 cooperate with each other, thereby causing the driving member 45 to move from a first position to a second position.

[0052] See Figure 14 and Figure 16 As shown, the driving member 45 is vertically disposed on the first push rod 41 along the length direction perpendicular to the first push rod 41. The driving member 45 has a driving end 451 located in the rod cavity of the first push rod 41, and a first inclined surface 452 is provided on the driving end 451. The pushing member 44 has a pushing end 441 located in the rod cavity of the first push rod 41, and a second inclined surface 442 is provided on the pushing end 441. When the push rod frame 4 is folded along the length direction, that is, when the first push rod 41 and the second push rod 42 slide and shorten along the length direction, the second inclined surface 442 abuts against the first inclined surface 452, thereby driving the driving member 45 to move from the first position to the second position.

[0053] In a specific configuration, the upper part of the pusher 44 is inserted into the rod cavity of the second push rod 42 and fixed to the second push rod 42. The pusher end 441 is located at the lower part of the pusher 44 and extends from below the second push rod 42 to the outside of the rod cavity of the second push rod 42.

[0054] The rear part of the front lower frame 11 has a first connecting part 111, and the rear part of the rear lower frame 12 has a second connecting part 121. The first connecting part 111, the second connecting part 121, and the lower part of the first push rod 41 are rotatably connected around the same rotation center line. The locking component 5 is disposed between the first connecting part 111 and the second connecting part 121. Specifically, it includes a locking member 51, a push slider 52, and an elastic member (not shown in the figure). The first connecting part 111 and the second connecting part 121 are each provided with a plurality of toothed grooves distributed circumferentially. The first connecting part 111 and the second connecting part 121 cooperate with each other to form a mounting cavity. The locking member 51, the push slider 52, and the elastic member are all disposed in the above mounting cavity. The locking member 51 is a toothed component with a plurality of locking teeth on the outer periphery. The plurality of locking teeth can be matched one-to-one with the toothed grooves.

[0055] When the locking member 51 is in the locked position, its two shaft ends engage with the toothed grooves on the first connecting part 111 and the second connecting part 121, respectively. At this time, the first connecting part 111 and the second connecting part 121 are locked together and cannot rotate relative to each other. When the locking member 51 is in the unlocked state, it engages only with the toothed grooves on the first connecting part 111 along the axial direction and disengages from the toothed grooves on the second connecting part 121. At this time, the first connecting part 111 and the second connecting part 121 can rotate relative to each other. The elastic element provides the force required to drive the locking member 51 toward the second connecting part 121, thereby keeping the locking member 51 in the locked position.

[0056] One end of the push slider 52 extends out of the mounting cavity and abuts against the drive member 45. Here, the drive member 45 also has a mating end 453, which is located at opposite ends of the drive end 451 along the length of the drive member 45. The outer diameter of the mating end 453 is larger than the outer diameter of the drive end 451, and the mating end 453 is located outside the rod cavity of the first push rod 41. The end of the push slider 52 extending out of the mounting cavity abuts against the mating end 453.

[0057] Therefore, when the second push rod 42 slides and shortens relative to the first push rod 41, the push member 44 drives the drive member 45 to move from the first position to the second position. The push member 44 acts on the push slider 52 through the mating end 453, and the push slider 52 drives the locking member 51 to overcome the force of the elastic member and move away from the second connecting part 121, so that the locking component 5 is unlocked.

[0058] Referring to the accompanying drawings, in this embodiment, the push rod frame 4 is provided with a connector 43, and the vehicle support is provided with a connecting seat 23. The connector 43 can be detachably connected to the connecting seat 23, so that the vehicle is in the unfolded state. The usage mode of the push rod frame 4 is determined by selecting whether to connect the connector 43 to the connecting seat 23. Specifically, in the unfolded state, the push rod frame 4 has a pushing mode and a dragging mode. When the connecting seat 23 and the connector 43 are connected to each other, fixing the push rod frame 4 relative to the vehicle support, such as Figure 1 , Figure 3 As shown, the push rod holder 4 is in the pushing mode, allowing the user to stand behind the vehicle support and hold the upper end of the push rod holder 4 to push the vehicle. When the connecting seat 23 disengages from the connecting piece 43, the push rod holder 4 can rotate relative to the vehicle support. At this time, the push rod holder 4 can be pushed according to... Figure 9 , Figure 10 The push rod 4 is flipped to the front of the vehicle and put into towing mode. The user can stand in front of the vehicle support and hold the upper end of the push rod 4 to tow the vehicle. During towing, the push rod 4 can rotate relative to the vehicle support.

[0059] Referring to the accompanying drawings, the connector 43 is slidably disposed on the push rod frame 4 along the length direction of the push rod frame 4. The connector 43 has a hook portion that can be hooked onto the connecting seat 23. When the connector 43 slides along the length direction of the push rod frame 4, the hook portion is hooked onto the connecting seat 23 or disengaged from the connecting seat 23.

[0060] See here. Figure 4 As shown, the connector 43 is slidably fitted onto the first push rod 41. The first push rod 41 has a guide post 46, and the connector 43 has a limiting groove 432. The guide post 46 is slidably inserted into the limiting groove 432 to provide sliding limitation for the connector 43 on the first push rod 41. The hook portion is a hook groove 431 on the connector 43. The connecting seat 23 has a protrusion that can be slidably inserted into the hook groove 431. Specifically, the protrusion is a stepped shaft with an end diameter larger than the main body diameter. The hook groove 431 has a downward-facing opening, allowing the larger diameter end of the protrusion to enter the hook groove 431 through the opening, thus achieving a mating connection between the connecting seat 23 and the connector 43. An elastic element (not shown in the figure) is also provided between the first push rod 41 and the connector 43 to drive the connector 43 downwards, maintaining its hook engagement with the connecting seat 23. When it is necessary to disconnect the connection between the connector 23 and the connector 43, such as Figure 7As shown, by simply driving the connector 43 to move upward along the push rod frame 4 a certain distance, it can be disengaged from the connector 23. At this time, the push rod frame 4 can be driven to rotate relative to the vehicle support to adjust the usage mode of the push rod frame 4.

[0061] Referring to the accompanying drawings, the bracket assembly 10 also includes support frames, with one end of the two support frames rotatably connected, and two lower frames rotatably connected between the lower parts of the two support frames.

[0062] Specifically, the two support frames are a front support frame 21 and a rear support frame 22. When the vehicle is in the deployed state, both the front support frame 21 and the rear support frame 22 extend inclinedly in the vertical direction. The upper part of the front support frame 21 is rotatably connected to the upper part of the rear support frame 22. A first wheel assembly 20 is provided at the lower part of the front support frame 21, and a second wheel assembly 30 is provided at the lower part of the rear support frame 22. Specifically, the first wheel assembly 20 is a universal wheel assembly, and the second wheel assembly 30 is a directional wheel assembly. The front part of the front lower frame 11 is rotatably connected to the lower part of the front support frame 21, and the rear part of the rear lower frame 12 is rotatably connected to the lower part of the rear support frame 22. When the vehicle is in the deployed state, the front lower frame 11 and the rear lower frame 12 extend along the same length direction and are supported in the front-rear direction between the lower parts of the front support frame 21 and the lower parts of the rear support frame 22.

[0063] When the vehicle is folded, the rear part of the front lower frame 11 and the front part of the rear lower frame 12 move upward, thereby causing the front support frame 21 and the rear support frame 22 to rotate relative to each other and gradually retract in the front-to-back direction. When the vehicle is in the folded state, the front lower frame 11 and the rear lower frame 12 extend in the vertical direction and retract in the front-to-back direction between the front support frame 21 and the rear support frame 22.

[0064] The connecting seat 23 is specifically set on the rear support frame 22. The above-mentioned structural arrangement of the connecting seat 23 and the connecting piece 43 also enables that even when the connecting seat 23 and the connecting piece 43 are in a mutually connected state, when the vehicle is folded, during the upward movement of the rear part of the front lower frame 11, the front part of the rear lower frame 12 and the lower part of the push rod frame 4, the rear lower frame 12 and the rear support frame 22 move closer to each other, so that the connecting piece 43 can also automatically detach from the connecting seat 23, thereby enabling the push rod frame 4 to automatically participate in the folding process of the vehicle without the need for additional flipping operation.

[0065] Referring to the accompanying drawings, the support assembly 10 also includes an upper frame, one end of which is rotatably connected to the upper part of the support frame. When the vehicle is in the unfolded state, the two upper frames cooperate with each other to form a circumferentially closed frame-shaped space.

[0066] Specifically, the two upper frames are the front upper frame 31 and the rear upper frame 32, both of which are U-shaped frames. The rear part of the front upper frame 31 is rotatably connected to the upper part of the front support frame 21, and the front part of the rear upper frame 32 is rotatably connected to the upper part of the rear support frame 22. When the vehicle is in the unfolded state, the front upper frame 31, the rear upper frame 32, the front support frame 21, the rear support frame 22, the front lower frame 11, and the rear lower frame 12 cooperate to form a carrying space for carrying people, pets, or placing items.

[0067] A first locking element is provided between the rear of the front upper frame 31 and the upper part of the front support frame 21. A first unlocking handle 311 for unlocking the first locking element is also provided at the front of the front upper frame 31, so that the angle of the front upper frame 31 can be independently adjusted when the vehicle is in the deployed state, thereby facilitating the user to enter the vehicle support. Similarly, a second locking element is provided between the front of the rear upper frame 32 and the upper part of the rear support frame 22. A second unlocking handle 321 for unlocking the second locking element is also provided at the rear of the rear upper frame 32, so that the angle of the rear upper frame 32 can be independently adjusted when the vehicle is in the deployed state, thereby facilitating the user to enter the vehicle support.

[0068] In summary, the vehicle provided in this embodiment is specifically a multi-functional vehicle that can be pushed and towed. When the vehicle is in its unfolded state, such as... Figures 1 to 10 As shown, the two sets of support components 10 of the vehicle support are unfolded relative to each other and locked by the locking component 5. The vehicle support is supported on the ground by the first wheel component 20 and the second wheel component 30. The vehicle support forms a load-bearing space through the cooperation of the two sets of support components 10, which can provide stable load-bearing support for carrying people or pets, or placing items.

[0069] When push-to-use is required, the push rod frame 4 can be fixed relative to the vehicle support by the cooperation of the connector 43 and the connecting seat 23, so that the push rod frame 4 is switched to the push-to-use mode. At this time, the user can stand behind the vehicle support and hold the upper end of the push rod frame 4 to push the vehicle. Figure 3 As shown; when it is necessary to tow the vehicle, pull the connector 43 upward to disengage it from the connector 23, and then flip the push rod frame 4 forward to switch the push rod frame 4 to the towing mode. The user can stand in front of the vehicle support and hold the upper end of the push rod frame 4 to tow the vehicle. Figure 10 As shown.

[0070] In daily use, users can also independently operate the first unlocking handle 311 and / or the second unlocking handle 321 to adjust the angle of the front upper frame 31 and / or the rear lower frame 32 as needed to meet different usage needs such as the user needing to enter and exit the carrying space on the vehicle support.

[0071] When the push rod holder 4 is in push-operation mode and the vehicle needs to be folded, it can be operated as follows: Figure 11 , Figure 12 As shown, first flip the front upper frame 31 until it folds together with the front support frame 21, then flip the rear upper frame 32 until it folds together with the rear support frame 22; subsequently, as... Figures 13 to 16 As shown, the second push rod 42 is driven to move downward, causing it to slide and shorten relative to the first push rod 41. During this process, the push member 44 at the lower part of the second push rod 42 cooperates with the drive member 45, causing the drive member 45 to move and push the push slider 52 and the locking member 51 to move, so that the locking member 51 moves from the locked position to the unlocked position, and the locking assembly 5 unlocks. At this time, as Figure 17 As shown, by using a handle or other lifting device, the rear part of the front lower frame 11 and the front part of the rear lower frame 12 are pulled upwards, causing the front lower frame 11 and the rear lower frame 12 to flip relative to each other and gradually move closer together in the front-back direction. This causes the front support frame 21 and the rear support frame 22 to gradually move closer together in the front-back direction. During this process, the distance between the lower part of the push rod frame 4 and the connection point of the front lower frame 11 and the connecting seat 23 gradually shortens, causing the connecting seat 23 to gradually detach from the hook groove 431 on the connector 43. The push rod frame 4 automatically disengages from the connection with the rear support frame 22, and then flips under its own weight to fold together with the rear lower frame 12, folding it to one side of the rear support frame 22. This completes the folding of the vehicle. The folded vehicle is as follows: Figure 18 As shown, its structure is very compact.

[0072] When the push rod frame 4 is in towing mode and the vehicle needs to be folded, the front upper frame 31 can be flipped to fold with the front support frame 21, and the rear upper frame 32 can be flipped to fold with the rear support frame 22. Then, the push rod frame 4 is driven to shorten its length and the locking component 5 is unlocked. The push rod frame 4 is then lowered so that it automatically folds with the front support frame 21. Finally, the rear of the front lower frame 11 and the front of the rear lower frame 12 are lifted upwards by the handle or other lifting components to complete the folding of the vehicle. The folding operation is also very convenient and quick.
