Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a vehicle. Background Technology

[0002] A crib consists of a bed frame and bed rails. Currently, bed frames and bed rails are usually not foldable, which results in cribs taking up a lot of space, making them inconvenient to transport and store, and leading to a poor user experience.

[0003] Existing technologies have proposed using foldable crib frames and bumpers to reduce the space occupied by the crib when folded. However, in current foldable cribs, the folding of the frame and bumpers is independent, and the folding and unfolding process is relatively cumbersome.

[0004] Therefore, there is an urgent need for a vehicle to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a vehicle that simplifies the folding and unfolding process and improves the user experience.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A vehicle having an unfolded state and a folded state, the vehicle comprising:

[0008] Support frame;

[0009] The enclosure and the support frame are located on the same side of the support frame and are rotatably configured with respect to the support frame; the support frame is foldable.

[0010] A linkage mechanism is provided between the enclosure frame and the support frame. When the enclosure frame moves closer to the support frame, the linkage mechanism drives the support frame to fold and causes the support frame to fold and move closer to the support frame.

[0011] As one possible implementation of the aforementioned carrier, the carrier frame includes a first carrier plate and a second carrier plate that are rotatably disposed relative to each other. The first carrier plate is rotatably mounted on the support frame. When the enclosure moves toward the support frame, the linkage mechanism drives the first carrier plate to fold and move toward the support frame, and causes the second carrier plate to fold and move toward the first carrier plate.

[0012] As one possible implementation of the aforementioned vehicle, the linkage mechanism includes a first link and a second link, wherein the first link is movably connected to the enclosure and the first bearing plate, and the second link is movably connected to the first link and the second bearing plate.

[0013] Alternatively, the second link can be movably connected to both the second bearing plate and the frame.

[0014] As one possible implementation of the aforementioned carrier, the enclosure is disposed opposite to the upper side of the support frame. When the enclosure is flipped downwards to approach the support frame, the first support plate is flipped upwards to approach the support frame, and the second support plate is flipped downwards to approach the first support plate. In the folded state, the support surfaces of the first support plate and the support surfaces of the second support plate are disposed opposite to each other.

[0015] As one possible implementation of the aforementioned carrier, the enclosure includes a retaining rod and an adapter disposed on the retaining rod. The adapter is rotatably mounted on the support frame via a preset rotating shaft. The first connecting rod is pivotally connected to the adapter, and the pivotal positions of the first connecting rod and the adapter are disposed on both sides of the preset rotating shaft opposite to the retaining rod, so that when the retaining rod moves toward the support frame, it drives the first connecting rod to move upward to lift the first bearing plate upward.

[0016] As one possible implementation of the aforementioned vehicle, the second link is pivotally connected to the first link, and the first bearing plate and the second bearing plate are pivotally connected to the bearing pivot shaft;

[0017] In the deployed state, a portion of the second support plate extends from the support pivot shaft to the side near the first support plate to form a first extension, and the end of the second link away from the first link is pivotally connected to the first extension.

[0018] As one possible implementation of the aforementioned carrier, the first bearing plate has a first connecting end pivotally connected to the support frame, and a second connecting end disposed away from the first connecting end;

[0019] The pivot position of the first connecting rod and the first bearing plate is located on the first bearing plate near the first connecting end.

[0020] As one possible implementation of the aforementioned vehicle, when the vehicle is in the unfolded state, in the vertical direction, the pivot position of the first connecting rod and the adapter is positioned opposite to each other on the lower side of the preset rotating shaft.

[0021] As one possible implementation of the aforementioned vehicle, a pair of enclosure frames are provided, and the pair of enclosure frames are rotatably mounted on both sides of the support frame; a pair of support frames are also provided, and the pair of support frames are rotatably mounted on both sides of the support frame.

[0022] As one possible implementation of the aforementioned vehicle, the vehicle further comprises a fabric sleeve supported between the enclosure and the support frame;

[0023] In the unfolded state, the support frame, the cloth cover, and the enclosure form a support space with an upward opening.

[0024] The beneficial effects of this utility model are:

[0025] The carrier provided by this utility model, when switching from an unfolded state to a folded state, folds the frame towards the support frame, and a linkage mechanism drives the support frame to fold and retract towards the support frame, achieving linkage between the frame movement and the support frame movement. Compared to the independent movements of the frame and support frame in the prior art, the folding of the carrier is simpler and can greatly improve the user experience. Attached Figure Description

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0040] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0043] This utility model provides a carrier, such as a folding sleeping basket, which has a folded state and an unfolded state. This carrier not only allows switching between the unfolded and folded states but also simplifies the folding and unfolding process, improving the user experience. This embodiment uses a folding sleeping basket as an example to provide a detailed description of the carrier.

[0044] It should be noted that in the following text, the vertical direction refers to the Z direction in the diagram, the X direction refers to the width direction of the folded bassinet, and the Y direction refers to the length direction of the folded bassinet. The X, Y, and Z directions are perpendicular to each other.

[0045] like Figure 1 and Figure 2 As shown, the vehicle includes a frame 1, a support frame 2, a support frame 3, and a linkage mechanism 4. The frame 1 and the support frame 2 are located on the same side of the support frame 3, and the frame 1 and the support frame 2 are rotatably mounted on the support frame 3. The support frame 2 is foldable. The linkage mechanism 4 is located between the frame 1 and the support frame 2. When the frame 1 moves closer to the support frame 3, the linkage mechanism 4 drives the support frame 2 to fold and move the support frame 2 closer to the support frame 3, so as to switch the vehicle from an unfolded state to a folded state.

[0046] like Figures 3 to 6 As shown, when the vehicle is switched from the unfolded state to the folded state, the frame 1 folds towards the support frame 3. The linkage mechanism 4 then drives the support frame 2 to fold and fold towards the support frame 3, thus achieving the linkage mechanism 4 to move the support frame 2 in conjunction with the frame 1. Compared to the independent movements of the frame 1 and the support frame 2 in the prior art, the folding of the vehicle is simpler and can greatly improve the user experience.

[0047] Furthermore, such as Figure 1 , Figures 3 to 6 As shown, the support frame 2 includes a first support plate 21 and a second support plate 22 arranged opposite to each other. The first support plate 21 is rotatably mounted on the support frame 3. When the frame 1 moves closer to the support frame 3, the linkage mechanism 4 drives the first support plate 21 to fold and move closer to the support frame 3, and causes the second support plate 22 to fold and move closer to the first support plate 21.

[0048] In this embodiment, the linkage mechanism 4 includes a first link 41 and a second link 42. The first link 41 is movably connected to the frame 1 and the first support plate 21, respectively, and the second link 42 is movably connected to the first link 41 and the second support plate 22, respectively.

[0049] Specifically, the enclosure 1 and the support frame 2 are both located on the same side of the support frame 3 in the Y direction. When the vehicle is in the unfolded state, the enclosure 1 is positioned on the upper side of the support frame 2. When the vehicle is in the unfolded state, the bearing surfaces of the first bearing plate 21 and the second bearing plate 22 are both facing upwards. The two bearing surfaces are used together for bearing, resulting in a large bearing area that can meet the user's bearing needs.

[0050] For example, when the carrier is in the unfolded state, the bearing surfaces of the first bearing plate 21 and the second bearing plate 22 are on the same horizontal plane. When used as a folding sleeping basket, uneven bearing surfaces can be avoided from affecting the user experience.

[0051] When the frame 1 is flipped downwards to move closer to the support frame 3, the first bearing plate 21 is flipped upwards to move closer to the support frame 3, and the second bearing plate 22 is flipped downwards to move closer to the first bearing plate 21; when the vehicle is in a folded state, the bearing surfaces of the first bearing plate 21 and the second bearing plate 22 are set opposite to each other.

[0052] When the vehicle is in a folded state, the bearing surfaces of the first bearing plate 21 and the second bearing plate 22 are arranged opposite to each other, so that the first bearing plate 21 is folded between the second bearing plate 22 and the support frame 3, thereby reducing the space occupied by the vehicle after folding.

[0053] It should be noted that both the first bearing plate 21 and the second bearing plate 22 mentioned above adopt a flat plate structure, and can also adopt a hollow structure formed by multiple rods.

[0054] In other embodiments, the second connecting rod 42 can be movably connected to the second bearing plate 22 and the frame 1 respectively. Specifically, the two ends of the second connecting rod 42 are pivotally connected to the second bearing plate 22 and the frame 1 respectively, and the second connecting rod 42, the frame 1 and the second bearing plate 22 are located on the same side of the support frame 3, so that when the frame 1 is flipped downward, the frame 1 drives the second bearing plate 22 to flip downward through the second connecting rod 42.

[0055] In this embodiment, as Figure 1 , Figures 3 to 6As shown, the enclosure 1 includes a retaining rod 12 and an adapter 11 disposed on the retaining rod 12. The adapter 11 is rotatably mounted on the support frame 3 via a preset rotating shaft 100. The first connecting rod 41 is pivotally connected to the adapter 11, and the pivot position of the first connecting rod 41 and the adapter 11 is disposed on both sides of the preset rotating shaft 100 opposite to the retaining rod 12, so that when the retaining rod 12 moves closer to the support frame 3, it drives the first connecting rod 41 to rotate upward to lift the first bearing plate 21 upward.

[0056] Specifically, the preset rotating shaft 100 extends along the X direction, and the first connecting rod 41 is pivotally connected to the adapter 11. The pivot axis of the first connecting rod 41 and the adapter 11 is referred to as the second pivot axis 300. The second pivot axis 300 extends along the X direction, and the surrounding rod 12 and the second pivot axis 300 are located on opposite sides of the preset plane 800. The second pivot axis 300 is located on the preset plane 800 and the preset plane 800 is perpendicular to the Y direction. In other words, the second pivot axis 300 and the surrounding rod 12 are arranged on both sides of the preset rotating shaft 100 in the Y direction.

[0057] For ease of understanding, the pivot position of the first link 41 and the adapter 11 in the folded state of the vehicle is referred to as the folded pivot position; the pivot position of the first link 41 and the adapter 11 in the unfolded state of the vehicle is referred to as the unfolded pivot position. The folded pivot position and the unfolded pivot position are always located on the same side of the support frame 3 in the Y direction. Regardless of whether it is in the unfolded state or the folded state, the surrounding rod 12 is always located on the other side of the support frame 3 in the Y direction.

[0058] When the retaining rod 12 rotates downward to fold towards the support frame 3, the second pivot shaft 300 will rotate around the preset pivot shaft 100 and be lifted upward under the action of the adapter 11, so that the first connecting rod 41 rotates upward to lift the first bearing plate 21.

[0059] Furthermore, such as Figure 1 and Figure 3 As shown, when the vehicle is in the deployed state, in the vertical direction, the pivot position of the first connecting rod 41 and the adapter 11 is positioned opposite each other on the lower side of the preset rotating shaft 100. In other words, when the vehicle is in the deployed state, the second pivot shaft 300 is located below the preset rotating shaft 100, and since the second pivot shaft 300 and the surrounding rod 12 are located on both sides of the preset rotating shaft 100 in the Y direction, when the surrounding rod 12 rotates downward to fold towards the support frame 3, the first connecting rod 41 rotates upward to lift the first bearing plate 21.

[0060] like Figure 6 As shown, when the vehicle is in the folded state, in the vertical direction, the pivot position of the first link 41 and the adapter 11 is above the preset pivot 100. In other words, when the vehicle is in the folded state, the second pivot 300 is located above the preset pivot 100.

[0061] like Figures 3 to 6As shown, during the transition of the vehicle from the unfolded state to the folded state, the acute angle between the first link 41 and the support frame 3 gradually increases. When the central axis of the preset rotating shaft 100 and the central axis of the second pivot shaft 300 are horizontal and coplanar, the acute angle between the first link 41 and the support frame 3 is at its maximum. As the height of the second pivot shaft 300 continues to increase, the acute angle between the first link 41 and the support frame 3 gradually decreases. This is beneficial for increasing the width of the entire vehicle along the Y direction after folding, thereby reducing the space occupied by the folded vehicle.

[0062] Furthermore, such as Figure 1 , Figures 3 to 6 As shown, the second link 42 is pivotally connected to the first link 41, and the first bearing plate 21 and the second bearing plate 22 are pivotally connected to the bearing pivot shaft 700. When the vehicle is in the deployed state, part of the second bearing plate 22 extends and is disposed on the side of the bearing pivot shaft 700 close to the first bearing plate 21 to form a first extension 221, and the end of the second link 42 away from the first link 41 is pivotally connected to the first extension 221.

[0063] Specifically, a second extension 213 is provided on the side of the first support plate 21 that connects to the second support plate 22. The second extension 213 is located between the two first extensions 221. The second extension 213 is pivotally connected to the two first extensions 221 via a support pivot shaft 700. The outer first extension 221 is pivotally connected to the second connecting rod 42 via a fifth pivot shaft 600.

[0064] For example, the second extension 213 is mounted to the first support plate 21 by fasteners, and the first extension 221 is mounted to the second support plate 22 by fasteners. In other embodiments, the first support plate 21 and the second extension 213 may be integrally formed, and the first extension 221 and the second support plate 22 may be integrally formed.

[0065] For ease of description, the pivot axis of the second link 42 and the first link 41 is referred to as the fourth pivot axis 500, and the pivot axis of the second link 42 and the first extension 221 is referred to as the fifth pivot axis 600. The fourth pivot axis 500, the fifth pivot axis 600 and the bearing pivot axis 700 all extend along the X direction.

[0066] Regardless of whether the vehicle is in the deployed or folded state, the load-bearing pivot 700 is always located below the fifth pivot 600 in the vertical direction. In the deployed state, the fifth pivot 600 is closer to the support frame 3 along the Y direction than the load-bearing pivot 700; in the folded state, the load-bearing pivot 700 is closer to the support frame 3 along the Y direction than the fifth pivot 600.

[0067] Along the extension direction of the first link 41, the fourth pivot 500 is located between the third pivot 400 and the second pivot 300, with the third pivot 400 being closer to the fourth pivot 500 than the second pivot 300.

[0068] When the first link 41 lifts the first bearing plate 21 to rotate upward, the second link 42 rotates upward around the fourth pivot shaft 500 under the combined action of the first link 41 and the first bearing plate 21. This causes the second bearing plate 22 to rotate downward around the bearing pivot shaft 700 under the combined action of the first bearing plate 21 and the second link 42. As a result, the bearing surfaces of the first bearing plate 21 and the second bearing plate 22 are opposite to each other, so that the first bearing plate 21 is folded in the Y direction between the support frame 3 and the second bearing plate 22.

[0069] Furthermore, such as Figure 1 , Figures 3 to 6 As shown, the first bearing plate 21 has a first connecting end 211 pivotally connected to the support frame 3, and a second connecting end 212 disposed away from the first connecting end 211; the first connecting end 211 is closer to the pivot position between the first connecting rod 41 and the first bearing plate 21 than the second connecting end 212.

[0070] Specifically, for ease of understanding, the pivot axis between the first bearing plate 21 and the support frame 3 is designated as the first pivot axis 200, and the pivot axis between the first connecting rod 41 and the first bearing plate 21 is designated as the third pivot axis 400. Both the first pivot axis 200 and the third pivot axis 400 extend along the X direction. The first pivot axis 200 is located at the first connecting end 211 of the first bearing plate 21. The bearing pivot axis 700, which pivots the second bearing plate 22 and the first bearing plate 21, is located at the second connecting end 212 of the first bearing plate 21. The third pivot axis 400 is located between the bearing pivot axis 700 and the first pivot axis 200, with the first pivot axis 200 being closer to the third pivot axis 400 than the bearing pivot axis 700.

[0071] Setting the first connecting end 211 closer to the pivot position between the first connecting rod 41 and the first bearing plate 21 than the second connecting end 212 allows the first connecting rod 41 to rotate upward to lift the first bearing plate 21. This ensures that while the first bearing plate 21 is folded between the second bearing plate 22 and the support frame 3 along the Y direction, the rotation amplitude of the first connecting rod 41 is reduced, the center distance between the second pivot shaft 300 and the preset rotating shaft 100 is reduced, thereby reducing the size of the adapter 11. It also facilitates the first connecting rod 41 to act on the second connecting rod 42, so that the second connecting rod 42 and the first bearing plate 21 cooperate to flip the second bearing plate 22 downward.

[0072] Furthermore, such as Figure 1As shown, a pair of enclosure frames 1 are provided, and the pair of enclosure frames 1 are rotatably fixed on opposite sides of the support frame 3; a pair of bearing frames 2 are also provided, and the pair of bearing frames 2 are rotatably fixed on opposite sides of the support frame 3.

[0073] Specifically, two enclosure frames 1 are distributed on both sides of the support frame 3 in the Y direction, and the bearing frames 2 are correspondingly distributed on both sides of the support frame 3 in the Y direction. The first bearing plate 21 is pivotally connected at both ends of the first bearing plate 21 in the X direction to the lower ends of the two support frames 3 in the Y direction via a first pivot shaft 200, and the two first pivot shafts 200 connected to the first bearing plate 21 are coaxially arranged. The first bearing plate 21 is also pivotally connected at both ends of the first bearing plate 21 in the X direction to the corresponding second bearing plate 22 in the X direction via a fourth pivot shaft 500, and the two fourth pivot shafts 500 connected to the same second bearing plate 22 are coaxially arranged.

[0074] By setting up two enclosure frames 1 and two support frames 2, the bearing area formed by the bearing surfaces of the two first support plates 21 and the two second support plates 22 when the vehicle is in the unfolded state can be increased to meet user needs. Moreover, the two support frames 2 are respectively set on both sides of the support frame 3, which can improve the stability of the vehicle along the Y direction when the vehicle is in the unfolded state, as the support frame 3 simultaneously provides support for the two support frames 2.

[0075] For example, the structures on both sides of the support frame 3, such as the bearing frame 2, the linkage mechanism 4, and the enclosure 1, are arranged in a rotationally symmetrical manner. Specifically, the bearing frame 2, the linkage mechanism 4, and the enclosure 1 on either side of the support frame 3 can be rotated by 180° to obtain the bearing frame 2, the linkage mechanism 4, and the enclosure 1 on the other side of the support frame 3.

[0076] When the vehicle is in the deployed state, the bearing pivot 700, the fifth pivot 600, the third pivot 400 and the first pivot 200 are all located below the bearing surface of the first bearing plate 21 and the bearing surface of the second bearing plate 22, so as to avoid the arrangement of each pivot affecting the use of the bearing surface.

[0077] Furthermore, such as Figure 3 , Figure 6 and Figure 7 As shown, the adapter 11 is provided with a clearance part, which has an unfolding limiting surface 1111 and a folding limiting surface 1112. The first connecting rod 41 is limited between the unfolding limiting surface 1111 and the folding limiting surface 1112. When the vehicle is in the unfolded state, the first connecting rod 41 abuts against the unfolding limiting surface 1111; when the vehicle is in the folded state, the first connecting rod 41 abuts against the folding limiting surface 1112. This can limit the position of the first connecting rod 41 when the vehicle is unfolded and folded.

[0078] In this embodiment, the clearance portion is a clearance groove 111 provided on the adapter 11, and the unfolding limiting surface 1111 and the folding limiting surface 1112 are both inner walls of the clearance groove 111. Exemplarily, the adapter 11 is generally a disc-shaped structure with the axial direction of the disc-shaped structure being X-direction. The clearance groove 111 is formed on the axial end face of the adapter 11, and one side of the clearance groove 111 extends radially along the adapter 11 to the outer peripheral wall of the adapter 11. The unfolding limiting surface 1111 is planar, and the folding limiting surface 1112 is arc-shaped. The first connecting rod 41 is provided with an unfolding mating surface 411 and a folding mating surface 412, with the folding mating surface 412 located at the end of the first connecting rod 41. When the vehicle is in the unfolded state, the unfolding mating surface 411 abuts against the unfolding limiting surface 1111; when the vehicle is in the folded state, the folding limiting surface 1112 abuts against the folding mating surface 412.

[0079] Furthermore, such as Figure 1 As shown, the two first support plates 21 are spaced apart along the Y direction, which can avoid interference between the two support frames 2 when the vehicle is folded and provide space for the rotation of the two first support plates 21.

[0080] Furthermore, the two enclosure frames 1 are connected to the two support frames 2 through the linkage mechanism 4. When any enclosure frame 1 moves closer to the support frame 3 to fold, the enclosure frame 1 can drive the two support frames 2 and the other enclosure frame 1 to move closer to the support frame 3 through the linkage mechanism 4 to fold, so as to switch the vehicle from the unfolded state to the folded state.

[0081] This vehicle connects two frames 1 to two support frames 2 via a linkage mechanism 4. When either frame 1 folds towards the support frame 3, the linkage mechanism 4 simultaneously causes the two support frames 2 to fold towards the support frame 3. At the same time, the linkage mechanism 4 also causes the other frame 1 to fold towards the support frame 3, thus achieving a linkage between the movement of one frame 1 and the movements of the other frame 1 and the two support frames 2. Compared to existing technologies, the folding mechanism is simpler and significantly improves the user experience.

[0082] Furthermore, the linkage mechanism 4 includes two first links 41 and two second links 42, which are arranged in a one-to-one correspondence. The two first links 41 are also arranged in a one-to-one correspondence with the two support frames 2 and the two enclosure frames 1. The linkage mechanism 4 also includes a synchronous linkage structure for controlling the linkage of the two first links 41. The synchronous linkage structure is slidably connected to the two first links 41 respectively, so that when any one of the first links 41 moves, it drives the other first link 41 to move synchronously.

[0083] In this embodiment, the synchronous linkage structure includes an intermediate sliding sleeve 43 arranged vertically on the support frame 3, and a pair of synchronous sliding sleeves 44 rotatably installed on opposite sides of the intermediate sliding sleeve 43. The pair of synchronous sliding sleeves 44 are slidably arranged with the two first connecting rods 41 respectively, and the pair of synchronous sliding sleeves 44 are respectively arranged on the inner and outer sides of the support frame 3.

[0084] The rotating shaft rotatably connected to the intermediate sliding sleeve 43 and a pair of synchronous sliding sleeves 44 is designated as the synchronous shaft 900. Exemplarily, the synchronous shaft 900 and the preset rotating shaft 100 are always coplanar and located in the same vertical plane. The synchronous shaft 900 extends along the X direction, and the support frame 3 is provided with an elongated hole. The synchronous shaft 900 movably passes through the elongated hole in the vertical direction, and both ends of the synchronous shaft 900 rotatably pass through the intermediate sliding sleeve 43 and are respectively rotatably connected to the two synchronous sliding sleeves 44.

[0085] For ease of description, the two enclosures 1 are designated as first enclosure 1a and second enclosure 1b, the two first connecting rods 41 are designated as first connecting rod one 41a and first connecting rod two 41b, and the two second connecting rods 42 are designated as second connecting rod one 42a and second connecting rod two 42b. Specifically, the first enclosure 1a, first connecting rod one 41a, and second connecting rod one 42a are correspondingly arranged, as are the second enclosure 1b, first connecting rod two 41b, and second connecting rod two 42b.

[0086] Taking the support frame 3 as an example, when it is necessary to switch the vehicle from the unfolded state to the folded state, a downward external force is applied to the first frame 1a, causing the first frame 1a to rotate downward around the preset pivot 100, and the first frame 1a gradually approaches the support frame 3.

[0087] Simultaneously, as the first frame 1a rotates downward around the preset pivot 100, the second pivot 300 corresponding to the first frame 1a rotates circumferentially around the preset pivot 100, causing the second pivot 300 to be pulled upward. The folding process of the support frame 2, which is located on the same side of the support frame 3 as the first frame 1a, is as follows:

[0088] The first connecting rod 41a, corresponding to the first frame 1a, is pulled upward along with the second pivot shaft 300. The first connecting rod 41a pulls the first bearing plate 21 to rotate upward around the second pivot shaft 300. At the same time, the first connecting rod 41a pulls the second connecting rod 42a. Under the combined action of the first connecting rod 41a and the first bearing plate 21, the second connecting rod 42a rotates upward around the fourth pivot shaft 500. Meanwhile, the second bearing plate 22 rotates downward around the bearing pivot shaft 700 under the combined action of the second connecting rod 42a and the second bearing plate 22, thereby folding the first frame 1a and the first bearing plate 21 between the support frame 3 and the second bearing plate 22.

[0089] During the upward lifting of the first connecting rod 41a, the folding process of the second frame 1b and the bearing frame 2 located on the same side of the support frame 3 as the second frame 1b is as follows:

[0090] The synchronous sliding sleeve 44 on the first connecting rod 41a slides downward along its extension direction. This synchronous sliding sleeve 44 will drive the intermediate sliding sleeve 43 to slide downward, thereby causing the intermediate sliding sleeve 43 to drive another synchronous sliding sleeve 44 to slide downward along the extension direction of the second connecting rod 41b. This pushes the second connecting rod 41b upward, and the second pivot shaft 300 corresponding to the second connecting rod 41b will rotate around the preset rotating shaft 100, causing the second frame 1b to rotate downward around the preset rotating shaft 100. The second frame 1b then supports... The support frame 3 moves closer together; at the same time, the first connecting rod 41b will pull the first bearing plate 21 to rotate upward around the first pivot axis 200, and the second connecting rod 42b will rotate upward around the fourth pivot axis 500 under the combined action of the first connecting rod 41b and the first bearing plate 21. The second bearing plate 22 will rotate downward around the bearing pivot axis 700 under the combined action of the second connecting rod 42b and the first bearing plate 21, so that the second frame 1b and the first bearing plate 21 are folded between the support frame 3 and the second bearing plate 22.

[0091] Ultimately, the vehicle can switch from an unfolded state to a folded state.

[0092] Furthermore, by placing a pair of synchronous sliding sleeves 44 on the inner and outer sides of the support frame 3 respectively, interference between the two first connecting rods 41 can be avoided. Specifically, the two second connecting rods 42 are both arranged along the X direction between the support frame 3 and the bearing frame 2. The first connecting rod 41 corresponding to the synchronous sliding sleeve 44 located on the outer side of the support frame 3 is set as a bent rod, so that one end of the first connecting rod 41 connecting to the synchronous sliding sleeve 44 on the outer side of the support frame 3 is located on the outer side of the synchronous sliding sleeve 44, and the other side is bent to the inner side of the support frame 3.

[0093] Furthermore, the support frame 3 is provided with an unfolding limiting wall and a folding limiting wall spaced apart along the Z direction. The unfolding limiting wall is closer to the first axis along the Z direction than the folding limiting wall. When the vehicle is in the unfolded state, the synchronous shaft 900 abuts against the unfolding limiting wall. When the vehicle is in the folded state, the synchronous shaft 900 abuts against the folding limiting wall.

[0094] The synchronous shaft 900's movement along the Z-direction is limited by the unfolding and folding limiting walls. When the vehicle is switched from the unfolded state to the folded state, the synchronous shaft 900 will be unable to move further when it comes into contact with the folding limiting wall, indicating that the vehicle has been switched to the folded state, thus serving as a notification to the user that the vehicle has been switched to the folded state. Similarly, when the vehicle is switched from the folded state to the unfolded state, the synchronous shaft 900 will be unable to move further when it comes into contact with the unfolding limiting wall, indicating that the vehicle has been switched to the unfolded state, thus serving as a notification to the user that the vehicle has been switched to the unfolded state.

[0095] In this embodiment, the elongated hole has two inner sidewalls arranged opposite each other in the vertical direction. The upper inner sidewall of the elongated hole forms the aforementioned unfolding limiting wall, and the lower inner sidewall of the elongated hole forms the aforementioned folding limiting wall. It should be noted that the unfolding limiting wall and the folding limiting wall are not limited to the above structure, and other structures can also be used, such as setting limiting protrusions on the support frame 3, etc., which will not be described in detail here.

[0096] Furthermore, there are two linkage mechanisms 4, and the support frame 2 is positioned between the two linkage mechanisms 4. Specifically, the two linkage mechanisms 4 are spaced apart along the X-direction, and the support frame 2 is positioned between the two linkage mechanisms 4 along the X-direction.

[0097] Two support frames 3 are provided, and the carrier frame 2 is positioned between the two support frames 3. Specifically, the two support frames 3 are spaced apart along the X-direction, and the carrier frame 2 is positioned between the two support frames 3 along the X-direction. When the carrier is folded or unfolded, the support frames 3 remain stationary, and the two support frames 3 provide stable support for the two carrier frames 2.

[0098] like Figure 1 As shown, in this embodiment, the support frame 3 includes an upright 31 extending along the Z direction and a horizontal bar 32 disposed below the upright 31. The horizontal bar 32 extends along the Y direction, and the upright 31 and the corresponding horizontal bar 32 are connected to form an inverted T-shaped bar. The enclosure 1 and the bearing frame 2 are disposed on one side of the upright 31 in the Y direction, and the enclosure bar 12 is a U-shaped bar. Each of the two open ends of the U-shaped bar is connected to an adapter 11. The two adapters 11 located on the same side in the X direction are rotatably connected to the upper end of the upright 31 on the same side through a preset rotating shaft 100. The two preset rotating shafts 100 arranged at intervals in the X direction are coaxial. The two ends of the horizontal bar 32 are rotatably connected to two first bearing plates 21 through a first pivot shaft 200.

[0099] Furthermore, such as Figure 9 As shown, the support frame 3 is connected to the bracket 5. When the carrier is used for assembling a structure such as a trolley, it is connected to the trolley frame via the bracket 5. The bracket 5 does not participate in the unfolding and folding process of the entire carrier.

[0100] Specifically, there are two brackets 5, with one bracket 5 mounted on each of the two support frames 3 spaced apart along the X direction, and the two support frames 3 positioned between the two brackets 5 along the X direction. It should be noted that the brackets 5 and the support frames 3 can be connected by snap-fit ​​or by fasteners, which is not specifically limited here. In other embodiments, the brackets 5 can also be fixed to the frame 1.

[0101] Furthermore, the vehicle also includes a cloth sleeve supported between the enclosure 1 and the support frame 2; in the unfolded state, the support frame 2, the cloth sleeve and the enclosure 1 form a support space with an upward opening.

[0102] It should be noted that when the vehicle is in the unfolded state, the cover is stretched. When folding the vehicle, the cover itself can be folded freely, which will not affect the folding of the vehicle.

[0103] Furthermore, the vehicle also includes a locking unit, which can fix the two support frames 2 relative to each other when the vehicle is in the folded state, keeping the vehicle in the folded state; the locking unit can also unlock the two support frames 2, allowing the vehicle to switch from the folded state to the unfolded state. The locking unit can be a magnetic structure, a pin structure, or a strap structure, etc., which will not be described in detail here.

[0104] In other embodiments, the locking unit can also fix the two frames 1 relative to each other when the vehicle is in a folded state, and unlock the two frames 1 so that the vehicle can switch from a folded state to an unfolded state; the locking unit can also fix the two first links 41 located at the same end in the X direction relative to each other, and unlock the two first links 41 located at the same end in the X direction so that the vehicle can switch from a folded state to an unfolded state.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
