In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0043] The embodiment of the present application provides a carrier such as a folding sleeping basket, etc., which has a folded state and an unfolded state. By the carrier of the present embodiment, not only can the carrier be switched between the unfolded state and the folded state, but also the folding and unfolding processes of the carrier can be simplified, and the user experience can be improved. The present embodiment takes the folding sleeping basket as an example to specifically introduce the carrier.

[0044] It should be noted that in the following, the vertical direction represents the Z direction in the figure, the X direction in the figure represents the width direction of the folding sleeping basket, and the Y direction in the figure represents the length direction of the folding sleeping basket. The X direction, the Y direction and the Z direction are perpendicular to each other.

[0045] As shown in Figure 1 and Figure 2 , the carrier includes a surrounding frame 1, a bearing frame 2, a support frame 3 and a linkage mechanism 4, wherein the surrounding frame 1 and the bearing frame 2 are arranged on the same side of the support frame 3, and the surrounding frame 1 and the bearing frame 2 are respectively rotationally arranged on the support frame 3; the bearing frame 2 is foldable, the linkage mechanism 4 is arranged between the surrounding frame 1 and the bearing frame 2, and when the surrounding frame 1 is moved towards the support frame 3, the bearing frame 2 is folded by the linkage mechanism 4 and is moved towards the support frame 3 to switch the carrier from the unfolded state to the folded state.

[0046] As shown in Figures 3 to 6 , when the carrier is switched from the unfolded state to the folded state, the surrounding frame 1 is moved towards the support frame 3, the linkage mechanism 4 drives the bearing frame 2 to fold and move towards the support frame 3, and the action of the surrounding frame 1 drives the action of the bearing frame 2 through the linkage mechanism 4. Compared with the independent action of the surrounding frame 1 and the bearing frame 2 in the prior art, the folding of the carrier is relatively simple, and the user experience can be greatly improved.

[0047] Further, as shown in Figure 1 , Figures 3 to 6 , the bearing frame 2 includes a first bearing plate 21 and a second bearing plate 22 arranged opposite to each other, the first bearing plate 21 is rotationally installed on the support frame 3, and when the surrounding frame 1 is moved towards the support frame 3, the linkage mechanism 4 drives the first bearing plate 21 to move towards the support frame 3 and the second bearing plate 22 to move towards the first bearing plate 21.

[0048] In the embodiment, the linkage mechanism 4 comprises a first connecting rod 41 and a second connecting rod 42, the first connecting rod 41 is movably connected with the surrounding frame 1 and the first bearing plate 21 respectively, and the second connecting rod 42 is movably connected with the first connecting rod 41 and the second bearing plate 22 respectively.

[0049] Specifically, the surrounding frame 1 and the bearing frame 2 are arranged on the same side of the support frame 3 in the Y direction, the surrounding frame 1 is arranged on the upper side of the bearing frame 2 when the carrier is in the unfolded state, the bearing surface of the first bearing plate 21 and the bearing surface of the second bearing plate 22 are both upward when the carrier is in the unfolded state, and the two bearing surfaces are used for bearing together, the bearing area is large, and the bearing demand of the user can be met.

[0050] Exemplarily, the bearing surface of the first bearing plate 21 and the bearing surface of the second bearing plate 22 are in the same horizontal plane when the carrier is in the unfolded state, and the concave-convex bearing surface can avoid affecting the user experience when the carrier is used as a folding sleeping basket.

[0051] When the surrounding frame 1 is flipped downward to approach the support frame 3, the first bearing plate 21 is flipped upward to approach the support frame 3, and the second bearing plate 22 is flipped downward to approach the first bearing plate 21; the bearing surface of the first bearing plate 21 and the bearing surface of the second bearing plate 22 are arranged oppositely when the carrier is in the folded state.

[0052] The bearing surface of the first bearing plate 21 and the bearing surface of the second bearing plate 22 are arranged oppositely when the carrier is in the folded state, so that the first bearing plate 21 is folded between the second bearing plate 22 and the support frame 3, and the occupied space of the carrier after folding is reduced.

[0053] It should be noted that the first bearing plate 21 and the second bearing plate 22 are both in the form of a flat plate, and can also be in the form of a structure surrounded by multiple rods and can be hollow.

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

[0055] In the embodiment, as Figure 1 , Figures 3 to 6As shown, the enclosure 1 comprises an enclosure rod 12 and a connector 11 arranged on the enclosure rod 12, the connector 11 is rotatably arranged on the support frame 3 through a preset rotation shaft 100, the first connecting rod 41 is pivotally connected to the connector 11, and the pivot connection position of the first connecting rod 41 and the connector 11 is arranged on the two sides of the preset rotation shaft 100 opposite to the enclosure rod 12, so that when the enclosure rod 12 approaches the support frame 3, the first connecting rod 41 is driven to rotate upward to pull the first bearing plate 21 upward.

[0056] Specifically, the preset rotation shaft 100 extends along the X direction, the first connecting rod 41 is pivotally connected to the connector 11, the pivot shaft of the first connecting rod 41 and the connector 11 is referred to as a second pivot shaft 300, the second pivot shaft 300 extends along the X direction, and the enclosure rod 12 and the second pivot shaft 300 are located on opposite sides of a preset plane 800, wherein the second pivot shaft 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 shaft 300 and the enclosure rod 12 are arranged on the two sides of the preset rotation shaft 100 in the Y direction.

[0057] For ease of understanding, the pivot connection position of the first connecting rod 41 and the connector 11 in the folded state of the carrier is referred to as a folded pivot connection position, and the pivot connection position of the first connecting rod 41 and the connector 11 in the unfolded state of the carrier is referred to as an unfolded pivot connection position. The folded pivot connection position and the unfolded pivot connection position are always located on the same side of the support frame 3 in the Y direction, regardless of the unfolded state or the folded state, the enclosure rod 12 is always located on the other side of the support frame 3 in the Y direction.

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

[0059] Further, as shown in Figure 1 and Figure 3 When the carrier is in the unfolded state, in the vertical direction, the pivot connection position of the first connecting rod 41 and the connector 11 is arranged on the lower side of the preset rotation shaft 100. In other words, when the carrier is in the unfolded state, the second pivot shaft 300 is located below the preset rotation shaft 100, and because the second pivot shaft 300 and the enclosure rod 12 are arranged on the two sides of the preset rotation shaft 100 in the Y direction, when the enclosure rod 12 rotates downward to approach and fold the support frame 3, the first connecting rod 41 rotates upward to pull the first bearing plate 21.

[0060] As shown in Figure 6 When the carrier is in the folded state, in the vertical direction, the pivot connection position of the first connecting rod 41 and the connector 11 is on the upper side of the preset rotation shaft 100. In other words, when the carrier is in the folded state, the second pivot shaft 300 is located above the preset rotation shaft 100.

[0061] As shown in Figures 3 to 6As shown, during the process that the carrier switches from the unfolded state to the folded state, the acute angle between the first connecting rod 41 and the support frame 3 is first gradually increased, and when the central axis of the preset rotating shaft 100 and the central axis of the second pivot shaft 300 are horizontally coplanar, the acute angle between the first connecting rod 41 and the support frame 3 is maximum; with the continuous lifting of the height of the second pivot shaft 300, the acute angle between the first connecting rod 41 and the support frame 3 is gradually reduced, which is beneficial to improve the width of the entire carrier along the Y direction after the carrier is folded, thereby reducing the occupied space of the carrier after folding.

[0062] Further, as shown in Figure 1 、 Figures 3 to 6 , the second connecting rod 42 is pivoted on the first connecting rod 41, and the first bearing plate 21 and the second bearing plate 22 are pivoted on the bearing pivot shaft 700; in the unfolded state of the carrier, part of the second bearing plate 22 is extended and arranged on one side of the bearing pivot shaft 700 close to the first bearing plate 21 to form a first extension 221, and one end of the second connecting rod 42 away from the first connecting rod 41 is pivoted on the first extension 221.

[0063] Specifically, the side of the first bearing plate 21 connected to the second bearing plate 22 is provided with a second extension 213, the second extension 213 is arranged between the two first extensions 221, and the second extension 213 is pivoted on the two first extensions 221 through the bearing pivot shaft 700. The outer first extension 221 is pivoted on the second connecting rod 42 through the fifth pivot shaft 600.

[0064] Exemplarily, the second extension 213 is mounted on the first bearing plate 21 through a fastener, and the first extension 221 is mounted on the second bearing plate 22 through a fastener. In other embodiments, the first bearing plate 21 and the second extension 213 can also be integrally formed, and the first extension 221 and the second bearing plate 22 can also be integrally formed.

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

[0066] No matter whether the carrier is in the unfolded state or the folded state, the bearing pivot shaft 700 is always located below the fifth pivot shaft 600 along the vertical direction. In the unfolded state of the carrier, the fifth pivot shaft 600 is closer to the support frame 3 than the bearing pivot shaft 700 along the Y direction; in the folded state of the carrier, the bearing pivot shaft 700 is closer to the support frame 3 than the fifth pivot shaft 600 along the Y direction.

[0067] The fourth pivot shaft 500 is located between the third pivot shaft 400 and the second pivot shaft 300 along the extending direction of the first connecting rod 41, and the third pivot shaft 400 is closer to the fourth pivot shaft 500 than the second pivot shaft 300.

[0068] When the first connecting rod 41 rotates upward to lift the first bearing plate 21, the second connecting rod 42 rotates upward around the fourth pivot shaft 500 under the joint action of the first connecting rod 41 and the first bearing plate 21, so that the second bearing plate 22 rotates downward around the bearing pivot shaft 700 under the joint action of the first bearing plate 21 and the second connecting rod 42, thereby making the bearing surface of the first bearing plate 21 and the bearing surface of the second bearing plate 22 face away from each other, so as to fold the first bearing plate 21 along the Y direction between the support frame 3 and the second bearing plate 22.

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

[0070] Specifically, in order to facilitate understanding, the pivot shaft of the first bearing plate 21 and the support frame 3 is referred to as the first pivot shaft 200, and the pivot shaft of the first connecting rod 41 and the first bearing plate 21 is referred to as the third pivot shaft 400, both of which extend along the X direction. The first pivot shaft 200 is arranged at the first connecting end 211 of the first bearing plate 21, the bearing pivot shaft 700 pivotally connecting the second bearing plate 22 and the first bearing plate 21 is arranged at the second connecting end 212 of the first bearing plate 21, the third pivot shaft 400 is arranged between the bearing pivot shaft 700 and the first pivot shaft 200, and the first pivot shaft 200 is closer to the third pivot shaft 400 than the bearing pivot shaft 700.

[0071] Arranging the first connecting end 211 to be closer to the pivot position of the first connecting rod 41 and the first bearing plate 21 than the second connecting end 212 can reduce the rotation amplitude of the first connecting rod 41 when the first connecting rod 41 rotates upward to lift the first bearing plate 21, reduce the center distance between the second pivot shaft 300 and the preset pivot shaft 100, thereby reducing the size of the adapter 11; it is also beneficial for 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] Further, as shown in Figure 1As shown, the pair of surrounding frames 1 are oppositely rotatably fixed on the opposite sides of the support frame 3. The pair of bearing frames 2 are oppositely rotatably fixed on the opposite sides of the support frame 3.

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

[0074] By arranging the two surrounding frames 1 and the two bearing frames 2, the bearing area formed by the bearing surfaces of the two first bearing plates 21 and the bearing surfaces of the two second bearing plates 22 when the carrier is in the unfolded state can be increased to meet the user's needs. Moreover, the two bearing frames 2 are arranged on the two sides of the support frame 3, which can improve the stability of the carrier along the Y direction when the carrier is in the unfolded state.

[0075] Exemplarily, the structures on the two sides of the support frame 3, such as the bearing frame 2, the linkage mechanism 4 and the surrounding frame 1, are arranged in rotational symmetry, specifically, the bearing frame 2, the linkage mechanism 4 and the surrounding frame 1 on either side of the support frame 3 can be obtained by rotating the bearing frame 2, the linkage mechanism 4 and the surrounding frame 1 on the other side of the support frame 3 by 180°.

[0076] When the carrier is in the unfolded state, the bearing pivot shaft 700, the fifth pivot shaft 600, the third pivot shaft 400 and the first pivot shaft 200 are all arranged 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 the pivot shafts affecting the use of the bearing surface.

[0077] Further, as shown in Figure 3 , Figure 6 and Figure 7 , the adapter 11 is provided with a clearance portion, the clearance portion has an unfolding limiting surface 1111 and a folding limiting surface 1112, and the first connecting rod 41 is limited between the unfolding limiting surface 1111 and the folding limiting surface 1112; when the carrier is in the unfolded state, the first connecting rod 41 abuts against the unfolding limiting surface 1111; when the carrier is in the folded state, the first connecting rod 41 abuts against the folding limiting surface 1112. In this way, the position of the first connecting rod 41 when the carrier is unfolded and folded can be limited.

[0078] In the embodiment, the avoiding part is an avoiding groove 111 arranged on the adapter 11, and the unfolding limiting surface 1111 and the folding limiting surface 1112 are inner walls of the avoiding groove 111. Exemplarily, the adapter 11 is in a discoid structure, the axial direction of the discoid structure is the X direction, the avoiding groove 111 is arranged on the axial end surface of the adapter 11, one side of the avoiding groove 111 extends to the outer circumferential wall of the adapter 11 along the radial direction of the adapter 11, the unfolding limiting surface 1111 is a plane, the folding limiting surface 1112 is an arc surface, the first connecting rod 41 is provided with the unfolding cooperation surface 411 and the folding cooperation surface 412, and the folding cooperation surface 412 is arranged on the end of the first connecting rod 41. When the carrier is in the unfolded state, the unfolding cooperation surface 411 abuts against the unfolding limiting surface 1111; when the carrier is in the folded state, the folding limiting surface 1112 abuts against the folding cooperation surface 412.

[0079] Further, as shown in Figure 1 two first bearing plates 21 are arranged along the Y direction, so that interference between the two bearing frames 2 can be avoided when the carrier is folded, and space is provided for rotation of the two first bearing plates 21.

[0080] Further, the two surrounding frames 1 are connected with the two bearing frames 2 through the linkage mechanism 4, and when any surrounding frame 1 moves towards the support frame 3 to be folded, the surrounding frame 1 can drive the two bearing frames 2 and the other surrounding frame 1 to move towards the support frame 3 to be folded through the linkage mechanism 4, so as to switch the carrier from the unfolded state to the folded state.

[0081] The carrier connects the two surrounding frames 1 with the two bearing frames 2 through the linkage mechanism 4, so that when any surrounding frame 1 moves towards the support frame 3 to be folded, the surrounding frame 1 can drive the two first bearing frames 2 to move towards the support frame 3 to be folded through the linkage mechanism 4, and the other surrounding frame 1 is also driven by the linkage mechanism 4 to move towards the support frame 3 to be folded, so that one surrounding frame 1 drives the other surrounding frame 1 and the two bearing frames 2 to move when the one surrounding frame 1 moves. Compared with the prior art, the folding of the carrier is relatively simple, and the user experience can be greatly improved.

[0082] Further, the linkage mechanism 4 includes two first connecting rods 41 and two second connecting rods 42, the two first connecting rods 41 and the two second connecting rods 42 are arranged in one-to-one correspondence, the two first connecting rods 41 are arranged in one-to-one correspondence with the two bearing frames 2 and the two surrounding frames 1, and the linkage mechanism 4 further includes a synchronous linkage structure for controlling linkage of the two first connecting rods 41, and the synchronous linkage structure is slidably connected with the two first connecting rods 41 respectively, so as to drive the other first connecting rod 41 to move synchronously when any first connecting rod 41 moves.

[0083] In the embodiment, the synchronous linkage structure comprises a middle sliding sleeve 43 arranged on the support frame 3 in the vertical direction, and a pair of synchronous sliding sleeves 44 rotatably arranged on opposite sides of the middle sliding sleeve 43, the pair of synchronous sliding sleeves 44 are respectively arranged on the inner and outer sides of the support frame 3.

[0084] The rotation shaft connecting the middle sliding sleeve 43 and the pair of synchronous sliding sleeves 44 is referred to as a synchronous shaft 900, and the synchronous shaft 900 and the preset rotation shaft 100 are always coplanar and located in the same vertical plane. The synchronous shaft 900 extends along the X direction, and a long hole is arranged on the support frame 3, the synchronous shaft 900 is movably penetrated through the long hole in the vertical direction, and the two ends of the synchronous shaft 900 are rotatably penetrated out of the middle sliding sleeve 43 and are respectively rotatably connected to the two synchronous sliding sleeves 44.

[0085] For the convenience of description, the two surrounding frames 1 are respectively referred to as a first surrounding frame 1a and a second surrounding frame 1b, the two first connecting rods 41 are respectively referred to as a first connecting rod one 41a and a first connecting rod two 41b, and the two second connecting rods 42 are respectively referred to as a second connecting rod one 42a and a second connecting rod two 42b. Among them, the first surrounding frame 1a, the first connecting rod one 41a and the second connecting rod one 42a are correspondingly arranged, and the second surrounding frame 1b, the first connecting rod two 41b and the second connecting rod two 42b are correspondingly arranged.

[0086] Taking the support frame 3 as an example, when it is necessary to switch the carrier from the unfolded state to the folded state, an external force is applied to the first surrounding frame 1a in the downward direction, so that the first surrounding frame 1a rotates downward around the preset rotation shaft 100, and the first surrounding frame 1a gradually approaches the support frame 3;

[0087] At the same time, in the process of rotating the first surrounding frame 1a around the preset rotation shaft 100 in the downward direction, the second pivot shaft 300 corresponding to the first surrounding frame 1a rotates around the preset rotation shaft 100 in the circumferential direction, so that the second pivot shaft 300 is pulled upward, and the folding process of the carrier frame 2 located on the same side of the first surrounding frame 1a with the support frame 3 is as follows:

[0088] The first connecting rod one 41a corresponding to the first surrounding frame 1a is pulled upward with the second pivot shaft 300, the first connecting rod one 41a pulls the first carrier plate 21 to rotate upward around the second pivot shaft 300, and the first connecting rod one 41a pulls the second connecting rod one 42a, under the joint action of the first connecting rod one 41a and the first carrier plate 21, the second connecting rod one 42a rotates upward around the fourth pivot shaft 500, and the second carrier plate 22 rotates downward around the carrier pivot shaft 700 under the joint action of the second connecting rod one 42a and the second carrier plate 22, so that the first surrounding frame 1a and the first carrier plate 21 are folded between the support frame 3 and the second carrier plate 22;

[0089] In the process of pulling up the first link 41a, the folding process of the second frame 1b and the carrier frame 2 on the same side of the second frame 1b is as follows:

[0090] The synchronization sleeve 44 on the first link 41a slides downward along the extension direction thereof, which drives the middle sleeve 43 to slide downward, so that the middle sleeve 43 drives the other synchronization sleeve 44 to slide downward along the extension direction of the second link 41b, and the first link 41b is pushed to be pulled up, the second pivot shaft 300 corresponding to the first link 41b rotates around the preset pivot shaft 100, so that the second frame 1b rotates downward around the preset pivot shaft 100, and the second frame 1b approaches the support frame 3; at the same time, the first link 41b pulls the first carrier plate 21 to rotate upward around the first pivot shaft 200, and the second link 42b rotates upward around the fourth pivot shaft 500 under the joint action of the first link 41b and the first carrier plate 21, and the second carrier plate 22 rotates downward around the carrier pivot shaft 700 under the joint action of the second link 42b and the first carrier plate 21, so that the second frame 1b and the first carrier plate 21 are folded between the support frame 3 and the second carrier plate 22;

[0091] Finally, the carrier is switched from the unfolded state to the folded state.

[0092] In addition, the pair of synchronization sleeves 44 are arranged on the inner and outer sides of the support frame 3, which can also avoid the interference of the two first links 41. Specifically, the two second links 42 are arranged between the support frame 3 and the carrier frame 2 along the X direction, and the first link 41 corresponding to the synchronization sleeve 44 arranged on the outer side of the support frame 3 is arranged as a bent link, so that one end of the first link 41 connected to the synchronization sleeve 44 on the outer side of the support frame 3 is located on the outer side of the synchronization sleeve 44, and the other end is bent to the inner side of the support frame 3.

[0093] Further, the support frame 3 is provided with an unfolding limiting wall and a folding limiting wall arranged along the Z direction, and the unfolding limiting wall is closer to the first axis than the folding limiting wall along the Z direction; when the carrier is in the unfolded state, the synchronization shaft 900 abuts against the unfolding limiting wall; when the carrier is in the folded state, the synchronization shaft 900 abuts against the folding limiting wall.

[0094] The upper and lower two limit positions of the Z-direction movement of the synchronous shaft 900 are limited by the unfolded limiting wall and the folded limiting wall. When the synchronous shaft 900 abuts against the folded limiting wall during the switching of the carrier from the unfolded state to the folded state, the synchronous shaft 900 cannot continue to move, which indicates that the carrier has been switched to the folded state, and can prompt the user that the carrier has been switched to the folded state. When the synchronous shaft 900 abuts against the unfolded limiting wall during the switching of the carrier from the folded state to the unfolded state, the synchronous shaft 900 cannot continue to move, which indicates that the carrier has been switched to the unfolded state, and can prompt the user that the carrier has been switched to the unfolded state.

[0095] In the embodiment, the long hole has two inner side walls oppositely arranged in the vertical direction. The upper inner side wall of the long hole forms the unfolded limiting wall, and the lower inner side wall of the long hole forms the folded limiting wall. It should be noted that the unfolded limiting wall and the folded limiting wall are not limited to the above structure, and other structures can also be used, such as a limiting protrusion arranged on the support frame 3, which will not be described in detail here.

[0096] Further, the linkage mechanism 4 is provided with two, and the carrier frame 2 is arranged between the two linkage mechanisms 4. Specifically, the two linkage mechanisms 4 are arranged at intervals along the X direction, and the carrier frame 2 is arranged between the two linkage mechanisms 4 along the X direction.

[0097] The support frame 3 is provided with two, and the carrier frame 2 is arranged between the two support frames 3. Specifically, the two support frames 3 are arranged at intervals along the X direction, and the carrier frame 2 is arranged between the two support frames 3 along the X direction. When the carrier is folded and unfolded, the support frame 3 is stationary, and the two support frames 3 provide stable support for the two carrier frames 2.

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

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

[0100] Specifically, the carrier 5 is provided with two, two support frames 3 are arranged along the X direction and are spaced apart from each other, and one carrier 5 is arranged on each support frame 3. The two support frames 3 are arranged along the X direction between the two carriers 5. It should be noted that the carrier 5 and the support frame 3 can be connected by clamping or by fasteners, and are not specifically limited here. In other embodiments, the carrier 5 can also be fixed to the surrounding frame 1.

[0101] Further, the carrier further comprises a cloth cover supported between the surrounding frame 1 and the carrier frame 2; in the unfolded state, the carrier frame 2, the cloth cover and the surrounding frame 1 form a carrier space arranged with an upward opening.

[0102] It should be noted that when the carrier is in the unfolded state, the cloth cover is tensioned, and when the carrier is folded, the cloth cover itself can be folded at will and will not affect the folding of the carrier.

[0103] Further, the carrier further comprises a locking unit, the locking unit can relatively fix the two carrier frames 2 when the carrier is in the folded state, so that the carrier remains in the folded state; the locking unit can also unlock the two carrier frames 2, so that the carrier can be switched from the folded state to the unfolded state. The locking unit can be a magnetic structure, or a latch structure, or a strap structure, and will not be described here.

[0104] In other embodiments, the locking unit can also relatively fix the two surrounding frames 1 when the carrier is in the folded state, and unlock the two surrounding frames 1, so that the carrier can be switched from the folded state to the unfolded state; the locking unit can also relatively fix the two first connecting rods 41 located at the same end along the X direction, and unlock the two first connecting rods 41 located at the same end along the X direction, so that the carrier can be switched from the folded state to the unfolded state.
