Description

Technical Field

[0001] This utility model relates to the field of children's products technology, and in particular to a bassinet and stroller. Background Technology

[0002] Currently, most strollers have a folding function so that they can be folded and stored when not in use, reducing the space occupied by the stroller. However, the folding process of most existing strollers is usually quite cumbersome, making it difficult for users to operate during the folding process, resulting in a poor user experience. Utility Model Content

[0003] The main purpose of this invention is to propose a bassinet and stroller that aims to alleviate the problem of the cumbersome folding process of current children's strollers.

[0004] On the one hand, the trolley proposed by this utility model includes a frame and a load-bearing component. The frame includes two supports distributed in the front-rear direction. The two supports include a first support and a second support. The ends of the first support and the second support that are close to each other are rotatably connected. The first support and the second support can rotate to move closer and further away from each other to be in a first folded state and a first unfolded state, respectively.

[0005] The carrier includes:

[0006] A frame, mounted on the vehicle frame, comprises two interlocking and rotatably connected semi-frames. The two semi-frames include a first semi-frame corresponding to the first bracket and a second semi-frame corresponding to the second bracket. The first and second semi-frames are rotatable towards and away from each other to correspond to a second folded state and a second unfolded state.

[0007] A support assembly is driven between the bracket and the half-frame, such that when the two brackets are in a first folded state, the two half-frames are moved to a second folded state through the support assembly, and when the two brackets are in a first unfolded state, the two half-frames are moved to a second unfolded state through the support assembly.

[0008] In some embodiments, the support assembly includes a linkage mechanism that is driven between the bracket and the half-frame.

[0022] At least one of the mounting bases is a mounting shaft, and the fixing part corresponding to the mounting shaft is a snap-fit ​​groove, wherein the mounting shaft is snapped into and rotatably connected to the snap-fit ​​groove.

[0023] In some embodiments, the first mounting part is a mounting shaft, and the fixing part of the first connecting rod is a snap-fit ​​groove.

[0024] The frame also includes an armrest and a third link. The armrest is connected to the second bracket, and the third link is connected to both the armrest and the first bracket.

[0025] The third link is rotatably connected to the first bracket via the mounting shaft.

[0026] In some embodiments, the frame further includes a third mounting portion, and a third fixing portion is provided on the frame, the third fixing portion being detachably connected to the third mounting portion; and / or,

[0027] The frame also includes a third mounting part, and the trolley also includes a seat, wherein at least one of the first mounting part, the second mounting part, and the third mounting part is detachably mounted to the seat.

[0028] On the other hand, the sleeping basket provided by this utility model includes:

[0029] The fence comprises two interlocking and rotatably connected semi-frames, the two semi-frames being able to rotate closer and further apart to correspond to a second folded state and a second unfolded state; and,

[0030] The support assembly includes a first link and a second link, one end of which is connected to the corresponding half-frame, and the other end of each of the first link and the second link has a fixing part, which is configured to be detachably connected to the corresponding bracket of the frame.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0055] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0056] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0057] Currently, folding functionality has become a standard feature in the design of children's strollers. When not in use, users can fold the stroller to store it, thus alleviating the pain point of limited space in urban families. However, the folding process of most existing children's strollers is usually quite cumbersome, making it difficult for users to operate during the folding process, resulting in a poor user experience.

[0058] The reason for this is that most strollers consist of a frame and a side rail, and both the frame and side rail can be folded to meet the folding requirements of the stroller. However, the folding process of the frame and side rail in current strollers is usually not directly related. That is, the folding process of these two components needs to be carried out in steps, so users need to operate at least both sides to fully fold the stroller.

[0059] In view of this, the present invention provides a stroller that reduces the user's folding steps by linking the folding process of the frame and the stroller body together, aiming to alleviate the problem of the cumbersome folding process of current children's strollers.

[0061] Firstly, please refer to Figure 5 and Figure 7 In one embodiment of this utility model, the trolley 100 includes a frame 1 and a support member 10. The frame 1 includes two supports 1a distributed in the front-rear direction. The two supports 1a include a first support 11 and a second support 12. The ends of the first support 11 and the second support 12 that are close to each other are rotatably connected. The first support 11 and the second support 12 can rotate closer to each other and further away from each other to correspond to a first folded state and a first unfolded state. The support member 10 includes a frame 2 and a support component 3. The frame 2 is installed on the frame 1. The frame 2 includes two half-frames 2a that are spliced ​​together and rotatably connected. The two half-frames 2a enclose... The first half-frame 21 corresponds to the first bracket 11, and the second half-frame 22 corresponds to the second bracket 12. The first half-frame 21 and the second half-frame 22 can rotate to move closer to each other and further away from each other to be in a second folded state and a second unfolded state, respectively. The support component 3 is drivenly connected between the bracket 1a and the half-frame 2a, so that when the two brackets 1a are in the first folded state, the two half-frames 2a are moved to the second folded state through the linkage of the support component 3, and when the two brackets 1a are in the first unfolded state, the two half-frames 2a are moved to the second unfolded state through the linkage of the support component 3.

[0062] Since the first support 11 and the second support 12 are two supports 1a distributed in the front-rear direction, and the ends of the first support 11 and the second support 12 that are close to each other are rotatably connected, it can be understood that the first support 11 and the second support 12 are set at an angle. As the first support 11 and the second support 12 rotate closer and further away from each other, the angle decreases and increases accordingly, meaning that the first support 11 and the second support 12 are in a first folded state and a first unfolded state, respectively. Similarly, the first half-frame 21 and the second half-frame 22 can also be set at an angle, and as the first half-frame 21 and the second half-frame 22 rotate closer and further away from each other, the angle decreases and increases accordingly, meaning that the first half-frame 21 and the second half-frame 22 are in a second folded state and a second unfolded state, respectively. In the second unfolded state, the angle between the first half-frame 21 and the second half-frame 22 is usually a straight angle, that is, 180°; the support assembly 3 is connected by a transmission. Between the bracket 1a and the half-frame 2a, the first folded state of the bracket 1a corresponds to the second folded state of the half-frame 2a, and the first unfolded state of the bracket 1a corresponds to the second unfolded state of the half-frame 2a. Under normal circumstances, the included angle between the first bracket 11 and the second bracket 12, and the included angle between the first half-frame 21 and the second half-frame 22, decrease and increase synchronously. For example, the first bracket 11 and the second bracket 12 are connected by the meshing of the first gear and the second gear, and the first half-frame 21 and the second half-frame 22 are connected by the meshing of the third gear and the fourth gear. With this arrangement, the mutual rotation of the first bracket 11 and the second bracket 12 can drive the mutual rotation of the first half-frame 21 and the second half-frame 22. This embodiment does not limit the transmission method of the support component 3 during the state transition process of the bracket 1a and the half-frame 2a, that is, it does not limit the specific structural form of the support component 3.

[0063] In the technical solution provided by this utility model, the two supports 1a that make up the frame 1 are rotatably connected to each other, so that the frame 1 has a first folded state and a first unfolded state. The two half-frames 2a that make up the enclosure 2 are rotatably spliced ​​together, so that the enclosure 2 has a second folded state and a second unfolded state. On this basis, by setting a support component 3 through a transmission connection between the support 1a and the half-frame 2a, the first folded state and the first unfolded state of the frame 1 are correspondingly associated with the second folded state and the second unfolded state of the enclosure 2, thereby realizing the linkage folding and linkage unfolding of the frame 1 and the enclosure 2, simplifying the folding process of the trolley 100, reducing the difficulty of operation for users, and thus improving the user experience.

[0064] In some embodiments, the support assembly 3 includes a linkage mechanism 3a that is driven between the bracket 1a and the half-frame 2a.

[0065] There are many specific structural types of "linkage mechanism 3a", which can be determined according to the actual needs of the user. This embodiment does not limit this.

[0066] In the above technical solution, the support component 3 includes a linkage mechanism 3a. The linkage mechanism 3a has a high load-bearing capacity and excellent impact resistance. When applied to the structure of the trolley 100, it can improve the design redundancy of the trolley 100 and ensure the reliability and safety of the structure. Moreover, the linkage mechanism 3a can be designed with a corresponding motion trajectory, so that the linkage process of folding and unfolding of the frame 2 and the frame 1 can be specifically set according to other structures of the trolley 100, such as avoiding structural interference.

[0067] Please see Figure 5 In some embodiments, the linkage mechanism 3a includes a first link 31, which is rotatably connected between the first bracket 11 and the first half-frame 21. The first half-frame 21 is connected to the first link 31 at a first node A. An upwardly extending support member 121a is provided on the frame 1. The upper end of the support member 121a is rotatably connected to the first half-frame 21, and the upper end of the support member 121a is located on the side of the first node A near the second half-frame 22, so that the first half-frame 21 can be folded downward around the support member 121a.

[0068] "A support member 121a extending upward is provided on the frame 1". The support member 121a can be specifically provided on the second bracket 12 or on other structural members of the frame 1. At this time, the first half frame 21 can be folded down relative to the support member 121a, that is, it can move downward and closer to the frame 1 as the bracket 1a is folded. The first bracket 11 can be located in front of the second bracket 12 or behind the second bracket 12.

[0069] In the above technical solution, the first link 31 is rotatably connected between the first bracket 11 and the first half-frame 21. Driven by the first link 31, as the first bracket 11 and the second bracket 12 move closer to each other, the first half-frame 21 can be folded downward around the support member 121a, which plays the role of the first half-frame 21 folding and unfolding in conjunction with the bracket 1a.

[0070] Please see Figure 5 In some embodiments, the linkage mechanism 3a includes a second link 32, which is rotatably connected between the second bracket 12 and the second half-frame 22.

[0071] In the above technical solution, the second link 32 is rotatably connected between the second bracket 12 and the second half-frame 22. Driven by the second link 32, as the first bracket 11 and the second bracket 12 move closer to each other, the second half-frame 22 can be folded downwards, which plays the role of the second half-frame 22 folding and unfolding in conjunction with the bracket 1a.

[0072] In some embodiments, the rotational connection nodes of the first half-frame 21 and the second half-frame 22 are the same nodes as the rotational connection nodes of the first bracket 11 and the second bracket 12. During the process of the first bracket 11 and the second bracket 12 rotating closer and further away from each other, the first connecting rod 31 and the second connecting rod 32 can respectively drive the first half-frame 21 and the second half-frame 22 to rotate closer and further away from each other.

[0073] Please see Figure 7 In some embodiments, the rotation point of the first half-frame 21 and the second half-frame 22 is the second node B, and the upper end of the support member 121a is located between the first node A and the second node B.

[0074] Since the first half-frame 21 can be folded downward around the support member 121a, it can be determined that the first half-frame 21 is rotatably connected to the support member 121a. At the same time, since the upper end of the support member 121a is located between the first node A and the second node B, it means that the second half-frame 22, the second link 32, the second bracket 12, the support member 121a, and the first half-frame 21 can form a multi-link mechanism.

[0075] In the above technical solution, the upper end of the support member 121a is positioned between the first node A and the second node B, so that the second half-frame 22, the second connecting rod 32, the second bracket 12, the support member 121a, and the first half-frame 21 can form a multi-link mechanism. During the process of the first bracket 11 and the second bracket 12 rotating closer and further away from each other, the multi-link mechanism 3a is conducive to driving the second half-frame 22 closer and further away from the second bracket 12, that is, increasing the rotation range of the second half-frame 22, so that the frame 2 is folded compactly and fully unfolded.

[0076] Please see Figure 7 In some embodiments, the end of the second bracket 12 that is hinged to the first bracket 11 extends upward to form an extension rod 121. The upper end of the extension rod 121 is hinged to the first half-frame 21, and the extension rod 121 forms a support member 121a.

[0077] It should be noted that in this embodiment, the extension rod 121 extending upward from the second bracket 12 forms a support member 121a. That is, the support member 121a is disposed on the second bracket 12, and the support member 121a, the first bracket 11, the first connecting rod 31, and the first half-frame 21 can form a four-bar linkage mechanism.

[0078] In the above technical solution, the support member 121a is set at the upper end of the second half frame 22, so that the support member 121a, the first bracket 11, the first connecting rod 31, and the first half frame 21 can form a four-bar linkage. During the process of the first bracket 11 and the second bracket 12 rotating closer and further away from each other, the four-bar linkage is conducive to driving the first half frame 21 closer and further away from the first bracket 11, that is, increasing the rotation range of the first half frame 21, so that the frame 2 is folded compactly and fully unfolded.

[0079] Please see Figure 5 and Figure 7 In some embodiments, the trolley 100 further includes a handle 4, which is rotatably connected to the upper end of the extension rod 121 so that it can rotate up and down around the upper end of the extension rod 121, and can rotate downward to be close to the frame 1 and upward to be away from the frame 1, corresponding to being in a third folded state and a third unfolded state; the handle 4 is driven to the first bracket 11 so that when the handle 4 rotates downward to the third folded state, it drives the two brackets 1a to be in the first folded state, and when it rotates upward to the third unfolded state, it drives the two brackets 1a to be in the first unfolded state.

[0080] The "transmission connection between the handrail 4 and the first support 11" can take many forms, such as gear transmission, chain transmission, belt transmission, etc., and this embodiment does not limit this to any particular type. Generally, in the third unfolded state, the handrail 4 is usually aligned with the extension direction of the second support 12, such as... Figure 4 As shown, the pushing and pulling force applied by the user to the handrail 4 can be directly transmitted to the second support 12, reducing the connection pressure at the rotation connection point between the handrail 4 and the extension rod 121.

[0081] In the above technical solution, the handle 4 is rotatably connected to the upper end of the second support 12, and has a third folded state that rotates closer to the frame 1 and a third unfolded state that rotates away from the frame 1. At the same time, the handle 4 is connected to the first support 11 through transmission. The third folded state of the handle 4 relative to the frame 1 corresponds to the first folded state of the two supports 1a, and the third unfolded state of the handle 4 relative to the frame 1 corresponds to the first unfolded state of the two supports 1a. That is, the folding of the handle 4 corresponds to the folding of the frame 1, which plays the role of quickly folding the trolley 100.

[0082] Please see Figure 5 and Figure 7 In some embodiments, a third link 7 is rotatably connected between the handrail 4 and the first support 11. In this embodiment, the third link 7, the first link 31, and the first support 11 can be rotatably connected around the same axis of rotation, reducing the number of parts. In other embodiments, the third link 7, the first link 31, and the first support 11 can also be rotatably connected around different axes of rotation.

[0083] In the above technical solution, the armrest 4 and the first support 11 are connected by a third link 7. The third link 7 has a high load-bearing capacity and excellent impact resistance. When applied to the structure of the trolley 100, it can improve the design redundancy of the trolley 100 and ensure the reliability and safety of the structure.

[0084] Please see Figures 2 to 4 In some embodiments, the carrier 10 is detachably connected to the frame 1; the frame 1 includes a first mounting part 111 and a second mounting part 122, the first mounting part 111 is disposed on the first bracket 11, and the second mounting part 122 is disposed on the second bracket 12; the support assembly 3 includes a first connecting rod 31 and a second connecting rod 32, the first connecting rod 31 is detachably connected to the first mounting part 111, and the second connecting rod 32 is detachably connected to the second mounting part 122.

[0085] It should be noted that the "detachable connection between the first connecting rod 31 and the first mounting part 111" and the "detachable connection between the second connecting rod 32 and the second mounting part 122" can be achieved by a snap-fit ​​connection structure or by a bolt connection structure. This embodiment does not limit the connection in this way.

[0086] In the above technical solution, the frame 2 of the carrier 10 is connected to the frame 1 under the transmission action of the support component 3. The support component 3 is detachably connected to the first mounting part 111 of the frame 1 through its first connecting rod 31, and detachably connected to the second mounting part 122 of the frame 1 through its second connecting rod 32. This realizes the detachable connection between the carrier 10 and the frame 1, which facilitates the separate packaging and transportation of the carrier 10 and the frame 1. The carrier 10 is replaceable in specifications compared to the frame 1. For example, it can be equipped with a variety of different specifications of carrier 10, so as to replace the corresponding carrier 10 according to the physical changes of the child during the growth process, thereby increasing the usage frequency of the main component "frame 1" of the stroller 100.

[0087] In some embodiments, the first mounting portion 111 and the second mounting portion 122 each have a mounting base 5, and the first connecting rod 31 and the second connecting rod 32 each have a fixing portion 6. The fixing portion 6 is detachably connected to the corresponding mounting base 5, and the mounting base 5 or the fixing portion 6 can rotate relative to the frame 1.

[0088] It should be noted that the connection between the first mounting part 111 and the first connecting rod 31, and between the second mounting part 122 and the second connecting rod 32, is specifically achieved through the detachable connection between the corresponding mounting base 5 and the fixing part 6. The phrase "the mounting base 5 or the fixing part 6 can rotate relative to the frame 1" includes two solutions: First, the mounting base 5 can rotate relative to the frame 1, and the fixing part 6 can be fixed in a position relative to the mounting base 5, rotating relative to the frame 1 as the mounting base 5 rotates. Second, the fixing part 6 can rotate relative to the frame 1, and the mounting base 5 can be fixed in a position relative to the frame 1. That is, the fixing part 6 is not only detachably connected to the mounting base 5, but also rotatably connected to it. The connection structure of the mounting base 5 and the fixing part 6 between the first mounting part 111 and the first connecting rod 31, and between the second mounting part 122 and the second connecting rod 32, can be the same or different; this embodiment does not limit this.

[0089] Specifically, please refer to Figure 2 and Figure 3 At least one mounting base 5 is a plug-in part 5a, which is plugged into the corresponding fixing part 6, and the mounting base 5 is rotatably connected to the frame 1.

[0090] "At least one mounting base 5 is a plug-in part 5a" can be understood as one or two mounting bases 5 being plug-in parts 5a. The most common structural form for the plug-in part 5a to be plugged into the fixing part 6 is the socket connection structure, which will not be described in detail in this embodiment.

[0091] In the above technical solution, the mounting base 5 is rotatably connected to the frame 1. The corresponding insertion part 5a of the mounting base 5 is inserted into the corresponding fixing part 6. That is, the connecting rod of the support component 3 is indirectly connected to the frame 1 through the mounting base 5. The rotatable connection of the mounting base 5 to the frame 1 enables the rotatable connection of the connecting rod of the support component 3 to the frame 1. The mutual insertion of the insertion part 5a and the fixing part 6 enables the detachable connection of the connecting rod of the support component 3 to the frame 1. The structural division of labor between the fixing part 6, the mounting base 5, and the frame 1 is clear, resulting in high connection reliability. In other embodiments, the fixing part 6 and the mounting base 5 are connected by a plug-in structure. Alternatively, the mounting base 5 can be fixedly installed, while the fixing part 6 can be rotatably installed.

[0092] Specifically, please refer to Figure 3 and Figure 4 At least one mounting base 5 is a mounting shaft 511, and the fixing part 6 corresponding to the mounting shaft 511 is a snap-fit ​​groove 611. The mounting shaft 511 is snapped into the snap-fit ​​groove 611 and rotated.

[0093] "At least one mounting base 5 is a mounting shaft 511" can be understood as one or two mounting bases 5 being mounting shafts 511. "The mounting shaft 511 is engaged with and rotatably connected to the snap-fit ​​groove 611" should be understood as the groove opening of the snap-fit ​​groove 611 being radially opened towards the mounting shaft 511, and the mounting shaft 511 being engaged with the snap-fit ​​groove 611 radially. In order to give the mounting shaft 511 the ability to transmit loads between the snap-fit ​​groove 611 and the snap-fit ​​groove 611, the opening of the snap-fit ​​groove 611 is usually set downward.

[0094] In the above technical solution, the mounting base 5 and the fixing part 6 are detachably and rotatably connected by the mounting shaft 511 and the snap-fit ​​groove 611. The structure is relatively simple and the production difficulty and production cost are low.

[0095] It should be noted that the two parallel technical features mentioned above, "at least one mounting base 5 is a plug-in part 5a, which is plugged into the corresponding fixing part 6, and the mounting base 5 is rotatably connected to the frame 1" and "at least one mounting base 5 is a mounting shaft 511, and the fixing part 6 corresponding to the mounting shaft 511 is a snap-fit ​​groove 611, and the mounting shaft 511 snaps into and is rotatably connected to the snap-fit ​​groove 611", can be set either one or both. Obviously, setting both at the same time is better.

[0096] There are four possible combinations of the mounting base 5 and the fixing part 6 between the support component 3 and the frame 1. For example, firstly, both sets of mounting bases 5 and fixing parts 6 are connected by a snap-fit ​​mechanism between the mounting shaft 511 and the snap-fit ​​groove 611; secondly, both sets of mounting bases 5 and fixing parts 6 are connected by a plug-in mechanism between the plug-in part 5a and the fixing part 6; thirdly, the first connecting rod 31 and the first mounting part 111 are connected by a snap-fit ​​mechanism between the mounting shaft 511 and the snap-fit ​​groove 611, and the second connecting rod 32 and the second mounting part 122 are connected by a plug-in mechanism between the plug-in part 5a and the fixing part 6 (e.g., ...). Figures 1 to 3 As shown), fourthly, the first connecting rod 31 is connected to the first mounting part 111 by the insertion of the insertion part 5a and the fixing part 6, and the second connecting rod 32 is connected to the second mounting part 122 by the snap-fit ​​of the mounting shaft 511 and the snap-fit ​​groove 611.

[0097] For ease of distinction, the fixing part 6, mounting part, and mounting base 5 corresponding to the first connecting rod 31 are respectively defined as the first fixing part 61, the first mounting part 111, and the first mounting base 51, and the fixing part 6, mounting part, and mounting base 5 corresponding to the second connecting rod 32 are respectively defined as the second fixing part 62, the second mounting part 122, and the second mounting base 52.

[0098] In some embodiments, the frame 1 further includes a third mounting portion 123, and a third fixing portion 63 is provided on the frame 2, the third fixing portion 63 being detachably connected to the third mounting portion 123.

[0099] It should be noted that the detachable connection between the third fixing part 63 and the third mounting part 123 can be the same as the detachable connection between the first fixing part 61 and the first mounting part 111, or the detachable connection between the second fixing part 62 and the second mounting part 122, for example... Figures 1 to 3 As shown in the embodiment, the third mounting part 123 is formed with a third mounting base 53, and the third fixing part 63 is detachably connected to the third mounting base 53. Of course, the detachable connection between the third fixing part 63 and the third mounting part 123 can also be other types of structures, and this application embodiment does not limit this.

[0100] In the above technical solution, a third fixing part 63 is provided on the frame 2, and the frame 1 is detachably connected to the third fixing part 63 through its third mounting part 123. The connection between the third fixing part 63 and the third mounting part 123 provides a more stable positioning foundation for the frame 2 compared to the frame 1, and the load-bearing capacity of the load-bearing component 10 can be significantly improved.

[0101] Specifically, the frame 1 also includes a third mounting part 123, which is disposed on the extension rod 121 extending upward from the second bracket 12, and a third fixing part 63 is disposed on the first half-frame 21 of the enclosure 2. The third mounting part 123 or the third fixing part 63 is rotatably disposed.

[0102] In some embodiments, the first mounting part 111 is a mounting shaft 511, and the fixing part 6 of the first connecting rod 31 is a snap-fit ​​groove 611; the frame 1 also includes a handrail 4 and a third connecting rod 7, the handrail 4 is connected to the second bracket 12, the third connecting rod 7 is connected to the handrail 4 and the first bracket 11, and the third connecting rod 7 is rotatably connected to the first bracket 11 through the mounting shaft 511.

[0103] In the above technical solution, the function of the third link 7 is to drive the frame 1 to fold or unfold under the drive of the handle 4. The third link 7 is rotatably connected to the first bracket 11 through the mounting shaft 511, which can increase the number of objects that the mounting shaft 511 can act on (and may also include the detachable connection objects between the first mounting part 111 and the first link 31), thereby increasing the utilization efficiency of the mounting shaft 511 and reducing the overall design redundancy of the trolley 100.

[0104] In some embodiments, the frame 1 further includes a third mounting portion 123, and the trolley 100 further includes a seat, wherein at least one of the first mounting portion 111, the second mounting portion 122, and the third mounting portion 123 is detachably mounted to the seat.

[0105] There are various types of detachable mounting structures for the seat and the mounting part, such as plug connection structure and bolt connection structure. Regardless of whether the mounting part rotates relative to the frame 1, at least after the seat is installed on the frame 1, the mounting part can be fixed in position relative to the frame 1. For example, when the mounting part can rotate relative to the frame 1, a locking structure is provided between the mounting part and the frame 1. The locking structure can be used to fix the mounting part relative to the frame 1.

[0106] The seat and the support 10 are interchangeable parts relative to the frame 1. For example, in the case of infant use, the support 10 with the frame 2 can be installed on the frame 1 so that the infant can lie down. In the case of older children use, the seat can be installed on the frame 1 so that the child can sit.

[0107] Furthermore, the presence of the first mounting part 111, the second mounting part 122, and the third mounting part 123 provides three mounting positions for the seats. In principle, the frame 1 can install three seats at the same time. In one usage scenario, the third mounting part 123 is equipped with a seat, and the trolley 100 is a single-person trolley 100. In another usage scenario, the first mounting part 111 and the third mounting part 123 are each equipped with a seat, or the second mounting part 122 and the third mounting part 123 are each equipped with a seat, or the first mounting part 111 and the second mounting part 122 are each equipped with a seat, and the trolley 100 is a double-person trolley 100.

[0108] It should be noted that the two parallel technical features mentioned above, "a third fixing part 63 is provided on the frame 2, and the third fixing part 63 is detachably connected to the third mounting part 123" and "at least one of the first mounting part 111, the second mounting part 122, and the third mounting part 123 is detachably mounted to the seat", can be provided individually or simultaneously. Obviously, providing both simultaneously is more effective.

[0109] For easier distinction, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 7 The rotation point between the upper end of the support member 121a and the first half-frame 21 is defined as the third node C; the rotation point between the first bracket 11 and the second bracket 12 is defined as the fourth node D; the rotation point between the first link 31 (or the third link 7) and the first bracket 11 is defined as the fifth node E; the rotation point between the second link 32 and the second half-frame 22 is defined as the sixth node F; the rotation point between the second link 32 and the second bracket 12 is defined as the seventh node G; and the rotation point between the third link 7 and the handrail 4 is defined as the eighth node H.

[0110] There are many structural types of the support member 10. Since the support member 10 includes a frame 2, the support member 10 can at least use its frame 2 to provide protection for the child around the perimeter. Specifically, the support member 10 is a bassinet.

[0111] Secondly, please refer to Figure 3 In one embodiment of the present invention, the sleeping basket includes a fence and a support assembly 3. The fence includes two half-frames 2a that are spliced ​​together and rotatably connected. The two half-frames 2a can rotate toward and away from each other to correspond to a second folded state and a second unfolded state. The support assembly 3 includes a first link 31 and a second link 32. One end of the first link 31 and the second link 32 are respectively connected to the corresponding half-frames 2a. The other end of the first link 31 and the second link 32 each has a fixing part 6. The fixing part 6 is configured to be detachably connected to the corresponding bracket 1a of the frame 1.

[0112] It should be noted that the frame 1 mentioned in this embodiment refers to the environmental characteristics of a sleeping basket, and the frame 1 can be the frame 1 mentioned in any of the above embodiments.

[0113] In the technical solution provided by this utility model, the two half-frames 2a that make up the frame 2 rotate and splice with each other, so that the frame 2 has a second folded state and a second unfolded state. At the same time, the two half-frames 2a are respectively provided with a first connecting rod 31 and a second connecting rod 32. Based on this, the other end of the first connecting rod 31 and the second connecting rod 32 can be detachably connected to the corresponding bracket 1a of the frame 1 through their fixing part 6, so that the first folded state and the first unfolded state of the frame 1 are correspondingly associated with the second folded state and the second unfolded state of the frame 2, thereby realizing the linkage folding and linkage unfolding of the frame 1 and the frame 2, simplifying the folding process of the trolley 100, reducing the user's operating difficulty, and thus improving the user experience. At the same time, the fixing part 6 can be detachably connected to the corresponding bracket 1a of the frame 1.

[0114] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
