DETAILED DESCRIPTION

[0032] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0035] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0036] like Figure 1 As shown, the child mobility device includes a riding unit 1 and a carrying unit 6; the riding unit 1 is used for children to ride, and the carrying unit 6 includes a wearing portion 61 worn on the user and a cantilever bracket 62 for suspending and supporting the riding unit 1. The lower end of the cantilever bracket 62 is connected to the wearing portion 61, and the upper end of the cantilever bracket 62 is connected to the riding unit 1 through the suspension bracket connection structure of the present application. For ease of understanding, the cantilever bracket connection structure will be described below through a specific embodiment.

[0037] One of the preferred embodiments of the present application is as follows: Figure 1 and Figure 4 As shown, a cantilever bracket connection structure includes a pair of connectors and a locking assembly 624. One of the connectors is arranged at the bottom of the riding unit 1, and the other connector is arranged at the top of the cantilever bracket 62; the two connectors can be defined as a first connector and a second connector, respectively, and the locking assembly 624 can be installed in conjunction with the first connector to form a locking cavity 6200. When the riding unit 1 and the cantilever bracket 62 need to be connected, the first connector and the locking assembly 624 can be disengaged first, so that the locking cavity 6200 is in an open state; then the second connector is extended into the opened locking cavity 6200, and finally the first connector and the locking assembly 624 are matched, so that the locking cavity 6200 holds the second connector tightly and is in a locked state. When the riding unit 1 and the cantilever bracket 62 need to be disassembled, it is only necessary to release the cooperation between the first connector and the locking assembly 624, so that the locking cavity 6200 is opened again, and then the first connector and the opened locking cavity 6200 are separated.

[0038] It is understandable that when the seating unit 1 and the cantilever bracket 62 are not connected, the locking assembly 624 is disengaged from the first connecting member, that is, the locking chamber 6200 is in an open state at this time. When the seating unit 1 and the cantilever bracket 62 need to be connected, since the locking chamber 6200 is in an open state, the second connecting member can be quickly and smoothly extended into the area of ​​the locking chamber 6200, and then the locking assembly 624 is rotated to cooperate with the first connecting member to form the locking chamber 6200 to hold and lock the second connecting member. Compared with the traditional fastening connection method, the present application can effectively improve the connection effect between the first connecting member and the second connecting member, and can also facilitate the disassembly of the first connecting member and the second connecting member.

[0039] In this embodiment, Figure 1 , Figure 4 , Figure 7 and Figure 8 As shown, the two connecting members are respectively a support member 134 arranged at the bottom of the seating unit 1, and a mounting seat 622 arranged at the top of the cantilever bracket 62; there are two specific installation methods for the locking assembly 624.

[0040] The first type: the locking assembly 624 is installed on the support member 134; when connecting the seating unit 1 and the cantilever bracket 62, the mounting seat 622 can be extended in a rod shape between the locking assembly 624 and the support member 134, and then the locking assembly 624 cooperates with the support member 134 through rotation to deform the locking cavity 6200 to achieve the clamping of the mounting seat 622.

[0041] The second type: the locking assembly 624 is installed on the mounting seat 622; when connecting the seating unit 1 and the cantilever bracket 62, the support member 134 can be extended in a rod shape between the locking assembly 624 and the mounting seat 622, and then the locking assembly 624 cooperates with the mounting seat 622 through rotation to form a locking cavity 6200 to achieve the clamping of the support member 134.

[0042] It can be understood that both of the above two methods can meet the requirements of this application; in order to facilitate the description of subsequent content, the locking assembly 624 will be described in the subsequent content using the above second installation method as an example.

[0043] In this embodiment, Figures 4 to 8As shown, a first locking groove 6221 is provided on one side of the mounting seat 622. The locking assembly 624 includes a locking body 6241, a second locking groove 6201 is provided on one side of the locking body 6241, and the locking body 6241 is installed on the first end of the first locking groove 6221 by rotating through the first end. When the riding unit 1 is connected to the cantilever bracket 62, the first locking groove 6221 can be matched with the support member 134, and then the locking body 6241 can be rotated around the first end toward the second end of the first locking groove 6221 until the second end of the locking body 6241 and the second end of the first locking groove 6221 are mutually engaged and locked, and then the first locking groove 6221 and the second locking groove 6201 can be matched to form a locking cavity 6200, and the locking cavity 6200 can hold and lock the support member 134. When the seating unit 1 and the cantilever bracket 62 need to be disassembled, the engagement between the second end of the lock body 6241 and the second end of the second lock groove 6221 can be released so that the lock body 6241 can be rotated around the installation position to open the lock cavity 6200.

[0044] In this embodiment, there are multiple ways to engage the second end of the lock body 6241 with the second end of the first lock slot 6221. One structure is as follows: Figures 5 to 8 As shown, the second end of the lock body 6241 and the second end of the first lock groove 6221 are plugged and engaged with each other through the lock tongue 6243 and the locking hole 6222; and there are two specific settings for the lock tongue 6243 and the locking hole 6222.

[0045] Arrangement mode 1: the locking tongue 6243 is installed on the mounting seat 622, and the locking hole 6222 is provided on the lock body 6241. That is, the mounting seat 622 is provided with the locking tongue 6243 at the second end of the first locking groove 6221, and the locking hole 6222 is provided at the second end of the lock body 6241. When the lock cavity 6200 is formed, the locking tongue 6243 and the locking hole 6222 can be plugged and engaged with each other.

[0046] Setting method 2: Figures 5 to 8 As shown, the locking tongue 6243 is installed on the lock body 6241, and the locking hole 6222 is provided on the mounting seat 622. That is, the mounting seat 622 is provided with a locking hole 6222 at the second end of the first locking groove 6221; the lock assembly 624 also includes a locking tongue 6243, and the locking tongue 6243 is installed on the second end of the lock body 6241. When the lock cavity 6200 is formed, the locking tongue 6243 can be plugged and engaged with the locking hole 6222.

[0047] It can be understood that the above two settings can both meet the requirements of this application; in order to facilitate the description of subsequent content, the specific settings of the lock tongue 6243 and the locking hole 6222 in the subsequent content will be described using the above two settings as an example.

[0048] Specifically, there are many ways to engage the locking tongue 6243 with the locking hole 6222. One structure is as follows: Figures 5 to 8 As shown, a locking portion 6223 is provided on one side of the locking hole 6222, and the locking tongue 6243 can be engaged with the locking portion 6223. There are many specific engagement structures between the locking tongue 6243 and the locking portion 6223, including but not limited to the following two structures.

[0049] Snap-fit ​​structure 1: Figures 5 to 8 As shown, a locking portion 6223 is fixedly provided on one side of the locking hole 6222; a locking tongue 6243 is elastically mounted on the lock body 6241, and an unlocking portion extending to the outside of the lock body 6241 is provided on the locking tongue 6243. When the locking tongue 6243 extends into the locking hole 6222, the locking tongue 6243 elastically moves and abuts against the locking portion 6223, thereby restricting the movement of the locking tongue 6243 in the direction of leaving the locking hole 6222. When it is necessary to release the lock cavity 6200 from holding the connecting portion 1305 tightly, the locking tongue 6243 is driven by the unlocking portion to move away from the locking portion 6223.

[0050] The second engaging structure: a locking portion 6223 is elastically provided on one side of the locking hole 6222, and the locking portion 6223 is provided with an unlocking portion extending to the outside of the mounting seat 622; the locking tongue 6243 is fixedly provided on the lock body 6241. When the locking tongue 6243 extends into the locking hole 6222, the locking portion 6223 elastically moves and abuts against the locking tongue 6243, thereby limiting the movement of the locking tongue 6243 in the direction of leaving the locking hole 6222. When it is necessary to release the lock cavity 6200 from holding the support member 134, the locking portion 6223 is driven by the unlocking portion to move away from the locking tongue 6243.

[0051] It can be understood that both of the above-mentioned two snap-fit ​​structures can meet the requirements of this embodiment. In snap-fit ​​structure one, the lock tongue 6243 can be elastically slidably mounted or elastically rotatably mounted; similarly, in snap-fit ​​structure two, the locking portion 6223 can be elastically slidably mounted or elastically rotatably mounted. Specifically, the elastic mounting of the lock tongue 6243 or the locking portion 6223 is achieved through the elastic member 6244; for the elastic sliding mounting, the elastic member 6244 can be a spring or a spring sheet; for the elastic rotatable mounting, the elastic member 6244 can be one of a torsion spring, a spring sheet, and a coil spring. In order to facilitate the description of the subsequent content, the subsequent content is explained by taking the lock tongue 6243 and the locking portion 6223 using the above-mentioned snap-fit ​​structure one as an example; at the same time, the lock tongue 6243 is elastically rotatably mounted, and the elastic member 6244 preferably uses a spring sheet.

[0052] Based on the above-mentioned engaging structure 1, the specific locking and unlocking process of the locking tongue 6243 and the locking portion 6223 is as follows: Figures 5 to 8 As shown, when the locking tongue 6243 extends into the locking hole 6222, the locking tongue 6243 can first rotate around the installation position away from the locking portion 6223 under the action of elastic force, until the locking tongue 6243 passes over the locking portion 6223, and then the locking tongue 6243 can be reset and rotated to the first end to cooperate with the locking portion 6223 under the action of elastic force. When the buckle body 6241 has a movement tendency in the direction of opening the buckle cavity 6200, the first end of the locking tongue 6243 abuts against the locking portion 6223 to limit the rotation of the buckle body 6241, so as to ensure that the buckle body 6241 holds the support member 134 tightly. When it is necessary to disassemble the support member 134 and the lock cavity 6200, the unlocking portion located at the second end of the lock tongue 6243 is squeezed to drive the lock tongue 6243 to rotate around the installation position in the direction away from the locking portion 6223, so as to release the abutment between the first end of the lock tongue 6243 and the locking portion 6223, and then the lock body 6241 can rotate around the installation position in the direction of opening the lock cavity 6200.

[0053] In this embodiment, there are many specific installation structures of the lock tongue 6243 on the lock body 6241, one of which is as follows: Figures 6 to 8 As shown, the second end of the lock body 6241 is provided with an extension plate 6242, and the extension plate 6242 is provided with a mounting groove 6202, and the two adjacent sides of the mounting groove 6202 are respectively provided with a first opening 6203 and a second opening 6204. The locking tongue 6243 is elastically rotatably installed in the mounting groove 6202 through an elastic member 6244, and the first end of the locking tongue 6243 can extend out of the first opening 6203, and the second end of the locking tongue 6243 can extend out of the second opening 6204 to form an unlocking portion.

[0054] When the riding unit 1 is installed with the cantilever bracket 62, the extension plate 6242 can extend into the locking hole 6222 along with the lock body 6241, and then the locking tongue 6243 can rotate under the elastic force of the elastic member 6244, so that the first end extends out of the first opening 6203 and abuts against the locking portion 6223. When the riding unit 1 needs to be disassembled from the cantilever bracket 62, the second end of the locking tongue 6243 can be squeezed at the position of the second opening 6204, so that the locking tongue 6243 drives the first end to rotate into the installation groove 6202 until the first end of the locking tongue 6243 is out of contact with the locking portion 6223.

[0055] In this embodiment, Figure 6As shown, the lock assembly 624 also includes a cover plate 6245; after the installation of the lock tongue 6243 and the elastic member 6244 is completed, the installation groove 6202 can be closed by the cover plate 6245, and then the lock tongue 6243 and the elastic member 6244 can be shielded to ensure the installation stability of the lock tongue 6243.

[0056] In this embodiment, Figure 3 , Figure 7 and Figure 8 As shown, a connection portion 1305 is provided at the lower portion of the support member 134, and a limit portion is provided at both ends of the connection portion 1305. When the riding unit 1 is connected to the cantilever bracket 62, the lock cavity 6200 can be tightly held with the connection portion 1305, and then the limit portion is against the mounting seat 622 and the lock assembly 624 in the vertical direction.

[0057] There are many specific structures of the connection portion 1305, one of which is as follows: Figure 3 As shown, a rod section is provided at the lower part of the support member 134, and baffles with a size larger than the cross-sectional size of the rod section are provided at both ends of the rod section. The rod section and the baffles at both ends can cooperate with each other to form a connecting portion 1305; wherein the baffle is a limiting portion.

[0058] In this embodiment, Figure 2 and Figure 3 As shown, the support member 134 includes a support sleeve 1343 and a support seat 1341; the support seat 1341 is fixedly connected to the upper part of the support sleeve 1343 for connecting the bracket assembly of the tensioning riding unit 1, and the connecting part 1305 is arranged at the lower part of the support sleeve 1343.

[0059] It is understandable that there are many ways to fix the support seat 1341 and the support sleeve 1343. One structure is as follows: Figure 2 and Figure 3 As shown, the size of the upper rod section of the support sleeve 1343 is smaller than that of the lower rod section, and a threaded section is provided at the top of the support sleeve 1343. When the support sleeve 1343 is connected to the support seat 1341, the support seat 1341 can be sleeved on the upper part of the support sleeve 1343, and the top end of the support sleeve 1343 extends out of the support seat 1341, and then the nut 1347 is screwed with the threaded section of the support sleeve 1343, so that the support seat 1341 is fastened to the upper part of the support sleeve 1343.

[0060] It should be known that the cross-sectional shape of the locking cavity 6200 is adapted to the cross-sectional shape of the connecting portion 1305 of the support member 134 for embracing and locking. There are many specific cross-sectional shapes, such as circular or polygonal; for example Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the cross-sectional shape of the locking cavity 6200 is circular, and the cross-sectional shape of the connecting portion 1305 is also circular. Of course, the cross-sectional shape of the connecting portion 1305 can also be circular, and the cross-sectional shape of the locking cavity 6200 can be a regular polygon; it is only necessary to ensure that the locking cavity 6200 can stably hold and lock the connecting portion 1305.

[0061] To further facilitate understanding, the specific working process of the locking assembly 624 can be described in detail below.

[0062] Initially, the lock assembly 624 maintains the lock cavity 6200 in an open state through the lock body 6241 and the mounting seat 622 .

[0063] When installing the support member 134 and the cantilever portion 62, the keyhole cavity 6200 in the open state can be aligned with the connecting portion 1305 at the bottom of the support member 134. Figure 8 As shown, the lock body 6241 is rotated around the installation position in the direction of closing the lock cavity 6200 until the extension plate 6242 provided at the second end of the lock body 6241 extends into the locking hole 6222. During the movement of the extension plate 6242 in the locking hole 6222, the locking portion 6223 can first squeeze the first end of the locking tongue 6243 so that the first end of the locking tongue 6243 is located in the installation groove 6202 and compresses the elastic member 6244 to ensure that the extension plate 6242 can smoothly and completely extend into the locking hole 6222, that is, Figure 7 shown.

[0064] When the extension plate 6242 is fully extended into the locking hole 6222, Figure 7 As shown, the locking portion 6223 loses the squeezing of the locking tongue 6243, and then the locking tongue 6243 can rotate under the elastic force of the elastic member 6244 until the first end of the locking tongue 6243 extends out of the first opening 6203 of the mounting groove 6202 and is located on one side of the locking portion 6223. At the same time, the lock body 6241 and the mounting seat 622 are completely fitted to achieve the complete closure of the lock cavity 6200 to hold and lock the connecting portion 1305. In addition, when the lock body 6241 has a movement tendency in the direction of opening the lock cavity 6200, the movement tendency of the lock body 6241 can be limited by the abutment between the locking portion 6223 and the first end of the locking tongue 6243.

[0065] When it is necessary to disassemble the support member 134 and the cantilever portion 62, Figure 8As shown, the second end of the locking tongue 6243 can be squeezed at the second opening 6204 of the mounting groove 6202, so that the locking tongue 6243 can rotate with the first end toward the mounting groove 6202 until the first end of the locking tongue 6243 is completely located in the mounting groove 6202. Then, the locking tongue 6243 is kept in the state and the lock body 6241 is rotated until the lock cavity 6200 is fully opened to achieve separation from the connecting portion 1305.
