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 1As 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] Embodiment 1:

[0038] like Figure 1 and Figure 2 As shown, a cantilever bracket connection structure includes a support member 134 disposed at the bottom of the riding unit 1, and a connector disposed at the top of the cantilever bracket 62. When the riding unit 1 and the cantilever bracket 62 are connected, the riding unit 1 and the cantilever bracket 62 can be plugged into each other through the connector and the support member 134; and after the plugging is completed, the support member 134 and the connector can be locked by a locking structure, thereby ensuring that the support member 134 and the connector cannot slide relative to each other in the plugging direction, thereby achieving a stable connection between the riding unit 1 and the cantilever bracket 62. When the riding unit 1 and the cantilever bracket 2 need to be disassembled, the locking structure can be unlocked through the action of the support member 134 or the connector, and then the support member 134 and the connecting rod can be separated from each other.

[0039] It should be known that when connecting the riding unit 1 and the cantilever bracket 62, the riding unit 1 and the cantilever bracket 62 can be quickly installed or removed by plugging the support member 134 into the connector. However, a simple plug-in structure cannot provide a stable connection, so a locking structure is provided between the support member 134 and the connector. The locking structure can lock the movement of the connector and the support member 134 along the plug-in separation direction to ensure the structural connection stability of the riding unit 1 and the cantilever bracket 62. When disassembling the riding unit 1 and the cantilever bracket 62, no additional tools are required, and the locking of the locking structure can be released by operating the support member 134 or the connector. Compared with the fastening connection method, the present application can effectively improve the convenience of users when installing or disassembling the riding unit 1 and the cantilever bracket 62.

[0040] It can be understood that the plug-in structure of the support member 134 and the connector is a connection structure of a hole and an axis; then the plug-in of the support member 134 and the connector can be divided into two situations; either the support member 134 is provided with a hole and the connector serves as an axis, or the support member 134 is the axis and the connector is provided with a hole; both situations can meet the plug-in connection requirements of this application. At the same time, for the unlocking of the locking structure, the action of the support member 134 can be used as the unlocking source, or the action of the connector can be used as the unlocking source. Therefore, in order to facilitate the description of the subsequent content, the subsequent content will be described as an example in which the connector serves as the axis and the action of the support member 134 serves as the unlocking source of the locking structure.

[0041] Specifically, Figure 3 , Figure 8 and Fig. 9 As shown, a through hole 1302 is vertically provided at the center of the support member 134, and the connecting member is a connecting rod 623, which is vertically fixed to the upper end of the cantilever bracket 62. The connecting rod 623 can be plugged into the through hole 1302 and locked by a locking structure. When the connecting rod 623 is separated from the through hole 1302, the locking structure can be unlocked by the action of the support member 134.

[0042] In this embodiment, Figure 3 , Figure 5 and Figure 8 As shown, a locking block 1344 is installed on the side wall of the through hole 1302, and a locking groove 6230 is provided on the outer side wall of the connecting rod 623. When the connecting rod 623 and the through hole 1302 are plugged in, the locking block 1344 can approach the locking groove 6230 and engage with it to form a locking structure. That is, the locking block 1344 and the locking groove 6230 are engaged in the radial direction of the connecting rod 623, and then the movement tendency of the connecting rod 623 and the through hole 1302 to separate from each other in the axial direction will be limited by the engagement of the locking block 1344 and the locking groove 6230.

[0043] It is understandable that the specific structure of the locking block 1344 can be various, such as Figure 5 and Figure 8The rod shape shown may be plate-shaped or block-shaped, as long as it can engage with the locking groove 6230. The number of locking blocks 1344 is at least one. In order to improve the locking stability of the locking block 1344 and the locking groove 6230, the number of locking blocks 1344 may be multiple, and the multiple locking blocks 1344 may be arranged at equal intervals along the circumferential direction of the through hole 1302. Then, the locking groove 6230 may be arranged in a corresponding number of locking blocks 1344, or may be arranged in an annular shape along the circumferential direction of the connecting rod 623. In order to improve the convenience of plugging the connecting rod 623 and the through hole 1302, the present embodiment preferably adopts an annular arrangement for the locking groove 6230, so that when the riding unit 1 and the cantilever bracket 62 are plugged in at any circumferential angle, the locking groove 6230 can be smoothly engaged with the multiple locking blocks 1344.

[0044] In this embodiment, Figure 5 , Figure 8 and Fig. 9 As shown, the support member 134 includes a support sleeve 1343 and a stopper sleeve 1345. The through hole 1302 is arranged at the center of the support sleeve 1343, and the stopper sleeve 1345 is installed on the outside of the support sleeve 1343 and can move axially along the support sleeve 1343. After the connection rod 623 and the through hole 1302 are plugged in, the stopper sleeve 1345 can move axially along the support sleeve 1343 to the first position, and in this process, the stopper sleeve 1345 can drive the locking block 1344 to move in the direction of the through hole 1302 until the locking block 1344 is locked and engaged with the locking groove 6230. When it is necessary to separate and disassemble the connecting rod 623 and the through hole 1302, the stop sleeve 1345 can be moved axially along the support sleeve 1343 to the second position. During this process, the stop sleeve 1345 gradually breaks away from the contact with the locking block 1344, and then the stop sleeve 1345 loses the movement restriction on the locking block 1344, thereby realizing the unlocking of the connecting rod 623 and the support member 1344, and the connecting rod 623 can be separated from the through hole 1302 subsequently.

[0045] In this embodiment, there are multiple specific installation methods for the locking block 1344, including but not limited to the following two.

[0046] Installation method 1: The side of the support sleeve 1343 is provided with an open groove in a vertical direction, and the open groove can connect the through hole 1302 with the outside. The locking block 1344 is installed on the side of the support sleeve 1343 by rotating the first end; the rotation plane of the locking block 1344 coincides with the vertical plane passing through the axis of the through hole 1302; that is, the locking block 1344 can rotate toward the axis position close to the through hole 1302. Therefore, after the support member 134 and the connecting rod 623 are plugged in, the locking block 1344 can rotate toward the direction close to the connecting rod 623 until the second end of the locking block 1344 is engaged with the locking groove 6230. The rotation of the locking block 1344 can be driven by the stopper 1345 moving from the second position to the first position, and the stopper 1345 can stop at the first position to limit the movement trend of the locking block 1344 in the direction away from the connecting rod 623.

[0047] Installation method 2: Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, a sliding hole 1303 is radially arranged on the side of the support sleeve 1343. The locking block 1344 is slidably mounted in the sliding hole 1303, and the length of the locking block 1344 is greater than the thickness of the support sleeve 1343, that is, the extension length of the sliding hole 1303. Therefore, after the support member 134 and the connecting rod 623 are plugged in, the stopper 1345 can squeeze the locking block 1344 to the first end outside the support sleeve 1343 during the process of moving from the second position to the first position, and then the locking block 1344 can slide along the sliding hole 1303 until the second end of the locking block 1344 is engaged with the locking groove 6230. At this time, the stopper 1345 can stop at the first position to limit the movement trend of the locking block 1344 in the direction away from the connecting rod 623.

[0048] It is understandable that both of the above two installation methods can meet the use requirements of this embodiment. In the first installation method, the locking block 1344 can be freely rotated, that is, the rotation of the locking block 1344 out of the locking groove 6230 can rely on the weight of the locking block 1344 itself, or it can rely on the squeezing of the connecting rod 623 to separate the arc or wedge-shaped fit between the locking block 1344 and the locking groove 6230. The locking block 1344 can also be installed by elastic rotation through an elastic member, such as a torsion spring, that is, the rotation of the locking block 1344 can be automatically performed under the elastic force of the torsion spring.

[0049] Similarly, in the second installation method, the locking block 1344 can be installed by free sliding, or can be installed by elastic sliding through an elastic member, such as a spring. The specific installation position and installation method of the torsion spring or spring are conventional settings for those skilled in the art, so they will not be elaborated in detail here. In order to facilitate the description of the subsequent content, the subsequent content is described by taking the locking block 1344 using the above-mentioned second installation method as an example.

[0050] It can also be understood that the movement of the stopper 1345 from the first position to the second position can be a downward movement or an upward movement. Considering that the stopper 1345 needs to maintain contact with the locking block 1344 in the first position, the movement of the stopper 1345 from the first position to the second position in this embodiment is preferably an upward movement; that is, the movement of the stopper 1345 from the first position to the second position needs to overcome its own gravity.

[0051] In this embodiment, there are many specific structures of the blocking sleeve 1345, including but not limited to the following two.

[0052] Structure 1: The inner side of the lower end of the stopper sleeve 1345 is a wedge-shaped or arc-shaped structure, so that when the stopper sleeve 1345 moves from top to bottom to the first position, the stopper sleeve 1345 can be squeezed with the first end of the locking block 1344 through the arc-shaped or wedge-shaped structure at the lower end, thereby driving the locking block 1344 to slide along the sliding hole 1303. When the stopper sleeve 1345 moves from bottom to top to the second position, the stopper sleeve 1345 can be separated from the locking block 1344, and there is a gap between the lower end of the stopper sleeve 1345 and the locking block 1344 in the axial direction of the support sleeve 1343.

[0053] Structure 2: Figures 7 to 9 As shown, the inner wall of the stopper sleeve 1345 is provided with a locking area 1306 and an unlocking area 1307 along the axial direction, and the distance from the locking area 1306 to the center of the through hole 1302 is smaller than the distance from the unlocking area 1307 to the center of the through hole 1302; that is, in the radial direction, the locking area 1306 is in contact with the outer side of the support sleeve 1343, and the unlocking area 1307 is spaced apart from the outer side of the support sleeve 1343. Therefore, when the stopper sleeve 1345 moves from top to bottom to the first position, the stopper sleeve 1345 can correspond to and contact the locking block 1344 through the locking area 1306. When the stopper sleeve 1345 moves from bottom to top to the second position, the stopper sleeve 1345 can correspond to the locking block 1344 through the unlocking area 1307.

[0054] It can be understood that both structures can meet the requirements of this embodiment, and the difference between structure 1 and structure 2 is that the length of the stopper sleeve 1345 corresponding to structure 2 is longer than that of the stopper sleeve 1345 corresponding to structure 1. Of course, for structure 2, the stopper sleeve 1345 can block the locking block 1344 during the entire movement of the stopper sleeve 1345, and the distance from the unlocking area 1307 to the outside of the support sleeve 1343 is less than the length of the locking block 1344, thereby preventing the locking block 1344 from sliding out of the sliding hole 1303. Therefore, in this embodiment, the specific structure of the stopper sleeve 1345 can preferably adopt the above-mentioned structure 2.

[0055] In this embodiment, there are multiple specific configurations for the axial movement of the stopper sleeve 1345, including but not limited to the following two.

[0056] Arrangement method 1: the stop sleeve 1345 is threadedly connected to the support sleeve 1343; thus, the stop sleeve 1345 can be rotated around the support sleeve 1343 to move axially along the support sleeve 1343, thereby driving the locking block 1344 to lock or unlock.

[0057] Setting method 2: Figures 7 to 9 As shown, the stop sleeve 1345 is slidably connected to the support sleeve 1343 ; thus, the locking block 1344 is driven to lock or unlock by the axial sliding of the stop sleeve 1345 along the support sleeve 1343 .

[0058] It can be understood that both setting mode 1 and setting mode 2 can meet the requirements of this embodiment. For setting mode 2, when the locking block 1344 is in the locked state, the stopper 1345 is located at the first position, that is, the lowest position of the moving stroke of the stopper 1345; then the unlocking direction of the stopper 1345 to the locking block 1344 is vertically upward, but the stopper 1345 always maintains a downward movement trend under the action of gravity. That is, the stopper 1345 in setting mode 2 can be self-locked by gravity; at the same time, the unlocking operation mode of the stopper 1345 to the locking block 1344 in setting mode 2 is simpler than that in setting mode 1, so the above-mentioned setting mode 2 is preferably adopted for the axial movement setting mode of the stopper 1345 in this embodiment.

[0059] Specifically, Figure 5 , Figure 8 and Fig. 9 As shown, the blocking sleeve 1345 and the supporting sleeve 1343 are elastically connected via an elastic member 1346; the elastic member 1346 can always produce a downward movement trend for the blocking sleeve 1345, so that when the blocking sleeve 1345 is located in the first position, the blocking sleeve 1345 can remain stationary under the combined action of its own gravity and the elastic force of the elastic member 1346, thereby further improving the locking stability of the blocking sleeve 1345 on the locking block 1344.

[0060] It should be known that the specific structure and working principle of the elastic member 1346 are well known to those skilled in the art, and common elastic members 1346 include springs and shrapnel.

[0061] In this embodiment, the seating unit 1 is supported and tensioned by a bracket assembly, and the lower end of the bracket assembly can be fixedly connected to the support sleeve 1343 to achieve the entire support of the seating unit 1 by the support sleeve 1343.

[0062] For ease of understanding, the specific connection process between the cantilever bracket 62 and the riding unit 1 may be described in detail below.

[0063] When it is necessary to connect the cantilever bracket 62 with the seating unit 1, first operate the stop sleeve 1345 to move axially upward along the support sleeve 1343 and compress the elastic member 1346, so that the unlocking area 1307 of the stop sleeve 1345 corresponds to the position of the locking block 1344, and then the locking block 1344 is in a free state along the sliding hole 1303.

[0064] Then, if Fig. 9 As shown, the connecting rod 623 is aligned with the through hole 1302 and inserted. During the process of inserting the connecting rod 623 into the through hole 1302, the connecting rod 623 can be squeezed and contacted with the second end of the locking block 1344 through the arc or wedge-shaped surface at the top, and then the locking block 1344 is squeezed into the sliding hole 1303 to ensure that the connecting rod 623 can smoothly enter the through hole 1302 until the locking groove 6230 corresponds to the position of the locking block 1344.

[0065] Then, if Figure 8 As shown, the stopper sleeve 1345 is released, and the stopper sleeve 1345 can move axially downward along the support sleeve 1343 under the gravity and the elastic force of the elastic member 1346. During the axial downward movement of the stopper sleeve 1345, the stopper sleeve 1345 can contact the first end of the locking block 1344 through the locking area 1306, and then the locking block 1344 slides along the sliding hole 1303 into the through hole 1302 under the pressure of the locking area 1306, until the second end of the locking block 1344 is engaged with the locking groove 6230, thereby always locking the connecting rod 623 and the support member 134. In addition, the stopper sleeve 1345 will be stationary at the first position to ensure that the locking effect of the locking structure is continuously effective.

[0066] When it is necessary to disassemble the cantilever bracket 62 and the seating unit 1, the above process can be performed in reverse.

[0067] Embodiment 2:

[0068] Compared with the first embodiment, the difference of this embodiment is that: Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, the support member 134 also includes a support seat 1341, and the support sleeve 1343 is fixedly arranged with the support seat 1341; thus, the bracket assembly of the riding unit 1 can be supported and connected with the support sleeve 1343 through the support seat 1341. The stopper sleeve 1345 is located in the support seat 1341 and cooperates with the connection structure, and then the stopper sleeve 1345 moves along the axial direction of the support sleeve 1343 by cooperating with the support seat 1341.

[0069] In this embodiment, there are multiple specific configurations for the stopper sleeve 1345 to move axially through the connection structure with the support seat 1341 , including but not limited to the following two.

[0070] Arrangement method 1: The stopper sleeve 1345 is threadedly connected to the support seat 1341 through the outer side.

[0071] Setting method 2: Figure 8 and Fig. 9 As shown, the blocking sleeve 1345 is elastically connected to the support seat 1341 through the elastic member 1346 ; under the action of the elastic member 1346 , the blocking sleeve 1345 always has a downward movement trend.

[0072] In this embodiment, Figure 5 , Figure 8 and Fig. 9 As shown, the support member 134 also includes a connecting seat 1342, which is connected to the bottom of the blocking sleeve 1345 through the top; the connecting seat 1342 can extend to the outside of the support seat 1341, thereby driving the connecting seat 1342 to drive the blocking sleeve 1345 to move.

[0073] In this embodiment, there are multiple ways to fix the support seat 1341 and the support sleeve 1343. One structure is as follows: Figure 5 , Figure 6 , Figure 8 and Fig. 9 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.
