[0082] While this invention has been illustrated and described with reference to specific embodiments, it should not be limited to the details shown. Rather, various modifications to these details may be made within the scope of equivalents of the claims and without departing from the invention.

[0083] The descriptions of directions such as "front", "back", "left", "right", "up", and "down" used in this document are for ease of understanding only. This invention is not limited to these directions, but can be adjusted according to actual circumstances. Although this application has been described with reference to typical embodiments, the terminology used is illustrative and exemplary, and not restrictive.

[0084] Figures 1 to 4 A perspective view of a child vehicle 1 according to one embodiment, and the vehicle body 10 and accessories 20 of the child vehicle 1 are shown respectively.

[0085] Figure 1A perspective view of a child carrier 1 according to an embodiment is shown. The child carrier 1 is, for example, a crib 1, which provides a sleeping and play space for an infant. The child carrier 1 mainly includes a carrier body 10, which, for ease of disassembly and storage, can be assembled from multiple rods 100, 110, and 120 and interconnected by multiple joints 130. These rods 100, 110, and 120 include, for example, multiple first rods 100 forming a rectangular circle, which form the upper part of the carrier body 10 as an upper frame for child support. At the joints 130 at the four corners of the upper frame formed by the first rods 100, four legs 110 in the form of rods are inserted and disposed, which are used to support the child carrier 1 on the ground. To make the four legs 110 stand more stably, support members 120 in the form of rods can be disposed between the four legs 110 to form the bottom frame of the crib 1. According to this embodiment, one end of each of the multiple support members 120 is inserted into a joint 130, and the other end is respectively fixed to the lower end of the leg 110 by bolts, for example. According to this application, a seat cover or the like can be covered on the outside of the crib 1 to form a space for infants and toddlers to play and rest, and it can also serve an aesthetic purpose, for example.

[0086] According to this application, the joint 130 can be in various forms to enable the rods 100, 110, and 120 to be assembled into a detachable child vehicle 1. This application is not limited to the specific form of the joint 130 as shown in the accompanying drawings.

[0087] according to Figure 1 To increase the versatility of crib 1 during periods when it is not used for infant sleep, multiple accessories 20, such as changing tables, bassinets, and bouncers, are detachably connected to crib 1. Figure 1 The left side schematically shows a trampoline chair, which can be formed by multiple second rods 200 forming a support 200. Cantilever arms extend downwards from the support 200, and these cantilever arms can be placed on the ground or a platform for children to jump on. Figure 1 The right side schematically shows a changing table, which can be formed by multiple second rods 200. These second rods 200 constitute a support 200 for supporting and securing the main body of the changing table that carries the child, such as boards and padding. The second rods 200 constituting the bouncy chair can be of the same form as those constituting the changing table for ease of manufacture.

[0088] According to this disclosure, a bouncy chair and a changing table are mounted side-by-side on a carrier body 10. The changing table has a length L1 and a width W1, and the bouncy chair has a length L2 and a width W2. The length L1 is substantially equal to the length L2. Since the rods are essentially the same, the bouncy chair and the changing table can be detachably fixed, for example, snapped onto the first rod 100 of the carrier body 10 using the same connecting device 30. According to this embodiment, a connecting device 30 is provided on each side of the bouncy chair and the changing table along the lengths L1 and L2, respectively. The specific internal structure of the connecting device 30 is determined according to… Figure 1 Section lines II, II-II, III-III, and IV-IV in local area A Figure 8-10 This will be explained in detail in the text.

[0089] Alternatively, the width W1 of the changing table can be equal to the width W2 of the bouncing chair so that the various accessories 20 have approximately the same profile dimensions.

[0090] Figure 2 A perspective view of the vehicle body 10 of a child vehicle 1 according to an embodiment is shown. Figure 2 The diaper changing table and bouncy chair have been removed, allowing for a better view of the vehicle body 10. The upper frame, for example, consists of eight first rods 100, with a joint 130 between every two first rods 100. The joints 130 and the first rods 100 can be connected by plugging, hinge, pivoting, etc., thus forming a rectangular upper frame. The legs 110 can be pivotally connected to the support members 120 via bolted connections, allowing the legs 110 and support members 120 to be folded together when not in use.

[0091] According to this embodiment, the first rod 100 is used for connection Figure 1At the location of the accessory 20, i.e., the connecting device 30, a locking portion 101 is provided for positioning and engaging the connecting device 30 of the accessory 20. According to this embodiment, the locking portion 101 is disposed outwardly on the first rod 100, providing installation positioning for the connecting device 30 of the bouncy chair and the changing table. Of course, the locking portion 101 can also be disposed inwardly on the first rod 100; the invention is not limited thereto. According to this embodiment, the locking portion 101 is, for example, a locking recess 101, and there are two of them to provide more stable positioning and engagement. Of course, the form and number of the locking portions 101 are not limited thereto; for example, the locking portion 101 can be a locking protrusion, and the number of locking portions 101 can be three, four, or more. The locking portions 101 are symmetrically arranged on the first rod 100 located on the other side of the carrier body 10. The engaging portion 101 can cooperate with a corresponding engaging structure (described below) provided on the connecting device 30 to position and engage the connecting device 30 onto the first rod 100. Thus, when the accessory 20 is installed onto the vehicle body 10, the corresponding engaging structure on the connecting device 30 can only engage with the vehicle body 10 when it is aligned with the engaging portion 101, thereby providing a stable and clearly visible mounting portion for the accessory 20.

[0092] Figure 3 The diagram shows a top perspective view of an accessory 20 according to one embodiment, exemplified by a diaper changing table. The main body of accessory 20 is a support portion, which includes multiple second rods 200, or may be formed by bending a single second rod 200. The support portion forms a rectangular frame structure. On opposite sides of accessory 20, a connecting device 30 is provided for engaging with the first rod 100 (see figure) of the carrier body 10. Figure 1 , 2 According to this embodiment, the connecting device 30 is disposed on the second rod 200. For example, the second rod 200 passes through and is connected to the connecting device 30, and optionally is fixedly connected to the connecting device 30.

[0093] According to this embodiment, the connecting device 30 includes a fixing base 310 and a cover 300. The cover 300 cooperates with the fixing base 310 to allow the second rod 200 to pass through and connect to the connecting device 30. The fixing base 310 and the cover 300 can be snapped together, glued together, bolted together, etc. Figure 3 As can be seen, in order to better hold the second rod 200 in place, the fixing seat 310 and the cover 300 together form a receiving portion corresponding to the cross-sectional shape of the second rod 200; that is, for example, the fixing seat 310 and the cover 300 may each have a semi-circular structure. In other embodiments, the fixing seat 310 and the cover 300 may be integrally formed.

[0094] According to this embodiment, a locking groove 320 is provided on the side of the fixing base 310 away from the second rod 200. The locking groove 320 opens vertically and extends along the extending direction of the second rod 200, thereby allowing the locking groove 320 to sit on the first rod 100 of the vehicle body 10 when the connecting device 30 is engaged with the vehicle body 10. In other words, a portion of the first rod 100 can be accommodated in the locking groove 320. With the accessory 20 and the vehicle body 10 assembled, the first rod 100 and the second rod 200 are parallel to each other (see...). Figure 1 Of course, the first member 100 and the second member 200 may not be parallel to each other. For example, the second member 200 may be distributed in a wing shape on both sides of the connecting device 30.

[0095] The connecting device 30 also includes a receiving portion 330, which is disposed on the fixed base 310 to receive the operating member 340, which is used for locking the locking accessory 20 and the carrier body 10. The structure and operation method of the operating member 340 will be discussed later. Figures 5 to 15 A detailed explanation is provided.

[0096] Figure 4 The diagram shows a bottom perspective view of the accessory 20 according to one embodiment. From the lower left connecting device 30, a receiving portion 330 can be seen, which is in the form of a notch in the fixing base 310. The main body of the operating member 340 is received in the receiving portion 330 and can slide relative to the fixing base 310 within the receiving portion 330. The operating member 340 is partially exposed outside the receiving portion 330 when not in operation. Optionally, the shape of the operating member 340 matches that of the receiving portion 330.

[0097] The interior of the locking groove 320 may be provided with connecting holes for inserting additional fixing devices, such as screws or rivets, to additionally fix the fixing seat 310 to the second rod 200 or the cover 300.

[0098] from Figure 4 The connecting device 30 in the upper right corner schematically shows the engaging ribs 321 provided in the engaging groove 320. According to this embodiment, two engaging ribs 321 are arranged laterally in the engaging groove 320, and the width of the engaging ribs 321 is... Figure 2 The width of the engaging portion 101 shown corresponds to the initial positioning and engagement of the connecting device 30.

[0099] Figures 5 to 15 A cross-sectional view and a perspective view of a connecting device 30 according to one embodiment are shown respectively.

[0100] Figure 5 The following is an illustration of a child vehicle 1 according to an embodiment. Figure 1 A bottom view of section A of section line II, parallel to the first member 100. Figure 1 The ground is cut open. The first rod 100 is located between the fixing seat 310 and the cover 300 of the connecting device 30. The first rod 100 is provided with two engaging recesses 101, each engaging recess 101 and engaging with an engaging rib 321 shown schematically. The engaging rib 321 is provided in the engaging groove 320. If the engaging recesses 101 and engaging ribs 321 are not aligned when installing the accessory 20, or if an incompatible accessory 20 is used, the accessory 20 cannot be stably installed to the first rod 100. This application avoids the risk of children being injured by being in an unstable connection of the accessory 20 by using the cooperation of the engaging ribs 321 and the engaging part 101.

[0101] like Figure 5 As shown, the mounting base 310 also includes a slide rail 350, which extends perpendicular to the plane of the paper in the figure. In the use state of the child carrier 1, the slide rail 350 optionally extends vertically. Optionally, the slide rail 350 is formed on the inner edge 331 of the receiving portion 330, protruding inward from the inner edge 331 of the receiving portion 330. The operating member 340 may be provided with a groove 348 corresponding to the shape of the slide rail 350, in which the slide rail 350 is slidably received (e.g., forming a dovetail groove fit), thereby allowing the operating member 340 to slide along the slide rail 350 in a direction perpendicular to the plane of the paper without disengaging from or deviating from the receiving portion 330. Alternatively, the mounting base 310 may be provided with a groove, while the operating member 340 may be provided with a slide rail, achieving the same sliding effect of the operating member 340 relative to the mounting base 310.

[0102] According to this embodiment, the operating member 340 includes a mounting slot 342 for mounting and fixing the drive member 370, the mounting slot 342 being in... Figure 5 The center is set perpendicular to the paper surface, and subsequent adjustments will be made according to... Figure 13 A detailed explanation follows. According to this embodiment, two mounting slots 342 are provided, and a sliding groove 348 is located between the two mounting slots 342, i.e., on the inner side. Optionally, the sliding groove 348 can also be located on the outer side of the mounting slots 342.

[0103] In this embodiment, the connecting device 30 further includes a locking member 380, which is used to engage the first rod 100, thereby locking the connection between the accessory 20 and the vehicle body 10 (hereinafter referred to as...). Figures 7-10 (Description to follow). Within the fixed base 310, a movable cavity 311 is provided on the other side of the receiving portion 330, communicating with the engaging groove 320, and the engaging member 380 is movably disposed within the movable cavity 311.

[0104] Optionally, a drive member 370 is provided between the locking member 380 and the operating member 340. The sliding of the operating member 340 along the slide rail 350 in a direction perpendicular to the paper can cause the drive member 370 to drive the locking member 380 to switch between a locked position and an unlocked position.

[0105] See Figure 6 The driving member 370 is an elongated block-shaped component, with its two ends connected to the engaging member 380 and the operating member 340, respectively. The driving member 370 includes a driving member body 371, with connecting protrusions 373 on both sides of its ends. The connecting protrusions 373 are cylindrical to facilitate insertion into the engaging member 380 or the operating member 340 and pivoting therein, thereby allowing the driving member 370 to rotate relative to the engaging member 380 and / or the operating member 340. Optionally, in this embodiment, the two ends of the driving member body 371 have the same structure and shape, and the engaging member 380 and the operating member 340 are provided with corresponding connecting structures. In other embodiments, the two ends of the driving member body 371 may have different structures and shapes; for example, the aforementioned connecting protrusion 373 may be provided on the end used to connect to one of the engaging member 380 and the operating member 340, while the other end may be constructed with other connecting structures.

[0106] Optionally, the end of the drive body 371 is provided with two opposing branches 372, and each branch 372 has the aforementioned connecting protrusion 373 on its outer side. The opposing branches 372 are spaced apart to form a deformation space 374. When the drive member 370 is connected to the engaging member 380 and / or the operating member 340, the two opposing branches 372 are pressed and deformed toward each other. After the two ends of the drive member 370 are inserted into the engaging member 380 and / or the operating member 340 and the connecting protrusion 373 is located inside the engaging member 380 and / or the operating member 340, the branches 372 move away from each other and return to their deformed state, thereby completing the assembly of the drive member 370 with the engaging member 380 and / or the operating member 340.

[0107] like Figure 7 As shown, taking the assembly of the driving member 370 and the engaging member 380 as an example, the assembly state of the driving member 370 and the engaging member 380 is illustrated. The engaging member 380 is elongated, and one end of the driving member 370 is inserted into the engaging member 380 through a connecting protrusion 373. This allows the connecting protrusion 373 of the driving member 370 to serve as a pivot point in the connecting hole 384 when the driving member body 371 of the driving member 370 needs to pivot relative to the engaging member 380. The assembly structure of the driving member 370 and the engaging member 380 is similar to the assembly structure of the operating member 340 and the driving member 370. The following description, in conjunction with... Figure 13 Describe it.

[0108] The engaging component 380 has a pivot shaft 381 and a limiting protrusion 382 on each of its two ends. The pivot shaft 381 and the limiting protrusion 382 mate with the fixing seat 310 for subsequent engagement. Figure 14 , 15 To elaborate in detail.

[0109] Figure 8 The following is an illustration of a child vehicle 1 according to an embodiment. Figure 1 A partial top sectional view of section line II-II, the section being cut between the engaging groove 320 and the second rod 200. The main body of the engaging member 380 is located in the movable cavity 311, and the end of the driving member 370 away from the engaging member 380 is inserted into the mounting groove 342 of the operating member 340. The protrusion 372 at this end is located in the connecting hole 343 of the operating member 340 and can pivot within the connecting hole 343. Figure 9 and Figure 11 As shown, the locking member 380 is movably disposed in the movable cavity 311. Specifically, the locking member 380 is rotatably disposed in the movable cavity 311 to realize the switching of the locking member 380 between the locked position and the unlocked position.

[0110] Figure 8 The diagram also shows a limiting block 344, which is connected to or formed part of the operating member 340 and is positioned in the gap between the two slide rails 350. See also Figure 10 When the operating member 340 slides downward, the limiting block 344 can abut against the abutment portion 334 of the receiving portion 330, thereby restricting the operating member 340 from continuing to move downward and preventing the operating member 340 from dislodging from the fixed base 310.

[0111] Figure 9 According to one embodiment, Figure 1 A cross-sectional view of the connecting device 30 in the locked position, with section line III-III in the middle section line III-III. Figure 8 The mounting slot is located at position 342. Figure 10 Showing according to Figure 1 A cross-sectional view of the connecting device 30 in the locked position along the mid-section line IV-IV, with the first rod 100 and joint 130 of the vehicle body 10 removed. Figure 11 According to one embodiment, Figure 1 A cross-sectional view of the connecting device 30 in the unlocked position along section line III-III. Figure 12 A cross-sectional view of the connecting device 30 according to yet another embodiment is shown.

[0112] The first rod 100 is slidably received in the upper part of the engaging groove 320 of the connecting device 30, and the second rod 200 is fixedly held by the cover 300 and the fixing seat 310. Optionally, the first rod 100 and the second rod 200 are in the same vertical plane, and the first rod 100 can slide up and down relative to the engaging groove 320 along the vertical plane to disengage from the engaging groove 320. In other embodiments, the first rod 100 and the second rod 200 may not be in the same vertical plane.

[0113] The receiving portion 330 of the connecting device 30 for accommodating the operating member 340 is located on the side of the fixed base 310 away from the first rod 100 and the second rod 200. The operating member 340 can be moved along... Figure 5 , 8 The slide rail 350, formed by the inner edge 331 of the receiving portion 330, shown in the diagram, slides up and down within the receiving portion 330 in a direction parallel to the vertical plane where the first rod 100 and the second rod 200 are located. In other embodiments, the sliding direction of the operating member 340 may not be along the vertical direction, but rather has a certain inclination relative to the vertical direction.

[0114] According to this embodiment, one end of the drive member 370 is pivotally connected to the mounting slot 343 of the operating member 340, and the drive member body 371 of the drive member 370 passes through... Figure 5 , 6 The opening 332 shown indicates that the other end of the drive member 370 is pivotally connected to the engaging member 380. The engaging member 380 can rotate within the movable cavity 311 of the fixed base 310.

[0115] Figure 9 , Figure 10 The locked position of the connecting device 30 is shown. When the operating member 340 slides downward, the operating member 340 drives one end of the driving member 370 to pivot and slide downward. The driving member body 371 pivots clockwise, causing the other end of the driving member 371 to pivot relative to the engaging member 380 and drive the end of the engaging member 380 to extend from the movable cavity 311 into the engaging groove 320 and abut against the lower side of the first rod 100. This prevents the first rod 100 from sliding relative to the engaging groove 320 and disengaging from the fixed seat 310. That is, the first rod 100 is locked in the engaging groove 320.

[0116] Figure 11 The unlocked position of the connecting device 30 is shown. When the user presses the operating member 340 upward, causing its upper end to approach the upper edge 333 of the receiving portion 330, the operating member 340 drives one end of the driving member 370 to pivot and slide upward. The driving member body 371 of the driving member 370 rotates counterclockwise, causing the other end of the driving member 371 to pivot relative to the engaging member 380 and drive the end of the engaging member 380 from... Figure 9The locking position shown retracts into the movable cavity 311 of the fixed seat 310, and the first rod 100 can slide downward relative to the fixed seat 310 along the engaging groove 320 to disengage from the fixed seat 310.

[0117] like Figure 9 , Figure 10 As shown, the upper end of the operating member 340 is provided with a buffer reset member 341. The buffer reset member 341 is, for example, a leaf spring. One end of the leaf spring abuts against the upper end of the operating member 340, and the other end is, for example, wound around the second rod member 200. Alternatively, see Figure 12 The buffer reset member 341 can also be configured as a helical spring, which is disposed in the recess 349 formed at the upper end of the operating member 340, and the upper end is limited by the protrusion 335 provided at the upper edge 333 of the receiving part 330.

[0118] A limiting block 344 is provided at the lower end of the operating member 340. The limiting block 344 abuts against the abutment 334 formed by the inner edge 331 of the receiving portion 330 to limit the downward sliding stroke of the operating member 340 relative to the fixed seat 310 and prevent the operating member 340 from disengaging from the fixed seat 310.

[0119] When the user presses the operating member 340 and slides it upward, the buffer reset member 341 acts as a buffer to prevent the operating member 340 from rigidly abutting the upper edge 333 of the receiving part. When the user releases the operating member 340 or no external force is applied to the operating member 340, the buffer reset member 341 biases the operating member 340 so that the engaging member 380 tends to move towards the locked position. In this case, the operating member 340 resets downward with the elastic force of the buffer reset member 341 until the limit block 344 abuts the abutment part 334.

[0120] Figure 13 Showing according to Figure 10 A cross-sectional view of the connecting device 30 with section line VV. The operating member 340 includes a slide groove 348, in which the slide rail 350 of the connecting device 30 is located, allowing the operating member 340 to slide up and down along the slide rail 350. Optionally, there may be two slide grooves 348, or there may be one or more.

[0121] The operating component 340 also includes a mounting groove 342 and a connecting hole 343 for mounting and positioning the drive component 370. The mounting groove 342 is vertically oriented, and the connecting hole 343 is horizontally oriented and intersects with the mounting groove 342. See also Figure 5The mounting groove 342 is substantially aligned with the opening 332 in the inner edge 331 of the receiving portion 330, and the opening 332 and the mounting groove 342 together form a channel for the drive member 370 to pass through. The body 371 of the drive member 370 spans the opening 332 and the mounting groove 342, such that one end of the drive member 370 is pivotally connected to the operating member 340, and the other end is pivotally connected to the engaging member 380. The mounting groove 342 is configured as a tapered portion near the lower part of the connecting hole 343, that is, at least a portion of the mounting groove 342 has a converging shape along the vertical direction towards the connecting hole 343. The connecting hole 343 is perpendicular to the mounting groove 342. Optionally, to facilitate tooling, the connecting hole 343 penetrates the operating member 340 from one side, that is, with Figure 13 Taking the left-side connecting hole 343 as an example, one end of it passes through the left side of the operating member 340.

[0122] During the assembly of the drive component 370 and the operating component 340, the branch portion 372 of the drive component 370, along with the connecting protrusion 373, is inserted into the mounting groove 342 from above. Upon reaching the reduced diameter portion, under the action of an external force (pushing or pulling the drive component 370 downwards), the two connecting protrusions 373 are subjected to compressive force, causing the two branch portions 372 to compress and deform within the space 374. After the connecting protrusions 373 are inserted into the connecting holes 343, the branch portions 372 recover under their own elastic force, ensuring that the end of the drive component 370 is firmly engaged with the connecting hole 343 of the operating component 340. (As described above...) Figure 7 The assembly structure of the drive member 370 and the engaging member 380 is similar to the assembly structure of the operating member 340 and the drive member 370.

[0123] like Figure 14 and 15 As shown, according to this embodiment, the drive member 370 and the operating member 340 are pivotally connected at the pivot point 345. Optionally, the pivot point 345 can be... Figure 6 , 7 The connecting protrusion 373 of the drive component 370 in 13 and Figure 13 The connecting hole 343 is formed in the middle.

[0124] The engaging member 380 can rotate within the movable cavity 311 of the fixed base 310. A guide portion 347 is vertically arranged from the bottom upwards within the movable cavity 311, dividing the lower part of the movable cavity 311 into a receiving portion 346. A pivot shaft 381 of the engaging member 380 is disposed within the receiving portion 346, for example, at the bottom of the receiving portion 346, allowing the engaging member 380 to pivot about the pivot shaft 381. The movable cavity 311 includes opposing limiting walls 312, which preferably extend vertically. When the engaging member 380 is in the locked position, a limiting protrusion 382 abuts against one of the limiting walls 312 of the movable cavity 311, and a portion of the engaging member 380 extends out of the movable cavity 311 and enters the engaging groove 320. When the engaging member 380 is in the unlocked position, it is fully retracted into the movable cavity 311, and the limiting protrusion 382 rotates to the other side of the movable cavity 311 and abuts against another limiting wall 312 of the movable cavity 311. The limiting protrusion 382 and the pivot shaft 381 cooperate with the fixed seat 310, providing more stable and controlled movement of the engaging member 380.

[0125] Optionally, the child vehicle 1 of this application may also include a load-bearing section 140. Figure 16 A child carrier 1, including a support unit 140, is shown according to one embodiment. Figure 1 Unlike other vehicles, a support section 140 is provided on the vehicle body 10 for carrying, such as for carrying a child to sleep or play. The support section 140 can be fixedly connected to, for example, the vehicle body 10 or the legs 110 in any manner.

[0126] See Figure 17 The support portion 140 is composed of multiple plates 141. Optionally, there are four plates 141 of the same shape. Connecting holes 142 are provided on the edge of each plate 141 for connecting the plates 141 together. The position of the connecting holes 142 can be adjusted as needed.

[0127] Figure 18 The connector 143 is shown, which is in the form of a hinge 143, and the hinge 143 is fixedly connected to the plate 141 through the connecting hole 142. Figure 19 The structure of a half of hinge 143 is shown, which has a joint 144. Each two halves form a hinge 143. The joints 144 of each half are aligned with each other and are passed through by a pivot (not shown), so that the two halves can pivot on each other, thereby allowing the support 140 to be folded.

[0128] By configuring the operating member 340 for releasing the accessory 20 of the crib 1 as a sliding connection to the accessory 20, and ensuring that the direction of the force applied to the operating member 340 when releasing the accessory 20 is consistent with or approximately consistent with the direction of the force applied by the user to move the accessory 20 away from the crib 1, the user can remove the accessory 20 more easily and effortlessly. Simultaneously, the operating member 340 can drive the locking member 380 to pivot via the driving member 370, converting the sliding of the operating member 340 into the pivoting of the locking member 380, resulting in a simple structure.

[0129] Since this application can be embodied in various forms without departing from the spirit and substance of this application, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted in the broadest sense within the scope defined by the claims. Therefore, all variations falling within the scope of the claims or their equivalents should be covered by the claims.
