Description

Technical Field

[0001] This application relates to the field of baby carrier technology, specifically to a skeleton structure for a baby carrier. Background Technology

[0002] A baby carrier is a tool used to carry infants, typically consisting of a frame, fabric, and a carrying system, suitable for older babies. The frame is generally made of tubular components, usually lightweight materials such as aluminum alloy. The fabric is fitted over the frame to form the baby's seat and safety harness. The carrying system includes shoulder straps and a waist belt, primarily used to secure the frame and distribute the baby's weight, reducing the burden on the carrier. To use it, the baby is placed in the seat of the frame and the safety harness is fastened. The parent carries the frame on their back, generally in an upright position, with the child facing or back to the parent. The ergonomic design ensures the baby's comfort and safety, while also making the parent's carrying relatively easy.

[0003] Chinese patent document CN216166521U discloses a detachable outdoor baby carrier, specifically disclosing a carrying frame and a seat frame located at the rear of the carrying frame. The carrying frame includes a back pad support rod and a waist belt support rod distributed from top to bottom. A back pad is installed on the back pad support rod, and a waist belt is installed on the waist belt support rod. The back pad support rod and the waist belt support rod are detachably connected. The seat frame includes a backrest rod and a support rod distributed from top to bottom. A seat frame for facilitating the baby's sitting is installed on the backrest rod, and the support rod provides support. The backrest rod and the support rod are detachably connected.

[0004] As can be seen from the accompanying drawings of the patent, in order to achieve the foldable effect of the backpack support and cockpit support, the waist belt support rod and the support rod are hinged. Specifically, the waist belt support rod and the front support rod are connected by a rotating shaft, and the front support rod and the rear support rod are connected by a folding joint. Since the rotating shaft passes directly through the waist belt support rod and the front support rod, the rotational wear of the waist belt support rod and the front support rod is relatively large. Moreover, the end of the front support rod will directly contact the ground, which can easily lead to deformation of the front support rod, and there is also a risk of cutting the user or accumulating dirt and other debris. Utility Model Content

[0005] To overcome the problem of excessive rotational wear in the prior art, this application provides a skeleton structure for an infant carrier.

[0006] This application adopts the following technical solution: a skeleton structure for an infant carrier, including a carrying frame and a folding frame, wherein the carrying frame and the folding frame are connected by a connector, and the folding frame can rotate around the connector; The connector includes a fixing part and a rotating part. The fixing part is provided with a slot for fixing the back support, and the rotating part is provided with a rotating cavity. The end of the folding support is inserted into the rotating cavity. A rotating shaft is provided on the rotating part, and the rotating shaft passes through the end of the folding bracket, allowing the folding bracket to rotate around the rotating shaft.

[0007] Optionally, the carrying support is U-shaped, and the folding support includes a front support and a rear support. Both the front support and the rear support are U-shaped. Each of the two vertical ends of the front support is provided with a folding joint, and the ends of the two vertical ends of the rear support are respectively and correspondingly inserted into the two folding joints. The two vertical ends of the front bracket are inserted into the rotating cavity and sleeved on the outside of the rotating shaft.

[0008] Optionally, the portion of the front support located below the folding joint is bent away from the rear support; The rear support has a support member on each side of its horizontal end. The bottom of the support member has a protrusion that contacts the ground and supports the rear support.

[0009] Optionally, one end of the rotating shaft abuts against the outer wall of one side of the rotating part, and the other end of the rotating shaft passes through the rotating cavity and through the front bracket to extend to the other side of the rotating part. A locking nut is adaptedly provided at the other end of the rotating shaft.

[0010] Optionally, a rubber pad is provided on the inner side of the end of the front bracket, and a rotating sleeve is fitted on the outer side of the rotating shaft. The rubber pad has a through hole, and the rotating sleeve passes through the through hole. The outer wall of the rubber pad and the inner wall of the front bracket, as well as the outer wall of the rotating sleeve and the inner wall of the perforation, are both interference fits.

[0011] Optionally, both ends of the rotating sleeve extend between the outer wall of the front bracket and the inner wall of the rotating cavity, and the outer diameter of the end of the rotating sleeve is larger than the outer diameter of the middle part of the rotating sleeve.

[0012] Optionally, a few reinforcing plates are provided between the rotating part and the fixed part, and a support column is provided at the bottom of the rotating part, with a hemispherical protective pad fitted on the support column.

[0013] In summary, this application includes the following beneficial technical effects: 1. The carrying frame and the folding frame are connected by a connector. The folding frame can rotate around the connector. The connector includes a fixed part and a rotating part. The end of the folding frame is inserted into the rotating cavity of the rotating part and rotates through the rotating shaft. This avoids the rotating shaft passing directly through the carrying frame and the folding frame, effectively reducing the rotational wear of the carrying frame and the folding frame during rotation. Moreover, the end of the folding frame is located inside the rotating cavity, so it will not injure the user.

[0014] 2. The part of the front support located below the folding joint is bent away from the rear support. This bending design can prevent the front support and the rear support from directly touching, thus preventing pinching. Attached Figure Description

Detailed Implementation

[0016] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0017] like Figure 1-5As shown, a baby carrier frame structure includes a carrying frame 1, a folding frame 2, and a connector 3. The carrying frame 1 and the folding frame 2 are connected by the connector 3. The folding frame 2 can rotate around the connector 3, achieving convenient folding and reducing rotational wear. Specifically, the connector 3 includes a fixing part 31 and a rotating part 32. The fixing part 31 has a slot 310, which can be U-shaped or similar, and its function is to fix the carrying frame 1. The rotating part 32 has a rotating cavity 321, which has sufficient space to ensure that the folding frame 2 can rotate smoothly within it. The end of the folding frame 2 is inserted into the rotating cavity 321. In this way, while enabling reliable rotation of the folding frame 2, the rotating cavity 321 also serves to wrap around the end of the folding frame 2. A rotating shaft 33 passes through the rotating part 32 and passes through the end of the folding frame 2, allowing the folding frame 2 to rotate around the rotating shaft 33. One end of the rotating shaft 33 abuts against the outer wall of one side of the rotating part 32, and the other end of the rotating shaft 33 passes through the rotating cavity 321 and through the front bracket 21 and extends to the other side of the rotating part 32. The other end of the rotating shaft 33 is fitted with a locking nut 331, which can ensure the axial fixation of the rotating shaft 33 and prevent it from loosening.

[0018] The carrying frame 1 is U-shaped, which better conforms to the back of the user. It is usually made of lightweight materials such as aluminum alloy, which ensures strength while reducing weight. The folding frame 2 includes a front frame 21 and a rear frame 22, both of which are U-shaped. Each of the two vertical ends of the front frame 21 is provided with a folding joint 23. The ends of the two vertical ends of the rear frame 22 are respectively and correspondingly inserted into the two folding joints 23. In this way, the front frame 21 and the rear frame 22 can rotate relative to each other, realizing the folding frame 2 itself. The two vertical ends of the front support 21 are inserted into the rotating cavity 321 and sleeved on the outside of the rotating shaft 33. This ensures that the front support 21 can rotate around the rotating shaft 33 within the rotating cavity 321. Since the front support 21 and the backpack support 1 are not directly connected through the rotating shaft 33, and the rotation of the front support 21 is completed within the accommodating cavity, excessive wear of the backpack support 1 or the front support 21 caused by direct connection is avoided. Furthermore, under the covering effect of the connector 3, the ends of the front support 21 are not exposed, which prevents the ends of the front support 21 from directly contacting the ground and deforming or adhering to dirt or other debris. At the same time, it also prevents the user from accidentally touching the ends of the front support 21 and causing cuts.

[0019] The portion of the front support 21 located below the folding joint 23 bends away from the rear support 22. This ensures that even after the front and rear supports 21 are fully folded, a certain distance remains between them, preventing pinching injuries and allowing the user to quickly fold the folding support 2. Each side of the rear support 22 has a support member 221, which can be made of plastic or rubber and can be columnar or block-shaped. The bottom of the support member 221 has a protrusion 222, which can be circular or square. The protrusion 222 contacts the ground and supports the rear support 22, preventing it from directly contacting the ground and deforming. A support column 322 is located at the bottom of the rotating part 32, and a hemispherical protective pad 323 is fitted onto the support column 322. The cooperation between the protective pad 323 and the support column 322 prevents the connecting part 3 from directly contacting the ground and breaking.

[0020] A rubber pad 34 is provided on the inner side of the end of the front bracket 21, and a rotating sleeve 332 is fitted on the outer side of the rotating shaft 33, which has good wear resistance and self-lubricating properties. The rubber pad 34 has a through hole 340, and the rotating sleeve 332 passes through the through hole 340. The outer wall of the rubber pad 34 and the inner wall of the front bracket 21, and the outer wall of the rotating sleeve 332 and the inner wall of the through hole 340, are both interference fits. This ensures the fixation of the rubber pad 34 and the rotating sleeve 332 and prevents them from loosening. Both ends of the rotating sleeve 332 extend between the outer wall of the front bracket 21 and the inner wall of the rotating cavity 321. The outer diameter of the end of the rotating sleeve 332 is larger than the outer diameter of the middle part of the rotating sleeve 332. That is, the end of the rotating sleeve 332 has a flange that folds away from the rotating sleeve 332, thereby limiting the rotating sleeve 332 on the front bracket 21 and preventing the rotating sleeve 332 from falling off. Several reinforcing plates 35 are provided between the rotating part 32 and the fixed part 31. The reinforcing plates 35 can be triangular, rectangular or other shapes. The function of the reinforcing plates 35 is to enhance the strength of the connecting part 3 and ensure its stability.

[0021] Furthermore, since the connector 3 and the support 221 are provided, and the support column 322 is provided at the bottom of the connector 3 and the protrusion 222 is provided at the bottom of the support 221, the carrying frame and the folding frame will not directly contact the ground. At the same time, the support column 322 and the protrusion 222 are located on the outermost side of the frame structure, which can significantly improve the stability of the frame structure after placement.

[0022] The implementation principle of this embodiment is as follows: the carrying support 1 and the folding support 2 are connected by a connector 3, and the folding support 2 is connected to the connector 3 by a rotating shaft 33, making the rotation of the folding support 2 smoother. The folding support 2 is not directly connected to the carrying support 1, which effectively reduces rotational wear. Moreover, the end of the folding support 2 is wrapped by the connector 3, with no sharp or pointed parts exposed, effectively preventing users from being cut due to accidental contact. At the same time, the cooperation between the rubber pad 34 and the rotating sleeve 332 further reduces wear during the rotation process.

[0023] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
