Description

Technical Field

[0001] This invention relates to the field of children's products technology, specifically to a baby carrier and its carrier. Background Technology

[0002] In existing technologies, some child carriers include a frame and a carrier. The carrier is detachably connected to the frame. The carrier can be installed on the frame to use the carrier as a stroller, or it can be detached from the frame for separate use, or removed from the frame and installed in a car seat for use as a child car seat. The carrier includes a seat and a backrest that are rotatably connected. When the carrier is installed on the frame, the backrest can rotate relative to the seat, thereby adjusting the carrier's posture to a sitting or reclining position to improve comfort. However, when the carrier is detached from the frame, if the backrest is rotated relative to the seat to a reclining position and the carrier is installed face-up in a car seat, the inertia from sudden braking or a collision can cause the infant's head and neck to violently swing forward due to lack of back support, easily leading to cervical spine fracture or spinal cord injury. Simultaneously, the body can easily slip, causing the seatbelt to strangle the infant or causing abdominal organ contusions. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by providing a basket in which the seat and backrest cannot rotate relative to each other after being removed from the support.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A carrying basket is detachably mounted on a bracket. The carrying basket includes a seat, a backrest rotatably connected to the seat, and an attitude locking structure disposed between the seat and the backrest. The attitude locking structure has a locked state that locks the relative position between the seat and the backrest and an unlocked state that allows the seat and the backrest to rotate relative to each other. When the basket is detached from the bracket, the posture locking structure is in a locked state, and a first angle is formed between the seat and the backrest; when the basket is installed on the bracket, the posture locking structure is in an unlocked state, the backrest and the seat can rotate relative to each other, and the angle formed between the backrest and the seat is not less than the first angle.

[0005] In some embodiments, the posture locking structure includes a posture locking member movably disposed on one of the seat and the backrest, and a posture locking part disposed on the other; when the posture locking structure is in a locked state, the posture locking member engages with the posture locking part; when the posture locking structure is in an unlocked state, the posture locking member disengages from the posture locking part.

[0006] In some embodiments, the bracket is provided with a driving part, and when the basket is installed on the bracket, the driving part drives the attitude locking member to move, so that the attitude locking member disengages from the attitude locking part.

[0007] In some embodiments, the attitude locking member is provided with an abutment portion. When the basket is installed on the bracket, the driving part abuts against the abutment portion to disengage the attitude locking member from the attitude locking portion. Alternatively, the basket may include a linkage movably disposed on one of the seat and the backrest, the linkage being connected to or cooperating with the posture locking member to disengage the posture locking member from the posture locking part. When the basket is mounted on the bracket, the drive unit acts on the linkage.

[0008] In some embodiments, the basket further includes a bracket disposed on the seat or the backrest for connection with the support, the bracket having a socket, the abutment or the linkage extending into the socket, the support being provided with a plug that matches the socket, when the basket is mounted on the support, the plug is inserted into the socket, the plug abuts and engages with the abutment or the linkage, and the plug forms the drive portion.

[0009] In some embodiments, the posture locking member is rotatably disposed on the seat about a pivot axis, and the posture locking member is provided with a backrest hook. When the posture locking structure is in the locked state, the backrest hook is engaged with the posture locking member; when the posture locking structure is in the unlocked state, the backrest hook is disengaged from the posture locking member.

[0010] In some embodiments, the posture locking part is a protrusion provided on the backrest, the protrusion extending obliquely upward from the backrest from front to back, and the backrest hook rotating forward and upward to disengage from the protrusion.

[0011] In some embodiments, the attitude locking member is provided with a stop portion, and when the basket is installed on the bracket, the driving part drives the stop portion to move; The backrest hook and the abutment are located on the same side of the pivot, and the abutment is located below the backrest hook; The posture locking member is provided with an extension that extends downward from the seat towards the backrest, and the abutment is a fixed shaft fixedly disposed at the lower end of the extension.

[0012] In some embodiments, the basket further includes a first elastic member for automatically resetting the posture locking structure to a locked state. The first elastic member is disposed between the seat or the backrest and the posture locking member to drive the posture locking member to have a tendency to move in a direction that cooperates with the posture locking part.

[0013] In some embodiments, when the basket is mounted on the bracket, the backrest and the seat have multiple relative rotational positions. The basket further includes a locking structure for locking the basket in each of the positions. The locking structure includes a locking member disposed on one of the seat and the backrest and a locking hole disposed on the other. At least two locking holes are spaced apart. When the locking structure is in a locked state, the locking member is inserted into one of the locking holes; when the locking structure is in an unlocked state, the locking member is disengaged from all of the locking holes. The basket also includes a gear unlocking structure for driving the gear locking structure to unlock. The gear unlocking structure includes a gear operating member slidably disposed on the seat or the backrest and a connector connected between the gear locking member and the gear operating member.

[0014] In some embodiments, the basket further includes a connection locking structure that locks the position between the basket and the bracket when the basket is mounted on the bracket, the connection locking structure including a movable connection locking member, the connection locking structure having a locked state and an unlocked state; When a first angle is formed between the seat and the backrest, the connection locking structure can switch between a locked state and an unlocked state; when the angle formed between the backrest and the seat is greater than the first angle, the connection lock remains locked and cannot be unlocked.

[0015] The present invention also provides a carrier, including a support frame and a basket as described in any of the preceding claims; The bracket is provided with a driving unit. When the basket is installed on the bracket, the driving unit drives the attitude locking structure to unlock. The support frame is a trolley frame.

[0016] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: In the basket of the present invention, when the basket is installed on the bracket, the posture locking structure is in the unlocked state, allowing the backrest and seat to rotate relative to each other to adjust their positions, thereby enabling the basket to be in various usage postures, such as a sitting posture and a reclining posture, which can improve the comfort during use. When the basket is detached from the bracket, the posture locking structure is in the locked state, and the backrest and seat cannot rotate relative to each other, keeping the basket in a sitting posture. This avoids the problem of the basket being installed face-up on a car seat in other usage postures besides the sitting posture, such as a reclining posture, thereby improving the safety performance of the basket during use.

Figure 6 In the figure, the right direction is "rear", the left direction is "front", the upper direction is "up", and the lower direction is "down". The directions perpendicular to the paper are "left" and "right".

[0021] Example 1 like Figures 1-10 As shown, the carrier in this embodiment includes a support 1 and a basket 2 mounted on the support 1.

[0022] The carrier 2 is detachably mounted on the bracket 1. When the carrier 2 is mounted on the bracket 1, the vehicle can be used as a stroller, with the bracket 1 serving as the stroller frame. After the carrier 2 is detached from the bracket 1, it can be used independently, or it can be directly mounted on a car seat, or mounted on the base of a child car seat. Furthermore, the vehicle can also be used as a child car seat by folding the bracket 1 and mounting it together with the carrier 2 on a car seat, or on the base of a child car seat.

[0023] The carrying basket 2 includes a seat 21 and a backrest 22 rotatably connected to the seat 21. The seat 21 is mounted on a support 1, and the backrest 22 can rotate relative to the seat 21, thus forming different angles between the backrest 22 and the seat 21, allowing the carrying basket 2 to be in different usage postures, such as a sitting posture or a reclining posture. Alternatively, the backrest 22 can be mounted on the support 1, allowing the seat 21 to rotate relative to the backrest 22 to also allow the carrying basket 2 to be in different usage postures. When the carrying basket 2 is in a sitting posture, the backrest 22 forms a first angle with the seat 21, such as... Figures 1-6 , Figure 11 and Figure 12 As shown. When the basket 2 is in a reclining or other usage posture, the angle formed between the backrest 22 and the seat 21 is greater than the first angle, such as... Figures 7-10 and Figure 13 As shown.

[0024] The basket 2 also includes a posture locking structure, which is located between the seat 21 and the backrest 22. The posture locking structure has a locked state and an unlocked state. When the posture locking structure is in the locked state, it locks the relative position between the seat 21 and the backrest 22, preventing relative rotation between them. When the posture locking structure is in the unlocked state, the backrest 22 and the seat 21 can rotate relative to each other to adjust the usage posture of the basket 2.

[0025] In this embodiment, when the posture locking structure is in the locked state, the basket 2 is in a seated usage posture, that is, a first angle is formed between the backrest 22 and the seat 21. When the posture locking structure is in the unlocked state, the backrest 22 and the seat 21 can rotate relative to each other to switch between various usage postures, and at this time the angle formed between the backrest 22 and the seat 21 is not less than the first angle.

[0026] The posture locking structure includes a posture locking member 23 movably mounted on the seat 21 and a posture locking part 221 mounted on the backrest 22. When the posture locking structure is in the locked state, the posture locking member 23 and the posture locking part 221 cooperate to fix the seat 21 and the backrest 22 relative to each other, such as... Figure 11As shown. When the attitude locking structure is in the unlocked state, the attitude locking member 23 disengages from the attitude locking part 221, and the backrest 22 can rotate relative to the seat 21, as shown. Figures 1-10 As shown. Of course, conversely, the posture locking member 23 can be movably mounted on the backrest 22, and the posture locking part 221 can be mounted on the seat 21.

[0027] In this embodiment, such as Figure 2 , Figure 8 and Figure 11 As shown, the posture locking member 23 is rotatably mounted on the seat 21 around the pivot 24. The posture locking member 23 has a backrest hook portion 231, and the posture locking portion 221 is a protrusion extending upward from the backrest 22. When the posture locking structure is in the locked state, the backrest hook portion 231 is engaged with the protrusion, as shown... Figure 11 As shown. When the attitude locking structure is in the unlocked state, the backrest hook 231 disengages from the protrusion, as... Figure 2 As shown.

[0028] When the attitude locking structure is unlocked from the locked state, the backrest hook 231 rotates forward and upward to disengage from the protrusion, preferably the protrusion extends obliquely upward from front to back. This makes it difficult for the backrest hook 231 and the protrusion to disengage when they are engaged, allowing the attitude locking structure to remain in a stable locked state.

[0029] When basket 2 detaches from bracket 1, the posture locking structure is locked, meaning basket 2 always maintains a seated usage posture. Figure 11 As shown, this avoids the problem of directly mounting the carrier 2 forward-facing onto the car seat in any posture other than the sitting position, thus improving the safety performance of the carrier 2 when used as a child car seat. When the carrier 2 is mounted on the bracket 1, the posture locking structure is unlocked, allowing the backrest 22 and seat 21 to rotate relative to each other, thereby adjusting the usage posture of the carrier 2 and improving the comfort of using the vehicle.

[0030] The support frame 1 is equipped with a drive unit 11. When the basket 2 is installed on the support frame 1, the drive unit 11 drives the attitude locking member 23 to move relative to the seat 21, causing the attitude locking member 23 to disengage from the attitude locking part 221, and the attitude locking structure is then in the unlocked state. Figure 2 and Figure 8 As shown.

[0031] In this embodiment, the posture locking member 23 is provided with an abutment part 232. When the basket 2 is installed on the bracket 1, the drive part 11 abuts and cooperates with the abutment part 232, thereby causing the posture locking member 23 to move relative to the seat 21 and disengage the posture locking member 23 from the backrest locking part 221.

[0032] like Figure 2 and Figure 8As shown, the backrest hook 231 and the abutment part 232 are located on the same side of the pivot 24, and the abutment part 232 is located below the backrest hook 231.

[0033] The posture locking member 23 is provided with an extension 233 that extends downward from the seat 21 toward the backrest 22, and the abutment part 232 is a fixed shaft fixedly provided at the lower end of the extension 233.

[0034] In other embodiments, the basket 2 may further include a linkage movably mounted on a component in both the seat 21 and the backrest 22 where the posture locking member 23 is located. The linkage is connected to or cooperates with the posture locking member 23. When the basket 2 is mounted on the bracket 1, the drive unit 11 acts on the linkage, and the linkage acts on the posture locking member 23, causing the posture locking member 23 to move, thereby disengaging the posture locking member 23 from the posture locking part 221.

[0035] The basket 2 also includes a bracket 25, which connects the basket 2 to the support 1. In this embodiment, the bracket 25 is mounted on the seat 21; however, the bracket 25 can also be mounted on the backrest 22. The bracket 25 has a socket 251, and a stop portion 232 or a linkage extends into the socket 251. The support 1 is provided with a plug that matches the socket 251. When the basket 2 is mounted on the support 1, the plug is inserted into the socket 251, and the plug abuts against the stop portion 232 or the linkage, forming a drive portion 11. Figure 2 and Figure 8 As shown. This configuration integrates the functions of connecting the plug to the socket 251 and unlocking the attitude locking structure, which reduces the number of parts and simplifies the overall structure of the vehicle.

[0036] The basket 2 also includes a first elastic element (not shown in the figure). In this embodiment, the first elastic element is disposed between the seat 21 and the posture locking element 23. The first elastic element applies force to the posture locking element 23 to drive the posture locking element 23 to tend to move in a direction that cooperates with the posture locking part 221. That is, when the basket 2 is disengaged from the support 1, the elastic force of the first elastic element causes the posture locking element 23 to automatically rotate backward relative to the seat 21, so that the posture locking structure automatically resets to the locked state.

[0037] When the basket 2 is installed on the bracket 1, the backrest 22 and the seat 21 can rotate relative to each other in multiple positions, so that the basket 2 can be in different usage postures.

[0038] The basket 2 also includes a position locking mechanism, which is located between the seat 21 and the backrest 22. The position locking mechanism has a locked state and an unlocked state. When the position locking mechanism is in the locked state, it locks the basket 2 in various positions. When the position locking mechanism is in the unlocked state, the backrest 22 and the seat 21 can rotate relative to each other to adjust the position.

[0039] The gear shift locking structure includes a gear shift locking member 26 movably disposed on one of the seat 21 and the backrest 22, and a locking hole 211 disposed on the other. At least two locking holes 211 are spaced apart. In all usage postures, the gear shift locking structure is in a locked state, with the gear shift locking member 26 inserted into different locking holes 211, such as... Figure 12 As shown. When the gear locking structure is in the unlocked state, the gear locking member 26 disengages from all the locking holes 211.

[0040] In this embodiment, the gear locking member 26 is slidably disposed on the backrest 22 in the left and right direction, and the locking hole 211 is disposed on the seat 21.

[0041] Basket 2 also includes a gear unlocking mechanism. When the gear locking mechanism is in the locked state, operating the gear unlocking mechanism can unlock the gear locking mechanism, thereby adjusting the gear position of Basket 2.

[0042] like Figure 12 and Figure 16 As shown, the gear unlocking structure includes a gear operating component 271 and a connecting component 272. The gear operating component 271 is slidably mounted on a component where a gear locking component 26 is located, either on the seat 21 or the backrest 22. One end of the connecting component 272 is connected to the gear operating component 271, and the other end is connected to the gear locking component 26. When the gear locking structure is in the locked state, operating the gear operating component 271 pulls the gear locking component 26 via the connecting component 272, causing the gear locking component 26 to slide relative to the seat 21 or the backrest 22, thereby disengaging it from the locking hole 211, and the gear locking structure is then in the unlocked state.

[0043] The gear locking structures are respectively located on the left and right sides of the seat 21 and the backrest 22. The connecting parts 272 are respectively located on the left and right sides of the gear locking parts 26, and the connecting parts 272 on the left and right sides are connected to the same gear operating part 271. In this way, when the gear operating part 271 is operated, the gear locking structures on both sides can be unlocked simultaneously.

[0044] The basket 2 also includes a second elastic element 28, the elastic force of which is used to drive the gear locking structure to reset from the unlocked state to the locked state. The second elastic element 28 can be disposed between the gear locking elements 26 on the left and right sides, or the second elastic element 28 can be disposed between the gear locking element 26 on each side and the backrest 22 respectively.

[0045] The vehicle also includes a connecting locking structure, which is located between the bracket 1 and the basket 2. The connecting locking structure has a locked state and an unlocked state. When the basket 2 is installed on the bracket 1 and the connecting locking structure is in the locked state, the relative position between the basket 2 and the bracket 1 is locked by the connecting locking structure, preventing the basket 2 from being removed from the bracket 1. At this time, the vehicle can be used as a stroller. When the connecting locking structure is in the unlocked state, the basket 2 can be removed from the bracket 1. The basket 2 can be used alone or installed in a car seat as a child car seat.

[0046] When the seat 21 and backrest 22 form a first angle, i.e., when the carrier 2 is in a sitting position, the locking mechanism can switch between a locked and unlocked state, allowing the carrier 2 to be unlocked and detached from the bracket 1. When the angle between the backrest 22 and seat 21 is greater than the first angle, i.e., when the carrier 2 is in a reclining, semi-reclining, or other posture, the locking mechanism remains locked and cannot be unlocked, preventing the carrier 2 from being detached from the bracket 1. This prevents the carrier 2 from being detached from the bracket 1 and directly installed in a car seat when used in postures other than the sitting position, thus improving the safety performance of the carrier 2 when used as a child car seat.

[0047] like Figure 3 , Figure 4 , Figure 15 and Figure 17 As shown, the connection locking structure includes a connection locking member 31 movably mounted on the basket 2 and a bracket locking part 32 fixedly mounted on the bracket 1. When the connection locking structure is in the locked state, the connection locking member 31 cooperates with the bracket locking part 32, as shown... Figure 3 As shown. When the connection locking structure is in the unlocked state, the engagement between the connection locking member 31 and the bracket locking part 32 is disengaged, as... Figure 4 As shown.

[0048] In this embodiment, the connecting locking member 31 is rotatably disposed within the socket 251. The connecting locking member 31 is provided with a bracket hook 311, and the bracket locking part 32 is fixedly disposed on the plug. When the connecting locking structure is in the locked state, the bracket hook 311 engages with the bracket locking part 32, such as... Figure 3 As shown. When the connection locking structure is in the unlocked state, the bracket hook 311 disengages from the bracket locking part 32, as... Figure 4 As shown.

[0049] The vehicle also includes a connection unlocking structure, which is used to unlock the connection locking structure from the locked state.

[0050] The connection unlocking structure includes a connection operating component 41 and an unlocking component 42. The connection operating component 41 is movably mounted on the basket 2, and the unlocking component 42 is also movably mounted on the basket 2. One end of the unlocking component 42 is connected to the connection locking component 31.

[0051] In this embodiment, the unlocking member 42 includes at least one deformable segment 421 made of a soft material. When a first angle is formed between the seat 21 and the backrest 22, i.e., when the basket 2 is in a seated position, the deformable segment 421 is in a tensioned state, such as... Figure 5 and Figure 6 As shown. When the connecting locking structure is in the locked state and the connecting operating member 41 is operated, tension is generated in the deformable section 421, which pulls the connecting locking member 31 through the unlocking member 42, causing the connecting locking member 31 to rotate relative to the bracket 25, thereby disengaging from the locking part 32 of the bracket, and the connecting locking structure is in the unlocked state. At this time, the basket 2 can be removed from the bracket 1.

[0052] When the angle formed between the backrest 22 and the seat 21 is greater than the first angle, i.e., when the basket 2 is in a reclining, semi-reclining, or other usage posture, the deformable section 421 is in a relaxed state. At this time, when the connecting locking structure operates the connecting operating member 41 in the locked state, because the deformable section 421 is in a relaxed state, such as... Figure 7 and Figure 8 As shown, no tension is generated inside, the unlocking part 42 cannot pull the connecting locking part 31, the connecting locking part 31 remains stationary, and the connecting locking structure remains locked and cannot be unlocked.

[0053] Specifically, in this embodiment, the usage posture of the basket 2 is adjusted by rotating the backrest 22 relative to the seat 21. The backrest 22 is provided with a mating part 222. When a first angle is formed between the seat 21 and the backrest 22, i.e., when the basket 2 is in a seated usage posture, the mating part 222 engages with the deformable section 421. The supporting effect of the mating part 222 keeps the deformable section 421 in a tensioned state, such as... Figure 5 and Figure 6 As shown. When the angle formed between the backrest 22 and the seat 21 is greater than the first angle, that is, when the basket 2 is in a reclining, semi-reclining, or other usage posture, the mating part 222 moves away from the deformable section 421, and the deformable section 421 loses support and is in a relaxed state, such as... Figure 9 and Figure 10 As shown.

[0054] The mating part 222 is located at one end of the backrest 22 near the seat 21. The mating part 222 has a downwardly convex arc surface. When the seat 21 and the backrest 22 form a first angle, that is, when the basket 2 is in a seated use position, the deformable section 421 presses against this arc surface. Figure 5 and Figure 6As shown. In this way, when the connecting locking structure operates the connecting operating member 41 in the locked state, the deformable section 421 moves along the arc surface, which reduces the frictional resistance of the deformable section 421 during movement, thereby reducing the wear of the deformable section 421 and improving its service life.

[0055] In this embodiment, the connecting operating member 41 is slidably disposed at the rear of the backrest 22.

[0056] When the use posture of the basket 2 is adjusted by rotating the seat 21 relative to the backrest 22, the mating part 222 and the connecting operation part 41 are both provided on the seat 21.

[0057] In this embodiment, the unlocking component 42 is made entirely of soft material.

[0058] In other embodiments, the unlocking member 42 further includes a first rod connected to the connecting operating member 41 and a second rod connected to the connecting locking member 31, with the two ends of the deformable segment 421 connected to the first rod and the second rod, respectively.

[0059] The carrier also includes a third elastic element (not shown in the figure), the elastic force of which is used to drive the connecting locking structure from the unlocked state to the locked state. The third elastic element may be disposed between the connecting locking member 31 and the bracket 25.

[0060] The connecting locking structure is respectively set on the left and right sides of the bracket 1 and the basket 2. The unlocking part 42 is respectively set on the left and right sides of the connecting locking part 31. The unlocking parts 42 on the left and right sides are connected to the same connecting operation part 41. When the basket 2 is in a seated position and the connecting operation part 41 is operated, the posture locking structures on both sides can be unlocked at the same time.

[0061] The support frame 1 includes a base frame and a wheel assembly mounted on the base frame. The support frame 1 may also include a push rod 12 connected to the base frame, and a plug may be mounted on the push rod 12 or the base frame. The basket 2 may be provided with a handle for lifting the basket 2.

[0062] Alternatively, the support frame 1 may not be equipped with the push rod 12. When the vehicle is used as a trolley, the handle of the basket 2 can be used as the push rod. In this case, the plug is located on the base frame.

[0063] Example 2 In this embodiment, the connection unlocking structure is different from that in embodiment 1.

[0064] Specifically, the connecting operation member 41 is provided with a first mating member, and the unlocking member 42 is provided with a second mating member. When a first angle is formed between the seat 21 and the backrest 22, i.e., when the basket 2 is in a seated position, the first and second mating members engage. Thus, when the connecting operation member 41 is activated, the first and second mating members interact, causing the unlocking member 42 to activate. This causes the connecting locking member 31 to disengage from the bracket locking part 32, thereby unlocking the connecting locking structure. For example, the first mating part can be a plug-in component on the connecting operation member 41, and the second mating member can be a slot on the unlocking member 42. When the first angle is formed between the seat 21 and the backrest 22, the plug-in component is inserted into the slot.

[0065] When the angle formed between the backrest 22 and the seat 21 is greater than the first angle, that is, when the basket 2 is in a reclining, semi-reclining or other usage posture, the first and second mating parts disengage, such as the plug-in part disengaging from the slot. As a result, when the connecting operation part 41 is activated, the unlocking part 42 does not activate, the connecting locking part 31 remains stationary, and the connecting locking structure remains locked and cannot be unlocked.

[0066] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
