Description

Technical Field

[0001] This application relates to the field of children's products technology, and in particular to a baby carrier and a child vehicle. Background Technology

[0002] Some baby carriers are multifunctional, not only serving as a carrying basket and a handcarry, but also being able to be mounted on strollers and other child vehicles for pushing. These multifunctional baby carriers typically have handles that can rotate and extend to meet the different needs of both carrying and pushing modes.

[0003] In practice, it has been found that the aforementioned rotatable and retractable handle is easily rotated by mistake, posing a safety hazard. Summary of the Invention

[0004] One of the technical problems this application aims to solve is: improving the safety of using baskets.

[0005] To address the aforementioned technical problems, this application provides a carrying basket, comprising:

[0006] ontology;

[0007] The handle includes a first rod and a second rod, the first rod being slidably connected to the second rod to move relative to the second rod between a retracted position and an extended position from bottom to top, the second rod having a rotary joint and being rotatably connected to the body via the rotary joint so that the handle can rotate relative to the body;

[0008] A rotation control mechanism, movably connected to the second rod, includes a rotation locking member and an unlocking member. The rotation locking member locks the rotation joint and the body in a locked position to restrict the rotation of the rotation joint relative to the body. When operated, the unlocking member drives the rotation locking member from the locked position to the unlocked position to release the rotation locking member from locking the rotation joint and the body.

[0009] The safety mechanism is movably connected to the second lever and includes a first safety element. The first safety element locks the unlocking element in a first position to prevent the unlocking element from being operated, and the first safety element can move from the first position to the second position when the first lever moves to the retracted position to release the lock on the unlocking element.

[0010] In some embodiments, the safety mechanism further includes an elastic element that applies an elastic force to the first safety element to tend toward a first position; and / or, the safety mechanism further includes a second safety element that is movable between a third position and a fourth position. When in the third position, the second safety element locks the first lever, which is in the retracted position, to the second lever. When in the fourth position, the second safety element releases the lock on the first lever. The second safety element moves from the fourth position to the third position as the handle rotates from a preset angle position toward an increasing angle.

[0011] In some embodiments, the second safety element is rotatably connected to the second rod to rotate between a third position and a fourth position; and / or, the safety mechanism includes a second safety element and an elastic element that applies an elastic force to the second safety element to tend toward the fourth position.

[0012] In some embodiments, an elastic element is disposed between the first and second safety elements and applies torques in opposite directions to the first and second safety elements to cause the first safety element to tend toward a first position and the second safety element to tend toward a fourth position.

[0013] In some embodiments, a second safety element is disposed within a second rod, a first rod has a first hole, and a second rod has a second hole. When in a third position, the second safety element is inserted into the first hole through the second hole to lock the first rod in the retracted position onto the second rod; and / or, the body has a limiting groove, and when in a fourth position, the second safety element is located in the limiting groove.

[0014] In some embodiments, the second safety element is rotatably connected to the second rod to rotate between a third position and a fourth position. The second safety element includes a first segment and a second segment with an included angle between them. In the third position, the second segment is engaged with the first hole of the first rod via a second hole on the second rod. In the fourth position, the first segment and the second segment are located in a limiting groove on the body.

[0015] In some embodiments, the second segment is smaller than the first segment in the direction of the rotation axis of the second safety element.

[0016] In some embodiments, the basket further includes a telescopic locking member that locks the first rod in a retracted position and an extended position.

[0017] In some embodiments, the unlocking member is movably disposed along the direction of movement of the first rod relative to the second rod, so as to drive the rotary locking member to move from the locked position to the unlocked position when pulled; and / or, the rotary locking member is movably disposed along the rotation axis direction of the rotary joint, so as to move between the locked position and the unlocked position.

[0018] In some embodiments, the rotation control mechanism further includes an actuator movably disposed along the rotation axis of the rotation joint and driving the connection between the unlocking member and the rotation locking member, so that when the unlocking member is pulled, the rotation locking member is driven to move from the locked position to the unlocked position by moving along the rotation axis of the rotation joint in a direction away from the rotation joint.

[0019] In some embodiments, the actuator is rotatably connected to the rotary joint and rotates relative to the rotary joint when the unlocking member is pulled. One of the actuator and the rotary joint has a protrusion, and the other has a groove. Both the protrusion and the groove have inclined surfaces, and the inclined surfaces of the protrusion and the groove cooperate to cause the actuator to drive the rotary locking member to move away from the rotary joint along the rotation axis direction of the rotary joint during the rotation of the actuator relative to the rotary joint; and / or, the rotation control mechanism further includes a linkage member that drives the unlocking member and the actuator to move away from the rotary joint along the rotation axis direction of the rotary joint when the unlocking member is pulled.

[0020] In some embodiments, the linkage includes a pull cord, which connects to an unlocking element and an actuator.

[0021] In some embodiments, the first insurance element is constructed as at least one of the following:

[0022] Driven by the first lever, the first safety component moves from the first position to the second position;

[0023] The first safety element is rotatably connected to the second rod to rotate between a first position and a second position;

[0024] The first safety component locks the unlocking component by engaging with it.

[0025] In some embodiments, the first safety component includes a hook, and the unlocking component has a slot, with the hook engaging with the slot to achieve engagement between the first safety component and the unlocking component.

[0026] In some embodiments, the first safety element is rotatably connected to the second rod and further includes a rotating arm connected to a hook and located on both sides of the rotation center of the first safety element. During the process of the first rod moving from the extended position to the retracted position, the first safety element is driven to rotate from the first position to the second position by applying a force to the rotating arm.

[0027] Additionally, this application provides a child vehicle that includes a vehicle body and a basket according to any embodiment.

[0028] By further incorporating a safety mechanism including a first safety element in the basket, and configuring the first safety element to control the unlocking element to be operated only when the first lever moves to the retracted position, the accidental operation of the unlocking element when the handle is not in the retracted position can be effectively prevented. This effectively solves the safety problem caused by accidental operation of the unlocking element and accidental rotation of the handle, thus effectively improving the safety of using the basket.

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0050] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0051] In the description of this application, it should be understood that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.

[0052] In this application, unless otherwise stated, “multiple” means at least two, that is, including cases of two and at least three.

[0053] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0054] To improve the safety of using a baby carrier, this application provides a baby carrier and a child vehicle.

[0055] Figures 1-10 The basket and child carrier of this application are illustrated by way of example.

[0056] See Figures 1-10 In this application, the baby carrier 10 can be used as a baby carrier to be carried, or it can be installed on the body 20 of a child vehicle 100 such as a stroller to be pushed.

[0057] In some embodiments, the carrier 10 is detachably mounted on the vehicle body 20. Thus, the carrier 10 can be used with the vehicle body 20 or separately for independent use. When the carrier 10 is mounted on the vehicle body 20, it serves as the seat of a stroller for pushing and pushing. When the carrier 10 is separated from the vehicle body 20, it functions as a carrying basket, which can be lifted for easy transfer and transport. For example, the carrier 10 can be detached from the stroller and carried into a car for use as a car seat.

[0058] In other embodiments, the vehicle body 20 is foldable. This allows the carrier 10 to function as both a carrier and a seat in the child vehicle 100. For example, when used as a stroller seat, the vehicle body 20 can be unfolded to contact the ground, enabling the vehicle to move and meet pushing requirements; while when used as a carrier, the vehicle body 20 can be folded to minimize its overall size and facilitate carrying. With the vehicle body 20 foldable, the carrier 10 can be detachably or non-detachably connected to the vehicle body 20, satisfying the needs of different modes such as carrier, car seat, and stroller.

[0059] The basket 10 includes a body 1 and a handle 2. The body 1 has a seating space for a passenger. The handle 2 includes a first rod 21 and a second rod 22. The first rod 21 is slidably connected to the second rod 22, allowing it to move relative to the second rod 22 between a retracted position and an extended position from bottom to top. The second rod 22 has a rotating joint 24 and is rotatably connected to the body 1 via the rotating joint 24, allowing the handle 2 to rotate relative to the body 1. Thus, the handle 2 is rotatably and retractably mounted on the body 1, enabling it to be used as both a push handle and a lift handle, thereby allowing the basket 10 to be both pushed and lifted.

[0060] Typically, the angle of the handle 2 differs between the two different usage modes: pushing and lifting. For example, in some embodiments, see... Figure 1 and Figure 2 In push mode, the handle 2 tilts forward (or backward) at a small angle, that is, the angle between the extension direction of the handle 2 (or the plane on which the handle 2 is located) and the forward (or backward) direction of the body 1 is a preset angle. In the forward (or backward) pushing mode, the handle 2 extends vertically or tilts forward (or backward) at a large angle, that is, the angle between the extension / retraction direction of the handle 2 (or the plane on which the handle 2 is located) and the forward (or backward) direction of the body 1 is greater than a preset angle. It is understandable that the "front" and "back" here are based on the main body 1. Generally, the side where the backrest 13 of the main body 1 is located is the "back", while the other side of the main body 1 opposite to the backrest 13 is the "front".

[0061] Preset angle Generally less than 90°, within the preset angle. At this time, the push is relatively comfortable and can achieve a better push experience. Therefore, in the push mode, it is generally required to lock 2 at the preset angle. corresponding preset angle This can also be referred to as the pushing angle. In the lifting mode, the angle of handle 2 is greater than the preset angle. This makes it easier to lift and provides a better lifting experience. For example, in some cases, when users lift vertically, the angle of handle 2 in lifting mode (which can be called the lifting angle) is 90°, which is more in line with ergonomics and the user's lifting habits.

[0062] It is evident that the pushing mode and the lifting mode have different requirements for the angle position of the handle 2. Therefore, the handle 2 needs to rotate relative to the body 1 to switch between the pushing angle and the lifting angle to meet the angle position requirements of these two different modes.

[0063] However, the push mode and the lift mode have different requirements not only for the angle of the handle 2, but also for whether the handle 2 can rotate, whether it can be extended or retracted, and the position of extension or retraction. For example, generally, it is desirable that in the lift mode, the handle 2 can rotate, but the first rod 21 is locked in the retracted position and cannot be extended. This can meet the needs of lifting at different angles and can be used when the handle 2 is shorter, making it more convenient and effortless. It can also prevent the handle 2 from accidentally extending during lifting, thus avoiding safety issues such as startling or injuring children. As another example, generally, it is desirable that in the push mode, the handle 2 can be extended or retracted, and can only rotate when the first rod 21 reaches the retracted position. It cannot rotate when the first rod 21 is not in the retracted position. This allows the length of the handle 2 to be changed during normal push mode to meet the push needs of users of different heights. Moreover, when the first rod 21 reaches the retracted position (indicating that the user may be preparing to switch from push mode to lift mode), the angle of the handle 2 can be changed, causing the handle 2 to rotate towards the lift angle.

[0064] It is evident that the push and lift modes have different requirements for the rotation and extension of the handle 2. The rotation and extension need to be controlled so that the handle 2 only rotates when the first lever 21 is in the retracted position (corresponding to the lifting condition and the condition of switching from the push mode to the lifting mode), and only extends in the push mode.

[0065] To control the extension and rotation of handle 2, see [link / reference]. Figures 3-4 Generally, the basket 10 includes not only the body 1 and the handle 2, but also the telescopic control mechanism 3 and the rotation control mechanism 4.

[0066] The telescopic control mechanism 3 is used to control the extension and retraction of the handle 2. (See also...) Figures 3-4 In some embodiments, the telescopic control mechanism 3 includes a telescopic locking member 31 that locks the first rod 21 in the retracted position and the extended position.

[0067] The retracted position and the extended position are the two telescopic positions of the first rod 21. The retracted position is the position where the first rod 21 is retracted relative to the second rod 22, and the extended position is the position where the first rod 21 is extended relative to the second rod 22. The two are arranged sequentially along the extension direction of the first rod 21 (i.e., the direction away from the rotating joint 24, which can also be called the bottom-up direction). Therefore, when the telescopic locking member 31 locks the first rod 21 in the extended position, the handle 2 can be locked at a longer length. When the first rod 21 is locked in the retracted position, the handle 2 can be locked at a shorter length. In particular, when the retracted position is the telescopic position of the first rod 21 that is closest to the rotating joint 24 among the multiple telescopic positions, locking the first rod 21 in the retracted position means locking the handle 2 at the shortest length.

[0068] See Figure 4 In some embodiments, the telescopic locking member 31 is disposed in the first rod 21 and located at a lower position. A first reset member 32 (e.g., spring 34) is provided between the telescopic locking member 31 and the inner wall of the first rod 21. The first reset member 32 applies force to the telescopic locking member 31 to extend the telescopic locking member 31 outward from the first rod 21 and engage with two locking holes (not shown in the figure) on the second rod 22 that correspond to the retracted position and the extended position, respectively, thereby achieving the locking of the first rod 21 in the retracted position and the extended position.

[0069] To facilitate the movement of the first rod 21 between different telescopic positions, see [link / reference] Figure 4In some embodiments, the telescopic control mechanism 3 includes not only the telescopic locking member 31, but also the release member 33. The release member 33 is used to release the locking effect of the telescopic locking member 31 on the first rod 21 at different telescopic positions, so that the first rod 21 can move between different telescopic positions and flexibly adjust the length of the handle 2.

[0070] As one example of the release member 33, the release member 33 includes an operating member (not shown) and a traction member (not illustrated). The operating member is located on the first rod 21. The traction member is disposed in the first rod 21, with one end connected to the operating member and the other end connected to the telescopic locking member 31. The operating member is configured to pull the telescopic locking member 31 via the traction member when receiving an operating force, so that the telescopic locking member 31 overcomes the elastic force of the first reset member 32 and disengages from the locking hole (e.g., the first locking hole corresponding to the retracted position or the second locking hole corresponding to the extended position), thereby releasing the telescopic locking member 31 from locking the first rod 21.

[0071] The traction component can be a steel wire rope or other flexible component that provides tension. The operating component can be a button. See also Figure 4 In some embodiments, the operating element is located on the upper part of the first rod 21 (i.e., the crossbeam 211 that can be pushed).

[0072] The release mechanism 33, in conjunction with the operating mechanism, may further include an upper cover (not shown), a lower cover (not shown), and a pull member (not shown). The crossbeam 211 of the first rod 21 may have a through slot so that the upper and lower covers surround the first rod 21 and engage with each other through the slot. The pull member may be disposed within the crossbeam 211 and slide on the surface of the lower cover.

[0073] Two pull members can be provided to cooperate with the operating member. The operating member is installed in the through hole of the upper cover and has two first wedge-shaped portions, which can respectively cooperate with the second wedge-shaped portions on the two pull members through the wedge-shaped surfaces, so that when the operating member is pressed, the two pull members slide towards each other. The ends of the traction members on both sides are connected to the two pull members, so that as the two pull members slide towards each other, the telescopic locking members 31 on both sides overcome the elastic force of the first reset member 32 and disengage from the locking hole.

[0074] Of course, the telescopic locking member 31 and the unlocking member 33 can also adopt other structural forms, as long as they can control the locking and unlocking of the first rod 21 in different telescopic positions.

[0075] The rotation control mechanism 4 is used to control the rotation of the handle 2. (See also...) Figures 3-4In some embodiments, the rotation control mechanism 4 is movably connected to the second rod 22 and includes a rotation locking member 41 and an unlocking member 43. The rotation locking member 41 locks the rotation joint 24 and the body 1 in the locked position to restrict the rotation of the rotation joint 24 relative to the body 1. When the unlocking member 43 is operated, it drives the rotation locking member 41 from the locked position to the unlocked position to release the rotation locking member 41 from locking the rotation joint 24 and the body 1.

[0076] Based on the above settings, the rotation control mechanism 4 can be rotated by the rotation locking member 41, so that the handle 2 cannot be rotated, and the rotation locking member 41 can be released by the unlocking member 43, so that the handle 2 can be rotated.

[0077] The unlocking component 43 drives the rotating locking component 41 from the locked position to the unlocked position when it is operated, that is, when it receives the user's operating force, so as to realize the rotating unlocking function. Therefore, it can control the handle 2 to rotate only when needed, thereby improving the safety of using the basket 10.

[0078] However, in practice, it has been found that the unlocking component 43 may be misoperated, causing the basket 10 to rotate unexpectedly and leading to safety issues. For example, as mentioned earlier, when the basket 10 is in push mode, that is, when the handle 2 is at a preset angle... It is not desirable for the handle 2 to rotate before the first lever 21 is in the retracted position. However, in actual use, the user may operate the unlocking part 43 and rotate the handle 2 before the first lever 21 is in the retracted position, which may cause the basket 10 to tip over and other safety issues, affecting the safety of the basket 10.

[0079] In related technologies, although some improvements have been made to the rotation safety of the handle 2, the corresponding improvements are usually made by adding a rotation locking mechanism in addition to the rotation locking member 41 to lock the rotation joint 24 and the body 1. This allows for double locking of the rotation joint 24 and the body 1 using the rotation locking member 41 and the rotation locking mechanism, with the rotation locking mechanism supplementing the rotation locking member 41, thereby improving the rotation safety of the handle 2.

[0080] However, while the aforementioned method of adding a rotation locking mechanism to lock the rotating joint 24 and the main body 1 can improve the rotation safety of the handle 2 to a certain extent, it still cannot solve the safety problem caused by the accidental operation of the unlocking part 43 and the accidental rotation of the handle 2. This is because the rotation locking mechanism does not prevent the unlocking part 43 from being accidentally operated. Even with the rotation locking mechanism, the unlocking part 43 can still be operated arbitrarily. In this case, if the user, due to unfamiliarity or panic, mistakenly operates the unlocking part 43 before the handle 2 is in the retracted position, the user will be able to operate the unlocking part 43 successfully. Once the unlocking part 43 is successfully operated, the user will assume that the handle 2 can be rotated. Therefore, the user may immediately start to rotate the handle 2 without considering whether the handle 2 is in the retracted position or whether the conditions for rotation are met. In other words, the user may force the handle 2 to rotate before it is in the retracted position and before the conditions for rotation are met, ultimately damaging the rotation locking mechanism, causing the handle 2 to be accidentally rotated, and triggering a safety problem.

[0081] It is evident that although setting up a rotation locking mechanism and a rotation locking component together to lock the rotation joint 24 and the main body 1 can improve the safety of the basket 10 to a certain extent, it is still difficult to solve the safety problems caused by the accidental operation of the unlocking component 43 and the accidental rotation of the handle 2.

[0082] Therefore, effectively solving the security problems caused by the accidental operation of the unlocking component 43 is a difficult problem, and the security of the basket 10 still needs to be improved.

[0083] In view of the above situation, this application improves the structure of the basket 10.

[0084] See Figures 1-10 In this application, the basket 10 includes not only the body 1, the handle 2, and the rotation control mechanism 4, but also a safety mechanism 5. The safety mechanism 5 is movably connected to the second lever 22 and includes a first safety member 51. The first safety member 51 locks the unlocking member 43 in a first position to prevent the unlocking member 43 from being operated, and the first safety member 51 can move from the first position to the second position when the first lever 21 moves to the retracted position to release the lock on the unlocking member 43.

[0085] In the above scheme, the unlocking component 43 is equipped with a first safety component 51. The first safety component 51 controls whether the unlocking component 43 can be unlocked, and controls that the unlocking component 43 can only be unlocked and operated when the first lever 21 reaches the retracted position. This makes the unlocking component 43 no longer arbitrarily operable, but restricted. Only when the first lever 21 moves to the retracted position will the first safety component 51 release the lock on the unlocking component 43, allowing the unlocking component 43 to be operated and release the lock on the rotation locking component 41, so that the handle 2 can be rotated. If the first lever 21 has not reached the retracted position, the unlocking component 43 cannot be operated, and the handle 2 cannot be rotated. In this case, if the first lever 21 is not in the retracted position, even if the user operates the unlocking component 43, the operation will not be successful. If successful, the unlocking component 43 will not release the lock on the rotation locking component 41, but will remain locked, preventing the handle 2 from being rotated. Therefore, it can effectively prevent the unlocking component 43 from being accidentally operated, so that the handle 2 can only be rotated when the first lever 21 is moved to the retracted position. In this way, the handle 2 can be rotated when the first lever 21 is in the retracted position, thereby meeting the needs of the basket 10 to switch from the push mode to the lift mode and the needs of the basket 10 to adjust the lifting angle in the lift mode (both of which require the handle 2 to rotate only when the first lever 21 is in the retracted position). Furthermore, the handle 2 cannot be rotated when the first lever 21 is not in the retracted position, thereby preventing the handle 2 from accidentally rotating when the first lever 21 is not in the retracted position and causing safety problems.

[0086] It is evident that by further providing a safety mechanism 5 including a first safety element 51 in the basket 10, and configuring the first safety element 51 to control the unlocking element 43 to be operated only when the first lever 21 moves to the retracted position, the rotation requirements of the handle 2 under the conditions of pushing, lifting, and switching between pushing and lifting can be effectively met. At the same time, the unlocking element 43 can be effectively prevented from being accidentally operated when the handle 2 is not in the retracted position. Therefore, the safety problem caused by the accidental operation of the unlocking element 43 and the accidental rotation of the handle 2 can be effectively solved, thereby effectively improving the safety of the basket 10.

[0087] To facilitate the control of the first safety element 51, the unlocking element 43 can only be operated when the first lever 21 moves to the retracted position. See below. Figure 4 and Figure 10In some embodiments, the first safety element 51 moves from a first position to a second position under the drive of the first lever 21. In this way, the first safety element 51 can be driven by the first lever 21 to move from the first position to the second position during the movement of the first lever 21 relative to the second lever 22 toward the retracted position. When the first lever 21 moves to the retracted position relative to the second lever 22, it moves to the second position, releasing the lock on the unlocking element 43, so that the unlocking element 43 can be operated and the handle 2 can be rotated. In the corresponding process, since the first lever 21 can drive the first safety element 51 to move from the first position that locks the unlocking element 43 to the second position that unlocks the unlocking element 43 during the movement toward the retracted position, the first safety element 51 can automatically move from the first position to the second position as the first lever 21 moves toward the retracted position. There is no need to separately control the first safety element 51 to move toward the second position. Therefore, it is simpler and more convenient, and it is more conducive to using the first safety element 51 to control the unlocking element 43 to be operated only when the first lever 21 moves to the retracted position. This can more reliably prevent the unlocking element 43 from being operated by mistake and more effectively improve the safety of the basket 10.

[0088] In the foregoing embodiments, the movement of the first safety element 51 between the first position and the second position is not limited, and can be movement and / or rotation. For example, see... Figure 4 and Figure 10 The first safety element 51 is rotatably connected to the second lever 22, allowing it to rotate between a first position and a second position. In this case, the movement of the first safety element 51 between the first and second positions is rotational; that is, the first safety element 51 moves between the first and second positions by rotation. This makes it easier for the first safety element 51 to reliably control the unlocking element 43 to be operated only when the first lever 21 moves to the retracted position. In particular, it makes it easier for the first safety element 51 to move from the first position to the second position under the drive of the first lever 21, reliably controlling the unlocking element 43 to be operated only when the first lever 21 moves to the retracted position.

[0089] Furthermore, in the aforementioned embodiments, the first locking element 51 and the unlocking element 43 can be coupled in various ways to achieve the locking of the unlocking element 43 by the first locking element 51. As one example, see... Figure 4 and Figure 10The first safety element 51 engages with the unlocking element 43 to lock the unlocking element 43. At this time, the first safety element 51 and the unlocking element 43 are locked together by a snap-fit ​​mechanism. This snap-fit ​​locking method is simple, convenient, and reliable. It allows for easy and reliable locking of the unlocking element 43 when needed, effectively preventing accidental rotation of the handle 2. Conversely, it allows for easy release of the snap-fit ​​mechanism when needed, effectively satisfying the rotation requirements of the handle 2. Therefore, it facilitates a simpler, more convenient, and safer rotation control process.

[0090] In order to achieve the engagement between the first safety element 51 and the unlocking element 43, a hook 52 can be provided on one of the first safety element 51 and the unlocking element 43, and a corresponding slot 46 can be provided on the other. The engagement between the first safety element 51 and the unlocking element 43 can be achieved through the cooperation of the hook 52 and the slot 46.

[0091] For example, see Figure 4 and Figure 10 In some embodiments, the first safety element 51 includes a hook 52, and the unlocking element 43 has a slot 46. The hook 52 engages with the slot 46 to achieve engagement between the first safety element 51 and the unlocking element 43. In this case, the first safety element 51 has a hook 52, and the unlocking element 43 has a slot 46. Since the hook 52 is located on the first safety element 51 and moves with it, it facilitates engagement between the first safety element 51 and the unlocking element 43 in the first position for reliable locking. It also facilitates disengagement of the first safety element 51 from the unlocking element 43 when the first lever 21 moves to the retracted position, releasing the lock on the unlocking element 43. In particular, it facilitates disengagement of the first safety element 51 from the unlocking element 43 by rotation, releasing the lock on the unlocking element 43.

[0092] For example, see Figure 4 and Figure 10 In some embodiments, a first safety member 51, including a hook 52, is rotatably connected to a second rod 22, and also includes a rotating arm 53 connected to the hook 52 and located on both sides of the rotation center of the first safety member 51. During the process of the first rod 21 moving from the extended position to the retracted position, the first safety member 51 is driven to rotate from the first position to the second position by applying a force to the rotating arm 53.

[0093] Based on the above configuration, the first safety element 51 not only locks the unlocking element 43 in the first position by snapping, but also, by being driven by the first rod 21 during the process of the first rod 21 moving from the extended position to the retracted position, rotates from the first position to the second position, thereby releasing the lock on the unlocking element 43. In this case, the first safety element 51 moves between the first and second positions by rotation, and it can be easily driven by the first lever 21 through the rotating arm 53. This allows the first safety element 51 to automatically rotate from the first position to the second position as the first lever 21 moves from the extended position to the retracted position, without the need for additional control of the first safety element 51 to rotate to the second position. Moreover, the first safety element 51 is provided with a hook 52, which can easily engage or disengage with the slot 46 on the unlocking element 43 during the rotation of the first safety element 51, controlling whether the unlocking element 43 is locked. Therefore, a simpler, more convenient, and safer rotation control process can be achieved, and the handle 2 can be controlled to rotate only when the first lever 21 is in the retracted position. This is beneficial to further improve the safety of the basket 10.

[0094] As a further improvement to the foregoing embodiments, see Figure 4 The safety mechanism 5 includes not only a first safety element 51 but also an elastic element 54. The elastic element 54 applies an elastic force to the first safety element 51, causing it to tend towards a first position. Based on this, under the action of the elastic element 54, the first safety element 51 can remain in the first position under normal conditions, locking the unlocking element 43 and reliably preventing accidental operation of the unlocking element 43. Furthermore, when it is necessary to reuse the first safety element 51 to lock the unlocking element 43, the first safety element 51 can automatically return from the second position to the first position under the action of the elastic element 54, locking the unlocking element 43 again without requiring additional driving of the first safety element 51. Therefore, this further improves the locking reliability of the first safety element 51 on the unlocking element 43, simplifies the locking process of the first safety element 51 on the unlocking element 43, and achieves a simpler and more reliable locking process, thus more effectively improving the safety of the basket 10.

[0095] Furthermore, as a further improvement to the aforementioned embodiments, the safety mechanism 5 also includes a second safety member 55, which can move between a third position and a fourth position. When in the third position, the second safety member 55 locks the first lever 21, which is in the retracted position, to the second lever 22. When in the fourth position, the second safety member 55 releases the lock on the first lever 21. Moreover, as the handle 2 rotates from the preset angle position in the direction of increasing angle, the second safety member 55 moves from the fourth position to the third position.

[0096] The second safety element 55 can move from the fourth position where the first rod 21 is not locked to the third position where the first rod 21 is locked in the retracted position as the handle 2 rotates from a preset angle to an angle position larger than the preset angle. As mentioned earlier, when the handle 2 rotates from a preset angle to an angle larger than the preset angle, it means that the basket 10 is switching from the push mode to the lift mode. Therefore, a second safety element 55 is provided to lock the first rod 21 in the retracted position during the rotation of the handle 2 from the preset angle to an angle larger than the preset angle. This ensures that the first rod 21 is locked in the retracted position both during and after the basket 10 switches from the push mode to the lift mode. This effectively prevents the first rod 21 from accidentally extending during the switch and in the lift mode, thus avoiding safety issues such as startling or injuring the child. Furthermore, when the basket 10 includes the aforementioned telescopic locking element 31, the second safety element 55, together with the telescopic locking element 31, can lock the handle 2 in the retracted position when the angle of the handle 2 is greater than the preset angle. This achieves double locking of the handle 2 in the retracted position under corresponding conditions, more reliably preventing the handle 2 from accidentally extending. Therefore, the safety of using the basket 10 can be further improved.

[0097] In the above scheme, the first safety element 51 and the second safety element 55 respectively perform rotational locking and telescopic locking. Working together, they ensure that the rotation and telescopic movement of the handle 2 can only occur when necessary, thus effectively improving the safety of the basket 10. Furthermore, since the first safety element 51 reliably controls the handle 2 to rotate only when the first lever 21 is in the retracted position, the second safety element 55 does not need to perform rotational locking on the handle 2. Similarly, since the second safety element 55 reliably controls the handle 2 to prevent it from extending from the retracted position when the angle is greater than a preset angle, the first safety element 51 also does not need to perform telescopic locking on the handle 2. Therefore, the structure and control process of the first safety element 51 and the second safety element 55 are relatively simple. There is no need to add other structural components or control steps to make the first safety element 51 and the second safety element 55 have another locking function. Therefore, the overall structure is simpler, the control is more convenient, and it is beneficial to improve the safety of the basket 10 more conveniently and reliably.

[0098] In use, simply retract the first lever 21 to the retracted position, then operate the unlocking component 43, and then rotate the handle 2 in a direction greater than the preset angle. The second safety component 55 will then move from the fourth position to the third position and finally move to the third position, locking the first lever 21 in the retracted position to prevent the first lever 21 from extending unexpectedly.

[0099] It is evident that by adding a second safety element 55 on top of the first safety element 51, the safety of the basket 10 can be improved more effectively with a simpler structure.

[0100] The movement of the second safety element 55 between the third and fourth positions is not limited; it can be movement and / or rotation. For example, see... Figure 4 and Figure 10 In some embodiments, the second safety element 55 is rotatably connected to the second rod 22 to rotate between a third position and a fourth position. In this case, the movement of the second safety element 55 between the third and fourth positions is rotational; that is, the second safety element 55 moves between the third and fourth positions by rotation. Thus, the movement of the second safety element 55 is consistent with the movement of the handle 2, both being rotational. During the rotation of the handle 2 to an angle greater than a preset angle, the second safety element 55, driven by the handle 2, rotates along with the handle 2, moving from the fourth position to the third position, locking the first rod 21 in the retracted position. Therefore, it is more convenient for the second safety element 55 to limit the extension of the handle 2 when the angle of the handle 2 is greater than the preset angle, improving the safety of using the basket 10.

[0101] Furthermore, the second safety element 55 can lock the first lever 21 in the retracted position in a variety of ways. As one example, see [link to example]. Figure 4 , Figure 5 as well as Figure 10 The second safety element 55 is disposed within the second rod 22. The first rod 21 has a first hole 213, and the second rod 22 has a second hole 221. When in the third position, the second safety element 55 engages with the first hole 213 through the second hole 221 to lock the first rod 21 in the retracted position onto the second rod 22. In this manner, the second safety element 55 locks the first rod 21 in the retracted position by engaging with the first hole 213 through the second hole 221 on the second rod 22 in the third position. This method is simple, convenient, and provides a good locking effect.

[0102] See also Figure 4 , Figure 5 and Figure 10In some embodiments, the main body 1 is provided with a limiting groove 12. When in the fourth position, the second safety member 55 is located in the limiting groove 12. In this way, the second safety member 55 can be constrained by the main body 1 when in the fourth position, which helps to prevent the second safety member 55 from accidentally leaving the fourth position, and also helps to further improve the safety of the basket 10. It should be noted that although the second safety member 55 is located in the limiting groove 12 on the main body 1 in the fourth position, the second safety member 55 does not rotate and lock the main body 1 and the rotating joint 24 in the fourth position, and does not prevent the handle 2 from rotating in a direction greater than a preset angle. On the contrary, the limiting groove 12 can actually avoid the movement (especially rotation) of the second safety member 55 between the third and fourth positions, providing space for the movement (especially rotation) of the second safety member 55 between the third and fourth positions. This makes it easier for the second safety member 55 to extend, retract, lock, or unlock the handle 2.

[0103] In actual operation, when the first lever 21 retracts to the retracted position, the user operates the unlocking component 43 and rotates the handle 2 in a direction greater than a preset angle. The handle 2 then drives the second safety component 55 to move, causing it to gradually disengage from the limiting groove 12 and reach the third position, locking the first lever 21 and the second lever 22. During this process, when the second safety component 55 disengages from the limiting groove 12 and reaches the third position, it can abut against the outer surface of the joint mating part 11 of the body 1, improving the stability of the second safety component 55 in the third position and achieving a more reliable telescopic locking mechanism.

[0104] The design with a limiting groove 12 on the main body 1 is particularly suitable for situations where the second safety component 55 moves between the third and fourth positions by rotation. For example, see... Figure 4 , Figure 5 as well as Figure 10In some embodiments, the second safety element 55 is rotatably connected to the second rod 22 to rotate between a third position and a fourth position, and the second safety element 55 includes a first segment 56 and a second segment 57, with an included angle between the first segment 56 and the second segment 57 (i.e., not collinear, not located on a straight line). When in the third position, the second segment 57 is engaged in the first hole 213 on the first rod 21 via the second hole 221 on the second rod 22. When in the fourth position, the first segment 56 and the second segment 57 are located in the limiting groove 12 on the body 1. In this case, the second safety element 55 includes a first segment 56 and a second segment 57 that are angled together, and moves between a third position and a fourth position by rotation. In the third position, the second segment 57 engages with the first rod 21 and the second rod 22 to lock the first rod 21 in the retracted position. In the fourth position, the first segment 56 and the second segment 57 are embedded in the limiting groove 12 on the body 1. Thus, the second safety element 55 can easily enter and exit the limiting groove 12 and the first hole 213 of the first rod 21 and the second hole 221 of the second rod 22 by rotating with the handle 2. In both the third and fourth positions, it can be relatively stably maintained in the corresponding position. Therefore, the second safety element 55 can conveniently and reliably lock the first rod 21 in the retracted position when the handle angle is greater than the preset angle, thereby improving the reliability of the basket 10.

[0105] In the case where the second safety element 55 includes the first segment 56 and the second segment 57, to facilitate the insertion of the second safety element 55 into the first lever 21, see [reference needed]. Figure 4 and Figure 10 In some embodiments, the second segment 57 is smaller than the first segment 56 in the direction of rotation axis of the second safety element 55. In this case, the dimensions (which may be referred to as thickness) of the first segment 56 and the second segment 57 in the direction of rotation axis of the second safety element 55 are different, and the thickness of the second segment 57 is smaller than that of the first segment 56, forming a step between them. In this way, the second segment 57 is thinner, making it easier to insert into the first rod 21 and lock the first rod 21 in the retracted position.

[0106] In the case where insurance institution 5 includes a second insurance policy 55, see Figure 4In some embodiments, the safety mechanism 5 includes not only a second safety element 55 but also an elastic element 54. The elastic element 54 applies an elastic force to the second safety element 55, causing it to tend towards a fourth position. Based on this, under the action of the elastic element 54, the second safety element 55 can remain in the fourth position under normal conditions to meet the extension / retraction requirements of the first lever 21 under normal conditions. Moreover, when it is necessary to use the second safety element 55 to lock the first lever 21 in the retracted position, it is only necessary to overcome the elastic force of the elastic element 54 to move the second safety element 55 away from the fourth position and towards the third position, which is labor-saving and efficient. Furthermore, when the first lever 21 needs to extend from the retracted position, the second safety element 55 can also automatically return from the third position to the fourth position under the action of the elastic element 54, releasing the lock on the first lever 21 again without the need for additional driving of the second safety element 55. Therefore, it is beneficial to improve the reliability of the second safety element 55 in the fourth position and the convenience of returning from the third position to the fourth position, thus improving the safety of the basket 10 more conveniently and effectively.

[0107] The elastic element 54 that applies elastic force to the second safety element 55 and the elastic element 54 that applies elastic force to the first safety element 51 mentioned above can be the same to simplify the structure. For example, see Figure 4 In some embodiments, the elastic element 54 is disposed between the first safety element 51 and the second safety element 55, and applies opposite torques to the first safety element 51 and the second safety element 55, causing the first safety element 51 to tend towards a first position and the second safety element 55 to tend towards a fourth position. In this case, the elastic element 54 applying elastic force to the second safety element 55 is the same as the elastic element 54 mentioned above that applies elastic force to the first safety element 51. This single elastic element 54, disposed between the first safety element 51 and the second safety element 55, allows the first safety element 51 to rotate back to the first position and the second safety element 55 to rotate back to the fourth position by applying opposite torques to the first safety element 51 and the second safety element 55. In this case, since the first safety element 51 and the second safety element 55 can share the same elastic element 54, there is no need to provide separate elastic elements 54 for each, thus simplifying the structure.

[0108] The elastic member 54, which is disposed between the first safety member 51 and the second safety member 55 and applies reverse torque to the first safety member 51 and the second safety member 55, can be constructed as a torsion spring to conveniently apply reverse torque to the first safety member 51 and the second safety member 55 by utilizing the structural characteristics of the torsion spring.

[0109] In the foregoing embodiments, the movement of the rotating locking member 41 between the locked and unlocked positions is not limited; it can be movement and / or rotation. For example, see... Figure 3In some embodiments, the rotating locking member 41 is movably disposed along the rotation axis of the rotating joint 24 to move between a locked position and an unlocked position. In this case, the movement of the rotating locking member 41 between the locked and unlocked positions is a movement, and it is a movement along the rotation axis of the rotating joint 24. Therefore, the unlocking member 43 only needs to drive the rotating locking member 41 to move along the rotation axis of the rotating joint 24 to switch the rotating locking member 41 between the locked and unlocked positions, thus controlling whether the rotating locking member 41 is rotating and locked, which is simple and convenient.

[0110] In the foregoing embodiments, the unlocking member 43 can be constructed in various structural forms such as a button or a handle, and correspondingly, the unlocking member 43 can be operated in various ways such as pressing or pulling.

[0111] For example, see Figures 3-10 In some embodiments, the unlocking member 43 is movably disposed along the moving direction of the first rod 21 relative to the second rod 22, so as to drive the rotation locking member 41 from the locked position to the unlocked position when pulled. In this case, the unlocking member 43 is constructed as a handle, and its operation is by pulling, specifically by pulling along the extension direction of the first rod 21. In this way, the user only needs to pull the unlocking member 43, which is unlocked by the first safety member 51, to complete the operation of the unlocking member 43 and release the lock of the rotation locking member 41, which is simple and convenient. In particular, this pulling method along the extension direction of the first rod 21 is more ergonomic than the pressing method, making it easier for the user to apply force and operate the unlocking member 43 more efficiently and effortlessly to release the rotation lock. Moreover, this pulling method along the extension direction of the first rod 21 is less likely to be operated by children than the pressing method, which is more conducive to preventing children from accidentally operating the unlocking member 43. Therefore, it is beneficial to more reliably prevent the handle 2 from turning accidentally and to more reliably improve the safety of the basket 10.

[0112] When the unlocking member 43 is pulled along the extension direction of the first rod 21, in order to facilitate the unlocking member 43 in controlling whether the rotating locking member 41 is unlocked, see [reference needed]. Figures 3-10In some embodiments, the rotation control mechanism 4 further includes an actuator 48, which is movably disposed along the rotation axis of the rotation joint 24 and drives the unlocking member 43 and the rotation locking member 41. When the unlocking member 43 is pulled, the rotation locking member 41 is driven to move away from the rotation joint 24 along the rotation axis of the rotation joint 24, thereby moving the rotation locking member 41 from the locked position to the unlocked position. In this case, the actuator 48 can convert the movement of the unlocking member 43 along the extension direction of the first rod 21 into the movement of the rotation locking member 41 away from the rotation joint 24 along the rotation axis of the rotation joint 24. This allows the rotation locking member 41 to disengage from the rotation joint 24 by moving away from the rotation joint 24 along the rotation axis of the rotation joint 24, thereby releasing the lock on the rotation joint 24 and the body 1 and realizing the rotation unlocking function, which is simple and convenient.

[0113] Specifically, see [link to relevant documentation] Figures 3-10 In some embodiments, the actuator 48 is rotatably connected to the rotating joint 24 and rotates relative to the rotating joint 24 when the unlocking member 43 is pulled. One of the actuator 48 and the rotating joint 24 has a protrusion 28, and the other has a groove 49. Both the protrusion 28 and the groove 49 have inclined surfaces 281, and these inclined surfaces 281 engage, causing the actuator 48 to move the rotating locking member 41 away from the rotating joint 24 along the rotation axis of the rotating joint 24 during its rotation. In this case, the actuator 48 converts the movement of the unlocking member 43 along the extension direction of the first rod 21 into the movement of the rotating locking member 41 away from the rotating joint 24 by rotating while simultaneously moving away from the rotating joint 24 along its rotation axis. Specifically, the actuator 48 rotates when the unlocking member 43 is pulled. During rotation, based on the engagement of the protrusion 28 and the inclined surface 281 of the groove 49, it moves away from the rotation axis of the rotation joint 24, thereby driving the rotation locking member 41 to move away from the rotation axis of the rotation joint 24, causing the rotation locking member 41 to disengage from the rotation joint 24 and release the lock on the rotation joint 24 and the body 1, thus realizing the rotation unlocking function. Because the actuator 48 can rotate while simultaneously driving the rotation locking member 41 to move away from the rotation axis of the rotation joint 24, thanks to the engagement of the protrusion 28 and the inclined surface 281 of the groove 49, it is simple, convenient, and has a compact structure.

[0114] For ease of unlocking component 43 driving actuator 48, see [link / reference] Figures 3-10In some embodiments, the rotation control mechanism 4 further includes a linkage 47, which drives the unlocking member 43 and the actuator 48 to move away from the rotation joint 24 along the rotation axis direction of the rotation joint 24 when the unlocking member 43 is pulled. Providing a linkage 47 to drive the unlocking member 43 and the actuator 48 makes it easier to convert the movement of the unlocking member 43 along the extension direction of the first rod 21 into the movement of the actuator 48 along the rotation axis direction of the rotation joint 24 away from the rotation joint 24. In particular, it makes it easier to convert the movement of the unlocking member 43 along the extension direction of the first rod 21 into the simultaneous rotation of the actuator 48 and its movement along the rotation axis direction of the rotation joint 24 away from the rotation joint 24.

[0115] Specifically, see Figure 7 In some embodiments, the linkage 47 includes a pull rope 471, which connects the unlocking member 43 and the actuating member 48. Since the pull rope 471 is a flexible component, it can taut to transmit force when the unlocking member 43 is pulled and relax when the unlocking member 43 is released. Therefore, it better suits the motion characteristics of the unlocking member 43 and the actuating member 48, facilitating power transmission between them, and occupies less space, thus making the structure simpler and more compact.

[0116] The following will provide further details. Figures 1-10 The example shown.

[0117] like Figures 1-10 As shown, in this embodiment, the child vehicle 100 is a stroller, which includes a carrier 10 and a vehicle body 20. The vehicle body 20 has wheels, and the carrier 10 is detachably mounted on the vehicle body 20, so that, on the one hand, the carrier 10 can be removed from the vehicle body 20 and used as a carrier, or installed in a car and used as a car seat; on the other hand, the carrier 10 can also be mounted on the vehicle body 20 and used together with the vehicle body 20 to achieve pushing on the ground.

[0118] The baby carrier 10 is for children to ride in and for users to carry or push. In this embodiment, the baby carrier 10 includes a body 1, a handle 2, a telescopic control mechanism 3, a rotation control mechanism 4, and a safety mechanism 5.

[0119] The main body 1 has a seating space for children. It also includes a backrest 13 and a joint-fitting part 11. The backrest 13 provides support for the passenger in the seating space. When the passenger leans against the backrest 13, their face is away from it. Therefore, the front and back are defined as follows: the side with the backrest 13 is considered the rear, and the side of the main body 1 opposite the backrest 13 is considered the front. The joint-fitting part 11 engages with the rotating joint 24 of the handle 2, enabling a rotatable connection between the handle 2 and the main body 1. The joint-fitting part 11 has a limiting groove 12 (see...). Figure 10 The limiting groove 12 is used to cooperate with the second insurance component 55 of the insurance mechanism 5.

[0120] The handle 2 is rotatable and retractable, mounted on the main body 1, for the user to lift or push. For example... Figures 1-10 As shown, in this embodiment, the handle 2 includes a first rod 21 and two second rods 22. The first rod 21 is inserted into the two second rods 22 and can move along the length direction of the two second rods 22 to extend or retract, thereby realizing the extension and retraction of the handle 2. The two second rods 22 are rotatably connected to both sides of the body 1 in the width direction (also the left-right direction), so as to drive the first rod 21 to rotate relative to the body 1, thereby realizing the rotation of the handle 2.

[0121] Specifically, in this embodiment, the first rod 21 includes a crossbeam 211 and two longitudinal beams 212. The two longitudinal beams 212 are connected to opposite ends of the crossbeam 211 and extend from the crossbeam 211 toward the body 1, making the first rod 21 approximately U-shaped with its opening facing the body 1. The two longitudinal beams 212 correspond one-to-one with the two second rods 22 and are respectively inserted into the corresponding second rods 22 to realize the insertion of the first rod 21 into the two second rods 22.

[0122] The two second rods 22 have identical structures, each including a rod body 23 and a rotating joint 24. The rod body 23 is hollow, allowing the first rod 21 to be inserted, thus achieving a sliding connection between the first rod 21 and the second rod 22. The rotating joint 24 is located at the lower end of the rod body 23 and rotatably fits around the joint fitting part 11 of the main body 1, enabling a rotatable connection between the first rod 21 and the main body 1, allowing the handle 2 to rotate relative to the main body 1. The rotating joint 24 has a mounting cavity 25, which houses the rotation control mechanism 4 and the safety mechanism 5. The mounting cavity 25 contains a first shaft 26, a second shaft 27, and two protrusions 28. The first shaft 26 and the second shaft 27 are arranged from bottom to top, while the two protrusions 28 are located on both sides of the axial direction of the first shaft 26. The mounting cavity 25 is closed by an end cap 29 for a smooth and aesthetically pleasing appearance.

[0123] In this embodiment, the first rod 21 has two telescopic positions: an extended position and a retracted position. The extended position is located above the retracted position, away from the rotating joint 24, corresponding to the longest length of the handle 2; while the retracted position is located below the extended position, close to the rotating joint 24, corresponding to the shortest length of the handle 2. Correspondingly, the second rod 22 has two locking holes (not shown in the figure), corresponding to the extended and retracted positions respectively, for cooperating with the telescopic locking member 31 of the telescopic control mechanism 3 provided on the first rod 21 to lock the first rod 21 in both the extended and retracted positions.

[0124] Furthermore, combined Figure 5 and Figure 10It is understood that in this embodiment, the first rod 21 and the second rod 22 are respectively provided with a first hole 213 and a second hole 221. The first hole 213 and the second hole 221 are at least partially aligned when the first rod 21 is in the retracted position, so that the second safety member 55 of the safety mechanism 5 can be inserted to further extend and lock the first rod 21 in the retracted position to prevent the first rod 21 from accidentally extending.

[0125] The telescopic control mechanism 3 is used to control the extension and retraction of the handle 2. For example... Figure 3 and Figure 4 As shown, in this embodiment, the telescopic control mechanism 3 includes a telescopic locking member 31, a first reset member 32, and a release member 33.

[0126] The telescopic locking member 31 is used to telescopically lock the first rod 21. It is set one-to-one with the longitudinal beam 212 of the first rod 21 and is located in the corresponding longitudinal beam 212 at a relatively low position. By extending out from the longitudinal beam 212 and engaging into the two locking holes of the corresponding second rod 22, the first rod 21 is locked in the retracted position and the extended position.

[0127] The first reset member 32 is a spring 34, which abuts against the inner wall of the telescopic locking member 31 and the first rod 21 to apply an elastic force to the telescopic locking member 31, causing the telescopic locking member 31 to extend outward from the first rod 21 and engage in the two locking holes (not shown in the figure) on the second rod 22, so that the telescopic locking member 31 can automatically reset and perform telescopic locking.

[0128] The release member 33 is used to control whether to release the telescopic locking member 31 from locking the first rod 21. In this embodiment, the release member 33 includes an operating member (not shown), two pulling members (not shown), and two traction members (not shown). The operating member is configured as a button, located on the crossbeam 211 of the first rod 21, and has two first wedge-shaped portions to engage with the second wedge-shaped portions on the two pulling members through wedge surfaces, so that when the operating member is pressed, the two pulling members slide towards each other. The two pulling members are located on both sides of the operating member and are connected to the two telescopic locking members 31 through the two traction members, so that when sliding towards each other, the two traction members pull the two telescopic locking members 31, causing the two telescopic locking members 31 to overcome the elastic force of the first reset member 32 and disengage from the locking hole, thus releasing the telescopic locking members 31 from locking the first rod 21.

[0129] As can be seen, based on the telescopic control mechanism 3, the user can control whether the telescopic locking member 31 locks the first rod 21 by pressing the release member 33, and thus control whether the first rod 21 is locked in the extended position or the retracted position, or whether it telescopically extends between the extended position and the retracted position.

[0130] The rotation control mechanism 4 is used to control the rotation of the handle 2. For example... Figures 3-10As shown, in this embodiment, the rotation control mechanism 4 corresponds one-to-one with the second rod 22, and includes a rotation locking member 41, a second reset member 42, an unlocking member 43, a linkage member 47, and an actuator 48.

[0131] The rotation locking member 41 is used to rotate and lock the rotational joint 24 and the joint mating part 11, so that the handle 2 cannot rotate relative to the body 1. Figure 3 As can be seen, in this embodiment, the rotating locking member 41 is constructed as a multi-tooth structure, with multiple teeth on its outer edge. Correspondingly, the rotating joint 24 and the joint mating part 11 are also provided with mating teeth. When the teeth on the rotating locking member 41 are engaged with the teeth on the rotating joint 24 and the joint mating part 11, the rotating joint 24 and the joint mating part 11 can be locked together, so that the rotating joint 24 cannot rotate relative to the joint mating part 11, thereby realizing the rotational locking of the handle 2.

[0132] In this embodiment, the rotation locking member 41 is sleeved on the first shaft 26 of the rotation joint 24. The first shaft 26 is located at the rotation center of the rotation joint 24, such that the axial direction of the first shaft 26 is consistent with the rotation axis of the rotation joint 24. Furthermore, the rotation locking member 41 can move along the first shaft 26 to approach and move away from the rotation joint 24 along the rotation axis of the rotation joint 24. The position where the rotation locking member 41 is close to the rotation joint 24 and engages with both the rotation joint 24 and the joint mating part 11 is called the locked position, and the position where the rotation locking member 41 is away from the rotation joint 24 and disengaged from the rotation joint 24 is called the unlocked position.

[0133] As can be seen, in this embodiment, the rotating locking member 41 rotates to lock and unlocks the handle 2 in the locked and unlocked positions, respectively, and the rotating locking member 41 moves between the locked and unlocked positions by moving along the rotation axis of the rotating joint 24.

[0134] The second reset member 42 is a spring 34, which abuts against the rotation locking member 41 and the joint mating part 11 to apply an elastic force to the rotation locking member 41 to return the rotation locking member 41 to the locked position, so that the rotation locking member 41 can automatically reset and perform rotation locking.

[0135] The unlocking component 43 is driven to connect with the rotation locking component 41, and is used to drive the rotation locking component 41 to move between the locked position and the unlocked position, so as to control whether the rotation locking component 41 is rotated and locked. Figure 3 and Figure 4 As shown, in this embodiment, the unlocking member 43 is configured as a handle that extends into the mounting cavity 25 of the rotating joint 24 and is movable along the extension and retraction direction of the handle 2, so that the unlocking member 43 can be pulled along the extension direction of the first rod 21. Specifically, as Figure 4As shown, in this embodiment, the unlocking member 43 includes a horizontal portion 44 and a vertical portion 45. The vertical portion 45 extends approximately along the extension direction of the handle 2, while the horizontal portion 44 is configured as a pull lug, connected to the upper end of the vertical portion 45 and bent relative to the vertical portion 45, forming an approximately 90° angle with the vertical portion 45, making the unlocking member 43 approximately L-shaped. The vertical portion 45 extends into the mounting cavity 25 via an opening on the top wall of the mounting cavity 25 of the rotating joint 24, while the horizontal portion 44 is located outside the mounting cavity 25 and fitted onto the rod body 23 of the second rod 22, allowing the user to grasp the horizontal portion 44 and apply force along the extension direction of the handle 2 to pull the unlocking member 43 upwards.

[0136] The unlocking component 43 is operated by pulling along the extension direction of the first rod 21, which is more ergonomic and saves time and effort. Furthermore, since the unlocking component 43 is fitted onto the second rod 22, the second rod 22 can guide the unlocking component 43 during its movement, directing it to move more accurately along the extension direction of the first rod 21, thus further facilitating user operation.

[0137] The unlocking component 43 is sequentially connected to the rotating locking component 41 via the linkage component 47 and the actuator component 48. Together, the linkage component 47 and the actuator component 48 convert the movement of the unlocking component 43 along the extension direction of the first rod 21 into the movement of the rotating locking component 41 from the locked position to the unlocked position. This allows the rotating locking component 41 to move from the locked position to the unlocked position when the unlocking component 43 is pulled, thereby rotating and unlocking the handle 2 so that the user can rotate the handle 2.

[0138] Combination Figures 4-6As can be seen, in this embodiment, the actuator 48 is sleeved on the first shaft 26 and located on the side of the rotation locking member 41 away from the joint mating part 11, and is in contact with the rotation locking member 41, so that when the actuator 48 moves along the first shaft 26 in a direction away from the rotation joint 24, it can drive the rotation locking member 41 to move along the first shaft 26 in a direction away from the rotation joint 24, so that the rotation locking member 41 moves from the locked position to the unlocked position. Furthermore, in this embodiment, the actuator 48 is approximately cylindrical and rotatably mounted on the first shaft 26. A groove 49 is provided on the outer edge of the sidewalls on opposite sides of its center. Correspondingly, a protrusion 28 is provided on the bottom wall of the mounting cavity 25 on opposite sides of the first shaft 26. The two protrusions 28 and the two grooves 49 are matched one-to-one. Inclined surfaces 281 are provided on the protrusions 28 and the grooves 49, extending along the rotation direction of the actuator 48 and varying in height, so that the protrusions 28 and the grooves 49 respectively form a wedge-shaped block and a wedge-shaped groove. Thus, during the rotation of the actuator 48 around the first shaft 26, with the cooperation of the inclined surfaces 281 of the protrusions 28 and the grooves 49, it synchronously moves along the first shaft 26, moving away from the rotation joint 24. This drives the rotation locking member 41 to move away from the rotation joint 24, causing the rotation locking member 41 to no longer engage with the rotation joint 24, thereby releasing the rotation lock.

[0139] Linkage component 47 is used to realize the driving connection between unlocking component 43 and actuating component 48, so as to convert the movement of unlocking component 43 when it is pulled into the rotation of actuating component 48. Figure 7 As shown, in this embodiment, the linkage 47 is a pull rope 471 (such as a steel wire). The pull rope 471 connects the unlocking component 43 and the actuator 48, and the connection position with the actuator 48 is located on one side of the rotation center of the actuator 48. That is, the pull rope 471 is connected to one side of the rotation center of the actuator 48. For example, a wiring hole 40 can be provided on one side of the rotation center of the actuator 48 to realize the connection between the pull rope 471 and one side of the rotation center of the actuator 48. Thus, see Figure 8 and Figure 9 When the unlocking member 43 is pulled upward, the pull rope 471 can pull the actuator 48, causing the actuator 48 to rotate around the first axis 26. Thus, under the mutual contact action of the protrusion 28 and the inclined surface 281 of the groove 49, the actuator 48 rotates away from the rotating joint 24, pushing the rotating locking member 41 to the unlock position.

[0140] As can be seen, with the cooperation of the unlocking component 43, the linkage component 47, the actuating component 48 and the rotation locking component 41, the rotation control mechanism 4 can control whether the handle 2 rotates. In particular, when the unlocking component 43 is pulled, the rotation control mechanism 4 can release the rotation lock on the handle 2 by moving the rotation locking component 41 from the locked position to the unlocked position, so that the handle 2 can be rotated.

[0141] The safety mechanism 5, based on the telescopic control mechanism 3 and the rotation control mechanism 4, further locks the handle 2 for rotation and telescopic movement, thereby improving the safety of the basket 10. For example... Figure 4 and Figure 10 As shown, in this embodiment, the safety mechanism 5 corresponds one-to-one with the second rod 22, and is rotatably disposed in the mounting cavity 25 of the rotating joint 24 corresponding to the second rod 22, and includes a first safety element 51, a second safety element 55 and an elastic element 54.

[0142] The first locking element 51 is used to further lock the handle 2 by rotation, and the locking of the unlocking element 43 further locks the handle 2 by rotation. Figure 4 and Figure 10 As can be seen, in this embodiment, the first safety element 51 is rotatably sleeved on the second shaft 27 in the mounting cavity 25, and includes hooks 52 and rotating arms 53 located on both sides of the second shaft 27 (or the rotation center of the first safety element 51). The hooks 52 are located on the side of the rotation center of the first safety element 51 closer to the unlocking element 43, and are used to engage with the slots 46 on the unlocking element 43 to achieve engagement between the first safety element 51 and the unlocking element 43. The rotating arm 53 is located on the side away from the unlocking member 43 at the rotation center of the first safety member 51, and extends out from the mounting cavity 25 and enters the rod body 23 of the second rod 22. This allows the first rod 21 to push the rotating arm 53 and drive the first safety member 51 to rotate around the second axis 27 as the first rod 21 moves from the extended position to the retracted position. This allows the first safety member 51 to rotate from the first position where the hook 52 is engaged with the slot 46 to the second position where the hook 52 is disengaged from the slot 46, and rotates to the second position exactly when the first rod 21 moves to the retracted position.

[0143] When the first safety element 51 is in the first position, the hook 52 of the first safety element 51 engages with the slot 46 of the unlocking element 43, thus locking the unlocking element 43 and preventing it from being pulled. When the first safety element 51 rotates to the second position, the hook 52 of the first safety element 51 disengages from the slot 46 of the unlocking element 43, thus releasing the first safety element 51 from locking the unlocking element 43. The unlocking element 43 is no longer constrained by the first safety element 51 and can therefore be pulled by the user to release the rotation lock 41 from locking the handle 2.

[0144] Since the first safety element 51 is configured to rotate from the first position to the second position only when the first lever 21 moves to the retracted position, the unlocking element 43 can only be pulled when the first lever 21 moves to the retracted position, thus releasing the rotation lock 41 from the handle 2. This effectively prevents the user from accidentally operating the unlocking element 43 when the handle 2 is not at its shortest length, so as to avoid safety risks such as the basket tipping over due to the accidental rotation of the handle 2. Therefore, the rotation safety of the handle 2 can be effectively improved, thereby improving the safety of the basket 10 in use.

[0145] The second safety component 55 is used to further extend and lock the handle 2, and by locking the first rod 21 in the retracted position when the angle of the basket 10 is greater than a preset angle, further extension and locking of the handle 2 is achieved. Figure 4 and Figure 10 As shown, in this embodiment, the second safety element 55 is rotatably mounted on the second shaft 27 and located on the side of the first safety element 51 away from the rotation joint 24. Thus, the second safety element 55 and the first safety element 51 are rotatably coaxially arranged and sequentially arranged along a direction away from the rotation joint 24. Furthermore, in this embodiment, the second safety element 55 includes a first segment 56 and a second segment 57. The first segment 56 and the second segment 57 are located on the same side of the second shaft 27 (or the rotation center of the second safety element 55), and the second segment 57 is connected to the end of the first segment 56 away from the second shaft 27, and is bent relative to the first segment 56, forming an approximately 90° angle with the first segment 56, making the second safety element 55 approximately L-shaped. The thickness of the second segment 57 is less than the thickness of the first segment 56 so that the second segment 57 can be inserted into the first rod 21.

[0146] The second safety element 55 moves between a third position and a fourth position by rotation. In the third position, the second segment 57 of the second safety element 55 extends from the mounting cavity 25 through the second hole 221 on the second rod 22, enters the rod body 23, and engages with the first hole 213 of the first rod 21 in the retracted position, locking the first rod 21 in the retracted position and preventing it from extending. In the fourth position, the second segment 57 of the second safety element 55 disengages from the first hole 213 and the second hole 221, and together with the first segment 56, embeds into the limiting groove 12 on the body 1, thereby releasing the lock on the first rod 21 in the retracted position.

[0147] The elastic element 54 is a torsion spring, which is sleeved on the second shaft 27 and located between the first safety element 51 and the second safety element 55. It applies a reverse torque to the first safety element 51 and the second safety element 55, causing the first safety element 51 to have a tendency to rotate from the second position to the first position, and the second safety element 55 to have a tendency to rotate from the third position to the fourth position. Under the action of the elastic element 54, the first safety element 51 and the second safety element 55 are normally held in the first position and the fourth position, respectively, and can automatically return to the first position and the fourth position when needed.

[0148] In this embodiment, the rotation of the second safety component 55 from the fourth position to the third position is driven by the handle 2 during the rotation of the handle 2 from a preset angle to a direction greater than the preset angle. This means that the second safety component 55 does not perform telescopic locking when the handle 2 is at the preset angle, but only performs telescopic locking when the angle of the handle 2 is greater than the preset angle.

[0149] Here, the angle of the handle 2 refers to the angle between the extension direction of the handle 2 and the plane containing the bottom surface of the body 1. For example, see... Figure 2 When pushing forward (or in a forward direction), the angle of handle 2 is the angle between the extension direction of handle 2 and the forward direction of the main body 1; when pushing backward, the angle of handle 2 is the angle between the extension direction of handle 2 and the backward direction of the main body 1. The preset angle is the angle of handle 2 in the pushing mode. The specific value of the preset angle can be determined by referring to the pushing height that is more comfortable or less strenuous for the user when pushing the stroller, such as 45° or 60°. When handle 2 rotates from the preset angle to a direction greater than the preset angle, it usually means that the user wants to switch from the pushing mode to the carrying mode, and when the angle of handle 2 is greater than the preset angle, it usually corresponds to the carrying mode. In the corresponding carrying mode, the user can rotate handle 2 to a suitable angle position as needed.

[0150] Therefore, by configuring the second safety element 55 to move from the fourth position to the third position only during the rotation of the handle from the preset angle position in the direction of increasing angle, the second safety element 55 can lock the first rod 21 in the retracted position only when the basket 10 switches from the push mode to the lift mode, and when it is in the lift mode, to prevent the handle 2 from suddenly extending under the corresponding working conditions, causing problems such as fright and injury to children. When the angle of the handle 2 is the preset angle, that is, in the push mode, the second safety element 55 does not lock the first rod 21 in the extension position. In this way, the handle 2 can extend and retract in the normal push mode to meet the push needs of different heights.

[0151] Figure 10 The illustration shows the state changes of the handle 2 during the switching process from push mode to lift mode of the basket 10 in this embodiment.

[0152] like Figure 10 As shown, when the handle 2 is in the normal pushing mode, the handle 2 is in a preset angle position, and the first rod 21 is in the extended position. Correspondingly, the first safety element 51 is in the first position, and the hook 52 is engaged in the slot 46 of the unlocking element 43, preventing the unlocking element 43 from being pulled (see...). Figure 10 (The first image from the left in the middle) to prevent the handle 2 from being accidentally rotated due to the unlocking component 43 being pulled, which could cause the basket to tip over. At the same time, the second safety component 55 is in the fourth position, and the first segment 56 and the second segment 57 are embedded in the limiting groove 12 of the main body 1 (see...). Figure 10 (Second image from the left in the middle); When the user wants to switch to the lifting mode, the user pushes the first lever 21 downwards, causing the first lever 21 to move downwards to the retracted position. During this process, the first lever 21 pushes the rotating arm 53 of the first safety component 51, causing the first safety component 51 to rotate to the second position, disengaging the hook 52 from the slot 46, releasing the first safety component 51 from the unlocking component 43, making the unlocking component 43 able to be pulled (see...). Figure 10 (The third image from the left in the middle); then, pull the unlocking piece 43, causing the unlocking piece 43 to drive the rotation locking piece 41 to disengage from the rotation joint 24 via the linkage piece 47 and the actuator 48, releasing the rotation locking effect of the rotation locking piece 41, allowing the handle 2 to be rotated. With the handle 2 rotatable, rotate the handle 2 in a direction greater than a preset angle, causing the handle 2 to drive the second safety piece 55 to disengage from the limiting groove 12 and rotate towards the third position (see...). Figure 10 (The fourth image from the left in the middle) After the second safety component 55 rotates to the third position, the second segment 57 of the second safety component 55 engages with the first lever 21, locking the first lever 21 in the retracted position (see...). Figure 10 (The fifth image from the left in the middle) ensures that the handle 2 cannot extend when the angle is greater than the preset angle, in order to prevent the handle 2 from suddenly extending.

[0153] As can be seen, in this embodiment, the rotation of the handle 2 is controlled by both the rotation control mechanism 4 and the first safety element 51. The first safety element 51 can improve the rotation safety of the handle 2 by controlling the unlocking part 43 of the rotation control mechanism 4 to be pulled only when the handle 2 is at its shortest position. Moreover, the extension and retraction of the handle 2 is controlled by both the extension and retraction control mechanism 3 and the second safety element 55. The second safety element 55 can improve the extension and retraction safety of the handle 2 by locking the handle 2 at its shortest position when the angle of the handle 2 is greater than a preset angle. In this way, the handle 2 is less likely to rotate or extend accidentally, thus effectively improving the safety of the basket 10.

[0154] Furthermore, in this embodiment, the unlocking element 43 is constructed as a handle, which makes it more convenient for users to operate, saves time and effort, and helps to improve the user experience of the basket 10.

[0155] The above description is merely an exemplary embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
