Description

Technical Field

[0001] This application relates to the field of children's products technology, and in particular to a folding rocking chair. Background Technology

[0002] In the modern childcare product market, children's rocking chairs are a common and practical item, providing infants and toddlers with a comfortable space for rest and activity. Foldable children's rocking chairs, in particular, are favored by many parents due to their ease of storage and portability.

[0003] While current foldable children's rocking chairs are equipped with locking mechanisms, these mechanisms are prone to accidental unlocking during actual use. This is mainly due to two reasons: either the locking mechanism is poorly designed and cannot withstand the vibrations and external forces generated by a child's movements on the rocking chair, or the mechanism is too simple to operate, making it easy for a child to accidentally unlock it while playing. Once the locking mechanism is accidentally unlocked, the rocking chair may suddenly fold, causing serious injury to the child. For example, the locking button on some rocking chairs is poorly positioned, allowing a child to easily reach it and accidentally release the lock. With increasingly stringent safety requirements for children's products, developing a folding rocking chair with higher safety and stability in its folding and unfolding structure is of significant practical importance and market demand.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide a folding rocking chair to improve the safety and reliability of the folding rocking chair.

[0006] To achieve the above objectives, this application employs the following technical solution:

[0007] This application provides a folding rocking chair, including a shift seat, a shift block, a locking block, an unlocking handle, a safety mechanism, and a rocker arm for supporting the support frame;

[0008] The gear position seat is provided with a locking groove, which is used to cooperate with the locking block to realize the folding and locking of the rocker arm;

[0009] The unlocking handle is connected to the gear shift block and is used to drive the gear shift block to be housed in the receiving cavity of the gear shift seat in order to adjust the gear position of the rocker arm.

[0010] The unlocking handle is also connected to the locking block for driving the locking block to avoid the rocker arm, so that the rocker arm enters or disengages from the locking groove;

[0011] The safety mechanism is used to restrict the movement of the unlocking handle, and can release the restriction on the movement of the unlocking handle under external force.

[0012] Optionally, the unlocking handle is connected to the gear shift block via a linkage mechanism.

[0013] Optionally, the linkage mechanism includes a first link, a second link, and a third link connected in sequence, wherein the first link is induced to the unlocking handle, and the third link is induced to the gear shift block;

[0014] A positioning shaft is provided between the two connection points of the second link and the first link and the third link; the positioning shaft is relatively fixed to the gear seat and is rotatably connected to the second link.

[0015] Optionally, the end of the third link connected to the gear block is provided with a sliding groove, and the gear block is provided with a sliding pin; the sliding pin is inserted into the sliding groove and slidably connected with the sliding groove.

[0016] Optionally, the gear block includes a gear body and gear teeth connected to the gear body; the gear seat has a gear hole communicating with the receiving cavity; the gear body is supported in the receiving cavity by a first elastic member; the first elastic member is used to drive the gear block received in the receiving cavity to reset after the force of the unlocking handle is removed, so that the gear teeth extend out from the gear hole.

[0017] Optionally, the safety mechanism includes a resettable safety button, the safety button having a first limiting part, and the unlocking handle having a second limiting part. When the safety button is in a non-forced state, the first limiting part abuts against the second limiting part to restrict the movement of the unlocking handle; when the safety button is driven by an external force, the first limiting part avoids the second limiting part to release the restriction on the movement of the unlocking handle.

[0018] Optionally, the safety button includes a button body and a second elastic element that drives the button body to reset.

[0019] Optionally, the locking block is configured with a third elastic element that drives the locking block to reset.

[0020] Optionally, the folding rocking chair further includes a housing and a rotating base. The housing is connected to the rotating base to form a cavity that can accommodate the gear shift seat, gear shift block, and locking block. The unlocking handle and the safety mechanism are at least partially exposed outside the housing.

[0021] The rotating seat is rotatably mounted on the bottom base via a rotation drive mechanism, and the bottom base is also connected to a rear support with an adjustable length.

[0037] 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.

[0038] like Figure 1 , Figure 2 As shown, the folding rocking chair provided in this embodiment includes a gear seat 1, a gear block 2, a locking block 3, an unlocking handle 4, a safety mechanism, and a rocker arm 6 for supporting the load.

[0039] The gear shift block 2 is used to limit the rocker arm 6 to adjust its tilt angle. More specifically, the gear shift block 2 is kinetically connected to the unlocking handle 4. When shifting gears, pulling the unlocking handle 4 drives the gear shift block 2, causing it to be housed within the receiving cavity 102 of the gear shift seat 1, thereby releasing the limitation on the rocker arm 6. At this time, lifting or pressing the rocker arm 6 upwards or downwards to the desired gear position and releasing the unlocking handle 4 to reset the gear shift block 2 will re-limit the rocker arm 6, completing the gear shift.

[0040] The gear shift seat 1 is provided with a locking groove 101. In the folded state, the locking block 3 can form a locking interval with the locking groove 101. This locking interval can limit the rocker arm 6, thereby realizing the folding and locking of the rocker arm 6. The unlocking handle 4 is also connected to the locking block 3. Pulling the unlocking handle 4 can drive the locking block 3 to avoid the rocker arm 6, so that the aforementioned locking interval is in an open state, thereby allowing the rocker arm 6 to enter or disengage from the locking groove.

[0041] See Figure 3 The locking block 3 is equipped with a third elastic element 301 that drives it to reset. When an external force drives the locking block 3 to avoid the rocker arm 6, the third elastic element 301 can automatically reset it, ensuring the continuous effectiveness of the locking function.

[0042] The safety mechanism is used to restrict the movement of the unlocking handle 4, and can release the restriction on the movement of the unlocking handle 4 under external force. That is to say, the unlocking handle 4 can only be pulled when the safety mechanism is driven by external force, so as to realize the shifting, folding and unfolding operations of the folding rocking chair.

[0043] The folding locking and unlocking process of the folding rocking chair provided in this embodiment is described in detail below: When folding the rocker arm 6, first operate the safety button 501 to release the restriction on the unlocking handle 4, then pull the unlocking handle 4. The unlocking handle 4 simultaneously drives the locking block 3 to avoid the rocker arm 6, and the third elastic element 301 is compressed, allowing the rocker arm 6 to enter or disengage from the locking groove 101. When the rocker arm 6 is folded into place, the locking block 3 resets under the reaction force of the compressed third elastic element 301, and engages with the locking groove 101 to lock the rocker arm 6 in the folded state. To unlock the folding, repeat the above operation, drive the locking block 3 to avoid the rocker arm 6, and disengage the rocker arm 6 from the locking groove 101.

[0044] In summary, the folding rocking chair provided in this embodiment, with its safety mechanism and unlocking handle 4 working together to form two safety locks, can prevent accidental unlocking during use, greatly improving the safety and reliability of the folding rocking chair.

[0045] In some embodiments, the gear shift block 2 includes a gear shift body 202 and one or more gear shift teeth 203 connected to the gear shift body 202. The gear shift seat 1 has a gear shift hole 103 communicating with the receiving cavity 102. One gear shift tooth 203 corresponds to one gear shift hole 103 and one gear. The lower end face of the gear shift tooth 203 is provided with a guide surface. When the rocker arm 6 is lifted upward, the rocker arm 6 will squeeze the gear shift tooth 203 and slide it upward along the guide surface, so that the gear shift tooth 203 is passively retracted into the receiving cavity 102, thereby realizing gear shifting. The gear shift body 202 is supported in the receiving cavity 102 by a first elastic member 204. The first elastic member 204 is used to drive the gear shift block 2 received in the receiving cavity 102 to reset after the force of the unlocking handle 4 is removed, so that the gear shift tooth 203 retracted into the receiving cavity 102 can extend out of the gear shift hole 103 again, realizing stable engagement of different gears.

[0046] As one embodiment of this application, the unlocking handle 4 can be connected to the gear block 2 via a linkage mechanism, as detailed below:

[0047] The linkage mechanism may include a first link 401, a second link 402, and a third link 403 connected in sequence. The second link 402 is rotatable relative to both the first link 401 and the third link 403 around its connection point. The first link 401 is drive-connected to the unlocking handle 4, and the third link 403 is drive-connected to the gear shift block 2. A positioning shaft 404 is provided between the two connection points of the second link 402 and the first link 401 and the third link 403. The positioning shaft 404 is relatively fixed to the gear shift seat 1 (it can be fixed to the rotating seat 8 or the housing 7 by welding, bolting, etc.) and rotatably connected to the second link 402, forming a lever-like transmission structure to ensure stable driving of the gear shift block 2 when the unlocking handle 4 is activated.

[0048] like Figure 3 As shown, the end of the third link 403 connected to the gear block 2 has a groove 4031. The gear block 2 has a sliding pin 201, which is inserted into the groove 4031 and slidably connected to it. This sliding engagement method can adapt to the linear motion requirements of the gear block 2 during the transmission of the linkage mechanism, avoiding transmission interference. The third link 403 is generally a long strip-shaped rod structure. The shape of the groove 4031 is adapted to the sliding requirements of the sliding pin 201 on the gear block 2. It is usually a rectangular groove with smooth edges to reduce friction when the sliding pin 201 slides.

[0049] It should be noted that the unlocking handle 4 is not limited to being connected to the gear block 2 via a linkage mechanism. In some embodiments, the unlocking handle 4 can also be connected to the gear block 2 via other transmission mechanisms. For example, a traction rope can be used to connect the unlocking handle 4 and the gear block 2, and a pulley system can be used to achieve traction reversal, thereby realizing the transmission between the unlocking handle 4 and the gear block 2. Alternatively, a transmission mechanism consisting of a gear and a rack can be used to connect the rack to the unlocking handle 4, with the rack driving the gear, and the gear rotation driving the gear block 2. For those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.

[0050] As one embodiment of this application, the safety mechanism includes a resettable safety button 501. The safety button 501 has a first limiting portion 5011, and correspondingly, the unlocking handle 4 has a second limiting portion 405. When the safety button 501 is in a non-forced state, the first limiting portion 5011 abuts against the second limiting portion 405 to restrict the unlocking handle 4 from being pulled. The safety button 501 includes a button body 5012 and a second elastic member 502 that drives the button body 5012 to reset. When the button body 5012 is pressed, the button body 5012 compresses the second elastic member 502, separating the first limiting portion 5011 from the second limiting portion 405 and providing clearance for the second limiting portion 405, thereby releasing the restriction on the movement of the unlocking handle 4. After the safety button 501 is released, the second elastic member 502 drives the button body 5012 to reset, and the first limiting portion 5011 abuts against the second limiting portion 405 again, restoring the restriction on the unlocking handle 4.

[0051] In some embodiments, the folding rocking chair further includes a housing 7 and a rotating base 8. The housing 7 is connected to the rotating base 8, forming a cavity that can accommodate the gear shift seat 1, the gear shift block 2, and the locking block 3. The unlocking handle 4 and the safety mechanism are at least partially exposed outside the housing 7 for easy user operation.

[0052] The rotating base 8 is rotatably mounted on the bottom base 10 via a rotation drive mechanism 9. A rear support 11 is also connected to the bottom base 10. The length of the rear support 11 is adjustable; specifically, it can employ a telescopic rod, threaded adjustment, or other structures, not shown in the figure. The adjustable length of the rear support 11 can adapt to different usage scenarios and ground heights. Adjustment can be achieved by stretching or retracting the rear support 11 as needed and then locking it.

[0053] An operation panel 13 is provided on the bottom base 10. Commands can be sent through the operation panel 13 to control the rotation drive mechanism 9 to drive the rotating seat 8 and the rocking chair body to rotate. The rotation drive mechanism 9 is equipped with a rotation sensor, which can sense the rotation direction and rotation angle of the rotating seat 8 in real time and provide feedback to ensure precise rotation adjustment.
