Abstract
Description
Technical Field
[0001] This utility model relates to the field of child seat technology, specifically to a base flip-up device and a child seat. Background Technology
[0002] Child car seats are crucial for ensuring children's safety while traveling, and their structural design must balance ergonomics and functionality. Currently, most child car seats on the market use fixed base structures or simple adjustable designs, which are showing limitations in practical use. While some existing products allow for changes in seat height and backrest angle through disassembly and reassembly or mechanical adjustment, these methods generally suffer from cumbersome adjustment procedures and insufficient locking stability. For example, pin-type positioning structures pose a risk of accidental dislodgement, while multi-position snap-on designs struggle to achieve continuous fine-tuning, making it difficult to accurately adapt to the constantly changing body shape of children as they grow. Furthermore, traditional adjustment mechanisms are often exposed on the outside of the seat, making them prone to accidental activation and malfunction, and exposed parts pose a risk of injury to children. Utility Model Content
[0003] Therefore, this utility model provides a base flip-up device and a child seat, making the adjustment of the child seat simpler and more convenient.
[0004] To solve the above problems, this utility model provides a base flipping device, which includes: a base body with a mating mounting position; a flipping assembly that is mated and connected to the mating mounting position; and a limiting component that is located on the base body and presses down on a portion of the flipping assembly. The flipping assembly moves under the restriction of the limiting component, causing a portion of the flipping assembly to protrude from the base body.
[0005] Compared to existing technologies, this technical solution achieves the following technical benefits: Through the coordinated design of the seat, flip-up assembly, and limiting assembly, it integrates height adjustment and backrest angle adjustment. Specifically, the flip-up assembly moves controllably under the dynamic constraint of the limiting assembly, with some of its structure protruding from the seat to form a support surface, thereby directly changing the vertical height or tilt angle of the seat base. Compared to traditional adjustment methods that require disassembly and reassembly or rely on multi-position latches, this design achieves stepless adjustment through the continuous pressing action of the limiting assembly, precisely adapting to the body differences of children of different ages. Furthermore, the internal linkage design of the limiting assembly and flip-up assembly effectively avoids exposed adjustment mechanisms, reducing the risk of accidental activation, while optimizing the internal force transmission path ensures locking stability after adjustment.
[0006] In one embodiment of this utility model, the base flipping device further includes: the flipping assembly is provided with a sliding shaft; a sliding space is provided between the limiting assembly and the base; and the sliding shaft slides in the sliding space.
[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: Through the precise cooperation between the sliding shaft and the sliding space, linear guiding motion of the flap assembly is realized. The constrained movement of the sliding shaft within the sliding space precisely controls the movement trajectory of the flap assembly, avoiding the radial offset problem easily caused by traditional hinge structures. Simultaneously, the sliding space provides physical displacement boundaries for the flap assembly, ensuring that the adjustment stroke is always within the design threshold, preventing mechanical interference caused by overextension.
[0008] In one embodiment of this utility model, the base flip-plate device further includes: a sliding space having a first end and a second end; defining the sliding shaft and the first end as a contact state for use, and the sliding shaft and the second end as a contact state for storage.
[0009] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting different states at both ends of the sliding space, the corresponding position and the corresponding state of the control base flip device are clearer, making it more convenient and faster to use.
[0010] In one embodiment of this utility model, the base flip-plate device further includes: the base is provided with a first limiting part and a second limiting part; when in use, the sliding shaft is engaged with the first limiting part, and the flip-plate assembly and the second limiting part abut against each other.
[0011] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting a first limiting part on the base to cooperate with the sliding shaft, the sliding shaft is fixed in the first limiting part, thereby preventing the flip-up assembly from moving back and forth during use, thus making it more stable during use. At the same time, the abutting cooperation between the second limiting part and the flip-up assembly makes the flip-up assembly more stable during use, preventing the flip-up assembly from moving back and forth, which would cause the angle and height adjustment of the child seat to fail and affect the child.
[0012] In one embodiment of this utility model, the base flip-plate device further includes: the flip-plate assembly is provided with a first mating part, the first mating part being recessed; the first mating part is used to cooperate with the second limiting part, so that the second limiting part is embedded in the first mating part, thereby cooperating with the first limiting part to fix the flip-plate assembly in the use state.
[0013] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting a recessed first mating part, the second limiting part is embedded in the first mating part for fixing, making the fixing and limiting simpler. The simple recessed structure simplifies the fixing structure, thereby reducing the occurrence of mechanical failures and making the overall structure more reliable. The embedded fit between the recessed first mating part and the second limiting part achieves a mechanical interlocking effect.
[0014] In one embodiment of this utility model, the base flip-plate device further includes: the flip-plate assembly is provided with a plurality of second mating parts; the base is provided with a plurality of third limiting parts; in use, the plurality of second mating parts and the plurality of third limiting parts abut against each other.
[0015] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: by setting multiple second mating parts to abut against multiple third limiting parts set on the base, the flip plate assembly can be better fixed on the base, and at the same time, it can better prevent the flip plate assembly from rotating in use, thus making it more stable during use.
[0016] In one embodiment of this utility model, the base flip-plate device further includes: the base is provided with a first placement groove; in the storage state, the flip-plate assembly is accommodated in the first placement groove.
[0017] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting the flip panel component to be stored in the first placement slot in the storage state, the flip panel component will not affect the normal use of the outside, nor will it protrude from the seat to affect children, thus preventing children from accidentally touching it and improving the overall safety performance.
[0018] In one embodiment of this utility model, the base flip-plate device further includes: the flip-plate assembly is provided with a limiting inclined surface; in the storage state, the limiting inclined surface and the second limiting part abut against each other.
[0019] Compared to existing technologies, the technical advantages of this solution are as follows: the wedge-shaped fit between the limiting inclined surface and the second limiting part creatively transforms the contact force in the retracted state into a self-locking force. When the flap assembly is fully retracted, the limiting inclined surface and the second limiting part form an angle, increasing the normal component of the external impact load and thus enhancing the contact surface normal pressure, thereby strengthening the locking effect. Furthermore, the preload generated by the inclined surface fit automatically compensates for wear gaps, ensuring the reliability of the device throughout its entire lifespan.
[0020] In one embodiment of this utility model, the base flip-plate device further includes: the base is provided with a plurality of fourth limiting parts; in the storage state, a plurality of second mating parts and a plurality of fourth limiting parts abut against each other.
[0021] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: by setting multiple fourth limiting parts to cooperate with multiple second cooperating parts to limit the flip panel assembly in the storage state, the flip panel assembly will not rotate in the storage state, thus making the fixation of the flip panel assembly more stable and preventing it from falling off the base on its own, thereby causing changes in the overall device and improving the overall stability of the device.
[0022] This utility model also provides a child seat, which further includes: a base flip-up device as described in any of the above claims; a backrest, which is rotatably connected to the base flip-up device.
[0023] Since the base flipping device contains any of the above-mentioned features, it has the same technical effect, which will not be elaborated here.
[0024] By adopting the technical solution of this utility model, the following technical effects can be achieved:
[0025] (1) Through the coordinated design of the seat, flip-up assembly, and limiting assembly, the integrated functions of height adjustment and backrest angle adjustment are realized. Specifically, the flip-up assembly moves controllably under the dynamic constraint of the limiting assembly, and part of its structure can protrude from the seat to form a support surface, thereby directly changing the vertical height or tilt angle of the seat base. Compared with the traditional adjustment method that requires disassembly and reassembly or relies on multi-position buckles, this design achieves stepless adjustment capability through the continuous pressing action of the limiting assembly, which can accurately adapt to the body differences of children of different ages. In addition, the internal linkage design of the limiting assembly and the flip-up assembly effectively avoids the exposure of the adjustment mechanism, reduces the risk of accidental touch, and at the same time, through the optimization of the internal mechanical transmission path, ensures the locking stability after adjustment;
[0026] (2) By setting a first limiting part on the base to cooperate with the sliding shaft, the sliding shaft is fixed in the first limiting part, thereby preventing the flip panel assembly from moving back and forth when in use, thus making it more stable when in use. At the same time, the second limiting part and the flip panel assembly abut against each other, making the flip panel assembly more stable when in use, preventing the flip panel assembly from moving back and forth, thus causing the angle and height adjustment of the child seat to fail, which would affect the child.
[0027] (3) By setting multiple second mating parts to engage with multiple third limiting parts on the base, the flip panel assembly can be better fixed on the base, and the flip panel assembly can be better prevented from rotating in the use state, thus making it more stable in use; by setting multiple fourth limiting parts to cooperate with multiple second mating parts to limit the flip panel assembly in the storage state, the flip panel assembly will not rotate in the storage state, thus making the flip panel assembly more stable and preventing it from falling off the base by itself, thereby causing changes in the overall device and improving the overall stability of the device.

[0038] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0039] [First Embodiment]
[0040] See Figures 1-6This utility model provides a base flipping device 100, which includes: a base 110, the base 110 having a mating mounting position; a flipping assembly 120, the flipping assembly 120 being mated and connected to the mating mounting position; and a limiting assembly 130, the limiting assembly 130 being disposed on the base 110 and pressing down on a portion of the flipping assembly 120; wherein, the flipping assembly 120 moves under the restriction of the limiting assembly 130, causing a portion of the flipping assembly 120 to protrude from the base 110.
[0041] Specifically, in actual use, when it is necessary to adjust the angle of the child seat 200, locate the flip panel assembly 120 under the child seat 200. In order to make it easier to pry out the flip panel assembly 120, a hand groove can be set on the flip panel assembly 120 so that fingers can grip and exert force to pull out the flip panel assembly 120.
[0042] Specifically, the flap assembly 120 is secured by the handle groove and pulled until it cannot be pulled any further. At this point, the sliding shaft 121 is fixed in the groove of the first limiting part 111, and the first mating part 122 and the second limiting part 112 provided on the base 110 are correspondingly engaged. The second limiting part 112 can be a stop block integrally formed with the base 110, and the protrusion of the stop block engages with the recess of the first mating part 122. In addition, multiple second mating parts 123 and multiple third limiting parts 113 are in abutting state at this time. The multiple second mating parts 123 can be protrusions, and the third limiting part 113 can be a groove on the base 110, so that the second mating parts 123 are inserted into the groove for limiting, thereby fixing the entire flap assembly 120. At this point, the angle adjustment is completed.
[0043] Furthermore, when not in use, simply push the flap assembly 120 in the opposite direction of where it was just pulled out until it can no longer be pushed. Here, the flap assembly 120 is completely accommodated in the first placement slot 114, and the second mating part 123 and multiple fourth limiting parts 115 abut against each other, so that the entire flap assembly 120 will not rotate, thus completing the storage.
[0044] Preferably, the integrated design of the seat 110, the flip-up assembly 120, and the limiting assembly 130 achieves both height adjustment and backrest angle adjustment. Specifically, the flip-up assembly 120 moves controllably under the dynamic constraint of the limiting assembly 130, and part of its structure protrudes from the seat 110 to form a support surface, thereby directly changing the vertical height or tilt angle of the seat base. Compared to traditional adjustment methods that require disassembly and reassembly or rely on multi-position latches, this design achieves stepless adjustment capability through the continuous pressing action of the limiting assembly 130, which can accurately adapt to the body differences of children of different ages. In addition, the internal linkage design of the limiting assembly 130 and the flip-up assembly 120 effectively avoids exposed adjustment mechanisms, reduces the risk of accidental activation, and ensures locking stability after adjustment through the optimization of the internal force transmission path.
[0045] Specifically, the base flip device 100 also includes: the flip assembly 120 is provided with a sliding shaft 121; the limiting assembly 130 and the base are provided with a sliding space 140; the sliding shaft 121 slides in the sliding space 140.
[0046] Preferably, the linear guiding motion of the flap assembly 120 is achieved through the precise cooperation between the sliding shaft 121 and the sliding space 140. The constrained movement of the sliding shaft 121 within the sliding space 140 can precisely control the movement trajectory of the flap assembly 120, avoiding the radial offset problem that is prone to occur in traditional hinge structures. At the same time, the sliding space 140 provides a physical displacement boundary for the flap assembly 120, ensuring that the adjustment stroke is always within the design threshold, preventing mechanical interference caused by overextension.
[0047] Specifically, the base flip device 100 also includes: a sliding space 140 having a first end 150 and a second end 160; the sliding shaft 121 and the first end 150 are defined as being in use when they are in contact, and the sliding shaft 121 and the second end 160 are in storage when they are in contact.
[0048] Preferably, by setting different states at both ends of the sliding space 140, the corresponding position and the corresponding state when operating the control base flip device 100 are clearer, making it more convenient and faster to use.
[0049] Specifically, the base flip device 100 also includes: the base is provided with a first limiting part 111 and a second limiting part 112; when in use, the sliding shaft 121 is engaged with the first limiting part 111, and the flip assembly and the second limiting part 112 abut against each other.
[0050] Preferably, by setting a first limiting part 111 on the base to cooperate with the sliding shaft 121, the sliding shaft 121 is fixed in the first limiting part 111, thereby preventing the flip-up assembly 120 from moving back and forth during use, thus making it more stable during use. At the same time, the second limiting part 112 and the flip-up assembly 120 abut against each other, making the flip-up assembly 120 more stable during use, preventing the flip-up assembly 120 from moving back and forth, which would cause the angle and height adjustment of the child seat 200 to fail and affect the child.
[0051] Specifically, the base flip device 100 further includes: the flip assembly 120 is provided with a first mating part 122, the first mating part 122 is recessed; the first mating part 122 is used to cooperate with the second limiting part 112, so that the second limiting part 112 is embedded in the first mating part 122, thereby cooperating with the first limiting part 111 to fix the flip assembly 120 in the use state.
[0052] Preferably, by providing a recessed first mating part 122, the second limiting part 112 is embedded in the first mating part 122 for engagement and fixation, making the fixation and limiting simpler. The simple recessed structure simplifies the fixing structure, reduces the occurrence of mechanical failures, and makes the overall structure more reliable. The embedded engagement of the recessed first mating part 122 and the second limiting part 112 achieves a mechanical interlocking effect.
[0053] Specifically, the base flip device 100 also includes: the flip assembly 120 is provided with a plurality of second mating parts 123; the base is provided with a plurality of third limiting parts 113; in use, the plurality of second mating parts 123 and the plurality of third limiting parts 113 abut against each other.
[0054] Preferably, by providing multiple second mating parts 123 to engage with multiple third limiting parts 113 provided on the base, the flip plate assembly 120 can be better fixed on the base, and the flip plate assembly 120 can be better prevented from rotating during use, thus making it more stable during use.
[0055] Specifically, the base flip device 100 also includes: the base is provided with a first placement groove 114; in the storage state, the flip assembly 120 is accommodated in the first placement groove 114.
[0056] Preferably, by setting the flip panel assembly 120 to the storage state and storing it in the first placement slot 114, the flip panel assembly 120 will not affect the normal use of the outside, nor will it protrude from the seat 110 to affect children, thus preventing children from accidentally touching it and improving the overall safety performance.
[0057] Specifically, the base flip device 100 also includes: the flip assembly 120 is provided with a limiting slope 124; in the storage state, the limiting slope 124 and the second limiting part 112 abut against each other.
[0058] Preferably, the wedge-shaped fit design of the limiting inclined surface 124 and the second limiting part 112 creatively transforms the contact force in the retracted state into a self-locking force. When the flap assembly 120 is fully retracted, the limiting inclined surface 124 and the second limiting part 112 form an angle, increasing the normal component of the external impact load and the normal pressure on the contact surface, thereby enhancing the locking effect. In addition, the preload generated by the inclined surface fit can automatically compensate for wear gaps, ensuring the reliability of the device throughout its entire life cycle.
[0059] Specifically, the base flip device 100 also includes: the base is provided with a plurality of fourth limiting parts 115; in the storage state, a plurality of second mating parts 123 and a plurality of fourth limiting parts 115 abut against each other.
[0060] Preferably, by setting multiple fourth limiting parts 115 to cooperate with multiple second cooperating parts 123 to limit the flip panel assembly 120 in the storage state, the flip panel assembly 120 will not rotate in the storage state, thereby making the fixation of the flip panel assembly 120 more stable and preventing it from falling off the base on its own, thus causing changes to the overall device and improving the overall stability of the device.
[0061] See Figure 7 The present invention also provides a child seat 200, which further includes: a base flip-up device 100 as described above; and a backrest 210, which is rotatably connected to the base flip-up device 100.
[0062] Since the base flip-plate device 100 contains any of the above-mentioned features, it has the same technical effect, which will not be described in detail here.
[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
