Description

Technical Field

[0001] This utility model relates to the field of nursing chair technology, and in particular to a nursing chair. Background Technology

[0002] Nursing chairs are chairs specifically designed for breastfeeding women. A comfortable nursing chair can provide good support and a relaxing environment for the feeder while she is feeding her baby.

[0003] Currently, most nursing chairs on the market achieve angle adjustments through local components such as the backrest or leg rest, thereby improving the user's feeding posture. However, because nursing chairs are generally bulky, adjusting their backrests or leg rests requires a lot of time and effort, and the entire process is slow, inflexible, inefficient, and uncomfortable for the user. Utility Model Content

[0004] The main purpose of this utility model is to propose a nursing chair that aims to solve the problems of poor flexibility in adjusting the posture of the chair body and poor user experience of traditional nursing chairs.

[0005] To achieve the above objectives, this utility model proposes a nursing chair, including a chair frame and a seat body disposed on the chair frame. The chair frame includes a first limiting part, a swinging part, and a second limiting part arranged sequentially along its swinging direction. The swinging part has a swinging arc surface in contact with the ground, and the chair frame can be driven to swing by adjusting the contact position between the swinging arc surface and the ground. The curvature of the first limiting part and the second limiting part is greater than the curvature of the swinging part, and both are located on the side of the swinging part closer to the seat body, and can restrict the continued movement of the chair frame in the swinging direction.

[0006] In one possible implementation, the projection of the center of gravity of the nursing chair falls within the swaying arc surface in the direction perpendicular to the line containing the swaying direction.

[0007] In one possible implementation, the distance between the center of gravity of the nursing chair and the lowest point of the rocking arc surface is 11cm to 31cm.

[0008] In one possible implementation, the chord length of the rocking portion is greater than the chord length of the first limiting portion; and / or, The chord length of the swinging part is greater than the chord length of the second limiting part.

[0009] In one possible implementation, the height of the first limiting portion is greater than or equal to the height of the second limiting portion in the direction perpendicular to the straight line of the swing direction.

[0010] In one possible implementation, the first limiting part, the rocking part, and the second limiting part are sequentially distributed in the front-back direction of the nursing chair; and / or, The first limiting part, the swinging part, and the second limiting part are sequentially distributed in the left and right directions of the nursing chair.

[0011] In one possible implementation, the chair frame includes a first side plate, a first connector, and a second side plate. The two ends of the first connector are respectively connected to the first side plate and the second side plate, and enclose a mounting space. The chair body is assembled in the mounting space. Both the first side plate and the second side plate are provided with a first limiting part, a swinging part and a second limiting part.

[0012] In one possible implementation, a first storage bag is provided on the first side panel, the first storage bag being located on the side of the first side panel away from the second side panel; and / or, The second side panel is provided with a second storage bag, which is located on the side of the second side panel away from the first side panel.

[0013] In one possible implementation, the nursing chair further includes armrests that are rotatably disposed on the first side panel and / or the second side panel.

[0014] In one possible implementation, the seat body includes a seat cushion, a backrest, and a second connector, wherein the backrest is connected to the seat cushion at an angle and is connected to the chair frame via the second connector.

[0015] The nursing chair provided in this embodiment includes a chair frame and a seat body disposed on the chair frame. The chair frame includes a first limiting part, a swinging part, and a second limiting part arranged sequentially along its swinging direction. The swinging part has a swinging arc surface in contact with the ground. By adjusting the contact position between the swinging arc surface and the ground, the chair frame can be driven to swing. The curvature of the first limiting part and the second limiting part is greater than the curvature of the swinging part, and both are located on the side of the swinging part closer to the seat body, thus limiting the continued movement of the chair frame in the swinging direction. In this way, the user lying on the seat body can exert force forward, backward, or in other directions according to their own needs, causing the nursing chair to swing back and forth on the swinging arc surface of the chair frame, forming a regular movement to provide a relaxing maternal environment for the baby and help the user soothe the baby to sleep. Furthermore, this embodiment also provides a first limiting part and a second limiting part on both sides of the swinging arc surface to limit the continued swinging of the chair frame, which can prevent the nursing chair from overturning due to excessive swinging and improve the safety of use. Compared to traditional nursing chairs, the nursing chair provided in this application embodiment has a high degree of flexibility in adjusting the chair posture, which can provide a more comfortable feeding posture or daily use posture, resulting in a better user experience.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] In traditional nursing chair designs, the support structure typically uses a fixed rigid frame structure. The contact between the fixed structure and the ground is a single-point static contact. Furthermore, the nursing chair is relatively heavy, which limits its range of motion in the front-back or left-right directions. As a result, when users try to adjust their feeding posture by shifting their center of gravity, it is difficult to adjust both the position of the nursing chair and the user's feeding posture. This makes the nursing chair not only less adaptable and flexible during use, but also requires users to repeatedly adjust their body posture to compensate for feeding positions. Overall comfort is also poor, especially after prolonged use, which can increase discomfort and fail to meet the diverse needs of breastfeeders.

[0023] Please refer to Figures 1 to 4 As shown in the figure, this application embodiment proposes a nursing chair 100, which includes a chair frame 1 and a seat body 2 disposed on the chair frame 1. The chair frame 1 includes a first limiting part 1a, a swinging part 1b and a second limiting part 1c arranged sequentially along its swinging direction. The swinging part 1b has a swinging arc surface 11b in contact with the ground. The chair frame 1 can be driven to swing by adjusting the contact position between the swinging arc surface 11b and the ground. The curvature of the first limiting part 1a and the second limiting part 1c is greater than the curvature of the swinging part 1b, and both are located on the side of the swinging part 1b close to the seat body 2, and can restrict the chair frame 1 from continuing to move in the swinging direction.

[0024] In this embodiment, the nursing chair 100 refers to a chair specifically designed for breastfeeding women, to facilitate their use in scenarios such as physical recovery, infant breastfeeding, and daily rest. The nursing chair 100 includes a chair frame 1 and a seat body 2. The chair frame 1 is the main support structure of the nursing chair 100. The material of the chair frame 1 can be metal, wood, etc. At the same time, the chair frame 1 can be a frame structure composed of trusses, or an integrated platform structure, seat structure, or side panel structure. The seat body 2 is detachably mounted on the chair frame 1. The seat body 2 is in direct contact with the user and can provide the user with a soft cushion, backrest, footrest, etc.

[0025] More specifically, the chair frame 1 includes a first limiting part 1a, a rocking part 1b, and a second limiting part 1c, which are sequentially connected to each other along one direction. The rocking part 1b has a rocking arc surface 11b that contacts the ground. This rocking arc surface 11b serves as the main support surface and can form partial contact with the ground. Simultaneously, the rocking arc surface 11b can continuously change its contact point with the ground, thereby causing the nursing chair 100 to swing within a certain range along a fixed direction. The direction in which the first limiting part 1a, the rocking part 1b, and the second limiting part 1c are sequentially arranged is defined as the rocking direction of the nursing chair 100. The user can actively or passively apply force to make the nursing chair 100 swing along this rocking direction. At this time, the contact position between the rocking arc surface 11b and the ground continuously changes, allowing the nursing chair 100 to adjust its posture and meet the user's needs.

[0026] Furthermore, the first limiting part 1a and the second limiting part 1c are distributed on both sides of the swinging direction of the swinging part 1b. The first limiting part 1a and the second limiting part 1c can limit the swinging part 1b on both sides of the swinging direction, so as to prevent the chair frame 1 from swinging too much and flipping over. At the same time, it also ensures that the user on the seat body 2 will not flip forward or backward excessively, thus improving the safety performance of daily use.

[0027] More specifically, the first limiting part 1a and the second limiting part 1c can be stop structures provided on both sides of the swinging part 1b along the swinging direction, such as limiting blocks, limiting plates, or limiting rods. When the swinging part 1b swings to the maximum angle along the swinging direction, the swinging part 1b abuts against the first limiting part 1a or the second limiting part 1c, or the first limiting part 1a or the second limiting part 1c abuts against the ground to stop the swinging part 1b.

[0028] In a preferred embodiment, the first limiting part 1a and the second limiting part 1c can both have an arc-shaped structure. For example, the first limiting part 1a has a first curved surface on the side facing the ground, and the second limiting part 1c has a second curved surface on the side facing the ground. The first and second curved surfaces are smoothly connected to the rocking arc surface 11b. At the same time, the curvature of the first and second curved surfaces is greater than the curvature of the rocking part 1b. That is, the rocking arc surface 11b has a gentler curvature and a smaller degree of curvature, while the first and second curved surfaces have a larger degree of curvature. When the user forcefully drives the nursing chair 100 to rock from the initial position, the contact position between the rocking arc surface 11b and the ground changes continuously, forming a forward swing. When the rocking arc surface 11b connects to the first or second curved surface, the curvature of the arc structure increases abruptly. To overcome the resistance at this point, additional power is required. Without additional power, the nursing chair 100 will cease movement in that direction. At this time, the line of gravity of the nursing chair deviates from the fulcrum, generating a resisting torque at the fulcrum. Driven by this resisting torque, the nursing chair 100 will move in the opposite direction, forming a backward swing. This process repeats, creating a swinging motion between the first and second curved surfaces. This example aims to increase the resistance to the nursing chair 100's continued forward swing by using the curvature difference between the rocking part 1b and the first limiting part 1a, and between the rocking part 1b and the second limiting part 1c at the transition point. This achieves the purpose of constraining the swinging stroke of the nursing chair 100, thereby improving the controllability and safety of the nursing chair 100's swinging motion.

[0029] The nursing chair 100 provided in this embodiment includes a chair frame 1 and a seat body 2 disposed on the chair frame 1. The chair frame 1 includes a first limiting part 1a, a swinging part 1b, and a second limiting part 1c arranged sequentially along its swinging direction. The swinging part 1b has a swinging arc surface 11b in contact with the ground. By adjusting the contact position between the swinging arc surface 11b and the ground, the chair frame 1 can be driven to swing. The curvature of the first limiting part 1a and the second limiting part 1c is greater than the curvature of the swinging part 1b, and both are located on the side of the swinging part 1b closer to the seat body 2. This can restrict the continued movement of the chair frame 1 in the swinging direction, so that the bottom of the chair frame 1 forms a crescent-shaped arc structure with a flat middle and steep curves at both ends. In this way, the user can exert force forward, backward, or in other directions as needed to drive the nursing chair 100 to move, thereby placing themselves in a comfortable seating environment, facilitating feeding, soothing the baby to sleep, or allowing themselves to relax. The nursing chair 100 provided in this example effectively improves the comfort and adaptability of the nursing chair 100. At the same time, the rocking frequency and rocking angle of the nursing chair 100 can be adjusted at any time according to the user's needs, which is highly flexible and comfortable.

[0030] In one possible implementation, the projection of the center of gravity of the nursing chair 100 falls within the rocking arc surface 11b in the direction perpendicular to the line of the rocking direction.

[0031] It needs to be explained that "perpendicular to the line containing the direction of the sway" refers to the direction perpendicular to the ground. That is, in the direction perpendicular to the ground, the center of gravity of the nursing chair 100 falls within the swaying arc surface 11b. The line of action of the nursing chair 100's gravity and its fulcrum are near the vertical centerline of the swaying arc surface 11b, which provides a resisting torque to help the nursing chair 100 return to its original position when it sways back and forth, thus creating the swaying motion.

[0032] The center of gravity of the nursing chair 100 varies depending on the structure and material of the chair frame 1. For example, the center of gravity of a one-piece chair frame 1 is closer to the ground, while that of a frame-type chair frame 1 is farther from the ground. Furthermore, the structure and weight of the ends of the chair frame 1 along the swing direction also affect the position of the center of gravity. For instance, increasing the mass at the front end of the chair frame 1 along the swing direction will shift the center of gravity towards the front. Additionally, a metal chair frame 1, being heavier, has a center of gravity closer to the ground, while a wooden chair frame 1, being lighter, has a center of gravity farther from the ground. Considering the weight and structure of the chair frame 1, a balanced static position is formed on the side of the chair frame 1 facing the ground. This balanced static position is the position of the chair frame 1 and the nursing chair 100 in a static state, corresponding to the center of gravity. In other words, the balanced static position is the position where the center of gravity is projected vertically onto the ground.

[0033] This example confines the center of gravity projection of the nursing chair 100 within the rocking arc surface 11b, ensuring that the nursing chair 100's balanced static position is always near the vertical midline of the rocking arc surface 11b. This guarantees that the nursing chair 100 can always return to its initial position when stationary, improving stability. At the same time, in motion, the line of gravity of the nursing chair 100 will not deviate from the support boundary of the rocking arc surface 11b, preventing the nursing chair 100 from shifting excessively forward, backward, or in other directions. This avoids the risk of tipping over due to center of gravity shift and also allows users to quickly start within the gently curving rocking arc surface 11b, applying force to the front or rear to rock, improving flexibility and comfort during use and facilitating quick posture adjustments or getting on and off the nursing chair 100.

[0034] In one possible implementation, the distance between the center of gravity of the nursing chair 100 and the lowest point of the rocking arc surface 11b is 11cm to 31cm.

[0035] In this embodiment, the distance between the center of gravity of the nursing chair 100 and the lowest point of the rocking arc surface 11b is limited to between 11cm and 31cm. On the one hand, this ensures that the nursing chair 100 maintains a suitable rocking amplitude, preventing it from tipping over due to excessive rocking amplitude or from having an insufficient rocking amplitude, thus improving safety and comfort. On the other hand, the user can drive the nursing chair 100 to rock by applying a small driving force, reducing the user's effort burden and improving ease of use.

[0036] Specifically, the distance between the center of gravity of the nursing chair 100 and the lowest point of the rocking arc surface 11b is set to 11cm to 31cm, including the 11cm and 31cm at the ends, and can be 15cm, 18cm, 21cm, 25cm, 28cm, 30cm, etc., without limitation. By setting the lower limit of 11cm and the upper limit of 31cm, the center of gravity of the nursing chair 100 is kept within a reasonable range, thereby ensuring that the vertical line of the center of gravity is always within the support area of ​​the arc surface contact point. Within this range, the nursing chair 100 can not only maintain high static and dynamic stability, but also drive the nursing chair 100 to rock without the user applying too much external force. Moreover, the rocking amplitude of the nursing chair 100 during the rocking process is also within a reasonable and safe range, which can effectively improve the user's comfort.

[0037] In a preferred embodiment, the distance between the center of gravity of the nursing chair 100 and the lowest point of the rocking surface 11b is 21 cm. This distance ensures good stability of the nursing chair 100 during rocking, while providing a moderate rocking amplitude, allowing the user to easily drive the nursing chair 100 to rock with minimal external force. Specifically, when the user sits on the nursing chair 100, the center of gravity of the nursing chair 100 is slightly higher than the lowest point of the rocking surface 11b, ensuring the chair remains balanced when stationary. When the user slightly moves their body, the chair will rock accordingly, but due to the distance between the center of gravity and the lowest point of the rocking surface 11b, the overall rocking amplitude will not be excessive, and the rocking motion is controllable.

[0038] In one possible implementation, the chord length of the swing portion 1b is greater than the chord length of the first limiting portion 1a; alternatively, the chord length of the swing portion 1b is greater than the chord length of the second limiting portion 1c.

[0039] In this embodiment, the first curved surface of the first limiting part 1a and the second curved surface of the second limiting part 1c are both arc surfaces with a certain curvature. The chord length of the rocking part 1b is defined as the straight-line distance between the two farthest points of the rocking arc surface 11b. The chord lengths of the first limiting part 1a and the second limiting part 1c are measured in the same way. That is, the chord length of the first limiting part 1a is the straight-line distance between the end of the first curved surface connected to the rocking arc surface 11b and the end away from the rocking arc surface 11b, and the chord length of the second limiting part 1c is the straight-line distance between the end of the second curved surface connected to the rocking arc surface 11b and the end away from the rocking arc surface 11b.

[0040] When the nursing chair 100 is rocked, the long-chord-length rocking arc surface 11b provides a greater rocking stroke, making the rocking amplitude smoother and gentler. Meanwhile, the first limiting part 1a and the second limiting part 1c, with their larger curvature and shorter chord length, can form a converging and enveloping area at the front or rear of the chair frame 1, causing the chair frame 1 to gradually deviate from the ground, further enhancing the limiting effect. This example, through this chord length difference design, allows the nursing chair 100 to significantly improve its rocking adjustment freedom while maintaining its limiting function, enabling the nursing chair 100 to achieve a greater swing amplitude during rocking, while simultaneously ensuring ease of operation and safety.

[0041] In one possible implementation, such as Figure 4 As shown, in the direction perpendicular to the straight line of the swing direction, the height of the first limiting part 1a is greater than or equal to the height of the second limiting part 1c.

[0042] This embodiment uses the rocking direction as the front-to-back direction as an example, meaning that the nursing chair 100 rocks forward or backward during use. Here, "perpendicular to the line containing the rocking direction" refers to the vertical direction perpendicular to the ground. The height of the first limiting part 1a is defined as H1, and the height of the second limiting part 1c is defined as H2. H1 is greater than or equal to H2, meaning the height of the first limiting part 1a at the front end is greater than or equal to the height of the second limiting part 1c at the rear end.

[0043] In one example, the length of the first limiting part 1a in the swing direction can be greater than or equal to the length of the second limiting part 1c in the swing direction. At the same time, the curvature or tilt angle of the first limiting part 1a can also be greater than or equal to the curvature or tilt angle of the second limiting part 1c, so as to ensure that the height of the first limiting part 1a is greater than the height of the second limiting part 1c.

[0044] In actual use, driven by life experience or inertia, users generally move the nursing chair 100 forward first. Thus, when the chair frame 1 swings towards the first limiting part 1a, the higher first limiting part 1a provides greater forward resistance, thereby enhancing the limiting and stopping effect of the chair frame 1 at the first limiting part 1a, preventing the nursing chair 100 from moving further forward and preventing the chair frame 1 from tilting forward. Conversely, when swinging in the opposite direction, the lower height of the second limiting part 1c allows for a smooth transition of the center of gravity when the chair frame 1 moves backward. Furthermore, ensuring a higher height for the front end of the chair frame 1 allows the overall center of gravity of the nursing chair 100 to shift backward when rocking back and forth, further preventing the nursing chair 100 from tilting forward. This makes it more suitable for feeders to feed their babies in a lying position and for rocking the nursing chair 100 to soothe their babies to sleep while lying down. Therefore, the height difference between the first limiting part 1a and the second limiting part 1c not only limits the forward tilt of the nursing chair 100, but also avoids swaying caused by sudden changes in resistance when tilting backward. This ensures that the chair frame 1 maintains torque balance on the axis perpendicular to the swaying direction, prevents the nursing chair 100 from overturning, and improves the comfort of use while ensuring the overall stability of the nursing chair 100.

[0045] In one possible implementation, such as Figures 1 to 4 As shown, the first limiting part 1a, the rocking part 1b, and the second limiting part 1c are sequentially distributed in the front-back direction of the nursing chair 100. And / or, the first limiting part 1a, the rocking part 1b, and the second limiting part 1c are sequentially distributed in the left-right direction of the nursing chair 100.

[0046] In this embodiment, the seat body 2 includes a seat cushion and a backrest 22. The backrest 22 and the seat cushion together form a seat, allowing a user to enter the seat and lean against the backrest 22. The seat cushion and / or backrest 22 are mounted on the chair frame 1. The backrest 22 leaning against is defined as the rear, and the direction the user faces is forward. The user's left and right hands are positioned to the left and right, respectively. Thus, the chair frame 1 can swing back and forth, or swing left and right in the seat body 2, or simultaneously in both directions.

[0047] Specifically, the first limiting part 1a, the rocking part 1b, and the second limiting part 1c can be arranged sequentially along the front-back direction of the nursing chair 100, so that the chair frame 1 can swing in the front-back direction. At this time, the rocking part 1b forms a rocking path in the front-back direction, and the chair frame 1 can be limited by the first limiting part 1a at the front end (rear end) and by the second limiting part 1c at the rear end (front end), so as to prevent the chair frame 1 from tilting too far forward or backward in the front-back direction.

[0048] Alternatively, the first limiting part 1a, the rocking part 1b, and the second limiting part 1c can be arranged sequentially along the left and right directions of the nursing chair 100, so that the chair frame 1 can swing in the left and right directions. In this case, the rocking part 1b forms a rocking path in the left and right directions, and the chair frame 1 can be limited by the first limiting part 1a at the left end (right end) of the nursing chair 100 and by the second limiting part 1c at the right end (left end), so as to prevent the chair frame 1 from tilting excessively in the left and right directions.

[0049] Alternatively, the first limiting part 1a and the second limiting part 1c can be simultaneously set in the front-back direction and the left-right direction of the nursing chair 100. In this case, the rocking part 1b is set in the middle of the nursing chair and is surrounded by the first limiting part 1a and the second limiting part 1c, so that the chair frame 1 can swing in the front-back and left-right directions with greater freedom and flexibility.

[0050] It is understood that the nursing chair 100 in this embodiment can swing in the front-back direction and / or the left-right direction. When the user needs to swing in the front-back direction, the first limiting part 1a, the swinging part 1b, and the second limiting part 1c of the chair frame 1 are arranged sequentially in the front-back direction and the swinging part 1b contacts the ground. The front-back swing is achieved by changing the contact position of the swinging arc surface 11b. At this time, the first limiting part 1a and the second limiting part 1c limit the displacement of the chair frame 1 at both ends of the front-back movement path. When the user needs to swing in the left-right direction, the chair frame 1 switches to the swinging part 1b arranged in the left-right direction. The lateral swing is achieved by changing the contact position of the swaying arc surface 11b. The corresponding first limiting part 1a and second limiting part 1c provide displacement constraints at the ends of the left and right movement paths. This design allows the nursing chair 100 to be adapted to the space of the usage environment and to meet the different breastfeeding posture needs of the user. This allows the nursing chair 100 to flexibly select a single forward and backward direction, a single left and right direction, or a combination of forward, backward, left and right directions, effectively improving the adaptability of the nursing chair 100 to different scenarios and enhancing its adaptability and comfort.

[0051] In one possible implementation, such as Figure 3 As shown, the chair frame 1 includes a first side plate 11, a first connecting member 12 and a second side plate 13. The two ends of the first connecting member 12 are respectively connected to the first side plate 11 and the second side plate 13, and enclose to form an installation space 14. The seat body 2 is assembled in the installation space 14. A first limiting part 1a, a rocking part 1b and a second limiting part 1c are provided on the first side plate 11 and the second side plate 13.

[0052] In this embodiment, the first side plate 11 and the second side plate 13 can be plate-like structures, platform structures, seat structures, or frame structures, and are not limited thereto. The first side plate 11 and the second side plate 13 are arranged relatively apart and parallel to each other. The first connecting member 12 can be a connecting rod, connecting column, connecting plate, or connecting frame, etc., and can be set between the first side plate 11 and the second side plate 13 by means of mortise and tenon connection, insertion, or welding, so that the chair frame 1 forms a near "H"-shaped symmetrical support structure. The upper part of the first connecting member 12 and the upper parts of the corresponding first side plate 11 and the second side plate 13 enclose an installation space 14, and the seat body 2 is set on the installation space 14; at this time, the first side plate 11 and the second side plate 13 are located on both sides of the seat body 2, and can limit the seat body 2 on the left and right sides.

[0053] Furthermore, the first side plate 11 is provided with a first limiting part 1a, a swinging part 1b, and a second limiting part 1c, and the second side plate 13 is provided with the same first limiting part 1a, swinging part 1b, and second limiting part 1c. The first connecting member 12 can be provided on the two second limiting parts 1c. Simultaneously, the first limiting part 1a, swinging part 1b, and second limiting part 1c on the first side plate 11 and the second side plate 13 are arranged in pairs correspondingly. This allows the first side plate 11 and the second side plate 13 located on both sides of the seat body 2 to swing and limit synchronously, ensuring the stability of the seat body 2 during swinging. In this example, the two side plates are symmetrically arranged to ensure that the force on both sides is balanced when the chair frame 1 swings in the front-back or left-right directions, avoiding the possibility of the nursing chair 100 tipping over due to unilateral force.

[0054] In one possible implementation, such as Figures 1 to 4 As shown, a first storage bag 111 is provided on the first side panel 11, and the first storage bag 111 is located on the side of the first side panel 11 away from the second side panel 13. And / or, a second storage bag 131 is provided on the second side panel 13, and the second storage bag 131 is located on the side of the second side panel 13 away from the first side panel 11.

[0055] In this embodiment, to increase storage space, a first storage bag 111 is provided on the side of the first side panel 11 away from the second side panel 13, and / or a second storage bag 131 is provided on the side of the second side panel 13 away from the first side panel 11. The first storage bag 111 and the second storage bag 131 can be independent bag bodies, which can be made of flexible fabric, waterproof fabric, leather, or plastic products, etc., without limitation, so that the first storage bag 111 can be set on the outer surface of the first side panel 11 by sewing or gluing, or the second storage bag 131 can be set on the outer surface of the second side panel 13 by sewing or gluing.

[0056] When a user is breastfeeding while seated on the main body 2, bottles, tissues, diapers, and other cleaning supplies can be stored in the first storage bag 111 and / or the second storage bag 131 with one hand. The first storage bag 111 and the second storage bag 131 extend the auxiliary functions of the side panel structure, solving the problem of inconvenient storage of items during breastfeeding, while avoiding interruptions to the breastfeeding process due to repeated getting up, thus improving the overall convenience and comfort of the breastfeeding chair 100.

[0057] In one possible implementation, such as Figures 1 to 4 As shown, the nursing chair 100 also includes armrests 3, which are rotatably mounted on the first side panel 11 and / or the second side panel 13.

[0058] In this embodiment, the nursing chair 100 also includes armrests 3, which serve as support members or other support structures to provide support for the user's elbows. The armrests 3 can be block-shaped, strip-shaped, plate-shaped, or irregularly shaped. One end, such as the bottom end, can be connected to the outer wall of the first side panel 11 and / or the second side panel 13 via a pivot joint, while the other end, such as the top end, forms a bearing surface to support the user's elbows. The length dimension of the armrest 3 is greater than its width dimension, which can adapt to the shape of the user's arm, increase the contact area between the arm and the armrest 3, disperse the supporting stress between the arm and the armrest 3, improve user comfort, and enhance the support stability of the armrest 3. Furthermore, to further improve user comfort, the surface of the armrest 3 can be covered with soft materials such as leather, soft cloth, or soft fur.

[0059] More specifically, the armrest 3 can be individually mounted on the first side panel 11 or the second side panel 13 to provide support for the user's elbow on one side when breastfeeding or soothing the baby to sleep, allowing the user to adjust to the optimal and most comfortable posture. In other embodiments, the armrest 3 can also be mounted on both the first side panel 11 and the second side panel 13 simultaneously, that is, the armrest 3 is mounted on both sides of the seat body 2. The user can choose to adjust one side individually to support the elbow, or adjust both sides to support the elbow, thereby improving the overall usability of the nursing chair 100.

[0060] The rotating connection refers to an assembly method that allows the handrail 3 to rotate relative to the first side plate or the first side plate 11 around a fixed axis. The mating method can be a rotating shaft and rotating hole, a rotating groove and rotating column, a ball joint, a pin rotation connection, or a hinge rotation connection, etc., and is not limited here. Specifically, a rotating cavity is provided on the top of the first side plate 11 (the side facing away from the rocking arc surface 11b) and / or the top of the second side plate 13 (the side facing away from the rocking arc surface 11b). A rotating component is provided on the bottom wall of the rotating cavity, and the rotating component has a rotating groove. One side of the pivot is connected to the handrail 3, and the other side of the pivot extends into the rotating groove and rotates with the rotating component to achieve rotation of the handrail 3 relative to the first side plate 11 and / or the second side plate 13.

[0061] This example demonstrates how a rotatable armrest 3 can be quickly adjusted to multiple angles, solving the problem of limited breastfeeding posture caused by the fixed position of the armrest 3 in traditional breastfeeding chairs. This breastfeeding chair armrest 3 can adapt to the diverse needs and daily habits of feeders, allowing them to quickly and flexibly adjust their feeding posture, effectively improving the comfort and adaptability of the breastfeeding chair 100. Furthermore, the frequency and angle can be adjusted as needed, providing relaxation and even helping to soothe infants to sleep during breastfeeding, maintaining a natural and comfortable breastfeeding posture.

[0062] In one possible implementation, such as Figures 2 to 4 As shown, the seat body 2 includes a seat cushion 21, a backrest 22 and a second connector 23. The backrest 22 is connected to the seat cushion 21 at an angle and is connected to the chair frame 1 through the second connector 23.

[0063] In this embodiment, the seat cushion 21 is the bottom support structure of the seat body 2. The seat cushion 21 can be composed of high-density sponge material, latex material, cotton material, etc., or it can be formed by a combination of multiple materials. At the same time, the seat cushion 21 may also include springs to combine with the above-mentioned high-density sponge, latex and cotton materials to form the seat cushion 21. There is no limitation here.

[0064] In addition, the seat body 2 also includes a backrest 22, which is connected to the seat cushion 21, such as a fixed connection, a movable connection, or a detachable connection. In a specific example, the backrest 22 and the seat cushion 21 can be movably connected, such as a rotatable connection, so that the backrest 22 can rotate relative to the seat cushion 21, thereby adjusting the angle between the backrest 22 and the seat cushion 21. The angle between the seat cushion 21 and the backrest 22 can be set from 90° to 180° to accommodate different sitting postures. The backrest 22 and the seat cushion 21 enclose a seating space, where the user can enter the seating space and sit on the seat cushion 21. If necessary, the user can also lean on the backrest 22, so that the seat cushion 21 and the backrest 22 can jointly support the user.

[0065] Furthermore, the seat body 2 also includes a second connector 23. The second connector 23 uses a rigid material to fix the overall structure formed by the seat cushion 21 and the backrest 22 within the installation space 14 of the chair frame 1. The second connector 23 can be a connecting rod, connecting column, connecting plate, or connecting frame, etc. By setting the second connector 23, the rigidity and stiffness of the seat body 2 and the nursing chair 100 can be increased, the overall support of the nursing chair 100 can be enhanced, and the support for the user can be improved.

[0066] The second connector 23 can be connected to the first connector 12 of the movable part, such as by bolt connection, snap connection, tenon and mortise connection, to ensure that the seat body 2 does not undergo relative displacement during the rocking process.

[0067] In one example, the seat cushion 21 and backrest 22 are connected at an angle to form a stable angled support structure. The second connector 23 fixes the overall structure formed by the seat cushion 21 and backrest 22 within the installation space 14 enclosed by the side panels of the chair frame 1. When the chair frame 1 swings back and forth or left and right through the rocking part 1b, the angled structure formed by the seat cushion 21 and backrest 22 can maintain the stability of the user's sitting posture. The second connector 23 restricts the relative movement between the seat body 2 and the chair frame 1 through a rigid connection. For example, the second connector 23 uses a four-point fixing method to lock the bottom of the seat cushion 21 to the first connector 12 of the chair frame 1. During the rocking process, the kinetic energy generated by the swinging of the chair frame 1 is transmitted to the first connector 12 through the second connector 23 and connected to the seat body 2 through the first connector 12, so that the seat cushion 21 and backrest 22 swing synchronously and maintain a constant relative position. This structure can quickly respond to the user's posture adjustment needs and avoid the failure of body support during breastfeeding due to the shaking of the seat body 2.

[0068] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
