[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0029] Example 1: As Figure 1 - Figure 8 As shown, this utility model provides an adjustable folding seat, including an upper seat frame 1, a lower seat frame 2, and a base mechanism 6. A joint mechanism 4 is provided between the upper seat frame 1, the lower seat frame 2, and the base mechanism 6. The joint mechanism 4 includes joints A41, B42, C45, and D49. Joint B42 is connected to the lower seat frame 2, joint C45 is connected to the upper seat frame 1, and joint D49 is connected to the base mechanism 6. A locking tongue A44 is provided between joints B42 and C45, which controls the locking and unlocking of joints B42 and C45. A locking tongue B47 is provided between joints C45 and D49, which controls the locking and unlocking of joints C45 and D49.
[0030] The specific settings and functions of this embodiment are described below: The entire seat is installed on the stroller seat through the base mechanism 6. The stroller seat moves through the pulleys at the bottom. A seat cover is provided above the seat for sun and rain protection. A seat cover is provided below the seat for weight support. Cotton fabric can be added above the seat cover to improve the comfort of the baby.
[0031] The three-position seat angle adjustment is achieved through the coordination of various joints, as shown in the attached diagram. Figure 7As shown, the seat changes from first position to second position to third position to folded position. Adjusting the position requires locking joints B42 and C45, unlocking joints C45 and D49, and rotating joint C45 relative to turntable 46. Folding the seat requires unlocking joints B42 and C45, rotating them 180 degrees. The outer wall of the latch A44 has multiple teeth, and the inner cavities of joints B42 and C45 have grooves corresponding to the shape of the latch A44. The latch A44 has two position states within the cavity formed by joints B42 and C45. When in the middle position, the latch A44... When locked to the toothed grooves of joints B42 and C45 respectively, in the left position, the locking tongue A44 is locked only in the toothed groove of joint B42 and unlocked from joint C45. Similarly, the locking tongue B47 in the cavity formed by joints C45 and D49 also has two position states. In the middle position, the locking tongue B47 is locked to the toothed grooves of joints C45 and D49 respectively. In the right position, the locking tongue B47 is locked only in the toothed groove of joint D49 and unlocked from joint C45. When adjusting the gear, joints B42 and C45 are locked and joints C45 and D49 are unlocked. When folding the seat, joints B42 and C45 are unlocked.
[0032] Example 2: Figure 4 , Figure 8 As shown, an adjustable folding seat cushion shock absorption structure is provided. The base mechanism 6 includes a socket 61 and an insertion port 62. An anti-vibration device 63 is provided inside the insertion port 62, and the socket 61 is inserted into the insertion port 62.
[0033] In this embodiment, the base mechanism 6 is designed as a split structure, wherein the socket 61 is rigidly connected to the seat, the plug 62 is rigidly connected to the stroller seat below, and the plug 62 is provided with a shock absorber 63 inside, which includes but is not limited to springs, foam and other cushioning materials, which can reduce the impact of the stroller's vibration on the seat during movement.
[0034] Example 3: Figure 5 , Figure 6 and Figure 8 As shown, a guardrail 3 is installed on one side of joint A41, and a protruding tongue is provided on the other side of joint A41. An annular guide slope is provided on the side of joint C45. A column is provided on the side of joint B42, and a locking tongue A44 is rotatably connected to the column. A compression spring A43 is provided between joint B42 and locking tongue A44, and the compression spring A43 is installed on the axis of column A1.
[0035] A turntable 46 is provided between joint C45 and locking tongue B47. An annular inclined block I is provided on the side wall of joint C45, and an annular guide ramp II is provided on the side wall of turntable 46. There are three sets of annular inclined blocks I on joint C45 and annular guide ramp II on turntable 46. The mating positions of annular inclined blocks I and annular guide ramp II correspond to the three positions of the seat pocket.
[0036] A compression spring B48 is provided between the locking tongue B47 and the joint D49. A second post is provided on the side wall of the joint D49, and an annular guide ramp three is provided on the second post. An annular inclined block two is provided on the side wall of the locking tongue A44. A push-button is provided on the outer wall of the socket 61, and a multi-level buckle groove is provided on the outer wall of the insertion port 62. A handle 5 is fixedly connected to the outer wall of the upper bracket 1.
[0037] The overall effect of this embodiment is that, in addition to the upper frame 1, lower frame 2 and base mechanism 6, the seat is also equipped with a guard frame 3 and a handle 5. The guard frame 3 is used to protect the baby from accidentally falling out while playing in the seat. The handle 5 makes the folding process of the seat easier. Since the tongue is connected to the outside of joint A41, an arc groove is provided on joint B42 so that the tongue passes through joint B42 and contacts the annular guide slope on joint C45. The annular guide slope has a slope. By rotating joint A41, joint A41 is pushed outward during the sliding of the tongue, so that joint A41 and joint B42 move away from joint C45 together. Joint B42, along with the locking tongue A44, disengages from joint C45, thus unlocking. When locking, simply rotate joint A41 in the opposite direction.
[0038] The locking and unlocking of latch B47 is achieved through the cooperation of latch A44 and joint D49, as shown in the appendix. Figure 6 As shown, rotate joint D49 clockwise to bring the second annular inclined block and the third annular guide ramp into contact, and push open the second column. At this time, the locking tongue B47 disengages from joint C45, thus achieving the unlocking effect of joint C45 and joint D49. Joint C45 can rotate relative to joint D49. The first annular inclined block and the second annular guide ramp are unlocked in one direction. Rotating joint C45 clockwise can disengage the inclined block from the guide ramp until it rotates 120 degrees and engages again, allowing the turntable 46 and joint C45 to be adjusted in three positions. When locking, rotate joint D49 to the initial position to re-lock the locking tongue B47 in joint C45.
[0039] The usage and working principle of this device: When adjusting the seat position, rotate joint D49 clockwise to make the second annular inclined block and the third annular guide slope contact each other, and push the second column open. At this time, the locking tongue B47 disengages from joint C45, thus achieving the unlocking effect of joint C45 and joint D49. Joint C45 can rotate relative to joint D49. Rotating joint C45 clockwise by 120 degrees can achieve the switching of different positions.
[0040] When folding the seat, rotate joint A41. During the sliding of the tongue, push joint A41 outward so that joint A41 and joint B42 move away from joint C45 together. Joint B42, along with the locking tongue A44, disengages from joint C45. Rotate joint B42 and joint C45 180 degrees so that the upper frame 1 and lower frame 2 fold together.
[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
