When a component is referred to as being “disposed on” another component, it can be directly disposed on the other component or there can be a middle component.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items.

[0041] Reference is made to the accompanying drawings that form a part of this disclosure. Figure 1 Reference is made to the accompanying drawings that form a part of this disclosure. Figure 8 As shown in the accompanying drawings, the present application discloses a sunshade height-adjustable stroller seat, comprising:

[0042] The seat frame 100 includes a seat plate 110 for sitting and two backrest rods 120 respectively connected to both sides of the seat plate 110;

[0043] Two sliding seats 200 are slidably mounted on each backrest rod 120;

[0044] The two ends of the shed rod 300 are respectively connected to the sliding seats 200, and the shed rod 300 is provided with a sunshade (not shown);

[0045] The locking member 400 is disposed in the backrest rod 120 and has a locking position extending out of the outer circumference of the backrest rod 120 (see the attached FIG. Figure 8 The locking member 400 is linked to an elastic member 410, which is used to keep the locking member 400 in the locked position. In the locked position, the locking member 400 limits the movement of the sliding seat 200 relative to the backrest rod 120; in the extension direction of the backrest rod 120, the sliding seat 200 is driven by an external force to cause the locking member 400 to overcome the elastic force of the elastic member 410 and enter the avoidance position.

[0046] The backrest rod 120 can be directly fixed to the seat plate 110, or it can be movably arranged on the seat plate 110 through a rotating mechanism. The backrest rod 120 provides a track extending in the height direction for the sliding seat 200 to cooperate with. Therefore, the awning in the present application can freely adjust the relative position of the awning on the scale of the backrest rod 120, and compared with the existing technology, it can achieve a multi-dimensional and large-stroke adjustment range. Compared with the technical solution that requires the awning to be disassembled for adjustment, the awning adjustment process in the present application is more convenient and improves the user experience. At the same time, compared with the non-adjustable awning, the sliding seat 200 itself does not add any additional adaptation structure, and the structure is simple and compact, which is convenient for production and assembly.

[0047] See attached Figure 2 To the attached Figure 6 In the illustrated embodiment, the sliding seat 200 includes a main body 210 slidably arranged on the backrest rod 120 and a first connecting portion 220 and a second connecting portion 230 arranged on the main body 210. The awning rod 300 includes a fixed rod 310 fixedly connected to the first connecting portion 220 and a movable rod 320 hinged to the second connecting portion 230. The movable rod 320 moves relative to the fixed rod 310 to open or close the awning. Figure 4 and Figure 5In the embodiment, the first connecting portion 220 is a plug-in hole provided on the main body 210, and the fixed rod 310 is inserted into the plug-in hole and connected by bonding, clamping, welding, interference fit, etc. The second connecting portion 230 is a first adapting structure extending outward from the main body 210, and the end of the movable rod 320 is provided with a second adapting structure that rotates with the rotating adapting structure. The two can rotate with each other under the action of external force and maintain their relative positions in a free state. The specific structure can be implemented in combination with the figures or other existing technologies. The fixed rod 310 and the movable rod 320 are U-shaped, and the two ends of the U-shaped opening are respectively connected to different sliding seats 200.

[0048] In terms of the specific structure of the sliding seat 200, the main body 210 has a C-shaped cross-section and covers the circumference of the backrest rod 120. The interior of the C-shape is a sliding cavity 211 that constrains the backrest rod 120. The distance between the two ends of the C-shaped opening is smaller than the outer diameter of the backrest rod 120. The C-shaped openings of the two sliding seats 200 are arranged opposite each other. Furthermore, the sliding cavity 211 is open at both ends and has a non-circular cross-section; the backrest rod 120 passes through and slides in the sliding cavity 211, and the outer periphery of the backrest rod 120 is in contact with the inner wall of the sliding cavity 211. Figure 4 As shown, the cross-section of the sliding cavity 211 and the backrest rod 120 is elliptical. This structure ensures smooth sliding while preventing the sliding seat 200 from rotating circumferentially around the backrest rod 120, thereby maintaining the structural integrity of the awning. Furthermore, the backrest rod 120 is provided with a guide groove 121 extending in the axial direction of the backrest. A sliding block 212 is provided on the inner wall of the sliding cavity 211 to engage with the guide groove 121. The sliding engagement between the sliding block 212 and the guide groove 121 is parallel to the sliding engagement between the sliding cavity 211 and the backrest rod 120. This coordination further enhances the smoothness and stability of the sliding of the sliding seat 200 and the backrest rod 120. Specifically, the sliding block 212 extends from the sidewall of the sliding cavity 211 into the cavity 211, with its end enlarged to form a stopper 213. The cross-section of the guide groove 121 is adapted to accommodate the sliding block 212. The opening size of the guide groove 121 is smaller than the limit portion 213, which can limit the sliding block 212 from escaping from the guide groove 121. In order to reduce the impact of each groove body on the difficulty of component production, the backrest rod 120 is obtained from a hollow profile, and the profile can easily obtain a groove body extending in the axial direction during the processing. Figure 4 In the embodiment, the backrest rod 120 is provided with a slot exposed to the peripheral surface, and the opening position of the slot corresponds to the opening of the C-shaped cross-section of the body 210 .

[0049] The sliding of the sliding seat 200 is achieved by the backrest rod 120, and the positioning of the sliding seat 200 is achieved by the locking member 400. Figure 1 , Attachment Figure 2 , Attachment Figure 7 And attachedFigure 8 In the illustrated embodiment, a locking hole 122 is provided on the backrest rod 120 for the locking member 400 to extend out and enter the locked position. The locking members 400 are arranged in groups, and each group of locking members 400 includes two locking members 400 and is respectively arranged on a different backrest rod 120. The locking members 400 in the same group are at the same height. There are multiple groups of locking members 400. In the extension direction of the backrest rod 120, the distance between two adjacent groups of locking members 400 is greater than or equal to the length of the sliding seat 200. In the figure, there are two groups of locking members 400, which are divided into a first group located at the top and a second group located at the bottom in the height direction. The sliding seat 200 has a first position (for example, attached to the first position) higher than the first group of locking members. Figure 8 (as shown), a second position between the first and second sets of locking members, and a third position below the second set of locking members. As shown in the figure, the backrest rod 120 is further provided with a first retaining ring 123 positioned above the first set, and a second retaining ring 124 positioned below the second set. The distance between the first retaining ring 123 and the first set of locking members 400 is greater than or equal to the length of the sliding seat 200. Similarly, the distance between the second retaining ring 124 and the second set of locking members 400 is greater than or equal to the length of the sliding seat 200.

[0050] In addition to the matching arrangement shown in the figure, positioning holes corresponding to the positions of the locking members 400 can also be provided within the sliding cavity 211. That is, the sliding seat 200 can also have a fourth position where it rests on the first set of locking members and a fifth position where it rests on the second set of locking members. Based on this concept, the number of positioning holes can be further increased to provide more resting positions.

[0051] In order to provide a smoother driving experience, see the attached Figure 5 , Attachment Figure 6 And attached Figure 8 In the illustrated embodiment, inclined guide surfaces 240 are provided on the upper and lower ends of the sliding seat 200, corresponding to the position of the locking member 400. These inclined guide surfaces 240 are used to compress the locking member 400 and force it into the retracted position, overcoming the elastic force of the elastic member 410. The side edges of the inclined guide surfaces 240 smoothly transition to the end surface of the sliding seat 200 and the inner wall of the sliding cavity 211, respectively.

[0052] In the attached Figure 8 In the embodiment, the elastic member 410 is a U-shaped member, and the locking member 400 is a columnar structure at one open end of the U-shaped member. In this embodiment, the elastic member 410 and the locking member 400 are an integral structure. In other embodiments, the two can be separate structures, and the specific structure of the elastic member 410 can also be implemented with reference to existing technologies.

[0053] Combined with the above and see the attached Figure 9As shown, the application also discloses a child carrier, which comprises a frame 900 and the sunshade height-adjustable stroller seat in the application, and the stroller seat is installed on the frame 900. The sunshade height-adjustable stroller seat is described above, and the connection part of the stroller seat and the frame 900 and the frame 900 part can be combined with the prior art, for example, the stroller seat can be rotated relative to the frame 900, and the frame 900 can be folded, and the like, which will not be described here.

[0054] The technical features of the above-mentioned embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered as the scope disclosed in the specification. When the technical features in different embodiments are embodied in the same figure, it can be considered that the figure also discloses the combination of each embodiment involved.

[0055] The above-mentioned embodiments only express several implementation manners of the application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the application, some modifications and improvements can be made, which are all within the protection scope of the application.
