[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0041] Example 1

[0042] like Figure 1 and Figure 2 As shown, this embodiment discloses a backrest assembly, which includes an upper backboard 1 and a lower backboard 2. In this embodiment, the upper backboard 1 and the lower backboard 2 are connected and assembled together by a fixed connection method such as riveting to form the backrest assembly.

[0043] In other alternative embodiments, the upper back plate 1 and the lower back plate 2 may also be connected and assembled together by a detachable connection such as screw connection to form a backrest assembly.

[0044] Among them, Figure 1 and Figure 2 As shown, in the up and down direction in the figure, the upper back plate 1 and the lower back plate 2 are assembled together.

[0045] In the present embodiment, the backrest assembly is a two-stage type, and the lower back plate 2 is an integrally formed structure. The upper back plate 1 can be assembled with the lower back plate 2 in different styles as needed. The lower back plate 2 is produced by a separate mold to adapt to the specific structure of a certain vehicle model, thereby ensuring that the lower back plate 2 can be adapted to the vehicle model, and further ensuring that after the upper back plate 1 is assembled to the lower back plate 2 to form the backrest assembly, the backrest assembly can be installed on the vehicle model. Moreover, when the backrest assembly needs to be installed on another vehicle model, it is only necessary to mold and manufacture the lower back plate 2 separately to adapt to the specific structure of the vehicle model. Therefore, the backrest assembly of the present embodiment has high applicability, and since the volume of the lower back plate 2 is smaller than the volume of the entire backrest assembly, it can also reduce the mold cost, thereby saving production costs.

[0046] Specifically, the upper back panel 1 in this embodiment is provided with a connecting portion 11 at one end close to the lower back panel 2, and a corresponding connecting portion 21 matching the connecting portion 11 is provided at a position on the lower back panel 2 connected to the upper back panel 1. After the connecting portion 11 and the corresponding connecting portion 21 are overlapped together, a connecting and fixing hole passing through the connecting portion 11 and the corresponding connecting portion 21 is provided at the overlapping connecting position of the two, and a rivet is installed in the connecting and fixing hole to fix the upper back panel 1 and the lower back panel 2 together, or a screw is installed in the connecting and fixing hole to detachably connect the upper back panel 1 and the lower back panel 2 together.

[0047] In this embodiment, a connecting component 22 is provided at one end of the second backrest away from the first backrest. The connecting component 22 is used to install the backrest assembly to the required position of a specific vehicle model. The connecting component is connected to other devices by means of axial rotation. The form of the connecting component 22 can be flexibly selected according to the needs of the vehicle model.

[0048] like Figure 1-Figure 4As shown, in this embodiment, the connection assembly 22 is a pair of connection rings symmetrically arranged on both sides of the lower back plate 2, and the connection rings can be put on the connection structure at the required position of a specific vehicle model.

[0049] like Figure 5 As shown, in other alternative embodiments, the connection assembly 22 is a pair of connection shafts symmetrically arranged on both sides of the lower back plate 2, and the connection shafts can be plugged into other devices. The other device can be, for example, a connection structure of a baby stroller of a specific model, but is not limited thereto, and can also be other suitable devices.

[0050] Example 2

[0051] The difference between this embodiment and embodiment 1 is that:

[0052] like Figure 2 and Figure 3 As shown, in the embodiment, the backrest assembly is of three sections, specifically, a connection portion 11 is provided at one end of the upper back panel 1 close to the lower back panel 2, the lower back panel 2 includes a left lower back panel 23 and a right lower back panel 24, a left corresponding connection portion 231 is provided on the left lower back panel 23, and the left corresponding connection portion 231 is connected to the left side of the connection portion 11, and a right corresponding connection portion 241 is provided on the right lower back panel 24, and the right corresponding connection portion 241 is connected to the right side of the connection portion 11.

[0053] In this embodiment, the above-mentioned structural form is adopted to further save costs.

[0054] Other similarities will not be repeated here.

[0055] Example 3

[0056] like Figure 6 As shown, this embodiment also discloses a baby stroller, the seat of which can rotate. Figure 1-Figure 4 Backrest assembly shown.

[0057] Example 4

[0058] like Figure 7 As shown, this embodiment also discloses another baby stroller, the seat of which is fixed in direction and cannot be rotated. Figure 5 Backrest assembly shown.

[0059] Example 5

[0060] like Figure 8 As shown, this embodiment also discloses a method for producing a backrest assembly, the method comprising the following steps:

[0061] S1, manufacturing a first mold according to the shape of the upper back plate 1;

[0062] S2, using the first mold to manufacture the upper back plate 1;

[0063] S3, manufacturing a second mold according to the shape of the lower back plate 2;

[0064] S4, using the second mold to manufacture the lower back plate 2;

[0065] S5, assembling the upper back plate 1 and the lower back plate 2 together to form a backrest assembly.

[0066] When the method of this embodiment is used to produce the backrest assembly, it is only necessary to mold and manufacture the lower back panel separately according to the specific structure of the vehicle model. Moreover, since the volume of the lower back panel is smaller than the volume of the entire backrest assembly, the mold making cost can be reduced, thereby saving production costs.

[0067] It should be understood that, although the steps in the flowchart are shown in sequence as indicated by the arrows, these steps are not necessarily executed in sequence in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a portion of the steps in the accompanying drawings may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least a portion of the sub-steps or stages of other steps.

[0068] It should be noted that in the claims and description of this patent, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one" do not exclude the existence of other identical elements in the process, method, article or device including the elements.
