[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] like Figures 1-4 As shown, this application embodiment provides a seat back, including a backrest body, a fan module, and a snap-fit ​​component 1; the backrest body has a backrest spring frame inside, the backrest spring frame includes multiple connected spring wires; the fan module has multiple mounting holes; the snap-fit ​​component 1 has a through hole 101; wherein, multiple connection areas are formed between the backrest spring frame and the fan module, and in each connection area, the spring wires are passed through the through hole 101, that is, the snap-fit ​​component 1 is movably sleeved on the spring wires, and the snap-fit ​​component 1 is snapped into the mounting hole.

[0050] This design utilizes the existing backrest spring frame in the seat back as the mounting attachment for the fan module. The snap-fit ​​1 allows the spring wire to pass through, presenting a form where the snap-fit ​​1 is inextricably hooked onto the spring wire. At the same time, the snap-fit ​​1 also forms a snap-fit ​​with the mounting hole on the fan module, thereby enabling the fan module to be installed into the seat back. The structure has low complexity and the assembly process is easy, making the fan module installation convenient and solving the problem of how to improve the ease of installation of vehicle seat ventilation fans in the prior art.

[0051] Furthermore, the through hole 101 of the snap-fit ​​part 1 has a high capacity for accommodating spring wires. One specification of snap-fit ​​part 1 can be adapted to a variety of spring wires of different diameters. Therefore, snap-fit ​​part 1 can be used on a variety of types of backrest spring frames, with high expandability, and can be applied in seats of a variety of brands and models.

[0052] Figure 1 and Figure 2 The example shown below illustrates a scenario with four connection areas.

[0053] It should be noted that a seat equipped with a fan module can have a continuous front and back backrest to create airflow, or the back of the backrest can be closed, with ventilation channels set in the backrest to guide airflow.

[0054] Generally, common backrest spring frames consist of multiple tension springs or multiple serpentine springs. A tension spring is formed by spirally winding the spring wires, while a serpentine spring is formed by repeatedly bending the spring wires. In this application, it is preferred that the spring wires bend in a reciprocating manner.

[0055] The through hole 101 of the snap-fit ​​component 1 can be designed as a closed hole or a non-closed hole.

[0056] In some alternative embodiments, such as Figure 3 As shown, the snap-fit ​​component 1 is a clip, which includes a first clip 11, a second clip 12, a connecting piece 13, and a resilient snap-fit ​​foot 14. The second clip 12 is disposed opposite to the first clip 11. Both the first clip 11 and the second clip 12 include a flat section 111 and an inclined section 112. The flat sections 111 of the first clip 11 and the flat sections 111 of the second clip 12 are close to each other, while the inclined sections 112 of the first clip 11 and the inclined sections 112 of the second clip 12 gradually move away from each other. The connecting piece 13 connects the inclined section 112 of the first clip 11. The inclined section 112 of the first clip 11 and the inclined section 111 of the second clip 12 are provided on the opposite side of the flat section 111 of the first clip 11 and the flat section 111 of the second clip 12. The elastic snap-fit ​​foot 14 extends from the end of the flat section 111 to the other end and gradually tilts upward. The non-closed hole formed by the inclined section 112 of the first clip 11, the inclined section 112 of the second clip 12 and the connecting piece 13 is the through hole 101. The flat section 111 of the first clip 11 and the flat section 111 of the second clip 12 are snapped into the assembly hole.

[0057] With this configuration, the clip can open and close slightly. During the overall assembly of the seat, even if the backrest spring frame has been assembled and the spring wire has no open end to be inserted, the clip can be smoothly placed around the spring wire by utilizing the notch feature of the through hole 101. Then, the fan module and the clip 1 can be clipped together to complete the installation and fixation of the fan module on the backrest spring frame.

[0058] In some other alternative embodiments, such as Figure 4 As shown, the snap-fit ​​component 1 is a snap fastener, which includes an annular segment 15, a columnar segment 16, and a flexible snap-fit ​​foot 14; the columnar segment 16 is integrally connected with the annular segment 15; the flexible snap-fit ​​foot 14 is disposed on the columnar segment 16, the flexible snap-fit ​​foot 14 is distributed around the columnar segment, and the flexible snap-fit ​​foot 14 extends from one end of the columnar segment 16 to the other end and gradually curves upward; wherein, the closed hole formed in the annular segment 15 is a through hole 101, and the columnar segment 16 is snapped into the assembly hole.

[0059] With this design, the buckle can be placed on the spring wire before it is connected to the backrest body, and the through hole 101 is a closed hole for greater safety and reliability. This also provides a flexible alternative for the design of the snap-fit ​​component 1.

[0060] In some specific embodiments, the fan module includes a fan body 2 and a mounting bracket 3. The fan body 2 is mounted on the mounting bracket 3, and the mounting bracket 3 is provided with mounting holes.

[0061] With this setup, the mounting bracket 3 can be an readily available sheet metal part. Depending on parameters such as the distance between the spring wires of different backrest spring frames, the mounting bracket 3 can be adapted to the design. In this way, the fan does not need to be modified and only one model is required, which helps to control development and production costs.

[0062] In some other specific embodiments, the fan body 2 is connected to the mounting bracket 3 by adhesive nails 4. That is, both the fan body 2 and the mounting bracket 3 have through holes, and the adhesive nails 4 pass through the through holes of both and fix the fan body 2 and the mounting bracket 3 together. The adhesive nails 4 are common connecting accessories in the art, also known as rubber nails 4.

[0063] With this setup, the use of rubber nails 4 for connection allows the high elasticity of the rubber material to effectively absorb vibration and impact, reducing noise and vibration of the fan module during operation.

[0064] Of course, in addition to the above methods, it is also feasible to use ordinary metal screws and nuts to lock and connect the fan body 2 and the mounting bracket 3.

[0065] In some other specific embodiments, the mounting bracket 3 includes a bracket body 31 and an extension 32, the extension 32 extending from the edge of the bracket body 31 in a direction away from the bracket body 31; multiple extensions 32 are provided, and each extension 32 has a mounting hole; the fan body 2 is connected to the bracket body 31. The extending direction of the extension 32 can be vertical, horizontal, or at an inclined angle. Figure 1 and Figure 2 The example shows the cases where the extension direction of the extension 32 is vertical and horizontal.

[0066] With this configuration, the fan body 2 is mounted on the central main part of the mounting bracket 3, while the connecting area is formed on the partial extension 32 of the mounting bracket 3. This arrangement allows for full utilization of all parts of the mounting bracket 3 without any excess, thus optimizing the material cost of the mounting bracket 3. At the same time, the connecting area is far from the fan body 2, which helps the outer trim of the seat back to cover the connecting area, ensuring the aesthetic appeal of the appearance.

[0067] In some other specific embodiments, the multiple spring wires include frame spring wires 5 and intermediate spring wires; the frame spring wires 5 have a span in the vertical direction, and there are two frame spring wires 5 distributed symmetrically about the vertical plane of the seat back; the intermediate spring wires have a span in the horizontal direction and connect between the two frame spring wires 5, and there are at least two intermediate spring wires arranged in the vertical direction; wherein, the fan module is connected between two adjacent intermediate spring wires, that is, the intermediate spring wires are inserted into the snap-fit ​​member 1. Exemplarily, Figure 2 The frame spring wire 5 in the middle is L-shaped;

[0068] It should be noted that the splicing and fixing method between the intermediate spring wire and the frame spring wire 5 can continue to use conventional methods in the existing technology. For example, the intermediate spring wire can be structurally connected to the frame spring wire 5 by overlapping and riveting.

[0069] Further, in some preferred embodiments, the two intermediate spring wires connected to the fan module are a first intermediate spring wire 6 and a second intermediate spring wire 7, with the first intermediate spring wire 6 above the second intermediate spring wire 7; both the first intermediate spring wire 6 and the second intermediate spring wire 7 are reciprocatingly bent, with a portion of the first intermediate spring wire 6 extending horizontally to form a horizontal segment, and a portion of the second intermediate spring wire 7 extending vertically to form a vertical segment; the horizontal segment of the first intermediate spring wire 6 passes through the through hole 101, and the vertical segment of the second intermediate spring wire 7 passes through the through hole 101. Specifically, at least two snap-fit ​​pieces 1 on the upper side of the fan module are in a state where the through hole 101 is horizontally through, and at least two snap-fit ​​pieces 1 on the left and right sides of the fan module are in a state where the through hole 101 is vertically through.

[0070] This design cleverly utilizes the inherent bending direction of the intermediate spring wire to limit the fan module in both the horizontal and vertical directions.

[0071] Based on the aforementioned seat backrest, this application embodiment also provides a seat that includes the aforementioned seat backrest. Since this seat has the aforementioned seat backrest, the beneficial effects brought by the seat backrest are described above and will not be repeated here.

[0072] Based on the aforementioned seat, this application also provides a vehicle that includes the aforementioned seat. Since the vehicle has the aforementioned seat, the beneficial effects brought by the seat are described above and will not be repeated here.
