Description

Technical Field

[0001] This utility model relates to the field of automotive seats, and in particular to seat structures. Background Technology

[0002] To improve seat comfort, the existing seats are equipped with massage and ventilation systems.

[0003] Existing conventional massage valve bodies are usually arranged on the backrest spring frame, and the frame usually needs to be welded to the bracket for mounting the backrest spring frame and felt plate assembly. The parts are complex in structure, heavy in weight, expensive in cost, and have long assembly time.

[0004] The technical problem to be solved by this application is: to reduce weight and save costs while improving the C-NCAP whiplash performance of the seat, reducing the difficulty of installing the massage components inside the seat, and improving the comfort of the seat. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a seat back structure.

[0006] The technical solution adopted by this utility model is as follows: a seat back structure, including a metal back plate, a support block and a massage component. The support block is fixedly disposed between the massage component and the metal back plate. The support block is provided with a sound insulation baffle. The sound insulation baffle surrounds and forms a sound insulation zone. The massage component is disposed in the sound insulation zone.

[0007] In some embodiments, the massage assembly includes a massage valve body and a massage air pump, and the sound insulation zone includes a sound insulation zone one and a sound insulation zone two, which are not connected to each other. The massage valve body is located in the sound insulation zone one, and the massage air pump is located in the sound insulation zone two.

[0008] In some embodiments, the massage valve body is provided with connecting pins that pass through the support block, and the massage valve body is fixedly connected to the metal back plate by the connecting pins.

[0009] In some embodiments, the massage air pump is provided with a connecting clip, through which the massage air pump is fixedly connected to the metal back plate.

[0010] In some embodiments, a ventilation fan is included, which is fixedly mounted on the backrest air bag, which is fixed to the back of the backrest foam.

[0011] In some implementations, the soundproof zone includes three soundproof zones, with ventilation fans located in the three soundproof zones.

[0012] The beneficial effects of this utility model are as follows: This type of seat backrest structure increases the backrest torso angle by setting support blocks, thereby improving backrest comfort. At the same time, it reduces the noise of the massage valve and massage air pump, prevents the fan from hitting the metal back panel, has a simple structure, is easy to assemble, and can further reduce the probability of abnormal noise. It increases the backrest indentation and increases the backrest torso angle, thereby improving whiplash score and backrest comfort. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0016] Please see Figure 1 This utility model provides a technical solution: a seat back structure, including a backrest foam body 6, a metal back panel 1, a support block 2, a massage component 3, and a ventilation fan 4. The support block 2, the massage component 3, and the ventilation fan 4 are disposed between the backrest foam body 6 and the metal back panel 1. The ventilation fan 4 has a communicating backrest air bag 5, which is fixedly connected to the ventilation fan 4 and fixed to the back of the backrest foam 6.

[0017] The support block 2 is fixedly mounted on the metal back plate 1, and is fixedly positioned between the massage component 3 and the metal back plate 1. The support block 2 is equipped with a sound insulation baffle, which surrounds the massage component 3 to form a sound insulation zone. The massage component 3 is positioned within the sound insulation zone to reduce the transmission of noise from the massage component 3 and effectively reduce noise.

[0018] Support block 2 is made of polyurethane foam.

[0019] The massage component 3 includes a massage valve body 31 and a massage air pump 32. The sound insulation zone includes a first sound insulation zone 21 and a second sound insulation zone 22, which are not interconnected. The massage valve body 31 is located in the first sound insulation zone 21, and the massage air pump 32 is located in the second sound insulation zone 22. The massage valve body 31 has connecting nails that pass through the support block 2. The massage valve body 31 is fixedly connected to the metal back plate 1 via connecting nails 33. The connecting nails 33 can buffer the collision between the massage valve body 31 and the metal back plate 1 during vibration, thus preventing noise. The massage air pump 32 has connecting clips 34, and the massage air pump 32 is fixedly connected to the metal back plate 1 via connecting clips 34.

[0020] The ventilation fan 4 is fixedly mounted on the backrest air bag 5. The sound insulation zone also includes a third sound insulation zone 23. The first sound insulation zone 21, the second sound insulation zone 22 and the third sound insulation zone 23 are not connected to each other, and the ventilation fan 4 is located in the third sound insulation zone 23.

[0021] The working principle and usage of this utility model are as follows: The support block 2 provides support for the middle part of the metal backrest and ensures the backrest's indentation. The massage valve body 31, massage air pump 32, and ventilation fan 4 are respectively built into different areas of the support block 2. When the massage valve body 31, massage air pump 32, and ventilation fan 4 are working, the noise generated is better contained by the ventilation support block 2, reducing noise emission.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
