The seat oscillator drives the seat backrest to vibrate; the seat has the advantages that the seat oscillator with the vibration function is integrated on the seat backrest, the seat backrest is vibrated through the seat oscillator, and the vibrated seat backrest can provide vibration body feeling for passengers.

Description

Technical Field

[0001] The utility model relates to the technical field of vehicle seats, in particular to a backrest structure with a vibration function. Background Art

[0002] With the continuous progress of technology, people's requirements for vehicles are getting higher and higher, and there are more and more functions on vehicle seats. At present, playing music during long-distance driving has become the choice of most people. Listening to music can not only resist fatigue, improve driving safety, but also increase driving pleasure, which is very beneficial. However, all current vehicles only stay at the auditory aspect for the function and effect of driving music, and there is almost no interaction between music and drivers and passengers. Content of the Utility Model

[0003] In view of the above problems, the purpose of the utility model is to provide a backrest structure with a vibration function, which is used to vibrate the seat backrest to overcome the above-mentioned deficiencies of the prior art.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A backrest structure with a vibration function includes: a seat backrest installed on a seat, and the seat backrest is composed of a backrest frame, a backrest support plate, a seat oscillator, a foam assembly and a skin assembly which are arranged in sequence from inside to outside. The bottom of the backrest frame is fixedly connected to the seat frame, the backrest support plate is fixedly connected to the backrest frame, an avoidance hole for installing the seat oscillator is formed on the backrest support plate, the rear seat of the seat oscillator is installed on the back of the backrest support plate, the vibration end of the seat oscillator passes through the avoidance hole and contacts the foam assembly, the foam assembly is fixedly connected to the backrest support plate, the skin assembly wraps the foam assembly and the seat oscillator on the backrest support plate, and the seat oscillator drives the seat backrest to vibrate.

[0006] As a preference of the utility model, the signal wire of the seat oscillator is connected to the vehicle CAN bus, and the power wire of the seat oscillator is connected to the seat power supply.

[0007] As a preference of the utility model, two seat oscillators are symmetrically installed at the middle position of the backrest support plate, and two avoidance holes are formed on the backrest support plate corresponding to the number of seat oscillators.

[0008] The advantages and positive effects of the utility model are: by integrating a seat oscillator with a vibration function on the seat backrest, the seat backrest is vibrated by the seat oscillator, and the vibrating seat backrest can provide a vibration feeling for passengers.

[0015] Refer to Figure 1-2 , this embodiment provides a backrest structure with a vibration function, including: a seat back installed on a seat, the seat back is composed of a backrest frame 1, a backrest support plate 2, a seat oscillator 3, a foam assembly 4, and a skin assembly 5 arranged from inside to outside in sequence. The bottom of the backrest frame 1 is fixedly connected to the seat frame, the backrest support plate 2 is fixedly connected to the backrest frame 1, two avoidance holes 6 for installing two seat oscillators 3 are opened on the backrest support plate 2, the rear seat of the seat oscillator 3 is installed on the back surface (the side away from the passenger) of the backrest support plate 2, the vibration end of the seat oscillator 3 passes through the avoidance hole 6 and contacts the foam assembly 4, the foam assembly 4 is fixedly connected to the backrest support plate 2, the skin assembly 5 covers the foam assembly 4 and the seat oscillator 3 on the backrest support plate 2, and the seat oscillator 3 drives the seat back to vibrate. The signal wire of the seat oscillator 3 is connected to the vehicle CAN bus, and the power wire of the seat oscillator 3 is connected to the seat power supply.

[0016] Working principle: The seat oscillator 3 with the model number 7909160-HZ01 adopts a vibration mode similar to that of a speaker, so it can provide vibrations in multiple directions for the seat back, that is, it can realize the 4D tactile vibration of the seat back.

[0017] The above is only the specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
