Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive seats, specifically relating to a backrest suspension structure with a rhythmic function. Background Technology
[0002] To improve seat comfort, reduce fatigue, and provide a more comfortable and dynamic experience for drivers and passengers, a rhythmic function is often added to the seat. For example, Chinese Patent 2023223428189 discloses a seat back structure with a rhythmic function. This seat back structure, as shown... Figure 1 As shown, the structure includes a backrest support plate 2 and a vibrator 3. The backrest support plate 2 is mounted on the seat frame assembly 1, and two interfaces 21 are provided at the upper end of the backrest support plate 2. The vibrator 3 passes through the interfaces 21 and is fixed to the backrest support plate 2 by screws. However, the backrest support plate 2 used in this structure is relatively hard and lacks elasticity, which will affect the comfort of the vibrator 3 when vibrating. In some gentle rhythm modes, it may feel stiff. It is also less adaptable to different body shapes and sitting postures of different passengers. At the same time, it is more expensive and has lower versatility. Utility Model Content
[0003] The purpose of this utility model is to solve the above-mentioned problems by providing a backrest suspension structure with a rhythmic function. This backrest suspension structure uses a backrest suspension to support the human back. By installing a rhythmic device on a fixed plate above the backrest suspension, the rhythmic function of the seat is increased. Since the backrest suspension itself is elastic and adjustable, when combined with the rhythmic device, it can better adapt to different sitting postures and body pressures. While providing a rhythmic experience, it can also ensure a comfortable backrest angle, save costs, and has greater versatility.
[0004] To achieve the above objectives, this utility model provides a backrest suspension structure with a rhythmic function, including a backrest suspension, a fixing plate, and a rhythmic device. The backrest suspension is installed on the seat frame assembly, and a fixing plate is provided above the backrest suspension. The fixing plate is provided with a rhythmic device that can generate rhythmic vibration.
[0005] As a further optimization, the fixing plate is made of plastic, with its left and right ends embedded in the vertical steel wires on the left and right sides of the backrest suspension, and its lower end embedded in the horizontal steel wire at the upper end of the backrest suspension.
[0006] As a further optimization, the fixing plate has mounting holes for mounting a rhythm device, which is fixed in the mounting holes of the fixing plate by a bolt and nut connection.
[0007] Advantages and beneficial effects of this utility model
[0008] 1. This utility model has a fixing plate embedded in the top of the backrest suspension. The fixing plate is provided with mounting holes for installing the rhythm device. The rhythm device passes through the mounting holes and is fixed to the fixing plate by screws. Since the backrest suspension itself is elastic and adjustable, when combined with the rhythm device, it can better adapt to different sitting postures and body pressures, providing a rhythmic experience while ensuring a comfortable backrest angle.
[0009] 2. The rhythmic device in this utility model is not directly installed on the backrest suspension, but is installed above the backrest suspension through a fixing plate. Therefore, it avoids affecting the accuracy of the vibration transmission of the rhythmic device by directly installing the rhythmic device on the backrest suspension, thus improving the rhythmic effect. At the same time, it also avoids the relative displacement between the rhythmic device and the backrest suspension when the rhythmic device vibrates greatly.
[0010] 3. The rhythm device in this utility model is installed in the mounting hole of the fixed plate by means of bolts and nuts, which can make the rhythm device more secure during use, less prone to shaking and loosening, and ensure safety during use. At the same time, compared with the backrest support plate, the backrest suspension of this utility model is lower in cost and more versatile. Attached Figure Description
[0011] To more clearly illustrate the technical solutions in the embodiments of this utility model, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0014] Reference numerals in existing patents: Seat frame assembly 1, backrest support plate 2, interface 21 and vibrator 3. This application Figure label: Backrest suspension 1, vertical steel wire 11, horizontal steel wire 12, fixing plate 2, mounting hole 21, vibrator 3, seat frame assembly 4 and fan 5. Detailed Implementation
[0015] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0016] like Figure 1 The aforementioned backrest suspension structure with rhythmic function includes a backrest suspension 1, a fixing plate 2, and a rhythmic device 3. The backrest suspension 1 is suspended below the seat frame assembly 4 to support the human backrest and provide a more comfortable seating experience. A plastic fixing plate 2 is embedded above the backrest suspension 1. The left and right ends of the fixing plate 2 are embedded in the vertical steel wires 11 on the left and right sides of the backrest suspension 1, and the lower end of the fixing plate 2 is embedded in the horizontal steel wire 12 at the upper end of the backrest suspension 1. The fixing plate 2 can provide more precise positioning for the rhythmic device 3, ensuring the operation of the rhythmic device 3. In terms of performance and effect, the fixing plate 3 can also be used as an extension mounting plate for installing other functional components on the seat, such as audio equipment, fan 5, etc. The upper side of the fixing plate 2 has two mounting holes 21. The rhythmic device 3 is installed on the mounting holes 21 of the fixing plate 2 by the cooperation of bolts and nuts. The bolt and nut connection method can make the rhythmic device 3 more secure during use, and it is not easy to shake or loosen, ensuring the safety of the rhythmic device 3. At the same time, the installation of the rhythmic device 3 by the fixing plate 2 made of plastic material can ensure the accuracy of the vibration transmission of the rhythmic device 3 and improve the rhythmic effect.
[0017] Because the backrest suspension 1 itself is elastic and adjustable, the present invention provides greater comfort when combined with the vibrator 3 compared to the combination of the backrest support plate and the vibrator. It is also more adaptable to different body shapes and sitting postures of different passengers, and can better adapt to different sitting postures and body pressures. While providing a rhythmic experience, it can also ensure a comfortable backrest angle for drivers and passengers.
[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the present utility model.
