Description

Technical Field

[0001] This application relates to the technical field of automotive parts, and particularly to a seat mounting structure for an exciter. Background Art

[0002] With the development of technology, more and more vibration seats have emerged on the market to improve people's life experience, such as low-frequency vibration seats for enhancing audio-visual experience, vibration massage chairs for relieving the physical fatigue of users, and vibration reminder seats in cars to remind drivers of certain matters. Traditional exciters are installed on the seat back spring or the support plate of the lumbar support. However, this installation method has some problems. Firstly, some seats are not equipped with a lumbar support. Secondly, as the functions of seats are increasing, there may be other functional components between the back spring and the seat foam, such as ventilation bags, which will cause the exciter to be installed only in a relatively remote corner. Thirdly, vibration will dissipate through the back spring, affecting the vibration effect.

[0003] In view of the problems faced in the above situation, the inventor of the present application has designed a seat mounting structure for an exciter to facilitate the installation of the exciter at any position on the seat foam and enhance the vibration experience of users.

[0024] Compared with the prior art, the beneficial effects of the present application:

[0025] This application provides a seat mounting structure for a vibrator, including:

[0026] A foam body;

[0029] In existing vibrating seats, the vibrator and the foam body are respectively fixed to the base bracket of the seat. Under the overall limitation of the base bracket of the seat, the vibrator is fixed to a preset position so that the vibrator performs vibration operations in a predetermined area of the foam body. The seat mounting structure of the vibrator provided by this application directly connects the vibrator to the foam body by using the mounting member.

[0049] In order to enable those skilled in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present application. Specifically, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0055] In the existing vibrating seat, the vibrator 1 and the foam body are respectively fixed to the seat base bracket. Under the overall limitation of the seat base bracket, the vibrator 1 is fixed to a preset position so that the vibrator 1 performs a vibration operation in a predetermined area of the foam body. The seat mounting structure of the vibrator provided in this application directly connects the vibrator 1 to the foam body by using a mounting member.

[0057] On the other hand, during the operation of the vibrator 1, part of the vibration energy is also generated in the housing of the vibrator 1. In the traditional vibrating seat, the vibration energy generated by the housing of the vibrator 1 will dissipate through connecting members such as back springs connected to the vibrator 1; while in the technical solution provided in this application, the vibration energy generated by the housing of the vibrator 1 will be conducted to the foam body through the mounting bracket 6 to enhance the vibration intensity of the vibrator 1 and further improve the vibration feeling of the seat.

A part of the mounting member is exposed in the second groove. A clamping groove is arranged at a position corresponding to the exposed section of the mounting member on the outer shell of the vibrator 1. After the vibrator 1 is placed in the first groove, the vibrator 1 is clamped to the mounting bracket 6 through the clamping groove.

[0065] In a preferred embodiment, the mounting member includes a bead ring, and the range defined by the bead ring covers at least the cross-section of the vibrator of one vibrator 1. One or more vibrators 1 can be arranged in one bead ring.

[0066] In a preferred embodiment, the mounting member is connected to the inner surface of the foam. The mounting member uses the above-mentioned bead ring. The mounting member further includes a connecting claw 61. The connecting claw 61 is inserted into the foam from the inner side of the foam and adhesively connected to the foam. A buckle is arranged at the end of the connecting claw 61 exposed outside, and the bead ring is clamped to the connecting claw 61 through the buckle.

[0067] Optionally, a clamping groove is arranged on the outer shell of the vibrator 1, and the vibrator 1 is clamped to the bead ring through the clamping groove.

[0068] Optionally, a mounting plate 7 is fixedly arranged on the bead ring, and a through hole is formed on the mounting plate 7. The through hole is the opening area of the mounting member; the vibrator 1 is fixedly connected to the mounting plate 7 through bolts.

[0072] The main body foam body 3, which is the foam body located in the peripheral area of the vibrator 1; (in this application, the vibrator 1 vibrates in the direction perpendicular to the extension plane of the seat back 8 / cushion 9, and "the peripheral area of the vibrator 1" specifically refers to the area around the periphery of the vibrator 1 in the extension direction of the seat back 8 / cushion 9 extension plane)

[0074] In this application, the top foam body 2 and the main body foam body 3 are arranged at intervals and are connected by the connecting body 4; when the top foam body 2 vibrates, kinetic energy is transmitted to the main body foam body 3 through the connecting body 4. The connecting body 4 is used to reduce the cross-sectional area of the connection path between the top foam body 2 and the main body foam body 3 (in the existing product, the top foam body 2 and the main body foam body 3 are integrally formed, and the cross-section of the connection path between the top foam body 2 and the main body foam body 3 is the circumferential side surface of the top foam body 2; in the design direction of this application, the cross-section of the connection path between the top foam body 2 and the main body foam body 3 is the cross-section of the connecting body 4), reduce the kinetic energy transmission efficiency between the top foam body 2 and the main body foam body 3, reduce the circumferential dissipation of the kinetic energy generated by the vibrator 1 to the main body foam body 3, and retain more kinetic energy in the top foam body 2 and transmit it to the seat surface. Without changing the performance of the vibrator 1 and with the same power consumption, a stronger vibration experience is provided for the user.

[0077] In a preferred embodiment, in the vibration direction of the vibrator, the thickness of the top foam body 2 is less than that of the main body foam body 3. This reduces the absorption of vibration energy between the top foam body 2 and the exciter 1.

[0078] In a preferred embodiment, a conduction block 5 is provided inside the top foam body 2; the hardness of the conduction block 5 is greater than that of the top foam body 2, and the kinetic energy transfer efficiency of the conduction block 5 is greater than that of the top foam body 2.
