Problems solved by technology

[0005] The vibration damping devices involved in these patents are all installed at the bottom of the seat, mainly for the vibration attenuation of the bottom of the seat, and there is no multi-dimensional vibration damping device for damping the vibration of the seat back. It is complex, takes up a lot of space, and is cumbersome to assemble, which limits its application range and cannot be applied to the multi-dimensional vibration attenuation of the backrest of a car seat

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] The car seat back multi-dimensional vibration attenuator includes an outer ring 4 and a mass block 6 located at the center of the outer ring. The mass block and the outer ring are connected by four rubber spokes 5, arranged symmetrically from left to right and up and down. The left part and the right part of the outer ring are provided with mounting plates 3, and bolt holes are arranged on the mounting plates. The mounting plate 3 is connected with the bracket 2 by bolts, and is fixed on the seat back frame 1 through the bracket.

[0017] A mass block is set in the center of the outer ring. Since the mass block and the outer ring are connected by rubber spokes, the mass block can drive the rubber spokes to move locally in the X, Y, and Z directions under external excitation vibration, and the vibration The resulting mechanical energy is converted into elastic p...

Abstract

The invention relates to a multi-dimensional car seat backrest vibration attenuator. The multi-dimensional car seat backrest vibration attenuator comprises an outer lantern ring and a mass block which is arranged in the center of the outer lantern ring, wherein the mass block is connected with the outer lantern ring through a plurality of rubber spokes, both the left part and the right part of the outer lantern ring are respectively provided with an installation plate, and each installation plate is provided with a bolt hole. By adopting the multi-dimensional car seat backrest vibration attenuator, the multi-dimensional vibration attenuation can be performed for a car seat backrest, and the sitting comfort of a seat can be improved.

Description

technical field [0001] The invention relates to an accessory device of an automobile body, in particular to a multi-dimensional vibration attenuator for an automobile seat back. Background technique [0002] The car seat often produces strong vibration during driving. The dynamic comfort of the car seat refers to the comfort experienced by the seat after the vibration is transmitted to the human body through the seat frame and seat cushion under the driving state. It is mainly related to the vibration characteristics. related. In order to make the seat have good vibration comfort, passive vibration isolation is generally used at home and abroad to attenuate the harmful vibration of the seat. Because the passive control vibration damping effect is generally not ideal, the driver is susceptible to various types of vibration shocks, which greatly reduces the ride comfort. comfort rate. Therefore, researchers have designed various damping devices to attenuate seat vibration an...
