Description

Damper for non-adhesive vehicle seat {nonadhesive type vehicle seat damper}

The present invention relates to a damper for a vehicle seat that is installed inside the seat of a vehicle to damp vibrations generated from the lower part of the vehicle and transmitted to the occupant, and more specifically, a mass member and a bracket are combined with a rubber supporter, It is improved so that the supporter passes through the bracket and wraps around both sides of the bracket rather than by adhesion.

As is well known, in driving a vehicle, vibration occurs due to numerous factors such as contact between the road surface and the tire, and the driving of the engine.

The resulting vibration is transmitted to the driver and passengers in the vehicle, causing them to feel uncomfortable and tired, and by generating noise, they feel physically exhausted and mentally fatigued, thereby reducing the riding comfort.

In order to attenuate or suppress such vibrations, products installed in various places of the vehicle have been developed and made, and a related technology for a seat damper that is installed on a vehicle seat and attenuates vibration transmitted to a occupant is known.

However, the conventional damper for a vehicle seat has a large overall volume because a mass member for absorbing vibration, a rubber supporter, and a bracket for fixing are integrally formed. There is a problem in that productivity is low due to inconvenience.

In order to improve the above problems, the mass member and the bracket were manufactured as separate units, an adhesive was applied between them, and the supporter was molded and attached at the same time by vulcanization to improve the efficiency and productivity of the work.

However, in the supporter that is located between the bracket and the mass member and transmits the vibration transmitted from the bracket to the mass member, the area in contact with the bracket is small, so the entire transmitted vibration cannot be completely absorbed, so the unabsorbed vibration is again The vibration damping effect is reduced as it spreads to the surroundings.

In addition, if both the mass member and the bracket are integrated with the supporter by adhesive, the process such as shot blasting to roughen both the bonding surface of the mass member and the bonding surface of the bracket, forming a phosphate film, and applying an adhesive is required. In addition, the adhesive function applied to bind the bracket and the supporter deteriorates over time and loses adhesive force due to continuous vibration, and the supporter is separated and the damper lifespan prematurely. There is a problem with doing it.

The present invention, devised to solve the above problems, provides a damper for a vehicle seat with improved bonding between the bracket and the supporter, so that the bond between the bracket and the supporter is strong, thereby increasing the life of the damper and absorbing the vibration transmitted to the bracket. It is easy to improve the vibration damping effect, and the purpose is to shorten the production process.

The damper for a vehicle seat of the present invention for achieving the above object includes a bracket that is directly installed on a vehicle seat to receive vibration, a mass member for damping vibration, and a supporter positioned between the bracket and the mass member to integrate each unit After forming a hole in the bracket through which the supporter can pass, when the supporter is molded, the material of the rubber support passes through the hole and wraps the bracket from the opposite side to effectively support the bracket and support the bracket. It is characterized in that it rapidly absorbs the vibration transmitted to the body and transmits it to the mass member.

The non-adhesive vehicle seat damper of the present invention provides a damper with excellent bonding by insert-molding the supporter into the bracket. It is easy to transmit and the vibration damping effect is improved, and there is an effect of omitting the conventional shot blasting process, phosphate coating process, and adhesive application, which must be applied to the bracket.

Hereinafter, the damper for a non-adhesive vehicle seat of the present invention will be described in detail. These descriptions are based on an embodiment for implementing the present invention, and the technical idea pursued by the present invention is described in this document. It is not intended to be limited to the form described in, and it should be understood to include various modifications, equivalents and/or alternatives of the embodiments of the present invention.

In addition, although the effects according to the configuration of the present invention are not explicitly described and described while describing the embodiments of the present invention, it is natural that the effects predictable by the configuration should also be recognized.

The damper (1) of the present invention is composed of a bracket (10) fixed directly to the vehicle seat, a supporter (20) that is inserted and bound to the bracket (10), and a mass member (30) that is attached to the supporter (20), In particular, the supporter 20 and the support portion 10-1 of the bracket 10 exclude adhesion to each other, and a part of the supporter 20, that is, the inner adhesion part 20-2 and the outer surface adhesion part 20-3 It is characterized in that the bracket 10 is integrated in the form of surrounding the inner and outer surfaces of the support portion (10-1).

Looking at the bracket 10 first, the upper both sides have assembly holes 12 so as to be assembled to the vehicle seat as an assembly support part 13, and the assembly part 11 bent to face inwardly and the mass member 30 are supported. A support portion 10 - 1 is formed for this purpose, and a connection portion 15 connecting the support portion 10 - 1 is configured to support the mass member 30 by the supporter 20 .

In particular, the main through hole 14 is formed at a position corresponding to the center line of the mass member 30 in the supporting part 10-1 of the lower part of the assembly unit 11, and the main through hole 14 is divided at an even angle around the main through hole 14. Three or more auxiliary through-holes 14-1 were formed.

The mass member 30 has a shape that can be located in the inner center of the bracket 10, and the adhesive is applied to the application surfaces 31 on both sides at a constant thickness so that the member joint portion 20-1 of the supporter 20 is adhered. do.

Looking at the configuration in which the support part 10-1 and the mass member 30 are integrated using the supporter 20, the supporter 20 has a member joint part 20-1 having a larger diameter than the elastic part 21 on one side. ), using an adhesive, so that the member joining portion 20 - 1 is integrated with the side cross-section of the mass member 30 .

And, in integrating the supporter 20 with the support part 10-1 of the bracket 10, the diameter of the supporter 20 is expanded than the elastic part 21 when molding the supporter 20 and is in close contact with the inner surface of the support part 10-1. At the same time as forming the inner adhesion part 20-2, an outer surface adhesion part 20-3 which is in close contact with the outer surface of the support part 10-1 was formed, and a rubber material was made of the main through hole 14 and the auxiliary through hole 14. -1) while passing through, the inner contact portion 20-2 and the outer surface contact portion 20-3 are integrated with each other and the main connection portion 20-4 surrounds the support portion 10-1 in an elastic state. and forming the auxiliary connection part 20-5 to be formed.

As a result, the supporter 20 serves as a link between the bracket 10 and the mass member 30 composed of a single piece, and integrates the single piece of structure to improve bonding strength and safety.

When the integrated damper 1 is installed on the vehicle seat, the assembly hole 12 of the assembly part 11 is aligned with the vehicle seat and the assembly support part 13 is fastened to fix it.

The operation of the present invention configured as described above is as follows.

The vibration generated in the vehicle is transmitted to the vehicle seat, and the vibration transmitted to the vehicle seat is damped by the damper 1 .

More specifically, the vibration transmitted through the vehicle seat is transmitted to the bracket 10 , and is transmitted from the bracket 10 to the mass member 30 .

In addition, as the area in contact with the bracket 10 is large, the mass member 30 reacts quickly to damp the vibration by rapidly reacting to the vibration transmitted to the bracket 10 and transmitting the vibration to the mass member 30 .

The mass member 30 receiving the vibration vibrates together with the supporter 20 , and the supporter 20 adjusts the natural frequency and phase angle generated by the mass member 30 to attenuate unpleasant vibrations transmitted to the occupant.

In particular, in the vibration damping process as described above, according to the present invention, the inner and outer contact portions 20-2 and 20-3 of the supporter 20 are attached to the inner and outer surfaces of the supporter 10-1 of the bracket 10 according to the present invention. It is in close contact with the enclosing form, and while the main connection part 20-4 and the auxiliary connection part 20-5 are connected to the main through hole 14 and the auxiliary through hole 14-1, the inner contact part 20-2 and Since it plays a role of pulling the outer surface adhesion part 20-3 to strongly adhere it, effectively distributing the force such as vibration and torsion received by the elastic part 21 of the supporter 20 while effectively integrating the vibration and damping the vibration. will be.

In addition, since the main connection part 20-4 passing through the main through hole 14 is formed, and the auxiliary connection part 20-5 passing through the auxiliary through hole 14-1 is formed in a position close to the periphery, the inner contact part is formed. The auxiliary connection part 20-5 disperses the force or elasticity acting laterally on the main connection part 20-4 while strengthening the adhesive force and adhesion to the edge of the 20-2 and the outer surface adhesion part 20-3. It serves to protect the main connection part 20 - 4 from stress or repeated force, and maximizes the vibration damping effect while extending the life of the supporter 20 as a whole.

In this way, the supporter 20 is in contact with the bracket 10 over a large area and forms the main connection part 20-4 and the auxiliary connection part 20-5 penetrating the support part 10-1, so it is delivered to the bracket 10. It is possible to quickly absorb the incoming vibration and transmit it to the mass member 30 to be attenuated.

In addition, the supporter 20 is not attached to the bracket 10 with an adhesive, but is integrated by a method such as insert injection, so that the bonding force is formed firmly, so that the adhesive force is weakened over time or there is no worry about falling due to vibration. 1) has the advantage of high lifespan.
