Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 4, the spring seat for the swing arm of the automobile comprises a body, wherein a first butt joint part butted with the spring and a second butt joint part butted with the swing arm are formed on the body, the body comprises a first body 100 and a second body 200 connected with the first body 100 and supporting the first body 100, the first body 100 is made of rubber, the second body 200 is made of plastic, the first butt joint part is formed on one side of the first body 100, which is far away from the second body 200, and the second butt joint part is formed on one side of the second body 200, which is far away from the first body 100.

Specifically, the rubber of the first body 100 is high-resilience rubber. The plastic of the second body 200 is high-strength fiberglass plastic.

A side of the first body 100 remote from the second body 200 extends in a spiral shape. This side heliciform extends and is more convenient for and realize the high stability after the butt joint with the spring, is formed with the semiannular holding tank that holds first body 100 on the second body 200 (semiannular holding tank is also following this side and personally presenting the heliciform and extending), and first body 100 locates in the holding tank. The second body 200 provides support for the first body 100, acting as a skeleton of spring seats, ensuring the deformation movement of the rubber within the skeleton.

In this example, after the second body 200 is injection molded, the first body 100 is vulcanization molded on the second body 200, the first body 100 is vulcanization molded with the hook 101 abutting against the second body 200, the second body 200 is provided with the engaging hole for engaging with the hook 101, as shown in fig. 4, the number of the hook 101 and the engaging hole is three, the first body 100 and the second body 200 are stably connected by the engaging and engaging of the hook 101 and the engaging hole formed by vulcanization, thereby preventing the two from falling off during transportation, and omitting the assembly process of the first body 100 and the second body 200.

Further, when spring and spring holder butt joint installation, spring and first butt joint portion adhesive connection are specifically as follows: the first butt joint portion comprises an arc-shaped groove 10 formed in one side face, away from the second body 200, of the first body 100 and used for containing the end portion of the spring, and a plurality of glue grooves 11 formed in the wall of the arc-shaped groove 10, wherein the arc-shaped groove 10 extends along the extending direction of the first body 100, and the glue grooves 11 are sequentially distributed at intervals along the extending direction of the arc-shaped groove 10. When spring and spring holder butt joint installation, the spring tip is located arc wall 10, and the coating has activator, cold glue or gluing agent in 10 cell walls of arc wall and glue groove 11, lets the spring more firm with being connected of spring holder through gluing.

In addition, the glue groove 11 sets a thickness standard for a subsequent gluing process, so that glue can be uniformly distributed when the glue is glued, the gluing is more convenient, the mass production and the control are convenient, and the adhesive property of the glue is stronger.

In this example, the spring seat further includes two sets of fastening structures for fastening the spring, which are disposed on a side surface of the first body 100 away from the second body 200, and the fastening structures include a first fastening member 103 and a second fastening member 104 disposed on two sides. The first buckling piece 103 and the second buckling piece 104 are rubber parts vulcanized and formed with the first body 100, and rubber buckling pieces are added, so that the holding force is increased when the first body 100 is combined with a spring, and the matching is more stable; the buckle structure further improves the firm strength of connection between spring and the spring holder.

Further, a dust blocking member 102 is provided at one end of the first body 100 at the arc-shaped groove 10. The dust blocking member 102 is also a rubber member vulcanized and molded together with the first body 100, and after the spring and the spring seat are butt-jointed and mounted, the side edge of the dust blocking member 102 is in abutting seal with the spring, so that external dust and dirt are prevented from entering the arc-shaped groove 10.

Further, the second docking portion includes a serrated fixing pin 201 and a positioning pin 202 provided on a side of the second body 200 remote from the first body 100. The locating pin 202 is used for being connected with the swing arm location, adopts cockscomb structure fixed pin 201, can adapt to different thickness swing arm metal discs, and the sawtooth of reverse setting can also reduce the spring holder to a certain extent and deviate from the risk from the swing arm.

Furthermore, a plurality of hollowed-out holes 203 are formed on a side of the second body 200 away from the first body 100, and the hollowed-out holes 203 are distributed in a honeycomb shape. Most of the second body 200 uses the honeycomb-shaped hollow holes 203, and the honeycomb-shaped hollow holes 203 are of an optimal topological structure covering a two-dimensional plane, so that the weight reduction effect is obvious, and the geometric strength performance is excellent.

To sum up, the utility model discloses a spring holder for automobile swing arm, its rubber of first body adopt high resilience rubber, and the plastics of the second body adopt the fine plastics of high strength glass to satisfy and use under the strong prerequisite in life-span, greatly reduced the whole weight of product, have high strength lightweight characteristic to save electroplating anticorrosion technology, reduced the adverse effect to the environment, more environmental protection.

Using a second body (skeleton) of plastic, changing the elastic modulus gradient of the spring system, from the original elastic modulus gradient of the material, swing arm/vehicle body (metal) → metal spring seat skeleton (metal) → rubber support → cold glue (glue) → spring; the optimization is swing arm/automobile body (metal) → plastics spring holder skeleton (plastics) → rubber supports → cold glue (glue) → spring, and elasticity modulus gradient is more even, has just greatly reduced the endurance strength problem that the stress distribution inequality leads to on the material selection cooperation, arranges and the weight management and control the condition in limited chassis, has improved the durability of spring holder and spring system.

The present invention has been described in detail, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the same, and the protection scope of the present invention should not be limited thereby, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
