In one example of the present invention, the flexible loop portion 110 is removably connected to the rigid loop portion 120; the flexible ring portion 110 is detachably coupled to the rigid ring portion 120, thereby simplifying the manufacturing process of the cushion 100, and since the two are independent of each other, it is easy to replace one of them when it is worn and damaged, and the use cost is saved.
In one example of the present invention, the,
a protrusion 122 protruding in a direction away from the central axis a is formed on the outer contour surface 120S of the rigid ring portion 120;
the inner contour surface 110S of the flexible ring portion 110 is formed with a groove 112 extending in a direction away from the central axis A thereof;
the protrusion 122 is matched with the groove 112;
that is, the rigid collar portion 120 is mounted within the flexible collar portion 110 by engagement of the projections 122 within the recesses 112, which is a simple and convenient arrangement;
of course, the present invention is not limited thereto, and the rigid ring portion 120 and the flexible ring portion 110 may be connected by the following structure:
a groove 112 extending in a direction close to the central axis a is formed in the outer contour surface 120S of the rigid ring portion 120;
a protrusion 122 protruding toward a direction close to a central axis a is formed on an inner contour surface 110S of the flexible ring portion 110;
the protrusion 122 fits into the groove 112.
In one example of the present invention, the,
the protrusions 122 are provided in plurality and spaced apart along the circumferential direction of the rigid ring portion 120;
the grooves 112 are provided at intervals along the circumferential direction of the flexible ring portion 110;
the plurality of protrusions 122 correspond to the plurality of grooves 112 one by one;
by providing a plurality of protrusions 122 and grooves 112 that correspond to the plurality of protrusions 122, the coupling between the rigid collar portion 120 and the flexible collar portion 110 may be more reliable and less susceptible to loosening.
In an example of the present invention, the width of the protrusion 122 in the circumferential direction is gradually decreased from one end close to the rigid ring portion 120 to one end far from the rigid ring portion 120; that is to say, the protrusion 122 and the rigid ring portion 120 are integrally formed, and the specific structure is similar to the structure of the gear teeth, and since the stress is greatest at the joint of the protrusion 122 and the rigid ring portion 120 and is gradually reduced toward the end far away from the joint, the stress requirement of the protrusion 122 is met, and the integral structure of the rigid ring portion 120 is more reliable.
In an example of the present invention, the junction of the protrusion 122 and the rigid ring part 120 is further configured with a chamfer, and the stress concentration phenomenon can be greatly reduced by providing a chamfer at the junction of the protrusion 122 and the rigid ring part 120, thereby improving the fatigue life of the rigid ring part 120.
In one example of the present invention, the dimension of the rigid collar portion 120 in the thickness direction is smaller than the dimension of the flexible collar portion 110 in the thickness direction; this is because the flexible loop portion 110 is easily deformed when a force is applied in the thickness direction, and the dimension of the rigid loop portion 120 in the thickness direction is made smaller than the dimension of the flexible loop portion 110 in the thickness direction, so that a rigid connection can be avoided, and both end faces in contact with the flexible loop portion 110 in the thickness direction are still in a flexible connection state; preferably, the dimension of the rigid collar portion 120 in the thickness direction is 1/2 of the dimension of the flexible collar portion 110 in the thickness direction.
In an example of the present invention, the rigid ring portion 120 is symmetrically disposed in the first mounting hole 111 in the thickness direction, that is, the groove 112 on the contour surface 110S in the flexible ring portion 110 is symmetrically disposed in the first mounting hole 111 in the thickness direction, and the protrusion 122 of the rigid ring portion 120 is engaged in the groove 112, so that the shock pad 100 is stressed optimally, the fatigue life is strongest, and the overall structure is more reliable.
In one example of the present invention, the flexible loop portion 110 and the rigid loop portion 120 are injection molded as a single piece.
Specifically, the flexible ring portion 110 and the rigid ring portion 120 may be formed by means of distributed injection molding, i.e., a first mold is used to injection mold the rigid ring portion 120, and the rigid ring portion 120 is placed in a second mold after being cooled to perform injection molding on the flexible ring portion 110.
The advantage of the distributed injection molding is that the tight joint connection between the flexible ring part 110 and the rigid ring part 120 is realized by a simple method, and the problem that the rigid ring part 120 and the flexible ring part 110 are easy to separate and fall off is solved, but once one of the rigid ring part 120 or the flexible ring part 110 is damaged, the mode cannot be replaced, and the use cost is increased.
In one example of the present invention, the flexible ring portion 110 is a rubber member, and the rigid ring portion 120 is a plastic member.
In short, the rubber part has a good damping effect, and the plastic part has a strong wear resistance, such as a nylon part, which can satisfy the use environment of the damping pad 100 and has a low cost.
The above description is only an exemplary embodiment of the present invention, and is not intended to limit the scope of the present invention, which is defined by the appended claims.
Those skilled in the art will appreciate that various features of the various embodiments of the invention described hereinabove may be omitted, added to, or combined in any manner accordingly.
