The invention discloses a connecting mechanism for connecting a vacuum pump and a shock absorber, which comprises a cup-shaped supporting plate, wherein the cup-shaped supporting plate is a triangular plate, three corners of the triangular plate are respectively provided with a threaded mounting hole, one corner of the triangular plate is provided with a limiting shock absorber cavity, the threaded mounting hole is positioned in the limiting shock absorber cavity, the middle of the triangular plate is provided with a main shock absorber cavity, and the main shock absorber cavity is provided with a threaded mounting hole. The invention has the beneficial effects that: can prevent that the bumper shock absorber excessively warp and arouse the damage, play safe and reliable's protection bumper shock absorber again, make the bumper shock absorber fully and keep its good shock attenuation effect for a long time, make the difficult emergence of bumper shock absorber drop moreover.
Description
Technical Field
The invention belongs to the technical field of appliances, and particularly relates to a connecting mechanism for connecting a vacuum pump and a shock absorber.
Background
New energy automobile is more and more regarded as important, but because the inside reciprocating motion that is of electric vacuum pump can cause the unbalanced force of radial direction to can arouse vibrations. And the electric vacuum pump falls off under the working condition of severe inertia impact during the running of the whole vehicle. Based on the continuous improvement of NVH performance requirement of the existing new energy automobile on the whole automobile, and the consideration of the reliability and the safety of the whole automobile. A damping structure of an electric vacuum pump suitable for reciprocating motion is specially developed. The prior vacuum pump has the defects on the connection structure with the damping mechanism: firstly, the damping mechanism is instable to install and is easy to fall off from the vacuum pump; secondly, the damping mechanism has no protection measure, and is damaged by continuous impact force in continuous vibration impact.
Disclosure of Invention
The invention aims to solve the technical problems and provide a connecting mechanism for connecting a vacuum pump and a shock absorber, which can prevent the shock absorber from being damaged due to excessive deformation, can safely and reliably protect the shock absorber, can ensure that the shock absorber fully and permanently keeps good shock absorption effect, and can ensure that the shock absorber is not easy to fall off, and the technical scheme is as follows:
the connecting mechanism is characterized by comprising a cup-shaped support plate, wherein the cup-shaped support plate is a triangular plate, threaded mounting holes are formed in three corners of the triangular plate respectively, a limiting shock absorber cavity is formed in one corner of the triangular plate, the threaded mounting holes are located in the limiting shock absorber cavity, a main shock absorber cavity is arranged in the middle of the triangular plate, and threaded mounting holes are formed in the main shock absorber cavity.
Preferably, a boss is arranged on the upper end face of the limiting shock absorber cavity.
Preferably, a limit groove is arranged at the lower part of the inner side of the limit shock absorber cavity.
Preferably, the inner side wall of the cavity of the main shock absorber is provided with an annular groove.
When the connecting mechanism for connecting the vacuum pump and the shock absorber is used, the main shock absorber type cavity is mainly used for placing the main shock absorber, and the limiting shock absorber type cavity is mainly used for placing the limiting shock absorber. The main shock absorber cavity and the limiting shock absorber cavity can prevent the shock absorber from being damaged due to excessive deformation, and the safe and reliable protection shock absorber is achieved, so that the shock absorber can fully and permanently keep a good shock absorption effect.
The boss and the limiting groove can effectively prevent the limiting shock absorber from falling off.
The annular groove can ensure that the main shock absorber can be stably placed in the cavity of the main shock absorber and is not easy to fall off.
The invention has the beneficial effects that: can prevent that the bumper shock absorber excessively warp and arouse the damage, play safe and reliable's protection bumper shock absorber again, make the bumper shock absorber fully and keep its good shock attenuation effect for a long time, make the difficult emergence of bumper shock absorber drop moreover.

FIG. 1 is a schematic diagram of the present invention.
Detailed Description
The following embodiments are specifically illustrated in conjunction with FIG. 1:
the connecting mechanism for connecting the vacuum pump and the shock absorber is characterized by comprising a cup-shaped support plate 1, wherein the cup-shaped support plate 1 is a triangular plate, threaded mounting holes 2 are respectively formed in three corners of the triangular plate, a limiting shock absorber cavity 3 is arranged at one corner of the triangular plate, the threaded mounting holes are located in the limiting shock absorber cavity, a main shock absorber cavity 4 is arranged in the middle of the triangular plate, and threaded mounting holes are formed in the main shock absorber cavity 4.
Preferably, a boss 5 is arranged on the upper end face of the limiting shock absorber cavity 3.
Preferably, a limit groove 6 is arranged at the lower part of the inner side of the limit shock absorber cavity 3.
Preferably, an annular groove 7 is formed in the inner side wall of the cavity of the main shock absorber.
When specifically using, be provided with main bumper shock absorber in the main bumper shock absorber type intracavity, spacing bumper shock absorber is provided with spacing bumper shock absorber in the spacing bumper shock absorber type intracavity. The main damper is arranged to improve the damping capacity of the whole vacuum pump, so that impact energy is effectively absorbed. The limiting shock absorber is arranged to have the following functions: in order to prevent the interference of peripheral parts caused by overlarge rotation quantity, the rotation quantity of the electric vacuum pump is limited. The excircle diameter of the main shock absorber is in interference fit with the cavity of the main shock absorber, and a small amount of water is coated during assembly so as to facilitate assembly. The cup-shaped support plate is fixed on the vacuum pump through self-tapping screws, and threaded mounting holes at 3 corners on the cup-shaped support plate can be assembled with holes at the upper end of the vacuum pump at will, so that the function of 90-degree rotation is realized.
