Detailed ways

It should be understood that the following specific embodiments are only used to illustrate the present invention rather than to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description, and the words "left", "right", "upper" and "lower" ” refers to the direction in the drawings, and the words “front” and “rear” refer to directions toward or away from the geometric center of a specific component, respectively. The technical solution is clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, those of ordinary skill in the art will not make All other embodiments obtained under the premise of creative work fall within the protection scope of the present invention.

Please refer to FIG. 1 , which is a shock-absorbing base for a motor in this embodiment, including a base shell 1 with a cavity for storing shock-absorbing components, and the top ends of the base shell 1 above the cavity are respectively folded inward for a certain length. There are side plates 2 with the same length as the folded parts 1a just below the folded parts 1a on both sides, and the side plates 2 and the folded parts 1a form a space.

A mounting plate 4 is provided in the cavity of the base shell 1, and the motor body 7 is mounted on the mounting plate 4 through the connecting bolts 5. In order not to affect the compression, the lower ends of the connecting bolts 5 are embedded in the mounting plate 4 and do not protrude. Lower plane of plate 4.

A concave upper counterbore 4a is provided on the lower surface of the mounting plate 4, and a concave counterbore 1b is provided on the bottom plane of the cavity of the base shell 1, and the counterbore 1b is located directly below the upper counterbore 4a.

The main spring 6 is installed in the sinking hole 1b and the upper sinking hole 4a, or the lower end of the main spring 6 is fixed in the sinking hole 1b, and the upper end is movably sleeved in the upper sinking hole 4a, and the mounting plate 4 is under the action of the main spring 6. Move up and down for shock absorption.

The two side elevations of the mounting plate 4 are opposite to the space formed by the side plate 2 and the folded portion 1a. In this space, a plurality of side springs 3 are arranged along the two side elevations of the mounting plate 4. Due to the view, in the figure Only one side spring 3 is drawn on both sides of the mounting plate 4. In fact, the side elevation of the mounting plate 4 has a certain length, so multiple side springs 3 must be set up on each side.

In order to ensure normal operation, after the main spring 6 is compressed, the two side elevations of the mounting plate 4 are always in contact with the side spring 3 on the side; the side spring 3 should also extend out of the side plate 2 after being compressed, so as to ensure the installation The bottom and both sides of the plate 4 are in contact with the spring body, which can effectively dampen the vibration of the motor in the up-down and left-right directions during the working process. The shock-absorbing seat has a good shock-absorbing effect and reduces noise. Therefore, the vibration generated by the engine operation is avoided to disturb the people, which is beneficial to the normal movement of the motor. At the same time, the utility model has the advantages of simple structure, easy manufacture and low cost.
