Abstract
A combined housing for a power tool has an inner housing body and an outer layer body attached to the outside of the inner housing body. The combined housing has at least one vibration-suppressing area. The vibration-suppressing area is provided with a plurality of vibration-suppressing structure units and each vibration-suppressing structure unit has a unit channel formed by the inner housing body and a unit groove formed by the outer layer body and arranged on one end of the unit channel. The unit groove and the unit channel of each vibration-suppressing structure unit form a vibration-suppressing cavit, and the outer layer body serves as the outside of the outer housing.
Claims18
A combined housing having at least one vibration-suppressing area, comprising:
- an inner housing body;
- and
- an outer layer body attached to the outside of the inner housing body;
- wherein the vibration-suppressing area is provided with a plurality of vibration-suppressing structure units and each vibration-suppressing structure unit comprises:
- a unit channel formed by the inner housing body, the unit channel extending through the inner housing body;
- and
- a unit groove formed by the outer layer body and arranged on one end of the unit channel;
- wherein the unit groove and the unit channel of each vibration-suppressing structure unit form a vibration-suppressing cavity,
- wherein the inner housing body further comprises a first surface attached to the outer layer body and a second surface opposite to the first surface, the unit channel is a through hole passing through the inner housing body along a central axis, and the through hole has a first end connected with the first surface and a second end connected with the second surface along the central axis,
- wherein the unit groove extends along the central axis, and
- wherein the outer layer body is provided with a plurality of connecting portions at least extending from one vibration-suppressing cavity to another vibration-suppressing cavity, and each connecting portion comprises a first part, a second part, and third part, wherein the first part is accommodated inside one through hole, the second part is accommodated inside another through hole, and the third part connects the first part and the second part.
A power tool, comprising:
- an outer housing;
- and
- an inner working assembly for driving a tool accommodated in the outer housing;
- wherein the outer housing comprises:
- a combined housing having at least one vibration-suppressing area, the combined housing comprising an inner housing body and an outer layer body attached to the outside of the inner housing body, the vibration-suppressing area is provided with a plurality of vibration-suppressing structure units, each vibration-suppressing structure unit comprises a unit channel formed by the inner housing body, the unit channel passing through the entire width of the inner housing body and a unit groove formed by the outer layer body and arranged on one end of the unit channel, the unit groove and the unit channel of each vibration-suppressing structure unit form a vibration-suppressing cavity, and the outer layer body serves as the outside of the outer housing,
- wherein the inner housing body comprises a first surface attached to the outer layer body and a second surface opposite to the first surface, the unit channel is a through hole passing through the inner housing body along a central axis, and the through hole has a first end connected with the first surface and a second end connected with the second surface along the central axis,
- wherein the unit groove extends along the central axis, and
- wherein the outer layer body is provided with a plurality of connecting portions at least extending from one vibration-suppressing cavity to another vibration-suppressing cavity, and each connecting portion comprises a first part, a second part, and third part, wherein the first part is accommodated inside one through hole, the second part is accommodated inside another through hole, and the third part connects the first part and the second part.
