A kind of power tool and its composite housing

Abstract

The invention discloses a power tool and its composite casing, wherein the composite casing includes: an inner liner and a surface layer attached to the inner liner, the composite casing includes at least one cushioning area, and the cushioning area is provided with a plurality of A cushioning structure unit, a cushioning structure unit includes: a unit passage formed from the inner liner and passing through it, a unit groove formed from the surface layer and closing one end of the passage; the power tool of the present invention includes: the shell And internal components, the shell includes the composite shell as mentioned above, the surface body is located on the outside of the power tool; the shell includes: a contact portion for holding or / and operating. The composite casing of the present invention forms a plurality of shock-absorbing structural units through the combination of the inner lining body and the surface layer body; the unit channel and the unit groove can weaken the transmission of vibrations in the inner lining body and the surface layer body respectively, so the composite casing of the present invention is adopted Power tools can reduce user fatigue and improve user experience.

Description

technical field [0001] The invention relates to a tool and its shell, in particular to a power tool and its composite shell. Background technique [0002] In power tools, vibrations are often generated due to the operation of internal power components and transmission components. This vibration often affects the user's operating experience, especially the user's hand feeling when holding it. When working for a long time, frequent The vibration of the vibration is easy to make the user feel tired, because it has been overcoming the adverse effects of the vibration in the process of work. This situation is especially obvious on power tools such as sanders and angle grinders, because such tools need to act on certain target areas with working accessories, but the operating mode of their mechanisms will always cause unavoidable vibrations to the body. [0003] In order to solve the above problems, the industry often installs soft materials on the handles of the power tool casin...

Problems solved by technology

[0002] In power tools, vibrations are often generated due to the operation of internal power components and transmission components. This vibration often affects the user's operating experience, especially the user's hand feeling when holding it. When working for a long time, frequent The vibration is easy to make the user feel tired, because it has been overcoming the adverse effects of the vibration during the work process

This situation is especially obvious on power tools such as sanders and angle grinders, because such tools need to act on certain target areas with working accessories, but the operating mode of their mechanisms will always cause unavoidable vibrations on the body

[0003] In order to solve the above problems, the industry often installs soft materials on the handles of the power tool casings to achieve shock absorption through the soft characteristics of the materials themselves. However, if the thickness of the soft materials is too thin, it will be difficult to achieve the ideal shock absorption effect. Thick can make the user difficult to accurately control the power tool and easy to fall off
