The utility model proposes a kind of electric hammers.

Referring to Fig. 1, in an embodiment of the utility model, which includes the shell 1 with folder hole, cooperation folder hole The export head 3 of setting, the rotating device 5 being contained in shell 1, hammering device 7 and driving device 4 and with the electricity of driving device 4 The change-over switch 9 of connection, driving device 4 is for driving rotating device 5 and hammering device 7, and rotating device 5 is for driving export head 3 rotations, hammering device 7 is for driving export head 3 axially to hammer, and change-over switch 9 is for controlling 4 start and stop rotating device of driving device 5 and hammering device 7；Electric hammer 10 further includes sensor 2 and controller (not shown), and controller is filled with sensor 2 and driving respectively 4 electrical connections are set, sensor 2 is set on shell 1, the vibration information that sensor 2 is used to detect the vibration of shell 1 and transmission detects To controller, controller is used to drive the power of export head 3 according to the vibration information adjustment driving device 4 received.This implementation In example, vibration information includes shockproofness information, vibration frequency information and vibration duration information.

Specifically, user needs two-handed hand-held electric hammer 10 when using electric hammer 10.The drill bit of required size is installed on institute It states in folder hole, drill bit does the hammering campaign of axial reciprocating with rotating device 5 and hammering device 7, rotates simultaneously.Electric hammer 10 is in work During work, sensor 2 detects the shockproofness of shell 1, vibration frequency and vibration duration, and sensor 2 will Shockproofness information, vibration frequency information and the vibration duration information of the shell 1 detected are sent to controller, and controller receives Judge whether the shockproofness of shell 1 has reached default after to shockproofness information, vibration frequency information and vibration duration information Intensity threshold continues to judge whether the vibration frequency of shell 1 has reached predeterminated frequency if having reached the preset strength threshold value Threshold value continues to judge whether the vibration duration of shell 1 has reached preset duration threshold if having reached the predeterminated frequency threshold value Value, if having reached the preset duration threshold value, controller suitably reduces the power that driving device 4 drives export head 3, to reduce The shockproofness and vibration frequency of shell 1, and then the hand for alleviating user generates the degree of numb fatigue, and human body is protected not to be damaged Wound.

It should be understood that when shockproofness, vibration frequency and the vibration duration of judging shell 1 are described pre- to should be less than If when intensity threshold, the predeterminated frequency threshold value and the preset duration threshold value, or when judge shell 1 shockproofness, Vibration frequency or vibration one or both of duration are to should be less than the preset strength threshold value, the predeterminated frequency threshold value and institute When stating preset duration threshold value, controller is then not required to the power that adjustment driving device 4 drives export head 3.User can be according to electric hammer 10 Actual use situation set the preset strength threshold value, the predeterminated frequency threshold value and the preset duration threshold value.

In the present embodiment, by the way that sensor 2 is arranged, so that electric hammer 10 be made to realize the shell 1 detected according to sensor 2 Shockproofness information, vibration frequency information and vibration duration information adjustment driving device 4 drive the power of export head 3, alleviate and use The hand at family generates the degree of numb fatigue, and protection human body is injury-free.

Fig. 2 is please referred to, shell 1 includes opening up the main part 11 of folder hole, the first handle being connected with main part 11 13 and second handle 15, second handle 15 and the interval of first handle 13 are arranged, and are set to first handle 13 close to the side of folder hole. By setting first handle 13 and second handle 15, to be conducive to user's two-handed hand-held.

In the present embodiment, sensor 2 is set to second handle 15.Second handle 15 is close to folder hole, and the hand of user Second handle 15 is directly held, sensor 2 is set to second handle 15, more directly, more accurately can detect that electric hammer 10 works When the shockproofness of second handle 15, vibration frequency and vibration duration, and then the vibration for reflecting that the hand of user is experienced is strong Degree, vibration frequency and vibration duration.

In the present embodiment, second handle 15 includes connecting rod 151 and holds set 153, and connecting rod 151 is connected with main part 11 It connects, holds set 153 and be sheathed in connecting rod 151, connecting rod 151 is hollow setting, and sensor 2 is set in connecting rod 151.It is preferred that Ground, holding set 153 can be the material that rubber etc. has retractility, so that user be facilitated to hold, reduce suffered vibration.Into one Step ground, sensor 2 are removably mounted on the inner wall of connecting rod 151, are conducive to simplify structure, easy disassembly and maintenance.

In the present embodiment, holding set 153 includes the handle part 1531 connecting with connecting rod 151 and from the two of handle part 1531 Hold the support division 1533 to the direction protrusion setting far from connecting rod 151.By the way that handle part 1531 is arranged, user is thus prevented When holding electric hammer 10, with the vibration of electric hammer 10, relative displacement occurs for the position of hand and handle part 1531.Support division 1533 then rises It is acted on to position limitation protection, prevents the hand of user from excessively causing danger close to export head 3.

In the present embodiment, change-over switch 9 is set to first handle 13 close to one end of main part 11, by by change-over switch 9 It is provided separately with sensor 2, reasonable distribution installation space, while the operation of change-over switch 9 being avoided to interfere sensor 2. Further, change-over switch 9 exposes to first handle 13 close to the side of second handle 15, effectively avoids touchless, facilitates use Family operation.

In another embodiment, sensor 2 is set on the inner wall of shell 1, and sensor 2 is arranged close to folder hole.It will sensing Device 2 is arranged on the inner wall of shell 1 and sensor 2 is arranged close to folder hole, facilitates sensor 2 that can directly detect 10 work of electric hammer Close to the shockproofness of shell 1 of folder hole position, vibration frequency and vibration duration when making, reflect the hand impression of user indirectly Shockproofness, vibration frequency and the vibration duration arrived.Further, sensor 2 is detachably connected with shell 1, is conducive to simplify knot Structure, easy disassembly and maintenance.

The above is only the preferred embodiments of the utility model, and therefore it does not limit the scope of the patent of the utility model, all Under the design of the utility model, equivalent structure transformation made based on the specification and figures of the utility model, or directly/ Other related technical areas are used in indirectly to be included in the scope of patent protection of the utility model.
