The specific embodiment
Referring to figs. 1 through Fig. 4 embodiment of the present invention is described.The impact driver 1 of this embodiment possesses battery department of assembly 10, handle portion 20, circuit substrate 30 and operating portion 40.Through battery department of assembly 10 and handle portion 20 being formed as one resinous left-half shell 50L and right half part shell 50R assembling; This resinous left-half shell 50L has the left part of battery department of assembly 10 and the left part of handle portion 20, and this right half part shell 50R has the right portions of battery department of assembly 10 and the right portions of handle portion 20.In addition, impact driver 1 is an example of rechargeable power tool of the present invention, and left-half shell 50L and right half part shell 50R are two examples cutting apart shell of the present invention.
The battery pack B of approximate rectangular shape is assembled in dismounting freely in battery department of assembly 10.Screw thread from the left surface of top view in battery department of assembly 10 is equipped with the hook F (with reference to Fig. 3 and Fig. 4) on the belt that impact driver 1 is hung over the operator.Handle portion 20 forms from the upper surface of battery department of assembly 10 and projects upwards.Be provided with main part (not shown) continuously in the upper end of handle portion 20, this main part is equipped with motor, the rotation of motor is converted into the rotation impact force and is delivered to the hit agency etc. of front end tool.In addition, battery department of assembly 10 is examples of department of assembly of the present invention.
As shown in Figure 2, circuit substrate 30 in the inner space 11 of battery department of assembly 10, be disposed at handle portion 20 root 22 near.The meaning of this root 22 is the positions that are equivalent to the boundary vicinity of handle portion 20 and battery department of assembly 10.Circuit substrate 30 is held in housing 31 by the resin casting mold.Like Fig. 2 and shown in Figure 4, through with the integrally formed rib 51 of the inner surface of left-half shell 50L and with the lower surface of integrally formed rib 52 support housings 31 of the inner surface of right half part shell 50R, housing 31 is assembled in inner space 11.
As shown in Figure 1, form low-lying 34 of rectangle at the upper surface of housing 31, the resinous support 35 outstanding from low-lying 34 bottom surface is integrally formed with low-lying 34 rear side internal face.As shown in Figure 3, support 35 is arranged at position under the root 22 of the interface 23 of left-half shell 50L and right half part shell 50R in inner space 11, approaching with respect to the lower surface of battery department of assembly 10 with the mode that stays short space.On the other hand, like Fig. 3 and shown in Figure 4, be formed with the recess 37 of rectangle at the back side of housing 31.This recess 37 can ccontaining and installation IC tag 38.Before housing 31 is installed on inner space 11, IC tag 38 is installed on recess 37 in advance.This IC tag 38 possesses the antenna of IC chip and coiled type, and the IC chip possesses memory, control part.With the IC chip intrinsic ID etc. be stored in the memory of IC chip.Control part is according to the instruction that receives from IC tag reader/Write via above-mentioned antenna, and control store is in the transmission of the information of memory or be stored in the reception of the information of memory.In addition, recess 37 is examples of installation portion of the present invention, the IC chip intrinsic ID be rechargeable power tool of the present invention an example of intrinsic identifying information.
In addition, like Fig. 1 and shown in Figure 2, on the upper surface of battery department of assembly 10, position directly over the position that disposes housing 31 is formed with arrival root 22 and the peristome 15 of opening.Operating portion 40 is installed on peristome 15.Operating portion 40 is made up of guidance panel, and the upper surface of this guidance panel disposes various action buttons, display lamp.In this embodiment, impact force switching push button, expression rotation that the switching rotation impacts intensity of force impact the intensity display lamp of intensity of force and show that the battery allowance display lamp of the battery allowance of battery pack B is disposed at the upper surface of guidance panel.If press the impact force switching push button, then be equipped on the control circuit work of circuit substrate 30, the intensity display lamp shows that the rotation that sets impacts intensity of force (strong, in, weak) when setting rotation and impact intensity of force.
In this embodiment, even if owing to for example impact driver 1 error is fallen and handle portion 20 is applied impulsive force, support 35 also can support and stop that following the bringing in of the root 22 of handle portion 20 prevents that circuit substrate 30 from damaging.Below, to support 35 supporting and stop that the action of the lower end of root 22 describes.
Consider owing to the peristome 15 that is provided with the mechanical strength reduction that makes root 22 in battery department of assembly 10, so if handle portion 20 is applied impulsive force, then root 22 will get into the inner space 11 of battery department of assembly 10.Even if in this case, be located at root 22 under the support 35 of position can supporting and the lower end that stops root 22.Thus, support 35 absorbs and relaxes the impulsive force that receives from root 22.In addition, also can absorb and relax this impulsive force with support 35 integrally formed housings 31.
In addition, consider that displacement takes place for example to receive impulsive force between any chance owing to left-half shell 50L or right half part shell 50R, thus the situation that interface 23 will stagger.Even if in this case, be located at the lower end of root 22 of right portions of lower end or handle portion 20 of root 22 that under the root 22 of interface 23 support 35 of position also can stop the left part of handle portion 20.Thus, support 35 can absorb and relax the impulsive force that receives from each root 22.
(effect of this embodiment)
In the impact driver 1 of this embodiment; Even if root 22 will be got under the situation of inner space 11 owing to handle portion 20 having been applied impulsive force; Support 35 also can stop the lower end of root 22, prevents that 22 pairs of circuit substrates 30 of root from directly applying impulsive force.Therefore, can prevent effectively that circuit substrate 30 from damaging.
In addition; Even if receiving impulsive force displacement taking place owing to left-half shell 50L or right half part shell 50R any one; Thereby under the situation that interface 23 will stagger, thereby support 35 can stop that also the lower end of root 22 of right portions of lower end or handle portion 20 of root 22 of the left part of handle portion 20 can suppress staggering of interface 23.
Further, through under the state that IC tag is installed in advance recess 37, housing 31 being assembled in inner space 11, can meanwhile IC tag 38 be assembled in inner space 11.Therefore, IC tag 38 becomes easy with respect to the assembling operation of rechargeable power tool 1.
The invention is not restricted to above-mentioned embodiment, in the scope of the aim that does not break away from invention, can suitably change and implement the part of structure.Though be that support 35 and housing 31 are formed in above-mentioned embodiment; But be not limited thereto; Support 35 also can be after forming with respect to housing 31 splits, through being disposed at position under the root 22 of interface 23 with bonding grade of housing 31.
In addition, support 35 is not limited to resin system, also can be formed by elastomeric elements such as synthetic rubber.And, be not limited to impact driver, can also apply the present invention to rechargeable electric tools such as electric drill.
