Abstract
The utility model relates to a direct current electric tool capable of automatically displaying electric quantity, which belongs to the technical field of electric tools. The electric tool comprises a tool main body provided with a driving motor, a battery device capable of being split from and combined with the tool main body, and an electric quantity display device controlled by a trigger switch, wherein the trigger switch is positioned in a position where the tool main body is triggered when being combined with the battery device. Therefore, as long as the battery device is combined with the tool main body, the electric quantity display device can automatically display the electric quantity of a battery. In this case, once a user starts the electric tool, the electric power storage condition of the battery can be clearly obtained, so as to operate and use the electric tool as appropriate or take charging measures; therefore, the inconvenience that the electric quantity can only be displayed through intentional control is avoided, and the unnecessary trouble arising from the fact that the user forgets watching the electric quantity before using the electric tool is prevented; and the electric tool brings more convenience to the user.
Description
Technical field
The utility model relates to a kind of electric weight show tools, and especially a kind of direct current electric power tools of automatic demonstration electric weight belongs to the electric tool technical field.
Background technology
Be widely used with the direct current electric power tools of dc source as the energy.For the ease of knowing the dump energy of dc source, the electric quantity display device that some existing direct current electric power tools are equipped with, for example application number is that the Chinese patent application of CN200620043878.4 and CN201020231164.2 promptly discloses such device.
No matter be the nickel-cadmium cell electric quantity display device that can only reflect electric weight roughly, still additional electric quantity display function thereby can comparatively accurately reflect the lithium battery quantity display apparatus of electric weight on original safety monitoring circuit base brings convenience all for the user of electric tool.
Yet, understand according to the applicant, existing this type electric tool all needs painstakingly to control---for example pressing by switch---and could show electric weight, so the user is forgotten check electric weight and cause unnecessary trouble, especially when operating occasion, all the more so away from charge power supply.
The utility model content
The purpose of this utility model is: the inconvenience at above-mentioned prior art exists proposes a kind of direct current electric power tools of automatic demonstration electric weight, thereby in case the user enables electric tool, just can show electric weight automatically.
In order to reach above purpose, the utility model show automatically the direct current electric power tools of electric weight comprise tool body with drive motors, with the cell apparatus of the detachable combination of described tool body, and the electric quantity display device that is controlled by trigger switch; Described trigger switch is positioned at the position that is triggered when described tool body and cell apparatus combination.
Therefore, as long as, can make electric quantity display device show the electric weight of battery automatically with cell apparatus and tool body combination.Like this, the user is once enable electric tool, just can come into plain view and learn battery electric power storage situation, take the circumstances into consideration to manipulate or take the charging measure, not only having avoided painstakingly thus, control could show the trifling of electric weight, and prevented to use cause to forget the unnecessary trouble of watching electric weight and causing, more convenient bring to the user.

The specific embodiment
Embodiment one
The direct current electric power tools that present embodiment shows electric weight automatically as depicted in figs. 1 and 2, this electric tool is specially a kind of direct current electric hand drill of battery supply, the cell apparatus 2 that contains the lever lower end of tool body 1 of drive motors and detachable combination is inserted (structure and prior art roughly the same, referring to Fig. 6) herein by horizontal tenon and is made up mutually.Cell apparatus 2 by the power brick lower casing 4 of laying battery 8 and the power brick upper casing 5 that fastens with it constitute.The lock-button 7 that is resisted against on the vertical spring 6 is housed between power brick lower casing 4 and the power brick upper casing 5.This lock-button can lock the relative position of constraint cell apparatus 2 and tool body 1.The side of the power brick lower casing 4 of cell apparatus 2 is provided with LED electric weight display screen 3.
The trigger switch 9 of control electric weight display screen 3 is the pressing switch, is placed on the circuit board 10 that is fixed in the cell apparatus, and is positioned under the elongated end of lock-button 7.When tool body 1 made up with cell apparatus 2 plug-in mountings, lock-button 7 moved down, and elongated end presses down this trigger switch 9, and then triggered the electric weight that LED electric weight display screen 3 shows batteries.
In order to prevent that trigger switch from damaging because of the rigidity active force that is subjected to lock-button repeatedly, the elongated end lower surface bonds of lock-button 7 has gum sponge 11.
Test shows, because as long as with cell apparatus and the combination of tool body plug-in mounting, can make LED electric weight display screen show the electric weight of battery automatically automatically by trigger switch, therefore the user need not painstakingly to control, just come into plain view immediately and learn battery electric power storage situation, thereby taken the circumstances into consideration to manipulate or taked the charging measure, avoided watching many troubles that electric weight causes in advance because of forgeing.
Embodiment two
Present embodiment shows that automatically the direct current electric power tools basic structure of electric weight is identical with embodiment one, difference as shown in Figure 3, trigger switch 9 is for being positioned at the optoelectronic switch under lock-button 7 elongated ends.Its action principle is not difficult to analogize from embodiment one, does not give unnecessary details in addition.
Embodiment three
Present embodiment shows that automatically the direct current electric power tools basic structure of electric weight is identical with embodiment one, difference as shown in Figure 4, trigger switch 9 is for being positioned at the contact switches under lock-button 7 elongated ends.Its action principle and embodiment one roughly the same do not give unnecessary details in addition.
Embodiment four
Present embodiment shows that automatically the direct current electric power tools basic structure of electric weight is identical with embodiment one, difference as shown in Figure 3, trigger switch 9 is for being positioned at the contactless magnetic switch (Hall switch, tongue tube etc.) under the lock-button 7 elongated end magnetic devices.Its action principle also is not difficult not give unnecessary details in addition from embodiment one release.
Embodiment five
Present embodiment shows that automatically the direct current electric power tools of electric weight also is the direct current electric hand drill, be trigger switch 9 as shown in Figure 6 with the difference of the foregoing description, the horizontal tenon that is placed in tool body 1 lever lower end and cell apparatus 2 is inserted track one side, rather than is positioned under the elongated end of lock-button 7.The concrete form of trigger switch 9 can be pressing switch, optoelectronic switch, contact switches, magnetic switch or pressure switch.
In addition to the implementation, the utility model can also have other embodiments.For example, electric tool also can be electric saw, electric hammer, electric scissors etc. except that electric hand drill; Electric quantity display device is not limited to LED display, also can be other alternative such as indicator lamp, digital spot, or even sound; The installation position of display unit both can be the cell apparatus side, also can be placed in the easy look-out station of tool body; Trigger switch can also be placed in other relative motion place of tool body and cell apparatus; Or the like.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
