Abstract
The utility model discloses an electric drill with a multifunction liquid crystal displaying screen and is characterized in that an electric drill body is provided with the liquid crystal displaying screen, and the liquid crystal displaying screen is connected with a slight controlling testing circuit in the electric drill. The electric drill with a multifunction liquid crystal displaying screen brings very large convenience to a user and can test whether the electric quantity is sufficient before the use firstly. Secondly, the electric drill with a multifunction liquid crystal displaying screen can select the suitable rotation speed, the suitable torque force step position, the electric drill step or the impact step according to different needs of using objects in order to handling a tool safely and rationally. The electric drill with a multifunction liquid crystal displaying screen can also test the temperature of a motor at any time in the use and avoid the motor overheating to cause the damage.
Description
Technical field:
The utility model relates to the technical field of appliance tool, a kind of specifically electric drill that has the liquid crystal display function, and it can carry out micro-control to electric drill and detect.
Background technology:
The function of existing electric drill product is comparatively simple, major part is the electric drill of simple function, the electric weight (segmentation demonstration) that can only simply show battery at most, the duty of itself can't detect control, so often can not bring into play the optimum efficiency of electric drill, also can cause the electric drilling device damage sometimes because of improper use.
Summary of the invention:
The purpose of this utility model is to provide a kind of electric drill with multifunction LCD, its rear portion at the electric drill body goes out to have added LCDs, can accurately show numerical value such as at work voltage of electric drill, temperature, can be according to user mode, correctly select torsion, rotating speed, also can select the duty of electric drill or percussion drill, it has overcome existing product function singleness, shortcoming simple in structure.
To achieve these goals, the technical solution of the utility model is: a kind of electric drill with multifunction LCD, it mainly comprises the electric drill body, it is characterized in that: described electric drill body is provided with LCDs, and the micro-control testing circuit in LCDs and the electric drill body is connected.
The utility model is a kind of new product that microprocessor, LCDs and D.C. electric drill are combined, this product used electronic temperature measurement technology, A D switch technology, microprocessing and lcd technology finish whole show states, this state comprises that battery electric quantity shows (segmentation shows and quantitatively shows), motor temperature shows and using method shows, make the user better understand the duty of electric drill, improved security of products and operability.This product brings great convenience to the user, at first, whether the electric weight that just can check battery before use is sufficient, secondly the difference that can require according to the material of effective object is selected suitable rotating speed, torsion gear (electric drill shelves or impact are sought loopholes), so that safe and reasonable ground operation tool, in addition, in use can also detect the temperature of motor at any time, in order to avoid motor overheating causes damage.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the utility model circuit theory diagrams
Fig. 3 connects block diagram for the utility model circuit
The utility model mainly comprises electric drill shell 1, be arranged on motor and gear case assembly in the electric drill casing, it is characterized in that: described electric drill body is provided with LCDs 8, LCDs is installed in the rear portion of electric drill shell, form 32 degree angles with the electric drill axis, like this for the user provides an operation planar and a visual effect preferably comparatively easily, LCDs is connected with micro-control testing circuit in the electric drill body.Described micro-control testing circuit by microprocessor 2, show to select circuit 3, A D converter 4, voltage detecting circuit 5, temperature sensing circuit 6 form, wherein the output of microprocessor is connected with the input of LCDs, two inputs of microprocessor respectively with show to select circuit, A the output of D converter be connected, A two inputs of D converter be connected with the output of voltage detecting circuit, temperature sensing circuit respectively.The input of temperature sensing circuit is connected with the output of temperature sensor 7.A the D converter the input the temperature/voltage signal, battery electric quantity/voltage signal converts data signal respectively to and sends into microprocessor, microprocessor is then selected signal to the GF button of this data signal person of being used in combination input, through output corresponding driving signal after the Computer Processing, give me a little brightness liquid crystal display screen, temperature sensor is installed in the air outlet place of motor, during electric drill work, motor rotates at a high speed, it carries fan inner heat is constantly blown out, temperature sensor just can detect the temperature of motor internal at the air outlet place, and temperature variation is converted to voltage change, be sent to A the D converter, also be provided with two under the LCDs and touch button, the user can select the LCDs content displayed according to self requirements of one's work, wherein left button is used for the control that show state switches, it has four options, they are respectively: battery electric quantity/motor temperature, use the material steel, timber, concrete, right button is used for the selection of particular content, as the size of pressing drill bit (screw) diameter, how to select the rotating speed and the gear that are fit to.
