Description

Electric control carburetor for range extender

Technical Field

The utility model relates to an automatically controlled carburetor, especially an automatically controlled carburetor for extending journey ware.

Background

At present, the existing electronic control carburetor usually adopts a stay cable connection mechanical mode to control the opening and closing of an oil control plunger and a throttle valve and the opening angle of the oil control plunger and the throttle valve; the throttle valve is controlled by a trigger lever directly connected with the rotating shaft, or by an electric heating valve, and is also controlled by an electric brake and a gear.

An invention patent entitled "electronic control device for carburetor" is disclosed in CN100449126C, and has a transmission device connected to a valve that opens and closes an intake passage of a carburetor; an electric motor that drives the opening and closing of the valve through the transmission device; and an electronic control unit that controls an operation of the electric motor, wherein an inside of a housing joined to one side surface of the carburetor is divided into a transmission chamber on a carburetor side and a drive chamber on an opposite side by a partition plate, the transmission is accommodated and held in the transmission chamber, and the electric motor is accommodated and held in the drive chamber. Although this structure can realize electronic control of the carburetor, it adopts an actuator and a gear for control, and has a complicated structure, low sensitivity, and poor reliability.

CN202417739U discloses a utility model named "an electric control carburetor for motorcycle", which includes a carburetor body, an electronic control unit, a plurality of sensors, a gas control valve seat and a stepping motor, wherein the stepping motor drives a gas control valve plunger to reciprocate along the inner wall of a gas control valve plunger hole through a lifting mechanism; a thickening plunger with a sintered thickening sealing ring at the lower end is arranged in the air control valve plunger, a thickening oil nozzle is arranged at the bottom of the air control valve plunger hole, and the opening and closing of the thickening oil nozzle and the size of the opening cross section are controlled by the thickening plunger and a thickening oil needle; the concentration of the rich mixture entering the carburetor and the amount of intake air are controlled. Although the structure can realize the control of the opening and closing of the oil nozzle and the size of the opening section through the stepping motor and the plunger, the control of the throttle valve is still carried out by adopting a cable mode, the structure is complex, and the sensitivity is not high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an automatically controlled carburetor for extending journey ware that simple structure, control sensitivity are high.

The utility model aims at realizing through such technical scheme, an automatically controlled carburetor for range extender, including the carburetor body this internal throttle valve that is provided with the area throttle shaft of carburetor and the oily plunger of accuse of taking the turbine still be provided with step motor A and step motor B on the carburetor body, step motor A passes through elevating system and is connected with the oily plunger of accuse, step motor B is connected with the throttle shaft.

The stepping motor A is vertically arranged above the carburetor body and is connected with the carburetor body through an oil control valve seat; the stepping motor B is horizontally arranged on one side of the carburetor body and is connected with the carburetor body through a mounting plate, and an output shaft of the stepping motor B is coaxially connected with the throttle shaft.

Further described, the lifting mechanism comprises a vertically arranged screw rod, one end of the screw rod is connected with the stepping motor A, and the other end of the screw rod is connected with the oil control plunger.

Since the technical scheme is used, the utility model has the advantages of simple structure, use reliably, low cost, adopt it to realize the switching of glib talker and air throttle and the control of opening angle through step motor, improved sensitivity, guaranteed the reliability that the oil feed was admitted air, improved the job stabilization nature of carburetor.

Drawings

The drawings of the utility model are as follows:

fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a right side view of FIG. 1;

fig. 3 is a sectional view a-a of fig. 1.

Detailed Description

The following detailed description of the embodiments of the present invention will be provided with reference to the accompanying drawings, but the present invention is not limited to these embodiments, and any modifications or substitutions in the basic spirit of the embodiments will still fall within the scope of the present invention as claimed in the appended claims.

Example 1: as shown in fig. 1, 2 and 3, an electronic control carburetor for a range extender comprises a carburetor body 1, a throttle valve 2 with a throttle shaft 9 and an oil control plunger 3 with a turbine are arranged in the carburetor body 1, a stepping motor a4 and a stepping motor B5 are further arranged on the carburetor body 1, the stepping motor a4 is connected with the oil control plunger 3 through a lifting mechanism, and the stepping motor B5 is connected with the throttle shaft 9.

The stepping motor A4 is vertically arranged above the carburetor body 1 and is connected with the carburetor body 1 through an oil control valve seat 6; the stepping motor B5 is horizontally arranged on one side of the carburetor body 1 and is connected with the carburetor body 1 through the mounting plate 7, and the output shaft of the stepping motor B5 is coaxially connected with the throttle shaft 9.

Further describing, the lifting mechanism comprises a vertically arranged screw 8, one end of the screw 8 is connected with the stepping motor a4, and the other end is connected with the oil control plunger 3.

In the utility model, an engine controller outside the carburetor assembly respectively drives a stepping motor A4 and a stepping motor B5 through two sets of stepping motor control wires; the screw 8 is controlled to rotate by the stepping motor A4, the oil control plunger 3 is driven to move up and down, so that the rotating direction and the angle of the oil control plunger 3 are controlled, and the oil inlet amount is controlled; the opening and closing of the throttle valve 2 is controlled by a stepping motor B5, thereby controlling the magnitude of the intake air amount.
