Description

Technical Field

[0001] This utility model relates to the field of automotive starter technology, and in particular to an automotive starter start-stop control device. Background Technology

[0002] A car starter motor is a car component that converts electrical energy from the battery into mechanical energy to drive the engine flywheel to rotate. It is used to enable the engine to automatically shut off and quickly restart when the car is stopped for a short time, in order to reduce fuel consumption and emissions. Therefore, a car starter motor start-stop control device is used.

[0003] To this end, patent CN216564764U discloses a control device for an automotive starter motor, relating to the field of automotive starter motor technology. This utility model includes a mounting box, with a base on the inner bottom wall of the mounting box. A fastening bolt is installed between the base and the inner bottom wall of the mounting box. The mounting box and the base are threadedly connected to the fastening bolt. A starter motor body is mounted on the top of the base. A rotating shaft is installed at the output end of the starter motor body, and the rotating shaft is fixedly connected to the output end of the starter motor body. A temperature control element, an ignition switch, a control mechanism, a speed adjustment element, and an electromagnetic switch are respectively installed on the outer surface of the starter motor body. This utility model, by incorporating a temperature control element, an ignition switch, a control mechanism, a speed adjustment element, and an electromagnetic switch, can control the operating state of the starter motor. When the starter motor experiences overheating or leakage during startup, the power to the starter motor can be cut off in a timely manner to prevent damage and extend the starter motor's service life.

[0004] Although the aforementioned control device for the car starter motor can prevent damage to the starter motor and thus extend its service life, its applicability is low because it is inconvenient to lubricate, difficult to avoid direct metal-to-metal contact, and unable to effectively reduce the coefficient of friction and reduce mechanical wear. Utility Model Content

[0005] The purpose of this invention is to provide an automotive starter motor start-stop control device to solve the problem of inconvenient lubrication in existing automotive starter motor start-stop control devices.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a start-stop control device for an automobile starter motor, comprising a housing and an end cover;

[0007] One end of the housing is fixed with an end cap, a drive motor shaft is provided inside the housing, a flywheel is provided at the bottom of the end cap, and a control structure is provided on one side of the top of the housing.

[0008] A lubrication structure extends through the top of the end cap;

[0009] The lubrication structure includes an oil cylinder extending through the top of the end cap, an oil drain pipe fixed at the bottom end of the oil cylinder, a piston seat inside the oil cylinder, a piston rod fixed at the top end of the piston seat, and an electric push rod fixed at the top end of one side end cap of the oil cylinder.

[0010] When using this device, the lubrication structure reduces friction and wear, thus improving its applicability; the control structure facilitates start-stop control, further enhancing its ease of use.

[0011] Preferably, the control structure includes an electromagnetic base, a first terminal block, an electromagnetic switch, a second terminal block, a third terminal block, a movable base, a shift fork, a key, a keyway, and a drive gear. The electromagnetic base is fixed to one side of the top of the housing. An electromagnetic switch is installed inside the electromagnetic base. A shift fork is hinged to the bottom of the electromagnetic base. A second terminal block passes through the top of one end of the electromagnetic base. A first terminal block passes through one side of one end of the electromagnetic base. A third terminal block passes through the other side of one end of the electromagnetic base. A movable base is fitted onto the outer side of the drive motor shaft. A drive gear is rotatably connected to one side of the movable base. A keyway is provided inside the drive gear. A key is fixed to the top of the drive motor shaft on one side of the drive gear. When the electromagnetic switch is energized and generates electromagnetic force, the electromagnetic force pushes the movable base to move outside the drive motor shaft via the shift fork. The moved movable base then drives the drive gear to move.

[0012] Preferably, the top end of the shift fork is hinged to one end of the electromagnetic switch, and the bottom end of the shift fork is hinged to the outer side of the movable seat. The shaft key and the drive gear form a sliding structure through the keyway. Under the action of the shaft key and the keyway, when the drive motor shaft rotates, the drive motor shaft will drive the drive gear to rotate, which in turn will drive the flywheel to rotate, thus facilitating starting. When the drive gear separates from the flywheel, it can be stopped easily.

[0013] Preferably, a movable plate is fixed to the top of the electric push rod, and an oil inlet pipe is fixed to one side of the top of the oil cylinder.

[0014] Preferably, the top end of the piston rod extends to the outside of the oil cylinder and is fixedly connected to the bottom end of the movable plate, and the oil discharge pipe is located directly above the flywheel. During the engagement of the drive gear and the flywheel, the electric push rod drives the movable plate to move downward, and the moved movable plate drives the piston seat to move inside the oil cylinder through the piston rod.

[0015] Preferably, a flange is fixed to the end of the oil inlet pipe away from the oil cylinder. At this time, the lubricating oil inside the oil cylinder is transported to the meshing part of the drive gear and flywheel through the oil drain pipe, thereby achieving lubrication and friction reduction. With the help of the flange, it is convenient to connect an external oil pump to the oil inlet pipe, so as to conveniently replenish the lubricating oil inside the oil cylinder and ensure the continuity of lubrication.

[0016] Preferably, one end of the drive motor shaft extends into the interior of the housing and forms a rotating structure with the housing, and the other end of the drive motor shaft extends into the interior of the end cover and forms a rotating structure with the end cover.

[0017] The advantages of the automobile starter motor start-stop control device provided by this utility model are as follows:

[0018] With a lubrication structure, during the meshing of the drive gear and flywheel, the electric push rod drives the movable plate to move downwards. The moved movable plate then drives the piston seat to move inside the oil cylinder via the piston rod. At this time, the lubricating oil inside the oil cylinder is delivered to the meshing part of the drive gear and flywheel through the oil drain pipe, thereby achieving lubrication and friction reduction. With the help of the flange, it is convenient to connect an external oil pump to the oil inlet pipe, thereby facilitating the replenishment of the lubricating oil inside the oil cylinder and ensuring continuous lubrication. This device achieves the function of reducing friction and wear, thereby improving the applicability of the automotive starter motor start-stop control device in use.

[0019] With a control structure, the second terminal is connected to the ignition switch via a connecting wire, the first terminal is connected to the power supply via a connecting wire, and the third terminal is connected to the drive motor shaft via a connecting wire. When the electromagnetic switch is energized and generates electromagnetic force, the electromagnetic force pushes the movable seat to move outside the drive motor shaft via a shift fork. The moved movable seat drives the drive gear to move. Under the action of the shaft key and keyway, when the drive motor shaft rotates, the drive motor shaft drives the drive gear to rotate, which in turn drives the flywheel to rotate, thus facilitating starting. When the drive gear separates from the flywheel, it facilitates stopping. This device realizes the function of easy start-stop control, thereby improving the convenience of using the car starter start-stop control device. Attached Figure Description
