Description

Technical Field

[0001] The utility model belongs to the technical field of oil pumps, in particular to an environmentally friendly and energy-saving oil pump. Background Art

[0002] Energy conservation and emission reduction are the development trends of modern automobiles. As the core component of the engine lubrication system, the oil pump can greatly improve the economy of the engine by improving its working reliability and energy consumption.

[0003] At present, the oil pump is driven by the crankshaft of the engine. However, when the engine is started, the crankshaft enters a rotating state under the action of the starter motor, and other supporting mechanical parts enter an operating state at the same time. However, the oil sinks into the oil pan at the bottom of the engine when it is stationary for a long time. Even if the oil pump is driven to work synchronously when the engine is started, the oil cannot be quickly pressed into the upper mechanical parts in a very short time to lubricate the mechanical parts as a whole. That is, the oil pump cannot lubricate the mechanical parts in advance before the engine is started, so that the mechanical parts have a certain friction resistance during the operation process at startup, which is easy to cause loss of mechanical components and increase energy consumption at startup.

[0020] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0023] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0024] Reference Figure 1-3 An embodiment of the utility model provides an environmentally friendly and energy-saving oil pump, including an oil pump body, hereinafter referred to as a pump body 1. In addition, the utility model also includes at least one transmission shaft 3, and utilizes the cooperation between the starter motor 2 and the transmission shaft 3, wherein:

[0025] A transmission relationship is established between the transmission shaft 3 and the crankshaft, such as a gear transmission or a pulley assembly transmission, and the transmission shaft 3 can be connected and separated from the pump body 1 through the transmission mechanism 4;

[0026] The transmission mechanism 4 is electrically controlled and connected to the vehicle-mounted ECU and controlled by the ECU;

[0027] A transmission relationship is established between the starter motor 2 and the pump body 1, such as the transmission between the two can still be carried out through a pulley, or through a gear;

[0028] When the engine is started, the starter motor 2 rotates and gradually transmits power to the crankshaft through the linkage mechanism. Due to the delay in power transmission, the starter motor 2 has a transmission relationship with the pump body 1 from the beginning, so it has synchronously driven the pump body 1 to work when it rotates, thereby realizing the supply of engine oil to the mechanical components. After the power is subsequently transmitted to the crankshaft, the oil pump has entered the working state in advance, and the engine oil has lubricated the mechanical components, which is beneficial to reduce the resistance of the mechanical components when starting, thereby reducing energy consumption. In this process, the transmission mechanism 4 separates the pump body 1 and the transmission shaft 3. When the engine is fully started , the starting motor 2 stops working and disconnects the power transmission with the crankshaft. At the same time, the transmission mechanism 4 establishes a transmission relationship between the pump body 1 and the transmission shaft 3, so that a transmission relationship is established between the pump body 1 and the crankshaft, so that after the engine is started, the operation of the pump body 1 is driven by the engine. Due to the establishment of the transmission relationship between the starting motor 2 and the pump body 1, during the normal operation of the engine and the driving process of the pump body 1, the pump body 1 drives the starting motor 2 to continue rotating in the reverse direction, thereby realizing power generation through the starting motor 2. Therefore, through the effect of the utility model, the starting process of the pump body 1 can be reasonably controlled, and the mechanical components can be better protected while saving energy consumption.

[0029] Further, see Figure 3 The utility model further includes a flow detection unit, which is used to detect the oil supply of the pump body 1. The flow detection unit can be a flow meter or other type of detection element arranged in the oil circuit. The flow detection unit is connected to the ECU, so as to feed back the oil supply situation to the ECU. Specifically, in the utility model, the process in which the pump body 1 is driven by the crankshaft and the starter motor 2 is reversely driven by the pump body 1 to generate electricity is defined as the first state; when the ECU controls the transmission mechanism 4 to perform the disconnection action and controls the starter motor 2 to work, the transmission relationship between the crankshaft and the pump body 1 is disconnected, and the starter motor 2 is driven by the crankshaft to generate electricity. The motor 2 drives the pump body 1 to work, and the utility model defines this state as the second state; when the engine speed is low and the pump body 1 works slowly, the oil supply will be reduced. When the flow detection unit detects that the oil supply is too low, it enters the second state under the control of the ECU. At this time, the starter motor 2 can control the rotor of the pump body 1 to run quickly, thereby increasing the oil supply to maintain sufficient lubrication of the mechanical components. When the engine speed enters a normal state, it returns to the first state again, that is, the crankshaft drives the pump body 1 to work, and the starter motor 2 passively rotates to realize the power generation function.

[0030] Furthermore, the utility model can also cooperate with a throttle opening detection unit, which is used to collect throttle opening information and is connected to the starter motor 2 through an electrical signal. This control process is provided by the ECU. Specifically, when the throttle opening increases rapidly, the engine speed will increase rapidly in a short period of time. By collecting such information that the throttle opening increases rapidly, it will be quickly switched from the first state to the second state under the control of the ECU again, and the starter motor 2 will enter the high-speed operation working state again. At this time, the transmission process between the pump body 1 and the crankshaft is disconnected through the transmission mechanism 4, and the starter motor 2 can drive the pump body 1 to achieve high-speed operation again before the engine speed is increased, so as to complete the sufficient supply of engine oil, thereby achieving sufficient lubrication effect for the mechanical components before entering the high-speed operation state.

[0031] Further, see Figure 1 and Figure 2 Regarding the transmission mechanism 4, it includes a clutch plate 401 that is slidably connected to the transmission shaft 3, and the sliding direction of the clutch plate 401 is parallel to the axial direction of the transmission shaft 3. The transmission mechanism 4 also includes a shift fork 402 and a pushing unit acting on the shift fork 402. The shift fork 402 rotates with the clutch plate 401. The clutch plate 401 is used to contact the input shaft of the pump body 1. The pushing unit can adopt an electromagnet-type pushing element or an electric push rod-type control element, which is connected to the ECU by electrical signals. When realizing the transmission between the pump body 1 and the transmission shaft 3, the pushing unit is operated under the control of the ECU to move the shift fork 402 toward one side of the pump body 1, and the clutch plate 401 is in contact with the input shaft of the pump body 1, and the operation of the rotor of the pump body 1 is driven by contact friction. Conversely, when the transmission is disconnected, the pushing unit causes the shift fork 402 to move in the opposite direction, and the clutch plate 401 is separated from the input shaft of the pump body 1.

[0032] Further, see Figure 1 and Figure 2 In order to increase the friction force when the clutch plate 401 contacts the input shaft of the pump body 1, a friction plate 5 is further provided on the end of the input shaft of the pump body 1, which is used to better contact the clutch plate 401, thereby increasing the friction effect during contact.

[0033] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
