Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, and particularly relates to a motor gear transmission device for an automobile electronic device. Background Technique

[0002] Motor gear transmission is a mechanical transmission system that achieves power transmission and speed conversion through the combination of a motor and gears. A motor is a device that converts electrical energy into mechanical energy, while a gear is a mechanical component that transmits power and changes speed through gear meshing. Its transmission ratio is accurate, the efficiency is high, the structure is compact, and the work is reliable.

[0003] A motor gear transmission device for an automobile electronic device disclosed in the Chinese utility model patent application publication specification CN211117511U. Although the oil storage cavity of this utility model can store lubricating oil, and the oil guiding gear dips the lubricating oil, so that the lubricating oil can contact the driving gear and be transmitted from the driving gear to the driven gear, making the gear transmission device always in a lubricated state. When the gears are transmitted, in order to reduce friction, reduce the power loss of the motor, and improve the transmission efficiency. However, the gear oil is arranged in the oil storage cavity. When lubricating the gears, all the gear oil is recycled. The gear oil works in the mechanical transmission system for a long time and will be affected by high temperature, and is prone to generate oxidation products due to thermal oxidation, resulting in the deterioration of the gear oil. After the gear oil deteriorates, its lubricating performance, anti-wear performance, etc. will decline, resulting in abnormal operation of the mechanical transmission system, problems such as poor gear meshing, increased noise, and reduced transmission efficiency, and even damage to mechanical parts. After the gear oil of this utility model deteriorates, it is necessary to replace the gear oil in the oil storage cavity, which has the disadvantage of relatively wasting gear oil, and the gear oil is transmitted from bottom to top, resulting in a relatively poor lubrication effect.

[0013] (III) Beneficial effects

[0014] The utility model provides a motor gear transmission device for an automotive electronic device, which has the following beneficial effects:

[0015] 1. The motor gear transmission device of this automotive electronic device is equipped with the effect of automatically adding gear oil to the gears through the settings of a sealing partition, a spring, a mounting plate, a conical guide rod, a conical groove, a funnel, a fixing plate, and a cam. When in use, the drive motor drives the rotating shaft and the driving gear to rotate. The driving gear meshes with the driven gear, driving the transmission shaft to rotate. During the rotation of the transmission shaft, the cam is driven to rotate. Gear oil is injected above the sealing partition. When the protruding part of the cam contacts the lower surface of the fixing plate during rotation, with the rotation of the cam, the fixing plate will be driven to move upward. When the fixing plate moves, the oil hole moves together. The oil hole drives the conical guide rod to move upward through a connecting rod, causing the conical guide rod inserted in the conical groove to disengage from the conical groove. At the same time, the sealing gasket separates from the sealing partition. At this time, since the conical guide rod and the conical groove are conical, as the conical guide rod leaves the conical groove, the gear oil above the sealing partition flows downward through the gap between the conical guide rod and the conical groove. Since the upward movement stroke of the conical guide rod is small, the amount of gear oil flowing downward each time is limited. Then, with the subsequent rotation of the transmission shaft, the gear oil gradually flows out downward from the gap between the conical guide rod and the conical groove. The flowing gear oil then passes through the oil hole and flows onto the surface of the driven gear. The driven gear and the driving gear mesh with each other, covering the gears with gear oil. When the protruding part of the cam leaves the fixing plate, at this time, under the action of the spring, through the mounting plate, the conical guide rod is inserted back into the conical groove again. At the same time, the sealing gasket abuts against the upper surface of the sealing partition to seal this place, preventing the gear oil from leaking downward continuously. Each time the conical guide rod and the conical groove separate and combine, a part of the gear oil can flow downward, ensuring that the driven gear and the driving gear are always lubricated. At the same time, the remaining gear oil remains in the space above the sealing partition and is not prone to deterioration. At the same time, the staff can select conical guide rods and conical grooves with corresponding taper according to the demand for gear oil. The larger the taper, the higher the oil output, avoiding excessive use of gear oil, and thus achieving a better purpose of automatically lubricating the gears. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to achieve a better purpose of automatically lubricating the gears, during use, the drive motor 4 drives the rotating shaft 5 and the driving gear 6 to rotate. The driving gear 6 meshes with the driven wheel 8 to drive the transmission shaft 7 to rotate. During the rotation of the transmission shaft 7, the cam 19 is driven to rotate. Gear oil is injected into the upper part of the sealing partition 9. When the protruding part of the cam 19 contacts the lower surface of the fixed plate 18 during rotation, with the rotation of the cam 19, the fixed plate 18 will be driven to move upward. When the fixed plate 18 moves, the oil hole 17 will be driven to move together. The oil hole 17 then drives the conical guide rod 13 to move upward through the connecting rod 131, so that the conical guide rod 13 inserted into the conical groove 14 disengages from the conical groove 14. At the same time, the sealing gasket 15 separates from the sealing partition 9.

Since the upward movement stroke of the conical guide rod 13 is small, the amount of gear oil flowing downward each time is limited. Then, with the subsequent rotation of the transmission shaft 7, the gear oil gradually flows out downward from the gap between the conical guide rod 13 and the conical groove 14. The flowing-out gear oil then passes through the oil hole 17 and flows to the surface of the driven wheel 8. The driven wheel 8 meshes with the driving gear 6, so that the gear oil covers the gears. When the protruding part of the cam 19 leaves the fixed plate 18, at this time, under the action of the spring 11, through the mounting plate 12, the conical guide rod 13 is inserted back into the conical groove 14 again. At the same time, the sealing gasket 15 abuts against the upper surface of the sealing partition 9 to seal this place and prevent the gear oil from leaking downward continuously. Each time the conical guide rod 13 and the conical groove 14 are separated and combined, a part of the gear oil can flow downward, ensuring that the driven wheel 8 and the driving gear 6 are always lubricated. At the same time, the remaining gear oil remains in the space above the sealing partition 9 and is not prone to deterioration. At the same time, the staff can select the conical guide rod 13 and the conical groove 14 with corresponding taper according to the demand of the gear oil. The larger the taper, the higher the oil output, avoiding excessive use of gear oil, and thus achieving a better purpose of automatically lubricating the gears.

[0025] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
