Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-5 As shown, this embodiment provides an oiling device for automotive screen hinges, including a mounting box 100. Multiple mounting seats 101 are fixed on the outer wall of the mounting box 100. A cover plate 102 is fixed on the top surface of the mounting box 100. A worm gear 103 is rotatably connected inside the mounting box 100. A hinge assembly 200 is inserted into the top surface of the cover plate 102.

[0024] The rotating shaft assembly 200 includes a rotating shaft body 201. Two mounting discs 202 are sleeved on the outer peripheral wall of the rotating shaft body 201. One mounting disc 202 is fixedly connected to the rotating shaft body 201, and the other mounting disc 202 is rotatably connected to the outer wall of the rotating shaft body 201. One mounting disc 202 is fixedly connected to the cover plate 102 by a first bolt 105. Two bearings 203 are respectively sleeved on the outer peripheral wall of the rotating shaft body 201. A worm gear 204 is sleeved in the middle of the rotating shaft body 201. The worm gear 204 is meshed with the worm 103.

[0025] An oiling assembly 300 is sleeved on the outer peripheral wall of the rotating shaft body 201. The oiling assembly 300 includes an oiling ring 301, which is mounted on a mounting plate 202 rotatably connected to the outer wall of the rotating shaft body 201. An oil supply pipe 302 is connected to the oiling ring 301.

[0026] A servo motor 109 is installed on the outer wall of the mounting box 100. The output shaft of the servo motor 109 is coaxially connected to the worm gear 103. A waste oil pipe 104 with a valve is connected to the mounting box 100. After the device has been used for a long time, the valve on the waste oil pipe 104 can be opened, and the waste oil accumulated in the mounting box 100 can be discharged through the waste oil pipe 104, so as to realize convenient replacement of waste oil.

[0027] One of the bearings 203 has its outer peripheral wall fixedly connected to the inner wall of the mounting box 100, and the other bearing 203 has its outer peripheral wall fixedly connected to the mounting box 100. An oiling ring 301 is located on the outside of one of the bearings 203. Multiple connecting blocks 106 are installed on the cover plate 102, and second bolts 107 are inserted into the connecting blocks 106. The mounting box 100 is threadedly connected to the second bolts 107 through multiple threaded holes. The cover plate 102 is detachably connected to the mounting box 100 through the connecting blocks 106 and the second bolts 107. The cover plate 102 can be removed by unscrewing the second bolts 107 to facilitate the inspection and maintenance of internal components.

[0028] The mounting box 100 is equipped with a second sealing ring 108, and the side of the cover plate 102 near the mounting box 100 abuts against the outer peripheral wall of the second sealing ring 108; the second sealing ring 108 on the mounting box 100 will abut tightly against the cover plate 102 to prevent the leakage of lubricating oil inside the box and the entry of external impurities.

[0029] The oiling ring 301 has an oil delivery groove 304 inside and multiple oil spray holes 305 on it. The oil delivery pipe 302 is semi-circular and connected to an oil inlet pipe 308. An oil inlet valve 306 is installed on the oil inlet pipe 308, and one end of the oil inlet valve 306 is connected to an oil inlet connector 307. External lubricating oil enters the semi-circular oil delivery pipe 302 through the oil inlet connector 307, the oil inlet valve 306, and the oil inlet pipe 308, and then flows into the oil delivery groove 304 of the oiling ring 301. The oil delivery groove 304 distributes the lubricating oil to the multiple oil spray holes 305, and finally sprays it onto the shaft body 201 and the bearing 203, further improving the uniformity of lubrication.

[0030] Two first sealing rings 303 are embedded in the inner wall of the oiling ring 301. The outer peripheral wall of the first sealing ring 303 is rotatably connected to the outer peripheral wall of the rotating shaft body 201. The two first sealing rings 303 on the inner wall of the oiling ring 301 fit against the rotating shaft body 201 to prevent the lubricating oil in the oiling ring 301 from leaking out of the gap.

[0031] Working principle: The device uses the mounting box 100 as the basic frame, with the cover plate 102 fixed to the top surface of the mounting box 100, and the rotating shaft assembly 200 inserted into the cover plate 102; the rotating shaft body 201 is positioned by two mounting plates 202. The mounting plate 202 fixed on the rotating shaft body 201 facilitates the installation of the car screen, and the other mounting plate 202 is fixed to the cover plate 102 by the first bolt 105 to ensure the stable installation of the rotating shaft assembly 200; at the same time, the rotating shaft body 201 can rotate flexibly through two bearings 203, and the worm gear 204 in the middle meshes with the worm 103 in the mounting box 100 to facilitate the rotation of the rotating shaft body 201;

[0032] The oiling assembly 300 is fitted onto the outer peripheral wall of the rotating shaft body 201 via an oiling ring 301, which is mounted on a rotatable mounting plate 202, ensuring a stable relative position between the oiling ring 301 and the rotating shaft body 201. External lubricating oil enters the interior of the oiling ring 301 through an oil supply pipe 302 connected to the oiling ring 301, and then the oiling ring 301 evenly delivers the lubricating oil to one of the bearings 203 on the outer peripheral wall of the rotating shaft body 201. As the rotating shaft body 201 rotates and the lubricating oil flows, the lubricating oil further enters the interior of the mounting box 100, covering other areas of the rotating shaft body 201 and the surfaces of the meshing worm gear 204 and worm 103, thus completing the lubrication of the transmission components. This avoids dry friction of components due to insufficient lubrication, reduces rotational jamming and abnormal noise, ensures the smooth rotation of the vehicle display screen, ensures more uniform oil film coverage, and improves oiling efficiency and lubrication effect.

[0033] The servo motor 109 drives the worm gear 103 to rotate via its output shaft. The worm gear 103 meshes and drives the worm wheel 204 and the rotating shaft body 201 to rotate, providing stable power for the rotation of the vehicle display screen. The cover plate 102 is detachably connected to the mounting box 100 via the connecting block 106 and the second bolt 107. The cover plate 102 can be removed by unscrewing the second bolt 107, which facilitates the maintenance of internal components. The second sealing ring 108 on the mounting box 100 will tightly abut against the cover plate 102 to prevent the leakage of lubricating oil inside the box and the entry of external impurities.

[0034] After the device has been used for a long time, the valve on the waste oil pipe 104 can be opened to discharge the waste oil accumulated in the installation box 100 through the waste oil pipe 104, realizing convenient replacement of waste oil. The oiling ring 301 is located on the outside of one of the bearings 203, which facilitates the application of lubricating oil to the bearing 203. The two first sealing rings 303 on the inner wall of the oiling ring 301 fit against the shaft body 201 to prevent the lubricating oil in the oiling ring 301 from leaking out through the gap. The external lubricating oil enters the semi-circular oil delivery pipe 302 through the oil inlet connector 307, oil inlet valve 306, and oil inlet pipe 308, and then flows into the oil delivery groove 304 of the oiling ring 301. The oil delivery groove 304 distributes the lubricating oil to multiple oil spray holes 305, and finally sprays it onto the shaft body 201 and the bearing 203, which further improves the uniformity of lubrication. Adjusting the oil inlet valve 306 makes it easy to control the start and stop of oil supply and the flow rate, avoiding waste or insufficient lubricating oil.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
