Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of headrest oiling, in particular to a headrest oiling device. BACKGROUND

[0002] The automobile headrest is a kind of pillow located on the seat of the car. When the vehicle is rear-ended, the human body will fall backward due to inertia. At this time, the pressure of vehicle acceleration or deceleration is concentrated on the fragile neck and head of the human body. The headrest can buffer this and protect the human head, playing an important role in the safety protection of the car. During installation, the headrest rod needs to be installed on the seat. However, due to the large friction between the headrest rod and the seat, the headrest rod usually needs to be smeared with lubricating oil before installation.

[0003] Patent No. CN114011639B discloses a headrest oiling device, which comprises an oil tank, a headrest fixing assembly arranged on the oil tank, and an oiling assembly arranged in the oil tank. The top of the oil tank is provided with an oiling hole. The headrest fixing assembly fixes the headrest and drives the headrest rod to pass through the oiling hole and insert into the oiling assembly containing lubricating oil. The process of inserting the headrest rod into the oiling assembly makes the lubricating oil flow out from the bottom of the oiling assembly. The oiling assembly is rotatably arranged on the surface of the headrest rod and smears oil on the headrest rod during rotation. The oiling assembly makes part of the lubricating oil flow from the top of the oiling assembly to the headrest rod while smearing oil. During the oiling process, the device uses less lubricating oil, which can be continuously recycled and used to avoid waste of lubricating oil. However, the device does not collect and process the excess lubricating oil on the headrest rod after the oiling is completed. If the headrest rod is directly taken out, the lubricating oil on the headrest rod will drip onto the device. If the headrest rod is taken out after waiting for a period of time, the work efficiency will be reduced.

[0004] In view of the problems existing in the prior art, we design a headrest oiling device that can collect excess lubricating oil on the headrest rod. SUMMARY

[0042] Referring to Figure 3 And Figure 10The shaking mechanism 7 comprises a second bevel gear 71, a second rotating shaft 72, a fixed block 73, a shaking frame 74 and a first spring 75. The left part of the box body 1 is rotatably connected with the second rotating shaft 72. The second rotating shaft 72 is rotatably connected with the box body 1. The middle part of the second rotating shaft 72 is a thin rod deviated from the center. The right part of the second rotating shaft 72 is connected with the second bevel gear 71. The first rotating shaft 65 at the left rear side is connected with the second bevel gear 71. The two second bevel gears 71 are engaged. The left part of the box body 1 is connected with the fixed block 73 at the front and rear sides. The two fixed blocks 73 are slidably connected with the shaking frame 74. The shaking frame 74 is used for shaking off the excess lubricating oil on the headrest rod. The shaking frame 74 is slidably connected with the box body 1. The shaking frame 74 is in contact with the second rotating shaft 72. The shaking frame 74 is connected with the box body 1 through the four first springs 75 at the upper part.

[0043] In use, the lubricating oil is fed into the oil tank 61 from the oil inlet pipe 2, and the volume of lubricating oil in the oil tank 61 can be observed by the oil gauge 3. When the oil tank 61 is filled with lubricating oil, the feeding of lubricating oil is stopped, and then the motor 63 is started. The output shaft of the motor 63 drives the right rear first rotating shaft 65 through the first helical gear 64, and the right rear first rotating shaft 65 drives the right front first rotating shaft 65 through the second transmission assembly 68. The rotation of the right first rotating shaft 65 drives the first transmission assembly 66, and in turn drives the left first rotating shaft 65. The first transmission assembly 66 drives the telescopic block 67 during rotation. At this time, the headrest rod can be inserted from the right side of the oiling groove above the box body 1, so that the headrest rod is in contact with the telescopic block 67. Since the telescopic block 67 is internally provided with a spring, the telescopic block 67 can clamp the headrest rod, and can also adapt to headrest rods of different thicknesses. The headrest rod moves to the left under the action of the telescopic block 67. When the headrest rod moves to a position corresponding to the nozzle in the drainage groove 4, the oil pump 62 is started. The oil pump 62 feeds the lubricating oil in the oil tank 61 into the drainage groove 4, and sprays the lubricating oil from the nozzle to the headrest rod. Then, the headrest rod continues to move to the left under the action of the telescopic block 67. When the headrest rod moves into contact with the roller 5, the roller 5 rotates under the action of the headrest rod, so that the lubricating oil on the headrest rod is evenly applied. Then, the headrest rod continues to move to the left, and when it moves to the leftmost side of the box body 1 and separates from the roller 5 and the telescopic block 67, the headrest is in contact with the shaking rod. When the left rear first rotating shaft 65 rotates, the second rotating shaft 72 is driven to rotate by the second helical gear 71. Since the second rotating shaft 72 is a thin rod offset from the center of the circle, the second rotating shaft 72 pushes the shaking frame 74 upward during rotation. The first spring 75 is compressed, and then returns to its original position. Under the action of the first spring 75, the shaking frame 74 moves downward. Thus, the shaking frame 74 moves up and down during the rotation of the second rotating shaft 72, so that the headrest is shaken, and the excess lubricating oil on the headrest rod is shaken off. The lubricating oil flowing down during the shaking and oiling processes flows back into the oil tank 61 along the drainage groove 4. Thus, the excess lubricating oil is collected, and the lubricating oil is fully utilized. After the shaking is completed, the headrest rod is removed, and then the next headrest rod can be placed in the box body 1 for oiling. After all the headrest rods are oiled, the motor 63 and the oil pump 62 are turned off.

[0048] When the headrest rod moves to the left, it will contact the rightmost telescopic plate 92 and push it to open outward, and the third spring 93 on the rightmost side is compressed. When the headrest rod moves to contact the next telescopic plate 92, the next telescopic plate 92 opens outward, and the third spring 93 on the rightmost side resets. Under the resetting action of the third spring 93, the telescopic plate 92 closes inward. In this way, the telescopic plate 92 opens and closes in turn under the movement of the headrest rod, so that the telescopic plate 92 can shield the headrest rod to prevent the lubricating oil from splashing onto the headrest during the oiling process and causing pollution to the headrest.
