Technical Field

[0001] The utility model relates to the technical field related to automobile seat assembly, in particular to a silicone oil smearing device for a seat headrest. Background Art

[0002] The headrest is an important component of the car seat, and is a driving comfort configuration and safety protection product. When a vehicle is rear-ended, the human body will fall backwards due to inertia. At this time, the pressure of the vehicle's acceleration or deceleration is concentrated on the human body's fragile neck and head, and the headrest plays a buffering role to protect the human head.

[0003] When manufacturing and installing the headrest, the headrest rod is usually inserted into the installation hole above the seat. In actual use, the headrest can also be automatically adjusted in two dimensions on the seat through the headrest rod. During assembly, if the headrest rod is directly inserted into the seat, it will be affected by greater resistance, so the headrest rod needs to be lubricated. Silicone oil will be used to apply to the surface of the headrest rod to reduce friction and resistance, making it easier to install and adjust the headrest rod.

[0004] Traditionally, the headrest rod is lubricated in the pilot production line. Figure 2 As shown, by opening an oiling hole 6 on the oil storage tank 5, the headrest rod 7 is inserted into the oiling hole 6, and the surface of the headrest rod 7 is smeared. However, the silicone oil applied by this application method is in a paste-like state, and the applied silicone oil is usually thick. When the headrest rod 7 is inserted into the seat, excess silicone oil will be squeezed out from the mounting hole of the headrest rod 7 and remain on the seat to cause pollution, which is difficult to clean and will result in a waste of silicone oil. Utility Model Content

[0005] The utility model aims to provide a seat headrest silicone oil coating device, which can solve the problem that silicone oil coating on the headrest rod is thick, resulting in silicone oil waste and excess silicone oil remaining on the seat to cause pollution.

[0006] To this end, the technical solution adopted by the utility model is: a seat headrest silicone oil smearing device, including an oil storage tank, one end of the oil storage tank is provided with an air inlet, and the other end is provided with an oil outlet, the oil outlet is connected to the rear end of a hollow oil outlet pipe, the front end of the oil outlet pipe is closed, and oil outlet holes are arranged at intervals on the side wall of the oil outlet pipe, the aperture size of the oil outlet hole is 1-2mm, the air inlet is connected to an air intake pipe, the outer diameter of the oil outlet pipe is the same as the outer diameter of the car seat headrest rod, the length of the oil outlet pipe shall not be less than the depth of the car seat headrest rod mounting hole, when the oil outlet pipe is inserted into the headrest rod mounting hole, the oil outlet hole is located in the car seat headrest rod mounting hole, and the air intake pressure of the air inlet can ensure that the silicone oil in the oil outlet pipe is sprayed out in a mist form.

[0007] More preferably, the diameter of the oil outlet hole is 1.5 mm. The silicone oil sprayed out of the 1.5 mm oil outlet hole is in a mist form, and the atomized silicone oil can be better diffused in the mounting hole of the seat, thereby ensuring that the silicone oil inside the mounting hole can just ensure the smooth installation of the headrest rod and subsequent adjustment.

[0008] More preferably, the oil outlet hole is arranged spirally around the oil outlet pipe. When the oil outlet hole is arranged spirally on the oil outlet pipe, the silicone oil is sprayed more evenly through the oil outlet hole, and the covering effect in the headrest rod mounting hole on the car seat is better.

[0009] More preferably, a valve is provided at the oil outlet of the oil storage tank to control the spraying of the silicone oil and prevent the silicone oil from leaking when the silicone oil is not sprayed, thereby preventing the silicone oil from being wasted.
