Description

Technical Field

[0001] The utility model relates to the technical field of headrest frames, in particular to a sleeping type automobile headrest frame. Background Art

[0002] The car headrest frame is an important part of the car seat, which provides a stable support structure for the headrest. The design of this frame is to ensure that the headrest remains stable during use and can provide adequate support and protection when needed.

[0003] A common headrest frame generally increases its overall firmness through a base frame, and a sliding shaft is installed at the bottom of the base frame. The sliding rail is usually fixed to the seat frame. The height of the headrest can be easily adjusted by sliding the sliding shaft in the sliding rail. When the user is resting, the head will rest on the surface of the headrest frame. However, when the user is sleeping, the head is easily detached from the surface of the headrest, and the user may fall suddenly, affecting the user's rest. At the same time, due to the different sleeping states of the user, there are different requirements for the height of the headrest to lift the head, and the headrest frame is difficult to adjust the height of the user's head when sleeping, which reduces the user's comfort when sleeping. Utility Model Content

[0028] The driving machine 4 is arranged on the upper surface of the base 1, and the rotor of the driving machine 4 is coaxially mounted with an eccentric wheel 5;

[0029] The headrest board 6 is arranged on the front side of the main keel 2, the headrest board 6 is in close contact with the surface of the eccentric wheel 5, and the front side of the headrest board 6 is designed to be arc-shaped;

[0030] The mounting plate 7 is arranged on both sides of the main keel 2. The front of the mounting plate 7 is installed with a limit plate 8. The limit plates 8 are all inclined. Please refer to Figure 1 , sliding shafts 9 are provided on both sides of the bottom of the base 1;

[0031] Starting the driving machine 4 can drive the eccentric wheel 5 to rotate. The eccentric wheel 5 will squeeze the headrest plate 6 when rotating. When the protrusion of the eccentric wheel 5 contacts the surface of the headrest plate 6, the headrest plate 6 will move toward the front of the headrest frame, thereby lifting the user's head and increasing the height of the headrest plate 6, so that the device can be suitable for users who like to use high pillows when sleeping. When the recessed part of the eccentric wheel 5 is toward the headrest plate 6, the headrest plate 6 will move toward the inside of the headrest frame, thereby lowering the height of the headrest plate 6, so that the headrest plate 6 will not lift the user's head, so that the device can be suitable for users who like to use low pillows when sleeping, which is convenient for the user to adjust the height of the headrest plate 6 according to his own sleeping state, thereby improving the user's sleeping comfort. At the same time, the limiting plate 8 can block both sides of the user's head, making it difficult for the user's head to fall off the surface of the headrest plate 6 without affecting the user's sleeping rest.

[0032] See also Figure 5 , connection holes 10 are opened on both sides of the upper surface of the base 1, and a threaded head 11 is installed on the top of the sliding shaft 9. The threaded head 11 is screwed into the inner cavity of the connecting hole 10. Rotating the sliding shaft 9 can drive the threaded head 11 to be removed from the connecting hole 10, so that the user can replace the sliding shaft 9 conveniently.

[0033] A stopper 12 is installed on the upper surface of the sliding shaft 9 . The stopper 12 is annular in design and larger than the surface of the connecting hole 10 . The stopper 12 is used to prevent the sliding shaft 9 from passing through the base 1 .

[0034] See also Figure 3 Mounting blocks 13 are installed on both sides of the upper surface of the base 1, the driving machine 4 is installed on the surface of the mounting block 13 on the left side, and the right side of the eccentric wheel 5 is connected to the surface of the mounting block 13 on the right side through a bearing, so that the driving machine 4 can drive the eccentric wheel 5 to rotate more stably.

When the protrusion of the eccentric wheel 5 contacts the surface of the headrest plate 6, the headrest plate 6 will move to the front of the headrest frame, thereby lifting the user's head and increasing the height of the headrest plate 6, so that the device can be suitable for users who like to use high pillows when sleeping. Then, when the concave part of the eccentric wheel 5 faces the headrest plate 6, the headrest plate 6 will move to the inside of the headrest frame. When the protrusion of the eccentric wheel 5 separates from the headrest plate 6, the reset spring 17 will squeeze the connecting frame 16, thereby driving the headrest The plate 6 is retracted and in close contact with the surface of the eccentric wheel 5, thereby lowering the height of the headrest plate 6 so that the headrest plate 6 will not lift the user's head, thereby making the device suitable for users who like to sleep with a low pillow, and facilitating the user to adjust the height of the headrest plate 6 according to their own sleeping state, thereby improving the user's sleeping comfort. Finally, the limiting plate 8 can block both sides of the user's head, making it difficult for the user's head to separate from the surface of the headrest plate 6 and not affecting the user's sleep. The rotating slide shaft 9 can drive the threaded head 11 to be removed from the connecting hole 10, thereby facilitating the user to replace the slide shaft 9.
