[0023] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0025] The utility model designs a piece of furniture, which includes the adjustment mechanism, which connects the pillow 1 and the furniture body and is used to adjust the angle of the pillow 1 on the furniture body. The furniture of the utility model can be a sofa or a bed, which is not limited in the utility model. The adjustment mechanism is explained in detail below.

[0026] See also Figure 1 and Figure 2 As shown, the utility model designs an adjustment mechanism for adjusting the pillow 1, which includes a frame 9, a first gear 4 and a limiting member, the first gear 4 is connected to the pillow 1, the frame 9 is provided with a second gear 10, the first gear 4 is meshed and connected to the second gear 10, in the natural state, the limiting member is used to lock the first gear 4, the pillow 1 and the frame 9 are in a locked state, in the adjustment state, the limiting member cancels the lock of the first gear 4, the pillow 1 is driven, and the first gear 4 and the second gear 10 rotate.

[0027] Specifically, the adjustment mechanism further includes a first connecting rod, a first end of the first connecting rod is connected to the headrest 1 , and a second end of the first connecting rod is fixedly connected to the first gear 4 .

[0028] It should be noted that, in the natural state, the limiting member locks the first gear 4. Since the first gear 4 and the second gear 10 are meshed, the locking of the first gear 4 also indirectly locks the second gear 10. The first gear 4 is connected to the pillow 1, so the pillow 1 is also maintained at a fixed angle. When the angle of the pillow 1 needs to be adjusted, the limiting member is disengaged from the first gear 4. When the first gear 4 is unlocked, the motor drives the first gear 4 to rotate to drive the pillow 1 to swing, thereby achieving the angle adjustment of the pillow 1. Compared with the adjustment mechanism of the prior art, the adjustment mechanism of the utility model is more in line with the use needs of consumers and has higher universality. Of course, it should be noted that in actual applications, after the first gear 4 is unlocked, the pillow 1 can also be directly driven to achieve the adjustment of the angle of the pillow 1. The utility model does not limit this.

[0029] Specifically, the adjustment mechanism also includes an elastic member 15, and the limiting member includes a first limiting rod 5 and a second limiting rod 6 that are rotatably connected to the first connecting rod. The elastic member 15 connects the first limiting rod 5 and the second limiting rod 6. In the natural state, the elastic member 15 provides an elastic force for the first limiting rod 5 and the second limiting rod 6 to abut against the first gear 4.

[0030] Specifically, the first limiting rod 5 includes a first hook 7, and the second limiting rod 6 includes a second hook 8. In a natural state, the first hook 7 and the second hook 8 respectively abut against the first tooth surface and the second tooth surface of the first gear 4 to lock the first gear 4.

[0031] The elastic member 15 of the utility model is a spring, and the two ends of the spring are respectively connected to the first limiting rod 5 and the second limiting rod 6. In the natural state (unstressed state), the first limiting rod 5 is tightly against the first tooth surface, and the second limiting rod 6 is tightly against the second tooth surface. The limiting member locks the first gear 4. Since the first gear 4 and the second gear 10 are meshed, the locking of the first gear 4 also indirectly locks the second gear 10. The first gear 4 is connected to the pillow 1, so the pillow 1 is also maintained at a fixed angle. When the angle of the pillow 1 needs to be adjusted, the first limiting rod 5 and the second limiting rod 6 are moved away from each other until they are disengaged from the first tooth surface and the second tooth surface, thereby achieving the unlocking of the first gear 4. At this time, the first gear 4 is driven or the pillow 1 is driven, and the angle of the pillow 1 can be adjusted. After adjusting to the required angle, they are released. The first limiting rod 5 and the second limiting rod 6 will be clamped with the first gear 4 again under the action of the elastic member 15 to limit the angle of the pillow 1 to the current angle.

[0032] Specifically, the adjustment mechanism further includes a slider 12 and a second connecting rod 11 . The first end of the second connecting rod 11 is rotatably connected to the second gear 10 , and the second end of the second connecting rod 11 is fixedly connected to the slider 12 . The slider 12 is slidably connected to the frame body 9 .

[0033] Specifically, the adjustment mechanism further includes a slide rail 13 , the slide rail 13 is disposed on the frame 9 , and the slider 12 is slidably connected to the slide rail 13 .

[0034] It should be noted that when the slider 12 slides on the slide rail 13, it can drive the second connecting rod 11 and the second gear 10 to move in the horizontal direction. The second gear 10 is meshed and connected to the first gear 4, and the first gear 4 will also move horizontally with the second gear 10. The first gear 4 is fixedly connected to the pillow 1, so the position of the pillow 1 can be adjusted.

[0035] Specifically, the adjustment mechanism further includes a clamp, which is connected to the slider 12 to lock the slider 12 and the slide rail 13. When the position of the headrest 1 needs to be adjusted, the clamp cancels the contact with the slide rail 13, and the slider 12 can slide along the slide rail 13. After adjusting to the desired position, the clamp is made to contact the slide rail 13, and the slider 12 cannot slide along the slide rail 13, and the position of the headrest 1 is locked.

[0036] Specifically, the adjustment mechanism further includes a buffer 14, which is disposed at both ends of the slide rail 13 to buffer the impact of the slider 12 on the slide rail 13. When the slider 12 slides to both ends of the slide rail 13, due to inertia, the slider 12 may generate a large impact force, and the buffer 14 can effectively absorb the impact force, reduce the degree of damage to the slide rail 13 and the slider 12, and protect their long-term performance. The buffer 14 of the utility model is a sponge member. Of course, in actual applications, people can choose silica gel as the buffer 14, and the utility model does not limit this.

[0037] Specifically, the first connecting rod includes a telescopic portion 2 and a fixed portion 3 , the fixed portion 3 is provided with a slide groove, the first end of the telescopic portion 2 is limited in the slide groove and is slidably connected to the fixed portion 3 , and the second end of the telescopic portion 2 is connected to the pillow 1 .

[0038] Specifically, the adjustment mechanism also includes a connecting piece, the fixing part 3 is provided with a first through hole, the telescopic part 2 is provided with a plurality of second through holes, the plurality of second through holes are spaced apart along the length direction of the telescopic part 2, and the connecting piece passes through the first through hole and any second through hole.

[0039] It should be noted that the slide groove on the fixed part 3 provides a sliding track for the telescopic part 2. When it is necessary to adjust the extension height of the pillow 1 relative to the frame 9, the connecting piece is disengaged from the first through hole and the second through hole, and then the telescopic part 2 is slid along the slide groove. When the pillow 1 reaches the desired extension height, the connecting piece is passed through the first through hole and the second through hole connected to the current first through hole. It is very simple. The first end of the telescopic part 2 is limited in the slide groove, which can prevent the telescopic part 2 from deviating from the track or falling off during the sliding process. Of course, it should be noted that the connecting piece of the utility model is a pin or a bolt. In actual applications, people can also use other parts as connecting pieces, and the utility model does not limit this.
