Therefore, if the angle of the headboard is adjustable, similar to the headboard used in hotels, it can provide customers with comfortable living conditions.

[0003] A bed headrest structure with an angle adjustment using an airbag is disclosed in Chinese patent CN212394407U. The bed headrest structure with an angle adjustment using an airbag adjusts the rotation angle of the bed headrest by adjusting the control device to inflate and deflate the adjustment airbag, thereby meeting people's backrest comfort needs. The structure is simple, the adjustment is convenient, and the use is comfortable. However, while solving the problem, the bed headrest structure with an angle adjustment using an airbag has the following defects:

[0004] The top of the headrest is rotatably connected to the headrest bracket via a rotating shaft, so when the angle of the headrest is adjusted, the bottom of the headrest will extend or retract. However, when a person sits on the bed, the person's buttocks are usually close to the bottom of the headrest. Therefore, during the adjustment process, the person also needs to change the sitting position on the bed according to the adjustment of the headrest angle, or the person needs to stand on one side of the bed to first adjust the angle of the headrest and then get on the bed, which makes the overall use more inconvenient and the user experience is poor.

[0024] Embodiment 1:

[0025] like Figure 1-4As shown, it includes a base 1 and a backing plate 2, characterized in that trapezoidal plates 11 are fixedly connected to both sides of the top of the base 1, a positioning seat 12 is fixedly connected to one side of the bottom of the trapezoidal plate 11, a connecting seat 21 is fixedly connected to the bottom of the backing plate 2, through holes are provided on the positioning seat 12 and the connecting seat 21, the positioning seat 12 and the connecting seat 21 are rotatably connected by a pin shaft, the pin shaft passes through the through holes on the positioning seat 12 and the connecting seat 21, thereby realizing the rotatable connection, the top of the trapezoidal plate 11 is fixedly connected to a top plate 13, and the base 1 and the top plate 13 are rotatably connected. There is a screw 3, and bearings 31 are fixedly installed on the top of the base 1 and the bottom of the top plate 13. The base 1 and the top plate 13 are rotatably connected to the two ends of the screw 3 through the bearings 31 respectively. The outer surface of the screw 3 is threadedly connected to a lifting block 4, and a support rod 5 is hinged on one side of the lifting block 4. The end of the support rod 5 away from the lifting block 4 is hinged to the back plate 2. By rotating the screw 3, the lifting block 4 is lifted and lowered, and the angle between the support rod 5 and the back plate 2 changes, thereby changing the angle between the back plate 2 and the base 1, thereby achieving the purpose of adjusting the angle of the back plate 2.

[0026] Preferably, a motor 6 is fixedly installed on one side of the trapezoidal plate 11, and a worm 61 is fixedly connected to the output end of the motor 6. The end of the worm 61 away from the motor 6 is rotatably connected to the other trapezoidal plate 11, and a worm wheel 62 is fixedly connected to the outer surface of the screw 3. The worm 61 is meshed with the worm wheel 62. The motor 6 drives the worm 61 to rotate, and the worm 61 drives the worm wheel 62 to rotate, thereby achieving the purpose of driving the screw 3 to rotate, and the driving method of the worm 61 and the worm wheel 62 can increase the torque of the motor 6 and play a role of deceleration, so that the angle of the back plate 2 can be slowly and stably adjusted.

[0027] Specifically, a back plate 14 is fixedly connected to one side of the trapezoidal plate 11 away from the back plate 2 , so as to seal the back sides of the base 1 , the back plate 2 and the top plate 13 , thereby reducing the entry of dust.

[0028] Specifically, a first positioning block 41 is fixedly connected to one side of the lifting block 4, a second positioning block 22 is fixedly connected to the side of the support plate 2 close to the lifting block 4, both ends of the support rod 5 are fixedly connected to U-shaped blocks 51, and the support rod 5 is hinged to the first positioning block 41 and the second positioning block 22 through the U-shaped blocks 51 at both ends, and the first positioning block 41, the second positioning block 22 and the U-shaped block 51 are all provided with through holes, and the rotation connection is achieved by inserting a pin shaft into the through hole.

[0029] Embodiment 2:

[0030] like Figure 3As shown, on the basis of the first embodiment, a hole groove 23 is opened on one side of the back plate 2, and a groove 24 is fixedly connected to a position corresponding to the hole groove 23 on one side of the back plate 2 close to the screw rod 3, an air bag 25 is fixedly installed inside the groove 24, and a lumbar support 26 is fixedly installed on one side of the air bag 25, and the lumbar support 26 is slidably connected to the inside of the groove 24, and the lumbar support 26 is extended and retracted in the groove 24 by inflating and deflating the air bag 25, so that the protruding length of the lumbar support 26 can be adjusted, and therefore it can be appropriately adjusted according to the needs of the user.

[0031] Specifically, a gas delivery nozzle 7 is fixedly installed on one side of the airbag 25, and the gas delivery nozzle 7 passes through the groove 24. A hose 71 is fixedly installed on the outer surface of the gas delivery nozzle 7. An air pump 72 is fixedly installed on the end of the hose 71 away from the gas delivery nozzle 7. The air pump 72 is fixedly installed above the base 1. The air pump 72 can inflate and deflate the airbag 25 through the hose 71 and the gas delivery nozzle 7.

[0032] The working principle of the utility model is as follows: during production, the outer surfaces of the base 1, the trapezoidal plate 11, the top plate 13 and the back plate 2 are all covered with leather or cloth, and the leather or cloth covered with the back plate 2 is also filled with fillers such as latex or sponge, making it softer and more comfortable to lean on. The gap between the trapezoidal plate 11 and the back plate 2 is connected with a leather strip or a cloth strip, and the gap between the top plate 13 and the back plate 2 is connected with a leather strip or a cloth strip. When adjusting the angle of the back plate 2, the leather strip or the cloth strip is unfolded or bent, which can prevent dust from entering the interior of the headboard;

[0033] When in use, by starting the motor 6, the worm 61 is driven to rotate, thereby driving the screw 3 to rotate through the worm gear 62, so that the lifting block 4 rises or falls, and the support rod 5 pushes or pulls the back board 2 to adjust the angle. Since the hinged part of the back board 2 is located at the bottom, the user only needs to lean on the back board 2 to adjust it, and there is no need to adjust the position of sitting on the bed.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. When adjusting the angle of the backrest 2, the user only needs to sit on the bed and lean on the backrest 2, and then start the motor 6 to drive the screw 3 to rotate, and the lifting block 4 to lift and lower, so as to push and pull the backrest 2 through the support rod 5 to adjust the angle of the backrest 2. The user can feel whether the adjusted angle of the backrest 2 is appropriate at any time, and turn off the motor 6 if it is appropriate. During use, the user does not need to adjust the sitting position on the bed, so it is easy to use and improves the user experience.

[0036] 2. The screw 3 is driven by the worm gear 62 and the worm 61. The driving method of the worm 61 and the worm gear 62 can increase the torque of the motor 6 and play a role in deceleration, so that the angle of the backrest 2 can be adjusted slowly and stably, further improving the user experience.

[0037] 3. By providing the lumbar support 26 and inflating and deflating the airbag 25 through the air pump 72, the lumbar support 26 can be expanded and contracted in the groove 24, so that the protruding length of the lumbar support 26 can be adjusted. Therefore, it can be appropriately adjusted according to the needs of the user, making the user more comfortable to lean on.
