Description

Technical Field

[0001] The utility model relates to a sofa, and more specifically, to a sofa with improved structure and high comfort. Background Art

[0002] The origin of the sofa can be traced back to ancient Egypt around 2000 BC, but the truly soft-packed sofa appeared in the late 16th to early 17th century. At that time, the sofa mainly used natural elastic materials such as horsehair, poultry feathers, and plant fluff as fillers, and the outside was covered with fabrics such as velvet and embroidery to form a soft human contact surface. Now, the sofa has undergone a large number of innovations in terms of both materials and structural shapes. As the main carrier for receiving guests at home or in the office, the functionality of the sofa has always been the focus of research by designers.

[0003] Currently, the structures of most sofas on the market are fixed. The backrest of the sofa usually uses elastic pillows to support the user's back to meet the usage needs of people of different heights or weights. Although these elastic pillows can enhance the comfort of the sitting posture of the sofa to a certain extent, due to the fixed structure of the sofa, it cannot meet the user's needs for the lying posture. Therefore, most current users rest on the sofa in a side-lying position and use the sofa armrest as a headrest. Also, since the height of the armrest generally does not meet the support height of the head when the human body is in a lying posture, it will reduce the comfort of the user.

[0004] In response to the above problems, a sofa for improving comfort with the existing publication number CN218390404U includes a support base, a backrest, armrests, and an adjustment component for adjusting the armrests. At least four support blocks are provided at the bottom of the support base. Among them, two armrests are symmetrically arranged, the backrest is rotatably connected to the support base, and the adjustment component includes a rotating member for adjusting the armrests. Both armrests are rotatably connected to the support base through the rotating member.

[0005] The sofa of the above solution has the effect of making the height of the armrest meet the height when the human body is in a lying posture, thereby improving the comfort of the user when lying on the side.

[0006] At the same time, the utility model proposes a new solution to solve the problem that most users rest on the sofa in a side-lying position and use the sofa armrest as a headrest, and the height of the armrest generally does not meet the support height of the head when the human body is in a lying posture, reducing the comfort of the user. Summary of the Utility Model

[0007] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a sofa with improved structure and high comfort, which can adjust the setting position of the armrest so that when the user lies on the sofa, the position of the armrest can be used for the head to rest on without discomfort.

[0008] The above technical purpose of the present utility model is achieved through the following technical solutions: A sofa with improved structure and high comfort includes a sofa body and armrests provided at both ends of the sofa body. The armrests are rotatably connected to the sofa body. A adjusting component for adjusting the setting angle of the armrest is provided on the sofa body. The adjusting component includes a forward and reverse switch provided on the sofa body, a motor electrically connected to the forward and reverse switch, a first gear fixedly connected to the output shaft of the motor, a second gear meshing with the first gear, and a rotating shaft fixedly connected to the second gear. The rotating shaft penetrates inside the armrest and is fixedly connected to the armrest. A part of the rotating shaft extends outside the armrest and is fixedly connected to the second gear.

[0009] By adopting the above technical solutions, when the user lies on the sofa body, if it is necessary to adjust the position of the armrest of the sofa body so that the armrest fits the user's head to increase the comfort of the user lying on the sofa body, the user needs to drive the forward and reverse switch to turn on the motor, so that the first gear connected to the output shaft of the motor will start to rotate. After the first gear rotates, it can drive the second gear meshing with it to rotate, and then drive the armrest fixedly connected to the second gear through the rotating shaft to rotate. When the angle of the armrest is rotated to a suitable position, the forward and reverse switch is turned off to stop the motor from rotating. At this time, the user can lie on the sofa body more comfortably. When waiting for the sofa body to be used normally, the user can press the forward and reverse switch again to make the output shaft of the motor rotate in the reverse direction, which can drive the first gear and the second gear to rotate counterclockwise. At this time, the armrest will rotate on the sofa body to the initial state under the rotation of the second gear, which is convenient for the normal use of the sofa body and also convenient for adjusting the armrest of the sofa body, improving the comfort of the user lying on the sofa body.

[0010] The present utility model is further provided as: A dust-proof box is provided on the sofa body. The motor, the first gear, the second gear and the rotating shaft are all arranged inside the dust-proof box. The forward and reverse switch is arranged outside the dust-proof box corresponding to the position of the motor. A rotating groove for the rotating shaft to rotate is opened inside the dust-proof box.

[0011] By adopting the above technical solution, the dust-proof box is used to cover and protect the motor, the first gear, the second gear and the rotating shaft, preventing the motor, the first gear, the second gear and the rotating shaft from being exposed and causing these components to be contaminated with dust, which affects the normal working efficiency. When the motor drives the first gear and the second gear to rotate and drives the rotating shaft to rotate, the rotating shaft passes through the rotating groove and is fixed to the armrest outside the dust-proof box, thereby protecting the adjustment assembly and increasing the service life of the adjustment assembly.

[0012] The present utility model is further configured as: a limiting block is protrudingly provided on the rotating shaft, and a limiting groove for the limiting block to move is provided on the side wall of the rotating groove.

[0013] By adopting the above technical solution, the limiting block rotates in the limiting groove as the rotating shaft rotates, so that the rotating shaft is in full contact with the dust-proof box, and the rotating shaft will not deviate or vibrate greatly during the rotation process, which affects the normal rotation efficiency of the rotating groove, and the rotating shaft will not be separated from the dust-proof box.

[0014] The present utility model is further configured as: a ball is rotatably connected to the limiting block, and the ball is in contact with the surface of the limiting groove.

[0015] By adopting the above technical solution, the ball will rotate on the limiting block along the inner wall of the limiting groove as the limiting block rotates, which can reduce the friction between the limiting block and the dust-proof box, thereby improving the rotation efficiency of the rotating shaft.

[0016] The present utility model is further configured as: a turntable is fixedly connected to one end of the rotating shaft away from the second gear, and an inner groove for the turntable to move is provided on the sofa body.

[0017] By adopting the above technical solution, the turntable will rotate as the rotating shaft rotates and rotate along the inner wall of the inner groove, and the turntable is restricted in the inner groove and will not deviate, so that the process of adjusting the angle of the armrest will be more stable, and at the same time, it can play a certain supporting effect on the armrest.

[0018] The present utility model is further configured as: a plurality of elastic blocks are protrudingly provided on the outer peripheral wall of the turntable and are distributed in an annular array, and a plurality of clamping grooves for the elastic blocks to be clamped into are provided on the inner groove, and the number of the plurality of clamping grooves is the same as the number of teeth of the second gear.

[0019] By adopting the above technical solution, several elastic blocks on the turntable will rotate as the turntable rotates. And as the second gear rotates, the turntable will rotate at the same angle as the second gear. The second gear and the first gear are both meshed tooth by tooth to realize the rotation between the two. When the second gear rotates to a suitable position as the first gear rotates, the elastic blocks on the turntable will also be correspondingly clamped into the corresponding card slots, thereby further restricting the position of the turntable, and the turntable plays a certain supporting effect to ensure the stability of the rotating shaft and the armrest during the rotation process.

[0020] The present utility model is further configured that: several of the elastic blocks are all hemispherical.

[0021] By adopting the above technical solution, the elastic blocks can be easily clamped into the card slots and slid out of the card slots, and can facilitate the normal rotation efficiency of the turntable.

[0022] To sum up, the present utility model has the following beneficial effects: Under the action of the adjustment component, the setting position of the armrest can be adjusted, so that when the user lies on the sofa, the position of the armrest can be used for the head to rest on without discomfort. Furthermore, it can facilitate the user to lie on the side on the sofa, increasing the comfort of the user. Description of the Drawings

[0031] A sofa with improved structure and high comfort, referring to Figures 1 - 3 , includes a sofa body 1 and armrests 2 provided at both ends of the sofa body 1. The armrests 2 are rotatably connected to the sofa body 1. A adjusting component for adjusting the setting angle of the armrests 2 is provided on the sofa body 1. The adjusting component includes a forward and reverse switch 4 provided on the sofa body 1, a motor 5 electrically connected to the forward and reverse switch 4, a first gear 6 fixedly connected to the output shaft of the motor 5, a second gear 7 meshing with the first gear 6, and a rotating shaft 8 fixedly connected to the second gear 7. The rotating shaft 8 penetrates inside the armrest 2 and is fixedly connected to the armrest 2. A part of the rotating shaft 8 extends outside the armrest 2 and is fixedly connected to the second gear 7.

[0032] A dust-proof box 3 is provided on the sofa body 1. The motor 5, the first gear 6, the second gear 7 and the rotating shaft 8 are all arranged inside the dust-proof box 3. The forward and reverse switch 4 is arranged outside the dust-proof box 3 corresponding to the position of the motor 5. A rotating groove 14 for the rotating shaft 8 to rotate is opened inside the dust-proof box 3.

[0033] A limiting block 12 is prominently provided on the rotating shaft 8, and the thickness of the limiting block 12 is smaller than that of the rotating shaft 8. A limiting groove 15 for the limiting block 12 to move is provided on the side wall of the rotating groove 14, so that the inner diameter of the limiting groove 15 is also smaller than that inside the rotating groove 14, ensuring that the limiting block 12 is always inserted into the limiting groove 15. A ball 13 is rotatably connected to the limiting block 12, and the ball 13 is in contact with the surface of the limiting groove 15.

[0034] One end of the rotating shaft 8 away from the second gear 7 is fixedly connected with a turntable 9, and an inner groove for the turntable 9 to move is provided on the sofa body 1.

[0035] A plurality of elastic blocks 10 distributed in an annular array are prominently provided on the outer peripheral wall of the turntable 9, and a plurality of clamping grooves 11 for the elastic blocks 10 to be clamped into are provided on the inner groove. The number of the plurality of clamping grooves 11 is the same as the number of teeth of the second gear 7, and the plurality of elastic blocks 10 are all hemispherical.

[0036] Working principle: When the user lies on the sofa body 1, if it is necessary to adjust the position of the armrest 2 of the sofa body 1 so that the armrest 2 fits the user's head to increase the comfort of the user lying on the sofa body 1, the user needs to drive the forward and reverse switch 4 to turn on the motor 5, so that the first gear 6 connected to the output shaft of the motor 5 will start to rotate. After the first gear 6 rotates, it can drive the second gear 7 meshing with it to rotate, and then drive the armrest 2 fixed together with the second gear 7 through the rotating shaft 8 to rotate. When the set angle of the armrest 2 rotates to a suitable position, the forward and reverse switch 4 is turned off to stop the motor 5 from rotating. At this time, the user can lie more comfortably on the sofa body 1. When waiting for the sofa body 1 to be used normally, the user can press the forward and reverse switch 4 again to make the output shaft of the motor 5 rotate in the reverse direction, which can drive the first gear 6 and the second gear 7 to rotate counterclockwise. At this time, the armrest 2 will rotate on the sofa body 1 to the initial state under the rotation of the second gear 7, which is convenient for the normal use of the sofa body 1 and also convenient for adjusting the armrest 2 of the sofa body 1, improving the comfort of the user lying on the sofa body 1.

[0037] The dust-proof box 3 is used to cover and protect the motor 5, the first gear 6, the second gear 7 and the rotating shaft 8, preventing the motor 5, the first gear 6, the second gear 7 and the rotating shaft 8 from being exposed and causing these components to be contaminated with dust and affecting the normal working efficiency. When the motor 5 drives the first gear 6 and the second gear 7 to rotate and drives the rotating shaft 8 to rotate, the rotating shaft 8 is fixed to the armrest 2 outside the dust-proof box 3 through the rotating groove 14, so as to protect the adjustment assembly and increase the service life of the adjustment assembly.

[0038] The limiting block 12 rotates within the limiting groove 15 as the rotating shaft 8 rotates, enabling the rotating shaft 8 to be in full contact with the dust-proof box 3. During the rotation of the rotating shaft 8, there will be no significant deviation or vibration that affects the normal rotation efficiency of the rotating groove 14, and the rotating shaft 8 will not separate from the dust-proof box 3. At the same time, the ball 13 will rotate on the limiting block 12 along the inner wall of the limiting groove 15 as the limiting block 12 rotates, which can reduce the frictional force between the limiting block 12 and the dust-proof box 3, thereby improving the rotation efficiency of the rotating shaft 8.

[0039] The turntable 9 rotates as the rotating shaft 8 rotates and rotates along the inner wall of the inner groove. The turntable 9 is restricted within the inner groove and will not shift, making the process of adjusting the angle of the armrest 2 more stable. At the same time, it can provide a certain supporting effect on the armrest 2.

[0040] Several elastic blocks 10 on the turntable 9 rotate as the turntable 9 rotates. As the second gear 7 rotates, the turntable 9 rotates at the same angle as the second gear 7. The second gear 7 and the first gear 6 are meshed tooth by tooth to achieve their rotation. When the second gear 7 rotates to a suitable position as the first gear 6 rotates, the elastic blocks 10 on the turntable 9 will also be engaged in the corresponding card slots 11, further restricting the position of the turntable 9 and providing a certain supporting effect on the turntable 9 to ensure the stability of the rotating shaft 8 and the armrest 2 during rotation.

[0041] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments.
