DETAILED DESCRIPTION

[0026] In order to further explain the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the utility model will be described in detail as follows in combination with the drawings and preferred embodiments.

[0027] The technical solutions provided by the embodiments of the utility model will be described in detail in combination with the drawings as follows.

[0028] Referring to Figures 1 to 7 The utility model embodiment provides a sofa armrest supporting multi-person adjustment, is arranged on sofa seat body 1, sofa seat body 1 is configured with several and is arranged side by side, greatly expands the bearing capacity of sofa. Sofa armrest 2 is also configured with several groups and is alternately distributed with several sofa seat bodies 1, and this layout not only ensures that each user can conveniently touch the armrest, but also maintains the overall appearance and coordination of the sofa.

[0029] Each sofa armrest 2 comprises a base 21, an armrest plate 22 and a support 23. The base 21 is mounted at the side end of the corresponding sofa body 1; the armrest plate 22 is transversely arranged above the base 21 (in actual application, a soft pad 26 is mounted at the upper end of the armrest plate 22 to improve the comfort of the user); the support 23 is located between the armrest plate 22 and the base 21, and is driven by power to realize lifting relative to the base 21, and the armrest plate 22 is elastically connected with the support 23. Specifically, the lower end of the armrest plate 22 is provided with at least two longitudinally extending guide columns 221, and the support 23 is provided with guide grooves 232 corresponding to the guide columns 221, the guide columns 221 are slidingly arranged in the corresponding guide grooves 232, the lower end of each guide column 221 is further provided with a limiting plate 222, and a second spring 25 is further sleeved on each guide column 221, and the two ends of the second spring 25 are respectively abutted on the armrest plate 22 and the support 23, so that the limiting plate 222 is abutted on the lower end of the support 23. Therefore, the elastic connection between the armrest plate 22 and the support 23 can be realized under the action of the second spring 25.

[0030] When the user rests his arm on the armrest plate 22, the armrest plate 22 not only changes the height along with the lifting of the support 23, but also makes a slight swing and fine adjustment along with the slight force direction and size of the arm due to the elastic connection.

[0031] In summary, each user can freely adjust the height of the armrest according to his own unique body proportion and sitting posture preference through the power-driven system to find the most suitable support position. The elastic connection between the armrest plate 22 and the support 23 further adapts to the arm movement, and no matter whether the user is lazily leaning on his arm or forcefully supporting it, he can obtain uniform and soft support feedback.

[0032] Multiple sofa bodies 1 arranged side by side are matched with adjustable armrests alternately distributed, which perfectly adapt to the scene of multiple people using at the same time. Especially in the family scene, family members have different heights and body shapes, and everyone can adjust the armrest as needed in real time to avoid mutual accommodation and inconvenience caused by the height of the armrest when sharing the sofa.

[0033] In some actual applications, referring to Figures 2 to 7 Based on the structure of the sofa armrest 2, a locking structure is arranged between the armrest plate 22 and the support 23, and the armrest plate 22 moves relative to the support 23 between a first position and a second position; in the first position, the locking structure is in an unlocked state, and the armrest plate 22 and the support 23 have a gap therebetween; in the second position, the armrest plate 22 is attached to the support 23 and is locked by the locking structure.

[0034] Specifically, the locking structure comprises a lock piece 3 and a movable block 4.

[0035] The lock piece 3 is installed at the lower end of the handrail 22, and the lower end of the lock piece 3 is configured as a sliding end 31, and the lock piece 3 has a first limiting wall 32 thereon;

[0036] The movable blocks 4 are configured in two groups and mirror-imaged in the installation cavities on the support 23, and each of the two movable blocks 4 is provided with an inner chamfer surface 41 at the end close to the other; the two movable blocks 4 are elastically connected with the support 23 to realize elastic contact of the two movable blocks 4; when the handrail 22 is at the second position, the first limiting wall 32 abuts against the lower ends of the two movable blocks 4 to realize limiting of the handrail 22 relative to the support 23 in the moving direction thereof.

[0037] In the embodiment, the handrail 22 can be freely moved between the first position and the second position. The first position in the unlocked state has a spacing between the handrail 22 and the support 23, which provides additional space flexibility for the user. For example, when it is needed to temporarily place some small items such as books and glasses on the handrail, the handrail is switched to the second position to be attached to the support 23 and locked, at which time the handrail returns to the stable support state to support the arm of the user, satisfying different use requirements. The user only needs to apply a simple force to switch the handrail 22 between the two positions, without complex operation procedures, and easily realizes the function switching.

[0038] The lock piece 3 in the locking structure cooperates with the movable blocks 4. The lock piece 3 is installed at the lower end of the handrail 22, and the special sliding end 31 design (such as shown in Figure 3 and Figure 4 , which can be configured as a rounded surface) is matched with the inner chamfer surface 41 of the movable blocks 4, and when the handrail 22 is pressed down to the second position, the inner chamfer surface 41 is used for guidance to smoothly slide the lock piece 3 between the two movable blocks 4; then, the first limiting wall 32 of the lock piece 3 abuts against the lower ends of the movable blocks 4 to achieve a stable limiting effect.

[0039] In some practical applications, as shown in Figures 5 to 7 , each movable block 4 is provided with at least two guide rods 42 at the end away from the inner chamfer surface 41, the two guide rods 42 are slidingly connected in the corresponding guide holes 231 of the support 23, and each guide hole 231 is coaxially installed with a first spring 24, and the first spring 24 elastically abuts against the corresponding guide rod 42.

[0040] The two groups of movable blocks 4 mirror-imaged in the installation cavities of the support 23 are elastically connected with the support 23. Even if used for a long time and frequently, subjected to vibration and external pressure, once the external force disappears, the first spring 24 pushes the movable blocks 4 to quickly reset through the sliding structure of the guide rods 42 in the guide holes 231 to maintain the effectiveness of the locking structure.

[0041] In some practical applications, the two movable blocks 4 are provided with a clearance groove 43 on one side end close to each other (as shown in Figure 5 ), and the mounting cavity penetrates through the left and right side ends of the support 23. Therefore, the user can put his fingers into the clearance groove 43 to push the two movable blocks 4 away from each other, so that the two movable blocks 4 contact the first limiting wall 32 to unlock the connection between the handrail 22 and the support 23.

[0042] Specifically, the two movable blocks 4 are provided with a half-slot hole, and when the two movable blocks 4 abut against each other, the two half-slot holes form a complete hole position 44 (as shown in Figure 5 ), and when the handrail 22 and the support 23 are locked, the lock piece 3 is at least partially located in the hole position 44 to ensure that the remaining part of the two movable blocks 4 can still be elastically abutted together to ensure the limitation of the first limiting wall 32.

[0043] In other practical applications, referring to Figures 1 to 3 , the lower end of the support 23 is provided with at least two longitudinally arranged guide rods 233, each of which is in sliding connection with the base 21, and the lower end of the guide rods 233 is connected with a bottom plate 234; the base 21 is also provided with a linear driving source 27, and the output end of the linear driving source 27 is fixedly connected to the bottom plate 234 to drive the support 23 to ascend and descend; the handrail 22 is also provided with a control panel 28, and the control panel 28 is in electrical connection with the linear driving source 27.

[0044] When the user sits on the sofa and feels that the current height of the handrail is not suitable and needs to be adjusted, the arm is naturally placed on the handrail 22, and the finger easily reaches the control panel 28 installed on the handrail 22 to prepare for adjustment. The user presses or rotates the related button or other operating components on the control panel 28 to send an ascending or descending instruction to the linear driving source 27 in electrical connection therewith. The linear driving source 27 on the base 21 starts to operate after receiving the instruction. Since the output end is fixedly connected to the bottom plate 234, and the bottom plate 234 is connected with the lower end of the at least two longitudinally arranged guide rods 233, the power output by the linear driving source 27 drives the bottom plate 234 to move vertically along the sliding connection structure of the base 21. When the guide rods 233 move upward or downward, the support 23 connected therewith moves synchronously, thereby changing the height of the handrail 22 installed above the support 23 until the user is satisfied with the position, and the whole process is smooth and stable.

[0045] The control panel 28 is arranged on the handrail 22, and a user can easily operate without changing the sitting posture and without greatly moving the arms, so that the convenience of adjustment is greatly improved. The electrical connection ensures instant transmission of instructions, and the linear driving source 27 accurately responds, so that the height of the handrail can be quickly and accurately adjusted to a state conforming to the individual needs of the user.

[0046] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make slight changes or modifications to the above disclosed technical content to obtain equivalent embodiments without departing from the technical solution of the present application. Any modification, equivalent change and modification of the above embodiments made according to the technical essence of the present application still belong to the scope of the technical solution of the present application.
