[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0021] The embodiment of the present application provides an electric sofa footrest telescopic assembly to solve the problem that people may feel uncomfortable when maintaining the same posture on the sofa for a long time. In addition, people generally have different sitting postures on the sofa, and the required footrest height and angle between the footrest and the calf are also different, so the existing footrest telescopic assembly cannot meet the sitting posture requirements of all people.

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] The embodiment of the utility model discloses a telescopic assembly of an electric sofa footrest.

[0024] According to the attached Figure 1-6 As shown, it includes a telescopic footrest assembly 1, which includes a footrest piece 12 and a telescopic box body 11. The footrest piece 12 includes a long footrest board 121 and a second type telescopic piece 122. An intermediate board 111 and a first type telescopic piece 112 are provided in the telescopic box body 11. The long footrest board 121 is fixedly connected to the top of the second type telescopic piece 122, the second type telescopic piece 122 is fixedly connected to one side of the intermediate board 111, and the first type telescopic piece 112 is fixedly connected to the other side of the intermediate board 111. When in use, the footrest piece 12 gradually rotates outward under the thrust of the intermediate board 111, so that people have more angles of the long footrest 121 to choose from when sitting on it. The larger the angle, the closer to lying flat, so that the user will not feel uncomfortable sitting in one posture on the sofa for too long.

[0025] A cavity 113 is provided in the telescopic box 11, the middle plate 111 is rotatably connected in the cavity 113, a type of telescopic member 112 is fixedly connected in the cavity 113, and sliding arc grooves 114 are provided at both ends of the telescopic box 11. The telescopic box 11 also serves as the base of the sofa, and the long footrest 121 slides in the sliding arc groove 114, which serves as a limit.

[0026] The top ends of the middle plate 111 are fixedly connected with rotating short rods 1111, and the rotating short rods 1111 are rotatably connected to the inner wall of the cavity 113. The side of the middle plate 111 close to the type-one telescopic part 112 is fixedly connected with a supporting long block 1112, and a sliding long groove 1113 is provided in the supporting long block 1112. The middle plate 111 is rotatably connected in the cavity 113. The function of the supporting long block 1112 is to provide a supporting force point for the type-one telescopic part 112.

[0027] A type of telescopic member 112 includes a large cylinder 1121, a clamping block 1122 and a supporting long rod 1123. The clamping block 1122 is fixedly connected to the power output rod of the large cylinder 1121, and the supporting long rod 1123 is fixedly connected in the clamping block 1122. The supporting long rod 1123 is slidingly connected in the sliding long groove 1113. When in use, the large cylinder 1121 sends power through the power output rod, and the power is transmitted to the supporting long block 1112 along with the clamping block 1122 and the supporting long rod 1123 connected to the power output rod. The supporting long block 1112 drives the middle plate 111 to exert force, and finally drives the footrest 12 to slide.

[0028] A soft friction pad 1211 is fixedly connected to the upper end of the footrest board 121 . The soft friction pad 1211 makes people feel more comfortable when putting their feet on the footrest board 121 while preventing friction.

[0029] The second type telescopic component 122 includes a fixed base 1221, a sliding circular component 1222 and a small cylinder 1223. The sliding circular component 1222 is fixedly connected to both sides of the fixed base 1221, the small cylinder 1223 is fixedly connected inside the fixed base 1221, the long footrest plate 121 is fixedly connected to the power output rod of the small cylinder 1223, and the sliding circular component 1222 is slidably connected in the sliding arc groove 114. When in use, the height of the second type telescopic component 122 is adjusted according to the height of the user, so that the electric sofa footrest telescopic component can meet the use of people of different heights.
