Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to Figures 1-6, an intelligent sofa that is easy to replace the dust cover, includes a sofa body 1, the sofa body 1 is covered with a dust cover 2, and the bottom of the sofa body 1 is symmetrically provided with a driven gear 3, driven A rotating shaft 4 is fixedly connected to the front of the gear 3, a fixed seat 5 is sleeved on the rotating shaft 4, an eccentric shaft 6 is fixedly connected to the front of the rotating shaft 4, and a driving rod 7 is movably connected to the eccentric shaft 6, and the driving rods 7 are opposite to each other. One end of the sofa is rotatably connected with a first helical tooth plate 8, and a second helical tooth plate 9 is interlaced under the first helical tooth plate 8. The main body 1 is provided with a first movable track 10 corresponding to the first helical tooth plate 8 , and the first movable track 10 is connected with a second movable track 11 corresponding to the second helical tooth plate 9 . The back end and the opposite end of the second helical tooth plate 9 are provided with a buckle groove 12 , the dust cover 2 is provided with a buckle piece 13 corresponding to the buckle groove 12 , and the driven gear 3 is provided between There is a ring gear member 14 meshing with each other. The ring gear member 14 is meshed with a driving gear 15. The ring gear member 14 is sleeved on the left driven gear 3, and is internally provided with the left driven gear 3. There are external teeth meshing with the right driven gear 3. Through the rotation of the ring gear 14, the symmetrical driven gear 3 can be driven to rotate in the opposite direction at the same time, and the drive gear 15 is connected to the There is a conversion device 16. The conversion device 16 includes a conversion gear 161, a driving screw 162, a ratchet 163, a pawl 164, and a check pawl 165. The conversion gear 161 is fixedly connected to the front of the driving gear 15. Below the conversion gear 161, the ratchet 163 is fixedly connected to the left end of the driving screw 162, the pawl 164 is fixedly connected to the driving member 17, and the driving member 17 is a foot pedal. The dust cover 2 can be controlled to be loosened from the sofa or installed and tightened, and an elastic reset assembly 18 is movably connected to the driving member 17. The elastic reset assembly 18 includes an elastic member and a reset seat, and the reset seat is fixedly connected to the sofa body 1. Next, the driving member 17 is movably connected to the reset seat through an elastic member.

Working principle: This smart sofa is easy to replace the dust cover. When replacing the dust cover 2, step on the pedal with your feet, and use the pawl 164 on the pedal to drive the ratchet 163 to operate under the limit of the check pawl 165. One-way rotary motion, the drive screw 162 fixedly connected by the ratchet 163 drives the conversion gear 161 to rotate, so that the ring gear 14 meshing on the drive gear 15 simultaneously drives the driven gear 3 to perform a relative reverse motion, using the driven gear 3 The rotation of the eccentric shaft 6 drives the first helical toothed plate 8 rotatably connected on the driving rod 7 to reciprocate in the direction of the sofa body 1, and at the same time drives the second helical toothed plate 9 interlaced with it to do the same reciprocating motion, when When the engaging grooves 12 provided on the first helical tooth plate 8 and the second helical tooth plate 9 protrude from the sofa body 1, stop stepping on the pedals, and then fasten the corresponding engaging elements 13 on the dust cover 2. In the buckle groove 12, and then continue to step on the pedal, the first helical tooth plate 8 and the second helical tooth plate 9 are used to drive the dust cover 2 connected thereon through the buckle member 13 to cover the sofa, and then retract it. The dust cover 2 is tightly attached to the sofa. When the sofa dust cover 2 needs to be disassembled, it is only necessary to step on the footrests and do the same movement as above, and drive the first helical tooth plate through the eccentric shaft 6. 8 and the second helical plate 9 are in the process of reciprocating movement, according to the position of the buckle groove 12, it is judged to stop or continue to step on the pedal, and when the buckle groove 12 moves to the outside of the sofa body 1, the buckle member 13 The whole process of disassembly and installation is simple and easy to disassemble from the buckle groove 12, and it is not necessary for people to take time and effort to disassemble the dust cover 2 from the sofa, which avoids dust caused by the over-tightening of the dust cover 2 and improper operation. The occurrence of damage to the cover 2 greatly reduces the difficulty of replacing the dust cover 2 and increases the service life of the dust cover 2 .
