[0002] Currently, some controllable deformable human models can be seen on the market, which can be deformed and adjusted according to the height and weight of the person trying on clothes. Chinese patent CN115533926A discloses a segmented fitting robot, which is surrounded by a number of membranes to form a human body shape, and a layer of elastically extensible and shrinkable fabric cover is placed on the outer cover of the fitting robot; each membrane includes a hard membrane body and a flexible and deformable matching part, and the matching part is arranged around the outer edge of the membrane body; when the membrane body moves to adapt to the human body shape, the matching part also moves accordingly, and at the same time, the edge of the matching part will bend inward due to the pressure of the fabric cover, so that the edges of adjacent membranes are more rounded and smoothly connected to simulate the smooth surface of human skin.

[0003] Chinese patent CN216883991U discloses a shoulder adjustment mechanism for a fitting robot, in which a diaphragm is provided on the shoulder of the robot, and the shoulder width of the robot is adjusted by moving the diaphragm left and right. However, when the shoulder width of the robot is large, the distance that the shoulder diaphragm moves outward is too large, which will cause a large gap between the inner end of the shoulder diaphragm and the bottom end of the neck diaphragm; because a layer of fabric cover is covered on the outer surface of the robot, the fabric cover will form obvious depressions and wrinkles at the gap, which not only makes it difficult for the robot to meet ergonomics to achieve fitting effectiveness, but also affects the appearance of the robot. Utility Model Content

[0004] In view of this, the utility model proposes a shoulder structure of a fitting robot, which is used to solve the problem that there is a large gap between the inner end of the shoulder diaphragm and the bottom end of the neck diaphragm of the current fitting robot.

[0024] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, a shoulder structure of a fitting robot of the utility model comprises a main frame 1, a neck tube 2 and a diaphragm 3.

[0026] Among them, the main frame 1 is a frame structure located inside the fitting robot and plays a main supporting role. The main frame 1 will be installed with various driving components and transmission components, and the neck tube 2 and the diaphragm 3 are correspondingly installed on the driving components or transmission components.

[0027] The neck 2 is mounted on the main frame 1 and simulates the neck of a robot.

[0028] The diaphragm 3 is arranged on the main frame 1 and located at the shoulders of the robot, with one diaphragm 3 on each shoulder. The diaphragm 3 can be horizontal or have a certain inclination angle to simulate the inclination of the human shoulder. The diaphragm 3 in the current fitting robot is relatively short, and there is a certain gap between the inner end of the diaphragm 3 and the bottom end of the neck tube 2. Therefore, when the diaphragm 3 moves outward to simulate a larger shoulder width, the gap distance between the inner end of the diaphragm 3 and the bottom end of the neck tube 2 will increase significantly. In order to solve this problem, the present embodiment adopts a diaphragm 3 with an increased length, so that the end of the diaphragm 3 facing the neck tube 2 is extended to the bottom of the neck tube 2, which can be regarded as hiding a part of the diaphragm 3 under the neck tube 2, and making the end of the neck tube 2 facing the diaphragm 3 overlap on the outer surface of the diaphragm 3, and there is still a small gap between the bottom end of the neck tube 2 and the outer surface of the diaphragm 3, so that the diaphragm 3 will not rub against the bottom of the neck tube 2 when moving; when the diaphragm 3 moves relative to the neck tube 2 and the length of the part of the diaphragm 3 located under the neck tube 2 is adjusted, the part of the diaphragm 3 hidden under the neck tube 2 will move to the outside, but the end of the neck tube 2 facing the diaphragm 3 is still overlapped on the outer surface of the diaphragm 3, thereby avoiding the formation of a large gap between the adjacent edges of the neck tube 2 and the diaphragm 3.

[0029] exist Figure 2 In a preferred embodiment shown, a driving mechanism 4 is further included to enable the diaphragm 3 to move to simulate the change of shoulder width.

[0030] The driving mechanism 4 is arranged on the main frame 1 , and the driving mechanism 4 drives the diaphragm 3 to move relative to the neck tube 2 , and changes the length of the portion of the diaphragm 3 located directly below the neck tube 2 .

[0031] exist Figure 2 In a preferred embodiment shown, in order to guide the moving direction of the diaphragm 3, a first movable block 5, a second movable block 6 and a guide member 7 are also included.

[0032] The driving mechanism 4 is arranged at an end of the diaphragm 3 away from the neck tube 2 .

[0033] The first movable block 5 is arranged on the driving end of the driving mechanism 4 and moves horizontally along the shoulder width direction of the robot under the drive of the driving mechanism 4. The first movable block 5 is fixedly connected to the inner surface of the end of the diaphragm 3 away from the neck tube 2 and drives the diaphragm 3 to move synchronously.

[0034] One end of the guide member 7 is arranged on the main frame 1 and is located directly below the neck tube 2 , and the other end of the guide member 7 extends toward the first movable block 5 along the shoulder width direction of the robot.

[0035] The second movable block 6 is disposed on the guide member 7 and moves along the extending direction of the guide member 7 . The second movable block 6 is fixedly connected to the inner surface of the diaphragm 3 facing one end of the neck tube 2 and moves synchronously with the diaphragm 3 .

[0036] When the above technical solution is adopted, when the shoulder width needs to be increased, the driving mechanism 4 drives the first movable block 5 to move outward, the first movable block 5 pulls the outer end of the diaphragm 2 to make the diaphragm 2 move synchronously, the diaphragm 2 pulls the second movable block 6 to move synchronously, and the second movable block 6 limits the moving direction of the diaphragm 2 under the guidance of the guide member 7.

[0037] exist Figure 2 In a preferred embodiment shown, in order to limit the movement range of the diaphragm 3, a pulley mechanism 8 is also included.

[0038] The guide member 7 is provided with a slide groove 701 along its extending direction. Both ends of the slide groove 701 are closed, thus limiting the movement range of the diaphragm 3 from being too large.

[0039] The pulley mechanism 8 is arranged in the slide groove 701 and moves along the slide groove 701, and the second movable block 6 is arranged on the pulley mechanism 8. The pulley mechanism 8 can make the movement of the second movable block 6 smoother and the friction resistance smaller.

[0040] exist Figure 3 In a preferred embodiment shown, in order to simulate the inclination of a human shoulder, the distance between the second movable block 6 and the ground is greater than the distance between the first movable block 5 and the ground.

[0041] exist Figure 3 In a preferred embodiment shown, due to the inclination of the human shoulder, the diaphragm 2 does not move horizontally but moves along the inclination angle of the robot shoulder, so the moving direction of the first movable block 5 intersects with the moving direction of the second movable block 6.

[0042] exist Figure 3 In a preferred embodiment shown, in order to enable the diaphragm 3 to simulate the inclination angle of the human shoulder and still effectively adjust the shoulder width, the end of the guide member 7 facing the neck tube 2 is hinged to the main frame 1, so that the free end of the guide member 7 rotates around the hinged part relative to the main frame 1, and adjusts the intersection angle of the moving direction of the first movable block 5 and the moving direction of the second movable block 6, thereby achieving the adjustment of the shoulder inclination angle; the first movable block 5 is hinged to the driving end of the driving mechanism 4, so as not to hinder the movement of the diaphragm 2.

[0043] exist Figure 2In a preferred embodiment shown, the driving mechanism 4 is a linear telescopic mechanism.

[0044] exist Figure 1 In a preferred embodiment shown, the neck 2 comprises two flaps 21 .

[0045] The membrane petals 21 are semi-cylindrical, and the two membrane petals 21 are symmetrically arranged on the main frame 1 to form a neck tube 2 . The ends of the membrane petals 21 facing the membrane sheet 3 overlap the outer surface of the membrane sheet 3 .

[0046] exist Figure 1 In a preferred embodiment shown, in order to simulate the change in thickness of the human neck to match the change in shoulder width of the human body, the membrane flap 21 moves relative to the main frame 1 along the shoulder width direction of the robot, and the two membrane flaps 21 move in opposite directions at the same time and adjust the radial length of the neck tube 2.
