[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-Figure 5 , the present invention provides a technical solution: VR-based ergonomics simulation verification system includes: Virtual reality environment creation module: responsible for building virtual work scenes and equipment models, using 3D modeling software to create various realistic environments and equipment, and importing them into the VR system, further enhancing the realism of the virtual environment by adding textures, lighting effects, and physical properties; Human body model building module: used to generate human body models with human anatomical characteristics and kinematic capabilities. The human body model can be customized according to different human body sizes, genders, ages and other factors; Task simulation module: set specific work tasks and operation procedures, and drive the human model to perform tasks in a virtual environment; Ergonomics analysis and evaluation module: conducts a comprehensive ergonomics analysis of human-computer interaction during the simulation process; The virtual reality environment creation module includes VR glasses 1, on which a control button 2 is installed, a cover plate 3 is provided above the button 2, and a sleeve groove 4 adapted to the button 2 is provided at the bottom of the cover plate 3, and a limiter for limiting the position of the cover plate 3 is provided on the VR glasses 1. The cover plate 3 can effectively prevent the control button 2 on the VR glasses 1 from contacting foreign objects. When the VR glasses 1 are stored idle, the cover plate 3 is sleeved on the button 2 through the sleeve groove 4, which prevents the button 2 from being worn, damaged or accidentally touched due to collision, friction, etc., prolongs the service life of the button 2, and also ensures the normal function of the button 2 when the VR glasses 1 are used next time.

[0018] While protecting the button 2, the cover plate 3 does not affect the normal use functions of the VR glasses 1, such as the comfort of the user wearing the VR glasses 1, and does not affect the user's operation of the VR system through the control button 2. This compatibility ensures the normal operation of the VR glasses 1 in the human-machine ergonomics simulation verification system, allowing the user to focus more on the virtual environment and task simulation operations in the system.

[0019] Specifically, Figure 1As shown, the limiting member includes a screw hole 6 provided on the VR glasses 1, the screw hole 6 is connected to the screw rod 8 by a thread, a fixing plate 10 is fixed on the screw rod 8, and the screw rod 8 is slidably connected to a sliding hole 13 provided on the slide plate 12, a clamping block 14 is fixed on the slide plate 12, an opening 5 adapted to the clamping block 14 is provided on the cover plate 3, a corresponding groove 15 corresponding to the opening 5 is also provided on the VR glasses 1, the clamping block 14 penetrates the opening 5 and extends into the corresponding groove 15 provided on the VR glasses 1, and the fixing plate 10 abuts against the upper surface of the slide plate 12, thereby completing the fixation of the cover plate 3 and the VR glasses 1, and a fixing member for fixing the screw rod 8 is provided on the VR glasses 1.

[0020] A spring 9 is sleeved on the screw 8, and one end of the spring 9 abuts against the lower surface of the fixed plate 10, and the other end abuts against the upper surface of the slide plate 12. The elastic force of the spring 9 pushes the slide plate 12 downward until the lower surface of the slide plate 12 abuts against the bend of the cover plate 3. The spring 9 plays a role of automatic adjustment and buffering in the connection structure between the cover plate 3 and the VR glasses 1. When the cover plate 3 is installed, the elastic force of the spring 9 pushes the slide plate 12 downward until the lower surface of the slide plate 12 abuts against the bend of the cover plate 3, so that the cover plate 3 can fit tightly on the VR glasses 1 in the vertical direction, and can also absorb external impact force to a certain extent. For example, when the VR glasses 1 are slightly collided, the spring 9 can buffer this impact force, prevent the cover plate 3 from being damaged due to rigid collision, and further protect the button 2.

[0021] Specifically, Figure 3 As shown, the fixing member includes a screw groove 17 provided on the VR glasses 1, a rotating rod 19 is connected to the screw groove 17 by a thread, and a top block 21 is fixed to the rotating rod 19, a round hole 11 adapted to the top block 21 is provided on the fixed plate 10, and a round plate 20 abutting against the bottom of the fixed plate 10 is fixed on the rotating rod 19.

A rotating block 7 is also fixed on the fixed plate 10, and an adjusting member for assisting the rotating rod 19 in rotating is provided on the VR glasses 1.

[0022] The cover plate 3 and the VR glasses 1 are firmly connected through the limiter and the fixing member. The cooperation between the block 14 in the limiter and the corresponding groove 15, as well as the synergistic effect of the screw 8, the slide plate 12 and other components, ensure the fixation of the cover plate 3 in the horizontal direction; the cooperation between the rotating rod 19, the top block 21 and the circular hole 11 in the fixing member, and the support of the disc 20 to the fixing disc 10 further strengthen the fixation of the cover plate 3 in the vertical direction. This stable connection method prevents the cover plate 3 from loosening or shifting easily on the VR glasses 1, and can maintain the protection state of the button 2 even when subjected to a certain external force impact.

[0023] Specifically, Figure 3As shown, the adjusting member includes a side groove 22 provided on the rotating rod 19, and a plurality of side grooves 22 are distributed at equal angles on the circumference of the rotating rod 19, a side rod 24 is engaged with the side groove 22, and the side rod 24 is fixedly connected with a bent plate 23, and a vertical through hole 25 is provided on the bent plate 23, and a vertical groove 18 corresponding to the through hole 25 is provided on the VR glasses 1, a magnetic rod 26 passes through the through hole 25, and the end of the magnetic rod 26 extends into the vertical groove 18 and is fixed to the vertical groove 18 by magnetic adsorption.

[0024] Specifically, Figure 3 As shown, the VR glasses 1 are provided with a corresponding groove 2 16 that matches the corresponding groove 1 15. After the slide plate 12 is rotated until the block 14 at its bottom is aligned with the corresponding groove 2 16, the block 14 extends into the corresponding groove 2 16 under the elastic force of the spring 9. At this time, when the cover plate 3 moves in the vertical direction, it will not be affected by the slide plate 12.

[0025] In summary, the use process of the upper cover plate 3 of the VR glasses 1 provided in this embodiment is as follows: When the VR glasses 1 are not used for storage, the cover plate 3 needs to be connected to the VR glasses 1. The cover plate 3 can protect the button 2 on the VR glasses 1 and prevent the button 2 from contacting with foreign objects and causing wear and tear. The sleeve groove 4 of the cover plate 3 is sleeved on the button 2, and the bending part of the cover plate 3 is connected to the bottom of the VR glasses 1. Then, the block 14 on the slide plate 12 can pass through the opening 5 opened on the cover plate 3 and extend into the corresponding groove 15 opened on the VR glasses 1, and the sliding hole 13 opened on the slide plate 12 is aligned with the screw hole 6 opened on the VR glasses 1.

[0026] The screw rod 8 is passed through the sliding hole 13, and the screw rod 8 is threadedly connected with the screw groove 17 provided on the VR glasses 1 during rotation until the fixing plate 10 abuts against the slide plate 12. At this time, the position of the slide plate 12 is fixed, and the cover plate 3 and the VR glasses 1 are fixed as a whole.

[0027] Then the rotating rod 19 can be rotated so that the rotating rod 19 moves upward during rotation until the top block 21 fixed on the rotating rod 19 extends into the circular hole 11 opened on the fixed disk 10, and the circular disk 20 fixed on the rotating rod 19 abuts against the bottom of the fixed disk 10.

[0028] The side rod 24 is inserted into the side groove 22 provided on the rotating rod 19, and the bending part of the bent plate 23 fixed on the side rod 24 is slidably connected with the upper surface of the VR glasses 1, and the through hole 25 provided on the bent plate 23 corresponds to the position of the vertical groove 18 provided on the VR glasses 1. Finally, the magnetic rod 26 can be inserted into the vertical groove 18 through the through hole 25. Under the action of the magnetic force, the magnetic rod 26 maintains its position stable, thereby fixing the position of the bent plate 23 and the side rod 24.
