DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0016] Embodiment: As Figures 1-3 shown, the present utility model provides a head-mounted display device bracket, which includes a headband 1. The headband 1 is made of elastic nylon material. One end of the headband 1 is fixedly installed with a forehead guard 2. One end of the forehead guard 2 is movably installed with a connection mechanism 3. One end of the connection mechanism 3 is fixedly connected with a clamping device 4. The clamping device 4 includes an upper bottom plate 41. Three sliding grooves 42 are opened inside one side of the upper bottom plate 41. Three sliders 43 are slidably connected to the outer surfaces of the three sliding grooves 42. One end of each of the two sliders 43 located on both sides is fixedly connected with a guide rod 44. One end of the slider 43 located in the middle is rotatably connected with a threaded rod 45. One end of the threaded rod 45 threadedly penetrates the upper bottom plate 41 and is rotatably sleeved with a clamping plate 48. One end of the two guide rods 44 penetrates the upper bottom plate 41 and is fixedly connected with one end of the clamping plate 48 together. The bottom end of the upper bottom plate 41 is fixedly connected with a lower bottom plate 49. An operator can realize the threaded movement of the clamping plate 48 by rotating the runner at one end of the upper bottom plate 41 under the rotation of the threaded rod 45. The two guide rods 44 on both sides help the threaded rod 45 to be more stable during the movement process. The three sliders 43 provide a certain distance limit for the movement of the clamping plate 48 while ensuring the stable movement of the two sliding grooves 42 and the threaded rod 45. The movement process of clamping and fixing the display device is realized under the horizontal movement of the clamping plate 48.

[0017] The connecting mechanism 3 includes two extension rods 31. One end of each of the two extension rods 31 is rotatably connected to one end of the forehead guard 2. A second screw rod 37 is threadedly inserted through one end of each of the two extension rods 31. The second screw rod 37 penetrates through one end of the forehead guard 2. One end of the second screw rod 37 is fixedly connected to a second knob 38. A connecting pin 35 is inserted through one end of the upper bottom plate 41. One side outer surface of the connecting pin 35 is rotatably connected to a damping rotating shaft 34. One end of the damping rotating shaft 34 is rotatably connected to one end of each of the two extension rods 31 together. A first screw rod 32 is threadedly inserted through one end of each of the two extension rods 31. The first screw rod 32 penetrates through one end of the damping rotating shaft 34 and is threadedly sleeved with one end of one of the extension rods 31. One end of the first screw rod 32 is fixedly connected to a first knob 33. The connection and installation of both ends of the extension rod 31 can be realized by rotating the first screw rod 32 and the second screw rod 37. One end of the extension rod 31 is connected to the damping rotating shaft 34 through the first screw rod 32. The damping rotating shaft 34 is connected to the upper bottom plate 41 through the connecting pin 35 at one end, realizing the three-stage connection process of the clamping device 4 and the forehead guard 2, facilitating the operator to separate and disassemble the clamping device 4 and the forehead guard 2, and having a certain degree of mobility and extensibility.

[0018] Clamping gaskets 46 are fixedly connected to the inner walls of one side of the upper bottom plate 41 and the inner wall of one side of the clamping plate 48. An anti-slip rubber pad 47 is fixedly installed at one end of the upper bottom plate 41. The two clamping gaskets 46 and the anti-slip rubber pad 47 are to increase the friction during the clamping process of the display device, improve the stability of the display device, and prevent the display device from causing damage to the outside when subjected to the clamping force.

[0019] The lengths of the three sliding grooves 42 are the same, and the outer surfaces of the three sliding grooves 42 are slidably fitted with the outer surfaces of the three sliders 43. The size of the clamping plate 48 is the same as the size of one end of the upper bottom plate 41. The two guide rods 44 are mirror-symmetrically distributed. The upper bottom plate 41, the clamping plate 48, and the lower bottom plate 49 together form a "T" shape. The three sliding grooves 42 provide a stable and equal moving distance for the three sliders 43, ensuring the stable movement of the threaded rod 45 and the two guide rods 44. The clamping plate 48 and the upper bottom plate 41 with the same size are for the convenience of the display device to be clamped and fixed on both sides by the movement of the clamping plate 48. The two mirror-symmetric guide rods 44 help the clamping plate 48 to be more stable during the movement, avoiding the phenomenon of unstable clamping caused by the inclination of the clamping plate 48. The purpose of forming a "T" shape is to facilitate the stable clamping and fixing of the three end faces of the display device, providing rationality for realizing the support and fixation of the display device.

[0020] Working principle: When it is necessary to fix the display device, the operator rotates the runner at one end of the clamping plate 48, driving the threaded rod 45 to rotate between a chute 42 in the middle of the upper base plate 41. A threaded groove for cooperating with the threaded rod 45 is provided on the inner wall of one side of the upper base plate 41. Driven by the threaded rod 45 moving in a threaded manner, the clamping plate 48 moves horizontally to one side. The two guide rods 44 help the clamping plate 48 not to deviate during the movement, providing a stable horizontal movement guide for the movement of the clamping plate 48. The three sliders 43 respectively ensure the stable movement and limit of the two guide rods 44 and the threaded rod 45 between the chutes 42. When the distance between the clamping plate 48 and one end of the upper base plate 41 is sufficient, the display device is placed at one end of the upper base plate 41 and the lower base plate 49, so that the display device is clamped to one end of the upper base plate 41 and the lower base plate 49. Then, the runner is rotated again so that the clamping plate 48 continuously clamps and fixes one side of the display device, thereby realizing the clamping and fixing of the display device;

[0021] When it is necessary to install the display device, align one end of the two extension rods 31 with one end of the forehead guard 2. Then, rotate one end of the second screw rod 37 through one end of the two extension rods 31 and the forehead guard 2 by rotating the second knob 38 to fix one end of the two extension rods 31. Align the other end of the extension rod 31 with one end of the damping rotating shaft 34. Rotate the first knob 33 to penetrate one end of the first screw rod 32 through the damping rotating shaft 34 and socket-fix it with one of the extension rods 31 to complete the connection and fixation of both ends of the extension rod 31. Then, connect and fix one end of the upper base plate 41 through the connection pin 35 between the damping rotating shafts 34 to complete the installation process. The operator can realize the rotation action of the display device by rotating the damping rotating shaft 34.

[0022] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model also intends to include these modifications and variations.
