DETAILED DESCRIPTION

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings, wherein the same components are represented by the same figure numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower", "bottom surface" and "top surface" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Design concept: Design a small, highly adaptable, and adjustable headband-style infrared facial motion capture helmet.

[0031] Example:

[0032] like Figure 1-Figure 4 As shown, the technical solution provided by the utility model is a headband type infrared facial motion capture helmet, including a helmet body 1, a connecting rod 2 and an infrared camera 3, and further including a head circumference adjustment part 4, a sponge lining 5, a tube clamp structure 6 and a positioning ball 7. The two sides of the helmet body 1 are connected to the connecting rod 2 through the tube clamp structure 6, and the infrared camera 3 is arranged in front of the helmet body 1 through the connecting rod 2; a sponge lining 5 is provided on the inner side of the helmet body 1, and a plurality of positioning balls 7 are provided on the outer side, wherein the sponge lining 5 is detachably connected to the helmet body 1, the thickness of the sponge lining 5 is 10 mm, 15 mm or 20 mm, and the connecting rod 2 is a U-shaped aluminum tube.

[0033] The pipe clamp structure 6 of this embodiment includes a pipe clamp 61, a hexagonal bolt 62 and a hand nut 63. The hexagonal bolt 62 passes through the helmet body 1 and is loosely fitted with the pipe clamp 61. The hand nut 63 drives the hexagonal bolt 62 to rotate. The pipe clamp 61 is loosely fitted with the connecting rod 2.

[0034] This embodiment also includes a head circumference adjustment fixing cover 8, and the head circumference adjustment member 4 is clearance-matched with a cylindrical step 81 provided in the head circumference adjustment fixing cover 8, and the head circumference adjustment fixing cover 8 is further fixed to the helmet body 1. The head circumference adjustment member 4 of this product is a head circumference adjustment gear component, which is a ratchet rack structure, which can shorten itself and reduce the distance with the helmet body 1 to achieve helmet stability. The previous helmets used a hat-type structure to fit the user's head, while this product uses a headband-type structure to lock the user's head.

[0035] The infrared camera 3 of this embodiment has a circular groove 31 , a hand-tightening bolt 32 and a nut 33 at the bottom. The hand-tightening bolt 32 passes through the circular groove 31 and is threadedly connected with the nut 33 . The circular groove 31 and the connecting rod 2 are clearance-fitted.

[0036] In this embodiment, ear plates 9 are provided on both sides of the helmet body 1. During actual use, it is found that the previous helmets were stressed at the temples. Now, this product innovatively adds ear plates 9 to relieve the stress on the temples and change it to the cheekbones.

[0037] The positioning balls 7 of this embodiment are fixed to the helmet body 1 by means of hexagon socket set screws 10 , and the positioning balls 7 are respectively arranged on both sides of the helmet body 1 , the top of the head and the forehead.

[0038] This product achieves adaptation to a wide range of head shapes by adding a head circumference adjustment piece 4 and sponge liners 5 of different thicknesses; the infrared camera 3 is adjusted at a distance from the user's face by a tube clamp structure 6, and the infrared camera 3 can be quickly removed; the overall structure of this product is achieved through the form of a headband and the coordination of the head circumference adjustment piece 4 to achieve a tight fit between the helmet and the user's head, unlocking the use scenario of intense exercise, and cooperating with the user's cheekbones on the main structural parts to improve the comfort of product use.

[0039] Working principle:

[0040] Through holes are opened on both sides of the helmet body 1 of this product. The hexagonal bolts 62 pass through the through holes and are loosely matched with the pipe clamp 61, and are fixed by hand nuts 63. The pipe clamp 61 is loosely matched with the connecting rod 2. The connecting rod 2 can be axially adjusted forward and backward in the hole of the pipe clamp 61 to adjust the distance between the camera and the face. When the hand nuts 63 are rotated, the pipe clamp 61 is clamped, and the connecting rod 2 and the pipe clamp 61 are tightly matched and cannot be moved.

[0041] The head circumference adjustment part 4 (i.e., the head circumference adjustment gear) is clearance-matched with the cylindrical step 81 provided on the surface of the head circumference adjustment fixing cover 8, and the head circumference adjustment fixing cover 8, the head circumference adjustment part 4 and the helmet body 1 are locked by screws. Specifically, when the gear inside the head circumference adjustment gear is rotated, the head circumference adjustment gear as a whole will be shortened, thereby shortening the overall distance between the helmet body 1 and the head circumference adjustment gear, and finally achieving the effect of tightening the head circumference.

[0042] The sponge lining 5 of this embodiment has different thicknesses of 10mm, 15mm, and 20mm corresponding to different head shapes, and the sponge lining 5 is connected to the helmet body 1 by Velcro. A circular groove 31 and a through hole are provided at the bottom of the infrared camera 3 component, and the circular groove 31 and the connecting rod 2 are clearance-matched, and the camera angle is adjustable. The hand screw bolt 32 passes through the through hole and is threadedly matched with the nut 33. When the hand screw bolt 32 is rotated, the infrared camera 3 component and the connecting rod 2 are tightly matched and cannot be moved.

[0043] Ear plates 9 are provided on both sides of the helmet body 1. When the user wears it, the ear plates 9 are located at the cheekbones of the user's head. Through the cooperation between the cheekbones and the ear plates 9, the problem of temple pain when the user wears the helmet is solved, and the wearing comfort is improved.

[0044] The surface of the helmet body 1 is provided with a threaded hole which is threadedly matched with the hexagon socket set screw 10, and the surface of the positioning ball 7 is provided with the same threaded hole which is threadedly matched with the hexagon socket set screw 10, so that the positioning ball 7 is installed on the surface of the helmet body 1. The position of the positioning ball 7 on the surface of the helmet body 1 is set by the user, and its role is to assist the computer in the later capture processing and provide a spatial positioning point.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
