[0069] Example 1

[0070] This embodiment provides a head mounted display device 1, referring to Figure 1 , Figure 2 , Figure 3 , which includes:

[0071] Cylindrical body 2;

[0072] Display 3; the display 3 is arranged at one end inside the cylindrical body 2, and is used to display image information and / or text information;

[0073] The lens 4 is connected to the other end of the cylindrical body 2 and is used to transmit the information displayed on the display 3;

[0074] Observation board 5; the observation board 5 and the display 3 are respectively arranged at two ends of the lens 4, and the observation board 5 is used to present the information transmitted by the display 3 through the lens 4;

[0075] A base 6 and a headgear 7; the base 6 is used to connect the cylindrical body 2 and the headgear 7.

[0076] Example 2

[0077] Example 2 is set on the basis of Example 1, referring to Figure 3 As an optional embodiment, the cylindrical body 2 further includes a sealing bottom cover 21; wherein:

[0078] The sealing bottom cover 21 is snap-fitted to one end of the cylindrical body 2 to form a sealed cavity inside the cylindrical body 2 to prevent external contamination.

[0079] Since the head-mounted display device 1 is mostly used in company construction operations, it is inevitable to encounter pollutant particles such as dust. In order to prevent the display 3 inside the cylindrical body 2 and the side of the lens 4 facing the display 3 from being contaminated with dust and thus affecting the imaging quality, a sealed bottom cover 21 is provided to prevent pollutant particles from entering the cylindrical body 2 from the bottom.

[0080] Example 3

[0081] Example 2 is set on the basis of Example 1, referring to Figure 4 As an optional implementation, the lens 4 includes a lens sheet 42 and a lens connector 41; wherein:

[0082] The lens sheet 42 is engaged and connected with the lens connecting member 41;

[0083] The lens connector 41 is connected to the other end of the cylindrical body 2 via a thread, and the distance between the display 3 and the lens sheet 42 can be adjusted by rotating the thread to ensure clear display information.

[0084] As the usage time increases, the lens piece 42 will inevitably be worn, scratched, etc., so the lens connector 41 is set to a threaded connection. On the one hand, it is convenient to replace the lens 4 as a whole; on the other hand, since different lens pieces 42 must have different optical parameters, the threaded connection can also facilitate the adjustment of the distance between the lens piece 42 and the display 3, ensuring that clear information can be presented in the end.

[0085] Example 4

[0086] Example 4 is set on the basis of Example 1, referring to Figure 5 , Figure 6 , Figure 7 As an optional embodiment, the cylindrical body 2 includes a clamping member 22 and a fixing member 23; wherein:

[0087] The clamping member 22 is disposed at the end of the cylindrical body 2, and the clamping member 22 further includes a concave array surface 221;

[0088] The base 6 includes a through hole 61 , and the fixing member 23 fixes the base 6 and the clamping member 22 through the through hole 61 , and the end of the fixing member 23 is adapted to be clamped with the groove 222 in the concave array surface 221 .

[0089] In actual use, the cylindrical body 2 and the base 6 need to be connected as firmly as possible, otherwise even a slight looseness will cause blurred information transmission. Based on this premise, a screw can be used as a fixing member 23, and directly inserted into the groove 222 in the concave array surface 221 through the through hole 61 on the base 6, so that the end of the screw can be firmly fixed in the groove 222, making it difficult for the screw to loosen or slide.

[0090] More importantly, different operators have different observation habits for the information displayed on the observation panel 5 when using the head mounted display device 1, and the appropriate observation position of the previous operator may not be suitable for the next operator. Therefore, in order to facilitate the adjustment of the cylindrical body 2 and the base 6 in different directions, the concave array surface 221 is covered with grooves 222 so that the screws can be fixed in any direction.

[0091] Example 5

[0092] Example 5 is set on the basis of Example 1, referring to Figure 8 As an optional embodiment, the cylindrical body 2 includes a pull rod 24 and a positioning portion 25; wherein:

[0093] One end of the pull rod 24 is connected to the observation plate 5;

[0094] The other end of the pull rod 24 is slidably connected to the positioning portion 25 to adjust the distance between the observation plate 5 and the lens 4 .

[0095] When the imaging information on the observation plate 5 is blurred, the distance between the observation plate 5 and the lens 4 can be adjusted by sliding the pull rod 24 so that the observation plate is in a comfortable position for the eyes to observe.

[0096] As an optional implementation, refer to Fig. 9 , Fig.10 , Fig.11 , Fig.12 , the cylindrical body 2 includes a clamping portion 26; the clamping portion 26 also includes a clamping fixing groove 261, a first elastic clamping groove 262 and a second elastic clamping groove 263; wherein:

[0097] The clamping and fixing groove 261 is adapted to be clamped with the pull rod 24 to fix the relative position of the clamping portion 26 and the pull rod 24;

[0098] The opening of the first elastic clamping groove 262 gradually decreases from the inside to the outside to achieve self-clamping of the pull rod 24;

[0099] The opening of the second elastic clamping groove 263 gradually decreases from the inside to the outside to achieve self-clamping of the observation plate 5.

[0100] The first elastic clamping groove 262 and the second elastic clamping groove 263 can be prepared by selecting elastic rubber material. Rubber has excellent elasticity and toughness, and is widely available and low in cost.

[0101] As an optional implementation, refer to Fig.13 The other end of the pull rod 24 is rotatably connected to the observation plate 5 through the clamping portion 26 to achieve arbitrary adjustment of the observation plate 5 and the visual angle.

[0102] When taking a break between operations, the operator usually does not need to check the information transmitted on the observation plate 5 all the time. At this time, the observation plate 5 can be flipped upward to avoid blocking the field of vision.

[0103] Example 6

[0104] Example 6 is set on the basis of Example 1, referring to Fig.14 , Fig.15 As an optional embodiment, the bottom 6 includes a mounting groove 62, a clamping through hole 63 and a clamping column 64; wherein:

[0105] The mounting groove 62 is used to fit and snap-fit ​​the headgear 7 (such as a safety helmet, the mounting groove 62 can fit and snap-fit ​​with the brim of the safety helmet);

[0106] The pressing column 64 passes through the pressing through hole 63 to press the headgear 7 .

[0107] In actual operation, the cylindrical body 2 needs to be installed on the headgear 7 (such as a helmet) through the base 6 as firmly as possible, so the above-mentioned clamping and pressing methods act simultaneously to better ensure the reliability of the installation.

[0108] As an optional implementation, refer to Fig.15 , the headgear 7 comprises a left groove 71 and a right groove 72; wherein:

[0109] When the left groove 71 is engaged with the mounting groove 62, the head mounted display device 1 is used for left eye observation;

[0110] When the right groove 72 is engaged with the mounting groove 62 , the head mounted display device 1 is used for right eye observation.

[0111] Different operators often have different observation habits (some are used to observing with their left eye, while others are used to observing with their right eye). Such a setting can meet the observation needs of different groups of people and facilitate the promotion of the product.

[0112] Example 7

[0113] Example 7 is set on the basis of Example 1, referring to Fig.16 The observation plate 5 is made of a transparent material (such as glass, transparent resin, etc.) and includes a front surface 51 and a back surface 52; wherein:

[0114] The front surface 51 is attached with a reflection enhancement film for enhancing the display of transmitted information;

[0115] The back surface 52 is affixed with a transmission attenuation film to reduce the interference of external light on operators observing transmission information.

[0116] With this arrangement, when the external light is too strong, operators can still observe clearer information.

[0117] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
