[0016] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiment of the utility model is explained in detail below. In the following description, a lot of specific details are set forth in order to fully understand the utility model. However, the utility model can be implemented in many other ways different from the description, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the following disclosed specific embodiments.

[0017] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] like Figs. 1-4 As shown, an adjustable interpupillary distance (IPD) and diopter FPV glasses includes a front shell 1, a rear shell 2, a main board 3, a support 4, optical modules 5, and an antenna 6. The front shell 1 and rear shell 2 are detachably connected to the front and rear ends of the support 4, respectively. The main board 3 is mounted on the support 4 and electrically connected to the optical modules 5. A slide bar 41 is provided inside the support 4, and two sets of optical modules 5 are mounted side-by-side inside the support 4 via the slide bar 41. The distance between the two sets of optical modules 5 is adjustable. The antenna 6 is mounted on the outer wall of the front shell 1 and is foldable. Specifically, in this embodiment, the front shell 1, rear shell 2, and support 4 are all injection molded from plastic and connected by bolts. The main board 3 is provided inside the support 4 to control the optical modules 5. Simultaneously, two sliding rods 41 are installed inside the bracket 4, arranged side by side, for movable connection with the upper end of the optical module 5. This ensures the stability of the two optical modules 5, preventing them from rotating around the sliding rods 41. The sliding rods 41 also serve as guides, allowing users to manually or automatically adjust the distance between the two optical modules 5, thereby adjusting the interpupillary distance to suit users with different interpupillary distances. Furthermore, the optical module 5 integrates diopter adjustment to accommodate users with different vision. To prevent antenna breakage and poor contact, the two antennas 6 are directly integrated into the front shell 1, eliminating the need for connectors and reducing additional parts. When using the FPV glasses, the antennas 6 are opened to a vertical position, providing excellent reception of image transmission signals. The integrated design prevents disconnection, ensuring the signal won't be lost suddenly during flight due to antenna 6 issues. The foldable antennas also facilitate storage.

[0020] like Figs. 2-4As shown, the optical module 5 comprises a lens barrel 51, a lens group 52 and an adjusting knob 53, the lens barrel 51 is movably connected with the slide rod 41, the lens group 52 is installed in the lens barrel 51, and the adjusting knob 53 is installed outside the lens barrel 51, which is used to adjust the diopter of the lens group 52. Specifically, the lens group 52 is arranged in the lens barrel 51, which is known to comprise an ocular lens and an image-forming lens, which is a prior art and will not be described by the applicant. The specific improvement is that we install the adjusting knob 53 for adjusting the interpupillary distance and the diopter below the lens barrel 51 and extend it out of the front shell 1, which is convenient for the user to operate. When adjusting the interpupillary distance, the user only needs to pinch the adjusting knob 53, which can drive the two optical modules 5 to move closer or farther away along the direction of the slide rod 41 to adapt to users with different interpupillary distances. When adjusting the diopter, the user needs to rotate the adjusting knob 53 to adjust the lens of the lens group 52, specifically, the distance between the lens and the ocular lens can be changed to adjust the diopter, or the lens can be deformed to change the diopter, which is a prior art and will not be described.

[0021] As shown in Figs. 2-4 The upper end of the lens barrel 51 is provided with a sleeve 511, and the slide rod 41 movably penetrates the sleeve 511. Specifically, the sleeve 511 is arranged on the lens barrel 51, and the slide rod 41 directly penetrates the sleeve 511 during assembly, which is extremely convenient to assemble.

[0022] As shown in Figs. 3-4As shown, the adjusting knob 53 comprises a knob 531, a rotating rod 532, a spring 533, a seat 534 and a clamping joint 535, the clamping joint 535 is connected with the lower end of the rotating rod 532, the upper end of the rotating rod 532 is connected with the lens barrel 51 through the seat 534, the knob 531 is movably sleeved on the clamping joint 535, the edge of the clamping joint 535 is provided with a notch 5351, the knob 531 is provided with a stop block 5311 corresponding to the notch 5351, the spring 533 is sleeved on the rotating rod 532, one end of the spring 533 abuts against the seat 534, and the other end of the spring 533 abuts against the knob 531. Specifically, in use, the user can drive the rotating rod 532 to rotate through the knob 531, when the rotating rod 532 rotates, a certain lens in the lens group 52 in the lens barrel 51 can be driven to displace forward and backward, that is, the focal length between the lens and the pupil of the user is adjusted. For myopic users, the adjusting knob 53 can make the lens in the lens group 52 move forward to reduce the refraction ability of light, so that the image is focused on the retina. For hyperopic users, the adjusting knob can make the lens move backward to increase the refraction ability of light, so that the image is also focused on the retina. Such technology is prior art and will not be described here. The most important point of the adjusting knob 53 designed by us is that it has a self-locking function, that is, it prevents the user from accidentally touching the knob 531 to change the focal length. When the user adjusts the focal length, the user presses the knob 531, so that the spring 533 resets from the stretched state. At this time, the user rotates the knob 531 at a small angle, so that the stop block 5311 in the knob 531 just engages with the notch 5351 at the edge of the clamping joint 535. At this time, the knob 531 cannot continue to rotate. When the user needs to pull the knob 531 outward, the spring 533 does work, so that the stop block 5311 exits from the notch 5351, and the knob 531 can continue to rotate to adjust the focal length to adapt to users with different vision.

[0023] As shown in the figure, Figs. 1-2 As shown, the antenna 6 is movably connected with the front shell 1 through a pin shaft. Specifically, the outer shell of the antenna 6 is designed in an integrated manner with the front shell 1, reducing additional components, and the inner part has an antenna body that saves signals. Because it is directly connected movably through a pin shaft, the antenna 6 can be folded horizontally back to the FPV glasses when use is completed. It will not be damaged by falling to the ground, so the antenna 6 can be folded, stable and not easy to be damaged.

[0024] As shown in the figure, Figs. 1-2 As shown, the rear shell 2 is provided with a mask 21 on the side away from the support 4. When worn, it is in flexible contact with the face of the user, and the wearing experience is better. Specifically, the mask 21 is made of sponge.

[0025] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
