Description

Technical Field

[0001] This application relates to the field of display device technology, and more particularly to a head-mounted display device and a drone system. Background Technology

[0002] In related technologies, head-mounted display devices used with drones are generally fixed to the wearer's head via a headband.

[0003] However, the headband material is generally relatively soft. During the wearing of a head-mounted display device, the headband is prone to sagging downwards and pressing on the wearer's ears. The head-mounted display device is also prone to pressing on the wearer's cheekbone due to tilting. Therefore, the wearing comfort of head-mounted display devices in related technologies is poor. Utility Model Content

[0004] In view of this, embodiments of this application aim to provide a head-mounted display device and a drone system that can improve wearing comfort.

[0005] This application provides a head-mounted display device, including:

[0006] The glasses themselves;

[0007] Headband;

[0008] An adapter is used to connect the glasses body and the headband, wherein one end of the adapter is connected to the glasses body at a first position, and the other end of the adapter is connected to the headband at a second position, and the height difference between the second position and the first position in the direction of gravity is greater than 0.

[0009] In some embodiments, the headband has a back-head stress point, and the height difference between the back-head stress point and the center of gravity of the glasses body along the direction of gravity is greater than 0.

[0010] In some embodiments, the adapter has a plurality of selectable second positions, each second position forming a height difference along the direction of gravity.

[0011] In some embodiments, each of the second positions is spaced apart along a longitudinal direction, the longitudinal direction being perpendicular to the direction of gravity.

[0012] In some embodiments, one end of the adapter is detachably connected to the eyeglasses body, and / or the other end of the adapter is fixedly connected to the headband.

[0013] In some embodiments, the glasses body is provided with a connection port, and one end of the adapter is provided with a mounting part, which passes through the connection port and is connected to the connection port at the first position.

[0014] In some embodiments, the head-mounted display device includes a dorsolateral head support pad disposed on the headband, and / or,

[0015] The headband includes an extension for adjusting the length of the headband.

[0016] In some embodiments, the head-mounted display device includes at least one of a forehead support and a cheekbone support.

[0017] In some embodiments, the glasses body includes a support body and a display screen disposed on the support body, and the head-mounted display device includes a light shield with a clearance opening disposed on the support body, and the clearance opening avoiding the display screen;

[0018] The head-mounted display device includes a forehead support member disposed on the light shield; and / or,

[0019] The head-mounted display device includes a cheekbone support member disposed on the light shield.

[0020] Another embodiment of this application provides an unmanned aerial vehicle (UAV) system, including a UAV and the aforementioned head-mounted display device, wherein the head-mounted display device is signal-connected to the UAV.

[0021] This application provides a head-mounted display device and a drone system. The headband and glasses of the head-mounted display device are connected by an adapter. One end of the adapter is connected to the glasses at a first position, and the other end is connected to the headband at a second position. The height difference between the second and first positions in the direction of gravity is greater than zero. Because the adapter acts as a rigid connection between the headband and the glasses, the height difference between the second and first positions in the direction of gravity does not cause the glasses to deviate from the wearer's eyes. Since the height difference between the second and first positions in the direction of gravity is greater than zero, the headband is actually offset upwards away from the wearer's ears. The point of force application on the wearer's head is also correspondingly offset upwards and backwards. This not only effectively prevents the headband from collapsing downwards and pressing on the wearer's ears, but also allows the glasses to remain stably positioned on the wearer's face, with minimal risk of pressure on the wearer's cheekbones due to tilting, thus effectively improving the wearing comfort of the head-mounted display device.

[0022] Other technical effects of this application are described in detail in the specific embodiments. Attached Figure Description

[0030] This application provides a head-mounted display device. Please refer to [link / reference]. Figures 1 to 3 The head-mounted display device includes glasses body 10, headband 20 and adapter 30.

[0031] Please see Figure 2 and Figure 3 The glasses body 10 includes a support body 11 and a display screen 12 disposed on the support body 11. The display screen 12 is used to display electronic information such as images and text.

[0032] In some embodiments, please refer to Figures 1 to 3 The head-mounted display device may also include a light shield 40 with a clearance opening, the light shield 40 being disposed on the support body 11, and the clearance opening avoiding the display screen 12.

[0033] The sunshade 40 is placed around the wearer's eyes to block out light.

[0034] Please see Figure 1 The headband 20 is used to secure the head-mounted display device to the wearer's head. The headband 20 is preferably made of a flexible material.

[0035] In some embodiments, the head-mounted display device may further include a back-head support pad disposed on the headband 20. The back-head support pad is used to contact the back of the wearer's head to provide a certain degree of support.

[0036] Please see Figure 1 and Figure 2 The adapter 30 is used to connect the glasses body 10 and the headband 20. One end of the adapter 30 is connected to the glasses body 10 at a first position X1, and the other end of the adapter 30 is connected to the headband 20 at a second position X2. The height difference between the second position X2 and the first position X1 in the direction of gravity is greater than 0.

[0037] Specifically, please refer to Figure 1 The direction of gravity described here is based on the direction of gravity when the head-mounted display device is worn on the wearer's head and the wearer's eyes are looking straight ahead.

[0038] The adapter 30 has relatively high rigidity, so it mainly serves as a rigid connection.

[0039] Please see Figure 5 The number of adapters 30 can be two, with the two adapters 30 respectively located on opposite sides of the horizontal direction of the eyeglass body 10.

[0040] The connection method between the adapter 30 and the eyeglasses body 10 is not limited. However, in order to facilitate the installation and removal of the adapter 30, one end of the adapter 30 can be detachably connected to the eyeglasses body 10.

[0041] For example, please refer to Figures 1 to 4 The glasses body 10 may be provided with a connection port 10a. One end of the adapter 30 is provided with a mounting part 30a. The mounting part 30a passes through the connection port 10a and is connected to the connection port 10a at a first position X1. That is to say, the setting position of the connection port 10a is equivalent to the first position X1. For example, after the mounting part 30a passes through the connection port 10a, it can be detachably connected to the part of the adapter 30 that does not pass through the connection port 10a. The detachable connection method is not limited. For example, it can be connected by hook and loop fasteners or by fasteners or other components.

[0042] The connection method between the adapter 30 and the headband 20 is not limited. However, in order to improve the stability of the connection between the adapter 30 and the headband 20, the other end of the adapter 30 can be fixedly connected to the headband 20.

[0043] For example, the adapter 30 can be sewn directly onto the headband 20, and the position where the adapter 30 and the headband 20 are sewn together is the second position X2.

[0044] In other embodiments, the adapter 30 and the headband 20 can also be detachably connected. For example, the adapter 30 can have multiple selectable second positions X2, each second position X2 forming a height difference along the direction of gravity. That is, there can be at least two connection positions between the adapter 30 and the headband 20. The wearer can choose a suitable connection position on the adapter 30, so that the adapter 30 can adjust the height of the headband 20 according to different face shapes, thereby enabling the headband 20 to better fit different face shapes.

[0045] Furthermore, each second position X2 can also be set at intervals along the longitudinal direction, which is perpendicular to the direction of gravity. In other words, each second position X2 can also be set at intervals in the direction closer to the back of the wearer's head, which is more conducive to making the headband 20 fit different face shapes.

[0046] In some embodiments, the headband 20 may include an extension for adjusting the length of the headband 20. The extension includes, but is not limited to, Velcro, a stretchable elastic band, an adjustment buckle, etc., wherein the adjustment buckle includes a buckle head with multiple fastening protrusions and a buckle base with multiple fastening holes, and the fastening protrusions achieve length adjustment by fastening with corresponding fastening holes.

[0047] For example, please refer to Figure 2 The headband 20 may include a band body 21 and an extension. The band body 21 includes a first segment 211 and a second segment 212. The head-mounted display device is provided with two adapters 30. The first segment 211 is connected to one of the adapters 30, and the second segment 212 is connected to the other adapter 30. The first segment 211 is provided with a mounting opening 211a. The hook and loop sides of the Velcro are both provided in the second segment 212, and the hook and loop sides are arranged along the extension direction of the second segment 212. After the second segment 212 passes through the mounting opening 211a, the hook and loop sides are hooked together to adjust the length of the headband 20.

[0048] In another embodiment, the elastic band may be connected to the first segment 211 and the second segment 212 of the band body 21 respectively (for example, the opposite ends of the elastic band may be sewn to the first segment 211 and the second segment 212 respectively), or the buckle head of the adjusting buckle may be provided in one of the first segment 211 and the second segment 212, and the buckle seat of the adjusting buckle may be provided in the other of the first segment 211 and the second segment 212.

[0049] In another embodiment, the headband 20 may not have an extension; for example, the entire headband 20 may be an elastic band.

[0050] Please see Figure 1 and Figure 2The adapter 30 actually shifts the second position X2, which connects the adapter 30 to the headband 20, upward relative to the first position X1, so that the height difference between the second position X2 and the first position X1 in the direction of gravity can be greater than 0.

[0051] This application also provides an unmanned aerial vehicle (UAV) system, which includes a UAV and a head-mounted display device provided in any embodiment of this application, wherein the head-mounted display device is signal-connected to the UAV.

[0052] Head-mounted displays can synchronize the operator's perspective with that of the drone. In other words, the drone's camera transmits real-time images to the head-mounted display via wireless signals (such as Wi-Fi, image transmission modules, etc.), allowing the operator wearing the head-mounted display to directly "see" the scene in front of the drone.

[0053] It should be noted that the head-mounted display device described in this application embodiment is not limited to use in drone systems. The head-mounted display device can also be used in other systems and used in conjunction with corresponding devices, or the head-mounted display device can be used alone.

[0054] In related technologies, the headband of a head-mounted display device is directly connected to the glasses. To ensure that the glasses do not deviate from the wearer's eyes, the connection point between the headband and the glasses is generally located in the middle of the glasses along the direction of gravity. However, because the headband is generally made of relatively soft material, it is prone to sagging downwards and pressing on the wearer's ears during the wearing of the head-mounted display device. The head-mounted display device is also prone to tilting, causing the glasses to press against the wearer's cheekbones. Therefore, the wearing comfort of head-mounted display devices in related technologies is relatively poor.

[0055] In this embodiment of the application, the headband 20 and the glasses body 10 of the head-mounted display device are connected by an adapter 30. One end of the adapter 30 is connected to the glasses body 10 at a first position X1, and the other end of the adapter 30 is connected to the headband 20 at a second position X2. The height difference between the second position X2 and the first position X1 in the direction of gravity is greater than 0. Since the adapter 30 acts as a rigid connection between the headband 20 and the glasses body 10, the height difference between the second position X2 and the first position X1 in the direction of gravity will not cause the glasses body 10 to deviate from the wearer's eyes. Since the height difference between the second position X2 and the first position X1 in the direction of gravity is greater than 0, the headband 20 is actually offset upwards away from the wearer's ears. The force point of the headband 20 on the wearer's head is also offset upwards and backwards accordingly. This not only better prevents the headband 20 from collapsing downwards and pressing on the wearer's ears, but also allows the glasses body 10 to be kept more stably on the wearer's face, and almost will not press on the wearer's cheekbone due to tilting. This can effectively improve the wearing comfort of the head-mounted display device.

[0056] Further, please refer to Figure 2 The headband 20 has a back-head force point X3, which is the force point of the headband 20 located at the back of the wearer's head. Preferably, the height difference between the back-head force point X3 and the center of gravity X4 of the glasses body 10 along the direction of gravity can be greater than 0. That is, the height of the back-head force point X3 is higher than the center of gravity X4 of the glasses body 10, so that the headband 20 can be more stably fixed to the wearer's head, and thus better ensure that the glasses body 10 can be more stably maintained on the wearer's face.

[0057] In some embodiments, please refer to Figure 5 The head-mounted display device may also include a forehead support 50, which provides support for the wearer's forehead. The forehead support 50 not only allows the glasses body 10 to fit better against the wearer's face, but also helps to distribute pressure on the glasses body 10, thereby improving the comfort and stability of the head-mounted display device.

[0058] For a head-mounted display device with a light shield 40, a forehead support 50 can be disposed on the light shield 40, thereby reducing the space occupied by the forehead support 50 and making the overall size of the head-mounted display device more compact.

[0059] In some embodiments, the head-mounted display device may further include a cheekbone support member for providing support at the wearer's cheekbone area. Providing a cheekbone support member creates a stress point at the wearer's cheekbone area, thereby reducing the wobbling of the glasses body 10 and further improving the comfort and stability of wearing the head-mounted display device.

[0060] For a head-mounted display device with a light shield 40, the cheekbone support can be installed on the light shield 40, thereby reducing the space occupied by the cheekbone support and making the overall size of the head-mounted display device more compact.

[0061] Figure 1 The head-mounted display device shown includes both a forehead support 50 and a cheekbone support 20. The forehead support 50, cheekbone support 20, and headband 20 work together to form multiple distributed stress points, resulting in greater stability when wearing the head-mounted display device. However, in some embodiments, the head-mounted display device may only have a forehead support 50 without a cheekbone support 20, or only have a cheekbone support 20 without a forehead support 50.

[0062] In other embodiments, the head-mounted display device may also omit the forehead support 50 and the cheekbone support.
