[0041] Currently, AR or VR devices have various forms, such as glasses or helmets, which have great problems in wearing experience. They are heavy, uncomfortable to wear, and cannot be worn for a long time, especially in some sports scenes. In addition, in sports scenes, such as marathons or other scenes, athletes will wear bracelets or other health detection data, but they have to frequently raise their wrists to check during exercise, which is inconvenient.

[0042] In view of the above defects, the present application proposes a head display device, a sports head display device and a virtual product. The present application provides a head display device, referring to Figure 1 , Figure 1 This is a schematic diagram of the structure of the head display device provided in this application, and the head display device includes:

[0043] An elastic headband 10, wherein a brim 20 extending forward is provided at the front of the elastic headband 10, and the brim 20 is fixedly adhered to the front of the elastic headband 10;

[0044] A free-form surface 30, wherein the free-form surface 30 is disposed on the inner surface of the brim 20;

[0045] An optical machine module 40, wherein the optical machine module 40 is disposed on one side of the inner surface of the brim 20 close to the front portion of the elastic headband 10;

[0046] The elastic headband 10 is fixed on the wearer's head. After the optical module 40 generates an image signal, the optical module 40 converts the image signal into an optical signal and projects it onto the free-form surface 30 , and displays the image projected by the optical signal via the free-form surface 30 .

[0047] In this embodiment, refer to Figure 1 The head display device of the present application is composed of a headband 10 and a brim 20, and a free-form surface 30 is arranged on the inner surface of the brim 20, and then an optical module 40 is arranged on the inner surface of the brim 20 near the front of the elastic headband 10. After the wearer puts on the head display device, that is, after the elastic headband 10 is fixed on the wearer's head, the free-form surface 30 provided in the present application can ensure that the light signal projected in real time by the optical module 40 can be effectively reflected into the wearer's field of view based on the AR free-form surface technology, which not only realizes the display of high-quality images, but also displays the display image projected by the light signal through the free-form surface 30, so that the display image can present a more realistic and three-dimensional effect in the wearer's field of view, thereby providing the wearer with an efficient, convenient and comfortable virtual reality or augmented reality experience.

[0048] It should be noted that since the optical-mechanical module 40 can update the image or video signal in real time, the wearer can observe in real time the content projected and displayed by the free-form surface 30 provided on the inner surface of the brim 20, so that the wearer does not need to frequently raise his hand to check the data on devices such as watches or bracelets, which significantly improves the convenience and safety of using the head-mounted display device.

[0049] The front of the elastic headband 10 of the present application is provided with a forward-extending brim 20, which can effectively protect the wearer's eyes from interference from external light or debris, and also has a certain sunshade function, which is particularly important when using the head display device outdoors, and can effectively improve the wearer's experience. In addition, the free-form surface 30 provided on the inner surface of the brim 20 of the present application can provide a high-quality display platform for the optical machine module 40 to project images, which helps to improve the clarity and detail of the displayed image, so that the wearer can get a better virtual reality experience.

[0050] In addition, it should be noted that the angle between the elastic headband 10 and the brim can be customized, the optical machine module 40 can be understood as a micro projector, and the free-form surface 30 provided in the present application can also be replaced by an optical waveguide or a prism. The above is only a feasible implementation method of the present application, and the present application does not impose any limitations here.

[0051] In summary, the elastic headband 10 provided in the present application can be adaptively adjusted according to the head circumference of the wearer, ensuring that the head display device can be tightly and comfortably fixed on the wearer's head, reducing the discomfort caused by shaking or sliding. Then, a brim 20 that protrudes forward is provided at the front of the elastic headband 10, and the brim 20 is fixedly bonded to the front of the elastic headband 10, so that the connection between the headband 10 and the brim 20 is more secure and not easy to separate during movement, thereby improving the stability of the head display device wearing support. Next, the present application sets the free-form surface 30 on the inner surface of the brim 20, and sets the optical module 40 on the inner surface of the brim 20 near the front side of the elastic headband 10, so that the optical module 40 can convert the image signal generated by itself into an optical signal which can be accurately projected onto the free-form surface 30, and present a high-quality and clear display image through the free-form surface 30. A good visual experience can be provided without the need for an additional VR glasses body, and the entire head-mounted display device is made more compact, reducing unnecessary weight and volume, while also improving the wearing comfort and adaptability, thereby significantly improving the reliability of the wearing support of the head-mounted display device.

[0052] Furthermore, in some feasible embodiments, the outer surface of the brim 20 is covered with a dark plastic plate.

[0053] In this embodiment, the outer surface of the brim 20 is covered with a dark plastic plate, which can effectively filter out the interference of external ambient light on the imaging of the free-form surface 30, thereby improving the clarity of the displayed image projected by the free-form surface 30 displaying the light signal.

[0054] It should be noted that the dark plastic plate can be understood as a black plastic plate or an opaque plastic plate.

[0055] Exemplarily, the dark plastic plate covered on the outer surface of the brim 20 of the present application can effectively filter out the interference of external ambient light on the imaging of the free-form surface 30. Outdoors or in an environment with strong light, external light may have an adverse effect on the imaging of the free-form surface 30, resulting in reduced clarity of the displayed image. The dark plastic plate has the characteristic of absorbing light, which can significantly reduce the interference of external light on the free-form surface 30, thereby improving the clarity of the displayed image. In addition, the use of the dark plastic plate further enhances the sunshade function of the head display device. It can not only block direct sunlight and reduce screen reflections, but also further reduce the stimulation of external light to the wearer's eyes and improve wearing comfort.

[0056] Further, in some other feasible embodiments, referring to Figure 2 The headband 10 is in the shape of an elastic strip, a first side of the headband 10 is fixedly connected to an elastic fixing strip 101, and a second side of the headband is fixedly connected to a rubber mounting block 102;

[0057] The rubber installation block 102 is connected to the elastic fixing strip 101 through a slot.

[0058] In the present embodiment, the headband 10 is designed to be in an elastic strip shape, and this design enables the headband 10 to be adaptively adjusted according to the user's head shape, providing better wearing comfort and stability. The elastic strip-shaped headband 10 can evenly distribute pressure on different head shapes, reduce discomfort, and at the same time ensure sufficient support force to prevent the head display device from slipping during movement. Exemplarily, the elastic fixing strip fixedly connected to the first side of the headband 10, and the rubber mounting block fixedly connected to the second side of the headband 10, the rubber mounting block is connected to the elastic fixing strip through a card slot, which is not only easy to install, but also relatively easy to disassemble, which is convenient for users to clean or replace parts. In addition, the use of the rubber mounting block also increases the flexibility and durability of the connection, which can adapt to the use requirements under different conditions.

[0059] Further, in some feasible embodiments, the headband 10 includes a fabric layer and an insulating layer;

[0060] The cloth layer is in a ring shape and wraps around the insulating layer. The length of the cloth layer is the same as that of the insulating layer.

[0061] In this embodiment, the headband 20 is composed of a cloth layer and an insulating layer, and the cloth layer wraps the insulating layer. This design not only provides a good touch and makes wearing more comfortable, but also the presence of the insulating layer ensures safety of use and prevents current from directly contacting the user's skin.

[0062] Further, in some other feasible embodiments, referring to Figure 3 , Figure 3This is a schematic diagram of the insulating layer structure involved in another embodiment of the head display device provided by the present application. The head display device further includes a control module X1, a battery module X2, a sensor module X3 and a communication module X4, and the insulating layer includes a strip groove Y1 and a strip cover plate Y2.

[0063] The control module X1 is electrically connected to the battery module X2, the sensor module X3 and the communication module X4 respectively;

[0064] The control module X1, the battery module X2, the sensor module X3 and the communication module X4 are fixedly connected in the strip-shaped groove at preset intervals;

[0065] The strip cover plate Y2 covers the strip groove Y1 and is fixedly connected to the strip groove Y1 by a bayonet.

[0066] In this embodiment, the control module X1, the battery module X2, the sensor module X3 and the communication module X4 are fixedly connected in the strip groove at preset intervals. This layout not only makes the internal structure of the head display device more compact, but also can reduce the performance degradation caused by mutual interference between modules, and also facilitates the maintenance and replacement of the modules. In addition, the strip cover Y2 covers the strip groove Y1 and is fixedly connected to the strip groove Y1 bayonet. This design effectively protects the internal electrical component modules, prevents damage caused by external impact or friction, and increases the service life of the head display device.

[0067] Further, in some other feasible embodiments, the control module X1 is a microcontroller, and the battery module X2 is a microbattery;

[0068] The sensor module X3 is a lightweight sensor, which includes at least an ultraviolet sensor and a temperature sensor;

[0069] The communication module X4 is Bluetooth, and the microcontroller is connected to the optical machine module 40 and external devices respectively through the Bluetooth. The external devices include at least a sports bracelet, a heart rate belt and a mobile phone.

[0070] In this embodiment, the control module X1 adopts a microcontroller, the battery module X2 adopts a microbattery, the sensor module X3 adopts a lightweight sensor, and the communication module X4 adopts Bluetooth technology, thereby achieving the purpose of lightweight and high efficiency of the head display state. While ensuring the performance of the entire head display device, it also greatly reduces the weight and volume of the entire head display device, thereby enhancing the reliability of the wearing support of the head display device during the wearing process.

[0071] It should be noted that the communication module X4 provided in the head display of the present application can transmit the health data collected by the external device to the optical machine module 40 in real time for display and viewing. Among them, the external device includes but is not limited to a sports watch, a sports bracelet, a heart rate belt and a mobile phone, etc., and the health data includes but is not limited to heart rate, body temperature and blood oxygen.

[0072] Lightweight sensors can be customized according to user needs. Lightweight sensors include but are not limited to UV sensors, temperature sensors, heart rate sensors, body temperature sensors, blood oxygen sensors, wearable detection sensors, etc.

[0074] Further, in some feasible embodiments, the fabric layer comprises at least a first cotton fabric layer, a sponge layer and a second cotton fabric layer;

[0075] The first cotton cloth layer, the sponge layer and the second cotton cloth layer are sequentially stacked and fixedly connected;

[0076] The insulating layer is an insulating elastic plastic layer.

[0077] In this embodiment, by adopting the method of stacking and fixing the first cotton layer, the sponge layer and the second cotton layer in sequence, the first and second cotton layers provide a soft and comfortable touch, and the sponge layer also has good cushioning performance, which can reduce the pressure on the head and further improve the comfort of wearing. In addition, the first and second cotton layers have good sweat absorption and air permeability, which can effectively absorb the sweat generated by the head, keep the wearing part dry, and avoid the discomfort caused by sweat accumulation. In addition, the insulating layer provided in the present application adopts an insulating elastic plastic layer, which not only has good insulation performance, can effectively isolate the current, reduce the risk of electric shock, and protect people's safety, but also its elastic properties make the headband better adapt to different head shapes, and improve the stability and comfort of wearing. In other words, the present application closely combines the first cotton layer, the sponge layer and the second cotton layer to form a stable overall structure by stacking and fixing. The structural strength and durability of the headband are improved, so that it can withstand the friction and impact in daily use.

[0078] Furthermore, in some other feasible embodiments, the free-form surface 30 is an optical component.

[0079] In this embodiment, the free-form surface 30 can be understood as an optical lens with a certain refractive index and reflective index.
