Description

Technical Field

[0001] This utility model relates to the technical field of VR devices, and more particularly to a VR headset. Background Technology

[0002] With the popularization of VR (Virtual Reality) technology, users have put forward higher requirements for the wearing comfort of VR devices. Existing VR headsets are prone to problems such as stuffiness and sweating due to prolonged wear, which seriously affects the user experience. Therefore, it is necessary to set up a corresponding heat dissipation structure in VR headsets. Traditional heat dissipation solutions have many defects, such as: (1) Setting breathable fabric on the headband contact surface: In order to avoid users feeling stuffy, breathable fabric is set on the side of the forehead headband that contacts the user's forehead. For example, the elastic material is wrapped with breathable fabric. The elastic material can reduce the pressure of the forehead headband, and the breathable fabric can increase the heat dissipation of the skin in contact with the forehead headband. However, the heat dissipation of the breathable fabric is still a passive heat dissipation, and the heat dissipation effect is limited, which is difficult to meet the heat dissipation requirements of high power consumption VR devices. (2) Designing corresponding upper and lower air outlet channels: The air coming out through the upper and lower air outlet channels can dissipate heat on the upper part of the forehead and face, but the area of ​​the forehead headband in contact with the skin still cannot be well dissipated, and the heat dissipation effect is not good. Utility Model Content

[0032] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0033] Please refer to Figures 1 to 12 This utility model provides a VR head-mounted device, which includes a main shell 2 and a flexible buffer pad 3 connected to each other. The main shell 2 has a cavity 21 inside, and a ventilation fan 4 is provided in the cavity 21. The inner and outer sides of the main shell 2 are respectively provided with a first through hole 23 and a second through hole 26 communicating with the cavity 21. The flexible buffer pad is provided with a third through hole 31, which is correspondingly connected to the second through hole 26. The flexible buffer pad 3 is used to contact human skin.

[0034] As described above, the beneficial effects of this utility model are as follows: This utility model provides a VR headset with a heat dissipation structure, which achieves active heat dissipation by setting an air exchange fan 4 and a multi-layer through-hole structure in the main shell 2 and the flexible buffer pad 3. In practical applications, the air exchange fan 4 introduces external airflow into the cavity 21 through the first through-hole 23, and through the corresponding connection design of the cavity 21, the second through-hole 26, and the third through-hole 31, directly guides the cool air to the contact area between the flexible buffer pad (i.e., the forehead band) and the user's forehead and face, thereby effectively dissipating heat from the contact area between the forehead band and the user's forehead and face, reducing stuffiness, and improving heat dissipation efficiency, breathability, and wearing comfort. It should be noted that the specific setting position of the above-mentioned fan can be set according to the actual situation, such as being fixedly installed on the main shell 2 or the outer shell 1, and is not limited here.

[0035] Furthermore, such as Figure 11 as well as Figure 12 As shown, in the VR headset of this utility model, the main housing 2 includes a first housing 22 and a second housing 25 connected to each other, and the first housing 22 and the second housing 25 together form the cavity 21.

[0036] As described above, the main housing 2 is divided into a first housing 22 and a second housing 25. This split design simplifies the processing and assembly of the cavity 21. In practical applications, the cavity 21 is elongated, which facilitates more uniform cooling of the contact areas such as the user's forehead and face. Of course, in some embodiments, the main housing 2 can be a one-piece design.

[0037] Furthermore, such as Figure 6 as well as Figure 7As shown, in the VR head-mounted device of this utility model, there is a first assembly gap between the top of the first housing 22 and the top of the second housing 25 to form a first air outlet channel 27, which is connected to the cavity 21.

[0038] In practical applications, a first ventilation channel is provided in the first assembly gap between the inner and outer shells 1, and the first assembly gap is located on the side of the forehead strap facing the top of the head. In this way, the air blown out by the ventilation fan 4 can go upward (i.e., towards the forehead) through the cavity 21 to dissipate heat to the forehead through the first air outlet channel 27.

[0039] As described above, a first air outlet channel 27 is formed between the top of the first housing 22 and the second housing 25, so that the airflow can be evenly distributed to the user's forehead area to avoid local overheating. This design can effectively enhance the heat dissipation effect on the key areas of the forehead.

[0040] Furthermore, such as Figure 6 as well as Figure 7 As shown, in the VR head-mounted device of this utility model, there is a second assembly gap between the bottom of the first housing 22 and the bottom of the second housing 25 to form a second air outlet channel 28, which is connected to the cavity 21.

[0041] In practical applications, a second air outlet channel 28 is formed by the second assembly gap between the inner and outer shells 1, with the second assembly gap located on the side of the forehead band facing the face. In this way, the air blown out by the ventilation fan 4 can travel downwards (i.e., towards the face) through the cavity 21 to dissipate heat from the face through the second air outlet channel 28.

[0042] As described above, a second air outlet channel 28 is provided between the bottom of the first housing 22 and the second housing 25, further expanding the airflow coverage and allowing cool air to simultaneously reach the forehead and the area below the face. In summary, the design of dual air outlet channels achieves three-dimensional heat dissipation, enhances the heat dissipation effect, and reduces the problem of uneven heat dissipation caused by relying on a single air outlet path.

[0043] Furthermore, such as Figure 12 As shown, in the VR headset of this utility model, the second housing 25 includes a first housing portion 251, a second housing portion 252, and a third housing portion 253 that are sequentially snapped together. Each of the first housing portion 251, the second housing portion 252, and the third housing portion 253 is provided with a second through hole 26. In practical applications, the ventilation fan 4 is mounted on the second housing portion 252, and the ventilation fan 4 extends from the second housing portion 252 into the first through hole 23.

[0044] As described above, the second housing 25 adopts a three-section snap-fit ​​design (i.e., the first housing section 251, the second housing section 252, and the third housing section 253), with each housing section independently provided with a second through hole 26. This design allows airflow to be evenly discharged from the cavity 21 of the main housing 2 through multiple segmented second through holes 26, covering a wider heat dissipation area and avoiding the problems of local airflow concentration or dead zones caused by traditional single through holes, significantly improving heat dissipation uniformity and heat dissipation effect.

[0045] Furthermore, such as Figure 1 as well as Figure 3 As shown, the VR headset of this utility model also includes a housing 1, on which an air inlet 11 communicating with the first through hole is provided, and an air vent 11 is provided in the air inlet 11. In practical applications, the air inlet can be set into a mesh shape, a louver shape, or other shapes.

[0046] As described above, an air inlet 11 is provided on the outer casing 1 at a corresponding and connected position. Through the air inlet 11, external air can be introduced into the first through hole 23 and then into the cavity 21. In addition, a wind grille is provided on the air inlet 11 to effectively block external foreign objects (such as hair) from entering the cavity 21, thus preventing the fan from being blocked or damaged.

[0047] Furthermore, such as Figure 3 as well as Figure 11 As shown, in the VR headset of this utility model, the main housing 2 is provided with a slot 24, and the outer shell 1 is fitted into the slot 24; and / or, the air vent includes a horizontal grille and a vertical grille.

[0048] As described above, the main housing 2 has a slot 24, and the outer housing 1 is fixed in the slot 24 by a snap-fit ​​method, which simplifies the assembly process of the outer housing 1 and the main housing 2 and improves the connection stability between the two. In addition, the air inlet 11 can also be equipped with a horizontal and vertical grille structure to effectively block foreign objects from entering the cavity 21 and avoid fan blockage or damage.

[0049] Furthermore, in the VR headset of this invention, the flexible cushioning pad includes an elastic breathable layer and an outer cover layer. The third through-hole is disposed on the elastic breathable layer, and the outer cover layer covers the elastic breathable layer. The outer cover layer is for contact with human skin. As can be seen from the above description, the contact between the flexible cushioning pad and the skin can improve wearing comfort.

[0050] It should be noted that the outer layer may or may not have a fourth through hole; the specific arrangement can be chosen according to the actual situation. If a fourth through hole is provided on the outer layer, it can be connected to the third through hole. In practical applications, the material of the outer layer can be selected according to the actual situation, such as breathable fabric (e.g., nylon mesh) or leather.

[0051] In some alternative embodiments, the flexible cushioning pad may include a sponge layer and a flexible layer, employing a composite structure of sponge and flexible layers to provide cushioning support and ensure comfort during wear.

[0052] Furthermore, in the VR headset of this invention, the flexible cushioning pad is detachably connected to the main housing.

[0053] Furthermore, in the VR headset of this invention, the flexible cushioning pad is magnetically connected to the main housing.

[0054] In practical applications, for ease of installation and use, the flexible buffer pad is detachably connected to the main housing. There are various ways to achieve this detachable connection. For example, the flexible buffer pad 3 can be detachably installed on the main housing 2 via magnetic attraction, snap-fit, or Velcro. Of course, in some embodiments, both ends of the flexible buffer pad 3 can also be detachably connected to the outer housing 1. Furthermore, the flexible buffer pad 3 may also include a mounting plate facing the main housing 2. The mounting plate is made of plastic and has corresponding fifth through holes.

[0055] Please refer to Figures 1 to 12 A preferred embodiment of this utility model is: a VR head-mounted device, which includes a forehead headband, such as... Figure 1 , Figure 2 as well as Figure 3 As shown, the forehead band includes an outer shell 1, a main shell 2, and a flexible cushioning pad 3 connected sequentially from the outside to the inside. The outer shell 1 is disposed on the outer side of the main shell 2. Specifically, a slot 24 is formed in the main shell 2, and the outer shell 1 is fitted into the slot 24. An air inlet 11 is formed in the outer shell 1, and an air grille is provided in the air inlet 11, which includes horizontal and vertical grilles.

[0056] In this embodiment, as Figure 6 as well as Figure 7As shown, the main housing 2 includes a first housing 22 and a second housing 25 connected to each other. The first housing 22 and the second housing 25 together form a cavity 21, and a ventilation fan 4 is provided in the cavity 21. The second housing 25 includes a first housing portion 251, a second housing portion 252, and a third housing portion 253 that are sequentially snapped together. Based on the ventilation fan 4, this embodiment provides two heat dissipation structures to enhance the heat dissipation effect. These two heat dissipation structures are described in detail below.

[0057] In this embodiment, as Figure 9 as well as Figure 10 As shown, the first heat dissipation structure is specifically configured as follows: The inner and outer sides of the main housing 2 are respectively provided with a first through hole 23 and a second through hole 26 communicating with the cavity 21. The first through hole 23 is located on the first housing 22, corresponding to and communicating with the air inlet 11. Multiple second through holes 26 are arranged in three groups, respectively located on the first housing portion 251, the second housing portion 252, and the third housing portion 253. Correspondingly, the flexible buffer pad 3 includes an outer covering layer and an elastic breathable layer. A third through hole 31 is provided on the elastic breathable layer, corresponding to and communicating with the second through holes 26. The outer covering layer is used for contact with human skin. An air exchange fan 4 is mounted on the second housing portion 252, extending from the second housing portion 252 into the first through hole 23. Based on the above structural configuration, the airflow channel of the first heat dissipation structure includes, from the outside to the inside, an air inlet 11, a first through hole 23, a second through hole 26, and a third through hole 31. This airflow channel allows for cooling of the area where the forehead headband contacts the skin. Specifically, external air can enter the cavity through the air inlet 11 and the first through hole 23 via a ventilation fan. Since the second housing 25, which forms the cavity, has multiple second through holes 26, and these second through holes 26 are connected to the third through hole 31, the air blown into the cavity 21 can sequentially enter the second through holes 26 and the third through hole 31, achieving direct cooling of the outer covering layer, thereby achieving direct cooling of the area where the forehead headband contacts the skin.

[0058] In this embodiment, as Figure 6 as well as Figure 7As shown, the second heat dissipation structure is specifically configured as follows: A first assembly gap exists between the top of the first housing 22 and the top of the second housing 25 to form a first air outlet channel 27, which communicates with the cavity 21. A second assembly gap exists between the bottom of the first housing 22 and the bottom of the second housing 25 to form a second air outlet channel 28, which communicates with the cavity 21. Based on the above structural configuration, external gas can enter through the air inlet 11, and the ventilation fan 4 blows the gas entering through the air inlet 11 into the cavity. Since there is a first assembly gap between the tops of the first housing 22 and the second housing 25, and a second assembly gap between the bottoms of the first housing 22 and the second housing 25, the first air outlet channel 27 and the second air outlet channel 28, which communicate with the cavity 21, can be correspondingly formed. In practical applications, the first air outlet 27 can blow air upwards to dissipate heat, such as cooling the forehead, while the second air outlet 28 can blow air downwards to dissipate heat, such as cooling the face.

[0059] In summary, the VR headset provided by this utility model achieves active heat dissipation by incorporating a ventilation fan 4 and a multi-layered through-hole structure within the outer shell 1, main shell 2, and flexible buffer pad 3. In practical applications, the ventilation fan 4 introduces external airflow into the cavity 21 through the air inlet 11 and the first through-hole 23. Through the corresponding interconnected design of the first through-hole 23, the second through-hole 26, and the third through-hole 31, the cool air is directly directed to the contact area between the outer cover (i.e., the forehead band) and the user's forehead and face, significantly improving heat dissipation efficiency, reducing stuffiness, and enhancing breathability and wearing comfort.
