Description

Technical Field

[0001] This invention relates to the field of smart electronic products technology, and more specifically, to a head-mounted device. Background Technology

[0002] Currently, head-mounted devices such as smart glasses, AR headsets, and VR headsets are increasingly appearing in daily life. Many existing head-mounted devices mainly consist of a main body and support legs installed on the left and right sides of the main body, which are then worn on the user's head.

[0003] Taking AR glasses as an example, existing AR glasses are too heavy to meet the needs of users for comfortable wear for a long time. In addition, due to different head shapes, the glasses may be too loose or too tight, resulting in poor fit and discomfort, thus leading to a poor wearing experience.

[0004] In order to solve the above problems, the present invention urgently needs to provide a new head-mounted device. Summary of the Invention

[0005] In view of the above problems, the purpose of this invention is to provide a head-mounted device to solve the problem that traditional head-mounted devices cannot meet the user's need for comfortable wearing due to their heavy weight and different head shapes.

[0006] This invention provides a head-mounted device, comprising: a device body, a nose pad disposed in the middle of the device body, temples respectively disposed on the left and right sides of the device body, and an elastic bracket disposed between each temple and the device body, wherein...

[0007] The elastic support is used to adjust the angle of the temple, and the temple can be rotated at least two degrees of freedom.

[0008] Furthermore, in a preferred configuration, the two degrees of freedom angular flipping include inward and outward degree of freedom flipping and up and down degree of freedom flipping, the inward and outward degree of freedom flipping includes inward flipping and outward flipping, and the up and down degree of freedom flipping includes upward flipping and downward flipping.

[0009] Furthermore, a preferred structure is that when the temple is subjected to an outward force, the temple rotates outward by 10-45 degrees under the action of the elastic bracket.

[0010] Furthermore, a preferred structure is that when the temple is subjected to an upward force, the temple flips upward by 0-30 degrees under the action of the elastic bracket.

[0011] Furthermore, in a preferred configuration, the elastic support includes a bending region and fixed regions disposed at both ends of the bending region, wherein the bending region undergoes elastic movement under external force, and the elastic support is fixed to the device body and the temple of the mirror respectively through the fixed regions.

[0012] Furthermore, a preferred configuration is that the bending region includes a spring and a soft rubber covering the outer periphery of the spring, the spring and the soft rubber being injection molded together.

[0013] Furthermore, a preferred structure is that when the bending area is subjected to an external force, the soft rubber and the spring move elastically together.

[0014] Furthermore, a preferred configuration is that the spring is a helical structure, with a helical gap provided between the helical structures.

[0015] When the temple is subjected to an external force, the temple rotates by a preset angle along the direction of the force under the action of the helical gap.

[0016] Furthermore, a preferred structure is that the fixing area is fixed to both ends of the spring, and the fixing area is connected to the device body or the temple of the mirror by screws or glue; or,

[0017] A plastic part is embedded in the fixed area, and the fixed area is injection molded to the main body of the device or the temple of the mirror through the plastic part.

[0018] Furthermore, a preferred structure is that the soft adhesive is silicone, liquid silicone, fluororubber, TPE, TPU, or TPSIV.

[0019] As can be seen from the above technical solution, the head-mounted device provided by this invention connects the main body of the device to the temples via an elastic bracket. The elastic bracket is used to adjust the angle of the temples, allowing the temples to rotate at least two degrees of freedom. The temples can not only rotate inwards or outwards, but also upwards or downwards. When a user wears the glasses, the elastic bracket can rotate outwards at a certain angle according to the actual size of the user's head, ensuring a close fit between the temples and the user's head shape. The outward rotation angle of the elastic bracket can be designed to be suitable, thus well accommodating different head sizes. Similarly, since the elastic bracket has another degree of freedom, when a user wears the glasses, the elastic bracket adjusts the upward rotation angle of the temples according to different head shapes, thus accommodating users with different head shapes. Through the adjustment of these two degrees of freedom, a larger area of ​​contact between the glasses and different user head shapes can be increased, providing users with a more comfortable and reliable wearing experience. Furthermore, while maintaining the same wearing comfort, the glasses can have more internal functions.

[0020] To achieve the foregoing and related objectives, one or more aspects of the invention include the features that will be described in detail below. The following description and accompanying drawings illustrate certain exemplary aspects of the invention. However, these aspects indicate only a few of the various ways in which the principles of the invention can be used. Furthermore, the invention is intended to encompass all such aspects and their equivalents. Attached Figure Description

Therefore, they should not be construed as limitations on this invention.

[0034] In response to the aforementioned problem that traditional head-mounted devices cannot meet users' needs for comfortable wear due to their heavy weight and different head shapes, this invention proposes a head-mounted device.

[0035] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0036] To illustrate the structure of the head-mounted device provided by the present invention, Figures 1 to 7 The structure of the head-mounted device is illustrated by way of example from different angles. Specifically, Figure 1 The overall structure of the head-mounted device according to an embodiment of the present invention is shown; Figure 2 An exploded structure of a head-mounted device according to an embodiment of the present invention is shown; Figure 3 An explosive structure of an elastic support according to an embodiment of the present invention is shown; Figure 4 A three-dimensional structure of an elastic support according to an embodiment of the present invention is shown; Figure 5 A cross-sectional structure of an elastic support according to an embodiment of the present invention is shown; Figure 6 An outward-folding structure of a head-mounted device according to an embodiment of the present invention is shown; Figure 7 A head-mounted device flip-up structure according to an embodiment of the present invention is shown.

[0037] like Figures 1 to 7 As shown in the figure, the head-mounted device provided by the present invention includes: a device body 1, a nose pad 7 disposed in the middle part of the device body 2, temples respectively disposed on the left and right sides of the device body 1, and an elastic bracket disposed between each temple and the device body 1, wherein the elastic bracket is used to adjust the angle of the temple, and the temple can be rotated at least two degrees of freedom.

[0038] In this invention, the main body 1 of the device has a symmetrical structure on both sides. The left and right temples located on both sides of the main body 1 can be referred to as the first temple and the second temple, respectively. The left and right temples correspond to the first temple 3 or the second temple 5, respectively, without limitation. The first temple 3 is connected to the main body 1 through a first elastic bracket 2, and the second temple 5 is connected to the main body 1 through a second elastic bracket 6. Each elastic bracket adjusts the angle of the connected temple. Due to the elastic structure of the elastic bracket, the temple can be adjusted not only left and right (inward or outward) but also up and down (upward or downward) to meet the user's head-wearing needs. That is, when the temple is subjected to external force, the elastic bracket supports the corresponding temple to rotate a certain angle in four directions (inward or outward, upward or downward), so that the temple can adapt to users with different head shapes, while increasing the contact area between the temple and the head, improving the stability and comfort when wearing it; when the external force is removed, the temple will automatically return to its original position under the action of the elastic bracket.

[0039] exist Figure 3 , Figure 4 and Figure 5 In the illustrated embodiment, the elastic support includes a bending region 23 and fixed regions disposed at both ends of the bending region 23. The bending region 23 undergoes elastic movement under external force, and the elastic support is fixed to the device body 1 and the temple via the fixed regions. The bending region 23 includes a spring 21 and soft rubber 22 surrounding the spring 21, which are injection molded together. When the bending region 23 is subjected to external force, the soft rubber 22 and the spring 21 undergo elastic movement together. Fixed regions connected to the device body 1 and the temple are respectively disposed at both ends of the spring 21; these fixed regions are not injection molded to the soft rubber 22. Specifically, the two ends of the spring 21 are a first fixed region 211 and a second fixed region 212, with the first fixed region 211 connected to the device body 1 and the second fixed region 212 connected to the corresponding temple.

[0040] It should be noted that during the injection molding of spring 21 and soft rubber 22, the first fixing area 211 and the second fixing area 212 are not injection molded together with the soft rubber 22. The first fixing area 211 can be connected to the main body 1 of the device using glue and screws, and the second fixing area 212 can be connected to the corresponding temple using glue and screws. Alternatively, injection molded parts can be provided on both the first fixing area 211 and the second fixing area 212. The first fixing area 211 is injection molded to the main body 1 using injection molded parts, and the second fixing area 212 is injection molded to the corresponding temple using injection molded parts. In specific applications, depending on the actual situation, appropriate connection methods can be selected to connect the fixing areas to the main body 1 and the corresponding temple respectively, and it is not limited to a specific method.

[0041] exist Figure 5 In the illustrated embodiment, spring 21 has a helical structure with a helical gap C1 between the helical structures. When the temple is subjected to an external force, the temple rotates by a preset angle along the direction of the force under the action of the helical gap. The helical gap C1 supports the temple's rotation in four directions (inward or outward, upward or downward). The spring diameter C2 determines the magnitude of the spring force of spring 21. The overall shape of spring 21 controls the difference in the magnitude of the spring force in the four directions. The inner diameter C3 formed by the spring accommodates the seam between the temple and the frame.

[0042] Spring 21 is made of metal, such as steel, stainless steel, titanium alloy, high-carbon steel, or high-strength steel. The appropriate material can be selected for the specific application. Soft rubber 22 can be made of silicone, liquid silicone, fluororubber, TPE, TPU, TPSIV, or other soft rubber materials. Spring 21 is injection molded to soft rubber 22 using inserts, such as… Figure 4 As shown, the elastic part of the spring 21 is completely embedded in the soft rubber 22. When the spring 21 deforms, it will pull the soft rubber 22 to deform together, thus completing the adjustment of the temple angle.

[0043] In an embodiment of the present invention, an elastic bracket is provided between the device body 1 and the temple, allowing the temple to rotate at least two degrees of freedom. These two degrees of freedom include inward / outward rotation and upward / downward rotation. Inward / outward rotation includes inward and outward rotation, while upward / downward rotation includes upward and downward rotation. In other words, the elastic bracket allows the temple to deform in two free directions (four directions: upward or downward, outward or inward). When the temple is subjected to an external force, it rotates by a preset angle along the direction of the force under the action of the elastic bracket. When the temple is subjected to an inward / outward force, it rotates inward or outward under the action of the elastic bracket; when subjected to a downward / downward force, it rotates upward or downward under the action of the elastic bracket. This allows the temple to accommodate users with different head shapes and increases the contact area between the temple and the head.

[0044] exist Figure 6 In the illustrated embodiment, when a user wears the glasses, the flexible frame tilts outward at a certain angle according to the user's actual head size, allowing the temples to fit snugly against the head. The outward tilt angle D2 of the flexible frame can be designed as a large tilt angle of 10-45 degrees as needed, thus well accommodating different head sizes D1, generally ranging from 136mm to 172mm. Furthermore, within this degree of freedom, it can also tilt inward at a certain angle according to the user's head shape, satisfying the wearing comfort of users with different head shapes.

[0045] exist Figure 7 In the illustrated embodiment, because the flexible frame has another degree of freedom, when a user wears the glasses, the flexible frame will adjust the upward tilt angle D3 of the second temple according to different head shapes, generally from 0 to 30 degrees, thereby meeting the wearing needs of users with different head shapes. Furthermore, within this degree of freedom, it can also tilt downwards at a certain angle according to the user's head shape, thereby meeting the wearing comfort needs of users with different head shapes.

[0046] pass Figure 6 and Figure 7 The two degrees of freedom adjustment in the embodiment can increase the fit of the head-mounted device to a larger area of ​​different user head shapes, providing users with a more comfortable and reliable wearing experience; while maintaining the same wearing feel, it allows the glasses to have more functions (such as increasing weight).
