Description

Head mounted display

The present invention relates to an augmented reality technology, and in particular to a head-mounted display device.

Augmented Reality (AR) is a technology that combines virtual images or images with real scenes, and the most common hardware device is augmented reality glasses. In detail, users can wear augmented reality glasses on their heads and view the real scene in front of them through the lenses to integrate virtual and real scenes with the virtual images or images projected onto the lenses by the optical module.

Generally speaking, due to the battery capacity, the usage time of augmented reality glasses is relatively limited, which affects the user's operating experience.

FIG. 1C is a schematic diagram of the configuration of internal components of the head-mounted display device of FIG. 1B. Referring to FIG. 1A to FIG. 1C, in this embodiment, the head-mounted display device 100 includes a lens frame 110, two lenses 120, an optical module 130, two temples 140, and a power module, wherein the two lenses 120 are disposed on the lens frame 110, and the optical module 130 is disposed in the lens frame 110 to project a virtual image or video onto the two lenses 120. On the other hand, two temples 140 are respectively connected to opposite sides of the lens frame 110, wherein each temple 140 has a front end 141 connected to the lens frame 110 and a rear end 142 opposite to the front end 141, and the power module is detachably mounted on the two rear ends 142 of the two temples 140. The optical module of the present invention includes but is not limited to electronic devices applied to virtual reality (VR), augmented reality (AR), mixed reality (MR), etc. The head-mounted display device of this embodiment is exemplified by taking AR glasses as an example.

Specifically, the power module includes two external power sources 150, and the two external power sources 150 are detachably mounted on the two tail ends 142 of the two temples 140. Therefore, the user can install a large-capacity power module according to personal needs to improve battery life, or quickly replace the power module when the power module is exhausted to avoid interrupting the experience or affecting the mobility. On the other hand, the power module adds a weight to the tail end 142 of the temple 140 to prevent the temple 140 from slipping off the user's ear, thereby helping to improve the stability of wearing.

As shown in FIG. 1A and FIG. 1B , each temple 140 further has a positioning hole 143 at the rear end 142, wherein each external power source 150 has a positioning protrusion 151, and each positioning protrusion 151 of the external power source 150 is engaged with the positioning hole 143 of the corresponding temple 140. The cooperation between the positioning protrusion 151 and the positioning hole 143 can not only prevent the external power source 150 from accidentally detaching from the temple 140, but also assist the user to quickly and accurately install the external power source 150 on the temple 140. Furthermore, by the friction resistance between the positioning protrusion 151 and the positioning hole 143, the external power source 150 can be stably attached to the rear end 142 of the temple 140 and is not easy to detach from the temple 140.

When each external power source 150 is attached to the tail end 142 of the corresponding temple 140, the positioning protrusion 151 is engaged with the positioning hole 143, and the first conductive element 145 contacts the second conductive element 153 to be electrically connected to the second conductive element 153. The first conductive element 145 and the second conductive element 153 that are in contact with each other are two conductive contacts that are in contact with each other and are used to transmit the power of the external power source 150 to the electronic components disposed in the temple 140 and the frame 110 .

As shown in FIG. 2B and FIG. 2C , the first conductive element 145 of each temple 140 is located between the first magnetic element 144 and the positioning hole 143. Correspondingly, in each external power source 150, the positioning protrusion 151, the second magnetic element 152 and the second conductive element 153 are adjacent to each other, and the second conductive element 153 is located between the second magnetic element 152 and the positioning protrusion 151. Therefore, by the positioning design of the second magnetic element 152 and the first magnetic element 144 and the positioning design of the positioning protrusion 151 and the positioning hole 143, the second conductive element 153 can accurately contact the first conductive element 145 to improve the stability of power transmission.

On the other hand, the first conductive element 145 is disposed on the inner surface 146, wherein the first magnetic element 144 can be disposed in the temple 140 and adjacent to the inner surface 146, or the first magnetic element 144 can be disposed on the inner surface 146. Therefore, each external power source 150 is installed and positioned with the side where the positioning protrusion 151, the second magnetic element 152 and the second conductive element 153 are located facing the inner surface 146 of the corresponding temple 140.

As shown in FIG. 2D and FIG. 2E , the positioning protrusion 151 of each external power source 150 is inserted into the positioning hole 143 from the inner surface 146 of the corresponding temple 140 to be attached to the inner surface 146 of the corresponding temple 140 .

As shown in FIG. 2B and FIG. 2E , the inner surface 146 of each temple 140 is provided with a positioning groove 148 at the rear end 142, and the positioning hole 143 is connected to the positioning groove 148. The first conductive element 145 is located in the positioning groove 148, and the first magnetic element 144 is located outside the positioning groove 148. Each external power source 150 includes a positioning boss 154, wherein the second conductive element 153 is disposed on the positioning boss 154, and the positioning protrusion 151 is convexly disposed on the positioning boss 154.

When the positioning protrusion 151 of each external power source 150 is inserted into the positioning hole 143 from the inner surface 146 of the corresponding temple 140, the positioning boss 154 is inserted into and engaged with the positioning groove 148. The cooperation between the positioning protrusion 151 and the positioning hole 143 and the cooperation between the positioning boss 154 and the positioning groove 148 can not only improve the accuracy of the installation and positioning of the external power source 150, but also prevent the external power source 150 from slipping on the inner surface 146 of the temple 140, thereby causing the second conductive element 153 to be electrically separated from the first conductive element 145.

As shown in FIG. 2B , FIG. 2D and FIG. 2E , the positioning hole 143 of each temple 140 has a positioning inclined surface 1431 extending toward the first conductive element 145 and connected to the inner surface 146, and the positioning inclined surface 1431 is a part of the inner wall surface of the positioning hole 143. Therefore, the aperture D of the positioning hole 143 decreases from the inner surface 146 to the outer surface 147. In the process of inserting the positioning protrusion 151 into the positioning hole 143, the positioning inclined surface 1431 can guide the positioning protrusion 151 to improve the smoothness of the installation and positioning.

In other examples, the positioning hole 143 may be a blind hole that is recessed relative to the inner surface 146 and does not penetrate the outer surface 147 .
