Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 schematically shows a head mounted smart device 1 as a whole, according to an embodiment of the present invention. As shown in fig. 1, a head-mounted smart device 1 (hereinafter, referred to as a smart device 1) includes a smart component 100 and a headband 200 connected to the smart component 100. The headband 200 is configured to be foldable. Thus, the user can conveniently wear the intelligent device 1 on the head for use; when the smart device 1 is not used, the headband 200 can be folded to conveniently accommodate the smart device 1, thereby facilitating the use of the user. In further embodiments, the headband 200 is removably connected to the smart device 1.

When the intelligent component 100 works, each electronic component of the intelligent component 100 generates heat, so that the intelligent component 100 forms a heat generating part of the intelligent device 1. The heating of the electronic components may slow the operation speed of the intelligent device 100, and may even cause image and/or sound delay, which may result in poor user experience. For example, for AR glasses, the temperature of the smart component 100 may reach 25 ℃ to 60 ℃, e.g., 30 ℃ to 45 ℃, and further e.g., 40 ℃ while it is operating. To this end, the headband 200 may be configured to include a body 201, on which the elastic metal 300 is disposed on the body 201. The resilient metal member 300 is thermally connected to the smart component 100 of the smart device 1. In this way, the smart component 100 can not only dissipate heat to the surrounding environment by itself, but also the heat generated by the smart component 100 can be transferred to the elastic metal member 300 on the head band to assist in heat dissipation, which is equivalent to increasing the heat dissipation area of the smart component 100. Therefore, the headband 200 with the elastic metal piece 300 can greatly improve the heat dissipation capability of the smart component 100, and further improve the use feeling of the user using the smart device 1. In addition, the elastic metal member 300 forms at least one folding region of the headband 200, thereby facilitating the folding and storage of the headband 200.

In one embodiment, the resilient metal member 300 is configured as a resilient metal sheet 301. The elastic metal sheet 301 has good heat transfer and dissipation performance, thereby helping to dissipate heat of the smart component 100. In addition, the elastic metal sheet 301 is also easier to bend and has good elasticity due to the smaller thickness, which helps to stably wear the smart device 1 on the head, so that the user can see more stable images, thereby further improving the use experience. In one embodiment, the resilient metal sheet 301 is a manganese steel spring. In another embodiment, the elastic metal sheet 301 may also be a TiNi alloy shrapnel. The elasticity of the TiNi alloy spring is good, which facilitates the folding and storage of the headband 200. Especially, when the smart component 100 is operated, the elasticity of the TiNi alloy elastic sheet is very good, so that the bending range of the headband 200 is larger, and the headband is not easily damaged, which is helpful for adapting to the head sizes of different wearers. In other embodiments, the surface of the elastic metal sheet 301 has a protective layer, which is not described herein.

In other embodiments, the thickness of the elastic metal sheet body 301 may be greater than or equal to 0.1mm and less than or equal to 3.5mm, preferably greater than or equal to 0.3mm and less than or equal to 1.2mm, and more preferably 0.8 mm. The inventor finds that the elastic metal sheet 301 with such a thickness is light and thin, not only has good heat dissipation capability, but also has light weight and good elasticity, which helps to reduce the weight of the smart device 1, and the smart device 1 is more stably worn.

As shown in fig. 2, the resilient metal member 300 is disposed within the body 201. In this way, the elastic metal member 300 is not seen from the outside, thereby improving the aesthetic appearance of the smart device 1. In a preferred embodiment, a plurality of heat dissipation holes 310 (shown in fig. 1) extending to the resilient metal member 300 are provided on the body 201. The heat dissipation holes help to improve the heat dissipation capability of the elastic metal member 300, and the aesthetic property of the smart device 1 is not affected.

In one embodiment, as shown in fig. 3, a receiving groove 202 is formed in the body 201, and the resilient metal member 300 is mounted in the receiving groove 202. More preferably, the elastic metal member 300 and the body 201 are fixedly connected together by a screw, so that the elastic metal member 300 is arranged in the body 201.

In a specific embodiment, for the elastic metal sheet body 301, a screw hole is preset on the elastic metal sheet body 301, and a screw hole is correspondingly preset on the body 201, after the elastic metal sheet body 301 is installed in the accommodation groove 202, the screw hole on the elastic metal sheet body 301 is aligned with the screw hole on the body 201, and then a screw is installed in the two screw holes, thereby fixing the elastic metal sheet body 301 in the body 201.

In another specific embodiment, as shown in fig. 4, two receiving cavities 204 are spaced apart from each other on the body 201, and a groove 205 is formed between the two receiving cavities 204. The receiving cavity 204 and the groove 205 together form a receiving groove of the body 201. The body 201 also includes a cover plate (not shown) that fits into the recess 205. The two ends of the elastic metal sheet 301 are inserted into the two receiving cavities 204 respectively (as shown by the dotted lines in fig. 4), and are located in the groove 205 integrally. The cover plate is detachably mounted in the groove 205 and covers the elastic metal sheet body 301, so that the elastic metal sheet body 301 is disposed in the body 201.

In another embodiment, the body is a plastic part, so that the elastic metal sheet 301 can be directly fixed and arranged in the body 201 by injection molding.

A signal line 210 is also provided in the headband 200 of the smart device 1 to enable data transmission. As shown in fig. 3, the signal line 210 extends across the resilient metal member 300 in a fixed attachment manner. The planar elastic metal sheet body 301 is more advantageous for fixing the signal line 210. In the embodiment shown in fig. 4, the signal line 210 may also extend across the elastic metal sheet 301 in a fixed attachment manner. For example, the signal line 210 may be fixedly attached to the elastic metal sheet body 301 by bonding or by forming an extension groove on the surface of the elastic metal sheet body 301. The inventors have found that the elastic metal sheet body 301 has a large bending radius (for example, a bending radius of 2mm to 100mm, preferably 1.5mm to 2.5mm, and more preferably 1.8mm) when housing the headband 200. Therefore, when the elastic metal sheet body 301 is bent, the signal line 210 fixedly attached to the elastic metal sheet body 301 can be bent with a larger bending radius in compliance with the bending of the elastic metal sheet body 301, so that the probability of accidental breakage of the signal line 210 is reduced, and the service life of the intelligent device 1 is prolonged.

Fig. 5 schematically shows the whole of glasses 6 for augmented reality according to another embodiment of the present invention. The glasses 6 are similar to the smart device 1 described above, and only the differences between the two are described here. As shown in fig. 6, the eyeglasses 6 include an eyeglass frame 600 and temples 700 connected to the eyeglass frame 600. The smart component 100 as described above is provided on the eyeglass frame 600, and the elastic metal sheet body 701 (shown in fig. 6 in a cut-away form of the temple 700) is provided on the temple 700. The resilient metal sheet 701 forms a fold of the temple 700. The elastic metal sheet 701 is the same as the elastic metal sheet 301, and thus has good heat transfer and heat dissipation performance, good elasticity and a large bending radius. In this way, the conventional mechanical axis for folding the temple 700 is eliminated from the eyeglasses 6, thereby greatly reducing the number of parts of the eyeglasses 6 and reducing the difficulty and cost of manufacturing the eyeglasses 6. In another embodiment, the elastic metal sheet 701 may further include a protection layer on the surface of the elastic metal sheet 701, which is not described herein again.

In one embodiment, the flexible metal sheet 701 is thermally coupled to the smart component 100. Thus, when the glasses 6 are used, the heat generated by the intelligent component 100 can be dissipated to the surrounding environment through the intelligent component, and the heat can be dissipated by the elastic metal sheet 702 in the glasses legs 700, so that the heat dissipation capability of the glasses 6 or the intelligent component 100 is improved, and the use feeling of the user using the glasses 6 is further improved. In this case, the elastic metal sheet body 701 also serves as a heat radiating member of the eyeglasses 6. It should be understood that "the elastic metal sheet 701 is thermally connected to the smart component 100" means that the elastic metal sheet 701 is directly connected to the smart component 100, and may also be indirectly connected through a heat transfer member. In one embodiment, the eyeglass frame 600 is made of aluminum or aluminum alloy, and the flexible metal sheet 701 is indirectly connected to the smart component 100 through the eyeglass frame 600. Aluminum or aluminum alloy has good heat dissipation performance, and the heat transfer coefficient is higher moreover, helps transferring the heat that intelligent component 100 produced to elastic metal sheet 701 fast to the heat-sinking capability of glasses 6 or intelligent component 100 has further been improved. In addition, the lower density of aluminum or aluminum alloy contributes to a reduction in the weight of the eyeglasses 6, which also contributes to an improvement in the user experience of using the eyeglasses 6.

Preferably, the resilient metal sheet 701 is located in the 1/3 area of the temple 700 that is connected to the frame 600. The inventors have found that with this configuration, the elastic metal sheet body 701 does not contact the wearer's face when the user wears the eyeglasses 6, which avoids the discomfort of the wearer's face caused by the elastic metal sheet body 701 having a high temperature.

Preferably, in the folded state of the elastic metal sheet body 701, the cross section of the elastic metal sheet body 701 is a straight bar shape along the vertical direction (as shown in fig. 7); in the stretched state of the elastic metal sheet body 701, the cross section of the elastic metal sheet body 701 is an arc shape in the vertical direction, and the arc shape protrudes toward the inner side of the temple 700 (as shown in fig. 6). In the eyeglasses 6 using the elastic metal sheet body 701 having such a structure, when the eyeglasses 6 are used, the temple 700 is opened until the elastic metal sheet body 701 is stretched. The inventors have found that the curved cross-section of the resilient metal sheet 701 in the stretched state lends itself to good stiffness, thus maintaining the temple 700 in the open state for the user to wear the eyeglasses 6. When the eyeglasses 6 are stored, a force is applied to the temple 700 so that the elastic metal sheet 701 reaches the folded state, and the temple 700 is thus folded, whereby the eyeglasses 6 can be stored. The inventors have found that the cross section of the straight strip shape in the folded state of the elastic metal sheet body 701 enables it to be stably folded, which facilitates storage by a user.

In addition, the temple 700 further includes a body 710, a receiving groove 711 is formed in the body 710, and the elastic metal sheet 701 is mounted in the receiving groove 711. The elastic metal sheet 701 may also be fixedly connected with the body 710 by screws 712. The body 710 is provided with a plurality of heat dissipation holes 713 extending to the elastic metal sheet body 701. A signal wire 714 is also disposed in the temple 700, and the signal wire 714 extends over the resilient metal sheet 701 in a fixed attachment manner. These features are similar to those described above and will not be described further herein.

It should be understood that in the present application, the smart component 100 may include an image component, such that when using the smart device 1, a user may wear the headband 200 on his head and place the smart component 100 in front of his eyes, so that the user can see the image generated by the smart component 100. The smart component 100 can be imaged by virtual reality techniques, including but not limited to AR techniques, VR techniques, and MR techniques. In another embodiment, the smart component 100 may also include an audio component to generate sound that is adapted to the image. In addition, the smart component 100 may also be a separate audio component.
