Description

[Technical Field]

[0001] [CROSS-REFERENCE TO RELATED APPLICATIONS] This application claims priority to a patent application filed with the State Intellectual Property Office of China on May 10, 2021, bearing application number 202110505110.3 and titled "Anti-light interference infrared-transmitting housing and infrared positioning handle."

[0002] FIELD OF THE INVENTION This application relates to the field of infrared positioning handles, and more particularly to an infrared transparent housing and an infrared positioning handle that prevents light interference. [Background technology]

[0003] As society advances and technology develops, the application of artificial reality (AI) systems in fields such as computer games, health and safety, industry, and education has become increasingly widespread. For example, AI systems have been incorporated into mobile devices, game consoles, personal computers, movie theaters, and theme parks. Generally, AI is a form of adjusting reality in some manner before it is presented to a user, and may include, for example, virtual reality (VR), augmented reality (AR), mixed reality (MR), or any combination and / or derivative thereof. A typical AI system presents and displays content to one or more users using one or more devices to interact with the system. Illustratively, an AI system may include a head-mounted display (HMD) worn by a user and a positioning handle, configured to output AI-related content to the user.

[0004] Conventional positioning handles generally have an infrared-transmitting plastic material covering the outside of the infrared lamp. Because no external light-blocking element is added, this method makes it impossible to use the positioning handle indoors or outdoors in strong light, limiting its range of application. To solve this problem, a full light-blocking cover is usually placed directly on the outside of the infrared-transmitting plastic material of the positioning handle. However, because precise or firm positioning between the light-blocking cover and the infrared-transmitting plastic material cannot be achieved, the light-blocking cover is likely to rattle on the outside of the positioning handle during use, which affects the use of the infrared lamp and the user experience. Summary of the Invention

[0005] The present application has been made in consideration of the above-mentioned problems, and its purpose is to provide an infrared-transmitting housing and an infrared positioning handle that prevent light interference and solve the problem that conventional positioning handles tend to have rattle between the light-shielding cover and the infrared-transmitting member, making it difficult to accurately position the light-transmitting position of the infrared lamp and affecting the user experience.

[0008] In addition, as an optional technical solution, the anti-collision protrusion is circular, oval or rectangular.

[0009] In addition, as an alternative technical solution, the first housing is an infrared-transmitting plastic member, and the second housing is a light-shielding silicone member or a light-shielding plastic member.

[0021] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to describe the infrared-transmitting housing and infrared positioning handle according to the present invention in detail, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] FIG. 1 shows a schematic structure of an infrared-transmitting housing for preventing optical interference according to an embodiment of the present invention.

[0023] As shown in FIG. 1, an infrared-transmitting housing for preventing light interference (abbreviated as infrared-transmitting housing) according to an embodiment of the present application comprises a first housing 2 and a second housing 3 provided on the outside of the first housing 2, the first housing 2 being an infrared-transmitting member, the second housing 3 being a light-blocking member, a via hole 4 being formed in the second housing 3 corresponding to the position of an infrared lamp of an external device, the infrared-transmitting housing being provided to cover the outside of the infrared lamp, and the first housing 2 and the second housing 3 being integrally molded by double injection molding, i.e., the first housing 2 and the second housing 3 have an integrally molded structure, and the two housings will not shift relative to each other.

[0024] Furthermore, to prevent an external device from colliding with the infrared-transparent housing during use, a plurality of collision prevention protrusions 5 may be further provided on the surface of the second housing 3. The position of the collision prevention protrusions 5 can be set according to the shape or structure of the infrared-transparent housing, and for example, the collision prevention protrusions 5 can be installed so as to be evenly distributed so as to surround the outside of the second housing 3, or the collision prevention protrusions 5 can be installed in positions where collisions are likely to occur.

[0025] For example, the anti-collision protrusions 5 may have various shapes such as a circle, an oval, a strip, etc. The anti-collision protrusions 5 may be integrally molded with the second housing 3, that is, a plurality of anti-collision protrusions 5 may be formed directly on the outside of the second housing 3 by double injection molding.

[0026] In one embodiment of the present application, the first housing 2 may be made of an infrared-transmitting plastic material, and the second housing 3 may be made of a structural material with a light-blocking function, such as a light-blocking silicone material or a light-blocking plastic material. The first housing 2 and the second housing 3 are integrally molded by double-injection molding. Here, double-injection molding can be used to manufacture thermoplastic materials of two different compositions, and the first housing 2 and the second housing 3, which are made of different materials, can be injection-molded as an integral structure.

[0027] To ensure accurate positioning between the infrared transparent housing and the external device, a positioning structure may be provided on the inside of the first housing 2, away from the second housing 3. The position at which the positioning structure is provided matches the positioning portion of the external device where the infrared lamp will be installed. Ensuring that the positioning structure and the positioning portion of the external device are compatible during the assembly process of the infrared transparent housing ensures that the positions of the via holes 4 and the infrared lamps correspond to each other, simplifying the installation of the infrared transparent housing and ensuring the positioning accuracy of the infrared transparent housing.

[0028] Specifically, FIG. 2 shows a schematic structure of a first housing according to an embodiment of the present application.

[0029] As shown in Figure 2, in the double injection process, the first housing 2 is an infrared-transparent material, and four protruding cylindrical positioning structures 6 are installed inside it. The positions and number of the positioning structures 6 may be set to match the positioning parts of the external device. As with the collision prevention protrusions, the positioning structures of the present application may be installed as an integrally molded structure with the first housing 2.

[0030] Furthermore, the shape, size and location of the positioning structure 6 can all be installed and adjusted according to the requirements of external installation, and is not limited to the specific cylindrical structure shown in the drawings, but may be multiple positioning structures evenly distributed around the inside of the first housing 2.

[0031] In one embodiment of the present application, via holes are provided in the second housing and extend through the second housing. The positions and number of the via holes correspond to the positions and number of the infrared lamps, respectively. The size of the via holes can be adjusted according to the size and requirements of the infrared lamps. After the infrared-transmitting housing and the external device are assembled, the corresponding via holes and the first housing 2 transmit the light beams of the infrared lamps, while other positions are shielded by the second housing, preventing external light from affecting the positioning of the infrared lamps or the infrared rays. Not only is the shielding position accurate, but there is also no play between the housings, and the positioning requirements of the external device are met.

[0032] In accordance with the above-mentioned anti-light interference infrared transparent housing, the present application further provides an infrared positioning handle. That is, the above-mentioned external device can be other devices or equipment that require the installation of an infrared lamp, such as an infrared positioning handle. Specifically, Figure 3 shows a schematic structure of an infrared positioning handle according to an embodiment of the present application.

[0033] As shown in FIG. 3, the infrared positioning handle according to the embodiment of the present application comprises a handle body 1, an inner housing (not shown) and an outer housing (not shown) provided at the upper end of the handle body 1, and an infrared lamp ring provided between the inner housing and the outer housing. An infrared-transparent housing is fitted into the outer side of the outer housing at a position corresponding to the infrared lamp ring, and the infrared-transparent housing is the above-mentioned infrared-transparent housing that prevents light interference.

[0034] Here, the positions of the via holes in the infrared-transparent housing correspond one-to-one to the positions of the infrared lamps in the infrared lamp ring. The infrared-transparent housing is fixed to the outer wall of the outer housing by a positioning member (i.e., a positioning structure in the embodiment of the infrared-transparent housing for preventing optical interference) located inside the first housing.

[0035] The embodiment of the infrared positioning handle can be referred to the description of the embodiment of the anti-light interference infrared transparent housing, so no further description will be given here.

[0036] The above-mentioned light interference-preventing infrared-transparent housing and infrared positioning handle of the present application use a second housing to shield non-infrared portions of external equipment, preventing external light from affecting the infrared lamp or infrared positioning. The positioning of the shielding portion is accurate and the housing does not rattle. Furthermore, the provision of localized anti-collision protrusions effectively prevents damage to the equipment due to accidental collisions. The assembly of the infrared-transparent housing is simple and convenient, with high positioning accuracy.

[0037] The above describes the light interference-preventing infrared-transmitting housing and infrared positioning handle according to the present application by way of example with reference to the accompanying drawings. However, as will be understood by those skilled in the art, various modifications can be made to the light interference-preventing infrared-transmitting housing and infrared positioning handle proposed by the present application without departing from the scope of the present application. Therefore, the scope of protection of the present application should be determined by the content of the appended claims.
