[0024] The following will describe in detail the solutions provided by the embodiments of the present disclosure in conjunction with the accompanying drawings.
[0025] See the accompanying drawings Figures 1 to 7As shown, the present disclosure provides a head-mounted device, including a device main body 1 and a face-attaching component 2. The head-mounted device has a switchable first state and second state. In the first state, the distance between the device main body 1 and the face-attaching component 2 is less than that in the second state. The device main body 1 has a straight tube 11 extending towards the face-attaching component 2. A heart rate detection component (not labeled in the figure) and a position adjustment mechanism (not labeled in the figure) at one end of the heart rate detection component away from the face-attaching component 2 are installed in the straight tube 11. It can be understood that the detection end of the heart rate detection component can contact the part to be detected of the user (such as the forehead of the user). The position adjustment mechanism has a first position corresponding to the first state and a second position corresponding to the second state. The distance between the position adjustment mechanism and the face-attaching component 2 in the first position is greater than that in the second position. The switching of the position adjustment mechanism between the first position and the second position can adjust the position of the heart rate detection component.
[0026] In this technical solution, the position adjustment mechanism has a first position that is farther from the face-attaching component 2 and a second position that is closer in the axial direction of the straight tube 11. Thus, it can achieve matching with the state switching of the head-mounted device through the switching change of its own position, realize the position change of the heart rate detection component, ensure the relative stability of the position of the heart rate detection component and the part to be detected of the user, and effectively prevent the phenomenon that the heart rate detection component is not tightly attached or leaves marks due to excessive stress caused by the size difference resulting from the state change of the head-mounted device. In some embodiments, the detected heart rate can be displayed on the display screen in the head-mounted device, and the user can see the heart rate without removing the head-mounted device. For example, the head-mounted device can be a head-mounted extended reality device, and the detected heart rate can be displayed in the extended reality space displayed by the head-mounted extended reality device.
[0027] In a specific embodiment, in the first state, the device main body 1 is in contact connection with the face-attaching component 2. In the second state, a first bracket 3 is clamped between the device main body 1 and the face-attaching component 2. At the same time, when the first bracket 3 is assembled to the head-mounted device, the position adjustment mechanism can be in the second position at this time, and when the first bracket 3 is not assembled, the position adjustment mechanism is in the first position. That is, the first bracket 3 in the present disclosure is an optional component. When the user wears glasses, the first bracket 3 is assembled between the device main body 1 and the face-attaching component 2 to achieve the aforementioned first state to ensure the comfort of the user. When the user does not wear glasses, the first bracket 3 can be optionally not assembled, so that the head-mounted device of the present disclosure takes into account the use comfort of the head-mounted device for both glasses-wearing users (such as users wearing myopia glasses) and non-glasses-wearing users.
[0028] The aforementioned face - fitting component 2 is preferably made of a relatively soft material, such as sponge, to enhance the comfort when contacting the user.
[0029] Referring to Figure 1 , Figure 2 and Figure 5 As a specific implementation form, the position - adjusting mechanism includes a position - adjusting member 51 and an elastic member 52 that applies elastic pressure to the side of the position - adjusting member 51 away from the face - fitting component 2. There are a plurality of positioning bars 111 arranged at intervals along the circumferential direction on the inner cylindrical wall of the straight cylinder member 11. A guiding groove 112 extending along the axial direction of the straight cylinder member 11 is formed between two circumferentially adjacent positioning bars 111 (as shown in Figure 7 ). A positioning slot 113 is formed at the end of the positioning bar 111 away from the face - fitting component 2. The position - adjusting member 51 has a plurality of ribs 511 extending along the axial direction of the straight cylinder member 11. A slope 512 is formed at the end of each rib 511 facing the face - fitting component 2 (as shown in Figure 6 ). When the position - adjusting mechanism is in the first position, each slope 512 abuts against each positioning slot 113 respectively. At this time, the inclination angle of each slope 512 is the same as the inclination angle of the bottom of the positioning slot 113, so that the state of the position - adjusting member 51 in the first position is more stable and reliable. As described above, at this time, the end of the heart - rate detection component away from the face - fitting component 2 does not abut against the slope of the rib 511, but it abuts against a part of the side of the position - adjusting member 51 close to the face - fitting component 2. Thus, in the first position, the elastic member 52 can apply an elastic force to the heart - rate detection component in the axial direction, so as to realize the adaptive adjustment of the axial position of the heart - rate detection component. The range of the adaptive adjustment in this position is limited by the axial depth of the aforementioned positioning slot 113. When the position - adjusting mechanism is in the second position, each slope 512 slides into each guiding groove 112 respectively. At this time, each slope 512 abuts against the corresponding end - face structure of the heart - rate detection component. And under the elastic pressure of the elastic member 52, the position - adjusting member 51 slides in the guiding groove 112 and is closer to the side of the face - fitting component 2 compared with the positioning slot 113, so that after the first bracket 3 is assembled on the head - mounted device, it forces the heart - rate detection component to move closer to the face - fitting component 2, thereby realizing the position compensation after the assembly of the first bracket 3. In this position, the elastic member 52 can also apply an elastic force to the heart - rate detection component in the axial direction, so as to realize the adaptive adjustment of the axial position of the heart - rate detection component.
[0030] In an alternative embodiment, the heart rate detection component includes a second bracket 41. A serrated groove 411 is formed at one end of the second bracket 41 away from the face-attaching component 2. The bottom inclination angle of each serrated groove 411 matches each slope 512, and each serrated groove 411 and each slope 512 can be engaged respectively, so that the position adjusting member 51 can switch between a first position and a second position when a first axial force is applied to the heart rate detection component. The first axial force is an axial force applied from the side of the face-attaching component 2 to the side of the device main body 1. Specifically, the bottom inclination angle of the aforementioned serrated groove 411 is inclined successively along the circumferential direction of the second bracket 41. After applying the aforementioned first axial force to the end (the end close to the face-attaching component 2) of the heart rate detection component, the heart rate detection component drives the position adjusting member 51 that is matched and engaged with it to move axially closer to the side of the device main body 1. Due to the meshing relationship and size relationship between the serrated groove 411 and the slope 512 (the groove depth of the serrated groove 411 is greater than the axial height of the slope 512), the position adjusting member 51 will rotate a certain angle around its geometric central axis during the axial movement. Thus, after the first axial force is removed, under the action of the elastic member 52, the heart rate detection component and the position adjusting member 51 are axially displaced and reset in the opposite direction. Since the position adjusting member 51 rotates, it will abut against the aforementioned positioning card slot 113 during the reset process, while the axial displacement of the heart rate detection component is not restricted by the positioning card slot 113. Thus, the switching of the position adjusting member 51 from the second position to the first position is realized, and the switching principle from the first position to the second position is the same and will not be elaborated. It can be seen that in this technical solution, only by applying an axial force to the end of the heart rate detection component, the position switching of the position adjusting member 51 can be realized after removing the axial force, and the switching control is very simple and convenient.
[0031] Further referring to Figure 5 As shown, the second bracket 41 is of a cylindrical structure. A plurality of guide ribs 412 are provided on the outer circumferential wall of the second bracket 41. Each guide rib 412 is inserted into each guide groove 112. Since each guide rib 412 is respectively inserted into each guide groove 112, it can effectively prevent the circumferential rotation of the heart rate detection component, ensure the position reliability of the detection head part, and also ensure the smooth movement during the application of the first axial force. The cylindrical opening of the straight cylinder 11 facing the face-attaching component 2 has a flange (not labeled in the figure) extending radially inward. The flange can be an annular structure, which can limit the axial displacement of the second bracket 41 and prevent the heart rate detection component from popping out of the straight cylinder 11.
[0032] In some embodiments, a heart rate module 42 is provided inside the second bracket 41. The heart rate module 42 has a detection component. One end of the second bracket 41 facing the face-attaching component 2 is connected with a first cover body 43. The first cover body 43 has a light-transmitting area 431 and a light-shielding area 432. The detection component is located on the side of the first cover body 43 close to the second bracket 41 and is arranged corresponding to the light-transmitting area. The first cover body 43 seals one end of the heart rate detection component to physically protect the detection component and improve the waterproof and dustproof capabilities of the corresponding components. The aforementioned detection component specifically includes, for example, a heart rate detection light-emitting LED, a receiving sensor, and a light-shielding foam or silica gel. The light-shielding foam or silica gel is used to separate the light of the light-emitting LED and the receiving sensor and form a light guide area. At the same time, the heart rate module 42 is electrically connected to the control main board of the corresponding head-mounted device through its FPC (flexible printed circuit board), and can freely extend or shorten according to the change of position to ensure the smoothness of position switching. The FPC is adhered to the inner wall of the second bracket 41.
[0033] As shown in FIG. 2, a second cover body 44 is connected to the mouth of the straight tube member 11 away from the face-attaching component 2. For example, the connection between the second cover body 44 and the straight tube member 11 can be achieved by bonding. The elastic member 52 is clamped between the second cover body 44 and the position adjusting member 51. The second cover body 44 provides a reliable support point for the elastic pressure of the elastic member 52. The corresponding end of the elastic member 52 can be bonded to the inner side surface of the second cover body 44.
[0034] In a specific embodiment, the elastic member 52 is a helical spring. The second cover body 44 has a through hole 441. Part of the heart rate module 42 is arranged to pass through the central hole of the helical spring and is inserted into the through hole 441. Specifically, the aforementioned FPC passes through the helical spring and the second cover body 44 in sequence and then extends out to be electrically connected to the main board of the head-mounted device, simplifying the circuit connection structure. In another preferred technical solution, the central through hole of the position adjusting member 51 has a mounting hole section (not labeled in the figure), and one end of the helical spring is embedded in the mounting hole section, so that the position between the position adjusting member 51 and the helical spring ring is more reliable.
[0035] The face-attaching component 2 and / or the first bracket 3 are / is constructed with a support through hole 6 for inserting the straight tube member 11 to support the cantilever-structured straight tube member 11 and simultaneously realize the assembly positioning and guiding functions of the face-attaching component 2, the device body 1, and the first bracket 3; the straight tube member 11 and the device body 1 are integrally formed, for example, by one-piece injection molding, to simplify the assembly between the device body 1 and the straight tube member 11.
[0036] The following further elaborates on the position adjustment principle of the heart rate detection component in the head-mounted device of the present disclosure:
[0037] In the initial state (with the first bracket 3 by default), to ensure that the appearance part of the heart rate detection component (i.e., the aforementioned first cover 43) is flush with the face-contact foam (i.e., the aforementioned face-contact component 2, the same below), this heart rate detection component can be pressed down so that the rib position (i.e., the aforementioned rib 511, the same below) on the adjustment mechanism (i.e., the aforementioned position adjustment part 51, the same below) is in the guiding groove 112 part of the accommodation cavity of the head-mounted rear shell (i.e., the aforementioned device main body 1, the same below); the extended part of the heart rate detection component is relatively long, and at the same time, the adjustment mechanism can be finely adjusted with the compression amount of the foam by the user's forehead under the action of the spring (i.e., the aforementioned elastic part 52, the same below).
[0038] When the first bracket 3 is not needed, press down the right end of the entire heart rate detection component ( Figure 2 in the shown orientation), and the adjustment mechanism will move left along the track (i.e., the aforementioned guiding groove 112) under the push of the sawtooth groove 411 until the contact part exceeds the shift guiding mechanism (i.e., the end of the aforementioned positioning bar 111, the same below) of the accommodation cavity of the head-mounted rear shell. At this time, under the action of the spring, the adjustment mechanism will rotate a certain angle and enter the positioning card slot 113. The rib position of the adjustment mechanism contacts the head-mounted rear shell. At this time, the stroke of the entire heart rate detection component has been shortened, ensuring that the heart rate detection component is flush with the face-contact foam, and at the same time, fine adjustment can also be performed;
[0039] When the first bracket 3 is needed again, press the heart rate detection component again. The sawtooth groove 411 contacts the adjustment mechanism, so that the rib position of the adjustment mechanism exceeds the left end of the positioning card slot 113. After releasing the heart rate detection component, under the combined action of the spring and the sawtooth groove 411, the adjustment mechanism rotates a certain angle and enters the guiding groove 112, returning to the second position (with the first bracket 3) and restoring the state.
[0040] In some embodiments, the present disclosure also proposes an extended reality device, which includes the head-mounted device proposed in any one of the present disclosures. The head-mounted device itself can be an extended reality device. The extended reality device can be a virtual reality device, an augmented reality device, or a mixed reality device. In some embodiments, as Figure 8 shown, users can, through extended reality devices such as a head-mounted display (HMD), etc., perform social interactions, entertainment, learning, work, telecommuting, creating UGC (User Generated Content), etc. Users can enter the extended reality space through extended reality devices such as head-mounted glasses and head-mounted helmets, and control their virtual characters (Avatars) in the extended reality space to perform social interactions, entertainment, learning, telecommuting, etc. with virtual characters controlled by other users.
[0041] In one embodiment, in the extended reality space, a user can implement relevant interaction operations through a controller, which can be a handle. For example, the user can perform relevant operation controls by operating the buttons on the handle. Of course, in other embodiments, it is also possible not to use a controller but to use gestures, voice, or multimodal control methods to control the target object in the extended reality device.
[0042] The extended reality devices described in the embodiments of the present disclosure may include, but are not limited to, the following types:
[0043] Computer-side extended reality devices perform relevant calculations and data output for extended reality functions using a computer. The external computer-side extended reality device utilizes the data output by the computer to achieve the effect of extended reality.
[0044] Mobile extended reality devices support setting a mobile terminal (such as a smartphone) in various ways (such as a head-mounted display with a dedicated card slot). Through a wired or wireless connection with the mobile terminal, the mobile terminal performs relevant calculations for extended reality functions and outputs data to the mobile extended reality device. For example, watch extended reality videos through an APP on the mobile terminal.
[0045] All-in-one extended reality devices are equipped with a processor for performing relevant calculations for extended reality functions, and thus have independent extended reality input and output functions. They do not need to be connected to a computer or a mobile terminal, and have a high degree of freedom of use.
[0046] Of course, the implementation form of the extended reality device is not limited to this, and it can be further miniaturized or enlarged according to needs.
[0047] The extended reality device is provided with a sensor for attitude detection (such as a nine-axis sensor) to detect the attitude change of the extended reality device in real time. If a user wears the extended reality device, when the user's head attitude changes, the real-time attitude of the head will be transmitted to the processor, and based on this, the fixation point of the user's line of sight in the extended reality space environment is calculated. According to the fixation point, the image within the user's viewing range (i.e., the virtual field of view) in the three-dimensional model of the extended reality space environment is calculated and displayed on the display screen, giving people an immersive experience as if they were watching in a real environment.
