DETAILED DESCRIPTION

[0029] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, but cannot be understood as limiting the present application.

[0030] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0031] The embodiments of the present application can be applied to various application scenarios such as extended reality (eXtended Reality, XR), such as virtual reality (VR), augmented reality (AR), and mixed reality (MR).

[0032] Taking Virtual Reality (VR) as an example, VR is a technology for creating and experiencing a virtual world. It is a technology based on multi-source information (such as visual perception, auditory perception, tactile perception, motion perception, and even taste perception, olfactory perception, etc.) to achieve a fusion of virtual environments, interactive three-dimensional dynamic vision and simulation of entity behaviors, allowing users to immerse themselves in a simulated virtual reality environment, and realize applications in a variety of virtual environments such as maps, games, videos, education, medical care, simulation, collaborative training, sales, assisted manufacturing, maintenance and repair, etc.

[0033] The terminal that realizes the virtual reality effect is generally called VR device, which can usually be provided in the form of a head-mounted device. The head-mounted device generally includes: a host, a face-mounted foam and a fixing part. The face-mounted foam is connected to one side of the host to contact the user's face. The fixing part is used to fix the host to the user's face so that the two display modules in the host are respectively opposite to the two eyes of the user, so that the user can watch the virtual reality scene. However, the head-mounted device in the related art has a relatively single overall function.

[0034] In order to overcome the above-mentioned problems, an embodiment of the present application provides a heart rate detection device for a head-mounted device, by setting a first mounting hole in the area corresponding to the facial contact structure and the user's forehead, and installing the heart rate sensor in the first mounting hole through a mounting bracket, so that the heart rate sensor close to the user's forehead can detect the user's heart rate, thereby enriching the function of the head-mounted device with a heart rate detection device.

[0035] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0036] For ease of description, in this embodiment, when the head mounted device is worn on the user's head, the direction of the head mounted device toward the user is referred to as the front, the direction toward the ground is referred to as the bottom, and the up and down direction is referred to as the vertical direction.

[0037] Please refer to Figures 1 to 3The embodiment of the present application provides a heart rate detection device 1 for a head-mounted device, including: a facial contact structure 11, the front side of the facial contact structure 11 is used to abut against the user's face, and a first mounting hole 11a is provided in the facial contact structure 11, and the first mounting hole 11a is located in the area of ​​the facial contact structure 11 opposite to the user's forehead; a mounting bracket 12, the mounting bracket 12 is arranged in the first mounting hole 11a of the facial contact structure; a heart rate sensor 13, the heart rate sensor 13 is installed on the mounting bracket 12, and the detection end of the heart rate sensor 13 is arranged toward the front side of the facial contact structure 11, and the heart rate sensor 13 is also electrically connected to the processor of the head-mounted device.

[0038] The facial contact structure 11 is used to be connected to the front side of the host 3 of the head-mounted device so as to be in direct contact with the user's face when the user wears the head-mounted device, thereby improving the wearing comfort of the user.

[0039] Exemplarily, the facial contact structure 11 may be made of face-fitting foam, and may specifically include: a foam body 111 and a foam bracket 112, wherein the foam body 111 is fixed to the foam bracket 112, and the foam bracket 112 is connected to the host 3 of the head-mounted device. The foam body 111 may be fixedly connected to the foam bracket 112 by bonding or snapping. The foam bracket 112 may be connected to the host 3 of the head-mounted device by fastening or snapping. In other embodiments, the facial contact structure 11 may also be made of other materials such as silicone.

[0040] In some embodiments, the facial contact structure 11 is provided with a first mounting hole 11a for mounting the heart rate sensor 13. The first mounting hole 11a can be disposed in an upper and relatively central area of ​​the facial contact structure 11. For example, the vertical center line of the first mounting hole 11a can coincide with the vertical center line of the facial contact structure 11, or have a preset spacing. In this way, the heart rate sensor 13 can be closely attached to the forehead of the user where capillaries are relatively abundant, thereby improving the accuracy of heart rate detection.

[0041] Exemplarily, the first mounting hole 11a is arranged through in the front-to-back direction. In some examples, the first mounting hole 11a can be arranged on the foam body 111. In other examples, the foam body 111 is provided with a through hole, the facial contact structure support 112 is provided with a mounting seat, and the first mounting hole 11a is arranged on the mounting seat.

[0042] In other embodiments, the first mounting hole 11 a may also be installed at the upper portion of the face contact structure 11 and in a relatively left area or a relatively right area.

[0043] The heart rate sensor 13 can be installed in the first mounting hole 11a through the mounting bracket 12. The heart rate sensor 13 can be fixed to the first end of the mounting bracket 12. In some examples, the heart rate sensor 13 is fixed to the first end of the mounting bracket 12 by plugging, clamping or bonding.

[0044] In some embodiments, Figure 3 As shown, the mounting bracket 12 can be mounted in the first mounting hole 11a by interference fit, bonding, or snap-on connection. The elasticity of the foam body in the facial contact structure 11 can be used to tightly attach the heart rate sensor 13 to the user's forehead E.

[0045] Please refer to Figures 4 to 6 In other embodiments, the mounting bracket 12 is slidably disposed in the first mounting hole 11a, and an elastic member 14 is disposed in the first mounting hole 11a. The elastic member 14 can be extended and retracted along the axial direction of the first mounting hole 11a, and one end of the elastic member 14 can abut against the mounting bracket 12. The elastic member 14 can push the mounting bracket 12 and the heart rate sensor 13 forward, so that the heart rate sensor 13 can be closely attached to the user's forehead, thereby being able to adapt to the use needs of users with different head shapes. Among them, the elastic member 14 can be a spring or an elastic rubber sleeve.

[0046] When the heart rate detection device 1 is not attached to the user's forehead, the elastic member 14 may be in a compressed state or an original state. Figure 6 As shown, when the heart rate detection device 1 is in a state of being attached to the user's forehead E, the user's forehead E will push backward against the mounting bracket 12 and the heart rate sensor 13 and compress the elastic member 14. Under the action of the elastic potential energy of the elastic member 14, the heart rate sensor 13 is tightly attached to the user's forehead E.

[0047] In some examples, a shaft seat 114 is fixedly disposed in the first mounting hole 11a, and a mounting shaft 113 is also disposed in the first mounting hole 11a, and the mounting shaft 113 is slidably inserted in the center hole of the shaft seat 114. The axial directions of the shaft seat 114 and the mounting shaft 113 may be parallel to the axial direction of the first mounting hole 11a. The shaft seat 114 may be integrally disposed with the foam bracket 112, or the shaft seat 114 may be an independent component and fixed in the first mounting hole 11a.

[0048] The front end of the mounting shaft 113 is fixedly connected to the mounting bracket 12. An elastic member 14 is provided on the outer sleeve of the mounting shaft 113, and the two ends of the elastic member 14 are respectively against the shaft seat 114 and the mounting bracket 12, and the elastic member 14 can push the mounting bracket 12 and the heart rate sensor 13 forward, so that the heart rate sensor 13 can be closely attached to the user's forehead, thereby being able to adapt to the use needs of users with different head shapes.

[0049] Exemplarily, the shaft seat 114 may have a mounting sleeve 1141 and a stop ring 1142 disposed at the front end of the mounting sleeve 1141. The stop ring 1142 may be coaxially disposed with the mounting sleeve 1141, and the diameter of the portion of the center hole of the shaft seat 114 located in the mounting sleeve 1141 is larger than the diameter of the portion of the center hole located in the stop ring 1142. The rear end of the mounting shaft 113 is provided with a flange 1131 extending in its radial direction, the flange 1131 is located in the mounting sleeve 1141, and the outer diameter of the flange 1131 is larger than the diameter of the portion of the center hole located in the stop ring 1142. One end of the elastic member 14 may abut against the second end 1212 of the mounting bracket 12, and the other end of the elastic member may abut against the stop ring 1142 of the shaft seat. Through the above arrangement, the limit ring 1142 can abut against the flange 1131 of the mounting shaft 113 to limit the extreme position of the mounting bracket 12 and the heart rate sensor 13 sliding forward, so as to prevent the mounting bracket 12 and the heart rate sensor 13 from detaching from the hole at the front end of the first mounting hole 11a.

[0050] The rear end of the mounting sleeve 1141 may be provided with a first extension edge, which is extended in a direction away from the central axis of the mounting sleeve 1141, and a shallow groove matching the extension edge is provided on the rear side of the foam body 111 of the face contact structure 11. The specific shape of the first extension edge can be set according to actual needs.

[0051] Exemplarily, the mounting shaft 113 may be stepped, and the mounting shaft 113 has a first shaft section and a second shaft section connected to each other, the first shaft section is connected to the front end of the second shaft section, and the shaft diameter of the first shaft section is smaller than the shaft diameter of the second shaft section. The mounting bracket 12 is fixedly connected to the first shaft section. The elastic member 14 is sleeved outside the second shaft section. The rear end of the mounting shaft 113, that is, the rear end of the second shaft section, is provided with a flange 1131. Among them, the first shaft section, the second shaft section and the flange 1131 of the mounting shaft 113 can be integrally arranged; or, the mounting shaft includes a shaft body and a sleeve, the sleeve is sleeved on the rear end of the shaft body, the part of the shaft body not sleeved with the sleeve constitutes the first shaft section, the part of the shaft body sleeved with the sleeve constitutes the second shaft section, and the rear end of the shaft body is provided with a flange 1131.

[0052] When the heart rate detection device 1 provided in this embodiment is used and is not attached to the forehead of the user, the elastic member 14 can be in a compressed state, and the flange 1131 of the mounting shaft 113 abuts against the limiting ring 1142 of the shaft seat 114; Figure 6As shown, when the heart rate detection device 1 is in a state of being attached to the user's forehead E, the mounting bracket 12 and the heart rate sensor 13 can slide backward in the first mounting hole 11a according to the contour of the user's head, such as the user's forehead, and further compress the elastic member 14. That is, the user's forehead will push backward against the mounting bracket 12 and the heart rate sensor 13 and further compress the elastic member 14. In this way, under the elastic action of the elastic member 14, the detection end of the heart rate sensor 13 can be closely attached to the user's forehead, thereby being able to adapt to the usage needs of users with different head shapes.

[0053] In other embodiments, the mounting shaft 113 and the shaft seat 114 may be fixedly connected, and the mounting bracket 12 may be slidably disposed at the front end of the mounting shaft 113, so that the mounting bracket 12 and the heart rate sensor 13 slide along the axial direction of the mounting shaft 113. The elastic member 14 may be sleeved outside the mounting shaft 113 and abutted between the mounting bracket 12 and the shaft seat 114.

[0054] The heart rate sensor 13 is roughly cylindrical. In some examples, the heart rate sensor 13 can be electrically connected to the processor of the head-mounted device, so that the battery module of the head-mounted device can power the heart rate sensor 13 and enable the heart rate sensor 13 to communicate data with the processor. In other examples, the heart rate sensor 13 can communicate data with the processor by wireless communication, and a battery module for powering the heart rate sensor 13 is provided in the facial contact structure 11.

[0055] After the heart rate information detected by the heart rate sensor 13 is transmitted to the processor, the processor can prompt the user according to the heart rate information, such as displaying it, so that the user can understand his or her heart rate status in time. For example, for users who like fitness, the exercise intensity can be adjusted in a targeted manner through the prompt of the heart rate. In other examples, the processor can also send the heart rate information to other terminals or wearable devices that are connected to the head-mounted device, such as sports watches or mobile phones, so that the user can view it.

[0056] The heart rate detection device 1 provided in this embodiment is used for a head-mounted device, by providing a facial contact structure 11, the facial contact structure 11 faces the front side of the user and is used to abut against the user's face, and a first mounting hole 11a is provided in the facial contact structure 11, and the first mounting hole 11a is located in the area of ​​the facial contact structure 11 opposite to the user's forehead; by providing a mounting bracket 12, the mounting bracket 12 is provided in the first mounting hole 11a of the facial contact structure; by providing a heart rate sensor 13, the heart rate sensor 13 is installed on the mounting bracket 12, and the detection end of the heart rate sensor 13 faces the front side of the facial contact structure 11, and the heart rate sensor 13 is also electrically connected to the processor of the head-mounted device. In this way, when the heart rate detection device 1 is attached to the user's face, the heart rate sensor 13 close to the user's forehead can detect the user's heart rate, thereby enriching the function of the head-mounted device with the heart rate detection device.

[0057] Please refer to Figures 4 to 6 In some embodiments, the mounting bracket 12 includes: a mounting body 121, the mounting body 121 has a first end 1211 and a second end 1212 connected to each other, the first end 1211 is provided with a second mounting hole, the heart rate sensor 13 is located in the second mounting hole, and the second end 1212 is provided with an axial hole, which cooperates with the front end of the mounting shaft 113.

[0058] Exemplarily, the outer diameter of the first end 1211 may be smaller than the outer diameter of the second end 1212, which is beneficial to the compactness of the structure of the heart rate detection device 1. The axial direction of the first end 1211 may have a preset angle with the axial direction of the second end 1212. For example, the first end 1211 of the installation body 121 may be coaxially arranged with the installation shaft 113; the axial direction of the second end 1212 of the installation body 121 is inclined downward relative to the axial direction of the first end 1211.

[0059] In some examples, the mounting body 121 further includes a partition 1213, which is disposed at the connection between the first end 1211 and the second end 1212, and is used to separate the second mounting hole from the shaft hole. The partition 1213 may be an inclined plate, which may be disposed perpendicularly to the axial direction of the second end 1212 of the mounting body 121.

[0060] The mounting bracket 12 is also connected to a light-transmitting lens 16, which blocks the front side of the heart rate sensor 13 and covers at least the opening of the second mounting hole. In this way, the light-transmitting lens 16, the partition 1213 and the first end 1211 can enclose a relatively closed receiving space, and the heart rate sensor 13 is arranged in the space to play a role of sealing and protection.

[0061] The light-transmitting lens 16 can be made of a light-transmitting material for transmitting light emitted by the heart rate sensor 13. The light-transmitting lens 16 can be fixedly connected to the mounting bracket 12 so that the light-transmitting lens 16 can slide along the axial direction of the first mounting hole 11a together with the mounting bracket 12.

[0062] When the heart rate detection device 1 is not attached to the user's forehead, the elastic member 14 may be in a compressed state, and the flange 1131 of the mounting shaft 113 abuts against the limiting ring 1142 of the shaft seat 114; Figure 6 As shown, when the heart rate detection device 1 is in a state of being attached to the user's forehead E, the user's forehead will push backwards against the mounting bracket 12 and the heart rate sensor 13 through the transparent lens 16, and further compress the elastic member 14. Under the action of the elastic potential energy of the elastic member 14, the transparent lens 16 can be tightly attached to the user's forehead E.

[0063] In some examples, the outer periphery of the mounting body 121 is also connected to a first extension portion 122 extending outward, and the side of the first extension portion 122 facing away from the mounting body 121 is also connected to a second extension portion 123, and the second extension portion 123 is folded forward relative to the first extension portion 122, so that the first extension portion 122, the second extension portion 123 and part of the mounting body 121 form a mounting groove 122a.

[0064] The first extension portion 122 may be connected to the outer peripheral surface of the middle portion of the installation body 121, for example, the first extension portion 122 may be connected to the area of ​​the second end portion 1212 close to the first end portion 1211, and the first extension portion 122 may be extended along the radial direction of the installation body 121. The first extension portion 122 may be arranged parallel to the radial direction of the installation body 121, or the first extension portion 122 may have a preset angle with the radial direction of the installation body 121. The first extension portion 122 may be extended along the circumference of the installation body 121, or the first extension portion 122 may be a protruding structure distributed along the circumference of the installation body 121.

[0065] The first extension portion 122 is connected to a second extension portion 123 on one side away from the installation body 121. The second extension portion 123 can be arranged parallel to the axial direction of the first installation hole 11a. The second extension portion 123 can be arranged to extend along the circumference of the installation body 121, or the second extension portion 123 is a protrusion structure distributed along the circumference of the installation body 121.

[0066] The first extension part 122, the second extension part 123 and the part of the mounting body 121 form a mounting groove 122a, and the mounting groove 122a is used to cooperate with the light-transmitting lens 16. The light-transmitting lens 16 includes: a lens body 161, and the lens body 161 is used to cover the opening at the front end of the second mounting hole. In this way, the lens body 161, the partition 1213 and the first end 1211 can form a relatively closed receiving space, and the heart rate sensor 13 is arranged in the space, which can play a role of sealing protection.

[0067] For example, the size of the lens body 161 can be slightly smaller than the opening of the first mounting hole 11a at the front end, so that the light-transmitting lens 16 can slide smoothly along the axial direction of the first mounting hole 11a together with the mounting bracket 12, and can also play a shielding and protective role to reduce the accumulation of dust and other dirt at the opening of the first mounting hole 11a. The shape of the lens body 161 can be compatible with the shape of the opening of the first mounting hole 11a at the front end; for example, the opening of the first mounting hole 11a at the front end is oblong, and the lens body 161 is also oblong.

[0068] The edge of the lens body 161 is provided with a folded edge 162 folded backwards, and the folded edge 162 is inserted into the mounting groove 122a. The folded edge 162 can be fixedly arranged in the middle of the mounting groove 122a by means of interference fit, bonding, or clamping.

[0069] In some examples, the folded edge 162 faces the surface of the hole wall of the first mounting hole 11a and is located in a region away from the lens body 161, and is recessed in a direction away from the hole wall of the first mounting hole 11a to form a docking surface that docks with the second extension portion 123 of the mounting bracket 12.
