Abstract
Description
Technical Field
[0001] This invention relates to the field of head-mounted display technology, and more particularly to a head pad assembly, head-mounted support, and head-mounted display device for a head-mounted device. Background Technology
[0002] Head-mounted displays (HMDs) magnify images on ultra-micro displays through an optical system, projecting the images onto the retina and presenting them as large-screen images to the viewer. They can achieve different effects such as virtual reality (VR), augmented reality (AR), and mixed reality (MR).
[0003] In head-mounted display devices, the main unit is typically worn on the user's head using a headband or strap. Given that different users have different head circumferences, the length of the strap needs to be adjusted to ensure a comfortable fit. Currently, head-mounted display devices require manual adjustment of the tightness, which is inconvenient. Summary of the Invention

[0005] To achieve the above objectives, embodiments of the present invention provide a head pad assembly for a head-mounted device, the head pad assembly comprising:
[0006] Head pad mounting components;
[0007] A flexible head pad is disposed on the side of the head pad mounting member facing the wearer's head; and

[0011] A force transmission plate is disposed on the side of the force receiving plate away from the wearer's head, and the force transmission plate is connected to the head pad mounting component;
[0012] An elastic element connects the force-receiving plate and the force-transmitting plate; and
[0013] A stress-reducing element is disposed on the end face of the force transmission plate opposite to the elastic element.
[0014] Optionally, in one embodiment of the present invention, the end face of the force-receiving plate facing the force-transmitting plate is provided with a first protruding rib, and a plurality of the first protruding ribs are provided at intervals along the circumference of the elastic member to form a first covering space, and one end of the elastic member is disposed in the first covering space.
[0015] And / or, the end face of the force transmission plate facing the force receiving plate is provided with a second protruding rib, and multiple second protruding ribs are provided at intervals along the circumference of the elastic member to form a second covering space, and the other end of the elastic member is located in the second covering space.
[0016] Optionally, in one embodiment of the present invention, the end face of the flexible brain pad facing the brain pad mounting member is provided with a first blind hole, and the end face of the brain pad mounting member facing the flexible brain pad is provided with a second blind hole. The first blind hole and the second blind hole cooperate to form a mounting hole, and the pressure acquisition structure is disposed in the mounting hole; wherein, the force-bearing plate is disposed in the first blind hole, and the stress member and the force-transmitting plate are disposed in the second blind hole.
[0017] Optionally, in one embodiment of the present invention, the stress element is any one of a stress gauge, a strain gauge, or a stress meter.
[0018] Optionally, in one embodiment of the present invention, the pressure acquisition structure is arranged in an array of multiple units.
[0019] To achieve the above objectives, embodiments of the present invention provide a head-mounted support, the head-mounted support comprising:
[0020] Straps;
[0021] A tension adjustment component, which is connected to the strap drive to drive the strap to move;
[0022] A head pad assembly, disposed on the side of the elasticity adjustment assembly facing the wearer's head, wherein the head pad assembly is the head pad assembly of the head-mounted device described above; and
[0023] The controller is electrically connected to both the pressure acquisition structure and the tension adjustment component. The controller controls the tension adjustment component to adjust the tightness of the strap based on the pressure value acquired by the pressure acquisition structure at a preset position.
[0024] Optionally, in one embodiment of the present invention, the headband further includes a back shell, the tension adjustment component is disposed on the side of the back shell away from the wearer's head, and the head pad component is disposed on the side of the back shell facing the wearer's head.

[0027] Compared to existing technologies, the technical solution proposed in this invention utilizes a pressure acquisition structure to collect the force on the flexible head pad, specifically the pressure of the straps on the wearer's head. This force is transmitted to the controller for analysis and processing, allowing the tension adjustment component to automatically adjust the strap tightness to meet the needs of different wearers or usage scenarios. This replaces manual strap adjustment, improving the convenience of adjustment. Furthermore, one end of the pressure acquisition structure is embedded within the flexible head pad, enabling the acquisition of force in three different directions: X, Y, and Z. Essentially, the pressure acquisition structure collects the resultant force of the flexible head pad under different directions, preventing insufficient detection of force and improving the accuracy and sensitivity of the force acquisition. This, in turn, enhances the controller's accuracy in controlling the tension adjustment component, meeting the needs of different head circumferences and improving wearer comfort. In addition, the other end of the pressure acquisition structure is connected to the brain pad mounting component. Because the brain pad mounting component is made of a relatively hard material, the end of the pressure acquisition structure away from the flexible brain pad is fixed to the brain pad mounting component. This prevents the entire pressure acquisition structure from deforming synchronously with the flexible brain pad and affecting the accuracy of the detected force, thereby further improving the accuracy and sensitivity of the force detection results of the pressure acquisition structure.

[0040] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope required by the embodiments of the present invention.
[0041] In head-mounted display devices, the main unit is typically worn on the user's head using a headband or strap. Currently, existing head-mounted displays cannot automatically adapt to the user's head circumference, requiring manual adjustment of the strap length. Sometimes, multiple adjustments may be needed to find the optimal fit, which is time-consuming and laborious. Furthermore, the existing adjustment mechanisms in head-mounted displays are prone to shifting due to gravity or movement, which negatively impacts the stability of the device and affects visual display quality. Continuous manual correction is also necessary to ensure stable wear. Moreover, the strap tightness needs to be manually readjusted when switching between different usage scenarios. Generally, the strap needs to be tightened for gaming and sports to prevent it from slipping, while it needs to be loosened for watching movies and relaxing to reduce pressure on the head.
[0042] To meet the aforementioned usage requirements, wearable products with intelligent and electric adaptive adjustment of the straps have gradually become a research and development hotspot. Adaptive adjustment requires high-precision and highly sensitive head force feedback. Current head force feedback typically involves directly attaching stress pads to the surface of a flexible head pad or the back shell behind it. Because the flexible material absorbs deformation caused by head pressure, this results in low sensitivity and accuracy of stress detection, negatively impacting the convenience and precision of the adaptive adjustment of the straps.
[0043] In view of this, embodiments of the present invention propose a head pad assembly, a head frame, and a head-mounted display device. The pressure acquisition structure can collect the force on the flexible head pad. After the force on the flexible head pad is transmitted to the controller for analysis and processing, the tension adjustment component can be controlled to automatically adjust the tightness of the straps to meet the wearing needs of different wearers or different usage scenarios. This replaces the manual adjustment of the straps and improves the convenience of adjusting the tightness of the straps.
[0044] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.
[0045] like Figures 1-4 As shown in the figure, an embodiment of the present invention provides a head pad assembly 100 for a head-mounted device, the head pad assembly 100 comprising:
[0046] Head pad mounting component 110;
[0047] A flexible head pad 120 is disposed on the side of the head pad mounting member 110 facing the wearer's head; and
[0048] The pressure acquisition structure 130 has one end embedded inside the flexible brain pad 120, and the other end connected to the brain pad mounting component 110.
[0049] In this embodiment, the pressure acquisition structure 130 collects the force on the flexible head pad 120, i.e., the pressure of the strap on the wearer's head. This force is transmitted to the controller for analysis and processing, allowing the tension adjustment component to automatically adjust the strap tightness to meet the needs of different wearers or usage scenarios. This replaces manual strap adjustment and improves the convenience of adjusting strap tightness. Furthermore, one end of the pressure acquisition structure 130 is embedded inside the flexible head pad 120, allowing it to collect the force on the flexible head pad 120 in three different directions: X, Y, and Z. Essentially, the pressure acquisition structure 130 collects the resultant force of the flexible head pad 120 under different directions, preventing the force from being too small to be detected. This improves the accuracy and sensitivity of the force acquisition on the flexible head pad 120, thereby enhancing the controller's accuracy in controlling the tension adjustment component, meeting the needs of different wearers' head circumferences, and improving the wearer's comfort during device use. In addition, the other end of the pressure acquisition structure 130 is connected to the brain pad mounting component 110. Because the material of the brain pad mounting component 110 is relatively hard, the end of the pressure acquisition structure 130 away from the flexible brain pad 120 is fixed on the brain pad mounting component 110. This can prevent the entire pressure acquisition structure 130 from deforming synchronously with the flexible brain pad 120 and affecting the accuracy of the detected force, thereby further improving the accuracy and sensitivity of the force detection results of the pressure acquisition structure 130.
[0050] Specifically, the head pad assembly 100 of the head-mounted device includes a head pad mounting component 110, a flexible head pad 120, and a pressure acquisition structure 130. The head pad mounting component 110 is made of a rigid material, such as plastic, and provides a mounting position and support for the flexible head pad 120. The flexible head pad 120 is mounted on the head pad mounting component 110 and, supported by the head pad mounting component 110, fits against the back of the wearer's head. It can be understood that the flexible head pad 120 is a contoured structure adapted to the back of the human head. The flexible head pad 120 is made of a flexible material, such as plastic, foam, or silicone, which can improve the wearer's comfort when the flexible head pad 120 contacts the back of the wearer's head. As an optional method, the flexible head pad 120 and the head pad mounting component 110 can be tightly bonded together using ultrasound or adhesive structures to ensure a strong connection between the flexible head pad 120 and the head pad mounting component 110. The pressure sensing structure 130 is used to detect the pressure on the wearer's head. Since the flexible head pad 120 is in direct contact with the wearer's head, the force on the flexible head pad 120 during wear is equivalent to the pressure on the wearer's head. Therefore, by detecting the force on the flexible head pad 120 during wear, the tightness of the strap can be determined, and the tension adjustment component can be controlled to adjust the tightness of the strap. In this embodiment, one end of the pressure sensing structure 130 is embedded inside the flexible head pad 120, and the other end is connected to the head pad mounting component 110. This allows for the collection or detection of the total force on the flexible head pad 120 in different directions during wear, thereby improving the accuracy of the strap tightness determination.
[0051] For example, refer to Figure 1 , Figure 3 as well as Figure 4 In one embodiment of the present invention, the pressure acquisition structure 130 includes:
[0052] The load-bearing plate 131 is embedded inside the flexible head pad 120;
[0053] Force transmission plate 132 is located on the side of force plate 131 away from the wearer's head, and force transmission plate 132 is connected to head pad mounting component 110.
[0054] Elastic element 133 connects force-bearing plate 131 and force-transmitting plate 132; and
[0055] Stress member 134 is provided on the end face of force transmission plate 132 away from elastic member 133.
[0056] During the wearing of the head-mounted device, the back of the wearer's head will first come into contact with the flexible head pad 120. Due to its flexible and easily deformable nature, the flexible head pad 120 will deform. However, because the size of the wearer's head varies, the direction of force on the flexible head pad 120 is irregular. Generally, the flexible head pad 120 is subjected to forces in three different directions: X, Y, and Z. This results in the deformation of the flexible head pad 120 being unpredictable. Furthermore, if the flexible head pad 120 deforms too much after contact with the back of the head, it may exceed the deformation range of the strain structure itself, easily leading to the failure of the strain structure's stress detection. Additionally, if the strain structure is directly attached to the back shell 200 for testing, the force is transmitted to the back shell 200 after the deformation of the flexible head pad 120. Because the deformation of the flexible head pad 120 itself attracts a large amount of strain, the stress detection structure will generally have no strain or very little strain, also easily leading to the failure of the strain structure's stress detection.
[0057] Therefore, the pressure acquisition structure 130 in this embodiment includes a force-bearing plate 131, a force-transmitting plate 132, an elastic element 133 connecting the force-bearing plate 131 and connected in series, and a stress element 134 disposed on the force-transmitting plate 132. The force-bearing plate 131 is embedded inside the flexible head pad 120 and is in direct contact with the flexible head pad 120. The forces on the flexible head pad 120 in three different directions (X, Y, and Z) are applied to the force-bearing plate 131. That is, the pressure on the force-bearing plate 131 is the resultant force of the forces on the flexible head pad 120 in different directions, thereby directly converting the forces on the flexible head pad 120 in the three different directions into strains on the force-bearing plate 131 in the three directions. The force transmission plate 132 is connected to the head pad mounting component 110. The force transmission plate 132 and the force receiving plate 131 are connected by an elastic element 133, allowing the strain of the force receiving plate 131 in three directions to be converted into the strain of the elastic element 133 in three directions. Furthermore, the strain of the elastic element 133 in three directions is converted into the strain of the force transmission plate 132 in three directions. The stress element 134 is mounted on the force transmission plate 132, meaning it is in direct contact with the force transmission plate 132. This allows the strain of the force transmission plate 132 in three directions to be converted into the strain of the stress element 134 in three directions. When the stress element 134 changes due to strain, its resistance changes. This change in resistance is converted into a change in voltage, and a voltage signal is output. The amplifier circuit receives this voltage signal, amplifies it, and outputs it to the detection system. The system then calculates the pressure curve value corresponding to the voltage output based on the elastic modulus of the material, i.e., E = σ / ε, where E is the elastic modulus, σ is the stress, and ε is the strain. Through the above scheme, the pressure exerted on the flexible head pad 120 by different head circumference sizes can be directly and accurately fed back to the stress detection system, thereby providing relevant input data for the adaptive adjustment of the straps. It can be understood that by accurately detecting the tightness of the straps after the user wears the device through the pressure acquisition structure 130, real-time feedback of head circumference pressure data is achieved. When the straps become loose or need to be tightened during gaming or sports activities, the system uses an adaptive adjustment algorithm to achieve real-time intelligent adjustment of the straps. It should be noted that this embodiment mainly aims to improve the accuracy of the pressure detection results, i.e., to obtain relatively accurate real-time feedback of head circumference pressure data. The specific adjustment algorithm can adopt commonly used algorithms and is not limited here. As an optional feature, the stress element 134 can be any one of a stress sheet, strain gauge, or stress meter, and the elastic element 133 can be a spring, which is also not limited here.
[0058] For example, refer to Figure 2 In one embodiment of the present invention, multiple pressure sensing structures 130 are arranged in an array. Specifically, the multiple pressure sensing structures 130 are positioned corresponding to the back of the wearer's head, increasing the contact pressure detection points between the back of the head and the flexible head pad 120, thereby improving the sensitivity and accuracy of stress detection.
[0059] For example, in one embodiment of the present invention, the end face of the force plate 131 facing the force transmission plate 132 is provided with a first protruding rib, and a plurality of the first protruding ribs are arranged at intervals along the circumference of the elastic member 133 to form a first covering space, and one end of the elastic member 133 is located in the first covering space.
[0060] And / or, the end face of the force transmission plate 132 facing the force receiving plate 131 is provided with a second protruding rib, and multiple second protruding ribs are arranged at intervals along the circumference of the elastic member 133 to form a second covering space, and the other end of the elastic member 133 is located in the second covering space.
[0061] Specifically, to facilitate the installation of the elastic element 133, a first protruding rib is provided on the force-bearing plate 131, and / or a second protruding rib is provided on the force-transmitting plate 132.
[0062] The first rib is provided on the end face of the force-bearing plate 131 facing the force-transmitting plate 132. One end of the first rib is connected to the force-bearing plate 131, and the other end of the first rib extends toward the force-transmitting plate 132. At least two first ribs are provided at intervals along the periphery of the elastic member 133, such as two, three, or four. Multiple first ribs form a first covering space. The end of the elastic member 133 near the force-bearing plate 131 extends into the first covering space and abuts against the force-bearing plate 131. That is, the first covering space is fitted outside the end of the elastic member 133 near the force-bearing plate 131, thus achieving the limitation of the end of the elastic member 133.
[0063] The second rib is provided on the end face of the force transmission plate 132 facing the force receiving plate 131. One end of the second rib is connected to the force transmission plate 132, and the other end of the second rib extends toward the force receiving plate 131. At least two second ribs are provided at intervals along the periphery of the elastic member 133, such as two, three, or four. Multiple second ribs form a second covering space. The elastic member extends the end near the force transmission plate 132 into the second covering space and abuts against the force transmission plate 132. That is, the second covering space is fitted outside the end of the elastic member 133 near the force transmission plate 132, thus limiting the other end of the elastic member 133.
[0064] It is understandable that by cooperating with the first and second ribs, the elastic element 133 can be connected to the force plate 131 and the force transmission plate 132 without the need for other fixing structures, which simplifies the installation process of the elastic element and improves the assembly efficiency.
[0065] For example, in one embodiment of the present invention, the end face of the flexible head pad 120 facing the head pad mounting member 110 is provided with a first blind hole, and the end face of the head pad mounting member 110 facing the flexible head pad 120 is provided with a second blind hole. The first blind hole and the second blind hole cooperate to form a mounting hole, and the pressure acquisition structure 130 is disposed in the mounting hole; wherein, the force-bearing plate 131 is disposed in the first blind hole, and the stress member 134 and the force transmission plate 132 are disposed in the second blind hole. Specifically, after the flexible head pad 120 is assembled on the head pad mounting member 110, the first blind hole and the second blind hole correspond to each other and together form a mounting hole, and the pressure acquisition structure 130 is disposed in the mounting hole. As an optional method, the force-bearing plate 131 can be fixed in the first blind hole by adhesive bonding, and the force transmission member can also be fixed in the second blind hole by adhesive bonding.

[0067] Straps;

[0069] A head cushion assembly 100 is located on the side of the tension adjustment assembly facing the wearer's head. The head cushion assembly 100 is the head cushion assembly 100 of the head-mounted device described above.
[0070] The controller, pressure acquisition structure 130, and tension adjustment component are all electrically connected to the controller. The controller controls the tension adjustment component to adjust the tightness of the strap based on the pressure value acquired by the pressure acquisition structure 130 at a preset position.
[0071] Specifically, the specific structure of the headrest assembly 100 is as described in the above embodiments. Since the headband adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here. As an optional method, the tension adjustment assembly can be a gear and rack mechanism, or other adjustment methods can be used, which are not limited here.
[0072] For example, refer to Figure 3 and Figure 4 In one embodiment of the present invention, the headband further includes a back shell 200, a tension adjustment component is disposed on the side of the back shell 200 away from the wearer's head, and a head pad assembly 100 is disposed on the side of the back shell 200 facing the wearer's head. Thus, the tension adjustment component can be easily installed using the back shell 200.
[0073] For example, in one embodiment of the present invention, the head pad mounting component 110 is detachably connected to the rear shell 200. Specifically, the head pad mounting component 110 can be connected to the rear shell 200 by means of a snap-fit or magnetic structure, which can improve the convenience of assembling and disassembling the head pad mounting component 110 and the rear shell 200.
