Description
Technical Field
The invention relates to the field of head display supports, in particular to a head display supporting device.
Background
VR simulation operating skill training is an emerging application direction for virtual display technology in recent years. Compared with the traditional VR teaching product, the simulation operation skill training is more focused on the learning and training of the hand action skills of the user. The outstanding characteristics of the product are that operators can realize real operation feeling in the virtual environment through the virtual touch technology, so that the operation skill is better mastered. For example, in clinical medical operation teaching, various operations such as cutting, puncturing, sewing and the like are required to have high accuracy and fineness, and these operation skills can only be accumulated by doctors in real operations in the past, and for new doctors, the scarcity of clinical opportunities is a main reason for the long culture period of the medical staff nowadays. By utilizing the latest virtual reality technology, the modern simulated operation teaching product can enable operators to truly experience the operation process, and greatly quicken the cultivation process of doctors.
In simulated operating skill training products, operators often need to hold simulated instrument effectors (e.g., scalpel effectors, syringe effectors, etc.) that provide the same gripping feel and manner of operation to the operator as with a real instrument. The effector is also connected to a force feedback mechanical arm that is responsible for outputting the operative force sensation to the user. In this way, such products may allow a user to experience a sense of real operation in a fully immersive virtual environment.
However, during the skill training process, the user often needs to replace various operating devices, and the user needs to leave the virtual environment and return to the real environment for operation when replacing the devices. However, in order to ensure the immersive effect of VR, the existing VR head display device is usually directly worn and fixed on the head of the user, and because there is an objective requirement for switching between the virtual environment and the real environment in the process of training the operation skills, the product used as a teaching is likely to need multiple persons to use alternatively, and the existence of these limitation conditions results in that the head mounted display used in the mainstream of the current VR product is not suitable for the simulation operation skill training system. The problem of switching virtual and real environments can be solved by adopting a mode of fixing the head display, but the flexibility of the head-mounted display is lost by the fixed head display, when the head-mounted display is used in a head-mounted mode, a user can rotate the head at will to watch scenes in any direction, and the flexibility is lost by adopting the fixed mode.

Referring to fig. 1 to 3, a head support device according to a first embodiment of the present invention includes a glasses frame 10 for fixing VR glasses 40, a horizontal rotating shaft assembly 20 for rotating the glasses frame 10 up and down, and a vertical rotating shaft assembly 30 for horizontally rotating the glasses frame 10, wherein:
the horizontal rotating shaft assembly 20 comprises an upper rotating support 21, a lower rotating support 21, a torsion spring cover 22, an optical axis 23 and a torsion spring 24, wherein the upper rotating support 21 and the lower rotating support 21 are arranged on two sides of the glasses support 10, the torsion spring cover 22 is respectively fixed on the upper rotating support 21, the lower rotating support 21 and the vertical rotating shaft assembly 30, the optical axis 23 is rotationally connected with the torsion spring cover 22, the torsion spring 24 is sleeved on the optical axis 23, one end of the upper rotating support 21 and one end of the lower rotating support 21 are fixedly connected with the glasses support 10, and the other end of the upper rotating support 21 is rotationally connected with the vertical rotating shaft assembly 30 through the optical axis 23.
It can be understood that the VR glasses 40 are suspended and fixed at a specific position through the glasses support 10, the horizontal rotating shaft assembly 20 connected with the glasses support 10 and the vertical rotating shaft assembly 30 connected with the horizontal rotating shaft assembly 20 realize the function of up-down and horizontal two-degree-of-freedom rotation of the VR glasses 40 along with the glasses support 10, specifically, the horizontal rotating shaft assembly 20 comprises an up-down rotating support 21, a torsion spring cover 22, an optical axis 23 and a torsion spring 24, the torsion spring cover 22 is respectively arranged on the vertical rotating shaft assembly 30 and the up-down rotating support 21 positioned at two sides of the glasses support 10, the torsion spring cover 22 is provided with a shaft hole for accommodating the optical axis 23, the outer side of the optical axis 23 is sleeved with a torsion spring 24 with two ends connected with the torsion spring cover 22, the rotation connection between the horizontal rotating shaft assembly 20 and the vertical rotating shaft assembly 30 is realized through the optical axis 23, the up-down rotation function of the head display support device is realized, and the left-right rotation function of the head display support device is realized through the vertical rotating shaft assembly 30, so that the head display support device is used as the existing head display VR device after being installed, and the head display device is flexible, and the support 10 can be moved out of a virtual environment between a wearer and the glasses support 10 and a wearer at any time. Therefore, the invention solves the problem that the VR head display device in the prior art cannot meet the requirement that the visual field is flexible and the virtual and real scenes are switched rapidly when the user performs operation skill training.
It should be noted that, the cooperation of the torsion spring 24 and the torsion spring cover 22 is used for counteracting the gravity of the glasses bracket 10 and the VR glasses 40, so that when the VR glasses 40 are fixed on the glasses bracket 10, they can be suspended at a specific position, and thus the user does not need to bear the gravity of the VR glasses 40 and the glasses bracket 10, and the use is more convenient; and thus, when the user switches between the virtual environment and the real environment, the VR glasses 40 are not shifted due to the lack of head support of the user, and further, the VR viewing angle shift needs to be readjusted by the user.
In addition, in specific use, an important function of the skill teaching system is to achieve teaching purposes, and the comfort of use is not as high as that of entertainment products. The design of the virtual scene only needs to enable the user to see the operation area, and the head does not need to be rotated in all directions. Therefore, the head support device needs to provide two necessary rotational degrees of freedom of pitching up and down and rotating the head left and right within a certain angle range, and other degrees of freedom are not necessary. And, can complement the requirement of more degrees of freedom through other interaction modes (such as a handle, a key mouse, a pedal and the like).
Specifically, the vertical shaft assembly 30 includes a left and right rotating bracket 31 rotatably connected to the horizontal shaft assembly 20, a rotating sleeve 32 fixedly connected to the top of the left and right rotating bracket 31, and a fixing sleeve 33 sleeved outside the rotating sleeve 32, wherein a flange 321 extends outwards from a side of the rotating sleeve 32 away from the left and right rotating bracket 31, the outer diameter of the flange 321 is larger than the inner diameter of the fixing sleeve 33, and a side of the fixing sleeve 33 away from the left and right rotating bracket 31 is used for connecting a fixture. Through the rotation connection between the rotating sleeve 32 and the fixed sleeve 33 at the top of the left and right rotating brackets 31, the left and right rotating brackets 31 rotate relative to the fixed sleeve 33 to carry out horizontal rotation with the horizontal rotating shaft assembly 20 and the glasses bracket 10 fixed with the VR glasses 40. The head support device is suspended at a specific position due to the connection of one side of the fixing sleeve 33 with the fixture. In addition, a flange 321 with an outer diameter larger than the inner diameter of the fixed sleeve 33 is arranged on one side of the rotating sleeve 32, so as to ensure that the fixed sleeve 33 is clamped between the rotating sleeve 32 and the left and right rotating brackets 31. It should be noted that, the rotation axis of the horizontal rotation axis assembly 20 is located approximately at the left and right rotation center axis of the human head according to the ergonomic principle, and the arrangement thereof can effectively reduce the friction resistance moment.
In addition, one end of the up-down rotating bracket 21 is fixedly connected with the glasses bracket 10 through the bolt 26, the distance between the axis of the optical axis 23 and the axis of the bolt 26 in the height direction is 50-80 mm, and the distance between the axis of the optical axis 23 and the axis of the bolt 26 in the front-rear direction is 110-150 mm, so that the optical axis 23 is positioned at any cervical vertebra joint of a user when the device is used by the user. The head display supporting device is provided with the optical axis 23, so that the head display is arranged on the supporting device, and when a user uses the head display, the user can wear the head display to perform the actions of nodding and lifting the head. And, according to ergonomic analysis, the optical axis 23 is disposed at a height direction distance of 50 to 80 mm and a front-rear direction distance of 110 to 150 mm of the bolt 26 so that the rotation axis of the head moves downward along the cervical vertebrae when the human body performs the nodding motion. So that the user can keep the natural movement mode of the human body in the whole process of rotating the head up and down, and meanwhile, the head display can keep fit with the face of the user. Specifically, the optical axis 23 is located at the first cervical vertebra. Then, as the head is depressed, the optical axis 23 gradually moves downward relative to the human body, and when the limit (about 75 °) is approached, the optical axis 23 moves downward to the seventh cervical vertebra. The range of the relative rotation angle of each cervical vertebra joint is gradually reduced from top to bottom. About 30 °,15 °,10 °,8 °,6 °,4 °,2 ° in this order from the first to the seventh.
By way of example and not limitation, in some alternative embodiments, the horizontal hinge assembly 20 further includes a jaw rest 25, with both sides of the jaw rest 25 being connected to the upper and lower swivel brackets 21, respectively, such that the jaw rest 25 is positioned below the eyeglass frame 10. The jaw support 25 is provided for a user to perform a simulation operation skill teaching, so that the placement of the chin on the jaw support 25 is more labor-saving. In addition, when setting up jaw support 25 and making the user turn round about, can drive VR glasses 40 to rotate with the help of the lower jaw force, and not only support with glasses frame 10 and support and bear against and exert force and drive VR glasses 40 to rotate, and then make the user use more convenient laborsaving.
Further, the glasses frame 10 is provided with a cheekbone pad 11 at a side close to the vertical rotation shaft assembly 30. The cheekbone pad 11 is used for abutting the eyebox when the user uses, so that the user can feel more comfortable when abutting without being painful by the glasses bracket 10, in addition, the friction force between the cheekbone pad 11 and the eyebox of the user is larger relative to the smooth glasses bracket 10, and further, the user can apply force to the glasses bracket 10 more easily by means of the cheekbone pad 11, so that the glasses bracket 10 is driven to rotate up and down or left and right.
In addition, a fixing seat 331 is disposed on a side of the fixing sleeve 33 away from the left and right rotating brackets 31, and the fixing seat 331 is used for connecting a fixed object. The fixing seat 331 is used for being connected and fixed with a fixed object, so that the fixing sleeve 33 is suspended and fixed at a specific position, and the head display supporting device realizes that the head display rotating shaft is suspended at a specific position and can horizontally rotate around the axis of the fixing sleeve 33 through the cooperation of the rotating sleeve 32 and the fixing sleeve 33.
Further, a bearing 36 is sleeved outside the rotating sleeve 32, and the bearing 36 is positioned between the rotating sleeve 32 and the fixed sleeve 33. The bearing 36 is provided to reduce friction generated by the mutual rotation between the rotating sleeve 32 and the fixed sleeve 33, so that the user can drive the glasses bracket 10 to drive the VR glasses 40 to horizontally rotate more easily. Specifically, the bearing 36 employs a rolling bearing to further reduce rotational friction of the head during left-right rotation.
Further, a washer 37 is further provided on the outer side of the rotary sleeve 32, and the washer 37 is located between the left and right rotary brackets 31 and the fixed sleeve 33. The washer 37 is arranged between the fixed sleeve 33 and the left and right rotating brackets 31, so that the rotating sleeve 32 rotates more stably relative to the fixed sleeve 33, and the condition of up and down movement can not occur.
Referring to fig. 4, a head support device according to a second embodiment of the present invention is shown, and the second embodiment has the same general structure as the first embodiment, and the only difference is that the vertical shaft assembly 30 includes a left and right rotating support 31 rotatably connected to the horizontal shaft assembly 20, a sliding block 34 fixed on the top of the left and right rotating support 31, and a circular arc sliding rail 35 adapted to the sliding block 34, wherein a side of the circular arc sliding rail 35 away from the sliding block 34 is used for connecting a fixture. In this embodiment, the circular arc slide rail 35 and the slide block 34 are matched to enable the head display supporting device to horizontally rotate. The cooperation of slider 34 and circular arc slide rail 35 is relative to the cooperation of swivel mount 32 and fixed cover 33, and although the angle of horizontal rotation is less by circular arc slide rail 35's restriction, rotates more laborsaving, and the required pivoted angle of head is limited when the user carries out the teaching of simulation operation skill, therefore the cooperation of slider 34 and circular arc slide rail 35 is more convenient when in actual use.
In summary, in the head display supporting device according to the above embodiment of the present invention, the VR glasses 40 are suspended and fixed at a specific position by the glasses support 10, then the horizontal rotating shaft assembly 20 connected with the glasses support 10 and the vertical rotating shaft assembly 30 connected with the horizontal rotating shaft assembly 20 realize the function of rotating the VR glasses 40 along with the up-down and horizontal two degrees of freedom of the glasses support 10, specifically, the horizontal rotating shaft assembly 20 includes the up-down rotating support 21, the torsion spring cover 22, the optical axis 23 and the torsion spring 24, the torsion spring cover 22 is respectively disposed on the vertical rotating shaft assembly 30 and the up-down rotating support 21 disposed at two sides of the glasses support 10, the axle hole is disposed on the torsion spring cover 22 for accommodating the optical axis 23, the torsion spring 24 with two ends connected with the torsion spring cover 22 is sleeved outside the optical axis 23, the rotating connection between the horizontal rotating shaft assembly 20 and the vertical rotating shaft assembly 30 is realized by the optical axis 23, and then the up-down rotating function of the head display supporting device is realized by the vertical rotating shaft assembly 30, so that the head display supporting device is mounted with the VR glasses 40, and then the head display supporting device can be flexibly moved out of the head display support 10 and the head display device is flexibly used by the user and the user. Therefore, the invention solves the problem that the VR head display device in the prior art cannot meet the requirement that the visual field is flexible and the virtual and real scenes are switched rapidly when the user performs operation skill training.
