[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Embodiment 1

[0045] To prevent excessive pressure of the VR glasses on the head, as Figures 1 to 6 shown, the present invention proposes a VR glasses, including a device main body 1, side connectors 2, a positioning member 3 and a top connection assembly 4. A top connection assembly 4 is provided between the device main body 1 and the positioning member 3, and the top connection assembly 4 can adjust its own length.

[0046] Two side connectors 2 are connected to the side of the device main body 1, and the other ends of the two side connectors 2 are provided with the same positioning member 3. The positioning member 3 can adjust the use length of the side connectors 2. A top connection assembly 4 is provided between the device main body 1 and the positioning member 3, and the top connection assembly 4 can adjust its own length. A supplementary pressure assembly 5 is also provided on the positioning member 3.

[0047] It should be noted that a facial contact sleeve for increasing comfort is provided at the position of the device main body 1 close to the head. A cotton fabric for absorbing facial sweat is arranged inside the facial contact sleeve. An adjusting mechanism for adjusting the distance between the two eyes is arranged inside the device main body 1. Both of the two side connectors 2 are connected to the device main body 1 at one end and the positioning member 3 at the other end.

[0048] In this embodiment, a telescopic part 31 is arranged inside the positioning member 3. The telescopic part 31 is connected to one end of the side connector 2 close to the positioning member 3, and the telescopic part 31 can adjust the use length of the side connector 2. A lower support block 32 is arranged on the side of the positioning member 3 away from the top connection assembly 4.

[0049] It should be noted that the side connector 2 is made of a rigid material and has a certain toughness. The telescopic part 31 is located inside the positioning member 3. The setting of the lower support block 32 can increase the contact area between the positioning member 3 and the human head, thereby reducing the pressure on the head. And the arc structure of the lower support block 32 can prevent the VR glasses from falling off; the telescopic part 31 includes a rack and a gear. The rack is connected to one end of the side connector 2 close to the positioning member 3. The racks on the two side connectors 2 are both engaged with the gear. A driving member is arranged on the gear shaft. The driving member makes the gear rotate, and the gear drives the rack to move, thereby adjusting the length of the side connector 2 extending out of the positioning member 3 and changing the working length of the side connector 2.

[0050] In this embodiment, the top connection assembly 4 includes a fixing member 41. The fixing member 41 is connected to the positioning member 3. A sliding groove 411 is opened on the side of the fixing member 41 away from the device main body 1. An adjusting member 43 is arranged in the sliding groove 411. The adjusting member 43 can slide in the sliding groove 411. A connecting belt 42 is arranged between the adjusting member 43 and the device main body 1, and the connecting belt 42 is located in the sliding groove 411. A flexible layer is arranged on the side of the top connection assembly 4 close to the human head.

[0051] It should be noted that the fixing member 41 has a certain flexibility and can closely adhere to the human head when adjusting the length of the top connection assembly 4. One end of the fixing member 41 is fixed to the positioning member 41, and the other end extends towards the device body 1 without contacting the device body 1. On the side of the fixing member 41 away from the human head is a sliding groove 411. The adjusting member 43 slides in the sliding groove 411, and the connecting belt 42 is also located in the sliding groove 411. The connecting belt 42 extends from one end of the fixing member 41 away from the positioning member 3. After the connecting belt 42 extends, it connects to the device body 1. By sliding the adjusting member 43, the length of the connecting belt 42 extending from the fixing member 41 can be changed, thereby changing the length of the top connection assembly 4.

[0052] A winding part 431 is provided on the adjusting member 43. One end of the connecting belt 42 is wound in the winding part 431, and the other end is connected to the device body 1. A clamping mechanism 432 is provided inside the adjusting member 43.

[0053] It should be noted that one end of the connecting belt 42 located at the adjusting member 43 is wound on the winding wheel in the winding part 431. A rotary driving member is provided on the shaft of the winding wheel, which can drive the winding wheel to rotate, wind or relax the connecting belt 42, thereby adjusting the length of the top connection assembly 4; the sliding of the adjusting member 43 roughly adjusts the length of the top connection assembly 4, and the winding part 431 finely adjusts the length. The two cooperate to ensure that the pressure of the top connection assembly 4 on the human head will not be too large and prevent damage to the human head.

[0054] The clamping mechanism 432 includes a receiving groove 4322. A clamping block 4321 is provided in the receiving groove 4322. The clamping block 4321 slides in the receiving groove 4322. A clamping slot 4111 cooperating with the clamping block 4321 is provided in the sliding groove 411. A first elastic member 4323 is provided on the side of the clamping block 4321 away from the clamping slot 4111, and the other end of the first elastic member 4323 is connected to the inner side of the receiving groove 4322. A pull rope 4324 is also provided on the side of the clamping block 4321 away from the clamping slot 4111. A pushing member 4325 for pushing its movement is provided in the middle of the pull rope 4324. The pushing member 4325 is slidably connected to the adjusting member 43. A second elastic member 4326 is provided outside the pushing member 4325. One end of the second elastic member 4326 is connected to the pushing member 4325, and the other end is connected to the adjusting member 43.

[0055] It should be noted that the clamping mechanism 432 is located inside the adjusting member 43 and also in the sliding groove 411. When the length of the top connection assembly 4 decreases, that is, when the connecting belt 42 is tightened, when the adjusting member 43 moves towards the positioning member 3, the clamping block 4321 will be pushed into the receiving groove 4322 by the clamping slot 4111, enabling the connecting belt 42 to be smoothly tightened; when the connecting belt 42 needs to be relaxed, the clamping slot 4111 will catch the clamping block 4321. At this time, moving the pushing member 4325 drives the pull rope 4324 to disengage the clamping block 4321 from the clamping slot 4111, allowing the adjusting member 43 to move smoothly.

[0056] In this embodiment, through the setting of the top connection component 4, the pressure of the VR glasses on the human head is finely adjusted, so that the user will not feel discomfort due to pressure problems, which increases the comfort when using the VR glasses. At the same time, it prevents damage to the head caused by excessive pressure.

[0057] Embodiment Two

[0058] During actual use, wearing VR glasses will cause long-term compression on the human head, resulting in discomfort, reduced use comfort, and even affecting physical health.

[0059] To solve the above technical problems, as Figures 1 to 6 shown, in another embodiment of the present invention, an auxiliary pressure component 5 is provided on the positioning member 3. The auxiliary pressure component 5 includes a plurality of articulated pressure application members 51 and an air charging and discharging device 55 for driving the pressure application members 51 to fit the head.

[0060] The VR glasses have a rotation mechanism of three working states:

[0061] First state: The top connection component 4 is tightened, the auxiliary pressure component 5 is away from the head, and the pressure is concentrated on the device main body 1, the positioning member 3 and the top connection component 4;

[0062] Second state: The top connection component 4 is relaxed, the auxiliary pressure component 5 fits the head, and the pressure is shared by the device main body 1, the positioning member 3 and the auxiliary pressure component 5;

[0063] Third state: The top connection component 4 is relaxed, the auxiliary pressure component 5 is separated from the head, and the pressure is transferred to the device main body 1, the positioning member 3 and the side connection member 2.

[0064] The switching of the three working states is controlled by a program, automatically triggered according to the usage time, ambient temperature or user's head shape, and the fitting stability between the device and the head is maintained during the state switching.

[0065] In this embodiment, the pressure application member 51 close to the positioning member 3 in the auxiliary pressure component 5 is connected to the positioning member 3. There are a plurality of pressure application members 51, and each two pressure application members 51 are articulated by a rotating shaft 52.

[0066] It should be noted that the pressure application member 51 closest to the positioning member 3 is fixedly connected to the positioning member 3, and the other pressure application members 51 extend in sequence towards the direction close to the device main body 1; the setting of the auxiliary pressure component 5 balances the weights of the device main body 1 and the positioning member 3, preventing the neck health from being affected due to the excessive weight of the device main body 1.

[0067] In this embodiment, a rotating member 53 is provided between every two pressing members 51. A piston rod 531 is provided inside the rotating member 53. The rotating member 53 is connected to one pressing member 51, and the piston rod 531 is connected to the other pressing member 51. The piston head of the piston rod 531 slides inside the rotating member 53, and the rod portion of the piston rod 531 passes through the rotating member 53. A third elastic member 532 is sleeved outside the piston rod 531. One end of the third elastic member 532 is connected to the rotating member 53, and the other end is connected to the pressing member 51.

[0068] An air vent pipe 54 is provided on the rotating member 53. One end of the air vent pipe 54 communicates with the inside of the rotating member 53, and the other end is connected to an air charging and discharging device 55. The air charging and discharging device 55 is connected to the positioning member 3. A flexible member 56 is provided on the side of the pressing member 51 close to the device body 1.

[0069] It should be noted that multiple rotating members 53 can be connected to one air vent pipe 54. At this time, the pressure inside each rotating member 53 is the same. This setting is used in cooperation with the third elastic member 532 to ensure the synchronous rotation of each rotating shaft 52. And when facing different head shapes, the rotation angles of each rotating member 53 are different. The internal communication of multiple rotating members 53 in cooperation with the third elastic member 532 can fit different head shapes.

[0070] The working state rotation mechanism of the VR glasses is realized in the following way:

[0071] The adjusting member 43 of the top connection assembly 4 controls the retraction and extension of the connection belt 42;

[0072] The telescopic portion 31 in the positioning member 3 adjusts the length of the side connection member 2;

[0073] The air charging and discharging device 55 drives the pressing member 51 of the auxiliary pressing assembly 5 to fit or disengage from the head.

[0074] In this embodiment, it is necessary to analyze the force conditions of the VR glasses. As Figure 7 shown, the force analysis of the device body 1, the positioning member 3, and the top connection assembly 4 is carried out respectively:

[0075] N1 is the pressure exerted on the device body 1 by the head, f1 is the frictional force exerted on the device body 1 by the head, T1 is the tensile force exerted on the device body 1 by the top connection assembly 4, T2 is the tensile force exerted on the device body 1 by the side connection member 2, and G1 is the self-weight of the device body 1;

[0076] T2 + T1·cosα = N1

[0077] f1 + T1·sinα = G1

[0078] N2 is the pressure exerted on the positioning member 3 by the head, f2 is the frictional force exerted on the positioning member 3 by the head, T3 is the tensile force exerted on the positioning member 3 by the top connection assembly 4, T4 is the tensile force exerted on the positioning member 3 by the side connection member 2, and G2 is the self-weight of the positioning member 3;

[0079] T4 + T3·cosβ = N2

[0080] f2 + T3·sinβ = G2

[0081] N3 is the pressure exerted on the top connection assembly 4 by the head, T5 is the tensile force exerted on the top connection assembly 4 by the device body 1, T6 is the tensile force exerted on the top connection assembly 4 by the positioning member 3, and G3 is the self-weight of the top connection assembly 4;

[0082] T5·cosα = T3·cosβ

[0083] G3 + T5·sinα + T6·sinβ = N3

[0084] T2 = T4

[0085] T1 = T5

[0086] T6 = T3

[0087] Regarding the entire VR glasses as a whole for force analysis, the VR glasses are only subject to the force from the head and its own gravity. The reaction forces to these forces are the forces exerted by the VR glasses on the head. Analyzing the forces acting on the head, as Figure 8 shown, where N4, N5, and N6 are the pressures exerted by the VR glasses on the head, and f4 and f5 are the frictional forces exerted by the VR glasses on the head.

[0088] When the auxiliary pressure component 5 is pressed against the human head, N6 will decrease, and the decrease amount is ΔN6. Conducting a force analysis on the VR glasses and the head at this time, as Figure 9 shown, where N7 and N8 are the pressures exerted on the auxiliary pressure component 5 by the head, and N9 and N10 are the pressures exerted by the VR glasses on the head, which are the reaction forces of N7 and N8.

[0089] ΔN6 = N10·cosγ + N9·cosγ

[0090] When the auxiliary pressure component 5 is pressed against the human head, the overall force on the VR glasses remains unchanged, and the force-bearing position of the auxiliary pressure component 5 is increased, that is, the force of N6 is distributed to N9 and N10, thereby reducing the pressure of the VR glasses on the head and alleviating the impact of the VR glasses on the head. At the same time, if the top connection assembly 4 is loosened, N6 will further decrease, and N9 and N10 will jointly share the reduced force.

[0091] In this embodiment, the VR glasses have three working states and can change the working states arbitrarily with the change of working time. The three working states are as follows:

[0092] The first state: The positioning member 3 tightens the side connecting member 2, the top connecting assembly 4 is tightened, the auxiliary pressing assembly 5 is away from the human head, and the contact positions of the device body 1, the positioning member 3 and the top connecting assembly 4 with the human head are the main stress points. At this time, the face is subjected to the pressure N4 and the friction force f4 from the device body 1, the back of the head is subjected to the pressure N5 and the friction force f5 from the positioning member 3, and the top of the head is subjected to the pressure N6 from the top connecting assembly 4.

[0093] The second state: The positioning member 3 tightens the side connecting member 2, the top connecting assembly 4 is in an untightened state, the auxiliary pressing assembly 5 fits the human head, and the contact positions of the device body 1, the positioning member 3 and the auxiliary pressing assembly 5 with the human head are the main stress points. At this time, the face is subjected to the pressure N44 and the friction force f44 from the device body 1, the back of the head is subjected to the pressure N55 and the friction force f55 from the positioning member 3, the top of the head is subjected to the pressure N66 from the top connecting assembly 4 and the pressures N9 and N10 from the auxiliary pressing assembly 5. Among them, N66 is less than N6, and N9 and N10 jointly share the reduced pressure.

[0094] The third state: The positioning member 3 tightens the side connecting member 2, the top connecting assembly 4 is in an untightened state, the auxiliary pressing assembly 5 is away from the human head, and the contact positions of the device body 1 and the positioning member 3 with the human head are the main stress points. At this time, the face is subjected to the pressure N4 and the friction force f4 from the device body 1, the back of the head is subjected to the pressure N5 and the friction force f5 from the positioning member 3, and the pressure of the side connecting member 2 on the ears. In this state, the VR glasses rely on the friction force between the head and the support force of the ears to counteract its own gravity, and the pressure on the ears is too large. Therefore, the duration of the third state is the shortest.

[0095] When wearing the VR glasses, slide the adjusting member 43 in the direction away from the positioning member 3 to increase the length of the top connecting assembly 4. At the same time, adjust the telescopic part 31 to elongate the side connecting member 2, so as to facilitate putting the head into the VR glasses. Then, the adjusting member 43 and the telescopic part 31 are adjusted in the reverse direction, and the winding part 431 on the adjusting member 43 makes fine adjustments to reach a comfortable state. At this time, it is the first state of the VR glasses.

[0096] When changing to the second state, the inflation and deflation device 55 inflates the rotating member 53 through the air pipe 54. The pressure in the rotating member 53 increases, pushing the piston rod 531 to move, so that the pressing member 51 rotates along the rotating shaft 52 towards the direction close to the head. When the auxiliary pressing assembly 5 fits the human head, the inflation and deflation device 55 is closed, and the winding part 431 relaxes the connecting belt 42. At this time, it enters the second state.

[0097] When changing to the third state, the telescopic part 31 in the positioning member 3 is adjusted to make the side connecting member 2 further contract, the inflation and deflation device 55 deflates air to the outside, the auxiliary pressure component 5 is separated from the head, and the winding part 431 relaxes the connecting belt 42 to enter the third state.

[0098] It should be noted that the above three states can be changed in order and arranged at will, and can also be arranged repeatedly. The changes between the three working states of VR glasses are controlled by the program and can be changed at will according to the usage time, viewing content, ambient temperature, etc., in order to protect the head and prevent health problems from occurring due to long-term pressure on the same position.

[0099] The present invention decomposes the pressure on the top of the head by setting the auxiliary pressure component 5 to prevent the situation of long-term pressure on the same position of the head, and the three working states of the VR glasses can be changed at any time. While ensuring the fit between the VR glasses and the head remains unchanged and the viewing effect is guaranteed, the pressure position of the VR glasses on the head can be changed at any time, thereby improving the comfort when using the VR glasses for a long time and preventing the VR glasses from compressing the head for a long time and causing effects on physical and mental health.

[0100] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
