[0053] To more clearly illustrate the present invention, the following description, in conjunction with embodiments and accompanying drawings, further explains the invention. Similar components in the drawings are indicated by the same reference numerals. Those skilled in the art should understand that the specific description below is illustrative rather than restrictive and should not be construed as limiting the scope of protection of the present invention.

[0054] One embodiment of the present invention provides an odor emission device and a VR display device.

[0055] like Figures 1 to 13 As shown, one embodiment of the present invention provides an odor emission device applied to a VR display device, including: a control module 10, a transmission module 20, and at least one odor storage module 30.

[0056] The control module 10 is used to output odor commands according to the display screen. For example, the control module 10 is a CPU, server, etc.

[0057] The transmission module 20 is used to control the use of the odor storage module 30 to open according to the odor command, so that the use of the odor storage module emits odor.

[0058] In this embodiment, the control module analyzes the image displayed on the VR display device, generates an odor command corresponding to the current display image, and activates the corresponding odor storage module through the power transmission module. This enables the odor storage module to release the odor materials it stores. This embodiment applies odor release functionality to the VR display device, achieving high integration and enabling linkage with touch or odor to enhance the user experience, thus possessing broad application prospects.

[0059] In an optional embodiment, the structural schematic diagram of the odor emission device of this embodiment is shown below. Figure 2 As shown and Figure 3 As shown, the odor emission device also includes a housing 40, the odor storage module 30 is disposed inside the housing 40, and the housing 40 has an odor outlet 41.

[0060] like Figure 3 As shown in the top view, the housing 40 is provided with multiple odor outlets 41, and each odor outlet 41 is provided with an odor storage module 30. In response to an odor command, the odor storage module 30 is pushed out from the corresponding odor outlet 41, that is, it moves in the direction of facing outwards towards the paper. The remaining odor storage modules 30 that are not in use remain in their original closed state.

[0061] like Figure 2 As shown, the odor storage module 30, control module 10, and transmission module 20 are all housed inside the housing 40, forming a complete odor emission device that is easy to move and install. For example, as shown... Figure 2 As shown, a blocking member 42 is provided between adjacent odor storage modules 30. On the one hand, it limits the movement of the odor storage material, so that the odor storage material moves linearly in the vertical direction. On the other hand, it avoids crosstalk between different odors.

[0062] like Figure 2 As shown, the transmission module 20 includes:

[0063] The lifting unit 21, which is fixedly connected to the odor storage module 30, is exemplarily capable of […]. Figure 2 The vertical movement is shown; and

[0064] The first drive unit 22 is used to activate in response to the odor command and drive the lifting unit 21 to move along the lifting direction to push the odor storage module 30 out of the odor outlet 41.

[0065] For example, when there is a corresponding odor in the display screen that needs to be emitted by the odor emission device, the first drive unit 22 is activated in response to the odor command of the control module 10. The first drive unit 22 provides power to the lifting unit 21. The lifting unit 21 connected to the first drive unit 22 moves vertically under its drive. At the same time, under the drive of the lifting unit 21, the odor storage module 30 connected to the lifting unit 21 is pushed out from the odor outlet 41. The pushed-out odor storage module 30 emits the odor into the space of the VR display device.

[0066] In one specific example, the surface of the housing 40 with the odor outlet 41 is relatively close to the user, for example, 0.5 to 1 meter away. This means the odor outlet 41 is close to the user's nose, allowing the odor material to be released after being pushed out using the lifting unit 21. In an optional embodiment, the surface of the housing 40 with the odor outlet 41 is positioned at a higher height in the lifting direction than the surface of the odor storage module 30 adjacent to the odor outlet 41. That is, when the odor storage module 30 is not in use, it is completely housed inside the housing 40, preventing the odor from dissipating to the user when not in use.

[0067] In an optional embodiment, such as Figure 4 As shown, the transmission module 20 further includes an airflow transmission unit 23 connected to the odor storage module 30, used to control the opening of the airflow channel with the odor storage module 30 according to the odor command, so that the odor from the odor storage module 30 is dispersed into the space of the VR display device by the airflow. In this embodiment, the airflow transmission unit 23 is used to assist in the dispersion of the odor from the odor storage module 30, thereby further increasing the range of the odor emitted by the odor storage module 30.

[0068] In an optional embodiment, the airflow transmission unit 23 includes:

[0069] The second drive unit 231 is used to generate airflow in response to the odor command. For example, the second drive unit 231 is a drive air pump, and an air inlet 44 is provided on the housing 40 corresponding to the drive air pump 231. The air inlet 44 and the drive air pump 231 form an air intake channel. In one example, a filter 43 is also provided between the air inlet 44 and the air intake channel of the drive air pump 231 to filter the air and ensure airflow quality.

[0070] The connecting pipe 232 is connected at one end to each of the odor storage modules 30 and at the other end to the second driving unit 231;

[0071] A control valve 233 is provided on each of the connecting pipes 232 to open the airflow channel of the odor storage module 30 in use according to the odor command.

[0072] like Figure 4 As shown, this embodiment includes multiple odor storage modules 30, with connecting pipes 232 corresponding to each odor storage module 30. One end of each connecting pipe 232 is connected to each odor storage module 30, and the other end is connected to the second drive unit 231, used to transmit the airflow generated by the second drive unit 231 to the odor storage module 30 through the connecting pipe 232. By setting a control valve 233 on each connecting pipe 232, the state of the connecting pipe 232 is controlled. When the control valve 233 opens in response to an odor command, the connecting pipe 232 is in a conducting state, and the airflow is directly transmitted from the second drive unit 231 to the odor storage module 30, diffusing the odor from the odor storage module 30 into the space of the VR display device for the user to smell, thus improving the interactive experience.

[0073] In an optional embodiment, such as Figure 4 As shown, each of the airflow ducts includes:

[0074] The first connecting pipe 2321 connecting the control valve 233 and the odor storage module 30; and

[0075] A second connecting pipe 2322 connects the control valve 233 and the second drive unit 231, and multiple second connecting pipes 2322 are located in the same connecting pipe 232.

[0076] In this embodiment, the first connecting pipe 2321 connecting the control valve 233 and the odor storage module 30 is set independently to ensure the accuracy of control of each odor storage module 30. Furthermore, in this embodiment, the second connecting pipe 2322 connecting the control valve 233 and the second drive unit 231 is set to be shared, that is, the airflow generated by the second drive unit 231 can be transmitted to each second connecting pipe 2322, and the control valve 233 is used to open or close the airflow channel. This setting can simplify the structure of the device and reduce the space occupied.

[0077] In an optional embodiment, such as Figure 4 As shown, the lifting unit 21 includes:

[0078] The support member 211 is disposed on the side of the odor storage module 30 away from the odor outlet 41;

[0079] The transmission component 212 has one end connected to the support component 211 and the other end connected to the first drive unit 22 located on the side of the support component 211 away from the odor storage module 30. Under the drive of the first drive unit 22, the support frame is moved vertically.

[0080] In this embodiment, the transmission component 212 has a lifting and telescopic function. Under the drive of the first driving unit 22, the transmission component 212 moves... Figure 4 The vertical linear movement shown drives the carrier 211, which is fixed to the odor storage module 30, to move in the same direction, thereby causing the odor storage module 30 to be pushed out or retracted from the odor outlet 41. By utilizing the carrier 211, the transmission component 212, and the cooperation with the first drive unit 22, the odor storage module 30 is moved to diffuse the odor.

[0081] In an optional embodiment, such as Figure 4 As shown, in this embodiment, there are multiple odor storage modules 30. The number of first drive units 22 and lifting units 21 is the same as the number of odor storage modules 30. That is, when the first drive unit 22 corresponds one-to-one with the odor storage module 30, the lifting unit 21 corresponds one-to-one with the first drive unit 22, and the odor outlet 41 corresponds one-to-one with the odor storage module 30. In other words, one first drive unit 22 is connected to one lifting unit 21, and one lifting unit 21 is connected to one odor storage module 30. The carrier 211 and transmission 212 in the lifting unit 21 correspond one-to-one with either the odor storage module 30 or the first drive unit 22. In this structure, the odor storage modules 30 are driven independently. Under the odor command, each first drive unit 22 drives the corresponding transmission 212 to make the odor storage module 30 corresponding to the carrier 211 move linearly in the lifting direction, realizing independent control of the odor storage module 30.

[0082] In another alternative embodiment, such as Figure 5 As shown, the orthographic projection of the carrier 211 in the lifting direction covers the orthographic projection of the odor storage module 30 in the lifting direction. In this embodiment, in the lifting direction, i.e., the vertical direction, the orthographic projections of all the odor storage modules 30 fall on the orthographic projection of the carrier 211 in that direction. That is, the carrier 211 is an integral structure, and one carrier 211 can connect all the odor storage modules 30, realizing the overall movement of all the odor storage modules 30.

[0083] In this structure, the transmission components 212 are symmetrically arranged at both ends of the bearing component 211, for example, as shown in the example. Figure 5As shown, the transmission component 212 is disposed at the left and right ends of the bearing component 211. The first driving unit 22 is connected to the transmission component 212 and drives the transmission component 212 to make the bearing component 211 move all the odor storage modules 30 in the vertical direction, providing a balanced driving force for the bearing component 211, so that the odor storage modules 30 can move in a balanced linear motion in the vertical direction.

[0084] In other words, the embodiments of the present invention can either choose the design method in which the first driving unit 22, the lifting unit 21 and the odor storage module 30 correspond one-to-one, or choose the design method in which one lifting unit 21 corresponds to multiple odor storage modules 30. The embodiments of the present invention do not limit this.

[0085] In an optional embodiment, such as Figures 3-5 As shown, the odor storage module 30 includes:

[0086] The support frame 31 connected to the lifting unit 21 has a length in the vertical direction that is greater than the transmission distance of the transmission member 212 in the vertical direction.

[0087] A fixing bracket 32 ​​is provided on the surface of the support frame 31 near the odor outlet 41; and

[0088] Storage box 33 for containing odor material is disposed on the surface of the mounting bracket 32 ​​near the odor outlet 41.

[0089] One side surface of the fixed frame 32 is fixedly connected to the storage box 33, and the other side surface is fixed to the support frame 31. The side surface of the fixed frame 32 and the support frame 31 forms a transmission space. The transmission component 212 moves up and down within this transmission space. In this embodiment, the length of the support frame 31 is greater than the transmission distance of the transmission component 212 in the vertical direction, so as to reserve transmission space for the movement of the transmission component 212 in the vertical direction and avoid interference between the support frame 31 and the transmission component 212.

[0090] In an optional embodiment, such as Figure 6 As shown, the storage box 33 includes a box body 331, a cover plate 332 that cooperates with the box body 331, and an odor material plate 333 disposed between the box body 331 and the cover plate 332. For example, the box body 331 is provided with a groove structure for placing the odor material plate 333. In an optional embodiment, the odor material plate 333 is solid, effectively preventing leakage of the odor material.

[0091] The box body 331, the cover plate 332, and the scent material plate 333 are fixed by magnetic force. For example, the three can be fixed by magnetic attraction plate 334, which makes it easy to replace different scent material plates 333.

[0092] The cover plate 332 shown is provided with an air vent 335 or an odor valve 336 to reduce the influence between the various odor storage modules 30.

[0093] For example, such as Figure 6 As shown, vent holes 335 are provided at corresponding positions of the odor material plate 333 and the cover plate 332. In one specific example, when the odor dispersing device is close to the user, after the odor storage module 30 is pushed out from the odor outlet 41, the odor is directly dispersed into the space of the VR display device through the vent holes 335 for the user to smell. In another specific example, when the odor dispersing device generates airflow through the airflow transmission unit 23, the airflow carries the odor of the odor material and disperses it into the space of the VR display device through the vent holes.

[0094] For example, such as Figure 7 As shown, an odor valve 336 is provided on the cover plate 332 to further reduce the influence between different odor materials. In one specific example, when the odor valve 336 is open and the odor dispersing device is close to the user, the odor is directly dispersed into the space of the VR display device through the odor valve 336 for the user to smell. In another specific example, when the odor valve 336 is open and the odor dispersing device generates airflow through the airflow transmission unit 23, the airflow carries the odor of the odor material and disperses it into the space of the VR display device through the odor valve.

[0095] For example, the odor valve can be a shape memory alloy, a MEMS valve structure, etc.

[0096] In an optional embodiment, the odor valve 336 disposed on the cover plate 332 and the control valve 233 disposed on the pipeline are pressure-responsive check valves. For example, when the odor storage module 30 to be used is determined according to an odor command, the odor valve 336 of the odor storage module 30 opens, forming an airflow at the odor outlet 41. At this time, as... Figure 8 As shown, the control valve 233 corresponding to the odor storage module 30 opens according to the airflow change, and the airflow channel corresponding to the odor storage module 30 opens. The airflow generated by the first drive unit 22 is guided into the odor storage module 30 to further disperse the odor.

[0097] For example, such as Figure 9 and Figure 10As shown, the pressure-responsive one-way valve can be a tricuspid valve-like structure or a folded structure. When airflow passes through, the valve's valve structure opens, allowing airflow to be transmitted through the conducting airflow channel to the odor storage module 30. In another example, when airflow passes through, the folded valve's airflow-driven folding structure opens, exposing an odor orifice, thereby enabling odor transmission.

[0098] Unlike the method in the previous embodiment where the lifting unit 21 moves linearly in the vertical direction to eject the odor storage module 30, this embodiment proposes another method for ejecting the odor storage module 30, such as... Figure 11 As shown, in an optional embodiment, the transmission module 20 further includes:

[0099] The rotating unit 24, which is fixedly connected to the odor storage module 30, and

[0100] A third drive unit 25, electrically connected to the control module 10, is used to activate in response to the odor command and drive the rotation unit 24 to rotate the odor storage module 30 from inside the housing 40 to outside the housing 40.

[0101] In this embodiment, as Figure 11 As shown, the third drive unit 25 is a drive motor, and the odor storage module 30 is connected to the drive motor via a rotating unit 24. The rotating unit 24 includes a transmission component 212, one end of which is connected to the third drive unit 25, and the other end is fixed to the odor storage module 30. In a specific example, the transmission component 212 includes a transmission structure 241, a transmission gear 242, and a fixing frame 32 connected to the transmission gear. The fixing frame 32 is fixedly connected to the odor storage module 30. In a specific example, as shown... Figure 11 In this embodiment, the transmission component 212 is disposed at both ends of the fixed frame 32, and the third drive unit 25 is connected to the transmission component 212 at both ends respectively. The third drive unit 25 drives the two transmission components 212 simultaneously to rotate the fixed frame 32, and the odor storage material located on the fixed frame 32 is also rotated.

[0102] In a specific example, in the initial state, such as Figure 12 As shown, the odor storage module 30 on the mounting bracket 32 ​​is located inside the housing 40. Under the drive of the third drive unit 25, the transmission structure 241 and the transmission gear 242 rotate, causing the mounting bracket 32 ​​to rotate and rotate the odor storage module 30 out of the housing 40. This allows the odor emitted by the odor storage module 30 to flow into the space of the VR display device for the user to smell. The airflow direction emitted by the odor emission device in this embodiment is downward, and the user is located below the airflow, which can improve the user's experience.

[0103] In another specific example, there may be multiple third driving units 25 in this embodiment, see reference. Figure 2 or Figure 4 In the structure shown, the third drive unit 25 corresponds to each odor storage module 30. The corresponding third drive unit 25 and odor storage module 30 are connected by transmission component 212 to realize independent rotation control of each odor storage module 30.

[0104] In an optional embodiment, the odor emitting device further includes an odor absorption module 50 for forming an odor absorption channel to exclude the odor emitted by the odor emitting device from the outside of the VR display device.

[0105] For example, such as Figure 11 and Figure 12 As shown, in an optional embodiment, the odor absorption module 50 is disposed opposite the odor storage module 30. For example, as... Figure 11 and Figure 12 As shown, the odor storage module is mounted on the fixed frame 32. After the odor storage module 30 is rotated, the airflow of the odor storage device flows downward. The odor absorption module is located below the odor storage module 30 and can fully absorb the airflow flowing from top to bottom.

[0106] In another specific example, when the odor emitting device is Figures 2 to 11 In the linear motion structure shown, the odor absorption module 50 of this embodiment includes a fourth drive unit 51, which forms an odor absorption channel with the air inlet 44 and the exhaust port 45 disposed on the housing 40.

[0107] In a specific example, such as Figure 13 As shown, the odor absorption module is housed in the casing 40. The fourth drive unit 51 is an air exchange pump. The odor absorption module 30 uses the air exchange pump to introduce external air from the air inlet 44 and discharge the internal gas mixed with odor through the exhaust port 45, ensuring that the odor perceived by the user is undisturbed and improving the user experience.

[0108] In one specific example, the air inlet 44 and the air outlet 45 are located on the side wall of the housing 40. In another example, the air inlet 44 and the air outlet 45 are disposed on the bottom surface opposite the odor outlet 41, and are also configured to improve ventilation efficiency.

[0109] The technical solution described in this invention outputs the odor command corresponding to the display screen to the transmission module, which then uses the transmission module to cause the odor storage module to emit odor. This application of odor emission function to VR display devices is highly integrated and can be linked with touch or odor to enhance the user experience, thus having broad application prospects.

[0110] Another embodiment of the present invention proposes a VR display device, which includes the odor emission device of the above embodiment, applied in the field of interaction, to enhance the user's experience and has broad application prospects.
