[0036] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-6 The tactile feedback device 100 according to an embodiment of the present invention includes an ultrasonic emitting component 10 and a retractable component 20.

[0037] Specifically, such as Figures 1-6 As shown, the ultrasonic transmitting assembly 10 includes an ultrasonic array platform 11, which has an extended position and a retracted position; a retractable assembly 20 is connected to the ultrasonic transmitting assembly 10 and is used to drive the ultrasonic array platform 11 to change between the extended position and the retracted position.

[0038] The ultrasonic array platform 11 is suitable for mounting other structural components of the ultrasonic transmitting assembly 10, such as the multiple ultrasonic array drivers 14 and multiple ultrasonic transmitters 15 described below, to achieve air-to-air tactile feedback. When the tactile feedback device 100 is in working condition, the ultrasonic array platform 11 is in either the extended or retracted position, meaning it can operate in either position, depending on the application scenario. In this application, taking the ultrasonic array platform 11 in the extended position when the tactile feedback device 100 is in working condition as an example, when the tactile feedback device 100 is not in working condition, the ultrasonic array platform 11 is in the retracted position. When the tactile feedback device 100 switches from the non-working state to the working state, the retractable component 20 drives the ultrasonic array platform 11 from the retracted position to the extended position. When the tactile feedback device 100 needs to switch from the working state to the non-working state, the retractable component 20 drives the ultrasonic array platform 11 from the extended position to the retracted position.

[0039] According to the embodiment of the present invention, the tactile feedback device 100, by setting an ultrasonic array platform 11 with an extended position and a retracted position, can ensure the stability of the installation of the ultrasonic transmitting component 10, without affecting the effective transmission and propagation of ultrasonic waves. In the extended position, it provides a stable working plane for other structural components of the ultrasonic transmitting component 10. In the retracted position, it can improve the compactness of the tactile feedback device 100 and effectively reduce the space occupied by the tactile feedback device 100. The retractable component 20 drives the ultrasonic array platform 11 to change between the extended position and the retracted position, which facilitates the foldable design of the tactile feedback device 100 to adapt to different usage scenarios, meet different user needs, improve the flexibility and applicability of the tactile feedback device 100, and allow users to choose whether to use the ultrasonic array platform 11 in the extended position or the retracted position according to their needs.

[0040] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the ultrasonic array platform 11 includes: a first array platform 12 and a plurality of second array platforms 13. The first array platform 12 is connected to a retractable component 20. The plurality of second array platforms 13 are disposed on the outer periphery of the first array platform 12 and are connected to the retractable component 20. The retractable component 20 can selectively drive at least one of the plurality of second array platforms 13 to rotate and connect with the first array platform 12.

[0041] In this embodiment, the first array platform 12 along Figure 2A second array platform 13 is provided on at least one side of the first array platform 12 in either the first direction A or the second direction B. The second array platform 13 is rotatably connected to the first array platform 12. Optionally, the second array platform 13 may be provided on both sides of the first array platform 12 along the first direction A, or the second array platform 13 may be provided on both sides of the first array platform 12 along the second direction B, or the second array platform 13 may be provided on both sides of the first array platform 12 along the first direction A.

[0042] Taking a second array platform 13 disposed on both sides of a first array platform 12 along a first direction A as an example, multiple second array platforms 13 are rotatably connected to the first array platform 12, with the first direction A and the second direction B being perpendicular to each other. A retractable component 20 is connected to both the second array platform 13 and the first array platform 12, and the retractable component 20 can selectively drive at least one of the multiple second array platforms 13 to form a rotatable connection with the first array platform 12 according to actual needs.

[0043] Therefore, by placing multiple second array platforms 13 on the outer periphery of the first array platform 12, the installation area of ​​the ultrasonic array platform 11 can be increased, thereby increasing the coverage area of ​​the ultrasonic waves, increasing the interaction area, and improving the sensitivity of the response. The retractable component 20 can selectively drive at least one of the multiple second array platforms 13 to rotate and connect with the first array platform 12, which facilitates switching the positions of the multiple second array platforms 13, thereby realizing the switching of the ultrasonic array platform 11 between the extended position and the retracted position.

[0044] According to some embodiments of the present invention, a second array platform 13 is arranged on opposite sides of the first array platform 12 and is connected to the first array platform 12, and moves synchronously.

[0045] During the transition between the expanded and retracted positions of the ultrasonic array platform 11, the second array platform 13, located on both sides of the first array platform 12 along the first direction A, moves synchronously and about... Figure 1 The third direction C is centrally symmetrically arranged, where the third direction C is the height direction of the haptic feedback device 100. Optionally, the second array platform 13, which is arranged opposite to the first array platform 12 along the second direction B, can rotate synchronously relative to the first array platform 12.

[0046] Therefore, by synchronously moving the second array platform 13 arranged on opposite sides of the first array platform 12, the balance and stability of the tactile feedback device 100 can be improved, the reliability of the tactile feedback device 100 can be improved, and the efficiency of the ultrasonic array platform 11 in changing between the extended and retracted positions can be improved.

[0047] According to some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the ultrasonic transmitting assembly 10 includes: multiple ultrasonic array drivers 14 and multiple ultrasonic transmitters 15. The multiple ultrasonic array drivers 14 are respectively disposed on a first array platform 12 and multiple second array platforms 13. The ultrasonic array drivers 14 on the first array platform 12 and the ultrasonic array drivers 14 on the second array platform 13 can be controlled independently. The multiple ultrasonic transmitters 15 are disposed on the corresponding ultrasonic array drivers 14, and the multiple ultrasonic transmitters 15 are arranged in an array on the ultrasonic array drivers 14.

[0048] The first array platform 12 and multiple second array platforms 13 are each equipped with an ultrasonic array driver 14 on the surface away from the retractable component 20 along the third direction C. Each ultrasonic array driver 14 is equipped with multiple ultrasonic transmitters 15 on the surface away from the ultrasonic array platform 11 along the third direction C. The multiple ultrasonic transmitters 15 are arranged in an array on the corresponding ultrasonic array driver 14. The ultrasonic transmitters 15 are the core actuators for realizing air-to-air tactile feedback. Multiple ultrasonic transmitters 15 work together to form an ultrasonic field with tactile perception, which acts on the target area, allowing the user to experience air-to-air tactile sensation. As one of the control centers, the ultrasonic array driver 14 can independently adjust the working state of the corresponding ultrasonic transmitters 15, including parameters such as the ultrasonic emission timing, power, and frequency, to achieve flexible control of the ultrasonic field.

[0049] Therefore, by setting up multiple ultrasonic transmitters 15 to emit ultrasonic waves of specific frequencies, intensities, and phases, users can experience tactile sensations without contact with the air, accurately locate the user's gestures or touch positions, and improve the accuracy and response speed of tactile feedback. By setting up multiple ultrasonic array drivers 14, the ultrasonic field formed by the corresponding multiple ultrasonic transmitters 15 can be accurately controlled, achieving different tactile feedback effects, such as simulating pressing and sliding sensations, thus improving the user experience. At the same time, multiple ultrasonic transmitters 15 can be arrayed on the ultrasonic array driver 14 to form a larger ultrasonic array, making full use of the space on the ultrasonic array driver 14, maximizing the number of ultrasonic transmitters 15, increasing the focusing aperture, and significantly improving the focal sound pressure intensity and focusing accuracy. It can also overcome the non-uniformity of the ultrasonic field emitted by a single array, forming a more stable pressure distribution in the detection plane.

[0050] Optionally, each ultrasonic transmitter 15 is 10mm × 10mm in size, each ultrasonic array driver 14 includes 5 × 5 ultrasonic transmitters 15, each ultrasonic array driver 14 is 50mm × 50mm in size, and a single ultrasonic transmitter 15 can generate a pressure of about 20Pa at a position 30cm above.

[0051] Optionally, multiple ultrasonic array drivers 14 are rigidly connected to corresponding first array platforms 12 and multiple second array platforms 13, respectively.

[0052] According to some embodiments of this utility model, such as Figure 2 As shown, the haptic feedback device 100 further includes at least one gesture recognition device 30, which is disposed among a plurality of ultrasonic transmitters 15 on the first array platform 12, and communicates with the ultrasonic array driver 14.

[0053] The ultrasonic array drive component 14 of the first array platform 12 is provided with a gesture recognition device 30 in the central area. The gesture recognition device 30 is suitable for recognizing user gestures and feeding back information data such as the user's position and posture to the control system in the vehicle, so that the tactile feedback device 100 can dynamically adjust the parameters of the ultrasonic field according to the actual situation, thereby improving the accuracy and adaptability of the air-to-air tactile feedback and enhancing the precision and reliability of the tactile feedback device 100.

[0054] Optionally, the gesture recognition device 30 is a binocular camera.

[0055] According to some embodiments of this utility model, such as Figure 3 As shown, the retractable component 20 includes: a first retractable component 21, one end of which is rotatably connected to the second array platform 13 for driving the second array platform 13 to rotate relative to the first array platform 12.

[0056] In this application, taking the second array platform 13 being disposed on both sides of the first array platform 12 along only the first direction A as an example, the retractable component 20 includes two first retractable components 21 symmetrical about the third direction C. The ends of the two first retractable components 21 adjacent to the ultrasonic array platform 11 are respectively rotatably connected to the second array platforms 13 disposed on opposite sides of the first array platform 12. The first retractable components 21 can drive the corresponding second array platform 13 to rotate clockwise or counterclockwise relative to the first array platform 12. Thus, by setting the first retractable components 21, it is convenient to drive the second array platform 13 to rotate relative to the first array platform 12, thereby facilitating the transformation of the ultrasonic array platform 11 between the extended and retracted positions and improving the flexibility of the tactile feedback device 100.

[0057] According to some embodiments of this utility model, such as Figure 3 As shown, a toothed groove 131 is formed on one side of the second array platform 13 adjacent to the retractable component 20. The toothed groove 131 extends from one end of the second array platform 13 connected to the first array platform 12 to the other end away from the first array platform 12. The ultrasonic transmitting component 10 also includes a rack, which slides with the toothed groove 131 and is rotatably connected to the first retractable component 21.

[0058] The second array platform 13 has a toothed groove 131 on one side adjacent to the retractable component 20. The toothed groove 131 is open in the direction of the third direction C toward the retractable component 20, and extends along the first direction A and / or the second direction B. The specific extension direction is determined according to the position of the second array platform 13. Taking the second array platform 13 as being located on both sides of the first array platform 12 along the first direction A as an example, the toothed groove 131 of the second array platform 13 extends along the first direction A, and the rack can move in the toothed groove 131 along the first direction A. The retractable component 20 is connected to the rack at one end adjacent to the second array platform 13. When the ultrasonic array platform 11 moves between the extended position and the retracted position, the retractable component 20 moves between the two ends of the toothed groove 131 along the first direction A through the rack rotatably connected to it, causing the second array platform 13 to rotate relative to the first array platform 12.

[0059] Therefore, by forming a toothed groove 131 on the second array platform 13, it is convenient to limit and fasten the first telescopic component 21. When the ultrasonic array platform 11 is in the extended position, the toothed groove 131 can achieve initial limiting through the meshing of the rack and the toothed groove 131, preventing the second array platform 13 from rotating excessively, thus improving the stability of the ultrasonic array platform 11. At the same time, it ensures that the ultrasonic array platform 11 switches smoothly between the extended and retracted positions, thereby improving the stability and reliability of the tactile feedback device 100.

[0060] According to some embodiments of this utility model, such as Figure 1 As shown, the first telescopic component 21 includes a first driving member 22 and a first telescopic member 23. One end of the first telescopic member 23 is connected to the first driving member 22, and the other end of the first telescopic member 23 is rotatably connected to the rack.

[0061] The end of the first telescopic member 23 furthest from the second array platform 13 is connected to the first driving member 22, and the other end of the first telescopic member 23 adjacent to the second array platform 13 forms a rigid rotational connection with the rack. The first driving member 22 is adapted to drive the first telescopic member 23 to perform telescopic movement. The first telescopic member 23 switches between an extended state and a retracted state, thereby driving the second array platform 13 to move, causing the ultrasonic array platform 11 to switch between an extended position and a retracted position. When the ultrasonic array platform 11 is in the extended position, the first telescopic member 23 is in the extended state; when the ultrasonic array platform 11 is in the retracted position, the first telescopic member 23 is in the retracted state. During the rotation of the second array platform 13, the rack moves within the toothed groove 131, and the end of the first telescopic member 23 furthest from the first driving member 22 is rotatably connected to the rack.

[0062] Thus, the first driving member 22 provides power for the first telescopic component 21 to drive the second array platform 13 to rotate relative to the first array platform 12, thereby improving the stability and flexibility of the ultrasonic array platform 11 in the extended and retracted positions. At the same time, the first telescopic member 23 provides support for the second array platform 13 when the ultrasonic array platform 11 is in the extended position.

[0063] Optionally, the first driving component 22 is a drive motor.

[0064] According to some embodiments of this utility model, such as Figure 3 As shown, the retractable component 20 further includes a second retractable component 24, one end of which is connected to the first array platform 12, and the other end of the first retractable component 21 is rotatably connected to the second retractable component 24. The second retractable component 24 is used to drive the ultrasonic array platform 11 to move toward or away from the other end of the second retractable component 24.

[0065] The second telescopic component 24 extends along a third direction C, and one end of the second telescopic component 24 adjacent to the ultrasonic array platform 11 along the third direction C is rigidly connected to the first array platform 12 by bolts. The first telescopic component 21 is located on both sides of the second telescopic component 24 along a first direction A, and the other end of the first telescopic component 21 away from the second array platform 13 is rotatably connected to the second telescopic component 24. When the first telescopic component 21 rotates clockwise or counterclockwise, the second array platform 13 can move toward or away from the second telescopic component 24, thereby realizing the switching of the ultrasonic array platform 11 between the retracted position and the extended position. The end of the second telescopic component 24 connected to the first array platform 12 can move toward or away from the other end of the second telescopic component 24 along the third direction C, thereby driving the ultrasonic array platform 11 to move toward or away from the other end of the second telescopic component 24 along the third direction C.

[0066] Therefore, by setting the second telescopic component 24, it is convenient to adjust the overall height of the tactile feedback device 100, thereby adapting to the needs of different usage heights and improving the effectiveness of tactile feedback. The second telescopic component 24 can provide support for the ultrasonic array platform 11, ensuring the stability of the tactile feedback device 100 when adjusting its height. The other end of the first telescopic component 21 is rotatably connected to the second telescopic component 24, providing an installation position for the first telescopic component 21 and facilitating the rotation of the first telescopic component 21, thereby facilitating the movement of the second array platform 13 toward or away from the second telescopic component 24.

[0067] According to some embodiments of this utility model, such as Figure 1As shown, the second telescopic component 24 includes a second driving member 25 and a second telescopic member 26. One end of the second telescopic member 26 is connected to the second driving member 25, and the other end of the second telescopic member 26 is connected to the first array platform 12.

[0068] The second telescopic member 26 is disposed between the first array platform 12 and the second driving member 25, and the two ends of the second telescopic member 26 along the third direction C are respectively connected to the first array platform 12 and the second driving member 25. The second driving member 25 is adapted to drive the second telescopic member 26 to perform telescopic movement along the third direction C. The second telescopic member 26 switches between the contracted state and the extended state, which can drive the first array platform 12 to move towards or away from the second driving member 25 along the third direction C. When the ultrasonic array platform 11 is in the unfolded position, the second telescopic member 26 is in the extended state. When the ultrasonic array platform 11 is in the contracted position, the second telescopic member 26 is in the contracted state.

[0069] Thus, through the setting of the second driving member 25, the second telescopic component 24 provides power to drive the ultrasonic array platform 11 to move toward or away from the other end of the second telescopic component 24, thereby improving the flexibility of the ultrasonic array platform 11 in the extended and retracted positions. At the same time, through the setting of the second telescopic member 26, it provides support for the first array platform 12, making it easier to adjust the overall height of the tactile feedback device 100.

[0070] Optionally, the second drive component 25 needs to have sufficient strength and rigidity to withstand the weight of the second telescopic component 26 and the ultrasonic array platform 11, as well as the mechanical load when the tactile feedback device 100 is working, so as to ensure the structural stability of the tactile feedback device 100 at different heights and postures. The second drive component 25 is a drive motor.

[0071] According to some embodiments of the present invention, in the process of the ultrasonic array platform 11 changing from the retracted position to the extended position, the second telescopic component 24 moves first, followed by the first telescopic component 21; in the process of the ultrasonic array platform 11 changing from the extended position to the retracted position, the first telescopic component 21 moves first, followed by the second telescopic component 24.

[0072] Specifically, when the ultrasonic array platform 11 changes from the retracted position to the extended position, the second drive member 25 of the second telescopic component 24 is activated first, so that the second telescopic member 26 drives the ultrasonic array platform 11 to move away from the second drive member 25 along the third direction C, increasing the height of the tactile feedback device 100 along the third direction C, reserving a suitable space height for the subsequent movement of the second array platform 13, and ensuring that the components will not interfere due to space constraints. Subsequently, the first drive member 22 of the first telescopic component 21 drives the first telescopic member 23 to rotate and extend towards the first array platform 12. The first telescopic member 23 pushes the second array platform 13 to move away from the second telescopic member 26, so that the ultrasonic array platform 11 gradually unfolds along the first direction A. The meshing of the toothed groove 131 and the rack achieves initial positioning to prevent the second array platform 13 from rotating excessively. At the same time, multiple ultrasonic array drive members 14 and multiple ultrasonic transmitters 15 adjust their positions synchronously with the unfolding of the ultrasonic array platform 11, gradually forming a complete ultrasonic transmitting array layout, preparing for the air-to-air tactile feedback function.

[0073] When the ultrasonic array platform 11 changes from the unfolded position to the retracted position, the first drive member 22 first drives the first telescopic member 23 to rotate and retract in a direction away from the first array platform 12. The toothed groove 131 disengages from the rack and is limited. The first telescopic member 23 drives the second array platform 13 to move toward the second telescopic member 26, so that the ultrasonic array platform 11 gradually folds along the first direction A. Then the second drive member 25 is activated, so that the second telescopic member 26 drives the ultrasonic array platform 11 to move along the third direction C toward the second drive member 25, reducing the overall height of the tactile feedback device 100 along the third direction C and improving the compactness of the tactile feedback device 100.

[0074] In this application, the components of the haptic feedback device 100 work together to achieve an efficient and stable unfolding and folding process, which meets the usage requirements of the haptic feedback device 100 in different scenarios and provides structural support for the flexible deployment of the air-to-air haptic feedback function. It not only ensures the effective layout of the ultrasonic transmitting array in the working state, but also can be retracted and stored when not in operation, thereby improving the spatial adaptability of the haptic feedback device 100.

[0075] Optionally, the first telescopic component 21 and the second telescopic component 24 move synchronously. This facilitates the rapid switching of the ultrasonic array platform 11 between the extended and retracted positions, improves the efficiency of the haptic feedback device 100 in unfolding or folding, and further enhances the convenience of the haptic feedback device 100.

[0076] According to some embodiments of this utility model, such as Figure 1As shown, the ultrasonic array platform 11 is in the deployed position, and the first array platform 12 and the second array platform 13 are arranged in parallel. When the ultrasonic array platform 11 is in the deployed position, the first array platform 12 and the second array platform 13 are aligned along the first direction A. This allows for a wider range of tactile feedback coverage, improves the tactile effect, increases the interactive area, and provides a more uniform and delicate tactile experience.

[0077] Optionally, such as Figure 6 As shown, the ultrasonic array platform 11 is in the retracted position, and the first array platform 12 and the second array platform 13 are arranged perpendicularly. When the second array platform 13 gradually moves towards the second telescopic member 26 until the angle between the first array platform 12 and the second array platform 13 is 90°, the second array platform 13 stops moving, and the ultrasonic array platform 11 is in the retracted position. This improves the compactness of the haptic feedback device 100, reduces the space occupied by the haptic feedback device 100, and facilitates its storage.

[0078] According to some embodiments of this utility model, such as Figure 2 As shown, the haptic feedback device 100 further includes a hinge structure 31, which is disposed between the first array platform 12 and the second array platform 13. The second array platform 13 can be rotatably connected to the first array platform 12 via the hinge structure 31, thereby enabling the ultrasonic array platform 11 to switch between an extended position and a retracted position. Thus, the hinge structure 31 improves the flexibility and reliability of the rotation of the second array platform 13 relative to the first array platform 12. Furthermore, a ±90° physical limiting groove is provided at the hinge point of the first array platform 12 and the second array platform 13 to prevent excessive rotation of the second array platform 13 from causing cable entanglement or structural interference, thereby improving the safety and reliability of the haptic feedback device 100.

[0079] Optionally, such as Figure 4 and Figure 5 As shown, a hinge structure 31 is disposed between the ultrasonic transmitting assembly 10 and the telescopic assembly 20. The hinge structure 31 is also disposed between the first telescopic assembly 21 and the second telescopic assembly 24, and the first and second telescopic assemblies 21 and 24 are rotatably connected via the hinge structure 31. The first telescopic assembly 21 can be rotatably connected to the second telescopic assembly 24 via the hinge structure 31, thereby facilitating the rotation of the second array platform 13 relative to the first array platform 12. Therefore, the hinge structure 31 improves the flexibility and reliability of the rotation of the first telescopic assembly 21 relative to the second telescopic assembly 24.

[0080] In this application, the hinge structure 31 is disposed between the first array platform 12 and the second array platform 13, and also between the first telescopic component 21 and the second telescopic component 24. This further improves the flexibility and reliability of the ultrasonic array platform 11 in switching between the extended and retracted positions. Simultaneously, the hinge structure 31 possesses certain load-bearing and fatigue resistance properties, ensuring the reliability of the tactile feedback device 100 after multiple folding and unfolding operations, and extending the service life of the tactile feedback device 100.

[0081] Optionally, the hinge structure 31 is disposed between the first array platform 12 and the second array platform 13, and between the first telescopic assembly 21 and the second telescopic assembly 24, via spring pins. This improves the installation efficiency of the hinge structure 31, facilitates its maintenance and replacement, and makes the haptic feedback device 100 easier to install and disassemble, enhancing user convenience.

[0082] According to a second aspect embodiment of the present invention, the vehicle includes a center armrest and a haptic feedback device 100. The haptic feedback device 100 is any of the haptic feedback devices described in the above embodiments, and is located in the center armrest. In the dynamic environment inside the vehicle, the haptic feedback device 100 can better adapt to space constraints and user movement needs, adapt to dynamic conditions such as vibration and temperature changes inside the vehicle, and provide a stable haptic feedback experience. Furthermore, the foldable design of the haptic feedback device 100 can adapt to different in-vehicle scenarios, such as being deployed on different seats or having its shape adjusted according to user needs, thus improving the flexibility of the haptic feedback device 100's placement.

[0083] Optionally, for in-vehicle scenarios, the haptic feedback device 100 can be flexibly deployed on the steering wheel, center console, or seats to meet the haptic feedback needs of different users. The haptic feedback device 100 can be integrated with the in-vehicle system to provide navigation prompts, safety warnings, and other functions, thereby improving driving safety and enjoyment and enhancing the user's driving experience.

[0084] According to some embodiments of the present invention, the central armrest box is provided with a mounting groove, the tactile feedback device 100 is provided in the mounting groove, the ultrasonic array platform 11 of the tactile feedback device 100 moves from the retracted position to the extended position, the tactile feedback device 100 extends out of the mounting groove, the ultrasonic array platform 11 moves from the extended position to the retracted position, and the tactile feedback device 100 retracts into the mounting groove.

[0085] The tactile feedback device 100 is housed in the mounting slot, and the second telescopic component 24 is fixedly connected to the bottom wall of the mounting slot to ensure the stability of the tactile feedback device 100 during lifting and operation, and to resist vibration interference during vehicle movement. When the ultrasonic array platform 11 changes from the retracted position to the extended position, the second telescopic component 24 drives the tactile feedback device 100 to extend out of the mounting slot, and the first telescopic component 21 drives the ultrasonic array platform 11 to gradually extend along the first direction A. The ultrasonic array platform 11 covers the upper and surrounding reasonable area of ​​the center armrest box, and the height of the ultrasonic array platform 11 matches the operating range of the driver and passengers' hands, so that the tactile feedback signal can effectively act on the target area and ensure that the ultrasonic field energy acts on the frequently used operating hand space of the driver and passengers. When the ultrasonic array platform 11 changes from the extended position to the retracted position, the first telescopic component 21 drives the ultrasonic array platform 11 to gradually fold along the first direction A, and the second telescopic component 24 drives the tactile feedback device 100 to retract into the mounting slot, reducing the space occupied by the tactile feedback device 100 and making reasonable use of the idle space of the mounting slot without affecting the conventional storage functions of the center armrest box.

[0086] Optionally, when the ultrasonic array platform 11 is in the unfolded position, the ultrasonic array platform 11 is positioned at a suitable height and horizontal position above the center armrest box, with its surface facing the area where the driver and passengers can operate their hands. The edge of the ultrasonic array platform 11 maintains a reasonable gap with the interior trim around the center armrest box, so as not to interfere with the original decoration and operation of the vehicle, while allowing the ultrasonic field to effectively cover the target interaction space, realize the function of tactile feedback without air, such as simulating the touch of buttons, touch feedback, etc., and improve the human-computer interaction experience in the vehicle.

[0087] According to some embodiments of the present invention, the ultrasonic array platform 11 is located in the retracted position, and the ultrasonic array platform 11 is flush with the surface of the central armrest box; or, the ultrasonic array platform 11 is located in the mounting groove.

[0088] When the ultrasonic array platform 11 is in the retracted position, the second telescopic component 24 drives the ultrasonic array platform 11 to descend, causing the tactile feedback device 100 to retract into the mounting groove. At this time, the ultrasonic array platform 11 is flush with the interior surface of the center armrest box or hidden in the mounting groove of the center armrest box, restoring the normal use scenario of the center armrest box area without affecting the normal use of cup holders, storage compartments and other functions.

[0089] Optionally, the mounting slot has an opening along the height direction facing the driver and passengers, and a mounting cover is provided at the opening. The mounting cover can open or close the opening so that the haptic feedback device 100 can extend or retract into the mounting slot, preventing other items in the vehicle from falling into the mounting slot. At the same time, it is convenient to further hide the haptic feedback device 100 and improve the aesthetics.
