The following is in conjunction with... Figures 1 to 3 Examples illustrate the human-computer interaction device of the present invention and the vehicle-mounted intelligent interaction system using the human-computer interaction device of the present invention.

[0036] like Figure 1 As shown, the human-computer interaction device 10 is used in an in-vehicle intelligent interaction system according to an embodiment of the present invention. It can be used as part of the in-vehicle intelligent interaction system. For example, the human-computer interaction device 10 can be used as a terminal to provide feedback on the response status information of the in-vehicle intelligent interaction system to the user. In one embodiment, the human-computer interaction device 10 can provide feedback or present various response status information of the in-vehicle intelligent interaction system to the user by displaying a halo with varying states, or by displaying a halo with varying states, or by a combination of these (i.e., a combination of displaying a halo and a halo with varying states). In other embodiments, the human-computer interaction device 10 can also receive various information or instructions (e.g., voice instructions) from the user by configuring sensors thereon. It will be understood that the human-computer interaction device 10 can integrate various sensors (e.g., cameras, microphones, and even voiceprint recognition components) to expand the functionality of the human-computer interaction device.

[0037] It should be noted that the in-vehicle intelligent interaction system of the present invention may include various sensors, processors, and various information acquisition / processing components of the vehicle, and may use various interaction technologies, such as voice interaction, gesture interaction, and image interaction; the in-vehicle intelligent interaction system can therefore perform corresponding operations based on the information about the user (such as voice information, gesture information, vehicle operation information, etc.) input during the human-computer interaction process.

[0038] It will be understood that the manner in which the human-computer interaction device 10 uses feedback response status information is not limiting; the response status information can represent the current working state of the in-vehicle intelligent interaction system, for example, response status information corresponding to the working state of processing user A's voice command, response status information corresponding to the working state of processing user B's voice command, response status information corresponding to the working state of processing path planning, response status information corresponding to the working state of being in a sleep state, etc. The response status information can change dynamically with the changes in the working state of the in-vehicle intelligent interaction system, and the specific type or quantity of the response status information is not a limiting change, and may change with the changes in the in-vehicle intelligent interaction system of the present invention (e.g., functional expansion).

[0039] Continue as Figures 1 to 3 As shown, a human-machine interaction device 10 according to an embodiment of the present invention includes a liftable main body 110, which is used to provide feedback to the user on the response status information of the in-vehicle intelligent interaction system, and / or to receive various information or instructions obtained from the user. Its specific external and / or internal structure is not limited to the illustrated embodiment. The human-machine interaction device 10 is fixedly mounted on a base plate 190 in the vehicle's cockpit. Its specific mounting position on the base plate 190 is not limited; for example, it can be installed in a location inside the vehicle where user interaction is convenient. Specifically, the base plate 190 can be integrated with, for example, the vehicle's dashboard and manufactured together. The human-machine interaction device 10 is at least partially exposed relative to the base plate 190, and therefore easily subjected to external forces from the user (e.g., external forces from abnormal pressing operations).

[0040] The human-computer interaction device 10 also includes a drive component 120. The liftable body 110 is placed above the base 150 inside the base plate 190 and is used to drive the liftable body 110 to move up and down in a generally vertical direction. The drive component 120 can be a motor, such as various micro motors, and optionally a linear motor. When a linear motor is selected, it can drive the liftable body 110 to move linearly in the vertical direction.

[0041] In one embodiment, the human-computer interaction device 10 can be recessed and installed in the recessed structure 191 of the substrate 190, for example, by positioning it in the recessed structure 191 of the substrate 190 via the base 150 of the human-computer interaction device 10. Specifically, the state in which the upper surface of the liftable body 110 is substantially flush with the substrate 190 can be defined as the lowest position at which the liftable body 110 can be lowered. The liftable body 110 can rise from this lowest position under the drive of the drive component 120, and of course, it can also descend back to the lowest position under the drive of the drive component 120.

[0042] Continue as Figure 1 As shown, the human-computer interaction device 10 also includes a connecting sleeve assembly 140 placed between the drive component 120 and the liftable body 110. The connecting sleeve assembly 140 can be used to buffer the external force received by the liftable body 110 in the general vertical direction.

[0043] Specifically, such as Figure 2 and Figure 3As shown, the connecting sleeve assembly 140 includes an outer cylinder 141, an inner cylinder 143, and an elastic element 142; wherein the inner cylinder 143 is placed inside the outer cylinder 141, and the elastic element 142 is located between the outer cylinder 141 and the inner cylinder 143. In one embodiment, the outer cylinder 141 includes a first cylinder wall portion 1411 and a second cylinder wall portion 1412, the first cylinder portion 1411 having a larger inner diameter than the second cylinder wall portion 1412; the upper end of the inner cylinder 143 has a flange 1431, the upper end of the elastic element 142 abuts against the flange 1431, and the lower end of the elastic element 142 abuts against the step 1413 between the first cylinder portion 1411 and the second cylinder wall portion 1412. Thus, the elastic element 142 is fitted onto the inner cylinder 143 and is generally positioned within the space surrounded by the flange 1431, the first cylinder portion 1411, the step 1413, and the inner cylinder 143.

[0044] It will be understood that in the structure of the above illustrated embodiment, since the inner cylinder 143 can basically only move or slide parallel to the outer cylinder 141 in one direction (e.g., in the up and down direction), the inner cylinder 143, the elastic element 142 and the outer cylinder 141 form a single-degree-of-freedom oscillation system.

[0045] Continue as Figure 2 As shown, the upper end of the inner cylinder 143 is fixedly connected to the lower end of the drive component 120. For example, if the drive component 120 is a motor, the upper end of the inner cylinder 143 is fixedly connected to the motor shaft at the lower end of the motor.

[0046] Therefore, when the liftable body 110, driven linearly by the drive component 120, receives an external force, for example, in the vertical direction, this external force can be at least partially transmitted to the drive component 120 and then to the inner cylinder 143. Thus, the inner cylinder 143 can shift relative to the outer cylinder 141 in the vertical direction when the liftable body 110 receives this external force. For example, under a downward external force, the inner cylinder 143 shifts downward and compresses the elastic element 142. After the external force is removed, the elastic element 142 can provide a rebound force to drive the inner cylinder 143 back upward. During the shifting process, the elastic element 142 can also buffer the shift of the inner cylinder 143. For example, when the liftable body 110 is subjected to an abnormal downward external force, the elastic element 142 can buffer the downward shift of the inner cylinder 143; when the liftable body 110 is subjected to an abnormal upward external force, the elastic element 142 can buffer the upward shift of the inner cylinder 143. Thus, the connecting sleeve assembly 140 can buffer the upward or downward external forces received by the liftable body 110.

[0047] Continue as Figure 2As shown, the outer cylinder 141 can be fixed to the base 150, so that the outer cylinder 141 is basically fixed when the liftable body 11 receives an upward or downward external force. In one embodiment, an ear protrusion 1414 is integrally provided on the outer wall of the outer cylinder 141, and the outer cylinder 141 is fixed to the base 150 by the ear protrusion 1414, for example, it is detachably fixed to the base 150. Furthermore, when, for example, the drive member 120 pushes the liftable body 110 upward, the ear protrusion 1414 and the base 150 can also provide support for the drive member 120 (e.g., a motor).

[0048] Continue as Figure 2 As shown, in one embodiment, when the driving member 120 is a motor, the lower end of the driving member has a motor shaft 129 of the motor; correspondingly, the upper end of the inner cylinder 143 has a notch for receiving part of the motor shaft 129, the motor shaft 129 is inserted into the notch, and the inner cylinder 143 is provided with a through hole 1433; the connecting sleeve assembly 140 also includes a bolt 144, the bolt 144 passes through the through hole 1433 of the inner cylinder 143 from the lower end and is threadedly connected to the motor shaft 129 placed in the notch at the upper end, so that the inner cylinder 143 is fixedly positioned relative to the driving member 120.

[0049] Continue as Figure 2 As shown, the connecting sleeve assembly 140 also includes a limiting portion 145 disposed at the lower end of the inner cylinder 143, the limiting portion 145 protruding outward and abutting against the lower end face of the outer cylinder 141. To facilitate the installation of the inner cylinder 143, the limiting portion 145 is separable from the inner cylinder 143, which can be achieved, for example, by a gasket, the outer diameter of which is larger than the inner diameter of the second cylinder wall portion 1412 of the outer cylinder 141.

[0050] The connecting sleeve assembly 140 in the above embodiments can effectively buffer the external force on the exposed liftable main body 110, thereby preventing damage due to excessive internal force, such as preventing damage to the motor, which is the drive component 120, and thus greatly improving the reliability and service life of the human-computer interaction device 10. For example, in a certain scenario, if a user abnormally slaps the liftable main body 110, the force can be transmitted to the elastic element 142 of the connecting sleeve assembly 140 and at least partially absorbed by the elastic element 142. At the same time, the inner cylinder 143 shifts downward, and the liftable main body 110 generates a small vibration.

[0051] Specifically, the elastic element 142 can be selected as a spring. By setting the wire diameter, elastic coefficient K, etc. of the spring, the inner cylinder 143 will not be displaced relative to the outer cylinder 141 when the drive component 120 drives the liftable body 110 to perform an upward or downward movement.

[0052] In another embodiment, a damper (not shown) may be arranged between the outer cylinder 141 and the inner cylinder 143. The damper can attenuate the vibration in the generally vertical direction generated by the elastic element 142 under the action of an external force. For example, after the inner cylinder 143 is displaced, the external force is released, and the elastic element 142 generates vertical vibration. This vibration is usually undesirable to the user and is prone to generating noise. Through the vibration attenuation effect of the damper, this vibration can be reduced and the noise suppressed. Of course, the damper can also form a single-degree-of-freedom oscillation system together with the elastic element 142, etc.

[0053] In one example, the damping material is a damping grease, which at least partially covers the elastic element 142. For example, the damping grease fills the enclosed space surrounded by the flange 1431, the first cylindrical portion 1411, the step 1413, and the inner cylinder 143. By selecting the damping grease, the magnitude of the damping it produces when the inner cylinder 143 undergoes relative displacement can be determined. Therefore, by simultaneously selecting the elastic coefficient K value of the elastic element 142 and the damping magnitude of the damping grease (e.g., the damping value of the damping grease is equal to the critical damping), the fastest possible attenuation rate can be achieved for vibrations in, for example, the single-degree-of-freedom oscillating system described above.

[0054] In another example, the damping element is a piston ring, which is fixed to the inner cylinder 143 and moves with the inner cylinder 143. For example, the piston ring can be fixed on the outer circumferential surface of the flange 1431. By setting the characteristics of the piston ring, the magnitude of the damping it generates when the inner cylinder 143 moves relative to it can be determined. At the same time, by selecting the elastic coefficient K value of the elastic element 142 and the magnitude of the damping generated by the piston ring, the fastest possible attenuation speed of vibration can be achieved.

[0055] In another embodiment, the connecting sleeve assembly 140 further includes a mechanical limiting portion (not shown in the figure), which limits the lowest possible position of the liftable body 110 (e.g., limiting it to a position where the upper surface of the liftable body 110 is approximately flush with the substrate 190) and prevents downward external forces from being transmitted to the connecting sleeve assembly 130 at this lowest position. The motor can be protected by a simple mechanical limiting method, meaning that the damping protection mechanism of the connecting sleeve assembly 140 does not need to operate when the liftable body 110 is in its lowest position; and, through this mechanical limiting, the upper surface of the liftable body 110 can also be prevented from falling below the substrate 190.

[0056] The human-computer interaction device 10 in the above embodiments has a good buffering effect against external forces and is not easily damaged by user misoperation; it can also effectively attenuate the forced vibration caused by external forces, further avoiding unnecessary noise or even damage.

[0057] The above examples primarily illustrate various human-computer interaction devices of the present invention, in-vehicle intelligent interaction systems using these devices, and vehicles using these systems. Although only some embodiments of the present invention have been described, those skilled in the art should understand that the present invention can be implemented in many other forms and integrated together without departing from its spirit and scope. Therefore, the examples and embodiments shown are to be considered illustrative rather than restrictive, and the present invention may encompass various modifications and substitutions without departing from the spirit and scope of the invention as defined in the appended claims.
