[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0034] Please also refer to Figures 1 to 2The multi-stage damping system 100 for a smart chair provided in an embodiment of the present application is now described. The multi-stage damping system 100 for a smart chair comprises a base 10, an armrest 20, and a rotating connector 30 connecting the base 10 and the armrest 20. The base 10 is movably connected to the armrest 20 via the rotating connector 30.

[0035] For details, please refer to Figure 3 The armchair 20 is provided with a side support frame 21 and an elastic buffer mechanism 22. The elastic buffer mechanism 22 includes a back force frame 221 and a shock-absorbing spring 222. The back force frame 221 is connected to the side support frame 21 through the shock-absorbing spring 222.

[0036] It is understood that the side wing support frames 21 include two, one on each side of the armchair 20. The back force-bearing frame 221 is used to directly bear the pressure of the human back. After the back force-bearing frame 221 bears the pressure of the human back, it compresses the shock-absorbing spring 222, which transmits the pressure to the side wing support frames 21. In this way, the elastic buffer mechanism 22 can dynamically play the role of absorbing kinetic energy in the first stage.

[0037] For details, please refer to Figure 3 A movable frame 11 and a translation driving mechanism 12 are provided in the base 10 , and the movable frame 11 is provided on the translation driving mechanism 12 .

[0038] For details, please refer to Figure 4 The rotating connecting member 30 includes a main shaft 31, a pre-tightening rubber ring 32 and a spring 33. The main shaft 31 is fixed on the movable frame 11, and the side wing support frame 21 is connected to the main shaft 31 through the pre-tightening rubber ring 32. One end of the spring 33 is connected to the side wing support frame 21, and the other end is connected to the movable frame 11.

[0039] It is understandable that the pre-tightening rubber ring 32 can provide an initial pre-tightening force F1 for the rotating connector 30 to hinder the rotation of the armchair 20. The pre-tightening rubber ring 32 can be a silicone ring, which is sleeved on the main shaft 31.

[0040] That is, when the vehicle is driven normally, the torsion F provided by the pressure of the human back borne by the back force frame 221 is less than F1, the rotary connector 30 does not rotate relative to the vehicle, and the armchair 20 does not fall over.

[0041] In the event of an emergency braking of the vehicle, the pressure on the human back borne by the back force frame 221 provides a torsional force F>F1, the shock-absorbing spring 222 is first compressed to the upper limit, and then the rotating connector 30 rotates relatively, gradually compressing the mainspring 33, and the backrest 20 tilts backward at a certain angle, triggering the second stage of passive unloading through the rotation of the backrest 20.

[0042] Furthermore, after the emergency braking, the internal force generated by the compressed spring 33 can overcome the initial preload force F1, causing the rotating connector 30 to automatically recover. In a preferred embodiment, the spring 33 is a constant internal force spring, and the internal force of the spring 33 is slightly greater than the initial preload force F1, that is, it can ensure the seat rebounds.

[0043] Specifically, a non-powered pointer 34 is provided at the end of the main shaft 31, and a rotation into position detector 23 is provided on the side support frame 21. The intelligent seat multi-order shock absorption system 100 also includes a microprocessing unit, which is respectively connected to the translation drive mechanism 12 and the rotation into position detector 23. When the non-powered pointer 34 triggers the rotation into position detector 23, the microprocessing unit controls the translation drive mechanism 12 to drive the movable frame 11 to move backward.

[0044] In the event of an accident, after the elastic buffer mechanism 22 has a shock-absorbing effect in the first stage and the rotating connector 30 has a force-relieving effect in the second stage, the back force-bearing skeleton 221 still bears a large pressure from the human back. The main shaft 31 drives the unpowered pointer 34 to rotate until the rotation into position detector 23 is triggered. The microprocessor unit controls the translation drive mechanism 12 to drive the movable frame 11 to move backward, thereby realizing the active collapse effect of the third stage through the translation drive mechanism 12.

[0045] Thus, the initial pressure F exerted by the back of the human body on the chair 20 is star Dynamic equilibrium pressure F after multi-stage shock absorption balance See the relationship diagram for Figure 5 shown.

[0046] The intelligent seat multi-stage shock absorption system 100 provided in the embodiment of the present application adopts a three-stage collaborative buffering mechanism. According to the degree of vibration of the backrest 20, it combines passive and active methods to form a progressive shock absorption protection chain of "spring → rotation → translation", providing constant support pressure for the human back, and significantly improving the safety and comfort of the seat in all vehicle driving scenarios.

[0047] In another embodiment of this application, please refer to Figure 6The translation drive mechanism 12 includes a backward rotation mechanism 121, a forward rotation mechanism 122 and a synchronous toothed belt 123. The backward rotation mechanism 121 includes a backward drive component (not shown), a backward rotating shaft 1212 and a backward gear 1213. The backward drive component is connected to the backward gear 1213 through the backward rotating shaft 1212. The forward rotation mechanism 122 includes a forward drive component (not shown), a forward rotating shaft 1222 and a forward gear 1223. The forward drive component is connected to the forward gear 1223 through the forward rotating shaft 1222. One end of the synchronous toothed belt 123 is wound around the backward gear 1213, and the other end is wound around the forward gear 1223.

[0048] It can be understood that, unlike the translational drive method of conventional seats, this embodiment adopts a single-belt bidirectional drive structure, that is, when the rear drive component is driven, the rear gear 1213 and the forward gear 1223 both rotate counterclockwise, driving the armchair 20 to move backward; when the forward drive component is driven, the rear gear 1213 and the forward gear 1223 both rotate clockwise, driving the armchair 20 to move forward.

[0049] Thus, when the single-belt, bidirectional drive structure described above is applied to the vehicle backrest 20, the translation drive mechanism 12 can resist severe deformation caused by a vehicle collision, including collision-induced extension or compression of the lateral spacing between the forward gear 1223 and the rear shaft 1212. For example, even if the vehicle body deforms severely, causing the lateral spacing to extend, one gear will release the timing belt 123 to the other gear to resist the extension. If the lateral spacing is compressed, the translation drive mechanism 12 can actively move backward, creating space for passengers to escape, thereby improving reliability in the event of an accident.

[0050] In addition, in the event of an accident, at the beginning of the third stage, when the rear drive assembly has not yet responded, the armchair 20 can passively drive the synchronous toothed belt 123 to move backward a certain distance, forming a preliminary passive unloading effect, and then realize the active collapse effect of the third stage after the rear drive assembly is started, thereby further improving safety.

[0051] For further information, please also refer to Figure 6The rear drive assembly includes a rear servo motor (not shown), which directly drives the rear shaft 1212. The forward drive assembly includes a forward servo motor (not shown), a synchronous shaft 1225, a synchronous gear 1226 and a flat transmission belt 1227. The rear servo motor drives the synchronous gear 1226 through the synchronous shaft 1225. The synchronous gear 1226 is engaged with the synchronous toothed belt 123. The flat transmission belt 1227 is simultaneously wrapped around the synchronous shaft 1225 and the forward shaft 1222.

[0052] It is understood that in the event of an accident, the rear servo motor provides active driving power during the rearward movement of the armchair 20, driving the synchronous toothed belt 123 to move backward. That is, when the rear gear 1213 and the forward gear 1223 both rotate counterclockwise, the armchair 20 moves backward. The winding amount of the synchronous toothed belt 123 on the rear gear 1213 increases (the winding radius increases), while the winding amount of the synchronous toothed belt 123 on the forward gear 1223 decreases (the winding radius decreases). In this way, the rearward movement speed of the armchair 20 will become increasingly faster, thereby strengthening the active collapse effect of the third stage and further improving safety.

[0053] However, after the accident, the forward servo motor provides active driving power during the forward movement of the armchair 20, driving the synchronous toothed belt 123 forward. When the rear gear 1213 and the forward gear 1223 both rotate clockwise, the armchair 20 moves forward. The winding amount of the synchronous toothed belt 123 on the rear gear 1213 decreases (the winding radius decreases), while the winding amount of the synchronous toothed belt 123 on the forward gear 1223 increases (the winding radius increases). In theory, the backward movement speed of the armchair 20 will increase. However, because the synchronous gear 1226 is engaged with the synchronous toothed belt 123, the speed synchronization of the synchronous toothed belt 123 and the synchronous gear 1226 is forcibly limited.

[0054] When the linear velocities caused by the two aforementioned situations are mutually exclusive, resistance is generated. However, because the forced synchronization of the synchronous toothed belt 123 takes precedence over the frictional drive of the flat drive belt 1227, the ultimate result is relative motion between the flat drive belt 1227 and the synchronous shaft 1225 or the forward shaft 1222, thereby generating uniform forward motion.

[0055] Thus, the beneficial effects of this embodiment are: when an accident occurs, the backrest 20 forms an accelerated backward movement, which strengthens the active collapse effect of the third stage; after the accident occurs, the backrest 20 forms a uniform forward movement during the reset process, further improving safety and comfort.

[0056] For further information, please also refer to Figure 7A first slot 1228 is provided on the forward gear 1223 , a second slot 1229 is provided on the forward rotating shaft 1222 , the synchronous toothed belt 123 is located in the first slot 1228 , and the flat transmission belt 1227 is located in the second slot 1229 .

[0057] It can be understood that, by providing the first slot 1228 and the second slot 1229 , the synchronous toothed belt 123 and the flat transmission belt 1227 can rotate independently of each other to avoid mutual interference.

[0058] For further information, please also refer to Figure 6 , the radius of the forward gear 1223 is the same as that of the backward gear 1213.

[0059] For further information, please also refer to Figure 3 The translation drive mechanism 12 also includes a support platform 124, a slide rail 125 and a slider 126. The slide rail 125 is arranged on the support platform 124, the slider 126 is fixed on the synchronous toothed belt 123 and is slidably arranged with the slide rail 125, and the movable frame 11 is fixed on the slider 126.

[0060] It is understandable that the support platform 124 can be used to bear the weight of the movable frame 11, and the slide rail 125 can provide guidance and reduce friction, thereby improving movement stability.

[0061] For further information, please also refer to Figure 1 The rotating connector 30 further includes a manual knob 34 , which is located on the outer surface of the armchair 20 and is connected to the unpowered pointer 34 .

[0062] It is understandable that, when necessary, the passenger can also adjust the front and rear position of the armchair 20 through the manual knob 34, thus achieving a combination of manual and automatic.

[0063] For further information, please also refer to Figure 4 A rotation reset detector 24 is also provided on the side wing support frame 21, and the microprocessor unit is connected to the rotation reset detector 24. When the unpowered pointer 34 triggers the rotation reset detector 24, the microprocessor unit controls the translation drive mechanism 12 to drive the movable frame 11 to stop moving forward.

[0064] It can be understood that the accuracy of the reset is improved by sensing whether the reset is in place through the rotation reset detector 24, and the rotation reset detector 24 can also be used to perform zero position calibration.

[0065] See also Figure 8The present application also provides a smart cockpit 200, which includes a central processing unit 201, an on-board sensor 202, a driving assistance system 203 and the smart seat multi-stage shock absorption system 100 as described above.

[0066] Specifically, the vehicle-mounted sensor 202 is connected to the driving assistance system 203, and the driving assistance system 203 and the intelligent seat multi-order shock absorption system 100 are respectively connected to the central processing unit. The vehicle-mounted sensor 202 is used to obtain information about the vehicle's surrounding environment. After the driving assistance system 203 detects an accident, it sends an emergency instruction to the central processing unit. The central processing unit issues an active risk avoidance instruction to the microprocessor unit, and the microprocessor unit controls the translation drive mechanism 12 to drive the movable frame 11 to move backward.

[0067] It is understandable that when the intelligent seat multi-stage shock absorption system 100 is combined with the driving assistance system 203, the driving assistance system 203 can start responding to the active collapse action of the third stage in advance after detecting an accident, so as to reduce delay and improve safety.

[0068] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
