[0035] Figure 1 Shown is a partial structural schematic diagram of an embodiment of the electric seat 1 of the present application. Figure 2 Shown Figure 1 A partial enlarged view of point A of the electric seat 1 is shown. Figure 3 Shown Figure 1 The exploded view of the electric seat 1 is shown. Figures 1 to 3 As shown, the electric seat 1 includes a seat body 10, a first adjustment switch 20, a second adjustment switch 30, a recliner assembly 40 and a seat controller 50. The seat body 10 includes a seat back 101 and a seat cushion ( Figure 1 (not shown in the figure). The seat back is provided above the seat cushion. The first adjustment switch 20 is provided on the seat body 10, and is used for the user to input a first adjustment instruction. The first adjustment switch 20 is provided on the seat cushion of the seat body 10 or on the seat back of the seat body 10, which is not limited in the present application. The second adjustment switch 30 is provided on the seat body 10, and is used for the user to input a second adjustment instruction. The second adjustment switch 30 is provided on the seat cushion of the seat body 10 or on the seat back of the seat body 10, which is not limited in the present application.

[0036] The recliner assembly 40 is provided on the seat body 10 and is located at the connection between the seat back 101 and the seat cushion. The recliner assembly 40 is provided between the seat back 101 and the seat cushion and is used to connect the seat back 101 and the seat cushion. In this embodiment, the seat back 101 rotates relative to the seat cushion via the recliner assembly 40. Figures 1 to 3 In the illustrated embodiment, the recliner assembly 40 includes a recliner motor 401 and a recliner assembly 402 connected to the recliner motor 401. The recliner assembly 402 is connected to the seat back 101 and the seat cushion. The recliner assembly 402 is in driving connection with the recliner motor 401 and is movably connected to the connection between the seat back 101 and the seat cushion.

[0037] The seat controller 50 is connected to the first adjustment switch 20, the second adjustment switch 30, and the recliner motor 401. The seat controller 50 is used to control and drive the recliner motor 401 to rotate at a first speed according to a first adjustment instruction from the first adjustment switch 20, and to drive the seat back 101 to rotate at a first speed relative to the seat cushion via the recliner assembly 402. The seat controller 50 is also used to control and drive the recliner motor 401 to rotate at a second speed according to a second adjustment instruction from the second adjustment switch 30, and to drive the seat back 101 to rotate at a second speed relative to the seat cushion via the recliner assembly 402. The rotation speed of the first speed is faster than the rotation speed of the second speed. The rotation speed of the second speed is slower than the rotation speed of the first speed.

[0038] In this embodiment, the power seat 1 may be a second-row power seat in a vehicle. The first adjustment switch 20 may be a fold-flat switch, allowing the user to input a forward fold-flat command. The second adjustment switch 30 may be a comfort adjustment switch, allowing the user to input a slow, comfortable adjustment command. In some embodiments, if the user wishes to fold the seat back 101 forward, the fold-flat switch is operated to input a forward fold-flat command. In response to the forward fold-flat command, the seat controller 50 controls and drives the recliner motor 401 at a first speed, and drives the seat back 101 relative to the seat cushion at a first speed via the recliner assembly 402. This first speed is the forward fold-flat speed, which is relatively fast. In some embodiments, if the user wishes to slowly adjust the seat back 101, the comfort adjustment switch is operated to input a slow, comfortable adjustment command. In response to the slow, comfortable adjustment command, the seat controller 50 controls and drives the recliner motor 401 at a second speed, and drives the seat back 101 relative to the seat cushion at a second speed via the recliner assembly 402. This second speed is the slow adjustment speed, which is relatively slow.

[0039] In the above scheme, a first adjustment switch 20 and a second adjustment switch 30 are provided to allow the user to input different first and second adjustment instructions. The seat controller 50 is provided to control and drive the recliner motor 401 to rotate at the first speed or the second speed according to the different first and second adjustment instructions, and the recliner assembly 402 drives the seat back 101 to rotate relative to the seat cushion at the first speed or the second speed. This meets the needs of users, improves user comfort and increases the usable space of the luggage compartment. To improve customer convenience, a first adjustment switch 20 (first switch button) and a second adjustment switch 30 (second switch button) are provided on the seat body 10 to enable the seat back to achieve comfort adjustment and one-touch reclining function. The comfort adjustment of the seat back 101 requires a slower second speed rotation to facilitate passengers to find a suitable seating position. The one-touch reclining function requires a faster first speed to reduce passengers' waiting time. Furthermore, different adjustment instructions can be input according to different usage scenarios, and then different speed rotations can be adjusted accordingly according to different adjustment instructions, so that the electric seat rotates at different speeds, solving the problem of poor customer experience caused by the constant adjustment speed of the electric seat. In this way, the purpose of speed regulation is achieved, the product experience and competitiveness are improved, and a new experience is brought to customers, with a wider range of applications.

[0040] exist Figures 1 to 3 In the illustrated embodiment, the recliner assembly 402 includes a recliner body 403 and a first connecting plate 404 and a second connecting plate 405 connected to the recliner body 403. The first connecting plate 404 is configured to connect to the seat back 101, and the second connecting plate 405 is configured to connect to the seat cushion. The recliner motor 401 includes a motor body 406 and a rotating shaft 407 connected to the motor body 406. The rotating shaft 407 is connected to the recliner body 403. The motor body 406 drives the rotating shaft 407 to rotate about the axis of the rotating shaft 407, thereby driving the recliner body 403 to rotate about the axis of the rotating shaft 407, thereby driving the seat back 101 to rotate relative to the seat cushion. This arrangement simplifies adjustment by controlling the motor body 406 to drive the rotating shaft 407, thereby driving the recliner body 403 to rotate, thereby driving the seat back 101 to rotate relative to the seat cushion.

[0041] exist Figures 1 to 3In the illustrated embodiment, the recliner motor 401 includes a pair of motor bodies 406, which are disposed at both ends of a rotating shaft 407. The recliner assembly 40 includes a pair of recliner assemblies 402, which are disposed at both ends of the rotating shaft 407 and are located outside the pair of motor bodies 406. The pair of motor bodies 406 are transmission-connected to the pair of recliner assemblies 402 via the same rotating shaft 407. In this embodiment, the two ends of the rotating shaft 407 are respectively connected to the motor body 406, the first connecting plate 404, the recliner body 403, and the second connecting plate 405. In this way, the pair of motor bodies 406 and the pair of recliner assemblies 402 are driven and connected via the same rotating shaft 407, which simplifies the structure while satisfying the driving force.

[0042] exist Figures 1 to 3 In the embodiment shown, the first connecting plate 404 and the second connecting plate 405 are located on both sides of the recliner body 403 in the axial direction of the rotating shaft 407, and the first connecting plate 404 is arranged closer to the motor body 406 relative to the second connecting plate 405. This arrangement makes the layout more compact. Figures 1 to 3 In the illustrated embodiment, one end of a first connecting plate 404 is connected to the seat back 101, and the other end of the first connecting plate 404 is connected to the recliner body 403. One end of a second connecting plate 405 is connected to the recliner body 403, and the other end of the second connecting plate 405 is connected to the seat cushion. This arrangement makes the layout more compact.

[0043] In some embodiments, if a user wishes to fold the seat back 101 forward, the user operates a folding switch to input a forward folding command. Based on the forward folding command, the seat controller 50 controls and drives the motor body 406 to rotate at a first speed, driving the rotating shaft 407 to rotate at a first speed about the axis of the rotating shaft 407, thereby driving the recliner body 403 to rotate about the axis of the rotating shaft 407, and driving the seat back 101 to rotate at a first speed relative to the seat cushion. This enables the seat back 101 of the electric seat 1 to achieve a one-touch folding function. The one-touch folding function requires a relatively fast first speed to reduce passenger waiting time. In some embodiments, if a user wishes to slowly adjust the seat back 101, the user operates a comfort adjustment switch to input a slow, comfort adjustment command. In response to the slow comfort adjustment instruction, the seat controller 50 controls and drives the motor body 406 to rotate at the second speed, thereby driving the rotating shaft 407 to rotate at the second speed about the axial direction of the rotating shaft 407. This in turn drives the recliner body 403 to rotate about the axial direction of the rotating shaft 407, and drives the seat back 101 to rotate relative to the seat cushion at the second speed. In this way, the seat back 101 of the power seat 1 achieves the comfort adjustment function. The comfort adjustment of the seat back 101 requires the relatively slow second speed rotation to facilitate the passenger to find a suitable seating position.

[0044] During the adjustment process, when the seat back 101 is rotated to a large angle relative to the seat cushion, the seat back 101 may be unable to be lifted when there is a load. Therefore, in the present application, the electric seat 1 also includes a power assist mechanism 60, which is used to assist the seat back 101 to rotate to a large angle relative to the seat cushion and to be lifted normally when there is a load.

[0045] exist Figures 1 to 3 In the illustrated embodiment, the power-assisting mechanism 60 is located between the motor body 406 and the recliner assembly 402 in the axial direction of the rotating shaft 407. A first baffle 408 is provided at one end of the first connecting plate 404 connected to the recliner body 403, and the first baffle 408 is disposed toward a side of the motor body 406. A second baffle 409 is provided at one end of the second connecting plate 405 connected to the recliner body 403, and the second baffle 409 is disposed toward a side of the motor body 406. The power-assisting mechanism 60 includes a power-assisting coil spring 601 and an internal connection member 602 connected to the power-assisting coil spring 601. The power-assisting coil spring 601 includes a first end 603 and a second end 604, the first end 603 being connected to the internal connection member 602, and the second end 604 being located between the first baffle 408 and the second baffle 409 in the radial direction of the rotating shaft 407. Internal member 602 is fixed to rotating shaft 407. When motor body 406 drives rotating shaft 407 axially, it also drives internal member 602 axially about rotating shaft 407, causing first end 603 to rotate relative to second end 604 axially about rotating shaft 407. In this application, assist coil spring 601, internal member 602, first baffle 408, and second baffle 409 collectively constitute the assistive adjustment mechanism for seat back 101. In the case of a power seat 1 with different speed adjustment functions, the addition of an assistive adjustment mechanism including assist coil spring 601 can provide assistance. This solves the problem of seat back 101 being unable to lift when the seat back 101 rotates at a large angle relative to the seat cushion and is loaded. This allows for wide-angle adjustment of the double seat backrest, ensuring that the backrest can adjust forward normally under load, thereby improving the user experience and competitiveness of the product.

[0046] exist Figure 3 In the embodiment shown, the first end 603 is located on the inner side of the assist coil spring 601, and the second end 604 is located on the outer side of the assist coil spring 601. The second end 604 is extended downward along the radial direction of the rotating shaft 407 from the peripheral side of the assist coil spring 601. This facilitates overlapping contact with the first baffle 408 and the second baffle 409, and provides better stability. During the adjustment process, when the angle of the seat back 101 relative to the seat cushion is greater than 90°, the second end 604 contacts the second baffle 409. During the adjustment process, when the angle of the seat back 101 relative to the seat cushion is 90°, the second end 604 contacts the first baffle 408. Figure 3In the illustrated embodiment, the internal connecting member 602 is provided with an internal connecting groove 605 extending axially along the rotation axis 407. The first end 603 is snap-fitted into the internal connecting groove 605. This arrangement facilitates assembly and a simple structure, making replacement or maintenance easier.

[0047] exist Figures 1 to 3 In the illustrated embodiment, when the seat back 101 is rotated rearwardly by a large angle relative to the seat cushion and is loaded with multiple people, the internal connection member 602 drives the first end 603 of the assist coil spring 601 to rotate inwardly of the assist coil spring 601, thereby contacting the internal connection member 602 and the second stopper 409. When the seat back 101 is rotated forward, the assist coil spring 601 of the assist mechanism 60 utilizes its own spring force to generate a torque in the same direction as the torque of the motor body 406, thereby resolving the problem of the seat back 101 being unable to lift under load. When the seat back 101 rotates to a vertical position (the seat back 101 is 90° toward the seat cushion), the assist coil spring 601 separates from the second baffle 409 and contacts the first baffle 408. This ensures that when the seat back 101 is fully folded forward and lifted up, the assist coil spring 601 of the assist mechanism 60 will not generate a torque in the opposite direction to the torque of the motor body 406, thereby avoiding additional load on the motor body 406 and affecting the functional durability of the motor body 406.

[0048] exist Figures 1 to 3In the illustrated embodiment, the power seat 1 further includes a wiring harness assembly 70, through which the seat controller 50 is electrically connected to the first adjustment switch 20, the second adjustment switch 30, and the motor body 406. The wiring harness assembly 70 includes a first wiring harness 701, a second wiring harness 702, and a third wiring harness 703. In this embodiment, the seat controller 50 is electrically connected to the first adjustment switch 20 via the first wiring harness 701 and to the motor body 406 via the third wiring harness 703. The seat controller 50 receives a first adjustment signal from the first adjustment switch 20 via the first wiring harness 701 and transmits the corresponding first adjustment command to the motor body 406 via the third wiring harness 703. This generates a first driving force for the motor body 406, driving the rotating shaft 407 to rotate at a first speed, thereby driving the recliner body 403 to rotate at a first speed about the axial direction of the rotating shaft 407, thereby driving the seat back 101 to rotate relative to the seat cushion at the first speed. In this embodiment, the seat controller 50 is electrically connected to the second adjustment switch 30 via a second wiring harness 702 and to the motor body 406 via a third wiring harness 703. The seat controller 50 receives the second adjustment signal from the second adjustment switch 30 via the second wiring harness 702 and transmits the relevant second adjustment command to the motor body 406 via the third wiring harness 703, thereby generating a second driving force for the motor body 406 to drive the rotation shaft 407 at a second speed. This in turn drives the recliner body 403 to rotate about the axis of the rotation shaft 407 at a second speed, thereby driving the seat back 101 to rotate relative to the seat cushion at the second speed. This configuration allows different adjustment commands to be input according to different usage scenarios. The power seat can then be adjusted to different rotation speeds based on the different adjustment commands, thus enabling the power seat to rotate at different speeds. This solves the problem of a poor customer experience caused by a constant adjustment speed for power seats. This achieves the purpose of speed regulation, enhances product experience and competitiveness, and provides customers with a new experience, broadening its applicability.

[0049] In some embodiments, the seat controller 50 also has a speed control function. In this embodiment, the seat controller 50 includes a controller body 501 and a regulator 502 connected to the controller body 501. The controller body 501 is connected to the motor body 406 via the regulator 502. The controller body 501 controls the motor body 406 by controlling the regulator 502. In this embodiment, the regulator 502 is a pulse width modulation (PWM) regulator. In this embodiment, the wiring harness assembly 70 also includes a fourth wiring harness 704, connecting the controller body 501 to the regulator 502 via the fourth wiring harness 704. The PWM regulator outputs a PWM signal. The controller body 501 adjusts the duty cycle of the PWM signal to output different voltage signals, thereby controlling the motor body 406 to rotate at different speeds. The seat controller 50 has a PWM speed control function. Different scenarios can be set using a software algorithm to control the motor body 406 to rotate at different speeds. This achieves the purpose of speed control, enhances the product experience and competitiveness, and provides customers with a new experience and a wider range of applications.

[0050] Figures 1 to 3 In the embodiment shown, the electric seat 1 is adjusted by hardware operation of the first adjustment switch 20 and the second adjustment switch 30. In addition, in the present application, the electric seat 1 can also be adjusted in other ways.
