[0038] Embodiment 2

[0040] More specifically, the seat base 200 also includes a telescopic motor 251 disposed between the rotating base 240 and the movable plate 250 to drive horizontal movement of the movable plate 250; a front-rear motor 231 disposed between the base 220 and the load-bearing seat 230 to drive fore-aft movement of the load-bearing seat 230; and a rotary motor 241 disposed between the load-bearing seat 230 and the rotating base 240 to drive horizontal rotation of the rotating base 240. The telescopic motor 251, the front-rear motor 231, and the rotary motor 241 are electrically connected to the seat base circuit board 140. The arrangement of the telescopic motor 251, the front-rear motor 231, and the rotary motor 241 facilitates control of the seat base 200 by the main controller 140. In this embodiment, the drive circuitry on the seat base circuit board 140 that drives the telescopic motor 251, the front-rear motor 231, and the rotary motor 241 is conventional and readily apparent to those skilled in the art, and will not be described in detail here.

[0041] More specifically, the seat base 200 also includes two telescopic sensors 252, both electrically connected to the seat base circuit board 140, for detecting movement of the movable plate 250 to its retracted and extended limits, respectively; two front and rear sensors 232, both electrically connected to the seat base circuit board 140, for detecting movement of the load-bearing base 230 to its front and rear limit positions, respectively; and two rotation sensors 242, both electrically connected to the seat base circuit board 140, for detecting rotation of the rotating base 240 to its stowed and extended limits, respectively. The provision of the telescopic sensors 252, the front and rear sensors 232, and the rotation sensor 242 improves the precision of the main controller 140's control of the seat base 200.

[0042] More specifically, the auxiliary lifting mechanism 500 includes a lifting rod 510 with an upward movable end, and an elastic support member 520 provided on an upper end surface of the movable end.

[0043] More specifically, if Figure 4 As shown, the lifting rod 510 is an electric push rod; the elastic support member 520 includes a sliding sleeve 521 mounted on the outer periphery of the upper end of the movable end, a spring 522 whose lower end abuts the movable end and whose upper end abuts the sliding sleeve 521, and an upper resistor 523 and a lower resistor 524 arranged in the inner cavity of the spring 522 and whose ends are pressed and connected to each other; the movable end is provided with a mounting groove 511 for mounting the spring 522; the upper resistor 523 and the lower resistor 524 are connected in series and then connected to the control board of the electric push rod, and the operation of the electric push rod is controlled by changes in resistance value.

[0044] When the movable plate 250 is descending, the spring 522 is compressed under force, the resistance between the upper resistance sheet 523 and the lower resistance sheet 524 becomes smaller, and is smaller than the set low value, the electric push rod starts to work, and the ascending speed of the electric push rod is greater than the ascending speed of the movable plate 250, the force of the spring 522 becomes smaller, and gradually returns to the original length; the resistance between the upper resistance sheet 523 and the lower resistance sheet 524 becomes greater, and is greater than the set high value, the electric push rod stops working; the spring 522 is compressed again, and so on, so that the spring 522 bears a certain range of pressure, thereby playing a boosting role on the movable plate 250 and the seat cushion body 300.

[0045] When the movable plate 250 needs to ascend, the working principle is opposite to the above-mentioned working principle, that is, when the movable plate 250 ascends, the spring 522 gradually returns to the original length, when the resistance between the upper resistance sheet 523 and the lower resistance sheet 524 becomes greater, and is greater than the set high value, the electric push rod starts to work, and the ascending speed of the electric push rod is greater than the ascending speed of the movable plate 250; the spring 522 is compressed under force, the resistance between the upper resistance sheet 523 and the lower resistance sheet 524 becomes smaller, and is smaller than the set low value, the electric push rod stops working; the force of the spring 522 becomes smaller, and gradually returns to the original length, the spring 522 gradually returns to the original length again, and so on, so that the spring 522 bears a certain range of pressure, thereby playing a boosting role on the movable plate 250 and the seat cushion body 300. Further, the support seat is also provided with a battery connected with the control board of the electric push rod. In order to adapt to people with different weights, springs with different thicknesses can be selected, or the adjusting knob connected with the control board of the electric push rod can be adjusted, for example, the set low value and the set high value can be kept at a low value with a small difference, in this case, the spring is in a state of high compression amount, and can provide high support force, and the specific value can be calculated according to the spring size and the compression amount. Since the movable plate moves horizontally and ascends and descends at the same time, in the initial state of horizontal movement, the movable plate extends a small distance, at this time, the movable plate has not moved to the outside of the carriage, the auxiliary lifting mechanism has not contacted the movable plate, and does not play a supporting role. The compression amount of the spring as a buffer and adjustment reduces the synchronous control requirement between the support seat and the seat cushion body; at the same time, the support force is adjusted, and two goals are achieved at one time. When the seat cushion body is completely supported by the support seat, the electric push rod needs to be completely retracted and separated from the bottom of the movable plate.

[0046] In other embodiments, the auxiliary lifting mechanism can also act on the bottom of the seat cushion body, and this structure is easier to realize the separation operation of the movable plate and the seat cushion body.

[0047] In other embodiments, the auxiliary lifting mechanism can also be a pneumatic support rod.

[0048] In other embodiments, the support seat and the seat cushion body also adopt the structure of the electric plug and the electric socket, realizing the connection of the power lines and the signal lines between the circuit boards of the two, so that the online driving operation of the support seat can be realized through the control panel of the seat cushion body (placed at the position of the armrest, which is convenient for the user to operate).

[0049] In other embodiments, the number of the auxiliary lifting mechanisms 500 in the present embodiment is two, which are distributed at the two opposite sides of the support seat 400. Of course, in other embodiments, the number can be other numbers, but it is necessary to ensure that all the auxiliary lifting mechanisms 500 are synchronous lifting, and the lifting amplitude is also the same.

[0050] More specifically, the bottom of the support seat 400 is provided with four casters 410. Among them, the two front casters are steerable casters.

[0051] The power-assisted seat described above solves the problem of integrated control by adopting the intelligent seat control system S with the above structure. The user sits on the seat cushion body 300 and can control the seat cushion body 300 and the seat base 200 through the control panel 150. In addition, the auxiliary lifting mechanism 500 described above can provide a certain supporting force to the seat cushion body 300 after the movable plate 250 transfers the seat cushion body 300 to the outside of the vehicle and is placed in the support seat, thereby reducing the load of the movable plate 250, i.e. reducing the supporting force of the load-bearing seat 230 and the rotating bottom plate 240, and reducing the wear of the related parts.

[0052] The above only further illustrates the technical content of the present application by way of examples, so as to make it easier for the reader to understand, but does not represent that the embodiments of the present application are limited to this. Any technical extension or re-creation made according to the present application is also protected by the present application. The protection scope of the present application is subject to the claims.
