[0023] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0024] The embodiments of the present application are described below in conjunction with Figure 1 and Figure 2 The cushion assembly according to the embodiments of the present application is described.

[0025] The cushion assembly of the embodiments of the present application comprises a cushion bottom plate 1, a cushion skin 2, an elastic body 3, an air bag 4, an inflation device 5, a height sensor 6, a control panel 7 and a controller 8. The cushion skin 2 is connected with the cushion bottom plate 1, and the cushion skin 2 and the cushion bottom plate 1 surround to form a volume-adjustable accommodating cavity. The elastic body 3 and the air bag 4 are arranged in the accommodating cavity. The inflation device 5 is connected with the air bag 4. The height sensor 6 is used for detecting the height of the cushion skin 2. The control panel 7, the inflation device 5 and the height sensor 6 are all electrically connected with the controller 8.

[0026] According to the cushion assembly of the embodiments of the present application, the air bag 4 is arranged in the accommodating cavity surrounded by the cushion bottom plate 1 and the cushion skin 2, and the inflation device 5 can realize the adjustment of the height of the cushion skin 2 by inflating the air bag 4, thereby improving the riding comfort of users of different heights. In addition, the user can adjust to the height value desired to reach through the control panel 7, the controller 8 controls the inflation device 5 to work accordingly, and when the height sensor 6 detects that the height of the cushion skin 2 reaches the set value, the controller 8 controls the inflation device 5 to stop working, thereby realizing the height adjustment of the cushion skin 2, and the height adjustment has a high degree of automation.

[0027] It should be noted that the height of the cushion skin 2 can refer to the average height thereof, or the height of the highest point thereof. The cushion skin 2 is connected with the cushion bottom plate 1 through gun nails, and the cushion skin 2 is made of a material having a certain ductility, so that when the volume of the accommodating cavity changes due to the inflation and deflation of the air bag 4, the cushion skin 2 is always in a tightened state.

[0028] In some embodiments, the cushion assembly further comprises a pressure sensor 9 arranged in the air bag 4 and used for detecting the pressure of the air bag 4, and the pressure sensor 9 is electrically connected with the controller 8.

[0029] When the inflation device 5 works, the controller 8 monitors the pressure of the air bag 4 at all times through the pressure sensor 9, so as to prevent the air bag 4 from being over-inflated or over-deflated, thereby effectively improving the service life of the air bag 4 while ensuring the riding comfort of the passenger.

[0030] For example, the number of air bags 4 is multiple, and the pressure sensor 9 is arranged in one of the air bags 4.

[0031] For example, the number of air bags 4 is multiple, and the pressure sensor 9 is arranged in each air bag 4 one by one, so that the pressure state of each air bag 4 is detected, and the pressure of a single air bag 4 is prevented from being too large or too small, and the timely repair of an abnormal air bag 4 is facilitated.

[0032] In some embodiments, as shown in FIG. 1, the air bag 4 is arranged between the elastic body 3 and the cushion bottom plate 1, and the height sensor 6 is arranged above the elastic body 3 or the air bag 4. Figure 1

[0033] At this time, the elastic body 3 is in close contact with the cushion skin 2, that is, no matter how the volume of the air bag 4 is adjusted, the cushion assembly supports the user through the elastic body 3, and the user's riding comfort is good. In addition, under the blockage of the elastic body 3, external sharp objects are also effectively prevented from directly damaging the air bag 4 through the cushion skin 2, effectively improving the service life and use reliability of the air bag 4. And by arranging the height sensor 6 above the elastic body 3 or the air bag 4, when the air bag 4 is inflated and deflated, the height sensor 6 can move at the same speed as the highest point of the cushion skin 2 in the height direction, and the height detection reliability of the height sensor 6 on the cushion skin 2 is higher.

[0034] For example, the outer contour of the upper surface of the elastic body 3 matches the outer contour of the cushion skin 2, so that the elastic body 3 is in close contact with the cushion skin 2, and the shape of the outer contour of the cushion skin 2 is stable and reliable at any height, and the support effect on the user is good.

[0035] In some embodiments, as shown in FIG. 1, the air bag 4 is arranged on the side of the elastic body 3 away from the cushion bottom plate 1, and the height sensor 6 is arranged above the air bag 4. Figure 2

[0036] That is, the air bag 4 is in direct contact with the cushion skin 2. This arrangement can not only adjust the height of the cushion skin 2, but also take away the heat of the cushion skin 2 through the circulation of inflation and deflation of the air bag 4 when the temperature of the cushion skin 2 is too high, so as to achieve the effect of cooling. And by arranging the height sensor 6 above the air bag 4, when the air bag 4 is inflated and deflated, the height sensor 6 can move at the same speed as the highest point of the cushion skin 2 in the height direction, and the height detection reliability of the height sensor 6 on the cushion skin 2 is higher.

[0037] In some embodiments, the number of air bags 4 is one. This arrangement can not only adjust the height of the cushion skin 2, but also reduce the number of parts of the cushion assembly, simplify the structure, and reduce the cost.

[0038] For example, the inflation device 5 is connected to the air bag 4 through a conduit.

[0039] Alternatively, as shown in FIG. 2, the inflation device 5 is connected to the air bag 4 through a plurality of conduits. Figure 1 and Figure 2 ​​As shown, the number of air bags 4 is multiple and arranged on the same horizontal plane, and the multiple air bags 4 are connected in series and / or in parallel.

[0040] At this time, the multiple air bags 4 are arranged at different positions on the same horizontal plane, and the height adjustment effect of each position of the seat skin 2 is better when the air bags 4 are inflated or deflated, and the user experience is better.

[0041] Optionally, the multiple air bags 4 are connected in series, one of which is connected to the inflation device 5 through a conduit, or the multiple air bags 4 are connected in parallel, and the multiple air bags 4 are connected to the inflation device 5 through a multi-way pipe, or the multiple air bags 4 are connected in series and parallel, to ensure that the inflation and deflation consistency of each air bag 4 is higher.

[0042] It should be noted that when the air bag 4 is multiple, the multiple air bags 4 are limited to different positions on the same horizontal plane by a limiting mechanism to ensure that they do not horizontally displace and affect the outer contour shape of the seat assembly. Alternatively, the air bag 4 can also be limited to different positions on the same horizontal plane by being bonded to the seat bottom plate 1 and / or the elastic body 3.

[0043] In some embodiments, the air bag 4 is a rubber or silicone piece.

[0044] Thus, the air bag 4 has sufficient flexibility and ductility, and when it is in direct contact with the seat skin 2, it can provide better flexible support to the user through the seat skin 2, and the user's ride comfort is higher.

[0045] In some embodiments, the control panel 7 includes a touch screen or control buttons. That is, the user can adjust the height of the seat skin 2 through the touch screen, and at this time the control panel 7 can be integrated on the central control screen of the electric vehicle to effectively reduce the cost of the seat assembly. The user can also adjust the height of the seat skin 2 by turning the control buttons, and the height adjustment reliability is high.

[0046] For example, the control panel 7 is arranged at the handlebar of the electric vehicle, so that the operation of the control panel 7 is simple and convenient.

[0047] In some embodiments, the elastic body 3 includes any one of foam, sponge, memory foam, latex, and fiber cotton.

[0048] At this time, the elastic body 3 can be compressed when it is pressed to provide good flexible support to the user and improve the user's ride comfort.

[0049] For example, the elastic body 3 is a sponge to effectively reduce the manufacturing cost of the seat assembly. For another example, the elastic body 3 is memory foam or latex to ensure that it has good air permeability and better flexible support to provide better comfortable experience to the user.

[0050] In some embodiments, the inflator 5 comprises a gas pump.

[0051] The gas pump can efficiently realize the inflation and deflation of the air bag 4, and can also perform emergency inflation when the tire of the electric vehicle is flat, so as to effectively avoid the problem that the electric vehicle cannot be ridden due to tire flatness in an open area, and the user's use satisfaction is higher.

[0052] For example, the gas pump is detachably installed at a seat bucket position of the electric vehicle.

[0053] The scooter according to the embodiment of the present application comprises the seat cushion assembly according to any of the above embodiments.
