In one specific embodiment, the decorative pad 11 is a flexible pad.

[0046] The support device 1 of the embodiment is connected to the vehicle seat 2 through the decorative pad 11, and supports the body part of the user through the inflatable bag assembly 12. When the inflation mechanism 10 is in the deflated state, the decorative pad 11 will be able to be integrated with the vehicle seat 2 as a decoration, without affecting the daily riding comfort of the user and being more aesthetic.

[0047] In some embodiments, referring to Figure 4 , a connecting hole 11a is formed on the decorative pad 11, the connecting hole 11a penetrates the decorative pad 11 in the thickness direction of the decorative pad 11, and the connecting hole 11a is used for the structure of the vehicle seat 2 to pass through.

[0048] As an example, referring to Figure 1 and Figure 4 , the vehicle seat 2 can include a seat body 21 and a headrest 22, the top side of the seat body 21 has a plug-in hole 21a, and the bottom side of the headrest 22 has a connecting column 221, the connecting hole 11a can be used for the connecting column 221 to pass through, in the actual assembly process, the connecting column 221 can pass through the connecting hole 11a and be inserted into the plug-in hole 21a, so as to realize the connection of the decorative pad 11 and the vehicle seat 2. One advantage of this connection mode is that it can improve the versatility of the support device 1, and another advantage is that it is convenient for the user to install or disassemble by himself / herself. Of course, those skilled in the art can understand that the connecting hole 11a can also be used for any suitable structure on the vehicle seat 2 to be inserted.

[0049] In some embodiments, a plurality of different types of connection holes 11a are formed on the decorative cushion 11, and are respectively used for passing through different types of structural members of the vehicle seat 2, for example, one type of connection hole 11a is used for passing through the connection column 221 at the bottom side of the headrest 22 described above, and another type of connection hole 11a is used for passing through the armrest of the vehicle seat 2. In this way, the versatility and functional expansion of the supporting device 1 are improved. In the present embodiment, the shapes and / or sizes of the different types of connection holes 11a can be the same or different, and no limitation is made in this regard.

[0050] In some embodiments, at least one connection hole 11a group can be formed on the decorative cushion 11, each connection hole 11a group including a plurality of connection holes 11a, and the plurality of connection holes 11a in the connection hole 11a group being used for passing through the structural members of the vehicle seat 2 alternatively, in other words, the user can pass the structural members of the vehicle seat 2 through one of the connection holes 11a in the connection hole 11a group according to the actual use requirement, in this way, the relative position between the decorative cushion 11 and the vehicle seat 2 can be adjusted.

[0051] In some embodiments, referring to Figure 4 , the decorative cushion 11 includes a sheet-shaped body 111 and a connecting ear 112, the connecting ear 112 being connected to one end of the sheet-shaped body 111, the connection hole 11a being formed at least on the connecting ear 112, and the inflation bag assembly 12 being arranged on the sheet-shaped body 111. In this way, the aesthetic appearance of the supporting device 1 can be further improved.

[0052] In the present embodiment, the number of connecting ears 112 can be one or multiple, and the multiple connecting ears 112 can be connected to the same section of the sheet-shaped body 111 or different ends of the sheet-shaped body 111. In the case where the number of connection holes 11a is multiple, the multiple connection holes 11a can all be formed on the connecting ear 112, in other words, no connection hole 11a is formed on the sheet-shaped body 111, or a part of the multiple connection holes 11a are formed on the connecting ear 112 and the other part are formed on the sheet-shaped body 111.

[0053] In some embodiments, the decorative cushion 11 can be formed with a hollow portion (not shown in the figure), and the inflation bag assembly 12 can be embedded in the hollow portion, in this way, the inflation bag assembly 12 can be better hidden in the case where the inflation mechanism 10 is in the contracted state, the aesthetic appearance is improved, and the feeling of foreign matter felt by the user when leaning against the decorative cushion 11 is reduced as much as possible.

[0054] In some embodiments, the supporting device 1 includes a power take-off connector 14, and the power take-off connector 14 is electrically connected with the pumping member 13. In this way, the supporting device 1 can take power from the vehicle, and the operation of replacing the battery and / or charging is saved, and the use convenience is further improved.

[0055] As an example, the power supply connector 14 can be a USB connector, and in actual use, the power supply connector 14 can be connected to the power supply interface 21b of the vehicle.

[0056] Of course, in some other embodiments, the pumping member 13 can also be powered by a battery, so as to improve the versatility of the support device 1 (some vehicles can not be provided with the power supply interface 21b or the power supply interface 21b is far away from the vehicle seat 2), and the battery can be a primary battery (such as a dry battery) or a secondary battery (such as a lithium battery), which is not limited.

[0057] In some embodiments, the support device 1 further comprises a controller (not shown in the figure) configured to control the pumping member 13 to perform the filling action and the discharging action at a set frequency. The filling action specifically refers to pumping the filling material into the inflation mechanism 10 by the pumping member 13, and the discharging action specifically refers to discharging the filling material in the inflation mechanism 10 by the pumping member 13.

[0058] As an example, the controller is configured to control the pumping member 13 to cyclically perform the filling action and the discharging action at a set frequency, so that the user's body part can be massaged by the cyclic filling and discharging of the inflation mechanism 10, thereby improving the user's use comfort. The advantage of using the cyclic filling and discharging of the filling material to realize the massage function is that it can not need to additionally provide a separate massage structure, thereby reducing the manufacturing cost of the support device 1, and further reducing the foreign body sensation when the inflation mechanism 10 is in the contracted state.

[0059] In the present embodiment, the controller can be pre-set with multiple massage modes for the user to select, or the user can be allowed to set the massage mode by himself / herself.

[0060] As another example, the controller is configured to control the pumping member 13 to perform a single filling action and a single discharging action at a set frequency, so as to achieve the effect of timed filling and discharging of the filling material.

[0061] The controller can be communicatively connected with the main controller of the vehicle and / or the mobile terminal of the user by means of wireless communication, so as to receive the control signal, and / or the support device 1 can comprise a control switch electrically connected with the controller, and the control switch can be arranged on the decorative pad 11.

[0062] In some embodiments, the inflation bag assembly 12 can comprise multiple inflation bags 121 independent of each other, and the independent of each other means that the multiple inflation bags 121 are not communicated with each other. The pumping member 13 is respectively communicated with the multiple inflation bags 121, and the controller can be further configured to control the pumping member 13 to selectively pump the filling material into a part of the inflation bags 121, so as to realize more massage modes.

[0063] In some embodiments, as a supplement or alternative, the inflation bag assembly 12 can include the inflation bag 121 and massage claws, which can be arranged in the inflation bag 121 and / or arranged on the side surface of the inflation bag 121 away from the decorative pad 11. The massage claws can be arranged to imitate the action of a human hand to massage, and the specific arrangement of the massage claws can refer to the related technology in the art, which will not be described here.

[0064] In some embodiments, referring to Figure 2 , Figure 4 and Figure 5 , the inflation bag assembly 12 includes the inflation bag 121 connected to the decorative pad 11 and the coating layer 122 covering at least the side surface of the inflation bag 121 away from the decorative pad 11. It can be understood that in order to realize the filling and discharging of the filling material, the inflation bag 121 needs to be made of a material with good sealing performance, such as a high polymer material, which is often not aesthetically pleasing and / or skin-friendly. In the present embodiment, the coating layer 122 is arranged on the outer surface of the inflation bag 121, so that the appearance and / or skin-friendliness of the supporting device 1 can be improved.

[0065] As an example, the coating layer 122 can be made of the same material as the decorative pad 11. It can be understood that the inflation bag assembly 12 can include a plurality of inflation bags 121 independent of each other, in which case one coating layer 122 can be used to cover a plurality of inflation bags 121 at the same time, or a plurality of independent coating layers 122 can be used to cover a plurality of inflation bags 121 respectively. In some embodiments, there can be some inflation bags 121 whose side surface away from the decorative pad 11 is covered by other inflation bags 121, in which case only the inflation bag 121 on the outermost side (farthest from the decorative pad 11) can have its side surface away from the decorative pad 11 covered by the coating layer 122.

[0066] In some embodiments, the inflation bag assembly 12 further includes at least one heating element, which can be arranged on the side of the coating layer 122 facing the inflation bag 121, and / or arranged on the side of the coating layer 122 away from the inflation bag 121, and / or embedded in the coating layer 122. In this way, the supporting device 1 also has a heating function, further improving the user's comfort.

[0067] In the present embodiment, the heating element can be an electric heating sheet or an electric heating wire, which can be electrically connected to the power take-off connector 14 in the above-mentioned embodiments in which the supporting device 1 includes the power take-off connector 14.
