[0042] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0043] Reference below Figure 1-Figure 12A neck support assembly 10 for a vehicle according to an embodiment of the present application is described, wherein the neck support assembly 10 includes a neck support body 11, a connecting strap 12 and an air release device 13. The neck support body 11 is located at a seat 20 of the vehicle, a first accommodating cavity 111 is formed inside the neck support body 11, one end of the connecting strap 12 is connected to the neck support body 11, a connecting channel 121 communicating with the first accommodating cavity 111 is formed inside the connecting strap 12, the air release device 13 is disposed at the seat 20 and connected to the other end of the connecting strap 12, the air release device 13 is suitable for closing the connecting channel 121, wherein, when a collision occurs with the vehicle, the air release device 13 is suitable for opening the connecting channel 121 to discharge the gas in the first accommodating cavity 111 to the outside through the connecting channel 121.

[0044] At present, in order to improve the driving comfort of drivers and passengers, supports are usually provided on the top of the vehicle seat backrests. When the seats are laid down so that the occupants can lie flat or recline, the supports can provide good support for the neck. However, in case of rear-end collision, the occupants' heads swing backwards rapidly under the influence of inertia, and the existing supports cannot shrink quickly, resulting in greater damage to the cervical spine and the risk of injury or disability.

[0045] like Figure 1 As shown, specifically, the neck support assembly 10 includes a neck support body 11 and a connecting belt 12. The neck support body 11 can be located at the seat 20 of the vehicle, and the specific position can be the top of the backrest of the vehicle seat 20. A support surface is formed on the side of the neck support body 11 away from the seat 20, and the support surface can be used to support the user's cervical spine, thereby ensuring that the neck support body 11 can effectively support the cervical spine of the driver and passenger and improve the user's driving comfort. The shape of the neck support body 11 can be set according to the user's usage requirements, such as streamlined, etc., which is not limited here.

[0046] A first accommodating cavity 111 may be formed inside the collar body 11. It can be understood that the collar body 11 may be constructed as an airbag structure. Fig.11 and Fig.12As shown, the first accommodating chamber 111 can be connected to the inflation valve 113 and the deflation valve 114 through the air pipe 112, and the inflation valve 113 and the deflation valve 114 can be connected to the valve body controller 116, and the valve body controller 116 is electrically connected to the control unit 102 of the vehicle. The inflation valve 113 can control the communication between the air pump 115 and the air pipe 112. When the user controls the neck support body 11 to inflate, at this time, the inflation valve 113 is opened, the deflation valve 114 is closed, the air pump 115 works, and the gas flows into the first accommodating chamber 111 through the air pipe 112, thereby completing the inflation of the neck support body 11. When the user controls the neck support body 11 to deflate, at this time, the inflation valve 113 is closed, the deflation valve 114 is opened, the air pump 115 does not work, and the gas in the neck support body 11 flows out through the deflation valve 114, thereby completing the deflation of the neck support body 11. It should be noted that the above-mentioned inflation and deflation take a long time, and only the inflation and deflation of the neck support body 11 are achieved, and rapid deflation cannot be completed. When the neck support body 11 is inflated, the air pressure in the first accommodating cavity 111 is greater than the external air pressure. In a specific embodiment, the air pressure in the first accommodating cavity 111 is 200 kPa.

[0047] One end of the connecting strap 12 can be connected to the neck support body 11. In some embodiments, the connecting strap 12 and the neck support body 11 can be constructed as an integral structure. A connecting channel 121 is formed inside the connecting strap 12, and the connecting channel 121 can be connected to the first accommodating cavity 111. In a specific embodiment, the connecting strap 12 can be constructed into two and respectively located on both sides of the neck support body 11 in the width direction of the vehicle. The connecting strap 12 can be constructed into an arc shape and be arranged around the headrest 21 of the seat 20.

[0048] like Figure 1 and Figure 2As shown, further, the neck support assembly 10 further includes a deflation device 13, which can be arranged at the seat 20, and a guide rod 22 for mounting a headrest 21 can be formed on the seat 20, and the deflation device 13 can be fixed to the guide rod 22, wherein the deflation device 13 and the guide rod 22 can be detachably connected by screws or bolts, or a mounting bracket 23 can be welded on the guide rod 22, and the deflation device 13 can be connected to the mounting bracket 23. The deflation device 13 can close the connecting channel 121, thereby ensuring that the gas in the first accommodating cavity 111 does not flow out through the connecting channel 121. Among them, when the vehicle collides, the deflation device 13 can open the connecting channel 121. At this time, the gas in the first accommodating chamber 111 is quickly discharged to the outside through the connecting channel 121 under the influence of pressure, completing the rapid deflation of the neck support body 11, preventing the user's cervical spine from colliding with the neck support body 11 under the influence of inertia and being damaged, thereby improving the safety of the neck support assembly 10. The above-mentioned collision may refer to a rear-end or side-on collision of the vehicle, and the user's neck moves backward or sideways due to inertia.

[0049] The collar body 11, the connecting belt 12 and the deflation device 13 are movably connected, that is, the collar body 11 can be adjusted within a certain range in the height direction of the vehicle, ensuring that the collar assembly 10 can be adapted to users of different body shapes.

[0050] In short, the neck support assembly 10 for a vehicle in the embodiment of the present application comprises a neck support body 11 and an air release device 13, the neck support body 11 and the air release device 13 are connected by a connecting belt 12, a first accommodating cavity 111 is formed inside the neck support body 11, a connecting channel 121 communicating with the first accommodating cavity 111 is formed inside the connecting piece, the air release device 13 can close the connecting channel 121, when the vehicle collides, the air release device 13 can open the connecting channel 121, at this time, the gas in the first accommodating cavity 111 can be quickly discharged to the outside through the connecting channel 121, to ensure that the neck support body 11 is deflated before the collision with the user's neck, thereby avoiding damage to the user's neck and improving the safety and reliability of the neck support assembly 10.

[0051] like Figure 3 and Figure 4As shown, in some embodiments of the present application, the deflation device 13 includes a first mounting plate 131 and a movable plate 132. Optionally, the first mounting plate 131 can be connected to the guide rod 22 of the headrest 21 or to the mounting bracket 23 at the guide rod 22. A first sealing portion 1311 can be formed on the first mounting plate 131, and the movable plate 132 can be arranged on the first mounting plate 131, and a second sealing portion 1321 corresponding to the first sealing portion 1311 can be formed on the movable plate 132. The first sealing portion 1311 can cooperate with the second sealing portion 1321 to press the other end of the connecting belt 12, thereby closing the connecting channel 121. It should be noted that the other end of the connecting belt 12 can be located between the first mounting plate 131 and the movable plate 132. The first sealing portion 1311 and the second sealing portion 1321 can be constructed as sealing strips. Grooves for installing a first sealing portion 1311 and a second sealing portion 1321 are respectively formed on a mounting plate 131 and a movable plate 132. The first sealing portion 1311 and the second sealing portion 1321 can be constructed as a "U" shape extending toward each other. By abutting the first sealing portion 1311 with the second sealing portion 1321, the connecting belt 12 between the first sealing portion 1311 and the second sealing portion 1321 can be clamped to close the connecting channel 121, thereby ensuring that the gas in the neck support body 11 does not leak, so that the neck support body 11 can effectively support the user's neck and complete the sealing of the first accommodating cavity 111.

[0052] In a specific embodiment, the first sealing portion 1311 can be constructed as two spaced apart in the width direction, and the second sealing portion 1321 can also be constructed as two, and each second sealing portion 1321 is arranged one-to-one with each first sealing portion 1311, and the two groups of first sealing portions 1311 and second sealing portions 1321 can be clamped at two connecting portions respectively to achieve sealing of the first accommodating cavity 111.

[0053] like Figure 6As shown, in some embodiments of the present application, the deflation device 13 also includes a second mounting plate 133, and the second mounting plate 133 can be connected to the side of the first mounting plate 131 facing away from the seat 20, wherein the second mounting plate 133 and the first mounting plate 131 can be detachably connected by bolts and threads, or the second mounting plate 133 and the first mounting plate 131 can be detachably connected by snapping or plugging. In a specific embodiment, the second mounting plate 133 and the first mounting plate 131 can be connected by bolts. Furthermore, a fixing plate is provided on the first mounting plate 131 or the second mounting plate 133, and the fixing plate can be bolted to the mounting plate of the seat guide rail, or corresponding fixing plates are formed on the first mounting plate 131 and the second mounting plate 133, respectively, and bolt holes correspondingly arranged in the thickness direction are formed on the fixing plates of the first mounting plate 131 and the second mounting plate 133, and the deflation device 13 is installed on the seat by sequentially passing the bolts through the fixing plate of the second mounting plate 133 and the fixing plate of the first mounting plate 131 and connecting them to the mounting plate of the seat guide rail, wherein reinforcing ribs are formed on the fixing plate of the first mounting plate 131 to improve the overall strength of the fixing plate.

[0054] like Figure 7 As shown, the second mounting plate 133 is spaced apart from the first mounting plate 131 to form a second accommodating chamber 134, and the movable plate 132 can be accommodated in the second accommodating chamber 134 and abut against the first mounting plate 131. When the vehicle collides, the movable plate 132 can move toward the second mounting plate 133, thereby separating the first sealing portion 1311 and the second sealing portion 1321. Due to the separation of the first sealing portion 1311 and the second sealing portion 1321, the connecting channel 121 is opened, and the gas in the first accommodating chamber 111 is quickly discharged to the outside through the connecting channel 121 under the influence of pressure, completing the rapid deflation of the neck support body 11, preventing the user's cervical vertebra from colliding with the neck support body 11 under the influence of inertia and being damaged, thereby improving the safety of the neck support assembly 10.

[0055] like Figure 7 and Fig. 9As shown, in some embodiments of the present application, a first elastic member 135 is further provided in the second accommodating cavity 134, one end of the first elastic member 135 can abut against the side of the movable plate 132 away from the first mounting plate 131, and the other end of the first elastic member 135 abuts against the second mounting plate 133. The first elastic member 135 can make the movable plate 132 abut against the first mounting plate 131, ensuring that the first sealing portion 1311 can cooperate with the second sealing portion 1321 to seal the connecting channel 121. The use of the first elastic member 135 can ensure that before the vehicle collides, the first elastic member 135 can apply a force to the movable plate 132 to make it abut against the first mounting plate 135. After the vehicle collides, the movable plate 132 can move toward the second mounting plate 133 and compress the first elastic member 135. In a specific embodiment, the first elastic member 135 can be constructed as a spring.

[0056] like Figure 5 and Figure 6 As shown, in some embodiments of the present application, a first sliding portion 1322 is formed at the outer peripheral wall of the movable plate 132, and the first sliding portion 1322 can be constructed as a plurality of first sliding portions 1322, and the plurality of first sliding portions 1322 can be arranged at intervals in the circumferential direction of the movable plate 132, and the inner wall of the second mounting plate 133 is formed with a second sliding portion 1331 which is arranged in a one-to-one correspondence with the plurality of first sliding portions 1322, and the second sliding portion 1331 can extend toward the first sliding portion 1322, and the first sliding portion 1322 can cooperate with the second sliding portion 1331 to realize the movable plate 132 and the second mounting plate 133. The radial limit between the plates 133 ensures that the movable plate 132 can move smoothly toward the second mounting plate 133. At the same time, the first elastic member 135 can effectively support the movable plate 132 to prevent the movable plate 132 from tilting, thereby improving the sealing effect between the first sealing portion 1311 and the second sealing portion 1321. In a specific embodiment, the first sliding portion 1322 can be constructed as a slide groove, and the second sliding portion 1331 can be constructed as a slider. The outer surface of the slider can fit with the inner surface of the slide groove, thereby ensuring that the first sliding portion 1322 can slide on the second sliding portion 1331.

[0057] like Figure 5 As shown, in some embodiments of the present application, a first clamping portion 1323 is formed on the movable plate 132, and a second clamping portion 1332 cooperating with the first clamping portion 1323 is formed on the second mounting plate 133, and the second clamping portion 1332 can be extended toward the movable plate 132, and the first clamping portion 1323 can be clamped with the second clamping portion 1332, thereby ensuring that when the movable plate 132 moves toward the second mounting plate 133, the movable plate 132 can be clamped with the second mounting plate 133, ensuring that the first sealing portion 1311 can always remain separated from the second sealing portion 1321, so that the connecting channel 121 is in an open state, and the gas in the first accommodating chamber 111 can be discharged to the outside in time.

[0058] Further, the first clamping portion 1323 can be configured as a clamping block, the second clamping portion 1332 can be configured as a clamping protrusion, the movable plate 132 can be formed with a through hole penetrating in the thickness direction, the clamping protrusion can be penetrated through the through hole and clamped with the clamping block, specifically, a clamping end is formed on the clamping protrusion, when the clamping protrusion passes through the through hole, the clamping end can abut against the surface of the clamping block, thereby limiting the movement of the clamping protrusion, and realizing the clamping of the movable plate 132 with the second mounting plate 1 33 is fixed by the clamping, and a reset spring 1324 is also provided on the clamping block. When the clamping protrusion moves toward the through hole, the clamping block first contacts with the surface of the clamping protrusion and compresses the reset spring 1324. After the clamping protrusion completely passes through the through hole, the reset spring 1324 drives the clamping block to move, so that the clamping block abuts against the clamping end and realizes the limitation in the thickness direction. The staff can separate the movable plate 132 from the second mounting plate 133 by moving the slider and compressing the reset spring 1324.

[0059] like Figure 4 and Figure 5 As shown, in some embodiments of the present application, a mounting groove 1312 is formed on one side of the first mounting plate 131 facing the movable plate 132, and the mounting groove 1312 can be extended toward the inside of the first mounting plate 131. A mounting protrusion 1325 extending toward the mounting groove 1312 is formed on the movable plate 132, and the mounting protrusion 1325 can be received in the mounting groove 1312, and the mounting protrusion 1325 can be sealed and fitted with the inner wall of the mounting groove 1312. Further, the mounting protrusion 1325 can slide along the mounting groove 1312, so as to realize The limiting function between the movable plate 132 and the first mounting plate 131 is realized, ensuring that the first sealing portion 1311 and the second sealing portion 1321 can be arranged opposite to each other. The mounting protrusion 1325 also has a guiding function, ensuring that after a collision of the vehicle, the movable plate 132 can move away from the first mounting plate 131 along the axial direction of the mounting protrusion 1325, thereby realizing the radial limiting function between the movable plate 132 and the first mounting plate 131. In a specific embodiment, the mounting groove 1312 can be constructed as a cylindrical groove, and the mounting protrusion 1325 can be constructed as a cylinder.

[0060] like Figure 2As shown, in some embodiments of the present application, the neck support assembly 10 also includes a driving device 14, which can be arranged on the first mounting plate 131, and the driving device 14 can be connected to the mounting groove 1312, and the driving device 14 can drive the mounting protrusion 1325 to move in a direction away from the mounting groove 1312, thereby separating the first sealing portion 1311 from the second sealing portion 1321, and then opening the connecting channel 121, and the gas in the first accommodating chamber 111 can be quickly discharged to the outside through the connecting channel 121 to ensure that the neck support body 11 is deflated before colliding with the user's neck. Specifically, the driving device 14 drives the mounting protrusion 1325 to disengage from the mounting groove 1312 to drive the movable plate 132 to move in a direction away from the first mounting plate 131, and when the movable plate 132 moves a certain distance, it is engaged and fixed with the second mounting plate 133, thereby separating the first sealing portion 1311 from the second sealing portion 1321.

[0061] like Figure 3 As shown, in some embodiments of the present application, the driving device 14 can be configured as a gas generator 141, and a pressure cap 142 is further provided on the gas generator 141. The inner wall of the pressure cap 142 is formed with a first threaded portion, and the first mounting plate 131 is formed with a second threaded portion that matches the first threaded portion. The gas generator 141 can be arranged inside the pressure cap 142, and the gas generator 141 can be electrically connected to the control unit 102 of the vehicle. It can be understood that the gas generator 141 is connected to the control unit 102 through the wire 101, as shown in FIG. Fig. 9 and Fig.10 As shown, when the vehicle collides, the gas generator 141 is ignited, the gunpowder in the gas generator 141 burns and then ignites the gas-producing powder, thereby achieving the effect of quickly generating a large amount of gas, and the gas is discharged into the installation groove 1312. Under the influence of air pressure, the installation protrusion 1325 is driven to detach from the installation groove 1312, thereby separating the first sealing part 1311 from the second sealing part 1321, so that the gas in the first accommodating cavity 111 can be quickly discharged to the outside through the connecting channel 121.

[0062] In other embodiments, the gas generator 141 can be replaced by a small high-pressure tank containing high-pressure gas. When the vehicle collides, the gas in the high-pressure tank is released into the mounting groove 1312 and pushes the mounting protrusion 1325 to move in a direction away from the mounting groove 1312, thereby separating the first sealing portion 1311 from the second sealing portion 1321. The release of the high-pressure tank can be achieved by detonation. The neck support assembly 10 adopts the control system of the vehicle's passive safety system, which is more reliable.

[0063] In other embodiments of the present application, the drive device 14 can be constructed as an electromagnet and a second elastic member. The second elastic member can be arranged between the end of the mounting protrusion 1325 and the mounting groove 1312. The second elastic member can be compressed by a locking member, and the locking member is controlled by the electromagnet. The elastic force of the second elastic member is greater than that of the first elastic member 135. When the vehicle collides, the control unit 102 of the vehicle energizes the electromagnet, and the electromagnet controls the locking member to disengage from the second elastic member. The second elastic member drives the mounting protrusion 1325 to move in a direction away from the mounting groove 1312 due to the elastic force until the movable plate 132 is engaged with the second mounting plate 133, thereby achieving the effect of separating the first sealing portion 1311 from the second sealing portion 1321, ensuring that the gas in the neck support body 11 can be discharged to the outside in time, achieving the deflation of the neck support body 11, and ensuring the safety of the driver and passengers.
