Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a seat anti-submersion device, a seat, and a vehicle. Background Technology

[0002] Currently, users have high requirements for seat comfort in vehicles.

[0003] In related technologies, to improve the user's riding experience, the seat cushion is typically designed to be softer by lowering the seat height and increasing the cushion thickness, resulting in a greater depth of sinking when the user sits on the cushion. However, in the event of a sudden incident (such as a frontal collision, offset collision, or emergency braking), the user will tend to move forward relative to the seat. This can prevent the lap belt portion of the seatbelt from effectively engaging with the occupant's iliac crest, causing the lap belt to exert a greater restraining force on the occupant's abdomen and affecting the seatbelt's protective effect. Utility Model Content

[0004] In view of this, this application aims to provide a seat anti-submersion device to improve the anti-submersion effect of the seat when a vehicle collision occurs.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows:

[0006] A seat anti-submersion device is applied to a vehicle and includes: a seat basin assembly, the seat basin assembly including a first seat basin and a second seat basin arranged along the X-direction of the vehicle, and the first seat basin being located in front of the second seat basin; an anti-submersion component, the anti-submersion component including: an anti-submersion bar, the anti-submersion bar being fixedly connected to the first seat basin, and the second seat basin being rotatable about a first axis of the anti-submersion bar; and a drive component, the drive component being mounted on the seat basin assembly and connected to the second seat basin, and used to drive the side of the second seat basin away from the first seat basin to lift upward.

Detailed Implementation

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0040] The following will refer to the appendix. Figure 1 - Appendix Figure 7 The seat anti-submersion device 10 of this application is described in detail with reference to the embodiments. The seat anti-submersion device 10 is applied to the seat 100 of a vehicle and can prevent the user from submerging at the seat 100.

[0041] According to an embodiment of this application, the seat anti-submersion device 10 includes a seat basin assembly 1 and an anti-submersion assembly 2.

[0042] The seat assembly 1 in the seat 100 provides support for the legs of the driver and passenger, allowing them to be in a position suitable for use with the seat belt, thereby providing effective protection for the driver and passenger through the seat belt.

[0043] like Figure 1 and Figure 3 As shown, the seat basin assembly 1 includes a first seat basin 11 and a second seat basin 12 arranged along the X direction of the vehicle, and the first seat basin 11 is located in front of the second seat basin 12. That is to say, when the driver or passenger sits on the seat 100, the seat basin assembly 1 can support the thighs of the driver or passenger.

[0044] It should be noted that the "X-direction" is the front-to-back direction in the vehicle coordinate system, that is, the first seat 11 and the second seat 12 are arranged in the front-to-back direction.

[0045] Combination Figure 1 , Figure 3 and Figure 7 It can be seen that in the seat 100, the rear area of ​​the seat basin assembly 1 can be filled by a support structure such as the seat cushion 20 to improve the comfort of the seat 100. Among them, the seat cushion 20 has lower strength than the seat basin assembly 1, and can better conform to the buttocks and legs of the driver and passenger to improve the comfort of the seat 100.

[0046] Furthermore, the anti-submersion assembly 2 includes an anti-submersion bar 21 and a drive assembly 22. The anti-submersion bar 21 is fixedly connected to the first seat 11, and the second seat 12 is configured to rotate about the first axis of the anti-submersion bar 21 so that the seat assembly 1 can support the driver and passengers by adjusting the position of the second seat 12.

[0047] The drive assembly 22 is mounted on the seat assembly 1 and is connected to the second seat 12. The drive assembly 22 is used to drive the side of the second seat 12 away from the first seat 11 to lift upward, so as to increase the support effect of the rear area of ​​the seat assembly 1 on the driver and passengers and effectively prevent the driver and passengers from sinking.

[0048] Understandably, since the first seat basin 11 and the second seat basin 12 are arranged in the front-to-back direction, the side of the second seat basin 12 that is away from the first seat basin 11 in the front-to-back direction is also the rear side of the second seat basin 12. The rear part of the second seat basin 12 is driven to lift upward by the drive assembly 22, so that the second seat basin 12 can provide upward support for the legs (or buttocks) of the driver and passenger, effectively preventing the driver and passenger from falling down and ensuring that the seat belt can effectively protect the driver and passenger.

[0049] It should be noted that currently, users in vehicles have high requirements for the comfort of seat 100. In related technologies, to improve the user's riding experience, the seat cushion 20 is typically designed to be softer by lowering the seat height and increasing the thickness of the seat cushion 20, resulting in a greater depth of sinking when the user sits on it. If the vehicle encounters a sudden situation (such as a frontal collision, offset collision, or emergency braking), the user will tend to move forward relative to the seat 100. This causes the lap belt portion of the seatbelt to not effectively engage with the occupant's iliac crest, resulting in a greater restraining force on the occupant's abdomen and affecting the seatbelt's protective effect.

[0050] In this application, the seat pan assembly 1 of the seat anti-submersion device 10 consists of two parts: a first seat pan 11 and a second seat pan 12. The position of the first seat pan 11 is fixed in the seat 100 to ensure the support effect of the first seat pan 11 on the legs of the driver and passenger. The second seat pan 12 can cooperate with the anti-submersion component 2 so that the second seat pan 12 can rotate around the first axis under the drive of the anti-submersion component 2. The rear part of the second seat pan 12 can be lifted up to provide upward support for the legs of the driver and passenger. In this way, by raising the seat pan assembly 1, the cooperation effect between the driver and passenger and the lap belt part of the seat belt is improved, effectively preventing the driver and passenger from submerging, improving the safety of the driver and passenger when driving the vehicle, and being able to fully cope with emergencies.

[0051] like Figure 2 and Figure 4 As shown, in some embodiments of this application, the drive assembly 22 includes an anti-submarine support 221 and a drive device 222.

[0052] The anti-submarine support 221 is fixedly connected to the second basin 12 so that the second basin 12 can move synchronously through the anti-submarine support 221. The drive device 222 is installed at the first basin 11 and is located between the first basin 11 and the anti-submarine support 221 so that the anti-submarine support 221 can be driven to rotate around the first axis through the drive device 222.

[0053] It is understood that the drive device 222 is used to cooperate with the anti-submarine support 221 so that when it is necessary to adjust the position of the second seat 12 (i.e. the angle of the second seat 12), the drive device 222 applies driving force to the anti-submarine support 221, and the anti-submarine support 221 further drives the second seat 12 to rotate around the first axis, thereby realizing the position adjustment of the second seat 12.

[0054] Combination Figure 2 and Figure 4 As shown in a further embodiment of this application, the drive assembly 22 further includes a bushing 23, which is connected to the surface of the anti-submarine bracket 221 opposite to the anti-submarine rod 21. The bushing 23 can cooperate with the outer peripheral surface of the anti-submarine rod 21 to make the anti-submarine bracket 221 rotate around the first axis.

[0055] Among them, the bushing 23 is arranged on the circumferential outer side of the anti-submarine rod 21. Through the cooperation between the bushing 23 and the anti-submarine rod 21, it can play an auxiliary role in the movement of the anti-submarine support 221 relative to the anti-submarine rod 21, so as to improve the movement stability of the anti-submarine support 221 relative to the anti-submarine rod 21 around the first axis.

[0056] It should be noted that the bushing 23 and the anti-submarine support 221 are fixedly connected. The specific structure of the bushing 23 and the way it cooperates with the anti-submarine rod 21 are not specifically limited here. In some embodiments, the bushing 23 is provided with a through hole, and the bushing 23 can be sleeved on the anti-submarine rod 21 through the through hole to realize the connection and cooperation between the bushing 23 and the anti-submarine rod 21. In other embodiments, the bushing 23 is provided with a sliding groove. When the bushing 23 and the anti-submarine support 221 are fixedly connected, the wall of the sliding groove is arranged in close contact with the outer peripheral wall of the anti-submarine rod 21 to improve the reliability of the cooperation between the bushing 23 and the anti-submarine rod 21. The anti-submarine rod 21 is arranged between the sliding groove formed by the bushing 23 and the anti-submarine support 221 to guide the movement of the anti-submarine support 221.

[0057] Combination Figure 2 and Figure 4 As shown, Figure 2 The second seat basin 12 in the seat anti-submersion device 10 shown in the figure is in the initial position, that is, the drive assembly 22 is not driving the second seat basin 12. Figure 4 The second seat basin 12 in the seat anti-submersion device 10 shown is in the anti-submersion position, that is, the drive assembly 22 drives the anti-submersion bracket 221 to rotate and lift the rear of the second seat basin 12 upward. It is understood that, compared to... Figure 2 The content shown, Figure 4 The drive device 222 and the anti-submarine support 221 are exposed in the middle, thus demonstrating the effect of the drive device 222 and the anti-submarine support 221 working together, that is, the drive device 222 drives the anti-submarine support 221 to rotate around the anti-submarine rod 21.

[0058] Combination Figure 2 and Figure 4 As shown, in some embodiments of this application, the anti-submarine support 221 includes a first plate segment 2211 and a second plate segment 2212. At least a portion of the first plate segment 2211 is disposed opposite to the driving device 222, so that the driving force generated by the driving device 222 can be fully applied to the first plate segment 2211. The second plate segment 2212 is connected to the rear end of the first plate segment 2211 and is fixedly connected to the second seat basin 12 so as to drive the second seat basin 12 to move synchronously through the second plate segment 2212.

[0059] It is understood that the first plate segment 2211 is used to cooperate with the drive device 222 to receive the driving force output by the drive device 222. The second plate segment 2212 is fixedly set with the first plate segment 2211, and the second plate segment 2212 can move synchronously under the drive of the first plate segment 2211 to further transmit the driving force to the second seat 12, so as to realize the drive component 22 to drive the second seat 12.

[0060] like Figure 2 As shown, in some embodiments of this application, the second plate segment 2212 is provided with reinforcing ribs 2213 to improve the structural strength of the second plate segment 2212, thereby ensuring the driving force transmission effect between the second plate segment 2212 and the second seat 12.

[0061] In some optional embodiments of this application, the reinforcing ribs 2213 extend along the front-back direction on the second plate segment 2212, and there are multiple reinforcing ribs 2213. The multiple reinforcing ribs 2213 are arranged sequentially in the width direction of the second plate segment 2212 to fully improve the structural strength of the second plate segment 2212.

[0062] like Figure 1 and Figure 3 As shown, in some embodiments of this application, the second basin 12 is formed with a boss 121. The boss 121 protrudes to one side along the thickness direction of the second basin 12, so as to improve the local structural strength of the second basin 12 by setting the raised structure (i.e. the boss 121 mentioned above), thereby improving the reliability of the second basin 12 in bearing the driving force.

[0063] Among them, the reinforcing rib 2213 of the second plate segment 2212 is connected and matched with the boss 121 of the second seat basin 12. The shape of the reinforcing rib 2213 and the boss 121 are mutually compatible to improve the reliability of the fit between the second plate segment 2212 and the second seat basin 12 and ensure the driving force transmission effect.

[0064] Combination Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments of this application, the drive device 222 includes a fixed base 2221, a drive rod 2222, and a generator 2223.

[0065] The mounting base 2221 is fixed to the first basin 11, and the mounting base 2221 has a receiving groove 2225 that opens to one side of the anti-submarine support 221. The receiving groove 2225 is used to arrange the drive rod 2222 and the generator 2223. At the same time, the arrangement position of the mounting base 2221 in the first basin 11 can be designed according to the anti-submarine support 221 to ensure the cooperation effect between the drive rod 2222 and the anti-submarine support 221.

[0066] Furthermore, at least a portion of the drive rod 2222 is arranged within the receiving groove 2225, and the first end of the drive rod 2222 within the receiving groove 2225 defines a generating cavity 2226 with the fixed seat 2221. A generator 2223 is arranged within the generating cavity 2226, and the generator 2223 is adapted to generate gas upon triggering to push the drive rod 2222 outward from the receiving groove 2225. The second end of the drive rod 2222 is used to drive the anti-submarine support 221 to engage, so that the driving force at the drive rod 2222 is applied to the anti-submarine support 221 to achieve the flipping action of the anti-submarine support 221.

[0067] Understandably, the drive rod 2222 is configured to extend outward from the outside of the receiving groove 2225 (also towards the anti-submarine support 221 side) to transmit driving force to the anti-submarine support 221. The generator 2223 can be configured as a gunpowder generator. When the generator 2223 is triggered, it can generate significant energy within the generating chamber 2226, such as generating a large amount of heat or gas. Due to the limited volume of the generating chamber 2226, the energy can be fully applied to the drive rod 2222, which defines the generating chamber 2226, thus pushing the drive rod 2222 outward. Simultaneously, during the outward extension of the drive rod 2222, the force can be transmitted to the anti-submarine support 221, thereby driving the anti-submarine support to rotate.

[0068] like Figure 5 As shown in some embodiments of this application, the drive device 222 further includes a buffer end 2224. The buffer end 2224 is located at the second end of the drive rod 2222, and can engage with the anti-submarine bracket 221 when the drive rod 2222 extends. The buffer end 2224 can buffer the impact force to a certain extent, thereby avoiding problems such as the drive rod 2222 penetrating the anti-submarine bracket 221 due to excessive driving force. At the same time, it can also prevent the anti-submarine bracket 221 from squeezing the drive rod 2222 during normal use and causing abnormal noise.

[0069] In a further embodiment of this application, the buffer end 2224 can be constructed as a rubber part. The rubber part has a certain structural strength and can be squeezed and deformed when subjected to force to increase the contact area between the buffer end 2224 and the anti-submarine bracket 221, thereby ensuring the transmission effect of driving force.

[0070] like Figure 6As shown, in some embodiments of this application, there are multiple generators 2223, all of which are located within the generating chamber 2226, and each generator 2223 can be triggered individually. That is, the multiple generators 2223 can be individually controlled according to the position adjustment requirements of the second seat 12. Taking two generators 2223 in the generating chamber 2226 as an example, when a larger driving force is required from the driving device 222, both generators 2223 can be controlled to trigger simultaneously; when a smaller driving force is required from the driving device 222, only one of the two generators 2223 can be controlled to trigger.

[0071] It is understandable that there are differences in body size among the occupants using seat 100. If the occupants are relatively tall, the drive unit 222 needs to output a larger driving force when the seat anti-submarine device 10 performs anti-submarine protection to support the occupants. If the occupants are relatively thin, the drive unit 222 can output a smaller driving force when the seat anti-submarine device 10 performs anti-submarine protection to meet the support needs of the occupants.

[0072] In some embodiments of this application, when the drive device 222 is in a non-driven state, the second end of the drive rod 2222 can be spaced apart from the anti-submarine support 221 to reduce the risk of false triggering of the generator 2223. It is understood that when a passenger sits on the seat cushion 20, the passenger's weight can be fed back onto the second seat basin 12. If the second seat basin 12 drives the anti-submarine support 221 to move, there is a risk that the anti-submarine support 221 will squeeze the drive device 222. Therefore, by spaced apart from the second end of the drive rod 2222 from the anti-submarine support 221, the risk of the drive device 222 being falsely triggered can be reduced.

[0073] like Figure 2 and Figure 4 As shown, in some embodiments of this application, the anti-submersion component 2 further includes a mounting bracket 25, which is mounted on the first basin 11 and fixedly connected to the anti-submersion rod 21. Thus, the first basin 11 and the anti-submersion rod 21 are fixedly connected by the mounting bracket 25, which is a simple and highly reliable connection method.

[0074] Furthermore, the mounting bracket 25 is constructed as two, and the two mounting brackets 25 are arranged at intervals along the axial direction of the anti-submersion rod 21 on the first seat 11, so as to improve the connection strength between the first seat 11 and the anti-submersion rod 21 by increasing the number of mounting brackets 25.

[0075] like Figure 2As shown, in some embodiments of this application, the first basin 11 is provided with a first lug 111, and the first basin 11 is hung on the anti-submarine bar 21 through the first lug 111, so as to further improve the connection reliability between the first basin 11 and the anti-submarine bar 21.

[0076] like Figure 1 As shown, in some embodiments of this application, the second basin 12 is provided with a second lug 122, and the second basin 12 is hung on the anti-submarine bar 21 through the second lug 122, so as to limit the anti-submarine bar 21 through the hanging structure formed on the second lug 122.

[0077] The following describes two operating conditions of the seat anti-submersion device 10 according to an embodiment of this application:

[0078] When the seat anti-submarine device 10 is not triggered, there is no obvious relative movement between the components in the seat anti-submarine device 10, and the seat cushion 20 located at the second seat basin 12 has a relatively thick depth, so that the seat 100 is in a relatively comfortable sitting state.

[0079] When the vehicle encounters an emergency, the control generator 2223 is ignited. The drive rod 2222 extends outward from the receiving groove 2225 under the driving force generated by the generator 2223, and transmits the force to the anti-submarine bracket 221 through the buffer end 2224. The anti-submarine bracket 221 can drive the second seat 12 to rotate, so as to support the driver and passengers by raising the rear area of ​​the seat assembly 1, ensuring the cooperation effect between the driver and passengers and the seat belt, and effectively preventing the driver and passengers from falling.

[0080] It should be noted that the tilting angle (e.g., 5°, 10°, etc.) of the second seat 12 driven by the drive unit 222 is not specifically limited here, and can be adaptively adjusted according to the body shape and weight of the driver and passengers. Meanwhile, the aforementioned emergency situations include, but are not limited to, emergency braking of the vehicle, frontal collision, and offset collision.

[0081] In summary, the seat anti-submersion device 10 according to the embodiments of this application has at least the following advantages over the prior art:

[0082] (1) The seat pan assembly 1 in the seat anti-submersion device 10 consists of two parts: a first seat pan 11 and a second seat pan 12. The second seat pan 12 can cooperate with the anti-submersion assembly 2 so that the second seat pan 12 can rotate around the first axis under the drive of the anti-submersion assembly 2. The rear part of the second seat pan 12 can be lifted up to provide upward support for the legs of the driver and passenger. By raising the seat pan assembly 1, the cooperation effect between the driver and passenger and the lap belt part of the seat belt is improved, effectively preventing the driver and passenger from submerging and ensuring the cooperation effect between the driver and passenger and the seat belt. This can take into account both the comfort and safety of the seat 100.

[0083] (2) The drive unit 222 is equipped with multiple generators 2223, which can apply corresponding support force to the driver and passenger based on the driver's height, weight and other information, so that the seat anti-submersion device 10 can match users of various body types.

[0084] (3) The connection between the anti-submarine support 221 and the second seat 12 is highly reliable, which can ensure the stability and reliability of the transmission of driving force, and can quickly transmit the driving force to the anti-submarine rod 21, so that the anti-submarine rod 21 can participate in the action as soon as possible.
