Detailed implementation manners

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present application belong to the scope of protection of the present application.

[0025] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0026] The seat assembly and vehicle provided by the present invention will be described in detail below with reference to the embodiments.

[0027] The descriptions of various directions in the present application refer to the orientation when the seat assembly is installed on the vehicle and works normally. The front-rear direction is the direction from the front of the vehicle to the rear of the vehicle; the left-right direction is the left-right direction of the vehicle, approximately horizontal; the up-down direction is the direction from the roof of the vehicle to the rear of the vehicle, approximately perpendicular to the bottom surface.

[0028] Please refer to Figures 1 to 3 , Figure 1It is an exploded structural schematic diagram of an embodiment of the seat assembly of the present application, which includes a seat, a sliding member, a fixed seat, a limiting assembly, a limiting assembly, a propulsion assembly, a propulsion link, a collision sensor and a wire harness; Figure 2 is Figure 1 the assembled structural schematic diagram; Figure 3 is Figure 1 The structural schematic diagram of the seat assembly in with the seat removed. The present application provides a seat assembly 1. The seat assembly 1 includes a seat 10, a sliding member 20, a fixed seat 30, a limiting assembly 40 and a propulsion assembly 50. The sliding member 20 is connected to the seat 10. The fixed seat 30 is connected to the vehicle body (not shown in the figure).

[0029] Sliding grooves 21 extending along the first direction D1 are provided on both sides of the sliding member 20. The fixed seat 30 includes two fixed rods 311 extending along the first direction D1. The sliding member 20 is respectively connected to the two fixed rods 311 through the sliding grooves 21 on both sides. At least part of the fixed rod 311 is embedded in the corresponding sliding groove 21. The fixed rod 311 can guide the movement of the sliding member 20, so that the sliding member 20 maintains the correct position and direction during the movement. In a specific embodiment, the first direction D1 may be the front-rear direction of the vehicle, that is, the direction from the vehicle head to the vehicle tail. The two fixed rods 311 are respectively arranged on the left and right sides of the seat 10. Such an arrangement facilitates the sliding member 20 to drive the seat 10 connected to the sliding member 20 to move backward when moving relative to the fixed rod 311.

[0030] The limiting assembly 40 is detachably locked between the fixed rod 311 and the sliding groove 21. In the normal state, the limiting assembly 40 is locked between the fixed rod 311 and the sliding groove 21, so that the sliding member 20 and the fixed rod 311 cooperate with each other and do not move relative to each other, forming a stable support structure for the seat 10. When a vehicle collision occurs, the limiting assembly 40 releases the connection relationship between the fixed rod 311 and the sliding groove 21, and the sliding member 20 moves relative to the fixed rod 311, thereby driving the seat 10 connected to the sliding member 20 to move backward.

[0031] The propulsion assembly 50 is connected to the sliding member 20. The propulsion assembly 50 pushes the sliding member 20 to move along the fixed rod 311. A gas generator 51 is provided in the propulsion assembly 50. Wherein, when the gas generator 51 works, the limiting assembly 40 releases the connection between the fixed rod 311 and the sliding groove 21, and the propulsion assembly 50 pushes the sliding member 20 to move relative to the two fixed rods 311. The gas generator 51 is used to generate gas or pressure to push the sliding member 20 to move, thereby pushing the seat 10 connected to the sliding member 20 to move.

[0032] In the normal state, the limiting component 40 is locked between the fixed rod 311 and the sliding groove 21, so that the sliding member 20 and the fixed rod 311 cooperate with each other and do not move relative to each other, thereby maintaining the stability of the seat 10. When a vehicle collision occurs, the gas generator 51 immediately operates to generate gas or pressure. Since the gas generator 51 is connected to the propulsion assembly 50, the gas or pressure generated by the gas generator 51 pushes the sliding member 20 to move relative to the two fixed rods 311, and the limiting component 40 between the fixed rod 311 and the sliding groove 21 is released after being subjected to the thrust, thereby driving the seat 10 connected to the sliding member 20 to move backward.

[0033] In the above manner, when a vehicle collision occurs, the gas generator 51 can be operated to push the sliding member 20 to move along the fixed rod 311. The limiting component 40 between the fixed rod 311 and the sliding groove 21 is released after being subjected to the thrust, thereby driving the seat 10 connected to the sliding member 20 to move backward instantaneously, increasing the distance between the seat 10 and the vehicle head, obtaining more crushing space for energy absorption, reducing the risk of passengers being stuck between the vehicle head and the seat 10, thereby protecting the safety of passengers to the greatest extent, reducing the possibility of passengers being injured during vehicle collision, and improving the safety of the vehicle. And the sliding groove 21 of the sliding member 20 and the fixed rod 311 of the fixed seat 30 cooperate with each other, making the seat assembly 1 compact and saving the interior space of the vehicle.

[0034] In a specific embodiment, along the first direction D1, the length of the fixed rod 311 is greater than the length of the sliding groove 21, and the fixed rod 311 and the sliding groove 21 cooperate with each other and can move relative to each other. The moving distance of the sliding member 20 can be controlled by the fixed rod 311, thereby controlling the backward moving distance of the seat 10. For example, along the first direction D1, the fixed rod 311 is 100 mm - 500 mm longer than the sliding groove 21, so that the sliding member 20 can move 100 mm - 500 mm along the fixed rod 311.

[0035] The manner of arranging the sliding grooves 21 on both sides of the sliding member 20 can be set according to the actual situation and is not limited herein. In a specific embodiment, sliding grooves 21 are provided on both sides of the end face of the sliding member 20 close to the vehicle body. That is, sliding grooves 21 are provided at the bottom of the sliding member 20. In another specific embodiment, as Figure 3 shown, sliding grooves 21 are provided on the end faces of both ends of the sliding member 20. That is, fixed rods 311 are provided on the left and right sides of the sliding member 20, and at least part of the fixed rods 311 is embedded in the corresponding sliding grooves 21. Such a setting can effectively save space and reduce the space occupied by the connection between the fixed rod 311 and the sliding member 20. At the same time, the sliding member 20 can have higher stability during the movement along the fixed rod 311.

[0036] The type of the limiting component 40 can be set according to the actual situation and will not be limited here. In a specific embodiment, the limiting component 40 is an elastic member. In the normal state, the elastic member is compressed or stretched to deform, thereby generating a limiting force to prevent relative movement between the sliding groove 21 and the fixed rod 311; when the vehicle collides, the elastic member returns to its original state, enabling the sliding member 20 to move relative to the two fixed rods 311. In another specific embodiment, the limiting component 40 is a locking member. In the normal state, the locking member is located in the sliding groove 21 to prevent relative movement between the fixed rod 311 and the sliding groove 21; when the vehicle collides, the locking member disengages from the sliding groove 21, enabling the sliding member 20 to move relative to the two fixed rods 311.

[0037] In one embodiment, the limiting component 40 includes a limiting protrusion 41 and a limiting groove 42. Multiple limiting protrusions 41 are spacedly arranged on one of the outer periphery of the fixed rod 311 and the inner side wall of the sliding groove 21. Multiple limiting grooves 42 are spacedly arranged on the other of the outer periphery of the fixed rod 311 and the inner side of the sliding groove 21. The limiting groove 42 and the limiting protrusion 41 are releasably locked.

[0038] By setting the cooperation of the limiting protrusion 41 and the limiting groove 42, in the normal state, the limiting groove 42 can limit the limiting protrusion 41, reducing the possibility of relative movement between the sliding groove 21 and the fixed rod 311 and enhancing the reliability between the sliding member 20 and the fixed rod 311. When the vehicle collides, the sliding member 20 can directly move relative to the fixed rod 311, unaffected by the limiting protrusion 41 and the limiting groove 42, driving the seat 10 connected to the sliding member 20 to move backward quickly, so that the seat 10 moves backward instantaneously, reducing the collision injury of the passengers. And such a setting makes the structure of the limiting component 40 simple, easy to process, reducing the production cost and assembly difficulty.

[0039] In a specific embodiment, as Figure 1 shown, multiple limiting protrusions 41 are spacedly arranged on the outer periphery of the fixed rod 311, and multiple limiting grooves 42 are arranged on the inner wall of the sliding groove 21, and the limiting grooves 42 and the limiting protrusions 41 correspond to each other. In another specific embodiment, multiple limiting grooves 42 are spacedly arranged on the outer periphery of the fixed rod 311, and multiple limiting protrusions 41 are arranged on the inner wall of the sliding groove 21, and the limiting grooves 42 and the limiting protrusions 41 correspond to each other.

[0040] Please continue to refer to Figure 4 , Figure 4 is Figure 1Schematic diagram of the structure of the middle fixing bracket. In one embodiment, the fixing base 30 includes two fixing brackets 31. Each fixing bracket 31 includes a fixing rod 311 and two fixing mounts 312. The two fixing mounts 312 are respectively arranged at opposite ends of the fixing rod 311. The fixing mount 312 includes a first sub-fixing mount 3121 and a second sub-fixing mount 3122 perpendicular to the first sub-fixing mount 3121. That is to say, the fixing mount 312 is generally in an "L" - shaped structure, creating a space between the fixing rod 311 and the vehicle body. The first sub-fixing mount 3121 is used for mounting on the vehicle body. The ways of mounting the first sub-fixing mount 3121 on the vehicle body include but are not limited to screwing, bonding, welding, clamping, etc. The second sub-fixing mount 3122 is connected to the end of the fixing rod 311. The connection ways between the second sub-fixing mount 3122 and the fixing rod 311 include but are not limited to screwing, bonding, welding, clamping, etc.

[0041] By setting the first sub-fixing mount 3121 perpendicular to the second sub-fixing mount 3122, a space is created between the fixing rod 311 and the vehicle body, and at least part of the fixing rod 311 is embedded in the sliding groove 21 of the corresponding sliding member 20. In this way, an installation space is formed between the bottom of the sliding member 20 and the vehicle body through the four fixing mounts 312. And setting the fixing mount 312 can provide stable support for the seat 10 and the sliding member 20, reducing the shaking and offset of the sliding member 20 during movement.

[0042] Please refer to Figure 2 and Figure 3 , in one embodiment, an installation space is formed between the bottom of the sliding member 20 and the vehicle body through the four fixing mounts 312. The propulsion assembly 50 is located in the installation space. That is, the propulsion assembly 50 is located between the sliding member 20 and the vehicle body. Such a setting can make the structure of the seat assembly 1 more compact, effectively utilize the space at the bottom of the sliding member 20, and further save the interior space of the vehicle.

[0043] Please refer to Figure 3 and Figure 5 , Figure 5 is Figure 1 Schematic diagram of the structure of the seat in. In one embodiment, at least one seat mounting seat 11 is respectively arranged on both sides of the seat 10. Seat mounting holes 22 are respectively arranged on both sides of the sliding member 20. The number of seat mounting holes 22 corresponds to the number of seat mounting seats 11. A fixing member (not shown in the figure) passes through the seat mounting seat 11 and the seat mounting hole 22 to connect the seat mounting seat 11 and the sliding member 20. The types of the fixing member include but are not limited to bolts, screws, pins, etc. In other embodiments, the connection ways between the seat mounting seat 11 and the sliding member 20 include but are not limited to clamping, bonding, welding, etc.

[0044] Compared with the prior art which requires changes to the bottom structure of the seat 10 to connect the seat 10 with the sliding member 20. In this application, there is no need to make special changes to the structure of the seat 10. By passing a fixing member through the seat mounting base 11 and the seat mounting hole 22, the seat mounting base 11 can be connected with the sliding member 20. And by connecting the seat 10 and the sliding member 20 through the fixing member, the reliability of the connection between the seat 10 and the sliding member 20 is improved, so that when the sliding member 20 moves relative to the fixed seat 30, the seat 10 can move accordingly. At the same time, the installation process of the seat 10 is simplified, making the installation and disassembly of the seat 10 more convenient.

[0045] In a specific embodiment, four seat mounting bases 11 are provided at the bottom of the seat 10, with two seat mounting bases 11 provided on each side of the seat 10. The sliding member 20 is provided with corresponding four seat mounting holes 22, and the seat mounting holes 22 on both sides of the sliding member 20 are arranged close to the sliding groove 21. The fixing member passes through the seat mounting base 11 and the seat mounting hole 22 to connect the seat mounting base 11 and the sliding member 20. Such a setting can further enhance the stability of the seat 10 and reduce the displacement or looseness of the seat 10.

[0046] Please refer to Figure 3 and Figure 6 , Figure 6 is Figure 1 the schematic assembly structure diagram of the sliding member and the propulsion link in. In an embodiment, the seat assembly 1 includes a propulsion link 60. One end of the propulsion link 60 is connected to the side surface of the sliding member 20 facing away from the seat 10. The other end of the propulsion link 60 is connected to the propulsion assembly 50. That is to say, the propulsion link 60 and the propulsion assembly 50 are arranged in the installation space. By providing the propulsion link 60, a greater thrust can be provided for the movement of the sliding member 20.

[0047] When a vehicle collision occurs, the gas generator 51 of the propulsion assembly 50 works, and the gas or pressure generated by the gas generator 51 pushes the propulsion link 60 to move. The sliding member 20 moves relative to the two fixed rods 311 under the push of the propulsion link 60, thereby driving the seat 10 connected to the sliding member 20 to move backward.

[0048] The connection manner between the propulsion link 60 and the sliding member 20 can be set according to the actual situation and is not limited herein. In a specific embodiment, the propulsion link 60 and the sliding member 20 are integrally formed structures. In another specific embodiment, the propulsion link 60 and the sliding member 20 are fixedly connected, and the connection manners include but are not limited to welding, bonding, clamping, screwing, etc.

[0049] The shape of the propulsion connecting rod 60 can be set according to the actual situation and will not be limited here. In a specific embodiment, the propulsion connecting rod 60 is a straight structure, and the two ends of the propulsion connecting rod 60 are respectively connected to the sliding member 20 and the propulsion assembly 50. In another specific embodiment, as Figure 6 shown, the propulsion connecting rod 60 includes a first propulsion portion 61, a second propulsion portion 62, and a third propulsion portion 63. The first propulsion portion 61 is disposed on the side surface of the sliding member 20 facing away from the seat 10 along the first direction D1. The first propulsion portion 61 and the third propulsion portion 63 are arranged in parallel. The second propulsion portion 62 is arc-shaped. One end of the third propulsion portion 63 away from the second propulsion portion 62 is connected to the propulsion assembly 50. That is to say, the propulsion connecting rod 60 is a bent structure. The shape of the propulsion connecting rod 60 is generally a "U" - shaped structure. The sliding member 20 and the propulsion assembly 50 are arranged in parallel. The sliding member 20 and the propulsion assembly 50 are on the same side of the first direction D1, and the second propulsion portion 62 is on the other side of the first direction D1. Such a setting facilitates arranging the propulsion assembly 50 in the installation space and effectively saves the vehicle interior space. And the propulsion connecting rod 60 arranged in this way can withstand a large impact. When the vehicle collides, the propulsion connecting rod 60 can provide a greater thrust for the movement of the sliding member 20, so that the seat 10 moves backward instantly, reducing the collision damage of the passengers.

[0050] Please refer to Figure 3 and Figure 7 , Figure 7 is Figure 1 the exploded structural schematic diagram of the propulsion assembly in

[0051] When the vehicle collides, the gas generator 51 operates to generate gas or pressure. Since the gas generator 51 is connected to the piston cylinder 52, the gas or pressure generated by the gas generator 51 can push the valve 53 in the piston cylinder 52, causing the valve 53 to drive the propulsion link 60 to move in the direction of extending out of the piston cylinder 52. The sliding member 20 connected to the propulsion link 60 moves relative to the two fixed rods 311 under the push of the propulsion link 60. The limiting component 40 located between the fixed rod 311 and the sliding groove 21 is released after receiving the thrust, thereby driving the seat 10 connected to the sliding member 20 to move backward.

[0052] By arranging the valve 53 and a part of the third propulsion part 63 inside the piston cylinder 52, when the vehicle collides, the seat 10 can move backward quickly, reducing the collision damage to the passengers.

[0053] In one embodiment, the seat assembly 1 further includes a collision sensor 70. The collision sensor 70 is connected to the gas generator 51, and the connection methods include but are not limited to signal connection, wire harness connection, etc. In a specific embodiment, the collision sensor 70 is connected to the gas generator 51 through a wire harness 80. After receiving the signal from the collision sensor 70, the gas generator 51 operates. By arranging the collision sensor 70, when the vehicle collides, it can quickly respond to make the gas generator 51 operate immediately, so that the seat 10 moves backward quickly, further protecting the safety of the passengers.

[0054] In one embodiment, the gas generator 51 includes an igniter (not shown in the figure) and a gas generating agent 511. The types of the gas generator 51 include but are not limited to explosives, solid sodium azide, etc. The igniter is connected to the collision sensor 70. After receiving the signal from the collision sensor 70, the igniter ignites the gas generating agent 511, and the gas generating agent 511 generates gas or pressure to push the valve 53 and the propulsion link 60 in the piston cylinder 52 to move in the direction of extending out of the piston cylinder 52, thereby driving the sliding member 20 connected to the propulsion link 60 to move.

[0055] On the other hand, the present application provides a vehicle, which includes the seat assembly 1 in any of the above embodiments. The seat assembly 1 in this embodiment is the seat assembly 1 described in the above embodiments, and will not be elaborated here one by one. The seat assembly 1 is arranged inside the vehicle. When the vehicle collides, the gas generator 51 operates to push the sliding member 20 to move along the fixed rod 311, thereby pushing the seat 10 connected to the sliding member 20 to move backward, so as to increase the distance between the seat 10 and the vehicle head, obtain more crushing space for energy absorption, and protect the safety of the passengers to the greatest extent, reducing the possibility of the passengers being damaged by collision during the vehicle collision.

[0056] In one embodiment, the vehicle further includes an electronic control unit (not shown in the figure). The electronic control unit is connected to the gas generator 51, and the connection manners include but are not limited to signal connection, wire harness connection, etc. After the gas generator 51 receives the signal from the electronic control unit, the gas generator 51 operates, and the gas generator 51 generates gas or pressure to push the valve 53 and the propulsion link 60 in the piston cylinder 52 in the direction of extending out of the piston cylinder 52. The sliding member 20 connected to the propulsion link 60 moves relative to the two fixed rods 311 under the push of the propulsion link 60. The limiting component 40 located between the fixed rod 311 and the sliding groove 21 is released after receiving the thrust, thereby driving the seat 10 connected to the sliding member 20 to move backward.

[0057] In another embodiment, the gas generator 51 is connected to the collision sensor 70, and the collision sensor 70 is connected to the electronic control unit for transmitting a collision signal to the electronic control unit. The electronic control unit compares the received collision signal with a preset reference signal. When the collision degree reaches the preset reference, the electronic control unit sends a start signal to the gas generator 51. After the gas generator 51 receives the start signal sent by the electronic control unit, the gas generator 51 generates gas or pressure to push the valve 53 and the propulsion link 60 in the piston cylinder 52 in the direction of extending out of the piston cylinder 52. The sliding member 20 connected to the propulsion link 60 moves relative to the two fixed rods 311 under the push of the propulsion link 60. The limiting component 40 located between the fixed rod 311 and the sliding groove 21 is released after receiving the thrust, thereby driving the seat 10 connected to the sliding member 20 to move backward.

[0058] By providing the electronic control unit, the driving safety of the vehicle can be effectively improved, and when the vehicle collides, it can quickly react to move the seat 10 backward, reducing the collision damage to the passengers.
