[0049] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0050] The following is for reference. Figures 1-12 Describes a seat assembly 100 according to an embodiment of the present utility model.

[0051] like Figures 1-3 As shown, the seat assembly 100 according to an embodiment of the present invention includes: a seat frame 1, the seat frame 1 including a seat cushion frame 11; a flipping drive mechanism 2, the flipping drive mechanism 2 including: a medium pressure drive member 21, one end of the medium pressure drive member 21 is adapted to be rotatably connected to the vehicle body, and the other end of the medium pressure drive member 21 is rotatably connected to the seat frame 1, the medium pressure drive member 21 is used to drive the seat cushion frame 1 to flip towards the front of the vehicle; a ground lock mechanism 3, the ground lock mechanism 3 is adapted to be installed on the vehicle body, the ground lock mechanism 3 has an unlocked state and a locked state, in the locked state the ground lock mechanism 3 fixes the seat cushion frame 11 to the vehicle body, in the unlocked state the ground lock mechanism 3 unlocks the seat cushion frame 11 so that the flipping drive mechanism 2 can drive the seat cushion frame 11 to flip towards the front of the vehicle.

[0052] The seat assembly 100 includes a seat frame 1, a tilting drive mechanism 2, and a floor lock mechanism 3. The seat frame 1 includes a seat cushion frame 11 disposed within the seat cushion and a backrest frame 12 disposed within the backrest, and the seat cushion frame 11 and the backrest frame 12 are rotatably connected. Along the extending direction of the medium pressure drive member 21, the medium pressure drive member 21 has two opposing ends, and one end of the medium pressure drive member 21 is rotatably connected to the vehicle body. As some embodiments of this application, one end of the medium pressure drive member 21 may be rotatably connected to the vehicle body by, but is not limited to, a pivot connection, hinge, or other means.

[0053] The other end of the medium pressure drive member 21 is rotatably connected to the seat cushion frame 11. As some embodiments of this application, the other end of the medium pressure drive member 21 and the seat cushion frame 11 can be rotatably connected by means of, but not limited to, a pivot connection, a hinge, etc., so that the two ends of the medium pressure drive member 21 can rotate relative to the vehicle body and the seat cushion frame 11 respectively, so that the flipping drive mechanism 2 can drive the seat cushion frame 11 to flip towards the front of the vehicle, thereby driving the seat frame 1 to flip as a whole to increase the space for taking out and putting in the spare tire, thereby improving the convenience and efficiency of taking out and putting in the spare tire.

[0054] The ground lock mechanism 3 can be fixed to the vehicle body by means of bolts, rivets, etc. The ground lock mechanism 3 has an unlocked state and a locked state. When the ground lock mechanism 3 is in the locked state, the ground lock mechanism 3 and the flip drive mechanism 2 together fix the seat cushion frame 11 to the vehicle body to improve the strength of the seat cushion frame 11 and the stability of the seat assembly 100. When the ground lock mechanism 3 is in the unlocked state, the ground lock mechanism 3 unlocks the seat cushion frame 11, and the flip drive mechanism 2 can drive the seat cushion frame 11 to flip towards the front of the vehicle. There is no need for manual folding during the flipping process, which helps to improve the convenience and stability of the flipping process of the seat cushion frame 11. The automatic flipping of the seat cushion frame 11 towards the front of the vehicle drives the entire seat frame 1 to automatically flip towards the front of the vehicle, thereby increasing the operating space for taking out and placing the spare tire, which helps to improve the convenience and efficiency of taking out and placing the spare tire.

[0055] Specifically, when the local locking mechanism 3 is in the locked state, along the length direction of the vehicle (i.e. Figure 1 (As shown in the X direction), the ground lock mechanism 3 fixes the end of the seat frame 11 near the rear of the vehicle to the vehicle body, and the end of the seat frame 11 near the front of the vehicle is fixed to the vehicle body through the flip drive mechanism 2, so that the ground lock mechanism 3 and the flip drive mechanism 2 together fix the seat frame 11 to the vehicle body, realizing the fixation along the length direction of the vehicle (i.e., along the X direction). Figure 1 (As shown in the X direction), both ends of the seat cushion frame 11 are fixed to the vehicle body, thereby improving the strength of the seat cushion frame 11 and the stability of the seat assembly 100 when locked.

[0056] When the ground lock mechanism 3 is in the unlocked state, the ground lock mechanism 3 unlocks the seat cushion frame 11. The medium pressure drive member 21 extends and its two ends rotate relative to the vehicle body and the seat cushion frame 11 respectively, so as to drive the seat cushion frame 11 to automatically flip towards the front of the vehicle. There is no need for manual folding during the flipping process, which helps to improve the convenience and stability of the flipping process of the seat cushion frame 11. The automatic flipping of the seat cushion frame 11 towards the front of the vehicle can drive the entire seat frame 1 to automatically flip towards the front of the vehicle, thereby increasing the operating space for taking out and putting in the spare tire, improving the convenience and efficiency of taking out and putting in the spare tire. Moreover, after flipping into place, there is no need to hold it (e.g., flipping 45 degrees), which greatly improves the user's driving experience.

[0057] Therefore, by setting up a ground lock mechanism 3 and a flip drive mechanism 2, when the ground lock mechanism 3 is in the locked state, the seat frame 1 is fixed by the ground lock mechanism 3 and the flip drive mechanism 2 to improve the strength of the seat frame 1 and the stability of the seat assembly 100. When the ground lock mechanism 3 is in the unlocked state, the medium pressure drive component 21 automatically drives the seat cushion frame 11 to flip towards the front of the vehicle, which helps to increase the space for retrieving and placing the spare tire, improves the convenience and efficiency of retrieving and placing the spare tire, and eliminates the need for manual folding, which helps to improve the convenience of flipping the seat cushion frame 11 and the stability of the flipping process.

[0058] In some examples of this utility model, such as Figures 1-3 As shown, there are multiple tilting drive mechanisms 2, which are arranged along the width direction of the vehicle; and / or, there are multiple ground lock mechanisms 3, which are arranged along the width direction of the vehicle.

[0059] In some embodiments of this application, there are multiple tilting drive mechanisms 2, which are arranged along the width direction of the vehicle (i.e., ...). Figure 3 Arranged in the Y direction (as shown). As some embodiments of this application, there are multiple ground lock mechanisms 3, with the multiple ground lock mechanisms 3 arranged along the width direction of the vehicle (i.e., in the Y direction). Figure 3 Arranged in the Y direction (as shown). As some embodiments of this application, there are multiple tilting drive mechanisms 2 and multiple ground lock mechanisms 3, all arranged along the width direction of the vehicle (i.e., along the Y direction). Figure 3 Arranged in the Y direction as shown.

[0060] The tilting drive mechanism 2 can be configured as two, three, or more. This application uses two tilting drive mechanisms 2 as an example for illustration. The two tilting drive mechanisms 2 are located along the width direction of the vehicle (i.e., Figure 3 The arrangement is shown in the Y direction, and further, along the width direction of the vehicle (i.e., Figure 3 As shown in the Y direction, the two flip drive mechanisms 2 are respectively set close to both ends of the seat cushion frame 11, which helps to improve the balance of the seat cushion frame 11 and also reduces the risk of increased cost of the seat assembly 100 due to too many flip drive mechanisms 2, thus facilitating the low-cost and lightweight design of the vehicle.

[0061] The ground lock mechanism 3 can be configured as two, three, or more. This application uses two ground lock mechanisms 3 as an example for illustration. The two ground lock mechanisms 3 are located along the width direction of the vehicle (i.e., Figure 3 The arrangement is shown in the Y direction, and further, along the width direction of the vehicle (i.e., Figure 3As shown in the Y direction, the two ground lock mechanisms 3 are respectively set close to both ends of the seat cushion frame 11, which helps to improve the balance of the seat cushion frame 11 and can also reduce the risk of increased cost of the seat assembly 100 due to too many ground lock mechanisms 3, which further benefits the low-cost and lightweight design of the vehicle.

[0062] In some examples of this utility model, such as Figures 1-5 As shown, the tilting drive mechanism 2 also includes a fixed plate 22, which is adapted to be connected to the vehicle body, and one end of the medium pressure drive member 21 is rotatably connected to the fixed plate 22.

[0063] The fixing plate 22 is connected to the vehicle body, for example, by means of bolts, welding, etc. One end of the medium pressure drive component 21 is rotatably connected to the fixing plate 22, so that the medium pressure drive component 21 can be indirectly connected to the vehicle body through the fixing plate 22. Compared with the medium pressure drive component 21 being directly rotatably connected to the vehicle body, the indirect connection of the medium pressure drive component 21 to the vehicle body through the fixing plate 22 can improve the reliability of the connection position, reduce the risk of cracking of the vehicle body or the medium pressure drive component 21, thereby improving the operational reliability of the seat assembly 100.

[0064] In some examples of this utility model, such as Figure 2 , Figure 4 and Figure 6 As shown, the fixing plate 22 includes a pivot hole 221, and the seat frame 1 has a pivot shaft 14, which pivotally engages with the pivot hole 221.

[0065] The fixing plate 22 may have a pivot hole 221, and the seat frame 1 has a pivot shaft 14. The size and shape of the pivot shaft 14 are adapted to the size and shape of the pivot hole 221 so that the pivot shaft 14 and the pivot hole 221 can pivotally engage, thereby achieving the effect of rotatably connecting the seat frame 1 and the pivot shaft 14. When the medium pressure driving member 21 drives the seat frame 1 to rotate towards the front of the vehicle, the seat frame 1 can rotate towards the front of the vehicle with the axis of rotation of the pivot shaft 14 as the axis of rotation, which helps to improve the stability of the seat frame 1 during the flipping process.

[0066] In some examples of this utility model, such as Figure 1 As shown, along the length of the vehicle, the fixing plate 22 is located at the front end of the seat cushion frame 11. Along the length of the vehicle, the ground lock mechanism 3 is located at the rear end of the seat cushion frame 11.

[0067] In some embodiments of this application, along the length direction of the vehicle (i.e. Figure 1(As shown in the X direction), the fixing plate 22 is located at the front end of the seat cushion frame 11 and the ground lock mechanism 3 is located at the rear end of the seat cushion frame 11. This arrangement allows the fixing plate 22 and the ground lock mechanism 3 to be positioned reasonably, which is conducive to the even distribution of the fixing plate 22 and the ground lock mechanism 3 near the four corners of the seat cushion frame 11, thereby improving the stability of the seat cushion frame 11 when the ground lock mechanism 3 is in the locked state.

[0068] In some examples of this utility model, such as Figure 2 and Figure 5 As shown, the medium pressure driving component 21 may include: a first driving rod 211 and a second driving rod 212. The end of the first driving rod 211 away from the second driving rod 212 is adapted to be rotatably connected to the vehicle body. The end of the second driving rod 212 away from the first driving rod 211 is rotatably connected to the seat frame 1. The first driving rod 211 and the second driving rod 212 together define a medium cavity, which stores a medium. The medium can drive the first driving rod 211 and the second driving rod 212 to move away from each other.

[0069] Wherein, the end of the first drive rod 211 away from the second drive rod 212 is adapted to be rotatably connected to the vehicle body. As some embodiments of this application, the end of the first drive rod 211 away from the second drive rod 212 can be rotatably connected to the fixing plate 22, so that the end of the first drive rod 211 away from the second drive rod 212 is rotatably connected to the vehicle body.

[0070] The end of the second drive rod 212 away from the first drive rod 211 is rotatably connected to the seat frame 1. In some embodiments of this application, the end of the second drive rod 212 away from the first drive rod 211 is directly rotatably connected to the seat frame 1. In some embodiments of this application, the end of the second drive rod 212 away from the first drive rod 211 can be rotatably connected to the first connecting bracket 5 described below, so that the second drive rod 212 is rotatably connected to the seat frame 1.

[0071] The first drive rod 211 and the second drive rod 212 together define a medium cavity, which stores a medium, including but not limited to hydraulic oil and compressed gas. This medium drives the first drive rod 211 and the second drive rod 212 to move relatively away from each other. When the ground lock mechanism 3 unlocks, the medium drives the first drive rod 211 and the second drive rod 212 to move relatively away from each other, causing the medium-pressure drive member 21 to extend and automatically rotate the seat cushion frame 11 towards the front of the vehicle. This configuration makes the structure of the medium-pressure drive member 21 reasonable and reliable, and can stably drive the seat cushion frame 11 to automatically rotate towards the front of the vehicle, increasing the space for retrieving and placing the spare tire.

[0072] In some examples of this utility model, such as Figure 5 As shown, the medium is hydraulic oil or compressed gas.

[0073] In some embodiments of this application, the medium can be constructed as hydraulic oil. In some embodiments of this application, the medium can be constructed as compressed gas, which can be an inert gas. By constructing the medium as hydraulic oil or compressed gas, when the ground lock mechanism 3 unlocks, the medium can stably, reliably, and smoothly drive the first drive rod 211 and the second drive rod 212 to move away from each other, thereby improving the stability and smoothness of the seat frame 11 during the flipping process.

[0074] In some examples of this utility model, such as Figure 3 As shown, there are multiple tilting drive mechanisms 2, which are arranged along the width direction of the vehicle.

[0075] There can be multiple tilting drive mechanisms 2, for example, there can be two, three or more tilting drive mechanisms 2. By setting multiple tilting drive mechanisms 2, and the multiple tilting drive mechanisms 2 are along the width direction of the vehicle (i.e., Figure 3 The arrangement (as shown in the Y direction) allows multiple flip drive mechanisms 2 to exert their driving effect evenly, reducing the risk of damage or even breakage of the flip drive mechanism 2 caused by one flip drive mechanism 2 driving the entire seat cushion frame 11. In addition, it can also improve the stability of the flip, which is conducive to improving the safety and reliability of the seat assembly 100.

[0076] In some examples of this utility model, such as Figure 3 As shown, the seat frame 1 may also include: multiple backrest frames 12, and the seat cushion frame 11 includes: multiple seat cushion frames 111. The multiple seat cushion frames 111 are arranged and connected along the width direction of the vehicle. The multiple backrest frames 12 correspond one-to-one with the multiple seat cushion frames 111, and the backrest frames 12 are rotatably mounted on the corresponding seat cushion frames 111.

[0077] The seat cushion frame 11 may include multiple seat cushion frames 111, for example, there may be two or three seat cushion frames 111, and the multiple seat cushion frames 111 are arranged along the width direction of the vehicle (i.e., Figure 3 The seat cushion frames 111 are arranged in the Y direction as shown and connected together. The number of backrest frames 12 and seat cushion frames 111 is equal, and there is a one-to-one correspondence between them; that is, one backrest frame 12 corresponds to one seat cushion frame 111. The backrest frame 12 is rotatably mounted on the corresponding seat cushion frame 111. When the flip drive mechanism 2 needs to drive the seat cushion frame 11 to flip, the backrest frame 12 can be rotated first to fold the backrest frame 12 and the corresponding seat cushion frame 111, reducing the risk of interference between the backrest frame 12 and the front seat back when the flip drive mechanism 2 drives the seat cushion frame 11 to flip, thereby improving the reliability of the seat assembly 100.

[0078] In some examples of this utility model, such as Figure 3 As shown, the seat cushion frame 11 may also include a connecting beam 13, which is connected to multiple seat cushion frames 111.

[0079] Among them, the connecting beam 13 is along the width direction of the vehicle (i.e., Figure 3 The beam 13 extends in the Y direction as shown, so that the connecting beam 13 is connected to multiple seat cushion frames 111. By setting the connecting beam 13, the structural strength of multiple seat cushion frames 111 can be improved, and the risk of seat cushion frames 11 bending or even cracking under force when the low-flip drive mechanism 2 drives the seat cushion frames 11 to flip can be reduced, thereby improving the safety and reliability of the seat cushion frames 11.

[0080] In some examples of this utility model, such as Figure 3 As shown, the seat assembly 100 may also include: a seat belt buckle mounting bracket 4, and a seat belt buckle mounting bracket 4 connecting each pair of adjacent seat cushion frames 111.

[0081] The seat belt buckle mounting bracket 4 provides an assembly position for the seat belt buckle. Among the multiple seat cushion frames 111, a seat belt buckle mounting bracket 4 is connected between each two adjacent seat cushion frames 111 so that a seat belt buckle can be installed between each two adjacent seat cushion frames 111, thereby allowing any passenger in the row to fasten their seat belt and improving passenger safety.

[0082] In some examples of this utility model, such as Figure 1 , Figure 2 and Figure 7 As shown, the seat assembly 100 may further include: a first connecting bracket 5; among the plurality of seat cushion frames 111, the outermost seat cushion frame 111 is connected to the first connecting bracket 5 on the side away from the other seat cushion frames 111; among the plurality of backrest frames 12, the outermost backrest frame 12 is rotatably connected to the corresponding first connecting bracket 5 on the side away from the other backrest frames 12; the first connecting bracket 5 has a mounting groove 51 recessed toward the seat cushion frame 11; there are two floor lock mechanisms 3, and the two floor lock mechanisms 3 correspond one-to-one with the two first connecting brackets 5; the mounting groove 51 is used to accommodate part of the structure of the corresponding floor lock mechanism 3.

[0083] Among them, along the width direction of the vehicle (i.e. Figure 3 Among the multiple seat cushion frames 111 arranged in the Y direction (as shown), the two outermost seat cushion frames 111 are connected to a first connecting bracket 5 on the side away from the other seat cushion frames 111, along the width direction of the vehicle (i.e., Figure 3Among the multiple backrest frames 12 arranged in the Y direction shown, the two outermost backrest frames 12 are rotatably connected to the corresponding first connecting bracket 5 on the side away from the other backrest frames 12. This arrangement makes the connection between the first connecting bracket 5 and the backrest frame 12 reasonable, which is beneficial for the two outermost backrest frames 12 to be rotatably set on the seat cushion frame 11. This helps to reduce the risk of interference between the backrest frame 12 and the front seat back when the flip drive mechanism 2 drives the seat cushion frame 11 to flip, thereby reducing the driving difficulty of the flip drive mechanism 2 to drive the seat cushion frame 11 to flip.

[0084] The first connecting bracket 5 has a mounting groove 51, which is recessed into the seat frame 11. There are two ground lock mechanisms 3, and each ground lock mechanism 3 corresponds to one of the two first connecting brackets 5. That is, one ground lock mechanism 3 corresponds to one first connecting bracket 5. The mounting groove 51 is used to accommodate part of the structure of the corresponding ground lock mechanism 3, so as to reduce the space occupied by the ground lock mechanism 3 in the vehicle interior and improve the layout precision of the seat assembly 100.

[0085] In some examples of this utility model, such as Figure 3 and Figure 8 As shown, the seat assembly 100 may further include: a second connecting bracket 6; among the plurality of seat cushion frames 111, the outermost seat cushion frame 111 is connected to the side of the other seat cushion frames 111 and both sides of the other seat cushion frames 111 by the second connecting bracket 6; among the plurality of backrest frames 12, the outermost backrest frame 12 is rotatably connected to the side of the other backrest frames 12 and both sides of the other backrest frames 12 by the corresponding second connecting bracket 6.

[0086] Among the multiple seat cushion frames 111, the outermost seat cushion frame 111 is connected to a second connecting bracket 6 on the side closest to the other seat cushion frames 111, and both sides of the remaining seat cushion frames 111 (excluding the outermost seat cushion frame 111) are connected to the second connecting bracket 6. Among the multiple backrest frames 12, the outermost backrest frame 12 is rotatably connected to the corresponding second connecting bracket 6 on the side closest to the other backrest frames 12, and both sides of the remaining backrest frames 12 (excluding the outermost backrest frame 12) are rotatably connected to the corresponding second connecting bracket 6. This arrangement allows any one of the seat cushion frames 111 to be rotatably connected along the width direction of the vehicle (i.e., Figure 3 Both sides of the backrest frame 12 (in the Y direction shown) are provided with a first connecting bracket 5 or a second connecting bracket 6, so that any backrest frame 12 can be rotatably connected to the corresponding seat cushion frame 111, which is conducive to the smooth flipping of each backrest frame 12.

[0087] In some examples of this utility model, such as Figures 9-12As shown, the ground lock mechanism 3 may include: a ground lock body 31 and a ground lock bracket 32. The ground lock bracket 32 ​​is adapted to be installed on the vehicle body. The ground lock body 31 is connected to the seat cushion frame 11. The ground lock body 31 can lock with the ground lock bracket 32 ​​to fix the seat cushion frame 11 to the vehicle body. The ground lock body 31 can be separated from the ground lock bracket 32 ​​to unlock the seat cushion frame 11.

[0088] The ground lock bracket 32 ​​can be fixed to the vehicle body by means of bolts, riveting, etc. The ground lock body 31 and the seat frame 11 can be connected by means of welding, bolts, etc. The ground lock body 31 can lock and cooperate with the ground lock bracket 32 ​​to fix the seat frame 11 to the vehicle body, and the ground lock body 31 can be separated from the ground lock bracket 32 ​​to unlock the seat frame 11, thereby achieving the effect of locking or unlocking the seat frame 11.

[0089] When the ground lock body 31 and the ground lock bracket 32 ​​are locked together, along the length of the vehicle (i.e. Figure 1 (As shown in the X direction), the ground lock body 31 fixes the end of the seat frame 11 near the rear of the vehicle to the vehicle body via the ground lock bracket 32, and the end of the seat frame 11 near the front of the vehicle to the vehicle body via the flip drive mechanism 2, so that the ground lock mechanism 3 and the flip drive mechanism 2 together fix the seat frame 11 to the vehicle body, realizing the fixation along the length direction of the vehicle (i.e., along the X direction). Figure 1 (As shown in the X direction), both ends of the seat cushion frame 11 are fixed to the vehicle body, thereby improving the strength of the seat cushion frame 11 and the stability of the seat assembly 100 when locked.

[0090] When the ground lock body 31 is separated from the ground lock bracket 32, the medium pressure driving component 21 drives the seat cushion frame 11 and the ground lock body 31 to automatically flip towards the front of the vehicle. No manual folding is required during the flipping process, which helps to improve the convenience and stability of the flipping process of the seat cushion frame 11. The automatic flipping of the seat cushion frame 11 towards the front of the vehicle can drive the ground lock body 31 and the seat frame 1 to automatically flip towards the front of the vehicle, thereby increasing the operating space for taking out and putting in the spare tire, and improving the convenience and efficiency of taking out and putting in the spare tire.

[0091] In some examples of this utility model, such as Figures 9-12 As shown, the ground lock bracket 32 ​​may include: a bracket body 321 and a locking rod 322. The bracket body 321 is suitable for being installed on the vehicle body, and the locking rod 322 is installed on the bracket body 321. The ground lock body 31 can be locked or separated from the locking rod 322.

[0092] The bracket body 321 can be fixed to the vehicle body by means of bolts, riveting, etc., and the locking rod 322 is provided on the bracket body 321. Furthermore, the locking rod 322 can pass through the bracket body 321 and be fixedly connected to the bracket body 321. The floor lock body 31 can lock or disengage with the locking rod 322. When the floor lock body 31 is locked with the locking rod 322, the floor lock body 31 is locked with the floor lock bracket 32. When the floor lock body 31 is disengaged from the locking rod 322, the floor lock body 31 is disengaged from the floor lock bracket 32, thereby achieving the effect of locking or unlocking the seat cushion frame 11.

[0093] In some examples of this utility model, such as Figures 9-12 As shown, the lock body 31 may include: a lock plate 311, a first rotating member 312, a second rotating member 313, and an unlocking drive. The first rotating member 312 and the second rotating member 313 are rotatably disposed on the lock plate 311. The unlocking drive is connected between the lock plate 311 and the second rotating member 313. The unlocking drive can drive the second rotating member 313 to rotate so that the second rotating member 313 is separated from the locking rod 322. The first rotating member 312 can cooperate with the second rotating member 313 to limit the second rotating member 313 to the position locked with the locking rod 322. Driving the first rotating member 312 to rotate can release the limitation on the second rotating member 313.

[0094] In some embodiments of this application, the locking plate 311 may be fixed to the seat cushion frame 11 by means of welding, screwing, etc. In some embodiments of this application, the locking plate 311 may be constructed as part of the seat cushion frame 11. The first rotating member 312 and the second rotating member 313 are rotatably disposed on the locking plate 311. An unlocking drive member is connected between the locking plate 311 and the second rotating member 313, so that the unlocking drive member can drive the second rotating member 313 to rotate, thereby separating the second rotating member 313 from the locking rod 322, and further separating the floor lock body 31 from the floor lock bracket 32 ​​to achieve the effect of unlocking the seat cushion frame 11.

[0095] The first rotating member 312 can cooperate with the second rotating member 313. Furthermore, the first rotating member 312 can abut against the second rotating member 313 to limit the second rotating member 313 to a position locked with the locking rod 322. Driving the first rotating member 312 to rotate can prevent the first rotating member 312 from abutting against the second rotating member 313, thereby releasing the limitation on the second rotating member 313, so that the second rotating member 313 rotates to a position separated from the locking rod 322, thereby separating the floor lock body 31 from the floor lock bracket 32 ​​to achieve the effect of unlocking the seat frame 11.

[0096] In some examples of this utility model, such as Figure 12As shown, the second rotating member 313 has a locking tongue 3131. In the locked state, the locking tongue 3131 is located below the locking rod 322 and is locked in place with the locking rod 322. In the unlocked state, the locking tongue 3131 is separated from the locking rod 322.

[0097] In the locked state, along the height direction of the vehicle (i.e. Figure 1 (As shown in the Z direction), the locking tongue 3131 is located below the locking rod 322 and abuts against the locking rod 322, so that the locking rod 322 restricts the second rotating member 313 from rotating towards the front of the vehicle, thereby achieving the locking effect of the locking tongue 3131 and the locking rod 322. In the unlocked state, the locking tongue 3131 can rotate with the second rotating member 313 to separate the locking tongue 3131 from the locking rod 322. The locking rod 322 no longer restricts the second rotating member 313 from rotating with the seat frame 11 towards the front of the vehicle, thereby achieving the effect of locking or unlocking the seat frame 11.

[0098] In some examples of this utility model, such as Figure 12 As shown, the second rotating member 313 has a first mating part 3132 and a second mating part 3133. The first mating part 3132 and the second mating part 3133 together define a mating space. The first rotating member 312 has a first limiting part 3121. In the locked state, at least a portion of the first limiting part 3121 is located in the mating space and is mated with both the first mating part 3132 and the second mating part 3133 to limit the second rotating member 313. In the unlocked state, the first limiting part 3121 disengages from the mating space.

[0099] The second rotating member 313 has a first mating portion 3132 and a second mating portion 3133. In some embodiments of this application, the first mating portion 3132 and the second mating portion 3133 are integrally formed. In some embodiments of this application, the first mating portion 3132 and the second mating portion 3133 are welded together. The first mating portion 3132 and the second mating portion 3133 together define a mating space. A portion of the first rotating member 312 can be selectively disposed in the mating space so that the first rotating member 312 can limit the second rotating member 313 to a position locked with the locking rod 322, or release the limitation on the second rotating member 313.

[0100] The first rotating member 312 has a first limiting part 3121. In the locked state, at least a portion of the first limiting part 3121 is located in the mating space and is mated with both the first mating part 3132 and the second mating part 3133, so that the first rotating member 312 can limit the second rotating member 313 to a position that is locked and mated with the locking rod 322, thereby limiting the second rotating member 313 so that the locking tongue 3131 is always located below the locking rod 322 and abuts against the locking rod 322, thereby restricting the second rotating member 313 from rotating towards the front of the vehicle, so as to achieve the effect of locking the seat frame 11.

[0101] When unlocked, the first limiting part 3121 disengages from the mating space, thereby disengaging the first limiting part 3121 from the first mating part 3132 and the second mating part 3133. This causes the second rotating member 313 to rotate to the position where the locking tongue 3131 separates from the locking rod 322. The locking rod 322 no longer restricts the second rotating member 313 from rotating with the seat frame 11 toward the front of the vehicle, thus achieving the effect of unlocking the seat frame 11.

[0102] In some examples of this utility model, such as Figure 12 As shown, the outlines of the first mating part 3132, the second mating part 3133, and the first limiting part 3121 are all curved surfaces.

[0103] The contours of the first mating part 3132, the second mating part 3133, and the first limiting part 3121 can all be constructed as arc surfaces, so that the first mating part 3132 and the first limiting part 3121, and the second mating part 3133 and the first limiting part 3121 can guide each other to move, reducing the risk that the first limiting part 3121 will get stuck due to the sharp corners of the contours of the first mating part 3132, the second mating part 3133, and the first limiting part 3121, thereby achieving the effect of the first limiting part 3121 smoothly releasing the second rotating member 313.

[0104] In some examples of this utility model, such as Figure 12 As shown, the second rotating member 313 has a second limiting part 3134, which can cooperate with the bracket body 321 to limit the stroke of the second rotating member 313.

[0105] The second limiting part 3134 can cooperate with the bracket body 321. For example, when the second limiting part 3134 rotates to a certain position, it can abut against the bracket body 321 to limit the stroke of the second rotating member 313. This setting can reduce the risk of excessive rotation of the second rotating member 313 and help improve the reliability of the use of the lock body 31.

[0106] In some examples of this utility model, such as Figures 9-12As shown, the ground lock mechanism 3 may include: a pull cable 33, which is connected to the first rotating member 312 and has a partial structure adapted to be located in the trunk of the vehicle. The pull cable 33 is used to drive the first rotating member 312 to rotate in order to release the restriction on the second rotating member 313.

[0107] In some embodiments of this application, the pull cable 33 can be constructed of copper wire. In other embodiments, the pull cable 33 can be constructed of iron wire. The pull cable 33 is connected to the first rotating member 312, allowing the occupant to pull the pull cable 33 to drive the first rotating member 312 to rotate, thereby releasing the first rotating member 312 from its limiting position on the second rotating member 313. Part of the pull cable 33 can be located in the vehicle's trunk. This arrangement allows for a reasonable placement of the pull cable 33, facilitating occupant operation and thus enabling easier operation of the floor lock body 31, improving the user's driving experience.

[0108] Specifically, the pull cables 33 of multiple floor lock mechanisms 3 can be partially integrated into one cable and located in the trunk of the vehicle. This arrangement facilitates the simultaneous operation of multiple floor lock mechanisms 3 by the occupants to unlock the seat frame 11.

[0109] In some examples of this utility model, such as Figure 12 As shown, the ground lock body 31 also includes: a pull plate 315, which is connected to the first rotating member 312, and a pull wire 33 is connected to the pull plate 315.

[0110] The pull plate 315 can be disposed between the pull cable 33 and the first rotating member 312, so that the pull cable 33 can be indirectly connected to the first rotating member 312. The part of the pull plate 315 near the pull cable 33 can be cast integrally with the pull cable 33, and the part of the pull plate 315 near the first rotating member 312 can be rotatably connected to the first rotating member 312. Since other vehicle components are disposed around the first rotating member 312, by setting the pull plate 315 to connect the pull cable 33 and the first rotating member 312, the risk of the pull cable 33 breaking due to long-term friction with other vehicle components can be reduced, thereby improving the reliability of the pull cable 33 driving the first rotating member 312 to rotate, reducing the risk of the ground lock mechanism 3 failing to unlock due to the breakage of the pull cable 33, and thus improving the working reliability of the seat assembly 100.

[0111] In some examples of this utility model, such as Figures 10-11 As shown, the locking plate 311 may include: a first locking plate 3111 and a second locking plate 3112. The first locking plate 3111 and the second locking plate 3112 are connected and together define the installation space. At least a portion of the structure of the first rotating member 312, at least a portion of the structure of the second rotating member 313, and at least a portion of the structure of the unlocking drive member are all located in the installation space.

[0112] In some embodiments of this application, the first locking plate 3111 and the second locking plate 3112 can be welded together. In some embodiments of this application, the first locking plate 3111 and the second locking plate 3112 can be bolted together. The first locking plate 3111 and the second locking plate 3112 can be recessed in directions away from each other, so that when the first locking plate 3111 and the second locking plate 3112 are connected, an installation space can be defined between the first locking plate 3111 and the second locking plate 3112.

[0113] At least a portion of the structure of the first rotating member 312, at least a portion of the structure of the second rotating member 313, and at least a portion of the structure of the unlocking drive are all located in the installation space to reduce the space occupied by the first rotating member 312, the second rotating member 313, and the unlocking drive, thereby improving the design precision of the seat assembly 100. Furthermore, by locating at least a portion of the structure of the first rotating member 312, at least a portion of the structure of the second rotating member 313, and at least a portion of the structure of the unlocking drive in the installation space, the first rotating member 312, the second rotating member 313, and the unlocking drive can stably perform locking and unlocking functions within the installation space, reducing the risk of interference between the first rotating member 312, the second rotating member 313, and the unlocking drive and other vehicle components outside the installation space, thereby reducing the risk of unlocking or locking failure of the seat cushion frame 11 and further improving the working stability of the seat assembly 100.

[0114] In some examples of this utility model, the unlocking drive (not shown in the figure) is constructed as an elastic unlocking member (not shown in the figure).

[0115] The unlocking drive component is constructed as an elastic unlocking component, such as a spring, torsion spring, or spring sheet. By setting the elastic unlocking component, when the occupant pulls the cable 33 to release the first rotating component 312 from its limit on the second rotating component 313, the elastic unlocking component can automatically drive the second rotating component 313 to rotate and unlock the seat cushion frame 11, thereby improving the ease of unlocking.

[0116] In some examples of this utility model, such as Figures 9-12 As shown, the lock body 31 may further include: a first connecting shaft 316 and a second connecting shaft 317. The first connecting shaft 316 and the second connecting shaft 317 are both inserted through the lock plate 311 and are both suitable for connection with the seat frame 11. The first rotating member 312 is rotatably disposed on the first connecting shaft 316, and the second rotating member 313 is rotatably disposed on the second connecting shaft 317.

[0117] In this embodiment, both the first connecting shaft 316 and the second connecting shaft 317 pass through the lock plate 311 and are connected to the seat cushion frame 11. In some embodiments of this application, the first connecting shaft 316 and the second connecting shaft 317 are connected to the seat cushion frame 11 by welding. In some embodiments of this application, the first connecting shaft 316 and the second connecting shaft 317 are connected to the seat cushion frame 11 by bolts. Further, both the first connecting shaft 316 and the second connecting shaft 317 pass through the lock plate 311 and the first connecting bracket 5 to connect the floor lock body 31 to the first connecting bracket 5, thereby connecting the floor lock body 31 to the seat cushion frame 11.

[0118] The first rotating member 312 is rotatably disposed on the first connecting shaft 316, and the second rotating member 313 is rotatably disposed on the second connecting shaft 317, so that the first connecting shaft 316 and the second connecting shaft 317 can guide the first rotating member 312 and the second rotating member 313 respectively. This facilitates the first rotating member 312 and the second rotating member 313 to rotate about the axes of the first connecting shaft 316 and the second connecting shaft 317 respectively, so that the first rotating member 312 and the second rotating member 313 can rotate accurately to unlock the seat cushion frame 11, thereby achieving the effect of unlocking the seat cushion frame 11.

[0119] In some examples of this utility model, such as Figure 11 As shown, the ground lock body 31 also includes a vibration damping member 318, which is disposed on the lock plate 311 and is adapted to contact the locking rod 322.

[0120] The damping element 318 may be, but is not limited to, made of rubber or felt. In some embodiments of this application, the damping element 318 may be directly fixed to the locking plate 311. In some embodiments of this application, the damping element 318 may be fixed to a connecting plate, which in turn is fixed to the locking plate 311, so that the damping element 318 can be indirectly fixed to the locking plate 311 via the connecting plate. It should be noted that the damping element 318 may have a protruding structure to facilitate demolding and positioning of the damping element 318.

[0121] By placing the damper 318 on the lock plate 311, when the seat cushion frame 11 is unlocked and flipped towards the front of the vehicle, the damper 318 separates from the locking rod 322. When the occupant controls the seat cushion frame 11 to return to its original position, the damper 318 contacts the locking rod 322, reducing the risk of damage to the locking rod 322 or the ground lock body 31 due to direct impact between the locking rod 322 and the ground lock body 31 when the seat cushion frame 11 returns to its original position. This reduces the risk of ground lock mechanism 3 locking failure and improves the reliability of the seat assembly 100.

[0122] In some examples of this utility model, such as Figure 10As shown, the bracket body 321 may include: a first support plate 3211, a second support plate 3212 and a third support plate 3213. The first support plate 3211 and the third support plate 3213 are spaced apart. A locking rod 322 passes through the first support plate 3211 and the third support plate 3213. The second support plate 3212 is connected between the first support plate 3211 and the third support plate 3213.

[0123] The first support plate 3211 and the third support plate 3213 are arranged opposite to each other and spaced apart. The second support plate 3212 is connected between the first support plate 3211 and the third support plate 3213. The second support plate 3212 can be connected to the vehicle body by means of, but not limited to, riveting or welding, so that the bracket body 321 is fixed to the vehicle body as a whole, thereby improving the positional stability of the bracket body 321. Part of the floor lock body 31 is located between the first support plate 3211 and the third support plate 3213. This arrangement makes the structural design of the bracket body 321 more reasonable and helps to improve the structural strength of the bracket body 321, thereby improving the stability of the seat assembly 100.

[0124] The locking rod 322 passes through the first support plate 3211 and the third support plate 3213 to ensure that the locking rod 322 is reliably and stably mounted on the bracket body 321, thereby reducing the risk of the locking rod 322 moving around and improving the reliability of the ground lock mechanism 3.

[0125] In some examples of this utility model, such as Figure 3 As shown, along the width direction of the vehicle, multiple ground lock mechanisms 3 are respectively disposed at both ends of the seat cushion frame 11. The seat assembly 100 may further include: a first connecting bracket 5. The seat frame 1 includes multiple seat cushion frames 111. Among the multiple seat cushion frames 111, the outermost seat cushion frame 111 is connected to the first connecting bracket 5 on the side away from the other seat cushion frames 111. The first connecting bracket 5 has a mounting groove 51 recessed toward the seat cushion frame 11. There are two ground lock mechanisms 3. At least a portion of the ground lock body 31 of the two ground lock mechanisms 3 is received in the corresponding mounting groove 51 and connected to the corresponding first connecting bracket 5.

[0126] Along the width of the vehicle, multiple floor lock mechanisms 3 are distributed at both ends of the seat cushion frame 11. This arrangement allows for a reasonable positioning of the floor lock mechanisms 3, ensuring that each of the multiple floor lock mechanisms 3 can perform a locking function at both ends of the seat cushion frame 11. Among the multiple seat cushion frames 111 arranged along the width of the vehicle, the two outermost seat cushion frames 111 are connected to a first connecting bracket 5 on the side away from the other seat cushion frames 111. Among the multiple backrest frames 12 arranged along the width of the vehicle, the two outermost backrest frames 12 are rotatably connected to the corresponding first connecting bracket 5 on the side away from the other backrest frames 12. This arrangement allows for a reasonable connection between the first connecting bracket 5 and the backrest frame 12, and allows the two outermost backrest frames 12 to be rotatably mounted on the seat cushion frame 11. This helps reduce the risk of interference between the backrest frame 12 and the front seat back when the flip drive mechanism 2 drives the seat cushion frame 11 to flip, thereby reducing the difficulty of driving the flip drive mechanism 2 to flip the seat cushion frame 11.

[0127] The first connecting bracket 5 has a mounting groove 51, which is recessed into the seat frame 11. There are two ground lock mechanisms 3, and each ground lock mechanism 3 corresponds to one of the two first connecting brackets 5. That is, one ground lock mechanism 3 corresponds to one first connecting bracket 5. At least part of the ground lock body 31 of the two ground lock mechanisms 3 is received in the corresponding mounting groove 51 and connected to the corresponding first connecting bracket 5. The mounting groove 51 is used to receive part of the structure of the corresponding ground lock mechanism 3, so as to reduce the space occupied by the ground lock mechanism 3 in the vehicle interior and improve the layout precision of the seat assembly 100.

[0128] In some examples of this utility model, such as Figure 11 As shown, the ground lock body 31 also includes: a vibration damping member 318, which is disposed on the lock plate 311 and located above the locking rod 322. The vibration damping member 318 has a receiving groove, and a portion of the locking rod 322 is located in the receiving groove; and / or, the unlocking drive member is constructed as an elastic unlocking member.

[0129] The damping element 318 may be, but is not limited to, made of rubber or felt. In some embodiments of this application, the damping element 318 may be directly fixed to the locking plate 311. In some embodiments of this application, the damping element 318 may be fixed to a connecting plate, which is fixed to the locking plate 311, so that the damping element 318 can be indirectly fixed to the locking plate 311 through the connecting plate. The damping element 318 is located above the locking rod 322. This arrangement allows for a reasonable positioning of the damping element 318. When the seat cushion frame 11 is unlocked and flipped towards the front of the vehicle, the damping element 318 separates from the locking rod 322. When the occupant controls the seat cushion frame 11 to reset, the damping element 318 contacts the locking rod 322, reducing the risk of damage to the locking rod 322 or the ground lock body 31 due to direct impact when the seat cushion frame 11 returns to its original position. This reduces the risk of locking failure of the ground lock mechanism 3 and improves the reliability of the seat assembly 100.

[0130] The damper 318 may have a receiving groove. In the locked state, the receiving groove is located at the lower part of the damper 318 and is recessed towards the inside of the damper 318. The inner wall of the receiving groove is curved and adapted to the locking rod 322. The receiving groove can provide a receiving position for the locking rod 322 so that a portion of the locking rod 322 can be located within the receiving groove. By providing the receiving groove, the contact area between the damper 318 and the locking rod 322 can be increased, thereby further improving the damping effect of the damper 318 on the locking rod 322.

[0131] The unlocking drive can be constructed as an elastic unlocking component, such as a spring, torsion spring, or spring sheet. By setting an elastic unlocking component, when the occupant pulls the cable 33 to release the first rotating component 312 from its limit on the second rotating component 313, the elastic unlocking component can automatically drive the second rotating component 313 to rotate and unlock the seat cushion frame 11, thereby improving the ease of unlocking.

[0132] The vehicle according to this utility model embodiment includes the seat assembly 100 of the vehicle described in the above embodiment. By providing a ground lock mechanism 3 and a flip drive mechanism 2, when the ground lock mechanism 3 is in the locked state, the seat frame 1 is fixed by the ground lock mechanism 3 and the flip drive mechanism 2 to improve the strength of the seat frame 1 and the stability of the seat assembly 100. When the ground lock mechanism 3 is in the unlocked state, the medium pressure drive component 21 automatically drives the seat cushion frame 11 to flip towards the front of the vehicle, which helps to increase the space for retrieving and placing the spare tire, improves the convenience and efficiency of retrieving and placing the spare tire, and eliminates the need for manual folding, which helps to improve the convenience of flipping the seat cushion frame 11 and the stability of the flipping process.
