[0023] The following is for reference. Figures 1-3 The seat frame assembly 100 according to an embodiment of the present utility model is simple in structure, can increase the space below the rear of the seat basin 5, facilitate the arrangement of other structures, and can restrict the occupants in the front and rear directions when a vehicle collision occurs, thereby improving riding safety.

[0024] like Figures 1-3 As shown, a seat frame assembly 100 according to an embodiment of the present invention includes: a seat frame 1, a front cross tube 3, and a seat basin 5.

[0025] The seat frame 1 includes two seat side plates 11 spaced laterally, with an anti-sag area 12 formed between the two seat side plates 11. The front end of the seat side plate 11 is provided with a first connecting bracket 2 extending forward. The two ends of the seat front cross tube 3 are connected to the first connecting bracket 2 of the two seat side plates 11, and the seat front cross tube 3 is located in front of the anti-sag area 12. The seat basin 5 is installed above the seat front cross tube 3 and the seat frame 1, and the rear part of the seat basin 5 is at least partially constructed to extend downward from front to back and is located within the anti-sag area 12.

[0026] Specifically, the seat cushion frame assembly 100 is disposed on the seat and located at the lower part of the seat. The seat cushion frame assembly 100 can be installed on the vehicle floor via a sliding device, thereby adjusting the position of the seat in the fore-and-aft direction of the vehicle to meet different seating needs and improve the seating experience. The seat cushion frame assembly 100 is provided with a seat cushion frame 1, which can support the entire seat cushion frame assembly 100 and define the installation space for installing the other structures of the seat cushion frame assembly 100. The seat cushion frame 1 is provided with two seat cushion side panels 11, which extend in the fore-and-aft direction and are spaced apart in the left-and-right direction on both sides of the seat cushion frame 1.

[0027] Furthermore, each of the two seat cushion side panels 11 has a first connecting bracket 2 at its front end. The first connecting bracket 2 extends forward and its front end is located in front of the front end of the seat cushion side panel 11. The two seat cushion side panels 11 define an anti-submersion area 12, thus the front end of the first connecting bracket 2 is located in front of the anti-submersion area 12. The seat cushion frame assembly 100 also has a front seat cushion tube 3, which extends in the left-right direction. The rear ends of both ends of the front seat cushion tube 3 are connected to the front ends of the two first connecting brackets 2, so that the front seat cushion tube 3 is located in front of the anti-submersion area 12, thereby expanding the space of the anti-submersion area 12 and facilitating the arrangement of other structures inside the seat cushion frame assembly 100.

[0028] Furthermore, the seat frame assembly 100 is also provided with a seat basin 5, which is installed above the front cross tube 3 and the seat frame 1. The occupant can sit on the seat basin 5. The front cross tube 3 can support the front of the seat basin 5, and the seat frame 1 can support the rear of the seat basin 5. The front cross tube 3 is located at the front end of the first connecting bracket 2, which can increase the size of the front cross tube 3 and the seat frame 1 in the front-rear direction, thereby increasing the area of ​​the seat basin 5 in the front-rear direction to improve the occupant's riding comfort. The rear of the seat basin 5 is at least partially constructed to extend downward from front to back and is located within the anti-submersion area 12. This means that the rear part of the seat basin 5 can be constructed to extend downward from front to back, or the entire rear of the seat basin 5 can be constructed to extend downward from front to back.

[0029] Thus, a downwardly recessed anti-submersion area 12 can be defined between the rear of the seat basin 5 and the seat frame 1, and the front of the seat basin 5 is higher than the anti-submersion area 12 in the horizontal direction. When the occupant sits on the seat frame assembly 100, he / she can place his / her buttocks on the anti-submersion area 12 and support his / her thighs on the seat basin 5. When the vehicle collides, the occupant will tend to move forward due to the impact force. The front of the seat basin 5 can limit the occupant's buttocks, reduce the displacement of the occupant in the collision, and thus avoid submersion, improve riding safety, and the structure is simple and can reduce the installation cost.

[0030] According to the seat frame assembly 100 of this utility model embodiment, the first connecting bracket 2 is configured to extend forward at the front end of the seat side plate 11, and the front horizontal tube 3 of the seat is connected to the front end of the first connecting bracket 2, so that the front horizontal tube 3 of the seat is located in front of the anti-subsidence area 12, thereby increasing the space under the rear of the seat basin 5, which facilitates the arrangement of other structures. The rear of the seat basin 5 is at least partially configured to extend downward from front to back and is located within the anti-subsidence area 12. In this way, the occupants can be restricted in the front-to-back direction when the vehicle is involved in a collision, so as to avoid subsidence and improve riding safety. The structure is simple, the effect is better, and the application range is wider.

[0031] In some embodiments, the first connecting bracket 2 is disposed on the inner side of the front end of the corresponding seat cushion side plate 11, and the front end of the first connecting bracket 2 protrudes forward from the front end of the seat cushion side plate 11, and the rear side of the front horizontal tube 3 of the seat cushion is connected to the front end of the first connecting bracket 2.

[0032] Specifically, the first connecting bracket 2 is installed at the front end of the seat cushion side plate 11, and as follows: Figure 1 and Figure 3 As shown, both seat cushion side panels 11 are provided with a first connecting bracket 2, and the first connecting bracket 2 is installed on the inner side of the front end of the seat cushion side panel 11. The first connecting bracket 2 can be connected to the seat cushion side panel 11 by means of connectors or welding. Setting the connection between the first connecting bracket 2 and the seat cushion side panel 11 on the inner side of the seat cushion side panel 11 can avoid collisions at the connection and ensure the reliability of the connection.

[0033] Furthermore, the front end of the first connecting bracket 2 extends forward and protrudes beyond the front end of the seat cushion side plate 11, thereby extending the size of the seat cushion frame 1 in the front-back direction. The rear side of the front horizontal tube 3 of the seat cushion is connected to the front end of the first connecting bracket 2, so that the front horizontal tube 3 of the seat cushion is located in front of the anti-submersion area 12, thereby extending the front end of the anti-submersion area 12, increasing the area of ​​the anti-submersion area 12, improving the anti-submersion effect, and increasing the size of the seat basin 5 in the front-back direction to improve riding comfort.

[0034] In some embodiments, the first connecting bracket 2 includes a bracket base plate 21 and two bracket side plates 22. The two bracket side plates 22 are distributed laterally at intervals. The two bracket side plates 22 are respectively connected to the bracket base plate 21 and define bracket grooves that open upwards. The front ends of the bracket base plate 21 and the bracket side plates 22 are fixedly connected to the front horizontal tube 3 of the seat cushion. At least one of the two bracket side plates 22 is connected to the side plate 11 of the seat cushion.

[0035] Specifically, the first connecting bracket 2 is installed on the inner front end of the seat cushion side plate 11, and as shown... Figure 3 As shown, the first connecting bracket 2 includes a bracket base plate 21 and a bracket side plate 22. There are two bracket side plates 22, which are spaced apart in the left and right direction. The bracket base plate 21 is connected between the lower ends of the two bracket side plates 22, so that the two bracket side plates 22 and the bracket base plate 21 can jointly define the bracket groove. The bracket groove is designed to be open upward, which can improve the structural strength of the first connecting bracket 2.

[0036] Furthermore, at least one of the two support side plates 22 is connected to the seat cushion side plate 11, and the first connecting bracket 2 is installed on the inner side of the seat cushion side plate 11. That is, the outer support side plate 22 of the two support side plates 22 can be connected to the inner side of the seat cushion side plate 11, increasing the connection area and ensuring connection reliability. Moreover, the front ends of the support base plate 21 and the support side plate 22 are fixedly connected to the front horizontal tube 3 of the seat cushion, which can increase the connection area with the front horizontal tube 3 of the seat cushion and ensure connection reliability.

[0037] Furthermore, the front horizontal tube 3 of the seat cushion can also be supported above the two bracket side plates 22, and an upwardly open limiting groove is provided on the two bracket side plates 22. At least part of the lower end of the front horizontal tube 3 of the seat cushion is placed in the limiting groove and is fixedly connected to the limiting groove, so as to improve the installation stability of the front horizontal tube 3 of the seat cushion.

[0038] In addition, when the seat frame 1 is subjected to force, the force can be transmitted to the front horizontal tube 3 of the seat through the two support side plates 22 and the support bottom plate 21 respectively, so as to increase the transmission path of the force, thereby weakening the effect of the force and ensuring the reliability of the front horizontal tube 3 of the seat.

[0039] In some embodiments, the seat frame assembly 100 further includes a second connecting bracket 4, which is sleeved on the front horizontal tube 3 of the seat, and the front part of the seat basin 5 is mounted and supported above the second connecting bracket 4.

[0040] Specifically, such as Figures 1-3As shown, the seat frame assembly 100 is also provided with a second connecting bracket 4. The second connecting bracket 4 is provided with a mounting hole, and the front horizontal tube 3 of the seat can be inserted into the mounting hole. That is, when the second connecting bracket 4 is installed on the front horizontal tube 3 of the seat, the second connecting bracket 4 is sleeved on the outside of the front horizontal tube 3 of the seat, and the second connecting bracket 4 can be limited in the circumferential direction by the front horizontal tube 3 of the seat, so as to ensure the reliability of the installation of the second connecting bracket 4.

[0041] The second connecting bracket 4 is designed to extend in the front-to-back direction, and the front part of the seat basin 5 is mounted and supported on the top of the second connecting bracket 4. This increases the connection area between the seat basin 5 and the front horizontal tube 3 of the seat cushion, thereby improving the installation reliability of the front part of the seat basin 5. In addition, the second connecting bracket 4 increases the support area for the front part of the seat basin 5, thereby dispersing the force on the front part of the seat basin 5 and ensuring the reliability of the seat basin 5 in use.

[0042] In addition, multiple second connecting brackets 4 can be provided. In this embodiment, two second connecting brackets 4 are provided. Multiple second connecting brackets 4 can be distributed axially along the front horizontal tube 3 of the seat cushion. Each second connecting bracket 4 can support the front of the seat basin 5, so that multiple parts of the front of the seat basin 5 can be installed and supported on the corresponding second connecting bracket 4. This ensures the reliability of the connection and disperses the force, thereby improving the structural strength of the front of the seat basin 5, extending the service life of the seat basin 5, and preventing the front of the seat basin 5 from deforming and causing the occupant to fall in the event of a collision, thus improving riding safety.

[0043] In some embodiments, the second connecting bracket 4 is provided with a first connecting portion 41, and the basin 5 is provided with a second connecting portion 513. The first connecting portion 41 and the second connecting portion 513 are detachably connected by a first connecting member 6.

[0044] Specifically, such as Figure 1 and Figure 3 As shown, the second connecting bracket 4 is provided with a first connecting part 41, which can be configured as a connecting hole, and the basin 5 is provided with a second connecting part 513, which can also be configured as a connecting hole. When the basin 5 is installed on the second connecting bracket 4, the first connecting member 6 can be sequentially inserted into the second connecting part 513 and the first connecting part 41 to fix the basin 5 and the second connecting bracket 4 together. The first connecting member 6 can be a bolt, etc. The structure is simple, the installation is convenient, and the installation cost is low.

[0045] In actual setup, the second connecting bracket 4 can be provided with multiple first connecting parts 41, and the basin 5 can be provided with multiple second connecting parts 513. The multiple first connecting parts 41 and multiple second connecting parts 513 are provided in a one-to-one correspondence, so that there are multiple connection points between the basin 5 and the second connecting bracket 4, and the force can be distributed to multiple connection points to weaken the effect of the force and improve the reliability of the connection.

[0046] In other embodiments, the seat cushion side plate 11 is provided with a third connecting part 111, and the seat basin 5 is provided with a fourth connecting part 521. The third connecting part 111 and the fourth connecting part 521 are detachably connected by a second connecting member 7.

[0047] Specifically, such as Figure 1 and Figure 3 As shown, the seat cushion side plate 11 is provided with a third connecting part 111, which can be configured as a connecting hole, and the seat basin 5 is provided with a fourth connecting part 521, which can also be configured as a connecting hole. When the seat basin 5 is installed on the seat cushion side plate 11, the second connecting member 7 can be sequentially inserted through the fourth connecting part 521 and the third connecting part 111 to fix the seat basin 5 and the seat cushion side plate 11 together. The second connecting member 7 can be a bolt, etc. The structure is simple, the installation is convenient, and the installation cost is low.

[0048] In actual installation, multiple third connecting parts 111 can be provided on the seat cushion side plate 11, and multiple fourth connecting parts 521 can be provided on the seat basin 5. The multiple third connecting parts 111 and multiple fourth connecting parts 521 are arranged one-to-one, so that there are multiple connection points between the seat basin 5 and the seat cushion side plate 11, and the force can be distributed to multiple connection points to weaken the effect of the force and improve the reliability of the connection.

[0049] In this way, the second connecting bracket 4 and the front part of the seat 5 are connected by the first connecting member 6, and the rear part of the seat 5 and the seat cushion side plate 11 are connected by the second connecting member 7, so that the seat 5 is detachable relative to the second connecting bracket 4 and the seat cushion side plate 11, and the seat 5 can be replaced when it is damaged, thus saving maintenance costs.

[0050] In some embodiments, the first connecting portion 41 and the second connecting portion 513 are each configured as at least two and cooperate in a one-to-one correspondence, wherein at least one first connecting portion 41 is located on the front side of the front cross tube 3 of the seat cushion and at least another first connecting portion 41 is located on the rear side of the front cross tube 3 of the seat cushion.

[0051] Specifically, such as Figure 1 and Figure 3 As shown, the second connecting bracket 4 is provided with a first connecting part 41, and the first connecting part 41 is provided with at least two, that is, the first connecting part 41 can be provided with two, three or four, etc. The basin 5 is provided with a second connecting part 513, and the second connecting part 513 is provided with at least two, that is, the second connecting part 513 can be provided with two, three or four, etc. The first connecting part 41 and the second connecting part 513 are provided in a one-to-one correspondence, so that there are at least two connection points between the basin 5 and the second connecting bracket 4, which can improve the reliability of the installation of the basin 5.

[0052] Furthermore, the second connecting bracket 4 is sleeved on the front horizontal tube 3 of the seat cushion, such that the front part of the second connecting bracket 4 is located on the front side of the front horizontal tube 3 of the seat cushion, and the rear part of the second connecting bracket 4 is located on the rear side of the front horizontal tube 3 of the seat cushion. At least one first connecting part 41 is disposed on the front part of the second connecting bracket 4, that is, at least one first connecting part 41 is located on the front side of the front horizontal tube 3 of the seat cushion, and at least one first connecting part 41 is disposed on the rear part of the second connecting bracket 4, that is, at least another first connecting part 41 is located on the rear side of the front horizontal tube 3 of the seat cushion. This makes at least two first connecting parts 41 distributed at intervals along the front-rear direction on the second connecting bracket 4, which can improve the connection reliability and limit the seat basin 5 in the front-rear direction, thereby improving the anti-submersion performance of the seat frame assembly 100.

[0053] In some embodiments, at least a portion of the sitz bath 5 is configured to protrude upward to form a connecting protrusion 511 and to form a downward-open connecting receiving groove 512 at the bottom of the connecting protrusion 511, with the top of the second connecting bracket 4 extending at least partially into the connecting receiving groove 512.

[0054] Specifically, such as Figure 1 As shown, the seat basin 5 is provided with a connecting protrusion 511. The connecting protrusion 511 is constructed to protrude upwards at the front of the seat basin 5, which can increase the structural strength of the front of the seat basin 5 and ensure the reliability of the seat basin 5 in use. Figure 2 As shown, the bottom end of the connecting protrusion 511 is open downwards, thereby forming a connecting receiving groove 512. The top of the second connecting bracket 4 extends at least partially into the connecting receiving groove 512, and the second connecting part 513 is disposed on the connecting protrusion 511, so that the first connecting part 41 of the second connecting bracket 4 can be connected to the second connecting part 513 in the connecting receiving groove 512 through the first connecting member 6, ensuring connection reliability.

[0055] In addition, the connecting receiving groove 512 is configured to extend in the front-to-back direction, and the shape of the top of the second connecting bracket 4 matches the connecting receiving groove 512. This allows the connecting receiving groove 512 to limit the second connecting bracket 4 after the top of the second connecting bracket 4 is placed in the connecting receiving groove 512, preventing the second connecting bracket 4 from shifting in the front-to-back direction, thereby improving the anti-submersion performance of the seat frame assembly 100.

[0056] In some embodiments, the seat 5 includes a front seat area 51 and a rear seat area 52 connected in a front-rear direction. The front seat area 51 is mounted above the front cross tube 3 of the seat cushion, and the rear seat area 52 is configured to extend downward from front to back and is located within the anti-submersion area 12.

[0057] Specifically, such as Figure 1As shown, the sitz bath 5 is provided with a front sitz bath area 51 and a rear sitz bath area 52. The front sitz bath area 51 is located at the front of the sitz bath 5, and the rear sitz bath area 52 is located at the rear of the sitz bath 5. The rear sitz bath area 52 is connected to the rear side of the front sitz bath area 51. The second connecting part 513 is provided in the front sitz bath area 51, so that the front sitz bath area 51 can be installed above the front horizontal tube 3 of the seat cushion through the second connecting bracket 4, which can improve the installation strength of the front sitz bath area 51 and ensure the reliability of use.

[0058] Furthermore, the rear seat area 52 is constructed to extend downwards from front to back, meaning that the end of the rear seat area 52 away from the front seat area 51 is located horizontally below the front seat area 51. This allows the rear seat area 52 to be located within the anti-submersion area 12. Thus, when the occupant sits on the seat 5, the occupant's buttocks can be placed in the rear seat area 52, and the front seat area 51 can limit the occupant's buttocks in the front-back direction, thereby improving anti-submersion performance and ensuring safety during use.

[0059] In some embodiments, a reinforcing protrusion 53 extending laterally is formed at the junction of the front seat region 51 and the rear seat region 52, and the reinforcing protrusion 53 protrudes upward from the front seat region 51 and the rear seat region 52.

[0060] Specifically, such as Figure 1 As shown, the sitz bath 5 also has a reinforcing protrusion 53. The reinforcing protrusion 53 is formed at the connection between the front sitz bath area 51 and the rear sitz bath area 52. The reinforcing protrusion 53 extends in the left and right direction and protrudes upward. The reinforcing protrusion 53 protrudes horizontally from the front sitz bath area 51 and the rear sitz bath area 52, thereby improving the structural strength at the connection between the front sitz bath area 51 and the rear sitz bath area 52.
