[0024] The following is for reference. Figures 1-3 The lower connecting plate 100 of the angle adjuster according to the embodiment of the present utility model can realize the angle adjustment function of the backrest frame 201, and can absorb part of the collision force when the vehicle is in collision, reduce the injury of the collision force to the occupants, improve the collision performance and safety of the vehicle, and the overall structure is relatively simple, which can reduce the manufacturing difficulty and setting cost.

[0025] like Figures 1-3As shown, according to an embodiment of the present invention, the lower connecting plate 100 of the adjuster is adapted to be connected between the backrest frame 201 and the seat cushion frame 202 of the seat 200; wherein, the lower connecting plate 100 of the adjuster includes a first connecting area 1, a middle collapsible area 2 and a second connecting area 3, the first connecting area 1 and the second connecting area 3 are respectively bent and connected to the two sides of the middle collapsible area 2, and the middle collapsible area 2 forms a middle collapsible groove 21. The first connecting area 1 forms a mounting clearance hole 11 for mounting the adjuster 203. The second connecting area 3 and / or the middle collapsible area 2 are provided with a connecting mounting part 31, which is used to connect with the seat cushion frame 202.

[0026] Specifically, the lower connecting plate 100 of the adjuster is a key load-bearing and connecting component of the car seat 200. Its core function is to strengthen the frame structure of the seat 200, transmit collision impact force, realize the backrest angle adjustment function, and improve the safety and riding comfort of the seat 200. By connecting the lower connecting plate 100 of the adjuster between the backrest frame 201 and the seat cushion frame 202 of the seat 200, the lower connecting plate 100 of the adjuster can be connected to the backrest frame 201 and the seat cushion frame 202 respectively. Figure 3 As shown, the lower connecting plate 100 of the angle adjuster is connected to the side plate of the seat cushion frame 202, which can realize the installation and fixation of the lower connecting plate 100 of the angle adjuster. The lower connecting plate 100 of the angle adjuster is also connected to the side plate of the backrest frame 201, which together with the side plate of the backrest frame 201 can form the mounting base of the angle adjuster 203, so as to realize the installation of the angle adjuster 203, and then the angle adjustment function of the backrest frame 201 can be realized through the angle adjuster 203.

[0027] Furthermore, the lower connecting plate 100 of the angle adjuster includes a first connecting area 1, an intermediate collapsible area 2, and a second connecting area 3. The first connecting area 1 has a mounting clearance hole 11 for installing the angle adjuster 203. The mounting clearance hole 11 is used to avoid the installation space of the angle adjuster 203 to ensure the reliable installation and operation of the angle adjuster 203. The connecting mounting part 31 is used to connect the seat frame 202. The connecting mounting part 31 can be provided only in the second connecting area 3 or the intermediate collapsible area 2, or it can be provided in both the second connecting area 3 and the intermediate collapsible area 2 at the same time, so as to achieve reliable installation and fixation of the lower connecting plate 100 of the angle adjuster and ensure the reliable operation of the lower connecting plate 100 of the angle adjuster. The connecting mounting part 31 and the seat frame 202 can be connected by welding or connectors to improve the connection strength between the two.

[0028] In such Figures 1-2In the embodiment shown, a connecting mounting part 31 is provided in both the second connecting area 3 and the intermediate collapsing area 2. This increases the number of connecting mounting parts 31, improves the connection reliability between the lower connecting plate 100 of the adjuster and the seat frame 202, and thus ensures the reliable operation of the lower connecting plate 100 of the adjuster.

[0029] Furthermore, by bending and connecting the first connecting area 1 and the second connecting area 3 to the two sides of the middle collapsing area 2, the first connecting area 1 and the second connecting area 3 can be connected to the middle collapsing area 2 respectively, making the lower connecting plate 100 of the adjuster a whole structure. This can improve the structural strength and operational reliability of the lower connecting plate 100 of the adjuster. Moreover, by setting the first connecting area 1 and the second connecting area 3 to the two sides of the middle collapsing area 2 respectively, the first connecting area 1 and the second connecting area 3 can be set opposite to each other, so that the first connecting area 1 and the second connecting area 3 can be connected to the backrest frame 201 and the seat cushion frame 202 respectively, which can avoid interference and improve the connection reliability between the lower connecting plate 100 of the adjuster and the backrest frame 201 and the seat cushion frame 202.

[0030] Furthermore, the bending connection method can change the cross-sectional shape and stress distribution of the lower connecting plate 100 of the angle adjuster at the connection between the first connecting area 1 and the intermediate collapsing area 2, which can effectively disperse stress and improve the structural strength of the lower connecting plate 100 of the angle adjuster at the connection between the first connecting area 1 and the intermediate collapsing area 2. At the same time, it can change the cross-sectional shape and stress distribution of the lower connecting plate 100 of the angle adjuster at the connection between the second connecting area 3 and the intermediate collapsing area 2, which can effectively disperse stress and improve the structural strength of the lower connecting plate 100 of the angle adjuster at the connection between the second connecting area 3 and the intermediate collapsing area 2, thus effectively improving the reliability of the lower connecting plate 100 of the angle adjuster.

[0031] Furthermore, the first connecting region 1 and the second connecting region 3 are respectively bent and connected to the intermediate crumple region 2 to form an intermediate crumple groove 21 in the intermediate crumple region 2. That is, the intermediate crumple region 2 can provide space for the intermediate crumple groove 21 to achieve a reliable arrangement of the intermediate crumple groove 21. When the collision force is transmitted to the seat 200 during a vehicle collision, the intermediate crumple groove 21 can deform and crumple to absorb part of the collision force, reduce the injury of the collision force to the occupant, improve the collision performance and safety of the vehicle. In addition, the intermediate crumple groove 21 is constructed to have a certain length, which can improve the reliability of the intermediate crumple groove 21 in absorbing the collision force.

[0032] According to the embodiment of the present utility model, the lower connecting plate 100 of the angle adjuster can be installed and fixed by connecting the lower connecting plate 100 of the angle adjuster between the backrest frame 201 and the seat cushion frame 202, and providing a connecting mounting part 31 in the second connecting area 3 and / or the intermediate crumple area 2. The installation avoidance hole 11 formed in the first connecting area 1 can reliably install the angle adjuster 203, thereby realizing the angle adjustment function of the backrest frame 201. In addition, the intermediate crumple groove 21 formed in the intermediate crumple area 2 can absorb part of the collision force when the vehicle collides, reduce the injury of the collision force to the occupants, improve the collision performance and safety of the vehicle, and the overall structure is relatively simple, which can reduce the manufacturing difficulty and setting cost.

[0033] In some embodiments, a first bending flange 22 is formed at the connection between the first connecting region 1 and the intermediate collapsing region 2, and a second bending flange 23 is formed at the connection between the second connecting region 3 and the intermediate collapsing region 2; wherein, a collapse hole 24 is formed at the first bending flange 22 and / or the second bending flange 23.

[0034] Specifically, the first connecting region 1 is connected to the intermediate collapsing region 2, and a first bent flange 22 is formed at the connection. The first bent flange 22 can be used to change the cross-sectional shape and stress distribution at the connection between the first connecting region 1 and the intermediate collapsing region 2, thereby reducing stress concentration, improving the structural strength of the connection between the first connecting region 1 and the intermediate collapsing region 2, and forming a smooth transition at the connection to avoid scratching the user. At the same time, the second connecting region 3 is connected to the intermediate collapsing region 2, and a second bent flange 23 is formed at the connection. The second bent flange 23 can be used to change the cross-sectional shape and stress distribution at the connection between the second connecting region 3 and the intermediate collapsing region 2, thereby reducing stress concentration, improving the structural strength of the connection between the second connecting region 3 and the intermediate collapsing region 2, and forming a smooth transition at the connection to avoid scratching the user.

[0035] Furthermore, the core function of the crumple zone 24 is to absorb and disperse collision energy through controllable deformation, thereby reducing the impact on the occupants and minimizing the injury caused by the collision force. The crumple zone 24 can be formed at the first bend flange 22 or the second bend flange 23, or both the first bend flange 22 and the second bend flange 23 can be formed. That is, the first bend flange 22 and / or the second bend flange 23 can provide space for the crumple zone 24. In this way, the crumple zone 24 can be formed on the lower connecting plate 100 of the adjuster, so that when the collision force is transmitted to the seat 200 during a vehicle collision, the lower connecting plate 100 of the adjuster can deform along the preset path of the crumple zone 24 to consume a large amount of collision energy.

[0036] In some embodiments, the length of the first bending flange 22 is greater than the length of the second bending flange 23, and the collapse hole 24 is formed at the first bending flange 22 and extends toward the first connecting region 1 and the intermediate collapse region 2.

[0037] Specifically, the length of the first bend flange 22 is greater than the length of the second bend flange 23, that is, the connection length between the first connecting area 1 and the intermediate collapsible area 2 is greater than the connection length between the second connecting area 3 and the intermediate collapsible area 2. The collapsible hole 24 is formed at the first bend flange 22 and extends toward the first connecting area 1 and the intermediate collapsible area 2. The collapsible hole 24 can be formed at the connection between the first connecting area 1 and the intermediate collapsible area 2, so that the collapsible hole 24 can extend toward the first connecting area 1 and the intermediate collapsible area 2 at the same time. That is, a part of the collapsible hole 24 is located in the first connecting area 1 and another part is located in the intermediate collapsible area 2. This can increase the setting area of ​​the collapsible hole 24 and improve the reliability of the lower connecting plate 100 of the angle adjuster deforming at the collapsible hole 24 to absorb the impact force.

[0038] In other words, when the collision force of the vehicle is transmitted to the seat 200, the first connecting area 1 and the middle crumple area 2 on the lower connecting plate 100 of the adjuster can deform at the crumple hole 24 at the same time, which can improve the reliability of the lower connecting plate 100 of the adjuster deforming at the crumple hole 24 and improve its reliability in absorbing the collision force.

[0039] In some embodiments, the first bending flange 22 includes a first extension 221 and a second extension 222, the first extension 221 and the second extension 222 are bent and connected, the first extension 221 and the second connection area 3 are distributed in a direction away from the mounting clearance hole 11, and the collapse hole 24 is formed at the second extension 222.

[0040] Specifically, the first bending flange 22 is formed at the connection between the first connecting region 1 and the intermediate collapsing region 2. The first bending flange 22 includes a first extension segment 221 and a second extension segment 222, that is, the first extension segment 221 and the second extension segment 222 are both located between the first connecting region 1 and the intermediate collapsing region 2, so as to jointly separate the first connecting region 1 and the intermediate collapsing region 2, and bend the first extension segment 221 and the second extension segment 222 together. That is, the extension directions of the first extension segment 221 and the second extension segment 222 are different, which can make the first bending flange 22 a whole, thereby improving the structural strength of the lower connecting plate 100 of the angle adjuster at the first bending flange 22.

[0041] Furthermore, by distributing the first extension segment 221 and the second connecting area 3 along a direction away from the mounting clearance hole 11, the second connecting area 3 can be positioned on the side of the first extension segment 221 away from the mounting clearance hole 11. This allows the mounting clearance hole 11, the first extension segment 221, and the second connecting area 3 to be arranged sequentially. The first extension segment 221 can be positioned between the mounting clearance hole 11 and the second connecting area 3, thus separating the connecting mounting portions 31 on the mounting clearance hole 11 and the second connecting area 3. This facilitates the installation of the angle adjuster 203 or the fixing of the lower connecting plate 100 of the angle adjuster. Simultaneously, the collapse hole 24 is formed at the second extension segment 222, allowing the collapse hole 24 to be positioned between the first connecting area 1 and the intermediate collapse area 2. This enables the collapse hole 24 to extend towards the first connecting area 1 and the intermediate collapse area 2, thereby increasing the installation area of ​​the collapse hole 24 and improving the reliability of the lower connecting plate 100 of the angle adjuster in deforming at the collapse hole 24 to absorb the impact force.

[0042] In some embodiments, there are two connecting mounting portions 31, one connecting mounting portion 31 is located in the second connecting region 3, and the other connecting mounting portion 31 is located in the intermediate collapsing region 2, and the other connecting mounting portion 31 is distributed in the intermediate collapsing region 2 along the direction away from the mounting clearance hole 11 with the second extension 222.

[0043] Specifically, the connecting mounting part 31 is used to connect the lower connecting plate 100 of the adjuster to the seat frame 202. By setting two connecting mounting parts 31, the lower connecting plate 100 of the adjuster and the seat frame 202 can be connected simultaneously through the two connecting mounting parts 31, which can improve the connection reliability between the two. Furthermore, by setting one of the two connecting mounting parts 31 in the second connection area 3 and the other in the middle collapsible area 2, the two connecting mounting parts 31 can be spaced apart, so that there can be a certain distance between the two connecting mounting parts 31. Thus, the lower connecting plate 100 of the adjuster and the seat frame 202 can be connected simultaneously at two positions through the two connecting mounting parts 31, which can avoid stress concentration and improve the connection stability between the two.

[0044] Furthermore, the connecting mounting portion 31 and the second extension 222 located in the intermediate crumple zone 2 are distributed in a direction away from the mounting clearance hole 11. This allows the connecting mounting portion 31 located in the intermediate crumple zone 2 to be positioned on the side of the second extension 222 away from the mounting clearance hole 11. In other words, the mounting clearance hole 11, the second extension 222, and the connecting mounting portion 31 can be arranged sequentially. The second extension 222 can be positioned between the mounting clearance hole 11 and the connecting mounting portion 31, thus separating the connecting mounting portion 31 from the mounting clearance hole 11 to avoid interference and improve the reliability of installing and fixing the angle adjuster 203 and the lower connecting plate 100 of the angle adjuster.

[0045] The connecting mounting part 31 can be configured as a connecting mounting hole, through which the connector can be simultaneously inserted into the connecting mounting hole and the seat frame 202, so as to achieve a reliable connection between the lower connecting plate 100 of the adjuster and the seat frame 202, thereby achieving reliable installation and fixation of the lower connecting plate 100 of the adjuster.

[0046] In some embodiments, the first extension 221 and the second extension 222 are connected by an arc-shaped transition section 223, and a crumple reinforcement section 25 is formed on the side edge away from the first connection area 1 in the intermediate crumple region 2. The crumple reinforcement section 25 and the arc-shaped transition section 223 are distributed in a direction away from the mounting clearance hole 11.

[0047] Specifically, by connecting the first extension segment 221 and the second extension segment 222 with an arc-shaped transition segment 223, the arc-shaped transition segment 223 can be connected between the first extension segment 221 and the second extension segment 222, thus achieving the connection between the first extension segment 221 and the second extension segment 222. This makes the first bending flange 22 a whole, which can improve the structural strength of the lower connecting plate 100 of the angle adjuster at the first bending flange 22. Furthermore, the arc-shaped transition segment 223 can form a smooth transition between the first extension segment 221 and the second extension segment 222, avoiding local stress concentration and preventing scratches to the user. At the same time, the intermediate collapse area 2 is far away from the first connecting area 1. A crumple-reinforced section 25 is formed at one edge of the angle adjuster. The crumple-reinforced section 25 is used to enhance the structural strength of the lower connecting plate 100 of the angle adjuster at this point. The crumple-reinforced section 25 and the arc-shaped transition section 223 are distributed in a direction away from the mounting clearance hole 11. The crumple-reinforced section 25 can be set on the side of the arc-shaped transition section 223 away from the mounting clearance hole 11. In other words, the arc-shaped transition section 223 can be set between the mounting clearance hole 11 and the crumple-reinforced section 25. This allows the arc-shaped transition section 223 to separate the mounting clearance hole 11 and the crumple-reinforced section 25 to avoid interference and improve the reliability of the angle adjuster 203 and the reliability of the operation of the crumple-reinforced section 25.

[0048] The crumple reinforcement section 25 can be extended along the edge of the middle crumple region 2 to increase the length of the crumple reinforcement section 25 and further improve its reliability in enhancing the local strength of the lower connecting plate 100 of the angle adjuster.

[0049] In some embodiments, the first connecting region 1 is formed with a first connecting plane 12, and a mounting clearance hole 11 is formed on the first connecting plane 12; and / or, the intermediate collapsible region 2 is formed with an intermediate collapsible plane 26, the second connecting region 3 is formed with a second connecting plane 32, and there are two connecting mounting portions 31, one connecting mounting portion 31 is formed on the intermediate collapsible plane 26, and the other connecting mounting portion 31 is formed on the second connecting plane 32.

[0050] Specifically, the first connecting region 1 has a first connecting plane 12 with a large area. The mounting clearance hole 11 is formed on the first connecting plane 12, which provides space for the mounting clearance hole 11 and allows the mounting clearance hole 11 to be large enough to improve the reliability of clearance for the adjuster 203. Meanwhile, the intermediate collapsible region 2 has an intermediate collapsible plane 26, and the second connecting region 3 has a second connecting plane 32. One of the two connecting mounting parts 31 is formed on the intermediate collapsible plane 26, and the other is formed on the second connecting plane 32. The intermediate collapsible plane 26 and the second connecting plane 32 can each provide space for a connecting mounting part 31. Thus, the two connecting mounting parts 31 can be formed in the intermediate collapsible region 2 and the second connecting region 3, and the two connecting mounting parts 31 can be spaced apart, which can improve the reliability and stability of the connection between the lower connecting plate 100 of the adjuster and the seat frame 202.

[0051] In some embodiments, the first connecting plane 12 and the second connecting plane 32 are located in the same plane, and the intermediate collapsing plane 26 is distributed parallel to and spaced apart from the first connecting plane 12.

[0052] Specifically, the first connecting plane 12 and the second connecting plane 32 are set in the same plane, and the intermediate crumple plane 26 is distributed parallel to and spaced apart from the first connecting plane 12. This allows the intermediate crumple plane 26 to be spaced apart from both the first connecting plane 12 and the second connecting plane 32, so that the first connecting area 1 and the second connecting area 3 can be bent and connected to both sides of the intermediate crumple area 2, so that the intermediate crumple area 2 can form an intermediate crumple groove 21. When the collision force is transmitted to the seat 200 during a vehicle collision, the intermediate crumple groove 21 can deform and crumple to absorb part of the collision force, reduce the injury of the collision force to the occupant, and improve the collision performance and safety of the vehicle.

[0053] Among them, such as Figures 1-2 As shown, the intermediate crumple plane 26 is disposed on the inner side of the first connecting plane 12 and the second connecting plane 32, so that the intermediate crumple groove 21 is constructed to be recessed towards the inside of the vehicle, with the inside being the side facing the center line of the vehicle, in order to avoid interference between the intermediate crumple groove 21 and the seat frame 202, thereby improving the reliability of installing the lower connecting plate 100 of the adjuster, and thus improving the reliability of the operation of the lower connecting plate 100 of the adjuster.

[0054] In some embodiments, the lower connecting plate 100 of the angle adjuster further includes a reinforcing flange 4, which is bent and connected to the outer edge of the first connecting area 1 and the intermediate collapsing area 2.

[0055] Specifically, the reinforcing flange 4 is used to enhance the structural strength of the lower connecting plate 100 of the turntable. The reinforcing flange 4 is bent and connected to the outer edge of the first connecting area 1 and the intermediate collapsing area 2, so that the reinforcing flange 4 can simultaneously enhance the structural strength of the lower connecting plate 100 of the turntable from the edges of the first connecting area 1 and the intermediate collapsing area 2. The reinforcing flange 4 can be extended from the first connecting area 1 to the intermediate collapsing area 2, which can increase the setting length of the reinforcing flange 4, thereby increasing the reliability of enhancing the structural strength of the lower connecting plate 100 of the turntable. At the same time, the reinforcing flange 4 can also be extended outward from the lower connecting plate 100 of the turntable by a certain length, which can increase the setting area of ​​the reinforcing flange 4, further increasing the reliability of enhancing the structural strength of the lower connecting plate 100 of the turntable.

[0056] This utility model also proposes a vehicle.

[0057] The vehicle according to the present utility model includes a seat cushion frame 202, a backrest frame 201 and an adjuster lower connecting plate 100 of any of the above embodiments. The connecting mounting part 31 is detachably connected to the seat cushion frame 202. The backrest frame 201 is rotatably connected to the first connecting area 1 through the adjuster 203, and the mounting clearance hole 11 is used to install the clearance adjuster 203.

[0058] Specifically, the seat cushion frame 202 and backrest frame 201, as the core support structures of the seat 200, respectively provide support and protection for the upper and lower body of the human body. They work together to ensure driving safety, comfort, and stability. The lower connecting plate 100 of the adjuster connects between the seat cushion frame 202 and the backrest frame 201, and includes a first connecting area 1, a middle collapsible area 2, and a second connecting area 3. The first connecting area 1 has a mounting clearance hole 11, which is used to avoid the installation of the adjuster 203, ensuring proper positioning of the adjuster 203. Reliable installation allows the backrest frame 201 to be rotatably connected to the first connection area 1 via the angle adjuster 203, enabling the backrest frame 201 to rotate relative to the first connection area 1 and realize the angle adjustment function of the backrest frame 201. Furthermore, connection mounting parts 31 are formed in the middle collapsible area 2 and the second connection area 3, respectively. The connection mounting parts 31 are used to connect the seat cushion frame 202, thereby allowing the lower connecting plate 100 of the angle adjuster to be connected to the seat cushion frame 202 at two positions simultaneously, which can improve the reliability and stability of the connection between the two, and thus improve the reliability of the operation of the lower connecting plate 100 of the angle adjuster.

[0059] Furthermore, the connecting mounting part 31 is detachably connected to the seat cushion frame 202. The connecting mounting part 31 can be configured as a connecting mounting hole, and bolts and other connecting parts can be passed through both the connecting mounting hole and the seat cushion frame 202. This allows for reliable installation and fixation of the lower connecting plate 100 of the adjuster, and facilitates the connection or separation of the lower connecting plate 100 of the adjuster from the seat cushion frame 202. This makes it easy to install or remove the lower connecting plate 100 of the adjuster, so that it can be replaced when it is damaged or fails, thereby reducing the installation cost.
