[0030] Please refer to Figures 1 to 4 , the seat cushion support structure and the vehicle provided by the present application will be described. The seat cushion support structure comprises a support frame, an elastic member 3 and a reinforcing frame 2, the support frame comprises a plurality of support plates 1 distributed in the left-right direction; the elastic member 3 is connected to two adjacent support plates 1, and is used to provide support force to the seat cushion 4 in the up-down direction; the reinforcing frame 2 is connected to the support plate 1, and the reinforcing frame 2 has a reinforcing inclined surface adapted to the side wall of the seat cushion 4, and the reinforcing inclined surface is used to provide support force to the seat cushion 4 from the oblique upper side.

[0031] Compared with the prior art, the cushion support structure provided by the utility model forms a framework with the support frame and the elastic piece 3, the elastic piece 3 provides upward supporting force to the cushion 4, and the support frame limits the displacement and deformation of the cushion 4 in the left-right direction. When the cushion 4 is subjected to downward pressure, the cushion 4 is elastically deformed and downwardly displaced by a certain amount, and the reinforcing frame 2 and the elastic piece 3 are subjected to downward pressure. Since the reinforcing frame 2 is connected to the support plate 1 and located below the cushion 4, the reinforcing inclined surface provides upward supporting force to the side wall of the cushion 4 after being subjected to stress, reduces the displacement of the cushion 4 in the left-right direction and the up-down direction, mainly relies on the elastic deformation of itself to relieve the pressure, avoids the interference between the cushion 4 and the support plate 1 when the position of the cushion 4 is reset, and the jamming phenomenon, and the collapse of the cushion 4. In addition, the reinforcing frame 2 is not located directly below the cushion 4, so the deformation of the cushion 4 caused by the rigid supporting force is avoided, and the comfort of the user is improved. The utility model adopts the scheme that the reinforcing frame 2 and the elastic piece 3 jointly provide supporting force to the cushion 4, ensures the softness of the cushion 4, improves the supporting force of the cushion 4, reduces the displacement after being subjected to stress, and avoids the collapse of the cushion 4.

[0032] Optionally, the reinforcing frame 2 is provided with one or more reinforcing frames, when the reinforcing frame 2 is provided with one reinforcing frame, the reinforcing frame is connected to the leftmost or rightmost support plate 1; when the reinforcing frame 2 is provided with multiple reinforcing frames, the reinforcing frames are connected to the two outermost support plates 1 respectively.

[0033] Optionally, the elastic piece 3 is a spring or a suspension spring.

[0034] In some embodiments, referring to Figure 4 The reinforcing frame 2 comprises a fixed plate 201, a connecting plate 202 and a reinforcing plate 203 which are distributed in a "U" shape, the fixed plate 201 is connected to the support plate 1, the reinforcing plate 203 forms a reinforcing inclined surface on the side away from the fixed plate 201, and the connecting plate 202 is used for connecting the fixed plate 201 and the reinforcing plate 203 and providing upward supporting force to the cushion 4.

[0035] The distribution mode of the "U" shaped structure improves the strength and rigidity of the reinforcing frame 2, the fixed plate 201 is attached to the support plate 1, the contact area with the support plate 1 is increased, and the firmness and reliability of the connection are improved. In the embodiment, the connecting plate 202 and the reinforcing plate 203 jointly provide supporting force to the cushion 4, and further reduce the displacement of the cushion 4.

[0036] Optionally, when the cushion 4 is not subjected to stress, there is a gap between the connecting plate 202 and the cushion 4, and the reinforcing inclined surface is attached to the cushion 4. When the cushion 4 is subjected to stress and moves downwardly, the connecting plate 202 provides upward supporting force to the cushion 4.

[0037] Optionally, the connecting plate 202 is parallel to the horizontal plane.

[0038] Optionally, the reinforcing slope is at an angle of 20° to the up-down direction. When the angle is too large, the cushion 4 is prone to be too thin, affecting the ride comfort, and when the angle of the reinforcing slope is too small, the support force provided is insufficient.

[0039] Optionally, the fixing plate 201 is welded to the support plate 1.

[0040] In some embodiments, referring to Figure 4 The reinforcing plate 203 comprises a reinforcing body connected to the connecting plate 202 and a reinforcing flange 2033 arranged at the outer edge of the reinforcing body, and the reinforcing flange 2033 is bent towards the side close to the fixing plate 201.

[0041] The arrangement of the reinforcing flange 2033 improves the strength and deformation resistance of the reinforcing plate 203, and can provide reliable support force to the cushion 4. The reinforcing flange 2033 is bent towards the side close to the fixing plate 201, avoiding interference with the cushion 4 after the cushion 4 is displaced under force, thereby affecting the resetting of the cushion 4 and causing the cushion 4 to collapse.

[0043] When the cushion 4 is displaced downward under force, the extension portions 2032 provide limiting and guiding effects to the displacement path of the cushion 4, avoiding displacement or deformation of the cushion 4 in the left-right direction, thereby avoiding the phenomenon of jamming when the cushion 4 is reset.

[0044] In some embodiments, referring to Figure 3 The support plate 1 is provided with a plurality of reinforcing ribs 103, the reinforcing frame 2 has reinforcing grooves 2011 adapted to the reinforcing ribs 103, and the reinforcing ribs 103 are inserted into the reinforcing grooves 2011.

[0045] The reinforcing ribs 103 can increase the strength and deformation resistance of the support plate 1, without relying on increasing the thickness of the support plate 1 to improve the strength, which is conducive to the lightweight of the whole vehicle. In addition, the reinforcing grooves 2011 are arranged on the reinforcing frame 2, the reinforcing ribs 103 are inserted into the reinforcing grooves 2011, the contact area between the reinforcing frame 2 and the support plate 1 is increased, the connection is improved, and the reinforcing ribs 103 and the reinforcing grooves 2011 are inserted and matched, which can also play a positioning and limiting role, and the installation efficiency is improved.

[0046] In some embodiments, referring to Figures 3 to 4The top surface of the reinforcing frame 2 is provided with a reinforcing groove 2022 which is concave downward, and the reinforcing frame 2 is provided with a lightening hole 2021 which is located in the reinforcing groove 2022.

[0047] The lightening hole 2021 is arranged on the reinforcing frame 2, which can reduce the weight of the reinforcing frame 2. However, the arrangement of the lightening hole 2021 can reduce the strength of the reinforcing frame 2, especially the deformation of the area around the lightening hole 2021. Therefore, the reinforcing groove 2022 is arranged on the reinforcing frame 2 to increase the strength of the reinforcing frame 2, and the lightening hole 2021 is arranged in the reinforcing groove 2022, which can reduce the deformation of the area around the lightening hole 2021.

[0048] In some embodiments, referring to Figure 1 and Figure 3 , the support plate 1 is provided with a mounting area which is concave to the left side or the right side, and the reinforcing frame 2 is connected to the mounting area.

[0049] The mounting area is concave to the surface of the support plate 1, thereby forming a staggered structure to improve the strength of the support plate 1. The reinforcing frame 2 is welded to the mounting area, which can reduce the deformation of the mounting area.

[0050] In some embodiments, referring to Figure 3 , the support plate 1 comprises a support body 101 and a support flange 102 which is arranged around the outer edge of the support body 101, the support flange 102 is bent towards the side close to the reinforcing frame 2, and the reinforcing frame 2 is connected to the support body 101.

[0051] The arrangement of the support flange 102 can avoid the direct exposure of the outer edge of the support body 101, which can prevent the sharp edge from scratching the operator. In addition, the support flange 102 can improve the strength and rigidity of the support plate 1. The support flange 102 is bent towards the side close to the reinforcing frame 2, which can avoid interference with other components in the vehicle.

[0052] Optionally, the support flange 102 can be processed by stamping forming process.

[0053] In some embodiments, referring to Figure 4 , the middle part of the fixing plate 201 is provided with a buffer groove 2012 which is concave to the side away from the support plate 1, and the buffer groove 2012 and the support plate 1 form a buffer space in the left-right direction.

[0054] The areas of the fixing plate 201 on both sides of the buffer groove 2012 are in contact with the support plate 1 to achieve the lamination connection. The buffer groove 2012 and the support plate 1 are spaced apart to form a buffer space, which can reduce the influence on the support plate 1 after the reinforcing frame 2 is stressed. In addition, compared with the bending and lamination of the fixing plate 201 and the support plate 1, the arrangement of the buffer groove 2012 can reduce the processing precision of the surface of the fixing plate 201 and reduce the production cost.

[0055] Based on the same inventive concept, the utility model still provides a kind of vehicle.The vehicle includes the seat cushion support structure described above.

[0056] The vehicle provided by the utility model adopts the seat cushion support structure described above, and the support frame and the elastic member 3 jointly form a framework, the elastic member 3 provides upward supporting force to the seat cushion 4, and the support frame limits the displacement amount and deformation amount of the seat cushion 4 in the left-right direction.When the seat cushion 4 is subjected to downward pressure, the seat cushion 4 elastically deforms and produces a certain displacement amount downward, and exerts downward pressure on the reinforcing frame 2 and the elastic member 3.Because the reinforcing frame 2 is connected to the support plate 1 and located below the seat cushion 4, the reinforcing inclined surface provides upward and oblique supporting force to the side wall of the seat cushion 4 after being stressed, reduces the displacement amount of the seat cushion 4 in the left-right direction and the up-down direction, mainly relies on the elastic deformation of itself to relieve pressure, avoids the interference between the seat cushion 4 and the support plate 1 when the position of the seat cushion 4 is reset, and the jamming phenomenon occurs, which leads to the problem of collapse of the seat cushion 4.In addition, the reinforcing frame 2 is not located directly below the seat cushion 4, and the situation that the deformation amount of the seat cushion 4 is affected by the rigid supporting force due to the large area of the seat cushion 4, which reduces the user's sense of comfort, does not occur.The utility model adopts the scheme that the reinforcing frame 2 and the elastic member 3 jointly provide supporting force to the seat cushion 4, ensures the softness of the seat cushion 4, improves the supporting force to the seat cushion 4, reduces the displacement amount after being stressed, and avoids the problem of collapse of the seat cushion 4.

[0057] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
