Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a base support component and a shock-absorbing seat using the same. Background Art

[0002] During the use of the car seat, the base is used to support the seat. On the one hand, the strength of the base will directly affect the overall service life of the car seat. During the driving process, the car will inevitably be bumpy. In the bumpy state, although the shock-absorbing mechanism between the base and the seat can play a role in alleviating the bumps, it still cannot completely avoid the fatigue of the base under long-term bumpy conditions. On the other hand, the strength of the base will also affect the comfort of the seat during use. Specifically, due to the shock-absorbing mechanism between the seat and the base, when braking or other situations may cause the human body to lean forward in the direction of the car's travel due to inertia, the instantaneous pulling force on the car base will also increase synchronously. At this time, if the base is not strong enough, it will not only cause the human body to lean forward too much due to inertia, resulting in a loss of comfort strength, but also may aggravate the damage to the base due to the accumulation effect of the human body's inertia during long-term use, thereby shortening its service life.

[0003] In this regard, for example, the shock-absorbing seat with announcement number CN217598398U and the car seat using the same are provided with a pair of deformable brackets between the seat support frame and the bottom plate, each deformable bracket includes two connecting rods arranged in a scissor-like manner, and the ends of the two connecting rods close to the elastic component have a fixed hinge point with the bottom plate, and the ends of the two connecting rods away from the elastic component form a sliding fit structure with the bottom plate. With the realization of the shock-absorbing process of the car seat, there is no fixed fit point between the sliding fit parts. For this car seat, when braking or other situations may cause the human body to have a tendency to lean forward in the direction of the car's travel due to inertia, since the end of the connecting rod away from the elastic component, that is, corresponding to the back of the human body, is in a sliding fit with the bottom plate, the pair of deformable brackets will further assist the human body to lean forward in the direction of the car's travel due to inertia, thereby exacerbating the discomfort caused by inertia.

[0004] Furthermore, the ends of the two connecting rods and the base plate with fixed hinge points are only connected to the base plate by hinge shafts. The base plate itself does not support this end of the connecting rod, which directly affects the use strength of the end of the connecting rod and the base plate forming a fixed hinge point.

[0005] Therefore, with regard to the shock absorption of automobile seats in the prior art, for the deformable bracket structure designed between the base plate and the seat, while cooperating with the realization of its shock absorption function, it is also necessary to take into account its overall strength of use, so as to improve the comfort of human use and extend the service life.

DETAILED DESCRIPTION

[0036] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0037] Embodiment 1:

[0038] See also Figures 1 to 4 As shown, this embodiment provides a base support assembly, including: a base plate 1, a seat support frame 2 arranged above the base plate 1, and a pair of scissor-type support frames and an elastic connection assembly arranged between the base plate 1 and the seat support frame 2; wherein each scissor-type support frame includes two cross-matched support cantilevers 3, and the two support cantilevers 3 are hingedly connected at approximately the middle position.

[0039] It should be noted that when the base support assembly is used in a specific car seat, in combination with the position of the user, the elastic connection assembly is located on the side of the car seat close to the user's legs so that the user can adjust the elastic connection assembly.

[0040] On the basis of the above structure, further speaking, the end of one of the two support cantilevers 3 adjacent to the elastic connection component is slidably matched with the seat support frame 2, and the end of the support cantilever 3 away from the elastic connection component is hingedly matched with the base plate 1; and the end of the other support cantilever 3 adjacent to the elastic connection component is slidably matched with the base plate 1, and the end of the support cantilever 3 away from the elastic connection component is hingedly matched with the seat support frame 2. That is to say, for a pair of scissor-type support frames, the end adjacent to the elastic connection component is a slidable end, and the end away from the elastic connection component is a relatively fixed end. The fixed end here refers to an unchanged position relative to the base plate 1, and does not refer to a fixed and immovable connection structure. It should be explained here that a linkage rod is also provided between the ends of the support cantilevers 3 in a pair of scissor-type support frames that are respectively slidably matched with the base plate 1.

[0041] Under this structure, for the shock-absorbing seat using the base support assembly, when the user's body leans forward due to inertia due to braking or other situations, the end of the supporting cantilever 3 that forms a fixed hinge point with the base plate 1 and the seat support frame 2 is located in the opposite direction of the user's body leaning forward, so it can play an opposite inhibitory role in the tendency of the user's body to lean forward, thereby reducing the discomfort caused by inertia to the human body.

[0042] Based on the above situation, further considering further improving the use strength of a pair of scissor-type support frames, this embodiment also makes the following design:

[0043] First, roughly, the end of the support cantilever 3 of the two support cantilevers 3 that is hingedly matched with the bottom plate 1 is provided with a connector; the support cantilever 3 is hingedly connected to the connector, and the connector is fixed on the bottom plate 1. In combination with the accompanying drawings, an optional implementation is given as an example, the connector is an L-shaped structure; the connector includes a transverse support plate 41 for fixing on the bottom plate 1 and a longitudinal support plate 42 vertically connected to the transverse support plate 41; the longitudinal support plate 42 is connected to the support cantilever 3 by bolts 5.

[0044] Furthermore, a strip-shaped clearance groove 43 is provided on the transverse support plate 41 for the end of the support cantilever 3 to pass through. The end of the support cantilever 3 passing through the clearance groove 43 is formed with a semicircular connector suitable for sliding friction with the bottom plate 1.

[0045] In addition, it should be noted that a transition reinforcement member 9 is provided between the bottom plate 1 and the longitudinal support plate 42 ; the transition reinforcement member 9 is fastened to the bottom plate 1 by bolts 5 .

[0046] The support cantilever 3 is hingedly connected to the connecting piece, and the connecting piece is fixed on the bottom plate 1. Under this structure, on the one hand, the bottom plate 1 can form a supporting function for the end of the support cantilever 3 that is fixedly hinged and matched with the bottom, thereby enhancing the use strength of the support cantilever 3. In addition, by providing a strip-shaped clearance groove 43 suitable for the end of the support cantilever 3 to pass through on the transverse support plate 41 of the connecting piece, the design height of the overall support cantilever 3 relative to the bottom plate 1 can be reduced, and the higher the design height of the support cantilever 3 relative to the bottom plate 1, the lower the strength of the corresponding support cantilever 3. Therefore, this embodiment, on the basis of taking into account the supporting function of the bottom plate 1 for the support cantilever 3, can also reduce the support height of the support cantilever 3 relative to the bottom plate 1, thereby further strengthening the use strength of the overall base support assembly, so that it can also strengthen the use strength of the seat base on the basis of taking into account the seat shock absorption function.

[0047] In addition, it should be noted that a first track 61 for slidingly cooperating with the support cantilever 3 is provided at a portion of the bottom plate 1 adjacent to the elastic connection component; and the support cantilever 3 slidingly cooperating with the bottom plate 1 is connected to the first track 61 via a first roller 62. A second track 71 for slidingly cooperating with the support cantilever 3 is provided at a portion of the seat support frame 2 adjacent to the elastic connection component; and the support cantilever 3 slidingly cooperating with the seat support frame 2 is connected to the second track 71 via a second roller 72. Here, the first track 61 and the second track 71 may optionally adopt tracks of the same structure, and the first roller 62 and the second roller 72 may also adopt rollers of the same structure.

[0048] Finally, it is necessary to explain that the elastic connection assembly includes two columnar compression springs 81 arranged side by side, a fixing frame arranged at the ends of the two columnar compression springs 81 facing the seat support frame 2, and an adjustment structure arranged on the seat support frame 2 suitable for abutting with the fixing frame through an inclined surface; the adjustment structure includes a pressure block abutting with the fixing frame, and a push rod connected to the pressure block suitable for driving the pressure block to move horizontally; when the pressure block moves horizontally, the fixing frame synchronously moves perpendicular to the movement direction of the pressure block to adjust the height of the two columnar compression springs 81. Regarding the elastic connection assembly here, any mature means in the prior art can be selected, such as the elastic connection assembly disclosed in the announcement number CN 217598398 U. This embodiment does not make an absolute limitation on its structure and use principle, and this embodiment will not be repeated.
