Description

Technical Field

[0001] This utility model relates to a vehicle seat component, and more particularly to a rotating shock-absorbing seat frame platform for automobiles. Background Technology

[0002] Car seats are an indispensable piece of equipment inside a vehicle. Their main functions are to support occupants, dampen shocks and vibrations transmitted during vehicle operation, and provide comfortable and safe seating conditions for drivers and passengers.

[0003] To ensure the performance of car seats, existing technologies generally use serpentine springs to achieve shock absorption in the seat frame. However, since the deformation of serpentine springs is limited, the improvement in seat comfort is limited. For vehicles with poor shock absorption or low requirements, seats with serpentine spring frames are also less comfortable.

[0004] Existing technologies also include seat shock absorber structures that employ X-shaped hinge components. These components achieve shock absorption through high-low deformation with elastic preload. To allow for vertical deformation, one end of the X-shaped hinge component is hinged and rotated, while the other end utilizes a sliding fit to achieve high-low deformation. This structure significantly improves seat comfort, but it requires high manufacturing and assembly precision. Excessive gaps can lead to rattling and looseness, while insufficient gaps can result in uneven sliding and jamming. Furthermore, over time, gaps and foreign objects can accumulate in the sliding joints, causing discomfort during use and affecting performance. Additionally, due to structural limitations, this shock absorber structure requires considerable space for installation. However, limited interior space and seat height constraints make installation difficult, and it also precludes the installation of ventilation and heating components, thus limiting its applicability.

[0005] Therefore, it is necessary to make structural improvements to the existing seat frame. The structure is simple, which can appropriately reduce the manufacturing precision requirements and avoid problems such as abnormal noise, looseness, uneven movement, and jamming. Installation and use do not require a large height space, which improves seat comfort. At the same time, there is enough space to arrange ventilation and heating components. Utility Model Content

One end of the connecting rod II and the other end are respectively hinged to the base and the upper support frame in the vertical direction via the transition connecting rod II.

[0010] The elastic preload is adjustable.

[0011] Furthermore, the connecting rod assembly I and connecting rod assembly II are two sets arranged side by side.

[0012] Furthermore, the elastic preload is applied at any hinge position of the linkage mechanism, and at that hinge position, an upward swinging tendency is formed.

[0014] Furthermore, the linkage mechanism also includes hollow shaft I and hollow shaft II. Link I or transition link I is hinged to the base or upper support frame via hollow shaft I, and link II or transition link II is hinged to the base or upper support frame via hollow shaft II. The elastic preload is applied by torsion spring I and torsion spring II. Torsion spring I passes through hollow shaft I, with one end abutting against a set position on hollow shaft I and the other end abutting against a corresponding fixed position. Torsion spring II passes through hollow shaft II, with one end abutting against a set position on hollow shaft II and the other end abutting against a corresponding fixed position.

[0015] The elastic force of torsion spring I and / or torsion spring II is adjustable, making the elastic preload adjustable.

[0016] Furthermore, both the base and the upper support frame are frame structures; the hollow shaft I is rotatably supported at the rear of the upper support frame, the upper end of the connecting rod I is fixed to the hollow shaft I, and the transition connecting rod I is hinged to the corresponding side of the base; the hollow shaft II is rotatably supported at the front of the upper support frame, the transition connecting rod II is fixed to the hollow shaft II, and the lower end of the connecting rod II is hinged to the corresponding side of the base; the damper is installed between the front of the base and the front of the upper support frame to form damping between the base and the upper support frame.

The torsion spring I passes through the hollow shaft I, with one bearing end abutting against a limiting groove opened on the wall of the hollow shaft I, and the other bearing end extending out of the hollow shaft I and abutting against the rear support lug.

[0018] The linkage mechanism also includes a spring force adjustment mechanism disposed on the upper support frame.

This can appropriately reduce the manufacturing precision requirements and avoid problems such as abnormal noise, looseness, uneven movement, and jamming. The rotating linkage mechanism does not require a large height space, thus having a large stroke, greatly improving seat comfort. At the same time, there is enough space to arrange ventilation and heating components. The entire structure of this utility model integrates shock absorption and frame into one unit, which is simple in structure, easy to install, and cost-effective. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Figure 1 This is an isometric view of the present invention;

[0023] Figure 2 This is an exploded view of the present invention. Detailed Implementation

[0024] like Figure 1-2As shown: The automotive rotary shock-absorbing seat frame platform of this embodiment includes a base 1, an upper support frame 2 and a linkage mechanism 3 formed by hinged connection. The linkage mechanism 3 is hinged between the base 1 and the upper support frame 2 and can be driven to deform in the vertical direction. The linkage mechanism is subjected to an elastic preload force that deforms upward.

[0025] A linkage mechanism refers to a component consisting of several links that are hinged together. Generally, it is an X-shaped hinge to achieve vertical deformation, which will not be elaborated here. Of course, other hinges can also be used between the links, such as direct inclined hinges. By applying a set elastic preload, a vertical deformation structure can also be formed, which will not be elaborated here. Since all mating pairs in this structure are hinged, the sliding pairs in the prior art are eliminated, thus solving the technical problems of sliding pairs.

[0026] In this embodiment, a damper 4 is also included. The damper 4 is disposed between the base 1 and the upper support frame 2 to form damping in the vertical direction. The damper 4 belongs to the mechanical structure that can form damping effect in the prior art, such as the piston damper, etc., which will not be described in detail here.

[0027] In this embodiment, the elastic preload is adjustable. The elastic preload generally refers to the force applied by an elastic element, which can realize reciprocating elastic compression and release, so that the linkage mechanism 3 can reciprocate up and down to complete the shock absorption, and has the general function of a shock absorber; it can be a spring, a spring sheet, etc., which will not be described in detail here.

[0028] In this embodiment, the linkage mechanism 3 includes linkage assembly I and linkage assembly II. Linkage assembly I includes linkage I 301 and a transition linkage I 3011 hinged to linkage I 301, which can swing vertically. Linkage assembly II includes linkage II 302 and a transition linkage II 3021 hinged to linkage II 302, which can swing vertically. Linkage I 301 and linkage II 302 are connected by an X-shaped cross hinge that can swing vertically. One end and the other end of linkage I 301 are respectively hinged to base 1 and upper support frame 2 via transition linkage I 3011, which can swing vertically. One end and the other end of linkage II 302 are respectively hinged to base 1 and upper support frame 2 via transition linkage II 3021, which can swing vertically. As shown in the figure, one end of linkage I 301... One end can be directly hinged to the base, and the other end can be hinged to the upper support frame 2 via transition link I 3011, and vice versa; of course, one end of link II 302 can be directly hinged to the base, and the other end can be hinged to the upper support frame 2 via transition link II 3021, and vice versa, which will not be elaborated here; in this structure, the transition link I 301 and the transition link II 3021 form a hinged connection between link I 301 and link II 302 and the base 1 and the upper support frame 2, so that the linkage mechanism 3 will not undergo lateral deformation when it undergoes deformation in the vertical direction, and the structure is relatively simple; X-shaped hinge refers to link I 301 and link II 302 crossing and hinged; the hinges mentioned in this utility model all refer to swinging in the vertical direction, of course, it is desirable to be a single degree of freedom swing, which will not be elaborated here.

[0029] In this embodiment, the connecting rod assembly I and connecting rod assembly II are two sets arranged side by side; as shown in the figure, in this structure, connecting rod I 301 and transition connecting rod I 3011, as well as connecting rod II 302 and transition connecting rod II 3021 are two in number and arranged side by side in the transverse direction, which has relatively stable deformation and support, and will not be described in detail here.

[0030] In this embodiment, the elastic preload is applied to any hinge position of the linkage mechanism 3, and an upward swinging tendency is formed at that hinge position; the hinge position refers to the position where the linkage mechanism 3 is connected to the base 1 and the upper support frame 2 and all the hinge connections in the linkage mechanism 3; the elastic preload can be applied to any or several hinge positions and in order to make the linkage mechanism swing upward, the purpose of the utility model can be achieved.

[0031] In this embodiment, the upper end of the connecting rod I 301 is hinged to the upper support frame 2. The upper support frame 2 needs to be provided with a corresponding hinge position, which is a typical mechanical adaptation structure and will not be described in detail here. The lower end of the connecting rod I 301 is hinged to the base 1 through the transition connecting rod I 3011. Similarly, the base 1 needs to be provided with a corresponding hinge position, which is a typical mechanical adaptation structure and will not be described in detail here. Furthermore, the transition connecting rod I 3011 forms an upward angle with the connecting rod I 301. In this structure, it can ensure that there is sufficient swing space between the transition connecting rod I 3011 and the connecting rod I 301, and it does not occupy space. The upper space can be used to arrange other functional components; similarly, the upper end of the connecting rod II 302 is hinged to the upper support frame 2 through the transition connecting rod II 3021. The upper support frame 2 needs to be provided with a corresponding hinge position, which is a common mechanical adaptation structure and will not be described in detail here; the lower end of the connecting rod II 302 is hinged to the base 1. Similarly, the base 1 needs to be provided with a corresponding hinge position, which is a common mechanical adaptation structure and will not be described in detail here; and the transition connecting rod II 3021 forms an upward angle with the connecting rod II 302. Of course, it has the same effect as the connecting rod I 301 and the transition connecting rod I, and will not be described in detail here.

[0032] In this embodiment, the linkage mechanism 3 further includes hollow shaft I 3012 and hollow shaft II 3022. Link I 301 or transition link I 3011 is hinged to the base 1 or upper support frame 2 via hollow shaft 3012, and link II 302 or transition link II 3022 is hinged to the base 1 or upper support frame 2 via hollow shaft II 3022. Any of the above-mentioned hinged connection structures can be selected to achieve the purpose of the utility model, and will not be elaborated further here. The elastic preload is applied by torsion spring I 5 and torsion spring II 6. Torsion spring I 5 passes through hollow shaft I 3012, with one end abutting against a designated position on hollow shaft I 3012 and the other end abutting against a corresponding fixed position. In a fixed position, the hinge refers to the rotational engagement between the hollow shaft (including hollow shaft I 3012 and hollow shaft II 3022) and the base or upper support frame, thereby enabling the connecting rod I 301, transition connecting rod I 3011, connecting rod II 302, and transition connecting rod II 3022 to form a hinge with the base and upper support frame. The hinge formed by the hollow shaft (including hollow shaft I 3012 and hollow shaft II 3022) can improve the strength of the hinged connection, ensure the durability of the structure, and at the same time provide a space for the torsion spring (including torsion spring I 5 and torsion spring II 6), ensuring that there is sufficient external functional space to accommodate other components, such as heating and ventilation components, which will not be elaborated here.

[0033] The "designed part" refers to a corresponding part designed within the hollow shaft I 3012 that can abut against one end of the torsion spring I 5, such as a slot or a protrusion. This is a general mechanical structure design and will not be elaborated further. Meanwhile, the corresponding "relatively fixed position" refers to the position corresponding to the other end of the torsion spring I 5 that does not participate in rotation, such as a corresponding position on the base or upper support frame, such as a slot or protrusion, used to abut against the other end of the torsion spring I 5. This is also a general mechanical structure design and will not be elaborated further. The torsion spring II 6 passes through the hollow shaft II 3022, with one end abutting against the designated part of the hollow shaft II 3022 and the other end abutting against the corresponding relatively fixed position. This structure is the same as the principle of the hollow shaft I 3012 and will not be elaborated further.

[0034] The elastic force of torsion spring I5 and / or torsion spring II6 is adjustable, making the elastic preload adjustable. There are various ways to adjust the elastic force. For example, one of torsion spring I5 and torsion spring II6 can be pressed against one end by a clamping block. The clamping block can be connected to a position that is fixed relative to the deformation of the linkage mechanism by means of a thread, such as a base or an upper support frame. This can achieve adjustable position and lockability. Alternatively, the position can be changed by rotating the clamping block and locked by a conventional mechanical structure. These are all applications of conventional mechanical structures and will not be elaborated here.

[0035] In this embodiment, both the base 1 and the upper support frame 2 are frame structures. A frame structure refers to a frame structure consisting of two sides, a front side, and a rear side, usually a rectangular or approximately rectangular structure, which will not be elaborated further here. The hollow shaft I 3012 is rotatably supported at the rear position of the upper support frame 2, which can be hinged to the rear or to the corresponding positions on both sides, which will not be elaborated further here. The upper end of the connecting rod I 301 is fixed to the hollow shaft I 3012, and the transition connecting rod I 3011 is hinged to the corresponding side 102 of the base 1, as shown in the figure. The two sides 102 of the base 1 are respectively provided with hinge ears, and the two transition connecting rods I 3011 are respectively hinged to the hinge ears of the two sides 102. The structure is simple and compact, and easy to install. The hollow shaft II 3022 is rotatably supported at the front position of the upper support frame 2, which can be hinged to the front or to the corresponding positions on both sides. The position of the connecting rod II 3021 is fixed to the hollow shaft II 3022. The fixing method can be an existing mechanical fixing connection method such as welding. The lower end of the connecting rod II 302 is hinged to the corresponding side of the base 1, as shown in the figure. The two sides 102 of the base 1 are respectively provided with hinge ears. The two connecting rods II 302 are respectively hinged to the hinge ears of the two sides 102. This is a common mechanical hinge structure, which will not be described in detail here. The damper 4 is installed between the front of the base 1 and the front of the upper support frame 2 to form damping between the base and the upper support frame. The damper is installed in a forward position, which makes the present invention have a large application space in the middle and rear and adapts to the needs of ergonomics. The damper is generally installed with the upper end hinged to the front of the upper support frame 2 and the lower end hinged to the front of the base 1. It needs to be matched with hinge ears and other structures, which will not be described in detail here.

[0036] In this embodiment, the rear side 201 of the upper support frame 2 is provided with a rear support lug 2021 for rotatably supporting the hollow shaft I. The torsion spring I5 passes through the hollow shaft I 3012, with one bearing end abutting against a limiting groove opened on the wall of the hollow shaft I 3012, and the other bearing end extending out of the hollow shaft I 3012 and abutting against the rear support lug. As shown in the figure, a strip-shaped groove, i.e. a limiting groove, is opened on the hollow shaft I 3012 along the axial direction. One bearing end of the torsion spring I5 is bent into a limiting part, and after passing through the hollow shaft I 3012, it is elastically fitted into the limiting groove, thereby forming a circumferential limiting. As shown in the figure, a flange is correspondingly formed on the rear support lug 2021, and the flange abuts against the other bearing end of the torsion spring I5, thereby realizing the application of rotational preload to the hollow shaft I 3012. This rotational preload makes the hollow shaft I 3012 have a tendency to drive the connecting rod 301 to swing upward, thereby forming a shock-absorbing structure.

[0037] The linkage mechanism 3 also includes a spring force adjustment mechanism 7 disposed on the upper support frame 2. The hollow shaft II 3022 is rotatably supported between the two sides 203 of the upper support frame 2. The torsion spring II 6 passes through the hollow shaft II 3022, and one bearing end abuts against a limiting groove opened on the wall of the hollow shaft II 3022. This structure is similar to the structure of the torsion spring I 5 installed on the hollow shaft I 3012, and will not be described in detail here. The other bearing end of the torsion spring II 6 extends out of the hollow shaft II and abuts against the adjustment end of the spring force adjustment mechanism. The structure of the spring force adjustment mechanism 7 adopts the existing mechanical structure, and the adjustment end is the aforementioned abutment block. As shown in the figure, the spring force adjustment mechanism 7 is installed on the corresponding side 203 of the upper support frame 2, including a knob 701 (generally manual, but can also be electric), a transmission mechanism 702, and an adjustment end 703. The adjustment end is generally strip-shaped. The transmission mechanism 702 has a rotating output shaft, and the adjustment end 702 is installed on the power output shaft and The axis of the driveable shaft swings, pressing against the other bearing end of the torsion spring II6 during the swing, thereby changing its position and adjusting the elastic force, ultimately adjusting the damping effect. This will not be elaborated further here. The transmission mechanism 702 generally adopts a mechanical structure that is driven to rotate and has self-locking capability, such as a ratchet and pawl structure. However, it needs to be equipped with a reverse release structure (such as a pin that can be inserted into different positions) and a worm gear structure with a self-locking angle. That is, a structure that transmits to the adjustment end through a knob and can make it swing. This can be achieved through a common mechanical structure, which will not be elaborated further here. As shown in the figure, the adjustment end is located inside the corresponding side 203 of the upper support frame 2. The other bearing end of the torsion spring II6 passes through the hollow shaft II3022, bends back, and passes through the arc-shaped through groove 2031 opened on the corresponding side 203 before pressing against the adjustment end 703. The overall structure is simple and compact. The adjustment end is located inside the side 203 to avoid interference and ensure the accuracy of adjustment.

[0038] In this embodiment, a hinge shaft 3023 is fixedly connected between the ends of the connecting rods 302 of the two sets of connecting rod assemblies II, and is hinged between the two sides 103 of the base 1 through the hinge shaft 3023. The two sides 103 are provided with hinge ears, which is a common structure of hinged connection and has high overall strength, which will not be described in detail here.

[0039] Structurally, the rear 201 of the upper support frame 2 is a shaft-shaped structure, which supports and hinges the rear lug of the hollow shaft I 3012. The lug is fixed on the rear 201 of the shaft-shaped structure and extends downward, ensuring the overall support strength. Meanwhile, the front 202 and the side 203 have a channel-shaped cross-section, similar to a channel steel structure, which supports the damper and other hinged structures, ensuring the overall strength. Further details are omitted here.

[0040] The positions on the base 1 that form a hinge connection with the hinge shaft 3023 and the transition link 3011 are integrally formed (sheet metal) to form hinge ears, thereby ensuring the load-bearing capacity of the hinge position and ensuring the stability of the entire frame.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
