Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a multi-dimensional linkage adjustable automotive seat suspension. Background Technology

[0002] A car seat suspension is an elastic buffer mechanism installed between the car seat and the vehicle chassis. Its core function is to absorb vibrations and impacts during vehicle operation through mechanical or hydraulic structures, reducing the bumps transmitted to the seat and improving ride comfort. The core components of a car seat suspension mainly include elastic elements, damping elements, and connecting elements. When a vehicle travels on uneven surfaces such as gravel roads or speed bumps, the vehicle body will generate high-frequency or low-frequency vibrations. The seat suspension, through the cooperation of elastic elements and dampers, can filter out some of these vibrations, reducing the bumps transmitted to the body and preventing fatigue in the lower back and hips caused by prolonged sitting.

[0003] However, existing seat suspensions can only achieve vertical shock absorption, with limited adjustment dimensions. They cannot simultaneously adapt to multi-dimensional dynamic situations such as pitching forward and backward during sudden braking and acceleration, and lateral tilting when turning. This results in a mismatch between human inertia and seat posture, leading to insufficient comfort and safety.

[0004] To address this, we propose a multi-dimensional linkage adjustable car seat suspension, designed to enable the seat to simultaneously adjust its posture in multiple dimensions, such as pitch, roll, and tilt, under the action of the adjustment components when the vehicle is under sudden braking, acceleration, or turning, thus conforming to the centrifugal force requirements of the human body.

[0008] The adjustment assembly includes a pair of first fixed seats, a pair of second fixed seats, and four spherical seats mounted on the top surface of the base plate. The pair of first fixed seats are respectively mounted on the top surface of the pair of sliders, and the pair of second fixed seats are respectively mounted on the top surface of the base plate away from the slide groove. The pair of first fixed seats and the pair of second fixed seats are all provided with grooves inside, and the four spherical seats rotate in the four grooves respectively.

[0009] The shock-absorbing component is installed on the top surface of the spherical seat, and the shock-absorbing component is used for shock absorption and buffering.

[0010] The mounting assembly is installed on the top surface of the shock-absorbing assembly and is used for mounting and connecting with the seat frame.

[0011] Furthermore, the damping assembly includes a sleeve, a piston, a piston rod, and a spring mounted on the upper ends of the four spherical seats. The sleeve has an outer cavity and an inner cavity from the outside to the inside. The piston slides inside the inner cavity. The top surface of the sleeve has a sliding hole. The piston rod slides inside the sliding hole. The bottom end of the piston rod is fixedly connected to the top surface of the piston. The spring is installed inside the inner cavity. The two ends of the spring are fixedly connected to the top surface of the piston and the inner top surface of the inner cavity, respectively. The spring is sleeved on the outside of the piston rod. The side surface of the inner cavity has several first through holes. The bottom surface of the inner cavity has several second through holes. Both the inner cavity and the outer cavity are filled with damping oil.

[0012] Furthermore, a first connector and a second connector are respectively installed at the bottom end of the sleeve and the upper end of the plug rod. A first connecting seat and a second connecting seat are respectively bolted to the outside of the first connector and the second connecting seat. The bottom end of the first connecting seat is fixedly connected to the upper end of the spherical seat.

[0013] Furthermore, the mounting assembly includes a seat mounting plate, the bottom four corners of which are respectively hinged to the upper ends of four second connecting seats via hinge seats;

Rotating spherical seats rotate within the grooves of both the first and second fixed seats. When the vehicle brakes suddenly, accelerates, or tilts during a turn, the seat can simultaneously achieve multi-dimensional posture adjustments such as pitching forward and backward, and tilting left and right under the action of the adjustment components, conforming to the centrifugal force requirements of the human body; during emergency braking or acceleration, the human body, due to inertia... The body generates a forward or backward force, pushing the seat to slide along the base plate groove via the slider of the support component. During emergency braking, the slider slides backward, and during acceleration, it slides forward. At the same time, the spherical seat of the adjustment component rotates in the groove of the fixed seat as the slider moves, causing the shock absorption component to tilt, making the seat tilt backward or forward as a whole, dispersing the impact force. When turning left or right, the human body generates a lateral force to the right or left due to centrifugal force, pushing the spherical seats on both sides of the seat to rotate differently in the groove. When turning left, the right spherical seat rotates downward and the left spherical seat rotates upward, and vice versa when turning right, the right spherical seat rotates upward and the left spherical seat rotates downward. At the same time, it causes the shock absorption components on both sides to form a stiffness difference, counteracting the lateral inertial force and improving riding stability.

[0028] Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concepts disclosed in this utility model.

[0029] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention.

[0030] Reference manual attached Figures 1 to 5 This illustrates the structure of a multi-dimensional linkage adjustable car seat suspension provided by an embodiment of the present invention.

[0031] This utility model provides a multi-dimensional linkage adjustable car seat suspension structure, including: a support component 1, an adjustment component 2, a shock absorption component 3, and a mounting component 4.

[0032] The support assembly 1 includes a base plate 11 mounted on the vehicle floor and a pair of sliders 13. A pair of grooves 12 are provided on one side of the top surface of the base plate 11, and the pair of sliders 13 slide inside the pair of grooves 12 respectively.

[0033] The adjustment assembly 2 includes a pair of first fixed seats 21, a pair of second fixed seats 22 and four spherical seats 24 installed on the top surface of the base plate 11. The pair of first fixed seats 21 are respectively installed on the top surface of a pair of sliders 13, and the pair of second fixed seats 22 are respectively installed on the top surface of the base plate 11 away from the slide groove 12. The interior of the pair of first fixed seats 21 and the pair of second fixed seats 22 is provided with grooves 23, and the four spherical seats 24 rotate in the four grooves 23 respectively.

[0034] The shock absorber 3 is installed on the top surface of the spherical seat 24 and is used for shock absorption and buffering.

[0035] Mounting component 4 is installed on the top surface of shock absorber component 3 and is used for installation and connection with seat frame.

[0036] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following:

[0037] In this embodiment of the invention, through the arrangement of sliders 13 and grooves 12, a pair of sliders 13 can slide inside a pair of grooves 12 respectively, providing the seat with a degree of freedom for adjustment in the fore-and-aft direction, that is, the sliders 13 slide backward during emergency braking and slide forward during rapid acceleration. A pair of first fixed seats 21 are mounted on a pair of sliders 13, while a pair of second fixed seats 22 are mounted on the top surface of the base and are respectively opposite to the pair of first fixed seats 21. Rotatable spherical seats 24 rotate within the grooves 23 of both the first fixed seats 21 and the second fixed seats 22. When the vehicle brakes suddenly, accelerates, or tilts during a turn, the seat can simultaneously achieve multi-dimensional posture adjustments such as pitching forward and backward, and tilting left and right under the action of the adjustment component 2, conforming to the centrifugal force requirements of the human body. During sudden braking or acceleration, the human body generates a forward or backward force due to inertia, pushing the seat to slide along the groove 12 of the base plate 11 via the slider 13 of the support component 1. During sudden braking, the slider 13 slides backward, and during acceleration, it slides forward. At the same time, the spherical seat 24 of the adjustment component 2 rotates within the groove 23 of the fixed seat as the slider 13 moves, causing the shock absorption component 3 to tilt, making the seat tilt backward or forward as a whole, dispersing the impact force. When turning left or right, the human body generates a lateral force to the right or left due to centrifugal force, pushing the spherical seats 24 on both sides of the seat to rotate differentially within the groove 23. When turning left, the right spherical seat 24 rotates downward and the left spherical seat 24 rotates upward, and vice versa. At the same time, this causes the shock absorption components 3 on both sides to form a stiffness difference, counteracting the lateral inertial force and improving riding stability.

[0038] In one possible implementation, the damping assembly 3 includes a sleeve 31, a piston 32, a stopper rod 33, and a spring 34 mounted on the upper ends of four spherical seats 24. The sleeve 31 has an outer cavity and an inner cavity from the outside to the inside. The piston 32 slides inside the inner cavity. The top surface of the sleeve 31 has a sliding hole. The stopper rod 33 slides inside the sliding hole. The bottom end of the stopper rod 33 is fixedly connected to the top surface of the piston 32. The spring 34 is installed inside the inner cavity. The two ends of the spring 34 are fixedly connected to the top surface of the piston 32 and the inner top surface of the inner cavity, respectively. The spring 34 is sleeved on the outside of the stopper rod 33. The side surface of the inner cavity has several first through holes, and the bottom surface of the inner cavity has several second through holes. Both the inner cavity and the outer cavity are filled with damping oil.

[0039] In this embodiment of the utility model, when the vehicle body vibrates, it drives the bottom plate 11 to move up and down. The bottom plate 11 drives the seat mounting plate 41 to move through the adjustment component 2, thereby causing the piston rod 33 and piston 32 to slide in the inner cavity. The piston 32 squeezes the damping oil, and the damping oil flows between the outer cavity and the inner cavity through the first through hole and the second through hole. The viscosity of the damping oil generates resistance, which converts the vibration energy into heat energy and other forms of energy to be consumed. During the movement of the piston 32, the elasticity of the spring 34 itself can also absorb some vibration energy and assist in shock absorption.

[0040] In one possible implementation, a first connector 35 and a second connector are respectively installed at the bottom end of the sleeve 31 and the upper end of the plug rod 33. A first connector 36 and a second connector are respectively bolted to the outside of the first connector 35 and the second connector. The bottom end of the first connector 36 is fixedly connected to the upper end of the ball seat 24.

[0041] In this embodiment of the invention, the first connector 35 and the first connector 36, and the second connector and the second connector 36 are rigidly connected by bolts to ensure effective force transmission. Simultaneously, the bolted connection facilitates the individual replacement of damaged components. When the shock absorber assembly 3 fails, the bolts at the first connector 35 and the second connector can be unscrewed with a screwdriver, allowing direct replacement of the faulty shock absorber assembly 3 without disassembling the entire seat suspension.

[0042] In one possible implementation, the mounting assembly 4 includes a seat mounting plate 41, the bottom four corners of which are respectively hinged to the upper ends of four second connecting seats via hinge seats.

[0043] Mounting assembly 4 also includes a second magnetic shielding sleeve 42 and a second magnetic plate 43. A second mounting groove is provided at the center of the seat mounting plate 41. The second magnetic shielding sleeve 42 is installed inside the second mounting groove, and the second magnetic plate 43 is installed inside the second magnetic shielding sleeve 42.

[0044] In this embodiment of the invention, the seat mounting plate 41 allows users to easily align and pre-drill holes during its production process, facilitating the subsequent installation of the seat frame onto the seat mounting plate 41 using bolts and fasteners. The second magnetic shielding sleeve 42 prevents magnetic leakage from the second magnetic plate 43, thus avoiding interference with the operation of in-vehicle electronic equipment.

[0045] In one possible implementation, the support assembly 1 further includes a first magnetic shielding sleeve 14 and a first magnetic plate 15. A first mounting groove is provided at the center of the bottom plate 11. The first magnetic shielding sleeve 14 is installed inside the first mounting groove, and the first magnetic plate 15 is installed inside the first magnetic shielding sleeve 14.

[0046] In this embodiment of the utility model, the first magnetic shielding sleeve 14 is provided to prevent the magnetic force of the first magnetic plate 15 from leaking out and interfering with the operation of electronic equipment in the vehicle.

[0047] In one possible implementation, the first magnetic plate 15 and the second magnetic plate 43 are magnetically repelled.

[0048] In this embodiment of the utility model, the first magnetic plate 15 and the second magnetic plate 43 are magnetically repulsive, thereby forming a non-contact elastic support. When the vehicle vibrates, the first magnetic plate 15 and the second magnetic plate 43 approach each other under the action of vibration. The magnetic repulsion force can pre-counteract part of the vibration energy, reduce the compression stroke of the spring 34, and thus extend the life of the spring 34.

[0049] In one possible implementation, the first fixing seat 21, the second fixing seat 22, the spherical seat 24, the first connecting seat 36, the first connector 35, the second connector and the second connecting seat are all made of metal steel.

[0050] In this embodiment of the utility model, by setting the first fixing seat 21, the second fixing seat 22, the spherical seat 24, the first connecting seat 36, the first connecting head 35, the second connecting head and the second connecting seat to be made of metal steel, the strength of the first fixing seat 21, the second fixing seat 22, the spherical seat 24, the first connecting seat 36, the first connecting head 35, the second connecting head and the second connecting seat is improved.

[0051] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the preferred embodiments; however, those skilled in the art can fully understand this utility model without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, and not to limit it.
