Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive seat accessories technology, specifically to a seat cushion adjuster connecting plate. Background Technology
[0002] The seat cushion adjuster connecting plate is an important connecting component in automotive seat parts. It is mainly used to connect the seat cushion adjuster to other structural parts of the seat, such as the seat frame. Its function is to ensure the seat cushion angle can be flexibly adjusted while maintaining the stability and strength of the entire seat structure.
[0003] When a vehicle collides or experiences a significant external impact, the seat adjuster connecting plate may deform or even break due to insufficient strength. In some rear-end collisions, the passenger's body is thrown forward due to inertia, putting considerable pressure on the seat cushion. If the seat adjuster connecting plate cannot withstand this sudden and enormous impact force, it will be damaged, affecting the normal use of the seat and even threatening the passenger's safety.
[0004] In the prior art, the seat adjuster connecting plate experiences stress concentration when subjected to force, leading to premature fatigue and damage of local materials. The contact area between the seat adjuster connecting plate and the connecting shaft, as well as the connection point between the seat adjuster connecting plate and other components, are often areas of stress concentration, which reduces the service life of the seat adjuster connecting plate. Utility Model Content

[0023] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.
[0024] Figure 1 and Figure 2 The structure of a seat adjuster connecting plate 100 according to an embodiment of the present invention is shown. The seat adjuster connecting plate 100 may include: a seat adjuster connecting plate body 1, a connecting shaft assembly fixed to the top region of the seat adjuster connecting plate body 1, the connecting shaft assembly including a connecting shaft 3 fixed to the seat adjuster connecting plate body 1, the connecting shaft 3 facilitating rotation of the seat adjuster connecting plate body 1, a first reinforcing rib 4 surrounding the connecting shaft 3, and a buffer assembly 6 disposed between the first reinforcing rib 4 and the connecting shaft 3, combined with... Figure 4As shown, the buffer assembly 6 may include a plurality of dispersion channels 5 located between the first reinforcing rib 4 and the connecting shaft 3, and a first spring 51 and a damper (not shown in the figure) fixed in the dispersion channels 5. The two ends of the first spring 51 and the damper are respectively fixedly connected to two opposite inner wall surfaces of the dispersion channels 5, and the first spring 51 is sleeved on the outside of the damper.
[0025] In the seat adjuster connecting plate 100 of this utility model embodiment, since the connecting shaft 3 is a key part of the seat adjuster connecting plate and bears a large force, by setting a first reinforcing rib 4 near this position, the concentrated force transmitted from the adjuster can be effectively resisted. The setting of the first reinforcing rib 4 can change the stress distribution, dispersing the high stress originally concentrated near the connecting shaft 3 to the first reinforcing rib 4 and a more distant area. By setting a buffer component 6 on the seat adjuster connecting plate body 1, during long-term use, when the seat angle is frequently adjusted, the material at the connecting shaft 3 will be repeatedly subjected to force. The dispersion groove 5 can change the force transmission path when the seat adjuster is working, so that the stress can be more evenly distributed in other areas of the seat adjuster connecting plate body 1. During vehicle driving, if encountering bumps or sudden impacts, the connecting shaft 3 will be subjected to a large instantaneous force, and the dispersion groove 5 can play a certain role in mitigating the impact. The through groove acts as a shock absorber, absorbing some of the impact force. This is because the presence of the through groove changes the stiffness distribution of the structure, allowing the structure around the connecting shaft 3 to have a certain elastic deformation space when subjected to impact, dispersing the impact force to the entire seat adjuster connecting plate body 1, thereby reducing the direct impact on the connecting shaft 3. The first spring 51 and the damper are set inside the dispersion through groove 5. The two ends of the first spring 51 and the damper are respectively fixedly connected to the two inner walls of the dispersion through groove 5. The first spring 51 is sleeved on the outside of the damper. When the seat adjuster connecting plate 100 is impacted by an external force, the first spring 51 will first undergo elastic deformation, absorbing and storing some of the impact energy, thereby reducing the impact force transmitted to the connecting shaft 3 and other components. The damper will further consume the impact energy by generating a damping force opposite to the direction of movement during the deformation of the first spring 51, making the impact force more effectively reduced and preventing the connecting shaft 3 and other components from being damaged by excessive impact force instantaneously.
[0026] In such Figure 1 In the preferred embodiment shown, in order to further improve the buffering effect on the connecting shaft 3, the first reinforcing rib 4 can be formed into a ring shape, and each dispersed through groove 5 can be arranged at equal intervals around the first reinforcing rib 4 and the connecting shaft 3.
[0027] In such Figure 1 He Ru Figure 4In the preferred embodiment shown, the top region of the seat adjuster connecting plate body 1 may have mounting holes and a composite plate 14 fixed within the mounting holes. A connecting shaft 3 is fixed at the center of the composite plate 14, a first reinforcing rib 4 is fixed at the planar edge of the composite plate 14, and a dispersion groove 5 is formed in the region of the composite plate 14 between the first reinforcing rib 4 and the connecting shaft 3. This arrangement allows the composite plate 14, the first reinforcing rib 4, the dispersion groove 5, and the connecting shaft 3 to form a single module, facilitating its fixed installation with the mounting holes on the seat adjuster connecting plate body 1. By selecting an appropriate material for the composite plate 14, giving it a certain degree of elasticity, its cushioning effect can be further improved.
[0028] According to this utility model, in such Figure 1 In the preferred embodiment shown, the seat adjuster connecting plate body 1 may also be provided with a core reinforcement component 7 located below the first reinforcing rib 4. The core reinforcement component 7 may include at least one X-shaped groove and an X-shaped reinforcing rib connected to the inner wall of the X-shaped groove. In this embodiment, the X-shaped reinforcing rib can effectively disperse the stress in the stress concentration area. The presence of the X-shaped reinforcing rib can disperse these concentrated stresses to the surrounding area along its oblique line. When adjusting the seat angle, torque and forces in multiple directions are generated. The X-shaped reinforcing rib can effectively resist bending forces in two mutually perpendicular directions in the plane, thereby enhancing the rigidity of the seat adjuster connecting plate 100 under complex stress conditions.
[0029] Preferably, such as Figure 1 As shown, the core reinforcement component 7 can be set between the first reinforcing rib 4 and the transverse centerline of the seat cushion angle adjuster connecting plate body 1.
[0030] Preferably, the included angle α of the X-shaped groove toward the first reinforcing rib 4 can be in the range of 90° to 120°.
[0031] According to this utility model, in such Figure 1 and Figure 3In the preferred embodiment shown, the lower region of the seat adjuster connecting plate body 1 may also have at least two rivet holes 2 spaced apart. Adjacent rivet holes 2 are connected by a movable plate assembly 20. Slide grooves (not shown) are provided on the sidewalls of adjacent rivet holes 2 that are close to each other and opposite to each other. The movable plate assembly 20 may include a slider 9 slidably connected to the slide groove, a second spring 11 connected between adjacent sliders 9, and a storage sealing box 10 located between adjacent sliders 9. The storage sealing box 10 is simultaneously connected to adjacent sliders 9 through a connecting pipe 12. A liquid reservoir (not shown) storing anaerobic adhesive is provided inside the storage sealing box 10. A through hole 91 connected to the connecting pipe 12 may be formed on the slider 9. The storage sealing box 10 is configured such that when the slider 9 is compressed by an external force and impacts the storage sealing box 10, the liquid reservoir inside the storage sealing box 10 can be damaged.
[0032] In this embodiment, by setting up a slider 9, the slider 9 can be squeezed inward after the rivet enters. By setting up a connecting pipe 12, the medium can flow. When the rivet is loosened, the rivet will shake and hit the slider 9 to slide along the groove, thereby compressing the second spring 11. When the slider 9 hits the storage sealing box 10, the liquid storage bladder inside it is damaged, so that the anaerobic glue inside it flows out and fills the gap around the rivet through the connecting pipe 12. After these substances solidify, they can increase the rigidity and stability of the connection.
[0033] In another preferred embodiment, with Figure 3 The difference in the illustrated embodiment is that the storage sealing box 10 can be directly connected to the adjacent slider simultaneously via the elastic telescopic tube. Since the elastic telescopic tube serves the functions of both the second spring 11 and the connecting tube 12, it can also achieve the same result. Figure 3 The function of the active panel assembly 20 in the illustrated embodiment.
[0034] In such Figure 3 In the preferred embodiment shown, a locking pin 13 may be connected to the storage sealing box 10. When the slider 9 is compressed by an external force to the second spring 11 and strikes the locking pin 13, the locking pin 13 punctures the liquid storage bladder.
[0035] In such Figure 1 In the preferred embodiment shown, the lower region of the seat adjuster connecting plate body 1 may have two rivet holes 2 spaced apart. The first rivet hole 2 is located at the front end of the lower region of the seat adjuster connecting plate body 1, and the second rivet hole is located between the first rivet hole and the core reinforcement component 7. This arrangement allows the two rivet holes 2, the core reinforcement component 7, and the connecting shaft assembly to be distributed in different regions of the seat adjuster connecting plate body 1, which helps to further improve the shock absorption effect and thus better eliminate stress concentration.
[0036] According to this utility model, such as Figure 1 and Figure 2 As shown, a second reinforcing rib 8 may also be provided on the front end face of the lower region of the seat cushion adjuster connecting plate body 1. During the operation of the seat cushion adjuster, the connecting end face will be subjected to forces from different directions, such as the tension or pressure generated when the passenger adjusts the seat angle. The provision of the second reinforcing rib 8 can significantly enhance the strength of the end face, enabling it to better withstand these forces.
[0037] The working principle of the seat cushion adjuster connecting plate 100 in this embodiment of the utility model is as follows: When the seat cushion adjuster is impacted by an external force, the first spring 51 in the dispersion groove 5 first undergoes elastic deformation, absorbing and storing a portion of the impact energy, reducing the impact force transmitted to the connecting shaft 3 and other components. At the same time, the damper generates a damping force opposite to the direction of motion during the deformation of the first spring 51, further consuming the impact energy, reducing the impact force, and preventing damage to components such as the connecting shaft 3. During long-term use, the seat angle is frequently adjusted, and the material at the connecting shaft 3 is repeatedly subjected to force. The dispersion groove 5 can change the force transmission path, so that the stress is evenly distributed in other areas of the seat cushion adjuster connecting plate 100. The annular first reinforcing rib 4 can disperse the high stress near the connecting shaft 3 to the first reinforcing rib 4 or to a more distant area. X-shaped reinforcing ribs can disperse the stress in the stress concentration area to the surrounding area along the diagonal lines. When the rivet in the rivet hole 2 loosens, the rivet hits the slider 9, and the slider 9 hits the jack 13, causing the liquid storage bladder stored in the storage sealing box 10 to be punctured. The anaerobic adhesive inside flows out and fills the gap around the rivet through the connecting tube 12. After curing, it increases the rigidity and stability of the connection.
