Description

Technical Field

[0001] This invention relates to the field of vehicle parts technology, and in particular to a button-type ejection auxiliary mechanism for a seatbelt buckle assembly. Background Technology

[0002] In the automotive seatbelt buckle assembly, the push-button ejection mechanism is used to connect and disconnect the seatbelt buckle from the vehicle body fasteners. It typically consists of a connecting housing, a sliding plate, a buckle, a spring-loaded swing mechanism, an ejection mechanism, and a pressing mechanism. During operation, the sliding plate inserts into the connecting housing, the buckle engages with the connecting buckle, and the spring-loaded swing mechanism maintains the locking state. The pressing mechanism activates the unlocking mechanism to disengage the buckle, and the ejection mechanism pushes the sliding plate outwards.

[0003] After long-term use, the existing button-type ejection auxiliary mechanism is prone to fatigue in the elastic swing connection structure, resulting in a decrease in locking force. When the engagement is not in place, the ejection structure has a weak pushing effect on the sliding plate, which easily leads to a semi-locked state. There are few secondary fixing structures after locking, and the connection reliability decreases after the elastic component fails. When pressing to unlock, accidental contact can easily occur between the unlocking structure and the elastic sliding structure, affecting operational safety. To address this, we propose a button-type ejection auxiliary mechanism for a seat belt buckle assembly. Summary of the Invention

Detailed Implementation

[0022] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0023] Example: Figures 1 to 8As shown, a button-type ejection auxiliary mechanism for a seatbelt buckle assembly includes a connecting shell 111. The connecting shell 111 has an internal elastic swing connection structure, which includes a rotating pressing plate 112. A buckle 113 is fixedly installed on the bottom side of the pressing plate 112. A sliding plate 114 is slidably installed inside the connecting shell 111. A connecting buckle 115, compatible with the buckle 113, is fixedly installed on the side of the sliding plate 114. A first guide groove 116 is provided on the upper side of the connecting shell 111. An ejection structure is provided inside the connecting shell 111. A second connecting block 417 is fixedly installed on the upper side of the extrusion plate 112. A rotating second rotating column 542 is provided above the second connecting block 417. A second pressing block 513 is fixedly installed on one side of the second rotating column 542. A fixed swing plate 511 is provided at the other end of the second rotating column 542. A first unlocking structure for pressing the second connecting block 417 is provided on the bottom side of the second connecting block 417. A pressing structure is provided above the first unlocking structure. A fixing box 312 is fixedly installed inside the connecting shell 111. A fixing box 312 is provided inside the fixing box 312. The elastic sliding structure includes a second pressing block 313 slidably installed inside the fixed box 312. A first connecting block 315 is fixedly installed at one end of the second pressing block 313. A second unlocking structure is provided below the pressing structure. The elastic swing connection structure includes a connecting barrel 221 fixedly installed on the side of the connecting shell 111. A first rotating shaft 222 is fixedly installed on the side of the pressing plate 112 corresponding to the position of the connecting barrel 221. The first rotating shaft 222 is rotatably installed inside the connecting barrel 221. A first connecting block 315 is fixedly installed at one end of the first rotating shaft 222. A torsion spring 223 is fixedly installed on the inner side of the connecting barrel 221 at one end away from the first rotating shaft 222. The ejection structure includes two fixed barrels 211 fixedly installed on the inner side of the connecting shell 111. A sliding column 212 is slidably installed inside the fixed barrel 211. A first pressing block 214 is fixedly installed on one end of the two sliding columns 212. A first spring 213 is fixedly installed on the end of the sliding column 212 away from the first pressing block 214. The end of the first spring 213 away from the sliding column 212 is fixedly installed on the inner side of the fixed barrel 211.

[0024] More specifically, the first connecting block 315 is connected to the car seat, and the sliding plate 114 is connected to the car seat belt. During engagement, pulling the connecting shell 111 causes relative movement between the connecting shell 111 and the first connecting block 315, allowing the sliding plate 114 to slide into the connecting shell 111. The buckle 113 engages with the connecting buckle 115. After engagement, the elastic sliding structure drives the connecting shell 111 to reset. If the buckle 113 and connecting buckle 115 are not fully engaged, and the ejector structure's elasticity is insufficient to eject the sliding plate 114, the sliding plate 114 will detach from the connecting shell 111 during its reset movement. After full engagement, the elastic sliding structure presses against the swing plate 511. The swing plate 511, through the second rotating column 542, drives the second pressing block 513 to press against the second connecting block 417, thereby providing secondary fixation to the pressing plate 112. This prevents the elastic swing connecting structure that drives the pressing plate 112 from losing its elasticity due to a malfunction. After docking, the ejector structure causes the buckle 113 and the connecting buckle 115 to press against each other. When unlocking, the pressing structure is pressed down, which causes the second unlocking structure to push the elastic sliding structure to move. The elastic sliding structure separates from the swing plate 511. When the pressing structure continues to move downward, it triggers the first unlocking structure to push the second connecting block 417 upward. The second connecting block 417 drives the pressing plate 112 and the buckle 113 upward, causing the buckle 113 to separate from the connecting buckle 115. The ejector structure then pushes the connecting buckle 115 outward to complete the unlocking. The first torsion spring 223 provides torque to keep the pressing plate 112 always attached to the inside of the connecting shell 111. When the connecting buckle 115 is engaged, it presses the first pressing block 214. The first pressing block 214 drives the sliding column 212 to compress the first spring 213. When the buckle 113 separates from the connecting buckle 115, the first spring 213 recovers and pushes the sliding column 212 and the first pressing block 214 to press the connecting buckle 115.

[0025] like Figure 4 , Figure 7 and Figure 8As shown, the first unlocking structure includes a rotating third rotating column 552. A fourth pressing block 416 is fixedly installed on the side of the third rotating column 552 corresponding to the lower part of the second connecting block 417. A rotating plate 415 is fixedly installed on the other side of the third rotating column 552. A rotating swing block 411 is provided above the rotating plate 415. A first pressing block 414 is fixedly installed on the bottom side of the swing block 411 corresponding to the position of the rotating plate 415. A third connecting cover 551 is fixedly installed on the side of the connecting shell 111 corresponding to the position of the third rotating column 552. The third rotating column 552 is rotatably installed inside the third connecting cover 551. A sixth torsion spring 553 is fixedly installed on the end face of the third rotating column 552. The end of the sixth torsion spring 553 away from the third rotating column 552 is fixedly installed on the third connecting cover 551. Inside the shell 1, a third connecting block 422 is fixedly installed on the upper side of the connecting shell 111 corresponding to the position of the first guide groove 116. A first rotating hole 423 is opened on one side of the two third connecting blocks 422 corresponding to each other. A second rotating shaft 424 is rotatably installed inside the first rotating hole 423. A swing block 411 is fixedly installed on the side of the second rotating shaft 424. A second torsion spring 425 is fixedly installed on the end face of the second rotating shaft 424. The end of the second torsion spring 425 away from the second rotating shaft 424 is fixedly installed inside the first rotating hole 423. The pressing structure includes a connecting post 412 fixedly installed on the upper side of the swing block 411. The connecting post 412 extends upward through the first guide groove 116 to the top of the connecting shell 111. A connector 413 is fixedly installed on the upper side of the connecting post 412.

[0026] More specifically, pressing the connector 413 downward causes the connector 413 to drive the connecting post 412, the swing block 411, and the first pressing block 414 downward to press the rotating plate 415. The downward movement of the rotating plate 415 causes the third rotating post 552 to rotate inside the third connecting cover 551. The third rotating post 552 drives the fourth pressing block 416 upward to press the second connecting block 417. The second connecting block 417 drives the pressing plate 112 and the buckle 113 upward to separate from the connecting buckle 115 and unlock. The rotation of the third rotating post 552 causes the rotating plate 415 and the fourth pressing block 416 to rotate synchronously. The swing block 411 rotates through the second rotating shaft 424.

[0027] like Figure 5As shown, a fixing block 311 is fixedly installed on the bottom side of the fixing box 312. The side of the fixing block 311 away from the fixing box 312 is fixedly installed on the inner side of the connecting shell 111. The second pressing block 313 is a T-shaped block. A second spring 314 is fixedly installed on the side of the second pressing block 313 corresponding to the inside of the fixing box 312. One end of the second spring 314 is fixedly installed on the inner side of the fixing box 312. An adapter groove 316 is opened on the upper side of the fixing box 312. A second connecting block 4 is fixedly installed on the upper side of the second pressing block 313 corresponding to the position of the adapter groove 316. The third extrusion block 317 applies pressure. A second rotating column 542 is rotatably installed on the inner side of the connecting shell 111. A swing plate 511 is fixedly installed on the side of the second rotating hole 532 corresponding to the position of the third extrusion block 317. A second pressing block 513 is fixedly installed on the side of the second rotating column 542. A second guide groove 512 is opened on the side of the swing plate 511. The third extrusion block 317 extends through the second guide groove 512 to the top of the swing plate 511. A pushing block 318 is fixedly installed on the side of the third extrusion block 317 corresponding to the bottom of the swing plate 511.

[0028] More specifically, the second pressing block 313 slides inside the fixed box 312, the second spring 314 applies pressure to make the third pressing block 317 press the second connecting block 417, the pushing block 318 presses the swing plate 511, and the swing plate 511 applies force to the second pressing block 513 through the second rotating column 542, so that the second pressing block 513 presses the second connecting block 417, providing secondary fixing pressure.

[0029] like Figure 7 and Figure 8 As shown, specifically, the second unlocking structure includes two connecting rods 515 disposed below the connector 413. A fifth pressing block 514 is fixedly installed on the side of each connecting rod 515, and is disposed on the side of the third pressing block 317. The second unlocking structure also includes a baffle 421 fixedly installed on the upper side of the connecting shell 111 at a position corresponding to the first guide groove 116. Two first mounting grooves 531 are formed on the side of the baffle 421, and second rotating holes 532 are formed inside the first mounting grooves 531. The first rotating column 533 is rotatably installed inside each of the two rotating columns 533. A fourth torsion spring 534 is fixedly installed at one end of the first rotating column 533. The end of the fourth torsion spring 534 away from the first rotating column 533 is fixedly installed inside the second rotating hole 532. The sides of the two first rotating columns 533 are fixedly connected to the connecting rod 515. A second connecting cover 541 is fixedly installed on the side of the connecting shell 111. The second rotating column 542 is rotatably installed inside the second connecting cover 541. A fifth torsion spring 543 is fixedly installed on the end face of the second rotating column 542. One end of the fifth torsion spring 543 is fixedly installed inside the second connecting cover 541.

[0030] More specifically, the connector 413 presses down on the connecting rod 515, and the connecting rod 515 drives the fifth pressing block 514 to press the upper side of the third pressing block 317. In the initial state, the downward pressing of the connector 413 is increased with resistance to avoid accidental contact. The second rotating column 542 rotates inside the second connecting cover 541, and the fifth torsion spring 543 provides a restoring force.

[0031] Working principle: The first connecting block 315 is connected to the car seat, and the sliding plate 114 is connected to the car seat belt. When engaged, pulling the connecting shell 111 causes relative movement between the connecting shell 111 and the first connecting block 315. The sliding plate 114 slides into the interior of the connecting shell 111, and the connecting buckle 115 pushes the first pressing block 214, causing the sliding column 212 to compress the first spring 213. At the same time, the buckle 113 engages with the connecting buckle 115. The first torsion spring 223 keeps the pressing plate 112 attached to the inside of the connecting shell 111 through the first rotating shaft 222. The second spring 314 inside 312 pushes the second pressing block 313, causing the pushing block 318 on the side of the third pressing block 317 to press the swing plate 511. The swing plate 511 drives the second pressing block 513 to press the second connecting block 417 through the second rotating column 542, forming a secondary fixation for the pressing plate 112. If the buckle 113 and the connecting buckle 115 are not fully engaged and the spring force of the ejection structure is insufficient to push out the sliding plate 114, the sliding plate 114 will disengage from the connecting shell 111 when the connecting shell 111 is reset. When unlocking, press the connecting head 413 downwards. The connecting column 412 drives the swing block 411 to swing around the second rotating shaft 424. The connecting head 413 first squeezes the connecting rod 515. The connecting rod 515 drives the fifth squeezing block 514 to push the third squeezing block 317, causing the second squeezing block 313 to compress the second spring 314. The pushing block 318 separates from the swing plate 511 and continues to press down on the connecting head 413. The first pressing block 414 on the bottom side of the swing block 411 presses the rotating plate 415. The third rotating column 552 rotates inside the third connecting cover 551 and drives the fourth squeezing block 416 to press the second connecting head 415 upward. Connecting block 417, the second connecting block 417 drives the pressing plate 112 and the buckle 113 to move upward, so that the buckle 113 separates from the connecting buckle 115. At this time, the first spring 213 returns to its original state, pushes the sliding column 212 and the first pressing block 214, pushes out the connecting buckle 115 and the sliding plate 114, and completes the unlocking. After the connecting head 413 is released, the second torsion spring 425, the sixth torsion spring 553, the fourth torsion spring 534 and the fifth torsion spring 543 respectively drive the swing block 411, the third rotating column 552, the first rotating column 533 and the second rotating column 542 to reset.
