[0064] Currently, seatbelt buckles are equipped with Hall effect sensors that sense the lock tongue, providing a power-off warning to alert passengers that the lock tongue is correctly inserted. However, due to inaccurate assembly and placement of the Hall effect sensors and lock tongue in existing seatbelt buckles, sensing instability often occurs, affecting the accuracy of these warnings.

[0065] Based on this, the present application provides a wiring harness switch installed in a seat belt buckle, and the wiring harness switch includes: a base, a cover plate, an elastic sliding component, a limiting connection structure, a first power-on component and a second power-on component. The base is provided with a limiting snap-fit structure, a guide structure and a limiting accommodation structure.

The first and second energizing components are mounted in the position-limiting accommodation structure, and the abutting end of the first energizing component is connected to the elastic sliding component, while the abutting end of the second energizing component can be attached to or separated from the first energizing component. When the lock tongue of the lock buckle is not inserted into the lock buckle, the elastic sliding component is not driven, and the elastic sliding component has an elastic force toward the bottom of the lock buckle. The abutting end of the first energizing component is connected to the elastic sliding component, and the abutting end of the second energizing component is attached to the first energizing component to form a circuit path state.

[0068] like Figures 1 to 9 As shown, the present application provides a wiring harness switch for installation in a seat belt buckle. The wiring harness switch comprises: a base 1, a cover plate 2, an elastic sliding assembly 3, a position-limiting connection structure 4, a first energizing assembly 5, and a second energizing assembly 6. The base 1 is provided with a position-limiting clamping structure 11, a guide structure 12, and a position-limiting accommodating structure 13. The position-limiting clamping structure 11 is disposed on a first sidewall 15 of the base 1 and is connected to the buckle's lock body via the position-limiting clamping structure 11. The guide structure 12 is disposed on a side of the base 1 facing the bottom of the buckle. The position-limiting accommodating structure 13 is disposed within the base 1. The position-limiting connection structure 4 is disposed between the cover plate 2 and a second sidewall 16 of the base 1. The cover plate 2 is connected to the base 1 via the position-limiting connection structure 4, and the position-limiting accommodating structure 13 is mounted within the base 1. The elastic sliding assembly 3 is movably disposed in the guide structure 12 along a first direction. The elastic sliding assembly 3 can abut against the buckle's ejection block 7, allowing it to move within the guide structure 12 under the force of the ejection block 7. The first energizing component 5 and the second energizing component 6 are installed in the position-limiting accommodating structure 13, and the abutting end of the first energizing component 5 is connected to the elastic sliding component 3, and the abutting end of the second energizing component 6 can be attached to or separated from the first energizing component 5. When the lock tongue of the lock buckle is not inserted into the lock buckle, the elastic sliding component 3 is not driven, and the elastic sliding component 3 has an elastic force toward the bottom of the lock buckle. The abutting end of the first energizing component 5 is connected to the elastic sliding component 3, and the abutting end of the second energizing component 6 is attached to the first energizing component 5 to form a circuit path state. When the lock tongue of the lock buckle is inserted into the lock buckle, the elastic sliding component 3 is driven to move away from the bottom of the lock buckle. The elastic sliding component 3 is compressed and has a restoring elastic force. The abutting end of the first energizing component 5 connected to the elastic sliding component 3 is driven, causing the abutting end of the second energizing component 6 to separate from the first energizing component 5, forming a circuit disconnection state.

[0069] Specifically, in this embodiment, the base 1 includes a base body, a position-limiting snap-fitting structure 11, a guide structure 12, and a position-limiting accommodating structure 13, wherein the base body is an irregular square structure having a first side wall 15 (not labeled), a second side wall 16, a third side wall (not labeled), and a fourth side wall 17, wherein the first side wall 15 and the second side wall 16 are arranged opposite to each other, and the third side wall and the fourth side wall 17 are arranged opposite to each other. The first side wall 15, the third side wall, and the fourth side wall 17 together form the main part of the base body, and the cover plate 2 is mounted on the second side wall 16. The position-limiting snap-fitting structure 11 is provided on the first side wall 15 of the base 1, and the base 1 is connected to the lock body of the lock buckle through the position-limiting snap-fitting structure 11. Specifically, in one example, the position-limiting snap-fitting structure 11 includes: a position-limiting card body 111, a position-limiting card slot 112, and a position-limiting card hook 113. The position-limiting card body 111 protrudes from the middle of the first side wall 15 of the base 1. The position-limiting card body 111 is snapped into the lock hole of the lock body of the lock buckle to connect the base 1 to the lock body. In one example, the position-limiting card body 111 is in the shape of a square cylinder, and the square cylinder-shaped position-limiting card body 111 is perpendicular to the first side wall 15 of the base 1. Correspondingly, the lock hole of the lock body of the lock buckle is square and is set in the middle of the side wall of the lock buckle. The position-limiting card body 111 is snapped into the lock hole of the lock body of the lock buckle. When the position-limiting card body 111 is snapped into the lock hole of the lock body of the lock buckle, the freedom of the base 1 in the front, back, up, and down directions relative to the lock buckle can be limited. A limiting slot 112 is provided at the rear end of the first side wall 15 of the base 1, with its opening facing the front end of the base 1. The limiting slot 112 is secured to the end of the lock body of the latch to limit the base 1's freedom of movement relative to the front end of the lock body. In one example, the limiting slot 112 is arranged in a stepped manner and includes an integrally formed first and second slot end surfaces. The first slot end surface is perpendicular to the first side wall 15 of the base 1, while the second slot end surface is parallel to the first side wall 15 of the base 1. A limiting hook 113 protrudes from the first side wall 15 of the base 1 and is secured to the lock body of the latch to limit the base 1's freedom of movement relative to the side wall away from the lock body. In one example, the limiting hook 113 is provided on the third side wall and extends beyond the first side wall 15. The limiting hook 113 includes an extension arm and a hook, with the hook being integrally formed at the end of the extension arm.

[0070] The interior of the base 1 is provided with an open groove relative to the second side wall 16 of the base 1, and the limiting and accommodating structure 13 is provided in the open groove. In this embodiment, the limiting and accommodating structure 13 includes: a separating rib 131, a first limiting body 132, and a second limiting body 133. The separating rib 131 is provided in the middle part of the interior of the base 1, extending along the length direction (third direction) of the base 1. The separating rib 131 separates the respective connection ends of the first power-carrying component 5 and the second power-carrying component 6. The end of the separating rib 131 close to the abutting end of the first power-carrying component 5 is provided in an inclined shape so that the respective abutting ends of the first power-carrying component 5 and the second power-carrying component 6 can be brought together and abutted. In one example, the separating rib 131 is provided in an irregular long strip shape, and the end close to the abutting end of the first power-carrying component 5 is provided in a slender strip inclined shape. The inclined end of the slender strip can enable the respective abutting ends of the first power-carrying component 5 and the second power-carrying component 6 to be brought together and abutted. The end thereof close to the connection end of the first power-carrying component 5 is configured as a thick long strip. The thick long strip end can separate the respective connection ends of the first power-carrying component 5 and the second power-carrying component 6 to prevent the respective connection ends of the first power-carrying component 5 and the second power-carrying component 6 from contacting to form a passage, and further, prevent the crimping areas of the first power-carrying component 5 and the second power-carrying component 6 from contacting to form a passage. The thick long strip end and the thin long strip inclined end are connected by a cross-shaped connecting rib in the middle. The first limiting body 132 and the second limiting body 133 are relatively arranged on both sides of the separating rib 131 in the first direction. The first direction refers to the direction relative to the third side wall and the fourth side wall 17, and correspondingly, the second direction refers to the direction relative to the second side wall 16 and the first side wall 15. The first limiting body 132 and the second limiting body 133 respectively form a first accommodating gap 134 and a second accommodating gap 135 relative to the separating rib 131. The first power-carrying component 5 is installed in the first accommodating gap 134, and the second power-carrying component 6 is installed in the second accommodating gap 135. In one example, in the second direction, the protrusion height of the first limiting body 132 and the second limiting body 133 is equal to the protrusion height of the middle part of the dividing rib 131, and is lower than the protrusion height at both ends of the dividing rib 131, so that the middle part of the dividing rib 131 and the first limiting body 132 and the second limiting body 133 are concave compared to the two ends of the dividing rib 131.

[0071] The guide structure 12 is arranged on the side of the base 1 facing the bottom of the lock, that is, the guide structure 12 is arranged on the fourth side wall 17 of the base 1. Specifically, the guide structure 12 includes a guide window 121 and a guide rib 122. Among them, the guide window 121 is arranged on the side of the base 1 facing the bottom of the lock, that is, the guide window 121 is arranged through the first side of the base 1 and is located at the front end of the base 1 (specifically, the guide window 121 is located at the front end of the first side of the base 1). The main body 311 of the slider 31 (described below) is accommodated in the guide window 121. In one example, the cross-section of the guide window 121 in the second direction is directional, that is, the guide window 121 has a square opening. The guide rib 122 is arranged on the wall of the guide window 121 along the first direction, and is arranged opposite to the guide portion 313 (described below) of the slider 31, and the guide portion 313 is in sliding contact with the guide rib 122. In one example, four guide ribs 122 are provided, with every two being provided on the same side wall of the guide window 121 , and the guide ribs 122 on the walls of the guide windows 121 on opposite sides are provided opposite to each other.

[0072] The elastic sliding assembly 3 is movably arranged in the guide structure 12 along the first direction, and the elastic sliding assembly 3 can abut against the ejection block 7 of the lock so as to move in the guide structure 12 under the push of the ejection block 7.

Among them, the slider 31 is movably arranged in the guide structure 12, and the slider 31 includes a main body 311, an abutting portion 312, a guide portion 313, a support portion 314 and a limiting portion 315. Specifically, the main body 311 has a shape that is compatible with the guide structure 12, and the main body 311 can be accommodated in the guide structure 12. When not in contact with the ejection block 7, part of the main body 311 of the slider 31 is distributed outside the guide window 121 of the guide structure 12. The abutment portion 312 is located at the bottom of the main body 311, with the bottom of the main body 311 facing the bottom of the latch. The abutment portion 312 is a portion of the main body 311 and includes an inclined end surface 3121 and a horizontal end surface 3122.

The inclined end surface 3121 is located at the front end of the main body 311, and the inclined end surface 3121 gradually increases in inclination from front to back. The front and rear ends of the main body 311 are defined by the insertion direction of the ejector block 7, that is, the front end of the abutment portion 312 first contacts the ejector block 7. The inclined end surface 3121 at the front end of the abutment portion 312 can abut the ejector block 7. Setting the front end of the abutment portion 312 as the inclined end surface 3121 allows the ejector block 7 to gradually lift the main body 311 after contact, while maintaining the lifted height at the horizontal end surface 3122. The support portion 314 is located at the top of the main body 311. One end of the spring 32 is sleeved and connected to the support portion 314, and the other end of the spring 32 is connected to the cover plate 2. In one example, the top and bottom of the main body 311 are opposite each other. The support portion 314 includes a support column, the axial direction of which is aligned with the first direction. One end of the spring 32 is sleeved and connected to the support column. There is only one support column.

[0073] The limiting portion 315 is located at both ends of the top of the main body 311 and is arranged to protrude from the main body 311 in the second direction. The limiting portion 315 can be formed to limit the cover plate 2 and the base 1 in the first direction, and can abut against the abutting end of the first power-carrying component 5. The second direction is perpendicular to the first direction. In one example, the limiting portion 315 includes a first limiting side plate 3151 and a second limiting side plate 3152, wherein the first limiting side plate 3151 is located at the front end of the main body 311 and the second limiting side plate 3152 is located at the rear end of the main body 311. The first limiting side plate 3151 and the second limiting side plate 3152 are respectively flat plate-shaped, and in the first direction, the cross-sectional area of the first limiting side plate 3151 is smaller than the cross-sectional area of the second limiting side plate 3152.

Furthermore, the first position-limiting side plate 3151 has a first side end surface and a second side end surface 3153, and the second position-limiting side plate 3152 has a third side end surface and a fourth side end surface 3154. The first and second side end surfaces 3153 oppose each other in a first direction, with the first side end surface constraining movement with the cover plate 2, and the second side end surface 3153 constraining movement with the base 1. The third and fourth side end surfaces 3154 oppose each other in the first direction, with the third side end surface contacting the abutting end of the first energizing component 5 to constrain movement, and the fourth side end surface 3154 constraining movement with the base 1.

There are four guide grooves, and every two guide grooves are arranged on the same side wall of the main body 311, and the guide grooves on the wall of the main body 311 on opposite sides are arranged relative to each other. The guide rib 122 is confined in the guide groove, guiding the main body 311 to move relative to the guide structure 12 in the first direction.

[0075] When the lock tongue of the lock is inserted into the lock, the ejection block 7 is pushed to abut against the inclined end surface 3121 of the abutment portion 312, and the guide rib 122 is confined in the guide groove. The ejection block 7 drives the slider 31 to move in the first direction away from the bottom of the lock. The spring 32 is compressed and has a restoring elastic force. The abutment end of the first power-carrying component 5 connected to the limiting portion 315 is driven, so that the abutment end of the second power-carrying component 6 is separated from the first power-carrying component 5 to form a circuit disconnection state.

The front end horizontal section is configured to be horizontal, and the front end horizontal section is located at the front end of the first spring 51, and the front end horizontal section abuts against the second limiting side plate 3152. The rear vertical section is located at the rear end of the first elastic piece 51 , and its vertical direction is in the first direction. The rear vertical section abuts against the first limiting body 132 in the second direction to limit the freedom of the first elastic piece 51 relative to the first limiting body 132 toward the front end.

[0077] Correspondingly, the second power-carrying component 6 includes: a second spring clip 61 and a second wiring harness 62, wherein the second spring clip 61 is installed in the second accommodating gap 135, and the abutting end of the second spring clip 61 is the abutting end of the second power-carrying component 6. The second wiring harness 62 is connected to the connecting end of the second spring clip 61.

Accordingly, the position-limiting boss 41 abuts the middle portion of the separating rib 131 and the top end surfaces of the first and second position-limiting bodies 132, 133. A limiting projection 42 protrudes from the limiting boss 41. After the plate 21 is attached to the second sidewall 16 of the base 1, the limiting projection 42 is located on the side of the limiting structure 13 in the third direction. The limiting projection 42 cooperates with the limiting structure 13 to limit the movement of the first and second energizing components 5 and 6 in the third direction, which is the lengthwise direction of the base 1. Corresponding to the rear vertical segments of the first and second spring clips 51 and 61, the limiting projection 42 and the first and second limiting bodies 132 and 133 clamp the rear vertical segments of the first and second spring clips 51 and 61 along the sidewalls in the second direction, thereby limiting the rearward freedom of the first and second spring clips 51 and 61 relative to the base 1.
