[0061] 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.

[0062] Based on this, the present application provides a wiring harness switch.

[0063] Installed in the seat belt buckle, the wiring harness switch includes: a base, a cover plate, a slider, a limit connection structure, a first power-on component, and a second power-on component. The base is provided with a limit clamping structure, a guide structure, a limit accommodating structure, and an abutment space. The limit clamping structure is provided on the first side wall 16 of the base, and the base is connected to the lock body of the buckle via the limit clamping structure. The guide structure is provided on the inner side of the side wall of the base facing the bottom of the buckle. The limit accommodating structure is provided inside the base. The abutment space is provided at the front end of the base, the abutment space is connected to the guide structure, and the ejection block of the buckle slides into the abutment space. The limit connection structure is provided between the cover plate and the second side wall of the base, and the cover plate is connected to the base via the limit connection structure, and the limit accommodating structure cover is installed inside the base. The slider is provided in the guide structure for movement along a first direction, and the slider can abut against the ejection block that slides into the abutment space, so as to move in the guide structure under the push of the ejection block. The first power-on component and the second power-on component are installed in the limiting accommodating structure, and the abutting end of the first power-on component is connected to the slider. The abutting end of the second power-on component can be attached to or separated from the first power-on component. When the lock tongue of the lock pushes the ejection block to not be inserted into the abutting space, the slider is not driven, the abutting end of the first power-on component abuts the slider, and the abutting end of the second power-on component abuts the first power-on component to form a circuit path state. When the lock tongue of the lock pushes the ejection block to be inserted into the abutting space, the slider is driven to move in the direction away from the bottom of the lock, and the slider is compressed with the reset elastic force provided by the first power-on component. The abutting end of the first power-on component connected to the slider is driven, so that the abutting end of the second power-on component is separated from the first power-on component to form a circuit disconnection state.

Secondly, the abutting end of the first power-on component is connected to the slider, and the abutting space is located inside the base and below the guide structure. When the lock tongue of the lock buckle pushes the ejection block to insert into the abutting space, the abutting end of the first power-on component connected to the slider is driven, so that the abutting end of the second power-on component is separated from the first power-on component to form a circuit-disconnected state, thereby achieving the stability of the physical connection and accurately turning the power on and off according to the movement of the lock tongue and the ejection block, further improving the accuracy of the induction warning.

[0066] like Figures 1 to 9 As shown, the present application provides a wiring harness switch installed in a seat belt buckle. The wiring harness switch includes: a base 1, a cover plate 2, a slider 3, a position-limiting connection structure 4, a first power supply component 5, and a second power supply component 6. The base 1 is provided with a position-limiting clamping structure 11, a guide structure 12, a position-limiting accommodating structure 13, and an abutment space 14. The position-limiting clamping structure 11 is provided on a first side wall 16 of the base 1, and the base 1 is connected to the lock body of the buckle via the position-limiting clamping structure 11. The guide structure 12 is provided on the inner side of the side wall of the base 1 facing the bottom of the buckle. The position-limiting accommodating structure 13 is provided within the base 1. The abutment space 14 is provided at the front end of the base 1 and is connected to the guide structure 12. The ejection block of the buckle slides into the abutment space 14. The position-limiting connection structure 4 is provided between the cover plate 2 and a second side wall 17 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 installed within the base 1. The slider 3 is movably disposed in the guide structure 12 along a first direction. It can abut against an ejection block slidably connected to the abutment space 14, allowing it to move within the guide structure 12 under the push of the ejection block. The first and second energizing components 5, 6 are mounted in the position-limiting accommodating structure 13, with the abutting end of the first energizing component 5 connected to the slider 3. The abutting end of the second energizing component 6 can engage or disengage relative to the first energizing component 5. When the latch's locking tongue pushes the ejection block, which is not inserted into the abutment space 14, the slider 3 is not driven, the abutting end of the first energizing component 5 abuts against the slider 3, and the abutting end of the second energizing component 6 abuts against the first energizing component 5, forming a circuit path. When the lock tongue of the lock pushes the ejection block to insert into the abutment space 14, the slider 3 is driven to move away from the bottom of the lock, and the slider 3 is compressed with the reset elastic force provided by the first power-carrying component 5. The abutment end of the first power-carrying component 5 connected to the slider 3 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.

[0067] Specifically, in this embodiment, the base 1 includes a base body, a position-limiting snap-fitting structure 11, a guide structure 12, a position-limiting accommodating structure 13, and an abutment space 14. The base body is an irregular cubic structure having a first sidewall 16, a second sidewall 17, a third sidewall, and a fourth sidewall 18. The first sidewall 16 and the second sidewall 17 are disposed opposite each other, and the third sidewall 18 and the fourth sidewall 18 are disposed opposite each other. The first sidewall 16, the third sidewall, and the fourth sidewall 18 together form the main portion of the base body, and the cover 2 is mounted on the second sidewall 17. The position-limiting snap-fitting structure 11 is disposed on the first sidewall 16 of the base 1, and the base 1 is connected to the lock body of the lock catch via the position-limiting snap-fitting structure 11. Specifically, in one example, the position-limiting snap-fitting structure 11 includes a first position-limiting hook 112, a second position-limiting hook 113, and a third position-limiting hook 114. A first limiting hook 112 protrudes from the middle of the first side wall 16 of the base 1. The first limiting hook 112 is mounted on the wall of the lock body of the lock catch. The hook of the first limiting hook 112 faces the rear end of the base 1 to limit the base 1's freedom of movement relative to the rear end of the lock body. A second limiting hook 113 protrudes from the first side wall 16 of the base 1. The limiting hook is mounted on the top of the lock body of the lock catch. The hook of the second limiting hook 113 faces the fourth side wall 18 of the base 1 to limit the base 1's freedom of movement relative to the side wall of the lock body. A third limiting hook 114 protrudes from the second side wall 17 of the base 1. The third limiting hook 114 is mounted on the bottom of the lock body of the lock catch. The hook of the third limiting hook 114 faces the third side wall of the base 1 to limit the base 1's freedom of movement relative to the side wall of the lock body.

[0068] The interior of the base 1 is provided with an open groove relative to the second side wall 17 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 and inclined strip 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 and long strip. The thick and 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 and long strip end and the thin and 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 18, and correspondingly, the second direction refers to the direction relative to the second side wall 17 and the first side wall 16. 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.

[0069] The guide structure 12 is arranged on the inner side of the side wall of the base 1 facing the bottom of the lock buckle, that is, the guide structure 12 is arranged inside the base 1. Specifically, the guide structure 12 includes a guide cavity 121, a guide rib 122 and a guide groove (not shown). Among them, the guide cavity 121 is formed on the side of the base 1 facing the bottom of the lock buckle, and is located at the front end of the base 1. The main body 31 of the slider 3 is accommodated in the guide cavity 121. The abutment space 14 is located below the guide cavity 121. The abutment space 14 is connected to the guide cavity 121. The guide rib 122 is protruding along the second direction and is arranged in the middle of the guide cavity 121, and specifically protrudes on the cavity wall of the guide cavity 121 near the rear end of the base 1. The guidance of the guide rib 122 is along the first direction, and the guide rib 122 and the wall of the guide cavity 121 form an accommodating gap in the first direction. The wall of the guide cavity 121 near the rear end of the base 1 has an inclined surface 123, which facilitates the discharge of dust and other debris. A guide rib 122 is positioned opposite the first guide portion 33, and the first guide portion 33 and the guide rib 122 are in sliding engagement. A guide groove is provided along the first direction in the wall of the guide cavity 121 and is provided with the second guide portion 34 of the slider 3, and the second guide portion 34 and the guide groove are in sliding engagement.

[0070] The slider 3 is movably arranged in the guide structure 12 along the first direction. The slider 3 can abut against the ejection block of the lock so as to move in the guide structure 12 under the push of the ejection block. Specifically, in this embodiment, the slider 3 includes a main body 31, an abutting portion 32, a first guide portion 33, a second guide portion 34 and a limiting portion 35. Specifically, the main body 31 has a shape that is compatible with the guide structure 12, and the main body 31 can be accommodated in the guide structure 12. The abutting portion 32 is located at the bottom of the main body 31, and the bottom of the main body 31 faces the bottom of the lock. The abutting portion 32 is a part of the main body 31. The abutting portion 32 includes an inclined end surface 321 and a horizontal end surface 322, wherein the inclined end surface 321 and the horizontal end surface 322 are arranged in a continuous manner, and the inclined end surface 321 is located at the front end of the main body 31. The inclination of the inclined end surface 321 from the front to the rear direction gradually rises. The front and rear ends of the main body 31 are defined by the direction of insertion of the ejector block. This means that the front end of the abutment portion 32 first contacts the ejector block. The front end of the abutment portion 32 has an inclined end surface 321 that abuts the ejector block. This inclined end surface 321 allows the ejector block to gradually lift the main body 31 after contact, maintaining the elevated height at the horizontal end surface 322.

[0071] The limiting portion 35 is located at both ends of the top of the main body 31 and is arranged to protrude from the main body 31 in the second direction. The limiting portion 35 can form a limit in the first direction relative to the base 1, and can abut against the abutting end of the first power-carrying component 5.

Furthermore, the limiting side plate 351 has a first side end face and a second side end face 352. The first side end face and the second side end face 352 are opposite to each other in the first direction, the first side end face contacts the abutting end of the first power-carrying component 5 to form a limit, and the second side end face 352 forms a motion limit with the base 1.

[0072] The first guide portion 33 is disposed at the rear end of the main body 31 along the first direction. In one example, the first guide portion 33 corresponds to the guide rib 122 of the guide structure 12, and includes a guide groove, the groove of which is distributed along the first direction. The guide rib 122 is defined in the guide groove, guiding the main body 31 to move relative to the guide structure 12 in the first direction. The second guide portion 34 is disposed on both sides of the main body 31 along the first direction. When the main body 31 is accommodated in the guide structure 12, the second guide portion 34 cooperates with the guide groove of the guide structure 12, and guides the main body 31 to move relative to the base 1 in the first direction through the second guide portion 34. Specifically, in one example, the second guide portion 34 includes guide ribs, which are disposed on opposite sides of the main body 31 in the second direction. Four guide ribs are provided, with each two guide ribs being disposed on the same side wall of the main body 31, and the guide ribs on the walls of the main body 31 on opposite sides are disposed oppositely, and the guiding directions of the guide ribs are distributed along the first direction.

[0073] When the lock tongue of the lock pushes the ejection block to insert into the abutment space 14, the ejection block is pushed to abut against the inclined end surface 321 of the abutment portion 32, the guide rib 122 is defined in the guide groove (first guide portion 33), and the guide rib (second guide portion 34) is defined in the guide groove (not shown). The ejection block drives the slider 3 to move in the first direction away from the bottom of the base 1, and the abutment end of the first power-carrying component 5 connected to the limiting portion 35 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-disconnected state.

[0074] In this embodiment, the first power-on component 5 and the second power-on component 6 are installed in the limiting accommodating structure 13. The first power-on component 5 includes: a first spring 51 and a first wiring harness 52, wherein the first spring 51 is installed in the first accommodating gap 134, and the abutting end of the first spring 51 is the abutting end of the first power-on component 5. The first wiring harness 52 is connected to the connecting end of the first spring 51.

[0077] The cover plate 2 is connected to the base 1 via a position-limiting connection structure 4. The position-limiting connection structure 4 includes a position-limiting protrusion 41, a receiving groove 42, a special-shaped cylindrical hole 43 (or a circular hole), and a special-shaped cylinder 44 (or a cylinder). The position-limiting protrusion 41 protrudes from the plate 21. After the plate 21 covers the second sidewall 17 of the base 1, the position-limiting protrusion 41 is located on the side of the position-limiting receiving structure 13 in the third direction. The position-limiting protrusion 41 cooperates with the position-limiting receiving structure 13 to limit the movement of the first and second power-carrying components 5 and 6 in the third direction. The third direction is the longitudinal direction of the base 1. Corresponding to the rear vertical segments of the first and second spring clips 51 and 61, the position-limiting protrusion 41 and the first and second position-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. A recessed accommodating groove 42 is formed in the plate body 21, with its opening facing the first and second energizing components 5 and 6. As previously mentioned, the bottom of the recess 42 abuts the center of the separating rib 131 and the top end surfaces of the first and second limiters 132 and 133, restricting movement of the first and second energizing components 5 and 6 relative to the position-limiting accommodating structure 13 in the second direction.

The position-limiting connection structure is provided between the cover plate and the second sidewall of the base. The cover plate is connected to the base via the position-limiting connection structure and covers the position-limiting accommodating structure within the base. The slider is movable in a first direction within the guide structure.

When the lock tongue of the lock pushes the ejection block to be inserted into the abutting space, the slider is driven to move in the direction away from the bottom of the lock, and the slider is compressed with the reset elastic force provided by the first power-on component. The abutting end of the first power-on component connected to the slider is driven, so that the abutting end of the second power-on component is separated from the first power-on component to form a circuit disconnection state.

Secondly, the abutting end of the first power-on component is connected to the slider, and the abutting space is located inside the base and below the guide structure. When the lock tongue of the lock buckle pushes the ejection block to insert into the abutting space, the abutting end of the first power-on component connected to the slider is driven, so that the abutting end of the second power-on component is separated from the first power-on component to form a circuit-disconnected state, thereby achieving the stability of the physical connection and accurately turning the power on and off according to the movement of the lock tongue and the ejection block, further improving the accuracy of the induction warning.
