[0052] like Figures 1-11 As shown, this application provides a safety switch holder 1, including: a switch holder body 2 and a sealing block 5; the switch holder body 2 is connected to the first side of a locking body 20 through a connecting structure 3 provided thereon, and the outer side end of the switch holder body 2 is provided with a receiving groove 25; the locking body 20 is disposed in a seat belt buckle; the receiving groove 25 is used to receive a PCB assembly 4; the sealing block 5 has an installation form adapted to the receiving groove 25 and seals the PCB assembly 4 in the receiving groove 25.

[0053] Specifically, in this embodiment, the switch holder 1 includes a switch holder body 2 and a sealing block 5. The switch holder body 2 is connected to the first side of the locking body 20 via a connecting structure 3, and a receiving groove 25 is provided on the outer side of the switch holder body 2. The locking body 20 is located in the seatbelt buckle and unlocks in conjunction with the unlocking button 30. The receiving groove 25 is used to accommodate the PCB assembly 4. The sealing block 5 has an installation form adapted to the receiving groove 25 and seals the PCB assembly 4 within the receiving groove 25.

[0054] Furthermore, in this embodiment, the size of the switch body 2 is set according to the installation space between the housing 10 and the locking body 20. In one example, the switch body 2 includes an integrally formed connecting portion 21 and a support receiving portion 22, wherein the connecting portion 21 and the support receiving portion 22 are connected sequentially in a first direction along the insertion of the locking tongue. The connecting portion 21 is used to connect to the ejector block, and the support receiving portion 22 is mainly used to accommodate the PCB assembly 4. In one example, in a direction parallel to the first side of the locking body 20, the cross-section of the support receiving portion 22 is trapezoidal, and the support receiving portion 22 is mainly used to accommodate the PCB assembly 4. The cross-section of the connecting portion 21 is square. In a second direction perpendicular to the first side of the locking body 20, the connecting portion 21 and the support receiving portion 22 have a certain thickness, which is sufficient to accommodate the PCB assembly 4 without affecting the installation of the switch body 2.

[0055] In this embodiment, the connecting structure 3 includes a positioning post 31, a first latching angle 32, a second latching angle 33, and a third latching angle 34. The positioning post 31 is located on the inner side of the switch base body 2 and at the connecting portion 21. The positioning post 31 is inserted into the positioning hole 201 on the first side of the locking body 20 along a second direction perpendicular to the first side of the locking body 20. In one example, at least one positioning post 31 is provided, and correspondingly, at least one positioning hole 201 is provided on the first side of the locking body 20. In another example, preferably only one positioning post 31 is provided, and correspondingly, preferably only one positioning hole 201 is provided on the first side of the locking body 20.

[0056] The first latching angle 32 is located on the inner side of the switch body 2 and at the edge of the connecting part 21, specifically at the edge of the inner side of the connecting part 21. The inner side of the switch body 2 or the inner side of the connecting part 21 is the side closest to the first side of the locking body 20. The first latching angle 32 is fastened along the second direction to the edge of the hollow structure on the bottom side of the locking body 20. The first latching angle 32 is used to limit the degree of freedom of the switch body 2 relative to the first side of the locking body 20 in a third direction. This third direction is opposite to the second direction. In one example, there is one first latching angle 32. The positioning pin 31 and the first snap angle 32 are respectively provided on both sides of the sliding groove 23 (hereinafter). When the positioning pin 31 is inserted into the positioning hole 201 on the first side of the locking body 20, the positioning pin 31 can limit the degree of freedom of the switch body 2 relative to the first side of the locking body 20 in the first direction, and the first snap angle 32 limits the degree of freedom of the switch body 2 relative to the first side of the locking body 20 in the third direction. In one example, the first buckle 32 includes a first connecting arm 321 and a first limiting hook 322. The first connecting arm 321 and the first limiting hook 322 are integrally formed. The first connecting arm 321 is located at the edge of the inner side of the connecting part 21. The first connecting arm 321 extends along the second direction on the bottom side of the locking body 20. The first limiting hook 322 is connected to the end of the first connecting arm 321. The first limiting hook 322 engages with the edge of the hollow structure on the bottom side of the locking body 20, so as to limit the degree of freedom of the switch body 2 relative to the first side of the locking body 20 in the third direction, while connecting the switch body 2 to the first side of the locking body 20.

[0057] The second latching angle 33 is located on the inner side of the switch body 2 and at the edge of the support receiving portion 22, specifically at the edge of the inner side of the support receiving portion 22. The inner side of the switch body 2 or the inner side of the support receiving portion 22 is the side closest to the first side of the locking body 20. The second latching angle 33 is fastened to the rear edge of the first side of the locking body 20 along the second direction. The second latching angle 33 is used to limit the degree of freedom of the switch body 2 relative to the first side of the locking body 20 in the first direction and to limit the degree of freedom of the switch body 2 relative to the first side of the locking body 20 in the third direction. In one example, there is only one second latching angle 33. In one example, the second latch 33 includes a second connecting arm and a second limiting hook, which are integrally formed. The second connecting arm is located at the edge of the inner side of the support receiving portion 22, and the second limiting hook is connected to the end of the second connecting arm. The second connecting arm abuts against the edge of the inner side of the support receiving portion 22 to limit the degree of freedom of the switch body 2 relative to the first side of the locking body 20 in a first direction. The second limiting hook engages with the edge of the first side of the locking body 20 to connect the switch body 2 to the first side of the locking body 20 while limiting the degree of freedom of the switch body 2 relative to the first side of the locking body 20 in a third direction.

[0058] The third latching angle 34 is located on the inner side of the switch body 2 and at the edge of the support receiving portion 22, that is, at the edge of the inner side of the support receiving portion 22. The inner side of the switch body 2 or the inner side of the support receiving portion 22 is the side end close to the first side of the locking body 20. The third latching angle 34 is fastened to the upper edge of the first side of the locking body 20 along the second direction. In one example, there is one third latching angle 34. In one example, the third latching angle 34 includes a third connecting arm and a third limiting hook, which are integrally formed. The third connecting arm is located at the edge of the inner side of the support receiving portion 22 and is located on the side of the second connecting arm. The third limiting hook is connected to the end of the third connecting arm and engages with the edge of the first side of the locking body 20 to connect the switch body 2 to the first side of the locking body 20 while limiting the degree of freedom of the switch body 2 relative to the first side of the locking body 20 in the third direction.

[0059] In this embodiment, the connecting structure 3 further includes a connecting hole 35 and a connecting post. The connecting hole 35 is located on the inner side of the switch base body 2, specifically at the edge of the inner side of the support receiving portion 22. The holes of the connecting hole 35 are distributed along a second direction. The connecting post is located on the first side of the locking body 20 opposite to the connecting hole 35, and is also distributed along the second direction. The connecting hole 35 and the connecting post are engaged. The connecting hole 35 and the connecting post, in conjunction with the positioning post 31, the first latching angle 32, the second latching angle 33, and the third latching angle 34, connect the switch base body 2 to the first side of the locking body 20.

[0060] In this embodiment, the receiving groove 25 includes a first receiving groove 251 and a second receiving groove 252. The first receiving groove 251 has a shape and structure adapted to the PCB assembly 4, and the PCB assembly 4 is received in the first receiving groove 251. In one example, the first receiving groove 251 includes a horizontal slot and an L-shaped slot, which are connected. The horizontal slot is the state structure in which the switch body 2 is mounted on the locking body 20 when the seat belt buckle is placed horizontally. The L-shaped slot includes a first slot and a second slot that are perpendicular to each other, and there are two L-shaped slots, namely the first L-shaped slot and the second L-shaped slot. The first L-shaped slot is located outside the second L-shaped slot. The second receiving groove 252 is located above the first receiving groove 251 along the thickness direction of the switch body 2. The second receiving groove 252 has a shape and structure adapted to the sealing block 5, and the sealing block 5 is received in the second receiving groove 252. In one example, the second receiving groove 252 has an L-shaped structure, and the L-shaped second receiving groove 252 includes mutually perpendicular rectangular strip grooves and square grooves. Correspondingly, the sealing block 5 includes mutually perpendicular rectangular strip blocks and square blocks, with the rectangular strip blocks embedded in the rectangular strip grooves and the square blocks embedded in the square grooves. In one example, the sealing block 5 can be formed or replaced by encapsulation and potting. The sealing block 5 can play a role in waterproofing and dustproofing, so that the encapsulated PCB assembly 4 will not be affected by water and dust.

[0061] In one example, in order to securely connect the sealing block 5, a support connecting block and a locking hole are provided in the receiving groove 25. The support connecting block and the locking hole are arranged opposite to each other. When the sealing block 5 is fastened in the receiving groove 25, the support connecting block and the locking hole are engaged to provide a fixed support for the sealing block 5.

[0062] In one example, the sealing block 5 also includes a handle block connected to the outside of the rectangular strip block and the square block, so as to remove the sealing block 5 from the second receiving groove 252 by driving the handle block.

[0063] The PCB assembly 4 can be installed in the receiving groove 25. Specifically, in this embodiment, the PCB assembly 4 includes a substrate 40, a Hall sensor 41, a resistive element, and a wiring harness 42. The substrate 40 is installed in the first receiving groove 251, and the Hall sensor 41 and the resistive element are respectively disposed on the substrate 40. The Hall sensor 41 can be used to sense magnetic induction. One end of the wiring harness 42 is connected to the resistive element and the Hall sensor 41, and the other end of the wiring harness 42 is located outside the first receiving groove 251 via a sealing block 5.

[0064] Corresponding to the structure of the first receiving groove 251 described above, the substrate 40, the Hall sensor 41, and the resistive components are installed in the horizontal slots of the first receiving groove 251. Two wire harnesses 42 are provided, each wire harness 42 being installed in the first L-shaped slot and the second L-shaped slot respectively. After the PCB assembly 4 is installed, the sealing block 5 is embedded in the second receiving groove 252, thereby installing the PCB assembly 4 in the receiving groove 25.

[0065] In one example, the PCB assembly 4 includes a Hall sensor 41 and a wiring harness 42. One end of the wiring harness 42 is connected to the Hall sensor 41, and the other end of the wiring harness 42 is located outside the first receiving groove 251 via a sealing block 5. This structure of the PCB assembly 4 is simpler, saves space when installed in the receiving groove 25, and also reduces manufacturing costs and complexity.

[0066] Corresponding to the structure of the PCB assembly 4 described above, its installation in the receiving groove 25 is as follows: the receiving groove 25 includes a first receiving groove 251 and a second receiving groove 252. The first receiving groove 251 has a structural form adapted to the Hall sensor 41, and the Hall sensor 41 is housed within the first receiving groove 251. The second receiving groove 252 has a structural form adapted to the sealing block 5, and the sealing block 5 is housed within the second receiving groove 252. Of course, in one example, corresponding to the supporting connecting block, while connecting the supporting sealing block 5, the supporting connecting block can also limit the movement of the Hall sensor 41, that is, further limit the movement of the Hall sensor 41 within the first receiving groove 251.

[0067] In this embodiment, the switch holder body 2 further includes a wire harness 42 clamping buckle 24, which is used to clamp the wire harness 42 in the PCB assembly 4. Specifically, the wire harness 42 clamping buckle 24 is located at the end of the support receiving portion 22, and the wire harness 42 clamping buckle 24 can abut against the first side of the locking body 20 in a first direction. The wire harness 42 clamping buckle 24 is also used to limit the degree of freedom of the switch holder body 2 relative to the locking body 20 in a fourth direction. The fourth direction is opposite to the first direction.

[0068] In this embodiment, the switch base body 2 further includes a sliding groove 23, which is located on the inner side of the switch base body 2 and is positioned along the first direction of the latch insertion. The sliding groove 23 has a through opening and a limiting wall. The through opening is located at the front edge of the connecting portion 21. The ejector block slides into the sliding groove 23 through the through opening and is limited by the limiting wall. When the ejector block abuts against the limiting wall, it is in a second position. Further, in one example, one end of the ejector block at opposite ends slides into the sliding groove 23 through the through opening. A magnetic sensing element is disposed at one end of the ejector block at opposite ends, allowing the magnetic sensing element to sense the Hall sensor 41 of the PCB assembly 4 through the sliding groove 23.

[0069] This application provides a switch holder 1, including: a switch holder body 2 and a sealing block 5; the switch holder body 2 is connected to the first side of a locking body 20 through a connecting structure 3, and the outer side of the switch holder body 2 is provided with a receiving groove 25; the locking body 20 is disposed in a seat belt buckle; the receiving groove 25 is used to receive a PCB assembly 4; the sealing block 5 has an installation form adapted to the receiving groove 25 and seals the PCB assembly 4 in the receiving groove 25.

[0070] The switch holder 1 provided in this application is connected to the first side of the locking body 20 via its own connecting structure 3, thereby improving the stability of the connection between the switch holder 1 and the locking body 20. In addition, the outer side of the switch holder body 2 is provided with a receiving groove 25, which, while accommodating and installing the PCB assembly 4, can also further seal the PCB assembly 4 via a sealing block 5, thus preventing the PCB assembly 4 from being affected by water and dust. This also allows the switch holder 1 provided in this application to have a simple structure while still having the ability to assemble other structures.

[0071] This application also provides a seatbelt buckle, such as Figure 12 As shown, Figure 12 This is a schematic diagram of a seatbelt buckle provided in an embodiment of this application. The seatbelt buckle includes a switch base as described above. The specific structure of the switch base can be found in the description of the above embodiments, and will not be repeated here.
