[0028] The following describes a specific embodiment of the lock assembly according to the present invention in conjunction with the accompanying drawings. The following detailed description and accompanying drawings are used to illustrate the principles of the present invention. The present invention is not limited to the preferred embodiments described. The various embodiments described in the present invention may be used alone or in any combination. The scope of protection of the present invention is defined by the claims.

[0029] In addition, spatially relative terms (such as "upper," "lower," "left," and "right") are used to describe the relative positional relationship of an element shown in the drawings to another element. Therefore, the spatially relative terms can be applied to orientations different from those shown in the drawings when used. Obviously, although all of these spatially relative terms refer to the orientations shown in the drawings for ease of description, those skilled in the art will understand that orientations different from those shown in the drawings can be used.

[0030] Figures 1(a) and 1(b) respectively illustrate a Hall element in a lock assembly according to an embodiment of the present invention. The lock assembly, particularly the Hall element, according to an embodiment of the present invention will be described below with reference to Figures 1(a) and 1(b).

[0031] The present invention provides a lock assembly. The lock assembly includes a lock and a tongue (neither shown), and a Hall effect assembly 10 for detecting whether the tongue is inserted into the lock, as shown in Figures 1(a) and 1(b). The Hall effect assembly 10 can be fixed to an inner cavity of the lock, such as the inner space defined by the outer shell of the lock.

[0032] Continuing with Figures 1(a) and 1(b), in the lock assembly of the present invention, the Hall effect module 10 includes a chip 1, a magnet 2, and a housing 3. The chip 1 and magnet 2 are fixed to predetermined positions on the housing 3, and the chip 1 and magnet 2 overlap and are spaced apart along a predetermined direction. For the Hall effect module 10 in the orientation shown in Figure 1(a), the chip 1 and magnet 2 overlap, one above the other. That is, the projection of the chip 1 along the vertical direction at least partially overlaps with the magnet 2. When the lock tongue is inserted into the lock, the lock tongue is inserted into the space between the chip 1 and magnet 2 in the overlapping direction of the chip 1 and magnet 2, causing the magnetic field of the magnet 2 to change, resulting in a change in the current flowing through the chip 1 within this magnetic field. By obtaining different values ​​of the current flowing through the chip 1, it is determined whether the lock tongue is inserted into the lock, and thus whether the passenger is fastened. In one example, the chip and magnet overlap in a direction perpendicular to the insertion direction of the lock tongue into the lock, that is, the predetermined direction is perpendicular to the insertion direction of the lock tongue into the lock. It can be understood that setting the predetermined direction perpendicular to the insertion direction of the lock tongue into the lock buckle is conducive to sensitively sensing whether the lock tongue is inserted into the lock buckle.

[0033] Figure 2 shows the housing of the Hall assembly in the lock assembly according to an embodiment of the present invention. Figures 3(a) and 3(b) respectively show the first positioning portion of the Hall assembly in the lock assembly according to an embodiment of the present invention, wherein Figure 3(a) is a partial view of the Hall assembly, and Figure 3(b) is a cross-sectional view along line AA of Figure 3(a). Figures 4(a) and 4(b) respectively show the second positioning portion of the Hall assembly in the lock assembly according to an embodiment of the present invention, wherein Figure 4(a) is a partial view of the Hall assembly, and Figure 4(b) is a cross-sectional view along line BB of Figure 4(a). The chip, magnet and housing in the Hall assembly are described in further detail below with reference to Figures 2, 3(a), 3(b), 4(a) and 4(b).

[0034] As shown in FIG2 , the housing 3 includes a first positioning portion 31 and a second positioning portion 32. The first positioning portion 31 is used to position the chip 1 in a first position, and the second positioning portion 32 is used to position the magnet 2 in a second position. As described above, after the chip 1 is positioned in the first position of the housing 3 via the first positioning portion 31 and the magnet 2 is positioned in the second position of the housing 3 via the second positioning portion 32, the chip 1 and the magnet 2 overlap and are spaced apart in a predetermined direction.

[0035] 3(a) and 3(b), the first positioning portion 31 on the housing 3 includes a cover 313, a base 312, and a first latch 311 rotatably connected to the cover 313, and the cover 313 and the base 312 define a first accommodation space for accommodating the chip 1. It should be noted that, as shown in FIG2, the first accommodation space for accommodating the chip 1 is not a closed space. The first accommodation space has a front opening for inserting the chip 1 (the front opening in FIG2), and also has a side opening (the left opening in FIG2) for the output and input terminals of the chip 1 to communicate with an external controller.

[0036] As shown in FIG3(a), the first latch 311 has a wider dimension at the end pivotally connected to the cover 313. The wider end is wider than the cover 313 and wider than the rest of the first latch 311. It can be clearly observed from the figure that the left and right sides of the wider end of the first latch 311 extend beyond its adjacent components, which makes it easy to apply force to the wider end, thereby driving the first latch 311 to rotate. As shown in FIG3(b), if the first latch 311 rotates upward from the illustrated position and reaches a certain position, the right side opening of the first accommodating space will be opened. For the convenience of description, the position to which the first latch 311 rotates upward is defined as the first rotation position. That is, when the first latch 311 rotates to the first rotation position, the first accommodating space is opened, and the chip 1 can be taken out of or placed into the first accommodating space. Furthermore, as shown in FIG3(b), the first latching member 311 is in its second rotational position. At this point, the first latching member 311 applies a force to the first side surface of the chip 1 (the right side surface in FIG3(b)), positioning the chip 1 in the predetermined position. Specifically, the second side surface of the chip 1 (the left side surface in FIG3(b)), opposite the first side surface, abuts against the first stop 312A provided on the first positioning portion 31. In other words, the chip 1 is positioned in the left-right direction of FIG3(b) via the first latching member 311 and the first stop 312A. According to one embodiment of the present invention, a first step is provided on the base 312, and this first step serves as the first stop 312A. As shown in FIG3(b), the left side of the base 312 is raised upward relative to the rest of the base to form the first step, and the left side of the chip 1 abuts against the right side of the first step surface of the base 312. Of course, this is merely an example; other forms of first stoppers (e.g., a boss) may also be used in the Hall effect assembly of the latch assembly of the present invention. In addition, although in the above embodiment, the first latch is described as being rotatably connected to the cover, the present invention is not limited to this. The first latch can also be rotatably connected to the base. This arrangement can also achieve the positioning of the chip on the housing.

[0037] Furthermore, as shown in FIG3( b ), the cover 313 is provided with a first rib 3131, which is located between the cover 313 and the chip 1. For example, a plurality of spaced-apart first ribs 3131 are provided. The first ribs 3131 apply a force to the top surface of the chip 1 so that the bottom surface of the chip 1 abuts against the base 312. In other words, the chip 1 is positioned in the vertical direction of FIG3( b ) by the first ribs 3131 and the right portion of the base 312.

[0038] Furthermore, as shown in FIG3(a), the cover 313 and the base 312 are provided with a pair of side edges that oppose each other. These side edges are respectively arranged opposite the third and fourth side surfaces (i.e., the left and right sides) of the chip 1, so that the third and fourth side surfaces of the chip 1 are respectively abutted against the cover 313 and the base 312. In other words, the chip 1 is positioned in the front-to-back direction of FIG3(b) via the side edges on the cover 313 and the base 312.

[0039] As shown in Figures 4(a) and 4(b), the second positioning portion 32 includes a second latch 321 and a second stopper 322, which define a second storage space for accommodating the magnet 2. As shown in Figure 4(b), the magnet 2 is already located in the second storage space. When the magnet 2 needs to be removed, a force is applied to the hook portion of the second latch 321 (located at the right end in Figure 4(b)) to deform it, thereby opening the right side opening of the second storage space. The magnet 2 then leaves the second storage space through this right opening. When the magnet 2 needs to be placed in the second storage space, a force is similarly applied to the hook portion of the second latch 321 to deform it, opening the right side opening of the second storage space. Furthermore, the second latch 321 applies a force to the first side surface of the magnet 2 (the right side surface in Figure 4(b)), causing the second side surface of the magnet 2 (the left side surface in Figure 4(b)) opposite the first side surface to abut against the second stopper 321. According to one embodiment of the present invention, the second stopper 322 is configured as a second step portion. Of course, this is merely an example, and other forms of second stoppers (e.g., a boss) may also be used in the Hall assembly of the lock assembly of the present invention.

[0040] As shown in FIG4( b ), the left side of the second stopper 322 is raised downward relative to the rest of the second stopper 322 to form a second step, and the left side of the magnet 2 abuts the right side of the second step of the second stopper 322. Furthermore, the right side of the second stopper 322 abuts the top surface of the magnet 2. Accordingly, as shown in FIG4( b ), the second latch 321 is provided with a second rib 3211, which is disposed between the second latch 321 and the magnet 2. For example, a plurality of spaced-apart second ribs 3211 are provided. The second ribs 3211 apply a force to the bottom surface of the magnet 2, causing the top surface of the magnet 2 to abut against the second stopper 322. In other words, the magnet 2 is positioned vertically in FIG4( b ) by the second rib 3211 and the right side of the second stopper 322. Furthermore, the magnet 2 is positioned horizontally in FIG4( b ) by the hook portion of the second latch 321 and the left side of the second stopper 322.

[0041] Furthermore, as shown in Figure 4(a), the second accommodation space includes two sidewalls 323 and a pair of rib-shaped stoppers 3231 located on the sidewalls 323 to limit the position of the magnet 2. The pair of stoppers 3231 are positioned opposite two opposing side surfaces of the magnet 2, such that the two side surfaces of the magnet 2 rest against the pair of stoppers 3231. In other words, the magnet 2 is positioned in the front-to-back direction of Figure 3(b) via the pair of stoppers 3231.

[0042] Returning to Figures 1(a) and 1(b), a first groove and a second groove spaced a predetermined distance apart are provided on the side wall of the housing 3, and the input end 121 and the output end 122 of the chip 1 are positioned in the first groove and the second groove, respectively. In addition, a first predetermined path and a second predetermined path are provided on the housing 3, and the first cable 111 and the second cable 112 are electrically connected to the input end 121 and the output end 122 of the chip 1 via the first predetermined path and the second predetermined path, respectively. In one example, as shown in Figure 1(b), the first predetermined path and the second predetermined path are defined by a locking portion in the form of an open clamp 33 acting on the first cable 111 and the second cable 112. In addition, a plurality of protrusions 34 are provided on the housing 3, which protrude inward from the inner side surface of the housing to abut against the cables to prevent the cables from moving unexpectedly.

[0043] As mentioned above, although the exemplary embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above specific embodiments, and the scope of protection of the present invention should be defined by the claims and their equivalents.
