The electronic lock includes a housing with a hole, and an induction module installed in the cover. In the hole of the casing, the induction module has a cam receiving groove, and the edge forming the cam receiving groove has two sides, and the upper and lower sides of the two sides are adjacent to an abutment portion respectively, and the four abutment portions have two diameters. Relatively positive, the lower edge forming the cam receiving groove has a bottom in the middle of the two abutting portions. The cam receiving groove defines an X axis and a Y axis. The distance between the two sides in the X axis direction is a, the distance from the bottom to the edge of the hole of the housing in the Y-axis direction is b, and the distance between two radially adjacent positive abutments is c, and a = b> c; the cover plate is installed on the induction mold On the set, the cover plate has a cam which is received in a cam receiving groove of the induction module and is rotatable in the cam receiving groove. The cam has two ends and the cam defines a long axis. The distance between the two ends in the long axis direction is d, and a = b> d> c; when the cover plate is at the initial position, the convex The long axis of the cam is aligned with the X axis of the cam receiving groove, and the two ends of the cam are aligned with the two sides of the cam receiving groove, respectively; when the cover is rotated to the fully rotated position, The long axis of the cam is aligned with the X axis of the cam receiving groove, and both ends of the cam are aligned with both sides of the cam receiving groove, respectively.

Please refer to FIG. 1 to FIG. 16 for a preferred embodiment of a cover positioning structure for creating an electronic lock. An electronic lock 1 has a housing 2, and a fingerprint module 3 (also can be Various sensor modules, not limited to fingerprint modules), a cover plate 4 is installed above the fingerprint module 3.

As shown in FIGS. 1 to 4 and 7, the casing 2 has a hole 21, and the fingerprint module 3 is installed in the hole 21 of the casing 2. The fingerprint module 3 has a fingerprint sensor 31. The fingerprint module 3 has a cylindrical accommodating slot 32 and a cam accommodating slot 33 connected above the fingerprint sensor 31, and a convex point 34 below. The cam accommodating slot 33 is approximately a U-shaped groove. The edge forming the cam receiving groove 33 has two sides 30, and the upper and lower sides of the two sides 30 respectively adjoin an abutment portion 35, and the four abutment portions 35 are opposite to each other in a radial direction to form the cam receiving groove 33. The lower edge has a bottom 36 in the middle of the two abutting portions 35. The cam receiving groove 33 defines an X-axis and a Y-axis. The distance between the two sides 30 in the X-axis direction is a, and in the Y-axis direction. The distance from the bottom 36 to the edge of the hole 21 of the casing 2 is b, and the distance between the two radially abutting abutting portions 35 is c, and a = b> c.

As shown in FIG. 2 and FIG. 6, one side of the cover plate 4 axially extends a cylinder 40. The other end of the cylinder 40 is connected to a cam 41. One side of the cover plate 4 has a position relatively positive to the cam 41. The concave portion 42, the cam 41 is approximately elliptical and has two end portions 45. The cam 41 defines a long axis 43. The distance between the two end portions 45 in the direction of the long axis 43 is d.

As shown in FIG. 1 to FIG. 7, the cover plate 4 is mounted on the fingerprint module 3. The cylinder 40 of the cover plate 4 is received in the cylindrical accommodation groove 32 of the fingerprint module 3. The cam 41 is received in the cam receiving groove 33 of the fingerprint module 3, and the cam 41 can be rotated in the cam receiving groove 33, so that the cover plate 4 can completely cover the fingerprint module 3 in a timely manner, and a = b> d> c, as shown in FIG. 5 to FIG. 7, when the cover plate 4 is in an initial position that completely covers the fingerprint module 3, the long axis 43 of the cam 41 is aligned with the cam receiving groove. X axis of 33, and the two ends 45 of the cam 41 will align the two sides 30 of the cam receiving groove 33, respectively. The bumps 34 of the fingerprint module 3 and the recesses 42 of the cover plate 4 will mesh with each other. Because d> c, a predetermined external force must be applied to turn the cover 4 to the left or right; as shown in Figs. 6 to 10, when the user applies a predetermined external force to the cover 4 to When turning left, the cam 41 of the cover plate 4 will rotate clockwise. Because d> c, both ends 45 of the cam 41 slide over the two radially opposite positive abutting portions 35 of the cam receiving groove 33, respectively. The user will feel a greater resistance When the rotation angle of the cam 41 exceeds 45 degrees, the resistance gradually decreases; as shown in FIGS. 6 to 7 and 11 to 13, after the rotation angle of the cam 41 is about 90 degrees, both ends of the cam 41 One of 45 will face the bottom 36 of the cam receiving groove 33, and the cover plate 4 will try to slide downward (counterclockwise) because of its own weight, but because d> c, the cover plate 4 will be resisted Is located in a swivel position, the two ends 45 of the cam 41 are respectively adjacent to an edge of two radially opposite positive abutting portions 35 of the cam receiving groove 33, and the fingerprint of the fingerprint module 3 The sensor 31 is partially exposed for user operation. A small part of the fingerprint sensor 31 of the fingerprint module 3 is covered by the cover 4. When the user presses the fingerprint on the fingerprint sensor, the finger The cover plate 4 can be pushed upwards, and the two end portions 45 of the cam 41 can be respectively located at two radially opposite abutting portions 35 adjacent to the cam receiving groove 33 or two other adjacent portions 35 adjacent to the cam receiving groove 33. The relatively positive radial abutment portions 35 move slightly; as shown in FIGS. 6 to 7 and 14 to 16, if the fingerprint module 3 is desired The texture sensor 31 can be completely exposed for better operation by the user. Then, the cover plate 4 is rotated clockwise, and the cam 41 of the cover plate 4 is rotated clockwise. Because d> c, both ends of the cam 41 When the portion 45 slides through the other two radially-positive abutting portions 35 of the cam accommodating groove 33, the user will feel a large resistance. When the rotation angle of the cam 41 is further rotated by about 90 degrees, The long axis 43 of the cam 41 is aligned with the X axis of the cam receiving groove 33, and the two ends 45 of the cam 41 are respectively aligned with both sides 30 of the cam receiving groove 33. Because d> c, the The cam 41 will be located in this position without being affected by its own weight. At this time, the cover plate 4 is in a fully unscrewed position, and the fingerprint sensor 31 of the fingerprint module 3 is completely not covered. Because the cam 41 of the cover plate 4 and the cam receiving groove 33 of the fingerprint module 3 are symmetrically designed, when the cover plate 4 completely covers the fingerprint module 3, the user applies a predetermined external force. When the cover plate 4 is rotated to the right, the cam 41 of the cover plate 4 is rotated counterclockwise, and the subsequent operation methods and corresponding positions are the same as those described above, so no further description is needed here.
