[0040] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0041] Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

[0042] Refer to Figure 1 and Figure 2 , an embodiment of the magnetic door lock 100 of the present invention includes a door lock 110 and a doorframe lock 120.

[0043] For the convenience of subsequent description, a first horizontal direction D1, a second horizontal direction D2 perpendicular to the first horizontal direction D1, and a longitudinal direction D3 perpendicular to the first horizontal direction D1 and the second horizontal direction D2 of the magnetic door lock 100 are defined. The first horizontal direction D1 is taken as the left-right direction as an example, Figure 1 the direction indicated by the arrow is to the left, and the reverse direction is to the right. The second horizontal direction D2 is taken as the front-back direction as an example, Figure 1 the direction indicated by the arrow is to the front, and the reverse direction is to the back. The longitudinal direction D3 is the up-down direction, Figure 1 the direction indicated by the arrow is up, and the reverse direction is down.

[0044] The door lock 110 is used to be installed on a door panel 11. The doorframe lock 120 is used to be installed on a doorframe 12. The doorframe 12 has a frame body 121 and a rubber strip 122 disposed on the frame body 121. The frame body 121 has a side wall 123 and an end wall 124 connected to the side wall 123 (as Figure 7As shown. The side vertical wall 123 and the end vertical wall 124 each extend along the longitudinal direction D3. An installation hole 125 is formed in the side vertical wall 123, and two screw holes 126 are respectively located on the upper and lower sides of the installation hole 125. The rubber strip 122 is disposed on the end vertical wall 124 to block the door panel 11.

[0045] Referring to Figure 1 , Figure 2 and Figure 3 , the door lock 110 includes a housing 21, a locking tongue 24, and a driving member 28. The housing 21 is installed on the door panel 11 and is formed with a guide groove 211 and an opening 212 communicating with the guide groove 211. The locking tongue 24 includes a locking sleeve 25 slidably engaged with the guide groove 211 and a magnet 27 disposed in the locking sleeve 25. The locking tongue 24 can be operated to slide between a locking position (as shown in Figure 2 ) and an unlocking position (as shown in Figure 6 ). In the locking position, a part of the locking sleeve 25 protrudes out of the opening 212. In the unlocking position, the locking sleeve 25 retracts into the guide groove 211. The driving member 28 is movably disposed in the guide groove 211 and can be operated to drive the locking tongue 24 to slide from the locking position to the unlocking position. Due to the configuration relationship among the housing 21, the locking tongue 24, and the driving member 28, the door lock 110 has fewer components, can improve the assembly convenience, and can make the overall structure of the door lock 110 simple and small in size to reduce the manufacturing cost.

[0046] The housing 21 includes a first housing 22 and a second housing 23 assembled to the first housing 22. The first housing 22 is a single member made of a metal material by an integral molding method. The first housing 22 has an end plate 221 and a half shell cover 222 integrally formed at one end of the end plate 221. The end plate 221 is in the shape of a long plate and its length direction extends along the longitudinal direction D3. The end plate 221 is formed with the opening 212 and two through holes 223 respectively located on the upper and lower sides of the opening 212. The shape of the opening 212 is taken as a square as an example but is not limited thereto. Each of the through holes 223 is used for a screw 13 to pass through, whereby the screw 13 can lock the end plate 221 to the door panel 11. The end plate 221 has two long side edges 224 spaced apart along the second horizontal direction D2. Each of the long side edges 224 is formed with two card slots 225 spaced apart vertically. The half shell cover 222 extends along the first horizontal direction D1 and surrounds the rear half of the opening 212. The half shell cover 222 has a plurality of spaced-apart stud bolts 226. The half shell cover 222 is formed with a pivot hole 227.

[0047] The second shell 23 is a single component made of metal in an integrally molded manner. The second shell 23 extends along the first horizontal direction D1. The second shell 23 is another half shell that matches the half shell 222. The second shell 23 covers the front end of the half shell 222 and surrounds the front half of the opening 212. The second shell 23 is formed with a plurality of positioning holes 231 for the studs 226 to pass through, and a pivot hole 232 corresponding to the position of the pivot hole 227. Each stud 226 partially protrudes from the second shell 23 to be screwed onto a nut (not shown), so that the second shell 23 and the half shell 222 can be locked together by the studs 226 and the nut. The end plate 221 of the first shell 22, the half shell 222, and the second shell 23 jointly define the guide groove 211. The guide groove 211 extends along the first horizontal direction D1 to guide the locking tongue 24 to slide along the first horizontal direction D1 between the locking position and the unlocking position.

[0048] Because the first housing 22 is a single component made of metal in an integrally molded manner, the first housing 22 has a strong structural strength. In addition, because the outer shell 21 is composed of two components, the first housing 22 and the second housing 23, the number of components of the outer shell 21 is reduced, which can improve assembly convenience.

[0049] See also Figure 2 、 Figure 3 、 Figure 4 and Figure 5, the latch sleeve 25 of the latch tongue 24 is a single member made by an integral molding method. In this embodiment, the latch sleeve 25 is made of nylon material that can achieve a silent effect. The latch sleeve 25 has a latch sleeve 250 passing through the opening 212, and a sliding rod 251 integrally formed at one end of the latch sleeve 250. The latch sleeve 250 has a cylinder 252 and a flange 253. The cylinder 252 is in the shape of a square cylinder and is sleeved on the magnet 27 and passes through the opening 212. The cylinder 252 has an end wall 254 and a surrounding wall 255 connected to the end wall 254. The surrounding wall 255 and the end wall 254 jointly define a receiving groove 256 for accommodating the magnet 27. The receiving groove 256 is, for example, in the shape of a circular groove but is not limited thereto. The magnet 27 is, for example, in the shape of a cylinder but is not limited thereto. The surrounding wall 255 has an inner peripheral surface 257 surrounding the receiving groove 256, and a plurality of pressing ribs 258 protruding from the inner peripheral surface 257 and arranged in a ring shape at intervals from each other. The pressing ribs 258 are used to tightly contact the magnet 27. The flange 253 protrudes from the outer peripheral surface of the surrounding wall 255 and is adjacent to one end of the surrounding wall 255 opposite to the end wall 254, and the flange 253 is located in the guide groove 211.

[0050] When assembling the magnet 27 to the latch sleeve 25, first align the magnet 27 with the receiving groove 256 of the latch sleeve 25. Subsequently, move the magnet 27 towards the end wall 254 and insert it into the receiving groove 256. When the magnet 27 abuts against the end wall 254, the assembly of the magnet 27 is completed. At this time, the pressing ribs 258 tightly contact the magnet 27, so that the magnet 27 can be fixed in the receiving groove 256. Thereby, it can be avoided that the latch sleeve 25 and the magnet 27 are loosened or detached when the magnet 27 is assembled in the receiving groove 256 due to manufacturing tolerances. In addition, due to the magnet 27 abutting against the end wall 254, the latch tongue 24 can maintain good magnetic force at the end wall 254.

[0051] In this embodiment, the receiving groove 256 extends along the first horizontal direction D1. Each of the pressing ribs 258 is in the shape of a long strip and its longitudinal direction extends along the first horizontal direction D1. Thereby, each of the pressing ribs 258 has a large range of tightly contacting the magnet 27 in the first horizontal direction D1, which can effectively improve the holding force of the pressing ribs 258 for holding the magnet 27, so that the magnet 27 can be firmly fixed in the receiving groove 256 without shaking in the receiving groove 256.

[0052] The sliding rod 251 is integrally connected to one end of the surrounding wall 255 opposite to the end wall 254 and the flange 253. The sliding rod 251 is used to be driven by the driving member 28. The sliding rod 251 is in the shape of a long rod and its longitudinal direction extends along the first horizontal direction D1. The sliding rod 251 has a first force-bearing surface 259 and a second force-bearing surface 260. The first force-bearing surface 259 and the second force-bearing surface 260 are spaced apart along the first horizontal direction D1 and arranged along the second horizontal direction D2. The second force-bearing surface 260 is located at an interval between the latch sleeve 250 and the first force-bearing surface 259. In this embodiment, a first slot 261 corresponding to the first force-bearing surface 259 and a second slot 262 corresponding to the second force-bearing surface 260 and communicating with the first slot 261 are recessed on one side of the sliding rod 251. By forming the first slot 261 and the second slot 262 on the sliding rod 251 to correspond to the first force-bearing surface 259 and the second force-bearing surface 260 respectively, the width of the sliding rod 251 in the second horizontal direction D2 can be reduced, thereby miniaturizing the volume of the sliding rod 251.

[0053] Refer to Figure 2 , Figure 3 , Figure 4 and Figure 6 , the driving member 28 has a pivot column 280 and a pushing arm 281. The pivot column 280 is pivotally connected to the pivot hole 227 of the first housing 22 and the pivot hole 232 of the second housing 23 rotatably. A through hole 282 is formed in the pivot column 280. The through hole 282 is used for a lock core (not shown in the figure) to pass through. The lock core is connected to a motor (not shown in the figure) for example, and the motor can drive the lock core to rotate to interlock the driving member 28 to rotate. The pushing arm 281 protrudes from the outer peripheral surface of the pivot column 280 and is used to push the sliding rod 251 so that the lock tongue 24 slides to the unlocking position. The pushing arm 281 has a first arm body 283 and a second arm body 284. The first arm body 283 is used to extend into the first slot 261 of the sliding rod 251. The first arm body 283 has a first pushing surface 285 for pushing the first force-bearing surface 259. The second arm body 284 is connected to one end of the first arm body 283 opposite to the first pushing surface 285 and is used to extend into the second slot 262 of the sliding rod 251. The second arm body 284 has a second pushing surface 286 angularly spaced from the first pushing surface 285, and the second pushing surface 286 is used to push the second force-bearing surface 260. The driving member 28 can be in an initial position (such as Figure 4 shown), and a blocking position (such as Figure 6It rotates between the positions shown. In the initial position, the pushing arm 281 does not block the sliding rod 251, enabling the lock tongue 24 to slide to the locking position. In the blocking position, the pushing arm 281 blocks the sliding rod 251, positioning the lock tongue 24 at the unlocking position.

[0054] One of the studs 226 is a first stop stud 226', and the other of the studs 226 is a second stop stud 226". The second stop stud 226" and the first stop stud 226' are spaced apart along the first horizontal direction D1 and are respectively located on the left and right sides of the pivot hole 227. The driving member 28 further has a first abutting block 287 and a second abutting block 288. The first abutting block 287 and the second abutting block 288 protrude from the outer peripheral surface of the pivot post 280 and are angularly spaced apart. The first abutting block 287 is connected to an end of the second arm body 284 opposite to the second pushing surface 286. The first abutting block 287 is used to abut against the first stop stud 226' to limit the driving member 28 in the initial position. The second abutting block 288 is used to abut against the second stop stud 226" to limit the driving member 28 in the blocking position.

[0055] Refer to Figure 3 、 Figure 4 and Figure 6 As shown in, the door lock 110 further includes a spring 29. The spring 29 is connected between the housing 21 and the driving member 28 to provide a reset elastic force for the driving member 28, so that the driving member 28 always remains in the initial position without blocking the lock tongue 24 from sliding towards the locking position. In this embodiment, the half-shell cover 222 of the first housing 22 further has a connecting post 228. The driving member 28 further has a connecting post 289 protruding from the outer peripheral surface of the pivot post 280. The spring 29 is a tension spring, and the two ends of the spring 29 are respectively connected to the connecting post 228 and the connecting post 289.

[0056] Refer to Figure 2 、 Figure 3 and Figure 4 As shown in, the door lock 110 further includes a buffer collar 30. The buffer collar 30 is sleeved on the cylinder body 252 of the lock catch slider 25 and is used to abut against the housing 21 and the flange 253. The buffer collar 30 is made of an elastic material such as rubber or silica gel. The buffer collar 30 is used to provide contact for the flange 253 of the lock catch slider 25 to prevent the flange 253 from directly hitting the end plate 221, so as to achieve the effects of buffering, decelerating and noise reduction.

[0057] The door lock 110 further includes a decorative plate 31. The decorative plate 31 is assembled to the end plate 221 of the housing 21 and covers the screw 13 to achieve an aesthetic effect. In this embodiment, the decorative plate 31 is formed with an opening 311 communicating with the opening 212. The decorative plate 31 includes a plurality of snap arms 312, and the snap arms 312 are respectively snapped into the card slots 225, so that the decorative plate 31 can be stably fixed to the end plate 221.

The lock plate 411 has a first long side 413 and a second long side 414 opposite to the first long side 413. The first long side 413 and the second long side 414 are spaced apart along the second horizontal direction D2. The first long side 413 and the second long side 414 are each formed with two card slots 415 spaced up and down. The lock plate 411 is formed with two through holes 416 spaced up and down. The through holes 416 respectively communicate with the screw holes 126. Each of the through holes 416 is used for a screw 14 to pass through, whereby the screw 14 can be screwed into the corresponding screw hole 126 through the through hole 416 to lock the lock plate 411 to the side wall 123.

[0059] The receiving box 412 protrudes from the back surface of the lock plate 411 and is spaced from the first long side 413 and the second long side 414. The receiving box 412 defines a center C, a first distance d1 is formed between the center C and the first long side 413, a second distance d2 is formed between the center C and the second long side 414, and the first distance d1 is greater than the second distance d2. The receiving box 412 and the lock plate 411 together define a receiving groove 417. The receiving groove 417 is used for the cylinder 252 of the lock catch sleeve 250 of the lock tongue 24 to be embedded. The receiving box 412 is formed with a back receiving groove 418 located at the back of the receiving groove 417 for accommodating the magnet 43. The magnet 43 is used to magnetically attract the magnet 27 of the lock tongue 24, so that the lock tongue 24 slides to the lock catch position where the lock catch sleeve 25 is embedded in the receiving groove 417.

[0060] Specifically, the receiving box 412 has an outer peripheral wall 419, a partition wall 420, an inner peripheral wall 421, and a plurality of studs 422.

The cover plate 45 is formed with a plurality of through holes 451 corresponding to the studs 422 respectively. Each screw 46 passes through the corresponding through hole 451 and is screwed to the corresponding stud 422. By shielding the magnet 43 with the cover plate 45, the magnet 43 can be prevented from being exposed and detached from the back receiving groove 418.

[0062] The decorative plate 47 is assembled to the locking plate 411 of the locking frame 41 and shields the screw 14, so as to achieve the effect of aesthetics. In this embodiment, the decorative plate 47 is formed with an opening 471 communicating with the receiving groove 417. The decorative plate 47 includes a plurality of snap spring arms 472, and the snap spring arms 472 are respectively snapped into the card slots 415, so that the decorative plate 47 can be stably fixed to the locking plate 411.

[0063] Refer to Figure 2 and Figure 4, when the door panel 11 is in a closed position relative to the door frame 12, the elastic force exerted by the spring 29 on the driving member 28 causes the first abutting block 287 to abut against the first stop post 226', so that the driving member 28 is always maintained in the initial position. At this time, the first arm body 283 of the pushing arm 281 partially extends into the first slot 261, and the first pushing surface 285 is adjacent to the first stress surface 259. The second arm body 284 of the pushing arm 281 is located below the sliding rod 251. By the magnet 43 of the door frame lock 120 magnetically attracting the magnet 27 of the lock tongue 24, the lock tongue 24 is held in the lock position where the cylinder 252 of the lock catch sleeve 25 is inserted into the receiving groove 417. Thereby, the door panel 11 can be locked to the door frame 12 by the magnetic lock 100 (as shown in Figure 1 ).

[0064] Refer to Figure 2 , Figure 4 and Figure 6 . When the door panel 11 is to be opened, the motor drives the lock core to rotate, so that the lock core drives the driving member 28 to rotate along a first rotation direction R1. Since the first pushing surface 285 is adjacent to the first stress surface 259, when the driving member 28 rotates, the first pushing surface 285 will first push the first stress surface 259, causing the lock tongue 24 to slide inward along the first horizontal direction D1 from the lock position. Then, the cylinder 252 of the lock catch sleeve 25 will gradually move away from the receiving groove 417 and contract into the guide groove 211. When the driving member 28 rotates to an appropriate angle, the second arm body 284 of the pushing arm 281 extends into the second slot 262, and the second pushing surface 286 of the second arm body 284 continues to push the second stress surface 260 to drive the lock tongue 24 to continue to slide inward along the first horizontal direction D1. During the above rotation process of the driving member 28, the spring 29 is pulled by the connecting column 289 to make it elongate and deform and accumulate the reset elastic force. When the second abutting block 288 abuts against the second stop post 226'', the driving member 28 is limited in the blocking position and cannot continue to rotate. At this time, the driving member 28 blocks the second stress surface 260 of the sliding rod 251 through the second pushing surface 286 to limit the lock tongue 24 in the unlocking position where the cylinder 252 of the lock catch sleeve 25 moves away from the receiving groove 417 and contracts into the guide groove 211. The user can open the door panel 11 from the closed position when the lock tongue 24 is in the unlocking position.

[0065] When the user rotates the door panel 11 back to the closed position, the motor stops operating by cutting off the power supply, causing the lock cylinder to be in a released state. At this time, the spring 29 pulls the connecting column 289 by the accumulated restoring elastic force, driving the driving member 28 to rotate in a second rotation direction R2 opposite to the first rotation direction R1. When the first abutting block 287 abuts against the first stop post 226', the driving member 28 is limited to the initial position and cannot continue to rotate. At the same time, the magnet 27 of the lock tongue 24 is attracted by the magnetic force generated by the magnet 43 of the doorframe lock 120, causing the lock tongue 24 to automatically slide outward along the first horizontal direction D1 from the unlocked position to the locked position where the cylinder 252 of the lock catch sliding sleeve 25 is inserted into the receiving groove 417.

[0066] By allowing the flange 253 and the cylinder 252 of the lock catch sliding sleeve 25 to contact the buffer collar 30 and the sound-absorbing block 44 respectively, the lock catch sliding sleeve 25 can be buffered, decelerated, and silenced. Thereby, it can avoid generating noise due to collision when the lock tongue 24 slides to the locked position, achieving a silent effect. The spring 29 provides a restoring elastic force for the driving member 28 to automatically reset the driving member 28 to the initial position, and the lock tongue 24 automatically slides to the locked position by the magnetic attraction of the magnet 43 to complete the locking, so that the above-mentioned locking action does not need to be achieved by the motor, thereby saving the power consumed by driving the motor to operate and achieving an energy-saving effect.

[0067] Refer to Figure 7 , Figure 10 , Figure 11 and Figure 12, by designing such that the first distance d1 between the center C of the receiving box 412 and the first long side 413 is greater than the second distance d2 between the center C and the second long side 414, the latch frame 41 has two different assembly methods. The first method is to assemble the latch frame 41 on the side wall 123 with the second long side 414 facing and approaching the rubber strip 122. The second method is to assemble the latch frame 41 on the side wall 123 with the first long side 413 facing and approaching the rubber strip 122. The assembler can select one of the above two methods to assemble the latch frame 41 according to the degree of tightness between the door panel 11 and the rubber strip 122 when the door panel 11 is in the closed position. For example, when the thickness of the rubber strip 122 is relatively thin, the assembler can select the first method to assemble the latch frame 41 on the side wall 123, so that the receiving box 412 and the receiving groove 417 are closer to the rubber strip 122. For example, when the thickness of the rubber strip 122 is relatively thick, the assembler can select the second method to assemble the latch frame 41 on the side wall 123, so that the receiving box 412 and the receiving groove 417 are farther away from the rubber strip 122. Thereby, when the door panel 11 is in the closed position, it can tightly contact the rubber strip 122, so as to reduce the situation that the door panel 11 shakes under the wind pressure.

[0068] To sum up, for the magnetic door lock 100 of this embodiment, due to the configuration relationship among the outer shell 21, the lock tongue 24 and the driving member 28, the components of the door lock 110 are few, the assembly convenience can be improved, and the overall structure of the door lock 110 is simple and the volume is small, so as to reduce the manufacturing cost. In addition, due to the design of the buffer collar 30 and the sound-absorbing block 44, it can avoid the noise generated by the collision when the lock tongue 24 slides to the locking position, so as to achieve the sound insulation effect. Furthermore, since the latch frame 41 has two different assembly methods, it provides the assembler with the ability to adjust the latch frame 41 according to the door frame 12, so that when the door panel 11 is in the closed position, it can tightly contact the rubber strip 122, thereby reducing the situation that the door panel 11 shakes under the wind pressure, and truly achieving the purpose claimed in the present invention.
