Description

Technical Field

[0001] This invention relates to the field of luggage, and more particularly to a magnetic lock and a suitcase equipped with the magnetic lock. Background Technology

[0002] As people's living standards continue to improve, long and short-distance travel is becoming increasingly frequent. To facilitate carrying luggage, people often use suitcases as an essential item. To simplify the operation of suitcases, they have evolved from traditional zipper suitcases to aluminum frame suitcases, allowing for easy opening and locking with just two or three latches. Compared to traditional zipper suitcases, which require pulling the zipper all the way around, this is much simpler and more convenient. Currently, aluminum frame suitcases use external latches for opening and closing. When the user presses or moves the unlocking lever, the external latches disengage, allowing the suitcase to open; when closing, the latches need to be manually fastened. However, external latches also have the following disadvantages: 1. They are complex to operate, requiring a learning curve for first-time users, and are more time-consuming to close; 2. Generally, external latches require one or two latches to be exposed, resulting in a relatively complex appearance. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, one objective of the present invention is to provide a magnetic lock and suitcase that can easily and quickly open and close an aluminum frame suitcase in one step through a built-in magnetic buckle, thereby improving the user experience, reducing the difficulty of user operation, saving user operation time, and ensuring a simple appearance of the suitcase.

[0005] To achieve the above objectives, the first aspect of the present invention provides a magnetic lock, comprising: a lock frame having a lock groove, the interior of which is hollow to form a cavity; an unlocking component mounted on the lock frame; a slider disposed within the cavity at a position corresponding to the lock groove, the unlocking component being connected to the slider via a connector; and a lock block having a latch that can extend into the lock groove and engage with the slider; wherein the unlocking component can drive the slider to slide within the cavity via the connector, and magnets are provided within the latch, lock block, and slider, the attraction between the latch and the magnet within the slider being greater than the attraction between the latch and the magnet within the lock block.

[0006] In this technical solution, by setting magnets in the latch, locking block and slider, the magnetic lock can be opened and closed easily and quickly by utilizing the attraction between opposite poles or the repulsion between like poles of the magnets, thereby improving the user experience, reducing the difficulty of user operation and saving user operation time.

[0007] In the above technical solution, preferably, the slider includes a lock frame and a locking block installed on the lock frame. The locking block has a snap-fit ​​groove, the lock tongue is provided with a snap-fit ​​strip, and a snap-fit ​​hook that cooperates with the snap-fit ​​strip is provided in the snap-fit ​​groove.

[0008] In this technical solution, when the magnetic lock is locked, the attraction between opposite magnetic poles of the slider and the bolt is utilized to allow the hook to automatically engage with the locking strip on the bolt, thus achieving automatic locking of the magnetic lock. When the magnetic lock is unlocked, the slider slides downwards, causing the like poles of the magnets between the slider and the bolt to repel each other, and the opposite magnetic poles of the magnets between the bolt and the lock block to attract each other, thereby automatically disengaging the hook from the locking strip. By using the above method, the structure is simple, the operation is convenient, and the locking and unlocking are more convenient, faster, and more reliable.

[0009] In any of the above technical solutions, preferably, the locking strips are arranged on both sides of the locking tongue, and two locking strips are arranged on each side, with the distance between one of the locking strips on the same side and the locking block being smaller than the distance between the other and the locking block.

[0010] In this technical solution, two locking strips are set on each side of the locking tongue to ensure more reliable magnetic lock engagement; and the locking strips on the same side are at different distances from the lock block, so that the hook can automatically disengage from the locking strip during the sliding process of the lock frame driving the lock block, further reducing resistance during unlocking.

[0011] In any of the above technical solutions, preferably, the lock block has a recessed cavity, the bottom wall of the recessed cavity is provided with a lock hook, the lock tongue is provided with a slide, and the lock hook extends into the slide and can hook onto the bottom wall of the slide.

[0012] In this technical solution, when the magnetic lock is unlocked or locked, the bolt can slide on the lock block through the slide rail; when unlocking, the lock hook can hook the bolt to fix the bolt on the lock block and prevent it from shaking.

[0013] In any of the above technical solutions, preferably, the lock frame and the connector are provided with a travel groove, and the lock frame and the connector are provided with a matching concave structure and a convex structure along the perimeter of the travel groove, and the lock frame is provided with a column, which is located in the travel groove.

[0014] In this technical solution, through the matching concave and convex structures, the lock frame can slide synchronously when the connector slides, and the columns on the lock frame limit the sliding of the lock frame and connector within a certain range, avoiding the problem of magnetic lock damage caused by excessive operation of the unlocking component.

[0015] In any of the above technical solutions, preferably, a return spring is also included, with both ends of the return spring fixed to the lock frame and the connector, respectively.

[0016] In this technical solution, the reset spring can automatically reset the slider after the magnetic lock is unlocked.

[0017] In any of the above technical solutions, preferably, the connecting member includes: a drive rod connected to the unlocking member; a connecting rod connected to the slider; wherein, the connecting rod is provided with a protrusion with an opening, and the drive rod is provided with a locking block, which is engaged in the opening.

[0018] In this technical solution, through the cooperating locking blocks and protrusions, when the user controls the unlocking component, the drive rod controls the slider to slide through the connecting rod, thereby realizing the unlocking and locking actions of the magnetic lock, which is simple and convenient to operate.

[0019] The second aspect of the present invention provides a suitcase, comprising: a suitcase body; a suitcase lid hinged to the suitcase body; and a magnetic lock as provided in any of the technical solutions of the first aspect of the present invention, wherein one of the suitcase lid and the suitcase body is provided with a lock block and the other is provided with a lock frame. The magnetic lock comprises: a lock frame having a lock groove thereon, and the interior of the lock frame being hollow to form a cavity; an unlocking member installed on the lock frame; a slider disposed in the cavity at a position corresponding to the lock groove, the unlocking member being connected to the slider via a connector; and a lock block having a lock tongue thereon, the lock tongue being able to extend into the lock groove and engage with the slider; wherein the unlocking member can drive the slider to slide in the cavity via the connector, and magnets are provided in the lock tongue, the lock block, and the slider, the attraction between the lock tongue and the magnet in the slider being greater than the attraction between the lock tongue and the magnet in the lock block.

[0020] In this technical solution, the magnetic lock of the first aspect of the present invention is installed on the suitcase. Opening requires only one operation, and the suitcase automatically pops open; closing requires only bringing the lid close to the suitcase body, thus improving user experience, reducing operational difficulty, saving user time, and ensuring a clean appearance. Furthermore, the suitcase also possesses any of the aforementioned technical effects of the magnetic lock, which will not be elaborated further here.

[0021] In any of the above technical solutions, preferably, the suitcase is a trolley case, which can be an aluminum frame case.

[0022] In this technical solution, aluminum frame trolley cases are mostly made of PC and aluminum-magnesium alloy, which are not easily deformed and are sturdy.

[0031] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0033] The following reference Figures 1 to 7 A magnetic lock and a suitcase are described according to some embodiments of the present invention.

[0034] like Figure 1 As shown, a magnetic lock according to an embodiment of the present invention includes: a lock frame 110 with a lock groove 111, the interior of the lock frame 110 being hollow to form a cavity; an unlocking member 120 mounted on the lock frame 110; a slider 130 disposed in the cavity at a position corresponding to the lock groove 111, the unlocking member 120 being connected to the slider 130 via a connector; and a lock block 150 with a lock tongue 151, the lock tongue 151 being able to extend into the lock groove 111 and engage with the slider 130; wherein, the unlocking member 120 can drive the slider 130 to slide within the cavity via the connector, and magnets (not shown) are provided in the lock tongue 151, the lock block 150, and the slider 130, the attraction between the lock tongue 151 and the magnet in the slider 130 being greater than the attraction between the lock tongue 151 and the magnet in the lock block 150.

[0035] The unlocking component 120 is a knob, which can be rotated clockwise or counterclockwise to unlock the magnetic lock.

[0036] In this embodiment, by setting magnets in the latch 151, the lock block 150 and the slider 130, the magnetic lock can be opened and closed easily and quickly by utilizing the attraction between opposite poles or the repulsion between like poles of the magnets, thereby improving the user experience, reducing the difficulty of user operation and saving user operation time.

[0037] The working principle of the aforementioned magnetic lock of this invention is as follows:

[0038] When the magnetic lock is in the locked state, the latch 151 on the lock block 150 extends into the lock frame 110 through the lock groove 111. The slider 130 inside the lock frame 110 can lock the latch 151. At this time, the N pole of the magnet inside the slider 130 and the S pole of the magnet inside the latch 151 are attracted to each other (and vice versa). The S pole of the magnet inside the slider 130 and the N pole of the magnet inside the latch 151 are attracted to each other, ensuring greater stability when the magnetic lock is in the locked state. When the magnetic lock is unlocked, the knob is rotated. The knob controls the slider 130 to slide through the connector. During the sliding process, the S pole (or N pole) of the magnet inside the slider 130 moves away from the latch 151. The N pole (or S pole) of the inner magnet and the S pole (or N pole) of the inner magnet near the latch 151 utilize the principle of like poles repelling each other. Furthermore, a magnet is also installed inside the lock block 150. The attraction between the lock block 150 and the magnet inside the latch 151 causes the latch 151 to automatically pop out of the lock frame 110, thus automatically unlocking the magnetic lock. When locking again, when the lock block 150 approaches the lock frame 110, the attraction between the slider 130 and the latch 151 is greater than the attraction between the latch 151 and the lock block 150. Therefore, the latch 151 can automatically slide into the lock frame 110 and engage with the slider 130, thus automatically locking the magnetic lock.

[0039] In the above embodiments, preferably, as follows: Figure 2 and Figure 5 As shown, the slider 130 includes a lock frame 131 and a locking block 132 mounted on the lock frame 131. The locking block 132 has a snap-fit ​​groove 133. The lock tongue 151 is provided with a snap-fit ​​strip 152 and a snap-fit ​​hook 134 that cooperates with the snap-fit ​​strip 152 is provided in the snap-fit ​​groove 133.

[0040] In this embodiment, when the magnetic lock is locked, the attraction between opposite magnetic poles of the slider 130 and the latch 151 is utilized to allow the hook 134 to automatically engage with the locking strip 152 on the latch 151, thus achieving automatic locking of the magnetic lock. When the magnetic lock is unlocked, the slider 130 slides downwards, causing the like magnetic poles of the slider 130 and the latch 151 to repel each other, and the attraction between opposite magnetic poles of the latch 151 and the lock block 150 is utilized to allow the hook 134 to automatically disengage from the locking strip 152. The above method of operation results in a simple structure, convenient operation, and more convenient and faster unlocking and locking, with high reliability.

[0041] Alternatively, to reduce the number of parts in the magnetic lock, the magnet can be set as the locking block 132, and a hook 134 can be provided inside the magnet.

[0042] Specifically, the locking strip 152 on the locking tongue 151 and the locking hook 134 on the locking block 132 are provided with, but are not limited to, the following technical solutions:

[0045] Among them, the height of one of the locking bars 152 on the same side of the locking tongue 151 is higher than the height of the other locking bar 152 on the locking tongue 151, and the distance between the locking bar 152 at the upper end of the locking tongue 151 and the locking block 150 is less than the distance between the locking bar 152 at the lower end of the locking tongue 151 and the locking block 150.

[0046] In this embodiment, two locking strips 152 are provided on each side of the locking tongue 151 to ensure more reliable locking of the magnetic lock; and the locking strips 152 on the same side are at different distances from the locking block 150. During the sliding of the locking block 150 by the locking frame 131, the hook 134 can also automatically disengage from the locking strips 152, further reducing the resistance during unlocking.
