Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
The following describes a door lock structure according to the present invention with reference to the accompanying drawings.
As shown in fig. 1, the door lock structure includes a lock mechanism 1 and a first magnet assembly 2. In an alternative embodiment, the locking mechanism 1 may be provided on the door of the cabinet, and the first magnet assembly 2 is correspondingly provided on the cabinet to cooperate with said locking mechanism 1. In particular, the locking mechanism 1 comprises a second magnet assembly 11 and a drive mechanism 12, wherein the second magnet assembly 11 cooperates with the first magnet assembly 2 to effect locking/unlocking of the door with respect to the cabinet. For example, in one example of a door lock structure according to the present invention, the first and second magnet assemblies 2 and 11 each include a single-sided, two-pole magnetizing magnet (e.g., as schematically illustrated by fig. 2B); the drive mechanism 12 comprises a drive button mechanism 13 and a swivel mechanism 14, and the locking mechanism comprises a base 20 for carrying the drive mechanism 12 comprising the swivel mechanism 14 and the drive button mechanism 13. Wherein the rotating mechanism 14 comprises a rotating shaft 15, a connecting rod 16 and a rotating disc 17 which are matched and associated with the driving button mechanism 13, wherein one end of the connecting rod 16 is connected to the rotating shaft 15, the other end of the connecting rod 16 is connected to the rotating disc 17, and the second magnet assembly 11 is correspondingly arranged on the rotating disc 17. The turn disc 17 is rotatably connected to the base 20 and the drive button mechanism 13 is arranged in a channel 21 of the base 20, whereby a support of the drive mechanism 12 is achieved and the locking mechanism 1 can be arranged on the door via the base 20 (a simple and quick mounting of the locking mechanism is achieved).
When the box door is buckled with the box body for locking, the N pole and the S pole of the single-sided two-pole magnetizing magnet of the second magnet assembly 11 are respectively opposite to and attracted to the S pole and the N pole of the first magnet assembly 2 in a complete face-to-face mode, namely, the N pole of the second magnet assembly 11 and the S pole of the first magnet assembly 2 are opposite to each other (completely overlapped) and the S pole of the second magnet assembly 11 and the N pole of the first magnet assembly 2 are opposite to each other (completely overlapped) and attracted to each other, so that enough locking magnetic attraction force is provided for locking the box door and the box body.
When the door and the cabinet are unlocked to open the door, the drive button mechanism 12 is pushed to move (inward) along the channel 21, and the drive button mechanism 12 converts the movement (linear sliding movement) into a rotational movement of the rotating mechanism 13. Specifically, the linear movement of the driving button mechanism 12 will drive the rotation shaft 15 to rotate, the kinetic energy is transmitted to the rotating disc 17 through the connecting rod 16 connected to the rotation shaft 15, the rotating disc 17 is driven to rotate for a certain angle, and the second magnet assembly 11 disposed on the rotating disc 17 (e.g. embedded in the rotating disc) is driven to rotate relative to the first magnet assembly 2, so that the second magnet assembly 11 and at least part of the first magnet assembly 2 form an N pole and an S pole of the second magnet assembly 11 respectively opposite to the N pole and the S pole of the first magnet assembly 2 (as shown in fig. 3), and the second magnet assembly 11 and the first magnet assembly 2 are converted from the attraction state to the at least partial desorption state, so that the locking magnetic attraction force is significantly reduced, and the door can be opened (unlocked) with a small (unlocking) opening force.
In the above-described example of the door lock structure, the structure of the rotating mechanism 13 enables the arm of force (radius) of the rotating disc to be significantly (e.g., in multiples) enlarged, resulting in a lever effect, which can more effectively reduce the door-to-door unlocking force.
In an alternative embodiment of this example of the door lock structure, the magnet assembly may use multiple sets of magnets in combination, for example, in a manner similar to stacking wood, and the magnitude of the locking magnetic attraction force and the unlocking force can be flexibly adjusted according to actual conditions. Additionally or alternatively, in an alternative embodiment, the magnet assembly may be symmetrically distributed with multiple sets of magnets such that only a small degree of rotation is required to achieve at least a partial opposition of like poles of the magnet assembly to achieve a significant reduction in unlocking force.
Additionally or alternatively, in an alternative embodiment to the example door lock structure described above, the base 20 may be mounted to the door by a fixed arm 22 at the side thereof. For example, it may be mounted to the door via screws by means of the fixing arm 22.
Additionally or alternatively, in an alternative embodiment of the above-described example of the door lock structure, the second magnet assembly 11 may be arranged on the rotary disc 17 by means of a magnet box 18, for example fixed to the rotary disc 17 by means of the magnet box 18 being embedded in the rotary disc 17.
Additionally or alternatively, in an alternative embodiment to the above-described example of the door lock structure, a return spring 23 may be provided between the drive button mechanism 13 and the end of the channel 21, such that after the door is unlocked, the drive button mechanism can be automatically returned under the action of the spring to effect automatic return of the second magnet assembly 11 to facilitate subsequent locking of the door to the cabinet.
Additionally or alternatively, in an alternative embodiment of the above-described example of the door lock structure, when the second magnet assembly 11 is rotated by the sliding movement of the actuating button mechanism 13, the second magnet assembly 11 may be formed to be opposed to the first magnet assembly 2 by substantially about one-half of the area with like poles, which may ensure a significant reduction in the locking magnetic attraction force and a small door opening unlocking force.
In an alternative embodiment of the above-mentioned door lock structure example, additional magnets 30 (as shown in fig. 4) may be disposed on the door and the cabinet respectively facing each other, and the magnets may be ordinary single-sided single-pole magnetizing magnets, and the magnetic poles of the magnets disposed on the door and the magnetic poles of the magnets disposed on the cabinet are opposite to each other. This may further provide a locking magnetic attraction force when the door is closed to better achieve a locking seal.
The example of the door lock structure described above can be applied to any device that has a door and box structure and needs to be locked/unlocked, for example, a vehicle-mounted armrest refrigerator such as a vehicle center console box with a refrigerator function. Due to the particularity of the vehicle-mounted refrigerator, the vehicle-mounted refrigerator can vibrate along with an automobile in the driving process, so that the situation that articles stored in the refrigerator knock the door when the vehicle is braked or collided emergently to accidentally fly out and injure people on the vehicle is prevented; therefore, the door of the vehicle-mounted refrigerator needs to have a large locking force (generally 100N or more), and when the refrigerator is used, the unlocking force for opening the door needs to be small (generally about 15N) in order to meet the requirement of human engineering. According to the door lock structure of the utility model, when the second magnet component and the first magnet component form opposite magnetic pole faces, the locking magnetic attraction force meeting the requirements is provided, so that the safety is ensured (preventing articles in the refrigerator from flying out due to bumping) and good sealing is provided (preventing the refrigerator door from loosening due to bumping) so as to ensure the refrigeration performance; and when the driving mechanism is used for rotating the second magnet assembly relative to the first magnet assembly so that the second magnet assembly and the first magnet assembly form at least partial opposite magnetic poles with the same polarity, the locking magnetic attraction force can be obviously reduced so as to meet the requirement that the door is opened (unlocked) with smaller (unlocking) opening force. Therefore, according to the utility model discloses a locking mechanical system can set up (integrate) to the on-vehicle refrigerator chamber door (for example, take the vehicle central handle case door closure of refrigerator function) in order to satisfy the operation requirement of on-vehicle refrigerator. Further, the door lock structure according to the present invention can be applied to any situation such as a charged state or a non-charged state of a refrigerator, compared with a design using an electromagnet (which can only operate in a charged state), and does not cause a problem that a standby current exceeds 100 microamperes.
However, it should be understood that the door lock structure according to the present invention may also be applied to other devices, such as a storage box or a center console box without a refrigerator function.
Furthermore, in an alternative embodiment, the locking mechanism according to the invention may be provided on the box, while the first magnet assembly is correspondingly provided on the door. The specific locking and unlocking principles are similar to those of the related embodiments, and are not described in detail herein.
In the description of the present invention, it is to be understood that the terms "upper", "inner", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplified description, but do not indicate or imply that the device or element referred to must have a specific orientation configuration and operation, and therefore, should not be construed as limiting the present invention.
Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. Thus, a definition of "a first" or "a second" feature may explicitly or implicitly include one or more of the features.
While embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that combinations, variations, modifications, substitutions and alterations of the above embodiments may be made by those of ordinary skill in the art without departing from the scope of the present invention.
