Description

Technical Field

[0001] The utility model relates to the field of automobile interior decoration, in particular to a socket component. Background Art

[0002] German patent publication number DE102012010011A1 discloses a "closing and unlocking device for receiving movable parts", which uses the magnetic repulsion of like magnetic poles to move the locking part in the recessed groove to unlock and reset it through the vertical force of the coil spring. However, the disadvantage of this patent is that the vertical arrangement space occupied by the recessed groove is large, and the locking part will be unstable to a certain extent due to its fixed guide structure during the magnetic repulsion process, which in turn affects the comfort of the unlocking process.

[0003] Chinese patent publication number CN104442597B discloses a "retaining device for fixing electrical appliances in motor vehicles", which is set to attract opposite magnetic poles of two interactive elements, so that the bracket element swings and presses down the latch element to unlock. Similarly, this invention has many parts arranged in the vertical space, and the structure and assembly difficulty are relatively complex. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the purpose of the utility model is to provide a socket assembly, which on the one hand solves the problem of local depression in the locked state due to lack of support when the door panel is long, and on the other hand improves the ease of use during the unlocking operation.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A socket assembly includes a door panel movably arranged on the socket, a magnetic latch is arranged on the back side of the door panel and can be unlocked by sliding to switch the door panel between an open state and a locked state, and at least one lock tongue extends from the edge of the magnetic latch and abuts against the outer frame of the socket to put the door panel in a locked state.

[0007] Furthermore, the at least one locking tongue comprises at least one first locking tongue whose extending direction is different from the sliding direction of the magnetic latch.

[0008] Furthermore, at least one opening is formed on the outer frame, and after the first lock tongue slides along with the magnetic lock latch, the projection of the first lock tongue is located in the opening and is out of contact with the outer frame to achieve unlocking.

[0009] Furthermore, the at least one locking tongue further includes at least one second locking tongue whose extending direction is the same as the sliding direction of the magnetic lock latch.

[0010] Furthermore, the second lock tongue slides with the magnetic lock latch and retracts toward the door panel, breaking away from the outer frame to achieve unlocking.

[0011] Furthermore, a bracket is provided on the back side of the door panel, and the magnetic latch is limited and slidable through the bracket.

[0012] Furthermore, a latch torsion spring is provided on the back side of the door panel, and the latch torsion spring provides a reset force to the magnetic latch so that the magnetic latch tends to remain in the locked position.

[0013] Furthermore, the extending direction of the first lock tongue is perpendicular to the sliding direction of the magnetic lock latch.

[0014] Furthermore, a latch magnet is provided on the magnetic latch, and the unlocking sliding of the magnetic latch is achieved by the magnetic field alignment force of the mutual attraction between the external magnet and the latch magnet.

[0015] Furthermore, it also includes a latch that is inserted into the socket after unlocking the door panel, and the external magnet is a latch unlocking magnet arranged on the latch.

[0016] Furthermore, a door panel magnet is also provided on the door panel, and a latch positioning magnet which is attracted correspondingly to the door panel magnet is also provided on the latch. The door panel magnet and the latch positioning magnet constitute a reference for unlocking the latch.

[0017] Furthermore, the distance between the latch magnet and the door panel magnet is slightly greater than the distance between the latch unlocking magnet and the latch positioning magnet.

[0018] Furthermore, the magnetic poles of the latch magnet and the door panel magnet facing the latch pin are in opposite directions.

[0019] In summary, the beneficial effects of the utility model are: the corresponding lock tongue and opening can be set according to the actual opening size, the locking is firm, and the double magnet structure also reduces the difficulty of the unlocking operation and prevents unlocking failure.

[0026] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "left", "right", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings. Longitudinal (X direction)", "lateral (Y direction)" and "vertical (Z direction)" are terms in the space coordinate system in the automotive field, and are professional terms well known to those skilled in the art. The above description is simplified for the convenience of describing the present invention, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0027] The following will describe exemplary embodiments of the present application with reference to the accompanying drawings. However, it should be understood that the present application can be presented in a variety of different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all drawings, the same reference numerals represent the same or functionally identical elements.

[0028] Figure 1 The overall structure of the magnetic lock mechanism is shown. After the frame 10 and the housing 20 are assembled, they are set on the automobile interior as an assembly mechanism, so that the external functional parts (such as hangers, mobile phone holders, etc.) can be detachably fixed in the automobile interior by passing through the socket 11 with the latch structure (not shown in the figure). The socket 11 is provided with a door panel 30, and the rear side of the door panel 30 is provided with a magnetic latch 50 that implements the unlocking function through the latch magnet 56 and the door panel magnet 33. A base 40 for carrying the above-mentioned latch is also provided in the housing 20, and the tongue-and-groove structure that cooperates with the door panel 30 and the magnetic latch 50 realizes the locking function of the door panel 30 together.

[0029] Figure 2 and Figure 3The structure in the locked state is shown, with a rotating shaft 31 passing through the top of the door panel 30, and both ends of the rotating shaft 31 are connected to the frame 10 so that the door panel 30 is hinged on the frame 10. A door panel torsion spring 32 is also arranged on the rotating shaft 31 so that the door panel 30 always tends to flip downward to keep the socket 11 closed. There is a bracket 53 on the back side of the door panel 30, and the magnetic latch 50 is slidably arranged on the door panel 30 through the bracket 53. Specifically, the bracket 53 has a pair of ridges along the Y direction and parallel to each other. The magnetic latch 50 is arranged between the ridges and the Z-direction and X-direction degrees of freedom are limited by the ridges, so that the magnetic latch 50 slides in the slide rail structure formed by the ridges. The bottom of the magnetic latch 50 has at least one first lock tongue 52 extending in the Z direction, and the back side of the first lock tongue 52 abuts against the front side of the bottom frame 41 of the base 40 to prevent the door panel 30 from flipping backward and opening, so that the door panel 30 is in a locked state. Combined with Figure 4 and Figure 5 At least one opening 42 is provided on the bottom frame 41, and the number of the openings 42 is the same as that of the first lock tongue 52. When the first lock tongue 52 slides and unlocks with the magnetic latch 50, the first lock tongue 52 coincides with the projection of the opening 42 in the X direction, so that when the door panel 30 is flipped open, the first lock tongue 52 can move through the opening 42. Furthermore, at least one second lock tongue 51 extending in the Y direction is also provided on the side of the magnetic latch 50, and the back side of the second lock tongue 51 abuts against the front side of the frame 10, providing another stop for the door panel 30. Since the extension direction of the second lock tongue 51 is the same as the sliding direction of the magnetic latch 50, the second lock tongue 51 slides with the magnetic latch 50 and moves in the opposite direction of its extension, thereby breaking away from the contact with the frame 10 and achieving unlocking.

[0030] Specifically, the unlocking action of the magnetic latch 50 is completed by the latch unlocking magnet on the latch (the relevant part of the latch is not shown in the figure). A latch magnet 56 with opposite poles attracted to the latch unlocking magnet is fixed on the magnetic latch 50. By bringing the latch close to the door panel 30, the latch unlocking magnet and the latch magnet 56 are attracted and aligned with each other, and the magnetic latch 50 is driven to slide and unlock, and then the door panel 30 is pushed open and inserted into the base 40. A latch torsion spring 57 is arranged on the back side of the door panel 30 to keep the magnetic latch 50 in the locked position. Therefore, when the latch magnet 56 is not subject to external attraction and the magnetic latch 50 can slide freely, the latch torsion spring 57 pushes the magnetic latch 50 to slide and lock. The magnetic latch 50 has a protrusion 54, and a groove 55 is provided on the protrusion 54. One end of the latch torsion spring 57 is inserted into the groove 55, so as to provide a restoring force for the magnetic latch 50 to the locked position through the protrusion 54.

[0031] In one embodiment, a door panel magnet 33 is further provided on the back side of the door panel 30. Correspondingly, a latch positioning magnet is also provided on the latch. The distance between the latch magnet 56 and the door panel magnet 33 is L1, and the distance between the latch unlocking magnet and the latch positioning magnet is L2. L1 is designed to be slightly larger than L2. The door panel magnet 33 is used as a reference position for latch unlocking by attracting the latch positioning magnet, so that the latch magnet 56 is more easily attracted to the unlocking position by the latch unlocking magnet.

[0032] In one embodiment, the latch magnet 56 and the door panel magnet 33 are configured as magnets with different orientations, so that the latch magnet 56 and the door panel magnet 33 can only be attracted to a unique latch magnet, ensuring that the latch can only be inserted in a unique orientation to prevent misuse.

[0033] In the specification, when an element is referred to as being “on,” “fixed” to, “coupled to” or the like, the element may be directly on, fixed to, coupled to, or contacting the other element, or intervening elements may be present.

[0034] It is to be understood that although the terms "first", "second", etc. may be used herein to describe different elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. Therefore, a first element may be referred to as a second element without departing from the teachings of the present application.
