Double-chain pressing type unlocking mechanism

Abstract

The utility model discloses a double-chain pressing type unlocking mechanism which comprises a lock mechanism base, an unlocking driving piece and an unlocking driven piece. The lock mechanism base is provided with a vertical sliding groove and a transverse sliding groove which are communicated. The unlocking driving piece can slide in the vertical sliding groove, and an inclined guide part is arranged on the side, close to the transverse sliding groove, of the unlocking driving piece. The unlocking follower slides in the transverse sliding groove and comprises a left spring bolt and a right spring bolt which are connected through a pull-back spring part, and the two spring bolts are provided with sliding transmission parts matched with the oblique guide parts. When the unlocking driving piece is pressed, the inclined guide part moves downwards to enable the sliding transmission piece to drive the left and right lock tongues to return to the middle, and the return spring part is compressed; when the driving piece is loosened, the spring bolt extends out under the action of the spring, and the inclined guide part drives the driving piece to reset. The lock tongues on the two sides act at the same time, unlocking force can be borne and transmitted more evenly, and therefore the phenomenon of unlocking clamping stagnation caused by uneven distribution of force values is effectively avoided.

Description

Technical Field

[0001] This utility model relates to the field of press-to-unlock technology, specifically to a double-chain press-to-unlock mechanism. Background Technology

[0002] With the accelerating pace of automotive intelligence, in-car storage devices such as refrigerators and drawer storage boxes are becoming increasingly common in vehicles, serving as a key component in enhancing the user experience. The frequent opening and closing of these storage devices places higher demands on the performance of their unlocking mechanisms. These mechanisms must not only ensure reliable unlocking but also excel in force distribution and structural stability to guarantee smooth and stable operation of the storage devices.

[0003] Currently, most car storage box unlocking mechanisms are traditional single-chain designs. Taking patent CN207392953U as an example, it mainly consists of a bracket, an unlocking active component, an unlocking driven component, and a return spring. While it boasts advantages such as simple structure and low cost, achieving unlocking through specific grooves and pins to fulfill basic opening and closing functions, it still has some limitations in practical applications. On one hand, the single-chain structure results in a relatively concentrated force distribution, which can easily lead to uneven force distribution during long-term use, causing jamming during unlocking and affecting normal user operation. On the other hand, the stability of this mechanism has room for improvement. Faced with complex in-car environments and frequent operations, a single unlocking structure is unlikely to function consistently and stably.

[0004] Therefore, there is an urgent need for a double-chain press-type unlocking mechanism. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a double-chain press-type unlocking mechanism.

[0006] This utility model discloses a double-interlocking press-type unlocking mechanism, comprising:

[0007] A locking mechanism base includes a vertical slide groove and a transverse slide groove provided on the front side of the vertical slide groove, wherein the vertical slide groove and the transverse slide groove are connected.

[0008] The unlocking active component is slidably inserted into the vertical slide groove, and an oblique guide is provided on the side of it near the horizontal slide groove.

[0009] The unlocking follower is slidably disposed in the transverse slide groove. It includes a left locking tongue and a right locking tongue connected by a pull-back spring. Both the left locking tongue and the right locking tongue are provided with sliding transmission components that cooperate with the oblique guide portion.

[0010] Pressing the unlocking actuator causes the oblique guide to move downwards, which in turn moves the sliding transmission components on both sides, causing the left and right latches to retract along the transverse groove towards the center, compressing the pull-back spring. Releasing the unlocking actuator causes the left and right latches to extend out of the transverse groove under the action of the pull-back spring, and the oblique guide, under the movement of the sliding transmission components, causes the unlocking actuator to return to its initial position.

[0011] As a further improvement of this utility model, the transverse slide groove is provided with an observation window on the front side of the pull-back spring part.

[0012] As a further improvement of this utility model, the left locking tongue and the right locking tongue are both provided with limiting buckles near the pull-back spring portion; the limiting buckles are used to prevent the left locking tongue and the right locking tongue from dislodging from the transverse sliding groove.

[0013] As a further improvement of this utility model, the oblique guide portion includes two oblique guide blocks;

[0014] The two inclined guide blocks are symmetrically distributed in a figure-eight shape on the front of the unlocking active component, and the lower surfaces of the two inclined guide blocks form a sliding surface that cooperates with the sliding transmission components on both sides.

[0015] As a further improvement of this utility model, the sliding transmission component is a shaft pin;

[0016] The left and right locking tongues are each provided with a horizontally arranged pivot pin near the end of the pull-back spring and facing the unlocking active component; and the pivot pins on both sides cooperate with the lower surfaces of the two inclined guide blocks.

[0017] As a further improvement of this utility model, the pull-back spring part includes a guide rod and a pull-back spring;

[0018] The two ends of the guide rod are slidably connected to the left latch and the right latch, respectively, and the pull-back spring is sleeved on the guide rod between the left latch and the right latch.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model features a simple and easy-to-operate mechanism. Employing a double-locking structure, including a left and right locking tongue, the locking tongues retract towards the center through the cooperation of the unlocking actuator, the oblique guide, and the sliding transmission component. Compared to traditional single-locking structures, this double-locking structure distributes the force evenly across both locking tongues, rather than concentrating it on a single unlocking point. During unlocking, both locking tongues move simultaneously, allowing for a more even distribution of the unlocking force and effectively preventing jamming caused by uneven force distribution.

[0021] In this invention, the left and right locking tongues of the unlocking driven component are connected by a pull-back spring, and cooperate with the unlocking driving component through an oblique guide and a sliding transmission component. This multi-component cooperative structural design offers higher stability compared to the traditional single-chain unlocking method, especially in complex vehicle interior environments and with frequent operation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings:

[0036] like Figure 1-3As shown, a double-chain press-type unlocking mechanism according to this utility model includes a lock mechanism base 1, an unlocking active member 2, and an unlocking driven member 3. The lock mechanism base 1 includes a vertical slide groove 11 and a horizontal slide groove 12 provided on the front side of the vertical slide groove 11. The vertical slide groove 11 and the horizontal slide groove 12 are connected. The unlocking active member 2 is slidably inserted into the vertical slide groove 11, and an oblique guide portion is provided on the side of the active member 2 near the horizontal slide groove 12. The unlocking driven member 3 is slidably disposed in the horizontal slide groove 12. It includes a left locking tongue 31 and a right locking tongue 32 connected by a pull-back spring portion. Both the left locking tongue 31 and the right locking tongue 32 are provided with sliding transmission components that cooperate with the oblique guide portion.

[0037] Pressing the unlocking actuator 2 causes the oblique guide to move downward, which in turn moves the sliding transmission components on both sides, causing the left locking tongue 31 and the right locking tongue 32 to retract towards the center along the transverse slide groove 12, compressing the pull-back spring. Releasing the unlocking actuator 2 causes the left locking tongue 31 and the right locking tongue 32 to extend out of both ends of the transverse slide groove 12 under the action of the pull-back spring, and the oblique guide, under the movement of the sliding transmission components, causes the unlocking actuator 2 to return to its initial position.

[0038] In this embodiment, the mechanism is simple and easy to operate. It employs a double-locking structure, including a left locking tongue 31 and a right locking tongue 32. Through the cooperation of the unlocking active component 2, the oblique guide, and the sliding transmission component, the two locking tongues retract towards the center. Compared to the traditional single-locking structure, this double-locking structure distributes the force not concentrated on a single unlocking point, but rather across both locking tongues. During unlocking, both locking tongues move simultaneously, allowing for more even distribution of the unlocking force and effectively preventing unlocking jams caused by uneven force distribution. The left locking tongue 31 and right locking tongue 32 of the unlocking driven component 3 are connected by a pull-back spring and cooperate with the unlocking active component 2 through the oblique guide and the sliding transmission component. This multi-component cooperative structural design offers higher stability in complex vehicle environments and with frequent operations compared to the single unlocking method of the traditional single-locking structure.

[0039] Specifically:

[0040] like Figure 4As shown, in the above embodiment, preferably, the transverse slide 12 is provided on the front of the vertical slide 11 and in the lower middle part of the vertical slide 11; the transverse slide 12 has an observation window 13 on the front of the return spring part; the left locking tongue 31 and the right locking tongue 32 are both provided with limiting buckles 35 near the return spring part. In actual use, the limiting buckles 35 on the left locking tongue 31 and the right locking tongue 32 can be engaged with the two sides of the observation window 13 after the left locking tongue 31 and the right locking tongue 32 are extended outward and in place; in this embodiment, the limiting buckles 35 are used to prevent the left locking tongue 31 and the right locking tongue 32 from dislodging from the transverse slide 12. In this embodiment, the lock mechanism base 1 is integrally formed.

[0041] like Figure 5 As shown, in the above embodiment, preferably, the oblique guide portion is disposed on the side of the unlocking active member 2 near the transverse slide groove 12, and the oblique guide portion includes two oblique guide blocks 21. Specifically, a vertical frame is formed in the middle of the side of the unlocking active member 2 near the transverse slide groove 12 along the vertical direction, and the two oblique guide blocks 21 are symmetrically arranged on both sides of the vertical frame of the unlocking active member, and are distributed in a figure-eight symmetrical shape. The lower surface of the two oblique guide blocks 21 constitutes a sliding surface that cooperates with the sliding transmission components on both sides. In this embodiment, the unlocking active member 2 is a button bracket.

[0042] like Figure 6 As shown, in the above embodiment, preferably, the sliding transmission component is a pin 4; the left locking tongue 31 and the right locking tongue 32 are both horizontally provided with pins 4 at one end near the pull-back spring and in the direction of the unlocking active component 2; and the pins 4 on both sides cooperate with the lower surfaces of the two inclined guide blocks 21. Specifically, the pins 4 located on the left locking tongue 31 and the right locking tongue 32 are respectively placed on the lower surface of the inclined guide block 21 on the corresponding side, and can slide along the lower surface of the inclined guide block 21 as the inclined guide block 21 moves down.

[0043] In the above embodiment, preferably, the pull-back spring part includes a guide rod 33 and a pull-back spring 34; the two ends of the guide rod 33 are slidably connected to the left locking tongue 31 and the right locking tongue 32 respectively, and the pull-back spring 34 is sleeved on the guide rod 33 between the left locking tongue 31 and the right locking tongue 32.

[0044] In the above embodiments, preferably, the double-chain press-to-unlock mechanism disclosed in this embodiment can be arranged inside the product without affecting the product's appearance. By pressing the unlocking active component 2, the left locking tongue 31 and the right locking tongue 32 are retracted. When applied to a storage box, after the left locking tongue 31 and the right locking tongue 32 have retracted, the storage box can be fully opened through the built-in pop-out mechanism or the linkage mechanism.

[0045] like Figure 7-8 As shown, the usage method of this embodiment is as follows:

[0046] Initial state:

[0047] The unlocking active component 3 is located in the initial position of the vertical slide groove 11, and the oblique guide block 21 and the pin 4 are in a natural engagement state. That is, the pin 4 located on the left latch 31 and the right latch 32 is at the lowest end of the two oblique guide blocks 21 (e.g., Figure 7 As shown), at this time, under the action of the pull-back spring 34, the left locking tongue 31 and the right locking tongue 32 extend out of the two ends of the transverse slide groove 12 respectively and are inserted into the lock hole of the storage device to achieve the locking state.

[0048] Unlocking procedure:

[0049] The user presses the unlocking active component 2, causing it to slide downwards along the vertical slide groove 11;

[0050] As the unlocking active component 2 moves downward, the inclined guide blocks 21 on both sides move downward simultaneously. The two side pins 4 slide upward along the sliding surface of the inclined guide blocks 21 (as shown). Figure 8 As shown), the left locking tongue 31 and the right locking tongue 32 compress the elastic force of the pull-back spring 34, causing them to retract towards the middle of the transverse slide groove 12 and disengage from the lock hole of the storage device.

[0051] Once the left latch 31 and right latch 32 have fully retracted, the storage device can be opened freely.

[0052] Reset operation:

[0053] When the user releases the unlocking active component 2, the pull-back spring 34 releases its elastic potential energy, pushing the left locking tongue 31 and the right locking tongue 32 to extend and reset towards both ends of the transverse slide groove 12.

[0054] During the reset process of the left locking tongue 31 and the right locking tongue 32, the two side pins 4 slide downward in the opposite direction along the sliding surface of the two inclined guide blocks 21, driving the unlocking active component 2 to move upward along the vertical slide groove 11 and return to the initial position.

[0055] At this point, the left locking tongue 31 and the right locking tongue 32 are reinserted into the lock hole, the mechanism returns to the locked state, and waits for the next operation.

[0056] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
