Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a single-lock unlocking and locking mechanism. Background Technology

[0002] In existing car tray tables, the unlocking mechanism is usually single-function and simple in structure, which makes it difficult to meet the complex operation requirements of multi-functional car tray tables as well as the requirements for safety during collisions.

[0003] Some traditional unlocking mechanisms can only perform basic locking and unlocking functions, and are insufficient in terms of stability, reliability, and ease of operation. For example, they are prone to accidental unlocking or unsmooth unlocking while the vehicle is in motion. Furthermore, they cannot effectively coordinate with the various functions of the tray table, such as lifting, rotating, unfolding, and pressing down for storage, thus affecting the user experience and the overall performance of the tray table. Therefore, we propose a single-lock unlocking and locking mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a single-lock unlocking and locking mechanism to meet the needs of locking and securing multifunctional automotive internal parts. This mechanism provides reliable unlocking and locking functions in different operating states, such as rising, rotating, unfolding, and pressing down for storage. Traditional automotive tray table unlocking mechanisms can only achieve simple locking and unlocking operations, which is difficult to meet the complex usage scenarios of modern multifunctional tray tables. The unlocking mechanism of this invention can be matched with various operations of the tray table, ensuring accurate and reliable unlocking and locking at each operating state transition.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a single lock unlocking and locking mechanism, including a short plate 1, a short plate 2, a core component 1, a core component 3 and a hollow rivet, wherein the core component 1 is located on one side of the core component 3, and both the core component 1 and the core component 3 are located between the short plate 1 and the short plate 2.

[0006] The core component has a limiting groove 1, a limiting groove 2, a fastener 1, a mounting hole 1, an inner concave surface, and a beveled surface.

[0007] The core component three has a second mounting hole, a convex bevel, a pull ring, a second buckle, a third buckle, and a convex circular surface.

[0008] The first core component is movably installed between the first and second short plates through the first mounting hole, and the third core component is movably installed between the first and second short plates through the second mounting hole. The convex surface of the third core component and the concave surface of the first core component form a snap-fit, and the core components are mounted on the hollow rivet as the center of rotation, and a washer is installed at the center of rotation.

[0009] A further feature of this invention is that a groove is formed at the middle position of both the first short plate and the second short plate, and a triggering mechanism is provided at the groove. The triggering mechanism consists of a cylindrical shaft and a threaded shaft, with the threaded shaft located at one end of the cylindrical shaft and the cylindrical shaft passing through the first core component.

[0010] By adopting the above technical solution, when the rotation trajectories of the two core components reach the same rotation fulcrum and are subjected to mutual force, the force is transmitted to the center of the circle to lock it and ensure that the force is evenly distributed.

[0011] A further feature of this invention is that soft adhesive is installed in the grooves of both the first short plate and the second short plate. The soft adhesive consists of a soft adhesive surface and a snap-fit ​​groove, and the soft adhesive is installed in the groove through the snap-fit ​​groove.

[0012] By adopting the above technical solution, the soft rubber, as the noise-absorbing part between the double lock and the single lock, is injection molded onto the first and second short plates. The soft rubber mainly functions to provide a certain buffering effect when the trigger mechanism impacts the mechanism, and to prevent abnormal noises caused by the collision between metals. The soft rubber eliminates the gap between the core components on both sides of the two plates, preventing abnormal noises and shaking of the core components inside, which greatly improves the service life of the lock and the comfort of use.

[0013] A further feature of this invention is that a spring is installed on the core component, and a short locking spring and a short locking spring are respectively provided at both ends of the spring. The short locking spring is installed on the buckle of the core component, and the short locking spring is connected to the short plate.

[0014] By adopting the above technical solution, the core component is made to be in a pre-tightening force tendency to rotate to one side.

[0015] A further feature of this invention is that a spring three is installed on the core component three, and a single-lock spring one and a single-lock spring two are respectively provided at both ends of the spring three. The single-lock spring two is installed on the buckle two of the core component three, and the single-lock spring one is connected to the short plate one.

[0016] By adopting the above technical solution, the core component is in a pre-tightening force tendency to rotate inward, which gives it a springback effect, greatly reducing the shaking of the core component on the mechanism and avoiding the possibility of self-locking, thus achieving the locking state of the engagement.

[0017] A further feature of this invention is that a limiting rivet is fixedly installed on the short plate, and the limiting rivet is located between the limiting groove one and the limiting groove two.

[0018] By adopting the above technical solution, the first and second limiting grooves of the core component are secondary-limited by the limiting rivet on one side after locking, thus preventing the possibility of unlocking.

[0019] The beneficial effects of this utility model are as follows: This single-lock unlocking and locking mechanism can reliably unlock and lock in different operating states such as rising, rotating, unfolding, and pressing down for storage. This car tray unlocking mechanism can precisely lock and unlock the tray during rising, rotating, unfolding, and pressing down for storage. Through the coordinated operation of various components, the reliability and stability of the operation are ensured, preventing accidental unlocking while the vehicle is in motion and guaranteeing safety. It is easy to operate, conforms to ergonomic design, and is user-friendly. The structure is durable, easy to maintain, and improves the performance of the tray, meeting users' needs for convenience and stability. Attached Figure Description

Detailed Implementation

[0035] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] Please see Figure 1-13This utility model provides a technical solution: a single-lock unlocking and locking mechanism, comprising a first short plate 100, a second short plate 200, a first core component 300, a third core component 400, and a hollow rivet 1000. The first core component 300 is located on one side of the third core component 400, and both the first core component 300 and the third core component 400 are located between the first short plate 100 and the second short plate 200. The first core component 300 has a limiting groove 300-1 and a limiting groove 300-2. 00-2, snap-fit ​​1 300-3, mounting hole 1 300-4, concave surface 300-5, and inclined surface 300-6; the core component 3 400 begins to have mounting hole 2 400-1, convex inclined surface 400-2, pull ring position 400-3, snap-fit ​​2 400-4, snap-fit ​​3 400-5, and convex circular surface 400-6. The core component 1 300 is movably mounted between short plate 1 100 and short plate 2 200 through mounting hole 1 300-4. The core component 3 400... The core component 300-4 is movably installed between short plate 100 and short plate 200 through mounting hole 2 300-4. The convex surface 400-2 of the core component 300 and the concave surface 300-5 of the core component 300 form a snap-fit. The core component 300 and the core component 300 are installed on the hollow rivet 1000 as the center of rotation. A washer 500 is installed at the center of rotation. The hollow rivet 1000 is fixed between short plate 100 and short plate 200 by a riveting process through a limiting end installed inside the center of the core component, making the mechanism more robust. The hollow rivet 1000 serves as the rotation point of the core component and the three steps of the hollow rivet, respectively limiting the plate and the core component. The inner hole of the hollow rivet 1000 uses M4 thread and mounting screws. It can install double locks and single locks into sheet metal and other mechanical components, making it versatile. The presence of the hollow rivet 1000 reduces the amount of shaking, enhances the firmness, and stabilizes the moving mechanism.

[0037] Preferably, both short plate 100 and short plate 200 have grooves at their middle positions, and triggering mechanisms 600 are provided in the grooves. The triggering mechanism 600 consists of a cylindrical shaft 600-1 and a threaded shaft 600-2. The threaded shaft 600-2 is located at one end of the cylindrical shaft 600-1, and the cylindrical shaft 600-1 passes through the core component 300. When the rotation trajectories of the two core components reach the same rotation fulcrum, they are subjected to mutual force, which is transmitted to the center to lock them and ensure that the force is evenly distributed.

[0038] Preferably, soft rubber 700 is installed in the grooves of both short plate 100 and short plate 200. The soft rubber 700 consists of a soft rubber surface 700-2 and a snap-fit ​​groove 700-1. The soft rubber 700 is installed in the groove through the snap-fit ​​groove 700-1. The soft rubber 700 serves as a noise-absorbing part between the double lock and the single lock. It is injection molded onto short plate 100 and short plate 200 by injection molding. The soft rubber mainly functions to provide a certain buffering effect when the trigger mechanism 600 impacts the mechanism and to prevent abnormal noises caused by metal-to-metal collisions. The soft rubber eliminates the gap between the core component and the two plates on both sides, preventing abnormal noises and shaking of the core component inside, which greatly improves the service life of the lock and the comfort of use.

[0039] Preferably, a spring 800 is installed on the core component 300. Short locking spring 800-1 and short locking spring 800-2 are respectively provided at both ends of the spring 800. Short locking spring 800-1 is installed on the buckle 300-3 of the core component 300, and short locking spring 800-2 is connected to the short plate 100. The core component 300 is in a pre-tightening tendency to rotate to one side.

[0040] Preferably, a spring 1100 is installed on the core component 3 400. A single-locking spring 1 1100-1 and a single-locking spring 2 1100-2 are respectively provided at both ends of the spring 3 1100. The single-locking spring 2 1100-2 is installed on the buckle 2 400-4 of the core component 3 400. The single-locking spring 1 1100-1 is connected to the short plate 100, so that the core component 3 400 is in a pre-tightening force tendency to rotate inward, so that it has a springback effect, which greatly reduces the shaking of the core component in the mechanism and avoids the possibility of self-locking, thus realizing the engagement and locking state.

[0041] Preferably, a limiting rivet 900 is fixedly installed on the short plate 100. The limiting rivet 900 is located between the limiting groove 300-1 and the limiting groove 300-2, so that after locking, the limiting groove 300-1 and the limiting groove 300-2 of the core component 100 are limited a second time by the limiting rivet 900 on one side, preventing the possibility of unlocking.

[0042] Working principle: Before use, check the safety of each structure of this device. First... Figure 3 It is the unlocked state of a single lock. Figure 4This is the locked state of a single lock. A cylindrical shaft 600-1 serves as the trigger condition for the linkage lock. When the single lock is in the unlocked state, the cylindrical shaft 600-1 slides axially into the inclined surface 300-6 of the core component of the single lock. The three convex inclined surfaces 400-2 of the core component and the concave surface 300-5 of the core component form a latch. Then, the two core components are mounted on a hollow rivet 1000 as a rotation center. When the rotation trajectories of the two core components reach the same rotation fulcrum, they exert force on each other, transmitting the force to the center to achieve locking and ensure even force distribution. Figure 2 As shown, it is locked. After locking, the first limiting groove 300-1 and the second limiting groove 300-2 of the core component are secondary limited by the limiting rivet 900 on one side to prevent the possibility of unlocking. A spring 800 is installed on the core component 300. Short locking springs 800-1 and 800-2 are respectively provided at both ends of the spring 800. Short locking spring 800-1 is installed on the buckle 300-3 of the core component 300, and short locking spring 800-2 is connected to the short plate 100, so that the core component 300 is locked. Due to the preload tendency of rotation to one side, a spring 1100 is installed on the core component 3 400. Single-locking springs 1100-1 and 1100-2 are respectively installed at both ends of the spring 1100. Single-locking spring 1100-2 is installed on the latch 2 400-4 of the core component 3 400. Single-locking spring 1100-1 is connected to the short plate 100, causing the core component 3 400 to be in a preload tendency of inward rotation, giving it a springback effect, greatly reducing the shaking of the core component in the mechanism and avoiding the possibility of self-locking. This achieves the engaged locking state.

[0043] In the single-lock unlocking mechanism, when the single lock is in the locked state, the trigger condition for linkage unlocking is the pull ring position 400-3 under the core component 3 400. When we pull the core component 3 400 outward, the lever principle is triggered, which achieves unlocking while saving effort. The lever principle makes the convex inclined surface 400-2 of the core component 3 and the concave surface 300-5 of the core component 1 in motion trajectory. When the two core components enter their respective motion trajectories and reach the divergence point, unlocking is achieved. Under the preload of the spring 1 800, the core component 1 300 tends to rotate to both sides, and then reaches the limit rivet 900 on one side to stop the core component from rotating. Under the preload of the spring 3 1100, the core component 3 400 rotates inward and reaches the limit rivet 900 to stop it, achieving the coordinated unlocking state.
