[0014] Preferably, a second core component convex circular surface, a second core component end, a second core component outer circular part, and a second core component straight surface are provided on the outer surface of the second core component.

[0023] Compared with the prior art, the present invention provides a double-lock unlocking and locking mechanism, which has the following beneficial effects:

[0024] The double-lock unlocking and locking mechanism can provide reliable unlocking and locking functions for different operating states such as rising, rotating, unfolding, and pressing and storing. The unlocking mechanism of the car small table board can accurately realize the locking and unlocking of the operations of the small table board rising, rotating, unfolding, and pressing and storing. Through the cooperation of each component, the reliability and stability of the operation are ensured, accidental unlocking during vehicle driving is avoided, and the use safety is guaranteed. The operation is convenient, in line with the ergonomic design, and the user can operate easily. The structure is durable and easy to maintain, improving the performance of the small table board and meeting the user's requirements for convenience and stability.

[0025] The double-lock unlocking and locking mechanism uses two trigger cylindrical shafts as the triggering conditions for linkage locking. When the double-lock is in the unlocked state, when the two trigger cylindrical shafts slide into the narrow U-shaped groove through axial movement, a buckle is formed between the convex circular surface of the second core part and the concave surface of the first core part. Then, through the first core part and the second core part, it is installed on the first hollow rivet as the rotation center. When the maximum inscribed point (the tangent point of the first core part) of the first core part is tangent to the outer circular part of the second core part, the same rotation fulcrums receive force from each other, transmitting the force to the center to achieve locking and uniform force distribution. The double-lock effectively prevents unilateral rotation.

[0026] For the double-lock unlocking and locking mechanism, when the double-lock is in the locked state, the triggering condition for linkage unlocking is the end of the second core part. Since all the core parts and spring pins are in a mirror state when looking at both sides with the double-lock separated in the middle, depending on the customer's requirements, this mechanism can achieve unlocking on both sides with only one triggering condition, and there is also one triggering condition on each side, that is, the two triggering conditions unlock separately.

[0027] When pressing down on the end of the second core part together, the end of the second core part triggers the lever principle, making it more labor-saving while achieving unlocking. The lever principle causes the convex circular surface of the second core part and the concave surface of the first core part to be in the movement trajectory. When the two core parts enter their respective movement trajectories and reach the divergence point, unlocking is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] Please refer to Figure 1-18 , a double-lock unlocking and locking mechanism, including a double-lock long plate 100, two double-lock short plates 200 and two sets of locking components.

[0065] Two short plate outer rivet installation holes 200-1, short plate U-shaped grooves 200-2, short plate inner rivet installation holes 200-3, short plate first hollow rivet installation holes 200-4 and short plate second hollow rivet installation holes 200-5 are provided on the outer surfaces of the two double-lock short plates 200;

[0066] The two-side rivets 500 are installed between the long plate outer rivet installation hole 100-1 and the short plate outer rivet installation hole 200-1. The inner rivets 900 are installed between the inner rivet long plate installation hole 100-5 and the short plate inner rivet installation hole 200-3. The first hollow rivet 1000 is installed between the first hollow rivet long plate installation hole 100-8 and the short plate second hollow rivet installation hole 200-5. The second hollow rivet 1300 is installed between the second hollow rivet long plate installation hole 100-6 and the short plate second hollow rivet installation hole 200-5. The long plate U-shaped groove 100-7 corresponds to the short plate U-shaped groove 200-2.

[0067] A wide U-shaped groove 300-1, a first spring buckle position 300-3, a second hollow rivet installation hole 300-4 and a narrow U-shaped groove 300-6 are provided on the outer surface of the first core component 300. A v-shaped opening is provided on the outer surface of the first core component 300. The inner wall of the v-shaped opening is the first core component concave surface 300-5. A first core component tangent point part 300-2 is provided on the outer surface of the first core component 300;

[0068] The two-side rivets 500 are located in the wide U-shaped groove 300-1. The second hollow rivet 1300 passes through the second hollow rivet installation hole 300-4. The narrow U-shaped groove 300-6 corresponds to the long plate U-shaped groove 100-7.

[0069] The outer surface of the second core member 400 is provided with a second core member convex circular surface 400-1, a second core member end 400-3 and a second core member straight surface 400-5. A first hollow rivet core member mounting hole 400-2 is formed on the outer surface of the second core member 400. A protrusion is provided on the outer surface of the second core member 400, and the outer surface of the protrusion is arc-shaped, which is set as the second spring buckle position 400-4;

[0070] The second core member convex circular surface 400-1 corresponds to the first core member concave surface 300-5, and the first hollow rivet 100 penetrates through the first hollow rivet core member mounting hole 400-2.

[0071] For the double-lock locking mechanism part, first Figure 3 is the unlocked state of the double lock, Figure 4 is the locked state of the double lock. Through two trigger cylindrical shafts 600 as the trigger conditions for linkage locking, when the double lock is in the unlocked state, when the two trigger cylindrical shafts 600 slide into the narrow U-shaped groove 300-6 through axial movement, the second core member convex circular surface 400-1 and the first core member concave surface 300-5 form a buckle. Then, through the first core member 300 and the second core member 400, it is installed on the first hollow rivet 1000 as the rotation center. When the maximum inscribed point of the first core member, the first core member tangent part 300-2, is tangent to the outer circle part 400-6 of the second core member, the same rotation fulcrum is stressed, and the force is transmitted to the center to make it lock and the force is evenly distributed. The double lock effectively prevents unilateral rotation.

[0072] The two-side rivets 500 include two-side rivet outer circle parts 500-2 and two-side rivet end parts 500-1. The diameter of the two-side rivet outer circle parts 500-2 is greater than that of the two-side rivet end parts 500-1;

[0073] The inner side rivets 900 include inner side rivet outer circle parts 900-1 and inner side rivet end parts 900-2. The diameter of the inner side rivet outer circle parts 900-1 is greater than that of the inner side rivet end parts 900-2.

[0074] Embodiment 2: The difference between this embodiment and Embodiment 1 is that, among them, the trigger cylindrical shaft 600 includes a cylindrical shaft body 600-1. One end of the cylindrical shaft body 600-1 is provided with a hexagonal hole groove, and a trigger cylindrical shaft spring 600-2 is installed at the other end of the cylindrical shaft body 600-1.

[0075] For the double-lock unlocking mechanism part, when the double lock is in the locked state, the trigger condition for linkage unlocking is the second core member end 400-3. Since when looking at all the core members and spring pins from the middle of the double lock to both sides, they are in a mirror state, depending on the customer's requirements, this mechanism can achieve unlocking on both sides with only one trigger condition, and there is one trigger condition on both sides, that is, the two trigger conditions are unlocked separately;

[0076] When the second core component end 400-3 is pressed down together, the second core component end 400-3 triggers the lever principle, which makes unlocking more labor-saving. The lever principle makes the convex surface 400-1 of the second core component and the concave surface 300-5 of the first core component in the motion trajectory. When the two core components enter their own motion trajectories respectively, they reach the divergence point to achieve unlocking.

[0077] Under the preload of the first spring 1200, the first core component 300 tends to rotate to both sides, and then reaches the outer circumference 500-2 of the rivets on both sides to stop the core component from rotating. Under the preload of the second spring 1100, the second core component 400 tends to rotate to both sides, and reaches the inner rivet outer circumference 900-1 to stop it. The unlocked state is realized.

[0078] Embodiment 3: The difference between this embodiment and embodiment 1 is that, the soft glue 700 includes a soft glue surface 700 - 2 and a soft glue block 700 - 1 , and the soft glue 700 is installed on the soft glue installation hole 100 - 3 .

[0079] The soft rubber 700 serves as the silencer part between the double lock and the single lock. The soft rubber block 700-1 is injected on the soft rubber mounting hole by injection molding. The soft rubber 700 mainly functions to trigger the impact of the cylindrical shaft 600 on the mechanism. The soft rubber surface 700-2 has a certain buffering effect and prevents abnormal noise caused by collision between metal and metal. The two sides of the soft rubber eliminate the gap between the core parts in the two plates to prevent the core parts from shaking with abnormal noise, which greatly improves the service life of the lock function and the comfort of use.

[0080] Embodiment 4: The difference between this embodiment and embodiment 1 is that, the second spring 1100 includes a second spring head end 1100-1 and a second spring tail end 1100-2, the second spring tail end 1100-2 is installed in the second spring buckle position 400-4, and the second spring head end 1100-1 is installed in the second spring long plate installation opening 100-4;

[0081] The first spring 1200 includes a first spring head end 1200-1 and a first spring tail end 1200-2. The first spring tail end 1100-2 is installed in the first spring buckle position 300-3, and the first spring head end 1100-1 is installed in the first spring long plate installation opening 100-2.

[0082] After locking, the wide U-shaped groove 300-1 is secondarily limited by the outer circular parts 500-2 of the two-sided rivets, preventing the possibility of unlocking. The first end 1200-1 of the first spring is installed into the first spring long plate installation opening 100-2, and the second end 1200-2 of the first spring is installed onto the first spring buckling position 300-3 of the double-lock long plate 100. After installation, the pre-tightening force of the first spring 1200 causes the first core part 300 to have a pre-tightening force tendency in the open state, greatly reducing the sway of the first core part 300 on the mechanism and avoiding the possibility of self-locking.

[0083] The second end 1100-2 of the second spring is installed onto the second spring buckling position 400-4, and the first end 1100-1 of the second spring is buckled onto the second spring long plate installation opening 100-4, causing the second core part 400 to have a pre-tightening force tendency to rotate to both sides, greatly reducing the sway and self-locking possibility of the second core part 400 on the mechanism. Looking at all the core parts and spring pins from the middle of the double-lock to both sides, they are in a mirror state, so it can achieve the function of synchronously locking one side or both sides with extremely high synchronism and achieve the cooperative locking state.

[0084] Embodiment 5: The first hollow rivet 1000 is in a multi-layer stepped shape, and is successively set as the first hollow rivet layer 1000-1, the second hollow rivet layer 1000-2, the third hollow rivet layer 1000-3, and the fourth hollow rivet layer 1000-4 according to the diameter size. The outer surface of the fourth hollow rivet layer 1000-4 is provided with a hollow rivet opening 1000-5.

[0085] The first hollow rivet 1000 is fixed between the double-lock long plate 1 and the double-lock short plate 2 by installing one end inside the center of the core part and limiting the other end by riveting process, making the mechanism parts more firm. The first hollow rivet layer 1000-1, the second hollow rivet layer 1000-2, and the third hollow rivet layer 1000-3 respectively play a limiting role with the plate and the core part as the rotation point of the core part. The inner hole of the first hollow rivet uses M4 thread to install screws, and the double-lock and single-lock can be installed into the sheet metal and other mechanism parts, making it widely used. The existence of the hollow rivet reduces the sway amount, enhances the firmness, and stabilizes the motion mechanism.

[0086] In summary, the double-lock unlocking and locking mechanism can provide reliable unlocking and locking functions for different operating states such as rising, rotating, unfolding, and pressing down for storage, etc. The unlocking mechanism of the automotive small table board can accurately achieve the locking and unlocking of the operations of the small table board rising, rotating, unfolding, and pressing down for storage. Through the cooperation of various components, the reliability and stability of the operation are ensured, accidental unlocking during vehicle driving is avoided, and the use safety is guaranteed. The operation is convenient, conforms to the ergonomic design, and the user can operate easily. The structure is durable, easy to maintain, improves the performance of the small table board, and meets the user's requirements for convenience and stability.

[0087] With the two trigger cylindrical shafts 600 as the trigger conditions for interlocking locking, when the double lock is in the unlocked state, the two trigger cylindrical shafts 600 slide into the narrow U-shaped grooves 300-6 through axial movement. At this time, the convex circular surface 400-1 of the second core part forms a buckle with the concave surface 300-5 of the first core part. Then, through the first core part 300 and the second core part 400, it is installed on the first hollow rivet 1000 as the rotation center. When the maximum inscribed point of the first core part, the tangent point part 300-2 of the first core part, is tangent to the outer circular part 400-6 of the second core part, the same rotation fulcrum is stressed mutually, and the force is transmitted to the center to make it lock and the force is evenly distributed. The double lock effectively prevents unilateral rotation.

[0088] When the double lock is in the locked state, the trigger condition for interlocking unlocking is the end 400-3 of the second core part. Since all the core parts and spring pins are in a mirror state when looking at both sides from the middle of the double lock, depending on the customer's requirements, this mechanism can achieve unlocking on both sides with only one trigger condition, and there is also one trigger condition on each side, that is, the two trigger conditions are unlocked separately.

[0089] When pressing down the end 400-3 of the second core part together, the end 400-3 of the second core part triggers the lever principle, making it more labor-saving while unlocking. The lever principle makes the convex circular surface 400-1 of the second core part and the concave surface 300-5 of the first core part in the movement track. When the two core parts enter their respective movement tracks and reach the divergence point, unlocking is achieved.
