Technical Field

[0001] This invention relates to the field of handrail technology, specifically to a self-locking concealed handrail mechanism that can protect passengers. Background Technology

[0002] The car hovering armrest is an advanced car seat accessory that can remain suspended while the vehicle is in motion, providing hand support for the driver and passengers. This hovering armrest uses a special mechanical design that allows it to automatically adjust the position and angle of the armrest while the vehicle is in motion to maintain optimal support. At the same time, the hovering armrest can also be personalized according to the height and weight of the driver and passengers, further improving riding comfort.

[0003] Existing handrails, with their limited damping force, cannot withstand the downward acceleration on bumpy roads, and may suddenly open, injuring passengers. To address this, we propose a self-locking, concealed handrail mechanism to protect passengers. Summary of the Invention

[0004] One of the technical problems this application aims to solve is: how to prevent the handrail from suddenly opening when driving on bumpy roads.

[0005] To address the aforementioned technical problems, this application provides a self-locking concealed handrail mechanism that can protect passengers. The mechanism includes a handrail frame and further comprises: a slot, the slot being disposed on one side of the handrail frame; and a locking tongue, the locking tongue being disposed on one side of the slot. The locking tongue engages with the slot to secure a handrail locking component. The locking component is disposed on the other side of the handrail frame and is used to engage the locking tongue in an emergency to prevent the handrail from automatically springing up.

[0006] In some embodiments, the locking assembly includes an APO bracket disposed on one side of the handrail frame, with first rotating shafts disposed on both sides of the APO bracket, the latch being rotatably disposed on the APO bracket via the rotating shafts, and second rotating shafts disposed on both sides of one end of the latch, one end of the second rotating shaft being fixedly disposed on the latch, and a limiting member disposed on one side of the first rotating shaft.

[0007] In some embodiments, the limiting member includes a counterweight block disposed on one side of the first rotating shaft, a screw disposed on one side of the counterweight block, the counterweight block being fixedly connected to the locking tongue by the screw, a torsion spring being sleeved on the first rotating shaft, one end of the torsion spring being fixedly connected to the locking tongue, and the other end of the torsion spring being fixedly connected to the first rotating shaft.

[0008] In some embodiments, the handrail frame has an interior partition, and a placement member is provided on one side of the partition.

[0009] In some embodiments, the placement component includes a placement seat disposed inside the handrail frame, a displacement column on the placement seat, a connecting groove column disposed on the displacement column, a first spring disposed on the connecting groove column, a slot disposed below the connecting groove column, a spring piece disposed on one side of the slot, a displacement groove cylinder disposed below the displacement column, a slot opened on the outer side of the displacement groove cylinder, displacement tubes disposed on both sides of the displacement groove cylinder, a connecting seat disposed on each of the two displacement tubes, a displacement groove block disposed on each of the two connecting seats, a placement groove disposed on the fixed seat that matches the two connecting seats and the two displacement groove blocks, a connecting column disposed on each of the two connecting columns, a second spring disposed on each of the two connecting columns, a connecting cylinder disposed on the connecting column, a third spring disposed on the connecting cylinder, an arc-shaped piece disposed on the connecting cylinder, and a spring return element disposed at the bottom end of the spring piece.

[0010] In some embodiments, the spring-loaded member includes a push post disposed at the bottom end of the spring piece, a fourth spring disposed on the push post, and connecting strips disposed on both sides of the displacement groove cylinder.

[0011] In some embodiments, an anti-slip pad is provided on the inner side of the arc-shaped piece.

[0012] In some embodiments, the partition is made of a waterproof material.

[0013] In some embodiments, a pressure sensor is provided above the handrail, and an LED soft light is provided on the APO bracket. The LED soft light is connected to the pressure sensor via an electrical signal.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] Please see Figure 1-10 This invention provides a technical solution: a self-locking concealed handrail mechanism that can protect passengers, including a handrail frame 6, and further including: a locking hole 1, the locking hole 1 being disposed on one side of the handrail frame 6; a locking tongue 2, the locking tongue 2 being disposed on one side of a locking groove 55, the locking tongue 2 cooperating with the locking groove 55 to fix a handrail locking component 3, the locking component 3 being disposed on the other side of the handrail frame 6, the locking component 3 being used to engage the locking tongue 2 in an emergency, thereby preventing the handrail from automatically springing up, the locking component 3 including an AP0 bracket 31 disposed on one side of the handrail frame 6, a first rotating shaft 32 being disposed on both sides of the AP0 bracket 31, the locking tongue 2 being rotatably disposed on the AP0 bracket 31 via the rotating shaft, and a second rotating shaft being disposed on both sides of one end of the locking tongue 2. Shaft 33, one end of the second rotating shaft 33 is fixedly mounted on the latch 2. A limiting member 34 is provided on one side of the first rotating shaft 32. The limiting member 34 includes a counterweight 341 provided on one side of the first rotating shaft 32. A screw 342 is provided on one side of the counterweight 341. The counterweight 341 is fixedly connected to the latch 2 by the screw 342. A torsion spring 343 is sleeved on the first rotating shaft 32. One end of the torsion spring 343 is fixedly connected to the latch 2, and the other end of the torsion spring 343 is fixedly connected to the first rotating shaft 32. When the downward acceleration is greater than 10kg, the G-LOCK closing time is: when the whole vehicle has a downward acceleration of 10G: considering the influence of gravity, the inertial force F2=0.15X(10-1)X9.8=13.2N,FX 4 = 13.2 x 33 = 435.6 N / mm > T = 35 N / mm, therefore the G-LOCK will rotate and lock the armrests at an acceleration of 10G. The moment of inertia of the G-LOCK about its axis of rotation is 223.2 kg / mm. 2 The net torque is F1 × L1 - T = 435.6 Nmm - 35 Nmm = 400.6 Nmm, and the angular acceleration is (net torque ÷ moment of inertia = 400.6 Nmm ÷ 223.2 kgmm). 2=1795rad / s2", the rotation angle of the latch 2 is 7 degrees (overlap is 2mm, which is 0.122 rad in radians), and the time taken is 0.0117s. The handrail opening displacement in 0.0117s: considering the influence of gravity, the inertial force F1 = 1.4X(10-1)X 9.8 = 123.5N, F2 X L2 = 137.2X 163 = 20130.5Nmm, the handrail hinge torque T0 = 5330Nmm, so the net torque is F2×L2-T0 = 14800.5Nmm. The moment of inertia of the handrail cover about the rotation axis is 58000kgmm. 2 The angular acceleration is given by: Net torque ÷ Moment of inertia = 14800.5 N / mm ÷ 58000 kg / mm 2 =2552rad / s 2 Within 0.0117s, the armrest cover opens by 0.0175 rad, which translates to a displacement of 339 x 0.0175 = 5.9 mm at the closed position. Since 14 mm > 5.9, G-LOCK is valid.

[0032] The handrail frame 6 has an internal partition 4. A placement component 5 is located on one side of the partition 4. The placement component 5 includes a placement seat 51 located inside the handrail frame 6, a displacement column 52 on the placement seat 51, a connecting groove column 53 on the displacement column 52, a first spring 54 on the connecting groove column 53, a groove plate 518 below the connecting groove column 53, a spring piece 56 on one side of the groove plate 518, a displacement groove cylinder 57 below the displacement column 52, a slot 55 on the outer side of the displacement groove cylinder 57, and displacement tubes 58 on both sides of the displacement groove cylinder 57. Each of the two fixed bases is provided with a connecting seat 59, and each of the two connecting seats 59 is provided with a displacement groove block 510. The fixed base is provided with a placement groove 511 that matches the two connecting seats 59 and the two displacement groove blocks 510. Each of the two displacement groove blocks 510 is provided with a connecting post 512. Each of the two connecting posts 512 is provided with a second spring 513. A connecting cylinder 514 is provided on the connecting post 512. A third spring 515 is provided on the connecting cylinder 514. An arc-shaped piece 516 is provided on the connecting cylinder 514. A spring return element 517 is provided at the bottom end of the spring piece 56. The spring return element 517 includes a spring... The bottom end of the piece 56 has a push post 5171, on which a fourth spring 5172 is installed. Connecting strips 5173 are installed on both sides of the displacement groove cylinder 57. When the water cup is placed on the placement seat 51, it presses down the displacement post 52, causing the connecting groove post 53 to move downwards. This causes the connecting groove post 53 to move up and down within the groove plate 518, which in turn causes the first spring 54 to move downwards. Simultaneously, the spring piece 56 moves into the slot 55. At the same time, the displacement tube 58 causes the connecting seat 59 to slide on the displacement groove block 510, thereby moving the displacement groove block 510 into the placement groove 511. The sliding motion causes the connecting post 512 to move inward, which in turn causes the arc-shaped piece 516 to clamp the water cup inward, thus fixing the water cup. When it is necessary to remove the water cup, pressing the water cup downward causes the connecting post 53 to move the slot plate 518 horizontally, which causes the spring piece 56 to leave the slot 55. The first spring 54 and the fourth spring 5172 work together to make the device spring back. During the upward movement, the connecting seat 59 moves outward, which causes the displacement slot block 510 to move outward, which in turn causes the arc-shaped piece 516 to move outward as well, thus completing the unlocking and springback of the water cup.

[0033] An anti-slip pad is provided on the inner side of the arc-shaped piece 516 to increase the friction between the arc-shaped piece 516 and the cup.

[0034] The partition 4 is made of waterproof material. The waterproof material prevents water from flowing into the armrest 6 if the cup cap is not properly placed, thus preventing the paper products in the armrest 6 from getting wet.

[0035] A pressure sensor 7 is installed above the armrest 6, and an LED soft light 8 is installed on the AP0 bracket 31. The LED soft light 8 is connected to the pressure sensor 7 via an electrical signal. When it is nighttime or the lighting inside the car is poor, if you need to find something in the armrest 6, the LED soft light 8 will automatically turn on when the armrest is opened, making it easier to find things.

[0036] In summary, when the water cup is placed on the placement seat 51, pressing down on the displacement post 52 causes the connecting groove post 53 to move downwards, thereby causing the connecting groove post 53 to move up and down within the groove plate 518. This causes the first spring 54 to move downwards, and simultaneously, the spring piece 56 moves into the slot 55. At the same time, the displacement tube 58 causes the connecting seat 59 to slide on the displacement groove block 510, which in turn causes the displacement groove block 510 to slide within the placement groove 511. This causes the connecting post 512 to move inwards, thereby causing the arc-shaped piece 516 to clamp the water cup inwards, thus fixing the water cup in place. When it is necessary to remove the water... When the cup is pressed down, the connecting groove post 53 drives the groove plate 518 to move horizontally, so that the spring piece 56 leaves the slot 55. Then, the first spring 54 and the fourth spring 5172 exert force together to make the device spring back. During the upward movement, the connecting seat 59 moves outward, so that the displacement groove block 510 moves outward, and the arc-shaped piece 516 also moves outward, thus completing the unlocking and springback of the cup. When the acceleration is greater than 10kg, the locking tongue 2 can be fixed in the slot 55 on the handrail frame 6, so that the handrail can automatically spring up.

[0037] Example 2

[0038] Please see Figure 1-11

[0039] A groove 9 is provided on one side of the partition 4, and the placement piece 5 is placed inside the groove 9. A locking block 10 is provided at the upper end of the partition 4. Spring pieces 11 are provided on both sides of the handrail frame 6, and the locking block 10 and the spring pieces 11 cooperate with each other.

[0040] Unlike Example 1, where water spilled into the armrest box can cause water troughs to form and produce unpleasant odors if not cleaned promptly, Example 2 uses a detachable groove 9, making cleaning the groove 9 simple and quick.
