Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts testing technology, and in particular to a quick unlocking device for the rear seat back of a car. Background Technology
[0002] In automotive seat testing, the rear seat backrest folding test is an important component. Current technology uses an unlocking cylinder and an extension cylinder to unlock and fold the backrest. However, for backrest structures that cannot automatically fold forward after unlocking, the backrest may automatically lock back after the unlocking cylinder retracts, causing unlocking failure. If the backrest fails to unlock, the extension cylinder continues to operate, potentially damaging the seat structure.
[0003] Therefore, there is an urgent need for an unlocking device that can adapt to different backrest structures and avoid accidental locking and damage, in order to solve the above-mentioned problems existing in the prior art. Utility Model Content
[0004] To address the aforementioned problems in the prior art, this utility model provides a simple, flexible, and adjustable quick-unlocking device for the rear seatback of a car.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A quick unlocking device for the rear seat back of a car includes a bracket fixedly connected to the car body. The bracket is provided with a lifting slider, the lifting slider is rotatably connected to a rotating bracket, the rotating bracket is connected to a cylinder, the output end of the cylinder is connected to an unlocking rubber block through a rubber block shaft, the cylinder is provided with a slide rail, and the unlocking rubber block moves along the slide rail.
[0007] As a preferred embodiment of this invention, the front end of the lifting slider is provided with an arc-shaped groove.
[0008] As a preferred embodiment of this invention, the unlocking rubber block can be folded upwards around the axis of rotation of the rubber block.
[0009] As a preferred embodiment of this invention, the slide is a linear guide structure, which is used to limit the left and right swing of the unlocking rubber block during the sliding process and to prevent the cylinder from rotating during the extension and retraction actions.
[0010] As a preferred embodiment of this invention, the unlocking rubber block is generally rectangular in shape.
[0011] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are:
[0012] This utility model discloses a quick unlocking device for the rear seat back of a car. By setting up a lifting slider and a rotating bracket, the angle and height of the cylinder can be flexibly adjusted to adapt to different test conditions. By setting up a rotatable unlocking rubber block, it can automatically avoid accidental locking and damage to the seat when the backrest is flipped, thus improving test efficiency and accuracy. The overall structure is simple, easy to operate, and suitable for rear seat back flipping tests of various car models. Attached Figure Description

[0017] The technical solutions of various embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0018] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. It should be pointed out that all accompanying drawings are exemplary representations. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.
[0021] Reference Figures 1 to 2 , Figure 1 This is a three-dimensional view of the application scenario of this utility model. Figure 2 This is another perspective view of the application scenario of this utility model. This utility model provides a quick unlocking device for the rear seat backrest of a car, including a bracket 1, a lifting slider 2, a rotating bracket 3, a cylinder 4, a rubber block shaft 5, an unlocking rubber block 6, and a slide rail 7. The bracket 1 is fixedly connected to the car body. The lifting slider 2 is slidably mounted on the bracket 1 and its height position can be fixed by bolts. The lifting slider 2 is rotatably connected to the rotating bracket 3. The front end of the lifting slider 2 has an arc-shaped groove 21. The angle position of the rotating bracket 3 can be fixed by bolts through the arc-shaped groove 21. The rotating bracket 3 is connected to the cylinder 4. The angle and height of the cylinder 4, which moves back and forth, depend on the lifting slider 2. The sliding block 2 and rotating bracket 3 are adjustable to adapt to the backrest unlocking position of different car models. The output end of the cylinder 4 is connected to the unlocking rubber block 6 through the rubber block pivot 5. The unlocking rubber block 6 is generally rectangular in shape and can be folded upward around the rubber block pivot 5, so that it does not interfere with the backrest during the unlocking process. The cylinder 4 is provided with a slide 7, and the unlocking rubber block 6 moves along the slide 7. The slide 7 is a linear guide structure used to limit the left and right swing of the unlocking rubber block 6 during the sliding process and to prevent the cylinder 4 from rotating during the extension and retraction actions. If it rotates, the function of the rubber block pivot 5 will be ineffective.
[0022] The following will refer to Figures 1 to 2 The working principle of this utility model will be explained.
[0023] During operation, the cylinder 4 extends, causing the unlocking rubber block 6 to move forward along the slide rail 7, thus unlocking the backrest latch. When the backrest flips over, it causes the unlocking rubber block 6 to rotate around the rubber block pivot 5, preventing interference with the backrest's movement. After the backrest separates from the unlocking rubber block 6, the unlocking rubber block 6 returns to its initial position due to gravity. Finally, the cylinder 4 retracts, the backrest flips back to its original position and locks, completing one test cycle.
[0024] This utility model discloses a quick unlocking device for the rear seat back of a car. By setting up a lifting slider and a rotating bracket, the angle and height of the cylinder can be flexibly adjusted to adapt to different test conditions. By setting up a rotatable unlocking rubber block, it can automatically avoid accidental locking and damage to the seat when the backrest is flipped, thus improving test efficiency and accuracy. The overall structure is simple, easy to operate, and suitable for rear seat back flipping tests of various car models.
[0025] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
