Description

Technical Field

[0001] This invention belongs to the field of electric slide rail technology, and specifically relates to an electric slide rail device for automobile seats. Background Technology

[0002] Electric sliding rails are now used in many industries such as medical, automotive and construction, utilizing their automatic movement to achieve the desired purpose. For example, electric sliding rails are used in aircraft seats in cars to move and improve comfort.

[0003] However, in practice, when electric sliding rails are used in a car for extended periods, a large amount of debris and impurities can easily accumulate inside the rails. Over time, this can obstruct the sliders and severely affect the flexibility of seat position adjustments.

[0004] Therefore, there is a need for an electric sliding rail device for car seats to solve the problem that in existing electric sliding rails, when used in a car for a long time, a large amount of debris and impurities can easily enter the inner side of the rail, which will cause obstruction to the slider over time. Summary of the Invention

[0005] The purpose of this invention is to provide an electric sliding rail device for automobile seats to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electric slide rail device for automobile seats, comprising two symmetrically distributed electric slide rails, a seat support plate transversely disposed between the two electric slide rails, and an electric slider slidably disposed inside the electric slide rails and perpendicularly fixed to the end of the seat support plate. Both ends of the electric slide rails are provided with shielding and protective mechanisms, and both sides of the electric slider located inside the electric slide rails are provided with shaking mechanisms.

[0007] The shielding and protection mechanism includes a fixed frame fixed in a C-shape to the top surface of the electric slide rail, a second winding rod rotatably disposed in the inner walls on both sides of the fixed frame, and a first winding rod detachably disposed between the two second winding rods. The first winding rod is located inside the fixed frame, and a shielding cloth is wound around the rod body of the first winding rod. The end of the shielding cloth is detachably connected to the side wall of the electric slider, and the shielding cloth covers the opening of the electric slide rail. The second winding rod is provided with an elastic winding component on its rod body located outside the fixed frame.

[0008] The shaking mechanism includes a movable cylinder with one end open and vertically disposed inside the electric slide rail, and an impact rod vertically slidably disposed inside the movable cylinder. The movable cylinder is fixedly connected to the side wall of the electric slider through a bracket. One end of the impact rod passes through the opening of the movable cylinder and is fixed with an impact ball that abuts against the bottom surface of the shielding cloth.

[0009] It should be noted in the solution that the elastic winding component includes a fixed cylinder sleeved on the body of the second winding rod and vertically fixed to the side wall of the fixed frame. A torsion spring located inside the fixed cylinder is also sleeved on the body of the second winding rod. One end of the torsion spring is fixedly connected to the body of the second winding rod, and the other end of the torsion spring is fixedly connected to the inner wall of the fixed cylinder.

[0010] It is worth noting that the other end of the impact rod extends out of the movable cylinder and is fixed with a first magnetic block, while several second magnetic blocks are equidistantly embedded on the inner wall of the bottom end of the electric slide rail.

[0011] Furthermore, it should be noted that a return spring is sleeved on the rod body located inside the movable cylinder of the impact rod. One end of the return spring is fixedly connected to the rod body of the impact rod, and the other end of the return spring is fixed with a pull ring, which is tightly sleeved on the rod body of the impact rod.

[0012] In a preferred embodiment, a first fixing block is fixed to the end of the first winding rod, and a second fixing block that is fixed to the end of the second winding rod is attached to the bottom surface of the first fixing block.

[0013] In a preferred embodiment, a locking stud that is fixed to the second fixing block is passed through the top of the first fixing block, and a locking nut that abuts against the first fixing block is threaded onto the shaft of the locking stud.

[0014] In a preferred embodiment, the side wall of the electric slider is vertically fixed with a fixing plate that fits against the bottom surface of the shielding cloth, the top surface of the shielding cloth is provided with a fixing stud, and the fixing plate is provided with a threaded hole that mates with the fixing stud.

[0015] Compared with the prior art, the electric sliding rail device for automobile seats provided by the present invention has at least the following beneficial effects:

[0016] (1) By setting up a shielding and protective mechanism, the electric slide rail can effectively cooperate with the electric slider during the use of the electric slide rail in the vehicle, and ensure the sealing effect inside the electric slide rail in real time to prevent impurities in the vehicle from entering the electric slide rail. This enhances the practicality of the device to a certain extent and ensures the flexibility of the electric slider during the movement.

[0017] (2) By setting up the shaking mechanism, when the electric slider moves inside the electric slide rail, the shaking mechanism can simultaneously and continuously vibrate the shielding cloth in the shielding and protection mechanism, causing the shielding cloth to shake. This can effectively shake off the impurities distributed on the shielding cloth, so as to prevent solid impurities from being wrapped in the shielding cloth along with the shielding cloth, tearing the shielding cloth and affecting the service life of the shielding cloth.

[0025] Please see Figure 1-6 The present invention provides an electric slide rail device for an automobile seat, including two symmetrically distributed electric slide rails 1, a seat support plate 3 transversely arranged between the two electric slide rails 1, and an electric slider 2 slidably arranged inside the electric slide rails 1 and perpendicularly fixed to the end of the seat support plate 3.

[0026] When in use, the seat is installed on the seat support plate 3. When the electric slide rail 1 is opened, the electric slider 2 can slide inside the electric slide rail 1, thereby effectively adjusting the position of the seat support plate 3 and the seat.

[0027] However, in practice, when the electric slide rail 1 is used in the car for a long time, a lot of debris and impurities are likely to enter the inside of the electric slide rail 1. Over time, this will obstruct the electric slider 2 and seriously affect the flexibility of seat position adjustment.

[0028] In view of this, such as Figure 1-3 As shown, it is worth noting that both ends of the electric slide rail 1 are equipped with shielding and protective mechanisms.

[0029] By setting up a shielding and protective mechanism, the electric slide rail 1 can effectively cooperate with the electric slider 2 during use inside the vehicle, ensuring the sealing effect inside the electric slide rail 1 in real time, preventing impurities inside the vehicle from entering the electric slide rail 1, thereby enhancing the practicality of the device to a certain extent and ensuring the flexibility of the electric slider 2 during operation.

[0030] Furthermore, such as Figure 3 and Figure 6 As shown, it is worth noting that the shielding and protection mechanism includes a fixed frame 4 fixed in a C-shape on the top surface of the electric slide rail 1, a second winding rod 8 rotatably disposed in the inner walls on both sides of the fixed frame 4, and a first winding rod 5 detachably disposed between the two second winding rods 8. The first winding rod 5 is located inside the fixed frame 4, and a shielding cloth 6 is wound around the rod body of the first winding rod 5. The end of the shielding cloth 6 is detachably connected to the side wall of the electric slider 2, and the shielding cloth 6 covers the opening of the electric slide rail 1. The second winding rod 8 is provided with an elastic winding component on the rod body located outside the fixed frame 4.

[0031] The elastic winding component includes a fixed cylinder 7 sleeved on the body of the second winding rod 8 and vertically fixed to the side wall of the fixed frame 4. A torsion spring 9 located inside the fixed cylinder 7 is also sleeved on the body of the second winding rod 8. One end of the torsion spring 9 is fixedly connected to the body of the second winding rod 8, and the other end of the torsion spring 9 is fixedly connected to the inner wall of the fixed cylinder 7.

[0032] When the electric slider 2 slides within the electric slide rail 1, it can apply a pulling force to one set of shielding cloths 6 and release the pulling force to the other set of shielding cloths 6. When the shielding cloths 6 are pulled, they can quickly extend outward from the fixed frame 4. During the continuous extension process, the first winding rod 5 and the second winding rod 8 are driven to rotate. The second winding rod 8 twists the torsion spring 9, causing the torsion spring 9 to deform. Conversely, when the pulling force on the shielding cloths 6 is released, the second winding rod 8 can rotate in the opposite direction under the action of the torsion force of the torsion spring 9, automatically winding up the shielding cloths 6. Thus, the two sets of shielding cloths 6 can extend and retract simultaneously with the displacement of the electric slider 2, covering the opening of the electric slide rail 1 in real time and ensuring the internal sealing of the electric slide rail 1.

[0033] Furthermore, such as Figure 3 and Figure 4 As shown, it is worth noting that the electric slider 2 is equipped with a shaking mechanism on both sides inside the electric slide rail 1.

[0034] By setting up a shaking mechanism, when the electric slider 2 moves inside the electric slide rail 1, the shaking mechanism can simultaneously and continuously vibrate the shielding cloth 6 in the shielding and protective mechanism, causing the shielding cloth 6 to shake. This can effectively shake off the impurities distributed on the shielding cloth 6, so as to prevent solid impurities from being wrapped inside the shielding cloth 6 along with the winding of the shielding cloth 6, which would tear the shielding cloth 6 and affect its service life.

[0035] Furthermore, such as Figure 4 As shown, it is worth noting that the shaking mechanism includes a movable cylinder 16 with one end open and vertically arranged inside the electric slide rail 1, and an impact rod 17 vertically slidably arranged inside the movable cylinder 16. The movable cylinder 16 is fixedly connected to the side wall of the electric slider 2 through a bracket. One end of the impact rod 17 passes through the opening of the movable cylinder 16 and is fixed with an impact ball 18 that abuts against the bottom surface of the shielding cloth 6.

[0036] The other end of the impact rod 17 extends out of the movable cylinder 16 and is fixed with a first magnetic block 19. Several second magnetic blocks 20 are fixedly embedded at equal intervals on the inner wall of the bottom end of the electric slide rail 1.

[0037] A return spring 22 is fitted on the rod body of the impact rod 17 located inside the movable cylinder 16. One end of the return spring 22 is fixedly connected to the rod body of the impact rod 17, and the other end of the return spring 22 is fixed with a pull ring 21, which is tightly fitted onto the rod body of the impact rod 17.

[0038] During the sliding of the electric slider 2, the electric slider 2 can simultaneously carry the movable cylinder 16 to move together. In this way, the first magnetic block 19 can pass through multiple second magnetic blocks 20 in sequence. When the first magnetic block 19 moves to the position corresponding to the second magnetic block 20, the first magnetic block 19 is pushed upward by the repulsive force of the impact rod 17, causing the impact ball 18 to impact the barrier cloth 6. During this process, the impact rod 17 can simultaneously move the pull ring 21 upward, causing the pull ring 21 to pull the return spring 22 to deform. Then, using the rebound force of the return spring 22, when the first magnetic block 19 moves to a position that is not corresponding to the second magnetic block 20, the repulsive force between the two disappears. The pull ring 21 can then carry the impact rod 17 to quickly return to its original position and slide down under the action of the return spring 22, so as to reset the impact ball 18 and facilitate secondary use. Thus, when the first magnetic block 19 passes through multiple second magnetic blocks 20 in sequence, the impact rod 17 and the impact ball 18 can slide up and down to impact the barrier cloth 6, causing the barrier cloth 6 to shake.

[0039] Furthermore, such as Figure 3-5As shown, it is worth noting that the end of the first winding rod 5 is fixed with a first fixing block 10, the bottom surface of the first fixing block 10 is fitted with a second fixing block 11 which is fixed to the end of the second winding rod 8, the top of the first fixing block 10 is penetrated by a locking stud 12 which is fixed to the second fixing block 11, and the rod body of the locking stud 12 is threaded with a locking nut 13 that abuts against the first fixing block 10;

[0040] The side wall of the electric slider 2 is vertically fixed with a fixing plate 14 that fits against the bottom surface of the shielding cloth 6. A fixing stud 15 is passed through the top surface of the shielding cloth 6. A threaded hole that mates with the fixing stud 15 is opened on the fixing plate 14.

[0041] When the barrier cloth 6 becomes damaged after long-term use, the operator only needs to tighten the locking nut 13 and the fixing stud 15 separately. This will cause the locking nut 13 to retract from the locking stud 12 in the threaded structure, thereby releasing the fixing effect between the first fixing block 10 and the second fixing block 11. This will make it easy for the operator to remove the first winding rod 5 and the barrier cloth 6 as a whole from the inside of the fixing frame 4. It will also cause the fixing stud 15 to retract from the threaded hole on the fixing plate 14 in the threaded structure. This will break the fixing effect between the end of the barrier cloth 6 and the fixing plate 14, making it easy for the operator to replace the first winding rod 5 and the barrier cloth 6 as a whole.

[0042] In summary: By setting up the shielding and protective mechanism, the electric slide rail 1 can effectively cooperate with the electric slider 2 during use inside the vehicle, ensuring the sealing effect inside the electric slide rail 1 in real time, preventing impurities from entering the electric slide rail 1. This enhances the practicality of the device to a certain extent and ensures the flexibility of the electric slider 2 during movement. Through the setting of the shaking mechanism, when the electric slider 2 moves inside the electric slide rail 1, the shaking mechanism can simultaneously and continuously vibrate the shielding cloth 6 in the shielding and protective mechanism, causing the shielding cloth 6 to shake. This can effectively shake off the impurities distributed on the shielding cloth 6, preventing solid impurities from being wrapped up with the shielding cloth 6 and being trapped inside the shielding cloth 6, which would tear the shielding cloth 6 and affect its service life.
