[0001] This utility model relates to the field of automotive seat slide rail technology, and in particular to an electric slide rail lead screw bracket for automotive seats. Background Technology

[0002] A car seat rail is a mechanical component on a car seat, mainly used to adjust the position of the car seat so that it can adapt to the driving needs of different drivers and provide a more comfortable riding experience.

[0003] A Chinese patent with publication number CN217294322U discloses a lead screw bracket for an electric sliding rail of an automotive seat. The key technical points are: it includes a lead screw, a rubber pad, a retaining ring, a front bracket, a rear bracket, bolts, and a gearbox; the front bracket has a through hole; the rubber pad is inserted into the through hole of the front bracket; the front end of the lead screw is inserted into the rubber pad; the retaining ring is engaged with the front end of the lead screw; the rear end of the lead screw is inserted into the rear bracket and fixed with the bolts. Because of the insertion assembly method, no special equipment for lead screws is required, and assembly can be done manually, saving the cost of purchasing such equipment. Since a rubber pad is placed between the lead screw and the through hole of the front bracket, there is a certain floating space between the lead screw and the front bracket, reducing the downward deformation of the lead screw, maintaining the straightness of a single lead screw and the parallelism between two lead screws, reducing noise and wear of the lead screw and the gears of the reduction mechanism, thereby extending the product life.

[0004] Existing technologies often have the following drawbacks: during long-term use of the electric sliding rail screw bracket for car seats, the screw is exposed for extended periods, which can cause dust to accumulate on its surface, affecting the seat adjustment.

[0005] Therefore, this utility model provides a screw bracket for an electric slide rail of an automobile seat. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing automotive seat electric slide rail lead screw brackets, where dust tends to accumulate on the surface of the lead screw due to prolonged exposure, thus affecting the seat adjustment effect. Therefore, this invention provides an automotive seat electric slide rail lead screw bracket.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an electric sliding rail bracket for automotive seats, comprising an adjusting screw, a connecting bracket sleeved on the surface of the adjusting screw, the adjusting screw being threaded into the inner wall of the connecting bracket, a connecting hole on the surface of the connecting bracket, a dust cover sleeved on the surface of the adjusting screw, the dust cover being fixedly connected to the connecting bracket, an mounting cylinder sleeved on the surface of the adjusting screw, the mounting cylinder being fixedly connected to the dust cover, and a slidably connected stabilizing rod on the inner wall of the mounting cylinder.

[0008] The effects achieved by the above components are as follows: the dust cover can shield the adjusting screw, minimizing dust accumulation on its surface and thus maximizing the seat adjustment effect; the mounting sleeve and stabilizer bar further enhance the dust protection of the dust cover.

[0009] Preferably, a circular plate is fixedly connected to the end of the stabilizer rod away from the adjusting screw, and a second spring is sleeved on the surface of the stabilizer rod, with the two ends of the second spring fixedly connected to the mounting cylinder and the circular plate, respectively.

[0010] The effect achieved by the above components is that the second spring can be easily installed through the circular plate, and the movement of the stabilizer bar can be easily controlled. The circular plate and the second spring can limit the position of the stabilizer bar.

[0011] Preferably, the side of the connecting bracket is provided with a sliding groove, and a slider is slidably connected to the surface of the sliding groove on the connecting bracket. A connecting rod is fixedly connected to the side of the slider away from the adjusting screw.

[0012] The effect achieved by the above components is that the slider connected to the groove surface on the connecting bracket allows for a stable connection between the connecting rod and the connecting bracket while ensuring that the connecting rod can move.

[0013] Preferably, an installation rod is fixedly connected to the side of the installation cylinder, a slot is provided at one end of the installation rod near the connecting rod, and a locking block is fixedly connected to one end of the connecting rod near the installation rod, the locking block being slidably connected to the surface of the slot.

[0017] Preferably, a trapezoidal groove is provided on the side of the mounting rod near the limiting plate, a trapezoidal block is slidably connected to the surface of the trapezoidal groove, the trapezoidal block is fixedly connected to the limiting plate, and a fixing rod is slidably connected to the inner wall of the trapezoidal block, the fixing rod being fixedly connected to the surface of the trapezoidal groove.

[0018] The effect achieved by the above components is that the trapezoidal block, which is slidably connected to the surface of the trapezoidal groove, allows the limiting plate to be connected to the mounting rod, thereby limiting the position of the mounting rod by using the limiting plate.

[0019] Preferably, a first spring is fitted onto the surface of the fixing rod, and the two ends of the first spring are fixedly connected to the trapezoidal block and the mounting rod, respectively.

[0020] The effect achieved by the above components is that the fixing rod can limit the position of the first spring, and the position of the trapezoidal block can be limited by the first spring.

[0021] In summary:

[0022] In this invention, the dust cover effectively shields the adjusting screw, minimizing dust accumulation on its surface over time and ensuring optimal seat adjustment. The mounting sleeve and stabilizer ensure secure dust cover installation, while the adjustment of the connecting bracket allows for control of the dust cover's retraction and expansion. The locking block and limiting plate facilitate easy installation and removal of the mounting sleeve, making dust cover replacement convenient. Attached Figure Description

Detailed Implementation

[0028] Reference Figure 1 and Figure 4 As shown, this utility model provides a technical solution: a car seat electric slide rail screw bracket, including an adjusting screw 1, a connecting bracket 2 sleeved on the surface of the adjusting screw 1, the adjusting screw 1 being threaded into the inner wall of the connecting bracket 2, a connecting hole 3 on the surface of the connecting bracket 2, a dust cover 4 sleeved on the surface of the adjusting screw 1, the dust cover 4 being fixedly connected to the connecting bracket 2, an mounting cylinder 5 sleeved on the surface of the adjusting screw 1, the mounting cylinder 5 being fixedly connected to the dust cover 4, and a slidable stabilizing rod 16 connected to the inner wall of the mounting cylinder 5. The dust cover 4 effectively shields the adjusting screw 1, minimizing dust accumulation on its surface and thus maximizing the seat adjustment effect. The mounting cylinder 5 and the stabilizing rod 16 further ensure the dustproof effect of the dust cover 4.

[0029] The following is a detailed explanation of its overall setup and function.

[0030] Reference Figures 1-4 As shown in this embodiment: a circular plate 17 is fixedly connected to the end of the stabilizer rod 16 away from the adjusting screw 1. A second spring 18 is sleeved on the surface of the stabilizer rod 16, and both ends of the second spring 18 are fixedly connected to the mounting cylinder 5 and the circular plate 17, respectively. The circular plate 17 facilitates the installation of the second spring 18 and allows for easy control of the movement of the stabilizer rod 16. The circular plate 17 and the second spring 18 effectively limit the position of the stabilizer rod 16. A sliding groove is provided on the side of the connecting bracket 2, and a slider 8 is slidably connected to the surface of the groove. A connecting rod 6 is fixedly connected to the side of the slider 8 away from the adjusting screw 1. The slider 8 slidably connected to the surface of the groove on the connecting bracket 2 ensures a stable connection between the connecting rod 6 and the connecting bracket 2 while allowing the connecting rod 6 to move. An mounting rod 7 is fixedly connected to the side of the mounting cylinder 5. A slot 10 is provided at the end of the mounting rod 7 near the connecting rod 6, and a locking block 9 is fixedly connected to the end of the connecting rod 6 near the mounting rod 7. The locking block 9 is slidably connected to the surface of the slot 10. The mounting rod 7 can be used to connect the connecting rod 6 and the mounting cylinder 5, thereby ensuring the installation effect of the mounting cylinder 5.

[0031] A limiting plate 13 is slidably connected to the side of the mounting rod 7 near the adjusting screw 1, and the limiting plate 13 is tightly fitted with the locking block 9. The limiting plate 13 and the locking block 9 ensure the stability of the mounting rod 7 during installation. A trapezoidal groove 11 is formed on the side of the mounting rod 7 near the limiting plate 13. A trapezoidal block 12 is slidably connected to the surface of the trapezoidal groove 11, and the trapezoidal block 12 is fixedly connected to the limiting plate 13. A fixing rod 14 is slidably connected to the inner wall of the trapezoidal block 12, and the fixing rod 14 is fixedly connected to the surface of the trapezoidal groove 11. The trapezoidal block 12 slidably connected to the surface of the trapezoidal groove 11 allows the limiting plate 13 to be connected to the mounting rod 7, thereby restricting the position of the mounting rod 7. A first spring 15 is sleeved on the surface of the fixing rod 14, and both ends of the first spring 15 are fixedly connected to the trapezoidal block 12 and the mounting rod 7, respectively. The fixing rod 14 restricts the position of the first spring 15, thus restricting the position of the trapezoidal block 12.

[0032] Working principle: Before installing the adjusting screw 1 and connecting bracket 2, move the dust cover 4 closer to the adjusting screw, then connect the dust cover 4 and connecting bracket 2. Pull the circular plate 17 to make the stabilizing rod 16 slide on the inner wall of the mounting cylinder 5, causing the circular plate 17 to move away from the mounting cylinder 5. Push the limiting plate 13 to make the trapezoidal block 12 slide on the trapezoidal groove 11 surface on the mounting rod 7, causing the first spring 15 to contract. Move the mounting cylinder 5 closer to the dust cover 4, release the circular plate 17, and under the action of the second spring 18, the stabilizing rod 16 moves closer to the adjusting screw 1, making contact with the teeth of the adjusting screw 1. Then connect the mounting cylinder 5 and the dust cover 4. At this time, the locking block 9 is on the locking groove 10 surface on the mounting rod 7. Release the limiting plate 13, and under the action of the first spring 15, the limiting plate 13 moves closer to the locking block 9, completing the connection between the mounting rod 7 and the connecting rod 6. Through the fixed rod 14, the first... The position of spring 15 serves as a limiting factor, and the seat can then be installed through the connecting hole 3. When the driving adjustment screw 1 moves the connecting bracket 2, the adjustment screw 1 moves the position of the mounting cylinder 5 through the stabilizing rod 16. As a result, the mounting cylinder 5 pushes the connecting rod 6 through the mounting rod 7, causing the slider 8 to slide on the groove surface of the connecting bracket 2. The dust cover 4 can shield the adjustment screw 1, minimizing dust accumulation on its surface over long-term use and ensuring the best possible adjustment of the seat. The mounting cylinder 5 and stabilizing rod 16 ensure the installation of the dust cover 4 and allow the adjustment of the connecting bracket 2 to control the retraction or expansion of the dust cover 4. The locking block 9 and limiting plate 13 facilitate the installation and removal of the mounting cylinder 5, making it easy to replace the dust cover 4.
