[0036] The sliding motion mechanism of this utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0037] Please refer to Figures 1 to 2 In a preferred embodiment, the sliding motion mechanism of this utility model includes a lead screw 1 and a sliding bracket 2. The sliding bracket 2 is provided with a first slider 201 and a second slider 202. The first slider 201 is sleeved on the lead screw 1 and threadedly connected to the lead screw 1. A slide rail 3 is provided on one side of the lead screw 1. The slide rail 3 is arranged parallel to the lead screw 1. The slide rail 3 is provided with a groove 301 for the second slider 202 to extend into. At least one side of the second slider 202 facing the groove 301 is provided with a friction rod 4. The second slider 202 is slidably connected to the slide rail 3 through the friction rod 4. A drive assembly 5 is provided at one end of the lead screw 1. The output end of the drive assembly 5 is connected to the lead screw 1 to drive the lead screw 1 to rotate, thereby realizing the axial movement of the first slider 201 along the lead screw 1.

[0038] Specifically, the output end of the drive component 5 is connected to the lead screw 1. When the drive component 5 is activated, it drives the lead screw 1 to rotate. Since the first slider 201 is threadedly connected to the lead screw 1, when the lead screw 1 rotates, the first slider 201 moves along the axial direction of the lead screw 1, thereby realizing the sliding of the sliding bracket 2. At the same time, the second slider 202 has a friction rod 4 on at least one side facing the slide groove 301. That is, the second slider 202 on the sliding bracket 2 has a friction rod 4 between it and the slide rail 3. The second slider 202 can be slidably connected to the slide rail 3 through the friction rod 4. This sliding provides additional stable support for the sliding bracket 2, preventing the sliding bracket 2 from shaking or shifting during the sliding process. The setting of the friction rod 4 reduces the direct friction between the second slider 202 and the slide rail 3, reduces noise during the sliding process, and improves the user experience.

[0039] Please refer to Figure 1 andFigure 3 In some embodiments of the utility model, drive assembly 5 includes driving part 501, gear set 502 and matching gear 503, the output end of driving part 501 is connected with worm 5011, worm 5011 is engaged with gear set 502, and matching gear 503 is fixed on screw rod 1 and is engaged with gear set 502. Through the cooperative work of driving part 501, gear set 502 and matching gear 503, efficient transmission from driving part 501 to screw rod 1 is realized. This transmission mode has the characteristics of stable transmission ratio and strong carrying capacity. At the same time, the engagement of worm 5011 and gear set 502 has self-locking characteristics, that is, when the external load is too large or driving part 501 stops working, worm 5011 can be automatically locked, preventing screw rod 1 and the load from moving accidentally, and improving the safety of the system. Specifically, when driving part 501 starts, its output end starts to rotate. The output end of driving part 501 is connected with worm 5011, so worm 5011 will rotate with driving part 501. Worm 5011 is engaged with a gear in gear set 502, and when worm 5011 rotates, it will drive the gear to rotate. Gear set is usually composed of multiple gears, and different gear ratios are used to achieve speed reduction or speed increase. Matching gear 503 is fixed on screw rod 1 and is engaged with another gear in gear set 502. When a gear in gear set 502 rotates, it will drive matching gear 503 and screw rod 1 to rotate together. Since the first sliding block 201 is threadedly connected with the screw rod 1, when the screw rod 1 rotates, the first sliding block 201 will move along the axial direction of the screw rod 1. At the same time, the second sliding block 202 slides on the slide rail 3 through the friction rod 4, providing additional support and guidance for the sliding bracket 2. The load connected to the sliding bracket 2 (such as a vehicle-mounted central control screen) will move with the first sliding block 201, thereby realizing sliding movement.

[0040] Specifically, gear set 502 includes first gear 5021 and second gear 5022 coaxially connected with first gear 5021, first gear 5021 is engaged with worm 5011, and second gear 5022 is engaged with matching gear 503. Worm 5011 is engaged with first gear 5021, and when worm 5011 rotates, it will drive first gear 5021 to rotate. First gear 5021 is coaxially connected with second gear 5022, so when first gear 5021 rotates, second gear 5022 will also rotate synchronously. Second gear 5022 is engaged with matching gear 503, and when second gear 5022 rotates, it will drive matching gear 503 and screw rod 1 to rotate together. Matching gear 503 is fixed on screw rod 1, so the rotation of screw rod 1 will directly cause the movement of first sliding block 201.

[0041] Further, please refer to Figure 1, the end of the screw rod 1 away from the mating gear 503 is provided with a screw rod support 101, the screw rod 1 is provided in the screw rod support 101 and is rotationally connected with the screw rod support 101. The screw rod support 101 provides additional support for the screw rod 1, thereby enhancing the stability of the entire sliding movement mechanism. Since the screw rod 1 is stably supported, the first sliding block 201 can be accurately moved along the axial direction of the screw rod 1. It should be noted that in some embodiments of the utility model, the screw rod support 101 is fixed on the base through a plurality of fasteners.

[0042] Further, please refer to Figure 1 , the other side of the screw rod 1 is provided with a guide rod 6, the guide rod 6 is opposite to the sliding rail 3, the sliding support 2 is provided with a third sliding block 203, the third sliding block 203 is slidably connected with the guide rod 6. The setting of the guide rod 6 enhances the guiding property of the sliding support 2 during movement, ensures that the sliding support 2 can move stably along the predetermined trajectory, improves the accuracy and stability of the sliding movement. When the sliding support 2 moves under the driving of the driving assembly 5, the third sliding block 203 slides along the guide rod 6, ensuring the stable movement of the sliding support. At the same time, the sliding connection of the guide rod 6 and the third sliding block 203 provides additional support for the sliding support 2, which helps to disperse the load and improve the carrying capacity of the entire sliding movement mechanism.

[0043] Please refer to Figure 4 In the mechanism, a base 7 is further included, the base 7 is formed with a containing cavity 701, the screw rod 1, the sliding support 2, the driving assembly 5 and the guide rod 6 are all arranged in the containing cavity 701. The base 7 enhances the stability of the entire mechanism, so that the sliding movement is more stable and reliable. The containing cavity 701 provides additional protection for the internal components. Integrating all components in the base 7 can also make the entire mechanism look more clean and beautiful, which is conducive to improving the overall image and user experience of the product.

[0044] Further, a load mounting bracket 8 is further included, the load mounting bracket 8 includes a mounting part 801 and a load part 802, the mounting part 801 is connected with the sliding support 2, and the load part 802 extends out of the containing cavity 701. The mounting part 801 enables the load mounting bracket 8 to be stably connected with the sliding support 2, and the load part 802 serves as the part of the load mounting bracket 8 extending out of the containing cavity 701 and is used for connecting external loads.
