Description

Technical Field

[0001] This utility model relates to the field of automotive seat slide rail technology, and in particular to a slide rail shielding strip conveying mechanism. Background Technology

[0002] With the upgrading of family travel needs, MPV models have become a new market favorite due to their spaciousness and flexible layout. The application rate of electric sliding rails, a core component of their seat adjustment function, has also increased accordingly. To prevent dust, debris, and other foreign objects from entering the sliding rails and causing jamming or wear, and to ensure the long-term stable operation and maintain a clean appearance, the industry generally installs a shielding strip at the lower rail opening. Among the current mainstream shielding strip types, open-type shielding strips have obvious gaps due to structural design flaws, failing to achieve a complete seal, and the risk of foreign object intrusion remains. While zipper-type and roll-type shielding strips can improve sealing, they are prone to noise due to friction during operation, and their complex mechanical structure leads to a higher failure rate and significantly increased maintenance costs.

[0003] Among various types of sunshades, full-coverage sunshades offer superior sealing and durability, making them the preferred choice for most high-end MPVs. However, existing structures still have drawbacks: their arrangement path within the upper rail bracket must bypass the longitudinally mounted motor. To prevent interference between the sunshade and the motor, sufficient clearance must be provided. This design, combined with the thickness of the sunshade itself, the installation structure, and the motor height, directly increases the Z-axis height of the slide rail. This not only increases the space occupied under the seat but also directly affects the setting of the seat's H-point (i.e., the seat's reference point), resulting in a higher overall seat position. This compresses legroom for passengers and reduces center of gravity stability during seating, clearly conflicting with the comfortable driving experience sought after by MPVs. Summary of the Invention

[0004] The purpose of this invention is to provide a slide rail shielding strip conveying mechanism to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A sliding rail shielding strip conveying mechanism includes: The lower rail has a groove; The upper rail bracket has its bottom slidably connected to the slide groove, and its top is used to install the car seat. A longitudinally mounted motor, installed inside the upper rail bracket, is used to drive the upper rail bracket to move along the slide groove; and The shielding strip has its first end fixed to the first end of the lower rail, and its second end passing through the inside of the upper rail bracket and then fixed to the second end of the lower rail. The portion of the shielding strip outside the upper rail bracket horizontally covers the slide groove, while the portion of the shielding strip inside the upper rail bracket deviates from the horizontal direction through a torsion assembly and wraps around one side of the longitudinally mounted motor.

[0006] In one possible implementation, the upper rail support is provided with pressing components at both ends, the pressing components being located above the shielding strip and used to horizontally cover the sliding groove with the shielding strip located outside the upper rail support.

[0007] In one possible implementation, the pressing assembly includes a first pressing roller and a second pressing roller that are rotatably connected to both ends of the inner side of the upper rail bracket in a horizontal direction.

[0008] In one possible implementation, a guide component is further provided between the torsion component and the pressing component. The guide component is located below the shielding strip and is used to support and guide the shielding strip between the pressing component and the torsion component.

[0009] In one possible implementation, the guiding assembly includes a first guide roller and a second guide roller that are rotatably connected in the horizontal direction within the upper rail bracket.

[0010] In one possible implementation, the torsion assembly includes at least one torsion roller rotatably connected to one side of the interior of the upper rail bracket in a vertical direction, the torsion roller deflecting the shielding strip off the horizontal direction and around one side of the longitudinally mounted motor.

[0011] In one possible implementation, there are two torsion rollers, which are spaced apart on one side of the longitudinally mounted motor.

[0012] In one possible implementation, the portion of the shielding strip outside the upper rail bracket engages with the slide groove.

[0013] The beneficial effects of the technical solution provided by this utility model include at least the following: The sliding rail shielding strip conveying mechanism provided by this technical solution includes a lower rail with a groove; an upper rail bracket, the bottom of which is slidably connected to the groove, and the top of which is used to install a car seat; a longitudinal motor installed inside the upper rail bracket to drive the upper rail bracket to move along the groove; and a shielding strip, the first end of which is fixed to the first end of the lower rail, and the second end of which passes through the inside of the upper rail bracket and is fixed to the second end of the lower rail. The portion of the shielding strip outside the upper rail bracket horizontally covers the groove, while the portion inside the upper rail bracket is deflected from the horizontal direction by a torsion assembly and loops around one side of the longitudinal motor. In this configuration, interference with the longitudinal motor can be completely avoided by the looping of the shielding strip, and the Z-axis height of the sliding rail can be significantly reduced, allowing the seat's H-point to be reasonably lowered. Simultaneously, the lateral space of the sliding rail is fully utilized, effectively improving the utilization rate of the vehicle interior space and passenger comfort while ensuring the normal arrangement of the longitudinal motor.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Figure 1 This diagram illustrates the structure of a slide rail shielding strip conveying mechanism provided in an exemplary embodiment of the present invention. Figure 2 This diagram illustrates the structure of the slide rail shielding strip conveying mechanism after concealing one side of the upper rail support, according to an exemplary embodiment of the present invention. Figure 3 This illustration shows a schematic diagram of the torsion of a sliding rail shielding strip conveying mechanism according to an exemplary embodiment of the present invention. The sliding rail shielding strip conveying mechanism includes: a lower rail 1 having a groove 11; an upper rail bracket 2, the bottom of which is slidably connected to the groove 11, and the top of which is used to mount a car seat; a longitudinal motor 3, which is mounted on the inner side of the upper rail bracket 2 and is used to drive the upper rail bracket 2 to move along the groove 11; and a shielding strip 4, the first end of which is fixed to the first end of the lower rail 1, and the second end of which passes through the inner side of the upper rail bracket 2 and is fixed to the second end of the lower rail 1; wherein, the portion of the shielding strip 4 outside the upper rail bracket 2 horizontally covers the groove 11, and the portion of the shielding strip 4 inside the upper rail bracket 2 is deviated from the horizontal direction by a torsion assembly 5 and wraps around one side of the longitudinal motor 3.

[0023] In this embodiment, the groove 11 of the lower rail 1 provides a sliding track for the upper rail bracket 2. The bottom of the upper rail bracket 2 cooperates with the groove 11 to realize the translational adjustment of the seat. The top of the upper rail bracket 2 supports the seat to ensure structural stability. The longitudinal motor 3 is installed inside the upper rail bracket 2 and drives the upper rail bracket 2 to move along the groove 11 to ensure efficient power transmission. The part of the shielding strip 4 outside the upper rail bracket 2 horizontally covers the groove 11 to form a sealing barrier to block foreign objects. The part of the shielding strip 4 inside the upper rail bracket 2 is deflected by the torsion component 5 and cleverly bypasses the longitudinal motor 3. This torsion structure not only avoids the motion interference between the shielding strip 4 and the longitudinal motor 3, but also breaks the layout limitation that the traditional shielding strip 4 needs to cross over the longitudinal motor 3. Instead, it uses the lateral space to avoid the obstacle. By bypassing the longitudinal crossing, the mechanism can significantly reduce the space occupation in the Z direction while ensuring the shielding function and normal operation of the motor. Finally, it can achieve the compression of the rail height and the optimization of the seat H point, taking into account the sealing performance, power performance and space utilization.

[0024] As a supplementary explanation, the longitudinal motor 3 drives the upper rail bracket 2 to move along the slide groove 11 through a screw and nut mechanism or a gear and rack mechanism. This application does not limit the driving method of the longitudinal motor 3.

[0025] For details, please refer to Figure 2 and Figure 3 The upper rail bracket 2 has pressing components 6 at both ends. The pressing components 6 are located above the shielding strip 4 and are used to horizontally cover the slide groove 11 with the shielding strip 4 located outside the upper rail bracket 2. In one example, the pressing components 6 include a first pressing roller 61 and a second pressing roller 62 that are rotatably connected to the inner ends of the upper rail bracket 2 in a horizontal direction.

[0026] In this embodiment, the first pressing roller 61 and the second pressing roller 62, which are set above the shielding strip 4, press the shielding strip 4 outside the upper rail bracket 2 tightly onto the surface of the slide groove 11 by means of the pressure of the rollers, so as to ensure that the shielding strip always maintains a horizontal covering state.

[0027] For more details, see [link to relevant documentation]. Figure 2 and Figure 3 A guide component 7 is also provided between the torsion component 5 and the pressing component 6. The guide component 7 is located below the shielding strip 4 and is used to support and guide the shielding strip 4 between the pressing component 6 and the torsion component 5. In one example, the guide component 7 includes a first guide roller 71 and a second guide roller 72 that are rotatably connected in the upper rail bracket 2 in the horizontal direction.

[0028] In this embodiment, when the shielding strip 4 transitions from the outer horizontal section to the inner torsional section, the first guide roller 71 and the second guide roller 72 provide stable support, preventing the shielding strip 4 from sagging and deforming due to its own weight or tension. They also reduce contact friction and wear through rotational characteristics. The structure with the pressing assembly 6 on top and the guide assembly 7 below ensures the stability of the shielding strip 4 in the transition area, ensuring it can both tightly cover the groove and smoothly complete its torsional rotation, thus improving the overall operational reliability of the mechanism.

[0029] Further, see Figure 2 and Figure 3 The torsion assembly 5 includes at least one torsion roller 51 rotatably connected to one side of the upper rail bracket 2 in a vertical direction. The torsion roller 51 deflects the shielding strip 4 away from the horizontal direction and makes it circumferentially move around one side of the longitudinally mounted motor 3. Preferably, there are two torsion rollers 51, which are spaced apart on one side of the longitudinally mounted motor 3.

[0030] In this embodiment, the direction of the shielding strip 4 is changed by the torsion roller 51 to avoid the longitudinally mounted motor 3. The torsion roller 51 guides the shielding strip 4, causing it to deviate from a horizontal position and circumnavigate around the side of the longitudinally mounted motor 3. Preferably, two spaced torsion rollers 51 are provided, which can guide the shielding strip 4 step by step to make the turning of the shielding strip 4 smoother and avoid deformation or jamming caused by a single large torsion. This design not only ensures the sealing coverage of the slide groove 11 by the shielding strip 4, but also effectively reduces the Z-axis height of the slide rail by lateral circumduction instead of longitudinal crossing, without affecting the normal operation of the motor.

[0031] In some embodiments, the portion of the shielding strip 4 outside the upper rail bracket 2 is engaged with the slide groove 11.

[0032] In one example, the opening edge of the groove 11 is provided with a groove extending along the length direction, and the bottom edge of the shielding strip 4 is provided with an elastic flange that matches the groove, and the flange is embedded in the groove to form a fastening.

[0033] In another example, the bottom two sides of the shielding strip 4 are provided with grooves extending along the length direction, and the opening edge of the groove 11 is provided with an elastic flange that matches the groove, and the flange is embedded in the groove to form a fastening.

[0034] Next, the working principle of a slide rail shielding strip conveying mechanism involved in the embodiments of this utility model will be explained.

[0035] First, the longitudinal motor starts and transmits power to the upper rail bracket through a screw and nut or a gear and rack mechanism, driving it to slide horizontally along the groove of the lower rail to achieve seat position adjustment; At this time, the shielding strip outside the upper rail bracket is kept horizontally covered by the bottom fastening structure with the slide groove, while the pressing components at both ends of the upper rail bracket apply pressure from above to ensure that the shielding strip fits tightly with the slide groove and prevents foreign objects from entering.

[0036] When the shielding strip enters the upper rail bracket, it is first supported from below by the guide component. Then, the shielding strip contacts the torsion roller of the torsion component. Guided by the vertically rotating roller, it gradually deviates from the horizontal direction and smoothly travels around to the side of the longitudinally placed motor, completing the transition from the outer horizontal section to the inner torsion section.

[0037] In summary, the sliding rail shielding strip conveying mechanism provided by this technical solution includes a lower rail with a groove; an upper rail bracket, the bottom of which is slidably connected to the groove, and the top of which is used to install a car seat; a longitudinal motor installed inside the upper rail bracket to drive the upper rail bracket to move along the groove; and a shielding strip, the first end of which is fixed to the first end of the lower rail, and the second end of which passes through the inner side of the upper rail bracket and is fixed to the second end of the lower rail. The portion of the shielding strip outside the upper rail bracket horizontally covers the groove, while the portion inside the upper rail bracket is deflected from the horizontal direction by a torsion assembly and loops around one side of the longitudinal motor. In this configuration, interference with the longitudinal motor can be completely avoided by the looping of the shielding strip, and the Z-axis height of the sliding rail can be significantly reduced, allowing for a reasonable lowering of the seat's H-point. Simultaneously, the lateral space of the sliding rail is fully utilized, effectively improving the utilization rate of the vehicle's interior space and passenger comfort while ensuring the normal arrangement of the longitudinal motor.

[0038] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
