Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a steel strip dustproof slide rail. Background Technology

[0002] The sliding mechanism of a car seat requires a long sliding rail. Traditional long sliding rail mechanisms typically have a gap, wide or narrow, in the middle. During use, debris, sand, and other foreign objects may slide into the long sliding rail through this gap, causing malfunctions. Furthermore, some passengers find this gap unsightly and wish to eliminate it. Therefore, there is a need in the market for a dustproof sliding rail that can eliminate this gap.

[0003] To address the dustproof and aesthetic issues inherent in traditional long slide rail mechanisms, several dustproof structural technologies have emerged in the market. Among them, patent application number CN202120780538.4 discloses a dustproof structure for automotive seat slide rails, which improves the problem of exposed slots in the lower slide rails to some extent. This patented dustproof structure mainly includes a housing installed at the end of the lower slide rail, with a hollow interior forming an accommodating space. A through hole is opened in the housing near the slot. A rotating shaft is rotatably mounted on the housing and partially located within the accommodating space. A shielding strip is coiled around the rotating shaft and located within the accommodating space, with its end extending outward from the through hole and fixedly connected to the upper slide rail. Moving along the lower slide rail via the upper slide rail pulls the shielding strip outward to cover the slot. Simultaneously, a resilient body, driven and connected to the rotating shaft, is provided to apply restoring torque to the rotating shaft, causing it to rotate and rewind the shielding strip. However, this structure still has significant shortcomings in practical applications. Its structural design is relatively complex, involving the assembly and coordination of multiple components, including the housing, rotating shaft, shielding strip, and rebound body. This not only increases the difficulty and cost of manufacturing but also makes subsequent maintenance and repair more troublesome. More importantly, the shielding strip used in this structure is made of relatively soft material. During deployment, gaps easily form between the sides of the shielding strip and the sliding rail. Due to vibrations and airflow changes during vehicle movement, dust and other foreign objects can easily drift into the sliding rail through these gaps. This makes the dustproof structure unable to completely and effectively prevent foreign objects from entering the sliding rail, still posing a risk to the sliding safety of the rail and failing to fundamentally solve the dustproof problem of traditional long sliding rail mechanisms. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention aims to provide a steel strip dustproof slide rail to solve the problem of poor shielding effect of traditional dustproof slide rails.

[0005] To achieve the above objectives, this utility model proposes a steel strip dustproof slide rail, including an upper slide rail and a lower slide rail. The lower slide rail is a groove-shaped structure with an open top, and base members are fixedly installed at both ends. The upper slide rail is arranged inside the lower slide rail and is slidably connected to it. It also includes steel strips arranged on the front and rear sides of the upper slide rail. Each steel strip includes a steel coil and a rotating shaft. The rotating shaft is hinged to the corresponding base member. The steel coil is an elastic element that can be rolled into a ring shape in its natural state. The inner end of the steel coil is fixed to the rotating shaft, and the outer end of the steel coil is fixed to the upper slide rail. On both sides of the top opening of the lower slide rail, there is a transverse groove that extends in the front-rear direction. When the upper slide rail slides back and forth relative to the lower slide rail, it can drive the steel coil behind it to unfold. After the steel coil unfolds, its two sides can be inserted into the transverse grooves on both sides to cover the top opening of the lower slide rail. At the same time, the steel coil located in front of the upper slide rail can automatically rewind due to its own elasticity.

[0006] In the above solution: both ends of the upper slide rail are fixedly connected with connectors, and the outer ends of the two steel coils are respectively fixedly connected to the corresponding connectors. When it is necessary to replace or repair the steel coils, the connectors can be quickly disassembled and the steel coils can be removed, greatly saving installation and maintenance time and improving work efficiency. Specifically, both ends of the upper slide rail are integrally provided with a front protrusion feature, and the connectors are snapped onto the front protrusion features on the corresponding sides.

[0007] The above solution also includes an upper trim strip, which is divided into left and right parts. Both parts of the upper trim strip are fixed to the top surface of the lower slide rail by a snap-fit ​​structure. Each part of the upper trim strip can completely cover the corresponding side of the top of the lower slide rail, effectively improving the overall aesthetics of the slide rail, making the car interior more harmonious and beautiful, and meeting the needs of passengers for high-quality car interiors.

[0008] In the above scheme, the snap-fit ​​structure consists of mutually matching Ω-shaped grooves and Ω-shaped protrusions. This snap-fit ​​structure is ingeniously designed, and the installation and disassembly process is extremely simple. Simply align the Ω-shaped protrusions with the Ω-shaped grooves and apply gentle pressure to complete the snap-fit; during disassembly, only an appropriate reverse force needs to be applied to easily separate them.

[0009] In the above solution: a decorative cover is fastened to the top of the base component, which helps to improve the aesthetics and safety of the slide rail.

[0010] In the above solution: the upper slide rail and the lower slide rail are connected by a screw drive mechanism to achieve a front-to-back sliding connection. The screw drive mechanism has the advantages of high transmission accuracy and smooth movement, which can ensure that the upper slide rail slides stably and accurately in the lower slide rail, thereby improving the comfort and reliability of the seat sliding adjustment.

[0011] In the above scheme: the steel coil is a constant force coil spring, which can be wound into a ring shape under natural conditions, and has reliable elasticity and long service life.

[0012] The beneficial effects of this utility model are:

[0013] 1. By installing steel strips on both sides of the upper slide rail, when the upper slide rail slides, the steel strips unfold and insert into the transverse grooves on both sides of the top opening of the lower slide rail, effectively covering the top opening of the lower slide rail. This completely eliminates the gap in the middle of traditional long slide rails, preventing dust, debris, sand, and other foreign objects from entering the slide rail, ensuring the sliding safety of the slide rail, and extending its service life. 2. The transverse grooves also serve a guiding function, accurately guiding the trajectory of the steel coil during movement, thereby effectively reducing the probability of the steel coil jamming due to movement deviation or obstruction. 3. Compared with existing technologies, this utility model has a simpler structure, mainly composed of an upper slide rail, a lower slide rail, steel strips, and a base component. This reduces unnecessary complex structures, lowers manufacturing difficulty and cost. Furthermore, the connection method between the components is simple and reliable, facilitating installation and maintenance, and allowing for quick repair and replacement in case of malfunction.

[0019] like Figure 1 As shown in Figure 5, a steel strip dustproof slide rail mainly consists of an upper slide rail 5, a lower slide rail 6, and steel strips 2 arranged on the front and rear sides of the upper slide rail 5.

[0020] The lower slide rail 6 is a groove-shaped structure with an open top, and base parts 1 are fixedly installed at both ends. The upper slide rail 5 is arranged inside the lower slide rail 6 and is slidably connected to it.

[0021] Each side of the steel strip 2 includes a steel coil 21 and a rotating shaft 22. The rotating shaft 22 is hinged to the corresponding base member 1. The steel coil 21 is an elastic member that can be wound into a ring shape in its natural state. The inner end of the steel coil 21 is fixed to the rotating shaft 22, and the outer end of the steel coil 21 is fixed to the upper slide rail 5.

[0022] On both sides of the opening at the top of the lower slide rail 6, there is a horizontal groove 8, which extends in the front-back direction.

[0023] When the upper slide rail 5 slides back and forth relative to the lower slide rail 6, it can cause the steel coil 21 behind it to unfold. After the steel coil 21 unfolds, its two sides can be inserted into the horizontal grooves 8 on both sides respectively, so as to cover the opening at the top of the lower slide rail 6. At the same time, the steel coil 21 located in front of the upper slide rail 5 can automatically rewind by its own elasticity.

[0024] Ideally, both ends of the upper slide rail 5 are secured with connectors 4, and the outer ends of the two steel coils 21 are respectively fixedly connected to the corresponding connectors 4. When it is necessary to replace or repair the steel coils 21, the connectors 4 can be quickly disassembled and the steel coils 21 can be removed, greatly saving installation and maintenance time and improving work efficiency. Specifically, both ends of the upper slide rail 5 are integrally provided with front protrusions 51, and the connectors 4 are secured to the corresponding front protrusions 51.

[0025] Ideally, it should also include an upper trim strip 3, which is divided into left and right parts. Both parts of the upper trim strip 3 are fixed to the top surface of the lower slide rail by a snap-fit ​​structure. Each part of the upper trim strip 3 can completely cover the corresponding side of the top of the lower slide rail 6, effectively improving the overall aesthetics of the slide rail, making the car interior more harmonious and beautiful, and meeting the passengers' demand for high-quality car interiors.

[0026] Ideally, the snap-fit ​​structure consists of mutually matching Ω-grooves 31 and Ω-shaped protrusions 32. This snap-fit ​​structure is ingeniously designed, and the installation and disassembly process is extremely simple. Simply align the Ω-shaped protrusions 32 with the Ω-grooves 31 and apply light pressure to complete the snap-fit; during disassembly, only an appropriate reverse force needs to be applied to easily separate them.

[0027] Ideally, a decorative cover 7 should be fastened to the top of the base component 1 to improve the aesthetics and safety of the slide rail.

[0028] Ideally, a screw drive mechanism should be used to achieve a front-to-back sliding connection between the upper slide rail 5 and the lower slide rail 6. The screw drive mechanism has the advantages of high transmission accuracy and smooth movement, which can ensure that the upper slide rail slides stably and accurately in the lower slide rail, thereby improving the comfort and reliability of the seat sliding adjustment.

[0029] Ideally, the steel coil 21 should be a constant force coil spring, which can be wound into a ring shape under natural conditions, with reliable elasticity and a long service life.
