Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to an adjustable slide for a seat frame. Background Technology

[0002] Currently, car seats are basically divided into two types: genuine leather seats and cloth seats. There are also child seats, traffic seats, etc. Leather classification and characteristics: Cowhide, also known as Grade A leather, is the most common material used in all genuine leather car seats. It has a delicate surface, a soft feel, almost no visible pores, and a strong yet very resilient texture, resulting in extremely beautiful seats. Current seat adjustments typically use screws, but these screws are easily exposed to dust, affecting transmission.

[0003] For example, a Chinese patent document discloses an adjustable slide for a seat frame (publication number: CN215904356U). Although this patent has a slider between the mounting plate and the slide groove, and a ball, a groove, a guide pulley and a guide groove between the slider and the slide seat, it can avoid friction between the slider and the slide seat during the movement, prevent wear, and improve the smoothness of movement.

[0004] However, the lead screw used for seat adjustment is installed in an open groove. During daily use, dust brought in by people, dust entering through open windows, sand and gravel from shoes, and even snack residue can easily enter the groove and adhere firmly to the surface of the lead screw. Initially, a small amount of dust makes the lead screw slightly rough, resulting in a stiff adjustment feel and slower speed. However, over time, dust and impurities accumulate, filling the gaps in the thread, increasing friction, consuming more adjustment power, and drastically reducing transmission accuracy. This often leads to situations where the seat cannot be adjusted properly or gets stuck. Furthermore, the overall support force of the seat acts directly on the lead screw, which can easily lead to accelerated wear of the lead screw and reduce its service life. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the fact that lead screws exposed to the external environment are prone to dust accumulation, and the direct force of the seat support acting on the lead screw can easily lead to accelerated wear.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable slide for a seat frame includes a slide body, the upper end of which has symmetrically distributed slots, the interior of which has an installation cavity, the inner walls of which have symmetrically distributed travel grooves, the inner bottom wall of which has a sliding groove, and the interior of which has a dustproof mechanism, which includes a travel block, the exterior of which is slidably connected to the inner wall of the travel groove. The front and back of the travel block are fixedly connected with symmetrically distributed folding curtains. One end of each of the two folding curtains is fixedly connected to the front inner wall and the rear inner wall of the travel groove, respectively. The lower end of each folding curtain is fixedly connected with a linearly arrayed sliding rod. The lower end of the sliding rod is slidably connected to the inner wall of the slide groove. A convenient disassembly mechanism is provided on the top of the slide body.

[0007] Preferably, a servo motor is fixedly installed on the rear inner wall of the mounting cavity, and a lead screw is fixedly installed on the output shaft of the servo motor through a coupling. One end of the lead screw is rotatably connected to the front inner wall of the mounting cavity through a bearing.

[0008] Preferably, the lead screw is externally threaded with a threaded block, and the inner walls of both ends of the threaded block are movably fitted with symmetrically distributed limiting rods, and the two ends of the limiting rods are respectively fixedly connected to the front inner wall and the rear inner wall of the mounting cavity.

[0009] Preferably, one end of the threaded block is fixedly connected to one end of the stroke block, and the other end of the stroke block extends into the cavity.

[0010] Preferably, the convenient disassembly mechanism includes guide rails, the lower ends of the two guide rails are symmetrically distributed and fixedly connected to the upper end of the slide body, a movable sleeve is slidably sleeved on the outside of the guide rails, an mounting plate is fixedly connected to the upper end of the movable sleeve, and a connecting block is fixedly connected to one side of the movable sleeve.

[0011] Preferably, a rectangular guide rod is fixedly connected to the lower end of the connecting block, a rectangular positioning block is fixedly connected to the lower end of the rectangular guide rod, a movable connecting cover is slidably sleeved on the outside of the rectangular positioning block, and a retraction spring is fixedly connected to the inner top wall of the movable connecting cover.

[0012] Preferably, one end of the retraction spring is fixedly connected to the upper end of the rectangular positioning block, a fixing block is movably inserted into the lower inner wall of the movable connecting cover, and the lower end of the fixing block is fixedly connected to the upper part of the other end of the travel block.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this utility model, the combined use of a dustproof mechanism and a convenient disassembly mechanism allows the folding curtain to move synchronously when the travel block moves, and the slide rod to slide in the slide groove. This effectively prevents dust from entering the travel groove and the mounting cavity, protecting internal components such as the lead screw and threaded block, and extending the service life of the slide. Furthermore, by pulling the movable connecting cover to overcome the tension of the compression spring, it can be separated from or engaged with the fixed block, facilitating the disassembly and installation of the mounting plate and related components, and promoting later maintenance and replacement.

[0020] Example

[0021] like Figure 1-6 As shown, this utility model provides a technical solution: an adjustable slide for a seat frame, including a slide body 1, a dustproof mechanism and a convenient disassembly mechanism. The slide body 1 serves as a basic support structure and has an internal mounting cavity 3 for accommodating adjustment components. The dustproof mechanism prevents dust from entering the interior and affecting the adjustment function. The convenient disassembly mechanism facilitates the disassembly and installation of components such as the mounting plate 72, making it convenient for later maintenance.

[0022] The upper end of the slide body 1 is provided with symmetrically distributed slots 2 through machining, and the interior is provided with an installation cavity 3. The inner walls on both sides of the installation cavity 3 are provided with symmetrically distributed stroke slots 4 through machining. The inner bottom wall of the stroke slot 4 is provided with a sliding groove 5. The outer side of the stroke block 6 is connected to the inner wall of the stroke slot 4 through a precise sliding sleeve structure to ensure that the stroke block 6 can slide smoothly in the stroke slot 4.

[0023] The front and back of the travel block 6 are fixedly connected with symmetrically distributed folding curtains 61 by welding or bonding. One end of each folding curtain 61 is fixedly connected to the front inner wall and the rear inner wall of the travel groove 4 by welding or bonding. The lower end of the folding curtain 61 is fixedly connected with linearly distributed sliding rods 62 by welding or bonding. The lower end of the sliding rods 62 is connected to the inner wall of the slide groove 5 by a precise sliding sleeve structure, so that the folding curtains 61 can effectively block the opening of the travel groove 4 when the travel block 6 moves.

[0024] A servo motor 63 is fixedly installed on the rear inner wall of the mounting cavity 3 by means of screws or other means. The output shaft of the servo motor 63 is fixedly connected to the lead screw 64 by a coupling. One end of the lead screw 64 is rotatably connected to the front inner wall of the mounting cavity 3 by a bearing. The outside of the lead screw 64 is connected to the threaded block 65 by a precision thread. The inner walls of both ends of the threaded block 65 are connected to the symmetrically distributed limit rods 66 by a movable sleeve structure. The two ends of the limit rods 66 are fixedly connected to the front inner wall and the rear inner wall of the mounting cavity 3 by means of welding or screws, respectively.

[0025] One end of the threaded block 65 is fixedly connected to one end of the stroke block 6 by welding or bolting, and the other end of the stroke block 6 extends into the cavity 2 to realize power transmission and position adjustment.

[0026] The lower ends of the two guide rails 7 are symmetrically distributed and are fixedly connected to the upper end of the slide body 1 by welding or screw fixing. The exterior of the guide rails 7 is connected to the movable sleeve 71 by a precision sliding sleeve structure. The guide rails 7 and the movable sleeve 71 work together to avoid stress on the lead screw 64 and improve service life. The upper end of the movable sleeve 71 is fixedly connected to the mounting plate 72 by welding or bolting. A connecting block 73 is fixedly connected to one side of the movable sleeve 71 by welding or bolting.

[0027] A rectangular guide rod 74 is fixedly connected to the lower end of the connecting block 73 by welding or bolting. A rectangular positioning block 75 is fixedly connected to the lower end of the rectangular guide rod 74 by welding or bolting. The outside of the rectangular positioning block 75 is connected to the movable connecting cover 76 by a precise sliding sleeve structure. A retraction spring 77 is fixedly connected to the inner top wall of the movable connecting cover 76 by welding or bonding.

[0028] One end of the retraction spring 77 is fixedly connected to the upper end of the rectangular positioning block 75 by welding or bonding. The lower inner wall of the movable connecting cover 76 is connected to the fixed block 78 by a precise movable plug-in structure. The lower end of the fixed block 78 is fixedly connected to the upper part of the other end of the stroke block 6 by welding or bolting, so as to facilitate the disassembly and installation of components such as the mounting plate 72.

[0029] The working process of this utility model: Step 1: When the seat frame position needs to be adjusted, the servo motor 63 is turned on. The output shaft of the servo motor 63 drives the lead screw 64 to rotate. Since the lead screw 64 is threadedly engaged with the threaded block 65, and the threaded block 65 is restricted by the limiting rod 66 to move only along the axial direction of the lead screw 64, the threaded block 65 will move linearly along the lead screw 64. When the threaded block 65 moves, it drives the stroke block 6 to move in the stroke groove 4, thereby realizing the position adjustment of the seat frame. During the movement of the stroke block 6, the folding curtains 61 on the front and back of the stroke block 6 unfold or retract with the movement of the stroke block 6. At the same time, the slide rod 62 at the lower end of the folding curtain 61 slides in the slide groove 5, always blocking the opening of the stroke groove 4, effectively preventing dust from entering the stroke groove 4 and the mounting cavity 3, protecting the internal components such as the lead screw 64 and the threaded block 65, and extending the service life of the slide. Step 2: When maintenance or replacement of parts is required for the slide block, disassembly is performed. Pull the movable connecting cover 76 to move it upward against the elastic force of the contraction spring 77, separating the movable connecting cover 76 from the fixed block 78. Then move the mounting plate 72, which drives the movable sleeve 71 to slide on the guide rail 7 to one end and detach. During installation, first align the movable sleeve 71 with the guide rail 7 and slide it to the designated position. Then pull the movable connecting cover 76 upward against the elastic force of the contraction spring 77 and align it with the fixed block 78. After releasing, the movable connecting cover 76 automatically engages with the fixed block 78 under the action of the contraction spring 77, completing the installation.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
