TECHNICAL FIELD
[0001] The utility model relates to the technical field of automobile seat parts, and particularly relates to a reinforced slide rail of an automobile seat. BACKGROUND
[0002] The slide rail is an important mechanical component on the seat, and the common slide rail is mainly installed below the seat and is used as a mechanism for adjusting the front and back positions of the seat. The automobile seat slide rail comprises an upper slide rail, a lower slide rail, a transmission mechanism and a rolling element. The upper slide rail is connected to a seat framework, and the lower slide rail is connected to a vehicle floor. The transmission mechanism mainly comprises a gear box and a lead screw. The gear box is suspendedly fixed to the upper slide rail through a U-shaped support. The lead screw is supported and fixed to the lower slide rail by a support seat. Firstly, power is transmitted to the lead screw through an output shaft. The transmission mechanism in the gear box can be engaged with the lead screw, and then axial displacement along the lead screw can be achieved, so as to drive the upper slide rail to displace relative to the lower slide rail.
[0003] With the improvement of the quality requirements of consumers on automobile interiors, the automobile seat is provided with functions such as the zero-gravity state and SBA, which puts forward higher requirements on the front and back strength of the slide rail. The existing ordinary slide rail gear box is unstable in installation through the U-shaped support, and the support of the lead screw fixing mode is insufficient, which cannot meet the strength requirements.
[0004] Therefore, it is urgent to develop a reinforced slide rail to meet the higher front and back requirements of the seat. CONTENT OF THE UTILITY MODEL

The two vertical plates are both provided with a protruding part extending outward. The two side walls of the mounting groove are provided with support holes. The protruding parts are supported in the support holes. The two ends of the lead screw are fixedly installed at the front and back ends of the sliding inner cavity through support seats. The support seat has a threaded hole matched with the lead screw. The end of the lead screw is screwed in the threaded hole.
[0008] A gear box is fixedly installed on the mounting bracket and is in threaded transmission cooperation with the lead screw.
[0009] With the above structure, the convex part and the supporting hole can improve the stability of the gear box installation, the lead screw is connected to the support seat by screwing through its own thread, which has higher strength and can meet the strength requirements of existing multifunctional car seats.

With the above structure, the sliding of the upper slide rail is facilitated, and the clearance avoids the convex part.
[0015] As a preferred, a rolling assembly is provided between the outer side of the matching part and the sliding inner cavity. With the above structure, the sliding rail moves more smoothly and stably.
[0016] As a preferred, the middle position of the matching part is outwardly protruding in the length direction, the rolling assembly includes rolling balls on the upper and lower sides of the protruding structure and a connecting frame connecting the upper and lower rolling balls, the rolling balls are in rolling cooperation with the matching part and the sliding inner cavity, and the sliding inner cavity has outwardly protruding limiting parts at both ends of the inner wall, which are used to limit the rolling balls. With the above structure, the rolling assembly is installed by using the protruding structure, which is simple and compact in structure, and the sliding rail moves smoothly.

[0032] The present invention will be further described below with reference to the embodiments and accompanying drawings.
[0033] like Figure 1 As shown, a car seat reinforcement slide rail includes an upper slide rail 2 and a lower slide rail 1. The lower slide rail 1 is used to fix to the car floor, and the upper slide rail 2 is used to connect to the car seat. The lower slide rail 1 has a rectangular structure and a sliding inner cavity 1a extending along its length. The upper end of the sliding inner cavity 1a has a clearance opening 1b. The upper slide rail 2 is slidably installed in the sliding inner cavity 1a. Figure 2As shown, the lower end of the upper slide rail 2 has a mounting groove 2a extending along its length, and the upper middle position of the mounting groove 2a has a mounting opening 2c. A mounting bracket 3 is installed inside the mounting groove 2a at the position corresponding to the mounting opening 2c. Figure 6 As shown, the mounting bracket 3 includes a horizontal support plate 3a and two vertical plates 3b extending upward from both ends of the horizontal support plate 3a. Both vertical plates 3b have outwardly extending stepped protrusions 3c on both sides, such as... Figure 3 As shown, support holes 2b are provided on both sides of the mounting groove 2a, and the protrusion 3c is supported in the support holes 2b.
[0034] like Figure 8 As shown, a lead screw 4 is also installed inside the sliding inner cavity 1a. Both ends of the lead screw 4 are fixedly installed at the front and rear ends of the sliding inner cavity 1a via support seats 8. The support seats 8 have threaded holes that match the lead screw 4. The lead screw 4 uses its own threads to engage with the threaded holes, and its end is screwed into the threaded holes. Figure 7 As shown, the upper end of the support base 8 has a rectangular structure, and the lower end is widened and connected to the bottom of the lower slide rail 1 by two threaded fasteners 9. Figure 4 As shown, a gearbox 5 is fixedly mounted on the mounting bracket 3, and the gearbox 5 is threadedly connected to the lead screw 4.
[0035] like Figure 4 and Figure 5 As shown, in this embodiment, the upper end of the upright plate 3b of the mounting bracket 3 is provided with outwardly folded lugs 3d. The lugs 3d are fixed to the top of the mounting groove 2a by bolts, thereby fixing the mounting bracket 3. The upper end of the gearbox 5 is covered with a rubber sleeve 6 to protect the gearbox 5. The upper middle part of the rubber sleeve 6 has an arc-shaped protrusion structure, which can guide debris to both sides and reduce the probability of debris falling into the gearbox.
[0036] like Figure 7 and Figure 9As shown, the upper slide rail 2 has a rectangular structure in the middle of its width direction, with a clearance opening 1b extending from its upper end. The bottom of the lower rectangular structure has mating parts 2d extending to both sides. A clearance gap 2e is provided between the mating parts 2d and the rectangular structure to allow clearance from the protrusion 3c. The mating parts 2d protrude outwards along their length from their middle position. Rolling components 7 are provided between the mating parts 2d on both sides and the sliding cavity 1a. The rolling components 7 include three sets of rolling balls 71 on the upper and lower sides of the protruding structure and a connecting frame 72 connecting the three sets of rolling balls 71. Among the three sets of rolling balls 71, the rolling ball 71 located on the lower side of the protruding structure is larger than the upper rolling ball 71, providing better support. The rolling balls 71 have a rolling fit with both the mating parts 2d and the sliding cavity 1a. The protruding structure naturally restricts the upper and lower rolling balls 71, preventing them from sliding up and down. Two sets of rolling components 7 are symmetrically arranged on both sides of the mounting bracket 3, and the inner wall end of the sliding inner cavity 1a and the position near the mounting bracket 3 are provided with outwardly protruding limiting parts 2f. The limiting parts 2f are used to limit the rolling ball 71 and prevent the rolling ball 71 from rolling out of the slide rail or colliding with the mounting bracket 3.
[0037] like Figure 7 and Figure 8 As shown, when the lead screw 4 is driven to rotate by input power, the transmission mechanism inside the gearbox 5 can mesh with the lead screw 4. The gearbox 5 is fixed to the upper slide rail 2, thereby allowing the upper slide rail 2 to move axially along the lead screw 4. The lead screw 4 is fixed to the lower slide rail 1, thus realizing the displacement of the upper slide rail 2 relative to the lower slide rail 1. During this process, the rolling component 7 can provide support for the upper slide rail 2 and move with the upper slide rail 2, ensuring smooth movement of the upper slide rail 2. In addition to being fixed to the upper slide rail 2 at its upper end, the mounting bracket 3 also has a protrusion 3c that cooperates with the support hole 2b, making the installation of the gearbox 5 on the mounting bracket 3 more stable. In addition, the two ends of the lead screw 4 are screwed to the support seat 8 using their own threads, and the support seat 8 is then connected to the lower slide rail 1 by two threaded fasteners 9. This connection method can greatly improve the strength of the slide rail, making it meet diverse usage needs.
[0038] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
