[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] like Figures 1 to 10 As shown, a sliding seat adjustment device includes a fixed base 1, a first adjustment rod 3, a second adjustment rod 4, an adjustment seat 2, and a spring pull ring 5. Two fixed bases 1 are provided, symmetrically fixed on both sides of the vehicle frame. Each fixed base 1 has a first adjustment groove 11, a second adjustment groove 12, an opening groove 16, a first fixing hole 13, and a second fixing hole 14. The first adjustment groove 11 and the second adjustment groove 12 are located at opposite ends of the fixed base 1, and their structures are identical, allowing for simultaneous adjustment of the seat's front-to-back position and height. The opening groove 16 is located at one end of the fixed base 1 and communicates with the second adjustment groove 12, allowing the second adjustment groove 12 to communicate with the end of the fixed base 1. The first fixing hole 13 and the second fixing hole 14 correspond to the first adjustment groove 11 and the second adjustment groove 12, respectively. The first adjusting rod 3 is installed at one end of the adjusting seat 2, and both ends of the first adjusting rod 3 are movably inserted into the first adjusting groove 11; the second adjusting rod 4 is installed at the other end of the adjusting seat 2, and both ends of the second adjusting rod 4 are movably inserted into the second adjusting groove 12; there are two adjusting seats 2, which are symmetrically fixed on both sides of the bottom of the seat cushion, and both adjusting seats 2 are movably inserted between two fixed seats 1, and respectively movably abut against the two fixed seats 1; there are two spring pull rings 5, which are symmetrically fixed on the adjusting seat 2; when the first adjusting rod 3 and the second adjusting rod 4 are located at one end of the first adjusting groove 11 and the second adjusting groove 12, the spring pull rings 5 ​​are inserted into the first fixing hole 13; when the first adjusting rod 3 and the second adjusting rod 4 are located at the other end of the first adjusting groove 11 and the second adjusting groove 12, the spring pull rings 5 ​​are inserted into the second fixing hole 14.

[0027] When adjusting the seat position, pull the spring ring 5 from the adjustment hole on the frame to separate the spring ring 5 from the fixing hole, and then push the seat to move within the first adjustment groove 11 and the second adjustment groove 12 to adjust the front-to-back position and the height position. When adjusted to the set position, the spring ring 5 is inserted into the corresponding fixing hole. The spring ring 5 and the fixing hole are used to limit the seat position and prevent the seat from sliding freely within the first adjustment groove 11 and the second adjustment groove 12 in a free state, thus locking the position.

[0028] like Figures 1 to 7As shown, the second adjusting rod 4 can slide out of the fixed seat 1 through the opening slot 16, while the first adjusting rod 3 is still located in the first adjusting slot 11. Then, the adjusting seat 2 is rotated upward so that the second adjusting rod 4 is above the fixed seat 1, and then slides towards the first lower positioning slot 113 so that the end of the adjusting seat 2 moves out to the outside of the end of the fixed seat 1. The first adjusting rod 3 can rotate in the first adjusting slot 11, thereby realizing the flipping of the seat cushion and revealing the storage space under the seat cushion.

[0029] The first adjustment groove 11 includes a first upper positioning groove 111 and a first lower positioning groove 113, which are horizontally arranged and have different heights, and a first connecting groove 112 that communicates with the first upper positioning groove 111 and the second lower positioning groove 113 respectively. The second adjustment groove 12 includes a second upper positioning groove 121 and a second lower positioning groove 123, which are horizontally arranged and have different heights, and a second connecting groove 122 that communicates with the second upper positioning groove 121 and the second lower positioning groove 123 respectively. The opening groove 16 communicates with the second upper positioning groove 121. The second upper positioning groove 121 is located at the top of one end of the adjustment seat 2.

[0030] When the first adjusting rod 3 and the second adjusting rod 4 are respectively located in the first lower positioning groove 113 and the second lower positioning groove 123, the spring pull ring 5 is inserted into the first fixing hole 13. At this time, the seat cushion is back and the height is low. When the first adjusting rod 3 and the second adjusting rod 4 are respectively located in the first upper positioning groove 111 and the second upper positioning groove 121, the spring pull ring 5 is inserted into the second fixing hole 14. At this time, the seat cushion is forward and the height is high.

[0031] To improve the strength of the mounting base 1, prevent deformation, and increase its load-bearing capacity, the mounting base 1 has an upper folded edge 181 and a lower folded edge 182 at its top and bottom, respectively. The lower folded edge 182 has a lower connecting hole 183, which is connected to the vehicle frame by screws. The mounting base 1 is formed by stamping from sample sheet metal, resulting in low processing costs and a U-shaped structure with high strength.

[0032] To improve the strength of the end of the fixed base 1 and reduce the impact of the opening slot 16 on the strength, a reinforcing plate 17 is welded to the end of the fixed base 1. The reinforcing plate 17 has a clearance slot 171 that communicates with the opening slot 16, which facilitates the sliding out of the second adjusting rod 4. The reinforcing plate 17 is also welded together with the upper folded edge 181 and the lower folded edge 182.

[0033] Both ends of the second opening groove 16 are rounded to avoid sharp corners and to guide the second adjusting rod 4 so that it can be easily inserted into the opening groove 16.

[0034] To further improve the strength of the fixing seat 1, the fixing seat 1 is provided with a first reinforcing rib 15, which is stamped and protrudes outward.

[0035] The mounting base 1 is also provided with a first weight reduction hole to reduce the weight of the mounting base 1.

[0036] To improve the strength of the adjustment seat 2, a connecting flange 21 is provided on the top of the adjustment seat 2, and an upper connecting hole 22 is provided on the connecting flange 21. The upper connecting hole 22 is connected to the seat cushion by screws. The adjustment seat 2 is formed by stamping sheet metal.

[0037] To further improve the strength of the adjusting seat 2 and prevent deformation of the adjusting seat 2, two second reinforcing ribs 23 are provided on the adjusting seat 2. The second reinforcing ribs 23 protrude inward to avoid interference with the fixed seat 1.

[0038] To facilitate the fixing of the first adjusting rod 3 and the second adjusting rod 4, a first retaining ring and a second retaining ring are also included. The first retaining ring is installed in the first retaining groove 31 at both ends of the first adjusting rod 3, and the first retaining ring is located on the outside of the fixing base 1. The second retaining ring is installed in the second retaining groove 41 at both ends of the second adjusting rod 4, and the second retaining ring is located on the inside of the adjusting base 2. The first retaining ring and the second retaining ring respectively realize the axial positioning of the first adjusting rod 3 and the second adjusting rod 4.

[0039] The height and fore-aft position of the seat can be adjusted according to the user's height to improve comfort. The seat can also be opened, making overall adjustment convenient, with a simple structure and low cost.

[0040] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
