a driving motor 6 fixedly installed at the lower side of the tub 1 through a motor bracket 7;
And a screw rod 8 mounted at an output end of the driving motor 6 and screwed to the screw hole 3e of the screw rod connecting portion 3 a.
Through the above structural arrangement, the driving motor 6 drives the screw rod 8 to rotate, and the leg support supporting plate 5 can be driven to slide back and forth on the seat basin 1, so that the leg support can be automatically unfolded and retracted.
As shown in fig. 3, in order to prevent the leg rest support plate 5 from flying out of the seat pan 1 when the vehicle collides, the leg rest support plate 5 is provided with a drop-preventing strip groove 5a and a drop-preventing screw 5b, the drop-preventing screw 5b passes through the drop-preventing strip groove 5a to be screwed on the installation plane 1a of the seat pan 1, and when the leg rest slides back and forth, the drop-preventing strip groove 5a moves back and forth on the drop-preventing screw 5b, so that the normal use of the leg rest is not affected, and when severe collision occurs, the drop-preventing screw 5b can prevent the leg rest support plate 5 from flying out, so as to improve the safety performance of the leg rest.
As shown in fig. 3 to 6, the front end of the leg support supporting plate 5 is assembled with a cover plate 9, two ends of the cover plate 9 are provided with clamping grooves 9a with arc structures so as to facilitate the installation of a surface sleeve of a seat cushion, further, in order to facilitate the installation of the cover plate 9 on the leg support supporting plate 5, the front end of the leg support supporting plate 5 is distributed with positioning clamping holes 5d, the left end and the right end are provided with outwards extending clamping parts 5c, the inner side of the cover plate 9 is provided with positioning clamping blocks 9b matched with the positioning clamping holes 5d, two ends are provided with installation strips 9c extending towards the direction of the clamping parts 5c, the installation strips 9c are provided with inserting blocks 9d matched with the clamping parts 5c, and when the product is assembled, the inserting blocks 9d are inserted into the clamping parts 5c with hole structures, and then the positioning clamping blocks 9b are buckled into the positioning clamping holes 5d, so that the buckling can be completed. The cover plate 9 is further provided with cover plate screws 9e, and the cover plate 9 and the leg rest support plate 5 can be thoroughly and fixedly connected through the cover plate screws 9e so as to ensure the reliability of use.
As shown in fig. 5, 7 and 10, after the thigh leg rest is assembled, the leg rest support plate 5, the push block 4 and the connection block 3 are integrally connected by the fastening screw 10, specifically: the protruding portion 3b is provided with a threaded hole 3c, the leg support supporting plate 5 and the pushing block 4 are respectively provided with an upper screw through hole 5e and a lower screw through hole 4a, when the product is assembled, the protruding portion 3b of the connecting block 3 sequentially penetrates through the seat basin strip-shaped groove 1b and the slide seat strip-shaped groove 2a from bottom to top, the fastening screw 10 sequentially penetrates through the upper screw through hole 5e and the lower screw through hole 4a from top to bottom and is screwed into the threaded hole 3c of the protruding portion 3b, and the leg support supporting plate 5, the pushing block 4 and the connecting block 3 are fixedly connected.
As shown in fig. 8, a positioning bump 3d is provided on the protruding portion 3b, a positioning hole 5f is provided on the leg support supporting plate 5, a positioning post 4b corresponding to the positioning hole 5f is provided on the upper surface of the push block 4, and a positioning groove 4c corresponding to the positioning bump 3d is provided on the lower surface. When the product is assembled, the protruding part 3b of the connecting block 3 passes through the sliding seat bar-shaped groove 2a, then the pushing block 4 slides into the sliding seat, when the positioning groove 4c of the pushing block 4 is abutted on the positioning protruding block 3d of the protruding part 3b, the lower screw through hole 4a is opposite to the threaded hole 3c, then the positioning hole 5f on the leg support supporting plate 5 is positioned on the positioning column 4b of the pushing block 4, and at the moment, the upper screw through hole 5e is opposite to the lower screw through hole 4a, so by the structural design, the upper screw through hole 5e, the lower screw through hole 4a and the threaded hole 3c are opposite quickly, so that the positioning precision among all components is ensured, the tightening screw 10 is convenient to screw, and the assembled product has high strength and good reliability.
The slide seat 2 is provided with the chute 2b which is adaptive to the width of the push block 4, the middle position of the chute 2b is provided with the guide convex strip 2c which extends upwards, the lower surface of the push block 4 is provided with the guide chute 4d which is adaptive to the guide convex strip 2c, and the design can increase the smoothness of the sliding of the push block 4 on the slide seat 2.
As shown in fig. 1, in order to make the leg rest support plate 5 more firmly mounted on the upper side of the push block 4, the leg rest support plate 5 is further provided with a screw 12, and the screw 12 is screwed to the push block 4 through the leg rest support plate 5.
As shown in fig. 4, in order to meet the molding requirement of the basin 1, the front end of the basin 1 is provided with a punch-formed flange 1c, in the conventional mounting structure, the driving motor 6 is directly fixed on the flange 1c, and the flange 1c is arranged only to meet the external structure of the basin 1, so that the precision reference is poor, and therefore, the mounting precision of the driving motor 6 cannot be ensured when the driving motor 6 is mounted on the flange 1c, thereby affecting the coaxiality between the screw rod 8 and the threaded inner hole 3e and further affecting the smoothness of the sliding of the leg support. To overcome this problem, the driving motor 6 in the present embodiment is mounted on the underside of the tub 1 through a motor bracket 7.
Further, as shown in fig. 11 and 12, the motor bracket 7 is composed of a tub fixing portion 7a and a motor mounting portion 7b integrally formed, wherein the tub fixing portion 7a is fixedly connected with the lower surface of the tub 1, the motor mounting portion 7b extends downward along the front end of the tub fixing portion 7a, a speed reducing mechanism 6a is mounted at the output end position of the driving motor 6, and an outer casing 6b of the speed reducing mechanism 6a is fixedly mounted on the motor mounting portion 7b by a screw 11. Because the lower surface of the seat pan 1 is a flat surface, the machining precision of the seat pan is easier to ensure than that of the flange 1c, and therefore, the assembly precision of the driving motor 6 at the lower side of the front end of the seat pan 1 can be ensured through the fixed connection of the seat pan fixing part 7a and the lower surface of the seat pan 1.
For easy processing and assembly, the bowl fixing part 7a and the motor mounting part 7b are plate-shaped structures and are perpendicular to each other.
Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and that many similar changes can be made by those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
