DETAILED DESCRIPTION

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0028] like Figures 1-13 As shown, the present invention proposes a mini car bumper that is easy to assemble and splice. It includes a pair of bumper bodies 1, a Π-shaped block 15 and a pair of mounting and fixing legs 16 on the back of the bumper body 1. The two bumper bodies 1 are connected by the splicing and fixing assembly 2, and the bidirectional lead screw 3 is movably mounted on the splicing and fixing assembly 2.

[0029] The surfaces of the two bumper bodies 1 that fit together are provided with mounting grooves 12. Several L-shaped limiting claws 10 are provided in the mounting grooves 12. The L-shaped limiting claws 10 of the two bumper bodies 1 are staggered to avoid collision during splicing. A placement groove 13 is provided at the top of the mounting groove 12. A positioning groove 14 is provided in the placement groove 13. A pair of positioning posts 11 are provided on the bottom surface of the mounting groove 12.

[0030] In the assembly and fixing component 2, the fixing rod 20 is used to insert into the mounting slot 12. The bottom of the fixing rod 20 has several positioning slots 23. When inserted into the mounting slot 12, the positioning post 11 in the mounting slot 12 is inserted into the positioning slot 23. The top of the fixing rod 20 has a top plate 21, which is placed into the placement slot 13. The bottom of the top plate 21 has several positioning posts 22. These positioning posts 22 are inserted into the positioning slots 14 in the placement slot 13, thereby achieving a preliminary and stable connection between the two bumper bodies 1. The top of the top plate 21 has an inverted L-shaped plate 24, which is located on the back of the bumper body 1. The inverted L-shaped plate 24 is mounted on the mounting cylinder 25. The mounting cylinder 25 has a semi-open slot 26. A gear 28 is movably arranged in the semi-open slot 26 through a rotating shaft 27. One end of the rotating shaft 27 is exposed on the outside of the mounting cylinder 25. The mounting cylinder 25 has symmetrical sliding plates 211 on both sides.

[0031] Inside the mounting cylinder 25, a pair of bearing seats 212 are used to movably install a bidirectional lead screw 3. The section of the bidirectional lead screw 3 inside the mounting cylinder 25 is provided with a transmission tooth 30, which meshes with a gear 28. Drive cylinders 32 are symmetrically arranged on both sides of the bidirectional lead screw 3. A nut 33 is inside the drive cylinder 32 and is threadedly engaged with the bidirectional lead screw 3. A slider 34 is provided on the back of the drive cylinder 32. The slider 34 is movably arranged in the groove of the slide plate 211 to ensure that the drive cylinder 32 moves smoothly. Positioning inserts 35 are symmetrically installed on the upper and lower outer walls of the drive cylinder 32. After moving into position, the positioning inserts 35 are inserted into the Π-shaped block 15 to strengthen the connection of the bumper body 1.

[0032] Subsequently, after the positioning plate 35 is inserted, the double-acting screw 3 is rotated so that the first insertion holes 31 at both ends of the screw are aligned with the positioning holes 29 of the slide plate 211. The fixing rod 36 is inserted into the first insertion hole 31 until one end of it is inserted into the positioning hole 29. Then, the T-shaped rod 38 is taken out and inserted into the positioning hole 210 at the top of the slide plate 211, so that the T-shaped rod 38 passes through the second insertion hole 37 of the fixing rod 36. In this way, the double-acting screw 3 is locked to prevent the screw from rotating when the vehicle is bumpy, and to maintain the stable splicing state of the bumper body 1.

[0033] During installation, first take out two matching bumper bodies 1, locate the several L-shaped limiting claws 10 equipped with them, and accurately insert these L-shaped limiting claws 10 into the mounting slots 12 of the other bumper body 1, slowly and smoothly.

[0034] After the limiting claws are in place, the fixing rod 20 of the assembly and fixing component 2 can be inserted into the mounting slot 12. Note that it should be placed between the two sets of L-shaped limiting claws 10 (see Figure 6 for details) to effectively prevent the two bumper bodies 1 from sliding to the sides.

[0035] When the fixing rod 20 is successfully inserted, several positioning pins 11 will slide into the positioning slots 23. At the same time, as the fixing rod 20 is fully inserted into the mounting slot 12, the top plate 21 will fall precisely into the placement slot 13. Then, several positioning pins 22 will also be steadily inserted into several positioning slots 14 to achieve a stable connection.

[0036] After the above reinforcement is completed, the bidirectional lead screw 3 is now suspended in the middle of the two Π blocks 15. Then, reach out and hold the rotating shaft 27 and turn it manually. The rotating shaft 27 will drive the gear 28 to rotate. The gear 28 will mesh tightly with the transmission gear 30, which will then drive the bidirectional lead screw 3 to rotate. When the bidirectional lead screw 3 rotates forward, the screw nuts 33 on both sides will engage with it. The two drive cylinders 32 will then move outward smoothly in sync until the positioning plates 35 at their upper and lower ends are firmly inserted into the sockets of the two Π blocks 15, further strengthening the fixing effect.

[0037] After the positioning plate 35 is precisely inserted, rotate the lead screw slightly again to fine-tune it until the first insertion hole 31 is precisely aligned with the two positioning holes 29. Then take out the prepared fixing rod 36 and insert it horizontally from the first insertion hole 31. Push it forcefully until one end is fully embedded in the positioning hole 29. Next, pick up the two T-shaped rods 38 and align them with the two positioning holes 210 respectively. Then pass them through the second insertion hole 37 on the fixing rod 36. The double-acting lead screw 3 is firmly locked, and the lead screw will not rotate arbitrarily even if the vehicle is driving on a bumpy road.

[0038] After completing the above steps, the overall assembly of the bumper is complete. Finally, install the mounting legs 16 according to the reserved points on the vehicle body, tighten the fasteners and bolts, and fix the assembled bumper to the vehicle body.

[0039] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
