DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] To make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] This embodiment is a kart power transmission assembly with a protection structure.

[0026] As Figures 1-4 shown, it includes a gearbox 1. A base plate 2 is fixedly installed on the lower outer surface of the gearbox 1. Threaded holes 7 are opened at the four corners of the upper outer surface of the base plate 2. Bolts 3 are threadedly connected in the threaded holes 7. Chutes 8 are opened at the four corners of the upper outer surface of the base plate 2. The chutes 8 are located on one side of the threaded holes 7. A protection assembly 4 is arranged above the threaded holes 7. The protection assembly 4 includes a fixed block 9, an installation groove 10, guide rods 11, compression springs 12, a movable block 13 and a guide groove 14. The movable block 13 penetrates through the chute 8. Installation holes 5 are opened in the middle of both ends of the lower outer surface of the base plate 2. Pressure sensors 6 are fixedly installed in the installation holes 5, and the movable detection heads of the pressure sensors 6 extend outside the installation holes 5.

[0027] The fixed block 9 is located above the chute 8, and the lower outer surface of the fixed block 9 is fixedly connected to the upper outer surface of the base plate 2. The number of guide rods 11 and compression springs 12 in a set of protection assemblies 4 is two. The installation groove 10 is opened on the lower outer surface of the fixed block 9. The two guide rods 11 are fixedly installed on the left and right sides of the upper end of the installation groove 10. The compression spring 12 is movably sleeved on the outer wall of the guide rod 11. The upper outer surface of the compression spring 12 is fixedly connected to the upper end of the installation groove 10. The lower outer surface of the compression spring 12 is fixedly connected to the upper outer surface of the movable block 13. The guide grooves 14 are opened on the left and right sides of the upper outer surface of the movable block 13. The lower ends of the guide rods 11 extend into the upper ends of the guide grooves 14. The outer wall of the movable block 13 is slidably connected to the installation groove 10. The movable block 13 is slidably connected to the outer wall of the guide rod 11 through the guide groove 14. The upper outer surface of the movable block 13 is elastically connected to the upper end of the installation groove 10 through the compression spring 12.

[0028] It should be noted that the present utility model is a kart power transmission assembly with a protection structure. The gearbox 1 described in the text belongs to the prior art and can be effectively known to those skilled in the art, and will not be elaborated here. After the substrate 2 is fixed to the vehicle frame by the bolt 3, the pressure sensor 6 is squeezed, and the pressure sensor 6 measures the initial value. The pressure sensor 6 is externally connected to a controller. When the bolt 3 becomes loose, the pressure monitored by the pressure sensor 6 becomes smaller, and feedback can be made in a timely manner. For the provided protection assembly 4, after the substrate 2 is installed by the bolt 3, the movable block 13 is squeezed. The movable block 13 squeezes the compression spring 12 along the installation groove 10, and the movable block 13 slides along the outer wall of the guide rod 11 through the guide groove 14. After the substrate 2 is installed by the bolt 3, the compression spring 12 is in a squeezed state. Therefore, the reaction force released by the compression spring 12 increases the tension after the bolt 3 is connected, improving the stability of the threaded connection of the bolt 3.
