Now, the research on the structural strength of the frame is in the industry. There are considerable bets on betting. Please refer to the sixth figure, which is a three-dimensional schematic diagram of a common conventional speed Keda locomotive frame, which comprises a tube (90A), a main support tube (8〇A) and two reinforcing rods (70A), the head tube ( 90A) for locating a locomotive faucet, the main support tube (80A) includes a main support tube (81A) extending downward from the head tube (90A), the main support tube (81A) Two end pipes (82A) are respectively arranged at the end of the lower end portion to extend outward and rearward, and then a rising portion 821 (821A) is formed upwardly, and the rising portion (821A) is further extended rearward to form a cushion support portion (822A). One end of the two reinforcing rods (70A) is fixed to the main support tube (81 A) of the main (8〇A), and the other end is fixed to the rising portion (821A) of the two side tubes (82A). In the above, the head pipe (90A) and the main support pipe member (8〇A) are only connected to the upper end portion of the main support pipe (81A), and are fixed at the lower end portion of the main support pipe (81A). Two reinforcing rods (70A), so the conventional speed Keda locomotive frame is easy to drive, and the external force is transmitted to the lower end of the main supporting tube (81A) by the head tube (90A), so that stress is concentrated on the main supporting tube The lower end of (81A) is combined with the two 201016529 reinforcing rods (70A), resulting in poor rigidity, which makes the locomotive faucet handle and the overall frame easy to sway during running, resulting in reduced handling. In addition, please refer to the national invention patent No. 1289523, and refer to the seventh figure, which mainly welds a main pipe (90〇) to the head pipe (90,), and the main pipe (7〇') extends downward and is fixed. On a front cross bracket (61,), the upper end re-welding side bobbin (60,) 'the side bobbin (60') has two side tubes (62, respectively) extending to both sides and downwardly, Both ends of the front cross bracket (61,) are welded to the upper ends of the two side tubes (62') of the two m-side bobbins (60,), and the upper end of the main tube (7〇,) is welded with a central skeleton (80. The lower extension # is used to strengthen the structure, and the head tube _') and the side tubes (62) of the side frame (60') are each welded with a corner plate (9),); The structural strength of the part (4) and (4) is strengthened by the various parts. However, the head tube (90,) has many parts welded, and there are many weld beads. The more the weld bead, the more likely the stress concentration is. The strength of 〇,,) itself will also be weak, and the side frame (6〇,) of the invention patent has a longer total length and is required for bending. Larger space, resulting in higher cost, so is the 'conventional scooter motorcycle rigid frame is pivoted on a head pipe leading locomotive still need to be strengthened' to increase maneuverability. SUMMARY OF THE INVENTION The main object of the present invention is to provide a frame for a skeletal locomotive frame which is designed to solve the disadvantages of the conventional skating locomotive frame. The poor rigidity of the saponins on the stalks is a pre-existing purpose.
