Description of the invention (1) (Technical field to which the invention belongs) {Jing first read the precautions on the back and then fill out this page) The present invention relates to the interval between press-formed materials that are easy to manufacture and are joined by one pair. Resonance can also be prevented in a narrow situation. The vibration-proof structure of the body frame of a straddle-type vehicle (locomotive) that uses large vibration-damping blocks such as rubber with large attenuation effects can be used. (Prior art) There is a prior art regarding a body frame (Frame) in which a sheet material is press-formed so that a flange is formed (formed) at an end portion, and the flange and the flange are joined to this pair of formed members. : For example, as described in Japanese Patent Gazette ① JP-A 7-285483 "Body Frame of a Motorcycle", ② License No. 2 6 1 4 4 5 1 "Method for Manufacturing a Frame of a Motorcycle." In the above-mentioned prior art ①, as shown in FIG. 6 of the publication, there is described a technique in which the main body frame 8 and the bottom pipe 21 are respectively welded to the body frame of the plates 3 1 and 3 2 on both sides. The above-mentioned prior art ② states that, as shown in Figure 5 of this bulletin, it is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, welding the plate 61 and the plate 6i, and joining the plates 60, 60 to weld them. The technique of welding the welded plates 6 i, 6 i and the welded plates 6 0, 60 to the main skeleton 6 again. (Problems to be Solved by the Present Invention) In the above-mentioned prior art ①, the length of the plates 3 1, 32 spanning the main frame 8 and the bottom tube 2 1 becomes longer, so the central portion of the plates 3 1, 32 has a paper size. Applicable to China National Standard (CNS) A4 specification (210 * 297 mm) -4-4 A7 B7 V. Description of the invention (2) May be caused by the vibration of the engine and the same 6 〇 Harmonization may occur in order to prevent such 6 0 7 The technology described in 10-31 was printed by the Shellfish Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. In the above, the same cross section cuts the skeleton part 5 and the face 5 1 c is contracted, and the outer skeleton part 5 1 and the part 5 0 below 1 b are fused to the above-mentioned side divided skeleton, which requires a slightly orthogonal preparation. To further complicate matters, the side frame portion 5 may have a vibration effect or may need to be vibrated. The large width plate 60 in the prior art ② is described. For example, please refer to Japanese Patent Gazette ③ JP-A-4 "Main Frame Structure of Motorcycle". Please read the back part of the front, the hyphenated 0, and the upper end of the side divider. 5 The angle of the previous part 5 1 is not the same as the direction of the rule. If the outer 1's flat oak takes the main technique ③ the surface is 3 and the inner part 5 is compressed into the skeleton part 5 1 0 b and the shape section ③ The cross section of the cross section is fixed at a load and spot welding is appropriate. The side 5 is glued, so the skeleton 5 is described. The outer part 5 0 c of the figure is cut on the inside and the upper part a of the upper part 5 0 is welded to the inner side for vibration isolation. The main skeleton 5 of the bone is shaped because the outside is 3-shaped, and the compression rubber 7 is welded. The interval of the skeleton part 5 0 1 c is the same as that of the male segmented bone 1 with the natural vibration that needs to be taken, the same as the rubber part 50 of the segmented bone, and the technology of the frame part 5 is divided into the skeleton part 50 shown in FIG. 5. At the time, the outer frame part 5 1 is flat 7 1 and pressed a and the inner part is divided from the outer part frame 1 and the lower end 5 of the frame part 5 0 and the inner part. Therefore, a main frame 5 1 is to be manufactured. One side has a main frame 5 from the compression side. When the flat part 5 0 c of the manufacturing equipment is narrow and the inner part is not inserted, the number of positions of the rubber 7 1 cannot be changed. It will not be attached to the engine's favorite items. I The page size of this page applies to China National Standard (CNS) A4 specifications ( 210 * 297 mm) -5-Α7 Β7 V. Description of the invention (3) Countermeasure of preventing vibration due to the number of vibrations. Therefore, an object of the present invention is to provide a straddle-type vehicle in which: ① the manufacturing equipment is simplified and easily manufactured. ② A narrow gap between a pair of press-formed materials can still prevent resonance, and a narrow-space gap between a pair of press-formed materials can still use large anti-vibration blocks such as large rubber. The vibration-proof structure of the skeleton is also. (Means for solving the problem) In order to achieve the above-mentioned object, the vibration-proof structure of the body frame of the straddle-type vehicle described in the scope of patent application No. 1 is mainly a superposition: the bottom, and the walls rising from both ends of the bottom One of the cross sections formed by the upper end of these wall sections and the flange sections extending leftward and rightward, respectively, is a pair of press-formed materials, which are each convex. The edge makes it a closed cross-section vehicle. The body frame is characterized in that one end of a vibration-proof block that forms a function of suppressing the vibration of a vehicle body frame is mounted on one press-molded material, and the other press-molded material is used to compress the other end of the vibration-proof block and join The flanges and flanges of the two press-formed materials are used to install the anti-vibration block on the car body frame. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. One end of a vibration-proof block that suppresses the vibration of the car body frame is installed on one side of the pressed molding material. The flange portion of the molding material is used to compress the other end of the vibration-proof block by the other pressing molding material, and the flange portion and the flange portion of the two pressing molding materials are welded by spot welding. As a result, during spot welding, the electrode was used to compress the anti-vibration block on the other side of the press-formed material, and welding was performed on the other side. Therefore, the Chinese national standard (CNS> A4 (210 X 297) (Centi) -6-A7 B7 V. Description of the invention (4) When the direction of the compression rubber is not the same as the direction of joining a pair of press-formed materials, the compression direction of the anti-vibration block and the addition of spot welding are added. The direction is the same direction, so the pressure of the spot welding can be used for compression of the vibration-proof block. No special device for the compression of the vibration-proof block is needed, and the manufacturing equipment of the vehicle body skeleton with the vibration-proof structure can be made. The simplification and easy manufacture of the car body frame with anti-vibration structure. The anti-vibration structure of the car body frame of the straddle-type vehicle with the scope of patent application No. 2 is mainly superimposed: the bottom, and the bottom two One of the cross-sections formed by the raised wall portions and the flange portions extending from the upper ends of the wall portions to the left and right respectively is a press-molded body that joins the flanges to form a closed-section structure. In the body frame of the straddle-type vehicle thus formed, each of them is formed by pressing from the bottom of the pair of press-formed materials to approach each other. A convex portion is formed by joining the convex portion and the convex portion. The component that suppresses the vibration that occurs at the bottom. Joins the convex part and convex part that are pressed from the bottom of a pair of press-formed materials and are close to each other to change the natural vibration number of the car body frame. The result is that the vibration occurring at the bottom is suppressed. The result is that the interval between the bottoms of a pair of press-formed materials is narrow, and it is not easy to interpose vibration members such as anti-vibration blocks between the pair of press-formed materials. Vibration is not affected by the interval between the bottom of the car body frame, and this vibration-proof structure can be applied. In addition, when using spot welding for bonding, for example, one side can be welded by pressing the electrode for spot welding. The flange part and the convex part make it easy to manufacture the car body frame with anti-vibration structure. At the same time, the paper size can be adapted to the Chinese National Standard (CNS) A4 (210 X 297 mm). Read the note on the back and write this page.

Description of the invention (17) The Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed 92d '92d and the convex portions 91b and 92b, and the pressure is usually used for spot welding. In addition, the joining method of the vehicle body frame of the present invention is not limited to spot welding, but projection welding may also be used. The anti-vibration member (vibration absorbing member) of the present invention is not limited to rubber, and a damping force generating mechanism such as an air buffer 'oil pressure buffer may be used. ] The straddle-type vehicle that can be used for the vibration-proof structure of the body frame of the present invention is not limited to a field-walking vehicle such as a two-wheeled vehicle (locomotive), a cart, or the like. Be applicable. (Effects of the Invention) The present invention has the above-described configuration and can exhibit the following effects. The anti-vibration structure of the body frame of the straddle-type vehicle of the scope of application for the patent is the anti-vibration that will suppress the vibration of the body frame. One end of the block is installed on one side of the pressed molding material, and the other side is pressed. The molding material is used to compress the other end of the vibration-proof block, and the flanges and flanges of the two pressed molding materials are joined, so that the vibration-proof block is installed on the car body frame. Therefore, for example, during spot welding, an electrode for spot welding can be used. On the other hand, the compression vibration block can be welded on the other side through the press-formed material. When compared with the difference between the direction of the compression rubber of the prior art and the direction of joining a pair of press-formed materials, The compression direction of the vibration isolation block is the same as the pressure direction of the spot welding fusion, so the pressure for spot welding fusion must be compressed to the compression of the vibration isolation block. Therefore, there is no need to provide a special compression compression compression block. The device can simplify the manufacturing equipment of the car body frame with anti-vibration structure, and at the same time it is very

Description of the invention 〇8) It is easy to manufacture car body skeleton with anti-vibration structure. Therefore, it is possible to reduce the manufacturing cost of a car body frame with a vibration-proof structure. The anti-vibration structure of the vehicle body frame of the straddle-type vehicle in the scope of the patent application No. 2 is formed by pressing and forming protrusions from the bottom of the pair of press-molded materials to approach each other. The joint is constituted by suppressing the vibration occurring at the bottom. Therefore, the gap between the bottoms of the pair of press-formed materials is narrow, and it is difficult to interpose vibration absorption members such as anti-vibration blocks between the pair of press-formed materials, which can still suppress the bottom vibration without being affected by the car. The interval of the bottom of the body frame can be applied to the vibration isolation structure. At the time of joining, for example, when spot welding is used, welding can be performed at one time by pressing the flange portion and the convex portion with electrodes for spot welding, so that it is easy to manufacture a car body frame with a vibration-proof structure. It is possible to simplify the manufacturing equipment of a car body frame having a vibration-proof structure.
