The left frame 107 includes a plug board 116, a frame 117 and a side positioning pin 118. Through the foregoing solution, the problems that the existing engine connecting rod and the big end 103, the rod body 101 and the small end 102 of the automobile engine connecting rod are of an integral structure and need to be replaced as a whole when damaged after long-term use, thus increasing the use cost are solved.

[0021] For this specific embodiment, the small end 102 of the connecting rod is fixedly connected to the rod body 101 and is located at the top of the rod body 101. The big end 103 of the connecting rod is arranged at the bottom of the rod body 101. The small end 102 of the connecting rod is connected to a piston in the engine, and the big end 103 of the connecting rod is connected to a crankshaft in the engine, which can transmit the force received by the piston to the crankshaft and convert the reciprocating motion of the piston into the rotational motion of the crankshaft. The specific structures and usage methods of the big end 103, the rod body 101 and the small end 102 of the connecting rod are described in detail in the patent with the publication number CN207660702U, which is not within the protection scope of this application and will not be elaborated herein.

[0022] Among them, the upper connecting plate 105 is fixedly connected to the rod body 101 and is located on the side of the rod body 101 away from the small end 102 of the connecting rod. The lower connecting plate 106 is fixedly connected to the big end 103 of the connecting rod and is located at the top of the big end 103 of the connecting rod. The left frame 107 is slidably connected to the upper connecting plate 105 and the lower connecting plate 106 respectively and is located on the left side of the upper connecting plate 105. The right frame 108 is slidably connected to the upper connecting plate 105 and the lower connecting plate 106 respectively and is located on the right side of the upper connecting plate 105. The positioning member 109 is threadedly connected to the lower connecting plate 106 and passes through the upper connecting plate 105. By combining the upper connecting plate 105 at the bottom of the rod body 101 with the lower connecting plate 106 at the top of the big end 103 of the connecting rod and rotating the positioning member 109 clockwise, the lower connecting plate 106 is fixed to the bottom of the upper connecting plate 105, thereby fixing the big end 103 of the connecting rod to the rod body 101. At the same time, the left frame 107 and the right frame 108 are installed on both sides of the upper connecting plate 105 and the lower connecting plate 106, further fixing the positions of the upper connecting plate 105 and the lower connecting plate 106, which is convenient for workers to install the connecting rod into the engine. The split-type connecting rod can effectively improve the effect of the lightweight design of the engine. When the connecting rod is severely worn after long-term use and needs to be replaced, the worker can select and replace it according to the wear status of the big end 103 and the small end 102 of the connecting rod, avoiding the need to replace the whole connecting rod during replacement, reducing the use cost, and thus solving the problem that the existing engine connecting rod and the big end 103, rod body 101, and small end 102 of the automotive engine connecting rod are of an integral structure and need to be replaced as a whole when damaged after long-term use, increasing the use cost.

[0023] Secondly, the diversion frame 110 is fixedly connected to the small end 102 of the connecting rod and is located on one side of the small end 102 of the connecting rod. The storage frame 111 is fixedly connected to the diversion frame 110 and is located on one side of the diversion frame 110. When the engine is running, lubricating oil enters the diversion frame 110 from the diversion hole on the small end 102 of the connecting rod, assisting the cooperation between the small end 102 of the connecting rod and the engine piston, increasing the lubrication degree, and reducing the wear between the small end 102 of the connecting rod and the piston. After the lubricating oil enters the diversion frame 110, the excess lubricating oil enters the storage frame 111, which can ensure that there is always lubricating oil in the diversion frame 110 when the small end 102 of the connecting rod and the piston cooperate.

[0024] Again, the connecting plate body 112 is fixedly connected to the rod body 101 and is located at the bottom of the rod body 101. The convex block 113 is fixedly connected to the connecting plate body 112, is slidably connected to the lower connecting plate 106, and is located at the bottom of the connecting plate body 112. The fixing plate 114 is fixedly connected to the connecting plate body 112, is fixedly connected to the rod body 101, and is located on one side of the connecting plate body 112. The connecting plate body 112 is fixed to the bottom of the rod body 101, and the rod body 101 and the connecting plate body 112 are connected by the fixing plate 114 to make the connection more stable. By sliding the convex block 113 into the lower connecting plate 106, the rod body 101 moves accordingly, so that the rod body 101 and the big end of the connecting rod 103 can be connected and combined together to form a complete connecting rod.

[0025] In addition, the groove 115 is located at the top of the lower connecting plate 106. The convex block 113 can slide into the groove 115 of the lower connecting plate 106, and the positions of the connecting plate body 112 and the lower connecting plate 106 are fixed by the positioning member 109.

[0026] Meanwhile, the insertion plate 116 is slidably connected to the connecting plate body 112 and is located on the left side of the connecting plate body 112. The frame 117 is fixedly connected to the insertion plate 116 and is located on the side of the insertion plate 116. The side positioning pin 118 is threadedly connected to the insertion plate 116 and passes through the connecting plate body 112. After the positions of the upper connecting plate 105 and the lower connecting plate 106 are fixed by the positioning member 109, when the insertion plate 116 is slid into the connecting plate body 112, the frame 117 can abut against the connecting plate body 112 and the lower connecting plate 106. At this time, the side positioning member 109 can be rotated clockwise to pass through the connecting plate body 112 and the insertion plate 116, thereby fixing the position of the insertion plate 116 on the connecting plate body 112, and further making the connection between the upper connecting plate 105 and the lower connecting plate 106 more stable and preventing them from falling off during use.

[0027] A lightweight automobile connecting rod of the present utility model enables the bump 113 of the connecting plate body 112 to slide into the groove 115 of the lower connecting plate 106, and fixes the positions of the connecting plate body 112 and the lower connecting plate 106 through the positioning member 109. At the same time, after the insertion plate 116 slides into the connecting plate body 112, the frame 117 can abut against the connecting plate body 112 and the lower connecting plate 106. At this time, the side positioning member 109 can be rotated clockwise to pass through the connecting plate body 112 and the insertion plate 116, thereby fixing the position of the insertion plate 116 on the connecting plate body 112, making the connection between the upper connecting plate 105 and the lower connecting plate 106 more stable, facilitating workers to install the connecting rod into the engine. The split-type connecting rod can effectively improve the effect of the lightweight design of the engine. When the engine is running, lubricating oil enters the diversion frame 110 from the diversion hole on the small end 102 of the connecting rod, assisting the cooperation between the small end 102 of the connecting rod and the engine piston, increasing the lubrication degree, and reducing the wear between the small end 102 of the connecting rod and the piston. Moreover, after the lubricating oil enters the diversion frame 110, the excess lubricating oil enters the storage frame 111, which can ensure that there is always lubricating oil in the diversion frame 110 when the small end 102 of the connecting rod and the piston cooperate. When the connecting rod is severely worn after long-term use and needs to be replaced, the worker can select and replace it according to the wear conditions of the big end 103 and the small end 102 of the connecting rod, avoiding replacing the whole connecting rod during replacement, reducing the use cost, and thus solving the problem that the existing engine connecting rod and the big end 103, rod body 101, and small end 102 of the automobile engine connecting rod are of an integral structure and need to be replaced as a whole when damaged after long-term use, increasing the use cost.
