[0002] The connecting rod is one of the main transmission mechanisms of the automobile engine and an important part of the automobile engine. It connects the piston and the crankshaft, transmits the expansion gas pressure acting on the top of the piston to the crankshaft, and reversibly converts the reciprocating linear motion of the piston into the rotary motion of the crankshaft to output power. The connecting rod structure includes connecting the piston and the crankshaft, and transmitting the force exerted on the piston to the crankshaft, converting the reciprocating motion of the piston into the rotary motion of the crankshaft.

DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0019] Example 1: Please refer to Figure 1-Figure 10 The present invention provides a connecting rod structure based on an automobile assembly, including a first connecting rod body 1, a second connecting rod body 2, a bushing, a bearing and an adjusting component 3 with a locking function, wherein one end of the first connecting rod body 1 is slidably connected to one end of the second connecting rod body 2, and the adjusting component 3 is used to drive the relative sliding between the first connecting rod body 1 and the second connecting rod body 2 to generate a telescopic change in the length of the connecting rod.

[0020] Based on the above arrangement, when a small compression ratio or a high compression ratio is required, the first connecting rod body 1 and the second connecting rod body 2 can be driven to slide toward or away from each other by the adjusting component 3, thereby changing the length of the connecting rod to obtain a variable compression ratio; when the compression ratio is adjusted to the required compression ratio, the adjusting component 3 stops working, and the connecting rod length remains unchanged. At this time, the compression ratio remains constant.

[0021] An inserting section 11 is formed at one end of the first connecting rod body 1 relative to the second connecting rod body 2, and an open receiving cavity 21 is formed inside the end of the second connecting rod body 2 relative to the first connecting rod body 1. The receiving cavity 21 includes a limiting channel 211 that slides with the inserting section 11, and an adjustment cavity 212; the adjustment component 3 is arranged in the adjustment cavity 212.

[0022] Based on the above arrangement, in this embodiment, the plug-in section 11 of the first connecting rod body 1 is inserted into the limiting channel 211 of the accommodating cavity 21 to limit the sliding direction of the first connecting rod body 1. When adjusting the length of the connecting rod, the first connecting rod body 1 can be controlled to slide in the limiting channel 211 through the adjusting component 3, thereby realizing the overall length change adjustment of the connecting rod.

[0023] like Figure 3-Figure 5 As shown, the adjustment assembly 3 includes a pair of adjustment blocks 31, a driving member 33 and a scissor-type hinge assembly 32. The pair of adjustment blocks 31 are symmetrically slidably assembled on the left and right sides of the plug-in section 11 in the adjustment cavity 212, and the pair of adjustment blocks 31 can be driven by the driving member 33 to synchronously slide relative to or opposite to each other in a direction perpendicular to the telescopic direction of the connecting rod; The scissor-type hinge assembly 32 includes a central hinge shaft 321 and a scissor-type rod group 322 (such as Figure 5 As shown, symmetrical to plane P), the scissor-type rod group 322 includes a first hinge rod 3221 and a second hinge rod 3222 that are staggered and cross-arranged, the central hinge shaft 321 passes through the intersection of the first hinge rod 3221 and the second hinge rod 3222 of a pair of scissor-type rod groups 322, and the two ends of the central hinge shaft 321 are respectively connected to the adjustment cavity wall 2121 (as shown in FIG. Figure 1 as shown) for fixed connection.

[0024] The first hinged rod 3221 and the second hinged rod 3222 are both rotatably provided with a first hinged column 3223 at one end close to the plug-in section 11; the first hinged rod 3221 and the second hinged rod 3222 are both rotatably provided with a second hinged column 3224 at one end close to the adjusting block 31; the first hinged column 3223 is slidably connected to the plug-in section 11, and the second hinged column 3224 is slidably connected to the corresponding adjusting block 31; and when a pair of adjusting blocks 31 slide relative to or away from each other synchronously, the two first hinged columns 3223 on the scissors-type rod group 322 can move relative to or away from each other on the plug-in section 11, and the two second hinged columns 3224 on the scissors-type rod group 322 can slide on the corresponding adjusting block 31 along the telescopic direction of the connecting rod.

[0025] Based on the above arrangement, the present invention can drive a pair of adjustment blocks 31 to slide relative to or away from each other through a driving member 33, thereby making the first hinged rod 3221 and the second hinged rod 3222 of the two scissors-type rod groups 322 swing around the central hinge axis 321. During the swinging of the first hinged rod 3221 and the second hinged rod 3222, the first hinged column 3223 can drive the first connecting rod body 1 to slide in the limiting channel 211, thereby realizing the overall length adjustment of the connecting rod.

[0026] Specifically, when the length of the connecting rod needs to be shortened, a pair of adjustment blocks 31 move synchronously in opposite directions, and the angle between the first hinged rod 3221 and the second hinged rod 3222 of the scissors-type rod group 322 increases. The first hinged column 3223 of the scissors-type rod group 322 can drive the first connecting rod body 1 to move in the limiting channel 211 toward the adjustment cavity 212, thereby shortening the overall length of the connecting rod.

[0027] When the length of the rod needs to be increased, a pair of adjustment blocks 31 move relatively synchronously, and the angle between the first hinged rod 3221 and the second hinged rod 3222 of the scissors-type rod group 322 decreases. The first hinged column 3223 of the scissors-type rod group 322 can drive the first connecting rod body 1 to move in the limiting channel 211 away from the adjustment cavity 212, thereby increasing the overall length of the connecting rod.

[0028] It should be supplemented that, since the two ends of the central hinge shaft 321 are respectively fixedly connected to the adjustment cavity wall 2121, the "fulcrum" position always remains unchanged, and during the synchronous movement of a pair of adjustment blocks 31 in opposite directions, the second hinge column 3224 of the scissors-type rod group 322 can slide downward on the adjustment block 31 along the extension and retraction direction of the connecting rod, and the two first hinge columns 3223 on the scissors-type rod group 322 can move in opposite directions on the plug-in section 11; and during the relative synchronous movement of the pair of adjustment blocks 31, the second hinge column 3224 of the scissors-type rod group 322 can slide upward on the adjustment block 31 along the extension and retraction direction of the connecting rod, and the two first hinge columns 3223 on the scissors-type rod group 322 can move relatively on the plug-in section 11, so that the first hinge rod 3221 and the second hinge rod 3222 can swing normally, thereby completing the movement of the first connecting rod body 1 in the limiting channel 211.

[0029] In this embodiment, the distance between the first hinge column 3223 and the central hinge axis 321 is smaller than the distance between the second hinge column 3224 and the central hinge axis 321 .

[0030] In this embodiment, the driving member 33 includes a bidirectional screw rod 331 horizontally passing through the bottom of a pair of adjusting blocks 31, and a sliding rod 332 horizontally passing through the top of a pair of adjusting blocks 31, and the bidirectional screw rod 331 is threadedly connected to the pair of adjusting blocks 31 respectively.

[0031] Based on the above arrangement, when it is necessary to adjust a pair of adjusting blocks 31 to move away from each other or relative to each other, the bidirectional screw 331 (the threads at both ends rotate in opposite directions) needs to be rotated. The bidirectional threads of the bidirectional screw 331 cooperate with the threads of the pair of adjusting blocks 31 to complete the movement of the pair of adjusting blocks 31 away from each other or relative to each other, and the threads have a self-locking function. When the bidirectional screw 331 stops rotating, the pair of adjusting blocks 31 can stop moving.

[0032] In the present invention, the first hinged rod 3221 and the second hinged rod 3222 of the scissor-type rod group 322 can form a lever structure, wherein the central hinge shaft 321 can be a fulcrum, and in the first hinged rod 3221 and the second hinged rod 3222, the portion between the second hinged column 3224 and the central hinge shaft 321 can be a long arm, and the portion between the first hinged column 3223 and the central hinge shaft 321 can be a short arm; in the process of adjusting the overall length of the connecting rod, a pair of adjustment blocks 31 are used to drive the long arm to rotate, so that the short arm drives the first connecting rod body 1 to move in the limiting channel 211, which reduces the running load of the driving member on the one hand. , that is, the rotational torque of the bidirectional screw 331. On the other hand, during the working process of the connecting rod, when the first connecting rod body 1 is subjected to pressure or tension (it will frequently be subjected to pressure and tension during the connecting rod process), the first connecting rod body 1 will apply pressure or tension at the end of the short arm. When the pressure or tension is transmitted to the end of the long arm, it can be greatly reduced to avoid the pressure or tension received by the first connecting rod body 1 being directly transmitted to the pair of adjusting blocks 31, causing the pair of adjusting blocks 31 to be subjected to a large force, thereby causing the threads of the bidirectional screw 331 to be damaged, which not only extends the service life of the bidirectional screw 331, but also ensures the stability of the connecting rod during operation.

[0033] It should be noted that for the rotation of the bidirectional screw 331, a DC motor can be installed at one end of the bidirectional screw 331 to drive the bidirectional screw 331 to rotate. When in use, the DC motor can respond to external signals to control the quantitative rotation of the bidirectional screw 331, thereby achieving precise control of the connecting rod length.

[0034] In this embodiment, the two sides of the plug-in section 11 are symmetrically provided with sunken grooves 111, and the plug-in section 11 between the two sunken grooves 111 forms a strip-shaped connecting portion 112; a pair of scissor-type rod groups 322 are respectively located in the two sunken grooves 111, and a first strip-shaped vertical groove 113 is provided through the center position of the strip-shaped connecting portion 112, and the central hinge shaft 321 passes through the first strip-shaped vertical groove 113 and is adapted to the first strip-shaped vertical groove 113; A movable groove 114 is symmetrically passed through the strip-shaped connecting portion 112 above the first strip-shaped vertical groove 113, and a first sliding block 115 is slidably adapted in the movable groove 114. Figure 5 As shown, two ends of the two first sliding blocks 115 are fixedly connected to the two first hinged columns 3223 respectively; The adjusting block 31 is provided with a second strip-shaped vertical groove 311 , in which a second sliding block is slidably provided, and two ends of the two second sliding blocks are fixedly connected to the two second hinged columns 3224 , respectively.

[0035] Based on the above design, when the first connecting rod body 1 is in the sliding process of the limiting channel 211, the central hinge shaft 321 and the two first hinge columns 3223 of the pair of scissor-type rod groups 322 can perform three-point positioning on the first connecting rod body 1 to prevent the first connecting rod body 1 from radially swinging relative to the second connecting rod body 2 during operation.

[0036] In this embodiment, the movable groove 114 is arranged horizontally.

[0037] Example 2: Figure 6-Figure 10 As shown, on the basis of Example 1, the movable groove 114 is tilted, and a pair of movable grooves 114 are in an inverted eight-shaped shape. Compared with the horizontal arrangement of the movable groove 114 in Example 1, the tilted design of the movable groove 114 in this embodiment can increase the adjustment range of the connecting rod length on the one hand, and prevent the first connecting rod body 1 from swinging left and right relative to the second connecting rod body 2 during operation on the other hand.

[0038] Specifically, Figure 9-10 As shown, Fig. 9 and Fig.10 The first hinge rod 3221 and the second hinge rod 3222 in the embodiment swing at the same angle. Fig. 9 H in the figure represents the distance moved by the first connecting rod body 1; Fig.10 H 1 Indicates the distance moved by the first connecting rod 1; during the swinging of the first hinge rod 3221 and the second hinge rod 3222 around the central hinge shaft 321, the first hinge column 3223 moves in a circular motion around the central axis of the central hinge shaft 321. During this process, the first hinge column 3223 will undergo longitudinal and lateral displacements, such as Fig. 9 As shown, the movable groove 114 of the embodiment 1 is arranged horizontally, and the longitudinal displacement of the first hinge column 3223 is the distance that the first connecting rod body 1 moves relative to the second connecting rod body 2 (the length change value of the connecting rod); And as Fig. 9 As shown, the movable groove 114 of this embodiment is designed to be inclined, so the distance that the first connecting rod body 1 moves relative to the second connecting rod body 2 (the change in the length of the connecting rod) is the longitudinal displacement of the first hinge column 3223, plus the distance that the first hinge column 3223 pushes the second connecting rod body 2 to move during the lateral displacement (it can be understood that if the first hinge column 3223 only moves laterally, during this process, the first hinge column 3223 will also push the second connecting rod body 2 to move).

[0039] Furthermore, if the penetration direction of the movable groove 114 is horizontal, the first connecting rod body 1 may swing forward and backward relative to the second connecting rod body 2 during operation. To this end, in the penetration direction of the movable groove 114, the movable groove 114 includes symmetrical and inclined inclined groove portions 1141, and the two inclined groove portions 1141 are in an inverted eight-shaped shape. Correspondingly, the first sliding block 115 is an eight-shaped sliding block adapted to the shape of the inclined groove portion 1141, such as Figure 8 Based on the above arrangement, this embodiment can prevent the first connecting rod body 1 from swinging back and forth relative to the second connecting rod body 2 during operation, thereby avoiding affecting the stability requirement of the connecting rod during operation.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
