Specifically, the first support member 2 includes a first support portion 21 and a second support portion 22, the first support portion 21 is disposed on the coupler, one end of the second support portion 22 is fixedly connected to the first support portion 21, and the other end of the second support portion extends toward the end far away from the coupler connecting surface; and the first supporting part and the second supporting part are coaxially and fixedly connected. Because at the coupling direction in-process, first supporting part atress for make first supporting part atress even and can be stable set up on the coupling, design the cross section width of first supporting part for being greater than the cross section width of second supporting part in this embodiment. Further, the first support portion 21 is provided with a coupling hole through which the first rotating member 6 rotatably couples the first support portion 21 and the guide member 3.
Further, due to the space limitation in the coupler 1, the driving member 4 is directly connected to the guide member 3, and it is difficult to drive the guide member 3 to a corresponding position. In order to solve this problem, a second support 5 is provided between the driver 4 and the second support 22, i.e. one end of the second support 5 is connected to the second support 22 and the other end is rotatably connected to the driver 4. Meanwhile, the second support 5 is disposed at an angle with respect to the first support 2, and the angle is preferably 90 °. By providing this structure, the driving member 4 can drive the guide member 3 more efficiently; namely, the driving piece can be arranged at a corresponding position more conveniently by arranging the structure.
The guide 3 serves to increase the coupling guide range of the coupling 1 and at the same time to improve the coupling performance of the coupling 1.

The driving member 4 can be selected from automatic elements such as an air cylinder, an electric cylinder, a motor and the like, and can also be driven manually, and in the embodiment, the driving member 4 is preferably an air cylinder. In particular, the driving element 4 is arranged on the coupler 1 and is rotatably connected to the second support element 5, while its power take-off is rotatably connected to the guide element 3. When the vehicle is reconnected, the direction in which the driving piece 4 pushes the guide piece 3 to extend is consistent with the direction in which the coupler 1 is coupled, so that the guide piece 3 can play a role in guiding the coupler 1. At this time, the guiding member 3 is extended in a counterclockwise rotation and forms an included angle A with the first supporting member 21And A is1About 180 °; when the reconnection is completed, the driving part 4 drives the guide part 3 to retract, namely, the movement direction of the guide part 3 is consistent with the unhooking direction of the car coupler 1, the guide part 3 after the reconnection is completed rotates clockwise to retract, and the included angle between the guide part 3 and the first support part 2 is A2. It can be seen that the guide 3 in the retracted state has a significantly reduced footprint, resulting in a compact structure. Thereby solved among the prior art guide 3 occupation space big and lead to the technical problem that the vehicle hood can't realize compact.
In order to enable the driving part 4 to effectively apply the driving force to the guiding part 3, the first connecting part 9 and the second connecting part 10 are arranged between the guiding part 3 and the driving part 4, so that the driving part 4 can drive the guiding part 3 to move by driving the first connecting part 9 and the second connecting part 10, and the guiding part 3 can be quickly and accurately rotated to a required position.
Specifically, one end of the first connecting member 9 is rotatably connected to the guide member 3, and the other end thereof is rotatably connected to the power take-off end of the driving member 4. More specifically, the first link 9 is rotatably connected to the projection 31 of the guide 3. One end of the second connecting piece 10 is rotatably connected with the coupler 1, and the other end of the second connecting piece 10 is rotatably connected with the first connecting piece 9. In this embodiment, the first and second coupling members 9, 10 and the power take-off of the drive member 4 are rotationally coupled at a point. Furthermore, the first connecting piece 9, the second connecting piece 10 and the power output end of the driving piece 4 are in rotary connection through the arrangement of a second rotating piece 7, and the second rotating piece 7 is preferably in a rotating shaft structure. Under the action of the driving member 4, the first connecting member 9 and the second connecting member 10 are simultaneously rotated. Meanwhile, the first connecting piece 9 and the second connecting piece 10 are arranged at an angle, and the guide piece 3 can accurately and stably extend out by arranging the structure.
The guide piece can form a self-locking state when extending out of place through the connection among the guide piece, the driving piece, the first connecting piece, the second connecting piece, the first supporting piece and the second supporting piece; when the guide member retracts to the proper position, the driving member enters a self-locking state.
It should be further noted that, first, the rotational connection point between the projection 31 of the guide member 3 and the first connecting member 9 is referred to as a connection point a, the rotational connection point between the first connecting member 9, the second connecting member 10 and the driving member 4 is referred to as B, and the rotational connection point between the second connecting member 10 and the coupler is referred to as C. When the vehicle is reconnected, the driving part 4 extends to the maximum stroke position, and the connection point B is positioned at the outer side of the connection line of the connection point A and the connection point C. If the guide part 3 is stressed to have a clockwise rotation trend and the connection point B has a trend of moving towards the extending direction of the driving part 4, the driving part 4 cannot extend continuously at the moment, so that the guide part still cannot rotate, and self-locking is formed; therefore, the guide piece is in a locking state and is stably positioned at a corresponding position, and the guide function is effectively realized.
In order to prevent the guide 3 from being unstable in the respective position in the event of a malfunction of the drive element 4, an adjusting assembly 8 is provided in this embodiment. Specifically, the adjusting assembly 8 comprises an elastic element 81, one end of the elastic element 81 is fixedly connected with the coupler 1, and the other end of the elastic element 81 is connected with the connection position of the first connecting element 9 and the power output end of the driving element 4; when the driving member 4 is out of order, the guiding member 3 is prevented from moving in the retracting direction of the driving member 4 when in the extended position, and at the same time, the guiding member 3 is prevented from moving in the extending direction of the driving member 4 when in the retracted position. More specifically, the third adjusting assembly 8 further includes a third supporting member 82, a third rotating member 83, a fourth supporting member 84; the third supporting piece 82 is arranged on the coupler 1; the third rotating element 83 is disposed on the third supporting element 82, and the second connecting element 10 is rotatably connected to the third supporting element 82 through the third rotating element 83; the fourth supporting member 84 is disposed on the third supporting member 82, and the elastic member 81 is fixedly connected to the third supporting member 82 through the fourth supporting member 84. Further, in the present embodiment, the third supporting element 82 is preferably a rectangular block structure, the third rotating element 83 is preferably a rotating shaft, and the fourth supporting element 84 is preferably a fixed shaft structure.
Further, the third rotating member 83 is located on a different horizontal plane from the fourth supporting member 84.
When the guide member 3 is in the extended state, the included angle between the second connecting member 10 and the power output end of the driving member 4 is a1The included angle between the elastic element 81 and the power output end of the driving element 4 is alpha2And alpha1<ɑ2. By adopting the structural design, from the mechanical analysis, it can be seen that when the guide is in the position shown in fig. 3, that is, when the guide is in the extended state, if the driving member 4 fails at this time, the second rotating member 7 can be prevented from rotating under the tensile force of the elastic member 81, so that the retraction of the first connecting member 9, the second connecting member 10 and the driving member 4 is limited. At the same time, the drive member is now extended to the maximum position, so that the guide member 3 is in the extended and locked state. Therefore, the guide piece 3 is stably positioned at the corresponding position, and the coupling work of the coupler 1 is normally carried out.
When the guide member 3 is in the retracted state, the included angle between the second connecting member 10 and the power output end of the driving member 4 is a3The included angle between the elastic element 81 and the power output end of the driving element 4 is alpha4And alpha4<ɑ3. By adopting the structural design, from the mechanical point of view, it can be seen that when the guide is in the position shown in fig. 4, i.e. the guide is in the retracted state, if the driving member 4 fails at this time, the elastic member is in the elastic state81 to restrict the movement of the power take-off end of the first connecting member 9, the second connecting member 10 and the driving member 4 to the direction in which the guide member 3 extends, thereby ensuring that the guide member 3 is stably located at the corresponding position, and enabling the guide member 3 to be stably retracted after the vehicle reconnection is completed. Meanwhile, the driving piece is provided with a self-locking structure, so that when the driving piece retracts to the original state, the driving piece is self-locked, the guide piece 3 is prevented from moving, and the guide piece 3 is further ensured to be in a retracting and locking state. This ensures that the guide 3 can still be stably realized with a small space occupation in the event of a failure of the drive element 4, so that the vehicle hood assumes a compact configuration. Thereby solved among the prior art guide 3 occupation space big and lead to the technical problem that the vehicle hood can't realize compact.
For a clearer explanation of the present application, the working principle of the present invention is further explained below by taking the embodiment shown in fig. 1 to 4 as an example:

When the guide member 3 is extended into position, the driving member 4 is extended to the maximum stroke position, and the connection point B is located outside the line connecting the connection point a and the connection point C. If the guide part 3 is stressed to have a clockwise rotation trend and the connection point B has a trend of moving towards the extending direction of the driving part 4, the driving part 4 cannot extend continuously at the moment, so that the guide part still cannot rotate, and self-locking is formed; therefore, the guide piece is in a locking state and is stably positioned at a corresponding position, and the guide function is effectively realized.
When the reconnection is completed, the driving member 4 retracts to drive the first connecting member 9 and the second connecting member 10 to rotate simultaneously, and since the guiding member 3 is connected with the first connecting member 9, the guiding member 3 retracts towards the inner side of the hook connecting fine dried noodles under the driving action of the first connecting member 9, and when the driving member 4 retracts to the original position, the driving member enters a self-locking state, so that the guiding member 3 finishes retracting and is locked. The occupation space of the guide piece 3 is small, so that the technical problem that the vehicle hood cannot be compact due to the fact that the occupation space of the guide piece 3 is large in the prior art is solved.
Meanwhile, the adjusting assembly 8 is also arranged, when the guide piece 3 is in an extending state and the driving piece 4 breaks down, the second rotating piece 7 can be prevented from rotating under the action of the pulling force of the elastic piece 81, so that the retraction of the power output ends of the first connecting piece 9, the second connecting piece 10 and the driving piece 4 is limited, the guide piece 3 is stably positioned at a corresponding position, and the normal operation of the coupling operation of the coupler 1 is ensured;
when the guiding element 3 is in the retraction state, the second rotating element 7 can be prevented from rotating under the action of the pulling force of the elastic element 81, so that the extension of the power output ends of the first connecting element 9, the second connecting element 10 and the driving element 4 is limited, and therefore the guiding element 3 is stably located at the corresponding position, and the guiding element 3 can be stably in the retraction state after the vehicle reconnection is completed, and therefore the guiding element 3 can be stably realized in the failure state of the driving element 4, the occupied space is small, and the structure is compact. Thereby solved among the prior art guide 3 occupation space big and lead to the technical problem that the vehicle hood can't realize compact.

By adopting the above structure, when the vehicle is reconnected, the guide piece 3 extends to the working position, namely the guide piece 3 extends to the position and is locked under the driving action of the driving piece 4, and the guide piece 3 retracts and is locked after the reconnection is finished, so that the guide piece 3 occupies small space and has compact structure. Thereby solved among the prior art guide 3 occupation space big and lead to the technical problem that the vehicle hood can't realize compact.

3. The utility model discloses a set up the position relation between guide 3, first connecting piece 9, second connecting piece 10, driving piece 4, when the vehicle reconnection, driving piece 4 stretches out the maximum position of stroke, and rotation tie point B between first connecting piece 9, second connecting piece 10 and the driving piece 4 is in the outside of the rotation tie point A between lug 31 of guide 3 and first connecting piece 9 and the rotation tie point C line between second connecting piece 10 and the coupling. If the guide part 3 is stressed to have a clockwise rotation trend and the connection point B has a trend of moving towards the extending direction of the driving part 4, the driving part 4 cannot extend continuously at the moment, so that the guide part still cannot rotate, and self-locking is formed; therefore, the guide piece is in a locking state and is stably positioned at a corresponding position, and the guide function is effectively realized. After the reconnection is completed, the driving member 4 retracts to the original position and enters a self-locking state, and the driving member 4 drives the guiding member 3 to complete retraction and locking, so that the guiding member can be stably in a retracting state.
