A guide device for a car coupler comprises a guide body,
the guide piece 2 is rotatably arranged on the coupler 1;
the connecting piece 3 is rotationally connected with the guide piece 2;
the driving piece 4 is arranged on the coupler 1, and a power output end of the driving piece 4 is rotatably connected with the connecting piece 3;

under the action of the driving element 4, the connecting element 3 can slide back and forth along the extending direction of the guide rail 5, so that the guide element 2 can extend and retract.
As shown in fig. 1, the guide 2 serves to increase the coupling guide range of the coupler 1 and at the same time to improve the coupling performance of the coupler 1. Specifically, the guide member 2 is an arc-shaped rod-shaped structure, one end of which is rotatably connected to the coupler 1, and the other end of which is rotatably connected to the connecting member 3. Further, a first rotating member 7 is arranged between the guide member 2 and the coupler 1, and the guide member 2 is rotatably arranged on the coupler 1 through the first rotating member 7. In the present embodiment, the first rotating member 7 is preferably a rotating shaft structure.
Specifically, one end of the connecting piece 3 is rotatably connected with the guide piece 2; further, in order to make the transmission effect between the guide member 2 and the connecting member 3 more excellent, a projection 21 is provided on the guide member 2, and the projection 21 is rotatably connected with the connecting member 3, so that the connecting member 3 and the guide member 2 are rotatably connected. The other end of connecting piece 3 slides and sets up in guide rail 5, and the power take off end of driving piece 4 rotates with connecting piece 3 and is connected, makes connecting piece 3 can make a round trip to slide along the extending direction of guide rail 5 under the effect of driving piece 4 from this to drive guide 2 and realize stretching out and retracting.
More specifically, the link 3 includes a first link end 31, a second link end 32, and a third link end 33. The first connecting end 31 is provided with a second rotating part 8, and the first connecting end 31 is rotatably connected with the guide part 2 through the second rotating part 8; the second connecting end 32 is rotatably provided with a sliding element 6, in this embodiment, the sliding element 6 is preferably a roller structure, and the structure of the sliding element 6 is matched with the structure of the guide rail 5, so that the second connecting end 32 is slidably connected with the guide rail 5, and the connecting element 3 can slide back and forth along the extending direction of the guide rail 5 under the action of the driving element 4. Meanwhile, the third connecting end 33 is provided with a third rotating part 9, and the third connecting end 33 is rotatably connected with the power output end of the driving part 4 through the third rotating part 9; and the third connection end 33 is disposed between the first connection end 31 and the second connection end 32. The guide piece, the driving piece, the connecting piece, the guide rail and the sliding piece are connected, so that the guide piece can form a self-locking state when extending out of place; when the guide member retracts to the proper position, the driving member enters a self-locking state.
The guide rail 5 serves to guide the guide member 2. Specifically, the guide rail 5 includes a first guide rail portion 51 and a second guide rail portion 52.
The first guide rail part 51 has an arc-shaped structure; the second guide rail part 52 is a strip-shaped structure, and the second guide rail part 52 is connected with the first guide rail part 51; and the second guide rail part 52 extends in a direction corresponding to the driving direction of the driver 4. Since the sliding member 6 is slidably disposed in the guide rail 5, the connecting member 3 can slide along the extending direction of the guide rail 5 under the action of the sliding member 6, so as to indirectly guide the rotation of the guide member 2, and the guide member 2 can be moved to a corresponding position more accurately. Specifically, under the action of the driving member 4, the connecting member 3 can slide from the first rail portion 51 to the second rail portion 52, and the retraction of the guide member 2 is realized; under the action of the driving member 4, the connecting member 3 can slide from the second rail portion 52 to the first rail portion 51 to extend the guide member 2 to the proper position. At the same time, when the drive element 4 is extended to the maximum stroke position, the guide element 2 is extended to the position required for operation. At this moment, the guide member 2 is forced to rotate clockwise in the working state, and the position relation among the guide member 2, the connecting member 3, the guide rail 5 and the sliding member 6 determines that the guide driving member can only extend out, and the guide driving member extends out to the maximum stroke position, so that a locking state is formed, and the guide member 2 is ensured to be in the state of extending out in place.
The driving member 4 is used for driving the connecting member 3 to rotate back and forth. When the vehicle is reconnected, the guide part 2 is extended to the position under the action of the driving part 4, the guide part 2 is retracted under the action of the driving part 4 after the reconnection is completed, the driving part 4 can be selected from automatic elements such as an air cylinder, an electric cylinder and a motor, and can also be driven manually, and in the embodiment, the driving part 4 is preferably an air cylinder.
Specifically, the driving element 4 is disposed on the coupler 1, and the driving element 4 is rotatably connected to the coupler 1. Further, a support 10 is arranged on the coupler 1, a fourth rotating part 11 is arranged on the support 10, and the driving part 4 is rotatably connected with the support 10 through the fourth rotating part 11, so that the driving part 4 is rotatably arranged on the coupler 1. Further, the driving member 4 is connected with the connecting member 3, and the connecting member 3 can drive the guiding member 2 to rotate under the action of the driving member 4, so that the extension and retraction of the guiding member 2 are realized. By adopting the structure, the guide member 2 is in a self-locking state when in the extending or retracting position, so that the guide member 2 is stably positioned at a required position. As can be seen from the above, the guide 2 in the retracted state significantly reduces the space occupied, making the structure compact. Therefore, the technical problem that the vehicle hood cannot be designed in a compact mode due to the fact that the guide piece 2 occupies a large space in the prior art is solved.
Furthermore, an elastic element (not shown in the figure) is arranged, one end of the elastic element is rotatably connected with the coupler, and the other end of the elastic element is rotatably connected with the sliding element. The guide can be prevented from being extended or retracted when the driving member malfunctions. By providing this spring, the guide 3 can be stably positioned even in the event of a failure of the drive 4.
For a clearer explanation of the present application, the working principle of the present invention will be further explained by taking the embodiments shown in fig. 1 to 6 as examples:
when the vehicle is reconnected, the power output end of the driving piece 4 moves towards the coupling direction of the coupler 1, so that the connecting piece 3 is driven to slide along the guide rail 5, and the guide piece 2 is connected with the connecting piece 3, so that the guide piece 2 extends out towards the coupling direction of the coupler 1 under the driving action of the connecting piece 3; when the slider 6 slides to the end of the first rail portion 51, the guide 2 is just protruded into position. At the moment, the guide part 2 is stressed to have a clockwise rotation trend in the working state, the position relation among the guide part 2, the connecting part 3, the guide rail 5 and the sliding part 6 determines that the guide driving part can only extend out, and the guide driving part extends out to the maximum stroke position, so that a locking state is formed, and the guide part 2 is ensured to be in the state of extending out to the right position. So that the guide 2 is stable in the desired position and the coupler 1 can be guided effectively. When the reconnection is completed, if the guide 2 extending to the right position needs to be retracted, firstly the guide 2 needs to rotate counterclockwise by a certain angle, and then the guide 2 is rotated clockwise under the action of the driving part 4. In other words, when the guiding element 2 retracts, the power output end of the driving element 4 moves towards the uncoupling direction of the coupler 1, so that the connecting element 3 is driven to slide along the guide rail 5, and the guiding element 2 is driven to rotate counterclockwise by a certain angle under the driving action of the connecting element 3 and then rotate clockwise to retract. When the guide part 2 retracts, the guide part 2 needs to rotate anticlockwise for a certain angle to prevent the guide part 2 from misoperation in the working process. When the slide 6 slides to the end of the second rail part 52, the guide 2 is retracted into position, where the drive member is self-locking, thereby preventing movement of the guide 2, so that the guide 2 is stable in the desired position. Therefore, the occupied space of the guide piece 2 is small, and the technical problem that the vehicle hood cannot be designed in a compact mode due to the fact that the occupied space of the guide piece 2 is large in the prior art is solved.

Specifically, in order to reduce the movement resistance of the link 3, the link 3 may be provided with only the first link end 31 and the second link end 32. The first connecting end 31 is rotatably connected with the guide member 2 through the second rotating member 8; the second connecting end 32 is provided with a third rotating part 9, the third rotating part 9 enables the second connecting end 32 to be rotatably connected with the power output end of the driving part 4, and meanwhile, the second connecting end 32 is also provided with a sliding part 6, namely, the connecting part of the driving part 4 and the second connecting end 32 and the sliding part 6 is rotatably connected. The guide piece, the driving piece, the connecting piece, the guide rail and the sliding piece are connected, so that the guide piece can form a self-locking state when extending out of place; when the guide member retracts to the proper position, the driving member enters a self-locking state. Thereby, the connecting element 3 can be slid back and forth along the extension direction of the guide rail 5 with less effort by the driving element 4.
Further, as shown in fig. 7 and 8, an elastic member is further provided, one end of the elastic member is rotatably connected to the coupler, and the other end of the elastic member is rotatably connected to the sliding member.
