It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The present invention is described in further detail below with reference to specific examples, which should not be construed as limiting the scope of the invention as claimed. The term "comprising" when used indicates the presence of a feature but does not preclude the presence or addition of one or more other features; "first," "second," and the like are used to distinguish between different objects and are not limited to a particular order or number.
The electric coupler pushing device is arranged at the front end of the vehicle and is mainly used for driving the electric coupler to be normally coupled and separated so as to complete coupling, communication and the like between two vehicles.
The electric coupler pushing device mainly comprises a driving mechanism 7, a transmission mechanism, a supporting arm 2, an electric coupler mounting seat 1 and the like. The driving mechanism 7 provides driving force, and the transmission mechanism provides the driving force to the supporting arm 2 which is coupled with the electric coupler in a shaft mode, so that the electric coupler mounting seat 1 is driven to extend or retract.
As shown in fig. 1 and 5, the electric coupler pushing device includes: a support frame 8 which can play a role of bearing and supporting; the driving mechanism 7 provides driving force, the driving mechanism 7 comprises a fixed part 71 and a telescopic part 72, the fixed part 71 is supported on the support frame 8 through a fifth axis point F, and the telescopic part 72 can extend out of or retract from the fixed part 71 according to different working states of the electric coupler, wherein the driving mechanism can adopt an air cylinder or other components capable of realizing similar functions; a transmission mechanism connected with the telescopic part 72, wherein the transmission mechanism outputs the acting force of the driving mechanism 7 according to a specific direction and magnitude; and the driving force output by the transmission mechanism is transmitted to a supporting arm 2 of the electric coupler, one end of the supporting arm 2 is rotatably connected with the electric coupler mounting seat 1 at a first shaft point A, and the other end of the supporting arm is rotatably connected with the transmission mechanism at a second shaft point O. When the expansion part 72 extends from the fixing part 71, the transmission mechanism pushes out the electric hook mounting base 1. And when the telescopic part 72 extends out of the fixed part 71, the second axis point O moves towards the side where the driving mechanism 7 is located, and the design enables the internal space of the electric coupler pushing device to be effectively utilized, and space is reserved for installing other parts.
Holes are arranged at four corners of the electric hook mounting seat 1, and the holes at the four corners penetrate through the sliding guide rail and form clearance fit with the sliding guide rail. The electric coupler mounting base 1 slides along the sliding guide rail under the pushing of the driving force, so that the electric coupler extends out along the fixed direction, and the reliable guiding and positioning of the electric coupler in the extending or retracting process are ensured.
Fig. 2 shows the movement state of the transmission mechanism and the driving mechanism when the electric coupler is retracted, i.e. the transmission mechanism is arranged such that the second axis point O moves in the direction opposite to the side on which the driving mechanism 7 is located when the telescopic part 72 is retracted towards the fixed part 71. It can be seen from fig. 1 and fig. 2 that, in the extending and retracting movement process of the electric coupler, the movement locus of the second axis point O is basically above the connection line AB between the first axis point a and the first fixed hinge B, and this design leaves a space below the connection line AB, and other parts and components can be installed in the space.
Wherein, drive mechanism includes: connecting block 4, the one end of connecting block 4 is installed in support frame 8 through first fixed hinge B, and the one end of connecting block 4 is installed in the corresponding axle hole of support frame 8 through bracing piece 5 promptly. In the vertical direction Y, the position of the first fixed hinge B is slightly higher than the position of the first axis point a.
When the electric coupler needs to be pushed out, the cylinder telescopic part 72 extends out along the cylinder, the telescopic part 72 drives the second shaft point O to move towards one side direction of the cylinder, at the moment, the support arm 2 and the connecting block 4 move towards the horizontal state from the inclined state, so that the horizontal distance between the support arm 2 and the first shaft point A and the first fixed hinge B of the electric coupler mounting base 1 is increased, and the electric coupler mounting base 1 is pushed out. When the telescopic part 72 moves to the maximum stroke, the electric hook mounting base 1 is pushed out to the coupling position.
In the coupling position, the second shaft point O is slightly lower than a connecting line AB between the first shaft point a and the first fixed hinge B, when an external force pushes the electric coupler, the second shaft point O moves towards the direction of the side where the driving mechanism 7 is located, the cylinder has a tendency of being pulled, and as the cylinder extends to the maximum stroke position, the telescopic part 72 of the cylinder cannot extend continuously to prevent the second shaft point O from moving towards the direction of the side where the driving mechanism 7 is located, so that the electric coupler is prevented from retracting, and self-locking is formed.
When the coupling position is established, the supporting arm 2 is in a horizontal state and is consistent with the movement direction of the electric coupler, so that the thrust direction on the supporting arm 2 is consistent with the direction of the sliding guide rail of the electric coupler, the abrasion of the sliding guide rail is reduced, the vertical destructive force born by the electric coupler is reduced, and the stable structure of the electric coupler is favorably kept. Horizontal as used herein refers to a substantially horizontal, substantially horizontal orientation; also aligned with the electrical coupler guiderail direction is simply a substantially identical or substantially identical orientation of the position.
In the coupling position, when the piston rod moves to the maximum stroke, the supporting arm 2 is basically in a horizontal state, and the connecting block 4 is obliquely upwards at a small angle. The angle alpha formed by the connecting line AO of the first axis point A and the second axis point O of the supporting arm and the connecting line of the second axis point O of the connecting block 4 and the first fixed hinge B is required to satisfy alpha < 180 DEG, and the angle alpha is preferably required to satisfy 165 DEG < alpha < 180 DEG or 175 DEG < alpha < 180 deg.
The transmission mechanisms shown in fig. 1 and 2 are all four-bar mechanisms, and in actual use, the transmission mechanisms may be in the form of multi-bar mechanisms or single-bar mechanisms according to actual conditions, and are not limited to four-bar mechanisms.
Preferably, the transmission mechanism further comprises a pull rod 3 and a connecting rod 9 connected to the pull rod 3 in sequence. The other end of the connecting block 4, one end of the pull rod 3 and the supporting arm 2 are jointly pivoted on a second shaft point O. The connecting rod 9 and the pull rod 3 are axially connected with a third axis point C. Besides the first fixed hinge B, the transmission mechanism further includes a second fixed hinge D also disposed on the supporting frame 8, that is, the push rod 10 is fixed in the corresponding shaft hole of the supporting frame 8 to form the second fixed hinge D. One end of the connecting rod 9 is arranged on the supporting frame 8 through a second fixed hinge D. The first fixed hinge B is located at an upper portion of the second fixed hinge D in the vertical direction Y. In practical applications, the connecting line BD of the first fixed hinge B and the second fixed hinge D may not be perpendicular to the moving direction of the electric coupler according to requirements such as a spatial position, and the like, and the same effect can be achieved by adjusting the lengths of the pull rod 3 and the connecting rod 9, and the like. Preferably, the electric coupler is located on the same side of the transmission mechanism as the fixed part 71 of the driving mechanism 7, the first fixed hinge B and the second fixed hinge D. Due to the design, the size of the electric coupler pushing device in the X direction is reduced, the electric coupler pushing device is miniaturized, and the electric coupler pushing device can be installed in a small installation space.
When the electric coupler is under the action of external force, because alpha is less than 180 degrees, the second axis point O has a downward movement trend, but because the point O is provided with the pull rod 3, and the pull rod 3 cannot continue to move downwards because the cylinder expansion part 72 reaches the extending limiting position, at the moment, the push device of the electric coupler is in a self-locking state, and the electric coupler cannot retract. Since the connecting block 4 and the pull rod 3 are coupled to each other, only the reaction forces in the BO direction and the CO direction can be generated.
The second axis O is stressed as shown in fig. 3, and in the coupled position, the supporting arm 2 is subjected to an external force F which makes the electric coupler have a retraction tendencyAOIn order to achieve the force balance, the electric coupler pushing device needs to provide a reaction force with the same size and opposite directions under the condition that the electric coupler pushing device is self-locked. FBOFor reaction forces along the connecting piece 4, FBOCan be regarded as a reaction force in the horizontal direction X; fCOFor reaction forces along the pull rod 3, FCOCan be regarded as a reaction force in the vertical direction Y. It can be seen that the transmission mechanism is arranged to directly transmit the component force in the horizontal direction X from the electric coupler to the first fixed hinge B through the second axial point O of the support arm 2, that is, the component force in the horizontal direction X is transmitted to the support rod 5 through the connecting block 4, and since the support rod 5 is arranged on the support frame 8, the component force in the horizontal direction X equivalent to the electric coupler is directly applied to the support frame 8; while a smaller vertical Y force component caused by the electric coupler is transferred to the cylinder.
Since the angle alpha needs to satisfy alpha < 180 DEG, and the angle alpha preferably needs to satisfy 165 DEG < alpha < 180 DEG or preferably 175 DEG < alpha < 180 DEG, the reaction force F in the horizontal direction XBOIs much larger than the reaction force F in the vertical direction YCOI.e. constitute self-lockingMost of the reaction force is provided by the support frame 8, only a small part of the reaction force comes from the cylinder limiting device, the stress distribution is favorable for reducing the destructive force to the cylinder, the condition of providing larger supporting force for the electric coupler is provided, and the stability of connection of the electric coupler is favorably kept.
The utility model discloses an electric coupling pusher, first fixed hinge B's position sets up to being a little higher than primary shaft point A, stretches out limit position when cylinder pars contractilis 72, and electric coupling moves to linking the position of hanging, and the support arm is the horizontality basically this moment, 4 small-angle slant tops on the connecting block. This kind of design has avoided using the spacing electric coupling reaction force of directly overcoming of cylinder the utility model discloses in, electric coupling reaction is to the power of second axle point O, and its main horizontal component is directly transmitted to support frame 8 by support arm 2, connecting block 4, and only less vertical component has alleviateed cylinder stop device's burden through pull rod 3, connecting rod 9 transmission to cylinder stop device, has reduced the destructive power to driving actuating cylinder.
Preferably, the transmission mechanism further comprises a guide head 6 connected to a connecting rod 9, the connecting rod 9 and the guide head 6 are rotatably connected to the second fixed hinge D through a push rod 10, and the connecting rod 9 and the guide head 6 form a fixed V-shaped rod structure and simultaneously rotate around the push rod 10. The connecting rod 9 and the guide head 6 can be of an integrated V-shaped rod structure, and can also be of a structure which can rotate simultaneously and has a fixed relative angle and is formed by independent rods. The other end of the guide head 6 and the telescopic part 72 are coupled to a fourth axis point E. When the telescopic part 72 of the cylinder is pushed out, the telescopic part 72 drives the guide head 6 and the connecting rod 9 to swing to the position shown in fig. 1. At this time, the link 9 pulls the second axis point O downward through the third axis point C, the support arm 2 and the connection block 4 move from the inclined state of fig. 2 to the horizontal state of fig. 1, and the distance between the first axis point a and the first fixed hinge B is pushed to increase, that is, the electric coupler is pushed out. When the piston rod of the cylinder extends to the limit position, the electric coupler is pushed in place, and alpha is less than 180 degrees.
When the electric coupler needs to retract, as shown in fig. 2, the cylinder expansion part 72 retracts, the guide head 6 and the connecting rod 9 rotate clockwise for a certain angle around the second fixed hinge, the pull rod 3 pushes up the second axis point O under the driving of the connecting rod 9, the supporting arm 2 and the connecting block 4 move from a horizontal state to an inclined state, and the distance between the first fixed hinge B and the first axis point a is shortened, that is, the electric coupler retracts.

The double set of support arms structure can provide greater and more uniform thrust. The support arm 2 is provided with a compression spring which is an elastic support arm with adjustable length. By finely adjusting the lengths of the elastic supporting arms at the left side and the right side, part processing and assembling errors can be eliminated. After the electric coupler is connected, the thrust of the supporting arm 2 is perpendicular to the connecting surface, and the contacts on the left side and the right side of the electric coupler can be stably contacted.
