[0040] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0041] The following is for reference. Figures 1-6 A vehicle stop device 100 according to an embodiment of the present invention is described, wherein the vehicle stop device 100 of the present invention is applied to a vehicle.

[0042] Combination Figures 1-6As shown, the stop device 100 of the vehicle according to the present application can mainly comprise: a first stop piece 10, a second stop piece 20, a third stop piece 30, a locking assembly 40 and a driving assembly 50, wherein the first stop piece 10 is arranged on the vehicle body, and the third stop piece 30 is arranged on the bogie 200, so that the stop device 100 can realize stop cooperation between the vehicle body and the bogie 200, to realize the conversion of the connection form between the vehicle body and the bogie 200.

[0043] Further, the second stop piece 20 is movably arranged above and below the first stop piece 10, so that the first stop piece 10 can not only provide a stable and reliable mounting position for the second stop piece 20, but also realize the up-and-down movement of the second stop piece 20 in the stop device 100 of the vehicle, to realize the operation of the stop device 100 of the vehicle. In addition, the third stop piece 30 is arranged below the first stop piece 10 and the second stop piece 20, and in the embodiment of the present application, the distance between the third stop piece 30 and the second stop piece 20 is generally 2-3 cm. In this way, when the vehicle is normally running, the third stop piece 30 and the first stop piece 10 are arranged at intervals, so as to avoid the collision between the first stop piece 10 and the third stop piece 30 during the running of the vehicle. When the vehicle is running abnormally, for example, the secondary suspension 300 is faulty or the vehicle is subjected to a major impact, the third stop piece 30 and the second stop piece 20 are in rigid contact, so as to realize the rigid connection between the vehicle body and the bogie 200, and protect the structure of the vehicle and the safety of the personnel in the vehicle body.

[0044] Further, the distance between the first stop piece 10 and the third stop piece 30 is greater than the distance between the second stop piece 20 and the third stop piece 30. Specifically, when the first stop piece 10 is in the interval position, at this time the vehicle is in a normal driving state, the first stop piece 10 and the second stop piece 20 are spaced apart from each other, and the distance between the first stop piece 10 and the second stop piece 20 is greater than the distance between the third stop piece 30 and the second stop piece 20, so that the first stop piece 10 can protect the second stop piece 20, and prevent the second stop piece 20 from being damaged by colliding with the third stop piece 30 during the running of the vehicle.

[0045] Further, the locking assembly 40 is movably arranged on the first stop piece 10, so that the first stop piece 10 can not only provide a stable and reliable structural position for the locking assembly 40, but also realize the movement reliability of the locking assembly 40 in the stop device 100 of the vehicle, so as to ensure the working reliability of the locking assembly 40.

[0046] Further, the driving assembly 50 is adapted to drive the second stopper 20 to move downward and abut against the third stopper 30, when the second stopper 20 and the third stopper 30 abut against each other, the locking assembly 40 moves toward the second stopper 20 and locks the second stopper 20 to prevent the second stopper 20 from moving upward. Specifically, the driving assembly 50 can provide power to the second stopper 20 to make the second stopper 20 move upward and downward on the first stopper 10, when the vehicle is working, the driving assembly 50 drives the second stopper 20 to move downward and abut against the third stopper 30, so that the third stopper 30 can limit the second stopper 20 from below, and the second stopper 20 and the third stopper 30 are in rigid contact, so as to realize the rigid connection between the vehicle body and the bogie 200.

[0047] In addition, when the second stopper 20 and the third stopper 30 abut against each other, the locking assembly 40 moves toward the second stopper 20 and the locking assembly 40 can lock the second stopper 20, the locking assembly 40 and the second stopper 20 are in rigid contact, not only can prevent the second stopper 20 from moving upward, ensure that the second stopper 20 and the third stopper 30 are always in rigid contact, but also can enhance the connection strength between the second stopper 20 and the third stopper 30, so as to realize the reliability of the rigid connection between the vehicle body and the bogie 200, so that when the vehicle is working, the vehicle body and the bogie 200 will not displace relative to each other, and the safety of the person working on the vehicle body can be improved.

[0048] Therefore, by setting the driving assembly 50 to drive the second stopper 20 to abut against the third stopper 30 downward, when the second stopper 20 and the third stopper 30 abut against each other, the locking assembly 40 prevents the second stopper 20 from moving upward, so that when the vehicle is working, the vehicle body and the bogie 200 can be in rigid contact, and the vehicle body and the bogie 200 will not displace, so as to improve the working safety of the vehicle.

[0049] In combination Figure 3 and Figure 6As shown, the driving assembly 50 comprises a first electromagnet 51 and a second electromagnet 52, the first electromagnet 51 is arranged at the lower end of the second stopper 20, the second electromagnet 52 is arranged at the upper end of the third stopper 30 and is opposite to the first electromagnet 51 vertically, the magnetic poles of the first electromagnet 51 and the second electromagnet 52 are different, so as to be attracted when energized. Specifically, the first electromagnet 51 is arranged at the lower end of the second stopper 20, the second electromagnet 52 is arranged at the upper end of the third stopper 30, and the second electromagnet 52 is opposite to the first electromagnet 51 vertically, so that the force generated between the first electromagnet 51 and the second electromagnet 52 can directly drive the second stopper 20 to move up and down in the first stopper 10, and the magnetic poles of the first electromagnet 51 and the second electromagnet 52 are different, so as to ensure that when the first electromagnet 51 and the second electromagnet 52 are energized, the first electromagnet 51 and the second electromagnet 52 generate stable mutual attraction force, and the second stopper 20 and the third stopper 30 can be tightly attracted together, so as to realize the rigid contact between the second stopper 20 and the third stopper 30, and then the rigid connection between the car body and the bogie 200, so that the car body cannot displace relative to the bogie 200, and the safety of the personnel on the car body during the operation of the vehicle can be improved.

[0050] In combination Figure 3 As shown, the stopper device 100 of the vehicle further comprises a first elastic member 60 connected between the upper end of the second stopper 20 and the first stopper 10 to exert an upward resetting force on the second stopper 20. Specifically, the first elastic member 60 is arranged and connected between the upper end of the second stopper 20 and the first stopper 10 in the stopper device 100, so that the upper end of the second stopper 20 is elastically connected with the first stopper 10. When the second stopper 20 moves downward, the first elastic member 60 is stretched and can exert an upward resetting force on the second stopper 20. Under the action of the resetting force, the second stopper 20 can quickly move upward and reset, so as to improve the resetting timeliness of the stopper device 100, so that the stopper device 100 can quickly reset after the operation of the vehicle is completed, without affecting the driving of the vehicle.

[0051] In combination Figure 3As shown, the locking assembly 40 is located on one side of the second stopper 20 in the left-right direction, and includes two first electromagnetic locking blocks 41 which are spaced apart in the left-right direction and have the same magnetic poles. When energized, the two first electromagnetic locking blocks 41 move in opposite directions, so that one of the first electromagnetic locking blocks 41 moves towards the second stopper 20 and abuts and locks the upper end of the second stopper 20 downward. Specifically, the locking assembly 40 is located on one side of the second stopper 20 in the left-right direction, and includes two first electromagnetic locking blocks 41 which are spaced apart in the left-right direction, so that the two first electromagnetic locking blocks 41 can move on one side of the second stopper 20 in the left-right direction. The two first electromagnetic locking blocks 41 have the same magnetic poles. When the two first electromagnetic locking blocks 41 are energized, the two first electromagnetic locking blocks 41 generate a repulsive force, so that the two first electromagnetic locking blocks 41 quickly move in opposite directions, so that one of the two first electromagnetic locking blocks 41 abuts and locks the upper end of the second stopper 20, thereby achieving the locking effect of the second stopper 20 in the up-down direction. In this way, the timeliness and convenience of the locking assembly 40 can be ensured, and the locking reliability of the locking assembly 40 on the second stopper 20 can be ensured.

[0052] In combination Figure 3 and Figure 6 As shown, the stopper device 100 of the vehicle further includes a second elastic member 70 connected between the two first electromagnetic locking blocks 41 to apply a restoring force to the two first electromagnetic locking blocks 41 to move closer to each other. Specifically, the second elastic member 70 is arranged between the two first electromagnetic locking blocks 41 to elastically connect the two first electromagnetic locking blocks 41. When the first electromagnetic locking blocks 41 are energized, the two first electromagnetic locking blocks 41 generate a repulsive force and move in opposite directions in the horizontal direction. At this time, the second elastic member 70 is stretched and applies a restoring force to the two first electromagnetic locking blocks 41 to move closer to each other. When the first electromagnetic locking blocks 41 are de-energized, the magnetic force of the first electromagnetic locking blocks 41 disappears, and under the action of the second elastic member 70, the two first electromagnetic locking blocks 41 quickly move closer to each other and reset, and the locking of the second stopper 20 in the up-down direction is released. In this way, the second stopper 20 can quickly move upward and reset under the action of the second elastic member 70, and the rigid connection between the vehicle body and the bogie 200 can be released, the vehicle can be converted from the working state to the running state, and the running stability of the vehicle can be ensured.

[0053] In combination Figure 3 and Figure 6As shown, the second stop 20 is two, two first electromagnetic locking blocks 41 are arranged between the two second stops 20, and the two first electromagnetic locking blocks 41 correspond to the two second stops 20 one by one. Specifically, the two second stops 20 are arranged to move up and down in the first stop 10, which can increase the structural stability when the second stop 20 abuts against the third stop 30, thereby improving the structural reliability when the car body and the bogie 200 are rigidly connected. The two first electromagnetic locking blocks 41 are arranged between the two second stops 20, and the two first electromagnetic locking blocks 41 correspond to the two second stops 20 one by one, so that the two first electromagnetic locking blocks 41 can lock the two second stops 20 respectively, and the locking reliability of the locking assembly 40 to the second stop 20 can be improved, thereby improving the working reliability of the stop device 100 of the vehicle.

[0054] In combination Figure 3 As shown, the third stop 30 is provided with a stop groove 31, the driving assembly 50 is adapted to drive the second stop 20 to extend into the stop groove 31, one side of the second stop 20 is provided with a locking hole 21, and the third stop 30 is provided with a second locking block 32.

Specifically, the third stop 30 is provided with a stop groove 31, and the driving assembly 50 is adapted to drive the second stop 20 to extend into the stop groove 31. In this way, not only can the third stop 30 limit the position of the second stop 20 below, but also can ensure that the contact position between the second stop 20 and the third stop 30 does not change when they abut against each other, which can prevent the second stop 20 from moving on the third stop 30, thereby ensuring the abutting reliability of the second stop 20 and the third stop 30.

[0055] Further, one side of the second stop 20 is provided with a locking hole 21, and the third stop 30 is provided with a second locking block 32. When the second stop 20 extends into the stop groove 31, the second locking block 32 is adapted to extend out from the side wall of the stop groove 31 in the left and right directions to lock with the locking hole 21, which can limit the movement of the second stop 20 in the up and down directions, and improve the reliability of the rigid abutment between the second stop 20 and the third stop 30, thereby ensuring the reliability of the rigid connection between the car body and the bogie 200, and ensuring that the car body and the bogie 200 do not displace during operation, thereby protecting the safety of the personnel on the car body.

[0056] In the embodiment of the present application, the second locking block 32 is a second electromagnetic locking block, there are two second electromagnetic locking blocks, and the two second electromagnetic locking blocks are arranged in the left-right direction with the same magnetic poles, so as to move reversely when powered on, and the two second electromagnetic locking blocks are locked with the locking hole 21 towards one of the stop grooves 31. Specifically, the second locking block 32 is arranged as a second electromagnetic locking block, and the two second electromagnetic locking blocks are arranged in the left-right direction, so that the two second electromagnetic locking blocks can move in the left-right direction, the two second electromagnetic locking blocks have the same magnetic poles, the two second electromagnetic locking blocks generate repulsive force to each other when the second locking block 32 is powered on, and the two second electromagnetic locking blocks are locked with the locking hole 21 towards one of the stop grooves 31, so as to realize the locking effect of the second stop piece 20 and the third stop piece 30.

[0057] In combination Figure 3 As shown, the second stop piece 20 is two, and the stop groove 31 is two, and the two second stop pieces 20 and the two stop grooves 31 correspond one by one. Specifically, the second stop piece 20 is two, and the stop groove 31 is two, and the two second stop pieces 20 and the two stop grooves 31 correspond one by one, so that the contact position of the second stop piece 20 and the second stop piece 20 can be increased, the abutment between the second stop piece 20 and the third stop piece 30 can be more stable, so as to improve the rigid connection reliability of the car body and the bogie 200, and further improve the operation safety of the vehicle.

[0058] In combination Figure 3 And Figure 5 As shown, the third stop piece 30 is provided with a travel switch 33, and the travel switch 33 is electrically connected with the two first electromagnetic locking blocks 41 and the two second electromagnetic locking blocks respectively, so as to control the on-off of the two first electromagnetic locking blocks 41 and the two second electromagnetic locking blocks. Specifically, the travel switch 33 is electrically connected with the two first electromagnetic locking blocks 41 and the two second electromagnetic locking blocks respectively, so as to control the on-off of the two first electromagnetic locking blocks 41 and the two second electromagnetic locking blocks, so that the vehicle can conveniently and reliably control the operation of the first electromagnetic locking block 41 and the second electromagnetic locking block through the travel switch 33, and the timeliness and reliability of the locking of the second stop piece 20 during the operation of the vehicle can be met.

[0059] Further, when the driving assembly 50 drives the second stopper 20 to abut against the third stopper 30, the second stopper 20 presses the travel switch 33, so as to energize the two first electromagnetic locking blocks 41 and the two second electromagnetic locking blocks. Specifically, the travel switch 33 is arranged on the third stopper 30, and when the driving assembly 50 drives the second stopper 20 to abut against the third stopper 30, the second stopper 20 can press the travel switch 33 at the same time, so that the travel switch 33 can control the two first electromagnetic locking blocks 41 and the two second electromagnetic locking blocks to be energized, so as to realize the locking of the second stopper 20 in the up-down direction by the locking assembly 40 and the second locking block 32, thereby ensuring the reliable abutment of the second stopper 20 and the third stopper 30, and improving the stability of the rigid connection between the vehicle body and the bogie 200.

Specifically, the third elastic member 80 is arranged between the two second electromagnetic locking blocks, so as to elastically connect the two second electromagnetic locking blocks. When the second locking block 32 is energized, the two second electromagnetic locking blocks generate a mutual repulsion force and move reversely in the left-right direction, at this time, the third elastic member 80 is stretched and applies a mutual approaching reset force to the two second electromagnetic locking blocks. When the second locking block 32 is de-energized, the magnetic force of the two second electromagnetic locking blocks disappears, and under the action of the third elastic member 80, the two second electromagnetic locking blocks quickly approach each other and reset, so as to release the locking of the second stopper 20 in the up-down direction, and the second stopper 20 and the third stopper 30 are converted from abutting against each other to being spaced apart, thereby releasing the rigid connection between the vehicle body and the bogie 200.
