Description

Technical Field

[0001] The utility model relates to the technical field of railway vehicles, in particular to a door lock structure of a vehicle. Background Art

[0002] Railway vehicles with closed compartments, such as railway boxcars and railway refrigerated cars, generally have multiple doors for closing the compartments. The doors are generally sliding or plug-sliding, where the plug-sliding door can be pressed into the door frame by a plug-pull device, and an anti-drop door lock structure is also provided to ensure safety.

[0003] The traditional Sierra sliding door generally includes a handle, a pull rod, a door shaft and a lock tongue arranged on the outside of the door body. During use, the handle on the outside of the door body is driven to rotate, thereby driving the pull rod to move, so as to drive the door shafts on both sides to rotate, and the lock tongues arranged on the door shafts rotate into the lock holes to form a lock. However, the transmission efficiency of the door lock structure of this Sierra sliding door is low, and the handle needs to be rotated multiple times to complete locking and unlocking. The lock tongue rotates into the lock hole, so the size of the lock tongue is limited and the matching accuracy requirements are high.

[0004] In order to reduce processing accuracy, improve transmission efficiency, and facilitate locking and unlocking operations, there is another type of Sierra sliding door body, in which a single-link-driven lock pin type anti-drop lock is set inside the door body. The rotation of the external handle drives the connecting rod to drive the lock pins on both sides to enter and exit the lock hole. However, in actual use, the lock pin is prone to deflection and is difficult to insert into the lock hole. Utility Model Content

[0005] The utility model aims to provide a vehicle door lock structure, which avoids deflection when a lock pin is inserted into a lock hole by improving the door lock structure, thereby improving the accuracy of the lock pin entering the lock hole.

[0006] To achieve the above-mentioned purpose, the utility model provides a door lock structure of a vehicle, wherein the vehicle includes a door body and a box body, and the door body and the box body are both provided with lock holes, and the door lock structure includes a lock pin, a driving member arranged on the door body, and a connecting rod drivingly connected to the driving member, one end of the connecting rod is hinged to the lock pin, and the driving member can rotate relative to the door body to drive the connecting rod to drive the lock pin to insert into or leave the corresponding lock hole along the plug-in direction; the door lock structure also includes a guide member arranged on the door body, and the guide member is provided with a guide channel, which extends along the plug-in direction and is opposite to the lock hole in the plug-in direction, and part of the lock pin is located in the guide channel.

[0007] By providing a guide member, the lock pin is prevented from being deflected during the transmission of the connecting rod; by providing a guide channel in the guide member, the guide channel extends along the plug-in direction of the lock pin and directly cooperates with the lock pin. When the connecting rod is deflected to a certain extent after the driving member is driven, the lock pin still moves along the plug-in direction under the limitation of the guide member, and is inserted into the lock hole opposite to the guide channel in the plug-in direction, thereby avoiding the problem of the lock pin being difficult to insert into the lock hole due to deflection during the insertion process.

[0008] Optionally, the driving member includes two first rods and two second rods, the first rods and the second rods are hinged end to end in sequence to form a quadrilateral, the two first rods are arranged opposite to each other in the plugging direction, and the second rods can rotate relative to the door body to drive the two first rods to move closer to each other or away from each other;

[0009] The connecting rod is hinged to the first rod; or,

[0010] The other end of the connecting rod is hinged to the position where the first rod and the second rod are connected.

[0011] In this embodiment, by providing a quadrilateral driving member structure, the two first rods can be driven to move closer to or farther from each other by rotating the second rod, thereby driving the lock pin to move along the guide member in the plugging direction. The quadrilateral driving member is relatively stable and can also rotate at least one second rod to drive multiple lock pins at the same time, which is easy to operate and efficient.

[0012] Optionally, it comprises at least two connecting rods and at least two locking pins, at least two locking pins are arranged opposite to each other in the width direction of the vehicle, the driving member is located between the two locking pins, and the connecting rods are hinged to the locking pins in a one-to-one correspondence.

By setting the spring rod structure, when the second rod rotates to the extreme position, the spring rod can press the second rod against the corresponding limit member, thereby keeping the second rod at the corresponding extreme position and preventing the second rod from reversing.

[0020] Optionally, the limit plate is made of a self-lubricating material. By adopting the self-lubricating material, when the outer wall of the locking pin contacts the limit plate, the friction between the locking pin and the limit plate can be reduced.

[0046] like Figure 1 and Figure 2 As shown, the utility model provides a door lock structure of a vehicle, the vehicle includes a door body 1 and a box body 2, both the door body 1 and the box body 2 are provided with lock holes, the door lock structure includes a lock pin 3, a driving member 4 arranged on the door body 1 and a connecting rod 5 transmission connected to the driving member 4, one end of the connecting rod 5 is hinged to the lock pin 3; the driving member 4 can rotate relative to the door body 1 to drive the connecting rod 5 to drive the lock pin 3 to insert into or leave the corresponding lock hole along the plug-in direction.

[0047] The specific structure of the driving member 4 of the present application is introduced below. The driving member 4 can be a single connecting rod hinged to the door body 1, one end of the connecting rod 5 is hinged to the single connecting rod, and the other end is hinged to the locking pin 3; in addition, the driving member 4 can also be a quadrilateral structure, the driving member 4 includes two first rods 41 and two second rods 42, the first rods 41 and the second rods 42 are hinged in sequence end to end to form a quadrilateral, the two first rods 41 are arranged opposite to each other in the plug-in direction, and the second rod 42 can rotate relative to the door body 1 to drive the two first rods 41 to approach or move away from each other.

[0048] As in Figure 1-Figure 4 In the scheme shown in , the plug-in direction is the horizontal direction, that is, the width direction of the vehicle. Of course, the plug-in direction can also be the vertical direction, that is, the height direction of the vehicle. The following takes the plug-in direction as the horizontal direction as an example to explain the driving member 4. The two first rods 41 extend in the height direction and are opposite in the width direction; the two second rods 42 are connected between the two first rods 41 and form a quadrilateral structure with the first rods 41. The second rod 42 is hinged to the door body 1. For example, the second rod 42 is hinged to the door body 1 through a rotating shaft. The rotating shaft has a cylindrical section and a driving section. The cylindrical section and the driving section are distributed along the axial direction. The cylindrical section is inserted into the door body 1. The driving section is inserted into the second rod 42 and forms a stopper with the second rod 42 along the circumferential direction. The cross section of the driving section is, for example, square, and the cross section of the cylindrical section is circular; optionally, the second rod 42 can be connected to a driving handle, and the second rod 42 is driven by the driving handle. Those skilled in the art can set it according to their needs.

[0049] As an alternative, Figure 1-Figure 4 In the example shown, the middle part of the second rod 42 is rotatably connected to the door body 1, and of course, the end of the second rod 42 can also be rotatably connected to the door body 1. The second rod 42 has two extreme positions, and the second rod 42 can rotate between the two extreme positions; the door lock structure includes two limit members, which can be structures such as bumps arranged on the door body 1 and protruding along the door body 1, and the two limit members are used to form a stop cooperation with the second rod 42 at the corresponding extreme positions; the door lock structure also includes a spring rod 7, one end of the spring rod 7 is hinged to the door body 1, and the other end is hinged to the end of the second rod 42; when the second rod 42 rotates to the extreme position, the spring rod 7 can press the second rod 42 to the corresponding limit member.

[0050] The spring rod 7 structure specifically includes a spring 71, a fixing rod 72 and a connecting rod 73. The spring 71 is inserted into one of the fixing rod 72 or the connecting rod 73 and can be deformed along the axial direction of the fixing rod 72 or the connecting rod 73. The fixing rod 72 is hinged to the door body 1, and the connecting rod 73 is hinged to the second rod 42. One end of the spring 71 is fixed to the fixing rod 72 as a fixed end, and the other end is fixed to the connecting rod 73 and serves as a movable end. The spring 71 is always in a compressed state. When the second rod 42 is in the extreme position, the spring 71 applies elastic force to the connecting rod 73 to press the second rod 42 against the limit member, thereby preventing the second rod 42 from rotating in the opposite direction.

[0051] In this way, the second rod 42 is pin-connected with the spring rod 7, and the spring rod 7 always provides thrust, so that the second rod 42 can be kept at two extreme positions, thereby preventing accidental movement. In other words, when the second rod 42 rotates to the extreme position, the spring rod 7 can press the second rod 42 against the corresponding limit member, thereby keeping the second rod 42 at the corresponding extreme position, preventing the second rod 42 from reversing.

[0052] In the above embodiment, the rotation center of the spring rod 7 is located on the extension line of the midpoint of the line connecting the two extreme positions and the line connecting the rotation axis, thereby ensuring that the elastic force of the spring rod 7 on the second rod 42 is consistent at the two extreme positions.

[0053] The transmission part of the door lock structure is described below. This solution adopts the transmission method of the connecting rod 5. Specifically, the other end of the connecting rod 5 included in the door lock structure is hinged at the position where the first rod 41 and the second rod 42 are connected. Of course, the connecting rod 5 and the first rod 41 can also be hinged. Those skilled in the art can choose. The door lock structure includes at least two connecting rods 5 and at least two lock pins 3. The at least two lock pins 3 are arranged on both sides of the vehicle in the width direction of the vehicle and are arranged opposite to each other. The driving member 4 is located between the two lock pins 3. The connecting rod 5 and the lock pins 3 are hinged one by one.

[0054] Specifically, in Figure 1-Figure 4 In the example shown, the door lock structure is provided with four connecting rods 5 and four locking pins 3. The four locking pins 3 are arranged in pairs on both sides of the vehicle in the width direction of the vehicle, and the two locking pins 3 on the same side are distributed up and down along the height direction of the vehicle; Figure 1 As shown, when the lock pin 3 is in the locked position, each connecting rod 5 extends in the horizontal direction, and the driving member 4 is in a rectangular structure; Figure 2 As shown, when the locking pin 3 is in the unlocking position, the second rod 42 is driven to rotate, thereby driving one of the two first rods 41 to move up and the other to move down, and the end of each connecting rod 5 hinged to the angular position of the quadrilateral driving member 4 moves in the height direction, while the distance between the two first connecting rods 5 is shortened in the width direction, thereby being able to drive the locking pin 3 to be pulled out of the lock hole.

[0055] By adopting the door lock structure of the present application, a second rod 42 can be controlled to rotate by setting a driving handle, and another second rod 42 is linked by pin connection with the first rod 41, one end of the connecting rod 5 is pinned to the position where the first rod 41 and the second rod 42 are connected, and the other end is pinned to the lock pin 3, so that the rotation of the second rod 42 is converted into the horizontal movement of the lock pin 3, thereby being able to drive four lock pins 3 at the same time through the quadrilateral structure, that is, the driving member 4 structure of the present application can drive the two first rods 41 to move closer to and away from each other by driving the second rod 42, thereby driving the lock pin 3 to move along the guide member 6 in the plug-in direction. The quadrilateral driving member 4 is relatively stable, and can also drive at least one second rod 42 to drive multiple lock pins 3 at the same time, which is easy to operate and efficient.

[0056] exist Figure 5 In Figures 8 to 8, the door lock structure in any of the above embodiments further includes a guide member 6 disposed on the door body 1. The structure of the guide member 6 is described in detail below. The guide member 6 can be disposed in any of the above embodiments. Specifically, the guide member 6 is provided with a guide channel, which extends along the plug-in direction and is opposite to the lock hole in the plug-in direction, and part of the lock pin 3 is located in the guide channel. The guide channel can have a continuous wall portion, and of course, its wall portion can also be in a discontinuous state, that is, the guide channel in the present application refers to a path or structure that allows the lock pin 3 to pass through it, and this path or structure can have a continuous wall portion or a discontinuous wall portion.

[0057] By providing the guide member 6, the lock pin 3 is prevented from being deflected during the transmission of the connecting rod 5. Specifically, a guide channel is provided in the guide member 6, which extends along the plug-in direction of the lock pin 3 and directly cooperates with the lock pin 3. When the connecting rod 5 is deflected to a certain extent after the driving member 4 is driven, the lock pin 3 still moves along the plug-in direction under the limitation of the guide member 6, and is inserted into the lock hole opposite to the guide channel in the plug-in direction, thereby avoiding the problem of the lock pin 3 being difficult to insert into the lock hole due to the deflection during the insertion process.

[0058] In this embodiment, a specific example is used to illustrate the scheme that the guide channel has a discontinuous wall portion. The guide member 6 includes at least two guide bodies 61 directly or indirectly connected to the door body 1, and each guide body 61 includes a guide hole portion, which is spaced apart and opposite in the plug-in direction, and the hole walls of at least two guide holes constitute the wall portion of the guide channel. That is, the guide channel can penetrate the guide body 61 in the plug-in direction and form two guide holes, and there is a gap between the guide holes so that the inner walls of the two spaced guide holes constitute the wall portion of the discontinuous guide channel.

[0059] By forming a wall of a guide channel with the walls of at least two guide holes, while ensuring the guiding function, the contact area between the locking pin 3 and the wall of the guide channel can be reduced by arranging the two guide holes opposite to each other in the plug-in direction to form a guide channel of a guide member 6, thereby reducing the friction between the locking pin 3 and the guide channel.

[0060] In an optional embodiment, each guide body 61 includes two limit plates 611 and two limit pins 612, the two limit plates 611 are spaced apart along a first direction (the width direction of the vehicle in the figure), and the two limit pins 612 are spaced apart along a second direction (the height direction of the vehicle in the figure), and the first direction is perpendicular to the second direction; the two limit pins 612 extend along the first direction and are rotatably connected to the limit plates 611, and a guide hole portion is formed between the limit plates 611 and the limit pins 612. In this way, rolling friction is formed between the limit pin 612 and the lock pin 3, thereby further reducing the friction between the lock pin 3 and the hole wall of the guide hole portion.

[0061] Optionally, the stop plate 611 is made of self-lubricating material. By using the self-lubricating material for the stop plate 611, when the outer wall of the lock pin 3 contacts the stop plate 611, the friction between the lock pin 3 and the stop plate 611 can also be reduced. The lock pin 3 moves in the guide member 6. In the height direction of the vehicle, the lock pin 3 rolls with the stop pin 612 on the top and bottom, and slides with the stop plate 611 made of self-lubricating material on both sides in the length direction of the vehicle. This has a small movement resistance, and the lock pin 3 is not easy to get stuck when entering and exiting the lock hole.

[0062] In a specific embodiment, the door body 1 further includes a plurality of support beams 11, and the guide body 61 further includes a mounting plate 613, which is connected to the support beams 11. When the lock pin 3 is located in the guide hole, the support beams 11 are spaced apart from the lock pin 3. By arranging the support beams 11 on the door body 1, the guide body 61 can be mounted on the support beams 11 through the mounting plates 613. At the same time, when the lock pin 3 is located in the guide hole, the lock pin 3 is spaced apart from the support beams 11, that is, there is a gap between the two, thereby preventing the support beams 11 from forming a stop on the lock pin 3 and increasing the friction resistance of the lock pin 3 during movement.

[0063] In a specific embodiment, the mounting plate 613 is provided with a through hole 613a, and the mounting plate 613 is provided with the through hole 613a to allow the locking pin 3 to pass through. When the locking pin 3 is located in the guide hole portion, the locking pin 3 is spaced apart from the hole wall of the through hole 613a. By spacing the through hole 613a of the mounting plate 613 from the outer wall of the locking pin 3, when the locking pin 3 passes through the mounting plate 613 and is plugged into the lock hole, the hole wall of the through hole 613a and the locking pin 3 do not contact each other, thereby avoiding friction between the through hole 613a of the mounting plate 613 and the locking pin 3.

[0064] Optionally, the guide body 61 further includes two side plates 614, and the two side plates 614 and the mounting plate 613 form a U-shaped structure; the limiting plate 611 corresponds to the side plates 614 one by one, and is connected to the inner wall of the side plates 614, and the locking pin 3 passes through the side plates 614 and the limiting plate 611. In this way, the structural strength of the limiting plate 611 can be increased, and the method of fixing the limiting plate 611 by the side plates 614 can improve the stopping force of the limiting plate 611 in the radial direction of the locking pin 3.

[0065] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
