Description

Technical Field

[0001] The present application relates to the field of engineering machinery technology, and in particular to a vehicle door locking mechanism. Background Art

[0002] Trackless vehicles for mining are suitable for non-explosion-proof diesel-driven trackless vehicles that travel in ramps and (or) tunnels of metal and non-metal underground mines. The doors of emergency exits of trackless vehicles should be equipped with door locking mechanisms, which should be locked when closed, and the emergency doors should not open automatically due to vibration, bumps, or collisions when the trackless vehicle is in motion. When the trackless vehicle is stationary, the emergency doors should be able to be opened from inside and outside the vehicle without tools.

[0003] The prior art is to weld a side door fixing seat on the carriage, and the door ring assembly can rotate around the axis on the fixing seat through bolt connection. A groove is processed at the blocking plate on the door ring. When the door ring is lifted to open the emergency door, the groove is clamped by the rotation of the rotating shaft so that the pin shaft welded on the side door fixing seat is clamped, thereby achieving the limit after the door is opened. When the emergency door needs to be closed, the door ring assembly is rotated so that the pin shaft on the side door fixing seat is clamped on the edge of the door ring, thereby achieving the door closing limit. There are two disadvantages in doing so. First, the positioning of the pin shaft slot is relatively rough and the gap is large. Therefore, after opening and closing the emergency door many times, the door ring will sag when the car door is closed, and it will not be perpendicular to the ground, which is not beautiful and the safety is also affected. Second, considering the extreme situation of the force on the door of the person, the car, and the door, someone has been pressing the door ring assembly with all his strength for a long time, so that the joint between the pin shaft and the door ring on the side door fixing seat is deformed and the door ring is flattened.

[0004] In order to improve the safety and life of a vehicle door locking mechanism after long-term use, we propose a vehicle door locking mechanism. Utility Model Content

[0005] In order to improve the safety and life of a vehicle door locking mechanism after long-term use, the present application provides a vehicle door locking mechanism.

[0006] The present application provides a door locking mechanism that adopts the following technical solution:

[0007] A vehicle door locking mechanism comprises a door ring assembly and a side door fixing seat, wherein the door ring assembly is connected to the side door fixing seat, and a limit assembly is provided at the connection between the door ring assembly and the side door fixing seat, wherein the limit assembly limits the relative position of the door ring assembly and the side door fixing seat so that the door ring assembly can be parallel to the ground when opened; the door ring assembly is rotatably connected to the side door fixing seat, and the limit assembly comprises a first half shaft and a second half shaft, wherein the first half shaft is located on the door ring assembly, so that during the rotation of the door ring assembly around the side door fixing seat, the first half shaft of the door ring assembly rotates to a position that is in contact with the side surface of the second half shaft on the side door fixing seat, so that the second half shaft limits the rotation space of the first half shaft, thereby limiting the position of the door ring assembly on the side door fixing seat.

[0008] By adopting the above technical scheme, a limit assembly is provided between the door ring assembly and the side door fixing seat, and the position of the door ring assembly is limited by limiting the connection position between the door ring assembly and the side door fixing seat. The limit assembly provides more supporting force to the door ring assembly to improve the stress condition of the connection position between the door ring assembly and the side door fixing seat. On the one hand, more supporting force enables the door ring assembly to be stably in a position parallel to the horizontal ground when closed, thereby blocking people and preventing the door ring assembly from being perpendicular to the horizontal ground due to aging due to long-term use, thereby increasing the safety of the door locking mechanism. On the other hand, by providing more supporting force at the connection between the door ring assembly and the side door fixing seat, the door ring assembly and the side door fixing seat are made more solid, preventing deformation of the joint, thereby extending the service life of the door locking mechanism. In specific implementation, the door ring assembly and the side door fixing seat will encounter mutual obstruction between the first semi-axis and the second semi-axis during the process of rotational connection. The side wall of the first semi-axis fits the side wall of the second semi-axis, so that the rotation process space is limited and cannot continue to rotate.

[0009] Preferably, the first semi-shaft is provided with a first semi-shaft left boss and a first semi-shaft right boss, and the first semi-shaft left boss is arranged opposite to the first semi-shaft right boss, and the second semi-shaft is provided with a second semi-shaft left boss and a second semi-shaft right boss, and the second semi-shaft left boss and the second semi-shaft right boss are arranged opposite to each other, and the positions of the first semi-shaft left boss and the first semi-shaft right boss are opposite to the positions of the second semi-shaft left boss and the second semi-shaft right boss, so that when the first semi-shaft rotates, the boss position of the first semi-shaft contacts the boss position of the second semi-shaft.

[0010] By adopting the above technical solution, the boss is at the end of the half shaft, so that the first half shaft and the second half shaft will first encounter the boss of the other party during the rotation process, so that the overall force of the connecting surface of the two is better.

[0011] Preferably, the upper surface of the left boss of the second semi-shaft is parallel to the horizontal plane, so that when the lower side of the right boss of the first semi-shaft is in contact with the upper side of the left boss of the second semi-shaft, the door ring assembly is parallel to the horizontal plane, and the upper surface of the right boss of the second semi-shaft has an angle with the horizontal plane, so that when the upper side of the right boss of the first semi-shaft is in contact with the upper side of the right boss of the second semi-shaft, the door ring assembly tilts to the right at a certain angle and will not fall down by itself without adding external force.

[0012] By adopting the above technical solution, the door knocker assembly is located at different positions by rotating on the side door fixing seat, so that the door knocker assembly has two states: blocking people and not blocking people. When the door knocker assembly is perpendicular to the ground, the strength of the door knocker assembly in blocking people reaches an optimal level. When the door knocker assembly is tilted to the right at a certain angle, the door knocker assembly will not fall down by itself.

[0013] Preferably, light holes are opened on the door knocker assembly and the side door fixing seat, and a rotating bolt is provided in the light hole. The rotating bolt is used to connect the door knocker assembly and the side door fixing seat so that the door knocker assembly and the side door fixing seat are rotatably connected; and a locking nut is provided on the rotating bolt.

[0014] By adopting the above technical solution, the door knocker assembly is rotationally connected to the side door fixing seat by rotating the screw.

[0015] Preferably, an induction connection component is further provided between the door knocker assembly and the side door fixing seat, and the induction connection component determines the connection status of the door knocker assembly and the side door fixing seat by detecting the position of the door knocker assembly, thereby alerting the control room of the opening and closing status of the door knocker assembly.

[0016] By adopting the above technical solution, the position of the door ring assembly is detected by the sensing connection assembly to determine the connection status of the door ring assembly and the side door fixing seat, thereby alerting the control room of the opening and closing status of the door ring assembly.

[0017] Preferably, a "U"-shaped hole is provided on the positioning plate, and the positioning plate is connected to the door knocker assembly via the "U"-shaped hole. The "U"-shaped hole facilitates adjustment of the connection position between the positioning plate and the door knocker assembly, thereby adjusting the distance between the positioning plate and the proximity switch.

[0018] By adopting the above technical solution, the positioning plate adjusts its connection position with the door ring assembly through the "U"-shaped hole, thereby adjusting the distance between the positioning plate and the proximity switch. The "U"-shaped hole increases the convenience of adjusting the positioning plate.

[0019] Preferably, the door ring assembly is provided with a plug-in shaft, and the side door fixing seat is provided with a plug-in point, the plug-in point cooperates with the plug-in shaft, and the plug-in shaft fastens and limits the connection between the door ring assembly and the side door fixing seat by cooperating with the plug-in point.

[0020] By adopting the above technical solution, the tightness of the connection between the door ring assembly and the side door fixing seat is improved by arranging the plug-in axis and the plug-in point on the door ring assembly and the side door fixing seat, and the relative position of the door ring assembly and the side door fixing seat is limited.

[0021] Preferably, at least two plugging points for the plug-in shaft to be inserted and connected may be provided on the side door fixing seat, and the two plug-in points respectively correspond to the two positions of the plug-in shaft in the opening and closing states of the door ring assembly.

[0022] By adopting the above technical solution, the two plugging and unplugging points correspond to the two positions of the plugging and unplugging shaft in the opening and closing states of the door ring assembly. The plugging and unplugging shaft and the plugging and unplugging points are located to maintain the open state of the door ring assembly, which is convenient for people to get off or get on the vehicle, and also convenient to maintain the closed state of the door ring assembly to prevent people from stepping out of the door while the vehicle is driving.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. A limit assembly is provided between the door ring assembly and the side door fixing seat, which limits the position of the door ring assembly by limiting the connection position between the door ring assembly and the side door fixing seat, and provides the door ring assembly with more supporting force through the limit assembly to improve the stress condition of the connection position between the door ring assembly and the side door fixing seat. On the one hand, more supporting force enables the door ring assembly to be stably parallel to the horizontal ground when closed, thereby blocking personnel and preventing the door ring assembly from being perpendicular to the horizontal ground due to aging after long-term use, thereby increasing the safety of the door locking mechanism. On the other hand, by providing more supporting force at the connection between the door ring assembly and the side door fixing seat, the door ring assembly and the side door fixing seat are more solid, thereby preventing deformation of the connection, thereby extending the service life of the door locking mechanism. In specific implementation, during the process of rotational connection between the door ring assembly and the side door fixing seat, the first semi-axis and the second semi-axis will be blocked by each other, and the side wall of the first semi-axis and the side wall of the second semi-axis will fit together, so that the rotation process space is limited and cannot continue to rotate;

[0025] 2. The door knocker assembly is rotated on the side door fixing seat so that the door knocker assembly is located at different positions, thereby making the door knocker assembly have two states: blocking personnel and not blocking personnel. When the door knocker assembly is vertical to the ground, the strength of the door knocker assembly in blocking personnel reaches the best. When the door knocker assembly tilts to the right at a certain angle, the door knocker assembly will not fall down by itself;

[0026] 3. The position of the door ring assembly is detected by the sensing connection assembly to determine the connection status of the door ring assembly and the side door fixing seat, thereby alerting the control room of the opening and closing status of the door ring assembly.
