Description

Technical Field

[0001] The present application relates to the field of rail transit technology, and in particular to a sensitive trigger structure and a trigger method for a vehicle door. Background Art

[0002] Rail vehicles include high-speed trains, EMUs and subways. The doors of this type of vehicle are designed to be single-open or double-open doors with higher weight to meet the requirements of safety and reliability. Therefore, a power source with stronger traction is provided for opening and closing the doors. The problem brought about by this is that during the process of opening and closing the doors, especially during the process of closing the doors, a relatively large force is applied to the doors. If the passengers have not completed the action of getting on or off the vehicle, or if the passengers' belongings or even their bodies are still in the process of the door closing, a more serious safety problem will arise.

[0003] At present, the existing sensitive triggering methods of rail vehicle door systems are mainly patented - 202311569338.4 - for obstacle detection door systems for rail vehicles: when the door is closed and encounters squeezing and dragging (squeezing and dragging on both sides), it will trigger the electronic components to detect the pressure and transmit the signal to the cab control center system. The sensitive components can be easily triggered inside and outside the vehicle, causing the door to be frequently reopened and the train to leave late without affecting the safety of passengers after normal closure. Since there is no safety risk when triggered inside the vehicle, if the vehicle is also easily triggered, the reliability of vehicle operation will be reduced. Summary of the invention

[0004] The purpose of the present application is to provide a sensitive trigger structure and trigger method for a vehicle door, so as to solve the defects in the prior art that the vehicle door system is prone to frequent reopening of the vehicle door even when it is not necessary and the vehicle door system has low reliability.

[0005] In order to achieve the above objectives, this application is implemented by adopting the following technical solutions: On the one hand, the present application discloses a sensitive trigger structure for a vehicle door, which includes a first fixing member and a second fixing member arranged relatively to each other, and electronic components are obliquely installed on the first fixing member and / or the second fixing member, and a first rubber strip and a second rubber strip are correspondingly provided on the opposite surfaces of the first fixing member and the second fixing member, and the first rubber strip and the second rubber strip are subjected to forces that match each other, and the first rubber strip or the second rubber strip adjacent to the electronic component is deformed under unidirectional force so that the electronic component is activated under pressure.

[0006] According to a further solution of the present application, first mounting grooves are provided on opposite surfaces of the first fixing member and the second fixing member, and flange mounting bodies are correspondingly provided on the first rubber strip and the second rubber strip, and the flange mounting bodies are correspondingly placed in the first mounting grooves.

[0007] In a further solution of the present application, a second mounting groove is provided on the opposite surface of the first fixing member and / or the second fixing member; A second mounting groove is provided on the first fixing member or the second fixing member, and the electronic component is fixed obliquely in the second mounting groove; The first fixing member and the second fixing member are provided with a second mounting groove, the two second mounting grooves are symmetrically arranged, and the two electronic components are tiltedly fixed in the second mounting grooves in a one-to-one correspondence.

[0008] In a further solution, a triggering member is obliquely provided on the first rubber strip or the second rubber strip close to the electronic component, and one end of the triggering member contacts the electronic component.

[0009] In a further solution, a first trigger member and a second trigger member are correspondingly inclinedly provided on the contact surface of the first rubber strip or the second rubber strip, a first guide edge is provided on the first trigger member close to the second rubber strip, a matching second guide edge is correspondingly provided on the second trigger member, and the first guide edge and the second guide edge are intermittently matched.

[0010] In a further solution, a first sealing lip is provided on the first guide edge, and a second sealing lip is provided on the second guide edge.

[0011] A further solution of the present application also includes a control center, and the electronic component signal is connected to the control center.

[0012] According to a further solution of the present application, a cavity is provided in the first rubber strip or the second rubber strip.

[0013] On the other hand, a triggering method based on the above-mentioned sensitive triggering structure for a vehicle door comprises the following steps: Set the safety pressure of electronic components to a safe value; The first fixing member and the second fixing member are started to move relative to each other until the first rubber strip and the second rubber strip are matched, an object is clamped between the first rubber strip and the second rubber strip, and the clamped object is pulled so that the electronic component is compressed or not compressed. When the electronic component is not compressed, the pulling direction of the clamped object is a safe direction; The pressure value of the electronic component is greater than the safety value, and the first fixing member and the second fixing member move away from each other in back-to-back directions.

[0014] A further solution of the present application includes that the pulling direction of the clamped object is a first direction and a second direction; If the clamped object is pulled in the first direction, the electronic component is pressed to start the transmission of a signal to the control center, and the control center issues a movement instruction for the first fixing member and the second fixing member to move away from each other, and the second direction is a safe zone; If the clamped object is pulled in the second direction, the electronic component is pressed to start transmitting a signal to the control center, and the control center issues a movement instruction for the first fixing member and the second fixing member to move away from each other, and the first direction is a safe area.

[0015] The beneficial effects of this application are: Two groups of rubber strips are designed in this structure and are installed on corresponding fixings (door leaves) respectively. Electronic components are arranged on one fixing or two fixings. When the two fixings drive the two groups of rubber strips to match, the rubber strips are deformed by force and trigger the electronic components. When the force value of the electronic components reaches a safe value, the two fixings move away from each other, and the opposite direction of the force deformation of the rubber strips is the safe zone. The electronic components are designed to be selectively triggered, which reduces the frequent reopening of the door under unnecessary circumstances and ensures the reliability of the door system.

[0016] The two sets of rubber strips and the first and second rubber strips have matching first and second sealing lips fixed on their opposite surfaces, which can greatly increase the overlap of the two sets of rubber strips, detect smaller obstacles, and ensure the safety of passengers.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Embodiment 1

[0020] like Figure 1 As shown, the present embodiment discloses a sensitive trigger structure for a vehicle door, which includes a first fixing member 1 and a second fixing member 5. Usually, a first door leaf is selected to replace the first fixing member 1 and a second door leaf is selected to replace the second fixing member 5. A first rubber strip 3 is fixed to one side of the first fixing member 1, and a second rubber strip 4 is fixed to one side of the second fixing member 5. The first rubber strip 3 and the second rubber strip 4 are arranged opposite to each other. The first rubber strip 3 and the second rubber strip 4 can be closed under the driving of an external force. An electronic component 2 is arranged between the first fixing member 1 and the first rubber strip 3. The electronic component is obliquely fixed on the first fixing member 1. When in use, the first fixing member 1 and the second fixing member 5 are close to each other, so that the first rubber strip 3 and the second rubber strip 4 can be closed. If there is a clamped object between the first rubber strip 3 and the second rubber strip 4, when the clamped object is pulled to the left, the new deformation of the first rubber strip 3 will trigger the electronic component 2 to start. At this time, the electronic component 2 is electrically connected to the control center of the cab, and the control center issues a door opening instruction. When the clamped object is pulled to the right, the deformation of the first rubber strip 3 will not trigger the electronic component 2.

[0021] Reference 1 to Figure 3 In this embodiment, the electronic component 2, the first rubber strip 3 and the second rubber strip 4 are all detachably installed. Usually, a second installation groove is opened on the first fixing member 1, and the electronic component 2 is tilted and fixed in the second installation groove; a pair of first installation grooves are opened near the edges of the opposite surfaces of the first fixing member 1 and the second fixing member 5, and the first rubber strip 3 is correspondingly provided with a first flange 3-1 and a second flange 3-2, and the second rubber strip 4 is correspondingly provided with a third flange 4-1 and a fourth flange 4-2, and the first flange 3-1 and the second flange 3-2, the third flange 4-1 and the fourth flange 4-2 are embedded in the corresponding first installation grooves.

[0022] In other embodiments, electronic components 2 are arranged on the first fixing member 1 and the second fixing member 5. In this case, first mounting grooves are opened on the opposite surfaces of the first fixing member 1 and the second fixing member 5. It should be noted here that the two second mounting grooves need to be symmetrically arranged, and the two electronic components 2 are tilted and fixed in the second mounting grooves one by one. After the first rubber strip 3 and the second rubber strip 4 are matched, if an object is clamped, the installation positions of the two electronic components 2 need to ensure that when the clamped object is pulled in the same direction, the two electronic components 2 are triggered; when the other side is pulled, the two electronic components 2 are not triggered.

[0023] Reference Figure 2 and Figure 3 In this embodiment, a first trigger member is obliquely arranged on the first rubber strip 3, and a second trigger member is obliquely arranged on the second rubber strip 4, wherein a first protrusion 3-3 is arranged at one end of the first trigger member close to the electronic component 2, and the first protrusion 3-3 is arranged in contact with or close to the electronic component 2, and a second protrusion 3-4 is arranged at one end of the first trigger member close to the second rubber strip 4, and the second protrusion 3-4 and the first protrusion 3-3 are inclined; similarly, a third protrusion 4-3 and a fourth protrusion 4-4 are arranged on the second trigger member; the third protrusion 4-3 is symmetrically arranged with the first protrusion 3-3, and the fourth protrusion 4-4 is symmetrically arranged with the second protrusion 3-4, a first oblique edge is arranged on the second protrusion 3-4, and a second oblique edge is arranged on the fourth protrusion 4-4, and the inclinations of the two oblique edges match.

[0024] In this embodiment, the electronic component 2 is only arranged on the first fixing member 1, and various protrusions are symmetrically arranged on the second rubber strip 4 and the first rubber strip 3, so as to improve the sealing degree when the two rubber strips are in contact and improve the detection accuracy of obstacles.

[0025] In this embodiment, a first sealing lip 3-5 is provided on the second protrusion 3-4, and a second sealing lip 4-5 is provided on the fourth protrusion 4-4. The setting of the first sealing lip 3-5 and the second sealing lip 4-5 ensures that there is a large overlap between the two rubber strips after installation, ensuring that even small obstacles can be detected, thereby improving the detection accuracy of the device; in addition, in order to make the deformation of the rubber strips more obvious or easier, a cavity is set inside the first rubber strip 3 and the second rubber strip 4 when they are manufactured. Embodiment 2

[0026] This embodiment provides a security system, which includes the sensitive trigger structure in the above-mentioned embodiment 1. Embodiment 3

[0027] Reference Figure 4 and Figure 5 In this embodiment, a triggering method is provided, which includes the following steps: Before installing the electronic component 2, set the safety value of the pressure on the electronic component 2. During the door closing process, if an obstacle squeezes or drags the door, the second protrusion 3-4 of the first rubber strip 3 is deformed in the first direction by force. The dragging squeezes the first protrusion 3-3 in the second direction, which is equivalent to causing the second protrusion 3-4 to press the electronic component 2 (see Figure 5 ), the electronic component 2 detects the pressure and transmits the signal to the cab control center, which determines whether the door needs to be opened. If the detection force is higher than the set safety value, it will not affect the normal safe driving of the train and will not trigger the door opening, thus ensuring the safe driving of the train while ensuring safety; When the second protrusion 3-4 is dragged and squeezed in the second direction, the first protrusion 3-3 is squeezed in the first direction, and the electronic components will not be triggered (see Figure 4 ), can effectively identify whether to stop the car to reduce dangerous situations, avoid unnecessary triggering actions, reduce frequent reopening of doors after normal closure, delayed departure of trains, etc.; At the same time, after the door is closed, the corresponding first sealing lip 3-5 and second sealing lip 4-5 on the rubber strip have a certain overlap, so the sealing performance is better. Figure 1 When the rubber strips 1 and 2 are installed, there is a large overlap between the two rubber strips, ensuring that even small obstacles can be detected.

[0028] Because the device has electronic components 2 installed on only one side, it will be triggered when and only when the first rubber strip 3 is squeezed and dragged in the first direction. This can prevent people who are on the platform where the rail vehicle is passing and are clamped (by clothes, bag straps, etc.) due to the closed door from being pulled by the vehicle. When the first rubber strip 3 is tilted in the second direction, the electronic components 2 will not be triggered, thereby reducing the probability of vehicle failure triggering and avoiding unnecessary parking.
