Description

Technical Field

[0001] This utility model relates to the field of anti-pinch technology for vehicle doors, specifically a vehicle door for transportation equipment with an anti-pinch structure. Background Technology

[0002] As an important part of urban public transportation, the safety and reliability of the subway are of paramount importance. The door system, as an important part of the subway vehicle, is particularly critical in its safety design. Among them, the anti-pinch protection function is an important aspect of the door system design, which can effectively prevent passengers from being pinched during the closing process of the doors. If a subway car door pinches a passenger, luggage, or other obstacle during the closing process, it may cause injury to the passenger or damage to the equipment. Traditional anti-pinch protection functions are mostly implemented through infrared sensor anti-pinch technology. However, infrared sensors have limited detection distance and are easily affected by environmental interference. When encountering relatively soft or irregular objects (such as bags or fabrics), the detection sensitivity is insufficient, causing the anti-pinch function to fail to activate. Utility Model Content

[0003] The purpose of this utility model is to provide a transportation equipment door with an anti-pinch structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A transportation equipment door with an anti-pinch structure includes a left door panel and a right door panel, and further includes: Mounting slot one is located on the end side of the left door panel; Mounting slot two is located on the end side of the right door panel; A movable seat is set in the mounting slot 1. Several sliding slots are equally spaced on the outer side wall of the movable seat. Contact pieces 1 are fixedly connected in each of the sliding slots. The inner side wall of the movable seat is connected to the left door panel by two electric telescopic rods. A fixing seat is fixed inside the mounting groove 2. The outer side wall of the fixing seat is provided with a number of docking grooves at equal intervals. Contact pieces 2 are fixedly connected inside the number of docking grooves. Several protruding pillars are provided, each slidably connected inside several sliding slots. The inner and outer walls of the protruding pillars are respectively provided with contact head one and contact head two. A spring is fixedly connected between the inner wall of the protruding pillar and the sliding slot.

[0005] Furthermore, the two opposite side walls of the movable seat are provided with strip grooves.

[0006] Furthermore, a cleaning component is provided inside the strip groove. The cleaning component includes two movable blocks, which are slidably connected to the two strip grooves respectively. The two movable blocks are fixed to a fixing plate by two connecting rods. A sponge is fixedly connected to the inner side wall of the fixing plate, and the sponge is used to wipe the protruding post.

[0007] Furthermore, the top and bottom of the movable seat are provided with cavities, and a dual-axis motor is installed in each of the two cavities. The two motor shafts of the dual-axis motor drive take-up rollers, and traction ropes are wound on the two take-up rollers. The two traction ropes are respectively fixed through the two movable blocks.

[0008] Furthermore, the outer wall of the protruding post is symmetrically and fixedly connected with two sliders.

[0009] Furthermore, the outer wall of the protruding post is provided with a flexible pad.

[0010] Furthermore, the dimensions of the mating groove are larger than the dimensions of the protrusion.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By setting a movable seat and a protruding post on the left door panel, and a fixed seat that cooperates with the movable seat on the right door panel, when there is no obstacle when closing the door, the protruding post can naturally insert into the docking groove, and the second contact head will naturally contact the second contact piece, thus closing the door normally. When there is an obstacle when closing the door, the protruding post will be squeezed when it contacts the obstacle first, and will retract into the sliding slot, so that the first contact head contacts the first contact piece, thereby triggering the anti-pinch system. This mechanical structure realizes the triggering of the anti-pinch function, improves the reliability and anti-interference ability of the anti-pinch structure, ensures the contact stability during the normal closing process, and can quickly trigger the anti-pinch mechanism when encountering an obstacle.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example Please see Figure 1-7In this embodiment of the present invention, a transportation equipment door with an anti-pinch structure includes a left door panel 100, a right door panel 200, a movable seat 300, a fixed seat 400, and a protruding post 500. The left door panel 100 has a mounting groove 110 on its end facing the right door panel 200, and the right door panel 200 has a mounting groove 210 on its end facing the left door panel 100. The movable seat 300 is slidably disposed inside the mounting groove 110. At least two electric telescopic rods 350 are installed and fixed inside the left door panel 100. The output ends of both electric telescopic rods 350 are fixedly connected to the inner wall of the movable seat 300. The movable base 300 can extend out of the mounting slot 110. The outer wall of the movable base 300 has several sliding slots 310 evenly spaced, and each sliding slot 310 has a contact piece 320 fixedly connected inside. The inner wall of the movable base 300 is connected to the left door panel 100 via two electric telescopic rods 350. A fixed base 400 is fixedly connected inside the mounting slot 210. The outer wall of the fixed base 400 has several mating slots 410 evenly spaced, the positions of which correspond to the positions of the sliding slots 310. Each mating slot 410 has a contact piece 420 fixedly connected inside. Several sliding slots 310 each have a slidably connected protrusion 500. The inner and outer walls of each protrusion 500 are respectively provided with a first contact head 510 and a second contact head 520. The first contact head 510 is used to connect with a first contact piece 320, and the second contact head 520 is used to connect with a second contact piece 420. A spring 530 is fixedly connected between the inner wall of the protrusion 500 and the sliding slot 310. Two sliders 540 are symmetrically fixedly connected to the outer wall of the protrusion 500. The sliding slot 310 has a groove for the sliders 540 to slide, so that under the elastic action of the spring 530, the protrusion 500 defaults to protruding outward from the sliding slot 310. The outer wall of 500 is provided with a flexible pad, and the outer walls of the movable seat 300 and the fixed seat 400 are also provided with buffer pads to reduce the impact and noise when the door is closed, while improving passenger comfort. The size of the docking groove 410 is larger than the size of the protrusion 500, so that the protrusion 500 can smoothly enter the docking groove 410 when the door is closed. Both the movable seat 300 and the fixed seat 400 are made of high-strength, wear-resistant materials to ensure stability during frequent door opening and closing. The first contact head 510 and the second contact head 520 are made of conductive materials or materials with signal transmission functions to transmit trigger signals to the door control system.

[0016] Specifically, when the left door panel 100 and the right door panel 200 are in the open state, the two electric telescopic rods 350 extend, causing the movable seat 300 to extend outward along the mounting groove 110, protruding from the end side of the left door panel 100. The protruding post 500 on the movable seat 300, under the action of the spring 530, defaults to protruding from the surface of the movable seat 300, preparing for contact when the door closes, ready to mate with the docking groove 410 on the fixed seat 400. When the subway door control system issues a closing command, the door begins to close. As the door closes, the left door panel 100... As the right door panel 200 gradually approaches, when the movable seat 300 and the fixed seat 400 get close enough, the protruding post 500 protruding from the surface of the movable seat 300 will naturally embed into the docking groove 410 on the fixed seat 400. At this time, the contact head 520 at the outer end of several protruding posts 500 will contact the contact piece 420 in several docking grooves 410 respectively. At this time, the control system recognizes that it is a normal contact during the closing process, does not trigger the anti-pinch mechanism, and controls the two electric telescopic rods 350 to retract until the left door panel 100 and the right door panel 200 are closed. If an obstacle (such as a person or bag) is encountered during the closing process, the protruding post 500 will first contact the obstacle. Because the protruding post 500 is connected to the spring 530, it has elasticity and restoring force. When it contacts the obstacle, the protruding post 500 will retract into the sliding slot 310. As the protruding post 500 retracts, the contact head 510 on the inner side wall of the protruding post 500 will contact the contact piece 320 in the sliding slot 310. This contact action will trigger the anti-pinch mechanism, generating a mechanical or electrical signal. The triggered anti-pinch mechanism signal will be transmitted to the subway door control system. After receiving the signal, the door control system will immediately issue a command to stop the door from closing, so as to avoid or reduce the clamping of the obstacle. When the obstacle is removed, the protruding post 500 will return to its initial state under the action of the spring 530, protruding from the surface of the moving seat 300, ready for the next closing.

[0017] like Figure 4-6As shown, in this embodiment, the two opposite sidewalls of the movable seat 300 are provided with strip grooves 340. A cleaning component 600 is disposed in the strip groove 340. The cleaning component 600 includes two movable blocks 610, which are slidably connected to the two strip grooves 340 respectively. A connecting rod 620 is fixedly connected to the front sidewall of each of the two movable blocks 610. A fixing plate 630 is fixedly connected between the ends of the two connecting rods 620. A sponge 640 is fixedly connected to the inner sidewall of the fixing plate 630 facing the protrusion 500. The surface of 640 corresponds to the position of the protrusion 500 and is used to wipe the protrusion 500. The top and bottom of the movable seat 300 are provided with cavities 330. A dual-axis motor 700 is installed in each of the two cavities 330. The two motor shafts of the dual-axis motor 700 drive the take-up rollers 710. A traction rope 720 is wound on each of the two take-up rollers 710. The two traction ropes 720 are respectively fixed through the two movable blocks 610, and the other ends of the two traction ropes 720 are respectively wound on the two take-up rollers 710 located in the lower cavity 330.

[0018] In this embodiment, during the subway's operation and repeated opening and closing of the doors, dust will always accumulate on the protruding post 500 protruding from the surface of the moving seat 300. The cleaning component 600 can be periodically controlled to wipe and clean the protruding post 500. This causes the two dual-axis motors 700 to drive in opposite directions, so that the upper and lower winding rollers 710 and the lower winding roller 710 alternately wind up and unwind. This causes the traction rope 720 to pull the moving block 610, which moves up and down along the strip groove 340, allowing the sponge 640 to gently wipe the surface of the protruding post 500.

[0019] In this invention, the door control system is existing technology and will not be described in detail here.
