Description

Technical Field

[0001] This utility model relates to the field of passenger door technology, specifically a passenger door assembly with an anti-pinch device. Background Technology

[0002] Passenger exit doors on passenger buses are usually double-opening to increase the opening area and facilitate passenger disembarkation. The driver can observe the passengers disembarking by watching the monitor inside the vehicle and then control the opening and closing of the passenger exit doors with one button on the vehicle's main control panel.

[0003] Since the opening and closing of the passenger exit doors in a car is controlled by the driver, who is often far from the exit door and can only watch the passengers getting off through the monitor, when there are many people in the car, the driver may close the passenger exit door at an inappropriate time due to the chaotic monitoring image. This may cause some passengers to fail to get off in time, or even be injured by the door closing while they are getting off. This has been a frequent occurrence in the news in recent years. Therefore, a passenger door with an anti-pinch device is needed to solve this problem. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes a passenger door assembly with an anti-pinch device, which enables the passenger door to have an anti-pinch function. When a passenger is between two passenger doors, the door will not close with a large force, so that the passenger will not be subjected to a large squeezing force when he / she is trapped by the door, thereby avoiding the passenger being injured because the passenger door is closed.

[0005] The technical solution to achieve the purpose of this utility model is as follows: a passenger door assembly with an anti-pinch device, including a housing, an anti-pinch door assembly at the bottom of the housing, the anti-pinch door assembly including a first pivot, a first rotating door, a hinge, and a second rotating door, two first pivots rotatably connected to both ends of the housing, two first rotating doors fixedly connected to the two first pivots, two hinges respectively disposed on the two first rotating doors, and two second rotating doors hinged to the two first rotating doors respectively via the two hinges, a drive assembly disposed on the housing, the drive assembly including a motor, a sliding seat, an elastic block, a second pivot, and a spring, the motor fixedly connected to the housing, two sliding seats slidably connected to the bottom of the housing, two elastic blocks slidably connected to the interior of the two sliding seats, two second pivots rotatably connected to the two elastic blocks, two second pivots fixedly connected to the two second rotating doors, and two springs fixedly connected between the inner walls of the two sliding seats and the two elastic blocks.

[0006] Preferably, the drive assembly further includes a bidirectional screw and two sliders. The bidirectional screw is rotatably connected to the inner wall of the chassis, and the two sliders are slidably connected to the inside of the chassis. The two sliders are threadedly connected to the bidirectional screw, and the two sliders are respectively fixedly connected to two sliding seats.

[0007] Preferably, the drive assembly further includes a worm gear and a worm, the worm gear being fixedly connected to a bidirectional screw, and the worm being fixedly connected to the output shaft of the motor, with the worm gear meshing with the worm.

[0008] Preferably, the drive assembly further includes magnetic sheets, with two magnetic sheets fixedly connected to each of the two second rotating doors, and the two sets of magnetic sheets are arranged symmetrically.

[0009] Preferably, the two ends of the bidirectional screw are provided with threads in opposite directions, and the two sliders are respectively connected to two sets of threads in opposite directions.

[0010] Preferably, the surface of the magnetic sheet is arc-shaped, and the two sets of magnetic sheets are located at the top and bottom of the second rotating door, respectively.

[0011] Compared with the prior art, the significant advantages of this utility model are:

[0012] In this invention, when the passenger door closes and the passenger fails to disembark in time, the second rotating door will trap the passenger. At this time, although the motor still controls the movement of the slider and the sliding seat, the spring located in the sliding seat can be compressed, so that the second rotating door will not close completely and injure the passenger. At this time, the force on the trapped passenger is only the elastic force of the spring when it is compressed. Therefore, although the passenger is trapped, he will not be injured. When the passenger breaks free from the second rotating door, the elastic force of the spring will cause the two second rotating doors to close together. When the two second rotating doors close together, the two sets of magnetic plates on them will attract each other. The magnetic attraction will make the two second rotating doors tightly fasten together, thus making the door tightly closed and difficult to open under external force. Attached Figure Description

[0020] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0021] This utility model provides an improved passenger door assembly with an anti-pinch device. The technical solution of this utility model is as follows:

[0022] like Figures 1-4As shown, a passenger door assembly with an anti-pinch device includes a housing 1. An anti-pinch door assembly 2 is located at the bottom of the housing 1. The anti-pinch door assembly 2 includes a first pivot 21, a first rotating door 22, a hinge 23, and a second rotating door 24. Two first pivots 21 are rotatably connected to both ends of the housing 1. Two first rotating doors 22 are fixedly connected to the two first pivots 21. Two hinges 23 are respectively mounted on the two first rotating doors 22. Two second rotating doors 24 are hinged to the two first rotating doors 22 via the two hinges 23. When the door is opened, the first rotating doors 22 and the second rotating doors 24 fold inwards towards the inside of the vehicle. Therefore, when the two second rotating doors 24 are closed, pushing outwards from inside the vehicle will not open the door. A drive assembly 3 is located on the housing 1. The drive assembly 3 includes a motor 31, a sliding seat 34, an elastic block 35, a second pivot 36, and a spring 37. The motor 31 is fixedly connected to... The two sliding seats 34 are slidably connected to the bottom of the chassis 1, and the two elastic blocks 35 are slidably connected to the inside of the two sliding seats 34 respectively. The two second rotating shafts 36 are rotatably connected to the two elastic blocks 35 respectively. The two second rotating shafts 36 are fixedly connected to the two second rotating doors 24 respectively. The two springs 37 are fixedly connected between the inner walls of the two sliding seats 34 and the two elastic blocks 35 respectively. The movement of the slider 33 will drive the sliding seats 34 and the second rotating shafts 36 to move, so as to control the relative movement between the second rotating door 24 and the first rotating door 22, so as to complete the opening and closing of the entire door. If the driver controls the motor 31 to start and close the door, and a passenger is trapped between the second rotating doors 24, the springs 37 can be compressed, so that the two second rotating doors 24 that would normally close will not close. Even if the passenger is trapped, he will only receive a clamping force equal to the elastic force of the springs 37, so he is not easily injured.

[0023] In this embodiment, the drive assembly 3 also includes a bidirectional screw 32 and two sliders 33. The bidirectional screw 32 is rotatably connected to the inner wall of the housing 1, and the two sliders 33 are slidably connected to the inside of the housing 1. The two sliders 33 are threadedly connected to the bidirectional screw 32, and the two sliders 33 are fixedly connected to the two sliding seats 34 respectively. The bidirectional screw 32 is driven to rotate by the motor 31, which in turn causes the sliders 33 and sliding seats 34 to move. This process is completely controlled by the motor 31. Although the opening and closing of the second rotating door 24 is controlled by the movement of the sliding seats 34, a spring 37 and an elastic block 35 are provided between the sliding seats 34 and the second rotating door 24. Therefore, even if the second rotating door 24 is closed under the control of the motor 31, if a passenger is trapped, the two second rotating doors 24 can compress the spring 37, thereby leaving a safe distance and preventing the passenger from being injured when the second rotating door 24 is forcibly closed.

[0024] In this embodiment, the drive assembly 3 further includes a worm gear 321 and a worm 322. The worm gear 321 is fixedly connected to the bidirectional screw 32, and the worm 322 is fixedly connected to the output shaft of the motor 31. The worm gear 321 and the worm 322 mesh with each other.

[0025] In this embodiment, the drive assembly 3 also includes magnetic sheets 38. Two magnetic sheets 38 are fixedly connected to each of the two second rotating doors 24. The two sets of magnetic sheets 38 are symmetrically arranged. By using the mutual attraction of the magnetic sheets 38, the two second rotating doors 24 can generate a sufficiently large attraction force between them when they are closed, so that the second rotating doors 24 are not prone to gaps when subjected to external forces.

[0026] In this embodiment, the two ends of the bidirectional screw 32 are provided with threads in opposite directions, and the two sliders 33 are respectively connected to two sets of threads in opposite directions.

[0027] In this embodiment, the surface of the magnetic sheet 38 is an arc surface. The two sets of magnetic sheets 38 are located at the top and bottom of the second rotating door 24, respectively. Since the second rotating door 24 needs to rotate around the hinge 23 when it is opened, the surfaces of the two sets of magnetic sheets 38 are arc surfaces, so that the two sets of magnetic sheets 38 will not collide with each other when the second rotating door 24 is opened and closed.

[0028] The specific working method is as follows: When controlling the opening and closing of the passenger door, the motor 31 can be started. The motor 31 will drive the worm gear 322 to rotate. The rotation of the worm gear 322 will drive the worm wheel 321 and the double-headed screw 32 to rotate. When the double-headed screw 32 rotates, it will drive the slider 33 to move in different directions in the housing 1. The movement of the slider 33 will drive the sliding seat 34 to move. When the sliding seat 34 moves, the spring 37 inside it will drive the elastic block 35 to move through the elastic force. The movement of the elastic block 35 will cause the second rotating shaft 36 to move accordingly, driving the second rotating door 24 to rotate around the hinge 23. Therefore, at this time, the second rotating door 24 will fold or unfold together with the first rotating door 22, thereby controlling the opening and closing of the entire passenger door.

[0029] When the passenger door closes and the passenger fails to disembark in time, the second rotating door 24 will trap the passenger. At this time, although the motor 31 still controls the movement of the slider 33 and the sliding seat 34, the spring 37 located in the sliding seat 34 can be compressed at this time, so that the second rotating door 24 will not be completely closed to prevent injury to the passenger. At this time, the force on the trapped passenger is only the elastic force of the spring 37 when it is compressed. Therefore, although trapped, the passenger will not be injured. When the passenger breaks free from the second rotating door 24, the elastic force of the spring 37 will cause the two second rotating doors 24 to close together. When the two second rotating doors 24 are closed together, the two sets of magnetic plates 38 on them will attract each other. The magnetic attraction will make the two second rotating doors 24 tightly fastened together, thus making the door tightly closed and difficult to open under external force.
