Description

Technical Field

[0001] This utility model relates to the field of pneumatic car door technology, and more specifically, to a pneumatic sliding car door device with buffer and anti-pinch function. Background Technology

[0002] Pneumatic doors are a type of door control system that uses compressed air as a power source. Compressed air is generated by a compressor, and after passing through an air source treatment unit (filtering and pressure reduction), the airflow direction is controlled by a solenoid valve. When air enters through port A, the piston pushes the door to open; when air enters through port B, it closes in the opposite direction. The speed is adjusted by a one-way speed control valve. It is widely used in buses, subway trains, and industrial equipment.

[0003] Existing pneumatic car doors sometimes fail to stop closing in time due to unexpected factors (such as insufficient sensor signal transmission or aging of mechanical parts), causing people to be trapped and injured during the closing process. Therefore, to address this problem, we propose a pneumatic sliding car door device with a buffer and anti-pinch function. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pneumatic sliding door device with buffer and anti-pinch function. By utilizing the rubber layer and rubber hose to make contact with the human body first, the clamping strength is reduced, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic sliding door device with buffer and anti-pinch function, comprising a main component including a pneumatic door, a rubber layer bonded to one side of the pneumatic door, a rubber hose bonded to one side of the rubber layer, a trigger rod slidably connected to the inner side of the pneumatic door, a toothed rod fixedly installed at one end of the trigger rod, a cross column fixedly installed on the inner side of the pneumatic door, a gear rotatably connected to the outer side of the cross column, the gear and the toothed rod being meshed, a circular toothed rod meshing on the outer side of the gear, and a fixing plate fixedly installed at one end of the circular toothed rod.

[0006] In a preferred embodiment, the rubber layer and the rubber hose are made of a malleable material, and the number of the rubber layer and the rubber hose is set to a plurality, which are arranged in a linear filling pattern about one side of the pneumatic door.

[0007] In a preferred embodiment, the number of racks and gears is set to multiple, and the multiple racks and gears are arranged in a mirror-symmetrical manner about the transverse centerline of the pneumatic door.

[0008] In a preferred embodiment, the fixed plate is slidably connected to the inner side of the pneumatic door, the circular toothed rod and the rubber hose are arranged in a one-to-one correspondence, one end of the toothed rod is sleeved with a spring, and the spring is fixedly installed on the inner side of the pneumatic door.

[0009] In a preferred embodiment, the stop component includes a housing, which is fixedly installed on one side of the pneumatic door. A sensor is fixedly installed on the inner side of the housing, and the sensor is arranged in the same vertical plane as the rubber hose. A cylinder is fixedly installed on the inner side of the housing.

[0010] In a preferred embodiment, one end of the cylinder is threadedly connected to a push rod, one end of the push rod is provided with a pawl, a positioning rod is hinged to the inner side of the pawl, the positioning rod is fixedly installed on the inner side of the housing, and a ratchet is rotatably connected to the inner side of the housing. The ratchet passes through one side of the pneumatic valve and is integrally set with the gear.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] This invention incorporates a rubber layer and a rubber hose. When the pneumatic door closes, if a person is at the doorway, the rubber layer and hose first contact the person, reducing the clamping strength and lowering the risk of injury. At this point, the sensor detects the contact and sends a command, which then pulls the push rod, causing it to deflect. This engages the pawl and ratchet, preventing the ratchet from rotating and preventing the circular toothed rod from being inserted into the rubber hose. This provides double protection for personnel and enhances safety.

[0013] This invention incorporates a pawl. When a person comes into contact with the rubber layer and the rubber hose, the sensor detects this and sends a command to the cylinder. The cylinder then pulls the push rod, causing it to deflect. This engages the pawl with the ratchet, preventing the ratchet from rotating and preventing the circular toothed rod from being inserted into the rubber hose, thus preventing injury to the person.

Detailed Implementation

[0018] 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.

[0019] Example 1: Refer to the appendix of the instruction manual. Figure 1-2 A pneumatic sliding door device with buffer and anti-pinch function includes a main component 100, comprising a pneumatic door 101. A rubber layer 102 is adhered to one side of the pneumatic door 101, and a rubber hose 103 is adhered to one side of the rubber layer 102. The rubber layer 102 and rubber hose 103 are positioned on one side of the pneumatic door 101 to provide a larger buffer space, preventing injury to people when the pneumatic door 101 closes. A trigger rod 104 is slidably connected to the inner side of the pneumatic door 101, and a toothed rod 105 is fixedly installed at one end of the trigger rod 104. A crossbar 106 is fixedly installed to the inner side of the pneumatic door 101, and a rotatable link is connected to the outer side of the crossbar 106. Gear 107 is meshed with rack 105. A circular rack 108 meshes with the outer side of gear 107. A fixing plate 109 is fixedly installed at one end of the circular rack 108. When the pneumatic door 101 moves to close, the trigger rod 104 contacts the door frame and slides into the inside of the pneumatic door 101. At the same time, rack 105 meshes with gear 107, driving gear 107 to rotate, so that the circular rack 108 slides into the rubber hose 103. When the pneumatic door 101 closes with the door frame, the circular rack 108 is fully inserted into the inside of the rubber hose 103 for support, thereby preventing the rubber layer 102 and the rubber hose 103 from being dented and deformed.

[0020] The rubber layer 102 and rubber hose 103 are made of malleable material. Through the arrangement of the rubber layer 102 and rubber hose 103, when the pneumatic door 101 is closing, if a person is located at the doorway, the rubber layer 102 and rubber hose 103 will contact the person first, thereby reducing the clamping strength and lowering the risk of injury. Multiple rubber layers 102 and rubber hoses 103 are arranged in a linear filling pattern on one side of the pneumatic door 101. By filling one side of the pneumatic door 101 with multiple rubber layers 102 and rubber hoses 103, the risk of injury is reduced while ensuring the pneumatic door 101 closes smoothly. For sealing, multiple racks 105 and gears 107 are provided, and the multiple racks 105 and gears 107 are arranged in a mirror symmetrical manner about the transverse center line of the pneumatic door 101. The fixing plate 109 is slidably connected to the inner side of the pneumatic door 101. The circular racks 108 and rubber hoses 103 are arranged in a one-to-one correspondence. Multiple circular racks 108 are inserted into the rubber hoses 103 to strengthen the support. One end of the rack 105 is fitted with a spring 110, which is fixedly installed on the inner side of the pneumatic door 101. When the pneumatic door 101 is opened, after losing the resistance of the door frame, the spring 110 rebounds and pushes the trigger rod 104 to slide out and reset.

[0021] Regarding the above technical solution, it should be noted that when the pneumatic door 101 is actually used, when the pneumatic door 101 moves to close, the trigger rod 104 contacts the door frame of the carriage, thereby sliding into the inside of the pneumatic door 101. At the same time, the rack 105 meshes with the gear 107, driving the gear 107 to rotate, causing the circular rack 108 to slide into the rubber hose 103. When the pneumatic door 101 closes with the door frame, the circular rack 108 is fully inserted into the inside of the rubber hose 103 for support, thereby preventing the rubber layer 102 and the rubber hose 103 from being dented and deformed. When the pneumatic door 101 is closed, if a person is at the doorway, the rubber layer 102 and the rubber hose 103 will contact the person first, thereby reducing the clamping strength and reducing the risk of injury.

[0022] Example 2: Refer to the appendix of the instruction manual. Figure 3 The stop component 200 includes a housing 201, which is fixedly installed on one side of the pneumatic door 101. A sensor 202 is fixedly installed on the inner side of the housing 201. The sensor 202 and the rubber hose 103 are arranged on the same vertical plane. A cylinder 203 is fixedly installed on the inner side of the housing 201. One end of the cylinder 203 is threadedly connected to a push rod 204. One end of the push rod 204 is provided with a pawl 205. A positioning rod 206 is hinged to the inner side of the pawl 205. The positioning rod 206 is fixedly installed on the inner side of the housing 201. A ratchet 207 is rotatably connected to the inner side of the housing 201. The ratchet 207 passes through one side of the pneumatic door 101 and is integrally set with the gear 107.

[0023] Regarding the above technical solution, it should be noted that when this device is actually used, when a person comes into contact with the rubber layer 102 and the rubber hose 103, the sensor 202 detects the contact and sends a command to the cylinder 203. At this time, the cylinder 203 pulls the push rod 204, causing the push rod 204 to deflect, thereby engaging the pawl 205 with the ratchet 207, thus preventing the ratchet 207 from rotating, and preventing the circular toothed rod 108 from being inserted into the rubber hose 103, thereby preventing injury to the person.
