Description

Technical Field

[0001] The utility model belongs to the field of passenger car pedals, and particularly relates to a control system for a passenger car door assembly and a high-platform passenger car. Background Art

[0002] Currently in the overseas market, high platforms and high-platform passenger cars adapted to high platforms have become the mainstream development trend of passenger stations. In existing high-platform passenger cars, the height of the passenger car door is set to be flush with the high platform. When the driver parks the vehicle, the passenger car door is placed as close as possible to the high platform so that passengers on the high platform can directly step into the passenger car door. When the driver parks the vehicle at a relatively remote distance from the high platform, there is a large gap between the high platform and the passenger car door, which is inconvenient for groups such as children, the elderly, or the disabled to board the vehicle; moreover, during peak hours, there is serious pushing and shoving among passengers, and the aforementioned large gap is also extremely likely to cause passengers to step into the void and fall.

[0003] Therefore, existing high-platform passenger cars generally are provided with passenger car pedals, and the passenger car pedals and the passenger car door together form a passenger car door assembly. The passenger car pedal is rotatably installed at the passenger car door so as to be flipped open when the passenger car door is opened for boarding and form a walking bridge connecting the passenger car door and the high platform; after the passenger car door is closed, the passenger car pedal is retracted. The opening and retraction of the passenger car pedal are generally realized through an independent air source, a pedal control air circuit, and a pedal flipping cylinder. The opening and closing of the passenger car door are generally realized through an independent air source, a passenger car door control air circuit, and a door rotating cylinder. Such a setting makes the control system of the passenger car door assembly on the high-platform passenger car complex and is not conducive to controlling the production cost during implementation.

Specific implementation manners

[0028] The features and performance of the present utility model will be further described in detail below in conjunction with embodiments.

[0029] The passenger vehicle pedal control system of the present utility model includes a main air source and a control air path connected to the main air source. The control air path includes a vehicle door control air path and a pedal control air path, and can control the vehicle door and the passenger vehicle pedal under the control of an electronic control unit. The vehicle door control air path and the pedal control air path share a part of the air path, which makes the passenger vehicle door assembly control system more concise and is also conducive to controlling the production cost of the passenger vehicle during implementation.

[0030] Specifically, the control system of the passenger car door assembly includes a main air source, a control air circuit connected to the main air source, and an electronic control unit. The control air circuit includes a door control air circuit. A door rotating cylinder and a door control valve for controlling the expansion and contraction of the door rotating cylinder are connected in series on the air supply pipe of the door control air circuit. A pedal control air circuit is also connected to the air supply pipe of the door control air circuit on the upstream side of the door control valve. A pedal flipping cylinder and a pedal control valve for controlling the expansion and contraction of the pedal flipping cylinder are connected in series on the air supply pipe of the pedal control air circuit. Both the door control valve and the pedal control valve are connected to the electronic control unit. In the control system with such a structure, both the door control air circuit and the pedal control air circuit are connected to the main air source and supplied with air by the main air source. By controlling the door control valve and the pedal control valve at different times through the electronic control unit, the actions of the door rotating cylinder and the pedal flipping cylinder can be controlled to realize the driving of the door and the pedal. The door control air circuit and the pedal control air circuit share a part of the air supply pipe. In this way, the structure of the air circuit is relatively simple, more convenient to arrange, occupies less laying space, and can reduce the manufacturing cost of the passenger car.

[0031] An embodiment of the control system of the passenger car door assembly of the present invention:

[0032] Reference Figures 1-3 Referring to

[0033] , the main air source 1 of the control system of the passenger car door assembly is connected with a control air circuit. The control air circuit includes a door control air circuit 2 and a pedal control air circuit 3. Therefore, the main air source 1 supplies gas medium to both the pedal control air circuit 3 and the door control air circuit 2 at the same time. A door rotating cylinder 21 and a door control valve 20 for controlling the expansion and contraction of the door rotating cylinder 21 are connected in series on the air supply pipe of the door control air circuit 2. A pedal flipping cylinder 31 and a pedal control valve 30 for controlling the expansion and contraction of the pedal flipping cylinder 31 are connected in series on the air supply pipe of the pedal control air circuit 3. Both the door control valve 20 and the pedal control valve 30 are connected to an electronic control unit (not shown in the figure). Among them, the pedal control air circuit 3 is connected to the air supply pipe of the door control air circuit 2 at a position upstream of the door control valve 20.

[0034] For the door control air circuit 2, the door control valve 20 is a reversing valve, preferably a two-position five-way reversing valve. When the door control valve 20 is a two-position five-way valve, the two air outlets of the door control valve 20 are respectively connected to the rod chamber and the rodless chamber of the door rotating cylinder 21, both exhaust ports are connected to the outside, and the air inlet is connected to the main air source 1. The door control valve 20 further includes an electromagnetic assembly DT5 and an electromagnetic assembly DT6 for driving the door control valve 20 to perform a reversing action. When the door rotating cylinder 21 performs an extending action, the air outlet connected to the rodless chamber is connected to the air inlet, and the air outlet connected to the rod chamber is connected to one of the exhaust ports, so that the telescopic end of the door rotating cylinder 21 extends under the action of the gas medium. When the door rotating cylinder 21 performs a retracting action, the electromagnetic assemblies DT5 and DT6 switch the connection direction of the pipelines in the door control valve 20, so that the air outlet connected to the rodless chamber is connected to the outside, and the air outlet connected to the rod chamber is connected to the main air source 1. So that the telescopic end of the door rotating cylinder 21 retracts under the action of the gas medium. Such a setting can simplify the door control air circuit 2 to further reduce the complexity of the control system of the passenger door assembly. In other embodiments, the pedal control valve 30 can also be a two-position four-way reversing valve. The two air outlets of the door control valve 20 are respectively connected to the rod chamber and the rodless chamber of the door rotating cylinder 21, the exhaust port is connected to the outside, and the air inlet is connected to the main air source 1. The door control valve 20 further includes an electromagnetic assembly for driving the door control valve 20 to perform a reversing action. When the door rotating cylinder 21 performs an extending action, the air outlet connected to the rodless chamber is connected to the air inlet, and the air outlet connected to the rod chamber is connected to the exhaust port, so that the telescopic end of the door rotating cylinder 21 extends under the action of the gas medium. When the door rotating cylinder 21 needs to perform a retracting action, the electromagnetic assembly drives the valve core to act, switching the connection direction of the pipelines in the pedal control valve 30, so that the air outlet connected to the rodless chamber is connected to the outside, and the air outlet connected to the rod chamber is connected to the main air source 1. So that the telescopic end of the door rotating cylinder 21 retracts under the action of the gas medium.

[0035] The aforementioned pedal control valve 30 is a reversing valve, preferably a two-position five-way reversing valve. When the pedal control valve 30 is a two-position five-way valve, the two air outlets of the pedal control valve 30 are respectively connected to the rod chamber and the rodless chamber of the pedal turning cylinder 31, both exhaust ports are connected to the outside, and the air inlet is connected to the pedal control air circuit 3. The pedal control valve 30 further includes an electromagnetic assembly DT1 and an electromagnetic assembly DT2 for driving the pedal control valve 30 to perform a reversing action. When the pedal turning cylinder 31 performs an extending action, the air outlet connected to the rodless chamber is connected to the air inlet, and the air outlet connected to the rod chamber is connected to one of the exhaust ports, so that the telescopic end of the pedal turning cylinder 31 extends under the action of the gas medium. When the pedal turning cylinder 31 performs a retracting action, the electromagnetic assembly DT1 and the electromagnetic assembly DT2 switch the connection direction of the pipelines in the pedal control valve 30, so that the air outlet connected to the rodless chamber is connected to the outside, and the air outlet connected to the rod chamber is connected to the main air source 1. So that the telescopic end of the pedal turning cylinder 31 retracts under the action of the gas medium. Such a setting can simplify the pedal control air circuit 3 to further reduce the complexity of the control system of the passenger door assembly. In other embodiments, the pedal control valve 30 can also be a two-position four-way reversing valve. The two air outlets of the pedal control valve 30 are respectively connected to the rod chamber and the rodless chamber of the pedal turning cylinder 31, the exhaust port is connected to the outside, and the air inlet is connected to the passenger door air source. The pedal control valve 30 further includes an electromagnetic assembly for driving the pedal control valve 30 to perform a reversing action. When the pedal turning cylinder 31 performs an extending action, the air outlet connected to the rodless chamber is connected to the air inlet, and the air outlet connected to the rod chamber is connected to the exhaust port, so that the telescopic end of the pedal turning cylinder 31 extends under the action of the gas medium. When the pedal turning cylinder 31 needs to perform a retracting action, the electromagnetic assembly drives the valve core to move, switching the connection direction of the pipelines in the pedal control valve 30, so that the air outlet connected to the rodless chamber is connected to the outside, and the air outlet connected to the rod chamber is connected to the main air source 1. So that the telescopic end of the pedal turning cylinder 31 retracts under the action of the gas medium.

[0036] Based on the above embodiments, another optimized embodiment is provided herein. The control system of the passenger car door assembly further includes a locking control air circuit 4. The locking control air circuit 4 includes a locking cylinder 41 and a locking control valve 40. The locking control air circuit 4 is connected to the main air source 1, and the locking control valve 40 and the locking cylinder 41 are connected in series on the locking control air circuit 4 in sequence. In this embodiment, a latch serving as a locking mechanism is provided on the passenger car pedal. After the passenger car pedal is retracted to the in-place position, the latch can extend under the drive of the locking cylinder 41 and block against the passenger car body to lock the passenger car pedal in the retracted state. In the above structure, the locking mechanism, the passenger car pedal, and the passenger car door are powered by the same main air source 1. This makes the control system of the passenger car door assembly more concise, occupies less space, and is also beneficial to controlling the production cost of the passenger car during implementation. In order to reduce the load of a single locking cylinder 41 and the pedal turning cylinder 31, in this embodiment, the locking cylinder 41 and the pedal turning cylinder 31 can be arranged in pairs.

[0037] Similarly, the aforementioned locking control valve 40 is a reversing valve, preferably a two-position five-way reversing valve. When the locking control valve 40 is a two-position five-way valve, the two air outlets of the locking control valve 40 are respectively connected to the rodless chamber and the rod chamber of the locking cylinder 41, and both exhaust ports are connected to the outside, and the air inlet is connected to the passenger car door air source. The locking control valve 40 further includes an electromagnetic assembly DT3 and an electromagnetic assembly DT4 for driving the locking control valve 40 to perform a reversing action. When the locking cylinder 41 performs an extending action, the air outlet connected to the rodless chamber is connected to the air inlet, and the air outlet connected to the rod chamber is connected to one of the exhaust ports, so that the telescopic end of the locking cylinder 41 extends under the action of the gas medium. When the locking cylinder 41 performs a retracting action, the electromagnetic assembly DT3 and the electromagnetic assembly DT4 switch the connection direction of the pipelines in the locking control valve 40, so that the air outlet connected to the rodless chamber is connected to the outside, and the air outlet connected to the rod chamber is connected to the main air source 1. So that the telescopic end of the locking cylinder 41 retracts under the action of the gas medium. Such a setting can simplify the locking control air circuit 4 to further reduce the complexity of the control system of the passenger car door assembly. In other embodiments, the locking control valve 40 can also be a two-position four-way reversing valve. The two air outlets of the locking control valve 40 are respectively connected to the rod chamber and the rodless chamber of the locking cylinder 41, the exhaust port is connected to the outside, and the air inlet is connected to the passenger car door air source. The locking control valve 40 further includes an electromagnetic assembly for driving the locking control valve 40 to perform a reversing action. When the locking cylinder 41 performs an extending action, the air outlet connected to the rodless chamber is connected to the air inlet, and the air outlet connected to the rod chamber is connected to the exhaust port, so that the telescopic end of the locking cylinder 41 extends under the action of the gas medium. When the locking cylinder 41 needs to perform a retracting action, the electromagnetic assembly drives the valve core to act to switch the connection direction of the pipelines in the locking control valve 40, so that the air outlet connected to the rodless chamber is connected to the outside, and the air outlet connected to the rod chamber is connected to the main air source 1. So that the telescopic end of the locking cylinder 41 retracts under the action of the gas medium.

[0038] Based on the foregoing structure, the electronic control unit can be made to include a delay module. The delay module can control the pedal control air circuit 3 to retract the flap after a predetermined time (such as 2 seconds or 3 seconds) when the bus door is closed. Such a setting can make the action of retracting the bus pedal execute later than the action of closing the bus door, so as to prevent the action of retracting the bus pedal from interfering with the action of closing the bus door.

[0039] In an emergency, the bus door assembly should have the ability to be opened emergently. Therefore, a bleed valve is connected to the control air circuit to be used for exhausting and relieving the pressure of the gas in the door control air circuit 2, the pedal control air circuit 3, and the locking control air circuit 4. At this time, all the gas medium in the bus door assembly control system is discharged. In order to ensure that the bus pedal can be normally opened, in a preferred embodiment, an elastic reset unlocking mechanism can be provided in the locking cylinder 41. The elastic reset unlocking mechanism preferably adopts a compression spring, which is arranged in the rod chamber of the locking cylinder 41 and is in a compressed state when the telescopic end of the locking cylinder 41 extends. After the gas in the locking cylinder 41 is discharged, the elastic reset unlocking mechanism extends back, driving the telescopic end of the locking cylinder 41 to reset and retract to unlock the bus pedal.

[0040] Embodiment of the high-platform bus of the present utility model:

[0041] A high-platform bus includes a bus main body and a bus door assembly. Among them, the bus main body is of an existing structure and includes conventional bus components such as a vehicle frame and a chassis. The bus door assembly includes a bus door provided on the bus main body and a bus pedal hinged at the doorway of the bus door. A bus door assembly control system for controlling the bus door assembly is provided on the bus main body. The bus door assembly control system is the design concept of the bus door assembly control system described in the embodiments of the present utility model and will not be elaborated here.

[0042] A gear-rack transmission structure is provided between the bus pedal and the bus main body. The rack of the gear-rack transmission mechanism is fixedly connected to the telescopic end of the pedal turning cylinder 31 of the bus door assembly control system, and the gear is installed at the hinge of the bus pedal and rotates synchronously with the bus pedal. A locking mechanism for locking and holding the bus pedal is also provided on the bus door. The locking mechanism is specifically a latch provided on the bus pedal. The latch is connected to the telescopic end of the locking cylinder 41 so as to extend or retract along with the telescopic end of the locking cylinder 41. After the bus pedal is retracted, the latch extends to lock and hold the bus pedal at the current position. Before the bus door is opened, the latch retracts to unlock the bus pedal.

[0043] When the bus door assembly and the bus door assembly control system are working, they altogether go through four states as Figure 3 described.

[0044] Initial state: At this time, the passenger car pedal is in the upright retracted state, and both the pedal flipping cylinder 31 and the locking cylinder 41 are in the extended state. At this time, the electromagnetic components DT1 and DT3 are not working, and the electromagnetic components DT2 and DT4 are in the working state.

[0045] Execution state 1: When the passenger car door needs to be opened, as shown in Figure 2 shown, the driver gives an opening signal to the passenger car door through the button on the instrument panel, and at the same time gives a switching signal to the locking control valve 40. At this time, the electromagnetic component DT3 of the locking cylinder 41 works, and the electromagnetic component DT4 does not work, causing the locking cylinder 41 to start retracting. At this time, the electromagnetic components DT1 and the electronic component DT2 of the pedal flipping cylinder 31 are in the switching preparation state. That is, the locking cylinder 41 is in the unlocked state, and the pedal flipping cylinder 31 is in the opening preparation state.

[0046] Execution state 2: At this time, the electromagnetic components DT1 and DT2 of the first solenoid valve exchange states, that is, the electromagnetic component DT1 works, and the electromagnetic component DT2 does not work. The telescopic end of the pedal flipping cylinder 31 extends and drives the passenger car pedal to fall. Then, the door control valve 20 can be controlled to act, and then the door can be opened.

[0047] Execution state 3: When the passenger car door needs to be closed, the driver gives a closing signal to the passenger car door through the button on the instrument panel. The door control valve 20 acts to close the passenger car door first, and at the same time gives a closing signal to the passenger car pedal. At this time, the electromagnetic component DT3 of the locking cylinder 41 works, and DT4 does not work, that is, the locking cylinder 41 is in the retracted state. The electromagnetic components DT1 and DT2 of the pedal control valve 30 are in the switching preparation state. That is, at this time, the locking cylinder 41 is in the unlocked state, and the passenger car pedal is in the closing preparation state. Under the action of the delay module of the electronic control unit, the electromagnetic components DT1 and DT2 of the pedal control valve 30 exchange states after a predetermined time delay. At this time, the electromagnetic component DT1 of the pedal control valve 30 does not work, and the electromagnetic component DT2 works. After the passenger car pedal is closed in place, at this time, the electromagnetic component DT3 of the locking cylinder 41 does not work, and the electromagnetic component DT4 works, causing the locking cylinder 41 to start extending until the lock latch stops against the passenger car body. That is, at this time, the passenger car door assembly and the passenger car door assembly control system return to the initial state.

[0048] It should be noted that the above working process is only a specific example for the convenience of explanation. In other embodiments, such as adding a reversing gear between the gear and the rack, the working states of the electromagnetic components DT1, DT2, DT3, and DT4 during the working process are exactly opposite to those in the previous working process, which will not be elaborated here.

[0049] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. The patent protection scope of the present utility model is subject to the claims. Any equivalent structural changes made by using the content of the specification and drawings of the present utility model shall likewise be included within the protection scope of the present utility model.
