Technical Field
[0001] The invention relates to the technical field of vehicle manufacturing, and in particular to a boarding system at the front of a vehicle and a vehicle. Background Art
[0002] With the development of the automobile industry, various types of cars have gradually become the main means of transportation for people to travel and transport. After a long-distance run, the outer surface of the car is easily covered with dust (especially the front windshield), thereby blocking the driver's field of vision. Therefore, it is necessary to clean it in time after parking. Some large commercial vehicles have a high front, and it is difficult for cleaning personnel to directly clean the front windshield. Therefore, in the related art, a pedal structure is installed at the front of such vehicles to facilitate cleaning personnel to get on the vehicle and clean the front windshield.
[0003] However, when the vehicle is traveling at high speed, the windward airflow at the front of the vehicle will form eddies and turbulence at the open boarding steps and protruding boarding handrails, thereby increasing the wind resistance of the vehicle while driving, which means increasing the vehicle's fuel consumption and is not conducive to the vehicle's economy. Summary of the invention
[0004] In view of the problem that the boarding structure at the front of the vehicle in the prior art may cause great wind resistance to the vehicle, the present application provides a boarding system at the front of the vehicle, which includes:

[0019] When the pedal is flush with the outer surface of the front enclosure, the central controller drives the armrest assembly to perform a retraction action, and when the pedal and the front enclosure are no longer flush, the control assembly drives the armrest assembly to perform an extension action.
[0020] In some embodiments, a pressure sensor is provided on the pedal assembly, the pressure sensor is connected to the central controller signal, and the pressure sensor is used to detect the pressure value of the pedal when it is in use; wherein,

DETAILED DESCRIPTION
[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0036] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. Figure 1 and Figure 2 As shown, the present application provides a vehicle front boarding system, which includes: a pedal assembly 1, an armrest assembly 3 and a main control assembly; wherein,
[0037] A pedal assembly 1, which is used to be assembled on the front wall 2 of the vehicle, and the pedal assembly 1 can be turned over on the front wall 2; an armrest assembly 3, which is used to be assembled on the front wall 2, and the armrest assembly 3 can be telescopic on the front wall 2; a main control assembly, which includes an opening part and a closing part, and the opening part and the closing part are both used to be assembled in the driving room of the vehicle;
[0038] When the opening part is triggered, the pedal assembly 1 enters the open state by flipping so that its outer surface is flush with the outer surface of the front enclosure 2, and enters the closed state, and the armrest assembly 3 extends out of the front enclosure 2 to enter the closed state; when the closing part is triggered, the pedal assembly 1 enters the closed state by flipping so that its outer surface is flush with the outer surface of the front enclosure 2, and the armrest assembly 3 enters the closed state by retracting so that its outer surface is flush with the outer surface of the front enclosure 2.
[0039] Preferably, the opening portion and the closing portion may be arranged in the cab for operation by the driver.
[0040] It should be noted that the applicant has found in his research that when a large vehicle is traveling at high speed, the windward airflow at the front of the vehicle will form eddies and turbulence at the open boarding step and the protruding fixed handrail structure, increasing the vehicle's wind resistance coefficient Cd by about 0.003. According to the empirical formula for the power consumption of the vehicle to overcome wind resistance, W = Cd*V 2It can be seen that the existing step and convex handrail structure design will increase the vehicle's driving power consumption, that is, it will increase the vehicle's fuel consumption. However, the step and the convex handrail are indispensable components for vehicle cleaning.
[0041] In view of the occurrence of such problems, in the present application, when the boarding system is in use, the pedal assembly 1 is partially kept parallel to the horizontal plane of the vehicle body to assist the staff to better obtain the support point for boarding. The handrail assembly 3 is extended to allow the staff to obtain a better force point for boarding. When the cleaning is completed and the vehicle is driven normally, the main control assembly switches the pedal assembly 1 and the handrail assembly 3 to the closed state. At this time, Figure 4 and Figure 6 As shown, the armrest assembly 3 and the pedal assembly 1 are both retracted or turned back into the front wall 2 of the car, and the outer surfaces of the two (i.e., the side of the armrest assembly 3 away from the vehicle body after retracting and the side of the pedal assembly 1 away from the vehicle body after rotating toward the front wall 2) are flush with the surface of the front wall 2. In this way, during normal driving, the boarding system at the front of the car will not form eddies and turbulence at the front of the vehicle, increasing the wind resistance of driving. When the armrest assembly 3 and the pedal assembly 1 are both in the closed state, the boarding system is in the closed state.
[0042] Furthermore, in order to better prevent the driver from erroneously operating the boarding system while driving, the control component 4 specifically includes: a vehicle condition detection unit and a central controller 41; wherein,
[0043] A vehicle condition detection unit, which is used to be assembled on the vehicle, and the vehicle condition detection unit is used to detect the vehicle operation status information; a central controller 41, which is used to be assembled in the cab of the vehicle, and the central controller 41 is connected to the vehicle condition detection unit signal. When the opening part is triggered and the vehicle operation status information meets the preset standard requirements, the central controller 41 drives the pedal assembly 1 and the armrest assembly 3 to perform an opening action or a closing action.
[0044] Furthermore, the preset standard requirement includes: the vehicle speed of the vehicle remains at 0 within a preset time.
[0045] In this way, when the vehicle is started, even if the driver mistakenly switches the on-board system to the open state through the main control component during driving, the central controller 41 can automatically maintain it in the closed state with low wind resistance based on the driving status.
[0046] In some specific embodiments, Figure 3 As shown, the pedal assembly 1 comprises: a pedal 11, a pedal driving part 12 and a locking part 13; wherein,
[0047] A pedal 11 is movably connected to a front bumper bracket 21 of the front enclosure 2, and the pedal 11 can be flush with the outer surface of the front enclosure 2 by flipping; a pedal driving unit 12 is connected to the pedal 11, the pedal driving unit is signal-connected to the control component 4, and the pedal driving unit 12 is used to drive the pedal 11 to flip; a locking unit 13 is assembled on the pedal 11 and the front bumper bracket 21, and the locking unit 13 is used to lock the pedal 11 so that the pedal 11 remains flush with the front enclosure 2.
[0048] It is worth noting that the pedal drive unit 12 can be driven by a motor. The locking unit 13 in the present application is a safety component in the closed state. It prevents the pedal drive unit 12 from malfunctioning during driving and automatically switching to the use state. Specifically, Figure 3 As shown, the locking portion 13 includes: a locking tongue 131 and a hinge lock 132; wherein,
[0049] The locking tongue 131 is used to be assembled on the front bumper bracket 21; the hinge lock 132 is assembled on the pedal 11, and the hinge lock 132 is used to cooperate with the locking tongue 131 to limit the turning action of the pedal 11. The operator can lock the two manually.
[0050] Preferably, in order to better achieve the purpose of locking insurance, in case of an unexpected failure of the pedal driving unit 12, the locking unit 13 is connected to the central controller 41 by signal, and when the vehicle running state information does not meet the preset standard requirements, the central controller 41 drives the locking unit 13 to lock the pedal 11. That is, after starting to drive, the locking unit 13 will automatically lock.
[0051] In order to optimize the control process, the present application provides a preferred embodiment, wherein the pedal assembly 1 further comprises: a touch switch 14, which is used to be arranged on a side of the front bumper bracket 21 close to the pedal 11, and the touch switch 14 is connected to the central controller 41 by signal, and the touch switch 14 is used to detect whether the pedal 11 is flush with the outer surface of the front enclosure 2; wherein,
[0052] When the pedal 11 is flush with the outer surface of the front enclosure 2, the control component drives the armrest assembly 3 to perform a retraction action. When the pedal 11 and the front enclosure 2 are no longer flush with each other, the control component drives the armrest assembly 3 to perform an extension action.
[0053] It can be understood that the above embodiment realizes the linkage control of the pedal assembly 1 and the armrest assembly 3. That is, the control assembly 4 does not need to perform signal judgment on the control of the armrest assembly 3 again. Instead, the extension and retraction of the armrest assembly 3 is realized according to the movement state of the pedal 11. When the pedal 11 is flipped to be parallel to the vehicle body, the touch switch 14 is no longer triggered, and then the central controller 41 directly drives the armrest assembly 3 to extend out of the front wall 2 of the car. When the pedal 11 is switched to the closed state, the pedal 11 contacts the touch switch 14 after flipping, thereby triggering the touch switch. The central controller 41 drives the armrest assembly 3 to retract into the front wall 2, and keeps the exposed surface of the armrest assembly 3 flush with the surface of the front wall 2.
[0054] Furthermore, based on the above embodiment, in order to prevent the user from accidentally touching the touch switch 14 when stepping on the pedal 11 during the process of cleaning the front windshield, causing the armrest assembly 3 to retract unexpectedly and causing the cleaning personnel to fall, the pedal assembly 1 is provided with a pressure sensor 5, which is connected to the central controller 41 by signal, and the pressure sensor 5 is used to detect the pressure value of the pedal 11 when it is in use; wherein,
[0055] When the pedal assembly is in use and the pressure value is greater than a preset threshold, the central controller 41 drives the armrest assembly 3 to maintain the use state.
[0056] It is understandable that the above-mentioned preset threshold value needs to be preset according to the pressure of the human body stepping on the pedal 11. When the pressure value is greater than the preset threshold value, it is judged that a person is working on the pedal 11. At this time, even if the touch switch 14 is triggered, the armrest assembly 3 remains extended.
[0057] The present application also provides a specific embodiment of an armrest assembly 3, which includes: two armrest assemblies 31 and a pneumatic telescopic rod 32; wherein, the two armrest assemblies 31 are assembled on the upper cross beam of the front enclosure 2 of the vehicle; the pneumatic telescopic rod 32 is connected to the armrest assembly 31, and the pneumatic telescopic rod 32 can drive the armrest assembly 31 to extend out of the front enclosure 2 or be flush with the outer surface of the front enclosure 2 by telescoping.
[0058] Specifically, the armrest assembly 31 includes: an armrest handle and an armrest base. The pneumatic telescopic rod 32 includes: a pneumatic strut, a mechanical strut, a spring and a three-way solenoid valve. The three-way solenoid valve includes: an air inlet, an air outlet and an exhaust port. The air inlet is connected to the air circuit of the whole vehicle, the air outlet supplies air to the pneumatic strut, and the exhaust port is connected to the outside air and is normally open. The solenoid valve electrical signal is connected to the three-way solenoid valve signal to receive a connection or exhaust action signal. When the solenoid valve is connected to the air inlet, the exhaust port is closed, the pneumatic strut is inflated and extended, the armrest handle is extended, and the spring is stretched at the same time. When the solenoid valve air inlet is closed and the exhaust port is opened, the air pressure in the pneumatic strut is reduced, and the spring drives the armrest handle to retract, and finally it is flush with the outer surface of the vehicle body. The central controller 41 can be selected as the vehicle cab domain central controller ECU, which is mostly installed in the cab dashboard, receives the vehicle speed signal, contact switch signal, pressure sensor signal, and sends action signals to the three-way solenoid valve and lock pin motor signal.
[0059] On the other hand, the present application provides a car, which includes: a boarding system, which includes: a pedal assembly 1, an armrest assembly 3 and a main control assembly; wherein,
[0060] A pedal assembly 1, which is used to be assembled on the front wall 2 of the vehicle, and the pedal assembly 1 can be turned over on the front wall 2; an armrest assembly 3, which is used to be assembled on the front wall 2, and the armrest assembly 3 can be telescopic on the front wall 2; a main control assembly, which includes an opening part and a closing part, and the opening part and the closing part are both used to be assembled in the driving room of the vehicle;
[0061] When the opening part is triggered, the pedal assembly 1 enters the open state by flipping so that its outer surface is flush with the outer surface of the front enclosure 2, and enters the closed state, and the armrest assembly 3 extends out of the front enclosure 2 to enter the closed state; when the closing part is triggered, the pedal assembly 1 enters the closed state by flipping so that its outer surface is flush with the outer surface of the front enclosure 2, and the armrest assembly 3 enters the closed state by retracting so that its outer surface is flush with the outer surface of the front enclosure 2.
[0062] It should be noted that the applicant has found in his research that when a large vehicle is traveling at high speed, the windward airflow at the front of the vehicle will form eddies and turbulence at the open boarding step and the protruding fixed handrail structure, increasing the vehicle's wind resistance coefficient Cd by about 0.003. According to the empirical formula for the power consumption of the vehicle to overcome wind resistance, W = Cd*V 2 It can be seen that the existing step and convex handrail structure design will increase the vehicle's driving power consumption, that is, it will increase the vehicle's fuel consumption. However, the step and the convex handrail are indispensable components for vehicle cleaning.
[0063] In view of the occurrence of such problems, in the present application, when the boarding system is in use, the pedal assembly 1 is partially kept parallel to the horizontal plane of the vehicle body to assist the staff to better obtain the support point for boarding. The handrail assembly 3 is extended to allow the staff to obtain a better force point for boarding. When the cleaning is completed and the vehicle is driven normally, the main control assembly switches the pedal assembly 1 and the handrail assembly 3 to the closed state. At this time, Figure 4 and Figure 6 As shown, the armrest assembly 3 and the pedal assembly 1 are both retracted or flipped back into the front wall 2 of the car (the armrest assembly 3 and the pedal assembly 1 are both in a closed state), and the exposed outer surfaces of the two are flush with the surface of the front wall 2. In this way, during normal driving, the boarding system at the front of the car will not form eddies and turbulence at the front of the vehicle, thereby increasing the wind resistance of driving.
[0064] Furthermore, in order to better prevent the driver from erroneously operating the boarding system while driving, the control component 4 specifically includes: a vehicle condition detection unit and a central controller 41; wherein,
[0065] A vehicle condition detection unit, which is used to be assembled on the vehicle, and the vehicle condition detection unit is used to detect the vehicle operation status information; a central controller 41, which is used to be assembled in the cab of the vehicle, and the central controller 41 is connected to the vehicle condition detection unit signal. When the opening part is triggered and the vehicle operation status information meets the preset standard requirements, the central controller 41 drives the pedal assembly 1 and the armrest assembly 3 to perform an opening action or a closing action.
[0066] Furthermore, the preset standard requirement includes: the vehicle speed of the vehicle remains at 0 within a preset time.
[0067] In this way, when the vehicle is started, even if the driver mistakenly switches the on-board system to the open state through the main control component during driving, the central controller 41 can automatically maintain it in the closed state with low wind resistance based on the driving status.
[0068] In some specific embodiments, Figure 3 As shown, the pedal assembly 1 comprises: a pedal 11, a pedal driving part 12 and a locking part 13; wherein,
[0069] A pedal 11 is movably connected to a front bumper bracket 21 of the front enclosure 2, and the pedal 11 can be flush with the outer surface of the front enclosure 2 by flipping; a pedal driving unit 12 is connected to the pedal 11, the pedal driving unit is signal-connected to the control component 4, and the pedal driving unit 12 is used to drive the pedal 11 to flip; a locking unit 13 is assembled on the pedal 11 and the front bumper bracket 21, and the locking unit 13 is used to lock the pedal 11 so that the pedal 11 remains flush with the front enclosure 2.
[0070] It is worth noting that the pedal drive unit 12 can be driven by a motor. The locking unit 13 in the present application is a safety component in the closed state. It prevents the pedal drive unit 12 from malfunctioning during driving and automatically switching to the use state. Specifically, Figure 3 As shown, the locking portion 13 includes: a locking tongue 131 and a hinge lock 132; wherein,
[0071] The locking tongue 131 is used to be assembled on the front bumper bracket 21; the hinge lock 132 is assembled on the pedal 11, and the hinge lock 132 is used to cooperate with the locking tongue 131 to limit the turning action of the pedal 11. The operator can lock the two manually.
[0072] Preferably, in order to better achieve the purpose of locking insurance, in case of an unexpected failure of the pedal driving unit 12, the locking unit 13 is connected to the central controller 41 by signal, and when the vehicle running state information does not meet the preset standard requirements, the central controller 41 drives the locking unit 13 to lock the pedal 11. That is, after starting to drive, the locking unit 13 will automatically lock.
[0073] In order to optimize the control process, the present application provides a preferred embodiment, wherein the pedal assembly 1 further comprises: a touch switch 14, which is used to be arranged on a side of the front bumper bracket 21 close to the pedal 11, and the touch switch 14 is connected to the central controller 41 by signal, and the touch switch 14 is used to detect whether the pedal 11 is flush with the outer surface of the front enclosure 2; wherein,
[0074] When the pedal 11 is flush with the outer surface of the front enclosure 2, the control component drives the armrest assembly 3 to perform a retraction action. When the pedal 11 and the front enclosure 2 are no longer flush with each other, the control component drives the armrest assembly 3 to perform an extension action.

[0079] The present application also provides a specific embodiment of an armrest assembly 3, which includes: two armrest assemblies 31 and a pneumatic telescopic rod 32; wherein, the two armrest assemblies 31 are assembled on the upper cross beam of the front enclosure 2 of the vehicle; the pneumatic telescopic rod 32 is connected to the armrest assembly 31, and the pneumatic telescopic rod 32 can drive the armrest assembly 31 to extend out of the front enclosure 2 or be flush with the outer surface of the front enclosure 2 by telescoping.
[0080] Specifically, the armrest assembly 31 includes: an armrest handle and an armrest base. The pneumatic telescopic rod 32 includes: a pneumatic strut, a mechanical strut, a spring and a three-way solenoid valve. The three-way solenoid valve includes: an air inlet, an air outlet and an exhaust port.

The central controller 41 can be selected as the vehicle cab domain central controller ECU, which is mostly installed in the cab dashboard, receives the vehicle speed signal, contact switch signal, pressure sensor signal, and sends action signals to the three-way solenoid valve and lock pin motor signal.
[0081] This application provides a specific control process embodiment which includes:
[0082] A. The opening steps include:
[0083] S1. Vehicle speed signal detection and judgment: when the vehicle speed is not 0, the locking part 13 is locked, and the opening part does not work even if the pedal assembly 1 and the armrest assembly 3 are triggered. When the vehicle speed = 0, the locking part 13 is unlocked, and the main control assembly can use the opening and closing functions normally.
[0084] S2. When the vehicle speed = 0, the opening part is triggered.
[0085] S3. The central controller 41 sends a flip signal to the pedal assembly 1.
[0086] S4. The pedal 11 of the pedal assembly 1 triggers the touch switch 14 by flipping, and the touch switch 14 sends a signal to the central controller 41, and the central controller 41 then drives the armrest assembly 3 to extend and perform the opening action.
[0087] S5. The boarding system is on.
[0088] B. Closing steps:
[0089] Active control step: when the pressure sensor 5 on the pedal 11 shows that the pressure on the pedal 11 is lower than a preset standard, the closing part can be normally triggered to enable the boarding system to perform a closing action.
[0090] Passive control steps: The vehicle speed signal is first detected and judged. When the vehicle speed is not 0 and the pressure sensor 5 on the pedal 11 shows that the pressure on the pedal 11 is lower than the preset standard, the central controller 41 executes the closing action.
[0091] In summary, the present invention provides a movable flap and an armrest structure, so that when the car is parked and needs to be cleaned, the boarding system can be switched to the use state, and when the car is driving normally, it is switched to the closed state to reduce the driving wind resistance. As a result, the boarding system of the present application not only facilitates the cleaning personnel to get on the car to clean the front of the car, but also reduces the problem of increased fuel consumption caused by wind resistance during normal driving of the car, and is more economical. Furthermore, the present application simplifies the judgment control process of the central controller through the linkage control of the armrest and the pedal.
