Description

Technical Field

[0001] The invention belongs to the technical field of unmanned monorail vehicles, and more specifically, relates to an opening and closing mechanism of an opening and closing cover of an unmanned monorail vehicle. The invention also relates to a control method of the opening and closing mechanism of an opening and closing cover of an unmanned monorail vehicle. Background Art

[0002] Unmanned monorail vehicles are gradually becoming popular in rail transit in small and medium-sized cities due to their unique medium-capacity characteristics. In the process of developing unmanned monorail vehicles, intelligence and automation will be the trend of vehicle development. In order to maintain a good streamlined and beautiful appearance, the monorail train hides the hook inside the entire head mask. The head cover (opening and closing cover) can be opened when connected. This device for opening the head cover is called an opening and closing mechanism. The defects of the prior art are: 1: Unmanned monorail vehicles previously adopted a purely mechanical manual structure, without a power source, and could not achieve automatic control. 2: The entire set of manually flipped opening and closing mechanisms is pushed out by gas springs. The gas springs are affected by temperature. The temperature drop in winter may cause insufficient force, and the force increases when the temperature rises in summer, resulting in unstable performance. 3: Manual opening and closing cannot be closed automatically, and it needs to be manually closed outside the vehicle, and it cannot be closed outside the vehicle when the track is energized, which affects operation. 4: The manual opening and closing operation mode causes excessive force when opening and closing, resulting in the opening and closing cover hitting the glass for a long time, causing the opening and closing cover to be damaged and broken. 5: Manual mechanical control is required to adjust the two electric locks synchronously, otherwise there will be a risk of jamming and it will be difficult to operate reliably.

[0003] In the prior art, there is a technology named "A monorail vehicle hood opening and closing device that is easy to install and maintain" and with a publication (announcement) number of "CN114559972B". This technology provides a monorail vehicle hood opening and closing device that is easy to install and maintain, including a hood body and a hatch connected to the hood body. The top of the side wall of the hatch is provided with a mounting plate. Two groups of the mounting plates are rotatably connected to the hood body through an adjustment unit. The present invention has a simple structure and is easy to operate. The hood body can be driven to rotate and open and close within a certain range through two groups of adjustment units, thereby realizing rapid disassembly and maintenance of the hood body.

[0004] However, this technology does not involve the technical problems and technical solutions of the present application. Summary of the invention

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is:

[0007] The present invention discloses an opening and closing mechanism for an opening and closing cover of an unmanned monorail vehicle. A cantilever mechanism is arranged at the front of a mechanism frame, the cantilever mechanism comprises an upper cantilever and a lower cantilever, the upper cantilever is movably connected to an upper position at the front of the mechanism frame, the lower cantilever is movably connected to a lower position at the front of the mechanism frame, a telescopic component is arranged at the lower part of the mechanism frame, the telescopic component is movably connected to one end of a first connecting rod of a connecting mechanism, and the other end of the first connecting rod is movably connected to the lower cantilever.

[0008] The telescopic rod of the telescopic component is movably connected to one end of the second connecting rod of the connecting mechanism, and the other end of the second connecting rod is movably connected to the front part of the mechanism frame.

[0009] The upper cantilever of the cantilever mechanism is a bent structure, and the upper cantilever includes a first section of the upper cantilever, a second section of the upper cantilever, and a third section of the upper cantilever. The first section of the upper cantilever and the second section of the upper cantilever form a right angle or an obtuse angle, and the second section of the upper cantilever and the third section of the upper cantilever form an obtuse angle.

[0010] The lower cantilever of the cantilever mechanism is a bent structure, and the lower cantilever includes a first section of the lower cantilever, a second section of the lower cantilever, and a third section of the lower cantilever. The first section of the lower cantilever and the second section of the lower cantilever form a right angle or an obtuse angle, and the second section of the lower cantilever and the third section of the lower cantilever form an obtuse angle.

[0011] The front end of the upper cantilever and the front end of the lower cantilever of the cantilever mechanism are connected to the opening and closing cover 8 respectively.

[0012] The end of the first section of the upper suspension of the upper cantilever is movably connected to the upper front position of the frame through a pin shaft, and the first section of the lower suspension of the lower cantilever is movably connected to the lower front position of the frame. One end of the first connecting rod connected to the lower cantilever is movably connected to the joint of the second section of the lower cantilever and the third section of the lower cantilever through a pin shaft.

[0013] The third section of the upper suspension of the upper cantilever and the third section of the lower suspension of the lower suspension are movably connected to the connecting seat through a pin shaft respectively, and the connecting seat is fixedly connected to the inner side surface of the opening and closing cover.

[0014] The telescopic component is an electric push rod, the telescopic component is connected to the control box through wires, and the control box is connected to the electric lock through wires.

[0015] The electric lock comprises an electric lock body, in which a small motor is arranged, and the driving teeth of the small motor mesh with the lock tongue teeth on the lock tongue.

[0016] The present invention also relates to a control method for an opening and closing mechanism of an unmanned monorail vehicle opening and closing cover, which has simple steps and can realize automatic opening and closing of the opening and closing cover without modifying the vehicle body mask and the opening and closing cover, has a stable output force that is not affected by the temperature, ensures that the mechanism opens and closes slowly and smoothly without strong impact, protects the opening and closing cover from damage by impact, and realizes synchronous locking and unlocking of the electric lock.

[0017] The steps of the control method of the opening and closing mechanism of the opening and closing cover of the unmanned monorail vehicle are as follows:

[0018] S1. When the opening and closing cover needs to be controlled to flip up and open, the control box controls the telescopic component to extend, and the telescopic component pushes the first connecting rod to rotate in one direction. The first connecting rod applies force to the lower cantilever, and the lower cantilever flips upward around the front of the mechanism frame, driving the opening and closing cover to leave the opening and closing cover setting opening at the front of the vehicle body until the opening and closing cover flips upward to a position above the vehicle body;

[0019] S2. When the opening and closing cover needs to be controlled to flip down and close, the control box controls the telescopic component to retract, and the telescopic component pulls the first connecting rod to rotate in the other direction. The first connecting rod applies force to the lower cantilever, and the lower cantilever flips downward around the front of the mechanism frame, driving the opening and closing cover to approach the vehicle body until the opening and closing cover fits the opening and closing cover setting opening at the front of the vehicle body.

[0020] The technical solution of the present invention is adopted, and the working principle and beneficial effects are as follows:

[0021] The unmanned monorail vehicle cover opening and closing mechanism of the present invention is structured by separately manufacturing a cantilever mechanism and a mechanism frame, and the mechanism frame is fixedly connected to the vehicle body as a basis for setting related components to achieve reliable force transmission. Specifically, the mechanism frame is connected to the inside of the head mask of the vehicle body, and a cover setting opening is set at the front of the head mask. The cover is closed when the cover fits the cover setting opening, and is opened when the cover leaves the cover setting opening. The present invention adopts the method of flipping the cover up to the position above the vehicle body mask to achieve the opening of the cover. A cantilever mechanism is arranged at the front of the mechanism frame, and the cantilever mechanism includes an upper cantilever and a lower cantilever. The front of the upper cantilever and the lower cantilever are respectively movably connected to the opening and closing cover. The upper cantilever is movably connected to the upper position of the front of the mechanism frame, and the lower cantilever is movably connected to the lower position of the front of the mechanism frame. In this way, the upper cantilever and the lower cantilever can rotate relative to the mechanism frame respectively. When the upper cantilever and the lower cantilever rotate to a low position, the upper cantilever and the lower cantilever are located inside the head mask of the vehicle body, and the opening and closing cover is in a closed state at this time. When the upper cantilever and the lower cantilever rotate to a high position, the upper cantilever and the lower cantilever flip upward to a position above the head mask of the vehicle body, that is, the opening and closing cover flips to a position above the head mask. A telescopic component is arranged at the lower part of the mechanism frame, and the mechanism frame serves as a supporting point of the telescopic component, so that when the telescopic component is extended or retracted, a thrust or a pull can be applied. The telescopic component is movably connected to one end of the first connecting rod of the connecting mechanism, and the other end of the first connecting rod is movably connected to the lower cantilever. In this way, when the telescopic component applies thrust to the first connecting rod, the first connecting rod can push or pull the upper cantilever and the lower cantilever to reverse, thereby driving the opening and closing cover to flip. When the telescopic component is extended, it drives the opening and closing cover to flip upward to open, and when the telescopic component is retracted, it drives the opening and closing cover to flip downward to close. The beneficial effects of the structure of the present invention are: 1: Using an electric push rod as a telescopic component to replace the previous gas spring, the output force is stable and is not affected by the temperature. It has an obstacle detection function when pushed up, and the speed and force of rising and falling can be adjusted and can be set by program. 2: The operator can complete the entire operation in the car without having to operate outside the car, which improves convenience. 3: The electric push rod can set the rising and falling speeds, which can ensure that the mechanism opens and closes slowly and smoothly, without strong impact, and protects the opening and closing cover from impact damage.

DETAILED DESCRIPTION

[0029] The following is a further detailed description of the specific implementation of the present invention, such as the shape, structure, mutual position and connection relationship between the various components involved, the function and working principle of each part, etc., through the description of the embodiments with reference to the accompanying drawings:

[0030] As attached Figure 1 -Attached Figure 5As shown, the present invention is an opening and closing mechanism for an opening and closing cover of an unmanned monorail vehicle, a cantilever mechanism 1 is arranged at the front of a mechanism frame 2, the cantilever mechanism 1 comprises an upper cantilever 11 and a lower cantilever 12, the upper cantilever 11 is movably connected to the upper front position of the mechanism frame 2, the lower cantilever 12 is movably connected to the lower front position of the mechanism frame 1, a telescopic component 3 is arranged at the lower part of the mechanism frame 2, the telescopic component 3 is movably connected to one end of a first connecting rod 41 of a connecting mechanism 4, and the other end of the first connecting rod 41 is movably connected to the lower cantilever 12. The above structure proposes an improved technical solution in view of the deficiencies in the prior art. When the structure is set up, the cantilever mechanism 1 and the mechanism frame 2 are separately manufactured, and the mechanism frame 2 is fixedly connected in the vehicle body 9 as a basis for setting related components to achieve reliable transmission of force. Specifically, the mechanism frame 2 is connected to the inside of the head mask of the vehicle body 9, and the front of the head mask is provided with an opening and closing cover setting port 81, and the opening and closing cover 8 is closed when the opening and closing cover 8 is attached to the opening and closing cover setting port 81, and the opening and closing cover 8 is opened when the opening and closing cover 8 is separated from the opening and closing cover setting port 81. The present invention adopts the method of turning the opening and closing cover 8 up to the position above the vehicle body mask of the vehicle body 9 to realize the opening of the opening and closing cover. A cantilever mechanism 1 is arranged at the front of the mechanism skeleton 2, and the cantilever mechanism 1 includes an upper cantilever 11 and a lower cantilever 12. The front parts of the upper cantilever 11 and the lower cantilever 12 are respectively movably connected to the opening and closing covers. The upper cantilever 11 is movably connected to the upper front position of the mechanism skeleton 2, and the lower cantilever 12 is movably connected to the lower front position of the mechanism skeleton 2. In this way, the upper cantilever 11 and the lower cantilever 12 can rotate relative to the mechanism skeleton 2 respectively. When the upper cantilever 11 and the lower cantilever 12 rotate to a low position, the upper cantilever 11 and the lower cantilever 12 are located inside the head mask of the vehicle body 9, and the opening and closing cover 8 is in a closed state at this time. When the upper cantilever 11 and the lower cantilever 12 rotate to a high position, the upper cantilever 11 and the lower cantilever 12 flip upward to a position above the head mask of the vehicle body 9, that is, the opening and closing cover 1 flips to a position above the head mask. A telescopic component 3 is arranged at the lower part of the mechanism skeleton 2, and the mechanism skeleton 2 serves as a supporting point of the telescopic component, so that when the telescopic component 3 is extended or retracted, a thrust or a pull can be applied. The telescopic component 3 is movably connected to one end of the first connecting rod 41 of the connecting mechanism 4, and the other end of the first connecting rod 41 is movably connected to the lower cantilever 12, so that when the telescopic component 3 applies a thrust to the first connecting rod 41, the first connecting rod 41 can push or pull the upper cantilever 11 and the lower cantilever 12 to reverse, thereby driving the opening and closing cover 1 to flip. When the telescopic component is extended, it drives the opening and closing cover to flip upward to open, and when the telescopic component 3 is retracted, it drives the opening and closing cover 8 to flip downward to close. The beneficial effects of the structure of the present invention are: 1: Using an electric push rod as a telescopic component to replace the previous gas spring, the output force is stable and is not affected by the temperature. It has an obstacle detection function when pushed upward, and the speed and force of rising and falling can be adjusted and can be set by program. 2: The operator can complete the entire operation in the vehicle without having to operate outside the vehicle, thereby improving convenience.3: The electric push rod can set the rising and falling speeds, which can ensure that the mechanism opens and closes slowly and smoothly without strong impacts, and protects the opening and closing cover from being damaged by impacts. The unmanned monorail vehicle described in the present invention has a simple structure, and can realize automatic opening and closing of the opening and closing cover without changing the vehicle body mask and the opening and closing cover. The output force is stable and is not affected by the temperature. It ensures that the mechanism opens and closes slowly and smoothly without strong impacts, and protects the opening and closing cover from being damaged by impacts, and realizes the synchronous locking and unlocking actions of the electric lock.

[0031] The telescopic rod 31 of the telescopic part 3 is movably connected to one end of the second connecting rod 42 of the connecting mechanism 4, and the other end of the second connecting rod 42 is movably connected to the front part of the mechanism frame 2. In the above structure, when the telescopic part is in motion, the telescopic rod 31 realizes a telescopic action, thereby pushing or pulling the first connecting rod 41, and the second connecting rod 42 connects the telescopic rod 31 and the mechanism frame 2. On the one hand, the telescopic rod 31 of the telescopic part 3 is constrained to avoid excessive swing of the telescopic part 3 when force is applied. On the other hand, the connection of the second connecting rod 42 does not affect the telescopic movement of the telescopic rod 31 of the telescopic part 3, and does not hinder the control of the cantilever mechanism. At the same time, the structural setting of the upper cantilever 11 can be set according to the connection method of the lower cantilever, or the telescopic part, the first connecting rod, and the second connecting rod can be set, so as to realize the automatic control of the upper cantilever and the lower cantilever respectively.

[0032] The upper cantilever 11 of the cantilever mechanism 1 is a bent structure, and the upper cantilever 11 includes a first section 111, a second section 112, and a third section 113. The first section 111 and the second section 112 form a right angle or an obtuse angle, and the second section 112 and the third section 113 form an obtuse angle. In the above structure, the first section 111, the second section 112, and the third section 113 of the upper cantilever are an integrated structure with high overall strength, and the above bending structure enables the cantilever mechanism 1 to be retracted over a relatively short distance by the telescopic component 2, and the cantilever mechanism can be flipped over a relatively large range.

[0033] The lower cantilever 12 of the cantilever mechanism 1 is a bent structure, and the lower cantilever 12 includes a lower cantilever first section 121, a lower cantilever second section 122, and a lower cantilever third section 123. The lower cantilever first section 121 and the lower cantilever second section 122 are at a right angle or an obtuse angle, and the lower cantilever second section 122 and the lower cantilever third section 123 are at an obtuse angle. In the above structure, the lower cantilever first section 121, the lower cantilever second section 122, and the lower cantilever third section 123 are an integrated structure with high overall strength, and the above bending structure enables the cantilever mechanism 1 to be able to achieve a larger range of flipping of the cantilever mechanism through the telescopic component 2 being telescopically extended over a short distance.

[0034] The front ends of the upper cantilever 11 and the lower cantilever 12 of the cantilever mechanism 1 are respectively connected to the opening and closing cover 8. In the above structure, the cantilever mechanism flips to drive the opening and closing cover to flip open or close.

[0035] The end of the upper suspension first section 111 of the upper cantilever 11 is movably connected to the front upper position of the mechanism frame 2 through a pin, and the lower suspension first section 111 of the lower cantilever 12 is movably connected to the front lower position of the mechanism frame 1. One end of the first connecting rod 13 connected to the lower cantilever 12 is movably connected to the lower cantilever second section 122 and the lower cantilever third section 123 through a pin. The upper suspension third section 113 of the upper cantilever 11 and the lower suspension third section 123 of the lower cantilever 12 are movably connected to the connecting seat 13 through a pin, respectively, and the connecting seat 13 is fixedly connected to the inner side of the opening and closing cover 8. The above structure realizes the movably connected related parts through multiple pins, which not only ensures that the related connections are reliably connected, but also can realize rotation and flexible rotation.

[0036] The telescopic component 3 is an electric push rod, and the telescopic component 3 is connected to the control box 5 through the wire 6, and the control box 5 is connected to the electric lock 7 through the wire 6. The electric lock 7 includes an electric lock body 7, and a small motor is arranged in the electric lock body 7, and the driving teeth of the small motor engage the lock tongue teeth on the lock tongue. In the above structure, the control of the electric lock is realized by the control box to the small motor of the electric lock. When the structure is set, in order to ensure the stability of the opening and closing of the opening and closing cover, two sets of unmanned monorail vehicle opening and closing cover opening and closing mechanisms need to be symmetrically arranged, and the two sets of unmanned monorail vehicle opening and closing cover opening and closing mechanisms need to act synchronously. The control of the electric lock is realized by the control box to the small motor of the electric lock, so that the synchronous control can be reliably realized and the control accuracy can be improved.

[0037] The electric lock 7 is arranged near the telescopic component. The telescopic component is an electric push rod. The electric push rod is a screw sleeve structure, and the screw is connected to the driving gear of a small motor through the tooth meshing, and the small motor is fixed in the electric lock body. The small motor rotates to realize the rotation of the lead screw, and the rotation of the screw drives the sleeve to rotate. One end of the sleeve is connected to the screw, and the sleeve is connected to the first connecting rod. The sleeve will not rotate, so the entire telescopic component can be extended and retracted when the screw rotates in different directions. The function of the electric lock is to achieve the locking and unlocking of the screw through the extension and retraction of the lock tongue when the screw stops rotating. The lock tongue is inserted into the screw to achieve locking, and the lock tongue leaves the screw to achieve unlocking. In this way, it is ensured that the telescopic component will not be extended and retracted at will, and the opening or closing state of the opening and closing cover is reliable.

[0038] The present invention also relates to a control method for an opening and closing mechanism of an unmanned monorail vehicle opening and closing cover, which has simple steps and can realize automatic opening and closing of the opening and closing cover without modifying the vehicle body mask and the opening and closing cover, has a stable output force that is not affected by the temperature, ensures that the mechanism opens and closes slowly and smoothly without strong impact, protects the opening and closing cover from damage by impact, and realizes synchronous locking and unlocking of the electric lock.

[0039] The steps of the control method of the opening and closing mechanism of the opening and closing cover of the unmanned monorail vehicle are as follows:

[0040] S1. When the opening and closing cover 8 needs to be controlled to flip up and open, the control box 5 controls the telescopic part 3 to extend, and the telescopic part 3 pushes the first connecting rod 13 to rotate in one direction. The first connecting rod 13 applies force on the lower cantilever 12, and the lower cantilever 12 flips upward around the front of the mechanism frame 2, driving the opening and closing cover 8 to leave the opening and closing cover setting opening 81 at the front of the vehicle body 9, until the opening and closing cover 8 flips upward to the position above the vehicle body 9; S2. When the opening and closing cover 8 needs to be controlled to flip down and close, the control box 5 controls the telescopic part 3 to retract, and the telescopic part 3 pulls the first connecting rod 13 to rotate in the other direction, and the first connecting rod 13 applies force on the lower cantilever 12, and the lower cantilever 12 flips downward around the front of the mechanism frame 2, driving the opening and closing cover 8 to approach the vehicle body 9, until the opening and closing cover 8 fits the opening and closing cover setting opening 81 at the front of the vehicle body 9.

[0041] The opening and closing mechanism of the opening and closing cover of the unmanned monorail vehicle described in the present invention is respectively made of a cantilever mechanism 1 and a mechanism frame 2. The mechanism frame 2 is fixedly connected to the vehicle body 9 as a basis for setting related components to achieve reliable transmission of force. Specifically, the mechanism frame 2 is connected to the inside of the head mask of the vehicle body 9, and the opening and closing cover setting opening 81 is set at the front of the head mask. The opening and closing cover 8 is closed when it fits the opening and closing cover setting opening 81, and the opening and closing cover 8 is opened when it leaves the opening and closing cover setting opening 81. The present invention adopts the method of turning the opening and closing cover 8 up to the position above the vehicle body mask of the vehicle body 9 to achieve the opening of the opening and closing cover. A cantilever mechanism 1 is arranged at the front of the mechanism skeleton 2, and the cantilever mechanism 1 includes an upper cantilever 11 and a lower cantilever 12. The front parts of the upper cantilever 11 and the lower cantilever 12 are respectively movably connected to the opening and closing covers. The upper cantilever 11 is movably connected to the upper front position of the mechanism skeleton 2, and the lower cantilever 12 is movably connected to the lower front position of the mechanism skeleton 2. In this way, the upper cantilever 11 and the lower cantilever 12 can rotate relative to the mechanism skeleton 2 respectively. When the upper cantilever 11 and the lower cantilever 12 rotate to a low position, the upper cantilever 11 and the lower cantilever 12 are located inside the head mask of the vehicle body 9, and the opening and closing cover 8 is in a closed state at this time. When the upper cantilever 11 and the lower cantilever 12 rotate to a high position, the upper cantilever 11 and the lower cantilever 12 flip upward to a position above the head mask of the vehicle body 9, that is, the opening and closing cover 1 flips to a position above the head mask. A telescopic component 3 is arranged at the lower part of the mechanism skeleton 2, and the mechanism skeleton 2 serves as a supporting point of the telescopic component, so that when the telescopic component 3 is extended or retracted, a thrust or a pull can be applied. The telescopic component 3 is movably connected to one end of the first connecting rod 41 of the connecting mechanism 4, and the other end of the first connecting rod 41 is movably connected to the lower cantilever 12, so that when the telescopic component 3 applies a thrust to the first connecting rod 41, the first connecting rod 41 can push or pull the upper cantilever 11 and the lower cantilever 12 to reverse, driving the opening and closing cover 1 to flip. When the telescopic component is extended, it drives the opening and closing cover to flip upward to open, and when the telescopic component 3 is retracted, it drives the opening and closing cover 8 to flip downward to close. The beneficial effects of the structure of the present invention are: 1: Using an electric push rod as a telescopic component to replace the previous gas spring, the output force is stable and is not affected by the temperature. It has an obstacle detection function when pushed up, and the speed and force of rising and falling can be adjusted and can be set by program. 2: The operator can complete the entire operation in the vehicle without having to operate outside the vehicle, thereby improving convenience. 3: The electric push rod can set the rising and falling speeds, which can ensure that the mechanism opens and closes slowly and smoothly without strong impact, protecting the opening and closing cover from impact damage.

[0042] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
