As shown in fig. 1 to 7, the utility model provides a mechanical pedal for passengers to get on or off the bus.
The mechanical step comprises a box body 1, a step panel 2, a release lever 3 and an energy storage driving mechanism 4.
The front end of the box body 1 is provided with an opening 12, so that the inner cavity 11 of the box body 1 is communicated with the external space.
The pedal plate 2 is slidably mounted in the inner cavity 11 of the box body 1, can slide forward to extend out of the box body 1 through the opening 12, and can slide backward to be retracted into the box body 1.
The release lever 3 is mounted on the step panel 2, and is provided with a pedal 31 at one end.
The energy storage driving mechanism 4 is arranged in the inner cavity 11 of the box body 1.
As shown in fig. 1 to 4, when the mechanical step is in a retracted state, the step panel 2 is retracted into the case 1, and the release lever 3 locks the energy storage driving mechanism 4.
When the pedal 31 of the release lever 3 is depressed, the release lever 3 releases the charging drive mechanism 4, i.e., the release lever 3 stops restraining the charging drive mechanism 4. After the release, the potential energy in the energy storage driving mechanism 4 drives the tread plate 2 to move forward and extend out of the box body 1, as shown in fig. 5, the mechanical step is in an unfolded state, and the extended tread plate 2 is used as a step for passengers to tread when getting on or off the vehicle.
The energy storage driving mechanism 4 is of a mechanical structure, the mechanical stepping is unfolded and retracted in a mechanical mode, the structure is simple, an electric power system or a hydraulic system is not required to be equipped, the device is not easy to damage, the maintenance is easy, and the problems that the existing stepping device is complex in structure and high in failure rate are solved.
To embody the driving of the pedal panel 2, as shown in fig. 7, the energy-storage driving mechanism 4 includes a gas spring 41, a driving gear 42, and a push rod 43.
Two driving gears 42 are provided and are installed on the bottom surface of the inner cavity 11 of the box body 1. The two drive gears 42 are intermeshed for the transmission of each other.
The push rod 43 is used as a connecting rod, and two ends of the push rod are respectively hinged on the driving gear 42 and the tread plate 2. The push rods 43 are provided in two numbers, respectively located at the left and right sides, and one push rod 43 is connected to each of the driving gears 42, so that both the driving gears 42 can drive the pedal panel 2 through the corresponding push rods 43.
One end of the gas spring 41 is hinged with the box body 1, and the other end is hinged with one of the driving gears 42. The hinge point of the gas spring 41 to the drive gear 42 is located outside the axle of the drive gear 42.
The drive gear 42 is provided with a set screw 44, the set screw 44 rotates synchronously with the drive gear 42, and the set screw 44 is positioned inside the axle of the drive gear 42.
The release lever 3 has a pedal 31 at one end and a stopper portion 32 at the other end.
As shown in fig. 2 to 3, when the mechanical step is in a retracted state, the step panel 2 is retracted into the box body 1, the push-pull rod of the gas spring 41 is retracted, the gas sealed in the gas spring 41 is compressed by the push-pull rod, the limiting portion 32 of the release lever 3 is hooked on the set screw 44, and the set screw 44 is prevented from moving backwards, so that the gas spring 41 cannot push the driving gear 42 to rotate, and the energy storage driving mechanism 4 is locked.
The pedal 31 on the release lever 3 is stepped to lift the limiting part 32 at the other end of the release lever 3, the set screw 44 loses the limiting function of the limiting part 32, and the compressed gas in the gas spring 41 releases the potential energy therein to push the push-pull rod to extend.
The push-pull rod extending from the gas spring 41 pushes the driving gear 42 connected with the gas spring to rotate, and the other driving gear 42 synchronously rotates through transmission between the gears.
Since the set screw 44 is located inside, it moves rearward as the drive gear 42 rotates. Since the push rod 43 is connected to the outside, it moves forward with the rotation of the driving gear 42, pushing the step panel 2 forward out of the case body 1, and making the mechanical step change to the unfolded state.
When the tread plate needs to be retracted, the tread plate 2 is manually pushed back into the box body 1, all the components of the energy storage driving mechanism 4 move reversely, the set screw 44 returns to the initial position when the mechanical step is in the retracted state, the limiting part 32 of the release lever 3 hooks the set screw 44, the set screw 44 is prevented from moving backwards, and the energy storage driving mechanism 4 is locked.
The gas spring 41 is driven by the two driving gears 42 to enable the push rods 43 on the two sides to synchronously push the pedal plate 2 to extend, the stress on the two sides of the pedal plate 2 is uniform, the pedal plate can keep stable when extending and retracting, and one side of the pedal plate cannot be inclined and clamped in the box body 1. Simultaneously, gear drive operation is more stable, when avoiding energy storage actuating mechanism 4 to release, pushes out tread board 2 fast, produces the collision between the structure, perhaps impairs operating personnel.
In order to raise the stopper portion 32, the release lever 3 is hinged at the middle on the bottom surface of the tread panel 2 as shown in fig. 6.
The pedal 31 is located at the front end, the pedal 31 is stepped downwards, the release rod 3 serves as a lever, the limiting portion 32 located at the rear end can be easily lifted, and the release operation of the energy storage driving mechanism 4 is more convenient.
In order to keep the release lever 3 locked to the charging drive mechanism 4 when the pedal 31 is not depressed, a lock spring 5 is installed between the rear portion of the release lever 3 and the bottom surface of the pedal panel 2.
The lock spring 5 is a compression spring and is always in a deformed state, and the generated elastic force pushes the rear portion of the release lever 3 downward to press the stopper portion 32 against the drive gear 42, so that the stopper portion 32 can be kept hooked on the set screw 44.
When the energy storage driving mechanism 4 is released, the pedal 31 is stepped to overcome the elastic force of the locking spring 5, and the limit portion 32 is lifted.
After the energy storage driving mechanism 4 is released, the limiting portion 32 needs to be lifted first, so that the locking state can be recovered. In order to improve the convenience of operation, as shown in fig. 6, the edge of the rear end of the release lever 3 is provided with a chamfer 33.
During the pushing back of the pedal plate 2 into the case 1, the lock spring 5 presses the stopper 32 against the driving gear 42, and the set screw 44 moves forward and abuts against the edge of the rear end of the release lever 3. Since the rear end edge of the release lever 3 has the chamfer 33, the set screw 44 contacts the chamfer 33 and slides along the chamfer 33 onto the bottom surface of the release lever 3, thereby lifting up the rear portion of the release lever 3, eventually passing over the stopper portion 32, returning the stopper portion 32 to the rear side of the set screw 44, hooking the set screw 44, and locking the stored energy driving mechanism 4.
In the process, the pedal 31 is not needed to be stepped, and the pedal plate 2 is only needed to be pushed into the box body 1, so that the operation is convenient.
In order to improve the locking firmness of the energy storage driving mechanism 4, two set screws 44 are symmetrically arranged, and one set screw 44 is arranged on each driving gear 42.
Two limiting parts 32 are also symmetrically arranged and are respectively positioned at the left side and the right side of the rear end of the release lever 3. Each of the stoppers 32 hooks a corresponding one of the set screws 44 when locking the stored energy drive mechanism 4.
In order to increase the moving distance of the push rods 43, swing arms 45 are arranged on the outer sides of the driving gears 42, and the push rods 43 are hinged on the corresponding swing arms 45.
The swing arm 45 has the same rotation angle as the corresponding drive gear 42, but the outer end of the swing arm 45 moves a greater distance. The push rod 43 is hinged on the swing arm 45, which can increase the moving distance of the push rod 43, so that the push rod 43 can push out and pull back the pedal panel 2 completely.
In order to ensure the smoothness of the movement of the tread plate 2, rollers 21 are mounted on both sides of the tread plate 2, and the rollers 21 are mounted on guide rails 13 arranged in the inner cavity 11.
To facilitate the depressing operation of the pedal 31, the pedal 31 extends forward to the front side of the pedal panel 2.
The pedal 31 extends forward and has no structural shield above it, facilitating the stepping of the user.
The pedal panel 2 is retracted in the box body 1, and when the mechanical pedal is in a retracted state, the pedal 31 extends out of the box body 1 so as to perform a pedal operation.
