Description

Technical Field

[0001] The utility model relates to the technical field of electric pedals, in particular to an electric pedal driving device for a new energy vehicle. Background Art

[0002] The electric step is an automatically retractable electric step for cars, providing convenient services for getting on and off high-chassis cars. At present, most new energy vehicles with higher chassis will be equipped with electric steps as an option or directly installed.

[0003] The technical solution disclosed in the Chinese patent with authorization announcement number CN215706010U drives the electric push rod to work, so that the output end of the electric push rod is recovered, so that the support arm moves up together with the output end of the electric push rod. Since the length of the support arm remains unchanged, the support arm will flip, so that the support rod will also flip. When the support arm reaches the horizontal position, the electric push rod stops working. At this time, the shell is in a horizontal state, and the support arm, the support rod and the fixed rod form a triangle to support the shell, and the rotation of the gear drives the pulley to rotate. When the two pulleys rotate, they will also drive the belt to rotate, so that the belt drives the extension plate to extend out of the shell through the fixedly connected connecting block, thereby extending the fixed plate.

[0004] However, the device still has some shortcomings: since the fixing rod is provided in the device, the fixing rod will reduce the minimum ground clearance between the vehicle chassis and the ground, and the fixing rod is easily knocked crooked or even broken during off-roading.

DETAILED DESCRIPTION

[0022] like Figure 1-Figure 3 As shown, the utility model proposes a new energy vehicle electric pedal drive device, including a mounting frame 1, a pedal 7, a pressure detection component and a driving component. The mounting frame 1 is provided with an ear plate 2, and the ear plate 2 is provided with a waist-shaped groove. The mounting frame 1 is rotatably connected to two rotating shafts A3, the two rotating shafts A3 are parallel to each other, and splines 301 are provided on both rotating shafts A3. Both ends of the connecting rod 4 are provided with shaft holes, and the peripheral side of one side of the shaft hole is provided with a spline groove 401 connected thereto, and the rotating shaft A3 passes through the shaft hole provided with the spline groove 401, and the spline 301 is inserted into the spline groove 401 and meshed therewith. The other ends of the two groups of connecting rods 4 are respectively rotatably connected to a rotating shaft B5, and the two rotating shafts B5 are simultaneously rotatably connected to the same bottom plate 6. The pedal 7 is connected to the bottom plate 6, and the pedal 7 is connected to the anti-slip plate 8. The pressure detection component includes a plurality of pressure sensors 9. Each pressure sensor 9 is connected to the pedal 7, and the detection end of the pressure sensor 9 abuts against the bottom surface of the anti-slip plate 8, and the pressure sensor 9 is electrically connected to the control component. The driving assembly includes a motor 15. Worm gears 10 are arranged on both rotating shafts A3, the mounting frame 1 is rotatably connected to the rotating shaft C11, the rotating shaft C11 is connected to two worms 12, the two groups of worms 12 are respectively meshed and connected with the worm gears 10 on the corresponding sides, the motor 15 is connected to the mounting frame 1, the rotating shaft C11 is connected to the gear A13, the output end of the motor 15 is connected to the gear B14, the gear A13 and the gear B14 are meshed, and the outer diameter of the gear B14 is smaller than the outer diameter of the gear A13, the motor 15 drives the two groups of connecting rods 4 to rotate synchronously in the same direction, so that the horizontal angle of the bottom plate 6 is kept constant during the action, and the driving assembly is electrically connected to the control assembly, so as to automatically control the bottom plate 6 and the pedal 7 to retract when the pressure detection assembly detects that the pressure on the anti-slip plate 8 disappears. It also includes an induction switch and an electric control switch linked to the door, and the induction switch is electrically connected to the control assembly and the driving assembly.

[0023] In this embodiment, the mounting plate is fixed to the bottom of the chassis of the vehicle body, and then the circuit is connected. When the door is opened, the induction switch feeds back the door opening signal to the control component, and the control component controls the motor 15 to start. The motor 15 drives the gear B14 to rotate, and then drives the gear A13 and the rotating shaft C11 to rotate. Due to the differential structure of the gear A13 and the gear B14, the rotating shaft C11 obtains a larger torque, thereby providing a stronger supporting force for the pedal. The rotation of the rotating shaft C11 drives the rotating shaft A4 to rotate through the worm gear structure, and then drives the connecting rod 5 to rotate, so that the pedal 7 is lowered from the storage state and extends obliquely upward for an appropriate distance. When a person steps on the anti-skid plate 8, the pressure sensor 9 detects a pressure signal, which is fed back to the controller. The controller keeps the pedal 7 extended and motionless. After the person's foot leaves the anti-skid plate 8, the pressure signal disappears. At this time, the motor 15 automatically starts and retracts the pedal 7 after the set interval time is reached. Since the movement path of the pedal 7 is first obliquely downward and then obliquely upward, and the body of the vehicle limits the position of the legs and feet, there will be no accidental clamping when the pedal 7 is recovered. The retracted pedal 7 remains parallel to the vehicle chassis. Since the connecting rod is almost parallel to the chassis at this time, the pedal 7 will not affect the minimum ground clearance of the vehicle chassis.

[0024] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
