The electronic signals are more accurate and stable, the stable operation of the vehicle can be effectively ensured, and meanwhile, the effects of energy conservation and emission reduction can be achieved.

However, the existing electric control pedal has the following defects:

1. since the principle of the electric control pedal is completely different from that of the conventional hydraulic pedal, and the characteristic of the pedal force is also different from that of the conventional hydraulic pedal, it is difficult for a driver who is used to the conventional hydraulic pedal to adapt to the electric control pedal at a glance.

2. The electric control pedal returns to the initial state (corresponding to the vehicle being in a static state) under the action of the two groups of springs, and when the two groups of springs cause inconsistent resilience force due to aging or manufacturing errors, the pedal cannot completely return, so that the vehicle moves forwards and backwards uncontrollably.

3. The pedals of a track-type vehicle can integrally control the forward and backward movement of the vehicle, and when the pedals are stepped forward, the vehicle moves forward, and when the pedals are stepped backward, the vehicle moves backward. Due to the structural problem, a driver cannot easily perceive the middle node of the pedal (namely the position of the pedal when the corresponding vehicle is static), and certain influence is generated on the fine operation of the tracked vehicle.

Detailed Description

The invention is further illustrated by the following specific examples:

example 1

As shown in fig. 1 and 2, an electronic control pedal includes a rotary base 100, a pedal 200, an operating rod 300, an electronic control assembly 400, and a damper 500. The pedal 200 is coupled to the rotating base 100. The operation lever 300 is connected to the pedal 200.

As shown in fig. 3, 5 and 6, the rotating base 100 includes a base 110, a rotating member 120, a front compression spring 130, a rear compression spring 131 and a protective shell 140.

The base 110 is provided with a receiving cavity 111 with an open top. The rotating member 120 is disposed in the accommodating cavity 111, the rotating member 120 is T-shaped, and includes a front horizontal segment 121, a rear horizontal segment 122, a vertical segment 123 with a top connected to the front horizontal segment 121 and the rear horizontal segment 122, and a rotating shaft portion 124 connected to the vertical segment 123, wherein the extending direction of the rotating shaft portion 124 is perpendicular to the rotating member 120. The top surface of the rotating member 120 is higher than the top opening of the accommodating cavity 111.

The two ends of the rotating shaft 124 are respectively pivoted to the sidewalls of the two sides of the accommodating cavity 111 of the base 110, so that the rotating element 120 can rotate relative to the base 110.

One end of the front compression spring 130 is fixed to the bottom surface of the accommodating cavity 111, and the other end is fixed to the bottom surface of the front horizontal section 121. One end of the rear compression spring 131 is fixed to the bottom surface of the accommodating cavity 111, and the other end is fixed to the bottom surface of the rear horizontal section 122. The front and rear compression springs 130 and 131 are used to provide elastic feedback when the driver steps on the pedal, and elastically restore the rotary member 120 to a centered position, i.e., a position in which the front and rear

horizontal sections

121 and 122 are in a horizontal state, when the driver releases the pedal.

The front compression spring 130 and the rear compression spring 131 are each composed of one large spring 132 and a small spring 133 provided in the large spring 132. With such a structure, when one of the front compression spring 130 or the rear compression spring 131 is damaged, that is, one of the small spring 132 or the large spring 133 is damaged, the remaining small spring 133 or the large spring 132 can still provide a resilience force to offset the pressure of the intact compression spring on the other side, so that the rotation amplitude of the pedal is reduced. The pedal 200 is prevented from directly rotating to the tail end of the stroke under the elastic force of a perfect pressure spring on one side of the pedal, so that the vehicle is prevented from suddenly and violently accelerating/retreating, and the safety is improved.

The protective shell 140 is fixed on the top surface of the rotating member 120 and covers the accommodating cavity 111 on the base 110, so that the accommodating cavity 111 becomes a closed space, and thus, the device failure caused by the intrusion of external dust and moisture into the accommodating cavity 111 is effectively avoided.

As shown in fig. 1 and 2, a connection block is provided on the top of the protective case 140, and the pedal 200 is fixed to the connection block by a connection member 210. The side profile of the connector 210 is triangular, including a horizontal mounting surface, a vertical mounting surface, and an angled mounting surface. The pedal 200 is fixed on the inclined installation surface, so that the pedal 200 has a certain inclination angle relative to the horizontal plane when in rest, and a driver can conveniently step on the pedal.

The operating lever 300 is fixed to the vertical mounting surface and extends in an outward tilting manner. The operation lever 300 can be interlocked with the pedal 200. The driver may select one of the lever 300 or the pedal 200 for control.

As shown in fig. 1 and 5, the electronic control assembly 400 includes a sensing transmitting element linked with the rotating shaft portion 124 and a sensing receiving element cooperating with the sensing transmitting element. Specifically, the sensing and transmitting element is a cylinder 410, and the cylinder 410 is located outside the rotating base 100 and connected to one end of the rotating shaft 124. The sensing receiving element is a sensor 420, which is located on the side wall of the rotary base 100 corresponding to the side of the magnetic cylinder. The sensor 420 has a sensing surface proximate to the cylinder. When the user steps on the pedal, the rotating shaft portion 124 rotates in linkage with the magnetic cylinder 410, and the sensor 420 senses the magnetic force change when the magnetic cylinder 410 rotates, and outputs a corresponding control signal to an ECU (vehicle computer) of the vehicle to control the working state of the engine. Thereby achieving an electrically controlled operation of the vehicle.

Obviously, the electronic control assembly 400 is not limited to the above structure, and may also directly detect the rotation angle of the rotating shaft through an angle sensor, or replace the magnetic cylinder in this embodiment with an optoelectronic device, and replace the electromagnetic sensor in this embodiment with a photoelectric sensor.

As shown in fig. 1, the damper 500 is in the shape of a rod and is located outside the rotating base 100, one end of the damper is hinged to the base 110, and the other end of the damper is hinged to the bottom of the front end of the pedal 200. The damper 500 functions to provide a certain damping when the driver steps on the pedal 200, so that the feeling of the pedal 200 is consistent with that of a conventional hydraulic pedal, and the driver who is used to the conventional hydraulic pedal can quickly start to use the vehicle with the electrically controlled pedal.

As shown in fig. 3 and 4, a piston cylinder 125 is disposed in the vertical section of the rotating member 120, and the piston cylinder 125 includes a cylinder 126, an elastic member 127 disposed in the cylinder 126, and a rod 128 capable of extending from the bottom of the cylinder 126. The bottom of the accommodating cavity 111 is provided with an arc concave surface 112 at a position corresponding to the bottom of the rod body 128, and a depression 113 is arranged at the lowest point of the concave surface 112. When the rotary member 120 is in the centered position, the recess 113 is located directly below the rod 128. The resilient member 127 biases the rod downwardly so that the bottom end of the rod 128 is always held against the concave surface 112.

When the driver releases the pedal, the rod 128 slides to the lowest point depression 113 under the guiding action of the concave surface and the biasing action of the elastic member 127. Leaving the rotating member 120 in the centered position. The phenomenon that the rotating member 120 cannot keep the centered position due to inconsistent elastic forces of the front compression spring 130 and the rear compression spring 131 is avoided. Preventing uncontrolled forward or backward movement of the vehicle after the pedal 200 is released.

Meanwhile, due to the structure, an obvious retarding force can be generated when the pedal 200 rotates to the middle position, the perception of a driver is improved, and the driver can control the vehicle more accurately.

The elastic member 127 is a spring provided in the cylinder. Of course, the present invention is not limited to the use of piston cylinder 125, and it is also possible to provide a gas cylinder that utilizes gas compressible properties to bias rod body 128 downward against a recessed surface.

Example 2

Embodiment 2 also provides an electric control pedal, as shown in fig. 7 and 8, which is substantially identical to the electric control pedal of embodiment 1, with the main difference that: the damper 500 in embodiment 2 is not disposed outside the rotating base 100, but disposed in the accommodating cavity 111 of the rotating base 100, and one end of the damper 500 is hinged to one side of the rear horizontal section 122 of the rotating member 120, and the other end is hinged to the wall of the accommodating cavity of the rotating base 100. The end hinged with the rotating part 120 is higher, and the end hinged with the wall of the accommodating cavity is lower. The damper 500 functions in accordance with the damper 500 of embodiment 1, and is designed to provide a certain damping force to the pedal depression of the driver, so that the foot feeling of the pedal 200 is consistent with that of the conventional hydraulic pedal. The damper 500 is disposed in the receiving cavity 111 of the rotary base 100 to prevent the damper 500 from being damaged or degraded by dust and moisture. Or be damaged by impact from an external force. Has higher reliability and service life than that of the embodiment 1. Since the space of the accommodation chamber 111 is narrow, the rotation shaft portion 124 is provided with an escape recess at a position close to the damper 500. So as to avoid the damper from being rubbed with the rotating shaft part.

Example 3

As shown in fig. 9, embodiment 3 provides an electric control pedal module including two electric control pedals arranged in parallel on the basis of embodiment 1 or 2. The sensor 420 is disposed between the two electronic control pedals and is covered by a cover 600 disposed between the two electronic control pedals, and an interface of the sensor 420 protrudes downward. This enables a more compact structure and effectively protects the sensor 420 from the external environment.

Example 4

As shown in fig. 10, embodiment 4 provides an electronic control pedal module including two electronic control pedals arranged in parallel on the basis of embodiment 1 or 2. Unlike embodiment 3, the sensor 420 in embodiment 4 is disposed on the side of the two electrically controlled pedals, i.e., on both sides of the electrically controlled pedals, and the sensor interface in embodiment 4 extends in the horizontal direction.
