All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1-4, the present invention provides a technical solution: an electronic brake with initial resistance comprises a base 1 and a pedal 2, wherein the pedal 2 is obliquely arranged, the lower end of the pedal 2 is hinged to the base 1, and the bottom surface of the pedal 2 is connected with the base 1 through a torsion spring 3; the bottom surface of the upper end of the pedal 2 is hinged with a connecting shaft 4, the tail end of the connecting shaft 4 is rotatably provided with a roller 5, and a resistance slope 6 is arranged on the base 1 corresponding to the position of the roller 5.

Furthermore, the torsion spring 3 is expanded to be a V-shaped structure, one side of the torsion spring is attached and fixed on the base 1, and the other side of the torsion spring is fixedly connected with the bottom surface of the pedal 2.

Furthermore, the inclined plane of the resistance slope 6 is arranged obliquely upwards along the direction far away from the pedal 2, and the lower end of the resistance slope 6 is longitudinally cut off to form a step section 7 abutted against the roller 5.

Further, the roller 5 can rotate along the hinge point of the connecting shaft 4, and the roller 5 can roll on the surfaces of the base 1 and the resistance slope 6.

The working principle is as follows:

before the brake, operator's foot 8 places on footboard 2, for the lax state can, this moment gyro wheel 5 is in 6 lower extreme positions of resistance slope just, with 7 butts of step section, the resistance of step section 7 provides the pressure when foot 8 places naturally.

During braking, the foot part 8 presses the pedal 2, the roller 5 passes through the step section 7 under the pressure action of the pedal 2 and then moves upwards along the inclined plane of the resistance slope 6, in the process of moving upwards, the braking resistance is mainly the elastic force of the torsion spring 3, and the foot part 8 can perform braking action and keep braking action with small force.

After braking, the foot part 8 is lifted, the pedal 2 is lifted under the elastic force of the torsion spring 3, the roller 5 slides down along the resistance slope 6 to the lower part of the step section 7 to stop, and the foot part 8 can be continuously and naturally placed on the pedal 2.

Neither can the original purpose of the electronic brake be negatively influenced by the people, nor can the phenomenon of brake be generated, the problem that the brake is generated by an operator unconsciously is effectively solved, and the comfort level of a driver is improved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
