Description

Technical Field

[0001] The utility model relates to an electronic pedal, in particular to a modular electronic pedal. Background Art

[0002] At present, in order to adapt to different working conditions, more and more types of cranes are being developed, and various types of engines are being selected. In view of the different requirements of the electronic pedal control functions of the driving cab and the control room of the lifting operation, if electronic pedals with different functions and different engines are directly selected to realize the throttle electronic acceleration function, crane slewing switch type brake, crane slewing electric proportional brake, auxiliary reel enable and other configuration requirements, the pedal styles are diverse and messy, and the appearance, color, size, style, etc. are not uniform. Or, if new electronic pedals with different functions are developed, the mold investment is large, resulting in high development costs and waste of resources.

[0003] The layout of the electronic pedals in the existing control room, such as Figure 1 As shown, different styles of electronic pedals are used, and the styles are not uniform. If different engines are used, there will be other differences in the pedal types. Different engines will require different pedal signals, and generally different electronic pedals are matched. This type of electronic pedal cannot well meet the different configuration requirements of different customers and the requirements of different engine signal outputs, and is not conducive to the standardization of the electronic pedal's appearance, size, style, and installation holes. If multiple electronic pedals are developed to meet the needs of different output signals, the mold investment will be large, resulting in high development costs and waste of resources.

[0004] The emergence of the above problems results in the electronic pedal being unable to meet the different configuration requirements of different customers and the requirements of different engine signal outputs, which is not conducive to the standardization of the appearance and installation holes of the electronic pedal. Utility Model Content

[0005] The purpose is to solve the unified problems of the appearance, size, style and installation holes of the electronic pedals in the crane's cab and operating room. By carrying out functional and structural classification under the concept of "modularization", the production development cycle can be shortened and the cost of repeated mold investment can be reduced. At the same time, the differentiation of vehicle control can be achieved by changing a certain module of the electronic pedal, while meeting the functional requirements of users in different regions and different engine configurations.

[0006] Therefore, an electronic pedal is provided to replace the original electronic pedals of various structures and shapes. For pedals with different signal requirements, it is only necessary to replace the corresponding type of sensor to achieve electronic throttle acceleration for different engines, with signal output in two control modes: voltage-electric proportional and switch-type. This can meet the requirements of throttle acceleration functions of different engines, crane slewing switch-type brakes, crane slewing electric proportional brakes, auxiliary reel enable and other configurations, and achieve the standardization of the shape, size, style and installation hole position of the electronic throttle pedals in the crane's getting on and off the cab and the control room.

[0007] Cab: The driver's cab used to drive construction machinery and equipment vehicles, mainly for driving.

[0008] Control room: An operating room used for operating construction machinery and equipment vehicles, mainly for lifting operations.

[0009] Modularity: refers to the use of certain design methods to design multiple modules, and to achieve different configurations by combining different modules.

[0010] Electronic accelerator pedal: also called electronic accelerator, engine accelerator pedal, works through the signal amplifier installed on the accelerator pedal, and the throttle works through the transmission of signals. When the driver steps on the accelerator pedal of the electronic accelerator, it actually sends an accelerator pedal position sensor signal to the engine ECU. The throttle is a control device for controlling the engine power. The driver controls the car's intake volume by controlling the opening of the car's throttle, thereby controlling the engine's output power.

[0011] Voltage type: Voltage type control uses the output voltage of the power supply as the feedback signal to realize the electronic throttle acceleration signal and electric proportional control, which is stepless and continuous control. It can realize the engine throttle acceleration of crane operation and the slow braking of the crane turntable rotation.

[0012] Switch type: The high and low level signals are used to output the on and off of the pedal signal, which is a two-speed control. It can realize the rapid braking of the crane turntable and the switching of the lifting operation function.

[0013] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a modular electronic pedal, including: a pedal surface, a pedal arm, a pedal seat, and a sensor. The pedal arm is hinged on the pedal seat, and the sensor is installed at the hinge position of the pedal arm and the pedal seat. The pedal surface is installed on the pedal arm, and the sensor is connected to the vehicle-mounted EDU through a wiring harness.

[0014] Furthermore, the sensor is a voltage type or switch type angle sensor.

[0015] Furthermore, it is installed in the cab and the operating room of the crane and is used for the accelerator pedal and the pedal switch.

[0016] The beneficial effects of the utility model are: adopting the modular structure of the electronic pedal, through the change of configuration, it can meet the configuration requirements of the lifting operation, and can realize the requirements of the throttle electronic acceleration function, crane slewing switch type brake, crane slewing electric proportional brake, auxiliary reel enable and other configurations; through the modular design of the electronic pedal, the style of the electronic pedal is unified, the structure is optimized, the duplication and unnecessary mold cost investment is reduced, and the research and development cycle is shortened.

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail through the following drawings and embodiments. However, it should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the scope of the utility model.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by technicians in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] like Figure 5 , 8 As shown, a modular electronic pedal includes: a pedal surface 11, a pedal arm 12, a pedal seat 13, and a sensor 14. The pedal arm 12 is hinged on the pedal seat 13, and the sensor 14 is installed at the hinge position of the pedal arm 12 and the pedal seat 13. The pedal surface 11 is installed on the pedal arm 12, or the pedal surface 11 and the pedal arm 12 are integrally formed, and the sensor 14 is connected to the vehicle-mounted EDU through a wiring harness.

[0029] The sensor 14 is an angle sensor 14 .

[0030] like Figure 6-7 As shown, the sensor 14 is a voltage type or switch type angle sensor 14. By replacing sensors 14 of different types, different signal outputs can be achieved within the full stroke angle of the pedal. Different signal output requirements can be achieved by simply replacing sensors 14 of different output types.

[0031] like Figure 2-4 As shown, it is installed in the cab and control room of the crane to replace the accelerator pedal 1 and the pedal switch 2. By selecting the electronic pedals with the same structure, the appearance, size and other characteristics of the crane pedals are guaranteed to be unified, so as to solve the problem of newly developed electronic pedals with different functions, large repeated mold investment, resulting in high development costs and waste of resources.

[0032] The accelerator pedal 1 is a voltage proportional modular electronic pedal, and the pedal switch 2 is an electric proportional type, and can also be a switch type electronic pedal, with the same appearance and different output signals.

[0033] like Figure 2 As shown, the modular electronic pedal is arranged in two rooms of the crane: the cab and the operating room, so as to realize the unification of the electronic pedals in the two rooms.

[0034] like Figure 3-4 As shown, the accelerator pedal 1 is located on the right side of the control room and the cab; the pedal switch 2 is located on the left side of the control room and may not be configured.

[0035] like Figure 6As shown, the sensor 14 in the accelerator pedal 1 is a voltage proportional sensor 14, which outputs signal 1 and signal 2. The voltage in the sensor 14 changes proportionally according to the travel angle of the pedal and is output to the EDU through the terminal pin of the sensor 14, thereby realizing electronic throttle acceleration, and then realizing the acceleration demand of lifting and hoisting;

[0036] Pedal switch 2: When the sensor 14 in the modular electronic pedal is a voltage proportional sensor 14, the voltage proportional electronic pedal realizes the electric proportional braking of the crane rotation through the signal output of the electric proportional function, thereby avoiding the problem of inertial impact caused by the emergency stop of the crane turntable rotation.

[0037] like Figure 7 As shown, pedal switch 2: When the sensor 14 in the modular electronic pedal is a voltage switch type sensor 14, during the pedal closing process, the two strokes before and after the half-stroke angle form low-level and high-level signals output to the sensor 14 to realize the rotation stop and operation of the crane turntable, or to enable the auxiliary reel.

[0038] The modular electronic pedal can be used to unify the electronic pedals in the crane's upper and lower operating rooms, and the electronic accelerator pedals of different engines can also be used to unify their structures. The voltage proportional and switch sensors only have different signal mode outputs, and their shapes and installation methods are the same, so they can be replaced as needed.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
