Problems solved by technology

This form has a simple structure and low cost, but the operation method is completely different from the original double-pedal structure, which brings great inconvenience to the user's operation, and the operation convenience and comfort are poor.
For this reason, many manufacturers and people of insight have developed and developed, but so far no ideal products have come out.

Abstract

The invention discloses a coaxial type speed change and foot brake mechanism which comprises a rack (1), a pedal brake device (41), an electronic pedal device (42), a backing pedal device (43) and a heading pedal device (44). A rear axle (16) is arranged on the rack (1), a motor (11) on the rear axle (16) drives rear wheels (12) to rotate, and the pedal brake device (41) and the heading pedal device (44) are installed on a backing pedal connecting rod (34) of the backing pedal device (43); a speed change arm (26) of the electronic pedal device (42) is installed between a connecting sheet (35)and a heading pedal seat (38) and is in linkage with an electronic pedal (10), a heading pedal (27) and a backing pedal (24) respectively drive the speed change arm (26) to rotate, and in the rotationprocess, the output voltage of the electronic pedal (10) is changed to control the rotation speed of the motor (11); and a brake pedal (3) and a rear axle brake arm (14) are in linkage. After the structure is adopted, the coaxial type speed change and foot brake mechanism has the beneficial effects of being compact in structural design, easy to operate, convenient to install and use, good in universality and comfort performance and the like.

Description

technical field [0001] The invention relates to the field of vehicle speed change control and brake technology, in particular to a coaxial speed change and foot brake mechanism for low-speed electric vehicles. Background technique [0002] At present, low-speed electric vehicles, such as lawn mowers, have more hand-operated actions when they are in use, and the lawn mowers are all running at low speeds. Therefore, traditional hydraulic continuously variable gasoline-powered lawn mowers widely use a forward pedal and a reverse pedal. Realize the forward or reverse and variable speed operation of the machine. [0003] With the continuous improvement of new energy technology and the continuous decline of production costs, electric lawn mowers have also developed rapidly as an emerging product. The speed change mechanism of the electric lawn machine has also changed the original control structure. At present, the electronic pedal is basically used to adjust the motor speed, and...
