Patent Application
20160070293
The subject matter herein generally relates to an accelerator and brake pedal device and a vehicle using the accelerator and brake pedal device.
An accelerator and a brake pedal are separately positioned in a vehicle. Driver's right foot should operate the accelerator and the brake pedal separately. However, traffic accidents are easily caused because the driver takes an instinctive step on the accelerator pedal in an emergency.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other feature that the term modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to;” it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
The present disclosure is described in relation to an accelerator and brake pedal device and a vehicle using the accelerator and brake pedal device. The accelerator and brake pedal device can include a connecting lever, a brake pedal assembly, an accelerator pedal assembly, an accelerator control circuit, and a resisting member. The brake pedal assembly can be coupled to the connecting lever. The accelerator pedal assembly can be rotatably coupled to the brake pedal assembly. The accelerator control circuit can have an accelerator control switch. The resisting member can be positioned on the connecting lever away from the brake pedal assembly. The accelerator control switch can be resisted to turn off by the resisting member and break the accelerator control circuit. The resisting member can be moved by the accelerator pedal assembly toward the accelerator control switch. The accelerator control circuit can be rendered inoperative when the resisting member is moved by the accelerator pedal assembly toward the accelerator control switch. The accelerator control circuit can be rendered operative when the accelerator pedal assembly is released.

The brake pedal assembly 30 and the accelerator pedal assembly 50 can be positioned on the second end portion 14. The brake pedal assembly 30 and the accelerator pedal assembly 50 can cooperatively form one pedal 101. The brake pedal assembly 30 can be a lower portion of the pedal 101, and the accelerator pedal assembly 50 can be an upper portion of the pedal 101, so that a driver can just step on the one pedal 101 for braking or accelerating the vehicle 200.
The brake pedal assembly 30 can include a brake pad 32 and a first bracket 34. The first bracket 34 can include a connecting portion 342 and a supporting portion 344. The connecting portion 342 can be fixedly coupled to the second end portion 14. The supporting portion 344 can extend from the first bracket 34 and positioned away from the second end portion 14. The supporting portion 344 can be fixed to the brake pad 32 for holding and supporting the brake pad 32.
The resetting member 40 can be coupled to the rod portion 16 adjacent to the first end portion 12 for helping the connecting lever 10 returning an original position. The resetting member 40 can be a nitrogen gas spring. The resetting member 40 can include a pressure pipe 42 and a piston rod 44 movably positioned in one distal end of the pressure pipe 42. Another distal end of the pressure pipe 42 away from the piston rod 44 can be configured to couple with a portion of the vehicle frame 220. The piston rod 44 can be coupled to the rod portion 16 of the connecting lever 10. Nitrogen gas can be compressed when the brake pad 32 is forced to move downward and the piston rod 44 is moved toward the pressure pipe 42 by the connecting lever 10. The connecting lever 10 can return its original position because of a restoring force of the nitrogen gas in the pressure pipe 42 when releasing the brake pad 32.
The accelerator pedal assembly 50 can include an accelerator pad 52 and a second bracket 54 holding and supporting the accelerator pad 52. The second bracket 54 can include two mounting portions 542 and a holding portion 544 fixedly coupled to the mounting portions 542. The holding portion 544 can be positioned away from the supporting portion 344. Each mounting portion 542 can rotatably sleeve on a respective one end of the connecting portion 342. The holding portion 544 can hold and support the accelerator pad 52.
Each elastic member 60 can be sleeved on the connecting portion 342. One end of each elastic member 60 can resist a respective one mounting portion 542, and another end of the elastic member 60 can resist the supporting portion 344. In the illustrated embodiment, the elastic members 60 can be torsion springs. In other embodiments, the number of the elastic member 60 can be one, three or more.
Zigzag structures can be formed on surfaces of the brake pad 32 and the accelerator pad 52 to prevent a driver's shoe from slipping. In other embodiments, a rubber sheet can be formed on the surfaces of the brake pad 32 and the accelerator pad 52.
The accelerator control circuit 80 electrically coupled to the accelerator system. Referring to

The resisting member 90 can be coupled to the rod portion 16 and positioned adjacent to the resetting member 40. An inclined surface 92 can be formed on an end surface of the resisting member 90 away from the rod portion 16. The inclined surface 92 can contact with the roller 862.
The accelerator control circuit 80 can change from an operative state to an inoperative state via moving the operating member 86 from the operative position to the inoperative position. The accelerator control switch 82 turns on when the operating member 86 is positioned at an operative position, so that the accelerator control circuit 80 is operative. The accelerator control switch 82 turns off when the operating member 86 is positioned at an inoperative position, so that the accelerator control circuit 80 is inoperative. In the illustrated embodiment, the operative position of the operating member 86 can be where the operating member 86 is positioned adjacent to the rod portion 16; and the inoperative position of the operating member 86 can be where the operating member 86 is positioned away from the rod portion 16.
The resisting member 90 can be moved toward the operating member 86 by the connecting lever 10, the operating member 86 is moved to the inoperative position by the resisting member 90 to break the accelerator control switch 82, and then the accelerator control circuit 80 can be inoperative. The operating member 86 can automatically return the operative position when releasing the brake pad 32, so that the accelerator control circuit 80 can be operative.
In assembly, the brake pedal assembly 30 can be positioned on the second end portion 14 of the connecting lever 10. The accelerator pedal assembly 50 can be rotatably coupled to the brake pedal assembly 30. The resetting member 40 can be positioned between the connecting lever 10 and the vehicle frame 220. The accelerator shaft sensor 81 can be coupled between the holding portion 544 and the rod portion 16. The accelerator switch 82 can be positioned on the resetting member 40 and electrically coupled to the accelerator system. The resisting member 90 can be positioned on the connecting lever 10 and contact the inclined surface 92. The connecting lever 10 can be coupled to the braking system, and the accelerator control circuit 80 can be electrically coupled to the accelerator system.
A foot of the driver usually put on the pedal 101. A front portion of the foot can apply a force on the accelerator pad 52, and then the accelerator pad 52 can rotate about the connecting portion 342. The accelerator shaft sensor 81 can detect the downward movement amount of the accelerator pad 52 and sending the data to the accelerator system for accelerating. The brake pad 32 can move the connecting lever 10 to bring the driving system work, when a rear portion of the foot can apply a force on the brake pad 32. The resisting member 90 can be moved by the connecting lever 10 toward the accelerator switch 82, the operating member 86 can be moved to the inoperative position, and then the accelerator control circuit 80 can be inoperative. The operating member 86 can return the operative position and the accelerator control circuit 80 can be operative when releasing the brake pad 32. In other words, the accelerator control circuit 80 can be rendered inoperative when the resisting member 90 is moved by the accelerator pedal assembly 50 toward the accelerator control switch 82. The accelerator control circuit 80 can be rendered operative when the accelerator pedal assembly 50 is released.
The accelerator switch 82 is positioned in the accelerator control circuit 80. The accelerator switch 82 can be controlled to enable the accelerator control circuit 80 be operative or inoperative by the movement of the connecting lever 10. In emergency, traffic accidents can be avoided, when the driver step on the brake pad 32.
In other embodiments, the resetting member 40 can be not limited to be the nitrogen gas spring, and the resetting member 40 can be a torsion spring. The first bracket 34 can be integrally formed.
In other embodiments, the supporting rod 83 can be omitted, and the accelerator switch 82 can be positioned on other structures of the vehicle frame 200. A gap can exist between the resisting member 90 and the operating member 86.
