Description

Technical Field

[0001] This utility model relates to a compact suspended electronic accelerator pedal structure. Background Technology

[0002] The electronic accelerator pedal is an important component of ETC (Electronic Throttle Control). The electronic accelerator pedal works by using a position sensor to transmit signals regarding the depth and speed of pedal depressing to the engine control unit (ECU). The ECU then issues commands to control the throttle opening, thereby allowing the engine to provide matching power. With the booming development of the passenger vehicle market and the increasing electrification of vehicles, the application of electronic accelerator pedals in passenger vehicles is becoming more widespread. This has also placed higher demands on the installation space and cost of electronic accelerator pedals in the driver's cabin. Currently, electronic accelerator pedals are relatively large and have high production costs, failing to meet the current needs of the passenger vehicle market. Utility Model Content

[0022] Example

[0023] Reference Figures 1-6 This embodiment provides a compact suspended electronic accelerator pedal structure, including a base 1, a connecting rod 2, a friction structure, a pedal 5, a spring seat 6, a spring 4, and an electronic housing 9. The connecting rod 2 is rotatably mounted on the base 1. The friction structure is located at the connection end between the connecting rod 2 and the base 1. The pedal 5 is located at the end of the connecting rod 2 away from the base 1. The spring seat 6 is located at the bottom inside the base 1. The spring 4 is located between the spring seat 6 and the connecting rod 2. The electronic housing 9 is located on the outside of the base 1 away from the connecting rod 2, and the electronic housing 9 and the base 1 are an integral structure.

[0024] The base 1 serves as the mounting foundation for the entire electronic accelerator pedal 5 and is fixedly installed on the vehicle body. An electronic housing 9 is provided on the top of the base 1, and the electronic housing 9 and the base 1 are an integral structure to reduce the number of molds and lower the cost of the electronic accelerator pedal 5. A connecting rod 2 is rotatably mounted on the base 1, and a friction structure is provided at the connection end between the connecting rod 2 and the base 1. By placing the friction structure at the rotating end of the connecting rod 2, the overall structure of the electronic accelerator pedal 5 is made more compact, which helps to reduce the installation space of the electronic accelerator pedal 5. A pedal 5 is installed at the end of the connecting rod 2 away from the base 1 so that the connecting rod 2 can be rotated relative to the base 1 when the pedal 5 is pressed. A spring seat 6 is installed at the bottom inside the base 1. One end of the spring 4 is fixedly mounted on the spring seat 6, and the other end of the spring 4 is fixedly mounted on the bottom of the connecting rod 2. In the initial state, the connecting rod 2 can be in an upward movement state. In this embodiment, by concentrating the positions of the friction structure and the spring compression structure of the connecting rod 2 at the rotating end of the connecting rod 2, the overall structure of the electronic accelerator pedal 5 is made more compact, thereby reducing the installation space of the electronic accelerator pedal 5.

[0025] Specifically, the friction structure includes a cylindrical boss 7, a bearing ring 3, and a friction surface 10. The cylindrical boss 7 is symmetrically fixed on the left and right sides of the connection end between the connecting rod 2 and the base 1. The bearing ring 3 is fixed on the cylindrical boss 7. The friction surface 10 is symmetrically arranged on the upper sides of the inner cavity of the base 1. The friction surface 10 cooperates with the bearing ring 3.

[0026] The friction structure in this embodiment mainly consists of cylindrical bosses 7, bearing rings 3, and friction surfaces 10. Two cylindrical bosses 7 are symmetrically installed on the left and right sides of the connection end between the connecting rod 2 and the base 1. Bearing rings 3 are fixedly installed on the cylindrical bosses 7. Friction surfaces 10 are symmetrically arranged on the upper sides of the inner cavity of the base 1, and the friction surfaces 10 and the bearing rings 3 cooperate with each other to make the structure of the entire suspension electronic accelerator pedal 5 more compact.

[0027] Furthermore, the friction surface 10 has a quarter-circle arc structure.

[0028] In this embodiment, the friction surface 10 is designed as a quarter-circle arc structure to reduce the installation space of the suspended electronic accelerator pedal 5.

[0029] Furthermore, the bottom of the inner cavity of the base 1 is symmetrically provided with arc-shaped grooves 13 that cooperate with the spring seats 6.

[0030] In this embodiment, the base 1 has symmetrically arranged arc grooves 13 on both sides of the bottom of the inner cavity to cooperate with the spring seat 6. During installation, the spring seat 6 can be snapped into the arc groove 13 so that the spring seat 6 can be flipped with the arc groove 13 as the fulcrum.

[0031] Furthermore, the connection end between the connecting rod 2 and the base 1 is also provided with a magnetic block coated with rubber 8.

[0032] In this embodiment, by placing the magnetic block coating 8 at the connection end between the connecting rod 2 and the base 1 to install the magnetic block, the number of parts of the suspended electronic accelerator pedal 5 is reduced, which not only reduces the cost of the suspended electronic accelerator pedal 5, but also further reduces the installation space of the suspended electronic accelerator pedal 5.

[0033] Initially, connecting rod 2 is subjected to the elastic force of spring 4, causing it to move upwards. The front part of connecting rod 2 contacts the upper part of base 1, forming an initial position limiting surface to limit movement. Spring seat 6, subjected to the elastic force of spring 4, utilizes the lever principle to cause it to rotate around the arc groove 13 on base 1 as a fulcrum, pressing against bearing ring 3. Simultaneously, bearing ring 3, under pressure, presses against the friction surface 10 at the front end of base 1. Under full load, connecting rod 2 drives the bearing rings 3 fixedly mounted on both sides and the bearing rings on one side... The magnetic block overcomes the elastic force of the spring 4 and the contact surface of the bearing ring 3 squeezed by the spring seat 6, as well as the lag force generated by the bearing ring 3 being squeezed by the elastic force of the spring 4 on the friction surface 10 at the front end of the base 1, and rotates relative to each other, so that the connecting rod 2 is in a downward movement state. At this time, the lower part of the connecting rod 2 contacts the rear end of the base 1, forming a full-load limiting surface 12. It should be noted that during installation, the connecting rod 2, bearing ring 3, magnetic block, spring 4 and spring seat 6 are installed together from the tail opening of the base 1, so that there is enough space at the lower end of the base 1 for the installation of a positioning structure.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
