Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to a novel integrated pedal assembly. Background Technology

[0002] The pedal assembly refers to the complete set of components in motor vehicles such as automobiles, motorcycles, and construction machinery, used by the driver to control the vehicle's acceleration, braking, and clutch operation. It is usually composed of multiple sub-components, including pedals, linkages, springs, sensors, brackets, etc. The pedal assembly is an important interface between the driver and the vehicle control system, directly affecting driving safety and comfort. The pedal assembly is a crucial component of motor vehicles, responsible for the driver's control of the vehicle's acceleration, braking, and clutch.

[0003] In the technological evolution of automotive pedal assemblies, traditional brake pedal arms are generally constructed of metal. Their significant weight not only increases the overall vehicle load but also, to some extent, interferes with the vehicle's handling sensitivity and precision. Furthermore, the complex composition of metal brake pedal arms directly leads to the need for more manual labor in the assembly process, thereby increasing labor costs. Moreover, the corrosive nature of metal materials poses a risk of performance degradation and even structural damage due to corrosion, severely restricting the durability and reliability of the pedal assembly and creating hidden dangers for the stable operation of the automotive braking system. To address these issues, we propose a novel integrated pedal assembly. Utility Model Content

[0004] The purpose of this invention is to provide a novel integrated pedal assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel integrated pedal assembly includes a brake bracket. A slot is formed on the upper surface of the brake bracket, through which a brake pedal arm is engaged. A transition column is fixedly connected to the upper surface of the brake pedal arm. A transition block is fixedly connected to the left side of the transition column, and a linkage shaft is fixedly connected to the left side of the transition block. An accelerator pedal assembly is located above the brake bracket. A transition plate is fixedly connected to the bottom surface of the accelerator pedal assembly. A first mounting pin and a second mounting pin are threaded onto the upper surface of the transition plate. The accelerator pedal assembly is connected via the first mounting pin, the second mounting pin, and the transition plate. The plate is fixedly connected to the brake bracket. A first coaxial sensor and a second coaxial sensor are respectively provided on the upper part of the brake bracket. The inner walls of the first coaxial sensor and the inner walls of the second coaxial sensor are both fitted with mounting bushings. The inner wall of each mounting bushing is threaded with a positioning pin. The first coaxial sensor, the second coaxial sensor and the brake pedal arm are all fitted with the linkage shaft and the brake bracket through the positioning pins. A bracket is fixedly connected to the outer surface of the first coaxial sensor. A pedal force simulator is fixedly embedded on the upper surface of the brake bracket. A power data interface is fixedly connected to the upper surface of the first coaxial sensor.

[0007] In a further embodiment, the upper surface of the brake bracket is provided with a set of positioning grooves, and the upper surface of each positioning groove is provided with a mounting hole.

[0008] In a further embodiment, an accelerator pedal pad is fixedly connected to the end of the accelerator pedal assembly away from the brake bracket, and an anti-slip protrusion for the accelerator pedal pad is fixedly connected to the upper surface of the accelerator pedal pad.

[0009] In a further embodiment, a brake pad is fixedly connected to the end of the brake pedal arm away from the brake bracket, and the upper surface of the brake pad is provided with anti-slip texture.

[0010] In a further embodiment, the brake bracket is made of plastic-coated iron core.

[0011] In a further embodiment, the outer surface of the accelerator pedal assembly is coated with a corrosion-resistant layer, a protective plate is provided on the right side of the brake pedal arm, and a locking pin is fixedly connected to the left side of the protective plate. The protective plate is fixedly connected to the brake pedal arm through the locking pin.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device accurately captures the displacement and angle of the brake pedal arm through a first and a second coaxial sensor, converting this information into electrical signals that are transmitted to the vehicle control system. This enables precise adjustment of the braking system. By integrating the brake pedal arm, accelerator pedal assembly, coaxial sensors, and pedal force simulator into a single brake bracket structure, it achieves a high degree of integration. This not only optimizes the overall layout of the pedal assembly but also reduces the number of parts. The brake pedal arm, made of plastic-coated iron core through injection molding, exhibits excellent corrosion resistance, ensuring good performance even in harsh environments and extending its service life. Furthermore, the fork-type structure of the brake switch effectively eliminates the impact of brake pedal arm return impact on the switch. Compared to conventional mechanical and Hall effect brake switches, this significantly reduces the risk of switch failure and greatly enhances the safety and durability of the entire vehicle braking system.

A transition block 14 is fixedly connected to the left side of the transition column 13, and a linkage shaft 17 is fixedly connected to the left side of the transition block 14. An accelerator pedal assembly 4 is located above the brake bracket 1, and a transition plate 22 is fixedly connected to the bottom surface of the accelerator pedal assembly 4. The upper surface of the connecting plate 22 is threaded with a first mounting pin 24 and a second mounting pin 25, respectively. The accelerator pedal assembly 4 is fixedly connected to the brake bracket 1 via the first mounting pin 24, the second mounting pin 25, and the adapter plate 22. A first coaxial sensor 2 and a second coaxial sensor 8 are respectively provided above the brake bracket 1. The inner walls of the first coaxial sensor 2 and the second coaxial sensor 8 are both fitted with mounting bushings 18. The inner wall of each mounting bushing 18 is threaded with a positioning pin 11.

A power data interface 26 is fixedly connected to the upper surface of the first coaxial sensor 2. The brake pedal arm 3 will rotate around its connection point with the brake bracket 1. The motion information of the brake pedal arm 3 will be sensed by the first coaxial sensor 2. The first coaxial sensor 2 converts the displacement, angle and other motion parameters of the brake pedal arm 3 into electrical signals through internal sensing elements. Similarly, when other actions or status monitoring related to braking are involved, the second coaxial sensor 8 will also play a similar sensing role, achieving a high degree of integration. This not only optimizes the overall layout of the pedal assembly but also reduces the number of parts. The brake pedal arm 3, which is injection molded with a plastic-coated iron core, has excellent corrosion resistance, ensuring that it can maintain good performance in various harsh environments and extending the service life of the pedal arm.

[0026] A brake pedal arm 3 is fixedly connected to a brake pad 5 at the end away from the brake bracket 1. The upper surface of the brake pad 5 is provided with anti-slip texture 20, which can significantly increase the friction between the driver's foot and the brake pedal. The brake bracket 1 is made of plastic-coated iron core. The brake pedal arm 3, which is injection molded using plastic-coated iron core, has excellent corrosion resistance, which ensures that it can still maintain good performance in various harsh environments and extends the service life of the pedal arm. The outer surface of the accelerator pedal assembly 4 is coated with a corrosion-resistant layer 23. A guard plate 15 is provided on the right side of the brake pedal arm 3. A locking pin 16 is fixedly connected to the left side of the guard plate 15. The guard plate 15 is fixedly connected to the brake pedal arm 3 through the locking pin 16.

[0027] The working principle of this utility model is as follows:

[0028] When the driver presses the brake pedal arm 3, the brake pedal arm 3 rotates around its connection point with the brake bracket 1. The motion information of the brake pedal arm 3 is sensed by the first coaxial sensor 2. The first coaxial sensor 2 converts the displacement, angle and other motion parameters of the brake pedal arm 3 into electrical signals through its internal sensing element. Similarly, when other actions or status monitoring related to braking are involved, the second coaxial sensor 8 will also play a similar sensing role. When the driver presses the brake pedal arm 3 or the accelerator pedal assembly 4, the pedal force simulator 10 will generate corresponding resistance or assistance according to the vehicle's operating state. It can provide the driver with a pedal operation feel similar to that of a traditional vehicle without traditional mechanical connection, thereby improving driving comfort and safety.
