Description

Technical Field

[0001] The utility model relates to the technical field of automobile electronic accessories, in particular to an electronic accelerator pedal sensor assembly. Background Art

[0002] With the rapid development of the automobile industry and the continuous improvement of the degree of electrification, the Electronic Throttle Control System (ETCS) has gradually replaced the traditional cable-type mechanical throttle system and become the standard configuration of modern vehicles due to its excellent control accuracy, response speed and fault diagnosis ability. As a key component of ETCS, the reliability of the function and the stability of operation of the electronic throttle pedal sensor assembly directly affect the power output control effect of the vehicle and the driver's operating experience.

[0003] Traditional electronic accelerator pedal sensor assemblies usually use a shaft connection or a connecting rod mechanism to convert the pedal displacement into an electrical signal that can be recognized by the sensor. However, such designs have the following potential problems:

[0004] 1. Insufficient motion trajectory constraints: The traditional pedal-to-shell connection structure mainly relies on the accuracy and lubrication of the sleeve, as well as the stiffness and assembly accuracy of the connecting rod system to constrain the pedal's rotational motion. During long-term use, due to wear, deformation or lubrication failure, the pedal may sway, shake or have nonlinear displacement, resulting in inaccurate pedal position information read by the sensor, which in turn affects the accuracy of throttle control.

[0005] 2. Poor stability: Under extreme conditions (such as intense driving or bad road conditions), the pedal may be subjected to a large impact force, which puts the stability of the traditional connection structure to the test. Pedals that lack effective buffering and guiding mechanisms are prone to excessive vibration or instantaneous displacement, which not only affects the driver's operating feel of the accelerator pedal, but may also cause sensor mis-triggering or signal distortion, posing a potential threat to vehicle driving safety.

[0006] In view of the above defects, the present application proposes an electronic throttle pedal sensor assembly that can guide and limit the movement of the pedal. Utility Model Content

[0008] The technical solution adopted by the utility model is: an electronic throttle pedal sensor assembly, including a shell, a pedal and a spring assembly, the pedal is rotatably connected to the shell, the side wall of the shell is convex to form an arc-shaped step, the pedal is located at a position corresponding to the arc-shaped step and convex to form two steps, a sliding groove for sliding cooperation with the arc-shaped step is formed between the two steps, and the curvature of the arc-shaped step is adapted to the rotation curvature of the sliding groove at the corresponding position of the pedal.

[0009] Furthermore, the spring assembly consists of an inner spring and an outer spring.

[0010] Furthermore, a spring seat is provided on the end of the pedal located in the shell, a first inner spring column for fitting one end of the inner spring is provided in the spring seat, and a first positioning ring for fitting one end of the outer spring is provided on the outer ring of the first inner spring column.

[0011] Furthermore, a reinforcing rib is provided at the outer bottom of the first inner spring column.

[0012] Furthermore, a second inner spring column for fitting one end of the inner spring is provided on the shell body located above the spring seat, and a second positioning ring and a third positioning ring are provided on the outer ring of the second inner spring column, and a spring groove for positioning the outer spring is formed between the second positioning ring and the third positioning ring.

[0013] Furthermore, the housing includes a bottom shell and a cover plate covering the bottom shell, the arc-shaped step is arranged on the cover plate, and the second inner spring column, the second positioning ring and the third positioning ring are arranged on the bottom shell.

[0014] Furthermore, the cover plate is provided with an elastic buckle ring, and the bottom shell is provided with a boss that is buckled with the elastic buckle ring.

[0015] Furthermore, mounting plates are extended from both ends of the bottom shell, and "U"-shaped mounting holes are provided on the mounting plates.

[0016] The utility model provides an electronic accelerator pedal sensor assembly, which realizes effective guidance and stable control of pedal rotation through a uniquely designed arc-shaped step and slide groove matching structure, bringing significant technical advantages and practical application value. The specific beneficial effects are as follows:

[0017] 1. Accurately control the movement trajectory of the pedal: This application sets an arc-shaped step that matches the pedal on the side wall of the shell, and forms two corresponding steps on the pedal to form a slide groove, ensuring that the pedal slides accurately along the preset arc-shaped trajectory during operation. This design effectively overcomes the pedal displacement deviation problem that may be caused by factors such as wear and deformation of the traditional pedal connection structure, ensures that the sensor can always accurately sense the actual position of the pedal, and improves the accuracy of throttle control.

[0018] 2. Significantly enhance pedal stability: The close cooperation between the arc-shaped step and the slide groove provides strong support and guidance, greatly reducing the shaking and swaying of the pedal during operation, especially when dealing with the instantaneous impact force under severe driving conditions, and can maintain the continuity and stability of the pedal movement. This stable pedal motion characteristic helps to reduce the fluctuation and noise of the sensor signal, ensuring that the electronic throttle control system can accurately and promptly respond to the driver's intentions, and improving driving control and driving safety.

[0019] 3. Optimize pedal feel and comfort: The combination of the curved step and the slide can ensure that the pedal moves smoothly and evenly along the predetermined track, avoiding problems such as pedal jamming and jumping that may be caused by the traditional structure, thereby giving the pedal a more delicate and consistent resistance feedback and operating feel. The driver can get a clearer pedal position perception when operating the accelerator pedal, which is conducive to achieving fine power control and improving driving comfort.

A side wall of the housing is raised to form an arc-shaped step 3. The pedal is located at a position corresponding to the arc-shaped step and is raised to form two steps 4. A slide groove 5 for sliding cooperation with the arc-shaped step is formed between the two steps. The curvature of the arc-shaped step is adapted to the rotation curvature of the slide groove at the corresponding position of the pedal.

[0032] In this embodiment, the electronic throttle pedal sensor assembly described is provided with an arc-shaped step on the side wall of the housing that matches the slide groove formed by the two steps on the pedal, so as to ensure that when the pedal is rotatably connected to the housing, its motion trajectory strictly follows the preset arc-shaped path. This design effectively constrains the rotation angle and stroke of the pedal, prevents the pedal from deflecting and shaking during operation, significantly improves the stability of the pedal action and the accuracy of sensor detection, and is conducive to achieving precise throttle control.

[0033] Specifically, the spring assembly consists of an inner spring 6 and an outer spring 7; a spring seat 8 is provided on the end of the pedal located in the shell, a first inner spring column 9 for fitting one end of the inner spring is provided in the spring seat, and a first positioning ring 10 for fitting one end of the outer spring is provided on the outer ring of the first inner spring column; a reinforcing rib 11 is provided at the outer bottom of the first inner spring column.

[0034] The spring seat arranged at the end of the pedal integrates the first inner spring column and the first positioning ring, so that the inner spring and one end of the outer spring can be accurately and firmly mounted on the pedal. A reinforcing rib is added to the bottom of the outer periphery of the first inner spring column to enhance the connection strength between the spring seat and the spring column, prevent the spring seat from deforming or breaking during frequent pedal movement, ensure the long-term stable operation of the spring assembly, and extend the service life of the pedal assembly.

[0036] The second inner spring column, the second positioning ring and the third positioning ring arranged on the housing above the spring seat provide precise positioning and fixing structures for the other ends of the inner spring and the outer spring. The spring groove between the second positioning ring and the third positioning ring ensures that the outer spring remains stable during compression and extension, preventing the spring from deflecting or falling out, further improving the stability of the pedal action. This segmented spring installation structure facilitates the disassembly and maintenance of the spring, reducing maintenance costs.

[0038] The shell is divided into a bottom shell and a cover plate. The arc-shaped step is arranged on the cover plate, and the second inner spring column, the second positioning ring and the third positioning ring are arranged on the bottom shell. This split design is conducive to simplifying the production process and facilitating assembly and maintenance. The cover plate and the bottom shell are tightly connected by the elastic buckle ring and the boss, which not only ensures the sealing inside the shell, but also facilitates quick disassembly and assembly, thereby improving assembly efficiency.

[0039] Specifically, mounting plates 20 are extended from both ends of the bottom shell, and “U”-shaped mounting holes 21 are provided on the mounting plates.

[0040] The mounting plates extending from both ends of the bottom shell are provided with "U"-shaped mounting holes, which provide a standardized and convenient mounting interface for the electronic accelerator pedal sensor assembly. This design enables the assembly to be easily adapted to the mounting brackets of different models, simplifies the installation process, reduces assembly errors, improves the versatility and reliability of the installation, and helps to shorten the assembly time of the vehicle production line and improve production efficiency.
