Description
Technical Field
[0001] This utility model relates to a dustproof suspended electronic throttle pedal and a commercial vehicle, belonging to the field of commercial vehicle pedal technology. Background Technology
[0002] Currently, car accelerator pedals are mainly divided into two types: mechanical cable-operated and electronic. The disadvantages of mechanical cable-operated accelerator pedals are low control precision and non-linear acceleration, resulting in poor fuel economy and an inability to meet the demands of new energy vehicles. While electronic accelerator pedals can achieve precise acceleration control and linear output, improving driving comfort, dust and sand can easily penetrate and accumulate inside the pedal in harsh conditions such as mines and sandy areas. Over time, this can lead to increased resistance in the pedal arm, causing problems such as a stuck acceleration feel and poor pedal reset. Summary of the Invention
[0003] To address the problems existing in the prior art, this utility model provides a dustproof suspended electronic throttle pedal, which reduces the amount of dust entering the pedal, ensures linear and stable pedal resistance and accurate electrical signal output, reduces the failure rate and extends service life; it is suitable for harsh working conditions such as mines and sandy areas.
[0004] This utility model also provides a commercial vehicle with a suspended electronic throttle pedal equipped with the dustproof feature.
[0005] To achieve the above objectives, this utility model employs a dustproof, suspended electronic throttle pedal, comprising:
[0006] A pedal arm assembly includes a pedal arm, one end of which is a pedal and the other end is fitted with a spring seat, on which a spring assembly is mounted.
[0007] The housing assembly includes an outer shell and a cover connected to the outer shell. The pedal arm is rotatably mounted between the outer shell and the cover. The inner wall of the outer shell is provided with an integrally formed spring retainer and a circular slide. A spring assembly is connected to the spring retainer. When the pedal arm rotates, it drives the spring assembly to move within the circular slide. An extension structure is provided in the middle of the inner wall of the outer shell. One side of the extension structure is an extension surface. When the pedal arm is stationary, the extension surface is parallel to the middle side of the pedal arm. A rubber block is installed on the other side of the extension structure. One side of the rubber block is provided with a wedge-shaped end, which is in contact with the outer wall of the pivot seat on the pedal arm.
[0008] The sensor is detachably mounted on the cover, and a decorative cover plate is installed on the sensor.
[0009] As an improvement, a raised ridge is provided on one side of the spring seat, and a corresponding groove is provided on the pedal arm. The raised ridge of the spring seat is embedded in the groove of the pedal arm to form a sliding pair.
[0010] As an improvement, a slider is provided above the pedal arm and the spring seat. The slider is snapped onto the pedal arm. The slider has a certain curvature and matches the inner wall of the housing. The edges of the slider are chamfered.
[0011] As an improvement, one side of the housing is provided with multiple mounting hole bosses, and each mounting hole boss is embedded with a metal ring.
[0012] As an improvement, the spring assembly includes a large spring, a small spring, and a sponge strip;
[0013] The spring seat connects the large spring and the small spring respectively. The large and small springs are arranged concentrically, with the large spring fitted on the outside of the small spring and the two separated by a sponge strip.
[0014] As an improvement, the inner wall of the housing is provided with a pivot, the pedal arm is mounted on the pivot via a pivot seat and rotates along the pivot, and the other end of the pivot is installed inside the cover.
[0015] As an improvement, the inner wall of the housing is provided with a limiting structure for limiting the travel of the pedal arm, and the bottom surface of the limiting structure has a certain curvature.
[0016] As an improvement, an embedded slider is installed on the pedal arm, the top surface of the embedded slider mates with the bottom surface of the limiting structure, and the end of the embedded slider is chamfered.
[0017] As an improvement, the embedded slider is made of POM and is fixed to the pedal arm by a tenon-and-mortise structure.
[0018] A second aspect of this utility model also provides a commercial vehicle equipped with the aforementioned dustproof suspended electronic throttle pedal.
[0019] Compared with existing technologies, the dustproof suspended electronic throttle pedal of this invention achieves high sealing performance and reliability through multiple structures. In terms of dustproof design, by precisely reducing the gaps in the pedal arm's movement, dust entry into the space is significantly reduced, while maintaining compatibility with other components; at the same time, elastic rubber blocks are added to fill the gaps, forming a double physical barrier.
[0020] This pedal breaks away from traditional pedaling methods, achieving linear foot feedback through dynamic resistance adjustment, resulting in a smooth and comfortable pedaling experience. Its highly sealed design allows for stable operation in harsh conditions such as sand dunes and mines, and key components utilize anti-aging engineering materials, extending its service life compared to traditional products.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this application will be described in detail below through specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.
[0031] like Figures 1 to 5 As shown, a dustproof suspended electronic throttle pedal includes a pedal arm assembly 1, a housing assembly 2, and a sensor 3.
[0032] The pedal arm assembly 1 includes a pedal arm, one end of which is a pedal 11, and the other end is fitted with a spring seat 12, on which a spring assembly 13 is mounted.
[0033] The housing assembly 2 includes an outer shell 21 and a cover 24 connected to the outer shell 21. For example, a second screw 5 connects the outer shell 21 and the cover 24. The pedal arm is rotatably mounted between the outer shell 21 and the cover 24. An integrally formed spring retainer 22 and a circular slide 23 are provided on the inner wall of the outer shell 21. One end of the spring assembly 13 is connected to the spring seat 12, and the other end is connected to the spring retainer 22. When the pedal arm rotates, it drives the spring assembly 13 to move within the circular slide 23. The circular slide 23 ensures that the spring assembly 13 moves within a limited range, reducing friction generated during spring movement and preventing uneven wear and jamming caused by spring movement. The middle part of the inner wall of the outer shell 21... An extension structure is provided, one side of which is an extension surface 27. When the pedal arm is stationary, the extension surface 27 is parallel to the middle side surface 17 of the pedal arm. By setting the extension surface 27 parallel to the middle side surface 17 of the pedal arm, the gap of the pedal arm is greatly reduced, preventing the entry of foreign objects, which is the first measure to prevent dust from entering. The other side of the extension structure is connected to a rubber block 28. One side of the rubber block 28 is provided with a wedge-shaped end 28a. The wedge-shaped end 28a is in contact with the outer wall of the pivot seat 16 in the middle of the pedal arm. When the pedal arm rotates, the wedge-shaped end 28a of the rubber block 28 cleans the dust adsorbed on the outer wall of the pivot seat 16, which is the second measure to prevent dust from entering.
[0034] The sensor 3 is mounted on the cover 24 by the first screw 4, which also fixes the decorative cover plate 6 to the sensor 3, making it easy to install and remove.
[0035] As an improvement to the embodiment, such as Figure 2 As shown, a raised ridge is provided on one side of the spring seat 12, and a corresponding groove is provided on the pedal arm. The raised ridge of the spring seat 12 is embedded in the groove of the pedal arm to form a sliding pair. The ridge extends along the length of the pedal arm, restricting the radial movement of the spring seat 12 on the pedal arm and allowing it to slide only along the ridge direction (axial direction). The spring seat 12 moves at its upper limit on the pedal arm through the ridge, which allows the pedal arm to reduce the bending angle of the spring when it makes an arc-shaped movement around the pivot 210, thereby ensuring the linearity of the foot resistance of the pedal 11.
[0036] As an improvement to the embodiment, such as Figure 2 , Figure 3As shown, a slider 14 is provided above the pedal arm and spring seat 12. The slider 14 is engaged with the pedal arm. The slider 14 has a certain curvature and matches the inner wall of the outer shell 21. All edges of the slider 14 are chamfered. The slider 14 can be made of POM (polyoxymethylene). The slider 14 can limit the spring seat 12. At the same time, due to the lubricating properties of POM material, the frictional resistance is greatly reduced, making the resistance more linear and the foot feel smoother and more comfortable. In addition, the slider 14 has a certain curvature and is chamfered, which allows the pedal arm to fit against the inner wall of the outer shell 21 when it moves in an arc around the pivot 210, forming a stable motion guide. The chamfer design can prevent the front and rear edges of the slider 14 from scraping against the inner wall of the outer shell 21 during the movement of the spring assembly 13, which would cause the electronic throttle pedal to stick.
[0037] As an improvement to the embodiment, such as Figure 2 , Figure 4 and Figure 5 As shown, one side of the outer casing 21 is provided with multiple mounting hole bosses 25, and each mounting hole boss 25 is embedded with a metal ring 26 for structural reinforcement. For example, providing three mounting hole bosses 25 not only facilitates installation but also ensures a stable connection. Furthermore, the use of metal rings 26 for structural reinforcement not only prevents cracking of the mounting holes due to insufficient plastic strength during installation but also ensures a stable connection with the screws over a long period, preventing the accelerator pedal from loosening when driving on bumpy roads.
[0038] As an improvement to the embodiment, such as Figure 2 As shown, the spring assembly 13 includes a large spring 131, a small spring 132, and a sponge strip 133;
[0039] The spring seat 12 connects a large spring 131 and a small spring 132, which are concentrically arranged. The large spring 131 is fitted over the outer side of the small spring 132, and the two are separated by a sponge strip 133. One end of each spring is fixed to a spring clip 22 inside the outer shell 21, and the other end is fixed to the spring seat 12. This concentric double-spring design ensures that even if one spring fails, the pedal can still return to its initial position. The sponge strip 133 prevents the two springs from colliding and causing noise or jamming. When the pedal is pressed, the spring is compressed and generates resistance. The deeper the pedal is pressed, the greater the spring resistance, resulting in a more linear resistance and a smoother, more comfortable feel compared to a cable-operated pedal.
[0040] As an improvement to the embodiment, such as Figure 2 , Figure 4 and Figure 5As shown, the inner wall of the housing 21 is provided with a rotating shaft 210. The pedal arm is mounted on the rotating shaft 210 via a rotating shaft seat 16 and rotates along the rotating shaft 210. The other end of the rotating shaft 210 is installed inside the cover 24. Since the rotating shaft 210 is located between the housing 21 and the cover 24, the sensor 3 and the rotating shaft 210 of the pedal arm do not contact each other. This contactless design allows the sensor 3 to output a high-precision voltage signal, making it more durable and stable than mechanical structures.
[0041] As an improvement to the embodiment, such as Figure 2 , Figure 4 and Figure 5 As shown, the inner wall of the outer casing 21 is provided with a limiting structure 29 for limiting the travel of the pedal arm. The bottom surface of the limiting structure 29 has a certain curvature. The limiting structure 29 allows for precise control of the pedal 11's travel, preventing excessive force from the driver, which could lead to excessive pedal arm travel and signal failure. Furthermore, the design of the pedal arm's bending angle and the pedal angle conforms to ergonomics, effectively reducing driver fatigue. Additionally, the curved bottom surface of the limiting structure 29 reduces the entry range of dust and foreign objects, serving as a third layer of dust prevention.
[0042] As an improvement to the embodiment, such as Figure 2 , Figure 3 As shown, an embedded slider 15 is installed on the pedal arm. The embedded slider 15 is made of POM and is fixed to the pedal arm by a tenon structure. The top surface of the embedded slider 15 is an arc-shaped curved surface, which matches the arc of the bottom surface of the limiting structure 29 to ensure that the two are always in contact during the movement of the pedal arm. The end of the embedded slider 15 has a chamfer. After the chamfering treatment, a smooth transition surface is formed, which effectively blocks the movement gap between the pedal arm and the outer shell 21, further reducing the space for dust and foreign objects to enter. It is the fourth measure to prevent dust from entering.
[0043] A second aspect of this utility model also provides a commercial vehicle equipped with the aforementioned dustproof suspended electronic throttle pedal.
[0044] This utility model discloses a dustproof suspended electronic throttle pedal that achieves high sealing and reliability through multiple structural elements. In terms of dustproof design, the gaps in the pedal arm's movement are precisely minimized, significantly reducing dust ingress while maintaining compatibility with other components. Additionally, elastic rubber blocks are added to fill the gaps, forming a double physical barrier. Furthermore, the pedal arm and housing are designed to fit snugly, effectively preventing dust intrusion through curved surface tolerances.
[0045] In terms of structural reliability, a reinforced three-point mounting hole layout is adopted. Through thickened hole structure and anti-loosening thread design, the risk of stripping of mounting screws is greatly reduced, while reducing damage to mounting holes and significantly improving assembly efficiency and stability. In terms of sensing technology, a non-contact Hall sensor is used to replace the traditional mechanical potentiometer, eliminating the risk of wear and improving the accuracy of throttle signal, achieving high linearity and real-time performance of electrical signal output.
[0046] In terms of ergonomic optimization, this pedal breaks through the traditional pedaling mode, achieving linear foot feedback through dynamic resistance adjustment, resulting in a smooth and comfortable pedaling experience. Its high-sealing design allows it to operate stably in harsh conditions such as sand dunes and mines, and key components utilize anti-aging engineering materials, extending its service life compared to traditional products. Furthermore, the pedal angle and contact surface are ergonomically designed to fit the human foot, reducing driver fatigue through testing and balancing operational precision with driving comfort.
[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
