Description

Technical Field

[0001] This application relates to the field of vehicle control technology, specifically to an accelerator pedal limiter. Background Technology

[0002] With the development of vehicle electronic control systems, accelerator pedal travel control plays a crucial role in driving safety, energy efficiency, and driver training. Especially in scenarios such as driver training, vehicle testing, or speed-limited driving, it is often necessary to install accelerator pedal limiters to restrict the maximum travel of the accelerator pedal, preventing accidental acceleration and improving driving safety.

[0003] Currently, most driving school vehicles are equipped with mechanical accelerator pedal limiters. These limiters are installed on the accelerator pedal support rod and switch between the limit and release states using a swing arm, slide, or pin structure. For example, Chinese utility model patent CN207955341U discloses an accelerator pedal limiter that achieves limit control through the swinging limit arm and the insertion and removal of a pin.

[0004] However, despite their widespread installation in the driver training industry, these devices are rarely used. This is because their limiting and releasing operations rely on manual insertion and removal of pins and alignment of sliding blocks, a cumbersome process requiring bending over and stooping, resulting in low efficiency. In daily training scenarios involving frequent starts and stops and frequent driver changes, instructors often avoid frequent use to save time, leading to a widespread situation where the limiting devices are "installed but not used." Because the limiting function is not activated in a timely manner, accidents such as students accidentally pressing the accelerator or accelerating suddenly still occur frequently. Utility Model Content

[0005] This application provides an accelerator pedal limiter to solve the technical problem that the existing accelerator pedal limit mechanism is inconvenient to operate.

[0006] According to one aspect of this application, an accelerator pedal limiter is provided, comprising: A fixed mounting assembly includes a mounting bracket having mounting holes for fitting onto an accelerator pedal support rod; The limiting support assembly includes a support plate and a support rod fixed on the support plate. The support plate and the mounting bracket rotate around a transverse rotation center axis, so that the support rod has a vertical limiting state and a transverse non-limiting state. In the limiting state, the end of the support rod is used to press against the vehicle floor to limit the travel of the accelerator pedal; in the non-limiting state, the end of the support rod is detached from the vehicle floor. A locking assembly includes a locking plate and a locking rod. The locking plate is fixedly connected to the mounting bracket. The locking plate is provided with a limiting groove. The locking rod is installed on the support plate and rotates synchronously with the support plate. The locking rod is used to engage with the limiting groove when the support plate is in a limited position. An elastic reset element is disposed between the mounting bracket and the support plate, and is used to apply an elastic force to the support plate to reset it to a non-limited state.

[0007] Optionally, the locking rod includes a base and a rod. The base is fixed to the support plate, and the rod is rotatably connected to the base. The rotation center line of the rod relative to the base is perpendicular to the rotation center line of the support plate relative to the mounting bracket. The locking plate has a guide groove communicating with the limiting groove. The guide groove is perpendicular to the limiting groove and is used to guide the locking rod into the limiting groove.

[0008] Optionally, the elastic reset element is a spring, one end of which is connected to the support plate and the other end to the locking plate; the connection point between the spring and the support plate and the connection point between the locking rod and the support plate are located on both sides of the rotation center of the support plate; when the support rod is in the non-limited state, the spring is in the initial state; when the support rod rotates to the limited state, the spring is stretched, applying a torsional force to the support plate, and simultaneously providing a force to cause the locking rod to move towards the limiting groove.

[0009] Optionally, the locking rod is offset relative to the guide groove, so that when the rod slides in the guide groove, it is squeezed by the side wall of the guide groove and rotates, tilting away from the limiting groove.

[0010] Optionally, the limiting groove is provided with an anti-detachment protrusion on the side near the guide groove, and the anti-detachment protrusion and the side wall of the limiting groove have an arc transition.

[0011] Optionally, a pedal is provided at the end of the locking lever away from the support plate, and the pedal is set at a preset angle with the locking lever.

[0012] Optionally, the end of the support rod away from the support plate is provided with an elastic support head.

[0013] Optionally, the support rod is threaded into the support plate, and the length of the support rod extending out of the support plate can be adjusted by rotating the support rod.

[0014] Optionally, the mounting bracket includes a U-shaped clamping plate and locking bolts passing through the two free ends of the clamping plate, with the mounting hole formed between the locking bolts and the clamping plate.

[0015] Optionally, the elastic reset element is a torsion spring, and the support plate is provided with a rotating shaft. The torsion spring is sleeved on the rotating shaft and is used to provide the torsional reset torque of the support plate.

[0016] In summary, this application includes at least one of the following beneficial technical effects: The accelerator pedal limiter of this invention, after being installed on the support rod of the accelerator pedal, allows for quick switching between the limit and release states directly with the foot, avoiding the cumbersome operation and manual insertion / removal of pins required in existing technologies. Specifically, the driver only needs to lightly move the locking rod with their foot, causing it to move along the guide direction and engage in the limit groove. The locking rod and support plate rotate synchronously, driving the support rod to rotate around the horizontal axis to the vertical limit state. At this point, a fixed gap is formed between the bottom end of the support rod and the vehicle floor, thereby limiting the maximum downward travel of the accelerator pedal and achieving travel limit. When it is necessary to release the limit, the driver again moves the locking rod with their foot, causing it to exit the limit groove. Under the action of the elastic reset component, the support plate, support rod, and locking rod rotate synchronously in the opposite direction and return to the horizontal non-limit state. The entire switching process does not require bending over or disassembling parts; the limit and release can be completed with a simple foot movement, improving the ease of operation of the limit mechanism.

Detailed Implementation

[0021] The embodiments of this application are described in detail below with reference to the accompanying drawings; however, this application may be implemented in a variety of different ways as defined and covered below.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] like Figure 1 As shown, this embodiment provides an accelerator pedal limiter, installed on the accelerator pedal support rod 22, used to limit the maximum travel of the accelerator pedal. The limiter has a compact overall structure, is easy to install, and can quickly limit and release the accelerator travel without altering the original vehicle structure. The accelerator pedal limiter mainly includes a fixed mounting assembly 1, a limit support assembly 2, a locking assembly 3, and an elastic reset component 4.

[0024] The fixed mounting assembly 1 is used to reliably fix the entire limiter to the accelerator pedal support rod 22 and serves as the mounting base for this device. This assembly can accommodate pedal support rods 22 of different sizes, and its adjustable clamping structure ensures secure installation and easy assembly / disassembly.

[0025] The limiting support assembly 2 is the main actuator for limiting the throttle travel in this device. This assembly includes a support plate 21 and a support rod 22 fixed to the support plate 21. The support plate 21 is rotatably connected to the mounting bracket 11 via a transverse pivot, and the support rod 22 rotates synchronously with the support plate 21. Through the rotation of the support plate 21, the support rod 22 can switch between a limited and non-limited state. In the limited state, the end of the support rod 22 abuts against the vehicle floor to limit the maximum downward travel of the accelerator pedal. In the non-limited state, the end of the support rod 22 detaches from the floor, without affecting the normal operation of the pedal.

[0026] The locking component 3 is used to lock and release the limiting state of the limiting support component 2. This component is located between the support plate 21 and the mounting bracket 11, and includes a locking plate 31 and a locking rod 32. The locking plate 31 has a limiting groove 33. When the driver moves the locking rod 32 with their foot, the locking rod 32 moves along the guide direction and engages with the limiting groove 33, thus keeping the support plate 21 and the support rod 22 in the limited position. When the locking rod 32 is moved again to disengage from the limiting groove 33, the support plate 21 and the support rod 22 can return to the non-limited state, achieving rapid switching.

[0027] An elastic reset component 4 is disposed between the mounting bracket 11 and the support plate 21. It applies a reset torque to the support plate 21 after unlocking, causing it to automatically return to the non-limited state. This component can employ a tension spring or torsion spring structure. It stores energy when the support plate 21 rotates to the limit state and releases energy when the locking lever 32 exits the limit groove 33, thereby driving the support plate 21, support lever 22, and locking lever 32 to reset as a whole. Through the cooperation of the above components, the accelerator pedal limiter of this embodiment can quickly switch between the limit and unlocked states by the driver lightly touching or moving the locking lever 32, without manual operation or disassembly, greatly improving ease of use and safety.

[0028] Reference Figure 2 The fixed mounting assembly 1 includes a mounting bracket 11, which has mounting holes for fitting onto the accelerator pedal support rod 22. In one specific embodiment, the mounting bracket 11 includes a U-shaped clamping plate 111 and locking bolts 112 passing through the two free ends of the clamping plate 111, with the mounting holes formed between the locking bolts 112 and the clamping plate 111. The opening size of the mounting hole can be finely adjusted by tightening or loosening the locking bolts 112 to accommodate accelerator pedal support rods 22 of different diameters, achieving a stable clamping effect.

[0029] To further improve the stability of the connection, a fixing bolt is threaded onto the clamping plate 111. This fixing bolt passes through the clamping plate 111 from the outside to the inside, and its inner end can abut against the outer wall of the accelerator pedal support rod 22. Through the tightening action of this fixing bolt, the limiter can be effectively prevented from rotating or displacing during vehicle vibration or frequent operation, thereby enhancing the reliability of installation.

[0030] During installation, the operator places the U-shaped clamping plate 111 onto the support rod 22 from the outside of the accelerator pedal support rod 22, positioning the support rod 22 within the clamping space. Then, the locking bolt 112 is tightened, gradually converging the two free ends of the clamping plate 111 to achieve initial fixation. Subsequently, the fixing bolts on the clamping plate 111 are screwed in and tightened, causing their ends to press against the surface of the support rod 22, achieving double clamping fixation. Through this structural design, the mounting bracket 11 of this embodiment can be quickly installed without welding, drilling, or modifying the original vehicle structure. It possesses excellent versatility and vibration resistance, is suitable for different vehicle models and various accelerator pedal structures, and ensures that the limiter maintains a stable connection even under long-term vehicle operation.

[0031] Reference Figure 1 and Figure 2The limiting support assembly 2 includes a support plate 21 and a support rod 22 fixed on the support plate 21. The support plate 21 is rotatably engaged with the mounting bracket 11 via a laterally arranged rotational central axis, allowing the support plate 21 to be angled around the lateral axis, thereby driving the support rod 22 to rotate synchronously. The support rod 22 is arranged along the normal direction of the support plate 21, and its axis is substantially perpendicular to the plane of the support plate 21.

[0032] In this embodiment, when the support plate 21 rotates downwards around the transverse rotation center axis to the vertical direction, the end of the support rod 22 abuts against the vehicle floor, forming a limiting state. At this time, the travel of the accelerator pedal during depressing is limited by the support rod 22, and the maximum downward distance of the pedal is determined by the distance between the bottom end of the support rod 22 and the floor, thereby achieving precise limitation of the accelerator travel. When the support plate 21 rotates in the opposite direction around the transverse axis to the upper or outer side, the end of the support rod 22 disengages from the vehicle floor and is in a non-limiting state. At this time, the accelerator pedal can be freely depressed according to the normal travel and is no longer subject to limiting constraints.

[0033] With the above structural design, the support plate 21 and support rod 22 can quickly switch between limited and non-limited states through simple rotational movement. When in use, the driver only needs to move the locking lever 32 with their foot to control the rotation of the support plate 21, thus freely switching between the two working states. Simultaneously, in conjunction with the action of the locking component 3 and the elastic reset component 4, when the lock is released, the support plate 21 and support rod 22 can automatically reset to the non-limited position under the action of elastic force, realizing automated locking and reset functions.

[0034] Furthermore, in one specific embodiment, the support rod 22 and the support plate 21 adopt a threaded engagement structure. The length of the support rod 22 extending out of the support plate 21 can be changed by rotation, thereby adjusting the distance between the end of the support rod 22 and the vehicle floor, thus precisely controlling the maximum travel limit of the accelerator pedal. This adjustment method is simple in structure, flexible in adjustment, and suitable for adjusting the limit depth under different driver or training needs.

[0035] In another embodiment, the support plate 21 includes a connecting portion and a mounting portion, with the mounting portion arranged perpendicularly to the connecting portion. A mounting portion is provided at each end of the connecting portion. A support rod 22 is threaded onto one of the mounting portions to abut against the vehicle floor, providing a limiting effect; a locking rod 32 is mounted on the other mounting portion to achieve a locking function. This arrangement results in a more compact structural layout, less installation space, and stronger overall rigidity.

[0036] The locking assembly 3 includes a locking plate 31 and a locking rod 32. The locking plate 31 is fixedly mounted on the mounting bracket 11 and has a limiting groove 33 on its surface. The locking rod 32 is mounted on the support plate 21 and rotates synchronously with the support plate 21. When the support plate 21 rotates to the limiting state, the locking rod 32 can be engaged in the limiting groove 33 to lock the support plate 21, thereby maintaining the limiting position of the support rod 22 stably and reliably.

[0037] The locking plate 31 is provided with a guide groove 34 communicating with the limiting groove 33. The guide groove 34 is arranged perpendicularly to the limiting groove 33 and is used to guide the locking rod 32 into the limiting groove 33. The locking rod 32 includes a base 321 and a rod 322. The base 321 is fixed on the support plate 21, and the rod 322 is rotatably connected to the base 321. Guided by the guide groove 34, when the driver operates the locking rod 32, the rod 322 can slide along the direction of the guide groove 34 and accurately enter the limiting groove 33 to complete the limiting locking action.

[0038] Reference Figure 3 In one embodiment, the locking lever 32 is offset relative to the guide groove 34. When the locking lever 32 slides within the guide groove 34, the lever body 322 is compressed by the sidewall of the guide groove 34, causing it to rotate and tilt at a certain angle, naturally causing the front end of the lever body 322 to deviate towards the limiting groove 33. This offset design helps the locking lever 32 to smoothly engage when it slides to the position of the limiting groove 33, thereby improving the smoothness and reliability of the locking process. Figure 3 As shown, this offset fit structure makes the locking action smoother and avoids misfitting or jamming.

[0039] In one embodiment, the limiting groove 33 has an anti-detachment protrusion 35 on the side near the guide groove 34, and the anti-detachment protrusion 35 and the side wall of the limiting groove 33 form an arc transition. With this anti-detachment structure, when the locking rod 32 is engaged in the limiting groove 33, the end of its rod body 322 is limited by the arc transition surface, which can prevent the locking rod 32 from accidentally disengaging even in the event of vehicle vibration or accidental foot contact, further ensuring the stability and safety in the limited state.

[0040] In one embodiment, a pedal is provided at the end of the locking lever 32 away from the support plate 21, and the pedal is arranged at a preset angle with the locking lever 32. The driver can move the pedal with his foot to slide the locking lever 32 into or out of the limiting groove 33 along the guide groove 34, thereby achieving a quick switch between the limiting and unlocking states. The size and tilt angle of the pedal are designed according to ergonomics, allowing the driver to complete the operation with a natural foot posture, without bending over or using tools to lock and unlock.

[0041] In one embodiment, the elastic reset member 4 is a spring structure. One end of the spring is connected to the support plate 21, and the other end is connected to the locking plate 31, with the connection points on both sides of the rotation center of the support plate 21. When the support rod 22 is in the non-limited state, the spring is in the initial state; when the support rod 22 rotates to the limited state, the spring is stretched and stores elastic energy, applying a torsional force to the support plate 21, so that the support plate 21 always has a tendency to reset in the non-limited direction. At the same time, the stretching direction of the spring also provides a component force to the support plate 21, causing the locking rod 32 to move towards the limiting groove 33, so that the locking rod 32 can smoothly enter the limiting groove 33 to achieve locking. Through this structural design, the spring has the dual functions of auxiliary locking and automatic reset throughout the entire working process.

[0042] When the limit switch is released, after the driver's foot moves the locking lever 32 out of the limit slot 33, the spring releases its stored elastic energy, driving the support plate 21, support rod 22, and locking lever 32 to rotate in the opposite direction, thereby automatically resetting to the non-limited state. Through this reset structure, the limit switch can quickly return to its initial position after the lock is released, without the need for manual reset.

[0043] In another embodiment, the elastic reset element 4 is a torsion spring structure. A rotating shaft is provided on the support plate 21, and the torsion spring is sleeved on the outer circumference of the rotating shaft. The two ends of the torsion spring are connected to the support plate 21 and the locking plate 31, respectively. When the support plate 21 rotates to the limit position, the torsion spring is torsionally charged and stores energy; when the lock is released, the torsion spring releases its torque, providing a reset torque for the support plate 21, thereby driving the support rod 22 back to the non-limit position. The torsion spring structure allows for stable torsional reset within a limited space, resulting in a compact structure and sensitive response.

[0044] In one embodiment, the end of the support rod 22 furthest from the support plate 21 is provided with an elastic support head 23. This elastic support head 23 is used to contact the vehicle floor when the support rod 22 is in the limited position, providing cushioning, anti-slip, and vibration damping. Specifically, the elastic support head 23 can be made of rubber or a similarly elastic polymer material with moderate hardness. It can provide stable support when the accelerator pedal is under force, and can also absorb some of the impact force through its own elastic deformation, avoiding noise or wear caused by direct hard contact between the metal support rod 22 and the floor. Furthermore, the elastic support head 23 has a high coefficient of friction, preventing the support rod 22 from slipping during vehicle vibration or repeated pedal operation, thereby further improving the stability and reliability of the limiting structure.

[0045] Reference Figure 3 and Figure 4The implementation principle of the accelerator pedal limiter in this embodiment is as follows: After the limiter is installed on the accelerator pedal support rod 22, the driver can control the switching between the limited and non-limited states by operating the locking rod 32 with their foot. Specifically, the driver moves the locking rod 32 with their foot, causing it to move along the guide groove 34 and enter the limiting groove 33. With the cooperation of the elastic reset member 4, the support plate 21 rotates synchronously with the locking rod 32, causing the support rod 22 to rotate from a horizontal position to a vertical position. At this time, the bottom end of the support rod 22 abuts against the vehicle floor, forming a mechanical limit on the accelerator pedal. The distance between its bottom end and the floor is the maximum depressing stroke of the accelerator pedal, thereby effectively limiting the acceleration depth of the pedal.

[0046] During this process, the spring in the elastic reset member 4 is stretched and stores elastic energy, applying a torsional force to the support plate 21, causing the support plate 21 to tend to reset in the non-limiting direction. It is worth noting that the stretching direction of the spring also provides a component force to the support plate 21, causing the locking rod 32 to move towards the limiting groove 33, so that the locking rod 32 can smoothly enter the limiting groove 33 to achieve locking.

[0047] When the limit needs to be released, the driver uses their foot to move the locking lever 32 again, causing the locking lever 32 to exit the limit groove 33. At this time, the elastic reset member 4 releases the stored elastic energy, driving the support plate 21, support rod 22 and locking lever 32 to rotate in the opposite direction as a whole, automatically returning to the non-limited state. In this state, the bottom end of the support rod 22 is detached from the base plate, and the accelerator pedal can be pressed freely according to the normal stroke, without being restricted.

[0048] The entire limiting and releasing process can be completed by foot operation, without the need for manual insertion or removal of pins or adjustment of the limiting component position, making operation simple and responsive. Through the synergistic action of locking component 3 and elastic reset component 4, this embodiment achieves automatic locking, rapid release, and self-reset functions of the limit, making accelerator pedal travel control more efficient, safe, and reliable.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
