Description

Technical Field

[0001] The present invention relates to the technical field of automotive pedal assemblies, and particularly to a novel electronic throttle acceleration pedal assembly. Background Art

[0002] With the continuous development of the automotive industry, the safety and driving comfort of automobiles have gradually become the focus of consumers' attention. Especially in modern automobiles, as an important driving control device, the performance of the electronic throttle acceleration pedal directly affects the driver's operating experience and driving safety. However, the existing automotive throttle acceleration pedal assemblies have certain deficiencies in multiple aspects and urgently need improvement.

[0003] The traditional throttle acceleration pedal system cannot effectively cooperate with the vehicle's visual warning system and other auxiliary driving systems (such as obstacle detection, collision warning, reverse image system, etc.). This makes it possible for the driver to cause the vehicle to accelerate unexpectedly or collide with surrounding obstacles due to slow reaction when driving at low speed or reversing, posing a potential hazard to driving safety. Especially when reversing in a complex urban environment or a parking lot, the driver often faces greater operating pressure. Therefore, how to limit the vehicle's acceleration in these situations and avoid the occurrence of accidents has become an urgent technical problem to be solved.

[0004] The existing pedal design cannot provide an optimized control experience according to the personalized needs of the driver. The existing electronic throttle acceleration pedal systems generally adopt a fixed friction resistance design and cannot adjust the feedback force of the pedal in real time according to the driver's operating habits and needs. This may cause the pedal response to be too sensitive or insensitive, affecting the driver's control of the acceleration process, and even may lead to driving mistakes due to inappropriate feedback force, posing a safety hazard.

[0005] There is a need for a new throttle acceleration pedal assembly that can overcome the deficiencies of the existing technology, combine the visual warning system and other intelligent auxiliary driving technologies, monitor the surrounding environment in real time, and intelligently adjust the pedal rotation angle to prevent unexpected acceleration and collisions. At the same time, the new pedal system also needs to have higher flexibility and adjustability to ensure the driver's comfortable experience and precise control in different driving scenarios, and further improve driving safety and comfort. Summary of the Invention

[0006] The purpose of the present invention is to provide a novel electronic throttle acceleration pedal assembly to solve the problems raised in the background art above and overcome the existing technical defects.

[0007] The present invention provides a new type of electronic throttle accelerator pedal assembly. Through the cooperation of a speed limit gear ring, a speed limit groove, a speed limit block and a visual warning system, combined with an obstacle detection, a collision warning and a reverse image system, the present invention can monitor the surrounding environment in real time, limit the rotation angle of the pedal, control the vehicle speed, avoid accidental acceleration or hitting an obstacle due to the driver's slow reaction during low-speed driving or reversing, improve driving safety, and reduce accidents caused by driving negligence. At the same time, the elliptical groove, the circular groove and the elliptical plate adjust the frictional resistance of the pedal rotation, ensuring that the driver steps on the pedal with moderate force, avoiding being overly sensitive or insensitive in response. The tightening and loosening member uniformly adjusts the frictional force on the production line and provides accurate feedback. The driver can adjust the pedal force in real time through the central control screen to ensure driving comfort and safety, and reduce operation errors caused by improper frictional force.

Detailed implementation manners

[0046] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, those of ordinary skill in the art can propose various mutually replaceable structural forms and implementation methods. Therefore, the following specific embodiments and the accompanying drawings are only exemplary illustrations of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0047] As Figures 1 to 11 shown, an embodiment of the present invention provides a new type of electronic throttle accelerator pedal assembly, including: a pedal 1 and a pedal box 2 arranged below the pedal 1, characterized in that it further includes:

[0048] A rotating shaft 3, one end of which is fixed below the pedal 1 and the other end is rotatably inserted into the pedal box 2; a tightening member 4, fixed on the pedal box 2 and the rotating shaft 3, for adjusting the frictional resistance degree of the rotation of the pedal 1; a speed limiting member 5, fixed in the pedal box 2, for cooperating with the vehicle vision warning system to intelligently limit the rotation angle of the accelerator pedal 1; an angle measuring member 6, rotatably arranged on the pedal box 2, for detecting the rotation angle of the pedal 1 to control the acceleration degree.

[0049] The tightening member 4 includes: an elliptical groove 401, opened on the rotating shaft 3; a circular groove 402, opened on the rotating shaft 3 and communicated with the elliptical groove 401; an elliptical plate 403, rotatably arranged in the circular groove 402; the speed limiting member 5 includes: a speed limiting gear ring 501, rotatably sleeved on the rotating shaft 3; a speed limiting groove 502, opened on the inner side of the speed limiting gear ring 501; a speed limiting block 503, fixed on the rotating shaft 3 and located in the speed limiting groove 502.

[0050] A mounting plate 201 is fixed below the pedal box 2, and the mounting plate 201 is provided with mounting holes 202; it further includes: a controller 7, fixed in the pedal box 2; a data line 8, one end of which is fixed on the controller 7 and the other end extends out of the pedal box 2; a data interface 9, fixed on the end extending out of the pedal box 2.

[0051] Specifically, the tightening member 4 is used to adjust the frictional resistance of the rotation of the adjustable pedal 1; on the production line, the tightening member 4 can uniformly adjust the frictional force received by the pedal 1 when rotating on the pedal box 2, so as to accurately control the force required for the driver to step on the pedal 1; this design can effectively avoid the pedal 1 from being too sensitive or insensitive in response, ensuring that the driver can obtain a more appropriate feedback during operation; two adjustment motors are provided on both sides of the tightening member 4, and the driver can adjust the required stepping force of the pedal 1 in real time through the central control operation screen; this adjustment function not only improves the driving comfort, but also avoids improper operation caused by too large or too small frictional resistance, thereby reducing driving errors caused by improper force and ensuring a safe driving experience.

[0052] The speed limiter 5 cooperates intelligently with the automobile visual warning system to effectively control the vehicle's driving speed by limiting the rotation angle of the accelerator pedal 1; the speed limiter 5 is combined with the obstacle detection system, the collision warning system and the reversing image system to monitor the surrounding environment in real time; when the system detects the distance to the obstacle and the vehicle is in a low-speed state, the speed limiter 5 automatically limits the rotation angle of the accelerator pedal 1, thereby limiting the vehicle's acceleration ability; this design effectively avoids the risk of accidental acceleration of the vehicle due to excessive stepping on the pedal 1 when the driver is in a poor state or slow to react, especially when reversing or driving at a low speed, reducing the possibility of the vehicle colliding with obstacles; through this intelligent control system, driving safety can be improved and collision accidents caused by driver negligence can be reduced.

[0053] As a preferred embodiment of the present invention, the tensioner 4 also includes: a first torsion spring 404, one end of which is fixed on the pedal 1 and the other end is fixed in the pedal box 2; a spring ring seat 405, which is fixed on the rotating shaft 3; a second torsion spring 406, one end of which is fixed on the spring ring seat 405 and the other end is fixed in the pedal box 2; the tensioner 4 also includes: tension grooves 407, which are provided on both sides of the pedal box 2; an elastic plate 408, which is fixed in the elastic groove 407; an elastic tube 409, one end of which is fixed on the elastic plate 408 and the other end extends into the elliptical groove 401; an elastic threaded rod 4010, which is threadedly inserted in the elastic tube 409 and one end of which extends into the elliptical groove 401 is fixed on the elliptical plate 403; a hexagonal groove 4011, which is provided on the elastic threaded rod 4010; a bolt 4012, which is slidably inserted in the elastic plate 408 and the threaded end is threaded into the pedal box 2.

[0054] Specifically, the first torsion spring 404 and the second torsion spring 406 are used to provide elastic reset for the pedal 1 when it rotates; by screwing the tightening threaded rod 4010 in or out of the tightening tube 409, the tightness between the tightening plate 408 and the inner wall of the circular groove 402 is adjusted, thereby increasing or decreasing the friction force, and adjusting the force required for the pedal 1 to rotate on the pedal box 2.

[0055] As a preferred embodiment of the present invention, the speed-limiting member 5 further includes: a fixing ring 504 fixed inside the pedal box 2; a rotating ring 505 with one end fixed to the speed-limiting gear ring 501 and the other end rotatably inserted into the fixing ring 504; a motor base 506 fixed inside the pedal box 2; a limiting angle rod 507 fixed inside the pedal box 2; the speed-limiting member 5 further includes: a locking pawl 508 rotatably arranged inside the pedal box 2 with its tip inserted into the tooth groove of the speed-limiting gear ring 501; a sliding plate 509 fixed inside the pedal box 2; a sliding groove 5010 formed on the sliding plate 509; a slider 5011 slidably inserted into the sliding groove 5010; an unlocking tooth 5012 with its tooth base fixed to the slider 5011; an unlocking spring 5013 with one end fixed to the locking pawl 508 and the other end fixed to the unlocking tooth 5012; the speed-limiting member 5 further includes: a speed-limiting motor 5014 fixed to the motor base 506; a speed-limiting shaft 5015 with one end fixed to the rotating shaft of the speed-limiting motor 5014 and the other end rotatably inserted into the pedal box 2; a speed-limiting gear 5016 fixed to the speed-limiting shaft 5015 and meshing with the speed-limiting gear ring 501 and the unlocking tooth 5012.

[0056] As a preferred embodiment of the present invention, the angle measuring member 6 includes: an angle measuring tooth group 601 fixed to the pedal 1; a first angle measuring shaft 602 rotatably arranged on the pedal box 2; a first angle measuring gear 603 fixed to the first angle measuring shaft 602 and meshing with the angle measuring tooth group 601; a first angle sensor 604 fixedly sleeved on the first angle measuring shaft 602 and fixed inside the pedal box 2; the angle measuring member 6 further includes: a second angle measuring shaft 605 rotatably arranged inside the pedal box 2; a second angle measuring gear 606 fixed to the second angle measuring shaft 605 and meshing with the speed-limiting gear ring 501; a second angle sensor 607 fixedly sleeved on the second angle measuring shaft 605 and fixed inside the pedal box 2.

[0057] Specifically, the first angle sensor 604 is used to detect the rotation angle of the pedal 1 and the first angle measuring shaft 602, so as to control the acceleration of the vehicle; the second angle sensor 607 is used to detect the rotation angle of the speed-limiting gear ring 501, so as to control the rotation angle of the speed-limiting gear ring 501.

[0058] Working principle: On the factory production line, by inserting a hexagonal wrench into the hexagonal groove 4011, the rotation of the hexagonal wrench drives the tightening and loosening threaded rod 4010 to screw in or out in the tightening and loosening cylinder 409, adjusting the tightness between the tightening plate 408 and the inner wall of the circular groove 402, thereby increasing or decreasing the frictional force and adjusting the force required for the pedal 1 to rotate on the pedal box 2; the tightening plate 408 is fixedly installed in the tightening groove 407 through bolts 4012, and the tightening plate 408, the tightening and loosening cylinder 409, the tightening and loosening threaded rod 4010 and the elliptical plate 403 play a role in fixing the rotating shaft 3.

[0059] Start the speed-limiting motor 5014. The rotation of the speed-limiting motor 5014 drives the rotation of the speed-limiting shaft 5015. The rotation of the speed-limiting shaft 5015 drives the rotation of the speed-limiting gear 5016. The rotation of the speed-limiting gear 5016 drives the rotation of the speed-limiting gear ring 501. The speed-limiting groove 502 of the speed-limiting gear ring 501 reduces the interval between the speed-limiting block 503. The speed-limiting block 503, the rotating shaft 3 and the pedal 1 are fixed together, and the rotatable angle of the opposite pedal 1 is reduced; the rotation of the speed-limiting gear 5016 pushes the unlocking tooth 5012 to slide on the sliding plate 509, leaving a moving space for the rotation of the speed-limiting gear 5016.

[0060] The locking pawl 508 performs one-way locking on the speed-limiting gear ring 501. When the speed-limiting gear ring 501 reduces the rotation angle of the rotating shaft 3, the speed-limiting gear ring 501 can pass through the locking of the locking pawl 508 without hindrance; when the speed-limiting block 503, the rotating shaft 3 and the pedal 1 rotate at an accelerated speed, the speed-limiting block 503 abuts against the groove wall of the speed-limiting groove 502, and the locking pawl 508 locks the speed-limiting gear ring 501 in the reverse direction.

[0061] When the speed-limiting motor 5014 starts in the reverse direction, the speed-limiting gear 5016 rotates in the reverse direction; at this time, the speed-limiting gear 5016 and the unlocking tooth 5012 are in a meshed state until the unlocking tooth 5012 slides to the other side of the sliding plate 509. At this time, the rotation of the speed-limiting gear 5016 pushes the unlocking tooth 5012 outward; when the unlocking tooth 5012 moves to the other side of the sliding plate 509, the unlocking spring 5013 will pull the locking pawl 508 out of the tooth groove of the speed-limiting gear ring 501, and the speed-limiting gear 5016 can be reset in the reverse direction; when resetting the unlocking tooth 5012, the speed-limiting motor 5014 rotates, driving the rotation of the speed-limiting gear 5016, and the rotation of the speed-limiting gear 5016 drives the unlocking tooth 5012 to return to the initial position.

[0062] There is a margin for movement between the speed-limiting groove 502 and the speed-limiting block 503. The first angle sensor 604 and the second angle sensor 607 continuously monitor the rotation angles of the pedal 1 and the speed-limiting gear ring 501 to prevent conflicts between the speed-limiting block 503 of the pedal 1 stepped on by the driver and the speed-limiting groove 502 of the speed-limiting gear ring 501. For example, when the obstacle detection system, the collision warning system and the reverse image system detect safety, if the speed-limiting groove 502 still limits the rotation angle of the pedal 1, the speed-limiting motor 5014 will be started in the reverse direction to reset the speed-limiting gear 5016; the speed-limiting gear ring 501 is meshed with the speed-limiting gear 5016, and the rotation of the speed-limiting gear 5016 can control the angle of the speed-limiting gear ring 501; there is a rotatable margin for the angle of the unlocking tooth 5012 passing through the speed-limiting gear 5016 between the speed-limiting groove 502 and the speed-limiting block 503.

[0063] The start of the speed limiting motor 5014 drives the speed limiting shaft 5015 to rotate, which in turn drives the speed limiting gear 5016 to rotate, and the speed limiting gear 5016 further drives the speed limiting gear ring 501 to rotate; this series of rotations ensures that the speed limiting gear ring 501 adjusts the rotation angle of the pedal 1 through the speed limiting groove 502 and the speed limiting block 503; when the speed limiting gear ring 501 rotates, the interval of the speed limiting groove 502 is reduced, thereby limiting the rotation angle of the pedal 1, ensuring that the rotation of the pedal 1 does not exceed the preset range.

[0064] The locking pawl 508 effectively performs one-way locking on the speed limiting toothed ring 501, ensuring that when the speed limiting toothed ring 501 contracts, the locking pawl 508 can be stably locked to avoid unnecessary reverse movement; and, when the speed limiting block 503 rests against the groove wall of the speed limiting groove 502, the locking pawl 508 plays a reverse locking role, further ensuring the stability of the speed limiting mechanism.

[0065] The unlocking tooth 5012 is meshed with the speed limiting gear 5016, and when the speed limiting motor 5014 is started in reverse, the unlocking tooth 5012 is pushed to slide to the other side of the slide plate 509 by the rotation of the speed limiting gear 5016. This process ensures the sliding space of the unlocking tooth 5012, thereby avoiding the system from being stuck. The rotation of the speed limiting gear 5016 enables the angle of the speed limiting gear ring 501 to be accurately controlled.

[0066] The first angle sensor 604 and the second angle sensor 607 monitor the rotation angle of the pedal 1 and the speed limiting gear ring 501 in real time, avoiding the conflict between the speed limiting groove 502 and the speed limiting block 503 caused by external factors (such as obstacles or system failures), thereby ensuring the safety and stability of the system in actual use.

[0067] When the speed limiting motor 5014 is started in reverse, the speed limiting gear 5016 rotates in reverse, pushing the interaction between the unlocking tooth 5012 and the sliding plate 509 until the unlocking tooth 5012 slides to the other side. At this time, the unlocking spring 5013 pulls the locking pawl 508 to disengage the tooth groove of the speed limiting gear ring 501, thereby allowing the speed limiting gear 5016 to reset in reverse.

[0068] When the unlocking tooth 5012 moves to the other side of the sliding plate 509, the rotation of the speed limiting gear 5016 will push the unlocking tooth 5012 outward, and at the same time, the unlocking spring 5013 will pull the locking pawl 508 out of the tooth groove to release the locked state. In this way, the speed limiting gear 5016 can smoothly complete the reverse reset, and the speed limiting gear ring 501 returns to its original state.

[0069] The proper margin design between the speed limit slot 502 and the speed limit block 503 ensures that during reverse operation, the speed limit gear ring 501 and the speed limit gear 5016 can be reset without obstruction; even during reverse startup, the sliding of the unlocking tooth 5012 and the mechanism of the spring pulling the locking pawl 508 can ensure that the entire speed limit system can return to its original state, avoiding jamming or system failures.

[0070] During the reset process, the speed limit motor 5014 drives the speed limit gear 5016 by rotating and ensures that the unlocking tooth 5012 returns to its initial position, so that the speed limit gear ring 501 and the speed limit slot 502 can be perfectly matched to achieve a complete reset of the system.

[0071] The controller 7, the data line 8 and the data interface 9 are used to connect to the central control of the vehicle. The controller 7 is used to control the speed limit motor 5014, the first angle sensor 604 and the second angle sensor 607; the first angle sensor 604 detects the angle of rotation of the pedal 1 to control acceleration or deceleration.

[0072] The technical scope of the present invention is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
