Technical Field
[0001] The utility model relates to the technical field of vehicle pedals, in particular to a pedal assembly for vehicles, which can be applied to vehicles. Background Art
[0002] The vehicle pedal assembly mainly includes three parts, namely: the accelerator pedal assembly: the pedal used by the driver to control the engine speed. When the accelerator pedal is depressed, the fuel supply of the engine increases and the vehicle speed increases; when the accelerator pedal is released, the fuel supply decreases and the vehicle speed decreases. The brake pedal assembly: the control device used by the driver to decelerate or stop the vehicle. When the brake pedal is depressed, the braking system works and the vehicle decelerates until it stops. The clutch pedal assembly: mainly used for manual transmission vehicles. When shifting gears, the driver needs to depress the clutch pedal to disconnect the connection between the engine and the transmission to ensure the stability and safety of gear shifting.
[0003] Therefore, the prior art has designed a wire-controlled pedal for vehicles. However, in the prior art, the sensor is integrated on one of the pedal arm and the pedal bracket. When the sensor on the pedal arm or the pedal bracket fails, signal redundancy cannot be achieved, and the stroke of the pedal arm cannot be detected, reducing the safety performance of the vehicle.
[0004] For example, Chinese invention patent CN109204254B discloses a vehicle and its electronic brake pedal device. The electronic brake pedal device includes: a booster, the booster having a push rod; a brake pedal, the brake pedal including a pedal arm, the pedal arm having a first surface and a second surface disposed opposite to each other; a brake decoupling mechanism, the brake decoupling mechanism including a first driver and a first driving rod, the first driver being connected to the first driving rod to drive the first driving rod to reciprocate, the first driving rod being rotatably connected to the first surface, the first driving rod being movable relative to the push rod; an electronic force feedback mechanism, the electronic force feedback mechanism including a second driver and a second driving rod, the second driver being connected to the second driving rod to drive the second driving rod to reciprocate, the second driving rod being connected to the second surface; a detection device for detecting the braking depth of the brake pedal. In this patent, only a position detection device is provided at the position of the pedal arm. However, if this detection device is damaged, the controller will not be able to detect the pedal stroke. Therefore, there are potential safety hazards and the safety performance of the whole vehicle is reduced.
[0005] Therefore, when the sensors on the pedal arm or the pedal bracket of the vehicle pedal in the prior art both fail, the stroke of the pedal arm cannot be detected, thus reducing the safety performance of the vehicle. Summary of the Utility Model

And by setting two rotation angle detection components and using electronic signals to transmit the travel of the pedal arm, the response speed of the pedal assembly for a vehicle is also greatly improved.
[0012] Furthermore, the first rotation angle detection component can drive the second rotation angle detection component to rotate synchronously, and their positions are close and integrated together, reducing the occupation of the vehicle occupant compartment space by the pedal assembly for a vehicle.

[0075] Automobile pedals include a brake pedal, an accelerator pedal, a clutch pedal, etc. Taking the brake pedal as an example, most of them are mainly hydraulic braking. The comprehensive cost of the hydraulic braking device is relatively high, and at the same time, the structure is complex. The comfort of the driver stepping on the pedal will gradually deteriorate as the hydraulic oil decreases, and in addition, the inspection may not be in place when a failure occurs during stepping, which may cause potential safety hazards.
[0076] Therefore, the prior art has designed a wire-controlled pedal for automobiles. However, in the prior art, the sensor is integrated on one of the pedal arm and the pedal bracket. When the sensor on the pedal arm or the pedal bracket fails, signal redundancy cannot be achieved, and the stroke of the pedal arm cannot be detected, reducing the safety performance of the automobile. For example, taking the brake pedal as an example, if the pedal stroke cannot be detected, it is very easy to occur safety accidents, such as brake failure. Therefore, how to improve the safety performance of the automobile pedal assembly has become an urgent problem to be solved.
[0077] To solve the above technical problems, the present utility model provides a pedal assembly for an automobile. The pedal assembly for an automobile is provided with a first corner detection component and a second corner detection component, which are respectively located on the pedal arm and the pedal base, and the rotation of the first corner detection component can drive the rotation of the second corner detection component to monitor the displacement of the pedal arm and output two independent displacement signals, so as to achieve signal redundancy. And when a problem occurs in one of the signals, and the first corner detection component on the pedal arm or the second corner detection component on the pedal base is damaged during the repair or use of the pedal base or the pedal arm, there is still one signal working normally, improving the safety performance of the automobile and ensuring the realization of the functions of the pedal assembly for the automobile and the safety of passengers.
[0078] To make the purpose, technical solution and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to the accompanying drawings.
[0079] As Figure 1 and Figure 2 shown, the embodiment of the present utility model discloses a pedal assembly for an automobile, including: a pedal base 1, a pedal arm 2 rotatably connected to the pedal base 1, a first corner detection component 3, a second corner detection component 4 and a pedal plug-in 5. Among them, one end of the pedal arm 2 is provided with a rotation connection portion 20, and a connection cavity 10 adapted to the rotation connection portion 20 is formed on the pedal base 1, and the rotation connection portion 20 is rotatably connected in the connection cavity 10.
[0080] Furthermore, the first rotation angle detection component 3 is arranged on the rotation connection part 20 and can rotate synchronously with the rotation connection part 20 to detect the rotation angle of the rotation connection part 20; the second rotation angle detection component 4 is rotatably arranged in the connection cavity 10, and the rotation of the first rotation angle detection component 3 can drive the second rotation angle detection component 4 to rotate, so as to realize signal output.
[0081] Furthermore, the pedal plug-in part 5 is fixedly connected to the pedal base 1 and is electrically connected to the first rotation angle detection component 3 and the second rotation angle detection component 4 respectively, so as to ensure that the pedal plug-in part 5 does not shake when outputting signals, and ensure the stability of signal output.
[0082] Specifically, the working principle of the pedal assembly for an automobile provided in this embodiment is as follows:
[0083] During the process when a driver drives an automobile and steps on the pedal arm 2, the pedal arm 2 rotates through the rotation connection part 20. At this time, the rotation connection part 20 drives the first rotation angle detection component 3 to rotate. At the same time, the first rotation angle detection component 3 drives the second rotation angle detection component 4 to rotate synchronously, so as to output two independent rotation angle signals of the pedal arm 2, obtain the displacement stroke of the pedal arm 2, and further achieve signal redundancy, improving the safety performance of the automobile. And when a problem occurs in one of the signals, such as the first rotation angle detection component 3 on the pedal arm 2 or the second rotation angle detection component 4 on the pedal base 2 is damaged during maintenance or the use of the pedal base 1 or the pedal arm 2, there is still one path working normally, thus improving the safety performance of the automobile, ensuring the realization of the function of the pedal assembly for the automobile, and the safety of passengers.
[0084] Furthermore, the first rotation angle detection component 3 can drive the second rotation angle detection component 4 to rotate synchronously. The positions of the two are close and integrated together, reducing the occupation of the space of the automobile passenger compartment by the pedal assembly for the automobile. And because the connection cavity 10 is provided on the pedal base 1 to accommodate part of the pedal arm 2, on the one hand, the size of the pedal assembly for the automobile is reduced, thereby reducing the occupation of the automobile space by the pedal plug-in part 5 for the automobile, and on the other hand, it also has a protective effect on the first rotation angle detection component 3 and the second rotation angle detection component 4.
[0085] In summary, in the pedal assembly for an automobile, the pedal arm 2 is a dynamic structural member that often undergoes displacement, the pedal base 1 is a static structural member that does not move, the first rotation angle detection component 3 is located on the pedal arm 2, and the second rotation angle detection component 4 is located on the pedal base 1; when the pedal arm 2 of the pedal assembly for an automobile rotates, the first rotation angle detection component 3 located on the pedal arm 2 can drive the second rotation angle detection component 4 on the static structural member pedal base 1 to rotate synchronously, outputting two independent pedal arm 2 rotation angle signals, achieving signal redundancy, and the signal output is stable, ensuring the realization of the pedal function, improving the safety of the vehicle, and at the same time greatly improving the response speed of the pedal, reducing the risk that when a problem occurs in one of the signals, such as when the first rotation angle detection component 3 on the pedal arm 2 or the second rotation angle detection component 4 on the pedal base 1 is damaged during the repair or use of the pedal base 1 or the pedal arm 2, the stroke of the pedal arm 2 cannot be detected.
[0086] It should be understood that when the second rotation angle detection component 4 is located in the connection cavity 10 formed on the pedal base 1, the second rotation angle detection component 4 should be installed on the pedal base 1.
[0087] Next, an explanation will be given on how to achieve the synchronous linkage of the rotation of the second rotation angle detection component 4 when the first rotation angle detection component 3 rotates and the transmission method between the two.
[0088] As Figures 1 - 3 shown, in the implementation manner disclosed in this embodiment, the pedal assembly for an automobile further includes a transmission component 6. When the first rotation angle detection component 3 rotates, it can drive the second rotation angle detection component 4 to rotate through the transmission component 6; the transmission component 6 includes a first transmission member 60 and a second transmission member 61 that are in transmission connection.
[0089] Furthermore, the first transmission member 60 is fixedly installed on the rotation connection portion 20, and the first rotation angle detection component 3 is integrated on the first transmission member 60 and fixedly connected to the first transmission member 60.
[0090] Furthermore, the second transmission member 61 is located in the connection cavity 10 and is rotatably connected to the pedal base 1. The second rotation angle detection component 4 is integrated on the second transmission member 61 and is in transmission connection with the second transmission member 61; and when the pedal arm 2 rotates relative to the pedal base 1, the first transmission member 60 drives the second transmission member 61 to rotate.
[0091] Specifically, when the pedal assembly for vehicle works, the rotary connection part 20 rotates synchronously with the pedal arm 2. At the same time, the rotary connection part 20 drives the first angle detection component 3 to rotate. Meanwhile, the second angle detection component 4 also rotates synchronously, so as to output the angle signal of the pedal arm 2 and achieve the purpose of detecting the stroke of the pedal arm 2. On the one hand, the reliability of the signal output of the pedal assembly for vehicle is ensured; on the other hand, the transmission connection between the first transmission member 60 and the second transmission member 61 is located in the connection cavity 10 and is protected by the connection cavity 10, improving the reliability of the operation of the pedal assembly for vehicle.
[0092] More specifically, only a transmission part 6 is arranged between the first angle detection component 3 and the second angle detection component 4, and the first angle detection component 3 is integrated on the first transmission member 60, and the second angle detection component 4 is integrated on the second transmission member 61. Just by stepping on the pedal arm 2, the signal output of the first angle detection component 3 and the second angle detection component 4 respectively located on the pedal arm 2 and the pedal base 1 can be realized, and the stroke of the pedal arm 2 can be detected. On the one hand, the structure of the pedal assembly for vehicle is simple, and the safety performance of the vehicle is improved; on the other hand, the size of the pedal assembly for vehicle itself is also reduced.
[0093] The following further describes the specific cooperation relationship between the transmission part 6, the connection cavity 10 and the first angle detection component 3 and the second angle detection component 4.
[0094] As Figures 1 - 4 shown, in the implementation manner disclosed in this embodiment, the rotary connection part 20 is set as: a rotary member 200 located at one end of the pedal arm 2. Both ends of the rotary member 200 are rotatably connected to the inner wall surface of the connection cavity 10, and a bushing 210 is arranged at the rotary connection part of the rotary member 200 and the connection cavity 10.
[0095] A first circular groove 220 is formed on the rotary member 200, and the first circular groove 220 is coaxially arranged with the rotary member 200. One end of the first transmission member 60 extends into the first circular groove 220 and is fixedly connected to the rotary member 200;
[0096] A second circular groove (not shown in the figure) is formed on the inner wall surface of the connection cavity 10. One end of the second transmission member 61 extends into the second circular groove and is rotatably connected to the pedal base 1.
[0097] Specifically, by setting the rotary connection part 20 as the rotary member 200 and arranging the bushing 210 at the rotary connection part of the rotary member 200 and the connection cavity 10; on the one hand, through the rotary connection between the rotary member 200 and the pedal base 1, the response speed is fast when stepping on the pedal arm 2; on the other hand, the friction and wear of the rotary member 200 can be reduced, the strength and wear resistance of the rotary member 200 can be enhanced, and a certain shock absorption function can be provided.
[0098] More specifically, the first circular groove 220 is provided to realize the fixed connection between the first transmission member 60 and the rotating member 200, and the second circular groove is provided to realize the rotational connection between the second transmission member 61 and the pedal base 1; the space occupied by the first transmission member 60 and the second transmission member 61 in the connection cavity 10 can be reduced, so that a relatively small-sized connection cavity 10 can be appropriately designed at the beginning of the design. Therefore, the size of the pedal base 1 will also be reduced, which is convenient for the miniaturization design of the vehicle pedal assembly. When it is applied to a small vehicle, the space occupied by the vehicle is relatively small.
[0099] More specifically, the rotating member 200 can be set as a rotating shaft, a rotating rod, etc., and the present invention does not make specific limitations thereto.
[0100] Further, as Figures 1 - 3 shown, in an embodiment, the first rotation angle detection component 3 includes a first Hall sensor 30 and a first magnetic member 31, and the first transmission member 60 includes a driving gear 600 and a flange 601; wherein, the first magnetic member 31 is mounted on the first Hall sensor 30 and fixedly connected to the first Hall sensor 30, the driving gear 600 is fixedly connected to the first Hall sensor 30, one end of the flange 601 is fixedly connected to the driving gear 600, and the other end extends into the first circular groove 220 and is fixedly connected to the first circular groove 220.
[0101] The second rotation angle detection component 4 includes a second Hall sensor 40 and a second magnetic member 41, and the second transmission member 61 includes a driven gear 610 and a rotating shaft 611; wherein, both the second magnetic member 41 and the driven gear 610 are mounted on the second Hall sensor 40 and fixedly connected to the second Hall sensor 40, one end of the rotating shaft 611 is fixedly connected to the driven gear 610, and the other end extends into the second circular groove and is rotationally connected to the second circular groove; and, the driving gear 600 and the driven gear 610 mesh with each other.
[0102] Specifically, through the meshing of the driving gear 600 and the driven gear 610, when the pedal arm 2 is stepped on, the driving gear 600 drives the driven gear 610 to rotate, so that both the first Hall sensor 30 and the second Hall sensor 40 rotate. At this time, the distance between the Hall sensor and the magnet changes, and the corresponding output voltage value also changes. By measuring the corresponding relationship between this output voltage value and the position of the magnet, the angular displacement data of the pedal arm 2 can be calculated, so as to realize the output of the rotation angle signal of the pedal arm 2 and detect the stroke signal of the pedal arm 2. This signal will be received by the control system, and then a control instruction will be issued to control the throttle to quickly and accurately open the angle it should open according to the instruction. Therefore, the designed Hall sensor can accurately detect the rotation angle signal of the pedal arm 2, and two Hall sensors are set, one is located on the dynamic structural member and the other is located on the static structural member. On the one hand, it ensures the stability of the signal output, and on the other hand, it ensures the redundancy of the signal, realizes the reliability of the pedal work, and improves the safety performance of the vehicle.
[0103] It should be understood that both the first Hall sensor 30 and the second Hall sensor 40 are angular Hall sensors.
[0104] More specifically, both the first magnetic member 31 and the second magnetic member 41 can be set as magnetic blocks, magnetic strips, magnetic sheets, etc., and this embodiment does not make specific limitations here.
[0105] More specifically, in this implementation manner, the transmission ratio of the driving gear 600 to the driven gear 610 is 1:1 to 3. When the transmission ratio of the driving gear 600 to the driven gear 610 is 1:1, the driving gear 600 and the driven gear 610 rotate the same angle, which can ensure that the output rotation angle signals are the same; when the transmission ratio of the driving gear 600 to the driven gear 610 is different, such as 1:1.5 or 1:2 or 1:3, the rotation angle of the driven gear 610 is amplified, and the second Hall sensor 40 can more accurately detect the rotation angle signal, so as to accurately detect the stroke of the pedal arm 2.
[0106] In another implementation manner, the first rotation angle detection component 3 is set as a first angle sensor, and the first transmission component 60 is set as a worm gear; the first angle sensor is installed on the worm gear and fixedly connected to the worm gear, and the worm gear is fixedly connected to the rotating component 200. The second rotation angle detection component 4 is set as a second angle sensor, the second transmission component 61 is set as a worm, the second angle sensor is installed on the worm and fixedly connected to the worm, and both ends of the worm are rotatably connected to the inner wall surface of the connection cavity 10. And, the worm gear meshes with the worm.
[0107] Specifically, through the meshing of the worm gear and the worm, when the pedal arm 2 is stepped on, the worm gear drives the worm to rotate, so that the first angle sensor and the second angle sensor output the angular displacement signal of the pedal arm 2 to detect the stroke of the pedal arm 2.
[0108] Furthermore, the pedal assembly for an automobile provided in this embodiment further includes a force simulation component and a pedal base 7, and the force simulation component and the pedal base 7 will be introduced below.
[0109] As Figures 1 - 4 shown, in the implementation manner disclosed in this embodiment, the pedal base 7 is fixedly installed on one side of the pedal base 1 for installing the pedal assembly for an automobile in the automobile cockpit, thereby realizing the fixed installation of the pedal assembly for an automobile.
[0110] Specifically, a support seat 70 is further provided on the side of the pedal base 7 close to the pedal base 1, and a receiving groove 71 is formed on the support seat 70, and at least part of the rotating member 200 is received in the receiving groove 71. Thus, the receiving groove 71 has a certain supporting effect on the rotating member 200, reducing the risk of damage to the rotating member 200 during frequent use; and, by providing the receiving groove 71, when the pedal base 7 is installed on the pedal base 1, since the receiving groove 71 can receive part of the rotating member 200, therefore, the size of the connecting cavity 10 is reduced, and further the size of the pedal assembly for an automobile is reduced, so that the pedal assembly for an automobile occupies less space in the automobile.
[0111] More specifically, one end of the force simulation component 8 is fixedly connected to the pedal arm 2, and the other end is fixedly connected to the pedal base 7. When the pedal arm 2 is stepped on, it can simulate the pedal feeling, making the driver feel the force lag feeling and increasing the operation comfort.
[0112] Furthermore, in the implementation manner disclosed in this embodiment, the force simulation component 8 includes a first elastic member 80 and a second elastic member 81, and the first elastic member 80 and the second elastic member 81 are arranged at intervals between the pedal arm 2 and the pedal base 7.
[0113] One end of the first elastic member 80 is fixedly connected to the pedal arm 2, and the other end is fixedly connected to the pedal base 7. One end of the second elastic member 81 is fixedly connected to the pedal arm 2, and the other end is fixedly connected to the pedal base 7.
[0114] Specifically, by providing the first elastic member 80 and the second elastic member 81, when the driver steps on the pedal arm 2, it can better simulate the force lag feeling close to human stepping, improving the driving comfort of the driver.
[0115] As Figure 1As shown, in one embodiment, the first elastic member 80 includes a first spring 800, a first limiting member, a second spring 801, and a second limiting member 802. The first limiting member is fixedly installed on the pedal arm 2. One end of the first spring 800 is fixedly connected to the first limiting member, and the other end is fixedly connected to one end of the second spring 801. The second limiting member 802 is fixedly installed on the pedal base 7, and the other end of the second spring 801 is fixedly connected to the second limiting member 802. Moreover, the radial dimension of the first spring 800 is larger than that of the second spring 801.
[0116] Specifically, the radial dimension of the first spring 800 is designed to be larger than that of the second spring 801. By connecting springs of different sizes in series, fine adjustment of force and displacement can be achieved. In addition, this design also takes into account the load capacity of the vehicle, and can adjust the rigidity and load capacity of the spring system, so as to adapt to different usage scenarios and load requirements. For example, this vehicle pedal assembly can be applied to clutch pedals, brake pedals, accelerator pedals, etc.
[0117] Furthermore, the second elastic member 81 includes a third spring 810 and a pair of third limiting members 811. One of the pair of third limiting members 811 is fixedly connected to the pedal arm 2, and the other is fixedly connected to the pedal base 7. One end of the third spring 810 is fixedly connected to one of the third limiting members 811 in the pair of third limiting members 811, and the other end is fixedly connected to the other third limiting member 811 in the pair of third limiting members 811.
[0118] Specifically, by providing the first limiting member, the second limiting member 802, and the third limiting member 811 to limit the springs, it can be ensured that the springs will not deviate when being squeezed or rebounded, thus ensuring the reliability of the operation of this vehicle pedal assembly.
[0119] More specifically, the spring has a resilience force. When the driver releases the pedal arm 2, the spring can cause the pedal arm 2 to automatically return to its original position.
[0120] More specifically, the first limiting member, the second limiting member 802, and the third limiting member 811 can all be set as spring limiting seats, limiting grooves, etc., and this embodiment does not make any limitations here.
[0121] In another embodiment, both the first elastic member 80 and the second elastic member 81 include elastic rubber columns and limiting cavities. One end of the limiting rod cavity is fixedly connected to the pedal base 7, and the other end is fixedly connected to the pedal arm 2. And the limiting cavity includes a first accommodating cavity and a second accommodating cavity, and the first accommodating cavity is slidably connected to the second accommodating cavity. The elastic rubber column is arranged in the limiting cavity, with one end fixedly connected to the pedal base 7 and the other end fixedly connected to the pedal arm 2.
[0122] Specifically, during the process of stepping on the pedal arm 2, the elastic rubber column is compressed, and at the same time, the first accommodation cavity and the second accommodation cavity will slide relative to each other, so as to achieve the purpose of simulating the feeling of pedal force lag.
[0123] Furthermore, as Figure 4 shown, in the implementation manner disclosed in this embodiment, the vehicle pedal assembly can have multiple uses, such as an accelerator pedal, a clutch pedal, a brake pedal, etc. Taking the vehicle pedal assembly as a brake pedal assembly as an example; the other end of the pedal arm 2 extends towards the interior of the vehicle, and a pedal cover 9 is further provided on the other end of the pedal arm 2, and the pedal cover 9 covers the other end of the pedal arm 2.
[0124] Specifically, by setting the pedal cover 9, on the one hand, the stepping area of the driver is increased, and on the other hand, it also has an anti-slip effect, improving the safety of the brake pedal assembly.
[0125] Furthermore, the present utility model also provides a vehicle, including a vehicle pedal assembly, and the vehicle pedal assembly is installed in the driver's cab of the vehicle.
[0126] Specifically, when the vehicle pedal assembly is installed in the driver's cab of the vehicle, since the first corner detection component 3 and the second corner detection component 4 are provided on the vehicle pedal assembly, which are respectively located on the pedal arm 1 and the pedal base 2, two independent pedal arm 2 corner displacement signals are output to monitor the displacement stroke of the pedal arm 2, so as to achieve signal redundancy and improve the safety performance of the vehicle. And when a problem occurs in one of the signals or one of the corner detection components is damaged during maintenance or use, there is still one working properly, ensuring the realization of the function of the vehicle pedal assembly, and thus ensuring the safety of the passengers in the vehicle. And by setting two corner detection components and using electronic signals to transmit the stroke of the pedal arm 2, the response speed of the corresponding pedals on the vehicle is also greatly improved, such as the brake pedal, the accelerator pedal, etc.
