Description

pedal module and vehicle Technical Field

[0001] This utility model relates to the field of vehicle manufacturing technology, specifically to a pedal module and a vehicle. Background Technology

[0002] With the continuous advancement of automotive technology, autonomous driving has become a key development direction for the automotive industry. In autonomous driving mode, vehicles can autonomously perform operations such as acceleration, deceleration, and steering, which gradually weakens the function of traditional driving control components. Therefore, the hidden functions of the accelerator and brake pedals become extremely important.

[0003] Traditional accelerator and brake pedals are mostly fixed in structure and their positions are not adjustable, resulting in bulky size and high space occupation. Accelerator pedals typically consist of pedal arms, pedal bases, return spring assemblies, and sensors, while brake pedals include the pedal body, connecting mechanisms (such as push rods or hydraulic lines), and assist devices (such as vacuum boosters or electronic power steering systems). These components need to be fixedly installed in the cockpit and cannot be flexibly adjusted or hidden.

[0004] The fixed structure of traditional pedals limits their applicability in autonomous driving mode and fails to meet the demands of modern automobiles for space optimization and lightweight design. Furthermore, this structure occupies a significant portion of the driver's foot space, impacting driver comfort and space utilization.

[0085] The present invention will now be described in detail with reference to various embodiments, examples of which are presented in the accompanying drawings and described below. Although the present invention will be described in conjunction with exemplary embodiments, it should be understood that this specification is not intended to limit the present invention to these exemplary embodiments. Rather, the present invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments that may be included within the spirit of the present invention and the scope defined by the appended claims.

[0086] For ease of interpretation and precise definition of the appended claims, the terms “upper,” “lower,” “front,” “rear,” “left,” “right,” “top,” and “bottom” are used with reference to the positions of these features shown in the accompanying drawings to describe features of the exemplary embodiments.

[0087] The pedal module 10 provided by this utility model can be used as an accelerator pedal module or a brake pedal module for a vehicle. The structure of the pedal module 10 is described below with reference to Figures 1 to 8.

[0088] Referring to Figures 1 and 1a, the pedal module 10 according to this invention is used to output an electrical signal value that can change the vehicle speed. Depending on actual needs, the pedal module 10 can be configured as an accelerator pedal module and a brake pedal module. When the pedal module 10 is used as an accelerator pedal module, it can output an acceleration electrical signal value; when the pedal module 10 is used as a brake pedal module, it can output a braking electrical signal value.

[0089] Referring to Figure 1, the pedal module 10 includes a pedal 100, a housing 200, a circuit board 710, and a pressure sensor 720.

[0090] Referring to Figures 2 and 3, the pedal 100 is rotatably connected to the housing 200 and has an initial position relative to the housing 200. The driver can change the vehicle speed by rotating the pedal 100 relative to the housing 200. Referring to Figures 1a and 3, when the pedal 100 is in the initial position, the pedal module 10 does not output an electrical signal (acceleration signal or braking signal) that can change the vehicle speed. Referring to Figure 3a, when the pedal 100 is rotated downwards and disengaged from the initial position, the pedal module 10 outputs an electrical signal value that can change the vehicle speed, thereby changing the vehicle's speed. Furthermore, the greater the downward angle of the pedal 100 relative to the initial position, the greater the resulting acceleration or braking signal value.

[0091] The connection between the pedal 100 and the housing 200 is illustrated below with reference to the accompanying drawings.

[0092] Referring to Figures 1, 3, and 4, the housing 200 includes a bottom wall 220 and a peripheral wall 210. The peripheral wall 210 surrounds the bottom wall 220, thereby defining an accommodating space. The top of the housing 200 has an opening that connects to the accommodating space. Shaft mounting holes 211 are provided on the left and right sides of the peripheral wall 210 of the housing 200. The bottom surface of the pedal 100 has a connecting portion 110, and the lower end of the connecting portion 110 has a shaft mounting hole 111. The connecting portion 110 of the pedal 100 can extend into the accommodating space through the opening so that the shaft mounting hole 111 aligns with the shaft mounting hole 211.

[0093] The pedal module 10 further includes a shaft 300, and the housing 200 and pedal 100 are rotatably connected via the shaft 300. When assembling the pedal 100 and the housing 200, the shaft mounting hole 211 is aligned with the shaft mounting hole 111, and then the shaft 300 is passed through the shaft mounting holes 211 and 111 so that the pedal 100 can be rotatably connected to the housing 200.

[0094] In some exemplary embodiments, two connecting portions 110 are provided, arranged side by side along the left-right direction, and there is a gap between the two connecting portions 110. Each of the two connecting portions 110 is provided with a shaft mounting hole 111, the two shaft mounting holes 111 are coaxially arranged, and the axis extends along the left-right direction.

[0095] Referring to Figures 2 and 4, a shaft support portion 230 is also provided within the accommodating space of the housing 200, and the shaft support portion 230 is disposed on the bottom wall 220. The shaft support portion 230 is provided with a shaft mounting hole 231, through which the shaft 300 can pass; that is, the shaft mounting hole 231 is coaxially aligned with the shaft mounting hole 211. After the pedal 100 and the housing 200 are assembled, the shaft 300 passes through the two shaft mounting holes 211, the two shaft mounting holes 111, and the shaft mounting hole 231, while the shaft support portion 230 is located between the two connecting portions 110.

[0096] Referring to Figures 1 and 4, a return spring 510 is provided between the pedal 100 and the housing 200. After the driver presses the pedal 100, the return spring 510 can return the pedal 100 to its initial position.

[0097] Referring to Figure 2, a first retaining part 120 for a return spring is provided on the bottom surface of the pedal 100, and the first retaining part 120 for the return spring has a hole 121. A second retaining part 240 for a return spring is provided on the bottom wall 220 of the housing 200, and the second retaining part 240 for the return spring has a hole 241. After the pedal 100 is rotatably connected to the housing 200, the first retaining part 120 for the return spring and the second retaining part 240 for the return spring correspond to each other in the vertical direction. The upper end of the return spring 510 is located in the hole 121, and the lower end of the return spring 510 is located in the hole 241.

[0098] After the driver presses the pedal 100, the return spring 510 is compressed. When the driver withdraws the force from pressing the pedal 100, the return spring 510 gradually returns to its original state, causing the pedal 100 to rotate upward and return to its initial position.

[0099] Referring to Figures 1, 3, and 4, the pedal module 10 further includes a friction block 400, which is disposed in the receiving cavity and located on the lower side of the connecting portion 110.

[0100] Referring to Figure 4a, the lower end of the connecting part 110 is provided with an arc-shaped friction surface 112, and the upper surface of the friction block 400 is provided with an arc-shaped friction surface 410. The arc-shaped friction surface 112 can fit into the arc-shaped friction surface 410.

[0101] In this design, the arc-shaped friction surface 112 is a convex surface, and the arc-shaped friction surface 410 is a concave surface, with the convex surface contained within the concave surface. During the rotation of the pedal 100 relative to the housing 200, the connecting portion 110 rotates relative to the friction block 400, while the arc-shaped friction surfaces 112 and 410 slide against each other, thereby generating friction. It is worth noting that during the rotation of the connecting portion 110 relative to the friction block 400, the convex and concave surfaces remain in contact.

[0102] When the driver depresses pedal 100, the force exerted not only on the return spring 510 (and possibly the pressure spring 520 mentioned later) but also on the friction between the arc-shaped friction surface 112 and the arc-shaped friction surface 410 is required. At this time, the force N1 exerted by pedal 100 on the driver's foot includes the sum of the return spring 510's elastic force and the frictional force (and possibly the added elastic force of the pressure spring 520 mentioned later). During the process of the return spring 510 causing pedal 100 to return to its initial position, the elastic force of the return spring 510 (or possibly the return spring 510 plus the elastic force of the pressure spring 520) overcomes the frictional force. At this time, the force N2 exerted by pedal 100 on the driver's foot is the return spring 510's elastic force (or possibly the return spring 510 plus the elastic force of the pressure spring 520) minus the frictional force. It is understandable that N1 is greater than N2, meaning that the force felt by the driver's foot during the depressing of pedal 100 is greater, which helps the driver distinguish between the upward and downward rotation of pedal 100.

[0103] Referring to Figures 1 and 4, two friction blocks 400 can be provided. The two friction blocks 400 are respectively provided on the left and right sides of the shaft support 230, so as to correspond to the connecting parts 110 on both sides of the shaft support 230.

[0104] Referring to Figures 3 and 4, the shaft support portion 230 is provided with a groove 232, and the peripheral wall 210 of the housing 200 is provided with a hole 212. The two ends of the friction block 400 are respectively held in the groove 232 and the hole 212. Furthermore, grooves 232 are provided on both the left and right sides of the shaft support portion 230, and the peripheral wall 210 of the housing 200 is provided with two holes 212 corresponding to the two grooves 232 to hold the two friction blocks 400.

[0105] Referring to Figures 1, 2, and 5, a circuit board 710 and a pressure sensor 720 are installed in the accommodating space.

[0106] Referring to Figures 5a and 5b, a mounting groove 260 is provided on the bottom wall 220 of the housing 200, and the circuit board 710 is disposed within the mounting groove 260. The mounting groove 260 has continuous sidewalls 261, and the thickness of the circuit board 710 is not greater than the depth of the mounting groove 260. A wiring port 221 is provided at the bottom of the mounting groove 260, through which a wiring harness for signal transmission can connect the circuit board 710 and the vehicle's control system. A pressure sensor 720 is disposed on the circuit board 710 and electrically connected to the circuit board 710.

[0107] Referring to Figures 2 and 5, a pressure spring 520 is disposed between the pedal 100 and the pressure sensor 720, and the pedal 100 applies pressure to the pressure sensor 720 via the pressure spring 520. The pressure applied by the pressure spring 520 to the pressure sensor 720 changes with the rotation angle of the pedal 100 relative to the housing 200. Specifically, when the pedal 100 rotates downward away from its initial position, the pressure spring 520 is compressed, thereby applying pressure to the pressure sensor 720. The greater the downward rotation angle of the pedal 100, the greater the deformation of the compression spring 520, and the greater the pressure applied by the pressure spring 520 to the pressure sensor 720.

[0108] The pressure sensor 720 generates a corresponding pressure sensor electrical signal value based on the pressure applied by the pressure spring 520. This pressure sensor electrical signal value is converted into an acceleration electrical signal value or a braking electrical signal value by the processor on the circuit board 710. The greater the pressure applied by the pressure spring 520 to the pressure sensor 720, the greater the pressure sensor electrical signal value generated by the pressure sensor 720, and the greater the generated acceleration or braking electrical signal value.

[0109] The pedal module 10 further includes a support member 600, which abuts against a pressure sensor 720, and a pressure spring 520 abuts against the support member 600. The pressure generated by the pressure spring 520 is transmitted to the pressure sensor 720 through the support member 600.

[0110] A pressure spring retainer 130 is provided on the bottom surface of the pedal 100. The pressure spring retainer 130 has a hole 131, and the support member 600 has a hole 610. After the pedal 100 is rotatably connected to the housing 200, the pressure spring retainer 130 and the pressure sensor 720 correspond to each other in the vertical direction. The support member 600 is disposed above the pressure sensor 720, and the holes 131 and 610 correspond to each other in the vertical direction. The two ends of the pressure spring 520 are located at holes 131 and 610, respectively.

[0111] Referring to Figures 5, 6, and 7, a resilient contact 630 is provided at the bottom of the support member 600. The resilient contact 630 can be made of rubber. The support member 600 contacts the pressure sensor 720 through the resilient contact 630.

[0112] To ensure the reliability of the sensor signals, two pressure sensors 720 are installed on the circuit board 710, each generating a separate pressure sensor electrical signal value. These two pressure sensor electrical signal values ​​can be cross-referenced when converting between acceleration and braking electrical signal values ​​to improve conversion accuracy. For example, the pressure sensor electrical signal value generated by the pressure sensor 720 and the pressure applied by the pressure spring 520 have a linear relationship; when both pressure sensor electrical signal values ​​show a linear change, the average of the two pressure sensor electrical signal values ​​is used; when only one pressure sensor electrical signal value shows a linear change, that pressure sensor signal value is used; when neither pressure sensor electrical signal value shows a linear change, a warning signal is issued.

[0113] The bottom of the support member 600 is provided with two elastic contacts 630 corresponding to the two pressure sensors 720, and each of the two elastic contacts 630 corresponds to one pressure sensor 720.

[0114] Referring to Figures 5, 5a, and 5b, the housing 200 has a support member holding portion 250 located within the receiving space and positioned on the left and right sides of the mounting groove 260 corresponding to the pressure sensor 720 in the left-right direction. Each support member holding portion 250 has a holding groove 251, and holding arms 620 are formed on the left and right sides of the support member 600, respectively, with the two holding arms 620 respectively held within the two holding grooves 251. The holding grooves 251 extend along the direction in which the support member 600 applies positive pressure to the pressure sensor 720, i.e., the vertical direction shown in the figures. Thus, the support member 600 is limited to movement in the vertical direction.

[0115] As shown in Figures 1, 5, and 6, the pedal module 10 further includes a circuit board cover 800, which is positioned above the mounting groove 260 to cover the circuit board 710 above the mounting groove 260. The circuit board cover 800 is designed to cooperate with the mounting groove 260 to protect the circuit board 710 from dust and water intrusion.

[0116] Referring to Figure 6a, the left and right edges of the circuit board cover 800 form limiting grooves 810, which correspond to and are engaged with the retaining groove 251.

[0117] Two through holes 820 are formed on the circuit board cover 800, and the two through holes 820 correspond to two pressure sensors 720 respectively, so that the circuit board cover 800 can cover the circuit board 710 while exposing the two pressure sensors 720. Two elastic contacts 630 respectively contact their respective pressure sensors 720 through the two through holes 820.

[0118] The circuit board cover 800 also has four corner supports 830, which are supported on the bottom wall 220 of the housing 200 so that the circuit board cover 800 can be placed over the mounting groove 260.

[0119] The pedal 100 is further provided with a limiting arm 140, and a limiting pin 141 is provided at the lower end of the limiting arm 140. The lower end of the limiting arm 140 is provided with a pin hole, and the limiting pin 141 is installed in the pin hole.

[0120] Referring to Figures 3 and 3a, limiting guide rails 270 are formed on the left and right sides of the peripheral wall 210 of the housing 200, and the limiting pin 141 extends into the limiting guide rail 270. During the rotation of the pedal 100 relative to the housing 200, the limiting pin 141 moves within the limiting guide rail 270. The upper end of the limiting guide rail 270 is closed, and the limiting pin 141 can abut against the upper end of the limiting guide rail 270. When the limiting pin 141 abuts against the upper end of the limiting guide rail 270, the pedal 100 is at its extreme upward rotation position, which is the initial position of the pedal 100. The lower end of the limiting guide rail 270 is also closed. In one case, when the pedal 100 rotates downward to its extreme position, the limiting pin 141 can abut against the lower end of the limiting guide rail. At this time, the lower end of the limiting guide rail 270 defines the extreme downward rotation position of the pedal 100. In another scenario, when the pedal 100 is rotated downwards to its limit position, the bottom surface of the pedal 100 and the housing 200 abut against each other, while the limiting pin 141 does not abut against the lower end of the limiting guide rail 270. In this case, the limit position of the pedal 100's downward rotation is not limited by the lower end of the limiting guide rail 270.

[0121] Referring to Figures 1, 3, and 4, the pedal module 10 also includes an upper cover 900, which covers the opening of the housing 200.

[0122] Referring to Figure 8, the top cover 900 has openings 910 and 920. The connecting part 110 of the pedal 100 is connected to the housing 200 via opening 910, and the return spring 510 passes through opening 920.

[0123] This utility model also provides a vehicle in which the pedal module provided by this utility model is used as an accelerator pedal module and / or a brake pedal module.

[0124] By adopting the pedal module of this utility model, it is only necessary to connect the housing of the pedal module to the floor inside the vehicle. This allows for flexible adjustment of the pedal position; when it is necessary to hide the pedal module, only the housing needs to be moved. By setting a corresponding adjustment mechanism, the pedal module 10 can be hidden under the floor inside the vehicle, thereby increasing the space in the driver's seat and improving driver comfort.

[0125] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and descriptive purposes. It is not intended to be exhaustive, nor to limit the invention to the precise forms disclosed; obviously, many changes and variations are possible in accordance with the foregoing teachings. The exemplary embodiments were chosen and described to explain the specific principles of the invention and its practical application, thereby enabling others skilled in the art to implement and utilize various exemplary embodiments of the invention, as well as their different alternatives and modifications. The scope of the invention is defined by the appended claims and their equivalents.
