Description

Technical Field

[0001] This application relates to the field of automotive component testing technology, specifically to a pedal assembly and a vehicle. Background Technology

[0002] With the deepening of automotive platform development, different models have significant differences in wheelbase, floor height, front bulkhead position, and ergonomic hard points, resulting in different accelerator pedal travel.

[0003] However, in existing technologies, the limited adjustment dimensions and lack of flexibility of verification devices make it difficult to accurately simulate the real-world operating conditions of multiple vehicle models without replacing the hardware. Therefore, when characteristics such as pedal travel are required during the R&D process, it is often necessary to create new molds or build new dedicated test benches, resulting in lengthy verification cycles and high modification costs. Summary of the Invention

[0004] In view of the above problems, this application provides a pedal assembly and a vehicle, which provides an efficient, low-cost and highly realistic means of real vehicle road testing for vehicle development.

[0005] To achieve the above objectives, this application provides a pedal assembly including a mounting base, a pedal body, a stop portion, and a travel adjustment assembly. The pedal body is rotatably connected to the mounting base and is rotatable relative to the mounting base. The stop portion is connected to the side of the pedal body facing the mounting base and is used to rotate with the pedal body relative to the mounting base to move the stop portion closer to or away from the mounting base. The travel adjustment assembly is connected to the side of the mounting base facing the pedal body and has multiple limiting portions. The travel adjustment assembly is movable relative to the mounting base to move one of the limiting portions to a stop position. The stop portion is used to abut against the limiting portion located at the stop position. Different limiting portions at the stop position restrict the travel of the stop portion closer to the mounting base differently.

[0006] In one alternative embodiment, each of the plurality of limiting portions protrudes at a different height relative to the abutment at the abutment position, so that the different limiting portions at the abutment position limit the travel of the abutment towards the mounting base in different ways.

[0007] In one optional embodiment, a plurality of the limiting portions are arranged sequentially on the mounting base according to the height of each limiting portion protruding relative to the abutment portion at the abutment position, and each limiting portion is arranged circumferentially along the same concentric arc.

[0008] In one optional embodiment, the mounting base is provided with a mounting groove, and each of the limiting parts is located in the mounting groove. The travel distance of the abutment part approaching the mounting base is adjusted by the sequential rotation of the limiting parts along the groove wall of the mounting groove.

[0009] In one optional embodiment, the pedal assembly further includes an elastic element and an adjusting element. One end of the elastic element abuts against the mounting base, and the other end is connected to the adjusting element. The adjusting element is movably connected to the pedal body and can adjust the initial compression of the elastic element between the pedal body and the mounting base. The elastic element undergoes elastic compression when an external force drives the pedal body to rotate closer to the mounting base, and when the external force disappears, the deformation restoring force of the elastic element drives the pedal body away from the mounting base.

[0010] In one optional embodiment, the pedal body is provided with a threaded hole that extends through the pedal body along the extension and retraction direction of the elastic element, and the adjusting member is threadedly connected to the wall of the threaded hole; wherein, as the adjusting member gradually approaches the mounting base along the axial direction of the threaded hole, the initial compression of the elastic element between the pedal body and the mounting base is gradually increased simultaneously; as the adjusting member gradually moves away from the mounting base along the axial direction of the threaded hole, the initial compression of the elastic element between the pedal body and the mounting base is gradually decreased simultaneously, until the initial compression of the elastic element between the pedal body and the mounting base disappears.

[0011] In one optional embodiment, the pedal body includes a connecting portion, a pedal portion, and a first fastener. The connecting portion is hinged to the mounting base and connected to the abutment portion. The pedal portion is hinged to the connecting portion. The first fastener is connected between the pedal portion and the connecting portion and has a tightened state and an unlocked state. When the first fastener is in the unlocked state, the pedal portion can rotate relative to the connecting portion to adjust the angle of the pedal portion relative to the connecting portion. When the first fastener is in the tightened state, the pedal portion can be fixed relative to the connecting portion to maintain the angle of the pedal portion relative to the connecting portion.

[0012] In one optional embodiment, the connecting portion includes a first connecting segment, a second connecting segment, and a second fastener. The first connecting segment is hinged to the mounting base and connected to the abutment portion. The second connecting segment is hinged to the first connecting segment and to the pedal portion. The second fastener is connected between the first connecting segment and the second connecting segment and has a tightened state and an unlocked state. When the second fastener is in the unlocked state, the second connecting segment can move up and down relative to the first connecting segment from the connecting portion toward the pedal portion to adjust the height of the second connecting segment relative to the first connecting segment. When the second fastener is in the tightened state, the second connecting segment can be fixed relative to the first connecting segment to maintain the height of the second connecting segment relative to the first connecting segment.

[0013] In one optional embodiment, the first connecting segment includes a rotating part, a sliding part, and a third fastener. The rotating part is hinged to the mounting base and connected to the abutment part. One end of the sliding part is slidably connected to the rotating part, and the other end is hinged to the second connecting segment. The pedal assembly has a first direction, a second direction, and a third direction that intersect each other. The pedal body rotates along the first direction. The rotating part and the sliding part are sequentially arranged along the second direction. The sliding part reciprocates relative to the rotating part along the third direction. The third fastener has a tightened state and an unlocked state. When the third fastener is in the unlocked state, the sliding part can slide relative to the rotating part to adjust the position of the sliding part relative to the rotating part in the third direction. When the third fastener is in the tightened state, the sliding part can be fixed relative to the rotating part to maintain the position of the sliding part relative to the rotating part in the third direction.

[0014] A second aspect of this application provides a vehicle including a vehicle body and the aforementioned pedal assembly, wherein the mounting bracket is connected to the vehicle body.

[0015] In this application, because the stroke adjustment component can move relative to the mounting base, different limiting parts can be switched to the abutting position. By utilizing the differences in stroke restriction imposed by different limiting parts on the abutting part's approach to the mounting base, the pedal body can have different maximum pedal strokes in different limiting states. This effectively solves the problem of traditional verification devices having fixed strokes and being unable to adapt to the needs of multiple vehicle models. Therefore, it provides an efficient, low-cost, and highly realistic real-vehicle road testing method for vehicle development.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0027] Combination Figures 1 to 8 As shown, this application provides a pedal assembly, which includes a mounting base 10, a pedal body 20, a stop portion 30, and a travel adjustment assembly 40. The pedal body 20 and the mounting base 10 are rotatably connected, and the pedal body 20 is rotatable relative to the mounting base 10. The stop portion 30 is connected to the side of the pedal body 20 facing the mounting base 10, and the stop portion 30 is used to rotate with the pedal body 20 relative to the mounting base 10 so that the stop portion 30 approaches or moves away from the mounting base 10. The travel adjustment assembly 40 is connected to the side of the mounting base 10 facing the pedal body 20, and the travel adjustment assembly 40 is provided with a plurality of limiting portions 41. The travel adjustment assembly 40 is rotatable relative to the mounting base 10 so that one of the limiting portions 41 moves to the stop position, and the stop portion 30 is used to abut against the limiting portion 41 located at the stop position. Different limiting portions 41 restrict the travel of the stop portion 30 approaching the mounting base 10 differently at the stop position.

[0028] It should be understood that the pedal body 20 refers to the main component for the driver's foot to press and transmit operating force. When an external force is applied to the pedal body 20, the pedal body 20 produces angular displacement, simulating the pedal action during vehicle acceleration; when the external force disappears, the pedal body 20 can return to its initial position under the action of the reset mechanism.

[0029] In an exemplary embodiment of this application, the pedal body 20 and the mounting base 10 are rotatably connected by means of a pin hinge, bearing support or elastic bushing connection, so that the pedal body 20 can reciprocate relative to the mounting base 10 about a certain fixed axis.

[0030] In an exemplary embodiment of this application, the abutment 30 may be, for example, a raised stop, an extended rib, or an embedded roller, as long as it can form an effective abutment with the limiting part 41. This embodiment of the application does not impose any special limitations on this.

[0031] It should be understood that when the driver depresses the pedal body 20, the pedal body 20 rotates around its connection point with the mounting base 10, causing the abutment part 30 connected to one side to swing synchronously towards the mounting base 10. Simultaneously, a pre-selected limit part 41 via the stroke adjustment assembly 40 is already in the abutment position. As the rotation angle of the pedal body 20 increases, the distance between the abutment part 30 and the limit part 41 gradually decreases until they rigidly abut against each other. At this point, the limit part 41 applies a reverse supporting force to the abutment part 30, preventing the pedal body 20 from continuing to rotate, thus defining the maximum pedal travel in the current state. If the travel needs to be adjusted, the stroke adjustment assembly 40 is driven to move relative to the mounting base 10, causing another limit part 41 of a different size to enter the abutment position. When the pedal is depressed again, the abutment part 30 will be blocked in the new position, thereby changing the travel length.

[0032] In this application, since the stroke adjustment component 40 can move relative to the mounting base 10, different limiting parts 41 can be switched to the abutment position. By utilizing the differences in stroke restriction of the abutment part 30 towards the mounting base 10 by different limiting parts 41, the pedal body 20 can have different maximum pedal strokes in different limiting states. This effectively solves the problem of fixed stroke in traditional verification devices, which cannot adapt to the needs of multiple vehicle models. Therefore, it provides an efficient, low-cost, and highly realistic real-vehicle road testing method for vehicle development.

[0033] Combination Figure 2 As shown, the height at which each of the multiple limiting parts 41 protrudes relative to the abutting part 30 at the abutting position is different, so that the different limiting parts 41 limit the travel of the abutting part 30 toward the mounting base 10 at the abutting position in different ways.

[0034] It should be understood that the different protrusion heights of each of the multiple limiting parts 41 relative to the abutting part 30 at the abutting position refer to the fact that when the various limiting structures provided on the stroke adjustment assembly 40 are adjusted to the abutting position that cooperates with the abutting part 30, their vertical distances from the abutting part 30 along the movement direction of the abutting part 30 are different, thereby causing the abutting part 30 to travel different distances to any of the limiting parts 41 located at the abutting position. This height difference can be a step-like abrupt height or a continuous height that gradually changes along an arc; this embodiment of the application does not impose any special limitations on this.

[0035] In a preferred embodiment, the travel adjustment component 40 is assumed to be a rotatable disk with multiple limiting parts 41 distributed circumferentially along its edge. The first limiting part 41 protrudes at a height of H1 at the abutment position, and the second limiting part 41 protrudes at a height of H2 at the abutment position, where H1 > H2. When the user rotates the disk to bring the first limiting part 41 to the abutment position, the abutment part 30 contacts the limiting part 41 when the pedal is depressed at a rotation angle of α1, at which point the pedal travel is S1. When the user rotates the disk to bring the second limiting part 41 to the abutment position, the abutment part 30 needs to rotate to an angle of α2 (α2 > α1) before contacting the limiting part 41, at which point the pedal travel is S2 (S2 > S1).

[0036] In this application, since the heights of the multiple limiting parts 41 protruding from the abutting part 30 at the abutting position are different, the higher limiting part 41 can contact the abutting part 30 earlier to terminate the pressing of the pedal body 20 in advance, while the lower limiting part 41 allows the pedal body 20 to press down a longer distance, thereby realizing a reliable and easy-to-manufacture stroke adjustment mechanism.

[0037] Combination Figure 2 As shown, multiple limiting parts 41 are arranged sequentially on the mounting base 10 according to the height of each limiting part 41 protruding relative to the abutting part 30 at the abutting position, and each limiting part 41 is arranged circumferentially along the same concentric arc.

[0038] As a preferred embodiment, assuming the pedal assembly is used for accelerator pedal verification in a certain vehicle model, in the initial state, when the travel adjustment component 40 is in its initial position, the highest limiting part 41 is in the abutment position. When the pedal is pressed, the abutment part 30 can only move a short distance before contacting the limiting part 41, simulating the characteristics of a short-travel pedal. When it is necessary to simulate a long-travel pedal, the user rotates the travel adjustment component 40. The rotation causes the next highest limiting part 41 to smoothly rotate into the abutment position, while the original limiting part 41 disengages from that position. When the pedal is pressed again, the abutment part 30 can move a longer distance, thus increasing the travel. Continuing to rotate the travel adjustment component 40, the lower limiting parts 41 successively enter the working position until the maximum travel setting is reached.

[0039] It should be understood that, except for the limiting part 41 located at the abutment position, the other limiting parts 41 may not be located between the mounting base 10 and the pedal body 20, so as to avoid the other limiting parts 41 interfering with the rotation of the pedal body 20 when it rotates toward the mounting base 10; or, when the pedal body 20 rotates to the closest position to the mounting base 10, that is, when the abutment 30 contacts the limiting part 41 with the smallest protrusion height, the limiting part 41 with the largest protrusion height, the abutment 30, and the pedal body 20 are all spaced apart to ensure that they do not interfere with the rotation of the pedal body 20.

[0040] In this application, since multiple limiting parts 41 are arranged in sequence according to their protrusion height, the stroke adjustment process has a clear gradient change and predictability, and the user can quickly locate the target stroke according to the arrangement order; at the same time, since each limiting part 41 is arranged circumferentially along the same concentric arc, the limiting parts 41 are easy to adjust and the spatial layout of the limiting parts 41 can be optimized.

[0041] Combination Figure 3 As shown, the mounting base 10 is provided with a mounting groove 101, and each limiting part 41 is located in the mounting groove 101. The travel distance of the abutment part 30 approaching the mounting base 10 is adjusted by rotating it sequentially along the groove wall of the mounting groove 101.

[0042] It should be understood that the mounting groove 101 refers to a recessed structure formed on the side of the mounting base 10 facing the pedal body 20. Its shape can be adapted to the outer contour of the entire stroke adjustment assembly 40 to accommodate and guide the movement trajectory of each limiting part 41. Specifically, the mounting groove 101 provides a unified mounting space and movement guide path for multiple limiting parts 41, ensuring that each limiting part 41 can be arranged circumferentially according to a preset concentric arc. The groove wall of the mounting groove 101 restricts the degree of freedom of the limiting parts 41, allowing them to rotate and switch only along the groove wall. This ensures that, under vehicle driving vibration conditions, the unselected limiting part 41 will not undergo accidental displacement, maintaining the stability of the stroke adjustment.

[0043] In a preferred embodiment, assume that the mounting base 10 has an arc-shaped mounting groove 101, and the stroke adjustment component 40 is a disc that can rotate around its center. Five limiting portions 41 of progressively increasing height (labeled H1, H2, H3, H4, and H5) are evenly distributed along the circumferential edge of the disc. Initially, the limiting portion 41 at height H1 is in the abutment position, limiting the pedal's stroke to a larger range. When the driver or tester needs to simulate short-stroke pedal characteristics, the knob on the stroke adjustment component 40 can be turned, causing the disc to rotate within the mounting groove 101 until the limiting portion 41 at height H2 moves along the groove wall to the abutment position, and H1 moves out. When the pedal is pressed again, the abutment portion 30 will contact the higher H2, at which point the pedal body 20 rotates less, thus reducing the stroke distance. To further reduce the stroke, it can be rotated to position H3.

[0044] In this application, a mounting groove 101 is integrated on the mounting base 10 to accommodate and guide the movement of the limiting part 41. By rotating along the groove wall, the limiting parts 41 of different specifications can be quickly switched to the working position. Thus, while ensuring a compact structure and vibration resistance, the pedal stroke can be adjusted in multiple positions or continuously, meeting the precise control requirements of the effective operating range of the pedal under different vehicle models or different test conditions.

[0045] Combination Figure 1 , Figure 4 , Figure 5 and Figure 8 As shown, the pedal assembly also includes an elastic element 50 and an adjusting element 60. One end of the elastic element 50 abuts against the mounting base 10, and the other end is connected to the adjusting element 60. The adjusting element 60 is movably connected to the pedal body 20 and can adjust the initial compression of the elastic element 50 between the pedal body 20 and the mounting base 10. The elastic element 50 undergoes elastic compression when an external force drives the pedal body 20 to rotate closer to the mounting base 10, and when the external force disappears, the deformation restoring force of the elastic element 50 drives the pedal body 20 away from the mounting base 10.

[0046] It should be understood that, in the initial state, the elastic element 50 is in a preset compressed state, providing a basic restoring torque for the pedal body 20. When the driver applies pressure with their foot, the pedal body 20 rotates around the hinge point, causing the adjusting element 60 to move synchronously, further compressing the elastic element 50. At this time, the reaction force generated by the elastic element 50 increases with the increase of compression, forming a force-displacement curve that simulates the throttle characteristics of a real vehicle. During the pedaling process, the deformation of the elastic element 50 directly corresponds to the pedal travel depth, and its stiffness coefficient and the initial compression together determine the force felt by the driver. When the driver releases the external force, the elastic element 50 releases its stored elastic potential energy, pushing the adjusting element 60 to move in the opposite direction, thereby driving the pedal body 20 to rotate back to the initial limit position, completing one complete pedaling cycle. If the force needs to be adjusted, simply operate the adjustment component 60 to adjust the initial compression of the elastic element 50 between the pedal body 20 and the mounting base 10. This allows the initial compression of the elastic element 50 to be reset without disassembling the device, thus achieving precise control of starting force, stroke force, and maximum pedaling force.

[0047] In a preferred embodiment, the pedal body 20 is provided with a threaded hole extending through the elastic member 50 along the extension and retraction direction. The threaded hole extends through the pedal body 20 along the extension and retraction direction of the elastic member 50. The adjusting member 60 is designed as an adjusting bolt or knob with external threads, which is threadedly connected to the wall of the threaded hole. The elastic member 50 is sleeved on the outside or inside of the adjusting member 60, with one end abutting against the bottom surface of the groove of the mounting base 10, and the other end abutting against the stepped surface or nut end face of the adjusting member 60. When it is necessary to increase the pedaling force, rotate the adjusting member 60 clockwise. The adjusting member 60 gradually moves closer to the mounting base 10 along the axial direction of the threaded hole, thereby simultaneously increasing the initial compression of the elastic member 50 between the pedal body 20 and the mounting base 10. When it is necessary to decrease the pedaling force, rotate the adjusting member 60 counterclockwise. The adjusting member 60 gradually moves away from the mounting base 10 along the axial direction of the threaded hole, thereby simultaneously decreasing the initial compression of the elastic member 50 between the pedal body 20 and the mounting base 10 until the initial compression of the elastic member 50 between the pedal body 20 and the mounting base 10 disappears.

[0048] In addition, to prevent the adjustment component 60 from loosening spontaneously due to road test vibration, an anti-loosening washer or thread-locking adhesive can be applied between the adjustment component 60 and the pedal body 20, or a double nut locking structure can be used.

[0049] In this application, the elastic element 50 and the adjustable adjustment element 60 are provided, so that the initial compression of the elastic element 50 can be flexibly adjusted according to actual needs. This solves the problem that the pedal force characteristics are fixed in the prior art and cannot be adapted to the verification needs of multiple vehicle models. It achieves the technical effect of continuous adjustment of the pedal starting force, stroke force and maximum pedal force in the whole range, and significantly improves the realism and flexibility of the verification device in simulating the foot feel of a real vehicle.

[0050] Furthermore, since the adjusting member 60 is connected to the threaded hole on the pedal body 20 by a thread, the adjusting member 60 can move precisely along the axial direction by rotation, thereby continuously and steplessly changing the initial compression of the elastic member 50. At the same time, because the threaded connection has self-locking properties, the adjusted state can be stably maintained, avoiding the drift of the preset pedal force characteristics caused by vibration during vehicle operation. This solves the problem in the prior art that the pedal force characteristics are difficult to be quickly and accurately fine-tuned on the road test site, and achieves the technical effect of flexible, quantitative and stable control of the pedal force characteristics.

[0051] Combination Figure 1 As shown, the pedal body 20 includes a connecting part 21, a pedal part 22, and a first fastener 23. The connecting part 21 is hinged to the mounting base 10 and connected to the abutment part 30. The pedal part 22 is hinged to the connecting part 21. The first fastener 23 is connected between the pedal part 22 and the connecting part 21 and has a tightened state and an unlocked state. When the first fastener 23 is in the unlocked state, the pedal part 22 can rotate relative to the connecting part 21 to adjust the angle of the pedal part 22 relative to the connecting part 21. When the first fastener 23 is in the tightened state, the pedal part 22 can be fixed relative to the connecting part 21 to maintain the angle of the pedal part 22 relative to the connecting part 21.

[0052] It should be understood that the first fastener 23 may refer to a locking mechanism for restricting or releasing relative rotation between the pedal portion 22 and the connecting portion 21.

[0053] For example, the first fastener 23 can be a bolt or nut assembly combined with a butterfly handle, a quick-release handle, an eccentric wheel locking element, or a butterfly knob, etc.

[0054] Preferably, the first fastener 23 includes a bolt, a nut, and a butterfly handle. The butterfly handle is connected to one end of the bolt, and the other end of the bolt passes through the pedal portion 22 and the connecting portion 21. The nut is used to fasten or unlock the pedal portion 22 and the connecting portion 21.

[0055] In this application, since the pedal body 20 is divided into a relatively rotatable connecting part 21 and a pedal part 22, and the angle of the two is adjustable and locked by the first fastener 23, the inclination angle of the pedal body 20 can be flexibly adjusted without changing the overall installation position and stroke characteristics of the pedal assembly. This solves the technical problem that traditional fixed pedals cannot adapt to different driver foot postures, resulting in poor comfort, and achieves the technical effect of improving the adaptability of ergonomic verification and driving comfort.

[0056] Furthermore, combined Figure 4 As shown, the connecting part 21 includes a first connecting segment 211, a second connecting segment 212, and a second fastener 213. The first connecting segment 211 is hinged to the mounting base 10 and connected to the abutment part 30. The second connecting segment 212 is hinged to the first connecting segment 211 and to the pedal part 22. The second fastener 213 is connected between the pedal part 22 and the connecting part 21 and has a tightened state and an unlocked state. When the second fastener 213 is in the unlocked state, the second connecting segment 212 can move up and down relative to the first connecting segment 211 from the connecting part 21 toward the pedal part 22 to adjust the height of the second connecting segment 212 relative to the first connecting segment 211. When the second fastener 213 is in the tightened state, the second connecting segment 212 can be fixed relative to the first connecting segment 211 to maintain the height of the second connecting segment 212 relative to the first connecting segment 211.

[0057] The second fastener 213 can be a bolt and nut assembly with a butterfly handle, or an eccentric wheel cam locking mechanism to achieve quick clamping, or a knob structure with a self-locking function. This application embodiment does not make any special limitations on this.

[0058] Preferably, the second fastener 213 includes a bolt, a nut, and a butterfly handle. The butterfly handle is connected to one end of the bolt, and the other end of the bolt passes through the first connecting segment 211 and the second connecting segment 212. The nut is used to fasten or unlock the first connecting segment 211 and the second connecting segment 212.

[0059] In this application, the introduction of a two-stage adjustment structure consisting of a first connecting section 211, a second connecting section 212, and a second fastener 213 makes the connecting part 21 no longer limited to a single rigid connection or a single-stage rotation, but has an independent degree of freedom for height adjustment; thereby solving the technical problem that the traditional pedal device has a single adjustment dimension and is difficult to adapt to different driver ankle postures and complex human-machine layout requirements.

[0060] Furthermore, combined Figure 6As shown, the first connecting section 211 includes a rotating part 2111, a sliding part 2112, and a third fastener 2113. The rotating part 2111 is hinged to the mounting base 10 and connected to the abutment part 30. One end of the sliding part 2112 is slidably connected to the rotating part 2111, and the other end is hinged to the second connecting section 212. The pedal assembly has a first direction, a second direction, and a third direction that intersect each other. The pedal body 20 rotates along the first direction, and the rotating part 2111 and the sliding part 2112 are arranged sequentially along the second direction. The third fastener 2113 reciprocates along the third direction relative to the rotating part 2111; the third fastener 2113 has a tightened state and an unlocked state; wherein, when the third fastener 2113 is in the unlocked state, the sliding part 2112 can slide relative to the rotating part 2111 to adjust the position of the sliding part 2112 relative to the rotating part 2111 in the third direction; when the third fastener 2113 is in the tightened state, the sliding part 2112 can be fixed relative to the rotating part 2111 to maintain the position of the sliding part 2112 relative to the rotating part 2111 in the third direction.

[0061] In an exemplary embodiment of this application, the rotating part 2111 and the mounting base 10 can be rotatably connected by a pin, bearing or ball joint, thereby allowing the pedal body 20 to perform the rotational movement required for pedaling in the first direction. At the same time, the rotating part 2111 also undertakes the task of connecting with the abutment part 30, ensuring that the abutment part 30 can rotate synchronously with the pedal body 20.

[0062] For example, the third fastener 2113 can be a bolt and nut pair, a wing screw, an eccentric wheel locking mechanism, a wedge locking mechanism, or a quick clamp, etc. For instance, a set screw that passes through the side wall of the rotating part 2111 and presses against the surface of the sliding part 2112 can be used, or a bolt that passes through the overlapping part of both and generates axial clamping force by tightening can be used. Those skilled in the art can select a suitable type of fastener according to the actual required locking force and ease of operation, and the embodiments of this application do not make special limitations in this regard.

[0063] In this embodiment, the first direction generally corresponds to the direction of the rotation axis of the pedal body 20 when it is pedaled. The second direction may be the direction in which the rotating part 2111 and the sliding part 2112 extend, for example, the length direction of the pedal body 20. The third direction is the direction in which the sliding part 2112 actually slides, and this direction is perpendicular to both the first and second directions, for example, the width direction of the pedal body 20 (i.e., the wheelbase direction of the vehicle after the pedal assembly is installed on the vehicle body).

[0064] In a preferred embodiment, the rotating part 2111 is provided with a guide groove 201, and the sliding part 2112 is provided with a slider embedded in the guide groove 201. The third fastener 2113 is a threaded rod with a handle, which passes through the side wall of the rotating part 2111 and abuts against the side of the sliding part 2112. When it is necessary to raise the pedal, rotate the handle of the third fastener 2113 counterclockwise to release the pressure on the sliding part 2112, push the sliding part 2112 in a third direction, observe the scale on the rotating part 2111 or the sliding part 2112, when the scale indicates the target height value, rotate the handle of the third fastener 2113 clockwise until the threaded rod tightly abuts against the sliding part 2112, and the locking is completed. Subsequently, the driver can conduct a road test. If the pedal height is uncomfortable, the above steps can be repeated after parking for fine adjustment without disassembling any parts.

[0065] In this application, the pedal body 20 rotates along a first direction, and the rotating part 2111 and the sliding part 2112 are arranged sequentially along a second direction. The sliding part 2112 slides back and forth relative to the rotating part 2111 along a third direction. Therefore, the pedal body 20 can achieve multi-directional adjustment to adapt to the foot posture of different people.

[0066] This embodiment also provides a vehicle, including a vehicle body and a pedal assembly, with a mounting base 10 connected to the vehicle body.

[0067] The vehicle body can refer to the structural assembly that constitutes the basic framework and shell of a vehicle, and its specific form can be set according to the actual application scenario. For example, the vehicle body can be a test vehicle body-in-white used in the research and development verification stage, an engineering prototype vehicle that has already been equipped with part of the chassis system, or a test carrier specifically used for bench simulation but with actual vehicle mounting interfaces. The vehicle body is equipped with a connection interface for mounting the pedal assembly. This connection interface can be a pre-set mounting hole located on the front bulkhead sheet metal, or a reinforcing bracket in the chassis longitudinal beam or firewall area. The main function of the vehicle body is to provide a stable mounting reference for the pedal assembly, ensuring that the mounting base of the pedal assembly does not undergo relative displacement or deformation during vehicle operation, especially when subjected to dynamic loads generated by road impacts, rapid acceleration, or emergency braking, thereby ensuring the accuracy and repeatability of verification data.

[0068] As a preferred embodiment, in the early stages of developing a new car, the engineering team needs to verify the impact of three different leverage ratios and two different pedal force characteristics on driving comfort. Traditionally, this would require creating five different prototypes and repeatedly disassembling and reassembling them. Using the vehicle described in this application, engineers fixed the adjustable pedal assembly provided in this application to a designated position on the front bulkhead of the vehicle using mounting bracket 10 bolts. First, the travel limit component of the pedal assembly was adjusted, with the limit part 41 adjusted to the first position to simulate the short-travel characteristic of scheme A, and the spring preload was increased by screwing in the adjusting part 60 to simulate the heavy pedal feel of scheme A. The driver drove the vehicle at a test track to conduct acceleration and cruise tests, recording subjective evaluations and objective data. Subsequently, with the vehicle stopped, the engineer, without disassembling any parts, simply loosened the locking knob, rotated the travel adjustment component 40 to the second position, and reversed the adjusting part 60 to reduce the spring pressure. Within ten minutes, this switched to the long-travel, light-feel mode of scheme B, and then the vehicle was tested on the road again. Throughout the process, the vehicle body served as a stable load-bearing platform, ensuring the reliability of comparative data between different solutions and significantly shortening the development cycle.

[0069] In summary, this application achieves the direct embedding of multi-dimensional adjustable pedal verification functionality into a real vehicle system. Because the pedal assembly is detachably connected to the vehicle body via the mounting bracket 10 and possesses continuously adjustable travel, force, and spatial posture, the vehicle can dynamically simulate the pedal handling characteristics of various models without altering its body structure. This approach solves the technical problems of high cost, long cycle time, and poor flexibility caused by traditional road testing relying on fixed prototypes, thereby achieving the technical effects of efficiently acquiring ergonomic data under real dynamic conditions, supporting rapid iterative optimization, and reducing the overall vehicle development risk.
