Description

Technical Field

[0001] This disclosure relates to the field of automotive testing equipment technology, and more specifically, to an accelerator pedal control device. Background Technology

[0002] When conducting vehicle performance tests on a vehicle environmental chamber / chassis dynamometer, it is sometimes necessary to control the opening of the accelerator pedal to obtain vehicle data under specific operating conditions. In related technologies, how to conveniently and accurately control the accelerator pedal is a technical problem that needs to be solved. Utility Model Content

[0003] The purpose of this disclosure is to provide an accelerator pedal control device that can conveniently and accurately adjust the opening of the accelerator pedal.

[0004] To achieve the above objectives, this disclosure provides an accelerator pedal control device, comprising:

[0005] support;

[0006] A drive element, connected to the bracket and adjustable in position and / or angle relative to the bracket; and

[0007] A pushrod assembly is provided for connection to the accelerator pedal. A drive member is induced to connect to the pushrod assembly to change or maintain the accelerator pedal opening. The pushrod assembly includes a telescopic structure for changing its length. This design facilitates adjustment of the accelerator pedal opening.

[0008] Optionally, the telescopic structure includes a first telescopic structure, which comprises a first sleeve and a first rod structure, wherein the first sleeve is lockably slidably connected to the first rod structure. This configuration allows the first telescopic structure to extend rapidly, thereby enabling the push rod assembly to be quickly positioned and connected to the accelerator pedal.

[0009] Optionally, the first telescopic structure includes a first locking member connected to the sleeve for detachably locking the first sleeve to the first rod structure. This configuration simplifies operation, requiring only adjustment of the first locking member to lock and unlock the first sleeve and the first rod structure.

[0010] Optionally, the telescopic structure further includes a second telescopic structure, which comprises the first rod structure and a second sleeve, with the second sleeve threadedly connected to the first rod structure. With this configuration, the relative position between the first rod structure and the second sleeve can be changed by rotating the second sleeve, causing the first rod structure to extend or retract along the extension direction of the push rod assembly. This allows for changing the length of the push rod assembly and can be used to more precisely adjust the pedal opening.

[0011] Optionally, the second telescopic structure further includes a second rod structure. One end of the second sleeve is connected to the first rod structure via a first internal thread, and the other end of the second sleeve is connected to the second rod structure via a second internal thread. The first and second internal threads have opposite directions of rotation. This configuration ensures the adjustment accuracy of the second telescopic structure while allowing for greater length variation with each adjustment, thereby improving adjustment efficiency.

[0012] Optionally, the accelerator pedal control device further includes a clamping member for clamping the accelerator pedal. The clamping member is connected to the push rod assembly, which enables a stable connection between the accelerator pedal control device and the accelerator pedal, ensuring the stability of the connection between the two when the accelerator pedal control device controls the opening degree of the accelerator pedal.

[0013] Optionally, a first universal joint is provided between the push rod assembly and the clamping member. This arrangement allows the mounting angle of the clamping member when holding the accelerator pedal to be changed to accommodate different accelerator pedals; and / or,

[0014] A second universal joint is provided between the push rod assembly and the driving member. This arrangement allows the push rod assembly to rotate relative to the driving member, thus accommodating the angular deviation between the driving member and the push rod assembly caused by movement.

[0015] Optionally, the clamping member includes a base plate, a clamping plate, and a clamping structure. The clamping structure is movably connected to the base plate to move toward or away from the clamping plate to clamp the accelerator pedal together with the clamping plate, thereby achieving stable clamping between the clamping member and the accelerator pedal.

[0016] Optionally, the clamping structure includes a third rod structure connected to the push rod assembly. An adjusting member is rotatably connected to the base plate, and the adjusting member is threadedly connected to the third rod structure to drive the third rod structure to move toward or away from the clamping plate. This configuration allows for fine-tuning of the movement of the third rod structure by adjusting its movement through the threaded connection between the adjusting member and the third rod structure.

[0017] Optionally, the clamp includes at least two plates connected to the base plate, with a gap between the at least two plates. Each plate includes a first plate portion opposite to the base plate and a second plate portion connected between the first plate portion and the base plate, which can avoid obstructing accessories connected to the accelerator pedal in the vehicle and makes it easier for the clamping member to clamp the accelerator pedal.

[0018] Optionally, the drive includes a linear driver connected to the bracket, the output of which is connected to the push rod assembly to drive the push rod assembly to move.

[0019] Optionally, the bracket includes a first frame and a first slide movably connected to the first frame along the height direction. The drive member is rotatably connected to the first slide, and the rotation axis of the drive member is perpendicular to the height direction, so that the drive member can move with the first slide and thereby adjust the height of the drive member.

[0020] Optionally, the bracket includes a second locking member that can be unlockably locked to the drive member on the first slide and / or the first frame, so that the drive member can be unlockably fixed to the first slide and / or the first frame.

[0021] Optionally, the bracket includes a second frame detachably and movably connected to the first frame to adjust its height and / or angle relative to the first frame. The second frame is used to abut and / or connect to the vehicle's seat assembly. This arrangement allows the second frame to support the first frame, preventing the accelerator pedal control device from tipping away from the accelerator pedal when adjusting it.

[0022] Optionally, the bracket includes a third locking member and a second slide movably connected to the first frame in the height direction. The second frame has a mounting hole, and the third locking member passes through the mounting hole and is connected to the second slide. The third locking member can unlockably lock the second frame to the second slide and / or the first frame. This configuration allows the second frame to move relative to the first frame in the height direction with the first slide, and the second frame to rotate relative to the first frame.

[0023] Optionally, the mounting hole is a strip-shaped hole, through which the second frame can move relative to the third locking member. When the distance between the first frame and the seat assembly is different, the movement of the second frame relative to the third locking member can be adjusted so that the second frame abuts against and / or connects to the vehicle's seat assembly; and / or,

[0024] The second frame is rotatable around the third locking member with its rotation axis perpendicular to the height direction. This configuration ensures that the second frame can abut against or connect to the vehicle's seat assembly regardless of the third locking member's position or height.

[0025] Optionally, the bracket further includes a third frame connected to the second frame, and the third frame is provided with a connector for connecting the track of the seat assembly. This arrangement makes the connection between the second frame and the seat assembly more secure.

[0026] Optionally, the connector includes an actuator and a deformable component. The actuator is used to drive the deformable component to deform and abut against the track, thereby achieving a stable connection between the third frame and the track.

[0027] Optionally, the actuator is movably connected to the third frame, and the actuator is located between the pair of deformable elements. Two inclined surfaces of the actuator that abut against the two deformable elements extend towards or away from each other along the direction of movement of the actuator. With this configuration, when the connector connects to the track, the actuator and the deformable elements can be simultaneously inserted into the groove of the track, and then the actuator moves towards the third support. The deformable elements on both sides of the third support can deform and abut against the sidewalls of the groove in the track, thereby fixing the connector in the groove of the track.

[0028] Optionally, the third frame is adjustablely connected to the second frame. This configuration ensures a stable connection between the second and third frames regardless of the accelerator pedal control device's position within the vehicle.

[0029] According to the above technical solution, the accelerator pedal control device includes a bracket, a drive member, and a push rod assembly. The drive member is connected to the bracket and can be adjusted in position and / or angle relative to the bracket. It can quickly adjust the position and / or angle of the drive member relative to the accelerator pedal so that the push rod assembly can be connected to the accelerator pedal and facilitate adjustment of the accelerator pedal opening. In addition, the drive member is driven to the push rod assembly to change or maintain the accelerator pedal opening through the push rod assembly, and the accelerator pedal opening can be quickly adjusted through the drive member. Furthermore, the push rod assembly includes a telescopic structure for changing the length of the push rod assembly. This telescopic structure can be used, for example, to fine-tune the accelerator pedal opening, and / or to quickly extend the push rod assembly to connect with the accelerator pedal or quickly shorten it to retract the accelerator pedal control device.

[0030] In summary, the technical solution provided in this disclosure enables convenient assembly of the accelerator pedal control device and the accelerator pedal and / or fine adjustment of the accelerator pedal opening.

Detailed Implementation

[0045] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0046] In this disclosure, an X-direction is defined for the accelerator pedal control device, which is the height direction of the accelerator pedal control device. The direction pointed to by the X-direction arrow is upward, and vice versa. Unless otherwise stated, directional terms such as "inner" and "outer" refer to the inner and outer contours of the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not have sequential or importance implications. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element.

[0047] This disclosure provides an accelerator pedal control device, such as Figures 1 to 10 As shown, the device includes a bracket 10, a drive member 20, and a push rod assembly 30. The drive member 20 is connected to the bracket 10 and can be adjusted in position and / or angle relative to the bracket 10. The push rod assembly 30 is connected to the accelerator pedal. The drive member 20 drives the push rod assembly 30 to change or maintain the opening of the accelerator pedal. The push rod assembly 30 includes a telescopic structure 300 for changing the length of the push rod assembly 30.

[0048] In the above embodiment, the drive member 20 is driven to connect to the push rod assembly 30. The drive member 20 drives the push rod assembly 30 to change or maintain the opening of the accelerator pedal, which facilitates quick adjustment of the opening of the accelerator pedal.

[0049] Furthermore, the drive component 20 is connected to the bracket 10 and can be adjusted in position and / or angle relative to the bracket 10. It is suitable for multi-directional adjustment and can be adaptively adjusted according to the position of the accelerator pedal in its space or the angle between the accelerator pedal and the vehicle floor, allowing for rapid adjustment of the position and / or angle of the drive component 20 relative to the accelerator pedal. For example, when the vehicle is a sedan or SUV, the required position and / or angle of the drive component 20 relative to the bracket 10 may be different, requiring adaptive adjustment.

[0050] It should be understood that the aforementioned adjustable angle of the drive member 20 relative to the bracket 10 refers to the drive member 20 being angularly connected to the bracket 10. This angular adjustment includes various scenarios. For example, the drive member 20 may be rotatably connected to the bracket 10, with its rotation axis perpendicular to the height direction of the bracket 10. For instance, the drive member 20 may swing up and down around its rotation axis, meaning its pitch angle or swing angle is adjustable. For example, the angle between the linear output direction of the drive member 20 and the horizontal direction can be adjusted. Alternatively, the rotation axis of the drive member 20 may be parallel to or inclined to the height direction of the bracket 10, allowing the drive member 20 to rotate around this rotation axis, thus achieving angle adjustment.

[0051] Furthermore, the drive member 20 can be adjusted in position relative to the bracket 10, for example, in the height direction or in the horizontal direction. This disclosure exemplarily shows that the position of the drive member 20 relative to the bracket 10 in the height direction and the pitch angle can be adjusted, thereby facilitating convenient adjustment of the drive member 20 according to the corresponding vehicle model.

[0052] In addition, the aforementioned push rod assembly 30 includes a telescopic structure 300, which is used to change the length of the push rod assembly 30. This telescopic structure 300 can be used, for example, to make secondary adjustments (fine-tuning) to the opening of the accelerator pedal, and / or to quickly extend the push rod assembly 30 to connect with the accelerator pedal by rapidly adjusting its length, or to quickly retract the accelerator pedal control device.

[0053] In summary, the technical solution provided in this disclosure enables convenient assembly of the accelerator pedal control device and the accelerator pedal and / or fine adjustment of the accelerator pedal opening.

[0054] In some embodiments, the telescopic structure 300 includes a first telescopic structure 31, which includes a first sleeve 311 and a first rod structure 33, wherein the first sleeve 311 is lockably slidably connected to the first rod structure 33.

[0055] With the above configuration, the first sleeve 311 is lockably slidably connected to the first rod structure 33, enabling the first sleeve 311 and the first rod structure 33 to be in a locked state and a released state. When the first sleeve 311 and the first rod structure 33 are in the released state, the first rod structure 33 can slide relative to the first sleeve 311 along the extension direction of the push rod assembly 30, or in other words, the first sleeve 311 can slide relative to the first rod structure 33 along the extension direction of the push rod assembly 30, so that the first telescopic structure 31 can quickly extend, thereby enabling the push rod assembly 30 to quickly position and connect to the accelerator pedal; when the first sleeve 311 and the first rod structure 33 bracket 10 are in the locked state, the relative position between the first sleeve 311 and the first rod structure 33 can be fixed, thereby enabling the first telescopic structure 31 to maintain the adjusted length, so as to avoid slippage between the first sleeve 311 and the first rod structure 33 and affect the opening adjustment of the accelerator pedal.

[0056] In the above embodiments, when the first sleeve 311 and the first rod structure 33 are in a released state, the first rod structure 33 can slide relative to the first sleeve 311 along the extension direction of the push rod assembly 30, and can also quickly retract the accelerator pedal device.

[0057] It should be understood that the locking structure between the first sleeve 311 and the first rod structure 33 can be constructed in any suitable form. For example, the first telescopic structure 31 includes a first locking member 312 connected to the sleeve for unlockably locking the first sleeve 311 to the first rod structure 33. With this configuration, only the first locking member 312 needs to be adjusted to lock and unlock the first sleeve 311 and the first rod structure 33, making the operation simple.

[0058] In some embodiments, the first locking member 312 may be configured as a first bolt 3120, such as Figures 1 to 5As shown, the first sleeve 311 includes a first end 311a and a second end 311b. The first rod structure 33 is slidably inserted into the first sleeve 311 via the first end 311a. A first notch 3111 extending along the extension direction of the first sleeve 311 is provided on the side wall of the first end 311a of the first sleeve 311. A first threaded hole and a second threaded hole with opposite positions are provided on both sides of the first notch 3111. When it is necessary to lock the first sleeve 311 and the first rod structure 33, the first bolt 3120 can be inserted into the first threaded hole and the second threaded hole and tightened, so that the first sleeve 311 tightly clamps the first rod structure 33, thereby fixing the relative position between the first sleeve 311 and the first rod structure 33. When it is necessary to unlock the first sleeve 311 and the first rod structure 33, the first bolt 3120 inserted into the first threaded hole and the second threaded hole can be loosened, so that the first sleeve 311 and the first rod structure 33 can slide relative to each other.

[0059] In some embodiments, the telescopic structure 300 further includes a second telescopic structure 32, which includes a first rod structure 33 and a second sleeve 321. The second sleeve 321 is threadedly connected to the first rod structure 33. The relative position between the first rod structure 33 and the second sleeve 321 can be changed by rotating the second sleeve 321, so that the first rod structure 33 extends or retracts along the extension direction of the push rod assembly 30, thereby changing the length of the push rod assembly 30 and can be used to more precisely adjust the pedal opening.

[0060] In some embodiments, the second telescopic structure 32 further includes a second rod structure 322, one end of the second sleeve 321 is connected to the first rod structure 33 via a first internal thread, and the other end of the second sleeve 321 is connected to the second rod structure 322 via a second internal thread, wherein the first internal thread and the second internal thread have opposite directions of rotation.

[0061] In the above embodiment, the first rod structure 33 and the second rod structure 322 are respectively threaded to both ends of the second sleeve 321, and the first internal thread and the second internal thread have opposite directions of rotation, so that when the second sleeve 321 is rotated, the first rod structure 33 and the second rod structure 322 can simultaneously retract or extend relative to the second sleeve 321. While ensuring the adjustment accuracy of the second telescopic structure 32, it can also make the length change of the second telescopic structure 32 larger each time it is adjusted, thereby improving the adjustment efficiency.

[0062] In some embodiments, the accelerator pedal control device further includes a clamping member 40 for clamping the accelerator pedal and connected to the push rod assembly 30. This arrangement enables a stable connection between the accelerator pedal control device and the accelerator pedal, ensuring the stability of the connection between the two when the accelerator pedal control device controls the opening degree of the accelerator pedal.

[0063] In the above embodiments, the clamping member 40 can be detachably clamped to the accelerator pedal, which facilitates the disassembly and installation of the clamping member 40 and the accelerator pedal.

[0064] In some embodiments, a first universal joint 50 is provided between the push rod assembly 30 and the clamping member 40, that is, the push rod assembly 30 and the clamping member 40 can be connected through the first universal joint 50. This arrangement allows the clamping member 40 to rotate relative to the push rod assembly 30, thereby changing the installation angle of the clamping member 40 when clamping the accelerator pedal to adapt to different accelerator pedals and improve the compatibility of the accelerator pedal control device.

[0065] In other embodiments, a second universal joint 60 is provided between the push rod assembly 30 and the drive member 20. That is, the push rod assembly 30 and the drive member 20 can be connected via the second universal joint 60. This arrangement allows the push rod assembly 30 to rotate relative to the drive member 20, accommodating angular deviations between the two components caused by movement. For example, when the accelerator pedal control device is clamped to the accelerator pedal by the clamping member 40, the accelerator pedal rotates during adjustment, causing a deviation between the extension direction of the push rod assembly 30 and the driving direction of the drive member 20. The second universal joint 60 between the drive member 20 and the push rod assembly 30 can accommodate this deviation, preventing disruption to the normal operation of the accelerator pedal control device.

[0066] Of course, a second universal joint 60 is provided between the push rod assembly 30 and the drive member 20, which allows the push rod assembly 30 to rotate relative to the drive member 20 and also allows adjustment of the extension direction of the push rod assembly 30. When the driving end of the drive member 20 cannot move directly opposite the accelerator pedal, the extension direction of the assembly can be adjusted to be opposite the accelerator pedal, making it easier for the clamping member 40 connected to the push rod assembly 30 to clamp the accelerator pedal. In other words, the second universal joint 60 is provided between the push rod assembly 30 and the drive member 20, and the extension direction of the push rod assembly 30 can be flexibly adjusted according to the position between the accelerator pedal control device and the accelerator pedal, making the accelerator pedal control device more flexible to install and remove.

[0067] It should be understood that the first universal joint 50 and the second universal joint 60 described above can be constructed in any suitable manner. For example, the first universal joint 50 and the second universal joint 60 can be constructed as a universal joint.

[0068] In some embodiments, the drive unit 20 includes a linear driver 200 connected to the bracket 10. The output end of the linear driver 200 is connected to the push rod assembly 30 so as to drive the push rod assembly 30 to move. When the accelerator pedal control device is clamped to the accelerator pedal by the clamping member 40, the linear driver 200 drives the push rod assembly 30 to move, and the push rod assembly 30 can drive the accelerator pedal to rotate to adjust the opening degree of the accelerator pedal.

[0069] In the above embodiments, the linear actuator 200 can be configured in any suitable structure. For example, the linear actuator 200 can be configured as a servo electric cylinder, an electric actuator, etc., without limitation.

[0070] In some embodiments, the drive unit 20 can be controlled by a controller, which can be a handheld controller and may include components such as a touch screen and electronic control buttons. The control line of the linear drive 200 is connected to the controller, and the operation of the linear drive 200 can be controlled by the controller. It should be understood that the above-mentioned controller can be a commonly used industrial controller, which will not be described in detail here.

[0071] In some implementations, such as Figures 1 to 5 As shown, the linear actuator 200 is connected to the bracket 10. The output end of the linear actuator 200 is connected to the end of the second rod structure 322 away from the second sleeve 321 through the second universal joint 60. One end of the first rod structure 33 is inserted into the end of the second sleeve 321 away from the second rod structure 322. The first rod structure 33 is threadedly connected to the second sleeve 321. The end of the first rod structure 33 away from the second sleeve 321 is slidably connected to the first sleeve 311. The end of the first sleeve 311 away from the first rod structure 33 is connected to the clamping member 40 through the first universal joint 50.

[0072] In the above embodiment, when installing the accelerator pedal control device, the first sleeve 311 and the first rod structure 33 can be unlocked first, then the first sleeve 311 can be slid close to the accelerator pedal and clamped to the accelerator pedal by the clamping member 40. Then the first sleeve 311 and the first rod structure 33 can be locked. Then the linear actuator 200 can be controlled to run. The output end of the linear actuator 200 drives the accelerator pedal to rotate through the push rod assembly 30 to adjust the opening of the accelerator pedal. When the accelerator pedal cannot be adjusted to the preset opening by the linear actuator 200, the second sleeve 321 can be rotated to change the length of the push rod assembly 30 so as to adjust the opening of the accelerator pedal to the preset opening more accurately.

[0073] In some embodiments, the clamping member 40 may also be configured in any suitable structure. For example, the clamping member 40 includes a base plate 41, a clamping plate 42, and a clamping structure 43, which is movably connected to the base plate 41 to move toward or away from the clamping plate 42 to clamp the accelerator pedal together with the clamping plate 42, thereby achieving stable clamping between the clamping member 40 and the accelerator pedal.

[0074] In the above embodiments, the clamping member 40 clamps the accelerator pedal together through the clamping structure 43 and the clamping plate 42, thereby achieving stable clamping between the clamping member 40 and the accelerator pedal. This makes the clamping member 40 suitable for various types of accelerator pedals and improves the compatibility of the clamping member 40.

[0075] In some implementations, such as Figure 6 and Figure 7 As shown, the clamping structure 43 includes a third rod structure 431 connected to the push rod assembly 30. An adjusting member 45 is rotatably connected to the base plate 41. The adjusting member 45 is threadedly connected to the third rod structure 431 to drive the third rod structure 431 to move toward or away from the clamping plate 42, so that the third rod structure 431 and the clamping plate 42 can be detachably clamped together on the accelerator pedal.

[0076] In the above embodiment, the adjusting member 45 is threadedly connected to the third rod structure 431. Rotating the adjusting member 45 drives the third rod structure 431 to move toward or away from the clamping plate 42. With this configuration, the movement of the third rod structure 431 can be adjusted by the threaded connection between the adjusting member 45 and the third rod structure 431, which enables fine adjustment of the movement of the third rod structure 431 and facilitates the adjustment of the clamping force of the third rod structure 431 and the clamping plate 42 on the accelerator pedal.

[0077] In some implementations, such as Figure 6 and Figure 7 As shown, the substrate 41 includes a plate body 411 and a guide cylinder 412 connected to the plate body 411. An adjusting member 45 is rotatably sleeved on the end of the guide cylinder 412 away from the clamping plate 42. A third threaded hole is provided on the adjusting member 45. A third rod structure 431 passes through the third threaded hole and is threadedly connected to the adjusting member 45. One end of the third rod structure 431 is connected to the first sleeve 311 through a first universal joint 50. A buffer pad 44 is provided on the other end of the third rod structure 431. When the adjusting member 45 is rotated, the third rod structure 431 can drive the buffer pad 44 to move closer to or away from the clamping plate 42 along the extension direction of the guide cylinder 412. The guide cylinder 412 can guide the movement of the buffer pad 44, making the movement of the buffer pad 44 more stable.

[0078] In the above embodiments, the buffer pad 44 can prevent the third rod structure 431 from directly contacting the accelerator pedal and causing scratches.

[0079] Furthermore, the rotatable connection between the adjusting member 45 and the guide cylinder 412 can be constructed in any suitable form, allowing the adjusting member 45 to rotate relative to the guide cylinder 412 without disengaging from it. For example, a bearing (not shown) can be fitted around the outer circumference of the guide cylinder 412, with the adjusting member 45 fitted onto the outer ring of the bearing. The inner ring of the bearing and the guide cylinder 412 can be interference-fitted, and the outer ring of the bearing and the adjusting member 45 can also be interference-fitted, so that the adjusting member 45 can rotate relative to the guide cylinder 412 without disengaging from it during rotation.

[0080] It should be understood that the aforementioned cushioning pad 44 can be constructed in any suitable form. For example, the cushioning pad 44 can be constructed as a rubber pad or a silicone pad, without limitation.

[0081] In some embodiments, the clamping plate 42 includes at least two plates 421 connected to the base plate 41, with a gap between the at least two plates 421. This gap between the two plates 421 allows for the avoidance of accessories connected to the accelerator pedal in the vehicle, making it easier for the clamping member 40 to clamp onto the accelerator pedal. For example, when the accelerator pedal is a gas pedal, which is typically connected to the engine throttle valve via a lever, the gap between the two plates 421 allows for the avoidance of the lever, facilitating the clamping member 40 to clamp onto the gas pedal.

[0082] Furthermore, plate 421 includes a first plate portion opposite to substrate 41 and a second plate portion 4212 connected between the first plate portion and substrate 41. When clamped to the accelerator pedal by clamping member 40, the accelerator pedal can be clamped between the second plate portion 4212 and the buffer pad 44 provided in the third rod structure 431.

[0083] In some embodiments, the support 10 includes a first frame 11 and a first slide 12 movably connected to the first frame 11 along the height direction. The drive member 20 is rotatably connected to the first slide 12 so that the drive member 20 can move with the first slide 12, thereby adjusting the height of the drive member 20. The rotation axis of the drive member 20 is perpendicular to the height direction, and the pitch angle of the drive member 20 can be adjusted.

[0084] In some embodiments, the support frame 10 also includes a base 17 connected to the first frame 11. During testing, the base 17 can also be placed on the floor of the crew compartment and can be used to support the first frame 11.

[0085] In some embodiments, the bracket 10 includes a second locking member 13 that can be unlockably locked to the drive member 20 on the first slide 12 and / or the first frame 11, so that the drive member 20 can be unlockably fixed to the first slide 12 and / or the first frame 11.

[0086] In the above embodiment, when the accelerator pedal control device is in the initial installation stage, the drive component 20 can be in the unlocked state, and the height and pitch angle of the drive component 20 can be adjusted. After the adjustment is completed, the drive component 20 can be locked to the first slide 12 and the first frame 11 by the second locking component 13. The drive component 20 is fixed relative to the first frame 11, and the drive component 20 cannot be adjusted in height and angle, so as to maintain stability during the process of the accelerator pedal control device adjusting the opening of the accelerator pedal and ensure the normal operation of the accelerator pedal control device.

[0087] In some embodiments, the first frame 11 includes a first frame body 111 and a slide groove 112 disposed on the frame body 111. The first slide block 12 includes a first slide block body 122 slidably disposed in the slide groove 112 and a first gasket 121 located outside the slide groove 112. A fourth threaded hole may be provided on the first slide block body 122, and a first through hole may be provided on the first gasket 121. The second locking member 13 may be configured as a second bolt. The second bolt passes through the mounting bracket of the driving member 20 and the first through hole and is inserted into the fourth threaded hole of the first slide block body 122. The second bolt and the first slide block body 122 are threadedly connected. When the second bolt is tightened, the drive member 20, the first washer 121, and the first slide body 122 can be clamped and fixed to the first frame body 111; when the second bolt is loosened, the first slide body 122, the first washer 121, and the drive member 20 can all move along the extension direction of the first frame body 111 to realize the height adjustment of the drive member 20, and the drive member 20 can rotate relative to the first frame body 111 to realize the pitch angle adjustment of the drive member 20.

[0088] In some embodiments, the bracket 10 includes a second frame 14 detachably and movably connected to the first frame 11 to adjust its height and / or angle relative to the first frame 11. The second frame 14 serves to abut against and / or connect to the vehicle's seat assembly. This arrangement allows the second frame 14 to support the first frame 11, preventing the accelerator pedal control device from tipping away from the accelerator pedal when adjusting it.

[0089] In some embodiments, the bracket 10 includes a third locking member 15 and a second slide 16 movably connected to the first frame 11 in the height direction. The second frame 14 is provided with a mounting hole 14a. The third locking member 15 passes through the mounting hole 14a and is connected to the second slide 16. The third locking member 15 can unlockably lock the second frame 14 to the second slide 16 and / or the first frame 11.

[0090] In the above embodiment, the third locking member 15 is connected to the second slide 16 through the mounting hole 14a, enabling the second frame 14 to move relative to the first frame 11 in the height direction with the third locking member 15 and the second slide 16, and the second frame 14 to rotate relative to the first frame 11. The third locking member 15 can unlockably lock the second frame 14 to the second slide 16 and / or the first frame 11. When the third locking member 15 locks the second frame 14 to the second slide 16 and the first frame 11, the second frame 14 is fixed to the first frame 11 to ensure the stability of the second frame 14 when supporting the first frame 11. When the third locking member 15 unlocks the second frame 14 from the first frame 11 and the second slide 16, the second frame 14 can move relative to the first frame 11 in the height direction with the first slide 12, and the second frame 14 can rotate relative to the first frame 11.

[0091] In some embodiments, the mounting hole 14a is a strip-shaped hole, through which the second frame 14 can move relative to the third locking member 15. The distance by which one end of the second frame 14, which is used to abut and / or connect to the seat assembly of the vehicle, extends relative to the first frame 11 can be adjusted. When the distance between the first frame 11 and the seat assembly is different, the second frame 14 can be moved relative to the third locking member 15 to facilitate the second frame 14 abutting and / or connecting to the seat assembly of the vehicle.

[0092] In some embodiments, the second frame 14 is rotatable about the third locking member 15 with its rotation axis perpendicular to the height direction. This configuration ensures that the second frame 14 can abut against or connect to the vehicle's seat assembly regardless of the height of the third locking member 15. For example, when the third locking member 15 is at different heights, the angle between the second frame 14 and the first frame 11 needs to be changed to ensure that the second frame 14 can smoothly abut against or connect to the seat assembly. Therefore, when the height of the third locking member 15 is different, the second frame 14 can be rotated so that it can smoothly abut against or connect to the seat assembly.

[0093] In some embodiments, the second slide block 16 is slidably disposed in the slide groove 112 of the first frame 11, the third locking member 15 may be configured as a third bolt, a fifth threaded hole may be provided on the second slide groove 112, the third bolt may pass through the strip hole of the second frame 14 and be threaded into the fifth threaded hole, the third bolt and the second slide block 16 are threadedly connected, and by turning the third bolt, the second frame 14 can be unlockably locked to the second slide block 16 and / or the first frame 11.

[0094] In some embodiments, the bracket 10 further includes a third frame 18 connected to the second frame 14, and the third frame 18 is provided with a connector 19 for connecting the track of the seat assembly.

[0095] In the above-described embodiment, the second frame 14 can be connected to the track of the seat assembly via the third frame 18, which makes the connection between the second frame 14 and the seat assembly more stable. In this way, the second frame 14 can stably support the first frame 11 and prevent the accelerator pedal control device from tilting away from the accelerator pedal when it is in operation.

[0096] In some embodiments, the connector 19 can be constructed in any suitable form. For example, the connector 19 includes an actuator 191 and a deformable element 192, the deformable element 192 being fixedly connected to the third frame 18, and the actuator 191 being used to drive the deformable element 192 to deform and abut against the track, thereby locking the connector 19 to the track and achieving a stable connection between the third frame 18 and the track.

[0097] In some embodiments, the actuator 191 is movably connected to the third frame 18, and is located between two pairs of deformable elements 192. The two deformable elements 192 are respectively fixedly connected to the third frame 18. Two inclined surfaces of the actuator 191 and the two deformable elements 192 that abut against each other extend towards or away from each other along the direction of movement of the actuator 191. With this configuration, when the actuator 191 moves, the deformable elements 192 located on both sides of the actuator 191 can be compressed and deformed in a direction away from the actuator 191, or the deformable elements 192 can return to their original shape. When the connector 19 connects to the track, the actuator 191 and the deformable elements 192 can be simultaneously inserted into the groove of the track, and then the actuator 191 is moved towards the third frame 18. The deformable elements 192 on both sides of the third frame 18 can deform and abut against the two opposite sidewalls of the groove of the track, so that the connector 19 is fixed in the groove of the track.

[0098] In some embodiments, the actuator 191 can be movably connected to the third frame 18 in any suitable manner. For example, a nut 110 can be fixedly connected to the third frame 18, and the connector 19 further includes a stud 193 rotatably connected to the actuator 191. The stud 193 passes through the nut 110 and is threadedly engaged with the nut 110. The stud 193 can be rotated so that the actuator 191 can move closer to or away from the third frame 18.

[0099] In the above embodiments, the rotational connection between the stud 193 and the actuator 191 can be implemented in any suitable form. For example, a limiting hole can be opened at one end of the actuator 191, and a bearing can be installed in the limiting hole. The outer ring of the bearing is interference-fitted with the inner wall of the limiting hole. The bearing is sleeved on one end of the stud 193, and the inner ring of the bearing is interference-fitted with the stud 193.

[0100] It should be understood that the aforementioned actuator 191 can be constructed as an iron block or a plastic block, etc., and there is no limitation here. The aforementioned deformable component 192 is made of metal or plastic, as long as it can realize the function of the aforementioned deformable component 192, and there is no limitation here.

[0101] In some embodiments, the third frame 18 is positionally adjustable to the second frame 14, enabling a stable connection between the second frame 14 and the third frame 18 regardless of the position of the accelerator pedal control device within the vehicle.

[0102] In the above implementation methods, such as Figure 9 and Figure 10 As shown, the third frame 18 includes a fixed part 181 spaced apart and a connecting part 182 connected to the two fixed parts 181. When the third frame 18 abuts against the seat assembly, the two connecting parts 182 can abut against the two tracks of the seat assembly respectively. The connector 19 can be provided on the fixed part 181 of the third frame 18, and the third frame 18 is connected to the track through the connector 19.

[0103] Furthermore, multiple fixing screw holes 18a can be spaced apart on the connecting part 182 of the third frame 18. The multiple fixing screw holes 18a can be spaced apart along the connecting part 182 of the third frame 18. The second frame 14 includes a second frame body 141 and a fixing plate 142 connected to the second frame body 141. A strip-shaped hole is opened on the second frame body 141, and a waist-shaped hole 14b can be opened on the fixing plate 142. Bolts can be inserted through the waist-shaped hole 14b and the fixing screw holes 18a, and the bolts are threadedly engaged with the fixing screw holes 18a, so that the fixing plate 142 and the third frame 18 can be detachably connected, thereby making the second frame 14 detachably connected to the third frame 18. Through the cooperation between the waist-shaped hole 14b of the fixing plate 142 and different fixing screw holes 18a, the connection position of the third frame 18 and the second frame 14 can be adjusted so that the third frame 18 is detachably connected to the second frame 14.

[0104] The following is an exemplary description of the installation and adjustment process of the accelerator pedal control device, in conjunction with... Figures 1 to 10 .

[0105] First, adjust the position of the test vehicle's seat. Then, place the accelerator pedal control device inside the test vehicle's passenger compartment. Place the base 17 on the passenger compartment floor. Adjust the second frame 14. Then, the third frame 18, connected to the second frame 14, abuts against the seat assembly and is connected to the seat assembly's track via the connector 19. Next, adjust the drive member 20, configured as a linear actuator 200, to move it in the height direction to a suitable position on the first frame 11. Tighten the first bolt 3120 and the first locking member 312 on the first sleeve 311 to release the first rod structure 33. Manually slide the first sleeve 311 relative to the first... A rod structure 33 extends, and the extension length of the first sleeve 311 is quickly adjusted so that the clamping member 40 connected to the first sleeve 311 quickly approaches the accelerator pedal. The adjusting member 45 is turned to clamp the accelerator pedal between the clamping plate 42 and the buffer pad 44. Then, the first locking member 312, which is a first bolt 3120, is turned to lock the first sleeve 311 to the first rod structure 33. Then, the driving member 20 is controlled to operate to adjust the opening of the accelerator pedal. If the pedal cannot be adjusted to the preset opening by the driving member 20, the second sleeve 321 can be turned to achieve a more precise adjustment of the accelerator pedal to adjust the opening of the accelerator pedal to the preset opening.

[0106] It should be understood that this accelerator pedal control device can be used in conjunction with other testing equipment. The accelerator pedal opening can be adjusted via this device, and accurate data can be collected using other testing equipment. This accelerator pedal adjustment device can be applied to various test scenarios requiring control of the accelerator pedal opening, such as constant speed vehicle testing, accelerator pedal opening testing, vehicle mileage endurance testing, and engine torque analysis testing.
