Description

Technical Field

[0001] The invention belongs to the technical field of automobile bodies, and in particular relates to a device for simulating an accelerator pedal of a straight-plate commercial vehicle. Background Art

[0002] When designing the passenger compartment during vehicle body design, the placement of the accelerator pedal is closely linked to the human body's operating posture. Once the footrest angle and ankle joint angle are determined, the target user's lower limb posture is largely defined. Furthermore, the placement of other pedals is also guided by the accelerator pedal. Therefore, the placement of the accelerator pedal has a significant impact on lower limb comfort.

[0003] With the widespread adoption of independent development, domestic OEMs are experimenting with and accumulating the effectiveness of various design solutions. One approach is to integrate development with research. Therefore, man-machine test benches are often used for research, with pedal comfort and comfortable operating posture being key areas of study. Furthermore, existing designs for straight-type commercial vehicle accelerator pedals are mostly tailored to specific vehicle models. As mentioned above, the accelerator pedal layout needs to be adjusted accordingly based on the driver's operating posture, making the application of accelerator pedals designed for a single vehicle model very limited. New design solutions also require experimental evaluation, verification, and optimization. Similarly, independent design of driver space layouts often involves exploring innovative solutions or adjusting existing ones. Incorporating man-machine test benches can greatly enhance this effort. To enable the reproduction, evaluation, adjustment, and rapid evaluation of different vehicle models and design solutions on a man-machine test bench, a device with variable key design parameters is required to simulate the pedal mechanism. To this end, we propose a device for simulating the accelerator pedal of a straight-type commercial vehicle. Summary of the Invention

Implementation Method

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0023] like Figure 1-3 As shown, a device for simulating a straight-type commercial vehicle accelerator pedal provided by one embodiment of the present invention includes a pedal 1, a hinge 2, and a connecting plate 3, and further includes:

[0024] An adjustment mechanism, one end of which is connected to the pedal 1, and the other end of which is connected to the connecting plate 3. The adjustment mechanism includes a spring adjustment structure and a pedal opening angle adjustment structure. The spring adjustment structure includes a spring 8. The spring adjustment structure is used to adjust the tightness of the spring 8. The pedal opening angle adjustment structure is used to adjust the opening angle of the pedal 1.

[0025] The limiting block 4 is provided on the connecting plate 3 , and is used to adjust the installation angle of the pedal 1 .

[0026] In the embodiment of the present invention, the present invention adjusts the tightness of the spring 8 by adopting a spring adjustment structure, adjusts the opening angle of the pedal 1 by adopting a pedal opening angle adjustment structure, and adjusts the installation angle of the pedal 1 by adopting a limit block 4 with an arc groove 18. The mechanism is simple, practical, and fully adjustable, and can accurately simulate the straight-plate accelerator pedals of different models. The structure is easy to implement, low in cost, and easy to install and use.

[0027] like Figure 1 As shown, as a preferred embodiment of the present invention, the spring adjustment structure also includes a vertical plate 5, a slider 6 and a positioning shaft 7, the vertical plate 5 and the slider 6 are connected by a locking bolt 16 and a locking bolt 2 17, and the vertical plate 5 is fixedly connected to the connecting plate 3; the positioning shaft 7 is fixedly set on the slider 6, and a spring 8 is sleeved on the positioning shaft 7, one end of the spring wire of the spring 8 contacts the pedal 1 under the action of elastic force, and the other end of the spring wire of the spring 8 contacts the connecting plate 3 under the action of elastic force.

[0028] In an embodiment of the present invention, the preferred method for adjusting spring 8 is as follows: by adjusting slider 6, positioning shaft 7 moves with slider 6, which in turn drives spring 8. As the position of spring 8 changes, the stiffness of spring 8 also changes, thereby adjusting the pedaling force. The further forward slider 6 moves (toward hinge 2), the tighter spring 8 becomes, and the required pedaling force increases. The further rearward slider 6 moves (away from hinge 2), the looser spring 8 becomes, and the required pedaling force decreases. Once adjustment is complete, tighten locking bolt 16 and locking bolt 2 17 to lock the pedal.

[0029] like Figure 1-3 As shown, as a preferred embodiment of the present invention, the pedal opening angle adjustment structure includes a limit plate 9, a hinge 2 10, a pad 11, an inclination angle adjustment bolt 12 and a height adjustment bolt 13, the inclination angle adjustment bolt 12 is fixedly connected to the pedal 1, and the height adjustment bolt 13 is fixedly connected to the connecting plate 3; the axis of the hinge 2 10 is fixedly connected to the slider 6, one side of the hinge 2 10 is connected to the limit plate 9, and the other side of the hinge 2 10 is connected to the pad 11.

[0030] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present invention, the nut of the tilt angle adjustment bolt 12 is close to the limiting plate 9 , and the nut of the height adjustment bolt 13 is located on the upper side of the limiting plate 9 .

[0031] In an embodiment of the present invention, the inclination angle of the pedal 1 is preferably adjusted by adjusting the nut on the inclination angle adjustment bolt 12, which abuts the stop plate 9, to achieve different initial angles of the pedal 1. The initial angle of the pedal 1 can also be changed by adjusting the uppermost position of the stop plate 9 by adjusting the nut on the height adjustment bolt 13, located above the stop plate 9. Specifically, the opening angle of the pedal 1 is adjusted as follows: adjusting the nut on the inclination angle adjustment bolt 12 adjusts the inclination of the stop plate 9; adjusting the nut on the height adjustment bolt 13 adjusts the height of the stop plate 9. Hinge 2 10 and pad 11 below the stop plate 9 act as a support. As the height of the stop plate 9 changes, the opening angle of hinge 2 10 can be adjusted to accommodate changes in the height. The lower the stop plate 9 is and the more it tilts backward, the smaller the opening angle of the pedal 1 is. The higher the stop plate 9 is and the more it tilts forward, the larger the opening angle of the pedal 1 is, thereby achieving different initial angles of the pedal 1.

[0032] like Figure 1 and Figure 2 As shown in FIG. 1 , as a preferred embodiment of the present invention, the limit block 4 is connected to the connecting plate 3 via a limit bolt 14 , and an arc-shaped groove 18 is formed on the limit block 4 .

[0033] In the embodiment of the present invention, the bottoming position of the pedal 1 can preferably be set by adjusting the height of the limit bolt 14 on the limit block 4. When the pedal 1 is bottomed out, the tilt angle adjustment bolt 12 collides with the limit bolt 14 on the limit block 4, thereby limiting further depression. Specifically, by adjusting the height of the limit bolt 14 so that the tilt angle adjustment bolt 12 collides with the limit bolt 14 when the pedal 1 is bottomed out, the bottoming angle is set.

[0034] like Figure 1-3 As shown in FIG. 1 , as a preferred embodiment of the present invention, the connecting plate 3 is provided with an arcuate groove 18 which is the same as the arcuate groove 18 on the limiting block 4 .

[0035] In an embodiment of the present invention, the installation angle can preferably be adjusted according to the needs of different vehicle models. The so-called installation angle refers to the angle at which the entire pedal assembly rotates clockwise (when viewed from above) around the vertical axis passing through the limit bolt 14. Actual straight-type accelerator pedals generally have this angle. Specifically, the specific operation for adjusting the installation angle is as follows: Since both the connecting plate 3 and the limit block 4 have arc-shaped grooves 18, the limit bolt 14 can move along the trajectory of the arc-shaped grooves 18. Properly loosening the nut of the limit bolt 14 can cause the entire pedal assembly to rotate clockwise (when viewed from above) around the vertical axis of the limit bolt 14, thereby adjusting the installation angle. After adjustment, tighten the nut of the limit bolt 14 to lock the pedal assembly.

[0036] like Figure 1 As shown in FIG. 1 , as a preferred embodiment of the present invention, the connecting plate 3 is mounted on the vehicle body floor via mounting bolts 15 .

[0037] The working principle of the present invention is:

[0038] This device, used to simulate a straight-type commercial vehicle accelerator pedal, adjusts spring 8 by moving slider 6, which in turn moves positioning shaft 7, which in turn drives spring 8. As the position of spring 8 changes, its stiffness also changes, thereby adjusting the pedaling force. The further forward slider 6 moves, the tighter spring 8 becomes, increasing the required pedaling force. The further back slider 6 moves, the looser spring 8 becomes, decreasing the required pedaling force. Once adjustment is complete, tighten locking bolts 16 and 17 to lock the pedal.

[0039] The specific operation of adjusting the opening angle of the pedal 1 is as follows: connect the device to the vehicle body floor via the connecting plate 3 with the mounting bolts 15, adjust the nut on the tilt angle adjustment bolt 12 to adjust the inclination of the limit plate 9; adjust the nut on the height adjustment bolt 13 to adjust the height of the limit plate 9, and the hinge 2 10 and the pad 11 under the limit plate 9 play a supporting role. When the height of the limit plate 9 changes, the opening angle of the hinge 2 10 can be adjusted to adapt to it. The lower the height of the limit plate 9 and the more it tilts backward, the smaller the opening angle of the pedal 1; the higher the height of the limit plate 9 and the more it tilts forward, the larger the opening angle of the pedal 1, thereby achieving different initial angles of the pedal 1.

[0040] The specific operation for adjusting the installation angle is as follows: since arc grooves 18 are provided on the connecting plate 3 and the limit block 4, the limit bolt 14 can move along the trajectory of the arc groove 18. By loosening the nut of the limit bolt 14 appropriately, the entire pedal device can be rotated clockwise (when viewed from above) around the vertical axis of the limit bolt 14, thereby adjusting the installation angle. After the adjustment is completed, tighten the nut of the limit bolt 14 to achieve locking.

[0041] In actual application, the three adjustment methods can be combined to adjust according to the needs of the vehicle model, so that the accelerator pedal of the device can meet various needs.

[0042] The above are only preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several variations and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
