Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to an electric foot pedal and a vehicle. Background Art

[0002] In order to improve the convenience of getting on and off the vehicle, medium and large vehicles such as SUVs, MPVs, and off-road vehicles are usually equipped with electric foot pedals, such as Figure 1 As shown, the electric foot pedal generally includes a pedal panel 101 and a power mechanism 102. Both ends of the pedal panel 101 are movably connected to a vehicle body 105 via a movable connection mechanism 103. The power mechanism 102 drives the pedal panel 101 to move, thereby extending and retracting the pedal panel 101.

[0003] Due to the limitation of the structure of the vehicle, the power mechanism 102 is usually installed offset and is only connected to the movable connection mechanism 103 arranged at the first end of the tread panel 101. The movable connection mechanism 103 arranged at the first end of the tread panel 101 is self-locked by the self-locking of the power mechanism 102, so as to ensure the position stability of the first end of the tread panel 101. The movable connection mechanism 103 arranged at the second end of the tread panel 101 has no self-locking structure. Therefore, when the tread panel 101 is in the retracted state, the second end of the tread panel 101 pulls the movable connection mechanism 103 arranged at the second end of the tread panel 101 to move under the action of gravity, thereby causing the second end of the tread panel 101 to fall under the action of gravity (such as Figure 1 As shown by the middle dotted line, a displacement deviation da occurs, resulting in an eight-shaped gap 106 between the tread surface 104 of the tread panel 101 and the vehicle body 105, which affects the appearance of the vehicle and the user's experience. Summary of the invention

[0004] In view of this, the present application provides an electric foot pedal and a vehicle, which can effectively compensate for the falling amount of the end of the pedal panel away from the power mechanism in the retracted state, reduce the height difference between the two ends of the pedal panel and the mounting surface of the vehicle body, and enhance the user experience.

[0060] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0061] like Figure 2-Figure 15 As shown, the embodiment of the present application provides an electric foot pedal for installation on a vehicle body. The electric foot pedal comprises a pedal panel 1, a first movable connection mechanism 2, a second movable connection mechanism 3 and a power mechanism 4.

[0062] The tread panel 1 has a tread surface 11, and the tread surface 11 is used for a user to tread on.

[0063] The first movable connecting mechanism 2 is connected to the first end of the pedal panel 1, and the second movable connecting mechanism 3 is connected to the second end of the pedal panel 1. The first movable connecting mechanism 2 has a first connecting surface 2111 for fixedly connected to the vehicle body, and the second movable connecting mechanism 3 has a second connecting surface 3111 for fixedly connected to the vehicle body. The plane where the first connecting surface 2111 and the second connecting surface 3111 are located is the first mounting surface 7 of the electric foot pedal, and the vehicle body includes a second mounting surface. The first connecting surface 2111 and the second connecting surface 3111 are used to fit and fix with the second mounting surface of the vehicle body, that is, the first mounting surface 7 fits parallel to the second mounting surface.

[0064] The first movable connecting mechanism 2 and the second movable connecting mechanism 3 are both movable connecting parts. The movement of the first movable connecting mechanism 2 and the second movable connecting mechanism 3 can drive the pedal panel 1 to switch between an extended state and a retracted state relative to the first connecting surface 2111 and the second connecting surface 3111, that is, when the electric foot pedal is installed on the vehicle body, it can drive the pedal panel 1 to switch between an extended state and a retracted state relative to the vehicle body.

[0065] When the pedal panel 1 switches from the retracted state to the extended state, the pedal panel 1 moves along the height direction X in a direction in which the distance from the first mounting surface 7 increases, and produces a vertical downward displacement when the electric pedal is installed on the vehicle body; and moves along the width direction Y in a direction away from the inner side surface b of the electric pedal, and produces an outward displacement relative to the vehicle body when the electric pedal is installed on the vehicle body.

[0066] It should be noted that the height direction X refers to the direction perpendicular to the first mounting surface 7. When the electric step is mounted on the vehicle body, the height direction X may be a vertical direction, or, in other embodiments, a direction having an angle with the horizontal direction that is not equal to 0° and 90°. The width direction Y refers to the direction from the inner side a to the outer side b of the electric step. When the electric step is mounted on the vehicle body, the width direction Y refers to the direction between the two side doors of the vehicle that are away from each other.

[0067] The power mechanism 4 is connected to the first movable connection mechanism 2, and the power mechanism 4 is used to drive the first movable connection mechanism 2 to move, so that the first movable connection mechanism 2 drives the pedal panel 1 to switch between the extended state and the retracted state.

[0068] The height of the first movable connection mechanism 2 is greater than that of the second movable connection mechanism 3 , that is, taking the first mounting surface 7 as the mounting reference surface, the mounting height of the second end of the tread panel 1 is raised compared to the first end of the tread panel 1 .

[0069] It should be noted that the height of the first movable connection mechanism 2 refers to the overall height of the first movable connection mechanism 2, that is, the distance between the two outermost surfaces of the first movable connection mechanism 2 along the height direction X, such as Fig.14 The height of the second movable connection mechanism 3 refers to the overall height of the second movable connection mechanism 3, that is, along the height direction X, the distance between the two surfaces of the second movable connection mechanism 3 at the edge, such as Figure 6 As shown in e2.

[0070] It should be noted that the height of the first movable connection mechanism 2 being greater than the height of the second movable connection mechanism 3 means that, when not affected by external forces, the height of the first movable connection mechanism 2 is greater than the height of the second movable connection mechanism 3 in the same state.

[0071] Please refer to Fig.12 , Fig.12 This is a schematic diagram of the structure of the electric foot pedal in the retracted state. Fig.12 The second movable connection mechanism 3 and the tread panel 1 shown in the middle dotted line segment represent the position schematic diagram of the second movable connection mechanism 3 and the tread panel 1 when they are not affected by external forces.

[0072] When the electric foot pedal is installed on the vehicle body, the first movable connection mechanism 2 is connected to the power mechanism 4, and the self-locking of the power mechanism 4 is used to form a self-locking, so that the first movable connection mechanism 2 can be maintained at an ideal height. The second movable connection mechanism 3 is not connected to the power mechanism 4. Therefore, in the retracted state, the second movable connection mechanism 3 will produce a certain extension movement under the gravity of the pedal panel 1 and its own gravity, thereby causing the second end of the pedal panel 1 to move db away from the first mounting surface 7, which offsets the raised mounting height of the second end of the pedal panel 1, so that the distance between the first end of the pedal panel 1 and the first mounting surface 7 and the distance between the second end of the pedal panel 1 and the first mounting surface 7 meet the equal condition, such as Fig.12 The tread panel 1 and the second movable connection mechanism 3 shown by the solid line segment in the figure can reduce the height difference between the two ends of the tread panel 1 and the second mounting surface of the vehicle body.

[0073] It should be noted that the distance between the first end of the tread panel 1 and the first mounting surface 7 and the distance between the second end of the tread panel 1 and the first mounting surface 7 satisfying the equality condition means that the distance between the first end of the tread panel 1 and the first mounting surface 7 and the distance between the second end of the tread panel 1 and the first mounting surface 7 are equal, or the distance between the first end of the tread panel 1 and the first mounting surface 7 and the distance between the second end of the tread panel 1 and the first mounting surface 7 are approximately equal. For example, the difference between the distance between the first end of the tread panel 1 and the first mounting surface 7 and the distance between the second end of the tread panel 1 and the first mounting surface 7 is maintained within the range of engineering requirements.

[0074] It should be noted that the distance from the first end of the tread panel 1 to the first mounting surface 7 refers to the distance from the center of the connection area between the tread panel 1 and the first movable connection mechanism 2 to the center of the first connection surface 2111 along the height direction X. Similarly, the distance from the second end of the tread panel 1 to the first mounting surface 7 refers to the distance from the center of the connection area between the tread panel 1 and the second movable connection mechanism 3 to the first mounting surface 7 along the height direction X.

[0075] In the electric pedal provided in the embodiment of the present application, by designing the height of the first movable connection mechanism 2 to be greater than the second movable connection mechanism 3, the installation height of the second end of the pedal panel 1 is raised. When the electric pedal is installed on the vehicle body, the amount of fall of the second end of the pedal panel 1 due to gravity in the retracted state is compensated, and the amount of fall of the second end is reduced or eliminated. It can be seen that the electric pedal in the embodiment of the present application can effectively compensate for the fall of the end of the pedal panel away from the power mechanism in the retracted state, reduce the height difference between the two ends of the pedal panel and the installation surface of the vehicle body, and improve the user experience.

[0076] In a preferred embodiment, when the electric foot pedal is mounted on the vehicle body and is in a retracted state, the distance between the first end of the tread panel 1 and the first mounting surface 7 along the height direction X can be equal to the distance between the second end of the tread panel 1 and the first mounting surface 7. This structure can completely eliminate the amount of fall of the second end of the tread panel 1 in the retracted state, eliminate the height difference between the two ends of the tread panel 1 and the second mounting surface of the vehicle body, and maximize the user experience.

[0077] The first movable connection mechanism 2 may include a first connecting rod mechanism 22 and a first connecting member 21 for connecting to the vehicle body. One end of the first connecting rod mechanism 22 may be rotatably connected to the first connecting member 21 , and the other end may be rotatably connected to the pedal panel 1 . The first connecting member 21 has a first connecting surface 2111 .

[0078] The second movable connection mechanism 3 may include a second connecting rod mechanism 32 and a third connecting member 31 for connecting to the vehicle body. One end of the second connecting rod mechanism 32 is rotatably connected to the third connecting member 31 , and the other end is rotatably connected to the pedal panel 1 . The third connecting member 31 has a second connecting surface 3111 .

[0079] In this case, the first movable connection mechanism 2 realizes movement through the first connecting rod mechanism 22, and the second movable connection mechanism 3 realizes movement through the second connecting rod mechanism 32. The connecting rod mechanism has a simple structure, high flexibility, strong adaptability, and can realize various forms of movement.

[0080] In an optional embodiment, the first connecting member 21 can be a block-shaped structure, one of whose surfaces can form a first connecting surface 2111, and the first connecting rod mechanism 22 can be rotatably connected to the block-shaped structure via a rotating shaft. Similarly, the third connecting member 31 can be a block-shaped structure, one of whose surfaces can form a second connecting surface 3111, and the second connecting rod mechanism 32 can be rotatably connected to the block-shaped structure via a rotating shaft.

[0081] In another optional embodiment, the first connecting member 21 may include a first connecting plate 211 and a first ear plate 212 which are vertically fixedly connected, the first connecting plate 211 having a first connecting surface 2111, two first ear plates 212 being connected to the first connecting plate 211 at intervals, the two first ear plates 212 being provided with through holes, one end of the first connecting rod mechanism 22 being provided with a through hole, one end of the first connecting rod mechanism 22 extending between the two first ear plates 212, the through hole of the first ear plate 212 being opposite to the through hole of the first connecting rod mechanism 22, the rotating connecting member passes through the through holes of the two first ear plates 212 and the through holes of the first connecting rod mechanism 22, so as to realize the rotating connection between one end of the first connecting rod mechanism 22 and the first ear plate 212.

[0082] The third connecting member 31 may include a second connecting plate 311 and a second ear plate 312 which are vertically fixedly connected. The second connecting plate 311 has a second connecting surface 3111. There are two second ear plates 312 which are connected to the second connecting plate 311 at intervals. The two second ear plates 312 are provided with through holes. One end of the second connecting rod mechanism 32 is provided with a through hole. One end of the second connecting rod mechanism 32 extends between the two second ear plates 312. The through holes of the second ear plate 312 are opposite to the through holes of the second connecting rod mechanism 32. The rotating connecting member passes through the through holes of the two second ear plates 312 and the through holes of the second connecting rod mechanism 32 to realize the rotating connection between one end of the second connecting rod mechanism 32 and the second ear plate 312.

[0083] The weight of the first connecting member 21 and the third connecting member 31 of this structure is reduced compared to the first connecting member 21 and the third connecting member 31 of the block structure, which contributes to the lightweight design of the electric foot pedal. The rotational connection with the first connecting rod mechanism 22 is achieved through the two first ear plates 212, which helps to improve the connection stability between the first connecting member 21 and the first connecting rod mechanism 22. Similarly, the rotational connection with the second connecting rod mechanism 32 is achieved through the two second ear plates 312, which helps to improve the connection stability between the third connecting member 31 and the second connecting rod mechanism 32.

[0084] There are various structures for achieving that the height of the first movable connection mechanism 2 is greater than the height of the second movable connection mechanism 3 .

[0085] In the first optional embodiment, please refer to Fig.13, material can be cut off from the second movable connecting mechanism 3, for example, the cutting height dc. After the cutting, the height of the second movable connecting mechanism 3 is reduced by dc compared with the first movable connecting mechanism 2, so that the height of the first movable connecting mechanism 2 is greater than the height of the second movable connecting mechanism 3, and the height of the second end of the treading panel 1 connected to the second movable connecting mechanism 3 is raised, thereby reducing or eliminating the falling amount of the second end of the treading panel 1 in the retracted state.

[0086] Specifically, the second connecting plate 311 may be cut off so that the thickness d1 of the first connecting plate 211 is greater than the thickness d2 of the second connecting plate 311 . This method has a simple structure, is easy to process, and is reliable.

[0087] It should be noted that, in the first optional embodiment, except for the different thicknesses of the first connecting plate 211 and the second connecting plate 311 , other structures and dimensions of the first movable connecting mechanism 2 and the second movable connecting mechanism 3 are the same.

[0088] In a second optional embodiment, the rotational connection position of the first connecting rod mechanism 22 and the first connecting member 21 is located on the straight line where the first connecting line 223 is located, and the rotational connection position of the second connecting rod mechanism 32 and the third connecting member 31 is located on the straight line where the second connecting line 323 is located. Along the width direction Y, the electric foot pedal has an inner side surface a and an outer side surface b that are distributed opposite to each other. Along the height direction X, the distance between the center of the first connecting line 223 and the first mounting surface 7 is greater than the distance between the center of the second connecting line 323 and the first mounting surface 7. Along the width direction Y, the distance between the center of the first connecting line 223 and the outer side surface b is greater than the distance between the center of the second connecting line 323 and the outer side surface b.

[0089] Please refer to Fig.14 The inner side a refers to the vertical plane where the edge of the electric foot pedal facing inside the vehicle is located when the electric foot pedal is installed on the vehicle body, and the outer side b refers to the vertical plane where the edge of the electric foot pedal facing outside the vehicle is located.

[0090] It can be seen that in the embodiment of the present application, compared with the rotation connection position of the first link mechanism 22 and the first connecting member 21 (such as Fig.14 The first connecting line 223 in FIG. 1 ), the rotation connection position of the second link mechanism 32 and the third connecting member 31 (such as Fig.14 The second connecting line 323 in the figure moves upward along the height direction X and outward along the width direction Y to raise the height of the second end of the tread panel 1 connected to the second movable connecting mechanism 3, reduce or eliminate the falling amount, and ensure the smoothness of the movement of the tread panel 1 during the extension or retraction process.

[0091] It should be noted that, in the second optional embodiment, except that the rotational connection position of the first connecting rod mechanism 22 and the first connecting member 21 is different from the rotational connection position of the second connecting rod mechanism 32 and the third connecting member 31, the other structures and dimensions of the first movable connecting mechanism 2 and the second movable connecting mechanism 3 are the same.

[0092] It should be noted that Fig.14 The dashed line segments 223 and 323 in FIG. 1 are virtual straight lines, not straight lines actually existing on the electric foot pedal.

[0093] Please refer again Fig.14 The first link mechanism 22 may include a first driving link 221 and a first supporting link 222. One end of each of the first driving link 221 and the first supporting link 222 is rotatably connected to the first connecting member 21, and the other end is rotatably connected to the tread panel 1. The first driving link 221 is connected to the output shaft 41 of the power mechanism 4. The power mechanism 4 can drive the first driving link 221 to rotate, thereby driving the tread panel 1 to extend and retract. In this case, the first supporting link 222 can improve the relative position stability between the first connecting member 21 and the tread panel 1.

[0094] Please refer again Figure 6 and Fig.14 The second connecting rod mechanism 32 includes a second driving connecting rod 321 and a second supporting connecting rod 322. One end of the second driving connecting rod 321 and the second supporting connecting rod 322 are rotatably connected to the third connecting member 31, and the other end is rotatably connected to the pedal panel 1. When the power mechanism 4 drives the first driving connecting rod 221 to rotate and drives the pedal panel 1 to extend and retract, the second connecting rod mechanism 32 moves under the drive of the pedal panel 1 and plays a role of supporting the second end of the pedal panel 1.

[0095] The rotational connection position between the first connecting rod mechanism 22 and the first connecting member 21, that is, the rotational connection position between the first driving connecting rod 221 and the first connecting member 21, and the connection position between the first supporting connecting rod 222 and the first connecting member 21 is the first connecting line 223, and the rotational connection position between the second connecting rod mechanism 32 and the third connecting member 31, that is, the rotational connection position between the second driving connecting rod 321 and the third connecting member 31, and the connection position between the second supporting connecting rod 322 and the third connecting member 31 is the second connecting line 323.

[0096] Of course, in other optional embodiments, the first link mechanism 22 may also include other links except the first driving link 221 and the first supporting link 222. The second link mechanism 32 may also include other links except the second driving link 321 and the second supporting link 322.

[0097] In the embodiment of the present application, the first connecting line 223 has an included angle α with the second connecting line 323 in the clockwise direction to compensate for the outward tendency of the end of the pedal panel 1 not equipped with the power mechanism 1 in the width direction of the vehicle caused by the upward and outward movement of the second connecting line 323 relative to the first connecting line 223, that is, to tighten the end of the pedal panel 1 not equipped with the power mechanism 1 inward.

[0098] It should be noted that the angle α between the first line 223 and the second line 323 along the clockwise direction means that, with the straight line where the first line 223 is located as the starting end, the straight line where the second line 323 is located as the end, and the intersection of the first line 223 and the straight line where the second line 323 is located as the rotation center, the angle of rotation when the straight line where the first line 223 is located is rotated in the clockwise direction to the position of the straight line where the second line 323 is located is α.

[0099] In a specific design process, when the position of the first connecting line 223, the angle α between the first connecting line 223 and the second connecting line 323, and the position of one of the end points of the second connecting line 323 are known, the position of the other end point of the second connecting line 323 can be calculated. For example, when the position of the first connecting line 223, the distance of the first end point of the second connecting line 323 (which can be the rotational connection position of the second driving connecting rod 321 and the third connecting member 31) from the first connecting line 223 along the height direction X (for example, 0.512 mm), the distance of the first end point of the second connecting line 323 from the first connecting line 223 along the width direction Y (for example, 1.578 mm), and the angle α between the first connecting line 223 and the second connecting line 323 (for example, 1.064°), the position of the second end point of the second connecting line 323 (which can be the rotational connection position of the second supporting connecting rod 322 and the third connecting member 31) can be calculated.

This connection method can reduce the adverse effects of drilling holes on the output shaft 41 on parameters such as the strength of the output shaft 41 .

[0103] The other end of the first link mechanism 22 is rotatably connected to the pedal panel 1 , and there are many ways in which the other end of the second link mechanism 32 is rotatably connected to the pedal panel 1 .

[0104] In an optional embodiment, the first drive link 221 and the first support link 222 of the first link mechanism 22 can be rotatably connected to the pedal panel 1 through a rotating connection such as a rotating shaft, or the pedal panel 1 can be provided with a first protrusion, and the first drive link 221 and the first support link 222 can be rotatably connected to the first protrusion through a rotating connection such as a rotating shaft; the second drive link 321 and the second support link 322 of the second link mechanism 32 can be directly rotatably connected to the pedal panel 1, or the pedal panel 1 can be provided with a second protrusion, and the second drive link 321 and the second support link 322 can be rotatably connected to the second protrusion through a rotating connection such as a rotating shaft.

[0106] The second movable connection mechanism 3 also includes a fourth connecting member 34, and the other end of the second connecting rod mechanism 32 (that is, the other end of the second driving connecting rod 321 and the second supporting connecting rod 322) is rotatably connected to the fourth connecting member 34. The fourth connecting member 34 is pin-connected to the pedal panel 1 and protrudes from the pedal panel 1 so that the other end of the second connecting rod mechanism 32 is rotatably connected to the pedal panel 1 through the fourth connecting member 34.

[0107] This structure makes it easier to install the first movable connection mechanism 2 and the second movable connection mechanism 3 on the tread panel 1 .

[0109] In the process of designing an electric foot pedal, the amount of fall of the second end of the pedal panel 1 in an electric foot pedal for which compensation design has not been performed can be identified in advance through model tools such as CAE (Computer-Aided Engineering) / anti-torsion deformation / platform design experience values, and compensation design can be performed based on the calculated fall amount. The compensation design is to design the thickness difference between the first connecting plate 211 and the second connecting plate 311, or to design the positional relationship between the first connecting line 223 and the second connecting line 323.

[0110] Specifically, the electric pedal can be simplified as a cantilever beam model (such as Fig.11 ), the calculation of the anti-torque displacement of the cantilever beam can be derived from the elastic mechanical properties. In a simple case, the relationship between shear stress and torque can be used to estimate the anti-torsion displacement of the cantilever beam. Assuming that the length of the cantilever beam is L and it is subjected to torque T, its torsion angle θ can be approximately calculated by the following formula:

[0111] θ=T×L / G×J

[0112] Where: θ is the torsion angle (the angle between the first mounting surface 7 and the treading surface 11 when no compensation design is performed), T is the torque (the gravity of the treading panel 1), L is the cantilever beam length (the distance between the first movable connection mechanism 2 and the second movable connection mechanism 3), G is the material shear modulus of the treading panel 1, and J is the torsion constant or torsional moment of inertia of the interface (a geometric parameter that depends on the shape and size of the beam. For a rectangular cross section, J can be calculated by the formula, for example, for a rectangular cross section J = b × h^3 / 12, where b and h are the width and height of the cross section, respectively.)

[0113] It can be seen from the formula that the torsion angle θ is proportional to the cantilever length L and the torque T. Therefore, the platform verification parameters of the existing project can be used as the calibration benchmark, and the span between the first movable connection mechanism 2 and the second movable connection mechanism 3 and the self-gravity ratio of the pedal panel 1 can be used as the coefficient relationship to achieve platform compensation design.

[0114] For example, the torsion angle θ1 of the electric foot pedal applied to vehicle type A can be first obtained through experiments, and the span L1 between the first movable connecting mechanism 2 and the second movable connecting mechanism 3 in the electric foot pedal and the gravity T1 of the pedal panel 1 can be recorded. When designing the electric foot pedal applied to vehicle type B, the span L2 between the first movable connecting mechanism 2 and the second movable connecting mechanism 3 in the electric foot pedal applied to vehicle type B and the gravity T2 of the pedal panel 1 can be first measured, and then the torsion angle θ2 of the electric foot pedal applied to vehicle type B can be calculated with the help of the formula θ1=T1×L1 / θ2=T2×L2. Finally, according to the torsion angle θ2, the span L2 between the first movable connecting mechanism 2 and the second movable connecting mechanism 3, and the distance between the first connecting surface 2111 and the second connecting surface 3111 (measured with a measuring ruler), the trigonometric function formula is used to calculate the falling amount of the electric foot pedal applied to vehicle type B before compensation design is performed, and compensation design is performed based on the falling amount.
