At the same time, the connecting rod mechanism can also realize the unloading effect, that is, reduce or eliminate the force or torque applied to the mechanism by the outside. Specifically, by reasonably designing the structure and connection method of the connecting rod mechanism, a part of the externally applied force or torque can be transmitted to other parts, thereby reducing the force or torque borne by certain connection points or components, realizing the unloading effect, and thus improving the reliability and performance of the mechanism.

[0063] In one embodiment, referring to Figure 1 The pedal assembly includes two connecting rod mechanisms, which are arranged on the driving mechanism 8 at an interval, and the two connecting rod mechanisms are connected to the pedal body 7.

[0064] As an example, the pedal assembly includes two connecting rod mechanisms, which are arranged at intervals on the driving mechanism 8, and the two connecting rod mechanisms are connected to the pedal body 7. In this way, the driving mechanism 8 can simultaneously drive the two connecting rod mechanisms to move, so as to control the movement of the pedal body 7, so as to facilitate the rapid adjustment of the pedal body 7 to the state that people want to achieve, and meet people's use needs. The two connecting rod mechanisms work simultaneously, which can make the movement of the entire pedal body 7 safer and more stable, and ensure safety in use.

[0065] In one embodiment, referring to Figure 3 and Figure 4 The driving mechanism 8 includes a driving shaft 81 and a driving motor 82. The driving shaft 81 is fixedly connected to the first end of the first connecting rod 2 of the connecting rod mechanism; the driving motor 82 is connected to the driving shaft 81 for controlling the rotation of the driving shaft 81.

[0066] As an example, the driving mechanism 8 includes a driving shaft 81 and a driving motor 82. The driving shaft 81 is fixedly connected to the first end of the first connecting rod 2 of the connecting rod mechanism; the driving motor 82 is connected to the driving shaft 81 and is used to control the rotation of the driving shaft 81. When in use, the driving motor 82 is rotated forward or reversely to drive the driving shaft 81 to rotate clockwise or counterclockwise, so as to adjust the rotation angle of the pedal body 7 through the connecting rod mechanism, so that the movement of the pedal body 7 is more intelligent and precise.

[0067] The utility model embodiment provides a car, referring to Figure 1-7 , including a pedal assembly and an instrument assembly 9; one end of the connecting rod mechanism of the pedal assembly is installed on the instrument assembly 9, and the other end of the connecting rod mechanism of the pedal assembly is connected to the pedal body 7 of the pedal assembly.

[0068] As an example, a car includes a pedal assembly and an instrument assembly 9; the pedal assembly includes a pedal body 7, a driving mechanism 8 and a connecting rod mechanism; the connecting rod mechanism includes a support seat 1, a first connecting rod 2, a second connecting rod 3, a third connecting rod 4 and a fourth connecting rod 5; during installation, the support seat 1 is used as a reference to play a supporting role; the first end of the first connecting rod 2 is rotatably connected to the first mounting position of the support seat 1, and the second end of the first connecting rod 2 is connected to the first position of the pedal body 7; the first end of the second connecting rod 3 is rotatably connected to the second mounting position of the support seat 1, and the second end of the second connecting rod 3 is connected to the pedal body The pedal body 7 is placed on the second position of the pedal body 7; the first end of the third connecting rod 4 is rotatably connected to the third mounting position of the support seat 1, the second end of the third connecting rod 4 is rotatably connected to the first end of the fourth connecting rod 5, the second end of the fourth connecting rod 5 is connected to the first connecting rod 2 or the second connecting rod 3, and the third mounting position is set between the first mounting position and the second mounting position; in this way, the first connecting rod 2 and the second connecting rod 3 are arranged between the support seat 1 and the pedal body 7 to form a rectangular movable frame, and then the third connecting rod 4 and the fourth connecting rod 5 are arranged on the support seat 1 and the first connecting rod 2 or the second connecting rod 3 to form a multi-link mechanism. When the second end of the fourth connecting rod 5 is connected to the first connecting rod 2, the third connecting rod 4 is driven to rotate, and the first connecting rod 2 can be driven to move through the fourth connecting rod 5, and the second connecting rod 3 is a connecting rod and moves with it, so that the position of the pedal body 7 can be adjusted. When the second end of the fourth connecting rod 5 is connected to the second connecting rod 3, the third connecting rod 4 is driven to rotate, and the second connecting rod 3 can be driven to move through the fourth connecting rod 5, and the first connecting rod 2 is a connecting rod and moves with it, so that the position of the pedal body 7 can be adjusted. In this example, the first connecting rod 2, the second connecting rod 3, the third connecting rod 4 and the fourth connecting rod 5 cooperate with each other to form a multi-link mechanism between the support seat 1 and the pedal body 7, which is convenient for adjusting the position of the pedal body 7 to meet people's use needs. In this example, the third mounting position is set between the first mounting position and the second mounting position; when the third mounting position is set at a side position close to the first mounting position, the second end of the fourth connecting rod 5 is connected to the second connecting rod 3; when the third mounting position is set at a side position close to the second mounting position, the second end of the fourth connecting rod 5 can be connected to the first connecting rod 2.

[0069] In this example, the connecting rod mechanism is applied to the pedal assembly, and the connecting rod mechanism is connected to the driving mechanism 8 and the pedal body 7 respectively; the driving mechanism 8 drives the connecting rod mechanism to move to control the movement of the pedal body 7; the design of the connecting rod mechanism can adjust the angle and height of the pedal body 7 according to the sitting posture, so that the pedal body is very smooth and natural when it is folded, and it is integrated with the entire interior design, so as to avoid the position of the pedal body 7 being relatively low relative to the sitting posture of the human body, and ensure that the pedal assembly can provide a good support for the driver. In the connecting rod mechanism, due to the connection relationship between the various connecting rods, when external force or torque is applied, these forces and torques will be transmitted and converted between the connecting rods, thereby realizing the required mechanical movement. At the same time, the connecting rod mechanism can also realize the unloading effect, that is, reduce or eliminate the external force or torque applied to the mechanism. Specifically, by reasonably designing the structure and connection method of the connecting rod mechanism, a part of the externally applied force or torque can be transmitted to other parts, thereby reducing the force or torque borne by certain connection points or components, realizing the unloading effect, and thus improving the reliability and performance of the mechanism. One end of the connecting rod mechanism of the pedal assembly is mounted on the instrument assembly 9, and the other end of the connecting rod mechanism of the pedal assembly is connected to the pedal body 7 of the pedal assembly.

[0070] In this example, the pedal body 7 of the pedal assembly is completely folded when not in use, which does not affect the design style of the interior instrument assembly 9 and can be well integrated with the instrument assembly 9 in the car interior. When the footrest is needed, the motor is driven and a multi-link mechanism is used to unfold the footrest. The unfolding height and angle can be set according to different sitting postures to ensure the best lying comfort; when folded, it is integrated with the instrument assembly 9, and when opened, it provides good support for the occupant's feet.

[0071] In one embodiment, referring to Figure 7 The instrument assembly 9 includes an instrument panel 91 and a guard plate 92; one end of the guard plate 92 is fixed on the instrument panel 91, and the other end of the guard plate 92 extends to the bottom of the instrument panel 91; the guard plate 92 cooperates with the instrument panel 91 to form an activity space; the pedal assembly is located in the activity space.

[0072] As an example, the interior design of new energy vehicles is becoming more and more technological and simplified. The design of the instrument panel 91 is also more lightweight. More and more models without glove box functions are emerging. At the same time, if the co-pilot wants to be more comfortable, he will generally lower the seat and adjust it backward, and the backrest angle will be adjusted to lie flat. At this time, if the guard plate 92 on the lower side of the instrument panel 91 can be used to provide a pedal for the feet as a foot support, then even ordinary seats can experience the relaxing effect of lying flat on the whole body of the zero-gravity seat. In this embodiment, the instrument assembly 9 includes an instrument panel 91 and a guard plate 92; one end of the guard plate 92 is fixed on the instrument panel 91, and the other end of the guard plate 92 extends to the bottom of the instrument panel 91; the guard plate 92 cooperates with the instrument panel 91 to form an activity space; the pedal assembly is located in the activity space. The pedal assembly is designed as an electric foot pedal, and the pedal body 7 is installed on the lower trim of the instrument panel 91, and is automatically lowered when needed for passengers to rest. When not needed, the pedal body 7 is folded up to maintain the integrity of the interior design. Such arrangement of the pedal body 7 can not only take into account the light and technological design of the interior instrument panel 91, but also use the ingenious structural design to bring a comfortable driving experience to the passengers.
