The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limitations on the utility model.

[0031] Example 1

[0032] like Figure 1 to Figure 3 As shown, this embodiment provides a clutch pedal assembly, which includes a pedal arm 1 made of nylon material; wherein the pedal arm 1 includes a body 101 and a plurality of reinforcing ribs 102 arranged on the body 101 .

[0033] The shape of the pedal arm 1 is similar to that of the metal pedal arm in the prior art, and the volume is the same. The entire material of the pedal arm 1 is made of nylon with a lower density than metal, such as PA66 nylon or POM nylon.

[0034] like Figure 2 to Figure 4As shown, in this embodiment, the pedal arm 1 includes a body 101 and a plurality of reinforcing ribs 102 disposed on the body 101; specifically, a receiving groove 103 is disposed on one side of the body 101, and all the reinforcing ribs 102 are disposed in the receiving groove 103; the plurality of reinforcing ribs 102 are connected to each other at an angle, such as an acute angle or an obtuse angle, and form a grid-like structure, and any of the reinforcing ribs 102 is connected to at least one of the groove walls of the receiving groove 103; wherein the groove wall of the receiving groove 103 includes the bottom wall and the side wall of the receiving groove 103. Preferably, the combination of the body 101, the receiving groove 103, and the plurality of reinforcing ribs 102 can be processed and integrally formed by nylon injection molding.

[0035] In the prior art, the pedal arm structure of the clutch pedal assembly adopts a rigid structure made of metal, which is heavy and does not meet the requirements of lightweight vehicle structures today; therefore, how to reduce the weight of the clutch pedal assembly is a technical problem to be solved today.

[0036] In this embodiment, on the one hand, the entire material of the pedal arm 1 is made of nylon, which reduces the overall weight of the pedal arm 1. The pedal arm is a part of the clutch pedal assembly, thereby also reducing the overall weight of the clutch pedal assembly; on the other hand, a plurality of reinforcing ribs 102 are provided on the main body 101 of the pedal arm 1, which ensure the overall strength of the pedal arm while reducing the overall weight of the pedal arm 1; therefore, this embodiment solves the technical problem of how to reduce the weight of the clutch pedal assembly in the prior art.

[0037] In actual processing, compared with the pedal arm made of material 510L, the weight of the pedal arm was reduced by 34% after changing to the pedal arm made of PA66 nylon.

[0038] Furthermore, a pedal portion 106 is provided at one end of the pedal arm 1 , and a friction protrusion is provided on the surface of the pedal portion 106 ; the provision of the friction protrusion increases the friction between the sole of the driver's foot and the pedal portion 106 .

[0039] like Figure 1 to Figure 3 As shown, further, the clutch pedal assembly also includes a bracket 5, and the pedal arm 1 is installed on the bracket 5 and can swing relative to the bracket 5; it also includes a clutch switch 4, the clutch switch 4 is connected to the bracket 5, and the shell of the clutch switch 4 is facing the side of the pedal arm 1, and a first limit surface 2 is set; the pedal arm 1 is facing the side of the clutch switch 4. The first limit portion 104 is set, and during the swinging process of the pedal arm 1, the first limit surface 2 and the first limit portion 104 can contact or separate from each other.

[0040] The structure of the clutch switch 4 is prior art and will not be elaborated here. The first limit surface 2 is arranged on the housing of the clutch switch 4; further, the clutch switch also includes a contact, and the contact can contact with the first limit portion 104; when the pedal arm 1 drives the foot pedal portion 106 to swing toward the direction of the clutch switch 4, the first limit portion 104 first contacts and squeezes the contact of the clutch switch 4, and drives the contact to retract into the housing of the clutch switch 4. After the contact is completely retracted into the housing of the clutch switch 4, the first limit surface 2 and the first limit portion 104 can contact each other; when the foot pedal portion 106 on the pedal arm 1 is stepped on by the driver and swings in the direction away from the clutch switch 4, the first limit surface 2 and the first limit portion 104 are separated from each other, and the contact is extended from the housing by the elastic member in the clutch switch 4.

[0041] In this embodiment, along the vertical direction, the pedal portion 106 on the pedal arm 1 can swing to a maximum position, which is limited by the first limiting surface 2 through the first limiting portion 104 .

[0042] Furthermore, a limiting plate 6 is provided at the bottom of the bracket 5, and a second limiting surface 3 is provided on the side of the limiting plate 6 facing the pedal arm 1; a second limiting portion 105 is provided on the side of the pedal arm 1 facing the limiting plate 6, and the second limiting surface 3 and the second limiting portion 105 can contact or separate from each other during the swinging process of the pedal arm 1. In the vertical direction, the first limiting surface 2 is located above the second limiting surface 3.

[0043] Preferably, the first limiting portion 104 and the second limiting portion 105 are integrally formed with the body 101 .

[0044] In this embodiment, along the vertical direction, the pedal portion 106 on the pedal arm 1 swings to the lowest position and is limited by the second limiting surface 3 through the second limiting portion 105 .

[0045] In this embodiment, when the first limit portion 104 contacts the first limit surface 2, it is the highest swing position of the pedal portion 106 on the pedal arm 1, and when the second limit surface 3 contacts the second limit portion 105, it is the lowest swing position of the pedal portion 106 on the pedal arm 1. This embodiment limits the highest and lowest swing positions of the pedal portion 106 on the pedal arm 1 respectively, so as to limit the upper and lower moving range of the pedal portion 106 on the pedal arm 1, and also limit the swing range of the pedal arm 1.

[0046] like Figure 1 , Figure 5As shown, further, a connection hole 107 is set in one section of the pedal arm 1; it also includes a first rotating shaft 7, and the connection hole 107 and the bracket 5 are rotatably connected through the first rotating shaft 7; it also includes a first transmission member 12, a vacuum booster 8 and a bearing assembly 9, the shell of the vacuum booster 8 is connected to the bracket 5, and the end of the pedal arm 1 away from the pedal part 106 is rotatably connected to the first transmission member 12 through the bearing assembly 9; the end of the first transmission member 12 away from the pedal arm 1 is also connected to the input end of the vacuum booster 8. Preferably, the bearing adopts a flanged bearing; preferably, the first transmission member 12 is a connecting rod.

[0047] Furthermore, the clutch pedal assembly also includes a torsion spring, one end of which is in contact with the pedal arm 1, and the other end is in contact with the bracket 5; when the driver removes the force on the pedal part 106, the pedal part 106 swings toward the direction of the clutch switch 4 through the pedal arm 1, and the power source is the torsion spring.

[0048] like Figure 1 , Figure 5 As shown, further, the clutch pedal assembly also includes a reinforcing plate 11, and the reinforcing plate 11 is connected to the bracket 5. The reinforcing plate 11 is used to be connected to the steering column of the vehicle to strengthen the strength of the steering column and reduce the vibration amplitude and abnormal sound of the steering column.

[0049] When using:

[0050] When the driver steps on the pedal portion 106 of the pedal arm 1, the pedal arm 1 is away from one end of the pedal portion 106, and the piston of the vacuum booster 8 is pushed through the first transmission member 12, so that the vacuum booster 8 establishes hydraulic pressure, and the hydraulic pressure is transmitted to the clutch slave cylinder through the pipeline and converted into a driving force to push the separation fork. At the same time, the torsion spring is compressed. When the second limit surface 3 and the second limit portion 105 contact each other, the clutch is completely separated and the gear shifting operation can be performed; in this process, the pedal arm 1 is separated from the contacts of the clutch switch 4, the clutch switch is switched, and the central controller controls the engine to reduce the speed to ensure smooth output of the gearbox without impact during gear shifting.

[0051] The driver lifts his foot to release the pedal part 106, and the torsion spring drives the pedal arm 1 back to its original position under the action of its own elastic force until the second limit surface 3 contacts the second limit part 105, and the swing position of the pedal part 106 is at the highest position. At this time, the pedal arm 1 pushes the contacts of the clutch switch 4 to retract, and the clutch switch is switched again.
