[0018] The present utility model will be further described below with reference to the accompanying drawings:

[0019] In the paragraphs of the detailed description, the orientation nouns involved are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the drawings. Unless otherwise clearly defined and limited, terms such as "set", "installed", "connected", etc. should be understood in a broad sense. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] Such asFigure 1 and Figure 2 As shown in Figure 2 , a braking pedal with adjustable initial pedal force includes a pedal base 1. Multiple groups of first mounting holes 101 are fixedly provided on the pedal base 1. A first weight-reducing hole 103 is fixedly provided in the middle of the pedal base 1. A through hole 102 is fixedly provided at the bottom of the pedal base 1. An upper baffle 2 is fixedly connected to the upper part of the pedal base 1. A pedal bracket 3 is fixedly connected to the front of the pedal base 1. The pedal bracket 3 is fixedly connected to the bottom of the upper baffle 2. A fixing bolt 9 is fixedly provided at the front of the pedal bracket 3. A nut 8 is threadedly connected to one end of the fixing bolt 9. A bearing 6 is fixedly installed on the surface of the fixing bolt 9. A pedal arm 4 is fixedly connected to the middle of the outer wall of the bearing 6. Torsion springs 7 are provided on both sides of the outer wall of the bearing 6. One end of the torsion spring 7 cooperates with the pedal arm 4. When the driver steps on the rubber footrest 5, the pedal arm 4 rotates around the bearing 6, and the vacuum booster is pushed through a push rod to achieve vehicle braking. The torsion spring 7 pushes the pedal arm 4 in the opposite direction to give feedback to the driver.

[0021] As Figure 4 As shown in Figure 4 , the pedal bracket 3 includes a mounting flange 301 and a support plate 302. By providing the mounting flange 301, the connection strength between the pedal bracket 3 and the pedal base 1 is increased, and the contact area between the two is enlarged, making the installation of the pedal bracket 3 and the pedal base 1 more stable. Multiple groups of third mounting holes 301A are fixedly provided on the mounting flange 301. The third mounting holes 301A are fixedly connected to the first mounting holes 101 through bolts. The mounting flange 301 is fixedly connected to the front of the pedal base 1. The support plate 302 is located in front of the mounting flange 301. Multiple groups of hanging holes 302A are fixedly provided on the support plate 302. The multiple groups of hanging holes 302A are distributed in a fan shape. The other end of the torsion spring 7 cooperates with the hanging holes 302A.

[0022] One end of the torsion spring 7 is fixedly connected to the pedal arm 4, and the other end of the torsion spring 7 is fixed into the hanging hole 302A. When the torsion spring 7 cooperates with the hanging holes 302A at different positions, the initial unfolding angles of the torsion spring 7 are different, and the feedback forces exerted by the torsion spring 7 on the pedal arm 4 are also different. By providing multiple groups of hanging holes 302A, when the other end of the torsion spring 7 is buckled into the hanging holes 302A at different positions, the torsion spring 7 will bear different torques, and the initial elastic forces exerted by the torsion spring 7 on the pedal arm 4 will also change accordingly, thereby changing the feedback force received by the driver.

[0023] As Figure 3As shown, the upper baffle 2 includes a fixing part 206 and a connecting and limiting part 207. The connecting and limiting part 207 is located at the front of the fixing part 206. A rib 203 is fixedly arranged between the connecting and limiting part 207 and the fixing part 206. By arranging the rib 203, the structural strength of the upper baffle 2 is increased. An installation hole two 201 is fixedly opened at the rear of the fixing part 206. The installation hole two 201 is fixedly connected to the installation hole one 101 through a bolt. Flanges 202 are arranged on both sides of the connecting and limiting part 207. By arranging the flanges 202, the contact area between the upper baffle 2 and the pedal bracket 3 is increased, and the connection strength between the two is improved.

[0024] A weight-reducing hole two 204 is fixedly opened in the middle of the connecting and limiting part 207. By opening the weight-reducing hole two 204, the weight of the connecting and limiting part 207 is reduced, and the internal stress of the connecting and limiting part 207 is eliminated. An installation screw hole 205 is fixedly opened at the front of the connecting and limiting part 207. The limiting block is fixed to the installation screw hole 205 through a bolt to fix the initial position of the pedal arm 4. Under the elastic force of the torsion spring 7, the pedal arm 4 maintains a tendency to tilt upward. Through the limitation of the limiting block, the initial position of the pedal arm 4 is fixed. The flange 202 is fixedly connected to the inner wall of the top of the support plate 302.

[0025] As Figure 5 As shown, a rubber footrest 5 is fixedly connected to the bottom of the pedal arm 4. A connection hole 401 is fixedly opened in the middle of the pedal arm 4. The connection hole 401 is connected to the push rod through a bolt. The other end of the push rod is fixedly connected to the vacuum booster. The push rod is matched with the through hole 102, thereby avoiding interference between the push rod and the pedal base 1.

[0026] In this utility model, by arranging multiple groups of hanging holes 302A, when the other end of the torsion spring 7 is buckled into the hanging holes 302A at different positions, the torsion spring 7 will bear different torques, and the initial elastic force exerted by the torsion spring 7 on the pedal arm 4 also changes accordingly, thereby changing the feedback force received by the driver. By arranging the installation flange 301, the connection strength between the pedal bracket 3 and the pedal base 1 is increased, and the contact area between the two is increased, making the installation of the pedal bracket 3 and the pedal base 1 more stable.
