Abstract
Description
Technical Field
[0001] This invention belongs to the field of automotive technology. Specifically, this invention relates to a brake pedal assembly and a vehicle. Background Technology
[0002] Improper placement of small items such as water bottles inside a vehicle, especially near the driver's seat, can easily cause them to roll or slide off while the vehicle is in motion. When these items roll under the brake pedal, they may obstruct the pedal's travel, preventing it from being fully depressed or returning to its original position. This can affect braking performance, or even lead to brake failure, potentially causing a traffic accident.
[0003] Chinese Patent Application No. 201910415218.6 discloses a brake pedal assembly, which includes a brake pedal arm and a brake pedal mounted at the end of the brake pedal arm. It also includes a rotating connecting device and an adjusting device for adjusting the tilt angle of the brake pedal relative to a horizontal plane. The brake pedal arm has a mounting groove extending from one side to the other at its end. One end of the mounting groove is rotatably connected to the back of the brake pedal via the rotating connecting device, and the other end of the mounting groove is connected to the back of the brake pedal via the adjusting device. In use, if the user feels that the relative angle of the brake pedal surface is not suitable, they can adjust it using the adjusting device. The brake pedal will rotate via the rotating connecting device until the tilt angle of the brake pedal relative to the horizontal plane is adjusted to a suitable angle. This is equivalent to the brake pedal assembly providing a customized relative angle for the user.

[0027] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0031] This invention seriously considers the often-overlooked problem of foreign objects obstructing the brake pedal travel space in the car's passenger compartment. It discovers that while issues like water bottles blocking the brake pedal travel space are uncommon, the consequences can be exceptionally serious. Even more serious is the fact that the severity of this problem is likely to be severely overlooked and underestimated because, in the event of a collision, such evidence is almost impossible to obtain because the water bottle has already shifted during the impact, and there are often other interfering clues. Based on the principle that what is possible will inevitably happen, this invention improves the brake pedal, potentially eliminating even the most cunning culprits and improving vehicle safety.
[0032] The present invention provides a brake pedal assembly, including a brake pedal body and an enveloping sleeve, the enveloping sleeve being located between the brake pedal body and a front baffle, the front baffle being located in front of the brake pedal body.

[0037] The length of the first through hole is less than the length of the second through hole.
[0038] The front baffle includes a baffle body and an interior trim layer disposed on the baffle body, the interior trim layer being located between the brake pedal body and the baffle body.
[0039] The upper end of the brake pedal body is connected to the vacuum booster pump via a ball joint drive rod. One end of the ball joint drive rod is connected to the brake pedal body, and the other end is connected to the vacuum booster pump.
[0040] The present invention also provides a vehicle including the aforementioned brake pedal assembly.
[0041] Example
[0042] like Figures 1 to 10 As shown, this embodiment of the invention provides a brake pedal assembly, including a brake pedal body and an enveloping sleeve. The enveloping sleeve is located between the brake pedal body and a front baffle, which is located in front of the brake pedal body. The front baffle separates the vehicle's passenger compartment from the engine compartment, dividing the vehicle space into an engine compartment and a passenger compartment. The brake pedal body and the enveloping sleeve are located within the passenger compartment. By physically filling the pedal travel space with the enveloping sleeve, the problem of brake failure caused by foreign objects blocking the brake pedal travel space is solved once and for all, thus improving vehicle driving safety.
[0043] Specifically, such as Figures 1 to 10As shown, the brake pedal is a rigid structure that transmits the braking force applied by the user's foot to the main structure of the ball joint transmission rod. The upper end of the brake pedal has a bearing, allowing it to rotate around its axis; the lower end of the brake pedal has a foot pedal, facilitating force application; the brake pedal can be bent to the left to allow space between it and the accelerator pedal. The brake pedal body includes a pedal arm and a foot pedal. The upper end of the pedal arm is rotatably connected to the vehicle body, and the foot pedal is fixedly connected to the lower end of the pedal arm.
[0044] like Figures 1 to 8 As shown, the brake pedal envelope is an envelope-like body obtained by rotating the contour of the brake pedal near the sheet metal side around an axis. Aside from necessary tolerance clearances, the brake pedal envelope should theoretically be the largest possible solid—any larger and it would be unable to pass through the corresponding notches in the sheet metal and interior trim during rotation. The brake pedal envelope can be hollow or solid. By physically filling the brake pedal travel space with the brake pedal envelope, since the filled space is the brake pedal's motion envelope, it does not obstruct the brake pedal's depressing and resetting actions, but effectively solves the braking failure problem caused by foreign objects blocking the brake pedal travel space, preventing foreign objects from getting stuck on the brake pedal during braking.
[0045] like Figures 1 to 8 As shown, the enveloping sleeve includes a first filling part and a second filling part, the width of the first filling part being greater than the width of the second filling part. The first filling part is located between the foot pedal and the front fender, and the second filling part is located between the pedal arm and the front fender. The width direction of the first filling part is parallel to the width direction of the foot pedal, and the width directions of the first filling part and the foot pedal are parallel to the width direction of the vehicle body. The width direction of the second filling part is parallel to the width direction of the pedal arm, and the width directions of the second filling part and the pedal arm are parallel to the width direction of the vehicle body. The first filling part is fixedly connected to the bottom surface of the foot pedal, the second filling part is fixedly connected to the bottom surface of the foot pedal, and the lower ends of the first filling part and the second filling part are fixedly connected.
[0046] like Figures 1 to 8 As shown, a clearance hole is provided on the front baffle to allow the enveloping sheath to pass through. The clearance hole is a through hole extending along the thickness direction of the front baffle. The clearance hole includes a first through hole and a second through hole that are connected. The width of the first through hole is greater than the width of the second through hole, and the width of the first through hole is not less than the width of the first filling part. The width of the second through hole is not less than the width of the second filling part. The first through hole is located below the second through hole, and the length of the first through hole is less than the length of the second through hole. The length of the first through hole is not less than the length of the first filling part, and the length of the second through hole is not less than the length of the second filling part. When the brake pedal body is pressed, the brake pedal body drives the enveloping sheath to rotate synchronously, allowing the enveloping sheath to pass through the clearance hole, ensuring that the brake pedal body can be pressed down to achieve vehicle deceleration or stopping.
[0047] like Figures 1 to 8 As shown, the front baffle is fixedly installed and includes a baffle body and an interior trim layer disposed on the baffle body. The interior trim layer is located between the brake pedal body and the baffle body. The first through hole and the second through hole are provided through the baffle body along the thickness direction of the baffle body. The size of the clearance hole formed by the first through hole and the second through hole is based on the brake pedal envelope sleeve plus the necessary tolerance fit clearance. Theoretically, the clearance hole should be the largest possible entity—that is, if it is any larger, the brake pedal envelope sleeve will not be able to pass through the clearance hole when rotating.
[0048] like Figures 1 to 8 As shown, the interior trim layer is fixedly installed on the surface of the brake pedal body facing the brake pedal body. The design of the interior trim layer can enhance the overall visual effect of the vehicle interior, making the cockpit look more refined and high-end. By selecting appropriate materials and color combinations, the interior trim layer can coordinate with the overall style of the vehicle, creating a comfortable and pleasant driving environment. The interior trim layer can provide a certain degree of cushioning and shock absorption, reducing the impact and vibration experienced by the driver's foot when pressing the brake pedal. This helps to improve driving comfort and reduce fatigue caused by long-term driving. The first and second through holes are set through the interior trim layer along the thickness direction of the interior trim layer. The size of the clearance hole formed by the first and second through holes is based on the brake pedal envelope sleeve plus necessary tolerance clearance. Theoretically, the clearance hole on the interior trim layer should be the largest possible entity—that is, if it is any larger, the brake pedal envelope sleeve will not be able to pass through the clearance hole when rotating.
[0049] like Figure 3 and Figure 9 As shown, the upper end of the brake pedal body is connected to the vacuum booster pump via a ball joint drive rod. When the brake pedal body rotates and returns to its original position, it pushes the ball joint drive rod forward and back to its original position, respectively. The ball joint drive rod is a universal force transmission component, allowing the connected ends to transmit axial thrust and tension forces while maintaining radial displacement within limits. One end of the ball joint drive rod is connected to the brake pedal body, and the other end is connected to the vacuum booster pump, which assists in braking.
[0050] like Figure 3 and Figure 10 As shown, a vacuum booster pump can amplify the small thrust of pressing the brake pedal into a larger thrust, which then drives the hydraulic system to brake the wheels. The structure of the vacuum booster pump is as is known to those skilled in the art and will not be described in detail here.
[0051] The present invention also provides a vehicle including a brake pedal assembly with the above-described structure. The brake pedal assembly is located in the passenger compartment of the vehicle and is arranged side-by-side with the accelerator pedal assembly. The specific structure of this brake pedal assembly can be found in [reference needed]. Figures 1 to 10Further details will not be elaborated here. Since the vehicle of the present invention includes the brake pedal assembly of the above embodiments, it possesses all the advantages of the aforementioned brake pedal assembly.
[0052] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other situations without modification, are all within the protection scope of the present invention.
