Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, specifically to an automotive brake pedal. Background Technology

[0002] The car brake pedal is a key operating component used by the driver to control the vehicle's braking system. It mechanically transmits braking force to slow down or stop the vehicle. In emergencies, quick and precise pedal operation is crucial to avoid collisions or reduce accident damage.

[0003] The feel (softness or hardness) of a car's brake pedal directly affects driving comfort and handling experience. Some people are used to a light press for noticeable braking force, while others require more force to trigger full braking. Traditional pedals have a fixed structure, making it difficult to adapt to the habits of different drivers, resulting in a poor driving experience. An uncomfortable driving experience can also affect safe driving, so a solution is urgently needed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1 to 4 The present invention provides a technical solution: a car brake pedal, including a positioning plate 2 detachably installed at the end of the drive arm 1101 of the pedal assembly 11, a contact pedal 1 is provided above the positioning plate 2, a plurality of elastic components arranged in a rectangular distribution are provided between the contact pedal 1 and the positioning plate 2, and an adjustment component for adjusting the distance between the contact pedal 1 and the positioning plate 2 is also provided between the contact pedal 1 and the positioning plate 2.

[0026] By adjusting the distance between the contact pedal 1 and the positioning plate 2 through the adjustment component, the degree of elastic compression of the elastic component is adjusted, thereby adjusting the pedal feel (i.e., the softness or hardness) of the car brake pedal. Therefore, when the driver presses the contact pedal 1, they will drive with a comfortable pedal feel, thus meeting the driving needs of different drivers. Furthermore, after the pedal feel is adjusted to match the softness or hardness of the contact pedal 1, the driver can focus more on force control when pressing, reducing the risk of accidentally pressing the accelerator due to distraction from "finding the pedal feel," and maximizing safe driving performance.

[0027] See Figure 4 The adjustment assembly includes a stud 6 fixed to the bottom of the contact pedal 1, an internal threaded sleeve 7 threaded onto the stud 6, and a baffle 9 fixed to the circumferential side wall of the internal threaded sleeve 7. The positioning plate 2 has an opening 202 in the middle, and the lower end of the stud 6 passes through the opening 202. The tops of the baffle 9 and the internal threaded sleeve 7 are in contact with the bottom of the positioning plate 2, that is, the baffle 9 and the internal threaded sleeve 7 provide support for the positioning plate 2.

[0028] See Figure 3 and Figure 4 Each set of elastic components includes a guide rod 3 fixed to the bottom of the contact pedal 1 and a spring 4 sleeved on the guide rod 3. The surface of the spring 4 is treated with anti-rust treatment, such as by electroplating. The surface of the positioning plate 2 is provided with a guide hole 201. The lower end of the guide rod 3 passes through the guide hole 201 and is fixedly connected to a stop block 5. The guide rod 3 and the guide hole 201 are clearance fit to reduce friction. The diameter of the stop block 5 is larger than the diameter of the guide hole 201 to prevent the guide rod 3 from completely disengaging from the guide hole 201.

[0029] The following describes the process of adjusting the feel of the contact pedal 1. Rotate the internal threaded sleeve 7 so that it moves downward on the surface of the stud 6. At this time, the spring 4 releases its elastic potential energy, pushing the contact pedal 1 upward relative to the positioning plate 2, thus increasing the distance between the contact pedal 1 and the positioning plate 2. This means that the compression stroke of the spring 4 increases. When the driver presses the contact pedal 1 in the driving position, a softer feel will be felt. When the internal threaded sleeve 7 is rotated in the opposite direction so that it moves upward along the surface of the stud 6, the distance between the contact pedal 1 and the positioning plate 2 decreases, resulting in a harder feel.

[0030] Therefore, drivers can adjust the firmness of the pedal according to their own driving habits.

[0031] When the driver presses the contact pedal 1, the contact pedal 1 moves closer to the positioning plate 2, the spring 4 is compressed, and as the pressure increases, the driving arm 1101 of the pedal assembly 11 swings through the positioning plate 2 to perform braking. The aforementioned pedal assembly 11 is a conventional automobile braking structure used to brake the wheel hub.

[0032] In addition, this device is selected to be fixed on the pedal assembly 11. The selected pedal assembly 11 is within the scope of basic industry technology, and the installation method and process are also existing technology. Therefore, those skilled in the art are familiar with all the general technical knowledge in the field.

[0033] See Figure 4 The diameter of the opening 202 is greater than the diameter of the stud 6, and the outer diameter of the internal thread sleeve 7 is greater than the diameter of the opening 202.

[0034] The opening 202 does not contact the surface of the stud 6, so no frictional resistance is generated, which helps to improve the reset operation of the contact pedal 1 under the action of the spring 4; the internal threaded sleeve 7 does not pass through the inside of the opening 202, that is, it is always located below the positioning plate 2, and plays a supporting role for the positioning plate 2.

[0035] See Figures 3 to 5 The upper surface of the contact pedal 1 has striped patterns 101, which are interwoven in a mesh structure.

[0036] The striped pattern 101 increases the friction between the sole of the shoe and the contact pedal 1, making the driver's foot more stable when pressing the contact pedal 1, preventing easy slippage, and ensuring the accuracy and reliability of braking operation. Especially during emergency braking, it allows the driver to control the contact pedal 1 more forcefully and precisely, enabling the vehicle to brake in time.

[0037] If there is moisture on the contact pedal 1 (such as water brought in by the soles of shoes on a rainy day), the striped texture 101 of the mesh structure can make it easier for water to drain or fall off, avoiding the slippery surface of the contact pedal 1 due to water or debris accumulation, which would affect the friction.

[0038] See Figure 6 The bottom of the positioning plate 2 is fixedly connected to two side support blocks 8. Each side support block 8 is fixedly installed to the drive arm 1101 by bolts 10. The side support block 8 has a positioning hole 801. The bolts 10 pass through the positioning hole 801 and are threaded into the screw hole on the surface of the drive arm 1101.

[0039] That is, a stable connection can be achieved between the positioning plate 2 and the drive arm 1101. When the device is damaged, it can be replaced separately, reducing economic costs.

[0040] See Figure 3 The lateral and longitudinal widths of the contact pedal 1 are both greater than the corresponding lateral and longitudinal widths of the positioning plate 2, and the larger area of ​​the contact pedal 1 provides a comfortable stepping contact surface.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
