Description

Technical Field

[0001] This utility model relates to the field of vehicle braking technology, specifically to a vehicle braking device based on a potentiometer. Background Technology

[0002] A potentiometer, also known as a variable resistor, is a rotary displacement sensor commonly used in vehicle braking systems.

[0003] During vehicle braking, the potentiometer acquires the rotation angle when the driver presses the brake pedal and uses it as an input signal to the main control terminal, which then outputs a corresponding pressure signal to the brake components to control the vehicle's wheels to brake as needed.

[0004] However, existing potentiometer-based vehicle braking systems have the following drawbacks: Firstly, while there are many types of potentiometers, the existing brake pad structure of the vehicle limits the selection of components for the braking system. This often prevents the user from arbitrarily choosing the appropriate potentiometer model to meet actual needs, resulting in braking performance that fails to meet the driver's requirements. Secondly, existing potentiometers are primarily designed with reliability in mind, requiring only accurate detection of angle signals for braking. However, they do not adequately consider the accuracy of rotation angle detection, further hindering improvements in actual braking performance. Utility Model Content

[0031] During vehicle braking, a potentiometer is used to acquire the rotational amount at the pedal, which is then processed to obtain a corresponding braking signal to brake the vehicle. However, in existing potentiometer-based vehicle braking systems, there are many different sizes and specifications of potentiometers, and their installation scenarios are not universal, making it impossible to arbitrarily select the required model of potentiometer to implement the braking system according to actual needs. Furthermore, there is also the problem of inaccurate detection of rotation angle. Therefore, this embodiment aims to provide a potentiometer-based vehicle braking device to improve the above-mentioned technical deficiencies.

[0032] The vehicle braking device based on a potentiometer disclosed in this utility model will be further described in detail below with reference to the embodiments shown in the accompanying drawings.

[0033] Combination Figures 1-2 As shown, the braking device includes a pedal housing 1, a potentiometer housing 2, and a potentiometer that cooperate with each other. Specifically, the pedal housing 1 is used to house the pedal 3, and the potentiometer housing 2 is used to house the potentiometer. The pedal housing 1 and the potentiometer housing 2 cooperate with each other to realize the installation of the potentiometer.

[0034] Specifically, the pedal housing 1 has a first mounting groove 1.1, the wall of which protrudes from the outer surface of the pedal housing 1. Specifically, a protrusion is movably provided within the first mounting groove 1.1, the protrusion engaging with the pedal shaft to rotate synchronously with it. A fixing seat 12 is also included, fixedly connected to the pedal housing 1. Thus, the pedal housing 1 can be fixed to the vehicle to be installed via the fixing seat.

[0035] The potentiometer housing 2 includes a first mounting portion 2.1 and a second mounting portion 2.2. The first mounting portion 2.1 has a second mounting groove, the wall of which protrudes from the outer surface of the first mounting portion 2.1. The first mounting groove 2.1 and the second mounting groove are engaged and fitted together, and a fixing shaft is provided inside the second mounting groove.

[0036] Specifically, the potentiometer includes a main board 4, a rotating shaft 5, and a torsion spring 6 that cooperate with each other. The main board 4 is embedded in the second mounting part 2.2, and the torsion spring 6 is sleeved on the rotating shaft 5. One end of the rotating shaft 5 is movably sleeved on the fixed shaft, and the other end is movably sleeved on the pedal shaft. Specifically, a plurality of magnets 7 are embedded in the end of the rotating shaft 5 that cooperates with the pedal shaft, and a plurality of reed switches 4.1 are provided on the main board. The magnets 7 are spaced apart circumferentially, and the reed switches 4.1 are spaced apart circumferentially, with each magnet 7 corresponding to each reed switch 4.1.

[0037] In practical implementation, when selecting and installing the potentiometer, corresponding pedal housing 1 and potentiometer housing 2 are provided, along with corresponding snap-fit ​​first mounting groove 1.1 and second mounting groove. Therefore, when installing various potentiometers, simply select the appropriate potentiometer housing 2 and pedal housing 1, place the potentiometer inside the potentiometer housing 2, place the pedal 3 inside the pedal housing 1, and the snap-fit ​​between the first mounting groove 1.1 and the second mounting groove allows for the application of any type of potentiometer on any type of vehicle pedal for braking. When detecting rotation angle, multiple sets of one-to-one corresponding magnets 7 and reed switches 4.1 are arranged circumferentially. When the pedal 3 is pressed and rotated to any angle, the magnet 7 at the corresponding position triggers the reed switch 4.1 at the corresponding position, thus obtaining a rotation amount consistent with the actual rotation angle, resulting in higher detection accuracy.

[0038] To further improve detection accuracy, a filler is also included; the filler is evenly filled into all the gaps inside the potentiometer housing 2. In this case, the filler serves a sealing and shock-absorbing function, reducing measurement errors caused by vibrations during vehicle operation.

[0039] To prevent the rotating shaft 5 from falling off during installation and use, the potentiometer also includes a retaining ring 8. Specifically, the retaining ring 8 is fitted onto the rotating shaft. In this case, the retaining ring 8 will limit the rotation of the shaft 5 to prevent it from falling off.

[0040] To facilitate rapid and accurate installation of the potentiometer and its housing 2 during installation, the pedal housing 1 is provided with several limiting protrusions 1.2, each positioned circumferentially along the first mounting groove 1.1. The first mounting portion 2.1 in the potentiometer housing 2 is provided with several limiting grooves, each positioned circumferentially along the second mounting groove. The limiting protrusions 1.2 and the limiting grooves are engaged and fitted one-to-one. Therefore, during installation, simply engaging the corresponding limiting protrusions 1.2 with the limiting grooves quickly achieves the installation and fixation of the potentiometer housing 2 and the pedal housing 1.

[0041] Specifically, the potentiometer housing 2 includes a wiring port 2.3, which has a built-in terminal block. The terminal block is electrically connected to the main board 4. The main board 4 communicates with an external control terminal through the terminal block. Furthermore, the braking device also includes a junction box 9. The junction box 9 engages with the wiring port 2.3. The cable communicating with the external control terminal is placed inside the junction box 9. To prevent rainwater or other liquids from seeping in through the engagement point and causing short circuits, the braking device also includes a waterproof sleeve 10. Specifically, the waterproof sleeve 10 is fitted onto the engagement point between the wiring port 2.3 and the junction box 9 to improve the sealing of the engagement point. Similarly, a waterproof wiring sleeve 11 is also provided at the cable outlet of the junction box 9 for external cables to pass through. To meet the wiring requirements of cables of different specifications, the waterproof wiring sleeve is designed to be detachable.

[0042] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
