Description

Technical Field

[0001] This utility model relates to the technical field of alarm wiring harness devices, specifically a brake pad wear alarm wiring harness device. Background Technology

[0002] Automotive brake pads are a crucial component of the automotive braking system, playing a key role in the vehicle's deceleration and braking process. Automotive brake pads are generally composed of a steel plate, an adhesive heat insulation layer, and friction blocks. During braking, they are pressed against the brake disc or brake drum to generate friction, thereby achieving the purpose of vehicle deceleration and braking.

[0003] Currently, brake pad wear alarm harnesses on the market typically only sound an alarm when the brake pads are completely worn out. They cannot clearly indicate the specific wear condition of the brake pad friction stones, leading to delays in replacing the brake pad friction stones and resulting in a low safety factor.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model discloses a brake pad wear alarm wiring harness device, comprising a caliper body 1, hydraulic cylinders 2 on both sides of the caliper body 1, two brake plates 3 symmetrically arranged on the inner side of the caliper body 1, brake pads 4 fixedly arranged on the inner side of the brake plates 3, a drive rod connected to the brake plates 3 at the output end of the hydraulic cylinders 2, multiple fixing sleeves 11 symmetrically arranged on both sides of the caliper body 1, a button switch 13 fixedly arranged inside the fixing sleeve 11, support rods 5 penetrating the caliper body 1 at both ends of the brake plates 3, a connecting rod 6 at the outer end of the support rod 5, a fixing seat 7 at the end of the connecting rod 6 away from the support rod 5, a groove 9 on the fixing seat 7, a through hole 12 at the outer end of the fixing sleeve 11, a push rod 10 penetrating the through hole 12 and inserted into the fixing sleeve 11 in the groove 9, a screw 8 rotatably arranged on the fixing seat 7 and inserted into the push rod 10, the screw 8 being threadedly connected to the push rod 10, and an adapter cylinder 15 on one side of the fixing sleeve 11.

[0023] Basic braking process: When the driver presses the brake pedal, the hydraulic system pressure changes, and the hydraulic cylinders 2 on both sides of the caliper body 1 begin to work. The output end of the hydraulic cylinder 2 pushes the brake plate 3 through the drive rod, causing the brake pad 4 fixed inside the brake plate 3 to move closer to and fit against the brake disc, thereby generating friction and achieving vehicle braking and deceleration. During this process, due to the movement of the brake plate 3, the support rods 5 at both ends of the brake plate 3 move synchronously through the caliper body 1, and the connecting rod 6 connected to the outer end of the support rod 5 also moves accordingly, thereby driving the fixed seat 7 to move. The push rod 10 set in the groove 9 on the fixed seat 7 moves in the through hole 12 at the outer end of the fixed sleeve 11. At this time, the push rod 10 is in a position away from the button switch 13 inside the fixed sleeve 11, the button switch 13 is not triggered, and the vehicle alarm system remains silent.

[0024] Wear Detection and Alarm Process: As the vehicle's mileage increases, the brake pads 4 wear down and become thinner. During braking, as the brake pads 4 wear down, the position of the brake plate 3 gradually moves closer to the caliper body 1. The positions of the support rod 5, connecting rod 6, and mounting base 7 also change accordingly, causing the push rod 10 in the groove 9 to move closer to the button switch 13 along with the mounting base 7. When the brake pads 4 wear down to a certain extent, the bottom end of the push rod 10 presses against the button switch 13 inside the mounting sleeve 11. After the button switch 13 is triggered, its control line connects to the alarm system on the vehicle's infotainment system via the adapter 15, transmitting a signal to the alarm system. Upon receiving the signal, the alarm system activates, issuing an alarm to alert the driver that the brake pads 4 are worn.

[0025] Wear Adjustment and Monitoring Process: When it is necessary to adjust the monitoring level of brake pad 4 wear, this can be achieved by operating screw 8. For example, the actuating block in the slot at the outer end of the mounting base 7 can be used to easily rotate screw 8. The actuating block can be operated with tools such as screwdrivers. Due to the characteristics of the threaded structure, rotating screw 8 will cause push rod 10 to move axially relative to screw 8. When screw 8 rotates clockwise or counterclockwise, push rod 10 will extend or retract accordingly, thereby adjusting the distance between the bottom end of push rod 10 and push button switch 13. In addition, the scale bar on the outer wall of push rod 10 can intuitively display the position of push rod 10. Drivers or maintenance personnel can clearly understand the adjustment status of push rod 10 according to the scale bar, and thus accurately grasp the setting status of brake pad 4 wear monitoring. For example, by adjusting the position of push rod 10, it can be set that when the brake pad 4 is worn to one-half, push rod 10 presses button switch 13 to trigger the alarm system to sound an initial alarm; by adjusting the position of push rod 10 again, it can be set that when the remaining brake pad 4 is worn to one-half (i.e., one-quarter of the total thickness), the alarm system will sound an alarm again.

[0026] In this embodiment, the outer end of the fixed base 7 is provided with a slot, the outer end of the screw 8 is provided with a toggle block located inside the slot, and the outer wall of the push rod 10 is provided with a scale strip.

[0027] The slot at the outer end of the mounting base 7 and the actuating block located within the slot at the outer end of the screw 8 provide a convenient way to rotate the screw 8. Maintenance personnel or drivers can easily adjust the position of the push rod 10 by rotating the screw 8 without the need for additional complex tools. Meanwhile, the graduated strip on the outer wall of the push rod 10 further enhances the intuitiveness and accuracy of the adjustment, making the adjustment process more convenient and efficient. For example, when servicing a vehicle, maintenance personnel can quickly adjust the push rod 10 to a position suitable for the vehicle's current operating condition according to the graduated strip.

[0028] In this embodiment, the outer wall of the push rod 10 is fitted with the inner wall of the through hole 12, and sealing rings are provided on the inner wall of the adapter cylinder 15 and the inner wall of the through hole 12.

[0029] Sealing rings are provided on the inner walls of the adapter tube 15 and the through hole 12, effectively preventing external dust, moisture, and other impurities from entering the fixed sleeve 11. This avoids malfunctions of the push-button switch 13 due to impurities, ensuring the stability and reliability of the alarm function triggered by the push-button switch 13, and extending the service life of the entire alarm wiring harness. For example, when driving in rainy weather or on muddy roads, the sealing rings can effectively prevent rainwater and mud from entering the device.

[0030] In this embodiment, one end of the fixing sleeve 11 is provided with a positioning ring 14, which is fixed to the outer wall of the caliper body 1 by screws.

[0031] A positioning ring 14 at one end of the retaining sleeve 11 is fixed to the outer wall of the caliper body 1 with screws, providing accurate positioning and a convenient assembly method for the installation of the retaining sleeve 11. During production assembly or later maintenance and replacement of the retaining sleeve 11, installation can be completed quickly and accurately, improving production and maintenance efficiency. For example, on an automotive production line, workers can quickly install the retaining sleeve 11 onto the caliper body 1 using the positioning ring 14, reducing assembly time.

[0032] As part of the braking system, this brake pad 4 wear warning wiring harness device accurately monitors and warns of brake pad 4 wear. This helps drivers better understand the vehicle's braking status, rationally schedule brake pad 4 replacement times, and avoid safety hazards such as brake failure caused by excessive brake pad 4 wear. In this way, it optimizes the performance of the entire vehicle braking system and ensures safe driving.
