Description

Technical Field

[0001] This utility model relates to the field of brake technology, and in particular to a pickup truck fixing caliper brake. Background Technology

[0002] As a type of vehicle that combines cargo and passenger carrying functions, the reliability of the braking system of pickup trucks is directly related to driving safety. Currently, there are many problems with the fixed caliper brakes of pickup trucks on the market that urgently need to be solved after long-term use.

[0003] First, brake pad wear monitoring is not timely or accurate enough. Traditional pickup truck brakes mostly rely on the driver's experience to judge whether the brake pads need to be replaced, or only use simple mechanical wear limit markings to indicate this. However, this method is often lagging. When the brake pads are excessively worn, it cannot issue a warning in time, which can easily lead to a decrease in braking performance or even cause a safety accident due to brake failure, seriously threatening the lives of the driver and passengers.

[0004] Secondly, the installation and adjustment of limit switches are inconvenient. Although some existing brakes are equipped with limit switches to monitor the status of related components, the installation structure of the limit switches is not reasonably designed. Most of them adopt a fixed connection method, which not only makes the installation and disassembly process cumbersome, but also makes it difficult to flexibly adjust the position according to the actual use. As a result, the limit switches cannot be accurately triggered, affecting the reliability of monitoring. Once the limit switches fail, the repair work is also very complicated, increasing maintenance costs and time. Therefore, in view of the shortcomings of existing pickup truck fixed caliper brakes in terms of brake pad wear monitoring, limit switch installation and adjustment, and maintenance economy, there is an urgent need to develop a pickup truck fixed caliper brake that can monitor the wear status of brake pads in a timely manner, is easy to install and adjust, and has low maintenance costs. Utility Model Content

[0005] One objective of this invention is to provide a pickup truck fixed caliper brake. This invention can monitor the wear condition of the brake pads in real time and accurately through a monitoring mechanism. When the brake pads wear to a certain extent, a signal is promptly transmitted to the vehicle's infotainment system to remind the user to replace them. At the same time, the limit switch adopts a threaded connection method to facilitate installation, adjustment and maintenance. The lower housing and the upper housing are fixed with bolts to achieve a modular design, which reduces the difficulty and cost of maintenance, thereby ensuring the driving safety of pickup trucks and improving the economic efficiency of use.

[0006] A pickup truck fixing caliper brake according to an embodiment of the present utility model includes a caliper housing, brake pads, and a monitoring mechanism. Brake pads are symmetrically arranged at both ends of the inner side of the caliper housing, and the brake pads are detachably connected to the built-in piston of the caliper housing. The monitoring mechanism is embedded and installed on the upper rear side of the caliper housing. The monitoring mechanism includes a lower housing and an upper housing, which are detachably fixedly connected to form a sleeve. A movable rod is provided inside the lower housing and the upper housing. The movable rod extends from the front end of the lower housing and the upper housing and is placed on the back of the brake pad. A limit switch is detachably installed on the rear side of the lower housing and the upper housing. The retractable end of the limit switch extends into the interior of the lower housing and the upper housing.

[0007] Furthermore, a spring seat is fixedly installed at the rear end of the movable rod and inside the lower and upper housings, and a spring is sleeved on the front side of the spring seat and on the movable rod, with the front end of the spring abutting against the front end of the inner side of the lower and upper housings.

[0008] Furthermore, mounting holes are provided at the four corners of the top of the lower housing, and bolts are inserted from top to bottom at the four corners of the upper housing. The bottom of the bolts is screwed into the mounting holes, and the upper housing is fixedly connected to the lower housing by the bolts.

[0009] Furthermore, the lower housing and the rear side of the upper housing are provided with threaded holes, and the outer wall of the limit switch is provided with external threads that match the threaded holes. The limit switch is screwed into the threaded holes through the external threads.

[0010] Furthermore, an oil pipe is provided on one side of the caliper housing, which is connected to the various sets of piston oil chambers inside the caliper housing for delivering brake fluid.

[0011] Furthermore, the spring seat and the movable rod are fixed by welding. The diameter of the spring seat is larger than the outer diameter of the spring and smaller than the inner diameter of the sleeve formed by the lower shell and the upper shell.

[0012] Furthermore, a wear-resistant pad is fixedly provided at the front end of the movable rod, and the wear-resistant pad is made of nitrile rubber with a thickness of 2-5mm.

[0013] Furthermore, the bolt is an internal hexagonal head bolt, and the thread length of the bolt is not less than the wall thickness of the lower housing.

[0014] Furthermore, the retractable end of the limit switch abuts against the spring seat.

[0015] Furthermore, the rear end of the limit switch is exposed outside the sleeve structure, and a wiring terminal is provided at the rear end of the limit switch.

[0016] The beneficial effects of this utility model are: 1. In this invention, as the brake pads wear down, their thickness gradually decreases. Under the elastic force of the spring, the movable rod moves forward, always maintaining contact with the back of the brake pad. When the brake pads wear down to a certain extent, the rear end of the movable rod will trigger the retractable end of the limit switch. The limit switch transmits a signal to the vehicle's infotainment system through the terminal block at the rear end, promptly reminding the user to replace the brake pads and preventing excessive wear from affecting braking performance.

[0017] 2. In this utility model, the limit switch can be installed by rotating the external thread inside the screw hole. The threaded connection makes the installation and disassembly of the limit switch more convenient, and it is easy to adjust the position of the limit switch according to actual needs to ensure that it can be accurately triggered by the moving rod. The convenient installation also makes the maintenance work more convenient when a fault occurs.

[0018] 3. In this utility model, the lower housing and the upper housing can be fixed by bolts, making it more convenient to inspect and replace vulnerable parts such as moving rods and springs inside the monitoring mechanism. This modular design reduces the scope of component disassembly during maintenance, reduces the difficulty of maintenance, and avoids the cost waste caused by overall replacement, greatly improving the economy of later maintenance.

[0025] like Figure 1-4 As shown, this utility model discloses a pickup truck fixing caliper brake, including a caliper housing 1, brake pads 3, and a monitoring mechanism 4. The brake pads 3 are symmetrically arranged at both ends of the inner side of the caliper housing 1, and the brake pads 3 are detachably connected to the built-in piston of the caliper housing 1. The monitoring mechanism 4 is embedded and installed on the upper rear side of the caliper housing 1. The monitoring mechanism 4 includes a lower housing 41 and an upper housing 42, which are detachably fixedly connected to form a sleeve. A movable rod 43 is provided inside the lower housing 41 and the upper housing 42. The movable rod 43 extends from the front end of the lower housing 41 and the upper housing 42 and is placed on the back of the brake pads 3. A limit switch 45 is detachably installed on the rear side of the lower housing 41 and the upper housing 42, and the retractable end of the limit switch 45 extends into the lower housing 41 and the upper housing 42.

[0026] The pickup truck fixed caliper brake disclosed in this application, during braking, has a piston built into the caliper housing 1 pushing the brake pad 3 to contact the brake disc, generating friction and achieving the braking effect. As the brake pad 3 wears, its thickness gradually decreases. Under the elastic force of the spring 410, the movable rod 43 moves forward, always maintaining contact with the back of the brake pad 3. When the brake pad 3 wears to a certain extent, the rear end of the movable rod 43 triggers the retractable end of the limit switch 45. The limit switch 45 transmits a signal to the vehicle's infotainment system through the rear terminal, promptly reminding the user to replace the brake pad 3 to avoid affecting braking performance due to excessive brake pad wear.

[0027] The pickup truck fixed caliper brake described in this application, through the inclusion of a monitoring mechanism 4, can monitor the wear condition of the brake pads 3 in real time and issue timely replacement reminders to ensure driving safety. Furthermore, the detachable connection of each component facilitates future repairs and replacements, reducing maintenance costs.

[0028] As a preferred example of this application, a spring seat 49 is fixedly installed at the rear end of the movable rod 43 and inside the lower housing 41 and upper housing 42. A spring 410 is sleeved on the front side of the spring seat 49 and on the movable rod 43, with the front end of the spring 410 abutting against the front end of the inner side of the lower housing 41 and upper housing 42. The spring 410 provides a continuous forward thrust to the movable rod 43, ensuring that the movable rod 43 is always in close contact with the back of the brake pad 3, thus guaranteeing the accuracy of monitoring. When the brake pad 3 wears, the movable rod 43 moves forward under the action of the spring 410. When the brake pad 3 wears to its limit position, the movable rod 43 drives the spring seat 49 to trigger the limit switch 45.

[0029] As a preferred example of this application, the lower housing 41 has mounting holes 48 at its four top corners, and bolts 47 are inserted from top to bottom at the four corners of the upper housing 42. The bottom of the bolts 47 are screwed into the mounting holes 48, and the upper housing 42 is fixedly connected to the lower housing 41 by the bolts 47. This connection method is simple in structure, firmly connected, and facilitates the disassembly and assembly of the lower housing 41 and the upper housing 42, making it convenient to inspect and replace internal components such as the movable rod 43 and the spring 410. The bolts 47 are internal hexagonal head bolts, and the thread length of the bolts 47 is not less than the wall thickness of the lower housing 41, which ensures the reliability of the connection.

[0030] As a preferred example of this application, the lower housing 41 and the upper housing 42 are provided with threaded holes 44 through their rear sides. The outer wall of the limit switch 45 is provided with external threads 46 that match the threaded holes 44. The limit switch 45 is screwed into the threaded holes 44 through the external threads 46. The threaded connection makes the installation and removal of the limit switch 45 more convenient, and facilitates the adjustment of the position of the limit switch 45 according to actual needs, ensuring that it can be accurately triggered by the movable rod 43.

[0031] As a preferred example of this application, an oil pipe 2 is provided on one side of the caliper housing 1. The oil pipe 2 is connected to the various sets of piston oil chambers inside the caliper housing 1 and is used to deliver brake fluid. The oil pipe 2 delivers brake fluid to the piston oil chambers, pushing the piston to move and realizing the braking action of the brake pads 3. This design ensures a stable delivery of brake fluid and ensures reliable braking performance.

[0032] As a preferred example of this application, the spring seat 49 and the movable rod 43 are fixed by welding. The diameter of the spring seat 49 is larger than the outer diameter of the spring 410 and smaller than the inner diameter of the sleeve formed by the lower housing 41 and the upper housing 42. The welding method ensures the firmness of the connection between the spring seat 49 and the movable rod 43, preventing loosening during long-term use. The dimensions of the spring seat 49 are reasonably designed, effectively restricting the position of the spring 410 while ensuring its smooth movement within the sleeve.

[0033] As a preferred example of this application, a wear-resistant pad is fixedly provided at the front end of the movable rod 43, and the wear-resistant pad is made of nitrile rubber with a thickness of 2-5mm. The wear-resistant pad can reduce the wear between the movable rod 43 and the back of the brake pad 3, and extend the service life of both. At the same time, the nitrile rubber material has good elasticity and wear resistance, which can ensure that the movable rod 43 and the brake pad 3 always maintain good contact.

[0034] As a preferred example of this application, the retractable end of the limit switch 45 abuts against the spring seat 49. This arrangement allows the movable rod 43 to act directly on the retractable end of the limit switch 45 through the spring seat 49, resulting in more direct force transmission and improved sensitivity and accuracy of the limit switch 45.

[0035] As a preferred example of this application, the rear end of the limit switch 45 is exposed outside the sleeve structure, and a wiring terminal is provided at the rear end of the limit switch 45. The exposed rear end facilitates the connection of the wiring terminal to the signal line, and the wiring terminal facilitates signal transmission between the limit switch 45 and the vehicle's infotainment system, ensuring that wear signals can be transmitted in a timely manner.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
