Description

Technical Field

[0001] This utility model relates to the field of large vehicle retarders, specifically to an intelligent control device for a large vehicle retarder. Background Technology

[0002] A car retarder works by energizing the excitation coil of the rotor assembly through a control circuit, generating a magnetic field. The rotor assembly rotates at high speed along with the vehicle's transmission, cutting magnetic lines of force and generating a reverse torque to slow down the vehicle. The retarder switches used in cars today are mechanical direct-pull switches, and the retarder must be manually operated by the driver. The driver must constantly consider the working status of the retarder while driving, which can distract the driver.

[0003] Existing car retarders require manual control to open and close, which is not intelligent enough. In case of emergencies, there is a possibility of forgetting to turn off the retarder. In this case, pressing the accelerator will accelerate the wear of the retarder and cause it to burn out, which is very dangerous. Therefore, to address the above problems, an intelligent control device for large car retarders is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent control device for a large automobile retarder to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A smart control device for a large automotive retarder includes an accelerator pedal. A limit groove is formed on one side of the accelerator pedal, and a connecting rod is engaged with the inside of the limit groove. A fixed housing is provided on the outer side of the accelerator pedal, and first sliding grooves are formed on both sides of the inner side of the fixed housing. A support rod is fixedly connected to the outer side of the accelerator pedal, and a support shell is fixedly connected to the inner side of the fixed housing. A second sliding groove, symmetrically arranged, is formed at one end of the support shell. A limit block is engaged with the inner side of the second sliding groove, and a pressing plate is fixedly connected to the inner side of the limit block. A retarder switch located inside the support shell is fixedly connected to the inner side of the fixed housing. A spring is fixedly connected between the retarder switch and the pressing plate. A pressing rod located inside the spring is fixedly connected to the inner side of the pressing plate. A trigger rod is fixedly connected to the end of the support rod away from the fixed housing, and a first magnetic ring located outside the trigger rod is fixedly connected to the end of the support rod away from the accelerator pedal.

[0006] Preferably, a rubber sleeve is engaged with the outer side of the trigger rod, a second magnet ring is fixedly connected to one side of the rubber sleeve, a first magnet ring is fixedly connected to the outer side of the pressing rod, and a fixing bolt is engaged with the inner sides of the first and second magnet rings.

[0007] Preferably, there are two limiting blocks, which are symmetrically arranged inside the second groove.

[0008] Preferably, the first magnet ring and the second magnet ring have the same shape, and the second magnet ring is magnetically connected to one side of the first magnet ring.

[0009] Preferably, the inner diameter of the rubber sleeve is the same as the outer diameter of the trigger rod, and the length of the rubber sleeve is the same as the length of the trigger rod.

[0010] Preferably, a connecting rod is engaged with the inner side of the first slide groove, and the outer diameter of the connecting rod is the same as the inner diameter of the first slide groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, through the components such as an accelerator pedal, a limiting groove, a fixing groove, a first sliding groove, a connecting rod, a support shell, a second sliding groove, a pressing plate, a retarder switch, a pressing rod, a spring, a support rod, and a trigger rod, when the accelerator pedal is first pressed, it moves under the limitation of the first sliding groove and the limiting block. Simultaneously, the accelerator pedal moves, driving the support rod to move. The support rod then drives the trigger rod to move, pressing the pressing plate. The pressing plate moves under the limitation of the limiting block and the first sliding groove, driving the pressing rod to move. Pressing the lever activates the retarder switch. When the retarder switch is pressed, the buffer is closed, allowing the vehicle to drive normally. When the accelerator is released, the trigger lever, under the action of a spring, will move away from the press plate. The press plate will then cause the lever to stop pressing the retarder switch, and the retarder switch will control the buffer to decelerate normally, preventing the vehicle from going too fast. This solves the problem that existing car retarders require manual control to open and close, which is not intelligent enough. In case of emergencies, there is a possibility of forgetting to close the retarder. In this case, pressing the accelerator will accelerate the wear of the retarder, causing it to burn out, which is extremely dangerous. 2. In this utility model, the rubber sleeve, fixing bolt, first magnet ring, and second magnet ring are designed to effectively protect the trigger rod from wear. After a period of use, the fixing bolt can be pulled upwards to separate the first and second magnet rings. After separating the second magnet ring, the rubber sleeve and trigger rod are separated by the second magnet ring. A new rubber sleeve is then placed on the surface of the trigger rod, and the first and second magnet rings attract and fix the rubber sleeve to the surface of the trigger rod. After fixing, the fixing bolt is passed through the first and second magnet rings to fix them together, preventing the rubber sleeve and trigger rod from separating. This achieves the effect of protecting the trigger rod, thus solving the problem of wear caused by the trigger rod's frequent contact with the pressing plate, and also facilitates the replacement of the protective sleeve.
