Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the specific embodiments of the accompanying drawings, but the protection scope of the present invention is not limited thereto.

[0027] figure 1 , 3 Shown is a spherical connection system for a laterally stable towed caravan considering the performance of turning through, including a signal acquisition unit, an electronic control unit and an execution unit.

[0028] The signal acquisition unit is mainly composed of a steering wheel angle sensor 12 for collecting the steering wheel angle signal of the vehicle in front and sending the steering wheel angle signal to the electronic control unit.

[0029]The electronic control unit includes a caravan controller 13 and a caravan power supply 14 (12V). The caravan controller 13 uses an 80C55 single-chip microcomputer as the main body to receive the steering wheel angle signal sent by the signal acquisition unit. Whether it is in the steerin...

Abstract

The invention discloses a ball connection system of a trailer-type RV and a control method thereof. The system is composed of a signal acquisition unit, an electronic control unit and an execution unit. The signal acquisition unit is a steering wheel angle sensor, and the electronic control unit includes a RV Controller and RV power supply, the execution unit is a ball-type connection device, including a ball-type connector housing, a fulcrum support, an electromagnet bracket, a handle, a connecting ball, a clamping pressure block, a connecting rod, a spring, a lever, and an armature And the electromagnet is used to connect the front vehicle and the trailer RV, and at the same time apply or release the lateral clamping force of the ball connection device to the connection ball. When judging that the vehicle in front is turning, the execution unit releases the lateral clamping force to reduce the overall turning radius of the vehicle and improve the passing performance; when judging that the vehicle in front is not turning, the execution unit applies the lateral clamping force to ensure that the RV runs stably in a straight line without large swings. , tail flick. The invention can realize the stable running of the trailer-type RV in a straight line and the convenient steering process.

Description

technical field [0001] The present invention relates to the technical field of a towing device for a towable caravan, in particular to a spherical connection system for a towable caravan and a control method thereof. Background technique [0002] A caravan, also known as a caravan (Recreational Vehicle, RV for short), is a special mobile vehicle used for camping. The caravan is equipped with special equipment and has the functions of daily life facilities and storage. According to American RV standards, RVs are mainly divided into two types: self-propelled RVs and trailer-type RVs. [0003] Self-propelled motorhomes have an independent drive system and do not need to tow the vehicle. [0004] The towed caravan does not have an independent drive system, and needs to be connected to the towing vehicle through the towing device, and the driving force is provided by the towing vehicle. The trailer-type RV generally adopts the way of the center axle, which is different from th...
