Description

Technical Field

[0001] The utility model relates to the technical field of tricycles, in particular to an overload alarm for tricycles. Background Art

[0002] A tricycle is a means of transportation modified from a bicycle. It can carry people as well as goods. It is very popular and has gradually replaced the rickshaw. Existing cars do not have overload alarm devices. Whether a car, especially a truck, is overloaded is generally determined by the driver's experience. Therefore, it is easy to be overloaded, and safety accidents may occur when the vehicle is overloaded.

[0003] Among the publicly authorized patents, in the Chinese patent with patent number "CN200420035423.9", a car overload alarm is disclosed; a sleeve that can slide relative to the alarm body is installed on the alarm body, a spring is installed in the alarm body, a contact is installed on the alarm body, and a contact is also installed on the sleeve at a position matching the contact. The two contacts are connected to the wire, and a power supply, an alarm device and a delay device are also connected to the wire. A boss made of elastic material is installed on the upper end of the sleeve, and a bottom layer made of elastic material is installed on the lower end of the alarm body. The utility model is fixedly installed on the rear axle of the car through the alarm body, and the utility model issues a warning when the car is overloaded.

[0004] The above-mentioned device points out that when the overload alarm is used, the overload alarm will be installed on the rear axle of the car. When the overload alarm is installed at an angle with the rear axle, when the conventional overload alarm is installed, the rear axle will generate inclined pressure on the overload alarm. Through the force conversion relationship, it is known that the oblique force will generate vertical downward and horizontal forces. Then, when the overload alarm detects whether it generates pressure on the rear axle of the car, there will be problems of inaccurate detection and misalignment of the overload alarm during installation. For this reason, we have proposed an overload alarm for tricycles. Utility Model Content
