Type freight electric vehicle controller

Currently, the principle of the cargo trikes controller circuit employed substantially the same or similar.
Brushed and brushless DC motors were powered by pulse width modulation PWM speed control method , just choose the drive difference circuits, integrated circuits , power transistor switching circuits and certain related functionality. Differences components and circuits on the same controller not constitute a performance. Controllers are two structurally, we call it separate and integral .
1 Separate : the so-called separation means separating the controller body and the display portion . The latter is mounted on the handlebar , the controller main body hidden in boxes or electric box , not outside. This approach allows the controller and power supply , shorten the distance between the motor connections , body appearance is concise.
2 -one : a control section and a display section into one, housed in a fine special plastic box. Box installed in the middle of the handlebar , there are varying amounts of open holes on the box panel , diameter 4 ~ 5mm, topical transparent waterproof membrane . Hole corresponding position with light-emitting diodes to indicate the speed , power and remaining battery power .

Tricycle canopy coating method used

In the production process of the canopy cargo trikes, the coating process is an important aspect of the method is as follows:
A doctor blade method, the fabric is coated with a spatula on a certain amount of the coating liquid, the coating thickness of the fabric by the gap between the blade and to adjust the film can be coated with different materials, both sides of the coating material .
Engraved cylinder method is a combination roller blade coating method and coating method, the coating solution on the convex surface irregularities carved drum is scraped with a scraper, a recess in the coating solution is quantitatively transferred to the fabric .
Roll method, this method can be a thick coating processing, can be more accurately adjust the coating thickness.
Lamination method, commonly used for bonding the fabric surface treatment or processing combined with hot pressing method.

Points to cargo tricycle daily cleaning glass shelf

    As we all know, driving in city streets or station next to a tricycle, after a long ride, the cargo bicycles has shed around windshield and window glass shed a lot of dirt, not only affects the appearance tricycle shed, but also on driving security had a great impact. So clean glass shed tricycle has a great need.
    This is one of the cleaning work to pay attention to some matters to be ready everyday cleaning towels, buckets, fog cleaning agents to clean some of the necessary materials. When cleaning, in strict accordance with the instructions of the cleaning agent to clean the pharmaceutical blending ratio. And check the robustness of the security glass and the like.
    To not drip with a towel dipped in the state after the start of the glass cleaner evenly coated, then scrape scrape the mirror glass of water, each must be wiped with a towel to wipe until no more water stains on glass retention.
The most important thing is to avoid scratching the glass.

How to determine if the battery is good or bad ?

Determine the battery is good or bad , we must first understand the form of battery damage , damage to the following general categories: positive plate to soften the negative plate sulfation , plate shorted circuit and so on. Can be used to judge the quality of the battery test equipment and experience of law:
First, the instrument test : general use battery discharge tester, the tester two were gripping pliers measuring positive and negative battery positive and negative electrodes , press the test button , observe the test instrument instruction situations:
1, if the instrument described above indicate voltage 9V battery in good condition.
2 , if less than 9V , but does not move the pointer is a numerical description of the state of the cargo trikes battery in a loss of electricity needed supplementary charge .
3, if the pointer is slowly declining description of the internal battery has a short circuit .
4 , the pointer quickly dropped to 0V description of the internal batteries are disconnected.
Second, the empirical method : observation battery electrolyte is muddy , muddy explanation battery positive plate to soften. Observe whether there is sediment at the bottom of the battery , if the battery capacity has been described plate off deficiencies . Hand percussion batteries have two electrodes pile If you hear a hollow sound explanation piles and poles plate fracture . With a thick wire shorted to observe the positive and negative battery post dosing each hole , as found in a compartment bubbles indicating that every corrupt.

Cargo electric vehicles Features

1, the body is small, light weight, energy in a narrow channel operations at full capacity into the elevator, and can at light load floor operations.
2, all control components are joined at the ends of the handle, simple operation, without professional driving.
3, accepted the efficiency DC traction motor, traction, speed walking step grind child can suffer heavy material handling.
4, the cargo trikes promotion system to accept corporate-style pump stations, start promotion materials can gently hold the button to start the landing button, hydraulic automatic revival, the material can slow down.
5, walking speed control selection of the latest type MOS transistor variable speed system, according to the loading of goods, the surrounding environment, casual retreat forward speed control operation. Such as the use of imported variable speed system, you can control the pace many ways, the result is better.

Introduction of electric freight cars

Electric freight car is a need for industrial applications truck driver to be charging the battery for its power source. Generally can be controlled through a computer and its route of behavior , or to set up its use of electromagnetic rail route of electromagnetic rail affixed to the floor, AGV then follow the message brought by electromagnetic rail moves and actions. cargo trikes models for the integrated layout container body , flat cargo box for the abolition of the baffle, quick and easy loading and unloading of goods , and container of ground clearance according to ergonomics program , workers do not have to bend over jobs maximize the low labor intensity of workers . Second, the minimum turning radius of 2.9m models , such as the Treasury in the narrow channel and other places can maneuver in turn, reversing . Although it looks small in size , but the container was enough to have a 2.4m long , and accepted high-strength steel plate embossed , durable, guarantee the user's needs up the goods . At run time , the car with the car deal slower, limited in plant operation by operation garden supplies , transportation tranquility are guaranteed. In addition, the car is equipped with rear traction device , handling and traction with two outcomes may expand 0.5 tons to 2 tons full range of products.

Advantages of electric tricycles

In today's society , the sales trend in the cargo bicycles gradually increased, more and more people prefer electric tricycle , whether women or elderly people can drive this car , so the electric tricycle more extensive range of applications , while occupied a very important position on the market , then the electric tricycle is what attracts people's attention advantage of it , how is the favorite to win the majority of users do ?
First, the electric tricycle is mainly used in high-quality large-capacity lead-acid batteries , using high-quality DC motor during operation , no noise generation, longer life span , and the overall structure of a simple electric tricycle , during the operation is extremely simple. Electric tricycle during operation , without causing any pollution , and help protect the environment. Electric tricycle with a reversing switch function , so that people in reversing the process, you can easily achieve reverse driving. In recent years, several major characteristics of electric tricycles to environmental protection , energy saving , comfort, economy and safety , so that more people choose electric tricycle as their travel tool , electric tricycle either in the process of moving or parking is very convenient , is the best choice for the majority of users .
