Description

Combined charging seat for engineering machinery

Technical Field

The utility model relates to a combined charging seat for engineering machinery, and belongs to the field of engineering machinery.

Background

At present, electronic equipment such as a mobile phone and the like is widely used in daily life, and an engineering machinery driver is no exception, but the electronic equipment cannot be close to a power supply for a long time in outdoor operation, and the endurance problem of the electronic equipment is very critical, so that the installation of a combined charging seat in a cab is particularly important for charging the electronic equipment. But the interface that charges is many types now, can't reach the unity, and single USB interface has been unable to satisfy all needs of charging, utilizes the female seat of cigar lighter to expand more charge modes.

Disclosure of Invention

The technical problem to be solved by the utility model is as follows: the combined charging seat with the brand new size is provided, and the cigar lighter female seat and the USB output charging port are integrated together, so that the operation of a driver is facilitated.

In order to solve the technical problem, the technical scheme of the utility model is to provide a combined charging seat for engineering machinery, which is characterized by comprising a plug, wherein signal indicating lamps are arranged around the plug, a USB output interface and a cigar lighter female seat are arranged on the plug side by side, and connecting circuits of the plug are connected through a nylon plastic corrugated pipe.

Preferably, the USB output interface and cigarette lighter female seat outside all be equipped with the plastics visor, prevent to splash water and dust, the rear side is left the pencil and is connected with the main pencil to there is the bellows protection, avoid dragging and draw and lead to the pencil to destroy, there is convex buckle plug both sides for fix interior plaque behind the driver's cabin.

Preferably, the USB output interface is provided with two charging ports, namely, a fast charging port and a slow charging port, which are respectively 5V, 2.1A, 5V and 1A, and the circuit of the USB output interface is provided with an output short-circuit protection, an output closing, a reverse polarity protection, an overheat protection, an overcharge protection, an overload protection, an overcurrent protection and a circuit device for preventing the power of the electric equipment from burning off the circuit of the whole vehicle.

Compared with the prior charging seat, the utility model has the following beneficial effects:

1. the double USB output ports are respectively a 5V1A slow charging interface and a 5V2.1A fast charging interface, so that different requirements are met;

2. the cigarette lighter female seat outputs 24V120W, and a vehicle-mounted inverter can be configured, so that 24V direct current is converted into 220V alternating current to provide a power supply for small-power electric appliances;

3. when the voltage of the storage battery is higher than 23.5V, the blue indicator lamp around the interface is normally on to indicate that the charging seat can normally work, and when the voltage of the storage battery is lower than 23.5V, the blue indicator lamp around the interface of the charging socket is automatically turned off to indicate that the charging seat can not normally work, and the charging seat is automatically powered off, so that the service life of the storage battery can be prolonged, and the problem that the whole vehicle can not normally start due to serious power shortage of the storage battery is avoided;

4. install the interior plaque behind the driver's cabin, space utilization improves, and the size of a dimension designs more rationally.

Detailed Description

In order to make the utility model more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

As shown in the figures to 3, the combined charging seat for the engineering machinery is characterized by comprising a plug 1, signal indicating lamps are arranged around the plug 1, a USB output interface 2 and a cigarette lighter female seat 3 are arranged on the plug 1 side by side, a connecting circuit of the plug 1 is connected with the cigarette lighter female seat 3 through a nylon plastic corrugated pipe 4, plastic protective covers are arranged on the outer sides of the USB output interface 2 and the cigarette lighter female seat 3 to prevent water and dust from splashing, a wire harness is left on the rear side to be connected with a main wire harness and protected by the corrugated pipe to avoid damage of the wire harness caused by pulling, convex buckles are arranged on two sides of the plug 1 and used for fixing a rear interior trim panel of a cab, the USB output interface 2 is provided with two charging ports for quick charging and slow charging, namely 5V, 2.1A, 5V and 1A, output short-circuit protection is arranged on a circuit of the USB output interface 2, output closing, reverse polarity protection, overheat protection and overcharge protection, Overload protection, overcurrent protection and circuit devices for preventing the electric equipment from burning off the circuit of the whole vehicle due to overhigh power.

According to the utility model, two USB charging ports and a cigarette lighter female seat are integrated together, the arrangement is compact, the space is saved, the operation space is sufficiently reserved, and the plastic protective covers are arranged on the charging ports and the outer side of the cigarette lighter, so that water and dust are prevented from splashing. The rear side is provided with a wire harness connected with the main wire harness and protected by a corrugated pipe, so that the wire harness is prevented from being damaged due to pulling. Convex buckles are arranged on two sides of the charging seat and used for being fixed on a rear interior trim panel of a cab.

The USB charging port is respectively charged rapidly and slowly, and is respectively 5V2.1A and 5V 1A; the contact surface of the copper sheet at the bottom of the cigarette lighter female seat is a positive electrode, the contact surface of the copper sheet around the inner side is a negative electrode, the accessory is inserted when a charging port is expanded, and the output parameter is 24V 120W. When the two interfaces work, the blue indicator light is on, when the voltage is lower than 23.5V, the working indicator light is off, and the charging seat does not work.

As shown in fig. 4, the USB output interface and the cigar lighter socket both take electricity from a 24V power supply of the storage battery, and the input and output filter capacitors function to store energy, filter and stabilize voltage; the integrated circuit is provided with a precise comparator, and once the current is reduced, the power supply is cut off through a power supply chip so as to achieve the purpose of maintaining the voltage of the storage battery to meet the starting requirement of the whole vehicle; thermal protection, overload, overcharge and constant current diodes are used as protection mechanisms of the charging interface; the light emitting diode is lighted when the charging interface works. The integrated circuit of the cigarette lighter socket and the USB output interface are separated, voltage stabilization and amplification circuit effects are achieved, and finally a user gets electricity from the cigarette lighter socket.
