Description

Repair switch multiplexing circuit and instrument, electric appliance adapter, controller and electric vehicle

Technical Field

Belong to electron technical field, concretely relates to electric motor car electrical components.

Background

For convenience of description, the present invention defines the following terms:

"appliance adapter" refers to a device for collecting electrical components in a certain area on a component, in particular, directly plugged onto its circuit board, which is called an "appliance adapter". If the circuit board of the "appliance adapter" is placed directly in the meter, this component is also called "meter";

"front switches" refer to a plurality of switches on the front of the vehicle, such as: brake handle (or foot brake plate) switch, horn switch, reversing switch, three-gear switch, cruise switch, strong gear switch, electric door lock switch, neutral gear switch, etc. Except for a special repair switch in a traditional wiring mode;

"function originally" means the traditional function before the utility model. If the cruise switch is reused as the repair switch, the original function of the repair switch is cruise. At this moment, the utility model calls the cruise switch as a repair multiplexing switch;

the 'push-to-talk' is also called as fault running, and refers to emergency running when a rotating handle (or a pedal speed regulation plate) or a brake handle (or a foot brake plate) of the electric vehicle has a fault, so that the electric vehicle cannot stop on a half way. The vehicle owner can reluctantly drive to go home or deliver goods, and repair the vehicle when the vehicle is convenient;

"repair switch" refers to the switch that operates on push-to-talk;

the electric vehicle refers to a vehicle with batteries as power, such as a four-wheel electric vehicle, an electric bus, an electric sightseeing vehicle, an electric sweeper, an electric forklift, a baby carriage, an electric bicycle, an electric moped, an electric motorcycle, an electric tricycle and the like.

When the electric vehicle handle (or foot speed regulation plate) or brake handle (or foot brake plate) is in fault, the emergency running can not stop on the half road. The vehicle owner can reluctantly drive to go home or deliver goods, and repair the vehicle when the vehicle owner is convenient. This mode of operation is referred to as "push-to-talk" and some as "failed operation".

However, when a conventional push-to-talk vehicle runs, an independent repair key is needed, a repair switch is installed on a handlebar or a front panel of the vehicle independently, then a section of lead wire is connected with a large wire through a butt plug, then the long large wire is connected with a section of lead wire through the butt plug, and finally the lead wire reaches a motor controller.

Fig. 1 is a block diagram of a conventional repair switch connection circuit.

The repair switch 3 is connected to the electrical component 1 separately.

If the front switch requires N wires, the conventional wiring circuit requires N +2 wires. The number of leads and plugs is increased.

Therefore, the conventional repair switch connection circuit has problems: one more switch, multi-section wires and a plurality of connectors, thereby increasing the cost, occupying more space and reducing the reliability.

Disclosure of Invention

The utility model aims at: one switch, a plurality of sections of conducting wires and a plurality of connectors are saved, so that the cost is reduced, the space is reduced, and the reliability is improved. The defects of the traditional special repair switch circuit are overcome.

Fig. 2 is a diagram of the repair switch multiplexing connection circuit according to the present invention, which will be described in detail below.

An electric vehicle repair switch multiplexing circuit comprising: electrical components, front switches. The electrical component is connected with the front switch. The electric appliance part comprises an electric vehicle instrument, an electric appliance adapter and a motor controller, and is a general name of 3 parts of the electric vehicle instrument, the electric appliance adapter and the motor controller. The front switch of the vehicle comprises a plurality of electric switches at the front part of the electric vehicle, and is a general name of the plurality of electric switches. One of the switches in the front of the vehicle has 2 functions, one is the original function, and the other is the function of serving as a repair switch, and the switch is called a repair multiplexing switch.

The repair multiplexing switch only serves as a repair switch function when the electric vehicle is driven by one key, so that driving safety is guaranteed, and the rest time is used as an original function. The operation mode can be that the motor is driven to rotate by pressing the repair switch, and the motor is stopped to rotate by releasing the repair switch.

The selection of the repair multiplexing switch is determined by the type of the electrical components, the layout of the front switches and the type of the electric vehicle. The horn switch, the reversing switch, the three-gear switch, the cruise switch, the power gear switch, the neutral gear switch, the P-gear switch and the like can be used as repair multiplexing switches, and the repair multiplexing switches are related to the wiring and programming of the electrical appliance components.

An electric vehicle instrument applies the electric vehicle repair switch multiplexing circuit.

An electric appliance adapter of an electric vehicle applies the electric vehicle repair switch multiplexing circuit.

An electric vehicle motor controller applies the electric vehicle repair switch multiplexing circuit.

An electric vehicle is provided with the electric vehicle instrument, or the electric vehicle electric appliance adapter, or the electric vehicle motor controller.

The utility model discloses the effect: one switch, a plurality of sections of conducting wires and a plurality of connectors are saved, so that the material cost and the labor cost are reduced, the space is reduced, and the reliability is improved.

Detailed Description

The repair switch multiplexing circuit comprises an electrical component 1 and a vehicle front switch 2.

The electrical component 1 is connected with a front switch 2. The front switches 2 include a repair multiplexing switch 3.

From fig. 2, if the total number of switches of the front switches 2 is not changed from the conventional mode, the circuit of the present invention needs only N lines in total. Compared with the conventional circuit, 2 lines are reduced. If the repair switch signal is directly transmitted to the motor controller, the utility model discloses save a lot of wires, lead wire, bayonet joint.

For the processing of the repair multiplexing switch signal, one signal line is omitted on hardware, and the electric appliance part 1 only needs to process the repair multiplexing switch signal 3 in a time-sharing mode on software. When the key is pushed, the function of the repair switch is realized, and the original function is returned to the rest time.

For the electric vehicle instrument, the low-gear switch or the cruise switch is selected as the repair multiplexing switch, and the information of the repair multiplexing switch is transmitted to the motor controller through the communication line.

For the electric appliance adapter of the electric vehicle, the low-speed switch or the cruise switch is selected as the repair multiplexing switch, and the information of the repair multiplexing switch is transmitted to the motor controller through the communication line.

For the electric vehicle motor controller, the reversing switch or the neutral switch is selected as the repair multiplexing switch in the embodiment.

The embodiments and the description above are only intended to illustrate the principle of the present invention and one of the examples, and there are variations and modifications according to this principle, which fall within the scope of the present invention.
