Abstract

The utility model discloses a hand throwing electric glider that can take off or launch and fly, including organism and skid, the organism has motor drive's screw, a hook-like skid that inclines backward is connected to organism front portion below, places the aircraft in level ground, and the skid lifts up the aircraft head, makes the aircraft wing be in big lift drag ratio attack angle to easily take off in the roll, its hook-like skid does and draws the hook as the rubber band, launches and fly. The technical scheme solves the problem that in the prior art, the force and the angle cannot be accurately mastered when the flying electric glider is thrown by hands of the young children. The utility model discloses a but hand throwing electric glider that running takes off or launch and fly off simple structure is reliable, is convenient for fly off to greatly increased object for appreciation nature.

Description

Hand-throwing electric glider capable of running to take off or catapulting to fly

Technical Field

The utility model relates to a model toy technical field, in particular to hand throwing electric glider that can take off by running or launch and fly off.

Background

The electric glider toy taking off by hand has the boosting of the electric propeller, the flight time is long, the gliding posture is beautiful and is deeply loved by children. But since the glider needs sufficient takeoff speed to generate sufficient lift to keep the aircraft flying. In addition, the flying attitude has important influence on the flight, if the attack angle is too large, the wings stall, and simultaneously the resistance is greatly increased, the airplane can quickly fall on the ground, and if the attack angle is too small, the wing lift force is insufficient, and the airplane can also fall on the ground. Unfortunately, the main audience for such products is the younger children who often fail to consistently develop precise forces during the process of manually throwing the airplane, resulting in a failed launch.

The remote control model airplane glider is usually provided with a wheel type undercarriage, the airplane slides and accelerates on the ground by utilizing the thrust of a propeller, so as to achieve the take-off speed, but the wheel type undercarriage has a relatively complex structure, occupies a certain weight, can cause extra aerodynamic resistance, and is not suitable for being used on a child toy airplane with small size, light weight and low cost.

Therefore, there is an urgent need to develop an electric glider toy that allows children to fly easily, while satisfying the requirements of low cost and high reliability.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a can run take off or launch the hand throwing electric glider of flying, solved among the prior art problem that the hand was thrown electric glider and is difficult to fly, make to fly speed and angle and do benefit to the aircraft and take off.

The technical scheme of the utility model is that: a hand-throwing electric glider capable of running, taking off or catapulting to fly comprises a glider body and a skid, wherein the glider body is provided with a propeller driven by an electric motor, the skid is connected to the lower portion of the front portion of the glider body, the skid protrudes out of the glider body, and the front edge of the skid inclines towards the rear portion of the glider body.

Preferably, the rear edge of the skid inclines towards the rear part of the machine body, and the part of the skid protruding out of the machine body is in a shape of a hook inclining backwards and can be used as an elastic band traction hook to eject and fly.

Preferably, the skid is positioned in front of the center of gravity of the machine body, and the skid lifts the front of the machine body upwards to enable the wing attack angle alpha of the machine body to be between 2 and 10 degrees. The lift force of the attack angle is large, the resistance is small, and the airplane can easily take off in a ground accelerating and sliding mode.

To sum up, the beneficial effects of the utility model are that: the utility model discloses a but hand throwing electric glider that rollingly runs to take off or launch and fly is simple structure reliable, can easily roll to take off or launch and fly, greatly increased object for appreciation nature.

The present invention will be described in more detail by way of examples.

Drawings

Fig. 1 is a schematic structural view of a hand-throwing electric glider capable of running taking off or ejecting flying according to the present invention;

fig. 2 is a schematic view of a skid structure of the hand-throwing electric glider capable of running taking off or ejecting flying according to the present invention;

fig. 3 is a schematic view of the hand throwing electric glider capable of taking off by running or launching in a gliding manner.

Detailed Description

The present invention will be further described with reference to the following embodiments in conjunction with the accompanying drawings. The scope of the present invention is not limited thereto.

As shown in fig. 1 to 2, it shows the utility model discloses a but hand throwing electric glider that take off or launch and fly off runs, it includes organism 1 and skid 2, organism 1 has screw 11 by electric motor drive, a skid 2 is connected to organism 1 front portion below, skid 2 protrusion is outside organism 1, skid 2's leading edge 21 inclines to organism 1 rear portion.

Preferably, the rear edge 22 of the skid 2 inclines towards the rear part of the machine body 1, and the part of the skid 2 protruding out of the machine body is in a shape of a hook inclining backwards and can be used as an elastic traction hook for ejection and flying. The rubber band ejection direction and force are visual and controllable, and children can easily master the ejection skill.

As shown in fig. 3, the skid 2 is located in the front of the center of gravity G of the aircraft body 1, when the aircraft is placed on a horizontal ground, the skid 2 lifts the front of the aircraft body 1 upward to make an included angle between the wings of the aircraft body 1 and the ground, that is, an angle of attack α of the wings (also called a roll-off angle of attack) is between 2 and 10 degrees, the lift force of the angle of attack is large and the resistance is small, when the propeller 11 rotates (the propeller is driven by a power supply, a circuit, a motor, etc., which belongs to the prior art, and is not described in detail in this embodiment) and pushes the aircraft to slide forward on the ground, the air resistance received by the propeller is small. Meanwhile, the lift coefficient of the wing at the attack angle alpha is larger, and the airplane can take off the ground when the airplane is accelerated to a smaller speed.

The utility model discloses a but hand throwing electric glider that roll take-off or launch and fly is not limited to the structure in above-mentioned embodiment, can carry out multiple variation, in a word, does not deviate from the utility model discloses all improvements in the spirit scope all fall into the utility model discloses an within range.
