Description

Wind-proof quilt frame and wind-proof quilt using same

Technical Field

The invention belongs to the field of electric vehicle riding protectors, and particularly relates to a wind-proof quilt framework and a wind-proof quilt adopting the framework.

Background

The term "electric vehicle" as used herein refers to a two-wheeled or three-wheeled vehicle powered by electricity. According to the information of the Chinese bicycle society, the number of electric vehicles in China in 2020 reaches 3 hundred million.

The wind-proof quilt is a product mainly used for resisting cold of the electric vehicle, and is wind-proof, rain-proof and heat-insulating, so that the electric vehicle is more comfortable to ride in cold seasons. In addition, a light and thin wind-proof quilt is provided, and people with arthritis on knees can be used for preventing wind from blowing to knees or preventing sun. In a word, the wind-shielding quilt can be used in all seasons.

In order to protect the legs, the lower hem of the wind-proof quilt is wider than the handlebar. When riding, the bicycle is blown by wind to flap continuously, and once the bicycle is scraped to the nearby trees and vehicles, the bicycle can be turned over by people. Traffic policemen in some areas have attempted to discourage the use of windshields. But because the cost of other means (such as electric heating riding clothes) is too high, the wind shielding is difficult to be banned.

The safety problem of the wind screen is explained by quantitative calculation.

The electric motor car on the market, keep out the wind by the size various. Referring to the usual dimensions, as shown in fig. 1, assuming that the width of the handlebar (base:Sub>A-base:Sub>A ') is 70 cm, the width of the wind screen 2 (B-B') is 80 cm, i.e., the wind screen 2 is 5 cm wider than each of the two side handlebars, note that this width only refers to the width of the lower portion of the handlebar. The part of the wind screen 2 above the handlebar is hung on the neck of a person and is basically not influenced by wind, so the width of the upper part is ignored. The height of the wind screen 2 at the lower portion of the handle bar is 80 cm. In addition, the width of the step 10 is 30 cm. And 3, an electric vehicle cushion.

Since the wind screen 2 itself is wider than the handlebar, it is easily thrown out of the handlebar. The limit is shown in figure 2 with the wind screen 2 tilted 45 degrees. In the figure, CD is the height 80 cm of the wind screen 2 and DE is the width 75 cm. Note that: since the wind screen is thrown to the right, 5 cm wider than the handlebar to the left does not affect the throw distance and is negligible, so the width is in the order of 75 cm. The horizontal span of the wind screen is then: 80 Cos 45 + 75 sin 45 = 109.6 cm, reaching a distance of 109.6-70 = 39.6 cm beyond the right handlebar.

In order to solve the problem of the fluttering of the wind-shielding quilt, the prior art CN201320784081 (omnibearing wind-shielding quilt for electric vehicle) proposes to fix the wind-shielding quilt on the legs by elastic belts. The electric vehicle, as a short-distance transportation tool, often needs to stop and walk. Many people are reluctant to use the elastic band if the elastic band is to be fastened and unfastened each time the vehicle is parked or unloaded.

In the prior art CN201420402181 (multifunctional double-sided available conjoined wind-proof quilt), an elastic tightening band is provided at the edge of the wind-proof quilt to prevent the wind-proof quilt from being lifted up. However, in practice, because the wind screen is soft, the tightening strap will only cause it to bunch up, rather than just becoming a cover that fits over the legs. Even if the wind-blocking quilt is forcibly sleeved on the legs, the edges of the wind-blocking quilt can slowly contract and slip off from the legs along with the vibration of the riding dustpan, so that the quilt can not only keep warm, but also can float along with the wind.

In the prior art, CN90206827 (motorcycle safety protection plate) proposes that a round steel framework is fixed on a motorcycle, and artificial leather and the like are covered on the framework. The idea is that a shell is added outside the motorcycle, the pressure of wind is transmitted to the motorcycle through a rigid framework, so that the framework must be firm enough to bear all wind pressure, and is heavy and heavy, and is only suitable for motorcycles with strong power.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides a wind-shielding quilt framework and a wind-shielding quilt adopting the framework. The framework is convenient to use and reliable in performance, and the existing common wind-proof quilt can be refitted by using the framework.

The invention is realized in the following way:

the framework is a rectangular steel wire frame, and two horizontal sides of the steel wire frame are longer and are curved in an arc shape. When the framework is installed on the wind screen quilt, the arc-shaped opening faces the rear of the electric vehicle. Two vertical edges of the wind-proof quilt are shorter and are respectively positioned at the left side and the right side of the wind-proof quilt. The framework supports the lower hem of the wind-proof quilt into a semicircular shape.

Preferably, the connection mode of the steel wire frame and the wind screen is at least one of the following modes: seams, clips, pins and quilt holders.

Preferably, the length of the long side of the wire frame is pi times that of the short side.

The using method of the invention is as follows: the framework (steel wire frame) is fixed on the lower hem of the wind-proof quilt in a fixing mode of at least one of the following modes: directly using a seam, a clip, a pin and a quilt fixer. Two short sides of the framework are respectively positioned at the left side and the right side of the wind-shielding quilt. Because two long sides of the framework are arc-shaped and bent, and the arc-shaped opening faces the rear of the vehicle, the wind shield can be supported into a semicircular shape, and the middle of the wind shield just accommodates the legs of a person. Fig. 3 is a plan view showing that the frame 1 supports the wind screen 2, but has a gap with the seat cushion 3, and the legs of the person can come in and go out from the gap. For clarity, the frame 1 and the wind shield 2 are drawn apart from each other, but they are close together.

The outstanding substantive features and remarkable progress of the technical scheme of the invention are mainly reflected in that:

1. the safety is improved. Due to the shaping effect of the framework, the lower hem of the wind-proof quilt shrinks inwards, the influence of wind is greatly reduced, and other objects are not easy to be scraped. Even if the wind is particularly strong and the whole wind screen is blown to one side, such as the right side, when the framework touches the left leg, the wind screen is prevented from being continuously deviated. Please see the quantitative analysis of fig. 4. The relevant dimensions remain unchanged from fig. 1, so that the wind shield is moved by the framework to a width of 80/pi x 2 = 50.9 cm, i.e. the length of DE in fig. 4. When wind blows the framework to the right, the framework does not move after contacting the legs of the person, namely D in the drawing stays at the side face F of the pedal 10 and does not move to the right. At this time, E is only 0.9 cm protruded from the right handle bar, which is much safer than FIG. 1.

2. Is light and convenient. Compared with the prior art CN90206827 (motorcycle safety protection plate), the framework only supports a small area of the wind-shielding quilt downswing, and is hidden behind the front wheel, and the wind pressure blowing from the front side is not large. In addition, the framework of the wind-proof quilt is hung on the wind-proof quilt and shakes along with the wind, so that part of wind pressure is dissolved; the framework and the wind shield are directly attached to the legs of a person in strong wind, and part of wind pressure is born by the legs of the person. Combining the above factors, no need of very thick steel wire. According to the type of the wind-proof quilt, the diameter of the steel wire is only between 0.5 and 7 millimeters, so the invention has the advantage of portability.

3. The volume is small after folding, and the logistics storage cost is low. Due to the fact that social preservation quantity of the wind-proof quilt is large, a plurality of people hope to only buy the framework to modify the existing wind-proof quilt. The folding back of this skeleton is small, and is resistant to fall withstand voltage, and logistics storage's is with low costs, the facilitate promotion. The folding method is illustrated in fig. 5, 6 and 7. First, the long side of the wire frame is pushed to the opposite side as shown by the arrow in fig. 5. And turning over the steel wire intersection as shown by an arrow in fig. 6 to form a circular ring shape in fig. 7. Taking the data in fig. 1 as an example, the long side of the wire frame is 80 cm, and the long side is pi-th of the wire frame, namely 25.5 cm, so that after being folded, the wire frame becomes a flat ring with the diameter of 25.5 cm.

4. Is convenient to use. As shown in figure 3, when a user gets on or off the vehicle, the legs get in or out of the wind screen through gaps, no extra action is needed, and the method is particularly suitable for a stop-and-go scene. Because the steel wire is elastic, the leg can forcibly jack the wind-shielding quilt in and out under emergency, and the safety is ensured.

5. Simple process and low manufacturing cost. The steel wire frame is made by bending a steel wire and connecting the openings. If the joint is to undergo deformation, only expensive joining processes can be used. The deformation of the invention is generated on the long side of the framework and the short side is not deformed no matter the invention is used or folded at ordinary times. Thus, the steel wire connection points can be arranged on the short edges, and processes which cannot bear deformation, such as welding, sleeve insertion, wire locking devices and cold-pressed aluminum sleeves, can be selected, and are simple and cheap.
