Description

A kind of automobile safety steering wheel

The invention relates to an automobile steering wheel, in particular to an automobile safety steering wheel.

In various existing automobiles, the steering wheel is rigid. When a collision occurs, the longitudinal space of the driver's cab will be compressed. cause injury to personnel. Airbags have appeared recently, but due to their complex structure and high cost, they are only installed on some high-end cars. The Chinese patent "A Safety Device for Drivers" (Application No. 97242891) discloses a device for ensuring the safety of a car driver in the event of a collision. It uses the principle of leverage to forcibly twist the steering column so that the steering wheel is far away from the driver, thereby ensuring driving personnel safety. Although this device is simple in structure, low in cost, easy to install, and reliable in performance, it will take up a certain amount of space after being installed in the driver's cab, and will have some influence on the driving operation. Steering column twisted.

The purpose of the present invention is to provide an automobile safety steering wheel which is similar to an ordinary automobile steering wheel, has simple structure, low cost, safety and reliability, and is easy to operate.

The purpose of the present invention is achieved like this:

It is composed of a disc rim (8), disc spokes (5), disc spoke covers (4) and a disc hub (7), and the disc rim (8), disc spokes (5) and disc spoke covers (4) are made of their own It is made of elastic material with high rigidity and strength, but can elastically deform when the force exceeds the rated value.

The elastic material that makes dish rim (8), dish spoke (5) and dish spoke cover (4) can be engineering rubber, also can be rubber-plastic material, can also be engineering plastics.

Inside the edge of the plate (8), two power cords (1) and (2) are provided; and on the bottom surface of the edge of the plate (8), six horn switches (14), (15), ( 16), (17), (18), (19).

A switch (12) for controlling power supply lines (1) and (2) is housed on the disc spoke cover (4).

The automobile safety steering wheel of the present invention is almost the same as the ordinary automobile steering wheel, except that the steel frame in the rim and the spokes of the disk is removed, and it is made of elastic material with relatively large rigidity and strength. Once a collision accident occurs, The cab is compressed, and the human body presses against the steering wheel. When the pressure between the human body and the steering wheel exceeds a certain value (at this time, the human body has not been injured), the disc rim, disc spokes and disc spoke covers will undergo elastic deformation, allowing Provide a certain deformation space for the human body to ensure that the driver is not hurt. Therefore, the steering wheel has the characteristics of simple structure, low cost, safety and reliability. In addition, there are evenly distributed horn switches on the bottom surface of the rim, which can ensure that the horn can still be sounded at any time when operating with both hands. Therefore, its operation is convenient.

Accompanying drawing 1 is the main sectional view of the present invention:

Accompanying drawing 2 is the top view of the present invention;

Accompanying drawing 3 is the bottom view of the present invention;

Accompanying drawing 4 is the electric schematic diagram of horn control of the present invention.

An embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

This embodiment is composed of a disc flange 8, a disc spoke 5, a disc spoke cover 4, a disc hub 7, and a control wire lead-in contact ring 6.

The rim 8 is the same as the rim of the common steering wheel, and is a circular solid body with two power cords 1 and 2 built-in; the bottom surface of the rim 8 is evenly distributed with six horn switches 14, 15, 16, 17, 18, 19 ( Also can be four to twelve), the contacts of switches 14-19 are connected with power lines 1 and 2.

The disc spokes 5 are also the same as the common steering wheel, and are distributed in two approximately symmetrical shapes (also can be three or four evenly distributed), and its two outer ends are connected with the disc edge 8 as a whole, and there are stepped through holes upwards at the outer end of the bottom surface; It wraps the disc hub 7 in the middle, and the bottom surface of this part is circular, and a control line is embedded into the contact ring 6, and several contacts 9 are evenly distributed on the lower end surface of the contact ring 6.

The disc hub 7 is made of metal and is in the shape of a sleeve. The upper end of the middle inner taper hole has a tooth-shaped spline, and its outer cylinder has a wing-shaped reinforcing rib 10.

Disc spoke cover 4 is the hollow cover shape that has reinforcing bar, and switch 12 is housed on it (also can be the same as common steering wheel, loads onto two horn switches 3 and 13 at two ends); Disc spoke cover 4 and disc spoke 5 They are connected by screws 11 mounted in the stepped through holes at the outer ends of the bottom surface of the disc spokes 5 .

Disc rim 8, disc spoke 5 and disc spoke cover 4 are made of engineering rubber (also can be made of rubber-plastic material or engineering plastics), and its force rating is determined to be 50～60 kilograms of force.

The wiring principle of the control power supply in the steering wheel is as follows: the ground wire of the horn is transmitted to the hub 7 to the spoke cover 4 through the main shaft; the control line is transmitted from the contact 9 to the contact ring 6 to the spoke cover 4; On the one hand, switch 3 and 13 are connected, on the other hand, switch 12 is connected to line 1 and line 2.

The installation and use of the automobile safety steering wheel of the present invention are the same as the ordinary steering wheel. When in use, you can press the switch 3 or 13 as usual, or press the switches 14-19 to turn on the horn; when the road section is more complicated, you need both hands to control the steering wheel. , can use switch 14～19 conveniently; When entering urban areas and forbidding to honk, switch 12 can be turned off, and can be operated as normal.

During normal driving, the rigidity and strength of the disc flange, disc spokes and disc spoke caps can meet the operating requirements. When a crash occurs, if the cab does not undergo longitudinal compression, the human body is not in danger, and the steering wheel will not be deformed; if the cab is longitudinally compressed, then pressure will be generated between the human body and the steering wheel. When the force exceeds 50 kg force, the rim of the steering wheel, the spokes and the spoke cover of the steering wheel will enter the critical state of elastic deformation. The driver is protected from injury and the purpose of safety is achieved.

The safety steering wheel for automobiles of the present invention is suitable for vehicles of different types and specifications, especially for vehicles with hydraulic transmission steering gears.
