Problems solved by technology
Although the steering wheel of this structure will deform to a certain extent when it is hit by a large external force, the degree of deformation is very limited and cannot effectively reduce the damage caused by the steering wheel to the driver.
And after the steering wheel is deformed, due to the rebound effect of the spring, the steering wheel still supports the driver, and the driver cannot leave the cab due to the steering wheel

Embodiment Construction
[0019] In order to further explain the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.
[0020] Such as Figure 1 to Figure 4 As shown, the deformable and detachable safety steering wheel includes a circular coil, a disc seat 4 and a support rod 5 connected therebetween, an airbag chamber 6 is opened in the center of the disc seat, and the coil is composed of two coils connected to the support rod Rod A1, two coil rods B2 and coil rod C3 with two more segments than coil rod B (that is, four segments), the coil rod A1 is on the coil to be located in the plane where the coil is located and A straight line passing through the center of the coil is symmetrical and is respectively located between two sections of the coil rod C3, and each section of the coil rod B2 is located between the two sections of the coil rod C3;
[0021] The coil rod C3 has a central hole 15 with a square cro...

The invention discloses a deformable disassembly safety steering wheel, which comprises a circular wheel ring, a wheel seat and a supporting rod connected between the circular wheel ring and the wheel seat. An air bag chamber is arranged at the center of the wheel seat; the wheel ring consists of two sections of wheel ring rods A connected with the supporting rod, at least two sections of wheel ring rods B and wheel coil rods C, wherein the number of the wheel ring rods C is greater than that of the wheel ring rods B by two sections; the wheel ring rods A are arranged on the wheel ring and are symmetrical about a straight line, wherein the straight line is arranged in the plane of the wheel coil and passes through the center of the wheel ring, and. The wheel ring rods A are respectively positioned between two sections of wheel ring rods C; and each section of wheel ring rods B is positioned between two sections of wheel ring rods C. After subjecting to the impact of greater external force, the steering wheel can be deformed to a great extent, thus effectively reducing the harm of the steering wheel on driver and also being convenient for the driver to save oneself or help others.
Description
technical field [0001] The invention relates to a steering wheel of an automobile. Background technique [0002] The steering wheel of a car is composed of a circular coil, a disc base and a support rod. The support rod is located between the coil and the disc base to connect it as a whole. The steering wheel is connected with the steering shaft of the vehicle through the disc base to control the driving direction of the vehicle. Existing steering wheels are generally of rigid structure. When an accident occurs to the vehicle, the rigid steering wheel cannot produce geometric deformation, and thus it often causes fatal injuries to the driver. [0003] The utility model patent with the patent number ZL200620111129.0 discloses a "joint type safety steering wheel", which includes a circular coil, a disc seat and a support rod connected therebetween. The coil consists of at least three discs connected to the support rod. Coil rod A, coil rod B twice as many as coil rod A, and c...
