In the figure: 1. steering wheel, 2, air-blower, 21, motor, 22, flabellum, 3, annular wind channel, 4, ventilation hole, 5, joint structure.

The specific implementation mode is as follows:

the invention is described in detail below with reference to the drawings and specific examples.

In order to facilitate understanding, the utility model provides a better structural arrangement form of car steering wheel ventilation cooling structure refers to fig. 1, including steering wheel 1, the air-blower 2 of arranging and the annular wind channel 3 of setting, ventilation hole 4 isotructure in the steering wheel.

In one embodiment, a blower 2 and an annular air duct 3 are arranged in the rim of the steering wheel 1,

and the outer contour of the steering wheel 1 is provided with a vent hole 3, the air blower 2 supplies air into the annular air duct 3, so that internal circulating air is interacted with the outside through the vent hole 3, and the effects of heat dissipation and perspiration of the palm of a driver are achieved.

In the concrete implementation, 1 or more blowers can be arranged according to the wind power requirement of the project. The structure of the blower can adopt various products on the market, and because the inner space of the steering wheel is limited, the miniature blower with matched wind power and size is selected. Referring to fig. 2, two important components of the blower are a micro motor 21 and a fan blade 22, and the micro blower assembly can be assembled by assembling and combining the motor and the fan blade.

Meanwhile, the installation position of the blower on the steering wheel should be selected and avoided being installed on the upper half part of the steering wheel, so as to avoid damage of the blower to a driver when collision occurs. In a preferred embodiment, the blower may be installed on one or both sides of the steering wheel, and one or more may be arranged according to circumstances. For a stable and easy mounting, it is preferable to arrange the mounting position at the boundary between the rim and the spoke of the steering wheel, which is reasonable in space and structure, as shown in fig. 1 and 3.

In a preferred embodiment, the connection of the blower to the rim of the steering wheel may be secured by a snap, screw or rivet connection. For example, as shown in fig. 3, a clamping structure 5 is manufactured inside the steering wheel, and the blower is assembled in a clamping mode, so that the clamping structure is convenient to install, disassemble and maintain.

Referring to fig. 1 and 4, the annular air duct in the steering wheel may be an air duct structure formed by hollowing out an outer ring from the middle when a rim of the steering wheel is processed, and the size of the annular air duct ensures that air can smoothly flow on the premise of ensuring the structural strength of the rim of the steering wheel.

In order to interact with the outside air and create a windy environment for hands, the surface of the steering wheel needs to be ventilated, and the simplest and feasible mode is to arrange a ventilation hole. Specifically, the arrangement of the vent holes has various options, and in a further preferred embodiment, small holes are processed on the outer contour of the rim of the steering wheel to serve as the vent holes, the small holes can be uniformly distributed, or the small holes can be densely arranged on the upper part or the outer side and sparsely arranged on the lower side aiming at the hand-held state, so that the strength of the outer ring of the steering wheel can be ensured, and the air can be sent to the main position of the hand-held position of a driver to a greater extent.

Of course, in view of the overall appearance of the steering wheel, it is recommended to use a fabric design on the surface of the steering wheel, and then use a cotton net structure to ensure the convection of the air inside and outside. For example, the outer contour of the rim of the steering wheel is covered with a cotton net structure.

At present, with the requirement of high quality of vehicle accessories, the surfaces of steering wheels of some middle-high-grade automobiles adopt real leather or imitation leather designs, and for the situation, small holes are needed to be used on the real leather or the imitation leather to ensure the convection of internal air and external air.

The utility model discloses in further embodiment, the control to the air-blower is realized through control switch control and the work of adjusting micro motor, and micro motor's control switch can adopt the form of physics button switch or adopt forms such as voice switch. The micro motor is connected with the controller and the power supply through related wiring harnesses, and receives a control instruction to work.

Because the steering wheel rotates slowly and does not have a high-speed rotating working condition, the design does not need to consider dynamic balance. For convenience of wiring, the related wiring harness of the micro motor can be converged to the main wiring harness (including a horn, a multifunctional key and the like) of the steering wheel, and is bound and fixed together with the main wiring harness and then extends into the instrument panel.

As a preferred design, the power supply for the micro-motor can be provided by the cockpit area controller via a wiring harness, and the control switch can also be integrated into the cockpit area controller.

Of course, after the design is adopted, the design strength of the steering wheel should meet the requirements of relevant national regulations.

It is thus clear that for reaching the built-in air-blower of steering wheel and realizing removing sweat and keeping away hot effect, carry out as above transformation with the steering wheel on current steering wheel basis: for example, a micro motor is additionally arranged according to the requirement of the project on wind power, fan blades matched with the motor, a reserved air pipe, related wire harnesses, surface small hole treatment, surface cotton net treatment and the like are arranged.

After the structural design is adopted on the steering wheel, when a driver feels that the hand holding the steering wheel sweats, the ventilation adjusting switch of the steering wheel can be turned on in a key mode or a voice recognition mode, and the blower in the steering wheel is started. The blower drives air to circularly flow along a circle of built-in air pipes of the steering wheel. In the air flowing process, convection can be generated between the small holes on the surface of the steering wheel or the cotton net and the outside, so that air flowing is generated at the palm of the hand holding the steering wheel, and the effects of cooling and removing sweat are achieved.

Furthermore, in order to adapt to target customer groups of different projects, such as the old customers needing small air volume and the young customers needing large air volume, the number of the blowers can be set to be 1 or 2-3 according to specific project calibration, and 5V voltage can be output by the cabin domain controller to reduce the air volume.

In addition, for those skilled in the art, in the design, in order to meet further refrigeration requirements and realize refrigeration by matching with the whole vehicle, the air conditioner air duct can be directly introduced for refrigeration without a built-in blower. But it is little in near steering column space, and the air conditioner tuber pipe is arranged and is required highly, and the great scheduling factor of dismouting steering wheel influence is considered, the utility model discloses an above scheme still simplest, reasonable and the scheme that still realizes most.

The utility model discloses in further embodiment, still provide an automobile steering wheel set up above on the steering wheel ventilation cooling structure, the structure is referred to fig. 1, fig. 2, fig. 3 and fig. 4, and its specific mode, structure that sets up, the effect equals the same of the explanation of above each embodiment, therefore no longer gives unnecessary details here, reaches the purpose to driver's palm heat dissipation perspire at last.
