Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Further, "plurality" or "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1 to 3, an embodiment of the throttle valve provided by the present invention will now be described. The throttle valve is applied to an automobile and comprises a throttle valve air passage 100, a valve plate 200 rotatably arranged in the throttle valve air passage 100, a deicer and an actuating mechanism 400. Wherein, valve block 200 has except that mounting structure (rotating structure) has been connected with the inner wall of throttle valve air flue 100, has the clearance between the outer fringe of valve block 200 and the inner wall of throttle valve air flue 100, and this clearance freezes very easily and leads to valve block 200 can not the free rotation, and throttle valve air flue 100 and valve block 200 are the structure in the current throttle valve, and it is no longer repeated here.

The deicer can be slidably disposed in the throttle airway 100 along the direction of gas flow in the throttle airway 100, and if the throttle airway 100 is a cylindrical pipe, the deicer can be slidably disposed in the cylindrical pipe along the axial direction of the cylindrical pipe. The ice remover can remove the frozen ice between the valve plate 200 and the throttle airway 100 by sliding in the throttle airway 100, and certainly, the ice remover can also remove the frozen ice at other positions in the throttle airway 100. After the ice between valve plate 200 and throttle valve duct 100 is removed by the ice remover, the rotation of valve plate 200 is not restricted by the ice, and the rotation in throttle valve duct 100 can be recovered. The structure of the deicer is not limited, and the structure for deicing on the deicer can extend into the gap between the valve plate 200 and the throttle air duct 100 to deice.

An actuator 400 is mounted on the vehicle body or throttle airway 100, and the actuator 400 is used to drive the deicer to slide. The actuator 400 may be electrically connected to a vehicle computer (or control system) of the vehicle, so as to receive control of the vehicle computer or be manually operated. When the deicing operation is needed, the driving computer sends an action command to the execution mechanism 400, or the execution mechanism 400 is manually operated to act, and the execution mechanism 400 drives the deicer to slide in the throttle air duct 100, so that the ice in the throttle air duct 100 (mainly the ice between the throttle air duct 100 and the valve plate 200 is removed). After the deicing operation is performed, the deicer can be driven by the actuator 400 (of course, the actuator 400 is controlled by a crane computer or manually operated) to return to the original position and leave the gap between the throttle valve duct 100 and the valve plate 200, so as to avoid the influence of the over-wind on the valve plate 200.

In the process of passing through the throttle valve provided by the embodiment of the invention, the applicant finds that when the throttle valve is frozen, the frozen ice influencing the action of the valve plate 200 is the frozen ice at the gap between the valve plate 200 and the throttle valve air duct 100, and because the gap is not large, the frozen ice is not too thick, if the ice is removed by means of blowing with hot air or melting with the heat of an engine, the time spent is long, the user experience is easily influenced, and the method of physical shoveling is quick and convenient.

Compared with the prior art, the throttle valve provided by the embodiment of the invention has the advantages that the ice remover arranged in the throttle valve air passage in a sliding manner and the execution mechanism driving the ice remover to slide are used, frozen ice between the valve plate and the throttle valve air passage is removed by the sliding of the ice remover, the valve plate can not rotate under the restriction of the frozen ice, and the fault of the throttle valve caused by freezing is avoided.

In some embodiments, referring to fig. 1 to 3, the actuator 400 is disposed outside the throttle valve duct 100 and mounted on the outer wall of the throttle valve duct 100 to avoid the excessive wind (gas flow) affecting the throttle valve duct 100.

Fig. 1 is a schematic flow chart of a throttle deicing method according to an embodiment of the present invention, and for convenience of description, only the parts related to the embodiment of the present invention are shown. The execution main body of the embodiment of the invention can be a throttle valve, the terminal equipment can be a driving computer, and the driving computer generally at least comprises a processor and a memory.

Referring to fig. 1, a throttle deicing method according to an embodiment of the present invention includes the following steps:

s100 acquires temperature information.

The temperature information may be the real-time temperature of the outside, the real-time water temperature of the engine water tank, or the specific temperature in the throttle valve air passage 100.

S200, if the temperature information is lower than or equal to the preset temperature, controlling (by the actuator 400) the deicer to perform the deicing operation, and if the temperature information is higher than the preset temperature, the actuator 400 and the deicer do not perform the deicing operation.

The preset temperature may be set according to actual requirements, for example, may be set to 0 ℃, -2 ℃, and so on. When the temperature information is lower than or equal to the preset temperature, it can be considered that the valve plate 200 and the throttle valve duct 100 may be frozen, and therefore, the deicing operation is required, and if the temperature information is higher than the preset temperature, it can be considered that the action of the valve plate 200 is not affected, and the deicing operation may not be performed.

In one embodiment, the deicing operation may be embodied by driving the deicer to move between valve flap 200 and throttle body 100, and then driving the deicer to slide back and forth between valve flap 200 and throttle body 100. The number of times that the deicer slides back and forth between the valve plate 200 and the throttle valve duct 100 can be determined according to temperature information and deicing test effects corresponding to various back and forth times at different temperatures (these operation parameters can be written into a memory program of a traveling computer in advance). Of course, it should be noted here that the number of reciprocating sliding does not necessarily relate to only temperature information, but may also relate to factors such as parking time and humidity, which can be obtained through experiments by those skilled in the art, and are not described herein again.

In one embodiment, the temperature information is an outside temperature, i.e., the temperature information is a real-time air temperature of the outside world.

In one embodiment, the preset temperature is 0 ℃ on the basis that the temperature information is the outside temperature of the vehicle. If the temperature outside the vehicle is lower than or equal to 0 ℃, it can be considered that the space between the valve plate 200 and the throttle valve air passage 100 may be frozen, and therefore, the deicing operation is required, and if the temperature outside the vehicle is higher than 0 ℃, it can be considered that the action of the valve plate 200 is not affected, and the deicing operation may not be performed.

In an embodiment, after S200 (i.e., after completing the deicing operation), the throttle deicing method provided by the embodiment of the invention may further include:

s300, the ice remover is controlled to move to one end of the valve plate 200, namely the position where the ice remover leaves the gap between the valve plate 200 and the throttle air duct 100, and returns to the original initial position when the ice removing operation is not carried out, so that the influence of the overfire air at the valve plate 200 is avoided.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
