Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

Referring to fig. 1 and fig. 2, the present embodiment provides an unmanned aerial vehicle handpiece 100, including a handpiece housing 1, where a first air inlet 1101 and a first air outlet 1102 communicated with an inner space of the handpiece housing 1 are provided on the handpiece housing 1. Through setting up first air inlet 1101 and first air outlet 1102 for inside better ventilation of realizing of aircraft nose casing 1, thereby the realization dispels the heat at the inside heating element everywhere of aircraft nose casing 1.

Wherein, first income wind gap 1101 is located aircraft nose casing 1's bottom and opening down, or said differently, first income wind gap 1101 sets up below and opening down at aircraft nose casing 1 for outside air only can enter into aircraft nose casing 1 inside by aircraft nose casing 1's below, even if so meet the condition that headwind or crosswind are great in the unmanned aerial vehicle flight process, raindrop/dust etc. also hardly enter into aircraft nose casing 1 inside through first income wind gap 1101 along from bottom to top direction, thereby effectively promote waterproof dustproof effect. First air outlet 1102 is located the tail end of aircraft nose casing 1, or, along the direction of unmanned aerial vehicle normal flight, first air outlet 1102 is located aircraft nose casing 1 one end that is close to the aircraft tail relatively, so set up and be convenient for the inside air of aircraft nose casing 1 to discharge through first air outlet 1102 smoothly, is favorable to improving the convection heat transfer effect of the inside air of aircraft nose casing 1.

Further, in order to realize that the opening of the first air inlet 1101 is disposed downward, the bottom of the handpiece housing 1 has a planar area, and the first air inlet 1 is disposed in the planar area; still further, the planar area has a recessed portion formed by recessing the bottom outer side of the handpiece housing 1 toward the bottom inner side of the handpiece housing 1, and the first air inlet 1101 is disposed in the recessed portion area. Of course, the first air inlet 1101 is disposed at the bottom of the handpiece housing 1, and due to the shielding effect of the handpiece housing 1, even if the opening of the first air inlet 1101 is not disposed downward (for example, disposed at a certain inclination angle), the first air inlet 1101 has better waterproof and dustproof effects than the first air inlet 1101 disposed at the front or the side of the handpiece housing 1.

It should be understood that, in order to achieve heat dissipation of the heat generating elements dispersed throughout the interior of handpiece housing 1, first air inlet 1101 may be provided at the bottom of handpiece housing 1 relatively close to the front end of handpiece housing 1; preferably, the first air inlet 1101 is arranged on a central axis of a handpiece shell 1 of the unmanned aerial vehicle handpiece, or two first air inlets 1101 are arranged side by side at the bottom of the handpiece shell 1, and the two first air inlets 1101 are symmetrically arranged relative to the central axis of the handpiece shell 1. Because the rear end of unmanned aerial vehicle aircraft nose generally need connect parts such as fuselage frame 15, consequently first air outlet 1102 can set up the position that is close to the lateral part relatively at the tail end of aircraft nose casing 1, or said differently, first air outlet 1102 can set up the position at the tail end of aircraft nose casing 1 skew unmanned aerial vehicle aircraft nose's axis. Of course, the first air inlet 1101 and the first air outlet 1102 may be disposed at other reasonable positions of the handpiece housing 1 according to practical situations, for example, the first air outlet 1102 is disposed at the bottom of the handpiece housing 1, and the heat convection effect inside the handpiece housing 1 can also be achieved.

Further, in order to realize that the opening of the second air inlet 1103 is disposed downward, the bottom of the head housing 1 has a planar area in which the second air inlet 1103 is disposed. The opening orientation of the second air outlet 1104 has relatively little influence on the waterproof and dustproof effects, and preferably, the opening of the second air outlet 1104 is also downward. Of course, the second air inlet 1103 is disposed at the bottom of the handpiece housing 1, and due to the shielding effect of the handpiece housing 1, even if the opening of the second air inlet 1103 is not disposed downward (for example, disposed at a certain angle), the second air inlet 1103 still has better waterproof and dustproof effects than the second air inlet 1103 disposed at the front or the side of the handpiece housing 1.

Therefore, in the embodiment of the present disclosure, the first heat dissipation assembly 3 for dissipating heat of the first functional assembly 2 is disposed in the handpiece housing 1, the first heat dissipation assembly 3 is in contact with the first functional assembly 2 in an attaching manner, preferably, the first heat dissipation assembly 3 is in contact with the first functional assembly 2 in an attaching manner, so as to transfer heat of the first functional assembly 2 to the first heat dissipation assembly 3, a heat dissipation air duct independent of an inner space of the handpiece housing 1 is formed inside the first heat dissipation assembly 3, and a second air inlet 1103 and a second air outlet 1104 communicated with the heat dissipation air duct are disposed at the bottom of the handpiece housing 1.

During the concrete implementation, in the outside air enters into the heat dissipation wind channel of first radiator unit 3 through second income wind gap 1103, takes away the heat that first radiator unit 3 was given in the transmission of first functional unit 2, then discharges the outside to aircraft nose casing 1 through second air outlet 1104, so realizes effectively dispelling the heat to first radiator unit 3, improves the radiating efficiency of first functional unit 2.

Wherein, second income wind gap 1103 and second air outlet 1104 all set up the bottom at aircraft nose casing 1, or, second income wind gap 1103 and second air outlet 1104 all set up the below at aircraft nose casing 1, make outside air enter into aircraft nose casing 1 inside from aircraft nose casing 1's below, and discharge to aircraft nose casing 1's outside from aircraft nose casing 1's below, so can effectively promote waterproof dustproof effect, reduce the risk that water droplet/dust enters into aircraft nose casing 1 inside through second income wind gap 1103 or second air outlet 1104.
