In this regard, directional terms such as "top", "bottom", "left", "right", "upper", "lower", etc. are used with reference to the orientation of the described figures. Since the components of the embodiments can be positioned in several different orientations, the directional terms are used for purposes of illustration and are in no way limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present application. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present application is defined by the appended claims.

[0031] According to a first aspect of the present application, a button structure is proposed. Figure 1 Shows a schematic installation structure diagram of the button structure according to an embodiment of the present application. Figure 2 Shows Figure 1 To highlight the cross-sectional view of the button structure, as Figure 1 , Figure 2 As shown, the button structure includes a housing 1, a PCB board 2, and a key 3. Among them, an installation cavity 11 is vertically penetrated through the housing 1. The PCB board 2 is horizontally arranged at the lower end of the housing 1. The key 3 is made of a light-transmitting material and is installed in the installation cavity 11 in a manner that is adapted to and can be pressed down.

[0032] It should be noted that the connection manner between the PCB board 2 and the housing 1 can be a fixed connection or a snap connection, an adhesive connection, etc.; in this embodiment, the connection manner between the PCB board 2 and the housing 1 is preferably a fixed connection. And the fixed connection manner can be a screw locking fixed connection or a welding connection, etc.; in this embodiment, the fixed connection manner between the PCB board 2 and the housing 1 is preferably a screw locking fixed connection.

[0033] Figure 3 Shows Figure 2 To highlight the schematic diagram of the button structure, as Figure 3As shown in the figure, specifically, buttons 21 and light sources 22 are soldered to the part of the PCB board 2 located inside the installation cavity 11. The button 3 includes a pressing part 31, a waterproof part 32, and a triggering part 33 arranged in sequence from top to bottom. Among them, the pressing part 31 is arranged to be pressed down at the opening end of the installation cavity 11; the waterproof part 32 is made of an elastic material with a hollow interior. The upper end of the waterproof part 32 abuts tightly against the pressing part 31, and the lower end abuts tightly against the PCB board 2 circumferentially. An activity cavity 111 is also formed between the waterproof part 32 and the PCB board 2. The button 21 and the light source 22 are located inside the activity cavity 111; the triggering part 33 is movably arranged inside the activity cavity 111. The upper end of the triggering part 33 is connected to the waterproof part 32, and the lower end moves and abuts against the button 21 following the pressing state of the entire button 3.

[0034] In summary, by providing a light source 22 on the PCB board 2 that aligns with the pressing part 31, the light from the light source 22 passes through the light-transmitting triggering part 33 and waterproof part 32 and shines on the also light-transmitting pressing part 31, so that the button 3 can achieve a good light-transmitting effect; and the waterproof part 32 is made of transparent silicone, and the waterproof part 32 can prevent water droplets from falling onto the PCB board 2 through the installation cavity 11, playing a waterproof role. Thus, the button structure has both light-transmitting and waterproof functions.

[0035] In this embodiment, the light source 22 is an LED lamp bead.

[0036] It should be noted that the pressing part 31 can be made of transparent or milky translucent material, and then black paint is sprayed on its surface, and the corresponding button font is laser engraved. In this embodiment, the material used for the pressing part 31 is preferably transparent PC material. In other embodiments, the pressing part can also be made of other transparent materials with a certain hardness, which is not limited here.

[0037] In this embodiment, the waterproof part 32 is made of transparent silicone, and the two sides of the lower end of the waterproof part 32 are adhesively abutted against the PCB board 2. In other embodiments, the waterproof part can also be made of other elastic and transparent waterproof materials, which is not limited here.

[0038] In this embodiment, the triggering part 33 is also made of transparent silicone, and the triggering part 33 is integrally formed with the waterproof part 32. In other embodiments, the triggering part can also be made of other transparent materials, which is not limited here.

[0039] Continue to refer to Figure 3 , an extension part 311 is integrally formed circumferentially at the lower end of the pressing part 31, and the extension part 311 movably abuts against the cavity wall of the installation cavity 11. Since the waterproof part 32 is made of transparent silicone material, the light emitted by the light source 22 will diverge outward from the cavity wall of the installation cavity 11 through the circumferential side of the waterproof part 32. The extension part 311 can block this part of the diverging light to a certain extent, thereby reducing the light leakage phenomenon at the outer peripheral side of the pressing part 31 at the opening end of the installation cavity 11.

[0040] Continue to refer to Figure 3 , a limiting boss 112 is integrally formed on the cavity wall of the installation cavity 11, and the extension part 311 abuts against the lower end of the limiting boss 112. By providing the limiting boss 112, on the one hand, it can prevent the pressing part 31 from moving upward and disengaging from the installation cavity 11; on the other hand, the limiting boss 112 is integrally formed by the housing 1 and is made of a light-impermeable material, so that the light emitted by the light source 22 can be prevented from passing through the peripheral side of the waterproof part 32 and diverging outward from the cavity wall of the installation cavity 11, avoiding light leakage at the open end of the installation cavity 11 on the outer peripheral side of the pressing part 31.

[0041] Continue to refer to Figure 3 , the caliber of the installation cavity 11 gradually becomes larger from top to bottom. In this way, on the one hand, when pressing the button 3, the downward pressing process of the button 3 in the installation cavity 11 will be smoother, and the feel of the button 3 will be better; on the other hand, the light emitted by the light source 22 can be better focused on the pressing part 31, making the light transmission effect of the pressing part 31 better.

[0042] Continue to refer to Figure 3 , the light source 22 on the PCB board 2 is directly opposite to the pressing part 31, and the button 21 and the light source 22 are arranged in a staggered manner on the PCB board 2. By arranging the light source 22 directly opposite to the pressing part 31, the light emitted by the light source 22 can be better dispersed to the pressing part 31, making the light transmission effect of the pressing part 31 better. And although the button 21 is slightly staggered relative to the pressing part 31, since the waterproof part 32 and the triggering part 33 are integrally formed by elastic transparent silicone, it will not affect the overall pressing feel of the button 3.

[0043] Continue to refer to Figure 3 , an embedding groove 312 is formed at the bottom of the pressing part 31, and the upper end of the waterproof part 32 is embedded in the embedding groove 312. The pressing part 31 in this embodiment is made of transparent PC material. When normally demolded, shrinkage is likely to occur at the upper end of the pressing part 31. By forming the embedding groove 312 at the bottom of the pressing part 31, on the one hand, shrinkage at the upper end of the pressing part 31 can be avoided, and on the other hand, since the waterproof part 32 is embedded in the embedding groove 312, the connection between the waterproof part 32 and the pressing part 31 is closer.

[0044] In this embodiment, the waterproof part 32 is embedded and fixed in the embedding groove 312 by bonding.

[0045] Combined with reference to Figure 1 and Figure 2 , a plurality of buttons 3 are distributed on the housing 1, and anti-misoperation protrusions 12 are provided on the housing 1 between two adjacent buttons 3. Since some buttons are set too close, by providing the anti-misoperation protrusions 12, it can prevent the user from accidentally touching the adjacent button when pressing the button.

[0046] Combined with reference Figure 1 and Figure 2 The waterproof parts 32 of at least two adjacent buttons 3 are integrally connected. In this embodiment, some buttons are arranged relatively close to each other, and the waterproof parts of these buttons are integrally connected; while the waterproof parts of some buttons that are farther apart are separately provided.

[0047] The implementation principle of a key structure and a drone remote controller provided in the embodiments of the present application is as follows:

[0048] By disposing a light source 22 on the PCB 2, facing the pressing portion 31, the light source 22 shines through the light-transmitting trigger portion 33 and the waterproof portion 32 toward the equally light-transmitting pressing portion 31, thereby achieving excellent light transmission for the key 3. Furthermore, the waterproof portion 32 is made of transparent silicone, preventing water droplets from falling through the mounting cavity 11 onto the PCB 2, thus providing a waterproof effect. Thus, the key structure combines both light transmission and waterproofing. Furthermore, the structural design of the mounting cavity 11 and the positional distribution of the light source 22 enhance light transmission for the pressing portion 31. The extension 311 on the pressing portion 31 and the retaining boss 112 on the wall of the mounting cavity 11 prevent the key 3 from falling off and light leakage from the key 3. The pressing portion 31 includes a recessed groove 312, which prevents shrinkage of the upper end of the pressing portion 31 during demolding. Furthermore, the waterproof portion 32, nested within the recessed groove 312, provides a tighter connection to the pressing portion 31. The waterproof portion 32 and the trigger portion 33 are integrally formed of elastic transparent silicone, which solves the problem of feel deviation of the key 3 caused by the misalignment of the button 21.

[0049] According to the second aspect of the present application, a drone remote controller is also proposed. Figure 4 The overall structure diagram of the drone remote controller according to the embodiment of the present application is shown in FIG. Figure 4 As shown, the UAV remote controller includes the above-mentioned key structure.

[0050] It should be noted that the key structure of the first aspect described above can be applied to remote controls of unmanned aerial vehicles, unmanned vehicles, and unmanned boats, etc., without limitation here.

[0051] Obviously, those skilled in the art can make various modifications and changes to the embodiments of the present application without departing from the spirit and scope of the present application. In this way, if these modifications and changes are within the scope of the claims of the present application and their equivalents, the present application is also intended to cover these modifications and changes. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims. The simple fact that certain measures are recited in mutually different dependent claims does not indicate that the combination of these measures cannot be used to advantage. Any reference signs in the claims should not be considered as limiting the scope.
