[0031] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0032] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0033] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0034] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0035] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0036] According to one embodiment of the present application, a protective tool is provided, which is applied to a wind vane side slip angle sensor. The protective tool comprises a protective cover 1 and a fixing unit 2, wherein the protective cover 1 has a first side wall 12 and a second side wall 13, wherein the first side wall 12 and the second side wall 13 enclose a protective space 11, wherein the protective cover 1 is arranged on the wind vane side slip angle sensor, and the wind vane 3 of the wind vane side slip angle sensor is located in the protective space 11; the fixing unit 2 is detachably arranged on the wind vane 3 of the wind vane side slip angle sensor, and the fixing unit 2 is located in the protective cover 1, and the fixing unit 2 has an open state and a closed state. The fixing unit 2 includes a positioning part 21, a rotating part 22 and a clamping part 23. The positioning part 21 and the clamping part 23 are rotatably connected through the rotating part 22. One of the positioning part 21 and the clamping part 23 is connected to the first side wall 12, and the other is connected to the second side wall 13. The positioning part 21 has a first contact surface, and the clamping part 23 has a second contact surface. A limiting groove is provided on at least one of the first contact surface and the second contact surface, and the limiting groove is adapted to the wind vane 3 of the wind vane type sideslip angle sensor.

[0037] like Figures 1 to 7 As shown in FIG, the protective tooling is used to protect the wind vane side slip angle sensor.

[0038] The protective tooling includes a protective cover 1, which can be made of waterproof and dustproof materials such as three-proof cloth. The protective cover 1 has a protective space 11 therein. The protective cover 1 is placed over the wind vane 3 of the wind vane-type sideslip angle sensor, effectively protecting the wind vane 3 from dust and water.

[0039] like Figures 1 to 4 As shown, the first side wall 12 and the second side wall 13 of the protective cover 1 have the same structure and are symmetrically arranged. The symmetry axis of the protective cover 1 is aligned with the outer wall of the rotating portion 22. When the fixing unit 2 is in the open state, the protective cover 1 is in the extended state. When the fixing unit 2 is in the closed state, the first side wall 12 and the second side wall 13 of the protective cover 1 are connected to form a protective space 11.

[0040] Connecting components such as zippers and buckles can be provided at the edges of the first side wall 12 and the second side wall 13. The zipper can connect the edges of the first side wall 12 and the second side wall 13 so that the side walls of the protective cover 1 can be closed to form a protective space 11.

[0041] Of course, in the embodiment of the present application, the first side wall 12 and the second side wall 13 are not limited to the above-described structures, and those skilled in the art may configure them according to actual needs. For example, the first side wall 12 and the second side wall 13 may have different structures, but the first side wall 12 and the second side wall 13 may be connected to form a protective space 11 that is sleeved on the weather vane 3.

[0042] The first side wall 12 can be connected to the side of the positioning portion 21 opposite the first contact surface, or to the side of the clamping portion 23 opposite the second contact surface. The second side wall 13 can be connected to the side of the positioning portion 21 opposite the first contact surface, or to the side of the clamping portion 23 opposite the second contact surface. When the first side wall 12 is connected to the positioning portion 21, the second side wall 13 is connected to the clamping portion 23. When the first side wall 12 is connected to the clamping portion 23, the second side wall 13 is connected to the positioning portion 21, so that the protective cover 1 can switch between the closed state and the open state along with the fixing unit 2.

[0043] The protective tooling also includes a fixing unit 2, which is disposed within the protective cover 1 and is connected to the fixing unit 2. The fixing unit 2 is a clamshell structure. When the fixing unit 2 is in the open state, the zipper on the side wall of the protective cover 1 opens, or the elastic material protective cover 1 flips over, so that the protective cover 1 also unfolds with the fixing unit 2, facilitating the installation and removal of the protective tooling, simplifying the installation and removal steps, and reducing the difficulty of installation and removal.

[0044] When the first side wall 12 and the second side wall 13 are enclosed by a zipper to form the protective space 11, when the fixing unit 2 switches between the open state and the closed state, the zipper needs to be opened or closed in advance to adapt to the state of the fixing unit 2 so that the protective tooling can be disassembled or installed on the wind vane.

[0045] When the first side wall 12 and the second side wall 13 are fastened together to form the protective space 11, when the fixing unit 2 switches between the open state and the closed state, the fixing unit 2 can drive the first side wall 12 and the second side wall 13 to open or close.

[0046] When the first side wall 12 and the second side wall 13 are made of elastic material as an integral structure, when the fixing unit 2 switches between the open state and the closed state, the protective cover 1 needs to be folded in advance to adapt to the state of the fixing unit 2 so that the protective tooling can be disassembled or installed on the wind vane.

[0047] Of course, in the embodiment of the present application, the protective cover 1 is not limited to the above structure, and those skilled in the art can configure it according to actual needs.

[0048] The positioning portion 21 and the clamping portion 23 are rotatably connected via the rotating portion 22, so that the fixing unit 2 forms a clamshell structure. When the fixing unit 2 is installed on the weather vane 3, the positioning portion 21 is fixed to the weather vane 3, and the clamping portion 23 is rotated so that the clamping portion 23 rotates around the axis of the rotating portion 22, thereby gradually reducing the angle between the clamping portion 23 and the positioning portion 21 until the clamping portion 23 and the positioning portion 21 are closed, thereby fixing the fixing unit 2 on the weather vane 3. The protective cover 1 is connected to the fixing unit 2. During the installation process of the fixing unit 2, the protective cover 1 gradually covers the weather vane 3 and covers the fixing unit 2 within the protective space 11. The side walls of the protective cover 1 are connected by zippers or buckles, so that the protective cover 1 protects the fixing unit 2 and the weather vane 3. At the same time, the connection between the fixing unit 2 and the weather vane 3 can strengthen the stability of the protective cover 1 on the weather vane 3 and prevent the protective cover 1 from falling off due to bad weather.

[0049] When it is necessary to remove the fixing unit 2 from the weather vane 3, the zipper or other components on the sidewalls of the protective cover 1 are opened to unfold the first sidewall 12 and the second sidewall 13 of the dust cover 1. The clamping portion 23 is then rotated about the axis of the rotating portion 22, thereby gradually increasing the angle between the clamping portion 23 and the positioning portion 21 until there is sufficient space for the positioning portion 21 to separate from the weather vane 3. The protective cover 1 is connected to the fixing unit 2. During the removal of the fixing unit 2, the protective cover 1 gradually unfolds and separates from the weather vane 3 along with the fixing unit 2, thereby removing the protective tooling, thereby improving the accuracy and reliability of the weather vane-type sideslip angle sensor during aircraft flight.

[0050] The positioning portion 21 and the clamping portion 23 are rotatably connected via the rotating portion 22 to switch between an open state and a closed state. When the positioning portion 21 and the clamping portion 23 are in the closed state, the positioning portion 21 and the clamping portion 23 are in contact with each other on their adjacent sides. The side of the positioning portion 21 that contacts the clamping portion 23 is a first contact surface, and the side of the clamping portion 23 that contacts the positioning portion 21 is a second contact surface.

[0051] At least one of the first and second contact surfaces is provided with a retaining groove. In this embodiment, the weather vane 3 includes a transverse wind direction rod 32 and a longitudinal support rod 31. The retaining groove is T-shaped to accommodate the weather vane. By providing a retaining groove in the fixing unit 2 to define the position of the fixing unit 2 on the weather vane 3, the stability of the connection between the protective tooling and the weather vane 3 is improved.

[0052] Of course, in the embodiment of the present application, the limiting groove is not limited to the above structure, and those skilled in the art can set it according to actual needs.

[0053] For example, a first limiting groove 24 is provided on the first contact surface. The first limiting groove 24 is adapted to the wind direction rod 32 of the wind vane 3 and defines the longitudinal position of the fixing unit 2 on the wind vane 3. A second limiting groove 25 is also provided on the first contact surface. The second limiting groove 25 is adapted to the support rod 31 of the wind vane 3 and defines the transverse position of the fixing unit 2 on the wind vane 3.

[0054] In the embodiment of the present application, the positioning portion 21 and the clamping portion 23 of the fixing unit 2 are rotatably connected through the rotating portion 22, so that the fixing unit 2 can be switched between an open state and a closed state to realize a detachable connection between the fixing unit 2 and the weather vane 3. The first side wall 12 and the second side wall 13 of the protective cover 1 are respectively connected to the positioning portion 21 and the clamping portion 23, so that when the positioning portion 21 and the clamping portion 23 are rotated, the protective cover 1 can be opened and closed along with the fixing unit 2, effectively reducing the difficulty of installing and disassembling the protective tooling and the weather vane type sideslip angle sensor, and the position of the fixing unit 2 on the weather vane 3 is limited by the limiting groove of the fixing unit, effectively improving the connection stability of the protective cover 1 and the weather vane 3 of the weather vane type sideslip angle sensor, thereby improving the dustproof and waterproof performance of the dust cover 1 on the fixing unit 2 and the weather vane 3, and reducing the damage to the weather vane type sideslip angle sensor due to bad weather.

[0055] In one example, the limiting groove includes a first limiting groove 24 and a second limiting groove 25 , wherein the first limiting groove 24 is adapted to the wind direction rod 32 of the weather vane 3 , and the second limiting groove 25 is adapted to the support rod 31 of the weather vane 3 .

[0056] like Figure 6 As shown, the first limiting groove 24 and the second limiting groove 25 are adapted to the wind direction rod 32 and the support rod 31 of the wind vane 3, and are used to limit the position of the fixing unit 2 on the wind vane 3, effectively enhancing the connection stability between the fixing unit 2 and the wind vane 3, and preventing the fixing unit 2 from moving on the wind vane 3 during use, thereby improving the connection stability between the protective cover 1 and the wind vane type sideslip angle sensor.

[0057] The first limiting groove 24 is a horizontal limiting groove adapted to the wind direction rod 32 and used to limit the vertical position of the fixing unit 2 on the weather vane 3. The second limiting groove 25 is a vertical limiting groove adapted to the support rod 31 and used to limit the horizontal position of the fixing unit 2 on the weather vane 3.

[0058] In one example, the first contact surface has a groove 211, and the second contact surface has a protrusion 231 adapted to the groove 211. When the first contact surface and the second contact surface are in contact, the protrusion 231 is embedded in the groove 211 to form a limiting fit, wherein the first limiting groove 24 is provided on the side wall of the groove 211 close to the rotating part 22.

[0059] like Figures 4 to 7 As shown, the positioning portion 21 is in a rectangular block shape, and the end portion of the positioning portion 21 connected to the clamping portion 23 is chamfered.

[0060] A groove 211 is defined on the side of the positioning portion 21 that mates with the clamping portion 23. A first limiting groove 24 is located near the chamfered end of the groove 211. The axis of the first limiting groove 24 is parallel to the axis of the rotating portion 22. When the fixing unit 2 is connected to the weather vane 3, the wind direction rod 32 of the weather vane 3 is embedded in the first limiting groove 24. The first limiting groove 24 defines the vertical position of the fixing unit 2 relative to the weather vane 3.

[0061] The clamping portion 23 is in a rectangular block shape, and an end portion of the clamping portion 23 connected to the positioning portion 21 is chamfered.

[0062] A protrusion 231 is provided on the clamping side that fits against the positioning portion 21. The protrusion 231 fits into the groove 211. When the fixing unit 2 is connected to the weather vane 3, the protrusion 231 is embedded in the groove 211. This limited engagement between the protrusion 231 and the groove 211 strengthens the connection between the positioning portion 21 and the clamping portion 23.

[0063] In one example, a first through groove 251 is provided on the groove 211, and the first through groove 251 is connected to the first limiting groove 24. A second through groove 252 is provided on the protrusion 231. When the first contact surface and the second contact surface are in contact, the first through groove 251 is connected to the second through groove 252 to form the second limiting groove 25.

[0064] like Figures 4 to 7 As shown, a first through-slot 251 is defined within the recess 211. The first through-slot 251 is perpendicular to the first limiting slot 24. The diameter of the first limiting slot 24 matches the outer diameter of the support rod 31 of the weather vane 3. When the fixing unit 2 is connected to the weather vane 3, the support rod 31 of the weather vane 3 is embedded in the first through-slot 251, and the first through-slot 251 defines the lateral position of the positioning portion 21 on the weather vane 3.

[0065] By setting a first limiting groove 24 and a first through groove 251 perpendicular to each other, the position of the positioning portion 21 on the wind vane 3 is limited. By limiting the position of the positioning block, the position of the protective cover 1 on the wind vane 3 is strengthened, and the connection stability of the protective cover 1 and the wind vane 3 is strengthened.

[0066] A second through slot 252 is provided on one side of the clamping portion 23 that can be fitted with the positioning portion 21. The axis of the second through slot 252 is perpendicular to the axis of the rotating portion 22. When the fixing unit 2 is connected to the weather vane 3, the first through slot 251 and the second through slot 252 form a second limiting slot 25. The support rod 31 of the weather vane 3 is embedded in the second limiting slot 25, and the position of the clamping portion 23 in the lateral direction on the weather vane 3 is limited by the second limiting slot 25. By providing the first limiting slot 24 and the second limiting slot 25 that are perpendicular to each other, the position of the fixing unit 2 on the weather vane 3 is limited. By limiting the position of the fixing unit 2, the position of the protective cover 1 on the weather vane 3 is strengthened, thereby strengthening the connection stability between the protective cover 1 and the weather vane 3.

[0067] In one example, a sealing strip 26 is provided on the protrusion 231. When the fixing unit 2 is connected to the weather vane 3, two sealing strips 26 are provided on opposite sides of the support rod 32, and the two sealing strips 26 extend in a direction parallel to the axis of the support rod 32. The sealing strip 26 abuts between the positioning portion 21 and the clamping portion 23, and the sealing strip 26 is squeezed and elastically deformed in the radial direction of the support rod 32.

[0068] like Figures 4 to 7 As shown, a sealing strip 26 is provided on the protrusion 231. The sealing strip 26 is made of a material such as rubber or silicone. The provision of the sealing strip 26 enhances the seal between the positioning portion 21 and the clamping portion 23 when the fixing unit 2 is connected to the weather vane 3, thereby preventing liquids, dust, and other impurities from entering through the gap and damaging the weather vane 3.

[0069] In the embodiment of the present application, the support rod 32 and the wind direction rod 31 are both cylindrical. The first limiting groove 24 and the second limiting groove 25 are also cylindrical and adapted to the wind direction rod 31 and the support rod 32. The sealing strip 26 is in the shape of an elongated strip, and two sealing strips 26 are arranged on opposite sides of the second through groove 252. When the fixing unit 2 is set on the weather vane 3, the sealing strip 26 abuts between the positioning portion 21 and the clamping portion 23, causing the sealing strip 26 to deform along the radial direction of the second limiting groove 25, thereby causing the sealing strip 26 to squeeze the support rod 31 of the weather vane 3, so that a seal is achieved between the sealing strip 26 and the support rod 31, effectively reducing dust, liquid and other impurities from entering the weather vane 3 through the gap.

[0070] Of course, in the embodiment of the present application, the support rod 32, the wind direction rod 31, the first limiting groove 24 and the second limiting groove 25 are not limited to the above structure, and those skilled in the art can make arrangements according to actual needs.

[0071] In one example, the rotating part 22 includes a connecting member 221 and an embedding groove 222, the connecting member 221 is arranged on the clamping part 23, the embedding groove 222 is opened on the positioning part 21, the connecting member 221 and the embedding groove 222 are arranged at adjacent ends of the clamping part 23 and the positioning part 21, and the connecting member 221 is embedded in the embedding groove 222, and the connecting member 221 is coaxially rotatably connected with the embedding groove 222.

[0072] like Figures 4 to 7 As shown, the end of the clamping portion 23 adjacent to the positioning portion 21 has a connecting piece 221. The connecting piece 221 is cylindrical, and the outer wall of the connecting piece 221 transitionally connects to the end of the clamping portion 23. A connecting hole is provided at the axis of the connecting piece 221. The connecting piece 221 is located in the middle of the end of the clamping portion 23.

[0073] The end of the positioning portion 21 adjacent to the clamping portion 23 is chamfered, and an embedding groove 222 is provided in the middle thereof, which is adapted to fit the connecting member 221. The embedding groove 222 has a rotary hole connected to the connecting hole.

[0074] When the positioning part 21 is connected to the clamping part 23, the connecting piece 221 is embedded in the embedding groove 222, and is inserted into the rotating hole through the rotating pin and passes through the connecting hole, so that the positioning part 21 and the clamping part 23 can be rotatably connected, thereby realizing a detachable connection between the fixing unit 2 and the weather vane 3.

[0075] In one example, the fixing unit 2 further includes a first fastener 27 and a second fastener 28, and a plurality of the first fasteners 27 are arranged on the positioning portion 21 and / or the clamping portion 23, and the first fastener 27 is used to fix the positioning portion 21 and the clamping portion 23; a plurality of the second fasteners 28 are arranged on the protective cover 1 and connected to the fixing unit 2, and the second fasteners 28 are used to fix the protective cover 1 and the fixing unit 2.

[0076] like Figures 1 to 7 As shown, the first fastener 27 is a bolt fastener, and a bolt hole is opened on the positioning portion 21. The bolt fastener passes through the positioning portion 21 and is connected to the clamping portion 23, so that the positioning portion 21 and the clamping portion 23 are connected and fixed to prevent the clamping portion 23 and the positioning portion 21 from loosening.

[0077] Of course, in the embodiment of the present application, the first fastener 27 is not limited to the above structure and position, and those skilled in the art can configure it according to actual needs. For example, a bolt hole is provided in the clamping portion 23, and a bolt fastener passes through the clamping portion 23 and connects to the positioning portion 21, thereby connecting and fixing the positioning portion 21 to the clamping portion 23.

[0078] like Figures 1 to 7As shown, the second fastener 28 is an anti-slip butterfly bolt. The anti-slip butterfly bolt connects and fixes the fixing unit 2 to the protective cover 1, so that the protective cover 1 can be opened or closed with the fixing unit 2, so as to facilitate the easy installation and removal of the protective tooling and the weather vane 3.

[0079] In one example, the protective cover 1 is made of soft material, and the first side wall 12 and the second side wall 13 are enclosed by a zipper to form the protective space 11 .

[0080] like Figures 1 to 4 As shown, the protective cover 1 is made of a soft material such as a three-proof cloth, and the first side wall 12 is connected to the second side wall 13 on the side close to the rotating portion 22. When the fixed unit 2 is closed, the first side wall 12 and the second side wall 13 are folded. When the fixed unit 2 is in the closed state, the first side wall 12 and the second side wall 13 are closed by a zipper on the side of the protective cover 1, so that the first side wall 12 and the second side wall 13 enclose the protective space 11, reducing the risk of dust and other impurities entering the protective space 11 through the gap between the first side wall 12 and the second side wall 13 and damaging the weather vane 3 and the fixed unit 2 located within the protective space 11.

[0081] Of course, in the embodiment of the present application, the protective cover 1 is not limited to the above materials, and those skilled in the art can configure it according to actual needs. For example, the protective cover 1 can also be made of an elastic material, and the first side wall 12 and the second side wall 13 are an integral structure. By designing the protective cover 1 as an integral structure, the connection seams of the protective cover 1 can be reduced, thereby effectively reducing the ingress of dust, impurities, etc. into the protective space 11, and effectively strengthening the protection of the weather vane 3.

[0082] According to another embodiment of the present application, a wind vane type sideslip angle sensor is provided, which includes a wind vane type sideslip angle sensor body 4 and the protective tooling as described above, wherein the wind vane type sideslip angle sensor body 4 has the wind vane 3, and the protective tooling is arranged on the wind vane 3.

[0083] like Figures 1 to 5 As shown, this protective fixture is applied to a weathervane-type sideslip angle sensor. The weathervane-type sideslip angle sensor body 4 includes a weathervane 3, and the protective fixture is detachably mounted on the weathervane 3. This protective fixture features a small size, light weight, easy assembly and disassembly, a stable structure, and strong protective properties. Compared to existing protective fixtures, the protective fixture of this application has greater durability and reliability.

[0084] In one example, the weather vane 3 includes a support rod 31 and a wind direction rod 32, and the limiting groove includes a first limiting groove 24 and a second limiting groove 25. When the fixing unit 2 is in a closed state, the wind direction rod 32 is located in the first limiting groove 24, and the support rod 31 is located in the second limiting groove 25.

[0085] like Figures 1 to 5 As shown, the support rod 31 is a longitudinal rod provided on the weather vane side slip angle sensor body 4, and the wind direction rod 32 is a horizontal rod provided on the top of the support rod 31. The first limiting groove 24 is a horizontal limiting groove adapted to the wind direction rod 32, and the second limiting groove 25 is a vertical limiting groove adapted to the support rod 31.

[0086] The wind vane 3 includes a support rod 31 connected to the wind vane-type sideslip angle sensor body 4. A wind direction rod 32 is located at the end of the support rod 31 facing away from the wind vane-type sideslip angle sensor body 4. A blade is disposed at one end of the wind direction rod 32. When the fixed unit 2 is connected to the wind vane 3, the rotating portion 22 of the fixed unit 2 and the blade are on the same side of the wind direction rod 32, and the top of the fixed unit 2 is aligned with the top of the blade. By aligning the height of the fixed unit 2 with the top of the blade, the protective cover 1 is supported by the fixed unit 2 when the protective tooling is mounted on the wind vane 3, reducing the weight on the blade and providing a certain degree of protection for the blade.
