Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to an installation structure for an UAV route navigation signal acquisition system. Background Technology

[0002] The UAV route navigation signal acquisition system, often referred to as the flight controller or navigation core module, is an integrated system used to acquire, process, and transmit navigation data (such as position, speed, altitude, and heading) required during UAV flight. This system typically relies on satellite navigation (GPS / BeiDou / GLONASS), inertial navigation (IMU), and data link communication, and works in conjunction with a ground control station to achieve route planning and real-time adjustments.

[0003] The core components of a UAV route navigation signal acquisition system may adopt an integrated modular design (a compact form similar to a "hard drive") or a distributed independent unit. Integrated modular design reduces cable connections by directly fixing to the fuselage through reserved interfaces, which simplifies the installation structure and saves space, making it suitable for small UAVs.

[0004] The existing drones use mounting boxes for the navigation core module. The navigation core module is simply plugged into the mounting box, but the mounting box lacks a clamping structure for the navigation core module. When subjected to vibration, the navigation core module is prone to loosening, affecting normal use. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where the mounting box lacks a structure to clamp and fix the navigation core module during installation, making the connection prone to loosening due to vibration. Therefore, this invention proposes an installation structure for an unmanned aerial vehicle (UAV) route navigation signal acquisition system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An installation structure for a UAV route navigation signal acquisition system includes a fixed box installed inside the UAV body, and an end cover that can be detached from the opening end of the fixed box. An arc-shaped elastic sheet is fixedly provided on the inner wall of the end cover. When one end of the navigation core module is inserted into the fixed box, the end cover covers the opening end of the fixed box, and the protruding part of the elastic sheet abuts against the other end of the navigation core module and undergoes elastic deformation.

[0008] To improve the clamping effect on the navigation core module, preferably, multiple elastic sheets are equidistantly arranged along the length direction of the end cap.

[0009] In order to maintain a certain elastic modulus, the thickness of the elastic sheet is preferably in the range of 1mm-5mm.

[0010] To increase the service life and clamping effect of the elastic sheet, preferably, the elastic sheet is made of spring steel.

[0011] Preferably, the fixed box has a threaded hole at its open end, and the end cover has a countersunk hole. The end cover is detachably connected to the fixed box by screws.

[0012] Preferably, both sides of the inner wall of the fixing box are fixedly provided with arc-shaped limiting pieces, and the protruding parts of the limiting pieces abut against the two sides of the navigation core module.

[0013] Furthermore, the limiting piece is made of engineering plastic.

[0014] Preferably, the drone body has an installation cavity, and the outer walls on both sides of the fixing box are fixedly provided with fixing plates, which are fixedly installed in the installation cavity by bolts.

[0015] Furthermore, the end cap is disposed at one end of the fixing box that extends into the mounting cavity.

[0016] Preferably, the top and bottom of the fixing box are provided with long strip-shaped ventilation grooves, and multiple sets of ventilation grooves are equidistantly arranged along the insertion direction of the navigation core module.

[0017] Compared with the prior art, this utility model provides an installation structure for an unmanned aerial vehicle (UAV) route navigation signal acquisition system, which has the following advantages:

[0018] 1. The installation structure of the UAV route navigation signal acquisition system involves removing and installing an end cover at the opening end of the fixed box, and fixing an elastic sheet on the inner wall of the end cover. When the navigation core module is correctly inserted into the fixed box, and the end cover is fixed at the opening end of the fixed box, the protruding part of the elastic sheet on the inner wall of the end cover abuts against the navigation core module and undergoes elastic deformation. Under the elastic clamping of the elastic sheet, the loosening phenomenon can be reduced when the navigation core module is subjected to vibration, thus ensuring normal use.

[0019] 2. The installation structure of the UAV route navigation signal acquisition system uses limit plates fixed on both sides of the inner wall of the fixed box. The protrusions of the limit plates abut against the outer walls on both sides of the navigation core module. During use, the navigation core module can be guided and limited, improving the performance.

[0020] 3. The installation structure of the UAV route navigation signal acquisition system allows the end cap to be fixed to the mounting box by passing one end of a screw through a countersunk hole and threading it into a threaded hole inside the mounting box. In order to improve the sealing effect between the end cap and the UAV body, an annular sealing gasket is fixedly installed on the inner wall of the opening end of the mounting cavity. When the end cap is fixed to the mounting box, the outer walls of the end cap can be abutted by the sealing gasket to increase the sealing performance and help improve the dustproof and waterproof effect.

[0021] All parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model removes and installs an end cap at the opening end of the fixed box, and fixes an elastic sheet on the inner wall of the end cap. When the navigation core module is correctly inserted into the fixed box, and the end cap is fixed at the opening end of the fixed box, the protruding part of the elastic sheet on the inner wall of the end cap abuts against the navigation core module and undergoes elastic deformation. Under the elastic clamping of the elastic sheet, the loosening phenomenon can be reduced when the navigation core module is subjected to vibration, ensuring normal use. Attached Figure Description

[0029] Example:

[0030] Reference Figures 1-4 An installation structure for an unmanned aerial vehicle (UAV) route navigation signal acquisition system includes a fixed box 2 installed inside the UAV body 1. The UAV body 1 has an installation cavity 101. Fixed plates 201 are fixedly installed on both outer walls of the fixed box 2. There are two to six fixed plates 201, preferably four, meaning two fixed plates 201 on each side of the fixed box 2. Through holes are provided on the fixed plates 201. The fixed plates 201 are fixed inside the installation cavity 101 by bolts. In use, the fixed box 2 is fixed inside the installation cavity 101 by threading the bolts through the through holes in the fixed plates 201 and connecting them to the bottom of the installation cavity 101. This design also improves and reduces the impact of vibration on the fixed box 2 and the navigation core module. A rubber pad is provided between the connection surface of the fixed box 2 and the installation cavity 101 to help dampen the fixed box 2 and improve its performance.

[0031] An end cap 3 is detachably installed at the opening of the fixed box 2. That is, the end cap 3 is located at one end of the fixed box 2 extending into the mounting cavity 101. This allows the end cap 3 to be installed and removed from the outside of the drone body 1, facilitating the installation and removal of the navigation core module and improving usability. Here, a connecting plate 4 is fixedly installed inside the fixed box 2, and a connecting terminal 401 is fixedly installed on the connecting plate 4 for electrical connection with the navigation core module. Furthermore, guide posts 402 are fixedly installed at both ends of the connecting plate 4, with the axis of the guide posts 402 aligned with the insertion point of the navigation core module. The two guide posts 402 are parallel to each other, and to ensure the correct insertion direction of the navigation core module and the connection terminal 401, the distances between the two guide posts 402 and the connection terminal 401 are not equal. Therefore, the navigation core module and the connection terminal 401 have only one insertion direction, ensuring a correct connection. In use, the navigation core module is pushed into the fixing box 2 to ensure the connection terminal 401 is correctly inserted into the navigation core module and an electrical connection is achieved. Furthermore, when the fixing box 2 is fixed within the mounting cavity 101, the connection terminal 401 inside the fixing box 2 is connected to the UAV body via a connecting cable. 1. The internal control module is electrically connected. An arc-shaped elastic sheet 302 is fixedly installed on the inner wall of the end cover 3. Here, the elastic sheet 302 is convexly installed on the inner wall of the end cover 3. Multiple elastic sheets 302 are equidistantly arranged along the length of the end cover 3. There are two to five elastic sheets 302. Here, we prefer two. When one end of the navigation core module is inserted into the fixing box 2, the end cover 3 is placed on the opening end of the fixing box 2. At this time, the convex part of the elastic sheet 302 abuts against the other end of the navigation core module and undergoes elastic deformation. Under the elastic action of the elastic sheet 302 This allows for clamping of the navigation core module, which helps reduce the loosening of the connection between the navigation core module and the connecting terminal 401 when subjected to vibration, ensuring normal use. Moreover, in order to make the outer wall of the end cover 3 fit the shape of the outer wall of the UAV body 1, the end cover 3 is set at an angle. An mounting plate 301 is fixedly installed on the inner wall of the end cover 3. The end face of the inner wall of the mounting plate 301 is parallel to the end face of the connecting plate 4. In this case, when multiple elastic pieces 302 are set, the deformation of multiple elastic pieces 302 when they abut against the navigation core module can be kept consistent, which helps to improve the fixing effect.

[0032] In use, the end cap 3 is removed from the opening end of the fixing box 2, and an elastic piece 302 is fixedly installed on the inner wall of the end cap 3. When the navigation core module is correctly inserted into the fixing box 2, and the end cap 3 is fixed at the opening end of the fixing box 2, the protruding part of the elastic piece 302 on the inner wall of the end cap 3 abuts against the navigation core module and undergoes elastic deformation. Under the elastic clamping of the elastic piece 302, the loosening phenomenon can be reduced when the navigation core module is subjected to vibration, ensuring normal use.

[0033] Reference Figure 2 and Figure 3 The thickness of the elastic sheet 302 ranges from 1mm to 5mm. Here, we prefer 3mm, which can increase the clamping effect on the navigation core module while ensuring a certain elastic modulus.

[0034] Reference Figure 3 The elastic sheet 302 is made of spring steel, stainless steel, or beryllium copper alloy. Here, we prefer spring steel, which has excellent elasticity and fatigue resistance. It can maintain its elastic characteristics within a large deformation range and is wear-resistant. This not only increases the service life but also ensures the clamping strength of the navigation core module and improves the performance.

[0035] Reference Figure 3 and Figure 4 A threaded hole is provided on the opening end of the fixing box 2, and a countersunk hole is provided on the end cover 3. The end cover 3 is detached and connected to the fixing box 2 by screws. In use, the end cover 3 can be fixed to the fixing box 2 by passing one end of the screw through the countersunk hole and threading it with the threaded hole in the fixing box 2. In order to improve the sealing effect between the end cover 3 and the drone body 1, an annular sealing gasket is fixedly provided on the inner wall of the opening end of the mounting cavity 101. When the end cover 3 is fixed to the fixing box 2, the outer walls of the end cover 3 can be abutted by the sealing gasket to increase the sealing performance and help improve the dustproof and waterproof effect.

[0036] Reference Figure 2 and Figure 3 An arc-shaped limiting piece 203 is fixedly installed on both sides of the inner wall of the fixing box 2. The protruding parts of the limiting piece 203 abut against the two sides of the navigation core module. Multiple limiting pieces 203 are provided, and they are equidistantly arranged along the insertion direction of the navigation core module. Here, we prefer two. In use, by fixing the limiting pieces 203 on both sides of the inner wall of the fixing box 2 and abutting the protrusions of the limiting pieces 203 against the outer walls of the two sides of the navigation core module, the navigation core module can be guided and limited during use, improving the usage effect. The limiting piece 203 is made of engineering plastic or polyurethane. Here, we prefer engineering plastic, such as polyamide (nylon, PA), which has good mechanical strength, toughness and self-lubricating properties. Although its elasticity is not as good as metal materials, it can ensure the limiting effect.

[0037] Reference Figure 4The top and bottom of the fixed box 2 are provided with long strip-shaped ventilation slots 202, and multiple sets of ventilation slots 202 are equidistantly arranged along the insertion direction of the navigation core module. There are two to five sets of ventilation slots 202. Here, we prefer two sets, with two to ten slots in each set, preferably seven. In use, by opening ventilation slots 202 on the fixed box 2, the heat inside the fixed box 2 can be diffused outward through the ventilation slots 202 during long-term use, which helps to achieve heat dissipation.

[0038] In use, the fixing box 2 is bolted into the mounting cavity 101 inside the UAV body 1, and the connecting terminal 401 is electrically connected to the control module inside the UAV body 1 via a connecting wire. Then, the navigation core module is pushed into the fixing box 2, with the connector of the navigation core module facing into the fixing box 2. Continuing to push the navigation core module allows the connector 401 to continuously engage with the connector, achieving electrical continuity. Then, the end cap 3 is fixed to the open end of the fixing box 2 with screws. At this time, the elastic sheet 302 abuts against the navigation core module and undergoes elastic deformation, which can clamp the navigation core module. When the navigation core module is subjected to vibration, the loosening phenomenon is reduced, ensuring normal use.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
