Description

Technical Field

[0001] The present application relates to the field of drone accessories, and more specifically to a universal external compass fixing structure for drone tripods. Background Art

[0002] Currently, most open-source drone compasses are installed inside the flight control system or an external GPS module. When the compass is installed inside the flight control system, it is subject to significant electromagnetic interference from the flight control's electronic control circuits, battery, and other circuits, which can seriously affect the drone's flight stability. When the compass is installed inside an external GPS module, the external GPS module is typically placed above the drone's main body, and the top of the drone is often used as an expansion area for sensor components such as lidar and onboard computers. These sensor components all contain power modules, and the magnetic field they generate can still interfere with the external drone compass. This is especially true when the motor in the lidar module is powered on, generating a strong magnetic field that can significantly interfere with the drone's compass. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] Example

[0032] like Figure 1-3 As shown, a universal external compass fixing structure for drone tripods includes a vertical bracket 100 whose upper end is fixed to the drone body, a horizontal bracket 200 horizontally arranged at the bottom end of the vertical bracket 100, and a compass fixing structure 300 that is penetrated by the horizontal bracket 200 and fixed to the vertical bracket 100; the compass fixing structure 300 is composed of a compass base 310 and a compass cover 320 arranged on the compass base 310.

[0033] Both the vertical and horizontal brackets are conventional, and are preferably made of carbon fiber tubes, which can reduce the weight of the brackets while ensuring their strength. A fixed tee is provided at the contact point between the vertical and horizontal brackets to securely connect them, and a buffer is also provided at the end of the horizontal bracket. These fixed tee and buffer are also conventional and will not be described in detail here.

[0034] like Figure 4 、 5 As shown, the compass base 310 consists of a base body 311, a rear convex portion 312 formed by the rearward convexity of the upper part of the base body 311, an embedding groove 313 vertically passing through the rear convex portion 312, a through hole 315 provided at the lower part of the base body 311 and passing through the base body 311 front and back, and a compass fixing structure provided on the front side of the base body 311; the compass fixing structure is located above the through hole 315.

[0035] The through-hole provides a passage for the horizontal bracket. Since the horizontal bracket passes through the through-hole, even if the product fails to securely attach to the vertical bracket, the product will not fall off the drone tripod, thereby improving the product's stability and safety. It should be noted that after the horizontal bracket passes through the through-hole, the lowest level of the base body must be higher than the lowest level of the buffer head provided at the end of the horizontal bracket. This will better protect the base body from frequent collisions or friction with the ground, thus ensuring the product's safety.

[0036] The embedding groove 313 is in an arc shape, and the curvature of the embedding groove 313 matches the diameter of the vertical bracket 100 .

[0037] Since the embedded slot matches the vertical bracket, the seismic resistance of the product can be greatly improved after the product is fixed, and the occurrence of the fixing screws falling off due to high-frequency vibration is reduced.

[0038] The compass fixing structure consists of a cover groove 317, a fixing hole 314 set in the cover groove 317 and passing through the base body 311 and the rear protrusion 312, a plurality of fixing blind holes 316 set in the cover groove 317, and a compass embedding groove 319 set at the bottom of the cover groove 317.

[0039] There are four fixing blind holes 316 , and the fixing blind holes 316 are respectively arranged adjacent to the compass embedding slots 319 .

[0040] The center axis of the fixing hole 314 is vertically arranged on the vertical center line of the compass base 310 .

[0041] Since the fixing hole is set on the vertical center line of the compass base, the weight of the left and right sides of the product is basically the same, further reducing the vibration balance of the product during use.

[0042] The bottom of the compass embedding groove 319 is further provided with a wiring hole 318 that passes through the base body 311 and the rear protrusion 312 .

[0043] The reserved wiring holes can meet the wiring requirements of the compass. If suitable holes are set on the vertical bracket in advance, the connecting wires can be completely hidden, further protecting the safety of the wiring.

[0044] like Figure 6 As shown, the compass cover 320 is composed of an upper cover body 321 , and a through hole 322 and a cover fixing hole 323 provided on the upper cover body 321 .

[0045] The shape and thickness of the upper cover body 321 match the compass embedding groove 319 .

[0046] Matching the thickness of the upper cover body with the compass embedding slot allows the front of the base body to present a flat surface after the upper cover body is installed, effectively reducing wind resistance and further ensuring the stability of the drone's flight.

[0047] The diameter of the through hole 322 is greater than or equal to the maximum diameter of the fixing hole 314 ; the position of the cover fixing hole 323 matches the fixing blind hole 316 .

[0048] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0049] In addition, the above-mentioned specific embodiments are merely illustrative. Those skilled in the art may devise various solutions based on the disclosure of this utility model, and such solutions fall within the scope of disclosure and the scope of protection of this utility model. Those skilled in the art should understand that the specification and drawings of this utility model are illustrative and do not constitute limitations of the claims. The scope of protection of this utility model is defined by the claims and their equivalents.
