Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a locking structure based on a lateral elastic support system. Background Technology

[0002] Fixed-wing UAVs are a type of drone characterized by their fixed wings. They generate lift through the pressure difference created by airflow over the wings, unlike rotary-wing UAVs which rely on rotating wings. Their flight principle is similar to that of traditional fixed-wing aircraft, but they are typically smaller, more maneuverable, and can achieve automated flight through pre-programmed instructions.

[0003] Fixed-wing drones typically use a locking structure to connect their fuselage and wings. However, traditional drone fuselage locking structures often employ vertical or linear spring designs, which suffer from insufficient lateral support, complex structures, and poor locking stability. Therefore, improvements are needed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a locking structure based on a lateral elastic support system, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A locking structure based on a lateral elastic support system includes a lateral spring support frame.

[0007] The most significant design difference of this utility model is that the lateral spring support frame includes a support base, a base cover plate on one side of the support base, a pressing slider on the top of the support base, the pressing slider being T-shaped, and the bottom end of the pressing slider penetrating through the top of the support base and slidably inserted into the support base. A locking tongue is slidably inserted into one side of the base cover plate, and one end of the locking tongue sequentially penetrates the base cover plate, the pressing slider, and the support base. Two sliding locking blocks are symmetrically distributed inside the support base, and the two sliding locking blocks can move laterally within the support base. A side spring assembly is provided between one side of the support base and the sliding locking blocks.

[0008] Specifically, the side spring assembly includes two sets of compression springs symmetrically distributed, with two compression springs in each set. Both compression springs are located between the support base and the sliding lock block, and the two ends of the compression springs are fixedly connected to one side of the inner wall of the support base and one side of the sliding lock block, respectively.

[0009] Specifically, the front end of the latch is inverted wedge shape, and the end of the latch is provided with an inclined guide surface.

[0010] Compared with the prior art, this utility model has the following advantages: through the coordinated design of the lateral spring assembly and the sliding lock block, the lateral elastic locking and quick release of the drone body are realized, solving the pain points of weak lateral load-bearing capacity and complicated operation of traditional vertical locks.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figure 1 As shown, this utility model provides a locking structure based on a lateral elastic support system, including a lateral spring support frame, which is fixed inside the middle section of the UAV fuselage, and the interior is guided by a lateral slide rail for lateral movement of the locking mechanism.

[0021] like Figure 2-7As shown, the most significant design difference of this utility model is that the lateral spring support frame includes a support base 1, a base cover plate 2 is provided on one side of the support base 1, a pressing slider 3 is provided on the top of the support base 1, the pressing slider 3 is T-shaped, and the bottom end of the pressing slider 3 passes through the top of the support base 1 and is slidably inserted into the support base 1. A locking tongue 4 is slidably inserted on one side of the base cover plate 2, and one end of the locking tongue 4 passes through the base cover plate 2, the pressing slider 3 and the support base 1 in sequence. Two sliding locking blocks 5 are symmetrically distributed in the support base 1, and the two sliding locking blocks 5 can move laterally in the support base 1. A side spring assembly is provided between one side of the support base 1 and the sliding locking blocks 5.

[0022] like Figure 3 and Figure 7 As shown, the side spring assembly includes two sets of compression springs 6 symmetrically distributed, and each set of compression springs 6 consists of two springs. Both compression springs 6 are located between the support base 1 and the sliding lock block 5, and the two ends of the compression springs 6 are fixedly connected to one side of the inner wall of the support base 1 and one side of the sliding lock block 5, respectively.

[0023] like Figure 5 As shown, the front end of the latch 4 is inverted wedge shape, and the end of the latch 4 is provided with an inclined guide surface.

[0024] The specific working principle is as follows: When in use, the locking tongue 4 is used to fix the wing accessories. When the wing is inserted into the fuselage body, one end of the locking tongue 4 is inserted into the support base 1. The sliding locking block 5 in the support base 1 is squeezed and pushed back, while squeezing the compression spring 6. When the locking tongue 4 is inserted to the limit position, the sliding locking block 5 is forced into the narrow section in the middle of one end of the locking tongue 4, forming a blocking and pushing back. At this time, the play in the lateral, vertical, forward and backward movement of the lock head disappears, and a tight locking state is formed.

[0025] When it is necessary to disconnect the wing from the main body, press the slider 3. The vertical force will be transformed into the lateral displacement power source through the sliding lock block 5. At the same time, the wedge-shaped surface of the sliding lock block 5 slides out of the narrow range set at one end of the locking tongue 4, forming lateral, forward, and backward movement play. At this time, the locking tongue 4 can be pulled out, and the wing can be separated from the main body of the drone.

[0026] Compared with the prior art, this utility model has the following advantages: through the coordinated design of the lateral spring assembly and the sliding lock block 5, the lateral elastic locking and quick release of the drone body are realized, which solves the pain points of weak lateral load-bearing capacity and complicated operation of traditional vertical locks.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
