[0024] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0025] Please see Figure 1 This embodiment provides a measuring device 100, suitable for drone angle testing applications. The measuring device 100 includes a base 10, a test frame 20, and an angle adjustment mechanism 30.
[0026] The base 10 serves as the fundamental support platform for the entire measuring device 100, ensuring a stable reference surface during testing. The test frame 20, located on the upper layer of the device, is specifically designed to support the object under test, and its structural design fully considers the installation requirements of UAVs of different sizes. The angle adjustment mechanism 30, as a core functional component, is mounted on the base 10 and establishes an adjustable connection with the test frame 20.
[0027] Please see Figure 2 and Figure 3 The angle adjustment mechanism 30 includes a first adjustment component 31, which includes a first adjustment element 301, a first universal joint structure 302, and a first length adjustment structure 303. The first universal joint structure 302 is connected to the first adjustment element 301 and the first length adjustment structure 303, respectively. The first length adjustment structure 303 is used to adjust the effective length of the first adjustment component 31, and the first universal joint structure 302 and the first adjustment element 301 form a universal fit.
[0028] For details, please continue reading. Figure 3The first adjusting element 301 includes a first adjusting rod 311 and a first ball head 312. The first ball head 312 is fixedly disposed at one end of the adjusting rod, forming the geometric basis for a universal connection. The first adjusting rod 311 adopts a cylindrical structure to ensure sufficient mechanical strength and force transmission capacity. The first universal joint structure 302 includes a first universal sleeve 321 and a first clamping assembly 322, playing a key role in realizing the universal joint function. The first ball head 312 is disposed within the first clamping assembly 322, and the first adjusting rod 311 is disposed within the first universal sleeve 321. One end of the first clamping assembly 322 is disposed within the first universal sleeve 321, and the other end of the first clamping assembly 322 is connected to the test frame 20. The first adjusting element 301 achieves universal joint connection with the test frame 20 through the first clamping assembly 322. One end of the first length adjusting structure 303 is connected to the base 10, and the other end of the first adjusting rod 311 is connected to the other end of the length adjusting structure. Through the above arrangement, the first adjusting element 301 achieves universal joint connection with the test frame 20 through the first clamping assembly 322. The first clamping assembly 322 adopts a two-piece structure design, including a first clamping member 323 and a second clamping member 333. The first ball head 312 is located between the two clamping members, forming an effective clamping configuration. The first clamping member 323 and the second clamping member 333 precisely restrict the axial movement of the first ball head 312 within the first universal sleeve 321 through mutual compression. The above arrangement ensures axial positioning accuracy while maintaining the radial and angular degrees of freedom of the ball head, thus realizing the universal connection function.
[0029] The first length adjustment structure 303 includes a first adjustment column 331, a first adjustment cylinder 332, and a first adjustment bolt 333. 331 serves as a basic support element and is fixedly connected to the base 10, providing a stable structural reference. The first adjustment column 331 has several first insertion holes (not shown) and second insertion holes (not shown) arranged axially. The first insertion holes (not shown) and second insertion holes (not shown) are configured in a one-to-one correspondence, forming paired insertion hole combinations. The axial distribution of the insertion holes is precisely positioned according to a preset length adjustment increment, ensuring the geometric accuracy of each adjustment position. The first adjustment cylinder 332, as an adjustable element, is structurally designed to cooperate with 331. The first adjustment cylinder 332 also has several third insertion holes (not shown) and fourth insertion holes (not shown) arranged axially. The third insertion holes (not shown) and fourth insertion holes (not shown) are configured in a one-to-one correspondence. The insertion hole distribution of the first adjustment cylinder 332 maintains geometric coordination with the insertion hole distribution of the first adjustment column 331, ensuring reliable cooperation at different adjustment positions. The first adjusting bolt 333 passes sequentially through the third socket, the first socket, and the second socket, finally settling into the fourth socket to form a complete adjustable connection link. The length adjustment process is achieved by selecting different socket combinations. The operator selects the corresponding first and second socket combinations according to the target adjustment length, while simultaneously determining the positions of the corresponding third and fourth sockets. The insertion sequence of the first adjusting bolt 333 ensures accurate alignment of each socket, forming a stable geometric constraint relationship. Different socket combinations correspond to different relative positions between the adjusting cylinder and the adjusting post, thereby achieving the preset length adjustment function.
[0030] Please refer to the following: Figure 2 The angle adjustment mechanism 30 further includes a second adjustment component 32, a third adjustment component 33, and a fourth adjustment component 34. The first adjustment component 31, second adjustment component 32, third adjustment component 33, and fourth adjustment component 34 are respectively located at the four corners of the base 10, forming a stable rectangular support geometry. Each adjustment component has the same structural configuration as the first adjustment component 31, including three functional modules: an adjustment element, a universal connection structure, and a length adjustment structure, ensuring system standardization and interchangeability. Specifically, the length difference between any two adjacent adjustment components achieves the angular tilt of the test frame 20 along the first axis, and the length difference between any two opposite adjustment components achieves the angular tilt of the test frame 20 along the second axis.
[0031] Preferably, the first adjustment component 31 and the third adjustment component 33 are positioned diagonally opposite each other on the base 10, and the second adjustment component 32 and the fourth adjustment component 34 are similarly positioned diagonally opposite each other. An appropriate spacing is maintained between adjacent adjustment components, forming a stable supporting triangular geometry to ensure the structural stability of the test frame 20 under various angle conditions. When it is necessary to tilt the test frame 20 along the first axis, the length difference between any two adjacent adjustment components is adjusted. By increasing the length of one adjacent component and correspondingly decreasing the length of the other adjacent component, the test frame 20 generates a preset tilt angle along that axis. The angle directly corresponds to the length difference between adjacent components, providing precise angle control.
[0032] The tilt angle of the second axis is achieved by adjusting the length difference between two opposing adjustment components. For example, the first adjustment component 31 and the third adjustment component 33 form one pair of opposing components, and the second adjustment component 32 and the fourth adjustment component 34 form another pair of opposing components. By adjusting the length difference between the opposing components, the test fixture 20 is tilted at an angle in the direction perpendicular to the first axis.
[0033] In this embodiment, by simultaneously adjusting the length ratio of four adjustment components, the test frame 20 can achieve compound angle tilting in any direction. Operators can independently adjust the length of each component according to testing requirements, achieving single-axis tilting, dual-axis tilting, or complex spatial angle combinations. The universal joint structure of each adjustment component ensures that each connection point can adaptively adjust during compound angle adjustment, avoiding geometric constraint conflicts. Precision control of length adjustment is achieved through the threaded transmission mechanism of each component. The length adjustment structure of each adjustment component provides independent adjustment capability, allowing operators to precisely set the target length of each component based on angle calculation results. The self-locking characteristic of the threaded transmission ensures long-term stability of the position after adjustment, preventing position drift caused by external forces or vibration. During operation, the operator first determines the target angle parameters according to testing requirements and determines the target length configuration of each adjustment component through geometric calculations. Then, the length adjustment structure of each component is adjusted sequentially to achieve the preset angle configuration. During adjustment, the universal joint structure ensures that the test frame 20 smoothly transitions to the target angle state, avoiding impact on the test object caused by sudden posture changes.
[0034] Please see Figure 4The measuring device 100 further includes a fixing component 40. The angle adjustment mechanism 30 is connected to the test frame 20 and the base 10 respectively through the fixing component 40. Specifically, the fixing component 40 includes a first fixing plate 41, a second fixing plate 42, and a first fixing post 43. The first fixing plate 41 has a first through hole 411, and the second fixing plate 42 has a second through hole 421. One end of the first length adjustment structure 303 passes through the first through hole 411 and is fixedly connected to the base 10 to form a stable support foundation. The first through hole 411 is designed to ensure the axial freedom of the length adjustment structure during operation, while providing necessary radial constraints to prevent unnecessary lateral displacement during adjustment. One end of the first fixing post 43 is connected to the test frame 20, and the other end of the first fixing post 43 passes through the second through hole 421 and is connected to the first adjustment element 301. The first fixing plate 41 serves as the lower connection interface, responsible for establishing the connection between the angle adjustment mechanism 30 and the base 10. The second fixing plate 42 serves as the upper connection interface, responsible for establishing the connection between the angle adjustment mechanism 30 and the test frame 20. Furthermore, the fixing assembly 40 also includes a second fixing post 44, a third fixing post 45, and a fourth fixing post 46. The first fixing post 43, the second fixing post 44, the third fixing post 45, and the fourth fixing post 46 are respectively disposed at the four corresponding corner positions of the second fixing plate 42. The first fixing post 43, the second fixing post 44, the third fixing post 45, and the fourth fixing post 46 are respectively connected to the first adjusting element 301, the second adjusting element, the third adjusting element, and the fourth adjusting element to form a complete configuration of four-point fixing. This configuration forms a geometric correspondence with the four-corner layout of the base 10, thereby realizing the effective transmission of force and the reliable realization of the angle adjustment function.
[0035] In this embodiment, both the first fixing plate 41 and the second fixing plate 42 adopt a flat plate structure. The selection of the plate material takes into account both strength requirements and weight control, ensuring that sufficient support capacity is provided without significantly increasing the weight burden of the overall device. Regarding the assembly process, the fixing component 40 provides a standardized installation procedure. The first fixing plate 41 first establishes a fixed connection with the base 10, followed by the installation of each length adjustment structure. The second fixing plate 42 establishes a connection with the test frame 20 through fixing columns, and finally completes the connection configuration of each adjustment element with the fixing columns. The modular assembly method significantly simplifies the installation process, improves assembly efficiency and quality control. When it is necessary to replace or repair a component of the angle adjustment mechanism 30, partial maintenance can be achieved by disassembling the corresponding fixing connection without disassembling the entire device. The standardized design of the fixing component 40 also provides convenient conditions for spare parts management and rapid maintenance.
[0036] In this embodiment, the first adjusting cylinder 332 is provided with a locking structure (not shown). This locking structure is used to lock the threaded engagement position between the first adjusting cylinder 332 and the first adjusting pin 331. Specifically, the 331 is provided with several locking threaded holes, through which the locking screw passes into the adjusting cylinder. The machining accuracy of the threaded holes ensures a reliable fit between the locking screw and the adjusting cylinder, while providing sufficient adjustment stroke to accommodate different levels of locking requirements. The locking structure is designed to adapt to the plug-in length adjustment mechanism. The locking structure uses radial force to fix the first adjusting cylinder in a preset adjustment position, ensuring the stability of the fit between the adjusting pin and each plug.
[0037] The locking mechanism employs a distributed screw configuration, with multiple locking screws evenly distributed along the circumference of the adjusting cylinder. In a socket-type structure, the locking screws primarily function to enhance the tightness of the fit between the adjusting pin and the socket, preventing loosening or displacement of the adjusting pin due to external loads. The direction and magnitude of the locking force are specifically designed to ensure effective locking without causing excessive stress concentration on the adjusting pin or socket.
[0038] The first length adjustment structure 303 includes a first adjustment column 331 and a first adjustment cylinder 332. The first adjustment column 331 is fixedly connected to the base 10, providing a stable support foundation and a reference surface for threaded engagement. The first adjustment cylinder 332 is adjustablely connected to the first adjustment column 331 via a precision thread. One end of the first adjustment rod 311 is also adjustablely connected to the first adjustment cylinder 332 via a threaded engagement, forming a complete length adjustment transmission link. The locking structure 50 fixes the first adjustment cylinder 332 in a preset adjustment position through radial force. The magnitude and distribution of this force are precisely designed to ensure that sufficient locking force is provided without causing excessive stress or wear on the threaded mating surfaces. The radial locking principle is based on the principle of friction mechanics. By increasing the normal pressure between the mating surfaces, the frictional resistance is increased, achieving reliable position locking. Specifically, the locking structure 50 is located on the outer surface of the first adjustment cylinder 332. Through mechanical action, a radial compressive force is applied to the adjustment cylinder, allowing operators to easily perform locking and unlocking operations while ensuring long-term stability in the locked state.
[0039] This application provides a measuring device 100, including a base 10, a test frame 20, and an angle adjustment mechanism 30. The test frame 20 is used to support the object to be tested. The angle adjustment mechanism 30 is disposed on the base 10 and connected to the test frame 20. The angle adjustment mechanism 30 includes a first adjustment component 31, which includes a first adjustment element 301, a first universal joint structure 302, and a first length adjustment structure 303. The first universal joint structure 302 is connected to the first adjustment element 301 and the first length adjustment structure 303, respectively. The first length adjustment structure 303 is used to adjust the effective length of the first adjustment component 31. The first universal joint structure 302 and the first adjustment element 301 form a universal joint. Through the first adjustment component 31, the test frame 20 can achieve multi-angle tilting composite motion, improving the realism and completeness of the test conditions, more accurately simulating various attitude changes of the UAV during actual flight, and through the cooperation of the first length adjustment structure 303, the user can quickly adjust the height of each support point without frequent disassembly and reassembly of the entire equipment, significantly improving testing efficiency and reducing operational safety risks.
