[0002] In the existing drone pod industry, pods typically incorporate a zoom lens and a laser ranging module. Existing pod structures simply fix the zoom lens and laser ranging module on the same plane. Due to manufacturing tolerances and cumulative tolerances within the modules, there can be significant discrepancies between the object actually viewed by the zoom lens and the object the laser ranging module is aiming at. This results in significant deviations in the measurement results for the object being measured.

[0003] In view of this, it is particularly important to design and manufacture a laser calibration structure, pod and drone. Utility Model Content

DETAILED DESCRIPTION

[0024] In the following detailed description, reference is made to the accompanying drawings, which form a part of the detailed description and are shown by illustrative specific embodiments in which the present application can be practiced. In this regard, directional terms, such as "top", "bottom", "left", "right", "up", "down", etc., are used with reference to the orientation of the figures being described. Because the components of the embodiments can be positioned in several different orientations, directional terms are used for illustrative purposes and are in no way limiting. It should be understood that other embodiments can be utilized or logical changes can be made without departing from the scope of the present application. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present application is defined by the appended claims.

[0025] According to a first aspect of the present application, a laser calibration structure is proposed for use in a drone pod. Figure 1 FIG. 1 shows a schematic diagram of the overall structure of a laser calibration structure according to a specific embodiment of the present application. Figure 1 As shown, the laser calibration structure includes a housing 1, and a zoom lens module 2, a fixed focus lens module 3, a thermal imaging lens module 4, and a laser ranging module 5 arranged in one direction inside the housing 1. Among them, the zoom lens module 2 is a zoom visible light camera.

[0026] Figure 2 FIG. 1 shows a schematic diagram of the internal structure of a laser calibration structure according to a specific embodiment of the present application. Figure 2 As shown, the zoom lens module 2, fixed-focus lens module 3, thermal imaging lens module 4, and laser ranging module 5 are horizontally fixed within the housing 1. However, in practice, due to manufacturing tolerances and accumulated tolerances within the laser ranging module 5, the laser ranging module 5 may deviate slightly horizontally, making it impossible to maintain parallelism with the zoom lens module 2. This can lead to significant deviations between the object actually viewed by the zoom lens module 2 and the object being aligned with the laser ranging module 5, resulting in significant ranging errors. Therefore, the laser calibration structure also includes a displacement adjustment assembly 6 disposed within the housing 1, which is used to calibrate the laser ranging module 5 and the zoom lens module 2 to maintain parallelism on the same plane.

[0027] Continue to refer to Figure 2 Specifically, the laser ranging module 5 has at least one adjustable end 51 circumferentially disposed to be vertically displaced relative to the housing 1. The displacement adjustment assembly 6 is disposed between the adjustable end 51 of the laser ranging module 5 and the housing 1. The displacement adjustment assembly 6 is used to adjust the vertical displacement range of the adjustable end 51 of the laser ranging module 5. This allows the laser ranging module 5 to be calibrated to maintain a parallel position with the zoom lens module 2 on the same plane if the laser ranging module 5 deviates.

[0028] Figure 3 A schematic diagram showing the structure of a displacement adjustment component according to a specific embodiment of the present application is shown. Figure 3 As shown, the displacement adjustment assembly 6 includes an adjustment screw 61, an elastic connector 62, and a first threaded seat 63. A connecting ear 52 is integrally formed on the outer periphery of the laser ranging module 5. The first threaded seat 63 is fixed in the housing 1 below the connecting ear 52. The adjustment screw 61 passes through the connecting ear 52 and is threadedly engaged with the first threaded seat 63. The nut of the adjustment screw 61 abuts the upper end of the connecting ear 52. The elastic connector 62 is sleeved on the screw of the adjustment screw 61. One end of the elastic connector 62 is fixedly connected to the first threaded seat 63, and the other end is fixedly connected to the connecting ear 52.

[0029] In practice, by adjusting the tightening degree of the adjusting screw 61, the adjusting end 51 of the laser ranging module 5 can be displaced vertically, thereby calibrating the laser ranging module 5. Specifically, when the adjusting screw 61 is tightened, the nut of the adjusting screw 61 contacts the upper end of the connecting ear 52, pushing the entire laser ranging module 5 downward and compressing the elastic connector 62. When the adjusting screw 61 is loosened, the laser ranging module 5 moves upward due to the rebound force of the elastic connector 62.

[0030] In this embodiment, the elastic connector 62 is a spring, one end of which is fixed to the upper end of the first threaded seat 63, and the other end of which is sleeved and fixed on the connecting ear 52. In other embodiments, the elastic connector can also be made of other elastic materials such as rubber, which is not limited here.

[0031] Continue to refer to Figure 3 The displacement adjustment assembly 6 also includes a safety screw 64 and a fixing seat 65. A second threaded seat 53 is also provided on the outer periphery of the laser ranging module 5. The second threaded seat 53 is located outside the connecting ear 52 and is integrally connected to the connecting ear 52. The fixing seat 65 is fixed within the housing 1 below the second threaded seat 53. The safety screw 64 is threaded through the second threaded seat 53 and abuts against the fixing seat 65. There is also a certain distance between the nut of the safety screw 64 and the upper end of the second threaded seat 53.

[0032] In a specific implementation, after adjusting the different locking degrees of the adjusting screw 61, since the adjusting screw 61 and the first threaded seat 63 are not completely threaded together, the adjusting screw 61 can easily reset upwards a certain distance after adjustment, driving the laser ranging module 5 to move upward. Therefore, the laser ranging module 5 is tightened by the safety screw 64. Specifically, when the safety screw 64 is tightened downward, the bottom of the safety screw 64 abuts against the fixing seat 65. Since there is a certain distance between the nut of the safety screw 64 and the second threaded seat 53, the second threaded seat 53 will move vertically upward relative to the safety screw 64 and be raised. As a result, the portion where the second threaded seat 53 is connected to the connecting ear 52 will deform and press downward, applying a downward pressure to the connecting ear 52, thereby tightening the connecting ear 52, and thus the laser ranging module 5 is fastened in the housing 1.

[0033] It should be noted that, in the present embodiment, the second threaded seat 53 is arranged on the outside of the connecting ear 52. When the safety screw 64 is tightened, when the second threaded seat 53 is raised, only the portion where the second threaded seat 53 is connected to the connecting ear 52 will be deformed to press the connecting ear 52 downward, while the main body in the middle of the laser ranging module 5 is pre-tightened by the adjusting screw 61 and will not be affected and deformed, thereby affecting the horizontality of the laser ranging module 5.

[0034] Continue to refer to Figure 2 In a specific embodiment provided herein, the laser ranging module 5 has a plurality of adjustment ends 51 spaced apart along the circumference. The laser ranging module 5 is secured within the housing 1 via a plurality of displacement adjustment assemblies 6 for the plurality of adjustment ends 51. In this embodiment, the laser ranging module 5 has three adjustment ends 51 spaced apart along the circumference.

[0035] Those skilled in the art will appreciate that, in other embodiments, the laser ranging module may also be provided with at least one fixed end (not shown) in the circumferential direction. The laser ranging module is secured within the housing by the cooperation of the at least one fixed end and the at least one adjustable end. The fixed end may be secured by screws or other fixing methods, which are not limited herein.

[0036] In summary, the working principle of the laser calibration structure of this application is as follows:

[0037] When the laser ranging module 5 and the zoom lens module 2 deviate and cannot remain parallel, first adjust the different locking depths by adjusting the screw 61. The laser ranging module 5 will be displaced in the vertical direction under the action of the elastic connector 62, thereby calibrating the laser ranging module 5 to a state parallel to the zoom lens module 2. After the adjustment is completed, tighten the safety screw 64. The second threaded seat 53 will move vertically upward relative to the safety screw 64 and be raised. The part where the second threaded seat 53 is connected to the connecting ear 52 will deform and press downward, applying a downward force to the connecting ear 52, thereby tightening the connecting ear 52, and thus fastening the laser ranging module 5 in the housing 1. The present application solves the technical problem of large measurement deviation of the drone pod laser ranging module 5 through a simple laser calibration structure.

[0038] According to a second aspect of the present application, a pod is further provided, comprising the laser calibration structure according to the first aspect.

[0039] According to a third aspect of the present application, a drone is also proposed, comprising the pod according to the second aspect above.

In this way, if these modifications and changes are within the scope of the claims of the present application and their equivalents, the present application is also intended to cover these modifications and changes. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims. The simple fact that certain measures are recited in mutually different dependent claims does not indicate that the combination of these measures cannot be used to advantage. Any reference signs in the claims should not be considered as limiting the scope.
