[0026] Example 1

[0027] Reference Figures 1 to 5 , which is the first embodiment of the utility model, and provides a UAV chassis suitable for parking in mountainous areas, including a connecting assembly 1, including a wing chassis 11, a threaded module 12, a connecting rod 13, a straightening module 14, and a buffer module 15. The threaded module 12 is arranged at the bottom end of the wing chassis 11, and the connecting rod 13 is arranged at the bottom end of the threaded module 12. The grip assembly 2 includes a ground claw plate 21, a barb module 22, a lifting module 23, and a friction module 24. The ground claw plate 21 is fixedly arranged at the bottom end of the connecting rod 13, the barb module 22 is arranged at the bottom end of the ground claw plate 21, and the lifting module 2 3 is arranged on the side of the connecting rod 13, and the connecting rod 1 is threadedly connected to the bottom of the wing chassis 11 through the threaded module 12. When the UAV descends in a mountainous area, the lifting module 23 moves up the righting module 14 when the UAV tilts, and the righting module 14 presses the buffer module 15 inward to drive the UAV to right itself. At the same time, when the UAV descends to the ground, the grounding claw plate 21 is close to the ground, so that the friction force between the grounding claw plate 21 and the ground is increased through the friction module 24. At the same time, the UAV relies on its own gravity to press down the hook module 22, so that the hook module 22 hooks the ground to prevent the UAV from tipping over.

[0028] Specifically, the threaded module 12 includes a threaded cavity 12a and a threaded column 12b. The threaded cavity 12a is opened at the bottom end of the wing chassis 11, and the threaded column 12b is threadedly connected to the inner side of the threaded cavity 12a. The upper end of the connecting rod 13 is fixedly connected to the threaded column 12b, and the threaded column 12b is threadedly connected to the threaded cavity 12a, so that the connecting rod 13 can be installed at the bottom end of the wing chassis 11.

[0029] Further, the straightening module 14 includes an intermediate column 14a, a tilting block 14b, a connecting block 14c, and a connecting frame 14d. The intermediate column 14a is fixedly arranged on the outside of the middle position of the connecting rod 13, the tilting block 14b is rotatably arranged at both ends of the intermediate column 14a, and the connecting frame 14d is connected to connect the connecting block 14c and the tilting block 14b. The buffer module 15 includes a buffer spring 15a, a buckle slot block 15b, a buckle block 15c, and an arc-shaped slider 15d. The buffer spring 15a is fixedly arranged on the upper end of the connecting block 14c, the buckle slot block 15b is arranged on the upper end of the intermediate column 14a, the buckle block 15c is buckled on the inner side of the buckle slot block 15b, and the buckle block 15c is fixedly arranged on the side of the arc-shaped slider 15d. The other end of the buffer spring 15a is arranged on the inner wall of the arc-shaped slider 15b. First, the arc-shaped slider 15d is connected to the bottom end of the UAV through the cooperation of the buckle block 15c and the buckle groove block 15b. At the same time, the connecting block 14c and the upper end of the tilting block 14b are connected together through the connecting frame 14d. When the UAV descends to the mountainous area, the lifting module 23 is in contact with the ground and is squeezed upward by the ground to drive the tilting block 14b to flip along the middle column 14a so that the tilting block 14b drives the connecting block 14c to rotate in an arc shape inside the arc-shaped slider 15d. When the connecting block 14c slides in an arc shape inside the arc-shaped slider 15d, it pushes the buffer spring 15a to straighten the UAV fuselage to prevent the UAV from tipping over.

[0030] Example 2

[0031] Reference Figures 1 to 5 As shown, it is a second embodiment of the utility model, which is different from the previous embodiment in that the barb module 22 includes a mounting post 22a, a barb spring 22b, a barb piece 22c, and a mounting frame 22d. The mounting post 22a is fixedly arranged at the bottom end of the grounding claw plate 21, the mounting frame 22d is fixedly arranged at the bottom end of the mounting post 22a, the barb piece 22c is movably arranged inside the mounting frame 22d, the barb piece 22c and the mounting frame 22d are connected by a hinge, the barb spring 22b is arranged between the barb pieces 22c, and at the same time When the UAV descends to the ground, the UAV's own gravity drives the mounting post 22a at the bottom of the wing chassis 11 to move downward and inserts the barb piece 22c at the bottom of the mounting post 22a into the ground. As the barb piece 22c penetrates into the ground, the connected barb pieces 22c come close to each other and squeeze the barb spring 22b. Then the barb spring 22b releases the stored force to push the barb piece 22c to expand to both ends, so that the barb piece 22c can support and squeeze its surrounding position under the ground, so that the UAV can grip the ground firmly and land smoothly.

[0032] Furthermore, the lifting module 23 includes a lifting slot 23a, a lifting rod 23b, a connecting platform 23c, a connecting block 23d, and a bottom notch 23e. The lifting slot 23a is arranged on the side of the connecting rod 13, and the bottom notch 23e is arranged on the bottom end of the connecting rod 13. The lifting rod 23b is slidably arranged inside the connecting rod 13. The connecting platform 23c passes through the lifting slot 23a and is arranged on the side of the lifting rod 23b. One end of the connecting block 23d is arranged on the inner side of the connecting platform 23c, and the other end of the connecting block 23d is arranged at the bottom end of the tilting block 14b. The friction module 24 includes a rubber block 24a and a rubber groove 24b. The rubber block 24a is fixedly arranged at the bottom end of the grounding claw plate 21. The block 24a is fixedly arranged on the outside of the mounting column 22a, and the rubber groove 24b is opened on the lower end surface of the rubber block 24a. When the UAV descends, the lifting rod 23b is squeezed by the ground and moves upward. During the process of the lifting rod 23b being squeezed by the ground and moving upward, the connecting platform 23c fixedly connected to the side end of the lifting rod 23b will connect to the connecting block 23d and move upward, so that the bottom end of the tilting block 14b is moved toward the outer upper end through the connecting block 23d to straighten the corresponding UAV. At the same time, when the UAV descends smoothly to the ground, the rubber block 24a at the bottom of the grounding claw plate 21 can cooperate with the rubber groove 24b to increase the friction between the UAV and the ground, making the parking of the UAV more stable.

[0033] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
