[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0024] This application discloses a landing gear device for a logistics delivery drone. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A landing gear device for a logistics delivery drone includes a body 1, a delivery box 3 fixedly connected to the bottom of the body 1, and support mechanisms 2 installed on both sides of the bottom of the body 1.
[0025] The support mechanism 2 includes a fixed base 201, the top of which is fixedly connected to the bottom of the body 1. A positioning groove 215 is provided at the bottom of the fixed base 201. A support frame 202 is engaged in the inner cavity of the positioning groove 215. A motor 211 is fixedly connected to the back side of the support frame 202. A rotating shaft 207 is fixedly connected to the output end of the motor 211. A rotating seat 209 is fixedly connected to the surface of the rotating shaft 207. A ventilation groove 208 is provided in the inner cavity of the rotating seat 209. A support plate 203 is fixedly connected to the bottom of the rotating seat 209.
[0026] Reference Figure 2 and Figure 4The bottom of the support plate 203 is provided with a fixing groove 212, and a buffer pad 204 is fixedly connected to the inner cavity of the fixing groove 212. The buffer pad 204 is made of rubber. By setting the buffer pad 204, the friction force received by the support plate 203 when in contact with the ground is increased, ensuring the stability of the support plate 203 when in contact with the ground. At the same time, the support plate 203, which is made of rubber, has high elasticity. When the aircraft 1 lands, it can absorb the impact energy through its own elastic deformation, thereby reducing the damage to the fuselage structure from direct impact and ensuring the smooth landing of the aircraft 1.
[0027] Reference Figure 2 The bottom of the buffer pad 204 is fixedly connected with protrusions 205. There are several protrusions 205 arranged in multiple rows and columns. By setting the protrusions 205, the roughness of the bottom of the support plate 203 can be increased, forming a physical interlock with the ground. At the same time, through the independent deformation of multiple protrusions 205, uneven areas of the ground can be automatically filled, ensuring that the support plate 203 as a whole is in full contact with the ground.
[0028] Reference Figure 4 and Figure 5 The bottom of the fixed base 201 is provided with a connecting groove 216, and a connecting plate 217 is inserted into the inner cavity of the connecting groove 216. A fixing plate 210 is fixedly connected to the bottom of the connecting plate 217. The top of the fixing plate 210 contacts the surfaces of the fixed base 201 and the support frame 202 respectively. The fixing plate 210 limits the support frame 202 and prevents the support frame 202 from detaching from the inside of the positioning groove 215 during use. When the fixing plate 210 is in place, the surface of the connecting plate 217 will engage with the inside of the connecting groove 216, thereby positioning the fixing plate 210 and preventing the fixing plate 210 from detaching from the bottom of the support frame 202 during use.
[0029] Reference Figure 4 and Figure 5Both the support frame 202 and the fixing plate 210 have fixing slots 218 inside their cavities. An elastic block 214 engages with the cavity of the fixing slot 218. The surface of the elastic block 214 is fixedly connected to the cavity of the positioning groove 215. The elastic block 214 is made of nylon. The fixing slots 218 allow the surface of the elastic block 214 to engage with the interior of the support frame 202 and the fixing plate 210, thus initially positioning the support frame 202 and ensuring its stable fit within the positioning groove 215. Simultaneously, the fixing plate 210 can be fixed... The position is reinforced to further improve the fixing effect of the fixing plate 210 and ensure the stable use of the fixing plate 210. The elastic block 214 made of nylon has the characteristics of environmental aging resistance, wear resistance, impact resistance and high tensile strength, ensuring the stability of the elastic block 214 during use, reducing the time required to disassemble the support frame 202, and avoiding the loosening that can easily occur during use when fixed with bolts. The nylon molecular chain structure is compact and achieves quick insertion through elastic deformation. The interlocking force is stable and there is no risk of loosening or falling off during use.
[0030] Reference Figure 4 and Figure 5 The top of the inner cavity of the support frame 202 and the fixing plate 210 is provided with a guide groove 219. A guide rod 213 is inserted into the inner cavity of the guide groove 219. One end of the guide rod 213 is fixedly connected to the inner cavity of the positioning groove 215. The guide rod 213 guides the movement of the support frame 202 and the fixing plate 210, ensuring that the support frame 202 and the fixing plate 210 can be stably attached to the surface of the fixing seat 201, and preventing the position of the support frame 202 and the fixing plate 210 from shifting during the movement, which would affect the subsequent normal positioning.
[0031] Reference Figure 3 and Figure 4 A protective cover 206 is fixedly connected to the surface of the motor 211. The front side of the protective cover 206 is fixedly connected to the back side of the support frame 202. The protective cover 206 is made of aluminum alloy. The protective cover 206 protects the surface of the motor 211. The protective cover 206, made of aluminum alloy, has excellent thermal conductivity, which can help the motor 211 dissipate heat. It also has the ability to prevent splashing, moisture and dust, and can adapt to various weather conditions to ensure the stable operation of the motor 211.
[0032] Working principle: Before landing, the aircraft 1 automatically observes the ground conditions through its camera. If the landing surface is uneven, the motor 211 is started by an external power source. The motor 211 drives the rotating shaft 207 to rotate, which in turn drives the rotating seat 209 to rotate. The rotation of the rotating seat 209 drives the support plate 203 to rotate, adjusting the angle of the support plate 203 to ensure that it is roughly in contact with the ground. The rotation of the support plate 203 drives the buffer pad 204 to rotate, allowing the buffer pad 204 to fit more stably against the ground, thus ensuring that the aircraft 1 can land stably on the ground.
[0033] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
