Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of drop apparatus, and particularly relates to a bionic blade type drop apparatus. BACKGROUND

[0002] The drop apparatus is roughly the same as the parachute in principle, and both are used to increase the air resistance area to offset a part of the gravity acceleration of the object to be dropped to achieve the purpose of deceleration and landing. In practical application, some specific environmental conditions and some dropping equipment (such as precision electrical equipment, optical mechanical equipment, etc.) have specific requirements, for example, the launch instrument must be launched with the upward surface after landing, and the working surface of the launch instrument must not be blocked by other things. Under such dropping requirements, if the launch instrument is directly thrown, it is difficult to ensure the certain orientation of the launch surface, and the launch instrument may be damaged and cannot be used after free falling from a certain height. If a traditional parachute is used to assist in dropping, it is difficult to ensure that the parachute will not block the launch surface after landing. Therefore, it is urgent to design a new type of drop apparatus which can better meet the dropping requirements of such equipment. SUMMARY

[0003] In view of the above problems, the present application provides a bionic blade type drop apparatus, which can ensure the orientation of the working surface of the dropping equipment and prevent the dropping equipment from being damaged when the dropping equipment falls from a high place regardless of the direction and force used during dropping.

[0004] In order to achieve the above purpose, the present application adopts the following technical scheme:

[0005] A bionic blade type drop apparatus, comprising a dropping equipment and a drop device for protecting the dropping equipment, the drop device comprising a drop apparatus main body and an equipment protection shell, the drop apparatus main body being in a flat structure of a blade shape, which helps to increase the wind resistance during the drop process, reduce the drop speed and reduce the landing impact force; a light-transmitting window body is embedded in the center position of the drop apparatus main body, the equipment protection shell being in a slot-shaped structure with an open top, the equipment protection shell being fixedly installed below the front surface of the light-transmitting window body of the drop apparatus main body, and the dropping equipment being arranged inside the equipment protection shell.

[0006] A plurality of downwardly inclined buffer landing frames are arranged in a ring shape at the edge of the drop apparatus main body, the upper end surface of each buffer landing frame being fixedly connected with the drop apparatus main body, and the height of the lower end surface of each buffer landing frame being lower than the height of the lower surface of the equipment protection shell; the overall center of gravity of the drop device and the dropping equipment is located below the center position of the back surface of the drop apparatus main body.

[0007] Further, the outer edges of the landing instrument body are provided with a plurality of sawtooth-shaped blade openings at intervals, which are used for preventing the landing instrument body from deviating from the intended landing site due to the influence of lateral wind, and can effectively resolve the lateral wind and avoid the deviation of the landing instrument during the landing process.

[0008] Further, the center of gravity of the landing device is located below the center of the back of the landing instrument body, and the center of gravity of the delivery equipment is located directly below the center of gravity of the landing device, and the two centers of gravity are coincided on a vertical line. Similar to the density distribution of plant leaves, the upper half is small and the lower half is large, which can better ensure the specific front and back orientation when falling.

[0009] Further, a light-transmitting window is provided at the center of the landing instrument body, and a light-transmitting window body made of transparent material is fixedly embedded in the light-transmitting window. Preferably, the light-transmitting window body is colorless transparent organic glass material, and the delivery equipment in the equipment protection shell can be clearly seen from the back of the light-transmitting window body, while ensuring that the normal work of the launching surface of the launching instrument is not affected.

[0010] Preferably, the landing instrument body is a planar plate made of carbon fiber material. Carbon fiber material has low density and high tensile strength, strong impact resistance, and very small weight, which is an ideal material for making landing instrument body.

[0011] Preferably, the equipment protection shell is made of magnesium alloy material, which has high material strength and is easy to make into a light and thin shell. It can be light and thin without deformation, and the density is relatively low, but slightly higher than that of carbon fiber.

[0012] Preferably, the buffer landing frame is made of aramid fiber material, and the back of the buffer landing frame is covered with a sealing cover plate. The number of buffer landing frames can be preferably set to more than three according to actual needs. When the landing instrument body falls from a high place, the buffer landing frame will first contact the ground and bear a strong impact force. The honeycomb core material has large structural strength and good impact resistance.

[0013] The application also includes other components that can be used normally, which are conventional means in the art. In addition, the devices or components not defined in the application, such as delivery equipment and honeycomb core material, all use existing technologies in the art.

[0014] The beneficial effects of the application are as follows:

[0015] The bionic blade type landing instrument can ensure the orientation of the working surface of the delivery device when the delivery device lands from high place, no matter what direction and force are used when the delivery device is delivered, and can ensure that the delivery device will not be damaged. Meanwhile, the landing instrument adopts the blade structure, can effectively utilize the wind resistance, reduce the landing speed, and the buffer landing frame of the blade type landing instrument adopts the honeycomb core material, can effectively buffer, and well ensures that the delivery device carried in the landing instrument is intact, and improves the safety of the delivered object.

[0023] The technical solutions of the present application will be described clearly and completely in combination with specific embodiments. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments.

[0024] It should be noted that the terms "upper", "lower", "front", "back", "inner", "outer" and the like indicate the orientation or positional relationship based on the drawings, and are only for convenience of description.

[0025] Embodiment 1

[0026] As Figures 1-5As shown, a bionic blade type descent device includes a delivery device 1 and a descent device for protecting the delivery device, the descent device including a descent device main body 2 and a device protection shell 3, the descent device main body being in a flat structure like a wide flat leaf, which helps to increase the wind resistance in the descent process, reduce the descent speed, and reduce the impact force on landing; a light-transmitting window 4 is embedded in the center of the descent device main body; the device protection shell is in a groove-shaped structure with an open top, and is fixedly installed below the front surface of the light-transmitting window of the descent device main body; and the delivery device is arranged inside the device protection shell.

[0027] Specifically, a light-transmitting window is provided in the center of the descent device main body, and a light-transmitting window body made of transparent material is fixedly embedded in the light-transmitting window. The light-transmitting window body is made of colorless transparent organic glass material with a light transmittance of greater than 92%, and the impact resistance is 16 times that of ordinary glass, the density is 1.05 g / cm 3 , and will not affect the normal work of the launch surface of the launch device.

[0028] Further, a plurality of sawtooth-shaped blade openings 5 are arranged at intervals on the outer edge of the descent device main body, which are used to prevent the descent device main body from deviating from the intended landing site due to the influence of lateral wind, and are similar to the sawtooth edges around the leaves of plants, which can effectively avoid the influence of lateral wind on the landing site.

[0029] A plurality of downwardly inclined buffer landing frames 6 are annularly arranged on the edge of the descent device main body, the upper end surface of each buffer landing frame is fixedly connected with the descent device main body, and the height of the lower end surface of each buffer landing frame is obviously lower than the height of the lower surface of the device protection shell. This design is to bear the impact of landing by the buffer landing frame, so that even if the buffer landing frame is damaged by a certain height due to the impact force, the ground will not hit the delivery device in the device protection shell, thereby ensuring the safety of the delivery device.

[0030] The overall center of gravity of the descent device and the delivery device is located below the center of the back surface of the descent device main body. The center of gravity of the descent device is located below the center of the back surface of the descent device main body, and the center of gravity of the delivery device is located directly below the center of gravity of the descent device, and the two centers of gravity coincide on a vertical line. Figure 7 As shown, the design concept of the bionic blade type descent device refers to the plant leaf, the front surface of the leaf, below the upper epidermis, is a dense and high-density palisade tissue; and the back surface of the leaf, above the lower epidermis, is a layer of loose and low-density sponge tissue. Due to the obvious difference in density between the front surface and the back surface of the leaf, the leaf always falls with the front surface downward and the back surface upward. The bionic blade type descent device refers to the density distribution of the plant leaf, and can better ensure that the front surface is always downward and the back surface is always upward when landing.

[0031] The landing instrument body is a plane board of carbon fiber material, mainly responsible for increasing wind resistance, carbon fiber material is light and elastic, density 1.5g / cm 3 And the tensile strength is generally above 3500Mpa, which is 7-9 times of steel material, with strong impact resistance, and the material itself is very small.

[0032] The device protection shell is made of magnesium alloy AZ91D material. The material has high strength, is easy to make into a light shell, can be light and thin without deformation, and has low density, density 1.82g / cm 3 But it is slightly higher than the density of carbon fiber, and the device fixed installation is on the bottom surface inside the device protection shell. According to the weight of the blade type landing instrument, the weight of the device in the protection sleeve is significantly greater than the weight of the blade type landing instrument. According to the center of gravity of each device, the installation positioning hole of the protection sleeve and the landing instrument is determined, and the assembly principle is to ensure that the center of gravity of the device and the center of gravity of the blade type landing instrument can coincide.

[0033] The honeycomb core material 7 of the buffer landing frame is made of aramid fiber material, and the back of the buffer landing frame is covered with a light plastic sealing cover plate 8 with a hexagonal shape, which is used to increase wind resistance; the front of the buffer landing frame is made of honeycomb aramid fiber Noxmex core material, with a density of 0.05g / cm 3 , used for weight reduction and increasing the impact resistance of the product. This kind of honeycomb core material is mainly used for weight reduction and impact resistance in aerospace, with strong impact resistance.

[0034] The buffer landing frame is provided with five, when the landing instrument body is thrown from 10-20 meters high, the buffer landing frame will first contact the ground, and support the landing instrument body, forming a structure similar to an overhead canopy, even if the landing occasionally has individual buffer landing frame tip damage, it will not affect the overall performance of the landing instrument body.

[0035] Example 2

[0036] As Figure 6As shown, the embodiment is only different from the embodiment 1 in that the overall structure of the bionic blade type landing device is designed according to circular symmetry, the landing device body is disc-shaped, a light-transmitting window is arranged at the center of the back of the landing device body, a device protection shell for placing the delivery device is arranged below the center of the front of the landing device body, and eight (or six, ten, etc.) triangular buffer landing frames are symmetrically arranged at equal intervals around the periphery of the landing device body. When the landing device body lands, the multiple buffer landing frames support the landing device body, and the delivery device in the device protection shell is well protected. The advantage of the landing device is that eccentric deviation is not easy to occur during the landing process, and the landing posture and landing orientation of the landing device body are better, but because the structural design requirement is relatively more strict, the production process needs to strictly ensure that the center of gravity of the delivery device and the landing device body (i.e. the center of the landing device body) is coincident, and the precision requirement of machining and assembly is relatively high, which increases the cost of the whole landing device. Therefore, the economy needs to be further improved.

[0037] The technical scheme of the present application is not limited to the above specific embodiments, and many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments. Any technical modification made within the spirit and principles of the present application falls within the protection scope of the present application.
