Description

Technical Field

[0001] The utility model relates to a drone battery unit with an integrated snap-on structure. Background Art

[0002] A drone is an aircraft that can fly without direct human control. Drones can be operated autonomously by radio remote control or by a preset flight control system. Drones have a wide range of applications in both military and civilian fields.

[0003] From a technical perspective, drones are usually divided into fixed-wing drones and multi-rotor drones. Fixed-wing drones have strong carrying capacity and long range, but poor turning and hovering capabilities; multi-rotor drones have more flexible flight states, but poor carrying capacity and stability. Therefore, fixed-wing drones with vertical take-off and landing have begun to appear on the market.

[0004] However, the existing vertical take-off and landing fixed-wing drones have the following defects:

[0005] (1) For example, the battery unit is fixed inside the fuselage by a number of screws and screw holes during installation. However, the excessive number of screws and screw holes causes the fuselage to be riddled with holes, which may reduce the balance of the drone and affect its flight. Excessive number of screws and screw holes also increases the work time of the assemblers.

[0006] (2) The original fuselage did not have a corresponding connection structure for installing the auxiliary battery unit. As a result, even if the battery unit was fixed with screws, the screws would loosen due to the vibration generated by the drone flying in the air, making it difficult to fix the battery, thereby affecting the use of the drone;

[0007] (3) The original battery unit is not equipped with a corresponding protective shell. The battery unit is simply installed and fixed inside the drone. Although the battery can be fixed, the battery without a protective shell has certain safety hazards and is not easy to install. Utility Model Content

[0008] The utility model provides a drone battery unit with an integrated snap-in structure, which can effectively solve the above problems.

[0009] The utility model is achieved in this way:

[0010] A drone battery unit with an integrated snap-in structure, comprising:

[0011] A fuselage; a wing disposed on the fuselage, and a tail connected to the wing;

[0012] The protection mechanism includes: an upper frame, a side frame, a lower base and a protection frame formed by the lower frame, and is used to accommodate the battery for the drone, and the two sides of the lower frame are fixedly provided with a card plate;

[0013] The clamping mechanism comprises: a mounting seat body, a groove formed in the middle of the top end of the mounting seat body, a pivot seat and a movable groove arranged inside the groove, and a clamping plate connected to the pivot seat and the movable groove and capable of rebounding and resetting;

[0014] The connecting mechanism comprises: a strip-shaped connecting long plate composed of a first connecting segment, a second connecting segment and a third connecting segment, a connecting plug plate arranged at one end of the second connecting segment, and an upper clamping member and a lower clamping member symmetrically arranged on the first connecting segment and the second connecting segment;

[0015] When installing the battery, the lower base presses the clamping plate into the groove, and the clamping plates on both sides of the lower frame move with the protective frame and are inserted into the upper clamping member and the lower clamping member until the lower frame is fully inserted. The clamping plate is reset and abuts against the edge of the lower frame fixed in the protective frame to complete the battery installation.

[0016] As a further improvement, a connecting seat is symmetrically arranged at the top of the upper frame, and a lifting member is buckled on the connecting seat bracket; and a plurality of slots are formed on the upper frame and the side frame.

[0017] As a further improvement, a plurality of heat dissipation holes for dissipating heat from the bottom of the battery are formed on the lower base.

[0018] As a further improvement, a first rod and a second rod are symmetrically arranged on two side surfaces of the clamping plate and are used for being movably connected with the pivot seat and the movable groove.

[0019] As a further improvement, a plurality of first screw holes are opened on the mounting seat body, a connecting plate body is arranged between the mounting seat bodies, and a plurality of first strip grooves and second strip grooves are formed on the mounting seat body and the connecting plate body, so as to reduce the weight of the clamping mechanism.

[0020] As a further improvement, the abutting end of the clamping plate has an arc-shaped portion.

[0021] As a further improvement, the upper clamping member and the lower clamping member both have a first inclined portion and a second inclined portion for guiding the lower frame, and a second screw hole is provided on the upper clamping member and the lower clamping member.

[0022] As a further improvement, a reserved groove is formed on the third connecting section for quickly disassembling the protective mechanism.

[0023] The beneficial effects of the utility model are:

[0024] (1) The utility model adds a protective frame to the battery, so that the battery does not need to be connected to the inside of the drone through structures such as screws. On the one hand, it can prevent the screws and screw hole structures from affecting the balance of the drone. On the other hand, it can also improve the safety of the battery, prevent it from shaking, and improve stability. At the same time, the protective frame can be quickly connected to the connecting mechanism. The connecting mechanism can be used to initially fix the protective frame. Subsequently, the protective frame can be clamped using the clamping plate in the clamping mechanism to complete the final fixation, which is simple and quick. Furthermore, the protective frame, connection and clamping structure are designed with various weight reduction features, so that the body 1 can maintain balance and the drone will not be unbalanced due to weight reasons, further improving the safety and stability of the drone.

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0038] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] Reference Figure 1-6 As shown, a drone battery unit with an integrated snap-in structure includes a body 1; a wing 2 arranged on the body 1, and a tail 3 connected to the wing 2.

[0040] The protection mechanism 4 includes: an upper frame 40, a side frame 43, a lower base 45 and a protection frame formed by the lower frame 47, and is used to accommodate the battery for the drone, so as to facilitate the connection with the body 1. The two sides of the lower frame 47 are fixedly provided with a clamping plate 48; the top of the upper frame 40 is symmetrically provided with a connecting seat 41, and the connecting seat 41 bracket is buckled with a lifting member 42; a plurality of slots 44 are formed on the upper frame 40 and the side frame 43. Among them, the design of the slot 44 can be used as a reinforcement hole to improve the structural strength of the side frame by increasing the local rigidity. At the same time, the slot 44 can be used to guide the cables in and out of the box body, which helps to keep the interior clean and orderly. Moreover, the slot 44 can be used as a design element to increase the aesthetics of the protection frame. Moreover, the slot 44 can reduce the use of materials, thereby reducing the weight of the overall structure. Finally, the slot 44 can provide air circulation and help heat dissipation.

[0041] A plurality of heat dissipation holes 46 for dissipating heat from the bottom of the battery are formed on the lower base 45. The heat dissipation holes 46 can not only dissipate heat for the battery, but also can reduce the weight of the protection frame to the maximum extent, and can reduce the weight of the drone.

[0042] It should be noted that, compared with the original design, in this case, there is no need to fix the battery to the body 1 with screws, and the screw fixing structure is abandoned. This is because the original screw fixing structure needs to be equipped with a corresponding screw hole structure. Opening screw holes on the body 1 will obviously affect the aesthetics and stability of the body 1. In order to prevent the screws from passing through the screw holes, the body 1 needs to be thickened, but the thickened body 1 is also likely to cause the weight of the nose and tail of the body 1 to be inconsistent, which may change the aerodynamic characteristics of the drone, increase air resistance, affect the flight speed and maneuverability, and cause the body 1 to be unable to maintain a good balance. Therefore, in order to avoid the above situation, the protective frame provided in this case can fix the battery, and through the corresponding connection and clamping structure, a quick disassembly and assembly protective structure is formed. At the same time, the protective frame, connection and clamping structure have undergone various weight reduction designs, so that the body 1 can maintain balance and will not cause the drone to lose balance due to weight reasons.

[0043] Furthermore, the advantages of avoiding fixing the battery with screws and screw holes are: (1) there is no need to consider the pressure exerted by the screws on the battery; (2) the battery generates heat during the charging and discharging process, and there is no need to consider whether the installation of the screws will hinder the heat dissipation of the battery; and (3) there is no need to consider whether the screws will loosen after the drone encounters vibration during flight.

[0044] The clamping mechanism 5 includes: a mounting seat body 50, a groove 52 formed in the middle of the top end of the mounting seat body 50, a pivot seat 53 and a movable groove 54 arranged inside the groove 52, and a clamping plate 57 connected to the pivot seat 53 and the movable groove 54 and capable of rebounding and resetting; the first rod 59 and the second rod 510 are symmetrically arranged on both sides of the clamping plate 57, and are used for being movably connected to the pivot seat 53 and the movable groove 54; the abutting end of the clamping plate 57 has an arc portion 58.

[0045] Furthermore, a reset component is provided on the outer wall of the first rod 59, and the reset component is composed of a torsion spring and other structures (existing technology, which will not be described in detail here). The torsion spring is sleeved on the first rod 59, and the first rod 59 can be reset by rebounding through the torsion spring after being pressed down. Therefore, when the protective frame is connected to the connecting mechanism, the clamping plate 57 connected to the first rod 59 can abut against the edge of the lower frame in the fixed protective frame, thereby forming a complete installation and fixing structure, which is not only simple and quick, but also has higher stability of the battery.

[0046] A plurality of first screw holes 56 are formed on the mounting seat body 50 , and a connecting plate body 51 is disposed between the mounting seat bodies 50 . A plurality of first strip grooves 55 and second strip grooves 511 are formed on the mounting seat body 50 and the connecting plate body 51 , so as to reduce the weight of the clamping mechanism 5 .

[0047] The connecting mechanism 6 includes: a strip-shaped connecting long plate composed of a first connecting section 60, a second connecting section 61 and a third connecting section 67, a connecting plug plate 69 arranged at one end of the second connecting section 61, and an upper clamping member 63 and a lower clamping member 64 symmetrically arranged on the first connecting section 60 and the second connecting section 61; the upper clamping member 63 and the lower clamping member 64 both have a first inclined portion 65 and a second inclined portion 66 for guiding the lower frame 47, and a second screw hole 62 is opened on the upper clamping member 63 and the lower clamping member 64.

[0048] As an embodiment of the present case, the clamping end of the upper clamping member 63 and / or the lower clamping member 64 can be set as an elastic member, wherein the elastic member includes a spring and a clamping block, the clamping block is connected to the spring, and the elastic member is arranged inside the clamping end, when the clamping plate 48 enters the clamping end, the clamping block is pressed down by the spring, so that after the clamping plate 48 is fully inserted into the clamping end, the clamping block can be reset by using the compressible deformation characteristics of the spring, thereby ensuring that the clamping plate 48 can be more firmly fixed in the clamping end (the space between the upper clamping member 63 and the lower clamping member 64), further improving the stability of the protective frame.

[0049] A reserved groove 68 is formed on the third connecting section 67 for quick disassembly of the protective mechanism 4 .

[0050] Furthermore, a rubber strip (not shown in the figure) can be provided in the reserved groove 68 so as to make the rubber strip contact with the protective frame. The rubber strip is elastic and can act as a buffer for the protective frame, thereby further protecting the battery inside the protective frame.

[0051] Principle of the utility model:

[0052] When installing the battery, the upper frame 40, the side frame 43, the lower base 45 and the lower frame 47 are combined and spliced ​​in advance, and the battery is placed in the protective frame combined by the frame to protect and fix the battery. Subsequently, the protective frame for installing the battery is spliced ​​with the connecting long plate using the clamping plates 48 on both sides of the lower frame 47. The clamping plates 48 are clamped into the upper clamping members 63 and the lower clamping members 64 in the connecting long plate until the lower frame 47 is fully inserted. The clamping plate 57 is reset by the reset structure and abuts against the edge of the lower frame 47 in the fixed protective frame to complete the installation of the protective mechanism 4. When disassembling the protective mechanism 4, the two clamping plates 57 are pressed into the groove 52 by the reset structure, and the protective mechanism 4 is dragged out of the connecting long plate to complete the disassembly. This structure is simple and quick.

[0053] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
