Description

Technical Field

[0001] This utility model relates to the field of glass breaking device technology, specifically to a glass breaking ball launcher for drones. Background Technology

[0002] Glass-breaking devices (also known as glass breakers or glass-breaking ball launchers) are specialized remote glass-breaking equipment used for throwing glass-breaking balls (or high-pressure balls). They are widely used in firefighting and rescue. Currently, glass-breaking devices have diverse structures and usage methods. For example, Chinese patent CN114209996B discloses a throwing-type glass-breaking system that can be installed on a high-pressure water cannon vehicle; Chinese patent CN221579515U discloses a manually activated glass breaker that can be used handheld; and Chinese patent CN211893653U discloses a pneumatic glass-breaking ball launching mechanism that can be mounted on a drone.

[0003] For glass-breaking devices used in different ways, targeted design and improvement are needed to make the glass-breaking devices more advantageous in specific scenarios. For example, for glass-breaking devices mounted on drones, it is usually necessary to reduce the weight and volume of the entire device as much as possible while ensuring structural strength, so as to reduce the load on the drone and the stability during operation. Chinese patent CN211893653U discloses a pneumatic glass-breaking ball launching mechanism, specifically configured with a guide tube, ball clamp, power chamber (air storage component), sealing mechanism, return spring, locking mechanism, and housing. The power chamber and sealing mechanism are mutually compatible, with the sealing mechanism movably located at one end of the power chamber for sealing and opening the power chamber. The locking mechanism is mutually compatible with the sealing mechanism for locking and unlocking the sealing mechanism. When the locking mechanism locks the sealing mechanism, the power chamber is closed, and the air pressure inside the power chamber can increase to the pressure required to launch the glass-breaking ball. When it is necessary to launch the glass-breaking ball, the locking mechanism unlocks the sealing mechanism. Under the action of the air pressure inside the power chamber, the sealing mechanism moves and releases the high-pressure gas inside the power chamber. The high-pressure gas acts on the glass-breaking ball, causing the glass-breaking ball to be launched through the guide tube under the action of air pressure, achieving the purpose of breaking the glass. This launch mechanism can be mounted on a drone to break glass. However, this is an early-generation product and has some shortcomings in practical applications. For example, 1. The structure is not compact and the size is large, resulting in high wind resistance and affecting the drone's flight control performance; 2. Because the entire shell cannot be molded as a single piece, it can only be connected by splicing, resulting in many connection points using fasteners. The large number of fasteners not only makes the overall weight greater and requires a drone with a larger load, but also makes the assembly process cumbersome and inefficient, which urgently needs to be addressed. Summary of the Invention

[0004] The first aspect of this utility model addresses the problems of existing launching mechanisms, such as non-compact structure, heavy weight, cumbersome assembly process, and low efficiency. It provides a launcher with a more compact structure and lighter weight, which not only facilitates assembly but also helps reduce the impact on the flight control performance of the UAV and ensures stability during operation. The main concept is as follows:

[0005] A glass-breaking ball launcher for a drone includes a housing with a first inner cavity and an upwardly protruding communication interface on its upper side, the upper end of which has a positioning plane; a base with a downwardly protruding boss on its lower surface, the base being detachably mounted to the communication interface, the lower surface of the boss abutting against the positioning plane and forming an annular groove between the positioning plane and the lower surface of the base; two protective covers with flanges at their lower ends that fit into the annular groove, the flanges engaging within the groove, the two protective covers being arranged opposite each other and fastened to the base with fasteners, forming a second inner cavity between the two protective covers; and a guide tube, a gas cylinder sleeve, and a ball clamp detachably connected to the housing, the gas cylinder sleeve accommodating a gas cylinder and the ball clamp storing glass-breaking balls. In this design, the transmitter is configured with six main load-bearing components: a housing, a base, protective covers, a guide tube, a gas cylinder sleeve, and a ball clamp. These components are detachably connected, allowing for modular design and facilitating manufacturing and efficient assembly. A downward-protruding boss is constructed on the lower surface of the base, its lower surface abutting against a positioning plane, forming an annular groove between the positioning plane and the lower surface of the base. This groove not only positions the protective cover but also suspends the base and housing below. Simultaneously, flanges fitting into the annular groove are constructed at the lower ends of the two protective covers. These flanges engage with the grooves, and the two protective covers are secured to the base with fasteners. This design not only results in a more compact structure but also facilitates rapid assembly of the protective covers. Furthermore, it improves the connection between the protective covers and the base, and between the protective covers and the housing. Eliminating the need for fasteners effectively reduces their number, thus lowering overall weight and size. A first inner cavity is constructed within the housing to house the valve core assembly, return spring, and locking mechanism. A second inner cavity is formed within the protective cover to house the power source and the transmission structure between the power source and the locking mechanism. This results in a more rational internal spatial layout for the launcher, leading to a more compact structure, smaller size, and easier positioning and assembly of other components. Compared to existing technologies, this launcher offers advantages such as a more compact structure, lighter weight, greater modularity, and easier assembly. This makes it more suitable for use on drones, reducing the load requirements on the drone, minimizing the impact on flight control performance, and promoting stable drone operation.

[0006] To achieve a detachable connection of the guide cylinder, preferably, a locking nut is also included. The front end of the housing is also provided with a first interface adapted to the guide cylinder, and an annular retaining ring is provided on the side of the guide cylinder. The rear end of the guide cylinder is inserted into the first interface, and the locking nut is threaded onto the first interface, pressing the annular retaining ring against the end of the first interface. This not only enables a detachable connection of the guide cylinder but also improves the connection strength between the guide cylinder and the housing, making the guide cylinder more robust.

[0007] Preferably, the lower side of the housing has a downwardly protruding second interface adapted to the ball clamp. The upper end of the ball clamp is inserted into the inner cavity through the second interface and locked to the second interface by a snap-fit ​​structure. By configuring the snap-fit ​​structure, it is easy to quickly install and remove the ball clamp, thus making it easier to use, especially to quickly replace the ball clamp and refill broken glass balls.

[0008] Preferably, the rear end of the housing is further provided with a third interface adapted to the gas cylinder sleeve, and the gas cylinder sleeve is threadedly connected to the third interface. The first interface and the third interface are located at opposite ends of the housing, which reduces the area of ​​the entire transmitter's windward surface and is more conducive to reducing wind resistance.

[0009] Preferably, the housing is a one-piece molded component. By configuring the housing as a one-piece molded component, not only can the structural strength be improved, but also no fasteners are required for assembly, which is beneficial for lighter weight and easier assembly.

[0010] Preferably, the shell is constructed in a cylindrical shape. This design is simple, easy to manufacture, helps reduce wind resistance, and is more suitable for drones.

[0011] To facilitate installation and disassembly of the base, preferably, the base has a through hole penetrating the upper surface of the base and the lower surface of the boss, and a threaded hole is constructed in the positioning plane, with the through hole corresponding to the threaded hole. The base is threadedly connected to the housing by fasteners that fit the threaded holes. This facilitates the installation and disassembly of the base.

[0012] Preferably, the communication interface is constructed as a long strip structure.

[0013] To further address the issues of improving assembly efficiency and accuracy, the lower surface of the boss is further constructed with a downwardly protruding plug, which is designed to fit into the communication interface for insertion. By inserting the plug into the communication interface and utilizing the plug-in engagement to position the mounting base, both assembly efficiency and accuracy can be improved.

[0014] Preferably, the positioning plane has two threaded holes, which are respectively located at both ends of the connecting interface.

[0015] Furthermore, the second inner cavity is also provided with a mounting bracket for installing a power source, which is detachably mounted on the base for installing the power source.

[0016] The second aspect of this utility model addresses the problem of easy mounting to the underside of a drone. Furthermore, it includes a quick-mount assembly comprising an upper mount and a lower mount that are mutually compatible. The lower mount has a rectangular opening at its lower end, with a pair of opposite sides of the rectangular opening each having a downwardly protruding hook. The upper end of the protective cover has a notch adapted to the hooks. The lower end of the lower mount abuts against the upper end of the protective cover, and the hooks are inserted into the notch and hook onto the edge of the notch. The rectangular opening communicates with a second inner cavity. The upper and lower mounts allow for quick and easy installation and removal of the transmitter from the drone. Furthermore, during assembly, the lower mount can be simultaneously secured to the two protective covers using fasteners. This ensures a rapid and secure connection between the lower mount and the protective covers, eliminating the need for any additional fasteners. This simplifies the assembly process, making it highly efficient and eliminating the need for additional fasteners or related structures, resulting in a simpler, more compact, and lighter design. Additionally, the rectangular opening connects the quick-assembly component's internal space to the second inner cavity, facilitating rapid assembly and wiring.

[0017] Furthermore, the lower mounting component has slides on both sides, and the upper mounting component has a groove adapted to the slides on its inner side. The lower mounting component can slide into and out of the upper mounting component through the cooperation of the slides and the groove.

[0018] The side of the lower mounting component is also provided with a locking hole, and the side of the upper mounting component is provided with a locking member that is adapted to the locking hole. The locking member is used to lock the lower mounting component.

[0019] The mounting hardware includes a connector for attaching the drone, allowing for the quick mounting of a glass-breaking ball launcher to the bottom of the drone, thus improving glass-breaking efficiency.

[0020] Preferably, the lower mounting component has an internal space, with a rectangular opening connected to the internal space. This facilitates faster wiring and assembly.

[0021] Furthermore, it also includes a power source, a trigger rod, a locking mechanism, a valve core assembly, and a return spring, all located in the second inner cavity. The power source is mounted on a mounting bracket, which is mounted on the base. The trigger rod is vertically movably mounted on the base, and the power source is connected to the trigger rod via a transmission connection. The locking mechanism includes a locking rod and a tension spring. The locking rod is located in the first inner cavity and hinged to the base via a hinge hole. One end of the locking rod is connected to the trigger rod, and the other end has a lock head. The valve core assembly includes a gas storage component located in the housing, a sealing mechanism movably located at the front end of the gas storage component, and a connector located at the rear end of the gas storage component. The front end of the sealing mechanism corresponds to the vent of the ball clamp, and the connector is used to connect to the gas cylinder. The return spring is sleeved on the outside of the sealing mechanism to drive the sealing mechanism to reset. The sealing mechanism has a slot adapted to the lock head. Initially, the lock head of the locking rod is locked in the slot under the action of the tension spring. The layout is more reasonable, making the structure more compact.

[0022] Compared with existing technologies, the glass-breaking ball launcher for drones provided by this utility model has advantages such as more compact structure, lighter weight, more modularity, and easier assembly, making it more suitable for use on drones. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0048] Example 1

[0049] This embodiment provides a glass-breaking ball launcher for drones, including a housing 1, a base 2, two protective covers 3, a guide tube 4, a gas cylinder sleeve 5, and a ball clamp 6, etc.

[0050] like Figure 1 As shown, the housing 1 has a first inner cavity 11, which is at least used to accommodate the valve core assembly. In practice, the housing 1 is preferably constructed as a cylindrical structure, which is simple in structure, easy to process and form, makes the structure more compact, and helps to reduce wind resistance, making it more suitable for UAVs. In this embodiment, the housing 1 is preferably made of a one-piece molded component, which not only improves the structural strength, but also eliminates the need for fasteners 52 for assembly, resulting in lighter weight and easier assembly.

[0051] like Figure 1 As shown, the upper side of the housing 1 has an upwardly protruding communication interface 12, and the upper end of the communication interface 12 has a positioning plane 13. In implementation, the entire upper surface of the communication interface 12 can serve as the positioning plane 13. In implementation, the communication interface 12 can preferably be constructed as a long strip structure, such as... Figure 1 As shown, this makes the connecting interface 12 longer, facilitating the placement of the locking mechanism. To facilitate connection to the base 2, threaded holes 14 are constructed within the positioning plane 13. The number of threaded holes 14 can be determined according to actual needs, for example, such as... Figure 1 As shown, two threaded holes 14 are constructed in the positioning plane 13. The two threaded holes 14 are respectively constructed at both ends of the connecting interface 12 to more stably and reliably fix the base 2.

[0052] In this embodiment, the base 2 primarily serves a load-bearing function. The shape of the base 2 can be adapted to the communication interface 12 to close the communication interface 12. In implementation, the base 2 may include a support plate. In implementation, the lower surface of the base 2 has a downwardly protruding boss 21, such as... Figure 2 As shown; simultaneously, the base 2 is constructed with through holes 24 penetrating the upper surface of the base 2 and the lower surface of the boss 21. The position and number of through holes 24 are respectively adapted to the threaded holes 14, and the through holes 24 correspond to the threaded holes 14, so that the base 2 can be threadedly connected to the housing 1 by fasteners 52 adapted to the threaded holes 14, so as to install and remove the base 2. In implementation, the through holes 24 can preferably be countersunk holes. In this embodiment, the base 2 is constructed with two through holes 24 respectively adapted to two threaded holes 14.

[0053] During assembly, the base 2 can be detachably mounted to the communication interface 12 using fasteners 52 such as bolts or screws. The lower surface of the boss 21 abuts against the positioning plane 13, and a ring-shaped groove 25 can be formed between the positioning plane 13 and the lower surface of the base 2. Figure 3 As shown. Meanwhile, the lower end of the protective cover 3 is constructed with a flange 31 that adapts to the annular groove 25, as... Figure 6 As shown, the flange 31 of the protective cover 3 is engaged in the annular groove 25. The two protective covers 3 are arranged opposite each other and can be fastened to the base 2 by fasteners 52, so that the two protective covers 3 and the base 2 can be connected as a whole. Figures 4-6 As shown, the two protective covers 3 can form a second inner cavity 32 to accommodate the installation of a power source 99 and a transmission structure for the phase-locking mechanism within the second inner cavity 32. In a more complete embodiment, the second inner cavity 32 also includes a mounting bracket 19 for installing the power source 99, such as... Figure 6 As shown, the mounting bracket 19 can be detachably mounted to the base 2 using fasteners 52 such as bolts or screws for mounting the power source 99. Furthermore, the base 2 can also be configured with a constraint cylinder 23 for guidance, such as... Figure 2 and Figure 3 As shown, the first inner cavity 11 and the second inner cavity 32 can be connected at least through the constraint cylinder 23.

[0054] In practice, one of the protective covers 3 has at least two through holes 24 on its side, and the other protective cover 3 has at least two threaded holes 14 that are adapted to each through hole 24 on its side. When the two protective covers 3 are spliced ​​together, each through hole 24 corresponds to each threaded hole 14, so that the two protective covers 3 can be held together by fasteners 52 such as bolts or screws that are adapted to the through holes 24 and threaded holes 14.

[0055] In a more refined embodiment, the lower surface of the boss 21 is provided with a downwardly protruding plug 22, such as... Figure 2 and Figure 6As shown, the plug 22 is configured to fit the communication interface 12, so that during assembly, the plug 22 can be inserted into the communication interface 12. By inserting the plug 22 into the communication interface 12, the installation position of the base 2 is positioned by using the plug 22 and the communication interface 12 to make the installation position of the base 2. This not only improves the assembly efficiency, but also improves the assembly accuracy.

[0056] In a more complete embodiment, the upper end of the protective cover 3 is also provided with a connecting part 34 for connecting the drone. The connecting part 34 may be a through hole 24, a threaded hole 14, etc., for assembly.

[0057] In this embodiment, the guide cylinder 4 is mainly used to guide the throwing of the glass ball, which helps to improve the throwing distance and throwing accuracy. In practice, the guide cylinder 4 is detachably connected to the front end of the housing 1 and communicates with the first inner cavity 11 so that the glass ball in the first cavity can be thrown out through the guide cylinder 4.

[0058] In implementation, the guide cylinder 4 can be threaded to the front end of the housing 1. In the preferred embodiment provided in this example, a locking nut 42 is also included, such as... Figure 5 and Figure 6 As shown, the front end of the housing 1 is also provided with a first interface 15 adapted to the guide cylinder 4, and the side of the guide cylinder 4 is provided with an annular retaining ring 41, as shown. Figure 6 As shown, during assembly, the rear end of the guide cylinder 4 is inserted into the first inner cavity 11 via the first interface 15. The outer side of the first interface 15 has external threads, allowing the locking nut 42 to be threaded onto the first interface 15 and press the annular retaining ring 41 against the end of the first interface 15. Figure 6 As shown, this not only enables the detachable connection of the guide cylinder 4, but also helps to improve the connection strength between the guide cylinder 4 and the housing 1, making the guide cylinder 4 more reliable.

[0059] In this embodiment, the main function of the gas cylinder sleeve 5 is to house the gas cylinder 51, such as... Figure 5 and Figure 6 As shown, the gas cylinder 51 stores high-pressure gas for throwing glass-breaking balls. In practice, the gas cylinder sleeve 5 is detachably connected to the rear end of the housing 1 and communicates with the first inner cavity 11 to facilitate quick installation and replacement of the gas cylinder, thereby improving efficiency.

[0060] In implementation, the rear end of the housing 1 is also provided with a third interface 16 adapted to the gas cylinder sleeve 5. The outer surface of the third interface 16 is provided with external threads adapted to the gas cylinder sleeve 5. This not only allows the gas cylinder sleeve 5 to be threadedly connected to the third interface 16, but also allows the gas cylinder inside the gas cylinder sleeve 5 to be pressed tightly by rotation, so as to achieve a more sealed connection between the gas cylinder and the valve core assembly. In implementation, the gas cylinder sleeve 5 can be implemented using existing technologies, which will not be described in detail here.

[0061] In this embodiment, the ball clamp 6 is mainly used to store broken glass balls and supply broken glass balls into the guide cylinder 4; the ball clamp 6 is detachably connected to the lower side of the housing 1 and communicates with the first inner cavity 11 so as to quickly replace the ball clamp 6 or replenish broken glass balls into the ball clamp 6.

[0062] In implementation, the lower side of the housing 1 has a downwardly protruding second interface 17 that adapts to the ball clamp 6, such as... Figure 1 and Figure 6 As shown, the upper end of the ball clip 6 is inserted into the inner cavity through the second interface 17 and locked to the second interface 17 by a snap-fit ​​structure, which makes it very convenient to quickly install and remove the ball clip 6, thus making it easier to use, especially to quickly replace the ball clip 6 and refill broken glass balls.

[0063] like Figure 6 As shown, the upper end of the ball clamp 6 has corresponding ball outlet and vent 63 on both sides. The ball outlet corresponds to the vent 63, as shown in the figure. The ball outlet is mainly used to allow the glass breaker to leave the ball clamp 6 under the action of air pressure so that it can enter the guide tube 4. The vent 63 is mainly used to connect the valve core assembly so that high-pressure gas can be connected through the valve core assembly. In practice, the vent 63 can be directly opposite the ball outlet. The shape of the vent 63 can be the same as or different from the ball outlet.

[0064] In implementation, the ball clamp 6 can be an existing ball clamp 6. However, in this embodiment, the ball clamp 6 has a cavity for storing broken glass balls. The ball clamp 6 can preferably be constructed as a cylindrical structure, such as... Figure 5 and Figure 6 As shown, multiple broken glass spheres can be stored in a stacked manner within the cavity. For example, in this embodiment, the sphere holder 6 includes a sphere box 61, a sphere support for supporting the broken glass spheres, an elastic element for supporting the sphere support, and an end cap 62, as shown. Figure 5 As shown, the upper end of the ball box 61 is closed, the ball outlet and the vent 63 are respectively constructed on the side of the upper end of the ball box 61, and the end cap 62 is threaded to the lower end of the ball box 61. The ball box 61 and the end cap 62 form the cavity. In implementation, the elastic element can preferably be a spring 87, so that the elastic element can be used to press the broken glass balls stored in the cavity upward, so that after the uppermost broken glass ball is thrown out, the broken glass balls located in the lower layer can automatically rise to the top for the next throw.

[0065] In this embodiment, as Figure 6 As shown, the ball clamp 6 and the guide cylinder 4 are perpendicular to each other. When the ball clamp 6 is inserted into the first inner cavity 11, the top of the ball clamp 6 can abut against the inner wall of the top of the first inner cavity 11, and the rear end of the guide cylinder 4 can abut against the side of the ball gate. The guide cylinder 4 can be directly facing the ball outlet on the side of the ball gate. Figure 6As shown, during implementation, the vent 63 can be directly opposite the ball outlet to reduce processing costs.

[0066] In implementation, the snap-fit ​​structure can be achieved using existing technology. However, in the preferred embodiment provided in this example, the snap-fit ​​structure includes a spring 87, a locking rod 8, a cover component 85, a slide 86 constructed on the inner sidewall of the second interface 17, and a mounting hole 18 connected to and perpendicular to the slide 86. Figures 6-9 As shown, correspondingly, the side of the ball clamp 6 (e.g., ball box 61) is provided with a slider 64. During the process of inserting the ball clamp 6 into the second interface 17, the slider 64 moves along the slide rail 86; the locking rod 8 is provided with a limiting step 81, and one side of the locking rod 8 is provided with a locking block 82. One side of the locking block 82 is provided with a guide surface 83, and the side opposite to the guide surface 83 is a limiting surface 84. The limiting surface 84 can be constructed as a vertical plane to limit the slider 64, such as... Figure 9 As shown; during assembly, the lower end of the locking rod 8 is positioned within the mounting hole 18, and the spring 87 is positioned at the bottom of the mounting hole 18 and supports the locking rod 8, as shown. Figure 9 As shown; the cover component 85 has an opening, and the cover component 85 can be fixed to the housing 1 by fastener 52. The limiting step 81 of the locking rod 8 abuts against the cover component 85 so as to press the locking rod 8 with the cover component 85. The upper end of the locking rod 8 extends out of the cover component 85 through the opening, as shown. Figure 7 and Figure 9 As shown. Initially, the guide surface 83 corresponds to the slide rail 86, and the guide surface 83 faces the outside of the second interface 17, as shown. Figure 7 As shown, during the insertion of the ball clamp 6 into the second interface 17, the slider 64 can press against the guide surface 83. The guide surface 83 drives the locking rod 8 downwards and compresses the spring 87, allowing the slider 64 to smoothly pass through the locking block 82. The locking block 82 automatically resets after the slider 64 passes, locking the slider 64 and thus quickly locking the ball clamp 6. When it is necessary to remove the ball clamp 6, the locking rod 8 can be pressed downwards, driving it to move downwards and causing the locking block 82 to leave the slide rail 86, thereby releasing the limitation and constraint on the slider 64, allowing for quick unlocking of the ball clamp 6 and easier replacement.

[0067] In a more complete embodiment, it also includes a valve core assembly, a locking mechanism, a gas cylinder, a return spring 93, a power source 99, a trigger rod 97, etc. The locking mechanism includes a locking rod 94. The valve core assembly can be implemented using existing technology. For example, the valve core assembly includes a gas storage component 91 and a sealing mechanism 90 movably disposed in the gas storage component 91. The valve core assembly can be installed into the first inner cavity 11 of the housing 1 via the third interface 16. The rear end of the gas storage component 91 is provided with a connector 92 for connecting the gas cylinder. The connector 92 can be coaxial with the third interface 16. In use, the gas cylinder sleeve 5 can be threaded to the third interface 16 and press the gas cylinder tightly against the connector 92, so that the gas storage component 91 in the valve core assembly is in a state of communication with the gas cylinder. The return spring 93 is sleeved on the outside of the sealing mechanism 90 and is mainly used to drive the sealing mechanism 90 to reset. The valve core assembly (sealing mechanism 90) faces the vent 63, such as Figure 5 and Figure 6 As shown; the power source 99 can preferably be a servo motor, and the power source 99 can be installed on the mounting bracket 19. The trigger rod 97 is vertically movable and constrained by the constraint cylinder 23. The power source 99 can be driven to the trigger rod 97 via the connecting rod 98 to drive the trigger rod 97 to move vertically up and down. The locking rod 94 is located in the first inner cavity 11 and is hinged to the base 2 through the hinge hole 96. The trigger rod 97 is driven to the locking rod 94. A lock head 95 is provided on the end of the locking rod 94 away from the trigger rod 97. The trigger rod 97 uses the lever principle to raise or lower the lock head 95. The sealing mechanism 90 is constructed with a slot. Initially, the lock head 95 of the locking rod 94 is locked in the slot under the action of the tension spring 87, such as Figure 6 As shown, it serves to lock the sealing mechanism 90. When it is necessary to throw the broken glass ball, the power source 99 drives the locking rod 94 to rotate, causing the lock head 95 to disengage from the slot, thereby achieving the purpose of unlocking the sealing mechanism 90.

[0068] Of course, in a more complete implementation, it also includes a control module for controlling the power source 99, etc. For details, please refer to Chinese patent CN211893653U, which will not be elaborated here.

[0069] Example 2

[0070] To address the issue of more efficient mounting to the underside of a drone, the main difference between this embodiment and Embodiment 1 above is that the glass-breaking ball launcher provided in this embodiment also includes a quick-mount assembly. The quick-mount assembly includes an upper mounting component 71 and a lower mounting component 74 that are compatible with each other. In implementation, the quick-mount assembly can be implemented using existing technologies, and correspondingly, the upper mounting component 71 and the lower mounting component 74 can also be implemented using existing technologies.

[0071] In this embodiment, the lower mounting component 74 can be configured as a box-like structure. The lower end of the lower mounting component 74 has a rectangular opening 75, and a pair of opposite sides of the rectangular opening 75 are respectively provided with downwardly protruding hooks 76, such as... Figure 11 and Figure 12 As shown, an L-shaped structure is preferred; at the same time, the upper end of the protective cover 3 is constructed with a notch 33 that adapts to the hook 76, as shown. Figure 10 As shown; during assembly, the lower end of the lower mounting component 74 can abut against the upper end of the protective cover 3. Simultaneously, the hook 76 is inserted into the notch 33 and hooks the edge of the notch 33. In practice, while using the fastener 52 to hold the two protective covers 3, the lower mounting component 74 can be held simultaneously. This not only quickly achieves a secure connection between the lower mounting component 74 and the protective cover 3, but also eliminates the need for any fasteners 52 between the lower mounting component 74 and the protective cover 3, making it very simple and efficient. Furthermore, it eliminates the need for additional fasteners 52 and related structures to accommodate them, resulting in a simpler, more compact structure and lighter weight. Figure 13 As shown, the rectangular opening 75 is connected to the second inner cavity 32, so that the internal space 78 of the quick-assembly component and the second inner cavity 32 can be connected through the rectangular opening 75 and the second inner cavity 32, which makes assembly and wiring easier.

[0072] In a more refined embodiment, slides 77 are respectively constructed on both sides of the lower mounting member 74, such as... Figure 11 and Figure 12 As shown, the inner side of the upper mounting component 71 is constructed with a groove adapted to the slide table 77. The lower mounting component 74 can slide into and out of the upper mounting component 71 through the cooperation of the slide table 77 and the groove, thereby realizing the quick connection and quick separation of the lower mounting component 74 and the upper mounting component 71.

[0073] like Figure 11 and Figure 12 As shown, the side of the lower mounting member 74 is also provided with a locking hole. Correspondingly, the side of the upper mounting member 71 is provided with a locking member 73 that is adapted to the locking hole, so as to lock the lower mounting member 74 by means of the locking member 73. In practice, the locking member 73 can be a bolt, screw or indexing pin, etc.

[0074] like Figure 11 As shown, the upper mounting component 71 is equipped with a connecting part 34 for connecting to the drone, so as to quickly attach the glass-breaking ball launcher to the bottom of the drone and improve the glass-breaking efficiency. In implementation, the connecting part 34 can be a through hole 24, a threaded hole 14, etc.

[0075] In this embodiment, the lower mounting member 74 has an internal space 78, and a rectangular opening 75 communicates with the internal space 78, such as... Figure 12 and Figure 13As shown, this allows for the installation of circuit boards and other components in the internal space 78, facilitating faster wiring and assembly.

[0076] like Figure 13 As shown, in this embodiment, the lower mount 74 is mounted on the upper mount 71, the protective cover 3 is mounted on the lower mount 74, and the housing 1 and the base 2 are mounted on the protective cover 3. This not only allows for quick installation and removal of the transmitter on the UAV, but also greatly reduces the number of fasteners 52 and the related structures that adapt to the fasteners 52, which is conducive to making the entire generator structure more compact and more reasonable.

[0077] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
