[0037] Example

[0038] This embodiment aims to provide a glass breaker that can be used to physically attack a target person in a vehicle, forcing him or her to lose the ability to move, which is beneficial to improving the handling ability of security personnel and providing them with effective and reliable countermeasures.

[0039] like Figures 1 to 8 As shown, the glass breaker includes a glass breaking structure and a load releasing device. The glass breaking structure includes a shell 1 and a pointed head 2. The pointed head 2 is provided with a plurality of pointed heads 2. The pointed heads 2 protrude on the outer wall surface of the shell 1, and any two adjacent pointed heads 2 are spaced apart.

[0040] The pointed part 2 is used to break the car window glass. For example, in some embodiments, the material of the pointed part 2 is set to be a high-hardness material such as tungsten steel, diamond or ceramic, so that the glass can be directly broken at the moment when the entire glass breaker touches the glass. Preferably, the material hardness of the pointed part 2 is greater than 60HRC, and the part of the pointed part 2 that hits the glass is set to point contact, and the minimum contact area at the tip is less than 1 square millimeter.

[0041] In some embodiments, the pointed portion 2 is configured as a cone, a truncated cone structure, a pyramid or a truncated pyramid structure.

[0042] In this embodiment, if Figure 1 and Figure 2 As shown, a plurality of through holes 13 are provided on the shell 1, and any through hole 13 is arranged through the shell 1; the through hole 13 is used to connect the external atmospheric environment with the internal cavity of the shell 1, and the through hole 13 serves as a release hole for the agent. When the glass breaker breaks the glass, the internal agent is released from the inside, and the desired released action load is diffused to the outside by using the plurality of through holes 13.

[0043] In this embodiment, if Figure 4 and Figure 8 As shown, the load release device includes an excitation mechanism 3 and a load mechanism 4, which are installed in the shell 1, and the output side of the load mechanism 4 is connected to the through hole 13. The excitation mechanism 3 is used to excite the load mechanism 4 so that the load mechanism 4 can output the agent and diffuse it through the through hole 13 to release it to the outside.

[0044] The glass breaker provided in this embodiment uses the shell 1 as an installation base, and a plurality of pointed heads 2 are distributed on the outer wall of the shell 1. The through hole 13 provided on the shell 1 is connected to the output side of the load mechanism 4. The excitation mechanism 3 and the load mechanism 4 in the load release device are loaded inside the shell 1; the excitation mechanism 3 excites the load mechanism 4 to output the agent, so that the agent is diffused and released to the outside through the through hole 13; in the specific operation process, in an emergency situation, the security personnel can throw or launch the glass breaker to directly break the window with the pointed head 2, and use the released load to force the target person to lose the ability to move, so as to stop the target person's adverse behavior. In this way, the window breaking function and the load releasing function are concentrated in the glass breaker, which provides a way to directly hit the target person in the car through one operation, and provides an effective and reliable countermeasure for the security personnel to flexibly implement disposal according to the situation.

[0045] The glass breaker provided in this embodiment can be thrown or launched by security personnel at a medium or long distance to break windows, thus avoiding the traditional situation of needing to make close contact with the car window.

[0046] In a specific embodiment, Figure 4 and Figure 8 As shown, there is an assembly cavity 14 in the housing 1, and the excitation mechanism 3 and the load mechanism 4 are detachably mounted in the assembly cavity 14. The output side of the load mechanism 4 is connected to the assembly cavity 14, and any through hole 13 is connected to the assembly cavity 14. On the one hand, the assembly cavity 14 serves to accommodate the installation load release device. On the other hand, when the load mechanism 4 initially releases the applied load, the applied load is first released in the assembly cavity 14, and then distributed by the assembly cavity 14 to each through hole 13 connected thereto, so that the applied load can be quickly diffused to the external atmospheric environment.

[0047] As a preferred embodiment, Figure 3 and Figure 7 As shown, the housing 1 includes a first body 11 and a second body 12 which are spliced ​​together. Concave cavities are respectively provided on the facing end surfaces of the first body 11 and the second body 12 to form an assembly cavity 14 in combination.

[0048] As a further embodiment, Figure 2 and Figure 4 As shown, a plurality of connecting posts 15 are provided in the shell 1, and connecting holes 16 are provided on the facing end surfaces of the first body 11 and the second body 12, respectively. The connecting posts 15 are used to plug into the connecting holes 16 on the first body 11 and the connecting holes 16 on the second body 12, so as to combine the first body 11 and the second body 12 to form the shell 1, and the connecting posts 15 and the assembly cavity 14 are arranged to avoid each other, and the connecting posts 15 are arranged in the outer area away from the center of the shell 1.

[0049] In a specific embodiment, the connecting column 15 is configured as a threaded column, and the connecting hole 16 is configured as a threaded hole; the first body 11 and the second body 12 are fixedly connected through the threaded connection between the multiple connecting columns 15 and the multiple connecting holes 16. This arrangement is conducive to the tight fixation of the first body 11 and the second body 12, maintaining a reliable connection foundation for the structure in the assembly cavity 14, and enhancing the integrity of the glass breaker.

[0050] Of course, the connection column 15 and the connection hole 16 can be inserted and fitted in an interference fit manner to fix the first body 11 and the second body 12 together.

[0051] In other embodiments, the first body 11 and the second body 12 can be configured as a threaded butt joint structure. This arrangement, a split-type design, makes overall assembly and disassembly convenient.

[0052] As a preferred embodiment, Figure 4 and Figure 8 As shown, the load release part also includes a safety mechanism 5, the safety end of the safety mechanism 5 is connected to the excitation mechanism 3, and the operating end of the safety mechanism 5 is arranged to extend through the outer wall of the shell 1. The safety mechanism 5 can ensure that the excitation mechanism 3 can be safely stored during the production, storage and transportation of the glass breaker.

[0053] In some embodiments, the safety mechanism 5 is configured as a safety pin, a safety bolt or a safety ring. The end of the safety mechanism 5 extending out of the shell 1 can be pulled by the user, and the end of the safety mechanism 5 extending into the shell 1 abuts against the excitation mechanism 3.

[0054] In a specific embodiment, the agent configured by the load mechanism 4 is set to at least one of tear gas, smoke agent and flash agent. Of course, the agent includes but is not limited to tear gas, smoke agent, flash agent, dye, etc., so that the glass breaker has the performance of tear gas bomb, smoke bomb, flash bomb, dye bomb.

[0055] In a specific embodiment, the excitation mechanism 3 is configured for electric excitation, gunpowder excitation or primer excitation; for example, the excitation mechanism 3 can be configured as a firing pin, a spring, a primer and a fuse wire. When the safety mechanism 5 is not activated, the firing pin is limited. After the safety mechanism 5 is activated, the firing pin is not restricted. Under the action of the spring, it strikes toward the primer and ignites the fuse wire on the primer. The fuse wire is connected to the agent configured by the load mechanism 4 to ignite the agent and achieve the purpose of releasing the action load. Among them, the fuse wire is configured as a slow-burning material to provide security personnel with sufficient time to aim and throw, and for the wave breaker to be thrown into the vehicle.

[0056] In a specific embodiment, the excitation mechanism 3 is equipped with a delayed trigger fuse. Specifically, the fuse is provided with a preset delay to ensure that the tear gas / smoke gas is detonated only after the glass is broken and thrown into the vehicle after being triggered.

[0057] In some embodiments, the excitation mechanism 3 is configured as acceleration-sensing excitation, and the fuse is triggered by the acceleration generated by the glass-breaking bomb hitting the glass, so as to ensure that the tear gas / smoke gas is accurately detonated after the glass is broken and the vehicle is entered.

[0058] For the design embodiment of the housing 1 structure:

[0059] For example, as an exemplary embodiment, Figures 1 to 5 As shown, the shell 1 is configured as a box structure, the box structure has one or more box layers, and the box layers are configured as a polyhedron structure, a polyhedron structure or a truncated cone structure; preferably, the box layers are configured as a regular polyhedron structure.

[0060] In a specific embodiment, the pointed portion 2 is arranged on the outer peripheral surface side of the box body layer and the end surface side of the box body layer facing away from the excitation mechanism 3 .

[0061] For example, the shell 1 is configured as four box body layers, and the shell 1 includes a first body 11 and a second body 12. The first body 11 is configured as two box body layers, and the second body 12 is configured as two box body layers; the two adjacent box body layers on the first body 11 and the second body 12 are configured as pyramid box body layers with a regular octagonal cross-section, and the pointed portion 2 is disposed in an area close to the edge to protrude from the outer peripheral surface of the box body layer. One or more pointed portions 2 are disposed on the outer peripheral surface of the box body layer, and the pointed portion 2 may also be disposed on the lateral end surface of the box body layer facing away from the excitation mechanism 3, for example, eight pointed portions 2 are disposed. The two box body layers spaced apart on the first body 11 and the second body 12 are configured as pyramid box body layers with a regular octagonal cross-section, and a plurality of pointed portions 2 are disposed on the lateral end surface of the pyramid box body layer facing away from the excitation mechanism 3, and the plurality of pointed portions 2 are disposed around the central axis of the pyramid box body layer, for example, eight pointed portions 2 are disposed. Preferably, the pointed portion 2 has an extension axis, and the extension axis is arranged perpendicular to the structural end face where the pointed portion 2 is located. Such arrangement of the pointed portion 2 is beneficial for the pointed portion 2 to always have at least one pointed portion 2 that can act on the target glass no matter how its posture changes after being thrown or launched with the shell 1, thereby ensuring the reliability of the glass breaking operation.

[0062] For example, two box body layers on the first body 11 may be respectively provided with through holes 13 , or the two box body layers may be jointly constructed to form the through hole 13 , wherein the safety mechanism 5 is arranged to avoid the through hole 13 .

[0063] For example, as another exemplary embodiment, Figures 6 to 8 As shown, the shell 1 is configured as a spherical structure, and at least one circle of pointed parts 2 is arranged around the outer circumferential wall surface of the spherical structure.

[0064] In a specific embodiment, the shell 1 is configured as a structure composed of two hemispheres. The shell 1 includes a first body 11 and a second body 12. The first body 11 is configured as one of the hemispheres, and the second body 12 is configured as the other hemisphere.

[0065] For example, the pointed portion 2 is wound around the outer circumferential wall surface formed by the first body 11 and the second body 12 ; of course, the pointed portion 2 can be wound around the outer circumferential wall surface of the first body 11 , and the pointed portion 2 can be wound around the outer circumferential wall surface of the second body 12 .

[0066] Preferably, the pointed portion 2 has an extension axis, and the extension axis is arranged to intersect with the center of the spherical structure; such arrangement and orientation of the pointed portion 2 is conducive to the pointed portion 2 being able to act on the target glass no matter how its posture changes after being thrown or launched with the shell 1, thereby ensuring the reliability of the glass breaking operation.

[0067] In the above description, the glass breaker is not limited to the application of breaking vehicle glass.

[0068] Compared with existing devices such as hand-thrown tear gas bombs and smoke bombs, one of the differentiating solutions of the present invention is that a pointed head 2 with high hardness and sharp appearance is installed on the shell 1, and its material is generally ceramic, diamond or tungsten steel, etc., and the distribution and orientation of the pointed head 2 ensure that after throwing or launching, no matter how its posture changes, there is always at least one pointed head 2 that can act on the target glass, providing sufficient pressure to break the tempered glass, so as to ensure that the shell 1 with a certain kinetic energy can smoothly pass through the broken glass, enter the car and release the internal load in time.

[0069] The device with glass breaking function involved in the present invention has the glass breaking function and can release effective loads, such as tear gas, smoke agent, flash agent, etc., after breaking and penetrating the glass, so as to effectively attack and stop targets in a car or indoors.

[0070] The present invention can provide public security and riot control personnel with an effective means of countering injuries caused by vehicles. The method is that through a single throw or launch, a load that can effectively prevent the vehicle driver from acting, such as tear gas, smoke agent, flash agent, etc., can be thrown into the vehicle while breaking the glass, so as to force the driver out, thereby forcing the vehicle to stop and stop the harmful behavior.

[0071] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
