Description

Technical Field

[0001] The present invention belongs to the technical field of window breakers, and in particular relates to an integrated window breaker. Background Art

[0002] A window breaker is an escape aid installed in enclosed spaces. It's typically placed in easily accessible locations within a car or other enclosed space. In emergencies like fire or drowning, it can be easily removed and used to break the glass windows and doors, allowing for a smooth escape.

[0003] Existing window breakers usually break car window glass by manually pushing the window breaking nail. The operating handle of this manual method is set outside the shell to facilitate the operator to perform the breaking operation. However, since the operating handle is exposed to the outside, it is easy to cause misoperation and accidentally hit the car window glass. For this reason, we designed an integrated window breaker. Summary of the Invention

[0004] In order to solve the problem in the prior art that car windows are easily hit by misoperation, the present invention aims to provide an integrated window breaker.

[0005] The technical solution adopted in the present invention is:

[0006] An integrated window breaker, comprising:

[0007] shell;

[0008] A pressing member is axially movably arranged on the housing, and a through hole is provided on the pressing member;

[0009] A window-breaking nail is provided in the housing and is connected to one end of the pressing member provided with a through hole;

[0010] and a protection switch movably disposed on the housing in an annular direction, wherein the protection switch is connected to a limiting member for passing through the through hole, and the limiting member is disposed in the housing;

[0011] Wherein, when the protection switch is circumferentially displaced to the open position of the protection switch, the limiting member is directly opposite to the through hole;

[0012] One end of the shell away from the pressing piece is provided with a window-breaking hole for the window-breaking nail to pass through.

[0013] The process of using the integrated window breaker of the above scheme is as follows: the integrated window breaker is installed on one side of the window glass and the window breaker nail is set toward the window glass. In normal state, the protection switch is circumferentially displaced to the off position of the protection switch (such as Figure 1As shown), at this time, the limiter is located on the axial front side of the pressing member to prevent the pressing member from being accidentally hit and causing the window glass to be accidentally hit; when it is necessary to manually break the window glass for escape, the protection switch can be circumferentially moved to the open position of the protection switch. At this time, the limiter is facing the through hole (as shown). Figure 2 As shown in the figure, the pressing part can be pressed or tapped forward toward the car window glass to drive the pressing part to move forward. During this process, the limiter passes through the through hole, and the limiter will not hinder the forward movement of the pressing part, thereby driving the window breaking nail to move forward and pass through the window breaking hole. The window breaking nail extends out of the shell and breaks the car window glass. The integrated window breaker can be used to manually break the car window glass, and the manual breaking mode has an anti-false triggering design, which is more reliable and stable.

[0014] Furthermore, an arc-shaped sliding groove is provided on the housing, and the protection switch is circumferentially slidably arranged on the arc-shaped sliding groove.

[0015] Furthermore, the housing is provided with a first identification body for identifying the open position, and the housing is also provided with a second identification body for identifying the closed position of the protection switch.

[0016] Furthermore, the number of the limiting members is two, and the number of the via holes is also two.

[0017] Furthermore, the window-breaking nail is connected to the pressing member via a driving mechanism;

[0018] The driving mechanism is used to drive the window breaking nail to extend out of the shell.

[0019] Furthermore, the driving mechanism is a gas generator, and the connection terminal of the gas generator extends out of the housing.

[0020] Furthermore, an annular gasket is provided at one end of the shell away from the pressing piece, and the inner diameter of the annular gasket is not less than the aperture of the broken window hole.

[0021] Furthermore, the inner diameter of the annular gasket is equal to the aperture of the broken window hole.

[0022] Furthermore, the annular gasket is connected to the housing via gasket bolts.

[0023] Furthermore, the integrated window breaker is mounted on one side of the vehicle window glass via a mounting base, wherein the mounting base includes a housing plate, a connecting plate and a mounting plate;

[0024] The housing plate is arranged on one side of the housing along the axial direction of the housing;

[0025] The housing plate is connected to the mounting plate via the connecting plate, and the mounting plate is provided with mounting holes for mounting and positioning;

[0026] The mounting plate is parallel to the housing plate.

[0027] The beneficial effects of the present invention are:

[0028] The use process of the integrated window breaker of this embodiment is as follows: the integrated window breaker is installed on one side of the window glass and the window breaker nail is set toward the window glass. In normal state, the protection switch is circumferentially displaced to the off position of the protection switch (such as Figure 1 As shown), at this time, the limiter is located on the axial front side of the pressing member to prevent the pressing member from being accidentally hit and causing the window glass to be accidentally hit; when it is necessary to manually break the window glass for escape, the protection switch can be circumferentially moved to the open position of the protection switch. At this time, the limiter is facing the through hole (as shown). Figure 2 As shown in the figure, the pressing part can be pressed or tapped forward toward the car window glass to drive the pressing part to move forward. During this process, the limiter passes through the through hole, and the limiter will not hinder the forward movement of the pressing part, thereby driving the window breaking nail to move forward and pass through the window breaking hole. The window breaking nail extends out of the shell and breaks the car window glass. The integrated window breaker can be used to manually break the car window glass, and the manual breaking mode has an anti-false triggering design, which is more reliable and stable.

[0040] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0041] Example 1:

[0042] like Figure 1-4 As shown, an integrated window breaker 10 includes a housing 11 , a pressing member 12 , a window breaking nail 13 and a protection switch 14 .

[0043] The pressing member 12 is axially movable on the housing 11 and is provided with a through hole 123. Specifically, one end of the pressing member 12 is a pressing end 121, and the other end is provided with the through hole 123. The pressing end 121 is preferably arc-shaped to facilitate pressing the pressing member 12. The pressing member 12 includes the pressing end 121 and a connecting section 122, which are connected to form a T-shaped structure. The through hole 123 is provided in the connecting section 122.

[0044] The window-breaking nail 13 is arranged in the shell 11. The window-breaking nail 13 is preferably axially arranged in the shell 11. The window-breaking nail 13 is connected to one end of the pressing piece 12 provided with a through hole, that is, the window-breaking nail 13 is connected to the other end of the pressing piece 12, that is, the window-breaking nail 13 is connected to the connecting section 122; the pressing piece 12 can be pressed to drive the window-breaking nail 13 to be pressed.

[0045] The protection switch 14 is circumferentially movable on the housing 11. A stopper 143 is connected to the protection switch 14 and is configured to pass through the through hole 123. The stopper 143 is disposed within the housing 11. When the protection switch 14 is circumferentially displaced to the open position 141, the stopper 143 faces the through hole 123. In a normal state, the stopper 143 blocks the front side of the pressing member 12, preventing the pressing member 12 from pressing forward, thereby preventing accidental tapping of the pressing member 12 and causing accidental impact on the vehicle window.

[0046] The end of the housing 11 away from the pressing member is provided with a window-breaking hole 111 (such as Figure 4 The use process of the integrated window breaker of this embodiment is as follows: the integrated window breaker is installed on one side of the window glass and the window breaker nail 13 is set toward the window glass. In normal state, the protection switch 14 is circumferentially displaced to the closing position 142 of the protection switch 14 (as shown in FIG. Figure 1 As shown), at this time, the limiting member 143 is arranged on the axial front side of the pressing member 12 to prevent the pressing member 12 from being accidentally hit and causing the window glass to be accidentally hit; when it is necessary to manually break the window glass for escape, the protection switch 14 can be circumferentially displaced to the open position 141 of the protection switch 14. At this time, the limiting member 143 is facing the through hole 123 (as shown). Figure 2As shown, the pressing member 12 can be pressed or tapped forward toward the vehicle window glass, driving the pressing member 12 forward. During this process, the stopper 143 passes through the through hole 123, and the stopper 143 does not hinder the forward movement of the pressing member 12. This in turn drives the window breaker 13 forward through the window breaking hole 111. The window breaker 13 extends out of the housing 11 and breaks the vehicle window glass. This integrated window breaker can be used to manually break vehicle window glass, and this manual breaking mode has an anti-accidental triggering design, which is more reliable and stable.

[0047] The housing 11 is made of a full metal housing, which is dustproof, waterproof, flame-retardant, strong and durable.

[0048] Example 2:

[0049] On the basis of embodiment 1, in this embodiment, the housing 11 is provided with an arcuate slot 112, and the protection switch 14 is circumferentially slidably arranged on the arcuate slot 112. The opening position 141 and the closing position 142 of the protection switch 14 are respectively the inner walls at both ends of the arcuate slot 112. Figure 1 As shown, the protection switch 14 is close to the inner wall of one end of the arc-shaped chute 112, and the inner wall of one end of the arc-shaped chute 112 is the closing position 142 of the protection switch 14; Figure 2 As shown, the protection switch 14 is close to the inner wall of the other end of the arc-shaped sliding groove 112, and the inner wall of the other end of the arc-shaped sliding groove 112 is the opening 141 of the protection switch 14.

[0050] It is best to provide a first identification body on the shell 11 for identifying the open position 141, the first identification body is the word "open", and the shell is also provided with a second identification body for identifying the closed position of the protection switch, the second identification body is the word "off", so as to facilitate the switch operation at a glance.

[0051] Example 3:

[0052] On the basis of Example 1, in this embodiment, the number of the limiting members 143 is two, the number of the through holes 123 is also two, and in normal state, the protection switch 14 is circumferentially displaced to the closing position 142 of the protection switch 14 (such as Figure 1 As shown), at this time, the two limiting members 143 are arranged on the axial front side of the pressing member 12 to better prevent the pressing member 12 from being accidentally hit and causing the window glass to be accidentally hit; when it is necessary to manually break the window glass for escape, the protection switch 14 can be circumferentially moved to the open position 141 of the protection switch 14. At this time, the two limiting members 143 are correspondingly facing the two through holes 123 (as shown). Figure 2As shown, the pressing member 12 can be pressed or tapped forward toward the window glass, driving the pressing member 12 forward. During this process, the stopper 143 passes through the corresponding through-hole 123, and the stopper 143 does not hinder the forward movement of the pressing member 12. The window breaker 13 can then be driven forward through the window-breaking hole 111. The window breaker 13 extends out of the housing 11 and breaks the window glass. This integrated window breaker can be used to manually break the window glass, and this manual breaking mode has an anti-accidental triggering design (two stoppers 143 further prevent accidental triggering), which increases reliability and stability.

[0053] Example 4:

[0054] On the basis of Example 1, in this embodiment, the window breaking nail 13 is connected to the pressing member 12 through a driving mechanism, that is, the window breaking nail 13 is connected to the other end of the pressing member 12 through a driving mechanism; the operation process of manually breaking the car window glass can refer to the use process of the integrated window breaker in Example 1, which will not be repeated here. The following mainly describes breaking the car window glass in another way.

[0055] The driving mechanism is used to drive the window-breaking nail 13 to extend out of the shell 11. In this embodiment, the driving mechanism is a gas generator 15. The terminal 151 of the gas generator 15 extends out of the shell 11. The terminal 151 of the gas generator 15 can be externally connected to an electric switch and a power supply. The specific process of breaking the car window glass in another way is as follows: starting the electric switch can energize the gas generator 15, and the gas generator 15 generates compressed gas to push the window-breaking nail 13 to extend out of the shell 11, thereby breaking the car window glass (the working principle of the gas generator can refer to the working principle of the gas generator in the prior art, such as the utility model with authorization number ZL201521013543.3 and patent name of manual and automatic window breaker using gas generator as source power, which has an introduction to the working process of the gas generator and will not be repeated here). Another way is the electric way.

[0056] The integrated window breaker 10 in this embodiment is a structure in which electric and manual designs are integrated, and the electric mode or the manual mode can be selected according to needs.

[0057] Example 5:

[0058] In this embodiment, based on Example 1, an annular gasket 113 is provided on the end of the housing 11 away from the pressing member 12. The inner diameter of the annular gasket is no less than the diameter of the window-breaking hole. When using the integrated window breaker, it must be mounted on the side of the vehicle window glass, with the window-breaking nail 13 facing the window glass. The end of the housing away from the pressing member must be placed close to the window glass, ensuring that the window-breaking nail 13 is perpendicular to the window glass, making it easier to break the window glass with the nail 13. However, the housing 11 is made of metal, which is not friendly to the window glass and can easily damage the window glass during driving. Therefore, the annular gasket provides a cushioning and shock-absorbing effect, better protecting the window glass.

[0059] In this embodiment, the inner diameter of the annular gasket 113 is equal to the aperture of the window-breaking hole 111 , so that the window-breaking nail 13 can pass through the annular gasket 113 to break the vehicle window glass.

[0060] The annular gasket 113 is connected to the housing 11 via gasket bolts 114. Figure 4 As shown, the annular gasket 113 is connected to the housing 11 through three gasket bolts 114 , so that the annular gasket 113 can be fastened to the housing 11 .

[0061] Example 6:

[0062] On the basis of Example 1, in this embodiment, the integrated window breaker 10 is installed on one side of the vehicle window glass via a mounting base 20 , and the mounting base 20 includes a housing plate 21 , a connecting plate 22 and a mounting plate 23 .

[0063] The housing plate 21 is axially disposed on one side of the outer shell 11; the housing plate 21 is connected to the mounting plate 23 via the connecting plate 22. The mounting plate 23 is provided with mounting holes 231 for mounting and positioning. When the integrated window breaker 10 is in use, the window breaker nail 13 needs to be positioned toward the vehicle window glass. In this case, the outer shell 11 is positioned perpendicular to the vehicle window glass, and the housing plate 21 is also positioned perpendicular to the vehicle window glass. Furthermore, because the mounting plate 23 is parallel to the housing plate 21, the mounting plate 23 is also positioned perpendicular to the vehicle window glass. The vehicle window glass and the window beam are perpendicular to form an angle, facilitating the mounting plate 23 to be mounted parallel to and in close contact with the vehicle window beam. The mounting plate 23 can be mounted to the vehicle window beam using mounting bolts corresponding to the mounting holes 231. This allows the mounting base 20 to be mounted at the angle, and thus the integrated window breaker 10 to be mounted at the angle, with the outer shell 11 positioned perpendicular to the vehicle window glass.

The above specific embodiments should not be construed as limiting the scope of protection of the present invention.
