DETAILED DESCRIPTION
[0028] The technical solutions of the present application will be described clearly and completely in combination with the embodiments below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application.
[0029] Embodiment one: the window breaking action of the window breaker. Since the commonly used automobile glass is mainly safety glass (laminated glass), the actual force acting on the glass is wasted due to the existence of the reaction force and the "absorption" process of the kinetic energy of the impact of the punch structure on the glass in the moment of the impact of the punch structure on the glass. The following technical solution is proposed.
[0030] Reference Figures 1 to 6 The automobile window breaker with a stress recovery mechanism in the embodiment comprises a sleeve 1 and a driving gear set 5. The driving punch 6 is slidingly installed along the length direction of the sleeve 1. The driving punch 6 is provided with a driving rod 8 and a window breaking punch 7 at both ends. The high-strength spring 4 is arranged on the inner wall of one side of the sleeve 1 corresponding to the outer wall of the middle part of the driving punch 6.
[0031] The outer wall position of the driving punch 6 is provided with a gear groove corresponding to the driving gear set 5. The built-in cylinder sleeve 9 corresponding to the window breaking punch 7 is installed on the driving rod 8. The passive punch 13 is slidingly installed in the inner part of the built-in cylinder sleeve 9 corresponding to the window breaking punch 7. The pressure punch 12 corresponding to the passive punch 13 is slidingly installed in the built-in cylinder sleeve 9. The driving gear set 5 is arranged on the sleeve 1, and the driving gear set 5 is engaged with the gear groove on the driving punch 6. The first limiting assembly 16 is arranged at the intersection position of the driving rod 8 and the driving punch 6, and the driving rod 8 and the driving punch 6 maintain directional sliding action. The driving rod 8 is provided with the pawl block 2 at one end position corresponding to the outer part of the sleeve 1. The outer wall position of the driving punch 6 corresponding to the gear groove is provided with the air slot 601 corresponding to the length direction of the sleeve 1. The width of the air slot 601 is greater than the thickness of the driving gear set 5.
[0032] Basic principle: the window breaking mode proposed in the present application is basically similar to the conventional window breaking principle. The driving punch 6 is driven to move along the direction close to the high-strength spring 4 by rotating the driving gear set 5, so that the high-strength spring 4 is compressed to the maximum and directly locks the driving gear set 5. The one end position of the sleeve 1 corresponding to the window breaking punch 7 is attached to the automobile window. In the process of rapid release of the driving punch 6, the window breaking punch 7 rapidly impacts the automobile window under the elastic potential energy of the high-strength spring 4 to achieve the window breaking effect. Figure 3Need to explain: drive punch 6 and window breaking punch 7 are not directly connected, and the sliding relationship is maintained, and the gap with enough length is left between the two, the purpose is to ensure that the window breaking punch 7 receives the reaction force generated by the impact of the window, and has enough distance to move reversely.
[0033] Embodiment two: the technical content in embodiment one is as follows:
[0034] The technology in embodiment one is as follows:
[0035] S1: first, drive punch 6 is driven by the pin block 2 to rotate in a certain direction, so that the gear groove is engaged with the driving gear set 5, so that the drive punch 6 moves along the left side, and the window breaking punch 7 does not move synchronously, and the driving gear set 5 is directly locked, and when the drive punch 6 is released, the driving gear set 5 does not need to be unlocked, but the pin block 2 is directly actuated, so that the empty slot 601 in the gear groove cooperates with the driving gear set 5, so that the drive punch 6 and the driving gear set 5 are not in meshing relationship, so that the drive punch 6 is quickly released under the action of the elastic potential energy of the high-strength spring 4, and it needs to be explained that when the drive punch 6 moves along the right side, it will not be affected by the driving gear set 5, so as to ensure that the elastic potential energy is released to the maximum extent;
[0036] The first limiting assembly 16 provided in the present application is mainly used to maintain the sliding and limiting angle of the drive punch 6 and the drive rod 8;
[0037] S2: as shown in S1, when the drive punch 6 moves to the left side, the volume of the buffer bin one increases, but because there is repulsive force between the pressure punch 12 and the passive punch 13, the pressure punch 12 and the passive punch 13 are in a relatively stable state on the basis of maintaining the window breaking punch 7 relatively unchanged, but in the process of releasing the drive punch 6, the volume of the buffer bin one quickly decreases, and the gas in the buffer bin one is squeezed into the buffer bin two, which will cause the pressure punch 12 to move to the right side, but because the gas in the buffer bin one is compressed, it will also cause the window breaking punch 7 to move to the right side, and further, the movement trend of the window breaking punch 7 is higher than that of the pressure punch 12, so that the drive punch 6 and the window breaking punch 7 form a passive connection transmission form;
[0038] S3: It also needs to be explained that: in the process of driving the impact rod 6, first move the limiting pin 11 upwards, make the lower end of the limiting pin 11 thrust drive the impact rod 6, so as to ensure that the impact rod 6 releases the impact power to the greatest extent, but when the impact rod 6 moves to a certain distance under the action of the elastic potential energy of the high-strength spring 4, the limiting pin 11 is directly inserted into the impact rod 6, the purpose of which is to ensure that the maximum displacement distance of the impact rod 6 is further limited and positioned, so as to avoid the movement of the impact rod 6 when the breaking window punch 7 moves reversely, thereby reducing the reaction force generated by the car window under the influence of the high-strength spring 4, thereby maintaining the related values in the process of "recovery" of the reaction force.
[0039] Example three: supplementary explanation of stress recovery process in combination with example one and example two:
[0040] The pressure rod 12 is slidingly connected in the built-in air cylinder sleeve 9, and permanent magnets are installed at the positions of the pressure rod 12 and the passive impact rod 13 close to each other. The middle position of the driving rod 6 corresponding to the breaking window punch 7 and the driving rod 8 is set as a buffer chamber one, the inside position of the built-in air cylinder sleeve 9 corresponding to one end of the pressure rod 12 is set as a buffer chamber two, and an air vent is arranged between the buffer chamber one and the buffer chamber two. A small punch is arranged at the other end position of the passive impact rod 13, and the small punch is slidingly connected in the breaking window punch 7. A hitting cavity 15 is formed in the inside position of the breaking window punch 7 corresponding to the small punch, and a plurality of billiard balls 14 are arranged in the hitting cavity 15. The diameters of the billiard balls 14 are equal to the inner diameter of the hitting cavity 15. A second limiting assembly 17 is arranged at the intersection position of the driving impact rod 6 and the breaking window punch 7. An auxiliary sleeve 3 is installed on the outside wall position of the upper side of the sleeve 1. A limiting pin 11 is slidingly installed in the auxiliary sleeve 3 in the vertical direction. The limiting pin 11 penetrates the outer wall of the sleeve 1, the outer wall position of the driving impact rod 6 corresponding to the air slot 601, and the outer wall position of the breaking window punch 7 in sequence downwards, and an auxiliary spring 10 corresponding to the top end inner wall of the auxiliary sleeve 3 is installed on the limiting pin 11.
[0041] The following contents are set in combination with the related contents in example two:
[0042] S4: When the breaking window punch 7 receives the impact power of the driving impact rod 6 and hits the car window glass, the breaking window punch 7 directly bears the reaction force and shows a movement trend to the right side. In this process, first, multiple collisions between the plurality of billiard balls 14 in the hitting cavity 15 will occur, forming a multiple vibration process, and the passive impact rod 13 will also have a movement trend to the left side. However, the key content is that the whole breaking window punch 7 moves to the left side under the action of the reaction force.
[0043] S5: with the technical content in S4 for illustration: when the breaking window punch 7 moves to the left side direction, it will further cause the gas in the buffer bin one to be compressed and the gas inside to be squeezed into the buffer bin two, but as shown in embodiment two, because the overall driving punch rod 6 is locked by the limiting pin 11, the driving punch rod 6 will not move secondarily, so the gas in the buffer bin one is preferentially transferred to the buffer bin two, causing the pressure receiving punch 12 to move to the right side direction due to the change of gas pressure, and because the repulsive force is generated between the pressure receiving punch 12 and the passive punch 13, when the pressure receiving punch 1 moves to the right side direction, it will also cause the passive punch 13 to move to the right side direction, so that the small punch at the other end of the passive punch 13 impacts the breaking window punch 7 inside the position of the breaking window punch 7, the original power of the secondary impact action is still based on the elastic potential energy of the high-strength spring 4, but the difference is that: the power in the secondary impact action is mainly the reaction force generated by the car window on the breaking window punch 7, so that when the small punch impacts the breaking window punch 7, the breaking window punch 7 will further impact the car window glass on the basis of the original, but the impact force in the secondary impact action is much smaller than the impact force in the initial state, and when the small punch impacts the breaking window punch 7, it will also cause the billiard ball 14 to collide in the impact chamber 15, so it can be directly understood that: in the secondary impact process, because the breaking window punch 7 has completed the initial breaking window action, the secondary impact action is mainly a small amplitude breaking window through stress recovery, which not only ensures the breaking window effect but also avoids the accident caused by large breaking window force. The stress in the application mainly represents the reaction force generated by the car window glass on the breaking window punch 7 during the breaking window action.
[0044] In summary: the compression amount of the high-strength spring is used as the impact power, and when the driving punch rod is "released" instantaneously, it drives the breaking window punch to impact the window glass instantaneously to achieve the breaking window effect. Based on this, the transmission structure in the impact power release process is optimized and improved, specifically based on the pressure receiving punch and the passive punch, the essence is to use the reaction force generated by the car window on the breaking window punch during the breaking window to drive the pressure receiving punch to move axially secondarily, and the magnetic connection relationship between the pressure receiving punch and the passive punch is utilized to drive the passive punch to impact the breaking window punch secondarily. In the whole process, the secondary impact process of the breaking window punch is mainly used to optimize and enhance the breaking window, and simultaneously drive the directional movement of the billiard ball in the impact chamber. The key purpose is to "recover" the reaction force generated during the breaking window to enhance the breaking window effect.
