Description

Technical Field

[0001] The invention relates to the technical field of automobile window breakers, and in particular to an automobile window breaker adopting a stress recovery mechanism. Background Art

[0002] The car window breaker achieves the window breaking action based on instantaneous impact force. Its essence can be referred to the relevant content in the publication number CN106218576A. Specifically, it uses the elastic potential energy of the spring to "store" and "release" energy, and the window breaking force is proportional to the compression amount of the spring.

[0003] It should be noted that: during the window breaking process, the striker structure will be subjected to a reverse force when hitting the window. In this process, if the impact force is not enough, it will be difficult to achieve the window breaking effect. If the impact force is too great, it will also cause glass splashing and injuring people. Currently, car windows (windshields, sunroofs) are mostly made of shatterproof safety glass (laminated glass), which has a certain cushioning property. Therefore, when the striker structure hits quickly, on the one hand, because of the reaction force, on the other hand, the kinetic energy of the striker structure is "absorbed" due to the cushioning property, resulting in a certain degree of "waste" of the actual force acting on the glass, and the expected window breaking effect cannot be achieved.

[0004] This application proposes a solution to this problem. Summary of the invention

[0005] The purpose of the present invention is to provide a car window breaker with a stress recovery mechanism. Regarding the window breaking action of the window breaker, because commonly used car glass is mainly shatterproof safety glass (laminated glass), at the moment when the striker structure hits the glass, due to the existence of the reaction force and the glass "absorbing" the kinetic energy of the impact of the striker structure, the actual force acting on the glass is "wasted".

[0006] The object of the present invention can be achieved by the following technical scheme: an automobile window breaker adopting a stress recovery mechanism comprises a sleeve and a driving gear set, the sleeve is provided with a driving punch rod slidably mounted along its length direction, a driving rod and a window breaking punch are respectively provided at both ends of the driving punch rod, and a high-strength spring is provided at a position of the inner wall of one side of the sleeve corresponding to the outer wall of the middle part of the driving punch rod;

[0007] A gear groove corresponding to the active gear set is opened on the outer wall of the driving punch rod, a built-in air cylinder sleeve corresponding to the window breaking punch is installed on the driving rod, a passive punch rod is slidably installed in the internal position of the built-in air cylinder sleeve corresponding to the window breaking punch, and a pressure punch rod corresponding to the passive punch rod is slidably installed in the built-in air cylinder sleeve.

[0008] It is further configured that: the driving gear set is arranged on the sleeve, and the driving gear set is meshed with the gear groove on the driving punch rod.

[0009] It is further configured as follows: a first limit assembly is provided at the intersection of the driving rod and the driving punch, and a directional sliding action is maintained between the driving rod and the driving punch, and a pin block is installed at one end of the driving rod corresponding to the outside of the sleeve.

[0010] It is further configured as follows: an empty slot corresponding to the length direction of the sleeve is opened on the outer wall position of the driving punch corresponding to the gear slot, and the width of the empty slot is greater than the thickness of the driving gear set.

[0011] It is further configured as follows: the pressure-bearing punch rod is slidably connected in the built-in air cylinder sleeve, and permanent magnets are installed at the positions of the ends of the pressure-bearing punch rod and the passive punch rod that are close to each other.

[0012] It is further configured as follows: a middle position inside the driving punch rod corresponding to the window breaking punch and the driving rod is set as buffer bin one, an internal position of the built-in air cylinder sleeve corresponding to one end of the pressurized punch rod is set as buffer bin two, and a vent is provided between buffer bin one and buffer bin two.

[0013] It is further configured as follows: a small punch is arranged at the other end of the passive punch rod, and the small punch is slidably connected in the window breaking punch.

[0014] It is further configured as follows: an impact cavity is opened in an inner position on one side of the window breaking punch corresponding to the small punch, and a plurality of billiard balls are arranged in the impact cavity, and the diameter of the billiard balls is equal to the inner diameter of the impact cavity.

[0015] It is further configured as follows: a second limiting component is provided at the intersection of the driving punch rod and the window breaking punch.

[0016] It is further configured as follows: an auxiliary sleeve is installed on the upper outer wall of the sleeve, a limit pin is slidably installed in the auxiliary sleeve along the vertical direction, the limit pin penetrates downward through the outer wall of the sleeve, the outer wall position of the driving punch rod corresponding to the empty slot and the outer wall position of the window breaking punch, and an auxiliary spring corresponding to the inner wall of the top end of the auxiliary sleeve is installed on the limit pin.

[0017] The present invention has the following beneficial effects:

[0018] 1. The overall structure is based on the conventional window-breaking principle. The elastic potential energy of the high-strength spring during compression is used as the impact power to drive the window-breaking punch to produce an instantaneous impact force on the car window during the instantaneous release process to achieve the window-breaking effect. The difference from the conventional window-breaking method is that: the transmission structure during the impact power release process is optimized and improved. Based on the compressed punch rod and the passive punch rod, the overall transmission process is not the operation mode of directly driving the window-breaking punch by the driving punch rod. Specifically, the window-breaking punch is driven by the air pressure conversion relationship and the magnetic connection relationship to directional impact the car glass to achieve the window-breaking effect.

[0019] 2. Based on the above content, the key to the overall process lies in the movement process of the compressed punch rod and the passive punch rod, and further limits the connection relationship between the driving punch rod and the active gear set. The purpose is to avoid a large-scale consumption of the impact force generated by the driving punch rod, and synchronously set a limit pin to limit the relative position of the driving punch rod after release, so that when the reaction force during the impact process is recovered, it is only reflected on the window breaking punch. In the process of air pressure conversion, the relative movement of the compressed punch rod and the passive punch rod is driven to ensure that the small punch in the passive punch rod performs a secondary impact on the window breaking punch, which is used to improve the purpose of enhancing the window breaking effect.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1: With regard to the window breaking action of the window breaker, since the commonly used automobile glass is mainly shatterproof safety glass (laminated glass), at the moment when the striker structure hits the glass, due to the existence of the reaction force and the glass "absorbing" the kinetic energy of the striker structure, the actual force acting on the glass is "wasted". The following technical solution is proposed:

[0030] Reference Figures 1 to 6 The automobile window breaker adopting the stress recovery mechanism in this embodiment comprises a sleeve 1 and a driving gear set 5. The sleeve 1 is provided with a driving punch rod 6 slidably mounted along its length direction. A driving rod 8 and a window breaking punch 7 are respectively provided at both ends of the driving punch rod 6. A high-strength spring 4 is provided at a position of the driving rod 8 corresponding to the inner wall of one side of the sleeve 1 and the outer wall of the middle part of the driving punch rod 6;

[0031] A gear groove corresponding to the active gear set 5 is provided on the outer wall of the driving punch rod 6, a built-in air cylinder sleeve 9 corresponding to the window breaking punch 7 is installed on the driving rod 8, a passive punch rod 13 is slidably installed in the internal position of the built-in air cylinder sleeve 9 corresponding to the window breaking punch 7, and a pressure punch rod 12 corresponding to the passive punch rod 13 is slidably installed in the built-in air cylinder sleeve 9, the active gear set 5 is arranged on the sleeve 1, and the active gear set 5 is meshed with the gear groove on the driving punch rod 6, a first limiting assembly 16 is provided at the intersection of the driving rod 8 and the driving punch rod 6, and a directional sliding action is maintained between the driving rod 8 and the driving punch rod 6, a pin block 2 is installed at one end of the driving rod 8 corresponding to the outside of the sleeve 1, and an empty groove 601 corresponding to the length direction of the sleeve 1 is provided on the outer wall of the driving punch rod 6 corresponding to the gear groove, and the width of the empty groove 601 is greater than the thickness of the active gear set 5.

[0032] Basic principle: The window breaking method proposed by the present invention is basically similar to the conventional window breaking principle. The driving gear set 5 is rotated to drive the driving punch 6 to move in the direction close to the high-strength spring 4, so that the high-strength spring 4 is compressed to the maximum extent and then directly locks the driving gear set 5, and the sleeve 1 is attached to the car window at one end corresponding to the window breaking punch 7. During the rapid release of the driving punch 6, the window breaking punch 7 quickly impacts the car window under the elastic potential energy of the high-strength spring 4 to achieve the window breaking effect. Figure 3It should be noted that the driving punch rod 6 and the window breaking punch 7 are not directly connected, but maintain a sliding relationship between the two, and a gap of sufficient length is left between the two. The purpose is to ensure that the window breaking punch 7 has enough distance to move in the opposite direction when receiving the reaction force generated by the impact of the car window.

[0033] Embodiment 2: The technical contents in Embodiment 1 are supplemented as follows:

[0034] The following is an explanation of the technology in Example 1:

[0035] S1: First, the driving punch rod 6 is driven to rotate in a directional manner by the pin block 2 to ensure that the gear groove therein is meshed with the active gear set 5, so that the driving punch rod 6 moves in the left direction, and the window breaking punch 7 therein does not move synchronously, and directly locks the active gear set 5. When releasing the driving punch rod 6, there is no need to unlock the active gear set 5, but directly push the pin block 2 to make the empty groove 601 in the gear groove match the active gear set 5, so that there is no meshing relationship between the driving punch rod 6 and the active gear set 5, so that the driving punch rod 6 is quickly released under the elastic potential energy of the high-strength spring 4. It should be noted that when the driving punch rod 6 moves in the right direction, it will not be affected by the active gear set 5, ensuring that the elastic potential energy is released to the maximum extent;

[0036] The first limiting assembly 16 proposed in the present invention is mainly used to maintain the sliding movement and limiting the angle between the driving punch rod 6 and the driving rod 8;

[0037] S2: As shown in S1, when the driving punch 6 moves to the left, the volume of the buffer chamber 1 increases. However, because there is a repulsive force between the pressure punch 12 and the passive punch 13, on the basis of the window breaking punch 7 remaining relatively unchanged, the pressure punch 12 and the passive punch 13 are in a relatively stable state. However, in the process of releasing the driving punch 6, the volume of the buffer chamber 1 shrinks rapidly. In this process, the gas in the buffer chamber 1 is squeezed into the buffer chamber 2, causing the pressure punch 12 to move to the right. However, because the gas in the buffer chamber 1 is compressed, it also causes the window breaking punch 7 to move to the right. It is further explained that: the movement trend of the window breaking punch 7 is higher than the movement trend of the pressure punch 12, thereby forming a passive connection transmission form between the driving punch 6 and the window breaking punch 7;

[0038] S3: It should also be noted that: during the release process of the driving punch 6, the limit pin 11 is first moved upward so that the lower end of the limit pin 11 pushes the driving punch 6, thereby ensuring that the driving punch 6 releases the impact force to the maximum extent. However, when the driving punch 6 moves to a certain distance under the elastic potential energy of the high-strength spring 4, the limit pin 11 is directly inserted into the driving punch 6. The purpose of this is to ensure that the maximum displacement distance of the driving punch 6 is further limited and positioned, so as to avoid further movement of the driving punch 6 when the window-breaking punch 7 moves in the opposite direction, so that the reaction force generated by the car window is reduced by the influence of the high-strength spring 4, thereby maintaining the relevant values ​​during the "recovery" process of the reaction force.

[0039] Embodiment 3: Supplementary explanation of the stress recovery process is provided in combination with Embodiment 1 and Embodiment 2:

[0040] The pressure punch rod 12 is slidably connected in the built-in air cylinder sleeve 9, and a permanent magnet is installed at one end of the pressure punch rod 12 and the passive punch rod 13. The middle position of the driving punch rod 6 corresponding to the window breaking punch 7 and the driving rod 8 is set as a buffer bin 1, and the internal position of the built-in air cylinder sleeve 9 corresponding to one end of the pressure punch rod 12 is set as a buffer bin 2. A vent is set between the buffer bin 1 and the buffer bin 2. A small punch is set at the other end of the passive punch rod 13. The small punch is slidably connected in the window breaking punch 7, and a small punch is opened in the internal position on one side of the window breaking punch 7 corresponding to the small punch. An impact cavity 15 is provided with a plurality of billiard balls 14, the diameter of the billiard balls 14 is equal to the inner diameter of the impact cavity 15, a second limit assembly 17 is provided at the intersection of the driving punch rod 6 and the window breaking punch 7, an auxiliary sleeve 3 is installed on the upper outer wall of the sleeve 1, a limit pin 11 is installed in the auxiliary sleeve 3 for sliding along the vertical direction, the limit pin 11 penetrates downwardly through the outer wall of the sleeve 1, the outer wall position of the driving punch rod 6 corresponding to the empty slot 601 and the outer wall position of the window breaking punch 7, and an auxiliary spring 10 corresponding to the inner wall of the top end of the auxiliary sleeve 3 is installed on the limit pin 11.

[0041] Combined with the relevant contents in Example 2, the following contents are set:

[0042] S4: When the window-breaking punch 7 receives the impact force of the driving punch rod 6 and hits the car window glass, the window-breaking punch 7 directly bears the reaction force and shows a tendency to move to the right. In this process, multiple collisions will first occur between the multiple balls 14 in the impact cavity 15, forming multiple vibration processes, and the passive punch rod 13 will also have a tendency to move to the left. However, the key point is that the entire window-breaking punch 7 moves to the left under the action of the reaction force;

[0043] S5: The technical content in S4 is used for explanation: when the window breaking punch 7 moves to the left direction, the gas in the buffer bin 1 will be further compressed and the gas inside it will be squeezed into the buffer bin 2. However, as shown in the second embodiment, because the overall driving punch 6 is locked by the limit latch 11, the driving punch 6 will not move for the second time, so the gas in the buffer bin 1 is preferentially transferred to the buffer bin 2, causing the compressed punch 12 to move to the right direction due to the change in air pressure, and because a permanent magnet is provided between the compressed punch 12 and the passive punch 13, a repulsive influence relationship is generated, when the compressed punch 1 moves to the right direction, the passive punch 13 will also move to the right direction, so that the small punch at the other end of the passive punch 13 performs a secondary impact on the window breaking punch 7 at the internal position of the window breaking punch 7, and the original power of the secondary impact action is still the high-strength elastic force. The elastic potential energy of the spring 4 is used as the basis, but there is a difference: the power in the secondary impact action is specifically the reaction force generated by the car window on the window breaking punch 7, so that when the small punch quickly hits the window breaking punch 7, the window breaking punch 7 will further hit the car window glass on the original basis, 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 hits the window breaking punch 7, it will also cause the billiard ball 14 to collide multiple times in the impact cavity 15, which can be directly understood as: in the secondary impact process, because the window breaking punch 7 has completed the initial window breaking action, the secondary impact action is mainly to perform a small window breaking by stress recovery, which not only ensures the window breaking effect but also avoids unexpected situations caused by large window breaking force. The stress in the present invention is mainly used to represent the reaction force generated by the car window glass on the window breaking punch 7 in the window breaking action.

[0044] In summary: the compression of the high-strength spring is used as the impact power, and when the driving punch is instantly "released", it drives the window breaking punch to instantly hit the car window glass to achieve the window breaking effect. On this basis, the transmission structure in the process of impact power release is optimized and improved, specifically based on the compressed punch and the passive punch. Its essence is to use the reaction force generated by the car window on the window breaking punch when breaking the window as the power to drive the compressed punch to move axially for the second time, and utilize the magnetic connection relationship between the compressed punch and the passive punch to drive the passive punch to hit the window breaking punch for the second time. In the overall process, the secondary impact process of the window breaking punch is mainly used to optimize and enhance the window breaking, and simultaneously drive the directional movement of the billiard ball in the impact cavity. The key purpose is to "recover" the reaction force generated when breaking the window to enhance the window breaking effect.
