Description

Technical Field

[0001] This application relates to the field of automotive testing technology, and in particular to automotive testing window breakers. Background Technology

[0002] FMVSS226 is a motor vehicle occupant ejection safety standard developed by the National Highway Traffic Safety Administration (NHTSA) in the United States. It mainly assesses the occupant ejection performance during side impacts and rollover collisions. The core test requirements include testing the impact resistance of the side windows corresponding to the first three rows of seats and some side windows in the cargo box area. During the test, a specific impact device must be used to conduct impact tests on different points around the window glass. In some test scenarios, the window glass is also required to undergo pre-fracture treatment to simulate the condition of premature glass breakage in a real collision.

[0003] Currently, in the FMVSS226 test, the window breaking operation for side windows includes pre-breakage and the precise window breaking required for the test. Existing operations mostly use general-purpose window breaker hammers, impact drills, or manual impact tools. During the test, operators need to hold general-purpose tools at close range to break the side window of the test vehicle. The operator's force control is unstable, which can easily cause the tool to slip during the window breaking process, further increasing the safety risk. When operators use general-purpose tools, the operation efficiency is low and the consistency is poor. General-purpose tools lack positioning and guiding structures, and each window breaking operation requires the use of auxiliary tools such as tape measures and marking lines to locate the impact point, which is cumbersome and time-consuming. At the same time, the operating force and angle of different operators are different, resulting in inconsistent results from multiple window breaking operations, which cannot meet the consistency requirements of repeated tests in the FMVSS 226 test. Summary of the Invention

[0004] To address or partially address the problems existing in related technologies, this application provides an automotive test window breaker that can improve the operational efficiency of users when using the automotive test window breaker.

[0005] This application provides a test window breaker for automobiles, comprising a main body, a drive mechanism, and an impact mechanism. The main body has a receiving cavity. The drive mechanism includes an elastic element, a locking element, and a control element. The elastic element is located in the receiving cavity, one end of which is connected to the main body. The locking element is also connected to the main body. The control element is exposed outside the main body and connected to the locking element. The control element is used to control the locking element to compress or release the elastic element. The impact mechanism includes an impact head and a connecting rod. One end of the connecting rod is located inside the receiving cavity and connected to the other end of the elastic element. The end of the connecting rod away from the elastic element is located outside the main body and connected to the impact head. The impact head is used to shatter the glass.

[0006] Furthermore, the locking member is rotatably connected to the main body, and the control member is rotatably connected to the main body. The control member abuts against the locking member, and the control member pushes the locking member to rotate so that the locking member enters or exits the extension path of the elastic member.

[0007] Furthermore, the automotive test window breaker also includes an adsorption mechanism, which includes an extension tube and an adsorption head. The extension tube is connected to the main body and is sleeved outside the connecting rod. The adsorption head is connected to the end of the extension tube away from the main body, and the adsorption head is used to adsorb the car window.

[0008] Furthermore, the adsorption head is annular and surrounds the impact head.

[0009] Furthermore, the main body includes a housing, a movable seat, and an adjusting member. The housing forms the receiving cavity, the movable seat is located in the receiving cavity, one end of the elastic member is connected to the movable seat, and the adjusting member is connected to the movable seat. The adjusting member is used to drive the movable seat to move toward the connecting rod.

[0010] Furthermore, the adjusting member is rotatably connected to the housing, the adjusting member is threadedly connected to the movable seat, the main body also includes an anti-rotation shaft, the anti-rotation shaft is located in the receiving cavity, the length direction of the anti-rotation shaft is the same as the length direction of the connecting rod, and the movable seat is slidably connected to the anti-rotation shaft.

[0011] Furthermore, the anti-rotation shaft passes through the movable seat, and the surface of the anti-rotation shaft is provided with a lubricating layer.

[0012] Furthermore, the automotive test window breaker also includes a pressure sensor located in the receiving cavity and connected to the movable seat, the pressure sensor being used to detect the pressure of the movable seat.

[0013] Furthermore, the diameter of the end of the impact head furthest from the connecting rod is 4-6 mm.

[0014] Furthermore, the automotive test window breaker also includes a limiting member located in the receiving cavity, the limiting member being radially positioned on the connecting rod and abutting against the connecting rod.

[0015] The technical solution provided in this application may include the following beneficial results: This application compresses the elastic element through the locking element. When the impact head needs to break the glass, the elastic element can be released through the locking element, so that the elastic element generates elastic force on the connecting rod and drives the impact head to break the glass. The overall structure of the automotive test window breaker is simple and compact, highly reliable, easy to maintain and low in cost; it is convenient for single-person handheld operation. A single person can complete the entire process of positioning, force adjustment, angle adjustment, window breaking and disassembly with one hand, without the need for multiple people to cooperate, which greatly improves the operating efficiency, reduces the labor cost of testing, and is suitable for single-person operation scenarios.

[0024] In related technologies, window breaking operations for side windows include pre-breaking and precise window breaking required for testing. Existing operations often employ general-purpose window breaker hammers, impact drills, or manual impact tools. During testing, operators must hold these general-purpose tools at close range to break the side window of the test vehicle, resulting in inconsistent force control and low efficiency and inconsistency when using general-purpose tools. To address these issues, this application provides an automotive testing window breaker that improves the user's operational efficiency.

[0025] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0026] See Figure 1 and Figure 2The automotive test window breaker includes a main body 1, a drive mechanism 2, and an impact mechanism 3. The main body 1 has a receiving cavity. The drive mechanism 2 includes an elastic element 21, a locking element 22, and a control element 23. One end of the elastic element 21 is connected to the main body 1, and the other end is connected to the impact mechanism 3. The locking element 22 is connected to the main body 1. The locking element 22 can press against one end of the elastic element 21, thus compressing the elastic element 21; the locking element 22 can also release the elastic element 21, causing the elastic element 21 to exert a spring force on the impact mechanism 3.

[0027] See Figure 1 and Figure 2 The control element 23 is partially located inside the main body 1, and partially exposed outside the main body 1. The control element 23 is connected to both the locking element 22 and the main body 1, and is used to control the locking element 22 to compress or release the elastic element 21. The impact mechanism 3 includes an impact head 31 and a connecting rod 32. One end of the connecting rod 32 is located inside the receiving cavity and is connected to the elastic element 21. The end of the connecting rod 32 away from the elastic element 21 is located outside the main body 1, and is connected to the impact head 31, which is used to shatter the glass. When the user presses the control element 23, the control element 23 controls the locking element 22 to release the elastic element 21. The elastic element 21 extends and generates a spring force on the connecting rod 32. Under the action of the spring force, the connecting rod 32 drives the impact head 31 to move away from the main body 1, allowing the impact head 31 to collide with the glass at high speed and shatter it. The elastic element 21 is located in the receiving cavity. The elastic element 21 is a spring. The elastic element 21 is made of high-strength alloy spring with stable elastic coefficient and high fatigue strength. It can withstand multiple reciprocating impacts without elastic decay, ensuring the stability and force consistency of the automotive test window breaker in long-term use.

[0028] This application uses a locking element 22 to compress an elastic element 21. When the impact head 31 needs to break the glass, the locking element 22 can release the elastic element 21, causing the elastic element 21 to generate a spring force on the connecting rod 32 and drive the impact head 31 to break the glass. The overall structure of the automotive test window breaker is simple and compact, highly reliable, easy to maintain and low in cost. It is easy for a single person to operate by hand. A single person can complete the entire process of positioning, force adjustment, angle adjustment, window breaking and disassembly with one hand, without the need for multiple people to cooperate, which greatly improves the efficiency of operation, reduces the labor cost of testing, and is suitable for single-person operation scenarios.

[0029] See Figure 1-3The locking element 22 is rotatably connected to the main body 1, and the control element 23 is also rotatably connected to the main body 1. The control element 23 abuts against the locking element 22 and can rotate relative to the main body 1, thereby pushing the locking element 22 to rotate. By pushing the locking element 22 to rotate, the control element 23 causes the locking element 22 to engage or disengage from the telescopic path of the elastic element 21. When the car window breaker is not in use, the elastic element 21 is in a compressed state, and the locking element 22 engages with the telescopic path of the elastic element 21, with the locking element 22 abutting against one end of the elastic element 21. When the user presses the control element 23, the control element 23 rotates relative to the main body 1, and simultaneously pushes the locking element 22 to rotate. The locking element 22 disengages from the telescopic path of the elastic element 21 and releases the elastic element 21. The elastic element 21 generates a spring force on the connecting rod 32, and the impact head 31 can shatter the glass. The control component 23 is provided with a stop part 231, which abuts against the main body 1. The direction of the pressure exerted by the stop part 231 on the main body 1 is opposite to the direction of the user pressing the control component 23. The stop part 231 can prevent the elastic element 21 from pushing open the locking element 22, ensuring that the elastic element 21 is always in a compressed state when the car test window breaker is not in use.

[0030] See Figure 1-3 The automotive window breaker also includes an adsorption mechanism 4, which comprises an extension tube 41 and an adsorption head 42. The extension tube 41 is connected to the main body 1 and is sleeved around the connecting rod 32, which can slide relative to the extension tube 41. The adsorption head 42 is connected to the end of the extension tube 41 furthest from the main body 1 and is used to adsorb the window. When a user needs to break the window, the adsorption head 42 can be adsorbed onto the window to locate the position where the impact head 31 needs to break the glass, ensuring that the impact head 31 can accurately break the window. In some embodiments, the adsorption head 42 can be a suction cup, which can be adsorbed onto the glass by negative pressure.

[0031] See Figure 1 and Figure 2 The suction head 42 is annular and surrounds the impact head 31. When the impact head 31 breaks the glass, the suction head 42 prevents glass shards from flying towards the user, thus protecting the user's safety. The suction head 42 and the impact head 31 are coaxially aligned, ensuring accurate positioning of the impact point. The automotive window breaker requires no additional auxiliary operation, significantly improving the efficiency of single-person operation.

[0032] See Figure 1-3The main body 1 includes a housing 11, a movable seat 12, and an adjusting member 13. A receiving cavity is formed within the housing 11, and the movable seat 12 is located within the receiving cavity. The movable seat 12 can move along the length of the connecting rod 32. One end of the elastic element 21 is connected to the movable seat 12, and the adjusting member 13 is connected to the movable seat 12, driving the movable seat 12 to move towards the connecting rod 32. When the elastic element 21 is in a compressed state, the user can rotate the adjusting member 13, which controls the movement of the movable seat 12 along the length of the connecting rod 32, thereby adjusting the compression of the elastic element 21. This allows for precise control of the impact force of the impact head 31, stably controlling the impact force within the range of 150N±25N, with a force accuracy within ±10N. This precisely matches the force requirements of the glass contact point and the direction perpendicular to the window tangent in the FMVSS 226 test. The compression of the elastic element 21 can be flexibly adjusted to switch the force according to the test scenario, offering wide compatibility, strong practicality, adaptability to diverse test needs, strong operational consistency, and suitability for multiple repeated tests.

[0033] See Figure 1-3 The adjusting member 13 is rotatably connected to the housing 11. Part of the adjusting member 13 is located inside the main body 1, and part is located outside the main body 1. The adjusting member 13 is annular, and its inner surface has an internal thread. The outer surface of the movable seat 12 has an external thread. The adjusting member 13 is threadedly connected to the movable seat 12 through the engagement of the internal and external threads. The main body 1 also includes an anti-rotation shaft 14, located in the receiving cavity. The length direction of the anti-rotation shaft 14 is the same as the length direction of the connecting rod 32. The movable seat 12 is slidably connected to the anti-rotation shaft 14, which prevents the movable seat 12 from rotating relative to the main body 1. When the user moves the adjusting member 13, the adjusting member 13 rotates and drives the movable seat 12 to move along the length direction of the connecting rod 32, thereby adjusting the compression of the elastic member 21.

[0034] See Figure 2 and Figure 3 The anti-rotation shaft 14 passes through the movable seat 12. Specifically, the movable seat 12 has a through hole through which the anti-rotation shaft 14 passes. The surface of the anti-rotation shaft 14 is provided with a lubricating layer. The lubricating layer can make the movable seat 12 slide more smoothly relative to the anti-rotation shaft 14, making it easier for the user to adjust the compression of the elastic element 21.

[0035] See Figure 2 and Figure 3 The automotive test window breaker also includes a pressure sensor 5, which is located in the receiving cavity and connected to the movable seat 12. The pressure sensor 5 is used to detect the pressure on the movable seat 12. In some embodiments, the pressure sensor 5 abuts against the elastic member 21. The pressure sensor 5 can detect the magnitude of the elastic force applied by the elastic member 21 to the movable seat 12, thereby understanding the magnitude of the impact force generated by the impact head 31 after the locking member 22 releases the elastic member 21.

[0036] See Figure 1-3 The diameter of the end of the impact head 31 furthest from the connecting rod 32 is 4-6 mm. In some embodiments, the diameter of the end of the impact head 31 furthest from the connecting rod 32 is 5 mm. The impact head 31 is made of hard alloy material and has a cylindrical needle-like structure. The end of the impact head 31 furthest from the connecting rod 32 is rounded with a radius of 0.5 mm. This ensures that the force generated when the impact head 31 breaks the glass is concentrated at the glass contact point for precise window breaking, while also preventing the impact head 31 from being too sharp and causing excessive glass fragments to fly, thus reducing damage to the window frame.

[0037] See Figure 1-3 The automotive test window breaker also includes a limiting member 6, which is located in the receiving cavity and is radially positioned on the connecting rod 32, abutting against the connecting rod 32. The limiting member 6 can limit the connecting rod 32, ensuring that after the locking member 22 releases the elastic member 21, the connecting rod 32 can move in a straight line, ensuring that the impact head 31 can accurately shatter the glass.
