Description

Technical Field

[0001] This utility model relates to the field of window breaker technology, specifically to a multifunctional window breaker. Background Technology

[0002] A window breaker is a tool used to break glass windows or doors. It is usually made of metal or plastic and is commonly used in emergency rescue operations, such as when firefighters need to enter a building or vehicle, or when they need to escape in an emergency. Window breaker is mainly used for emergency rescue of vehicles, most commonly for breaking windows to rescue vehicles that have fallen into water. One type of existing window breaker relies on a compression spring. When compressed to a certain extent, the spring strikes the hammer head, which then hits the glass to break the window. Window breaker also has many additional functions.

[0003] A utility model patent with application number 201920575497.8 discloses a multi-functional flashlight with a window breaker, including a flashlight body and a window breaker assembly. The window breaker assembly includes an inner sleeve, with a first blade holder and a second blade holder on the outer wall of the inner sleeve. A groove is formed between the first and second blade holders, and a cutting blade is provided on the side wall of the first and / or second blade holders. The cutting blade is positioned along the inclined direction of the groove, and the blade head is located within the groove. This utility model has the following advantages and effects: This solution utilizes a new mechanical structure and a concealed cutting blade, which can not only quickly cut seat belts but also prevent accidental injury, thus ensuring high safety; an alarm can be triggered when the horn is turned on; a telescopic and adjustable sleeve is used, which drives the light guide ring through the sliding of the sleeve, thereby adjusting the light distance. When the sleeve extends out of the outer shell, red and blue lights flash alternately, serving as a warning; a sealing plug is provided in the first opening for sealing and waterproofing.

[0004] However, the application only includes the functions of a flashlight, window breaker, and seatbelt cutter. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a window breaker hammer that is simple in structure and simultaneously has the functions of a window breaker, a portable table lamp, a flashlight, a safety belt cutter, a power bank, and an alarm, in order to address the shortcomings of the prior art.

[0006] To achieve the above objectives, the following technical solution is adopted: a multifunctional window breaker hammer, comprising a housing, a window breaking mechanism, a seatbelt cutting mechanism, and a lighting assembly. The window breaking mechanism is extendable and disposed on the top surface of the housing. The seatbelt cutting mechanism and the lighting assembly are respectively disposed on both sides of the housing. The seatbelt cutting mechanism is disposed on one side of the housing and fixedly connected to the housing. A storage cavity is provided on the other side of the housing. The lighting assembly is rotatably stored in the storage cavity. The lighting assembly includes a rotating base. The first end of the rotating base is rotatably disposed on one side of the housing. A lamp holder is rotatably disposed on the second end of the rotating base. A light-transmitting plate is provided on the outer side of the lamp holder. A lamp head is provided on the end of the lamp holder away from the rotating base. A light-transmitting groove is provided on the bottom surface of the housing for the light from the lamp head to pass through when the lamp holder is located in the storage cavity. The rotating base and the lamp holder can rotate toward the top surface of the housing until the light-transmitting plate faces the top surface of the housing.

[0007] Using the above technical solution, the window-breaking structure uses two elastic elements to eject the firing pin, allowing it to extend from the top surface of the housing and achieve the window-breaking effect. Many such window breakers are already available on the market, so further details are omitted. When the lighting component of this application is in its retracted state, its light can shine through from the side and the bottom of the housing. When it shines through from the bottom of the housing (i.e., the light-transmitting groove), it takes the form of a flashlight. Simultaneously, the bottom of the housing can be placed on a table, allowing light to shine through from the side of the product. The connection between the rotating base and the lamp holder, as well as the connection between the rotating base and the housing, can both utilize a combination of lace grooves and arc-shaped protrusions to achieve a certain degree of hovering resistance, enabling it to move freely in any position. Hovering at one angle, flip the rotating base 180° towards the top of the housing (i.e., upwards) so that the rotating base is perpendicular to the top surface of the housing. At this point, one side of the rotating base is also in contact with the inner wall of the storage cavity, thus preventing it from rotating further. Then, fold the lamp base in the same direction, so that the entire window breaker hammer forms a "7" shape, which is similar to the shape of a portable desk lamp. Place the bottom of the housing on a table to use it as a small desk lamp. At the same time, the other side of the housing can also have a seat belt cutting mechanism, i.e., a seat belt cutter. The external shape is similar to the cap clip of a ballpoint pen. The cutter is located between the cap clip and the housing, which can prevent cutting hands and make it easy to cut the seat belt.

[0008] A multifunctional window breaker hammer can be further configured such that the window breaking mechanism includes a striking pin and an abutment cover that extends the striking pin upon impact, the abutment cover being provided with a soft anti-slip pad, and the top surface of the soft anti-slip pad being provided with several anti-slip protrusions.

[0009] The above technical solution involves an opening on the contact cover to allow the striker to extend after contacting the glass. A soft, anti-slip pad causes the contact cover to deform upon contact with the glass, increasing friction. Since window-breaking mechanisms are primarily used for breaking windows at corners, a tilted striker can prevent immediate window breaking, increasing escape time. The anti-slip protrusions prevent the soft anti-slip pad from sliding when in contact with the glass. These protrusions can be irregularly or circumferentially arranged on the soft anti-slip pad; a circumferential arrangement is more aesthetically pleasing. This ensures the striker's head always faces the glass, improving the window-breaking effect. The soft anti-slip pad can be made of adhesive or by embedding a larger protrusion at the bottom into a smaller groove in the contact cover; both methods create a limiting effect.

[0010] A multifunctional window breaker hammer can be further configured such that: a notch is provided on the side of the opening of the storage cavity, and a protrusion is provided on the side of the lamp holder where the light-transmitting lamp plate is located, such that when the lamp holder is located inside the storage cavity, the protrusion is positioned above the notch.

[0011] With the above technical solution, the notch allows fingers to be inserted, thus enabling the lamp holder to be opened more effectively through the protrusion. Without the notch and protrusion, the lamp holder would need to be pried out by fingernails, which could easily damage the side of the lamp holder or cause finger injury.

[0012] A multifunctional window-breaking hammer can be further configured such that: the lamp holder has several heat dissipation grooves on the side facing the storage cavity, and the heat dissipation grooves form a heat dissipation channel with the back of the light-transmitting lamp plate.

[0013] Using the above technical solution, since the light-transmitting light panel will generate a lot of heat after long-term use, it is necessary to set up heat dissipation grooves to form a heat dissipation channel to prevent the circuit board of the light-transmitting light panel from overheating and affecting the lighting life of the light-transmitting light panel, and also to prevent the entire window breaker hammer from overheating and affecting its use.

[0014] A multi-functional window breaker hammer can be further configured such that: the side of the housing where the seat belt cutting mechanism is located is also provided with a power display area, an SOS alarm button, a lighting switch for controlling the lighting components, and a charging / discharging port for charging and discharging.

[0015] Using the above technical solution, the power display area uses four light sources commonly found on power banks to display the power level. Pressing the SOS alarm button will activate the alarm buzzer to serve as a warning. Alternatively, pressing the SOS alarm button can also cause the red and blue lights to flash alternately, similar to the method described in the comparison document. Both solutions can achieve the warning effect. The lighting switch is used to control the on / off state of the lighting or to adjust the brightness by pressing it multiple times. The charging / discharging port uses the most common TYPE-C port, while the discharging port uses a USB port.

[0016] A multi-functional window breaker hammer can be further configured such that: a buzzer connected to an SOS alarm button is provided on one side of the housing opposite to the seat belt cutting mechanism and the lighting assembly, and a waterproof cover is provided above the charging and discharging port.

[0017] Using the above technical solution, the buzzer will not conflict with the function positions of other buttons on this side, and the waterproof cover can effectively prevent water and dust from entering the charging and discharging port. Since window breaker hammers are generally used in vehicles or outdoors, their waterproof and dustproof effects also need to be guaranteed.

[0018] A multifunctional window breaker hammer can be further configured such that: a U-shaped hanging ring groove is provided on the outer ring of the bottom surface of the housing, a hanging ring is rotatably provided in the U-shaped hanging ring groove, and a limiting block is provided on the U-shaped hanging ring groove to abut against the hanging ring when the hanging ring is located in the U-shaped hanging ring groove.

[0019] Using the above technical solution, the hanging ring can be suspended on the keychain, and the hanging ring can also be tilted to allow the base to be placed at different angles. The bottom surface of the shell is generally made of plastic material, which has a certain degree of elasticity. When the hanging ring passes the limit block, it deforms and abuts against each other. The U-shaped hanging ring groove can make the hanging ring more integrated with the bottom surface of the shell when it is stored, thus making it more aesthetically pleasing.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example: Figures 1-7 The multifunctional window breaker hammer shown includes a housing 1, on which a window breaking mechanism 2, a seatbelt cutting mechanism 3, and a lighting component 4 are mounted. The window breaking mechanism 2 is extendable and disposed on the top surface of the housing 1. The seatbelt cutting mechanism 3 and the lighting component 4 are respectively disposed on both sides of the housing 1. Figure 4 , Figure 6 as well as Figure 7As shown, the window breaking mechanism 2 includes a striker 21 and a contact cover 22 that extends the striker 21 after contact with the glass. The contact cover 22 has an opening for the striker 21 to extend after contact with the glass. The contact cover 22 is provided with a soft anti-slip pad 23, and the top surface of the soft anti-slip pad 23 has several anti-slip protrusions 24. The soft anti-slip pad 23 causes the contact cover 22 to deform when it comes into contact with the glass, thereby increasing the friction between the two. At the same time, the anti-slip protrusions 24 are also completely distributed on the top surface of the soft anti-slip pad 23. Since the window breaking mechanism 2 is mainly used for breaking windows at the corners, if the striker 21 is tilted, it will prevent the breaking from happening immediately. The window increases escape time. The anti-slip protrusion 24 prevents the soft anti-slip pad 23 from slipping when it comes into contact with the glass, ensuring that the tip of the striking pin 21 always faces the glass, thus improving the window-breaking effect. The soft anti-slip pad 23 can be made of adhesive or embedded in the smaller groove of the contact cover by a larger protrusion at the bottom. Both methods can create a limiting effect. The window-breaking structure 2 uses two elastic elements to eject the striking pin, allowing it to extend out of the top surface of the housing 1 and achieve the window-breaking effect. The other side of the housing can also have a seat belt cutting mechanism 3, which is a seat belt cutter. The external shape is similar to the cap clip of a ballpoint pen. Located between the cap clip and the housing, it prevents hand cuts and facilitates cutting the seatbelt. The seatbelt cutting mechanism 3 is located on one side of the housing and fixedly connected to the housing 1. The side of the housing 1 where the seatbelt cutting mechanism 3 is located also has a power display area 5, an SOS alarm button 6, a lighting switch 7 for controlling the lighting assembly 4, and a charging / discharging port 8. On one side of the housing 1 opposite to the seatbelt cutting mechanism 3 and the lighting assembly 4, there is a buzzer 9 connected to the SOS alarm button 6. A waterproof cover 81 is provided above the charging / discharging port 8. The other side of the housing 1 has a storage cavity 11. The lighting component 4 is rotatably housed within the storage cavity 11. The lighting component 4 includes a rotating base 41, with its first end rotatably mounted on one side of the housing 1. A lamp holder 42 is rotatably mounted on the second end of the rotating base 41. A light-transmitting lamp plate 43 is provided on the outer side of the lamp holder 42. A lamp head 44 is provided at the end of the lamp holder 42 away from the rotating base 41. The bottom surface of the housing 1 has a light-transmitting groove 45 that allows light from the lamp head 44 to pass through when the lamp holder 42 is located within the storage cavity 11. The side of the lamp holder 42 facing the storage cavity 11 has several heat dissipation grooves 46, which form a heat dissipation channel with the circuit board on the back of the light-transmitting lamp plate 43. Figure 2As shown, when the lighting component 4 of this application is in its retracted state, its light can shine through from the side and the bottom of the housing 1. When it shines through the bottom of the housing 1 (i.e., the light-transmitting groove 45), it takes the form of a flashlight. Simultaneously, the bottom of the housing 1 can be placed on a table, allowing light to shine through from the side of the product. The connection between the rotating base 41 and the lamp holder 42, as well as the connection between the rotating base 41 and the housing 1, can utilize a combination of lace grooves and arc-shaped protrusions to achieve a certain degree of hovering resistance, allowing it to hover at any angle. Figure 4 and Figure 5 As shown, the rotating base 41 is flipped 180° towards the top of the housing 1 (i.e., upwards), making the rotating base 41 perpendicular to the top surface of the housing 1. One side of the rotating base 41 also abuts against the inner wall of the storage cavity 11, thus preventing further rotation. Then, the lamp holder 42 is also folded in this direction, so that the entire window breaker hammer forms a "7" shape, similar to the shape of a portable desk lamp. The bottom of the housing 1 can be placed on a table to be used as a small desk lamp. The side of the opening of the storage cavity 11 has a notch 12. The side of the lamp holder 42 with the light-transmitting lamp plate 43 has a protrusion 421. When the lamp holder 42 is in the storage cavity 11, the protrusion 421 is above the notch 12. The rotating base 41 and the lamp holder 42 can rotate towards the top surface of the housing 1 until the light-transmitting lamp plate 43 faces the top surface of the housing 1. Figure 3 As shown, the outer ring of the bottom surface of the housing 1 is provided with a U-shaped hanging ring groove 13, and a hanging ring 14 is rotatably provided in the U-shaped hanging ring groove 13. A limiting block 15 is provided on the U-shaped hanging ring groove 13 to abut against the hanging ring 14 when the hanging ring 14 is located in the U-shaped hanging ring groove 13.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
