Abstract
Description
Technical Field
[0001] This application relates to the field of safety protection accessories technology, and in particular to a window breaker. Background Technology
[0002] In the event of a vehicle accident, breaking a window is an important self-rescue method for passengers. A safety hammer is typically used as an emergency escape tool. When breaking a window, it is necessary to accurately strike the weakest point of the window to shatter the glass.
[0003] However, after an accident, the occupants of the vehicle are often in a weak and panicked state. In this state, striking the window may result in inaccurate positioning or insufficient force, leading to failure to break the window and rendering the safety hammer ineffective. Utility Model Content
[0004] To address the aforementioned technical problems, this application provides a window breaker that uses an electrically controlled drill bit to provide stronger window-breaking force, thereby reducing the requirements for the window-breaking location and force and improving the effectiveness of the window breaker.
[0005] This application provides a window breaker, comprising: a housing having a receiving space, the housing including first housing walls facing each other and a pressing part, the first housing wall having a through hole, the pressing part being movable toward or away from the first housing wall; a drill assembly including a drill bit extending from the through hole and a motor capable of driving the drill bit to rotate; a power supply assembly housed in the receiving space and electrically connected to the drill assembly, including a contact switch for switching the circuit of the power supply assembly and the motor; the pressing part is configured to push the drill bit out of the through hole under the drive of an external force and trigger the contact switch to turn on the circuit of the power supply assembly and the motor.
[0006] In the technical solution of this application embodiment, since an electrically controlled drill bit is provided, the rotation of the drill bit can provide a strong window-breaking force, reducing the requirements for the user and helping to improve the success rate of window breaking. Because the pressing part is configured to push the drill bit out of the through hole and trigger the contact switch under external force, the user only needs to press the pressing part to simultaneously connect the power and extend the drill bit, simplifying the usage steps, making it convenient and quick to use, and helping to improve the effectiveness of the window breaker.
[0007] In some embodiments, the power supply assembly further includes a battery, and the contact switch includes a conductive trigger, a first conductive element, and a second conductive element. The first conductive element is electrically connected to a first electrode of the battery and the drill bit assembly, respectively. The second conductive element is electrically connected to the drill bit assembly and the trigger. The trigger is located on the pressing part, and the second electrode of the battery is located on the moving path of the trigger. During the movement of the trigger, it contacts the second electrode of the battery to make the circuit of the battery and the motor conductive.
[0008] Therefore, simply moving the pressing part can simultaneously turn on the power and extend the drill bit. The rotation of the drill bit can provide strong window-breaking force. It is easy to use, has a good window-breaking effect, helps to shorten the time required for users to break windows, and improves the effectiveness of the window breaker.
[0009] In some embodiments, the window breaker further includes a first elastic element disposed between the first housing wall and the drill assembly, for moving the drill away from the through hole and receiving it in the receiving space.
[0010] Because the first elastic element is provided in the first housing wall and the drill bit assembly, the drill bit is housed in the receiving space when there is no external force, which helps to reduce the size of the window breaker, making it easier to carry, and the drill bit can be protected by the housing. In addition, the first elastic element also acts as a shock absorber during use.
[0011] In some embodiments, the window breaker further includes a second elastic element disposed between the pressing portion and the battery.
[0012] Therefore, when there is no external pressure, the second elastic element can keep the trigger and the battery at a certain distance, reducing the probability of accidental contact and conduction between the trigger and the battery.
[0013] In some embodiments, along the moving direction of the pressing portion, the first elastic member, the drill bit assembly, the battery, and the second elastic member are arranged sequentially in the receiving space, and the trigger member protrudes from the surface of the pressing portion toward the battery. When the pressing portion presses the second elastic member, the trigger member contacts the battery.
[0014] Since the first elastic element, drill bit assembly, battery, and second elastic element are arranged sequentially in the receiving space, the components are arranged more compactly, which helps to reduce the space occupied by the window breaker. Pressing the pressing part can simultaneously compress the first and second elastic elements, causing the drill bit to extend out of the receiving space and the trigger to contact the battery, simplifying the usage steps and helping to shorten the time required to break the window.
[0015] In some embodiments, the elastic modulus of the first elastic element is less than that of the second elastic element.
[0016] Therefore, under the same external force, the deformation of the first elastic element is greater than that of the second elastic element, which allows the drill bit to extend first and then open, helping to prevent the drill bit from spinning idly in the receiving space. Moreover, the pressure required to open the drill bit is greater, which helps to reduce the risk of accidental collisions squeezing the drill bit to open.
[0017] In some embodiments, the window breaker further includes a slider housed within the housing space, the housing further includes a peripheral sidewall located between the first housing wall and the pressing portion, the peripheral sidewall is provided with a first groove, the slider is mounted in the first groove and is capable of sliding along the first groove, and the drill assembly and the power supply assembly are disposed on the slider.
[0018] Since both the drill bit assembly and the power supply assembly are located on the sliding member, their relative positions are fixed, preventing collisions or relative rotation and improving reliability. Because the sliding member is mounted on a first groove on the peripheral wall, it only moves along that groove, further preventing rotation or wobbling of the drill bit assembly and power supply assembly within the receiving space.
[0019] In some embodiments, the peripheral sidewall is further provided with a second sliding groove, the pressing part is configured with a sliding protrusion that is slidably connected to the second sliding groove, and a limiting protrusion is configured at the end of the second sliding groove away from the first housing wall.
[0020] Therefore, after the pressing part moves a certain distance away from the first housing wall, the sliding protrusion contacts the limiting protrusion and is blocked by the limiting protrusion, so that the pressing part will not detach from the peripheral side wall.
[0021] In some embodiments, the pressing portion includes a cover and a sliding seat having the sliding protrusion. The cover is disposed on the side of the sliding seat away from the first housing wall. On the same projection plane perpendicular to the moving direction of the pressing portion, the projection of the peripheral sidewall is located within the projection of the cover.
[0022] Therefore, after the pressing part moves a certain distance toward the first housing wall, the cover contacts the peripheral side wall and is blocked by the peripheral side wall, thereby limiting the movement range of the pressing part.
[0023] In some embodiments, two spaced-apart limiting protrusions are constructed within the second groove, and the sliding protrusions are slidable between the two limiting protrusions.
[0024] Therefore, the sliding protrusion can only slide within the second groove between the limiting protrusions, thus restricting the range of movement of the pressing part.
[0025] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0043] The following is a detailed description of this application.
[0044] In the event of a vehicle accident, breaking a window is an important self-rescue method for passengers. A safety hammer is typically used as an emergency escape tool. When breaking a window, it is necessary to accurately strike the weakest point of the window to shatter the glass.
[0045] However, after an accident, the occupants of the vehicle are often in a weak and panicked state. In this state, striking the window may result in inaccurate positioning or insufficient force, leading to failure to break the window and rendering the safety hammer ineffective.
[0046] This application provides a window breaker, comprising: a housing having a receiving space, the housing including a first housing wall and a pressing part facing each other, the first housing wall having a through hole, and the pressing part being movable toward or away from the first housing wall; a drill assembly including a drill bit extending from the through hole and a motor capable of driving the drill bit to rotate; a power supply assembly housed in the receiving space and electrically connected to the drill assembly, including a contact switch for switching the circuit of the power supply assembly and the motor; the pressing part being configured to push the drill bit out of the through hole under the drive of an external force and trigger the contact switch to turn on the circuit of the power supply assembly and the motor.
[0047] Because it features an electrically controlled drill bit, its rotation provides strong force for breaking windows, reducing the demands on the user and increasing the success rate. The pressing mechanism is designed to push the drill bit out of the through-hole and trigger a contact switch under external force. Therefore, users only need to press the pressing mechanism to simultaneously connect the power and extend the drill bit, simplifying the process and making it convenient and quick to use, thus improving the effectiveness of the window breaker.
[0048] The following explanation is based on the accompanying drawings.
[0049] Figure 1 A perspective view of a window breaker provided in one embodiment of this application; Figure 2 A perspective view of a window breaker concealing the peripheral sidewalls, provided as an embodiment of this application; Figure 3 A perspective view of a window breaker concealed behind the peripheral sidewalls, provided as an embodiment of this application; Figure 4 A perspective view of a window breaker with a slider provided in one embodiment of this application; Figure 5 A perspective view of a window breaker with a sliding element provided in another embodiment of this application; Figure 6 This is a perspective view of the peripheral sidewall provided for an embodiment of this application.
[0050] This application provides a window breaker, such as Figures 1 to 3 As shown, the window breaker includes: a housing 10 having a receiving space, the housing 10 including a first housing wall 11 facing each other and a pressing part 12, the first housing wall 11 having a through hole 111, and the pressing part 12 being movable toward or away from the first housing wall 11; a drill assembly 20 including a drill bit 21 extending from the through hole 111 and a motor 22 capable of driving the drill bit 21 to rotate; a power supply assembly 40, housed in the receiving space and electrically connected to the motor 22, including a contact switch for switching the circuit of the power supply assembly 40 and the motor 22; the pressing part 12 is configured to push the drill bit 21 out of the through hole 111 under the drive of an external force and trigger the contact switch to turn on the circuit of the power supply assembly 40 and the motor 22.
[0051] The window breaker includes a housing 10, a drill assembly 20, and a power supply assembly 40. The housing 10 has a receiving space in which the drill assembly 20 is at least partially received, and the power supply assembly 40 is also received. When the window breaker is not in use, the entire drill assembly 20 is received within the receiving space.
[0052] The outer casing 10 includes at least a first casing wall 11 and a pressing part 12. The first casing wall 11 and the pressing part 12 are directly opposite each other. A through hole 111 is provided on the first casing wall 11, through which the receiving space communicates with the outside. The pressing part 12 is movable toward or away from the first casing wall 11.
[0053] Furthermore, the outer casing 10 also includes a peripheral sidewall 13. The extending direction of the peripheral sidewall 13 is perpendicular to the extending direction of the first casing wall 11. The first casing wall 11 and the peripheral sidewall together form a box with an opening on one side, and the pressing part 12 seals the opening of the box. The peripheral sidewall 13 may be arranged around the pressing part 12, or the pressing part 12 may be arranged around the peripheral sidewall 13. The pressing part 12 and the peripheral sidewall 13 are in close contact with each other, so that a certain frictional force is maintained between them, thereby fixing the position of the pressing part 12 relative to the first casing wall 11. Under the action of external force, the pressing part 12 can be pushed to move closer to the first casing wall 11.
[0054] The drill assembly 20 includes a drill bit 21 and a motor 22. The motor 22 is electrically connected to the power supply assembly 40. The drill bit 21 is positioned facing the first housing wall 11 and directly opposite the through hole 111. The drill bit 21 can rotate under the drive of the motor 22, providing strong window-breaking force. When an external force pushes the pressing part 12 towards the first housing wall 11, the pressing part 12 pushes the drill assembly 20, causing the drill bit 21 to extend out of the through hole 111 on the first housing wall 11. The power supply assembly 40 includes a contact switch for controlling the on / off state of the circuit between the power supply assembly 40 and the motor 22. The contact switch can be located on the movement path of the pressing part 12.
[0055] The pressing part 12 is configured to push the drill bit 21 out of the through hole 111 under the drive of an external force and trigger a contact switch. Optionally, the drill bit assembly 20 is connected to or abuts against the pressing part 12, so that the drill bit assembly 20 moves together with the pressing part 12. The contact switch may be provided on the movement path of the drill bit assembly 20 or the pressing part 12.
[0056] Alternatively, a power supply component 40 may be provided between the pressing part 12 and the drill bit assembly 20. The power supply component 40 is connected to or abuts against the pressing part 12, so that the drill bit assembly 20 and the power supply component 40 move together with the pressing part 12. A contact switch may be provided on the movement path of the drill bit assembly 20 or the pressing part 12.
[0057] Alternatively, a slider 60 may be connected to or abut against the pressing part 12, and a drill bit assembly 20 may be mounted on the slider 60, so that the slider 60 and the drill bit assembly 20 move together with the pressing part 12. A contact switch may be located on the movement path of any of the drill bit assembly 20, the pressing part 12, and the slider 60.
[0058] In the technical solution of this application embodiment, since an electrically controlled drill bit 21 is provided, the rotation of the drill bit 21 can provide a strong window-breaking force, reducing the requirements on the user and helping to improve the success rate of window breaking. Since the pressing part 12 is configured to push the drill bit 21 out of the through hole 111 and trigger the contact switch under the drive of external force, the user only needs to press the pressing part 12 to simultaneously realize the power supply and the extension of the drill bit 21, simplifying the use steps, making it convenient and quick to use, and helping to improve the effectiveness of the window breaker.
[0059] In some embodiments, such as Figures 2 to 4 As shown, the power supply component 40 also includes a battery 41. The contact switch includes a conductive trigger 42, a first conductive element 43, and a second conductive element 44. The first conductive element 43 is electrically connected to the first electrode of the battery 41 and the drill bit assembly 20, respectively. The second conductive element 44 is electrically connected to the drill bit assembly 20 and the trigger 42, respectively. The trigger 42 is located on the pressing part 12. The second electrode of the battery 41 is located on the moving path of the trigger 42. During the movement of the trigger 42, it contacts the second electrode of the battery 41 to make the circuit between the battery 41 and the motor 22 conduct.
[0060] The power supply assembly 40 also includes a battery 41. The battery 41 can be a cylindrical battery, a prismatic battery, or a pouch battery, or it can be a lithium-ion battery, a sodium-ion battery, or a sodium-lithium-ion battery, etc. This application does not impose any special limitations on the shape and type of the battery 41. The battery 41 has a first electrode and a second electrode. Exemplarily, the first electrode is the positive electrode, and the second electrode is the negative electrode.
[0061] The contact switch includes a trigger element 42, a first conductive element 43, and a second conductive element 44. All three elements—trigger element 42, first conductive element 43, and second conductive element 44—are made of a conductive material. The first conductive element 43 is electrically connected to the first electrode of the battery 41 and the motor 22, respectively, and the second conductive element 44 is electrically connected to the motor 22 and the trigger element 42, respectively. Exemplarily, both the first conductive element 43 and the second conductive element 44 are wires.
[0062] A trigger 42 is disposed on the pressing part 12, allowing the trigger 42 to move with the pressing part 12. The second electrode of the battery 41 is located on the moving path of the trigger 42. In the absence of external force, the trigger 42 is separated from the second electrode, thus disconnecting the circuit between the battery 41 and the motor 22.
[0063] The battery 41 and drill bit assembly 20 can be arranged sequentially along the moving direction of the pressing part 12, with the second electrode of the battery 41 facing the pressing part 12. A trigger 42 is provided on the side of the pressing part 12 facing the second electrode. When the pressing part 12 moves toward the first housing wall 11, the trigger 42 contacts the second electrode, connecting the circuit and pushing the battery 41 and drill bit assembly 20 toward the first housing wall 11.
[0064] In an optional embodiment, the contact switch further includes a conductive piece. A peripheral sidewall 13 surrounds the pressing portion 12, and a trigger element 42 connected to the pressing portion 12 is disposed between the pressing portion 12 and the peripheral sidewall 13. The conductive piece is electrically connected to a second electrode and is disposed on the inner wall surface of the peripheral sidewall 13, located on the moving path of the trigger element 42. When the pressing portion 12 moves the trigger element 42 to the conductive piece, the trigger element 42 contacts the conductive piece, thus connecting the circuit. Furthermore, the conductive piece disposed on the peripheral sidewall 13 extends along the moving direction of the pressing portion 12, allowing the trigger element 42 to continuously contact the conductive piece within a certain range.
[0065] Therefore, simply moving the pressing part 12 can simultaneously turn on the power and extend the drill bit 21. The rotation of the drill bit 21 can provide strong window-breaking force. The method of use is simple, the window-breaking effect is good, and it helps to shorten the time required for users to break windows and improve the effectiveness of the window breaker.
[0066] In some embodiments, the window breaker further includes a first elastic element 30 disposed between the first housing wall 11 and the drill assembly 20, for moving the drill 21 away from the through hole 111 and receiving it in the receiving space.
[0067] Because the first elastic element 30 is provided on the first housing wall 11 and the drill assembly 20, the drill bit 21 is housed in the receiving space when there is no external force, which helps to reduce the size of the window breaker, making it easy to carry, and the drill bit 21 can be protected by the housing 10. In addition, the first elastic element 30 can also play a role in shock absorption during use.
[0068] In some embodiments, see continue to see Figures 2 to 4 The window breaker also includes a second elastic element 50, which is disposed between the pressing part 12 and the battery 41.
[0069] The window breaker also includes a second elastic element 50. The second elastic element 50 is disposed between the pressing part 12 and the battery 41. Specifically, a trigger 42 protruding from the surface of the pressing part 12 is provided on the side of the pressing part 12 facing the battery 41, and the second elastic element 50 is sleeved around the periphery of the trigger 42. In the absence of external force, there is a gap between the trigger 42 and the battery 41. When an external force pushes the pressing part 12 to compress the second elastic element 50, the gap between the trigger 42 and the battery 41 decreases until it contacts the battery 41.
[0070] The second elastic element 50 and the first elastic element 30 may use the same elastic structure or elastic material. For example, the first elastic element 30 may include a spring, and the second elastic element 50 may also include a spring. Alternatively, the second elastic element 50 and the first elastic element 30 may use different elastic structures or elastic materials. For example, the first elastic element 30 may include a spring, and the second elastic element 50 may include a rubber component. This application does not impose any special limitations on the specific structure and material of the first elastic element 30 and the second elastic element 50.
[0071] Therefore, when there is no external pressure, the second elastic element 50 can keep the trigger 42 and the battery 41 at a certain distance, reducing the probability of the trigger 42 and the battery 41 accidentally making contact and conducting.
[0072] In some embodiments, such as Figures 2 to 4 As shown, along the moving direction of the pressing part 12, the first elastic member 30, the drill bit assembly 20, the battery 41 and the second elastic member 50 are arranged in sequence in the receiving space. The trigger member 42 protrudes from the surface of the pressing part 12 toward the battery 41. When the pressing part 12 presses the second elastic member 50, the trigger member 42 contacts the battery 41.
[0073] From the first housing wall 11 to the pressing part 12, a first elastic element 30, a drill bit assembly 20, a battery 41, and a second elastic element 50 are arranged sequentially. The first electrode of the battery 41 faces the drill bit assembly 20 and is electrically connected to the drill bit assembly 20 through a first conductive element 43. The second electrode of the battery 41 faces the pressing part 12 and is electrically connected to the trigger element 42 through a second conductive element 44.
[0074] In use, press the pressing part 12 towards the first housing wall 11 to compress the first elastic member 30 and the second elastic member 50. The trigger member 42 contacts the second electrode of the battery 41, connecting the battery 41 to the circuit of the drill assembly 20, and the drill bit 21 rotates. The drill bit 21 then protrudes from the through hole 111, enabling it to break windows.
[0075] Since the first elastic element 30, the drill bit assembly 20, the battery 41 and the second elastic element 50 are arranged sequentially in the receiving space, the arrangement of each component is relatively compact, which helps to reduce the space occupied by the window breaker. Furthermore, pressing the pressing part 12 can simultaneously compress the first elastic element 30 and the second elastic element 50, causing the drill bit 21 to extend out of the receiving space and the trigger 42 to contact the battery 41, simplifying the usage steps and helping to shorten the time required to break the window.
[0076] In some embodiments, the elastic modulus of the first elastic element 30 is less than the elastic modulus of the second elastic element 50.
[0077] The elastic modulus of the first elastic element 30 is less than that of the second elastic element 50. Under the same external force, the compression of the first elastic element 30 is greater than that of the second elastic element 50. That is, the moving distance of the drill bit 21 relative to the first housing wall 11 is greater than the moving distance of the trigger 42 relative to the battery 41.
[0078] When in use, press the pressing part 12 to make the drill bit 21 extend out of the through hole 111 first. During the process of the drill bit 21 extending out of the through hole 111 or after the drill bit 21 extends out, the trigger 42 contacts the battery 41 to connect the circuit.
[0079] Therefore, under the same external force, the deformation of the first elastic element 30 is greater than that of the second elastic element 50, which allows the drill bit 21 to extend first and then open, which helps to prevent the drill bit 21 from spinning idly in the receiving space. Moreover, the pressure required to open the drill bit 21 is greater, which helps to reduce the risk of accidental collisions squeezing the drill bit 21 to open.
[0080] In some embodiments, such as Figures 4 to 6 As shown, the window breaker also includes a sliding member 60 housed in the housing space, and the outer casing 10 also includes a peripheral sidewall 13 located between the first housing wall 11 and the pressing part 12. The peripheral sidewall 13 is provided with a first sliding groove 131. The sliding member 60 is installed in the first sliding groove 131 and can slide along the first sliding groove 131. The drill assembly 20 and the power supply assembly 40 are provided on the sliding member 60.
[0081] The outer casing 10 also includes a peripheral sidewall 13. The peripheral sidewall 13 is located between the first casing wall 11 and the pressing part 12, and the extending direction of the peripheral sidewall 13 is perpendicular to the extending direction of the first casing wall 11. The pressing part 12 can move closer to or further away from the first casing wall 11 relative to the peripheral sidewall 13. The peripheral sidewall 13, the first casing wall 11, and the pressing part 12 together form an accommodating space.
[0082] The window breaker also includes a slider 60. The slider 60 is housed in a receiving space and is movable relative to the first housing wall 11. The drill assembly 20 and the power supply assembly 40 may be disposed on the slider 60.
[0083] Specifically, the slider 60 has two cavities arranged along the moving direction of the pressing part 12, and a partition is provided between the two cavities to separate them. A drill assembly 20 is disposed in the first cavity near the first housing wall 11, and a power supply assembly 40 is disposed in the second cavity near the pressing part 12. A first conductive member 43 penetrates the partition and is electrically connected to both the power supply assembly 40 and the drill assembly 20. A second conductive member 44 penetrates the wall of the first cavity and is electrically connected to both the drill assembly 20 and the trigger member 42.
[0084] The surface of the peripheral sidewall 13 facing the receiving space is provided with a first groove 131, and the extending direction of the first groove 131 is parallel to the moving direction of the pressing part 12. The slider 60 has a movable protrusion 61 that can be inserted into and engaged with the first groove 131. The slider 60 is mounted on the first groove 131 through the movable protrusion 61 and can move along the first groove 131.
[0085] Furthermore, two mutually spaced limiting protrusions can be constructed within the first slide groove 131, allowing the slider 60 to slide on the first slide groove 131 between the two limiting protrusions, thereby limiting the range of movement of the slider 60.
[0086] Since both the drill bit assembly 20 and the power supply assembly 40 are located on the slider 60, their relative positions are fixed, preventing collisions or relative rotation and improving reliability. Because the slider 60 is mounted on the first groove 131 on the peripheral wall 13, it will only move along the first groove 131, helping to prevent the drill bit assembly 20 and the power supply assembly 40 from rotating or wobbling within the receiving space.
[0087] In some embodiments, such as Figure 6 As shown, the peripheral sidewall 13 is also provided with a second sliding groove 132, and the pressing part 12 is constructed with a sliding protrusion 121 that is slidably connected to the second sliding groove 132. A limiting protrusion is constructed at the end of the second sliding groove 132 away from the first housing wall 11.
[0088] A second sliding groove 132 is provided on the peripheral sidewall 13 near the pressing part 12, and the extension direction of the second sliding groove 132 is parallel to the moving direction of the pressing part 12. A sliding protrusion 121 is constructed on the surface of the pressing part 12 facing the peripheral sidewall 13. The sliding protrusion 121 engages within the second sliding groove 132 and can slide along the second sliding groove 132. A limiting protrusion is constructed within the second sliding groove 132, and the limiting protrusion is disposed away from the first housing wall 11.
[0089] The first slide groove 131 and the second slide groove 132 can be constructed as an integral structure, that is, the first slide groove 131 and the second slide groove 132 are parallel and connected. Alternatively, the first slide groove 131 and the second slide groove 132 can be constructed as separate structures.
[0090] Therefore, after the pressing part 12 moves a certain distance away from the first housing wall 11, the sliding protrusion 121 contacts the limiting protrusion and is blocked by the limiting protrusion, so that the pressing part 12 will not detach from the peripheral side wall 13.
[0091] In some embodiments, such as Figure 4As shown, the pressing part 12 includes a cover 122 and a sliding seat 123 with a sliding protrusion 121. The cover 122 is located on the side of the sliding seat 123 away from the first housing wall 11. On the same projection plane perpendicular to the moving direction of the pressing part 12, the projection of the peripheral side wall 13 is located within the projection of the cover 122.
[0092] The pressing part 12 includes a cover 122 and a sliding seat 123. The cover 122 and the sliding seat 123 are connected to each other. The periphery of the sliding seat 123 is surrounded and fitted by a peripheral sidewall 13. A sliding protrusion 121 is formed on the surface of the sliding seat 123 facing the peripheral sidewall 13. The sliding seat 123 is mounted on the second slide groove 132 through the sliding protrusion 121 and can slide along the second slide groove 132. A trigger member 42 is provided on one side of the sliding seat 123, and this side abuts against or connects to the second elastic member 50. The other side of the sliding seat 123 is connected to the cover 122.
[0093] On the same projection plane perpendicular to the moving direction of the pressing part 12, the projection of the outer shell 10 lies within the projection of the cover 122. In other words, the radial dimension of the outer shell 10 is smaller than the radial dimension of the cover 122.
[0094] Therefore, after the pressing part 12 moves a certain distance toward the first housing wall 11, the cover 122 contacts the peripheral side wall 13 and is blocked by the peripheral side wall 13, thereby limiting the movement range of the pressing part 12.
[0095] In some embodiments, two spaced-apart limiting protrusions are constructed within the second groove 132, and the sliding protrusion 121 is capable of sliding between the two limiting protrusions.
[0096] Two mutually spaced limiting protrusions are constructed in the second slide groove 132, and the sliding protrusion 121 is located between the two limiting protrusions, so that the sliding protrusion 121 slides in the second slide groove 132 between the two limiting protrusions.
[0097] Therefore, the sliding protrusion 121 can only slide within the second groove 132 between the limiting protrusions, thus limiting the range of movement of the pressing part 12.
[0098] In some embodiments, a first elastic element 30, a drill bit 21, a motor 22, a battery 41, and a second elastic element 50 are arranged sequentially from the first housing wall 11 to the pressing part 12. The motor 22 is connected to the drill bit 21 and can drive the drill bit 21 to rotate. The motor 22 is electrically connected to the battery 41 through a first conductive element 43.
[0099] The following describes a specific embodiment of this application.
[0100] The window breaker includes a housing 10, a drill assembly 20, a pressing part 12, and two springs.
[0101] The outer casing 10 includes a peripheral sidewall 13 and an end cap (first casing wall 11). The peripheral sidewall 13 and the end cap (first casing wall 11) are connected. A through hole 111 is provided on the end cap (first casing wall 11).
[0102] The drill assembly 20 includes an electric motor (motor 22). The electric motor (motor 22) drives the drill bit 21 to rotate. When the pressing part 12 is pressed, it pushes the drill assembly 20 forward, pushing the drill bit 21 out of the through hole 111. The power supply circuit of the electric motor (motor 22) is turned on, driving the drill bit 21 to rotate. Local stress is applied to the vehicle glass, completing the window breaking.
[0103] An electric motor (motor 22) is mounted on the drill bit 21 bracket (slider 60). A first groove 131 and a second groove 132 are arranged in the peripheral side wall 13. The first groove 131 cooperates with the rib (moving protrusion 61) on the drill bit 21 bracket (slider 60), and the second groove 132 cooperates with the rib (sliding protrusion 121) on the pressing part 12, so that the corresponding parts can realize translational movement.
[0104] The drill bit 21 bracket (slider 60) has two cavities inside for mounting the electric motor (motor 22) and the battery 41. The positive terminal of the battery 41 is connected to the electric motor (motor 22) via the first conductive member 43. A hole is formed in the cavity of the drill bit 21 bracket (slider 60) for mounting the electric motor (motor 22), and a second conductive member 44 extends from this hole, runs along the extension direction of the drill bit 21 bracket (slider 60), and connects to the negative terminal pin (trigger member 42) of the pressing part 12.
[0105] Two springs are respectively installed at both ends of the drill bit 21 bracket (slider 60). The spring located between the end cap (first housing wall 11) and the drill bit 21 bracket (slider 60) is used to reset the drill bit 21 bracket (slider 60) and to absorb shock during use. The spring located between the pressing part 12 and the drill bit 21 bracket (slider 60) is used to pop open the negative terminal and disconnect the power supply to the electric motor (motor 22).
[0106] The pressing part 12 includes a tail button (cover 122) and a negative electrode bracket (slider 123). The tail button (cover 122) and the negative electrode bracket (slider 123) are fixed together as a whole. They slide synchronously within the peripheral sidewall 13 via a rib (sliding protrusion 121).
[0107] In the standby state, the spring between the end cap (first housing wall 11) and the drill bit 21 bracket (slider 60) opens, pushing the drill bit 21 bracket (slider 60) back into the receiving space; the spring between the pressing part 12 and the drill bit 21 bracket (slider 60) opens, pushing the negative terminal pin (trigger 42) away from the battery 41, disconnecting the circuit. In the working state, the force applied to the button compresses the two springs, connecting the electric motor (motor 22) circuit, driving the drill bit 21 to rotate. At the same time, driven by the pressing pressure, the drill bit 21 bracket (slider 60) pushes the drill bit 21 out of the through hole 111, allowing the drill bit 21 to rotate and break the window.
