[0002] The vehicle-mounted number plate is usually placed on the vehicle instrument desk or the rear windshield, clearly showing the contact phone number of the vehicle owner, so that others can quickly contact the vehicle owner. In order to meet the needs of the vehicle owner, some vehicle-mounted number plates integrate the window breaking function, and the window breaking function on the vehicle-mounted number plate is used to break the window in an emergency.

[0003] In the related art, the vehicle-mounted number plate integrating the window breaking function has obvious limitations. This type of number plate usually adopts the working principle of a traditional safety hammer, that is, a metal structure with a hammer head is arranged at one end of the number plate, and the number plate needs to be held and hit the vehicle window glass with force during use.

[0071] The vehicle-mounted window breaking device of the utility model embodiment is described in detail below with reference to the drawings.

[0072] Referring to Figures 1 to 5 As shown in the drawings, according to the vehicle-mounted window breaking device provided by the utility model embodiment, it comprises a shell 10, a column shell 20 and a window breaker 30.

[0073] Specifically, the housing 10 is provided with a display window H101. Exemplarily, the housing 10 is in a hollow columnar structure, and the display window H101 is in a rectangular shape, which has an area size capable of completely displaying a telephone number.

[0074] The columnar shell 20 is sleeved in the housing 10 and rotates around its axis between a display position and a hidden position. The columnar shell 20 is generally in a cylindrical shape, and its outer diameter is slightly smaller than the radial dimension of the inner cavity of the housing 10, so that the columnar shell 20 can freely rotate around its axis in the housing 10.

[0075] The outer surface of the columnar shell 20 is provided with a number area. Preferably, the number area can be written or replaced with digits to combine different telephone numbers. When the columnar shell 20 is in the display position, the number area is exposed in the display window H101, and when the columnar shell 20 is in the hidden position, the number area is misaligned with the display window H101 to hide the number area. That is, when the columnar shell 20 is in the display position, the number area is opposite to the display window H101, so that the telephone number on the number area is displayed through the display window H101. When the columnar shell 20 is rotated to the hidden position, the number area is misaligned with the display window H101, so that the telephone number is hidden, effectively protecting the privacy of the vehicle owner.

[0076] The window breaker 30 is mounted at one end of the columnar shell 20, and the window breaker 30 comprises an abutting head 301, a striker 302, a first elastic member 304, and a locking member 303. The abutting head 301 is slidably arranged at one end of the columnar shell 20 and at least partially protrudes from one end of the columnar shell 20. That is, the abutting head 301 is arranged at the end of the columnar shell 20 and can slide along the axis of the columnar shell 20. When the abutting head 301 abuts against the glass window with force, the reaction force of the glass window can make the abutting head 301 slide into the columnar shell 20 along the axis of the columnar shell 20. Exemplarily, the protruding part of the abutting head 301 is in a circular truncated cone shape, which is convenient for abutting against the glass. The inside of the abutting head 301 is hollow, which is convenient for the striker 302 to pass through.

[0077] The striker 302 is slidably arranged in the columnar shell 20 along the axis of the columnar shell 20, and the first elastic member 304 is arranged in the columnar shell 20 and provides an axial elastic force to the striker 302. Preferably, the first elastic member 304 is a compression spring, one end of which abuts against a structure inside the columnar shell 20, and the other end abuts against the striker 302 or the locking member 303. In the initial state, the first elastic member 304 is in a compressed state and stores elastic potential energy. The striker 302 is made of metal and has high structural strength. One end of the striker 302 is formed in a tapered shape, which is more conducive to breaking the glass.

[0078] The locking piece 303 is arranged on the striker 302 and is locked with the abutting head 301. The locking piece 303 can be fixed relative to the striker 302, and the striker 302 and the locking piece 303 can move synchronously in the axial direction. When the abutting head 301 is subjected to the reaction force of the glass window and slides into the column shell 20, the locking between the locking piece 303 and the abutting head 301 is released, and the striker 302 is ejected from the abutting head 301 under the axial elastic force to break the glass window.

[0079] The vehicle-mounted window breaking device provided in the embodiment of the present application realizes the dual functions of number display and safe window breaking, adopts the rotating mode of the column shell 20 to control the display and hiding of the number, protects the privacy of the vehicle owner, and facilitates the quick display of the contact mode when needed. In the window breaking function, the mechanical principle of spring energy storage and striker 302 release is adopted. When the abutting head 301 contacts the glass and slides inwards under the force, the locking piece 303 is automatically triggered to release, the striker 302 stored with energy is ejected at high speed under the axial elastic force, an instantaneous high-speed impact force is generated, and the effect of quick and labor-saving window breaking is achieved. This design not only improves the window breaking efficiency and reduces the use difficulty, but also helps the user to complete the window breaking and escape in the shortest time in an emergency, greatly improving the ease of use and reliability of the window breaking function.

[0080] Exemplarily, the column shell 20 includes two half shells 201, and the two half shells 201 are combined to form the column shell 20, facilitating the processing and assembly between the components. The two half shells 201 can be fixed by buckling, screw locking or the like.

[0081] Referring to FIGS. 1 to 5, Figure 2 Figure 4 and Figure 5 In some embodiments of the present application, the locking piece 303 includes a center part 3031 and an elastic part 3032, and the center part 3031 is fixed on the striker 302. It can be understood that the center part 3031 can be made of the same material as the striker 302 and formed as an integral structure. Alternatively, the center part 3031 can be made of a different material from the striker 302 and fixed by a fixing structure, for example, the locking piece 303 is made of a plastic material with a certain elasticity, and the center part 3031 is fixed on the striker 302 by an injection molding process. Preferably, the center part 3031 is in a columnar shape and is coaxially fixed on the striker 302.

[0082] The elastic part 3032 is arranged on the center part 3031 and elastically abuts against the abutting head 301 under the axial elastic force. Preferably, the elastic part 3032 is formed as an integral structure with the center part 3031, the elastic part 3032 abuts against the abutting head 301 in the axial direction, the striker 302 is locked and fixed in the column shell 20, and at this time, the first elastic member 304 is in a compressed state to store elastic potential energy.​

[0083] The inner wall of the column shell 20 is provided with a touch pressure part 2013, which can be a protruding part protruding inward from the inner wall of the column shell 20. The elastic part 3032 has a pressure receiving slope for bearing the extrusion pressure of the touch pressure part 2013 during unlocking. The abutting head 301 is provided with a cavity adjacent to one end of the locking piece 303, which serves as a clearance space, so that after the locking piece 303 is unlocked, the locking piece 303 can enter the clearance space with the striker 302, preventing interference from hindering the ejection movement of the striker 302. The abutting head 301 is provided with a needle hole communicating with the cavity at the end away from the locking piece 303, which is used for the ejection of the striker 302.

[0084] When the abutting head 301 slides inward under the reaction force of the glass window, the abutting head 301 pushes the touch pressure part 2013 of the elastic part 3032 close to the touch pressure part 2013, which acts on the pressure receiving slope, forcing the elastic part 3032 to deform radially inward and release the abutment with the abutting head 301, and reversely move under the axial elastic force to enter the cavity, and the striker 302 is ejected from the needle hole.

[0085] During use, when the user abuts the abutting head 301 against the car window glass and applies pressure, the abutting head 301 slides inward under the reaction force of the glass window. At this time, the abutting head 301 drives the locking piece 303 to move in the direction of the touch pressure part 2013. As the pressure receiving slope of the elastic part 3032 gradually contacts and abuts against the touch pressure part 2013, the touch pressure part 2013 applies radial pressure to the pressure receiving slope. Under the pressure, the elastic part 3032 is forced to deform inward and gradually release the abutment with the abutting head 301.

[0086] When the elastic part 3032 completely releases the abutment with the abutting head 301, the striker 302 moves rapidly in the direction of the end of the abutting head 301 together with the locking piece 303 under the axial elastic force of the first elastic member 304. At this time, the elastic part 3032 enters the cavity, and the front end of the striker 302 is ejected from the needle hole in the abutting head 301 at high speed, using the instantaneous impact force to break the car window glass.

[0087] The present embodiment realizes automatic unlocking in use through the cooperation of the elastic part 3032 and the touch pressure part 2013. When the abutting head 301 is forced, the elastic part 3032 automatically contracts under the action of the touch pressure part 2013, without the need for additional unlocking operation, so that the entire window breaking process is rapid and smooth. At the same time, through the cavity and the needle hole provided on the abutting head 301, the reliable movement and accurate guidance of the striker 302 are ensured, and the success rate of window breaking is improved. This design not only simplifies the operation steps and improves the use convenience, but also significantly improves the window breaking efficiency and reliability.

[0088] Referring to Figure 4 As shown in the utility model one embodiment, locking piece 303 further includes sliding part 3033, the sliding part 3033 is located on the center part 3031 and projects to the outside along the radial direction, the cylindrical shell 20 is equipped with the limiting slot H201 that is slidably matched with the sliding part 3033, the limiting slot H201 extends along the axial direction of the cylindrical shell 20, to limit the distance of the axial movement of the striker 302.

[0089] Sliding part 3033 can be manufactured with center part 3031 using an integral molding process, forming an overall structure. Sliding part 3033 can be a bump or boss structure, extending outward from the outer surface of the center part 3031. Limiting slot H201 is used to accommodate and guide the movement of sliding part 3033. The length of the limiting slot H201 is determined according to the required movement distance of the striker 302, by limiting the movement stroke of the sliding part 3033, thereby limiting the distance of the axial movement of the striker 302.

[0090] When the striker 302 moves axially under the action of the first elastic member 304, the sliding part 3033 slides synchronously in the limiting slot H201. Since the limiting slot H201 has a fixed length, when the sliding part 3033 moves to the end of the limiting slot H201, the striker 302 will be prevented from continuing to move. This design can effectively prevent the striker 302 from moving too much and avoid the striker 302 from completely disengaging from the cylindrical shell 20. At the same time, through the cooperation of the sliding part 3033 and the limiting slot H201, the movement of the striker 302 can also be guided, ensuring that the striker 302 moves along the predetermined axial path and improving the stability of the movement of the striker 302.

[0091] This embodiment realizes precise control and reliable guidance of the movement distance of the striker 302 by providing the sliding part 3033 on the locking piece 303 and the corresponding limiting slot H201 on the cylindrical shell 20. This design not only prevents the striker 302 from disengaging from the device body, ensuring safety in use, but also improves the stability and accuracy of the movement of the striker 302, further enhancing the reliability of the breaking window function.

[0092] Referring to Figure 2 , Figure 4 and Figure 5 As shown in the utility model one embodiment, the elastic part 3032 is formed as a sheet body, which is arranged upwardly inclined from the direction away from the abutting head 301 to the direction close to the abutting head 301 in the axial direction of the striker 302.

[0093] The elastic sheet can be made of a plastic material with elasticity, and the inclination angle of the elastic sheet is preferably 15° to 45°. Such an inclination arrangement makes the elastic sheet more easily deformed when subjected to radial pressure, which is conducive to realizing reliable unlocking.

[0094] During use, when the abutting head 301 is forced to slide inward, the elastic sheet is deformed inward under the extrusion of the contact pressure portion 2013. Since the elastic sheet is arranged obliquely, under the radial pressure of the contact pressure portion 2013, the elastic sheet will be smoothly elastically deformed until it is completely separated from the abutment of the abutting head 301. Such a gradual unlocking process ensures the reliability and safety of unlocking.

[0095] Preferably, the elastic portion 3032 is two, and the two elastic portions 3032 are symmetrically arranged in the radial direction of the central portion 3031. The two elastic portions 3032 are arranged at an interval of 180° along the circumferential direction of the central portion 3031, forming a symmetrical structure. Such a symmetrical arrangement makes the force more uniform during locking and unlocking, thereby ensuring that the movement of the striker 302 is more stable and reliable. At the same time, the abutment between the two symmetrically arranged elastic portions 3032 and the abutting head 301 is more stable, enhancing the reliability of locking.

[0096] Referring to Figure 2 and Figure 4 In an embodiment of the present application, the window breaker 30 further comprises a second elastic member 305, which is arranged between the locking member 303 and the abutting head 301, and the elastic coefficient of the second elastic member 305 is smaller than that of the first elastic member 304. The second elastic member 305 can also be a compression spring, one end of which abuts against the central portion 3031, and the other end abuts against the end of the abutting head 301 away from the locking member 303.

[0097] When the abutting head 301 is subjected to the reaction force of the glass window, the abutting head 301 slides into the cylindrical shell 20. Before the locking member 303 is unlocked, since the abutting head 301 pushes the striker 302 and the locking member 303 to move synchronously, the second elastic member 305 remains in the initial state. When the elastic portion 3032 comes into contact with the contact pressure portion 2013, the elastic portion 3032 is gradually deformed under the action of the contact pressure portion 2013 until the locking is completely released. At this time, the axial elastic force of the first elastic member 304 forces the striker 302 and the locking member 303 to move rapidly in the direction, the locking member 303 enters the cavity of the abutting head 301, and the striker 302 pops out of the needle hole of the abutting head 301. In this process, since the striker 302 and the locking member 303 move relative to the abutting head 301, the second elastic member 305 is compressed.

[0098] In the embodiment, the second elastic member 305 is arranged on the abutting head 301 and the locking member 303, and the elastic coefficient of the second elastic member 305 is smaller than that of the first elastic member 304. In this way, on the one hand, the second elastic member 305 can always provide a pre-tightening force for the abutting head 301 to keep the abutting head 301 in the state of extending from one end of the column shell 20, thereby ensuring the reliability in use; on the other hand, the smaller elastic coefficient of the second elastic member 305 can not affect the ejection of the striker 302 by the first elastic member 304.

[0099] It can be understood that, in actual application, the second elastic member 305 can provide a pre-tightening force for the abutting head 301 to extend, and the elastic coefficient of the second elastic member 305 is smaller, while the first elastic member 304 needs to provide an axial elastic force for driving the striker 302 to eject, so the elastic coefficient of the first elastic member 304 can be relatively larger, and the impact force of the striker 302 after ejection can only be ensured to be able to break the glass.
