[0031] With the increase in the number of cars, traffic accidents are also increasing. In accidents, seat belt failures, door and window failures become fatal dangers for drivers and passengers. Therefore, safety hammers and window breakers came into being, but traditional safety hammers are heavy and bulky, not easy to carry. Installing them on the car affects the appearance of the vehicle and occupies a large area, especially not suitable for small cars; then the emergence of portable window breakers solved the troubles of many car drivers. It is small in size and easy to carry. It can generally be hung on the keychain, but most people are reluctant to carry extra objects when traveling. Because portable window breakers are rarely used, they are often forgotten at home, thus failing to achieve the effect of emergency response in sudden emergencies. The related technology configures a window-breaking hammer in a car charger with a window-breaking function so that it can be used as a window breaker in an emergency, but when using it, the user still needs to apply a large force to achieve the window-breaking effect, which reduces the convenience of using the car charger with a window-breaking function when breaking the window.

[0032] The utility model provides a vehicle charger with a window breaking function, aiming to solve the technical problem of how to improve the use convenience of the vehicle charger with the window breaking function when the window is broken.

[0033] In the embodiment of the present utility model, Figures 1 to 3 As shown, Figure 1 This is a structural schematic diagram of an embodiment of a vehicle charger with a window breaking function of the utility model; Figure 2 It is a cross-sectional schematic diagram of an embodiment of a vehicle charger with a window breaking function of the utility model; Figure 3 It is a structural schematic diagram of an embodiment of a window breaking assembly in the utility model.

[0034] The vehicle charger with window breaking function comprises: a housing 10, wherein one end of the housing 10 in the length direction is provided with a telescopic hole; a charging assembly 20, wherein the charging assembly 20 is installed in the housing 10; a window breaking assembly, wherein the window breaking assembly is installed in the housing 10, wherein the window breaking assembly comprises a positive telescopic member 31, an impact member 32, a limit transmission member 33 and a driving member 34; wherein the positive telescopic member 31 is slidably installed in the housing 10, wherein the positive telescopic member 31 comprises a positive contact head 311, wherein the positive contact head 311 extends out of the telescopic hole, and wherein the positive contact head 311 is provided with an impact channel 313; The limiting transmission member 33 is opposite to the impact channel 313 and can be detached from the abutment with the positive telescopic member 31. One end of the impact member 32 is connected to the limiting transmission member 33, and the other end is telescopically matched with the impact channel 313. The driving member 34 is arranged on the side of the limiting transmission member 33 away from the impact member 32, so as to apply an impact driving force to the limiting transmission member 33. The limiting transmission member 33 is used to detach from the positive telescopic member 31 when the positive contact head 311 is forced to retract into the telescopic hole, so as to push the impact member 32 out of the impact channel 313 under the action of the driving member 34.

[0035] In this embodiment, the housing 10 is provided with a first cavity and a second cavity arranged along the length direction, the charging assembly 20 is installed in the first cavity, the window breaking assembly is installed in the second cavity, and the telescopic hole is connected to the second cavity. The charging assembly 20 includes a circuit board and a charging cable, and the charging cable is electrically connected to the circuit board and passes through the housing 10 for plugging and charging of electronic devices. The shell wall of the housing 10 is provided with a negative spring, and the negative spring and the positive contact head 311 are both electrically connected to the circuit board. When it is necessary to use a car charger with a window breaking function, one end of the car charger with a window breaking function provided with a positive contact head 311 can be plugged into the cigarette lighter in the car, so that the cigarette lighter forms a discharge circuit with the circuit board through the positive contact head 311 and the negative spring.

[0036] The positive contact head 311 extends out of the telescopic hole under normal conditions, and can be retracted into the telescopic hole when pushed, while driving the positive telescopic member 31 to slide as a whole. The limit transmission member 33 is in limited contact with the positive telescopic member 31 under normal conditions, so that the positive telescopic member 31 can limit the movement of the limit transmission member 33 toward the telescopic hole. When the positive telescopic member 31 moves toward the inside of the telescopic hole, the limit transmission member 33 and the positive telescopic member 31 are released from the limited abutment state, that is, the movement path of the limit transmission member 33 toward the telescopic hole is no longer hindered by the positive telescopic member 31. At this time, the driving member 34 applies an impact driving force to the limit transmission member 33, pushing the limit transmission member 33 and the impact member 32 toward the telescopic hole together, and finally quickly pushing the impact member 32 out of the impact channel 313.

[0037] When the on-board charger with window-breaking function needs to be used to break a window, the positive contact head 311 can be pressed against the window glass and pressure can be applied to the on-board charger with window-breaking function. The positive contact head 311 will shrink into the telescopic hole under the pressure and drive the positive telescopic member 31 to move. The movement of the positive telescopic member 31 will cause the limit transmission member 33 to be separated from the positive telescopic member 31, so that the limit transmission member 33 can move toward the telescopic hole. Under the impact driving force of the driving member 34, the limit transmission member 33 can quickly push the impact member 32 out of the impact channel 313, so that sufficient impact force can be applied to the window glass abutted by the positive contact head 311, so that the window glass is broken. Since the impact member 32 hits the window glass under the action of the driving member 34, there is no need for the user to apply impact force. Therefore, in an emergency, the user can break the window more promptly and conveniently, thereby improving the convenience of using the on-board charger with window-breaking function when breaking a window.

[0038] Specifically, Figure 2 and Figure 3As shown, the limiting transmission member 33 includes a transmission part 331 and a limiting spring piece 332, the transmission part 331 is located between the impact member 32 and the driving member 34, and the impact member 32 is connected to the transmission part 331; one end of the limiting spring piece 332 is connected to one end of the transmission part 331 close to the driving member 34, and the other end is limitedly abutted against the positive telescopic member 31; the window breaking assembly also includes an extrusion member 35, the extrusion member 35 is arranged on a side of the positive telescopic member 31 away from the telescopic hole, and the extrusion member 35 abuts against a side of the limiting spring piece 332 away from the transmission part 331; when the positive telescopic member 31 approaches the extrusion member 35, the extrusion member 35 slides and abuts against the limiting spring piece 332 and squeezes the limiting spring piece 332 to separate from the positive telescopic member 31.

[0039] The transmission part 331 is used to transmit the impact driving force of the driving member 34 to the impact member 32, and the limiting spring piece 332 is used to limit the position of the positive telescopic member 31 to limit the movement of the transmission part 331. The limiting spring piece 332 has a fixed end and a free end, the fixed end is connected to the transmission part 331, and the free end is abutted against the positive telescopic member 31. The distance between the limiting spring piece 332 and the transmission part 331 gradually increases from the fixed end to the free end, and the free end of the limiting spring piece 332 can be elastically deformed in the direction of approaching or moving away from the transmission part 331. When the positive contact head 311 is pushed into the telescopic hole, the positive telescopic member 31 moves toward the extrusion member 35 and pushes the limiting transmission member 33 to move in the direction away from the telescopic hole. When the limiting spring piece 332 moves, it will slide and abut against the extrusion piece 35, and the distance between the extrusion piece 35 and the transmission part 331 is fixed. Therefore, when the free end of the limiting spring piece 332 passes through the extrusion piece 35, it will be deformed in the direction close to the transmission part 331 under the action of the extrusion piece 35. The deformed limiting spring piece 332 is separated from the abutment with the positive telescopic piece 31. At this time, the limiting transmission part 33 as a whole is not restricted by the positive telescopic piece 31, so that the transmission part 331 can move close to the telescopic hole under the action of the driving member 34 to push the impact member 32 to extend out of the impact channel 313.

[0040] In practical applications, a tip may be provided at one end of the impact member 32 located in the impact channel 313 to increase the pressure generated when impacting the vehicle window glass, thereby breaking the vehicle window glass more effectively.

[0041] The extrusion member 35 may be protruded from the inner wall surface of the housing 10 , or may be protruded from other structures, which is not limited here.

[0042] For example, Figure 2 and Figure 3As shown, the window breaking assembly also includes a mounting tube 36, the limiting transmission member 33 and the driving member 34 are both installed in the mounting tube 36, and the extrusion member 35 is protruded from the inner wall surface of the mounting tube 36; the positive telescopic member 31 also includes a matching tube 312, and the matching tube 312 is connected to one end of the positive contact head 311 in the shell 10, and the matching tube 312 and the mounting tube 36 can be slidably matched, and the limiting spring piece 332 abuts against the end of the matching tube 312 away from the positive contact head 311.

[0043] The installation cylinder 36 can protect the limited transmission member 33, the driving member 34, the impact member 32, etc. installed therein. When the on-board charger with the window-breaking function is subjected to external force due to falling or other situations, the force will not be directly transmitted to the limited transmission member 33, the driving member 34, the impact member 32, etc. in the installation cylinder 36, thereby preventing the various components of the window-breaking assembly from being misplaced, so as to improve the structural stability of the window-breaking assembly. Furthermore, the installation cylinder 36 can also realize the pre-assembly of the window-breaking assembly outside the housing 10. When assembling the on-board charger with the window-breaking function, the limited transmission member 33, the driving member 34, the impact member 32, etc. can be assembled into the installation cylinder 36 first, and then the main structure of the assembled window-breaking assembly can be installed into the housing 10, thereby simplifying the assembly process of the on-board charger with the window-breaking function and improving the assembly efficiency. In addition, the installation cylinder 36 can also increase the matching area with the positive telescopic member 31 to prevent the positive telescopic member 31 from moving unsmoothly, so as to improve the activity stability of the positive telescopic member 31.

[0044] The number of the limiting spring pieces 332 may be one, or two or more, which is not limited here.

[0045] Specifically, Figure 2 and Figure 3 As shown, the number of the limiting spring pieces 332 is at least two, and at least two of the limiting spring pieces 332 are arranged at intervals along the circumference of the transmission part 331, and the free ends of at least two of the limiting spring pieces 332 are both in contact with the matching cylinder 312; the number and position of the extrusion member 35 correspond to the limiting spring pieces 332. In this way, the limiting contact position between the limiting transmission member 33 and the matching cylinder 312 can be increased to improve the limiting effect of the limiting transmission member 33, and prevent the limiting transmission member 33 from easily misunderstanding to release the restriction and accidentally push out the impact member 32.

[0046] For example, Figure 3 and Figure 4As shown, the peripheral wall of the transmission part 331 is provided with a guide protrusion 333, and the cylinder wall of the installation cylinder 36 is provided with a guide groove 361, and the guide groove 361 extends along the movement direction of the transmission part 331, and the guide protrusion 333 and the guide groove 361 can be slidably matched. The guide protrusion 333 is arranged to avoid the position-limiting spring sheet 332 to prevent the guide protrusion 333 from affecting the deformation process of the position-limiting spring sheet 332. The number of the guide protrusions 333 can be set to two and respectively arranged on the opposite sides of the transmission part 331, and the number and position of the guide grooves 361 correspond to the guide protrusions 333. When the transmission part 331 is pushed, the guide protrusion 333 can slide along the guide groove 361, thereby preventing the transmission part 331 from deviating on the movement track, so as to improve the stability of the movement process of the position-limiting transmission member 33.

[0047] The impact driving force generated by the driving member 34 is an instantaneous explosive force. The driving member 34 can be a pneumatic impactor or a hydraulic impactor, and there is no limitation here. It only needs to be able to generate an instantaneous impact force.

[0048] In practical applications, such as Figure 2 and Figure 3 As shown, the driving member 34 is configured as an elastic member, for example, a compression spring or a gun-type spring. One end of the driving member 34 abuts against the limiting telescopic member, and the other end abuts against the inner wall structure of the housing 10. When the positive telescopic member 31 pushes the limiting transmission member 33 to move in a direction away from the telescopic hole, the limiting transmission member 33 will further compress the driving member 34. When the positive telescopic member 31 removes the restriction on the limiting transmission member 33, the driving member 34 releases kinetic energy and applies an impact driving force to the limiting transmission member 33. Applying the impact driving force through the elastic member can not only meet the instantaneous burst demand of the impact driving force, but also simplify the structure of the driving member 34.

[0049] For example, Figure 2 and Figure 3 As shown, the window breaking assembly further includes a guide column 37, which is connected to the side of the transmission part 331 away from the impact member 32, and the driving member 34 is a spring and is sleeved on the guide column 37. The guide column 37 can ensure that the driving member 34 can be effectively compressed when pressure is applied, and can release the impact driving force in a preset direction when the pressure is removed, thereby improving the working stability of the driving member 34.

[0050] The positive electrode contact head 311 can be directly electrically connected to the charging assembly 20 through a wire, or can be electrically connected to the charging assembly 20 through an intermediate conductive structure, which is not limited here.

[0051] Specifically, the impact member 32, the transmission part 331 and the guide post 37 are all made of conductive materials, the charging assembly 20 is located on the side of the window-breaking assembly away from the positive contact head 311, and the guide post 37 is electrically connected to the charging assembly 20 through a wire. The positive contact head 311 and the charging assembly 20 can transmit current through the impact member 32, the transmission part 331 and the guide post 37, so that the wire does not need to pass through the window-breaking assembly to be directly connected to the positive contact head 311, so as to avoid the wire being torn off when the window-breaking assembly takes effect, thereby improving the conductive stability of the charging assembly 20.

[0052] In practical applications, such as Figure 2 and Figure 3 As shown, the window breaking assembly also includes a reset member 38 sleeved on the impact member 32, one end of the reset member 38 abuts against the positive telescopic member 31, and the other end abuts against the limit transmission member 33, and the reset member 38 is used to reset the limit transmission member 33 and the impact member 32 in a direction away from the telescopic hole, and reset the positive contact head 311 in a direction extending out of the telescopic hole. The reset member 38 can be an elastic reset member 38, for example, it can be a spring. After the limit transmission member 33 pushes the impact member 32 to break the window under the action of the driving member 34, the reset member 38 releases kinetic energy to push the limit transmission member 33 and the positive telescopic member 31 back to their original positions, respectively, for next use. In this way, the on-board charger with a window breaking function can be restored to its original state after the window is broken, rather than being used once, thereby avoiding waste of the on-board charger with a window breaking function.

[0053] For example, Figure 1 and Figure 2 As shown, the on-board charger with window-breaking function further includes a cutting knife 40, and the cutting knife 40 is installed on the outer wall surface of the housing 10. The cutting knife 40 can be used for the user to pick up the on-board charger with window-breaking function to cut the seat belt in an emergency escape situation, thereby increasing the emergency safety function of the on-board charger with window-breaking function.

[0054] Specifically, Figure 1 and Figure 2As shown, the outer wall of the housing 10 is provided with a boss 11, and the boss 11 is provided with a cutting groove 12, the notch of the cutting groove 12 is consistent with the direction of the telescopic hole, and the cutting knife 40 is installed in the cutting groove 12, and the blade of the cutting knife 40 faces the notch of the cutting groove 12. The cutting knife 40 is arranged in the cutting groove 12 to prevent the cutting knife 40 from being exposed when not in use, so as to avoid the user from being accidentally cut when using the car charger with the window breaking function. When the car charger with the window breaking function is plugged into the cigarette lighter, the positive contact head 311 is plugged downward, and at this time the notch of the cutting groove 12 will also face downward, so that the blade of the cutting knife 40 can also face downward, so as to further improve the safety performance of the car charger with the window breaking function.

[0055] In the technical solution of the vehicle charger with window breaking function of the utility model, a window breaking assembly is installed in the housing 10. When the vehicle charger with window breaking function needs to be used to break a window, the positive contact head 311 can be pressed against the vehicle window glass and pressure can be applied to the vehicle charger with window breaking function. The positive contact head 311 will shrink into the telescopic hole under the pressure and drive the positive telescopic member 31 to move. The movement of the positive telescopic member 31 will cause the limit transmission member 33 to be separated from the positive telescopic member 31, so that the limit transmission member 33 can move toward the telescopic hole. Under the impact driving force of the driving member 34, the limit transmission member 33 can quickly push the impact member 32 out of the impact channel 313, so that sufficient impact force can be applied to the vehicle window glass abutted by the positive contact head 311, so that the vehicle window glass is broken. Since the impact member 32 hits the vehicle window glass under the action of the driving member 34, there is no need for the user to apply impact force. Therefore, in an emergency, the user can break the vehicle window more timely and conveniently, thereby improving the convenience of using the vehicle charger with window breaking function when breaking the window.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
