DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

The terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances. Furthermore, "multiple" means two or more. In the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0024] The following is combined Figures 1-4 The present invention describes a vehicle emergency safety lock, a vehicle safety system, and a vehicle.

[0025] like Figures 1-3 As shown, the vehicle emergency safety lock provided in this embodiment of the invention includes a latch 11, a lock body 12, and a lock body generator 2. The latch 11 has a locked position and an unlocked position relative to the lock body 12. The lock body generator 2 includes a housing 21, a power assembly 22, a transmission assembly, and a wiring harness connector 24. The power assembly 22 is located inside the housing 21 and includes gunpowder 221, a gas generating agent 222, and a gas blocking element 223. The gas blocking element 223 divides the interior of the housing 21 into a first chamber 201 and a second chamber 202, with the gunpowder 221 and the gas generating agent 222 housed in the sealed first chamber 201. One end of the transmission assembly is located in the second chamber 202 and connected to the gas blocking element 223, while the other end is connected to the latch 11. The wiring harness connector 24 is located in the housing 21, with one end connected to the gunpowder and the other end used for electrical connection to an external power line. When the wire harness connector 24 is energized, the gunpowder 221 can be ignited, causing the gas generator 222 to produce gas. The gas pushes the gas blocking member 223, and the gas blocking member 223 pushes the locking tongue 11 through the transmission assembly, causing the locking tongue 11 to switch from the locked position to the unlocked position.

[0026] The shell 21 is a hollow cavity structure, and the gas barrier 223 is located inside the shell 21, thereby dividing the cavity inside the shell 21 into the first chamber 201 and the second chamber 202. Optionally, the cavity inside the shell 21 is a cylindrical cavity, and the first chamber 201 and the second chamber 202 are arranged along the axial direction of the cylindrical cavity. The gunpowder 221 and the gas generating agent 222 are accommodated in the first chamber 201. The first chamber 201 is further provided with a partition plate, and the gunpowder 221 and the gas generating agent 222 are arranged on the two sides of the partition plate.

[0027] Specifically, referring to Figure 2 The wire harness connector 24 is mounted on the shell 21, one end of which is connected with the gunpowder 221 in the first chamber 201, and the other end of which is located outside the shell 21 and provided with a jack for electrically connecting with an external wire and receiving an external electrical signal.

[0028] When the external wire is powered to the wire harness connector 24, the end of the wire harness connector 24 generates an electric current sufficient to detonate the gunpowder 221. When the gunpowder 221 explodes, it penetrates the partition plate, so that the gas generating agent 222 generates gas by chemical reaction. The gas pushes the gas barrier 223, so that the volume of the first chamber 201 increases and the volume of the second chamber 202 decreases. The gas barrier 223 pushes the transmission assembly, and the transmission assembly pushes the lock tongue 11 to act, so that the lock tongue 11 is ejected from the lock hole, that is, switched from the locking position to the unlocking position.

[0029] The first chamber 201 is a closed chamber to prevent the gas generated by the gas generating agent 222 from leaking into the second chamber 202, and the gas can be stored in the first chamber 201. The gas pushes the transmission assembly and maintains the transmission assembly in the ejected position, so as to keep the lock tongue 11 in the unlocking position.

[0030] Optionally, the gas generating agent 222 can be sodium azide (NaN3), which decomposes to generate nitrogen gas when impacted or heated.

[0031] The vehicle emergency safety lock provided by the embodiment of the present application comprises a lock body generator 2, wherein the lock body generator 2 is internally provided with a power assembly 22, a transmission assembly and a wire harness connector 24; the power assembly 22 is provided with gunpowder 221, a gas generating agent 222 and a gas barrier 223; and the wire harness connector 24 of the lock body generator 2 is connected with external wires. The vehicle emergency safety lock can be used as a door lock or a window lock of a vehicle. The wire harness connector 24 can be electrically connected with an electronic control unit (ECU) of the vehicle, for example, the wire harness connector 24 is electrically connected with an airbag control module. When the vehicle is hit, the airbag control module is triggered and sends an electrical signal to the lock body generator 2 at the same time to detonate the gunpowder 221, so that the gas generating agent 222 generates gas, thereby generating a forced braking force to push the gas barrier 223; the gas barrier 223 pushes the lock tongue 11 to switch from a locking position to an unlocking position through the transmission assembly, thereby forcibly unlocking the lock body and ensuring that the door of the vehicle can be opened when the vehicle is hit.

[0032] In the embodiment of the present application, the gas barrier 223 is a capsule, which is sealingly and fixedly connected with the inner wall of the shell 21, and the capsule and the shell 21 form a closed first chamber 201.

[0033] The capsule is fixedly connected with the inner wall of the shell 21 at the periphery thereof. For example, the shell 21 comprises two shell parts, and the periphery of the capsule is pressed between the two shell parts, thereby forming the first chamber 201 and a second chamber 202 which are independent of each other in terms of gas environment.

[0034] The capsule can be made of a material similar to that of an airbag, has a high tensile strength and can withstand a large pressure during inflation and keep stable in shape. When the gas generating agent 222 generates gas, the capsule expands rapidly, thereby pushing the transmission assembly to move.

[0035] It should be noted that the gas barrier 223 in the embodiment is not limited to the above-mentioned capsule structure, but can also be other structures which can realize sealing of the chamber and push the transmission assembly. For example, the gas barrier 223 can also be a sliding valve, and a cylindrical cavity is formed in the shell 21, and the sliding valve is slidingly and sealingly connected with the inner wall of the cylindrical cavity. The gas generated by the gas generating agent 222 pushes the sliding valve to slide relative to the shell 21, and the sliding valve pushes the transmission assembly.

[0036] In the embodiment of the present application, the power assembly 22 further comprises a plurality of steel balls, which are accommodated in the first chamber 201 and located between the gas generating agent 222 and the capsule. Specifically, a third chamber 203 is formed between the gas generating agent 222 and the gas barrier 223, and the plurality of steel balls are accommodated in the third chamber 203.

[0037] When the gunpowder explodes, the explosion gas generated by the gunpowder pushes the steel ball to fly at a high speed in the direction of the capsule, and a strong impact force is generated. At this time, the steel ball and the gas generated by the gas generating agent 222 jointly act on the capsule, increase the force of the capsule on the transmission assembly, and enable the transmission assembly to smoothly push the lock tongue 11 to unlock.

[0038] As shown in Figure 2 , in the embodiment of the present application, the transmission assembly comprises a first sliding piece 231, and the first sliding piece 231 is in sliding connection with the shell 21. One end of the first sliding piece 231 is located in the shell 21 and connected with the gas barrier piece 223, and the other end is located outside the shell 21 and connected with the lock tongue 11.

[0039] Specifically, the first sliding piece 231 can be a sliding sheet, a sliding block or a sliding rod. The first sliding piece 231 can slide along the arrangement direction of the first chamber 201 and the second chamber 202. One end of the first sliding piece 231 is in contact connection or transmission connection with the gas barrier piece 223 in the shell 21, as long as the gas barrier piece 223 can push the first sliding piece 231 to slide relative to the shell 21 under the action of the gas thrust.

[0040] Optionally, the shell 21 is provided with a first guide groove, and the first sliding piece 231 is slidingly arranged in the first guide groove. The first guide groove is arranged in the interior of the shell 21 and communicates the exterior of the shell 21 with the second chamber 202. The first guide groove is matched in shape with the first sliding piece 231.

[0041] In the case that the gas barrier piece 223 is a sliding valve, since the sliding valve slides linearly in the shell 21 and the direction of the thrust of the sliding valve to the first sliding piece 231 is determined, the first guide groove can not be arranged. In the case that the gas barrier piece 223 is a capsule, since the direction of the thrust of the capsule is uncertain, the sliding of the first sliding piece 231 is guided by arranging the first guide groove, so that the first sliding piece 231 can transmit the force to the lock tongue 11 in the correct direction.

[0042] Further, as shown in Figure 1 , the transmission assembly further comprises a connecting rod 232, and the other end of the first sliding piece 231 is connected with one end of the connecting rod 232, and the other end of the connecting rod 232 is connected with the lock tongue 11.

[0043] Optionally, one of the first sliding piece 231 and the lock tongue 11 is fixedly connected with the connecting rod 232, and the other is detachably connected with the lock tongue 11; or one of the first sliding piece 231 and the lock tongue 11 is detachably connected with the connecting rod 232, and the other is fixedly connected with the lock tongue 11. In this way, the detachable installation of the lock body generator 2 and the lock tongue 11 can be realized, and the lock body generator 2 is convenient to replace.

[0044] The first sliding member 231 has a cross-sectional dimension perpendicular to the sliding direction greater than a cross-sectional dimension of the connecting rod 232, so that the first sliding member 231 has a larger contact area with the gas barrier 223, and the sliding direction of the first sliding member 231 is stable, and the connecting rod 232 with a smaller size is deep into the inside of the lock body 12, and the transmission connection between the first sliding member 231 and the lock bolt 11 is established.

[0045] The vehicle emergency safety lock provided by the embodiment of the application further comprises a second sliding member 13, and the lock body 12 is provided with a second guide groove, and the second sliding member 13 is slidingly arranged in the second guide groove. The two ends of the connecting rod 232 are connected with the first sliding member 231 and the second sliding member 13 respectively. The end of the second sliding member 13 away from the connecting rod 232 is connected with the lock bolt 11, and is used to drive the lock bolt 11 to switch from the locking position to the unlocking position.

[0046] The second sliding member 13 can be a component of the lock body 12, and one end of the second sliding member 13 is connected with the lock bolt 11 in the lock body 12, and the other end of the second sliding member 13 is connected with the connecting rod 232 outside the lock body 12. The second guide groove provides a guide for the movement of the second sliding member 13, and ensures that the second sliding member 13 slides along a fixed direction to push the lock bolt 11 to move.

[0047] In some embodiments, the lock bolt 11 and the lock body 12 are slidingly connected, and the second sliding member 13 is used to push the lock bolt 11 to move along a fixed sliding channel relative to the lock body 12, so as to switch the lock bolt 11 from the locking position to the unlocking position.

[0048] In some other embodiments, the lock bolt 11 and the lock body 12 are rotatably connected, and the second sliding member 13 is used to push the lock bolt 11 to rotate relative to the lock body 12 around the rotating shaft 14, so as to switch the lock bolt 11 from the locking position to the unlocking position.

[0049] Optionally, the two ends of the connecting rod 232 are rotatably connected with the first sliding member 231 and the second sliding member 13 respectively. For example, the two ends of the connecting rod 232 are hingedly connected with the first sliding member 231 and the second sliding member 13 respectively. In this way, the transmission between the first sliding member 231 and the second sliding member 13 is more flexible, and the sliding of the first sliding member 231 and the second sliding member 13 is more smooth. When the impact load of the gas barrier 223 is borne, the connection structure can effectively reduce the stress and deformation caused by external force, and improve the stability of the structure.

[0050] In the embodiment of the application, as shown in Figure 4 The vehicle emergency safety lock further comprises an electromagnetic actuator 25 and a transmission member 26.

[0051] The transmission member 26 is connected with the lock bolt 11, and when the electromagnetic actuator 25 receives a trigger signal, an electromagnetic force is generated to drive the transmission member 26 to push the lock bolt 11, so that the lock bolt 11 is switched from the locking position to the unlocking position.

[0052] As a supplement to the lock body 12 generator, the electromagnetic actuator 25 of the present embodiment can also generate an electromagnetic force to push the lock bolt 11 to unlock upon receiving a trigger signal. That is, the electromagnetic actuator 25 provides a second unlocking approach for the vehicle emergency safety lock. Specifically, the transmission member 26 can be a push rod.

[0053] It should be noted that the present embodiment adopts a hierarchical response strategy for the lock body 12 generator and the electromagnetic actuator 25. Upon receiving a trigger signal, the vehicle emergency safety lock first attempts to start the electromagnetic actuator 25, which responds faster and is lossless. If the electromagnetic actuator 25 fails to successfully unlock due to mechanical jamming or power shortage, etc., the lock body 12 generator will be immediately started as the final guarantee to forcibly break and unlock. This design takes into account both response speed and reliability in extreme cases.

[0054] The electromagnetic actuator 25 and the lock body 12 generator are designed redundantly as double driving units. The lock body 12 generator is a blasting unlocking device based on the power assembly 22, which has strong power and can overcome mechanical resistance caused by large deformation. The transmission member 26 is a fast unlocking device based on the electromagnetic actuator 25, which responds quickly and can be repeatedly tested.

[0055] In the present embodiment, as shown in Figure 4 The vehicle emergency safety lock of the present embodiment further includes an ejection mechanism 27.

[0056] The ejection mechanism 27 is connected to the vehicle door and exerts an ejection force on the vehicle door when the lock bolt 11 is switched to the unlocking position.

[0057] In order to further improve the escape efficiency, the present embodiment provides the ejection mechanism 27. The ejection mechanism 27 will give an initial outward pushing force to the vehicle door at the moment when the vehicle lock is forcibly unlocked, helping to overcome the opening resistance caused by door frame deformation or external pressure (such as water pressure), especially when the vehicle door is slightly deformed or the person inside the vehicle cannot push the vehicle door, which can effectively create escape space.

[0058] In some embodiments, the ejection mechanism 27 includes a spring, a release claw, and an ejection rod. The release claw is fixed on the lock bolt 11 by buckling, the release claw is connected with the spring, and the spring is in abutment with the ejection rod. The spring is in a compressed state, and when the lock bolt 11 is switched to the unlocking position, the release claw is driven to release, thereby releasing the elastic potential energy of the spring, and the spring pushes the ejection rod to push the vehicle door outward by a distance.

[0059] In the present embodiment, as shown in Figure 4 The vehicle emergency safety lock of the present embodiment further includes a manual trigger switch 28.

[0060] The manual trigger switch 28 is arranged on the lock body 12 and is used to receive an emergency operation signal of the person in the vehicle, so as to switch the lock bolt 11 from the locking position to the unlocking position.

[0061] When the vehicle encounters an emergency situation and the person in the vehicle needs to get off immediately, the person in the vehicle presses the manual trigger switch 28 to switch the lock bolt 11 to the unlocking position, and the manual trigger switch 28 can provide the person in the vehicle with an active survival option when the person is conscious but cannot open the door normally.

[0062] The embodiment of the present application also provides a vehicle safety system, which comprises a sensor, a safety airbag control module and the vehicle emergency safety lock in any of the above embodiments.

[0063] When the vehicle collides, the sensor detects a collision signal and sends the signal to the safety airbag control module.

[0064] The safety airbag control module 400 of the embodiment is also electrically connected with the electromagnetic actuator 25, the ejection mechanism 27 and the manual trigger switch 28. As shown in the figure, the sensor 300 of the embodiment comprises a collision sensor 301, a water immersion sensor 302 and a high-temperature sensor 303. Figure 4

[0065] The collision sensor 301 is used to collect the collision signal of the vehicle, the water immersion sensor 302 is used to determine whether the vehicle is in water, and the high-temperature sensor 303 is used to collect whether the temperature in the vehicle is too high to exceed the normal operating temperature.

[0066] The embodiment of the present application also provides a vehicle, which comprises a vehicle window, a vehicle door and the vehicle safety system in any of the above embodiments.

[0067] ​It should be pointed out finally that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the same; and although the present application has been described in detail with reference to the foregoing embodiments, it should be appreciated by those skilled in the art that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features thereof can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
