For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0045] Unless otherwise specified, the front-back direction in this application refers to the longitudinal direction of the vehicle, i.e., the X direction; the left-right direction refers to the lateral direction of the vehicle, i.e., the Y direction; and the up-down direction refers to the vertical direction of the vehicle, i.e., the Z direction.

[0046] The following is for reference. Figures 1-4 An emergency switch mechanism according to an embodiment of the present invention is described. This emergency switch mechanism enables rapid and automatic execution of the actuator in the event of a collision or accident, thereby protecting the safety of personnel or equipment, enabling rapid rescue of personnel, and has a wide range of applications and low cost.

[0047] like Figures 1-4 As shown, an emergency switch mechanism according to an embodiment of the present invention includes: a triggering structure and a driving structure.

[0048] One end of the trigger structure is connected to the driver structure, and the other end of the driver structure is suitable for connection to the execution structure.

[0049] Specifically, the triggering structure can be triggered. When the triggering structure is activated, the triggering mechanism will transmit power or signals to the driving structure to drive the driving structure to move or perform actions. When the driving structure moves, it can transmit power or signals to the execution structure to drive the execution structure to move. Thus, the power transmission between the triggering structure, the driving structure and the execution structure can be realized.

[0050] After the emergency switch mechanism collides, the triggering structure triggers the driving structure, which in turn drives the execution structure to move.

[0051] In other words, the triggering structure is only activated after a collision occurs in the emergency switch mechanism. This triggering structure can be an acceleration sensor, pressure sensor, or trigger switch, etc., to detect the collision or impact and thus trigger it. The drive structure receives the signal or power transmitted by the triggering structure and initiates movement. It then transmits this power to the actuator structure to drive it to perform corresponding movements. For example, the actuator structure can unlock, cut off power, turn on a switch, or activate other mechanisms. This enables the emergency switch mechanism to perform emergency operations in the event of a collision or other emergency. Specifically, it allows for rapid and automatic execution of the actuator structure in the event of a collision or accident, protecting personnel and equipment, facilitating rapid rescue, and offering wide applicability and low cost.

[0052] According to an embodiment of the present invention, the emergency switch mechanism is provided with a triggering structure to trigger the driving structure after a collision, thereby driving the execution structure to move. This enables the execution structure to be executed quickly and automatically in the event of a collision or accident, thereby protecting the safety of personnel or equipment, enabling rapid rescue of personnel, and has a wide range of applications and low cost.

[0053] In some embodiments, the triggering structure 31 includes a trigger element 311 and a trigger switch 312. The trigger element 311 is movable relative to the trigger switch 312. The trigger element 311 is configured to contact the trigger switch 312 and turn on the trigger switch 312 after a collision. The trigger switch 312 is configured to trigger the driving structure 32 after being turned on.

[0054] In other words, when the emergency switch mechanism does not collide, the trigger 311 and the trigger switch 312 are spaced a certain distance apart and do not contact each other. The trigger switch 312 is in a non-conductive state. However, after the emergency switch mechanism collides, the trigger 311 moves relative to the trigger switch 312 and approaches the trigger switch 312 to make contact with it. At this time, the trigger switch 312 is turned on, and the trigger switch 312 can trigger the drive structure 32 to move, so that the drive structure 32 can drive the actuator structure to move.

[0055] In some embodiments, the trigger switch 312 includes two spaced contacts 3121, a trigger member 311 is spaced apart from the two contacts 3121, and the trigger member 311 contacts the two contacts 3121 after a collision to turn on the trigger switch 312.

[0056] Specifically, such as Figure 4 As shown, the trigger switch 312 includes two spaced contacts 3121, as... Figure 4 As shown in the vertical direction, the two contacts 3121 are spaced apart by a certain distance along the vertical direction, meaning that the two contacts 3121 are not in contact and connected, and the trigger switch 312 is in the open state. Figure 4 As shown in the left-right direction, the trigger 311 is located to the left of the two contacts 3121 and is spaced a certain distance away from the two contacts 3121, and is not in contact with the two contacts 3121 to ensure that the circuit is in an open state.

[0057] After a collision occurs in the emergency switch mechanism, the trigger 311 is triggered to move to the right to contact the two contacts 3121 so that the trigger switch 312 is turned on, thereby connecting the circuit. At this time, the trigger switch 312 can trigger the drive structure 32 to move.

[0058] In practice, when emergency switch mechanisms are used in vehicles, Figure 4 The front-back direction shown is the vehicle's driving direction. When the vehicle collides and decelerates to a certain value, the trigger 311 will deform or displace to contact the two contacts 3121, thereby forming a conductive path. This enables the trigger switch 312 to be turned on, which in turn triggers the drive structure 32 to move and drive the execution structure to move, thus realizing the automatic execution of the execution structure.

[0059] In some embodiments, contact 3121 is configured as resilient contact 3121.

[0060] Specifically, the elastic contact 3121 can undergo a certain degree of deformation, which allows the contact 3121 to deform when subjected to external force and return to its original shape when the external force is removed. This enables the contact 3121 to automatically adjust its position when in contact with the trigger 311, allowing the trigger 311 to better contact and press against the contact 3121, improving the adaptability and durability of the contact 3121 and the reliability of the conducting circuit, and avoiding the failure of the trigger switch 312 to conduct due to poor contact.

[0061] In some embodiments, one end of contact 3121 is connected to trigger switch 312, and the other end of contact 3121 is used to make elastic contact with trigger 311.

[0062] Specifically, such as Figure 4 As shown, contact 3121 is constructed as an inclined, elastic contact 3121, and the right end of contact 3121 is connected to trigger switch 312.

[0063] In practice, when the emergency switch mechanism does not collide, the right end of contact 3121 is connected to the trigger switch 312, and the left end of contact 3121 is not in contact with the trigger element 311. When the emergency switch mechanism collides, the trigger element 311 moves to elastically contact the left end of contact 3121. At this time, the elastic contact 3121 can deform to ensure the best contact effect, ensuring that the trigger switch 312 is turned on. At the same time, it also absorbs and reduces the impact force to a certain extent, reduces the risk of damage to contact 3121, and improves its service life.

[0064] When an emergency switch mechanism is used in a vehicle Figure 4 The front-back direction shown is the vehicle's driving direction. When the vehicle is in normal driving state, the left end of the contact 3121 is not in contact with the trigger 311. However, when the vehicle collides and decelerates to a certain value, the trigger 311 can move to elastically contact the left end of the contact 3121.

[0065] In some embodiments, such as Figure 4 As shown, the trigger structure 31 also includes a trigger housing 313, in which the trigger element 311 and the trigger switch 312 are both installed. This protects the trigger element 311 and the trigger switch 312 from damage, and also prevents dust, moisture, etc. from affecting the trigger element 311 and the trigger switch 312.

[0066] In some embodiments, such as Figure 4 As shown, a rolling groove 3131 is formed inside the trigger housing 313, and the trigger member 311 is adapted to move within the rolling groove 3131.

[0067] In other words, the rolling groove 3131 should be adapted to the shape and structure of the trigger 311 so that the trigger 311 can move within the rolling groove 3131. For example, it can slide or roll within the rolling groove 3131, thereby enabling the trigger 311 to contact the contact point 3121.

[0068] In some embodiments, such as Figure 4 As shown, the trigger element 311 is constructed as a rolling ball, which rolls along the rolling groove 3131 towards the right, closer to the trigger switch 312. That is, the shape and size of the rolling groove 3131 should match the shape and size of the rolling ball so that the rolling ball can roll stably along the rolling groove 3131. It can be understood that the extending direction of the rolling groove 3131 is the rolling direction of the rolling ball. Figure 4In the left and right direction of the emergency switch mechanism, when the emergency switch mechanism is applied in a vehicle, the extension direction of the rolling groove 3131 is the driving direction of the vehicle, that is, the front and back direction of the vehicle. In this way, when the vehicle collides and the vehicle decelerates to a certain value, the rolling ball can be made to roll forward along the rolling groove 3131 towards the trigger switch 312 under the action of the vehicle's inertial force, so as to contact the contact 3121 and realize the conduction of the trigger switch 312.

[0069] Thus, the rolling ball within the rolling groove 3131 activates the switch 312, making it easier to activate the switch through the rolling motion, thereby improving the sensitivity and accuracy of the activation.

[0070] In practical design, the rolling ball can be constructed as a steel ball, and a permanent magnet can be provided so that when the emergency switch mechanism does not collide, the rolling ball is attracted by the specific magnetic force applied by the permanent magnet and thus fixed in the rolling groove 3131 at the end away from the trigger switch 312. When the emergency switch mechanism collides, the steel ball can break free from the specific magnetic force applied by the permanent magnet under the action of the inertial force after the collision and continue to move forward along the rolling groove 3131 until it contacts the contact 3121 and turns on the trigger switch 312.

[0071] In some embodiments, such as Figure 2 and Figure 3 As shown, the drive structure 32 includes a drive component 321 and a transmission component. After being triggered, the drive component 321 drives the transmission component to push the execution structure to move.

[0072] In other words, when the emergency switch mechanism is involved in a collision, the triggering structure triggers the drive component 321. After being triggered, the drive component 321 can transmit its power to the transmission component to drive the transmission component to move. In turn, when the transmission component moves, it can push the actuator to move. Thus, the power transmission from the drive component to the actuator is realized, and the movement of the actuator is realized. This is flexible, convenient, and highly reliable.

[0073] In some embodiments, the drive element 321 is configured as a gas generator, which ignites when the trigger structure 31 is turned on to generate an impact force to output a driving force to the transmission component.

[0074] In other words, when the emergency switch mechanism is collided, the triggering structure 31 is triggered and connected, the gas generator will be ignited and a large amount of gas will be generated rapidly. This gas will expand rapidly in the enclosed space, thereby generating a huge impact force. This impact force will be transmitted to the transmission component to drive the transmission component to move, and then drive the actuator to move.

[0075] Therefore, by generating a huge impact force in a very short time through the gas generator to output driving force to the transmission components, the entire drive structure 32 can quickly respond to the trigger signal and achieve rapid action, thereby realizing the rapid execution of the actuator, which is beneficial for rapid rescue of personnel or emergency stop of equipment.

[0076] In some embodiments, the transmission component includes a drive arm 323 and at least one transmission member, wherein the at least one transmission member is poweredly connected between the drive member 321 and the drive arm 323 to drive the drive arm 323 to move, and the drive arm 323 pushes the execution structure to move when it moves.

[0077] The number of transmission components can be set to one, two or more. Setting multiple transmission components can improve the smoothness of power transmission. One of the transmission components is connected between the drive component 321 and the drive arm 323 to transmit the driving force output by the drive component 321 to the drive arm 323, thereby driving the drive arm 323 to move. The drive arm 323 is connected to the actuator so that it can drive the actuator to move when the drive arm 323 moves.

[0078] In some embodiments, the drive arm 323 is configured to be rotatable, so that when the transmission member transmits power to the drive arm 323, the drive arm 323 can rotate, and when the drive arm 323 rotates, it can drive the actuator to move.

[0079] Therefore, the rotation of the drive arm 323 achieves the pushing effect on the actuator, which improves the reliability of the actuator's movement, and the rotational movement is smooth, reliable, and easy to implement.

[0080] In some embodiments, there are two transmission components, namely push rod 3221 and slider 3222. One end of push rod 3221 is connected to drive component 321 and the other end is connected to slider 3222. Push rod 3221 drives slider 3222 to drive drive arm 323 to move.

[0081] Specifically, such as Figure 2 and Figure 3 As shown, there are two transmission components, namely push rod 3221 and slider 3222. Both push rod 3221 and slider 3222 are as follows: Figure 2 As shown, extending in the left and right direction, the right end of the push rod 3221 is connected to the drive member 321, and the left end is connected to the slider 3222, so that the drive member 321 can transmit power to the push rod 3221, thereby the push rod 3221 can push the slider 3222 to move horizontally. During the sliding motion, it drives the drive arm 323 to move, so that the drive arm 323 pushes the actuator to move.

[0082] Thus, the power of the drive component 321 is transmitted to the drive arm 323 through the transmission component composed of the push rod 3221 and the slider 3222, thereby realizing the movement of the actuator. The structure is simple and compact, which improves the integration of the emergency switch mechanism.

[0083] In some embodiments, one of the slider 3222 and the drive arm 323 is provided with a push recess 3222a and the other is provided with a push engagement protrusion 3231. That is, the push recess 3222a can be provided on the slider 3222 and the push engagement protrusion 3231 can be provided on the drive arm 323, or the push engagement protrusion 3231 can be provided on the slider 3222 and the push recess 3222a can be provided on the drive arm 323.

[0084] like Figure 2 As shown, a push recess 3222a is formed at the left end of the slider 3222, and a push engagement protrusion 3231 is formed at the lower end of the drive arm 323. The push recess 3222a and the push engagement protrusion 3231 are adapted to each other. The push engagement protrusion 3231 is located inside the push recess 3222a and presses against the inner wall of the push recess 3222a. Thus, when the slider 3222 is pushed to the left by the push rod 3221, the slider 3222 can drive the drive arm 323 to rotate by the engagement of the push recess 3222a and the engagement protrusion, thereby realizing the power transmission from the push rod 3221 to the drive arm 323.

[0085] Therefore, by pushing the notch 3222a to engage with the protrusion, a stable connection between the slider 3222 and the drive arm 323 is ensured, so that the driving force can be transmitted more effectively from the slider 3222 to the drive arm 323, thereby improving the reliability and stability of power transmission.

[0086] In some embodiments, the execution structure is configured as a door handle 2.

[0087] In other words, when the emergency switch mechanism is involved in a collision, the triggering structure 31 is triggered, which in turn triggers the driving structure 32, causing the driving structure 32 to move the door handle 2, thereby popping out or opening the door handle 2.

[0088] The present invention also proposes a door handle assembly 100.

[0089] According to an embodiment of the present invention, a door handle assembly 100 includes a door handle 2 and an emergency switch mechanism. The door handle 2 is configured as an actuating structure, and the emergency switch mechanism is the emergency switch mechanism in any of the above embodiments. The emergency switch mechanism is connected to the door handle 2.

[0090] The door handle assembly in this embodiment can be a door handle assembly 100 for vehicles, ships, aircraft, etc.

[0091] Specifically, when the door handle assembly 100 is impacted, the triggering structure 31 is triggered, which in turn triggers the driving structure 32, causing the driving structure 32 to move the door handle 2, thereby enabling the door handle 2 to open automatically, facilitating external personnel to open the car door, thus improving safety in emergency situations such as collisions of vehicles, ships, and aircraft, and ensuring that internal personnel can be quickly rescued.

[0092] Therefore, by opening the door handle 2 through the emergency switch mechanism in emergency situations such as collisions, the rescue time is greatly shortened and the safety is improved.

[0093] In some embodiments, the door handle assembly 100 further includes a handle base 1, to which the door handle 2 is movably mounted.

[0094] Specifically, the handle base 1 is used to fix and install the door handle 2. When the door handle assembly 100 is the door handle assembly 100 on the vehicle, it can be fixedly installed on the outer panel 91 of the door to provide a stable mounting point for the door handle 2. The following explanation uses the door handle assembly 100 on the vehicle as an example.

[0095] like Figure 1 and Figure 3 As shown, the door handle 2 is a component used by the user to open the car door. The door handle 2 is movably mounted on the handle base 1, that is, the door handle 2 can move relative to the handle base 1. For example, the door handle 2 can move away from the handle base 1 and extend out of the surface of the outer door panel 91 to open the door handle 2 so that the user can hold the door handle 2 to open the car door, or the door handle 2 can be brought close to and retracted to the handle base 1 and flush with the surface of the outer door panel 91 to hide the door handle 2 and maintain aesthetics. In actual design, a decorative cover 92 can be provided on the outside of the door handle 2 to decorate the door handle 2. When the door handle 2 is in the hidden state, the decorative cover 92 is flush with the outer door panel 91.

[0096] It should be noted that when a vehicle is involved in a collision or other accident, the occupants may be unconscious and in a dangerous state due to the excessive impact. At this time, rescuers urgently need to open the car door from the outside to carry out the rescue, but the door handle 2 is still in a hidden state (i.e. the outer handle has not popped out), which delays the golden rescue time. Therefore, the door handle assembly 100 needs to have the function of automatically popping out the outer handle after a collision. The emergency switch mechanism can be used to solve this problem. That is, the emergency switch mechanism can realize the automatic pop-out of the door handle 2 when the vehicle is involved in a collision or other accident.

[0097] In practice, when a vehicle collides and its speed decelerates to a certain value, the triggering structure 31 is triggered, which in turn triggers the driving structure 32, causing the driving structure 32 to move the door handle 2. This causes the door handle 2 to extend relative to the handle base 1, thereby enabling the door handle 2 to automatically pop out, i.e., to be exposed outside the door panel 91. This makes it easier for people outside the vehicle to open the door, thereby improving safety in emergency situations such as vehicle collisions and ensuring that people inside the door can be rescued quickly.

[0098] Therefore, during normal vehicle operation, the door handle 2 is hidden under the decorative cover 92. Only in an emergency will the door handle 2 pop out and push the decorative cover 92 out, revealing it outside the door panel 91, making it convenient for people outside the vehicle to open the door, which is safe and effective.

[0099] In some embodiments, such as Figure 2 As shown, the door handle assembly 100 also includes an elastic element 4, which has a certain elastic force. The elastic element 4 is installed on the handle base 1. The elastic element 4 is used to apply an elastic force to the door handle 2 in the opposite direction to the driving force of the drive structure 32, so that the door handle 2 is in a balanced state and cannot move.

[0100] Therefore, through the elastic force of the elastic element 4, the door handle 2 will not move away from the handle base 1 when the vehicle is driving normally and no other external force is applied, thus keeping it hidden inside the outer panel 91 of the door and ensuring that the door handle 2 will not be opened accidentally.

[0101] In actual design, the elastic element 4 can be set as a spring, torsion spring, elastic sheet, etc., and can be flexibly selected according to the actual situation.

[0102] In some embodiments, the door handle 2 is provided with a push part 5, and the drive structure 32 and the elastic member 4 press against both sides of the push part 5.

[0103] Specifically, such as Figure 2 and Figure 3 As shown, the door handle 2 is a side-rotating pop-out door handle 2. The door handle 2 is provided with a push part 5. The drive structure 32 presses against the right side of the push part 5, and the elastic member 4 presses against the left side of the push part 5. Thus, the push part 5 is fixed and cannot move, and the door handle 2 is sandwiched between the elastic member 4 and the drive structure 32. That is, the door handle 2 is fixed and cannot move by the elastic member 4 and the drive structure 32. Therefore, under normal driving conditions of the vehicle, that is, when there is no collision, the movement of the door handle 2 is restricted and hidden inside the outer door panel 91.

[0104] In practice, such as Figure 2As shown, a pressing protrusion 3232 can be provided at the middle position of the side of the drive arm 323 facing the push part 5. The pressing protrusion 3232 presses against the right side of the push part 5. The elastic member 4 is constructed as a torsion spring, and the upper side of the torsion spring presses against the left side of the push part 5, thereby clamping the push part 5 between the drive arm 323 and the torsion spring, ensuring that it cannot move. A fixed bracket can also be provided so that the lower end of the torsion spring can be placed at the opening of the fixed bracket to abut against it, thereby ensuring the stability of the torsion spring and its rotatability when the door handle 2 is subjected to the force of the drive arm 323.

[0105] In some embodiments, the door handle assembly 100 also includes a pull cable 7, and the door handle 2, after being extended relative to the handle base 1, is adapted to actuate the pull cable 7 to unlock the door.

[0106] Specifically, when a vehicle collision occurs and the vehicle speed decelerates to a certain value, and the drive arm 323 rotates, the drive arm 323 will push the door handle 2 so that the door handle 2 extends relative to the handle base 1, so that the door handle 2 is in the pop-out state. After the vehicle collision ends, the transmission component can maintain the driving force under the pressure of the gas inside the gas generator, that is, resist the drive arm 323, so that the door handle 2 remains in the pop-out state.

[0107] At this time, the door handle 2 can be switched from the pop-out state to the open state. A certain pulling force can be applied to the door handle 2 from the outside, so that it continues to rotate a certain angle towards the outer door panel 91, thereby driving the pull cable 7 to move to open the door lock. In this way, the door is unlocked and people outside can open the door from the outside.

[0108] In some embodiments, such as Figures 1-3 As shown, the door handle assembly 100 also includes a zipper block 6, which is rotatably mounted on the handle base 1, meaning that the zipper block 6 can rotate relative to the handle base 1.

[0109] Furthermore, such as Figure 2 As shown, the zipper cable 7 is connected to the zipper block 6. The zipper cable 7 is used to unlock the car door. The zipper block 6 presses against the door handle 2 and is located above the front side of the handle body. The door handle 2 is adapted to push the zipper block 6 to move so as to drive the zipper cable 7 to move.

[0110] Specifically, after the door handle 2 extends relative to the handle base 1, i.e. when the door handle 2 is in the pop-out state, a certain pulling force can be applied to the door handle 2 from the outside of the car door so that the door handle 2 can continue to rotate a certain angle towards the outer panel 91 of the car door. That is, the user can pull the door handle 2, which can drive the pull lock block 6 to move. When the pull lock block 6 moves, it will drive the pull lock cable 7 to move together. Thus, the movement of the pull lock cable 7 will eventually be transmitted to the car door lock mechanism, triggering the lock opening mechanism, thereby realizing the opening of the car door.

[0111] Therefore, by pressing the zipper block 6 against the door handle 2, after the door handle 2 is in the pop-out state, the user can continue to manually pull the door handle 2 to drive the zipper block 6 to move, so that the door handle 2 switches from the pop-out state to the open state, thereby unlocking and opening the car door. This provides a mechanical unlocking function that is flexible and convenient, does not require electric drive, and greatly saves costs.

[0112] In some embodiments, such as Figure 2 As shown, the handle base 1 is also provided with a lock cylinder mounting hole 11, and a door lock cylinder is installed at the lock cylinder mounting hole 11.

[0113] In other words, the lock cylinder mounting hole 11 should be compatible with the shape and size of the door lock cylinder, so that the door lock cylinder can be stably installed in the lock cylinder mounting hole 11. The door lock cylinder can receive the key and control the extension and retraction of the bolt, thereby realizing the locking and unlocking of the door.

[0114] Therefore, by setting the lock cylinder mounting hole 11 and installing the door lock cylinder in the lock cylinder mounting hole 11, it can be ensured that the door cannot be easily opened when locked, and the door security can be further improved by inserting the key into the door lock cylinder and rotating it when the electro-locking fails.

[0115] In some embodiments, the door lock cylinder is provided with a keyhole for inserting a key.

[0116] In other words, the keyhole is adapted to the shape and size of the key used for unlocking, so that the key can be smoothly inserted into the door lock cylinder and turned, interacting with the internal mechanical structure of the lock cylinder to realize the extension and retraction of the bolt, thereby locking or unlocking the door.

[0117] Therefore, if electrolytic unlocking fails, the door can be unlocked by inserting the key into the ignition and rotating it, thus further enhancing the door's security.

[0118] The present invention also proposes a vehicle.

[0119] The vehicle according to an embodiment of the present invention includes the door handle assembly 100 of any of the above embodiments.

[0120] According to the vehicle of the present invention, by setting the above-mentioned door handle assembly 100, after a vehicle collision, the triggering structure 31 can trigger the driving structure 32 and cause the driving structure 32 to drive the door handle 2 to extend relative to the handle base 1, thereby realizing the automatic pop-out of the door handle 2, which makes it easier for people outside the vehicle to open the door, thereby improving safety in emergency situations such as vehicle collisions, ensuring that people at the door can be rescued quickly, with a wide range of applications and low cost.

[0121] Since the door handle 2 pops out automatically via mechanical transmission without the need for electric drive, it greatly saves costs. It also has a simple structure, reasonable layout, and makes effective use of fragmented space inside the vehicle, occupying less installation space and thus providing more space for the installation of other vehicle components.
