Abstract

The utility model discloses a collision unlocking mechanism of a hidden type door handle and the hidden type door handle. The hidden type door handle comprises a handle concave part and a handle body, wherein the handle concave part is arranged on a vehicle door in a concave mode, and the handle body is movably arranged in a containing cavity of the handle concave part. The collision unlocking mechanism comprises an inertia unlocking assembly and a limiting blocking assembly which are movably arranged on the inner side of the containing cavity. When the handle body is in a closed state, the inertia unlocking assembly is in an initial state, and the blocking end of the limiting blocking assembly abuts against one side of the inertia unlocking assembly.

Rescue workers can open the automobile door in time from the outside to help people in the automobile escape, and the safety of the automobile is improved.

Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a collision unlocking mechanism for a concealed door handle, which can be applied to the concealed door handle of an automobile. Background Technology

[0002] With the development of new energy vehicles, major manufacturers are paying more attention to the technological sophistication and aesthetics of automobiles. Hidden door handles reduce protruding parts on the vehicle body, lower wind resistance, increase driving range, and thus improve the vehicle's aerodynamic performance. They also make the car's appearance cleaner and more modern, increasing its refinement and luxury. Furthermore, the welcoming function of hidden door handles provides customers with a better sense of ceremony. Therefore, hidden door handles are being used in an increasing number of car models.

[0003] With the widespread use of concealed door handles, the resulting safety concerns are increasingly attracting attention from the industry and regulatory authorities, especially in certain special situations where concealed door handles are needed to easily open the car door. For example, after a collision, the concealed handle must be able to unfold promptly to ensure the safety of the occupants. However, existing models or concealed door handle solutions generally rely on an additional backup power supply to the vehicle. After a collision, the backup power supply can provide power to electrically unfold the concealed handle. But in emergency situations such as collisions, or when the backup power supply fails or runs out of power, the concealed door handle is unlikely to open automatically to unlock the door.

[0004] Therefore, in the case of emergency such as a collision or when there is a power outage due to a failure of the backup power supply or a lack of power, the existing concealed door handles may not be able to open automatically. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the prior art, when a hidden door handle is involved in an emergency such as a collision or when the backup power supply is damaged or the power is depleted, the door handle cannot be opened automatically.

[0006] To solve the above problems, this utility model provides a collision unlocking mechanism for a concealed door handle. The concealed door handle includes a handle recess recessed on the car door and a handle body movably disposed in a receiving cavity within the handle recess. The handle body can switch between a closed state and an open state. When the handle body is in the closed state, the outer wall of the handle body is flush with the outer surface of the car door. When the handle body is in the open state, the handle body is at least partially exposed on the outer surface of the car door.

[0007] Furthermore, the collision unlocking mechanism includes an inertial unlocking component and a limiting blocking component movably disposed inside the receiving cavity; wherein, when the handle body is in the closed state, the inertial unlocking component is in the initial state, and the blocking end of the limiting blocking component abuts against one side of the inertial unlocking component; and, when the door is impacted, the inertial unlocking component rotates towards one side of the handle body under inertial force, pushing the handle body relative to the handle recess to switch to the open state, the inertial unlocking component switches from the initial state to the unlocked state, and the blocking end of the limiting blocking component abuts against the other side of the inertial unlocking component and keeps the inertial unlocking component in the unlocked state.

[0008] Using the above technical solution, when a car accident occurs and the door is impacted, the inertial unlocking component is subjected to inertial force, causing it to rotate or translate towards one side of the handle body. This pushes the handle body relative to the handle recess from a closed state to an open state, allowing at least part of the handle body to protrude from the outer surface of the door. At this time, the inertial unlocking component switches from its initial state to an unlocked state. Due to the inertial force, the inertial unlocking component rotates or moves towards one side of the handle body, and the position of the blocking end of the limiting blocking component on the inertial unlocking component changes. In the initial state, the blocking end of the limiting blocking component abuts against one side of the inertial unlocking component, but now abuts against the other side, thus keeping the inertial unlocking component unlocked. At this time, if the occupants are unconscious due to the impact, rescuers outside the vehicle can quickly open the door using the handle body for rescue; or, if the occupants are not unconscious and can move freely, they can push the door open themselves to quickly escape the accident scene.

[0009] In summary, the advantages of this concealed door handle collision unlocking mechanism are that when the car door or the side of the car is hit, the concealed door handle can unlock the door in time through the collision unlocking mechanism, which is conducive to rescuers opening the door from the outside to rescue the people inside the car, or the people inside the car can also push open the door in time to escape from the car while they are conscious, thus ensuring the safety of the people inside the car and improving the safety of the car.

[0010] Furthermore, in one embodiment, the inertial unlocking assembly includes an unlocking component movably disposed inside the receiving cavity, and the limiting blocking assembly includes a mounting base fixedly disposed inside the unlocking component, and a limiting component with one end fixedly mounted on the mounting base and the other end abutting against the unlocking component.

[0011] When the unlocking component is in its initial state, the limiting component has a preload, which causes the limiting component to have a preload on the unlocking component. This ensures that the unlocking component will not enter the unlocking state when the door or side of the car is slightly tapped, thus guaranteeing the reliability of the unlocking component's operation. Furthermore, when the unlocking component is in the unlocking state, the other end of the limiting component abuts against the corresponding side of the unlocking component under the action of the preload.

[0012] Alternatively, when the unlocking component is in the initial state, there is an adhesive force between the other end of the limiting component and one side of the unlocking component, and when the unlocking component is in the unlocked state, there is an adhesive force between the other end of the limiting component and the other side of the unlocking component.

[0013] By adopting the above technical solution, when the unlocking component switches from the initial state to the unlocked state, the adsorption position between the other end of the limiting component and the unlocking component is changed during this process, ensuring the accuracy of the unlocking component switching from the initial state to the unlocked state.

[0014] Furthermore, in one embodiment, the unlocking component includes a rotating shaft disposed inside the receiving cavity and an inertial block rotatably disposed on the rotating shaft; wherein a pushing part is disposed on the side of the inertial block away from the rotating shaft, and the center of mass of the inertial block is located on the outer periphery of the pushing part away from the rotating shaft.

[0015] When the car door is hit, the inertial block rotates towards the handle body due to inertial force, and the pushing part at one end of the pushing part pushes the inner wall of the handle and the handle body switches to the open state relative to the handle recess.

[0016] Using the above technical solution, when a car accident occurs and the door or side of the car is hit, the inertial block rotates towards the handle body due to inertial force. At this time, the end of the push part pushes the inner wall of the handle body, and the handle body switches to the open state relative to the handle recess. Furthermore, since the center of mass of the inertial block is located on the outer periphery of the push part away from the axis of rotation, when the inertial block is subjected to inertial force, it can quickly rotate around the axis of rotation and push the handle body to the open state through the end of the push part. Then, the handle body is kept in the open state by the limiting component.

[0017] Furthermore, in one embodiment, the unlocking component includes a slide rail disposed inside the receiving cavity and a movable block disposed on the slide rail, the movable block being translatably disposed on the slide rail.

[0018] The movable block has a pushing part on the side near the handle body. When the door is hit, the movable block moves towards the side of the handle body due to inertial force, and the pushing end of the pushing part pushes the inner wall of the door handle and the handle body switches to the open state relative to the handle recess.

[0019] Using the above technical solution, when the door or side of the car is impacted, the moving block moves towards one side of the handle body due to inertial force. At this time, the pushing end of the pushing part pushes the inner wall of the handle body and links the handle body to switch from the closed state to the open state relative to the handle recess. Furthermore, since the moving block can be slidably mounted on the slide rail, it can quickly move along the slide rail under inertial force, thereby pushing the handle body into the open state. It should be understood that a limiting area is also provided on the moving block. When the pushing part of the moving block pushes the handle body into the open state, the other end of the limiting component abuts against the limiting area.

[0020] Furthermore, in one embodiment, the limiting component includes a sleeve with one end fixedly mounted to the mounting base and the other end extending toward the unlocking component, and an elastic push head disposed within the sleeve, the elastic push head being switchable between a compressed state and an extended state relative to the sleeve.

[0021] When the unlocking component is in the initial state, the elastic push head is compressed relative to the sleeve and has a pre-tightening force, and the end of the elastic push head away from the mounting base abuts against one side of the unlocking component; when the unlocking component is in the unlocked state, the elastic push head extends out of the sleeve under the action of the pre-tightening force, and the end of the elastic push head away from the mounting base abuts against the other side of the unlocking component.

[0022] Specifically, when the unlocking component is in its initial state, the elastic pusher is compressed relative to the sleeve and has a pre-tightening force. The end of the elastic pusher away from the mounting seat abuts against one side of the unlocking component, thus creating a pre-tightening force between the end of the elastic pusher away from the mounting seat and the unlocking component. This prevents the unlocking component from being opened due to a small inertial force during a turn, ensuring the safety of the occupants. When a car accident occurs and the car door or side is impacted, the unlocking component rotates or moves due to inertia, causing it to be in the unlocked state. Under the action of the pre-tightening force, the elastic pusher extends out of the sleeve, and the end of the elastic pusher away from the mounting seat abuts against the other side of the unlocking component, thus limiting the unlocking component and preventing it from rotating or moving again. This design is simple and reduces manufacturing costs. Attached Figure Description

[0041] Hidden door handles are a type of door handle designed to blend seamlessly with the car body surface, resulting in a more streamlined and minimalist car appearance.

[0042] With the widespread use of concealed door handles, the resulting safety concerns are increasingly attracting attention from the industry and regulatory authorities, especially in certain special situations where concealed door handles are needed to easily open the car door. For example, after a collision, the concealed handle must be able to unfold promptly to ensure the safety of the occupants. However, existing models or concealed door handle solutions generally rely on an additional backup power supply to the vehicle. After a collision, the backup power supply can provide power to electrically unfold the concealed handle. But in emergency situations such as collisions, or when the backup power supply fails or runs out of power, the concealed door handle is unlikely to open automatically to unlock the door.

[0043] To address the aforementioned issues, this invention provides a collision unlocking mechanism for a concealed door handle, comprising an inertial unlocking component and a limiting blocking component movably disposed within a receiving cavity. When the handle body is in the closed state, the inertial unlocking component is in its initial state, and the blocking end of the limiting blocking component abuts against one side of the inertial unlocking component. Furthermore, when the door is impacted, the inertial unlocking component rotates or moves towards one side of the handle body under inertial force, pushing the handle body relative to the handle recess to switch to the open state. This allows the handle body to unlock the door promptly through the collision unlocking mechanism, ensuring that in case of danger, rescue personnel can promptly open the door from the outside to help the occupants escape, thus improving vehicle safety.

[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0045] like Figures 1-3 As shown, the concealed door handle 1 will be introduced first.

[0046] A concealed door handle 1 is installed on a car door. When people need to get in or out of the car, they can open the door through the concealed door handle 1 and then get out. The concealed door handle 1 includes a handle recess 10 recessed in the car door and a handle body 20 movably disposed within a receiving cavity 100 of the handle recess 10; wherein, the handle body 20 can switch between a closed state and an open state. When the handle body 20 is in the closed state (e.g., Figure 1 As shown), the outer wall of the handle body 20 is flush with the outer surface of the door, so that the hidden door handle 1 does not protrude from the outer surface of the car body when closed, reducing wind resistance, thereby improving the car's range and ensuring the car's aesthetics; and when the handle body 20 is in the open state (as shown), Figure 2 As shown, the handle body 20 is at least partially exposed on the outer surface of the door, so that people can open the door by pulling the handle body 20 when opening the door.

[0047] However, in some designs, the hidden door handles of cars are equipped with an additional backup power supply. After a collision, the backup power supply can ensure that the hidden handles can be opened electrically. However, in the event of an emergency such as a collision or a power outage of the backup power supply, the hidden door handles are difficult to open automatically, making it difficult to rescue occupants trapped in the car due to a collision in a timely manner.

[0048] Therefore, such as Figures 3-6 As shown, this utility model provides a collision unlocking mechanism 30 for a concealed door handle 1. The collision unlocking mechanism 30 includes an inertial unlocking component 31 and a limiting blocking component 32 movably disposed inside the receiving cavity 100. When the handle body 20 is in the closed state, the inertial unlocking component 31 is in the initial state, and the blocking end of the limiting blocking component 32 abuts against one side of the inertial unlocking component 31. When the door is hit, the inertial unlocking component 31 rotates or moves towards one side of the handle body 20 under inertial force, pushing the handle body 20 to switch to the open state relative to the handle recess 10. The inertial unlocking component 31 switches from the initial state to the unlocked state, and the blocking end of the limiting blocking component 32 abuts against the other side of the inertial unlocking component 31 and keeps the inertial unlocking component 31 in the unlocked state.

[0049] Specifically, the working principle of this collision unlocking mechanism 30 is as follows: When a car accident occurs and the door is impacted, the inertial unlocking component 31 is subjected to inertial force, causing it to rotate or translate towards one side of the handle body 20. This, in turn, pushes the handle body 20 relative to the handle recess 10 from a closed state to an open state, so that the handle body 20 is at least partially exposed on the outer surface of the door (e.g., Figure 3 (As shown); At this time, the inertial unlocking component 31 switches from the initial state to the unlocked state. Due to the inertial force, the inertial unlocking component 31 rotates or moves towards one side of the handle body 20. The position of the blocking end of the limiting blocking component 32 on the inertial unlocking component 31 changes from being in contact with one side of the inertial unlocking component 31 when the inertial unlocking component 31 is in the initial state to being in contact with the other side of the inertial unlocking component 31, thereby keeping the inertial unlocking component 31 in the unlocked state (as shown). Figure 4 (As shown); At this time, when the people inside the car are unconscious due to the impact, the rescuers outside the car can open the car door in time through the handle body 20 to carry out the rescue, which is convenient to operate; or, if the people inside the car are not unconscious and can move freely, they can also push the car door open by themselves to quickly escape from the accident scene.

[0050] It should be understood that the car door is equipped with a door cable, which is connected to the handle body 20 via a buckle or bolt. Therefore, when the handle body 20 is in the open position, pulling the door cable by the handle body 20 can keep the door unlocked, making it easier for people inside and outside the car to open the door.

[0051] In summary, the advantages of the collision unlocking mechanism 30 of this concealed door handle 1 are that when the door or the side of the car is hit by a collision, the concealed door handle 1 can unlock the door in time through the collision unlocking mechanism 30, which is conducive to rescuers opening the door from the outside to rescue the people inside the car, or the people inside the car can also push the door open in time to escape from the car while they are conscious, thus ensuring the safety of the people inside the car and improving the safety of the car.

[0052] The structure and operating principle of the inertial unlocking component 31 will be further explained below.

[0053] In one implementation, such as Figure 5 and- Figure 7 As shown, the inertial unlocking assembly 31 includes an unlocking component 310 movably disposed inside the receiving cavity 100, and the limiting and blocking assembly 32 includes a mounting base 321 fixedly disposed inside the unlocking component 310, and a limiting component 320 with one end fixedly mounted on the mounting base 321 and the other end abutting against the unlocking component 310.

[0054] Optionally, in one feasible implementation, when the unlocking component 310 is in its initial state (e.g. Figure 5 As shown), the limiting member 320 has a preload, which ensures that the limiting member 320 exerts a preload on the unlocking member 310. This prevents the unlocking member 310 from entering the unlocked state when the door or side of the car is slightly tapped, thus ensuring the reliability of the unlocking member 310's operation. Furthermore, when the unlocking member 310 is in the unlocked state, the other end of the limiting member 320 abuts against the corresponding side of the unlocking member 310 under the action of the preload, keeping the unlocking member 310 in the unlocked state (as shown). Figure 7 As shown in the figure, the handle body 20 is also kept open, which makes it easy to open the car door and ensures the reliability of the handle body 20.

[0055] Optionally, in another feasible implementation, when the unlocking component 310 is in the initial state, the other end of the limiting component 320 has an adsorption force with one side of the unlocking component 310, which avoids the problem of the door unlocking due to the unlocking component 310 suddenly unlocking when the car is turning, thus ensuring the safety of the occupants; and when the door or the side of the car body is impacted, when the unlocking component 310 switches from the initial state to the unlocked state, the unlocking component 310 pushes the handle body 20 to open it, the other end of the limiting component 320 and the other side of the unlocking component 310 are attracted to each other, and there is an adsorption force between them. At the same time, the handle body 20 is also kept in the open state, which makes it easy to open the car door and ensures the reliability of the handle body 20.

[0056] Specifically, when the unlocking component 310 switches from the initial state to the unlocked state, the adsorption position between the other end of the limiting component 320 and the unlocking component 310 is changed during this process, ensuring the accuracy of the unlocking component 310 when switching from the initial state to the unlocked state.

[0057] The following provides a further explanation of the structure and configuration of the unlocking component 310.

[0058] In one implementation, such as Figures 5-7 As shown, in order to ensure that the unlocking component 310 has sufficient pushing force on the handle body 20, the unlocking component 310 includes a rotating shaft 311 disposed inside the receiving cavity 100 and an inertial block 312 rotatably disposed on the rotating shaft 311; wherein, a pushing part 313 is disposed on the side of the inertial block 312 away from the rotating shaft 311, and the center of mass of the inertial block 312 is located on the outer periphery of the pushing part 313 away from the rotating shaft 311.

[0059] Specifically, when a car accident occurs and the door or side of the car is impacted, the inertial block 312 rotates towards the handle body 20 due to inertial force. At this time, the end of the pushing part 313 pushes the inner wall of the handle body 20, and the handle body 20 is switched to the open state relative to the handle recess 10 (e.g., Figure 6 (as shown); and since the center of mass of the inertial block 312 is located on the outer periphery of the push part 313 away from the rotating shaft 311, when the inertial block 312 is subjected to inertial force, it can quickly rotate around the rotating shaft 311, and push the handle body 20 to switch the handle body 20 to the open state through one end of the push part 313, and then keep the handle body 20 in the open state through the limiting member 320.

[0060] More specifically, the end of the push part 313 used to push the inner wall of the handle body 20 is arc-shaped, so as to avoid damaging the inner wall of the handle body 20 when the end of the push part 313 pushes the inner wall of the handle body 20. Of course, a rubber pad can also be provided on the end of the push part 313 to avoid damage to the inner wall of the handle body 20, but this embodiment does not limit it.

[0061] Alternatively, in one implementation, such as Figures 5-7 As shown, a limiting part 314 is provided at the other end of the inertial block 312; and an arc-shaped transition surface is provided between the pushing part 313 of the inertial block 312 and the limiting part 314. When the handle body 20 is in the open state, the other end of the limiting member 320 engages with the limiting part 314.

[0062] Specifically, when a car accident occurs and the door or side of the car is impacted, the inertial block 312 rotates clockwise around the axis 311 under the influence of inertial force (e.g., Figure 6 As shown, during the process of switching the handle body 20 from the closed state to the open state by pushing one end of the pushing part 313, since there is an arc-shaped transition surface between the pushing part 313 and the limiting part 314 of the inertial block 312, when the other end of the limiting member 320 switches from abutting against the pushing part 313 to abutting against the limiting part 314, the other end of the limiting member 320 can slide along the arc-shaped transition surface, making the operation process relatively smooth and avoiding the problem of the inertial block 312 jamming the other end of the limiting member 320. It should be understood that the other end of the limiting member 320 is the part where the limiting member 320 abuts against the unlocking member 310.

[0063] Optionally, in one embodiment, the rotation angle of the inertial block 312 around the pivot 311 is in the range of 0° to 75°, thereby avoiding the problem that when the side of the car or the door is hit, the rotation angle of the inertial block 312 is too large, causing the inertial block 312 to jam with the handle body 20, resulting in the inertial block 312 being unable to reset.

[0064] In another embodiment, the unlocking component 310 includes a slide rail (not shown in the figure) disposed inside the receiving cavity 100 and a movable block (not shown in the figure) disposed on the slide rail, the movable block being slidably disposed on the slide rail; wherein, a pushing part is provided on the side of the movable block near the handle body 20.

[0065] Specifically, when the car door or the side of the car is impacted, the moving block moves towards one side of the handle body 20 due to inertial force. At this time, the pushing end of the pushing part pushes the inner wall of the handle body 20 and links the handle body 20 to switch from the closed state to the open state relative to the handle recess 10. Furthermore, since the moving block is slidably mounted on the slide rail, it can quickly move along the slide rail under inertial force, thereby pushing the handle body 20 into the open state. It should be understood that a limiting area is also provided on the moving block. When the pushing part of the moving block pushes the handle body 20 into the open state, the other end of the limiting member 320 abuts against the limiting area.

[0066] The following provides a further explanation of the structure and configuration of the limiting component 320.

[0067] Alternatively, in one feasible implementation, such as Figures 5-7 As shown, the limiting component 320 includes a sleeve 322 with one end fixedly mounted on the mounting base 321 and the other end extending toward the unlocking component 310, and an elastic push head 323 disposed in the sleeve 322. The elastic push head 323 can switch between a compressed state and an extended state relative to the sleeve 322.

[0068] Specifically, when the unlocking component 310 is in its initial state, the elastic push head 323 is compressed relative to the sleeve 322 and has a preload. The end of the elastic push head 323 away from the mounting base 321 abuts against the side of the unlocking component 310, thereby creating a preload between the end of the elastic push head 323 away from the mounting base 321 and the unlocking component 310. This prevents the unlocking component 310 from being subjected to a small inertial force during vehicle turning, thus avoiding the handle body 20 from unexpectedly opening during driving. Regarding the issue of the open state, the safety of the occupants inside the vehicle is ensured; when a car accident occurs and the car door or side is impacted, the unlocking component 310 rotates or moves due to inertial force, so that when the unlocking component 310 is in the unlocked state, the elastic push head 323 extends out of the sleeve 322 under the action of pre-tightening force, and the end of the elastic push head 323 away from the mounting base 321 abuts against the other side of the unlocking component 310, thereby limiting the unlocking component 310 so that the unlocking component 310 will not rotate or move again, and the structure is simple, reducing manufacturing costs.

[0069] More specifically, the structure and configuration of the flexible pusher 323 are not limited.

[0070] In one embodiment, the elastic push head 323 includes a spring and a push rod, wherein the push rod is adapted to and slidably connected to the sleeve 322, one end of the spring is fixedly connected to the bottom wall surface of the sleeve 322, and the other end is fixedly connected to one end of the push rod, and the other end of the push rod abuts against the unlocking component 310. It should be understood that the sliding connection method can be a slide rail and slider cooperation, a slide groove and ball cooperation, etc., and this embodiment is not limited thereto.

[0071] Alternatively, in another feasible implementation, such as Figure 8 and Figure 9 As shown, the limiting component 320 includes an elastic reset component 324 disposed inside the receiving cavity 100. One end of the elastic reset component 324 is fixedly connected to the mounting base 321, and the other end is connected to the corresponding side of the unlocking component 310.

[0072] Specifically, when the unlocking component 310 is in its initial state, the elastic reset component 324 is in a compressed state and has a pre-tightening force. One side of the elastic reset component 324 abuts against one side of the unlocking component 310, avoiding the risk of the handle body 20 suddenly opening during a car turn. When a car accident occurs and the car door or side is impacted, the unlocking component 310 rotates or moves due to inertial force, causing the unlocking component 310 to be in the unlocked state. Under the action of the pre-tightening force, the elastic reset component 324 can be quickly released and is in the released state, so that the other side of the elastic reset component 324 can quickly abut against the other side of the unlocking component 310, which has the advantage of fast response speed.

[0073] Specifically, the structure and arrangement of the elastic reset element 324 are not limited.

[0074] In one embodiment, when the unlocking component 310 is configured to include an inertial block 312, the elastic reset component 324 can be configured as a torsion spring sleeved on the rotating shaft 311. One end of the torsion spring is fastened to the mounting base 321 by a pin or rivet and pressed into the energy storage position by the inertial block 312. When the inertial block 312 rotates under inertial force, the torsion spring unfolds and presses against the inertial block 312, ensuring that the inertial block 312 is in the unlocked state, so that the handle body 20 is in the open state.

[0075] Alternatively, in another feasible implementation, the limiting blocking assembly 32 includes a first magnetic attraction component (not shown in the figure) disposed on one side of the unlocking component 310, a second magnetic attraction component (not shown in the figure) disposed on the other side of the unlocking component 310, and a third magnetic attraction component (not shown in the figure) disposed on the mounting base 321.

[0076] When the unlocking component 310 is in its initial state, the first magnetic component and the third magnetic component are attracted to each other, avoiding the risk that the handle body 20 will suddenly open due to inertial force during the car's turning process, thus ensuring the car's safety performance. When the car is involved in an accident and the car door or side is impacted, the unlocking component 310 rotates or moves due to inertial force, causing the unlocking component 310 to be in the unlocked state. At this time, the second magnetic component and the third magnetic component are attracted to each other, keeping the handle body 20 in the open state. Furthermore, by having the first magnetic component attract the second and third magnetic components respectively, the unlocking component 310 has the advantage of high switching accuracy when switching from the initial state to the unlocked state.

[0077] More specifically, the structure and arrangement of the first, second, and third magnetic components are not limited; for example, they can be magnetic blocks, magnetic sheets, magnetic rods, etc. It is important to understand that the first and second magnetic components have the same magnetism, the third magnetic component has the opposite magnetism to the first magnetic component, and the third magnetic component also has the opposite magnetism to the second magnetic component.

[0078] This utility model also provides a hidden door handle 1, including the aforementioned collision unlocking mechanism 30. When the car door or the side of the car is hit, the hidden door handle 1 can unlock the car door in time through the collision unlocking mechanism 30, which is conducive to rescuers opening the car door from the outside to rescue the people inside the car, or the people inside the car can also push the car door open in time to escape from the car while they are conscious, thus ensuring the safety of the people inside the car and improving the safety of the car.

[0079] Optionally, in one embodiment, the handle body 20 is rotatably disposed within the receiving cavity 100 of the handle recess 10. When the handle body 20 is switched from the initial state to the open state, the handle body 20 is opened by rotation.

[0080] Alternatively, in another embodiment, the handle body 20 is translatably disposed within the receiving cavity 100 of the handle recess 10, and when the handle body 20 switches from the initial state to the open state, the handle body 20 is opened by rotating and translating.

[0081] Regarding the method and specific structure of the handle body 20 switching between the initial state and the open state, this utility model does not impose a unique limitation on this, and those skilled in the art can design it according to the actual situation and specific needs.
