Description

Technical Field

[0001] The present invention relates to the technical field of vehicle door handles, in particular to a vehicle door handle safety device based on a supercapacitor. Background Art

[0002] With the development of society and the progress of the times, cars have become an increasingly common means of transportation for many people, and people's requirements for the appearance and functionality of car components are also becoming increasingly higher. Among them, car door handles are an important part of the car door system. They are installed on the car door and are used to unlock and open the car door. In the prior art, car door handles generally come in two forms. One is the common traditional exposed door handle. However, the protruding door handle not only affects the aesthetics of the entire vehicle appearance, but also causes a certain amount of wind resistance, thereby increasing the vehicle's driving resistance. To reduce wind resistance and improve the aesthetics of the entire vehicle appearance, more and more models are beginning to adopt another form: hidden handles. With the development of intelligent vehicles, the hidden handles used in some models are increasingly dependent on the vehicle's power control system. However, most vehicles do not have a reliable backup power supply such as supercapacitors, which makes the actual use of cars with hidden handles less safe.

[0003] The switch of the hidden door handle in the prior art is highly dependent on electric control, so once the car collides and the battery is damaged or the line is short-circuited, the entire electric unlocking system will be paralyzed, and it will be difficult to open the door in time whether inside or outside the car, which will seriously affect the timely escape of the people inside the car. In addition, the switch control structure of the door lock as a whole lacks redundant design. Once the door lock is structurally damaged after a collision, it will affect the normal opening of the door, which will greatly reduce the safety of the door in an accident and is not conducive to people's actual application. Therefore, those skilled in the art provide a car door handle safety device based on a supercapacitor to solve the problems raised in the above background technology. Summary of the Invention

[0004] The purpose of the present invention is to provide a car door handle safety device based on a supercapacitor to solve the safety hazard that hidden door handles cannot unlock and open the car door when the power is cut off due to failure of the electric system or collision, thereby endangering the timely escape of people in the car.

[0012] As a further description of the above technical solution: the adjusting part includes an adjusting screw rotatably connected to the vehicle door frame, two groups of adjusting blocks that can be displaced in opposite directions are threadedly connected to the adjusting screw, an auxiliary rod sliding through the two groups of adjusting blocks is fixedly installed in the vehicle door frame, and an arc frame slidably connected to the outside of the adjusting block is fixedly installed on the top of the push plate.

[0013] As a further description of the above technical solution: the toggle arm includes a second support column fixedly installed in the vehicle door frame, and two groups of toggle plates are rotatably installed on the second support column. A push rod is fixedly installed between the bottom ends of the two groups of toggle plates and abuts the inner side of the toggle groove on the swing plate. The tops of the two groups of toggle plates are provided with a card slot for the elastic part to slide, and a limit lever is fixedly installed inside the vehicle door frame and abuts the outer side of the toggle plate.

[0014] As a further description of the above technical solution: the elastic member includes two groups of wheels rotatably mounted on the second support column, a round rod is fixedly mounted between the two groups of wheels and abuts the inner walls of the slots on the two groups of swing plates, the middle part of the round rod is connected to the movable plate through a rotatably mounted movable rod, two groups of sliding rods slidably connected to the door frame are fixedly mounted on one side of the movable plate, and a second spring is fixedly mounted between the movable plate and the door frame and is sleeved on the outside of the sliding rod.

[0015] As a further description of the above technical solution: the first control member includes a cross bar fixedly installed between two groups of toggle plates, the cross bar is connected to a sliding shell through two groups of first connecting rods installed in rotation, a vertical rod slidingly extending into the sliding shell is fixedly installed inside the door frame, a third spring mounted on the outer ring of the vertical rod is fixedly installed between the sliding shell and the door frame, the sliding shell is connected to a transmission block whose end abuts the door handle through two groups of second connecting rods installed in rotation, and the transmission block is slidably connected to the door frame.

[0016] As a further description of the above technical solution: the second control component includes a drive motor fixedly installed in the vehicle door frame through a frame plate, the output end of the drive motor is fixedly connected to a worm, and one side of one group of the toggle plates is fixedly installed with a worm wheel meshing with the worm.

[0017] As a further description of the above technical solution: a supercapacitor assembly is fixedly installed inside the door frame, and the supercapacitor assembly connected in parallel with the main power supply of the car is electrically connected to the input end of the drive motor.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention introduces a triple-redundant "mechanical-electrical-emergency" linkage mechanism into the concealed door handle and, for the first time, utilizes a distributed supercapacitor assembly in the vehicle door as an independent backup power source, significantly improving unlocking reliability in collision-induced power outage scenarios. Conventional solutions rely on a single motor or mechanical pull rod, which fail if the power is interrupted or the connecting rod deforms. The present invention, by utilizing a parallel drive path consisting of a dual toggle arm and a swing arm, enables the door lock to be independently triggered by pulling the door handle from the outside, using an electric button, or by rotating the knob inside the vehicle. A third emergency path, directly connected via an extrusion, pull rod, and actuator, allows for direct unlocking by manually rotating the knob even if the toggle arm is stuck in an impact. Furthermore, the supercapacitor assembly is connected in parallel with the main power source, enabling a high current to drive the motor to open the door once the vehicle loses power. It is also rated for 500,000 cycles, is fire-proof in extreme environments, and does not increase the wiring and space burden of the vehicle. This device achieves the dual safeguards of "power-off door unlocking" and "mechanical door jamming prevention," resolving the industry pain point of concealed door handles hindering escape due to electronic control failure. It balances everyday convenience with safety in extreme operating conditions, offering significant practical value. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figures 1 to 8 In an embodiment of the present invention, a supercapacitor-based automobile door handle safety device includes a door frame 10, a swing arm 20, and a toggle arm 40. A hidden door handle 11 is rotatably mounted on the outer side of the door frame 10. The swing arm 20 rotatably mounted in the door frame 10 is provided with a pull rod 12 that can swing with its rotation, and an extrusion member 30 is provided in the swing arm 20 that can push the pull rod 12 to slide up and down in the swing arm 20. The pull rod 12 swings with the swing arm 20 or moves up and down relative to the swing arm 20. The sliding movement can drive the actuator 13 connected to its bottom end to move. Two sets of symmetrical toggle arms 40 are installed for rotation inside the door frame 10. Both sets of toggle arms 40 are connected with elastic parts 50 to assist in their automatic reset. One set of toggle arms 40 is connected with a first control part 60 that rotates by following the pulling of the door handle 11, and the other set of toggle arms 40 is connected with a second control part 70 that electrically controls its rotation. The rotation of any set of toggle arms 40 can drive the rocking arm 20 to rotate away from the other set of toggle arms 40.

[0035] When the automobile handle switch device is actually used, the first control component 60 is connected to the mechanical pull handle on the outside of the vehicle door, and the hidden door handle 11 is rotatably connected to the door frame 10. During actual operation, the user can press one end of the door handle 11 to lift the other end, so that the user can hold the door handle 11 to open the door. The second control component 70 is connected to the vehicle body power supply, and an electric control button that can operate the second control component 70 is set on the inside of the vehicle door, which can effectively improve the convenience of daily use of the car. The mechanical control end of the extrusion component 30 extends to the interior of the vehicle body. The user can manually rotate the extrusion component 30 when the vehicle body has an accident or failure. The extrusion component 30 can directly drive the actuator 13 to move through the pull rod 12. The actuator 13 is used to connect to the vehicle body door lock.

[0036] When the door handle 11 drives the first control part 60 to operate, the first control part 60 can drive the toggle arm 40 connected thereto to rotate, and the rotation of the toggle arm 40 can drive the swing arm 20 to rotate in one direction, and the swing arm 20 drives the pull rod 12 to swing to one side together, which can pull the actuator 13 to move. The actuator 13 is used to link the operation of other components of the vehicle body door lock. When the electronic control system controls the second control part 70 to operate, the second control part 70 can drive the toggle arm 40 connected thereto to rotate, and the rotation of the toggle arm 40 can drive the swing arm 20 to rotate in the other direction, and the swing arm 20 drives the pull rod 12 to swing to the other side together, which can pull the actuator 13 to move. The extrusion part 30 disengages from the toggle arm 40 and can directly control the pull rod 12 on the swing arm 20 to drive the actuator 13 to move, which can open the vehicle door in an emergency when the toggle arm 40 and other components are damaged by an accident, further improving the safety of the vehicle body door lock during actual use.

[0037] In one embodiment, see Figures 1 to 6 Specifically, the rocking arm 20 includes a first support column 201 fixedly installed in the door frame 10, and two groups of swing plates 202 are rotatably installed on the first support column 201. Both sides of the two groups of swing plates 202 are provided with a toggle groove 14 adapted to the toggle arm 40. Furthermore, the rocking arm 20 also includes a group of frame rods 203 and two groups of reinforcing rods 204 fixedly installed between the two groups of swing plates 202. Two groups of baffles 205 are fixedly installed on the frame rods 203 rotatably connected to the first support column 201, and the pull rod 12 is slidably installed between the two groups of baffles 205.

[0038] The rotating toggle arm 40 component can drive the two groups of swing plates 202 to rotate through the toggle slot 14. The reinforcing rod 204 installed between the two groups of swing plates 202 can improve the overall support strength of the swing arm 20. The two groups of rotating swing plates 202 can drive the frame rod 203 to rotate outside the first support column 201. The rotational connection between the components can be connected through bearings to improve the smoothness. The two groups of baffles 205 can provide support and limit for the extrusion part 30 while also providing activity space and limit for the pull rod 12. The outside of the frame rod 203 can be provided with an anti-slip strip to limit the relative rotation between the extrusion part 30 and the frame rod 203, so that when the frame rod 203 rotates, it drives the extrusion part 30 and the pull rod 12 to swing together.

[0039] In detail, the extrusion member 30 includes two groups of push plates 301 slidably mounted on the frame rod 203, a first spring 302 is installed between the push plate 301 and the baffle 205, and a connecting rod 303 is hinged between the bottom end of the push plate 301 and the pull rod 12 on both sides, and the top of the push plate 301 is connected to an adjustment member 304 for controlling its displacement, wherein the adjustment member 304 includes an adjustment screw 3041 rotatably connected to the door frame 10, and two groups of reversibly displaceable adjustment blocks 3042 are threadedly connected to the adjustment screw 3041, an auxiliary rod 3044 is fixedly installed in the door frame 10 to slide through the two groups of adjustment blocks 3042, and an arc frame 3043 is fixedly installed on the top of the push plate 301 to slide with the outside of the adjustment block 3042.

[0040] The end of the adjusting screw 3041 can be provided with a knob extending to the inside of the vehicle body. The operator rotates it to drive the adjusting screw 3041 to rotate. The adjusting screw 3041 is provided with two sets of symmetrical and opposite thread grooves. The rotation of the adjusting screw 3041 can drive the two sets of symmetrical adjusting blocks 3042 connected to its external thread to move in opposite directions. The adjusting blocks 3042 can slide linearly up and down the auxiliary rod 3044. The adjusting blocks 3042 can drive the push plates 301 to slide on the outside of the frame rod 203 through the arc frame 3043. The bottom ends of the two sets of push plates 301 can drive the pull rod 12 to slide between the two sets of baffles 205 through the connecting rod 303, so that the sliding baffle 205 drives the actuator 13 to move, and the arc frame 3043 can be rotated and adjusted on the outside of the adjusting block 3042. The further provided first spring 302 can be extended and retracted following the use of the push plate 301. The first spring 302 can facilitate the displacement of the auxiliary pull rod 12 and subsequent reset.

[0041] Based on the above embodiments, see Figures 1 to 8 Specifically, the toggle arm 40 includes a second support column 401 fixedly installed in the door frame 10, and two groups of toggle plates 402 are rotatably installed on the second support column 401. A push rod 403 is fixedly installed between the bottom ends of the two groups of toggle plates 402 to abut against the inner side of the toggle groove 14 on the swing plate 202. The tops of the two groups of toggle plates 402 are provided with a card slot 15 for the elastic member 50 to slide. A limit lever 404 is fixedly installed inside the door frame 10 to abut against the outer side of the toggle plate 402.

[0042] The control member drives the toggle plate 402 connected to it to rotate outside the second support column 401. The bottoms of the two sets of toggle plates 402 are connected by a push rod 403. The end of the push rod 403 abuts the inner side of the toggle groove 14, so that when the toggle plate 402 drives the push rod 403 to rotate, the push rod 403 moves in the toggle groove 14 to drive the swing plate 202 to rotate. The set limit lever 404 can limit the rotation range of the toggle plate 402. The elastic member 50 further provided can assist in the movement and limitation of components such as the toggle arm 40.

[0043] Correspondingly, the elastic member 50 includes two groups of rotating wheels 501 rotatably mounted on the second support column 401, a round rod 502 is fixedly mounted between the two groups of rotating wheels 501 and abuts against the inner walls of the slots 15 on the two groups of swing plates 202, the middle part of the round rod 502 is connected to the movable plate 503 through a rotatably mounted movable rod 506, two groups of sliding rods 504 slidably connected to the door frame 10 are fixedly mounted on one side of the movable plate 503, and a second spring 505 is fixedly mounted between the movable plate 503 and the door frame 10 and is sleeved on the outside of the sliding rod 504.

[0044] When the toggle plate 402 rotates, it can push the round rod 502 to rotate, and the round rod 502 can drive the two sets of wheels 501 to rotate. The rotating round rod 502 can pull the movable plate 503 to move through the movable rod 506, and the movable plate 503 can drive the sliding rod 504 to slide in the door frame 10. While moving, the movable plate 503 can drive the second spring 505 to expand and contract. The resetting of the second spring 505 can help to position the toggle plate 402 to the initial position where it abuts the limit lever 404, which is beneficial to improving the stability of the overall use of the car door handle safety device.

[0045] The preferred embodiments of the control element of the present invention are described in detail below. However, in addition to these detailed descriptions, the present invention may also have other embodiments.

[0046] In detail, the first control member 60 includes a cross bar 601 fixedly installed between the two groups of toggle plates 402, the cross bar 601 is connected to the sliding housing 602 through two groups of first connecting rods 606 that are rotatably installed, a vertical rod 603 that slides and extends into the sliding housing 602 is fixedly installed inside the door frame 10, a third spring 604 that is sleeved on the outer ring of the vertical rod 603 is fixedly installed between the sliding housing 602 and the door frame 10, the sliding housing 602 is connected to a transmission block 605 whose end abuts the door handle 11 through two groups of second connecting rods 607 that are rotatably installed, and the transmission block 605 is slidably connected to the door frame 10.

[0047] Pulling the door handle 11 can push the transmission block 605 to slide in the door frame 10. The transmission block 605 can drive the sliding shell 602 to slide up and down on the outer circle of the vertical rod 603 through the second connecting rod 607. The moving sliding shell 602 can drive the third spring 604 to extend and retract. At the same time, the sliding shell 602 can pull the cross bar 601 to move through the first connecting rod 606. The cross bar 601 can drive the toggle plate 402 connected to it to rotate. The set third spring 604 is convenient for assisting the door handle 11 to reset and the automatic reset of a group of toggle arms 40. The mechanical control component has a simple structure and strong stability.

[0048] In detail, the second control component 70 includes a drive motor 701 fixedly installed in the door frame 10 through the frame plate 17, and the output end of the drive motor 701 is fixedly connected to the worm 702, and one side of a group of toggle plates 402 is fixedly installed with a worm wheel 703 engaged with the worm 702. When the drive motor 701 is started, the drive motor 701 drives the worm 702 and the worm wheel 703 to rotate, and the worm wheel 703 can drive the toggle plate 402 connected thereto to rotate.

[0049] A backup power supply supercapacitor assembly 16 for controlling the operation of the drive motor 701 can be set inside the door frame 10. The supercapacitor assembly 16 is fixedly installed inside the door frame 10. The supercapacitor assembly 16 connected in parallel with the main power supply of the vehicle is electrically connected to the input end of the drive motor 701. The positive pole of the supercapacitor assembly 16 is connected to the positive pole of the main power supply of the vehicle, and the negative pole is connected to the negative pole of the main power supply to form a parallel circuit to increase the total capacitance value and energy storage capacity of the system. Wires are led out from the positive and negative poles of the supercapacitor assembly 16 after parallel connection and connected to the power input end of the drive motor 701 (need to match the rated voltage and current of the motor) to provide power for the motor. A fuse or circuit breaker can be connected in series in the connection line to prevent overcurrent from damaging the components. If the voltage needs to be adjusted, a DC-DC converter can be added.

[0050] Distributed supercapacitor assemblies 16 can be assembled in all four car doors, that is, a group of small supercapacitor modules (such as 5V, 10F, or matched according to the power supply of the specific car door) are installed at the four car door positions. This is equivalent to adding a group of highly reliable backup power supplies at the car door positions. By connecting them in parallel and on the car door control circuit, once the main power supply of the car fails, the backup power supply of the supercapacitor assembly 16 can be used to open the car door in time, thereby ensuring personal safety.

[0051] Advantages of supercapacitor assembly 16: Taking advantage of the safety, reliability, long life and high current discharge of supercapacitors, especially the fact that they will not catch fire or explode under extreme conditions, they can meet environmental conditions such as double 85. At the same time, they have a cycle performance of more than 500,000 times, and will not fail under long-term power supply. They can output high current at critical moments, etc., to achieve a parallel structure with new energy vehicle lithium batteries as large energy storage pools and supercapacitor small modules as small energy storage pools, to achieve a highly reliable power supply solution and solve the current safety hazard problem of hidden door handles.
