Description

Technical Field

[0001] This invention belongs to the field of automotive safety technology, specifically relating to an electronic unlocking device inside a car door with a mechanical emergency unlocking function. Background Technology

[0002] Cars are common means of transportation. As people's living standards improve, the popularity of cars is increasing. Most traditional cars are fuel-powered vehicles. These cars have door handles (mechanical unlocking wrenches) on the inside of the door panels. By turning the door handle, the door can be unlocked and opened.

[0003] With advancements in technology, electric vehicles powered by lithium batteries have emerged on the market. Compared to traditional gasoline-powered vehicles, electric vehicles operate with lower noise, emit no exhaust fumes, offer better ride comfort, and are more environmentally friendly, gradually becoming the mainstream. To clearly distinguish them from traditional gasoline-powered vehicles, the inner door panels of electric vehicles mostly feature only electronic buttons or other electronic unlocking devices. Triggering these buttons sends an electrical signal to the motor, unlocking the door. The less frequently used emergency mechanical unlocking wrench is placed in a concealed location or concealed through a design that minimizes its visibility, resulting in a clean and minimalist aesthetic for the inner door panels. To enhance the sense of technology and sophistication, some electric vehicles even make the emergency mechanical unlocking cable into a pull ring, hidden behind a removable cover. To use it, the cover needs to be removed, and then a finger is used to pull the ring to unlock it. In emergency situations such as power outages due to collisions or unexpected power outages, it is easy for occupants to not be able to find the emergency mechanical unlocking mechanism immediately, and the electronic button is in a malfunctioning state, making it impossible to unlock the door. This can lead to dangerous situations where occupants are trapped inside the vehicle. At the same time, when occupants find that pressing the electronic button has no effect, they may subconsciously press the electronic button frequently and forcefully in the hope of unlocking the door. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an electronic unlocking device for the interior of a car door with a mechanical emergency unlocking function.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is an electronic unlocking device inside a car door with a mechanical emergency unlocking function, comprising:

[0006] A panel connected to the inner door panel of the vehicle door, the panel having a through hole;

[0007] A housing connected to the bottom surface of the panel, the housing and the panel forming a receiving cavity;

[0008] An electronic button is provided in the receiving cavity, and the top of the electronic button is provided with a pressable keycap, which extends into the through hole;

[0009] The bottom of the electronic button is connected to an eccentric bracket, which is connected to the cable for unlocking the car door. The eccentric bracket is movably supported on the housing. The supporting force of the eccentric bracket on the electronic button is greater than the first pressing force on the button cap when the car door is unlocked under normal circumstances, but less than the second pressing force on the button cap when the car door is unlocked under emergency circumstances.

[0010] Preferably, the eccentric bracket is rotatably supported on the outer casing.

[0011] More preferably, the upper end of the eccentric bracket is provided with a casing, the casing is fitted onto the electronic button, and the outer wall of the casing is provided with a pivot, the pivot being rotatably inserted into a pivot hole on the outer casing.

[0015] More preferably, the torque formed by the elastic force of the elastic element on the rotating shaft is greater than the torque formed by the first pressing force on the rotating shaft and less than the torque formed by the second pressing force on the rotating shaft.

[0016] More preferably, the elastic element includes a spring sheet, a compression spring, or a torsion spring.

[0017] More preferably, when the elastic element is a spring sheet, the upper end of the spring sheet is inserted into a slot in the inner wall of the outer casing, and the lower end of the spring sheet is bent and pressed against the side wall of the casing. The contact line between the spring sheet and the casing is lower than the pivot.

[0018] More preferably, the bottom of the housing is connected to a cable end block for threading the cable, and the lower end of the eccentric bracket passes through the opening at the bottom of the housing and is connected to the end of the cable on the cable end block.

[0019] More preferably, the cable end block is provided with an arc-shaped groove, the center of which falls on the axis of the rotating shaft, and a slidable pin is provided in the arc-shaped groove, the pin being perpendicularly connected to the end of the cable.

[0020] More preferably, the lower end of the eccentric bracket is provided with a hook portion with a lateral opening. The hook portion hooks the pin. When the eccentric bracket rotates relative to the outer shell, the hook portion drives the pin to slide along the arc-shaped groove and pulls the cable.

[0021] More preferably, there are two arc-shaped grooves spaced apart, and the two ends of the pin are slidably mounted on the two arc-shaped grooves. The hooking part extends between the two arc-shaped grooves and hooks the middle of the pin.

[0022] Preferably, the second pressing force is at least twice the first pressing force.

[0024] Preferably, when the keycap is subjected to the first pressing force, the keycap moves downward within the through hole, and when the keycap is subjected to the second pressing force, the keycap moves downward and disengages from the through hole.

[0025] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0026] The present invention provides an electronic unlocking device for the interior of a car door with a mechanical emergency unlocking function. It includes a housing with a panel having a through hole, a shell connected to the bottom surface of the panel forming a cavity with the panel, and an electronic button located within the cavity. A keycap on the top of the electronic button extends into the through hole. An eccentric bracket connected to a cable at the bottom of the electronic button movably supports the outer shell. The supporting force of the eccentric bracket on the electronic button is greater than the first pressing force on the keycap during normal door unlocking, but less than the second pressing force during emergency door unlocking. When a passenger normally unlocks the door, the eccentric bracket supports the electronic button, enabling electronic unlocking. When a passenger unconsciously presses the keycap forcefully due to electronic unlocking failure, the electronic button moves relative to the outer shell along with the eccentric bracket, functioning as a traditional fuel-powered car door wrench, pulling the cable to achieve emergency door unlocking. This device has a mechanical emergency unlocking function. Attached Figure Description

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more readily understood by those skilled in the art.

[0033] like Figures 1 to 4 As shown, the electronic unlocking device inside a car door with a mechanical emergency unlocking function provided by the present invention includes: a panel 10, a housing 20, an electronic button 30, and an eccentric bracket 40. The panel 10 is connected to the inner door panel of the car door and has a through hole 11. The housing 20 is connected to the bottom surface of the panel 10, and the housing 20 and the panel 10 form a receiving cavity 21. The electronic button 30 is disposed in the receiving cavity 21, and the top of the electronic button 30 has a pressable keycap 31 that extends into the through hole 11. The eccentric bracket 40 is connected to the bottom of the electronic button 30 and is connected to the door unlocking cable 50. The eccentric bracket 40 is movably supported on the housing 20. The supporting force of the eccentric bracket 40 on the electronic button 30 is greater than the first pressing force on the keycap 31 when the door is unlocked under normal circumstances, and less than the second pressing force on the keycap 31 when the door is unlocked under emergency circumstances.

[0034] The advantage of this design is that when the occupants unlock the car door normally (under normal circumstances), the eccentric bracket can support the electronic button to achieve electronic unlocking of the door. When the occupants subconsciously press the button hard due to the failure of electronic unlocking (in an emergency), the electronic button moves relative to the outer shell with the eccentric bracket, acting as a traditional fuel vehicle door wrench, pulling the cable to achieve emergency unlocking of the door, thus having a mechanical emergency unlocking function.

[0035] In this embodiment, the eccentric bracket 40 is rotatably supported on the outer shell 20. Specifically, the upper end of the eccentric bracket 40 is provided with a casing 41, which is fitted onto the electronic button 30. The casing 41 is lower than the keycap 31. The outer wall of the casing 41 is provided with a pivot 411, which is rotatably inserted into the pivot hole 22 on the outer shell 20, so that the eccentric bracket 40 is rotatably supported on the outer shell 20.

[0036] To facilitate pulling the cable 50, the extension direction of the pivot 411 is perpendicular to the pressing direction of the keycap 31. Specifically, the electronic button 30 is rectangular, the pivot 411 extends along the width of the electronic button 30, the housing 41 is a rectangular shell with an open top, and the pivot 411 is parallel to a pair of sidewalls along the length of the housing 41 and is positioned close to one of the sidewalls to achieve eccentric rotation of the eccentric bracket 40 relative to the housing 20.

[0037] To facilitate resetting, an elastic element 23 is further connected to the inner wall of the outer shell 20. The free end of the elastic element 23 abuts against the casing 41. The elastic element 23 has the tendency to resist the rotation of the eccentric bracket 40 and reset the eccentric bracket 40. Specifically, the torque formed by the elastic force of the elastic element 23 on the rotating shaft 411 is greater than the torque formed by the first pressing force on the rotating shaft 411 and less than the torque formed by the second pressing force on the rotating shaft 411. The elastic element 23 is preferably a spring, compression spring, or torsion spring. In this embodiment, for ease of installation, the elastic element 23 is a spring. The upper end of the spring is inserted into the slot 24 in the inner wall of the outer shell 20, and the lower end of the spring is bent and abuts against the side wall of the casing 41. The contact line between the spring and the casing 41 is lower than the rotating shaft 411.

[0038] To facilitate the connection of the cable 50, in this embodiment, a cable end block 51 for threading the cable 50 is detachably inserted into the bottom of the outer casing 20. The lower end of the eccentric bracket 40 passes through the opening 25 at the bottom of the outer casing 20 and connects to the end of the cable 50 on the cable end block 51. Specifically, the cable end block 51 is provided with an arc-shaped groove 511, the center of which falls on the axis of the rotating shaft 411. A slidable pin 512 is provided in the arc-shaped groove 511, and the pin 512 is perpendicularly connected to the end of the cable 50. Furthermore, the lower end of the eccentric bracket 40 is provided with a hook portion 42 with a lateral opening. The hook portion 42 hooks the pin 512. When the eccentric bracket 40 rotates relative to the outer casing 20, the hook portion 42 drives the pin 512 to slide along the arc-shaped groove 511, pulling the cable 50 to realize the emergency unlocking of the door.

[0039] To improve the stability of the hooking part 42 hooking the pin 512, the arc-shaped slide groove 511 is further provided in two parallel sections. The two ends of the pin 512 are slidably mounted on the two arc-shaped slide grooves 511, and the hooking part 42 extends between the two arc-shaped slide grooves 511 and hooks the middle of the pin 512.

[0040] In this embodiment, the second pressing force is at least twice the first pressing force; the electronic button 30 includes a micro switch and a touch switch; when the keycap 31 is subjected to the first pressing force, the keycap 31 moves downward in the through hole 11; when the keycap 31 is subjected to the second pressing force, the keycap 31 moves downward and disengages from the through hole, so that the eccentric bracket 40 sinks and rotates.

[0041] To further enhance aesthetics, when the keycap 31 is not pressed, the upper surface of the keycap 31 is flush with the plane containing the upper edge of the through hole 11.

[0042] It should be noted that the cable 50 needs to be used in conjunction with the cable sheath 52, with the end of the cable sheath 52 abutting against the cable end block 51.

[0043] This invention combines mechanical and electronic unlocking, retaining the premium feel of electronic unlocking during normal use, while also enabling mechanical unlocking in emergency situations by using electronic buttons and eccentric brackets to function as door handles in fuel-powered vehicles. This eliminates the need for additional locations to install mechanical unlocking mechanisms, and is convenient and reliable. After emergency unlocking, the eccentric bracket can be driven to rotate in the opposite direction via a spring, achieving automatic reset.

[0044] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
