Description

Technical Field

[0001] This utility model relates to the field of automotive parts, specifically to an electromechanical dual unlocking structure. Background Technology

[0002] Currently, for some new energy vehicles and electric vehicles, the door unlocking method is usually an electromechanical dual unlocking method. The electromechanical dual unlocking method is achieved through an electromechanical dual unlocking structure, which includes a handle, handle base, micro switch, cable, and first and second springs located on the inside of the door. The handle is rotatably connected to the handle base, and the handle has a rotating part. The probe of the micro switch contacts the rotating part. The micro switch is electrically connected to the electronic lock part of the door lock, and the cable is connected to the mechanical lock part of the door lock.

[0003] During unlocking, pulling the handle causes it to rotate on its base, driving the rotating part to rotate as well. A sensor detects this movement, and a microswitch detects the handle's rotation, transmitting a signal. The electronic lock receives this signal and automatically unlocks, thus electrically unlocking the door. If electronic unlocking fails, the handle can be pulled further (from the angle used for electronic unlocking). This pulls a cable, which in turn pulls the mechanical lock, unlocking the door mechanically and preventing it from opening when electronic unlocking fails.

[0004] The function of the first spring mentioned above is to reset the handle after it is rotated. In this way, when the door is unlocked electronically, after the handle is released, the handle can be rotated in the opposite direction and reset under the action of the first spring.

[0005] The function of the second-stage spring is to provide passengers with a clear tactile feedback for both electronic and mechanical unlocking methods when turning the handle. During electronic unlocking, the handle rotates at a small angle, and the second-stage spring does not engage, making the handle easier and less strenuous to turn. If the handle is turned beyond the angle permitted for electronic unlocking, the second-stage spring engages, and the passenger will feel more noticeable resistance. The passenger can then determine from this tactile feedback that the handle has reached the correct position for electronic unlocking and does not need to continue turning, thus avoiding over-turning.

[0006] However, currently the first and second springs are usually coaxially connected, and the spindle of a handle needs to pass through two springs. This places high demands on the spatial arrangement of the two springs. At the same time, with the spring force, it is difficult to rotate the handle onto the handle seat, resulting in slow assembly efficiency. Utility Model Content

[0007] The present invention aims to provide an electromechanical dual unlocking structure to achieve the first spring and the second spring being set on different axes, which facilitates the assembly of the electromechanical dual unlocking structure and reduces the assembly difficulty.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an electromechanical dual unlocking structure, including a handle base, a handle rotatably mounted on the handle base, a micro switch, and a first-position spring for resetting the handle. The handle is provided with a rotating part, and the probe of the micro switch contacts the rotating part. It also includes a swing pawl rotatably mounted on the handle base and a second-position spring that provides rotational resistance to the swing pawl. The end of the swing pawl is an abutting end, which is opposite to the tail end of the handle.

[0009] When the handle rotates within the range of electronic unlocking, the tail end and the abutting end of the handle are separated; when the handle rotates within the range of mechanical unlocking, the tail end and the abutting end of the handle are in abutting state.

[0010] The principle and advantages of this solution are as follows: When it is necessary to unlock the car door lock, pull the handle. The handle rotates on the handle seat. The handle first rotates within the rotation range of the electronic unlocking mechanism. The handle drives the rotating part to rotate together. The rotating part slides relative to the probe. The micro switch detects the rotation of the handle. The electronic lock part of the car door lock receives the rotation signal of the handle and unlocks automatically, allowing the car door to open. During this process, the tail end of the handle does not abut against the abutting end of the swing pawl, making the rotation of the handle relatively effortless and easy.

[0011] As the handle continues to rotate, its tail end will abut against the abutting end. The pawl, under the action of the second-position spring, provides resistance to the handle's rotation. At this point, the resistance is relatively large, and once the passenger feels a noticeable resistance, they will stop pulling the handle and release it. The handle will then rotate in the opposite direction to reset under the action of the first-position spring. Since the passenger does not continue to pull the handle, it will not mechanically unlock.

[0012] If the electronic unlocking method fails, after the end of the handle and the abutting end of the swing pawl come into contact, the handle needs to be pulled further. The handle will rotate to a larger angle, moving within the mechanical unlocking range. This rotation moves the cable, which pulls the mechanical locking mechanism of the lock, thus achieving mechanical unlocking. During the mechanical unlocking rotation, the end of the handle pushes the abutting end of the swing pawl, causing it to rotate on the handle seat. The swing pawl does not obstruct the handle's rotation. Upon successful unlocking, the handle returns to its original position under the action of the first spring, and simultaneously, the swing pawl returns to its original position under the action of the second spring.

[0013] The above solution offers the following advantages: 1. The first and second springs are not coaxial; they are separate and can be assembled independently, reducing assembly difficulty and improving production efficiency. 2. The swing pawl design makes the boundary between electronic and mechanical unlocking methods clearer. During normal electronic unlocking, when the handle is rotated to the point of contact with the abutment, the resistance is greater, allowing passengers to clearly feel the resistance and preventing over-rotation that could pull the cable. 3. When the handle rotates within the electronic unlocking range, the end of the handle does not contact the abutment. The swing pawl and second spring do not contribute resistance; only the first spring provides resistance, making rotation easier and less strenuous. Significant resistance only occurs when the swing pawl contacts the end of the handle, creating a distinct difference in resistance and providing passengers with a clearer feel and control.

[0014] Preferably, as an improvement, the handle base is provided with a first support part, and the swing pawl is rotatably connected to the first support part, with the abutting end of the swing pawl bent towards the handle. Thus, the abutting end bends towards the handle and faces the tail of the handle, ensuring that after the handle is rotated at a certain angle, the tail of the handle can abut against the abutting end of the swing pawl.

[0015] Preferably, as an improvement, the first support and the swing pawl are rotatably connected via a pivot. Thus, by setting the pivot, a rotatable connection between the first support and the swing pawl is achieved.

[0016] Preferably, as an improvement, the second-position spring is a torsion spring, which is sleeved on the rotating shaft. Using a torsion spring for the second-position spring and sleeved on the rotating shaft reduces the space occupied by the second-position spring and makes the structure more compact and reasonable.

[0017] Preferably, as an improvement, the swing pawl is provided with a spring clearance space, and the torsion spring is located in the spring clearance space. Thus, by providing the spring clearance space, the swing pawl can avoid the second-stage spring, making the second-stage spring and the swing pawl more compact. At the same time, the second-stage spring does not need to be located on the outside of the swing pawl, resulting in a more reasonable spatial arrangement and less space occupied by the second-stage spring.

[0018] Preferably, as an improvement, the handle base is provided with a second support part, and the second support part and the handle are rotatably connected by a spindle. Thus, by setting the spindle, the rotatable connection between the second support part and the handle is achieved.

[0019] Preferably, as an improvement, the first-position spring is a torsion spring, which is sleeved on the mandrel. Using a torsion spring for the first-position spring and sleeved on the mandrel reduces the space occupied by the first-position spring, resulting in a more compact and rational structural design.

[0020] Preferably, as an improvement, it also includes a resistance device with a resistance gear connected to it, and a gear part on the handle, which meshes with the resistance gear. Thus, when the handle is released and springs back, the gear part and the resistance gear mesh, the resistance device reduces the rotational speed of the resistance gear, thereby slowing down the speed at which the handle springs back to its original position and ensuring the stability of the handle's spring-back reset.

[0026] Figure 6 for Figure 2 Enlarged view of a local structure. Detailed Implementation

[0027] The following detailed description illustrates the specific implementation methods:

[0028] The reference numerals in the accompanying drawings include: handle base 1, handle 2, resistance 3, resistance gear 4, gear part 5, first gear spring 6, spindle 7, first support part 8, second gear spring 9, rotating shaft 10, swing pawl 11, abutting end 12, cable 13, pulling part 14, cover 15, micro switch 16, rotating part 17.

[0029] The basic implementation examples are as follows: Figures 1-6 As shown: An electromechanical dual unlocking structure includes a handle base 1, a handle 2 rotatably mounted on the handle base 1, a micro switch 16, and a first-position spring 6 for resetting the handle 2.

[0030] In this embodiment, the rotation of the handle 2 and the handle base 1 is specifically as follows: a second support portion is integrally provided on the handle base 1, and a connecting portion is integrally provided on the back of the handle 2. The second support portion and the connecting portion of the handle 2 are rotatably connected by a spindle 7. The spindle 7 can be integrally connected to the connecting portion of the handle 2, with the spindle 7 and the second support portion rotatably arranged; alternatively, the spindle 7 can be fixedly arranged to the second support portion, with the spindle 7 and the connecting portion of the handle 2 rotatably arranged; or the spindle 7 can be independent of the connecting portion and the second support portion of the handle 2, passing through both the connecting portion and the second support portion. In this embodiment, the first spring 6 is a torsion spring, sleeved on the spindle 7. One end of the torsion spring is connected to the handle base 1, and the other end is connected to the handle 2. Thus, when the handle 2 is pulled, it rotates around the spindle 7 on the handle base 1, allowing the second spring 9 to store force.

[0031] The handle 2 has a rotating part 17, the rotation center line of which is collinear with the center line of the spindle 7. A micro switch 16 is fixed to the back of the handle base 1 by screws, and the probe of the micro switch 16 contacts the rotating part 17. Thus, when the handle 2 rotates around the spindle 7, the handle 2 drives the rotating part 17 to rotate, causing relative movement between the rotating part 17 and the probe of the micro switch 16, allowing the micro switch 16 to detect the rotation of the handle 2.

[0032] The electromechanical dual unlocking structure in this embodiment also includes a swing pawl 11 rotatably mounted on the handle base 1 and a second spring 9 providing resistance to the rotation of the swing pawl 11. The end of the swing pawl 11 is an abutting end 12, which is opposite to the tail end of the handle 2. Specifically, the rotation of the swing pawl 11 and the handle base 1 is as follows: a first support portion 8 is integrally provided on the back of the handle base 1. There are two first support portions 8, which are opposite to each other. The swing pawl 11 is located between the two first support portions 8, and the swing pawl 11 and the first support portions 8 are rotatably connected by a rotating shaft 10. The rotating shaft 10 can be integrally fixed with the swing pawl 11 and rotatably mounted on the first support portion 8; or, the rotating shaft 10 is integrally fixed with the first support portion 8 and rotatably mounted on the swing pawl 11; or, the rotating shaft 10 is independent of the first support portion 8 and the swing pawl 11, and the rotating shaft 10 passes through the first support portion 8 and the swing pawl 11, and the rotating shaft 10 is not fixed to the first support portion 8 or the swing pawl 11. In this embodiment, the end of the swing claw 11 away from the rotating shaft 10 is the abutting end 12, which bends towards the handle 2. The abutting end 12 and the tail end of the handle 2 ( Figure 1 (The left end of the middle handle 2) is opposite.

[0033] In this embodiment, the second spring 9 is a torsion spring, which is sleeved on the rotating shaft 10. Specifically, the swing pawl 11 has a spring clearance space, and the torsion spring is located in the spring clearance space. The torsion spring is located between the two first support parts 8. One end of the torsion spring is connected to the handle seat 1, and the other end of the torsion spring is connected to the swing pawl 11. With this configuration, the structure of the second spring 9, the swing pawl 11, and the rotating shaft 10 is reasonably and compactly arranged.

[0034] In this embodiment, when the handle 2 rotates within the rotation range of electronic unlocking, the tail end of the handle 2 and the abutting end 12 are in a separated state; when the handle 2 rotates within the rotation range of mechanical unlocking, the tail end of the handle 2 and the abutting end 12 are in abutting state.

[0035] This embodiment also includes a resistance device 3, which is fixed to the handle seat 1 by screws. A resistance gear 4 is connected to the resistance device 3. A gear part 5 is provided on the handle 2. The rotation center line of the gear part 5 is collinear with the center line of the spindle 7. The gear part 5 and the resistance gear 4 mesh.

[0036] A pull part 14 is integrally fixed to the back of the handle 2. A pull cable 13 is connected to the pull part 14. The end of the pull cable 13 away from the handle 2 is connected to the mechanical lock part of the car lock.

[0037] In addition, a cover 15 is also attached to the back of the handle base 1 to cover the hole on the handle base 1 where the handle 2 is located, so as to prevent the structure on the back of the handle base 1 from being seen through the hole on the handle base 1.

[0038] The specific implementation process is as follows: Normally, handle 2 is placed flat in the hole of handle seat 1, and the door lock is in the locked state.

[0039] To unlock the car door locks, pull handle 2. Figure 1 The right end of handle 2 is tilted upwards. Handle 2 rotates on handle seat 1, and rotates around spindle 7 as the center of rotation. Handle 2 first rotates within the rotation range of electronic unlocking. Handle 2 drives rotating part 17 to rotate together. Rotating part 17 slides relative to the probe. Micro switch 16 detects the rotation of handle 2. The electronic lock part of the door lock receives the rotation signal of handle 2 and automatically unlocks, allowing the door to open. During this process, the tail end of handle 2 does not abut against the abutting end 12 of swing pawl 11, making the rotation of handle 2 relatively effortless and easy. At the same time, after handle 2 rotates, the first-position spring 6 stores power.

[0040] As handle 2 continues to rotate, its tail end abuts against the abutting end 12. The swing pawl 11, under the action of the second-position spring 9, provides resistance to the rotation of handle 2. At this point, the resistance is significant, and once the passenger feels a noticeable resistance, they will stop pulling on handle 2 and release it. Handle 2 will then rotate in the opposite direction to reset under the action of the first-position spring 6. Since the passenger does not continue to pull on handle 2, it will not unlock mechanically.

[0041] If the electronic unlocking method fails and unlocking cannot be performed electronically, during rotation within the electronic unlocking range, once the tail end of handle 2 abuts against the abutting end 12 of the swing pawl 11, a greater force needs to be applied to continue pulling handle 2, increasing its rotation angle. As handle 2 rotates within the mechanical unlocking range, it drives the pull cable 13 to move, which in turn pulls the mechanical locking mechanism of the lock, thus achieving mechanical unlocking. During rotation within the mechanical unlocking range, the tail end of handle 2 pushes against the abutting end 12 of the swing pawl 11. Figure 4 The swing pawl 11 rotates on the handle seat 1. Figure 4 The swing pawl 11 rotates clockwise around the pivot 10 without obstructing the rotation of the handle 2, while the second spring 9 stores energy. When unlocking is successful, the handle 2 is released, and the handle 2 returns to its original position under the action of the first spring 6. At the same time, the swing pawl 11 also rotates in the opposite direction to return to its original position under the action of the second spring 9.

[0042] In this embodiment, the rotation angle range of the electronic unlocking handle 2 (calculated from when the handle 2 has never been pulled) can be specifically set to 0-30°, and the rotation angle range of the mechanical unlocking handle 2 (calculated from when the handle 2 has never been pulled) can be specifically set to 30-45°. Therefore, when the handle 2 rotates within the 0-30° range, the tail end of the handle 2 does not abut against the abutting end 12 of the swing pawl 11, and the resistance to the rotation of the handle 2 is basically only the resistance of the first-stage spring 6. The resistance to the rotation of the handle 2 is relatively small, and the handle 2 rotates more easily and effortlessly. If the handle 2 rotates within the 30-45° range, then the tail end of the handle 2 abuts against the abutting end 12 of the swing pawl 11, and the second-stage spring 9 will provide resistance to the rotation of the swing pawl 11. The swing pawl 11 transmits the resistance to the handle 2, and the resistance to the rotation of the handle 2 is greater. Thus, passengers will feel a distinct difference in feel at the two boundaries of electronic and mechanical unlocking rotation.

[0043] In this embodiment, the second spring 9 and the first spring 6 are not coaxially arranged, which facilitates installation and reduces the difficulty and cost of assembly.

[0044] In addition, after the handle 2 is released, the handle 2 rotates in the opposite direction to reset. However, the setting of the resistance device 3 makes the resistance gear 4 rotate at a slower speed. As a result, the rotation speed of the gear part 5 is slower, and the handle 2 resets more slowly, avoiding abnormal noise or damage caused by the fast reset speed of the handle 2.

[0045] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
