Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an electric suction door lock with an inward-opening handle, which can be used in engineering vehicles. Background Technology

[0002] In today's booming automotive industry, electric suction door locks, as key components for ensuring vehicle safety and user convenience, are constantly evolving in technology. Currently, the vast majority of electric suction door locks are equipped with advanced electronic systems to achieve intelligent functions such as remote unlocking and automatic locking, greatly enhancing the user experience.

[0003] Electronically controlled electric door locks offer significant advantages. With a remote key, users can easily open or close the doors from a distance without manual operation. This convenience is especially important when carrying items in both hands. Furthermore, the electronic system can be integrated with other vehicle safety systems, such as the anti-theft alarm system, to issue an alert promptly when abnormal opening is detected, thus enhancing vehicle security.

[0004] However, the electronically controlled electric door locks have also revealed many problems. First, in terms of reliability, the electronic system is extremely complex, consisting of a large number of electronic components and precision circuits. It has stringent requirements for the working environment. Electromagnetic interference, drastic temperature changes, abnormal humidity, and other factors can all affect the performance of electronic components and cause malfunctions. For example, in hot summers or cold winters, electronic components may experience performance degradation or even damage due to overheating or overcooling, causing the car door to fail to open or close properly.

[0005] Secondly, the normal operation of the electronic system is highly dependent on the vehicle's power supply. Once the vehicle battery is depleted, the power line malfunctions, or the fuse blows, the electronically controlled power-closing door locks will immediately fail, leaving the user unable to open the door. This could have serious consequences in an emergency, such as being unable to open the door when needing to quickly access emergency items inside. Utility Model Content

[0006] The purpose of this utility model is to provide an electric suction door lock with an inward-opening handle that is easy to operate and can improve the overall reliability and stability of the electric suction door lock.

[0007] An electric suction door lock with an inward-opening handle includes a base plate. The base plate is provided with a rotatable lever, a toggle element, a toggle block, and a lock hook. The lever, toggle element, toggle block, and lock hook can all automatically reset. The lever is perpendicular to the toggle element and movably connected to the toggle element. The toggle element is movably connected to the toggle block, and the toggle block is movably connected to the lock hook. By moving the lever, the toggle element can be driven to deflect, and the toggle element drives the toggle block to deflect, thereby driving the lock hook to deflect, thus realizing manual unlocking.

[0008] In the above scheme, when the electric suction door lock is in the locked state, the lever, actuating element, lever block, and lock hook are all in their initial positions. Since they can all automatically reset, they will remain in this state without external force, ensuring the door is stably locked. When manual unlocking is required, the user applies external force to the lever to rotate it. Because the lever is perpendicular to and movably connected to the actuating element, the rotation of the lever transmits force to the actuating element, causing it to deflect. During this deflection, the actuating element, through its movable connection with the lever block, transmits its own motion to the lever block, causing... The lever also deflects accordingly. This deflection, through its connection with the locking hook, causes the hook to deflect as well. The deflection of the locking hook changes its engagement with other locking mechanisms on the door, thus unlocking the door. This purely mechanical structure enables manual unlocking without relying on electronic systems or other complex electrical equipment. Even in the event of electronic system malfunction, battery failure, or other abnormalities, the door can still be unlocked manually by operating the lever, ensuring that the door can be opened normally under various conditions. This improves the overall reliability and stability of the electric suction door lock, and it is simple and convenient to operate.

[0009] Furthermore, the base plate includes an integrally formed first mounting plate and a second mounting plate, the first mounting plate and the second mounting plate being L-shaped, the lever being mounted on the first mounting plate, and the actuating element, the lever block and the locking hook being mounted on the second mounting plate.

[0010] In the above solution, the one-piece molding design eliminates the gaps and weak points that may be caused by the connection of multiple components. In the interior of the vehicle door, the space is usually quite compact. The L-shaped design of the first and second mounting plates allows the lever, toggle, block, and lock hook to be arranged on different planes, avoiding mutual interference between components and realizing the compact installation of each component of the electric suction door lock. This leaves more space for the arrangement of other components inside the vehicle door and improves the space utilization rate.

[0011] Furthermore, the lever includes a main rod and a handle. The main rod has a first groove and a second groove on both sides. The first mounting part has a first limiting shaft and a second limiting shaft corresponding to the positions of the first groove and the second groove.

[0012] In the above design, the handle provides a comfortable and easy-to-grip part for the user. When manual unlocking is required, the user can more easily and naturally grip the handle to turn the lever, reducing the difficulty of operation and improving the convenience of operation. Even in emergency situations or for users with less hand strength, the unlocking action can be completed smoothly. The cooperation between the first groove, the second groove, the first limiting shaft, and the second limiting shaft provides an effective limiting effect for the rotation of the main lever. When the lever rotates, the first limiting shaft moves in the first groove, and the second limiting shaft moves in the second groove. The length and shape of the groove determine the rotation range of the lever. This design avoids excessive rotation of the lever and prevents damage to other components of the electric suction door lock due to excessive rotation angle of the lever, ensuring the normal operation and service life of all components of the electric suction door lock.

[0013] Furthermore, a first return spring is installed on the first mounting plate, and the main rod is connected to the first return spring.

[0014] In the above solution, after the user manually operates the lever to unlock the car door, the first return spring will use its own elastic restoring force to drive the main lever back to the initial position. This automatic reset feature greatly improves the user's operating convenience. The user does not need to manually return the lever to its original position, which simplifies the operation process, saves time and effort, and makes the use of the car door easier and faster.

[0015] Furthermore, the actuating element includes a first actuating arm and a second actuating arm, the first actuating arm being in movable contact with the lever, and the second actuating arm being in movable contact with the lever block.

[0016] In the above scheme, the first actuating arm movably abuts against the lever, effectively transmitting the force generated by the lever's rotation to the actuating element. When the user manually operates the lever, the lever's movement is accurately transmitted to the actuating element via the first actuating arm, enabling the actuating element to respond promptly to the lever's action. Then, the second actuating arm movably abuts against the lever block, further transmitting the force received by the actuating element to the lever block, ultimately controlling the lock hook and completing the unlocking or locking action of the car door. This force transmission method is efficient and direct, reducing energy loss during transmission and improving the operational efficiency of the electric suction door lock. Furthermore, the base plate is provided with a support block, on which a first connecting shaft, a second connecting shaft, a second return spring and a third return spring are installed. The first connecting shaft and the second connecting shaft pass through the lever and the locking hook respectively and are connected to the second mounting plate. The lever and the locking hook are respectively connected to the second return spring and the third return spring.

[0017] In the above scheme, the first connecting shaft and the second connecting shaft pass through the toggle block and the lock hook respectively and are connected to the second mounting plate. This connection method allows the toggle block and the lock hook to be rotatably installed in the electric suction door lock structure. The cooperation of the support block, the first connecting shaft and the second connecting shaft can effectively resist external forces, prevent the toggle block and the lock hook from loosening or shifting, ensure the accurate relative position between the components of the electric suction door lock, and maintain the stability of the overall structure of the electric suction door lock. The second return spring and the third return spring are connected to the toggle block and the lock hook respectively, providing the power for the toggle block and the lock hook to return.

[0018] Furthermore, it also includes a top plate, which covers the bottom plate, and the ends of the first connecting shaft and the second connecting shaft away from the second mounting plate are connected to the top plate.

[0019] In the above solution, the top plate is placed on the bottom plate, which encapsulates the various components inside the electric suction door lock in a relatively closed space, creating a complete structural system. This closed structure integrates key components such as the toggle block, lock hook, and toggle mechanism, preventing external debris and dust from entering the electric suction door lock. This reduces the risk of component damage or malfunction due to interference from debris, and improves the overall reliability and durability of the electric suction door lock.

[0020] This utility model discloses an electric suction door lock with an inward-opening handle, which has the advantages of simple operation and improved overall reliability and stability. When manual unlocking of the car door is required, the user applies external force to the lever to rotate it. Since the lever is perpendicular to the actuating component and is movably connected to it, the rotation of the lever transmits force to the actuating component, driving it to deflect. During the deflection process, the actuating component transmits its own motion to the actuating block through its movable connection, causing the actuating block to deflect as well. The deflection of the actuating block further drives the lock hook to deflect through its movable connection with the lock hook. The deflection of the lock hook changes its engagement with other locking structures of the car door, thereby unlocking the car door. The manual unlocking function is achieved using a purely mechanical structure, without relying on electronic systems or other complex electrical equipment. Even in the event of electronic system failure, battery depletion, or other abnormalities, the car door can still be unlocked by manually operating the lever, ensuring that the car door can be opened normally under various conditions. This improves the overall reliability and stability of the electric suction door lock and makes it simple and convenient to operate. Attached Figure Description

[0027] The electric suction door lock with an inward-opening handle of this utility model will be described in further detail below with reference to specific embodiments and accompanying drawings.

[0028] like Figure 1 As shown in a preferred embodiment, the electric suction door lock with an inward-opening handle of this utility model includes a base plate 1. The base plate 1 is provided with a rotatable lever 2, a toggle member 3, a toggle block 4, and a lock hook 5. The lever 2, the toggle member 3, the toggle block 4, and the lock hook 5 can all automatically reset. The lever 2 is perpendicular to the toggle member 3 and is movably connected to the toggle member 3. The toggle member 3 is movably connected to the toggle block 4, and the toggle block 4 is movably connected to the lock hook 5. By toggling the lever 2, the toggle member 3 can be driven to deflect, and the toggle member 3 drives the toggle block 4 to deflect, thereby driving the lock hook 5 to deflect, thereby realizing manual unlocking.

[0029] In this embodiment, when the electric suction door lock is in the locked state, the lever 2, the toggle 3, the toggle block 4 and the lock hook 5 are all in their respective initial positions, and since they can all automatically reset, they will remain in this state without external force, ensuring that the door is in a stable locked state.

[0030] When the car door needs to be unlocked manually, the user applies external force to the lever 2 to make it rotate. Since the lever 2 is perpendicular to the actuating element 3 and is movably connected to the actuating element 3, the rotation of the lever 2 will transmit force to the actuating element 3, driving the actuating element 3 to deflect. During the deflection process, the actuating element 3 transmits its own motion to the actuating block 4 through the movable connection with the actuating block 4, causing the actuating block 4 to also deflect. The deflection of the actuating block 4 further drives the actuating hook 5 to deflect through the movable connection with the locking hook 5. The deflection of the locking hook 5 changes its cooperation state with other locking structures of the car door, thereby realizing the unlocking of the car door.

[0031] The manual unlocking function is achieved by adopting a purely mechanical structure, without relying on electronic systems or other complex electrical equipment. Even in the event of electronic system failure, battery depletion, or other abnormalities, the door can still be unlocked by manually operating lever 2, ensuring that the door can be opened normally under various circumstances. This improves the overall reliability and stability of the electric suction door lock, and it is simple and convenient to operate.

[0032] like Figure 2 As shown, in some embodiments, the base plate 1 includes an integrally formed first mounting plate 101 and a second mounting plate 102. The first mounting plate 101 and the second mounting plate 102 are L-shaped. The lever 2 is mounted on the first mounting plate 101, and the actuating element 3, the toggle block 4, and the locking hook 5 are mounted on the second mounting plate 102. The integral design eliminates gaps and weak points that may occur when connecting multiple components. In the interior of a vehicle door, the space is usually quite compact. The L-shaped design of the first mounting plate 101 and the second mounting plate 102 allows the lever 2, the actuating element 3, the toggle block 4, and the locking hook 5 to be arranged on different planes, avoiding mutual interference between components. This achieves compact installation of the various components of the electric suction door lock, leaving more space for the arrangement of other components inside the vehicle door and improving space utilization.

[0033] like Figure 2 As shown, in some embodiments, the lever 2 includes a main rod portion 21 and a handle portion 22. The main rod portion 21 has a first groove 211 and a second groove 212 on both sides. The first mounting portion has a first limiting shaft 6 and a second limiting shaft 7 at the positions corresponding to the first groove 211 and the second groove 212. The handle 22 provides a comfortable and easy-to-grip part for the user. When manual unlocking is required, the user can more easily and naturally grip the handle 22 to turn the lever 2, reducing the difficulty of operation and improving the convenience of operation. Even in emergency situations or for users with less hand strength, the unlocking action can be completed smoothly. The cooperation between the first groove 211, the second groove 212 and the first limiting shaft 6 and the second limiting shaft 7 provides an effective limiting effect for the rotation of the main rod 21. When the lever 2 rotates, the first limiting shaft 6 will move in the first groove 211 and the second limiting shaft 7 will move in the second groove 212. The length and shape of the grooves determine the rotation range of the lever 2. This design avoids excessive rotation of the lever 2 and prevents damage to other parts of the electric suction door lock due to excessive rotation angle of the lever 2, ensuring the normal operation and service life of all parts of the electric suction door lock.

[0034] like Figure 2As shown, in some embodiments, a first return spring 8 is installed on the first mounting plate 101, and the main rod 21 is connected to the first return spring 8. When the user manually operates the lever 2 to unlock the car door, the first return spring 8 will use its own elastic restoring force to drive the main rod 21 back to its initial position. This automatic reset feature greatly improves the user's operational convenience. The user does not need to manually return the lever 2 to its original position, which simplifies the operation process, saves time and effort, and makes the use of the car door easier and faster.

[0035] like Figure 3 As shown, in some embodiments, the actuating element 3 includes a first actuating arm 31 and a second actuating arm 32. The first actuating arm 31 movably abuts against the lever 2, and the second actuating arm 32 movably abuts against the lever block 4. The first actuating arm 31, movably abutting against the lever 2, effectively transmits the force generated by the rotation of the lever 2 to the actuating element 3. When the user manually operates the lever 2, the movement of the lever 2 is accurately transmitted to the actuating element 3 through the first actuating arm 31, enabling the actuating element 3 to respond promptly to the action of the lever 2. Then, the second actuating arm 32 movably abuts against the lever 4, further transmitting the force received by the actuating element 3 to the lever 4, ultimately controlling the lock hook 5 and completing the unlocking or locking action of the car door. This force transmission method is efficient and direct, reducing energy loss during transmission and improving the operating efficiency of the electric suction door lock. like Figure 3 and Figure 4 As shown, in some embodiments, a support block 9 is provided on the base plate 1. A first connecting shaft 10, a second connecting shaft 11, a second return spring 12, and a third return spring 13 are mounted on the support block 9. The first connecting shaft 10 and the second connecting shaft 11 pass through the toggle block 4 and the lock hook 5, respectively, and are connected to the second mounting plate 102. The toggle block 4 and the lock hook 5 are connected to the second return spring 12 and the third return spring 13, respectively. The first connecting shaft 10 and the second connecting shaft 11 pass through the toggle block 4 and the lock hook 5, respectively, and are connected to the second mounting plate 102. This connection method allows the toggle block 4 and the lock hook 5 to be rotatably installed in the electric suction door lock structure. The cooperation of the support block 9, the first connecting shaft 10, and the second connecting shaft 11 can effectively resist external forces, prevent the toggle block 4 and the lock hook 5 from loosening or displacing, ensure the accurate relative position between the components of the electric suction door lock, and maintain the stability of the overall structure of the electric suction door lock. The second return spring 12 and the third return spring 13 are connected to the toggle block 4 and the lock hook 5, respectively, providing the power for the toggle block 4 and the lock hook 5 to return.

[0036] like Figure 5As shown, in some embodiments, a top plate 14 is also included, which covers the bottom plate 1. The ends of the first connecting shaft 10 and the second connecting shaft 11 away from the second mounting plate 102 are connected to the top plate 14. The top plate 14 covers the bottom plate 1, so that the various components inside the electric suction door lock are encapsulated in a relatively closed space, forming a complete structural system. This closed structure integrates key components such as the toggle block 4, the lock hook 5, and the actuating element 3, preventing external debris and dust from entering the electric suction door lock, reducing the risk of component damage or malfunction due to interference from debris, and improving the overall reliability and durability of the electric suction door lock.

[0037] This utility model discloses the working principle and process of an electric suction door lock with an inward-opening handle. When the car door needs to be unlocked manually, the user applies external force to the lever 2 to make it rotate. Since the lever 2 is perpendicular to the actuating element 3 and is movably connected to the actuating element 3, the rotation of the lever 2 will transmit force to the actuating element 3, driving the actuating element 3 to deflect. During the deflection process, the actuating element 3 transmits its own motion to the actuating block 4 through its movable connection with the actuating block 4, causing the actuating block 4 to also deflect. The deflection of the actuating block 4 is further connected to the locking hook 5 through its movable connection, causing the locking hook 5 to deflect. The deflection of the locking hook 5 changes its cooperation state with other locking structures of the car door, thereby realizing the unlocking of the car door.
