Description

Technical Field

[0001] The utility model belongs to the technical field of automobile door locks, and specifically relates to a high-safety, impact-resistant door lock assembly for new energy vehicles. Background Art

[0002] As people's living standards continue to improve, cars have gradually entered thousands of households and become a common means of transportation. People's requirements for vehicle comfort have also greatly increased. Car doors also play a vital role in vehicles. Inconvenient operation can affect the user's mood. Door locks on car doors usually include an inner opening assembly, an outer opening assembly, and a lock body. The inner opening assembly is located on the inside of the car door, the outer opening assembly is located on the outside of the car door, and the lock body is located inside the car door. The inner opening assembly, the outer opening assembly, and the lock body are linked by a connecting rod. The applicant found that the existing outer opening assembly is relatively complex in structure, has many components, is complicated to install, and has high production costs.

[0003] To this end, a simple automotive door lock assembly with the publication number "CN104652996A" is available. The assembly comprises a housing, a handle, a pull rod, a rocker arm, a torsion spring, and a rocker arm pivot pin. The handle's upper end is pivotally mounted on the housing, while a pull arm at its lower end extends inward through the housing. A rocker arm bracket is positioned inwardly at the bottom of the housing. The middle portion of the rocker arm and the torsion spring are riveted to the rocker arm bracket via the rocker arm pivot pin. The torsion spring's two legs are fixed to the rocker arm and rocker arm bracket, respectively. The pull rod is riveted to the upper portion of the rocker arm, and a slide is provided at the lower portion of the rocker arm, into which the pull arm slides. This assembly offers advantages such as a simple structure, ease of installation, and low production cost.

[0004] However, for the above-mentioned simple car door lock outward opening assembly, although the torsion spring is arranged between the rocker arm bracket and the rocker arm to return the rocker arm, one leg of the torsion spring is fixed on the lower side of the rocker arm bracket, and the other leg is fixed on the inner side of the rocker arm, there are still the following more obvious defects during use: when the rocker arm uses the torsion spring to rebound, since there is no component to guide and limit the swing direction of the rocker arm, it is easy for the rocker arm to get stuck on the door lock bowl during the rebound process, resulting in the problem that the inward opening door lock cannot be closed or opened, which in turn affects the safety of the vehicle's door lock. Utility Model Content

[0005] The purpose of the present utility model is to provide a high-safety anti-impact door lock assembly for new energy vehicles to solve the problems raised in the above-mentioned background technology.

[0008] A reinforced guide fan plate is fixed to one end of the rocker arm support and has an arc guide groove on its surface which is slidingly connected to the main rocker arm guide. The rocker arm support is provided with an adjustment slide lock groove for adjusting the position of the main rocker arm, and a guide slide lock rod is slidingly provided in the adjustment slide lock groove which is connected to the main rocker arm through a rotating shaft seat.

[0009] Preferably, a connecting drive rod is fixed to the middle of the main rocker arm, and a torsion spring is sleeved on one end of the connecting drive rod, so that the main rocker arm can make the inner door opening wrench rebound to its initial state during the process of swinging the inner door unlocking.

[0010] Preferably, the guide sliding locking rod is provided with a locking nut at one end of the side of the rocker arm support, and the other end of the guide sliding locking rod is connected to one end of the connecting driving rod on the main rocker arm through a rotating shaft seat, and the other end of the torsion spring is fixedly connected to one side of the guide sliding locking rod, which guides the swing of the main rocker arm, avoids jamming, and serves as an anti-impact support.

[0011] Preferably, a reinforced guide limit column is provided on the side surface of one end of the main rocker arm, and the reinforced guide limit column is movably connected in the arc guide groove for stable guided sliding, which is beneficial to the swing of the main rocker arm for internal unlocking.

[0012] Preferably, a strip-shaped through-groove is provided at the other end of the main rocker arm, and a connecting column is provided at one end of the driving arm, and the connecting column slides within the strip-shaped through-groove to realize the driving connection between the main rocker arm and the driving arm for internal unlocking.

[0013] Preferably, one end of the driving arm is movably mounted on one side of the door lock bowl through a pin shaft, and one end of the driving arm passes through a slot cavity provided on the door lock bowl and is connected to the inner door lock handle to realize the inner unlocking of the new energy vehicle.

[0014] Compared with the existing technology, the technical effects and advantages of the utility model are as follows: the high-security anti-impact door lock assembly of the new energy vehicle is characterized by: the main rocker arm movably connected to the rocker arm support, and the main rocker arm has a reinforced guide limit column, the reinforced guide limit column slides in the arc guide groove, and the reinforced guide fan plate supports the main rocker arm, so that when the main rocker arm is opened or closed by the inner door lock handle, the main rocker arm uses the reinforced guide limit column to limit the position according to the swing amplitude in the arc guide groove, so that the main rocker arm always maintains the same swing range for rocker arm movement during the swinging process, thereby making the car door lock more stable and firm during the inner opening, and thus the problem of the main rocker arm being stuck in the offset direction during the inner opening of the door lock will not occur, further improving the safety and stability of the inner opening of the car door lock.

[0015] By reinforcing the guide sector plate and utilizing the arc-shaped guide groove to support and slide the reinforced guide limit column, the function of the main rocker arm in reinforcing the guide support during shaking can be strengthened, thereby avoiding the main rocker arm from being deformed due to force when the car door lock is impacted by external force, further enhancing the overall support strength and anti-impact effect of the main rocker arm, and when the main rocker arm is subjected to a large impact force, the guide lock rod will unlock and slide in the adjustment slot to reduce the impact force on the car door lock linkage structure.
