Description
Technical Field
[0001] The utility model relates to the field of automobiles, in particular to a double-pull front cover lock for an automobile. Background Art
[0002] In traditional car design, the hood usually refers to the covering part of the engine compartment. Its main function is to protect the engine and its related components from the intrusion of dust, moisture and other external factors. At the same time, the hood also plays an aesthetic and aerodynamic role, helping to enhance the overall appearance and performance of the vehicle. Structurally, the hood is connected to the body through a hinge and is equipped with a locking system to keep it stably closed during driving.
[0003] A traditional hood lock usually includes an unlocking handle, a main lock body and a lock catch located in the cab, wherein the unlocking handle in the cab is used to unlock the hood from the inside, the main lock body is usually installed on the vehicle body, and the lock catch is usually installed on the inner surface of the hood corresponding to the main lock body. Through the coordinated locking action of the main lock body and the lock catch, the hood can be firmly locked in the closed position.
[0004] In addition, in the traditional design of automobile hood locks, a multi-level locking mechanism is usually used to ensure that the hood will not be accidentally opened due to vibration or other external forces when driving at high speeds. It usually includes a main lock and at least one safety lock to provide additional security. For example, an additional safety hook is set. When the user pulls the unlocking handle in the cab, walks to the front of the car to manually open the second safety hook, and finally lifts the hood. In traditional fuel vehicles, since the frequency of opening the hood is relatively low, this design is sufficient to meet the needs of daily use.
[0005] However, with the popularity of new energy vehicles, the design and use of car hoods have changed significantly. New energy vehicles often design the space under the hood as storage space to adapt to the layout without traditional engines, thereby providing users with additional storage convenience. During use, users need to access this storage space more frequently, which greatly increases the frequency of opening the hood.
[0006] In this new usage context, the shortcomings of traditional car hood locks begin to emerge. First, the operation process of traditional car hood locks is relatively cumbersome, requiring the user to pull the unlocking handle in the cab, then walk to the front of the car to manually open the two safety hooks, and finally lift the hood. This process is not only time-consuming, but also in some cases it can be laborious, especially for users with less strength or when the hood needs to be opened quickly in an emergency.
[0007] Additionally, the complexity of conventional hood locks may cause accelerated wear of the mechanical components of conventional hood locks when faced with frequent opening and closing motions, thereby increasing maintenance costs and potential risk of failure, while also increasing assembly time and total part cost.
[0008] Therefore, it is necessary to improve the structure of the traditional automobile front cover lock so that it can be better adapted to be used as a cover lock structure of the front storage space of new energy vehicles. Utility Model Content

DETAILED DESCRIPTION
[0033] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a double-pull front cover lock for an automobile of the utility model in conjunction with the accompanying drawings.
[0034] The utility model can be applied to the cover of the front storage space of new energy vehicles, solving the technical problem that the structure and operation process of traditional automobile front cover locks are relatively complicated and unsuitable as the cover lock of the front storage space of new energy vehicles.
[0035] Specifically, the automobile described in this application document can be used to refer to all types of vehicles, such as fuel-powered vehicles, electric vehicles (including pure electric vehicles, plug-in hybrid vehicles and extended-range electric vehicles) and other new energy types of vehicles, such as hydrogen fuel cell vehicles.
[0036] Example 1, please refer to Figures 1 to 3 Based on the technical problems solved above, the present embodiment discloses a double-pull front hood lock for automobiles, comprising a ratchet 100 and a pawl 200 capable of engaging with the ratchet 100, wherein the ratchet 100 and the pawl 200 can be driven by external forces respectively and rotate around a ratchet shaft 104 and a pawl shaft 203, wherein a first torsion spring 105 is sleeved on the ratchet shaft 104, and a second torsion spring 204 is sleeved on the pawl shaft 203;
[0037] The ratchet 100 is provided with a first meshing portion 101 and a second meshing portion 102 adjacent to each other, and correspondingly, the pawl 200 is provided with a third meshing portion 201, and the third meshing portion 201 can mesh with the first meshing portion 101 or the second meshing portion 102; the ratchet 100 is also provided with a first stop portion 103, and correspondingly, the pawl 200 is also provided with a second stop portion 202;
[0038] When the pawl 200 rotates and drives the third meshing portion 201 to disengage from the first meshing portion 101 , the second stop portion 202 can contact the first stop portion 103 to prevent the ratchet 100 from rotating toward the unlocking position.
[0039] The automobile double-pull front cover lock in this solution has a primary locking and secondary unlocking function. Correspondingly, the ratchet 100 and the pawl 200 can be in the locking position, the first unlocking position and the second unlocking position respectively; when locking, the ratchet 100 and the pawl 200 are both in the locking position; when unlocking, the ratchet 100 and the pawl 200 are first rotated to the primary unlocking position, and then rotated to the secondary unlocking position;
[0040] The locking process of this embodiment is:
[0041] When locking, the ratchet 100 rotates toward the upper locking position, at which time the first meshing portion 101 of the ratchet 100 abuts against the third meshing portion 201, and drives the pawl 200 to rotate toward the upper locking position until the first meshing portion 101 meshes with the third meshing portion 201, and the ratchet 100 and the pawl 200 reach the upper locking position, and at the same time, the first torsion spring 105 is tightened to store elastic potential energy;
[0042] The unlocking process of this embodiment is:
[0043] When the first unlocking is performed, the external force drives the pawl 200 to rotate in the positive direction toward the first unlocking position, so that the third meshing portion 201 drives the ratchet 100 to rotate through the first meshing portion 101 until the second stop portion 202 contacts the first stop portion 103. At this time, the third meshing portion 201 is disengaged from the first meshing portion 101, and at the same time, the second torsion spring 204 is tightened to store elastic potential energy.
[0044] Then, the external force is removed, and the pawl 200 is driven to rotate in the opposite direction under the elastic restoring force of the second torsion spring 204, releasing the ratchet 100. The ratchet 100 continues to rotate under the elastic restoring force released by the first torsion spring 105 until the third meshing portion 201 meshes with the second meshing portion 102. At this time, the ratchet 100 and the pawl 200 are both in the first unlocking position;
[0045] During the second unlocking, the external force continues to drive the pawl 200 to rotate forward, the third meshing portion 201 disengages from the second meshing portion 102, releasing the ratchet 100, and canceling the external force. The pawl 200 rotates in the opposite direction to the second unlocking position under the action of the elastic restoring force released by the second torsion spring 204, and the ratchet 100 continues to rotate to the second unlocking position under the action of the elastic restoring force released by the first torsion spring 105, thereby realizing the complete unlocking of the double-pull front cover lock of the car.
[0046] For new energy vehicles with storage space at the front of the vehicle, in the face of frequent opening and closing of the front cover, this solution has a simple structure and is easy to operate. The user only needs to use external force to drive the ratchet to rotate twice to complete the complete unlocking of the front cover. This solution is suitable as a cover lock for the storage space at the front of new energy vehicles and can adapt to the frequent opening and closing of the storage space at the front of the vehicle. This solution simplifies the number of parts, saves assembly time, reduces the total parts cost, and reduces weight, making the opening of the car front cover more time-saving and labor-saving, and greatly improves the convenience and efficiency of operation without sacrificing safety.
