Description

Technical Field

[0001] The utility model relates to a front hood locking mechanism of an automobile and the vehicle, belonging to the technical field of automobile parts. Background Art

[0002] The front hood lock is a critical component in the vehicle's cab, ensuring the proper locking and unlocking of the front hood. Due to its operational characteristics, the front hood lock is susceptible to severe impact during use, which can cause deformation of the lock body and latch, as well as wire breakage and loss, potentially leading to lock failure.

[0003] When the front cover cannot be closed, the problem can be solved by replacing the lock body, lock buckle, etc. However, if the front cover cannot be opened or is stuck, it will be difficult to maintain, which will have a significant impact on the inspection and maintenance of the car's front components.

[0028] In the description of the present invention, it should be understood that the terms "upper" and "lower" etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the protection content of the present invention.

[0029] like Figure 1-Figure 5 As shown, a car front hood lock mechanism includes a base 2, a lock body assembly, a lock catch 11, a rubber buffer 7, a forced opening column 10 and an upper cover plate 1;

[0030] The lock body assembly is mounted on the base 2, and the lock body assembly includes a lock tongue 3 and a pawl 4. The lock tongue 3 is connected to the lock buckle 11. Specifically, a lock tongue shaft 5 and a pawl shaft 8 are mounted on the base 2. The end of the lock tongue shaft 5 is rotatably mounted with the lock tongue 3. The lock tongue shaft 5 is provided with a lock tongue spring 6 for limiting the lock tongue 3. The end of the pawl shaft 8 is rotatably mounted with the pawl 4. The pawl shaft 8 is provided with a pawl spring 9 for limiting the pawl 4. The cooperation of the pawl 4 can realize the locking and unlocking of the lock body itself, and the lock tongue 3 and the lock buckle 11 can realize the locking and unlocking of the front cover. With the lock tongue shaft 5 and the pawl shaft 8 as the rotation center, when the lock tongue 3 is turned, the pawl 4 rotates accordingly. After reaching the critical point, the pawl 4 rebounds under the action of the pawl spring 9, completing the limit of the lock tongue 3 and realizing the locking function; after locking, when the pawl 4 is turned to the critical point, the lock tongue 3 rebounds under the action of the lock tongue spring 6, and the front cover lock is unlocked;

[0031] The rubber buffer 7 is mounted on the base 2 and is located between the lock tongue 3 and the pawl 4. The rubber buffer 7 is used to buffer and limit the lock tongue 3, the pawl 4 and the lock buckle 11, thereby improving the impact resistance of the lock body and extending the service life of the lock body.

[0032] The forced opening column 10 is installed on the pawl 4. When the pawl 4 cannot be opened due to deformation of the lock body, wire drawing, etc., the front cover can be forcibly opened by pulling the forced opening column 10;

[0033] The upper cover 1 is snap-connected to the base 2 to protect the lock body assembly and the rubber buffer 7. The upper cover 1 and the base 2 are easy to assemble and disassemble.

[0034] In some embodiments, as Figure 1 、 Figure 3 As shown, the rubber buffer 7 includes a lock catch buffer block 702 located on the lower side and a lock bolt pawl buffer block 701 located on the upper side. The lock bolt pawl buffer block 701 has a mounting hole 703, and the base 2 is provided with a mounting block 201 that cooperates with the mounting hole 703. The rubber buffer 7 is snapped onto the mounting block 201 of the base 2 through the mounting hole 703, ensuring stable installation and convenient assembly and disassembly.

[0035] In some embodiments, as Figure 3 As shown, the latch pawl buffer block 701 is provided with a pawl buffer surface 704 that cooperates with the pawl 4 and a latch buffer surface 705 that cooperates with the latch 3. The buckle buffer block 702 is provided with a buckle buffer surface 706 that cooperates with the buckle 11. The buffering principle of the rubber buffer 7 is as follows: Figure 4 As shown, when the front mask is closed, the lock buckle 11 drives the lock tongue 3 to move inward. Under the action of external force, the lock tongue 3 and the lock buckle 11 collide with the lock tongue buffer surface 705 on the lock tongue pawl buffer block 701 and the lock buckle buffer surface 706 on the lock buckle buffer block 702 respectively. The kinetic energy is absorbed by the rubber buffer 7 to avoid the rigid impact of the moving parts and the lock body; at the same time, the pawl 4 first rotates clockwise under the drive of the lock tongue 3, and after exceeding the critical point, it rebounds under the action of the pawl spring 9 and hits the pawl buffer surface 704 on the lock tongue pawl buffer block 701, completing the kinetic energy absorption and improving the service life.

[0036] In some embodiments, as Figure 3 As shown, the lock tongue pawl buffer block 701 and the lock catch buffer block 702 are integrally formed, which makes processing more convenient.

[0037] In some embodiments, as Figure 1 、 Figure 2As shown, the base 2 is provided with a strong opening hole 202 that cooperates with the strong opening column 10. The strong opening hole 202 is provided with a closed position and a strong opening position. When the pawl 4 cannot be opened due to deformation of the lock body, wire drawing, etc., you can put your hand into the gap between the front mask and the front outer panel, pull the strong opening column 10, and pull the strong opening column 10 from the closed position to the open position to forcibly open the front mask. Figure 5 shown.

[0038] Finally, the utility model also provides a vehicle, on which the automobile front hood lock mechanism is installed.

[0039] The automobile front hood lock mechanism of the utility model has a forced opening function and is impact-resistant. The rubber buffer member cushions and limits the moving parts of the lock tongue, the ratchet and the external matching part lock buckle, thereby extending the service life of the lock body. The forced opening column installed on the ratchet can forcibly open the front hood when the front hood lock ratchet fails to work normally, thereby reducing the impact caused by the failure of the front hood lock, effectively improving maintenance efficiency and reducing economic losses.

[0040] Furthermore, those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, combinations of features from different embodiments are also intended to fall within the scope of protection of the present invention and form different embodiments. For example, in the above embodiments, those skilled in the art will be able to use them in combination based on the known technical solutions and the technical problems to be solved by this application.
