The front cover assembly, also called engine cover assembly, is a relatively independent assembly in the vehicle body structure, is a necessary passage for users to check and maintain the power system, and mainly consists of a front cover welding assembly and a front cover accessory (mainly consisting of a front cover locking system, a sealing strip, a stay bar or the like).

In an embodiment of the present application, a vehicle is provided, referring to fig. 1 and 2, which includes a vehicle body, a cowl assembly 1, a front end frame 4, and a cowl lock system. Wherein, the front cover plate assembly 1 comprises a front cover inner plate 12 and a front cover outer plate 11 which are at least partially attached and fixedly connected with each other; a front end frame 4 mounted on the vehicle body and located below the front cover plate assembly 1; a front hood lock system is provided between the front hood inner panel 12 and the front end frame 4 for unlocking or locking the front hood panel assembly 1 and the front end frame 4. The front cover lock system provided by the embodiment of the application has the advantage of small space occupation in the X direction and the Z direction of the vehicle body.

With the development of vehicle technology and popularization of pedestrian protection requirements, higher requirements are put on the arrangement of a front hood lock system. Among these, pedestrian protection requirements are mainly modeled as collisions with vehicles during the pedestrian crossing the road. Firstly, the lower leg of a pedestrian collides with a front bumper or a headlight, then the pedestrian can generate a movement of flying upwards obliquely towards a front cover plate, and the upper leg collides with the front bumper and a front cover; finally, the pedestrian falls down along the vehicle surface, and the head collides with the front surface of the vehicle (front hood, fender, front windshield, window trim, a-pillar, etc.).

In some embodiments, referring to fig. 1 and 2, the front cover assembly 1 includes a front cover inner plate 12 and a front cover outer plate 11, where the front cover inner plate 12 and the front cover outer plate 11 are at least partially fixedly connected in a fitting manner, specifically may refer to that the front cover inner plate 12 and the front cover outer plate 11 are fixedly connected in a fitting manner along two ends of a vehicle body in a length direction, and a cavity is formed between the front cover inner plate 12 and the front cover outer plate 11, and the cavity structure may partially absorb impact energy generated by a manner of collapsing and deforming into a cavity space when the vehicle is impacted, so as to reduce the head of a pedestrian when the pedestrian impacts the front cover assembly 1, so as to meet the requirement of pedestrian protection.

Further, in some embodiments, referring to fig. 1, 3 and 4, a front cover latch reinforcement 13 is further provided between the front cover inner panel 12 and the front cover outer panel 11, the front cover latch reinforcement 13 is provided between the front cover outer panel 11 and the front cover inner panel 12, and the front cover latch is provided close to the front cover inner panel 12. Specifically, one end of the front cover latch reinforcement 13, which is far from the front end frame 4, is fixedly connected with one end of the front cover inner plate 12, which is far from the front end frame 4, and the other end of the front cover latch reinforcement 13 is a free end. So arranged, on the one hand, the connection reliability of the front cover lock pin assembly 2 and the front cover inner plate 12 is enhanced; on the other hand, the strength and torsional rigidity of the cowl assembly 1 can be improved, and the impact energy generated during the collision of the vehicle can be partially absorbed.

The manner of fixing the front cover latch reinforcement 13 to the front cover inner panel 12 is not limited, and the two may be fixed by bolts or welded. Preferably, in some embodiments, referring to fig. 3 and 4, an end of the front cover latch reinforcement 13 remote from the front end frame 4 is provided with a weld area a welded to the front cover inner panel 12, facilitating welding together.

The front cover lock system is an important functional part for ensuring the running safety of the vehicle, is arranged in front of the vehicle body, ensures the fitting of the front cover of the vehicle and the vehicle body under the action of the front cover lock, is in a completely locked state in the running process of the vehicle, and prevents the safety problem of obstructing the sight of a driver caused by the opening of the front cover of the vehicle due to accidents. Whether the front cover lock system is properly arranged is related to the structural safety and service life of the parts, and influences on subjective operation experience of customers. In addition, with the development of vehicle technology and popularization and application of pedestrian protection requirements, higher requirements are put on the structure and arrangement of the front cover lock system.

Among them, there are various forms of front cover locks in the front cover lock system, and the present method mainly includes welding the lock pin to the front cover plate, which has the disadvantage that the lock pin cannot be adjusted, and the gap and the offset between the front cover and the front bumper and between the front cover and the front fender are difficult to adjust, and sometimes the front cover plate must be deformed and bent to ensure the gap and the offset. Thus, in embodiments of the present application, the locking pin is mounted in a non-welded manner.

The arrangement of the front hood lock is important for the vehicle, since the position in which the front hood lock is located and the functions it is required to perform relate to driving safety. The rationality of its arrangement directly influences whether the lock body can fully perform its function during use of the vehicle. In the usual related art, the arrangement of the front cowl lock often follows the following principle: for example, the lock body and the lock catch meshing center are positioned on the center surface in the width direction of the vehicle so as to ensure that the deviation of the gravity center can not occur when the front cover of the vehicle is closed, otherwise, the problems of lock catch deformation, excessive abrasion of the lock body and the lock catch, interference between the front cover and the metal plate of the vehicle body and the like can occur when the lock catch is used for a long time, and the service life of parts is influenced; for another example, the axis of the lock catch is required to be perpendicular to the engagement direction, namely, the falling direction of the lock catch is required to be perpendicular to the lock body, otherwise, when the lock catch collides with the lock body, component force in other directions can be generated, and the structure of the lock body can be damaged; and in addition, the extension line of the lock catch axis is generally intersected with the center of the hinge axis of the front cover, namely the falling track of the lock catch is required to be tangent with a circle taking the center of the hinge axis of the front cover as the center of a circle, and the lock catch is ensured to be vertically meshed with the lock body. The above is an adaptive arrangement for improving the reliability of the front cover lock structure, where reliability may refer to that the wear degree between the lock catch and the lock body meets the requirement of the service cycle and the normal use requirement. However, the present application is not limited to the above manner, and the abrasion between the lock catch and the lock body can be changed by changing the hardness of the lock catch and the lock body to meet the reliability requirement of the front cover lock, for example, the hardness of the lock catch is matched with the hardness of the card interface for clamping the lock catch, where the hardness matching can refer to that the hardness of the lock catch and the hardness of the card interface are close; or a principle of 'hard to soft' is adopted, such as that the lock catch adopts a material with higher hardness, the clamping interface matched with the lock catch in a clamping way adopts a material with lower hardness relative to the lock catch, in a word, the abrasion degree between the lock catch and the lock body in the front cover lock system can meet the reliability requirement of the front cover lock system, namely, the front cover lock is not necessarily limited in the prior art to be obliquely arranged so as to meet the normal reliability requirement of the front cover lock.

Due to the arrangement scheme of the front cover lock, the structure of the inner and outer plates of the front cover sheet metal, the front cover lock pin installation position and the front cover lock and lock pin selection are determined. On the other hand, in a car in which the front portion of the vehicle (front bumper and front cover) is compact, the space for disposing the front cover lock is very limited in a condition in which the cooling module 6 in the cabin of the car body is disposed forward with reference to fig. 1, 3 and 4. The existing vehicle type front cover lock system is arranged vertically and tangentially through the hinge axis according to the engagement point of the lock body, the front cover lock is obliquely arranged in the front-rear direction of the vehicle, the oblique cooling module 6 below the lock body occupies large space in the X direction (the width direction of the vehicle body) and the Z direction (the height direction of the vehicle body). Therefore, based on the fact that the front cover lock system is limited in space in the front-rear and vertical directions of the vehicle body, the embodiment of the application focuses on solving the problem of space optimization in the X direction and the Z direction.

To this end, an embodiment of the present application provides a front cowl lock system, referring to fig. 1 and 2, for bringing the front cowl assembly 1 and the front end frame 4 into an unlocked or locked state. The front hood lock system includes a front hood lock pin assembly 2 and a front hood lock assembly 3. Wherein, the front cover lock pin assembly 2 is used for being connected with the front cover plate assembly 1; the front cover lock assembly 3 is used for being connected with the front end frame 4; the front cover lock assembly 3 is provided with two lock panels 31 which are arranged in an alignment way, wherein one lock panel 31 is used as a mounting surface to be mounted on the front end frame 4; the two lock panels 31 are vertically arranged, and the planes of the two lock panels 31 are perpendicular to the first direction; wherein the first direction is consistent with the length direction of the vehicle body.

Specifically, a front hood lock system is located at the front end of the vehicle, the front hood lock system including a front hood lock pin assembly 2 and a front hood lock assembly 3, the front hood lock pin assembly 2 being connected to the front hood panel assembly 1, the front hood lock assembly 3 being connected to the front end frame 4. Here, the specific structures of the front cover latch assembly 2 and the front cover lock assembly 3 are not limited, and it suffices that the front cover latch assembly 2 and the front cover lock assembly 3 are in an unlocked or locked state between the front cover plate assembly 1 and the front end frame 4 by engagement and disengagement. The front cover lock assembly 3 has two lock panels 31 disposed in alignment, wherein one lock panel 31 is mounted on a side wall of the front end frame 4 facing the lock panel 31 as a mounting surface.

In the related art, the front cover lock is arranged obliquely relative to the front end frame 4 or the front cover plate assembly 1, namely, the front cover lock is obliquely arranged in the front-rear direction of the vehicle, and the lower part of the lock body of the front cover lock is obliquely arranged on the front end frame 4 or the cooling module 6 of the vehicle, so that the front cover lock system occupies larger vehicle body length direction and vehicle body vertical direction, and the arrangement space of parts in the cabin is limited.

In the application, the two lock panels 31 of the front cover lock assembly 3 are vertically arranged, and the planes of the two lock panels 31 are perpendicular to the first direction, so that the front cover lock assembly 3 is arranged in the positive X direction of the vehicle body, namely, the two lock panels 31 and the X direction are vertically distributed. The front hood lock assembly 3 is arranged in the positive X direction, so that the space occupation of the lock panel 31 of the front hood lock assembly 3 in the front-rear direction can be reduced, the gap between the lock body of the front hood lock assembly 3 and the front position of the cooling module 6 can be increased, and the possibility of forward movement of the cooling module 6 is provided under the condition that the installation position of the front hood lock assembly 3 is ensured, such as the cooling module 6 can be moved in the front direction, thereby providing more space for arranging parts in the cabin of the vehicle, and increasing the space volume in the X direction of the vehicle body for a storage box in the cabin of the vehicle body. In addition, in the case where the front cowl lock assembly 3 is arranged in the positive X direction, a smaller-sized front cowl lock may be selected to further reduce the space occupation of the lock panel 31 of the front cowl lock assembly 3 in the front-rear direction.

The X direction is a direction aligned with the first direction, that is, the longitudinal direction of the vehicle body. The X-direction is given for convenience of description of the arrangement direction of the front hood lock assembly 3. For example, as in fig. 1, 3 and 4, the X direction refers to the longitudinal direction of the vehicle body, i.e., the first direction; the Z direction refers to the height direction of the vehicle body.

It should be noted that, the embodiment of the present application is not limited to the specific manner of the matching connection between the front cover lock assembly 3 and the front cover lock assembly 2, and it is only required that the front cover lock assembly 2 and the front cover lock assembly 3 are engaged and separated to make the front cover plate assembly 1 and the front end frame 4 in an unlocked or locked state, that is, the front cover assembly can be opened and locked. For example, the front cover latch assembly 2 includes a bent piece to form a latch that is mounted to the front cover plate assembly 1 by a mounting portion; the front cover lock assembly 3 comprises a shell, a ratchet wheel tension spring, a pawl and the like, wherein a clamping interface for clamping the lock catch is arranged on the ratchet wheel; when the front cover is required to be closed, the lock catch pushes the ratchet wheel to rotate, the ratchet wheel tension spring stretches under the action of rotation of the ratchet wheel, and finally the lock catch is clamped in the clamping interface to realize locking of the front cover plate assembly 1, and when the front cover plate assembly 1 is required to be opened, the pawl releases the limit of the ratchet wheel, and the ratchet wheel tension spring pulls the ratchet wheel to rotate so as to push the lock catch upwards until the lock catch is separated from the clamping interface.

In some embodiments, referring to fig. 4 and 5, the front cover latch assembly 2 includes a latch body 22 and a latch base 21, the latch body 22 being fixedly attached vertically to the latch base 21; the front cover plate assembly 1 comprises a front cover inner plate 12 and a front cover outer plate 11 which are fixedly connected in a fitting manner at least partially, and a side wall of a lock pin bottom plate 21, which is away from a lock pin body 22, is fixedly connected with the front cover inner plate 12. The specific structure of the lock pin body 22 is not limited, and for example, the lock pin body 22 may be a lock pin body 22 with a U-shaped cross section, or may be a circular lock pin body 22. The shape and size of the lock pin bottom plate 21 are not limited, and they may satisfy the installation space of the lock pin body 22.

In some embodiments, referring to fig. 1, 4 and 5, the latch body 22 includes a cross bar 221 disposed along a first direction, a first solid and a second upright 223, the first upright 222 and the second upright 223 standing on both ends of the cross bar 221 along a length direction thereof, respectively; the two ends of the first upright 222 and the second upright 223 far from the cross bar 221 are respectively and fixedly connected to the lock pin bottom plate 21. The arrangement is such that the latch body 22 forms a latch body 22 shape of U-shaped cross section, and because the cross bar 221 is arranged along the first direction and the first stand column 222 and the second stand column 223 are arranged upright at both ends of the cross bar 221, the U-shaped cross section of the latch body 22 is parallel to the first direction, that is, the latch body 22 is arranged along the first direction, so as to be in matched connection with the front cover lock assembly 3 arranged along the first direction and the latch body 22.

Referring to fig. 1, 4 and 5, in the first direction, the second stand column 223 is disposed close to the front end frame 4, the first stand column 222 is disposed away from the front end frame 4, and the length of the second stand column 223 is greater than the length of the first stand column 222; the plane of the latch bottom plate 21 is inclined to the first direction, and the inclined direction of the latch bottom plate 21 is directed from the first upright 222 to the second upright 223.

Continuing with reference to fig. 1, 4 and 5, a side wall of the latch bottom plate 21 facing away from the latch body 22 is fixedly attached to the inner wall of the front cover inner plate 12. Here, the contact area between the latch bottom plate 21 and the front cover inner plate 12 can be increased by adopting the manner of bonding and fixing connection, so that the integrity after connection is improved.

Wherein, for the arrangement that the plane of the lock pin bottom plate 21 is included with the first direction, and the inclined direction of the lock pin bottom plate 21 is directed from the first upright 222 to the second upright 223, on the one hand, in order to provide the welding surface width space between the inner front cover lock pin reinforcement 13 of the front cover assembly 1 and the front cover inner plate 12, namely, the welding area a in fig. 3 and 4; on the other hand, since the plane of the front cover inner panel 12 is not generally parallel to the first direction and is inclined upward toward the front end frame 4, the latch bottom panel 21 is inclined upward toward the front end frame 4 in order to attach and fix the latch bottom panel 21 to a side wall of the front cover inner panel 12 facing away from the front cover outer panel 11. Further, since the latch bottom plate 21 is inclined upward toward the front end frame 4, if the lengths of the first and second columns 222 and 223 are the same on the premise that the cross bar 221 of the latch body 22 is disposed in the first direction, it is apparent that the end of the second column 223, which is close to the front end frame 4 and is far from the front hood lock assembly 3, is difficult to be directly fixedly connected with the latch bottom plate 21, and thus the length of the second column 223, which is close to the front end frame 4, is designed to be greater than the length of the first column 222.

In some embodiments, referring to fig. 1, 5 and 6, a through hole is formed in the latch bottom plate 21, and a connection hole is formed at a position corresponding to the front cover inner plate 12 in the through hole, so that the latch bottom plate 21 and the front cover inner plate 12 are fixedly connected through the fastener 5 sequentially passing through the through hole and the connection hole. The through hole on the latch bottom plate 21 and the connecting hole on the front cover inner plate 12 can be threaded holes, the fastener 5 can be a screw rod matched with the threaded holes and provided with external threads, and the screw rod sequentially penetrates through the through hole and is connected with the latch bottom plate 21 and the front cover inner plate 12 in a threaded mode. In this way, the latch bottom plate 21 can be easily detached from the front cover inner plate 12, so that the front cover latch assembly 2 can be easily replaced.

Specifically, in some embodiments, referring to fig. 1, 5 and 6, the through hole on the latch bottom plate 21 and the connecting hole on the front cover inner plate 12 may be threaded holes, and the fastener 5 may be a threaded rod with external threads matching the threaded holes, and the threaded rod sequentially passes through the through hole and connects the latch bottom plate 21 and the front cover inner plate 12. In this way, the latch bottom plate 21 can be easily detached from the front cover inner plate 12, so that the front cover latch assembly 2 can be easily replaced.

In some embodiments, referring to fig. 1, 5 and 6, the through holes include a first through hole 211 and a second through hole 212, wherein the first through hole 211 is a circular hole, the second through hole 212 is an elongated hole, and the fastener 5 is a bolt that is mated with the first through hole 211 and the second through hole 212. Wherein, the front cover inner plate 12 is provided with connecting holes corresponding to the first through holes 211 and the second through holes 212, respectively. The first through hole 211 is a circular hole, so that a bolt matched with the circular hole passes through the circular hole to connect the lock pin bottom plate 21 to the front cover inner plate 12, then the second through hole 212 and the second connecting hole correspondingly pass through the second through hole 212 and the second connecting hole in sequence, and finally the two bolts are respectively screwed to fixedly connect the lock pin bottom plate 21 with the front cover inner plate 12. Wherein the second through hole 212 is designed as an elongated hole, so as to absorb the installation error.

In some embodiments, referring to fig. 1, 5 and 6, the outer edge of the latch base 21 has a flange 213, the flange 213 of the flange 213 being directed toward the latch body 22. Among these, the flange 213 structure on the outer edge of the latch base 21 is utilized to increase the strength of the front cover latch base 21 and to increase the aesthetic appearance of the front cover latch.

Referring to fig. 3, 5 and 6, the lock pin base 21 has two protrusions 214 on a side facing the lock pin body 22, and one ends of the first and second columns 222 and 223 near the lock pin base 21 are fixedly connected to the protrusions 214, respectively. Wherein, the convex part 214 can reduce the contact area between the lock pin bottom plate 21 and the front cover inner plate 12, so that the lock pin bottom plate 21 is convenient to be attached to the front cover inner plate 12; on the other hand, the latch base 21 is typically limited in thickness, if it is difficult to weld or screw, rivet, etc. directly onto the latch base 21 of limited thickness with the first and second posts 222, 223, such as by riveting the first and second posts 222, 223 with the latch base 21, the presence of the projection 214 may facilitate providing a rivet plane for the first and second posts 222, 223, thereby facilitating the connection of the latch base 21 with the first and second posts 222, 223.

Here, the protruding portion 214 may be a protruding portion 214 formed by forming a through hole in the lock pin bottom plate 21 and then welding around the wall of the through hole toward the lock pin body 22, or a protruding portion 214 formed by directly recessing the lock pin bottom plate 21 toward the lock pin body 22, and the specific forming manner is not limited.
