DETAILED DESCRIPTION

[0043] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0044] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0045] The engine hood lock structure and the vehicle are described in detail below through specific embodiments:

[0046] Reference Figures 1 to 17 As shown, some embodiments of the utility model provide an engine hood lock structure, including a bracket 1, a clamping plate 2, a stop plate 3 and a pull wire, wherein the pull wire is connected to the stop plate 3 so as to pull the stop plate 3 to move.

[0047] Among them, the card plate 2 is rotatably connected to the bracket 1, and a first tension spring 4 is connected between one end of the card plate 2 and the bracket 1, that is, the card plate 2 can rotate relative to the bracket 1 and can also be reset under the action of the first tension spring 4, and the stop plate 3 is rotatably connected to the bracket 1, and a second tension spring 5 is connected between one end of the stop plate 3 and the bracket 1, that is, the stop plate 3 can rotate relative to the bracket 1 and can also be reset under the action of the second tension spring 5.

[0048] In specific implementation, two locking protrusions 6 are provided on one of the card plate 2 and the stop plate 3, and a pawl 7 is provided on the other. The pawl 7 can be switchably abutted with any one of the two locking protrusions 6, or released from the abutment with the locking protrusion 6. It can be understood that when the pawl 7 abuts with any one of the two locking protrusions 6, the stop plate 3 and the card plate 2 limit each other and can form a two-level unlocking structure. When the pawl 7 releases the abutment with the locking protrusion 6, unlocking can be achieved, and then the engine hood is opened.

[0049] The engine hood lock structure disclosed in the present invention utilizes the first tension spring 4 and the second tension spring 5 to realize the reset of the card plate 2 and the stop plate 3. Compared with the torsion spring that can only be set on one side of the card plate 2 or the stop plate 3, the first tension spring 4 and the second tension spring 5 can cover the thickness of the card plate 2 and the stop plate 3, and at least can save the space occupied by the card plate 2 and the stop plate 3, thereby reducing the thickness of the engine hood lock structure and improving space utilization.

[0050] Furthermore, the bracket 1 does not need to be provided with structures such as a rotating shaft required for installing a torsion spring, which can simplify the structure of the bracket 1 and reduce the weight when necessary to meet the lightweight requirements of the vehicle.

[0051] In some embodiments, reference Figure 2 As shown, a first fixing portion 21 is provided on the card plate 2, and the first fixing portion 21 is arranged on the side of the card plate 2 away from the bracket 1. The first tension spring 4 is connected to the first fixing portion 21, which can further reduce the thickness between the card plate 2 and the bracket 1 occupied by the first tension spring 4, and at the same time, the space on the side of the card plate 2 away from the bracket 1 can be utilized, and the setting position of the first tension spring 4 is relatively flexible.

[0052] A second fixing portion 31 is provided on the stop plate 3, and the second fixing portion 31 is arranged on the side of the stop plate 3 away from the bracket 1. The second tension spring 5 is connected to the second fixing portion 31 to further reduce the thickness between the stop plate 3 and the bracket 1 occupied by the second tension spring 5. At the same time, the space on the side of the stop plate 3 away from the bracket 1 can also be utilized, and the setting position of the second tension spring 5 is relatively flexible.

[0053] That is to say, by disposing the first fixing portion 21 and the second fixing portion 31 , the space inside the engine hood lock structure can be fully utilized, thereby improving space utilization and reducing the thickness of the engine hood lock structure.

[0054] In some embodiments, the pawl 7 is arranged opposite to the locking protrusion 6; one end of the first tension spring 4 is connected to the bottom end of the card plate 2, and the other end is connected to the bracket 1 on the side where the stop plate 3 is located, so as to generate a first elastic force between the card plate 2 and the bracket 1; one end of the second tension spring 5 is connected to the bottom end of the stop plate 3, and the other end is connected to the bracket 1 on the side where the card plate 2 is located, so as to generate a second elastic force between the stop plate 3 and the bracket 1; wherein, the first elastic force and the second elastic force are in opposite directions.

[0055] Reference Figure 3 As shown, the directions of the arrows are respectively the directions of the first elastic force and the second elastic force, and the directions of the first elastic force and the second elastic force are opposite, so that the clamping plate 2 and the stop plate 3 can maintain an abutment state, thereby ensuring that the engine hood lock structure can remain locked.

[0056] In specific implementation, one end of the first tension spring 4 is connected to the bottom end of the card plate 2, and one end of the second tension spring 5 is connected to the bottom end of the stop plate 3. With this arrangement, the top end of the card plate 2 and the top end of the stop plate 3 can move relative to each other and open, thereby unlocking the engine hood lock structure.

[0057] Of course, it is understandable that a first tension spring 4 is connected between one end of the card plate 2 and the bracket 1, and a second tension spring 5 is connected between one end of the stop plate 3 and the bracket 1. After the card plate 2 is opened to the maximum angle, the first tension spring 4 is supported between the bottom end of the card plate 2 and the bracket 1. After the stop plate 3 is opened to the maximum angle, the second tension spring 5 is supported between the bottom end of the stop plate 3 and the bracket 1. In other words, the opening angle between the card plate 2 and the stop plate 3 can be limited by the support of the first tension spring 4 and the second tension spring 5.

[0058] In some embodiments, the two locking protrusions 6 include a primary locking protrusion 61 and a secondary locking protrusion 62. During the unlocking process of the engine hood lock structure, the pawl 7 sequentially has a locking position abutting against the primary locking protrusion 61, an intermediate position abutting against the secondary locking protrusion 62, and an unlocking position where the abutment with the secondary locking protrusion 62 is released.

[0059] That is to say, referring to Figure 3 As shown, the pawl 7 first abuts against the primary locking protrusion 61, and the pawl 7 is in the locking position. Figure 4 As shown, the pull wire pulls the stop plate 3 to rotate. When the pawl 7 is released from the abutment with the primary locking protrusion 61, as the card plate 2 and the stop plate 3 rotate, Figure 6 As shown, the pawl 7 can abut against the secondary locking protrusion 62, and the pawl 7 is in the middle position. Figure 7 As shown, as the card plate 2 and the stop plate 3 continue to rotate, the pawl 7 is released from the contact with the secondary locking protrusion 62, and the pawl 7 is in the unlocked position. Figure 8 As shown, the latch on the hood can be disengaged from the hood lock structure, thereby opening the hood.

[0060] On the contrary, refer to Figures 9 to 12 As shown, the engine hood is manually pressed so that the pawl 7 abuts against the secondary locking protrusion 62 and the primary locking protrusion 61 in sequence until the pawl 7 abuts against the first locking protrusion 6 to lock the lock buckle on the engine hood.

[0061] Specifically, refer to Figure 3 and Fig.13As shown, the pull wire pulls the stop plate 3 so that the stop plate 3 can overcome the second elastic force and rotate along the first direction, wherein the first direction is clockwise or counterclockwise. After the stop plate 3 and the card plate 2 are released from abutment, the first elastic force can pull the card plate 2 to rotate along the first direction, and the primary locking protrusion 61 and the secondary locking protrusion 62 are arranged in sequence in the opposite direction of the first direction. With such a configuration, the pawl 7 can respectively abut against the primary locking protrusion 61 and the secondary locking protrusion 62 in sequence during the unlocking process until the unlocking is finally achieved.

[0062] For example, refer to Figure 3 As shown, the pull wire pulls the stop plate 3 to overcome the second elastic force and rotate in the counterclockwise direction, and the primary locking protrusion 61 and the secondary locking protrusion 62 are arranged in sequence in the clockwise direction. Under the action of the first elastic force, when the card plate 2 rotates in the counterclockwise direction, the pawl 7 can abut against the primary locking protrusion 61 and the secondary locking protrusion 62 in sequence to achieve unlocking.

[0063] Reference Fig.13 As shown, the pull wire pulls the stop plate 3 to overcome the second elastic force and rotate in the clockwise direction, and the primary locking protrusion 61 and the secondary locking protrusion 62 are arranged in sequence in the counterclockwise direction. Under the action of the first elastic force, when the card plate 2 rotates in the clockwise direction, the pawl 7 can abut against the primary locking protrusion 61 and the secondary locking protrusion 62 in sequence to achieve unlocking.

[0064] When implementing it, refer to Fig.13 As shown, the pawl 7 first abuts against the primary locking protrusion 61, and the pawl 7 is in the locking position. Fig.14 As shown, the pull wire pulls the stop plate 3 to rotate. When the pawl 7 is released from the abutment with the primary locking protrusion 61, as the card plate 2 and the stop plate 3 rotate, Fig.16 As shown, the pawl 7 can abut against the secondary locking protrusion 62, and the pawl 7 is in the middle position. Fig.17 As shown, as the clamping plate 2 and the stop plate 3 continue to rotate, the pawl 7 is released from the abutment with the secondary locking protrusion 62. At this time, the pawl 7 is in the unlocked position, and the lock buckle on the engine hood can be disengaged from the engine hood lock structure, thereby opening the engine hood.

[0065] Of course, it should be noted that the primary locking protrusion 61 and the secondary locking protrusion 62 may also be arranged in other ways, which is not limited in the present disclosure and may be specifically arranged according to actual conditions.

[0066] In some embodiments, a locking groove 8 is provided on the card plate 2 or the stop plate 3, which is used to lock the lock on the engine hood. When the pawl 7 is in the locking position, the groove wall of the locking groove 8 is extended in the horizontal direction to limit the lock on the engine hood in the vertical direction through the horizontal groove wall to prevent the lock from falling out of the locking groove 8. When the pawl 7 is in the unlocking position, the notch of the locking groove 8 is vertically upward so that the lock can fall out of the locking groove 8.

[0067] Of course, the locking groove 8 can also be other structural forms, and the present disclosure does not limit this, as long as it can prevent the lock buckle from falling out when the pawl 7 is in the locking position, and can guide the lock buckle to fall out when the pawl 7 is in the unlocking position.

[0068] Reference Figure 5 and Fig.15 As shown, the stop plate 3 is provided with a buffer hook 32, and the stop plate 3 is provided with a limit hook 22. When the pawl 7 is switched from the locked position to the middle position, the limit hook 22 can abut against the buffer hook 32 to limit the rotation angle of the clamping plate 2 and the stop plate 3, so as to prevent the clamping plate 2 and the stop plate 3 from opening too much and affecting the abutment of the pawl 7 with the primary locking protrusion 61 and the secondary locking protrusion 62. In specific implementation, the buffer hook 32 is set at the top of the stop plate 3, and the limit hook 22 is set at the top of the stop plate 3 to avoid interference with the release of the lock buckle.

[0069] In some embodiments, a limiting convex edge 11 is provided at the edge of the bracket 1. When the pawl 7 is released from the locking protrusion 6, the clamping plate 2 and the stop plate 3 can be limited by the limiting convex edge 11 to limit the opening angle between the clamping plate 2 and the stop plate 3, thereby avoiding the situation where the pawl 7 is completely separated from the limiting protrusion and cannot be locked.

[0070] Reference Figure 2 As shown, the bracket 1 is provided with a first rotating shaft 12 and a second rotating shaft 13 at intervals, the card plate 2 is provided with a first through hole 23, the first rotating shaft 12 is penetrated in the first through hole 23, the stop plate 3 is provided with a second through hole 33, the second rotating shaft 13 is penetrated in the second through hole 33. It should be noted that, compared with the structure using a torsion spring, the first rotating shaft 12 and the second rotating shaft 13 do not need to be adapted to the torsion spring for size setting, which can simplify the structure of the bracket 1 and reduce the weight when necessary to meet the lightweight requirements of the vehicle.

[0071] Some other embodiments of the present disclosure provide a vehicle including an engine hood lock structure as described in any of the above embodiments.

[0072] The vehicle provided in the embodiment of the present disclosure includes the engine hood lock structure of any of the above embodiments, and thus has the beneficial effects of the engine hood lock structure of any of the above embodiments, which will not be described in detail here.
