Technical Field
[0001] This utility model relates to the field of automotive body technology, specifically to a front hood lock and an automobile. Background Technology
[0002] As a crucial component of automobiles, the front hood lock directly impacts the stability of opening and closing the hood. With the increasing number of pure electric vehicles each year, the frequency of hood opening is also gradually increasing, leading to a stronger demand from users for a design that allows the hood to pop up electrically.
[0003] Currently, the two main types of electrically unlocking front cover structures on the market are integrated electrically unlocking front cover locks and separate electrically unlocking front cover devices. In the separate electrically unlocking front cover device, since the front cover unlocking release cable is always under tension, there is no issue of the cable disengaging or failing due to vibration. For integrated electrically unlocking front cover locks, in addition to the electrically unlocking actuator directly connected to the pawl in the front cover lock, there is also a front cover unlocking release cable mechanism on the pawl that enables manual unlocking through the cooperation of the cable and the pawl. However, in the front cover unlocking release cable mechanism, the cable ball head needs to be limited between the cable ball head and the pawl by a cable ball head stop set on the pawl. To make it easier for the cable ball head to be installed into the cable ball head stop, an opening structure is provided at the top of the cable ball head stop.
[0004] In the prior art, the cable ball stop on the pawl is usually designed as an L-shaped groove structure with an opening at the top and a lower part for blocking the cable ball. However, this structure has the following problems: First, when the electric unlocking actuator pulls the pawl directly, the front cover unlocking release cable is in a free and slack state. At this time, the cable ball of the front cover unlocking release cable is easily affected by the vibration of the vehicle body, causing the cable ball to come off from the upper opening of the L-shaped groove structure, resulting in the failure of the front cover unlocking release cable. Second, the notch position of the open L-shaped structure requires high dimensional accuracy. If the deviation is too large, it will also cause the cable ball to come off from the upper opening of the L-shaped groove structure on the pawl. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a car front cover lock and a car, so as to ensure a reliable connection between the front cover unlocking release cable and the pawl, and to prevent the cable from coming off the pawl due to vibration of the car body.
[0006] The car front cover lock provided by this utility model includes a front cover lock base plate and a pawl body rotatably disposed on the front cover lock base plate.

[0007] Furthermore, the first connecting part includes a lower part of the first connecting part, and the anti-detachment structure is an anti-detachment groove with an inverted "U" shape and is disposed in the lower part of the first connecting part. The lower part of the first connecting part includes a first panel for engaging with the front cover lock and a second panel that is angled to the first panel. The two ends of the anti-detachment groove are respectively located on the first panel and the second panel.
[0008] Furthermore, the anti-detachment groove is provided with a mounting hole at its lower end on the second panel for the end of the front cover lock cable to enter the anti-detachment groove, and the diameter of the mounting hole is larger than the diameter of the end of the front cover lock cable.
[0009] Furthermore, it also includes an upper part of the first connecting part, the upper end of the upper part of the first connecting part being connected to the lower end of the pawl body, and the lower end of the upper part of the first connecting part being fixedly connected to the lower part of the first connecting part.
[0010] Furthermore, the first panel is formed by extending outward from the upper lower end of the first connecting portion in a direction away from the front cover lock bottom plate.
[0011] Furthermore, the second panel is formed by extending the first panel from the end away from the pawl body in the opposite direction to the front cover locking cable pull.
[0012] Furthermore, the end of the front cover locking cable is cylindrical, and the length of the end of the front cover locking cable is greater than the diameter of the mounting hole.
[0013] Furthermore, the width of the anti-detachment groove is set to be smaller than the diameter of the end of the front cover locking cable.
[0014] Furthermore, the pawl body is provided with a second connecting part at the lower end of the rotating point for connecting to the output end of the electric unlocking actuator.

Detailed Implementation
[0023] As shown in the figure, the car hood lock provided by this utility model includes a hood lock base plate 1 and a pawl body 2 rotatably mounted on the hood lock base plate 1. The pawl body 2 has a first connecting part at the lower end of the hood lock cable 12 located at the rotation point 6 for connecting with the end of the hood lock cable 5 and cooperating with manual unlocking. The first connecting part has an anti-detachment structure to prevent the end of the hood lock cable 12 from falling off the first connecting part. The upper end of the pawl body 2 cooperates with the buckle on the hood to lock or unlock the hood. The first connecting part at the lower end of the pawl body 2 located at the rotation point 6 is connected to the hood lock cable 5 through the first connecting part. The hood lock is then unlocked by manually pulling the hood lock cable 5. This is prior art and will not be described in detail here. By setting the anti-detachment structure on the first connecting part of the pawl body 2, it is ensured that the end of the hood lock cable 12 is not easily detached from the pawl body 2, thereby avoiding the safety risk of being unable to unlock the hood in an emergency due to the hood lock cable falling off.
[0024] In this embodiment, the first connecting part includes a lower part, and the anti-detachment structure is an anti-detachment groove 9 with an inverted "U" shape and is disposed in the lower part of the first connecting part. The lower part of the first connecting part includes a first panel 7 for engaging with the front cover lock and a second panel 8 set at an angle to the first panel 7. The two ends of the anti-detachment groove 9 are respectively located on the first panel 7 and the second panel 8. The upper end of the upper part 11 of the first connecting part is connected to the lower end of the pawl body 2, and the lower end of the upper part 11 of the first connecting part is fixedly connected to the lower part of the first connecting part.
[0025] The pawl body 2 is constrained by the space limitations of the front cover lock cable 5 and the electric unlocking actuator 4, requiring connection points on the pawl body 2 corresponding to the front cover lock cable 5 and the electric unlocking actuator 4, respectively. Therefore, the lower part of the first connecting part is positioned corresponding to the front cover lock cable 5, and the lower part of the first connecting part is connected to the pawl body 2 through the upper part 11 of the first connecting part. Since the lower part of the first connecting part includes a first panel 7 for engaging with the front cover lock and a second panel 8 set at an angle to the first panel 7, by setting the second panel 8 at an angle to the first panel 7, it can be ensured that the second panel 8 and the first panel 7 are on different planes. Thus, when the front cover lock cable 5 engages with the first panel 7, the second panel 8 has a certain limiting effect on the front cover lock cable 5. Figure 1 As shown, in this solution, the lower part of the first connecting part is set as an L-shaped integral structure (that is, the first panel 7 and the second panel 8 are set perpendicular to each other). This structure is most effective in preventing the end 12 of the front cover locking cable from slipping off the pawl body 2.
[0026] In this embodiment, the anti-detachment groove 9 is provided with a mounting hole 10 at its lower end on the second panel 8 for the front cover lock cable end 12 to enter the anti-detachment groove 9. The diameter of the mounting hole 10 is larger than the diameter of the front cover lock cable end 12. Figure 1 As shown, since the anti-detachment groove 9 is set as an inverted "U" shaped structure, and the two ends of the anti-detachment groove 9 are located on the first panel 7 and the second panel 8 respectively, the front cover locking cable end 12 needs to enter through the mounting hole 10 of the first panel 8 during installation. Then, the front cover locking cable 5 moves upward along the path of the anti-detachment groove 9, then moves horizontally, and finally moves downward and descends to the end of the anti-detachment groove 9 located on the first panel 7 according to gravity. This structure can ensure that the front cover locking cable 5 will not easily slide to the mounting hole 10 of the second panel 8 even in a free and slack state due to vibration, and will not fall off from above like the structure in the prior art. Figure 2 As shown, by setting the diameter of the mounting hole 10 to be larger than the diameter of the front cover lock cable end 12, the front cover lock cable end 12 can be better installed into the anti-detachment groove 9 to achieve connection.
[0027] In this embodiment, the first panel 7 extends outward from the lower end of the upper part 11 of the first connecting portion in a direction away from the front cover lock bottom plate 1; the second panel 8 extends in the opposite direction to the pull of the front cover lock cable 5 from the end of the first panel 7 away from the pawl body 2. Figure 1 and Figure 2As shown, since the first panel 7 is mainly used to connect and cooperate with the front cover lock cable 5 to move the lower part of the first connecting part by pulling the front cover lock cable 5, the first panel 7 must be connected and cooperate with the end 12 of the front cover lock cable. Therefore, the first panel 7 is designed to extend outward from the lower end of the upper part 11 of the first connecting part away from the front cover lock base plate 1. The optimal working state of the first panel 7 is perpendicular to the pawl body 2. In order to prevent the end 12 of the front cover lock cable from slipping off the second panel 8 when the first panel 7 is engaged with the end 12 of the front cover lock cable, the second panel 8 is designed to extend in the opposite direction of the pull of the front cover lock cable 5 from the end of the first panel 7 away from the pawl body 2. At the same time, the mounting point of the front cover lock cable 5 is arranged on the second panel 8 so that the second panel 8 forms a certain obstruction during the sliding process of the front cover lock cable 5. The optimal working state of the second panel 8 is parallel to the pawl body 2.
[0028] In this embodiment, the end 12 of the front cover lock cable is cylindrical, and the length of the end 12 of the front cover lock cable is greater than the diameter of the mounting hole 10; combined with Figure 2 As shown, considering that the front cover locking cable 5 may slide left and right under stress or shift left and right in the free state, and in order to prevent the end 12 of the front cover locking cable from sliding out of the mounting hole 10 on the second panel 8, the end 12 of the front cover locking cable is designed as a cylindrical structure and the length of the end 12 of the front cover locking cable is larger than the diameter of the mounting hole 10. During installation, the end 12 of the front cover locking cable enters perpendicular to the second panel 8, and after installation, the end 12 of the front cover locking cable will not slide out of the mounting hole 10 due to its own length.
[0029] In this embodiment, the width of the anti-detachment groove 9 is smaller than the diameter of the end 12 of the front cover locking cable; combined with Figure 1 As shown, the width of the anti-detachment groove 9 only needs to ensure that the front cover locking cable 5 can pass through during installation. In order to prevent the end 12 of the front cover locking cable from falling out of the anti-detachment groove 9, the width of the anti-detachment groove 9 needs to be set smaller than the diameter of the end 12 of the front cover locking cable.
[0030] In this embodiment, the pawl body 2 is further provided with a second connecting part 3 at the lower end located at the rotation point 6 for connecting with the output end of the electric unlocking actuator 4; combined with Figure 1 and Figure 2As shown, the lower end of the pawl body 2 extends downward to form a second connecting part 3. The second connecting part 3 is mainly used to connect and cooperate with the output end of the electric unlocking actuator 4, so that when the electric unlocking actuator 4 is started, the working end pulls the second connecting part 3 to rotate, thereby realizing the rotation of the pawl body 2 and achieving the electric unlocking function. The connection between the second connecting part 3 and the output end of the electric unlocking actuator 4 can take various forms, such as bolting the second connecting part 3 to the output end of the electric unlocking actuator 4, inserting the second connecting part 3 to the output end of the electric unlocking actuator 4, and sleeve-fitting the second connecting part 3 to the output end of the electric unlocking actuator 4. In this solution, the form of inserting the second connecting part 3 into the output end of the electric unlocking actuator 4 is mainly used. This is the prior art and will not be described in detail here. The second connecting part 3, like the first connecting part, is arranged according to the specific position of the electric unlocking actuator 4.
[0031] This embodiment also provides a car, including the aforementioned car front cover lock; by applying this car front cover lock to the car, the problem of the front cover unlocking release cable vibrating and coming loose from the front cover lock pawl is completely solved, and the safety risk of being unable to unlock in an emergency due to the front cover unlocking release cable vibrating and coming loose is completely avoided; at the same time, this structure also significantly improves the dimensional accuracy of the pawl after forming, effectively improving the assembly problem caused by the pawl processing quality problem.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
