Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and more particularly, to a hook structure and a vehicle. Background Art

[0002] At present, automobile engine hoods (referred to as hoods for short) are generally divided into traditional openable engine hoods and fixed engine hoods that cannot be opened under normal conditions. Among them, the fixed engine hood usually uses a snap hook structure to achieve fixation. At the same time, since the fixed engine hood is smaller in size in the vehicle length direction and larger in size in the vehicle width direction, the snap hook structure is usually arranged in the middle area of the hood. Since this area is also the area where head collisions are likely to occur, a large head crush space is required, that is, the space distance that the hood can be squeezed inward under the action of an external force when a head collision occurs.

[0003] In the prior art, in order to reduce the head injury value of the hood, the head crush space of the hood is usually increased by weakening the hook mounting bracket, but the crush space that can be increased by this method is limited, and it is difficult to meet the requirements of the fixed engine hood for the head crush space. Summary of the Invention

[0004] The problem solved by the present invention is: how to increase the head crush space of the engine hood to reduce the head injury value of the engine hood during a collision.

[0005] To solve the above problems, the present invention provides a hook structure, including a mounting bracket, a hook body, and a base. The mounting bracket is used to be mounted on the inner panel of the engine hood, the base is used to be mounted on the front-end module of the vehicle, a slot is provided on the base, one end of the hook body is clamped with the mounting bracket, and the other end is used to be clamped with the slot. When the hook structure is impacted, the hook body is used to slide along the base, and the mounting bracket is used to collapse along the impact direction.

[0006] Optionally, an induction groove is further provided on the base. The induction groove is located below the slot and communicates with the slot. The hook body is used to slide from the slot to the induction groove along the direction of being clamped into the slot when the hook structure is impacted.

[0007] Optionally, the hook body is used to be clamped on the base at a preset angle with respect to the horizontal plane, and the preset angle matches the collision angle of the head with respect to the horizontal plane.

[0008] Optionally, the base includes a base body and a locking block connected to each other. The base body and the locking block enclose the card slot. The guiding slot is provided on the base body and is located at one end where the base body is connected to the locking block. The locking hook body is inserted into the card slot from the end of the locking block far from the connection with the base body and is used to abut against the bottom of the locking block.

[0009] Optionally, the base further includes a first buffer member. The first buffer member is wrapped on the outer surface of the locking block, and the locking hook body is used to be clamped on the first buffer member.

[0010] Optionally, the card slot has a first slot wall and a second slot wall arranged oppositely. The first slot wall is located on the first buffer member, and the second slot wall is located on the base body. The locking hook body is used to abut against the first slot wall, and a groove is provided on the first slot wall. The groove extends from one end of the first slot wall to the other end along the direction in which the locking hook body is inserted into the card slot.

[0011] Optionally, the second slot wall is inclined towards the guiding slot.

[0012] Optionally, the base further includes a second buffer member. The base body includes a bottom plate, a first side plate and a second side plate. The first side plate and the second side plate are oppositely arranged on both sides of the bottom plate. The locking block is located between the first side plate and the second side plate. The second buffer member is arranged on the side surface of the first side plate facing the second side plate and / or on the side surface of the second side plate facing the first side plate.

[0013] Optionally, the mounting bracket includes a bracket body and support arms provided on both sides of the bracket body. One end of the support arm is connected to the bracket body, and the other end is used to be connected to the inner panel of the engine hood. A bending portion is provided on the support arm, and the mounting bracket is used to bend and deform at the bending portion.

[0014] To solve the above problems, the present invention further provides a vehicle including the locking hook structure as described above.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When using the hook structure of the present invention to lock the engine hood, the mounting bracket of the hook structure can be installed on the inner panel of the engine hood, the hook body can be snapped onto the mounting bracket, and the base of the hook structure can be installed on the front-end module of the vehicle to achieve the installation and fixation of the mounting bracket, the hook body and the base. The assembly process is simple and convenient. At the same time, a card slot is opened on the base. In this way, the closing of the engine hood can be achieved by snapping the hook body into the card slot. Moreover, when the position of the engine hood corresponding to the hook structure is impacted, such as a head collision, the hook body can first slide backward along the base under the action of the impact force, and then the mounting bracket can collapse along the impact direction, so that the head collapse space of the engine hood can be increased through two stages of collapse deformation, thereby reducing the injury value during the head collision and effectively improving the safety performance of the whole vehicle.

[0027] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned accompanying drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here.

[0028] Combined with Figures 1 to 3 As shown, an embodiment of the present invention provides a hook structure, which includes a mounting bracket 1, a hook body 2, and a base 3. The mounting bracket 1 is used to be mounted on the inner panel 510 of the engine hood, and the base 3 is used to be mounted on the front-end module of the vehicle. A slot 3 is provided on the base 3. One end of the hook body 2 is clamped with the mounting bracket 1, and the other end is used to be clamped with the slot 31. When the hook structure is impacted, the hook body 2 is used to slide along the base 3, and the mounting bracket 1 is used to collapse along the impact direction.

[0029] Specifically, the engine hood 500 generally includes an inner panel 510 of the engine hood and an outer panel 520 of the engine hood. The mounting bracket 1 is usually welded to the inner panel 510 of the engine hood by spot welding, and the base 3 is usually fixedly installed on the front-end module of the vehicle by fasteners such as bolts. Among them, the front-end module of the vehicle refers to the frame structure at the front end of the vehicle, which is used to integrate front-end parts such as a radiator, a condenser, an intercooler, and a bumper beam. For a fixed engine hood, usually the engine hood 500 is assembled to the vehicle to lock the hook structure to achieve the closing of the engine hood 500. Correspondingly, the engine hood 500 is disassembled as a whole to unlock the hook structure, thereby realizing the opening of the engine hood 500. When the engine hood 500 is closed, the hook structure is in a locked state. At this time, the upper end of the hook body 2 is clamped on the mounting bracket 1, and the lower end of the hook body 2 is generally inserted into the slot 31 from front to back. Specifically, it is along Figure 2The middle dashed arrow is inserted into the card slot 31 in the direction, so as to be clamped with the base 3 at the card slot 31; when the engine hood 500 is opened, the hook structure is in the unlocked state. At this time, the upper end of the hook body 2 is still clamped on the mounting bracket 1, and the lower end of the hook body 2 disengages from the card slot 31, so that the hook body 2 is separated from the base 3. When the position of the engine hood 500 corresponding to the hook structure is impacted, such as a head collision, the hook body 2 slides backward along the base 3 under the action of the impact force. This is the first-stage collapse deformation. Then, the mounting bracket 1 begins to collapse along the impact direction. This is the second-stage collapse deformation.

[0030] In this embodiment, when using the hook structure to lock the engine hood 500, the mounting bracket 1 of the hook structure can be installed on the inner panel 510 of the engine hood, the hook body 2 can be clamped to the mounting bracket 1, and the base 3 of the hook structure can be installed on the front-end module of the vehicle to realize the installation and fixation of the mounting bracket 1, the hook body 2 and the base 3. The assembly process is simple and convenient. At the same time, a card slot 31 is provided on the base 3. In this way, the engine hood 500 can be closed by clamping the hook body 2 with the card slot 31. Moreover, when the position of the engine hood 500 corresponding to the hook structure is impacted, such as a head collision, the hook body 2 can first slide backward along the base 3 under the action of the impact force, and then the mounting bracket 1 collapses along the impact direction. Thus, the head collapse space of the engine hood 500 can be increased through two stages of collapse deformation, and further, the injury value during the head collision can be reduced, effectively improving the safety performance of the whole vehicle.

[0031] Optionally, as shown in Figure 2 the base 3 is further provided with an induction groove 32. The induction groove 32 is located below the card slot 31 and communicates with the card slot 31. The hook body 2 is used to slide from the card slot 31 to the induction groove 32 along the direction of being inserted into the card slot 31 when the hook structure is impacted.

[0032] Specifically, when assembling the locking hook structure onto the engine hood 500, the guiding groove 32 on the base 3 is located below and behind the clamping groove 31, that is, the guiding groove 32 is located at the lower rear of the clamping groove 31. In other words, there is a height difference between the clamping groove 31 and the guiding groove 32 in the vertical direction. During the first-stage collapse deformation process, the height difference between the clamping groove 31 and the guiding groove 32 in the vertical direction constitutes the collapse space in the first stage. During the second-stage collapse deformation process, the deformation amount of the mounting bracket 1 in the impact direction constitutes the collapse space in the second stage. Through the collapse deformation in two stages, the head collapse space of the engine hood 500 is effectively increased. For example, for a traditional openable engine hood, the pedestrian protection usually requires the head collapse space of the engine hood 500 to be 55 mm. In this embodiment, through the deformation in two stages, the head collapse space of the engine hood 500 can be increased from the original 55 mm to 75 mm, meeting the head collapse space requirements of a fixed engine hood.

[0033] In this embodiment, by opening a guiding groove 32 communicating with the clamping groove 31 on the base 3 and making the guiding groove 32 located below the clamping groove 31, when the position of the engine hood 500 corresponding to the locking hook structure is impacted, such as by a head collision, the locking hook body 2 first slides backward along the clamping groove 31 under the action of the impact force, and then slides downward to the bottom of the guiding groove 32 at the guiding groove 32. This not only makes the movement trajectory of the locking hook body 2 controllable, but also increases the collapse space in the first stage, thereby further increasing the head collapse space of the engine hood 500, ensuring that when the locking hook structure is applied to a fixed engine hood, the head collapse space of the engine hood 500 can still meet the requirements.

[0034] Optionally, as shown in Figure 1 the locking hook body 2 is used to be clamped on the base 3 at a preset angle with respect to the horizontal plane, and the preset angle matches the collision angle of the head with respect to the horizontal plane.

[0035] It should be noted that Figure 1 the dashed circle in Figure 1 represents the head, Figure 1 the arrow in Figure 6 represents the head collision direction,

[0036] In this embodiment, when the hook body 2 is clamped to the base 3 at a preset angle, the upper end of the hook body 2 is located in front of the lower end, so that the hook body 2 is clamped to the base 3 in an inclined state, and the preset angle is the same as or approximately the same as the head collision angle α, that is, the preset angle is slightly less than or equal to or slightly greater than the head collision angle α. For example, the head collision angle α is usually 50°, so the inclination angle of the hook body 2 can be set to 49° or 50° or 51°. In this way, it can be ensured that the impact force generated by the head collision can be transmitted to the hook body 2 parallel to the plane where the hook body 2 is located, ensuring that the hook body 2 can smoothly slide backward into the induction groove 32.

[0037] Optionally, as shown in combination with Figure 2 and Figure 3 The base 3 includes a base body 33 and a locking block 34 connected to each other. The base body 33 and the locking block 34 enclose a clamping groove 31. The induction groove 32 is provided on the base body 33 and is located at one end where the base body 33 is connected to the locking block 34. The hook body 2 is inserted into the clamping groove 31 from the end of the locking block 34 far from the connection with the base body 33 and is used to abut against the bottom of the locking block 34.

[0038] In this embodiment, the rear end of the locking block 34 is connected to the rear end of the base body 33. The front end of the locking block 34 is a free end, and the locking block 34 and the base body 33 enclose a clamping groove 31. The induction groove 32 is provided at the rear end of the base body 33. The hook body 2 is usually in a ring shape or a semi-surround shape. After the hook body 2 is inserted into the clamping groove 31 from front to back, the hook body 2 is sleeved on the locking block 34, and the inner side of the lower end of the hook body 2 abuts against the bottom of the locking block 34, so that the hook body 2 hooks the locking block 34. In this way, the clamping between the hook body 2 and the base 3 is realized, and the structure is simple and convenient for processing and manufacturing.

[0039] Optionally, as shown in combination with Figure 4 and Figure 5 The base 3 further includes a first buffer member 35. The first buffer member 35 is wrapped on the outer surface of the locking block 34, and the hook body 2 is used to be clamped on the first buffer member 35.

[0040] In this embodiment, the base body 33 and the locking block 34 are usually injection-molded parts. The first buffer member 35 is usually made of a soft rubber such as thermoplastic vulcanizate (abbreviation: TPV). The first buffer member 35 can be wrapped on the outer surface of the locking block 34 by means of bonding or clamping, so that the hook body 2 is clamped on the first buffer member 35 when the hook body 2 is clamped to the base. In this way, it can be avoided that the hook body 2 causes wear to the locking block 34 when sliding. At the same time, the first buffer member 35 can also buffer the vibration during the vehicle driving process, thereby improving the NVH (i.e., the English abbreviation of noise, vibration and harshness) performance of the engine hood 500.

[0041] Optionally, as shown in combination withFigure 2 and Figure 5 As shown in Figure 5 , the card slot 31 has a first slot wall 311 and a second slot wall 312 which are oppositely arranged. The first slot wall 311 is located on the first buffer member 35, and the second slot wall 312 is located on the base body 33. The hook body 2 is used to abut against the first slot wall 311, and a groove 3112 is provided on the first slot wall 311. The groove 3112 extends from one end of the first slot wall 311 to the other end along the direction in which the hook body 2 is inserted into the card slot 31.

[0042] Specifically, the groove 3112 is recessed upward from the first slot wall 311. In practical applications, multiple grooves 3112 are usually provided. The multiple grooves 3112 are arranged at equal intervals on the first slot wall 311, and the groove 3112 extends from the front end to the rear end of the first slot wall 311.

[0043] In this way, a lubricating medium such as lubricating oil can be applied in the groove 3112 to reduce the frictional force between the hook body 2 and the first buffer member 35, so that the hook body 2 can smoothly slide along the card slot 31 to the bottom of the induction groove 32 when receiving an impact force from front to back.

[0044] Optionally, as shown in Figure 2 Figure 2 , the second slot wall 312 is used to abut against the hook body 2.

[0045] Specifically, when the hook body 2 is clamped on the base 3, if there is a gap between the second slot wall 312 and the hook body 2, when the hook body 2 receives the impact force caused by a head collision, it is easy to first collide downward with the second slot wall 312 on the base body 33 and then slide backward to the bottom of the induction groove 32. When the hook body 2 collides downward with the second slot wall 312, a relatively large reaction force is easily generated and applied to the head, increasing the head injury value.

[0046] Therefore, in this embodiment, the second slot wall 312 is set to be used to abut against the hook body 2 to prevent the hook body 2 from colliding with the second slot wall 312 when the hook structure is subjected to a collision impact, thereby further reducing the injury value during the head collision and further improving the safety performance of the whole vehicle. Moreover, when the hook structure is locked, the hook body 2 is clamped on the lock block 34 and also supported on the base body 33, which can not only play a Z-direction fixing role during the assembly process of the engine hood 500, but also enable the hook body 2 to provide a supporting force for the engine hood 500 in the Z direction (i.e., the up and down direction), thereby improving the anti-denting performance and NVH performance of the engine hood 500 at the hook structure.

[0047] Optionally, as shown in Figure 2 Figure 2 , the second slot wall 312 is inclined toward the induction groove 32.

[0048] In this embodiment, since the induction groove 32 is located behind the clamping groove 31, the second groove wall 312 is inclined backward, that is, the second groove wall 312 is arranged in an inclined state with the front end high and the rear end low. In this way, the second groove wall 312 can guide the hook body 2 to slide backward and downward into the induction groove 32 when the hook structure is impacted, improving the smoothness of the hook body 2 sliding into the bottom of the induction groove 32.

[0049] Optionally, in combination with Figure 4 and Figure 5 As shown, the base 3 further includes a second buffer 36. The base body 33 includes a bottom plate 331, a first side plate 332 and a second side plate 333. The first side plate 332 and the second side plate 333 are oppositely arranged on both sides of the bottom plate 331. The locking block 34 is located between the first side plate 332 and the second side plate 333. The second buffer 36 is arranged on the side of the first side plate 332 facing the second side plate 333 and / or on the side of the second side plate 333 facing the first side plate 332.

[0050] Specifically, the first side plate 332 and the second side plate 333 are oppositely arranged on the left and right sides of the bottom plate 331, that is, the first side plate 332 constitutes the left side plate of the base body 33, and the second side plate 333 constitutes the right side plate of the base body 33, while the locking block 34 is located between the first side plate 332 and the second side plate 333. The material of the second buffer 36 is usually the same as that of the first buffer 35, that is, it is made of soft rubber. The second buffer 36 can be covered on the right side of the first side plate 332 and / or the left side of the second side plate 333 by means of bonding or clamping, and the second buffer 36 is arranged at an interval from the locking block 34.

[0051] In this way, by arranging the second buffer 36 on the first side plate 332 and / or the second side plate 333, the left and right side plates of the base body 33 can be prevented from being worn by the hook body 2 during the sliding process.

[0052] Optionally, in combination with Figure 4 and Figure 6 As shown, the mounting bracket 1 includes a bracket body 11 and support arms 12 arranged on both sides of the bracket body 11. One end of the support arm 12 is connected to the bracket body 11, and the other end is used to connect to the inner panel 510 of the engine hood. A bending portion 121 is provided on the support arm 12, and the mounting bracket 1 is used to bend and deform at the bending portion 121.

[0053] Specifically, a support arm 12 is provided on each of the left and right sides of the bracket body 11. One end of the support arm 12 is connected to the bracket body 11, and the other end extends upward and away from the bracket body 11. The support arm 12 is connected to the inner panel 510 of the engine hood by spot welding, so that the mounting bracket 1 is fixed to the inner panel 510 of the engine hood. Moreover, a bending portion 121 is provided on the support arm 12. For the support arm 12 provided on the left side of the bracket body 11, the bending portion 121 is formed by bending a partial position of the support arm 12 toward the right. For the support arm 12 provided on the right side of the bracket body 11, the bending portion 121 is formed by bending a partial position of the support arm 12 toward the left.

[0054] In this way, the bending portion 121 can be provided on the support arm 12 as an induction structure, so that the mounting bracket 1 can be further crushed and deformed at the bending portion 121, thereby increasing the crushing space of the mounting bracket 1 and further reducing the head injury value.

[0055] Furthermore, a weakening hole 122 is also provided on the support arm 12. With this setting, it is more convenient for the mounting bracket 1 to be further crushed and deformed.

[0056] Furthermore, the mounting bracket 1 further includes a connecting arm 13. The connecting arm 13 and the support arm 12 are respectively connected to adjacent sides on the bracket body 11, and one end of the connecting arm 13 away from the bracket body 11 is used to connect to the inner panel 510 of the engine hood. With this setting, the structural strength of the mounting bracket 1 is improved, thereby further improving the anti-denting performance of the engine hood 500 at the hook structure.

[0057] Another embodiment of the present invention provides a vehicle, including the hook structure as described above.

[0058] The beneficial effects of the vehicle in this embodiment compared with the prior art are the same as those of the above-mentioned hook structure, and will not be elaborated here.

[0059] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present invention.
