Description

Technical Field

[0001] The utility model belongs to the technical field of engine hoods, and more specifically relates to an engine hood lock installation structure and an engine hood assembly. Background Art

[0002] The hood is a body part located at the front of the car that can be opened and closed. It is used to cover the engine compartment and can also play a role in waterproofing, dustproofing and noise reduction. When the vehicle is involved in a head-on collision, the outer panel of the hood deforms toward the inner panel to absorb the impact force exerted on the hood by the pedestrian's head, thereby providing a cushion for the pedestrian's head. Therefore, during the design process of the hood, it is necessary to ensure that it has a certain degree of rigidity while also considering the safety protection of pedestrians, so as to minimize physical damage to pedestrians in the event of a collision.

[0003] The locking structure of the engine hood is used to control the opening and closing of the engine hood, including a lock buckle arranged on the engine hood and a latch arranged on the vehicle body, wherein the lock buckle is arranged on the inner panel of the engine hood, and its connection point with the inner panel of the engine hood is a rigid connection, resulting in greater strength and rigidity at the connection point. Therefore, when designing the installation structure of the lock buckle, the impact of the connection point of the lock buckle on the pedestrian's head in a frontal collision accident of the vehicle should be considered to reduce the damage to the pedestrian caused by the lock buckle connection point. In addition, the existing engine hood lock installation structure has a low degree of fit with the inner panel of the engine hood, a small contact surface, and poor stability, which easily causes abnormal noise when the engine hood is opened and closed, greatly reducing the user's comfort.

[0027] Please also read Figures 1 to 3The engine hood lock installation structure and the engine hood assembly provided by the utility model are now described. The engine hood lock installation structure includes a mounting member 6 and a support frame 5. The mounting member 6 is arranged on the outer side of the inner panel 1. The mounting member 6 has a lock buckle installation position, and the lock buckle installation position is used to install the lock buckle 4; the support frame 5 is arranged between the inner panel 1 and the outer panel 2, and is respectively connected to the inner panel 1 and the outer panel 2. The support frame 5 forms a force transmission structure between the inner panel 1 and the outer panel 2.

[0028] Compared with the prior art, the hood lock installation structure provided by the utility model is arranged between the inner panel 1 and the outer panel 2, the mounting member 6 is connected to the outer side of the inner panel 1, and the lock 4 is installed on the inner side of the inner panel 1 and is arranged corresponding to the mounting member 6. The mounting member 6 can increase the strength and rigidity of the inner panel 1 and the lock installation position, provide effective support for the lock 4, and avoid vibration force generated when the hood is closed, resulting in deformation of the inner panel 1. Since the support frame 5 is respectively connected to the mounting member 6 and the outer panel 2, the support frame 5 forms a force transmission structure between the inner panel 1 and the outer panel 2. After the inner panel 1 is subjected to force, the force is transmitted to the outer panel 2 through the support frame 5, reducing the vibration force generated by the hood closing and the wind noise, and improving the NVH performance of the vehicle. In addition, after the vehicle has a frontal collision, the force point is not only diffused around along the plate surface of the outer panel 2, but also the force is transmitted to the inner panel 1 through the support frame 5, which accelerates the diffusion of external force, avoids stress concentration at the force point, and reduces damage to personnel.

[0029] In some embodiments, see Figure 3 The support frame 5 includes a fixing plate 501 and a plurality of legs 502 connected to the fixing plate 501. The plurality of legs 502 are spaced apart along the extension direction of the fixing plate 501. The legs 502 have a fixing sheet 5022 that fits the mounting member 6 and a supporting sheet 5021 that is connected to the fixing sheet 5022 at an angle. The fixing plate 501 forms a second fixing portion, the supporting sheet 5021 forms a supporting portion, and the fixing sheet 5022 forms a first fixing portion.

[0030] The fixing plate 501 increases the contact area with the outer plate 2 and reduces the local pressure. The mounting member 6 is provided on the outer side of the inner plate 1, which not only ensures the strength of the connection with the lock buckle 4, but also avoids excessive local pressure caused by small area contact. Multiple legs 502 are connected to the fixing plate 501 at intervals along the extension direction of the fixing plate 501, reducing the contact area with the mounting member 6 and avoiding excessive local strength of the inner plate 1. In addition, the provision of multiple legs 502 can ensure uniform strength of the fixing plate 501.

[0031] Optionally, the fixing plate 501 and the fixing sheet 5022 are respectively located on opposite sides of the surface of the support sheet 5021, so that the fixing plate 501, the support sheet 5021 and the fixing sheet 5022 form a "Z"-shaped structure. Compared with the design of the "U"-shaped structure, the solution in this embodiment makes the forces on both sides of the support sheet 5021 more uniform, thereby preventing the support legs 502 from breaking due to vibration when the engine hood is closed.

[0032] In some embodiments, see Figures 2 to 3 The mounting member 6 includes a mounting plate 601 and a reinforcing flange 602 connected to the outer edge of the mounting plate 601 . The mounting plate 601 is connected to the inner plate 1 , and the reinforcing flange 602 is bent toward the outer side of the mounting plate 601 .

[0033] In this embodiment, the mounting plate 601 is attached to the inner plate 1, increasing the contact area with the inner plate 1, providing effective support for the lock 4, and preventing the connection between the inner plate 1 and the lock 4 from being deformed or damaged due to insufficient strength. The design of the reinforced flange 602 increases the strength of the inner plate 1, and is bent toward the outside of the mounting plate 601 to avoid interference with the inner plate 1.

[0034] Optionally, the inner side of the mounting plate 601 has a clearance groove, which protrudes outward from the side of the inner plate 1. The clearance groove increases the strength of the mounting plate 601 on the one hand, and forms a vibration-damping space between the clearance groove and the inner plate 1 on the other hand, thereby reducing the vibration of the mounting plate 601 caused by the shaking of the lock buckle 4 and reducing noise.

[0035] In some embodiments, see Figure 3 The mounting member 6 is provided with a drainage hole 604 and a mounting hole 603 . The mounting hole 603 corresponds to the avoidance hole provided in the inner plate 1 . The mounting hole 603 forms a lock mounting position.

[0036] After the locking member passes through the avoidance and the mounting hole 603, the lock buckle 4 is installed on the inner side of the inner plate 1. The drainage hole 604 can drain the liquid between the inner plate 1 and the mounting member 6 to prevent the mounting member 6 and the inner plate 1 from being corroded due to excessive humidity between the inner plate 1 and the mounting member 6, and the drainage hole 604 can also reduce the weight of the mounting member 6.

[0037] In some embodiments, see Figures 1 to 3 The fixing plate 501 and the fixing sheet 5022 are both arranged non-perpendicularly to the supporting sheet 5021 .

[0038] The fixing plate 501 and the fixing sheet 5022 can be set at an acute angle or an obtuse angle with the supporting sheet 5021, and adopt a non-vertical setting method. The supporting force of the supporting sheet 5021 on the outer panel 2 is limited. When the vehicle collides head-on, pedestrians touching the engine hood are prone to collapse and energy absorption, meeting safety requirements.

[0039] In some embodiments, see Figure 3The support sheet 5021 is provided with a collapse hole 5023 .

[0040] The design of the collapse hole 5023 reduces the support strength of the support sheet 5021, realizes collapse energy absorption when a frontal collision occurs, reduces the damage to pedestrians, improves safety, and at the same time, can also reduce the weight of the support frame 5.

[0041] Optionally, the collapse hole 5023 is a strip-shaped hole, and extends along the extension direction of the support portion.

[0042] In some embodiments, see Figure 3 The fixing plate 5022 is provided with a receiving groove 5011, and the receiving groove 5011 is used for filling the expansion glue.

[0043] The fixing plate 5022 is connected to the outer panel 2 by means of expansion glue, which can not only reduce vibration but also ensure the anti-dent rigidity of the outer panel 2 and improve the torsional rigidity of the engine hood.

[0044] Based on the same inventive concept, the utility model also provides an engine hood assembly. Figure 1 The engine hood assembly includes any one of the above-mentioned engine hood lock mounting structures, and also includes an inner plate 1 connected to the mounting member 6 and an outer plate 2 connected to the second fixing portion.

[0045] The hood assembly provided by the utility model adopts the above-mentioned hood lock installation structure, which is arranged between the inner panel 1 and the outer panel 2, the mounting member 6 is connected to the outer side of the inner panel 1, and the lock 4 is installed on the inner side of the inner panel 1 and arranged corresponding to the mounting member 6. The mounting member 6 can increase the strength and rigidity of the inner panel 1 and the lock installation position, provide effective support for the lock 4, and avoid vibration force generated when the hood is closed, causing deformation of the inner panel 1. Since the support frame 5 is respectively connected to the mounting member 6 and the outer panel 2, the support frame 5 forms a force transmission structure between the inner panel 1 and the outer panel 2. After the inner panel 1 is subjected to force, the force is transmitted to the outer panel 2 through the support frame 5, reducing the vibration force generated by the hood closing and the wind noise, and improving the NVH performance of the vehicle. In addition, after the vehicle has a frontal collision, the force point is not only diffused around along the plate surface of the outer panel 2, but also the force is transmitted to the inner panel 1 through the support frame 5, which accelerates the diffusion of external force, avoids stress concentration at the force point, and reduces damage to personnel.

[0046] In some embodiments, see Figure 1 The inner panel 1 has a weight reduction area, in which a plurality of independent weight reduction holes 103 are provided, and the engine hood lock mounting structure is located outside the weight reduction area.

[0047] The weight-reducing holes 103 can reduce the strength of the inner panel 1, effectively protecting the safety of pedestrians in the event of a frontal collision; at the same time, the design of the weight-reducing area also increases the storage space in the corresponding engine compartment. Multiple weight-reducing holes 103 are designed independently of each other to avoid deformation of the inner panel 1 due to excessive weight-reducing holes 103.

[0048] In some embodiments, see Figure 1 The inner surface of the inner plate 1 has a groove 102, the groove 102 forms a weight reduction area, a step 101 is arranged inside the groove 102, the step 101 is arranged outside the plurality of weight reduction holes 103, and an avoidance area 1021 is provided at the edge of the groove 102 and the position corresponding to the lock buckle 4.

[0049] The solution in this embodiment can increase the storage space in the engine compartment, and the design of the avoidance area 1021 avoids the interference between the edge of the groove 102 and the lock buckle 4. The design structure of the step 101 is smooth and smooth, which is conducive to stamping, reduces the risk of cracking and wrinkling during the stamping process, and improves product precision.

[0050] Optionally, the shape of the avoidance area 1021 is consistent with the properties of the mounting plate 601 of the lock buckle 4, which can effectively avoid the mounting plate 601 of the lock buckle 4 and prevent the avoidance area 1021 from being too large.

[0051] Optionally, the hood lock installation structure further includes a buffer block 3 inserted into the inner panel 1, the buffer block 3 is located outside the lock buckle 4, and the support portion is parallel to the longitudinal surface of the step 101. The buffer block 3 can alleviate the vibration force between the inner panel 1 and the vehicle body when the hood is closed, and the support portion is parallel to the longitudinal surface of the step 101, which can increase the force transmission channel of the vibration force. It also reduces the vibration caused by closing the hood and improves the NVH performance.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
