Description

Technical Field

[0001] The present invention relates to the technical field of vehicle structures, and in particular to an engine hood lock installation structure. The present invention also relates to a vehicle using the engine hood lock installation structure. Background Art

[0002] The vehicle's engine hood needs to be locked using a hood lock. The hood lock mounting structure is generally located on the upper part of the front end frame at the leading edge of the hood to provide installation support for the hood lock body. Most of them use a hood lock support reinforcement between the upper part of the front end frame and the front collision beam assembly to meet the stiffness requirements when the hood is closed and impacted.

[0003] At present, the engine hood lock installation structure is composed of the main structures such as the front upper crossbeam, the front lower crossbeam upper plate, the front lower crossbeam lower plate, the front left connecting beam, and the front right connecting beam. The hood lock support reinforcement is directly fixed to the front side of the front upper crossbeam for installing the hood lock body. The disadvantage of this structure is that the impact force of the engine hood directly acts on the installation surface of the front upper crossbeam. At the moment of closing the engine hood, it is easy to cause a large displacement deformation of the hood lock support reinforcement. The hood lock installation structure is not rigid enough and is prone to shaking, which affects the opening and closing quality of the engine hood. Summary of the invention

[0004] In view of this, the present invention aims to provide a hood lock installation structure to improve the strength and rigidity of the hood lock installation position and solve the problem of the hood assembly shaking when closing.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0022] Furthermore, it also includes a middle connecting beam extending in the up-down direction of the vehicle, and the middle connecting beam is connected between the reinforcing bracket and the upper cross beam of the cabin.

[0054] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0055] The present embodiment relates to a hood lock mounting structure, which includes a hood lock mounting bracket 2 and a reinforcement bracket 3 provided on a cabin upper cross beam 1 at the front end of a vehicle body. The cabin upper cross beam 1 is provided with a through portion 103 for the engine hood lock 6 to pass through, and the hood lock mounting bracket 2 is connected to the rear side of the cabin upper cross beam 1 corresponding to the through portion 103.

[0056] The reinforcing bracket 3 is connected to the front side of the cabin upper cross beam 1 corresponding to the through portion 103, and the hood lock mounting bracket 2, the reinforcing bracket 3 and the cabin upper cross beam 1 form a ring-shaped installation space, and the engine hood lock 6 is located in the installation space.

[0057] The engine hood lock mounting structure of the present embodiment can form an annular hood lock mounting space between the hood lock mounting bracket 2, the reinforcing bracket 3 and the front end upper cross beam by providing a hood lock mounting bracket 2 and a reinforcing bracket 3, so that the annular connecting structure at the installation position of the engine hood lock 6 can cooperate in bearing the load, so as to improve the installation strength and rigidity of the engine hood lock 6 and solve the shaking problem when the hood assembly is closed.

[0058] Based on the above overall introduction, an exemplary structure of the engine hood lock installation structure of this embodiment is as follows: Figure 1 to Figure 2 As shown, the cabin upper cross beam 1 is a part of the automobile frame, which is arranged along the width direction of the vehicle body, i.e., the Y direction. Figure 2 As shown, the hood lock mounting bracket 2 is connected to the middle of the cabin upper cross beam 1 and corresponds to the position of the through portion 103 , so that the engine hood lock 6 can be installed on the hood lock mounting bracket 2 .

[0059] As a feasible implementation, the cabin upper cross beam 1 of this embodiment has a transverse side wall 101 and a longitudinal side wall 102 which are perpendicular to each other. The through portion 103 includes a connected transverse portion and a longitudinal portion, the transverse portion is arranged on the transverse side wall 101, and the longitudinal portion is arranged on the longitudinal side wall 102. In terms of specific structure, Figure 3 and Figure 4 As shown, the through portion 103 is a through hole, and the edge of the through hole is irregularly shaped, and the longitudinal side wall 102 is arranged along the vehicle body height direction, i.e., the Z direction, and the transverse side wall 101 is arranged along the vehicle body front and rear direction, i.e., the X direction. Such an arrangement can improve the structural strength and rigidity of the cabin upper cross beam 1 itself.

[0060] In order to further improve the structural strength of the cabin upper cross beam 1, in this embodiment, longitudinal side walls 102 are provided on both the front and rear sides of the transverse side wall 101. Figure 4 and Figure 5 As shown, the two sides of the transverse side wall 101 are connected by the longitudinal side wall 102 extending toward the bottom of the vehicle body, and the extension length of the longitudinal side wall 102 on the front side is greater than that of the longitudinal side wall 102 on the rear side. Figure 5 As shown, the longitudinal end surface of the upper cross beam 1 of the cabin forms an inwardly concave stepped end surface structure, which can improve the bearing capacity of the upper cross beam 1 of the cabin in the X direction and the Z direction.

[0061] In addition, a protruding portion 1021 protruding toward the front of the vehicle is provided on the front longitudinal side wall 102, and the longitudinal portion is provided on the protruding portion 1021. A plurality of first step portions 1022 arranged in sequence along the left and right directions of the vehicle are provided on the longitudinal side walls 102 on the left and right sides of the protruding portion 1021. Figure 4 As shown, the protrusion 1021 is arranged in the middle of the front longitudinal side wall 102, and protrudes toward the front side of the vehicle body compared to the longitudinal side walls 102 on both sides, thereby improving the structural strength of the cabin upper cross beam 1 in the front and rear direction of the vehicle body, that is, the X direction.

[0062] Still Figure 4 As shown, the longitudinal side wall 102 located on both sides of the protruding portion 1021 is formed with a plurality of first step portions 1022. In this embodiment, three first step portions 1022 are arranged sequentially from the protruding portion 1021 to the rear of the vehicle body, and are arranged sequentially along the width direction of the vehicle body. In addition, in the width direction of the vehicle body, the first step portions 1022 on both sides of the protruding portion 1021 are arranged symmetrically. Such an arrangement can improve the structural strength of the cabin upper cross beam 1 along the X direction of the vehicle body.

[0063] As another preferred embodiment, the lateral side wall 101 of this embodiment is provided with a plurality of second step portions 1011 arranged along the front-rear direction of the vehicle. Figure 4 As shown, the second step portion 1011 is a plurality of protrusions formed on the transverse side wall 101, and the protrusion surface on the transverse side wall 101 is the highest at a position corresponding to the through portion 103. Such a configuration not only facilitates the connection of the cover lock mounting bracket 2, but also improves the structural strength of the cabin upper cross beam 1 along the vehicle body height direction, i.e., the Z direction.

[0064] It should be noted that, as described above, the longitudinal side walls 102 are arranged on both the front and rear sides of the transverse side walls 101, so that the cabin upper cross beam 1 can be made into a concave cross-section structure, so as to improve the structural rigidity of the cabin upper cross beam 1 in the X and Z directions. The first step portion 1022 and the second step portion 1011 are also arranged to improve the structural rigidity of the cabin upper cross beam 1 along the X and Y directions of the vehicle body, so that the cabin upper cross beam 1 as a whole has good structural strength and rigidity in three-dimensional space, thereby greatly improving the installation strength of the engine hood lock 6 and preventing the deformation of the hood lock mounting bracket 2 under the vibration when buckled and closed.

[0065] Furthermore, in a specific implementation, it is preferred to provide both the first step portion 1022 on the longitudinal side wall 102 and the second step portion 1011 on the transverse side wall 101 . Of course, only the first step portion 1022 or only the second step portion 1011 may also be provided.

[0066] As a preferred embodiment, the hood lock mounting bracket 2 includes a first portion 201 and a second portion 202 that are perpendicular to each other, the first portion 201 is arranged along the up-down direction of the vehicle, and the second portion 202 is arranged along the front-back direction of the vehicle. Figure 6 and Figure 7 As shown, the cover lock mounting bracket 2 is a sheet metal component, and as mentioned above, is mainly composed of a first part 201 and a second part 202. Fig. 9 As shown, when the cover lock mounting bracket 2 is installed at the through portion 103 of the cabin upper cross beam 1, the first portion 201 is arranged along the Z direction of the vehicle body, and the second portion 202 extends along the X direction of the vehicle body and toward the front of the vehicle.

[0067] like Figure 6 and Figure 7 As shown, in order to improve the installation firmness of the hood lock mounting bracket 2, both left and right ends of the first part 201 are bent toward the front of the vehicle so as to be able to abut and connect with the lateral side wall 101 of the cabin upper cross beam 1. In addition, such an arrangement can also further increase the structural strength of the hood lock mounting bracket 2 itself, which is conducive to improving the installation stability of the engine hood lock 6.

[0068] like Fig. 9 As shown, the first part 201 is provided with a mounting portion 2011 for mounting the engine hood lock 6. At the same time, the first part 201 is provided with an "M"-shaped reinforcing rib 2012, and the bottom of the reinforcing rib 2012 extends to the second part 202. The mounting portion 2011 in this embodiment is a circular through hole formed on the hood lock mounting frame, as shown in FIG. Figure 2 and Figure 8 As shown, the engine hood lock 6 abuts against the first portion 201 , and the engine hood lock 6 is fixedly connected to the hood lock mounting bracket 2 by bolts.

[0069] In addition, by providing an "M"-shaped reinforcing rib 2012 and extending it from the first part 201 to the second part 202, that is, the reinforcing rib 2012 extends from the mounting surface of the engine hood lock 6 to the X-direction load-bearing surface, not only the overall structural strength of the hood lock mounting bracket 2 is improved, but also the rigidity of the mounting surface and the load-bearing surface of the engine hood lock 6 is effectively improved, thereby ensuring the installation effect of the hood lock and avoiding shaking when the engine cover is closed.

[0070] Furthermore, a first flange 203 is provided on the top of the first portion 201 and is folded outward from the installation space. Figure 6 , Figure 7 , Fig. 9 As shown, the first flange 203 is connected to the first part 201 and is vertically arranged. The first flange 203 is arranged at the lower end of the transverse side wall 101, and the arrangement of the first flange 203 is arranged in accordance with the second step portion 1011, which can facilitate the positioning of the cover lock mounting bracket 2 when connected to the cabin upper cross beam 1. In addition, the arrangement of the first flange 203 also improves the structural strength of the cover lock mounting bracket 2 in the upper and lower directions of the vehicle body.

[0071] Preferably, a first through hole 2013 is provided in the middle of the first part 201 in the left-right direction of the embodiment, the first through hole 2013 extends from the first part 201 to the first flange 203, and the first flange 203 is connected to the upper cross beam 1 of the cabin in the vertical direction of the vehicle. Figure 6 and Figure 7As shown, the first through hole 2013 of this embodiment is provided as a long slot hole and is formed at the connection between the first part 201 and the first flange 203. By providing the first through hole 2013, it is not only convenient to install the engine hood lock in the installation space, but also possible to absorb the vibration energy on both sides during the engagement of the engine hood lock, avoiding the resonance reaction formed by the superposition of the vibrations on both sides along the middle.

[0072] As a further embodiment, the left and right sides of the first part 201 are respectively provided with second flanges 204 folded outwards of the installation space. The second flanges 204 are connected to the upper cross beam 1 of the cabin in the front-rear direction of the vehicle. Figure 6 , Figure 7 , Fig. 9 As shown, the second flange 204 extends from the first portion 201 toward the front side of the vehicle body and is connected to the protruding portion 1021 of the cabin upper cross beam 1 .

[0073] like Figure 6 and Figure 7 As shown, the second flange 204 is connected to the first flange 203. The second flange 204 abuts against the inner side of the protruding portion 1021. The first flange 203 and the second flange 204 are both provided with circular through holes for installation, and the cover lock mounting bracket 2 can be fixedly connected to the upper cross beam 1 of the cabin by bolts and nuts.

[0074] And, still Figure 6 and Figure 7 As shown, the arrangement of the first flange 203 and the second flange 204 enables the peripheries of the first part 201 and the second part 202 to abut against the upper cross beam 1 of the cabin, which can ensure that the hood lock mounting bracket 2 will not rotate after being fixed to the upper cross beam 1 of the cabin, thereby ensuring the installation stability of the engine hood.

[0075] like Fig.10 As shown, they are respectively connected to the lower end of the through portion 103, and are used to buckle the cover lock mounting bracket 2 on the through portion 103 of the cabin upper cross beam 1, and the cover lock mounting bracket 2 and the cabin upper cross beam 1 surround a semi-box space that is open upward. In this way, the X-direction and Z-direction bearing surfaces can be distributed along the periphery of the cover lock mounting bracket 2, and form a closed box with the through portion 103 of the cabin upper cross beam 1 at its front end, which not only improves the installation strength of the cover lock mounting bracket 2, but also effectively reduces the shaking caused by the impact of the lock body during the closing process of the cover.

[0076] As a preferred embodiment, the reinforcement bracket 3 of this embodiment is provided with a bulging portion 301 bulging toward the front of the vehicle. The reinforcement bracket 3 is connected to the upper cross beam 1 of the engine compartment in the vertical direction of the vehicle and / or the front-rear direction of the vehicle. Fig.11 and Fig.12 As shown, the reinforcing bracket 3 is in an inverted "U" shape, and the bulging portion 301 includes a protruding surface and two inclined surfaces 302 connected on both sides of the protruding surface.

[0077] Still Fig.11 and Fig.12 As shown, mounting parts for connecting to the upper cross beam 1 of the cabin are connected on both sides of the bulging part 301 , and the mounting parts include a longitudinal mounting part 303 connected to the inclined surface 302 of the bulging part 301 , and a transverse mounting part 304 connected above the longitudinal mounting part 303 .

[0078] Furthermore, the transverse mounting portion 304 abuts against the transverse side wall 101, and a circular through hole is provided on the transverse mounting portion 304. Correspondingly, the longitudinal mounting portion 303 abuts against the longitudinal side wall 102 close to the front end of the vehicle body, and a circular through hole is also provided on the longitudinal mounting portion 303, and the mounting bracket is fixedly connected to the upper cross beam 1 of the cabin by bolts and nuts.

[0079] It should be pointed out that the mounting hole of the reinforcing bracket 3 in this embodiment corresponds to the mounting hole on the cover lock mounting bracket 2, and a corresponding circular through hole is also provided on the cabin upper cross beam 1, and the three are penetrated by bolts and fastened with nuts. In this way, multiple parts are assembled together, avoiding the problem of increased weight of parts caused by assembly and subassembly, and facilitating the lightweight assembly process.

[0080] As Figure 2 and Fig. 9 As shown, the reinforcing bracket 3 of this embodiment, the cover lock mounting bracket 2, and the upper cross beam 1 of the cabin form a polygonal box structure, which on the one hand increases the installation and maintenance space of the cover lock, and on the other hand can improve the structural strength of the through portion 103 of the upper cross beam 1 of the cabin, further ensuring the strength requirements when the lock body is engaged.

[0081] In addition, at least one of the left and right sides of the bulging portion 301 is provided with a second through hole 3011. Fig.11 and Fig.12 As shown, the second through hole 3011 is a long hole along the extension direction of the inclined surface 302. In this embodiment, both inclined surfaces 302 are provided with the second through hole 3011. By providing the second through hole 3011, the structure of at least one side of the bulging portion 301 can be weakened to a certain extent, so as to increase the vibration amplitude at the weakened area when the excitation reaches the weakened area, thereby releasing the vibration energy and playing a vibration absorption role.

[0082] In addition, the engine hood lock installation structure of this embodiment further includes a middle connecting beam 4 extending in the vertical direction of the vehicle, and the middle connecting beam 4 is connected between the reinforcing bracket 3 and the upper cross beam 1 of the engine compartment. Figures 1 to 3 As shown, a cabin lower cross beam 5 is provided below the cabin upper cross beam 1 , and a middle connecting beam 4 is arranged along the Z direction, with its upper end fixedly connected to the bulging portion 301 of the reinforcing bracket 3 , and its lower end fixedly connected to the cabin lower cross beam 5 with bolts.

[0083] like Figure 1 As shown, in this embodiment, the reinforcing bracket 3 is welded and fixed to the middle connecting beam 4, and then bolted to the cabin upper cross beam 1 and the cabin lower cross beam 5. Such a setting can reduce the arrangement of connecting parts, further meet the lightweight requirements, reduce assembly steps, and improve assembly efficiency.

[0084] By connecting the reinforcing bracket 3 with the middle connecting beam 4 and the upper cross beam 1 of the cabin, the load-bearing force of the upper cross beam 1 of the cabin and the hood lock mounting bracket 2 is transmitted along the Z direction of the vehicle body, which can effectively reduce the impact and shaking of the lock body during the closing process of the hood, and transmit the shaking or vibration to the bottom of the vehicle body, thereby improving the closing quality of the hood.

[0085] Based on the same design concept, the present embodiment also relates to a vehicle, on which the engine hood lock mounting structure as described above is provided.

[0086] The vehicle described in this embodiment, by being provided with the engine hood lock installation structure as described above, can improve the strength of the vehicle's cabin upper cross beam 1, enhance the structural strength and rigidity of the front of the vehicle, and also ensure the stability of the engine hood lock 6 installation point, thereby improving the performance of the entire vehicle.

[0087] 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, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
