Description

Technical Field

[0001] This utility model relates to the field of vehicle processing technology, and in particular to a hood locking device. Background Technology

[0002] The hood lock is installed on the front module frame of the car and works with the latch on the hood to lock it in place. The assembly precision of the hood lock determines whether the hood can close accurately. In other words, if the installation precision of the hood lock does not meet the specified installation standards, it can easily lead to poor engagement between the hood lock and the latch, or even prevent the hood lock and latch from engaging at all.

[0003] Specifically, to facilitate the installation of the hood lock, the size of the mounting holes on the front-end module frame is usually slightly larger than the size of the mounting bolts. Therefore, if the mounting bolts are not fully secured, they have a certain range of movement within the mounting holes, preventing the hood lock from being installed correctly in one go. Typically, when installing the hood lock, technicians need to adjust the relative positions of the mounting bolts and mounting holes multiple times to ensure proper functioning during hood opening and closing and that the clearance surface difference meets requirements, leading to low production efficiency. Furthermore, due to limitations in the precision of the front-end module frame itself and the skill level of the employees, misalignment between the hood lock and the lock hook is prone to occur, resulting in poor assembly consistency. During the assembly of the mounting bolts, the high speed of the electric wrench may cause the hood lock to shift, further increasing the assembly difficulty. Utility Model Content

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] An embodiment of this utility model provides a hood locking device for assisting in the positioning of the hood lock 20 when it is installed on the front module frame 10 of a vehicle. (See reference) Figures 1-9 As shown, a first limiting part 101 is formed on the front module frame 10. The hood locking device includes a base 1, a first positioning mechanism 2, and a second positioning mechanism 3. The first positioning mechanism 2 and the second positioning mechanism 3 are both set on the base 1 and integrated with the base 1. The first positioning mechanism 2 includes a first limiting member 21 and a first clamping member 22. The second positioning mechanism 3 includes a second limiting member 31 and a second clamping member 32. The first limiting member 21 can cooperate with the first limiting part 101 for limiting. The first clamping member 22 is used to fix the hood locking device on the front module frame 10 to prevent the hood locking device from detaching from the front module frame 10. The second limiting member 31 is provided with a contour groove, and the hood lock 20 can be limited in the contour groove. The second clamping member 32 cooperates with the second limiting member 31 to clamp and fix the hood lock 20.

[0036] The aforementioned hood locking device uses a first limiting member 21, which cooperates with the first limiting part 101, to limit the hood locking device to the front module frame 10. Then, the first clamping member 22 is used to fix the hood locking device to the front module frame 10, thus determining the position of the hood locking device and the front module frame 10. Then, the second clamping member 32, in cooperation with the second limiting member 31, is used to position the hood lock 20 in all directions, thus fixing the hood lock 20 to the hood locking device. This determines the position of the hood lock 20 and the hood locking device, and the hood lock 20 is indirectly limited to the front module frame 10. When the hood lock 20 is fixed to the front module frame 10 with mounting bolts, the position of the hood lock 20 relative to the front module frame 10 is fixed, eliminating the need for manual adjustment and positioning of the hood lock 20. This ensures the accuracy and reliability of the installation position and angle of the hood lock 20, improves assembly efficiency, reduces assembly difficulty, and ensures high assembly consistency.

[0037] refer to Figure 8 As shown, in this embodiment, the first limiting part 101 includes an insertion hole on the front module frame 10, and the first limiting member 21 includes a pin that can be inserted into the insertion hole to limit the distance between the hood locking device and the front module frame 10. Specifically, the pin is L-shaped, with its first end detachably connected to the base 1 by means including but not limited to bolts, and the other end inserted into the insertion hole until the first end of the pin abuts against the front module frame 10 to achieve the limiting.

[0038] It is understood that the first limiting part 101 and the first limiting member 21 are not limited to these. In other embodiments, the first limiting part 101 may be a pin, and the first limiting member 21 may be a limiting structure with a hole or slot, wherein the first limiting part 101 can be inserted into the first limiting member 21 to limit the hood locking device and the front module frame 10. Alternatively, the first limiting part 101 and the first limiting member 21 may engage in a snap-fit ​​relationship.

[0039] refer to Figure 1 and Figure 2 As shown, the first clamping member 22 includes a fixed clamping part 221 and a movable clamping part 222. The fixed clamping part 221 is fixed on the base 1. When the first limiting member 21 is inserted and engaged with the first limiting part 101, the fixed clamping part 221 abuts against the front end module frame 10, while the movable clamping part 222 can move relative to the fixed clamping part 221 to cooperate with the fixed clamping part 221 to clamp or release the front end module frame 10.

[0040] Specifically, the fixed clamping part 221 has a clamping surface 2213, a first mounting surface 2211 and a second mounting surface 2212. The clamping surface 2213 and the second mounting surface 2212 are located on opposite sides of the first mounting surface 2211 and are both set at an angle to the first mounting surface 2211. The clamping surface 2213 is used to abut against the front-end module frame 10. The second mounting surface 2212 is fixedly connected to the base 1. The movable clamping part 222 is mounted on the first mounting surface 2211. A clamping space is formed between the movable clamping part 222 and the clamping surface 2213. By moving the movable clamping part 222, the size of the clamping space can be adjusted, thereby clamping or releasing the front-end module frame 10.

[0041] More specifically, the movable clamping part 222 adopts a toggle clamp, such as a horizontal toggle clamp, which utilizes the lever principle to form a force-multiplying mechanism through connecting rods, thereby fixing larger components with a smaller force and having a self-locking function. Horizontal toggle clamps are existing technology and will not be described in detail here. It is important to emphasize that there are two first clamping members 22, spaced apart on the base 1, to improve the stability of the cover locking device when fixed to the front module frame 10.

[0042] It is understandable that, in order to improve positioning accuracy, the first limiting part 101 and the first limiting member 21 are interference-fitted. When assembling the hood lock 20 and the front module frame 10 in batches, the first limiting member 21, which is used multiple times, will inevitably wear out. Therefore, in this embodiment, the first limiting member 21 is connected to the base 1 by a detachable connection method including but not limited to bolt connection and snap-fit. Moreover, the first limiting member 21 is made of rubber or resin, which can not only achieve interference fit with the first limiting part 101, but also reduce the weight of the entire hood locking device, making it easier for operators to operate, and at the same time prevent scratches on the front module frame 10.

[0043] Similarly, the fixing clamping part 221 is connected to the base 1 by a detachable connection method including but not limited to bolt connection and snap-fit, so as to facilitate timely replacement of the fixing clamping part 221. The fixing clamping part 221 is also made of rubber or resin. Taking the bolt connection between the fixing clamping part 221 and the base 1 as an example, a mounting hole is provided on the second mounting surface 2212 for passing bolts through.

[0044] In this embodiment, the second limiting member 31 and the first clamping member 22 are respectively installed on two opposite sides of the base 1. In order to prevent the cover lock 20 from detaching from the contour groove of the second limiting member 31, at least part of the groove wall of the contour groove is magnetic so as to attract the cover lock 20 into the contour groove.

[0045] Specifically, the second limiting member 31 includes a main body 311, a second limiting part 312, and a third limiting part 313. The second limiting part 312 and the third limiting part 313 are detachably disposed on opposite sides of the main body 311 to cooperate with the main body 311 in forming a contoured groove. When the hood positioning device is fixed to the front module frame 10, the contoured groove has an upward-facing opening, through which the hood lock 20 can enter the contoured groove from top to bottom. Both the second limiting part 312 and the third limiting part 313 are detachably connected to the main body 311, which facilitates replacement of the second limiting part 312 and the third limiting part 313 after deformation or wear, thereby reducing maintenance costs. The second limiting part 312 and the third limiting part 313 are also made of rubber or resin.

[0046] refer to Figure 4 and Figure 5 As shown, a limiting block is bent on one side of the main body 311. The two sides of the main body 311 located on opposite sides of the limiting block are respectively connected to the second limiting part 312 and the third limiting part 313. The second limiting part 312 and the third limiting part 313 are each bent on the side away from the main body 311 and have limiting blocks. The limiting blocks on the main body 311, the second limiting part 312 and the third limiting part 313 serve as the sidewalls of the contour groove and limit the cover lock 20.

[0047] More specifically, the main body 311 includes a base part and a magnetic part. The magnetic part is sandwiched between the base part and the base 1. Compared with the main body 311 being made entirely of magnetic material, only the magnetic part is made of magnetic material, which can reduce the magnetic force to a certain extent and prevent the cover lock 20 from being unable to detach from the contour groove after assembly. Moreover, the separate main body further reduces the processing difficulty of the second limiting member 31.

[0048] The second clamping member 32 is fixed to the base 1, as shown in the reference. Figure 3 As shown, the second clamping member 32 also employs a toggle clamp, such as a vertical toggle clamp. Vertical toggle clamps are also existing technology, and their operating principles and the connection relationships between the components will not be elaborated here. It is important to emphasize that the second clamping member 32 has two clamping parts, both of which can abut against the hood lock 20 and apply pressure to it, preventing the hood lock 20 from disengaging from the second limiting member 31. Furthermore, both clamping parts are made of rubber or resin, which reduces the weight of the hood locking device and prevents damage to the hood lock 20.

[0049] In this embodiment, as Figure 1 , Figure 6As shown, the base 1 is divided into two parts to reduce the processing difficulty. The base 1 includes a first mounting part 11, a second mounting part 12, and a third mounting part 13. The second mounting part 12 and the third mounting part 13 are respectively fixed to opposite sides of the first mounting part 11 by means including but not limited to bolt connections. The first mounting part 11 has a third mounting surface 111, a fourth mounting surface 112, a fifth mounting surface 113, a sixth mounting surface 114, and a seventh mounting surface. The third mounting surface 111 and the fifth mounting surface 113 are respectively disposed on opposite sides of the fourth mounting surface 112 and are angled to the fourth mounting surface 112. The sixth mounting surface 114 and the fifth mounting surface 115 are angled to the fourth mounting surface 112. The seventh mounting surface is also located on opposite sides of the fourth mounting surface 112 and connects to the third mounting surface 111 and the fifth mounting surface 113. The first end of the first limiting member 21 is fixed to the third mounting surface 111, and the second end of the first limiting member 21 is set at an angle to the third mounting surface 111 so that the second end of the first limiting member 21 can be inserted into the insertion hole. The second limiting member 31 is fixed to the fourth mounting surface 112. The second mounting part 12 and the third mounting part 13 are respectively fixed to the sixth mounting surface 114 and the seventh mounting surface. The second mounting part 12 and the third mounting part 13 are respectively fixed with the first clamping member 22, and the second clamping member 32 is fixed to the fifth mounting surface 113. Specifically, gaskets are filled between the first mounting part 11 and the second mounting part 12, and between the first mounting part 11 and the third mounting part 13, to prevent foreign objects from entering the gaps.

[0050] refer to Figure 6 As shown, a mounting groove is also provided on the third mounting surface 111, and a threaded hole is provided in the mounting groove. The first end of the first limiting member 21 is embedded in the mounting groove and bolted to the first mounting part 11. The mounting groove is used to limit the first limiting member 21. Based on this, the position between the first limiting member 21 and the second limiting member 31 installed on the first mounting part 11 is determined. Then, the front module frame 10, whose position is determined by the first limiting member 21 cooperating with the first limiting part 101 and the hood locking device, and the hood lock 20, whose position is determined by the second limiting member 31 and the hood locking device, are indirectly limited.

[0051] refer to Figure 1 and Figure 7 As shown, in order to facilitate the application of force, the hood locking device in this embodiment also includes a handle 4, which is set to an approximate U-shape, with its two ends fixed to the second mounting part 12 and the third mounting part 13, respectively.

[0052] When assembling the hood lock 20, the hood lock 20 is first pre-installed in the contour groove, the first limiting member 21 is inserted and engaged with the first limiting part 101, and then the hood lock positioning device is fixed on the front module frame 10 by the first clamping member 22. Then the hood lock 20 is fixed in the contour groove by the second clamping member 32, thus completing the positioning of the hood lock 20 and the front module frame 10. Subsequently, the assembly work between the hood lock 20 and the front module frame 10 can be carried out.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
