Description

Technical Field

[0001] This utility model relates to the field of automobile production and assembly technology, and in particular to a hood locking tool. Background Technology

[0002] In the process of automobile assembly, in order to ensure the precise installation position of parts and improve the efficiency of parts installation, assembly workshops usually use some tooling to assist in the positioning of parts. For example, the hood lock plays an important role in fastening and locking the front hood of the car, so the positional accuracy of the hood lock is particularly important, and therefore, hood lock positioning tooling is needed to assist in the installation of the hood lock.

[0003] Existing hood locking fixtures are used to assist in the installation of hood locks. The hood locking fixture is first positioned and installed at the front-end module of the vehicle, and then the hood lock abuts against the fixture to determine its installation position. However, due to the complexity of the automotive manufacturing process, the positioning of the hood locking fixture often becomes inaccurate in practical applications. When this problem occurs, the position of the hood locking fixture needs to be adjusted, and the movement of the hood locking fixture also causes the hood lock to move.

[0004] The hood lock usually has a groove for matching and locking with the front hood of the car. In order to make the front hood close smoothly, the bottom of the groove is usually set to be arc-shaped and a certain fitting allowance is provided. However, as a result, the movement process of the hood locking position tool often causes the movement distance of the hood lock to be not completely consistent with the movement distance of the hood locking position tool, resulting in the position of the hood lock being offset or even the angle being deviated. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a cover locking fixture.

[0006] A hood locking fixture includes: a base; a positioning component connected to the base, wherein the side of the positioning component facing away from the base is used to abut against a front-end module of a vehicle; and a contouring component connected to the side of the base where the positioning component is located, wherein the contouring component includes at least two contouring blocks, the contouring blocks being used to cooperate with a hood lock, adjacent contouring blocks being spaced apart, and each contouring block having a rounded corner at the end away from the base.

[0007] With this configuration, the base is fixedly connected to the vehicle's front-end module via a positioning component, thus fixing the relative position of the base. The contouring component is used to connect with the hood lock. Because the two contouring blocks of the contouring component are spaced apart, the points of contact between the two blocks and the grooves in the hood lock are further apart, resulting in a more stable connection. Furthermore, the two contouring blocks increase the contact area between the contouring component and the hood lock, further enhancing the connection stability. The rounded end shape allows for better adaptation of the contouring blocks to the arc-shaped grooves of the hood lock. When the hood lock positioning fixture is adjusted, it allows the hood lock to move stably along with the fixture. During subsequent installation, the positioning effect of the hood lock positioning fixture on the hood lock is also better, resulting in a more precise installation position.

[0008] In one embodiment, the contour block includes a mating portion and an extension portion, the extension portion extending in a direction away from the base, the mating portion being connected to the extension portion, and the mating portion having the rounded corners.

[0009] In one embodiment, the contouring component further includes a base connected to the side of the base where the positioning component is located, and the contouring block is connected to the base.

[0010] In one embodiment, the base has an inclined surface on the side facing away from the base, and the inclined surface is at an angle to the side of the base where it connects to the base.

[0011] In one embodiment, the positioning component includes a support block for abutting against the front-end module of the vehicle, the support block being connected to the base, and at least one first gasket being disposed between the support block and the base, the support block pressing against the first gasket, and the first gasket being detachably disposed between the support block and the base.

[0012] In one embodiment, the positioning component further includes a connecting block connected to the support block, and at least one second gasket is provided between the connecting block and the support block. The connecting block and the support block press the second gasket together, and the thickness direction of the second gasket is perpendicular to the thickness direction of the first gasket.

[0013] In one embodiment, the positioning component further includes a fixing block connected to the connecting block, and at least one third gasket is disposed between the fixing block and the connecting block. The fixing block and the connecting block are pressed against the third gasket, and the thickness direction of the third gasket, the thickness direction of the second gasket, and the thickness direction of the first gasket are all perpendicular to each other. The fixing block is provided with a positioning pin protruding along the thickness direction of the first gasket.

[0014] In one embodiment, the support block has a first positioning hole, and the base has a first connecting hole coaxially arranged with the first positioning hole; a first connector passes through the first positioning hole and the first connecting hole; and / or,

[0015] The connecting block has a second positioning hole, and the support block has a second connecting hole coaxially arranged with the second positioning hole; a second connecting member passes through the second positioning hole and the second connecting hole; and / or...

[0016] The fixing block has a third positioning hole, and the connecting block has a third connecting hole coaxially arranged with the third positioning hole. A third connecting member passes through the third positioning hole and the third connecting hole.

[0017] In one embodiment, the contouring component is disposed at the middle of the base along its length, and the positioning component includes two positioning units, each of which includes the support block, the connecting block, and the fixing block. The two positioning units are symmetrically disposed on both sides of the contouring component.

[0018] In one embodiment, the hood locking fixture further includes a handle connected to the base on the side away from the contouring component.

[0019] Compared to existing technologies, this invention uses a contouring component and a contouring block that better matches conventional cover locks to make the cover lock positioning fixture and the cover lock fit more tightly. This allows the cover lock positioning fixture to move synchronously when adjusting its position, preventing the cover lock from shaking or shifting. Attached Figure Description

[0031] Please see Figures 1-4 This utility model provides a cover locking fixture 100, which works more closely with the cover lock 200, so that the cover locking fixture 100 can synchronously drive the cover lock 200 to move stably when adjusting the position, avoiding the cover lock 200 from deviating from the expected position, and the position of the cover lock 200 can be more accurately assembled in the subsequent assembly process.

[0032] The hood locking fixture 100 includes a base 10, a positioning component 20, and a contouring component 30. The positioning component 20 is connected to the base 10, and the side of the positioning component 20 facing away from the base 10 is used to abut against the front-end module 300 of the vehicle. The contouring component 30 is connected to the side of the base 10 where the positioning component 20 is located. The contouring component 30 includes at least two contouring blocks 31, with adjacent contouring blocks 31 spaced apart, and each contouring block 31 has a rounded corner at the end away from the base 10.

[0033] Thus, the base 10 is fixedly connected to the vehicle front module 300 via the positioning component 20, thereby fixing the relative position of the base 10. The contouring component 30 is used to connect with the hood lock 200. Because the two contouring blocks 31 of the contouring component 30 are spaced apart, the force-bearing points of the two contouring blocks 31 and the grooves opened in the hood lock 200 are farther apart, resulting in a more stable connection with the hood lock 200. Furthermore, the two contour blocks 31 increase the contact area between the contour component 30 and the hood lock 200, thereby further improving the connection stability between the contour component 30 and the hood lock 200. The rounded end shape allows the contour block 31 to better fit the arc-shaped groove of the hood lock 200. When the hood locking positioning fixture 100 is adjusted, the hood lock 200 can move stably together with the hood locking positioning fixture 100. In the subsequent installation process, the positioning effect of the hood locking positioning fixture 100 on the hood lock 200 is also better, making the installation position of the hood lock 200 more accurate.

[0034] Furthermore, the contour block 31 includes a mating portion 312 and an extension portion 311. The extension portion 311 extends away from the base 10, and the mating portion 312 is connected to the extension portion 311, with rounded corners on the mating portion 312. Thus, the extension portion 311 allows the contour block 31 to extend into the groove of the hood lock 200, resulting in a larger contact area and more contact points with the hood lock 200. The mating portion 312 mates with the bottom wall of the groove in the hood lock 200, and the rounded corners create a tighter fit with the predominantly arc-shaped bottom of the hood lock 200 groove.

[0035] In this embodiment, the length of the contour block 31 is at least 20mm to ensure that it has sufficient contact area with the hood lock 200 and sufficient depth to extend into the groove of the hood lock 200.

[0036] Of course, in other embodiments, if the groove shape of the cover lock 200 is rectangular, the structure of the contour block 31 can also be adapted to be a rectangular block, and is not limited to the shape of this embodiment.

[0037] The contouring component 30 also includes a base 32, which is connected to the side of the base 10 where the positioning component 20 is located. The contouring block 31 is connected to the base 32. In this way, the base 32 can facilitate the connection between the contouring block 31 and the base 10. The base 10, the contouring block 31 and the base 32 can be processed separately to reduce the processing difficulty. During the assembly process, the positions of each other can be adjusted more easily.

[0038] Of course, it is understandable that, in order to make the connection between the various structures stronger, the base 32 and the contour block 31 can also be integrally formed.

[0039] The base 32 has an inclined surface 321 on the side facing away from the base 10, and the inclined surface 321 is set at an angle to the side of the base 32 that connects to the base 10. Thus, the contour block 31 is also set at an angle to the base 10. After the base 10 is installed on the front module of the car for assembly, the contour block 31 can extend obliquely upward at an angle to match the installation angle of the hood lock 200 and facilitate assembly by the installer.

[0040] The positioning component 20 includes a support block 21 connected to the base 10. At least one first gasket 22 is disposed between the support block 21 and the base 10. The support block 21 presses against the first gasket 22, and the first gasket 22 is detachably disposed between the support block 21 and the base 10. Thus, since the support block 21 abuts against the vehicle front module 300, the distance between the support block 21 and the base 10 is the same as the distance between the base 10 and the vehicle front module 300. The thickness direction of the first gasket 22 is defined as the first direction. Therefore, adjusting the thickness of the first gasket 22 can adjust the position of the base 10 and even the hood locking fixture 100 in the first direction, thereby realizing the position adjustment function of the hood locking fixture 100 in the first direction.

[0041] Furthermore, the positioning component 20 also includes a connecting block 23, which is connected to the support block 21. At least one second gasket 24 is provided between the connecting block 23 and the support block 21. The connecting block 23 and the support block 21 press the second gasket 24 together, and the thickness direction of the second gasket 24 is perpendicular to the thickness direction of the first gasket 22. Thus, since the connecting block 23 and the support block 21 press the second gasket 24 together, the thickness of the second gasket 24 is the distance between the connecting block 23 and the support block 21. The thickness direction of the second gasket 24 is defined as the second direction. Therefore, adjusting the thickness of the second gasket 24 can realize the position adjustment function of the cover locking fixture 100 in the second direction.

[0042] Furthermore, the positioning component 20 also includes a fixing block 25, which is connected to the connecting block 23. At least one third gasket 26 is provided between the fixing block 25 and the connecting block 23. The fixing block 25 and the connecting block 23 are pressed against the third gasket 26, and the thickness directions of the third gasket 26, the second gasket 24, and the first gasket 22 are all perpendicular to each other. The fixing block 25 has a positioning pin protruding along the thickness direction of the first gasket 22. Thus, since the fixing block 25 and the connecting block 23 press against the third gasket 26, the thickness of the third gasket 26 is the distance between the fixing block 25 and the connecting block 23. The thickness direction of the third gasket 26 is defined as the third direction. Therefore, adjusting the thickness of the third gasket 26 can realize the position adjustment function of the cover locking fixture 100 in the third direction.

[0043] Preferably, multiple first gaskets 22 are provided between the support block 21 and the base 10, all of which are rectangular in structure. These gaskets are arranged in parallel and evenly spaced along their arrangement direction, thereby making the connection between the support block 21 and the base 10 more stable. Similarly, multiple second gaskets 24 are also provided between the connecting block 23 and the support block 21, evenly spaced along their arrangement direction, thereby ensuring balanced force distribution between the connecting block 23 and the support block 21. Likewise, multiple third gaskets 26 are also provided between the fixing block 25 and the connecting block 23. These third gaskets 26 are arranged in parallel and evenly spaced, thereby improving the connection stability between the fixing block 25 and the connecting block 23.

[0044] In this embodiment, the first gasket 22, the second gasket 24, and the third gasket 26 are all configured as rectangular structures. In other embodiments, they can also be configured as circular structures, triangular structures, polygonal structures, etc., and are not limited to the above embodiments.

[0045] Preferably, in this embodiment, the first gasket 22, the second gasket 24 and the third gasket 26 are configured in various ways, with a thickness of 1mm-3mm, and are optimized according to the posture of the car hood.

[0046] The fixing block 25 is provided with a pin 252, which is used to fix it to the front module 300 of the vehicle. In other embodiments, the fixing block 25 can also be provided with screws, bolts or other structures to fix it to the front module 300 of the vehicle.

[0047] To facilitate the connection between the above structures, the support block 21 is provided with a first positioning hole 211, and the base 10 is provided with a first connecting hole coaxial with the first positioning hole 211. A first connecting member 212 passes through the first positioning hole 211 and the first connecting hole; and / or, the connecting block 23 is provided with a second positioning hole, and the support block 21 is provided with a second connecting hole 213 coaxial with the second positioning hole. A second connecting member 232 passes through the second positioning hole and the second connecting hole 213; and / or, the fixing block 25 is provided with a third positioning hole, and the connecting block 23 is provided with a third connecting hole coaxial with the third positioning hole. A third connecting member 251 passes through the third positioning hole and the third connecting hole.

[0048] Thus, the first connector 212 ensures a tight connection between the support block 21 and the base 10. During the replacement of the first gasket 22, the support block 21 and the base 10 maintain their connection thanks to the limiting effect of the first connector 212, facilitating the replacement of the first gasket 22. After the first gasket 22 is replaced, the first connector 212 is used to bring the two closer together to press the first gasket 22 firmly. The second connector 232 and the third connector 251 similarly facilitate the connection between the connecting block 23 and the support block 21, as well as between the fixing block 25 and the connecting block 23, improving the positional stability and connection strength of the support block 21, the connecting block 23, and the fixing block 25. Further details are omitted here.

[0049] For example, the first connector 212, the second connector 232 and the third connector 251 are all bolt structures, while the first positioning hole 211, the first connecting hole, the second positioning hole, the second connecting hole 213, the third positioning hole and the third connecting hole are all threaded holes. In this way, the first connector 212, the second connector 232 and the third connector 251 can make the two parts they are connected to (such as the support block 21 and the connecting block 23) move closer or further apart by a simple rotation process, thereby achieving position adjustment and improving the stable connection effect.

[0050] The contouring component 30 is located at the middle of the base 10 along its length. The positioning component 20 includes two positioning units, each comprising a support block 21, a connecting block 23, and a fixing block 25. The two positioning units are symmetrically arranged on both sides of the contouring component 30. In this way, the two positioning units enable a more stable connection between the base 10 and the vehicle front-end module 300, and a more balanced stress distribution.

[0051] The hood locking fixture 100 also includes a handle 40, which is connected to the side of the base 10 away from the contouring component 30. The handle 40 facilitates the assembly personnel in gripping and operating the hood locking fixture 100.

[0052] Compared with the prior art, this utility model sets up a contouring component 30 and a contouring block 31 that has a better matching degree with the conventional cover lock 200 to make the fit between the cover locking positioning fixture 100 and the cover lock 200 tighter. This allows the cover locking positioning fixture 100 to move the cover lock 200 synchronously when adjusting its position, thus preventing the cover lock 200 from shaking or shifting.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
