[0025] Please refer to the reference. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of an embodiment of the front cover lock positioning device provided in this application. Figure 2 yes Figure 1 A side view structural schematic diagram of the positioning device. This application provides a positioning device 100 for a front cover lock, which includes a device body 1 and a flipping mechanism 2. The device body 1 is provided with a first positioning component 11 and a second positioning component 12. The first positioning component 11 is used to fix the lock body of the front cover lock, and the second positioning component 12 is used to connect with the front module of the vehicle. The second positioning component 12 includes a plurality of positioning pins 121, which are detachably inserted into the injection molding structure groove of the front module, and the positioning pins 121 are configured to conform to the injection molding structure groove. A part of the flipping mechanism 2 is connected to the device body 1, and the other part is detachably connected to the front module for cooperating with the device body 1 to clamp the front module. With the above structure, the lock body of the front cover lock can be fixed to the main body 1 of the device, and the main body 1 of the device can be connected to the front module through the second positioning component 12. Furthermore, the main body 1 of the device and the flipping mechanism 2 can cooperate to clamp the front module, thereby realizing the positioning and installation of the lock body on the front module, improving or avoiding the phenomenon of the lock body shifting when installed on the front module, reducing labor costs and improving installation efficiency.

[0026] Specifically, taking the direction of gravity as the first direction D1, when clamping the front-end module, the other part of the device body 1 facing the flipping mechanism 2 is the second direction D2. The first direction D1 is perpendicular to the second direction D2, and the third direction D3 is perpendicular to both the first direction D1 and the second direction D2. Typically, the front-end module of a vehicle is injection molded. After injection molding, several injection-molded structural grooves with a depth direction parallel to the second direction D2 are formed in the front-end module. Since the strength of the front-end module is relatively low and insufficient to provide additional positioning holes for bolts and other structures, the positioning pin 121 in this embodiment is designed to conform to the injection-molded structural grooves, allowing the positioning pin 121 to be inserted into the injection-molded structural grooves along the second direction D2, thereby achieving the connection between the device body 1 and the front-end module and improving stability. The flipping mechanism 2 can cooperate with the device body 1 to clamp the front-end module in the middle, that is, the device body 1 is installed onto the front-end module from one side, and the flipping mechanism 2 abuts against the front-end module from the other side, which can further improve stability and improve or prevent the device body 1 from shifting when the lock body is installed onto the front-end module. It should be noted that the flipping mechanism 2 can rotate relative to the main body 1 of the device. That is, when the lock body is installed on the front module, the flipping mechanism 2 can rotate to abut against the front module to play a clamping and fixing role, and limit the displacement of the lock body in the second direction D2. After the lock body is installed, the flipping mechanism 2 can rotate to disengage from the front module so that the main body 1 of the device can be removed from the front module.

[0027] In use, the operator can first obtain the front cover lock and the positioning device 100 of the front cover lock in this embodiment of the application, fix the lock body on the device body 1, then install the device body 1 on the front module, and then use the flipping mechanism 2 for further fixation. Then, through external operating parts, such as tightening tools, electric wrenches, bolts, etc., the lock body is installed into the front module. Finally, the flipping mechanism 2 is released to take out the device body 1, thus completing the positioning and installation of the lock body.

[0028] In one specific embodiment, a plurality of locating pins 121 can correspond one-to-one with a plurality of injection molding structural grooves to improve the tightness of the connection between the main body 1 of the device and the front-end module. In another specific embodiment, portions of the plurality of locating pins 121 can also be designed to be inserted into the ends of the front-end module in the first direction D1 and abut against the top end to provide support and improve the stability of the connection. Considering the existence of draft angle and dimensional tolerances, a gap can be reserved between the locating pins 121 and the injection molding structural grooves, with the gap size between 0 mm and 0.5 mm, such as 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, and 0.5 mm.

[0029] Please continue to combine Figure 3 , Figure 3 yes Figure 1A schematic diagram of the positioning device from a frontal view. In one embodiment of this application, the first positioning component 11 includes a positioning groove 111, and a portion of the lock body is fixed within the positioning groove 111.

[0030] Specifically, the shape and size of the positioning groove 111 are not required. It can be set according to the partial structure of the lock body. The positioning groove 111 can restrict the movement of the lock body and realize the positioning of the lock body, thereby improving or avoiding the phenomenon of lock body offset during installation.

[0031] In one embodiment of this application, the first positioning component 11 includes a positioning base plate 112 and two positioning protrusions 113 disposed opposite to each other on the positioning base plate 112. The positioning protrusions 113 extend along the first direction D1, and the two positioning protrusions 113 and the positioning base plate 112 together form a T-shaped positioning groove 111.

[0032] Specifically, the main body 1 of the device may include a plate, a positioning base plate 112 being a recessed surface on the plate, and two positioning protrusions 113 protruding from the positioning base plate 112 along the second direction D2 and spaced apart along the third direction D3, thereby forming a T-shaped positioning groove 111 together with the positioning base plate 112. The T-shaped positioning groove 111 can limit the displacement of the lock body in the first direction D1 and the third direction D3, improving the stability of positioning.

[0033] In one embodiment of this application, the first positioning component 11 further includes a plurality of positioning elements 114, which are distributed on two edges of the device body 1 in the first direction D1, and the plurality of positioning elements 114 abut against a portion of the lock body.

[0034] Specifically, the positioning member 114 protrudes from the plate surface of the device body 1 along the second direction D2, with one part located at the top edge of the device body 1 in the first direction D1 and the other part located at the bottom edge of the device body 1 in the first direction D1. By abutting against part of the lock body structure, the displacement of the lock body in the first direction D1 can be restricted, thereby improving the stability of positioning.

[0035] Furthermore, several positioning elements 114 can be arranged at intervals along the third direction D3 to improve or prevent the lock body from tilting or rotating. The cooperation between the positioning elements 114 and the positioning grooves 111 further enhances the accuracy and stability of positioning.

[0036] In one embodiment of this application, the main body 1 of the device is further provided with a plurality of mounting holes 13, which are arranged at intervals along the first direction D1. The plurality of mounting holes 13 are used for fasteners to pass through so as to install the lock body to the front end module.

[0037] Specifically, after the lock body is installed on the main body 1, the main body 1 is then installed on the front-end module, and the lock body is then installed into the front-end module using fasteners. The opening direction of the mounting hole 13 is parallel to the second direction D2. When installing the lock body, the fasteners can directly pass through the mounting hole 13 and fix the lock body to the front-end module. The fasteners may include bolts, screws, etc.

[0038] In one embodiment of this application, the main body 1 of the device is further provided with a clearance hole 14, which is spaced apart from the mounting hole 13. The clearance hole 14 is used to avoid external operating components when the lock body is installed on the front end module.

[0039] Specifically, to further improve the stability of the lock body mounted on the front-end module, the lock body can be reinforced with fasteners. In one specific embodiment, the fastener can be larger than the fixing component to enhance the reinforcement effect. During installation, an external operating tool, such as an electric wrench, is required, and the clearance hole 14 allows the drill bit of the electric wrench to pass through easily.

[0040] Furthermore, in order to balance the force on the front module, two clearance holes 14 can be set on the third direction D3, located at both ends of the device body 1 respectively. Similarly, two sets of mounting holes 13 are also located at both ends of the device body 1 respectively.

[0041] In one embodiment of this application, as Figure 1 and Figure 2 As shown, the flipping mechanism 2 includes a first support 21, a second support 22, and a rotating part 23. The first support 21 is connected to the main body 1 of the device, and the second support 22 is detachably connected to the front-end module. Both the first support 21 and the second support 22 are rotatably connected to the rotating part 23. Specifically, the rotating part 23 can rotate relative to the first support 21, and the second support 22 can rotate relative to the rotating part 23.

[0042] In use, the rotating part 23 can be rotated in a direction away from the main body 1, thereby driving the second bracket 22 away from the main body 1, opening the space between the flipping mechanism 2 and the main body 1, and then the lock body is installed on the main body 1; after the main body 1 is installed and connected to the front module, the rotating part 23 is rotated closer to the main body 1, thereby driving the second bracket 22 closer to and abutting the front module; after the lock body is installed on the front module, the rotating part 23 is rotated in a direction away from the main body 1, thereby driving the second bracket 22 away from the front module.

[0043] In one embodiment of this application, as Figure 2As shown, the first bracket 21 has a handle 211 on the side away from the main body 1; the second bracket 22 has a pressing part 221 on the side facing the front module; the rotating part 23 includes a rotating body 231 and a control rod 232. The rotating body 231 is rotatably connected to the first bracket 21 and the second bracket 22 respectively, and the control rod 232 is rotatably connected to the rotating body 231 and the second bracket 22. The control rod 232 can control the rotating body 231 to rotate relative to the first bracket 21; the control rod 232 itself can rotate relative to the rotating body 231, thereby driving the second bracket 22 to rotate relative to the rotating body 231.

[0044] Specifically, the handle 211 is used to grasp the entire positioning device 100, making it easy to pick up. The clamping part 221 may include a clamping block, which is used to abut against the front end module during installation. The rotating body 231 may include a box structure with a hollow center formed by two layers of plates. The rotating body 231 is provided with a first rotation point A1, a second rotation point A2, and a third rotation point A3. The first rotation point A1 is used to connect to the first bracket 21, so that the rotating body 231 can rotate relative to the first bracket 21 with the first rotation point A1 as the base point. The second rotation point A2 is used to connect to the control rod 232, so that the control rod 232 can rotate relative to the rotating body 231 with the second rotation point A2 as the base point. The third rotation point A3 is used to connect to the second bracket 22, so that the second bracket 22 can rotate relative to the rotating body 231 with the third rotation point A3 as the base point. To facilitate the rotation of the rotating body 231 and the second support 22, the ends of the first support 21 and the second support 22 that connect to the rotating body 231 are both located inside the housing of the rotating body 231. The control rod 232 is connected to the second support 22 via a hinge 233. The rotating body 231 has a notch 234, within which the hinge 233 can rotate. When the hinge 233 rotates to its maximum angle away from the main body 1, it abuts against the edge of the plate, thereby driving the rotating body 231 to rotate.

[0045] In use, lifting the control lever 232 causes it to rotate relative to the rotating body 231, which in turn drives the second bracket 22 to rotate relative to the rotating body 231 and move it away from the device body 1. After the hinge 233 abuts against the edge of the plate, it drives the rotating body 231 to rotate, so that the lock body can be installed onto the device body 1. Lowering the control lever 232 is the reverse process, which will not be described in detail here. It should be noted that the lifting direction of the control lever 232 is the opposite direction of the first direction D1.

[0046] In one specific embodiment, combined with Figures 1 to 3As shown, the second support 22 includes a first connecting rod 222 and a second connecting rod 223. The first connecting rod 222 is connected to the rotating part 23 for rotation. The second connecting rod 223 is provided with a pressing part 221 for abutting against the front end module. The first connecting rod 222 and the second connecting rod 223 are connected by a lead screw 224. An adjusting member 225 is provided on the side of the second connecting rod 223 facing the device body 1. The adjusting member 225 is sleeved on the lead screw 224. By moving the adjusting member 225 on the lead screw 224, the second connecting rod 223 can be pushed closer to or further away from the device body 1, thereby adjusting the distance between the pressing part 221 and the front end module, improving or avoiding the situation where the pressing part 221 cannot abut against the front end module due to excessive spacing in the second direction D2.

[0047] In one embodiment of this application, in conjunction with reference to... Figures 1 to 3 The positioning device 100 also includes a first adjusting block 3 and a limiting member 4. The limiting member 4 is connected to the device body 1 and is used to limit the offset of the device body 1. The first adjusting block 3 is disposed between the limiting member 4 and the device body 1 and is used to adjust the distance between the limiting member 4 and the device body 1.

[0048] Specifically, the limiting member 4 is disposed on the other end of the device body 1 opposite to the positioning pin 121. When the device body 1 is installed on the front end module, it can abut against the front end module to limit the offset of the device body 1 in the first direction D1. In use, the size or number of the first adjusting block 3 can be increased or decreased according to the actual situation so that the limiting member 4 can abut against the front end module.

[0049] In one embodiment of this application, the positioning device 100 further includes a second adjustment block 5, which is disposed on the device body 1 and is used to adjust the size of the clearance hole 14.

[0050] Specifically, two second adjustment blocks 5 can be set, the two second adjustment blocks 5 are arranged at intervals along the first direction D1, and the line connecting the two second adjustment blocks 5 passes through the center of the clearance hole 14, so as to adjust the size of the clearance hole 14 by increasing or decreasing the size or number of the second adjustment blocks 5 in the third direction D3.

[0051] Furthermore, such as Figure 1 As shown, the positioning device 100 also includes a third adjusting block 6, which is disposed between the clamping part 221 and the second bracket 22 to control the position of the clamping part 221 and ensure that the clamping part 221 can abut against the front end module. It should be noted that the first adjusting block 3, the second adjusting block 5 and the third adjusting block 6 can be installed on the device body 1 and the second bracket 22 respectively by bolts, or they can be installed by other means.

[0052] It should be noted that the terms "horizontal" and "vertical" do not imply that the components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. Similarly, the terms "parallel" and "perpendicular" do not imply that the components are absolutely parallel or perpendicular, but rather that they can have a certain angular deviation. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted. In addition, the orientations or positional relationships indicated by terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" are based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships that are commonly used when the product of this application is in use. They are only for the purpose of describing the embodiments of this application and simplifying the description, 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 application.

[0053] It is understood that the term "multiple" in this document means at least two, such as two, three, etc., unless otherwise specified. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices. The term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects are in an "or" relationship.

[0054] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
