[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0049] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0050] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0051] The tailgate structure of the car structure is connected to the latch structure on the rear panel through the door lock on the tailgate, thereby realizing the locking of the car tailgate. Therefore, the positioning of the car latch is the basis for achieving good connectivity between the above structures. Generally speaking, after the door lock and latch have installation deviations, the following problems are very likely to occur: the Y-direction collision between the lock and the latch on a bumpy road is likely to produce abnormal noise; during the tailgate closing process, the latch and the lock have too much contact and the collision is more obvious; during the tailgate opening process, the tailgate shakes. The traditional centering solution for the latch and the door lock generally includes knocking to adjust the latch position, or locking the door during the installation process to achieve positioning between the door lock and the latch. In the above two methods, the first one may cause the latch structure to deform, and the other one involves frequent unlocking and door opening actions, which are not convenient in actual application.

[0052] The present invention provides a car tailgate latch tool 100 .

[0053] See also Figures 1 to 3In one embodiment of the present invention, a tailgate latch tool 100 is used to position the tailgate latch. Conventional tailgate door lock and latch positioning and installation operations are relatively cumbersome. For example, conventional installation and alignment methods generally fall into two categories: the first installation and positioning method involves first tightening the latch against the rear panel structure to weaken the latch reinforcement plate, and then adjusting the latch position by tapping the latch. The second installation and positioning method involves closing the tailgate, allowing the door lock and latch to engage automatically, and then tightening the latch after engagement. Of these two most commonly used door lock and latch positioning and installation methods, the first weakens the latch reinforcement plate, potentially reducing the latch structure's installation strength during actual use and potentially causing the tailgate to shake after prolonged use. The second installation method is more cumbersome, requiring unlocking after the latch is positioned and tightened, and the rear panel requires a sealed cover. This is more costly than conventional solutions and is less convenient to implement. Taking the above problems into consideration, in this embodiment, the structure of the automobile tailgate lock catch tool 100 is configured as a movable structure. During actual use, the door lock and the lock catch are in a relatively separated state when aligned, thereby effectively solving the related problems existing in the above existing embodiments. Specifically, the main body 1 in this embodiment is the main installation structure. It is in the shape of an elongated plate, and its length direction corresponds to the long side direction of the rear panel of the automobile tailgate. It is arranged along a first direction on the horizontal plane. A fixing member and a guide member are provided on the main body 1 corresponding to the end face of the rear panel of the automobile tailgate, that is, on the installation surface 13. The fixing member can form a movable connection relationship with the upper end face of the rear panel of the automobile tailgate. In addition to being able to install the main body 1 on the rear panel of the automobile tailgate, it can also move the main body 1 on the end face of the rear panel when a force is applied. To ensure the direction of movement of the main body 1, during the actual installation and fixing process of the main body 1, the two guide portions 3 of the guide member are connected to the cut edges of the rear panel of the vehicle tailgate to restrict the main body 1 from moving in a first horizontal direction. In this embodiment, the relative position of the door lock drives the lock catch for positioning, so corresponding connecting structures are provided on the main body 1 for connecting with the door lock and the lock catch, respectively. In a specific implementation, the main body 1 is first visually adjusted in its installation position on the rear panel of the vehicle tailgate. The lock catch structure on the rear panel is connected via the lock catch fixing portion 4. Then, during the closing process of the tailgate, the door lock on the tailgate engages with the door lock fixing portion 5, thereby driving the main body 1 to move in the first direction on the rear panel of the vehicle tailgate, thereby adjusting the Y-axis position of the lock catch (the Y-axis direction of the lock catch corresponds to the longitudinal extension direction of the first direction).By making the door lock and the lock catch correspond to each other in the above manner, firstly, the door lock and the lock catch can be adjusted by separating them from each other, eliminating the need to frequently lock and unlock the door while adjusting the lock catch. In addition, the actual strength of the lock catch mounting plate is not reduced, and structural deformation caused by hammering the lock catch is avoided. At the same time, the operation is convenient and easy to implement.

[0054] Specifically, the main body 1 is configured as an I-shaped structure, with two first protrusions 11 and two second protrusions 12 formed at the four corners of its two ends in the longitudinal direction. Specifically, the two guide parts 3 are respectively mounted on the two first protrusions 11, and the fixing parts are correspondingly mounted on the two second protrusions 12. Through the above-mentioned configuration, the specific structure of the main body 1 can be simplified as much as possible, and its actual structural weight can be greatly reduced, which is conducive to improving the convenience during the actual installation process.

[0055] In this embodiment, the fixing member is configured to be fixed by magnetic attraction. Specifically, the fixing member includes two fixing portions 2 of identical structure. In the fixing portion 2, a plurality of sunken grooves 211 are provided on a horizontal end surface of the first mounting block 21 away from the mounting surface 13. The first magnet member 22 is sunken and installed in the sunken groove 211, and one end of the first magnet member 22 at least partially protrudes from the opening of the sunken groove 211. During the actual installation process, the outwardly protruding end of the first magnet member 22 is connected to the upper end surface of the rear panel, thereby achieving movable fixation of the main board 1. It is conceivable that the magnitude of the adsorption force can be adjusted according to the actual adsorption force required, thereby ensuring the stability of the main board 1 during movement.

[0056] Specifically, the guide portion 3 includes a mounting block structure 31 and a guide shaft structure 32, wherein the mounting block structure 31 and the guide shaft structure 32 each include two parts, a first shaft body 321 and a second shaft body 322 respectively mounted on the second mounting block 311 and the third mounting block 312, and the first guide shaft and the second guide shaft are arranged at a certain angle, and both can be connected with the two end surfaces adjacent to the rear panel trim, thereby limiting the movement direction of the main body 1, so that the main body 1 can only move along the first direction during movement. In the above structure, the specific use of the shaft structure for guidance can effectively reduce the friction between the relevant structure and the rear panel trim structure during contact, thereby making the guided movement of the main body 1 more stable.

[0057] The first and second shafts 321 and 322 are arranged at a 90-degree angle relative to each other. During actual contact, they respectively contact the two end surfaces adjacent to the outer trim, thereby limiting the X and Z directions of the main body 1. A clamping member is also provided on the second mounting block 311. During the actual fixing process, when the main body 1 drives the lock to move and its position is adjusted, it is subsequently necessary to tighten the bolts on the lock to completely secure the lock to the rear panel. Therefore, to ensure the accuracy of the lock position after adjustment, the clamping member and the first shaft 321 jointly clamp the rear trim of the vehicle tailgate after the position adjustment is completed, thereby preventing the lock from moving during the locking process, which could cause the lock position to shift.

[0058] In this embodiment, when the connection with the latch on the rear panel is established, the entire main body 1 structure can be moved to connect the clamping groove 421 on the clamp member 42 with the latch of the vehicle tailgate. The clamping groove 421 is a one-way opening structure, which can simultaneously drive the latch to move in the first direction during the movement of the main body 1 in the first direction. Specifically, a third gasket 422 is provided between the third protrusion 41 and the clamp member 42. The provision of the third gasket 422 can ensure that the clamp member 42 is maintained as close as possible to the middle position between the first protrusion 11 and the second protrusion 12 by adding or removing the third gasket 422 before the entire tooling structure is used.

[0059] A fourth protrusion 14 extends horizontally from one side of the main body 1, corresponding to the clamp 42. A stopper 51 in the door lock fixing portion 5 is mounted on this fourth protrusion 14. The vertically upward end of the stopper 51 is sunken, forming a dovetail groove 511, the opening of which gradually decreases inward from its end surface. A flexible member 512 is provided on the inclined inner wall of the dovetail groove 511. When the door lock is actually locked, the door lock contacts the flexible member 512 within the dovetail groove 511 and applies force during contact with the inclined side wall, thereby driving the main body 1 in the first direction. This in turn adjusts the Y-axis position of the lock catch.

[0060] like Figure 2As shown, an inclined mounting surface 13 is generally provided in the middle position of the rear panel of the automobile tailgate, and the lock structure is usually installed on the above-mentioned inclined surface with a reinforcement plate, so a certain inclination angle is formed between the upper end surface of the reinforcement plate of the lock and the horizontal plane. Generally speaking, two protruding convex structures are provided on the upper end surface of the reinforcement plate. In this embodiment, the fixing member is further improved in view of the actual structure of the above reinforcement plate. Specifically, a bottom support member 6 is provided on the mounting surface 13 corresponding to the position of the above-mentioned convex structure, and a fourth gasket 63 is provided between the fifth convex portion 61 of the bottom support member 6 and the fourth mounting block 62. Through the setting of the fourth gasket 63, the second magnet member 621 on the inclined surface of the fourth mounting block 62 can be adjusted to contact the end surface of the convex structure on the above-mentioned reinforcement plate, so that the main body 1 is fixed together by the first magnet member 22 and the second magnet member 621, thereby increasing the stability of the main body 1 during movement.

[0061] In addition, a handle structure 7 is provided on an end surface of the main board body 1 away from the mounting surface 13 , and when the main board body 1 is actually placed on the peripheral plate, the handle structure 7 can be used for operation.

[0062] And considering that the specific structures of different automobile tailgates may be different, in actual use, according to different tailgate structures, a first gasket 23 can be provided between the first mounting block 21 and the second protrusion 12, and a second gasket 33 can be provided between the second mounting block 311 and the third mounting block 312, so as to increase or decrease the applicability of the entire device by adding or reducing corresponding gaskets.

[0063] like Figures 4 and 5 The present invention also provides a method for using a tailgate latch tool 100 for an automobile. The method for using the tailgate latch tool 100 is applied to the tailgate latch tool 100. The tailgate latch tool 100 includes the disclosed contents of the above embodiments and thus has at least all the beneficial effects brought about by the technical solutions of the above embodiments. A detailed description thereof will not be repeated here. Specifically, the method for using the tailgate latch tool 100 for an automobile comprises the following steps:

[0064] Install the door lock of the car tailgate on the car tailgate, and install the lock catch of the car tailgate to the rear panel of the car tailgate, and keep the lock catch bolt in a loose state;

[0065] In actual operation, the door lock can be fixed to the tailgate of the car, and then the lock catch can be placed on the rear panel of the tailgate. Specifically, the rear panel structure of the car has a through-hole structure with a single-side size of 3mm. During the installation of the lock catch, the reinforcement plate of the lock catch is inserted through the through-hole structure with bolts and initially fixed to the through-hole structure. At this time, the lock catch is in a relaxed state and can move under external force.

[0066] Placing the main body 1 on the rear panel of the car tailgate, connecting the main body 1 to the lock of the car tailgate, and adjusting the position of the main body 1 to achieve rough positioning of the main body 1 in the first direction;

[0067] The entire main board body 1 is placed on the upper end surface of the rear panel through the handle structure 7, and the position of the automobile tailgate lock tooling 100 is preliminarily determined by visual inspection, and the entire main board body 1 is installed and fixed through the above-mentioned first shaft body 321, second shaft body 322 and related magnet parts, so as to achieve rough positioning of the entire main board body 1. During this process, it is necessary to pre-fix the lock buckle to the inner side of the clamping groove 421 so that the lock buckle has the effect of moving along the first direction.

[0068] Closing the tailgate of the car, so that the tailgate door lock and the main body 1 are self-positioned in the first direction, and the main body 1 is driven to slide on the rear panel of the tailgate of the car, so that the door lock and the lock buckle are self-adapted in the first direction;

[0069] After the lock buckle and the main body 1 are fixed, the door lock can be driven to move toward the dovetail groove 511 on the limit block 51 by closing the tailgate. When the door lock meets the inclined inner wall of the dovetail groove 511, the entire main body 1 is driven to move in the first direction, thereby realizing adaptive adjustment of the lock buckle in the Y direction. During this process, the lock buckle and the door lock are relatively separated. After the lock buckle is adjusted in position by the door lock, there is no need to perform an unlocking action, so it can be more convenient during actual operation.

[0070] Controlling the tailgate to open and locking the locking bolt on the rear panel of the tailgate of the vehicle;

[0071] After the lock catch is adjusted in the Y direction, the clamping member secures the main body 1 to prevent displacement. The tailgate is then opened, and the bolts on the lock catch reinforcement plate secure the lock catch to the rear panel. Once the lock catch and door lock are aligned, the entire main body 1 can be directly separated from the rear panel, greatly improving operational convenience.

[0072] The main body 1 is placed on the rear panel of the car tailgate, the main body 1 is connected to the lock of the car tailgate, and the position of the main body 1 is adjusted to achieve the rough positioning of the main body 1 in the first direction.

[0073] The freedom of movement of the main body 1 in the first direction is limited by two mutually perpendicular axial structures;

[0074] Before the final position of the main board body 1 is determined, the movement direction of the main board body 1 needs to be limited at the rear cutting edge position of the rear panel by the first axis 321 and the second axis 322. In this solution, the setting of more than two axes can enable the main board body 1 to perform adaptive movement along the first direction.

[0075] Connecting the main body 1 to the lock of the car tailgate;

[0076] Before performing adaptive adjustment, the lock buckle needs to be fixed on the limiting block 51 first, so that the X and Z positions of the lock buckle are limited by the limiting block 51 .

[0077] The entire main body 1 is fixed to the rear panel of the car tailgate through a magnetic structure.

[0078] After the lock buckle is fixed on the limiting block 51 , the main board body 1 can be finally fixed on the upper end surface of the rear panel through the first magnet member 22 .

[0079] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by utilizing the contents of the present invention's description and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
