Description

Technical Field

[0001] The utility model relates to the technical field of automobile part assembly, and more specifically, to a latch adjustment tool. Background Technique

[0002] At present, in China, with the increasing demand for MPVs in the automotive market, more and more vehicles adopt sliding door structures. Compared with ordinary hinged side doors, sliding doors have the advantages of large opening, small external space occupied after opening, convenient boarding and parking. However, due to the complex assembly process and functional characteristics of the sliding door system, the appearance matching quality between the sliding door and the body has always been a manufacturing difficulty for each vehicle manufacturer. Problems such as the collision between the sliding door lock and the rear latch due to fluctuations in the assembly accuracy of the sliding door are likely to occur, resulting in some quality and commerciality problems such as the sliding door rollers leaving the air guide rail. When there is a problem of collision between the rear lock and the latch of the sliding door, it is necessary to loosen the rear latch nut, use a hammer to tap the latch up and down for adjustment, then tighten the nut and close the door to confirm whether there is a collision to solve the collision problem. For serious collisions, it is necessary to repair and adjust the position of the middle hinge offline to control the Z-directional position of the sliding door. The assembly process of the sliding door is complex, the dimension chain is relatively long, and affected by the accumulation of part tolerances and assembly fluctuations, there is likely to be Z-direction interference between the rear latch of the sliding door and the lock. Since the Y-direction spacing between the sliding door and the side wall is insufficient after the sliding door is opened, there is insufficient effective space when adjusting and loosening the latch nut, and there is a lack of effective tools to loosen and tighten the nut, resulting in too long adjustment working hours, about 50 seconds. The production line beat is 65 seconds, resulting in the need to add 2 additional personnel and positions for operation, otherwise there is a risk of line stop. When loosening the nut to adjust the latch and tapping up and down, the employee cannot accurately control the adjustment amount, resulting in the situation that sometimes the adjustment amount is too large or too small to meet the one-time adjustment requirement, and there is a waste of working hours due to repeated adjustments. After loosening the nut, only the Z-direction collision problem can be adjusted, and the Y-plane step difference between the sliding door and the side wall cannot be adjusted at the same time.

[0003] There is a prior Chinese utility model with an application number of CN202120502105.2, which discloses a door adjustment tool, including: a handle, a hammer head, a latch adjustment assembly, and a screwdriver assembly; the hammer head is installed at one end of the handle; the latch adjustment assembly includes a handle body installed at the other end of the handle, and a head body installed on the handle body, and the overall structure between the handle body and the head body is in a "7" shape, and the head body is used for cooperative connection with the door latch; the screwdriver assembly is hinged to the handle body. This tool can effectively reduce the labor intensity and prevent the occurrence of secondary defects, achieve the purpose of quickly replacing the adjustment tool to be used, effectively solve the limitations and cumbersome nature of the use of the adjustment tool, improve the convenience and efficiency during adjustment, and ensure the quality stability after the door is adjusted.

[0004] In the above technical solution, since the buckle adjustment component is directly connected to the handle, and the handle and the adjustment component are in a straight line, when adjusting, the handle, the adjustment component and the buckle are in a straight line, and the space opposite to the buckle is the door space. Therefore, this technical solution can only adjust the door buckle whose door width is longer than the handle length, and is not applicable to the use scenario of adjusting the door buckle in a narrow space. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a buckle adjustment tool, which can adjust the position fluctuation of the buckle in the Z direction and the position degree of the buckle in the Y direction, and by setting a certain angle between the buckle adjustment end and the force-bearing rod, the force-bearing rod occupies a smaller space without shortening, and is suitable for the use scenario of adjusting the door buckle in a more narrow space.

[0006] To solve the above technical problems, the present invention provides a buckle adjustment tool, including a force-bearing rod and a buckle adjustment end that can be inserted into the buckle. One end of the buckle adjustment end is connected to one end of the force-bearing rod, and an acute angle is formed between the surface of the buckle adjustment end connected to the force-bearing rod and the end surface of the force-bearing rod.

[0007] In the present technical solution, when the position of the door lock buckle needs to be adjusted, the lock buckle adjustment end is inserted into the lock buckle. The user holds the force rod with both hands, wherein the hand close to the lock buckle adjustment end holds the force rod as the fulcrum, and the hand far away from the lock buckle adjustment end holds the force rod as the force application point. The contact point between the lock buckle adjustment end and the lock buckle is the force point. The fulcrum, the force application point and the force application point together constitute a simple lever structure. The user can pry the lock buckle to move it in different directions by applying forces in different directions at the force application point. In this process, there is no need to loosen the bolts fixing the door lock buckle. The force applied to the lock buckle by the force rod causes a certain amount of deformation of the lock buckle, thereby causing the lock buckle position to move, and an adjustment amount of 2 to 3 mm can be achieved, which greatly saves the time required for adjusting the lock buckle position. Only a single worker is needed to quickly complete the lock buckle position adjustment and meet the production rhythm of the production line, avoiding the situation where the production line is stopped due to the long lock buckle adjustment time, and reducing the number of workers required. The positions of the force-bearing point and the force-applying point can be flexibly adjusted by the operator holding the force-bearing rod in different positions according to actual needs, which has the advantages of simple operation, time saving and labor saving. When it is necessary to adjust the Y-axis position of the lock buckle to the left or right horizontally, the lock buckle adjustment end is inserted into the lock buckle, and the user holds the force-bearing rod with both hands and applies force in the opposite direction of the direction in which the lock buckle needs to move at the force-applying point. Under the action of the force, the force-bearing rod rotates around the fulcrum, and the force-bearing rod drives the lock buckle adjustment end to move, pushing the lock buckle to move. When it is necessary to adjust the Z-axis position of the lock buckle in the vertical direction, it is necessary to insert the lock buckle adjustment end into the lock buckle in different directions according to the different adjustment directions to ensure that the lock buckle can contact the force-bearing rod to withstand the force transmitted by the force-bearing rod. When it is necessary to move the lock buckle downward, it is necessary to insert the lock buckle adjustment end into the lock buckle from top to bottom. When it is necessary to move the closing upward, it is necessary to insert the lock buckle adjustment end into the lock buckle from bottom to top. The car door lock is installed in the door frame where the door is located, so the installation and adjustment space of the door lock is limited by the size of the door frame and the position of the door. The side of the lock adjustment end close to the force-bearing rod forms a certain angle with the end face of the force-bearing rod, so that the lock adjustment end is tilted at a certain angle compared to the force-bearing rod. When in use, since the lock adjustment end needs to be inserted into the lock, the position of the lock adjustment end cannot be changed. However, by setting a certain angle between the force-bearing rod and the lock adjustment end to form an acute angle, the force-bearing rod is tilted in the inner direction of the vehicle body, and is no longer limited by the door and the door frame, and can be used in the use scenario of the door lock adjustment in a narrow space.

[0008] Preferably, the lock adjustment end includes a first body and a second body, the second body is connected to one end of the force-bearing rod, the first body is installed on the second body, and the length direction of the first body is perpendicular to the length direction of the force-bearing rod.

[0009] Preferably, the first body is a conical structure with a gradually decreasing cross-sectional area in the direction away from the force-bearing rod.

[0010] Preferably, one side of the first body away from the force-bearing rod is an inclined surface, and the inclined surface slopes in the direction of the force-bearing rod starting from the connection with the second body.

[0011] Preferably, it further includes an inclined side surface. The two sides of the inclined surface are connected to the two inclined side surfaces, and the angle between the inclined surface and the inclined side surface is an obtuse angle.

[0012] Preferably, on the side of the second body away from the force-bearing rod, there is a second inclined surface that slopes in the direction of the force-bearing rod from the side close to the first body.

[0013] Preferably, it further includes a second inclined side surface. The two sides on the second inclined surface are respectively connected to the two second inclined side surfaces, and the angle between the second inclined surface and the second inclined side surface is an obtuse angle.

[0014] Preferably, a reinforcing rib is provided at the connection between the second body and the force-bearing rod.

[0015] Preferably, a second lock adjustment end is further provided at the other end of the force-bearing rod.

[0016] Preferably, the second lock adjustment end has the same structure as the lock adjustment end, and the second lock adjustment end and the lock adjustment end are mirror-symmetrical with the mid-perpendicular plane of the force-bearing rod as the mirror surface.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: A certain angle is set between the lock adjustment end and the force-bearing rod, so that the force-bearing rod occupies a smaller space without shortening, adapting to the use scenario of door lock adjustment in a narrower space. The position of the lock can be adjusted directly by prying the lock to cause deformation of the lock, without loosening the bolts fixing the lock, saving the adjustment time and improving the adjustment efficiency. The significant component in the lock adjustment end is a conical structure, which is easy to insert into the lock. The first inclined surface and the second inclined surface are provided on the lock adjustment end, ensuring that when adjusting the Z-direction position of the lock in the vertical direction, the lock adjustment end can contact the lock on the first inclined surface or the second inclined surface, increasing the contact area and avoiding damage to the surface of the lock. The inclined side surface and the second inclined side surface are provided to avoid damage to the surface of the lock caused by the overly sharp side edges of the lock adjustment end when adjusting the position of the lock. A second lock matching end is further provided at the other end of the force-bearing rod, which can simultaneously adapt to the lock adjustment working scenarios of the left and right doors of the vehicle.

[0022] The technical solutions of the present utility model will be further specifically described below through specific embodiments and in combination with the attached drawings:

[0023] Embodiment 1

[0024] As Figure 1As shown, a lock adjustment tool comprises a force rod 1 and a lock adjustment end 2 which can be inserted into a lock 4, one end of the lock adjustment end 2 is connected to one end of the force rod 1, and an acute angle is formed between the side of the lock adjustment end 2 connected to the force rod 1 and the end face of the force rod 1. When the position of the door lock 4 needs to be adjusted, the lock adjustment end 2 is inserted into the lock 4. The user holds the force rod 1 with both hands, wherein the hand close to the lock adjustment end 2 holds the force rod 1 as a fulcrum, and the hand away from the lock adjustment end 2 holds the force rod 1 as a force application point, and the contact point between the lock adjustment end 2 and the lock 4 is the force point, and the fulcrum, the force application point and the force point together constitute a simple lever structure, and the user can pry the lock 4 to move it in different directions by applying forces in different directions at the force application point. In this process, it is not necessary to loosen the bolts fixing the door lock 4. The force applied to the lock 4 by the force rod 1 causes a certain amount of deformation of the lock 4, thereby causing the position of the lock 4 to move, and an adjustment of 2 to 3 mm can be achieved, which greatly saves the time required for the position adjustment of the lock 4. Only a single worker is needed to quickly complete the position adjustment of the lock 4 and meet the production rhythm of the production line, avoiding the situation where the production line is stopped due to the long adjustment time of the lock 4, and reducing the number of workers required. The position of the force point and the force application point can be flexibly adjusted by the operator holding the force rod 1 at different positions according to actual needs, which has the advantages of simple operation, time saving and labor saving. When the Y-axis position of the lock 4 needs to be adjusted horizontally to the left or right, the lock adjustment end 2 is inserted into the lock 4, and the user holds the force rod 1 with both hands and applies force in the opposite direction of the direction in which the lock 4 needs to move at the force application point. Under the action of the force, the force rod 1 rotates around the fulcrum, and the force rod 1 drives the lock adjustment end 2 to move, pushing the lock 4 to move. When it is necessary to adjust the Z-direction position of the lock buckle 4 in the vertical direction, the lock buckle adjustment end 2 needs to be inserted into the lock buckle 4 in different directions according to the different adjustment directions to ensure that the lock buckle 4 can contact the force-bearing rod 1 to withstand the force transmitted by the force-bearing rod 1. When it is necessary to move the lock buckle 4 downward, the lock buckle adjustment end 2 needs to be inserted into the lock buckle 4 from top to bottom. When it is necessary to move the closing upward, the lock buckle adjustment end 2 needs to be inserted into the lock buckle 4 from bottom to top. The car door lock buckle 4 is installed in the door frame where the car door is located, so the installation and adjustment space for the car door lock buckle 4 is limited by the size of the door frame and the position of the car door. The side of the lock buckle adjustment end 2 close to the force-bearing rod 1 forms a certain angle with the end face of the force-bearing rod 1, so that the lock buckle adjustment end 2 is tilted at a certain angle compared to the force-bearing rod 1. When in use, since the lock buckle adjustment end 2 needs to be inserted into the lock buckle 4, the position of the lock buckle adjustment end 2 cannot be changed. However, by setting a certain angle between the stress rod 1 and the lock adjustment end 2 to form an acute angle, the stress rod 1 is tilted toward the inside of the vehicle body and is no longer restricted by the door and the door frame, so it can be used in the use scenario of adjusting the door lock 4 in a narrow space.

[0025] likeFigure 1 As shown, the buckle adjustment end 2 includes a first body 22 and a second body 23. The second body 23 is connected to one end of the force-receiving rod 1. The first body 22 is mounted on the second body 23, and the length direction of the first body 22 is perpendicular to the length direction of the force-receiving rod 1. The first body 22 is used to insert into the buckle 4 and apply a force to the buckle 4, and the second body 23 is used to connect with the force-receiving rod 1.

[0026] As Figure 1 shown, the first body 22 is a conical structure with a gradually decreasing cross-sectional area in the direction away from the force-receiving rod 1. During use, the end face of the first body 22 away from the force-receiving rod first inserts into the buckle 4. When inserting into the buckle 4, it is necessary for the cross-section of the first body 22 to be as small as possible to make it easier to insert into the buckle. When adjusting the position of the buckle 4, the cross-section of the first body 22 should fill the buckle 4 as much as possible to prevent the buckle matching end 2 from deflecting within the buckle 4. Setting the first body 22 as a conical structure enables the first body 22 to be easily inserted into the buckle 4 and, at the same time, when adjusting the position of the buckle 4, the first body 22 can fill the space of the buckle 4 as much as possible, ensuring that the first body 22 can have the largest possible contact area with the buckle 4 when adjusting the buckle 4.

[0027] As Figure 1 shown, one side surface of the first body 22 away from the force-receiving rod 1 is an inclined surface 221, and the inclined surface 221 slopes towards the direction of the force-receiving rod 1 starting from the connection with the second body 23. One side surface of the first body 22 away from the force-receiving rod 1 being an inclined surface 221 makes the first body 22 a conical structure, which is easy to insert into the buckle 4. At the same time, if the side in contact between the buckle adjustment end 2 and the buckle 4 is a right angle edge, when the buckle adjustment end 2 applies a rotational torque to the buckle 4, the force will be concentrated on the edge line where the buckle adjustment end 2 contacts the buckle 4, which is easy to damage the surface of the buckle 4. Setting one side surface of the first body 22 away from the force-receiving rod 1 as the inclined surface 221 enables the inclined surface 221 to fit the buckle 4 when the buckle adjustment end 2 applies a rotational torque to the buckle 4, dispersing the force originally concentrated on the edge line and avoiding damaging the surface of the buckle 4.

[0028] As Figure 1 shown, it further includes an inclined side surface 222. The two side edges of the inclined surface 221 are connected to the two inclined side surfaces 222, and the included angle between the inclined surface 221 and the inclined side surfaces 222 is an obtuse angle. The two side edges of the first body 22 away from the force-receiving rod 1 are prone to collide with the buckle 4 during the insertion process, and the overly sharp side edges are easy to scratch the surface of the buckle 4. Changing the two side edges of the first body 21 away from the force-receiving rod 1 into two inclined side surfaces 222 avoids scratching the surface of the buckle 4.

[0029] Embodiment 2

[0030] This embodiment is similar to the above-mentioned Embodiment 1, except that, as Figure 1 shown, on the side of the second body 23 away from the force-bearing rod 1, there is a second inclined surface 231 that slopes from the side closer to the first body 23 towards the direction where the force-bearing rod 1 is located. A fixing structure for connecting with the vehicle body 5 is also provided on the latch 4, and the bolt occupies a certain space of the closing opening 4. Although the second body 23 does not need to be inserted into the latch 4, it will still occupy the space near the latch 4, which may cause the second body 23 to conflict with the fixing structure on the latch 4. Therefore, the side of the second body 23 away from the force-bearing rod 1 is set as the second inclined surface 231, which reduces the space occupied by the second body 23 while not affecting the connection effect with the force-bearing rod 1 and the first body 22, ensuring that the second body 23 will not conflict with the fixing structure on the latch 4.

[0031] As Figure 1 shown, it further includes second inclined side surfaces 232. The two side edges on the second inclined surface 231 are respectively connected to the two second inclined side surfaces 232, and the included angle between the second inclined surface 231 and the second inclined side surfaces 232 is an obtuse angle. The two side edges on the second inclined surface 231 are relatively sharp and may scratch the surface of the latch 4. Replacing the two side edges on the second inclined surface 231 with the two second inclined side surfaces 232 can avoid scratching the surface of the latch 4.

[0032] As Figure 1 shown, a reinforcing rib 21 is provided at the connection part of the second body 23 and the force-bearing rod 1. During use, the connection part between the second body 23 and the force-bearing rod 1 needs to bear a large load. Also, since the surface of the latch adjustment end 2 close to the force-bearing rod forms an acute angle with the end face of the force-bearing rod 1, the connection between the second body 23 and the force-bearing rod 1 is a special-shaped connection and is prone to breakage at the connection due to excessive load. Therefore, a reinforcing rib 21 is provided at the connection part of the second body 23 and the force-bearing rod 1, ensuring the structural strength of the connection part between the second body 23 and the force-bearing rod 1 and not being easily broken.

[0033] Embodiment 3

[0034] This embodiment is similar to the above-mentioned Embodiment 1, except that, as Figure 1 shown, a second latch matching end 3 is further provided at the other end of the force-bearing rod 1. Since the surface of the latch adjustment end 2 close to the force-bearing rod forms a certain angle with the end face of the force-bearing rod 1, the force-bearing rod 1 has a direction. When adjusting the left vehicle door latch 4, the force-bearing rod 1 inclines towards the inside of the vehicle. When adjusting the right vehicle door latch, if the same latch adjustment end 2 is used, the inclination direction of the force-bearing rod 1 changes from inclining towards the inside of the vehicle to inclining towards the outside of the vehicle. Therefore, it is necessary to set the second latch matching end 3 for matching the adjustment of the vehicle door latches 4 in different directions.

[0035] As Figure 1As shown, the second latch matching end 3 has the same structure as the latch matching end 2. The second latch matching end 3 and the latch matching end 2 are mirror-symmetrical with the middle vertical plane of the force-bearing rod 1 as the mirror surface. When in use, whether adjusting the latch 4 of the left door or the right door of the vehicle, the inclination of the force-bearing rod 1 towards the interior of the vehicle can be ensured by replacing the latch matching end 2 or the second latch matching end 3.

[0036] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
