Description

Technical Field

[0001] This invention relates to the field of automotive assembly technology, and in particular to a handheld device for controlling the gap between the side panel and the tailgate of an automobile. Background Technology

[0002] As the overall quality level of the automotive industry improves, consumers are now demanding higher standards for vehicle exterior design. The design of the tailgate is becoming increasingly important. The fit between the tailgate exterior trim and the sheet metal is now common practice, and the tolerance requirements for this fit are often quite high, generally needing to be controlled within ±1mm. Since the exterior trim is assembled during final assembly, for the welded body-in-white, it is first necessary to ensure that the gap between the sheet metal on which the tailgate exterior trim is installed and the side panel is within a precise range.

[0003] Existing gap control devices can only monitor the surface difference between the tailgate sheet metal and the side panel. To achieve a qualified surface difference between the tailgate and the side panel, the tailgate often needs to be constantly adjusted, resulting in poor gap control accuracy. Furthermore, the operation process is cumbersome and complex, reducing worker efficiency. Existing gap control devices do not consider the quality defects caused by collisions between the tailgate or side panel and the gap control device. Additionally, different vehicle models often have different requirements for the gap between the tailgate exterior panel and the side panel, and existing gap control devices are often not universally applicable, having a narrow range of applications. Moreover, since tailgate installation takes a long time, the gap control device requires the worker to remain stable throughout the installation process. Existing gap control devices do not consider ease of use for workers or the impact of unstable conditions, making the surface difference control accuracy highly susceptible to human factors and thus poor. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a handheld device for controlling the gap between the side panel and the tailgate of a car.

[0005] A handheld device for controlling the gap between a vehicle side panel and a tailgate according to a first aspect embodiment of the present invention includes:

[0006] The device body has a left mounting portion at one end and a right mounting portion at the other end away from the left mounting portion. The left mounting portion has a first mounting through hole and a second mounting through hole, with a first limiting member fixedly connected to the first mounting through hole and a second limiting member fixedly connected to the second mounting through hole. The right mounting portion has a third mounting through hole and a fourth mounting through hole, with a third limiting member fixedly connected to the third mounting through hole and a fourth limiting member fixedly connected to the fourth mounting through hole. The bottom end of the device body has a fitting portion with an embedded groove, where a magnetic block is installed.

[0007] According to an embodiment of the present invention, a handheld device for controlling the gap between a car side panel and a tailgate, by fixing a first limiting member and a second limiting member to one side of the device body, the first limiting member has one side against the side panel with reference to the side panel, and the other side leaving a preset safety gap with the inner wall of the tailgate, to prevent the tailgate from hitting the first limiting member and causing quality defects. The second limiting member has one side against the tailgate, and the other side leaving a preset safety gap with the side panel, to prevent the side panel from hitting the second limiting member and causing quality defects. The two limiting blocks work together to control the gap tolerance between the side panel end and the tailgate at the side panel corner within the actual required tolerance range. By fixing a third limiting member and a fourth limiting member to one side of the device body, the third limiting member has one side against the side panel with reference to the side panel, and the other side leaving a preset safety gap with the inner wall of the tailgate. The fourth limiting member has one side against the tailgate, and the other side leaving a preset safety gap with the inner wall of the tailgate. A preset safety gap is left between the side and the side panel. Two limiting blocks work together to control the gap tolerance between the top of the side panel corner and the tailgate within the actual required tolerance range. By setting a fitting part on the top of the main body of the device, the shape and structure of the fitting part fits the side panel corner of the actual vehicle model. Several magnetic blocks are set at the bottom of the fitting surface. When the operator operates, they only need to fit the fitting part with the side panel corner to complete the positioning. The device is easy to operate. At the same time, due to the magnetic attraction of the magnetic blocks, the support force when the operator uses the device can be reduced, further reducing the influence of human factors. In addition, pads can be added between the main body of the device and the limiting part to change the gap control between the limiting part and the tailgate. For different vehicle models with different requirements for the gap between the tailgate outer trim panel and the side panel, the gap control handheld device of the present invention is universal and has a wider range of applications.

[0037] Example 1

[0038] Please see Figure 1 and Figure 2 This embodiment provides a handheld device for controlling the gap between the side panel and the tailgate of a car, including:

[0039] The device body 100 has a left mounting portion 110 on one side surface. The left mounting portion 110 has a first mounting through hole 111 and a second mounting through hole 112. Specifically, the first mounting through hole 111 and the second mounting through hole 112 are located on one side of the left mounting portion 110 along the thickness direction. To ensure the stability of the limiting member after installation, three mounting holes 111 are arranged in an array along the vertical direction of the side wall. The first mounting through hole 111 and the second mounting through hole 112 are equal in shape and size and are parallel to each other. The shortest distance between the first mounting through hole 111 and the second mounting through hole 112 is selected according to the width of the limiting member. This arrangement reduces the manufacturing difficulty of the device body 100 while ensuring structural stability.

[0040] A right mounting portion 120 is provided at one end of the device body 100 away from the left mounting portion 110. The right mounting portion 120 has a third mounting through hole 121 and a fourth mounting through hole 122. Specifically, the third mounting through hole 121 and the fourth mounting through hole 122 are located on one side of the right mounting portion 110 along the thickness direction. To ensure the stability of the limiting member after installation, three mounting holes are arranged in an array along the vertical direction of the side wall. The third mounting through hole 121 and the fourth mounting through hole 122 are equal in shape and size and are parallel to each other. The shortest distance between the third mounting through hole 121 and the fourth mounting through hole 122 is selected according to the width of the limiting member. This arrangement reduces the manufacturing difficulty of the device body 100 while ensuring structural stability. It should be noted that the bolt hole size array distribution of the third mounting through hole 121 and the fourth mounting through hole 122 is the same as that of the first mounting through hole 111 and the second mounting through hole 112.

[0041] A first limiting member 300 is fixedly connected to the first mounting through hole 111. Specifically, the first limiting member 300 is fixed to the first mounting through hole 111 by bolts. A second limiting member 400 is fixedly connected to the second mounting through hole 112. Specifically, the second limiting member 400 is fixed to the second mounting through hole 112 by bolts. After the first limiting member 300 and the second limiting member 400 are fixed, they are parallel to each other. A third limiting member 500 is fixedly connected to the third mounting through hole 121. Specifically, the third limiting member 500 is fixed to the third mounting through hole 121 by bolts. A fourth limiting member 600 is fixedly connected to the fourth mounting through hole 122. Specifically, the fourth limiting member 600 is fixed to the fourth mounting through hole 122 by bolts. After the third limiting member 500 and the fourth limiting member 600 are fixed, they are parallel to each other.

[0042] The first limiting member 300 and the second limiting member 400 are fixedly connected to one side of the main body 100 of the device. One side of the first limiting member 300 is against the side wall with reference to the side wall, and the other side has a preset safety gap with the inner wall of the tailgate. In practical applications, this preset safety gap is ±1.5mm to prevent the tailgate from hitting the first limiting member 300 and causing quality defects. One side of the second limiting member 400 is against the tailgate, and the other side has a preset safety gap with the side wall. This preset safety gap is ±1.5mm to prevent the side wall from hitting the second limiting member 400 and causing quality defects. The two limiting blocks are... The clever combination of these two limiting blocks ensures that the gap between the side panel end at the corner and the tailgate is controlled within the required tolerance range. In some embodiments, the required tolerance range can be controlled within ±0.8mm. This is achieved by fixing the third limiting member 500 and the fourth limiting member 600 to one side of the main body of the device. One side of the third limiting member is attached to the side panel with the side panel as a reference, while the other side leaves a preset safety gap with the inner side wall of the tailgate. One side of the fourth limiting member 600 is attached to the tailgate, while the other side leaves a preset safety gap with the side panel. The two limiting blocks work together to ensure that the gap between the top side panel end at the corner and the tailgate is controlled within the required tolerance range.

[0043] The device body 100 has a fitting part 130 at its bottom end. The fitting part 130 has an inner groove 140. In one embodiment, several inner grooves 140 are equidistantly arranged in the fitting part 130. A magnetic block 700 is installed in the inner groove 140. After the magnetic block 700 is installed in the inner groove 140, the bottom surface of the magnetic block 700 is coplanar with the surface of the fitting part 130. It should be noted that the degree of concavity of the fitting part 130 is set according to the shape of the outer corner of the specific vehicle model. When the device is actually used, the fitting part 130 is completely fitted with the side corner. The fitting part 130 is designed to conform to the arc shape of the upper end of the vehicle side. The fitting part 130 includes a first fitting surface 13. The first and second mating surfaces 131 and 132 form an angle that is set according to the side corner angle, which can meet the vehicle body angle range of 105° to 150°, achieving zero-gap fit between the support and sheet metal parts, and achieving precise positioning requirements. By setting the mating part 130 on the top of the main body 100 of the device, the shape and structure of the mating part 130 fits the side corner of the actual vehicle model. Several magnetic blocks 700 are set at the bottom of the mating surface. When the operator operates, the positioning can be completed simply by mating the mating part 130 with the side corner. The device is easy to operate. At the same time, due to the magnetic attraction of the magnetic blocks 700, the support force when the operator uses the device can be reduced, further reducing the influence of human factors.

[0044] A control handle 200 is fixedly connected to the top surface of the main body 100 of the device. The control handle 200 is designed to facilitate the use of the handheld device for controlling the gap between the side panel and the tailgate by the operator. It should also be noted that, in order to reduce the production cost and processing difficulty of the device, the main body 100 of the device is made of nylon material and is manufactured by cutting the nylon material using a CNC machine tool. The control handle 200 is also made of nylon material, which further reduces material costs while meeting structural strength requirements. At the same time, due to the higher strength requirements of the limiting components, the first limiting component 300, the second limiting component 400, the third limiting component 500, and the fourth limiting component 600 are made of carbon steel.

[0045] Example 2

[0046] Please see Figure 3 and Figure 4 This embodiment describes the specific structure of the first limiting member and the second limiting member based on embodiment 1, including:

[0047] The first limiting member 300 includes a first mounting portion 310 and a first limiting portion 320, with the first limiting portion 320 disposed at one end of the first mounting portion 310; the second limiting member 400 includes a second mounting portion 410 and a second limiting portion 420, with the second limiting portion 420 disposed at one end of the second mounting portion 410; the front end face of the first limiting portion 320 is provided with a first contact surface 321 and a first limiting main surface 322; the first contact surface 321 and the first limiting main surface 322 are transitionally connected; the front end face of the second limiting portion 400 is provided with a second contact surface 421 and a second limiting main surface 422; the second contact surface 421 and the second limiting main surface 422 are transitionally connected;

[0048] The first mounting portion 310 and the second mounting portion 410 facilitate the installation and fixation of the first limiting member 300 and the second limiting member 400 on the device body 100. By providing the first contact surface 321 and the first limiting main surface 322 in the first limiting portion 320, and the second contact surface 421 and the second limiting main surface 422 in the second limiting portion 420, the gap difference range between the side wall and the tailgate can be accurately controlled after the first limiting member 300 and the second limiting member 400 are installed.

[0049] The first contact surface 321 and the second contact surface 421 are coplanar, the first limiting main surface 322 and the second limiting main surface 422 are coplanar, the rear end face of the first limiting part 320 is provided with a first limiting secondary surface 323, and the rear end face of the second limiting part 420 is provided with a first transition surface 423 and a second limiting secondary surface 424; the first transition surface 423 and the second limiting secondary surface 424 are transitionally connected, and the first limiting secondary surface 323 and the second limiting secondary surface 424 are coplanar.

[0050] By having the first contact surface 321 and the second contact surface 421 coplanarly arranged, the first limiting member 300 and the second limiting member 400 fit precisely against one side of the side panel, thereby maintaining a set gap difference between the first limiting main surface 322 and the second limiting main surface 422 and the side panel. When installing the tailgate, the gap tolerance between the side panel and the tailgate is accurately controlled. By having the first limiting secondary surface 323 and the second limiting secondary surface 424 coplanarly arranged, the first limiting member 300 and the second limiting member 400 accurately control the gap tolerance between the side panel and the tailgate.

[0051] Example 3

[0052] Please see Figure 5 and Figure 6 This embodiment describes the specific structure of the third and fourth limiting members based on embodiment 1, including:

[0053] The third limiting member 500 includes a third mounting portion 510 and a third limiting portion 520, with the third limiting portion 520 disposed at one end of the third mounting portion 510; the fourth limiting member 600 includes a fourth mounting portion 610 and a fourth limiting portion 620, with the fourth limiting portion 620 disposed at one end of the fourth mounting portion 610.

[0054] The front end face of the third limiting part 520 is provided with a first cut surface 521 and a second cut surface 522; the first cut surface 521 and the second cut surface 522 are connected in transition; the front end face of the fourth limiting part 620 is provided with a third cut surface 621.

[0055] The third mounting part 510 and the fourth mounting part 610 facilitate the installation and fixation of the third limiting member 500 and the fourth limiting member 600 on the device body 100. By providing the first cutting surface 521 and the second cutting surface 522 on the third limiting part 500 and the third cutting surface 621 on the fourth limiting part 620, the gap between the top of the side panel and the tailgate is different from the gap between the side panel and the tailgate. Therefore, by providing the first cutting surface 521, the second cutting surface 522 and the third cutting surface 621, the gap difference range between the side panel and the tailgate can be accurately controlled after the third limiting member 500 and the fourth limiting member 600 are installed.

[0056] The second cut surface 522 is coplanar with the third cut surface 621. The rear end face of the third limiting part 520 is provided with a second transition cut surface 523 and a third limiting secondary surface 524. The second transition cut surface 523 and the third limiting secondary surface 524 are transitionally connected. The rear end face of the fourth limiting part 610 is provided with a fourth limiting secondary surface 622. The third limiting secondary surface 524 is coplanar with the fourth limiting secondary surface 622.

[0057] By having the second cut surface 522 and the third cut surface 621 coplanarly arranged, the third limiting member 500 and the fourth limiting member 600 are made to fit snugly against one side of the side panel, thereby maintaining a set gap difference between the third limiting member 500 and the fourth limiting member 600 and the side panel. When installing the tailgate, the gap tolerance between the side panel and the tailgate is accurately controlled. By having the third limiting secondary surface 524 and the fourth limiting secondary surface 610 coplanarly arranged, the third limiting member 500 and the fourth limiting member 600 are made to accurately control the gap tolerance between the side panel and the tailgate.

[0058] Example 3

[0059] Please see Figure 7 and Figure 8 This embodiment describes the specific structure and usage of the limiting gasket based on Embodiment 1, including:

[0060] A limiting washer 800 is a rectangular block. The limiting washer 800 has mounting holes 810 along its thickness direction. Specifically, the mounting holes 810 are arrayed bolt holes, the number of which is the same as the number of bolt holes in the limiting component mounting part. The diameter of the bolt holes on the limiting washer 800 is the same as the diameter of the bolt holes in the limiting component mounting part. In some embodiments, the thickness of the limiting washer 800 is an integer millimeter, specifically 1mm or 2mm. In use, such as... Figure 8As shown, the limiting shim 800 is aligned with the first limiting member 300 and then fixed to the device body 100 with bolts. It should be noted that the second limiting member 400, the third limiting member 500 and the fourth limiting member 600 also need to have an equal number of limiting shims 800 added at the connection of the device body 100 to ensure that the limiting member controls the clearance tolerance between the side panel and the tailgate. By setting the limiting shims 800, the clearance control between the side panel and the tailgate of the limiting member is changed, which can adapt to the different requirements of the clearance between the tailgate outer trim panel and the side panel of different vehicle models, so that the clearance control handheld device of the present invention has a wider range of applications.
