[0040] Please refer to Figures 1 to 3 , this application provides a vehicle gap adjustment device 100 for adjusting the installation position of the front door according to the gap between the front door (not shown) and the fender (not shown) of the vehicle. During the assembly process of the vehicle, the vehicle gap adjustment device 100 is first installed on the vehicle body frame, and then the front door is mounted on the vehicle gap adjustment device 100. The position of the front door is adjusted according to the required gap between the front door and the fender. After the position of the front door is adjusted, the front door is fixed on the vehicle body frame.
[0041] The vehicle gap adjustment device 100 includes a base 10, and a positioning component 20, a fender profiling component 30, and an adjustment component 40 disposed on the base 10. In this embodiment, a handrail 50 is provided on the base 10, and by providing the handrail 50, it is convenient to install the vehicle gap adjustment device 100 on the vehicle body frame. The positioning component 20 is used to connect with the vehicle body frame to define the position of the vehicle gap adjustment device 100 on the vehicle body frame. After the fender profiling component 30 is installed on the vehicle body frame, it is used to simulate the position of the fender. After the vehicle gap adjustment device is installed on the vehicle body frame, the adjustment component 40 is used to mount the door hinge of the front door. During vehicle assembly, after the door hinge of the front door is mounted on the adjustment component 40 and before the position of the front door is moved to the pre-installed position, the door hinge can slide on the adjustment component 40 along the length direction of the vehicle to adjust the positional relationship between the front door and the fender profiling component 30. The relative position of the adjustment component 40 and the door hinge in the length direction of the vehicle defines the relative position between the front door and the fender profiling component 30, and this relative position determines the gap between the fender and the front door. Figure 1 The direction indicated by the arrows a1 - a2 in the figure is the length direction of the vehicle.
[0042] By mounting the door hinge of the front door on the adjustment component 40, the front door is first positioned on the vehicle body frame in the height direction ( Figure 1 the direction indicated by the arrows b1 - b2 in the figure). By simulating the position of the fender with the fender profiling component 30 to adjust the relative position between the front door and it, it is possible to adjust the pre-installed position of the front door according to the positional relationship between the front door and the fender before the front door is installed, so as to avoid the problem of excessive gap between the front door and the fender caused by tolerance accumulation, improve the vehicle appearance quality, and also solve the problem of unstable fender assembly caused by the need to match the gap between the front door and the fender during the process of adjusting the fender after the front door is installed; and, after adjusting the pre-installed position of the front door through the vehicle gap adjustment device 100, it helps to reduce the rework of the front door and improve the vehicle assembly efficiency.
[0043] It should be noted that after the front door is mounted on the adjustment component 40, when the front door adjusts its position in the length direction a1 - a2 of the vehicle, a gap adjustment piece (not shown) will be inserted between the front door and the fender profiling component 30 to ensure the gap between the front door and the fender profiling component 30, and the thickness of this gap adjustment piece is the required gap between the front door and the fender.
[0044] In this embodiment, the positioning assembly 20 includes a positioning hook pin 21, a positioning block 22, and a hook 23 provided on the base 10. The positioning hook pin 21 is used to be clamped in the side wall positioning hole of the vehicle body frame, the positioning block 22 is used to abut against the side wall of the vehicle body frame, and the hook 23 is used to be clamped in the lock mounting groove of the vehicle body frame. The vehicle gap adjusting device 100 is installed on the vehicle body frame through the positioning hook pin 21, the positioning block 22, and the hook 23. The fixing is simple and easy to operate. Moreover, the positioning hook pin 21, the positioning block 22, and the hook 23 adopt structures such as the side wall positioning holes existing in the vehicle body frame itself, and will not damage the vehicle frame. The positioning hook pin 21 can adopt the structure of a movable hook pin in the prior art. The positioning hook pin 21 generally has a hook portion 211 inserted into the side wall positioning hole and an operating portion 212 for driving the hook portion 211 to expand or fold. When the hook portion 211 is in the expanded state, the hook portion 211 is locked in the side wall positioning hole. When the hook portion 211 is in the folded state, the hook portion 211 is not locked in the side wall positioning hole. In this way, the hook portion 211 can be removed or inserted into the side wall positioning hole.
[0045] In this embodiment, the fender profiling assembly 30 includes an extension plate 31 installed on the base 10, a fender profiling block 32 detachably installed on the extension plate 31, and an adjustment gasket 33 clamped between the extension plate 31 and the fender profiling block 32. The fender profiling block 32 can move relative to the extension plate 31 along the length direction a1-a2 of the vehicle. Specifically, the fender profiling block 32 has an L-shaped structure and includes a first block portion 321 and a second block portion 322. The end face of the first block portion 321 simulates the side face of the fender. During vehicle assembly, the end face of the first block portion 321 faces the side plate of the front door, and a gap adjustment sheet is inserted therebetween. The extension plate 31 has an L-shaped structure and includes an extension arm 311 fixed to the base 10 on one side and a mounting portion 312 bent from the other end of the extension arm 311. The adjustment gasket 33 is clamped between the second block portion 322 and the mounting portion 312. Through holes (not labeled) are formed in the second block portion 322, the adjustment gasket 33, and the mounting portion 312. Fasteners (not labeled) sequentially pass through the through holes in the second block portion 322, the adjustment gasket 33, and the mounting portion 312 to fix the fender profiling block 32 and the adjustment gasket 33 on the extension plate 31. The adjustment gasket 33 can be composed of multiple sub-gaskets. By detachably installing the fender profiling block 32 on the extension plate 31, the position of the fender profiling block 32 on the extension plate 31 can be adjusted according to different gap requirements. In this way, the applicability of the vehicle gap adjusting device 100 is improved.
[0046] In another embodiment, the adjusting gasket 33 may not be provided, and the fender profiling block 32 may be directly fixed to the extension plate 31. The fender profiling block 32 may include a plurality of different length dimensions. During vehicle assembly, the corresponding fender profiling block 32 may be selected according to the pre-installed position of the fender. In other embodiments, the position of the fender profiling block 32 relative to the extension plate 31 may also be adjusted by an adjusting structure. For example, a screw rod that can rotate but is axially restricted from moving is provided on the extension plate 31, and the fender profiling block 32 is threadedly installed on the screw rod. In this way, the position of the fender profiling block 32 relative to the extension plate 31 is adjusted by rotating the screw rod. Compared with the above embodiments, in this embodiment, since the thickness of the adjusting gasket 33 is easy to control, by providing the adjusting gasket 33 between the extension plate 31 and the fender profiling block 32 to control the position of the fender profiling block 32, the position adjustment of the fender profiling block 32 is simple and reliable.
[0047] In this embodiment, the adjusting assembly 40 includes a carrying block 41 and a rolling member 42 provided on the carrying block 41. A rolling cavity (not labeled) for accommodating the rolling member 42 is formed on the carrying block 41. The rolling member 42 protrudes from the carrying block 41 in the height direction b1 - b2 of the vehicle, and the height direction b1 - b2 of the vehicle is opposite to the installation direction in which the door hinge is installed on the adjusting assembly 40. By providing the rolling member 42 on the carrier, when the door hinge is installed on the adjusting assembly 40, the door hinge and the positioning assembly 20 are in rolling contact, reducing the friction force, so as to facilitate the position adjustment of the door hinge in the length direction a1 - a2 of the vehicle. In one embodiment, the rolling member 42 is a roller, and the roller rolls along the length direction a1 - a2 of the vehicle. The rolling member 42 is fixed in the rolling cavity through a mounting shaft (not shown). By setting the rolling member 42 as a roller, it is defined that the front door can only move in the length direction a1 - a2 of the vehicle, which helps to prevent the front door from shifting in other directions when the front door moves. In another embodiment, the rolling member 42 may also be a ball, and the number of the rolling members 42 may be one or more.
[0048] The carrying block 41 has a base portion 411 fixed to the base 10 and a plug portion 412 extending along the height direction b1 - b2 of the vehicle from the base portion 411. The plug portion 412 is used to be inserted into the door hinge, and the rolling cavity is formed on the plug portion 412. By forming the plug portion 412 that can be inserted into the door hinge, when the front door moves on the adjusting assembly 40, the door hinge and the adjusting assembly 40 can be prevented from detaching, strengthening the stability during the adjustment of the front door.
[0049] After the front door is mounted on the vehicle gap adjusting device 100, it may be in the width direction of the vehicle ( Figure 1A slight movement occurs in the direction indicated by the arrow c1-c2. To solve this problem, the vehicle gap adjustment device in this embodiment further includes a buffer block 60 and a pressing block 70. The buffer block 60 extends along the length direction a1-a2 of the vehicle and is used to abut against the side plate of the front door. By means of the buffer block 60, it can abut against the side plate of the front door during vehicle assembly to ensure the positioning of the adjusted door in the length direction a1-a2 of the vehicle. The pressing block 70 moves along the width direction c1-c2 of the vehicle and is used to abut against the outer end face of the front door. The width direction c1-c2 of the vehicle is the direction in which the front door moves towards the vehicle body frame. By means of the buffer block 60, it can abut against the outer end face of the front door during vehicle assembly to ensure the positioning of the adjusted door in the width direction c1-c2 of the vehicle. The buffer block 60 and the pressing block 70 are respectively driven by a first operating handle 61 and a second operating handle 71, so that they can move relative to the front door. The ways in which the first operating handle 61 and the second operating handle 71 drive the buffer block 60 and the pressing block 70 respectively can adopt the connection driving ways in the prior art and will not be elaborated here. Elastic materials such as sponges are provided on both the buffer block 60 and the pressing block 70. In this way, the rigid impact when the buffer block 60 and the pressing block 70 abut against the front door can be avoided.
[0050] It should be noted that when the front door is not adjusted to the pre-installed position, there is an adjustment gap for the displacement of the front door between the buffer block 60 and the pressing block 70 and the front door. After the front door is adjusted to the pre-installed position, the buffer block 60 and the pressing block 70 abut against the front door. In other embodiments, only one of the buffer block 60 and the pressing block 70 can be provided. However, setting both helps to limit the adjusted door simultaneously in the length direction a1-a2 of the vehicle and the width direction c1-c2 of the vehicle, and can ensure that the door is misaligned during the adjustment process.
[0051] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered as the scope described in this specification.
[0052] The above embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
