[0033] In this embodiment, to reduce the machining accuracy of the first connector 31, the insertion hole on the fender that mates with the first connector 31 is a long hole extending along the first direction. When the first connector 31 is engaged with the insertion hole on the fender, the hood installation and positioning tooling can achieve precise positioning with respect to the vehicle body along the vehicle body length and height directions, as well as coarse positioning along the first direction (the vehicle body width direction). Furthermore, when the two first connectors 31 are positioned and engaged with the two fenders, the two stoppers 32 respectively abut against the opposing end surfaces of the two fenders along the first direction, achieving precise positioning of the hood installation and positioning tooling with respect to the vehicle body along the first direction (the vehicle body width direction).

[0035] In addition, the hood installation and positioning tooling also includes a first support assembly and a second support assembly. The first support assembly is arranged on the fixed seat 10 and is used to support the vehicle body to assist the first positioning assembly in positioning the hood installation and positioning tooling; the second support assembly is arranged on the movable seat 20 and is used to support the hood to assist the second positioning assembly in positioning the hood. In this embodiment, the first support assembly includes two first support members 51, and the two first support members 51 are spaced apart along the first direction. Of course, the number of first support members 51 can be more than two and is not limited to this embodiment. The second support assembly includes two second support members 52 and two third support members 53, and the two second support members 52 and the two third support members 53 are spaced apart along the first direction, and the second support members 52 and the third support members 53 are spaced apart along the length direction of the vehicle body.

Of course, the number of second support members 52 and the third support members 53 can also be more than two and is not limited to this embodiment.

[0036] When installing the hood, first, the two first connectors 31 in the hood installation and positioning tool are respectively plugged into the plug holes on the two fenders one by one, so as to realize the precise positioning of the hood installation and positioning tool and the vehicle body along the length direction and the height direction of the vehicle body, as well as the rough positioning along the first direction (the width direction of the vehicle body); in the process of the two first connectors 31 being plugged into the two fenders one by one, the movable seat 20 is adjusted at the same time, so that the position of the movable seat 20 is fine-tuned relative to the fixed seat 10 along the first direction, so that after the first connector 31 is plugged into the fender, the two limit members 32 can respectively engage with the two opposite fenders along the first direction. The end faces are abutted one by one to achieve precise positioning of the hood installation and positioning tooling and the vehicle body along the first direction; then at least two first connectors 31 are respectively plugged into the two fenders, and the two limiting members 32 are respectively abutted one by one with the two end faces opposite to each other along the first direction of the two fenders, while the first support member 51 is supported on the vehicle body; then the hood is positioned and plugged into the second connector 41 in the hood installation and positioning tooling, while the second support member 52 and the third support member 53 are supported on the hood to achieve positioning of the hood and the hood installation and positioning tooling; after the hood is positioned, the hood is installed and tightened; finally, the hood installation and positioning tooling is removed from the vehicle body. By setting a fixed seat 10 and a movable seat 20, and enabling the movable seat 20 to slide relative to the fixed seat 10, and enabling the limiting member 32 in the first positioning assembly to be set on the movable seat 20, precise positioning can be achieved by moving the movable seat 20 during the positioning of the hood installation and positioning tooling and the vehicle body, thereby reducing the processing accuracy requirements of the first positioning assembly and thus reducing the processing difficulty of the first positioning assembly.

[0037] Furthermore, the cover installation and positioning tool also includes an adjustment mechanism 60, which is used to adjust the direction and amount of movement of the movable seat 20 relative to the fixed seat 10.

[0038] In this embodiment, the adjustment mechanism 60 includes a housing 61, a rotating member 62, a moving member 64 and a driving member 63. The housing 61 is arranged on the fixed base 10, the rotating member 62 is rotatably connected to the housing 61, the axis of the rotating member 62 is parallel to the first direction, the moving member 64 is arranged on the moving base 20, the rotating member 62 is threadedly connected to the moving member 64, and the driving member 63 is used to drive the rotating member 62 to rotate. Since the rotating member 62 and the moving member 64 are threadedly connected, the rotating member 62 can drive the moving member 64 to rotate and move along the first direction when rotating. Since the moving member 64 is fixed on the moving base 20, the rotation of the moving member 64 is restricted. Therefore, the moving member 64 can only move along the first direction, thereby driving the moving base 20 to move along the first direction. The forward drive and reverse drive of the driving member 63 can control the moving direction of the moving base 20. Furthermore, a transmission assembly is provided between the driving member 63 and the rotating member 62, and the transmission assembly includes a transmission member and a gear pair. The axis of the transmission member is set at an angle to the axis of the rotating member 62, and the driving member 63 is connected to the transmission member, and the transmission member and the rotating member 62 are connected via the gear pair. The driving member 63 can drive the transmission member to rotate, and the transmission member can drive the rotating member 62 to rotate via the gear pair. Through the above arrangement, the driving member 63 does not need to be set in the first direction, thereby facilitating the arrangement of the driving member 63. In this embodiment, the axis of the transmission member is perpendicular to the axis of the rotating member 62. In other embodiments, the axis of the transmission member and the axis of the rotating member 62 can also be set at an acute angle or an obtuse angle, and are not limited to this embodiment.

[0039] In this embodiment, the gear pair includes a first bevel gear and a second bevel gear, the first bevel gear being mounted on the transmission member and the second bevel gear being mounted on the rotating member 62, and the first bevel gear and the second bevel gear being meshed. In other embodiments, the transmission assembly may further include a worm structure and a worm wheel, the worm structure being mounted on the transmission member and the worm wheel being mounted on the rotating member 62, and the worm and the worm wheel being meshed, and the present embodiment is not limited thereto.

[0041] Furthermore, a sliding engagement structure 70 is provided between the fixed base 10 and the movable base 20. The sliding engagement structure 70 includes a slide rail 71 and a slider 72. The slide rail 71 extends along a first direction, and the slider 72 slides in engagement with the slide rail 71. The slide rail 71 is provided on one of the fixed base 10 and the movable base 20, while the slider 72 is provided on the other. In this embodiment, the slide rail 71 is provided on the fixed base 10, and the slider 72 is provided on the movable base 20. The provision of the sliding engagement structure 70 makes the movement of the movable base 20 relative to the fixed base 10 more stable and smooth.

[0042] Optionally, there are multiple sliding fit structures 70, and the multiple sliding fit structures 70 are distributed along the first direction and / or the length direction of the vehicle body. That is, the multiple sliding fit structures 70 can be distributed along the first direction, along the length direction of the vehicle body, or along both the first direction and the length direction of the vehicle body.
