[0062] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0063] like Figure 1 to Figure 2As shown, this embodiment provides a front-wheel-drive motor assembly component for installing a front-wheel-drive motor of a vehicle.

[0064] like Figure 1 As shown, the front drive motor assembly provided in this embodiment includes a crossbeam 100, and the crossbeam 100 includes a ventral surface 101 and an airfoil surface 102. It should be understood that the ventral surface 101 is the upper side of the crossbeam 100, the airfoil surface 102 is the side of the crossbeam 100, and the back side is the lower side of the crossbeam 100.

[0065] L-shaped reinforcement 200, the L-shaped reinforcement 200 includes a first reinforcement plate 201 and a second reinforcement plate 202 connected vertically, the first reinforcement plate 201 is fitted and connected to the ventral surface 101, the second reinforcement plate 202 is fitted and connected to the wing surface 102, the ventral surface 101 is provided with a through first positioning hole 103 on one side of the first reinforcement plate 201, and a through second positioning hole 104 on the other side, the first reinforcement plate 201 is provided with a third positioning hole 203 on one side, and a fourth positioning hole 204 on the other side.

[0066] For example, the L-shaped reinforcement 200 is an L-shaped long strip, arranged in the middle area of ​​the cross beam 100, and is welded to the belly surface 101 and the wing surface 102 of the cross beam 100. The setting of the L-shaped reinforcement 200 can solve the problem that the dynamic stiffness of the front drive motor bracket 300 does not meet the standard.

[0067] The first positioning hole 103 and the second positioning hole 104 are both large circular holes, respectively located on both sides of the L-shaped reinforcement 200, the motor bracket 300, and the straight Z-shaped bracket 400, and are used for installation and positioning of the crossbeam 100. The ventral surface 101 and the wing surface 102 are used to maintain a fitting connection state with the L-shaped reinforcement 200 and the straight Z-shaped bracket 400, and provide a support plane for welding the L-shaped reinforcement 200 and the straight Z-shaped bracket 400.

[0068] The motor bracket 300 is arranged on the first reinforcing plate 201 . The motor bracket 300 is provided with a positioning cavity for positioning the front drive motor. A fifth positioning hole 301 is provided on one side of the positioning cavity, and a sixth positioning hole 302 is provided on the other side of the positioning cavity.

[0069] Specifically, the motor bracket 300 is provided with a fifth positioning hole 301 and a sixth positioning hole 302, wherein the fifth positioning hole 301 and the sixth positioning hole 302 are circular holes for suspending and assembling the front drive motor on the motor bracket 300, and can also serve as positioning holes of the motor bracket 300 during welding.

[0070] It should be noted that when the front-drive motor suspension is assembled to the motor bracket 300, the two sides of the front-drive motor should fit with the two sides of the positioning cavity to position the front-drive motor, and the opening size of the motor bracket 300 is required to be larger than the axial width of the front-drive motor suspension. For example, the single-side gap is 0.25mm.

[0071] The straight Z-shaped bracket 400 includes a vertical plate 401, a first horizontal plate 402, and a second horizontal plate 403 arranged in a straight Z shape. The first horizontal plate 402 and the second horizontal plate 403 are respectively connected vertically to the vertical plate. The first horizontal plate 402 is connected to the ventral surface 101 between the first positioning hole 103 and the L-shaped reinforcement 200, and the second horizontal plate 403 is provided with a seventh positioning hole 404. For example, the straight Z-shaped bracket 400 is arranged on one side of the L-shaped reinforcement 200 and welded to the crossbeam 100, which can meet the requirements of motor harness assembly.

[0072] In some embodiments, in combination Figure 1 , 2 As shown, the motor bracket 300 includes a first bracket 303 and a second bracket 304 that are symmetrically arranged. In this embodiment, the motor bracket 300 includes the first bracket 303 and the second bracket 304, which are buckled into a subassembly in the form of left and right lap welding, and then welded to the outer surface of the L-shaped reinforcement 200. The split design of the motor bracket 300 can solve the problem of cracking during the stamping process of the integrated structure.

[0073] In some embodiments, in combination Figure 1 , 2 As shown, the cross beam 100 is an integrally formed long strip cross beam 100. For example, the cross beam 100 is a rectangular profile, which can save mold development investment compared to the conventional upper and lower plate buckle welding form.

[0074] In some embodiments, in combination Figure 1 , 2 As shown, the third positioning hole 203 and the fourth positioning hole 204 are both oblong holes. On the one hand, the oblong holes can be used to provide mounting holes for motor harness assembly, and on the other hand, the oblong holes are used as positioning holes to fix the L-shaped reinforcement 200 on the crossbeam 100 .

[0075] In another embodiment, a tool for a front-drive motor assembly assembly is provided, which is applied to the front-drive motor assembly assembly of any of the above embodiments, including:

[0076] The base 500 provides a supporting work platform for the arrangement and function realization of the tooling of the front-drive motor assembly component, and is provided with a rectangular bottom plate with a certain thickness and a lifting ring 501 for facilitating the movement of the tooling.

[0077] The beam positioning assembly is arranged on the base 500, and the beam positioning assembly includes a first positioning unit 610, a second positioning unit 620, a third positioning unit 630 and a supporting unit 640. The beam positioning assembly is used to stably and reliably fix the above beam 100 at a set ideal position, and provide an accurate reference for the positioning and connection of the L-shaped reinforcement 200, the motor bracket 300 and the straight Z-shaped bracket 400 in the subsequent process.

[0078] The first positioning unit 610 includes a first positioning pin 614 for assembling into the first positioning hole 103 from the back of the beam 100, a first pressing block 611 for pressing the ventral surface 101, and a first driving device 612 for driving the first pressing block 611. It should be understood that the first positioning pin 614 can pass through the first positioning hole 103 to achieve unilateral positioning of the beam 100. The first driving device 612 drives the first pressing block 611 to press the ventral surface 101 of the beam 100, so as to achieve unilateral predetermined pressing of the beam 100 and ensure that the beam 100 does not shift during the welding process.

[0079] The second positioning unit 620 includes a second positioning pin 623 for being assembled into the second positioning hole 104 from the back, a second pressing block 621 for pressing the ventral surface 101, and a second driving device 622 for driving the second pressing block 621. The second positioning pin 623 can pass through the second positioning hole 104 to achieve unilateral positioning of the beam 100. The second driving device 622 drives the second pressing block 621 to achieve unilateral predetermined pressing of the beam 100, ensuring that the beam 100 does not shift during welding.

[0080] The third positioning unit 630 includes a third pressing block 631 for pressing the wing surface 102 and a third driving device 632 for driving the third pressing block 631. The third pressing block 631 realizes lateral positioning of the cross beam 100 in the forward direction of the vehicle, and the third driving device 632 is used to drive the third pressing block 631 to press the side of the cross beam 100 to achieve a predetermined lateral pressing of the cross beam 100, ensuring that the cross beam 100 does not shift laterally during the welding process.

[0081] The support unit 640 includes a support block for fitting with the back support, and the support block can support the back of the beam 100 so that the first pressing block 611, the second pressing block 621, and the third pressing block 631 can press the beam 100 against the support block.

[0082] The motor bracket positioning assembly is arranged on the base 500, and the motor bracket positioning assembly includes a fourth positioning unit 710 and a fifth positioning unit 720. The motor bracket positioning assembly is used to synchronously position the motor bracket 300 and the L-shaped reinforcement 200 on the crossbeam 100, reduce the error accumulation caused by multiple positioning, and improve the installation accuracy level of the motor bracket 300. When the motor bracket 300 is pre-positioned in the motor bracket positioning assembly, the two sides of the positioning cavity are respectively fitted with the motor bracket positioning assembly to ensure that the motor bracket 300 does not move during the welding process.

[0083] The fourth positioning unit 710 includes a fourth driving device 711 , a first limiting block 712 matched with the positioning cavity, a second limiting block 713 connected to the first limiting block 712 , and a third limiting block 714 fixed to the base 500 .

[0084] The fifth positioning unit 720 includes a third positioning pin 721 and a fourth positioning pin 722 respectively connected to the first limit block 712, and a fifth positioning pin 723 cooperating with the fifth positioning hole 301 and the sixth positioning hole 302. The third positioning pin 721 is used to cooperate and connect with the third positioning hole 203, and the fourth positioning pin 722 is used to cooperate and connect with the fourth positioning hole 204.

[0085] The fourth driving device 711 is used to drive the first limit block 712 to cooperate with the insertion of the positioning cavity, and drive the second limit block 713 to press toward the third limit block 714, so that the second limit block 713 and the third limit block 714 clamp the motor bracket 300, and at the same time drive the third positioning pin 721 to be assembled in the third positioning hole 203, and drive the fourth positioning pin 722 to be assembled in the fourth positioning hole 204.

[0086] Among them, the first limit block 712 can not only assist in improving the coaxiality of the installation hole of the motor bracket 300, but also control the opening size of the motor bracket 300 to avoid the problem of too small an opening to fit and too large an opening to cause looseness. When the second limit block 713 and the third limit block 714 cooperate with each other in the working state, the suspended conformal clamping of the motor bracket 300 can be realized to ensure that the position of the motor bracket 300 does not move during welding.

[0087] The fourth driving device 711 provides power to press the L-shaped reinforcement 200 and the motor bracket 300, ensuring that the relative positions of the L-shaped reinforcement 200 relative to the beam 100 and the motor bracket 300 relative to the L-shaped reinforcement 200 do not shift after being pressed.

[0088] The fifth positioning unit 720 is provided with a third positioning pin 721, a fourth positioning pin 722 and a fifth positioning pin 723. Among them, the third positioning pin 721 and the fourth positioning pin 722 can be connected to the first limit block 712 through a conversion block. The third positioning pin 721 and the fourth positioning pin 722 can realize the welding positioning of both sides of the L-shaped reinforcement 200 to ensure that the welding accuracy requirements are met. The fifth positioning pin 723 can realize the installation positioning of the motor bracket 300, which can not only ensure the welding accuracy, but also improve the coaxiality level of the corresponding mounting hole of the motor bracket 300.

[0089] The straight Z-type bracket positioning assembly 810 is arranged on the base 500, and includes a sixth positioning pin 811 cooperating with the seventh positioning hole 404, a fifth clamping block 812 for clamping the second horizontal plate 403, a fifth driving device 813 for driving the fifth clamping block 812, and a fourth limit block 814 for fitting and supporting the back side of the first horizontal plate 402 and the back side of the vertical plate 401.

[0090] The straight Z-type bracket positioning assembly 810 is provided with a sixth positioning pin 811, a fifth pressing block 812, a fifth driving device 813 and a fourth limiting block 814. Among them, the sixth positioning pin 811 can realize the positioning of the upper side of the straight Z-type bracket 400. The sixth driving device can realize the press-fitting of the upper side of the straight Z-type bracket 400. The fourth limiting block 814814 can realize the L-shaped fitting limit of the back of the straight Z-type bracket 400 to ensure that the straight Z-type bracket 400 is welded at a pre-specified position.

[0091] It should be understood that the straight Z-type bracket positioning assembly 810 is used to accurately position the straight Z-type bracket 400 between the crossbeam 100 and the motor bracket 300 to ensure the clearance requirements between the motor harness and the front drive motor and surrounding components to avoid interference problems.

In this embodiment, in order to ensure the accuracy of one-time positioning, shorten the time of placing the beam 100, and improve labor efficiency and welding consistency, a baffle is set on the first positioning unit 610 to play a role of unilateral limiting.

[0094] In some embodiments, the first limit block 712 includes a first movable limit block 7121 and a second movable limit block 7122 with adjustable spacing, and the fourth positioning unit includes an adjustment screw for adjusting the spacing between the first movable limit block 7121 and the second movable limit block 7122. In this embodiment, the adjustment screw can adjust the spacing between the first movable limit block 7121 and the second movable limit block 7122 to control the opening size of the motor bracket 300.

[0095] In some embodiments, the four corners of the base 500 are respectively provided with a plurality of lifting rings 501 for facilitating lifting. The base 500 is provided with a plurality of fixing holes for fixing the base 500.
