[0054] Please refer to Figure 5 and Figure 6 , specifically, the connecting piece 145 can include a connecting frame 1452 and a limiting block 1454, the connecting frame 1452 is fixedly connected to the second connecting part 143, the connecting frame 1452 has a limiting hole 1453 communicating with the adjusting hole 1432, and the limiting block 1454 is fixedly connected to the connecting frame 1452, and the matching part 361 is penetrated through the limiting hole 1453 and the adjusting hole 1432 in sequence and is clamped and cooperated with the limiting block 1454. The connecting piece 145 can limit the position of the matching part 361 through the limiting block 1454, and the connecting stability between the support positioning assembly 30 and the mounting support 14 is improved.

[0055] Please refer to Figure 4 , Figure 6 and Figure 7The connecting frame 1452 is a U-shaped connecting piece, which can include two oppositely spaced side plates and a connecting plate connected between the two side plates. The side plates of the connecting frame 1452 are fixedly connected to the end face of the second connecting part 143, and the limiting hole 1453 is formed on the side plate of the connecting frame 1452 to communicate with the adjusting hole 1432 of the second connecting part 143. The two side plates of the connecting frame 1452 are both provided with the limiting hole 1453, and the positions of the two limiting holes 1453 correspond. The shape of the limiting hole 1453 is matched with the shape of the matching part 361. In order to avoid the rotation of the matching part 361 relative to the connecting frame 1452, the cross-sectional profile of the matching part 361 can not be circular, and the limiting hole 1453 is not a circular hole. As an example, the matching part 361 can be a square rod, and the limiting hole 1453 is a square hole. In this embodiment, the matching part 361 is a cylindrical rod, one side surface of the matching part 361 is a planar limiting surface 3612, and the remaining side surfaces are arc surfaces. The limiting hole 1453 is a circular hole, and the limiting hole 1453 has a planar inner wall matched with the planar limiting surface 3612. When the matching part 361 is inserted into the limiting hole 1453, the planar inner wall of the limiting hole 1453 is opposite to the planar limiting surface 3612, which limits the degree of freedom of the rotation of the matching part 361 relative to the connecting frame 1452, and further improves the connection stability between the two.

[0056] The limiting block 1454 is fixedly connected to the connecting frame 1452, for example, it can be welded to the inner side of the side plate of the connecting frame 1452. The limiting block 1454 is provided with a limiting block slot 1455 at a position corresponding to the limiting hole 1453, and the shape of the limiting block slot 1455 can be substantially the same as that of the limiting hole 1453. The inner wall of the limiting block slot 1455 can further be provided with a first limiting block tooth 1456, and correspondingly, the side wall of the matching part 361 can be provided with a second limiting block tooth 3614. Specifically, the second limiting block tooth 3614 is arranged on the side of the matching part 361 away from the planar limiting surface 3612. In this embodiment, the first limiting block tooth 1456 and the second limiting block tooth 3614 are both V-shaped teeth. The inclined surface of the V-shaped tooth provides guidance when moving relative to each other, allowing the two structures to move smoothly in a specific direction (second direction X). When the tooth top and the tooth groove are aligned, the contact between the two inclined surfaces will prevent further movement, forming a mechanical self-locking effect and achieving lateral limiting. When adjustment is needed, the matching part 361 can be actively forced to move relative to the limiting block 1454 along the second direction X to overcome the friction.

[0057] In order to facilitate the processing of the first limiting block tooth 1456 in the limiting block slot 1455, the limiting block 1454 can be assembled by two structures. As an example, the limiting block 1454 can include a substantially C-shaped main body and a sealing portion, the limiting block slot 1455 is arranged on the C-shaped main body, and the sealing portion can be fixed to the opening of the C-shaped main body by bolts or other fasteners.

The transverse mounting portion 3834 is connected to an end of the vertical connecting portion 3832 away from the sliding block 381 and located on a side of the vertical connecting portion 3832 away from the cooperating portion 361.

[0061] The support 32 is mounted on the transverse mounting portion 3834 for supporting the inner panel 203 of the hood 200. Specifically, the support column 321 is slidably arranged in the transverse mounting portion 3834, and the extending direction of the support column 321 is substantially the same as the extending direction of the vertical connecting portion 3832. The support column 321 is provided with a support end 3212 at one end thereof away from the vertical connecting portion 3832, and the support end 3212 is used for abutting against the inner panel 203. The outer diameter of the support end 3212 can be greater than the outer diameter of other parts of the support column 321 to increase the support area of the inner panel 203. As an example, the support column 321 can be a bolt, and the bolt head with a larger outer diameter is the support end 3212, and the first fixing member 325 can be a nut.

The number of supports 32 can be set to be multiple, and the multiple supports 32 jointly support the inner panel 203, thereby improving the positioning reliability. As an example, the number of supports 32 is set to be two, and correspondingly, the number of first mounting members 38 is also set to be two, and the two first mounting members 38 are arranged on the adjusting portion 363 and spaced apart along the third direction Y.

The connecting block can also include a horizontal mounting portion and a vertical mounting portion. The positioning member 34 is mounted on the horizontal mounting portion. In actual application, the positions of the positioning member 34 and the support member 32 can be adjusted according to the relative positions of the inner plate 203 and the outer plate 201. In the embodiment, in the second mounting member 39, the horizontal mounting portion is connected to one side of the vertical mounting portion close to the fitting portion 361. In the length direction of the adjusting portion 363, the support member 32 and the positioning member 34 are staggered.

[0066] The positioning member 34 is mounted on the horizontal mounting portion of the second mounting member 39, and is used for positioning the outer plate 201 of the engine cover 200. Specifically, the positioning column 341 is arranged in the horizontal mounting portion 3834, and the extension direction of the positioning column 341 is substantially the same as that of the support column 321. The end of the positioning column 341 used for contacting the outer plate 201 is the positioning end 3412. The outer diameter of the positioning end 3412 can be greater than that of other parts of the positioning column 341 to increase the contact area with the outer plate 201.

The outer plate 201 of the engine cover 200 is usually made of conventional steel, and the suction accessory 343 can adsorb the outer plate 201. The column body of the positioning column 341 can be made of steel, and the positioning head of the positioning column 341 is made of a rubber profiled block to fix the outer plate 201 by the magnetic force of the suction accessory 343 without bumping the outer plate 201.

[0068] The second elastic member 345 is sleeved on the positioning column 341 and elastically abuts between the positioning end 3412 and the second mounting member 39. The second elastic member 345 can be a spring, an elastic pad, or the like. The end of the positioning column 341 away from the positioning end 3412 is connected with the second fixing member 347, and the end of the positioning column 341 away from the positioning end 3412 is provided with an external thread. The second fixing member 347 can be a nut, and the second fixing member 347 is used for locking the positioning column 341 to prevent the positioning column 341 from being separated from the second mounting member 39 under the action of the second elastic member 345.

[0069] During positioning, the positioning end 3412 of the positioning column 341 abuts against the outer plate 201, and the suction accessory 343 adsorbs the outer plate 201. The second elastic member 345 allows the positioning column 341 to have an adjusting freedom in the axial direction while being in contact with the outer plate 201, thereby improving the positioning effect of the positioning device 100. The number of positioning members 34 can be set to be multiple, and the multiple positioning members 34 collectively position the outer plate 201, thereby improving the positioning reliability. The support member 32 supports the inner plate 203, and the positioning member 34 adsorbs the outer plate 201, so that the gap between the inner plate 203 and the outer plate 201 at the position coated with damping rubber is kept within a predetermined gap range.

[0070] As an example, the number of positioning members 34 is set to be two, and correspondingly, the number of second mounting members 39 is also set to be two. The two second mounting members 39 are arranged on the adjusting part 363 along the third direction Y, and the two positioning members 34 are arranged between the two support members 32.

The auxiliary support member 35 can also include a support column, a first elastic member and a first fixing member, and the specific positions and connection relationships can be referred to the above description of the support member 32. The auxiliary support member 35 can be located between the two positioning members 34, and is used to assist in supporting the inner plate 201 and improve the positioning effect.

[0073] When the positioning device 100 provided in the application is welded, the engine hood 200 is first assembled to the body-in-white and adjusted, and then the engine hood 200 is lifted up by the support rod. The hole position of the positioning device 100 on the anti-collision beam of the body-in-white is bolted to the anti-collision beam. Then the engine hood 200 is lowered, the front end of the engine hood 200 is locked and supported on the fixed seat 16, and is fixed on the fixed seat 16 through the fastening member. The positions of the first mounting member 38 and the second mounting member 39 are adjusted to make the support member 32 and the positioning member 34 adjust in the third direction Y, the first fixing member 325 and the second fixing member 347 are adjusted to make the support end 3212 and the positioning member 3412 adjust in the height direction, and the matching part 361 and the clamping teeth of the limiting clamping block 1454 are adjusted to make the support member 32 and the positioning member 34 adjust in the second direction X, so that the support positioning assembly 30 is matched with the positions of the inner plate 203 and the outer plate 201 of the engine hood 200. The support member 32 supports the inner plate 203, the positioning member 34 adsorbs the outer plate 201, and the support member 32 and the positioning member 34 jointly fix the engine hood 200, so that the gap between the inner plate 203 and the outer plate 201 at the position coated with damping glue is within the predetermined gap range. Then the body-in-white and the engine hood 200 can be transported, welded, electrophoresed and the like.

[0074] The positioning device 100 provided in the application supports the inner plate 203 through the support member 32 and fixes the outer plate 201 through the positioning member 34, so as to control the gap between the inner plate 203 and the outer plate 203, thereby reducing the possibility of cracking of the damping glue of the engine hood 200 in the welding and transportation processes.
