[0034] The present application is further described in detail below with reference to the accompanying drawings.

[0035] The present application discloses an electric vehicle frame conveying device, referring to Figure 1 and Figure 2 The conveying device includes a conveyor belt 1. In this embodiment, the conveyor belt 1 is a chain plate conveyor belt. Positioning posts 2 are welded to the conveyor plate surface of the conveyor belt 1. Two positioning posts 2 are spaced apart along the length of a chain plate. A fixing block 21 is welded to the top of the positioning post 2. The fixing block 21 is truncated cone-shaped, and the peripheral wall of the fixing block 21 is tilted away from the conveyor plate surface of the conveyor belt 1. A first bottom plate 3 is detachably connected to the conveyor belt 1. The first bottom plate 3 has a rectangular plate surface and a locking assembly 5 is provided on the bottom plate surface. A limit assembly 4 is provided on the first bottom plate 3. An unlocking assembly 6 is installed at one end of the conveyor belt 1 in the longitudinal direction.

[0036] Reference Figure 1 The limiting assembly 4 includes a card plate 41 for limiting the main bracket of the electric vehicle frame. The board surface of the card plate 41 is U-shaped, and the U-shaped opening direction of the card plate 41 is opposite to the rotation direction of the conveyor belt 1. The card plate 41 is fixed to the first base plate 3 by bolts. There are two card plates 41 and they are spaced apart along the length direction of the board surface of the first base plate 3. The positions of the two card plates 41 match the two legs of the main bracket of the electric vehicle frame. The bottom of the card plate 41 is processed to form a card groove 42.

[0037] When using this conveying device, the first base plate 3 is placed on the conveyor belt 1, and the locking assembly 5 at the bottom of the first base plate 3 is connected to the conveyor belt 1. The electric vehicle frame is placed on the conveyor belt 1 so that the main bracket of the electric vehicle frame is embedded in the card slot 42 and clamped and fixed. The electric vehicle frame moves on the conveyor belt 1, and the staff on both sides of the conveyor belt 1 assemble the electric vehicle frame. When the electric vehicle frame moves to near the end of the conveyor belt 1, the unlocking assembly 6 will release the fixing of the locking assembly 5, making it convenient for the staff to remove the first base plate 3 from the conveyor belt 1 and embed the main bracket of the electric vehicle frame into the card slot 42, which can increase the stability of the electric vehicle frame fixed on the conveyor belt 1. The first base plate 3 is connected to the conveyor belt 1 by the locking assembly 5, which can increase the stability of the electric vehicle frame fixation, ensuring that the electric vehicle frame can be firmly fixed on the conveyor belt 1 when the staff performs assembly.

[0038] Reference Figure 2 The locking assembly 5 includes a locking rod 51, and a locking groove 52 is provided at the bottom of the first base plate 3. There are two locking grooves 52 spaced apart along the length direction of the first base plate 3. The positions of the two locking grooves 52 correspond to the positions of the two positioning columns 2 respectively, and the fixing block 21 can be clamped in the locking groove 52. The side wall of the locking groove 52 is provided with a sliding groove 53. There are two sliding grooves 53 and they are symmetrically opened. The locking rod 51 is slidably set in the sliding groove 53. One end of the locking rod 51 extends into the locking groove 52 and is processed to form an inclined surface inclined to the conveyor belt 1. A first elastic member 54 is welded to one end of the locking rod 51 located in the sliding groove 53. In this embodiment, the first elastic member 54 is a spring. One end of the first elastic member 54 is connected to the locking rod 51, and the other end is welded to the bottom of the sliding groove 53.

[0039] When using this conveying device, the first base plate 3 is placed on the conveyor belt 1, and the inclined surface of the locking rod 51 is in contact with and slides against the inclined edge of the fixing block 21, and the locking rod 51 is retracted into the locking groove 52 and compresses the first elastic member 54. When the locking rod 51 moves to below the fixing block 21, the elastic force of the first elastic member 54 pushes the locking rod 51 out of the locking groove 52, so that a section of the locking rod 51 extending out of the locking groove 52 is located below the locking rod 51, so as to limit the first base plate 3, ensure that the first base plate 3 will not detach from the conveyor belt 1, and ensure that the electric vehicle frame can be firmly fixed on the conveyor belt 1 when the staff performs assembly work.

[0040] Reference Figure 1 and Figure 2The unlocking assembly 6 includes a T-shaped rod 61, which is slidably arranged at a section of the positioning column 2 away from the fixed block 21. The end face length of the large head end of the T-shaped rod 61 is the same as the end face diameter length of the bottom of the fixed block 21, and can abut against the inclined surfaces of the two locking rods 51 and push the locking rods 51. The bottom of the T-shaped rod 61 is processed to form a slope, and the end of the conveyor belt 1 is fixed with an unlocking plate 62 by bolts. The top surface of the unlocking plate 62 is a slope. When the T-shaped rod 61 moves with the conveyor belt 1 until it is in contact with the plate surface of the unlocking plate 62, the T-shaped rod 61 moves along the lock column toward the fixed block 21.

[0041] When using this conveying device, the electric vehicle frame moves with the conveyor belt 1 to the end of the conveyor belt 1, and the inclined surface at the bottom of the T-bar 61 fits and slides with the surface of the unlocking plate 62. As the conveyor belt 1 moves, the T-bar 61 moves along the positioning column 2 toward the fixed block 21 and pushes the inclined surface of the locking rod 51, so that the locking rod 51 shrinks into the locking groove 52. When the staff removes the first base plate 3 from the conveyor belt 1, the inclined surface of the locking rod 51 will slide along the inclined edge of the fixed block 21 and extend out of the locking groove 52, making it convenient for the staff to place and fix the first base plate 3 on the conveyor belt 1 again, and unlock the locking assembly 5 by pushing the T-bar 61 through the unlocking plate 62, making it convenient for the staff to remove the first base plate 3 at the end of the conveyor belt 1.

[0042] Reference Figure 1 and Figure 2 The conveying device also includes a second base plate 7, a locking assembly 5 is provided at the bottom of the second base plate 7, a front fixing card 8 for fixing the front wheel of the electric vehicle is rotatably provided on the second base plate 7, and the front fixing card 8 includes a rotating seat 81, which is rotatably provided on the second base plate 7, and a first clamping block 82 is rotatably provided on the rotating seat 81. The first clamping blocks 82 are symmetrically provided in two pieces and the plate surfaces are opposite to each other. The opposite sides of the tops of the two first clamping blocks 82 are processed to form inclined surfaces.

[0043] When using this conveying device, the second base plate 7 is placed on the conveyor belt 1 and fixed by the locking assembly 5, so that the front wheel of the electric vehicle frame can be embedded and fixed between the two first clamping blocks 82. The inclined surface of the first clamping block 82 makes it convenient for the staff to embed the front wheel of the electric vehicle into the front fixing card 8. The rotating seat 81 can make the front wheel of the electric vehicle turn without falling off from the front fixing card 8, which is convenient for rotating the front wheel of the electric vehicle during assembly work and ensures that the electric vehicle frame will not fall off from the conveyor belt 1 when the staff is assembling.

[0044] Reference Figure 1 and Figure 2The conveying device also includes a third base plate 9, a locking assembly 5 is provided at the bottom of the third base plate 9, and a rear fixing card 10 for fixing the rear wheel of the electric vehicle is fixed to the third base plate 9 by bolts. The rear fixing card 10 includes a second clamping block 101, and two second clamping blocks 101 are arranged at intervals along the length direction of the third base plate. The top opposite sides of the two second clamping blocks 101 are processed to form an inclined surface.

[0045] When using this conveying device, the third base plate is placed on the conveyor belt 1 and fixed by the locking assembly 5, so that the rear wheel of the electric vehicle can be embedded and fixed between the two second clamping blocks 101. The inclined surface of the second clamping block 101 makes it convenient for the staff to embed the rear wheel of the electric vehicle into the rear fixing card 10. The rear fixing card 10 can ensure that the electric vehicle frame will not move on the conveyor belt 1 during assembly by the staff.

[0046] Reference Figure 1 The two first clamping blocks 82 and the two second clamping blocks 101 have anti-slip pads 11 bonded to their opposite sides.

[0047] When using this conveying device, the anti-slip pad 11 can ensure that the front and rear wheels of the electric vehicle are firmly clamped in the front fixing card 8 and the rear fixing card 10, and increase the stability of the electric vehicle frame fixed on the conveyor belt 1 by increasing the friction force, ensuring that the electric vehicle frame will not fall over when the staff is assembling it.
