Description

Technical Field

[0001] This utility model relates to the technical field of electric tricycle carriage frames, specifically a foldable electric tricycle carriage frame. Background Technology

[0002] The electric tricycle's cargo box frame mainly consists of the frame section located above the main frame of the electric tricycle, along with the side and rear cargo box panels connected by hinges. This structure is primarily used for carrying goods on the electric tricycle. However, the cargo box panels of most electric tricycles are quite low, making it difficult to effectively restrain cargo when carrying it. Usually, ropes are needed to secure the goods. Especially when electric tricycles are used for street vending, many owners choose to modify them by raising the cargo box panels or completely altering the original cargo box shape, replacing the original cargo box with an external canopy. Therefore, improvements to the existing tricycle cargo box frames are necessary. Utility Model Content

[0025] This utility model provides a foldable electric tricycle chassis frame. The side panel of the chassis is movably connected to an extension panel via a pin, thereby increasing the height of the original side panel. This facilitates the restriction of goods when carrying them without the need for binding. When used for street vending, the side panel and the extension panel are moved and adjusted on the slide rail via a sliding groove. Then, a fourth hand-tightening screw is threaded into the second fixing hole to limit the movement and adjustment of the side panel. The extension panel and the side panel are then folded. The folded extension panel can be used as a tabletop, increasing the space for placing items when setting up a stall.

[0026] Figures 1-4 The diagram shown is an overall structural schematic of one embodiment of the foldable electric tricycle chassis frame of this utility model. Please refer to [link / reference]. Figures 1-4This embodiment of a foldable electric tricycle chassis includes a first chassis plate 1. A second chassis plate 2 is welded to the right end of the first chassis plate 1.

A side panel 5 of the chassis is slidably connected to the slide rail 4 through a slide groove 12. The slide groove 12 is provided at the lower end of the side panel 5. An extension panel 6 is movably connected to the side panel 5 through a pin. A first fixing lug 7 is fixedly connected to the front side of the extension panel 6 and the right side of the side panel 5, as well as the rear side of the extension panel 6 and the right side of the side panel 5. A first hand-tightening screw 8 is threaded through the first fixing lug 7. The right end of the first hand-tightening screw 8 is threaded into the first fixing hole 3. Second fixing holes 13 are provided on the front and rear sides of the first chassis plate 1 near the left side.

[0027] The front side of the front extension baffle 6 near the bottom and the rear side of the rear extension baffle 6 near the bottom are both fixedly connected to the second fixing ear plate 9. The second fixing ear plate 9 is threaded through with a second hand-tightening screw 10.

[0028] The second hand-tightened screw 10 is threaded through the second fixing ear plate 9 and the third fixing ear plate 11, providing a stable connection between the extension baffle 6 and the side baffle 5 of the carriage. The first hand-tightened screw 8 is threaded through the first fixing ear plate 7 and the first fixing hole 3, further enhancing the stability of the connection between the extension baffle 6 and the side baffle 5 of the carriage. The second hand-tightened screw 10 and the first hand-tightened screw 8 are high-strength screws, or the relevant fixing structures of the second hand-tightened screw 10 and the first hand-tightened screw 8 can be replaced with existing latches, that is, the original position of the third fixing ear plate 11 is replaced with a latch. The original second fixing ear plate 9 is replaced with a latch, which is used to connect and fix the extension baffle 6 and the side baffle 5 of the carriage through the latch. The original first fixing ear plate 7 is replaced with a latch. Hooks are fixedly installed on the front and rear sides of the second frame plate 2. Depending on the situation, the width of the second frame plate 2 is reduced accordingly, so that the front and rear ends of the second frame plate 2 and the front and rear sides of the extension baffle 6 are flush, which facilitates the locking of the latch and further enhances the connection stability between the extension baffle 6 and the side baffle 5 of the carriage. The carriage frame also includes a rear baffle section of the carriage, and the location of the rear baffle is shown in the attached figure of this patent specification. Figure 1 At the opening in the middle, this part can refer to the existing technology, and is movably connected between the rear panel hinge and the first frame plate 1, and then locked and fixed by the latch and buckle, which is highly adaptable.

[0029] The side panel 5 of the carriage includes a first auxiliary support leg 501. The front side of the front carriage side panel 5 and the rear side of the rear carriage side panel 5 near the left side are rotatably connected to the first auxiliary support leg 501 through a first disc damping shaft.

A support frame 504 is fixedly connected to the right end of the adjusting screw 503.

[0030] Turn the third hand screw 502 away from the third fixing hole 506, rotate and unfold the first auxiliary support leg 501, and then turn the adjusting screw 503 through the abutment 504 to make it contact the ground, further supporting the side panel 5 of the carriage. When not in use, rotate and store the first auxiliary support leg 501, and turn the third hand screw 502 threadedly into the third fixing hole 506 to limit and fix it.

[0031] The side panel 5 of the carriage also includes a connecting plate 505. The front side of the front side panel 5 and the rear side of the rear side panel 5 are both fixedly connected to the connecting plate 505. The connecting plate 505 is located on the right side of the rotating connection of the first auxiliary support leg 501. A third fixing hole 506 is provided on the connecting plate 505. A support plate 507 is fixedly connected to the inner side of the carriage side panel 5. A connecting bracket 508 is fixedly connected to the outer side of the connecting plate 505 near the right side. A fourth hand-tightening screw 509 is threaded through the side of the connecting bracket 508.

[0032] After the side panel 5 of the carriage and the extension panel 6 are moved and adjusted on the slide rail 4 via the slide groove 12, the fourth hand-tightening screw 509 is threaded into the second fixing hole 13 to limit the movement and adjustment of the side panel 5 of the carriage.

[0033] The extension baffle 6 includes a receiving groove 601 formed on the inner end of the extension baffle 6, and the inner wall of the receiving groove 601 is rotatably connected to a second auxiliary support leg 603 via a second disc damping shaft 602.

[0034] The second auxiliary support leg 603 is rotated and unfolded to contact the first frame plate 1, further supporting the extension baffle 6.

[0035] Combination Figures 1-4The specific usage process of the foldable electric tricycle frame of this embodiment is as follows: When using it for street vending, turn the first hand screw 8 to disengage it from the first fixing hole 3, and move and adjust the side panel 5 of the vehicle body together with the extension panel 6 on the slide rail 4 through the slide groove 12. Then, thread the fourth hand screw 509 into the second fixing hole 13 to limit the movement and adjustment of the side panel 5 of the vehicle body. Turn the second hand screw 10 to disengage it from the third fixing ear plate 11 and fold the extension panel 6. Under the action of the support plate 507, the folded and adjusted extension panel 6 will have a certain support effect. Rotate and unfold the second auxiliary support leg 603 to contact the first frame plate 1, which will further support the extension panel 6. Turn the third hand screw 502 away from the third fixing hole 506 and rotate and unfold the first auxiliary support leg 501. Then, turn the adjusting screw 503 through the abutment 504 to make it contact the ground, which will further support the side panel 5 of the vehicle body.
