Description

Technical Field

[0001] This utility model relates to the field of electric tricycle technology, specifically to an integrated high-strength frame for electric tricycles. Background Technology

[0002] The frame of an electric tricycle serves as the skeleton of the entire vehicle, and the quality of its structure directly determines the structural strength of the whole vehicle. An integrated frame refers to a frame structure that connects key components such as main beams, side beams, and cross beams into one piece through integral molding or continuous welding processes, replacing the traditional segmented welding design and achieving structural integration.

[0003] Currently, the front and rear bodies of electric tricycles have different functions, resulting in the front body frame being smaller than the rear body frame due to extrusion molding or continuous welding. This can lead to insufficient energy absorption area in the event of a collision, making it difficult to effectively protect the driver and increasing the risk of injury.

[0004] Therefore, we propose an integrated high-strength frame for electric tricycles. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated high-strength frame for electric tricycles to solve the problem mentioned in the background art that when a vehicle is involved in a collision during driving, the front and rear frame may have insufficient energy absorption areas, which may not effectively protect the driver and increase the risk of injury in the accident.

[0008] Preferably, the positioning plate passes through the interior of the L-shaped central beam and is tightly pressed against the L-shaped central beam; the positioning plate is bent and then pressed to connect to the inner side of the L-shaped central beam.

[0009] Preferably, both ends of the reinforcing rib are provided with connecting blocks that have grooves, and the grooves of the connecting blocks are tightly pressed into the interior of the L-shaped beam.

[0010] Preferably, both ends of the side beam are fixedly connected to one end of an L-shaped side beam, and the L-shaped side beam is fixedly connected to multiple rear longitudinal beams.

[0011] Preferably, the inner side of the L-shaped beam is provided with two centrally symmetrical V-shaped reinforcing beams, and the two V-shaped reinforcing beams can form an X-shaped support surface.

[0012] Preferably, one end of the L-shaped center beam is fixedly connected to the front tube, and the front tube is located on the outside of the side beam.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] Please see Figures 1-4 The electric tricycle shown in the diagram has an integrated high-strength frame, including an L-shaped side beam 1 for shaping, a front longitudinal beam 2 fixedly connected to the inner side of the L-shaped side beam 1, an L-shaped center beam 3 fixedly connected to the front of the vehicle body, a reinforcing rib 4 above the L-shaped center beam 3, a side beam 5 fixedly connected to one end of the L-shaped center beam 3, a rear longitudinal beam 6 fixedly connected to the other end of the L-shaped center beam 3, a V-shaped reinforcing beam 7 below the L-shaped center beam 3, and a connecting beam 8 on one side of the rear longitudinal beam 6. This invention uses the L-shaped center beam to connect the reinforcing rib and two V-shaped reinforcing beams fixedly connected to the L-shaped center beam. The two V-shaped reinforcing beams are respectively fixedly connected to the junction of the L-shaped side beam and the front longitudinal beam and the junction of the L-shaped side beam and the rear longitudinal beam, thereby enhancing the compressive strength and energy absorption strength of the front of the vehicle body, thus reducing the problem of personnel injury due to insufficient strength in vehicle collisions.

[0026] Furthermore, the V-shaped reinforcing beam 7 is connected to a positioning plate 701. One end of the V-shaped reinforcing beam 7 is fixedly connected to the junction of the L-shaped side beam 1 and the front longitudinal beam 2, and the other end of the V-shaped reinforcing beam 7 is fixedly connected to the junction of the L-shaped side beam 1 and the rear longitudinal beam 6. The positioning plate 701 passes through the interior of the L-shaped middle beam 3 and is tightly pressed against the L-shaped middle beam 3. After bending, the positioning plate 701 is pressed against the inner side of the L-shaped middle beam 3. The inner side of the L-shaped middle beam 3 is provided with two centrally symmetrical V-shaped reinforcing beams 7. The two V-shaped reinforcing beams 7 can form an X-shaped support surface. The positioning plate is connected through the middle of the V-shaped reinforcing beam, so that it can be quickly positioned during installation and is easy to assemble.

[0027] Furthermore, both ends of the reinforcing rib 4 are provided with connecting blocks 401 that have grooves. The grooves of the connecting blocks 401 are tightly pressed into the interior of the L-shaped central beam 3. The L-shaped central beam has positioning holes, which allow the reinforcing rib to be quickly positioned. At the same time, the reinforcing rib is squeezed at the positioning holes to ensure the stability of the connection between the reinforcing rib and the L-shaped central beam and the support strength of the L-shaped central beam.

[0028] Furthermore, both ends of the side beam 5 are fixedly connected to one end of the L-shaped side beam 1, the L-shaped side beam 1 is fixedly connected to multiple rear longitudinal beams 6, and one end of the L-shaped middle beam 3 is fixedly connected to the front tube 301. The front tube 301 is located on the outside of the side beam 5. The side beam is fixedly connected to both the L-shaped side beam and the L-shaped middle beam to ensure the connection strength of the vehicle body.

[0029] In this scheme, the assembly process is as follows: The L-shaped side beam 1 is positioned on a tooling fixture, ensuring that both side beams are parallel. The front longitudinal beam 2 is vertically welded to the inner side of the L-shaped side beam 1 using carbon dioxide gas shielded welding, resulting in a continuous weld without breaks. The connecting blocks 401 at both ends of the reinforcing rib 4 are embedded into the internal groove of the L-shaped middle beam 3, and pressure is applied using a hydraulic press to ensure no gaps. The L-shaped middle beam 3 is then welded and fixed to the front longitudinal beam 2. Next, the positioning plate 701 of the V-shaped reinforcing beam 7 is passed through the pre-reserved channel inside the L-shaped middle beam 3, bent, and pressed tightly against the inner side of the L-shaped middle beam 3. Then, one end of the V-shaped reinforcing beam 7 is welded to the junction of the L-shaped side beam 1 and the front longitudinal beam 2, and the other end is welded to the junction of the L-shaped side beam 1 and the rear longitudinal beam 6, forming a triangular support structure. Two V-shaped reinforcing beams 7 are symmetrically installed, forming an X-shaped support surface after welding, improving the torsional strength of the frame. The rear longitudinal beam 6 is vertically welded to the rear end of the L-shaped side beam 1 and connected to the connecting beam 8 via fillet welds.
