Description

Technical Field

[0001] This utility model relates to the field of electric vehicle frame technology, specifically to a front frame for an electric vehicle. Background Technology

[0002] Electric vehicles, used for short-distance travel, typically have a basket installed at the front of the frame to carry personal belongings. However, the structural support method of the front basket has long had significant problems. Existing electric vehicles generally use a suspended support structure for the front basket, where the load and vibration of the basket can only be transmitted through the main support rod, the front stem, or local weak weld points. The force path is curved and discontinuous, resulting in insufficient bending rigidity in the basket area. To address this, we propose a new front frame for electric vehicles. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a front frame for electric vehicles to solve the problems existing in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An electric vehicle front frame includes a battery frame, a basket frame, reinforcing columns, and main support rods. The lower end of the reinforcing column is fixedly connected to the battery frame, and the upper end of the reinforcing column is fixedly connected to the basket frame, so that the load of the basket frame can be transferred to the battery frame along the reinforcing column. A connecting plate is fixedly connected between the front ends of the main support rods. The connecting plate is only connected to the main support rods and is used to enhance the lateral stability of the front frame.

[0006] Preferably, the basket frame is located at the front of the vehicle and extends forward to support the basket.

[0007] Preferably, it also includes a front riser, the lower end of which is fixedly connected to the battery rack, and the upper end of which is used to connect to the head tube.

[0008] Preferably, the reinforcing column and the front riser form a longitudinal stress-bearing structure at the front end of the vehicle.

[0009] Preferably, the main support rods are set as two symmetrical rods, which are used to provide structural support for the basket frame in the left and right directions.

[0010] Preferably, the basket frame is equipped with a baffle that is connected to the side wall of the basket.

[0011] Preferably, the headlights are installed below the basket frame.

[0012] This utility model provides a front frame for an electric vehicle. It has the following advantages:

[0013] 1. By setting up reinforcing columns, an independent longitudinal load-bearing structure is formed between the basket frame and the battery rack, allowing the load of the basket to be directly transferred to the lower battery rack, thereby significantly improving the stability of the load.

[0014] 2. The front ends of the left and right main support rods are connected by connecting plates to form a lateral rigid structure. At the same time, the connecting plates are only connected to the main support rods and do not participate in the connection of other components, so that the lateral reinforcement effect is more concentrated, thereby enhancing the overall torsional resistance of the front frame in the left and right directions, improving the stability of the vehicle when turning or being subjected to lateral impact, and also improving the lateral stability of the basket frame.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, what is described is only a part of this utility model, not all of it. Based on this utility model, all other inventions obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] See attached document Figure 1 An electric vehicle front frame includes: a battery rack 1, a front riser 11, a head tube 12, a main support rod 2, a basket rack 21, a baffle 22, a basket 23, a reinforcing column 24, a connecting plate 25, and a front light 3.

[0019] The battery rack 1 is located at the lower front part of the vehicle frame and is used to support and position the battery. It is the main load-bearing foundation of the lower front frame. To improve the vertical and longitudinal rigidity of the battery rack 1 in the front end area, the front end of the battery rack 1 is fixedly connected to the lower end of the reinforcing column 24.

[0020] The reinforcing column 24 is a columnar structure, preferably made of metal tubing such as carbon steel or aluminum alloy, and its axial direction is basically along the front-rear direction of the vehicle. The lower end of the reinforcing column 24 is welded to the front end of the battery rack 1, and the upper end is fixedly connected to the rear or bottom of the basket frame 21, so that the reinforcing column 24 forms a vertical load-bearing member between the battery rack 1 and the basket frame 21. Through the setting of the reinforcing column 24, the load of the basket, the vibration of the basket frame, and the front impact force can be effectively transferred to the battery rack 1, improving the overall bending and vibration resistance of the front frame.

[0021] The front riser tube 11 is arranged obliquely upwards and forwards, with its lower end fixedly connected to the upper side of the battery rack 1, and its upper end welded to the head tube 12. The head tube 12 is used to mount the steering column and serves as the steering bearing seat for the front fork assembly and handlebar assembly. The front riser tube 11 and the reinforcing column 24 together constitute the main load-bearing system at the front end, transmitting the impact force during vehicle operation from the front end area to the battery rack 1.

[0022] The main support rods 2 are configured as two symmetrical rods, with their rear ends connected to the main frame body and their front ends extending forward towards the vehicle. The front end of each main support rod 2 is fixedly connected to the connecting plate 25 and the basket frame 21, respectively. The main support rods 2 provide lateral support to the basket area and are the main side beam structure of the front frame.

[0023] The connecting plate 25 has a U-shaped structure, with its left and right ends fixedly welded to the front ends of the two main support rods 2, so that the connecting plate 25 spans between the left and right main support rods 2, thereby enhancing the lateral stability of the front frame. It should be noted that the connecting plate 25, as a lateral reinforcement, is only connected to the main support rods 2 and is not connected to the basket frame 21, the reinforcing column 24, or other components.

[0024] The basket frame 21 is located above the connecting plate 25, but the two are not directly connected. The left and right ends of the basket frame 21 are fixedly connected to the left and right main support rods 2, respectively, and extend forward of the vehicle under the support of the main support rods 2, forming the mounting position of the basket 23 at the front end. The bottom of the basket frame 21 is fixedly connected to the upper end of the reinforcing column 24, so that the basket frame 21 obtains stable support from the reinforcing column 24 in the longitudinal direction.

[0025] The basket 23 is installed at the front end of the basket frame 21 and can be fixed by screws or buckles. It is used to carry items in the vehicle. To improve the stability of the basket 23, a baffle 22 is provided on one side of the basket frame 21. The baffle 22 is fixedly connected to the side wall of the basket 23 to provide lateral limiting for the basket 23 and prevent the basket from shaking during driving.

[0026] The front headlight 3 is installed at the bottom of the basket frame 21. The bottom mounting method can avoid the basket blocking the light and facilitate the wiring harness to be laid along the bottom of the frame, improving the convenience and neatness of wiring.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
