Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle frames, in particular to a high-performance lightweight electric motorcycle frame. Background Art

[0002] The frame is similar to the skeleton of the human body. It is the mounting base for the various assemblies of the electric motorcycle and connects the motor with the body and other assemblies into an organic whole. In addition to bearing the mass and effective load of the various assemblies of the electric motorcycle, the frame of the electric motorcycle also bears various forces and moments as well as various static and dynamic loads generated during the driving of the electric motorcycle. Therefore, the quality of the electric motorcycle frame becomes particularly important.

[0003] However, when an existing electric motorcycle frame is in use, a position for placing a battery box is usually separately provided in the middle of the frame, and the battery packs in the battery box are usually tightly together. As the batteries age, gaps are more likely to appear between the battery packs and the frame, making it easier for the battery box to rub against the frame, resulting in a greater probability of damage to the battery pack due to friction. In addition, due to the large size of the battery box, a larger hole needs to be reserved in the middle of the frame for placing the battery box, so that the number of structures in the middle of the frame that can play a connecting and supporting role needs to be reduced, resulting in a small number of connecting structures between the electric motorcycle frames, making the overall load capacity of the frame poor. Utility Model Content

[0004] The purpose of the utility model is to provide a high-performance lightweight electric motorcycle frame to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-performance lightweight electric motorcycle frame, comprising a frame body, a battery box is fixedly connected to the bottom of the front end of the frame body, a first partition is fixedly connected to the inner wall of the battery box, a cross bar is fixedly connected to the top of the first partition, second partitions are fixedly connected to the two side walls of the first partition, movable plates are provided on both sides of the second partition, a spring is provided on one side of the movable plate, an inclined plate is fixedly connected to the junction of the front and rear ends of the frame body, a straight strip plate is embedded in the top of the inclined plate, a storage box is fixedly connected to one end of the inclined plate, a third bottom support is provided at the bottom of the storage box, and a first bottom support and a second bottom support are respectively provided at the bottom of the battery box.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figures 1 to 4 As shown, the high-performance lightweight electric motorcycle frame of this embodiment includes a frame body 1, a battery box 7 is fixedly connected to the bottom of the front end of the frame body 1, a first partition 3 is fixedly connected to the inner wall of the battery box 7, a cross bar 2 is fixedly connected to the top of the first partition 3, and the second partition 4 is fixedly connected to the two side walls of the first partition 3. A movable plate 6 is provided on both sides of the second partition 4, and a spring 13 is provided on one side of the movable plate 6. A diagonal plate 9 is fixedly connected to the intersection of the front and rear ends of the frame body 1, a straight strip plate 10 is embedded in the top of the diagonal plate 9, and a storage box 12 is fixedly connected to one end of the diagonal plate 9. A third bottom support 11 is provided at the bottom of the storage box 12, and a first bottom support 5 and a second bottom support 8 are provided at the bottom of the battery box 7, respectively.

[0024] Specifically, the material of the frame body 1 is mainly made of seamed steel pipes, hot-rolled plates and carbon fiber materials, with an overall light weight and high strength. The battery box 7 and the frame body 1 are an integrated structure, and the material is the same as that of the frame body 1, so that the battery box 7 is not easily damaged after being impacted, and the battery pack in the battery box 7 can be effectively protected. The first partition 3 can separate the battery packs to a suitable distance to avoid close contact between the battery packs, thereby reducing the probability that all battery packs in the battery box 7 cannot be used after one of the battery packs in the battery box 7 leaks, and reducing mutual interference between battery packs. The cross bar 2 can strengthen the support for the first partition 3 and the top of the battery box 7, so that the strength of the battery box 7 is improved, and the movable plate 6 can be used to separate the battery packs on the side wall of the second partition 4. The battery pack is clamped between the partitions to reduce the probability of loosening due to aging and shrinkage, thereby reducing the probability of friction damage between the aging battery pack and the frame and the battery box 7. The spring 13 can clamp the battery pack through the force generated by its own deformation. The inclined plate 9 can provide additional support for the turning point where the frame body 1 is connected to enhance the load strength at the connection between the frame body 1. The straight strip 10 is made of carbon fiber material, which can enhance the overall strength of the inclined plate 9. In addition to increasing the static load of the frame, the storage box 12 can also increase the support and limit of the frame as a whole. The third bottom support 11 can support the bottom end of the storage box 12, and the first bottom support 5 and the second bottom support 8 can support the bottom end of the battery box 7, thereby enhancing the impact resistance of the battery box 7.

[0025] Furthermore, the first bottom support 5 and the second bottom support 8 are both fixedly connected to the frame body 1, and the first bottom support 5 and the second bottom support 8 are respectively located on both sides of the bottom end of the battery box 7, and the tops of the first bottom support 5 and the second bottom support 8 are in contact with the battery box 7, thereby reinforcing the battery box 7 and at the same time providing a laterally reinforced connection structure in the middle portion of the frame body 1.

[0026] Furthermore, a first connecting rod 15 is fixedly connected to one side wall of the first bottom support 5 and the second bottom support 8. The first connecting rod 15 is located at the bottom of the battery box 7. The first connecting rod 15 connects the first bottom support 5 and the second bottom support 8 to each other, so that the first bottom support 5 and the second bottom support 8 can better support the battery box 7.

[0027] Furthermore, a second connecting rod 16 is fixedly connected to one side wall of the second bottom support 8 and the third bottom support 11. The second connecting rod 16 is located at the bottom of the inclined plate 9. The second connecting rod 16 can enhance the support for the inclined plate 9 so that the load on the inclined plate 9 can be stronger.

[0028] Furthermore, one end of the spring 13 is fixedly connected to the movable plate 6, and the other end of the spring 13 is fixedly connected to the second partition 4. The spring 13 is deformed after being squeezed by the battery pack on the movable plate 6, and can generate a reverse force, so that the movable plate 6 clamps the battery pack in the space enclosed by the first partition 3, the second partition 4 and the battery box 7.

[0029] Furthermore, both side walls in the middle of the second partition 4 are movably penetrated by a clamping rod 14, one end of which is fixedly connected to the movable plate 6, and the spring 13 is movably sleeved and connected to the clamping rod 14. The clamping rod 14 can increase the stability of the movable plate 6 during movement, so that the force directions of the movable plate 6 and the spring 13 remain on the same horizontal line.

[0030] Furthermore, the movable plate 6 is movably connected to the second partition 4 through the clamping rod 14 and the spring 13. After being pushed by the spring 13, the movable plate 6 can limit the battery placed between the partitions, thereby achieving the clamping and fixing of the battery pack by the movable plate 6.

[0031] The method of using this embodiment is as follows: when using the present high-performance lightweight electric motorcycle frame, the battery packs can be placed in the battery box 7 space divided by the first partition 3 and the second partition 4 respectively. At this time, the movable plate 6 on the second partition 4 will be subjected to the force of the placed battery pack to squeeze the spring 13, causing the spring 13 to deform and produce a reaction force, pushing the movable plate 6 to squeeze the battery pack, so that the battery pack is clamped and fixed in the area divided by the partition and the battery box 7, so that each battery pack is separated by a corresponding distance, so that each battery pack is only connected in series through a wire without any contact, which is conducive to the battery pack maintaining its own stability. At the same time, the first bottom support 5, the second bottom support 8 and the first connecting rod 15 can support the battery box 7 and the battery pack in the battery box 7. When various components are installed in the frame body 1, the third bottom support 11, the second connecting rod 16 and the inclined plate 9 can support the static load of the frame body 1.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
