Description

Technical Field

[0001] This utility model relates to the technical field of frame crossbeams for electric vehicles, and more particularly to a frame crossbeam for an electric vehicle. Background Technology

[0002] The frame crossbeam (commonly known as the "main beam" or "crossbeam") is the core load-bearing structure of the electric vehicle (battery vehicle) frame. It is usually a horizontally arranged metal tube / beam that connects the left and right sides of the frame and mainly undertakes the functions of supporting the vehicle body, fixing the battery, and resisting impact.

[0003] For example, Chinese Patent Publication No. CN215399131U discloses a new type of steel tube crossbeam for electric vehicles. In this comparative patent, the front and rear middle frames are reinforced and connected by auxiliary reinforcing bars. The reinforcement method is simple, resulting in poor reinforcement effect. Moreover, the position of the reinforcement structure (auxiliary reinforcing bars) is fixed, which makes the distance between the front and rear middle frames fixed. Therefore, the crossbeam cannot be used to adjust the overall width of the frame (i.e., the distance between the front and rear middle frames). This makes it inconvenient to adapt to different sizes of batteries and racks according to actual conditions, reducing the adaptability of the frame. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a frame crossbeam for electric vehicles, so as to solve the problem that the existing frame crossbeams are single and fixed, and cannot change the width of the overall frame, resulting in poor frame adaptability.

[0005] Based on the above objectives, this utility model provides a frame crossbeam for an electric vehicle, which is applied to the frame. The frame includes a main beam tube, a front fork tube, a side bar one, and a side bar two. The frame crossbeam includes a reinforcing bar one and a reinforcing bar two.

[0006] The first reinforcing rod is connected to the main beam tube. Both the first and second reinforcing rods have placement cavities at their ends. Both the first and second side rods have sliding rods that are inserted into the placement cavities. A crossbeam assembly is provided between the first and second reinforcing rods. Rotating the crossbeam assembly can drive the first and second side rods to move closer or further apart from each other, thereby changing the overall width of the frame.

[0007] Preferably, the crossbeam assembly includes a crossbeam rod, which is fixedly connected between reinforcing rod one and reinforcing rod two. The crossbeam rod has a slot, and a push-pull part is rotatably connected inside the slot.

[0008] Preferably, the first reinforcing rod, the crossbeam rod, and the second reinforcing rod are integrally formed.

[0009] Preferably, the push-pull part includes a bidirectional threaded rod rotatably connected in the slot, and two threaded sleeves are threadedly connected to the bidirectional threaded rod. A connecting rod is hinged to one side of each of the two threaded sleeves, and the end of the connecting rod away from the threaded sleeve is hinged to the side rod.

[0010] Preferably, a connecting rod 2 is hinged to the other side of each of the two threaded sleeves, and the end of the connecting rod 2 away from the threaded sleeve is hinged to the side rod 2.

[0011] Preferably, the end of the bidirectional threaded rod away from the main beam tube passes through the second reinforcing rod and is fixed with a rotating column.

[0012] The beneficial effects of this utility model are as follows: The electric vehicle frame crossbeam provided by this utility model, through the setting of the crossbeam assembly, and the rotation column can be driven to rotate by an external electric screwdriver, thereby changing the distance between side rod one and side rod two under the pushing and pulling of connecting rod one and connecting rod two, thereby achieving the purpose of adjusting the overall width of the frame, which is convenient to adapt to different battery sizes, racks or user body shapes according to actual conditions, and improves the overall adaptability of the frame.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0019] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, a frame crossbeam of an electric vehicle is applied to the frame. The frame includes a main beam tube 1, a front fork tube 2, a first side bar 3 and a second side bar 4. The front fork tube 2 is fixed to the main beam tube 1. The frame crossbeam includes a first reinforcing bar 5 and a second reinforcing bar 6.

[0021] Reinforcing rod 15 is connected to the main beam tube 1. Both reinforcing rod 15 and reinforcing rod 26 have placement cavities at their ends. Side rod 13 and side rod 24 are fixed with sliding rods 7 inserted into the placement cavities. A crossbeam assembly is provided between reinforcing rod 15 and reinforcing rod 26. Rotating the crossbeam assembly can drive side rod 13 and side rod 24 to move closer or further apart to change the overall width of the frame.

[0022] Both side rod 3 and side rod 4 have two sliding rods 7, allowing them to slide to reinforce rod 5 and reinforce rod 6 via the sliding rods 7. When it is necessary to adjust the distance between side rod 3 and side rod 4, the crossbeam assembly can be rotated to simultaneously drive side rod 3 and side rod 4 to move closer or further apart from each other. After adjustment, the crossbeam assembly can be locked in time, thus achieving the purpose of adjusting the width of the frame.

[0023] In a preferred embodiment of this utility model, the crossbeam assembly includes a crossbeam rod 8, which is fixedly connected between a first reinforcing rod 5 and a second reinforcing rod 6. The first reinforcing rod 5, the crossbeam rod 8, and the second reinforcing rod 6 are integrally formed, which increases the stability of the related structure. The crossbeam rod 8 has a slot, and a push-pull part is rotatably connected in the slot.

[0024] The push-pull part includes a bidirectional threaded rod 9 rotatably connected in the slot. Two threaded sleeves 10 are threadedly connected to the bidirectional threaded rod 9. The bidirectional threaded rod 9 has two external threads with opposite directions, and the two threaded sleeves 10 are located on the two external threads respectively. A connecting rod 11 is hinged to one side of each of the two threaded sleeves 10. The end of the connecting rod 11 away from the threaded sleeve 10 is hinged to the side rod 3.

[0025] The other side of each of the two threaded sleeves 10 is hinged with a connecting rod 12, and the end of the connecting rod 12 away from the threaded sleeve 10 is hinged to the side rod 4.

[0026] The end of the bidirectional threaded rod 9 away from the main beam tube 1 passes through the reinforcing rod 2 6 and is fixed with a rotating column 13. The rotating column 13 is a hexagonal prism and can be driven by an external electric screwdriver, avoiding manual rotation.

[0027] When it is necessary to adjust the width of the frame (i.e., change the distance between side rod 3 and side rod 4), the rotating column 13 is driven to rotate by an external electric screwdriver, which in turn drives the bidirectional threaded rod 9 to rotate. Since the two threaded sleeves 10 are threadedly connected to the bidirectional threaded rod 9, and the sliding rod 7 restricts the rotation of side rod 3 and side rod 4, the two threaded sleeves 10 can move closer or further apart on the bidirectional threaded rod 9. When the two threaded sleeves 10 move closer to each other on the bidirectional threaded rod 9, under the transmission action of the two connecting rods 11, side rod 3 and side rod 4 will be pulled closer to each other, thereby achieving the purpose of adjusting the width of the frame. The connecting rods 11, 12, and the bidirectional threaded rod 9 also play a supporting and reinforcing role for side rod 3 and side rod 4.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
