[0043] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means three or more, unless otherwise explicitly specified.

[0044] like Figure 1 As shown, an embodiment of this application provides an electric vehicle frame, including a frame body 10, a handlebar bracket 20, a first mounting bracket 30, and a battery compartment bracket 40.

[0045] Among them, the frame body 10, as the main structure of the electric vehicle frame, bears the main structural pressure.

[0046] Optionally, the handlebar bracket 20 is connected to the frame 10, and the handlebar bracket 20 can rotate relative to the frame 10 to achieve steering control of the front wheel.

[0047] Optionally, the first mounting bracket 30 is connected to the handlebar bracket 20. The first mounting bracket 30 is used to mount a control element (ECU), which enables vehicle positioning. Furthermore, placing the control element on the first mounting bracket 30 connected to the handlebar bracket 20 avoids obstruction of the control element, thus ensuring stable wireless signal transmission and allowing personnel to easily and accurately obtain the vehicle's location, reducing operating costs.

[0048] Optionally, the battery compartment bracket 40 is connected to the vehicle frame 10, and the battery compartment bracket 40 can be closed with the vehicle frame 10 to form a battery compartment for placing the battery. When the battery is placed in the battery compartment, the battery compartment can provide a certain degree of protection for the battery, and at the same time, it can limit the position of the battery to ensure that the battery is not affected by the external environment during use and thus does not pose a safety hazard.

[0049] like Figure 2 As shown, in one embodiment, the handlebar bracket 20 includes a grip 21 and a handlebar connector 22. A first end of the handlebar connector 22 is connected to the grip 21, and a second end of the handlebar connector 22 is connected to the frame 10 via a steering element (not shown). It should be noted that the steering element is used to connect to the front wheel assembly (not shown) to control the steering of the front wheel assembly. Furthermore, the handlebar connector 22 is connected to the steering element and also to the grip 21. When steering is required, the user can hold the grip 21 and rotate it to drive the handlebar connector 22 to rotate synchronously. The handlebar connector 22 then drives the steering element to rotate, thus controlling the steering of the front wheel assembly.

[0050] like Figure 3As shown, in one embodiment, the grip 21 includes a first grip portion 211, a second grip portion 212, and a grip connecting portion 213. A first end of the grip connecting portion 213 is connected to the first grip portion 211, and a second end of the grip connecting portion 213 is connected to the second grip portion 212. That is, the first grip portion 211 and the second grip portion 212 are symmetrically arranged at both ends of the grip connecting portion 213 about its center of symmetry. Simultaneously, the grip connecting portion 213 is also connected to the handlebar connector 22. To ensure accurate front wheel steering, the handlebar connector 22 must be positioned at the center of symmetry between the first grip portion 211 and the second grip portion 212, i.e., connected to the center of symmetry of the grip connecting portion 213, thereby ensuring accurate front wheel steering.

[0051] In one embodiment, the first mounting bracket 30 includes a first mounting portion 31 and a second mounting portion 32. The first mounting portion 31 is connected to the second mounting portion 32. Since the grip connection portion 213 has a symmetrical structure, the center of symmetry of the grip connection portion 213 divides the grip 21 into two symmetrical sides. The first mounting portion 31 is connected to one side of the center of symmetry of the grip connection portion 213, and the second connection portion 12 is connected to the other side of the center of symmetry of the grip connection portion 213. A mounting position for setting a control element is formed at the connection between the first mounting portion 31 and the second mounting portion 32. The control element can be installed in the mounting position to achieve installation limitation of the control element.

[0052] like Figure 4 and Figure 5 As shown, in one embodiment, the frame body 10 includes a first connecting portion 11, a second connecting portion 12, and a third connecting portion 13.

[0053] The first connecting part 11 is connected to the handlebar bracket 20. The first connecting part is a tubular structure, which serves as the main beam tube of the frame body 10. Specifically, the part of the first connecting part 11 near the handlebar bracket 20 is provided with a frame head tube 17. The frame head tube 17 is fixedly connected to the main structure of the first connecting part 11 through a head tube fixing bracket 16. The handlebar connector 22 of the handlebar bracket 20 is adapted to extend into the frame head tube 17 and is rotatably connected to the frame head tube 17 and the main structure of the first connecting part 11.

[0054] Furthermore, since the head tube 17 of the frame is mounted on the first connecting part 11 at a certain angle, in this embodiment, the angle can optionally be set to 90° to 120°. A head tube reinforcement 15 is provided at the angle, which strengthens the connection structure between the head tube 17 of the frame and the first connecting part 11.

[0055] Optionally, the first connecting part 11 is also provided with a wire harness clip 18, which can be used to gather the electronic wire harnesses used for connection between various electronic components during the subsequent assembly of the frame.

[0056] Specifically, the second connecting portion 12 is a tubular structure. In this embodiment, there may be two second connecting portions 12, which are symmetrically arranged on both sides of the first connecting portion 11 with the first connecting portion 11 as the center of symmetry. The first ends of both second connecting portions 12 are connected to the first connecting portion 11, and the second ends of the second connecting portions 12 extend horizontally in a direction away from the first connecting portion 11. Furthermore, the second ends of the second connecting portions 12 are bent in a vertical direction. The second connecting portion 12 located at the bottom forms the bottom support structure of the vehicle frame, and the second connecting portion 12 located at the rear forms the rear anti-collision bracket 121 of the vehicle frame.

[0057] Optionally, the second end of the second connecting part 12 is also provided with a battery lock fixing bracket 113. The battery lock fixing bracket 113 can provide an installation platform for the battery lock. When the battery is put into the battery compartment, the installed battery lock cooperates with the lock hole on the battery to achieve mechanical locking of the battery, thereby playing an anti-theft role.

[0058] Optionally, the battery lock mounting bracket 113 is also provided with a rear handrail fixing component 114, which can be used to install the rear handrail to achieve the installation and fixing of the rear handrail.

[0059] Optionally, the second connecting part 12 is also provided with a rear license plate bracket 115, which extends away from the first connecting part 11 and can be used to install the rear license plate.

[0060] Optionally, a bottom armor fixing member 110 is also provided below the second connecting part 12. The bottom armor fixing member 110 is used to install the chassis armor or lower guard plate at the bottom of the frame to protect the lower area of ​​the frame during vehicle operation.

[0061] Optionally, a single support bracket 111 is also provided on the outer side of the second connecting part 12. The single support bracket 111 can be used to install a support component for supporting the vehicle when it is stationary.

[0062] Optionally, the second connecting part 12 is further provided with a second mounting bracket 112, which can be used to install control units such as electronic control components.

[0063] In this embodiment, two third connecting portions 13 may be provided, with each of the two third connecting portions 13 corresponding to one of the two second connecting portions 12. Optionally, the third connecting portions 13 may also be tubular structures. Furthermore, each third connecting portion 13 is formed in a Z-shape, comprising a first part, a second part, and a third part. The first part is connected to one end of the second part, and the other end of the second part is connected to the third part. The second part is bent relative to the first part, and the third part is bent relative to the second part. The first part is adapted to be parallel to the third part. During installation, the first part of the third connecting portion 13 is located at the bottom of the second connecting portion 12 and is parallel to the second connecting portion 12. One end of the second part of the third connecting portion 13 is bent vertically and connected to the first part near the rear end of the frame. The third part of the third connecting portion 13 is connected to the other end of the second part, and simultaneously connected to the vertically bent portion of the second connecting portion 12. Thus, the third connecting portions 13 collectively provide support for the bottom of the formed battery compartment.

[0064] Optionally, a pedal fixing bracket 19 is also provided between the two third connecting portions 13, and the pedal fixing bracket 19 is spaced along the first part of the third connecting portion 13 to form a support structure for mounting the pedal.

[0065] like Figure 4 As shown, in one embodiment, the electric vehicle frame further includes a seat bucket bracket 50, which includes a first seat body 51 and a second seat body 52. ​​The first seat body 51 is a plate-like structure and is disposed between the second connecting portions 12. The second seat body 52 is connected to the first seat body 51 and is arranged in a vertical direction, thereby forming a front support member of the battery compartment.

[0066] Specifically, a seat cushion fixing bracket 53 is also provided on the top of the second seat body 52, which is used for the installation and fixing of the seat cushion.

[0067] like Figure 4 or Figure 5 As shown, in one embodiment, the battery compartment support 40 includes a battery compartment beam 41, a front battery compartment support 42, and a rear battery compartment support 43.

[0068] Among them, the battery compartment surrounding beam 41 is a U-shaped structural component, and the two ends of the U-shaped battery compartment surrounding beam 41 are respectively connected to the vertical second connecting part 12 to form a enclosure and limiting structure on the upper part of the battery compartment.

[0069] The battery compartment front support 42 includes a first base plate 421 and a first side plate 422. The first base plate 421 is connected to the third part of the third connecting part 13, and the first side plate 422 is connected to the second base 52. In this embodiment, the first side plate 422 is connected to the three sides of the first base plate 421, so that a first opening is formed on one side of the formed battery compartment front support 42.

[0070] The battery compartment rear support 43 includes a second base plate 431 and a second side plate 432. The second base plate 431 is disposed between the second connecting portions 12 and connected to the opposite side of the second connecting portions 12. The second side plate 432 is disposed on the side of the second base plate 431. In this embodiment, the second side plate 432 is connected to three sides of the second base plate 431, thereby forming a second opening on one side of the formed battery compartment rear support 43.

[0071] During installation, the battery can be placed vertically in the battery compartment to increase the height of its plug outlet and reduce the risk of water ingress. Furthermore, the first opening of the front battery compartment bracket 42 is aligned with the second opening of the rear battery compartment bracket 43 to ensure that both the front and rear ends of the battery are supported by both brackets after placement. Additionally, the first base plate 421 and the second base plate 431 provide bottom support for the battery inside the compartment, and the first side plate 422 and the second side plate 432 further laterally limit the battery after installation. When the battery contacts the front and rear battery compartment brackets 42 and 43, anti-wear pads can be used to ensure stability after placement and prevent the battery from shifting during driving, thus avoiding noise and collision damage.

[0072] like Figure 2 As shown, in one embodiment, the electric vehicle frame further includes a rear swingarm guard 60. The second connecting portion 12 is provided with a rear swingarm connector 61 on the side opposite to the first connecting portion 11. There may be two rear swingarm connectors 61. The two rear swingarm connectors 61 are respectively connected to the rear swingarm guard 60, and the first ends of each rear swingarm guard 60 converge to form a triangular structure.

[0073] Specifically, the second connecting part 12 has a fixing part 14 on the side opposite to the first connecting part 11. Each fixing part 14 is used to connect to the first end of the shock absorber (not shown in the figure), and the rear swingarm guard 60 is used to connect to the second end of the shock absorber. After the shock absorber is installed, the shock absorber, the rear swingarm guard 60, and the second connecting part 12 together form a triangular structure. The triangular structural design can improve the torsional resistance of the rear of the frame by more than 30%, thereby improving the overall structural strength of the rear swingarm.

[0074] Optionally, the fork guard is also equipped with a rear mudguard bracket 62, which is used to install the rear mudguard. The rear mudguard can prevent the rear wheel from splashing the mud and water it has been running through onto the rider during rotation, thereby protecting the rider.

[0075] Thus, in the above-mentioned electric vehicle frame, by setting a first mounting bracket 30 on the handlebar bracket 20, the first mounting bracket 30 is used to install control elements. By setting the control elements at this location, it is ensured that the signal strength that the control elements can receive is higher, thereby improving the positioning accuracy of the vehicle.

[0076] Furthermore, the battery compartment formed by the cooperation between the battery compartment bracket 40 and the vehicle frame 10 effectively ensures the stability of the battery after it is installed in the vehicle. The design of the battery compartment also ensures effective protection of the battery in harsh environments, preventing potential safety hazards. The battery compartment adopts a dual-fixation structure of "bottom support + side restraint," combined with an anti-wear pad design, ensuring its secure installation and preventing abnormal noises and component collision damage caused by movement during driving. Simultaneously, the vertical placement of the battery increases the height of its connector outlet, reducing the risk of water ingress.

[0077] Furthermore, the overall frame is optimized using CAE tools, effectively controlling the overall weight of the frame to within 10kg and achieving a static load capacity of over 240kg. The rear of the frame uses a combination of a shock absorber, a rear swingarm guard 60, and a second connecting part 12, which together form a triangular structure. This triangular structural design improves the torsional resistance of the rear of the frame by more than 30%, and has passed over 700,000 fatigue vibration tests, making the frame's lifespan far exceed the industry standard for two-wheeled vehicles.

[0078] Furthermore, the joints of the entire frame can be connected by robotic TIG welding. This welding method results in uniform welds and controllable penetration depth. After welding, the frame is subjected to local heat treatment to eliminate welding stress, thereby further improving the overall strength of the frame.

[0079] An embodiment of this application provides a vehicle. This vehicle employs the electric vehicle frame described in any of the above embodiments, and therefore also possesses the aforementioned advantages.
