Description

Technical Field

[0001] This utility model relates to the field of self-balancing vehicle frame technology, and in particular to a self-balancing electric vehicle frame. Background Technology

[0002] A self-balancing electric vehicle is a personal transportation tool based on dynamic balancing technology. Its core principle is to achieve automatic vehicle balance through sensors, control algorithms, and a motor drive system.

[0003] Existing self-balancing electric vehicle frames have certain limitations in terms of dynamic response speed, especially when driving at high speeds or encountering complex road conditions. The frame's balance adjustment capability is weak, which can easily lead to vehicle imbalance and affect driving stability and safety.

[0004] Secondly, some self-balancing electric vehicle frames employ complex multi-link or other mechanical structures. While these improve the frame's balance to some extent, they also increase manufacturing and maintenance costs. The complex mechanical structures not only increase assembly difficulty during production but also place higher cost pressures on subsequent maintenance and repairs. Therefore, we propose a self-balancing electric vehicle frame. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Current self-balancing electric vehicle frames have limitations in dynamic response speed, especially at high speeds or on complex road conditions, where their balance adjustment capability is weak, easily leading to vehicle imbalance and affecting driving stability and safety. Secondly, some self-balancing electric vehicle frames employ complex multi-link or other mechanical structures, which, while improving balance performance to some extent, also increase manufacturing and maintenance costs. These complex mechanical structures not only increase assembly difficulty during production but also place higher cost pressures on subsequent maintenance and repairs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A self-balancing electric vehicle frame includes a frame body and a center of gravity adjustment device. The center of gravity adjustment device is installed below the frame body. The frame body has locking grooves on both sides of its bottom end. The center of gravity adjustment device is locked into the locking grooves. Several counterweights are slidably connected inside the center of gravity adjustment device.

[0008] Furthermore, the main body of the frame is divided into a front rod, a central frame, and a rear frame. The central frame is threadedly connected to the rear frame, and a central column is threadedly connected to the top of the front rod.

[0009] Furthermore, connecting plates are symmetrically welded to the middle of both sides of the central frame, and a protrusion is provided on one end of the top layer of the central frame that connects to the front rod. A first groove is provided on the protrusion, and a second groove is provided on both sides of the front rod. A snap-fit ​​block is provided in the second groove, and the snap-fit ​​block fits into the first groove.

[0010] Furthermore, a third groove is symmetrically provided on the outer walls of both sides of the center of gravity adjustment device. A rotating shaft is installed in the third groove, and a fixing plate is installed on the rotating shaft. The fixing plate is installed in a snap-fit ​​groove opened at the bottom of the frame body, and the rotation angle of the fixing plate is 5°-10°.

[0011] Furthermore, several linear motors are equidistantly arranged on one side of the center of gravity adjustment device, and the output end of the linear motor extends into the center of gravity adjustment device and is connected to a counterweight.

[0012] Furthermore, a slide rail is installed at the bottom of the center of gravity adjustment device, and several slide tracks are opened on the slide rail, with the counterweight block slidably connected to the slide tracks.

[0013] Furthermore, the movement trajectories of the several counterweights are consistent, the moving distance of the counterweights is equal to the length of the slide rail, and the counterweights are electrically connected to the on-board sensors inside the electric vehicle.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model achieves rapid adjustment of the center of gravity by installing a center of gravity adjustment device under the main body of the vehicle frame and using a linear motor to drive the counterweight block to slide on the slide rail. The movement of the counterweight block is controlled in real time by on-board sensors, which can quickly adjust the position of the center of gravity according to the vehicle body tilt angle, speed and road conditions, significantly improving the dynamic response speed of the vehicle frame.

Detailed Implementation

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the embodiments of this utility model.

[0024] Example 1

[0025] like Figure 1-4 As shown, this utility model provides a technical solution: a self-balancing electric vehicle frame, including a frame body 1 and a center of gravity adjustment device 2. The center of gravity adjustment device 2 is installed below the frame body 1. The frame body 1 has snap-fit ​​grooves on both sides of its bottom end. The center of gravity adjustment device 2 is snapped into the snap-fit ​​grooves. Several counterweights 201 are slidably connected inside the center of gravity adjustment device 2. The center of gravity adjustment device 2 is integrated below the frame body 1. The counterweights 201 are driven by a linear motor 205. The layout is compact and makes full use of the internal space of the frame.

[0026] Example 2

[0027] like Figure 1-4As shown, the main body 1 of the frame is divided into a front rod 101, a central frame 102, and a rear frame 103. The central frame 102 and the rear frame 103 are threaded together. The top of the front rod 101 is threaded with a central column 104. Connecting plates 105 are symmetrically welded to the middle of both sides of the central frame 102. A protrusion 106 is provided on the top layer of the central frame 102 that connects to the front rod 101. A first groove 107 is provided on the protrusion 106. A second groove 108 is provided on both sides of the front rod 101. A snap-fit ​​block 109 is provided in the second groove 108. The snap-fit ​​block 109 fits into the first groove 107. The frame adopts a modular design and is divided into three main modules: front, middle, and rear. They are connected by high-strength quick-release connectors, which simplifies the maintenance and upgrade process and reduces maintenance costs.

[0028] The center of gravity adjustment device 2 has symmetrically provided third grooves 202 on both outer walls. A rotating shaft 203 is installed in the third groove 202. A fixing plate 204 is installed on the rotating shaft 203. The fixing plate 204 is installed in the snap-fit ​​groove at the bottom of the frame body 1. The rotation angle of the fixing plate 204 is 5°-10°. Several linear motors 205 are equidistantly arranged on one side of the center of gravity adjustment device 2. The output end of the linear motor 205 extends into the center of gravity adjustment device 2 and is connected to a counterweight 201. A slide rail 206 is installed at the bottom of the center of gravity adjustment device 2. Several slide tracks are provided on the slide rail 206, and the counterweight 201 is slidably connected to the slide tracks. The movement trajectory of the several counterweights 201 is consistent. The movement distance of the counterweight 201 is equal to the length of the slide rail 206. The counterweight 201 is electrically connected to the vehicle-mounted sensor in the electric vehicle. The position of the counterweight 201 is monitored in real time by the vehicle-mounted sensor and automatically adjusted according to the vehicle tilt angle, speed and road conditions.

[0029] The frame body 1 is made of honeycomb composite material with internal reinforcing ribs. The use of honeycomb composite material with internal reinforcing ribs significantly improves the rigidity and impact resistance of the frame. The honeycomb structure has excellent lightweight and energy absorption characteristics, which not only reduces the weight of the frame but also enhances its resistance to deformation. At the same time, the reinforcing ribs further enhance the overall strength of the frame, ensuring safety and stability under complex road conditions.

[0030] The working process of this utility model is as follows: When using a self-balancing electric vehicle frame, firstly, when the vehicle tilts during driving (such as when turning or bumping), the on-board sensor detects the tilt angle and direction. Based on the tilt data, the control system quickly calculates the number and position of the counterweights 201 that need to be moved. Then, the linear motor 205 drives the counterweights 201 to slide along the slide rail 206 to adjust the center of gravity of the frame and restore the balance of the vehicle. The fixed plate 204 makes a fine adjustment of the angle (5°-10°) around the pivot 203 to further optimize the center of gravity adjustment effect.
