[0018] The present invention will be further described in detail below with reference to the accompanying drawings.
[0019] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
[0020] Example 1 This embodiment relates to a lifting device for balancing vehicles, referring to... Figures 1-2 The lifting device can be installed under the vehicle through a detachable or fixed assembly method. It includes a frame 100, a sliding component 200, a drive component 300, and a support frame assembly 400, which enables the vehicle to be raised and kept in a balanced state.
[0021] The frame 100 is fixedly installed at the bottom of the vehicle, providing basic support and positioning. One end of the sliding component 200 is fixedly installed on the frame 100, and the other end extends horizontally and connects to the drive component 300, forming an inverted T-shape with the frame 100. It should be noted that the shapes of the sliding component 200 and the frame 100 are not limited. The drive component 300 is installed on the side of the sliding component 200 away from the frame 100, and one end of the sliding component 200 is connected to the output shaft of the drive component 300. In other embodiments, the drive component 300 may also be installed on the frame 100. It should be noted that the drive component 300 can be electrically connected to the in-vehicle control system, meaning the control system can control the output power of the drive component 300, thereby controlling the vehicle's lifting height. One end of the support frame assembly 400 is movably mounted on the sliding component 200, allowing it to slide and rotate relative to the sliding component 200, while its other end is rotatably mounted on the frame 100. The support frame assembly 400 can change its tilt angle under the influence of the sliding component 200. The support frame assembly 400 is equipped with a base 410 parallel to the ground, which is used to contact the ground. When the drive component 300 rotates forward, the drive sliding component 200 increases the tilt angle of the support frame assembly 400, causing the base 410 to contact the ground, thereby lifting the vehicle. When the drive component 300 rotates in reverse, the drive sliding component 200 decreases the tilt angle of the support frame assembly 400, lowering the vehicle height or moving the base 410 away from the ground. This can be adjusted and stored to achieve vehicle level balance. Therefore, the vehicle can be raised, maintaining balance even on uneven ground, providing users with a stable and smooth activity space, improving safety and convenience, enhancing the user experience, and the vehicle balance ensures even force distribution, extending vehicle life. It should be noted that the base 410 can be rotatably mounted or fixedly mounted on the support frame assembly 400, which is not limited here.
[0022] In this embodiment, refer to Figures 3-5The sliding assembly 200 includes a fixed frame 210, a lead screw 220, and a nut 230. One end of the fixed frame 210 has an opening 213 facing the support frame assembly 400 to prevent the support frame assembly 400 from sliding along the lead screw 220. The lead screw 220 is installed inside the fixed frame 210, and one end is connected to the output shaft of the drive member 300. The lead screw 220 rotates under the drive of the drive member 300, converting the rotational power of the drive member 300 into axial power, driving the nut 230 to move axially. The nut 230 is sleeved on the lead screw 220 and threadedly connected to it. It moves axially with the rotation of the lead screw 220, thereby driving the support frame assembly 400 to move axially. Furthermore, one end of the support frame assembly 400 can be rotatably assembled relative to the nut 230, allowing the support frame assembly 400 to move and rotate axially, satisfying the requirements for changing the tilt angle. Specifically, the two ends of the nut 230 are mounted on the inner wall of the fixing bracket 210, reducing sliding friction between the nut 230 and the top of the fixing bracket 210, significantly reducing component wear, and ensuring smooth movement of the nut 230. Specifically, in this embodiment, a protective sleeve is fitted onto the nut 230 to protect it from damage. It should be noted that, referring to... Figures 1-2 The top of the mounting bracket 210 is close to and abuts against the bottom of the vehicle.
[0023] Furthermore, referring to Figure 3 The fixing frame 210 consists of a first groove 211 with one end close to the opening 213 and a second groove 212 with the other end away from the opening 213. The first groove 211 is used for mounting the two ends of the nut 230, achieving stable mounting of the nut 230. Furthermore, the width of the first groove 211 is greater than the width of the second groove 212, allowing the nut 230 to suspend in the air, preventing direct contact between the nut 230 and the top of the fixing frame 210 or any foreign objects falling into the fixing frame 210, thus avoiding significant friction. It should be noted that this lifting device is installed at the bottom of the vehicle. During vehicle operation, due to varying road conditions, campsites, and destinations, mud, sewage, and foreign objects can easily enter the fixing frame 210 of the lifting device. If the nut 230 directly contacts the top of the fixing frame 210, it can easily cause jamming and result in excessive operating current and energy consumption. Specifically, in this embodiment, the cross-section of the fixing frame 210 is convex to prevent the nut 230 from directly contacting the top of the fixing frame 210. In other embodiments, the cross-section of the fixing frame 210 may also have other shapes.
[0024] In this embodiment, the sliding assembly 200 further includes a second roller 240 and a limiting member 250. The second roller 240 is sleeved on both ends of the nut 230 and located within the first groove 211, allowing the second roller 240 to roll axially with the nut 230 within the first groove 211. This converts the sliding friction between the nut 230 and the first groove 211 into rolling friction, further significantly reducing frictional resistance and making the nut 230 move more smoothly, reducing the risk of jamming. The limiting member 250 is installed within the fixing frame 210 on the side away from the drive member 300, used to fix the end of the lead screw 220, limiting excessive displacement of the nut 230 and ensuring the stability of the lead screw 220's rotation.
[0025] In this embodiment, refer to Figure 3 and Figure 5 The support frame assembly 400 includes a main support rod 420 and auxiliary support rods 430. One end of the main support rod 420 is rotatably mounted to a nut 230, and the other end is mounted to a base 410. As the nut 230 moves axially, the main support rod changes its tilt angle, thereby raising and lowering the base 410 to lift the vehicle. Two auxiliary support rods 430 are provided, with one end rotatably mounted to the main support rod 420 and the other end rotatably mounted to the frame 100. Specifically, one end of each auxiliary support rod 430 is symmetrically mounted on both sides of the main support rod 420 via a first fixed shaft (not shown), and the other ends are mounted to the frame 100 via a second fixed shaft (not shown) and a third fixed shaft (not shown), respectively, forming a symmetrical support structure to prevent the main support rod 420 from shifting and to ensure balanced force and stable posture during vehicle lifting. Specifically, in this embodiment, two connecting plates 110 are respectively provided at the left and right ends of the frame 100, and the second fixed shaft and the third fixed shaft are respectively mounted on the two connecting plates 110 for the auxiliary support rod 430 to rotate and assemble. The connecting plates 110 are configured to provide a stable fulcrum for the rotation and assembly of the auxiliary support rod 430. Specifically, in this embodiment, the fixing frame 210 is provided with a clearance hole 214 for accommodating the first fixed shaft.
[0026] Furthermore, referring to Figure 6 Multiple reinforcing ribs 421 are spaced apart inside the main support rod 420, which greatly improves its resistance to bending and deformation without significantly increasing the overall weight of the main support rod 420, preventing the main support rod 420 from bending or breaking when bearing the weight of the vehicle or under lifting force, and ensuring stable load bearing during the lifting process.
[0027] In this embodiment, refer to Figure 3The drive unit 300 includes a drive motor 310, a reduction gearbox 320, and a connecting shaft 330. The drive motor 310 provides the initial rotational power, and its speed and direction can be adjusted through the vehicle's control system. One end of the reduction gearbox 320 is connected to the drive motor 310, and the other end is connected to the lead screw 220, reducing the output speed of the drive motor 310 while increasing the torque to ensure sufficient power to drive the lead screw 220 to rotate. The connecting shaft 330 is located between the reduction gearbox 320 and the lead screw 220, undertaking the power transmission function and making the power transmission smoother.
[0028] Furthermore, the drive component 300 also includes a transmission rod 340. Specifically, the transmission rod 340 is a ball-head shaft. In other embodiments, the transmission rod 340 may also be a cylindrical pin shaft or a spline shaft, or other devices. One end of the transmission rod 340 is fixedly mounted on the side of the drive motor 310 away from the reduction gearbox 320, serving as the force-bearing part for manual operation. When the device is powered off or without power, the user can directly drive the motor 310 shaft to rotate by rotating the transmission rod 340, thereby sequentially driving the reduction gearbox 320, connecting shaft 330, and lead screw 220 to move, thus achieving manual adjustment of the height of the support frame assembly 400. The other end is rotatably mounted on the frame 100, providing support for the transmission rod 340 and ensuring that the force can be efficiently transmitted to the drive motor 310 during manual operation.
[0029] Example 2 Reference Figures 6-8 This embodiment is basically the same as Embodiment 1, except that the sliding assembly 200 further includes a bushing 260 and a first roller 270. The bushing 260 is fitted onto the nut 230, enhancing the overall structural strength of the nut 230, preventing deformation of the nut 230 when bearing the first roller 270 and under stress, and isolating the nut 230 from direct contact with the fixing frame 210. Two first rollers 270 are provided, and are respectively rotatably mounted on the side of the bushing 260 near the top of the fixing frame 210, and slide against the top of the fixing frame 210. The movement of the nut 230 will cause the first rollers 270 to roll, at which point the friction mode becomes rolling friction, thereby reducing the friction force, so that even if foreign objects fall into the fixing frame 210, they can move smoothly. Without the first roller 270, the nut 230 directly contacts the top of the fixing frame 210. When the nut 230 moves axially with the lead screw 220, sliding friction will occur between the two. Furthermore, foreign objects falling into the fixing frame 210 will further increase the friction, easily causing adjustment jamming due to greater frictional resistance, and even wear on the nut 230 and the fixing frame 210. Specifically, in this embodiment, the cross-section of the fixing frame 210 is rectangular. In other embodiments, the cross-section of the fixing frame 210 may also be other shapes.
[0030] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
