Description

Technical Field

[0001] The utility model relates to the technical field of two-wheeled vehicles, in particular to a frame of a two-wheeled vehicle for non-road use. Background Art

[0002] When parking, existing household two-wheeled vehicles (such as battery vehicles) need to rely on a stabilizing frame installed at the bottom of the vehicle body to keep the two-wheeled vehicle in a stable state. The upper end of the existing two-wheeled vehicle stabilizing frame is rotatably connected to the bottom of the vehicle body. When the two-wheeled vehicle is in a parked state, the stabilizing frame is rotated downward to make it contact with the ground, and the two-wheeled vehicle is supported by the stabilizing frame to keep it stable; when the two-wheeled vehicle is in a driving state, the stabilizing frame is rotated upward and retracted.

[0003] However, in order not to affect the normal driving of the two-wheeled vehicle, the top width of the existing two-wheeled vehicle stabilizer frame is smaller than the width of the vehicle body, resulting in a smaller lateral contact width with the ground when the stabilizer frame is in a supporting state, poor lateral stability of the two-wheeled vehicle, and weak anti-rollover ability, which makes the two-wheeled vehicle prone to rollover when subjected to lateral force. Summary of the invention

[0004] The utility model aims to solve the deficiencies in the prior art and provide a two-wheeled vehicle frame for off-road use.

[0005] The purpose of the utility model is achieved through the following technical solutions: a non-road two-wheeled vehicle frame, comprising a frame body and a stabilizing frame, a fixed shaft is provided at the lower end of the frame body, the stabilizing frame comprises an upper rod body and a lower rod body, the upper rod body is rotatably connected to the fixed shaft, intermediate rod bodies are respectively connected to the two sides of the upper rod body, a first piston is provided at one end of the intermediate rod body away from the upper rod body, sleeves are respectively provided on both sides of the lower rod body, the first piston is connected to the sleeve; a first cavity is formed between the first piston and the bottom of the sleeve, a first return spring is provided in the first cavity; a liquid medium is filled in the first cavity; guide holes are respectively provided on both sides of the lower rod body, a movable anti-roll bar is slidably connected in the guide hole, and a telescopic actuator is provided between the movable anti-roll bar and the bottom of the guide hole; the telescopic actuator is connected to the first cavity through a liquid guide tube; when the fluid medium in the first cavity flows into the telescopic actuator through the liquid guide tube, the telescopic actuator drives the movable anti-roll bar to extend outward.

[0006] In the utility model, when the two-wheeled vehicle is parked, the stabilizer frame is rotated downward, and the lower rod body at the lower end of the stabilizer frame contacts the ground. At this time, the weight of the two-wheeled vehicle is applied to the stabilizer frame, and the intermediate rod body moves downward under the pressure of the gravity of the two-wheeled vehicle, and drives the first piston to move downward, so that the liquid medium in the first cavity is pressed into the telescopic actuator through the liquid guide tube, so that the telescopic actuator drives the active anti-roll bar to extend outward. After the active anti-roll bar is extended, the bottom width of the stabilizer frame is increased, thereby effectively improving the stability of the two-wheeled vehicle when parked and enhancing the anti-rollover ability of the two-wheeled vehicle. When the stabilizer frame is folded, the gravity pressure of the two-wheeled vehicle on the intermediate rod body disappears, and the first piston is reset under the action of the first reset spring, and the liquid medium flows back into the first cavity, so that the active anti-roll bar is retracted to the initial state, thereby preventing the active anti-roll bar from extending outward and affecting the normal driving of the two-wheeled vehicle.

[0007] Preferably, the telescopic actuator includes a cylinder body, in which a second piston is arranged, a second cavity is formed between the second piston and one end of the cylinder body, and a liquid guide tube connects the first cavity with the second cavity; a second return spring is arranged between the second piston and the other end of the cylinder body; a piston rod is arranged on the second piston, and the piston rod is connected to one end of the movable anti-roll bar.

[0010] Preferably, a reinforcing rod body is provided between the intermediate rod bodies.

[0011] Preferably, a cushion block is provided on the lower side of the lower rod body.

[0012] Preferably, the cushion block is made of rubber.

[0013] The beneficial effect of the utility model is as follows: in the utility model, when the two-wheeled vehicle is parked, the stabilizing frame is rotated downward, and the lower rod body at the lower end of the stabilizing frame contacts the ground. At this time, the weight of the two-wheeled vehicle will be used on the stabilizing frame, and the middle rod body moves downward under the pressure of the gravity of the two-wheeled vehicle, and drives the first piston to move downward, thereby pressing the liquid medium in the first cavity into the telescopic actuator through the liquid guide tube, so that the telescopic actuator drives the active anti-roll bar to extend outward. After the active anti-roll bar is extended, the bottom width of the stabilizing frame is increased, thereby effectively improving the stability of the two-wheeled vehicle when parked and enhancing the anti-rollover ability of the two-wheeled vehicle.

DETAILED DESCRIPTION

[0018] 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 belong to the scope of protection of the utility model.

[0019] like Figures 1 to 3 As shown, a non-road two-wheeled vehicle frame includes a frame body 1 and a stabilizer frame 4. The lower end of the frame body 1 is provided with a fixed shaft 2. The stabilizer frame 4 includes an upper rod body 41 and a lower rod body 42. The upper rod body 41 is rotatably connected to the fixed shaft 2. The upper rod body 41 is a tubular structure, and the upper rod body 41 is sleeved on the fixed shaft 2 and can rotate around the fixed shaft 2. The upper rod body 41 is connected to the middle rod body 43 on both sides, and the middle rod body 43 is arranged vertically with the upper rod body 41. The middle rod body 43 is provided with a first piston 45 at one end away from the upper rod body 41, and sleeves 46 are provided on both sides of the lower rod body 42. The first piston 45 is connected to the sleeve 46; a first cavity 47 is formed between the first piston 45 and the bottom of the sleeve 46, and a first return spring 48 is provided in the first cavity 47; and a liquid medium is filled in the first cavity 47. In this embodiment, the liquid medium is hydraulic oil.

[0020] Guide holes 411 are respectively provided on both sides of the lower rod body 42, and a movable anti-roll bar 49 is slidably connected in the guide hole 411. A telescopic actuator is provided between the movable anti-roll bar 49 and the bottom of the guide hole 411. The telescopic actuator is connected to the first cavity 47 through a liquid guide tube 413. When the fluid medium in the first cavity 47 flows into the telescopic actuator through the liquid guide tube 413, the telescopic actuator drives the movable anti-roll bar 49 to extend outward.

[0021] In the utility model, when the two-wheeled vehicle is parked, the stabilizer frame 4 is rotated downward, and the lower rod body at the lower end of the stabilizer frame 4 contacts the ground. At this time, the weight of the two-wheeled vehicle is applied to the stabilizer frame 4, and the intermediate rod body 43 is pressed downward by the gravity of the two-wheeled vehicle, and drives the first piston 45 to move downward, so that the liquid medium in the first cavity 47 is pressed into the telescopic actuator through the liquid guide tube 413, so that the telescopic actuator drives the active anti-roll bar 49 to extend outward. After the active anti-roll bar 49 extends out, the bottom width of the stabilizer frame 4 is increased, thereby effectively improving the stability of the two-wheeled vehicle when parked and enhancing the anti-rollover ability of the two-wheeled vehicle. When the stabilizer frame 4 is folded, the gravity pressure of the two-wheeled vehicle on the intermediate rod body 43 disappears, and the first piston 45 is reset under the action of the first reset spring 48, and the liquid medium flows back into the first cavity 47, so that the active anti-roll bar 49 is retracted to the initial state, so as to prevent the active anti-roll bar 49 from extending outward and affecting the normal driving of the two-wheeled vehicle.

[0022] Among them, a reinforcing rod body 44 is provided between the middle rod bodies 43, and the reinforcing rod body 44 is perpendicular to the middle rod body 43. The reinforcing rod body 44 is used to enhance the structural strength and stability of the entire stabilizing frame 4. A tension spring 3 is provided between one side of the stabilizing frame 4 and the frame body 1. The tension spring 3 provided between the frame body 1 and the stabilizing frame 4 can apply tension to one side of the stabilizing frame 4, which can assist in the folding of the stabilizing frame 4. A cushion block 412 is provided on the lower side of the lower rod body. Preferably, the cushion block 412 is made of rubber.

[0023] Specifically, the telescopic actuator includes a cylinder body 423, which is fixed at the bottom of the guide hole 411. A second piston 419 is arranged in the cylinder body 423, and a second cavity 420 is formed between the second piston 419 and one end of the cylinder body 423. The liquid guide tube 413 connects the first cavity 47 with the second cavity 420; a second return spring 422 is arranged between the second piston 419 and the other end of the cylinder body 423, and a piston rod 421 is arranged on the second piston 419, and the piston rod 421 is connected to one end of the movable anti-roll bar 49. The arrangement direction of the piston rod 421 is parallel to the length direction of the guide hole 411. When the liquid medium in the first cavity 47 flows into the second cavity 420 through the liquid guide tube 413, the second piston 419 is pushed to move by the liquid medium, thereby driving the piston rod 421 to move, so that the piston rod 421 pushes the movable anti-roll bar 49 to extend outward; when the stabilizer frame 4 is folded, the second piston 419 is reset under the action of the second reset spring 422, the movable anti-roll bar 49 is pulled into the guide hole 411, and the liquid medium in the second cavity 420 flows back to the first cavity 47.

[0024] Furthermore, a restraining groove 416 is provided on the intermediate rod body 43, and the restraining groove 416 is arranged along the axial direction of the intermediate rod body 43; a fixing plate 414 is provided on the sleeve 46, and a convex shaft 415 is provided on the fixing plate 414, and the convex shaft 415 extends into the restraining groove 416. The convex shaft 415 can only move within the length range of the restraining groove 416, and the relative movement distance between the intermediate rod body 43 and the sleeve 46 is limited by the cooperation between the convex shaft 415 and the restraining groove 416, so as to prevent the intermediate rod body 43 and the sleeve 46 from being separated.

[0025] The lower rod body is provided with a limiting groove 410, which is arranged along the axial direction of the lower rod body, and the movable anti-roll bar 49 is provided with a limiting protrusion 418, which is connected to the limiting groove 410. The limiting protrusion 418 can only move within the length range of the limiting groove 410, thereby limiting the moving stroke of the movable anti-roll bar 49 and preventing the movable anti-roll bar 49 from being separated from the guide hole 411.

[0026] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
