Description

Technical Field

[0001] The utility model relates to the technical field of electric bicycles, in particular to a steering limiting structure for electric bicycles. Background Art

[0002] An electric bicycle is a mechatronic personal transportation vehicle that uses a battery as an auxiliary energy source and is based on an ordinary bicycle and is equipped with a motor, controller, battery, handlebars, brake handles and other operating components and a display instrument system.

[0003] When an electric bicycle is driving, it will turn when it encounters a fork in the road. When turning, the driver applies pressure to the handrail with both hands, and the handrail drives the turning rod and the front fork to rotate, so that the front fork drives the front wheel to deflect to a certain angle, and the front wheel can travel along the specified path. However, the current electric bicycles do not limit the deflection angle of the turning rod. This leads to the driver's careless driving or slippery ground in rainy days, causing the wheel to drive the front fork and the turning rod to deflect acutely, and the deflection angle of the turning rod cannot be controlled, so that the deflection of the handlebar will hit the driver, causing the body of the electric bicycle to tip over, and the driver's driving safety cannot be guaranteed. Utility Model Content

[0004] The utility model aims to solve the problem that the turning rod on the electric bicycle in the prior art cannot be limited, and proposes a steering limiting structure for the electric bicycle.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, the sleeve is an annular structure, and four positioning rods extending into the clamping plate are fixedly mounted on the sleeve, and fixing bolts corresponding to the clamping plate are threadedly connected on the positioning rods.

[0008] Preferably, the bracket is an annular structure, and a limiting frame extending outside the pipe sleeve is fixedly mounted on the bracket, the limiting frame is a T-shaped structure, and a locking bolt corresponding to the pipe sleeve is threadedly connected to the limiting frame.

[0009] Preferably, evenly distributed reinforcement frames are welded between the bracket and the deflection plate, and two limit plates are vertically arranged at both sides of the deflection plate.

[0010] Preferably, a moving rod is provided on the sliding sleeve of the limit plate, and a pressure plate that resists the deflection plate is fixedly mounted on the moving rod, a support plate is fixedly mounted on the moving rod, and a spring that matches the moving rod is welded between the support plate and the limit plate.

[0011] Preferably, the moving rod is arranged horizontally, the limiting plate and the pressure plate are both provided with a rubber layer, and the spring is welded horizontally.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The utility model installs a matching clamping plate and sleeve on the rotating rod, and installs a limit plate on the pipe sleeve, so that the limit plate can intercept the deflected deflection plate, so that the turning angle of the electric bicycle during driving is limited, thereby protecting the driver.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4, a steering limit structure for an electric bicycle, comprising a sleeve 1 on the electric bicycle, wherein a bearing 3 is arranged in the sleeve 1, a rotating rod 2 for steering the electric bicycle is installed in the sleeve 1 through the bearing 3, and a front fork 4 is arranged on the rotating rod 2, and the electric bicycle can be driven after being powered on. This technical solution is a prior art and will not be elaborated on in detail here;

[0022] A card plate 5 is fixedly mounted on the rotating rod 2, and a sleeve 6 corresponding to the card plate 5 is slidably sleeved on the rotating rod 2. The sleeve 6 is an annular structure. Four positioning rods 7 extending into the card plate 5 are fixedly mounted on the sleeve 6, and fixing bolts corresponding to the card plate 5 are threadedly connected to the positioning rods 7. The card plate 5 and the sleeve 6 are connected by extending the positioning rods 7 on the sleeve 6 into the card plate 5 and using the fixing bolts.

[0023] A deflection plate 8 is installed on the sleeve 6, a bracket 9 is installed in the pipe sleeve 1, and two limit plates 11 corresponding to the deflection plate 8 are fixedly installed on the bracket 9. The bracket 9 is an annular structure, and a limit frame 10 extending outside the pipe sleeve 1 is fixedly installed on the bracket 9. The limit frame 10 is a T-shaped structure, and a locking bolt corresponding to the pipe sleeve 1 is threadedly connected on the limit frame 10. The bracket 9 is installed in the pipe sleeve 1 so that the bracket 9 can surround the sleeve 6, and the limit frame 10 is connected to the pipe sleeve 1 through the locking bolt. It should be noted that when assembling the bracket 9, the installation angle of the two limit plates 11 needs to be checked so that the deflection plate 8 can be located in the middle of the two limit plates 11;

[0024] The two limit plates 11 can intercept the deflected deflection plate 8, so that the deflection angle of the deflection plate 8 is limited, thereby preventing the rapid rotation of the rotating rod 2 from causing instability of the electric bicycle body, and effectively improving the driving safety of the driver;

[0025] A uniformly distributed reinforcement frame 12 is welded between the bracket 9 and the deflection plate 8, and two limit plates 11 are vertically arranged at both sides of the deflection plate 8. A moving rod 13 is slidably sleeved on the limit plate 11, and a pressure plate 14 that is movably opposed to the deflection plate 8 is fixedly installed on the moving rod 13;

[0026] A support plate 15 is fixedly mounted on the moving rod 13, and a spring 16 matching the moving rod 13 is welded between the support plate 15 and the limiting plate 11. The moving rod 13 is horizontally arranged, and both the limiting plate 11 and the pressure plate 14 are provided with a rubber layer. The spring 16 is horizontally welded. By arranging a reinforcement frame 12 and a movable pressure plate 14 on the limiting plate 11, the deflection plate 8 will not directly impact the limiting plate 11 during deflection, and the limiting plate 11 can be protected by the buffering of the rubber layer, thereby improving the service life of the limiting plate 11.

[0027] The functional principle of the utility model can be explained through the following operation modes:

[0028] The electric bicycle often turns during driving, and the turning pressure is transmitted to the rotating rod 2 through the handrail, and the rotating rod 2 drives the front fork 4 to turn the electric bicycle;

[0029] When the rotating rod 2 rotates, the sleeve 6 is driven to rotate through the clamping plate 5, so that the sleeve 6 drives the deflection plate 8 to rotate, and the deflection plate 8 is deflected 90° to the left or right;

[0030] When the deflection plate 8 is deflected, it will firstly move against the pressure plate 14, so that the pressure plate 14 drives the moving rod 13 to slide in the limit plate 11. When the moving rod 13 drives the clamping plate 5 to extend backward, the spring 16 is stressed, so that the pressure plate 14 is in full contact with the rubber layer of the limit plate 11, and the deflected deflection plate 8 is intercepted by the pressure plate 14 and the limit plate 11;

[0031] When the deflection plate 8 returns to the initial position under the traction of the rotating rod 2 , the pressure plate 14 returns to the initial position under the action of the spring 16 .

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
