Description

Technical Field

[0001] The present invention relates to the technical field of parking locks for electric vehicles, and in particular to a wedge-shaped parking lock for electric vehicles. Background Art

[0002] Although living standards have improved and nearly every household now owns a car, the demand for electric vehicles seems undiminished. Electric vehicles are not only a means of transportation; they've also gained widespread popularity thanks to their compact size, suitability for short distances, and ease of handling traffic jams. However, residential communities and parking lots lack sufficient anti-theft measures for non-motorized vehicles. In reality, motorcycles and electric scooters are the most vulnerable vehicles. Because they are lighter than cars, have simpler protective measures, and are easily resold, they frequently become targets for thieves. Because the value of stolen property is low and the target is relatively small, even reporting it to the police can be difficult to recover. Consequently, many car owners often simply accept their bad luck when their beloved vehicles are stolen, with some even resorting to refinishing their newly purchased vehicles. Reducing the theft rate of both vehicles in cities, combating and deterring the rampant behavior of car thieves, and enhancing the sense of security among urban drivers have become challenging challenges for urban public security and traffic management departments.

[0003] In the existing technology, most electric vehicles use a U-shaped lock structure, which is inconvenient to carry and the lock core is easily damaged and easily pried open. In addition, some new electric vehicles cannot use the U-shaped lock.

[0004] In the prior art, most of the lock core structures are latch-type, which cannot generate force on the tire. U-shaped locks cannot be used on some electric vehicles, and U-shaped locks are prone to damage the wheel axle. Summary of the Invention

[0005] The technical problem to be solved by the present invention is the anti-theft and safety issues of electric vehicle parking. U-shaped locks cannot be used due to the limitations of the electric vehicle's wheels, thus failing to exert force on the tires. Existing locks also damage the wheel axles. The present invention provides a wedge-shaped parking lock for electric vehicles to solve the above problems.

[0006] The present invention is achieved through the following technical solutions:

[0007] A wedge-shaped parking lock for an electric vehicle comprises a mechanical column for limiting the position of a tire and a wedge-shaped fastener arranged at the upper end of the inner side of the mechanical column;

[0008] Furthermore, the wedge-shaped fastener has two states: a first state in which it is embedded in the mechanical column; a second state in which it clamps the wheel hub after mechanical transmission; the wheel hub and the tire belong to the same electric vehicle wheel; and in the second state, the contact position between the wedge-shaped fastener and the wheel hub is at the lower half of the wheel axle.

[0009] Furthermore, the two mechanical columns are vertically fixed on the ground, and a groove for limiting the wheel of the electric vehicle is formed in the middle. The wedge-shaped fastener is a wedge-shaped structure, and the wedge-shaped structure is an inverted triangle shape. The two wedge-shaped fasteners on the inner sides of the left and right mechanical columns generate stress through the contact surface with the lower half of the wheel hub on both sides of the wheel in the second state. The wedge-shaped fastener straightens the wheel, and the contact surface is the fitting surface between the inclined surface of the wedge-shaped fastener and the inclined surface of the wheel hub.

[0010] Furthermore, it also includes an auxiliary bracket, which is welded to the lower part of the outer side of the mechanical column. The auxiliary bracket adopts a triangular structure and is made of hard alloy material.

[0011] Furthermore, it also includes a pressure sensor, which is set on the ground at a middle position between the two mechanical columns. When the pressure sensor is subjected to force, the wedge-shaped fastener enters the second state.

[0012] Furthermore, the outer side of the wedge-shaped fastener is wrapped with a layer of hard rubber, and the outer side of the hard rubber has a pattern.

[0013] Based on the above technical solutions, when an electric vehicle enters the electric vehicle parking lock, the wheel pressure acts on the pressure sensor under the synthetic rubber pad, and the wedge-shaped fastener enters the second state. The hard rubber layer on the surface of the wedge-shaped fastener fills the gap between the wedge-shaped fastener and the wheel hub. The hard rubber layer has patterns, and the high friction makes it difficult for the wheel to slip out. The two mechanical columns limit the wheel on the left and right, and the wedge-shaped fastener straightens the wheel, so that the wheel will not be unbalanced.

[0014] The wedge-shaped fastener invented by the present invention matches the wheel hub of the tire in terms of the inclination angle of the surface. The inclined surface of the wedge-shaped fastener and the inclined surface of the tire wheel hub fit tightly together, increasing the contact area of ​​stress, thereby increasing the friction. A hard rubber layer is present between the two inclined surfaces, which effectively increases the static friction coefficient. It can both lock and limit the tire of the electric vehicle, and it solves the problem that the wheels of some existing electric vehicles cannot use the pin-type U-lock structure, and solves the problem that the existing U-lock damages the wheel axle.

[0015] The present invention has the following advantages and beneficial effects:

[0016] The present invention adopts a synthetic rubber pad to ensure long-term stable use of the pressure sensor.

[0017] The present invention adopts the hard rubber layer and the pattern on the hard rubber layer to increase the friction force, so that the wheel is not easy to slip out.

[0018] The present invention adopts two mechanical uprights to limit the wheel on the left and right sides, so that the wheel will not be unbalanced.

[0019] The present invention adopts a wedge-shaped fastener, so that the fixing position is on the wheel hub of the lower half of the wheel, which is not easy to damage the wheel and effectively limits and locks the wheel. BRIEF DESCRIPTION OF THE DRAWINGS
