Description

Technical Field

[0001] This utility model belongs to the field of two-wheeled vehicle parking technology, specifically an adjustable-width electric vehicle parking limit device. Background Technology

[0002] With the increasing number of cars in my country, parking problems in cities are becoming more and more prominent, especially in densely populated areas where parking spaces are even scarcer. As a result, electric vehicles have become the best choice for people to travel short distances within the city.

[0003] A search revealed a public disclosure (CN202463974U) for a cam-type parking bracket for two-wheeled motorcycles and electric vehicles. The bracket utilizes components from traditional rear brackets, including fasteners, bushings, a main frame, and tension springs. It modifies the original rear bracket legs of a two-wheeled vehicle by installing two cam-type support legs, with an integral foot lever welded to one leg. When parking, pressing the integral foot lever causes the cam-type support legs to rotate clockwise, their front arcs touching the ground to form a fulcrum. This effectively shortens the distance between gravity and the fulcrum while lengthening the distance between pressure and the fulcrum, reducing effort by more than half compared to traditional brackets. The cam's radius of curvature gradually increases, resulting in near-uniform speed during the vehicle's upward and backward movement, leading to smooth lifting and minimal recoil.

[0004] Currently, existing technologies lack a quick and convenient way to limit the movement of the sides of two-wheeled electric vehicles of different models and widths.

[0005] Therefore, an adjustable-width electric vehicle parking limit device is proposed to address the above problems. Utility Model Content

[0007] The technical solution adopted by this utility model to solve its technical problem is: an adjustable width electric vehicle parking limit device, comprising a support plate, wherein a groove is provided on the surface of the support plate, and a sliding limit mechanism is provided in the groove;

[0008] The sliding limiting mechanism includes a multi-groove track column disposed at the bottom of the groove and an actuator surrounding the multi-groove track column. The actuator performs sliding and braking on the multi-groove track column.

[0009] The multi-groove track column includes a sliding groove and a braking groove arranged sequentially from top to bottom;

[0010] A brake is provided on one side of the actuator;

[0011] The actuator is equipped with a limit rod, which can be moved to different positions to achieve different width limits.

[0012] Preferably, the actuator is provided with a sliding end and a braking end at the position of the multi-groove track column, respectively, and corresponds to the sliding groove and the braking groove.

[0013] Preferably, the brake is used to control the locking and unlocking of the braking end. In the locked state, the braking end extends and engages with the brake groove, and in the unlocked state, the braking end retracts.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Specific implementation examples are given below.

[0029] Please see Figures 1-6 This utility model provides an adjustable-width electric vehicle parking limiting device, including a support plate 1. The surface of the support plate 1 has a groove 2, and a sliding limiting mechanism is provided in the groove 2. The sliding limiting mechanism includes a multi-groove track column 30 disposed at the bottom of the groove 2 and an actuator 40 covering the periphery of the multi-groove track column 30. The actuator 40 slides and brakes on the multi-groove track column 30. The multi-groove track column 30 includes a sliding groove 31 and a braking groove 32 arranged vertically. A brake 43 is provided on one side of the actuator 40. A limiting rod 6 is provided on the actuator 40. Different width limits are achieved by moving the actuator 40 to different positions. It is mainly used for width limiting when parking electric vehicles and is suitable for electric vehicles with different wheelbases, such as electric bicycles and electric motorcycles.

[0030] Furthermore, such as Figure 1 , Figure 3 and Figure 5As shown, the support plate 1 is made of Q235 steel plate, integrally stamped, with a thickness of 10-50mm. It can be used directly as the bottom surface or as the base plate of double-layer or multi-layer electric vehicle parking garages. Its surface is treated with sandblasting and electrostatic spraying (coating thickness ≥60μm), providing rust resistance and wear resistance. The support plate 1 is 1200mm long and 600mm wide. A groove 2 is formed along the length of its surface, with a groove width of 120mm and a depth of 50mm, to accommodate the sliding limit mechanism and provide motion guidance. The inner walls of both sides of the groove 2 are symmetrically marked with scale markings (unit: cm) for easy and intuitive reading of the adjustment distance of the sliding limit mechanism.

[0031] The sliding limit mechanism includes a multi-groove track column 30 and an actuator 40. The two are slidably connected by clearance fit. The multi-groove track column 30 is a cuboid structure (length 1000mm × width 100mm × height 40mm), made of 6061 aluminum alloy by CNC machining. Its upper and lower surfaces are respectively provided with sliding grooves 31 and braking grooves 32 along the length direction.

[0032] The sliding groove 31 is located below the multi-groove track column 30. It has a concave cross-section, a groove width of 60mm, and a depth of 15mm. A polytetrafluoroethylene wear-resistant strip (2mm thick) is embedded in the groove to reduce the sliding friction coefficient to below 0.05. The position above the brake groove 32 can play an auxiliary sliding role.

[0033] The brake groove 32 is located above the sliding groove 31, and has evenly distributed engaging protrusions along its length. The protrusions can be flat or serrated (50mm apart). The serrated protrusions are 8mm deep and have a tooth surface inclination angle of 60°, and are used to engage with the brake end 42 to achieve locking. The multi-groove track column 30 is fixed to the bottom of the groove 2 by four M8 expansion bolts, and the distance between both ends and the edge of the bearing plate 1 is 100mm.

[0034] Furthermore, such as Figure 2 and Figure 6 As shown, the actuator 40 is an inverted "U"-shaped frame structure (forged from 45# steel). The inner side of the multi-groove track column 30 is equipped with a sliding end 41 and a braking end 42. The sliding end 41 is a convex slider that matches the sliding groove 31, with a ball bearing (5mm in diameter) embedded at the bottom to achieve rolling friction, ensuring a sliding resistance ≤5N. The braking end 42 is an elastic metal sheet (2mm thick) with a serrated head at its end that matches the groove of the braking groove 32, extending 10mm in its natural state. A handle (150mm in length) is welded to the outer wall of the actuator 40, facilitating the operator to push it along the track.

[0035] The brake 43 is a manual knob type structure, installed on the outer wall of the actuator 40. Internally, it is connected to the brake end 42 via gear transmission. When the knob is rotated clockwise (90° rotation), the gear drives the brake end 42 to extend and engage in the slot of the brake groove 32. At this time, the positive pressure between the brake end 42 and the slot is ≥300N, achieving locking (sliding resistance ≥500N). When the knob is rotated counterclockwise (90° rotation), the gear drives the brake end 42 to retract (retraction ≥12mm), disengaging from the brake groove 32 and unlocking.

[0036] Furthermore, such as Figures 1-4 As shown, an extension column 5 is vertically welded to the top of the actuator 40. The extension column 5 is a seamless steel pipe with a diameter of 50 mm (height of 300 mm), and its top is connected to the limit rod 6 via a flange (diameter of 80 mm).

[0037] The limiting rod 6 is a round tube structure (30mm in diameter and 400mm in length) with a rubber anti-slip sleeve (5mm thick, Shore hardness 60±5A) on its surface to prevent scratching the electric vehicle tires.

[0038] A reinforcing rod 7 is symmetrically welded on both sides of the connection between the heightening column 5 and the limiting rod 6. The reinforcing rod 7 is made of the same material as the limiting rod 6, forming a stable structure at the two connection points. Angle steel (specification 30×30×3mm) can also be used to form a triangular stable structure, so that the bending strength of the limiting rod 6 is ≥2000N.

[0039] Furthermore, such as Figures 1-4 As shown, a front wheel limiting component 8 is welded to the front end of the bearing plate 1 on the side away from the sliding limiting mechanism. It is formed by bending a 10mm thick steel plate or by integrally forming a 20mm-30mm diameter steel pipe.

[0040] The entrance is designed as a flared structure (the opening width gradually decreases from 300mm to 200mm) or a square structure, with a guide roller (50mm in diameter) welded on the inside to facilitate the smooth entry of the electric vehicle's front wheel.

[0041] A limit bar (25mm diameter round steel) is installed at the rear end, 200mm away from the entrance end and 150mm high, to prevent the front wheel from moving too far forward, and works with the sliding limit mechanism to position and park the electric vehicle.

[0042] The working process of this utility model is as follows: When in use, the operator adjusts the limit width according to the following steps: rotate the knob of the brake 43 counterclockwise to the unlock position. At this time, the brake end 42 is retracted, and the actuator 40 can slide freely along the multi-groove track column 30. Measure the distance between the outer sides of the two front wheels according to the wheel track of the electric vehicle to be parked, push the actuator 40 to the appropriate position and read it through the scale mark of the groove 2, so that the distance between the limit rod 6 and the front wheel limit member 8 matches the wheel track of the electric vehicle.

[0043] Rotate the knob of brake 43 clockwise to the locked position. Brake end 42 is inserted into the slot of brake groove 32, and actuator 40 is fixed. The front wheel of the electric vehicle enters from the inlet end of front wheel limiter 8 until the front wheel contacts the limit bar. At this time, the wheels on both sides are blocked by front wheel limiter 8 and limit bar 6 respectively, completing the limited parking. This utility model can be adapted to various electric vehicles with wheel track in the range of 600-1200mm through the adjustable design of sliding limit mechanism. The adjustment accuracy is up to 50mm. The resistance to lateral impact force in the locked state is ≥1000N, which meets the requirements of standardized parking of electric vehicles in public places.
