Description

Technical Field

[0001] The utility model relates to a parking mechanism for an electric vehicle, and more specifically, mainly relates to a labor-saving parking rear support for an electric vehicle. Background Art

[0002] Due to the limitations of the front and rear wheel structures of electric bicycles, they may tip over when parked. Therefore, it is necessary to install a parking mechanism on the rear side to assist the electric bicycle to be parked stably. The currently commonly used parking rear support uses a wide bottom support frame to support the rear wheel, thereby forming a triangular support structure with the front wheel to ensure stable parking. However, this type of rear support mechanism mainly relies on manpower to lift the entire vehicle and then put down the support mechanism when parking. Since the electric vehicle is equipped with a battery, its own weight is large, which makes the parking process more laborious. Therefore, it is necessary to study and improve the structure of the parking rear support of this type of electric vehicle. Utility Model Content

[0003] One of the purposes of the present invention is to provide a labor-saving parking rear support for an electric vehicle in view of the above-mentioned shortcomings, so as to solve the technical problems that the rear supports of similar electric vehicles in the prior art are limited by their own structures and the parking process is relatively laborious due to the heavy weight of the electric vehicle.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] The utility model provides a labor-saving parking rear support for an electric vehicle, comprising a fixing plate, a support frame mounted on the fixing plate, the support frame being U-shaped, and the upper parts on both sides are movably connected to the respective fixing plates, a pedal limiting plate is mounted on the upper part of at least one side of the support frame, a torsion spring is mounted between the pedal limiting plate and the corresponding fixing plate, a transverse roller shaft is provided on the front side of the bottom of the support frame, a roller body is mounted on the roller shaft, and the roller body is used for rolling contact with the parking surface.

[0006] Preferably, a further technical solution is: two roller shafts are provided on the front side of the bottom of the support frame, respective roller bodies are mounted on the roller shafts, and the wheel diameters of the two roller bodies are equal.

[0007] A further technical solution is that a flat supporting portion is provided on the rear side of the bottom of the supporting frame.

[0008] A further technical solution is: a reinforcing plate is installed at the connecting position between the fixed plate and the support frame, the fixed plate is also provided with an arc-shaped limit groove, the reinforcing plate is provided with a sliding pin, the sliding pin is inserted into the arc-shaped limit groove, and the arc-shaped limit groove is used to make the support frame swing up and down within the travel range of the sliding pin.

[0009] A further technical solution is: the fixing plates are used to be fixed on both sides near the rear wheel axle of the electric vehicle.

[0010] A further technical solution is: the torsion spring is installed on the rotating shaft between the fixing plate and the upper parts of both sides of the support frame, and between the pedal limiting plates.

[0011] Compared with the prior art, one of the beneficial effects of the utility model is that by adding a roller on the front side of the bottom of the support frame, the roller can roll in contact with the parking surface, thereby reducing the friction between the front side of the bottom and the ground during the downward swing of the support frame, and the support frame can be lowered to a predetermined position without lifting the entire vehicle.

[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] refer to Figure 1 and Figure 2As shown, one embodiment of the utility model is a labor-saving parking rear support for an electric vehicle, comprising a fixing plate 1, which is a fixed support structure, and is generally fixedly installed on both sides near the rear wheel axle of the electric vehicle when in use, and a support frame 2 is installed on the fixing plate 1, and the support frame 2 is U-shaped as shown in the figure, and the upper parts of both sides of the support frame 2 are respectively movably connected with their respective fixing plates 1, and the connection method between the two can adopt a pin shaft movably connected to facilitate the rotation of the support frame 2 on the fixing plate 1; at the same time, a pedal limiting plate 3 is installed on the upper part of at least one side of the support frame 2, and the pedal limiting plate 3 can drive the aforementioned support frame 2 to swing up and down on the fixing plate 1 along the aforementioned pin shaft as a whole, and a torsion spring is installed between the pedal limiting plate 3 and the corresponding fixing plate 1, and the torsion spring can fix the support frame 2 at a predetermined support position and a stowed position. More importantly, a horizontal roller shaft 4 is also required to be set on the front side of the bottom of the aforementioned support frame 2, and then a roller body 5 is movably installed on the roller shaft 4, and the roller body 5 is used to roll in contact with the parking surface. In order to increase the stability of the support frame 2 behind the roller body 5, two roller shafts 4 can be set on the front side of the bottom of the support frame 2. The two roller shafts 4 are respectively at the same position as the corresponding side of the bottom of the support frame 2. Then, a respective roller body 5 is installed on each roller shaft 4, and the wheel diameters of the two roller bodies 5 are equal and the same size. The two roller bodies 5 cooperate with each other to improve the stability of the rear support of the improved parking rear support. Furthermore, a flat support part can be adaptively set on the rear side of the bottom of the above-mentioned support frame 2. The support part cooperates with the above-mentioned two roller bodies 5 to further ensure the stability of the support of the support frame 2 in the parking state.

[0018] In this embodiment, a roller 5 is added to the front side of the bottom of the support frame 2 so that the roller 5 can roll in contact with the parking surface, thereby reducing the friction between the front side of the bottom and the ground during the downward swing of the support frame 2. The support frame can be lowered to a predetermined position without lifting the entire vehicle, thereby achieving labor-saving parking.

[0019] According to another embodiment of the present invention, Figure 1 and Figure 2As shown, in order to facilitate the control of the stroke of the above-mentioned support frame 2 swinging up and down, a reinforcing sheet 6 can also be installed at the connection position between the fixed sheet 1 and the support frame 2, and the reinforcing sheet 6 is fixed on the support frame 2, and then an arc-shaped limiting groove 7 is added at the corresponding position of the fixed sheet 1. The aforementioned reinforcing sheet 6 also needs to be designed with a corresponding sliding pin (not shown in the figure). The aforementioned sliding pin is inserted into the arc-shaped limiting groove 7, so that the support frame 2 can only swing up and down within the stroke range of the sliding pin. In this embodiment, the above-mentioned torsion spring can be installed on the rotating shaft between the fixed sheet 1 and the upper part of both sides of the support frame 2, and between the pedal limiting sheet 3. To ensure the stability of the support frame 2 supporting position and the stowed position. The aforementioned torsion spring is not shown in the figure. Since the torsion spring can be purchased on the market, and the structure of the torsion spring for the position control of the rotating part is also relatively conventional, and the same type of electric vehicle parking rear support also uses the matching structure of the pedal limiting sheet 3 and the torsion spring, the installation position of the torsion spring and the limiting principle are no longer described in detail, and the purpose of the utility model is not to this.

[0020] refer to Figure 1-3 As shown, in the above preferred embodiment of the utility model, in actual use, the fixing plate 1 is fixed on both sides near the rear wheel axle of the electric vehicle. When parking is required, the support frame 2 is moved along the pedal limit plate 3. Figure 3 The direction shown by the arrow changes, so that it reaches the parking position, and is kept in the parking position under the action of the torsion spring; in this process, when the support frame 2 swings downward, the roller body 5 rolls along the ground, reducing the friction between the front side of the support frame 2 and the ground, and then only the whole vehicle needs to be slightly lifted up to use the roller 5 to drive the support frame to quickly reach the supporting position, which is more labor-saving to use.
