Problems solved by technology

[0003] The disadvantage of the above-mentioned traditional double supports is that it is time-consuming and labor-intensive to use, especially for heavy-duty electric vehicles or motorcycles, and generally a single user cannot lift the rear end of the vehicle
[0005] The disadvantage of the above-mentioned existing electric double support legs is that the casing used is relatively large in volume, which is not conducive to being arranged at the bottom of the frame of an electric vehicle or motorcycle, thereby limiting its popularization.
Secondly, its structure is complicated, the cost is high, and the meshing of the tooth surface of the kick rod and the rack, the torsion spring, etc. are prone to failure, resulting in low reliability; The aforementioned kick rods hinged with the bottom ends of each strut tend to swing to the inside, thus causing the vehicle to roll over

Embodiment 1

[0028] See Figure 1-4 , the electric double stand of the present embodiment comprises: a pair of cylinders 4 that are respectively bearing matched to the two ends of a shell 2, and screw rods 9 fixed on the central axis in each cylinder 4, respectively connected to the pair of cylinders 4. A pair of legs 3 screwed to the screw rod 9 in the cylinder 4; a limiting mechanism for limiting the rotation of each leg 3 relative to the housing 2 is provided between the pair of legs 3 and the housing 2; the one The cylindrical body 4 is synchronously connected with a leg motor 1 .

[0029] The pair of cylinders 4 are respectively fixed with gears 10, and each gear 10 is synchronously connected with the leg motor 1 through a synchronous belt 6, so as to drive each cylinder 4 to rotate around its central axis.

[0030] In order to save space, the foot motor 1 and the gears 10 are arranged in the housing 2; the housing 2 is also provided with a tensioning wheel 5 for tensioning the synch...

Embodiment 2

[0042] An electric vehicle, the electric vehicle includes a lock; the lock is the electric double support in the above-mentioned embodiment 1, and the electric double support is arranged at the bottom of the middle front part of the rear fork of the electric vehicle or motorcycle. That is to say, as long as the electric double support legs are in the propped state, the electric car or motorcycle cannot be ridden, that is, the car lock function is realized, and the car lock does not have the problem of being pried open.

Embodiment 3

[0044] An electric vehicle using the electric double legs of the above-mentioned embodiment 1, including: a power key switch, the power key switch includes: a neutral position suitable for cutting off the power supply of the legs motor 1 and the main motor of the electric vehicle, suitable for only The driving gear that connects the power supply of the main motor of the electric vehicle is suitable for only connecting the parking gear of the power supply of the foot motor 1, so as to avoid misoperation.

[0045] The electric vehicle also includes: a sensor for detecting whether the wheel where the main motor of the electric vehicle is located is rotating, and the sensor is connected to the controller of the electric vehicle; when the controller detects that the wheel stops through the sensor, and When the power key switch is in the parking position, the power supply of the motor for the legs is turned on, so as to avoid the danger caused by the downward displacement of the legs...

Abstract

The invention relates to an electric double frame brace, which comprises a pair of barrels in bearing fit with two ends of a shell, screw rods fixed on the central axes in the barrels, and a pair of frame braces connected with the screw rods in the pair of barrels through threads respectively. A limiting mechanism for limiting the rotation of each frame brace relative to the shell is arranged between the pair of frame braces and the shell. The pair of barrels is in synonymous transmission connection with a frame brace motor. The electric double frame brace has the beneficial effects of simple structure, low cost and convenient assembly. The process of supporting a bicycle can be completed electrically, man power is not required, the supporting speed is faster (generally within 5 minutes), the double frame brace is suitable for supporting a load of 300 Kg, and the use by a user is facilitated.

Description

technical field [0001] The invention relates to a supporting device for an electric vehicle or a motorcycle, in particular to an electric double brace and an electric vehicle or motorcycle using the brace. Background technique [0002] The supporting devices for electric vehicles or motorcycles in the prior art are generally diagonal braces or double braces with tension springs, wherein the rear end of the electric vehicle or motorcycle needs to be lifted when the double braces are used, and then Use your feet to push the bipods into the hem position. [0003] The disadvantage of the above-mentioned traditional double legs is that it is time-consuming and labor-intensive to use, especially for heavy-duty electric vehicles or motorcycles, and generally a single user cannot lift the rear end of the vehicle. [0004] Chinese patent document CN 102923210 A relates to an electric double support leg, which includes: a screw rod, a motor connected to the screw rod, a beam threaded...
