[0030] Referring to the attached Figures 1-5 , an energy-saving device for an electric vehicle, comprising:

[0031] A grip rod 1, with a limiting plate 2 provided at its inner end; a plurality of card slots 3 are opened in the inner ring of the limiting plate 2;

[0032] A first sleeve 4, sleeved on the grip rod 1, with an annular baffle 5 provided thereon; a plurality of teeth 6 cooperating with the card slots 3 are provided at one end of the first sleeve 4 close to the limiting plate 2, and a force-receiving inclined surface 7 is provided at the end thereof far from the limiting plate 2;

[0033] A second sleeve 8, sleeved on the first sleeve 4, with one end thereof close to the limiting plate 2 abutted against the baffle 5; 4 pressing plates 9 are hinged on the first sleeve 4, and the hinged position is at a position close to the middle of the inner wall of the pressing plate 9; a pressing block 10 corresponding to the position of the force-receiving inclined surface 7 is provided at the end of the pressing plate 9 extending out of the first sleeve 4; an annular positioning plate 11 is further provided at one end of the second sleeve 8 close to the limiting plate 2;

[0034] A grip 12, sleeved on the grip rod 1, with its front end fixed to the positioning plate 11 by bolts; 4 notches 13 corresponding to the positions of the pressing plates 9 are opened on the grip 12, and a rubber pad 14 is provided in the notches 13; one end of the rubber pad 14 is bonded in the notch 13 and the other end is a movable end; a raised rubber block 15 is provided on the upper surface of the movable end of the rubber pad 14.

[0035] A cover plate 21 is provided at one end of the grip 12 far from the limiting plate 2, and an extension section in threaded cooperation with the grip rod 1 is provided at one end of the cover plate 21 facing the limiting plate 2. Screwing the cover plate 21 tightly on the grip rod 1 can also play a role in limiting the grip 12 and preventing the grip 12 from detaching from the grip rod 1.

[0036] In actual use, the user needs to firmly hold the handle 12 with the hand and rotate it to accelerate the electric vehicle to a certain speed and maintain it. At this time, the user can apply pressure to the rubber block 15 protruding from the movable end of the rubber pad 14 on the handle 12 with the thumb or index finger, so that the movable end of the rubber pad 14 is pressed downward into the notch 13, and then pressure is applied to the end of the pressing plate 9 extending out of the first sleeve 4, so that the pressing block 10 below the pressing plate 9 applies pressure to the force-receiving inclined surface 7 at one end of the first sleeve 4. When the force-receiving inclined surface 7 receives downward pressure, it will drive the entire first sleeve 4 to move along the grip rod 1 towards the limiting plate 2, so that the locking teeth 6 enter the corresponding card slots 3, thereby realizing the temporary limitation of the handle 12.

[0037] When the handle 12 is in a temporarily limited state, the user only needs to firmly hold the handle 12 and maintain the pressure on the rubber pad 14, so that the electric vehicle can maintain a constant speed, avoid sudden acceleration or deceleration, and can play an energy-saving effect to a certain extent and extend the battery life.

[0038] In this embodiment, since the handle 12 and the positioning plate 11 on the second sleeve 8 are fixed by bolts, when the user rotates the handle 12, the second sleeve 8 will also rotate accordingly. The first sleeve 4 can rotate and slide on the grip rod 1. There are 2 symmetrically arranged limiting blocks 16 on the annular baffle 5 of the first sleeve 4, and a limiting groove 17 matching the limiting blocks 16 is opened at one end of the second sleeve 8 close to the baffle 5. Therefore, when the second sleeve 8 rotates with the handle 12, it can drive the first sleeve 4 to rotate, which is convenient to change the matching position of the locking teeth 6 and the card slots 3 during the rotation process.

[0039] It should be noted that a return sleeve 18 is provided at one end of the second sleeve 8 close to the limiting plate 2; the return sleeve 18 is in threaded cooperation with one end of the second sleeve 8 close to the baffle 5, and a compression spring 19 is provided inside it; one end of the compression spring 19 abuts against the baffle 5. When the rubber pad 14 at the notch 13 of the handle 12 is not under pressure, the baffle 5 of the first sleeve 4 is under the pressure of the compression spring 19, so that the force-receiving inclined surface 7 of the first sleeve 4 remains in a state below the pressing block 10. At this time, the locking teeth 6 and the card slots 3 are not in contact. When the rubber pad 14 is pressed downward into the notch 13 under pressure, the force-receiving inclined surface 7 receives the pressure of the pressing block 10 below the pressing plate 9, driving the first sleeve 4 to move towards the limiting plate 2, so that the locking teeth 6 enter the corresponding locking teeth 6, realizing the temporary limitation of the handle 12. It should be noted that during actual assembly, after the second sleeve 8 is sleeved on the first sleeve 4, the force-receiving inclined surface 7 needs to be welded and fixed on the first sleeve 4.

[0040] In addition, an annular magnetic block 20 is sleeved on the second sleeve 8; the pressing plate 9 is made of a magnetic material and is attracted by the magnetic force of the annular magnetic block 20. When the pressing plate 9 is not under pressure, one end thereof close to the positioning plate 11 is adsorbed on the annular magnetic block 20; when the pressing plate 9 is under pressure, one end thereof close to the positioning plate 11 will be temporarily lifted; when the pressure on the pressing plate 9 disappears, one end thereof close to the positioning plate 11 will be adsorbed on the annular magnetic block 20 again under the action of the magnetic force.

[0041] For the energy-saving device of the electric vehicle of the present utility model, by providing a rubber pad 14 on the grip 12 that cooperates with the pressing plate 9, the teeth 6 on the first sleeve 4 can be pressed into the slot 3 in the inner ring of the limiting plate 2 on the grip rod 1 when the user tightly holds the grip 12, so as to realize the temporary limitation of the grip 12, keep the electric vehicle running at a constant speed, which is beneficial to energy conservation and extends the endurance; at the same time, when the user relaxes the pressure on the grip 12, the limitation of the grip 12 can be quickly released, which more conforms to the daily use habits of the user, enabling the user to quickly get a response when wanting to decelerate or accelerate, being very practical and having a good market application prospect.

[0042] The foregoing description of the specific exemplary embodiments of the present utility model is for the purposes of illustration and exemplification. These descriptions are not intended to limit the present utility model to the precise forms disclosed, and obviously, many changes and variations are possible in light of the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present utility model and its practical applications, so that those skilled in the art can implement and utilize various different exemplary embodiments of the present utility model as well as various different selections and changes.
