Abstract

The utility model relates to a get-off power failure prompt device for electric bicycle. The get-off power failure prompt device comprises a spring switch which is installed at the rear end of a saddle and can be closed when a damping spring returns completely. The spring switch is in series with a buzzer, a series branch of the buzzer is in parallel with a driving motor of the electric bicycle to be connected in a power supply circuit of the whole electric bicycle, the spring switch is installed on a saddle support beam and comprises a casing, a compression spring is arranged at the bottom end in the casing, a telescopic rod is positioned on the compression spring, the telescopic rod extends out of the casing, the extending-out end of the telescopic rod is connected with the bottom of the saddle, a metal ring capable moving up and down along the with telescopic rod is sleeved at the bottom of the inner end of the telescopic rod, and two switch contacts capable of being connected and disconnected through up-and-down movement of the metal ring are positioned on opposite sides of the upper portion of the casing. The get-off power failure prompt device uses height change of the tail end of the saddle when a rider gets on and gets off to trigger the buzzer to give out alarm to remind the rider of closing a power supply timely when the rider gets off, avoids accidents caused by opening the power supply by accident and is simple in structure and convenient to install.

Description

A kind of Electrical Bicycle outage suggestion device of getting off

Technical field

The utility model relates to Electrical Bicycle, a kind of specifically Electrical Bicycle outage suggestion device of getting off.

Background technology

Electrical Bicycle becomes important walking-replacing tool gradually, and it relies on motor-driven, and motor provides electric power by vehicle-mounted storage battery.Following problem in the use of Electrical Bicycle, occurred: people forget PTO Power Take Off through regular meeting when leaving Electrical Bicycle, on the one hand the meeting consumes electric power; On the other hand, because controlling of Electrical Bicycle is very simple, rotary carriage is advanced promptly driving car body a little, as if PTO Power Take Off not, other people especially child touch handlebar because of carelessness, can cause major accident; In addition, oneself has descended vehicle seat the cyclist, also rotary carriage handle because of carelessness during go-cart, and also can cause the accident if there are obstacle or other pedestrians in the place ahead this moment; At last, if PTO Power Take Off and leave and also might cause vehicle to lose not.What the cyclist got off the unique change of back battery-driven car is the height of vehicle seat rear end, and bottom, vehicle seat rear end is provided with damping spring, and damping spring is installed on the vehicle seat support beam of below-seat; Man-hour is arranged on vehicle seat; Damping spring shrinks, and the vehicle seat rear end is forced down, when the people gets off; Damping spring resets, and the vehicle seat rear end is elevated.To sum up, if can utilize force down and the raise state of vehicle seat rear end before and after the people gets off to trigger warning device prompting PTO Power Take Off, will avoid the generation of above-mentioned variety of issue.

The utility model content

The technical matters that the utility model will solve provides a kind of Electrical Bicycle outage suggestion device of getting off; This device utilizes vehicle seat when damping spring resets fully, to trigger annunciator; Thereby PTO Power Take Off when reminding on vehicle seat nobody has been avoided because of power-on is accidents caused because of carelessness.

For solving the problems of the technologies described above; The get off constructional feature of outage suggestion device of the Electrical Bicycle of the utility model is to comprise being installed in the vehicle seat rear end and closed jack when the damping spring of vehicle seat resets fully; Be electrically connected with the buzzer phone that is installed on the car body with jack; Buzzer phone and jack are formed a series connected branch road, and this series arm is parallelly connected with the drive motor of Electrical Bicycle to be linked in the current supply circuit of whole Electrical Bicycle.

Said jack is installed in the vehicle seat support beam that below-seat is used to install damping spring; Jack comprises housing; The bottom is provided with compression spring in the housing, and compression spring is provided with expansion link, and expansion link stretches out housing and its overhanging end is connected with the vehicle seat bottom; The inner bottom of expansion link is set with can follow the becket that expansion link moves up and down, and relative both sides, housing top are provided with through moving up and down of becket and realize conducting and open circuited two switch contacts.

The beneficial effect of the utility model is: man-hour is arranged on vehicle seat, and damping spring shrinks, and the vehicle seat rear end is forced down; This moment, jack broke off, and when the people got off, damping spring resetted; The vehicle seat rear end is elevated, this moment vehicle seat to drive jack closed, if cyclist's PTO Power Take Off not; The then current supply circuit conducting of buzzer phone, buzzer phone are sent alerting signal and are reminded cyclist's PTO Power Take Off, have avoided because of forgetting that PTO Power Take Off causes unnecessary trouble; Spring adopts top and vehicle seat rear end bonded assembly retracting rods becket, and when raised the vehicle seat rear end, becket triggered simple and reliable for structure at most significant end and conducting two switch contacts.The utility model utilizes the height change of vehicle seat rear end when the people gets on or off the bus to trigger buzzer warning, reminds cyclist's timely PTO Power Take Off of getting off, avoided because of power-on is accidents caused because of carelessness, and simple in structure, easy for installation.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the structure for amplifying scheme drawing at Fig. 1 medi-spring switch place.

The specific embodiment

With reference to Fig. 1; Get off a kind of embodiment of outage suggestion device of the Electrical Bicycle of the utility model is to comprise being installed in vehicle seat 1 rear end and closed jack 3 when the damping spring 2 of vehicle seat 1 resets fully; Be electrically connected with the buzzer phone 5 that is installed on the car body with jack 3; Buzzer phone 5 is formed a series connected branch road with jack 3, and the drive motor of this series arm and Electrical Bicycle 4 is parallelly connected to be linked in the current supply circuit of whole Electrical Bicycle.As shown in Figure 1, vehicle seat 1 is installed on the car body through vehicle seat support beam 10, and damping spring 2 is installed in vehicle seat support beam 10 rear ends; On vehicle seat 1, sit man-hour, damping spring 2 shrinks, and vehicle seat 1 rear end is forced down; When on the vehicle seat 1 nobody the time, damping spring 2 resets, vehicle seat 1 rear end is elevated.The drive motor 4 of Electrical Bicycle is supplied power by storage battery 6, and in current supply circuit, is serially connected with source switch 7.Series arm that buzzer phone 5 and jack 3 are formed and the two ends that are connected to drive motor 4.When the cyclist gets off when forgetting PTO Power Take Off switch 7, whole current supply circuit has electric current to pass through, and the damping spring 2 of vehicle seat 1 rear end resets, jack 3 closures, and the branch road energising of buzzer phone 5, buzzer phone 5 sends alerting signal and reminds PTO Power Take Off switch 7.The installation site of buzzer phone 5 can be installed in the stowed position of car body, for example can be installed in the cavity of vehicle seat 1 bottom.
