The invention discloses a warning device controlling a turn light to flash by positive signals of an alarm, which consists of a battery, a relay No.2, a diode, a line No.1 and a line No.2. the anode and cathode power lines of the warning device are connected to the anode and cathode of a storage battery of an original car; at the normal working state, the storage battery of the original car is responsible for charging the battery; when the anode line or cathode line of the power supply is cut off, the relay No.2 is disconnected; the electric power of the battery can be transmitted to No. 4 pin of a control chip directly; the control chip conducts relay No.1 and then the turn light is lightened, so that the warning function of switching on the turn light is realized when the power of the original car is cut off at the same time.

The application discloses a vehicle display method, device, electronic equipment and storage medium. The method includes: obtaining the status information of each vehicle within the preset range; determining the target vehicle that needs to be warned according to the status information; assigning a group of vehicle models to the target vehicle, and the number of models in the group of vehicle models is not less than two; Among the vehicle models, the first type attributes of each vehicle model are the same, and the second type attributes of each vehicle model are different from each other; according to the first type attributes and second type attributes of the group of vehicle models, in the preloaded high-precision The vehicle instance of the target vehicle is displayed based on the first type of attribute, and the preset warning effect of the vehicle instance is realized through the second type of attribute. This technical solution can not only alternately display the second type of attributes such as different colors for the vehicles that need to be warned, but also reuse the first type of attributes that can be used by all vehicle models in the group of vehicle models, saving resources and improving high-precision The efficiency of map rendering and display.

The invention discloses an electric power overhauling toolbox, which comprises a toolbox body and two fixed plates arranged at the inner upper and lower ends of the toolbox body respectively, wherein a tool fixing plate is arranged between the two fixed plates; an end cover is arranged on the toolbox body; sliding chutes are formed in the upper and lower ends of the side, far away from the end cover, of the toolbox body respectively; cross rods are arranged in the sliding chutes, and can slide along the sliding chutes; vertical rods are connected to the tail ends of the two cross rods; external infrared transmitters and external infrared receivers are arranged at the two ends of the sliding chutes respectively; a controller is arranged on the inner side of the toolbox body; the external infrared transmitters and the external infrared receivers are connected with the controller through lines respectively. According to the electric power overhauling toolbox, the external infrared transmitters and the external infrared receivers are used for detecting whether a person enters a dangerous region from the outside or not, and an internal infrared transmitter and an internal infrared receiver are used for detecting whether a person illegally takes a tool or not.

The invention discloses a bicycle lock provided with alarm lights. The bicycle lock comprises two lock legs, hinge blocks, two lock arms and a lock head, wherein each hinge block is hinged to one end of the corresponding lock leg, each lock arm is hinged to the other end of the corresponding lock leg, the lock head is hinged to the free end of one of the lock arms, the free end of the other lock arm is provided with a lock hole which can be locked with the lock head in a buckled mode, planes between the lock legs and the lock arms are in back-to-back arrangement so that the lock legs and the lock arms can be folded and drawn close in a paired mode and can be inserted into a containing sleeve with the front side and the rear side hollowed out, and the alarm lights which are arranged on the front sides, in the opposite directions, of the lock legs and the lock arms respectively in the length direction. The invention further discloses a bicycle lock provided with an alarm light. The bicycle lock comprises two lock legs and a lock arm, wherein the two ends of the lock arm are connected with the lock legs, and one end is connected through a lock head. The lock legs and the lock arm are unfolded to form a loop-back structure, so that a bicycle is locked; the lock legs are stretched to form the triangular alarm light in combination with the lock arm, when the bicycle is ridden at night, the lock can be inserted into a containing sleeve, and the alarm light is turned on and can be unfolded and hung at the side or the back of a bicycle body, so that the alarm effect is achieved.

The invention belongs to the technical field of shared bicycles, and in particular relates to a crank pedal mechanism with a side warning mechanism for shared bicycles, which includes a driving disc, a fixed shaft, two sets of cranks and two pedals, and the fixed shaft is coaxially fixedly connected to the In the driving disc, two cranks are respectively fixedly installed at both ends of the fixed shaft, and the pedals are rotated and installed at the ends of the cranks. The lower end of the pedals is fixedly connected with a wedge-shaped mounting seat, and a permanent magnet block is fixedly installed in the mounting seat. Two The magnetic poles of the permanent magnet blocks are the same and are all inclined to the same direction; the fixed shaft is hollow, and the fixed shaft is provided with a light-emitting mechanism. The light-emitting mechanism includes a generator coil, a rectifier connected in series on the generator coil, and an LED lamp. In the present invention, by setting the mounting base, the permanent magnet block and the generator coil, the positions of the two permanent magnet blocks and the generator coil are changed all the time during the continuous movement of the permanent magnet block with the pedals, so that the generator coil generates an induced current to the LED. Power supply can realize the warning effect on the side of the bicycle.
