It is simpler in structure, has smaller wheels, and is lightweight and convenient compared to traditional electric bicycles, saving a large amount of social resources. An instrument is installed at the handle of the scooter. The existing electric scooter is started by a button in the instrument and has no power-off lock. When people make a misoperation, it is easy to have a safety accident, and for children, it is even easier to have a safety accident. In addition, when people use an electric scooter, since the load and road conditions are variables, the electrical components in the instrument are often burned out, and even the circuit is short-circuited. Summary of the Invention

[0004] The technical solution adopted by the present invention to solve the above technical problems is as follows: The locked scooter instrument includes an outer cover, a circuit board fixedly installed inside the outer cover, a display screen electrically connected to the circuit board, and an electronic lock for connecting or disconnecting the circuit of the circuit board. The electronic lock is electrically connected to the circuit board. The display screen is fixedly installed at the front end of the circuit board and is arranged on the front surface of the outer cover. An electronic lock installation hole for installing the electronic lock is opened inside the outer cover.

[0005] Among them, the outer cover includes a rear cover and a front cover covering the front end of the rear cover. The rear cover is fixedly installed on the front cover by bolts. The electronic lock installation hole is provided in the rear cover and the front cover, and the electronic lock installation hole is an independent cavity.

[0006] Among them, a flange protrudes forward from the edge of the front surface of the rear cover, and a groove matching the flange is opened on the rear surface of the front cover.

[0007] Among them, a plug fuse is inserted at the rear end of the circuit board.

[0008] Among them, a lock core cover is fixedly sleeved inside the electronic lock installation hole. The electronic lock is sleeved inside the lock core cover. A plurality of first water leakage holes are opened at the rear end of the lock core cover, and a plurality of second water leakage holes are opened at the bottom of the electronic lock installation hole.

[0009] Among them, a wire passing hole for the wire connecting the electronic lock and the circuit board to pass through is opened on the side wall of the lock core cover.

[0010] Among them, a finger hook is installed at the rear end of the outer cover.

[0011] Among them, a magnet is fixedly installed on the side wall of the finger hook, the circuit board is electrically connected to a Hall element, and the magnet faces the Hall element.

[0012] Among them, a fixing seat is fixedly installed at the lower end of the outer cover.

[0013] Among them, a first mounting block is integrally formed at the lower end of the outer cover, a second mounting block is provided at the upper end of the fixing seat, the second mounting block is fixedly installed on the first mounting block by bolts, and a hoop is provided at the lower end of the fixing seat.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. An electronic lock is provided on the instrument of the present invention to connect or disconnect the circuit of the circuit board, which can avoid unnecessary accidents caused by children accidentally touching the button to directly turn on the machine, and improve the safety of the circuit;

[0016] 2. Compared with the traditional finger hook instrument, the present invention changes the self-resetting fuse of the patch components originally arranged in the vehicle body to a mechanical plug fuse arranged in the instrument, and leads all the high-power parts and the parts that need to be protected by the electronic control to the plug fuse. After such a design, the safety part of the entire circuit is controlled by the fuse, which greatly reduces the insecurity of the circuit; at the same time, since the plug fuse is arranged in the instrument, the disassembly and installation for future maintenance and repair are convenient. When the instrument cannot work properly, as long as a person who knows a little about the circuit can check and repair whether the fuse of the instrument circuit part is damaged by himself and can replace the fuse by himself;

[0017] 3. The outer cover of the instrument includes a front cover and a rear cover, and the front cover and the rear cover are hermetically connected through the cooperation of a groove and a flange, which improves the waterproof performance of the instrument, and it is not easy for rainwater to enter the circuit in rainy days and cause a short circuit.

[0032] The locked scooter instrument of the present invention has the following advantages:

[0033] 1. Improved the safety of the whole vehicle: For traditional scooter finger hook meters, simply pressing the power-on button can activate the vehicle's electronic control system. That is to say, as long as the battery has power and the vehicle has no faults, anyone can ride it. After adding an electronic lock, a mechanical key is required to turn on the vehicle's electronic control system, which improves safety and can also avoid unnecessary accidents caused by children accidentally pressing the button to turn on the power directly;

[0034] 2. Increased the upper limit of the current supplied by the meter to the whole vehicle. At the same time, it is convenient for scooter maintenance and improves the stability of the vehicle's electronic control system. Remove the surface-mounted components self-resetting fuses and the triode power components for supplying power to the whole vehicle on the traditional finger hook meter, and all are changed to mechanical plug fuses; Mechanical plug fuses can be manually replaced. Lead all high-power parts and parts that need to be protected by the electronic control to the plug fuses. After such a design, the safety part of the entire circuit is controlled by fuses, greatly reducing the insecurity of the circuit. And we have also made it so that anyone who knows a little about circuits can check and repair it by themselves. If the vehicle comes with tools and spare plug fuses, they can repair it at any time. It is even easier to solve if taken to a repair shop because plug fuses are conventional parts; At the same time, considering the scooter market, taking into account that some consumers install or replace larger-power headlights or other parts that require large current on the scooter, thicker wires can be added to the mechanical key to supply large current to the whole vehicle to prevent the consequences caused by modification. And clearly remind customers at the place where the fuse is replaced on the meter of the fuse specification in amperes of current to prevent unnecessary troubles caused by the fuse specification problem when users use it. In this way, consumers will be safer when using it;

[0035] 3. Because the early meters did not have a mechanical lock or a mechanical plug fuse structure, when the meter could not work properly, ordinary people could not repair it and could only replace the whole meter, which led to spending a lot of unnecessary money and reducing the after-sales cost. If the repair shop did not have meter inventory, the waiting time for repair would be even longer. And mechanical plug fuses are very common, more convenient to buy and have a low cost, which is very beneficial to the people.

[0036] Finally, it should be noted that: The above embodiments only illustrate the technical solutions of the present invention and do not limit it; Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
