Description

wireless charging watch

technical field

The utility model relates to a watch, in particular to a watch with a rechargeable battery.

Background technique

When the rechargeable battery used in the electronic watch is exhausted and needs to be recharged, it is usually taken out and placed in a charger for charging. In this way, the watch cover needs to be opened frequently, which is troublesome. There is a watch with a rechargeable battery, which can be directly inserted into a special charger connector to charge the battery, and the operation is simple, but in this way, it is necessary to set a perforation on the watch body, and there will be a problem of how to waterproof the perforation. Especially for diving watches, frequent opening of the watch cover or perforation of the watch body will cause a decrease in the sealing effect, which can easily lead to serious consequences that cannot be used normally. Therefore, how to simplify the recharging steps and ensure safe use has become an urgent problem to be solved.

Contents of the invention

The purpose of the utility model is to provide a watch that can be charged wirelessly, which can simplify the steps of recharging the rechargeable battery, without taking out the battery, and without destroying the structure of the watch body, causing other problems, and is safe and reliable to use.

The technical solution of the utility model is: a watch that can be charged wirelessly, including a rechargeable battery installed in the base, and a wire groove is arranged around the outer wall of the base, and a coil connected with the rechargeable battery is wound in the wire groove.

The coil is set around the rechargeable battery, which is equivalent to a secondary coil, which can sense the current change of the main coil of the external wireless charging charger, and generate a charging current in the secondary coil, which is directly provided to the rechargeable battery without taking it out. The rechargeable battery will not be damaged and can make full use of the internal space of the existing watch body without adding additional parts and is convenient to use.

As an optimized solution, it is also equipped with a charging monitoring circuit connected to the rechargeable battery, which can monitor the state of the rechargeable battery, and prevent the rechargeable battery from being damaged due to overcharging or being used when it is not fully charged.

The horizontal section of the base is quadrilateral or circular, which can adapt to existing watch bodies of different shapes and increase the scope of application.

The utility model has the advantages that the structure is relatively simple, the internal space of the existing watch body can be fully utilized, the charging is convenient, the battery does not need to be taken out, the watch body structure will not be damaged, and the use is safe and reliable.

Detailed ways

Embodiment: Referring to Fig. 1, a wireless charging watch is provided with a liquid crystal display 1, a circuit board 2, a metal buckle 3, a rear support 4, a rechargeable battery 8 and The base 9, wherein the circuit board 2 is provided with a jack 5, the corresponding position of the base 9 is provided with a column 10 that can be inserted into the jack 5, the metal buckle 3 is provided with a lock 6, and correspondingly on the outer wall of the rear bracket 4 There is a protruding part 7 which can cooperate with the buckle 6, a fixing hole 13 corresponding to the socket 5 is provided on the inner wall of the rear bracket 4, and a wire groove 11 is provided around the outer wall of the base 9. During assembly, the rechargeable battery 8 is placed in the base 9, the fixing hole 13 of the rear bracket 4 passes through the column 10, so that the rear bracket 4 is fixed on the top of the rechargeable battery 8, and the jack 5 of the circuit board 2 passes through the column 10, so that the circuit The board 2 is fixed on the rear support, the liquid crystal display 1 is placed on the circuit board 2, the metal buckle 3 is placed outside the liquid crystal display 1, and the lock 6 on it cooperates with the protrusion 7 on the outer wall of the rear support 4, and the The liquid crystal display screen 1 is fixed, thus the connection is completed. Wherein the connection between the rechargeable battery 8 and the circuit board 2 is a prior art, and will not be repeated here.

Referring to Figures 2, 3, 4 and 5, the wire slot 11 is wound with a coil 12 connected to the rechargeable battery 8, which is equivalent to a secondary coil, and the horizontal section of the base 9 is quadrilateral, which is suitable for a square watch body, and can also be It is round to fit a round watch body, but no matter what shape it is, the coil is wrapped around the outside of the base. The circuit board 2 is provided with a charging monitoring circuit connected to the rechargeable battery 8, which can be an existing existing circuit, and will not be described in detail here.

The above detailed description is a specific description for one of the feasible embodiments of the present utility model. This embodiment is not intended to limit the patent scope of the present utility model. Any equivalent implementation or change that does not deviate from the utility model shall include within the patent scope of this case.
