Description

Technical Field

[0001] The invention relates to a watch, in particular to an automatic time-correcting watch based on wireless communication. Background Art

[0002] The existing technology of clock synchronization between portable smart devices generally includes two types: hard synchronization and soft synchronization. Soft synchronization is that the controller records the timestamp of the moment when the sensor data is obtained, and hard synchronization is to obtain the timestamp through the PPS+GPRMC data packet method. The hard synchronization method has higher synchronization accuracy, but the system is complex. The soft synchronization process is relatively simple, but the accuracy is not high.

[0003] Electronic timing equipment in the existing technology may also use synchronization methods such as laser vision to automatically adjust the time, but this type of algorithm-controlled time adjustment will increase the circuit complexity of the equipment. In addition, once an error occurs, the core components can only be replaced, which makes repair difficult. Complex algorithms will also increase the burden on the chip, resulting in the accumulation of a large amount of useless data.

[0004] To this end, those skilled in the art have proposed an automatic time-setting watch based on wireless communication, which realizes automatic time setting of the device and ensures accuracy by setting a mechanical structure based on the existing smart watch and combining wireless communication technology. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an automatic time-setting watch based on wireless communication. By setting a reset button on the existing watch and combining wireless communication with a reset mechanism of a mechanical structure to calibrate the watch, the watch time can be confirmed accordingly based on the received feedback signal at twelve o'clock noon every day, and a more accurate time calibration can be performed, thereby avoiding the problem of inaccurate time gradually occurring with the extension of the use time, and also avoiding the problem of complicated time calibration methods used in existing watches.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an automatic time-setting watch based on wireless communication, including a watch body, which includes all the features of existing smart watches and can realize the timing function of existing watches.

[0007] The watch body is provided with a reset button on the inner side, through which the timing program of the watch body can be quickly restarted.

[0008] A carry rod is provided at the rear of the watch body corresponding to the reset button, and a first coil is fixedly provided at one end of the carry rod away from the reset button. The first coil is electrically connected to the closed circuit of the circuit board, and a magnetic field is generated at the first coil through the current in the closed circuit. Under the action of the magnetic field, the carry rod is driven to carry, and the carried carry rod presses against the reset button to realize the mechanical reset of the watch body.

[0009] The closed circuit on the side of the circuit board is also electrically connected to a signal transceiver, which can realize simple signal transmission and reception, and provide a basis for the time adjustment of the watch through wireless communication. On the one hand, it avoids the timing equipment installed on the watch from being damaged at the same time, and on the other hand, it avoids installing too many functions on the watch to affect the portability requirement.

[0010] The signal transceiver receives an external wireless control signal, and the chip controls the on and off of the closed circuit according to the timestamp of the wireless control signal. The first coil generates a magnetic field under the current of the closed circuit to push the carry rod to carry, and the carry rod presses the reset button to reset the watch body, thereby automatically calibrating the time of the watch body.

[0011] Preferably, a buffer pad is fixed to the side of the circuit board, through which a carry space is provided between the watch body and the carry rod, and at the same time can be used as a buffer structure of the watch body to help the watch body resist vibration and reduce losses.

[0012] A mounting arm is fixedly connected to the side of the circuit board corresponding to the carry rod, and the carry rod is slidably arranged on the inner side of the mounting arm. The mounting arm can provide a stable mounting structure for the carry rod and can also guide the carry direction of the carry rod.

[0013] Preferably, a fixing block is threadedly connected to the side of the carry rod, and a spring is provided on the side of the carry rod through the fixing block to press against the side wall of the mounting arm. The fixing block is used for pressing the spring against the side of the carry rod, and the fixing block threadedly sleeved on the side of the carry rod also facilitates the adjustment of the installation position, thereby adjusting the accuracy of the structure and avoiding the problem of loss of accuracy due to deformation of the mounting arm.

[0014] Preferably, the end of the mounting arm is fixedly connected to a U-shaped block, the advancement rod passes through the side wall of the U-shaped block and is slidably connected thereto, and the fixed block is arranged on the inner side of the U-shaped block.

[0015] The two cantilevers of the U-shaped block are used to guide the installation of the advance rod, and it is convenient to limit the fixed block and to facilitate the threaded installation of the fixed block on the side of the advance rod. Even if the installation arm is deformed, the trigger accuracy calibration can be achieved by adjusting the installation position of the fixed block on the side of the advance rod.

[0016] Preferably, a battery core is fixed on the side of the circuit board and inside the first coil. When current passes through the first coil, the battery core will have magnetic force, and the magnetic force will apply force to the carry rod.

[0017] The carry rod is installed coaxially with the battery core, and a second coil is sleeved on the outer side of the carry rod. The second coil is also connected to the closed circuit on the circuit board, and the second coil and the first coil are reverse windings.

[0018] The first coil and the second coil of the reverse winding generate opposite electric fields after the circuit is connected, and the carry rod and the battery core located on the inner side of the two respectively become electromagnets with opposite magnetic poles repelling each other. Under the action of the repulsive force, the carry rod compresses the spring seat to move forward, and the carry rod acts on the reset button to restart the timing of the watch body, thereby completing the mechanical time adjustment of the watch body combined with wireless communication.

[0026] 2. In the automatic time-correcting watch based on wireless communication, a circuit board is arranged at the rear of the watch body corresponding to the reset button.

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The embodiment of the present invention discloses an automatic time-correcting watch based on wireless communication;

[0038] According to the attached Figure 1 As shown, the watch body 1 includes all the features of the existing smart watch. The watch body 1 can realize independent timing and other functions attached to the existing smart watch. The time calibration method adopted by the existing watch body 1 is usually to record the timestamp of the moment of obtaining sensor data through the data interaction controller, or to obtain the timestamp through the PPS+GPRMC data packet method. These methods greatly increase the complexity of the running program of the watch body 1, and once there is a problem that cannot be repaired, it can only be repaired by replacing the control chip, which is extremely costly.

[0039] To address this, technicians in this field have designed an easily repairable mechanical structure, combined with the wireless communication technology of the watch body 1, to help calibrate the timing program.

[0040] According to the attached Figure 2 As shown, a reset button 2 is provided on the inner side of the watch body 1, and the timing program of the watch body 1 can be restarted by pressing the reset button 2, and the timing of the watch body 1 can be restored to a specified starting point to restart the timing program.

[0041] A carry rod 3 is provided at the rear of the watch body 1 corresponding to the reset button 2. The carry rod 3 is carried forward to contact the reset button 2, thereby realizing a physical restart of the watch body 1.

[0042] According to the attached Figure 3 and attached Figure 4 As shown, a first coil 4 is fixedly provided at one end of the carry rod 3 away from the reset button 2. The first coil 4 is electrically connected to a closed circuit of a circuit board. An independent computing chip is also installed on the circuit board, which can independently complete simple data calculation and control.

[0043] The closed circuit on the side of the circuit board is also electrically connected to a signal transceiver 5, through which a simple signal interaction with the outside world can be carried out, corresponding feedback signals can be sent and received, the timestamp in the feedback signal can be extracted, and compared and identified with the timing of the watch body 1.

[0044] The closed circuit is opened and closed based on the identified time difference. This calculation method is simple and practical, does not require complex algorithms to occupy the data of the watch body 1, and will not affect the normal use of the watch body 1.

[0045] The signal transceiver 5 receives the wireless control signal, and the chip performs on-off control of the closed circuit according to the wireless control signal. The first coil 4 generates a magnetic field under the action of the current in the closed circuit, pushing the carry rod 3 to carry, and the carry rod 3 presses the reset button 2 to reset the watch body 1, and automatically calibrates the time of the watch body 1.

[0046] A buffer pad 6 is fixed on the side of the circuit board. The buffer pad 6 is made of sponge or soft colloid as needed, which can provide buffering protection for the circuit board and the watch body 1. In addition, the current in the watch body 1 is very small, and there is no problem of coil heating and difficulty in heat dissipation.

[0047] A mounting arm 7 is fixedly connected to the side of the circuit board corresponding to the carry rod 3. The carry rod 3 is slidably arranged on the inner side of the mounting arm 7. The mounting arm 7 provides a carry space for the carry rod 3 and provides a stable support structure for the carry installation of the carry rod 3.

[0048] According to the attached Figure 5 As shown, a fixing block 8 is threadedly connected to the side surface of the carrying rod 3, and a spring 9 is sleeved and arranged on the side surface of the carrying rod 3 through the fixing block 8 to press against the side wall of the mounting arm 7.

[0049] The threaded fixing block 8 facilitates adjustment of the installation position on the side of the carry rod 3, and thus facilitates adjustment when the mounting arm 7 is deformed, thereby ensuring the installation position and carry distance of the carry rod 3 relative to the reset button 2. In addition, the spring 9 provides a reset force for the carry rod 3. After the magnetic field of the first coil 4 is lost, the elastic force of the spring 9 resets the carry rod 3, thereby preventing the reset button 2 from being damaged due to long-term pressing.

[0050] The end of the mounting arm 7 is fixedly connected to a U-shaped block 10 , the carrying rod 3 passes through the side wall of the U-shaped block 10 and is slidably connected thereto, and the fixing block 8 is arranged on the inner side of the U-shaped block 10 .

[0051] The setting of the U-shaped block 10 not only provides a basis for the stable installation of the carry rod 3, but also realizes the guiding use of the carry rod 3 through a lighter structure, and also facilitates the threaded installation and adjustment of the fixing block 8 on the side of the carry rod 3.

[0052] A battery core 11 is fixed on the side of the circuit board and inside the first coil 4. When current exists in the first coil 4 arranged outside the battery core 11, the battery core 11 arranged inside the first coil 4 is endowed with magnetic force, and the carry rod 3 is driven to carry by the magnetic force.

[0053] The carry rod 3 is installed coaxially with the battery cell 11 to ensure that the battery cell 11 exerts a stable thrust on the carry rod 3. A second coil 12 is sleeved on the outer side of the carry rod 3. The second coil 12 is also connected to the closed circuit on the circuit board. The second coil 12 and the first coil 4 are reverse windings.

[0054] After the first coil 4 and the second coil 12 of the reverse winding are energized, the carry rod 3 and the battery core 11 arranged inside thereof are given magnetic forces in opposite directions, and the repulsive force therebetween pushes the sliding carry rod 3 to carry.

[0058] S3, the chip controls the closed circuit to be turned on with a certain advance amount according to the time difference obtained by comparison;

[0059] S4. A magnetic field is generated in the first coil 4 and the second coil 12 through a closed circuit. The magnetic force drives the carry rod 3 to carry, thereby triggering the time adjustment of the watch body 1, restarting the timing program of the watch body 1 at a specific time point, and reducing the timing error.

[0063] Furthermore, a second coil 12 is arranged on the outside of the carry rod 3 in the opposite direction to the first coil 4. When power is turned on, a magnetic field in the opposite direction is generated between the battery cell 11 and the carry rod 3.
