An electrode spring passes through the lower part of the inner watch body and abuts against the negative terminal of a button cell battery. The button cell battery supplies power to the quartz movement and the circuit board.

[0007] Furthermore, the outer shell includes an upper shell and a lower shell. The upper shell has several snap-fit ​​parts on its side, and the lower shell has several protrusions on its side. The snap-fit ​​parts cooperate with the protrusions to fix the upper shell and the lower shell together.

[0028] Example 1

[0029] Please see Figures 1 to 5 This utility model provides a technical solution:

[0030] An integrated power supply structure for a dual-movement electronic watch includes an inner watch body 9, which is located inside a casing. The inner watch body 9 contains a quartz movement 13 and a circuit board 11. The quartz movement 13 is positioned below the circuit board 11, and its output terminal passes through the circuit board 11 to drive a pointer 3 to rotate. An electrode spring 14 passes through the lower part of the inner watch body 9 and abuts against the negative terminal of a button cell battery 8. The button cell battery 8 supplies power to the quartz movement 13 and the circuit board 11.

[0031] Specifically, such as Figure 1 and Figure 3 As shown, the outer shell includes an upper shell 1 and a lower shell 7. The upper shell 1 has a plurality of snap-fit ​​parts 101 on its side, and the lower shell 7 has a plurality of protrusions 701 on its side. The snap-fit ​​parts 101 cooperate with the protrusions 701 to fix the upper shell 1 and the lower shell 7 together.

[0032] Specifically, the upper shell 1 and the lower shell 7 are preferably made of plastic.

[0033] With the above structure, when the upper shell 1 and the lower shell 7 are installed, due to the elasticity of the plastic itself, the buckle 101 and the protrusion 701 are squeezed and elastically deformed. Then the protrusion 701 enters the groove of the buckle 101 to achieve a tight connection. When disassembling, the buckle 101 is pried outward to make the protrusion 701 leave the buckle 101 and it can be easily disassembled.

[0034] Specifically, such as Figure 2 As shown, the lower shell 7 is provided with a battery compartment 702. A battery fixing buckle 704 is provided on one side of the battery compartment 702, and a battery baffle 703 is provided on the other side. An electrode is provided on the inner side of the battery baffle 703, and the inner side of the battery baffle 703 abuts against the positive electrode of the button battery 8.

[0035] Specifically, the battery retaining clip 704 is made of elastic plastic. When it is necessary to install or remove the battery, the battery retaining clip 704 is moved to separate it from the contact with the button battery 8. Then, the battery retaining clip 704 returns to its original position due to its elasticity, thereby fixing the button battery 8.

[0036] With the above structure, the button battery 8 can be replaced without disassembling the outer casing, avoiding damage to the quartz movement 13 and / or circuit board 11 during disassembly and assembly, making it more convenient to use.

[0037] Specifically, such as Figure 4 As shown, the inner watch body 9 includes a dial fixing plate 901, a movement fixing box 902, a circuit board fixing seat 903, and a quartz movement fixing plate 904. The dial 2 is fixedly mounted on the upper end of the dial fixing plate 901, and the lower end is fixedly connected to the movement fixing box 902. The circuit board fixing seat 903 is fixedly mounted on both ends of the quartz movement 13 fixing seat and is perpendicular to the quartz movement fixing plate 904. The quartz movement 13 is fixedly mounted at the center of the quartz movement fixing plate 904, and both ends of the circuit board 11 are fixedly mounted on the circuit board fixing seat 903.

[0038] Specifically, the output end of the quartz movement 13 is a stepper motor.

[0039] Specifically, such as Figure 4 As shown, the quartz movement 13 has a time-setting lever 5 on its side, and the operating end of the time-setting lever 5 extends outward through the inner watch body 9 and the outer casing.

[0040] Specifically, such as Figure 4 As shown, a plurality of controllers 12 are provided between the quartz movement fixing plate 904 and the circuit board 11. The controller 12 has two pins at its tail end, the lower pin is fixedly connected to the quartz movement fixing plate 904, and the upper pin is electrically connected to the upper end of the circuit board 11. A plurality of buttons 6 are provided on the side of the upper shell 1. The buttons 6 correspond to the controllers 12. The buttons 6 move inward to trigger the controllers 12.

[0041] Specifically, such as Figure 1 and 4 As shown, the output end of the quartz movement 13 is fixedly provided with a rotating shaft 4, which is located at the center of the dial 2. A pointer 3 is sleeved on the rotating shaft 4 and is located above the dial 2. A display screen 10 is provided on the circuit board 11, and the upper end of the display screen 10 is located inside the dial 2 and is flush with the upper surface of the dial 2.

[0042] Specifically, such as Figure 5As shown, the button battery 8 supplies power to the circuit board 11 via a rectifier bridge and to the quartz movement 13 via a boost module. The power supply lines of the circuit board 11 and the quartz movement 13 are independent of each other.

[0043] With the above structure, since the circuit board 11 and the quartz movement 13 are independent of each other, and the power consumption and rated voltage of the quartz movement 13 are both lower than those of the circuit board 11, the boost module provides a stable voltage to the quartz movement 13, avoiding changes in the stepper motor speed when the voltage of the button battery 8 changes, which would lead to inaccurate time indication. When the voltage of the button battery 8 is insufficient to support the circuit board 11 to continue working, it does not affect the normal operation of the quartz movement 13.

[0044] In this embodiment, when using the device, the technician first moves the battery retaining clip 704 to install the button battery 8, inserting the positive terminal of the button battery 8 into the battery baffle 703. The negative terminal of the button battery 8 abuts against the electrode spring 14 and compresses the electrode spring 14. Due to the elasticity of the electrode spring 14, the positive terminal of the button battery 8 can be tightly attached to the electrode in the battery baffle 703, avoiding poor contact. Then, the technician rotates the time adjustment lever 5 to adjust the time of the pointer 3, and presses the button 6 to trigger the controller 12 to adjust the digital time and calendar on the display screen 10.

[0045] Example 2

[0046] Please see Figure 6 This utility model also provides a technical solution that is basically the same as that in Embodiment 1. The same parts will not be described again. The main difference is that:

[0047] Specifically, such as Figure 6 As shown, the button cell battery 8 supplies power to the circuit board 11 via a rectifier bridge, and then supplies power to the quartz movement 13 via the boost module. The quartz movement 13 is connected in parallel with the circuit board 11 through a diode and a resistor led out from the button cell battery 8.

[0048] In this embodiment, since the main circuit of the quartz movement 13 is located after the power supply circuit of the circuit board 11, the power supply structure of this embodiment has a higher degree of integration, further reducing the volume occupied by the power supply structure. The total resistance of the diodes and resistors led out from the button battery 8 is greater than or equal to the total resistance of the circuit board 11. Therefore, the diodes can continue to supply power to the circuit of the quartz movement 13 when a short circuit occurs in the circuit of the circuit board 11, avoiding the normal operation of the quartz movement 13 when the circuit of the circuit board 11 fails.

[0049] The parts of this utility model not described are existing or known technologies.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
