[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only partial embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] See also Figure 1 As shown, a rechargeable and non-rechargeable dual-purpose clock movement includes a movement housing 1, a main control circuit board, a rechargeable battery 2 and a non-rechargeable battery 3. The main control circuit board integrates an MCU 4, a charging circuit, a discharging circuit, and a clock circuit; the rechargeable battery 2 and the non-rechargeable battery 3 are installed in the movement housing. On this basis, the dual-purpose clock movement also includes a battery power monitoring circuit 5 and a switching circuit 6.

[0025] The battery power monitoring circuit 5 is electrically connected to the non-rechargeable battery, and is used to monitor the power of the non-rechargeable battery, and output a signal when the power does not reach a preset threshold. There are many ways to implement the battery power monitoring circuit, and there are even many battery power monitoring circuit chips at present. For example, the chip model CN3063, this chip has a low cost and can be used to measure the voltage, current or power of a single or multiple batteries. The circuit for accurately measuring the battery power can also be designed using the existing high-side current sensor model FAN4010. Therefore, there are already a variety of circuits that can be implemented or integrated chips in the prior art. Those skilled in the art can easily implement a variety of specific circuits based on the fact that the circuit functions have been fully disclosed and combined with common knowledge or prior art. Therefore, the utility model does not place a specific circuit diagram of the battery power monitoring circuit.

[0026] The preset threshold value can be set according to actual needs. For example, when the power does not reach 5% of the preset rated total power, a signal is output.

[0027] The switching circuit 6 has two input terminals 61 and 62, which are electrically connected to the rechargeable battery 2 and the non-rechargeable battery 3 respectively, and are controlled by the signal of the battery power monitoring circuit 5 to select one of the rechargeable battery and the non-rechargeable battery as the load power supply, and the load power supply is the power supply required for the clock movement; when the non-rechargeable battery reaches a preset threshold, the switching circuit selects the non-rechargeable battery as the load power supply, and when the non-rechargeable battery does not reach the preset threshold, the switching circuit selects the rechargeable battery as the load power supply according to the received input signal. Similarly, there are already a variety of power switching circuits that can be implemented in the prior art. Those skilled in the art can easily implement a variety of specific circuits based on the fact that the circuit functions have been fully disclosed and combined with common knowledge or prior art. Therefore, the utility model does not place a specific circuit diagram of the switching circuit.

[0028] As a specific implementation, the battery power monitoring circuit and the switching circuit are integrated on the main control circuit board and electrically connected to the MCU on the main control circuit board. In this way, only one main control circuit board is needed to integrate multiple required circuits.

[0029] As a specific implementation, a memory (not shown) is integrated on the main control circuit board for storing a preset threshold value. In this way, it can be used to store a preset control value, and the MCU can be controlled according to the preset threshold value.

[0030] As a specific implementation, the MCU 4 is connected to a power on / off button 9. In this way, the entire movement can be turned off, and the consumption of the non-rechargeable battery power can be reduced before use.

[0031] When the non-rechargeable battery reaches a preset threshold, the switching circuit selects the non-rechargeable battery as the load power supply; when the non-rechargeable battery does not reach the preset threshold, the switching circuit selects the rechargeable battery as the load power supply according to the received input signal, thereby achieving the dual-use of non-rechargeable batteries and rechargeable batteries, extending the battery life, and extending the time for battery replacement. When the non-rechargeable battery is low on power and cannot work, it automatically switches to the rechargeable battery, and the non-rechargeable battery can be updated within a longer time range. When the non-rechargeable battery is replaced with a new battery, it can be further automatically switched back to the original non-rechargeable battery for power supply through the switching circuit.

[0032] Example 2

[0033] Referring to Example 1, on the basis of Example 1, the MCU 4 is connected to a charging interface 7, and the charging interface 7 extends to the movement housing 1. In this way, the rechargeable battery can be powered in real time, and the battery life can be continued when the non-rechargeable battery is not replaced.

[0034] Example 3

[0035] Referring to Example 1, on the basis of Example 1, a manual toggle switch 8 is provided between the rechargeable battery 2 and the non-rechargeable battery 3, and one of the rechargeable battery 2 and the non-rechargeable battery 3 is directly selected as the load power supply through the manual toggle switch 8. In this way, there is a manual toggle switch, and when necessary, the toggle switch can be toggled to switch to the rechargeable battery or the non-rechargeable battery, which increases the user's selectivity and flexibility.

[0036] When the manual toggle switch is not working, that is, when it is not toggled, the manual toggle switch does not play any role, and it still works in the manner of Example 1. When working, on the one hand, the manual switch can be toggled to the non-rechargeable battery, at which time the path of the non-rechargeable battery is connected and the path of the rechargeable battery is cut off. At this time, it is equivalent to only using the non-rechargeable battery for power supply. On the other hand, the manual switch can also be toggled to the rechargeable battery, at which time the path of the rechargeable battery is connected and the path of the non-rechargeable battery is cut off. At this time, it is equivalent to only using the rechargeable battery for power supply. In this way, compared with Example 1, two working modes are added, which increases selectivity and flexibility.

[0037] See also Figure 4 As shown, the manual toggle switch can be designed into 1st gear, 2nd gear and 3rd gear. 1st gear is on the left, 2nd gear is in the middle, and 3rd gear is on the right. When not toggled, it is in the middle 2nd gear. You can toggle to the left 1st gear, or to the right 3rd gear. In this way, there are three options: 1st gear, 2nd gear or 3rd gear. No matter which gear position it is in, you can toggle to select another gear you need.

[0038] When the toggle switch is in the second position, both the rechargeable battery and the non-rechargeable battery are disconnected; when the toggle switch is in the first position, only the non-rechargeable battery is connected; when the toggle switch is in the third position, only the rechargeable battery is connected.

[0039] In the present utility model, the charging circuit, the discharging circuit, and the clock circuit are circuits already existing in the prior art. The prior art mentioned in the background technology also involves the charging circuit, the discharging circuit, and the clock circuit, and the charging circuit, the discharging circuit, and the clock circuit are not improvements of the present application. Furthermore, those skilled in the art can easily realize a variety of specific circuits based on the fact that the functions of the circuits have been fully disclosed and combined with common knowledge or prior art. Therefore, the present utility model does not place specific circuit diagrams of the charging circuit, the discharging circuit, and the clock circuit.

[0040] The series of detailed descriptions listed above are only specific descriptions of feasible embodiments of the present invention. They are not intended to limit the protection scope of the present invention. All equivalent embodiments or changes that do not deviate from the technical spirit of the present invention should be included in the protection scope of the present invention.
