[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] Embodiment 1

[0033] refer to Figure 1 and Figure 2 , this embodiment 1 provides a battery identification device, including:

[0034] Wireless receiving components, including:

[0035] A battery compartment 20 and a controller electrically connected to the battery compartment 20;

[0036] The controller includes a circuit board 10 and a control circuit disposed on the circuit board 10;

[0037] One end of the battery compartment 20 is provided with a conductive sheet 21 detachably connected to the battery compartment 20;

[0038] The other end of the battery compartment 20 is provided with an elastic component 30, and the elastic component 30 is electrically connected to the circuit board 10;

[0039] The elastic component 30 includes a first elastic member 31 and a second elastic member 32 disposed inside the first elastic member 31 . The length of the first elastic member 31 is greater than that of the second elastic member 32 .

[0040] A signal point 11 is provided on the circuit board 10 at a position corresponding to the second elastic member 32;

[0041] The controller identifies the type of the battery according to the output level of the signal point 11 when the battery 1 is placed in the battery compartment 20 .

[0042] In this embodiment, the battery compartment 20 is used to place dry cell batteries or lithium batteries, wherein the length of the dry cell battery pack is shorter than the length of the lithium battery pack.

[0043] When the battery 1 is placed in the battery compartment 20, the two ends of the battery 1 are respectively in contact with the conductive sheet 21 and the first elastic member 31, so that a loop is formed between the battery 1 and the controller. When the battery 1 is a small-sized dry cell, the second elastic member 32 has no contact with the battery 1, the signal point 11 is disconnected from the battery 1, and the signal point 11 outputs a low level. When the battery 1 is a large-sized lithium battery, the second elastic member 32 is in contact with the battery 1, the signal point 11 is electrically connected to the battery 1, and the signal point 11 outputs a high level. The controller identifies the battery according to the output level of the signal point.

[0044] In this embodiment, the conductive sheet 21 is a negative electrode connecting sheet connected to the negative electrode of the battery 1. The first elastic member 31 is connected to the positive electrode of the battery 1. When the battery 1 is inserted, the positive and negative electrodes of the battery 1 are connected to the first elastic member 31 and the conductive sheet 21 respectively, so as to form a loop between the battery 1 and the controller.

[0045] Specifically, in the natural state, the length of the first elastic member 31 is greater than the length of the second elastic member 32. When the battery 1 is placed, the first elastic member 31 first deforms and contacts the battery 1. When the battery 1 is a lithium battery with a larger size, the second elastic member 32 deforms and contacts the battery 1. At this time, the signal point 11 is electrically connected to the battery 1, and the signal point 11 outputs a high level. When a dry cell battery is placed, the second elastic member 32 does not deform and contacts the battery 1 because the dry cell battery is smaller in size. At this time, the signal point 11 is disconnected from the battery 1 and outputs a low level.

[0046] In this embodiment, the elastic component 30 is connected to the positive electrode of the battery 1. When the signal point 11 outputs a high level, the controller determines that the battery 1 is a lithium battery; when the signal point 11 outputs a low level, the controller determines that the battery 1 is a dry cell.

[0047] In another embodiment, the elastic component 30 is connected to the negative electrode of the battery 1. Specifically, the conductive sheet 21 is a positive electrode connecting sheet connected to the positive electrode of the battery 1. The first elastic member 31 is connected to the negative electrode of the battery 1. When the battery 1 is inserted, the positive and negative electrodes of the battery 1 are connected to the conductive sheet 21 and the first elastic member 31 respectively, so as to form a loop between the battery 1 and the controller.

[0048] When the battery 1 is a small-sized dry cell, the second elastic member 32 does not deform and does not contact the negative electrode of the battery 1. At this time, the signal point 11 is disconnected from the battery 1 and outputs a high level. When the battery 1 is a large-sized lithium battery, the second elastic member 32 deforms and contacts the battery 1. At this time, the signal point 11 is electrically connected to the negative electrode of the battery 1, and the original level of the signal point 11 is pulled down, which is called a low level. Therefore, the controller can determine the model of the battery 1 according to the output level of the signal point 11.

[0049] Specifically, the elastic component 30 is connected to the negative electrode of the battery 1. When the signal point 11 outputs a high level, the controller determines that the battery 1 is a dry cell battery; when the signal point 11 outputs a low level, the controller determines that the battery 1 is a lithium cell battery.

[0050] In this embodiment, the battery 1 may also be a battery of other sizes. Depending on the control circuit, when the signal point 11 is electrically connected or disconnected from the battery, the level of the signal point 11 changes, and the controller can identify the battery model according to the change in the output level of the signal point 11.

[0051] In this embodiment, the first elastic member 31 and the second elastic member 32 may be springs, elastic sheets, or reed leaves, etc., whichever can play an elastic supporting role.

[0052] In this embodiment, when the battery 1 is placed, the two ends of the battery 1 respectively abut against the conductive sheet 21 and the first elastic member 31, so that a loop is formed between the battery 1 and the controller; when the first elastic member 31 is connected to the positive electrode of the battery 1, if the signal point 11 generates a high level, the battery 1 is a lithium battery, and if the signal point 11 generates a low level, the battery 1 is a dry cell. When the first elastic member 31 is connected to the negative electrode of the battery 1, if the signal point 11 generates a high level, the battery 1 is a dry cell, and if the signal point 11 generates a low level, the battery 1 is a lithium battery. The battery identification device can identify the battery model only according to the output level of the signal point 11, is simple and easy to implement, does not require complex circuits and judgment procedures, and has low cost.

[0053] Embodiment 2

[0054] refer to Figure 1 and Figure 4 On the basis of the first embodiment, the second elastic member 32 of the second embodiment is electrically connected to the signal point 11 .

[0055] In this embodiment, the first elastic member 31 and the second elastic member 32 are independently provided, and both the first elastic member 31 and the second elastic member 32 are welded on the circuit board 10. In the natural state, the second elastic member 32 is electrically connected to the signal point 11.

[0056] When the battery 1 is inserted, if the second elastic member 32 contacts the battery 1, the signal point 11 is electrically connected to the battery 1 through the second elastic member 32. If the second elastic member 32 does not contact the battery 1, the signal point 11 is disconnected from the battery 1. The controller identifies the type of the battery 1 according to the output level of the signal point 11.

[0057] Embodiment 3

[0058] refer to Figure 1 and Figure 4 On the basis of the second embodiment, the first elastic member 31 of the third embodiment is spiral-shaped, and the outer diameter of the first elastic member 31 gradually decreases from the bottom end to the top end.

[0059] In this embodiment, the first elastic member 31 is spiral-shaped, and the outer diameter gradually decreases from the bottom to the top. The second elastic member 32 is spiral-shaped, and the outer diameter is the same from the bottom to the top, which prevents the first elastic member 31 from contacting the second elastic member 32 when pressed, avoids misjudgment of the signal point 11, and improves the recognition accuracy.

[0060] In other embodiments, the first elastic member 31 and the second elastic member 32 are both straight springs, and the outer diameters are the same from the bottom to the top. When the first elastic member 31 undergoes elastic deformation, it does not affect the second elastic member 32 .

[0061] Furthermore, central axes of the first elastic member 31 and the second elastic member 32 are on the same line.

[0062] In this embodiment, the central axes of the first elastic member 31 and the second elastic member 32 are on the same line to ensure that the first elastic member 31 and the second elastic member 32 are in contact with the positive or negative electrode of the battery 1 when pressed, so as to form a loop between the battery 1 and the controller.

[0063] Embodiment 4

[0064] refer to Figure 3 On the basis of the first or third embodiment, the first elastic member 31 and the second elastic member 32 of the fourth embodiment are integrally formed, and the second elastic member 32 is formed by bending the top end of the first elastic member 31 in the opposite direction.

[0065] In this embodiment, the first elastic member 31 is disposed on the circuit board 10 , and the second elastic member 32 is disposed at an end of the first elastic member 31 away from the circuit board 10 , and has no contact with the circuit board 10 in a natural state.

[0066] The outer diameter of the first elastic member 31 decreases gradually from the bottom to the top in a spiral shape, and the outer diameter of the second elastic member 32 is the same from top to bottom. The central axis of the second elastic member 32 corresponds to the signal point 11. The first elastic member 31 is prevented from contacting the second elastic member 32 when pressed, avoiding misjudgment of the signal point 11 and improving the recognition accuracy.

[0067] In another embodiment, the first elastic member 31 and the second elastic member 32 are both straight springs, so as to prevent the first elastic member 31 from affecting the second elastic member 32 when elastic deformation occurs.

[0068] When a dry cell battery is placed in the battery compartment 20, the center of the second elastic member 32 is suspended in the air and has no contact with the signal point 11. At this time, the signal point 11 is disconnected from the battery 1. When a larger lithium battery is placed, the second elastic member 32 contacts the signal point 11. At this time, the signal point 11 is electrically connected to the battery 1.

[0069] In the battery identification device of this embodiment, the first elastic member 31 and the second elastic member 32 are integrally formed, thereby simplifying the installation procedure and improving the stability of the identification device.

[0070] Embodiment 5

[0071] refer to Figure 3 , this embodiment 5 provides an electrical device, including a housing, the above-mentioned battery identification device, and an electrical device connected to a controller. The electrical device may be a lighting device or a smart home device. In this embodiment, a flashlight is used as an example for explanation:

[0072] The flashlight comprises a body 2, an illuminating lamp 3 and the battery identification device mentioned above. The flashlight can automatically identify the battery model according to the output level of the signal point 11, thereby providing the illuminating lamp 3 with different output powers.

[0073] Furthermore, the conductive sheet is connected to the controller through the housing.

[0074] In this embodiment, the shell is the barrel 2 of the flashlight, and the conductive sheet 21 is connected to the negative circuit of the controller through the barrel 2. When the rear cover of the flashlight is not installed, the flashlight cannot be turned on. This can prevent the signal point 11 from generating an erroneous output level when the deformation amount is large due to external pressure, thereby causing misjudgment.

[0075] Furthermore, the controller controls the electrical equipment to output a preset power according to the output level of the signal point 11 .

[0076] In this embodiment, the elastic component 30 is connected to the positive electrode of the battery 1. When the signal point 11 outputs a high level, the battery 1 is determined to be a lithium battery, and the flashlight is controlled to output a larger power or current. When the signal point 11 outputs a low level, the battery 1 is determined to be a dry cell battery, and the flashlight is controlled to output a smaller power or current.

[0077] In another embodiment, the elastic component 30 is connected to the negative pole of the battery 1. When the signal point 11 outputs a high level, it is determined that the battery 1 is a dry cell, and the flashlight is controlled to output a smaller power or current. When the signal point 11 outputs a low level, it is determined that the installed battery 1 is a lithium battery, and the flashlight is controlled to output a larger power or current. It should be noted that the battery identification device only makes a judgment when it is turned on or powered on again, and does not make a judgment during the power use process, so as to avoid the output level of the signal point 11 changing due to the flashlight falling, thereby causing a misjudgment.

[0078] In this embodiment, the flashlight is connected to the negative circuit of the conductive sheet 21 through the body to avoid misjudgment caused by large size change due to strong pressure when inserting the battery 1. In addition, the battery 1 is only identified when the flashlight is turned on or powered on again to avoid misjudgment caused by changes in the level of the signal point 11 due to falling during power use.

[0079] The electrical device of this embodiment identifies the battery through the output level of the signal point 11 when it is powered on or turned on, so that the electrical device outputs different powers and performs differentiated output, thereby improving the efficiency of the electrical device.

[0080] The present invention provides a battery identification device, which is provided with a controller and a battery compartment 20, wherein the elastic component includes a first elastic member 31 and a second elastic member 32 arranged inside the first elastic member 31, the length of the first elastic member 31 is greater than the length of the second elastic member 32, and a signal point 11 is provided at a position corresponding to the second elastic member 32 on the circuit board 10, and the controller identifies the battery according to the output level of the signal point 11 when the battery 1 is placed in the battery compartment 20. When the battery 1 is placed, the two ends of the battery 1 respectively abut against the conductive sheet 21 and the first elastic member 31, so that a loop is formed between the battery 1 and the controller; when the first elastic member 31 is connected to the positive electrode of the battery 1, if the signal point 11 generates a high level, the battery 1 is a lithium battery, and if the signal point 11 generates a low level, the battery 1 is a dry cell. When the first elastic member 31 is connected to the negative electrode of the battery 1, if the signal point 11 generates a high level, the battery 1 is a dry cell, and if the signal point 11 generates a low level, the battery 1 is a lithium battery. The battery identification device can identify the battery model only according to the output level of the signal point 11, is simple and easy to implement, does not require complex circuits and judgment procedures, and has low cost. By making the first elastic member 31 spiral, and the outer diameter gradually decreases from the bottom to the top; the second elastic member 32 spiral, and the outer diameter bottom and top are the same, the first elastic member 31 is prevented from contacting the second elastic member 32 when slightly pressed, thereby improving the recognition accuracy. In addition, by forming the first elastic member 31 and the second elastic member 32 in one piece, the installation procedure is simplified, and the stability performance is good.

[0081] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
