DETAILED DESCRIPTION

[0045] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0046] In the specification, unless otherwise clearly stated, the terms "first" and "second" are used only to describe and distinguish constituent elements, and should not be understood as indicating an order. Unless otherwise clearly stated, the terms "connected", "fixed", etc. should be understood as having a broad meaning, including but not limited to directly, indirectly, detachably "connected", "fixed", etc.

[0047] The present disclosure provides a battery protection device, such as Figure 1 , Figure 4 As shown, the battery protection device includes: a battery 10, a battery protection board 20, an alarm module 30, a conductive elastic member 40 and a temperature sensing connector 50.

[0048] The battery protection board 20 is an integrated circuit board composed of various electronic devices and circuits, which is electrically connected to the positive and negative electrodes of the battery 10 respectively, and controls the charging and discharging processes of the battery 10 to protect the battery.

[0049] The alarm module 30 is used to perform a battery protection function, which may include at least one of the following:

[0050] Send out an alarm signal;

[0051] Control charging current;

[0052] Control charging voltage;

[0053] Control the discharge current;

[0054] Control the discharge voltage;

[0055] Stop charging and discharging.

[0056] In some embodiments, the alarm module can determine the corresponding battery protection function based on the type of battery, the maximum temperature that the battery can withstand, the working efficiency of the battery at different temperatures, etc. The functional devices or modules included in the alarm module 30 will also be different depending on the battery protection function.

[0057] For example, when the alarm module 30 includes a buzzer, the buzzing sound emitted by the alarm module 30 can be used as an alarm signal.

[0058] For example, when the alarm module 30 includes a vibration module, the vibration generated by the alarm module 30 can be used as an alarm signal.

[0059] For example, when the alarm module 30 includes a voice module, the voice emitted by the alarm module 30 can be used as an alarm signal.

[0060] The conductive elastic member 40 is fixed to the battery protection board 20 , or fixed to the alarm module 30 .

[0061] The temperature sensing connector 50 is fixed on the surface of the battery 10, and the limiting portion 51 included therein is connected to the conductive elastic member 40 to provide external force to the conductive elastic member 40. When the temperature of the battery 10 does not cause the temperature sensing connector 50 to deform, the external force provided by the limiting portion 51 makes it impossible for the conductive elastic member 40 to be electrically connected to the battery protection board 20 and the alarm module 30, and thus it is impossible to form an electrical path between the alarm module 30 and the battery protection board 20, that is, the alarm module 30 is not triggered to perform the battery protection function.

[0062] When the temperature of the battery 10 causes the temperature sensing connector 50 to deform, the external force provided by the limiter 51 is released, so that the conductive elastic member 40 is electrically connected to the battery protection board 20 and the alarm module 30 under the elastic force, thereby forming an electrical path from the alarm module 30 to the battery protection board 20, triggering the alarm module 30 to perform the battery protection function. The temperature of the battery 10 causing the temperature sensing connector 50 to deform may include: the temperature sensing connector 50 is melted, the temperature sensing connector 50 is extended, the temperature sensing connector 50 is expanded, and the temperature sensing connector 50 is contracted.

[0063] That is to say, the conductive elastic member 40 is a connecting bridge between the battery protection board 20 and the alarm module 30 , and the external force provided by the limiting portion 51 is used to limit the conductive elastic member 40 to form an electrical path between the alarm module 30 and the battery protection board 20 .

[0064] In some embodiments, Figure 1 , Figure 2 , Figure 3 As shown, the conductive elastic member 40 can be directly electrically connected to the battery protection board 20, but not connected to the alarm module 30; or, the conductive elastic member 40 can be indirectly electrically connected to the battery protection board 20, but not connected to the alarm module 30. When the temperature of the battery 10 causes the temperature-sensing connector 50 to deform, the external force provided by the limiter 51 is released, so that the conductive elastic member 40 is electrically connected to the alarm module 30 under the action of the elastic force. At this time, the conductive elastic member 40 is also electrically connected to the battery protection board 20, forming an electrical path between the alarm module 30 and the battery protection board 20.

[0065] In other embodiments, Figure 4 , Figure 6 As shown, the conductive elastic member 40 can be directly electrically connected to the alarm module 30, but not connected to the battery protection board 20; or, the conductive elastic member 40 can be indirectly electrically connected to the alarm module 30, but not connected to the battery protection board 20. When the temperature of the battery 10 causes the temperature-sensing connector 50 to deform, the external force provided by the limiter 51 is released, so that the conductive elastic member 40 is electrically connected to the battery protection board 20 under the action of the elastic force. At this time, the conductive elastic member 40 is also electrically connected to the alarm module 30, forming an electrical path between the alarm module 30 and the battery protection board 20.

[0066] In some embodiments, Figure 2 As shown, the first end of the temperature sensing connector 50 is fixed to the surface of the battery 10; the limiting portion 51 includes: a limiting hole 52 formed at the second end of the temperature sensing connector 50; the first end of the conductive elastic member 40 is electrically connected to the battery protection plate 20, and the second end of the conductive elastic member 40 passes through the limiting hole 50.

[0067] In this embodiment, the first end of the temperature sensing connector 50 is attached to the surface of the battery 10 by bonding (such as dispensing or adhesive) to sense the surface temperature of the battery 10. The first end of the conductive elastic member 40 is electrically connected to the battery protection board 20 by welding, and the second end of the conductive elastic member 40 passes through the limiting hole 52 at the second end of the temperature sensing connector 50. The limiting hole 52 provides a pulling force for the conductive elastic member 40 to move away from the alarm module 30, thereby limiting the position of the conductive elastic member 40 between the battery protection board 20 and the alarm module 30.

[0068] like Figure 2As shown, when the limiting hole 52 provides a pulling force for the conductive elastic member 40 to move away from the alarm module 30, the conductive elastic member 40 is deformed and convex due to the pulling force, and a first contact point 60 is provided at the deformed convex portion of the conductive elastic member 40. When the temperature of the battery rises and causes the temperature sensing connecting member 50 to deform, the pulling force provided by the limiting hole 52 on the temperature sensing connecting member 50 is released, and the first contact point 60 located at the deformed convex portion of the conductive elastic member 40 rebounds due to the loss of the pulling force, so that the first contact point 60 is electrically connected to the alarm module 30.

[0069] In some embodiments, Figure 3 As shown, the limiting portion 51 of the temperature sensing connector 50 may further include a limiting groove, in which the conductive elastic member 40 may be fixed, and the limiting groove provides a pulling force for the conductive elastic member 40 to move away from the alarm module 30 to limit the position of the conductive elastic member 40 .

[0070] That is to say, the limiting portion 51 of the temperature sensing connector 50 can be a limiting structure in various forms, such as a limiting hole, a limiting groove, a limiting hook, etc. Exemplarily, the second end of the temperature sensing connector 50 is a limiting hook, which can fix the position of the entire conductive elastic member 40 by hooking the second end of the conductive elastic member 40.

[0071] In addition, in order to facilitate the electrical connection between the first contact point 60 and the alarm module 30 under the action of elastic force, a protrusion is also provided on the alarm module 30 at a position relative to the first contact point 60. The first contact point 60 forms an electrical connection with the alarm module 30 by contacting the protrusion.

[0072] In some embodiments, the material of the temperature sensing connector 50 can be a heat-melting material. Since the first end of the temperature sensing connector 50 is attached to the surface of the battery 10, the second end including the limiting hole provides a pulling force for the conductive elastic member to move away from the alarm module 30.

[0073] Therefore, when the temperature of the battery 10 rises and reaches the melting point of the temperature-sensing connector 50, one situation is: the first end of the temperature-sensing connector 50 is disconnected due to heat, and the pulling force on the conductive elastic member 40 is released, so that the first contact point 60 of the conductive elastic member 40 is electrically connected to the alarm module 30; another situation is: the first end of the temperature-sensing connector 50 melts, the pulling force is weakened, and under the elastic force of the conductive elastic member 40, the temperature-sensing connector 50 is extended toward the alarm module 30, so that the first contact point 60 of the conductive elastic member 40 is electrically connected to the alarm module 30.

[0074] In some embodiments, Figure 4 , Figure 5 , Figure 6As shown, the first end of the temperature sensing connector 50 is fixed to the surface of the battery 10; the limiting portion 51 includes: a limiting protrusion 53 formed at the second end of the temperature sensing connector 50; the first end of the conductive elastic member 40 is electrically connected to the alarm module 30, and the first part of the second end of the conductive elastic member 40 abuts against the limiting protrusion 53.

[0075] In this embodiment, the first end of the temperature sensing connector 50 is attached to the surface of the battery 10 by bonding (such as dispensing or adhesive backing) to sense the surface temperature of the battery 10. The first end of the conductive elastic member 40 is electrically connected to the alarm module 00 by welding, and the first part of the second end of the conductive elastic member 40 abuts against the limiting protrusion 53 of the second end of the temperature sensing connector 50. Under the abutting force of the limiting protrusion 53, the conductive elastic member 40 is away from the battery protection board 20, thereby limiting the position of the conductive elastic member 40 between the alarm module 30 and the battery protection board 20, so that no electrical path can be formed between the alarm module 30 and the battery protection board 20.

[0076] In this embodiment, the second end of the conductive elastic member 40 includes two parts, the first part abuts against the limiting protrusion 53 of the temperature sensing connector 50 , and the second part does not contact the limiting protrusion 53 of the temperature sensing connector 50 .

[0077] In addition, since the battery protection board 20 is electrically connected to the battery 10 and the temperature sensing connector 50 is fixed to the surface of the battery 10 , the temperature sensing connector 50 may or may not be in contact with the surface of the battery protection board 20 .

[0078] In some embodiments, the first portion of the second end of the conductive elastic member 40 is a protrusion formed by extending the conductive elastic member 40. The protrusion allows the temperature sensing connector 50 to abut against the conductive elastic member 40 more closely, so that the limiting protrusion 53 of the temperature sensing connector 50 can more stably limit or fix the position of the conductive elastic member 40.

[0079] In some embodiments, Figure 5 , Figure 6 As shown, the battery protection device also includes: a second contact point 70, wherein the second contact point 70 is located on the battery protection plate 20 and is opposite to the second part of the second end of the conductive elastic member 40; when the temperature of the battery rises and causes the temperature-sensing connecting member 50 to deform, the external force generated by the abutment between the limiting protrusion 53 and the first part of the second end of the conductive elastic member 40 is released, and the first part of the conductive elastic member 40 moves under the action of the elastic force to be electrically connected to the second contact point 70.

[0080] In this embodiment, the first part of the second end of the conductive elastic member 40 is arranged opposite to the limiting protrusion 53 of the temperature sensing connecting member 50, and the second part of the second end of the conductive elastic member 40 is arranged opposite to the second contact point 70 located on the battery protection plate 20, that is, the limiting protrusion 53 of the temperature sensing connecting member 50 is arranged adjacent to the second contact point 70.

[0081] Then, when the temperature rise of the battery 10 causes the temperature sensing connector 50 to deform, the external force generated by the contact between the limiting protrusion 53 and the first part of the second end of the conductive elastic member 40 is contacted or weakened, and the first part of the second end of the conductive elastic member 40 moves to the second contact point 70 disposed adjacent to the limiting protrusion 53 under the action of the elastic force to be electrically connected, so that the conductive elastic member 40 is electrically connected to the battery protection board 20 where the second contact point 70 is located, thereby forming an electrical path between the battery protection board 20 and the alarm module 30. In addition, in order to facilitate the electrical connection between the conductive elastic member 40 and the second contact point 70, the second contact point 70 can be a raised contact point.

[0082] In some embodiments, in order to facilitate the conductive elastic member 40 to move to the second contact point 70, the limiting protrusion 53 of the temperature sensing connector 50 may be an equilateral triangle, an inverted triangle, a triangle with an arc, or other shapes. Figure 4 , Figure 5 , Figure 6 The limiting protrusion 53 in the figure is only an exemplary embodiment and does not constitute a limitation to the present disclosure.

[0083] In some embodiments, the material of the temperature sensing connector 50 may be a material that expands when heated or a material that contracts when heated.

[0084] For example, when the temperature of the battery 10 rises to a preset temperature range (the preset temperature range is the temperature range corresponding to the deformation of the temperature sensing connector), the temperature sensing connector 50 expands, and the limiting protrusion 53 of the temperature sensing connector 50 squeezes the first part of the second end of the conductive elastic member 40 under the action of the expansion, so that the first part of the second end of the conductive elastic member 40 moves toward the direction of the second contact point 70.

[0085] For another example, when the temperature of the battery 10 rises to a preset temperature range (the preset temperature range is the temperature range corresponding to the deformation of the temperature sensing connector), the temperature sensing connector 50 contracts, so that the limiting protrusion 53 of the temperature sensing connector 50 does not abut against the conductive elastic component 40, so that the first part of the second end of the conductive elastic component 40 moves toward the second contact point 70 under the action of the elastic force.

[0086] In some embodiments, the alarm module 30 is configured to send out an alarm signal when electrically connected to the battery protection board 20; and / or to adjust the charging and discharging of the battery through the battery protection board 20.

[0087] In this embodiment, the alarm module 30 is used to perform a battery protection function, and the battery protection function may include: issuing an alarm signal, controlling the charging current or charging voltage, controlling the discharging current or discharging voltage, stopping charging and discharging, and any one or more combinations thereof. Among them, the alarm module 30 performs the battery protection function, and can determine a specific protection method based on different types of batteries, the maximum temperature that the battery can withstand, and the working efficiency of the battery at different temperatures. Different protection methods include different functional devices or modules in the alarm module 30. For example, when the alarm module 30 includes a buzzer, a vibration module, and a voice module, an alarm signal can be issued in different ways.

[0088] The disclosed embodiment also provides an electronic device, including: a battery protection device as described in the above embodiment.

[0089] In some embodiments, the electronic device may include a terminal device. The terminal device may include a mobile terminal and a fixed terminal, such as a mobile phone, a tablet computer, a PDA, a laptop computer, a desktop computer, a wearable device, a smart speaker, a television, and a vehicle-mounted terminal. The fixed terminal may include a desktop computer, etc.

[0090] In some embodiments, the electronic device also includes: a middle frame, carrying a battery 10; a main board, electrically connected to the middle frame, and an alarm module 30 located on the main board; when the temperature of the battery 10 rises and causes the temperature sensing connector 50 to deform, the external force is released, and the first contact point moves under the action of elastic force to be electrically connected to the middle frame, and is electrically connected to the alarm module 30 on the main board through the middle frame.

[0091] In this embodiment, the battery protection device can be used alone or integrated into an electronic device and used in conjunction with other components or modules in the electronic device to achieve safe and effective protection of the battery 10 in the electronic device.

[0092] When the battery protection device is integrated into an electronic device, the battery 10 in the battery protection device can be located in the middle frame of the electronic device, and the middle frame can have a battery compartment for accommodating the battery 10. The alarm module 30 in the battery protection device can be located on the main board of the electronic device, and the main board is directly or indirectly electrically connected to the middle frame.

[0093] When one end of the conductive elastic member 40 is electrically connected to the battery 10 protection plate, the second end of the conductive elastic member 40 passes through the limiting hole of the temperature sensing connector 50, and the conductive elastic member 40 has a first contact point at the deformed protruding portion under the action of external force, the temperature rise of the battery 10 causes the temperature sensing connector 50 to deform, and the external force is released. Under the action of the elastic force, the first contact point on the conductive elastic member 40 moves to be electrically connected to the middle frame, and the middle frame is electrically connected to the alarm module 30 on the mainboard, thereby forming an electrical path from the battery 10 protection plate to the conductive elastic member 40 and from the conductive elastic member 40 to the alarm module 30, thereby achieving safe and effective protection for the battery 10 in the electronic device.

[0094] In addition, since the alarm module 30 is electrically connected to the mainboard, the battery 10 protection function of the alarm module 30 can be controlled or modified through the mainboard of the electronic device, thereby achieving more flexible battery 10 protection.

[0095] In the above embodiment, the conductive elastic member 40 is electrically connected to the battery protection board of the battery 10. By arranging the alarm module 30 on the main board, and electrically connecting the main board to the middle frame carrying the battery 10, the battery protection device is integrated into the electronic device.

[0096] In some embodiments, the first end of the conductive elastic member 40 is electrically connected to the middle frame, and is electrically connected to the alarm module 30 on the mainboard through the middle frame.

[0097] In this embodiment, the first end of the conductive elastic member 40 can be directly or indirectly electrically connected to the middle frame, and electrically connected to the alarm module 30 on the main board through the middle frame. At this time, the first part of the second end of the conductive elastic member 40 abuts against the limiting protrusion of the temperature sensing connector 50, and the temperature rise of the battery 10 causes the temperature sensing connector 50 to deform. The external force generated by the abutment between the limiting protrusion of the temperature sensing connector 50 and the conductive elastic member 40 is released. Under the action of the elastic force, the first part of the second end of the conductive elastic member 40 moves to be electrically connected to the second contact point on the protection plate of the battery 10, forming an electrical path from the protection plate of the battery 10 to the conductive elastic member 40, and between the conductive elastic member 40 and the alarm module 30, thereby achieving safe and effective protection of the battery 10 in the electronic device.

[0098] In the above embodiment, the conductive elastic member 40 is electrically connected to the middle frame carrying the battery 10, and the middle frame is electrically connected to the alarm module 30 on the mainboard, so that the battery protection device is integrated into the electronic device.

[0099] It should be noted that the above embodiment is only one way of integrating the battery protection device into an electronic device. Based on the different structures, components and usage requirements of various electronic devices, the battery protection device can also be connected to other components (or devices or modules) and used in conjunction with them.
