Description

Technical Field

[0001] This application relates to the technical field of battery charging, and more particularly to a battery charging stand. Background Technology

[0002] In existing technologies, different battery models vary in parameters such as size and capacity. Among these differences, the charging current varies between models. If the charging current of the charging socket is set to be uniform, charging with a smaller current will result in a slower charging rate; conversely, charging with a larger current will cause batteries requiring less current to be charged with current exceeding their rated current, potentially leading to safety risks. Furthermore, different battery sizes may differ not only in charging current but also in discharging current and power supply methods, making it necessary to identify the battery's size. Utility Model Content

[0003] This application provides a battery charging stand for identifying batteries of different sizes.

[0004] This application provides a battery charging dock, including a first contact and a position sensor. The first contact is used to connect to a battery, and the position of the first contact varies depending on the size of the connected battery. The position sensor is used to sense the position of the first contact.

[0005] As can be seen from the battery charging dock described above, the ability of the first contact point to change position allows the charging dock to be compatible with batteries of various sizes. Furthermore, by cooperating with a position sensor, the position of the first contact point is detected, and the battery length is determined based on the position of the first contact point. Based on the battery length, the battery type is further determined, ensuring a stable connection for batteries of different models (specifications or sizes) and effectively improving the versatility of the battery charging dock.

[0006] In some embodiments, the battery charging dock further includes a charging circuit electrically connected to a position sensor and a first contact. The charging circuit is used to output a charging current corresponding to a position signal output by the position sensor to the first contact, the position signal being used to characterize the current position of the first contact.

[0007] As can be seen from the above embodiments, the charging circuit determines the position of the first contact point by using a position signal to determine the battery type, and then outputs a charging current matching the battery to the first contact point according to the battery type. By outputting different charging currents, the charging circuit can adjust the output current to adapt to different types of batteries, thereby meeting the charging needs of different batteries and improving the versatility and safety of the battery charging stand.

[0008] In some embodiments, the battery charging stand can be compatible with batteries of different length types, including at least a first length and a second length, wherein the first length is shorter than the second length.

[0009] The position sensor is positioned outside the first length range but within the second length range. Furthermore, the position sensor is triggered when a battery of the second length is installed in the battery charging dock.

[0010] As can be seen from the above embodiments, the battery charging dock can be compatible with batteries of various lengths. The position sensor selectively triggers based on the battery length, achieving compatibility with multiple battery types through its intelligent triggering mechanism. Physically limiting the position sensor avoids the problem of a short battery accidentally touching the sensing area of ​​a long battery, thus improving the versatility and safety of the battery charging dock.

[0011] In some embodiments, the position sensor is an occlusion detection sensor or a photoelectric sensor.

[0012] As can be seen from the above embodiments, in some embodiments, the position sensor uses a photoelectric sensor. When the first contact point slides to a designated position along the battery length, it blocks the light path received by the photoelectric sensor. The photoelectric sensor determines the battery length type by detecting changes in light flux. In other embodiments, whether the position sensor is obstructed is detected by other methods, and the battery length type is determined based on the obstruction. By setting an obstruction detection sensor or a photoelectric sensor, the response speed and reliability of the battery charging dock in different scenarios are improved, accurately matching the battery charging needs and enhancing the versatility and adaptability of the battery charging dock.

[0013] In some embodiments, the position sensor includes a rheostat connected to a first contact, wherein the resistance of the rheostat changes when the position of the first contact changes.

[0014] As can be seen from the above embodiments, the charging circuit can determine the size and model of the battery connected to the first contact by judging the current passing through the variable resistor after the resistance changes or the resistance of the variable resistor after the change, and then output a current that matches the battery, thereby improving the universality and adaptability of the battery charging socket.

[0015] In some embodiments, the battery charging dock further includes a base and a second contact. Both the first and second contacts are disposed on the base. The first contact is used to connect to a first terminal of the battery, and the second contact is used to connect to a second terminal of the battery. Furthermore, the second contact is electrically connected to a charging circuit, and its position on the base is fixed, while the first contact is movable relative to the base.

[0016] As can be seen from the above embodiments, the second contact is fixed in position on the base, and works in conjunction with the first contact, which is movable relative to the base, thereby forming a clamping structure for the battery and ensuring stable contact during charging. Furthermore, the fixed position of the second contact on the base allows the charging circuit to use this point as a reference point. This allows the position of the second contact, combined with the position sensed by the position sensor, to more accurately determine the battery size and type, thereby outputting a charging current that matches the battery and improving the compatibility of the charging base.

[0017] In some embodiments, a slide rail is provided on the base, and the second contact is slidably connected to the slide rail. The arrangement direction of the first and second contacts is the same as the extension direction of the slide rail.

[0018] As can be seen from the above embodiments, by providing a slide rail on the base and allowing the second contact to slide in a slidable connection with the slide rail, the position of the second contact can be adjusted along the slide rail direction, thereby connecting with batteries of different sizes and enhancing the compatibility and flexibility of the battery charging stand. Furthermore, aligning the first and second contacts in the same direction as the extension of the slide rail increases the sliding distance of the first contact on the slide rail, thus making the battery charging stand more adaptable and compatible with more batteries of different sizes and specifications.

[0019] In some embodiments, the battery charging dock further includes a first temperature sensor. The first temperature sensor is connected to a first contact or a second contact. The first temperature sensor is used to detect the temperature of the first contact or the second contact and transmit the detected temperature value to the charging circuit.

[0020] As can be seen from the above embodiments, the battery temperature is indirectly obtained by monitoring the temperature of the first contact or the second contact in real time, thereby realizing intelligent temperature control protection during the charging process, reducing the difficulty of battery temperature detection, and improving the safety and reliability of the battery charging stand.

[0021] In some embodiments, the battery charging dock further includes a second temperature sensor. The second temperature sensor is connected to the base and is used to detect the temperature of the battery mounted between the first and second contacts.

[0022] As can be seen from the above embodiments, the battery temperature is detected in a non-contact manner by using a second temperature sensor, which reduces misjudgments caused by local overheating and improves the safety and reliability of the battery charging stand.

[0023] In some embodiments, the charging circuit includes a controller and a power control unit. The controller is electrically connected to the power control unit, the power control unit is connected to a first contact and a second contact, and the controller is electrically connected to a position sensor. The controller is used to acquire the position of the first contact and control the power control unit to output a charging current matching the battery based on the position of the first contact.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, when describing pipelines, the terms "connected" and "linked" as used in this application have the meaning of establishing electrical connection. The specific meaning needs to be understood in conjunction with the context.

[0041] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0042] In daily life, batteries, as the core carrier of modern energy storage, come in various types, such as cylindrical lithium batteries and pouch batteries. Cylindrical lithium batteries, in particular, have several models. Taking a battery of a first length and a battery of a second length as examples, the first length battery is a lithium battery with a diameter of 18mm and a length of 65mm; the second length battery is a lithium battery with a diameter of 21mm and a length of 70mm. Because the volume of the second length battery is larger than that of the first length battery, it can accommodate more active material and electrolyte, thus resulting in a larger battery capacity for the second length battery compared to the first length battery.

[0043] Because the battery capacity of the second-length battery differs from that of the first-length battery, they can accept different charging currents. Specifically, the charging current for the second-length battery is greater than that for the first-length battery. If the same charger is used to charge both batteries, charging them according to the charging current of the first-length battery will result in a lower charging current for the second-length battery, leading to a slower charging rate. Conversely, charging them according to the charging current of the second-length battery will exceed the specified charging current for the first-length battery, potentially posing a safety risk.

[0044] Figure 1 This is a first structural block diagram of the battery charging stand disclosed in an embodiment of this application.

[0045] In view of this, such as Figure 1 As shown in the figure, this application embodiment provides a battery charging dock 1, including: a first contact 11 and a position sensor 12. The first contact 11 is used to connect to a battery 2, and the position of the first contact 11 varies with the size of the connected battery 2. The position sensor 12 is used to sense the position of the first contact 11.

[0046] In the above embodiments, the first contact 11 of this application can move according to the size of the battery 2, thereby allowing the battery charging stand 1 to adapt to batteries 2 of various lengths, so as to improve the adaptability and versatility of the battery charging stand 1.

[0047] Furthermore, this application includes a position sensor 12 to sense the position of the first contact 11, thereby determining the length of the battery 2 currently connected to the first contact 11 based on the different positions of the first contact 11, and then determining the type of battery based on the length of the battery 2.

[0048] This application utilizes the ability of the first contact 11 to change position, enabling the battery charging stand 1 to be compatible with batteries 2 of various sizes. Furthermore, by cooperating with the first contact 11, the position sensor 12 detects the position of the first contact 11 and determines the length of the battery 2 based on the first contact 11. Based on the length of the battery 2, the type of battery 2 is further determined. This ensures a stable connection of the charging circuit for batteries of different models (specifications or sizes), effectively improving the versatility of the battery charging stand 1.

[0049] Figure 2 This is a second structural block diagram of the battery charging stand disclosed in an embodiment of this application.

[0050] In some embodiments, such as Figure 2 As shown, the battery charging base 1 also includes a charging circuit 10, which is electrically connected to the position sensor 12 and the first contact 11. The charging circuit 10 is used to output a charging current corresponding to the position signal output by the position sensor 12 to the first contact 11, where the position signal represents the current position of the first contact 11.

[0051] In the above embodiments, the battery charging base 1 further includes a charging circuit 10, which outputs a charging current to the first contact 11 to charge the battery 2 connected to the first contact 11. Furthermore, a position sensor 12 outputs a position signal to the charging circuit 10. This position signal is sent based on the position of the first contact 11, thus representing the current position of the first contact 11 and consequently the length of the battery 2 connected to it. The charging circuit 10 can determine the length of the battery 2 connected to the first contact 11 based on the position signal, thereby determining the type of battery 2 and outputting a charging current matching the battery 2. By outputting different charging currents, the charging circuit 10 can adjust the charging current to adapt to different types of batteries, thereby meeting the charging needs of different batteries and improving the versatility and safety of the battery charging base 1. In some embodiments, the battery charging base 1 can match batteries 2 of different lengths, including at least a first length and a second length, where the first length is shorter than the second length.

[0052] The position sensor 12 is positioned outside the first length range but within the second length range. Furthermore, the position sensor 12 is triggered when a battery 2 of the second length is installed in the battery charging holder 1.

[0053] In the above embodiments, the battery charging stand 1 can accommodate batteries of various lengths. In some embodiments, the length types include a first length and a second length, where the first length is shorter than the second length. Because the first contact 11 can be displaced depending on the length of the battery 2, the position sensor 12 is positioned along the path of the first contact 11 when it is displaced. The position of the position sensor 12 is a location that the first contact 11 cannot reach when a battery of the first length is installed, but a location that the first contact 11 will pass through when a battery of the second length is installed. Therefore, when a battery of the second length 2 is installed in the battery charging stand 1, the first contact 11 will pass through the position sensor 12, thereby triggering the position sensor 12 and sending a position signal. This allows the charging circuit 10 to determine the type of battery 2 based on the position signal and output a charging current that matches the type of battery 2.

[0054] In another embodiment, the length types include a first length, a second length, and a third length, where the first length is shorter than the second length, and the second length is shorter than the third length. Two position sensors 12 can be provided, one positioned outside the range of the first length but within the range of the second length; the other positioned outside the range of the second length but within the range of the third length. Thus, when batteries of the second length and the third length are installed in the battery charging holder 1, different position signals are sent to distinguish the types of batteries 2, thereby causing the charging circuit 10 to output different charging currents to match the charging needs of different batteries 2.

[0055] The position sensor 12 selectively triggers based on the length of the battery 2, achieving compatibility with multiple battery types through its intelligent triggering mechanism. Furthermore, by physically limiting the position sensor 12, the problem of a short battery accidentally touching the sensing area of ​​a long battery is avoided, improving the versatility and safety of the battery charging stand 1.

[0056] It should be noted that the above description does not mean that the battery charging stand 1 proposed in this application can only be used with a maximum of three types of batteries. For example, increasing the number of position sensors 12 to identify more battery models is also within the scope of this utility model and will not be elaborated here.

[0057] Figure 10 This is a first flowchart of charging the battery charging stand 1 disclosed in the embodiments of this application.

[0058] In some examples, such as Figure 10As shown, the battery charging holder 1 of this application is suitable for batteries of a first length and batteries of a second length. The battery capacity of the second length battery is greater than that of the battery of the first length, and the second length is greater than the first length. Therefore, the required storage space for charging the first length battery and the second length battery will certainly be different, and because current needs to be conducted between the battery to achieve charging, when either the first battery or the second battery is connected to the first contact 11, the position of the first contact 11 will change.

[0059] S10, the charging circuit 10 determines whether the first contact 11 is located in a preset position. If the first contact 11 is located in the preset position, S101, the length of the battery currently being charged is determined to be the first length, and a charging current matching the battery of the first length is output; otherwise, S102, the length of the battery currently being charged is determined to be the second length, and the charging circuit 10 outputs a charging current matching the battery of the second length.

[0060] Figure 3 This is a third structural block diagram of the battery charging stand disclosed in an embodiment of this application.

[0061] In some embodiments, such as Figure 3 As shown, the battery charging base 1 further includes a base 13 and a second contact 14. Both the first contact 11 and the second contact 14 are disposed on the base 13. The first contact 11 is used to connect to a first end of the battery 2, and the second contact 14 is used to connect to a second end of the battery 2. Furthermore, the second contact 14 is electrically connected to the charging circuit 10. The position of the second contact 14 on the base 13 is fixed, while the first contact 11 is movable relative to the base 13.

[0062] In the above embodiment, the second contact 14 is fixed in position on the base 13, and the second contact 14 works in conjunction with the first contact 11 which is movable relative to the base 13, thereby forming a clamping structure for the battery 2 and ensuring stable contact of the battery 2 during the charging process.

[0063] In some examples, the first contact 11 is connected to the negative terminal of the battery 2, and the second contact 14 is connected to the positive terminal of the battery 2. This makes the connection more secure when charging batteries such as cylindrical lithium batteries, where the positive terminal protrudes and the negative terminal is flat, thus increasing the stability and reliability of the battery charging base 1.

[0064] Furthermore, the second contact 14 is fixed in position on the base 13, allowing the charging circuit 10 to use the second contact 14 as a reference point. For example, the connection point between the battery 2 and the second contact 14 is the starting point of the battery. This allows the position of the second contact 14 to be combined with the position sensed by the position sensor 12 to further accurately determine the battery size, thereby determining the battery type and outputting a charging current that matches the battery, thus improving the compatibility of the charging base.

[0065] Figure 4 This is a fourth structural block diagram of the battery charging stand disclosed in the embodiments of this application.

[0066] In some embodiments, such as Figure 4 As shown, a slide rail 15 is provided on the base 13, and the second contact 14 is slidably connected to the slide rail 15. The arrangement direction of the first contact 11 and the second contact 14 is the same as the extension direction of the slide rail 15.

[0067] In the above embodiment, by providing a slide rail 15 on the base 13 and making the second contact 14 slidably connected to the slide rail 15, the position of the second contact 14 can be adjusted along the direction of the slide rail 15, thereby connecting with batteries of different sizes, enhancing the compatibility and flexibility of the battery charging stand 1, ensuring stable contact during battery charging, and improving charging safety.

[0068] Furthermore, by aligning the first contact 11 and the second contact 14 in the same direction as the extension direction of the slide rail 15, the sliding distance of the first contact 11 on the slide rail 15 is increased, thereby making the battery charging base 1 more adaptable and compatible with more batteries of different sizes and specifications.

[0069] In some examples, the end of the slide rail 15 near the first contact 11 is provided with a safe distance from the first contact 11, thereby ensuring that the second contact 14 is effectively isolated from the first contact 11, avoiding contact between the first contact 11 and the second contact 14 to form a short circuit, and improving the safety and reliability of the battery charging dock 1.

[0070] In some embodiments, the position sensor 12 is disposed on the base 13, and the position of the position sensor 12 is fixed.

[0071] In the above embodiment, the position sensor 12 is fixed on the base 13, which allows the position sensor 12 to cooperate with the second contact 14. The second contact 14 is used to fix this point, and the current length of the battery is determined based on the distance from the second contact 14 to the position sensor 12. Then, a charging current matching the battery is output, which improves the intelligence level of the battery charging stand 1 and realizes accurate adaptation to multiple battery specifications.

[0072] Figure 11This is a second flowchart illustrating the charging process of the battery charging stand 1 disclosed in this application embodiment.

[0073] In some examples, such as Figure 11 As shown, the battery charging stand 1 of this application is applicable to batteries of a first length and batteries of a second length, wherein the battery capacity of the first length battery is less than the battery capacity of the second length battery. The vertical distance between the position sensor 12 and the plane containing the side of the second contact 14 facing the first contact 11 is a preset distance, and the first length is less than the preset distance, which is less than the second length.

[0074] S20. Determine whether the position sensor 12 has detected the first contact 11. If the position sensor 12 has detected the first contact 11, S201. Determine that the length of the battery currently being charged is the second length, and the charging circuit 10 outputs a charging current that matches the battery of the second length. S202. Otherwise, determine that the length of the battery currently being charged is the first length, and the charging circuit 10 outputs a charging current that matches the battery of the first length.

[0075] Figure 5 This is the fifth structural block diagram of the battery charging stand 1 disclosed in the embodiments of this application.

[0076] In some embodiments, such as Figure 5 As shown, the battery charging dock 1 also includes a first temperature sensor 16. The first temperature sensor 16 is connected to either the first contact 11 or the second contact 14. The first temperature sensor 16 is used to detect the temperature of the first contact 11 or the second contact 14 and transmits the detected temperature value to the charging circuit 10.

[0077] In the above embodiment, since this application is connected to the battery 2 through the first contact 11 and the second contact 14, and charges the battery 2 through the first contact 11 and the second contact 14. Because current flows through the first contact 11 and the second contact 14 during charging, the temperature of the first contact 11 and the second contact 14 will increase as charging progresses. In this embodiment, by obtaining the temperature value of the first contact 11 or the second contact 14, the current temperature of the battery 2 is confirmed, and the detected temperature value is transmitted to the charging circuit 10, thereby enabling the charging circuit 10 to determine whether to stop charging based on the temperature value.

[0078] By indirectly obtaining the battery temperature through real-time monitoring of the temperature of the first contact 11 or the second contact 14, intelligent temperature control protection during the charging process is achieved, reducing the difficulty of battery temperature detection and improving the safety and reliability of the battery charging stand 1.

[0079] Figure 12 This is a flowchart illustrating the operation of the first temperature sensor 16 disclosed in an embodiment of this application.

[0080] In some examples, such as Figure 12 As shown, in step S30, the charging circuit 10 determines whether the temperature of the first contact 11 or the second contact 14 is greater than the first threshold. In step S301, if the temperature of the first contact 11 or the second contact 14 is greater than the first threshold, it is determined that the battery currently connected to the first contact 11 or the second contact 14 is overheated, and the charging circuit 10 stops outputting the charging current. In step S302, otherwise, it is determined that the battery currently connected to the first contact 11 or the second contact 14 is safe, and the charging circuit 10 continues to output the charging current.

[0081] In some examples, when the first temperature sensor 16 is connected to the second contact 14, the first temperature sensor 16 is also connected to the base 13, thereby increasing the stability of the first temperature sensor 16.

[0082] Figure 6 This is the sixth structural block diagram of the battery charging stand 1 disclosed in the embodiments of this application.

[0083] In some embodiments, such as Figure 6 As shown, the battery charging base 1 also includes a second temperature sensor 17. The second temperature sensor 17 is connected to the base 13 and is used to detect the temperature of the battery 2 installed between the first contact 11 and the second contact 14.

[0084] In the above embodiment, the second temperature sensor 17 is disposed on the base 13 to detect the temperature of the battery 2 connected to the first contact 11 and the second contact 14, thereby detecting the temperature of the battery 2 in a non-contact manner, avoiding misjudgment caused by local overheating, and improving the safety and reliability of the battery charging stand 1.

[0085] Figure 13 This is a flowchart illustrating the operation of the second temperature sensor 17 disclosed in an embodiment of this application.

[0086] In some examples, such as Figure 13 As shown, in step S40, the charging circuit 10 determines whether the battery temperature is greater than the second threshold. In step S401, if the battery temperature is greater than the second threshold, the battery is determined to be overheated, and the charging circuit 10 stops outputting the charging current. In step S402, otherwise, the battery is determined to be safe, and the charging circuit 10 continues to output the charging current.

[0087] Figure 7 This is the seventh structural block diagram of the battery charging stand disclosed in the embodiments of this application.

[0088] In some examples, such as Figure 7As shown, when the battery charger includes a first temperature sensor 16 and a second temperature sensor 17, the charging circuit 10 stops outputting charging current when the temperature of the first contact 11 or the second contact 14 is greater than a first threshold and the battery temperature is greater than a second threshold, based on the joint temperature detection of the first temperature sensor 16 and the second temperature sensor 17. Otherwise, the charging circuit 10 continues to output charging current. The first threshold can be equal to or greater than the second threshold.

[0089] In some embodiments, the position sensor 12 includes an occlusion detection sensor or a photoelectric sensor.

[0090] In some embodiments, the position sensor 12 can be a photoelectric sensor. When the first contact point slides to a designated position along the length of the battery, it will block the light path received by the photoelectric sensor. The photoelectric sensor determines the battery length type by detecting changes in light flux.

[0091] In another embodiment, the position sensor 12 may be an obstruction detection sensor, which detects whether the position sensor 12 is obstructed, and then determines the length type of the battery 2 based on the obstruction.

[0092] By selecting an obstruction detection sensor or a photoelectric sensor as the position sensor 12, the response speed and reliability of the battery charging stand 1 in different scenarios are improved, the charging needs of the battery 2 are accurately matched, and the versatility and adaptability of the battery charging stand 1 are enhanced.

[0093] In some embodiments, the position sensor 12 includes a rheostat connected to a first contact 11, wherein the resistance of the rheostat changes when the position of the first contact 11 changes.

[0094] In the above embodiment, the position sensor 12 includes a variable resistor. When the first contact 11 slides, the resistance of the variable resistor changes, which in turn causes the current passing through the variable resistor to change. The charging circuit 10 can make a judgment based on the changed current or the changed resistance of the variable resistor, thereby determining the size and model of the battery connected to the first contact 11, and then outputting a current that matches the battery, thus improving the versatility and adaptability of the battery charging base 1.

[0095] In some embodiments, the charging circuit 10 includes a controller 101 and a power control unit 102. The controller 101 is electrically connected to the power control unit 102, the power control unit 102 is connected to a first contact 11 and a second contact 14, and the controller 101 is electrically connected to a position sensor 12. The controller 101 is used to obtain the position of the first contact 11 and control the power control unit 102 to output a charging current matching the battery 2 based on the position of the first contact 11.

[0096] In the above embodiment, the controller obtains the position of the first contact 11, and then uses the position of the first contact 11 to control the power control unit to output a charging current that matches the battery, thereby improving the versatility and adaptability of the battery charging stand 1.

[0098] In some examples, such as Figure 8 As shown, when the battery charging dock 1 includes a controller 101, a power control unit 102, a position sensor 12, a first temperature sensor 16, and a second temperature sensor 17, the position sensor 12 sends the position of the first contact 11 to the controller 101. Based on the position of the first contact 11, the controller 101 controls the power control unit 102 to output a charging current matching the battery. Furthermore, the first temperature sensor 16 sends the temperature of either the first contact 11 or the second contact 14 to the controller 101, and the second temperature sensor 17 sends the battery temperature to the controller 101. Based on the temperature of either the first contact 11 or the second contact 14, and / or the battery temperature, the controller 101 controls whether the power control unit 102 outputs a charging current.

[0099] Figure 9 This is the ninth structural block diagram of the battery charging stand disclosed in the embodiments of this application.

[0100] In some embodiments, such as Figure 9 As shown, the side of the first contact 11 facing the second contact 14 is provided with an elastic component 18.

[0101] In the above embodiment, when the battery is installed between the first contact 11 and the second contact 14, the elastic component 18 will be subjected to the pressure of the battery, thereby forming an opposing force to hold the battery in place, so as to improve the stability of the battery connection.

[0102] For example, the elastic component 18 may include a spring.
