Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and more specifically, to an energy storage device. Background Technology

[0002] With the surge in demand for outdoor activities, emergency backup power, and mobile offices, portable energy storage batteries are widely used due to their clean power supply and large-capacity energy storage characteristics. However, traditional energy storage devices have fixed and limited output interfaces, often requiring users to use external power strips to extend power supply. This poses a significant pain point in mobile scenarios, as fixed interfaces cannot meet the simultaneous power needs of multiple types of devices, easily leading to interface shortages. External power strips are prone to poor contact, short circuits, and even fire risks in outdoor bumpy and humid environments. Furthermore, the fixed location of the devices prevents the power points from being adjusted as needed, and tangled cables pose a tripping hazard. While existing track sockets offer modular expansion advantages, they require fixed installation on walls and rely on mains wiring, making them unsuitable for the mobile nature of portable energy storage devices.

[0003] Therefore, there is an urgent need for a safe power supply solution that can be directly integrated into energy storage devices, supports plug-and-play functionality and flexible location adjustment, in order to solve the safety and flexibility issues of expanding power supply to multiple devices in outdoor scenarios. Utility Model Content

[0004] This utility model aims to at least solve the problem in related technologies that conventional energy storage devices have fixed output interface positions and limited numbers, requiring users to use external power strips for expansion, which makes it impossible to adjust the power supply points as needed.

[0006] The energy storage device provided by this utility model has conductive pins that are slidably arranged in the track groove and can be located at any position in the track groove, thereby allowing the position of the output interface to be adjusted arbitrarily, thus making it more flexible.

[0008] In this technical solution, by connecting the circuit protection device in series with the power supply circuit, the power supply circuit is cut off within 0.1 seconds when the overcurrent is greater than 120% of the rated current or the short-circuit impedance is less than 0.1Ω, thus preventing the equipment from burning out.

[0011] In the above technical solution, optionally, the outer shell assembly includes: a main outer shell and a track base, the track base being detachably installed on the main outer shell, and the track groove being provided on the track base.

[0012] In this technical solution, by placing the track groove on the track base, when the track groove is damaged, only the track base needs to be replaced, thus avoiding the need for complete machine repair.

[0013] Optionally, in the above technical solution, the outer surface of the main body shell is provided with a mounting groove extending into the interior of the main body shell, and the track base is located in the mounting groove.

[0014] In this technical solution, the track base is located in the mounting groove, so that the track base does not protrude from the outer surface of the main body shell, that is, the track base is hidden, thereby improving the overall aesthetics.

[0015] Optionally, in the above technical solution, the energy storage device also includes a baffle, which is installed on the main body shell and is provided with a corresponding mounting slot for closing or opening the mounting slot.

[0016] In this technical solution, when there is no need for charging, the baffle can close the mounting slot and enclose the track base inside the mounting slot, thereby preventing users from accidentally touching it and getting electric shocks. It can also prevent rainwater from entering the track slot, thus improving safety.

[0017] Optionally, in the above technical solution, the track base is located on the outer surface of the main body shell.

[0018] In this technical solution, the track base is located on the outer surface of the main shell, so that the structure of the main shell does not need to be changed, thereby improving the overall manufacturing efficiency.

[0021] In the above technical solution, optionally, the housing assembly and the socket assembly are connected and fixed by magnetic components.

[0022] In this technical solution, the track base and the socket assembly are connected and fixed by magnetic components, which improves the stability of the socket assembly and eliminates the need for additional fixing structures.

[0024] Optionally, in the above technical solution, the energy storage device also includes a sealing strip, which is set in the groove of the track groove, and the conductive pin can pass through the sealing strip and abut against the conductive component.

[0025] In this technical solution, the sealing strip improves the sealing effect of the track groove, protecting the entire track groove from rainwater and dust. Furthermore, because the sealing ring is elastic, it can also clamp the socket assembly.

[0050] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0051] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0052] like Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 14 As shown, the energy storage device 1 provided by this utility model includes a housing assembly 2, a battery 3, a conductive element 4, and at least one socket assembly 5. The surface of the housing assembly 2 is provided with a track groove 26. The battery 3 is disposed inside the housing assembly 2. For example, the battery 3 can be a storage battery, etc. The conductive element 4 is disposed in the track groove 26 and is electrically connected to the battery 3. The socket assembly 5 includes a conductive pin 52 and an output interface 54. The conductive pin 52 and the output interface 54 are electrically connected. The conductive pin 52 can slide in the track groove 26, and during the sliding process, the conductive pin 52 can always abut against the conductive element 4, thereby electrically connecting the output interface 54 to the conductive element 4 and supplying power to external devices through the output interface 54.

[0053] The energy storage device 1 provided by this utility model has conductive pins 52 slidably disposed in the track groove 26, which can be located at any position in the track groove 26, thereby allowing the position of the output interface 54 to be arbitrarily adjusted, thus providing greater flexibility.

[0054] Among them, the conductive pin 52 can be an elastic conductive pin 52, so that it can undergo slight deformation when in contact with the conductive component 4, thereby improving the contact stability between the conductive pin 52 and the conductive component 4, and can also achieve stable electrical connection during sliding.

[0055] The conductive component 4 can be a copper strip containing positive and negative electrodes, which is laid out along the length of the track groove 26.

[0056] More specifically, the power supply copper strip can be two parallel power supply copper strips, located on two opposite walls of the track groove 26. One is connected to the positive terminal of the battery 3, and the other is connected to the negative terminal of the battery 3. Similarly, there are two conductive plates on the conductive pin 52. After the conductive pin 52 is inserted into the track groove 26, the two conductive plates 524 of the conductive pin 52 can contact the two parallel power supply copper strips respectively, and the two conductive plates 524 can also be electrically connected to the output interface 54 respectively. Thus, when the output interface 54 is connected to an external device to be charged, a closed charging circuit can be realized.

[0057] In the above technical solutions, optionally, such as Figure 14 As shown, the energy storage device 1 also includes a circuit protection device 6, which is disposed inside the housing assembly 2 and electrically connected to the power supply circuit 62 between the battery 3 and the conductive component 4; wherein, the circuit protection device 6 is configured to disconnect the power supply circuit 62 when an overcurrent or short circuit is detected in the current flowing through the circuit protection device 6.

[0058] In this technical solution, the energy storage device 1 also includes a circuit protection device 6, which is disposed within the housing assembly 2 and electrically connected to the power supply circuit 62 between the battery 3 and the conductive component 4. When an overcurrent or short circuit is detected in the current flowing through the circuit protection device 6, the power supply circuit 62 is disconnected. By connecting the circuit protection device 6 in series with the power supply circuit 62, when the overcurrent is greater than 120% of the rated current or the short-circuit impedance is less than or equal to 0.1Ω, the power supply circuit 62 is cut off within 0.1 seconds to prevent the equipment from burning out.

[0059] In the above technical solutions, optionally, such as Figure 11 and Figure 13 As shown, the socket assembly 5 includes a socket body 56, conductive pins 52 disposed on one side of the socket body 56, and an output interface 54 disposed on the side of the socket body 56 away from the conductive pins 52; a rotating unit 58 is rotatably disposed on the periphery of the socket body 56, and the rotating unit 58 is connected to the conductive pins 52; the rotating unit 58 can drive the conductive pins 52 to rotate in a first direction, so that the conductive pins 52 can be electrically connected to the conductive element 4, and the rotating unit 58 can drive the conductive pins 52 to rotate in a second direction, so that the conductive pins 52 are disconnected from the conductive element 4, and the first direction and the second direction are opposite.

[0060] Understandably, as follows Figure 16 and Figure 17 As shown, the conductive pin 52 includes an insertion part 522 and two conductive pieces 524. The insertion part 522 can be inserted into the track groove 26. The conductive element 4 includes a first copper strip 42 and a second copper strip 44, which are located on two opposite side walls inside the track groove 26. The two conductive pieces 524 are insulated from each other. The rotating unit 58 is connected to the two conductive pieces 524 and can drive the two conductive pieces 524 to rotate. When the rotating unit 58 drives the two conductive pieces 524 to rotate in the first direction, as... Figure 16 As shown, the two conductive pieces 524 can contact the first copper strip 42 and the second copper strip 44, thereby achieving circuit continuity. When the rotating unit 58 drives the conductive pin 52 to rotate in the second direction, as... Figure 17 As shown, the two conductive pieces 524 are disconnected from the first copper strip 42 and the second copper strip 44, thereby achieving a circuit break and preventing a short circuit when not charging.

[0061] In addition, it should be noted that since the two conductive pieces 524 need to rotate relative to the insertion part 522, and the two conductive pieces 524 are located inside the insertion part 522, it is necessary to provide clearance holes (not shown) on the insertion part 522 to avoid the rotation of the two conductive pieces 524, and to ensure that they are always electrically connected to the output interface 54 during the rotation of the two conductive pieces.

[0062] This application further defines the socket assembly 5, allowing users to switch between power on / off by rotating the rotating unit 58, which greatly improves operational efficiency in outdoor mobile scenarios.

[0063] In the above technical solutions, optionally, such as Figure 2 , Figure 7 and Figure 15 As shown, the outer casing assembly 2 includes a main outer casing 22 and a track base 24. The track base 24 is detachably mounted on the main outer casing 22, and the track groove 26 is provided on the track base 24.

[0064] In this technical solution, by setting the track groove 26 on the track base 24, when the track groove 26 is damaged, only the track base 24 needs to be replaced, thus avoiding the need for complete machine repair.

[0065] In the above technical solutions, optionally, such as Figure 15 As shown, the outer surface of the main body shell 22 is provided with a mounting groove 28 extending into the interior of the main body shell 22, and the track base 24 is located in the mounting groove 28.

[0066] In this technical solution, the track base 24 is located in the mounting groove 28. As a whole, the track base 24 does not protrude from the outer surface of the main body shell 22, that is, the track base 24 is hidden, thereby improving the overall aesthetics.

[0067] The track base 24 can be entirely housed within the mounting groove 28, and its outer surface can be coplanar with the outer surface of the main body shell 22, thus improving the overall aesthetics. Alternatively, the track base 24 can be partially housed within the mounting groove 28, partially protruding from the outer surface of the main body shell 22.

[0068] In the above technical solutions, optionally, such as Figure 15 As shown, the energy storage device also includes a baffle 9, which is installed on the main body shell 22 and is provided in relation to the mounting slot 28, for closing or opening the mounting slot 28.

[0069] In this technical solution, the baffle 9 is installed on the main body shell 22 and is set corresponding to the mounting groove 28, so that the baffle 9 can control the opening and closing of the mounting groove 28. When the track base 24 is placed in the mounting groove 28, the baffle 9 is closed to protect the track base 24. When charging, the track base 24 is opened to charge.

[0070] The baffle 9 is rotatably mounted on the main body shell 22, for example, rotatably mounted at the opening of the mounting groove 28. When the baffle 9 rotates, it completely closes the mounting groove 28, protecting the track base 24 from electric shock or rain damage when there is no charging requirement. Optionally, when the baffle 9 closes the mounting groove 28, the outer surface of the baffle 9 is coplanar with the outer surface of the main body shell 22 (not shown), thus improving the overall aesthetics. Of course, the baffle 9 can also be slidably mounted on the main body shell 22. The specific method of opening and closing the mounting groove 28 through sliding is common knowledge in the art; for example, sliding can be achieved through structures such as grooves, which will not be described in detail here.

[0071] In the above technical solutions, optionally, such as Figure 7 As shown, the track base 24 is located on the outer surface of the main body shell 22.

[0072] In this technical solution, the track base 24 is located on the outer surface of the main shell 22, that is, the track base 24 protrudes completely from the outer surface of the main shell 22. This eliminates the need to modify the structure of the main shell 22, thereby improving the overall manufacturing efficiency.

[0073] In the above technical solution, optionally, the main body shell 22 is snap-fitted and / or magnetically connected to the track base 24.

[0074] In this technical solution, the main body shell 22 and the track base 24 are connected by strong magnetic attraction and / or snap fasteners to prevent the track base 24 from accidentally falling off during bumps.

[0075] Of course, optionally, the main body shell 22 and the track base 24 are connected by strong magnetic attraction and buckle, thus realizing a double-safety structure and supporting quick assembly and disassembly.

[0076] In the above technical solution, optionally, the housing assembly 2 and the socket assembly 5 are connected and fixed by magnetic components.

[0077] In this technical solution, the track base 24 and the socket assembly 5 are connected and fixed by magnetic components, which can improve the stability of the socket assembly 5 and eliminates the need for other fixing structures.

[0078] That is, both the track base 24 and the socket assembly 5 are provided with magnetic elements. When charging, after the conductive pin 52 of the socket assembly 5 is inserted into the track groove 26, the magnetic elements on the track base 24 and the socket assembly 5 can attract each other, thereby fixing the socket assembly 5 to the track base 24. Since the attraction between the two magnetic elements is in the depth direction of the track groove 26, it will not affect the sliding of the conductive pin 52 in the track groove 26 in the length direction of the track groove 26.

[0079] Optionally, the magnetic element of the socket assembly 5 is disposed on the socket body 56.

[0080] In the above technical solution, optionally, the groove depth of the track groove 26 is greater than or equal to 8mm.

[0081] In this technical solution, the depth of the track groove 26 is limited to ensure that the conductive pin 52 is completely submerged in the track groove 26, effectively isolating external objects from accidental contact with live parts; in addition, buffer space can be reserved for the elastic deformation of the conductive pin 52 to maintain stable contact pressure. For example, the depth of the track groove 26 is greater than or equal to 10 mm and less than or equal to 15 mm.

[0082] In the above technical solutions, optionally, such as Figure 8 As shown, the energy storage device 1 also includes a sealing strip 7, which is disposed in the groove of the track groove 26. The conductive pin 52 can pass through the sealing strip 7 and abut against the conductive component 4.

[0083] In this technical solution, the sealing strip 7 can improve the sealing effect of the track groove 26 and protect the entire track groove 26 from rainwater and dust. On the other hand, since the sealing strip 7 is elastic, it can also clamp the socket assembly 5.

[0084] In the above technical solution, optionally, the number of socket components 5 is greater than or equal to 3.

[0085] In this technical solution, the number of socket components 5 is greater than or equal to 3, and optionally, the number of socket components 5 is greater than or equal to 5, so as to meet the power needs of multiple devices at the same time.

[0086] In the above technical solution, optionally, at least one socket component 5 is a device module with integrated power supply function, and the device module with integrated power supply function includes one or a combination of the following: AC output module 82, DC output module 84, radio module 86 or walkie-talkie module 88.

[0087] This application incorporates AC output interfaces (i.e., AC output module 82) and DC output interfaces (i.e., DC output module 84) into track sockets. Users can rationally assemble the required AC / DC input interfaces according to their actual needs, avoiding interface waste and shortages. Furthermore, when some AC / DC interfaces are damaged, the corresponding output modules can be purchased and installed, eliminating the need for the entire unit to be returned to the factory for repair, thus improving after-sales maintenance efficiency. In addition to the AC / DC output interfaces, outdoor equipment such as outdoor speakers, radios, and walkie-talkies can also be directly plugged into the track sockets for charging, making it more convenient and greatly expanding the convenience of charging outdoor equipment.

[0088] It should be noted that the outdoor speakers, radios, and walkie-talkies mentioned here are not conventional outdoor speakers, radios, and walkie-talkies, but rather outdoor speakers, radios, and walkie-talkies that are compatible with this application and have conductive pins 52.

[0089] The following describes various usage states of the energy storage device 1 of this application.

[0090] like Figure 5 , Figure 7 and Figure 10 As shown, the two AC output ports and one DC output port are inserted into the track slot 26. In this state, the user can use the two AC output ports and one DC output port. The power supply status of each output port 54 can be controlled individually through the track socket switch (i.e., the rotating unit 58), which is safer and more convenient.

[0091] like Figure 1 As shown, the two AC output ports and one DC output port are inserted into the track slot 26. The AC output port and DC output port can be powered by inserting them into the track slot 26 through the conductive pin 52. The specific number of interfaces can be freely selected for assembly. After assembly, turn on the track socket switch to start charging.

[0092] like Figure 2 As shown, this device 1, which utilizes a radio and walkie-talkie, includes conventional AC and DC output interfaces. It can also directly connect to and charge electrical appliances such as radios and walkie-talkies, greatly expanding charging convenience. Figure 8 As shown, the track groove 26 is exposed. This track groove 26 adopts a closed design, which can prevent dust and water when used outdoors.

[0093] Figure 3 and Figure 4 The usage status of 3 AC output ports and 4 AC output ports are shown respectively. Figure 5 and Figure 12 This shows the usage status of 2 AC output ports and 1 DC output port. Figure 6 With 2 AC output ports and 2 DC output ports, users can freely configure the number of output ports according to their actual needs, making it convenient and easy to use.

[0094] The energy storage device 1 of this application enables immediate use in outdoor scenarios. Through a closed track and modular socket locking design, it solves the problems of traditional power strips being prone to loosening and short circuits in mobile environments, while also considering power supply expansion for multiple devices and electrical safety. The key points of the technical solution of this application are as follows:

[0095] The track base 24 is connected and fixed to the main body shell 22 by strong magnetic attraction and mechanical buckle, which makes the connection stronger and less likely to separate, and also supports quick assembly and disassembly.

[0096] The depth of the track groove 26 is ≥8mm. In the non-plugging state, the baffle 9 encloses the track base 24 inside the mounting groove 28, which can prevent accidental contact and electric shock.

[0097] The energy storage device 1 is also equipped with a circuit protection device 6. The response speed of the circuit protection device 6 is <0.1s. During the charging process, if an overcurrent or short circuit occurs, the circuit protection device 6 can cut off the power in time to prevent fire.

[0098] A silicone sealing strip 7 is provided at the opening of the track groove 26, which can make the track groove 26 dustproof and waterproof, and protect the conductive components 4 inside the track groove 26.
