Description

Technical Field

[0001] The present application relates to the field of mobile energy storage technology, and in particular to an energy storage device. Background Art

[0002] In recent years, energy storage power supplies have become increasingly popular in scenarios such as camping, outdoor work, and home backup. Existing energy storage power supplies often have split designs, such as a separate main unit and separate power pack forming a scalable power supply, or a separate inverter and separate battery pack forming a single power supply. The two components are electrically connected via male and female terminals. When separated, the female terminals are exposed to the outside world, making them susceptible to contamination and unsuitable for reuse.

[0003] In the related art, a protective structure is provided on the host to protect the female terminal. However, when the two parts are connected, the protective structure needs to be removed first and then the two parts are connected. This operation is rather cumbersome, resulting in poor product usability. Utility Model Content

[0004] In view of this, the present application provides an energy storage device, which can protect the first terminal when the first split body and the second split body are separated, and can also simplify the assembly steps of the first split body and the second split body.

[0005] One embodiment of the present application provides an energy storage device. The energy storage device includes a first split body and a second split body. The first split body includes a first shell and a first terminal provided on the first shell. The second split body includes a second shell and a second terminal provided on the second shell. The first split body also includes a protective cover. The protective cover is movably provided on the first shell and is configured to be able to move to a first position or a second position. When the first shell and the second shell are separated, the protective cover is in the first position and shields the first terminal from exposing one end of the first shell. When the first shell and the second shell are connected and matched, the protective cover is configured to be able to move to the second position under the action of external force to avoid the connection path of the first terminal and the second terminal.

[0006] In the above embodiment, when the first and second housings are separated, the protective cover can shield the first terminal, isolating the first terminal from the external environment of the first housing, thereby protecting the first terminal from contamination by the external environment. Furthermore, the protective cover is movable relative to the first housing. By moving when the first and second housings are connected, the protective cover avoids the connection path between the first and second terminals, allowing the first and second terminals to be connected. This eliminates the need to disassemble the protective structure for the first terminal, thereby simplifying the assembly steps of the first and second sub-bodies. Furthermore, it helps to extend the time the protective cover protects the first terminal, thereby enhancing the protective effect of the first terminal.

[0007] In some embodiments, the second split body further includes a pusher disposed on the second housing. When the first housing and the second housing are connected and mated, the pusher abuts against the protective cover to move the protective cover to the second position.

[0008] In the above embodiment, when the first shell and the second shell are connected and matched, the first shell and the second shell gradually approach each other, so that the pushing member can approach the protective cover and open the protective cover. During this process, there is no need to control the movement of the protective cover through additional operations, which is conducive to simplifying the connection operation of the first split and the second split.

[0009] In some embodiments of the present application, the pusher is movably disposed on the second housing and is configured to move to a third position. When the pusher moves to the third position and the first and second housings are connected and mated, the pusher abuts the protective cover to move the protective cover to the second position. The second split body also includes a control member. The control member is connected to the pusher and configured to drive the pusher to move.

[0010] In the above embodiment, the relative position of the pushing member is controlled by the control member so that the pushing member can be moved to the third position to open the protective cover when needed, and the pushing member can be moved to other positions when the pushing member is not needed to push the protective cover, which is beneficial to avoid affecting or obstructing other structures.

[0011] In some embodiments of the present application, the first housing is provided with a relief groove. When the protective cover is in the first position, a portion of the protective cover is located within the relief groove. When the first and second housings are connected and mated, a pusher is inserted into the relief groove and pushes the protective cover to the second position. When the first and second housings are separated, the pusher is higher than the second terminal in the direction from the second housing toward the first housing.

[0012] In the above embodiment, when the pusher pushes the protective cover, it can extend into the avoidance groove, which not only helps to hide the pusher but also allows the second housing to share the force from the first split body. Furthermore, the pusher is higher than the second terminal. Therefore, when the first and second housings are connected, the pusher contacts the protective cover before the second terminal, thereby pushing the protective cover to the second position before the second terminal connects with the first terminal. This reduces the possibility of damage to the second terminal due to impact with the protective cover.

[0013] In some embodiments of the present application, at least one of the pusher and the protective cover is provided with an inclined surface. The inclined surface is inclined relative to the second housing and toward the first housing. The inclined surface is configured such that, when the first and second split bodies are connected and mated, the pusher and the protective cover abut against each other via the inclined surface, thereby pushing the protective cover to the second position.

[0014] In the above embodiment, when the first shell and the second shell are close to each other, the pushing member and the second terminal both move close to the first shell, and the pushing member and the protective cover are pushed together by the inclined surface to change the direction of the force exerted by the pushing member on the protective cover, which is conducive to making the moving path of the protective cover to the second position as perpendicular as possible to the connection path between the first terminal and the second terminal, thereby improving the moving speed of the protective cover to avoid the connection path between the first terminal and the second terminal.

[0015] In some embodiments of the present application, on a projection surface of the second housing facing the first housing, the pushing member is disposed around the second terminal.

[0016] In the above embodiment, the pushing member is disposed around the circumference of the second terminal, thereby protecting the second terminal without affecting the connection between the second terminal and the first terminal.

[0017] In some embodiments of the present application, the first split body further includes an elastic member connected to the protective cover and configured to provide an elastic force to move the protective cover to the first position.

[0018] In the above embodiment, the elastic member can drive the protective cover to move to the first position, so that when the first shell and the second shell are separated, the protective cover automatically covers the first terminal, simplifying the separation operation of the first split body and the second split body.

[0019] In some embodiments of the present application, the first terminal has multiple connection locations. The protective cover is provided with multiple avoidance openings. When the protective cover is in the first position, the protective cover shields each connection location. When the protective cover is in the second position, each connection location is exposed to the external environment of the first housing through a avoidance opening.

[0020] In the above embodiment, when the protective cover is in the second position, the structure outside the avoidance opening of the protective cover can still shield the structure outside the connection between the first terminal and the second terminal, thereby improving the protective effect of the protective cover.

[0021] In some embodiments of the present application, the first housing has an assembly wall. The assembly wall is disposed opposite the second housing. A receiving portion is provided on a side of the assembly wall facing away from the second housing. The first terminal is disposed in the receiving portion. A communication port is provided on the assembly wall. The second terminal is connected to the first terminal through the communication port. A receiving groove is provided on a side of the assembly wall facing the second housing. A protective cover is disposed in the receiving groove. When the protective cover is in the first position, the protective cover shields the communication port.

[0022] In the above embodiment, when the protective cover is in the first position, it shields the communication port to protect the first terminal. When in the second position, the protective cover clears the communication port to facilitate connection between the first and second terminals. Furthermore, the protective cover is located on the side of the assembly wall facing the second housing, making it easy to confirm the position of the protective cover and facilitating assembly, maintenance, or replacement of the protective cover without opening the second housing.

[0023] In some embodiments of the present application, the first housing has an assembly wall. The assembly wall is disposed opposite the second housing. A receiving portion is provided on a side of the assembly wall facing away from the second housing. The first terminal is disposed in the receiving portion. The assembly wall has a connecting opening. The second terminal is connected to the first terminal through the connecting opening. A protective cover is disposed in the receiving portion and is located between the receiving portion and the first terminal. When the protective cover is in the first position, the protective cover shields the connecting opening.

[0024] In the above embodiment, when the protective cover is in the first position, it can shield the communication port to protect the first terminal. When in the second position, the protective cover can clear the communication port to facilitate connection between the first and second terminals. Furthermore, the protective cover is located on the side of the mounting wall facing away from the second housing, allowing the protective cover to be protected by the first housing. This improves the accuracy of the protective cover's movement and enhances the protection of the first terminal.

[0025] In some embodiments of the present application, the first housing is provided with a first fastener and a first lock. The second housing is provided with a second fastener and a second lock. The first fastener is configured to align and engage with the second fastener to allow the first housing and the second housing to be detachably connected. The first lock is configured to lock with the second lock and constrain the separation of the first fastener and the second fastener to ensure a fixed connection between the first housing and the second housing. The first lock is also configured to release the lock with the second lock and release the constraints on the first fastener and the second fastener to restore the first housing and the second housing to a detachably connected state.

[0026] In the above embodiment, during the assembly process of the first shell and the second shell, the first fastener and the second fastener are fastened with each other to enable the first shell and the second shell to be initially aligned and movably connected, so as to facilitate subsequent more accurate alignment and locking connection; the first locking member and the second locking member are locked with each other to enable the first split and the second split to be aligned and connected for the second time, thereby improving the accuracy of the relative position of the first shell and the second shell and the connection stability, so as to facilitate the stably aligned and stably connected first terminal and the second terminal.

[0048] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0050] Furthermore, the terms "first," "second," "third," etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0051] In recent years, energy storage power supplies have become increasingly popular in scenarios such as camping, outdoor work, and home backup. Existing energy storage power supplies often have split designs, such as a separate main unit and separate power pack forming a scalable power supply, or a separate inverter and separate battery pack forming a single power supply. The two components are electrically connected via male and female terminals. When separated, the female terminals are exposed to the outside world, making them susceptible to contamination and unsuitable for reuse.

[0052] In the related art, a protective structure is provided on the host to protect the female terminal. However, when the two parts are connected, the protective structure needs to be removed first and then the two parts are connected. This operation is rather cumbersome, resulting in poor product usability.

[0053] An embodiment of the present application provides an energy storage device. The energy storage device includes a first split body and a second split body. The first split body includes a first shell and a first terminal provided on the first shell. The second split body includes a second shell and a second terminal provided on the second shell. The first split body also includes a protective cover. The protective cover is movably provided on the first shell and is configured to be able to move to a first position or a second position. When the first shell and the second shell are separated, the protective cover is in the first position and shields the first terminal from exposing one end of the first shell. When the first shell and the second shell are connected and matched, the protective cover is configured to be able to move to the second position under the action of external force to avoid the connection path between the first terminal and the second terminal.

[0054] When the first and second housings are separated, the protective cover can shield the first terminal, isolating the first terminal from the external environment of the first housing, thereby protecting the first terminal from contamination by the external environment. Furthermore, the protective cover can move relative to the first housing. By moving when the first and second housings are connected, the protective cover avoids the connection path between the first and second terminals, allowing the first and second terminals to be connected. This eliminates the need to disassemble the protective structure for the first terminal, thereby simplifying the assembly steps of the first and second sub-bodies. Furthermore, it helps to extend the time the protective cover protects the first terminal, thereby enhancing the protective effect of the first terminal.

[0055] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features of the embodiments may be combined with each other.

[0056] See also Figure 1 One embodiment of the present application provides an energy storage device 100. The energy storage device 100 includes a first body 10 and a second body 20. The first body 10 and the second body 20 cooperate with each other.

[0057] In some embodiments, one of the first split 10 and the second split 20 is an independent host, and the other is an independent power pack, and the energy storage device 100 as a whole forms a design of a capacity-expandable power supply. In some embodiments, one of the first split 10 and the second split 20 is an independent inverter, and the other is an independent battery pack, and the energy storage device 100 as a whole forms a design of a power supply. In some embodiments, one of the first split 10 and the second split 20 is an independent power pack, and the other is also an independent power pack, and the energy storage device 100 as a whole forms a design of a large-capacity power pack. Among them, the host has both an inverter module and a battery module, which can output AC power, and thus can independently supply power to electrical devices; while the power pack only has a battery module, which can only output DC power and cannot independently supply power to electrical devices. It needs to be powered by a device with an inverter module to supply power to the electrical devices, and is therefore usually used as a power expansion device for devices such as the host.

[0058] In some embodiments, the first body 10 and the second body 20 can be separated from each other or assembled to be connected to each other. In some embodiments, the first body 10 is stacked on the second body 20 along the direction of gravity. In other embodiments, the first body 10 can be placed side by side with the second body 20 in a direction perpendicular to the direction of gravity. For example, Figure 1 As shown in FIG, the first split body 10 is assembled to the upper side of the second split body 20 along the direction of gravity.

[0059] See also Figure 2 、 Figure 4 and Figure 6 In some embodiments, the first split body 10 includes a first housing 11 and a first terminal 12 provided on the first housing 11. The second split body 20 includes a second housing 21 and a second terminal 22 provided on the second housing 21. The first housing 11 is configured to be connectable to the second housing 21. When the first housing 11 and the second housing 21 are connected, the first terminal 12 and the second terminal 22 are connected. The first split body 10 and the second split body 20 can also establish an electrical connection when they are mechanically connected.

[0060] See also Figure 2 、 Figure 4 and Figure 6 In some embodiments, the first split body 10 further includes a protective cover 13. The protective cover 13 is movably provided on the first housing 11 and is configured to be movable to a first position or a second position relative to the first housing 11. When the first housing 11 and the second housing 21 are separated, the protective cover 13 is in the first position and shields the end of the first terminal 12 that is exposed from the first housing 11. When the first housing 11 and the second housing 21 are connected and mated, the protective cover 13 is configured to be movable to the second position under the action of an external force to avoid an empty connection path between the first terminal 12 and the second terminal 22. Figure 2 The protective cover 13 of one form of energy storage device 100 is moved to a first position. Figure 3 The figure shows another form of the energy storage device 100 in which the protective cover 13 moves to the second position. Figure 8 for Figure 2 An enlarged view of a portion of the structure of the energy storage device 100 shown in the form of FIG. Figure 8 The protective cover 100 is in the first position; Figure 9 for Figure 2 An enlarged view of a portion of the energy storage device 100 of the illustrated form, with the protective cover 100 in the second position.

[0061] When the first shell 11 and the second shell 21 are separated, the protective cover 13 can shield the first terminal 12, separating the first terminal 12 from the external environment of the first shell 11, which is beneficial to protecting the first terminal 12 from contamination by the external environment. In addition, the protective cover 13 can move relative to the first shell 11. The protective cover 13 moves when the first shell 11 and the second shell 21 are connected and matched, and avoids the connection path between the first terminal 12 and the second terminal 22 when the first shell 11 and the second shell 21 are connected, so as to allow the first terminal 12 and the second terminal 22 to be connected. On the one hand, there is no need to disassemble the protective structure for the first terminal 12, thereby simplifying the assembly steps of the first split body 10 and the second split body 20. On the other hand, it is beneficial to extend the time that the protective cover 13 protects the first terminal 12, thereby improving the protective effect of the first terminal 12.

[0062] See also Figure 2 、 Figure 3 、 Figure 6 and Figure 7 In some embodiments, the second split body 20 further includes a pusher 23. The pusher 23 is disposed on the second housing 21. When the first housing 11 and the second housing 21 are connected and mated, the pusher 23 abuts against the protective cover 13 to move the protective cover 13 to the second position.

[0063] When the first shell 11 and the second shell 21 are connected and matched, the first shell 11 and the second shell 21 gradually approach each other, so that the pushing member 23 can approach the protective cover 13 and open the protective cover 13. During this process, there is no need to control the movement of the protective cover 13 through additional operations, which is conducive to simplifying the connection operation of the first split 10 and the second split 20.

[0064] In some embodiments, the pusher 23 can be omitted. When the first housing 11 and the second housing 21 are connected and mated, the second terminal 22 abuts the protective cover 13 to move the protective cover 13 to the second position. In some embodiments, the first split body 10 further includes a linkage member (not shown) connected to the protective cover 13. The linkage member is configured to move in response to an external force to drive the protective cover 13 to move to the first position or the second position.

[0065] See also Figure 6 and Figure 7 In some embodiments, the pusher 23 is fixed to the second housing 21 to facilitate accurate and stable movement of the protective cover 13 .

[0066] In some embodiments, the pushing member 23 is movably provided in the second shell 21 and is configured to be able to move to a third position relative to the second shell 21. When the pushing member 23 moves to the third position and the first shell 11 and the second shell 21 are connected and matched, the pushing member 23 abuts the protective cover 13 to move the protective cover 13 to the second position. The second split 20 also includes a control member (not shown). The control member is connected to the pushing member 23 and is configured to drive the pushing member 23 to move. Exemplarily, the pushing member 23 can move to a position hidden in the second shell 21 or a third position. It can be understood that in some embodiments, the position of the pushing member 23 when it is fixed is the third position; exemplarily, Figure 6 and Figure 7 The push member 23 is shown to be fixedly arranged and is in a third position relative to the second housing 21 .

[0067] The relative position of the push member 23 is controlled by the control member so that the push member 23 can be moved to the third position to open the protective cover 13 when needed, and the push member 23 can be moved to other positions when the push member 23 is not needed to push the protective cover 13, which helps to avoid affecting or obstructing other structures.

[0068] In some embodiments, the control member drives the push member 23 to move to the third position, and drives the push member 23 to leave the third position. In some embodiments, the second split body 20 further includes a reset member (not shown), which is configured to apply a force to the push member 23 to leave the third position. That is, under the action of an external force, the control member drives the push member 23 to move to the third position; after the external force is removed, the reset member drives the push member 23 to leave the third position. Exemplarily, the reset member can be a structure that can produce elastic deformation, such as an elastic arm that can bend under force.

[0069] See also Figure 2 、 Figure 4 and Figure 6 In some embodiments, the first shell 11 is provided with a avoidance groove 1111. When the protective cover 13 is in the first position, part of the protective cover 13 is located in the avoidance groove 1111. When the first shell 11 and the second shell 21 are connected and matched, the pushing member 23 is inserted into the avoidance groove 1111 and pushes the protective cover 13 to the second position. When the first shell 11 and the second shell 21 are separated, along the direction of the second shell 21 toward the first shell 11, the pushing member 23 is higher than the second terminal 22. In some embodiments, if the pushing member 23 is movably provided, the pushing member 23 is higher than the second terminal 22 when it moves to the third position.

[0070] When the pusher 23 pushes the protective cover 13, it can extend into the avoidance groove 1111, which not only helps to hide the pusher 23, but also helps the second housing 21 share the force from the first split body 10. In addition, the pusher 23 is higher than the second terminal 22. Therefore, when the first housing 11 and the second housing 21 are connected and mated, the pusher 23 contacts the protective cover 13 before the second terminal 22, thereby first pushing the protective cover 13 to the second position, and then the second terminal 22 is connected and mated with the first terminal 12, thereby reducing the possibility of the second terminal 22 being damaged by impacting the protective cover 13.

[0071] See also Figure 2 、 Figure 4 and Figure 6 In some embodiments, at least one of the pusher 23 and the protective cover 13 is provided with an inclined surface 131 (the inclined surface 131 of the pusher 23 is not shown). The inclined surface 131 is inclined relative to the second housing 21 toward the first housing 11. The inclined surface 131 is configured such that when the first and second split bodies 10 and 20 are connected and mated, the pusher 23 and the protective cover 13 abut against each other via the inclined surface 131, thereby pushing the protective cover 13 to the second position. For example, the inclined surface 131 can be a flat surface or a curved surface.

[0072] When the first shell 11 and the second shell 21 are close to each other, the pushing member 23 and the second terminal 22 both move close to the first shell 11, and the pushing member 23 and the protective cover 13 are pushed and matched by the inclined surface 131 to change the direction of the force exerted by the pushing member 23 on the protective cover 13, which is conducive to making the moving path of the protective cover 13 to the second position as perpendicular as possible to the connection path of the first terminal 12 and the second terminal 22, thereby increasing the moving speed of the protective cover 13 to avoid the connection path of the first terminal 12 and the second terminal 22.

[0073] See also Figure 3 and Figure 7 In some embodiments, the pusher 23 surrounds the second terminal 22 on the projection surface of the second housing 21 toward the first housing 11. It is understood that in some embodiments, the pusher 23 is continuously surrounded, or the pusher 23 can also be spaced and surrounded.

[0074] The pushing member 23 is disposed around the circumference of the second terminal 22 to protect the second terminal 22 without affecting the connection between the second terminal 22 and the first terminal 12 .

[0075] See also Figure 2 、 Figure 4 and Figure 6 In some embodiments, the first split body 10 further includes an elastic member 14. The elastic member 14 is connected to the protective cover 13 and is configured to provide an elastic force to move the protective cover 13 to the first position. For example, the elastic member 14 may be a spring, a tension spring, or a structure on the first housing 11 that can produce elastic deformation. The structure on the first housing 11 that can produce elastic deformation may be an elastic arm that bends under force.

[0076] The elastic member 14 can drive the protective cover 13 to move to the first position, so that when the first housing 11 and the second housing 21 are separated, the protective cover 13 automatically covers the first terminal 12 , simplifying the separation operation of the first split body 10 and the second split body 20 .

[0077] See also Figure 4 and Figure 5 In some embodiments, the first terminal 12 has a plurality of connection locations 121. When the protective cover 13 is in the first position, the protective cover 13 shields each connection location 121. The protective cover 13 has a position-avoiding opening 132. When the protective cover 13 is in the second position, the connection locations 121 are exposed to the external environment of the first housing 11 through the position-avoiding opening 132.

[0078] See also Figure 3 and Figure 5 In some embodiments, a plurality of the avoidance openings 132 are provided. When the protective cover 13 is located at the second position, each connection position 121 is exposed to the external environment of the first housing 11 through one avoidance opening 132 .

[0079] When the protective cover 13 is in the second position, the structure outside the avoidance opening 132 of the protective cover 13 can still shield the structure outside the connection between the first terminal 12 and the second terminal 22 , thereby improving the protective effect of the protective cover 13 .

[0080] See also Figure 2 and Figure 4 In some embodiments, when the protective cover 13 is located at the second position, the plurality of connection positions 121 are exposed to the external environment of the first shell 11 through a position-avoiding opening 132 .

[0081] When the protective cover 13 is in the second position, the avoidance opening 132 can avoid multiple connection positions 121 at the same time, thereby increasing the area of ​​the connection path between the first terminal 12 and the second terminal 22 that the avoidance opening 132 can avoid, thereby reducing the avoidance error rate.

[0082] See also Figure 4 and Figure 5 In some embodiments, the first housing 11 has a mounting wall 111. The mounting wall 111 is disposed opposite the second housing 21. A receiving portion 1112 is provided on a side of the mounting wall 111 facing away from the second housing 21. The first terminal 12 is disposed in the receiving portion 1112. The mounting wall 111 has a connecting opening 1113. The second terminal 22 is connected to the first terminal 12 through the connecting opening 1113. When the protective cover 13 is in the first position, the protective cover 13 shields the connecting opening 1113.
