Description

Technical Field

[0001] The present invention relates to the technical field of energy storage devices, and in particular to an energy storage power supply. Background Art

[0002] With the popularization of electric vehicles, the corresponding charging stations / charging piles have also been popularized. However, there are no corresponding charging stations in some remote areas. When the electric vehicle runs out of power, it cannot move. At this time, some mobile charging stations are needed to charge the electric vehicle. However, in order to ensure the safety of charging, some electric vehicle brands require the charging station to be grounded before charging the electric vehicle. At present, most mobile charging stations or energy storage power supplies do not have a grounding function considering mobility.

[0003] To achieve the grounding function, it is necessary to connect the grounding electrode of the energy storage power supply to the ground through a conductive member. Currently, the common methods are to ground through the outer shell or through an independent grounding accessory. If grounded through the outer shell, the direct contact between the outer shell and the ground reduces the comfort of product use, while grounding through an independent grounding accessory will make the product structure too complex. Summary of the Invention

[0004] The object of the present invention is to provide an energy storage power supply that can be stably grounded, has a simple structure, and high use comfort.

[0005] To achieve the above technical effects, the technical solution of the energy storage power supply of the present invention is as follows:

[0006] The present invention discloses an energy storage power supply, including: a housing; a gasket that abuts against the bottom wall of the housing; a grounding member that penetrates through the gasket and is electrically connected to the energy storage power supply; wherein: the gasket has a natural state and a deformed state. In the natural state, one end of the grounding member extending out of the housing retracts into the gasket; in the deformed state, one end of the grounding member extending out of the housing exposes the gasket.

[0007] In some embodiments, a deformation groove is provided on the gasket.

[0008] In some specific embodiments, the deformation groove is located on the top wall of the gasket, and the bottom wall of the gasket has an arc surface.

[0009] In some specific embodiments, the deformation groove is located on the peripheral wall of the gasket, and the deformation grooves are multiple and are arranged at intervals along the height direction of the gasket.

[0010] In some embodiments, the energy storage power supply further includes a conductive member, which is arranged in the housing, is connected to the grounding member, and is electrically connected to the electrode of the energy storage power supply.

[0011] In some specific embodiments, a first through hole is provided on the gasket, a second through hole is provided on the conductive member, and the grounding member is inserted into the first through hole and the second through hole.

[0012] In some more specific embodiments, the grounding member has a mating section and a connecting section. The diameter of the connecting section is smaller than that of the mating section. The mating section is inserted into the first through hole and abuts against the bottom wall of the housing, and the connecting section is inserted into the second through hole.

[0013] In some specific embodiments, a receiving portion is provided in the housing, and the receiving portion defines a first receiving groove, and the conductive member is fitted in the first receiving groove.

[0014] In some more specific embodiments, a second receiving groove is provided on the conductive member, and the second receiving groove penetrates through the conductive member in the length direction; a clamping convex edge is provided on the top wall of the first receiving groove, and the clamping convex edge is fitted in the second receiving groove and abuts against the side wall of the second receiving groove; and / or two spaced abutting convex edges are provided on the bottom wall of the first receiving groove, and the abutting convex edges are used to support the conductive member, and the conductive member is clamped between the clamping convex edge and the abutting convex edge.

[0015] In some more specific embodiments, the housing includes a front housing and a rear housing that are connected to each other. One end of the front housing and the rear housing is open, and the other end is closed. The open end of the front housing is butted against the open end of the rear housing. The receiving portion, the first receiving groove, the clamping convex edge and the abutting convex edge are all provided on the front housing and the rear housing, wherein: one end of the abutting convex edge facing the open ends of the front housing and the rear housing has an inclined surface.

[0016] The beneficial effects of the energy storage power supply of the present invention are as follows: Since a grounding member inserted through the housing is provided in the energy storage power supply, the grounding member can realize the grounding of the entire energy storage power supply, reduce the structural complexity of the entire energy storage power supply, and reduce the manufacturing cost of the energy storage power supply. Since the gasket can be deformed under the action of gravity of the energy storage power supply, one end of the grounding member retracted into the gasket is exposed for grounding. On the premise of ensuring the stable grounding of the energy storage power supply, it can also ensure that the energy storage power supply is placed smoothly on a plane, without damaging the energy storage power supply or the surface of the placement surface, and without generating any noise, improving the use comfort of the energy storage power supply.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "mounted", "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The following refers to Figures 1-4 to describe the specific structure of the energy storage power supply according to the embodiments of the present invention.

[0031] The present invention discloses an energy storage power supply, as Figures 1-4 shown, the energy storage power supply includes a housing 1, a gasket 3 and a grounding member 4. The gasket 3 abuts against the bottom wall of the housing 1. The grounding member 4 is inserted through the gasket 3, and the grounding member 4 is electrically connected to the energy storage power supply; wherein: the gasket 3 has a natural state and a deformed state. In the natural state, one end of the grounding member 4 extending out of the housing 1 retracts into the gasket 3; in the deformed state, one end of the grounding member 4 extending out of the housing 1 exposes out of the gasket 3.

[0032] It can be understood that when the energy storage power supply is placed on a support plane, the gravitational force of the energy storage power supply causes the gasket 3 to deform, so that the gasket 3 in the natural state deforms and switches to the deformed state, that is, one end of the grounding member 4 that retracts into the gasket 3 exposes, so that the grounding member 4 contacts the support plane, realizing the grounding of the energy storage power supply. The grounding of the entire energy storage power supply is achieved by the deformation of the gasket 3 under the gravity of the energy storage power supply. This structure is very simple and reduces the structural complexity of the entire energy storage power supply. At the same time, since the gasket 3 can deform, it can ensure that the energy storage power supply is placed smoothly on the plane, and at the same time, it will not damage the energy storage power supply or the surface of the placement surface, nor generate any noise, improving the use comfort of the energy storage power supply.

[0033] In some embodiments, there are a plurality of gaskets 3, and the plurality of gaskets 3 are spaced apart in the circumferential direction around the housing 1. Thus, there are a plurality of gaskets 3, which further ensures that the energy storage power supply can be placed smoothly on the plane, thereby further avoiding damage to the energy storage power supply or the placement plane and improving the use comfort of the energy storage power supply.

[0034] It should be noted additionally here that in the embodiments of the present invention, the gasket 3 can be selected according to actual needs, and the number, cross-sectional shape, and distribution form of the gasket 3 are not limited herein.

[0035] In some embodiments, as Figures 3-6 shown, a deformation groove 302 is provided on the gasket 3. It can be understood that according to the foregoing, when the energy storage power supply is placed on the support plane, under the action of the gravity of the energy storage power supply, the gasket 3 is deformed, so that one end of the grounding member 4 retracted into the gasket 3 is exposed, thereby enabling the grounding member 4 to contact the support plane and realizing the grounding of the energy storage power supply. In this embodiment, a deformation groove 302 is provided on the gasket 3, and the added deformation groove 302 can make the gasket 3 more easily compressed, so as to ensure that the energy storage power supply can stably compress the gasket 3 to expose one end of the grounding member 4 retracted into the gasket 3.

[0036] In some specific embodiments, as Figure 3 and Figure 4 shown, the deformation groove 302 is located on the top wall of the gasket 3, and the bottom wall of the gasket 3 has an arc surface 303. It can be understood that the bottom wall of the gasket 3 has an arc surface 303, and the deformation groove 302 is located on the top wall of the gasket 3. When an external force acts on the gasket 3, the deformation groove 302 can make the gasket more easily deformed, so that the arc surface 303 is pressed into a plane, thereby ensuring the stability of the energy storage power supply.

[0037] In some specific embodiments, as Figure 5 and Figure 6 shown, the deformation groove 302 is located on the peripheral wall of the gasket 3, and a plurality of deformation grooves 302 are arranged at intervals along the height direction of the gasket 3. It can be understood that the plurality of deformation grooves 302 arranged at intervals along the height direction of the gasket 3 can make the gasket 3 more easily compressed, so as to further ensure that the energy storage power supply can stably compress the gasket 3 to expose one end of the grounding member 4 retracted into the gasket 3.

[0038] In some embodiments, as Figure 1 shown, the energy storage power supply further includes a conductive member 2, the conductive member 2 is arranged in the housing 1, the conductive member 2 is connected to the grounding member 4, and is electrically connected to the electrode of the energy storage power supply. The added conductive member 2 can ensure that the grounding member 4 can be stably connected to the electrode of the energy storage power supply, thereby ensuring that the grounding member 4 can stably realize the grounding of the energy storage power supply.

[0039] In some specific embodiments, as Figure 1As shown, there are two conductive members 2, and the two conductive members 2 are arranged at intervals. A plurality of gaskets 3 are connected to each conductive member 2 at intervals along the length direction of the conductive member 2. It can be understood that a plurality of gaskets 3 are connected to each conductive member 2 at intervals along the length direction of the conductive member 2. Such a distribution form can ensure that the energy storage power supply can be stably grounded, thereby improving the use safety of the energy storage power supply.

[0040] In some embodiments, as Figures 3-6 shown, the gasket 3 is provided with a first through hole 301, and the conductive member 2 is provided with a second through hole 21. The grounding member 4 is inserted into the first through hole 301 and the second through hole 21. It can be understood that the grounding member 4 is inserted into the first through hole 301 and the second through hole 21 to realize the connection between the gasket 3 and the conductive member 2. On the one hand, it ensures the connection stability between the gasket 3 and the conductive member 2, and on the other hand, it ensures the connection stability between the grounding member 4 and the conductive member 2, thereby ensuring the grounding safety of the entire energy storage power supply.

[0041] Here, it is additionally noted that in other embodiments of the present invention, the grounding member 4 can be selected according to actual needs, and the grounding member 4 can be formed into the structural form of other connecting members such as screws, rivets, and pins. Of course, in other embodiments of the present invention, the grounding member 4 can be directly formed on the conductive member 2. After the conductive member 2 is placed inside the housing 1, the grounding member 4 passes through the bottom wall of the housing 1, and the gasket 3 is sleeved on the grounding member 4, thereby completing the connection between the gasket 3 and the conductive member 2. That is to say, in the present invention, the grounding member 4 can be integrally formed with the conductive member 2 or independent of the conductive member 2.

[0042] In some specific embodiments, the grounding member 4 has a mating section 41 and a connecting section 42. The diameter of the connecting section 42 is smaller than that of the mating section 41. The mating section 41 is inserted into the first through hole 301 and abuts against the bottom wall of the housing 1, and the connecting section 42 is inserted into the second through hole 21. It can be understood that the mating section 41 is inserted into the first through hole 301 and abuts against the bottom wall of the housing 1, which can prevent the grounding member 4 from being overly tightened with the second through hole 21, thereby reserving a predetermined deformation margin for the gasket 3 to ensure that the gasket 3 has sufficient deformation margin to hide the grounding member 4 in the natural state.

[0043] In some embodiments, as Figure 2 shown, the housing 1 is provided with a receiving portion 11, and the receiving portion 11 defines a first receiving groove 12. The conductive member 2 is fitted in the first receiving groove 12. It can be understood that the conductive member 2 is installed in the first receiving groove 12, and the first receiving groove 12 can limit the shaking of the conductive member 2 inside the housing 1, ensuring that the conductive member 2 can be stably electrically connected to the electrode of the energy storage power supply, thereby ensuring that the energy storage power supply can be stably grounded.

[0044] In some specific embodiments, asFigure 1 and Figure 2 As shown in Figure 2 , a second receiving groove 22 is provided on the conductive member 2, and the second receiving groove 22 penetrates the conductive member 2 along the length direction; a clamping convex edge 13 is provided on the top wall of the first receiving groove 12, and the clamping convex edge 13 is fitted in the second receiving groove 22 and abuts against the side wall of the second receiving groove 22. It can be understood that when the conductive member 2 is inserted into the first receiving groove 12 along the length direction of the first receiving groove 12, the side wall of the second receiving groove 22 can abut against the clamping convex edge 13. In this way, due to the interaction between the clamping convex edge 13 and the second receiving groove 22, the shaking of the conductive member 2 along its own width direction can be avoided, thereby ensuring that the conductive member 2 can be stably electrically connected to the electrode of the energy storage power supply.

[0045] In some more specific embodiments, as Figure 2 shown, two spaced abutting convex edges 14 are provided on the bottom wall of the first receiving groove 12, and the abutting convex edges 14 are used to support the conductive member 2, and the conductive member 2 is clamped between the clamping convex edge 13 and the abutting convex edge 14. It can be understood that clamping the conductive member 2 between the clamping convex edge 13 and the abutting convex edge 14 can reduce the contact area between the conductive member 2 and the first receiving groove 12 on the premise of ensuring the installation stability of the conductive member 2 and avoiding the shaking of the conductive member 2, thereby facilitating the installation and disassembly of the conductive member 2.

[0046] In some more specific embodiments, as Figure 1 and Figure 2 shown, the housing 1 includes a front housing 101 and a rear housing 102 connected to each other. One end of the front housing 101 and the rear housing 102 is open and the other end is closed. The open end of the front housing 101 is docked with the open end of the rear housing 102. The front housing 101 and the rear housing 102 are both provided with a receiving portion 11, a first receiving groove 12, a clamping convex edge 13 and an abutting convex edge 14. One end of the abutting convex edge 14 facing the open ends of the front housing 101 and the rear housing 102 has an inclined surface 15. It can be understood that the housing 1 including the front housing 101 and the rear housing 102 facilitates the installation and disassembly of the housing 1, thereby facilitating the assembly and disassembly and maintenance of the energy storage power supply. One end of the abutting convex edge 14 facing the open ends of the front housing 101 and the rear housing 102 has an inclined surface 15, and the inclined surface 15 facilitates the two ends of the conductive member 2 to be respectively inserted into the first receiving grooves 12 on the front housing 101 and the rear housing 102, thereby facilitating the installation and disassembly of the conductive member 2.
