[0002] With the rapid development of energy storage technology, the products of energy storage power supplies have become increasingly diversified. An energy storage power supply can be placed outdoors as an independent unit to provide electrical energy for electrical equipment used by people.

[0003] However, when an energy storage power supply is placed outdoors as an independent unit, since it is completely exposed to the external space, the outdoor environment has a huge impact on the use effect of the energy storage power supply. Therefore, how to reduce the influence of the outdoor environment on the energy storage power supply has become an urgent problem to be solved. Summary of the Utility Model

[0004] In view of this, the present application provides a battery housing and a power supply, wherein the battery housing is used to accommodate a battery or a battery pack in the power supply, thereby solving the above technical problems.

[0006] Since the connecting hole provided on the covering part is a connecting blind hole and the connecting blind hole does not penetrate through the covering part, thus, if an external object enters the connecting blind hole, the bottom of the connecting blind hole can prevent the external object from entering the placement cavity along the connecting blind hole. That is, after the covering part is covered on the main housing part, the covering part can isolate the external object outside the placement cavity, improving the sealing effect of the battery housing to prevent the external object from entering the placement cavity and affecting the normal operation of the battery.

[0007] In some embodiments of the first aspect, the main housing part is formed by enclosing a plurality of plate parts, and the joints between the plurality of plate parts are connected by welding.

When the covering part is covered on the main housing part, the connecting edge is connected to the covering edge, thus improving the airtightness of the placement cavity.

[0010] In some embodiments of the first aspect, a seal is further clamped between the main housing portion and the covering portion. When the covering portion covers the main housing portion, the seal is used to fill the gap between the main housing portion and the covering portion, so as to further improve the airtightness of the placement cavity.

[0011] In some embodiments of the first aspect, a pressure regulating hole is provided in the main housing portion and / or the covering portion, and the placement cavity is communicated with the external space of the battery housing through the pressure regulating hole; a pressure regulating valve exposed on the outer surface of the main housing portion is connected to the pressure regulating hole, and the pressure regulating valve is used to control the communication between the pressure regulating hole and the external space of the battery housing. Thus, by opening and closing the pressure regulating valve, the air pressure inside the placement cavity is regulated to ensure the normal operation of the power source.

[0012] In some embodiments of the first aspect, the pressure regulating valve is a breathable and waterproof valve, so as to realize the breathable and waterproof operation of the placement cavity.

[0013] In some embodiments of the first aspect, a first through hole is provided in the main housing portion, a wiring terminal is inserted into the first through hole, and a part of the wiring terminal is exposed on the outer surface of the battery housing; a sealing glue is applied to the periphery of the first through hole to fill the gap between the wiring terminal and the hole wall of the first through hole, so as to improve the airtightness of the battery housing and ensure the working environment of the placement cavity where the battery is located, and prevent the battery from being affected by external objects in the placement cavity and unable to exert its best working effect.

[0014] In some embodiments of the first aspect, a second through hole is provided in the main housing portion, an electronic component is inserted into the second through hole, and a part of the electronic component is exposed on the outer surface of the battery housing; a sealing ring is sleeved on the outer periphery of the electronic component, and the sealing ring covers the gap between the electronic component and the hole wall of the second through hole, thereby ensuring the airtightness of the battery housing.

Specific embodiments

[0028] In order to make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0029] Unless otherwise defined, technical or scientific terms used herein shall have the ordinary meanings as understood by those of ordinary skill in the art to which this application belongs. The use of words such as "a", "an" or "the" in this application does not denote a limitation of quantity, but merely means that there is at least one.

[0030] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0031] Next, in conjunction with the accompanying Figures 1 - 8 drawings in the embodiments of this application,

[0032] please first refer to Figure 1 and Figure 2 . This application provides a power supply 1000, which includes a battery 200 or a battery pack, and a battery housing 100. Among them, the battery housing 100 is used to accommodate a battery 200 or a battery pack, and the battery 200 or the battery pack is placed in the placement cavity 11 of the battery housing 100. Please also refer to Figure 3 , Figure 6 , Figure 7 and Figure 8 . The battery housing 100 includes a main housing part 1 and a covering part 2. The main housing part 1 is formed with a placement cavity 11 and a placement entrance 10, and the battery 200 or the battery pack is placed into the placement cavity 11 through the placement entrance 10; the covering part 2 is hermetically connected to the placement entrance 10 to make the placement cavity 11 in a closed state; the covering part 2 is provided with a connecting blind hole 20 for connecting a handle 9.

[0033] Among them, since the connection hole opened on the covering part 2 is a connecting blind hole 20, through Figure 8It can be seen that the connecting blind hole 20 does not penetrate through the covering part 2. Thus, if foreign objects enter the connecting blind hole 20, the bottom of the connecting blind hole 20 can prevent the foreign objects from entering the placement cavity 11 along the connecting blind hole 20. That is, after the covering part 2 covers the main housing part 1, the covering part 2 can isolate the foreign objects outside the placement cavity 11, improving the sealing effect of the battery housing 100 to prevent foreign objects from entering the placement cavity 11 and affecting the normal operation of the battery 200.

[0034] It should be noted that the battery pack includes multiple batteries 200. In the subsequent embodiments, for the sake of brevity and clarity of the description language, the battery 200 is uniformly used for description in the subsequent process. This battery 200 can represent an independent battery 200 or a battery pack.

[0035] It should also be noted that the reason for blocking foreign objects from entering the space where the battery 200 is located (i.e., the placement cavity 11 independent of the external space of the battery housing 100) is that if dust and moisture in the air enter the placement cavity 11, they will corrode and contaminate the battery 200 and metal parts in the placement cavity 11, thereby affecting the service life and function of the battery 200 and metal parts. Especially for the battery 200, after being interfered by moisture and dust, the battery 200 may overheat during operation or have poor contact with other electrical components. Thus, it not only affects the operation effect of the battery 200 but also causes irreversible damage to the battery 200, further reducing the service life of the battery 200.

[0036] In some embodiments, riveting operation is performed on the covering part 2 to form the connecting blind hole 20; or, the covering part 2 is formed by casting. When casting the covering part 2, a casting mold with a part of the model provided with the connecting blind hole 20 is selected. Thus, the formed covering part 2 will correspondingly form the connecting blind hole 20 to provide a connecting hole for the connecting handle 9.

[0037] Please refer to Figure 2 、 Figure 3 and Figure 6, in some embodiments, the main housing portion 1 is formed by enclosing a plurality of plate portions 12. The joints between the plurality of plate portions 12 are connected by welding. The joints between the plurality of plate portions 12 are connected to each other so that the plurality of plate portions 12 enclose a placement cavity 11. Welding can ensure the connection strength between the plurality of plate portions 12. By performing welding on the joints between the plate portions 12, a sealed connection can be achieved between the plurality of plate portions 12. Thus, when the covering portion 2 covers the main housing portion 1, the placement entrance 10 is blocked by the covering portion 2, and the placement cavity 11 is isolated from the external space of the main housing portion 1. Because of the welded connection between the individual plates, foreign objects will not enter the placement cavity 11 along the joints of the individual plates, thereby improving the airtightness of the placement cavity 11. Thus, the probability of foreign objects entering the placement cavity 11 is reduced, and correspondingly, the situation where the battery 200 is abnormally operated due to foreign object interference is reduced.

[0038] In some embodiments, the welded connection is formed by full laser welding. It should be understood that full laser welding is an advanced welding technology. By controlling a high-power laser beam, precise control of the welding process can be achieved, and deep fusion between the materials to be welded can be realized. Thus, the connection strength between the individual plate portions 12 is improved, and to a certain extent, the airtightness of the placement cavity 11 is improved.

[0039] For reference Figure 2 , in some embodiments, the main housing portion 1 is provided with a connecting edge 13 at the periphery of its placement entrance 10, and the covering portion 2 is provided with a covering edge 21 at its periphery. When the covering portion 2 covers the main housing portion 1, the connecting edge 13 is connected to the covering edge 21. Thus, the connection area between the covering portion 2 and the main housing portion 1 is increased through the connecting edge 13 and the covering edge 21, improving the connection strength between the covering portion 2 and the main housing portion 1, and to a certain extent, improving the airtightness of the placement cavity 11.

[0040] Please refer to Figure 2 and Figure 5 , in some embodiments, a sealing member 3 is further clamped between the main housing portion 1 and the covering portion 2. When the covering portion 2 covers the main housing portion 1, the sealing member 3 is used to fill the gap between the main housing portion 1 and the covering portion 2. Thus, the airtightness of the placement cavity 11 is further improved.

[0041] Among them, in order to improve the sealing effect of the sealing member 3, the sealing member 3 can have a certain elasticity. When the covering portion 2 covers the main housing portion 1, the sealing member 3 can be squeezed to produce a certain amount of compressive deformation. The sealing member 3 has an interference fit with the covering portion 2 and the main housing portion 1, thereby ensuring the filling effect of the sealing member 3 on the gap between the main housing portion 1 and the covering portion 2, and thus improving the airtightness of the placement cavity 11.

[0042] Please refer to together Figure 2 、 Figure 3 and Figure 6, in some embodiments, the main housing portion 1 and / or the covering portion 2 are provided with a pressure regulating hole 121, and the placement cavity 11 is communicated with the external space of the battery housing 100 through the pressure regulating hole 121; a pressure regulating valve 4 exposed on the outer surface of the main housing portion 1 is connected to the pressure regulating hole 121, and the pressure regulating valve 4 is used to control the communication between the pressure regulating hole 121 and the external space of the battery housing 100.

[0043] Specifically, when the power supply 1000 operates, the battery 200 will generate heat. Since the placement cavity 11 is in a closed state, the gas inside the placement cavity 11 will expand due to heat, resulting in an increase in the air pressure inside the placement cavity 11 and being higher than the air pressure outside the placement cavity 11. If the air pressure inside the placement cavity 11 is not adjusted in time, the surfaces of the battery housing 100 will deform under the action of the air pressure, and even the connection relationship between the plates or between the main housing portion 1 and the covering portion 2 will be released, resulting in the placement cavity 11 no longer having airtightness. In the above embodiments, by providing the pressure regulating hole 121 in the main housing portion 1 and / or the covering portion 2 and correspondingly connecting the pressure regulating valve 4, the opening and closing of the pressure regulating valve 4 are used to regulate the air pressure inside the placement cavity 11 to ensure the normal operation of the power supply 1000.

[0044] In some embodiments, the pressure regulating valve 4 is a breathable waterproof valve. It should be noted that a filter membrane made of polymer PE material is laid on the valve port of the waterproof breathable valve. Since the polymer PE material has the property of being breathable but not permeable to water, the breathable waterproof valve using the filter membrane made of polymer PE material can have the ability of being breathable but not permeable to water, and the breathable waterproof valve is an active valve and can automatically participate in the pressure relief operation process of the power supply 1000 without the user having to perform additional start or close actions. In this way, the breathable and waterproof operation of the placement cavity 11 is realized, while ensuring the air pressure in the placement cavity 11, the cleanliness and dryness of the environment in the placement cavity 11 can also be ensured.

[0045] In some other embodiments, the pressure regulating valve 4 is a one-way valve. In this way, when the pressure regulating valve 4 is opened, the high-pressure gas inside the placement cavity 11 is discharged through the pressure regulating valve 4, and the external gas will not enter the placement cavity 11 due to the decrease in the internal air pressure. Thus, foreign matters such as dust and water vapor in the external gas will not enter the placement cavity 11 through the pressure regulating valve 4, and will not cause adverse effects such as corrosion and pollution to the battery 200 and metal parts in the placement cavity 11. That is, the cleanliness and dryness of the operating environment of the battery 200 are ensured, and the service life and operating effect of the battery 200 are extended.

[0046] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6, in some embodiments, the main housing portion 1 is provided with a first through hole 122, and a wiring terminal 5 is inserted into the first through hole 122, and a part of the wiring terminal 5 is exposed on the outer surface of the battery housing 100; a sealing glue 6 is coated on the periphery of the first through hole 122 to fill the gap between the wiring terminal 5 and the hole wall of the first through hole 122.

[0047] It should be noted that since the wiring terminal 5 needs to pass through wires, the hole portion for connecting the wiring terminal 5 must be a through hole (in the above embodiments, this through hole is the above-mentioned first through hole 122). In this way, the connecting wire located in the placement cavity 11 can extend out of the battery housing 100 and connect to an external electrical device, so that the wiring terminal 5 can exert its electrical connection effect.

[0048] Since the first through hole 122 penetrates the main housing portion 1, foreign objects may enter the placement cavity 11 along the connection gap between the wiring terminal 5 and the first through hole 122, thereby contaminating the placement cavity 11 and affecting the normal operation of the battery 200. Therefore, to avoid such a situation, a sealing glue 6 is convexly provided on the periphery of the first through hole 122 (as Figure 1 shown). In this way, the sealing glue 6 can fill the connection gap between the wiring terminal 5 and the first through hole 122, improving the airtightness of the battery housing 100 to ensure the operating environment of the placement cavity 11 where the battery 200 is located, and avoiding the battery 200 from not being able to exert its best operating effect due to foreign object intrusion in the placement cavity 11.

[0049] Please continue to refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , in some embodiments, the main housing portion 1 is provided with a second through hole 123, and an electronic component 7 is inserted into the second through hole 123, and a part of the electronic component 7 is exposed on the outer surface of the battery housing 100; a sealing ring 8 is sleeved on the outer periphery of the electronic component 7, and the sealing ring 8 covers the gap between the electronic component 7 and the hole wall of the second through hole 123.

[0050] It should be noted that when the user uses the power supply 1000 to supply electrical energy to the electrical device, the electrical device needs to establish an electrical connection relationship with the battery 200 located in the placement cavity 11 through the electronic component 7, so as to use the electrical device. Therefore, the electronic component 7 also needs to be connected to the battery housing 100 through a through hole structure. In this way, the electronic component 7 can connect to the electronic device located outside the battery housing 100 and can also connect to the battery 200 located in the placement cavity 11, enabling the electronic component 7 to play its own role.

[0051] In the above embodiments, since the electronic component 7 is inserted into the second through hole 123, foreign objects may enter the placement cavity 11 along the installation gap between the electronic component 7 and the second through hole 123, thereby contaminating the working environment of the battery 200. Therefore, a sealing ring 8 is sleeved on the outer periphery of the electronic component 7 to block the gap formed between the electronic component 7 and the second through hole 123, thereby ensuring the airtightness of the battery housing 100.

[0052] Furthermore, the sealing ring 8 can be configured to fit the shape of the electronic component 7, so that while covering the installation gap between the electronic component 7 and the second through hole 123, it can also block the insertion interface of the electronic component 7 to prevent water and dust from entering the insertion interface and affecting the power-on effect between the external device and the electronic component 7.

[0053] Among them, the electronic component 7 can be a USB connector, a Powercon connector, a heavy-duty connector, a CPC, a general MATE-N-LOK connector, etc., so that the power supply can be adapted to connect a variety of electronic devices.

[0054] It should be noted that for the foregoing method embodiments, for the sake of simple description, they are all expressed as a series of action combinations. However, those skilled in the art should know that this application is not limited by the described action sequence, because according to this application, certain steps can be performed in other sequences or simultaneously. Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily essential to this application.

[0055] In the above embodiments, the descriptions of the respective embodiments have their own emphases. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0056] As described above, the above embodiments are only used to illustrate the technical solutions of this application, rather than to limit it; although this application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of this application.
