Description

Technical Field

[0001] The present invention belongs to the technical field of power supply casings, and specifically relates to a portable waterproof energy storage power supply casing. Background Art

[0002] In the current structural design of household energy storage batteries, plastic handles are usually fixed with simple nuts and screws for easy transportation. Although this design is easy to install, its waterproof performance can only meet the IP54 standard and is difficult to resist rain in severe weather conditions. To address this problem, an improved handle structure has emerged, which is to weld the sheet metal handle and the bottom shell into one to achieve a higher level of waterproof performance, such as IP65 or IP66. However, although this integrated design improves the waterproof performance, it also brings new problems: once the handle is damaged or broken, the carrying function of the entire battery will be affected, and due to the integration of the handle and the bottom shell, the handle cannot be replaced separately for continued use.

[0003] Therefore, the handles on the existing energy storage battery casings have the following defects: (1) The plastic handle design can only meet the basic water-proof requirements, and the waterproof effect is poor, which may cause the battery to be damaged by rain. (2) Although the integrated sheet metal handle design improves the waterproof performance, once the handle is damaged, it cannot be replaced separately, which affects the continuous use and maintenance of the battery. Utility Model Content

[0004] The purpose of this scheme is to provide a portable waterproof energy storage power supply casing to solve the problem that the existing battery casing handle has poor waterproof effect and is difficult to replace.

[0005] In order to achieve the above object, the present invention provides a portable waterproof energy storage power supply housing, including a power supply housing, and further comprising:

[0006] A welding base plate, the welding base plate is welded to the top of the power supply housing, and the welding base plate is provided with blind hole pressure riveting nut columns;

[0007] The handle is provided with a blind hole matched with the blind hole rivet nut column, a bolt is arranged in the blind hole, and the bolt is threadedly connected with the blind hole rivet nut column.

[0008] The principle of this solution is that by welding a bottom plate on the top of the power supply housing, there is no gap between the welded bottom plate and the power supply housing, thereby preventing rainwater from seeping in. The welded bottom plate serves as a base, and the handle is threadedly connected to the blind hole rivet nut column of the welded bottom plate by bolts to fix the handle.

[0009] The effects of this solution are as follows: (1) The blind hole rivet nut column can not only connect the bolts to fix the handle, but also prevent rainwater from entering the welded base plate through the bolt threads after the bolts are loosened. (2) The blind hole rivet nut column allows the nut column to be fixed in the welded base plate without penetrating the base plate, thereby maintaining the sealing between the welded base plate and the power supply housing. (3) The welding of the welded base plate and the power supply housing prevents the infiltration of rainwater. The handle and the welded base plate are detachably connected by the bolt threads, making it easy to replace the handle after damage.

[0010] Furthermore, the four sides of the welding base plate are provided with raised edges, and the height of one edge is higher than that of the other three edges.

[0011] The principle and effect of this solution are: to facilitate the fixing and welding of the welding base plate when installing it.

[0012] Furthermore, the handle is a spring handle.

[0013] The principle and effect of this solution are that the spring handle can automatically return to its original position after being pressed or folded, so that the handle can be compactly attached to the surface of the welding base plate when not in use, saving space.

[0014] Furthermore, a boss is provided on the blind hole.

[0015] The principle and effect of this solution are as follows: since this device is mainly suitable for indoor household energy storage and outdoor use with eaves, and the existing household energy storage use scenarios are basically installed outdoors and on walls, rainwater can easily penetrate into the power supply casing in heavy rain weather. Therefore, a boss is set to make the height of the bolt hole higher than the height of the blind hole to prevent rainwater from flowing into the blind hole.

[0016] Furthermore, a waterproof rubber ring is provided inside the boss.

[0017] The principle and effect of this solution are: the waterproof rubber ring increases the sealing between the boss and the bolt to prevent rainwater from entering.

[0018] Furthermore, a first contact is provided on the boss, a second contact matching the first contact is provided on the bolt, an indicator light is provided on the handle, the indicator light is electrically connected to the first contact, the indicator light is normally open, and the indicator light goes out after the first contact contacts the second contact.

[0019] The principle and effect of this scheme are as follows: (1) Since the device is easily vibrated during transportation, the bolts are prone to gradually loosen, causing rainwater to penetrate into the bolts and blind hole rivet nut columns and cause corrosion. At the same time, when the bolts are screwed into the blind hole rivet nut columns, the bolts may not be screwed to the appropriate position, causing the bolts to loosen easily, and the bolts may be screwed in when they are misaligned and stripped, causing vibration and loosening in the later stage. Therefore, the first contact and the second contact are set to detect the screwing of the bolts. (2) When the bolts are screwed into the blind hole rivet nut columns, the second contact on the bolts will contact the first contact, thereby disconnecting the indicator light circuit. At this time, it means that the bolts have been screwed to the appropriate position. At the same time, if the bolts are misaligned and stripped, the second contact on the bolts is in an inclined state and will not contact the first contact. Therefore, when the indicator light is off, it can also be used to detect whether the bolts are misaligned and stripped. (3) When the bolts are loosened by vibration, the second contact will move away from the first contact, causing the indicator light to light up again, thereby reminding the user that the bolts are loose.

[0028] The following will clearly and completely describe the concept and technical effects of the utility model in combination with the embodiments, so as to fully understand the purpose, features and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model:

[0029] Embodiment 1:

[0030] See also Figure 1-Figure 5 A portable waterproof energy storage power supply housing comprises a power supply housing 1, a mobile power supply is arranged in the power supply housing 1, a welding base plate 2 is welded on the top of the power supply housing 1, four blind hole pressure rivet nut columns 21 are welded on the welding base plate 2, and a raised edge 22 is arranged on the four sides of the welding base plate 2, wherein the height of one edge 22 is higher than the other three sides, such as Figure 3 and Figure 4 As shown, the sheet metal on the left side of the welding bottom plate 2 needs to be lengthened by 1mm to facilitate the fixing and welding of the welding bottom plate 2 when it is installed. At the same time, the welding bottom plate 2 needs to be fully welded on all four edges to prevent water from rushing into the power supply housing 1 from the four corners during the water immersion test, causing water to intrude into the electrical appliance and cause damage. By welding the bottom plate 2 on the top of the power supply housing 1, there is no gap between the welding bottom plate 2 and the power supply housing 1, thereby preventing rainwater from seeping in.

[0031] The handle 3 is a spring handle, and a blind hole 31 is provided on the handle 3 to match the blind hole rivet nut column 21. A bolt 32 is passed through the blind hole 31, and the bolt 32 is threadedly connected with the blind hole rivet nut column 21. The blind hole rivet nut column 21 can be connected with the bolt 32 to fix the handle 3, and can also prevent rainwater from entering the welding base plate 2 through the thread of the bolt 32 after the bolt 32 is loosened.

[0032] Since the device is mainly suitable for indoor household energy storage and outdoor use with eaves, and the existing household energy storage use scenarios are basically installed outdoors and on walls, rainwater can easily penetrate into the power supply housing in rainy weather. Therefore, a boss 33 is provided on the blind hole 31, and the boss 33 makes the height of the bolt hole higher than the height of the blind hole 31, so as to prevent rainwater from flowing into the blind hole 31, and a waterproof rubber ring is provided in the boss 33 to increase the sealing between the boss 33 and the bolt 32.

[0033] Embodiment 2:

[0034] See also Figure 6 and Figure 7, the difference between this embodiment and embodiment 1 is that a first contact 34 is provided on the boss 33, a second contact matching the first contact 34 is provided on the bolt 32, and an indicator light 35 is provided on the handle 3. The indicator light 35 is electrically connected to the first contact 34, and the indicator light 35 is normally open. After the first contact 34 contacts the second contact, the indicator light 35 goes out. Since the device is easily vibrated during transportation, the bolt 32 is easy to gradually loosen, causing rainwater to penetrate into the bolt 32 and the blind hole rivet nut column 21 and cause corrosion. At the same time, when the bolt 32 is screwed into the blind hole rivet nut column 21, the bolt 32 may not be screwed into the appropriate position, causing the bolt 32 to be easy to loosen, and it is possible that the bolt 32 is screwed in when the bolt 32 is misaligned and the thread is slipped, resulting in loosening due to vibration in the later stage. Therefore, the first contact 34 and the second contact are set to detect the screwing-in condition of the bolt 32. When the bolt 32 is screwed into the blind hole rivet nut column 21, the second contact on the bolt 32 will contact the first contact 34, thereby disconnecting the circuit of the indicator light 35. At this time, it means that the bolt 32 has been screwed to the appropriate position. At the same time, if the bolt 32 is misaligned and stripped, the second contact on the bolt 32 is in an inclined state and will not contact the first contact 34. Therefore, when the indicator light 35 is off, it can also be used to detect whether the bolt 32 is misaligned and stripped. Furthermore, when the bolt 32 vibrates and loosens, the second contact will move away from the first contact 34, so that the indicator light 35 lights up again to remind the user that the bolt 32 is loose.

[0035] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
