Description

Technical Field

[0001] The present application relates to the technical field of mobile power supplies, and in particular to a trolley-type photovoltaic energy storage battery. Background Art

[0002] With the rapid development of renewable energy technology, photovoltaic energy storage batteries, as a green and renewable energy storage device, have been widely used in outdoor adventures, emergency rescue, field operations, and home backup power.

[0003] A Chinese utility model patent, publication number CN221353029U, discloses a trolley-type photovoltaic energy storage battery. The cooling fan can quickly remove heat from the two heat-dissipating sides of the inverter module, while also blowing directly into the cooling air duct to better dissipate internal heat and prevent the temperature inside the box from activating a high-temperature alarm. However, while this trolley-type photovoltaic energy storage battery utilizes cooling fans to optimize internal thermal management, it often overlooks the protection of the fan's heat dissipation vents, a critical component. This is particularly true regarding the impact of environmental factors on battery performance and safety. In complex and changing outdoor environments, natural factors such as dust and moisture can easily enter the battery through the fan's heat dissipation vents, leading to decreased battery performance, shortened battery life, and even potential safety hazards.

[0004] Therefore, the present application provides a trolley-type photovoltaic energy storage battery to solve the above problems. Utility Model Content

[0005] The present application provides a trolley case-type photovoltaic energy storage battery, which aims to solve the problems raised in the background technology, that is, although the existing trolley case-type photovoltaic energy storage battery optimizes the internal thermal management, it ignores the protection of the heat dissipation vents of the heat dissipation fan, allowing environmental factors such as dust and moisture to easily invade the interior, affecting the battery performance and life and posing a safety hazard.

[0006] To achieve the above objectives, the present application provides the following technical solution: a trolley-type photovoltaic energy storage battery, comprising a housing, a battery pack fixedly disposed within the housing, a telescopic pull rod fixedly mounted on the housing, brake wheels fixedly disposed at the corners of the bottom of the housing, and cooling fans fixedly mounted at both sides of the housing for dissipating heat inside the housing;

[0007] The trolley case photovoltaic energy storage battery further includes a dustproof filter and / or a waterproof breathable membrane provided at the air outlet of the heat dissipation fan, and a mounting structure provided on the outside of the housing for disassembling and mounting the filter and / or the waterproof breathable membrane;

[0008] The mounting structure includes a heat dissipation cover fixedly arranged on the outside of the shell and connected to the air outlet of the heat dissipation fan, at least two slots opened in the heat dissipation cover, an opening opened on the top of the heat dissipation cover for inserting the filter and / or waterproof breathable membrane into the slot, and a sealing cover adapted to the opening; by arranging the mounting structure and the replaceable filter and / or waterproof breathable membrane at the air outlet position of the heat dissipation fan, the user can choose appropriate protective measures according to different usage environments. For example, in a dusty environment, a filter can be installed to prevent dust from entering, and in a humid or rainy environment, a waterproof breathable membrane can be installed to prevent moisture from penetrating. This design can effectively prevent these harmful substances from entering the battery, thereby protecting the battery pack from damage and improving the safety and adaptability of the trolley case-type photovoltaic energy storage battery.

[0009] Preferably, in order to ensure the stability and sealing of the sealing cover installation, fastening bolts are provided on both sides of the sealing cover, and the sealing cover is fixedly connected to the heat dissipation cover by fastening bolts; the sealing cover is firmly fixed to the heat dissipation cover by fastening bolts, which can ensure the sealing of the opening position and at the same time increase the stability of the sealing cover installation to prevent the loosening of the installation structure during the movement or transportation of the trolley box-type photovoltaic energy storage battery.

[0010] Preferably, in order to facilitate the operation of the fastening bolt, a knob is fixedly provided on the side of the fastening bolt away from the sealing cover; the design of the knob makes the tightening and loosening operations of the fastening bolt simpler and faster, and the user does not need to use additional tools, but only needs to rotate the knob to complete the tightening or loosening of the bolt, which greatly improves the convenience of operation.

[0011] Preferably, in order to further facilitate the disassembly and assembly of the filter screen and the waterproof breathable membrane, the installation structure also includes a clamping plate assembly respectively arranged in the two slots for clamping the filter screen and / or the waterproof breathable membrane; the presence of the clamping plate assembly makes the disassembly and assembly process of the filter screen and the waterproof breathable membrane simpler and faster, thereby enhancing the maintainability of the equipment.

[0012] Preferably, in order to facilitate quick operation, the clamping plate assembly includes two magnetic plates arranged in parallel in the slot and magnetically attracted to each other, and the filter screen or waterproof breathable membrane is placed between the two magnetic plates; the magnetic plates attract each other through magnetic force and can quickly and firmly clamp the filter screen or waterproof breathable membrane. The user does not need to use additional tools or complicated operations, but simply places the filter screen or waterproof breathable membrane between the two magnetic plates, and they will automatically adsorb and clamp, thereby greatly simplifying the disassembly and assembly process.

[0013] Preferably, in order to further ensure the sealing of the filter and the waterproof breathable membrane, a sealing gasket in contact with the outer side of the magnetic plate is fixedly installed on the inner wall of the slot; the sealing gasket can fit tightly between the inner wall of the slot and the magnetic plate, providing an additional sealing layer, thereby further effectively preventing external impurities such as dust, moisture, and air from penetrating into the battery pack through tiny gaps.

[0014] This suitcase-type photovoltaic energy storage battery is equipped with a mounting structure and a replaceable filter and / or waterproof breathable membrane at the air outlet of the cooling fan. Users can choose appropriate protective measures according to different usage environments. This design can effectively prevent these harmful substances from entering the battery, thereby protecting the battery pack from damage and improving the safety and adaptability of the suitcase-type photovoltaic energy storage battery.

[0015] The trolley-type photovoltaic energy storage battery is equipped with a splint assembly, which makes the disassembly and assembly process of the filter and waterproof breathable membrane simpler and faster, further enhancing the maintainability of the equipment.

[0030] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] Example 1

[0032] This embodiment provides a pull-bar box type photovoltaic energy storage battery, such as Figure 1-5 As shown, the trolley case type photovoltaic energy storage battery includes a shell 1, a battery pack 2 fixedly arranged in the shell 1, a telescopic pull rod 3 fixedly mounted on the shell 1, brake wheels 4 fixedly arranged at the corners around the bottom of the shell 1, and cooling fans 5 fixedly mounted at both sides of the shell 1 for dissipating heat inside the shell 1; the trolley case type photovoltaic energy storage battery also includes a dust-proof filter 6 and / or a waterproof breathable membrane 7 for waterproofing arranged at the air outlet of the cooling fan 5, and a mounting structure 8 arranged on the outside of the shell 1 for disassembling and assembling the filter 6 and / or the waterproof breathable membrane 7; the mounting structure 8 includes a cooling cover 81 fixedly arranged on the outside of the shell 1 and connected to the air outlet of the cooling fan 5, at least two slots 82 opened in the cooling cover 81, an opening 83 opened at the top of the cooling cover 81 for inserting the filter 6 and / or the waterproof breathable membrane 7 into the slot 82, and a sealing cover 84 adapted to the opening 83.

[0033] During use, the telescopic pull rod 3 is used to move the trolley box-type photovoltaic energy storage battery to the required position. After moving to the determined position, the box is locked by the brake wheel 4 to prevent it from sliding or rolling. Then, according to the use environment, the sealing cover 84 can be opened, and the filter 6 and / or the waterproof breathable membrane 7 can be inserted into the corresponding slot 82 through the opening 83. After completing the insertion of the filter 6 and / or the waterproof breathable membrane 7, the sealing cover 84 is fixed at the opening 83 and ensure that the opening 83 is sealed. Afterwards, during the use of the trolley box-type photovoltaic energy storage battery, the cooling fan 5 will continue to discharge the heat inside the shell 1 from the cooling cover 81, and the external air will be filtered and / or blocked by the filter 6 and / or the waterproof breathable membrane 7, effectively preventing dust and / or moisture from entering the shell 1 and damaging the battery pack 2.

[0034] Specifically, fastening bolts 841 are provided on both sides of the sealing cover 84, and the sealing cover 84 is fixedly connected to the heat dissipation cover 81 through the fastening bolts 841, wherein a knob 842 is fixedly provided on the side of the fastening bolt 841 away from the sealing cover 84;

[0035] After the filter 6 and / or the waterproof breathable membrane 7 are inserted into the slot 82 and the sealing cover 84 is inserted into the opening 83, the fastening bolt 841 can be rotated to further fix the sealing cover 84 on the heat dissipation cover 81. When the filter 6 and / or the waterproof breathable membrane 7 needs to be disassembled, the knob 842 can be rotated in the opposite direction to loosen the fastening bolt 841, thereby releasing the fixation between the sealing cover 84 and the heat dissipation cover 81 and easily pulling the sealing cover 84 out from the opening 83.

[0036] Example 2

[0037] Unlike Example 1, to further facilitate assembly and disassembly of the filter 6 and the waterproof breathable membrane 7, the mounting structure 8 further includes a clamping plate assembly 85 disposed in the two slots 82 for clamping the filter 6 and / or the waterproof breathable membrane 7. The clamping plate assembly 85 includes two magnetic plates 851 disposed parallel to the slots 82 and magnetically attracted to each other. The filter 6 or the waterproof breathable membrane 7 is placed between the two magnetic plates 851.

[0038] When the filter 6 and / or the waterproof breathable membrane 7 needs to be inserted into the slot 82, first place the filter 6 and / or the waterproof breathable membrane 7 between the corresponding two magnetic plates 851, then magnetically attract the two magnetic plates 851, and the filter 6 and / or the waterproof breathable membrane 7 can be easily clamped between the two magnetic plates 851. Then, the entire clamping plate assembly 85 and the filter 6 and / or the waterproof breathable membrane 7 fixed on the clamping plate assembly 85 are inserted into the slot 82 from the opening 83, and finally the opening 83 is sealed by the sealing cover 84. When the filter 6 and / or the waterproof breathable membrane 7 needs to be removed, the seal between the sealing cover 84 and the opening 83 can be released first, and then the clamping plate assembly 85 can be removed from the opening 83. Then, the two magnetic plates 851 can be gently pulled to fall off, and the clamped filter 6 or waterproof breathable membrane 7 can be easily removed.

[0039] In addition, in order to further ensure the sealing of the filter 6 and the waterproof breathable membrane 7, a sealing gasket 821 is fixedly installed on the inner wall of the slot 82 and contacts the outer side of the magnetic plate 851; the sealing gasket 821 can fit tightly between the inner wall of the slot 82 and the magnetic plate 851, providing an additional sealing layer, thereby further effectively preventing external impurities such as dust, moisture, and air from penetrating into the battery pack 2 through tiny gaps.

[0040] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
