Description

Technical Field

[0001] This utility model relates to the field of energy storage battery technology, specifically to an outdoor photovoltaic integrated machine energy storage battery. Background Technology

[0002] Energy storage batteries are key devices for storing electrical energy in renewable energy systems, primarily used in solar and wind power generation equipment. This product type includes lead-acid batteries (including vented, valve-regulated, and gel types) and lithium-ion batteries (with lithium iron phosphate as a representative technology). In 2022, energy storage battery shipments reached 130 GWh, a year-on-year increase of 170.8%. Technical specifications require both 2V and 12V DC voltage options, wide operating temperature range of -30℃ to 60℃, and must pass testing by national certification bodies.

[0003] Most existing outdoor photovoltaic integrated energy storage batteries are equipped with casters at the bottom. The original intention of this design is to improve the mobility of the equipment and make it easier for users to adjust the position of the battery according to the lighting conditions or usage scenarios. At the same time, the casters also integrate a self-locking function to fix the position when the equipment is stationary.

[0004] However, in actual use, this design has obvious flaws. In order to ensure the battery life, the energy storage battery module usually has a large capacity battery cell, and the overall weight is relatively large, generally reaching tens or even hundreds of kilograms. When the equipment is in operation, even if the casters are locked, the weight of the battery itself will exert continuous pressure on the wheel locking structure. In addition, the slight slope or vibration of the outdoor ground may easily cause the locking function to fail, resulting in the equipment sliding or shifting at will. This not only affects the alignment efficiency of the photovoltaic panel, but may also bring safety hazards. Summary of the Invention

[0005] The purpose of this invention is to provide an outdoor photovoltaic integrated energy storage battery to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an outdoor photovoltaic integrated energy storage battery, including a support frame, a universal wheel fixedly connected to the bottom of the support frame, a support plate fixedly connected to the top of the support frame, a support mechanism provided at the bottom of the support plate, a shell fixedly connected to the top of the support plate, a battery module provided inside the shell, and a connecting mechanism provided on the surface of the shell; The support mechanism includes a limiting plate, which is fixedly connected to the support frame. The top and bottom of the limiting plate are fixedly connected to a fixing frame. A threaded rod is rotatably connected in the middle of the fixing frame. A horizontal plate is threadedly connected to the surface of the threaded rod. Vertical plates are fixedly connected to both sides of the bottom of the horizontal plate. A support base is fixedly connected to the bottom of the vertical plate.

[0007] Preferably, two threaded rods are provided, and the two threaded rods are symmetrically arranged. The surfaces of the two threaded rods are connected to a pulley set with a triangular design. The triangular pulley set can ensure the stability and synchronization of the transmission, so that the two threaded rods can rotate at the same time and at the same speed. This ensures the consistency of movement of the subsequent horizontal plate, vertical plate and support base, and avoids the equipment tilting or unstable support due to uneven force on one side.

[0008] Preferably, the pulley assembly is connected to an output shaft on the side away from the threaded rod. A motor is fixedly connected to the bottom of the output shaft and fixedly connected to the top of the support frame. The motor serves as a power source, driving the pulley assembly to rotate through the output shaft, thereby driving the threaded rod to rotate. This achieves automated adjustment of the support mechanism without manual operation, improving the convenience of lifting and adjusting the support seat and adapting to the support needs of different outdoor ground surfaces.

[0009] Preferably, two support seats are provided, which are symmetrically arranged at the bottom of the support frame. The two symmetrical support seats can provide stable support points when the equipment is placed. In conjunction with the casters, the equipment can be moved easily, and when fixed, the support seats can enhance the overall stability and prevent the equipment from shaking or tipping over outdoors due to external forces (such as wind or collisions).

[0010] Preferably, the connection mechanism includes an inverter, which is fixedly connected to the top of the battery module by fixing bolts. The inverter converts the DC power stored in the battery module into AC power to meet the AC power requirements of outdoor equipment. The fixing bolts ensure that the inverter and the battery module are firmly connected and prevent the connection from becoming loose due to vibration during movement or use.

[0011] Preferably, a partition is fixedly connected in the middle of the housing, and the battery modules are all arranged on both sides of the partition. The partition serves to separate and fix the battery modules, which can prevent multiple battery modules from squeezing and colliding with each other, while facilitating heat dissipation of the battery modules, reducing heat accumulation caused by dense arrangement, and ensuring the working efficiency and service life of the battery modules.

[0012] Preferably, a photovoltaic interface is fixedly connected to the surface of the outer casing, and AC, 12VDC, and USB output ports are also fixedly connected to the surface of the outer casing. The photovoltaic interface on the surface of the outer casing is used to connect a photovoltaic panel to realize the input of solar energy to the battery module to complete energy storage. The AC, 12VDC, and USB output ports correspond to the power supply requirements of AC power, 12V DC power, and USB devices, respectively, enriching the output methods of the device and meeting the power needs of different outdoor electrical appliances (such as lamps, small household appliances, digital products, etc.), thereby improving the practicality and versatility of the device.

[0013] Compared with the prior art, this utility model provides an outdoor photovoltaic integrated energy storage battery, which has the following beneficial effects: 1. Under the force applied by the support base, the universal wheels of this outdoor photovoltaic integrated energy storage battery are suspended in the air, which can ensure that the battery module will not move randomly during operation, thus improving the effectiveness of the device.

[0014] 2. The outdoor photovoltaic integrated energy storage battery integrates the inverter on the top of the battery module, eliminating the need for an external inverter. It can achieve AC / DC conversion and photovoltaic voltage stabilization, simplifying the connection and operation process, reducing the overall cost of the equipment, reducing safety hazards caused by external connection cables, and improving the convenience and reliability of the equipment.

[0015] 3. The outdoor photovoltaic integrated machine's energy storage battery is equipped with an AC output interface, a 12V DC output interface, and a USB output interface, which can meet the power supply needs of different types of electrical devices, such as household appliances, vehicle devices, mobile phones, tablets, etc., and has a wide range of applications; and the battery module specifications are 51.2V 100AH, with an energy storage capacity of 5KWH, which can provide sufficient power to meet the needs of long-term outdoor power use.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides a technical solution: Example

[0020] Combination Figures 1 to 2 -3, an outdoor photovoltaic integrated energy storage battery, including a support frame 1, a universal wheel 6 fixedly connected to the bottom of the support frame 1, a support plate 4 fixedly connected to the top of the support frame 1, a support mechanism 2 provided at the bottom of the support plate 4, a shell 5 fixedly connected to the top of the support plate 4, a battery module 7 provided inside the shell 5, and a connecting mechanism 3 provided on the surface of the shell 5. The support mechanism 2 includes a limiting plate 27, which is fixedly connected to the support frame 1. The top and bottom of the limiting plate 27 are fixedly connected to a fixing frame 22. A threaded rod 21 is rotatably connected in the middle of the fixing frame 22. A horizontal plate 26 is threadedly connected to the surface of the threaded rod 21. Vertical plates 25 are fixedly connected to both sides of the bottom of the horizontal plate 26. A support seat 23 is fixedly connected to the bottom of the vertical plate 25.

[0021] Furthermore, two threaded rods 21 are provided, and the two threaded rods 21 are symmetrically arranged. The two threaded rods 21 are connected to a pulley set with a triangular design. The triangular pulley set can ensure the stability and synchronization of the transmission, so that the two threaded rods 21 can rotate at the same time and at the same speed. This ensures the consistency of movement of the subsequent horizontal plate 26, vertical plate 25 and support base 23, and avoids the equipment tilting or unstable support due to uneven force on one side.

[0022] Furthermore, an output shaft is connected to the pulley assembly on the side away from the threaded rod 21. A motor 24 is fixedly connected to the bottom of the output shaft. The motor 24 is fixedly connected to the top of the support frame 1. The motor 24 serves as a power source, driving the pulley assembly to rotate through the output shaft, thereby driving the threaded rod 21 to rotate. This enables the automatic adjustment of the support mechanism 2 without manual operation, improving the convenience of lifting and adjusting the support base 23 and adapting to the support needs of different outdoor ground surfaces.

[0023] Furthermore, two support bases 23 are provided, which are symmetrically arranged at the bottom of the support frame 1. The two symmetrical support bases 23 can provide stable support points when the equipment is placed. In conjunction with the casters 6, they can facilitate the movement of the equipment and enhance the overall stability when the equipment is fixed, preventing the equipment from shaking or tipping over outdoors due to external forces (such as wind or collisions).

[0024] Example 2: See Figure 4 Furthermore, based on Embodiment 1, the connection mechanism 3 includes an inverter 32. The inverter 32 is fixedly connected to the top of the battery module 7 by fixing bolts. The function of the inverter 32 is to convert the DC power stored in the battery module 7 into AC power to meet the AC power requirements of outdoor equipment. The fixing bolts ensure that the inverter 32 and the battery module 7 are firmly connected to avoid loosening of the connection due to vibration during movement or use.

[0025] Furthermore, a partition 33 is fixedly connected in the middle of the outer casing 5, and the battery modules 7 are all arranged on both sides of the partition 33. The partition 33 serves to separate and fix the battery modules 7, which can prevent multiple battery modules 7 from squeezing and colliding with each other, while facilitating heat dissipation of the battery modules 7, reducing heat accumulation caused by dense arrangement, and ensuring the working efficiency and service life of the battery modules 7.

[0026] Furthermore, a photovoltaic interface 31 is fixedly connected to the surface of the outer casing 5, and AC, 12VDC, and USB output ports 34 are also fixedly connected to the surface of the outer casing 5. The photovoltaic interface 31 on the surface of the outer casing 5 is used to connect the photovoltaic panel to realize the input of solar energy to the battery module 7 to complete energy storage; the AC, 12VDC, and USB output ports 34 correspond to the power supply needs of AC power, 12V DC power, and USB devices, respectively, enriching the output methods of the device, meeting the power needs of different outdoor electrical appliances (such as lamps, small household appliances, digital products, etc.), and improving the practicality and versatility of the device.

[0027] In actual operation, the device can be moved to a suitable position by the caster wheel 6. After being moved to a suitable position, the motor 24 is started. Under the linkage formed by the pulley group, the threaded rods 21 on both sides can be driven to rotate synchronously. During the synchronous rotation of the threaded rods 21 on both sides, the support base 23 can be driven to move downward, so that the support base 23 is close to the ground. At this time, under the force applied by the support base 23, the caster wheel 6 is suspended in the air, which can ensure that the battery module 7 will not cause the device to move randomly during operation, thus improving the use effect of the device. Based on the above principles, it can be seen that by repeating the opposite steps, the support base 23 can be moved upward, and the caster 6 can contact the ground, thereby achieving the purpose of moving the device, which is highly practical. Integrating the inverter 32 on the top of the battery module 7 eliminates the need for an external inverter 32, enabling AC / DC conversion and photovoltaic voltage stabilization. This simplifies the connection and operation process, reduces the overall cost of the equipment, minimizes safety hazards associated with external wiring, and enhances the ease of use and reliability of the equipment.
