[0037] As described in the background art, photovoltaic power sources are large in size and weight, and users often need to carry additional equipment for transportation and installation, which brings great inconvenience to use.

[0038] In order to solve this technical problem, the utility model provides a portable energy storage power supply, which is used for convenient transportation of the energy storage power supply.

[0041] The utility model provides a portable energy storage power source, which forms a bottom support structure by forming a triangular structure with a support rod 301 and an electric push rod 304. At the same time, the electric push rod 304 forms a semi-self-locking structure with the assistance of the side of the groove 302, making the bottom support more firm.

[0042] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0043] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0044] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0045] Example 1

[0046] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a portable energy storage power supply, the switching device 3 also includes two pins 308 fixedly connected to both sides of the outer wall of the penetration block 307, and a slot 309 is opened on the support block 306.

[0047] The combination of the latch 308 and the slot 309 on the support block 306 forms a shock-absorbing assembly composed of the buffer spring 305 and the electric push rod 304, which transforms the vibration of the entire device during movement, while preventing the power supply in the power box 408 from being damaged.

[0048] The switching device 3 further comprises a U-shaped lock seat 310 fixedly connected to the outer wall of the positioning seat 1 , and a U-shaped lock head 311 is slidably connected in the U-shaped lock seat 310 .

[0049] The U-shaped lock seat 310 and the U-shaped lock head 311 form a limiting ring to temporarily limit the position of the support rod 301. At the same time, the U-shaped lock seat 310 and the U-shaped lock head 311 form a limiting ring to ensure that the power box 408 will not rotate at the hinge when used as a tire.

[0050] Example 2

[0051] The portable energy storage power supply provided in Example 1 is further optimized. Specifically, Figure 4 , Figure 5 and Figure 6 As shown,

[0052] The heat dissipation device 4 includes a side plate 401 fixedly connected to one side of the positioning seat 1 , a circular through groove is formed on the side plate 401 , two wheels 402 are rotatably connected to the side plate 401 via bearings, and tooth grooves 403 are formed on the wheels 402 .

[0053] The heat dissipation device 4 also includes a gear ring 404 rotatably connected to the inner wall of the side plate 401 , a connecting rod 405 is fixedly connected to the gear ring 404 , a plurality of fan blades 406 are fixedly connected to the connecting rod 405 , and the fan blades 406 are rotatably connected to the protective ring 407 via bearings.

[0054] A plurality of teeth are fixedly connected to the outer side of the gear ring 404 , and the tooth grooves 403 on the wheel 402 are meshed with the teeth of the gear ring 404 .

[0055] The heat dissipation device 4 further includes a protective ring 407 fixedly connected to both sides of the circular through groove of the side plate 401 , and a power supply box 408 is hinged on the top of the support rod 301 .

[0056] The heat dissipation device 4 further includes a heat dissipation hole 409 opened on the power box 408 , and the inner circle of the power box 408 is rotatably connected to a rotating ring 410 .

[0057] The tooth grooves 403 on the wheel 402 drive the internal gear ring 404 to rotate, thereby realizing the conversion of power, making further use of the power of the wheel 402 to overcome friction, and realizing the maximization of energy utilization efficiency.

[0058] Further, such as Figure 4 , Figure 5 and Figure 6 As shown, the heat dissipation device 4 also includes a dustproof net 411 fixedly connected to the heat dissipation hole 409, an inner ring 414 is fixedly connected to the inner side of the rotating ring 410 and extends to the inside of the power box 408, and two symmetrical rectangular openings 415 are opened on the inner ring 414.

[0059] The heat dissipation device 4 further includes a power supply body 412 fixedly connected to the inner wall of the power supply box 408 , and a wiring row 413 is fixedly connected to the power supply body 412 .

[0060] By rotating the inner ring 414 inside the power box 408 to intermittently change the size of the opening between the power box 408 and the outside, the frequency of internal air pressure changes can be increased. At the same time, the rectangular opening 415 forms a concave rotating component inside to stir the internal air.

[0061] The use process of a portable energy storage power supply provided by the utility model is as follows:

[0062] 1. Under normal circumstances, Figure 2 Its state can be observed. At this time, since the power box 408 is a circular component that acts as a tire component, the rotating ring 410 above it rotates on the ground following the friction of other wheels 402. At the same time, since the U-shaped lock seat 310 and the U-shaped lock head 311 form a closed loop, the power box 408 cannot rotate relative to the support rod 301, and the movement range of the support rod 301 is limited. The pin 308 is fixed to the positioning seat 1 through the through block 307. After the pin 308 fixes the slot 309 on the limit block 303, it forms the following Figure 3 The herringbone structure shown, in which the electric push rod 304 and the buffer spring 305 form a shock absorber to avoid bumps during transportation;

[0063] 2. During the transportation of the device, the wheel 402 drives the internal gear ring 404 to rotate through the tooth groove 403 above it. While the gear ring 404 rotates, the rotational force is transmitted to the fan blades 406 through the connecting rod 405, so that the fan blades 406 rotate and generate wind force and discharge it in the direction of the power box 408. The inner ring 414 in the power box 408 rotates with the rotating ring 410. At this time, the rectangular opening 415 on the inner ring 414 intermittently overlaps with the heat dissipation hole 409 and changes the internal and external air pressure conversion. At the same time, when the inner ring 414 does not rotate, that is, when the rectangular opening 415 does not overlap with the heat dissipation hole 409, the probability of dust entering the box body can be reduced. The rectangular opening 415 can also play a role in stirring the internal air while rotating with the inner ring 414, so that the internal and external air exchange is smoother;

[0064] 3. After the engagement relationship between the latch 308 and the slot 309 is released, the device as a whole can be transformed into Figure 1 and Figure 4In the second state, the electric push rod 304 pushes the extended support block 306 to the ground, and the buffer spring 305 is transformed to reduce the vibration generated during use. The electric push rod 304 forms a right-angle semi-self-locking state under the restriction of the limit block 303 and the groove 302 for bottom support. Since the power box 408 can still rotate in this state, the rotatable U-shaped lock head 311 and the U-shaped lock seat 310 form an annular structure, and the annular structure and the two through blocks 307 form a triangular structure to support the power box 408.

[0065] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.
