Description

Technical Field

[0001] This utility model relates to the technical field of energy storage power supply, and in particular to a portable energy storage power supply. Background Technology

[0002] Currently, to meet certain household electricity needs during times of power shortage (such as power outages), household emergency energy storage power supplies are available on the market. These power supplies typically consist of a battery and a power outlet, providing 220V household voltage to meet the power requirements of some household appliances.

[0003] Chinese utility model CN222106938U discloses a portable energy storage power supply, which features a conveniently movable mechanism. The principle is based on a support rod embedded and rotated inside the base, with a roller at one end of the support rod. A telescopic rod is also installed inside the base. In use, simply rotate the support rod to unfold the stored support rod, and simultaneously pull the telescopic rod out from inside the base. The wheel at one end of the support rod facilitates movement.

[0004] However, existing devices require lifting the energy storage power source and rotating and unfolding the bottom support rod during use. Since the energy storage power source is essentially a large battery, it is quite heavy and difficult to move. Furthermore, after unfolding the support rod, a telescopic rod needs to be pulled, making operation inconvenient. Therefore, a roller structure was designed to address the aforementioned problems and facilitate operation. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0026] The current technology works by embedding a rotating support rod inside a base, with a roller at one end of the rod. A telescopic rod is also located inside the base. To use it, simply rotate the support rod to unfold it, and then pull the telescopic rod out of the base. The wheels at one end of the support rod facilitate movement. However, existing devices require lifting the energy storage power source to rotate and unfold the support rod. Since the energy storage power source is essentially a large battery, it is quite heavy and difficult to move. Furthermore, pulling the telescopic rod after unfolding the support rod makes the operation inconvenient.

[0027] As shown in the attached figures, this embodiment of the present invention provides a portable energy storage power supply.

[0028] The device includes: a base 11 with a power storage body 12 fixedly mounted on its top; a telescopic assembly 2 disposed inside the base 11, the telescopic assembly 2 including: a support rod 21 with one end inserted into the interior of the base 11; a wheel 22 fixedly mounted on one end of the support rod 21; a rack 23 fixedly mounted on the top of the support rod 21; a gear 24 rotatably mounted inside the base 11 and meshing with the rack 23; a second rack 25 disposed inside the base 11 and meshing with the gear 24; and a pull rod 26 with one end inserted into the interior of the base 11 and fixedly connected to one end of the second rack 25.

[0029] Specifically, the principle of the energy storage power supply body 12 mainly includes four parts: power conversion unit, power management unit, power storage unit, and power supply unit. The power conversion unit converts external electrical energy into electrical energy that can be stored in the battery; the power management unit manages the charging and discharging process of the battery; the power storage unit is composed of batteries and stores electrical energy; and the power supply unit converts the stored electrical energy into the form of electricity required by various electrical appliances.

[0030] Common energy storage power supply models include lithium-ion batteries, lead-acid batteries, lithium iron phosphate batteries, and sodium-sulfur batteries.

[0031] The internal rotation of gear 24 is provided with a vertical rod, which is connected by an attachment Figure 3 This demonstrates that the two ends of the upright are fixedly connected to the inner side wall of the base 11, and because the gear 24 is rotatably connected to the upright, the gear 24 is rotatably set inside the base 11.

[0032] When the energy storage power unit 12 needs to be moved during use, the pull rod 26 can be pulled out from the base 11, which will drive the rack 25 to move inside the base 11. While moving, the rack 25 will mesh with the gear 24 and drive the gear 24 to rotate. As the gear 24 rotates, it can mesh with the rack 23, thereby pushing the support rod 21 to extend from the base 11. After both the support rod 21 and the pull rod 26 have extended from the base 11, the pull rod 26 can be dragged so that the wheel 22 at one end of the support rod 21 contacts the ground. The energy storage power unit 12 can be moved using the wheel 22, which is more labor-saving than manual transport.

[0033] In some embodiments, the telescopic assembly 2 further includes a handle 27 fixedly disposed at one end of the pull rod 26.

[0034] The handle 27 is designed for easy gripping and facilitates pulling the lever 26 out of the base 11.

[0035] In some embodiments, the telescopic assembly 2 further includes: a positioning hole 28 formed on the outer side wall of the pull rod 26; and a pin 29, the bottom end of which is inserted into the interior of the positioning hole 28.

[0036] After the pull rod 26 is pulled out from inside the base 11, the bottom end of the pin 29 can be inserted into the positioning hole 28 to stabilize the pull rod 26 and prevent it from retracting into the base 11, thus making it more convenient to use.

[0037] In some embodiments, the telescopic component 2 further includes a rubber block 291 fixedly disposed at the bottom end of the pin 29.

[0038] When the rubber block 291 is placed inside the through positioning hole 28, it will be squeezed and contracted. After passing through the positioning hole 28, it will block the pin 29 to a certain extent, making it difficult for it to detach from the positioning hole 28.

[0039] In some embodiments, the rubber block 291 has a tapered shape.

[0040] The tapered bottom tip design makes insertion into the positioning hole 28 relatively easier.

[0041] In some embodiments, the telescopic assembly 2 further includes: the two ends of the connecting rope 292 are fixedly connected to the top of the pin 29 and the outer side wall of the base 11, respectively.

[0042] The connecting cord 292 is designed to connect the pin 29, making it less likely to be lost.

[0043] In some embodiments, the base 11 is provided with a spring-loaded assembly 3 inside, and the spring-loaded assembly 3 further includes: a protrusion 31 fixedly disposed at the bottom of the rack 25; and a spring 32 disposed inside the base 11, and both ends of the spring 32 being fixedly connected to the inner sidewall of the base 11 and the protrusion 31 by means of retaining rings.

[0044] Specifically, both ends of the spring 32 are fixedly connected by retaining rings. The retaining rings are a commonly used fixing structure for existing springs 32 and are not shown in the attached drawings.

[0045] When the lever 26 is pulled out, it will drive the rack 25 to move, and at the same time drive the protrusion 31 to move, which will compress the spring 32. When the lever 26 is pushed into the base 11 after use, the spring 32 will rebound and push the protrusion 31 to move. The rebound force of the spring 32 can make it easier to push the lever 26.

[0046] In some embodiments, the rebound assembly 3 further includes: one end of a crossbar 33 passing through the protrusion 31 and the spring 32, and both ends of the crossbar 33 being fixedly connected to the inner sidewall of the base 11.

[0047] The design of the crossbar 33 allows the protrusion 31 to slide on the crossbar 33, stabilizing the movement of the rack 25, while preventing the spring 32 from being compressed, thus further protecting the spring 32.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
