DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0022] Refer to Figures 1-2The utility model provides an embodiment: a kind of installation of convenient family energy storage battery pack, including protection mechanism 1, energy storage mechanism 2 is slidably arranged in protection mechanism 1, first magnetic attraction connector 3 is magnetically attracted and arranged on the side of energy storage mechanism 2, protection mechanism 1 includes protection frame 102, stable slide bar 108 is fixedly arranged in the lower end two dark groove positions of protection frame 102, two stable slide bars 108 are slidably arranged with sliding frame 105, retracting spring 109 is fixedly arranged between the position of the side of sliding frame 105 close to stable slide bar 108 and the inside of protection frame 102;

[0023] Specifically, stable slide bar 108 provides stable track for the sliding of sliding frame 105, so that it can only move along a specific direction in protection frame 102. One end of retracting spring 109 is connected with sliding frame 105, and the other end is connected with the inside of protection frame 102. When sliding frame 105 is not restricted by other external force, retracting spring 109 is in a natural extension state. When sliding frame 105 is fixed at a specific position by limiting block 111, retracting spring 109 is compressed to store elastic potential energy. Stable slide bar 108 ensures the stability and accuracy of the movement of sliding frame 105, avoids shaking or deviation during movement, and guarantees the reliability of the entire protection mechanism 1. The setting of retracting spring 109 provides automatic retracting power for sliding frame 105. When limiting block 111 is released, sliding frame 105 can be quickly pulled into protection frame 102, realizing quick isolation of faulty battery from the outside world, and greatly improving the protection efficiency.

[0024] Refer to Figures 1-4 The inside of both sides of sliding frame 105 is embedded with limiting block 111 rotatingly arranged, the side of two limiting blocks 111 away from each other is embedded with pull-out plate 112 rotatingly arranged, heat-sensitive rubber block 110 is arranged between two limiting blocks 111 and protection frame 102, mounting groove 103 is formed in both sides of sliding frame 105, spring is fixedly connected between the inside of two limiting blocks 111 and the inside of sliding frame 105, the material of two heat-sensitive rubber blocks 110 is polyvinyl alcohol glue, heat-conducting plate 101 is fixedly arranged at the position of both sides of sliding frame 105 close to limiting block 111.

[0025] Specifically, under normal conditions, the thermal sensing glue block 110 is in a solid state, fixing the limiting block 111 at a specific angle, allowing it to partially protrude from the sliding frame 105 and clamp the protective frame 102, thereby limiting the movement of the sliding frame 105. When the battery fails and the temperature rises, the heat-conducting plate 101 transfers heat to the thermal sensing glue block 110. The polyvinyl alcohol glue material of the thermal sensing glue block 110 melts at 70 degrees Celsius, losing its fixing effect on the limiting block 111. At this time, the spring connected between the inside of the limiting block 111 and the inside of the sliding frame 105 pulls the limiting block 111 back into the inside of the sliding frame 105, releasing the limiting of the sliding frame 105. The pull-out plate 112 can be used when manually operating the limiting block 111 is needed. By pulling the pull-out plate 112, the limiting block 111 can be rotated, facilitating manual adjustment of the position of the sliding frame 105 in special situations. The installation slot 103 can be used to install other auxiliary equipment or for structural connection. The combination of the thermal sensing glue block 110 and the limiting block 111 and related springs realizes an automatic protection function based on temperature changes. Without additional electronic sensors and complex circuit control, the system's reliability and stability are greatly improved by relying on simple physical principles to accurately respond to high temperatures caused by battery failures, triggering the protection mechanism. The heat-conducting plate 101 speeds up the heat transfer rate, allowing the thermal sensing glue block 110 to more quickly perceive temperature changes, improving the timeliness of protection. The pull-out plate 112 provides convenience for manual intervention, increasing the flexibility of operation and meeting the needs of different scenarios. The installation slot 103 provides more possibilities for functional expansion and installation methods of the equipment.

[0026] The sliding frame 105 is embedded with a heat dissipation plate 106 at the front end, and the heat dissipation plate 106 is made of aluminum oxide. The sliding frame 105 is fixedly provided with a push-pull handle 107 at the front end, and the protective frame 102 is fixedly provided with a mounting bracket 104 at the rear end on both sides.

[0027] Specifically, the battery generates heat during operation, and the aluminum oxide material of the heat sink 106 has good thermal conductivity, which can quickly conduct the heat generated by the battery to the surface of the heat sink 106, and then dissipate to the surrounding environment through air convection and radiation. The push-pull handle 107 facilitates the user to manually push the sliding frame 105, and in the case of normal installation, maintenance or debugging, etc. need to move the sliding frame 105, the user can easily operate through the push-pull handle 107. The mounting bracket 104 is used to fix the protection frame 102 in a suitable position in the home, such as a wall, a support, etc. It is fixed by passing through the mounting hole on the mounting bracket 104 with a bolt or other fixing member. The aluminum oxide material of the heat sink 106 can efficiently dissipate the heat of the battery, effectively reduce the working temperature of the battery, improve the performance and service life of the battery, and reduce the risk of failure caused by overheating. The design of the push-pull handle 107 makes the operation of the sliding frame 105 more convenient, and enhances the convenience of the user. The mounting bracket 104 provides a standardized interface for the installation of the entire protection mechanism 1, which facilitates flexible installation according to different home environments and layouts, and improves the applicability of the product.

[0028] Referring to Figure 2 The energy storage mechanism 2 includes an energy storage battery body 203, the material of the energy storage battery body 203 is a lithium iron phosphate battery, the upper end of the energy storage battery body 203 is provided with a handle groove 202, the inside of the handle groove 202 is fixedly provided with a pull handle 201, the two sides of the energy storage battery body 203 are both fixedly provided with a limiting block 204, the inside of one side of the energy storage battery body 203 is slidably embeddedly provided with an expansion block 205, and the inside of the expansion block 205 is embeddedly provided with a second magnetic attraction connector 206.

[0029] Specifically, the lithium iron phosphate battery as the material of the energy storage battery body 203 has high energy density, good charge and discharge performance and safety. The lifting handle 201 is located in the handle groove 202, which facilitates the user to lift or carry the energy storage battery body 203 for installation, replacement and other operations. The limiting block 204 cooperates with the sliding frame 105 to ensure the stability of the position of the energy storage battery body 203 in the sliding frame 105 during normal operation. When the sliding frame 105 slides into the protective frame 102, the telescopic block 205 will be extruded and slide inward on one side of the energy storage battery body 203, thereby causing the first magnetic contact 3 and the second magnetic contact 206 to separate, achieving power failure. The characteristics of the lithium iron phosphate battery enable the energy storage mechanism 2 to efficiently store and release electrical energy, meeting the household electricity demand, and its good safety also provides protection for household use. The design of the lifting handle 201 and the handle groove 202 greatly facilitates the user to carry and operate the energy storage battery body 203, reducing the labor intensity. The limiting block 204 ensures the stability of the energy storage battery body 203 in the sliding frame 105, avoiding the influence of battery performance due to shaking and other factors during normal operation. The cooperation of the telescopic block 205 and the magnetic contact realizes automatic power failure when the battery fails, preventing further expansion of the fault and ensuring the safety of household electricity.

[0030] Working principle: In normal working condition, the energy storage mechanism 2 is placed inside the protection mechanism 1 and connected with the protection frame 102 through the sliding frame 105. At this time, the limiting blocks 204 on both sides of the energy storage battery body 203 cooperate with the sliding frame 105 to keep stable. The heat generated by the battery can be dissipated to the outside through the heat dissipation plate 106 embedded in the front end of the sliding frame 105, ensuring the normal working temperature of the battery. The user can operate the energy storage battery body 203 through the handle groove 202 of the lifting handle 201, such as installation, maintenance, etc. At the same time, the first magnetic contact 3 is magnetically connected with the second magnetic contact 206 on one side of the energy storage mechanism 2, realizing circuit conduction and providing power for household loads.

[0031] When the battery fails and the internal temperature rises sharply, the heat-conducting plate 101 fixedly arranged at both sides of the sliding frame 105 near the limiting block 111 rapidly transfers heat to the heat-sensitive glue block 110. The material of the heat-sensitive glue block 110 is polyvinyl alcohol glue, which will rapidly melt when the heat-conducting plate 70 reaches 70 degrees Celsius. At this time, the limiting block 111 originally limited by the heat-sensitive glue block 110 is pulled back into the sliding frame 105 under the action of the internal spring, and the limiting of the sliding frame 105 is released. Then, the contraction spring 109 releases the elastic potential energy, and the sliding frame 105 is quickly pulled into the protective frame 102, so that the faulty battery is isolated from the external environment. During the sliding process of the sliding frame 105, the telescopic block 205 on one side of the energy storage battery body 203 is extruded and retracted into the limiting block 204, causing the first magnetic attraction connector 3 and the second magnetic attraction connector 206 to separate and fall off, realizing automatic power-off and avoiding further expansion of the fault. The mounting rack 104 fixedly arranged at the rear end of both sides of the protective frame 102 can be used to install the entire protection mechanism 1 in a suitable position, facilitating overall layout and use.

[0032] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application, for the skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
