Example one

Referring to fig. 1, an installation structure 10 of a battery assembly 20 according to an embodiment of the present disclosure includes a first connection mechanism 11, a second connection mechanism 12, and a support rod 13, where the first connection mechanism 11 is used to connect the battery assembly 20, the second connection mechanism 12 is used to connect a protruding portion 201 of a color steel tile 200, and the support rod 13 is disposed between the first connection mechanism 11 and the second connection mechanism 12, and is used to maintain a distance between the first connection mechanism 11 and the second connection mechanism 12, and to prop open the battery assembly 20 and the protruding portion 201.

The mounting structure 10 of the battery assembly 20 of the embodiment of the present application, because the supporting rod 13 is utilized to keep the distance between the first connecting mechanism 11 and the second connecting mechanism 12, and the protruding portion 201 of the battery assembly 20 and the color steel tile 200 is opened, a heat dissipation channel and a drainage channel can be formed between the battery assembly 20 and the color steel tile 200, the temperature of the battery assembly 20 is reduced, the permeation corrosion of water vapor to the battery assembly 20 is slowed down, and the reliability and the service life of the battery assembly 20 are favorably improved.

It is understood that the battery assembly 20 generates heat during operation, which results in a reduction in the power generation efficiency of the battery assembly 20 and even in the occurrence of fire by firing the assembly. In the present application, since the heat dissipation channel is formed between the battery assembly 20 and the color steel tile 200, the battery assembly 20 can dissipate heat better, and the battery assembly 20 can be ensured to work at a proper temperature, thereby being beneficial to improving the power generation efficiency of the battery assembly 20.

It is understood that if there is no drainage channel between the battery assembly 20 and the color steel tile 200, the assembly is prone to water accumulation, and water vapor easily permeates the back plate of the battery assembly 20 and corrodes the battery assembly 20, and the risk of electric leakage is increased. In the present application, since the drainage channel is formed between the battery assembly 20 and the color steel tile 200, the battery assembly 20 can drain water better, and the battery assembly 20 can be ensured to work under a proper humidity, so as to avoid corrosion or electric leakage.

Specifically, the first connecting mechanism 11 may be bonded, snapped, riveted, screwed, or otherwise connected to the battery assembly 20. The first connecting mechanism 11 may be fixedly connected with the battery assembly 20. Thus, the relative position relationship between the first connecting mechanism 11 and the color steel tile 200 is relatively fixed, and the stability of the battery assembly 20 in the first connecting mechanism 11 can be ensured. The first connecting mechanism 11 may also be movably connected to the battery assembly 20. For example, the battery pack 20 is rotatably connected to the first connecting mechanism 11; as another example, the battery assembly 20 is slidably coupled to the first coupling mechanism 11. The specific form of connection of the first connecting mechanism 11 and the battery assembly 20 is not limited herein. Thus, the battery assembly 20 can be flexibly adjusted in orientation and position to receive sunlight.

Specifically, the second connecting mechanism 12 can be bonded, snapped, riveted, screwed or otherwise connected to the protruding portion 201 of the color steel tile 200. The second connecting mechanism 12 can be fixedly connected with the convex portion 201 of the color steel tile 200. Therefore, the relative position relationship between the second connecting mechanism 12 and the color steel tile 200 is relatively fixed, and the stability of the second connecting mechanism 12 in the setting of the color steel tile 200 can be ensured. In other embodiments, the second connecting mechanism 12 can also be movably connected with the convex portion 201 of the color steel tile 200.

Specifically, the top and bottom surfaces of the support bar 13 abut against the first and

second connection mechanisms

11 and 12, respectively. The top and bottom surfaces of the first connecting mechanism 11 abut against the battery pack 20 and the support rod 13, respectively. The top and bottom surfaces of the second connecting mechanism 12 respectively abut against the supporting rod 13 and the convex portion 201 of the color steel tile 200. In this way, the top surface of the support rod 13 is abutted against the battery assembly 20 through the first connecting mechanism 11, and the bottom surface of the support rod 13 is abutted against the protrusion 201 through the second connecting mechanism 12, so that the battery assembly 20 and the protrusion 201 can be maximally spread, and the heat dissipation channel and the drainage channel can be maximally formed.

Specifically, the support rod 13 may have a cylindrical or prismatic shape. Therefore, the shape of the support rod 13 is regular, the manufacture is convenient, the stress is uniform when the battery component 20 is supported, and the risk of fracture of the support rod 13 is reduced.

Specifically, the support rod 13 may be an iron rod or a galvanized steel rod. Thus, the support rod 13 is made of a rigid material and is not easily deformed.

Specifically, the length of the support rod 13 may be fixed. In this manner, the distance between the battery assembly 20 and the boss 201 is fixed. It is understood that in other embodiments, the supporting rod 13 can be a telescopic rod, and the length can be varied within a certain range. In this manner, the adjustment of the distance between the battery assembly 20 and the boss 201 is more flexible, thereby making the formation of the heat dissipation channel and the drainage channel more flexible.

Therefore, the friction force between the supporting rod 13 and the first groove 1111 can be increased, and the supporting rod 13 is prevented from sliding out of the first groove 1111. It will be appreciated that the stud may be formed with the groove wall of the first recess 1111, or may be formed on both the support bar 13 and the groove wall of the first recess 1111.

It is understood that the first grooves 1111 may also have an elongated shape, and each of the first grooves 1111 corresponds to one or more supporting rods 13. Therefore, strip-shaped supports are formed on the battery component 20, so that the stress area can be increased, and the component deformation can be reduced.

Specifically, the first grooves 1111 include aluminum alloy grooves, nylon 66 grooves, carbon fiber grooves, and the like. Therefore, the first groove 1111 has high strength and is not easy to deform.

Meanwhile, the bulge 201 can be accommodated in the third groove 1212, which can adapt to the shape of the bulge 201, avoid great damage to the bulge 201, and enable the color steel tile 200 to have good waterproofness.

Specifically, one end of the support rod 13 facing the protrusion 201 may be cylindrical. Therefore, the shape is simple, the manufacturing is convenient, and the production efficiency is favorably improved. It is understood that an end of the support rod 13 facing the boss 201 may be formed with a boss having a cross-sectional area smaller than that of the support rod 13, the boss being inserted into the second groove 1211.

Specifically, the surface of the support bar 13 facing one end of the boss 201 may be formed with a plurality of anti-slip protrusions. Thus, the friction between the supporting rod 13 and the second groove 1211 can be increased, and the supporting rod 13 can be prevented from sliding out of the second groove 1211. It will be appreciated that the stud may be formed on the walls of the second recess 1211 as well, or on both the support rod 13 and the second recess 1211.

Specifically, the second grooves 1211 include aluminum alloy grooves, nylon 66 grooves, carbon fiber grooves, and the like. Thus, the second groove 1211 is high in strength and not easy to deform.

Specifically, the groove wall of the third groove 1212 may be formed with a non-slip protrusion. Thus, the friction force between the third groove 1212 and the boss 201 is increased, and the third groove 1212 is prevented from slipping out of the boss.

Specifically, the protrusion 201 may be bonded, snapped, riveted, screwed, or otherwise connected with the third groove 1212.

Specifically, the number of the third grooves 1212 may be block-shaped, strip-shaped, or other shapes. The specific shape of the third groove 1212 is not limited herein.
