In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited to the specific embodiments disclosed below;

[0026] It should be noted that the terms "first", "second", "symmetrical", "array", etc. are only used to distinguish between description and position description purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the definition of "first", "symmetrical", etc. can explicitly or implicitly include one or more of these features; similarly, when the quantity of certain features is not limited in the form of words such as "two" or "three", it should be noted that this feature also explicitly or implicitly includes one or more feature quantities;

[0027] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature; at the same time, all axial descriptions, such as the X-axis, Y-axis, Z-axis, one end of the X-axis, the other end of the Y-axis or the other end of the Z-axis, etc., are based on a Cartesian coordinate system.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood based on the description and drawings combined with specific circumstances.

[0029] See also Figure 1-5 This specific embodiment provides a protective shell of a battery pack module, including a shell assembly 10, the shell assembly 10 includes a protective shell 11, a first threaded hole 12, a positioning hole 13, a guide rod 14, a threaded rod 15, a connecting block 16, a slider 17, a support plate 18, a sealing strip 19, a sprocket 110, a chain 111 and a pad 112;

[0030] The inner wall of the protective shell 11 is symmetrically rotatably connected to two threaded rods 15, and a connecting block 16 is fixedly connected to the top of one of the threaded rods 15. The outer walls of the two threaded rods 15 are fixedly connected to a sprocket 110, and the two sprockets 110 are connected by a chain 111. The outer wall of the threaded rod 15 is threadedly connected to a slider 17, and a support plate 18 is fixedly connected between the two sliders 17. A sealing strip 19 is fixedly connected to the upper surface of the support plate 18, and four pads 112 are symmetrically fixedly connected to the bottom of the inner wall of the protective shell 11.

[0031] Specifically, four first threaded holes 12 are symmetrically arranged inside the protective shell 11 , and two positioning holes 13 are symmetrically arranged inside the protective shell 11 . The first threaded holes 12 and the second threaded holes 22 are used to fix the protective shell 11 and the top cover 21 by bolts.

[0032] Specifically: two guide rods 14 are symmetrically fixedly connected to the inner side wall of the protective shell 11, and the support plate 18 is slidably connected to the outer side wall of the guide rod 14. The guide rod 14 is used to assist the support plate 18 to move up and down.

[0033] Specifically: a cover assembly 20 is disposed on the top of the housing assembly 10, and the cover assembly 20 includes a top cover 21, a second threaded hole 22, a through hole 23, a positioning column 24 and a sealing cover 25;

[0034] A top cover 21 is fixedly connected to the top of the protective housing 11 by bolts, and the top cover 21 is used to close the protective housing 11 .

[0035] Specifically, four second threaded holes 22 are symmetrically fixedly connected to the upper surface of the top cover 21 .

[0036] Specifically, two positioning posts 24 are symmetrically fixedly connected to the lower surface of the top cover 21 , and the top cover 21 is conveniently aligned with the protective shell 11 through the cooperation between the positioning posts 24 and the positioning holes 13 .

[0037] Specifically, a through hole 23 is formed on the upper surface of the top cover 21 , and the through hole 23 is used to make room for the connecting block 16 .

[0038] Specifically: A sealing cover 25 is fixedly connected to the lower surface of the top cover 21, and the sealing cover 25 is arranged opposite to the sealing strip 19. The sealing cover 25 cooperates with the sealing strip 19 to make the protective shell have a double sealing structure. At the same time, there is a certain space between the double sealing structures, which makes it difficult for moisture to enter the interior of the sealing cover 25, thereby improving the waterproof effect of the protective shell.

[0039] When the utility model is in operation, the battery pack module is installed on the support plate 18, and then the protective shell is installed on the equipment. When the battery pack module needs to be inspected and replaced, the top cover 21 is opened, and the connecting block 16 is rotated by a wrench to rotate the threaded rod 15. The two threaded rods 15 cooperate with the sprocket 110 and the chain 111 to keep synchronous rotation, thereby driving the slider 17 and the support plate 18 to move upward, and the internal battery pack module is extended from the inside of the protective shell 11, which is convenient for the staff to disassemble and take the battery pack module without removing the protective shell, saving time. The sealing cover 25 cooperates with the sealing strip 19 to make the protective shell have a double sealing structure. At the same time, there is a certain space between the double sealing structures, which makes it difficult for moisture to enter the inside of the sealing cover 25, thereby improving the waterproof effect of the protective shell.

[0040] The above-mentioned embodiments only express the implementation methods of the relevant practical applications of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
