Description

Technical Field

[0001] This utility model relates to the field of lithium battery assembly technology, and specifically to a lithium battery protection assembly device. Background Technology

[0002] Lithium-based batteries are divided into lithium batteries and lithium-ion batteries. Mobile phones and laptops use lithium-ion batteries, which are commonly referred to as lithium batteries. These batteries generally use materials containing lithium as electrodes and are representative of modern high-performance batteries. However, true lithium batteries are rarely used in everyday electronic products due to their high risk. A more widely used type is the cylindrical lithium battery, which can be assembled in multiple stages to meet the voltage requirements of different power supplies.

[0003] However, in actual use, when assembling cylindrical battery bodies, care must be taken to protect the batteries. Existing assembly devices usually assemble individual batteries one by one, which results in low actual assembly efficiency. At the same time, traditional battery protection assembly devices usually install and protect multiple batteries together through an external battery casing, thus lacking the restriction and protection of multiple individual batteries. Therefore, a structure that facilitates assembly while providing group protection for batteries is needed. Utility Model Content

[0004] The purpose of this invention is to provide a lithium battery protection assembly device that solves the existing problems of lithium batteries needing to be easily and quickly assembled and installed, and needing to be able to fix and protect the batteries separately.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a lithium battery protection assembly device, comprising a mounting frame, a central column and a lithium battery, wherein multiple central columns are arranged in an array inside the mounting frame, multiple lithium batteries are arranged around the bottom outer wall of the central column, and a baffle is provided at the top of the inside of the mounting frame.

[0006] The bottom end of the mounting frame is fixedly connected to a base plate, and the top of the inside of the base plate is provided with a central groove, and multiple threaded grooves are arranged in an array inside the central groove.

[0007] The bottom of the outer wall of the central column is provided with multiple receiving grooves, and the inside of the receiving grooves is arc-shaped. A connecting rod is provided through the center of the central column.

[0008] The sidewall of the lithium battery fits into the interior of the receiving groove, and a protective sleeve is provided around the outer wall of the central column near the top of the lithium battery.

[0009] Preferably, the interior of the mounting frame is engaged with the outer edge of the baffle, and the interior of the baffle has multiple central holes, the positions of which correspond to the connecting rods.

[0010] Preferably, the top of the connecting rod is engaged with the baffle via a knob, and the bottom of the connecting rod is threaded around it, with the bottom of the connecting rod being threadedly connected to the inside of the threaded groove.

[0011] Preferably, the inner edge of the central groove is arc-shaped, the bottom of the lithium battery is in contact with the inside of the central groove, and multiple blocking pillars are arranged in an array inside the central groove, with the blocking pillars in contact with the sidewall of the lithium battery.

[0012] Preferably, the top of the inner wall of the mounting frame is provided with a slot that corresponds to the edge of the baffle, the bottom of the baffle is fixedly connected to the protective sleeve, the top of the mounting frame is provided with a cover plate, the bottom of the baffle is pressed against the top of the central column, and the top of the central column is pressed against the top of the lithium battery.

[0013] Preferably, the protective sleeve has a square cross-section, the inner wall of the protective sleeve is in close contact with the lithium battery surrounding the central column, and multiple protective sleeves are in close contact with each other.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. Lithium batteries are placed into the protective sleeves at the bottom of the baffles. Since multiple protective sleeves are fixedly connected to the baffles, they correspond to each other and form a larger set. The lithium batteries to be assembled in the receiving slots outside the central column can then be connected and fixed to the baffles through the connection of multiple protective sleeves. This allows for easy removal of the corresponding baffle and placement inside the mounting frame during installation. By setting multiple baffles, assembly can be completed quickly. At the same time, since the bottom of the baffles restricts the position of the lithium batteries through the protective sleeves, the lithium batteries can be easily placed in a fixed position in one go. Furthermore, since the bottom of the mounting frame has a central slot, the installation position of the lithium batteries can be further restricted by the blocking post to prevent them from tilting and facilitate installation.

[0016] 2. The connecting rod is inserted into the center column, connecting the bottom of the connecting rod to the threaded groove inside the center slot. Then, the baffle is pulled upwards to release the engagement between the center hole inside the baffle and the top of the connecting rod. The connecting rod is then rotated, connecting it to the threaded groove. This causes the connecting rod to press the center column downwards, which in turn presses the lithium battery into place. Simultaneously, the baffle is moved downwards to further press and fix the center column, and the center hole engages with the top of the connecting rod, thus securing the connecting rod and preventing reverse rotation. This further maintains the fixation of the center column and the compression fixation of the lithium battery. Multiple protective sleeves also provide spacing protection between multiple lithium batteries. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5The lithium battery protection assembly device shown includes a mounting frame 1, a central column 2, and a lithium battery 3. Multiple central columns 2 are arranged in an array inside the mounting frame 1. Multiple lithium batteries 3 are arranged around the bottom outer wall of the central columns 2. A baffle 4 is provided at the top inside the mounting frame 1. A base plate 101 is fixedly connected to the bottom end of the mounting frame 1, and a central groove 102 is formed at the top inside the base plate 101. Multiple threaded grooves 103 are arranged in an array inside the central groove 102. Multiple receiving grooves 202 are formed around the bottom outer wall of the central column 2, and the interior of the receiving grooves 202 is arc-shaped. A connecting rod 201 is inserted through the center of the interior of the central column 2. The sidewalls of the lithium batteries 3 are in close contact with the interior of the receiving grooves 202. A protective sleeve 301 is arranged around the outer wall of the central column 2 near the top of the lithium batteries 3.

[0027] like Figure 1 , Figure 2 As shown, the interior of the mounting frame 1 and the outer edge of the baffle 4 are correspondingly engaged. The interior of the baffle 4 has multiple central holes 401, and the positions of the central holes 401 correspond to the connecting rod 201. The top of the inner wall of the mounting frame 1 has a slot that corresponds to the edge of the baffle 4. The bottom of the baffle 4 is fixedly connected to the protective sleeve 301. A cover plate is installed on the top of the mounting frame 1. The bottom of the baffle 4 is pressed against the top of the central column 2. The top of the central column 2 is pressed against the top of the lithium battery 3. Pulling the baffle 4 upward releases the engagement between the central hole 401 inside the baffle 4 and the top of the connecting rod 201. Then, the connecting rod 201 is rotated so that the connecting rod 201 is threadedly connected to the threaded groove 103. This causes the connecting rod 201 to press the central column 2 downward, which in turn causes the central column 2 to press the lithium battery 3, thus fixing the lithium battery 3. At the same time, the baffle 4 is moved downward to further press and fix the central column 2.

[0028] like Figure 2 , Figure 5 As shown, the top of the connecting rod 201 is engaged with the baffle 4 via a knob, and the bottom of the connecting rod 201 is threaded around it. The bottom of the connecting rod 201 is threadedly connected to the inside of the threaded groove 103. The inner edge of the central groove 102 is arc-shaped, and the bottom of the lithium battery 3 fits into the inside of the central groove 102. Multiple blocking posts 104 are arranged in an array inside the central groove 102. The blocking posts 104 fit into the side wall of the lithium battery 3, which can easily place the lithium battery 3 in a fixed position at once. Furthermore, since the bottom of the mounting frame 1 has a central groove 102, the blocking posts 104 can further restrict the installation position of the lithium battery 3, preventing it from tilting and facilitating installation.

[0029] like Figure 3 , Figure 4As shown, the protective sleeve 301 has a square cross-section. The inner wall of the protective sleeve 301 is in close contact with the lithium battery 3 surrounding the outside of the central column 2. Multiple protective sleeves 301 are close to each other. The lithium battery 3 is placed into the protective sleeve 301 at the bottom of the baffle 4. Since multiple protective sleeves 301 are fixedly connected to the baffle 4, the multiple protective sleeves 301 correspond to the baffle 4 and form a larger group. At this time, the lithium battery 3 assembled in the receiving groove 202 outside the central column 2 can be connected to the multiple protective sleeves 301, and thus the lithium battery 3 is connected and fixed to the baffle 4.

[0030] During use, the corresponding lithium battery 3 can be easily engaged with the receiving groove 202 on the bottom outer wall of the central column 2, allowing multiple lithium batteries 3 to be conveniently grouped together with one central column 2. During installation, the lithium batteries 3 can be easily placed into the protective sleeves 301 at the bottom of the baffle 4. Since multiple protective sleeves 301 are fixedly connected to the baffle 4, they correspond to each other, forming a larger group. The lithium batteries 3 assembled in the receiving groove 202 on the outside of the central column 2 can then be engaged with the multiple protective sleeves 301. The lithium battery 3 is interconnected with the baffle 4, thus achieving interconnection and fixation. During installation, the corresponding baffle 4 can be easily picked up and placed inside the mounting frame 1. By setting multiple baffles 4, assembly can be completed quickly. At the same time, since the bottom of the baffle is restricted by the protective sleeve 301, the lithium battery 3 can be easily placed in a fixed position at once. Furthermore, since the bottom of the mounting frame 1 is provided with a central groove 102, the installation position of the lithium battery 3 can be further restricted by the blocking post 104 to prevent it from tilting and facilitate installation.

[0031] During the fixing process, the connecting rod 201 is inserted into the center column 2, so that the bottom of the connecting rod 201 is connected to the threaded groove 103 inside the center groove 102. Then, the baffle 4 is pulled upward to release the engagement between the center hole 401 inside the baffle 4 and the top of the connecting rod 201. Then, the connecting rod 201 is rotated, so that the connecting rod 201 and the threaded groove 103 are threaded together. This causes the connecting rod 201 to press the center column 2 downward, which in turn causes the center column 2 to press the lithium battery 3, thus fixing the lithium battery 3. At the same time, the baffle 4 is moved downward to further press and fix the center column 2, and the center hole 401 is engaged and fixed with the top of the connecting rod 201, thus fixing the connecting rod 201 and preventing it from rotating in the opposite direction. This further maintains the fixation of the center column 2 and achieves the compression and fixation of the lithium battery 3. In addition, multiple protective sleeves 301 can also provide spaced protection between multiple lithium batteries 3.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
