Description

Technical Field

[0001] This utility model belongs to the field of battery pack technology, and specifically relates to a battery pack cooling and heat dissipation mechanism. Background Technology

[0002] A battery is an integrated energy storage device that combines multiple battery cells (cells) in series and parallel, and is equipped with a battery management system (BMS), thermal management system, structural components, and casing.

[0003] Battery packs typically use heat sinks for heat conduction, transferring heat generated during battery operation to the air. However, dust easily accumulates on these heat sinks, reducing their thermal conductivity and consequently decreasing the overall cooling performance of the battery pack. While existing heat sinks are generally fixed to the battery pack, and although battery packs offer some water resistance, cleaning the heat sinks still requires careful consideration to avoid potential risks. Therefore, this application proposes a battery pack cooling mechanism. The cooling structure, composed of a pressure plate, heat sinks, and other components, is easy to install and disassemble. After removal, the heat sinks can be washed to remove dust, cleaned, dried, and then reinstalled on the battery pack, making dust removal much easier. Utility Model Content

[0004] The purpose of this utility model is to provide a battery pack cooling and heat dissipation mechanism to solve the problem mentioned in the background art that most of the existing heat sinks are fixed on the battery pack and cannot be removed and cleaned by washing with water.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery pack cooling and heat dissipation mechanism, including a housing and a battery. The housing is provided with a storage slot for storing the battery, a cover plate is provided at the storage slot, a pressure plate is provided on the outside of the cover plate, heat dissipation fins are provided on the pressure plate, and an outer frame is provided at the pressure plate.

[0008] The pressure block has at least two states, including a locked state and an open state. When the pressure block is in the locked state, both the first connecting rod and the second connecting rod are inserted into the transverse groove. When the pressure block is in the open state, the second connecting rod is inserted into the arc-shaped groove.

[0009] Preferably, the housing is provided with an L-plate, and the storage frame is mounted on the L-plate.

[0010] Preferably, the cover plate presses against the upper side of the battery, and the housing is provided with a mounting groove that mates with the pressure plate.

[0011] Preferably, the pressure plate is located on the upper side of the cover plate, and a heat-conducting plate is provided at the bottom of the pressure plate, which is located below the heat sink.

[0012] Preferably, the heat-conducting plate is connected to the heat sink, and the heat sink penetrates the pressure plate and comes into contact with the air outside the housing.

In the locked state, the pressure block presses against the upper side of the upper clamping plate, and both the first and second connecting rods are inserted into the horizontal groove. In the open state, the first connecting rod is inserted into the horizontal groove, and the second connecting rod is inserted into the arc-shaped groove.

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] like Figures 1-5 As shown in the figure, a battery pack cooling and heat dissipation mechanism provided in this embodiment of the present invention includes a housing 1 and a battery 2. The housing 1 is provided with a storage slot for storing the battery 2, and a cover plate 3 is provided at the storage slot. (See reference...) Figure 4 , Figure 5 The cover plate 3 presses on the upper side of the battery 2. A pressure plate 4 is provided on the outer side of the cover plate 3. Several heat sinks 5 are provided on the pressure plate 4 at intervals. An installation groove 101 that cooperates with the pressure plate 4 is provided inside the housing 1.

[0029] It should be noted that the pressure plate 4 is located on the upper side of the cover plate 3, and a heat-conducting plate is provided at the bottom of the pressure plate 4. The heat-conducting plate is located below the heat sink 5 and is connected to the heat sink 5. The heat sink 5 penetrates the pressure plate 4 and comes into contact with the air outside the housing 1. The heat sink 5 can come into contact with the external gas, thereby transferring the heat generated by the battery 2 during operation to the external air, achieving the purpose of heat dissipation.

[0030] To limit the distance the pressure plate 4 is inserted into the housing 1, an outer frame 6 is provided at the pressure plate 4. The size of the outer frame 6 is larger than the size of the mounting groove 101. The outer frame 6 presses against the outside of the housing 1, and the outer frame 6 is fixedly connected to the pressure plate 4. In this way, after the pressure plate 4 is inserted into the mounting groove 101, the pressure plate 4 and the outer frame 6 can only move upward.

[0031] In order to stop the outer frame 6 and the pressure plate 4 from moving upward and thus fix the position of the pressure plate 4, a limit component is provided at the position of the pressure plate 4. There are multiple sets of limit components, and the multiple sets of limit components are located at the two long sides of the pressure plate 4 respectively.

[0032] In a specific embodiment, the limiting component includes an upper clamping plate 7, a pressure block 9, a first connecting rod 11, a second connecting rod 12, and a storage frame 13. The upper clamping plate 7 is installed on the pressure plate 4. It should be noted that the pressure plate 4 has a groove, and the upper clamping plate 7 is inserted into the groove. The bottom of the upper clamping plate 7 has an inclined surface. The housing 1 has a lower clamping plate 8 at the position corresponding to the upper clamping plate 7. The upper side of the lower clamping plate 8 has a connecting surface that cooperates with the inclined surface.

[0033] For reference Figure 3 The pressure block 9 is equipped with a first connecting rod 11 and a second connecting rod 12. The storage frame 13 is provided with a horizontal groove 1301 and an arc groove 1302. The horizontal groove 1301 and the arc groove 1302 are connected. The first connecting rod 11 and the second connecting rod 12 can slide along the horizontal groove 1301. The first connecting rod 11 can rotate along the arc groove 1302. The storage frame 13 is installed on the housing 1. Specifically, the housing 1 is provided with an L plate, and the storage frame 13 is installed on the L plate.

[0034] It should be noted that a handle is provided at the second connecting rod 12, and the handle is provided with anti-slip texture. A soft pad 10 is provided on the lower side of the pressure block 9.

[0035] The first connecting rod 11 and the second connecting rod 12 can be pulled to move, thereby changing the position of the pressure block 9, so that the pressure block 9 has at least two states, including a locked state and an open state, as can be seen from [reference]. Figure 3When the pressure block 9 is in the locked state, it presses against the upper plate 7. The first connecting rod 11 and the second connecting rod 12 are both inserted into the transverse groove 1301. When the pressure block 9 is in the open state, the first connecting rod 11 is inserted into the transverse groove 1301 and the second connecting rod 12 is inserted into the arc groove 1302. In specific operation, pull the second connecting rod 12 to move the first connecting rod 11 to the right. The second connecting rod 12 reaches the position of the arc groove 1302. At this time, pull the second connecting rod 12 to lift it upward. The pressure block 9 and the upper plate 7 are vertically misaligned. At this time, the upper plate 7, the pressure plate 4, and the heat sink 5 can be pulled out from the housing 1. Simply pull the first connecting rod 11 to the far right. At this time, the pressure block 9 is still located on the upper side of the pressure plate 4. Only when the pressure block 9 is lifted upward can the pressure block 9 and the upper plate 7 be vertically misaligned.

[0036] In summary, this utility model embodiment provides a battery pack cooling and heat dissipation mechanism. The pressure block 9 has two states: a locked state and an open state. When the pressure block 9 is in the locked state, it presses against the upper side of the upper clamping plate 7, and both the first connecting rod 11 and the second connecting rod 12 are inserted into the transverse groove 1301. When the pressure block 9 is in the open state, the first connecting rod 11 is inserted into the transverse groove 1301, and the second connecting rod 12 is inserted into the arc groove 1302. When the pressure block 9 is changed from the locked state to the open state, the second connecting rod 12 is pulled, causing the first connecting rod 11 to move to the right. The second connecting rod 12 reaches the position of the arc groove 1302. At this time, the second connecting rod 12 is pulled upward, and the pressure block 9 and the upper clamping plate 7 are staggered vertically. At this time, the upper clamping plate 7, the pressure plate 4, and the heat sink 5 can be pulled out from the housing 1. This enables the locking and unlocking of the positions of the pressure plate 4 and the heat sink 5, facilitating the installation and disassembly of the heat dissipation structure composed of the pressure plate 4, the heat sink 5, and other components.

[0037] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
