Technical Field

[0001] The utility model relates to the field of battery module structures, in particular to a battery module structure with high grouping rate and high safety. Background Art

[0002] The world today faces three major problems: energy shortage, excessive carbon dioxide emissions, and air pollution. In 2050, the world's oil resources will be close to exhaustion, and the crisis and exhaustion of non-renewable energy such as oil, coal and natural gas will eventually be inevitable. Excessive carbon dioxide emissions will cause the "greenhouse effect". The exhaust pollution caused by traditional fuel vehicles is one of the main sources of air pollution. How to solve the problem of automobile exhaust has attracted more and more attention from governments around the world. Therefore, new energy vehicles have come into being. As the core component of new energy vehicles, new energy batteries have increasingly higher safety and reliability requirements.

[0003] However, the safety performance of general battery modules on the market is not very good, which leads to the possibility that the battery module may rupture or even explode when it is violently impacted during use, thus posing a certain threat to people's lives and property. Therefore, the existing battery modules cannot meet people's usage needs, bringing inconvenience to people's work and life. At the same time, the soft-pack lithium-ion batteries on the market require more additional structural parts when grouped than the square aluminum shell batteries, so that the efficiency of the soft-pack lithium-ion batteries on the market is generally lower than that of the square aluminum shell lithium-ion batteries when grouped.

[0024] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0025] Reference Figure 1-4 The utility model provides an embodiment: a high grouping rate and high safety battery module structure, including a shell 1, a battery module 7 is arranged inside the shell 1, slots 11 are opened at the upper and lower ends of the inner side of the shell 1, a driving motor 13 is fixedly connected inside the slot 11, and a bidirectional screw 14 is fixedly connected to the output end of the driving motor 13, and the bidirectional screw 14 can be rotated by starting the driving motor 13. The shell 1 adopts a square aluminum shell battery module outer frame, combined with the use of structural adhesive, and a single-head output ear soft-pack battery cell is symmetrically packaged without bottom sealing by aluminum-plastic film, and the aluminum shell of the single battery is removed. The battery cell inside the single battery is packaged by aluminum-plastic film, thereby greatly reducing the amount of aluminum alloy used in the battery module, improving the overall grouping rate of the battery module, and realizing the ultra-high grouping rate of solid-state soft-pack batteries. Compared with square aluminum shell batteries, the application is more flexible;

[0026] Two threaded blocks 15 are threadedly connected on the bidirectional screw 14. The upper end of the threaded block 15 passes through the slot 11 and a clamping plate 6 is arranged upward. Under the action of the threaded connection, the threaded block 15 can drive the clamping plates 6 at both ends to move relative to each other, so that the battery module can be positioned and clamped, so that the battery module can be better protected when a violent impact occurs, so that it will not break or explode, etc., making people feel more at ease when using it, further meeting people's use needs, bringing convenience to people's work, and at the same time eliminating the silicone pads and aerogel and other foaming materials between the battery cells to reduce costs; the battery cells are partially directly connected with glue to ensure the overall strength of the module; other gap areas are separated by air to reserve space for the battery cell to expand when the battery cell reaches the end of its cycle life. At the same time, the thermal conductivity of air is very low, which can reduce the heat transferred to the adjacent battery cell when the battery cell is thermally runaway, thereby improving its heat dissipation effect;

[0027] An air inlet assembly 5 is provided at one end of the housing 1, and a heat dissipation hole 8 is provided at the other end of the housing 1. A driving structure and a fan structure are arranged inside the air inlet assembly 5, and cold air from the outside can be sent into the interior of the housing 1 through the air inlet hole 4.

[0028] A plurality of air inlet holes 4 are provided inside the air inlet assembly 5, and a U-shaped frame 3 is fixedly connected to the outside of the air inlet assembly 5. A dustproof mesh plate 2 is correspondingly provided inside the U-shaped frame 3, and slide grooves 10 are provided at both ends of the dustproof mesh plate 2. Slide blocks 9 are fixedly connected to both ends of the inner side of the U-shaped frame 3, and the slide blocks 9 are slidably connected inside the slide grooves 10. Latch pins 16 are movably connected to both ends of the U-shaped frame 3, and a groove 12 is provided inside the slide groove 10. The latch pin 16 corresponds to the groove 12, and a spring 17 is sleeved on the latch pin 16. The dust in the air can be intercepted by providing the dustproof mesh plate 2, thereby preventing dust from entering the inside of the housing 1 and attaching to the battery module 7 to cause damage thereto. At the same time, the latch pin 16, the groove 12, the slide groove 10 and the slide block 9 can facilitate the staff to regularly disassemble and clean the dustproof mesh plate 2, thereby improving the dustproof effect of the dustproof mesh plate 2;

[0029] A positioning groove 19 is provided at the inner bottom of the U-shaped frame 3, and a positioning block 18 is fixedly connected to the lower end of the dustproof mesh plate 2. The positioning block 18 corresponds to the positioning groove 19. By setting the positioning block 18 and the positioning groove 19, the dustproof mesh plate 2 can be quickly positioned, thereby improving the practicability and convenience of the device.

[0030] Working principle: When the device is used, the battery modules are first installed, and then the battery modules are placed inside the shell 1. A wiring hole is set at the rear end of the shell 1, and the battery module can be connected through the wiring hole to achieve its normal power supply operation. Then, starting the drive motor 13 can drive the bidirectional screw 14 to rotate. Under the action of the threaded connection, the threaded block 15 can drive the clamping plates 6 at both ends to move relative to each other, so that the battery module can be positioned and clamped, so that the battery module can be better protected when a violent impact occurs, so that it will not break or explode, etc., making people feel more at ease when using it, further meeting people's use needs, and bringing convenience to people's work. At the same time, the battery module 7 will generate heat during operation. At this time, starting the air intake device inside the air intake assembly 5 can send the cold air from the outside into the shell 1 through the air inlet hole 4 to cool the battery module 7 and dissipate the heat. At the same time, the internal heat can be discharged through the heat dissipation hole 8 to achieve its air-cooled circulation heat dissipation operation.

[0031] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
